• An open-source co-simulation framework (ASDELSOL) was applied to optimize retrofitted CSP/PV/eTES plant operation using real market pricess. • The techno-economic impact of PV ratio, electric heater capacity and auxiliary tank volume was quantified for three hybrid configurations. • Electric heaters and auxiliary storage enhance flexibility, but their CAPEX limits NPV gains within a 12-year horizon. This study evaluates the techno-economic viability of retrofitting Concentrated Solar Power (CSP) plants with Photovoltaics (PV) and Electric Thermal Energy Storage (eTES)—thermal storage charged via electric heaters—to enhance dispatchability and profitability under current market conditions. Using the dynamic tool ASDELSOL, a predictive control strategy combines daily solar-resource classification with hourly electricity-price segmentation. Three configurations are assessed: (1) CSP + PV; (2) CSP + PV with a direct electric heater to TES; and (3) CSP + PV with an electric heater feeding an auxiliary thermal tank. In Scenario 1, baseload operation is benchmarked against price-driven optimization; the latter raises Net Present Value (NPV) across all PV ratios, peaking at €36.86 M for 25% PV. Scenarios 2–3 are analyzed under economic optimization, quantifying the influence of heater sizing and auxiliary-tank volume. While these components increase operational flexibility, their added cost does not pay back within 12 years; extending the investment horizon shifts the optimum toward higher PV ratios and improves the appeal of more integrated layouts. Overall, CSP–PV retrofits operated with market-responsive control are cost-effective, and adding electric heaters plus auxiliary storage can yield additional value under favorable market and investment assumptions.

La obra que aqu recensionamos y que se publica bajo el ttulo "La autonoma de la voluntad en el mbito matrimonial y de las parejas de hecho: perspectivas interna, internacional y comparada" es fruto del proyecto estatal de I+D+i "Retos de la regulacin jurdico-patrimonial del matrimonio y de otras realidades (uniones de hecho) en los planos supraestatal y estatal (REJURPAT)".El trabajo completa una triloga publicada bajo el amparo del referido proyecto, viniendo, pues, precedido de la publicacin de otras dos obras dedicas al estudio del mbito patrimonial, no solo del matrimonio, sino de esa otra realidad familiar existente en la actualidad como son las parejas de hecho: "Rgimen patrimonial de las uniones registradas: aspectos estatales y supraestatales (a propsito del Reglamento UE 2016/1104)" y "Rgimen econmico matrimonial: cuestiones de Derecho interno, comparado e internacional".La calidad de la publicacin colectiva no solo viene justificada por los autores que la han hecho posible, y a los que a continuacin nos referiremos, sino por la solvencia acadmica de quienes la dirigen, los profesores Andrs Rodrguez Benot y Csar Hornero Mndez, y la coordinacin de Laura Garca lvarez, un ptimo aval acadmico de que el contenido de los diferentes captulos nos aportarn nuevas ideas y propuestas fruto de investigaciones serias, rigurosas e innovadoras -caractersticas que, por lo general, y desgraciadamente, cada vez son ms "

Abstract Purpose Stress-related disorders are increasingly prevalent in modern societies and represent a major public mental health concern, particularly in academic environments. While stress is an adaptive response, chronic exposure is associated with psychological distress, impaired well-being, and physiological dysregulation. Non-pharmacological interventions such as heart rate variability biofeedback, interoceptive training, and mindfulness-based programs have shown promise in stress reduction, yet few studies have compared these approaches within a single population using both subjective and objective outcomes. The BIMSTRESS study aims to evaluate the effectiveness of these three interventions in reducing perceived stress in a university population and to explore individual differences in intervention response using psychophysiological and neurophysiological markers. Methods BIMSTRESS is a longitudinal, four-arm, randomized, wait-list controlled trial conducted in a Spanish university community, including students, teaching staff, and administrative personnel. Participants are randomly allocated to heart rate variability biofeedback, interoceptive training, mindfulness-based intervention, or wait-list control. Interventions are delivered over six weeks using a hybrid format that combines weekly laboratory sessions with home-based practice. Assessments are conducted at baseline and post-intervention (7 weeks). The primary outcome is change in perceived stress. Secondary outcomes include psychological well-being, mindfulness, affect, cognitive performance, and physiological measures of stress regulation, including heart rate variability and quantitative electroencephalography. Conclusion The BIMSTRESS study will provide evidence on the comparative effectiveness of scalable, non-invasive stress-reduction interventions in a university setting and will contribute to understanding the role of physiological and neurophysiological markers as potential moderators and mediators of intervention response, informing personalized and preventive approaches to mental health promotion.
