The selective coefficients that keep modifying genes in a population.
A gene’s effects on fitness can be determined only if it produces a distinct phenotype of a known polymorphism. It is then possible to measure the phenotype’s chances of survival against other phenotypes, as, for example, did CLARKE and SHEPPARD (1966) for the melanic and non-melanic forms of the moth Biston betularia. But if a character can take any value in a continuous range, there is often ...
متن کاملNeurons that keep a straight face.
Recognizing a person we know seems like an unremarkable occurrence within the stream of everyday events. However, the ease with which most of us recognize a familiar face belies the daunting complexity of the underlying computational challenges—challenges that become apparent in the not so rare cases of face-blindness and in attempts to develop computational models that mimic human face recogni...
متن کاملQuantum fingerprints that keep secrets
We introduce a new type of cryptographic primitive that we call hiding fingerprinting. A (quantum) fingerprinting scheme translates a binary string of length n to d (qu)bits, typically d ≪ n, such that given any string y and a fingerprint of x, one can decide with high accuracy whether x = y. Classical fingerprinting schemes cannot hide information very well: a classical fingerprint of x that g...

15 صفحه اولPrevalence of Genes Encoding Aminoglycoside Modifying Enzymes in Clinical Isolates of Klebsiella Pneumoniae in the Hospitals of Borujerd
Background and Aims: Given the importance of aminoglycoside resistance in nosocomial and community infections caused by bacterial pathogenes such as Klebsiella pneumoniae (K. pneumoniae), the aim of this study was to determine the frequency of aac (6')- Ib and aac (3)- IIa, the genes encoding aminoglycoside modifying enzymes involved in aminoglycoside resistance. Material and Methods: A t...
