Normally, it takes pricey equipment and expertise to create an accurate 3D reconstruction of someone's face. Now, Carnegie Mellon University researchers have pulled off the feat using video recorded on an ordinary smartphone. Shooting a continuous video of the front and sides of the face generates a dense cloud of data. A two-step process developed by CMU's Robotics Institute uses that data, with some help from deep learning algorithms, to build a digital reconstruction of the face.
A paper in the journal Physical Review Applied outlines a way to teach an AI to make an interconnected set of adjustments to the quantum dots that could form the qubits in a quantum computer's processor. Precisely tweaking the dots is crucial for transforming them into properly functioning qubits, and until now the job had to be done painstakingly by human operators, requiring hours of work to create even a small handful of qubits for a single calculation.
Researchers from the Quantum Optomechanics group at the Niels Bohr Institute, University of Copenhagen, recently entangled two laser beams through bouncing them off the same mechanical resonator, a tensioned membrane. This provides a novel way of entangling disparate electromagnetic fields, from microwave radiation to optical beams. Creating entanglement between optical and microwave fields would be a key step towards solving the challenge of sharing entanglement between two distant quantum computers operating in the microwave regime.
New 'CALM' model on passenger movement developed using Frontera supercomputer.
As circuit interconnects shrink to nanoscale, will the pressure caused by thermal expansion when current flows through wires cause gold to behave more like a liquid than a solid -- making nanoelectronics unreliable? Fortunately, research suggests that chip designers can continue to put their faith in gold.
Coronavirus envelope all-atom computer model being developed by Amaro Lab of UC San Diego on NSF-funded Frontera supercomputer of TACC at UT Austin. Coronavirus model builds on success of all-atom infuenza virus simulations by Amaro Lab. Molecular dynamics simulations for the coronavirus model tests ran on up to 4,000 nodes, or about 250,000 of Frontera's processing cores. Full model can help researchers design new drugs, vaccines to combat the coronavirus.
Researchers have engineered a novel type of supercapacitor that maintains full functionality even when stretched to eight times its original size. It does not exhibit any wear and tear from being stretched thousands of times, and loses only a few percentage points of energy performance after 10,000 cycles of charging-discharging. The researchers envision the supercapacitor being part of a power-independent, stretchable, flexible electronic system for applications such as wearable electronics or biomedical devices.
Researchers from Aalto University (Finland), UCLouvain (Belgium), and New York University (USA) have gathered extensive radar measurement data, aiming to improve the detection and identification of drones.
Supercomputer simulations support a new mechanism for the budding off of viruses like the coronavirus. ESCRTIII polymer features clear intrinsic twist in molecular dynamics simulations, might play major role in creating three-dimensional buckling of the cell membrane. Related study used simulations to find mechanism for DNA base addition during replication. XSEDE-allocated supercomputers Stampede2 of TACC and Comet of San Diego Supercomputer Center supported studies. Fundamental research could help combat infectious and genetic diseases.
Published today, during World Glaucoma Week 2020, a new study demonstrates how commercially available head mounted displays (HMD) can be used to simulate the day-to-day challenges faced by people with sight loss from glaucoma. The study, from the Crabb Lab, at City, University of London, suggests potential applications of the technology could include helping policymakers better assess the impact of visual impairment on patients, and helping architects to design more accessible buildings.
