Discovery of the Narrow-Line Seyfert 1 Galaxy Markarian 335 in a Historical Low X-Ray Flux State

We report the discovery of the narrow-line Seyfert 1 galaxy Mrk 335 in an extremely low X-ray state. A comparison of Swift observations obtained in 2007 May and June/July with all previous X-ray observations between 1971 and 2006 show the AGN to have diminished in flux by a factor of more than 30, the lowest X-ray flux Mrk 335 has ever been observed in. The Swift observations show an extremely hard X-ray spectrum at energies above 2 keV. Possible interpretations include partial-covering absorption or X-ray reflection from the disk. In this Letter we consider the partial-covering interpretation. The Swift observations can be well fit by a strong partial-covering absorber with varying absorption column density [NH = (1-4) × 1023 cm-2] and a covering fraction fc = 0.9-1. When corrected for intrinsic absorption, the X-ray flux of Mrk 335 varies by only factors of 4-6. In the UV Mrk 335 shows variability on the order of 0.2 mag. We discuss the similarity of Mrk 335 to the highly variable NLS1 WPVS 007, and speculate about a possible link between NLS1 galaxies and broad-absorption-line quasars.
Job Burnout Rate among Zahedan University of Medical Sciences Staff

In case the individual is not capable of resisting stressful conditions, s/he would be exposed to psychologicalphysical- behavioral symptoms and effects. One of the most important outcomes resulting from the long-lasting psychological pressures is the job burnout. The present study’s objective is to survey the job burnout rate among Zahedan University of Medical Sciences staff. The present study is a descriptive-analytical cross-sectional research which has been conducted on 172 individuals among Zahedan University of Medical Sciences staff. To collect the required information a two-part questionnaire was used. Data were analyzed by the use of SPSS 19 software and descriptive statistics, Pearson correlation, variance analysis, and independent t-test. The individuals’ average age was 36.49 6 9.85; 106 individuals were women, and 146 individuals were married. The job burnout mean score was 58.46 6 10.17, and the mean scores for emotional exhaustion, depersonalization, and reduced personal accomplishment were 23.21 6 4.92, 10.30 6 3.56, and 21.51 6 4.68, respectively. The relationship between gender and marital status with job burnout and each of its indicators and components was not statistically significant (p i® 0.05). The relationship between age and job burnout (p 5 0.005) and emotional exhaustion (p 5 0.05), depersonalization (p 5 0.04), and reduced personal accomplishment (p 5 0.003) was statistically significant. The existence of varied levels of job burnout in Zahedan University of Medical Sciences staff makes it necessary to pay careful attention to staff health and the creation of supporting-system facilities to reduce job weariness and exhaustion.
Language Resources for a Network-based Dictionary

In order to facilitate the use of a dictionary for language production and language learning we propose the construction of a new network-based electronic dictionary along the lines of Zock (2002). However, contrary to Zock who proposes just a paradigmatic network with information about the various ways in which words are similar we would like to present several existing language resources (LRs) which will be integrated in such a network resulting in more linguistic levels than one with paradigmatically associated words. We argue that just as the mental lexicon exhibits various, possibly interwoven layers of networks, electronic LRs containing syntagmatic, morphological and phonological information need to be integrated into an associative electronic dictionary.
Terrorism Event Classification Using Fuzzy Inference Systems

Terrorism has led to many problems in Thai societies, not only property damage but also civilian casualties. Predicting terrorism activities in advance can help prepare and manage risk from sabotage by these activities. This paper proposes a framework focusing on event classification in terrorism domain using fuzzy inference systems (FISs). Each FIS is a decision-making model combining fuzzy logic and approximate reasoning. It is generated in five main parts: the input interface, the fuzzification interface, knowledge base unit, decision making unit and output defuzzification interface. Adaptive neuro-fuzzy inference system (ANFIS) is a FIS model adapted by combining the fuzzy logic and neural network. The ANFIS utilizes automatic identification of fuzzy logic rules and adjustment of membership function (MF). Moreover, neural network can directly learn from data set to construct fuzzy logic rules and MF implemented in various applications. FIS settings are evaluated based on two comparisons. The first evaluation is the comparison between unstructured and structured events using the same FIS setting. The second comparison is the model settings between FIS and ANFIS for classifying structured events. The data set consists of news articles related to terrorism events in three southern provinces of Thailand. The experimental results show that the classification performance of the FIS resulting from structured events achieves satisfactory accuracy and is better than the unstructured events. In addition, the classification of structured events using ANFIS gives higher performance than the events using only FIS in the prediction of terrorism events.
Closed-String Tachyons and the Hagedorn Transition in AdS Space

We discuss some aspects of the behaviour of a string gas at the Hagedorn temperature from a euclidean point of view. Using AdS space as an infrared regulator, the Hagedorn tachyon can be efiectively quasi-localized and its dynamics controled by a flnite energetic balance. We propose that the ofi-shell RG ∞ow matches to an euclidean AdS black hole geometry in a generalization of the string/black-hole correspondence principle. The flnal stage of the RG ∞ow can be interpreted semiclassically as the growth of a cool black hole in a hotter radiation bath. The end-point of the condensation is the large euclidean AdS black hole, and the part of spacetime behind the horizon has been removed. In the ∞at-space limit, holography is manifest by the system creating its own transverse screen at inflnity. This leads to an argument, based on the energetics of the system, explaining why the non-supersymmetric type-0A string theory decays into the supersymmetric type-IIB vacuum. We also suggest a notion of 'boundary entropy', the value of which decreases along the line of ∞ow.
Issues Around Aligning Theory, Research and Practice in Social Work Education

Issues Around Aligning Theory, Research and Practice in Social Work Education provides a reflection on social work education with a slant towards an Afrocentric approach, aiming to facilitate strong reflective thinking and to address local realities about social work education on the African continent as well as in broader global contexts. This volume focuses on issues around aligning theory, research and practice in social work education. A significant contribution is made here to the scholarly understanding of opportunities to sustain the academic discourse on social work education. Social work as a profession and a social science discipline is dynamic, and it ought to meet the challenges of the realities of the societies in which it serves, given the history of the changing society of South Africa from apartheid to democracy. Over the years, social work education and training has undergone tremendous curricular changes with the enactment of the White Paper for Social Welfare and the national review, respectively, by the South African Council for Social Services Professions (SACSSP) and the Council on Higher Education (CHE) for the re-accreditation of all Bachelor of Social Work (BSW) programmes in South Africa fulfilling the prescripts of the Higher Education Act (No. 101 of 1997, as amended) and Social Service Professions Act (No. 110 of 1978). It is worth mentioning that the curricular changes will also continue with the current reviewing of Social Service Professions Act (No. 110 of 1978), as amended, which is underway in South Africa. This book is really ground-breaking! The Afrocentric perspective on social work practice contributes to the current discourse on decolonisation of social work teaching and practice. From a methodological perspective, the book is premised on multi-, inter- and trans-disciplining in social sciences. It covers aspects of social work education and practice through research (narrative, qualitative, African methodology, secondary data analysis, etc.), engendering values and ethics, report writing, supervision in fieldwork as well as exchange programmes and international service-learning, addressing a number of concepts such as cultural competency, cultural awareness and sensitivity are addressed.
Ubiquitous Pokémon Go: Human–Environment Relationships and the Location-Based Augmented Reality Game

This study explores the complexity of the connection between Pokémon Go play experience and players’ affection toward their physical surroundings from the environmental psychology and the media entertainment perspectives. The survey results of a stratified sample of 1,088 respondents showed that four dimensions of perceived realism—simulational realism, freedom of choice, integrated presence, and perceptual pervasiveness—positively influenced game enjoyment. Co-presence positively predicted game enjoyment while perceived crowding was negatively related to game enjoyment. Game involvement partially mediated the relationship between co-presence and game enjoyment, and game involvement also mediated the relationship between game enjoyment and place attachment. Theoretical implications on linking human behaviors and their affectional connections to physical places via the virtual gaming world are also discussed.
Fredholmness of Singular Integral Operators with Piecewise Continuous Coefficients on Weighted Banach Function Spaces

We prove necessary conditions for Fredholmness of singular integral operators with piecewise continuous coefficients on weighted Banach function spaces. These conditions are formulated in terms of indices of submultiplicative functions associated with local properties of the space, of the curve, and of the weight. As an example, we consider weighted Nakano spaces $L^{p(\cdot)}_w$ (weighted Lebesgue spaces with variable exponent). Moreover, our necessary conditions become also sufficient for weighted Nakano spaces over nice curves whenever $w$ is a Khvedelidze weight, and the variable exponent $p(t)$ satisfies the estimate $|p(\tau)-p(t)|\le A/(-\log|\tau-t|)$.
Comparative Analyses of Response Surface Methodology and Artificial Neural Network on Medium Optimization for Tetraselmis sp. FTC209 Grown under Mixotrophic Condition

Mixotrophic metabolism was evaluated as an option to augment the growth and lipid production of marine microalga Tetraselmis sp. FTC 209. In this study, a five-level three-factor central composite design (CCD) was implemented in order to enrich the W-30 algal growth medium. Response surface methodology (RSM) was employed to model the effect of three medium variables, that is, glucose (organic C source), NaNO3 (primary N source), and yeast extract (supplementary N, amino acids, and vitamins) on biomass concentration, X max, and lipid yield, P max/X max. RSM capability was also weighed against an artificial neural network (ANN) approach for predicting a composition that would result in maximum lipid productivity, Prlipid. A quadratic regression from RSM and a Levenberg-Marquardt trained ANN network composed of 10 hidden neurons eventually produced comparable results, albeit ANN formulation was observed to yield higher values of response outputs. Finalized glucose (24.05 g/L), NaNO3 (4.70 g/L), and yeast extract (0.93 g/L) concentration, affected an increase of X max to 12.38 g/L and lipid a accumulation of 195.77 mg/g dcw. This contributed to a lipid productivity of 173.11 mg/L per day in the course of two-week cultivation.
Locally Affine Sparse-to-Dense Matching for Motion and Occlusion Estimation

Estimating a dense correspondence field between successive video frames, under large displacement, is important in many visual learning and recognition tasks. We propose a novel sparse-to-dense matching method for motion field estimation and occlusion detection. As an alternative to the current coarse-to-fine approaches from the optical flow literature, we start from the higher level of sparse matching with rich appearance and geometric constraints collected over extended neighborhoods, using an occlusion aware, locally affine model. Then, we move towards the simpler, but denser classic flow field model, with an interpolation procedure that offers a natural transition between the sparse and the dense correspondence fields. We experimentally demonstrate that our appearance features and our complex geometric constraints permit the correct motion estimation even in difficult cases of large displacements and significant appearance changes. We also propose a novel classification method for occlusion detection that works in conjunction with the sparse-to-dense matching model. We validate our approach on the newly released Sintel dataset and obtain state-of-the-art results.
A New Descriptor for 2D Depth Image Indexing and 3D Model Retrieval

We present here a new descriptor for depth images adapted to 2D/3D model matching and retrieving. We propose a representation of a 3D model by 20 depth images rendered from the vertices of a regular dodecahedron. One depth image of a 3D model is associated to a set of depth lines which will be afterward transformed into sequences. The depth sequence information provides a more accurate description of 3D shape boundaries than using other 2D shape descriptors. Similarity computing is performed when dynamic programming distance (DPD) is used to compare the depth line descriptors. The DPD leads to an accurate matching of sequences even in the presence of local shifting on the shape. Results on a large 3D database show efficiency of our 2D/3D approach.
Neuromuscular Performance Characteristics in Elite Female Athletes

The purpose of this research was to identify possible predisposing neuromuscular factors for knee injuries, particularly anterior cruciate ligament tears in female athletes by investigating anterior knee laxity, lower extremity muscle strength, endurance, muscle reaction time, and muscle recruitment order in response to anterior tibial translation. We recruited four subject groups: elite female (N = 40) and male (N = 60) athletes and sex-matched nonathletic controls ( N = 40). All participants underwent a subjective evaluation of knee function, arthrometer measurement of anterior tibial translation, isokinetic dynamometer strength and endurance tests at 60 and 240 deg/sec, and anterior tibial translation stress tests. Dynamic stress testing of muscles demonstrated less anterior tibial translation in the knees of the athletes (both men and women) com pared with the nonathletic controls. Female athletes and controls demonstrated more anterior tibial laxity than their male counterparts and significantly less mus cle strength and endurance. Compared with the male athletes, the female athletes took significantly longer to generate maximum hamstring muscle torque during isokinetic testing. Although no significant differences were found in either spinal or cortical muscle reaction times, the muscle recruitment order in some female athletes was markedly different. The female athletes appeared to rely more on their quadriceps muscles in response to anterior tibial translation; the three other test groups relied more on their hamstring muscles for initial knee stabilization.
Profile of children and adolescents admitted to a Burn Care Unit in the countryside of the state of São Paulo☆

Objective: To describe the profile of pediatric burn victims hospitalized at Hospital-Escola Padre Albino (HEPA), in Catanduva, São Paulo, Brazil. Methods: This was a cross-sectional, retrospective study analyzing 446 medical records of patient aged 0-18 years old hospitalized in the Burn Care Unit of HEPA, from 2002 to 2012. The following variables were recorded: demographic data, skin burn causes, lesions characteristics, complications, surgical procedures, length of hospital stay, and outcome. Descriptive statistics were used. Results: 382 patients with full medical records were included in the study. Burns were more frequent in males (64.4%) and in children aged less than 6 years (52.9%). Most accidents occurred at home (67.3%) and hot liquids were responsible for 47.1% of them. Mean burnt body surface was 18% and the most affected body areas were chest and limbs. First- and second-degree burns were observed in 64.4% of the cases. Secondary infection and surgical procedures occurred in 6.5% and 45.0% of the patients, respectively. Mean length of hospital stay was 9.8 days. The mortality rate was 1.6%. Conclusions: Preschool children were the main victims of burns occurring at home, representing the largest contingent of hospitalizations due to this cause in individuals aged < 18 years. It is important to develop strategies to alert parents and general society through educational programs and preventive campaigns.
Benchmarking Asset Correlations

Among the most crucial input parameters for credit portfolio risk models are the co-movements of default risks. Due to limited empirical evidence about the magnitude of correlations the New Basel Capital Accord sets standard requirements for calculating regulatory capital requirements, e.g. in the Consultative Document as of April 2003 asset correlations for sovereigns, banks and corporates between 12% and 24% depending on default probabilities are assumed. The present contribution shows how correlations can be estimated within the framework of the Basel II model. Using Default data from the G7 countries it is shown that asset correlations are much lower than broadly assumed. This may have valuable consequences for backtesting of PD forecasts carried out by banks and supervisors. Furthermore it is shown how current credit risk models can be parameterized with our estimates. We find that the differences between the model outcomes may become even more negligible than found up to now, thus reducing model risk.
Publication bias in clinical trials due to statistical significance or direction of trial results.

BACKGROUND The tendency for authors to submit, and of journals to accept, manuscripts for publication based on the direction or strength of the study findings has been termed publication bias. OBJECTIVES To assess the extent to which publication of a cohort of clinical trials is influenced by the statistical significance, perceived importance, or direction of their results. SEARCH STRATEGY We searched the Cochrane Methodology Register (The Cochrane Library [Online] Issue 2, 2007), MEDLINE (1950 to March Week 2 2007), EMBASE (1980 to Week 11 2007) and Ovid MEDLINE In-Process & Other Non-Indexed Citations (March 21 2007). We also searched the Science Citation Index (April 2007), checked reference lists of relevant articles and contacted researchers to identify additional studies. SELECTION CRITERIA Studies containing analyses of the association between publication and the statistical significance or direction of the results (trial findings), for a cohort of registered clinical trials. DATA COLLECTION AND ANALYSIS Two authors independently extracted data. We classified findings as either positive (defined as results classified by the investigators as statistically significant (P < 0.05), or perceived as striking or important, or showing a positive direction of effect) or negative (findings that were not statistically significant (P >/= 0.05), or perceived as unimportant, or showing a negative or null direction in effect). We extracted information on other potential risk factors for failure to publish, when these data were available. MAIN RESULTS Five studies were included. Trials with positive findings were more likely to be published than trials with negative or null findings (odds ratio 3.90; 95% confidence interval 2.68 to 5.68). This corresponds to a risk ratio of 1.78 (95% CI 1.58 to 1.95), assuming that 41% of negative trials are published (the median among the included studies, range = 11% to 85%). In absolute terms, this means that if 41% of negative trials are published, we would expect that 73% of positive trials would be published.Two studies assessed time to publication and showed that trials with positive findings tended to be published after four to five years compared to those with negative findings, which were published after six to eight years. Three studies found no statistically significant association between sample size and publication. One study found no significant association between either funding mechanism, investigator rank, or sex and publication. AUTHORS' CONCLUSIONS Trials with positive findings are published more often, and more quickly, than trials with negative findings.
An inverse source problem for Maxwell's equations in anisotropic media

In this article, we consider nonstationary Maxwell's equations in an anisotropic medium in the (x 1, x 2, x 3)-space, where equations of the divergences of electric and magnetic flux densities are also unknown. Then we discuss an inverse problem of determining the x 3-independent components of the electric current density from observations on the plane x 3 = 0 over a time interval. Our main aim is, study conditional stability in the inverse problem provided the permittivity and the permeability are independent of x 3. The main tool is a new Carleman estimate.
Comparison of the Efficacy of Entecavir and Tenofovir in Nucleos(T)ide Analogue-Experienced Chronic Hepatitis B Patients

The efficacy of entecavir (ETV) and tenofovir (TDF) for the treatment of nucleos(t)ide analogue (NA)-experienced chronic hepatitis B (CHB) patients has been little studied. Here, we compare the efficacy of both ETV and TDF in NA-experienced CHB patients without detectable genotypic resistance. This retrospective cohort study included consecutive NA-experienced patients who had neither current nor previous genotypic resistance and had received ETV or TDF for at least 6 months. Overall, 202 patients (146 patients in the ETV group and 56 in the TDF group) were analyzed. The cumulative probabilities of complete virologic suppression (CVS) at month 12 were 76.1% in the ETV group and 95.0% in the TDF group (P<0.001), respectively. The TDF-treated group achieved CVS more rapidly than the ETV group for both Hepatitis B e antigen (HBeAg)-negative and -positive patients (P = 0.006 and < 0.001, respectively), and for those with both low (< 2,000 IU/mL) and high (≥ 2,000 IU/mL) HBV DNA levels (P = 0.01 and 0.002, respectively). TDF group had an increased probability of achieving CVS (hazard ratio, 2.242; 95% confidence interval, 1.587–3.165; P = 0.001), after adjustment for HBV DNA level, the presence of HBeAg, and a history of CVS during prior treatment. During the treatment period, 23 patients (15.8%) in the ETV group developed virologic breakthrough, compared to none in the TDF group. The cumulative probabilities of developing virologic breakthrough and ETV-resistance at month 24 were 9.7% and 5.3%, respectively. In conclusion, TDF is preferable to ETV for achieving CVS in NA-experienced CHB patients without genotypic resistance.
