The Hopf bifurcation curves for the averaged system of second order differential equations are obtained using an analytical method. Numerical experiments have proved the existence of chaotic motion in the vicinity of these curves. For the different parameter sets, two very similar types of evolution ...
In the realm of medical interventions, the evolution of balloon catheters has been instrumental in revolutionizing minimally invasive procedures. As versatile tools used in various medical specialties, balloon catheters come in two primary types, each tailored to address specific clinical needs. This ...
epigenomic and gene expression resources for future research on evolution and functional genomics inPleurotusand related genera as well as on more efficient breeding of improved edible mushroom cultivars.
摘要: Studies the evolution of two experimental populations of the fruit fly species Drosophila melanogaster that are infected with a rhabdovirus, sigma. Absence of P allele that is restrictive of viral multiplication; Selection of type II viral type over type I in the absence of the P allele....
(Methods). We find that there has most probably been only one evolution of flight muscle asynchrony at the order level. There is an 86% probability that a single transition from synchronous to asynchronous flight in the ancestor of the clade of Thysanoptera, Hemiptera, Psocodea and holometabo...
Volcanic tremor provides clues to magma migration pathways so that tremor source location is expected to be an efficient tool for tracking dynamic behavior of magma in evolution of eruptive activity. However, clear evidence, which connects between temporal variation in volcanic tremor and evolution of...

The expression of max was concomitant with CAM2 expression, but not with CAM1. It has been reported that MYC/MAX heterodimer as a regulator of gene expression has been maintained throughout vertebrate evolution, and the expression of c-myc has been concomitant with max expression. In addition,...
evolution such as genome size reduction, functional losses associated with reduced metabolism, and adaptive functional gains linked to parasite virulence5. Most models of parasite coevolution are limited to interactions between single focal parasites and their hosts, in part because multispecies dynamics ...
The evolution of the VDR expression pattern is, however, less clear. The VDR transcripts are known to be fairly ubiquitous in lamprey, teleost, and frog adult tissues analyzed by RT-PCR or Northern blot [37]. Because few studies have described the spatio-temporal expression pattern of VDR ...
