Research Insights: How Does Firm-Embedded Productivity Affect Cross-Country Income Differences?
Authors: Alviarez Vanessa , Cravino Javier , Ramondo Natalia
Published: January 2025

The gap in productivity among countries is a fundamental factor contributing to income disparities across countries. Firm-embedded productivity, encompassing knowledge, expertise, patents, brands, and business models, contributes to approximately one-third of the variation in output per worker across countries. Country-specific factors, such as institutions and natural resources, account for the remaining variation. Policies that enhance firm- embedded productivity, such as tax incentives for R&D and research grants, can help reduce global income inequality.
An Examination of Numerical Portability in Mobile Communication in Uruguay
Authors: Gandelman Néstor , Roldán Flavia , Viera Sofía
Published: January 2025

This paper examines the effects of the introduction of mobile number portability (MNP) using data from Uruguay. MNP allows customers to switch mobile providers while retaining their phone number, thereby reducing switching costs and potentially enhancing competition. Our analysis reveals that firms responded by increasing the share of postpaid contracts, partially countering the exogenous reduction in switching costs with new endogenous barriers. We find that while market concentration increased in terms of subscriber share, it decreased for data traffic, reflecting differing customer behaviors and firms' commercial strategies. Additionally, we observed reductions in mobile data prices and an increase in new mobile subscribers, suggesting that MNP contributed to overall market growth. Using a world panel of data prices for the internet we find that MNP is associated with lower prices in the range of 42-50 percent.

Published: January 2025

Efficient inventory management is pivotal for manufacturing companies striving to maintain operational excellence, minimize costs, and meet dynamic market demands. Traditional inventory management systems, while functional, often fall short in addressing complex supply chain challenges such as real-time visibility, demand variability, and integration with modern technologies. This study explores the development of an integrated inventory management model designed to optimize inventory control, enhance decision-making, and reduce operational inefficiencies. By leveraging advanced technologies, including IoT, AI, and ERP systems, the proposed model integrates demand forecasting, inventory optimization, and supplier collaboration into a cohesive framework. Data-driven insights and predictive analytics form the cornerstone of this approach, enabling manufacturing companies to adapt to shifting market conditions seamlessly. The research evaluates the model's performance through simulations and case studies, highlighting significant improvements in inventory turnover, cost reduction, and operational agility. This study provides a pathway for manufacturing companies to transition to scalable, efficient, and technologically advanced inventory management systems.
Słowotwórcze i leksykalne zróżnicowanie formacji wariantywnych na przykładzie gwarowych nazw człowieka, który stale kłamie
Authors: Marciniak-Firadza Renata
Published: January 2025

Gwary, stanowiące jedną z najbardziej reprezentatywnych odmian polszczyzny mówionej, okazują się szczególnie wdzięcznym polem dla badań słownictwa emocjonalnie nacechowanego, a to dlatego iż z jednej strony charakteryzują się większą różnorodnością środków językowych wykorzystywanych do tworzenia nazw ekspresywnych niż język literacki, z drugiej — mają nad polszczyzną ogólną przewagę tych formacji. Szczególnie bogaty materiał przynoszą nacechowane emocjonalnie, przeważnie negatywnie, nazwy dotyczące człowieka, bowiem ekspresja uczuć, ocen należy do tej sfery zachowań językowych, które ujawniają się w spontanicznych, bezpośrednich kontaktach międzyludzkich. Postępowanie człowieka podlega określonemu systemowi wartości wytworzonemu w danym środowisku, przy czym na wsi, gdzie wszyscy dobrze się znają, to wartościowanie jest wyrazistsze. W artykule zostanie zaprezentowane bogactwo nazw określających człowieka, który stale kłamie. Derywaty zanotowane w trakcie eksploracji terenowej pogranicza małopolsko-mazowieckiego są zróżnicowane zarówno leksykalnie (np.: brechacz, chełchun, cmanik, łgacz, kłamiec, picant, wywijas, zbereśnik), jak i słowotwórczo (np.: kłamca, kłamiec, kłamacz, kłamuśnik, kłamczuk, kłamus; łgun, łgarz, łgus). Celem artykułu jest pokazanie formalnych wykładników tworzących omawiane peiorativa oraz elementów znaczeniowych budujących ich wartość ekspresywną (pejoratywną), zawartych w podstawach słowotwórczych.

Jezus jako nauczyciel, mistrz. Apelatywne nazwy Syna Bożego w staropolskich i szesnastowiecznych przekładach Ewangelii
Authors: Kępińska Alina
Published: January 2025

Przedmiotem artykułu są różne występujące w staropolskich i szesnastowiecznych przekładach Ewangelii apelatywne nazwy Jezusa, podzielone na nazwy stosowane przez Niego samego oraz Jego uczniów. Są wśród nich takie, jak: mistrz, uczyciel, nauczyciel, przykażyciel, przystaw, rabbi czy rabbuni. To różne polskie ekwiwalenty takich greckich leksemów, jak didaskalos, epistates, w tym pożyczek hebrajskich w grece, jak rabbi i rabbuni. Stosowane są głównie jako formy adresatywne, w bezpośrednich zwrotach do osoby. Wyrazy te występują zarówno w tekście głównym, jak i w przypisach, zwłaszcza w tekstach protestanckich. Ich większa niż w grece i łacinie liczba wskazuje na twórczy namysł nad dokonywanym przekładem i doskonalenie warsztatu translatorskiego, a w translacjach innowierczych — ponadto na potrzebę odnowienia słownictwa kojarzonego z katolickim, na przykład uczyciel Szymona Budnego. W niewielkim zakresie leksyka z tej grupy potwierdza różnice konfesyjne.
Między konwencją a oryginalnością. O Pacierzu Ślęzakow do Pana Boga na Prusakow
Authors: Szagun Dorota
Published: January 2025

Artykuł dotyczy osiemnastowiecznego utworu zatytułowanego Pacierz Ślęzakow do Pana Boga na Prusakow. Podstawę analizy stanowi tekst napisany prawdopodobnie po 1742 roku, w czasie, gdy Śląsk przeszedł pod panowanie Prus. Utwór jest przykładem literatury popularnej i zaangażowanej społecznie. Względy pragmatyczne zadecydowały o powstaniu tekstu silnie skonwencjonalizowanego, odwołującego się do typowego gatunku modlitwy z jednej strony, z drugiej strony tekstu oryginalnego, posiadającego wyraźne odniesienia czasowe i społeczno-ideowe. Autorka wyraża przekonanie, że włączanie wzorca gatunkowego modlitwy Ojcze nasz do utworu poetyckiego wynika zarówno z powoływania się na autorytet i prestiż modlitwy, jak i z minimalizowania wysiłku w odbieraniu modlitewnego charakteru tekstu, wytwarzania poczucia wspólnoty etnicznej i religijnej poprzez odwołanie do tekstu rytualnego powszechnie znanego, a nawet silnie zinterioryzowanego, co w efekcie prowadzi do przekształcania zindywidualizowanej językowo wypowiedzi w głos zbiorowości.
O zbiorach tekstów do historii języka polskiego i ich nazwach
Authors: Migdał Jolanta , Walczak Bogdan
Published: January 2025

Artykuł zawiera przegląd zbiorów (antologii) tekstów do historii języka polskiego od połowy XIX wieku do dziś. Autorzy szczególny nacisk kładą na antologie w największym stopniu wyzyskiwane w dydaktyce uniwersyteckiej, to znaczy na antologie autorstwa Stefana Vrtela-Wierczyńskiego, Witolda Taszyckiego i spółki autorskiej Wiesława Wydry i Wojciecha Ryszarda Rzepki (o najnowszym, zbiorowym łódzko-zielonogórskim wyborze tekstów pod redakcją Marka Cybulskiego trudno coś stwierdzić w tym względzie, ponieważ dopiero się pojawił w księgarniach). Na tle dość schematycznych tytułów antologii (Wybór tekstów, Przegląd, Wyjątki, Zabytki, Teksty itd.) wyróżnia się Chrestomatia staropolska Wydry i Rzepki. Toteż autorzy kończą swoje opracowanie objaśnieniem wyrazu chrestomatia.
Publikacje naukowe oraz podręczniki szkolne Polski Ludowej w świetle recenzji cenzorskich z lat 50. XX wieku
Authors: Wiśniewska-Grabarczyk Anna
Published: January 2025

W artykule omawiam wybrane strategie cenzorskie wobec piśmiennictwa naukowego i oświatowego ocenianego przez urząd cenzury w latach 50. XX wieku: ewaluację cytowanej w dziele literatury, wyingerowanie informacji poufnych i kłopotliwych, rezygnację z oceny naukowej na rzecz realizacji ideologicznej publikacji. W świetle przedstawionych rozważań poufne recenzje cenzorskie stają się tylko jednym z ogniw procesu wydawniczego, a celem większości z nich jest jedynie ocena realizacji ideologicznej złożonej do Urzędu publikacji. Teksty naukowe niosły z sobą ryzyko ośmieszenia cenzora, odsłaniały „bariery kompetencyjne”, dlatego jeszcze wyraźniej niż w przypadku beletrystyki widać rzeczywiste cele cenzorskich ocen oraz pozorność tak zwanej oceny merytorycznej.
Zofia Rydet po latach
Authors: Czyżewski Stefan , Gołąb Mariusz
Published: January 2025

Monografia Zofia Rydet po latach. 1978–2018 to niewątpliwie publikacja naukowa najwyższej próby. Na jej wyjątkową wartość naukową nie tyle ma wpływ poprawność warsztatowa, jasność i logika wywodu, a nawet temat, który dotychczas nie doczekał się wyczerpującego omówienia w literaturze przedmiotu, co przede wszystkim prezentacja nowych, a ściśle rzecz ujmując, z tej okazji specjalnie pozyskanych źródeł, które niewątpliwie spełnią rolę materiału badawczego dla refleksji współczesnej humanistyki. Należy podkreślić, że owe źródła nie dotyczą wyłącznie samej Zofii Rydet, ale w niemałym stopniu odkrywają problematykę artystyczną i cechy kilku dekad twórczej działalności artystów fotomedialnego nurtu sztuki, co z natury rzeczy stanowi źródło wiedzy nie tylko o bohaterce opracowania, ale również kreśli panoramę polskiej fotografii i jej społecznych uwikłań w latach 1978–2018.

Łódź
Authors: Cieślak Tomasz
Published: January 2025

Książka to zbiór studiów prezentujących specyfikę łódzkiego doświadczenia nowoczesności na tle innych miast – centrów wytwórczych doby drugiej rewolucji przemysłowej w Europie. Publikacja analizuje reprezentację przestrzeni Łodzi w literaturze, począwszy od lat 80. XIX wieku po rok 1939, w utworach napisanych po polsku, w jidysz, po niemiecku i rosyjsku, co wynika z wielokulturowości miasta. Autor uwzględnia, w mniejszym stopniu, wybraną twórczość najnowszą. Korzysta zarówno z tekstów najwybitniejszych, jak i zapomnianych, sięga także po teksty publicystyczne i literaturę popularną. Głównym celem publikacji jest rekonstrukcja składowych „tekstu łódzkiego” (na wzór „tekstu petersburskiego” Władimira Toporowa). Rozwój „tekstu łódzkiego” wiąże się z przedstawionymi chronologicznie najistotniejszymi wydarzeniami z historii miasta: rewolucji 1905–1907, I wojny światowej, Wielkiego Kryzysu, ponieważ miały one decydujący wpływ na budowanie tożsamości lokalnej. Ukształtowany na przełomie XIX i XX wieku „tekst łódzki” okazuje się być, w świetle analiz, nadal obecny i produktywny dla kolejnych generacji twórców.
Evaluation of STE(A)M Education: An Analysis of Research and Practices from 2014 to 2023
Authors: Wong Billy T.M. , Cheong Li Kam , Liu Mengjin
Published: January 2025

STEM (Science, Technology, Engineering, and Mathematics) and STEAM (by including Arts) education (hereafter STE(A)M education) has been widely studied and practiced. Evaluation plays an important role in assessing and improving the effectiveness of relevant initiatives. Although there has been extensive research on evaluating STE(A)M education, little attention has been paid to examining the patterns of said evaluations. To address the research gap, this paper analyses relevant work on the evaluation of STE(A)M education practices with respect to their countries/regions, levels of education, discipline domains, pedagogical approaches, objectives of evaluation, evaluation areas, as well as data collection and analysis methods. It covers 339 publications from 2014 to 2023 which were collected from Scopus. Based on content analysis, the findings reveal a global interest in STE(A)M education and its evaluation, with a focus on secondary education and the core STEM subjects. The findings also highlight a diverse range of pedagogical approaches being used in STE(A)M education, with problem-based learning being the most popular. There has been a shift in evaluation objectives over the years, indicating a greater emphasis on determining the effectiveness of STE(A)M education and improving student learning performance. While academic achievement remained the most commonly evaluated area, there has been growing recognition of the importance of evaluating skills and competencies in STE(A)M education. The results also show a wide range of data sources and data analysis methods adopted for the evaluations.

Published: January 2025

This study aims to analyze the influence of social media on improving disaster preparedness and response among STIKES Muhammadiyah Aceh students. The approach used is quantitative with the cross-sectional method, where research is carried out at a specific point in time. Informants were selected using random sampling, and data were collected through a Guttman scale questionnaire that offered "Yes" or "No" answer choices. This method is expected to yield clear responses to the issues studied. Data analysis was conducted through stages of coding, cleaning, transferring data to a computer, presenting, and analyzing. The study results reveal that social media plays a significant role in disaster education among students. Five main indicators were identified: disaster knowledge and attitudes (98% of students acknowledge that social media increases their knowledge about disasters), information dissemination (98% recognize social media as the fastest source of information), early warning systems (52% feel the current system is inadequate), student participation (73% are willing to engage in open donations or disaster training), and social capital (62% obtain information through disaster-related social media groups or platforms).In conclusion, social media is a vital tool for enhancing disaster preparedness and accelerating information dissemination among students. However, improvements are still needed in early warning systems and the overall effectiveness of social media in disaster response.
Evaluating the Impact of an Educational Intervention on Nursing Labor Support Practices and Cesarean Birth Rates
Authors: Jeanmougin Caitlin
Published: January 2025

Background:Over 30% of births in the United States occur via cesarean section despite increased risks to the birthing person and neonate. Evidence-based nursing practice related to fetal monitoring, patient positioning, and management of the second stage of labor can decrease the incidence of cesarean birth.Objective:The objective is to decrease the cesarean birth rate by 3% in a Midwestern suburban hospital.Methods:Baseline data on demographics, labor interventions, and birth outcomes were collected for 4 weeks (n= 85 births). The intervention included a sample of 24 labor nurses who took a pretest, viewed a narrated PowerPoint on methods to promote vaginal birth, and completed a posttest. Data were then collected for another four weeks (n= 90 births).Results:The mean improvement in posttest scores was 4.792 points, providing strong evidence that this education would result in a score increase between 3.9 and 5.6 with 95% confidence. There was no increase in the number of nursing interventions utilized during labor. The overall cesarean birth rate increased from 18.8% to 28.9%.Conclusions:The education was highly effective in increasing nurse knowledge, but this did not affect a change in nursing practice or cesarean birth rate.Implications for Nursing:High-quality education is not enough to change practice or outcomes. Additional research is needed on barriers that prevent the translation of knowledge into practice.

Contribution à l'élaboration d'un modèle du commerce international des grumes de bois tropicaux
Authors: Schirmer Isabelle , Buongiorno Joseph
Published: January 2025

Des modèles de commerce de grumes tropicales sont présentés pour deux régions : Afrique Europe et Asie-Pacifique.Chaque modèle utilise les équations économétriques de l'offre et de la demande pour chaque sous-région et chaque pays. Il calcule ensuite l'équilibre spatial à l'aide de la programmation quadratique, en maximisant le surplus du producteur et du consommateur. La solution primaire quantifie la demande, l'offre et les échanges. La solution duale donne les prix d'équilibre.Le modèle pour l'Afrique et l'Europe est une modification de celui d'Adams (Modélisation du commerce mondial des bois tropicaux, FAO, 1983). Ici, le marché des sciages précède le marché des grumes et les équilibres sur les deux marchés sont calculés de manière itérative. Les résultats pour l'année 1980 étaient similaires en précision à ceux d'Adams.Le modèle pour l'Asie-Pacifique ne concerne que les grumes. Les prévisions test pour 1979 et 1980 ont donné des résultats satisfaisants, mais pas celles de 1981 après que l'Indonésie a diminué ses exportations de grumes.
Pisciculture du Pirarucu
Authors: Bard Jacques , Palmeira Imbirida Emir
Published: January 2025

Le pirarucu, Arapaima gigas, famille des Ostéoglossidés, est le plus grand poisson d'eau douce du monde. C'est un poisson d'eau chaude équatoriale qui vit dans le bassin du fleuve Amazone. Son régime alimentaire est carnivore et il respire l'air à la surface. Son habitat naturel est l'eau « noire » des forêts, dans les endroits calmes. La reproduction a lieu pendant la saison des pluies. Il est pêché principalement au harpon.La reproduction en eaux artificielles est facile, mais la séparation des sexes est difficile et la grande taille des reproducteurs est une complication (ils pèsent plus de 40 kg). Le pirarucu a été utilisé avec succès dans la pisciculture extensive dans les réservoirs du nord-est du Brésil. En pisciculture intensive, il est facilement élevé dans des étangs de toutes tailles. Les rendements obtenus à l'heure actuelle varient de 1,7 à 11 tonnes/hectare/an, mais une meilleure production pourrait être obtenue. Les alevins sont récoltés au moyen de filets coulés dans les eaux naturelles ou les réservoirs, ceci afin d'économiser l'entretien de l'éleveur. L'alimentation se fait soit à l'aide de petits poissons locaux, soit à l'aide de petits Tilapia produits à partir de fertilisation organique provenant de bovins ou de buffles en élevage associé ou de tout autre procédé bon marché. Le poids moyen (individuel) en pisciculture intensive est compris entre 5 et 10 kg, voire plus, et la chair fraîche du pirarucu a le même goût que celle de la morue fraîche.

Published: January 2025

Titanium carbide (TiC) and tungsten carbide (WC) are essential engineering materials known for their exceptional hardness, wear resistance, and thermal stability. This study investigates the formation, phase stability, mechanical properties, and electronic structure of (Ti,W)C solid solutions. The research employs computational methods, including Density Functional Theory (DFT) and Cluster Expansion (CE), to explore compositional variations and their effects. Results reveal that Ti0.5W0.5C demonstrates superior thermodynamic stability, while intermediate compositions such as Ti0.67W0.33C achieve peak hardness (~33 GPa) due to the synergistic effects of covalent Ti-C and metallic W-C bonding. The electronic structure analysis highlights hybridized bonding characteristics that optimize mechanical resilience and thermal stability. Elastic and vibrational properties show a notable influence of tungsten incorporation, enhancing bulk modulus and enabling tailored properties. These findings provide critical insights for the development of high-performance materials in applications such as machining, wear-resistant coatings, and structural components.
A Smoothed Filtering and Correction Factor Proposal for ERT2D and TDIPT2D Data Collected in Difficult Terrain to Improve Inversion Models
Authors: Tejero-Andrade Andrés , López-González Aide E. , Tejero-Andrade José M. , Chávez-Segura René E. , Espino Denise L. Argote
Published: January 2025

When collecting data from ERT2D (electrical resistivity tomography) and TDIPT2D (time domain IP tomography), different phenomena occur, whether natural or anthropogenic noise, which contaminate the data, and it can make their processing, analysis and interpretation difficult. Different techniques have been developed to eliminate or reduce these effects on the data, such as noise filtering or the development of new techniques for better data collection in the field. In the present work an iterative weighted least squares filter is employed after voltage normalization by current and a geometrical factor correction applied on strong topographic terrains. The selection of the filter basis function is recommended to be able to represent the natural behavior of the function to be filtered. Stationary or variable voltages in electrical prospecting decay with the inverse of the distance, which can be represented by an expansion in Legendre polynomials. On the other hand, uneven spacing of the electrodes leads to not using the correct geometric factor which results in an error in the calculation of the electrical anomaly. The efficiency of the proposed technique is analyzed and tested with field examples using different filters and applying the proposed correction factor or without using it. The results indicate a low RMS and L2-Norm error, whereby a better definition of the inverted resistivity image is obtained. For the TDIP case a better correspondence between the inverted images of resistivity and chargeability can be reached.
Analysis of Seismic Site Effects in Plio-Quaternary Intermontane Basin (L'Aquila, Central Italy)
Authors: Tallini Marco , Morana Enrico , Guerriero Vincenzo
Published: January 2025

This study presents a comprehensive analysis of site effects in the highly seismic area of L'Aquila in central Italy, which has been conducted within the framework of a seismic microzonation project funded by the Abruzzo Region's Department of Government of the Territory and Environmental Policies. The project was aimed at best practice on the management of urban and land territory for seismic risk mitigation. Through the integration of detailed geophysical and geotechnical data with numerical modeling, we provide an accurate assessment of local seismic amplification. Two-dimensional numerical simulations using the LSR 2D code were performed on many representative geological sections to compute amplification factors for various period ranges. This case study allowed us to outline some key considerations for best practices in local seismic response analysis and seismic microzonation studies in Italy. Given the prevalence of 2D basin edge, buried morphology and topographic effects in Plio-Quaternary geologically complex intermontane basins in central Italy, as demonstrated in the LAB case study, use of two-dimensional models is suggested. In order to validate the numerical models and their associated spectra and AFs, is also suggested to compare transfer functions with HVSR microtremor measurements at control points along the studied sections.

Published: January 2025

The poultry industry plays a pivotal role in global agriculture, serving as a major source of protein and contributing significantly to economic growth. However, the sector faces challenges associated with labor-intensive tasks that are repetitive and physically demanding. Automation has emerged as a critical solution to enhance operational efficiency and improve working conditions. Specifically, robot manipulation and handling of objects is becoming ubiquitous in factories. However, challenges exist to precisely identify and guide the robot to handle a pile of objects with similar textures and colors. This paper focuses on the development of a vision system for a robotic solution aimed at automating the chicken rehanging process, a fundamental yet physically strenuous activity in poultry processing. To address the limitation of the generic instance segmentation model in identifying overlapped objects, a cost-effective dual-active laser scanning system was developed to generate precise depth data of objects. The generated well-registered depth data integrated with the RGB images were sent into the instance segmentation model for individual chicken detection and identification. This enhanced approach significantly improved the model’s performance in handling complex scenarios involving overlapping chickens. Specifically, the integration of RGB-D data increased the model’s mean Average Precision (mAP) detection accuracy by 4.9% and significantly improved the center offset—a customized metric introduced in this study to quantify the distance between the ground truth mask center and the predicted mask center. Precise center detection is crucial for the development of future robotic control solutions, as it ensures accurate grasping during the chicken rehanging process. The center offset was reduced from 22.09 pixels (7.30 mm) to 8.09 pixels (2.65 mm), demonstrating the approach’s effectiveness in mitigating occlusion challenges and enhancing the reliability of the vision system.

Vulvovaginal atrophy (VVA) is one of the most common side effects of chemoradiation therapy, including an associated decrease in quality of life, particularly sexual function. The gold-standard treatment for VVA, a local estrogen therapy, is contraindicated in patients who have undergone anti-tumor therapy due to potential cancer risks. Today, there is no evidence base for the direct oncogenic effect of high-molecular-weight hyaluronic acid (HMW-HA) on malignant tumors of various localizations. Moreover, several researchers have demonstrated its cancer neutrality or even protective properties. Therefore, well-designed and high-quality studies are needed to evaluate not only the efficacy but also the long-term safety of HA use in
patients with a history of cancer.

Objective. To determine the outcomes in newborns with early- and late-onset fetal growth restriction (FGR) using a comparative analysis and considering different clinical approaches to the diagnosis of this condition.
Materials and methods. A retrospective analysis of outcomes was performed in 394 newborns with a verified diagnosis of FGR born between 2018 and 2022 in the Perinatal Center of the Arkhangelsk Regional Clinical Hospital. Birth and neonatal histories were obtained by continuous sampling. Considering the transition to new criteria for the diagnosis of FGR and depending on different clinical approaches to the diagnosis of FGR, four study groups were identified.
Results. The highest neonatal morbidity rate was observed in the groups with early-onset FGR according to the Delphi consensus criteria, the most significant among them were infectious diseases (OR: 3.1; 95% CI: 1.02–9.5), intraventricular hemorrhage (OR: 11.9; 95% CI: 4.02–35.5), severe asphyxia (OR: 3.5; 95% CI: 1.3–9.1), multiple organ failure (OR: 7.4; 95% CI: 2.6-20.9), and retinopathy (OR: 4.8; 95% CI: 1.3–17.8). Also, this subgroup had higher rates of intrapartum mortality (OR: 3.56; 95% CI: 0.78–16.1) and early neonatal mortality (OR: 3.0; 95% CI: 0.47–19.2).
Conclusion. Neonatal outcomes were in direct correlation with gestational age and FGR severity. It is worth emphasizing the subgroup of infants born before 32 weeks’ gestation, which does not meet the current criteria for FGR. Their outcomes by most parameters correspond to fetuses with a gestational age of more than 34 weeks and without signs of FGR, which confirms the relevance of the Delphi criteria and makes such cases a reserve group for reducing the total number of preterm births.

Objective. To determine the prognostic criteria for preterm birth due to SARS-CoV-2 infection.
Patients and methods. A retrospective case-control study was conducted. Data on 1041 pregnant women infected with COVID-19 in the third trimester between April 2020 and December 2022 were analyzed. The Chi-square test was used to compare qualitative variables. The binary logistic regression model was used to identify factors associated with preterm birth in women infected with COVID-19. The ROC curve analysis for logistic regression was performed to assess the prognostic significance of the combination of the identified risk factors for preterm birth in women with COVID-19.
Results. Regression analysis showed a positive correlation between pre-eclampsia (OR = 2.927, 95% CI: 1.328–6.452, p = 0.008), chronic infections (OR = 3.751, 95% CI: 1.931–7.287, p < 0. 0001), absence of therapy with low-molecular-weight heparin (OR = 2.481, 95% CI: 1.302–4.729, p = 0.006) and acetylsalicylic acid (OR = 1.945, 95% CI: 1.051–3.597, p = 0.034) and preterm birth. The ROC curve analysis for separate factors such as the absence of therapy with low-molecular-weight heparin and acetylsalicylic acid, age, aggravated obstetric history, pre-eclampsia and chronic infections did not show a high predictive value. The area under the curve (AUC) was less than 0.6 (0.395; 0.445; 0.589; 0.557; 0.558; 0.575, respectively). At the same time, the combination of absent anticoagulant therapy and each factor separately had a significantly higher prognostic value (AUC above 0.6 in all cases).
Conclusion. The risk of preterm birth in pre-eclampsia and the presence of chronic infections in pregnant women infected with COVID-19 in the third trimester is significantly higher in the absence of anticoagulant therapy.

Critical spin chains and loop models with $PSU(n)$ symmetry
Authors: Roux Paul , Jacobsen Jesper Lykke , Ribault Sylvain , Saleur Hubert
Published: January 2025

Starting with the Ising model, statistical models with global symmetries provide fruitful approaches to interesting physical systems, for example percolation or polymers. These include the O(n)O(n) model (symmetry group O(n)O(n)) and the Potts model (symmetry group S_QSQ). Both models make sense for n,Q∈ \mathbb{C}n,Q∈ℂ and not just n,Q∈ \mathbb{N}n,Q∈ℕ, and both give rise to a conformal field theory in the critical limit. Here, we study similar models based on the group PSU(n)PSU(n). We focus on the two-dimensional case, where the models can be described either as gases of non-intersecting orientable loops, or as alternating spin chains. This allows us to determine their spectra either by computing a twisted torus partition function, or by studying representations of the walled Brauer algebra. In the critical limit, our models give rise to a CFT that exists for any n∈\mathbb{C}n∈ℂ and has a global PSU(n)PSU(n) symmetry. Its spectrum is similar to those of the O(n)O(n) and Potts CFTs, but a bit simpler. We conjecture that the O(n)O(n) CFT is a \mathbb{Z}_2ℤ2 orbifold of the PSU(n)PSU(n) CFT, where \mathbb{Z}_2ℤ2 acts as complex conjugation.
Site-wise dynamic defects in a non-conserving exclusion process
Authors: Bhatia Nikhil , Gupta Arvind Kumar
Published: January 2025

Motivated by the significant influence of the defects in the dynamics of the natural or man-made transportation systems, we propose an open, dynamically disordered, totally asymmetric simple exclusion process featuring bulk particle attachment and detachment. The site-wise dynamic defects might randomly emerge or vanish at any lattice location, and their presence slows down the motion of the particles. Using a mean-field approach, we obtain an analytical expression for both particle and defect density and validate them using Monte Carlo simulation. The study investigates the steady-state characteristics of the system, including phase transitions, analysis of boundary layers, and phase diagrams. Our approach streamlines the defect dynamics by integrating two parameters into one called the obstruction factor, which helps in determining an effective binding constant. The impact of the obstruction factor on the phase diagram is explored across various combinations of binding constants and detachment rates. A critical value of the obstruction factor is obtained, about which an infinitesimal change results in a substantial qualitative change in the structure of the phase diagrams. Further, the effect of the detachment rate is studied, and critical values along which the system observes a quantitative transition of the stationary phases are obtained as a function of the obstruction factor. Overall, the system shows stationary phases ranging from three to seven depending upon the value of the obstruction factor, the binding constant, and the detachment rate. Moreover, we scrutinized the impact of the obstruction factor on the shock dynamics and found no finite-size effect.
