OBJECTIVE To analyze the in vitro force degradation of four different brands of elastomeric chains: American Orthodontics, Morelli, Ormco and TP Orthodontics. METHODS The sample consisted of 80 gray elastomeric chains that were divided into four groups according to their respective manufacturers. Chain stretching was standardized at 21 mm with initial force release ranging from 300 g to 370 g...

In this e-companion we provide proofs for some of the results stated in the manuscript titled: “When promotions meet operations: Cross-selling and its effect on call-center performance”. Specifically, we provide the sample path construction under the TP policy (in §A), and the key steps in the proof of Theorem 3.1 under Condition 1 (in §B). Due to space limitations, the proofs of Theorem 3.1 un...

It is by now well known that symmetries may be broken at high temperature. However, in renormalizable supersymmetric theories any internal symmetry gets always restored. In nonrenormalizable theories the situation is far less simple. We review here some recent work which seems to indicate that renormalizability is not essential for the restoration of internal symmetries in supersymmetry. Based ...

OBJECTIVE We sought to estimate the proportion of women immunized against tetanus while attending prenatal care in the developing countries. METHOD We computed the ratio of the percentage of births to women immunized against tetanus to the percentage of births to women with prenatal care (TP ratio). A TP ratio is lower than 100% if not every woman attending prenatal care is immunized. We used...

Keven & Akins suggest that innate stereotypies like TP/R may participate in the acquisition of tongue control. This commentary examines this claim in the context of speech motor learning and biomechanics, proposing that stereotypies could provide a basis for both swallowing and speech movements, and provides biomechanical simulation results to supplement neurological evidence for similarities b...

Historically, first case of TP was described by Scriba in 1885, though some authors believe that Virchow was the first one to describe this entity. Since TP was predominantly seen in tropics, various terms like tropical pyomyositis, myositis tropicans, and tropical myositis are used, but nowadays this entity is no longer confined only to tropics. Levine in 1971, reported the first case of TP fr...

We study the dynamical behavior of the BTZ(Banados-Teitelboim-Zanelli) black hole with the low-energy string effective action. The perturbation analysis around the BTZ black hole reveals a mixing between the dilaton and other fields. Introducing the new gauge(dilaton gauge), we disentangle this mixing completely and obtain one decoupled dilaton equation. We obtain the decay rate Γ of BTZ balck ...

Global biodiversity continues along a trajectory of decline despite enormous conservation efforts (Rands et al., 2010). This is also true in China, one of the most biodiversity-rich countries in the world (Liu and Raven, 2010; Ministry of Environmental Protection of China, 2010a). To fundamentally change this trajectory, it is essential to understand complex interactions among various forces af...

(Part of the results presented in this paper have already appeared in 5])-Abstract We investigate the complexity of the Con-guration REachability Problem (CREP) for two classes of nite weakly predictable cellular automata: the invertible and the additive ones. In both cases we prove that CREP belongs tp the \Arthur-Merlin" class CoAMM2].

This document describes an alternative integer linear programming (ILP) model for the so-called edge-disjoint paths (EDP) problem in undirected graphs. EDP is an N P-hard problem where exact methods are not able to produce high quality solutions. Therefore, we propose two different algorithms for combining exact and heuristic methods. On the one hand, we consider a restricted model that limits ...
