University of Utah mathematicians propose a theoretical framework to understand how waves and other disturbances move through materials in conditions that vary in both space and time. The theory, ...

Reconstructing the phase of a field from intensity measurements is an old and ubiquitous challenge, known as the phase retrieval problem 1,2,3. It has found numerous applications spanning from ...

Active boundary heating and cooling can make a small object look much larger to thermal sensors, a step toward compact ...

Hotter objects typically glow brighter than cooler ones, making them stand out in infrared images. But a newly designed coating bucks the rule that hotter equals brighter. For certain wavelengths of ...

Mathematicians propose a theoretical framework to understand how waves and other disturbances move through materials in conditions that vary in both space and time. The theory is called 'field ...

The new technique generates an image (top right) from the speckle pattern created when light from the coloured numerals (top left) is scattered by the mostly opaque surface in the middle. (Courtesy: M ...

The Prototype Pattern involves cloning objects. Learn how to create both deep and shallow clones for instances in your program where creating a new object won't work. The Prototype Pattern is a common ...

When building applications, you often come across objects that are quite expensive to create. In some scenarios, the cost of creating new objects is high enough to impact application performance. Here ...
