Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of consumer electronic devices, including laptop adapters, LED driver power ...

Cartridge-based consoles have often been celebrated for their robust and reliable media. You put a simple ROM chip in a tough ...

LED Christmas lights may be efficient, but can you use them worry-free? We talked to an expert about how proper usage and ...

Analyzing stochastic cell-to-cell variability can potentially reveal causal interactions in gene regulatory networks.

Researcher at LiU have developed a technique where visible light can be used to create electrodes from conductive plastics ...

Visible light can be used to create electrodes from conductive plastics completely without hazardous chemicals. This is shown ...

Researchers in Sweden have unveiled a way to create high-performance electronic electrodes using nothing more than visible light and specially designed water-soluble monomers. This gentle, ...

The microscopic processes taking place in superconductors are difficult to observe directly. Researchers at the RPTU ...

Microscopic fibers secretly shape how every organ in the body works, yet they’ve been notoriously hard to study—until now. A new imaging technique called ComSLI reveals hidden fiber orientations in ...

Abstract: In this paper, two LED emitting circuits are implemented in a VLC positioning system, a regular Bias-Tee and a circuit proposed by Ghassemlooy, aiming to provide the system with portability ...

Abstract: This paper proposes a new current balancing method for alternating current (AC) - light emitting diodes (LED). The proposed method uses the bi-directional current mirror circuit with ...
