purpose trainers and physical fitness coaches’ need a useful tool to assess training loads to avoid overtraining. however, perceived scales or questionnaires were required. therefore, the purpose of this study was to assess whether a short 8-item questionnaire of fatigue could be a useful tool for monitoring changes in perceived training load and strain among elite rugby sevens (7s) players dur...

conclusions pci was accompanied by some improvement in left atrial deformation indices as assessed by tissue doppler imaging. revascularization can, therefore, improve patient outcome. results regarding changes in left trial functional parameters after pci, those such as the strain of the septal wall and the anterior and inferior walls and the strain rate of the anterior and lateral walls signi...

The effect of uniaxial strain on the photocurrent spectrum of semiconducting single-wall carbon nanotubes is measured. The energy of the lowest-lying free electron transition is observed to shift with strain as predicted by a simple noninteracting model. The higher-order transitions also shift with strain, but being excitonic, their strain dependence differs from the predictions for the free ca...

The density of states and the AC conductivity of graphene under uniform strain are calculated using a new Dirac Hamiltonian that takes into account the main three ingredients that change the electronic properties of strained graphene: the real displacement of the Fermi energy, the reciprocal lattice strain and the changes in the overlap of atomic orbitals. Our simple analytical expressions for ...

The unique crystalline protection of the surface states in topological crystalline insulators has led to a series of predictions of strain-generated phenomena, from the appearance of pseudo-magnetic fields and helical flat bands to the tunability of Dirac surface states by strain that may be used to construct 'straintronic' nanoswitches. However, the practical realization of this exotic phenome...
