MULHACEN, enhanced multi-subband Monte Carlo simulator for nonplanar FETs
No full textIn this work, we present Mulhacen, a 3D multi-subband simulator developed for the accurate study of nonplanar
devices which are at the core of present and future technology nodes. It allows to consider electrons in different
conduction band valleys and, among its main features, we can highlight the accurate evaluation of quantum
effects in the plane transverse to transport through the solution of the 2D Schrödinger equation in several
device cross sections, as well as Monte Carlo description of transport. The simulator is based on a finite
elements discretization, which allows an accurate description of realistic device geometries.Ministerio de Transformación Digital (Project. +QCHIP TSI069100-2023-0003)European Chips Joint Undertaking (HORIZON-JU-Chips-2023-RIA-CPL-2; FAMES ID 101182279)Universidad de Granada / CBUA (Open access
Análise tipológica da violência em casais jovens em Ceuta e Melilla
No full textEste estudio tiene como objetivo conocer la percepción del estudiantado
de los centros de Ceuta y Melilla de la Universidad de Granada sobre las violencias,
experimentadas y percibidas en las relaciones de parejas, así como determinar las diferencias
entre los informantes representantes del Grado en Educación Primaria (GEP) y del Grado
en Educación Infantil (GEI) de estos dos centros universitarios. El método empleado fue
cuantitativo mediante la técnica de encuesta a una muestra probabilística compuesta por
213 participantes. Como herramienta de recolección de datos se utilizó el cuestionario de
violencia en las relaciones de pareja jóvenes (VIREPA), de González-Gijón y Soriano (2021),
con el fin de conocer las diferentes violencias sufridas por los participantes. Los resultados
muestran una baja valoración de la violencia directa física y abuso sexual, y una alta valoración
del maltrato emocional, desvaloración personal y el control social y económico. Los hallazgos
indican que predomina la violencia directa (psicológica), estructural y cultural-simbólica. El
complejo panorama de las violencias en parejas jóvenes apunta a un ejemplo de violencia
hibrida, en la cual coexisten todas las violencias, reafirmando así la necesidad de promover
iniciativas para la prevención a partir del ámbito universitario.This study explores the perception of students from the Ceuta and
Melilla centers of the University of Granada on violence, experienced and perceived in
relationships, as well as to determine the differences, if any, among the students of the
Undergraduate Degree in Primary Education (PE) and in Early Childhood Education (ECE)
of these two university centers. The method used was the survey technique of a probability
sample composed of 213 subjects. As a data collection tool, the violence in young couple relationships questionnaire (VIREPA), by González-Gijón and Soriano (2021) was used to
determine the different violences experienced by the participants. The results show a low
estimation of direct physical violence and sexual abuse, and conversely a high estimation
of violence and emotional abuse, personal devaluation, and social and economic control.
The findings indicate that students of the Degree in Primary Education (Ceuta) and Early
Childhood Education (Melilla) dominate on the scale of direct (psychological), structural
and cultural-symbolic violence. The complex panorama of violence in young couples points
to an example of hybrid violence, in which all violence coexists, thus reaffirming the need to
promote prevention initiatives from the university level.Este estudo tem como objetivo conhecer a perceção dos estudantes dos centros

assim a necessidade de promover iniciativas de prevenção a partir do meio universitário
Evaluation of the landscape’s potential for alternative tourism development in the Pico Azul-La Escalera Environmental Protection Zone, Michoacan, Mexico
No full textEl estudio del turismo en las áreas naturales protegidas es una tarea de suma importancia y se ha analizado en numerosas publicaciones. Sin embargo, pocas veces se aborda desde la concepción teórico-metodológica de los paisajes como unidades de integración geográfica. El objetivo de la investigación es utilizar los polígonos de las unidades de los paisajes antroponaturales delimitadas y cartografiadas en la Zona de Protección Ambiental Pico Azul-La Escalera, Michoacán, México, para establecer su potencial en el desarrollo del turismo alternativo. Para ello, se determinó la aptitud natural para las actividades posibles a realizar como parte del turismo alternativo a partir de los indicadores: grado de naturalidad, índice de antropización de la cobertura vegetal, grado de inclinación de la pendiente, existencia de atractivos turísticos principales, complementarios y de apoyo, y la existencia de actividades económicas tradicionales o festividades. La aptitud natural, de conjunto con el análisis de la compatibilidad jurídica, la viabilidad ambiental, socioeconómica y técnico-financiera de los usos turísticos propuestos, permitió determinar el potencial de uso turístico para cada polígono de paisaje. Los resultados indican que los polígonos de paisajes con mayor potencial para el turismo alternativo se ubican al norte y noreste del ANP y son los que poseen gran parte de los bosques más conservados, la mayor cantidad de atractivos, mejor accesibilidad y, por tanto, mejores condiciones para esta actividad. Solo dos polígonos de las unidades de paisaje situadas en el centro, que presentan baja naturalidad, poseen un alto potencial turístico debido a la existencia de tradiciones culturales.The study of tourism in protected natural areas is crucial and has been extensively covered in
numerous publications. However, it is rarely examined from the perspective of landscape
units. This research seeks to determine the tourism potential of a protected area using
landscape units. The evaluation for developing alternative tourism uses anthroponatural
landscape units delineated and mapped in the Pico Azul-La Escalera Environmental Protection
Zone, Michoacán, Mexico. The natural suitability for tourism activities has been based on
indicators such as the degree of naturalness, the anthropization index of vegetation cover,
slope inclination, and the presence of main, complementary and supporting tourist
attractions, together with traditional economic activities or festivities. By combining natural
suitability with analyses of legal compatibility, environmental, socioeconomic, and technicalfinancial viability, we determine the tourism potential of these landscapes. The results show
that the landscapes with the highest potential for alternative tourism are located in the north
and northeast, featuring well-conserved areas with numerous attractions, better accessibility,
and optimal conditions for tourism. Only two landscape units in the center possess high
tourism potential due to cultural traditions, despite their low naturalness.Universidad Nacional Autónoma de México, Consejo Nacional de Humanidades Ciencia y Tecnología de México (CONAHCYT)Ayuda María Zambrano Senior - UGR - Ministerio de Universidades de Españ

Finally, the authors would also like to thank José Ferández, Professor of Statistics and Operations Research at the University of Murcia, for his help on formulating the complete optimization problem.Many real-world optimization problems related to physical environments have heavily constrained search spaces, which hinders the direct application of meta-heuristics and similar black-box methods. This work describes how to avoid region constraints and self-adapt search spaces without renouncing competitive solutions. The proposal relies on defining a gateway function that hides environment-specific placement constraints and is compatible with regular meta-heuristics and simulation-based optimization. The function can show a standard box-constrained domain encapsulating the real places involved. It has been successfully applied to automatic camera placement for task observation in a particle accelerator. The environment and the process of interest are simulated in the Unity game engine, which defines a cutting-edge trend in the design of such facilities. The primary optimization method tested is the genetic algorithm of MATLAB’s Global Optimization Toolbox, an industry standard that achieves remarkable results. The widespread Teaching–Learning-Based Optimizer (TLBO) and a random search have also been tried to complement the study. According to the results, the proposal does not prevent the advanced optimizers from finding camera arrangements that outperform (and are validated by) a human expert. It also allows the random search to find reasonable arrangements despite the underlying intricate set of constraints.DistriMuSe (HORIZON-KDT-JU-2023-2-RIA 101139769PCI2024-153511PID2021-123278OB-I00PID2022-140095NB-I00MICIU/AEI/10.13039/50110001103
The Value of MRI-Based Radiomics in Predicting the Pathological Nodal Status of Rectal Cancer: A Systematic Review and Meta-Analysis
No full textBackground: MRI-based radiomics has emerged as a promising approach to enhance the non-invasive, presurgical assessment of lymph node staging in rectal cancer (RC). However, its clinical implementation remains limited due to methodological variability in published studies. We conducted a systematic review and meta-analysis to synthesize the diagnostic performance of MRI-based radiomics models for predicting pathological nodal status (pN) in RC. Methods: A systematic literature search was conducted in PubMed, Web of Science, and Scopus for studies published until 31 December 2024. Eligible studies applied MRI-based radiomics for pN prediction in RC patients. We excluded other imaging sources and models combining radiomics and other data (e.g., clinical). All models with available outcome metrics were included in data analysis. Data extraction and quality assessment (QUADAS-2) were performed independently by two reviewers. Random-effects meta-analyses including hierarchical summary receiver operating characteristic (HSROC) and restricted maximum likelihood estimator (REML) analyses were conducted to pool sensitivity, specificity, area under the curve (AUC), and diagnostic odds ratios (DORs). Sensitivity analyses and publication bias evaluation were also performed. Results: Sixteen studies (n = 3157 patients) were included. The HSROC showed pooled sensitivity, specificity, and AUC values of 0.68 (95% CI, 0.63–0.72), 0.73 (95% CI, 0.68–0.78), and 0.70 (95% CI, 0.65–0.75), respectively. The mean pooled AUC and DOR obtained by REML were 0.78 (95% CI, 0.75–0.80) and 6.03 (95% CI, 4.65–7.82). Funnel plot asymmetry and Egger’s test (p = 0.025) indicated potential publication bias. Conclusions: Overall, MRI-based radiomics models demonstrated moderate accuracy in predicting pN status in RC, with some studies reporting outstanding results. However, heterogeneity in relevant methodological approaches such as the source of MRI sequences or machine learning methods applied along with possible publication bias call for further standardization and preclude their translation to clinical practice.Instituto de Investigación Biosanitaria (ibs.GRANADA) (grant “INTRAIBS-PI-2025-13”
The water route from its springs to the medina of the Alhambra and Granada in the islamic period
No full textEl presente artículo aborda los sistemas hidráulicos que
hicieron posible el abastecimiento de agua a Granada y
la Alhambra antes, durante y después de la dominación
islámica de este territorio. Con origen en la Iliberri-Florentia
romana, fue en los siglos siguientes cuando se originó el
complejo sistema de acequias, canalizaciones e ingenios
hidráulicos que, desde la dinastía zirí (siglo XI) y pasando por
almorávides y almohades (XI-XIII), llegó a su esplendor en la
dinastía nazarí (XIII-XV). Las acequias de Aynadamar, Real
de la Alhambra, del Cadí y otras; el acueducto del rey Chico o
el albercón de las Damas entre otros, fueron construcciones
fundamentales para el desarrollo del arte y cultura nazarí,
así como para el levantamiento de la Alhambra. Tras la
conquista cristiana estos sistemas de abastecimiento fueron
descuidados hasta principios del siglo XX, cuando Torres
Balbás inició su moderna consideración patrimonial y

possible the supply of water to Granada and the Alhambra
before, during and after the Islamic domination of this
territory. With its origins in the Roman Iliberri-Florentia,
it was in the following centuries that the complex system
of irrigation ditches, canals and hydraulic devices was
created, which, from the Zirid dynasty (11th century) and
passing through the Almoravids and Almohads (11th-13th
century), reached its splendor in the Nasrid dynasty (13th15th century). The irrigation ditches of Aynadamar, Real de
la Alhambra, del Cadí and others; the rey Chico aqueduct or
the albercón de las Damas among others, were fundamental
constructions for the development of Nasrid art and culture,
as well as for the construction of the Alhambra. After the
Christian conquest, these supply systems were neglected
until the beginning of the 20th century, when Torres
Balbás began their modern heritage consideration and

locales, procesos transnacionales» (PID2021-128307OB-I00), proyectos financiados por el Ministerio de Ciencia, Innovación y Universidades.La reapropiación de la canción infantil fue una de las estrategias de resistencia de las cantautoras frente a los roles de género impuestos por el franquismo. Rosa León reivindicó el género como canción protesta en los 70, tras interpretar en RTVE temas de María Elena Walsh. La poeta argentina diluía la dicotomía entre lo infantil y lo adulto, un empeño compartido por Julia León y Elisa Serna, quien convirtió una “canción de cuna” en un homenaje a la activista Lola González Ruiz. Otras cantautoras, como María Manuela, movilizaron en discos infantiles a poetas como Rosalía de Castro para reivindicar, en gallego, una nueva idea de mujer. Con estas acciones, las cantautoras no solo resignificaron un rol asignado por la dictadura y reforzado por el mercado discográfico, sino que trazaron genealogías feministas y llevaron la canción “protesta” a la televisión y la prensa rosa, a la infancia y a sus cuidados.Female singer-songwriters resisted the gender roles imposed by Francoism by reclaiming children’s music, a genre appropriated to reinforce its ideology. In the 1970s, Rosa León framed the genre as a vehicle for protest, performing María Elena Walsh’s songs on RTVE. The Argentine poet blurred the boundaries between childhood and adulthood, a strategy also embraced by Julia León and Elisa Serna, who repurposed the label “children’s song” for their artistic and political objectives. Serna, for instance, turned a lullaby into a homage to activist Lola González Ruiz. Other singer-songwriters, such as María Manuela used children’s albums to draw on poets like Rosalía de Castro, advocating, in Galician, a new vision of womanhood. Through these actions, these artists not only subverted a role imposed by the regime and reinforced by the music industry but also traced feminist genealogies and extended protest music to television and celebrity journalism, to children, and their care.Agencia Estatal de Investigación de EspañaHorizon 2020 (UE, GA n.º 101034324)Ministerio de Ciencia, Innovación y Universidades PID2021-125022NB-I00, PID2021-128307OB-I0
The color of natural teeth: A scoping review of In-Vivo studies
No full textObjectives:
This review aimed to analyze and present information on the color of natural teeth and its distribution based on color measurement methods, types of studies, and research areas. Additionally, it identified knowledge gaps in dental color science and suggested areas for future research.
Data:
This review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) Checklist.
Sources:
An electronic search was conducted in Medline/Pubmed, Scopus, and Web of Science - all databases using the keywords: human, tooth, color, color difference, spectrophotometer, colorimeter, spectroradiometer. The review included exclusively English-written research articles published after 1979, focusing on those in-vivo protocols that instrumentally evaluated the color of natural human teeth and provided CIEL*a*b*, CIEL*C*h° color coordinates, and/or shade guide designation.
Study selection:
The initial database search yielded 2501 results: Medline/Pubmed: n = 482; Scopus: n = 334; and Web of Science All databases: n = 1685. After selection, 53 research articles were included in the review.
Conclusion:
Dental color is a complex phenomenon to objectively record, communicate, and reproduce. Although studies have reported color coordinates based on age, gender, ethnicity, and tooth type, there is no consensus within the scientific community. Most studies are cross-sectional, limiting the understanding of tooth color changes over time. Longitudinal studies involving diverse cultures with adequate sample sizes and consistent methodologies are necessary for objective color recording.
Clinical significance:
Studies assessing the color of in-vivo natural teeth show a high level of heterogeneity due to the diversity in the type of measurement devices used, experimental conditions, illuminant, number of teeth used, area of measurement, and color coordinates reported. Future research must consider more extensive and representative population samples, with standardized reporting of demographic characteristics (age, gender, ethnicity), and more detailed inclusion and exclusion criteria. It is crucial to prioritize the standardization of measurement conditions, using a non-contact instrument, calibration, and detailed reporting of color.Iuliu Hatieganu University of Medicine and Pharmacy Cluj-Napoca - Institutional open access progra
