In addition, we also show that our present solutions are valid for the problems of indentation by a rigid punch on an elastic half-space through a proper replacement of the contact radius and the corresponding material constant. Numerical results are provided to demonstrate the accuracy, applicability, and versatility of the developed solutions.

For the analysis of gene-environment (GxE) interactions commonly single nucleotide polymorphisms (SNPs) are used to characterize genetic susceptibility, an approach that mostly lacks power and has poor reproducibility. One promising approach to overcome this problem might be the use of weighted genetic risk scores (GRS), which are defined as weighted sums of risk alleles of gene variants. The gold-standard is to use external weights from published meta-analyses.

Visco-elastic damping is one of the passive control methods in structural vibration. Multilayer visco-elastic patch is preferred due to high level of damping and easy implementation. In order to obtain an economical design, many objectives must be considered and this concept leads to solving multi-objective optimization problem.

This paper deals with the reflection and transmission of P-waves at a very rough interface between two isotropic elastic solids. The interface is assumed to oscillate between two straight lines. By mean of homogenization, this problem is reduced to the reflection and transmission of P-waves through an inhomogeneous orthotropic elastic layer.
