Journal of Marine Science and Engineering, 2022 This paper investigates the fatigue cyclic deformation behavior of mid-carbon steel. Uniaxial tensile loading tests and fatigue tests under constant and multi-step amplitude loading steps are performed to characterize the influence of loading history ...

The spiral troughs of Mars as cyclic steps [PDF]
Journal of Geophysical Research: Planets, 2013 AbstractWe combine observations of stratigraphy, morphology, and atmospheric processes to relate the spiral troughs on Mars' polar layered deposits to a class of features known as cyclic steps. Cyclic steps are quasi‐stable, repeating, and upstream‐migrating bed forms that have been studied in terrestrial and submarine environments.

Structure and dynamics underlying elementary ligand binding events in human pacemaking channels
eLife, 2016 Although molecular recognition is crucial for cellular signaling, mechanistic studies have relied primarily on ensemble measures that average over and thereby obscure underlying steps. Single-molecule observations that resolve these steps are lacking due

Subunit promotion energies for channel opening in heterotetrameric olfactory CNG channels.
PLoS Computational Biology, 2022 Cyclic nucleotide-gated (CNG) ion channels of olfactory sensory neurons contain three types of homologue subunits, two CNGA2 subunits, one CNGA4 subunit and one CNGB1b subunit. Each subunit carries an intracellular cyclic nucleotide binding domain (CNBD)

A mechanistic study of the EC′ mechanism – the split wave in cyclic voltammetry and square wave voltammetry [PDF]
, 2016 In this paper, a detailed investigation of electrochemical reactions coupled with homogenous chemical steps using cyclic voltammetry (CV) and square wave voltammetry (SWV) was carried out to study the electrocatalytic (EC’) mechanism.

Development of a Step Counting Algorithm Using the Ambulatory Tibia Load Analysis System for Tibia Fracture Patients [PDF]
, 2018 Introduction: Ambulation can be used to monitor the healing of lower extremity fractures. However, the ambulatory behavior of tibia fracture patients remains unknown due to an inability to continuously quantify ambulation outside of the clinic.

A fatigue crack initiation model incorporating discrete dislocation plasticity and surface roughness [PDF]
, 2007 Although a thorough understanding of fatigue crack initiation is lacking, experiments have shown that the evolution of distinct dislocation distributions and surface roughness are key ingredients.

Cyclic steps formed by turbidity currents
Journal of Japan Society of Civil Engineers, Ser. A2 (Applied Mechanics (AM)), 2011 Levees of channels formed due to turbidity currents on submarine fans are often covered with step like bedforms. Circumstantial evidences emerged with numerical and experimental studies have suggested these sediment waves should probably be cyclic steps.
