Active power control strategies for inverter-based distributed power generation adapted to grid-fault ride-through requirements

Distributed power generation is expected to deliver power into the grid without interruption during voltage dips. To improve system ride-through capabilities, a generalized active power control strategy is proposed for grid-interfacing inverters. Specifically, a current reference generation strategy based on symmetric-sequence components of unbalanced three-phase three-wire or four-wire systems is derived. It is shown that a single adjustable parameter can smoothly change the relative amplitudes of oscillating active and reactive power. This steering possibility enables grid-side inverters to optimally meet different requirements of coming standards. Simulations and experiments are carried out to validate the proposed strategy.
A Spatial-Constraint-Based Feature Point Matching Algorithm for the Positioning of Multiple IC Instances

With the development of integrated circuit (IC) chips, the semiconductor industry has begun using many ultrathin chips. To prevent cracking when they are picked up by the machinery, the precise pose of every chip must be provided using the image matching approach. Traditional feature point matching methods are robust to the pose changes of a single chip, but they are not effective for positioning multiple IC instances in one image. To solve this problem, a novel spatial-constraint-based feature point matching algorithm that uses both local information and the spatial topological relationship between feature points to divide the feature points among different IC instances is proposed. Various experiments using images captured of RFID chip pick-up equipment demonstrate that our algorithm results in correct positioning for multiple IC chips; is robust to translation, rotation, scaling, shearing and perspective transformation; and is not sensitive to occlusion and clutter. This algorithm may have many applications in the field of IC manufacturing and packaging.
The Use of Vector Seeds to Improve PSI-BLAST Sensitivity

The LSSD scan paths of each logic circuit chip on a circuit module are connected to additional test circuit chips on the same module. The test chips contain a random signal generator and data compression circuit to perform random stimuli signature generators and also contain switching circuits to connect the scan paths of the chips in parallel between different stages of the random signal generator and the data compression means for random stimuli signature generators and to disconnect the scan paths from the signal generator and data compression circuitry and arrange them serially in a single scan path to perform other tests.
Measuring the progress of projects using the time dependence of code changes

Tracking the progress of a project is often done through imprecise manually gathered information, like progress reports, or through automatic metrics such as Lines Of Code (LOC). Such metrics are too coarse-grained and too imprecise to capture all facets of a project. In this paper, we mine the code changes in the source code repository and study the concept of time dependence of code changes. Using this concept, we can track the progress of a software project as the progress of a building. We can examine how changes build on each other over time and determine the impact of these changes on the quality of a project. In particular, we study whether new changes are built just-in-time or if they build on older, stable code. Through a case study on two large open source projects (PostgreSQL and FreeBSD), we show that time dependence varies across projects and throughout the lifetime of each project. We also show that there is a high linear correlation between building on new code and the occurrence of bugs.
ViTS: Video Tagging System from Massive Web Multimedia Collections

The popularization of multimedia content on the Web has arised the need to automatically understand, index and retrieve it. In this paper we present ViTS, an automatic Video Tagging System which learns from videos, their web context and comments shared on social networks. ViTS analyses massive multimedia collections by Internet crawling, and maintains a knowledge base that updates in real time with no need of human supervision. As a result, each video is indexed with a rich set of labels and linked with other related contents. ViTS is an industrial product under exploitation with a vocabulary of over 2.5M concepts, capable of indexing more than 150k videos per month. We compare the quality and completeness of our tags with respect to the ones in the YouTube-8M dataset, and we show how ViTS enhances the semantic annotation of the videos with a larger number of labels (10.04 tags/video), with an accuracy of 80,87%. Extracted tags and video summaries are publicly available.1
Historical Prevalence of Infectious Diseases Within 230 Geopolitical Regions: A Tool for Investigating Origins of Culture

Regional differences in disease prevalence are associated with a wide array of cross-cultural differences. However, the complex relationships among culture, disease, and other ecological variables remain underinvestigated. Future research into the origins of cultural differences will benefit from the availability of a numerical index identifying the extent to which infectious diseases have been historically prevalent within regions defined by geopolitical borders. This article introduces such an index. This index is based on disease prevalence data obtained from old epidemiological atlases and is calculated for 230 geopolitical regions (mostly nations) around the world.

Coronary plaque quantification and fractional flow reserve by coronary computed tomography angiography identify ischaemia-causing lesions

Abstract Aims Coronary plaque characteristics are associated with ischaemia. Differences in plaque volumes and composition may explain the discordance between coronary stenosis severity and ischaemia. We evaluated the association between coronary stenosis severity, plaque characteristics, coronary computed tomography angiography (CTA)-derived fractional flow reserve (FFRCT), and lesion-specific ischaemia identified by FFR in a substudy of the NXT trial (Analysis of Coronary Blood Flow Using CT Angiography: Next Steps). Methods and results Coronary CTA stenosis, plaque volumes, FFRCT, and FFR were assessed in 484 vessels from 254 patients. Stenosis >50% was considered obstructive. Plaque volumes (non-calcified plaque [NCP], low-density NCP [LD-NCP], and calcified plaque [CP]) were quantified using semi-automated software. Optimal thresholds of quantitative plaque variables were defined by area under the receiver-operating characteristics curve (AUC) analysis. Ischaemia was defined by FFR or FFRCT ≤0.80. Plaque volumes were inversely related to FFR irrespective of stenosis severity. Relative risk (95% confidence interval) for prediction of ischaemia for stenosis >50%, NCP ≥185 mm3, LD-NCP ≥30 mm3, CP ≥9 mm3, and FFRCT ≤0.80 were 5.0 (3.0–8.3), 3.7 (2.4–5.6), 4.6 (2.9–7.4), 1.4 (1.0–2.0), and 13.6 (8.4–21.9), respectively. Low-density NCP predicted ischaemia independent of other plaque characteristics. Low-density NCP and FFRCT yielded diagnostic improvement over stenosis assessment with AUCs increasing from 0.71 by stenosis >50% to 0.79 and 0.90 when adding LD-NCP ≥30 mm3 and LD-NCP ≥30 mm3 + FFRCT ≤0.80, respectively. Conclusion Stenosis severity, plaque characteristics, and FFRCT predict lesion-specific ischaemia. Plaque assessment and FFRCT provide improved discrimination of ischaemia compared with stenosis assessment alone.
Microglia Transcriptome Changes in a Model of Depressive Behavior after Immune Challenge

Depression symptoms following immune response to a challenge have been reported after the recovery from sickness. A RNA-Seq study of the dysregulation of the microglia transcriptome in a model of inflammation-associated depressive behavior was undertaken. The transcriptome of microglia from mice at day 7 after Bacille Calmette Guérin (BCG) challenge was compared to that from unchallenged Control mice and to the transcriptome from peripheral macrophages from the same mice. Among the 562 and 3,851 genes differentially expressed between BCG-challenged and Control mice in microglia and macrophages respectively, 353 genes overlapped between these cells types. Among the most differentially expressed genes in the microglia, serum amyloid A3 (Saa3) and cell adhesion molecule 3 (Cadm3) were over-expressed and coiled-coil domain containing 162 (Ccdc162) and titin-cap (Tcap) were under-expressed in BCG-challenged relative to Control. Many of the differentially expressed genes between BCG-challenged and Control mice were associated with neurological disorders encompassing depression symptoms. Across cell types, S100 calcium binding protein A9 (S100A9), interleukin 1 beta (Il1b) and kynurenine 3-monooxygenase (Kmo) were differentially expressed between challenged and control mice. Immune response, chemotaxis, and chemokine activity were among the functional categories enriched by the differentially expressed genes. Functional categories enriched among the 9,117 genes differentially expressed between cell types included leukocyte regulation and activation, chemokine and cytokine activities, MAP kinase activity, and apoptosis. More than 200 genes exhibited alternative splicing events between cell types including WNK lysine deficient protein kinase 1 (Wnk1) and microtubule-actin crosslinking factor 1(Macf1). Network visualization revealed the capability of microglia to exhibit transcriptome dysregulation in response to immune challenge still after resolution of sickness symptoms, albeit lower than that observed in macrophages. The persistent transcriptome dysregulation in the microglia shared patterns with neurological disorders indicating that the associated persistent depressive symptoms share a common transcriptome basis.
Cross-correlation technique for revealing defects in differential pulsed eddy current defectoscopy

The utilization of the cross-correlation technique in pulsed eddy current testing is described and illustrated with an example of an artificial defect in an electrically conductive steel plate. The investigated eddy current probe is of a differential type, consisting of one excitation and two sensing coils with a ferrite magnetic circuit. The numerical solution is carried out in the COMSOL Multiphysics using Magnetic field and Electrical circuit modules. The results are verified by performing laboratory experiment. Important aspects of the cross-correlation in the pulsed eddy current testing are then analyzed and discussed.
Web-Based Verification on the Representativeness of Terms Extracted from Single Short Documents

Single document summarization is useful for extracting the major ideas from huge amount of daily information. However, it's a challenge to distinguish the relative importance among terms. In this paper, we propose a Web-based approach to term verification. Search-results of extracted terms are utilized as their expanded representation, and their similarity with the original document are calculated as an estimate of term representative ness. We experimented with term extraction methods on multilingual news extracts and compared the effectiveness of term verification with various Jaccard similarity measures. The experimental results show the feasibility of Web-based verification on the representativeness of extracted terms.
HER-2 testing and trastuzumab therapy for metastatic breast cancer: a cost-effectiveness analysis.

PURPOSE Trastuzumab therapy has been shown to benefit metastatic breast cancer patients whose tumors exhibit HER-2 protein overexpression or gene amplification. Several tests of varying accuracy and cost are available to identify candidates for trastuzumab. We estimated the cost-effectiveness of alternative HER-2 testing and trastuzumab treatment strategies. PATIENTS AND METHODS We performed a decision analysis using a state-transition model to simulate clinical practice in a hypothetical cohort of 65-year-old metastatic breast cancer patients. Outcomes were quality-adjusted life-years (QALYs), lifetime cost, and incremental cost-effectiveness ratio (ICER). Interventions included testing with the HercepTest (DAKO, Carpinteria, CA) immunohistochemical assay alone, fluorescence in situ hybridization (FISH) alone, and both tests, followed by trastuzumab and chemotherapy for patients with positive test results and chemotherapy alone for patients with negative test results. RESULTS In the base case, initial HercepTest with FISH confirmation of all positive results had an ICER of $125,000 per QALY gained. The incremental cost-effectiveness of initial FISH was $145,000 per QALY gained. Other strategies yielded the same or poorer effectiveness at a higher cost, or lower effectiveness at a lower cost, but with a less favorable ICER. These findings persisted under a range of assumptions, and only changes in test characteristics substantially altered results. CONCLUSION It is more cost-effective to use FISH alone or as confirmation of all positive HercepTest results, rather than using FISH to confirm only weakly positive results or using HercepTest alone. When multiple tests are available to identify treatment candidates, test characteristics may have a substantial impact on the aggregate costs and effectiveness of treatment.
IMMIGRATION STRESS AND RELATIONSHIP SATISFACTION IN LATINO COUPLES: THE ROLE OF DYADIC COPING

This study examined (a) the relationship of Latino partners' overall immigration stress and each of its different dimensions with their relationship satisfaction and (b) whether a partner's support (supportive dyadic coping) and the couple's conjoint efforts to cope with stress (common dyadic coping) can moderate those relationships. An Actor-Partner Interdependence Model (APIM; Kenny, 1996) was used to analyze self-report data collected from 104 Latino immigrant couples in the U.S. Structural equation modeling results suggest that common dyadic coping and the supportive dyadic coping provided by the male partner can attenuate the negative association of various aspects of Latinas' immigration stress mostly with her relationship satisfaction and to some extent with her male partner's as well. By contrast, common dyadic coping and the female partner's supportive dyadic coping do not play any moderating role in the relationship between most dimensions of the male immigration stress and either partner's rela.
Ethnicity and Sentencing Outcomes in U.S. Federal Courts: Who is Punished More Harshly?

Using federal court data collected by the U.S. Sentencing Commission for the years 1993–1996, this study examines racial/ethnic differences-white versus black versus white-Hispanic versus black-Hispanic—in sentencing outcomes and criteria under the federal sentencing guidelines. Regression analyses of incarceration and term-length decisions reveal considerable judicial consistency in the use of sentencing criteria for all defendants; however, important racial/ethnic disparities in sentencing emerge. Consistent with theoretical hypotheses, the authors find that ethnicity has a small to moderate effect on sentencing outcomes that favors white defendants and penalizes Hispanic defendants; black defendants are in an intermediate position. Hispanic drug offenders are most at risk of receiving the harshest penalties, and their harsher treatment is most pronounced in prosecutor-controlled guidelines departure cases. These findings highlight both a classic organizational tension noted by Weber and a fundamental dilemma in policy efforts to structure sentencing processes (formal rationality) while allowing for judicial and prosecutorial discretion (substantive rationality). The findings also broaden our view of the continuing significance of race in American society—as a matter confronting not only blacks but also Hispanics and perhaps other ethnic groups as well.
Synaptic and functional linkages between spinal premotor interneurons and hand-muscle activity during precision grip

Grasping is a highly complex movement that requires the coordination of a number of hand joints and muscles. Previous studies showed that spinal premotor interneurons (PreM-INs) in the primate cervical spinal cord have divergent synaptic effects on hand motoneurons and that they might contribute to hand-muscle synergies. However, the extent to which these PreM-IN synaptic connections functionally contribute to modulating hand-muscle activity is not clear. In this paper, we explored the contribution of spinal PreM-INs to hand-muscle activation by quantifying the synaptic linkage (SL) and functional linkage (FL) of the PreM-INs with hand-muscle activities. The activity of 23 PreM-INs was recorded from the cervical spinal cord (C6–T1), with EMG signals measured simultaneously from hand and arm muscles in two macaque monkeys performing a precision grip task. Spike-triggered averages (STAs) of rectified EMGs were compiled for 456 neuron–muscle pairs; 63 pairs showed significant post-spike effects (PSEs; i.e., SL). Conversely, 231 of 456 pairs showed significant cross-correlations between the IN firing rate and rectified EMG (i.e., FL). Importantly, a greater proportion of the neuron–muscle pairs with SL showed FL (43/63 pairs, 68%) compared with the pairs without SL (203/393, 52%), and the presence of SL was significantly associated with that of FL. However, a significant number of pairs had SL without FL (SL∩! FL, n = 20) or FL without SL (! SL∩FL, n = 203), and the proportions of these incongruities exceeded the number expected by chance. These results suggested that spinal PreM-INs function to significantly modulate hand-muscle activity during precision grip, but the contribution of other neural structures is also needed to recruit an adequate combination of hand-muscle motoneurons.
Image completion with generation of rotated patterns and efficient matching

Image completion is a method for completing missing parts caused by the removal of foreground or background elements from an image in a plausible way. In the conventional method, the missing parts of an image are completed by optimizing the objective function, which is defined based on pattern similarity between the missing region and the rest of the image (data region). However, the resultant image could be deteriorated according to variations of patterns in the data region. Although augmenting the pattern variations in the data region leads to good completion result, the processing time to search the plausible pattern in the augmented data increases explosively. In this paper, we propose an extended method considering rotated pattern variations of data region as well as suppressing the computational time by utilizing local orientations of rotated patterns. The effectiveness of the proposed method is validated by comparing with the conventional method.
Porcine Epidemic Diarrhea Virus Nucleocapsid Protein Antagonizes Beta Interferon Production by Sequestering the Interaction between IRF3 and TBK1

ABSTRACT Porcine epidemic diarrhea virus (PEDV), a porcine enteropathogenic coronavirus, causes lethal watery diarrhea in piglets and results in large economic losses in many Asian and European countries. A large-scale outbreak of porcine epidemic diarrhea occurred in China in 2010, and the virus emerged in the United States in 2013 and spread rapidly, posing significant economic and public health concerns. Previous studies have shown that PEDV infection inhibits the synthesis of type I interferon (IFN), and viral papain-like protease 2 has been identified as an IFN antagonist. In this study, we found that the PEDV-encoded nucleocapsid (N) protein also inhibits Sendai virus-induced IFN-β production, IFN-stimulated gene expression, and activation of the transcription factors IFN regulatory factor 3 (IRF3) and NF-κB. We also found that N protein significantly impedes the activation of the IFN-β promoter stimulated by TBK1 or its upstream molecules (RIG-I, MDA5, IPS-1, and TRAF3) but does not counteract its activation by IRF3. A detailed analysis revealed that the PEDV N protein targets TBK1 by direct interaction and that this binding sequesters the association between TBK1 and IRF3, which in turn inhibits both IRF3 activation and type I IFN production. Together, our findings demonstrate a new mechanism evolved by PEDV to circumvent the host's antiviral immunity. IMPORTANCE PEDV has received increasing attention since the emergence of a PEDV variant in China and the United States. Here, we identify nucleocapsid (N) protein as a novel PEDV-encoded interferon (IFN) antagonist and demonstrate that N protein antagonizes IFN production by sequestering the interaction between IRF3 and TBK1, a critical step in type I IFN signaling. This adds another layer of complexity to the immune evasion strategies evolved by this economically important viral pathogen. An understanding of its immune evasion mechanism may direct us to novel therapeutic targets and more effective vaccines against PEDV infection.
An Approach to Cloth Synthesis and Visualization

An analysis of one of the approaches to cloth modeling is carried out in this paper. The real 3D structure of the cloth at micro level is considered and the lighting simulation with the accuracy control is provided. The simulation result in BSDF form is a full description of optical properties of the cloth sample. It allows us to produce the “far view” of the cloth accurately and fast.
Improving image classification by orthogonality of sparse codes

Sparse Coding (SC) is an approach widely used in image classification. It allows to reconstruct the signal with few elements and follows the specific scheme of Bag-of-Words (BoW). However, we can observe a decorrelation between input patches and reconstructed patches. To answer that, Graph regularized Sparse Coding (GSC) exists. As GSC works on the training set, we propose a new modeling, Joint Sparse Coding (JSC), for the testing set. JSC can be seen as a tradeoff between SC and GSC. To go furthermore, we explore the simple fusion of models. To explain the observations of the fusion results, we will be led to study the orthogonality properties by the cosine computation. These applied on UIUCsports, 17Flowers and scenes15 lead us to put forward the various qualities of the studied bases and sparse representation. We demonstrate a significant improvement of the State-of-the-Art for the UIUCsports database.
Match-Making to Enhance the Mentoring Relationship in Student Teaching: Learning from a Simple Personality Instrument

Four student teachers in secondary science education were matched with cooperating teachers based on four personality constructs identified from a simple Myers-Brigg type inventory. Placement decisions were based on compatibility of primary or secondary temperaments informing pedagogical approach in the classroom and particular skills needed for mentorship. Teaching dyads were most fruitful where primary or secondary temperaments were in common, but not both. Some level of dissonance in temperaments fostered pedagogical growth in one student teacher. All temperaments studied supported learning to teach science with unique strengths. One construct called “relational” appeared necessary in mentor teachers for fostering relationships with ample support and communication.
