Identifying Equipment Factors Associated with Snowplow Operator Fatigue
Safety, 2019 A recent body of research in fatigue management indicates that other factors, including in-cab and external equipment, contribute to operator fatigue. The goal of this project was to identify winter road maintenance equipment (in-cab and external) that ...

SIGNIFICANT WAVE HEIGHT DETERMINED FROM SEQUENCE OF X-BAND RADAR IMAGES USING TEAGER-HUANG TRANSFORM [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015 This work introduces a nonlinear and data-dependant method for extracting the significant wave height from a sequence of X-band radar images, which is based on the Teager-Huang Transform (THH).

Enhanced narrow-band operation of ultra-fast rectennas [PDF]
2016 41st International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz), 2016 An effective impedance matching technique for rectennas (an antenna coupled with rectifier) operating at specific frequencies is presented. The rectifier consists of a MIM junction with a molecular insulator. The method used two coplanar strip lines emerging from the antenna feed-point, to correct for the reactive component of the antenna impedance on ...

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Effective operators in t-channel single top production and decay
European Physical Journal C: Particles and Fields, 2018 The production of a single top quark in the t-channel and its subsequent decay is studied at NLO accuracy in QCD, augmented with the relevant dimension-6 effective operators from the Standard Model Effective Theory.
