The spatially explicit insights into patterns of cropland change and in particular into hotspots of change derived from multiple methods provide useful information for decision-makers.”
“We first employ multi-scale time asymmetry (MSA) to analyze typical chaotic signals from Schuster maps and indicate that the MSA method can characterize the distinct time asymmetry of chaotic time series. Then we propose a modified MSA method, i.e., multi-scale weighted time asymmetry, and a novel time asymmetry index to investigate fractal Brownian motion signals and demonstrate its effects on discriminating between fractal signals with different Hurst exponents. Considering that the dynamic behavior of slug flow exhibits
chaotic features, we apply the MSA method to analyze experimental signals from a gas-liquid VX-770 research buy two-phase flow and find that slug flow presents a unique time asymmetric structure. In addition, we further explore the mechanism selleck kinase inhibitor leading to the formation of time asymmetry in terms of adaptive optimal kernel time-frequency representation. The results suggest that the MSA method can be a useful tool for detecting the complex flow structure underlying a gas-liquid two-phase flow.”
“The association of
arbuscular mycorrhizal fungi (AMF) with the roots of Lindenbergia philippensis (Cham.) Benth., sampled from a Zn-contaminated settling pond at a zinc smelter, significantly enhanced Zn accumulation (72,540 +/- A 5,092 mg kg(-1) dry weight) in rhizosphere sediment amended with 1,000 mg L-1 of Zn sulfate solution compared to fungicide-treatments that suppressed AMF colonization. This can be explained by a significant proportion of Zn being found in rectangular crystals that were associated with the root mucilaginous sheath. Despite this, all treatments maintained www.selleckchem.com/products/ly3039478.html the same Zn coordination geometry in both Zn oxidation state and the coordinated neighbouring atoms. X-ray absorption spectroscopy (XAS) showed a Zn(II) oxidation state as a
core atom and associated with six oxygen atoms symmetrically arranged in an octahedral coordination and coordinated with sulfur. The results may indicate a role for AMF in enhancing Zn immobilization in the rhizosphere of indigenous plants that successfully colonize Zn mining and smelting disposal sites.”
“Motivation: DOOSS (Data Overlaid On Secondary Structures) is a tool for visualizing annotated secondary structures of large single-stranded nucleotide sequences (such as full-length virus genomes). The purpose of this tool is to assist investigators in evaluating the biological relevance of secondary structures within particular sequences.”
“BACKGROUND: The AEBP1 (adipocyte enhancer binding protein) gene has two isoforms: AEBP1, the shorter of the two isoforms, and Aclp (aortic carboxypeptidase-like protein). Aclp-/- mice demonstrate a ventral wall defect that is similar to gastroschisis in humans.
