Identification of emotions and physiological response in individuals with moderate intellectual disability
(Taylor & Francis, 0001) Agustín Ernesto Martínez-González; Veas Iniesta, Alejandro; Psicología Evolutiva y de la Educación; Facultades de la UMU::Facultad de Psicología y Logopedia
According to Ekman’s model, the basic emotions are anger, disgust, fear, happiness, sadness, and surprise. These emotions are universal and have an adaptative function. However, studies on these emotions among individuals with moderate intellectual disability (MID) are limited, mainly owing to issues in sample size and sample homogeneity. The present study aimed to explore differences between a MID group (n = 10) and a non-MID control group (n = 10) in 1) the identification of basic emotions; and 2) the physiological response with images related to fear, happiness, sadness, anger, and disgust, as well as images with neutral and sexual content. A total of 29 images from The International Affective Picture System and a biofeedback measurement system were used. The results showed no statistically significant differences in the identification of the basic emotions of fear, sadness, and disgust. However, statistically significant differences were found for happiness (p = .008), anger (p = .02), and neutral images (p = .02), and minor statistically significant differences were found for images with sexual content (p < .01) in MID individuals with respect to the control group. The MID group’s physiological response was lower compared with the control group, with statistically significant differences for all emotional visual stimuli. This preliminary study showed important and interesting results for the study of emotions and sexuality in MID. Future studies should consider the sample size, sex and age comparisons, and the different levels of intellectual disability.

Ferrioxalate Photocatalysis: A Multitasking Platform for Reductive Iron Catalysis
(AAAS, 0001-01-01) Carlos Bernabeu; Sergio Adalid; Sara Colombo; Nojus Cironis; Partha Pratim Sen; Ken Okuno; Fabio Juliá; Juliá Hernández, Fabio; Fabio Juliá; Química Inorgánica; Fabio Juliá; Facultades de la UMU::Facultad de Química
Iron’s abundance motivates its use in sustainable catalyst systems that also offer complementary reactivity manifolds compared to precious metals. However, the challenging reduction of benchmark iron salts to active species hinders their application in reductive transformations. Here we report a photochemical strategy that exploits the innate reactivity of ligand-to-metal charge-transfer (LMCT) excited states of iron oxalate complexes to harness oxalate salts as latent terminal 2-electron reductants in iron catalysis. The investigation of this activation mode has led to the development of a versatile catalytic platform enabling transformations hitherto inaccessible to previous iron catalyst systems. The synthetic value of this tactic is demonstrated on diverse reductive transformations using readily available building blocks with high chemoselectivity, opening new synthetic opportunities.

(0001-09-16) M. Victoria Moreno; Fernando Terroso-Sáenz; González Vidal, Aurora; Valdés Vela, Mercedes; Skarmeta Gómez, Antonio; Zamora Izquierdo, Miguel Ángel; Victor Chang; Ingeniería de la Información y las Comunicaciones; Facultades de la UMU::Facultad de Informática
This paper presents the main foundations of big data applied to smart cities. A general Internet of Things based architecture is proposed to be applied to different smart cities applications. We describe two scenarios of big data analysis. One of them illustrates some services implemented in the smart campus of the University of Murcia. The second one is focused on a tram service scenario, where thousands of transit-card transactions should be processed. Results obtained from both scenarios show the potential of the applicability of this kind of techniques to provide profitable services of smart cities, such as the management of the energy consumption and comfort in smart buildings, and the detection of travel profiles in smart transport.

Catalysis in the excited state: bringing innate transition metal photochemistry into play
(American Chemical Society, 0005-03-05) Juliá Hernández, Fabio; Química Inorgánica; Facultad de Química
Transition metal catalysis is an indispensable tool for organic synthesis that has been harnessed, modulated and perfected for many decades by careful selection of metal centers and ligands, giving rise to synthetic methods with unparalleled efficiency and chemoselectivity. Recent developments have demonstrated how light irradiation can also be recruited as a powerful tool to dramatically alter the outcome of catalytic reactions, providing access to innovative pathways with remarkable synthetic potential. In this context, the adoption of photochemical conditions as a mainstream strategy to drive organic reactions has unveiled exciting opportunities to exploit the rich excited-state framework of transition metals for catalytic applications. This Perspective examines the advances on the application of transition metal complexes as standalone photocatalysts, exploiting the innate reactivity of their excited states beyond the common use as photoredox catalysts. An account of relevant examples is dissected to provide a discussion on the electronic reorganization, the orbitals involved and the associated reactivity of different types of excited states. This analysis aims to provide practitioners with fundamental principles and guiding strategies to understand, design and apply light-activation strategies to homogeneous transition metal catalysis for organic synthesis.

Evidence-based practice competence among nurses in acute and critical care settings: a national cross-sectional study in Spain – The #Evidencer Project
(Elsevier, 0012-05-26) Segura López, Gabriel; Cayuela Fuentes, Pedro Simón; Leal Costa, César; Vera Pérez, José Antonio; Ruzafa Martínez, María; Ramos Morcillo, Antonio Jesús; Enfermería; Facultades de la UMU
Objectives: This study assessed EBP competence among critical care nurses in Spain and identified significant factors affecting the integration of EBP into clinical practice. Methods: A multicenter cross-sectional study involved nurses in emergency departments, pre-hospital emergency services, and intensive care units throughout Spain. Competence was assessed through self-report using the validated EBP-COQ Prof© questionnaire, comprising 35 items divided into four dimensions: attitude, knowledge, skills, and utilization. Descriptive, bivariate, and multivariate regression analyses were conducted to identify the predictors of EBP competence. Results: The sample comprised 847 nurses (78.5% female; mean age 39.89 years, SD = 9.13). The average total EBP competence score was 130.6 (SD = 17.29). Scores across dimensions were highest for attitude (37.1/40) and knowledge (38.0/55), while skills (23.0/30) and utilization (32.6/50) were lower. Key predictors of higher competence included EBP training (p < 0.001), regular reading of scientific articles (p < 0.001), postgraduate education (p < 0.001), mentorship roles (p = 0.018), and employment at Best Practice Spotlight Organization® (BPSO) centers (p = 0.001). Competence declined slightly with increasing professional experience (p = 0.037). Conclusions: Spanish critical care nurses exhibit moderate to high competence in evidence-based practice (EBP), showcasing solid attitudes and knowledge but lacking practical application. Healthcare institutions should emphasize organized EBP training to close this gap, encourage research involvement, and cultivate supportive environments by implementing initiatives such as BPSO programs. Tackling these elements can bolster EBP implementation and enhance patient outcomes in critical care environments. Implications for clinical practice: These findings emphasize the need for strategies to improve evidence-based practice (EBP) in critical care. Healthcare organizations should focus on structured EBP education, regular access to scientific literature, and mentorship, including BPSO® programs. Enhancing EBP skills among experienced nurses can boost decision-making, patient safety, and care quality in high-acuity settings environments.

A Data-Centric Algorithmic Pipeline for Enhancing Cardiac MRI Segmentation Using ViTUNeT and Quality-Aware Filtering
(MDPI, 0015-03-06) Salvador de Haro; Jesús Cámara; González Férez, María Pilar; José Manuel García; García Carrasco, José Manuel; Bernabé García, Gregorio; Ingeniería y Tecnología de Computadores; Facultades de la UMU::Facultad de Informática
The performance of deep-learning-based segmentation models is strongly dependent on the quality of the input data, which is frequently heterogeneous or degraded in real-world medical imaging scenarios. This work presents a data-centric algorithmic pipeline designed to improve cardiac MRI segmentation accuracy through systematic image enhancement and automatic slice-quality filtering. The proposed method is formalized as deterministic algorithm that combines image processing and supervised learning components. The approach integrates a contrast- and structure-preserving enhancement stage, based on bilateral filtering and adaptive histogram equalization, with a quality-aware selection algorithm. Slice quality is assessed using anatomical attributes extracted via YOLOv11sbased localization and a supervised classification model trained to identify diagnostically reliable images. When applied to transformer-based segmentation architectures such as ViTUNeT, the pipeline yields consistent improvements across all evaluation metrics without increasing model complexity or training cost. These findings emphasize the importance of algorithmic data curation as an effective strategy for enhancing robustness and stability in deep-learning segmentation pipelines and demonstrate the broader applicability of the proposed approach to computer-vision tasks involving heterogeneous or low-quality image datasets.

Characterization of machine learning compilers for LLM inference on NVIDIA GPUs
(Springer, 0015-05-15) Alejandro Carmona-Martínez,; Bernabé García, Gregorio; José Manuel García; Ingeniería y Tecnología de Computadores; Facultades de la UMU::Facultad de Informática
AI inference is conflicted between Performance, developer Productivity, and device Portability–the P3 problem. Machine learning compilers (MLCs) aim to address this, but their ecosystem is fragmented, with tools that each prioritize a different issue. This paper evaluates the deployment trade-offs of PyTorch-based LLMs on NVIDIA GPUs using four intertwined prominent MLC tools: torch.compile, TensorRT, XLA, and ONNX Runtime. A dual methodology is used, leveraging synthetic PyTorch models to isolate optimizations and end-to-end benchmarks with State-of-the-Art (SOTA) models (TinyLlama-1.1B, Llama-2-7B) to measure realworld performance. Findings reveal that the peak performance of Ahead-Of-Time (AOT) compilation requires architecture-specific tools such as TensorRT-LLM, which are necessary for SOTA LLMs but are unusable for PyTorch models. As for Just-In-Time (JIT) solutions such as torch.compile and its backends, they are flexible and portable, compatible with all tested models, but they do not consistently accelerate LLMs; therefore, the choice of MLC depends on P3 considerations and model architecture.

The Question at the Heart of Assessment in Higher Education: Are We Assessing for Competency Acquisition?
(MPDI, 0016-04-26) Claudia González López; Abraham Bernárdez-Gómez; Bolarín Martínez, María José; Didáctica y Organización Escolar; Facultades de la UMU::Facultad de Educación
European universities are increasingly adopting competency-based education to enhance transfer between academic and professional contexts, demanding assessment systems aligned with classroom practices. This study explores what is assessed in three Spanish universities. Spain constitutes a particularly relevant case: its course guides are legally binding contracts subject to external audit by the National Agency for Quality Assessment and Accreditation (ANECA), ensuring exceptional standardization. A theory-driven documentary analysis examined 7810 teaching guides from all degree programs, with coding supported by ATLAS.ti software applied to these documents, which represent statements of intent by faculty members. The findings reveal notable discrepancies: competencies were rarely the central focus of assessment, and evaluation appeared fragmented, overlooking the integration of knowledge, skills, and attitudes. These gaps raise concerns about the innovative dimension of competency-based models. The study concludes that institutional assessment schemes should promote holistic education, ensuring students develop collaborative and cross-disciplinary capacities essential for professional environments.

Optimizing an Organocatalyzed Process in an Undergraduate Laboratory: A Solvent Screening
(American Chemical Society, 0019-11-19) Puigcerver Alarcón, Julio; Martínez Cuezva, Alberto; Química Orgánica
In this undergraduate organic laboratory study, an extensive solvent screening has been 10 meticulously designed for the optimization of the L-proline-organocatalyzed intermolecular aldol reaction involving acetone and p-nitrobenzaldehyde. The experimental procedure entailed selecting specific solvents, analyzing the reaction crude through NMR spectroscopy, and subsequently, purifying the aldol adducts to measure their enantiomeric ratios via HPLC provided with chiral column. Remarkably, this comprehensive investigation was efficiently conducted within two concise 2-hour 15 laboratory sessions, together with 1-hour seminar session, rendering it highly suitable for both Bachelor's and Master's degree programs. Conducted at room temperature, the experiments unveiled significant variations in both yields and enantiomeric excess of the aldol products, and the byproducts proportions, depending on the solvent of choice. This experiential learning opportunity empowers students to gain practical insights into organocatalyzed transformations, purification techniques, and 20 chromatographic analysis, enhancing their proficiency as organic chemists.

The role of relationship promoter in new product development collaboration
(Taylor and Francis Group. Routledge, 0020-06-20) Sánchez-Marín, Gregorio; Pemartín González-Adalid, María; Munuera Alemán, José Luis; Organización de Empresas y Finanzas
Since new product development (NPD) collaborations with external partners have become the next generation in NPD practices, relationship promoters have become especially relevant as key contributors to the success of this type of inter-organisational collaboration. To realise successful outcomes in NPD collaborations, partners face the challenge of effectively integrating the role of relationship promoter into their existing and essential relationships of trust. It is within this context that this paper examines the role of the relationship promoter, by analysing its moderating effect on the relationship between trust and the outcomes of NPD collaboration – including new product competitiveness and partner satisfaction. We test our hypotheses against survey data from 107 innovative firms involved in NPD collaboration with the help of relationship promoters. The results show that, while a non-significant influence can be reported about the presence of a relationship promoter in terms of partner satisfaction, the relationship promotor weakens the influence of trust on new product competitiveness, making trust less important when it comes to creating a competitive new product.

Group exercise in long-term care facilities, alignment with World Health Organization recommendations: a cross-sectional survey
(Springer Nature, 0022-02-25) Montilla Herrador, Joaquina; Poveda López, Salud; Lillo Navarro, Carmen; Fisioterapia; Facultades de la UMU::Facultad de Medicina
Background: Maintaining functional status in institutionalized older people is a challenge for long-term care (LTC) institutions. In this regard, exercise may have positive effects. The World Health Organization (WHO) has issued guidelines which include recommendations of exercise for each population group. Nonetheless, the literature shows that the levels of exercise among institutionalized population are still low. Aims: This study sought to determine: (1) the characteristics of exercise programs for older people performed by health professionals in LTC facilities, (2) the knowledge and use of the WHO recommendations and guidelines for exercising among older people in LTC facilities; (3) the limitations identified by health professionals regarding the application of the WHO guidelines. Materials and methods: A cross-sectional national survey following STROBE guideline was performed. Sample: professionals developing exercise programs for institutionalized older people. A Delphi study was conducted to create the survey which included sociodemographic data, exercise characteristics, knowledge about WHO recommendations and limitations regarding their application. Descriptive statistics were used on the data, such as Pearson's χ2 and independent t- test. Results: Many professionals do not know (27,5%) or do not follow (52%) the guidelines proposed by the WHO. There is a low weekly frequency for strength exercises (30%) and aerobic exercise (51%). The professional contract influences the weekly frequency of exercise. Most identified limitations for using the WHO recommendations were the lack of time and large groups. Discussion and conclusions: Recommendations of WHO guidelines are familiar to many professionals, however, some are difficult to implement in exercise programs in LTC facilities.

La independencia judicial en serio: una propuesta de regulación
(Facultad de Derecho de la Universidad de Valencia, 0022-12-19) Mateos Martínez, J.; Fundamentos del Orden Jurídico y Constitucional; Facultades de la UMU::Facultad de Derecho
There is currently a general consensus on the existence of a scope of discretion, the extent of which is debated but in our opinion is high, available to the judge to apply the law. This leads to the need to analyze the extra-legal factors, from the ideology and social background of the judge to his or her political loyalties or personal ambitions, which may have an impact on his or her independence and lead to unreasonable sentences that are highly detrimental to the judiciary or the public in general. In short, it is essential to promote judicial independence through specific legislative measures, and to this end we will devote this paper to examining in detail the threats to such independence and proposing regulatory solutions to address them.

Chitosan as stabilizing agent for negatively charged nanoparticles
(Elsevier, 0024-12-16) Mercedes G Montalbán; Jorge Peña-García; Horacio Pérez-Sánchez; Gloria Víllora; F Guillermo Díaz Baños; Collado-González, Mar; Ingeniería Química; Facultades de la UMU
Chitosan is a biocompatible polysaccharide with positive Z potential which can stabilize negative charged nanoparticles. Silk fibroin nanoparticles and citrate gold nanoparticles, both with negative Z potential, but they form aggregates at physiological ionic strength. In this work, we study the behavior of chitosan in solution when the ionic strength of the medium is increased and how the concentration of chitosan and the proportion of the two components (chitosan and AuNP or SFN) significantly affect the stability and size of the nanocomposites formed. In addition to experimental measurements, molecular modeling were used to gain insight into how chitosan interacts with silk fibroin monomers, and to identify the main energetic interactions involved in the process. The optimum values for obtaining the smallest and most homogeneous stable nanocomposites were obtained and two different ways of organization through which chitosan may exert its stabilizing effect were suggested.

(0026-07-14) María del Mar Collado-González; María Piedad Fernández-Pérez; Manel B Hammouda; Lana Tolordava; Mariam Gamkrelidze; Collado-González, Mar; Montenegro Arce, María Fernanda; Rodríguez López, José Neptuno; Bioquímica y Biología Molecular A; Facultades de la UMU
Background: Because oestrogen receptor α (ERα) regulates E2F1 expression to mediate tamoxifen resistance in ERα-positive breast cancer cells, we aimed to define the possible roles of ERα and E2F1 in promoting the resistance of ERα-negative breast cancer cells to 4-hydroxy-tamoxifen (4OHT). Methods: This study utilised conventional techniques to demonstrate the effects of 4OHT on the expression of ERα and E2F1 and also examined the individual and combined effects of 4OHT with dipyridamole (DIPY) and 3-O-(3,4,5-trimethoxybenzoyl)-(-)-catechin (TMCG) on the oestrogen-negative MDA-MB-231 breast cancer cell line using viability assays, Hoechst staining, MALDI-TOF mass spectroscopy, and confocal microscopy. Results: Despite the ERα-negative status of the MDA-MB-231 cells, we observed that 4OHT efficiently up-regulated ERα in these cells and that this upregulation promoted E2F1-mediated cell growth. Because E2F1 plays a dual role in cell growth/apoptosis, we designed a therapy incorporating TMCG/DIPY to take advantage of the elevated E2F1 expression in these 4OHT-treated cells. 4OHT enhances the toxicity of TMCG/DIPY in these ERα-negative breast cancer cells. Conclusions: Because TMCG/DIPY treatment modulates the methylation status/stability of E2F1, the results demonstrate that therapies targeting the epigenetic machinery of cancer cells in the presence of verexpressed E2F1 may result in efficient E2F1-mediated cell death.

Effect of different enamel preconditioning protocols on the adhesion of ceramic brackets
(0028-05-26) Lara Cendán; Luis-Alberto Bravo-González; Bravo González, Luis Alberto; Ortiz Ruiz, Antonio José; Martínez Beneyto, Yolanda; Vicente Hernández, Ascensión; Dermatología, Estomatología, Radiología y Medicina Física; Facultades de la UMU::Facultad de Medicina
This study aimed to compare the adhesion of Clarity Advanced ceramic brackets bonded with APC Flash Free (APC FF) and Transbond XT (TXT) using different enamel conditioning protocols. Brackets were bonded to extracted bovine incisors, which were divided into 6 groups: 1)Transbond Plus Self Etching Primer (TSEP)/APC FF, 2)Etching/TSEP/APC FF, 3)Polishing/TSEP/APC FF, 4) TSEP/TXT, 5)Etching/TSEP/TXT and 6)Polishing/TSEP/TXT. Shear bond strength was measured using a universal testing machine. After debonding, each tooth was assigned an Adhesive Remnant Index (ARI) score. The enamel was observed using a scanning electron microscope (SEM). The penetrability of TSEP and composites was determined using confocal microscopy. The bond strength of Etching/TSEP/TXT and Polishing/TSEP/TXT groups was significantly higher than that of the remaining groups, with Etching/TSEP/TXT being significantly higher than Polishing/TSEP/TXT (p<0.05). With APC FF, there was a tendency for an increase in residual adhesive when etching and with TXT when polishing. SEM showed that etching produced the most porous enamel surface. For both APC FF and TXT bonded brackets, TSEP penetration was similar and significantly higher after etching (p=0.000). APC FF and TXT had similar and significantly higher penetration in the etched groups (p=0.000). Ceramic brackets bonded with TXT pre-etching the enamel before applying TSEP showed the most favourable adhesive characteristics.
