Search for magnetic monopoles with the complete ANTARES dataset
No full textThis study presents a search for magnetic monopoles using the full ANTARES dataset collected over 14 years
(2008--2022). The interaction of monopoles with matter was modeled according to the Kazama, Yang and
Goldhaber cross-section, and dedicated reconstruction strategies were applied to probe velocities both above
and below the Cherenkov threshold. No signal consistent with monopoles was found. We derive 90% C.L. upper
limits on the flux of relativistic monopoles at the level of 10−18 cm−2 s−1 sr−1, improving upon previous ANTARES
results and confirming those obtained by IceCube and other neutrino telescopes. These results constitute the final
contribution of ANTARES to the search for magnetic monopoles.Labex UnivEarthS (ANR-10-LABX-0023, ANR-18-IDEX-0001)MCIN/AEI/10.13039/501100011033 (PID2021-124591NB-C41, C42, C43; PDC2023-145913-I00)EU NextGenerationEU (PRTR-C17.I01
Dispersed alkaline substrate passive treatment technology for highly contaminated acid mine drainage: 20 years of successful application
No full textOver the past two decades, Dispersed Alkaline Substrate technology (DAS) has emerged as a highly effective passive approach to treating acid mine drainage with extreme acidity and metal loading. By mixing alkaline materials - such as limestone, magnesia, barium carbonate or industrial by-products - into an inert wood-chip matrix, DAS systems maintain high porosity and neutralization capacity without rapidly clogging. This treatment technology has evolved from laboratory trials to pilot and full-scale field testing, using multi-step systems integrated with Natural Fe-Oxidizing Lagoons (NFOL) for pre-oxidation, which have demonstrated their long-term effectiveness for acidity and metal removal. The sustainability and applicability of the process has been improved by the search for new reagents (e.g. MgO for divalent metals removal, BaCO₃ for sulfate removal, wood ash or calcite-rich waste for cost reduction). Field trials in diverse regions - from the Iberian pyrite belt to South Africa, Canada, South America, Asia, Europe and Oceania - report net acid removal often exceeding 95 % and near complete retention of metal(loid)s such as Al, Cu, Zn, Pb and As. Mineralogical analyses indicate that contaminants precipitate primarily as hydroxides, oxyhydroxides, and sulfates (e.g., schwertmannite, basaluminite, barite), allowing targeted valorization of metal-rich sludges. Remaining challenges include assessing long-term reagent life under variable hydrological conditions, extending full-scale use to phosphogypsum and other industrial leachates, and developing strategies for residue stabilization and resource recovery. The aim of this review is to synthesise these developments, assess current performance and identify future research needs for the advancement of passive DAS treatment technology.MICIU/AEI - European Union, NextGeneration EU/PRTR (ERA-MIN3 SuMRee project, PCI2024-153500)MCIU/AEI - FSE+ (Juan de la Cierva Postdoctoral Fellowship, JDC2023-052111-I)Universidad de Huelva / CBUA (Open acces
New TiO₂-Ag/BEA composites with dual Ag-functionalization for specific adsorption and catalytic sites. Synergism between phases in the ethylene removal for climateric fruit conservation
No full textA new series of TiO2-Ag/BEA composites was specifically designed for use in filter/photo-reactors intercalated in
air recirculation circuits in storage facilities for climacteric fruits. The sol-gel procedure for TiO2 deposition was
combined with ionic exchange (IE) or incipient wet impregnation (IWI) techniques for Ag doping, with the
proportions of both fractions also varying. The prepared materials were thoroughly characterized in terms of
their porous texture, chemical composition, crystalline structure, and Ag dispersion, among other properties.
Dynamic ethylene adsorption was recorded in the dark. After saturation, ethylene photooxidation was analyzed
under UV or UVA-visible light, with varying contact times, flow rates, and concentrations, and with or without
humidity present. The maximum ethylene adsorption capacity (361 μmol g− 1
) corresponds to the sample with
the highest Ag content (5 wt%), added by IE, while the best photocatalytic performance is obtained for samples
doped by IWI. The performance of the samples was found to be correlated with their physicochemical properties
and was specifically determined by the nature and dispersion of the silver species in the composites. Total
ethylene photooxidation is achieved even under UV–Vis radiation; the reaction develops selectively to CO2 in all
cases, despite the strong negative effect of humidity on the formation of more active HO• radicals. The high
adsorption capacity and effective photooxidation of ethylene enable control of this maturation hormone below
the established limits.FCT (Fundação para a Ciência e a Tecnologia) – (Nano4fresh-PRIMA/0015/2019, UIDP/00100/2020 (CQE), UID/00097/2030 (CEGIST), LA/P/0056/2020 (IMS), PhD grant 2022.12593.BD)MCIN/AEI/10.13039/501100011033 – European Union Next Generation EU/PRTR (PCI2020-112045, PID2021-126579OB-C31, Ramon y Cajal research contract RYC-2019-026634-I)MCIN/AEI/10.13039/501100011033 – ERDF “A way of making Europe” (PID2021-126579OB-C31)Consejería de Universidad, Investigación e Innovación – Junta de Andalucía (P21_00208)Universidad de Granada / CBUA (Open access

An accelerometer-based single-arm dynamic stability test for the assessment of the sensorimotor control of the shoulder
No full textThe study aimed at designing and validating a variation of the Single-Arm Dynamic Stability test as performed in Open Kinetic Chain for assessing the shoulder’s sensorimotor control with the subject lying supine while holding a dumbbell still in one hand with the extended arm. The dumbbell’s sway, monitored via a triaxial accelerometer, was modelled as an inverted pendulum pivoted at shoulder level. Twenty college students performed bilateral tests for 30 s using loads of 15 %, 25 %, and 35 % of a reference load determined as the mass measured by a scale placed under the hands during a quadruped position. The test was repeated 30 min and 24 h later. Time- and frequency-domain stabilometric parameters were computed using both the entire 30 s test duration and the first 20 s. ICC analysis revealed that the test as performed at 15 % of the reference load exhibited the highest intra- and inter-day reliability for both sides and durations, while reliability decreased at higher loads. Specifically, Jerk and swayArea exhibited good-to-excellent intra-day reliability (ICC = 0.866–0.947) and moderate-to-good inter-day reliability (ICC = 0.707–0.766), with 30 s test duration. All other stabilometric parameters showed moderate or moderate-to-good reliability (ICC > 0.5). The test provides a reliable, accessible, and ecologically valid assessment of shoulder sensorimotor control, with potential applications in clinical settings
Quality of Dying Among Institutionalised Nursing Home Residents From the Caregivers' Perspective: A Mixed-Methods Study
No full textAims To examine how family caregivers of deceased nursing home residents scored and justified their ratings for each item on the Quality of Dying in Long-Term Care scale and to identify the consistencies and discrepancies between their perceptions and the scores assigned when assessing the residents' end-of-life experience. Design A convergent mixed-methods design, comprising a cross-sectional study and a thematic analysis for quantitative and qualitative phases, respectively. Methods Quantitative and qualitative data were collected simultaneously between May 2018 and February 2019. The two sets of data were analysed separately. For the quantitative component, family caregivers completed the quality of dying in long-term care scale and a single-item question assessing the final month of the residents' life. Descriptive statistics, Mann–Whitney U-tests for comparative analyses and Spearman's correlations were applied to the quantitative data, while deductive thematic analysis was conducted for the qualitative data obtained through semi-structured interviews. Results Sixty-nine family caregivers completed the QoD-LTC, and 11 participated in qualitative interviews. The mean overall QoD-LTC score was 39.29 (SD = 7.58). The highest-rated domain was ‘Personhood’ (M = 4.32; SD = 0.68), while the lowest was ‘Preparatory Tasks’ (M = 2.66; SD = 1.26). Interviewed family caregivers reported effective management of pain and other symptoms, satisfaction with the care provided and respectful and appropriate treatment. However, they identified significant shortcomings in communication concerning end-of-life issues, coping with death and advance care planning. Residents with cognitive impairment had significantly lower scores on the ‘closure’ (p < 0.01) and ‘preparatory tasks’ (p = 0.03) domains as well as on the overall QoD-LTC score (p = 0.01). Conclusions and Implications The findings demonstrate consistency between the quantitative and qualitative data, with high scores reported across most domains of the QoD-LTC scale, with the exception of the ‘Preparatory Tasks’ domain. Cognitive impairment among residents was associated with lower perceived quality of the dying process from the perspective of family members.Objetivos Examinar cómo los cuidadores familiares de residentes fallecidos en residencias de ancianos puntuaron y justificaron sus valoraciones para cada ítem de la escala «Quality of Dying in Long-Term Care» e identificar las coincidencias y discrepancias entre sus percepciones y las puntuaciones asignadas al evaluar la experiencia del final de la vida de los residentes. Diseño Diseño convergente de métodos mixtos, que comprende un estudio transversal y un análisis temático para las fases cuantitativa y cualitativa, respectivamente. Métodos Los datos cuantitativos y cualitativos se recopilaron simultáneamente entre mayo de 2018 y febrero de 2019. Los dos conjuntos de datos se analizaron por separado. Para el componente cuantitativo, los cuidadores familiares completaron la escala Quality of Dying in Long-Term Care y una pregunta única que evaluaba el último mes de vida de los residentes. Se aplicaron estadísticas descriptivas, pruebas U de Mann-Whitney para análisis comparativos y correlaciones de Spearman a los datos cuantitativos, mientras que se realizó un análisis temático deductivo para los datos cualitativos obtenidos a través de entrevistas semiestructuradas. Resultados Sesenta y nueve cuidadores familiares completaron la escala QoD-LTC y 11 participaron en entrevistas cualitativas. La puntuación media global de la QoD-LTC fue de 39,29 (DE = 7,58). El dominio mejor valorado fue «Personhood» (M = 4,32; DE = 0,68), mientras que el más bajo fue «Preparatory Tasks» (M = 2,66; DE = 1,26). Los cuidadores familiares entrevistados informaron de un manejo eficaz del dolor y otros síntomas, satisfacción con la atención prestada y un trato respetuoso y adecuado. Sin embargo, identificaron deficiencias significativas en la comunicación sobre cuestiones relacionadas con el final de la vida, la aceptación de la muerte y la planificación anticipada de la atención. Los residentes con deterioro cognitivo obtuvieron puntuaciones significativamente más bajas en los ámbitos «clousure» (p < 0,01) y «preparatory tasks» (p = 0,03), así como en la puntuación global del QoD-LTC (p = 0,01). Conclusiones e implicaciones Los resultados demuestran la coherencia entre los datos cuantitativos y cualitativos, con puntuaciones altas en la mayoría de los ámbitos de la escala QoD-LTC, a excepción del ámbito «Preparatory Tasks». El deterioro cognitivo de los residentes se asoció con una menor percepción de la calidad del proceso de muerte desde la perspectiva de los familiares
La carta fuera de la carta: Análisis discursivo de los sobrescritos y márgenes en cartas del siglo XVI al XVIII
No full textEl estudio se centra en el análisis de cartas escritas entre los siglos XV y XVIII enfocado en las secuencias textuales que aparecen en los márgenes y los sobrescritos, las partes externas de la carta. El objetivo principal es investigar la función pragmática de estos textos marginales y su relación con variables sociopragmáticas y discursivas, así como realizar un análisis sintáctico-discursivo de las sobrescrituras y posdatas. Para ello, se analizaron las cartas privadas de cuatro corpus electrónicos: CenEFA, H15Corpus, Post Scriptum y CODEA+2022, los cuales permiten un acceso más fácil a documentos epistolares y aportan datos de emisión y recepción que sustentan el estudio sociolingüístico de los documentos.
La metodología se dividió en dos fases: un estudio cuantitativo que evaluó la caracterización sociolingüística de las cartas que contienen escritura en márgenes y sobrescritos y un análisis cualitativo que exploró la construcción sintáctica y discursiva de las secuencias textuales en función de su tipología. Los resultados revelaron que no existen factores sociolingüísticos que favorezcan claramente el uso de la supraescritura, aunque la preferencia por cada tipo de supraescritura sí se correlaciona con el registro y el tenor (familiar, negocial, cortesano), así como con la temporalidad por siglos. Además, se observó que la supraescritura es más común en cartas familiares, especialmente la escritura en márgenes y posdatas, la cual mantiene una sintaxis discursiva similar a la del cuerpo de la carta, con cierto nivel de complejidad sintáctica y un tono general coloquial.Este trabajo ha sido publicado gracias a la ayuda concedida por el Ministerio de Ciencia e Innovación y Universidades y la Agencia Estatal de Investigación (MICIU/AEI/10.13039/501100011033) al proyecto de investigación «Historia15: La escritura elaborada en español de la Baja Edad Media al siglo XVII: lengua epistolar y cambio lingüístico» (PID2020-113146GB-I00
General and left-continuous operators on lattice-based sums
No full textLattice-based sum provides a procedure to obtain posets and lattices from families of posets and lattices, respectively. Establishing sufficient conditions to ensure the lattice structure was the most significant challenge achieved in previous works. Next steps are to consider structures with general operators defined on the lattices of the family, introduce a sum of these operators on the obtained lattice-based sum and study the properties preserved by this new definition. We will prove that the natural definition preserve, in general, the monotonicity, associativity, commutativity, etc. This paper also introduces a new mechanism focused on preserving the left-continuity property of the operators defined on the lattices. This new approach also preserves the associativity and the infimum of non-empty subsets, and takes into account (infinite) complete lattices, unlike the previous works
Novel approach to extract epidemiological information from waves in epidemic's profiles
No full textIn this paper, we develop a novel mathematical framework based on the KermackMcKendrick model to extract epidemiological parameters from real temporal profiles
consisting of waves. The approach's key feature is the ability to obtain all model parameters from the geometry of the wave of interest.
We propose three new quantities to measure the negative impact of the epidemic wave on
a specific population, called Fraction of endemicity, Severity, and Asymmetry. These three
measures, along with a refined definition of the basic reproduction number, provide crucial
epidemiological information.
We demonstrate analytically that there is an equivalence among these quantities, and
such equivalence gives a way of obtaining all parameters in the model since the Asymmetry of a real epidemic wave is easily computed. This is the heart of the novel methodology we introduce. The framework is suitable for public health decision support, as its
implementation does not rely on complex mathematical tools.
We present several case studies to illustrate the simplicity of the framework as well as the
distinct aspects of its implementation. In all examples investigated, the numeric solution
obtained with the parameterized model shows good agreement with the available data.Consejería de Universidad, Investigación e Innovación - ERDF/EU — Andalusia Program (C-EXP-265-UGR23)MICIU/AEI/10.13039/501100011033 - ERDF/EU (PID2022-137228OB-I00
