Physical fitness, physical activity and adiposity: associations with risk factors for cardiometabolic disease and cognitive function across adolescence

open access: yesBMC Pediatrics, 2022
Background The cross-sectional associations between physical activity, physical fitness and adiposity with risk factors for cardiometabolic disease (particularly novel ones such as inflammatory cytokines) and cognitive function across the period of ...

Reliability of Near-Infrared Spectroscopy with and without Compression Tights during Exercise and Recovery Activities

open access: yesSports, 2023
Near-infrared spectroscopy (NIRS) is widely used in sports science research, despite the limited reliability of available data. The aim of the present study was to assess the reliability of NIRS with and without compression tights.

Shape Complexity in Turbulence [PDF]

open access: yes, 1998
The shape complexity of irregular surfaces is quantified by a dimensionless area-volume measure. A joint distribution of shape complexity and size is found for level-set islands and lakes in two-dimensional slices of the scalar field of liquid-phase ...

Microstructures and mechanical properties of zirconium-containing 7×××aluminum alloy prepared by selective laser melting

open access: yesCailiao gongcheng, 2021
The preparation of 7×××series aluminum alloy by selective laser melting technology (SLM) is hindered by hot tearing. Novel ZrH2 modified 7075 composite powders were prepared by the low-energy ball milling technology.

Algebraic Shape Invariant Models [PDF]

open access: yes, 1998
Motivated by the shape invariance condition in supersymmetric quantum mechanics, we develop an algebraic framework for shape invariant Hamiltonians with a general change of parameters. This approach involves nonlinear generalizations of Lie algebras. Our

Microstructures and Properties Evolution of Al-Cu-Mn Alloy with Addition of Vanadium

open access: yesMetals, 2016
The effect of the vanadium addition on the microstructure, the precipitation behavior, and the mechanical properties of the Al-5.0Cu-0.4Mn alloy has been studied. The as-cast Al-5.0Cu-0.4Mn alloy was produced by squeeze casting and the heat treatment was

Shape Tiling [PDF]

open access: yesThe Electronic Journal of Combinatorics, 1996
Given a list $1\times 1, 1\times a, 1\times b, \dots, 1\times c$ of rectangles, with $a,b,\dots,c$ non-negative, when can $1\times{t}$ be tiled by positive and negative copies of rectangles which are similar (uniform scaling) to those in the list? We prove that such a tiling exists iff $t$ is in the field $Q(a,b,\dots,c)$.

Conservation Laws shape Dissipation [PDF]

open access: yes, 2018
Starting from the most general formulation of stochastic thermodynamics---i.e. a thermodynamically consistent nonautonomous stochastic dynamics describing systems in contact with several reservoirs---, we define a procedure to identify the conservative ...
