A new, miniature, low-frequency antenna with enhanced bandwidth will enable robust networking among compact, mobile robots in complex environments. In a collaborative effort between the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory and the University of Michigan, researchers developed a novel design approach that improves upon limitations of conventional antennas operating at low…

Researchers discovered a way to further enhance quantum systems to provide soldiers with more reliable and secure capabilities on the battlefield. Specifically, this research informs how future quantum networks will be designed to deal with the effects of noise and decoherence, or the loss of information from a quantum system in the environment. As one…

According to modern particle physics, matter produced when neutron stars merge is so dense that it could exist in a state of dissolved elementary particles. This state of matter, called quark-gluon plasma, might produce a specific signature in gravitational waves. Physicists have now calculated this process using supercomputers. In 2017 it was discovered for the…

An academic has achieved a milestone in statistical/mathematical physics by solving a 100-year-old physics problem — the discrete diffusion equation in finite space. The long-sought-after solution could be used to accurately predict encounter and transmission probability between individuals in a closed environment, without the need for time-consuming computer simulations. In his paper, published in Physical…

Getting to the doctor’s office for a check-up can be challenging for someone with a neurological disorder that impairs their movement, such as a stroke. But what if the patient could just take a video clip of their movements with a smart phone and forward the results to their doctor? Using rats that had incurred…

A team of researchers have developed a deep learning model that is capable of classifying a brain tumor as one of six common types using a single 3D MRI scan, according to a new study. «This is the first study to address the most common intracranial tumors and to directly determine the tumor class or…

We all have an internal clock but what makes us tick? Scientists have developed new artificial intelligence (AI) and machine learning (ML) technology to understand how gene expression regulates an organism’s circadian clock. Circadian rhythms, such as the sleep-wake cycle, are innate to most living organisms and critical to life on Earth. The word circadian…

Turing machines are widely believed to be universal, in the sense that any computation done by any system can also be done by a Turing machine. In a new article, researchers present their work exploring the energetic costs of computation within the context of Turing machines. At a high level, these machines are similar to…

Researchers present a 39 GHz transceiver with built-in calibration for fifth-generation (5G) applications. The advantages to be gained include better quality communications as well as cost-effective scalability. A team of more than 20 researchers at Tokyo Tech and NEC Corporation has successfully demonstrated a 39 GHz transceiver that could be used in the next wave…

It has been few years since physical key boards have been replaced by on-screen touch sensors for wireless devices such as cellular phones. This eventually triggered the modern day smartphone-era by introducing large-screen displays on portable devices. On the 27th of March, a University-Industry research consortium lead by Pohang University of Science and Technology (POSTECH)…
