Survey on the natural resistance to decay of five hundred tropical wood species
Authors: CANDELIER Kévin , GERARD Jean , THEVENON Marie-France , THIBAUT Bernard
Published: March 2024

The natural durability of wood species against rot has again become a matter of interest for the uses of wood as a natural material, while the use of synthetic fungicides is being debated. In the mid-20th century, many experimental studies were performed in Europe and North America, using different standardised protocols. More than five hundred tropical wood species were tested in France between 1955 and 1990, with a total of 9,842 wood samples tested. It would seem useful to allow free access to all the data from these tests in the interests of a more comprehensive study of the natural durability of large wood panels. The great majority (68%) of all these tests used two slightly different protocols with only a change in woodblock test dimensions. Roughly half of the species were tested under one of the two protocols, and the other half under the second. In addition, certain species were tested with both protocols. The dimensions of the test blocks, the fungal strain used, and the wood type (sapwood or heartwood) all give significantly different results, but the mean mass loss due to the 4 main fungal strains is a good predictor of the wood resistance to rot. Overall, mass loss for sapwood with each protocol is 45% higher than for heartwood of the same species. There is a significant positive correlation between the rot resistance of the sapwood and the heartwood, but the decrease in heartwood compared to sapwood is greater in durable wood species than in non-durable ones. Heartwood rot resistance was observed to be highly variable between trees of the same species, except in those classified as “very durable” and “non-durable”. This opens up possibilities for a classification of natural rot resistance for numerous useful types of timber that are often regarded as only moderately resistant because they include a small proportion of species with poor resistance. Each protocol group included over one hundred species for which density and chemical composition data were available. Density, lignin content, and extractive content have a similar and very significant influence on the rot resistance of the wood (R² around 0.25).

Un caso di deterioramento cognitivo associato ad escape virale in un paziente con infezione da HIV.
Authors: Mezzadri et al. Luca
Published: March 2024

Nonostante la significativa riduzione della mortalità globale tra le persone con HIV nell'era della terapia antiretrovirale combinata (cART), l'infezione cronica da HIV rimane associata a un'ampia gamma di disturbi neurocognitivi. Tale correlazione è attribuibile al marcato neurotropismo del virus, il quale infetta il sistema nervoso centrale (SNC) sin dalle prime fasi dell'infezione primaria. Tuttavia, altri fattori contribuenti includono comorbidità, invecchiamento precoce, vari tipi di demenza, disturbi psichiatrici ed il viral escape a livello del SNC. Quest’ultimo, caratterizzato da livelli rilevabili di HIV-RNA nel liquido cerebrospinale nonostante livelli non rilevabili o più bassi nel plasma, costituisce una sfida significativa nella gestione dell'HIV.
Nel presente caso clinico, descriviamo il quadro di un uomo con infezione da HIV la cui aderenza alla terapia era subottimale. Il paziente è giunto all’attenzione medica manifestando compromissione cognitiva, riconducibile infine a un caso di viral escape. La gestione si è rilevata particolarmente difficile a causa della necessità di selezionare un regime cART con maggiore penetrazione nel liquido cerebrospinale, considerando la sua storia di molteplici fallimenti virologici, mutazioni associate alla resistenza precedentemente rilevate e scarsa aderenza al trattamento.
Derecho de la competencia de la UE y mercado interior de la energía
Authors: García Coso Emiliano
Published: March 2024

Este artículo se centra en la aplicación de las normas de competencia de la UE como un instrumento complementario e imprescindible del marco regulatorio de la energía con el objetivo de garantizar y lograr el mercado interior de la energía. Las peculiaridades del mercado de la energía requieren ser exploradas desde su consideración como manifestaciones que pueden alterar los objetivos del Derecho de la competencia y, por ende, deben ser sometidas a la aplicación de su normativa, atendiendo a la casuística recaída en el mercado de la energía a la luz de las decisiones de la Comisión y del TJUE. Las características y los actores en el mercado interior de la energía revelan áreas de actuación que pueden encuadrarse dentro de los acuerdos y prácticas restrictivas de la competencia, de comportamientos que suponen un abuso de posición dominante en el mercado de la energía, con sistemas de ayudas públicas incompatibles con su régimen legal y con la realización de operaciones que pueden vulnerar el Reglamento de concentraciones.
La relación de los taxis-VTC y los conceptos autónomos del Derecho Europeo
Authors: Goñi Urriza Natividad
Published: March 2024

La legislación española que regula los servicios ejecutados por los taxis y las VTC han contenido tradicionalmente numerosas restricciones al acceso y al ejercicio de la actividad. La Sentencia del Tribunal de Justicia de la Unión Europea de 8 de junio de 2023 en el asunto Prestige & Limousine y AMB viene a derogar la posibilidad de condicional las autorizaciones de las VTC al número de las autorizaciones de taxis concedidas. Sorprendentemente, continúan confirmándose por los tribunales españoles esta y otras restricciones e introduciéndose nuevas medidas limitativas a favor del servicio del taxi y en claro perjuicio de otras empresas de transporte privado. El análisis de los conceptos europeos del Derecho de la Unión en materia de libre acceso y ejercicio de actividades económicas lleva a exigir una modificación de la jurisprudencia recaída sobre esta materia en los tribunales españoles, en general, y en el Tribunal Supremo, en particular.
La protección de los derechos digitales
Authors: Lazari Antonio
Published: March 2024

El almacenamiento de datos personales no pone en peligro solo el denominado derecho individual a la privacidad, sino que afecta a un espectro social y político más amplio, relacionado con la salud de la vida democrática. Frente a la visión soberanista china y a la idea segmentada y mercantilista estadounidense de seguridad digital, la Unión Europea va proponiendo en esta última década una concepción estrechamente ligada a la jurisprudencia del TJUE en torno a la esencia del derecho fundamental a la identidad digital. Este estudio aborda los aspectos esenciales de la protección de datos en la nueva globalización, diseñando un cuadro estratégico donde tanto dentro del territorio de la Unión como fuera de ello las instituciones comunitarias han de dialogar necesariamente sobre el alcance de los derechos fundamentales.
Alcance constitucional y europeo de la doble imposición
Authors: López Espadafor Carlos María
Published: March 2024

La doble imposición se presenta como un concepto impreciso, sin una delimitación legal general en el plano interno y que no goza de unos parámetros útiles que sirvan para limitarla. La evolución sufrida por el fenómeno de la doble imposición, tanto en el plano internacional, como en el plano interno, hace necesaria una revisión de tal concepto. La búsqueda de los parámetros jurídicos dentro de los cuales se pueda considerar legítimo o aceptable dicho fenómeno, hace necesaria la búsqueda de una concreción conceptual que resulte útil en tal sentido, para, a partir de la misma, poder redefinir los límites a las distintas formas de doble imposición. La redefinición de la doble imposición debe hacerse buscando una concreción útil de sus límites y alcance, que sirva para determinar cuándo es constitucional y cuándo acorde con los postulados del Derecho originario de la Unión Europea.
Bitcoin vs CBDC
Authors: Santaolalla Montoya Cayetana
Published: March 2024

El 12 de enero de 2023, el protocolo Bitcoin cumplió 14 años desde su puesta en marcha. El documento fundacional de Bitcoin (el Whitepaper) fue dado a conocer al mundo el 31 de octubre del 2008, por Satoshi Nakamoto**, quien desapareció para siempre el 10 de diciembre del 2010. En cada una de sus etapas a lo largo de más de 40 años de evolución, siempre estuvieron presentes en su estructura y su columna vertebral la libertad financiera del individuo, como derecho fundamental que tiene todo ser humano. Ahora, los Bancos Centrales, al albur del éxito y toma firme de posiciones del mercado criptográfico y económico por parte de la moneda creada por Satoshi, pretenden aplicar con premura y precipitación un programa de implantación paulatina en todo el mundo para sus monedas digitales, estrategia que llevan ya muy adelantada en países como China, Panamá o Nigeria. En este artículo se analizan las monedas digitales de los bancos centrales (CBDC-central bank digital cryptocurrencies), en contraposición a Bitcoin, con sus implicaciones jurídicas: la fe pública de la cadena de bloques, la jurisprudencia en torno a bitcoin, la (ausencia de) rendición de cuentas de los bancos centrales, los peligros de la centralización y la concentración de poder en la toma de decisiones, la pérdida de privacidad y anonimato, y la necesidad de hablar de un derecho en el ciberespacio.
La odisea judicial entre London Steam-Ship Owners-Mutual Insurance Association Limited y el Reino de España
Authors: Gómez Fasanella  Oriana , España Valenzuela Enrique de
Published: March 2024

El caso del Prestige, ha experimentado un extenso recorrido judicial. A lo largo de los años, los tribunales ingleses han emitido decisiones que contrarían con la sentencia del Tribunal Supremo Español. La más reciente sentencia del 6 de octubre del 2023 del Tribunal Superior de Justicia de Inglaterra y Gales agrega un nuevo capítulo a esta saga. El fallo sostiene que la sentencia del Tribunal Supremo Español, que ordenaba a London P&I Club pagar 855 millones de euros, es “incompatible” con las resoluciones arbitrales inglesas. Esta contradicción legal añade una capa adicional de complejidad al proceso, evidenciando la persistente incertidumbre en torno a la ejecución de decisiones judiciales y prolongando la incógnita sobre el desenlace final del caso Prestige.
La acción de reembolso ejercitada por una aseguradora se rige por la ley del lugar donde se ha producido el daño (comentario a la STJUE de 17 de mayo de 2023)
Authors: Ortega Giménez  Alfonso
Published: March 2024

El Tribunal de Justicia de la Unión Europea recientemente ha dictado una Sentencia en la que se pronuncia sobre la ley que se aplica en las acciones de reembolso por daños causados en un contexto internacional. Esta Sentencia, de fecha de 17 de mayo de 2023, concluye que una acción de reembolso ejercitada por una aseguradora, que ha abonado una determinada cantidad a una víctima de un accidente, contra el responsable del daño (o su aseguradora) se rige por la ley del lugar donde se ha producido el daño. Esta misma será la que determine, asimismo, el plazo de prescripción.
Civil meanings of child abduction. Analysis of a real case with two parties
Authors: Pizarro Moreno  Eugenio
Published: March 2024

There are not many occasions, neither from the investigative point of view nor from forensic practice, much less, as is the case, from both jointly, in which the jurist can study and try to resolve a case of child abduction.

The male parent has British nationality; the mother is a national of the Russia Federation. However, it can be said that this history of doctrine and jurisprudence lacked the necessary investigative interest if there had not been a minor, born in Spain, and whom her mother, without the knowledge or consent of her father,  transferred to Russia.

Thus begins a case that took us to the Court of Justice of the European Union. And, of course, to this research article than shows that between the formulation of a law or rules and its execution, there is always a pervasive chasm that not everybody is able to cross or knows how to do so.

Law is more a science of problems than of solutions, and it usually responds poorly -it cannot be otherwise- to facts with a markedly surprising nature.
Litigios sobre difamación por internet. Comentarios a la SAP Madrid 10 febrero 2023
Authors: Recuenco Pérez  Silvia
Published: March 2024

Los litigios sobre difamación cometidos en Internet presentan mayor complejidad que los cometidos por medios tradicionales. Entre otras cosas, porque los contenidos difamatorios pueden ser accesibles desde cualquier lugar del mundo. La ubicuidad de estos ilícitos afecta a cuestiones importantes de Derecho Internacional Privado, como es el hecho de que el demandante tiene hasta cuatro posibilidades de elegir foro. De esa elección dependerá que el juzgador pueda conocer sobre todos los daños sufridos en el mundo o sólo pueda resolver respecto de los daños causados en su territorio. Además, la elección del tribunal competente según un foro u otro condicionará al juzgador a estimar o desestimar las acciones de cesación. Así las cosas, el tribunal del país donde el actor decida presentar la demanda debe aplicar su propia norma de conflicto para determinar la ley aplicable al fondo del asunto. Esta ley resolverá cuestiones como la legitimación o la caducidad de la acción. Sobre estas cuestiones, la resolución comentada poco o nada trata.
O Conceito de Rapto Internacional de Crianças. Comentário à decisão da Audiência Provincial de Valencia de 8 de maio de 2023 [ECLI:ES:APV:2023:1178]
Authors: Sousa Gonçalves  Anabela Susana de
Published: March 2024

A deslocação ou retenção ilícitas de crianças é regulada internacionalmente pela Convenção de Haia de 1980 sobre os Aspetos Civis do Rapto Internacional de Crianças (Convenção de Haia). A Convenção de Haia de 1980 foi elaborada com o objetivo de proteger ou atenuar os efeitos da deslocação ou retenção ilícita através de fronteiras para as crianças, procurando garantir o regresso célere da criança ao país da sua residência habitual antes da deslocação, através de um sistema de cooperação entre autoridades centrais. A decisão da Audiência Provincial de Valencia, de 8 de maio de 2023, que comentamos, radica na existência, ou não, de uma situação de rapto internacional de crianças, ou de deslocação ou retenção ilícitas de crianças. Será este o conceito que iremos explorar.

COVID-19, Tattoos and How It Has Affected Locus of Control, Risk-Taking Behaviour, Self-Esteem and Body Image: A Quantitative Study
Authors: KONDHARE KUNAL DEVENDRA
Published: March 2024

This study explores how the covid-19 pandemic affected some psychological factors in people who got tattoos during or after the lockdown, the psychological factors assessed were self-esteem, risk taking behaviour, body image and locus of control. The study used a quantitative, between-subjects design to investigate the experiences of participants who acquired tattoos during the pandemic compared to those who did not. The results showed that participants who got a tattoo during the pandemic reported higher levels of self-esteem and body image satisfaction compared to those who did not get a tattoo. Furthermore, the findings suggest that individuals with tattoos may have a more external locus of control. Participants with tattoos exhibited higher levels of risk-taking behaviour compared to those without tattoos, furthermore sex affected risk-taking behaviour in tattooed individuals, and females with tattoos displayed a higher risk taking tendency than their tattooed male counterparts. Further research needs to be done while acknowledging the limitations of this study. Overall, this study is pivotal in establishing how the pandemic may have affected the aforementioned psychological factors in people with tattoos. It also adds to the growing body of literature in body modification and psychology.
Medical Support Vehicle Location and Deployment at Mass Casualty Incidents, Case Study: Mexico City
Authors: Medina-Pérez Miguel , Guzmán Giovanni , Saldana-Pérez Magdalena , Legaria-Santiago Valeria Karina
Published: March 2024

Anticipating and planning for the urgent response to large-scale disasters is critical to increase the probability of survival in these events. These incidents present various challenges that complicate the response, such as unfavorable weather conditions, difficulties in accessing affected areas, and the geographical spread of the victims. Furthermore, local socioeconomic factors such as insufficient prevention education, limited disaster assets, and inadequate coordination between public and private emergency services may complicate these situations. In large-scale emergencies, multiple hotspots are usually observed, which requires efforts to coordinate the strategic allocation of human and material resources in different geographical areas. Therefore, the precise management of these resources based on the specific needs of each area becomes fundamental. To address these complexities, this paper proposes a methodology that models these scenarios as an optimization problem, focusing on the location and allocation of resources in mass casualty incidents. The proposed case study is Mexico City in a post-earthquake scenario, using voluntary geographic information, open government data, and historical data from the September 19, 2017 earthquake. Additionally, it is assumed that the resources that require optimal location and allocation are ambulances, which focus on medical issues that affect the survival of victims. The designed solution involves the use of a metaheuristic optimization technique, along with a parameter tuning technique, to find configurations that perform at different instances of the problem, i.e., different hypothetical scenarios that can be used as a reference for future possible situations. Finally, the objective is to present the different solutions graphically, accompanied by relevant information to facilitate the decision-making process of the authorities responsible for the practical implementation of these solutions.
Differences in Environmental Investment Decisions of Heterogeneous Enterprises under Environmental Regulation: Based on the Perspective of Total Factor Productivity
Authors: Wang Bei , Chen Hong , Yang Zixiao , Liu Yuanxin , Wu Haoxue
Published: March 2024

This paper discusses the differential impact of environmental regulations on the environmental investment of heterogeneous firms. We find that (1) the impact of environmental regulations on the environmental investment of firms depends on the productivity level of the firms, and the higher the productivity of the firms, the greater the promotion effect of environmental regulations on the environmental investment of the firms. (2) As environmental regulations further increase the burden of environmental costs on firms, they are not conducive to expanding the production scale of low-productivity firms. (3) The higher the intensity of environmental regulation, the higher the productivity threshold for environmental investment by enterprises, and government fiscal expenditure can regulate the relationship between environmental regulation and the productivity threshold for environmental investment by enterprises.
Movement and Home Range of Amur Soft-Shell Turtle (Pelodiscus maackii) in the Ussuri River, Heilongjiang Province, China
Authors: Hou Xiaochen , Shi Hai-Tao
Published: March 2024

Comprehensively understanding the spatial ecology and habitat preferences of endangered species is essential for population restoration and conservation. We investigated the home range and movement of the endangered Amur soft-shell turtle (Pelodiscus maackii) in the Ussuri River, Heilongjiang Province, Northeastern China. The study involved tracking 19 Amur soft-shell turtles from late June to mid-October, 2022, resulting in complete and partial home range size data for eight subadults and two adults, respectively. The primary analysis focused on eight subadults, and the models that best described daily movement were identified. We also explored the potential factors influencing home range size. Mean movement rate ranged from 39.18 ± 20.04 m to 72.45 ± 29.36 m and was positively correlated with the linear home range and water temperature. The most insightful home range estimate was a 95% kernel density estimate, employing likelihood cross-validation smoothing with constraints set to the river boundaries. The mean home range size was 1.02 ha and was not correlated with body size. Subadults tended to establish well-defined home ranges over time; whereas, defining home ranges for adults proved challenging. This research addresses a gap regarding the ecology of the Amur soft-shell turtle and provides a foundation for future conservation plans.

Participación inclusiva de menores para frenar el deterioro democrático
Authors: Falck Andres , de la Rosa Miriam
Published: March 2024

La pandemia declarada en marzo de 2020 está dando lugar a una perturbación en las relaciones sociales. En este contexto, se manifiesta la tentación de buscar salidas autoritarias. En el presente texto argumentaremos que la evidencia empírica desacredita las soluciones verticales a la crisis. Por el contrario, esta puede ser una oportunidad para una reconstrucción participativa que, además, disminuya la desafección política. Proponemos hacer frente a las tendencias de involución democrática mediante fórmulas deliberativas con enfoque interseccional, activando procedimientos inclusivos de codecisión. De forma más concreta, describiremos una buena práctica participación con menores con una base de representación aleatoria, que ofrece un modelo útil para las metas propuestas.
Comparative study of coexistence problems among institutionalized elderly people versus senior classroom
Authors: Martínez-Ramón Juan Pedro
Published: March 2024

Institutionalized centers have become one of the most demanded alternatives as a home in which to spend the last stage of life due to the resources and services they offer. Traditionally, bullying among peers has been confined to the school environment; however, it is increasingly being shown that this phenomenon also occurs in other contexts. In this sense, several investigations have focused their attention on the phenomenon of bullying among older people. That said, the aim of this study was to compare bullying problems among users belonging to institutionalized centers with students in a classroom for the elderly. Participants were N = 80 elderly people (M = 73.23 years; SD = 11.18) with 63.7% being female. The Bullying Questionnaire adapted to Spanish was administered together with an ad hoc questionnaire to collect the sociodemographic characteristics in both groups. The results show a higher incidence of bullying in institutionalized centers, with social and verbal bullying being more common than physical bullying and cyberbullying. The conclusions revolve around the need to create bullying prevention and intervention programs among the elderly in community settings to improve their quality of life and promote active aging.
Overcoming Challenges in Technology Adoption: A Case Study in Fiber Optic Sensing
Authors: Hooper M. , Jalilian E. , Hull J.
Published: March 2024

Adoption of cutting-edge digitization tools in the energy sector is often challenged by an underestimation of value-in-use stemming from a lack of publicly available information regarding the breadth of technological capabilities and associated use-case economics. This paper seeks to address such challenges – as they pertain to advanced fiber optic sensing systems for monitoring of pipelines and other energy infrastructure - by providing readers with a comprehensive overview of the full range of operational applications and current economics for the state-of-the-art in the field, with a focus on case studies and value add benefits that have emerged more recently for many operators.

Distributed fiber optic sensing (DFOS) continues to see strong commercial growth in the Canadian energy sector, largely due to its exceptional suitability for real time detection of pinhole-level leaks along the full length of long-run pipeline assets. Combining the remarkable sensitivity and lightspeed transmission capabilities of DFOS with the analytical horsepower of the latest machine learning (ML) strategies allows pipeline operators to accurately detect and characterize even minute integrity events (like the pinhole leaks noted above) in real-time, regardless of when or where these occur within their vast asset networks. As a result, many operators have gained at least some familiarity with distributed fiber optic sensing (DFOS) systems and a basic understanding of their performance capabilities and general economics.

The downside of this singular focus on the leak detection capability and use case is, of course, that industry may elect not to adopt – or at a minimum fail to exploit the full potential of - this rapidly evolving technology, particularly as novel applications dramatically increase DFOS’ value in use. Rapid commercial growth has also driven down DFOS costs as deployment methods and system architectures are optimized over millions of pipeline meters, resulting in an often-substantial gap between perceived adoption cost and real project economics. This combination of capability underestimation and life-cycle cost overestimation presents a major challenge for many technology adoption scenarios, with analysis made all the more difficult by a general lack of publicly available project details.

This paper reviews case studies from recent DFOS deployments, with a focus on the operational value-in-use realized for a cross-section of commercial applications (i.e., pig tracking, real-time remediation support, temporary pipeline (‘layflat’) management, etc.) as well as the broader business case for life cycle technology costs (i.e., ROI metrics) aimed at providing an accurate understanding of both the costs and capabilities of advanced DFOS systems for integrity management of energy infrastructure. Ultimately the paper will help operators better understand the current state of DFOS technology and make informed decisions regarding its potential and business case to support their existing operations.
Construction of intelligent visual design system based on convolutional neural network under the background of big data
Authors: Geng Chunxia
Published: March 2024

In recent years, artificial intelligence has been initially applied to the visual design process, which has had a certain impact on the traditional design methods and working modes. Through the analysis of the working principle of the key technology of artificial intelligence design, the generation antagonism network (GAN), this paper summarizes the advantages and limitations of the existing automatic design methods, and puts forward the transformation path and specific methods of visual design working mode oriented to automation design efficiency optimization and new technology application form innovation under the background of new technology. With the rapid development of cloud computing and artificial intelligence, there are more and more applications in the cloud based on artificial intelligence as a service. Among them, artificial intelligence based on convolutional neural network is widely used. Convolution neural network endogenous control is the first fusion of endogenous security ideas in deep neural network model security control. Based on the core operation structure of convolutional neural network, the key control points of the endogenous control model are proposed; By tightly coupling the endogenous control unit at the control point, a convolutional neural network endogenous control model is designed and proposed.

Authors: naderi Malihe , Hosseini Seyed Masoud , Behnampour Naser , Shahramian Iraj , Moradi Abdolvahab
Published: March 2024

This study focused on detecting mutational patterns in the X-gene of the HBV genome in three-generations of CHB patients. Ninety CHB patients were analyzed, revealing the highest similarity in X-gene sequences between mothers and children in two-generations (79.3%). The N-terminal of the X-gene showed frequent mutations, with notable occurrences at positions C1491G (25%), C1500T (43.4%), G1613T (23.9%), and G1658T (33.4%). Mutations were more prevalent in HBeAg-negative patients, indicating a significant difference (P-value = 0.03). A1762T/G1764A mutations were present in 15.6% of patients, demonstrating significant relevance. These mutational patterns may aid in predicting clinical outcomes and identifying susceptibility to hepatocellular HCC in patients.
The status of academic interventional radiologists in Germany with focus on women: How can we do better?

Published: March 2024

Purpose
The aim was to characterize the framework conditions in academic interventional radiology (IR) in Germany with focus on differences between genders.
Materials and Methods
After IRB approval, all members of The German Society for Interventional Radiology and Minimally Invasive Therapy (n = 1,632) were invited to an online survey on work conditions in clinical and academic practice. The academic practice subset contained questions about research challenges: networking, funding, working hours and time spent with research. Statistical comparisons were undertaken with the Fisher's exact test, Wilcoxon rank sum test or Pearson's Chi-squared test.
Results
267 questionnaires were available resulting in a general response rate of 16.4%. Two-hundred of them were fully completed. 40% of these (78/200) were involved in academic IR (71% men vs. 29% women, p < .01) and were therefore eligible for further analysis. Of these, 6% worked part-time (2% vs. 17%, p < .05). 90% of them spent less than 25% of their research during their paid working hours, and 41% performed more than 75% of their research during leisure time. 28% received exemption for research. 88% were (rather) satisfied with their career. One in two participants successfully applied for funding, with higher success rates among male applicants (90% vs. 75%) and respondents with protected research time (93% vs. 80%). Compared to men, women rated their entrance in academic IR as harder (p < .05), their academic IR-career as more important (p < .05), felt less noticed at congresses (93% vs. 53%, p < .01), less confident (98% vs. 71%, p < .01), and not well connected (77% vs. 36%, p < .01).
Conclusion
Women and men did research under the same framework conditions; however, women were underrepresented. Future programs should generally focus on protected research and gather female mentors to advance academic IR in Germany.
Growth Differentiation Factor 15 (GDF15) Expression in the Heart After Myocardial Infarction and Cardioprotective Effect of Pre-Ischemic rGDF15 Administration

Published: March 2024

Clinical data consider growth differentiation factor-15 GDF15 as a prognostically unfavourable biomarker in cardiovascular diseases, while experimental studies suggest its cardioprotective potential. This study focuses on the direct cardiac effects of GDF15 during ischemia-reperfusion (I/R) injury in Wistar male rats, employing concentrations relevant to patients at high cardiovascular risk. Initially, we examined circulating levels and heart tissue expression of GDF15 in rats subjected to I/R and Sham operations in vivo. Subsequently, we evaluated the cardiac effects of GDF15 both in vivo and ex vivo, administering recombinant GDF15 either before ischemia (preconditioning) or at the onset of reperfusion (postconditioning). We compared infarct sizes and recovery of cardiac contractile parameters between control and rGDF15 treated rats. Contrary to our expectations, I/R did not elevate GDF15 plasma levels compared to Sham-operated rats. However, cardiac expression at both protein and mRNA levels increased in the infarcted zone of the ischemic heart after 24 hours of reperfusion. Notably, preconditioning with rGDF15 exhibited a cardioprotective effect, reducing infarct size both in vivo and ex vivo, while enhancing the recovery of cardiac contractile parameters ex vivo. However, postconditioning with rGDF15 did not alter infarct size or the recovery of contractile parameters either in vivo or ex vivo. These findings reveal, for the first time, that short-term exogenous administration of rGDF15 before ischemia, at physiologically relevant levels, protects the heart against I/R injury in both in vivo and ex vivo settings. The latter situation suggests that rGDF15 can operate independently of the inflammatory, endocrine and nervous systems, presenting GDF15 as a direct and potent cardioprotective properties against ischemia-reperfusion injury.

Forecasting floods encompasses significant complexity due to the nonlinear nature of hydrological systems, which involve intricate interactions among precipitation, landscapes, river systems, and hydrological networks. Recent efforts in hydrology have aimed at predicting water flow, floods, and quality, yet most methodologies overlook the influence of adjacent areas and lack advanced visualization for water level assessment. Our contribution is twofold: firstly, we introduce a graph neural network model equipped with a graph learning module to capture the interconnections of water systems and the connectivity between stations to predict future water levels. Secondly, we develop a simulation prototype offering visual insights for decision-making in disaster prevention and policy-making. This prototype visualizes predicted water levels and facilitates data analysis using decades of historical information. Focusing on the Greater Montreal Area (GMA), particularly Terrebonne, Quebec, Canada, we apply our model and prototype to demonstrate a comprehensive method for assessing flood impacts. By utilizing a digital twin of Terrebonne, our simulation tool allows users to interactively modify the landscape and simulate various flood scenarios, thereby providing valuable insights into preventive strategies. This research aims to enhance water level prediction and evaluation of preventive measures, setting a benchmark for similar applications across different geographic areas.

This study aimed to investigate the effect of the Perceived Media Value (PMV) on Trust in Media-based Brands (TMB). The study population consisted of all customers of Digikala's online store. The number of samples (n = 384) chosen through a random sampling process was obtained using Cochran's sample size formula. The data were collected using the PMV scale. The questionnaire reliability was confirmed by applying Cronbach's alpha. Structural Equation Modeling (SEM) was utilized in the data analysis with the help of AMOS and SPSS software. The PMV and its components (including information, entertainment, networking, and social status value) significantly positively affected TMB. In addition, social status, networking, information, and entertainment value had the strongest relationships with TMB, respectively.

Soil organic carbon (SOC) rapidly accumulates during ecosystem primary succession in glacier foreland. This makes it an ideal model for studying soil carbon sequestration and stabilization, which are urgently needed to mitigate climate change. Here, we investigated SOC dynamics in the Kuoqionggangri glacier foreland on the Tibetan Plateau. The study area along a deglaciation chronosequence of 170-year comprising three ecosystem succession stages, including barren ground, herb steppe, and legume steppe. We quantified amino sugars and lignin phenols to assess the contributions of microbial and plant residues to SOC, and used FT-ICR mass spectroscopy to analyze the composition of dissolved organic matter. We found that herbal plant colonization increased SOC by enhancing ecosystem gross primary productivity, while subsequent legumes development decreased SOC, due to increased ecosystem respiration from labile organic carbon inputs. Plant residues were a greater contributor to SOC than microbial residues in the vegetated soils, but they were susceptible to microbial degradation compared to the more persistent and continuously accumulating microbial residues. Our findings revealed the organic carbon accumulation and stabilization process in early soil development, which provides mechanism insights into carbon sequestration during ecosystem restoration under climate change.

On-chip integration of two-dimensional (2D) materials with unique structures and properties endow integrated devices with new functionalities and improved performance. With high flexibility in ways to modify its properties and compatibility with integrated platforms, graphene oxide (GO) is an exceptionally attractive 2D material for hybrid integrated photonic chips. Here, we demonstrate novel functionalities beyond the capability of photonic integrated circuits, by harnessing unique property changes induced by photo-thermal effects in 2D GO films. These include all-optical control and switching, optical power limiting, and non-reciprocal light transmission. The 2D layered GO films are integrated onto photonic chips with precise control of their thickness and size. Benefitting from the broadband optical response of 2D GO films, all three functionalities feature a very wide operational optical bandwidth. By fitting the experimental results with theory, we determine the changes in GO film properties induced by the photo-thermal effects, revealing interesting insights about the physics of 2D GO films. These results highlight the versatility of 2D GO films in implementing new functions for integrated photonic devices for a wide range of applications.

Objective:This study aim to evaluate the association between dietary vitamin C intake and the risk of migraine in adult individuals.
Methods: This cross-sectional study utilized data from the National Health and Nutrition Examination Survey (NHANES) conducted between 1999 and 2004. Logistic regression models, restricted cubic spline (RCS) regression, and stratified analyses were employed to assess the association between dietary vitamin C intake and migraine.
Results: This study included 4101 participants, of whom 702 (17.12%) experienced migraine. The study revealed an inverse association between dietary vitamin C intake and migraine risk (OR=0.89, 95% CI: 0.83-0.96, P=0.002) after adjusting for all covariates. When vitamin C intake was categorized, the adjusted OR (95% CI) for migraine risk in Q 4 (highest vitamin C intake ) was 0.64 (95% CI: 0.49-0.84, P=0.001) compared with Q1 (lowest vitamin C intake). The RCS regression showed a linear inverse relationship between dietary vitamin C intake and migraine risk (P for non-linearity=0.449). The findings remained consistent, and no significant interactions were found among different groups.
Conclusion: Dietary vitamin C intake was independently associated with migraine, and a linear negative relationship was found betweenvitamin C intake and the risk of migraine.

Astragalus membranaceus has important medicinal and ecological values, but with global changes, its growth is often negatively affected by abiotic stresses such as drought stress. The bZIP family transcription factors (TF) play important roles in plant growth and development, and the response to abiotic stresses. However, systematic identification of the bZIP gene family in A. membranaceus and their expressions under drought stress have not been reported. In the present study, genome-wide identification, chromosome localization, phylogenetic analysis, motif analysis and domain prediction of the bZIP family genes in A. membranaceus were performed. A total of 74 bZIP family members were identified in A. membranaceus, which are divided into 13 subfamilies, and members in each subfamily have similar gene structures and conserved motifs. The bZIP family members were unequally distributed on the 9 chromosomes of A. membranaceus. Four bZIP genes were generated via tandem duplication, including Am01G021190 and Am01G021150, and 45 were formed though segmental duplication. Compared with Zea mays and Oryza sativa, the bZIP genes of A. membranaceus have more collinearity with that of Medicago truncatula. The promoter analysis showed that the bZIP transcription factor family was rich in plant hormone response elements and abiotic stress response elements. The analysis of transcriptome data and qRT-PCR indicated that several bZIP TFs including AmZIP46 was involved in the response to drought stress. Further experiments showed that AmbZIP46 is only localized in the nucleus and has transcriptional activation activity. This study provided important data for understanding the biological functions of the bZIP family transcription factors in A. membranaceus.
