Geometric distances between closed universes

The large-scale structure of the Universe is well approximated by the Friedmann equations, parametrized by several energy densities which can be observationally inferred. A natural question to ask is: How different would the Universe be if these densities took on other values? While there are many ways this can be approached depending on interpretation and mathematical rigor, we attempt an answer by building a “history space” of different cosmologies. A metric is introduced after overcoming technical hurdles related to Lorentzian signature and infinite volume, at least for topologically closed cases. Geodesics connecting two points on the superspace are computed to express how distant—in a purely geometric sense—two universes are. Age can be treated as a free parameter in such an approach, leading to a more general mathematical construct relative to geometrodynamical configuration space. Connections to bubble inflation and phase transitions are explored.Support provided by the Conselleria d’Educació, Cultura, Universitats i Ocupació de la Generalitat Valenciana through Prometeo Project CIPROM/2022/13 is gratefully acknowledged

El sobreseimiento en la fase intermedia del proceso de responsabilidad penal de los menores

En la denominada fase intermedia de la LORPM, una vez presentado el escrito de alegaciones de la defensa, el Juez de Menores deberá resolver sobre la apertura o no de la audiencia. Entre las decisiones que éste puede adoptar se encuentra la del sobreseimiento motivado de las actuaciones. En el presente trabajo queremos aclarar que los únicos motivos en los que el Juez de Menores podrá dictar auto de sobreseimiento en esta fase intermedia son los establecidos específicamente en la LORPM y el establecido en el art. 637.2 LECrim., para el caso de que, en este último caso, se formulen alegaciones por parte de las acusaciones

In Presence ATLAS

The UNIVERSITY of Universities (UOU) is an international network of academics from European schools of architecture, collaborating to provide online workshops throughout the academic year for students from different universities who work together remotely and in a collaborative way. This section of the Atlas shows the work carried out by graduate and undergraduate students in a three-week workshop on the theme of the relationship between body and space. The proposed theme-summarised in the title "Acting/Acted Bodies in the Architectural and Urban Spaces"-asked students to develop an approach from the personal to the collective (or from the particular to the general), starting from their own body and the relationship it establishes with the spaces of their everyday life, to understand critical issues and opportunities and develop scenarios of design transformation at different scales

Prediction of Metastasis in Paragangliomas and Pheochromocytomas Using Machine Learning Models: Explainability Challenges

One of the main issues with paragangliomas and pheochromocytomas is that these tumors have up to a 20% rate of metastatic disease, which cannot be reliably predicted. While machine learning models hold great promise for enhancing predictive accuracy, their often opaque nature limits trust and adoption in critical fields such as healthcare. Understanding the factors driving predictions is essential not only for validating their reliability but also for enabling their integration into clinical decision-making. In this paper, we propose an architecture that combines data mining, machine learning, and explainability techniques to improve predictions of metastatic disease in these types of cancer and enhance trust in the models. A wide variety of algorithms have been applied for the development of predictive models, with a focus on interpreting their outputs to support clinical insights. Our methodology involves a comprehensive preprocessing phase to prepare the data, followed by the application of classification algorithms. Explainability techniques were integrated to provide insights into the key factors driving predictions. Additionally, a feature selection process was performed to identify the most influential variables and explore how their inclusion affects model performance. The best-performing algorithm, Random Forest, achieved an accuracy of 96.3%, precision of 96.5%, and AUC of 0.963, among other metrics, combining strong predictive capability with explainability that fosters trust in clinical applications

Direct embodied water management for sustainable construction: a case of India

Growing concerns surrounding water scarcity have spiked an interest in Embodied Water (EW) studies globally. The EW of a building is the amount of water needed to manufacture all the materials that constitute the building (Indirect EW) plus the amount of water needed to construct that building (Direct EW). For a building with an operational period of 50 years, this EW can constitute between 20-40% of the total building water footprint. This huge contribution of EW in the total building water footprint signifies the urgent need for its management. The research presented in this paper will explore the Direct EW through case studies of reinforced concrete (RC) frame residential buildings located in India as they constitute 45% of the constructed Indian floor space. An explanatory mixed-method research design that comprises of a quantitative design followed by a qualitative design is adopted. The quantitative research design uses document analysis to determine the amount of water consumed for the execution of different construction activities during the construction of these case study buildings. The qualitative research design uses semi-structured interviews with seven construction professionals involved during the construction of these case study buildings and working on different residential building construction projects in India to determine the water management practices adopted on construction sites in India and the challenges encountered for their implementation. The document analysis revealed that for multi-storied RC frame construction, the Direct EW is in the range of 0.32-0.35 kL/m2 with curing activities contributing between 35-45%. The semi-structured interview analysis revealed that application of efficient water management practices on construction sites like covering freshly poured concrete with moist gunny bags and the integration of cleaning platforms can help reduce Direct EW by almost 10%. With the building industry projected to continue growing, along with worldwide water scarcity, managing and saving Direct EW can help conserve the diminishing water resources

Effects of Algae-Based Supplementation on Metabolic, Oxidative, and Inflammatory Markers in Physically Active Adults: A Pilot Randomized Controlled Trial

Algae-based supplements are gaining attention for their potential metabolic, antioxidant, and anti-inflammatory properties in sports nutrition. Methods: A 30-day pilot randomized controlled trial was conducted in 70 healthy male athletes (mean age 25.4 ± 4.9 years) from competitive soccer and handball teams. Participants were randomly assigned to a supplementation group (6 g/day of Ulva-derived algae powder) or a control group. Both groups followed identical training routines and adhered to standardized nutritional recommendations, including macronutrient distribution and permitted supplements (e.g., isotonic drinks, protein shakes). Biochemical markers analyzed at baseline and post-intervention included HbA1c, lipid profile, malondialdehyde (MDA), catalase, myeloperoxidase (MPO), erythrocyte sedimentation rate (ESR), and cortisol. Genetic polymorphisms related to metabolic traits were also assessed. Results: Significant group × time interactions (p < 0.001) were observed for HbA1c, LDL, triglycerides, MDA, MPO, ESR, and cortisol, all of which improved in the algae-supplemented group. Correlation analysis revealed associations between HbA1c and LDL/TG as well as between cortisol and MPO. No significant genetic modulation of responses was detected, although a trend was noted for cortisol variation and insulin resistance risk. Conclusions: Algae-based supplementation led to favorable metabolic, oxidative, and inflammatory changes. These findings suggest its potential utility as a nutritional strategy to support recovery in athletes during periods of high training load or competition.This work was supported by the “Activa Startups” program, funded by the Spanish Ministry of Industry, Trade and Tourism (MINCOTUR) and the Fundación EOI, F.S.P., within the framework of the Recovery, Transformation and Resilience Plan of the Government of Spain (Component 13, Investment 2, Action C13.I2.2.4)
