Perceiving emotions from bodily expressions and multisensory integration of emotion cues in schizophrenia

Most studies investigating emotion recognition in schizophrenia have focused on facial expressions and neglected bodily and vocal expressions. Furthermore, little is known about affective multisensory integration in schizophrenia. In the first experiment, the authors investigated recognition of static, face-blurred, whole-body expressions (instrumental, angry, fearful, and sad) with a two-alternative, forced-choice, simultaneous matching task in a sample of schizophrenia patients, nonschizophrenic psychotic patients, and matched controls. In the second experiment, dynamic, face-blurred, whole-body expressions (fearful and happy) were presented simultaneously with either congruent or incongruent human or animal vocalizations to schizophrenia patients and controls. Participants were instructed to categorize the emotion expressed by the body and to ignore the auditory information. The results of Experiment 1 show an emotion recognition impairment in the schizophrenia group and to a lesser extent in the nonschizophrenic psychosis group, and this for all four expressions. The findings of Experiment 2 show that schizophrenia patients are more influenced by the auditory information than controls, but only when the auditory information consists of human vocalizations. This shows that schizophrenia patients are impaired in recognizing whole-body expressions, and they show abnormal affective multisensory integration of bimodal stimuli originating from the same source.
A New Connectionist-SCHMM Approach to Speech Recognition over Telephone Lines

This talk compares a newly proposed hybrid connectionist-SCHMM approach [6] with other hybrid approaches. In the new approach, a multilayer perceptron (MLP) replaces the conventional codebooks of semi-continuous HMMs. The MLP is therefore trained on so-called basic elements (phones and phone parts) in such a way that the outputs of the network estimate the a posteriori probabilities of these elements, given a context of input vectors. These a posteriori estimates are converted into scaled likelihoods, which are then used as observation probabilities in the framework of classical SCHMMs. The remaining parameters of the SCHMMs are trained with the well-known Baum-Welch algorithm using the estimated likelihoods of the MLP. For a single feature, this approach compared favorably with other hybrid and classical approaches on an isolated German digit recognition task over telephone lines. It exhibited the highest recognition rate of all systems, followed by an approach using LVQ3 optimization of the codebooks. In the case of multiple features, additional design considerations had to be observed for the connectionist-SCHMM system in order to improve the performance over classic HMM approaches.
Design and Analysis of Hybrid Flow Control for Hierarchical Ring Network-on-Chip

A cost-efficient network-on-chip is needed in a scalable many-core systems. Recent multicore processors have leveraged a ring topology and hierarchical ring can increase scalability but presents different challenges, including higher hop count and global ring bottleneck. In this work, we describe a hierarchical ring topology that we refer to as a transportation-network-inspired network-on-chip (tNoC) that leverages principles from transportation network systems. In particular, we propose a novel hybridflow control for hierarchical ring topology to scale the topology efficiently. The flow control is hybrid in that the channels are allocated on flit granularity while the buffers are allocated on packet granularity. The hybrid flow control enables a simplified router microarchitecture (to minimize per-hop latency) as router input buffers are minimized and buffers are pushed to the edges, either at the output ports or at the hub routers that interconnect the local rings to the global ring-while still supporting virtual channels to avoid protocol deadlock. We describe a packet-quota-system (PQS) and a separate credit network that provide congestion management, support prioritized arbitration in the network, and provide support for multiflit packets. We also provide alternative designs for the credit network and PQS architectures. A detailed evaluation of a 64-core CMP shows that the tNoC improves performance by up to 21 percent compared with a baseline, buffered hierarchical ring topology while reducing NoC energy by 51 percent.
Calcifying fibrous tumor of stomach

Rationale Calcifying fibrous tumor (CFT) is a rare benign soft tissue mesenchymal neoplasm. Although the gastrointestinal (GI) tract is the most common predilection site of CFT, the clinicians, even including pathologist, generally consider it as GI stromal tumor (GIST) or other submucosal tumors such as schwannoma and leiomyoma. Patient concerns A 55-year-old man presented with complaints of epigastric discomfort and abdominal distention for more than 1 year. Diagnoses On the basis of endoscopic and computed tomography examination, preliminary diagnosis was GIST. Interventions Endoscopic submucosal dissection (ESD) surgery was performed to remove the gastric mass. Outcomes The histopathological examination revealed a gastric CFT. Lessons We present a case of gastric CFT, which was misdiagnosed as GIST based on endoscopic and radiologic findings.
Factors affecting the in vitro action of cumulus cells on the maturing mouse oocytes

The removal of cumulus cells (CCs) from oocytes at the germinal vesicle (GV) stage still represents a major limitation in such embryo techniques as GV transfer, somatic cell haploidization, and oocyte cryopreservation. However, no efficient in vitro maturation (IVM) system for CC‐denuded oocytes (DOs) has been established in mammalian species. Although follicular cells are considered to play an important role in oocyte maturation, the specific role and mechanisms of action of different cell types are poorly understood. Reports on whether junctional association between CCs and the oocyte is essential for the beneficial effect of CC co‐culture on oocyte maturation are in conflict. Our objective was to try to address these issues using the mouse oocyte model. The results indicated that while co‐culture with the CC monolayer could only partially restore the developmental potential of DOs without corona cells, it restored the competence of corona‐enclosed DOs completely. Culture in medium conditioned with CC monolayer also promoted maturation of DOs. However, co‐culture with the monolayer of mural granulosa cells had no effect. The efficiency of CC co‐culture was affected by various factors such as density and age of the CCs, the presence of gonadotropin in the maturation medium and the duration for in vivo (IVO) gonadotropin priming. It is concluded that mouse CCs produce a diffusible factor(s) that support DO maturation in a CC‐oocyte junctional communication dependent manner. The data will contribute to our understanding the mechanisms by which CCs promote oocyte maturation and to the establishment of an efficient DO IVM system. Mol. Reprod.

Concomitant Disorders in School-Age Children Who Stutter.

PURPOSE The purposes of this survey study were to (a) determine the number of children who stutter with verified concomitant phonological and language disorders, (b) determine the number of children who stutter with suspected concomitant phonological and language disorders, and (c) determine the type of treatment clinicians use with these children. METHOD A systematic sampling plan was used to obtain survey responses from 241 American Speech-Language-Hearing Association (ASHA)-certified, school-based speech-language pathologists from 10 states that were considered to have similar state verification criteria for fluency, articulation/phonology, and language disorders. Respondents were asked to provide information concerning verified and suspected concomitant disorders in children who stutter. They also were asked to select one of four types of intervention approaches suggested by Bernstein Ratner (1995) in treating concomitant disorders in stuttering (i.e., blended, cyclic, sequential, and concurrent). RESULTS The speech-language pathologists reported on 467 children who stuttered. Of that total, 262 (56%) children had a fluency disorder only and 205 (44%) had a verified concomitant phonological and/or language disorder. A subgroup of children with verified fluency-only disorders were suspected of having a concomitant disorder. When treating a fluency and a concomitant phonological and/or language disorder, the majority of clinicians used a blended approach. CLINICAL IMPLICATIONS Using similar state verification guidelines, this survey showed that a large percentage of preschool through high school students possessed a verified fluency disorder and a phonological and/or language disorder. Thus, clinicians need to be aware of the strong possibility that school-age children who stutter might have a phonological disorder and/or a language disorder. Additionally, because the majority of respondents used a blended treatment approach when treating children with a fluency and a verified concomitant phonological and/or language disorder, it appears that many school-based clinicians believe it is best to address both problems simultaneously.
Teaching Mainstream American English

Because many Black students speak Ebonics, the problem of teaching Mainstream American English (MAE) to them has become somewhat controversial. Some scholars recommend utilizing foreign language teaching methods which recognize the need for contrasting the systematic phonological and grammatical features of Ebonics with those of MAE. Traditional "on-the-spot" corrections have been ineffective. The purposes of this article are (a) to point out some similarities and differences in teaching MAE to speakers of Ebonics and foreign languages; (b) to point out some pedagogical problems in adapting second language teaching techniques for teaching MAE to speakers of Ebonics; and (c) to illustrate the similarities of training teachers to teach MAE to speakers of Ebonics and to speakers of foreign languages. The United States of America is made up of various groups. That is, the United States (referring to geographic divisions), and the peoples who inhabit its geographical divisions (refer-
Mice without the Regulator Gene Rsc1A1 Exhibit Increased Na+-d-Glucose Cotransport in Small Intestine and Develop Obesity

ABSTRACT The product of the intronless single copy gene RSC1A1, named RS1, is an intracellular 617-amino-acid protein that is involved in the regulation of the Na+-d-glucose cotransporter SGLT1. We generated and characterized RS1 knockout (RS1− / −) mice. In the small intestines of RS1 − / − mice, the SGLT1 protein was up-regulated sevenfold compared to that of wild-type mice but was not changed in the kidneys. The up-regulation of SGLT1 was posttranscriptional. Small intestinal d-glucose uptake measured in jointly perfused small bowel and liver was increased twofold compared to that of the wild-type, with increased peak concentrations of d-glucose in the portal vein. At birth, the weights of RS1 − / − and wild-type mice were similar. At the age of 3 months, male RS1 − / − mice had 5% higher weights and 15% higher food intakes, whereas their energy expenditures and serum leptin concentrations were similar to those of wild-type mice. At the age of 5 months, male and female RS1 − / − mice were obese, with 30% increased body weight, 80% increased total fat, and 30% increased serum cholesterol. At this age, serum leptin was increased, whereas food intake was the same as for wild-type mice. The data suggest that the removal of RS1 leads to leptin-independent up-regulation of food intake, which causes obesity.
Students' and Teachers' Perceptions of Adolescents' Problems and Coping Strategies

In an investigation of the problems and coping strategies of Australian high school students, comparisons were made between the responses of 1664 students enrolled in Years 8 to 12 in 1988,1620 students enrolled in the same year levels in 1993, and 178 high school teachers in 1993. The subjects completed the High School Stressors Scale (Burnett & Fanshawe, 1997) and the Adolescent Coping Strategies Scale (Burnett & Fanshawe, 1996). Data analyses using MANOVAs, ANOVAs, and t-tests revealed close similarities between the responses of the 1993 students and those of the 1988 students, but a considerable amount of incongruence between the responses of the students and those of the teachers. In particular, the teachers generally seemed to regard their students' problems as being more serious than was acknowledged by the students, and the teachers generally seemed to project a less positive view of adolescents' coping strategies than did the students. These discrepancies are discussed in terms of the different orientations that students and teachers bring to the student-teacher relationship. It is suggested that teachers and counsellors need to take cognisance of the differences between adolescents' perspectives and their own if they are going to be effective in assisting students to develop positive coping strategies and in creating more positive learning environments.
Complete loss of F-waves during cataplectic attacks in patients with narcolepsy

Cataplexy is one of the hallmark symptoms of patients diagnosed with narcolepsy type 1 (N1 = narcolepsy with cataplexy). Our pathophysiologic understanding of cataplexy has been based on the hypothesis that the loss of muscle tone characteristic for cataplectic attacks (CA) is identical to muscle atonia in REM sleep.1 However, this hypothesis has not been proved in humans since cataplexy can hardly be provoked experimentally. Recently, F-waves have been shown to be a valuable marker for spinal inhibition in REM sleep.2 We present F-wave recordings in 3 patients with N1 before, during, and after a CA (figure) to test whether the level of spinal excitability in cataplexy equals that in REM sleep.
Will Web Surveys Ever Become Part of Mainstream Research?

Leece et al used systematic sampling to assign one half of a list of orthopedic surgeons to a Web survey and the other half to a mail survey [1]. They observed that the Web survey produced a significantly lower response rate than the mail survey, and cautioned, “Researchers should not assume that the widespread availability and potential ease of Internet-based surveys will translate into higher response rates. ” In contrast, Ritter et al, who recruited participants from the Internet and randomly assigned them either to a mail survey or to a Web survey, observed different results [2]. They found that participation was at least as good as if not better among the Web survey group than among those receiving questionnaires by mail. In addition the investigators found that the responses to 16 health-related questions did not differ significantly between the two study groups.
Serotonin function, personality-trait variations, and childhood abuse in women with bulimia-spectrum eating disorders.

BACKGROUND Across populations, findings associate impulsivity, behavioral disinhibition, or hostility with reduced central serotonin (5-hydroxytryptamine: 5-HT) activity and increased likelihood of childhood abuse. Inconsistently, findings associate compulsivity, behavioral inhibition, or anxiousness with elevated 5-HT neurotransmission. We explored relationships among measures of 5-HT system functioning, behavioral inhibition/disinhibition, and childhood abuse in women with bulimia-spectrum eating syndromes. METHOD In 73 bulimic (body mass index [kg/m2] under 30, binge eating at least once weekly) and 50 normal-eater control women, we obtained indices of platelet paroxetine binding and 5-HT agonist (m-CPP)-stimulated neuroendocrine responses. Cluster analysis was used to classify the bulimic women according to 5-HT "profiles. " Resulting groups were then compared on symptom and trait measures. RESULTS Measures of paroxetine-binding density (Bmax) and affinity (Kd) contributed significantly (p < .001 and p < .02, respectively) to a classification of bulimic women into groups with "low density/high affinity" (N = 52) or "high density/low affinity" (N = 21) binding. The 5-HT based classification did not predict eating-symptom severity. However, the "high density" pattern was associated with increased perfectionism and compulsivity, reduced risk of childhood sexual abuse, and (to some extent) reduced probability of borderline personality disorder. DISCUSSION In women with bulimic syndromes, serotonergic factors, personality-trait variations, and developmental typologies converge in principled fashion. Our findings corroborate (with neurobiological evidence) the concept of underregulated and overregulated subtypes within the bulimic population.
A Combination Technique of Multi-wavelets and Interpolation for Resolution Enhancement of Digital Images

— This paper explains the effect of various multi-wavelet interpolation methods on digital images to enhance the resolution of the images. A high resolution image is a major challenge for any image processing application, especially in defense and medical scenario. Here resolution enhancement technique is done in wavelet domain using multi-wavelets and interpolation methods. Visual perception of an image has to be improved by various enhancement techniques since the hardware image acquisition methods drops to a limit. Some spectral and spatial problems such as motion blur, pixilation and poor perception may still prevail in digital images which requires rectification before processing further. The Super Resolution images are generated by applying enhancement techniques on a set of noisy and blurred low resolution images . In this paper, some of the resolution enhancement techniques such as Discrete Wavelet Transform, Stationery Wavelet Transform and a combination of DWT and SWT with various interpolation techniques are experimented. The DWT-SWT with Bilinear interpolation method illustrates the improvement in the resolution factor of the image, thereby improving the visual perception of images
Two-Dimensional Analytical Modeling of Fully Depleted Short-Channel DG SOI MOSFET

In this paper a two-dimensional (2-D) analytical model for the surface potential variation along the channel in a fully depleted dual¿gate silicon-on-insulator MOSFETs is proposed to investigate the short-channel effects (SCEs). We demonstrate that the surface potential in the channel region exhibits a step function which causes the screening of the drain potential by the gate near the drain resulting in suppressed SCEs like hot-carrier effect and drain-induced barrier-lowering (DIBL).
Frequency scaling of molybdenum disulfide (MoS2) two-dimensional (2D) nanomechanical resonators

Molybdenum disulfide (MoS2) is a layered material that has attractive potential for enabling ultrascaled two-dimensional (2D) nanostructures and nanosystems for future electronics, optoelectronics, and sensors applications. It also has superb mechanical properties, being ~30 times stronger than steel and has intrinsic strain limit up to ~10-20%. These make MoS2 a particularly interesting material for building novel 2D nanoelectromechanical systems (NEMS). Here we demonstrate ultrathin 2D NEMS resonators based on drumhead-structured MoS2 diaphragms suspended on circular microtrenches, vibrating at high and very high frequencies (HF & VHF). We show that the resonance frequency can be tuned by adjusting parameters such as built-in tension and dimensions of the MoS2 devices. In combination with analytical and computational modeling, we identify in these devices the elastic transition regime between the membrane and plate limits, which leads to a clear roadmap for frequency scaling of MoS2 NEMS resonators.
Effect of Meltdown and Spectre Patches on the Performance of HPC Applications

In this work we examine how the updates addressing Meltdown and Spectre vulnerabilities impact the performance of HPC applications. To study this we use the application kernel module of XDMoD to test the performance before and after the application of the vulnerability patches. We tested the performance difference for multiple application and benchmarks including: NWChem, NAMD, HPCC, IOR, MDTest and IMB. The results show that although some specific functions can have execution times decreased by as much as 74%, the majority of individual metrics indicates little to no decrease in performance. The real-world applications show a 2-3% decrease in performance for single node jobs and a 5-11% decrease for parallel multi node jobs.
The Post-Observation Conference: Key to Teacher Improvement.

vades elementary and secondary education. Yet, while educators diligently examine teaching and supervision, one critical component the post-observation conference remains virtually ignored. We seem to have forgotten that improving teaching performance depends not only on supervisors' ability to analyze and assess pedagogy, but also on their ability to motivate teachers to examine their own effectiveness in the classroom. Perhaps it is selective forgetting, for the sparse research on the subject indicates that the supervisory conference is not likely to be an occasion that produces teacher growth (Blumberg, 1970). In fact, Blumberg, one of the few acknowledged experts in the area, has suggested eliminating the visitation-conference cycle. The lack of success of the supervisory conference is hardly surprising: There is no articulated process to guide practitioners nor is there salient preparatory or inservice training. Supervisory conferences, however, can make a difference if they are conducted in a systematic manner by supervisors able to exhibit behaviors consistent with sound human relations and management principles.
Human gait modeling: dealing with holonomic constraints

Dynamical models are fundamental for the study of human gait. This work presents a complete and systematic approach to deriving control system models for both the single support phase and the double support phase of a gait cycle. We consider a nine segment model in the sagittal plane. Emphasis is placed on two important aspects of the modeling process: dealing with the holonomic constraints and dealing with the ground reaction forces. We start with a raw model which is a direct result of Newton's law and which is subject to holonomic constraints. By characterizing the ground reaction forces, these constraints are eliminated to generate standard control system models for every possible situation in a gait cycle. These models are verified via both inverse dynamics and forward simulations on experimental data.
