Pore network microfluidic models were fabricated by a silicon-on-glass technique that provides the precision advantage of dry etched silicon while creating a structure that is transparent across all microfluidic channels and pores, and can be imaged from either side. A silicon layer is bonded to an underlying borosilicate glass substrate and thinned to the(More)
pharyn geal teeth of H. sparsa most closely resemble those of Cambrian priapulids, whereas circumoral structures are also a key characteristic of Cambrian radiodontans. More crucially, H. sparsa is now regarded as an ancestor of living onychophorans (com­ monly known as velvet worms), so the find­ ing of H. sparsa mouthparts suggests that the absence of(More)
