Effect of Ni and Ni-coated Carbon Nanotubes on the interfacial reaction and growth behavior of Sn58Bi/Cu intermetallic compound layers
The interface reactions between Cu and Sn58Bi solder doped with mass fraction of 0.5 % Ni, 1 % Ni, 0.5 % Ni-CNTs and 1 % Ni-CNTs after reflow and solid-state aging were studied. Results show that the Ni and Ni...

Correcting for biases in affected sib-pair linkage analysis caused by uncertainty in sibling relationship
When there is uncertainty in sibling relationship, the classical affected sib-pair (ASP) linkage tests may be severely biased. This can happen, for example, if some of the half sib-pairs are mixed with full si...

A two-phase procedure for QTL mapping with regression models
It is typical in QTL mapping experiments that the number of markers under investigation is large. This poses a challenge to commonly used regression models since the number of feature variables is usually much...

Random weighting method for Cox’s proportional hazards model
Variance of parameter estimate in Cox’s proportional hazards model is based on asymptotic variance. When sample size is small, variance can be estimated by bootstrap method. However, if censoring rate in a sur...
