Design and Analysis of Low-Noise Amplifiers Using Chopper Stabilization Technique [PDF]

open access: yes, 2006
In this paper, the low-voltage and low-noise CMOS amplifier for surface-myoelectricity signal processing. First, the chopper-stabilized amplifier, which is one of the modulators, is adopted. Because the low frequency signal is modulated to high frequency

Stiffness‐Activated Stellate Cells Drive Pancreatic Cancer Liver Colonization via GMFG‐TNS4 Signaling

open access: yesAdvanced Science, EarlyView.
Fibrotic liver stiffness activates hepatic stellate cells through Piezo1‐dependent calcium influx and ER stress, promoting EV‐associated GMFG release. Delivered GMFG engages TNS4 in pancreatic cancer cells, triggering FAK/AKT signaling, adhesion, and fatty acid synthesis.

Realization of a Low-Distortion and Low-Noise CMOS Fully Differential Chopper Stabilized Amplifier [PDF]

open access: yes, 2014
本論文主要目的在設計與實現低雜訊及低失真的CMOS全差動截波穩定型放大器,應用於放大感測器所輸出的低頻且微弱的訊號 (如生醫系統的感測器感測出的訊號),並實現一個二階GM-C帶通濾波器,以及外加一個低通濾波器以構成完整之感測器讀出電路。此電路主要是利用調變(Modulation)的技巧,使其能有效地降低放大器電路本身所產生的低頻雜訊以及輸入偏移電壓所造成的解析度誤差。本論文所實現出的電路,在利用CIC所提供的TSMC0.35um CMOS 2P4M製程技術來進行模擬。全差動截波穩定型放大器中之運算放大器,

ZrO2 Aerogel‐Supported Pd Nanoparticles for Photothermal CO2 Reduction

open access: yesAdvanced Science, EarlyView.
Nanoparticle‐based aerogels are promising catalysts for photothermal reactions due to optical transparency, high surface area, and low thermal conductivity. Here, we present deposition of Pd nanoparticles on ZrO2 aerogel granules by a wet‐impregnation approach.

Intrinsic Dual‐Phase Regulated GeSe2 Nanoparticles Triggered by Ball‐Milling Treatment for Photonic Multi‐Valued Logic Circuits

open access: yesAdvanced Science, EarlyView.
We report the solid‐state ball milling, a traditional, reliable, mass‐productive material processing, to prepare the air‐stable and dual‐phase GeSe2‐x nanoparticles with extended photodetection feasibility toward optical‐wavelength regions. We further display photonic multi‐valued logic (MVL) circuit through the employment of a hybrid PMMA/GeSe2‐x ...

MAM‐Localized MANF Counteracts Microinflammatory Stress to Attenuate Mitochondrial Dysfunction and Cataractogenesis in High Myopia

open access: yesAdvanced Science, EarlyView.
Chronic microinflammation in high myopia suppresses MANF in lens epithelial cells. MANF normally resides within MAMs and promotes ubiquitin‐mediated degradation of the ER Ca2+ pump SERCA2. MANF loss causes pathological SERCA2 accumulation, MAM hyperassembly, and disrupted ER‐to‐mitochondria Ca2+ transfer, leading to mitochondrial failure, oxidative ...

Thin‐Film Thermal Sensors on Chitosan Substrates for Sustainable Transient Electronics

open access: yesAdvanced Electronic Materials, EarlyView.
Fully transient thin‐film temperature sensors are realized on pure chitosan substrates using Mo‐based RTDs and a‐IGZO/Mo thermistors. The devices exhibit high sensitivity, mechanical flexibility, humidity‐aware operation, and complete dissolution in natural solvents.

Protection Motivation Theory and Farmers' Participation in Futures Markets: Evidence From Germany

open access: yesAgribusiness, EarlyView.
ABSTRACT This study examines why German farmers show limited adoption of commodity futures contracts despite substantial price volatility, applying Protection Motivation Theory (PMT) to understand the cognitive processes driving participation decisions in futures markets. Survey data from 303 German farmers collected in 2024 were analyzed using Partial
