Survey on audiovisual emotion recognition: databases, features, and data fusion strategies

Emotion recognition is the ability to identify what people would think someone is feeling from moment to moment and understand the connection between his/her feelings and expressions. In today's world, human–computer interaction (HCI) interface undoubtedly plays an important role in our daily life. Toward harmonious HCI interface, automated analysis and recognition of human emotion has attracted increasing attention from the researchers in multidisciplinary research fields. In this paper, a survey on the theoretical and practical work offering new and broad views of the latest research in emotion recognition from bimodal information including facial and vocal expressions is provided. First, the currently available audiovisual emotion databases are described. Facial and vocal features and audiovisual bimodal data fusion methods for emotion recognition are then surveyed and discussed. Specifically, this survey also covers the recent emotion challenges in several conferences. Conclusions outline and address some of the existing emotion recognition issues.
Formulation and Release Behavior of Diclofenac Sodium in Compritol 888 Matrix Beads Encapsulated in Alginate

Sustained-release polymer beads containing diclofenac sodium (DNa) dispersed in Compritol 888 and encapsulated in calcium alginate shell were prepared utilizing 23 factorial design. The effect of sodium alginate concentration, drug:Compritol 888 weight ratio and CaCl2 concentration on drug content (%), time for 50% and 80% of the drug to be released, and mean dissolution time (MDT) were evaluated with analysis of variance (ANOVA). An increase in the level of all these factors caused retardation in the release, and t50%, t80%, and MDT were increased. The drug release was dependent on the pH of the release media. A formula that gives a release comparable to commercial products was prepared.
Emergency thoracic ultrasound in the differentiation of the etiology of shortness of breath (ETUDES): sonographic B-lines and N-terminal pro-brain-type natriuretic peptide in diagnosing congestive heart failure.

OBJECTIVES Sonographic thoracic B-lines and N-terminal pro-brain-type natriuretic peptide (NT-ProBNP) have been shown to help differentiate between congestive heart failure (CHF) and chronic obstructive pulmonary disease (COPD). The authors hypothesized that ultrasound (US) could be used to predict CHF and that it would provide additional predictive information when combined with NT-ProBNP. They also sought to determine optimal two- and eight-zone scanning protocols when different thresholds for a positive scan were used. METHODS This was a prospective, observational study of a convenience sample of adult patients presenting to the emergency department (ED) with shortness of breath. Each patient had an eight-zone thoracic US performed by one of five sonographers, and serum NT-ProBNP levels were measured. Chart review by two physicians blinded to the US results served as the criterion standard. The operating characteristics of two- and eight-zone thoracic US alone, compared to, and combined with NT-ProBNP test results for predicting CHF were calculated using both dichotomous and interval likelihood ratios (LRs). RESULTS One-hundred patients were enrolled. Six were excluded because of incomplete data. Results of 94 patients were analyzed. A positive eight-zone US, defined as at least two positive zones on each side, had a positive likelihood ratio (LR+) of 3.88 (99% confidence interval [CI] = 1.55 to 9.73) and a negative likelihood ratio (LR-) of 0.5 (95% CI = 0.30 to 0.82), while the NT-ProBNP demonstrated a LR+ of 2.3 (95% CI = 1.41 to 3.76) and LR- of 0.24 (95% CI = 0.09 to 0.66). Using interval LRs for the eight-zone US test alone, the LR for a totally positive test (all eight zones positive) was infinite and for a totally negative test (no zones positive) was 0.22 (95% CI = 0.06 to 0.80). For two-zone US, interval LRs were 4.73 (95% CI = 2.10 to 10.63) when inferior lateral zones were positive bilaterally and 0.3 (95% CI = 0.13 to 0.71) when these were negative. These changed to 8.04 (95% CI = 1.76 to 37.33) and 0.11 (95% CI = 0.02 to 0.69), respectively, when congruent with NT-ProBNP. CONCLUSIONS Bedside thoracic US for B-lines can be a useful test for diagnosing CHF. Predictive accuracy is greatly improved when studies are totally positive or totally negative. A two-zone protocol performs similarly to an eight-zone protocol. Thoracic US can be used alone or can provide additional predictive power to NT-ProBNP in the immediate evaluation of dyspneic patients presenting to the ED.
Ego-Motion Classification for Driving Vehicle

Accurate prediction of vehicle ego-motion in real time is crucial for an autonomous driving system. In this paper, we formulate the problem of ego-motion classification as video event detection, and we propose an end-to-end deep model to address this problem. In this model, we utilize Convolutional Neural Networks (CNNs) to extract semantic visual feature of each video frame, and employ a Long Short Term Memory (LSTM) to model the temporal correlation of the video streams. To study the performance of ego-motion classification, we constructed a video dataset-Campus20, which captured in general driving conditions. Experimental results on Campus20 verifies the superior performance of our proposed model over well established baselines.

Os extratos em etanol e diclorometano de uma propolis verde de Baccharis dracunculifolia foram analisados por CLAE-ICPA-EM e CG-EM, respectivamente. A tecnica de CLAE-EM-ICPA, no modo positivo, forneceu uma completa e inequivoca composicao quimica da amostra de propolis verde. Ela serve como impressao digital para amostras diferentes de propolis. A composicao do extrato em etanol consistiu fundamentalmente de acido cinâmico e derivados, flavonoides, acido benzoico e alguns benzoatos, aromaticos nao hidroxilados, e acidos e esteres alifaticos, os quais sao normalmente ignorados na literatura porque nao absorvem luz UV. Os constituintes principais do extrato em diclorometano foram compostos prenilados, alcanos e terpenoides.
Health professionals' attitudes toward the detection and management of cancer-related anorexia-cachexia syndrome, and a proposal for standardized assessment.

BACKGROUND The identification and management of patients with cancer anorexia-cachexia syndrome (CACS) can be a challenge despite recent international consensus on the definition of the condition. OBJECTIVES To describe the current views and practice patterns of community oncologists and oncology nurses in regard to CACS and to propose a standardized, pragmatic assessment of CACS for oncological practice. METHODS AND MATERIALS Responses from 151 community oncologists and nurses obtained across 5 surveys were analyzed. Questions addressed CACS in general and in patients with non-small-cell lung cancer (NSCLC). Surveys 1-3 were directed at physicians, and surveys 4 and 5 were directed at nurses. Surveys 1, 2, 4, and 5 focused on the recognition and monitoring of CACS, and Survey 3 on symptom management. RESULTS 67% of medical oncologists in Survey 3 selected weight loss as the most important criterion for diagnosing CACS and cited declining appetite and performance status (PS) as the most bothersome effects for patients and families. Weight maintenance/gain was the primary treatment objective for oncologists. Respondents to surveys 1 and 2 acknowledged the risk for CACS is high (60%) in NSCLC but considered the risk much lower (4%) in patients completing a first course of therapy with good PS. 91% of oncologists in Survey 3 reported that symptoms that had an impact on calorie intake were important/very important, and 73% were willing to consider a symptom assessment instrument that included appetite. Nurses in surveys 4 and 5 reported weight loss and appetite were most commonly used to identify cachexia. They considered responsibility for the initial assessment of cachexia was the oncologist's (32%), followed by the nurse practitioner (28%), and the nurse (16%). CONCLUSION Most oncologists and nurses recognize the core criteria for the CACS, although there may be under-recognition of the condition's prevalence, particularly earlier in the course of treatment. There is considerable interest in adopting a brief assessment tool for screening, management, and referral of patients who are affected by or at-risk of CACS.

Influence of handling or aversive stimulation during rats' neonatal or adolescence periods on oral cocaine self-administration and cocaine withdrawal

Adverse early life events may influence vulnerability for drug intake. The influence of handling or aversive stimulation during neonatal or adolescent periods on adult cocaine oral self-administration and withdrawal were investigated. Neonatal or adolescent rats were exposed to a modified unpredictable stress paradigm or handling for 10 days. When adults, oral cocaine was offered through the two-bottle choice paradigm for 30 days. Rats were submitted to the forced swimming test after cocaine withdrawal. Overall, there was a significant increase of cocaine choice throughout the days of cocaine consumption and an interaction between interventions and cocaine daily choice. Control rats started cocaine intake at a lower level and increased cocaine choice over time, while animals submitted to neonatal interventions started cocaine intake at higher levels of choice, with less increase in cocaine intake during the period of cocaine exposure. Rats receiving aversive stimulation during adolescence also started taking cocaine solution at higher levels. Significantly higher immobility duration and shorter latency to immobility during the forced swimming were detected in these same adolescents that received unpredictable stress, when compared to the control or handled rats, while there was no difference for rats stimulated neonatally. Therefore, early life events increase initial preference for cocaine and promote changes in its abuse pattern, according to the intensity of the event and the age of the individual at the time of the event. Moreover, adverse experiences during adolescence, but not in neonatal phases, increase the vulnerability to depressive-like behaviors during cocaine withdrawal of adult rats.
Maxillary sinus augmentation using different grafting materials and osseointegrated dental implants in monkeys. Part II. Evaluation of porous hydroxyapatite as a grafting material.

The aim of this study was to evaluate clinically, histologically and histometrically the use of porous hydroxyapatite (i.e. Interpore-200) as a bone grafting material for maxillary sinus augmentation procedures. In 4 adult male rhesus monkeys (i.e. Macaca mulatta) the 1st, 2nd and 3rd maxillary molars on one side of the jaws were extracted and the remaining bone between the alveolar crest and the bottom of the sinus was reduced to 3-4 mm. After 3 months, maxillary sinus augmentation procedures were performed on one side of the jaws in each monkey, and the sinuses grafted with the porous hydroxyapatite. Two IMZ titanium plasma-sprayed cylinder implants were then immediately placed into the augmented sinus (i.e. simultaneous implants-loaded group). After 4 months, 2 additional similar implants were placed into the previously augmented sinuses (i.e. delayed implants-loaded group). Four months later, the abutment connection was performed and all 4 implants were loaded with a gold-alloy bridge for 6 months (i.e. until sacrifice). The contralateral side of each monkey received the same treatment with the exception that the extractions were performed 7 months after those in the opposite side and that the implants in this side were not loaded. Thus, 2 additional study groups (i.e. simultaneous implants-unloaded group and delayed implants-unloaded group) were obtained. Clinically, all loaded implants were stable at the day of sacrifice. Histologic analysis demonstrated a significant amount of new bone formation in the augmented sinuses. Porous hydroxyapatite graft particles appeared to be integrated to the new bone. The percentage of direct mineralized bone-to-implant contact in the augmented area was greater on the delayed-placed implants than on the simultaneously-placed implants. Also, the percentage of direct mineralized bone-to-implant contact was greater in the residual bone than in the augmented area. It was concluded that this porous hydroxyapatite bone graft enhanced bone formation and bone-to-implant contact in the augmented sinuses and that the delayed implant placement in combination with the sinus augmentation procedure appears to result in a higher percentage of direct mineralized bone-to-implant contact.
Microsatellite spreading in the human genome: evolutionary mechanisms and structural implications.

Microsatellites are tandem repeat sequences abundant in the genomes of higher eukaryotes and hitherto considered as "junk DNA. " Analysis of a human genome representative data base (2.84 Mb) reveals a distinct juxtaposition of A-rich microsatellites and retroposons and suggests their coevolution. The analysis implies that most microsatellites were generated by a 3'-extension of retrotranscripts, similar to mRNA polyadenylylation, and that they serve in turn as "retroposition navigators," directing the retroposons via homology-driven integration into defined sites. Thus, they became instrumental in the preservation and extension of primordial genomic patterns. A role is assigned to these reiterating A-rich loci in the higher-order organization of the chromatin. The disease-associated triplet repeats are mostly found in coding regions and do not show an association with retroposons, constituting a unique set within the family of microsatellite sequences.
Facilitating Asian students' critical thinking in online discussions

The purpose of the study reported here is to illustrate how an approach based on a culturally appropriate ‘shepherd metaphor’ has helped Asian students to cross cultural boundaries and to engage in critical thinking online. Asian students are under different levels of influence from the Confucian Heritage Culture, which cultivates students to revere authority, maintain harmony and avoid conflicts in public. This has a significant impact on Asian students' cultural readiness to verbalise critical thinking. This paper partially reports research undertaken in a large English as a Foreign Language reading class in Taiwan, in which ‘shepherd leadership’ was practised. Shepherd leadership involves knowing students individually, offering cognitive modelling, exercising leadership and discipleship, encouraging student leadership and calling on silent students personally to get them to participate. This approach, concentrating on Asian students' affective needs, cognitive modelling, passing leadership to students and reaching out to silent ones, was found effective. [ABSTRACT FROM AUTHOR]
Glucocorticoids and TNFα Interact Cooperatively to Mediate Sepsis-Induced Leucine Resistance in Skeletal Muscle

Sepsis blunts the ability of nutrient signaling by leucine to stimulate skeletal muscle protein synthesis by impairing translation initiation. The present study tested the hypothesis that overproduction of either tumor necrosis factor (TNF)-α or glucocorticoids mediate the sepsis-induced leucine resistance. Prior to producing peritonitis, rats received either vehicle, TNF binding protein (TNFBP) to inhibit endogenous TNFα action, and/or the glucocorticoid receptor antagonist RU486. Leucine was orally administered to all rats 24 h thereafter and the gastrocnemius removed 20 min later to assess protein synthesis and signaling components important in controlling peptide-chain initiation. Muscle protein synthesis was 65% lower in septic rats administered leucine than in leucine-treated control animals. This reduction was not prevented by either TNFBP or RU486 alone, but was completely reversed by the combination. This sepsis-induced leucine resistance was associated with an 80% reduction in the amount of active eIF4E·eIF4G complex, a 5-fold increase in the formation of the inactive eIF4E·4E-BP1 complex as well as markedly reduced (at least 70%) phosphorylation of 4E-BP1, eIF4G, S6K1, S6, and mTOR. Pretreatment of septic rats with either TNFBP or RU486 individually only nominally improved the leucine action as assessed by the above-mentioned endpoints. In contrast, when TNFBP and RU486 were co-administered, the ability of sepsis to impair the leucine-stimulated phosphorylation of 4E-BP1, eIF4G, S6K1, and S6 as well as the redistribution of eIF4E was essentially prevented. No differences in the total amount or phosphorylation of eIF2α and eIF2Bε were detected between the different groups, and changes could not be attributed to differences in the prevailing plasma concentration of insulin or leucine. Our data demonstrate the sepsis-induced leucine resistance in skeletal muscle results from the cooperative interaction of both TNFα and glucocorticoids.
Venous Thromboembolism in Trauma Patients

Serial venous duplex scans (VDS) were done in 507 trauma patients with at least one risk factor (RF) for venous thromboembolism (VTE) during a 2-year study period. Deep vein thrombosis (DVT) was detected in 31 (6.1%) patients. This incidence was 3.1 per cent in low (1–2 RFs), 3.4 per cent in moderate (3–5 RFs), and 7.7 per cent in high (≥6 RFs) VTE scores (P = 0.172). Incidence was statistically different (3% vs 7.2%, P = 0.048) on reanalyzing patients in two risk categories, low-risk (1–4 RFs) and high-risk (≥5 RFs). Only 4 of 16 RFs had statistically higher incidence of DVT in patients with or without RFs: previous VTE (27.3% vs 5.6%, odds ratio (OR) 6.628, P = 0.024), spinal cord injury (22.6% vs 5%, OR 5.493, P = 0.001), pelvic fractures (11.4% vs 5.1%, OR 2.373, P = 0.042), and head injury with a greater than two Abbreviated Injury Score (10.5% vs 4.2%, OR 2.639, P = 0.014). On reanalyzing patients with ≥5 RFs vs <5RFs, obesity (14.3 vs 6.1%, P = 0.007), malignancy (5.6% vs 0.6%, P = 0.006), coagulopathy (10.8% vs 1.8%, P = 0.000), and previous VTE (3.2% vs 0%, P = 0.019) were significant on univariate analysis. Patients with DVT had 3.70 ± 1.75 RFs and a 9.61 ± 4.93 VTE score, whereas, patients without DVT had 2.66 ± 1.50 RFs and a 6.83 ± 3.91 VTE score (P = 0.000). DVTs had a direct positive relationship with higher VTE scores, length of stay, and number of VDS (>1 r, P ≤ 0.001). Increasing age was a weak risk factor (0.03 r, P = 0.5). First two VDS diagnosed 77 per cent of DVTs. Patients with injury severity score of ≥15 and 25 had higher DVTs compared with the ones with lower injury severity score levels (P ≤ 0.05). Pulmonary embolism was silent in 63 per cent and DVTs were asymptomatic in 68 per cent.
Improved survival in HIV-infected African-Americans with ESRD.

AIMS To determine if there has been improvement in survival of HIV-infected patients with end-stage renal failure subsequent to widespread use of highly active antiretroviral therapy. METHODS The United States Renal Data System is a national data system funded by the National Institute of Diabetes and Digestive and Kidney Disease with the Centers for Medicare and Medicaid. Using the United States Renal Data System Standard Analysis Files, we analyzed all African-American end-stage renal failure patients in the United States from 1990-2001. We compared survival rates for patients with HIV disease, sickle cell anemia, diabetes, and all other diagnoses for the time periods 1990-1994 and 1995-2001. The main outcome measure was one- and five-year survival in each cohort. RESULTS One-year survival of African-American patients with end-stage renal disease and HIV increased from 46.6% during 1990-1994 to 65.1% during 1995-2001 (odds ratio 2.139). One-year survival decreased in the sickle cell group (odds ratio 0.595) and decreased slightly in the diabetic group (odds ratio 0.927) and all others (odds ratio 0.941). Five-year survival in the HIV group increased from 13.3% in 1990-1995 to 30.4% in 1995-2001 (odds ratio 2.847). There was no corresponding increase in survival for the sickle cell group (odds ratio 0.987), the diabetic group (odds ratio 1.06), or all others (odds ratio 1.137). CONCLUSIONS We conclude that survival in African-American end-stage renal disease patients and HIV infection has substantially improved subsequent to introduction of highly active antiretroviral therapy. Our data support aggressive multi-drug treatment of end-stage renal failure patients with HIV infection.
Interaction between Self-Efficacy and Initial Performance in Predicting the Complexity of Task Chosen

Research on motivation has confirmed the predictive power of cognitive-affective variables on performance in complex tasks. However, less attention has been given to the determinants of task choice in situations where there is discretion about which task is to be undertaken. An experimental study was designed to analyze the role of dispositional variables (goal orientations and need for cognition) and self-regulatory variables (self-efficacy, intrinsic satisfaction, and task involvement) in the complexity of task chosen. 117 students participated in a complex decision-making task with different levels of difficulty. Results indicated that the avoidance performance goal orientation can predict the difficulty of the task chosen. Self-efficacy beliefs contribute to explaining the range of difficulty people consider feasible to attempt when initial performance is controlled. Individuals with high self-efficacy chose tasks that maximized their learning opportunities.
