p { margin-bottom: 0.1in; direction: rtl; line-height: 120%; text-align: right; }a:link { color: rgb(0, 0, 255); } In this paper, the reported experimental data related to electrical transport properties in bulk ZnO, ZnMgO/ZnO and ZnMgO/ZnO/ZnMgO single and double heterostructures were analyzed quantitavely and the most important scattering parameters on controlling electron concentratio...

The shape recognition of an object is important for dexterous manipulation by humans. Therefore, we have developed a haptic display that integrates both electrotactile and kinesthetic sensations to present shape information. However, the electrotactile display only presents the contact field between the object and the fingertip. Therefore, we propose a method of electrotactile stimulation using...

background: the main purpose of this study was to determine the relationship between serum vitamin d and the status of bone mineral density in patients with low-energy hip and distal radius fracture. methods: this retrospective case-control study was performed between january 2013 and january 2014. participants aged 55 years or older were divided to case group including 85 patients with low-ene...

OBJECTIVE The objective of this study was to fully characterize the mechanics of an in vivo impactor and correlate the mechanics with superficial cracking of articular surfaces. DESIGN A spring-loaded impactor was used to apply energy-controlled impacts to the articular surfaces of neonatal bovine cartilage. The simultaneous use of a load cell and displacement sensor provided measurements of ...

We investigate elastic energy-driven grain boundary migration in a strained copper bicrystal using an atomistically informed phase field model. In a bicrystal experiencing a uniform strain, the softer grain has a lower energy density and grows at the expense of the harder grain. In a bicrystal experiencing heterogeneous strain, the softer grain has a higher energy density, yet it still grows. O...

We propose a hybrid approach which employs the dynamical mean field theory (DMFT) self-energy for correlated, typically rather localized orbitals and conventional density functional (DFT) exchange-correlation potential less orbitals. implement this (plus charge density) self-consistent $\mathrm{DFT}+\mathrm{DMFT}$ scheme in basis of maximally Wannier using wien2k, wien2wannier, DMFT impurity so...

zno thin films were deposited on si(400) substrates by e-beam evaporation technique, and then post-annealed at different annealing temperatures (200-800°c). dependence of the crystallographic structure, nano-strain, chemical composition and surface physical morphology of these layers on annealing temperature were studied. the crystallographic structure of films was studied using x-ray diffracti...

background: the purpose of this study was to evaluate long-term changes in bone density profile among survivors of childhood acute lymphoblastic leukemia. patients and methods: this was a 5 year prospective study comprised of thirty-one survivors of childhood acute lymphoblastic leukemia with a mean age of 11.8 (4.6) years, who completed therapy at least 1 year previously (according to the all-...
