The complex patterns observed in experiments on suspensions of swimming cells undergoing bioconvection have fascinated biologists, physicists and mathematicians alike for over a century. Theoretical models developed over the last few decades have shown a strong similarity with Rayleigh–Bénard thermal convection, albeit with a richer dynamical behaviour due to the orientational degrees of freedo...

Not similar with the current interest on collaboration networks research, the focus in this paper is competition networks. The topology of a firm competition network has been investigated empirically and theoretically. We have found that four fundamental characteristics emerge simultaneously in the competition network, including hierarchical modularity, positive degree correlation, power-law de...

Current technology dictates that parallel processing is required to perform real-time volume rendering for any signi cant data set sizes and image qualities. This paper compares parallel architectures and algorithms which perform volume rendering, as well as a few alternative architectures not previously applied to the volume rendering problem. Since the memory to processor bandwidth is the maj...

Four visual lexical decision experiments using the masked priming paradigm tested for effects of prime word frequency and cumulative root frequency with primes varying in degree of morphological and orthographic overlap with free root targets in French. Experiments 1 and 3 showed that only high frequency morphologically related primes produce signiŽcantly faster response times compared to ortho...

Let $L = U_3(9)$ be the simple projective unitary group in dimension 3 over a field  with 92 elements. In this article, we classify groups with the same order and degree pattern as an almost simple group related to $L$. Since $Aut(L)equiv Z_4$ hence almost simple groups related to $L$ are $L$, $L : 2$ or $L : 4$. In fact, we prove that $L$, $L : 2$ and $L : 4$ are OD-characterizable.

recognizing of river flow pattern, deposition and erosion areas in meanders is highly important. despite the limitations of the physical models in laboratory investigation of flow pattern in meanders, mathematical models can be helpful. in this research, rsm and les turbulence models have been compared on sharp river bend of a laboratory flume using fluent software. the laboratory flume is a sh...

BACKGROUND AND OBJECTIVES This study was designed to assess the characteristics of patients according to the degree and audiogram shape of hearing loss and the association of these characteristics with hearing aids (HA) choice, return rate, and cause of return. SUBJECTS AND METHODS This study included 460 individuals who received HAs from 2011 to 2015. The relationships between type of HA and...
