TL;DR: It is hypothesized that the regulation of self and non-self fungal cell wall degradation is not due to a speciation of individual chitinases, but is regulated by substrate accessibility due to cell wall protection in healthy hyphae vs deprotection during mycoparasitic attack, hyphal ageing and autolysis.
Abstract: Lysis of the prey’s cell wall is one of the key steps during mycoparasitism. Genome analysis of two mycoparasitic Trichoderma species, T. atroviride and T. virens, revealed an expanded arsenal of genes encoding enzymes potentially involved in cell wall hydrolysis. Glycoside hydrolase family 18, which contains all fungal chitinases, is the largest family of carbohydrate-active enzymes in mycoparasitic Trichoderma species. However, in addition to their aggressive functions during mycoparasitism, the roles of chitinases and other cell wall degrading enzymes also include remodelling and recycling of the fungus’s own cell wall. In this review we discuss current knowledge about fungal cell wall degrading enzymes in Trichoderma and how the fungus distinguishes between self- and non-self fungal cell wall degradation. In the past few years, the chitinolytic enzyme machinery of Trichoderma has been used as a model system to address this question. Gene expression profiles of most investigated chitinases indicate an overlap of functions of the respective enzymes and an involvement in both self- and non-self fungal cell wall degradation. Similar sets of enzymes appear to be involved in mycoparasitism, exogenous chitin decomposition and recycling of the fungus’s own cell wall. Thus, we hypothesize that the regulation of self and non-self fungal cell wall degradation is not due to a speciation of individual chitinases. Rather, we hypothesize that it is regulated by substrate accessibility due to cell wall protection in healthy hyphae vs deprotection during mycoparasitic attack, hyphal ageing and autolysis.

TL;DR: The approach allows for partial visibility of workflows and their resources, thus providing powerful ways for inter-organizational workflow configuration, and provides workflow participants with the freedom to change their work-flows without changing their roles in the cooperation.
Abstract: This paper presents a novel approach to inter-organizational workflow cooperation. Our goal is to provide support for organizations which are involved in a shared but not pre-modeled cooperative workflow across organizational boundaries. Our approach allows for partial visibility of workflows and their resources, thus providing powerful ways for inter-organizational workflow configuration. Varying degrees of visibility of workflows enable organizations to retain required levels of privacy and security of internal workflows. Our presented view concept provides a high degree of flexibility for participating organizations, since internal structures of collaborative workflows may be adapted without changes in the inter-organizational workflows. Furthermore, we provide workflow participants with the freedom to change their work-flows without changing their roles in the cooperation. This increases flexibility and is an important step to increase efficiency as well as reduction in costs for inter-organizational workflows. The presented approach is inspired by the Service-oriented Architecture (SOA). Accordingly, our approach consists of three steps: workflow advertisement, workflow interconnection, and workflow cooperation.

TL;DR: In this article, a measurement of the single-top-quark t-channel production cross section in pp collisions at s√=7 TeV with the CMS detector at the LHC is presented.
Abstract: A measurement of the single-top-quark t-channel production cross section in pp collisions at s√=7 TeV with the CMS detector at the LHC is presented. Two different and complementary approaches have been followed. The first approach exploits the distributions of the pseudorapidity of the recoil jet and reconstructed top-quark mass using background estimates determined from control samples in data. The second approach is based on multivariate analysis techniques that probe the compatibility of the candidate events with the signal. Data have been collected for the muon and electron final states, corresponding to integrated luminosities of 1.17 and 1.56 fb^(−1), respectively. The single-top-quark production cross section in the t-channel is measured to be 67.2±6.1 pb, in agreement with the approximate next-to-next-to-leading-order standard model prediction. Using the standard model electroweak couplings, the CKM matrix element |V_(tb)| is measured to be 1.020 ± 0.046 (meas.) ± 0.017 (theor.).
