  • Recent approaches to text classi cation have used two di erent rst-order probabilistic models for classi cation, both of which make the naive Bayes assumption. Some use a multi-variate Bernoulli model, that is, a Bayesian Network with no dependencies between words and binary word features (e.g. Larkey and Croft 1996; Koller and Sahami 1997). Others use a multinomial model, that is, a uni-gram language model with integer word counts (e.g. Lewis and Gale 1994; Mitchell 1997).

  • In short, the literature still lacks a convincing test of the buffer-stock model. In this paper we use a survey question on precautionary wealth available in the 2002 Bank of Italy Survey on Household Income and Wealth (SHIW) to propose a direct test of buffer stock behavior. The question asks people how much savings they think they need for future emergencies, and is similar to a question contained in the 1995 and 1998 Surveys of Consumer Finances described in Kennickell and Lusardi (2004).

  • Cerebral cavernous malformations are common vascular lesions of the cen-tral nervous system that predispose to seizures, focal neurologic deficits and potentially fatal hemorrhagic stroke. Human genetic studies have iden-tified three genes associated with the disease and biochemical studies of these proteins have identified interaction partners and possible signaling pathways.

  • NFκB plays an important role in the immune system in all organisms. In this study, physicochemical properties and modelling of finfish NFκBIα protein was analysed using in silico approach. Finfish species: guppy (Poecilia reticulate), Bicolor damselfish (Stegastes partitus), Channel catfish (Ictalurus punctatus), Coelacanth (Latimeria chalumnae), and Australian ghostshark (Callorhinchus milii) were used in this study.

  • Soy proteins as plywood adhesives: formulation and characterization to develop and characterize formaldehyde free soybean wood adhesives with improved water resistance. Second order response surface regression models were used to determine the effects of soy protein isolate concentration, sodium chloride, and ph on adhesive performance.

  • The exit tunnel is modeled as a hollow cylinder attached to a flat wall, whereas a Go-like model is adopted for the proteins. Our results show that the exit tunnel has a strong effect on the folding mechanism by setting an order by which the secondary and tertiary structures are formed. For protein 1PGA, the folding follows two different folding routes. The presence of the tunnel also improves the foldability of protein.

  • Kremen-1 is a co-receptor of Wnt signaling, interacting with the Dkk-3 protein, which is an antagonist of the Wnt/β catenin pathway. In the present study we attempted to shed some light on the possible orientations of Kremen/Dkk-3 interactions, explaining the mechanisms of Kremen and Dkk-3 functions.

  • In this paper, we propose the use of monotonic answer set programming (L-ASP) to model protein interaction networks. We study these networks using monotonic answer set programming, all the information represent in a Boolean network and establish a general LASP frame work which describes the network semantics, then we use it to describe a particular case.

  • The theoretical manner in which periodontal disease progresses has long been a subject of debate. It is currently agreed that destructive periodontal disease progresses by means of asynchronous bursts of activity (Haffajee and Socransky 1986). According to this theory, periodontal tissue support is lost during short, acute episodes followed by prolonged periods of quiescence (Reddy, Palcanis, and Geurs 1997).

  • During the past two decades, reductionist biological science has generated new empirical data on the molecular foundations of biological structure and function at an accelerating rate. The list of organisms whose complete genomes have been sequenced is growing by the week. Annotations of these sequences are becoming more comprehensive, and databases of protein structure are growing at impressive, indeed formerly unimaginable rates.

  • ‘Professions’ have been subject to a variety of theoretical schema that attempt to identify their unique characteristics or traits: the features that can be regarded as the basis for the discrimination between forms of occupational organization and control that are professional and those that are not (Saks, 1983; Abbott, 1988). This elaboration of the essential traits of professions is more than a professional discourse.

  • In the Biomedical Applications of Biophysics, Volume 3 of the Handbook of Modern Biophysics, the authors have added to the topics introduced in Volume 1, Fundamental Concepts in Biophysics. These additional topics help trace the broad field of biophysics. Patrice Koehl starts the book with an introduction to protein structure prediction based on energetics, homology modeling, and ab-initio calculations. Dickey and Faller follow with a “how-to approach” to model biomembranes.

  • Our stylized model generates several empirical hypotheses about the insurance offer decision. Firms in industries where labor turnover rates are high do not tend to offer insurance. Premium rigidities will be most pronounced in such industries. Firms not offering insurance will tend to have lower health-cost variability and lower average expected health spending than firms offering insurance; for example, they have higher proportions of younger workers or are in industries where workers tend to be healthy.
