The λ-Point Map between Two Legendre Plane Curves

open access: yesMathematics, 2023
The λ-point map between two Legendre plane curves, which is a map from the plane into the plane, is introduced. The singularity of this map is studied through this paper and many known plane map singularities are realized as special cases of this ...

Development and Evaluation of a Slip Detection Algorithm for Walking on Level and Inclined Ice Surfaces

open access: yesSensors, 2022
Slip-resistant footwear can prevent fall-related injuries on icy surfaces. Winter footwear slip resistance can be measured by the Maximum Achievable Angle (MAA) test, which measures the steepest ice-covered incline that participants can walk up and down ...

Perturbation-based balance training: Principles, mechanisms and implementation in clinical practice

open access: yesFrontiers in Sports and Active Living, 2022
Since the mid-2000s, perturbation-based balance training has been gaining interest as an efficient and effective way to prevent falls in older adults. It has been suggested that this task-specific training approach may present a paradigm shift in fall ...

Applications of Black Solider Fly (Hermetia illucens) Larvae Frass on Sweetpotato Slip Production, Mineral Content and Benefit-Cost Analysis

open access: yesAgronomy, 2022
Black soldier fly (Hermetia illucens) larvae (BSFL) production is increasing, which will leaves substantial amounts of leftover excrement, called ‘frass’ that may be a beneficial organic fertilizer.

The plume-dependent granite-rhyolite magmatism

open access: yesЛитосфера, 2018
The plume-dependent magmatism is widespread and well justified. The bulk of it is represented by flood basalts, basalts of oceanic islands (OIB), and basalts of oceanic plateaus (OPB), though the whole scope of plume magmatism is very diverse.

Development of a Portable Device for Surface Traction Characterization at the Shoe–Floor Interface

open access: yesSurfaces, 2022
Slip and fall accidents are widespread in workplaces and on walkways. Slipping is generally initiated by a sudden change in the flooring properties or due to a low available traction at the shoe–floor interface. To measure shoe-floor traction, mechanical

Traction Performance of Common Formal Footwear on Slippery Surfaces

open access: yesSurfaces, 2022
Traumatic injuries caused due to slipping and falling are prevalent in India and across the globe. These injuries not only hamper quality of life but are also responsible for huge economic and compensation burdens.

Analysis of Postural Instability in the Upright Position on Narrow Platforms and the Interactions with Postural Constraints

open access: yesSensors, 2021
Background: Loss of balance is a considerable risk factor for workers while using ladders, because they are required to maintain static postural balance on platforms of a restricted size.

Velocity-dependent quantum phase slips in 1D atomic superfluids [PDF]

open access: yes, 2016
Quantum phase slips are the primary excitations in one-dimensional superfluids and superconductors at low temperatures but their existence in ultracold quantum gases has not been demonstrated yet.
