background: the adjuvanticity potential of lactobacillus casei was first suggested in an old survey. the present study was designed to investigate the efficacy of a new immunotherapy against breast cancer made by mixing an extract of heated 4t1 mammary carcinoma cell line and a heat-killed preparation of lactobacillus casei. methods: female balb/c mice (6–8 weeks old, n=40) were challenged subc...

A channel model for line-of-sight (LoS) small street microcell in dense urban areas is proposed. The distribution of the scatterers in the channel seen from the receiver (Rx) based on the physical phenomenas is obtained. The coefficients of the distribution function is derived by approximation to a set of urban street microcell measurement data. The powerazimuth spectrum (PAS) for the proposed ...

This paper illustrates a new system for recovering clean speech signals from noisy acoustical environments using one microphone. At the beginning of this paper, we propose an assumption that the background noise is comprised of reverberant noise and direct-path noise. And a novel late reverberant spectral variance (LRSV) estimator is generated referring to this assumption, which can be used in ...

We develop a mathematical model for the spreading of a thin volatile liquid droplet on a uniformly heated surface. The model accounts for the effects of surface tension, evaporation, thermocapillarity, gravity and disjoining pressure for both perfectly wetting and partially wetting liquids. Previous studies of non-isothermal spreading did not include the effects of disjoining pressure and there...

A sensitivity analysis of heat transfers in an asymmetrically heated turbulent channel flow is performed using a dedicated transfer correlation. The investigated correlation developed to study the between fluid and wall gas-pressurized solar receivers concentrated power tower. working conditions correspond high-temperature levels high fluxes. Nusselt number depends on five parameters: Reynolds ...

We propose a probabilistic factorial sparse coder model for single channel source separation in the magnitude spectrogram domain. The mixture spectrogram is assumed to be the sum of the sources, which are assumed to be generated frame-wise as the output of sparse coders plus noise. For dictionary training we use an algorithm which can be described as non-negative matrix factorization with l spa...

We model behavior of a TCP-like source transmitting over a single channel to a server that processes work at constant rate r. Transmission by the source follows an on/oo mechanism. When the overall load in the system is below a critical constant , transmission rates increase linearly but when the load exceeds , then transmission rates decrease geometrically fast. We study the system by means of...

This study deals with forced convective heat transfer. It is divided into two parts. Firstly, a review of transfer involving convection in tubes and channels proposed. In the case channel geometry, studies dealing symmetrically asymmetrically heated flows as well one side are reported. Then, new correlation for associated turbulent flow developed using Large Eddy Simulations. The Proposed Corre...
