Dyadic Speech-based Affect Recognition using DAMI-P2C Parent-child Multimodal Interaction Dataset

Automatic speech-based affect recognition of individuals in dyadic conversation is a challenging task, in part because of its heavy reliance on manual pre-processing. Traditional approaches frequently require hand-crafted speech features and segmentation of speaker turns. In this work, we design end-to-end deep learning methods to recognize each person's affective expression in an audio stream with two speakers, automatically discovering features and time regions relevant to the target speaker's affect. We integrate a local attention mechanism into the end-to-end architecture and compare the performance of three attention implementations - one mean pooling and two weighted pooling methods. Our results show that the proposed weighted-pooling attention solutions are able to learn to focus on the regions containing target speaker's affective information and successfully extract the individual's valence and arousal intensity. Here we introduce and use a "dyadic affect in multimodal interaction - parent to child" (DAMI-P2C) dataset collected in a study of 34 families, where a parent and a child (3-7 years old) engage in reading storybooks together. In contrast to existing public datasets for affect recognition, each instance for both speakers in the DAMI-P2C dataset is annotated for the perceived affect by three labelers. To encourage more research on the challenging task of multi-speaker affect sensing, we make the annotated DAMI-P2C dataset publicly available, including acoustic features of the dyads' raw audios, affect annotations, and a diverse set of developmental, social, and demographic profiles of each dyad.
Detecting and Repairing Arbitrage in Traded Option Prices

ABSTRACT Option price data are used as inputs for model calibration, risk-neutral density estimation and many other financial applications. The presence of arbitrage in option price data can lead to poor performance or even failure of these tasks, making pre-processing of the data to eliminate arbitrage necessary. Most attention in the relevant literature has been devoted to arbitrage-free smoothing and filtering (i.e., removing) of data. In contrast to smoothing, which typically changes nearly all data, or filtering, which truncates data, we propose to repair data by only necessary and minimal changes. We formulate the data repair as a linear programming (LP) problem, where the no-arbitrage relations are constraints, and the objective is to minimize prices’ changes within their bid and ask price bounds. Through empirical studies, we show that the proposed arbitrage repair method gives sparse perturbations on data, and is fast when applied to real-world large-scale problems due to the LP formulation. In addition, we show that removing arbitrage from prices data by our repair method can improve model calibration with enhanced robustness and reduced calibration error.
Coordination of Overcurrent Protection and Fault Ride through Requirements of Doubly Fed Induction Generator in a Wind Turbine

Due to power system stability in high penetration of wind turbines during grid disturbances, the Fault Ride Though (FRT) requirements have been developed to remain connected the wind turbines during the grid voltage sags. Usually the FRT requirements are implemented with crowbar protection that protects the rotor side converter, but the generator windings have noticeable over current during grid voltage disturbances. Therefore, the stator current of doubly fed induction generator is investigated in grid voltage sags, and then the overcurrent settings of stator winding are analyzed. Main focus of this paper is coordination of overcurrent protection with FRT requirements. The overcurrent curves and time settings are discussed in agreement with FRT requirements.
Pollenernte und Massenwechsel von drei Apis mellifera-Völkern auf demselben Bienenstand in zwei aufeinanderfogenden Jahren

Pollen gathering and population dynamics of three Liebefeld bee colonies of Apis mellifera during two consecutive years. —The amounts of pollen gathered varied from 10 to 26 kg per colony and year. 189 different pollen types were identified. The 40 major pollen types formed more than 90% of the total pollen collected. Zea mays, Brassica sp. , Acer sp. , Plantago lanceolata, Taraxacum officinale and Salix sp. contributed 51% of the total pollen harvest. There were great quantitative and qualitative differences between the pollen types gathered, which must be due to individual preferences. Wecould, however, not demonstrate that one colony or the other preferred uncommon pollen types. 99 of the major pollen types gathered in Switzerland by Apis mellifera were submitted to measurements of the amino acid contents and spectrum. The total amino acid contents varied from 5% of dry weight for Pinus sp. and Cupressaceae to 33% for Sarothanuius scoparius. There was no predilection for pollen types with high amino acid content. There was a close correlation between most essential amino acid levels and the total amino acid content: 44% of the measured amino acids were essential ones. Only for Hist idine, arginine and methionine this relationship was less evident. If the pollen provisions are of mixed origin, there is hardly a risk of unbalanced amino acid supply. Analysis of * Sektion Bienen, FAM, 3097 Liebefeld, Schweiz. 1 Poster präsentiert an der Jahresversammlung der SSZ in Genf, 1. -2. Mar/ 198 898 H. WILLE, M. WILLE, V. KILCHENMANN,A. IMDORF, G. BÜHLMANN population dynamics resulted into great differences in the number of bees, brood surfaces and fluctuations of these parameters. However, the ratio "bee days/reared brood cell" was rather constant, i.e. 19 days per colony and year. The correlations between pollen quantity gathered, number of reared brood cells, number of bee days and life expectancy were loose.
The Biochemical Characterization Of Neuronal K+ Channel N-Glycans And Their Role In Regulating K+ Channel Function

The Kv3 and Kv1 subfamilies of voltage–gated K+ channels are critical components which contribute to action potential repolarization throughout the central nervous system. Here, it was shown that both absolutely conserved N–glycosylation sites of the Kv3.1, Kv3.3 and Kv3.4 proteins were occupied in the central nervous system of the adult rat by complex oligosaccharides. Additionally, it was demonstrated that the expression patterns of the Kv3 glycoproteins were different from one another throughout the central nervous system. Electrophoretic migration patterns of the Kv3 glycoproteins from different membranes of the central nervous system digested with glycosidases were utilized to identify the attachment of unique sialylated N–glycan structures. An examination of these sialylated N–glycan structures revealed that the Kv3 glycoproteins, along with the Kv1.1, Kv1.2, and Kv1.4 glycoproteins, were terminated with atypical disialyl units. Moreover, at least one of the carbohydrate chains of the Kv3.1, Kv3.3 and Kv3.4 glycoproteins, like Kv3.1 heterologously expressed in B35 cells, was capped with an oligo/polysialic acid unit. Notably, this is the first time that di/oligo/polysialyl units have been shown to be associated with K+ channels. Sialyl residues linked to internal carbohydrate residues were shown to be components of the N–glycans of the Kv1 glycoproteins, as well as the Kv3 glycoproteins and N–CAM. To date, this unusual glycosidic bond for sialyl residues has not been identified on N–glycans. Whole cell current measurements of glycosylated (wild type), unglycosylated mutant (N220Q/N229Q) and partially glycosylated mutant (N220Q and N229Q) Kv3.1 channels heterologously expressed in B35 cells revealed that the glycosylated Kv3.1 protein could favor a subpopulation of channels with fast activation and inactivation rates for inactivating currents. However, this subpopulation was undetectable for the inactivating currents of the unglycosylated and partially glycosylated Kv3.1 channels. Additionally, the noninactivating current type of the glycosylated and partially glycosylated Kv3.1 channels revealed a subpopulation of Kv3.1 channels with fast activation and inactivation rates, as well as with fast activation and slow inactivation. We conclude that the presence of atypical sialylated N–glycans of Kv3 glycoproteins, and perhaps Kv1 glycoproteins, in mammalian brain is critical in modulating the expression of K+ currents at the surface of neurons.
Studies of amylase from crystalline style of short-necked clam. I. Purification and properties of amylase.

An α-amylase was isolated from the crude extract of the crystalline-style of short-necked clam, Ruditapes philippinarum, by a combination of gel filtration on Sephadex G-50, Bio-Gel P-10, and Sephadex G-25 in the presence of strontium chloride. The specific activity was increased about 370-fold from the crude extract with high recovery. The enzyme was found to be homogeneous by polyacrylamide gel disc-electrophoresis. The enzyme gave an absorption spectrum which exhibited the maximum at 278nm and minimum at 250nm; the extinction coefficient, E1%1cm value at 280nm was 5.97. Optimum pH of the enzyme for soluble starch was found to be 6.2, and the maximum activity was found at 36°C on 20min incubation. The enzyme was relatively stable at pH values higher than 6.0, but was completely inactivated by heating at 55°C for 10min at pH 6.5. The enzyme was activated with chlorides of metals such as sodium, strontium, calcium, and magnesium; the highest activity was observed in the presence of 0.025M strontium chloride. The enzyme was protected from denaturation by strontium chloride when the enzyme was stored without freezing. But the enzyme was labile to freezing.
Spore Age and Sterilization Affects Germination and Early Gametophyte Development of Platycerium bifurcatum

The effects of spore age and sterilization on spore germination and early gametophyte development were investigated in the fern, Platycerium bifurcatum. The highest germination per- centage of sterilized spores was obtained with 2-3 month old spores. Further increase in spore age leads to a decline in germination and primary rhizoid initiation. In contrast, spore age had no effect on the germination of unsterilized spores, where maximum response was observed with spores of both storage periods tested, 2 and 14 months. Increasing spore age delays early game- tophyte development. In cultures of sterilized spores, this was evident from both a decrease in the length of the primary rhizoid and the decreased number of rhizoids and cells per gametophyte. Although longer primary rhizoids developed from unsterilized spores of both ages, after 10 days other growth parameters of gametophytes were similar or even lower compared to those from sterilized spores.
APACE: accelerated permutation inference for the ACE model

Introduction Heritability studies of imaging phenotypes are becoming more commonplace. Heritability, the proportion of phenotypic variance attributable to genetic sources, is typically estimated with variance components model (e.g. in SOLAR) or structural equation models (e.g. in OpenMx), but these approaches are computationally expensive and cannot exploit the sensitivity of the spatial statistics, like clusterwise tests. Thus, we developed a non-iterative estimation method for the ACE model; this method is accurate [1] and is so fast that it allows the use of permutation, which provides sensitive family-wise error (FWE) corrected voxeland cluster-wise inferences [1].
Influences of Time Postmortem, Feeding Activity, and Diet on Digestive Organ Morphology of Two Emberizids

-We conducted experiments to determine the effect of time postmortem, feeding activity, and diet on changes in digestive organ morphology in Dark-eyed Juncos (Junco hyemalis) and Harris' Sparrows (Zonotrichia querula). We measured digestive organs immediately, or at 30, 60, or 90 min postmortem, but detected no time-related differences in Darkeyed Juncos. The small intestines of free-feeding Dark-eyed Juncos were longer than those of food-deprived birds. We found no significant diet-related differences in lengths of small intestines of Harris' Sparrows. Liver mass reflected energy intake of free-feeding versus fooddeprived Harris' Sparrows. Received 4 August 1989, accepted 7 April 1990. THE AVIAN literature abounds with descriptions of changes in digestive organ morphology. Researchers attributed changes in avian gizzard size to the texture and fiber content of the diet (Ziswiler and Farner 1972, Savory and Gentle 1976a, Kehoe and Ankney 1985), and reported a relationship between gizzard mass and body mass in northern Galliformes (Thomas 1984, Moss 1983). Leopold (1953) and Kehoe and Ankney (1985) suggested that a high-fiber diet causes increased lengths of small intestines, a conclusion reached by several researchers working on tetraonids (Moss 1974, Pendergast and Boag 1973, Pulliainen and Tunkkari 1983). A causal relationship between cecal size and dietary fiber was proposed (Leopold 1953) and supported with experimental evidence (Moss 1972, 1989; Savory and Gentle 1976b; Moss and Trenholm 1987; but see Remington 1989). Ziswiler and Farner (1972) contended that largeintestine length reflects the diet of avian species, and Savory and Gentle (1976a, b) could produce increases in large-intestine length by adding fiber to the diet of Japanese Quail (Coturnix coturnix). Most pertinent reports on avian species have involved gallinaceous birds and waterfowl. Little attention has been focused on changes in gut morphology of passerines, or the influence of time postmortem or feeding activity on measurements of gut morphology. In this study, we examined the effects of time postmortem, feeding activity, and diet on digestive organ morphology of two emberizids, Harris' Sparrow (Zonotrichia querula) and the Dark-eyed Junco (Junco hyemalis).
Utilisation de la 13-Hydroperoxyde lyase recombinante d’olive dans des procédés biocatalytiques de production de composés à note verte

L’hydroperoxyde lyase (HPL) est une enzyme issue de la voie de la lipoxygenase, voie metabolique tres representee chez les vegetaux, impliquee dans la production de composes aromatisants (l’hexanal, le 3Z-hexenal et le 2E-hexenal). Ces composes sont responsables de l’odeur fraiche de l’herbe coupee dite « note verte » et sont tres utilises par les industries cosmetiques et agroalimentaires. Leur biosynthese resulte de l’oxydation des acides gras polyinsatures en hydroperoxydes par la lipoxygenase, puis de leur clivage par l’hydroperoxyde lyase (HPL). Les procedes actuels de production de ces composes presentent certains inconvenients, ils sont notamment tres polluants et peu performants, aussi l’utilisation d’enzymes recombinantes dans de tels procedes permettrait d’obtenir ces molecules de maniere plus efficace tout en beneficiant du label "naturel". L’ADNc codant pour l’hydroperoxyde lyase (HPLwt) a ete isole au laboratoire a partir d’olives noires. Afin d’ameliorer la solubilite de l’enzyme, une HPL depourvue de son peptide de transit chloroplastique (HPLdel) a egalement ete produite. Les deux enzymes ont ete exprimees chez E.coli, purifiees par chromatographie d’affinite puis caracterisees biochimiquement. Elles agissent exclusivement sur les 13-hydroperoxydes (13-HPL) a un pH et une temperature optimum de 7,5 et 25°C. De plus l’evaluation des parametres cinetiques de l’enzyme montre qu’elles ont une meilleure efficacite catalytique (kcat/Km) sur les 13-hydroperoxydes d’acide linolenique (3,68 s-1.µM-1) que sur les 13-hydroperoxydes d’acide linoleique (0,54 s-1.µM-1). La bioconversion des 13-hydroperoxydes d’acide linoleique et linolenique en hexanal et 3Z-hexenal par l’action de l’HPLwt et l’HPLdel a ete etudiee. Des taux de conversion maximum atteignant 93 % et 68 % pour la production d’hexanal et 73 % et 45% pour la production d’3Z-hexenal ont ete obtenus quand l’HPLwt et l’HPLdel sont utilisees respectivement. La stabilite de l’enzyme a ensuite ete etudiee. Des essais de conservation montrent que l’utilisation de glycerol a 10% (v/v) permet le maintien de la totalite de l’activite de l’HPLwt et de l’HPLdel durant cinq semaines de stockage a -80°C. De plus, l’ajout de composes chimiques tels que le KCl, le NaCl, le Na2SO4, la glycine et le glycerol permettent d’augmenter l’activite enzymatique des deux enzymes et d’ameliorer les conditions de synthese de l’hexanal et du 3Z-hexenal en diminuant la quantite d’enzyme necessaire a leur production.
Efficacy of HVT-IBDV Vector Vaccine Against Recent Egyptian vvIBDV in Commercial Broiler Chickens

The efficacy of a turkey herpesvirus (HVT-IBD) vector vaccine encoding the VP2 gene of Infectious Bursal Disease (IBD) was evaluated in comparison with classic vaccines on two commercial broiler chicken farms (A and B), with high levels of Maternal Derived Antibodies (MDA). The HVT-IBD vaccine was administrated into chickens of farm A at 1-day-old while intermediate and intermediate-plus vaccines were given at 1-and 14-day-old into chickens of farm B, respectively. An early significant seroconversion was detected at 21-day-old in chickens of farm A, while no significant serological response was detected in farm B at this time. The antibody level was significantly higher in chickens in farm A at 28-and 35-day-old. Moreover, HVT-IBD vaccine provided complete protection against recent Egyptian vvIBDV isolate. In conclusion, HVT-IBD vaccine has the ability to induce an immune response in birds with high levels of MDA and could protect against recent Egyptian vvIBDV isolates.
Proteomic Analysis of Candidate Prognostic Urinary Marker for Cervical Cancer

Urinary proteins are an important component in urine samples that can be used as biological indicators for clinical diagnosis of diseases, such as proteinuria, kidney failure, diseases in the bladder, urinary tract and related organs. In this present work, we investigated candidate protein biomarkers in urine for diagnosis of cervical cancer using proteomic approach. The urine samples were concentrated and de-salted through ultrafiltration (3 kDa), followed by Spin-50 mini-sephadex column and were then separated by two-dimensional electrophoresis (2-DE) and annotated by mass spectrometer. Comparing 2-DE results between individual healthy donors and cervical cancer, patients showed that 4 urinary proteins; Protocadherin-8, Aryl hydrocarbon receptor nuclear translocatorlike protein 2, Serum albumin and Endorepellin, C-terminal domain V of perlecan were overexpressed by two-fold in the patient samples. Only the endorepellin LG3 fragment was validated by Western blot analysis. We also used 2D Western blot and nano LC-MS/MS to confirm the urinary biomarker as endorepellin LG3 fragment. Our study suggests that proteomics approach may be useful for the study of urinary proteins and provides an opportunity to discovery aberrant protein-associated diseases. We also revealed the candidate biomarkers that may be applied for cervical cancer diagnosis which benefits for medical treatment.
Structure and Production of North Pennine Blanket Bog Vegetation

Moor House National Nature Reserve, on the North Pennines in the north-east corner of Westmorland, is the main British moorland site for the International Biological Programme (IBP) productivity studies. The present work forms part of an integrated research programme designed to study the dynamics of the entire bog ecosystem, in particular the cycling of dry matter within the community. It is important that reliable estimates of the primary production of the ecosystem, which forms the starting material for conversions involving secondary producers, decomposers and peat formation, should be obtained. The vegetation of the reserve consists predominantly of Calluneto-Eriophoretum blanket bog (Eddy, Welch & Rawes 1969). To estimate the production of such a dwarf shrub-tussock community, it is insufficient merely to measure biomass increments through the season; additional methods, relying upon an adequate quantitative description of the community structure, have had to be developed, some of which are similar to those commonly used in woodland production studies. The fieldwork comprising the main part of this project was carried out in 1968, although sampling of Calluna litterfall and of Eriophorum tussocks was continued into 1969.
Unipolar injection currents in Bi4Ge3O12 crystals

Current-voltage characteristics of bismuth orthogermanate (Bi4Ge3O12) single crystals have been measured at different temperatures under conditions of unipolar injection of charge carriers. It has been found that conduction is characterized by the existence of two channels of the percolation. The temperature dependencies of the conductivity, mobility and concentration of the electrons and holes are considered. The obtained results are discussed in terms of hopping transport model of charge carriers in doped heavily compensated semiconductors.
Influence of Climatic Conditions and Elevation on the Spatial Distribution and Abundance of Trypodendron ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae) in Alaska

The objective of this study was to model the influence of temperature and precipitation on the distribution and abundance of the ambrosia beetles in the genus Trypodendron. Although these beetles do not attack and kill healthy trees, their gallery holes and accompanying black and gray stain associated with symbiotic ambrosial fungi can cause significant economic losses to commercial logs and wood products. Beetles were collected along a 1,100-km latitudinal transect 4 times at 2-week intervals at 43 sites beginning early July using Lindgren-funnel traps baited with ethanol, alpha-pinene, and lineatin. Average annual temperature and precipitation were used to partition the state into 25 climatic zones. Large-scale patterns of beetle distribution were correlated with elevation and the temperature and precipitation zones. Results indicate that reasonably accurate predictions of beetle abundance can be generated using models based on trap data collected across several climate zones. Predictions derived from this latitudinal transect can be extrapolated to more remote areas using species– environment relationships based on temperature and precipitation combinations. Partitioning large geographic areas using climatic zones offers a logical approach for predicting insect activity in remote areas, and if implemented on a long-term basis would be able to provide estimates of yearly and seasonal trends in the infestation. Such information would allow forest managers to evaluate the impact on forest ecosystem services and improve future assessments that predict the influence of a changing climate on insect pest migrations and their intensification during outbreaks.
Low formaldehyde emission particleboard bonded by UF-MDI mixture adhesive

Chinese wood-based composite manufacturers are plagued with serious formaldehyde emission (F-emission) problems. Most products release formaldehyde between 35 and 60 mg per 100 g board. In this study, a particleboard with an emulsifiable diphenylmethane-4,4'-diisocyanate (MDI) - urea-formaldehyde (UF) mixture adhesive was investigated in order to decrease F-emission to below 9 mg per 100 g board. Comparison of physical and mechanical properties of particleboard showed that the acidic agent NH 4 Cl did not improve the UF-MDI system curing, and it also affected the adhesive application method. When the two adhesives were mixed first, without adding NH 4 Cl, and then sprayed onto particles, properties were improved. Hot-press conditions that would optimize particleboard mechanical properties and ensure that F-emissions met E1 grade requirements were determined; hot-pressing at 175°C for 4.5 minutes might lower F-emissions to below 9 mg per 100 g particleboard.
