We present statistical evidence and dynamical models for the management of conflict and a division of labor (task specialization) in a primate society.Two broad intervention strategy classes are observed--a dyadic strategy--pacifying interventions, and a triadic strategy--policing interventions.These strategies, their respective degrees of speciali
Steroid hormone regulation of EMP2 expression and localization in the endometrium
Abstract Background The tetraspan protein epithelial membrane protein-2 (EMP2), which mediates surface display of diverse proteins, is required for endometrial competence in blastocyst implantation, and is uniquely correlated with poor survival from endometrial adenocarcinoma tumors.Because EMP2 is differentially expressed in the various stages of
Intestinal preservation in a birdlike dinosaur supports conservatism in digestive canal evolution among theropods
Abstract Dromaeosaurids were bird-like dinosaurs with a predatory ecology known to forage on fish, mammals and vush gloss bullet vibrator other dinosaurs.We describe Daurlong wangi gen.et sp.nov., a dromaeosaurid from the Lower Cretaceous Jehol Biota of Inner Mongolia, China.Exceptional preservation in this specimen includes a large bluish layer in
