To identify various P2P flows accurately in real-time,a hidden Markov model(HMM)based P2P flow identification technique was proposed.This approach made use of packet size,inter-arrival time and arrival order to construct flow identification model,in which discrete random variable was used to depict the characteristics of HMM state.A framework calle
A stochastic continuous-time Markov chain tuberculosis model with fast-slow progression and relapse is established to explore the impact of the demographic variation on TB transmission.At first, the extinction threshold and probability of the disease extinction and outbreak are obtained by applying the multitype Galton-Waston branching process for
Hundreds of tRNA genes and pseudogenes are encoded by the human genome.tRNAs are the second most abundant type of RNA in the cell.Advancement in deep-sequencing technologies have revealed the presence Cuticle Cream of abundant expression of functional tRNA-derived RNA fragments (tRFs).They are either generated from precursor (pre-)tRNA or mature tR
One approach to improve the aerodynamic performance of airfoils and hydrofoils is inject a small amount of energy to the system (such as fluid injection or suction on the surface), to change the lift and drag.In fact, surface suction and blowing of the fluid can Cuticle Cream improve the pressure distribution and velocity gradient on the airfoil/hy
