Audio-visual emotion recognition for natural human-robot interaction

Since the computer has conquered our life and became an essential need rather than an accessory, more-sophisticated human-computer interaction, beyond the traditional keyboard, mouse, and monitor, is aimed to enable the users to interact with computers more socially. Emotional interaction play a major role in social life, thus the affective humanrobot interaction has evolved significantly throughout the last decades. The aim of this thesis is to provide the ability of emotion understanding for a robot. Throughout the thesis, a discrete theory of emotions is used as a frame of reference. According to it, emotions can be classified into some basic emotion classes. The research is orginized around two goals. The first goal is to enable a robot to infer the emotional state of its interaction partner by analysing the displayed facial expression in non-constrained conditions. To achieve that, a robust, fully automatic, non-invasive, and real-time applicable vision-based system is developed with the ability to be implemented in the robot. As the aim is to enable the robot to interact with its interactant in eal-world scenarios, sitautions in which the user is engaged in conversational sessions present farther challange for such systems. The second goal of this work is to combine facial expression and speech information cues in such a way, as to enable the affective system of the robot to fit such situations. En route to this goal possible affects of facial configuration related to speech on inferring emotions from facial expression is investigated. The results suggest a degraded performance when facial expressions are displyed during speech as displying them deliberately. In order to smooth this effect, information of audio signal is taken into account. The performance of the emotion recognition system is relatively enhanced by fusing facial expression cues and speech information ones into a bimodal system. The perfomance of the bimodal system still, however, degraded comparing with the perfomance stand-alone facial expression analyis system in the case of displayning facial expression deliberately. Finally, the extent of recognizing each emotion by utilizng each modality is invistagted. The results indicate a highly varying performance of each modality ith the respective emotion class, and for the bimodal system, each modality should be weighted according to its discriminative power for a specific emotion.
Are Creative Individuals Bad Apples? A Dual Pathway Model of Unethical Behavior

Research has been inconsistent in its quest to discover whether dispositional creativity is associated with more or less unethical behavior. Drawing on social cognitive theory, we propose that moral disengagement and moral imagination are 2 parallel mechanisms that encourage or inhibit unethical behavior, and that which of these mediation processes occur depends on moral identity. Study 1, a 3-wave study of a food service organization, shows that employees high on both dispositional creativity and moral identity are less likely to be morally disengaged and behave less unethically. The results of Study 2 replicate Study 1’s findings in a scenario-based study of college students, and further show that individuals who are high on both dispositional creativity and moral identity are more likely to be morally imaginative and to behave less unethically. Theoretical and practical implications of our model are discussed.
Aqueous-Phase Diffusion in Unsaturated Geologic Media: A Review

Aqueous-phase diffusion in geologic media is very important in agricultural production, contaminant transport and remediation, risk assessment, and waste disposal. This review was undertaken to investigate (1) the components of effective diffusion coefficients, (2) diffusion as a function of water content and diffusion models, as well as the effects of temperature, compactness, and sorption on diffusion, and (3) diffusion in aggregated media. We focus on the behavior of, and relationship between, nonsorbing diffusion species and water content, particularly in porous aggregates. At low water content, aqueous-phase diffusion occurs in thin liquid films on particle surfaces, and diffusion is very slow. Diffusion is monotonically related to water content, but the relationship is not simple and depends on the range of water contents (e.g., the different forms of relationships at different water-content ranges). Data from the scientific literature further show that such relationship is related to the texture (pore-size distribution) of the geologic medium. In this article, we compile the available models that describe the relationship between diffusion coefficient and water content, with some models incorporating parameters related to medium properties. Temperature dependence of diffusion is related to the viscosity change of water at different temperatures. We note that the effects of water content on interacting sorption and diffusion deserve further investigation. Our investigation showed that, for porous aggregated media such as tuff gravel, the total water content is comprised of surface water (inter-aggregate regions) and internal water (intra-aggregate regions). Surface film water around particles and pendular water between the aggregate contacts serve as the predominant diffusion pathways. Diffusion in tuff gravel could be very slow, because water films on surfaces could be discontinuous or absent. Finally, future directions regarding the testing of aqueous-phase diffusion in complex systems (e.g., unsaturated porous aggregates) are offered.
Treewidth of the Line Graph of a Complete Graph

In recent articles by Grohe and Marx, the treewidth of the line graph of a complete graph is a critical example—in a certain sense, every graph with large treewidth “contains” L(Kn) . However, the treewidth of L(Kn) was not determined exactly. We determine the exact treewidth of the line graph of a complete graph.
Discussion on influencing factors of the pulse-jet performance of fabric filter

In this study, we establish a numerical model and use computational fluid dynamics (CFD) analysis to measure peak pressure on the surface of filter bag. The numerical results are in good agreement with the experimental data during the pulse cleaning process. Peak pressure on the surface of filter bag, pressure rise rate and maximum reverse acceleration are used as evaluation indicators of bag-cleaning intensity. The filter bag peak pressure, pressure rise rate and maximum reverse acceleration along the length direction of filter bag during the pulse cleaning process are analyzed under different pulse-jet pressure, different pulse-jet distance, different length of filter bag, different pulse-jet time and for different diameter of nozzle. The results show that three evaluation indicators are consistent along with the change tendency of various factors. The evaluation indicators all have remarkable drop along with the filter bag length increasing, and increase as the nozzle diameter and the injection pressure increase. It provides optimal ranges of pulse-jet distance and pulse-jet time, such as pulse-jet distance is at 250 mm, and pulse-jet time is in 70∼100 ms. The design length of filter bag unfavorably exceeds 8000 mm. The simulation method can direct-viewing describe pulse-jet flow, and reflect accurately the characteristics of cleaning, thus enhance design reliability.
Effects of at-home and in-office bleaching agents on the shear bond strength of metal, ceramic, and composite brackets to enamel

Aims and Objectives: This study aimed to evaluate the effects of at-home and in-office bleaching on the shear bond strength (SBS) of metal, ceramic, and composite orthodontic brackets and to compare their SBSs. Subjects and Methods: A total of 96 human lower premolar teeth were used for this study. Six teeth were used for scanning electron microscopic study while the remaining ninety were divided into three equal groups. Each group was further subdivided into three subgroups with ten samples each. Three protocols were used. In the at-home bleaching group (n = 30), opalescence non-PF (potassium nitrate and fluoride) bleaching agent (10% carbamide peroxide) was applied onto the teeth daily for 14 days and left for 8 h each day. Teeth in the in-office group (n = 30) were treated twice in consecutive days with Opalescence boost PF (40% hydrogen peroxide). After bleaching, the specimens were stored in distilled water for 1 day before bonding. SBS testing was performed on all teeth using Instron universal testing machine. Results: Analysis of variance indicated a significant difference (P < 0.005) among the groups. Maximum SBS was shown by ceramic brackets in control group (Ib) and minimum was shown by composite brackets of in-office bleached group (IIIc). Conclusions: The results showed that at-home bleaching did not affect the SBS significantly whereas in-office bleaching reduced SBS of metal, ceramic, and composite brackets significantly. It is preferable to use metal or ceramic brackets than composite brackets for bonding 24 h after bleaching.
Bone Formation by Revascularized Periosteal and Bone Grafts, Compared With Traditional Bone Grafts

Three groups of dogs were studied to compare the bone formation obtained with traditional bone grafting techniques, and that obtained with revascularized periosteum or revascularized bone grafts—all in unstressed bone. Revascularized periosteum did not produce a significant amount of bone in this unstressed model. At 4 months the revascularized rib grafts had a slightly greater tolerance to stress at the callus site than traditional bone grafts, but the incidence of nonunion was the same. We conclude that the use of revascularized bone grafts should be reserved for situations in which traditional bone grafting techniques are unlikely to be successful.
Circulating vascular cell adhesion molecule-1 correlates with the extent of human atherosclerosis in contrast to circulating intercellular adhesion molecule-1, E-selectin, P-selectin, and thrombomodulin.

Secondary prevention of atherosclerosis, especially before the onset of symptoms, appears desirable and could be possible with a serum marker detecting atherosclerosis. Circulating, shedded forms of adhesion molecules may serve as such because their expression is upregulated in atherosclerotic plaques. In 52 patients with peripheral arterial vascular disease (Fontaine class IIa, 7 patients; class IIb, 29 patients; and class III, 16 patients), the extent of atherosclerosis was evaluated on the basis of angiograms of a large portion of the arterial system. The area diseased by atherosclerosis was determined by the percentage of vessel wall irregularities of the following calculated segments: aorta (distal from the kidney arteries), common iliac artery, external iliac artery, common femoral artery, lateral circumflex femoral artery, and popliteal artery. The maximal surface area that could exhibit atherosclerotic changes was 250 cm2. The serum concentration of circulating vascular cell adhesion molecule-1 (VCAM-1) correlated with the extent of atherosclerosis (r = .8, P < .001). In contrast, circulating intercellular adhesion molecule-1, E-selectin, P-selectin, and thrombomodulin (as markers for endothelial cell damage) did not correlate with the extent of atherosclerosis. Furthermore, circulating VCAM-1 could be used to indicate stages of atherosclerosis with a high degree of statistical significance. The potential bias of factors such as age, diabetes mellitus, hypercholesterolemia, arterial hypertension, renal failure, and history of myocardial infarction on the correlation of circulating VCAM-1 with the extent of atherosclerosis could be excluded by multivariate analysis. These findings suggest an important role of VCAM-1 in atherosclerosis and may serve as the basis for further evaluation of circulating VCAM-1 as a potential serum marker for atherosclerosis.
Clonal stability and phenotypic expression of chick cartilage cells in vitro.

presence of a metachromatic extracellular capsule, often most abundant toward the center of the colony; (2) autoradiographic demonstration of S'504- incorporation; (3) in combination with the above criteria, characteristic cellular and colonial morphology (Fig. 1A). Non-CMC's were distinguished by their fibroblastlike growth pattern and their lack of metachromasy or demon- strable sulfate incorporation. Plates were counted at magnifications of 10-30X.
UGA can be decoded as tryptophan at low efficiency in Bacillus subtilis

Replacement of cat-86 codon 7 or 144 with the UGA codon permitted the gene to confer chloramphenicol resistance in wild-type Bacillus subtilis. UAA replacements of the same codons resulted in a chloramphenicol-sensitive phenotype in wild-type B. subtilis and a chloramphenicol-resistant phenotype in suppressor-positive strains. N-terminal sequencing showed that UGA at codon 7 was decoded as tryptophan in wild-type cells, at an efficiency of about 6%.

Age-related effects of TGF-beta on proteoglycan synthesis in equine articular cartilage.

The synthesis of proteoglycans was measured in normal equine articular cartilage of ages 9 months to 20 years and the effect of TGF-beta1 on this activity was investigated. The rate of incorporation of [(35)S]Na(2)SO(4) decreased with age as did the responsiveness of the tissue to the growth factor. The enhanced synthesis of proteoglycan induced at all ages by TGF-beta1 was down-regulated by IL-1 beta and retinoic acid. The expression of mRNA for TGF-beta1, 2, and 3 was also measured, and although the level of TGF-beta1 was highest at all ages, the expression of each growth factor decreased with age.
Karyotype and male meiosis in Spartocera batatas and meiotic behaviour of multiple sex chromosomes in Coreidae (Heteroptera)

The Coreidae (Heteroptera) have holokinetic chromosomes and during male meiosis the autosomal bivalents segregate reductionally at anaphase I while the sex chromosomes do so equationally. The modal diploid chromosome number of the family is 2n = 21, with a pair of m-chromosomes and an X0/XX sex chromosome system. A 2n = 24/26 (male/female) and an X1X20/X1X1X2X2 sex chromosome system were found in Spartocera batatas (Fabricius). C-banding and fluorescent-banding revealed the presence of AT-rich heterochromatic bands medially located on all the autosomes, and one telomeric band on both the X1 and X2 chromosomes. This banding pattern differed from the telomeric heterochromatin distribution found in most other heterop- teran species. The X1 and X2 chromosomes were intimately associated during male meiosis and difficult to recognize as two separate entities. Based on a comparison with the behaviour of sex chromosomes in other coreids and other heteopterans with multiple sex chromosomes it is suggested that the particular behaviour of X1 and X2 chromosomes in coreid species with multiple sex chromo- some systems evolved as an alternative mechanism for ensuring the proper segregation of the sex chromosomes during meiosis.
Antimicrobial Resistance Genes in Enterotoxigenic Escherichia coli O149:K91 Isolates Obtained over a 23-Year Period from Pigs

ABSTRACT A total of 112 Escherichia coli O149:K91 strains isolated from pigs with diarrhea in Quebec, Canada, between 1978 and 2000 were characterized for their genotypic antimicrobial resistance profiles. Tests for resistance to 10 antimicrobial agents were conducted. Resistance to tetracycline and sulfonamides was found to be the most frequent, but resistance to cefotaxime and ceftiofur was absent. An increase in the number of isolates resistant to at least three antimicrobials was observed over time. The distribution of 28 resistance genes covering six antimicrobial families (beta-lactams, aminoglycosides, phenicols, tetracycline, trimethoprim, and sulfonamides) was assessed by colony hybridization. Significant differences in the distributions of tetracycline [tet(A), tet(B), tet(C)], trimethoprim (dhfrI, dhfrV, dhfrXIII), and sulfonamide (sulI, sulII) resistance genes were observed during the study period (1978 to 2000). Sixty percent of the isolates possessed a class 1 integron, illustrating the importance of integrons in the epidemiology of antibiotic resistance in E. coli strains from pigs. Amplification of the integron's variable region resulted in four distinct fragments of 1, 1.3, 1.6, and 1.8 kb, with the 1.6- and 1.8-kb fragments appearing only during the last half of the study period. Examination of linkages among the different resistance genes showed a variety of positive and negative associations. Association analysis of isolates divided into two groups, those isolated between 1978 and 1989 and those isolated between 1990 and 2000, revealed the appearance of new positive resistance gene associations. Our genotypic resistance analyses of ETEC isolates from pigs indicate that many of the antibiotic resistance genes behind phenotypic resistance are not static but, rather, are in a state of flux driven by various selection forces such as the use of specific antimicrobials.
Knowledge and perceptions of sport psychology within English soccer

The aim of the present study was to examine knowledge and perceptions of applied sport psychology within English soccer. National coaches (n = 8), youth academy directors (n = 21) and academy coaches (n = 27) were surveyed using questionnaire and interview methods. Questionnaire results revealed a lack of knowledge of sport psychology that appeared to underpin some of the most significant barriers to entry for sport psychologists. These included lack of clarity concerning the services of a sport psychologist, problems fitting in and players' negative perceptions of sport psychology. Overall, however, lack of finance was the highest rated barrier. Six barrier dimensions emerged from the interview data: negative perceptions of psychology, lack of sport psychology knowledge, integrating with players and coaching staff, role and service clarity, practical constraints, and perceived value of sport psychology. These findings were broadly compatible with the survey data, with finance emerging as a major barrier and misconceptions of sport psychology being common. Our conclusions are discussed in relation to the practical implications of the study for both applied research and the provision of sport psychology services within English soccer.
Pharmacotherapy to protect ovarian function and fertility during cancer treatment

In recent years, modern anticancer treatments have led to significant survival improvements; however, in premenopausal women, the administration of these therapies is also associated with potential unwanted side effects such as treatment-related premature ovarian failure (POF) and subsequent reduced fertility [1]. At the time of cancer diagnosis, the maintenance of gonadal function and fertility has crucial importance for many patients. As recommended by international guidelines, all patients of reproductive age should be counseled about the potential treatment-related loss of ovarian function and fertility and helped with informed fertility preservation decisions [2,3]. For young female cancer patients, embryo/oocyte cryopreservation are standard strategies to preserve fertility [2,3]; however, they require a period of controlled ovarian stimulation with subsequent delay in the initiation of anticancer treatments and they cannot preserve gonadal function during cytotoxic therapy. Pharmacological protection of the ovaries with the use of temporary ovarian suppression with gonadotropin-releasing hormone analogs (GnRHa) during chemotherapy is a widely available option requiring no delay in the initiation of treatment. However, taking into account the controversial data available up to 2013, it was considered an experimental strategy in cancer patients [2,3]. Over the past few years, several important news have become available on the potential efficacy and safety of temporary ovarian suppression with GnRHa during chemotherapy as a strategy to preserve ovarian function and fertility in young patients with breast cancer and lymphoma.
The Incidence of Myelofibrosis in Essential Thrombocythaemia, Polycythaemia vera and Chronic Idiopathic Myelofibrosis: A Retrospective Evaluation of Sequential Bone Marrow Biopsies

The incidence of myelofibrosis (MF) among the three major Philadelphia chromosome-negative chronic myeloproliferative disorders, i.e. essential thrombocythaemia (ET), polycythaemia vera (PV) and chronic idiopathic myelofibrosis (CIMF), is not well documented since the diagnostic criteria have recently been redefined by the WHO. Therefore we performed a retrospective analysis of follow-up biopsies of 275 patients with ET, PV and CIMF according to the WHO classification of chronic myeloproliferative disorders. In the diagnostic bone marrow biopsies, MF was observed in 57 of the 136 CIMF patients (42%), 4 of the 73 PV patients (5%) and none of the 66 patients with ET. Within a median observation time of 2.9 years, 34 of the 79 patients with CIMF (43%), 13 of the 69 patients with PV (19%) and 1 of the 66 patients with ET (1.5%) – each initially without MF – developed MF regardless of myelosuppressive therapy.
EFFECTS OF ORGANIC ACID AND PLANT OILS ON SHEEP RUMEN FATTY ACID COMPOSITION

The effects of diets (i.e., high fibre, HF and high concentrate, HC) supplemented with either fumaric acid (FUM; 8 mmol/L) or maleic acid (MAL; 8 mmol/L) and different plant oils (35.0 g/kg dry matter; sunflower, SO; rapeseed, RO; and linseed, LO) on rumen sheep fatty acids (FA) concentration and biohydrogenation (BH) in batch cultures were examined. The oils rich in linoleic acid (SO, 535 g/kg of FA), oleic acid (RO, 539 g/kg of FA) and α-linolenic acid (LO, 538 g/kg of FA) were examined. The diets and organic acids with oils (AO) affected the concentration of almost all FA in batch cultures. Compared with the control, higher concentrations of trans-vaccenic acid occurred for the HF-diet with FUM+SO and MAL+SO (P<0.001) and for HC-diet with FUM+SO, MAL+SO, FUM+RO and MAL+RO (P<0.01 and P<0.001). The BH of oleic acid in both the HFand HC-diets with organic acids and oils was decreased when compared with the control. The combination of FUM and MAL, especially with SO and RO, might positively enhance the concentration of FA and some FA intermediates and decreases the BH of C18 FA in rumen fluid in batch cultures.
