A unique window coating technique can improve the energy efficiency of an average household.  The semitransparent photovoltaics are lightweight and colorful films capable of turning windows into heat insulators and electricity generators.  The trend of environment-friendly building, often referred as green building, has increased the popularity of advanced window coatings that keeps cooling or heating ...

Researchers test Einstein’s general relativity theory on a triple star system that is 4,200 light years away.  They found that both neutron star (heavy and dense) and white dwarf star (less massive) fall towards an outer dwarf at the same rate.  Any acceleration difference between inner white dwarf and neutron star is too small to ...

Researchers propose multidomain displays to improve viewing angle and color rendition.  It works with liquid crystal polymers, poly(di-n-alkylsiloxanes).  It can facilitate fabrication procedure and open new doors in the field of printed and organic electronics.  The liquid crystal display (LCD) market has fully appreciated the benefits of the liquid crystal state of matter, combining mobility and order, ...

The expansion of media services like Netfilx and Hulu gives rise to a new trend in entertainment industry. More and more users now prefer premium services over traditional television channels, where they can legally watch anything anytime they want on multiple platforms. There are hundreds of services that provide their users access to popular movies and sitcoms ...

New convolutional neural network can analyze compounds in the human breath and detect illnesses. The technology makes the whole process fast, less expensive, and more reliable. It can be used in forensics, medicine and environmental analysis. Artificial intelligence (AI) is creating a lot of buzz these days. Developers are integrating AI into almost everything: whether ...

Milky Way consists of very high amount of carbonaceous dust, and now similar type of cosmic dust has been observed in galaxies 11 billion light-years away from Earth.  This comes from a recently detected ultraviolet carbonaceous dust in a gamma-ray burst, GRB180325A.    Galaxies are gravitationally bound systems comprised of numerous individual parts such as stars, ...

New convolutional network learns to copy colors from one reference frame to subsequent frames.  While doing so, it can follow different objects and track through occlusions.  It can also track human poses.  Teaching machines to track objects in a video is one of the most difficult tasks in computer vision, mainly because it requires a ...

The new coating technique makes natural fabric water-repellent, and it works better than existing methods.  The fabrics have passed repeated washing tests and harsh abrasion tests without any degradation and damage to the coating. Waterproof fabrics are usually synthetic fibers that are coated or laminated with waterproofing materials like silicone elastomer, polyvinyl chloride (PVC), fluoropolymers, and ...

In this age of digital consumerism, almost nothing is free of cost especially entertainment. And even if there is, they are generally considered pirated or illegal. Over the last decade or so, many media streaming sites have emerged that provides streaming services and allow users to download their favorite movies and television shows but at a cost. ...

The brightness of any stellar object or any object in space is measured by the apparent magnitude of that body. Well, that’s just one way to do it. Apparent magnitude is the level of brightness witnessed by an observer on the Earth. Brightness and the magnitude value have an inverse relationship, i.e. more the brightness less ...

Astrophysicists determine new constraints on radii and tidal deformabilities of neutron stars.  They compared 2 billion theoretical models with gravitational waves captured in 2017.  This allowed them to deduce the size of neutron stars within a range of 1.5 kilometers: it varies from 12 to 13.5 km.  A neutron star is a collapsed core of a massive star ...

Researchers develop a neural network that can produce full 3D hair geometry from 2D image.  The network is capable of rendering up to 30,000 strands of hair in milliseconds. It can smoothly sample and interpolate variety of hairstyles, including wavy, curly and straight.  Rendering realistic hairs on machines is probably the toughest task when digitizing ...
