Correction system for polyphonic piano recordings

M.I. Martin-Erdozain, I. Barbancho, A. Rosa-Pujazon, A.M. Barbancho, "Correction system for polyphonic piano recordings", XXVIII Simposium Nacional de la Unión Científica Internacional de Radio, Santiago de Compostela, España, 2013n this paper, a support tool for piano rehearsal is presented. The system analyses a given piano polyphonic recording to find the times, pitch and duration of the notes and figures played, taking into account the possibility of playing more than one note simultaneously as well as covering the whole piano frequency range. In order to do so, the system uses an onset detection algorithm to segment the input signal into partitions which are then analysed in the time and frequency domains. Then, the system correlates the data extracted from the partitions with the score of the original piece, identifying the positions and type of the mistakes performed by the user, and providing her/him with the corresponding feedback. The experiments conducted showed that the application is capable of analysing a given recording and indicate the musician the mistakes made.This work has been funded by the Ministerio de Economia y Competitividad of the Spanish Government under Project No. TIN2010-21089-C03-02 and by the Ministerio de Industria, Turismo y Comercio under Project No. TSI-090100-2011-25

Machine-Learned Exclusion Limits without Binning

Machine-Learned Likelihoods (MLL) is a method that, by combining modern machine-learning classification techniques with likelihood-based inference tests, allows to estimate the experimental sensitivity of high-dimensional data sets. We extend the MLL method by including the exclusion hypothesis tests and show that the addition of Kernel Density Estimators avoids the need to bin the classifier output in order to extract the resulting one-dimensional signal and background probability density functions. We first test our method on toy models generated with multivariate Gaussian distributions, where the true probability distribution functions are known. We then apply it to a case of interest in the search for new physics at the HL-LHC, in which a $Z^\prime$ boson decays into lepton pairs, comparing the performance of our method for estimating 95\% CL exclusion limits to the results obtained applying a binned likelihood to the machine-learning classifier output.Comment: 14 pages, 3 figures.

El objetivo final de este libro es el mismo: incorporar cada vez más bibliografía que enriquezca las opciones de consulta por parte de interesados en aspectos particulares y, desde luego, divulgar nuevos conocimentos y ofrecer los resultados del quehacer universitario

An apoptotic caspase network safeguards cell death induction in pyroptotic macrophages

Pyroptosis has emerged as a key mechanism by which inflammasomes promote host defense against microbial pathogens and sterile inflammation. Gasdermin D (GSDMD)-mediated cell lysis is a hallmark of pyroptosis, but our understanding of cell death signaling during pyroptosis is fragmented. Here, we show that independently of GSDMD-mediated plasma membrane permeabilization, inflammasome receptors engage caspase-1 and caspase-8, both of which redundantly promote activation of apoptotic executioner caspase-3 and caspase-7 in pyroptotic macrophages. Impaired GSDMD pore formation downstream of caspase-1 and caspase-8 activation suffices to unmask the apoptotic phenotype of pyroptotic macrophages. Combined inactivation of initiator caspase-1 and caspase-8, or executioner caspase-3 and caspase-7, is required to abolish inflammasome-induced DEVDase activity during pyroptosis and in apoptotic Gsdmd(-/-) cells. Collectively, these results unveil a robust apoptotic caspase network that is activated in parallel to GSDMD-mediated plasma membrane permeabilization and safeguards cell death induction in pyroptotic macrophages

Accounting for pastoralists in Argentina

No official statistics exist on pastoralism in Argentina, so their number is not known. Between 30,000 to 35,000 households practise pastoralism, estimates Red Chaco based on the 2018 National Census. In some areas, pastoralism is alive as a mobile, extensive production system. Despite the uncertainty about the precise numbers, pastoralists play a significant role in Argentinian agriculture and society. Argentina is a large but highly urbanized country, with 92% of the population living in towns and cities. Only 13.2% of the country is agriculturally well endowed; 70% of the land is semi-arid, and much of the rest is mountainous or too cold for growing crops. Livestock-raising is the main form of agriculture in such marginal areas, either as ranching or as pastoralism.Estación Experimental Agropecuaria BarilocheFil: Lanari, Maria Rosa.

Males self-assessment of sexual maturation using drawings and photos

A avaliação da idade biológica de adolescentes participantes de programas esportivos é importante devido às relações existentes entre o desempenho esportivo e as modificações decorrentes da maturação sexual que ocorrem no período da puberdade. A idade biológica pode ser determinada através da idade dentária, da idade de maturação sexual, assim como do peso e da estatura do jovem, em relação à idade cronológica (Marcondes, Berquó, Hegg, Colli & Zacchi, 1987). Na área de educação física e do esporte, os meios mais empregados são as avaliações antropométricas do peso e da estatura. A avaliação da maturação sexual através dos estágios de desenvolvimento de pilosidade pubiana, mamas e genitais, conforme o método proposto por Tanner (1962), não é de fácil aplicabilidade dadas as condições exigidas pelo método, ou seja, necessidade de médico especializado, local adequado, além do constrangimento causado por este tipo de avaliação que pode gerar desconforto ao avaliado. O objetivo deste estudo foi comparar a precisão da autoavaliação da maturação sexual, de acordo com os estágios propostos por Tanner (1962), realizada através de desenhos de Morris e Udry (AD) e através de fotos de Tunner (AF), com a avaliação médica (AM). A amostra foi composta por 347 meninos, na faixa etária entre 10 e 16 anos, avaliados em três momentos diferentes. Na análise dos dados foram calculados os percentuais de concordância, de sub-estimativa e superestimativa, assim como o índice Kappa. O índice de Kappa variou entre 0,35 e 0,66. A auto-avaliação da pilosidade pubiana mostrou-se mais eficaz do que a auto-avaliação do estágio de desenvolvimento de genitais. Concluímos que os adolescentes podem avaliar precisamente seu próprio estágio de desenvolvimento de acordo com os estágios apresentados por fotos ou desenhos.The evaluation of biological age in young participants of sport programs is important because of the relationship between sport performance and physical modifications due to sexual maturation during puberty. The biological age can be determined by dental age, sexual maturation, height and weight of the young athlete, in relation to the chronological age. In the field of sport and physical education, measurements of weight and height are commonly used as indicators of biological maturation. The evaluation of the stages of sexual maturation, by the method proposed by Tanner (1962), is not easy due to the necessity of a specialized physician and a very private room. Besides, the whole procedure is extremely embarrassing for the subject. Therefore, the purpose of this study was to determine the agreement between the adolescent’s self-assessment of maturation using Morris e Udry’s drawings (AD) and Tunner’s standard photographs (AF), and the physician’s evaluation (ME). The sample was composed of 347 males, with ages between 10 and 16 years, evaluated at three different moments. In data analysis, the percentage of agreement, underestimation and overestimation of maturation stages were calculated as well as Kappa coefficients. The Kappa coefficients varied between 0.35 and 0.66. The self-assessment of pubic hair stage seemed to be more efficient than the self-assessment of genital stage. We concluded that adolescents can accurately assess their own developmental stage according to standard photographs standard drawings

A model based on the quantification of complement C4c, CYFRA 21-1 and CRP exhibits high specificity for the early diagnosis of lung cancer

Lung cancer screening detects early-stage cancers, but also a large number of benign nodules. Molecular markers can help in the lung cancer screening process by refining inclusion criteria or guiding the management of indeterminate pulmonary nodules. In this study, we developed a diagnostic model based on the quantification in plasma of complement-derived fragment C4c, cytokeratin fragment 21-1 (CYFRA 21-1) and C-reactive protein (CRP). The model was first validated in two independent cohorts, and showed a good diagnostic performance across a range of lung tumor types, emphasizing its high specificity and positive predictive value. We next tested its utility in two clinically relevant contexts: assessment of lung cancer risk and nodule malignancy. The scores derived from the model were associated with a significantly higher risk of having lung cancer in asymptomatic individuals enrolled in a computed tomography (CT)-screening program (OR = 1.89; 95% CI = 1.20–2.97). Our model also served to discriminate between benign and malignant pulmonary nodules (AUC: 0.86; 95% CI = 0.80–0.92) with very good specificity (92%). Moreover, the model performed better in combination with clinical factors, and may be used to reclassify patients with intermediate-risk indeterminate pulmonary nodules into patients who require a more aggressive work-up. In conclusion, we propose a new diagnostic biomarker panel that may dictate which incidental or screening-detected pulmonary nodules require a more active work-up

Motor Decline in Clinically Presymptomatic Spinocerebellar Ataxia Type 2 Gene Carriers

BACKGROUND: Motor deficits are a critical component of the clinical characteristics of patients with spinocerebellar ataxia type 2. However, there is no current information on the preclinical manifestation of those motor deficits in presymptomatic gene carriers. To further understand and characterize the onset of the clinical manifestation in this disease, we tested presymptomatic spinocerebellar ataxia type 2 gene carriers, and volunteers, in a task that evaluates their motor performance and their motor learning capabilities. METHODS AND FINDINGS: 28 presymptomatic spinocerebellar ataxia type 2 gene carriers and an equal number of control volunteers matched for age and gender participated in the study. Both groups were tested in a prism adaptation task known to be sensible to both motor performance and visuomotor learning deficits. Our results clearly show that although motor learning capabilities are intact, motor performance deficits are present even years before the clinical manifestation of the disease start. CONCLUSIONS: The results show a clear deficit in motor performance that can be detected years before the clinical onset of the disease. This motor performance deficit appears before any motor learning or clinical manifestations of the disease. These observations identify the performance coefficient as an objective and quantitative physiological biomarker that could be useful to assess the efficiency of different therapeutic agents

Fiber Optic Sensing System for Temperature and Gas Monitoring in Coal Waste Pile Combustion Environments

International audienceIt is presented an optical fiber sensing system projected to operate in the demanding conditions associated with coal waste piles in combustion. Distributed temperature measurement and spot gas sensing are requirements for such a system. A field prototype has been installed and is continuously gathering data, which will input a geological model of the coal waste piles in combustion aiming to understand their dynamics and evolution. Results are presented on distributed temperature and ammonia measurement, being noticed any significant methane emission in the short time period considered. Carbon dioxide is also a targeted gas for measurement, with validated results available soon. The assessment of this technology as an effective and reliable tool to address the problem of monitoring coal waste piles in combustion opens the possibility of its widespread application in view of the worldwide presence of coal related fires
