Observations of fast transport of fluorescent tracers in mouse brains have led to the hypothesis of bulk water flow directed from arterial to venous paravascular spaces (PVS) through the cortical interstitium. At the same time, there is evidence for interstitial solute transport by diffusion rather than by directed bulk fluid motion. It has been shown that the two views may be consolidated by i...

The antibacterial activity of immune haemolymph Galleria mellonella directed against Escherichia coli D31 was destroyed by Pseudomonas aeruginosa crude proteolytic fraction. This was demonstrated by diffusion well assay and acid gel electrophoresis and subsequent bioautography. On the contrary, lysozyme activity appeared to be insensitive to extracellular proteases of P. aeruginosa when activit...

Rectified transport of active ellipsoidal particles is numerically investigated in a two-dimensional asymmetric potential. The out-of-equilibrium condition for the active particle is an intrinsic property, which can break thermodynamical equilibrium and induce the directed transport. It is found that the perfect sphere particle can facilitate the rectification, while the needlelike particle des...

The Sensor Network consists of densely deployed sensor nodes. Energy optimization is one of the most important aspects of sensor application design. Data acquisition and aggregation techniques for processing data in-network should be energy efficient. Due to the cross-layer design, resource-limited and noisy nature of Wireless Sensor Networks(WSNs), it is challenging to study the performance of...

Different branching and annihilating random walk models are investigated by the cluster mean-field method and simulations in one and two dimensions. In the case of the A-->2A , 2A--> 0 model the cluster mean-field approximations show diffusion dependence in the phase diagram as was found recently by the nonperturbative renormalization group method [Phys. Rev. Lett. 92, 255703 (2004)]]. The same...

The paper addresses the problem of finding top k influential nodes in large scale directed social networks. We propose two new centrality measures, Diffusion Degree for independent cascade model of information diffusion and Maximum Influence Degree. Unlike other existing centrality measures, diffusion degree considers neighbors’ contributions in addition to the degree of a node. The measure als...

II. ENTEROCYTE ENTRY In brush-border membrane vesicles (BBMV) from rat small intestine the time course of T transport is not influenced by the presence or the absence of Nat(or Kt) in the incubation medium [1].At concentrations <1.25 ƒÊM, T is taken up mainly by a saturable mechanism (Km, 0.8, 0; Jmax, 0.35 pmol. mg-1 protein. 4 s-1), while at higher concentrations a passive diffusion prevails ...

objectives: goal-directed subsidies because of its nature can affect all aspects of iranian life. this scheme is not only an economic program but also affects other aspects of social life including: welfare and economic situation of society, labor market, income, expenditure and consumption pattern models of family and social problems such as poverty and inequality, drug abuse, family problem, ...

introduction: working in the complex and ever changing healthcare settings forces the nurses and nursing students to be equipped with lifelong learning skills. one of the lifelong learning skills is self-directed learning. this study aimed to explore the m.sc. nursing students’ self-directed learning activities. methods: a qualitative design using conventional content analysis approach was used...

the colorful paths and rainbow paths have been considered by severalauthors.a colorful directed path in a digraph $g$ is a directed path with $chi(g)$ vertices whose colors are different. a $v$-colorful directed path is such a directed path, starting from $v$. we prove that for a given $3$-regular triangle-free digraph $g$ determining whether there is a proper $chi(g)$-coloring of $g$such that ...
