Captivity selects for smaller eyes

Captivity selects for smaller eyes

combination of kinetic proofreading and induced fit in tRNA selection provides a suitable balance between fidelity and rapid elongation rates. If we take the simplest case of kinetic proofreading, where there are no differences in forward rate constants introduced by induced fit — where k 3 and k 5 are equivalent for both cognate and near-cognate tRNAs — significant discrimination between cogna...

Eavesdropping selects for conspicuous signals

Animal communication signals generally evolve to become increasingly conspicuous for intended receivers [1]. However, such conspicuous signals are also more susceptible to eavesdropping, i.e. exploitation by unintended receivers [2]. It is typically thought that eavesdroppers harm signalers and select against conspicuous signals [3]. But, if signal conspicuousness deters eavesdroppers by indica...

Captivity for Conservation? Zoos at a Crossroads

How Computer Selects Antecedent?

1. Introduction This study provides a computer-simulated optimal selection of antecedent of reflexive pronouns based on the Visual C++ computer programming language. The algorithm that I use for this implementation is based on the optimal theoretic approach to the proper interpretation of reflexive pronoun roughly adopted in Moon (1999). I show that the complex behavior of reflexive pronouns ca...

Irradiation Selects for p53-Deficient Hematopoietic Progenitors

Identification and characterization of mutations that drive cancer evolution constitute a major focus of cancer research. Consequently, dominant paradigms attribute the tumorigenic effects of carcinogens in general and ionizing radiation in particular to their direct mutagenic action on genetic loci encoding oncogenes and tumor suppressor genes. However, the effects of irradiation are not limit...
