Researchers used the Wrangler supercomputer at the Texas Advanced Computing Center to uncover the root cause of the 'beta anomaly' -- a discrepancy between the expected return on high-risk assets and their actual return. The team found that investors who are attracted to the lottery-like characteristics of these stocks push their prices higher than theory would predict, thereby lowering their future returns.
A team of electrical engineers at The University of Texas at Austin, in collaboration with Peking University scientists, has developed the thinnest memory storage device with dense memory capacity, paving the way for faster, smaller and smarter computer chips for everything from consumer electronics to big data to brain-inspired computing.
From cars and bicycles to airplanes and space shuttles, manufacturers around the world are trying to make these vehicles lighter, which helps lower fuel use and lessen the environmental footprint. But with the industry relying on petroleum products to make carbon fiber today, could we instead use renewable sources?
The Center for Computational Oncology developed computer models to predict how cancer will progress in a specific individual, based on tissue, cellular and subcellular protein signaling responses. The models can predict how brain tumors (gliomas) will grow with much greater accuracy than previous models. Recently, the group began a clinical study to predict how an individual's cancer will progress after one cycle of therapy, and to use that prediction to plan the course of treatment.
Researchers have improved the control of a key robotic component to better ensure the safety of humans. They published their results in IEEE/CAA Journal of Automatica Sinica (JAS), a joint publication of the IEEE and Chinese Association of Automation. The team, based at Nankai University, China, focused on series elastic actuators.
Use your smartphone to check how clean the air is, whether food is fresh or a lump is malignant. This has all come a step closer thanks to a new spectrometer that is so small it can be incorporated easily and cheaply in a mobile phone. The little sensor developed at TU Eindhoven is just as precise as the normal tabletop models used in scientific labs. The researchers present their invention in Nature Communications.
The iCub humanoid robot represents a standardized common open-source platform for research on embodied artificial intelligence (AI). It is available in 36 copies in laboratories across Europe, USA, South Korea, Singapore and Japan and more than hundred researchers worldwide contribute to develop its skills. Research activities explored the whole spectrum of AI-related areas, ranging from control to machine learning, human-robot interaction, and language acquisition. It is one of the largest open-source teams in the world.
Engineers have shown that a widely used method of detecting single photons can also count the presence of at least four photons at a time. The researchers say this discovery will unlock new capabilities in physics labs working in quantum information science around the world, while providing easier paths to developing quantum-based technologies.
UTA and University of Vermont researchers developed an optical medium in which multiple beams of light can autocorrect their properties without affecting other beams. This could lead to a dramatic reduction in the cost and energy consumption of high-speed internet communications.
Research teams all over the world are exploring different ways to design a working computing chip that can integrate quantum interactions. Now, Australian and Dutch engineers believe they have cracked the problem, reimagining the silicon microprocessors we know to create a complete design for a quantum computer chip that can be manufactured using mostly standard industry processes and components.
