Many quantum materials have been nearly impossible to simulate mathematically because the computing time required is too long. Now a joint research group at Freie Universität Berlin and the Helmholtz-Zentrum Berlin (HZB, Germany) has demonstrated a way to considerably reduce the computing time. This could accelerate the development of materials for energy-efficient IT technologies of the future.
A study that asked children to assess three different robots showed that they responded most positively to simple robots shaped like flower pots, and were most sceptical of Pepper the robot, which looks more human.
Of ever-increasing concern for operating a tactical communications network is the possibility that a sophisticated adversary may detect friendly transmissions. Army researchers developed an analysis framework that enables the rigorous study of the detectability of ultraviolet communication systems, providing the insights needed to deliver the requirements of future, more secure Army networks.
Quantum systems are notoriously prone to errors and noise. In order to overcome this and build a functional quantum computer, physicists should ideally understand the noise across an entire system. That has been out of reach until now, with Dr Robin Harper and colleagues developing the first system-wide quantum algorithm to characterise noise.
Skoltech researchers have used the supercomputer to perform a very precise sensitivity analysis to reveal crucial parameters for different crop yields in the chernozem region of Russia, famous for its high-quality, fertile soil. Agricultural lands occupy 13 percent of the territory of Russia, droughts, dryness, humus reserves exhaustion are the major negative factor for national agriculture. Being able to simulate all possible variants, reveal the most crucial parameters without time-consuming and costly work is important.
Engineers at MIT have studied the simple act of shaving up close, observing how a razor blade can be damaged as it cuts human hair -- a material that is 50 times softer than the blade itself. They found that hair shaving deforms a blade in a way that is more complex than simply wearing down the edge over time.
University of Pittsburgh Associate Professor John A. Keith is using new quantum chemistry computing procedures to categorize hypothetical electrocatalysts that are "too slow" or "too expensive", far more thoroughly and quickly than was considered possible a few years ago.
A new algorithm developed in the lab of Jr-Shin Li at the McKelvey School of Engineering at Washington University in St. Louis provides a framework for solving complex linear inverse problems that doesn't require a supercomputer and also enhances security and privacy.
Now researchers at MIT and Caltech have shown that the weird, quantum effects of entanglement could theoretically give blackjack players even more of an edge, albeit a small one, when playing against the house.
At Japan Advanced Institute of Science and Technology, researchers have successfully established relationships between games and law of motions in mind through analogy of physics and game refinement theory.
