Uma diversidade de alterações osteoarticulares tem sido descrita em pacientes em hemodiálise crônica. Objetivo: Verificar a proporção e o tipo de manifestação musculoesquelética (MME) nos pacientes em programa de hemodiálise, em três centros da região metropolitana do Recife, e relacionálas com as variáveis sexo, etnia, idade atual do paciente e, ao iniciar a diálise, tempo de tratamento dialít...

What is the meaning of saying that random variables {X(1), em leader, X(n)} (such as aptitude scores or hypothetical response time components), not necessarily stochastically independent, are selectively influenced respectively by subsets {Gamma(1), em leader, Gamma(n)} of a factor set Phi upon which the joint distribution of {X(1), em leader, X(n)} is known to depend? One possible meaning of t...

INTRODUCTION Dissemination of educational research is critical to improving medical education, promotion of faculty and ultimately patient care. The objective of this study was to identify the top 25 cited education articles in the emergency medicine (EM) literature and the top 25 cited EM education articles in all journals, as well as report on the characteristics of the articles. METHODS Tw...

Tony Robinson Cambridge University Engineering Department Cambridge CB2 IPZ England [email protected] The speech waveform can be modelled as a piecewise-stationary linear stochastic state space system, and its parameters can be estimated using an expectation-maximisation (EM) algorithm. One problem is the initialisation of the EM algorithm. Standard initialisation schemes can lead to poor forma...

INTRODUCTION Both the Accreditation Council for Graduate Medical Education (ACGME) and the American Osteopathic Association (AOA) require core faculty to engage in scholarly work, including publication in peer-reviewed journals. With the ACGME/AOA merger, we sought to evaluate the frequency of publication in high-impact peer-reviewed EM journals from authors affiliated with osteopathic emergenc...

Memories that are recalled while working memory (WM) is taxed, e.g., by making eye movements (EM), become blurred during the recall + EM and later recall, without EM. This may help to explain the effects of Eye Movement and Desensitisation and Reprocessing (EMDR) in the treatment of post-traumatic stress disorder (PTSD) in which patients make EM during trauma recall. Earlier experimental studie...

BACKGROUND In adults, erythema multiforme (EM) is thought to be mainly related to herpes infection and Stevens-Johnson syndrome (SJS) to drug reactions. AIMS To investigate this hypothesis in children, and to review our experience in the management of these patients. METHODS A retrospective analysis of 77 paediatric cases of EM or SJS admitted to the Children's Hospital in Bordeaux between ...

Invertebrates rely on an innate immune system to combat invading pathogens. The system is initiated in the presence of cell wall components from microbes like lipopolysaccharide (LPS), β-1,3-glucan (βG) and peptidoglycan (PG), altogether known as pathogen-associated molecular patterns (PAMPs), via a recognition of pattern recognition protein (PRP) or receptor (PRR) through complicated reactions...

The Expectation-Maximization (EM) algorithm is a general technique for maximum likelihood estimation (MLE). In this paper we present several of the important theoretical and practical issues associated with Gaussian mixture mod-eling (GMM) within the EM framework. First, we propose an EM algorithm for estimating the parameters of a special GMM structure, named a probablistic mapping network (PM...

The EM algorithm is widely used to develop iterative parameter estimation procedures for statistical models. In cases where these procedures strictly follow the EM formulation, the convergence properties of the estimation procedures are well understood. In some instances there are practical reasons to develop procedures that do not strictly fall within the EM framework. We study EM variants in ...
