We present a different version of the well-known connection between Hopf–Galois structures and skew braces, building on recent paper A. Koch P. J. Truman. show that known results involve this easily carry over to new perspective, ones naturally appear. As an application, we insights study surjectivity correspondence, explaining in more detail role bi-skew braces theory.

OBJECTIVE To determine the relative risk reduction associated with prophylactic knee braces in the prevention of knee injuries in collegiate football players. DATA SOURCES An exhaustive search for original research was performed using the PubMed, SportDiscus, and CINAHL databases from 1970 through November 2006, with the search terms knee brace, knee braces, knee bracing and football, prophyl...

Prophylactic knee braces are designed to prevent and reduce the severity of ligamentous injuries to the knee. Conflicting evidence is reported concerning their efficacy. The purpose of this study was to determine the effect of prophylactic knee bracing on the proprioceptive parameters of balance and joint position sense. Active and passive joint position sense were assessed using the Cybex II +...

Debris flow is a very destructive natural disaster. This paper presents a novel masonry structure with strong resistance to debris flow—by using walls that are set with braces and filled with straw bricks. This structure was designed according to the concepts of sustainability. In order to study the dynamic response of this novel masonry structure under debris flow, finite element models of dif...

The routine use of functional knee braces in the anterior cruciate ligament-deficient, injured, or reconstructed knee, lacks biomechanical support. Although subjective reports favoring bracing are plentiful, objective proof of significant control of tibial translation is not. This in vivo study was designed to assess the effect of six popular braces on anterior tibial translation, isokinetic pe...

This study quantified and compared the efficacy of in-shoe orthoses and ankle braces in stabilizing the hindfoot and medial longitudinal arch in a cadaveric model of acquired flexible flatfoot deformity. This was addressed by combining measurement of hindfoot and arch kinematics with plantar pressure distribution, produced in response to axial loads simulating quiet standing. Experiments were c...

Several published articles suggest that an untreated progressive idiopathic scoliosis (IS) curve may present a poor prognosis into adulthood including back pain, pulmonary compromise, cor pulmonale, psychosocial effects, and even death [Rowe 1998, Danielsson et al 2006, Danielsson et al. 2007, Weinstein et al. 1981, Weinstein and Ponsetty 1983, Weinstein et al 2003]. Bracing, even though it has...

Abstract We consider the problem of finding an inductive construction, based on vertex splitting, triangulated spheres with a fixed number additional edges (braces). show that for any positive integer b there is such construction triangulations braces, having finitely many base graphs. In particular we establish bound maximum size graph braces linear in . case $$b=1$$ <mml:math xmlns:mml="http:...
