A systematic review of wearable biosensor usage in immersive virtual reality experiences
Wearable biosensors are increasingly incorporated in immersive Virtual Reality (iVR) applications. A trend that is attributed to the availability of better quality, less costly, and easier-to-use devices. However, consensus is yet to emerge over the most optimal combinations. In this review, the aim is to clarify the best examples of biosensor usage in combination with iVR applications. The high number of papers in the review (560) were classified into the following seven fields of application: psychology, medicine, sports, education, ergonomics, military, and tourism and marketing. The use of each type of wearable biosensor and Head-Mounted Display was analyzed for each field of application. Then, the development of the iVR application is analyzed according to its goals, user interaction levels, and the possibility of adapting the iVR environment to biosensor feedback. Finally, the evaluation of the iVR experience was studied, considering such issues as sample size, the presence of a control group, and post-assessment routines. A working method through which the most common solutions, the best practices, and the most promising trends in biofeedback-based iVR applications were identified for each field of application. Besides, guidelines oriented towards good practice are proposed for the development of future iVR with biofeedback applications. The results of this review suggest that the use of biosensors within iVR environments need to be standardized in some fields of application, especially when considering the adaptation of the iVR experience to real-time biosignals to improve user performance.Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature.

Rhamnogalacturonan–I pectin and derived oligosaccharides obtained from sugar beet pulp and discarded red beetroot: Characterization and comparative study of their antioxidant and prebiotic properties
Rhamnogalacturonan–I (RG–I) pectin recovered from sugar beet pulp (SBP) and discarded red beetroot (DRB) were subjected to enzymatic hydrolysis to obtain pectooligosaccharides (POS). The hydrolysates with the highest amount of oligomer with a degree of polymerization from 2 to 6 were selected for a detailed characterization of the composition and the structure by MALDI-TOF MS and 1H NMR. The yields of pectin and POS products ranged from 32.7% (g DRB POS/g DRB) to 37.0% (g SBP Pectin/g SBP) with the POS content from 64.4% (DRB products) to 68.7% (SBP POS). A comparative study was conducted between SBP Pectin, SBP POS, DRB Pectin, DRB POS, and commercial prebiotics (inulin and fructooligosaccharides) for their antioxidant capacity and prebiotic potential. The results revealed the much higher antioxidant capacity of DRB products (DPPH: 176.8 μmol Trolox equivalent/g pectin and 162.5 μmol Trolox equivalent/g POS) over the other products. Both bacteria strains evaluated grew with all substrate products. DRB POS and inulin exhibited the highest maximum growth rate for Lactobacillus rhamnosus (0.25 and 0.26 h−1, respectively), whereas Bifidobacteria longum grew faster on DRB Pectin (0.89 h−1). The short chain fatty acids and lactate production were also measured. Highest concentrations arose using SBP products as substrates (125.3 mM for pectin and 115.7 mM for POS with Lactobacillus rhamnosus and 87.8 mM for pectin and 95.0 mM for POS with Bifidobacterium longum). The results demonstrated the potential applications of SBP and especially DRB products in the food industry due to their high antioxidant and prebiotic properties.The authors acknowledge the financial support from the Spanish Ministry of Science and Innovation (project PID 2020-115110RB-I00/AEI/10.13039/501100011033).

Explicit implementation of hydrogen transport in metals
Hydrogen embrittlement prediction demands a numerical framework coupling a damage model with local hydrogen concentration. The inherent nonlinearity in hydrogen-stress-damage interactions challenges convergence in implicit schemes. To address this limitation, we propose a novel chemical potential-based explicit formulation for simulating hydrogen transport in metals. Our approach exploits a heat transfer analogy, linking mechanical and hydrogen transport via inelastic energy as a heat source. By employing chemical potential rather than lattice concentration, our method eliminates the need for user-defined boundary conditions and hydrostatic stress gradient determination. We integrate a VUMATHT subroutine for diffusion modelling and a VUMAT subroutine for material behaviour, coupling stress and strain rates as a heat source for diffusion. Validating against a classical benchmark, we compare our explicit approach with hydrogen concentration-based methods in ABAQUS Standard and Comsol Multiphysics. Stability conditions are assessed for different mesh sizes and mass scaling densities and the capabilities of our approach are showcased for 3D simulations of notched tensile specimens. Our framework offers a novel and efficient pathway for integrating hydrogen transport with user-defined material behaviour, promising advancements in hydrogen-informed damage models.The authors gratefully acknowledge funding from projects PID2021-124768OB-C21 and TED2021-130413B-I00.

Integrative models of Education for Citizenship (Handbook) - 2nd edition
Desarrollar una ciudadanía activa es esencial para alcanzar una participación social bajo principios como el respeto mutuo y la no violencia, de acuerdo con los derechos humanos. Nuestra sociedad necesita formar personas con capacidad de decisión y pensamiento crítico para afrontar los problemas actuales. Esta segunda edición del manual completa a la primera con algunas modificaciones del capítulo de matemáticas e incluye un nuevo capítulo sobre el papel de la Educación Física en los modelos integrados. De esta manera, el manual ofrece a los lectores una perspectiva más global sobre qué son los modelos integrados de educación, apostando por dirigir los esfuerzos hacia un concepto de educación más inclusivo y acercando a los profesionales de la educación al concepto de ciudadanía activa y su aplicación en el aula. La experiencia de la primera edición nos ha demostrado que este manual supone un magnífico punto de partida para desarrollar alternativas innovadoras de educación con matices de aquellas competencias que nuestra sociedad actual demanda con fuerza.Este manual ha sido elaborado bajo los auspicios de la Cátedra de Derechos Humanos y Cultura Democrática de la Universidad de Burgos., Este trabajo ha sido cofinanciado por el programa Erasmus de la Unión Europea
