| Researchers investigate the links between facial recognition and Alzheimer's disease Posted: 31 May 2022 07:27 AM PDT In recent years Alzheimer's disease has been on the rise throughout the world and is rarely diagnosed at an early stage when it can still be effectively controlled. Using artificial intelligence, researchers conducted a study to identify whether human-computer interfaces could be adapted for people with memory impairments to recognize a visible object in front of them. |
| Multi-spin flips and a pathway to efficient ising machines Posted: 31 May 2022 07:26 AM PDT Combinatorial optimization problems are at the root of many industrial processes and solving them is key to a more sustainable and efficient future. Ising machines can solve certain combinatorial optimization problems, but their efficiency could be improved with multi-spin flips. Researchers have now tackled this difficult problem by developing a merge algorithm that disguises a multi-spin flip as a simpler, single-spin flip. This technology provides optimal solutions to hard computational problems in a shorter time. |
| A new arrangement: Using quantum dots to quench the smallest ferrimagnetism Posted: 31 May 2022 06:15 AM PDT A team of scientists have focused on the Kondo effect on minimal ferrimagnetism and attempted to elucidate it theoretically. As a result, they found that the Kondo effect occurred via multiple 'quantum entangled states' depending on temperature and other factors. They also found that the Kondo effect suppressed electrical conductivity through minimal ferrimagnetism, when usually it is amplified in many other cases. |
| Ultrasound-guided microbubbles boost immunotherapy efficacy Posted: 30 May 2022 09:04 AM PDT Researchers have developed an ultrasound-guided cancer immunotherapy platform that generates systemic antitumor immunity and improves the therapeutic efficacy of immune checkpoint blockade. |
| Electrode design paves way for better biofuel cells, electrochemical devices Posted: 24 May 2022 08:06 AM PDT Most biofuel cells provide low power output and short-term operational stability due to their poor electron transfer between enzymes and electrodes and between neighboring enzymes. These electron transfer issues are closely related to the performance of almost all electrochemical sensors, including BFCs and other bioelectronics. In a new paper, scientists address these shortcomings via an amphiphilic assembly designed to prepare high-performance biofuel cells. |
