Automated production of true-cased punctuated subtitles for weather and news broadcasts

Providing subtitling for multimedia content is a highly costly process. Any system aimed at automating at least part of this process may therefore yield significant economic benefits for content providers. In this paper, we present an integrated automatic system capable of automatically subtitling weather forecasts and news broadcasts. In this system, a number of different modules are stringed together, each performing a single processing step in the pipeline. An ASR (Automatic Speech Recognition) module first converts raw audio into an uninterrupted stream of written words. A decision tree classifier then marks sentence boundaries in the resulting word sequence. Finally, a SMT (Statistical Machine Translation) module ‘translates’ the resulting sentences into punctuated true-cased text. The system has been developed in close cooperation with Red Bee Media and will be deployed in their commercial production pipeline.
Unified Capacity Limit of Non-Coherent Wideband Fading Channels

In non-coherent wideband fading channels, where energy rather than spectrum is the limiting resource, peaky and non-peaky signaling schemes have long been considered species apart, as the first approaches asymptotically the capacity of a wideband AWGN channel with the same average SNR, whereas the second reaches a peak rate at some finite critical bandwidth and then falls to zero as bandwidth grows to infinity. In this paper, it is shown that this distinction is in fact an artifact of the limited attention paid in the past to the product between the bandwidth and the fraction of time it is in use. This fundamental quantity, called bandwidth occupancy, measures average bandwidth usage over time. For all signaling schemes with the same bandwidth occupancy, achievable rates approach to the wideband AWGN capacity within the same gap as the bandwidth occupancy approaches its critical value, and decrease to zero as the occupancy goes to infinity. This unified analysis produces quantitative closed-form expressions for the ideal bandwidth occupancy, recovers the existing capacity results for (non-) peaky signaling schemes, and unveils a tradeoff between the accuracy of approximating capacity with a generalized Taylor polynomial and the accuracy with which the optimal bandwidth occupancy can be bounded.
Clinicopathological Significance of Expression of Tspan-1, Jab1 and p27 in Human Hepatocellular Carcinoma

The aim of this study was to investigate the expression of Tspan-1, Jab1 and p27 in human hepatocellular carcinoma (HCC) and their clinicopathological significance. The expression of Tspan-1, Jab1 and p27 was detected in HCC tissues, the tissues around cancer (76 cases), and the normal tissues around the liver hemangiomas (10 cases). The overexpression of Tspan-1 and Jab1 was found in HCC tissues, positively correlated with clinical stage and negatively correlated with survival rate. The expression of p27 was found inversely linked to which of Tspan-1 and Jab1. In conclusion, the expression of Tspan-1, Jab1 and p27 is significantly associated with development of HCC. Overexpression of Tspan-1 and Jab1 suggests poor prognosis but overexpression of p27 may expect good prognosis for patients with HCC.
Investigating the Features of the M170 in Congenital Prosopagnosia

Face perception generates specific neural activity as early as 170 ms post-stimulus onset, termed the M170 when measured with Magnetoencephalography (MEG). We examined the M170 in six people with congenital prosopagnosia (CP) and 11 typical controls. Previous research indicates that there are two neural generators for the M170 (one within the right lateral occipital area – rLO and one within the right fusiform gyrus – rFG), and in the current study we explored whether these sources reflect the processing of different types of information. Individuals with CP showed face-selective M170 responses within the rLO and right rFG, which did not differ in magnitude to those of the controls. To examine possible links between neural activity and behavior we correlated the CPs’ MEG activity generated within rLO and rFG with their face perception skills. The rLO-M170 correlated with holistic/configural face processing, whereas the rFG-M170 correlated with featural processing. Hence, the results of our study demonstrate that individuals with CP can show an M170 that is within the normal range, and that the M170 in the rLO and rFG are involved in different aspects of face processing.
Lectures on Foliation Dynamics: Barcelona 2010

This survey is based on a series of five lectures, given May 3--7, 2010, at the Centre de Recerca Matematica, Barcelona. The goal of the lectures was to present aspects of the theory of foliation dynamical systems which have particular importance for the classification of foliations of compact manifolds. The lectures emphasized intuitive concepts and informal discussion, while taking the reader into topics of active research in this subject. These notes update and expand on the lectures, and include more recent progress. This article also includes an extensive set of references, as well as highlighting many open questions and problems. A set of "homework problems" is also included, one for each day of lecture.
THE EVOLUTION OF SEXUAL SIZE DIMORPHISM IN THE HOUSE FINCH. II. POPULATION DIVERGENCE IN RELATION TO LOCAL SELECTION

Abstract Recent colonization of ecologically distinct areas in North America by the house finch (Carpodacus mexicanus) was accompanied by strong population divergence in sexual size dimorphism. Here we examined whether this divergence was produced by population differences in local selection pressures acting on each sex. In a long-term study of recently established populations in Alabama, Michigan, and Montana, we examined three selection episodes for each sex: selection for pairing success, overwinter survival, and within-season fecundity. Populations varied in intensity of these selection episodes, the contribution of each episode to the net selection, and in the targets of selection. Direction and intensity of selection strongly differed between sexes, and different selection episodes often favored opposite changes in morphological traits. In each population, current net selection for sexual dimorphism was highly concordant with observed sexual dimorphism—in each population, selection for dimorphism was the strongest on the most dimorphic traits. Strong directional selection on sexually dimorphic traits, and similar intensities of selection in both sexes, suggest that in each of the recently established populations, both males and females are far from their local fitness optimum, and that sexual dimorphism has arisen from adaptive responses in both sexes. Population differences in patterns of selection on dimorphism, combined with both low levels of ontogenetic integration in heritable sexually dimorphic traits and sexual dimorphism in growth patterns, may account for the close correspondence between dimorphism in selection and observed dimorphism in morphology across house finch populations.

Infection and temporal arteritis: A PCR‐based study to detect pathogens in temporal artery biopsy specimens

The possibility of infectious triggers stimulating the development of inflammatory vascular diseases has generated much recent interest. This study uses PCR to detect the presence of Chlamydia pneumoniae, parvovirus B19 and all the human herpes viruses except HHV8 in temporal artery biopsy specimens. Samples from 37 temporal artery biopsies with histological evidence of arteritis and 66 samples from histologically negative temporal artery biopsies, all from different patients, were negative for C. pneumoniae, HSV, VZV, EBV, and HHV7 DNA. Two of the 37 histologically positive specimens were positive for HHV6, another two for CMV and a further two for parvovirus B19 DNA. Parvovirus B19 DNA was also detected in five histologically negative biopsies, one positive for HCMV DNA and a further one was positive for HHV6 DNA. There is no statistically significant difference to the presence of virus DNA in the two types of specimens (P = 0.538). This study does not support a role for C. pneumoniae, parvovirus B19 or human herpes viruses in the pathogenesis of temporal arteritis. J. Med. Virol. 80:501–505, 2008. © 2008 Wiley‐Liss, Inc.
The Psychological Autopsy and Determination of Child Suicides: A Survey of Medical Examiners

This study explored the decision-making processes of medical examiners in the determination of child suicide. Ninety-four medical examiners completed a survey regarding those factors considered when making a child suicide determination, sources of information used, and considerations in accident vs. suicide classifications. No significant differences between groups of respondents were observed. Well-known risk factors such as suicide notes were considered by virtually all participants, but other risk factors (e.g., substance abuse) were not consistently taken into consideration. Common sources of information included informant interviews and review of records. Results indicate that age and evidence of intent are critical considerations in this process. Implications in terms of misclassification and prevention efforts are discussed.
Mutational analysis of Greek patients with suspected hereditary neuropathy with liability to pressure palsies (HNPP): a 15‐year experience

There has been limited information from population studies regarding the overall frequency of the common 1.5‐Mb 17p11.2 deletion and even scarcer data regarding the overall frequency of PMP22 micromutations in patients with a clinical suspicion of hereditary neuropathy with liability to pressure palsies (HNPP). We have analysed 100 consecutive Greek patients referred for HNPP genetic testing over a 15‐year period to our Neurogenetics Unit in Athens, a reference centre for all regions of Greece. All patients were screened for the 1.5‐Mb deletion and a selected subgroup of deletion‐negative patients for PMP22 micromutations. Mutation‐positive and mutation‐negative patients were compared for various clinical parameters. In total, 54 mutation‐positive patients were identified. In index cases, the deletion frequency was 47.8%, and the PMP22 micromutation frequency was 2.2%. Within mutation‐positive patients, the common deletion represented 95.7% and PMP22 micromutations 4.3% of cases. Two previously reported PMP22 micromutations (c.364_365delCC and c.79‐2A>G) were detected. HNPP index cases had a 2.8–1 male‐to‐female ratio, similar to mutation‐negative patients. A typical phenotype (recurrent or isolated palsies) was present in 82.4% of symptomatic HNPP cases, significantly higher than mutation‐negative patients. Sensitivity of proposed electrophysiological diagnostic criteria for HNPP was calculated at 95.7% and specificity at 80.5%. In conclusion, the common HNPP deletion accounts for ∼50% and PMP22 micromutations for ∼2% of cases in a large consecutive cohort of patients with suspected HNPP. The mutational and phenotypic spectrum of HNPP is similar in the Greek population compared with other populations. Proposed electrophysiological diagnostic criteria perform satisfactorily in everyday clinical practice.
Epstein–Barr virus as a prognostic factor in de novo nodal diffuse large B-cell lymphoma

Although the International Prognostic Index (IPI) score is a valuable prognostic tool in diffuse large B-cell lymphoma (DLBCL), other risk-stratifying factors may be of value. The aim of this study was to define the prognostic value of EBV expression in de novo nodal DLBCL. Seventy-four cases were selected between January 2002 and December 2007. Clinical data were reviewed and tissue samples were evaluated for expression of CD20, CD10, bcl-6, MUM1, and EBV-encoded RNA (EBER). Of 74 evaluated cases, 53 cases (72%) were of non-germinal center-like subtype and 11 cases (15%) were positive for EBER. In a univariate analysis of the 57 patients who received chemotherapy, factors associated with survival were EBV status, performance status, LDH level, and IPI score. Using a multivariate analysis, a prognostic model was developed using IPI score and EBV status, which showed statistical significance. Our study supports EBV status as a powerful prognostic factor in de novo nodal DLBCL. Prospective studies should be carried to validate this hypothesis.
M5 Muscarinic Receptor Knockout Mice Show Reduced Morphine-Induced Locomotion but Increased Locomotion after Cholinergic Antagonism in the Ventral Tegmental Area

M5 muscarinic receptors are the only muscarinic receptor subtype expressed by mesencephalic dopamine neurons and provide an important excitatory input to mesolimbic and nigrostriatal dopamine systems. Here, we studied locomotion induced by systemic morphine (3, 10, and 30 mg/kg i.p.) in M5 knockout mice of the C57BL/6 (B6) and CD1 × 129SvJ background strains. M5 knockout mice of both strains showed reduced locomotion in response to 30 mg/kg morphine. B6 M5 knockout mice were less sensitive to naltrexone in either the antagonism of morphine-induced locomotion or in the reduction of locomotion by naltrexone alone. This suggests that M5 knockout mice are less sensitive to the effects of either exogenous or endogenous opiates on locomotion and that spontaneous locomotion in B6 mice is sustained by endogenous opiates. In B6 wild-type mice, ventral tegmental area (VTA) pretreatment with the muscarinic receptor antagonist atropine (3 μg bilateral), but not the nicotinic receptor antagonist mecamylamine (5 μg bilateral), reduced locomotion in response to 30 mg/kg morphine to a similar extent as systemic M5 knockout, suggesting that reduced morphine-induced locomotion in M5 knockout mice is due to the loss of M5 receptors on VTA dopamine neurons. In contrast, in M5 knockout mice, but not in wild-type mice, either intra-VTA atropine or mecamylamine alone increased locomotion by almost 3 times relative to saline and potentiated morphine-induced locomotion. Therefore, in M5 knockout mice, blockade of either VTA muscarinic or nicotinic receptors increased locomotion, suggesting that in the absence of VTA M5 receptors, VTA cholinergic inputs inhibit locomotion.
Harnessing Online Peer Education (HOPE): Integrating C-POL and social media to train peer leaders in HIV prevention

Abstract Novel methods, such as Internet-based interventions, are needed to combat the spread of HIV. While past initiatives have used the Internet to promote HIV prevention, the growing popularity, decreasing digital divide, and multi-functionality of social networking sites, such as Facebook, make this an ideal time to develop innovative ways to use online social networking sites to scale HIV prevention interventions among high-risk groups. The UCLA Harnessing Online Peer Education study is a longitudinal experimental study to evaluate the feasibility, acceptability, and preliminary effectiveness of using social media for peer-led HIV prevention, specifically among African American and Latino Men who have Sex with Men (MSM). No curriculum currently exists to train peer leaders in delivering culturally aware HIV prevention messages using social media. Training was created that adapted the Community Popular Opinion Leader (C-POL) model, for use on social networking sites. Peer leaders are recruited who represent the target population and have experience with both social media and community outreach. The curriculum contains the following elements: discussion and role playing exercises to integrate basic knowledge of HIV/AIDS, awareness of sociocultural HIV/AIDS issues in the age of technology, and communication methods for training peer leaders in effective, interactive social media-based HIV prevention. Ethical issues related to Facebook and health interventions are integrated throughout the sessions. Training outcomes have been developed for long-term assessment of retention and efficacy. This is the first C-POL curriculum that has been adapted for use on social networking websites. Although this curriculum has been used to target African-American and Latino MSM, it has been created to allow generalization to other high-risk groups.
Convergence of Numerical Solutions to Stochastic Age-Structured Population System

In this paper,we study the stochastic age-structured population system, which the fertility and mortality rate are influenced by population. In genaral, most of stochastic age-structured population system do not have explicit solutions, thus numerical approximation schemes are invaluable tools for exploring their properties. The main purpose of this paper is to develop a numerical scheme and show the convergence of numerical approximation solution to the ture solution.
Polymorphisms of glutathione S-transferase mu 1, theta 1, and pi 1 genes and prognosis in Hodgkin lymphoma

We examined the influence of the glutathione S-transferase mu 1 (GSTM1), theta 1 (GSTT1), and pi 1 (GSTP1) polymorphisms, which are involved in the metabolism of alkylating agents and anthracyclines, on the outcome of patients with Hodgkin lymphoma (HL) treated with conventional chemotherapy. Genomic DNA from 125 consecutive cases was analyzed by polymerase chain reaction and enzymatic digestion for polymorphism determination. The GSTM1 undeleted genotype was associated with more advanced tumor stage and worse disease-free survival. The GSTT1 undeleted genotype was associated with higher recurrence rate. In contrast, higher toxicity of chemotherapy was attributed to absence of the GSTT1 gene. Concerning overall survival, lower tumor stage (p = 0.006) and International Prognostic Score (p = 0.02), lower peripheral leukocyte count (p = 0.0003), higher serum albumin level (p = 0.08), and GSTT1 undeleted genotype (p = 0.04) were predictive of a better outcome of patients. In multivariate analysis comparing staging and GST polymorphism, only tumor stage and GSTT1 genotype remained in the model. Our results suggest that the GSTT1 polymorphism influences the outcome of Brazilian patients with HL. However, studies of toxicity, pharmacokinetics, and protein function may clarify whether carriers of the distinct genotypes should receive different doses of chemotherapeutic agents.
Quality of Life, Upper Extremity Function and the Effect of Lymphedema Treatment in Breast Cancer Related Lymphedema Patients

Objective To evaluate quality of life (QOL), upper extremity function and the effect of lymphedema treatment in patients with breast cancer related lymphedema. Method The basic data comprised medical records (detailing age, sex, dominant side, location of tumor, cancer stage, operation record, cancer treatment and limb circumferences) and questionnaires (lymphedema duration, satisfaction, self-massage). Further to this, we measured upper extremity function and QOL, administered the DASH (Disabilities of Arm Shoulder and Hand outcome measure) and used the EORTC (European Organization for Research and Treatment of Cancer)-QLQ-C30 and the EORTC-QLQ-Br23. Results of these were calculated as main outcome variables. Results The questionnaire responses and arm circumferences of 59 patients with breast cancer related lymphedema were analyzed. In the DASH questionnaire, it was found that the older the lymphedema patient was, the lower their upper extremity function. On the EORTC-QLQ, patients with metastasis had significantly lower scores in physical functioning and role functioning. In terms of upper extremity circumference, there was a significant upper extremity size reduction after lymphedema treatment. Conclusion There were several dissociations between some subscales of quality of life questionnaires and those of upper extremity functions. Upper extremity function was correlated with the age of breast cancer patients and QOL was influenced by M-stage. Lymphedema treatment was found to be effective in reducing edema in patients with breast cancer related lymphedema.
Gradual evolution of male genitalia in a sibling species complex of millipedes (Diplopoda:Spirobolida:Rhinocricidae:Anadenobolus)

Jamaican millipedes in the Anadenobolus species complex provide an unusual case study of arthropods having undergone speciation in the absence of conspicuous divergence of male genitalia. Using landmark-based morphometrics, we examined shape deformation of the male anterior copulatory device in three genetically divergent yet morphologically cryptic species. A multivariate analysis of variance and relative warp analysis of nonuniform components show that although male genitalic shape is statistically different among species, many specimens are 'misplaced' in morphological space, perhaps consistent with a condition analogous to incomplete lineage sorting. A simulation of neutral nuclear gene coalescence suggests that such incomplete sorting is expected, given the depth of mtDNA divergences observed across species. The pronounced contrast between deep molecular v. incomplete genitalic divergence is at odds with the paradigm of selection-driven rapid change in male copulatory structure during arthropod speciation. Alternatively, we suggest that male genitalic divergence is evolving neutrally or in concert with other components of the genome (pleiotropy). Although we recognise the empirical validity of rapid genitalic divergence via sexual selection or sexual conflict, such models must be empirically tested using multiple lines of evidence. Accepting the rapid and divergent hypothesis without such multiple evidence scrutiny may result in a gross underestimation of evolutionary diversity and, subsequently, the misinterpretation of processes shaping genitalic change.
Association of dental and skeletal fluorosis with calcium intake and serum vitamin D concentration in adolescents from a region endemic for fluorosis

Context: Fluorosis is controlled by the duration of fluoride exposure and calcium and Vitamin D nutrition status. Aim: To examine (a) prevalence of dental and skeletal fluorosis in adolescents from upper, middle, and lower socioeconomic strata (SES) and (b) association of fluorosis with calcium intake and Vitamin D status. Settings and Design: A cross-sectional study conducted in 10–13.9 years apparently healthy adolescents (n = 90), from different SES of Patan (Gujarat, India). Materials and Methods: Dental fluorosis was graded as mild, moderate, and severe. Radiographs of the right hand and wrist were examined and graded. Serum 25 hydroxyvitamin D3 (25OHD) and parathyroid hormone concentrations were measured. Diet was recorded (24 h recall) and calcium intake was computed (C-diet V-2.1, 2013, Xenios Technologies Pvt. Ltd). Statistical Analysis: Generalized linear model was used to analyze relationships between fluorosis, SES, serum 25OHD concentration, and calcium intake. Results: Fluorosis was predominant in lower SES (17% had both dental and radiological features whereas 73% had dental fluorosis); no skeletal deformities were observed. Mean 25OHD concentrations and dietary calcium were 26.3 ± 4.9, 23.4 ± 4.7, and 18.6 ± 4 ng/ml and 441.2 ± 227.6, 484.3 ± 160.9, and 749.2 ± 245.4 mg/day, respectively, for lower, middle, and upper SES (P < 0.05). Fluorosis and SES showed a significant association (exponential β = 2.5, P = 0.01) as compared to upper SES, middle SES adolescents were at 1.3 times while lower SES adolescents were at 2.5 times higher risk. Serum 25OHD concentrations (P = 0.937) and dietary calcium intake (P = 0.825) did not show a significant association with fluorosis. Conclusion: Fluorosis was more common in lower SES adolescents, probably due to the lack of access to bottled water. Relatively adequate calcium intake and serum 25OHD concentrations may have increased the efficiency of dietary calcium absorption, thus preventing severe fluorosis.
