Catch curves have been used to estimate survival and instantaneous mortality for fish and wildlife populations for many years. In order to better analyze catch curve data from the Apostle Islands population lake trout Salvelinus namaycush in Lake Superior, we develop a Bayesian approach to catch curve analysis. First, the proposed Bayesian approach is illustrated for a single catch curve and th...

Catch-bonds refer to the counterintuitive notion that the average lifetime of a bond has a maximum at a nonzero applied force. They have been found in several ligand-receptor pairs and their origin is still a topic of debate. Here, we use coarse-grained simulations and kinetic theory to demonstrate that a multimeric protein, with self-interacting domain pairs, can display catch-bond behavior. O...

Perhaps the most fundamental insight from fishery science is that ecosystems impose important and predictable constraints on food production from the sea. The familiar hump-shaped growth curve implies that the growth rate and carrying capacity of a species limit its production: Once stocks are depleted, further increasing fishing pressure will only lead to decreases in catch. This logic underpi...

Small minerals make strong bones Selectins with a catch ot content simply with a good fit, evolution has apparently designed adhesion molecules that stick optimally only when tugged upon. This property, may stop leukocytes and platelets from lingering in stagnant backwaters in the blood where there is little or no flow. Blood is a medium dominated by flow and shear forces. " If you think flow i...

Recent studies of actomyosin-ring assembly in fission yeast have suggested that an intricate web of membrane-bound nodes containing myosin and the actin nucleator formin is pulled together into a tight ring through a 'search-and-capture' mechanism.

The appropriateness of paraphrases for words depends often on context: “grab” can replace “catch” in “catch a ball”, but not in “catch a cold”. Structured Vector Space (SVS) (Erk and Padó, 2008) is a model that computes word meaning in context in order to assess the appropriateness of such paraphrases. This paper investigates “best-practice” parameter settings for SVS, and it presents a method ...
