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:...

Regulation for calculating earthquake forces building in Indonesia keep developing. SNI 1726-2019 is the lastest regulation which has a return period of 2500 years, while 1726-2002 500 years. So old have to be strengthened. Steel braces good option resist lateral forces. In value response modification factor (R), overstrength (Ω0), and deflection amplification (Cd) eccentrically braced concrete...

The bicontraction of a vertex v of degree two in a graph, with precisely two neighbours v1 and v2, consists of shrinking the set {v1, v, v2} to a single vertex. The retract of a matching covered graph G, denoted by Ĝ, is the graph obtained from G by repeatedly bicontracting vertices of degree two. Up to isomorphism, the retract of a matching covered graph G is unique. If G is a brace on six or ...

Background: Rupture of anterior cruciate ligament (ACL) would cause instability and disability and if left untreated. Reconstruction is performed by different techniques including patellar bone graft, as the strongest device. Application of brace after ACL reconstructions has revealed doubtful results. Methods: One hundred ACL ruptured patients randomized into two groups were reconstructed with...

The main aim of this study, is to evaluate the seismic reliability of steel concentrically braced frame (SCBF) structures optimally designed in the context of performance-based design. The Monte Carlo simulation (MCS) method and neural network (NN) techniques were utilized to conduct the reliability analysis of the optimally designed SCBFs. Multi-layer perceptron (MLP) trained by back propagati...

Osteoarthritis of the knee is a debilitating condition affecting increasing numbers of individuals each year. One option for treatment is orthotic knee braces, but a little independent reviews have taken place to date on their relative outcomes for users. This study therefore evaluates the efficacy of different types of knee orthoses (braces) with regard to key aspects of use, including gait pa...

We investigate a new algebraic structure which always gives rise to set-theoretic solution of the Yang-Baxter equation. Specifically, weak (left) brace is non-empty set $S$ endowed with two binary operations $+$ and $\circ$ such that both $(S,+)$ $(S, \circ)$ are inverse semigroups they hold \begin{align*} \circ \left(b+c\right) = a\circ b - +a\circ c \qquad \text{and} a^- + a, \end{align*} for...

BACKGROUND Recent studies showed that finite element model (FEM) combined to CAD/CAM improves the design of braces for the conservative treatment of adolescent idiopathic scoliosis (AIS), using 2D measurements from in-brace radiographs. We aim to assess the immediate effectiveness on curve correction in all three planes of braces designed using CAD/CAM and numerical simulation compared to brace...
