Data base of manuscript "Clinical and Psychosocial Predictors of Physical Activity in Systemic Lupus Erythematosus: a Multicentre Cross-Sectional Study", Background/Objectives: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterised by musculoskeletal manifestations such as myopathies, arthritis, and arthralgia. Physical activity may improve patients’ perceived quality of life and over-all wellbeing. The objective was to assess physical activity levels in patients with SLE and to identify the main clinical, sociodemographic, and anthropometric variables influencing these levels. Methods: A multicentre cross-sectional study was conducted including 64 patients with SLE. Clinical variables were extracted from medical records, while pa-tient-reported outcomes were collected at the survey. The dependent variable was physical activity, assessed with the International Physical Activity Questionnaire. Independent variables included fatigue (FAS), quality of life (SF-36), sleep (PSQI), depression (BDI-II), anxiety (HARS), age, disease factors (activity, duration, damage), sex, smoking, and comorbidities. Results: Significant associations were observed between physical activity levels and smoking status (χ²=11.88; p=0.003), sleep quality (χ²=6.81; p=0.03), and anxiety (χ²=18.39; p=0.001). In multivariable analyses, poor sleep (PSQI>5) (OR=14.40; 95% CI: 2.50–82.99), higher anxiety (HARS; per point OR=1.12; 95% CI: 1.05–1.20), and higher SF-36 Physical Component Summary (PCS) scores (per point OR=1.29; 95% CI: 1.15–1.45) were associated with being in a higher physical activity category. Given the counterintui-tive direction for sleep and the limited model fit, these findings should be interpreted cau-tiously. Conclusions: In patients with SLE, physical activity was associated with smoking, sleep disturbances, and anxiety. Strongest associations were observed for sleep quality, anxiety, and physical health, although results require validation in larger, diverse cohorts, particularly regarding sleep–activity links.

This dataset contains information obtained during the design and experimental validation of a dual-band, dual-mode, circularly polarized antenna implemented in fully-woven textile technology, with capability for Simultaneous Wireless Information and Power Transfer (SWIPT)., This research was funded by AGENCIA ESTATAL DE INVESTIGACIÓN-GOBIERNO DE ESPAÑA, under grants number PID2021-126301NA-I00 and EQC2019-005768-P, by GOBIERNO DEL PRINCIPADO DE ASTURIAS, under grants number IDE/2024/0007693, AYUD/2021/51706, and IDI/2021/000207, and by UNIVERSIDAD DE OVIEDO under grant number GR-2010-0015.

El proyecto SALMAFood aborda uno de los grandes retos contemporáneos a los que se enfrenta la alimentación en las sociedades actuales: la transformación hacia sistemas alimentarios más saludables, sostenibles y justos. A través de un enfoque interdisciplinar y multiactor, el equipo de investigación ha analizado el malestar ciudadano con la alimentación, los desafíos del sistema agroalimentario español y las propuestas de mejora impulsadas desde distintos sectores sociales. Los resultados de esta investigación permiten confirmar donde se encuentra los focos del malestar de la ciudadanía con el sistema alimentario y también se ha visibilizado el bienestar que produce la preparación y el consumo alimentario. Esta dualidad ha sido posible al plantear un avance metodológico en el análisis del sistema alimentario, en el que se ha trabajado sobre los eslabones tradicionales (producción, industria, distribución y consumo) pero se ha añadido como elementos del sistema la preparación de los alimentos y la comensalidad, incorporando el hogar como espacio de análisis sobre la alimentación., Base de datos de la encuesta realizada a la población española sobre las percepciones y valoraciones sobre el sistema alimentario., Ministerio de Ciencia innovación y universidades.

The Asymmetric Double Cantilever Beam (ADCB) is a common test configuration used to produce mixed mode I/II in composite materials. It consists of two sublaminates with different thicknesses or elastic properties, a situation that usually occurs in bimaterial adhesive joints. During this test, the sample undergoes rotation. In this work, the influence of this rotation on the calculation of the energy release rate (ERR) in modes I and II was studied using the Finite Element Method (FEM). Several models with different degrees of asymmetry (different thickness ratio and/or elastic modulus ratio) and different applied displacements were prepared to obtain different levels of rotation during the test. As is known, the concept of modes I and II refers to the components of the energy release rate calculated in the direction perpendicular and tangential to the delamination plane, respectively. If the model experiences significant rotation during the application of the load, this non-linearity must be considered in the calculation of the mode partition I/II. In this work, appreciable differences were observed in the values of modes I and II, depending on their calculation in a global system or a local system that rotates with the sample. When performing crack growth calculations, the difference between critical loads can be in the order of 4%, while the difference between mode I and mode II results can reach 4% and 14%, respectively, for an applied displacement of only 5 mm. Currently, this correction is not usually implemented in Finite Element calculation codes or in analytical developments. The purpose of this article is to draw attention to this aspect when the rotation of the specimen is not negligible., This research received no external funding.

Phonetic annotations at 10 levels in PRAAT were carried out on a corpus of 40 Spanish poetry reading recordings by the following authors: Rafael Alberti (3), Vicente Aleixandre (3), Dámaso Alonso (3), Clementina Arderiu (3), Luis Cernuda (3), Ernestina de Champourcín (3), Carmen Conde (3), Ángela Figuera (2), Gloria Fuertes (2), Jaime Gil de Biedma (3), Ángel González (3), Miguel Hernández (1), Juan Ramón Jiménez (3), Luis Rosales (2), and Pedro Salinas (3). The annotation model (VIP-VSP-Radar) is based on Colonna, V. (2022). "Voices of Italian Poets: Storia e analisi fonetica della lettura della poesia italiana del Novecento". Dell’Orso, and was designed for semi-automatic data extraction through Colonna, V. & Román Montes de Oca, D. (2024). "VIP-VSP-Radar Data Extraction for Poem Phonetic Analysis".
