Mechanism of nonlinear biodynamic response of the human body exposed to whole-body vibration [PDF]

open access: yes, 2008
When the human body is exposed to mechanical vibration, the resonance frequencies of the frequency response functions, such as apparent mass and transmissibility, decrease with increasing magnitude of excitation. For the past two decades, this biodynamic

Whole-body vibration transmission during resistance vibration exercise [PDF]

open access: yesFrontiers in Sports and Active Living
IntroductionResistive exercise combined with whole-body vibration (WBV) and short-arm human centrifugation is being considered as a countermeasure to mitigate muscle and bone loss in astronauts during prolonged space missions. WBV may provide exercise benefits or adverse effects on organs and the lower back.

Raman Analysis of RNA Nucleotide Strands From SARS‐CoV‐2 Variants and Subvariants: A Step Forward in the Definition of “Raman Genome”

open access: yesAdvanced Science, EarlyView.
Main Raman signals in RNA, related to helical backbone, ribofuranose ring, and nitrogenous bases, are affected by secondary structures that cause hyperchromic effects and significantly alter the Raman intensity. ABSTRACT Raman spectra of RNA nucleotide strands extracted from 20 SARS‐CoV‐2 strains, including the original Japanese isolate, Alpha, Beta ...

Total vibrational excitation and transmission error of gears as index of vibration and noise of power transmissions.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1990
Gear vibration is induced by the excitation due to manufacturing/alignment errors and periodical chasnge of meshing tooth stiffness with progress of gear rotation. As an index for evaluating the degree of gear vibration and noise as functions of gear dimensions, accuracy and driving conditions, transmission error of gears and total vibrational ...

Illuminating point‐of‐care diagnostics with aggregation‐induced emission biosensors

open access: yesFlexMat, EarlyView.
This review highlights the application of aggregation‐induced emission luminogens (AIEgens) in point‐of‐care (POC) diagnostics for disease biomarker detection. It systematically examines a range of biosensing platforms, including lateral flow immunoassays, microfluidic chips, and electrochemiluminescence sensors, alongside their utility in detecting ...

A South African Language Teacher Educator's Reflective Journey Through Sociocultural Theory and Asset‐Based Mediation

open access: yesTESOL Quarterly, EarlyView.
Abstract This reflective article chronicles a South African English as a Medium of Instruction (EMI) university teacher educator's journey from professional disillusionment toward a more intentional, transformative praxis. The catalyst for this journey was the recurring observation of novice teachers abandoning dialogic, asset‐based pedagogies learned ...
