Rescaled-expansive flows: unstable sets and topological entropy
Authors: Arbieto Alexander , Artigue Alfonso , Rego Elias
Published: February 2025

In this work, we introduce and explore a rescaled theory of local stable and unstable sets for rescaled-expansive flows and its applications to topological entropy.
We introduce a rescaled version of the local unstable sets and the unstable points.
We find conditions for points of the phase space to exhibit non-trivial connected pieces of such unstable sets.
We apply these results to the problem of proving positive topological entropy for rescaled-expansive flows with non-singular Lyapunov stable sets.
Some existence results for nonresonant difference equations on infinite intervals subject to nonlocal boundary conditions
Authors: Maroncelli Daniel , Rodríguez Jesús
Published: February 2025

In this work we provide conditions for the existence of solutions to nonlinear boundary value problems of the form
\begin{equation*}
x_{k+1}=A_kx_k+f(k,x_k), \quad k\in\N_0:=\{0,1,\dots\},
\end{equation*}
subject to boundary conditions
\begin{equation*}
\sum_{k=0}^\infty B_kx_k=G(x).
\end{equation*}
We will show that under appropriate assumptions on each $A_k$, $f$, each $B_k$, and $G$, $\ellp{n}$ solutions will exist for $p\in [1,\infty]$.
Brézis-Kato type regularity results for higher order elliptic operators
Authors: Siemianowski Jakub
Published: February 2025

We prove Brézis-Kato regularity type results for solutions of the higher order nonlinear elliptic equation
\[
L u = g(x,u)\quad\text{in }\Omega
\]
with an elliptic operator $L$ of $2m$ order with variable coefficients and
a Carathéodory function $g\colon \Omega\times \C\to\C$, where $\Omega\subset\R^N$ is an open set with $N > 2m$.

Authors: Ma Tiantian , Yang Congmin , Wang Zaihong
Published: February 2025

In this paper, we study the existence and multiplicity of periodic solutions for singular Duffing
equations $x''+g(x)=p(t)$. When $g$ satisfies one-sided Lipschitz
condition and the related time map satisfies oscillation property,
we prove that the given equation has infinitely many periodic solutions.
Role of partial functionals in the study of variational systems
Authors: Stan Andrei
Published: February 2025

Applying techniques originally developed for systems lacking a variational structure, we establish conditions for the existence of solutions in systems that possess this property but their energy functional is unbounded both above and below.
We show that, in general, our conditions differ from those in the classical mountain pass approach by Ambrosetti-Rabinowitz when dealing with systems of this type.
Our theory is put into practice in the context of a coupled system of Stokes equations with reaction terms, where we establish sufficient conditions for the existence
of a solution.
The systems under study are intermediary between gradient-type systems and Hamiltonian systems.
Methodologie der effektiven Leseförderung im DaF/DaZ- Unterricht:authentisch – interaktiv – motivierend.
Authors: Peter Claudia
Published: February 2025

Einerseits ist das Lesen eine der grundlegenden Kompetenzen im DaF-Unterricht. Andererseits liest die Jugend
– vor allem aufgrund der Digitalisierung – immer weniger Bücher. Die Lektüre literarischer Texte ist besonders
beim Fremdsprachenlernen wichtig, denn neuer Wortschatz ist nur im Kontext gut zu verstehen und zu behalten.
Bekanntlich braucht unser Gehirn beim Lernen immer praktische Anwendungen, Relevanz der Information, Motivation
und Zusammenhänge, damit neue Inhalte langfristig behalten werden (Grein 2021). Und gerade Fachleute im
Bereich Übersetzen und Dolmetschen sind auf gutes Gedächtnis, schnelle Vokabularaufrufzeiten und Flüssigkeit
beim Sprechen angewiesen. Lektüre ist besonders dafür geeignet, die Mündlichkeit oder Verbalität im Kontext
zu üben. Der vorliegende Beitrag schlägt eine gleichsam einfache wie innovative Form des interaktiven Einsatzes
von Lektüre vor, wobei die Lernenden die Möglichkeit haben, sich mit der Autorin ihrer deutschen Lektürebücher
zu treffen, um sie zu interviewen, über das Entstehen, den Inhalt und die Hintergründe einer gelesenen Lektüre
zu sprechen und mit ihr zusammen ein Probelesen zu erleben. Beschrieben werden einige Projekte, die innerhalb
dieses Ansatzes mit mehreren Bildungseinrichtungen durchgeführt wurden, um den Deutschunterricht sowohl in
Spanien als auch weltweit zu bereichern, zu beleben und zu fördern. Das persönliche Kennenlernen der Autorin von
Lektüren, die im DaF-Unterricht eingesetzt werden, sowie gemeinsame, interaktive Aktivitäten – sei es online oder
präsenz – erhöhen die Motivation der Deutschlernenden nachhaltig und tragen zum beschleunigten Lernprozess bei.
Etude des impacts des changements climatiques sur la ressource en eau dans les montagnes du prerif (Maroc).
Authors: Azagouagh Kawtar
Published: February 2025

Les changements climatiques impactent de façon significative la disponibilité des
ressources en eau: ce qui entraine un dérèglement des régimes naturels saisonniers
des cours d’eau ainsi que la réduction de la capacité de stockage au niveau des
nappes et des retenus des barrages. Le Maroc, en raison de sa position géographique
au sein du bassin méditerranéen, est l’un des pays les plus vulnérables aux variabilités
du climat. Dans les montagnes du Prérif, les sécheresses climatiques et par
conséquent hydrologiques pendant les dernières décennies, ont eu des
conséquences dramatiques non seulement sur les rendements agricoles, mais aussi
sur l’environnement physique et humain. Elles se sont traduites par une aridification
de ces milieux, ainsi que par un manque sévère de la ressource en eau au cœur de la
saison humide. En matière d’analyse des périodes sèches, ayant un impact très
négatif sur l’environnement prérifain, il parait bien évident que les sécheresses
récurrentes qui ont sévit dans la région depuis les années 80 sont marquées par une
intensité qui montre essentiellement un aspect cumulatif et récurrent des années
très déficitaire. De plus, des séquences sèches mensuelles ont été détectées,
notamment entre 1998 et 2001 avec une séquence de 30 mois secs et entre 2007 et
2008 avec une séquence de 24 mois secs. De même, les sécheresses absolues
intercalaires au cours de l’année agricole, alors assez fréquentes, reflètent une
perturbation des rythmes saisonniers. Ainsi, l’épuisement de la ressource en eau,
dans l’ensemble de la région, s’est traduit par une réduction flagrante des débits des
sources et des cours d’eau: voire un tarissement total de certaines sources.
Le présent papier se propose d’étudier, en se basant sur l’analyse des indicateurs
météorologiques et hydrologiques, les tendances à la baisse de la pluviométrie et
par conséquent la réduction flagrante de la ressource en eau et ses conséquences
sur l’environnement physique et humain de cette zone de la montagne rifaine.
L’approche adoptée se base sur une analyse décennale des données pluviométriques
et hydrologiques des différentes stations de la région (recherche de tendance et de
cycle) ainsi que sur l’utilisation de l’Indice Standardisé de Précipitation (SPI) et
l’analyse des situations météorologiques à 500 hPa.
Coliving, ¿una alternativa habitacional? El caso de la ciudad de Málaga.
Authors: Romero-Padilla José , Romero-Padilla Yolanda
Published: February 2025

La dificultad de acceso a una vivienda en España motiva el surgimiento de nuevas
alternativas habitacionales. Este estudio analiza las implicaciones del fenómeno coliving en la ciudad malagueña. Para ello se ha revisado la literatura científica, portales
web de coliving, datos socioeconómicos y revisado su normativa. Todo ello junto a
una serie de entrevistas a expertos. Los resultados arrojan la ausencia de normativa
al respecto en España, siendo los jóvenes y nómadas digitales los que suelen ser el
público objetivo. La principal conclusión es que puede facilitar el acceso a la vivienda,
especialmente a los jóvenes y al establecimiento de nómadas digitales, dadas las
circunstancias actuales del mercado. Pero es imprescindible disponer de un marco
legal apropiado.

Till Tech Do Us Part: Betrayal Aversion and Its Role in Algorithm Use
Authors: Kormylo Cameron , Adjerid Idris , Ball Sheryl , Dogan Can
Published: February 2025

Failing to follow expert advice can have real and dangerous consequences. While any number of factors may lead a decision maker to refuse expert advice, the proliferation of algorithmic experts has further complicated the issue. One potential mechanism that restricts the acceptance of expert advice is betrayal aversion, or the strong dislike for the violation of trust norms. This study explores whether the introduction of expert algorithms in place of human experts can attenuate betrayal aversion and lead to higher overall rates of seeking expert advice. In other words, we ask: are decision makers averse to algorithmic betrayal? The answer to this question is uncertain ex ante. We answer this question through an experimental financial market where there is an identical risk of betrayal from either a human or algorithmic financial advisor. We find that the willingness to delegate to human experts is significantly reduced by betrayal aversion, while no betrayal aversion is exhibited toward algorithmic experts. The impact of betrayal aversion toward financial advisors is considerable: the resulting unwillingness to take the advice of the human expert leads to a 20% decrease in subsequent earnings, while no loss in earnings is observed in the algorithmic expert condition. This study has significant implications for firms, policymakers, and consumers, specifically in the financial services industry.

Linear Mean-Field Games with Discounted Cost
Authors: Saldi Naci
Published: February 2025

In this paper, we introduce discrete-time linear mean-field games subject to an infinite-horizon discounted-cost optimality criterion. At every time, each agent is randomly coupled with another agent via their dynamics and one-stage cost function, where this randomization is generated via the empirical distribution of their states (i.e., the mean-field term). Therefore, the transition probability and the one-stage cost function of each agent depend linearly on the mean-field term, which is the key distinction between classical mean-field games and linear mean-field games. Under mild assumptions, we show that the policy obtained from infinite population equilibrium is [Formula: see text]-Nash when the number of agents N is sufficiently large, where [Formula: see text] is an explicit function of N. Then, using the linear programming formulation of Markov decision processes (MDPs) and the linearity of the transition probability in the mean-field term, we formulate the game in the infinite population limit as a generalized Nash equilibrium problem (GNEP) and establish an algorithm for computing equilibrium with a convergence guarantee.
Multidimensional Analysis of Conceptual Understanding of Integer Addition and Subtraction
Authors: Toxtle-Colotl Adriana , Nieto-Ruiz Eldon , Juárez-López José Antonio
Published: February 2025

The objective of this study is to analyze secondary school students' conceptual understanding of integer addition and subtraction. To achieve this, a test based on the multidimensional assessment approach Skills, Properties, Uses, and Representations (SPUR) was administered to 34 secondary school students selected through convenience sampling at a secondary school in Puebla, Mexico. The study employs a qualitative research methodology at a descriptive depth level. The analysis of student responses utilized basic descriptive statistics and the qualitative content analysis technique. Significant differences were found in the accuracy levels across the SPUR dimensions: skills (51.8%), properties (41.9%), uses (60.8%), and representations (20.6%). Students with a solid conceptual understanding of integer addition and subtraction demonstrated high accuracy levels in at least three dimensions. The main difficulties identified were the use of the negative sign and challenges in adding two negative integers. The SPUR approach is a viable alternative for multidimensionally analyzing and assessing conceptual understanding of integer addition and subtraction.
Intractable subdural effusion after decompressive craniectomy for traumatic brain injury: A case report
Authors: Lin Ming-Jian
Published: February 2025

BACKGROUND

Traumatic subdural effusion is a common complication of traumatic brain injury, especially after decompressive craniectomy (DC). For neurosurgeons, early diagnosis and timely treatment are particularly important, which can help improve patient prognosis and enhance quality of life.

CASE SUMMARY

A 47 year old male underwent DC for traumatic brain herniation. After surgery, he developed stubborn subdural effusion (SDE) on the contralateral side and underwent multiple subdural drilling and drainage surgeries, but only temporarily improved the patient’s symptoms. After the final cranioplasty, the contralateral SDE completely disappeared. The patient did not experience any new contralateral neurological dysfunction, and the Glasgow prognostic score was 11 points (E4V1M6).

CONCLUSION

For neurosurgeons, accurate assessment of the condition is necessary when treating patients with stubborn SDE after DC surgery, and timely cranioplasty can be performed to avoid multiple surgeries. This is a safe and effective surgical method for treating traumatic subdural effusion.
Optical probing of fractal and multifractal connection to the degree of disorder strength in weakly optical disordered media: Application to cancer detection
Authors: Maity Santanu , Alrubayan Mousa , Apachigawo Ishmael , Solanki Dhruvil , Pradhan Prabhakar
Published: February 2025

The light scattering experiment establishes a relationship between refractive index fluctuations and fractal dimension in weakly scattering tissue-like media. Based on the box-counting approach, an analytical model is developed and shows that the fractal dimension has a functional dependency on the structural disorder or refractive index fluctuation for short-range correlation and approximately depends linearly on each other for tissue-like media. Several parametric imaging systems can be connected using this approach. Furthermore, tissue's weak multifractality optical scattering is explored using the box-counting method. It is shown that with a functional transformation, the distribution follows a lognormal distribution.
Contribution of genomic variation to the severity of multiple sclerosis
Authors: Kulakova O. G. , Matveeva N. A. , Kiselev I. S. , Boyko A. N. , Favorova O. O.
Published: February 2025

Multiple sclerosis (MS) is a chronic autoimmune disease of the central nervous system of polygenic nature, characterized by focal inflammation, demyelination and neurodegeneration. The clinical course of MS is characterized by great heterogeneity. The consistency of the clinical forms of MS in families indicates the involvement of genomic variation in the development of the clinical phenotype. Identifying the genetic basis of MS progression may not only explain the nature of the observed clinical heterogeneity but also contribute to the development of new tools for appropriate prognosis and personalized treatment of the disease. To describe the clinical course of MS, disease severity scores are used; they characterize the degree (speed) of MS progression. The most important methods for assessing the severity of MS are based on the Multiple Sclerosis Severity Score (MSSS) and Age-Related Multiple Sclerosis Severity Score (ARMSS) scales. This review summarizes the data on the contribution of polymorphic genetic variants to MS severity as assessed by the MSSS and ARMSS scales. These data were obtained using the "candidate gene" method and genome-wide association studies.
Enhancing Cancer Diagnosis
Authors: Maolood Ismail Y.
Published: February 2025

Early diagnosis of cancer is crucial for improved patient results. With the aim of improving the effectiveness of cancer diagnosis, this paper introduces a new proposed method, computer-aided diagnosis, utilizing the level-set algorithm based on the edge detection approach for medical image segmentation. To assess the performance of our method, it was proven on a highly varied dataset that comprised liver cancer, Magnetic Resonance Imaging (MRI) brain cancer, and dermoscopy color images. By effectively integrating edge information into the level-set evolution process, the proposed method achieved impressive results. For liver cancer images, we obtained an accuracy of 0.9913, a sensitivity of 0.9165, and a Dice coefficient of 0.8820. Similarly, for dermoscopy color images, the method achieved an accuracy of 0.9979, a sensitivity of 0.9301, and a Dice coefficient of 0.9301. In the case of MRI images, the method demonstrated an accuracy of 0.9933, a sensitivity of 0.8591, and a Dice coefficient of 0.8591. The proposed method outperforms traditional techniques such as Simulated Annealing combined with Artificial Neural Network and Fuzzy Entropy with Level Set thresholding. This method demonstrates superior segmentation accuracy and robustness. By enabling precise identification of cancerous regions, this approach supports early diagnosis, reduces misdiagnosis, and enhances treatment planning, offering significant potential for improving cancer care and patient results.

Published: February 2025

Much attention is presently focused on the vaccination with certain epitopes of an antigen. To further study the ability of neutralizing epitopes mapped in the first 1515 nucleotides of glycoprotein B of herpes simplex virus type-1 (gB-1) to induce neutralizing antibodies, a DNA immunization approach was employed. Vaccination of mice with a plasmid expressing the neutralizing epitopes induced humoral immune responses, although the antibody titre was significantly lower than that of antibodies induced by the full-length gB-1 gene. Furthermore, the plasmid DNA could not protect the mice against HSV-1 lethal challenge, but could significantly prolong the survival time compared to mock-vaccinated group.

Authors: Padma Priya M R , Sabir A A , Vijayalatha K R , Raja K , Geethanjali S
Published: February 2025

Solanum torvum, known as turkey berry, holds significant potential in introgression breeding, grafting technology, pharmaceuticals, and nanotechnology. However, the dormancy issue in Solanum torvum seeds must be addressed to utilize its potential fully. Various dormancy-breaking treatments, such as hot water soaking, scarification, stratification, and chemical and hormonal treatments, were applied at different concentrations and durations to enhance seed germination. Among the treatments, gibberellic acid at 1500 ppm for 24 hours showed the highest germination rate of 99 %. It also improved other seedling quality parameters, including root length (1.9 cm), shoot length (3.8 cm), dry matter production (3.9 g), vigour index I (574), vigour index II (386), and speed of germination (8.7). The findings from this study provide valuable insights into improving the germination of Solanum torvum seeds, which are crucial for their seed production and effective use in agriculture.

The 2024 Presidential Election Through Latino Lenses: Priorities and Vote Choice
Authors: Garcia-Rios Sergio I. , Gutierrez Angela E. , Ocampo Angela X. , Ocampo-Roland Angie N.
Published: February 2025

This paper examines the Latino vote in the 2024 U.S. Presidential election. We examine the factors that were most important for Latino voters and investigate how these shaped their candidate choice. Specifically, we argue that it is important to explore the demographic heterogeneity within the Latino category, as well as to explore the various issues that different subsets of the group prioritize. In doing so, we focus on differences by gender and socioeconomic status and explore how those impacted vote choice in the 2024 election. We rely on data from Texas and nationwide to examine these differences. We find that Latino men were more likely to vote for Trump compared to women. Similarly, we explore the role of issue prioritization, finding that Latinos who prioritize various economic issues and immigration were more likely to vote for Trump. On the other hand, Latinos who prioritize abortion were more likely to vote for Harris. We also find notable differences in how issue prioritization worked distinctively for women, men and those with and without a college degree. This paper underscores that Latinos are not an ideologically cohesive group and that the label of “Latino” should not operate to homogenize the group’s multifaceted interests. Instead, it gives us a better understanding of which specific issues were salient for different segments of the Latino community in 2024, and how these worked in particular ways to drive presidential candidate choice.
Energy drinks, depression, insomnia, and stress in palestinian adolescents: a cross-sectional study
Authors: Maraqa Beesan , Fasfoos Ahmad , Alami Mohammad , Banat Nader , Amr Obada , Saraheen Atef
Published: February 2025

Objectives

Adolescents are increasingly consuming energy drinks (EDs), prompting worries about their potential mental health impacts. The association between ED use and psychological effects among Palestinian teenagers, particularly the impact of smoking habits such as waterpipes, electronic cigarettes, and cigarettes, is little studied. This study explores the correlation between ED consumption and mental health outcomes such as depression, insomnia, and stress among adolescents in Palestine.

Methods

A cross-sectional study was conducted from February to June 2024, involving adolescents aged 12–18 recruited from schools in the West Bank. Data collection utilized a structured questionnaire assessing ED consumption, smoking habits, depression (PHQ-9), insomnia (ISI), and stress (Adolescent Stress Scale). Data were analyzed using SPSS version 29.

Results

The research involved 1,668 adolescents, with a mean age of 15.67 years (±1.57 years). ED consumption was prevalent at 74.7 % (95 % CI: 76.5–72.7). Males and smokers, especially those using traditional cigarettes and waterpipes, exhibited a higher likelihood of consuming energy drinks (aPR: 2.18; 95 %CI: 1.64–2.91), (aPR: 2.99; 95 %CI: 1.49–5.59), and (aPR: 2.54; 95 %CI: 1.23–5.19). Depression exhibited a significant relationship with ED consumption (aPR: 2.25; 95%CI: 1.51–3.37). A dose-response relationship was identified between insomnia and ED consumption, with an adjusted prevalence ratio (aPR) of 2.42 (95 % CI: 1.56–3.47) for moderate severity and 2.95 (95 % CI: 1.28–6.75) for severe insomnia.

Conclusions

ED consumption is associated with poorer mental health outcomes, particularly among smokers. Interventions targeting both ED use and smoking behaviors are crucial to improving mental health in Palestinian adolescents. The study was conducted during the Gaza war, a period marked by heightened stress levels among participants due to increased security checks and economic hardships. These challenges may have influenced participants’ stress levels and impacted their purchasing behaviors for EDs and tobacco shisha products. Further research is needed to explore the long-term effects of these behaviors.

Immobilienfinanzierung durch Markt und Regulierung belastet
Authors: Just Tobias , Wiersma Simon
Published: February 2025

Die aktuellen Verwerfungen auf den deutschen Immobilienmärkten sind in erster Linie durch die Zinswende und die steigenden Baukosten begründet: nach über zehn Jahren positiver Preisentwicklung sind Transaktions- und Finanzierungsvolumina seit dem zweiten Quartal 2022 rückläufig. Banken reagieren vorsichtig, die Beleihungsquoten bleiben trotz sinkender Preise niedrig, der Fokus verschiebt sich auf vermietete Objekte in innerstädtischen Lagen. Ermutigend sind die bislang anhaltend niedrigen Ausfallquoten bei Immobiliendarlehen, v. a. im Vergleich zu der Zeit nach der Finanz- und Wirtschaftskrise 2007/2008. Dies gilt insbesondere für Wohnimmobilien, doch für Gewerbeimmobilien nur mit leichten Einschränkungen ebenfalls. Der Neubausektor ist jedoch massiv belastet, da viel Fremdkapital benötigt wird und sowohl von Banken ausgegebenes Fremdkapital als auch Mezzanine-Kapital nicht in ausreichendem Umfang und nicht zu darstellbaren Kosten zur Verfügung steht. Besserung ist kurzfristig nicht in Sicht. Es stellt sich angesichts dieses Marktumfeldes die Frage, ob jüngste Regulierungsmaßnahmen für eine weitere Verschärfung der Situation sorgen könnten. Zu nennen sind hierbei die Kapitalunterlegung von 150 % für Projektentwicklungen und die Einführung eines sektoralen Systemrisikopuffers für die Finanzierung von Wohnimmobilien in Höhe von 2 % ab dem 01. Februar 2023. Da der Immobilienmarkt seinen zyklischen Höhepunkt bereits überschritten hatte, werden diese Maßnahmen wohl nicht die primär beabsichtigte antizyklische, sondern eine prozyklische Wirkung entfalten.
Sorgende Gemeinschaften – leibhaftige Spiritualität
Authors: Coenen-Marx Cornelia
Published: February 2025

Wenn es darum geht, Verantwortungsnetze auf regionaler und lokaler Ebene neu zu beleben, sind „Caring Communities“ zum internationalen Leitbegriff geworden. Dabei meint Care mehr als Versorgung oder Behandlung; es geht darum, das Leben und die Lebenszusammenhänge in vulnerablen Situationen aufrechtzuerhalten. Die Caring Communities von heute sind Gemeinschaften auf Zeit; aber sie erinnern an die diakonischen Gemeinschaften des 19. Jahrhunderts. Sie verknüpfen informelle Netzwerke, die von Austauschprozessen leben, mit formalen Organisationen, für die bezahlte Dienstleistungen konstitutiv sind. Ziel ist, chronisch kranke und pflegebedürftige Menschen als gleichberechtigtes Gegenüber, als „Nächste“ wahrzunehmen – nicht nur als Versorgungsfälle. Es geht darum, dass sorgende Gemeinschaften entstehen, in denen jeder in seiner Einzigartigkeit geachtet wird und dass die Sorgekräfte aller Beteiligten gestärkt werden.

In the UK, the British Cardiovascular Intervention Society represents and supports interventional cardiologists undertaking both coronary and structural interventions. Procedural data are collected in a national registry and these inform our understanding of UK practice and outcomes. These recommendations, pertaining to coronary intervention alone, are an update of those published in 2015 and describe the provision of percutaneous coronary intervention in the UK intended to provide optimal patient care.
Optimal recovery of mappings based on linear information with the help of $T$-splines in Banach spaces
Authors: Babenko V.F. , Babenko Yu.V. , Parfinovych N.V.
Published: February 2025

This work is dedicated to solving problems of optimal recovery of operator $A$ (not necessarily linear), defined on a subset $\mathfrak{M}$ of a Banach space $H$ using information  about elements of the $\mathfrak{M}$, given by a linear bounded operator $T\colon H\to Y$ where $Y$ is some Banach space. We show that under certain condition the optimal method of recovery is given by abstract interpolation splines in $H$ generated by $T$ ($T$-interpolating splines).
Some properties of the Generalized Jacobi polynomial
Authors: Waghela D. , Rao S.B.
Published: February 2025

An attempt is made to find recurrence relation and further properties of the generalized Jacobi polynomial $P_{n,\tau }^{\left( {\alpha ,\gamma ,\beta } \right)}(x)$ . Yet another generalization $P_{n,\tau ,\lambda }^{\left( {\alpha ,\gamma ,\beta } \right)}(x)$ of Jacobi polynomial $P_n^{\left( {\alpha ,\beta } \right)}(x)$ has been introduced and its properties have been studied. For $\lambda  = \tau$ we recover $P_{n,\tau }^{\left( {\alpha ,\gamma ,\beta } \right)}(x)$. The results so obtained may be useful in the theory of special functions, where Jacobi polynomials occur naturally.
Differences in cross-sectional and daily diary problematic pornography use correlates
Authors: Borgogna Nicholas C. , Vaughn Jacob , Owen Tyler , Brasil Kyle M. , Kraus Shane W. , Levant Ronald F. , McDermott Ryon C.
Published: February 2025

Background

Most problematic pornography use (PPU) research relies on cross-sectional designs. Ecological momentary assessment (EMA) studies are needed to better understand PPU correlates. We evaluated how daily PPU and pornography use ratings were correlated with baseline PPU, pornography use frequency (over 12-months), alcohol problems, and depression in a community sample of men living in the United States.

Design

Participants (n = 113, mean age 37.95 [11.09]) completed a baseline survey battery followed by daily EMAs over 14 days (k = 1,240 observations). Data were gathered on the Prolific panel.

Findings

Screener thresholds suggested 32%, 25%, and 24% of sample were at-risk for PPU, depression, and alcohol use problems respectively. Baseline estimates suggested PPU to be weakly correlated with depression (r = 0.29) and past 12-month pornography use (r = 0.27), but not alcohol problems (r = 0.08). Multilevel modeling indicated aggregated pornography use amount as a robust correlate of aggregated pornography control problems over the observation period. Baseline PPU and pornography use indicators were significant predictors of aggregated control problems and pornography use amount respectively. Baseline depression and alcohol problem predictors were non-significant. Past 12-month pornography use frequency and depression scores exacerbated the relationships between daily pornography use amount and aggregated control problems. Sensitivity analyses specific to only those who used pornography across all observations were consistent with full model results (though effect strength changed).

Conclusions

With exception to the PPU and pornography use indicators, cross-sectional baseline estimates (e.g., alcohol problems and depression) were generally not predictive of aggregated pornography use and control problems in the following 14 days.
A fordítás és a számítógép kapcsolata a többnyelvűség korában: kutatási trendek és eredmények
Authors: Prószéky Gábor
Published: February 2025

A számítógép már létrejöttekor kapcsolatban volt a fordítási feladattal, de csak a két nyelv közötti, tehát az egyetlen forrásnyelvből és egyetlen célnyelvből álló mondatpárokra koncentrált. Igaz, ekkortájt született meg az interlingva, azaz a közvetítőnyelv segítségével való többnyelvű fordítás gondolata, de a működő megoldások elmaradása miatt ez hosszú ideig csak absztrakt elképzelés maradt. Ezen az erősen kétnyelvű helyzeten a 20. század utolsó éveiben megjelent statisztikai rendszerek sem tudtak változtatni, mert a gyakoriságokon alapuló megközelítések szintén a forrásnyelvi-célnyelvi mondatpárokat helyezték a középpontba, amivel a többnyelvűséget pusztán kétnyelvű fordítások összekapcsolásaként vélték megvalósíthatónak. Az ok tehát mind a szabályalapú, mind a statisztikai rendszerek esetében a forrásnyelvi karaktersorozatból a célnyelvi karaktersorozatra való fordítás volt. A technológia további javulásával, de főleg a mesterséges intelligenciának nevezett gépi tanuló rendszerek előretörésével megjelentek a többé-kevésbé nyelvfüggetlen reprezentációk, és ezzel elkezdtek kialakulni a többnyelvűséget „alanyi jogon” kezelni képes számítógépes nyelvészeti rendszerek, melyek a gépi fordításban is új lehetőségeket hoztak. Az utóbbi években létrehozott többnyelvű fordítórendszerek minősége azt mutatja, hogy bár a fordítási feladat egy időben mindig két nyelv között zajlik, a „valódi” többnyelvűség megjelenése a nyelvtechnológiában új lehetőségeket hozott. Ezeket járja körül a tanulmány.
Az interprofesszionalitás jelentősége: milyen hatással van a fordítástudomány az orvostudományra?
Authors: Mány Dániel
Published: February 2025

Az orvostudomány mindig igyekezett ismereteit megosztani, a szakemberek és a laikusok számára hozzáférhetővé tenni. A tudományos ismeretszerzés forrása gyakran fordított szöveg, ezért a fordítás mint produktum hatással van a tudományos gondolkodásra, a betegségekhez vagy beavatkozásokhoz kapcsolt értékekre és véleményekre. A fordításban részt vevő különböző nyelvek és kultúrák azonban más céllal és nyelvi eszköztárral nevezhetnek meg tudományos fogalmakat, a megnevezések pedig egyfajta szociokulturális szimbólumként betekintést engednek az adott kultúra (tudományos) gondolkodásába. A fordítástudomány központi kérdése, hogy a fordító milyen stratégiákkal teremti meg a forrásnyelvi és a célnyelvi szöveg egyenértékűségét, funkcionális ekvivalenciáját. A globalizáció és a felgyorsult információáramlás önmagában rendkívül megnövelte az orvosi szakfordításra való igényt, amely még jelentősebbé vált a világszerte a figyelem központjába került koronavírus-válság és az újfajta egészségügyi diskurzusokat eredményező fegyveres konfliktusok által. A tanulmányban ismertetett kvalitatív, valamint kvantitatív módszerrel végzett kutatások eredményei megmutatják, hogy a fordítók milyen stratégiákkal teremtik meg a funkcionális ekvivalenciát, lehetővé téve ezáltal egyrészt a laikusok hatékony ismeretszerzését, másrészt az egészségügyi szakemberek jobb tájékozottságát, kutatási eredményeik széles körű disszeminációját és tudományos gondolkodásuk fejlesztését.

Aim of the study

This provides insight into the current and future water situation in the East Nile Delta in Egypt. Additionally, the study aimed to identify gaps in knowledge that require further research and to illustrate the different types of models used to optimize water resources management and maintain food security.

Material and methods

The study analyzed the status of water resources availability, water demand, and other influencing factors in the East Nile Delta. To address water scarcity, the study employed optimization models, specifically using linear optimization programming. This model was applied to the Eastern Delta area, focusing on the region supplied by the Ismailia Canal. The model aimed to balance the limited supply of freshwater with the increasing demand by proposing changes in cropping patterns.

Results and conclusions

The study found that the best way to secure water supply and minimize water scarcity is by using optimization models. In the Eastern Delta, the area supplied by the Ismailia Canal had a water deficit of about 789.81 MCM. By changing the cropping patterns, the water deficit could be reduced. The results indicated a decrease in the cultivation of non-strategic crops such as onions, garlic, fruit trees, peanuts, sesame, and soybeans. Conversely, there was an increase in the cultivation of strategic crops such as wheat, cotton, maize, and corn, as well as crops with high net yields like tomatoes and potatoes. These changes would help balance water demand and supply, ensuring a more sustainable water management strategy for the future.

Public health enhancement system in Russia includes a number of main components, one of which is measures aimed at increasing the population’s health literacy, creating a healthy lifestyle civility and a responsible attitude to health. An important social group of influence are women. Women's health literacy enables them to participate in health promotion activities and engage their communities in healthy lifestyles at local public level.

Aim. To study the health literacy level among "Woman — Health Model" project participants in the Yamalo-Nenets Autonomous Okrug.

Material and methods. An online survey of "Woman — Health Model" project participants aged ≥18 years was conducted using a validated and adapted HLS19-RUS questionnaire, developed on the basis of international questionnaire of World Health Organization Network on Measuring Population and Organizational Health Literacy (M-POHL). Health literacy (HL) was studied by means of standardized indices for four HL levels as follows: low, problematic, sufficient, excellent. Frequency analysis and associations of HL with socio-demographic characteristics of Yamal women. Also, navigational HL of women was studied for the first time. Statistical data processing was carried out using SPSS 23.0 for Windows and MS Excel 2016 software.

Results. Of the 2000 women participating in the Project, 1445 took part in the survey. The response rate was 72,25%. The results showed that 27,0% of participants had insufficient HL in disease prevention, assessment and use of health information. The most vulnerable groups were identified, which include women aged ≥65 years without higher education and job. Women participants in the Project from the YamaloNenets Autonomous Okrug encounter the greatest difficulties with regard to navigational HL (53,3%) — the ability to navigate services, changes, innovations and specialists of the healthcare system.

Conclusion. The results obtained made it possible to further adapt the training program for Project participants taking into account the identified level of HL and the difficulties women face in regard to health information.

Published: February 2025

Aim. Based on the generalization of Russian and international experience, to formulate the main types and components of preventive counseling (PC) of patients with risk factors for noncommunicable diseases, analyze existing programs and initiatives aimed at developing PC methods and technologies, including new ones, with subsequent implementation in primary health care (PHC). To identify and structure the main problems and barriers of the implementation of individual PC technologies in practice.

Material and methods. Systematic search and analysis of publications on the problem, systematization of the obtained information on the use of motivational, clinical and economic incentives for PC aimed at changing the population behavior on their own health.

Results. The main options/types and forms of PC are defined. Examples of successful implementation of short PC and in-depth PC technologies in primary health care practice are given. The following problems and barriers hindering the implementation of in-depth PC in primary health care were identified: insufficient training of health workers regarding communication skills and methods of motivational counseling; limited time for consultations; insufficient motivation of the patients themselves to change their lifestyle and comply with recommendations; management barriers associated with limited resources, the level of digital maturity of the medical organization and support from the healthcare system for the implementation of multifactorial medical prevention technologies.

Conclusion. The summarized factual data confirm the importance and necessity of introducing PC as an effective method for reducing modifiable risk factors for noncommunicable diseases. The most promising direction is in-depth PC, which, due to its targeted nature and comprehensive approach, allows achieving results in changing patients' behavior and reducing risk factors.
Risk factors and prevention of cardiovascular complications in breast cancer

Published: February 2025

Breast cancer (BC) is the most common malignant tumor in women. In patients who have undergone antitumor treatment at an early stage of BC, death in the long term more often occurs from cardiovascular diseases (CVD) than from cancer. Numerous studies indicate that the risk of cardiomyopathy and/or heart failure, coronary artery disease among BC survivors who received anthracyclines and/or trastuzumab is increased. Currently, early detection of cardiotoxicity using cardiac imaging and circulating cardiovascular biomarkers is widely evaluated in clinical trials. At the same time, the high risk of CVDs observed in cured breast cancer survivors is a consequence of both the adverse effects of anticancer therapy on the cardiovascular system, including antiestrogens, and the presence of common cancer and CVD risk factors. Large clinical trials reported higher rates of hypertension, hypercholesterolemia, and ischemic CVD in postmenopausal BC survivors receiving aromatase inhibitors. Strategies for the prevention and treatment of left ventricular dysfunction or heart failure in such patients should include a comprehensive cardiovascular risk evaluation and individual clinical assessment.

Aim. To study the effects of catheter renal denervation (RDN) on blood biomarker levels in patients with cardiovascular comorbidity and type 2 diabetes (T2D).

Material and methods. Sixty patients with true resistant hypertension (HTN) in combination with T2D and coronary artery disease after complete myocardial revascularization using percutaneous coronary intervention were included in a prospective observational non-randomized study. Patients were distributed in a 1:1 ratio into the intervention group and the control group. RDN was performed through femoral access using a Spyral system (Medtronic, USA). The primary endpoint was the change in plasma renin activity after 12 months. The results are presented as Me (Q25; Q75).

Results. In the intervention group, plasma renin activity significantly decreased from 4,65 (1,88; 7,79) to 2,21 (0,87; 5,49) ng/ml/h; angiotensin-I from 1,73 (0,34; 3,22) to 0,46 (0,31; 1,95) ng/ml; aldosterone from 131 (78; 173) to 118 (68; 153) pg/ml (p<0,05 for all). There were no significant changes in the control group. A decrease in office systolic and diastolic blood pressure was confirmed, with the greatest antihypertensive effect achieved in the high-renin hypertension group (renin activity at inclusion >6,5 ng/ml/h). The blood pressure decreases correlated with decrease in plasma renin activity (r=0,85; p<0,05). A significantly positive effect of RDN on reducing the levels of C-reactive protein, fasting glucose, glycated hemoglobin, and triglycerides was revealed (p<0,05 for all), without significant changes in the control group. The intervention and control groups did not statistically differ in the incidence of major adverse cardiovascular events, the glomerular filtration rate was comparable in both groups and did not change over time.

Conclusion. The use of RDN in comorbid patients is safe and allows for better control of modifiable risk factors for the progression of HTN and T2D due to an improvement of blood pressure, carbohydrate metabolism parameters, regulatory factors of the renin-angiotensin-aldosterone system, and factors of the systemic inflammatory response.
