Coordination strategy for harmonic compensation using multiple distributed resources

Nowadays, due to the development of power electronic technology, nonlinear electronic loads using power electronic circuits are widespread in power grids. The loads can consume more reliable and high-quality power through the power conversion circuits. However, the power grids can suffer significant harmonic currents caused by these power electronic circuits. This paper proposes a new harmonic compensation method of utilizing multiple power inverters that integrate distributed resources (DRs) to a microgrid. Therefore, harmonic problems can be solved without installing additional power filters to the grids. To coordinate multiple various DGs such as small distributed generators (DGs) and battery energy storage systems (BESSs), the proposed method considers multiple objectives in terms of energy cost, generation margins of DGs and energy margins of BESSs. The optimization algorithm is constructed based on fuzzy multi-objective optimization model so that the proposed method assigns the additional output power of each DR that is needed for harmonic elimination. Simulations of the suggested coordination strategy for harmonic compensation using multiple DRs are conducted in the microgrid including two inverter-based DGs and one BESS to verify the performance of the proposed method.
Large Scale Localization - For Mobile Outdoor Augmented Reality Applications

In this paper, we present an original localization system for large scale outdoor environments which uses a markerless vision-based approach to estimate the camera pose. It relies on natural feature points extracted from images. Since this type of method is sensitive to brightness changes, occlusions and sudden motions which are likely to occur in outdoor environment, we use two more sensors to assist the vision process. In our work, we would like to demonstrate the feasibility of an assistance scheme in large scale outdoor environment. The intent is to provide a fallback system for the vision in case of failure as well as to reinitialize the vision system when needed. The complete localization system aims to be autonomous and adaptable to different situations. We present here an overview of our system, its performance and some results obtained from experiments performed in an outdoor environment under real conditions.
Complementary Resistive Switch-Based Arithmetic Logic Implementations Using Material Implication

Memristors are considered among the most promising future building blocks of next-generation digital systems. This paper focuses on specific ways to implement logic and arithmetic unit using memristors. In particular, we present a set of complementary resistive switching (CRS)-based stateful logic operations that use material implication to provide the basic logic functionalities needed to realize logic circuits. The proposed solution benefits from the exponential reduction in sneak path current in crossbar implemented logic. This paper also presents a closed-form expression for sneak current and analyzes the impact of device variation on the behavior of the proposed logic blocks. Our technique, as other similar techniques proposed in the literature, requires several sequential steps to perform the computation. However, in this paper, we show that only three steps are required for implementing N input nand gate, whereas previously proposed memristor-based stateful logic needs N + 1 steps. We validated the effectiveness of our solution through cadence spectre circuit simulator on a number of logic circuits. Finally, we extended this approach for arithmetic circuits with an 8-bit adder and a 4-bit multiplier.
Pre-edge structure analysis of Ti K-edge polarized X-ray absorption spectra in TiO2 by full-potential XANES calculations.

The pre-edge region of Ti N-edge polarized XANES spectra in TiO2-mtile is investigated by full-potential calculations based on the finite-difference method. Both dipolar and quadrupolar transitions are considered. The use of"non muffin-tin" potential allows a clear interpretation of the pre-edge features. The results are consistent with Full-potential LAPW band structure calculations, and are also compared with multiple-scattering calculations.
Invasion of HEp-2 cells by fecal isolates of Aeromonas hydrophila

Human diarrheal isolates of Aeromonas hydrophila were found to be invasive in HEp-2 cell monolayers. Microscopic examination of two isolates from patients with symptoms of dysentery revealed that infected HEp-2 cells contained up to 50 bacteria localized within areas of the cytoplasm. A quantitative invasion assay was developed, using viable counts of total intracellular bacteria. Five fecal isolates of A. hydrophila were classified as invasive, with an average of 0.1 up to 2 bacteria per HEp-2 cell, as compared to 7 for an invasive Escherichia coli strain. 3 other fecal isolates, 1 reference strain, and 10 water isolates of A. hydrophila were similar to a noninvasive E. coli strain, with less than 0.008 bacteria per HEp-2 cell. All isolates were screened for plasmid DNA; no common plasmid was found in the invasive strains, and the loss of a 6.0-megadalton plasmid from one of these strains had no observable effect on invasiveness. Thus some A. hydrophila isolates are capable of cellular penetration and replication, and this may be an important chromosomally determined virulence property of the organism.
On the Reliability of Implicit and Explicit Memory Measures

Functional dissociations between implicit and explicit memory tests often take the form of large differences between groups or experimental conditions (e.g., amnesics and controls, elderly and younger persons, or persons learning with and without a distracting secondary task) when performance is assessed using explicit memory tests, whereas no difference is observed with implicit memory tests. We argue that the interpretation of such dissociations in terms of the memory processes or systems involved in performance is problematic because the same data pattern would emerge as a result of a mere methodological artifact, that is, the situation that implicit memory tests have low reliability whereas explicit memory tests are fairly reliable measurement instruments. We present reasons for such a reliability difference, and we demonstrate it empirically in Experiments 1a, 1b, and 2. However, our analysis also shows, and Experiment 3 confirms empirically, that implicit memory tests need not necessarily be less reliable measurement instruments than explicit memory tests.
Definition of major bleeding in clinical investigations of antihemostatic medicinal products in non‐surgical patients

Summary. A variety of definitions of major bleeding have been used in published clinical studies, and this diversity adds to the difficulty in comparing data between trials and in performing meta‐analyses. In the first step towards unified definitions of bleeding complications, the definition of major bleeding in non‐surgical patients was discussed at the Control of Anticoagulation Subcommittee of the International Society on Thrombosis and Haemostasis. Arising from that discussion, a definition was developed that should be applicable to studies with all agents that interfere with hemostasis, including anticoagulants, platelet function inhibitors and fibrinolytic drugs. The definition and the text that follows have been reviewed and approved by the cochairs of the subcommittee and the revised version is published here. The intention is to also seek approval of this definition from the regulatory authorities.
Mutual Fund Flows and Investor Sentiment

I show that the shape of flow–performance relationship among open-end funds varies with investor sentiment. This link is stronger when the market tone is optimistic. Cross-sectional comparison reveals that the convexity of the relationship is more pronounced among funds of the type that receives less demand; especially among risky funds in low-investor-sentiment quarters. Managers of such funds that are under-performing have incentives to increase the risk of their portfolios; they do this by betting more on the market index and buying larger stocks in low-sentiment quarters. Applying Baker and Wurgler’s (2006) findings suggests that this strategy is sub-optimal.
Revisiting 3D information landscapes for the display of art historical web content

As of today, a lot of different approaches have been dealing with the presentation of art history resources on the Web. While the majority of these focused on traditional 2D methods of display, some did introduce the application of 3D visualization metaphors. Such environments were, however, usually tailored to a specific collection or topic, such as a featured artist or epoch. Meanwhile, the increasing availability of valuable metadata resources has opened up the perspective for the automatic creation of such 3D environments by integrating semantic data sources through the Web. In this work we therefore present a prototype that automatically constructs a 3D environment from semantic art history related Web resources, offering users the opportunity to explore art history following the visualized structure of relations between historical actors of the field. Traversing this historical social network enables users to encounter previously unknown artists and their work in a serendipitous way.
Siglec‐H is a microglia‐specific marker that discriminates microglia from CNS‐associated macrophages and CNS‐infiltrating monocytes

Several types of myeloid cell are resident in the CNS. In the steady state, microglia are present in the CNS parenchyma, whereas macrophages reside in boundary regions of the CNS, such as perivascular spaces, the meninges and choroid plexus. In addition, monocytes infiltrate into the CNS parenchyma from circulation upon blood–brain barrier breakdown after CNS injury and inflammation. Although several markers, such as CD11b and ionized calcium‐binding adapter molecule 1 (Iba1), are frequently used as microglial markers, they are also expressed by other types of myeloid cell and microglia‐specific markers were not defined until recently. Previous transcriptome analyses of isolated microglia identified a transmembrane lectin, sialic acid‐binding immunoglobulin‐like lectin H (Siglec‐H), as a molecular signature for microglia; however, this was not confirmed by histological studies in the nervous system and the reliability of Siglec‐H as a microglial marker remained unclear. Here, we demonstrate that Siglec‐H is an authentic marker for microglia in mice by immunohistochemistry using a Siglec‐H‐specific antibody. Siglec‐H was expressed by parenchymal microglia from developmental stages to adulthood, and the expression was maintained in activated microglia under injury or inflammatory condition. However, Siglec‐H expression was absent from CNS‐associated macrophages and CNS‐infiltrating monocytes, except for a minor subset of cells. We also show that the Siglech gene locus is a feasible site for specific targeting of microglia in the nervous system. In conclusion, Siglec‐H is a reliable marker for microglia that will allow histological identification of microglia and microglia‐specific gene manipulation in the nervous system.
Benefit of NMOS by Compressive SiN as Stress Memorization Technique and Its Mechanism

In this letter, we certify that the compressive SiN capping layer has more potential than the tensile layer for fabrication using the stress memorization technique to enhance NMOS mobility. The mechanism that we have proposed implies that the conventional choice of the capping layer should be modulated from the point of view of stress shift rather than using the highest tensile film.
Influence of Husbands on the Outcome of their Agoraphobic Wives' Therapy

Of 30 agoraphobic married women undertaking home-based behaviour therapy, 15 each had a female friend as co-therapist and 15 had their own husband as co-therapist. At 12 months follow-up, women spent a mean of approximately 40 minutes a day more outside the home alone than at baseline. Women assisted by female friends made somewhat more behavioural gains than those assisted by husbands. Women in both groups whose husbands had been more depressed 2 months after the beginning of therapy did less well at 6 months. Husbands who become more depressed may retard their wives' progress in therapy, but the effect was small, and was outweighed by other considerations.
Stereoscopic image generation of background terrain scenes

The reconstruction of 3D terrain geometry from images is essential for compositing CG objects into a live‐action background or for 2D to 3D conversion of terrain scenes. We present a novel mesh refinement algorithm for the creation of stereoscopic images of terrain scenes. Previous approaches emphasise the smoothness of the resulting terrain mesh over accuracy 1 . Point cloud‐based methods cannot effectively recover the entire surface, leading to visual discrepancies after monocular sequences are converted into 3D stereo. As misalignment or inaccurate 3D terrain data over corresponding 2D background images can result in visual fatigue when stereo sequences are generated, ensuring accuracy of the reconstructed geometry is very important. To achieve the necessary accuracy, our method evaluates mesh errors utilising a texture projection onto the geometry and refines the mesh using Laplacian‐based editing. Our algorithm automatically generates stereoscopic images of terrain scenes. In addition, our method simplifies identification and compositing of foreground objects on the terrain geometry.

Implementation of enterprise resource planning (ERP) systems: Issues and challenges

Enterprise resource planning (ERP) systems are a growing area of research in business information systems. The primary purpose of this research is to review the literature on ERP implementation and to present results of a case study on ERP implementation. An exploratory case study was conducted to study these research issues. The case study consisted of a survey and interview of 25 employees at one organization. The results provide data analysis findings from the survey and qualitative findings from the interview. Using this case study, the chapter indicates the presence of four phases in ERP implementation through the support from qualitative interviews. Using t-tests, the results confirm the presence of a positive feeling of users toward the four ERP implementation phases.

Capacity of active power reserve for frequency control enhanced by distributed generators

Usually, ancillary services are provided by large conventional generators; however, with the growing interest in distributed generation to satisfy energy and environmental requirements, it seems reasonable to assume that these services could also be provided by distributed generators in an economical and efficient way. In this paper, a proposal for enhancement of the capacity of active power reserve for frequency control using distributed generators is presented. The goal is to minimize the payments done by the transmission system operator to conventional and distributed generators for this ancillary service and for the energy needed to satisfy loads and system losses, subject to a set of constraints. In order to perform analysis, the proposal was implemented using data of the IEEE 30-bus transmission test system. Comparisons were performed considering conventional generators without and with distributed generators installed in the system.
Core Principles for Effective Banking Supervision: New Concepts and Challenges

This paper examines certain fundamental issues raised by the existence and application of the newly revised Core Principles for Effective Banking Supervision. First, what expectations are imposed upon jurisdictions that adopt the Core Principles? Second, are the Core Principles an effective response to the international financial crisis? Third, what is the legal status of the Core Principles–mere guidelines, a significant new source of law in international practice, or something in between? The paper argues that the Core Principles represents a distinctive and highly effective approach to the coordination of legal norms across borders that, in the context of international banking practice, may operate as a set of functionally binding norms – and possibly a new source of law in international practice.
Analysis of exchange rate movements: a case study of Singapore

This study provides a holistic perspective of Singapore’s exchange rate determination by integrating theory, econometrics and institutional realities. We show how external conditions, economic fundamentals and MAS intervention have affected the Singapore dollar. Because the Singapore dollar is strongly managed, it is difficult to forecast exchange rate trends using an ARIMA model. Therefore, one has to turn to more judgmental methods to ‘predict’ exchange rate trends.

Power quality investigation of a typical Telecom data centre electrical network

In this paper a power quality investigation of the Libyan Telecom Technology (LTT) headquarter and data center electrical distribution network is presented. A full description of the center single-phase and three-phase load types are illustrated. Loads individual current harmonic distortion theoretical levels are explained. Accumulated current harmonic components at each connection point are also predicted. Estimation process involves an optimistic and pessimistic approach of the excepted harmonics due to the mix of the various data center loads at each busbar. A real measurement results of the current and voltage Total Harmonic Distortion (THD) and line power factor are presented, compared and assessed according to the IEEE519-1992 harmonic control recommendations. The paper proposes some practical procedures and precautions to be applied in order to improve the overall power quality of the data center that could minimize the related risk and distortion issues.
Antitumor Potential of Lactaptin

A number of naturally occurring proteins that selectively induce apoptosis of cancer cells were recently used to develop novel anticancer drug substances. Human milk is a source of multiple bioactive peptides, some of which are activated by proteolysis. Lactaptin is an 8.6 kDa proteolytic fragment of kappa-casein isolated from human milk. This mini review describes apoptotic properties, mechanism of action and antitumor activity of lactaptin.
Title TET 2 mutations affect non-CpG island DNA methylation at enhancers and transcription factor binding sites in chronic myelomonocytic leukemia

TET2 enzymatically converts 5-methylcytosine to 5-hydroxymethylcytosine as well as other covalently-modified cytosines and its mutations are common in myeloid leukemia. However, the exact mechanism and the extent to which TET2 mutations affect DNA methylation remain in question. Here we report on DNA methylomes in TET2 wild type (TET2-WT) and mutant (TET2-MT) cases of chronic myelomonocytic leukemia (CMML). We analyzed 85,134 CpG sites (28,114 sites in CpG islands (CGIs) and 57,020 in non-CpG islands (NCGIs)). TET2 mutations do not explain genome-wide differences in DNA methylation in CMML, and we found few and inconsistent differences at CGIs between TET2-WT and TET2-MT cases. By contrast, we identified 409 (0.71%) TET2-specific differentially methylated CpGs (tet2-DMCs) in NCGIs, 86% of which were hypermethylated in TET2-MT cases, suggesting a strikingly different biology of the effects of TET2 mutations at CGIs and NCGIs. DNA methylation of tet2-DMCs at promoters and non-promoters repressed gene expression. Tet2-DMCs showed significant enrichment at hematopoietic-specific enhancers marked by H3K4me1, and at binding sites for the transcription factor p300. Tet2-DMCs showed significantly lower 5-hydroxymethylcytosine in TET2-MT cases. We conclude that leukemia-associated TET2 mutations affect DNA methylation at NCGI regions containing hematopoietic-specific enhancers and transcription factor binding sites. on July 21, 2017. © 2015 American Association for Cancer Research. cancerres.aacrjournals. org Downloaded from Author manuscripts have been peer reviewed and accepted for publication but have not yet been edited.

Density‐enhanced perceptual mosaic on GPU

Image mosaic effects are wildly applied in print media, domestic decoration, and many image beautification applications. However, the current image mosaic methods are mostly based on fixed‐size image tiles, simple color adjustment, and irregular image segmentation, which are inaccurate and very time‐consuming. In this paper, we present a graphics processing unit‐accelerated perceptual mosaic using density tiles replacement and brightness lighting optimization, keeping original image structure details and providing more expressive visual effects. Automatic density replacement map segmentation and color‐based region tiles replacement are performed to facilitate the mosaic. Delicate brightness optimization and perceptual color correction are further applied to enhance expressive lighting effects. We also consider the salience perception of images and similarity correlation among neighboring tiles for our perceptual mosaic. The experimental results have shown the efficiency and high‐quality performance of our density‐enhanced perceptual mosaic on graphics processing unit. Copyright © 2016 John Wiley & Sons, Ltd.
Overproduction, purification, and ATPase activity of the Escherichia coli RuvB protein involved in DNA repair

The ruvA and ruvB genes of Escherichia coli constitute an operon which belongs to the SOS regulon. Genetic evidence suggests that the products of the ruv operon are involved in DNA repair and recombination. To begin biochemical characterization of these proteins, we developed a plasmid system that overproduced RuvB protein to 20% of total cell protein. Starting from the overproducing system, we purified RuvB protein. The purified RuvB protein behaved like a monomer in gel filtration chromatography and had an apparent relative molecular mass of 38 kilodaltons in sodium dodecyl sulfate-polyacrylamide gel electrophoresis, which agrees with the value predicted from the DNA sequence. The amino acid sequence of the amino-terminal region of the purified protein was analyzed, and the sequence agreed with the one deduced from the DNA sequence. Since the deduced sequence of RuvB protein contained the consensus sequence for ATP-binding proteins, we examined the ATP-binding and ATPase activities of the purified RuvB protein. RuvB protein had a stronger affinity to ADP than to ATP and weak ATPase activity. The results suggest that the weak ATPase activity of RuvB protein is at least partly due to end product inhibition by ADP.
