Catching a Rat by Its Edglets

IEEE Transactions on Image Processing, 2013
Computer vision is a noninvasive method for monitoring laboratory animals. In this article, we propose a robust tracking method that is capable of extracting a rodent from a frame under uncontrolled normal laboratory conditions. The method consists of two steps. First, a sliding window combines three features to coarsely track the animal. Then, it uses

Prospective Control in Catching by Infants

Perception, 1994
Catching a moving object requires the ability to predict the future trajectory of the object. To test whether infants can use visual information predictively, reaching for a toy moving at different speeds was investigated in six infants around 11 months of age. The toy was occluded from view by a screen during the last part of its approach.

Catching a GEF by its tail

Trends in Cell Biology, 2007
The activation of Rho GTPases is mediated by guanine-nucleotide exchange factors (GEFs), which catalyze the exchange of GDP for GTP. Rho-GEFs are a very diverse family, with >70 members in humans. Bioinformatics analysis of the human Rho-GEFs shows that approximately 40% contain a putative PDZ-binding motif at the C-terminus.

Catching gravity, rolling by

Physics World, 2015
Nearly a century after Einstein predicted the existence of gravitational waves, the long effort to detect them directly is heating up. David Appell explains how a major upgrade at the Laser Interferometry Gravitational-wave Observatory may soon bring the hunt to a successful close.

Snow catch by Contier Crowns

Water Resources Research, 1967
Study of interception storage of snow by two species of sapling conifers in northern Idaho revealed that cumulative snow catch follows the classical law of autocatakinetic growth, orwhere Is, is interception storage, S is the interception storage capacity of the tree, e is the base of the natural logarithm, k is a constant expressing the rate of ...

By-Catch: Problems and Solutions

Marine Pollution Bulletin, 2000
Abstract By-catch is one of the most significant issues affecting fisheries management today. Incidental mortality of species which are long-lived and have low reproductive rates is a conservation problem affecting marine mammals, sea birds, sea turtles, sharks and other groups. By-catches can affect biodiversity through impacts on top predators, the

Acoustic orientation by fish‐catching bats

Journal of Experimental Zoology, 1965
AbstractCaptive Noctilio leporinus were unable to detect pieces of fish tissue or small air‐filled balloons mounted a few millimeters below the surface of the water. An up‐welling of water and small wires projecting vertically above the water surface were readily detected and dipped at, however.

Catching protein antigens by antibody affinity electrophoresis

ELECTROPHORESIS, 2004
AbstractA new kind of affinity electrophoresis called antibody affinity electrophoresis is a technique used to capture protein antigens based on their interactions with specific monoclonal or polyclonal antibodies incorporated in the polyacrylamide gel. Polyclonal anti‐glutathione‐S‐transferase (anti‐GST), monoclonal anti‐bovine serum albumin (anti‐BSA)
