Linkage disequilibrium and haplotype block structure in six commercial pig lines
O sucesso de estudos de associação e, consequentemente, a seleção genômica dependem da densidade de marcadores utilizados nas análises, a qual, por sua vez, é determinada pela extensão do desequilíbrio de ligação (LD) ao longo do genoma. O LD é organizado em blocos de haplótipos, separados por hot …

Multi-Way Block Models
This dissertation investigates the Multi-Way Block Models proposed for mining inner structure of interaction between two sets of subjects. The Multi-Way Block Models generalize the Mixed Membership Stochastic Block Models (Airoldi et al., 2008) in multi-ways, as extensions in model settings …

Seismic vulnerability of historical structures with the discrete element method
It is widely recognized that historical structures represent a cultural heritage which should be preserved and transmitted to future generations. In several countries, and particularly, in the Mediterranean area, where a large number of important monuments are exposed to seismic hazard, there is a …

A structured reduced sequential quadratic programming and its application to a shape design problem
… the optimal design is reached. Furthermore, the block structure in the Jacobian of the linearized constraints is exploited by decomposing the variables into the design and flow parts. To achieve this, Sequential quadratic programming with BFGS update for the reduced Hessian of the Lagrangian …

Complexation Between DNA and Hydrophilic-Cationic Diblock Copolymers
… polycation architectures, hydrophilic-cationic diblock copolymers are particularly promising due to their versatility. Compared to the emphasis on biological evaluation of polyplexes, however, in-depth understanding of the polyplex formation process (and the parameters involved) is rather sparse. …

High-efficiency Waveguide Tunable Leaky-wave Antennas and Phase-shifters
… achieve a high radiation efficiency with a split-block structure. The concentration of the current distribution in the middle of the waveguide due to the proposed design results in reducing the Ohmic loss in the gap of the split-block antenna and maximizing its efficiency. The antenna has a much …
