the broad consumption of antibiotics such as fluoroquinolones and the genetic adaption of opportunistic pathogenic bacteria including pseudomonas aeruginosa , has led to develop of floroquinolone-resistant strains of pseudomonas aeruginosa . thus, the aim of the present study is to reveal the types of hot spot mutations occurring in selected dna gyrase subunit a gene in fluoroquinolone-resistan...

In this paper we consider a Wi-Fi hot spot were M users are performing TCP downloads from Internet remote servers. Our study focuses on characterizing the way the TCP flow control mechanisms affect the MAC protocol operations, and identifying the main causes of the throughput limitations shown by the TCP traffic. In particular, we show that the TCP throughput is not limited by the collision eve...

It has been observed that AU-rich sequences form homologous recombination hot spots in brome mosaic virus (BMV), a tripartite positive-stranded RNA virus of plants (P. D. Nagy and J. J. Bujarski, J. Virol. 71:3799-3810, 1997). To study the effect of GC-rich sequences on the recombination hot spots, we inserted 30-nucleotide-long GC-rich sequences downstream of AU-rich homologous recombination h...

Shared bu€er switches do not su€er from head of line blocking which is a common problem in simple input bu€ering. Shared bu€er switches have previously been studied under uniform and unbalanced trac patterns. However, due to the complexity of the model, it was not possible to fully explore the performance of such a switch, in the presence of a single hot spot. In this paper, we develop a new m...

Relations between stagnation and in-flight phases are derived both analytically and numerically, for hydrodynamic variables relevant to direct-drive inertial confinement fusion implosions. Scaling laws are derived for the stagnation values of the shell density and areal density; also the hot spot pressure, temperature and areal density. Simple formulas are derived for the thermonuclear energy g...

Simulations of electron transport are carried out by solving the Fokker-Planck equation in the diffusive approximation. The system of a single laser hot spot, with open boundary conditions, is systematically studied by performing a scan over a wide range of the two relevant parameters: (1) Ratio of the stopping length over the width of the hot spot. (2) Relative importance of the heating throug...

Multistage Interconnection Networks based on shared buuering are known to have better performance and buuer utilization than input or output buuered switches. Shared buuer switches do not suuer from head of line blocking which is a common problem in simple input buuering. Shared buuer switches have previously been studied under uniform and unbalanced traac patterns. However, due to the complexi...
