TL;DR: A high level of biodiversity among MRSA, especially among strains harbouring SCCmec IV and V elements is shown, and the data indicate a high rate of genetic recombination in MRSA involving SCC elements, bacteriophages or other mobile genetic elements and large-scale chromosomal replacements.
Abstract: In recent years, methicillin-resistant Staphylococcus aureus (MRSA) have become a truly global challenge. In addition to the long-known healthcare-associated clones, novel strains have also emerged outside of the hospital settings, in the community as well as in livestock. The emergence and spread of virulent clones expressing Panton-Valentine leukocidin (PVL) is an additional cause for concern. In order to provide an overview of pandemic, epidemic and sporadic strains, more than 3,000 clinical and veterinary isolates of MRSA mainly from Germany, the United Kingdom, Ireland, France, Malta, Abu Dhabi, Hong Kong, Australia, Trinidad & Tobago as well as some reference strains from the United States have been genotyped by DNA microarray analysis. This technique allowed the assignment of the MRSA isolates to 34 distinct lineages which can be clearly defined based on non-mobile genes. The results were in accordance with data from multilocus sequence typing. More than 100 different strains were distinguished based on affiliation to these lineages, SCCmec type and the presence or absence of PVL. These strains are described here mainly with regard to clinically relevant antimicrobial resistance- and virulence-associated markers, but also in relation to epidemiology and geographic distribution. The findings of the study show a high level of biodiversity among MRSA, especially among strains harbouring SCCmec IV and V elements. The data also indicate a high rate of genetic recombination in MRSA involving SCC elements, bacteriophages or other mobile genetic elements and large-scale chromosomal replacements.

TL;DR: In this article, it was shown that the energy levels of lead sulfide QDs, measured by ultraviolet photoelectron spectroscopy, shift by up to 0.9 eV between different chemical ligand treatments.
Abstract: The electronic properties of colloidal quantum dots (QDs) are critically dependent on both QD size and surface chemistry. Modification of quantum confinement provides control of the QD bandgap, while ligand-induced surface dipoles present a hitherto underutilized means of control over the absolute energy levels of QDs within electronic devices. Here, we show that the energy levels of lead sulfide QDs, measured by ultraviolet photoelectron spectroscopy, shift by up to 0.9 eV between different chemical ligand treatments. The directions of these energy shifts match the results of atomistic density functional theory simulations and scale with the ligand dipole moment. Trends in the performance of photovoltaic devices employing ligand-modified QD films are consistent with the measured energy level shifts. These results identify surface-chemistry-mediated energy level shifts as a means of predictably controlling the electronic properties of colloidal QD films and as a versatile adjustable parameter in the perfo...

TL;DR: In this article, the authors review the literature on corporate governance issues in Asia to develop region-specific and general lessons, and show that conventional and alternative corporate governance mechanisms can have limited effectiveness in systems with weak institutions and poor property rights.
Abstract: Corporate governance has received much attention in recent years, partly due to the Asian financial crisis. We review the literature on corporate governance issues in Asia to develop region-specific and general lessons. Much attention has been given to poor corporate sector performance, but most studies do not suggest Asian firms were badly run. The literature does confirm the limited protection of minority rights in Asia, allowing controlling shareholders to expropriate minority shareholders. Agency problems have been exacerbated by low corporate transparency associated with rent-seeking and relationship-based transactions, extensive group structures and diversification, and risky financial structures. The controlling shareholder bears some of agency costs in the form of share price discounts and expenditures on monitoring, bonding and reputation building. The Asian financial crisis further showed that conventional and alternative corporate governance mechanisms can have limited effectiveness in systems with weak institutions and poor property rights. Overall, the understanding of the determinants of firm organizational structures, corporate governance practices and outcomes remains limited, however.

08 Oct 2016TL;DR: The Connectionist Text Proposal Network (CTPN) as mentioned in this paper detects a text line in a sequence of fine-scale text proposals directly in convolutional feature maps, and develops a vertical anchor mechanism that jointly predicts location and text/non-text score of each fixed-width proposal.
Abstract: We propose a novel Connectionist Text Proposal Network (CTPN) that accurately localizes text lines in natural image. The CTPN detects a text line in a sequence of fine-scale text proposals directly in convolutional feature maps. We develop a vertical anchor mechanism that jointly predicts location and text/non-text score of each fixed-width proposal, considerably improving localization accuracy. The sequential proposals are naturally connected by a recurrent neural network, which is seamlessly incorporated into the convolutional network, resulting in an end-to-end trainable model. This allows the CTPN to explore rich context information of image, making it powerful to detect extremely ambiguous text. The CTPN works reliably on multi-scale and multi-language text without further post-processing, departing from previous bottom-up methods requiring multi-step post filtering. It achieves 0.88 and 0.61 F-measure on the ICDAR 2013 and 2015 benchmarks, surpassing recent results [8, 35] by a large margin. The CTPN is computationally efficient with 0.14 s/image, by using the very deep VGG16 model [27]. Online demo is available: http://textdet.com/.
