Some Variables in Audio Spectrometry

Measurements of the long‐time average spectrum of speech are reported with the purpose of pointing out the roles of several variables. Three different sampling times of three different types of speech material are analyzed with several band‐width intervals. The speech of five young men and five young women contributes to the averaged results.No significant differences are found among the three types of speech material nor among the three different sampling times of 30, 60, and 90 seconds. Octave, half‐octave and equal‐mel intervals appear to yield the same results. The only important difference between male and female speech appears in the octave 75–150 cps. The shape of the long time spectrum remains fairly constant from person to person while the over‐all level contributes most to interpersonal variability. A discussion of the meaning of “over‐all level” in this and previous reports is given.A relatively simple system for obtaining these measurements is described.
A Task-Scheduling Approach for Efficient Sparse Symmetric Matrix-Vector Multiplication on a GPU

In this paper, a task-scheduling approach to efficiently calculating sparse symmetric matrix-vector products and designed to run on graphics processing units (GPUs) is presented. The main premise is that, for many sparse symmetric matrices occurring in common applications, it is possible to obtain significant reductions in memory usage and improvements in performance when the matrix is prepared in certain ways prior to computation. The preprocessing proposed in this paper employs task scheduling to overcome the difficulties that have suppressed the development of methods taking advantage of the symmetry of sparse matrices. The performance of the proposed task-scheduling method is verified using a Kepler (Tesla K40c) graphics accelerator, and is compared to the performance of cuSPARSE library functions on a GPU and to functions from the Intel MKL on central processing units (CPUs) executed in the parallel mode. The obtained results indicate that the proposed approach for sparse symmetric matrix-vector prod.
On the Uniqueness and Perturbation to the Best Rank-One Approximation of a Tensor

The uniqueness of the best rank-one approximation of a tensor under the Frobenius norm is a basic and important studying subject in the tensor theory. By introducing the quasi-singular value of a tensor, we present a new sufficient condition under which the best rank-one approximation of a nonzero tensor $\underline{X}\in\mathbb{R}^{d_{1}\times d_{2}\times d_{3}}$ is unique and obtain that the set consisting of all tensors satisfying the sufficient condition is an open and dense set in $\mathbb{R}^{d_{1}\times d_{2}\times d_{3}}$. In addition, we present a necessary and sufficient condition under which the best rank-one approximation of the sum tensor $\underline{\tilde X}=\underline{X} + {\underline E}$ under some assumption on the tensor $\underline{\tilde X}\in\mathbb{R}^{d_{1}\times d_{2}\times d_{3}}$ is equal to the best rank-one approximation of ${\underline X}$. Meanwhile, a numerical algorithm is proposed for computing the quasi-singular value of a tensor. Finally, several testing examples are pr.
Women's Experiences of Fetal Movements before the Confirmation of Fetal Death--Contractions Misinterpreted as Fetal Movement.

BACKGROUND Decreased fetal movement often precedes a stillbirth. The objective of this study was to describe women's experiences of fetal movement before the confirmation of fetal death. METHODS Data were collected through a Web-based questionnaire. Women with stillbirths after 28 gestational weeks were self-recruited. Content analysis was used to analyze the answers to one open question. The statements from mothers of a stillborn, born during gestational weeks 28 to 36 were compared with those of a stillborn at term. RESULTS The women's 215 answers were divided into three categories: decreased, weak, and no fetal movement at all; 154 (72%) of the descriptions were divided into three subcategories: decreased and weak movement (106; 49%), no movement at all (35; 16%), and contraction interpreted as movement (13; 6%). The category fetal movement as normal includes 39 (18%) of the descriptions. The third category, extremely vigorous fetal activity followed by no movement at all, includes 22 (10%) of the descriptions. Eight (15%) of the women with stillbirths in gestational weeks 28 to 36 interpreted contractions as fetal movement as compared to 5 (5%) of the women with stillbirths at term. DISCUSSION Uterine contractions can be interpreted as fetal movement. A single episode of extremely vigorous fetal activity can precede fetal death. The majority of the women experienced decreased, weaker, or no fetal movement at all 2 days before fetal death was diagnosed. Mothers should be educated to promptly report changes in fetal movement to their health care providers. Using fetal movement information to evaluate possible fetal distress may lead to reductions in stillbirths.
On Artifacts in Limited Data Spherical Radon Transform: Flat Observation Surfaces

In this paper, we characterize the strength of the reconstructed singularities and artifacts in a reconstruction formula for limited data spherical Radon transform. Namely, we assume that the data is available only on a closed subset $\Gamma$ of a hyperplane in $\mathbb{R}^n$ ($n=2,3$). We consider a reconstruction formula studied in some previous works, under the assumption that the data is only smoothed out to a finite order $k$ near the boundary. For the problem in two-dimensional space when $\Gamma$ is a line segment, the artifacts are generated by rotating a boundary singularity along a circle centered at an end point of $\Gamma$. We show that the artifacts are $k$ orders smoother than the original singularity. For the problem in three-dimensional space when $\Gamma$ is a rectangle, the artifacts are generated by rotating a boundary singularity around either a vertex or an edge of $\Gamma$. The artifacts obtained by a rotation around a vertex are $2k$ orders smoother than the original singularity. Me.
α‐Thalassaemia in the population of Cyprus

We have determined the α‐thalassaemia (α‐thal) determinants in 78 patients with Hb H disease from Cyprus; 25 were Turkish Cypriots and 53 were Greek Cypriots. Four deletional and three non‐deletional α‐thal alleles were present; the ‐α(3.7 kb) α‐thal‐2 and the —MED‐1α‐thal‐1 were most frequently seen; —MED‐II and ‐(α)20.5 deletions occurred at considerably lower frequencies. About 15% of all chromosomes carried a non‐deletional α‐thal‐2 allele; of these the 5 nucleotide (nt) deletion at the first intervening sequence (IVS‐I) donor splice site was present in ˜ 8% of all chromosomes. Two types of polyadenylation signal (poly A) mutations were observed. No striking frequency differences were seen between Greek and Turkish Cypriot patients. Combinations of the various types of α‐thal resulted in eight different forms of Hb H disease. The phenotypes were comparable except for great variations in the level of Hb H which was highest (average ˜ 22%) in the 12 patients with the α5ntα/—MED‐I combination. One patient with the same form of Hb H disease but with an additional β‐thal (IVS‐I‐110, G → A) heterozygosity had a most severe microcytosis and hypochromia with < 1% Hb H. Variations in the level of Hb H might correlate with the severity of the disease, although this was not evident from the haematological data.
Physical Activity and Sedentary Behaviour as Predictors of Adolescent Health in Rural and Urban Environments in Poland

Physical Activity and Sedentary Behaviour as Predictors of Adolescent Health in Rural and Urban Environments in Poland While numerous studies have examined correlates of physical activity, less attention has been given to identifying the rural/urban differences in the strength of the relationship between physical activity and health. The main objective of the current study was to analyze relationships between physical activity, sedentary behavior, and the health of rural and urban adolescents. Cross-sectional data on physical activity (Moderate-to-Vigorous Physical Activity, MVPA), sedentary behavior (watching TV and using a computer), self-rated general health, and mental health (General Health Questionnaire, GHQ-12) was assessed through a questionnaire in the sample of 600 Polish adolescents aged 13 years. Pearson χ2, t-Student tests and hierarchical regression analyses were used to compare differences by place of residence. No rural/urban differences in physical activity levels and self-rated health were found. Rural boys spent more time watching TV and urban adolescent males spent more time using a computer. Urban girls were more affected by stress than rural. Physical activity was an important predictor of self-assessed health (8% of variance) and mental health (4% of variance) of adolescents living in rural areas. The results show that physical activity level is an important predictor of rural adolescents’ health and particular attention must be paid to promoting physical activities in rural environments.
Stochastic Approximation Based Consensus Dynamics over Markovian Networks

This paper considers consensus problems with random networks. A key object of our analysis is a sequence of stochastic matrices which involve Markovian switches and decreasing step sizes. We establish ergodicity of the backward products of these stochastic matrices. The basic technique is to consider the second moment dynamics of an associated Markovian jump linear system and exploit its two-scale interaction property resulting from the decreasing step sizes. The mean square convergence rate of the backward products is also obtained. The ergodicity results are used to prove mean square consensus of stochastic approximation algorithms where agents collect noisy information. The approach is further applied to a token scheduled averaging model.
A General Integral Quadratic Constraints Theorem with Applications to a Class of Sampled-Data Systems

In the framework of integral quadratic constraints a more general stability theorem is derived by relaxing the assumptions on the uncertainty. In contrast to existing results, input-output relations are only required to hold on a subspace of the full signal space. This result is employed to incorporate uncertainties exhibiting sampling behavior into the framework of integral quadratic constraints. The arising infinite dimensional stability test is exactly reduced to a finite dimensional linear matrix inequality. Advantages of this approach are illustrated for the specific case of an interconnection including a pulse-width modulator.
Sharp Entrywise Perturbation Bounds for Markov Chains

For many Markov chains of practical interest, the invariant distribution is extremely sensitive to perturbations of some entries of the transition matrix, but insensitive to others; we give an example of such a chain, motivated by a problem in computational statistical physics. We have derived perturbation bounds on the relative error of the invariant distribution that reveal these variations in sensitivity. Our bounds are sharp, we do not impose any structural assumptions on the transition matrix or on the perturbation, and computing the bounds has the same complexity as computing the invariant distribution or computing other bounds in the literature. Moreover, our bounds have a simple interpretation in terms of hitting times, which can be used to draw intuitive but rigorous conclusions about the sensitivity of a chain to various types of perturbations.
Stability of Antiphase Oscillations in a Network of Inhibitory Neurons

We investigate antiphase, oscillatory behavior in a model network of two mutually coupled, identical neurons with inhibitory synapses. Each neuron is described as a relaxation oscillator, and the synapses are modeled in such a way that the synaptic activation occurs rapidly, but its inactivation proceeds with a speed comparable to the slow process of the intrinsic oscillator. Using fast/slow analysis, we construct a two-dimensional map, reducing the problem of proving the existence of a stable antiphase solution of the model into proving the existence of a stable fixed point of the map. Through a detailed analysis of this map, we derive precise conditions on the network parameters---particularly, the decay rate of the synapses and duty cycle of the oscillator---for when there exists a stable antiphase solution.
Social anxiety, submissiveness, and shame in men and women: a moderated mediation analysis.

OBJECTIVES Research suggests a positive relationship between social anxiety and shame; however, few studies have examined this relationship or potential mechanisms. Common behaviours of persons with social anxiety disorder (SAD), such as submissive behaviours, may be more consistent with societal expectations of women than men and therefore more likely to be associated with shame in socially anxious men than women. We examined the hypothesis that submissive behaviours would mediate the relationship between social anxiety and shame in men, but not in women, with SAD. DESIGN Moderated mediation was examined in a cross-sectional dataset. Gender was modeled to moderate the paths from social anxiety to submissive behaviours and from submissive behaviours to shame. We also examined an alternative model of the relationships among these variables and the potential contributory role of depression. METHODS Men (n = 48) and women (n = 40) with SAD completed the Social Interaction Anxiety Scale, Submissive Behaviour Scale, Internalized Shame Scale, and Beck Depression Inventory. RESULTS Analyses supported the hypothesized model. The relationship between submissive behaviours and shame was greater in men than women with SAD; the relationship between social anxiety and submissive behaviours was not. Controlling for depression, moderation remained evident although diminished. Results for the comparison model did not support gender moderation. CONCLUSIONS Submissive behaviours mediated the relationship between social anxiety and shame in men, but not women, with SAD. These findings provide preliminary evidence for a model of shame in SAD and may help to further elucidate specific features of SAD that differ between men and women. PRACTITIONER POINTS Although researchers have argued that the display of submissive behaviours might allow the socially anxious individual to limit or prevent attacks on the self, our results suggest that there are greater costs, with regard to feelings of shame, associated with such behaviours for men. In men with SAD, the greater shame associated with submissive behaviours can be understood when considering that socially anxious individuals appear to be particularly concerned with concealing aspects of the self believed to violate perceived societal norms and that traditional masculine gender roles revolve around the theme of dominance. Because the study was conducted in individuals with SAD, it is possible that the restricted range of social anxiety severity may have precluded the observation of gender differences in the relationship between social anxiety and submissive behaviour. Measures were administered in a cross-sectional design, which limits potential inferences of causality.
The Prevalence of Attempted Suicides in Proportion of Referrals to Emergency Departments in Karaj, Iran

Introduction: The World Health Organization (WHO) has recognized suicidal behaviors as a serious public health problem in developed and developing countries. To increase the knowledge about suicidal behaviors, WHO has carried out the Multisite Intervention Study on Suicidal Behaviors (SUPRE-MISS) across eight countries. This paper presents data from the site in Karaj, Islamic Republic of Iran. Method: Karaj, with an urban population of 941,000, was selected as a catchment area. For the duration of the study all emergency departments (EDs) in the city were covered for 24 hours to identify suicide attempters who were presented the SUPRE-MISS questionnaire, consisting of comprehensive personal, family, social, somatic, and psychiatric variables. Results: During 10 months, 945 suicide attempters (the mean of referrals per month was 98) were referred to EDs (0.12 percent of the urban population in one year). Age, education, marriage, employment and occupational status, and the method of the suicide attempt had a significant correlation with the gender of the attempters (p < .001). Overall, 0.2 percent of the particpants died due to the suicide attempt. At the time of discharge, only 5.5 percent of the particpants were referred to psychiatric or consultation services. Conclusions: The comparison of the rate of suicidal behaviors generated from community and EDs studies gives an indication of the mental health services needed for particpants at risk of suicide.
Guided parent‐delivered cognitive behaviour therapy for children with anxiety disorders: Outcomes at 3‐ to 5‐year follow‐up

OBJECTIVES Brief guided parent-delivered cognitive behaviour therapy (CBT) has been developed to meet the demand for non-intensive interventions for children with anxiety disorders, and initial trials have shown it to be effective for children with a range of anxiety disorders. This study examined outcomes 3-5 years post-treatment. DESIGN A long-term follow-up (LTFU) cohort study. METHODS Families who (1) completed at least 50% of allocated treatment sessions of guided parent-delivered CBT for childhood anxiety as part of a randomized control trial (RCT), (2) provided consent to be recontacted, (3) had not received further mental health interventions, and (4) were contactable were invited to take part. Fifty-seven families (29% of the original sample) completed structured diagnostic interviews on average 50 months after treatment (39-61 months). RESULTS At LTFU, 79% of the assessed children who had received the treatment no longer met criteria for their primary diagnosis, 63% did not meet criteria for any anxiety disorder, and 61% did not meet criteria for any DSM-IV disorder. Treatment gains were mostly maintained (60%), and some children went on to recover during the follow-up period without additional input from mental health services (19%). Few young people had relapsed since their last assessment (12%). Mean scores on standardized symptom questionnaires were within the normal range. CONCLUSIONS Children who recovered from anxiety disorders following brief guided parent-delivered CBT typically maintained good outcomes and few relapsed. These findings suggest that this is a viable first-line, low-intensity treatment approach. This study only included a small subsample of those in the original RCT (29%), and more information is required about those who dropped out of treatment and those who required further intervention immediately after treatment. PRACTITIONER POINTS Treatment gains from brief guided parent-delivered cognitive behaviour therapy for children with anxiety are maintained for most children 3-5 years later. The majority of children who completed at least 50% of the intervention required no further mental health intervention in that time. Some children make continued improvement after completing the intervention. Data are based on a sample of families from southern England where the primary caregiving parent was free of mental health difficulties. Further research is needed to explore the mental health needs of those who do not benefit from this intervention.
Energy Consumption of Taekwondo Practitioners due to a Thigh Muscle Extracted by CT Scan

Despite the suzerain of Korea Taekwondo physical activity and a corresponding lack of basic research on energy consumption and the status of this research is urgent. In this study, the sensor (SenseWear (R) PRO2 Armband), using physical activity were obtained in Taekwondo, and body composition data were obtained by Inbody 520, We were thigh scan using CT scanner and thigh muscle area by CT scan data were acquired. Result of analysis, average thigh muscle area of experimenter 8 people was 132.79 , Of 20 cm above the patella thigh was a 178.79 . Thigh circumference and muscle area showed that the correlation. The average energy consumption per minute was 6.94 calories, and thigh muscle area and average energy consumption per minute also showed that correlation.
POC14 Treatment-resistant hyponatraemia

A 37-year-old female presented with fluctuating focal neurological symptoms, signs and seizures. Initially the aetiology was suspected to be functional but review by the attending neurologist confirmed the diagnosis of cerebral venous sinus thrombosis. Magnetic Resonance imaging showed extensive left cerebral hemisphere infarction. Three weeks after initial presentation she became progressively drowsy coinciding with a decreasing serum sodium level. Examination revealed a dense right hemiparesis (Medical Research Council grading 0/5). She was clinically euvolaemic and blood tests were as follows; serum osmolality 276 mOsmol/kg, urine osmolality 896 mOsmol/kg, urine sodium 141 mmol/l and serum sodium 122 mmol/l. A diagnosis of syndrome of inappropriate antidiuretic hormone (SIADH) was made. Despite fluid restriction and demeclocycline the serum sodium continued to decline to 114 mmol/l. The patient then developed acute renal dysfunction and hypertonic saline was administered. The patient was commenced on the vasopressin antagonist tolvaptan. The serum sodium improved and further pharmacological therapy was not required. The timing, clinical and biochemical picture were convincing for SIADH, however the response to standard initial treatment was more that of cerebral salt wasting syndrome (CSWS). Diagnostic uncertainty between these two conditions remains a challenging situation in both neurology and neurosurgery.
Qualitative and Numerical Analysis of a Spectral Problem with Perimeter Constraint

We consider the problem of optimizing the $k{\text{th}}$ eigenvalue of the Dirichlet Laplace operator under perimeter constraint. We provide a new method based on a $\Gamma$-convergence result for approximating the corresponding optimal shapes. We also give new optimality conditions in the case of multiple eigenvalues. We deduce from previous conditions the fact that optimal shapes never contain flat parts in their boundaries.
Variational Analysis and Regularity of the Minimum Time Function for Differential Inclusions

We study the time optimal control problem for differential inclusions with a general closed target. We first give the representation of the proximal horizontal subgradients of the minimum time function $\mathcal{T}$ and then, together with the representation of the proximal subgradients, we obtain some relationships between the normal cones to the sublevel of $\mathcal{T}$ and the normal cones to its epigraph. The relationships allow us to get the propagation of the proximal subdifferential as well as of the proximal horizontal subdifferential of $\mathcal{T}$ along optimal trajectories. Finally, we show, under suitable assumptions, that the epigraph of $\mathcal{T}$ is $\varphi$-convex near the target. This is the first nonlinear $\varphi$-convexity result valid in any dimension.
