How deep is a mirror? It depends, but the calculations are more precise now
Licht reflects from a mirror, but where exactly does this reflection happen? Well, it depends, Martin van Exter and Corné Koks discovered. Their precise calculations, published in Optics Express, are important for designing optical cavities for quan.....»»
Precise stirring conditions key to optimizing nanostructure synthesis
Stirring allows for homogenization and efficient gas exchange—this fact has been known for decades. Controlling the stirring rate during the nanocluster synthesis is pivotal in achieving nanostructures with well-defined sizes, structures, optical p.....»»
The link between fuzzy images and quantum fields
Mathematical solutions to thorny quantum problems can be found more quickly by exploiting the correspondence between the statistical methods used in deep learning and techniques for implementing quantum simulations, a team led by a RIKEN researcher h.....»»
Is the Paris Olympics’ Swimming Pool ‘Slow’? Let’s Dive into the Math
Controversy surrounds whether the Olympic pool in the Paris La Défense Arena is not deep enough and slows swimmers. Is this contention true?.....»»
Lemurs use long-term memory, smell, and social cues to find food
How do foraging animals find their food? A new study by New York University researchers shows that lemurs use smell, social cues, and long-term memory to locate hidden fruit—a combination of factors that may have deep evolutionary roots......»»
Water delivered to the mantle by aluminum enriched hydrated slabs?
Dense hydrous magnesium silicates (DHMSs) are generally considered as primary water carriers from the shallow lithosphere to the deep mantle transition region (MTR; 410–660 km in depth). Among DHMSs, Superhydrous phase B (hereafter, SuB) holds the.....»»
Modeling Earth systems at a quintillion calculations per second
Climate models compute vast amounts of information about Earth's climate system—from small water droplets to large-scale weather patterns—to re-create past climate or predict future climate. Accurately re-creating how Earth's energy (measured in.....»»
Scientists equip Australian sea lions with cameras to explore previously unmapped ocean habitats
What lies deep beneath ocean surfaces is often a mystery. In Australia, many underwater habitats have not been mapped, and researchers know little about them. Now, scientists are working to change that by employing sea lions as videographers......»»
Man suffers heart problem after rapid weight loss: A GLP-1 cautionary tale
The man developed atrial fibrillation and required hospitalization. Enlarge (credit: Getty | Spauln) The dose makes the medicine—and for many critical prescription drugs, the dose depends on a patient's body weight. Us.....»»
Oceans without sharks would be far less healthy, says new research
There are more than 500 species of sharks in the world's oceans, from the 7-inch dwarf lantern shark to whale sharks that can grow to over 35 feet long. They're found from polar waters to the equator, at the water's surface and miles deep, in the ope.....»»
Deep sea mining opponents suffer major setback
Opponents of deep sea mining suffered a serious setback Friday when they failed to take a first step toward an international moratorium on the controversial practice......»»
A deep dive into how developers trick App Store review into approving malicious apps
We recently reported on how multiple pirate streaming apps for iOS managed to get approved on the App Store by tricking the review process. Although we briefly mentioned some of the techniques used by these developers, 9to5Mac has now taken a deep di.....»»
Samsung’s (normally) expensive Chromebook just got a $300 price cut
Best Buy has a deep discount on the ageing but still respectable Samsung Galaxy Chromebook 2, bringing it down to just $399 -- perfect for students......»»
Ancient Antarctic microorganisms are aggressive predators
In Antarctica there is a small lake, called Deep Lake, that is so salty it remains ice-free all year round despite temperatures as low as -20°C in winter. Archaea, a unique type of single-celled microorganism, thrive in this bitterly cold environmen.....»»
Rubin Observatory"s 3.5-meter secondary mirror installed
Vera C. Rubin Observatory's 3.5-meter secondary mirror has been installed on the Simonyi Survey Telescope on Cerro Pachón in Chile. The glass mirror—made by Corning Advanced Optics and polished by L3Harris Technologies—is the first permanent com.....»»
Does AI in the classroom facilitate deep learning in students?
Multitasking robots collaborate with humans in large warehouses, and chatbots respond to queries on banking websites. Artificial intelligence assistants even sort documents for law firms. William & Mary Assistant Professor of Computer Science Janice.....»»
Uniquely precise: New value for the half-life of samarium-146
Researchers at the Paul Scherrer Institute PSI and the Australian National University have re-determined the half-life of samarium-146 with great precision. The result fits perfectly with the data astrophysicists and geochemists have obtained from ex.....»»
Polarization and wavelength routers based on diffractive neural network
The concept of deep diffractive neural networks (D2NN) was introduced by Professor Ozcan's research team in 2018. D2NN combines the principles of light diffraction with the functionalities of neural networks. It consists of a series of continuous dif.....»»
Pyramid optical networks for unidirectional image magnification and demagnification
In Light: Science & Applications journal UCLA researchers introduce an innovative design for diffractive deep neural networks (D2NNs). This new architecture, termed Pyramid-D2NN (P-D2NN), achieves unidirectional image magnification and demagnificatio.....»»
