Soil is a major contributor to the biosphere–atmosphere exchange of carbonyl sulfide (COS) and carbon monoxide (CO). COS is [..1 ]a tracer to quantify terrestrial photosynthesis based on the [..2 ]coupled leaf uptake of COS and [..3 ]CO2, but [..4 ]such use requires separating soil COS flux[..5 ], which is unrelated to photosynthesis, from ecosystem COS uptake. For CO, soil is a [..6 ]significa...

The paper deals with the problem of convergence branched continued fractions two branches branching which are used to approximate ratios Horn's hypergeometric function $H_3(a,b;c;{\bf z})$. case real parameters $c\geq a\geq 0,$ b\geq $c\neq and complex variable ${\bf z}=(z_1,z_2)$ is considered. First, it proved fraction for z}\in G_{\bf h}$, where $G_{\bf h}$ two-dimensional disk. Using this r...

Este estudio evaluó el secuestro de carbono orgánico del suelo (COS) en cuatro coberturas vegetales (vegetación secundaria [VS], plantaciones forestales Eucalyptus globulus [EUC] y Pinus patula [PIN] pasturas [PAS]) su correlación con las propiedades fisicoquímicas suelo. Se tomaron muestras a dos profundidades horizonte A (0-10 10-20 cm). Igualmente, se midieron variables para evaluar relación...

A novel model for the regulation of cell excitability has recently been proposed. It originates from the observation that the background K(+) channel K2P1 (TWIK1) may be silenced by sumoylation in Xenopus oocytes and that inactivation of the putative sumoylation site (mutation K274E) gives rise to robust current expression in transfected COS-7 cells. Here, we show that only the mutation K274E, ...

Filiol and Fontaine recently proposed a family of stream ciphers named COS. COS is based on nonlinear feedback shift registers and was claimed to be highly secure. Babbage showed that COS (2, 128) Mode II is extremely weak. But Babbage’s attack is very expensive to break the COS (2, 128) Mode I (the complexity is around 2). In this paper, we show that the COS (2, 128) Mode I is very weak. Secre...

the aim of this study was to examine reality testing in schizophrenic children and compare it with normal children using minus responses subcomponent in ego impairment index of the rorschach test.in a descriptive design, 20 accidentally sampled children, including 10 schizophrenic and 10 normal children, were recruited in to two groups and were compared in terms of reality testing subcomponent ...

AIM Chitosan-oligosaccharides (COS) treatment showed lipid lowering effects in rats and reverse cholesterol transport (RCT) promotion in mice, suggested that COS might be a potential atheroprotective material. In this study, we investigated the effects of COS treatment on atherosclerosis (AS) in apolipoprotein E deficient mice (apoE-/-). METHODS After feeding high fat (HF) diet for 12 weeks w...

Here a coupled experimental and calculation technique for examination of thermal environments is presented. Its application to the extraction of geometric and thermal material parameters, calculation of thermal resistances etc., is demonstrated. The calculation tool is based on a Fourier-Galerkin approach and is applicable to rectangular 3-dimensional chips on substrates with several layers. Th...

This lecture covers the basics of core concepts in probability and statistics to be used in the course. These include random variables, continuous and discrete distributions, joint and conditional distributions, the chain rule, marginalization, Bayes Rule, independence and conditional independence, and expectation. Probability models are discussed along with the concepts of independently and id...

Last class, we discussed an analogue for Occam’s Razor for infinite hypothesis spaces that, in conjunction with VC-dimension, reduced the problem of finding a good PAClearning algorithm to the problem of computing the VC-dimension of a given hypothesis space. Recall that VC-dimesion is defined using the notion of a shattered set, i.e. a subset S of the domain such that ΠH(S) = 2 |S|. In this le...
