Current Biology, 1998 Given the present obsession with pattern formation, it is hard to appreciate that 30 years ago there were but few eccentrics who knew what the words meant. In those days, any who tried to understand patterns searched throughout zoology and botany for colleagues who shared their interest.

Developmental Status: Impact of Short-Term Ischemia on Follicular Survival of Whole Ovarian Transplantation in a Rabbit Model. [PDF]
PLoS ONE, 2015 Ischemia is the first mechanism that provokes the loss of follicles in ovarian grafts over the long term. In whole ovarian transplantation, it remains unknown, however, how changes in follicular development are influenced by short-term ischemia.

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2010 The patch transform represents an image as a bag of overlapping patches sampled on a regular grid. This representation allows users to manipulate images in the patch domain, which then seeds the inverse patch transform to synthesize modified images. Possible modifications include the spatial locations of patches, the size of the output image, or the ...

Predictive Modeling of High Temperature Performance of SMA-13 Cold Patch Asphalt Mixture Based on Fractal Theory [PDF]
E3S Web of ConferencesIn order to study the relationship between the high temperature performance of cold-patched asphalt mixtures and gradation fractal, 13 groups of SMA-13 asphalt mixtures were designed, and high temperature rutting test was carried out to study the high ...

Protecting your software updates [PDF]
, 2013 As described in many blog posts and the scientific literature, exploits for software vulnerabilities are often engineered on the basis of patches, which often involves the manual or automated identification of vulnerable code.
