Abstract Plant movements for survival are nontrivial.Antheridia in the moss Physcomitrium patens (P.patens) use motion to eject sperm in the presence of water.However, the biological and mechanical mechanisms that actuate the process are unknown.Here, the burst of the antheridium of P.patens, triggered by water, results from elastic instability and
Abstract The phenomenon of bifurcation in disease transmission models has been observed in a number of epidemiological models.The consequence of bifurcation is that the classical requirement of the reproduction number being less than unity becomes only a necessary, but not sufficient, for disease elimination.This paper addresses the problem of find

Abstract Extracellular vesicles (EVs) are nanosized heat-stable vesicles released by virtually all cells in the body, including tumor cells and tumor-infiltrating dendritic cells (DCs).By carrying molecules from originating cells, EVs work as cell-to-cell communicators in both homeostasis and cancer but may also represent valuable therapeutic and d
The history of mudbrick production and construction in the southern Levant may be dated as far back to the Pre-Pottery Neolithic A.However, at many of the sites where mudbrick remains were noted, their preservation was poor, so investigation of their production and the related construction techniques in antiquity was precluded.The 7,200 year old (c
