| Innovative AI technology aids personalized care for diabetes patients needing complex drug treatment Posted: 25 Mar 2022 09:24 AM PDT Medical researchers have developed and tested an AI method to improve care for patients with type 2 diabetes mellitus who need complex treatment. The new AI method analyzed electronic health record data across Utah and Indiana and learned generalizable treatment patterns of type 2 diabetes patients with similar characteristics. Those patterns can now be used to help determine an optimal drug regimen for a specific patient. |
| Quantum physics sets a speed limit to electronics Posted: 25 Mar 2022 06:39 AM PDT Semiconductor electronics is getting faster and faster - but at some point, physics no longer permits any increase. The speed can definitely not be increased beyond one petahertz (one million gigahertz), even if the material is excited in an optimal way with laser pulses. |
| Simply printing high-performance perovskite-based transistors Posted: 25 Mar 2022 06:39 AM PDT A research team develops high performing p-type transistor using perovskite. Solution-processed metal halide perovskite transistors can now be printed. |
| 'Hot' spin quantum bits in silicon transistors Posted: 25 Mar 2022 06:38 AM PDT Quantum bits (qubits) are the smallest units of information in a quantum computer. Currently, one of the biggest challenges in developing this kind of powerful computer is scalability. A research group has now made a breakthrough in this area. |
| Scientists shave ‘hairs’ off nanocrystals to improve their electronic properties Posted: 24 Mar 2022 03:46 PM PDT A new study introduces a breakthrough in making nanocrystals function together electronically. The research may open the doors to future devices with new abilities. |
| New Fermi arcs could provide a new path for electronics Posted: 24 Mar 2022 03:46 PM PDT Newly discovered Fermi arcs that can be controlled through magnetism could be the future of electronics based on electron spins. During a recent investigation of the rare-earth monopnictide NdBi (neodymium-bismuth), researchers discovered a new type of Fermi arc that appeared at low temperatures when the material became antiferromagnetic, i.e., neighboring spins point in opposite directions. |
| Artificial neurons go quantum with photonic circuits Posted: 24 Mar 2022 09:25 AM PDT In recent years, artificial intelligence has become ubiquitous, with applications such as speech interpretation, image recognition, medical diagnosis, and many more. At the same time, quantum technology has been proven capable of computational power well beyond the reach of even the world's largest supercomputer. Physicists have now demonstrated a new device, called quantum memristor, which may allow to combine these two worlds, thus unlocking unprecedented capabilities. The experiment has been realized on an integrated quantum processor operating on single photons. |
| Photonic technology enables real-time calculation of radio signal correlation Posted: 24 Mar 2022 07:45 AM PDT Researchers have developed a new analog photonic correlator that can be used to locate an object transmitting a radio signal. They demonstrated its ability to identify the location of a radio frequency transmitter, working faster than other methods. The device is considerably simpler than today's analog or digital correlators and uses off-the-shelf telecommunications components to process a wide range of radio frequency signals in cell phones, signal jammers, and more. |
| Immune to hacks: Inoculating deep neural networks to thwart attacks Posted: 24 Mar 2022 07:45 AM PDT If a sticker on a banana can make it show up as a toaster, how might strategic vandalism warp how an autonomous vehicle perceives a stop sign? Now, an immune-inspired defense system for neural networks can ward off such attacks, designed by engineers, biologists and mathematicians. |
