G. P. Bingham and M. Lind (2008, Large continuous perspective transformations are necessary and sufficient for accurate perception of metric shape, Perception & Psychophysics, Vol. 70, pp. 524-540) showed that observers could perceive metric shape, given perspective changes ≥ 45° relative to a principal axis of elliptical cylinders. In this article, we tested (a) arbitrary perspective changes o...

Conventional pressure sensitive adhesives (PSAs) are fabricated from soft viscoelastic materials that satisfy Dahlquist's criterion for tack with a Young's modulus (E) of 100 kPa or less at room temperature and 1 Hz. In contrast, the adhesive on the toes of geckos is made of beta-keratin, a stiff material with E at least four orders of magnitude greater than the upper limit of Dahlquist's crite...

CPCs are a relatively common finding during the second trimester sonography. when a choroid plexus cyst is identified, the presence of structural malformation and other sonographic markers of aneuploidy should be assessed with a detailed fetal anatomic survey performed by an experienced person. if no other sonographic abnormalities are present, the CPC is considered isolated. given the consider...
