the paper presents the results of an investigation on the acoustic performance of vertical profile parallel barriers with quadratic residue diffuser tops and faces. a 2d boundary element method (bem) was used to predict the barrier insertion loss. the results of rigid and with absorptive coverage were also calculated for comparisons. using qrd on the top surface and faces of all vertical profil...

Epidermal growth factor receptor (EGFR) signaling is instrumental for terminal differentiation of keratinocytes, hair morphogenesis, and maintenance of the skin barrier. Cheng et al. (2010) now demonstrate that the calcium-permeable channel TRPV3 is required for these EGFR-dependent functions.

Diffusion through semipermeable structures arises in a wide range of processes the physical and life sciences. Examples at microscopic level from artificial membranes for reverse osmosis to lipid bilayers regulating molecular transport biological cells chemical electrical gap junctions. There are also macroscopic analogs such as animal migration heterogeneous landscapes. It has recently been sh...
