- Abstract
The neutron time-of-flight facility n_TOF at CERN is a spallation source dedicated to measurements of neutron- induced reaction cross-sections of interest in nuclear technologies, astrophysics, and other applications. Since 2014, Experimental ARea 2 (EAR2) is operational and delivers a neutron fluence of ~ 4 · 107 neutrons per nominal proton pulse, which is ~50 times higher than the one of Experimental ARea 1 (EAR1) of ~ 8 · 105 neutrons per pulse. The high neutron flux at EAR2 results in high counting rates in the detectors that challenged the previously existing capture detection systems. For this reason, a Segmented Total Energy Detector (sTED) has been developed to overcome the limitations in the detector’s response, by reducing the active volume per module and by using a photo-multiplier (PMT) optimized for high counting rates. This paper presents the main characteristics of the sTED, including energy and time resolution, response to ¿-rays, and provides as well details of the use of the Pulse Height Weighting Technique (PHWT) with this detector. The sTED has been validated to perform neutron-capture cross-section measurements in EAR2 in the neutron energy range from thermal up to at least 400 keV. The detector has already been successfully used in several measurements at n_TOF EAR2., This work was supported in part by the I+D+i grant PGC2018- 096717-B-C21 funded by MCIN/AEI/10.13039/501100011033, by the European Commission H2020 Framework Programme project SANDA (Grant agreement ID: 847552) and by funding agencies of the n_TOF participating institutions., Article signat per 136 autors/es: V.

- Abstract
In this work, a program has been developed for the design of prequalified Simpson Strong-Tie Strong Frame type connections in accordance with the AISC regulatory requirements and within the prequalification and procedure limits contemplated in the ANSI/AISC 358-16 standard. To develop the program, was used the MATLAB software in its R2014a version, specifically its GUIDE environment for the design of the graphical interfaces and their respective programming. The program, called CONESTRONG (Simpson STRONG-Tie STRONG Frame Prequalified Connections), greatly facilitates the design of this type of connection, because it automatically verifies compliance with the various regulatory requirements and guides the user during the process with several suggestions. The results obtained with the program were compared with those of an example developed manually, with satisfactory results, En este trabajo se ha desarrollado un programa para el diseño de conexiones precalificadas tipo Simpson Strong-Tie Strong Frame de acuerdo a los requerimientos normativos AISC, y dentro de los límites de precalificación y procedimiento contemplados en la norma ANSI/AISC 358-16.

- Abstract
One of the critical aspects for the accurate determination of neutron capture cross sections when combining time-of-flight and total energy detector techniques is the characterization and control of systematic uncertainties associated to the measuring devices. In this work we explore the most conspicuous effects associated to harsh count rate conditions: dead-time and pile-up effects. Both effects, when not properly treated, can lead to large systematic uncertainties and bias in the determination of neutron cross sections. In the majority of neutron capture measurements carried out at the CERN n_TOF facility, the detectors of choice are the C6D6 liquid-based either in form of large-volume cells or recently commissioned sTED detector array, consisting of much smaller-volume modules. To account for the aforementioned effects, we introduce a Monte Carlo model for these detectors mimicking harsh count rate conditions similar to those happening at the CERN n_TOF 20 m flight path vertical measuring station. The model parameters are extracted by comparison with the experimental data taken at the same facility during 2022 experimental campaign. We propose a novel methodology to consider both, dead-time and pile-up effects simultaneously for these fast detectors and check the applicability to experimental data from 197Au(n, gamma), including the saturated 4.9 eV resonance which is an important component of normalization for neutron cross section measurements., This work has been carried out in the framework of a project funded by the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (ERC Consolidator Grant project HYMNS, with grant agreement No. 681740).

- Abstract
The cross section of the 89Y(n, ¿) reaction has important implications in nuclear astrophysics and for advanced nuclear technology. Given its neutron magic number N = 50 and a consequent small neutron capture cross section, 89Y represents one of the key nuclides for the stellar s-process. It acts as a bottleneck in the neutron capture chain between the Fe seed and the heavier elements. Moreover, it is located at the overlapping region, where both the weak and main s-process components take place. 89Y, the only stable yttrium isotope, is also used in innovative nuclear reactors. Neutron capture and transmission measurements were performed at the time-of-flight facilities n_TOF at CERN and GELINA at JRC-Geel. Resonance parameters of individual resonances were extracted from a resonance analysis of the experimental transmission and capture yields, up to a neutron incident energy of 95 keV. Even though a comparison with results reported in the literature shows differences in resonance parameters, the present data are consistent with the Maxwellian averaged cross section suggested by the astrophysical database KADoNiS., This research was funded by the European Community Seventh Framework Programme FP7/2007- 2011 under the Project CHANDA (Grant No. 605203), by the European Commission within HORIZON2020 via the EURATOM project EUFRAT for transnational access and by the funding agencies of the participating institutes., Article signat per 135 autors/es: G.

- Abstract
The Quintero-Puchuncaví Bay in Chile, has been affected by multiple episodes of anthropogenic contamination caused by companies in the Ventanas Industrial Corridor, making it one of the sacrifice zones in the country. On August 21, 2018, a mass poisoning of children and adolescents occurred, highlighting the dangers of contamination on the population's health at a national level. This qualitative narrative study explores this issue through the health trajectories of five families residing in the area. Information was gathered through family interviews, using art therapy strategies. A thematic narrative analysis of the data was conducted.The results reveal the presence of a range of illnesses spanning at least three generations of the interviewees' families. However, the long-term effects of contamination had not been fully acknowledged until the August 2018 incident, which made them aware of the generational transmission of normalizing this type of poisoning in their life paths. Additionally, the participants identify legal issues in controlling and reducing toxic emissions in the area., La Bahía de Quintero-Puchuncaví, Chile, ha sido afectada por múltiples episodios de contaminación antropogénica producidos por empresas del Cordón Industrial Ventanas, convirtiéndose en una de las zonas de sacrificio del país. El 21 de agosto de 2018 se produjo una intoxicación masiva de niños, niñas y adolescentes, evidenciando a nivel nacional los peligros de la contaminación en la salud de la población. El presente estudio cualitativo de tipo narrativo, explora esta problemática a partir de las trayectorias de salud de cinco familias que habitan el territorio. La técnica de producción de información consistió en entrevistas familiares, utilizando estrategias de arteterapia. Se realizó un análisis narrativo temático de los datos. Los resultados dan cuenta de la existencia de una serie de enfermedades en al menos tres generaciones de familiares de los entrevistados. Sin embargo, los efectos a largo plazo de la contaminación no habían sido plenamente aceptados hasta el episodio de agosto 2018, que los llevó a tomar consciencia de la transmisión generacional de la normalización de este tipo de envenenamiento en sus trayectorias vitales. Asimismo, los participantes identifican los problemas legales en el control y la reducción de emisiones tóxicas en el territorio.

- Abstract
The research investigates the subjective dimensions of social vulnerability of risk in inhabitants of areas exposed to flood hazards in Iquique, Chile, during the period 2019-2020. The methodology is qualitative with a case study design. The data are collected through semi-structured interviews, using the grounded theory coding process as an analysis strategy while the sample is made of 15 participants. The results are grouped into three categories: (1) actions against risk, (2) vulnerability to risk and (3) authority management. This information accounts for subjective conditions to which a differentiated evaluation is assigned, according to the perception of agentic characteristics/conditions of susceptibility and/or coping capabilities that a certain group has in a specific territorial area. Finally, the importance of promoting multidisciplinary interventions and studies that incorporate the subjective dimensions of the social vulnerability of risk, the characteristics of the territories, the environmental impact, the dangers and geological risks in the regulatory plans is postulated, which allow the authorities and communities to make better decisions in possible scenarios to promote and strengthen the understanding and reaction of communities in the post-disaster phase., Esta investigación tuvo como objetivo indagar las dimensiones subjetivas de la vulnerabilidad social del riesgo en habitantes de zonas expuestas a amenazas aluvionales en Iquique, Chile, durante el período 2019-2020. La metodología es cualitativa con un diseño estudio de caso, los datos son producidos mediante entrevistas semiestructuradas, utilizando como estrategia de análisis el proceso de codificación de la teoría fundamentada y la muestra son 15 participantes. Los resultados se agrupan en tres categorías: (1) acciones frente al riesgo, (2) vulnerabilidad ante el riesgo y (3) gestión de la autoridad. Esta información da cuenta de afecciones subjetivas a las que se le asigna una evaluación diferenciada, según la percepción de características/condiciones agenciales de susceptibilidad y/o capacidades de afrontamiento que posee un determinado grupo en una zona territorial específica. Finalmente, se postula la importancia de promover intervenciones y estudios multidisciplinarios que incorporen las dimensiones subjetivas de la vulnerabilidad social del riesgo, las características de los territorios, el impacto ambiental, los peligros y riesgos geológicos en los planos reguladores, lo cual permita a las autoridades y a las comunidades tomar mejores decisiones en posibles escenarios para promover y fortalecer la comprensión y reacción de las comunidades en la fase post-desastre.

The Hospital Management System Human Resource 1 is a web-based system that automatesand streamlines HR activities, including onboarding, recruiting, hiring, monitoring, andrecognizing employee performance. The traditional way of using email for communication canbe time-consuming and ineffective, leading to poor security measures and data loss, whichcan impact the daily operations of business. To address this issue, the project team developeda secure web-based system that simplifies the onboarding process and enables HRmanagers to track newly hired employees with ease. The system has enhanced securitymeasures to ensure the protection of HR 1 data, eliminating the need for complex andpaperwork-heavy processes. The system is designed to manage the version of HR 1 In HMSactivities and aims to make managing HR 1 less challenging for businesses. By breaking the project into manageable sprints and prioritizing tasks based on feedback, theteam delivered a web-based system that efficiently handles HR transactions for a hospital.This involved collaboration with HR personnel and stakeholders, quick delivery of a workingsystem, and ongoing improvement. Then, the team determines the most effective way toaddress the issues and improve the Hospital Management System Human Resource 1. The project aimed to improve Hospital Management System Human Resource 1 by reducingpaperwork, saving time, and ensuring data security while staffing the hospital effectively. Theteam developed a web-based system that efficiently monitors newly hired employees andproduces timely HMS HR 1 reports with minimal effort.

- Abstract
The average energy and multiplicity of prompt y -rays from slow neutron-induced fission of 235 U have been measured using the STEFF spectrometer at the neutron time-of-flight facility n_TOF. The individual responses from 11 NaI scintillators were corrected for multiple y -ray interactions, prompt fission neutrons and background counts before being deconvolved to estimate the emitted spectrum of prompt fission y -rays. The results give an average y -ray energy ¯Ey of 1.71(5) MeV and multiplicity ¯vy of 2.66(18) considering y -rays emitted within the energy range 0.8–6.8 MeV. The n_TOF data has a slightly larger ¯Ey and smaller ¯vy than other recent measurements, however the product of the two is in agreement within quoted uncertainties., This work was supported by the UK Nuclear Data Network, the BEIS Advanced Fuel Cycle programme, the SANDA Nuclear Data Euratom Project, and the funding agencies of the participating institutes., Article signat per 124 autors/es: T.

Introduction: The International Council of Cardiovascular Prevention and Rehabilitation (ICCPR) is developing a registry (ICRR) specifically for low-resource settings, where the burden of cardiovascular diseases is greatest and the need for program development highest. Herein we describe the development process, including the variable selection process. Method: Following a literature search on registry best practices, a stepwise model for ICRR development was identified. Then, based on recommendations by Core Outcome Set-STAndards for Development (COS-STAD), we underwent a process to identify variables. All available CR registries were contacted to request their data dictionaries, reviewed CR quality indicators and guideline recommendations, and searched for common data elements and core outcome sets; 35 unique variables (including patient-reported outcomes) were selected for potential inclusion. Twenty-one purposively-identified stakeholders and experts agreed to serve on a Delphi panel. Panelists rated the variables in an online survey, and suggested potential additional variables; A webcall was held to reach consensus on which to include/exclude. Next, panelists provided input to finalize each variable definition, and rated which associated indicators should be used for benchmarking in registry dashboards and a patient lay summary; a second consensus call was held. A 1-month public comment period ensued. Results: First, registry objectives and governance were approved by ICCPR, including data quality and access policies. The protocol was developed, for public posting. For variable selection, the overall mean rating was 6.1 ± 0.3/7; 12 were excluded, some of which were moved to a program survey, and others were revised. Two variables were added in an annual follow-up, resulting in 13 program and 16 patient-reported variables. Legal advice was sought to finalize ICRR agreements. Ethics approvals were obtained. Usability testing is now being initiated. Conclusion: It is hoped this will serve to harmonize CR assessment internationally and enable quality improvement in CR delivery in low-resource settings.

Restoring damaged β-cells in diabetic patients by harnessing the plasticity of other pancreatic cells raises the questions of the efficiency of the process and of the functionality of the new Insulin-expressing cells. To overcome the weak regenerative capacity of mammals, we used regeneration-prone zebrafish to study β-cells arising following destruction. We show that most new insulin cells differ from the original β-cells as they coexpress Somatostatin and Insulin. These bihormonal cells are abundant, functional and able to normalize glycemia. Their formation in response to β-cell destruction is fast, efficient, and age-independent. Bihormonal cells are transcriptionally close to a subset of δ-cells that we identified in control islets and that are characterized by the expression of somatostatin 1.1 (sst1.1) and by genes essential for glucose-induced Insulin secretion in β-cells such as pdx1, slc2a2 and gck. We observed in vivo the conversion of monohormonal sst1.1-expressing cells to sst1.1+ ins + bihormonal cells following β-cell destruction. Our findings support the conclusion that sst1.1 δ-cells possess a pro-β identity enabling them to contribute to the neogenesis of Insulin-producing cells during regeneration. This work unveils that abundant and functional bihormonal cells benefit to diabetes recovery in zebrafish.

Physics ,QC1-999 - Abstract
At the RIKEN Nishina Center, exotic neutron-rich isotopes of Ba, La, Ce, Pr, and Nd were measured. This work reports their half-lives (T1/2) and β-delayed neutron-emission probabilities (Pxn). The setup consisted of the BigRIPS in-flight separator for particle identification, the Advanced Implantation Detector Array (AIDA) for ions and β detection, and the BRIKEN neutron counter for neutron detection. Using this arrangement, 4 new T1/2 and 14 new P1n were measured. Furthermore, 38 T1/2 and 2 P1n values were remeasured, decreasing the uncertainties for some of them. In addition to improving predictions of nucleosynthesis models that describe the production of the rare-earth peak at A ∼ 160 via the r-process, these additional experimental data should help to constrain theoretical models for calculations of T1/2 and Pxn in this region.

Accurate neutron capture cross section data for minor actinides (MAs) are required to estimate the production and transmutation rates of MAs in light water reactors, critical fast reactors like Gen-IV systems, and other innovative reactor systems such as accelerator driven systems (ADS). In particular, 244Cm, 246Cm and 248Cm play a role in the transport, storage and transmutation of the nuclear waste of the current nuclear reactors, due to the contribution of these isotopes to the radiotoxicity, neutron emission, and decay heat in the spent nuclear fuel. Also, capture reactions in these Cm isotopes open the path for the formation of heavier elements. In this work, the results of the capture cross section measurement on 244Cm, 246Cm and 248Cm performed at the CERN n_TOF facility are presented. It is important to notice that the Cm samples used in the experiment at n_TOF have been used previously in an experiment at J-PARC, this experiment and the previous one done in the 70s with a nuclear explosion were the only previous capture experiments for these isotopes. At n_TOF, the capture cross section measurements of 244Cm, 246Cm and 248Cm were performed at the 20 m vertical flight path (EAR2) with three C6D6 total energy detectors. In addition, the cross section of 244Cm was measured at the 185 m flight path (EAR1) with a Total Absorption Calorimeter (TAC). The combination of measurements in EAR1 and EAR2 has contributed to controlling and reducing the systematic uncertainties in the results. The compatibility of the different measurements performed and the techniques to obtain the results are presented in this paper as well as the procedure to obtain the resonance parameters.

Physics ,QC1-999 - Abstract
The neutron capture cross section of 241Am is an important quantity for nuclear energy production and fuel cycle scenarios. Several measurements have been performed in recent years with the aim to reduce existing uncertainties in evaluated data. Two previous measurements, performed at the 185 m flight-path station EAR1 of the neutron time-of-flight facility n_TOF at CERN, have permitted to substantially extend the resolved resonance region, but suffered in the near-thermal energy range from the unfavorable signal-to-background ratio resulting from the combination of the high radioactivity of 241Am and the rather low thermal neutron flux. The here presented 241Am(n,γ) measurement, performed with C6D6 liquid scintillator gamma detectors at the 20 m flight-path station EAR2 of the n_TOF facility, took advantage of the much higher neutron flux. The current status of the analysis of the data, focussed on the low-energy region, will be described here.

Physics ,QC1-999 - Abstract
The slow neutron capture process (s-process) is responsible for producing about half of the elemental abundances heavier than iron in the universe. Neutron capture cross sections on stable isotopes are a key nuclear physics input for s-process studies. The 72Ge(n, γ) Maxwellian-Averaged Cross Section (MACS) has an important influence on the production of isotopes between Ge and Zr in the weak s-process in massive stars and so far only theoretical estimations are available. An experiment was carried out at the neutron time-of-flight facility n_TOF at CERN to measure the 72Ge(n, γ) reaction for the first time at stellar neutron energies. The capture measurement was performed using an enriched 72GeO2 sample at a flight path length of 184 m, which provided high neutron energy resolution. The prompt gamma rays produced after neutron capture were detected with a set of liquid scintillation detectors (C6D6). The neutron capture yield is derived from the counting spectra taking into account the neutron flux and the gamma-ray detection efficiency using the Pulse Height Weighting Technique. Over 70 new neutron resonances were identified, providing an improved resolved reaction cross section to calculate experimental MACS values for the first time. The experiment, data analysis and the new MACS results will be presented including their impact on stellar nucleosynthesis, which was investigated using the post-processing nucleosynthesis code mppnp for a 25 solar mass model.

Physics ,QC1-999 - Abstract
Radiative neutron-capture cross sections are of pivotal importance in many fields such as nucle-osynthesis studies or innovative reactor technologies. A large number of isotopes have been measured with high accuracy, but there are still a large number of relevant isotopes whose cross sections could not be experimentally determined yet, at least with sufficient accuracy and completeness, owing to limitations in detection techniques, sample production methods or in the facilities themselves. In the context of the HYMNS (High-sensitivitY Measurements of key stellar Nucleo-Synthesis reactions) project over the last six years we have developed a novel detection technique aimed at background suppression in radiative neutron-capture time-of-flight measurements. This new technique utilizes a complex detection set-up based on position-sensitive radiation-detectors deployed in a Compton-camera array configuration. The latter enables to implement gamma-ray imaging techniques, which help to disentangle true capture events arising from the sample under study and contaminant background events from the surroundings. A summary on the main developments is given in this contribution together with an update on recent experiments at CERN n_TOF and an outlook on future steps.

Physics ,QC1-999 - Abstract
Neutron cross section measurements are often made relative to a neutron cross section standard. Thus, the accuracy of the neutron standards determines the best possible accuracy of the neutron measurements. The 235U(n,f) cross section is widely used as reference, while it is considered a standard at thermal point and between 0.15 to 200 MeV. For this reason, additional cross section data for the 235U(n,f) reaction are useful in order to improve the accuracy and to extend the energy range of the standard. In this work, preliminary results of the measurement of the 235U(n,f) cross-section relative to the standard 10B(n,a) reaction are presented. The high accuracy measurement was performed at the experimental area EAR-1 of the n_TOF facility at CERN, aiming at covering the energy range from the thermal region up to approximately 100 keV. The samples were produced at JRC-Geel in Belgium, while the experimental setup was based on Micromegas detectors.

Neutron capture cross section measurements of isotopes close to s-process branching-points are of fundamental importance for the understanding of this nucleosynthesis mechanism through which about 50% of the elements heavier than iron are produced. We present in this contribution the results corresponding to the high resolution measurement, for first time ever, of the 80Se(n, γ) cross section, in which 98 resonances never measured before have been reported. As a consequence, ten times more precise values for the MACS have been obtained compared to previous accepted value adopted in the astrophysical KADoNiS data base.

Physics ,QC1-999 - Abstract
The neutron time-of-flight facility n_TOF is characterised by its high instantaneous neutron intensity, high-resolution and broad neutron energy spectra, specially conceived for neutron-induced reaction cross section measurements. Two Time-Of-Flight (TOF) experimental areas are available at the facility: experimental area 1 (EAR1), located at the end of the 185 m horizontal flight path from the spallation target, and experimental area 2 (EAR2), placed at 20 m from the target in the vertical direction. The neutron fluence in EAR2 is ˜ 300 times more intense than in EAR1 in the relevant time-of-flight window. EAR2 was designed to carry out challenging cross-section measurements with low mass samples (approximately 1 mg), reactions with small cross-sections or/and highly radioactive samples. The high instantaneous fluence of EAR2 results in high counting rates that challenge the existing capture systems. Therefore, the sTED detector has been designed to mitigate these effects. In 2021, a dedicated campaign was done validating the performance of the detector up to at least 300 keV neutron energy. After this campaign, the detector has been used to perform various capture cross section measurements at n_TOF EAR2.

The NEAR Station is a new experimental area developed at the n_TOF Facility at CERN. The activation station of NEAR underwent a characterization of the beam following the installation of the new n_TOF Spallation Target. The commissioning of the neutron beam comprises a set of simulations made with the FLUKA code and experimental verification. The experimental determination of the neutron spectrum was made using activation techniques with three separate set-ups. Two set-ups were based on the Multi-foil Activation technique (MAM-1 and MAM-2), and the third set-up relied on the process of neutron moderation and activation of a single material (ANTILoPE). The three set-ups are presented. Also the present plans and future perspectives of the activation station of NEAR are discussed.

Physics ,QC1-999 - Abstract
The n_TOF facility hosts CERN’s pulsed neutron source, comprising two beam lines of different flight paths and one activation station. It is based on a proton beam delivered by the PS accelerator impinging on a lead spallation target. During Long Shutdown 2 (LS2) at CERN (2019-2021), a major upgrade of the spallation target was carried out in order to optimize the performances of the neutron beam. Therefore, the characteristics of n_TOF two experimental areas were investigated in detail. In this work, the focus is on the second experimental area (EAR2), located 20 m above the spallation target. Preliminary results of the neutron energy distribution and beam line energy resolution are presented, compared to previous experimental campaigns and Monte Carlo simulations with the FLUKA code. Moreover, preliminary results of the spatial beam profile measurements are shown.

Physics ,QC1-999 - Abstract
Several international agencies recommend the study of new routes and new facilities for producing radioisotopes with application to nuclear medicine. 177Lu is a versatile radioisotope used for therapy and diagnosis (theranostics) of cancer with good success in neuroendocrine tumours that is being studied to be applied to a wider range of tumours. 177Lu is produced in few nuclear reactors mainly by the neutron capture on 176Lu. However, it could be produced at high-intensity celeratorbased neutron facilities. The energy of the neutrons in accelerator-based neutron facilities is higher than in thermal reactors.Thus, experimental data on the 176Yb(n,γ) cross-section in the eV and keV region are mandatory to calculate accurately the production of 177Yb, which beta decays to 177Lu. At present, there are not experimental data available from thermal to 3 keV of the 176Yb(n,γ) cross-section. In addition, there is no data in the resolved resonance region (RRR). This contribution shows the first results of the 176Yb capture measurement performed at the n_TOF facility at CERN.

- Abstract
The validity of TOEIC Bridge™ scores as a measure of English language skill was examined from the standpoint of a unified concept of test validity. In this study, more than 6,000 test takers in 3 Latin American countries (Chile, Colombia, and Ecuador) took 1 form of the TOEIC Bridge test, and their scores were compared to additional information about the students (teacher judgments, self-assessments, and performance on other academic achievement measures). The evidence collected was generally quite consistent with the interpretation of TOEIC Bridge scores as indicators of the English language competencies for the students examined.

This paper introduces in full detail a methodology for the measurement of neutron yield and the necessary efficiency calibration, to be applied to the intensity measurement of neutron bursts where individual neutrons are not resolved in time, for any given moderated neutron proportional counter array. The method allows efficiency calibration employing the detection neutrons arising from an isotopic neutron source. Full statistical study of the procedure is descripted, taking into account contributions arising from counting statistics, piling-up statistics of real detector pulse-height spectra and background fluctuations. The useful information is extracted from the net waveform area of the signal arising from the electric charge accumulated inside the detector tube. Improvement of detection limit is gained, therefore this detection system can be used in detection of low emission neutron pulsed sources with pulses of duration from nanoseconds to up. The application of the methodology to detection systems to be applied for D-D fusion neutrons from plasma focus devices is described. The present work is also of interest to the nuclear community working on fusion by magnetic confinement and lasers, and working on neutron production by accelerators or similar devices., Comment: Submitted to Rev. Sci. Instruments

Introducción: en el contexto latinoamericano se está generando evidencia sobre el empleo de instrumentos derivados de la Clasificación Internacional del Funcionamiento, de la Discapacidad y de la Salud en psiquiatría y salud mental. Este estudio corresponde a la primera investigación de carácter explicativo en población con trastornos mentales graves en tres países de Sudamérica. El objetivo es determinar un modelo explicativo de discapacidad en una muestra de personas con trastornos mentales graves en contacto con servicios ambulatorios de psiquiatría en Chile, Colombia y Ecuador. Materiales y métodos: se llevó a cabo un estudio multicéntrico, observacional, correlacional, de corte transversal, a partir de un muestreo probabilístico en Colombia y un muestreo por conveniencia en Chile y Ecuador. En total, participaron 803 adultos con trastornos mentales graves, en contacto con servicios ambulatorios de psiquiatría en Concepción (Chile), Cali (Colombia) y Quito (Ecuador). Resultados: el 91.3 % de la muestra presentó algún grado de discapacidad. El modelo multivariado final incluyó las variables explicativas país (Colombia; β=6.724); edad (β=−0.163); escolaridad (β=−0.5029); síntomas actuales de depresión (β=23.26); episodio psicótico (β=4.795); episodio hipomaniaco/maniaco (β=7.498; t=3.711); tener práctica religiosa (β=−2.834), y tener cuidador (β=10.363). Obtuvo un coeficiente de determinación de 0.3275 (F [23, 760]=16.09; p < 0.001, R2∆=30.71), que explica el 32.75% de la discapacidad de las personas de la muestra de los tres países participantes. Conclusiones: en un modelo multivariado de discapacidad para trastornos mentales graves, los síntomas actuales y la presencia de cuidador son las principales variables explicativas de discapacidad.

Science - Abstract
The functional significance of start site choice in promoter architectures is little understood. Here the authors identify in zebrafish development and mammalian cells a class of dual-initiation promoters, in which non-canonical YC dinucleotides reflecting 5’-TOP/TCT initiation are intertwined with canonical YR-initiation.

Objetivo: Este artículo plantea un análisis crítico sobre la Educación Especial en contextos de diversidad cultural confrontando supuestos teóricos asociados al enfoque médico, la teoría del etiquetamiento y perspectiva de poder. Método: El análisis se desarrolla a través de la revisión de literatura científica y normativa nacional e internacional, empleando un método documental-descriptivo. La recuperación de documentos se realizó desde las bases de datos Web of Science, Scopus y Scielo. Estrategias: Un análisis de los documentos recuperados ha permitido establecer que la Educación Especial en contextos de diversidad cultural podría constituir un dispositivo de control para homogeneizar a la población escolar, lo que se realiza a través de un sistema de clasificación y etiquetado, donde se utilizan procedimientos como el examen y el diagnóstico, en base a estándares aplicados por el grupo dominante. Originalidad: El artículo contribuye a la problematización de la educación especial en contextos educativos interculturales para avanzar hacia respuestas educativas culturalmente pertinentes. Se puede concluir que, tanto en Latinoamérica como en la región de La Araucanía se requiere repensar la Educación Especial desde nuevos marcos epistemológicos -como la interculturalidad crítica- que permitan reconocer y valorar la diversidad cultural.
