LOS ALAMOS, N.M., Aug. 15, 2023 — A potentially game-changing theoretical approach to quantum computing hardware avoids much of the problematic complexity found in current quantum computers. The strategy implements an algorithm in natural quantum interactions to process a variety of real-world problems faster than classical computers or conventional gate-based quantum computers can.

“Our finding eliminates many challenging requirements for quantum hardware,” said Nikolai Sinitsyn, a theoretical physicist at Los Alamos National Laboratory. He is coauthor of a paper on the approach in the journal Physical Review A. “Natural systems, such as the electronic spins of defects in diamond, have precisely the type of interactions needed for our computation process.”

Sinitsyn said the team hopes to collaborate with experimental physicists also at Los Alamos to demonstrate their approach using ultracold atoms. Modern technologies in ultracold atoms are sufficiently advanced to demonstrate such computations with about 40 to 60 qubits, he said, which is enough to solve many problems not currently accessible by classical, or binary, computation. A qubit is the basic unit of quantum information, analogous to a bit in familiar classical computing.

Longer-lived qubits

Instead of setting up a complex system of logic gates among a number of qubits that must all share quantum entanglement, the new strategy uses a simple magnetic field to rotate the qubits, such as the spins of electrons, in a natural system. The precise evolution of the spin states is all that is needed to implement the algorithm. Sinitsyn said the approach could be used to solve many practical problems proposed for quantum computers.

Quantum computing remains a nascent field handicapped by the difficulty of connecting qubits in long strings of logic gates and maintaining the quantum entanglement required for computation. Entanglement breaks down in a process known as decoherence, as the entangled qubits begin to interact with the world outside the quantum system of the computer, introducing errors. That happens quickly, limiting the computation time. True error correction has not yet been implemented on quantum hardware.

The new approach relies on natural rather than induced entanglement, so it requires fewer connections among qubits. That reduces the impact of decoherence. Thus, the qubits live for a relatively a long time, Sinitsyn said.  

The Los Alamos team’s theoretical paper showed how the approach could solve a number-partitioning problem using Grover’s algorithm faster than existing quantum computers. As one of the best-known quantum algorithms, it allows unstructured searches of large data sets that gobble up conventional computing resources. For instance, Sinitsyn said, Grover’s algorithm can be used to divvy up the runtime for tasks equally between two computers, so they finish at the same time, along with other practical jobs. The algorithm is well-suited to idealized, error-corrected quantum computers, although it is difficult to implement on today’s error-prone machines.

Protected against errors

Quantum computers are built to perform computations much faster than any classical device can do, but they have been extremely hard to realize so far, Sinitsyn said. A conventional quantum computer implements quantum circuits — sequences of elementary operations with different pairs of qubits.

The Los Alamos theorists proposed an intriguing alternative.

“We noticed that for many famous computational problems it is sufficient to have a quantum system with elementary interactions, in which only a single quantum spin — realizable with two qubits — interacts with the rest of the computational qubits,” Sinitsyn said. “Then a single magnetic pulse that acts only on the central spin implements the most complex part of the quantum Grover’s algorithm.” Called the Grover’s oracle, this quantum operation points to the desired solution.

“No direct interactions between the computational qubits and no time-dependent interactions with the central spin are needed in the process,” he said. Once the static couplings between the central spin and qubits are set, the entire computation consists only of applying simple time-dependent external field pulses that rotate the spins, he said.

 Importantly, the team proved that such operations can be made fast. The team also discovered that their approach is topologically protected. That is, it is robust against many errors in the precision of the control fields and other physical parameters even without quantum error correction.

Killexams : Research team describes novel approach to bilingual speech therapy

It's a difficult, impressive feat on its own to help children work through speech problems. It's even more inspiring when you take into account the bridge of language itself.

That's a path just crossed by UNM Speech & Hearing Sciences Assistant Professor Carlos Irizarry-Pérez, in his newly published research, titled "A Complexity Approach to Promoting Within- and Cross-Language Generalization in Bilingual Children With Phonological Delays."

The work is published in the journal Language, Speech, and Hearing Services in Schools.

"Generalization is taking a skill that you've learned in one particular context and being able to use it in another context. Best practice is to approach generalization from the most complex aspects of with the belief that the simpler pieces fall in place," Irizarry-Pérez said.

This was part of a massive undertaking. Phonological delays, the inability to fully and correctly form the sound system of a , is a predictable and therefore treatable speech disorder. Irizarry-Pérez found a new way to do so.

"Speech sound disorders, which can look a lot of different ways, but in really simple terms, are difficulty with producing sounds accurately," he said. "With , there's more than one language, so it's harder, and there just hasn't been a lot done in that area for bilingual children."

Whether it's missing a certain sound, or replacing one sound with another, the causeless condition is a difficult one when working with bilingual children. It's even more challenging, given the lack of bilingual speech therapists working—a startlingly low 8%.

"We don't have a lot of bilingual therapists. So how do we address this need for children that are bilingual and have these disorders? We kind of have to be creative in how we do that," Irizarry-Pérez said.

"Try to be the most efficient about things; that's the strategy I at least recommend that clinicians take. You can always find the pieces within languages that are complex. Then find the pieces that overlap with English. That is really the novel piece we were testing and that I think is applicable to most bilingual children and their clinicians."

Irizarry-Pérez's unique approach focused on choosing complex sounds, consonant clusters, similar to both languages and integrating those sounds into children's sound systems for them to generalize.

"If we also choose sounds that are harder for the child, they will have the least amount of information, so we'll get even more generalization within the child's sound system. This is really important for children that have difficulty organizing sounds in their sound system," he said.

Once that sound gets acquired in one language, then the concept of generalization should get the child to acquire similar sounds in the other language.

"When we choose sounds as intervention targets, they're the same or very similar, at least across the child's languages, so those skills generalize," Irizarry-Pérez said. "If we can get a child to be accurate with those sounds, either of the languages will typically generalize into the other with intervention."

It's different from many other processes, which escalate from simple, single sounds to piecing harder sounds together one by one.

"We took shared sounds, complex clusters that were shared across Spanish and English, and provided intervention in just Spanish. We looked for the generalization of the skills to be able to produce that cluster in both languages," Irizarry-Pérez said.

For a year, a handful of 4 to 7-year-olds practiced weekly in one-hour sessions. They were guided tirelessly by Clinical Instructor Andrea Martinez-Fischer and their dedicated graduate students.

"It was really interesting to watch the students grow from being brand new clinicians to being able to independently scaffold and support their clients," she said. "It is difficult to find speech therapy done in Spanish, so this work with bilingual graduate clinicians is so important not only for them and their training but also for putting out research that informs our bilingual practice as a whole."

Not only did the children themselves come out of this process with notable speech improvement, but parents earned new tools with immense gratitude.

"They all expressed gratitude and happiness just for the fact that we were considering both of the child's languages and their experiences," Irizarry-Pérez said. "These children come home in most cases to bilingual or Spanish-only environments, and the parents and children need to communicate and understand each other as well."

The marked success is just one piece of the puzzle involving phonological delays, but Irizarry-Pérez and Martinez-Fischer believe speech therapists across the country can learn something from this.

"In a minority-majority state like NM, services delivered in a child's native/home language should be accessible and is best practice," Martinez-Fischer said. "The research completed, and training of our graduate students assists in making the services provided to our Spanish-speaking population evidence-based and appropriate for the people we serve. "

It could even help fill the current gap of bilingual speech therapists. On top of training UNM graduate students early on, if this research gains steam, it could inspire positive interventions for speech therapists hesitant to take the extra step.

"Any time I think that a therapist has a bilingual child on their caseload that has difficulty with phonology, speech sounds, and falls within that kind of age range and characteristics, the approach we were testing does work. That is to choose sounds first that are shared and that are complex," Irizarry-Pérez said.

This theory is something he hopes to eventually apply to additional language pairs beyond Spanish and English.

"We know that these language systems are connected through interdependence. There are aspects as well that are shared across languages. It's just a matter of whether those complex sounds and the sounds that are shared overlap enough to take this approach," Irizarry-Pérez said.

Killexams : Novel therapeutic approach against severe COVID-19 in males

Retrospective analyses of epidemiologic data have repeatedly shown that COVID-19 mortality is higher in males compared to females. However, the underlying factors mediating sex-specific disease outcome were largely unknown.

In a new study published in Cell Reports Medicine, an interdisciplinary research team analyzed obtained from 2,866 COVID-19 patients and identified a mutation in the CYP19A1 gene that is associated with an increased risk for hospitalization in male patients. CYP19A1 plays a key role in testosterone metabolism. Lung samples analyzed from deceased COVID-19 patients also showed increased expression of the CYP19A1 gene in male patients compared to female patients. These findings suggest that this gene is involved in sex-differences observed in COVID-19 outcomes.

"This collaborative work stresses the importance of host genetics in understanding molecular mechanisms of severity and treatment of viral disorders," says Professor Alessandra Renieri of the University of Siena who provided the genetic data of the large COVID-19 cohort.

Preclinical studies in animal models confirmed these findings. Treatment of SARS-CoV-2-infected animals with the aromatase inhibitor letrozole improved long-term lung function and restored hormonal balance, particularly in male animals. This suggests that may provide a promising therapeutic strategy for the treatment of male COVID-19 patients.

Professor Gülşah Gabriel confirms the importance of international and and highlights, "Our collaborative findings may form a basis for individualized therapeutic strategies against COVID-19."

Killexams : Novel approach to identify silver shortages in PV industry

A Dutch-German research team has used a unique method to detect silver shortages in the PV industry. By mapping the silver supply chain from 1995 to 2021, they have identified distinct supply patterns and associated risks.

Researchers at Germany's Fraunhofer Institute for Solar Energy (Fraunhofer ISE) and the Institute of Environmental Sciences (CML) in the Netherlands have conducted risk-based due diligence on the silver supply for the PV industry, in order to identify possible shortages in the future.

“Considering the current typical lead times of the mining industry and the constraints such as permitting and environmental, social, and governance (ESG) issues linked to mine expansion, it is clear that material bottlenecks of unknown duration are in the cards,” researcher Estelle Gervais told pv magazine. “Supply disruptions can therefore be expected for silver, as they can be expected for numerous other materials required in energy technologies, including copper.”

She said that the silver industry has historically been resilient to these challenges because of strategic stocks and recycling, which have played key roles during periods of undersupply over the last 50 years. Silver reserves have also not significantly decreased relative to production over time, which suggests that exhausted reserves have been replenished through mine expansion.

“This is at least a cautiously optimistic sign for the medium to long-term,” said Gervais. “Estimates of future supply are linked to high uncertainty. We could, however, identify concrete risks related to market concentration and ESG issues in silver supply chains, which could translate into supply constraints in the short term. This is especially true for PV markets like the EU and the USA, which are increasingly working towards supply security and sustainability.”

Gervais and her colleagues mapped the solar supply chain of silver from 1995 to 2021 and identified a series of supply patterns and risks. They also analyzed the impact of alternative supply routes and the reshoring PV manufacturing to Europe.

The research group said that most ESG risks from silver paste fabrication are in China, due to its market dominance. The researchers said Mexico and China account for most ESG risks in mining and refining. They also noted the need to prioritize due diligence and traceability with local players, as ESG risk monitoring becomes the norm.

“Reducing silver consumption in PV is crucial, both to alleviate the silver price pain point and reduce the environmental and social impacts along the supply chain,” Gervais said, in reference to the ability of PV producers to reduce silver content in solar cell production – a process referred to as thrifting. “Silver prices are however both a problem and part of the solution. They will play a role in bringing supply and demand into balance, and provide an incentive for PV recycling.”

Gervais said that prolongated periods of silver undersupply could be a clear deterrent for the PV industry and would intensify the focus on substitutes.

“Copper prices make it a great alternative to silver in PV and there have been considerable technological advances in this area,” Gervais added. “Copper contact paste development for screen printing is advancing and industrial manufacturing solutions for copper plating are available. It should nevertheless be underlined that switching from silver to copper will not automatically ensure PV manufacturers have a ‘sustainable' product. Not all copper is created equal: only a careful examination of the underlying copper supply chains and a diversified supply would support that.”

Gervais and her team presented their findings in “Risk-based due diligence in supply chains: The case of silver for photovoltaics,” which was recently published in Resources, Conservation and Recycling.

Killexams : Sound Waves Could Be A Novel Tactic in Battling Cocaine Addiction

Summary: Researchers are launching a pioneering study using low-intensity focused ultrasound to address cocaine addiction by targeting the insula region of the brain. This noninvasive technique aims to reprogram brain cells to diminish cocaine cravings.

If successful, this approach could revolutionize addiction treatment. The initiative springs from increasing cocaine use and related deaths in Virginia and a lack of FDA-approved treatments for the addiction.

Key Facts:

  1. The study will use focused ultrasound to target the insula, a part of the brain associated with various addictions.
  2. There are currently no FDA-approved medications specifically to help people quit cocaine.
  3. UVA’s investigation on focused ultrasound has previously led to FDA approval for treatments related to Parkinson’s symptoms and essential tremor.

Pioneering researchers at UVA Health are testing whether focused sound waves can help people overcome cocaine addiction, a growing problem across the nation.

The scientists have launched a clinical trial, believed to be the first of its kind in the world, to test whether low-intensity focused ultrasound can help reprogram brain cells to reduce the desire for cocaine.

This shows a brain and sound waves.

The noninvasive approach focuses sound waves on a portion of the brain called the insula, thought to play a critical role in multiple forms of addiction. If the trial is successful, it could pave the way for an important new tool to treat addiction in general.

“This trial will inform us if focused ultrasound could change the way some patients feel about cocaine,” said principal investigator Nassima Ait-Daoud Tiouririne, MD, the director of UVA’s Center for Leading Edge Addiction Research (CLEAR). “What if we could reverse brain changes caused by drug use? This would change the way we treat addiction as a whole.”

Cocaine Addiction: A Growing Problem

Cocaine use has been increasing steadily in Virginia for a decade, the researchers note. Overdose deaths jumped by a third from 2019 to 2020 alone. Those troubling trends have the UVA scientists eager to find innovative ways to reduce people’s cravings for the highly addictive drug. There are currently no medications approved by the federal Food and Drug Administration that can help people quit.

In their new trial, the UVA researchers will use focused sound waves to gently massage cells within the insula. The scientists will then see if the approach causes chemical changes in the brain that reduce cocaine cravings. (Prior studies have already shown that the insula plays an important role in both cocaine cravings and relapse; further, the researchers note, humans who suffered injuries to the insula were able to quit smoking easily, without suffering cravings or relapse.)

If the approach proves safe and effective, patients might one day soon go for a simple outpatient visit and leave with less desire to use cocaine.

“If successful, we become one step closer to developing new, safer ways to treat addiction,” said Ait-Daoud Tiouririne, of UVA’s Department of Psychiatry and Neurobehavioral Sciences. “Addiction is brain disorder. Treatment should include noninvasive neuromodulation of the brain circuits that cause the addiction in the first place.”

UVA’s trial is recruiting people ages 18 or older who have been diagnosed with cocaine-use disorder and who are not trying to provide up using cocaine.

The trial has received $5 million in support from the National Institutes of Health’s National Institute on Drug Abuse, grant 1UG3DA054789-01A1.

Focused Ultrasound at UVA

The cocaine trial joins an expansive portfolio of research underway at the University of Virginia School of Medicine to explore the vast potential of focused ultrasound to treat serious diseases ranging from cancer to Alzheimer’s.

UVA has long been a world leader in pioneering applications of focused ultrasound that will benefit patients. Prior research led by UVA’s Jeff Elias, MD, and colleagues, for example, paved the way for the FDA to approve high-intensity focused ultrasound to treat both Parkinson’s symptoms and essential tremor, a common movement disorder.

The success of its focused ultrasound efforts prompted UVA Health last year to launch the world’s first center devoted specifically to combining focused ultrasound with immunotherapy to Improve cancer care. The researchers hope that the combination will open new fronts in the war against many different forms of cancer, from breast cancer to brain tumors. 

UVA’s game-changing research with focused ultrasound recently spurred CNN’s Sanjay Gupta, MD, to put together an in-depth story on one patient’s experience that was broadcast around the world.
