The “Reading the Mind in Films” Task: Complex emotion recognition in adults with and without autism spectrum conditions

Abstract Background: Individuals with autism spectrum conditions (ASC) have difficulties recognizing mental states in others. Most research has focused on recognition of basic emotions from faces and voices separately. This study reports the results of a new task, assessing recognition of complex emotions and mental states from social scenes taken from feature films. The film format arguably is more challenging and ecologically closer to real social situations. Sample and method: A group of adults with ASC (n=22) were compared to a group of matched controls from the general population (n=22). Participants were tested individually. Results: Overall, individuals with ASC performed significantly lower than controls. There was a positive correlation between verbal IQ and task scores. Using task scores, more than 90% of the participants were correctly allocated to their group. Item analysis showed that the errors individuals with ASC make when judging socioemotional information are subtle. Conclusions: This new test of complex emotion and mental state recognition reveals that adults with ASC have residual difficulties in this aspect of empathy. The use of language-based compensatory strategies for emotion recognition is discussed.
On effective superpotentials and compactification to three dimensions

We study four dimensional = 2 SO/SP supersymmetric gauge theory on R3 × S1 deformed by a tree level superpotential. We will show that the exact superpotential can be obtained by making use of the Lax matrix of the corresponding integrable model which is the periodic Toda lattice. The connection between vacua of SO(2N) and SO(2kN−2k+2) can also be seen in this framework. Similar analysis can also be applied for SO(2N+1) and SP(2N).
Current Diagnostic Techniques of Assessing Myocardial Viabilit in Patients With Hibernating and Stunned Myocardium

T he differentiation of viable from nonviable myocardium in patients with coronary artery disease and left ventricular dysfunction is an issue of increasing clinical relevance in the current era of myocardial revascularization. It is now well established that impaired left ventricular function does not always represent an irreversible process. However, until recently, determining whether impaired regional or global left ventricular function at rest was a potentially reversible process could be made only retrospectively, after the patient had undergone coronary artery angioplasty or bypass surgery.1-6 Because enhanced left ventricular function after revascularization is associated with improved survival,7-9 diagnostic procedures that identify reversible asynergy prospectively may provide significant prognostic information. Thus, the accurate distinction between viable and scarred or necrotic myocardium has important clinical implications, especially in patients who are being considered for interventional therapy. In the past, coronary artery patency and preserved regional contractile function were used to identify viable myocardium. However, the inadequacy of an occluded epicardial coronary artery to predict nonviable myocardium was realized when coronary collateral circulation was shown to be capable of sustaining myocardial function at rest10-12 and even during exercise.12-14 Conversely, a patent coronary artery after thrombolytic therapy is insufficient evidence that the dysfunctional myocardium perfused by this artery is viable.15 Electrocardiographic criteria for viability are also imprecise. Although left ventricular function after revascularization is more likely to improve in patients with non-Q wave rather than Q wave infarctions,16 electrocardiographic Q wave criteria are not specific for determining the extent of scarred or viable myocardium after myocardial infarction.3,17-19 Similarly, both animal and clinical studies have also demonstrated that regional myocardial contractile function does not reliably distinguish viable myocardium from nonviable myocardium.20-24 It has been shown that under certain conditions, when viable myocytes are subjected to ischemia, prolonged alterations in myocyte
Transient analysis of self-excited induction Generator with electronic load controller (ELC) supplying static and dynamic loads

This paper presents a transient analysis of a self-excited induction generator (SEIG) with electronic load controller (ELC) used in stand-alone micro-hydro power generation employing uncontrolled turbines. In view of the need to feed both dynamic [three-phase induction motor (IM)] and static loads from such systems, the transient behavior due to switching in of such loads is of interest and is carried out here. A composite mathematical model of the total system has been developed by combining the modeling of prime mover, SEIG, ELC, and load. Simulated results are compared with the experimental ones, obtained on a developed prototype of an SEIG-ELC system for the starting of an IM and switching in a resistive load. For the starting of an IM, a star/delta starter is used to avoid inrush current. Harmonic analysis is carried out to find total harmonic distortion of the terminal voltage and current to assess its power quality.
A Novel Peptide for Simultaneously Enhanced Treatment of Head and Neck Cancer and Mitigation of Oral Mucositis

We have characterized a novel 21 amino acid-peptide derived from Antrum Mucosal Protein (AMP)-18 that mediates growth promotion of cultured normal epithelial cells and mitigates radiation-induced oral mucositis in animal models, while suppressing in vitro function of cancer cells. The objective of this study was to evaluate these dual potential therapeutic effects of AMP peptide in a clinically relevant animal model of head and neck cancer (HNC) by simultaneously assessing its effect on tumor growth and radiation-induced oral mucositis in an orthotopic model of HNC. Bioluminescent SCC-25 HNC cells were injected into the anterior tongue and tumors that formed were then subjected to focal radiation treatment. Tumor size was assessed using an in vivo imaging system, and the extent of oral mucositis was compared between animals treated with AMP peptide or vehicle (controls). Synergism between AMP peptide and radiation therapy was suggested by the finding that tumors in the AMP peptide/radiation therapy cohort demonstrated inhibited growth vs. radiation therapy-only treated tumors, while AMP peptide-treatment delayed the onset and reduced the severity of radiation therapy-induced oral mucositis. A differential effect on apoptosis appears to be one mechanism by which AMP-18 can stimulate growth and repair of injured mucosal epithelial cells while inhibiting proliferation of HNC cells. RNA microarray analysis identified pathways that are differentially targeted by AMP-18 in HNC vs. nontransformed cells. These observations confirm the notion that normal cells and tumor cells may respond differently to common biological stimuli, and that leveraging this finding in the case of AMP-18 may provide a clinically relevant opportunity.
Translating Principles of Effective Feedback for Students into the CS1 Context

Learning the first programming language is challenging for many students. High failure rates and bimodally distributed grades lead to a pedagogical interest in supporting students in first-year programming courses (CS1). In higher education, the important role of feedback for guiding the learning process and improving the learning outcome is widely acknowledged. This article introduces contemporary models of effective feedback practice as found in the higher education literature and offers an interpretation of those in the CS1 context. One particular CS1 course and typical course components are investigated to identify likely loci for feedback interventions and to connect related computer science education literature to these forms of feedback.
Phytoplankton production in the Delaware Estuary : temporal and spatial variability

Phytoplankton production in the Delaware Estuary (USA) was measured over several seasonal cycles (1980-1985). Seasonal variability in daily area1 production (JP; g C m-2 dl ) was dlrectly related to chlorophyll concentrations in the upper estuary, ranging from a maximum of 1.1 g C m-' d ' In summer to a minlmum of <O.l g C m-2 d-l in winter. In the mid and lower estuary, maximum JP occurred during 2 periods: at the estuary mouth (4 .2 g C m > d-l) dunng summer in the presence of low phytoplankton biomass (2 to 10 kg Chl I ' ) , and in mid-estuary [2.6 g C d-l) during the spring diatom bloom (50 to 60 yg Chll-l). Desplte the occurrence of maximum nutnent concentrations in the freshwater region, highest JP and 90 % of the annual production occurred in the lower estuary, down-stream from the turbidity maximum. The presence of the turbidity maximum immediately downstream from major anthropogenic nutrient sources restricts phytoplankton growth, and limits biomass accumulation below nuisance levels. Annual production for the 1981-1985 period averaged 307 g C and displayed marked inter-annual variability. Llght availability is the predominant regulator of production in the estuary. Although growth was light-limited, neither chlorophyll specific produchon nor the light intensity at which photosynthesis saturates was related to the mean light intensity in the mixed surface-layer. These results suggest that photoadaptive response times are slower than the vertical mlxing rate and that photoadaptation is of mlnor significance to overall production in the system.
Spatial Orientation And Distribution Of Reservoir Fractures From Scattered Seismic Energy

Wepresentthedetailsofanewmethodfordeterminingthereflection and scattering characteristics of seismic energy from subsurface fractured formations. The method is based upon observations we have made from 3D finite-difference modeling of the reflected and scattered seismic energy over discrete systems of vertical fractures. Regularly spaced, discrete vertical fracture corridors impart a coda signature, which is a ringing tail of scatteredenergy,toanyseismicwaveswhicharetransmittedthrough or reflected off of them. This signature varies in amplitude and coherence as a function of several parameters including: 1 the difference in angle between the orientation of the fractures and the acquisition direction, 2 the fracture spacing, 3 the wavelength of the illuminating seismic energy, and 4 the compliance, or stiffness, of the fractures. This coda energy is most coherent when the acquisition direction is parallel to the strike of thefractures.Ithasthelargestamplitudewhentheseismicwavelengths are tuned to the fracture spacing, and when the fractures have low stiffness.

Combined unsigned and two's complement squarers

Squaring is an important operation in digital signal processing applications. For several applications, a significant reduction in area, delay, and power consumption is achieved by performing squaring using specialized squarers, instead of multipliers. Although most previous research on parallel squarers focuses on the design of unsigned squarers, squaring of two's complement numbers is also often required. This paper presents the design of parallel squarers that perform either unsigned or two's complement squaring, based on an input control signal. Compared to unsigned parallel squarers, these squarers require only a small amount of additional delay and area.
Dietary Nitrate Is a Modifier of Vascular Gene Expression in Old Male Mice

Aging leads to a number of disadvantageous changes in the cardiovascular system. Deterioration of vascular homoeostasis with increase in oxidative stress, chronic low-grade inflammation, and impaired nitric oxide bioavailability results in endothelial dysfunction, increased vascular stiffness, and compromised arterial-ventricular interactions. A chronic dietary supplementation with the micronutrient nitrate has been demonstrated to improve vascular function. Healthy dietary patterns may regulate gene expression profiles. However, the mechanisms are incompletely understood. The changes that occur at the gene expression level and transcriptional profile following a nutritional modification with nitrate have not been elucidated. To determine the changes of the vascular transcriptome, we conducted gene expression microarray experiments on aortas of old mice, which were treated with dietary nitrate. Our results highlight differentially expressed genes overrepresented in gene ontology categories. Molecular interaction and reaction pathways involved in the calcium-signaling pathway and the detoxification system were identified. Our results provide novel insight to an altered gene-expression profile in old mice following nitrate supplementation. This supports the general notion of nutritional approaches to modulate age-related changes of vascular functions and its detrimental consequences.
Computation of secrecy capacity for more-capable channel pairs

We prove that the Arimoto-Blahut like algorithm provided by Yasui et al [6] to solve for the Secrecy Capacity of a less-noisy Discrete Memoryless Channel (DMC) pair can be extended to a more-capable DMC pair subject to the availability of a suitable initial guess. In particular, we show that if a cut parallel to the input hyperplane removes a convex piece from the graph of the multi-input function f(q)=I(X;Y) - I(X; Z)rfloorq(x), where q is the input probablity distribution, then for any initial guess chosen within that convex piece, Yasui's algorithm will converge to the optimal value in that convex piece. We then introduce a new characterization called quasiconcavity of a DMC pair and show that it lies between the less-noisy and more-capable characterizations. We also show that in the binary case, quasiconcavity is equivalent to the more-capable characterization. We then show that we can choose from a wider range of initial guesses by looking at regions around the optimal point where the function is quasiconcave. Finally we establish that the algorithm of Yasui et al can be used for more-capable channel pairs with binary alphabets.
Presynaptic inhibition of the release of multiple major central nervous system neurotransmitter types by the inhaled anaesthetic isoflurane.

BACKGROUND Presynaptic effects of general anaesthetics are not well characterized. We tested the hypothesis that isoflurane exhibits transmitter-specific effects on neurotransmitter release from neurochemically and functionally distinct isolated mammalian nerve terminals. METHODS Nerve terminals from adult male rat brain were prelabelled with [(3)H]glutamate and [(14)C]GABA (cerebral cortex), [(3)H]norepinephrine (hippocampus), [(14)C]dopamine (striatum), or [(3)H]choline (precursor of [(3)H]acetylcholine; striatum). Release evoked by depolarizing pulses of 4-aminopyridine (4AP) or elevated KCl was quantified using a closed superfusion system. RESULTS Isoflurane at clinical concentrations (<0.7 mM; ~2 times median anaesthetic concentration) inhibited Na(+) channel-dependent 4AP-evoked release of the five neurotransmitters tested in a concentration-dependent manner. Isoflurane was a more potent inhibitor [expressed as IC(50) (SEM)] of glutamate release [0.37 (0.03) mM; P<0.05] compared with the release of GABA [0.52 (0.03) mM], norepinephrine [0.48 (0.03) mM], dopamine [0.48 (0.03) mM], or acetylcholine [0.49 (0.02) mM]. Inhibition of Na(+) channel-independent release evoked by elevated K(+) was not significant at clinical concentrations of isoflurane, with the exception of dopamine release [IC(50)=0.59 (0.03) mM]. CONCLUSIONS Isoflurane inhibited the release of the major central nervous system neurotransmitters with selectivity for glutamate release, consistent with both widespread inhibition and nerve terminal-specific presynaptic effects. Glutamate release was most sensitive to inhibition compared with GABA, acetylcholine, dopamine, and norepinephrine release due to presynaptic specializations in ion channel expression, regulation, and/or coupling to exocytosis. Reductions in neurotransmitter release by volatile anaesthetics could contribute to altered synaptic transmission, leading to therapeutic and toxic effects involving all major neurotransmitter systems.
Searching for Additional Heating: [O II] Emission in the Diffuse Ionized Gas of NGC 891, NGC 4631, and NGC 3079

We present spectroscopic data of ionized gas in the disk-halo regions of three edge-on galaxies, NGC 891, NGC 4631, and NGC 3079, covering a wavelength range from [O II] 3727 Å to [S II] 6716.4 Å. The inclusion of the [O II] emission provides new constraints on the properties of the diffuse ionized gas, in particular the origin of the observed spatial variations in the line-intensity ratios. We used three different methods to derive electron temperatures, abundances, and ionization fractions along the slit. The increase in the [O II]/Hα line ratio toward the halo in all three galaxies requires an increase in either electron temperature or oxygen abundance. Keeping the oxygen abundance constant yields the most reasonable results for temperature, abundances, and ionization fractions. Since a constant oxygen abundance seems to require an increase in temperature toward the halo, we conclude that gradients in the electron temperature play a significant role in the observed variations in the optical line ratios from extraplanar diffuse ionized gas in these three spiral galaxies.
Analyze Me: Open Learner Model in an Adaptive Web Testing System

This paper presents the open learner modelling capabilities offered by an adaptive web testing tool. Adaptation decisions are based on user customizable compound rules requiring the identification of several learner characteristics which are then displayed graphically and textually to learners and educators. The open learner modelling capabilities include anonymous access to models of peers and restricted named access to friend peers. Opening the learner profiles supports learner and educator involvement in decision making so as to create a more credible learner model. The educational advantages of the open learner modelling capabilities are discussed on the basis of an evaluative study.
Relationship between Detoxification Time and Mental Symptoms of Heroin Addicts

Objective: To study the relationship between detoxification time and the mental symptoms of heroin addicts. Methods: SCL-90 scales were used to assess the mental symptoms in heroin addicts in different periods of detoxification. Results: There were significant differences (P 0.05) in somatization, depression, anxiety, interpersonal sensitivity, phobias and paranoia among the 1-month group, 2-month group, 3-6-month group and over 6-month group. Psychosis and sleeping-diet disorders showed significant differences between groups of 2-month and over 6-month groups. There are significant differences in obsessional symptoms among the 1-month group, 2-month group, 3-6 month group, and over 6-month group. Hostility shows differences between the 1-month group and the 3-6-month group. Mean scores in the over 6-month group in interpersonal sensitivity, depression, anxiety, hostility are higher than those in the 3-6-month group. Conclusion: (1) 2 months are needed to recover from somatization, depression, anxiety, psychosis and sleeping-diet disorders. (2) 3 months are needed to recover from obsession, interpersonal sensitivity, phobias and paranoia. (3) 3-6 months are needed to recover from hostility. Some mental stress factors can lead to hostility or other emotions in addicts in mental rehabilitation.
Effect of Axial Eye Length on Retinal Vessel Parameters in 6 to 12-Year-Old Malay Girls

Purpose Retinal vessel analysis is affected by both systemic and ocular factors. Malays are the major ethnicity in South East Asia. Data on the retinal microvasculature in Malays is limited, especially among children. We aim to evaluate the influence of ocular biometry on retinal vessel parameters in young Malay girls. Methods This was a cross-sectional, hospital-based study involving 86 Malay girls aged 6 to 12 years old in Hospital Universiti Sains Malaysia from 2015–2016. Ocular examination, refraction, biometry, retinal photography, and anthropometric measurements were performed. The central retinal arteriolar equivalent (CRAE), central retinal venular equivalent (CRVE) and overall fractal dimension (Df) were measured using validated computer-based methods (Singapore I vessel analyzer, SIVA version 3.0, Singapore). The associations of ocular biometry and CRAE, CRVE and Df were analyzed using multivariable analysis. Results The mean CRAE, CRVE and Df in Malay girls were 171.40 (14.40) um, 248.02 (16.95) um and 1.42 (0.05) respectively. Each 1 mm increase in axial length was associated with a reduction of 4.25 um in the CRAE (p = 0.03) and a reduction of 0.02 in the Df (p = 0.02), after adjustment for age, blood pressure and body mass index. No association was observed between axial length and CRVE. Anterior chamber depth and corneal curvature had no association with CRAE, CRVE or Df. Conclusion Axial length affects retinal vessel measurements. Narrower retinal arterioles and reduced retinal fractal dimension were observed in Malay girls with longer axial lengths.
The Imagework Method in Health and Social Science Research

Existing alongside the traditional forms of qualitative social science research, there is a set of potential research methods that derive from experiential groupwork and the humanistic human potential movement and are only slightly used by researchers. Social science research has barely begun to use these powerful strategies that were developed originally for personal and group change but that are potentially applicable to the research domain. This article will locate these methods within the qualitative research domain and propose a novel view of their value. The study of the actual and potential use of one of these methods, imagework, will be the particular focus of this article. References to the use of artwork, sculpting, psychodrama, gestalt, and dreamwork will also be made. The hypothesis underpinning the author’s approach is that experiential research methods such as imagework can elicit implicit knowledge and self-identities of respondents in a way that other methods cannot.
