Low Voltage Floating Gate MOS Transistor Based Four-Quadrant Multiplier [PDF]

, 2014
This paper presents a four-quadrant multiplier based on square-law characteristic of floating gate MOSFET (FGMOS) in saturation region. The proposed circuit uses square-difference identity and the differential voltage squarer proposed by Gupta et al.

Metabolic Reprogramming Driven by Trophoblasts and Decidual XCR1+PMN‐MDSC Crosstalk Controls Adverse Outcomes Associated With Advanced Maternal Age

Advanced Science, EarlyView.
The interaction between trophoblasts and decidual polymorphonuclear myeloid‐derived suppressor cells (dPMN‐MDSCs) via the XCL1–XCR1 axis is crucial for fetal development during the third trimester. Disruption of this axis impairs FOXO1 activity and causes metabolic imbalance in dPMN‐MDSCs, contributing to adverse outcomes associated with advanced ...

Ion‐Electron Fusion Transparent Film for Interactive Soft Robotics

Advanced Science, EarlyView.
An ion‐electron fusion transparent film with stable conductivity, high optical transmittance, and a broad linear strain‐sensing range of up to 300% is developed, attributed to the synergistic effects of ion penetration and microcrack design. When applied to soft robots, this film imparts proprioceptive sensing and underwater visible light communication

Optimal control set expansion method for three‐phase voltage source converter with slip window selection and online parameter modification

IET Power Electronics
Finite control set model predictive control (FCS‐MPC) has been widely used in the control of three‐phase voltage source converter (VSC), but its control performance declines sharply at low sampling frequencies.
