(1996). We also extend the M tests developed in Perron and Ng (1996) to allow for GLS detrending of the data. The MIC along with GLS detrended data yield a set of tests with desirable size and power properties.

We consider the problem of approximating a given m * n matrix A by another matrix of specified rank k, which is smaller than m and n. The Singular Value Decomposition (SVD) can be used to find the "best " such approximation. However, it takes time polynomial in m, n which

... matrix A. It is often of interest to find a low-rank approximation to A, i.e., an approximation D to the matrix A of rank not greater than a specified rank k, where k is much smaller than m and n. Methods such as the Singular Value Decomposition (SVD) may be used to find an approximation

, since imprecisions in the data often lead to a large number of answers of low quality, and users are interested only in the answers with the highest probabilities. The idea in our algorithm is to run in parallel several Monte-Carlo simulations, one for each candidate answer, and approximate each

The main technique used in algorithm design for approximating #P-hard counting problems is the Markov chain Monte Carlo method. At the heart of the method is the study of the convergence (mixing) rates of particular Markov chains of interest. In this paper we illustrate a new approach

Validation of a treadmill six-minute walk test protocol for the evaluation of patients with pulmonary arterial hypertension* Validação de um protocolo para o teste de caminhada de seis minutos em esteira para avaliação de pacientes com hipertensão arterial pulmonar

are simulated from a realistic biological network involving DNAs, mRNAs, inactive protein monomers and active protein dimers. Then, interaction networks are inferred from these data in a reverse engineering approach, using Bayesian networks and Bayesian learning with Markov chain Monte Carlo. Results

Mycoplasmas were searched in the ear canal flushing of 60 bovine in Brazil. The prevalence obtained was 80%. The percentages of typified species were 12.5%, for M. alkalenses; 2.1%, M. arginini; 8.35%, M.

Antifungal effect of electrospun nanofibers containing cetylpyridinium chloride against Candida albicans Abstract: It is known that cetylpyridinium chloride (CPC) has in vitro and in vivo antifungal action against Candida albicans, with advantages over other common antiseptics. A CPC delivery

The graded reflection equation is investigated for the Uq[osp(r|2m) (1)] vertex model. We have found four classes of diagonal solutions with at the most one free parameter and twelve classes of non-diagonal ones with the number of free parameters depending on the number of bosonic (r) and fermionic
