Bite marks are always unique because teeth are distinctive.Bite marks are often observed at the crime scene in sexual and in physical assault cases on the skin of the victims and sometimes on edible leftovers in burglary cases.This piece of evidence is often ignored, but if properly harvested and investigated, bite marks may prove useful in apprehe

Although the activity patterns of bats are recognized to vary widely, both, temporally and spatially, the underlying drivers for those patterns remain poorly understood.Presently, studies focusing on foraging bat ecology have only generalized activity and influence of the environment (across sampling periods, sampling nights, or seasons).The influe

Recent efforts have led to the development of extremely sophisticated methods for incorporating tree-wide data and accommodating uncertainty when estimating the temporal patterns of phylogenetic trees, but assignment of prior constraints on node age remains the most important factor.This depends largely on understanding substantive disagreements be

Tunnel invert uri ease paw gel for cats is a weak section of curved beam on tunnel foundation, and it is easy to break down.Based on the curved beam theory on elastic foundation, the curved beam model of tunnel invert was established, the displacement equation of tunnel invert under external load was deduced, and the formula of settlement of tunnel

In cognitive wireless multi-hop networks,the spectrum resources are highly variable and diverse.A cross-layer multi-channel MAC protocol combined with QoS search was proposed.The protocol combines the on-demand QoS search with dynamic spectrum allocation via cross-layer method,which only permits the transmission nodes to participate in the spectrum
