Publicación A Take Home Laboratory to Support Teaching Electronics: Instructors Perspectives and Technical Revisions, Journal on Teaching Engineering(University of Porto, 2024-12-02) O´Mahony, Tom; Murray, Michael; Hill, Martin; Onet, Raul; Neag Marius; Torre Cubillo, Luis de la; Zhou, DaoThree modes dominate engineering labs – in-person, simulation and remote. Take-home laboratories have received comparatively little attention within engineering education. This article reports on qualitative data that was collected, via focus groups with eight staff from a single University, to evaluate the effectiveness of take-home laboratories. The laboratories consisted of a range of embedded development platforms along with a bespoke Home Electronics Laboratory Platform (HELP) that was designed to support the learning of analog and digital electronics in the early years of our programmes. The findings indicate that take-home laboratories can support the development of independent learners and enhance troubleshooting skills. Participants also identified that supporting students in their troubleshooting activity was particularly challenging in a remote environment. We make some suggestions for how take-home laboratories could be used to complement existing laboratory practices.Publicación Epigenetic Mechanisms in Aging: Extrinsic Factors and Gut Microbiome(MDPI, 2024-12-14) Borrego Ruiz, Alejandro; Borrego, Juan J.Background/Objectives: Aging is a natural physiological process involving biological and genetic pathways. Growing evidence suggests that alterations in the epigenome during aging result in transcriptional changes, which play a significant role in the onset of age-related diseases, including cancer, cardiovascular disease, diabetes, and neurodegenerative disorders. For this reason, the epigenetic alterations in aging and age-related diseases have been reviewed, and the major extrinsic factors influencing these epigenetic alterations have been identified. In addition, the role of the gut microbiome and its metabolites as epigenetic modifiers has been addressed. Results: Long-term exposure to extrinsic factors such as air pollution, diet, drug use, environmental chemicals, microbial infections, physical activity, radiation, and stress provoke epigenetic changes in the host through several endocrine and immune pathways, potentially accelerating the aging process. Diverse studies have reported that the gut microbiome plays a critical role in regulating brain cell functions through DNA methylation and histone modifications. The interaction between genes and the gut microbiome serves as a source of adaptive variation, contributing to phenotypic plasticity. However, the molecular mechanisms and signaling pathways driving this process are still not fully understood. Conclusions: Extrinsic factors are potential inducers of epigenetic alterations, which may have important implications for longevity. The gut microbiome serves as an epigenetic effector influencing host gene expression through histone and DNA modifications, while bidirectional interactions with the host and the underexplored roles of microbial metabolites and non-bacterial microorganisms such as fungi and viruses highlight the need for further research.Publicación Unraveling internal friction in a coarse-grained protein model(AIP Publishing, 2025-03-19) Monago Díaz, Carlos Sebastián; Torre Rodríguez, Jaime Arturo de la; Delgado-Buscalioni, RafaelUnderstanding the dynamic behavior of complex biomolecules requires simplified models that not only make computations feasible but also reveal fundamental mechanisms. Coarse-graining (CG) achieves this by grouping atoms into beads, whose stochastic dynamics can be derived using the Mori–Zwanzig formalism, capturing both reversible and irreversible interactions. In liquid, the dissipative bead–bead interactions have so far been restricted to hydrodynamic couplings. However, friction does not only arise from the solvent but, notably, from the internal degrees of freedom missing in the CG beads. This leads to an additional “internal friction” whose relevance is studied in this contribution. By comparing with all-atom molecular dynamics (MD), we neatly show that in order to accurately reproduce the dynamics of a globular protein in water using a CG model, not only a precise determination of elastic couplings and the Stokesian self-friction of each bead is required. Critically, the inclusion of internal friction between beads is also necessary for a faithful representation of protein dynamics. We propose to optimize the parameters of the CG model through a self-averaging method that integrates the CG dynamics with an evolution equation for the CG parameters. This approach ensures that selected quantities, such as the radial distribution function and the time correlation of bead velocities, match the corresponding MD values.Publicación Internal dissipation in the Dzhanibekov effect(Elsevier, 0001-08-20) Torre Rodríguez, Jaime Arturo de la; Español Garrigos, JoséThe Dzhanibekov effect is the phenomenon by which triaxial objects like a spinning wing bolt may continuously flip their rotational axis when initially spinning around the intermediate axis of inertia. This effect is closely related to the Tennis Racket theorem that establishes that the intermediate axis of inertia is unstable. Over time, however, dissipation ensures that a torque free spinning body will eventually rotate around its major axis, in a process called precession relaxation, which counteracts the Dzhanibekov effect. Euler’s equations for a rigid body effectively describe the Dzhanibekov effect, but cannot account for the precession relaxation effect. A dissipative generalization of Euler’s equations displays two dissipative mechanisms: orientational diffusion and viscoelasticity. Here we show through numerical simulations of the dissipative Euler’s equations that orientational diffusion, rather than viscoelasticity, primarily drives precession relaxation and effectively suppresses the Dzhanibekov effect.Publicación Stochastic Dissipative Euler’s equations for a free body(De Gruyter Brill, 2024-11-05) Torre Rodríguez, Jaime Arturo de la; Sánchez Rodríguez, Jesús; Español Garrigos, JoséIntrinsic thermal fluctuations within a real solid challenge the rigid body assumption that is central to Euler’s equations for the motion of a free body. Recently, we have introduced a dissipative and stochastic version of Euler’s equations in a thermodynamically consistent way (European Journal of Mechanics – A/Solids 103, 105,184 (2024)). This framework describes the evolution of both orientation and shape of a free body, incorporating internal thermal fluctuations and their concomitant dissipative mechanisms. In the present work, we demonstrate that, in the absence of angular momentum, the theory predicts that the principal axes unit vectors of a body undergo an anisotropic Brownian motion on the unit sphere, with the anisotropy arising from the body’s varying moments of inertia. The resulting equilibrium time correlation function of the principal eigenvectors decays exponentially. This theoretical prediction is confirmed in molecular dynamics simulations of small bodies. The comparison of theory and equilibrium MD simulations allow us to measure the orientational diffusion tensor. We then use this information in the Stochastic Dissipative Euler’s Equations, to describe a non-equilibrium situation of a body spinning around the unstable intermediate axis. The agreement between theory and simulations is excellent, offering a validation of the theoretical frameworkPublicación La interpretación constitucional como caso especial de la interpretación jurídica(Universidad Carlos III de Madrid, 2023-03-30) Portocarrero Quispe, Jorge AlexanderInterpretación jurídica e interpretación constitucional son dos de los temas sobre los que más se ha escrito e investigado en los últimos años en el ámbito de la teoría jurídica. Sin embargo, no parece claro si estas categorías son equivalentes o si, en alguna medida, existe una diferencia o cualificación entre ellas ¿Interpretar normas constitucionales es indistinguible de la interpretación de normas infra constitucionales? ¿Son los métodos de aplicación para normas legales los mismos que aquellos a ser empleados para aplicar normas constitucionales? Mientras que algunas teorías equiparan la interpretación de normas constitucionales a la interpretación de normas legales, otras teorías plantean desarrollar una metodología de interpretación propia para las normas constitucionales. La importancia de abordar la relación entre interpretación jurídica e interpretación constitucional radica en que, si la interpretación constitucional se diferencia de la interpretación jurídica en general, entonces será posible sostener que la metodología tradicional, basada en cánones de interpretación y la subsunción, es insuficiente para interpretar la constitución. El presente artículo busca estructurar un argumento en favor de la especialidad de la interpretación constitucional, sin que ello implique desvincularla totalmente de la teoría general de la interpretación jurídica.Publicación Restricciones a la independencia judicial en el Perú: análisis del caso Cuya Lavy y otros vs. Perú de la corte interamericana de derechos humanos(UNED - Universidad Nacional de Educación a Distancia, 2023-07-14) Portocarrero Quispe, Jorge AlexanderLa Sentencia del Caso Cuya Lavy y otros Vs. Perú (en adelante la Sentencia Cuya Lavy) de la Corte Interamericana de Derechos Humanos (en adelante la Corte IDH) representa el último estadio en la evolución de la jurisprudencia de dicha Corte respecto del procedimiento de evaluación y ratificación periódica de jueces y fiscales en el Perú. A nivel interamericano, la Sentencia Cuya Lavy sienta por primera vez un precedente claro sobre los estándares mínimos que ha de satisfacer cualquier tipo de restricción al principio de la independencia judicial en el marco de la Convención Americana de Derechos Humanos (en adelante la Convención Americana); por lo que los estándares establecidos en esta sentencia no solo son aplicables al Perú, sino que lo son para todo Estado miembro que busque restringir en alguna medida el principio de independencia judicial en su derecho interno. Por otro lado, a nivel del derecho nacional, la Corte IDH en la Sentencia Cuya Lavy impone al Estado peruano, como medida de no repetición, la obligación de realizar adecuaciones normativas concretas para el aseguramiento de la independencia judicial; medida que obliga al Perú no solo a modificar su legislación sobre el proceso de evaluación y ratificación periódica de jueces y fiscales, sino que además implica una modificación de las normas constitucionales que legitiman dicho procedimiento. Si bien el procedimiento de la ratificación periódica de jueces y fiscales, tal y como está planteado en la Constitución peruana, mutatis mutandis, tiene parangón en el derecho comparado, sí es un caso bastante particular y con más de un siglo de tradición en la historia constitucional peruana. El presente artículo busca analizar en qué medida el principio independencia judicial es compatible con el procedimiento de la ratificación periódica de jueces y fiscales en el marco del ordenamiento jurídico peruano y el sistema interamericano de derechos humanos. Para tal fin, se recurrirá a los argumentos planteados por la Corte Interamericana de Derechos Humanos en la Sentencia del Caso Cuya Lavy y otros Vs. Perú, sometiéndolos a un análisis descriptivo-valorativo en el contexto del derecho interno peruano.Publicación Un modelo de interpretación para la efectivización progresiva de derechos sociales de prestación(Universidad Externado de Colombia, 2024-05) Portocarrero Quispe, Jorge AlexanderEl presente artículo aborda, desde una perspectiva teórica, la problemática de la efectivización de los derechos sociales de prestación. La tesis central del artículo sostiene que esta efectivización puede darse mediante un modelo progresivo de tres niveles, a saber: el nivel de la funcionalidad básica, el nivel de la optimización del bienestar y el nivel de la complementación del bienestar. El artículo inicia con la fundamentación de la equiparabilidad de los derechos sociales de prestación con los derechos fundamentales “tradicionales o clásicos”, por ser dicha equiparabilidad el requisito teórico para justificar la justiciabilidad y efectivización de los derechos fundamentales prestacionales; a continuación, pasa a desarrollar la idea de obligación mínima esencial para luego incorporarla como primer nivel dentro de la estructura progresiva de efectivización. Finalmente, se pondrá a prueba este modelo teórico al reconstruir con base en el mismo el caso Cuscul Pivaral y otros vs. Guatemala resuelto por la Corte idh.Publicación Reseña de: Review of Weaving Tales: Anglo-Iberian Encounters on Literatures in English. Edited By Paula García-Ramírez, Beatriz Valverde, Angélica Varandas, Jason Whittaker.” NEXUS. 2025(Aedean (Asociación Española de Estudios Anglo-Norteamericanos), 2025-01-01) Gómez Galisteo, Carmen; Moreno Álvarez, AlejandraPublicación Reseña de: The Cultural Legacy of Disney: A Century of MagicBy Robyn Muir, Emily Aguiló- Pérez, Hannah Helm and Rebecca Rowe (eds.), Lanham, MD: Lexington Books, 2024. pp. 244. $110.00 (hbk)(Wiley Periodicals, 2024-12-24) Gómez Galisteo, Carmen-Publicación Sense and Sensibility Rewritten: Revising Love and Marriage in Jane Austen and Joanna Trollope’s Sequel(University of Timisoara, 2025-01-31) Gómez Galisteo, Carmen; Pârlog, HortensiaWhile most discussions of marriage in Jane Austen primarily dwell on Pride and Prejudice and its treatment, marriage is also central in Sense and Sensibility, which illustrates the penury that may befall young, single women with limited financial means. This essay analyzes Sense & Sensibility, a rewriting of Sense and Sensibility by Joanna Trollope (2013), which is set in twenty-first century England, paying close attention to how Trollope approaches love and marriage (its desirability or the obligation to get married), especially under the light of changing social mores in the twenty-first century and taking into account Austen’s own views on both issues as presented in Sense and Sensibility.Publicación Non-affine motion and selection of slip coefficient in constitutive modelling of polymeric solutions using a mixed derivative(American Institute of Physics, 2023-01) Nieto Simavilla, David; Español Garrigos, José; Ellero, MarcoConstitutive models for the dynamics of polymer solutions traditionally rely on closure relations for the extra stress or related microstructural variables (e.g., conformation tensor) linking them to flow history. In this work, we study the eigendynamics of the conformation tensor within the GENERIC framework in mesoscopic computer simulations of polymer solutions to separate the effects of nonaffine motion from other sources of non-Newtonian behavior. We observe that nonaffine motion or slip increases with both the polymer concentration and the polymer chain length. Our analysis allows to uniquely calibrate a mixed derivative of the Gordon–Schowalter type in macroscopic models based on a micro-macromapping of the dynamics of the polymeric system. The presented approach paves the way for better polymer constitutive modeling in multiscale simulations of polymer solutions, where different sources of non-Newtonian behavior are modelled independently.Publicación Making Herstory: A Reading of Miller’s Circe and Atwood’s Penelopiad(Association of Young Researchers on Anglophone Studies, 2020-12) Díaz Morillo, EsterThis article is concerned with herstories and the retelling of myths. For the purpose of the present research, we will analyse Madeline Miller’s Circe and compare it to Margaret Atwood’s The Penelopiad. North-American author Madeline Miller gives voice to goddess and sorceress Circe, protagonist of this book inhabited by other Homeric characters. For its part, The Penelopiad is a novella written by Canadian author Margaret Atwood in a series of rewritings of myths. In this book, based on the Homeric Odyssey, the focus is turned to Penelope, wife of Odysseus, who tells us her story from the Hades, as well as to her maids, hanged by Telemachus after Odysseus’s return. Both books are, therefore, related to Greek mythology and, more precisely, to Homer’s Odyssey. Both authors aim at retelling those myths through a female perspective, making use of herstory in order to do so. Analysing the novels from the perspective of feminism, we will see how the authors make their revisions of a canonical work in order to give voice to previously silenced voices in history how they present their female characters by calling myths into question, and, therefore, by challenging male authority and patriarchal society.Publicación The Pre-Raphaelites and their Keatsian Romanticism: An Analysis of the Renderings of The Eve of St Agnes and Isabella(Universidad Complutense de Madrid, 2020-11-24) Díaz Morillo, EsterThis research examines the influence of Romantic poet John Keats on the Pre-Raphaelite Brotherhood, a Victorian artistic and literary movement. The aim of this paper is to prove how Keats became, moreover, a major connecting link between Romanticism and the Victorian era, thus enabling the continued existence of certain Romantic aesthetic features until the beginning of the twentieth century. In that sense, we will explore how this influence took shape and we will analyse Pre-Raphaelite works of art which have as source of inspiration some of Keats’s well-known poems (“Isabella; or, The Pot of Basil” and “The Eve of St. Agnes”). This examination will allow us to perceive the manner in which these artists devised their pictorial style based on Keatsian pictorialism in poetry, with a special emphasis on the significance of medievalism, and the beauty and sensuousness of his verses, and how they were transferred into their canvases.Publicación La emigración irlandesa decimonónica tras la gran hambruna, parte intrínseca del carácter irlandés(UNED Universidad Nacional de Educación a Distancia (España), 2020-12-30) Díaz Morillo, EsterA lo largo de la historia han tenido lugar episodios de grandes crisis que transformarían irremediablemente la vida de millones de personas. Uno de estos acontecimientos fue la gran hambruna producida en Irlanda entre 1845 y 1851, uno de los eventos más trágicos de nuestra historia contemporánea que dejaría profundas huellas en su población. Uno de sus efectos más graves fue la oleada migratoria sin precedentes que llevó a numerosos irlandeses especialmente hasta las costas norteamericanas. Este artículo pretende, por tanto, estudiar la migración irlandesa producida por la gran hambruna y las características especiales que mostró y que la hizo distinguirse del resto de olas migratorias europeas decimonónicas. La «nueva Irlanda» que se conformaría en lugares como Estados Unidos nunca perdería su vínculo con la isla y dejaría un legado imborrable en ciudades como Nueva York y Chicago.Publicación Of the Awefull Afterlife of Cats: From the Illustrated Book to the Stage(Universidad de Valladolid, 2023-10-18) Díaz Morillo, EsterOld Possum’s Book of Practical Cats (1939) de T. S. Eliot adquirió mayor popularidad tras ser adaptado a musical por Andrew Lloyd Webber (1981). El entretenimiento popular fue para Eliot una fuente de inspiración, lo que hace especialmente interesante examinar el proceso contrario: ver cómo su poesía ha inspirado otras artes y cómo esta adaptación ha interpretado o transferido el ritmo y sentido del humor de Practical Cats. Este artículo se centra en cómo el musical Cats de Lloyd Webber está en continuidad con las teorías de Eliot sobre drama, música y baile, especialmente influenciadas por el music hall.Publicación For Evermore’: An Examination of Musical Ekphrases of E. A. Poe’s ‘The Raven(Universidad de Sevilla, 2023-10-04) Díaz Morillo, EsterThis article analyses the transfer of poetic language into music, focusing on Edgar Allan Poe’s celebrated poem “The Raven” (1845). After a theoretical study on poetic language and theoretical questions regarding transmediation, I look into different pieces of instrumental music directly inspired by Poe’s lines. To this end, I draw on ground-breaking research regarding media transformation by authors such as Lars Elleström, whose work provides the theoretical framework, and, most especially, Siglind Bruhn, who has written about the relation between poetry and music, and who coined the term “musical ekphrasis”. Finally, I argue that these composers transmediate Poe’s “The Raven” by using musical devices similar to those employed by Poe in his poem. Particularly important for this analysis will be compulsive repetition and variation as strategies of the musical ekphrasis, and the re-presentation of the uncanny in music.Publicación Consumption of the Female Body in Illustrated Editions of Christina Rossetti’s ‘Goblin Market(Universidad de Almería, 2025-05-15) Díaz Morillo, EsterChristina Rossetti’s “Goblin Market” (1862) places a great emphasis on the female body, where ravenous consumption of the forbidden fruit is associated with loss of purity. The poem has haunted the imagination of numerous artists, several of them representing the female body in a sexualised manner for voyeuristic purposes, while others refusing to commodify the female body and its experience of suffering. From a feminist perspective and through close reading, this article aims to explore how artists have portrayed the sexual connotations of Rossetti’s “Goblin Market” and their choices when depicting voracious appetite, (sexual) violence and the decaying of the female body.Publicación Impact of the Covid-19 Pandemic on Obsessive-Compulsive Disorder: A Mini-Review(Stripe Journals, 2024) Borrego Ruiz, AlejandroThe COVID-19 pandemic has been accompanied by global messaging about prevention strategies, and by measures aimed to control the transmission, significantly impacting the prevalence of obsessivecompulsive disorder and the quality of life of those affected by the condition. The present review work is aimed to analyze the most recent literature about the influence of the COVID-19 pandemic on obsessivecompulsive disorder. Multiple studies indicated a notable rise in the prevalence and severity of obsessivecompulsive symptoms. The studies also illustrated varying impacts of the pandemic on different populations. Contamination-related obsessive-compulsive symptoms worsened due to public health messaging and the associated responsibility to prevent harm, reflecting the broader psychological implications of the pandemic's context. In addition, various studies identified maladaptive coping mechanisms in response to pandemic-related stress, particularly among individuals with severe psychiatric disorders. Furthermore, the pandemic accelerated the adoption of tele-psychotherapy as a viable treatment option. Given the long-term implications of the COVID-19 pandemic on mental health, ongoing research is critical to understanding its impact on obsessive-compulsive disorder and other anxiety disorders. This review underscores the necessity for customized therapeutic strategies and public health approaches that acknowledge the complex interaction between mental health, societal stressors, and treatment accessibility in the evolving landscape of global health crises.Publicación Stability for one-dimensional discrete dynamical systems(American Institute of Mathematical Sciences, 2020-02-01) Segura, Juan; Perán Mazón, Juan JacoboWe present a new method to study the stability of one-dimensional discrete-time models, which is based on studying the graph of a certain family of functions. The method is closely related to exponent analysis, which the authors introduced to study the global stability of certain intricate convex combinations of maps. We show that the new strategy presented here complements and extends some existing conditions for the global stability. In particular, we provide a global stability condition improving the condition of negative Schwarzian derivative. Besides, we study the relation between this new method and the enveloping technique.
