Improved watermark detection robust to camcorder capture based on quadrangle estimation

In this paper, we propose a blind watermark detection scheme which is robust against composite geometric distortions. The composite geometric distortions mean that an image or a video is rotated, perspective-projected, and resized at the same time. It commonly happens during capturing a movie in a theater by a camcorder illegally. Local auto-correlation function (LACF) with a novel estimation model is utilized for calculating composite geometric distortions. We demonstrate robustness of the presented scheme against composite geometric distortions for digital cinema.
Integer points on a family of elliptic curves

Set of m positive integers is called a Diophantine m-tuple if the product of its any two distinct elements increased by 1 is a perfect square. First example of a Diophantine quadruple is found by Fermat, and it was {1, 3, 8, 120} (see [6, p. 517]). In 1969, Baker and Davenport [2] proved that if d is a positive integer such that {1, 3, 8, d} is a Diophantine quadruple, then d has to be 120. Recently, in [9], we generalized this result to all Diophantine triples of the form {1, 3, c}. The fact that {1, 3, c} is a Diophantine triple implies that c = ck for some positive integer k, where the sequence (ck) is given by c0 = 0, c1 = 8, ck+2 = 14ck+1 − ck + 8, k ≥ 0. Let ck + 1 = sk, 3ck + 1 = t 2 k. It is easy to check that ck±1ck + 1 = (2ck ± sktk). The main result of [9] is the following theorem.
Bmc Musculoskeletal Disorders Characteristics and Natural Course of Vertebral Endplate Signal (modic) Changes in the Danish General Population

Background: Vertebral endplate signal changes (VESC) are more common among patients with low back pain (LBP) and/or sciatica than in people who are not seeking care for back pain. The distribution and characteristics of VESC have been described in people from clinical and non-clinical populations. However, while the clinical course of VESC has been studied in patients, the natural course in the general population has not been reported. The objectives of this prospective observational study were to describe: 1) the distribution and characteristics of VESC in the lumbar spine, 2) its association with disc degeneration, and 3) its natural course from 40 to 44 years of age.
Open issues in organizing computer systems conferences

The Workshop on Organizing Workshops, Conferences, and Symposia for Computer Systems (WOWCS) was organized to "bring together conference organizers (past, present, and future) and other interested people to discuss the issues they confront. " In conjunction with WOWCS, we survey some previous publications that discuss open issues related to organizing computer systems conferences, especially concerning conduct and management of the review process. We also list some topics about which we wish WOWCS had received submissions, but did not; these could be good topics for future articles.
Interdecadal Variations in ENSO Influences on Northwest Pacific–East Asian Early Summertime Climate Simulated in CMIP5 Models

The present study investigates interdecadal modulations of the El Nino-Southern Oscillation (ENSO) influence on the climate of the northwest Pacific (NWP) and East Asia (EA) in early boreal summer following a winter ENSO event, based on 19 simulations from phase 5 of the Coupled Model Intercomparison Project (CMIP5). In the historical run, 8 out of 19 models capture a realistic relationship between ENSO and NWP early summer climate-an anomalous anticyclone develops over the NWP following a winter El Nino event- and the interdecadal modulations of this correlation. During periods when the association between ENSO and NWP early summer climate is strong, ENSO variance and ENSO-induced anomalies of summer sea surface temperature (SST) and tropospheric temperature over the tropical Indian Ocean (TIO) all strengthen relative to periods when the association is weak. In future projections with representative concentration pathways 4.5 and 8.5, the response of TIO SST, tropospheric temperature, and NWP anomalous anticyclone to ENSO all strengthen regardless of ENSO amplitude change. In a warmer climate, low-level specific humidity response to interannual SST variability strengthens following the Clausius-Clapeyron equation. The resultant intensification of tropospheric temperature response to interannual TIO warming is suggested as the mechanism for the strengthened ENSO effect on NWP-EA summer climate.
Handbook of Experimental Economics

This book, which comprises eight chapters, presents a comprehensive critical survey of the results and methods of laboratory experiments in economics. The first chapter provides an introduction to experimental economics as a whole, with the remaining chapters providing surveys by leading practitioners in areas of economics that have seen a concentration of experiments: public goods, coordination problems, bargaining, industrial organization, asset markets, auctions, and individual decision making.
A Functional Polymorphism in the Promoter Region of MicroRNA-146a Is Associated with the Risk of Alzheimer Disease and the Rate of Cognitive Decline in Patients

miR146a is well known for its regulatory role in the immune response and inflammation. Recent studies have demonstrated the links between miR146a and Alzheimer disease (AD) and suggested that miR146a may be involved in neuroinflammation and the metabolism of amyloid-β (Aβ), which are critical events in AD pathology. Although genetic studies have focused on the association between the miR146a gene and susceptibility to several diseases, no association study of miR146a variability with AD has been conducted. In this report, we performed a case-control association study to analyze the genotype and allele distributions of the miR146a, rs2910464 and rs57095329 polymorphisms in a Chinese population consisting of 292 AD cases and 300 healthy controls. We found a significant difference in the genotypes and allele frequencies of rs57095329 between the AD cases and the controls (p = 0.0147 and p = 0.0184, respectively), where the AA genotype of rs57095329 was associated with an increased risk of AD as well the cognitive decline in AD patients. Additionally, the AA genotype of rs57095329 exhibited significantly higher miR146a expression than the GG+GA genotypes of rs2910164 in the peripheral blood cells (PBMCs) of healthy individuals and had a stronger effect on the production of IL-6 and IL-1β when the cells were stimulated with LPS. Our data provide preliminary evidence that the rs57095329 polymorphism in the miR146a promoter is involved in the genetic susceptibility to AD, and this risk AA genotype may increase the expression of miR146a and influence certain proinflammatory cytokines, thus playing a role in the pathogenesis of AD.
The “point” of positive organizational behavior

Perhaps the most important “Point” we would like to make in this “Point-Counterpoint” on positive organizational behavior is the role that research must play in this evolving area of study. We follow this point on the importance of research by drawing from recent findings that indicate in discussions such as this point and counterpoint, that taking a positive approach leads to more in-depth inquiry, whereas a negative perspective leads to advocacy and in our view less learning potential. Thus, the positive perspective we take in this “Point” piece is to identify and make a deep inquiry into the major issues and questions surrounding positive organizational behavior (POB). We consciously try to avoid taking an advocacy position. Specifically, after first setting the stage with the background and status of POB, we draw from the lessons that can be learned from positive psychology and then make an inquiry into “Why POB? ” and exactly “What is POB? ” The article concludes with further inquiry into the role the negative does and can play, and finally how POB relates to our recent work in authentic leadership development.

Dependency Grammar and Dependency Parsing

Despite a long and venerable tradition in descriptive linguistics, dependency grammar has until recently played a fairly marginal role both in theoretical linguistics and in natural language processing. The increasing interest in dependency-based representations in natural language parsing in recent years appears to be motivated both by the potential usefulness of bilexical relations in disambiguation and by the gains in efficiency that result from the more constrained parsing problem for these representations. In this paper, we will review the state of the art in dependency-based parsing, starting with the theoretical foundations of dependency grammar and moving on to consider both grammar-driven and data-driven methods for dependency parsing. We will limit our attention to systems for dependency parsing in a narrow sense, i.e. systems where the analysis assigned to an input sentence takes the form of a dependency structure. This means that we will not discuss systems that exploit dependency relations for the construction of another type of representation, such as the head-driven parsing models of Collins (1997, 1999). Moreover, we will restrict ourselves to systems for full parsing, which means that we will not deal with systems that produce a partial or underspecified representation of dependency structure, such as Constraint Grammar parsers (Karlsson, 1990; Karlsson et al., 1995).
Analysis of DDoS Detection Systems

While there are plenty of papers describing algorithms for detecting distributed denial of service (DDoS) attacks, here an introduction to the considerations preceding such an implementation is given. Therefore, a brief history of and introduction to DDoS attacks is given, showing that these kind of attacks are nearly two decades old. It is also depicted that most algorithms used for the detection of DDoS attacks are outlier detection algorithms, such that intrusion detection can be seen as a part of the KDD research field. It is then pointed out that no well known and up-to-date test cases for DDoS detection system are known. To overcome this problem in a way that allows to test algorithms as well as making results reproducible for others we advice using a simulator for DDoS attacks. The challenge of detecting denial of service attacks in real time is addressed by presenting two recently published methods that try to solve the performance problem in very different ways. We compare both approaches and finally summarise the conclusions drawn from this, especially that methods concentrating on one network traffic parameter only are not able to detect all kinds of distributed denial of service attacks.
Moving to Greener Pastures? Multinationals and the Pollution Haven Hypothesis

This paper discusses program evaluation for ProJoven, the Peruvian youth labor training program. Complementing detailed fieldwork, the econometric work implements a two-stage matching procedure on propensity scores, gender and labor income. This allows identification of differentiated program impacts on males and females and attacks the problem of Ashenfelter's Dips. The evaluation shows substantial differences in ProJoven's impact for males and females. Eighteen months after participation in the program, employment rates for females improve by about 15 percent (while employment for males reduces by 11 percent), gender occupational segregation reduces by 30 percent, and females' labor income improves by 93 percent (while males' earnings increase by 11 percent). Nonetheless, gender equality promotion represents only 1.5 percent of ProJoven's budget. These results suggest that labor-training programs that promote equal gender participation have disproportionately positive effects on outcomes for women trainees in a labor market with substantial gender differences.
On Orthogonal Covers of ~ K N

An orthogonal cover of the complete digraph ~ K n is a collection of n spanning subgraphs ~ K n such that-every directed edge of ~ K n belongs to exactly 1 of the ~ G i 's and-for every two digraphs ~ G i and ~ G j (i 6 = j) there is a unique two-element set fa; bg of vertices such that ~ G i contains the directed edge (a; b) and ~ G j contains the directed edge (b; a). It is proven that there exists an orthogonal cover of ~ K n , where the ~ G i 's consist of short directed cycles, for all n 4; with a few possible exceptions. We conclude by establishing the existence of an orthogonal cover of ~ K n , where the ~ G i 's have maximum outdegree and maximum indegree one, for all n 2. This gives another proof of the directed version of a problem of Chung and West.
Clinical relevance for the fact that GnRH antagonists do not downregulate the GnRH receptor

Sir, It has been more than 10 years since safe and effective gonadotrophinreleasing hormone (GnRH) antagonists became available for use in controlled ovarian stimulation (COS) cycles. In 2000, we noted that there was an inconsistency with how researchers in this field describe the mechanism of action of GnRH antagonists (Mannaerts and Gordon, 2000). Unfortunately, there is continued misuse of terminology describing the differences in the mechanism of action of the two classes of GnRH analogs in articles published in Human Reproduction and Fertility and Sterility (Huang et al., 2012; Youssef et al., 2012). References to ‘GnRH antagonist down-regulated cycles’ or ‘pituitaries desensitized to GnRH antagonists’ are inaccurate and lead to confusion. GnRH agonists have been used clinically since the mid-1980s to prevent the occurrence of a surge in LH, which may occur prematurely before the leading follicle reaches the optimum diameter for triggering ovulation with human chorionic gonadotrophin (Gordon and Hodgen, 1991). GnRH agonists reduce the incidence of a premature LH surge by suppressing gonadotrophin levels via pituitary desensitization and down-regulation following an initial short period of gonadotrophin hypersecretion (Conn and Crowley, 1991). Unlike GnRH agonists, GnRH antagonists cause an immediate and rapid inhibition of LH release by competitively blocking GnRH receptors in the anterior pituitary gland and thereby preventing endogenous GnRH from inducing LH and FSH release from the pituitary cells (Gordon and Hodgen, 1991). GnRH antagonists have the formal regulatory indication of prevention (inhibition in the USA) of premature LH surges in women undergoing COS prior to IVF/ICSI in most countries. The fundamental mechanistic difference between GnRH agonists and antagonists has gained clinical significance as it has become apparent that ovarian hyperstimulation syndrome can largely be avoided by using a GnRH agonist bolus to trigger an endogenous LH/FSH surge to produce final oocyte maturation (Ron-El et al., 2000; Humaidan et al., 2010; Devroey et al., 2011). Importantly, this can only be achieved in a GnRH antagonist protocol as an LH/FSH surge cannot be induced with a GnRH agonist if the pituitary is down-regulated and/or desensitized. Hence, in an attempt to simplify things moving forward we propose that the terms ‘pituitary inhibition’ or ‘pituitary suppression’ are used to signify the actions of GnRH antagonists and the terms ‘downregulation’ and ‘desensitization’ are used to define the actions of GnRH agonists.

Imitation learning of car driving skills with decision trees and random forests

Abstract Machine learning is an appealing and useful approach to creating vehicle control algorithms, both for simulated and real vehicles. One common learning scenario that is often possible to apply is learning by imitation, in which the behavior of an exemplary driver provides training instances for a supervised learning algorithm. This article follows this approach in the domain of simulated car racing, using the TORCS simulator. In contrast to most prior work on imitation learning, a symbolic decision tree knowledge representation is adopted, which combines potentially high accuracy with human readability, an advantage that can be important in many applications. Decision trees are demonstrated to be capable of representing high quality control models, reaching the performance level of sophisticated pre-designed algorithms. This is achieved by enhancing the basic imitation learning scenario to include active retraining, automatically triggered on control failures. It is also demonstrated how better stability and generalization can be achieved by sacrificing human-readability and using decision tree model ensembles. The methodology for learning control models contributed by this article can be hopefully applied to solve real-world control tasks, as well as to develop video game bots
The Swift/BAT High-Latitude Survey: First Results

We present preliminary results from the first 3 months of the Swift Burst Alert Telescope (BAT) high Galactic latitude survey in the 14-195 keV band. The survey reaches a flux of ~10-11 ergs cm-2 s-1 and has ~2. ′7 (90% confidence) positional uncertainties for the faintest sources. This represents the most sensitive survey to date in this energy band. These data confirm the conjectures that a high-energy-selected active galactic nucleus (AGN) sample would have very different properties from those selected in other bands and that it represents a "true" sample of the AGN population. We have identified 86% of the 66 high-latitude sources. Twelve are Galactic-type sources, and 44 can be identified with previously known AGNs. All but five of the AGNs have archival X-ray spectra, enabling us to estimate the line-of-sight column densities and other spectral properties. Both of the z > 0.11 objects are blazars. The median redshift of the others (excluding radio-loud objects) is 0.012. We find that the column density distribution of these AGNs is bimodal, with 64% of the nonblazar sources having column densities NH ≥ 1022 cm-2. None of the sources with log LX > 43.5 (cgs units) show high column densities, and very few of the lower LX sources have low column densities. Based on these data, we expect the final BAT catalog to have >200 AGNs and reach fluxes of less than ~10-11 ergs cm-2 s-1 over the entire sky.
Is Distance Dying at Last? Falling Home Bias in Fixed Effects Models of Patent Citations

We examine the 'home bias' of international knowledge spillovers as measured by the speed of patent citations (i.e. knowledge spreads slowly over international boundaries). We present the first compelling econometric evidence that the geographical localization of knowledge spillovers has fallen over time, as we would expect from the dramatic fall in communication and travel costs. Our proposed estimator controls for correlated fixed effects and censoring in duration models and we apply it to data on over two million citations between 1975 and 1999. Home bias declines substantially when we control for fixed effects: there is practically no home bias for the more 'modern' sectors such as pharmaceuticals and information/communication technologies.
Willingness to Use the Internet to Seek Information on HIV Prevention and Care among Men Who Have Sex with Men in Ho Chi Minh City, Vietnam

Background In Vietnam, men who have sex with men (MSM) are highly affected by HIV and need new targeted HIV prevention strategies. Objectives To assess the willingness to use the Internet to seek information on HIV prevention and care and associated factors among MSM in Ho Chi Minh City. Methods A descriptive cross-sectional study was conducted in 2012. Participants were recruited using a convenience sampling method in venues most frequented by MSM and completed a self-administered questionnaire. Logistic regression models were performed to estimate factors associated with the willingness to use the Internet to seek information on HIV prevention and care. Results A total of 358 MSM were approached for the survey and 222 questionnaires (62.0%) were eligible for analyses. Overall, 76.1% of the respondents reported that they were willing to use the Internet to seek information on HIV prevention and care. A number of male partners in last year less than or equal to 3 (Adjusted Odds Ratio: 3.07, 95% Confidence interval: 1.40–6.73), a history of STI screening (4.10, 1.02–16.48) and HIV testing (3.23, 1.20–8.64) and having ever sought a male sexual partner through the Internet (3.56, 1.55–8.18) were significantly positively associated with the willingness to use the Internet to seek information on HIV prevention and care. Conclusion The MSM interviewed in Ho Chi Minh City reported a high willingness to use the Internet to seek information on HIV prevention and care. In a context where new media are increasingly considered as promising options for reaching this HIV risk group, further research should be conducted on developing and testing tailored online tools adapted to the needs of Vietnamese MSM.
INTIMATE VIOLENCE AGAINST WOMEN – Systematized Literature Review

ABSTRACT Objectives: To analyze scientific productions on intimate violence against women, besides pointing out the representations of this event from the perspective of nursing professionals relating risk factors to the patient in health units. Method: Systematic review of the literature of 10 scientific articles published between the years 2011 to 2017 in the LILACS, MEDLINE and SCIELO databases, which met the inclusion and exclusion criteria of the study. Outcome: The publications have raised issues related to the treatment of nursing in the care of women victims of intimate violence, pointing out their main interventions. Conclusion: Through the evidence of intimate violence against women diagnosed by care in health units, the articles describe that in addition to this care, professionals need to deepen the understanding of how to act in the face of this phenomenon. Among the actions it is necessary that preventive measures be created by the legislation to avoid such violence, which culminates in crimes of feminicide. Examples include: the feeling of anguish may be related to the situation of the woman, but also to the difficulties of the nurses to deal with the issue; nurses are well acquainted with the definition of violence, but they do not know the important epidemiological characteristics of violence against women, which may be a barrier for nurses to attend to women at risk. Keywords: Violence. Woman. Nursing. Cheers.
The Effect of Gender Equality on International Soccer Performance

In this paper, we propose a new estimation strategy that uses the variation in success between the male and the female national soccer team within a country to identify the causal impact of gender equality on women's soccer performance. In particular, we analyze whether within-country variations in labor force participation rates and life expectancies between the genders, which serve as measures for the countryOs gender equality, are able to explain differences in the international success of male and female national soccer teams. Our results reveal that differences in male and female labor force participation rates and life expectancies are able to explain the international soccer performance of female teams, but not that of male teams, suggesting that gender equality is an important driver of female sport success.
