Based on fractal theory, the fractal characteristics of soil particle size distribution (PSD) and soil water retention curve (WRC) under the five vegetation types were studied in the mountainous land of Northern China. Results showed that: (1) the fractal parameters of soil PSD and soil WRC varied greatly under each different vegetation type, with Quercus acutissima Carr. and Robina pseudoacaci...

The PDZ domains of postsynaptic density (PSD) protein-95 play a role in the localization of PSD-95 and binding partners to neuronal synapses. The identification of binding partners to these PDZ domains can help us in understanding how signalling complexes are assembled. We observed that one of the subunits in the sec6/8 or exocyst complex, sec8, contains a C-terminal consensus sequence for PDZ ...

This paper considers the problem of positive semidefinite factorization (PSD factorization), a generalization of exact nonnegative matrix factorization. Given an m-by-n nonnegative matrix X and an integer k, the PSD factorization problem consists in finding, if possible, symmetric k-by-k positive semidefinite matrices {A, ..., A} and {B, ..., B} such that Xi,j = trace(AB) for i = 1, ...,m, and ...

Quinoa kernels are generally whole-milled due to their small kernel size. However, roller milling allows the separation of starchy perisperm from protein- and fat-rich bran fraction. Both fractions can be used for specific food applications. Studies have focused on quinoa but information tempering is rather limited. This study investigates impact different conditions quinoa. Three types commerc...

IRSp53 (BAIAP2) is an abundant protein at the postsynaptic density (PSD) that binds to major PSD scaffolds, PSD-95 and Shanks, as well as to F-actin. The distribution of IRSp53 at the PSD in cultured hippocampal neurons was examined under basal and excitatory conditions by immuno-electron microscopy. Under basal conditions, label for IRSp53 is concentrated at the PSD. Upon depolarization by app...

PDZ-domain-containing proteins such as PSD-95 have been implicated in the targeting and clustering of membrane proteins. Biochemical and immunohistochemical studies indicate that PSD-95 recognizes COOH-terminal S/TXV sequences present in Kv1 K+ channels. However, the effect of binding a PDZ domain on a target protein has not been studied in live cells. In the present study, a green fluorescent ...

The aim of this contribution is a survey of different nucleation and growth kinetics terms effects on modeling results of KNO3 Continuous Mixed Suspension Mixed Product Removal (CMSMPR) crystallizer. By studying the four different states in modeling, results show that, although these terms for similar crystallization system and operating conditions are similar, there is very different dynamic b...

Numerical modeling of non-inertial particles dynamics is usually addressed by solving a population balance equation (PBE). In addition to space and time, discretization required also in the particle-size space, covering large range variation controlled strongly nonlinear phenomena. A novel approach presented which hybrid stochastic/fixed-sectional method PBE used train combination an artificial...

The rheological properties of blended cement-based materials depend strongly on mixture proportions and the characteristics of the components. In this study, design of experiments is used to investigate the influence of three variables (cement particle size distribution (PSD), fly ash PSD, and ratio of fly ash to cement) at each of four levels on the yield stress and viscosity of blended pastes...
