TL;DR: In this article, it was shown that ultracompact objects with large rotation have a strong ergoregion instability when rapidly spinning, which can be detected by next-generation LIGO or LISA.
Abstract: Most of the properties of black holes can be mimicked by horizonless compact objects such as gravastars and boson stars. We show that these ultracompact objects develop a strong ergoregion instability when rapidly spinning. Instability time scales can be of the order of 0.1 seconds to 1 week for objects with mass $M=1\ensuremath{-}{10}^{6}{M}_{\ensuremath{\bigodot}}$ and angular momentum $Jg0.4{M}^{2}$. This provides a strong indication that ultracompact objects with large rotation are black holes. Explosive events due to ergoregion instability have a well-defined gravitational-wave signature. These events could be detected by next-generation gravitational-wave detectors such as Advanced LIGO or LISA.

12 Dec 2007TL;DR: The aim of this paper is to study the fusion at feature extraction level for face and fingerprint biometrics by extracting independent feature pointsets from the two modalities, and making the two pointsets compatible for concatenation.
Abstract: The aim of this paper is to study the fusion at feature extraction level for face and fingerprint biometrics. The proposed approach is based on the fusion of the two traits by extracting independent feature pointsets from the two modalities, and making the two pointsets compatible for concatenation. Moreover, to handle the 'problem of curse of dimensionality', the feature pointsets are properly reduced in dimension. Different feature reduction techniques are implemented, prior and after the feature pointsets fusion, and the results are duly recorded. The fused feature pointset for the database and the query face and fingerprint images are matched using techniques based on either the point pattern matching, or the Delaunay triangulation. Comparative experiments are conducted on chimeric and real databases, to assess the actual advantage of the fusion performed at the feature extraction level, in comparison to the matching score level.

TL;DR: Two variants associated with follicular lymphoma at 6p21.32 are identified, supporting the idea that major histocompatibility complex genetic variation influences follicle lymphoma susceptibility.
Abstract: To identify susceptibility loci for non-Hodgkin lymphoma subtypes, we conducted a three-stage genome-wide association study. We identified two variants associated with follicular lymphoma at 6p21.32 (rs10484561, combined P = 1.12 x 10(-29) and rs7755224, combined P = 2.00 x 10(-19); r(2) = 1.0), supporting the idea that major histocompatibility complex genetic variation influences follicular lymphoma susceptibility. We also found confirmatory evidence of a previously reported association between chronic lymphocytic leukemia/small lymphocytic lymphoma and rs735665 (combined P = 4.24 x 10(-9)).

TL;DR: In this article, the authors hypothesized that job autonomy and intrinsic motivation were key exogenous variables positively related to affective commitment, which in turn is negatively related to turnover intention, by performing a mediating role.
Abstract: Drawing on Self-Determination and Work Characteristics theories, we hypothesized that job autonomy and intrinsic motivation were key exogenous variables positively related to affective commitment, which in turn is negatively related to turnover intention, by performing a mediating role. A sample of 442 nurses has been involved in this research. Through the cross-validation technique, the results showed that the hypotheses of this study were supported and affective commitment completely mediated the relationships between job autonomy, intrinsic work motivation and turnover intention. These findings have important implications for healthcare organizations by helping to promote effective work environments and major opportunities of responsibility to workers to develop their own activity. Conclusions were examined considering practical implications for organizations, employees and the need for further researches.

TL;DR: Pediatric BPD is familial more often than is adult‐onset BPD, may be associated with a premorbid cyclothymic or hyperthymic temperament, and can be precipitated by antidepressant treatment.
Abstract: Bipolar disorder (BPD), probably the most prevalent psychotic disorder in adults, has been relatively neglected or controversial in children and adolescents over the past century. We reviewed the literature on early-onset BPD.* Estimates of prevalence, particularly before puberty, are limited by historical biases against pediatric mood disorders and by formidable diagnostic complexity and comorbidity. Although clinical features of pediatric and adult BPD have similarities, pediatric cases probably cannot be defined solely by features characteristic of adult cases. Onset was before age 20 years in at least 25% of reported BPD cases, with some increase in this incidence over the past century. Pediatric BPD is familial more often than is adult-onset BPD, may be associated with a premorbid cyclothymic or hyperthymic temperament, and can be precipitated by antidepressant treatment. Pediatric BPD episodes frequently include irritability, dysphoria, or psychotic symptoms; they are commonly chronic and carry high...
