From expressive gesture to sound The development of an embodied mapping trajectory inside a musical interface

This paper contributes to the development of a multimodal, musical tool that extends the natural action range of the human body to communicate expressiveness into the virtual music domain. The core of this musical tool consists of a low cost, highly functional computational model developed upon the Max/MSP platform that (1) captures real-time movement of the human body into a 3D coordinate system on the basis of the orientation output of any type of inertial sensor system that is OSC-compatible, (2) extract low-level movement features that specify the amount of contraction/expansion as a measure of how a subject uses the surrounding space, (3) recognizes these movement features as being expressive gestures, and (4) creates a mapping trajectory between these expressive gestures and the sound synthesis process of adding harmonic related voices on an in origin monophonic voice. The concern for a user-oriented and intuitive mapping strategy was thereby of central importance. This was achieved by conducting an empirical experiment based on theoretical concepts from the embodied music cognition paradigm. Based on empirical evidence, this P. -J. Maes, M. Leman, M.

Continuity of vortices from the hadronic to the color-flavor locked phase in dense matter

We study how vortices in dense superfluid hadronic matter can connect to vortices in superfluid quark matter, as in rotating neutron stars, focusing on the extent to which quark-hadron continuity can be maintained. As we show, a singly quantized vortex in three-flavor symmetric hadronic matter can connect smoothly to a singly quantized non-Abelian vortex in three-flavor symmetric quark matter in the color-flavor locked (CFL) phase, without the necessity for boojums appearing at the transition. This smooth transition supports the possibility of quark-hadron continuity between the hadronic and quark phases at finite angular momentum. Although non-Abelian vortices appear to carry color flux, in a gauge invariant description of such vortices, as we construct, their color does not appear in physical observables.
The dining and tipping behaviour of Black South Africans: a segmentation approach

The literature on dining and tipping behaviour has focused mostly on the United States of America (USA), while minimal research has been conducted in African countries. While there is a negative and grounded perception surrounding black diners being poor tippers in the USA, hardly any research has focused on the dining or tipping behaviour of this dining market from a developing country perspective. The intention of this exploratory research was to fill the current knowledge gap by segmenting black South Africans on the basis of their motives for dining out and to determine the differences in the dining and tipping behaviour of the different segments. To target potential black diners, a visitor survey was conducted at the Cape Town International Jazz Festival. A total of 256 usable questionnaires were returned and included in the analysis. Socialisation, gastronomy enjoyment, lifestyle and escape and status were identified as the four motives for dining out. Based on these motives, different black dining segments were identified and an OSI (Occasionalists, Socialisers and Indulgers) typology of diners proposed. The dining and tipping behaviour of these dining segments are furthermore influenced by several factors, with clear implications for both the server and restaurateurs. The results shed light on the dining and tipping behaviour of black South African diners and showed that this dining market cannot be regarded as bad tippers.
Textual Metadiscourse Resources in Research Articles

This study was motivated by three factors, which also contribute to its significance for today’s academic writing. First, research articles are the significant means of communication between the writers all over the world. Second, persuasion and organization are crucial notions in academic writing where the authors have to consider the academic audiences and their needs. Third, some writers are not the native speakers of English and write their research articles in English. Despite their importance in academic writing, we know little about how textual metadiscourse resources (TMRs) are used in different disciplines and genres. This study examines the use of TMRs in research articles of three disciplines of Mechanical Engineering (ME), Medicine (MED), and Applied Linguistics (AL). It also explores distribution of TMRs by native and non-native writers of English in the research articles of three disciplines. Based on a corpus of thirty research articles, the frequency of TMRs was calculated per 1,000 words. The findings of the study indicate a significant difference in the distribution of TMRs in three disciplines and also between the writings of native and non-native writers. In addition, these findings may have some implications for teaching disciplinary communication especially to foreign language learners of English.
Radial variations in wood mineral element concentrations: a comparison of beech and pedunculate oak from the Belgian Ardennes

Les variations radiales des teneurs en elements mineraux (N, P, Ca, Mg, K, Mn, Al) ont ete mesurees dans 5 chenes (une essence a anneaux poreux et a bois de coeur bien differencie) et 5 hetres (une essence a porosite diffuse et depourvue de bois de coeur bien differencie) croissant sur sol brun ocreux dans le massif ardennais belge. Les differences dans les profils dendrochimiques sont conformes aux differences structurales du bois. Chez le chene, les concentrations sont nettement plus elevees dans l'aubier, ce qui suggere une resorption active des elements mineraux au cours du vieillissement des cernes, avec pour consequence des concentrations extremement faibles dans le bois de cœur. Des convergences entre les deux especes - notamment une apparente diminution des concentrations en cations (dans le bois de coeur pour le chene, tout au long de la chronologie pour le hetre) accompagnee d'une augmentation recente des teneurs en aluminium -- pourraient etre attribuees a une influence environnementale commune, par exemple une denaturation du sol sous l'influence de pluies acides. Cependant, la diminution des teneurs en manganese enregistree chez les deux essences ne conforte pas l'hypothese d'une acidification du sol. D'autres hypotheses sont discutees.
Heat storage in forest biomass improves energy balance closure

Abstract. Temperature measurements in trunks and branches in a mature ca. 100 years-old mixed pine and spruce forest in central Sweden were used to estimate the heat storage in the tree biomass. The estimated heat flux in the sample trees and data on biomass distributions were used to scale up to stand level biomass heat fluxes. The rate of change of sensible and latent heat storage in the air layer below the level of the flux measurements was estimated from air temperature and humidity profile measurements and soil heat flux was estimated from heat flux plates and soil temperature measurements. The fluxes of sensible and latent heat from the forest were measured with an eddy covariance system in a tower. The analysis was made for a two-month period in summer of 1995. The tree biomass heat flux was the largest of the estimated storage components and varied between 40 and −35 W m−2 on summer days with nice weather. Averaged over two months the diurnal maximum of total heat storage was 45 W m−2 and the minimum was −35 W m−2. The soil heat flux and the sensible heat storage in air were out of phase with the biomass flux and they reached maximum values that were about 75% of the maximum of the tree biomass heat storage. The energy balance closure improved significantly when the total heat storage was added to the turbulent fluxes. The slope of a regression line with sum of fluxes and storage as independent and net radiation as dependent variable, increased from 0.86 to 0.95 for half-hourly data and the scatter was also reduced. The most significant finding was, however, that during nights with strongly stable conditions when the sensible heat flux dropped to nearly zero, the total storage matched the net radiation very well. Another interesting result was that the mean energy imbalance started to increase when the Richardson number became more negative than ca. −0.1. In fact, the largest energy deficit occurred at maximum instability. Our conclusion is that eddy covariance measurements can function well during stable conditions but that the functioning under strong instabilities might be a so far unforeseen problem.
Research article ASSESSMENT OF TRACE HEAVY METALS CONTENTS OF CHICKEN FROM ALGERIA

Due to the consumption of chicken and chicken products(kidney, liver and meat) in Algeria at high ratio, The concentration of some heavy metals (Pb, Cd and Hg) content in chicken and chicken products collected from three major industrial and urban cities (Algiers, Bejaia, and Tizi ouzou) in Algeria were determined used atomic absorption spectrometry after acid digestion. The obtained results showed that the concentrations of the studied metals were under the recommended maximum acceptable levels proposed by the Joint FAO/WHO expert Committees. The levels of lead in some analyzed chicken products were higher than the recommended legal limits for human consumption. Trace element content in various parts of chicken samples and chicken products were to be found in kidney within the range of 42.05-122ug/Kg for mercury, from 17.77-19.55ug/kg for cadmium, and for 70.34-141.45g/Kg for lead. In liver within the range of 28.82-115ug/Kg for mercury, from 5.45-11.79 ug/kg for cadmium, and 103.85-128.56 ug/Kg for lead. In meat within the range of 25.5-99.11ug/Kg for mercury, from 4.69-10.53ug/kg for cadmium, and from 83.44-109.82ug/Kg for lead.
Understanding the Self-Prophecy Phenomenon

The self-prophecy effect suggests that asking people to predict whether or not they will perform a target action leads to increased probability of performing that action, often in a socially normative direction. In two experiments, competing theories of cognitive dissonance and social identity activation were explored. Experiment 1 revealed that, following an experimentally manipulated prediction request, subjects’ self-identity with a target behavior (recycling) and self-esteem increased relative to a control group. In Experiment 2, self-esteem was manipulated, followed by a prediction request. Results suggested that self-prophecy effects may be the result of the activation of normative social identities.
Effect of Pin Shapes on Joint Characteristics of Friction Stir Spot Welded AA5J32 Sheet

The joint strength of friction stir spot welded 5J32 Al alloy was investigated according to the tool shape (threaded pin tool: TPT; cylindrical tool: CT; cylindrical tool with projection: CTP) and tool penetration depth. With increasing tool penetration depth, the vertical joint deformation increased in TPT and CT, whereas the joint diameter increased in TPT. The tensile shear load of the joint using TPT and CT did not vary with tool penetration depth, because the decreased upper plate thickness impeded the increase of the tensile shear load. That of CTP, however, rapidly increased with increasing tool penetration depth to produce a maximum tensile shear load of 4.6 kN. CTP, with its shoulder comprising a slight, broad projection, retarded the vertical joint deformation and produced good mechanical properties.
FACULTY OF INFORMATICS GRADUATE PROGRAM IN COMPUTER SCIENCE MASTER IN COMPUTER SCIENCE ALAN DIEGO DOS SANTOS RANKING LIGANDS IN STRUCTURE-BASED VIRTUAL SCREENING USING SIAMESE NEURAL NETWORKS Porto Alegre

Structure-based virtual screening (SBVS) on compounds databases has been widely applied in early stage of the drug discovery on drug target with known 3D structure. In SBVS, computational approaches usually ’dock’ small molecules into binding site of drug target and ’score’ their binding affinity. However, the costs involved in applying docking algorithms into huge compounds databases are prohibitive, due to the computational resources required by this operation. In this context, different types of machine learning strategies can be applied to rank ligands, based on binding affinity, and to reduce the number of compounds to be tested. In this work, we propose a deep learning energy-based model using siamese neural networks to rank ligands. This model takes as inputs grids of biochemical properties of ligands and receptors and calculates their compatibility. We show that the model can learn to identify important biochemical interactions between ligands and receptors. Besides, we demonstrate that the compatibility score is computed based only on conformation of small molecule, independent of its position and orientation in relation to the receptor. The proposed model was trained using known ligands and decoys in a Fully Flexible Receptor model of InhA-NADH complex (PDB ID: 1ENY), having achieved outstanding results.
Detection of Breakpoints in Volatility

In this article, we test for the presence of structural breaks in volatility by two alternative approaches: the Iterative Cumulative Sum of Squares (ICSS) algorithm and wavelet analysis. Specifically, we look at the effect of the outbreak of the Asian crisis and the terrorist attacks of September 11, 2001 on Emerging Asia. Europe. Latin America and North America's stock markets. In addition, we focus on the behavior of interest rates in Chile after the Central Bank switched its monetary policy interest rate from an inflation-indexed to a nominal target in August 2001. Our estimation results show that the number of shifts detected by the two methods is substantially reduced when filtering out the data for both conditional heteroskedasticity and serial correlation.
THE ASSOCIATION BETWEEN FRAILTY, DISCHARGE TO INSTITUTION, AND MORTALITY IN OLDER ADULTS UNDERGOING NON-ELECTIVE ABDOMINAL SURGERY

BACKGROUND: Older adults undergoing non-elective GI surgery experience increased morbidity and mortality when compared to younger and elective cohorts. Prognostic factors can be used to counsel patients of these risks and, if modifiable, to minimize them. The purpose of this study was to summarize the literature on prognostic factors for adverse outcomes in elderly patients undergoing non-elective GI surgery. STUDY DESIGN: PubMed and EMBASE were searched using a strategy developed in collaboration with an expert librarian. Studies that examined independent associations between prognostic factors and morbidity or mortality in patients aged ≥ 65 undergoing non-elective GI surgery were selected. Data were extracted using a standardized form, and quality of studies was assessed using the QUIPS tool. RESULTS: Nine cohort studies representing 2958 patients satisfied selection criteria. All studies focused on post-operative mortality. A total of 34 prognostic factors were examined and significant variability across studies was noted. Limited or conflicting evidence was found for the majority of prognostic factors examined. Meta-analysis was only possible for the ASA score, which was found to be associated with mortality in four studies (pooled OR = 2.77; 95% CI: 0.92-8.41). CONCLUSIONS: While non-elective GI surgery in older adults is becoming increasingly common, the literature on prognostic factors for morbidity and mortality in this patient population lags behind. Further research in this area is needed to help guide patient care and potentially improve outcomes.
Spinal shape analysis in 1,020 healthy young adults aged from 19 to 30 years

Background: A number of studies on diseased spine have been published; however, there is a relative paucity of studies investigating spine shape characteristics in healthy populations. Such characteristics are needed for diagnostics of spine disorders and assessment of changes in the spinal shape that may have been caused by influence of the modern life style or intensive sport activity. Objective: The aim of the study was to determine characteristics of the spine shape in a large sample of healthy young adults. Methods: Population cross-sectional study. A non-radiographic surface method (system DTP-3) was used for the assessment of spine shape in the sagittal and frontal planes. A total of 1,020 participants (440 men, 580 women) took part in the study, their mean (± SD) age was 21.8 ± 1.9 years (range 19.1-29.7) for men and 21.9 ± 1.8 years (range 19.3-29.7) for women. All data were checked for normality and are presented as means, standard deviations, ranges, skewness, and kurtosis. Differences between the sexes were assessed with the two-sample t-test. Results: The average sagittal spinal shape was C3 - 12.9° - C7 - 43.0° - T10 - 27.1° - L5 for men and C3 - 12.1° - C6 - 44.5° - T11 - 34.1° - L5 for women. Men showed a significantly smaller thoracic kyphosis and lumbar lordosis curvatures than women. The average curvature due to the lateral deviation in the frontal plane was 6.1° for both sexes, the curvature was larger than 10° in 9.1% of men and 8.8% of women. We found left lateral deviation in 72.5% of men and in 63.6% of women. Conclusions: The study provides characteristics of the spine shape in a large sample of healthy young adults. Such characteristics should be part and parcel of determining the cut-off level for physiological spinal shape. Based on the results of the study, we suggest a lateral deviation of 10° as the maximum for a curvature to be still considered non-pathological.
Evidence of anatase intergrowths formed during slow cooling of reduced ilmenite

Controlling the parameters during synthetic rutile production is essential to minimize production costs and ensure final product quality. Powder X-ray diffraction (PXRD) is typically used within the industry to guide process control. This work investigated the source of unusual features observed in the PXRD pattern of a slow-cooled reduced ilmenite (RI), which were not observed for a rapid-cooled RI. For the slow-cooled RI, the 002 peak of M3O5 (anosovite) had disappeared and the intensity of the \bar 203, 203, 204 and 402 peaks had decreased significantly compared to the pattern for the rapid-cooled RI. Using transmission electron microscopy, selected area electron diffraction (SAED) and pair distribution function (PDF) analysis, the authors attribute these features to M3O5–anatase intergrowth formation, which causes a loss in long-range order along the M3O5 c axis. Strong diffuse streaking in the SAED patterns was also evident and supported the presence of disordered intergrowths from the oxidation of M3O5. PDF analysis showed a significant improvement in the fit to the data for the slow-cooled RI, primarily in the <17 A region, when anatase was added to the PDF model. The results presented here highlight the importance of the reduction and cooling stages during the formation of these industrially relevant RI minerals, which may be used to direct the production process and final TiO2 product quality.
Experimental Study on the Origin of Cremated Bone Apatite Carbon

Bones that have undergone burning at high temperatures (i.e. cremation) no longer contain organic carbon. Lanting et al. (2001) proposed that some of the original structural carbonate, formed during bioapatite formation, survives. This view is based on paired radiocarbon dating of cremated bone apatite and contemporary charcoal. However, stable carbon isotope composition of carbonate in cremated bones is consistently light compared to the untreated material and is closer to the δ13C values seen in C3 plant material. This raises the question of the origin of carbonate carbon in cremated bone apatite. That is, does the isotope signal reflect an exchange of carbon with the local cremation atmosphere and thus with carbon from the burning fuel, or is it caused by isotopic fractionation during cremation? To study the changes in carbon isotopes (14C, 13C) of bone apatite during burning up to 800 °, a modern bovine bone was exposed to a continuous flow of an artificial atmosphere (basically a high-purity O2/N2 gas mix) under defined conditions (temperature, gas composition). To simulate the influence of the fuel carbon available under real cremation conditions, fossil CO2 was added at different concentrations. To yield cremated bone apatite properties similar to archaeological cremated bones, in terms of crystallographic criteria, water vapor had to be added to the atmosphere in the oven. Infrared vibrational spectra reveal large increases in crystal size and loss of carbonate upon cremation. The isotope results indicate an effective carbon exchange between bone apatite carbonate and CO2 in the combustion gases depending on temperature and CO2 concentration. 14C dates on archaeological cremated bone apatite may thus suffer from an old-wood effect. Paired 13C and 14C values indicate that in addition to this exchange, isotope fractionation between CO2 and carbonate, and admixture of carbon from other sources such as possibly collagen or atmospheric CO2, may play a role in determining the final composition of the apatite carbonate.
Determination of Carboxylic Acids in Apple Juice by RP HPLC

Low molecular weight organic acids are most predominant in apple juice among these components fumaric acid was not exceed more than 5 ppm. It was thought that the HPLC is the best method of the determination of organic acids in the apple juice. In this study, chromatographic separation of organic acids of apple juice was obtained by preparing a sample and by applying them to acid phase for extraction and various organic acids content of apple juice, fumaric acid, oxalic acid, tartaric acid and shikimic acids were commented as qualitative and quantitative, too. The organic acids, of which the chromatographic separations were examined, were the acids of fumaric acid, oxalic acid, tartaric acid, ascorbic acid, lactic acid, malic acid, succinic acid and shikimic acid. For this separation, the suitable value are determined by regulating the pH of mobile phase with phosphoric acid in range of pKa ±1.5 (This is the space in which the capacity factors are effectively changed). The concentration of juice was distilled to 11.2 Brix and same pH was applied to cartridge by adjusting with the phosphate buffer at 8.00, and the cartridge was washed with the same buffer and the phase was combined with the first eluant. A suitable distilled percentage of samples were injected and injection volume were determined. In this study, the cartridges of Supelco C18 and Waters C18 were used, datas obtained by both types of cartridges were compared. In this study, the methods of external calibration and added method of standards were applied and slopes were compared.
