Scaling Logic Area With Multitier Standard Cells

IEEE Journal on Exploratory Solid-State Computational Devices and Circuits
While the footprint of digital complementary metal-oxide–semiconductor (CMOS) circuits has continued to decrease over the years, physical limitations for further intralayer geometric scaling become apparent.

Angularly Stable Frequency Selective Surface Combined with a Wide-Scan Phased Array [PDF]

, 2018
A five-layer frequency selective surface (FSS) composed of subwavelength elements with large harmonic rejection bandwidth is presented. The FSS design is based on an equivalent circuit model, where the interlayer interaction is only described with a ...

A Closer Look at the Chaotic Ring Oscillators based TRNG Design

Transactions on Cryptographic Hardware and Embedded Systems, 2023
TRNG is an essential component for security applications. A vulnerable TRNG could be exploited to facilitate potential attacks or be related to a reduced key space, and eventually results in a compromised cryptographic system. A digital FIRO-/GARO-based

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Si and SiGe Nanowire for Micro-Thermoelectric Generator: A Review of the Current State of the Art

Frontiers in Materials, 2021
In our environment, the large availability of wasted heat has motivated the search for methods to harvest heat. As a reliable way to supply energy, SiGe has been used for thermoelectric generators (TEGs) in space missions for decades.
