A study published this week could help doctors to identify patients with brain injuries, in seemingly unresponsive states, who are more likely to recover.

In the study, published in the journal Brain on Monday, researchers identified what may be the source of a curious phenomenon known as "hidden consciousness" or cognitive motor dissociation (CMD).

Hidden consciousness is seen in patients with acute brain injury who appear to be in a coma or other unresponsive state.

Patients with CMD seem to be able to hear and comprehend verbal commands even though they cannot carry out those instructions because the body does not respond, study author Jan Claassen, a researcher at Columbia University and critical care neurologist at New York-Presbyterian/Columbia University Irving Medical Center, said in a statement.

The CMD phenomenon has only been identified in the past few years and is still poorly understood.

Methods have been developed to detect CMD in unresponsive patients. These include analyzing changes in electrical activity or cerebral blood flow recorded by an electroencephalogram (EEG) or functional magnetic resonance imaging (fMRI) respectively. But both of these methods currently have their limitations.

Nevertheless, it is thought that around 15 to 20 percent of patients who appear to be in a coma or another unresponsive state display signs of CMD when evaluated with such methods, Claassen told Newsweek. The detection of CMD is reshaping our understanding of patients in comatose or other unresponsive states.

Associated With Recovery of Consciousness

Clinicians define when a patient is in a "coma" purely based on the clinical examination, Claassen said. They apply this label to patients who display a complete absence of arousal (for example, eye opening) and awareness.

Patients with CMD do not seem to be able to follow commands and may in clinical examination appear to be in a coma.

But an analysis of EEG or functional MRI, recorded while patients are given verbal commands, reveals that the brains of these unresponsive patients are being activated in a similar way to conscious patients, Claassen said. This supports the interpretation that patients with CMD are to some degree conscious.

Identifying patients with CMD has important clinical implications for interactions, communication with families and the guidance of therapeutic decisions, according to the study.

Importantly, in prior research, Claassen and colleagues have been able to associate CMD with the recovery of consciousness and long-term recovery of independence in brain-damaged patients.

Researchers have been trying to develop more effective screening methods to identify which patients are likely to be in a state of hidden consciousness. But progress has been hampered by the fact that the brain mechanisms underlying the phenomenon have remained a mystery. This is where the latest study comes in.

In previous research, Claassen and colleagues found that subtle brainwaves detectable with EEG are the strongest predictor of hidden consciousness and eventual recovery for patients with brain injuries.

Many Patients With Hidden Consciousness Remain Undiagnosed.

For the latest study, the scientists used EEG to examine 107 unresponsive patients with acute brain injury. Almost half of the patients appeared comatose, while one quarter were in a vegetative state—i.e. their eyes were open but they could not follow commands.

The remaining patents were in a minimally conscious state—meaning they could track an examiner with their eyes or look at them but were not able to follow any commands.

Using the EEG, scientists can identify when patients are trying, but are unable, to respond to a command such as "keep opening and closing your right hand."

This method detected CMD in 21 of the patients. The scientists then analyzed structural MRI brains scans from all the patients.

Using a special analysis technique, the team were able to identify patterns of brain injury that the patients with CMD shared and contrast those to the individuals who did not display signs of hidden consciousness.

The researchers found that all of the CMD patients had intact brain structures related to arousal and command comprehension. This supports the idea that they were able to hear and understand the verbal commands.

But they also found that the CMD patients had damage to brain regions responsible for integrating and carrying out motor commands, which is why they were unable to take action.

"Our study suggests that patients with hidden consciousness can hear and comprehend verbal commands, but they cannot carry out those commands because of injuries in brain circuits that relay instructions from the brain to the muscles," Claassen said in the statement.

The findings could lead to more frequent and earlier diagnosis of CMD. This, in turn, could help better predict which brain-injured individuals are more likely to recover with rehabilitation, according to the scientists.

More research is required before the approaches documented in the study can be applied to clinical practice. But the latest study shows that it may be possible to screen for CMD using widely available structural brain-imaging techniques.

Due to the technical complexity of CMD detection, at this time it is only available in a few academic centers. As a result, the vast majority of patients with hidden consciousness in the United States and around the world remain undiagnosed.

"Not every critical care unit may have resources and staff that is trained in using EEG to detect hidden consciousness, so MRI may offer a simple way to identify patients who require further screening and diagnosis," Claassen said in the statement.

Killexams : Peer-Guided Study Groups

Peer Guided StudyPeer-Guided Study Groups help you stay on track in challenging courses. Study Group students come together weekly throughout the quarter, in small, comfortable learning communities, to boost their learning and support their course success.

How do they work?

Students enrolled in an array of first-and second-year courses have the option of enrolling in a Peer-Guided Study Group alongside the course. Study Group participants meet weekly in groups of about 5 to 7 with a peer facilitator — another student who has taken and done well in the course (or, in some cases, an equivalent course). In the two-hour meetings, students talk through key concepts from the course, ask questions on points of confusion and help answer one another’s questions, and work through practice problems or exercises together. The Study Groups are highly collaborative, comfortable environments where undergraduates can learn from one another and help one another succeed.

My Study Group was beyond amazing. It was the epitome of learning and doing. It helped me do really well on my quizzes and homework, and the group as a whole really bonded!”

Marina Siqueira, class of 2022

The study group definitely helped me stay focused on the course, and it helped me figure out my weak points and then ask questions to solidify my understanding.”

Courtlyn Brown, class of 2025

The Study Group made a massive lecture class feel more personable, by giving us a smaller venue where we could talk about the concepts and our own reactions to the material.”

Nathan Friedle, class of 2022

I was able to ask my questions in a non-judgmental group setting, which allowed me to really continue to ask until I was certain I understood the concepts.”

Sarah Eisenman, class of 2022

Talking to other students in the Study Group, and working through problems together, was a really effective way for me to understand the material.”

Deborah Shoola, class of 2020

What courses do they cover?

Peer-Guided Study Groups are available for the following courses:

  • Biology 201, 202, 203, and 301 (Molecular Biology, Cell Biology, Genetics & Evolution, Principles of Biochemistry)
  • Chemistry 110, 131, 132 (General Chemistry)
  • Chemistry 151, 152 (Accelerated General Chemistry)
  • Chemistry 215-1, -2, -3 (Organic Chemistry)
  • Economics 201, 202 (Intro to Macroeconomics, Intro to Microeconomics)
  • Economics 310-1, -2 (Microeconomics)
  • Engineering Analysis 1-4 (General Engineering 205-1,2,3,4)
  • Math 220-1,-2; 228-1; Math 230-1 (Calculus)
  • Physics 130-1, -2, -3 and 135-1, -2, -3 (College Physics, General Physics)
  • Statistics 202, 210 (Intro to Statistics, Intro Statistics for the Social Sciences)

Who can join, and when can I register?

Any student enrolled in the accompanying course can join a Study Group. Students who are looking for a supportive, community-oriented learning experience and some additional support with the course may find the Study Groups particularly useful. If you are enrolled in one of the supported courses, you will receive information on registration at the beginning of the quarter.

Registration for Fall Quarter 2023 study groups is through CAESAR and begins on Wednesday, September 20. Please note that the registration window opens at 12:00am midnight between Tuesday and Wednesday. 

Study Groups will begin meeting Monday, September 25 and all sessions will be held in-person. Study Groups end Sunday, November 26.

What is the benefit?

Participants enjoy being part of a small, friendly learning community within large, rigorous courses. Having a set time to focus on the course material each week also helps participants stay on track in the course. Program evaluations show that students participating in small-group, peer-led study at Northwestern tend to find that their confidence in the course material increases, and that they Excellerate their study skills. Many students also find that they learn the material at a deeper level, and that their grades improve.

A large body of research points to many benefits of peer-based learning, including an enhanced course experience, deeper learning, and improved grade outcomes. We have also studied the impact of these programs at Northwestern – learn more about our program evaluation.

How can I become a peer facilitator?

We recruit for facilitators each spring. We look for students who have a strong command of the subject (although straight A's are not necessary), and who have good interpersonal skills and a desire to help others succeed. See our peer leader page for details.

Killexams : Researchers use artificial intelligence to help diagnose autism, study says

Researchers are proposing using artificial intelligence technology to help diagnose autism spectrum disorder.

In a exact article published in Scientific Reports, researchers from Brazil, France and Germany reportedly used magnetic resonance imaging to train a machine learning algorithm. 

The work – in which the "quantitative diagnostic method" is proposed – was based on brain imaging data for 500 people, with more than 240 that had been diagnosed with autism. 


Machine learning techniques were applied to the data.

"We began developing our methodology by collecting functional magnetic resonance imaging [fMRI] and electroencephalogram [EEG] data," Francisco Rodrigues, the last author of the article and a professor at the University of São Paulo’s Institute of Mathematics and Computer Science, explained in a statement.

"We compared maps of people with and without ASD and found that diagnosis was possible using this methodology," he added.

The machine learning algorithm was fed with the maps, and the system was able to determine which brain alterations were associated with autism with above 95% mean accuracy. 

While previous research proposes methods for diagnosing autism based on machine learning, the article notes it often uses a single statistical parameter that is not brain network organization. 

Autism is a developmental disability caused by differences in the brain. (iStock)


Analyzing the fMRI data showed changes in certain brain regions associated with cognitive, emotional, learning and memory processes, and the cortical networks of autism patients showed more segregation, less distribution of information and less connectivity compared to controls.

"Until a few years ago, little was known about the alterations that lead to the symptoms of ASD. Now, however, brain alterations in ASD patients are known to be associated with certain behaviors, although anatomical research shows that the alterations are hard to see, making diagnosis of mild ASD much harder. Our study is an important step in the development of novel methodologies that can help us obtain a deeper understanding of this neurodivergence," Rodrigues said.

The methodology is under development and will take years to implement, according to the São Paulo Research Foundation, which supported the research.


About one in 36 children has been identified with autism spectrum disorder, according to the Centers for Disease Control and Prevention. 

Diagnosing the developmental disability can be difficult because there is no medical test, like a blood test, to do so.

Killexams : How Crying Can Help You, Here Is What A Study Says

They say that there's no sense in crying over spilled milk. But what do they know? Crying can get you another glass of milk if you do it loud enough. Plus, crying may serve a real physiologic purpose, according to a study published recently in Emotion, meaning the journal and not in an Emo-kind of way.

For the study, three researchers from the University of Queensland (Leah S. Sharman, Genevieve A. Dingle, and Eric J. Vanman) and one from Tilberg University (Ad J. J. M. Vingerhoets) recruited 197 female undergraduate students. They said that they choose all women rather than including men because pilot testing of sad videos had revealed that more women than men cried or at least more women revealed that they were crying. This did not account for the men who cried inside or used some bro-language or high fives to hide the crying.

The research team then showed each of the study participants either a video that are supposed to make them feel sad (sad videos) or a video that was not supposed to elicit any emotion (neutral videos) like something from a documentary or a ted talk. Each video lasted for close to 18 minutes. After the video, the researchers noted whether or not each participant had cried while watching the video. Ultimately, 65 participants watched the neutral video, 71 watched the sad video and cried during it, and 61 watched the sad video and did not cry. Presumably, no one cried during the neutral video. But then again, actor Bryce Dallas Howard was able to cry when Conan O'Brien talked about Home Depot in this Conan clip:

Then, each participant underwent a Cold Pressor Stress Test (CPT), which involved placing the participant's left hand, up to the wrist, in cold 0° to 5°C water. Unless you are the Iceman or Killer Frost, this is supposed to be painful. The research team measured how long each participant could stay in this position until pulling her hand out of the water. During the study, the research team continuously measured each participant's heart rate and respiratory rate and periodically measured cortisol levels from saliva samples. Cortisol is a stress-hormone that's produced by the body.

Also, at four points during the study, participants answered questions from the Positive and Negative Affect Scale short form (PANAS). These questions asked the degree to which the participant was experiencing ten different emotions and to rank each on a five-point scale that ranged from a one (very slightly or not at all) to a five (extremely).

When it came to cortisol levels and how long the participants could keep their hands submerged in the cold water, the study ended up finding not much difference between the neutral video watchers, the sad video non-criers, and the sad video criers. So if you are about to dunk yourself in cold water or take a cold shower, it may not help to cry first.

But here's a difference that the study found. Are you ready? Take a deep breath. The difference was breathing rates. While watching the videos, the non-criers tended to have elevations in their breathing rates, whereas, by contrast, the criers tended to maintain their initial breathing rates. In other words, tearing up could have helped participants better control their breathing rates. This provides further evidence that crying may help you better regulate arousal, serving as an emotional release.

Another interesting finding was that right before crying, participants tended to experience decreases in their heart rates, seemingly in anticipation of the crying. Once the crying began, their heart rates then tended to creep back up but not above where their heart rates had been before everything began. This may be further evidence that crying has a beneficial regulatory effect on your physiology.

So perhaps next time you start crying you can tell people that you are regulating your physiology. You've probably heard of people saying that they had a good cry and feel better after they've let the tears flow. It can be important to find reasonable ways to periodically release your emotions. Otherwise, you may end up bottling everything up like a hot air balloon that can explode when you least expect it.

Moreover, crying can be a way of communicating. It's really the only way that babies can express their needs before they learn how to say things like "why you throwing shade on me," or "I'm not Gucci." Crying can help communicate to others that you need more sympathy, comfort, or help. Of course, this can be misused. You don't want to cry every time your order at a restaurant doesn't come out right. And of course, there is the whole concept of crocodile tears: people crying to get something when they don't really mean it.

Crying can also be a way of communicating with yourself. Even when you cry alone, you may be telling yourself about your own state because, like many people, you could be terrible at memorizing your own emotions and situation. Tears could be your body's way of saying, "hey, take a break," or "something's not right," or "take care of yourself." Tearing up can then be a way of your body literally crying out to you.

Your body is a complex system. Crying can be complex. Your tears can flow when you are very sad, very angry, or even very happy. Better understanding what causes us to cry and what happens as a result could help us better handle our emotions and stress.

Killexams : Play games to help keep dementia at bay: study

Puzzles, chess and writing journals may be more than pure amusements to pass the time. These brain activities could help reduce the risk of dementia. 

According to a exact study in JAMA Network Open, activities related to adult literacy, such as taking classes, using a computer or writing journals, as well as active mental tasks like games, cards, or crossword puzzles, were related to a reduced dementia risk over 10 years.

The study looked at 10,318 adults in Australia who were 70 years old or older, who were generally healthy and without major cognitive impairment at enrollment.

The participants who engaged in literacy activities and active mental activities had an 11% and 9% lower, respectively, risk of dementia. 

To a lesser extent, participating in creative artistic activities, such as crafts, woodwork, and painting or drawing, and in passive mental activities such as reading, watching TV or listening to  the radio was also associated with reduced dementia risk, the study found. Creative artistic and passive mental activities both conferred a 7% decrease, according to the study.

“These results suggest that engagement in adult literacy, creative art, and active and passive mental activities may help reduce dementia risk in late life,” the study said.

The people in the study who developed dementia were older, more likely to be men and have lower levels of physical activity and to be in poorer health than individuals without dementia, the study said.

In 2022, there were 55 million individuals worldwide living with dementia, with 10 million new cases emerging annually, the study said. There’s no cure for dementia. As a result, “identifying new strategies to prevent or delay dementia onset among older individuals is a priority,” the study said.

These findings can help inform strategies for dementia prevention later life in terms of modifying daily routines and activities, the study said.

Killexams : How the ‘Proust Effect’ Can Help You Study

When you need to remember something important, it makes sense to look around for hacks and tricks to maximize your recall. And plenty of those are out there, but do they actually work? One popular tip involves chewing a certain flavor of gum or spraying an specific scent in the air while you study or work, then using the same gum or scent when it’s time to perform, such as when you’re taking a text or presenting the material you went over. The tip relies on the so-called Proust Effect and if you use it, your mileage may vary.

What is the Proust Effect?

Marcel Proust, a 20th-century writer you may already be familiar with, was the man who came up with the term “involuntary memory” to describe being hit with a memory because of a scent, taste, sound, or other sense-based trigger. As a reward for his efforts, he got this effect named after himself.

It’s a real thing that happens to the best of us: A sensory stimuli, like walking by someone wearing the perfume your mom used to wear, can jolt us into a vivid memory of the past. The phenomenon has resulted in a lot of research, because it’s deeply human but also deeply physiological and scientific.

How do people use the Proust Effect to study?

When you search for studying and memory tips, this one comes up a lot. The University of Nebraska Kearney, for instance, recommends using unfamiliar scents as a “brain booster” by spraying a different scent every time you study a unique subject. Before your test in that subject, spray the corresponding scent because, they say, “this can help you recall information.”

Does the Proust Effect really work for studying and recall?

Here’s the thing: Involuntary memories are more emotional than they are practical. Research shows that olfactory cues are much more effective at triggering emotional memories than visual cues are. The scent of a spray or the taste of a gum might transport you back to when you were studying, but it’s not guaranteed to help you remember the details of what you were studying so much as make you feel the way you felt when you were doing that.

It’s similar to the idea of changing into a designated “study outfit” when it’s time to hit the books in that way: Scents can help you compartmentalize and get in the zone, which can have a positive impact on your focus and output, but they aren’t the magic cure-all to make you remember entire passages of text.

Chewing strawberry gum while you study for chemistry and again when taking your chemistry test is more likely to help you feel like you’re in your chemistry zone than anything, which, again, can be helpful. To really remember what you studied, though, make sure to double up on hacks by using a study technique, such as interleaving or the primacy effect.

Killexams : Weird Energy Storage Solutions Could Help The Grid Go Renewable

We’re all familiar with batteries. Whether we’re talking about disposable AAs in the TV remote, or giant facilities full of rechargeable cells to store power for the grid, they’re a part of our daily lives and well understood.

However, new technologies for storing energy are on the horizon for grid storage purposes, and they’re very different from the regular batteries we’re used to. These technologies are key to making the most out of renewable energy sources like solar and wind power that aren’t available all the time. Let’s take a look at some of these ideas, and how they radically change what we think of as a “battery.”

Iron Flow Batteries

Normally, the batteries we use consist of a metal or plastic case with some electrolyte inside, sandwiched between electrodes. Usually, the electrolyte is in a paste or gel form and for all intents and purposes, we think of batteries as a typically solid object, even if they’re gooey inside.

Iron flow batteries work in an altogether different fashion. They use liquid electrolyte that is pumped into a battery as needed to generate electricity. The electrolyte consists of iron ions in solution, typically in the form of aqueous solutions like iron chloride or iron sulfate.

Typical electrode materials are carbon for both the positive and negative sides, with the battery constructed as two half cells with a porous separator in between. As the battery is charged, the iron (II) ions are oxidized in the positive half-cell, giving up electrons to become iron (III) ions. In the negative half-cell, the iron (II) ions gain electrons to become iron (0), with the metallic iron plating on to the negative electrode itself. When the battery is discharged into a load, these reactions run in reverse, with the metal on the negative half-cell electrode returning to solution.

ESS has developed iron flow batteries that can fit inside shipping containers. This model can deliver 50 kW of power, and stores up to 400 kWh of energy. Credit: ESS, Inc., YouTube

Iron flow batteries have the benefit that they scale. Larger tanks and larger cells can easily be built, which is ideal for grid applications where there is a desire to store many megawatt-hours of energy. Of further benefit is the cycle life of an iron flow battery, measured anywhere from 10,000 to 20,000 cycles. That’s an order of magnitude better than most lithium-ion cells, and gives iron flow batteries a working lifetime on the order of 10 to 20 years, or even longer.

The chemicals involved are also cheap and readily available – iron and its salts being easy to source almost anywhere in the world. There is little requirement for the fancy rare-earth metals that are key to the production of high-end lithium-ion cells. Plus, the chemicals used are also safe – there’s not really anything in a iron flow battery that can explode or catch fire like other technologies.

The iron flow battery does come with some drawbacks, though. The technology simply doesn’t have the power density of lithium-ion batteries, so more space is required to build a battery capable of delivering the same power. Additionally, due to the plating reaction on the negative electrode, the iron flow battery doesn’t scale as well as some other theoretical designs. Other flow batteries only require more electrolyte to keep producing energy, with the size of the electrodes unimportant in this regard. Furthermore, while the technology stores electrical energy directly in a chemical sense, iron flow batteries are still typically less efficient than hydroelectric pumped storage, assuming suitable land is available. Advanced hydroelectric storage methods can counter this requirement, however.

Companies are developing the technology for real-world applications today. Shipping-container sized flow batteries from companies like ESS are available with capacities up to 500 kWh, with power outputs high enough to power tens of houses over a 12 hour period. Stacking multiple units into a single installation scales the capacity as needed. They’re aimed at the so-called “long term” storage market, for storing energy on the order of 4 to 24 hours. This makes them ideal for use cases like storing energy during daily solar peaks for use in the dark night time hours.

Carbon Dioxide Storage

A diagram indicating how Energy Dome’s storage facility works in charge and discharge cycles. Credit: Energy Dome, YouTube

Carbon dioxide is all around us, as a key component of the atmosphere. It’s also a gas that can readily be stored as a liquid at ambient temperature, as long as you put it under enough pressure. In this form, it takes up far less space, and there’s energy to be gained in the phase transition, too. Energy Dome is a company that identified that this property could be useful, and has developed a storage system based on the prevalent gas.

To charge the carbon dioxide “battery,” energy is applied to compress the gaseous CO2 into a liquid. The heat generated in the compression process is stored in a thermal energy storage system. To extract power, the liquid CO2 is warmed from the formerly stored heat, and allowed to expand through a turbine, which generates power. The design uses CO2 in a sealed system. The energy is stored in the pressure applied to the CO2 and in the phase change, rather than in any chemical reaction. Thus, it’s not really a “battery,” per se, any more so than hydroelectric pumped storage, but it is an energy storage system.

The system has the benefit of being constructed from simple, well-understood equipment that is already readily available. There’s nothing radical about compressing gases nor expanding them through turbines, after all. Plus, there’s no need for expensive rare earth materials or even large amounts of copper wiring, as with lithium-ion battery storage solutions.

Energy Dome is already planning a commercial deployment in the US by 2024. It has already run tests at a scale of multiple megawatts, indicating the basic principle of the technology. The company has also secured an agreement to build a facility for the Italian energy company A2A, with a 200 MWh capacity and 20 MW power delivery.

Future Realities

The fact is that as grids around the world switch to more renewable energy solutions, there will be ever-greater demands to store that energy. Traditional solutions like hydroelectric pumped storage are still relevant, as are the major lithium-ion battery installations popping up all around the world.

However, different circumstances mean that other storage technologies can also find their own niche. In particular, those that rely on cheap, readily available materials will have an advantage, particularly given the geopolitical and supply chain issues faced today. Expect more new technologies to pop up in this space as storing renewable energy becomes a key part of our electricity grid in future.

Good day, and welcome to Innovative Solutions & Support Third Quarter Fiscal 2023 Financial Results Call. (Operator Instructions) Please note that this event is being recorded.
I'd now like to turn the conference over to Mr. Shahram Askarpour, CEO. Please go ahead, sir.

Shahram Askarpour

Good morning. This is Shahram Askarpour, Chief Executive Officer of Innovative Solutions & Support. Welcome to our conference call to discuss our performance for the third quarter of fiscal 2023, current business conditions and outlook for the coming year. Joining me is Mike Linacre, our CFO.
Before we begin, I'd like Mike to read the safe harbor statement.

Michael Linacre

Thank you, Shahram, and good morning, everyone. I would remind our listeners that certain matters discussed in the conference call today, including new products and operational and financial results for future periods are forward-looking statements that are subject to risks and uncertainties that could cause real results to differ materially, either better or worse from those discussed, including the impact of the Honeywell product line license and asset acquisition and other acquisitions as well as other risks and uncertainties reflected in our company's 10-K, which is on file with the SEC and other public filings.
Now I'll turn the call back to Shahram.

Shahram Askarpour

Thank you, Mike. I will begin today with remarks on our performance in the fiscal third quarter of 2023, followed by comments on our long-term growth plan and strategy, including the exact acquisitions from Honeywell. I will then turn the call over to Mike, who will take us through the financials.
Revenues in the third quarter increased 15% to $8 million and were also up sequentially from the second quarter. This improvement was driven by the steady contribution of our production contracts and the growth in revenue from our aftermarket products, including our King Air autothrottle and flat panel displays for the air cargo market. We're also generating revenues from new programs or services including our new autothrottle installation services and ThrustSense autothrottle for the Beechcraft King Air 200 and 300 aircraft. With this new STC, has opened a new market of potentially 700 additional aircraft.
Margins were also up from a year ago, which led to another strong quarter of bottom line results. All in all, financial performance that continues to illustrate steady, profitable growth. In addition, at the end of the third quarter, we licensed and acquired several product lines from Honeywell Aerospace. The products both enhance our current offering and leverage our existing infrastructure, making this an ideal fit with the acquisition strategy we have articulated. These products can be found on literally thousands of aircraft in our target air transport and business aviation market, and we believe we have the potential to expand them into the military market as well. This acquisition, together with continued strong organic revenue represent an important inflection point in our revenue growth rate. Once fully integrated in 2024, we expect these new products to drive consolidated revenue growth to approximately 40% with an even more significant impact on earnings, where we expect EBITDA to increase by 75% with accretive EPS in 2024.
These anticipated results clearly illustrate that we are committed to our strategy to better leverage our existing infrastructure by layering on new revenues that have a similar margin profile as our existing operations, and that can utilize our current excess capacity in manufacture. The integration of these operations is proceeding as planned and is on track to being -- adding to our -- to begin adding to our financial performance starting in the fourth quarter. Although we have just completed this acquisition, we are still focused on identifying and acquiring additional products and technology that implement -- that complements our existing portfolio. As a reminder, we are targeting smaller bolt-on acquisitions that are around $25 million and continue to be actively engaged in evaluating potential acquisitions. There is still another 50% excess capacity to be leveraged as we anticipate generating more cash from the increased revenues combined with additional borrowing capacity. We will have more than sufficient resources to continue to implement our strategy. Mike will walk you through more on license and asset acquisition.
In addition, to the progress achieved on our short-term objectives, we also continue to invest in our long-term vision. Our primary competitive advantage is in cockpit automation where we have already introduced many new technologies that reduce pilot workload and Excellerate safety, most recently our autothrottle programs. This is a stepping stone to a reduction in the number of pilots in the aircraft. It is an area where we have significant intellectual property and intimate knowledge.
Consequently, we have been increasing our research and development budget to leverage this competitive advantage and as shown by increase in our R&D spending have recently been adding new engineers for this explicit purpose. Our research and development expenses may further increase in future quarters. However, this is a long-term program, and we believe we are responsibly managing the balance, which means investing for the long term while delivering attractive returns for our shareholders in the near term. We are excited by the success we've achieved so far this year, growing organically, completing an accretive acquisition, investing for the future while continuing to consistently deliver quarter after quarter of strong earnings. For over 30 years, we've built a reputation through the industry for developing some of the industry's most compelling flat price for performance products. This remains our formula for success. Thank you for your time and interest, and we look forward to updating you in the upcoming quarters.
Now I will turn the call over to Mike for a closer look at the numbers.

Michael Linacre

Thank you, Shahram, and thank you all for joining us today. I will review our financial results for the third quarter of fiscal 2023. Revenue growth in the third quarter was 15%, an acceleration relative to the second quarter revenue growth. This quarter, we once again generated revenues from both our stable OEM production contracts, which offer a solid base of predictable recurring revenue as well as an increase in aftermarket sales. Revenue was also well diversified among our target commercial air transport business and military markets. In particular, we saw new orders from the air cargo market for commercial air transfer Boeing 757 and 767's flat panel display conversions, an increase at our production military contract and strong autothrottle installations revenue, which is a new business this year.
The company completed an acquisition of several Honeywell product lines on June 30, 2023. The company did not recognize any revenues and net income related to those product lines in the third quarter of 2023. Keep in mind that both quarterly financial performance and new bookings are subject to variation in the timing of purchase orders, especially with our aftermarket products. On average, 40% of our revenues are from aftermarket sales. Consequently, as a management team, we evaluate our performance on an annualized basis, and we encourage our investors to do the same.
Third quarter gross margin was 59.5% compared to 58.5% in the third quarter a year ago. This improvement in gross margin reflects better absorption of our fixed overhead as a result of revenue growth, a favorable product mix, somewhat offset by a slight increase in direct material costs. Overall, for the year, margins continued to trend in line with historical averages with any fluctuation from quarter-to-quarter, primarily attributable to product mix as well as leveraging of our fixed manufacturing costs achieved through revenue growth. We don't anticipate the addition of the Honeywell product lines to have a material effect on future margins.
Operating profit in the current quarter was $1.4 million or 17.9% of sales, down on a relative basis from both the year ago and prior quarter, primarily due to a step up in general and administrative, research and development expenses. This quarter, SG&A again includes noncash stock-based long-term incentive compensation as well as a few onetime items associated with the closing of the Honeywell acquisition, including expenses for commissions and legal costs related to our new bank term loan.
In the fourth quarter, overhead will include the legal, accounting, audit, professional and other onetime expenses associated with the Honeywell product line acquisition. At the same time, any of the onetime items that impacted the last few quarters, such as the immediate vesting of noncash long-term incentive compensation awards have been recognized and will not impact future quarters. Our goal is to decrease our overhead run rate to approximately 20% over time, which will be aided by the increase in revenues from the Honeywell acquisition that entails little incremental overhead as well as the absence of the many onetime items over the past few quarters.
We continue to fund research and development at a higher level than a year ago as we work on our long-term vision this quarter, having added several new engineers dedicated to this program. We still expect to spend 13% of our revenue on R&D by the end of the year. Interest income was up in the quarter due to an increase of interest rates on our interest-bearing cash accounts. We do expect this to come down as cash balances will be lower as a result of the Honeywell acquisition.
Tax expense in the third quarter of fiscal 2023 was $0.4 million compared to the same amount in the third quarter of fiscal 2022. Third quarter net income was $1.4 million or $0.08 per diluted share, in line with the $1.4 million and $0.08 per diluted share we achieved in the third quarter of fiscal 2022. Backlog as of June 30, 2023, was $13.8 million and new orders in the third quarter of fiscal 2023 were approximately $6.9 million. This is a bit of a step down from the previous quarter when orders benefited from some pull forward as customers lock in orders for a longer term.
As always, quarterly orders can vary due to a number of factors and are not meant to provide an indicator of future revenues. Virtually all of the Honeywell revenues are from primarily intra-quarter book and ship orders. Cash on hand on June 30, 2023, was $2.6 million after utilizing approximately $16 million in the quarter for the acquisition of the Honeywell product lines. In the fiscal third quarter, to further strengthen our financial position and provide additional liquidity, we secured a $20 million term loan. IS&S was able to maintain a strong financial condition with sufficient cash on hand to run the operations of the business with ample liquidity with access to increased borrowing capacity.
Let me quickly review the Honeywell acquisition. The purchase price was $36 million, which included inventory valued at approximately $10 million, equipment value of approximately $4 million with the balance categorized as intangibles. These have been added to our balance sheet as of June 30, 2023. The purchase was paid in part with $16 million of our cash with the remainder borrowed under the new term loan I just mentioned. In addition to financing the acquisition, the term loan provides additional liquidity for ongoing operations and potential future acquisitions. While we expect cash flow from both our existing and acquired operations to enable us to quickly produce our borrowings, we nevertheless do expect annual interest expense to be in the range of approximately $1.6 million for the fiscal 2024.
These product lines have attractive margin profile characteristics that are similar to our current product portfolio, which is an essential element of our strategy. Consequently, once they've been integrated into our operations in 2024, we expect the transaction to materially contribute to our revenues and EBITDA. Revenues are expected to grow over 40%, while EBITDA is expected to grow roughly 75%. We also expect the resulting EPS to be accretive in fiscal 2024 with potential for additional net income increases in future years from various synergies. For the remainder of fiscal 2023, we're anticipating generating strong cash flows with similar or higher gross margin levels as capacity utilization and operating leverage expand against backdrop of revenue growth from organic and inorganic opportunities.
With that, operator, we'd like to open it up for any questions anyone has.

Question and Answer Session


(Operator Instructions) First question will be from Tim Moore, EF Hutton.

Timothy M. Moore

Congratulations on the strong impressive organic sales growth in the quarter in your core business. And Mike, thanks for the color on the September quarter commentary, that's appreciated. Maybe, Shahram, I got a question for you. Is there any update on the UMS? I know you gave comments on the King Air autothrottle progress and the great progress of flat display panels for air cargo, but just wondering if there's any update on UMS or even more ThrustSense autothrottle incoming inquiries or interest by new possible customers or them trying it out?

Shahram Askarpour

Sure. Yes. I mean the UMS is a long-term program. We're actually in the process of developing the next generation of that product line in partnership with Pilatus. With regards to autothrottle, we're looking at additional platforms, actually, some of them in the regional airline market that we are in current conversations, but pretty preliminary with regards to the kind of the market that we're in on the King Air side, we're expanding our sales activities internationally and we're seeing good interest coming from organizations across the world on the King Air platforms. Obviously, as more and more aircraft is produced by Textron and with our autothrottle in it, some of these customers who already have existing fleets, they look into upgrading their existing aircraft to bring them in line with the new aircraft that they're taking delivery out. So the prospects look promising.

Timothy M. Moore

Great. That's very helpful insights and details. And just related to that, you started to touch on it maybe with King Air going nationally, but can you maybe talk a little bit about the change or the enhancement in business development opportunities, innovative solutions, I recall maybe you added a VP of sales about a year ago, and it sounds like there's some really good development opportunities to cross-sell with Honeywell and penetrate both of your sides better. Is there any kind of progress or tactics you're thinking about for that?

Shahram Askarpour

Yes. I mean we just added another VP of technical sales as well to our business development activities to increase, obviously, with the acquisition of the product lines from Honeywell we need to strengthen our sales force. A lot of international sales are going to result from the Honeywell acquisition. So we've hired the sales guy full-time in the Australia, New Zealand area that would also support some of our Southeast Asia region. We're also looking at strengthening our partnership in Europe. And we're in conversations, actually, our new VP of sales is actually in Europe this week to talk about partnerships as well as sort of finding a place where we would maybe inventory, some equipment in Europe to support these new product lines that we acquired. So we're busy growing our sales and marketing group as well as customer service and customer support group, it's exciting times for us.

Timothy M. Moore

Well, that's a great update [really] that added color on the sales and technical team development build out. I mean you have such a good opportunity set, and I am glad you're investing in the proper hiring. Just a quick question. Your core business from what I recall, and Mike mentioned this pre-acquisition, Honeywell and pre-license was about 40% aftermarket. What will the pro forma mix be? Is Honeywell a bit more book and ship? Is it higher in aftermarket? Do you think the company's overall mix will be about 50% in the aftermarket.

Shahram Askarpour

Yes. But we've also been -- we're also busy with OEMs to get new OEM content. We certainly got another OEM program, which we haven't been able to announce yet because the aircraft hasn't been announced. So -- but that's about a year out in terms of production revenues. But I like the mixture of 40-40-20 is good because, obviously, on the aftermarket, margins are better than OEM. So we will rebuild the OEM side of it to get us to back to 40-40-20. The -- and through maybe the next acquisition that we do, we'll have some more OEM content on it. And that would help as well.

Timothy M. Moore

That's interesting. And looking forward to that next OEM award announcement, the aircraft gets announced in. My last question is, I know this is probably not a fair question. I realize it's only 6 weeks into the acquisition of the -- some Honeywell products and the license deal. But given that the team get there very quickly, I think they were there the first week of July, and that their experience from the heritage that they have with the Honeywell lines, how is integration going and the progress with the new team? Just kind of curious about that.

Shahram Askarpour

Actually, it's progressing well according to our plan. So we've been fortunate that the team at Honeywell have been very cooperative. We have a very good relationship with them. They have been very supportive of this. Obviously, they want this to be successful. Again, this acquisition wasn't about the highest bidder, was about who is actually going to be able to work well with Honeywell and their customers to have a successful transition. And we were chosen based on that. And everything is progressing well and we continue executing it.


(Operator Instructions) At this time we have no further questions. The conference has now concluded. Thank you for attending today's presentation. You may now disconnect.

Killexams : Are You a Terrible Writer? ChatGPT Can Help, Study Finds

AI has gotten a lot of attention lately, especially services like ChatGPT, which can be used for everything from finding a good recipe to writing a blog post. A new study shows that it also might be a powerful tool in helping bad writers Excellerate their skills.

In a study published this week in Science, two MIT researchers examined whether ChatGPT could be used to reduce gaps in writing ability between employees. The duo recruited 453 data analysts, marketers, and college-educated professionals and asked them to perform two different writing tasks normally associated with their jobs—writing press releases or a short report, for instance.

Half of the participants were given the option of using ChapGPT to help them complete the second of the two tasks. Afterward, their work was graded by other professionals who worked in the same field on a scale of one to seven, with seven being the best result.

Overall, the participants who used ChatGPT did better than those who didn’t. ChatGPT users took 40% less time to complete their task than their counterparts, and their completed work scored 18% higher in evaluations than the work of those who didn’t use it.

The researchers note that while ChatGPT is powerful, it can also introduce errors, so people who use it to write for them will need to double-check that everything written by the AI tool is correct.

That said, the workers who participated in the study said they were more likely to use the tool in the future. "Workers exposed to ChatGPT during the experiment were 2 times as likely to report using it in their real job 2 weeks after the experiment and 1.6 times as likely 2 months after the experiment," the study found.

Killexams : Blue-light glasses don’t help with eye strain, major study says

Editor’s Note: Get inspired by a weekly roundup on living well, made simple. Sign up for CNN’s Life, But Better newsletter for information and tools designed to Excellerate your well-being.

CNN  — 

Adding a blue-light filter to your eyeglasses may not ease eye strain from computer work, protect the retina or help with sleep at night, according to a new review of existing research.

“We found there may be no short-term advantages with using blue-light filtering spectacle lenses to reduce visual fatigue associated with computer use,” said senior author Laura Downie in a statement. Downie is an associate professor of optometry and vision sciences and director of the anterior eye, clinical trials and research translation unit at the University of Melbourne in Victoria, Australia.

“It is also currently unclear whether these lenses affect vision quality or sleep-related outcomes, and no conclusions could be drawn about any potential effects on retinal health in the longer term,” Downie said. “People should be aware of these findings when deciding whether to purchase these spectacles.”

In reality, it’s not the blue-light emission from our devices that is causing eye strain for most people, said ophthalmologist Dr. Craig See, a cornea specialist at Cole Eye Institute at the Cleveland Clinic in Ohio.

“Most people have computer vision syndrome, which is related to sitting at a computer screen for a long period of time,” said See, who was not involved in the study.

Symptoms of computer vision syndrome include dry eyes, watery eyes, blurry vision, light sensitivity, burning or itchy eyes, and difficulty concentrating and keeping your eyes open, according to the Cleveland Clinic. Eye strain from presbyopia, which is the gradual loss with age of the ability of the eye to focus on nearby objects, can contribute, as can neck and shoulder pain, See said.

“I don’t typically recommend blue-light filters to my patients,” See said. “There’s no reason to think that blue-light filtering is harmful, other than the cost associated with adding it to your glasses. The takeaway here is that it may not be doing as much as we were hoping.”

The report, published Thursday in the Cochrane Database of Systematic Reviews, analyzed data from 17 randomized controlled clinical trials conducted in six countries that lasted from a few days to a few months. The review is part of the nonprofit Cochrane Collaboration, an independent, international network of researchers that uses some of the highest standards in evidence-based research.

The brevity of the clinical trials affected the reviewers’ ability to consider longer-term outcomes, Downie said. “Our certainty in the reported findings should be interpreted in the context of the quality of the available evidence.”

In addition, blue-light filtering lenses only filter between 10% and 25% of blue light from artificial devices such as computer screens, and that blue light is only “a thousandth of what we get from natural daylight,” said first author Dr. Sumeer Singh, a postdoctoral clinical research fellow in the anterior eye, clinical trials and research translation unit at the University of Melbourne.

“Filtering out higher levels of blue light would require the lenses to have an obvious amber tint, which would have a substantial effect on colour perception,” he said in a statement.

The review was conducted to answer an ongoing debate on whether blue-light filtering lenses have any merit in ophthalmic practice, Downie said.

“Research has shown that these lenses are frequently prescribed to patients in many parts of the world, and a range of marketing claims exist about their potential benefits, including that they may reduce eye strain associated with digital device use, Excellerate sleep quality and protect the retina from light-induced damage,” she said.

“Our findings do not support the prescription of blue-light filtering lenses to the general population,” Downie said. “These results are relevant to a broad range of stakeholders, including eye care professionals, patients, researchers and the broader community.”

There are a number of actions you can take to ease or prevent eye strain, See said. First, if you haven’t had your eyes checked in the last year or two, visit a specialist right away. Your eyes may have weakened, making a new prescription necessary.

“When you visit the eye doctor, go in with a measurement of how far away your face is from your computer screen, so the doctor can maximize your prescription,” See said. “You should be arm’s length from the screen. And if you’re using a laptop, consider getting a larger external display that you can plug into.”

Having a bigger screen can ease eye strain by increasing text size and may also reduce headaches and neck strain from bending over the laptop, See explained.

“If your text is difficult for you to read, it’s going to take you longer to read it,” he said. “You will be affecting your posture to do so, and you’ll be blinking even less if you’re straining to read things. Having a bigger screen can help with that.”

The eye stops blinking regularly as computer time increases, See said, so taking regular breaks from work at the computer is also important. Try using the 20-20-20 rule — every 20 minutes, look at something 20 feet (6 meters) away for 20 seconds, which can encourage your eyes to blink at their normal rate. Better yet, get up and walk away, because constant sitting will increase neck and back strain.

If dry eyes are part of the problem, a warm compress applied to your eyes can offer relief, as can over-the-counter artificial tears. But keep the use to a minimum – many contain preservatives and should be used no more than four times a day.

“If you need them more often, you need to move to preservative-free tears, which come in a vial,” See said. “I will say if you need artificial teardrops more than four times a day, then I think it’s a good idea to see an eye doctor for your condition.”
