Introduction: The ultimate goal of radiation treatment planning is to yield a high tumor control probability (TCP) with a low normal tissue complication probability (NTCP). Historically  dose volume histogram (DVH) with only volumetric dose distribution was utilized as a popular tool for plan evaluation  hence present study aimed to compare the radiobiological effectiveness of the cobalt-60 (Co...

the aim of this study was to investigate the mechanical properties (flexural strength, micro-shear bond strength) and remineralizing potential of fissure sealants by adding various concentrations of β-tricalcium phosphate nanoparticles.this in-vitro study consisted of five experimental groups containing prepared nano-fisssure sealants (1-5 wt.% β-tcp nanoparticles) and two control groups contai...

It is well known that TCP does not fully utilize the available bandwidth in fast long-distance networks. To solve this scalability problem, several high speed transport protocols have been proposed. They include HighSpeed TCP (HS-TCP), Scalable TCP (S-TCP), Binary increase control TCP (BIC-TCP), and H-TCP. These protocols increase (decrease) their window size more aggressively (slowly) compared...

We show that the Lukierski et al. model, invariant with respect to the two-fold centrally extended Galilei group, can be decomposed into an infinite number of independent copies (differing in their spin) of the “exotic” particle of Duval et al. The difference between the two models is found to be sensitive to electromagnetic coupling. The nature of the noncommutative plane coordinates is discus...

The model invariant with respect to the two-fold centrally extended Galilei group proposed by Lukierski et al. can be decomposed into an infinite number of independent copies (differing in their spin) of the “exotic” particle of Duval et al. Interpreted as describing a non-relativistic anyon, this model is the non-relativistic limit of a particle with torsion related to relativistic anyons. As ...

TCP Reno congestion control carries two issues. First, its performance is poor in high-speed networks. To solve this TCP Reno drawback, HighSpeed TCP and Scalable TCP were proposed. However, the fairness between these proposed TCP and TCP Reno is not considered, when both connections coexist. Second, TCP Reno connections share bandwidth unfairly, when TCP flows with different RTTs use the same ...

Transmission control protocol (TCP) provides reliable transport services for Internet applications. Broadband geostationary earth orbit (GEO) satellite networks play an important role in providing Internet access and network connectivity. They are characterized by long propagation delays and high bit error rates, which negatively affect TCP performance. We proposed a modification of TCP named T...
