Published Scientists deliver quantum algorithm to develop new materials and chemistry
(via sciencedaily.com) Original source Scientists published the Cascaded Variational Quantum Eigensolver (CVQE) algorithm in a recent article, expected to become a powerful tool to investigate the physical properties in electronic systems.
Published 'Winners and losers' as global warming forces plants uphill
(via sciencedaily.com) Original source Some plant species will 'win' and others will 'lose' as global warming forces them to move uphill, new research shows.
Published The world is one step closer to secure quantum communication on a global scale
(via sciencedaily.com) Original source Researchers have brought together two Nobel prize-winning research concepts to advance the field of quantum communication. Scientists can now efficiently produce nearly perfect entangled photon pairs from quantum dot sources.
Published Novel quantum algorithm for high-quality solutions to combinatorial optimization problems
(via sciencedaily.com) Original source Conventional quantum algorithms are not feasible for solving combinatorial optimization problems (COPs) with constraints in the operation time of quantum computers. To address this issue, researchers have developed a novel algorithm called post-processing variationally scheduled quantum algorithm. The novelty of this innovative algorithm lies in the use of a post-processing technique combined with variational scheduling to achieve high-quality solutions to COPs in a short time.
Published Semiconductors at scale: New processor achieves remarkable speed-up in problem solving
(via sciencedaily.com) Original source Annealing processors are crucial for solving combinatorial optimization problems. However, they face scalability challenges due to the complexity of required architecture. TUS researchers have now designed a scalable, fully-coupled processor with 4096 spins and parallel processing capabilities. It demonstrates superior performance and power efficiency compared to traditional devices. The research team aims to develop a 2050-level quantum computer computing system by 2030, potentially revolutionizing digital industries without relying on extensive infrastructure or cloud support.
Published Physicists develop modeling software to diagnose serious diseases
(via sciencedaily.com) Original source Researchers have recently published FreeDTS -- a shared software package designed to model and study biological membranes at the mesoscale -- the scale 'in between' the larger macro level and smaller micro level. This software fills an important missing software among the available biomolecular modeling tools and enables modeling and understanding of many different biological processes involving the cellular membranes e.g. cell division.
Published N-channel diamond field-effect transistor
(via sciencedaily.com) Original source A research team has developed an n-channel diamond MOSFET (metal-oxide-semiconductor field-effect transistor). The developed n-channel diamond MOSFET provides a key step toward CMOS (complementary metal-oxide-semiconductor: one of the most popular technologies in the computer chip) integrated circuits for harsh-environment- applications as well as the development of diamond power electronics.
Published Species diversity promotes ecosystem stability
(via sciencedaily.com) Original source What maintains stability within an ecosystem and prevents a single best competitor from displacing other species from a community? Does ecosystem stability depend upon the presence of a wide variety of species, as early ecologists believed, or does diversity do the exact opposite, and lead to instability, as modern theory predicts? A new study suggests an answer to this question that has been a subject of debate among ecologists for half a century.
Published Forest, stream habitats keep energy exchanges in balance, global team finds
(via sciencedaily.com) Original source Forests and streams are separate but linked ecosystems, existing side by side, with energy and nutrients crossing their porous borders and flowing back and forth between them. For example, leaves fall from trees, enter streams, decay and feed aquatic insects. Those insects emerge from the waters and are eaten by birds and bats. An international team has now found that these ecosystems appear to keep the energy exchanges in balance -- a finding that the scientists called surprising.
Published AI can now detect COVID-19 in lung ultrasound images
(via sciencedaily.com) Original source Artificial intelligence can spot COVID-19 in lung ultrasound images much like facial recognition software can spot a face in a crowd, new research shows. The findings boost AI-driven medical diagnostics and bring health care professionals closer to being able to quickly diagnose patients with COVID-19 and other pulmonary diseases with algorithms that comb through ultrasound images to identify signs of disease.
Published Scientists weigh up current status of blue whale populations around the world
(via sciencedaily.com) Original source The largest living animal, the blue whale (Balaenoptera musculus) which averages about 27 meters in length, has slowly recovered from whaling only to face the rising challenges of global warming, pollution, disrupted food sources, shipping, and other human threats. In a major new study, biologists have taken a stock of the number, distribution and genetic characteristics of blue whale populations around the world and found the greatest differences among the eastern Pacific, Antarctic subspecies and pygmy subspecies of the eastern Indian and western Pacific.
Published Verifying the work of quantum computers
(via sciencedaily.com) Original source Researchers have invented a new method by which classical computers can measure the error rates of quantum machines without having to fully simulate them.
Published Quantum talk with magnetic disks
(via sciencedaily.com) Original source Quantum computers promise to tackle some of the most challenging problems facing humanity today. While much attention has been directed towards the computation of quantum information, the transduction of information within quantum networks is equally crucial in materializing the potential of this new technology. Addressing this need, a research team is now introducing a new approach for transducing quantum information: the team has manipulated quantum bits, so called qubits, by harnessing the magnetic field of magnons -- wave-like excitations in a magnetic material -- that occur within microscopic magnetic disks.
Published Monitoring and measuring biodiversity require more than just numbers; scientists advocate for change
(via sciencedaily.com) Original source Scientists advocate for change to promote standardized practices in the field -- a practice that has been missing from the science.
Published Researchers investigate how freshwater diatoms stay in the light
(via sciencedaily.com) Original source Researchers sought to understand how diatoms -- microscopic, photosynthetic algae that make up an estimated 20 percent of global carbon sequestration and oxygen production -- are able to bloom in an ice-covered Lake Erie and how ice decline across the Great Lakes is impacting the algae.
Published AI ethics are ignoring children, say researchers
(via sciencedaily.com) Original source Researchers have called for a more considered approach when embedding ethical principles in the development and governance of AI for children.
Published Powerful new AI can predict people's attitudes to vaccines
(via sciencedaily.com) Original source A powerful new tool in artificial intelligence is able to predict whether someone is willing to be vaccinated against COVID-19.
Published Brain-inspired wireless system to gather data from salt-sized sensors
(via sciencedaily.com) Original source In a new study, researchers describe a novel approach for a wireless communication network that can efficiently transmit, receive and decode data from thousands of microelectronic chips that are each no larger than a grain of salt.
Published Artificial nanofluidic synapses can store computational memory
(via sciencedaily.com) Original source In a step toward nanofluidic-based neuromorphic -- or brain-inspired -- computing, engineers have succeeded in executing a logic operation by connecting two chips that use ions, rather than electrons, to process data.
