Credit: Argonne National Laboratory X-ray technology plays a vital role in medicine and research by providing non-invasive medical imaging and information about materials. Recent advances in X-ray technology enable brighter and more intense beams and the imaging of increasingly complex systems under real-world conditions, such as the interior of working batteries. To support these … Read more
An artist’s impression of a red quasar. Red quasars are obscured by gas and dust that can be blown away by the outflow from the supermassive black hole, eventually revealing the typical blue quasar. Authors: S. Munro and L. Klindt. License: Attribution (CC BY 4.0) Astronomers have found a striking correlation between the amount … Read more
Applying NESAdaBelief to optimize VQAs. The left side shows the calculation of quantum gradients using the quantum device parameter shift rule, and the right side shows the calculation of quantum gradients using BP. Optimization is performed using the obtained loss function according to algorithm1. Credit: Smart computing (2023). DOI: 10.34133/icomputing.0042 A team of researchers … Read more
A novel technique for broadband achromatic and polarization insensitive metalens (BAPIML) has been introduced to combat the chromatic aberration found in standard metals. The method uses the Rayleigh criterion for spot resolution and phase change material nanofins. This development holds the potential for advanced optical and imaging applications. Using novel differential design principles, researchers propose … Read more
Sample geometry and integrated Brillouin spectrum analysis at room temperature. aAn artist’s view of a LiCOF sample with a laser. bMeasured spectrum (blue) and simulation (red) of the SBS spectrum with a core diameter of 1.125 m. c, geometry of a LiCOF sample bonded on both sides to a UHNA fiber for bonding and … Read more
As new and powerful telescopes gather new data about the universe, they reveal the limits of older theories. Credit: Shutterstock Einstein’s theory of gravity general relativity has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own failure at spacetime singularities inside … Read more
