Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

It turns out the "10-year lifespan" printed on your LED box is often a total fantasy. I spent years falling for the marketing, only to end up standing on a ladder every six months replacing bulbs that ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

Abstract: A biasing method for a stacked field-effect transistor (FET)-based radio-frequency (RF) switch is proposed. The advantage of the method over conventional passive resistive biasing is the ...

Abstract: In this work, a semi-analytical compact model of random process fluctuations in nanosheet (NS) gate-all-around (GAA) complementary FET (CFET) is proposed, including work-function variation ...
