Knowledge of and attitudes towards concussion in cycling: A preliminary study [PDF]

open access: yes, 2019
The aim of this study was to investigate the knowledge of and attitudes towards concussion in cycling. An abbreviated Rosenbaum Concussion Knowledge and attitudes Survey (RoCKAS) was distributed online via social media and completed by 1990 respondents ...

Stability for Vertex Cycle Covers

open access: yesThe Electronic Journal of Combinatorics, 2017
In 1996 Kouider and Lonc proved the following natural generalization of Dirac's Theorem: for any integer $k\geq 2$, if $G$ is an $n$-vertex graph with minimum degree at least $n/k$, then there are $k-1$ cycles in $G$ that together cover all the vertices.This is tight in the sense that there are $n$-vertex graphs that have minimum degree $n/k-1$ and ...

Stability of cycles and expectations [PDF]

open access: yesJournal of Economic Theory, 1986
The actual dynamics of an economy depends on how agents forecast the future at every date as a function of their information on the past, while possibly learning the structure of their environment. We show in the case of a one-dimensional state variable that under mild conditions on expectations functions, a given cycle with perfect foresight that is ...

Cycling [PDF]

open access: yes, 2006
The purpose of this article was to establish whether previously reported oxygen-to-mass ratios, used to predict flat and hill-climbing cycling performance, extend to similar power-to-mass ratios incorporating other, often quick and convenient measures of

Acute post-exercise recovery strategies in Cycling: A Review [PDF]

open access: yes, 2018
Cycling events often include multiple races a day or racing over consecutive days. Congested competition schedules and increased training load have led to the implementation of recovery strategies; with the goal of alleviating postexercise fatigue and ...

Effect of Lateral Dimension of Natural Graphite on Fabrication of Three-Dimensional Graphene Aerogels for High-performance Li-metal anodes

open access: yesInternational Journal of Electrochemical Science, 2021
Lithium metal, regarded as one of the most potential anodes for future battery systems, has attracted much attention for a long time. Nonetheless, uncontrollable Li dendrites growth and almost infinite volume change hinder the reliable implementation of ...

Crosslinked Carbon Nanotubes/Polyaniline Composites as a Pseudocapacitive Material with High Cycling Stability

open access: yesNanomaterials, 2015
The poor cycling stability of polyaniline (PANI) limits its practical application as a pseudocapacitive material due to the volume change during the charge-discharge procedure. Herein, crosslinked carbon nanotubes/polyaniline (C-CNTs/PANI) composites had

New Synthesis route of Iron-Based Catalyst for Electrochemical Oxygen Reduction Reaction

open access: yesInternational Journal of Electrochemical Science, 2020
Among existed oxygen reduction electrocatalysts, iron-based catalysts have shown great advantages of low cost and extraordinary reactivity, which are even comparable to commercialized platinum based catalysts. However, the propensity of iron catalysts to

Stability of heteroclinic cycles in ring graphs

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2022
Networks of interacting nodes connected by edges arise in almost every branch of scientific inquiry. The connectivity structure of the network can force the existence of invariant subspaces, which would not arise in generic dynamical systems. These invariant subspaces can result in the appearance of robust heteroclinic cycles, which would otherwise be ...
