Minimum Sparsity of Unobservable Power Network Attacks

, 2016
Physical security of power networks under power injection attacks that alter generation and loads is studied. The system operator employs Phasor Measurement Units (PMUs) for detecting such attacks, while attackers devise attacks that are unobservable by ...

Direct Probing of Trap Dynamics in β‐Ga2O3 Schottky Barrier Diodes Using Single‐Voltage‐Pulse Characterization

Advanced Science, EarlyView.
A single‐pulse approach uncovers trap dynamics in β‐Ga2O3 Schottky barrier diodes. Transient current profiling reveals rapid electron capture, delayed trap filling, and clear thermal effects. Extracted trap densities, capture time constants, and activation energies indicate that this simple pulse technique enables effective evaluation of trap states ...

Ruptured peroneal aneurysm after infrapopliteal prosthetic bypass with Taylor patch

EJVES Short Reports, 2015
Introduction: A 45-year-old mailman underwent an implantation of a femoro-peroneal polytetrafluoroethylene (PTFE) bypass with a distal Taylor patch six years prior to admission after two failed autologous reconstructions and extensive fasciotomy.

RRAM Variability Harvesting for CIM‐Integrated TRNG

Advanced Electronic Materials, EarlyView.
This work demonstrates a compute‐in‐memory‐compatible true random number generator that harvests intrinsic cycle‐to‐cycle variability from a 1T1R RRAM array. Parallel entropy extraction enables high‐throughput bit generation without dedicated circuits. This approach achieves NIST‐compliant randomness and low per‐bit energy, offering a scalable hardware

Perceptions of metabolic syndrome management utilization in relation to patient experience and health-related quality of life

Exploratory Research in Clinical and Social Pharmacy
Background: One factor for the poor health outcomes among adult people with metabolic syndrome (MetS) is poor utilization of disease management resources, which may be attributable to prior experience with pharmacists (PEwP) and perceptions of disease ...
