Comparative Analysis of 6T, 7T, 8T, 9T, and 10T Realistic CNTFET Based SRAM

Journal of Nanotechnology, 2017
CMOS technology below 10 nm faces fundamental limits which restricts its applicability for future electronic application mainly in terms of size, power consumption, and speed. In digital electronics, memory components play a very significant role.

Multi-Scale Codes in the Nervous System: The Problem of Noise Correlations and the Ambiguity of Periodic Scales

, 2013
Encoding information about continuous variables using noisy computational units is a challenge; nonetheless, asymptotic theory shows that combining multiple periodic scales for coding can be highly precise despite the corrupting influence of noise ...

Noise in a CCD image sensor and the new low-noise read-out method.

The Journal of the Institute of Television Engineers of Japan, 1985
固体撮像素子を放送用の高画質撮像素子として適用するために, 付加ノイズ発生要因・量共に少ないCCD型の低雑音化と今後の高画質化の可能性などについて種々の検討を行った.まず, ランダムノイズと固定パターンノイズ (FPN) を分離して定量的に測定することができる分析評価法を数した.次に, 新開発の積分型相関二重サンプリング法, および遅延差雑音除去法を用いた低雑音化信号読出し回路により, ランダムノイズを暗電流のショットノイズの程度まで低減できることを示し, ノイズ低減効果の解析結果との良い一致も得た.さらに, 暗電流とFPNの温度依存性の測定結果から, FPNの主因が暗電流の画素ごとのむらによることも確かめた.これらの結果, CCD型撮像素子の今後の低雑音化には, 信号電荷読出し部のアンプノイズと,

PEDOT‐Based Eutectogel Electrode Arrays for Enhanced High‐Resolution Electrogastrography: Fabrication, Stability, and Wearable Performance

Advanced Functional Materials, EarlyView.
Here, we present a high‐density PEDOT eutectogel electrode array for enhanced body surface gastric mapping. Silver electrodes are blade‐coated onto flexible substrates, followed by electrogelation of PEDOT:PSS and the deposition of a PEDOT:LS eutectogel.

Maximal viral information recovery from sequence data using VirMAP

Nature Communications, 2018
Viral taxonomic characterization from metagenomic data suffers from high background noise and signal crosstalk. Here, the authors develop VirMAP, a novel pipeline for analyses of metagenomic data that classifies viral reconstructions independent of ...

Formation of Stable Amorphous Calcium Phosphate and Collagen Assemblies by a Versatile Spray‐Drying Approach

Advanced Functional Materials, EarlyView.
Amorphous calcium phosphate (ACP) microparticles with long‐term and thermal stability are prepared with or without collagen using a scalable one‐pot spray‐drying process. Under simulated physiological conditions, they crystallize into biomimetic bone mineral and, when combined with collagen, form extrudable, fibrillar bone‐like 3D constructs.

Nanoscale Mapping of Plasmonic Charge Transport in Nano‐Resonators Based on Resistive Switching Materials

Advanced Functional Materials, EarlyView.
In this strategy, a conductive nano‐probe is employed to induce nanoscale phase transitions and map the nanoscale conductivity and trap density of GST films. By utilizing the contrasting properties of phase‐change states, nano‐resonators are fabricated that exhibit plasmonic conduction and dramatically different transport characteristics.

Digital Actuation Control of Soft Robotic Origami With Self‐Folding Liquid Crystal Elastomer Hinges

Advanced Functional Materials, EarlyView.
Self‐folding soft‐rigid hybrid robotic origami is enabled by liquid crystal elastomer actuators with embedded Joule heating and closed‐loop digital control. Digitally addressable hinges provide reversible and programmable transitions between distinct folded states while maintaining actuation performance at high cycle counts (over 1500).
