Tibial slope in ACL reconstruction: When should it be corrected?
(Elsevier, 2026) Pineda, Tomás; Dejour, D. H.
The tibial slope has been identified as a key anatomical factor influencing anteroposterior knee stability. Increased slope values have been linked to greater anterior tibial translation, higher stress on the anterior cruciate ligament and an elevated risk of graft failure following reconstruction. This review aims to examine the current evidence and ongoing controversies regarding the clinical relevance of tibial slope, measurement methods, and surgical correction indications.
Viola acherontia: Diseño, arte y manipulación genética
(Universidad politécnica de Madrid, 2026-05-04) Menteguiaga, Clarisa
Este artículo explora cómo la creación contemporánea puede intervenir en los sistemas vivos de manera ética y ecológicamente responsable, en contraste con la forma artificial en que opera la manipulación genética en diversas esferas de nuestra existencia. La investigación adopta una
interdisciplinaria, integrando perspectivas de la biotecnología, el biodiseño, el arte contemporáneo y la literatura especulativa. Se examinan estrategias de diseño que incluyen el uso de procesos biológicos, simulaciones y materiales bioinspirados para generar experiencias sensoriales, narrativas y conceptuales que revelan procesos invisibles y relaciones de interdependencia entre humanos, otros seres y ecosistemas. Se observa que el diseño puede funcionar como un hacer proyectual y conceptual que articula ciencia, ética y estética, y que promueve la reflexión crítica sobre la intervención en la vida. Asimismo, se destaca que el diseño no se limita a la creación de objetos, sino que constituye un marco para especular sobre futuros posibles, construir narrativas éticas y desarrollar prácticas colaborativas con sistemas biológicos. Se concluye que el diseño, entendido como herramienta de mediación, cuidado y experimentación, puede abrir espacios para la innovación responsable, fomentando la conciencia ecológica, la sensibilidad hacia los seres vivos y el diálogo crítico sobre la relación entre humanos, naturaleza y tecnología.
Beyond bloch: A teotherical blueprint of conjugated polymer optoelectronics
(IOP Publishing, 2026-03-31) Lagos, Miguel; Kiwi, Miguel; Paredes, Rodrigo
Conjugated polymers have recently regained strong interest because of their potential in organic electronic devices such as organic light-emitting diodes (OLEDs), field-effect transistors (FETs), and organic photovoltaics (OPVs). Unlike inorganic semiconductors where electrons are commonly treated as delocalized or quasi-free Bloch states,electrons in conjugated polymers occupy strongly coupled, localized σ and π orbitals and interact intensely with the ionic lattice. These materials therefore deviate markedly from the assumptions underlying Bloch-based approaches, motivating the development of alternative theoretical descriptions of charge transport. Here we present a many-body model that explicitly includes electron-electron interactions, both on-site and between π states on alternating chain sites. The model naturally explains semiconducting behavior in the undoped polymer and predicts two novel flat bands of excited bonding states. These excited states exhibit bosonic character and enable an unconventional charge-transport channel. The model also quantitatively reproduces experimental observations, yielding excellent fits to measured UV-Vis absorption and electro-luminescence spectra.
Touching the invisible: learning electromagnetism in virtual worlds
(Emeral Publishing, 2026-04-10) Bopp Ibar, María-Jesús; Mora Serrano, Francisco Javier; Proboste M., Mahias; del Arco, Albert; Cervera, Miguel; Muñoz La Rivera, Felipe
Purpose – Engineering education, particularly in complex fields like electromagnetism, faces a significant challenge in conveying multiphysics systems. Traditional methods fall short in building deep, intuitive understanding. The purpose of this paper is to address this “cognitive interface challenge” by presenting a novel conceptual framework for creating human-centric, interactive learning environments to bridge this gap. Design/methodology/approach – This paper details a methodology of interdisciplinary knowledge transfer. The proposed conceptual framework is derived from a multi-year analysis of best practices in the Architecture, Engineering, Construction and Operations sector, which has already developed mature solutions for navigating complex three-dimensional digital twins. Findings – The primary contribution is a formal four-stage methodological framework for developing human-centric virtual environments. This model moves beyond traditional tools to create interactive systems based on defined cognitive goals and proven interactive design paradigms, providing a new, robust method for the computation and mathematics community. Research limitations/implications – As a conceptual paper, the primary implication is the need for empirical validation of the proposed four-stage framework. Future research should focus on implementing and testing the framework’s effectiveness against traditional methods in controlled educational and professional settings.
Intelligent Grid Support with VPPs: A Scalable Solution for PMGD Integration Challenges
(IEEE Xplore, 2026-04-20) Córdova, Felisa; Yanine, Fernando; de Saint Pierre, Thierry; Rother, Hans; Aly, Mokhtar
Power quality issues and blackouts in electric distribution systems, such as the recent outage affecting Spain and parts of Portugal, are increasingly linked to grid imbalances caused by the growing penetration of Distributed Generation (DG), particularly medium-sized photovoltaic plants (PMGD). These systems inject all their power into the grid, often causing disturbances in the grid's power supply. They also require constant coordination with nonrenewable backup plants, leading to instability in frequency and voltage. To address these challenges, Virtual Power Plants (VPPs) offer a scalable and rapidly deployable solution, integrating large-scale energy storage, advanced diagnostics, and real-time control to provide ancillary services, stabilize supply, and reduce the burden on traditional infrastructure. There is also a need to rapidly diagnose the grid's disturbances and readily intervene to remediate the condition. In this paper, the need for VPP in renewable energy-rich power grids is discussed. A solution termed SiVUr is introduced, which helps diagnose and then intervene the grid with VPP, employing Artificial Intelligence (AI) to optimize the VPP's effectiveness in mitigating disturbances. This solution creates dynamic interactions between DERs and loads, which is crucial for modern power grids. As PMGD integration accelerates, it becomes essential to maintain the grid's reliability, flexibility, and service quality in increasingly complex and decentralized energy environments.
