description: We report a study of the 16.5 GHz dielectric function of hydrogenated and deuterated organic salts (TMTTF)$_2$PF$_6$. The temperature behavior of the dielectric function is consistent with short-range polar order whose relaxation time decreases rapidly below the charge ordering temperature. If this transition has more a relaxor character in the hydrogenated salt, charge ordering is strengthened in the deuterated one where the transition temperature has increased by more than thirty percent. Anomalies in the dielectric function are also observed in the spin-Peierls ground state revealing some intricate lattice effects in a temperature range where both phases coexist. The variation of the spin-Peierls ordering temperature under magnetic field appears to follow a mean-field prediction despite the presence of spin-Peierls fluctuations over a very wide temperature range in the charge ordered state of these salts.

description: Deep learning based generative models such as deepfake have been able to generate amazing images and videos. However, these models may need significant transformation when applied to generate crystal materials structures in which the building blocks, the physical atoms are very different from the pixels. Naively transferred generative models tend to generate a large portion of physically infeasible crystal structures that are not stable or synthesizable. Herein we show that by exploiting and adding physically oriented data augmentation, loss function terms, and post processing, our deep adversarial network (GAN) based generative models can now generate crystal structures with higher physical feasibility and expand our previous models which can only create cubic structures.

description: Nanoscale biosystems are widely used in numerous medical applications. The approaches for structure and function of the nanomachines that are available in the cell (natural nanomachines) are discussed. Molecular simulation studies have been extensively used to study the dynamics of many nanomachines including ribosome. Carbon Nanotubes (CNTs) serve as prototypes for biological channels such as Aquaporins (AQPs). Recently, extensive investigations have been performed on the transport of biological nanosystems through CNTs. The results are utilized as a guide in building a nanomachinary such as nanosyringe for a needle free drug delivery.

title: Dynamics of Arid-land, Perennial Plant Populations with an Examination of Potential Causal Agents
Creators: name: Gardiner, Henry George
Publisher: name: Utah State University
Year: 1984

description: Rigorous statistical examination of the population dynamics of a number of long-lived perennial plant species permitted an interpretation of changes in those populations and the establishment of potentially important causal agents. Survival and recruitment of six species from the mulga-zone rangelands of Western Australia varied across three climatically different periods following the removal of domestic livestock.
Two species' populations (Eragrostis xerophila and Maireana glomerifolia) had their rates of increase reduced by kangaroo and euro grazing. Both survival and recruitment of Eragrostis xerophila were reduced by this grazing while Maireana glomerifolia suffered reduced recruitment during all periods. These negative effects were most pronounced during the post-drought period of more "normal" rainfall. Three other species populations responded positively to grazing. Recruitment and survival of Eremophila spectabilis, were affected by grazing, particularly on a poor condition site, while differences in recruitment were more important for Eremophila leucophylla. Frankenia pauciflora had increased recruitment and survival during the postdrought period. The sixth species (Ptilotus obovatus) suffered increased mortality and reduced recruitment during the post-drought period.
Relative rates of change in management related groups of 18 species, including the six examined in more detail, were presented as a viable addition to the analysis of trend in rangeland vegetation. Grazing by kangaroos significantly reduced the rate of recovery of destocked rangeland pastures.
Site and seasonal factors affected all species populations examined. Site induced differences affected survival of all six species examined, highlighting the difficulty of replicating large scale experiments in rangeland vegetation. Different seasonal sequences (very wet, very dry, and more "normal") produced different species population responses. Populations of most species increased during the very wet, and more "normal", post-drought period, but declined, or remained static, during the drought. Potentially competitive relationships were examined at one site where the complexity of juvenile plant survival responses to seasonal conditions, treatment and to neighbor-free-space suggest potential competition, but more importantly reflect a need for more detailed study.
A re-examination of Danthonia caespitosa population data collected by O.B. Williams in rangeland areas of New South Wales indicates the importance of grazing by merino sheep, seasonal conditions, and the cohort within which a plant is recruited. The extreme variability of the data highlights the need for experimental designs that take account of the frequency and importance of causal agent impact, and are related to the dynamism of the population.

antibiotics resistance genes
mobile genetic elements

description: Human waste-based fertilizers contribute to sustainable agriculture by reusing valuable nutrients. However, these fertilizers may contain antibiotics and antibiotic resistance genes (ARGs) which spread among soil microorganisms by horizontal gene transfer using mobile genetic elements (MGEs). The goal of this study was to investigate the effect of antibiotics, commonly found in human waste-based fertilizers, on the soil microbial community and its resistome. A greenhouse trial was conducted where spinach and radish were exposed to a mix of five antibiotics (clarithromycin, sulfamethoxazole, trimethoprim, chlortetracycline and enrofloxacin). This mix was applied in four concentrations (0, 0.1, 1.0 and 10.0 mg/kg soil dry weight). The crops were grown for 6 weeks, after which samples were collected for metabarcoding (16S and ITS) and qPCR analysis. The metabarcoding data was analysed using a customised pipeline. For the qPCR, four ARG and two MGE targets were selected, namely sul1, dfrA12, tetQ, qnrS1, intI-1 and intI-2. Preliminary results of the metabarcoding show a shift of the soil bacterial community for both crops. Here, the 0 mg/kg treatment was significantly different than the 0.1 and 1.0 mg/kg treatment. For the resistome, sul1 and intI-1 were consistently found across all samples. Moreover, their abundance increased in the 0.1 and 1.0 mg/kg treatments compared to the 0 mg/kg control treatment. Detailed analysis of the soil microbial community, to be performed, will link the antibiotic distribution to the soil microbial community and its resistome. Our study shows that low antibiotic concentrations have the potential to increase ARG abundance. While these genes are not necessarily present in pathogens nor do they usually spread to clinical settings, soil antibiotic resistance has been linked to antibiotic resistant clinical pathogens. Therefore, it is important to better understand how these genes behave and disseminate in agriculture with waste-based fertilizers potentially containing antibiotics.

description: O presente artigo pretende contribuir para a abordagem etnomusicológica ao Festival RTP da Canção (1964 2014). Pela sua longevidade e por ter atraves sado momentos chave na história de Portugal e da Europa, importa compreender a sua relevância no âmbito da criação musical e da representação de identidades aos níveis nacional e internacional. A abordagem feita na Enciclopédia da Música em Portugal no Séc ulo XX (2010), a primeira em Portugal no âmbito da etnomusicologia, é fundamental para o debate em torno deste concurso e um ponto de partida para a minha investigação. Considerando a escassez de trabalhos publicados em Portugal relativamente à importância da mú sica na televisão e deste concurso em particular, este artigo visa contribuir para a compreensão deste fenómeno musical e televisivo ao longo de cinquenta anos. Uma vez que é resultado do trabalho de investigação ainda em curso (Doutoramento em Etnomusicologia, FCSH-NOVA, Lisboa), recentemente financiado pela FCT, debatem se as possíveis abordagens ao tema, tendo como fundamento tanto os estudos internacionais como os poucos contributos nacionais.

description: We combine in a single framework the two complementary benefits of chi^2-template fits and empirical training sets used e.g. in neural nets: chi^2 is more reliable when its probability density functions (PDFs) are inspected for multiple peaks, while empirical training is more accurate when calibration and priors of query data and training set match. We present a chi^2-empirical method that derives PDFs from empirical models as a subclass of kernel regression methods, and apply it to the SDSS DR5 sample of >75,000 QSOs, which is full of ambiguities. Objects with single-peak PDFs show <1% outliers, rms redshift errors <0.05 and vanishing redshift bias. At z>2.5, these figures are 2x better. Outliers result purely from the discrete nature and limited size of the model, and rms errors are dominated by the instrinsic variety of object colours. PDFs classed as ambiguous provide accurate probabilities for alternative solutions and thus weights for using both solutions and avoiding needless outliers. E.g., the PDFs predict 78.0% of the stronger peaks to be correct, which is true for 77.9% of them. Redshift incompleteness is common in faint spectroscopic surveys and turns into a massive undetectable outlier risk above other performance limitations, but we can quantify residual outlier risks stemming from size and completeness of the model. We propose a matched chi^2-error scale for noisy data and show that it produces correct error estimates and redshift distributions accurate within Poisson errors. Our method can easily be applied to future large galaxy surveys, which will benefit from the reliability in ambiguity detection and residual risk quantification.

Individuação, performance e improvisação no jazz: proposta exploratória

description: A prática da improvisação demanda respostas em tempo “real” a inúmeros acontecimentos que emergem da intensidade dos processos generativos em jogo. Durante a improvisação, a escuta é técnica fulcral para a elaboração da reação do músico e se configura no próprio ato performativo. As habilidades de emitir e modelar-se por meio das respostas instantâneas são características identificadoras do performer, e exigem ativação permanente de um modo de atenção sensível, e da subjetivação. Para o filósofo francês Gilbert Simondon, no sistema indivíduo-mediação-mundo, ocorrem simultaneamente os processos de individuação singular e coletiva, esta última denominada transindividuação. Proponho que a escuta também é sistema em individuação. Seja como comportamento, técnica ou pensamento, ela é uma das características primordiais da subjetividade do artista. A partir deste enfoque, analiso uma entrevista com um músico profissional e apresento resultados que sinalizam a viabilidade deste marco teórico para o estudo sobre o sistema músico-mediação-mundo e a relação de mutualidade entre suas individuações.

description: The nearby Seyfert type galaxy NGC 1275 contains a bright radio nucleus at its center, revealed through high-spatial resolution imaging to be the source of the jets emanating from the galaxy. Coincident with the emergence of a new component C3 in the nucleus since 2005, flux densities from NGC 1275, at least at radio, millimeter (mm), and gamma-ray frequencies, had been increasing up through 2017 and leveled off afterwards. We analyze the long-term light curves of the nucleus that span the rising trend to 2015 July, and find a pair of approximately year-long quasi-periodic oscillations, with periods of $P_l\simeq 345$\,d and $P_h\simeq 386$\,d respectively, in emission at 1.3-mm wavelength. We discuss the case that there would be a long precession period $P_{\rm prec}\simeq 9$\,yr, causing the appearance of $P_h$ that is slightly higher than $P_l$. The accretion disk around the central supermassive black hole (SMBH) would be precessing at $P_{\rm prec}$, induced by either the Lense-Thirring effect or the existence of a companion SMBH. In the two scenarios, $P_l$ would be the jet wobbling timescale or the SMBH binary period respectively. The finding, which could be verified through high-spatial resolution mm imaging, would not only identify the nature of the jet variation but also help reveal the full features of the galaxy.

description: A nearby core collapse supernova will produce a burst of neutrinos in several detectors worldwide. With reasonably high probability, the Earth will shadow the neutrino flux in one or more detectors. In such a case, for allowed oscillation parameter scenarios, the observed neutrino energy spectrum will bear the signature of oscillations in Earth matter. Because the frequency of the oscillations in energy depends on the pathlength traveled by the neutrinos in the Earth, an observed spectrum contains also information about the direction to the supernova. We explore here the possibility of constraining the supernova location using matter oscillation patterns observed in a detector. Good energy resolution (typical of scintillator detectors), well known oscillation parameters, and optimistically large (but conceivable) statistics are required. Pointing by this method can be significantly improved using multiple detectors located around the globe. Although it is not competitive with neutrino-electron elastic scattering-based pointing with water Cherenkov detectors, the technique could still be useful.

description: Este trabalho apresenta parte da análise sobre o material etnográfico acumulado ao longo dos últimos seis anos de pesquisa junto ao Grupo Arautos do Gueto, na favela do Morro das Pedras, Belo Horizonte. Nestes seis anos de pesquisa, que abrangem a Iniciação Científica, Mestrado e uma parte do Doutorado, a observação participativa combinada com a pesquisa-ação e a extensão universitária, vem sendo o procedimento adotado. As reflexões aqui apresentadas articulam o material etnografado com as noções de: musicalidade como habilidade não ontológica e sim socialmente apreendida de expressão através de organização de sons; linguagem e sistema musicais como frutos dos processos sócio-históricos de desenvolvimento da musicalidade em cada sistema cultural; bimusicalidade como habilidade em apreender um segundo sistema (idioma) musical distinto do sistema materno; as diferenças de linguagem entre os sistemas musicais euro-ocidental, dominante na universidade brasileira, e o afro-brasileiro, dominante na maioria das favelas e outras regiões do Brasil; as discussões pós-colonialistas que tratam das disparidades socioculturais em ex-colônias como continuação histórica das disparidades na relação entre colonizador e colonizado; a disparidade de poder entre o etnomusicólogo brasileiro e as comunidades brasileiras onde este empreende pesquisa, e a bimusicalidade como recurso do etnomusicólogo formado pela universidade brasileira onde o sistema musical hegemônico é o euro-ocidental e que vai às favelas e comunidades onde o sistema musical hegemônico é outro. Concluo refletindo como, no caso da pesquisa em andamento, a bimusicalidade é apontada como um recurso importante do processo pedagógico e para amadurecimento da relação entre universidade e favela.

description: Despite significant advancements of deep learning-based forgery detectors for distinguishing manipulated deepfake images, most detection approaches suffer from moderate to significant performance degradation with low-quality compressed deepfake images. Because of the limited information in low-quality images, detecting low-quality deepfake remains an important challenge. In this work, we apply frequency domain learning and optimal transport theory in knowledge distillation (KD) to specifically improve the detection of low-quality compressed deepfake images. We explore transfer learning capability in KD to enable a student network to learn discriminative features from low-quality images effectively. In particular, we propose the Attention-based Deepfake detection Distiller (ADD), which consists of two novel distillations: 1) frequency attention distillation that effectively retrieves the removed high-frequency components in the student network, and 2) multi-view attention distillation that creates multiple attention vectors by slicing the teacher's and student's tensors under different views to transfer the teacher tensor's distribution to the student more efficiently. Our extensive experimental results demonstrate that our approach outperforms state-of-the-art baselines in detecting low-quality compressed deepfake images.

description: We present a methodology to train our multi-speaker emotional text-to-speech synthesizer that can express speech for 10 speakers' 7 different emotions. All silences from audio samples are removed prior to learning. This results in fast learning by our model. Curriculum learning is applied to train our model efficiently. Our model is first trained with a large single-speaker neutral dataset, and then trained with neutral speech from all speakers. Finally, our model is trained using datasets of emotional speech from all speakers. In each stage, training samples of each speaker-emotion pair have equal probability to appear in mini-batches. Through this procedure, our model can synthesize speech for all targeted speakers and emotions. Our synthesized audio sets are available on our web page.

description: O presente artigo reflete um estudo que investiga o impacto da música na melhoria da qualidade de vida de uma população de adultos com deficiência mental, sensorial e motora, ao nível dos seus comportamentos e capacidades de comunicação e expressão interpessoal. Sob a premissa de que a educação é um direito social de todos os indivíduos, independentemente das suas condições biológicas, económicas, sociais ou faixa etária, esta investigação procurou fornecer oportunidades igualitárias e multifacetadas segundo os interesses e necessidades de uma comunidade em particular, utilizando a música enquanto veículo eficaz nas trocas sociais não-verbais e na promoção de bem-estar. Foi conduzida uma intervenção prática semanal durante o ano letivo de 2014/2015, ao longo de 10 meses, junto de uma comunidade de adultos com multideficiência. Após terem sido delineados os objetivos específicos e individuais, realizaram-se dois períodos de experimentação, entre os quais se procedeu à aferição de ferramentas. Os resultados das sessões musicais implementadas foram avaliados através de uma escala de avaliação e de questionários. Provou-se que todos os objetivos foram concretizados e concluiu-se que a música pode proporcionar melhorias significativas na qualidade de vida de uma população com deficiência ou incapacidade.

title: Changes in Spider Community Attributes Along a Subalpine Successional Gradient
Creators: name: Waagen, Gerald Norman
Publisher: name: Utah State University
Year: 1979

description: The spider communities of four stages of a successional sere leading to and including spruce forests were studied in northern Utah. Four seral stages were recognized. These include: meadows, aspen (Populus tremuloides) stands, subalpine fir (Abies lasiocarpa) forest, and the climax Engelmann spruce (Pica engelmanii) forests.
During the snow-free periods of 1976, 1977 and 1978, 15,987 spiders were collected by three methods including: pitfall traps, by beating vegetation, and with sweep-net samples. Additionally, 1600 15-second intervals of behavioral observations, and measurements of 182 web locations were made.
Of 99 species collected, 44 were considered residents of the sere: criteria for assigning the spiders to foraging strategies (3) and guilds (9) are presented. Five spider communities were ostensively defined--one in the ground stratum of each of the stages and one in the tree stratum of the conifer stages.
The data were used to compare the guild strategies of the spiders of the seral stages and to address various hypotheses about successional change in animal community characteristics. Increases with maturity as predicted were observed for 6 spider community parameters including: total biomass, species diversity--richness component, species diversity--equitability component, stratification and spatial heterogeneity, mean organism size, and temporal stratification. A life cycle hypothesis (i.e., short and simple life cycles in early stages, long and complex ones in mature stages) could not be tested because, depending on the life cycle type considered, I found diametrically opposed trends (semi-annual and biennial life cycle types both increased with maturity).
The spider species of the ground-stratum meadow community were primarily dispersed in a time dimension (seasonal); the spiders of the tree-stratum community were primarily distributed in a spatial dimension (microhabitat). Spiders of the forest ground-strata communities were dispersed in spatial and temporal dimensions. No dimension was ascertained to be of fundamental importance.
Distributions of ground-dwelling species with different foraging strategies, and the resident species of the ground-stratum communities were correlated canonically to 8 environmental variables. Spider species of the meadow community were correlated with a bare dirt variable. Spiders of the aspen community were correlated with 2 environmental variables including: grasses and forbs and a low foliage index. Hunting spiders were correlated with the meadow and aspen variables. Ambushing spiders, web-building spiders, and the spider species of the ground stratum spruce community were correlated with 5 environmental variables including: litter depth, canopy cover, tree basal area, dead leaves and needles, and logs.

A metodologia e a prática de investigação artística, utilizando tecnologias multimédia, foram apresentadas através da definição da dinâmica de construção coreográfica e da procura de uma linguagem despojada e significativa inerente à vivência de posturas e narrativas a partir do Yoga. Na primeira parte, apresentei um momento performativo de 20 minutos, com excertos da obra coreográfica “Inspiração”, criada no âmbito do doutoramento e que simboliza o meu encontro com o Yoga que me impulsionou para um outro nível de entendimento da Dança. Na segunda parte dei a conhecer a dinâmica da prática artística utilizada, recorrendo a um vídeo que documenta a fase de ensaios de criação coreográfica e que mostra de forma resumida o meu método de trabalho.

description: O presente artigo origina se de pesquisa em andamento que propõe uma investigação sobre o processo de transcrição e performance na guitarra das sonatas de Domenico Scarlatti. Neste trabalho são apresentadas uma análise e discussão sobre algumas das princi pais escolhas dos guitarristas ao interpretarem o texto musical scarlattiano. Para a observação destas práticas, foram selecionadas sete sonatas em versões de guitarristas de renome, e utilizados os seguintes parâmetros: adaptações do texto original, recur sos instrumentais, articulação e ornamentação. De maneira a sistematizar a investigação deste material, foram utilizadas as seguintes ferramentas: análise das transcrições dos guitarristas (partituras e gravações), pesquisa bibliográfica e registro diário do processo de estudo destas sonatas na guitarra. A partir da investigação realizada, foi possível o reconhecimento de tendências gerais dos guitarristas na prática deste repertório, tais como: uniformidade de articulação, uniformidade de timbre, e execuçã o de ornamentos em duas cordas. Além disso, foram identificadas soluções pouco convencionais, que abrem caminho para novas abordagens de transcrição.

description: In this work, we explore the potential of multi-domain multi-branch convolutional neural networks (CNNs) for identifying comparatively rare giant radio galaxies from large volumes of survey data, such as those expected for new-generation radio telescopes like the SKA and its precursors. The approach presented here allows models to learn jointly from multiple survey inputs, in this case NVSS and FIRST, as well as incorporating numerical redshift information. We find that the inclusion of multi-resolution survey data results in correction of 39% of the misclassifications seen from equivalent single domain networks for the classification problem considered in this work. We also show that the inclusion of redshift information can moderately improve the classification of giant radio galaxies.

title: The Redevelopment of Plant Community Diversity on a Surface Coal Mine in Southwestern Wyoming
Creators: name: Hatton, Thomas Joseph
Publisher: name: Utah State University
Year: 1986

description: A study was initiated in 1981 to investigate the redevelopment of plant communities on a recontoured, surface-mined site in southwestern Wyoming. The landscape pattern of vegetation was compared with topographic position, the initial topsoil pattern, and cultural practices including shrub planting density, shrub planting pattern and topsoil treatments for the years 1982-1985. In addition, differences in vascular plant species diversity within these various factors and treatments were determined, along with the trend in intracommunity (alpha), intercommunity (beta) and landscape (gamma) diversity for the entire study area.
The influence of site factors and tested cultural practices on the differentiation of the landscape vegetation pattern generally declined over time. There were no persistent differences in diversity among any cultural treatments or topographic positions, with the exception of plan ting pattern. The vegetation classified by cultural treatment, topographic position, or the initial plant comm uni ties identified in 1982 showed strong successional convergence by 1985. This is reflected in a decline in be ta and gamma diversity over the period 1984-1985. Alpha diversity remained stable over this same period, though species richness increased, indicating that a subset of species is becoming more dominant. The landscape vegetation pattern apparently converged to a rather uniform composition, increasingly dominated by perennial grasses, forbs and shrubs.

description: We describe a method for evolving the projected Gross-Pitaevskii equation (PGPE) for an interacting Bose gas in a harmonic oscillator potential, with the inclusion of a long-range dipolar interaction. The central difficulty in solving this equation is the requirement that the field is restricted to a small set of prescribed modes that constitute the low energy c-field region of the system. We present a scheme, using a Hermite-polynomial based spectral representation, that precisely implements this mode restriction and allows an efficient and accurate solution of the dipolar PGPE. We introduce a set of auxiliary oscillator states to perform a Fourier transform necessary to evaluate the dipolar interaction in reciprocal space. We extensively characterize the accuracy of our approach, and derive Ehrenfest equations for the evolution of the angular momentum.

Mental ability profiles in kindergarten children of different ethnic groups
Creators: name: Van Blankenstein, Barbara Jean
Publisher: name: University of British Columbia
Year: 2011

description: Data from 7 subtests of the MPI were analyzed for 120 kindergarten children in a low socio-economic area of Greater Vancouver. The subtests were selected as being representative of components of a mental ability profile (MAP) and included categories of IQ, spatial conceptualization, abstract reasoning, verbal comprehension and generic and word production. Classification of the data into 2 levels of age (5 yrs. 3 mos. - 5 yrs. 10 mos.; 5 yrs. 11 mos. - 6 yrs. 6 mos.), 2 levels of score on the MPI (4 - 7; 8 -11), and 3 levels of ethnic group (Chinese, Italian and Canadian) gave 2 contrasting MAPS. The Chinese MAP was distinctively different from the Italian and Canadian MAPS which closely resembled each other. Significant differences appeared (p<.01) for all categories between ethnic groups with the exception of verbal comprehension. Age was not a significant factor in any category. Scoring levels were significantly different (p<.01) but each ethnic group retained its MAP at both low and high levels of scoring.
FRB 190520B embedded in a magnetar wind nebula and supernova remnant: luminous persistent radio source, decreasing dispersion measure and large rotation measure

description: Recently, FRB 190520B with the largest extragalactic dispersion measure (DM), was discovered by the Five-hundred-meter Aperture Spherical radio Telescope (FAST). The DM excess over the intergalactic medium and Galactic contributions is estimated as $\sim 900$ pc cm$^{-3}$, which is nearly ten times higher than other fast radio bursts (FRBs) host galaxies. The DM decreases with the rate $\sim0.1$ pc cm$^{-3}$ per day. It is the second FRB associated with a compact persistent radio source (PRS). The rotation measure (RM) is found to be larger than $1.8 \times 10^{5} \mathrm{rad} ~\mathrm{m}^{-2}$. In this letter, we argue that FRB 190520B is powered by a young magentar formed by core-collapse of massive stars, embedded in a composite of magnetar wind nebula (MWN) and supernova remnant (SNR). The energy injection of the magnetar drives the MWN and SN ejecta to evolve together, and the PRS is generated by the synchrotron radiation of the MWN. The magnetar has the interior magnetic field $B_{\text{int}}\sim (2-4)\times 10^{16}$ G and the age $t_{\text{age}}\sim 14-22$ yr. The dense SN ejecta and the shocked shell contribute a large fraction of the observed DM and RM. Our model can naturally explain the luminous PRS, decreasing DM and extreme RM of FRB 190520B simultaneously.

Para além de “Vigiar e Punir”: a prática de piano numa experiência em contexto prisional

description: Em Vigiar e Punir, Michel Foucault identifica a disciplina e a “docilização" como os dois principais processos utilizados nas prisões para moldar e controlar os corpos e a vontade dos indivíduos, tentando dessa forma reconstruir identidades que correspondam aos padrões de comportamento exigidos para viver em sociedade. Estas estratégias são, no entanto, criticadas por muitos, e diferentes sistemas prisionais procuram atividades e programas que possam contribuir positivamente para a experiência de reclusão. Este artigo descreve o projeto "Nas asas de um piano... aprendo a voar" desenvolvido em 2013-2014 numa prisão feminina em Portugal. Partindo de atividades como a improvisação, composição e memorização de peças simples, abordando também princípios básicos de leitura de partitura numa fase posterior, as sessões individuais evoluíram até à apresentação de 3 diferentes concertos, dentro e fora da prisão. Com base nesta experiência, é feita uma reflexão sobre o fosso que separa a experiência vivida neste projecto e o ambiente hostil descrito por Foucault, encontrando evidências claras de que a música é uma poderosa ferramenta para o Desenvolvimento Humano: catalisa emoções, abre canais de comunicação entre indivíduos, promove a autoeficácia, a confiança, o perdão e motivação para descobrir e experimentar outras experiências.

description: Safe exploration is critical for using reinforcement learning (RL) in risk-sensitive environments. Recent work learns risk measures which measure the probability of violating constraints, which can then be used to enable safety. However, learning such risk measures requires significant interaction with the environment, resulting in excessive constraint violations during learning. Furthermore, these measures are not easily transferable to new environments. We cast safe exploration as an offline meta-RL problem, where the objective is to leverage examples of safe and unsafe behavior across a range of environments to quickly adapt learned risk measures to a new environment with previously unseen dynamics. We then propose MEta-learning for Safe Adaptation (MESA), an approach for meta-learning a risk measure for safe RL. Simulation experiments across 5 continuous control domains suggest that MESA can leverage offline data from a range of different environments to reduce constraint violations in unseen environments by up to a factor of 2 while maintaining task performance.

description: Neutron diffraction measurements have been performed on a powder sample of BaMn2As2 over the temperature T range from 10 K to 675 K. These measurements demonstrate that this compound exhibits collinear antiferromagnetic ordering below the Neel temperature T_N = 625(1) K. The ordered moment mu = 3.88(4) mu_B/Mn at T = 10 K is oriented along the c axis and the magnetic structure is G-type, with all nearest-neighbor Mn moments antiferromagnetically aligned. The value of the ordered moment indicates that the oxidation state of Mn is Mn^{2+} with a high spin S = 5/2. The T dependence of mu suggests that the magnetic transition is second-order in nature. In contrast to the closely related AFe2As2 (A = Ca, Sr, Ba, Eu) compounds, no structural distortion is observed in the magnetically ordered state of BaMn2As2.
