In February 2004, American Family Physician (AFP), the Journal of the American Board of Family Practice (JABFP), and the Journal of Family Practice (JFP) will simultaneously publish an article titled “Strength of Recommendation Taxonomy (SORT): A Patient-centered Approach to Grading Evidence in the Medical Literature.” The purpose of the article is to present the SORT system, which was created ...

We present a dynamical model of processing and learning in the visual cortex, which reflects the anatomy of V1 cortical columns and properties of their neuronal receptive fields (RFs). The model is described by a set of coupled differential equations and learns by self-organizing the RFs of its computational units – sub-populations of excitatory neurons. If natural image patches are presented a...

Linear Independent Component Analysis considers the problem of nd-ing a linear transformation that makes the components of the output vector statistically independent. This can be applied to blind source separation, where the input data consist of unknown linear mixtures of unknown independent source signals. The original source signals can be recovered from their mixtures using the assumption ...

Over the past decade, Chinese local governments have adopted numerous innovations to address pressing social, economic, and environmental concerns. Realizing the limitations of unilateral actions, local governments increasingly rely on inter-local collaborations to address these issues at a regional level. Nevertheless, the theoretical and empirical study of regional collaborations in China has...

Primary care in western Europe is delivered by general practitioners (GPs) but their role within the overall health system is poorly understood. The aim of this article is to present an overview of the characteristics of general practice in the context of health systems and to describe their variability and interrelationships. Data were obtained from two main sources: publications of official o...

BACKGROUND Since the completion of three clinical trials indicating that voluntary medical male circumcision (VMMC) is an effective method to reduce men's chances of acquiring HIV, use of the procedure has been advocated in Kenya. Media messages shape popular understandings of the benefits and limitations of male circumcision. The objectives of this study were to (1) investigate promotion messa...

This paper describes a new neural architecture for unsupervised learning of a classi cation of mixed transient signals. This method is based on neural techniques for blind separation of sources and subspace methods. The feed-forward neural network dynamically builds and refreshes an acoustic events classication by detecting novelties, creating and deleting classes. A self-organization process a...

Abstract For treatment of severe malaria, the World Health Organization recommends 3 mg/kg intravenous artesunate in pediatric patients weighing less than 20 kg. Here we describe Food and Drug Administration’s rationale for selecting 2.4 kg based on literature review independent analyses.

the  main  assumptions  in  liner  mixed  model  are normality  and  independency  of  random  effect component.   unfortunately,   these   two  assumptions   might   be  unrealistic   in  some   situations. therefore, in this paper, we will discuss about the analysis of bayesian analysis of non-normal and non-independent mixed model using skew-normal/independent distributions, and finally, thi...

Let A1, . . . ,Ak be a collection of families of subsets of an n-element set. We say that this collection is cross-intersecting if for any i, j ∈ [k] with i = j, A ∈ Ai and B ∈ Aj implies A ∩ B = ∅. We consider a theorem of Hilton which gives a best possible upper bound on the sum of the cardinalities of uniform cross-intersecting families. We formulate a graphtheoretic analogue of Hilton’s cro...
