1. Assessment of Covariance Selection Methods in High-Dimensional Gaussian Graphical Models
ABSTRACT The covariance selection in Gaussian graphical models consists in selecting, based on a sample of a multivariate normal vector, all those pairs of variables that are conditionally dependent given the remaining variables. This problem is equivalent to estimate the graph identifying the nonzero elements on the off-diagonal entries of the precision mat

2. Structural models for analysis of reinforced concrete frame buildings with masonry infills
Resumo Este trabalho tem como objetivo o estudo do comportamento de pórticos de edifícios de concreto armado preenchidos com alvenaria frente às ações horizontais, empregando-se dois modelos estruturais: i) modelo de diagonal equivalente (MDE) e ii) modelo com elementos finitos bidimensionais para estado plano de tensões (MEF). No primeiro modelo, a al

3. Estudo de pórticos preenchidos com alvenaria / Study Masonry Infilled Frame
O presente trabalho propõe realizar um estudo da arte sobre o comportamento de estruturas aporticadas preenchidas com painéis de alvenaria, para fim de contraventamento de edificações. Visa considerar o enrijecimento dessa alvenaria de preenchimento no pórtico para análise de ações horizontais, como a força do vento. O trabalho inicia-se com o desen

4. Physical Particle Representation and Generalized Transformation Theory
The investigation of the recently described generalized transformation theory which leads to a non-Hamiltonian description of dynamics is pursued. The concept of generalized unitary transformations of superoperators is introduced and a specific class of transformations studied. For nondissipative systems it is equivalent to the usual unitary transformations

5. The presence and absence of prosencephalic cell groups relaying striatal information to the medial and lateral thalamus in tenrec
Although there are remarkable differences regarding the output organization of basal ganglia between mammals and non-mammals, mammalian species with poorly differentiated brain have scarcely been investigated in this respect. The aim of the present study was to identify the pallidal neurons giving rise to thalamic projections in the Madagascar lesser hedgeho
