EDGE: Editable Dance Generation From Music

Dance is an important human art form, but creating new dances can be difficult and time-consuming. In this work, we introduce Editable Dance GEneration (EDGE), a state-of-the-art method for editable dance generation that is capable of creating realistic, physically-plausible dances while remaining faithful to the input music. EDGE uses a transformer-based diffusion model paired with Jukebox, a strong music feature extractor, and confers powerful editing capabilities well-suited to dance, including joint-wise conditioning, and in-betweening. We introduce a new metric for physical plausibility, and evaluate dance quality generated by our method extensively through (1) multiple quantitative metrics on physical plausibility, beat alignment, and diversity benchmarks, and more importantly, (2) a large-scale user study, demonstrating a significant improvement over previous state-of-the-art methods. Qualitative samples from our model can be found at our website.Comment: Project website: https://edge-dance.github.i

Psychometric Properties of the Altarum Consumer Engagement (ACE) Measure of Activation in Patients with Prediabetes.

BackgroundPatient activation is associated with better outcomes in chronic conditions.ObjectiveWe evaluated the psychometric properties of the 12-item Altarum Consumer Engagement™ Measure (ACE-12) in patients with prediabetes.ParticipantsACE-12 was administered to patients in the Prediabetes Informed Decisions and Education Study.Main measuresWe conducted an exploratory factor analysis followed by confirmatory factor analytic models. We evaluated item response categories using item characteristic curves. Construct validity was assessed by examining correlations of the ACE-12 scales with education, depressive symptoms, self-rated health, hemoglobin A1c, body mass index, and weight loss.Key resultsParticipants (n = 515) had a median age of 58; 56% were female; 17% Hispanic; 54% were non-White. The scree plot and Tucker and Lewis reliability coefficient (0.95) suggested three factors similar to the original scales. One item loaded on the navigation rather than the informed choice scale. Ordinal alpha coefficients for the original scales were commitment (0.75); informed choice (0.71); and navigation (0.54). ICCs indicated that one or more of the response categories for 5 of the 12 items were never most likely to be selected. Patients with lower education were less activated on the commitment (r = - 0.124, p = 0.004), choice (r = - 0.085, p = 0.009), and overall score (r = - 0.042, p = 0.011). Patients with depressive symptoms had lower commitment (r = - 0.313, p ≤ 0.001) and overall scores (r = - 0.172, p = 0.012). Patients with poorer health scored lower on the Commitment (r = - 0.308, p ≤ 0.001), Navigation (r = - 0.137, p ≤ 0.001), and overall score (r = - 0.279, p ≤ 0.001).ConclusionThe analyses provide some support for the psychometric properties of the ACE-12 in prediabetic patients. Future research evaluating this tool among patients with other chronic conditions are needed to determine whether Q1 (I spend a lot of time learning about health) should remain in the informed choice or be included in the navigation scale. Additional items may be needed to yield acceptable reliability for the navigation scale

Flebotomíneos (díptera: psychodidae) en la periferia de santarém (pa). Estratificacion horizontal y factores agravantes para la transmisión domiciliar de leishmaniosis

Phlebotominae collections were performed with CDC-type luminous traps, intradomiciliarily (dormitory) and peridomiciliarily (animal shelters) placed, triying to get breeding places in the outskirts of Santarem city in Brazil. Three outlying neighborhoods of the city, where there was registration of autochthonous cases of leishmaniasis, were chosen: Jutaí, Diamantino and St. André. 9.926 Phlebotominae individuals were captured, and they were distributed in 15 species. The most abundant species were L. longipalpis (59,72%) and L. carmelinoi (35,47%). In Jutaí neighborhood the largest amount of Phlebotominae was captured (6.031 specimens), followed by Diamantino neighborhood with (2.390 specimens) and St. André with (1.505 specimens). The major number of individuals was observed during the rainy season (5.377) than in the animal shelters (4.549). In the horizontal stratification there was a significant reduction (p = 0,02) in the Phlebotominae fauna as the residual forest increased.Fueron realizadas colectas de flebotomíneos por medio de trampas luminosas tipo CDC, colocadas intradomiciliarmente (dormitorio) y peridomiciliarmente (abrigos de animales) procurando los criaderos en barrios periféricos de la ciudad de Santarém, Brasil, haciendo la búsqueda en los lugares en donde hubiese registro de casos autóctonos de leishmaniosis, fueran seleccionadas, las siguientes áreas de trabajo: Jutaí, Diamantino y Sto. André. Se capturaron 9.926 flebotomíneos, distribuidos en 15 especies. Las especies más abundantes fueron L. longipalpis (59,72%) y L. carmelinoi (35,47%). En el barrio de Jutaí fue capturada la mayor cantidad de flebotomíneos (6.031), seguido por el barrio de Diamantino (2.390) y Sto. André (1.505). Hubo mayor densidad de individuos en los meses de la estación lluviosa. En la estratificación horizontal hubo reducción significativa (p = 0,02) de la fauna de flebotomíneos, en la medida en que aumentaba la separación de la floresta residu

Nanoestructuras de ceria-titania para fotodegradar azul de metileno con luz solar simulada

En los últimos años la protección ambiental y el uso de fuentes de energía renovables son dos objetivos principales en la investigación química. La energía solar se puede aprovechar para la degradación fotocatalítica de moléculas orgánicas contaminantes, hormonas o medicamentos, tanto en el aire, en el agua, como en las superficies, porque la luz solar es capaz de descomponerlas [1]. A pesar de la gran cantidad de aplicaciones fotocatalíticas de la titania (TiO2), fotocatalizador no tóxico, de bajo costo y muy prometedor [2], hay algunos factores críticos que limitan su fotoactividad. El principal es el valor de su salto de energía, que limita su uso como fotocatalizador en la región UV del espectro. Con el objetivo principal de extender su uso a la región visible del espectro, en literatura se ha propuesto el depósito de metales nobles en su superficie, modificaciones superficiales, así como el dopaje con iones de metales de transición o elementos de tierras raras. En este sentido, el uso de ceria (CeO2) ha atraído una gran atención debido a propiedades como su biocompatibilidad, inercia química así como su actividad en reacciones de oxidación, relacionada con la formación vacantes de oxígeno en su superficie [3]. Se ha comprobado que el sistema oxídico mixto CeO2-TiO2 es más fotoactivo que la titania pura debido a la disminución del salto de energía y a la mejora en la movilidad de los excitones. Este trabajo tiene como objetivo desarrollar fotocatalizadores basados en nanoestructuras de titania que sean activas en el visible, dopando la matriz de titania con cerio. Principalmente se pretende evaluar tanto el papel del cerio como la morfología del nanomaterial en la respuesta fotocatalítica bajo luz UV y solar.Universidad de Málaga.

The HIV/AIDS Epidemic in Miami: Perspectives of Stakeholders and Frontline Providers

Background: Miami, Florida persists as an epicenter of HIV/AIDS nationally and has been more delayed than other areas with high HIV burden in implementing public health measures that mitigate transmission risk. These issues among other social and structural-level determinants have complicated progress in addressing HIV/AIDS in Miami. Purpose: The stagnated progress in improving HIV outcomes in Miami necessitated a more comprehensive understanding of the experiences and insights of stakeholders within the system. We used a stakeholder analysis approach to understand the complexity of driving factors and key challenges facing this HIV epidemic. Methods: A stakeholder analysis was conducted through 11 focus groups (64 participants) with front line workers working in non-profit, community-based agencies in Miami. The interview guide was designed to elicit a broad discussion on the social and intermediary determinants of HIV/AIDS, as well as the context surrounding barriers to treatment. Data were analyzed using qualitative software for thematic analysis. Results: Participants highlighted particular populations vulnerable to HIV/AIDS and insufficiently engaged in treatment, including immigrants and people who use drugs. Stigma surrounding HIV/AIDS as well as sexual orientation, mental health, and drug use was a noted persisting barrier. Participants expressed needs for more targeted outreach and education for both prevention and treatment. Numerous systemic gaps were identified as barriers to treatment engagement and retention. Other comorbidities and socioeconomic challenges, including criminal justice histories, housing instability and low educational attainment, also hamper HIV/AIDS management. Discussion: Through these discussions with stakeholders representing a diversity of voices, findings can inform comprehensive and coordinated strategies for curbing the HIV/AIDS epidemic in Miami. The development of prevention and treatment interventions should consider cultural contexts of health behaviors, multi-level stigma related to HIV/AIDS and other comorbid and socioeconomic challenges, and increased implementation of harm reduction programs such as PrEP delivery and syringe exchange programs

The Carnegie Supernova Project I: photometry data release of low-redshift stripped-envelope supernovae

The first phase of the Carnegie Supernova Project (CSP-I) was a dedicated supernova follow-up program based at the Las Campanas Observatory that collected science data of young, low-redshift supernovae between 2004 and 2009. Presented in this paper is the CSP-I photometric data release of low-redshift stripped-envelope core-collapse supernovae. The data consist of optical (uBgVri) photometry of 34 objects, with a subset of 26 having near-infrared (YJH) photometry. Twenty objects have optical pre-maximum coverage with a subset of 12 beginning at least five days prior to the epoch of B-band maximum brightness. In the near-infrared, 17 objects have pre-maximum observations with a subset of 14 beginning at least five days prior to the epoch of J-band maximum brightness. Analysis of this photometric data release is presented in companion papers focusing on techniques to estimate host-galaxy extinction (Stritzinger et al., submitted) and the light-curve and progenitor star properties of the sample (Taddia et al., submitted). The analysis of an accompanying visual-wavelength spectroscopy sample of ~150 spectra will be the subject of a future paper.Comment: Updated a couple of small error

Estimation of the specific enthalpy–temperature functions for plastering mortars containing hybrid mixes of phase change materials

The use of phase change materials (PCMs) for the building sector is increasingly attracting attention from researchers and practitioners. Several research studies forwarded the possibility of incorporating microencapsulated PCM in plastering mortars for building facades, in pursuit of increased energy efficiency associated with the heat storage capacity of PCM. However, most of these studies are centred in the use of a single type of PCM, which is bound to be more adequate for a given season of the year (e.g. winter or summer) than for all the seasons. The study proposed in this work regards the evaluation of the possibility of using more than one kind of PCM, with distinct melting ranges, here termed as hybrid PCMs, in plastering mortars, to achieve adequately advantageous performance in all seasons of the year. To characterize the PCM, the specific enthalpy and phase change temperature should be adequately measured. The main purpose of this study was to show the conceptual feasibility of combining PCMs in mortars and to evaluate the behaviour of the resulting mortars with differential scanning calorimeter. The results showed that the behaviour of the mortar that contains more than one type of PCM can be predicted through the superposition of effects of the independent PCMs and no interaction occurs between them. The knowledge obtained from the experimental testing established bases for a framework of numerical simulation of real-scale applications, which can be used to ascertain the feasibility of the hybrid PCM concept for decreases in energy consumption of heating/cooling demands in the buildings.Fundação para a Ciência e a Tecnologia (FCT

Photocatalytic Activity of Composites for Ethylene Degradation Under UV-A and Visible Light

Ethylene is a natural hormone responsible for many processes, including ripening. One way to extend the shelf life of several fruits and vegetables is to remove ethylene from the atmosphere of storage and transport, for which photocatalysis processes can be an efficient technology. In this study, we investigated the ethylene photodegradation of four different composites (Cu/C3N4, Cu/TiO2, Ni/C3N4, Ni/TiO2) under UV-A and visible illumination. The photocatalytic composites were characterized, and the photocatalytic assay was performed in a continuous system for 1 h (ethylene concentration at 1.0 % in synthetic air, 50 mL.min-1, and 400 mg of photocatalyst). The results indicated that the Cu/C3N4 sample did not produce carbon dioxide under visible light or UV-A illumination, so ethylene was not degraded. The Ni/TiO2 sample had the best performance for ethylene degradation under visible light and UV-A illumination, showing higher CO2 production with UV-A. After illumination for 1 h, the light was turned off, and 5 min later, the CO2 concentration at the outlet was equal to the initial. Thus, the composites Ni/C3N4, Cu/TiO2, and Ni/TiO2 proved to be efficient in ethylene degradation. Therefore, they can increase the shelf life of fruits and vegetables, using photocatalysis to remove ethylene from the atmosphere while storing and transporting these foods

Adsorption of CO2 on Amine-Grafted Activated Carbon

Adsorption on amine-grafted materials may be a potentially attractive alternative to capturing CO2 from power plants. Activated Carbon (AC) has been proposed as a potential adsorbent due to its natural affinity for CO2 and to the possibility of tailoring textural properties and surface chemistry to enhance capacity and selectivity. An AC commercial sample was functionalized with monoethanolamine (MEA) in order to obtain nitrogen-enriched AC with two different loadings (ACN10 and ACN20). Samples characterization was carried out by nitrogen adsorption/desorption isotherms at 77 K, XPS, FTIR and adsorption microcalorimetry. CO2 equilibrium adsorption experiments were accomplished in a volumetric system in the pressure range of vacuum up to 10 bar, at 298 and 348 K. Impregnated activated carbon presented different chemical and textural characteristics with a significant reduction in the surface area, depending on the amine loading. A high adsorption capacity at room temperature and high pressure was observed for the pristine AC as compared to the modified samples. The reduction in surface area affected the adsorption capacity of CO2 at 298 and 348 K, except for adsorption on ACN10 at 348 K, which suggests the occurrence of chemisorption.Fil: Bezerra, Diôgo P..
