OBJECTIVE To evaluate the value of preoperative radiographic evaluations for total knee arthroplasty (TKA) revision. METHODS Thirty-one knees that were operated between 2006 and 2008, in a consecutive series of cases of TKA revision surgery were analyzed retrospectively. The following criteria were evaluated: number of wedges or structured bone grafts used for filling the bone defects; locati...

background: according to clinical observations, foot hyperpronation is very prevalent and may cause malalignment of the lower extremity, leading to structural and functional deficits in standing and walking. this study aimed at investigating the effect of foot hyperpronation on spine alignment in the standing position.   methods: thirty-five healthy males with an age range of 18-30 years partic...

There is a long-standing debate as to whether visual mental imagery relies entirely on symbolic (language-like) representations or also relies on depictive (picture-like) representations. We sought to discover whether visual mental imagery could evoke cortical activity with precise visual field topography (retinotopy). Participants received three conditions: the perception condition consisted o...

Motivated by properties of tensor networks, we conjecture that an arbitrary gravitating region $a$ can be assigned a generalized entanglement wedge $E\supset a$, such quasi-local operators in $E$ have holographic representation the full algebra generated $a$. The universe need not asymptotically flat or AdS, and asymptotic weakly gravitating. On static Cauchy surface $\Sigma$, propose is supers...

A large part of the scientific legacy Maurice Kleman concerns topological defects in liquid crystals. Here, we focus on very first article crystals coauthored with Jacques Friedel and devoted to linear cholesterics discovered 1921 by François Grandjean who observed them wedges made from partially cleaved mica sheets. interpreted thin (single) thick (double) lines as dislocations Burgers vectors...

Abstract This paper investigates the performance of a single and group laterally loaded barrettes using series numerical models in three-dimensional finite element software. The simulation both directions is verified by comparing predictions to field measurements previously published literature. defines soil wedge around barrette sheared at strain equivalent minimum shear value side or higher a...
