Admixture of evolutionary rates across a butterfly hybrid zone

Hybridization Bumper Cap is a major evolutionary force that can erode genetic differentiation between species, whereas reproductive isolation maintains such differentiation.In studying a hybrid zone between the swallowtail butterflies Papilio syfanius and Papilio maackii (Lepidoptera: Papilionidae), we made the unexpected discovery that genomic sub

Paths of interactive cracks in creep conditions

The paper contains plane strain analysis of uniformly stretched plate working in creep condition.The plate contains initial defects in forms of central and/or edge cracks working in mode I.These cracks are modelled by attributing critical value of damage parameter to preset points and therefore resulting in stresses set to zero (material does not s
