ISG15, an IFN-stimulated gene, plays a crucial role in modulating immune responses during viral infections. Its upregulation is part of the host’s defense mechanism against viruses, contributing to the antiviral state of cells. However, altered ISG15 expression can also lead to immune dysregulation and pathological outcomes, particularly during persistent viral infections. Understanding the balance of ISG15 in promoting antiviral immunity while avoiding immune-mediated pathology is essential for developing targeted therapeutic interventions against viral diseases. In this article, using Usp18-deficient, USP18 enzymatic-inactive and Isg15-deficient mouse models, we report that a lack of USP18 enzymatic function during persistent viral infection leads to severe immune pathology characterized by hematological disruptions described by reductions in platelets, total WBCs, and lymphocyte counts; pulmonary cytokine amplification; lung vascular leakage; and death. The lack of Usp18 in myeloid cells mimicked the pathological manifestations observed in Usp18−/− mice and required Isg15. Mechanistically, interrupting the enzymes that conjugate/deconjugate ISG15, using Uba7−/− or Usp18C61A mice, respectively, led to accumulation of ISG15 that was accompanied by inflammatory neutrophil accumulation, lung pathology, and death similar to that observed in Usp18-deficient mice. Moreover, myeloid cell depletion reversed pathological manifestations, morbidity, and mortality in Usp18C61A mice. Our results suggest that dysregulated ISG15 production and signaling during persistent lymphocytic choriomeningitis virus infection can produce lethal immune pathology and could serve as a therapeutic target during severe viral infections with pulmonary pathological manifestations.

Published: November 2024

INTRODUCTION: Cervical cancer is the most common malignant tumor in the female reproductive system, with the number of deaths due to cervical cancer in developing countries accounting for 80% of the global total. In China, the incidence rate of cervical cancer is increasing year by year. At present, the commonly used methods for cervical cancer screening include TCT, HPV testing, TCT+HPV combined testing, FRD, and VIA/VILI. Among them, although TCT+HPV combined testing has high sensitivity and specificity, it is costly and time-consuming. VIA/VILI screening is cost-effective, easy to operate, and suitable for promotion in economically underdeveloped areas.However, VIA/VILI screening relies on the subjective judgment of doctors, so its accuracy is relatively low in rural areas of China with a large population and a lack of well-trained doctors. To address this issue, computer-aided diagnosis (CAD) technology is needed to improve the accuracy and reliability of VIA/VILI screening.
OBJECTIVES: The implementation of artificial intelligence (AI)-based Visual Inspection with Acetic acid (VIA) screening and computer-aided diagnosis has the potential to significantly reduce the cost of cervical cancer screenings and increase the coverage rate of cervical cancer screenings, thus reducing the incidence rate of the disease. To this end, we have developed an AI preprocessing algorithm aimed at improving the accuracy of AI in detecting cervical cancer.
METHODS: Initially, the algorithm maps images to the YCrCb and Lab color spaces. Unlike traditional enhancement methods that mainly focus on the luminance channel, our method primarily enhances the Cr channel in the YCrCb color space and a channel in the Lab color space. This paper innovatively proposes the LT_CLAHE algorithm to enhance the Cr channel, obtaining an enhanced image with a bias towards blue-green colors, and uses the WLS algorithm to enhance the a channel, obtaining an enhanced image with a bias towards red colors. Subsequently, the enhanced images from both color spaces are fused to eliminate color distortion.
RESULTS: Experimental results show that our method significantly enhances the texture of lesions and outperforms traditional methods across various objective indicators. When the enhanced images from this paper are used as input for neural networks, there is also a significant increase in the accuracy of neural network detection.
On the speed of convergence in the ergodic theorem for shift operators
Authors: Chalmoukis Nikolaos , Colzani Leonardo , Gariboldi Bianca , Monguzzi Alessandro
Published: November 2024

Given a probability space

$(X,\mu )$

, a square integrable function f on such space and a (unilateral or bilateral) shift operator T, we prove under suitable assumptions that the ergodic means

$N^{-1}\sum _{n=0}^{N-1} T^nf$

converge pointwise almost everywhere to zero with a speed of convergence which, up to a small logarithmic transgression, is essentially of the order of

$N^{-1/2}$

. We also provide a few applications of our results, especially in the case of shifts associated with toral endomorphisms.
$\mathrm{C}^{*}$
-algebras hereditarily containing nonzero, square-zero elements

Published: November 2024

We introduce and study the weak Glimm property for
$\mathrm{C}^{*}$
-algebras, and also a property we shall call (HS
$_0$
). We show that the properties of being nowhere scattered and residual (HS
$_0$
) are equivalent for any
$\mathrm{C}^{*}$
-algebra. Also, for a
$\mathrm{C}^{*}$
-algebra with the weak Glimm property, the properties of being purely infinite and weakly purely infinite are equivalent. It follows that for a
$\mathrm{C}^{*}$
-algebra with the weak Glimm property such that the absolute value of every nonzero, square-zero, element is properly infinite, the properties of being (weakly, locally) purely infinite, nowhere scattered, residual (HS
$_0$
), residual (HS
$_{\text {t}}$
), and residual (HI) are all equivalent, and are equivalent to the global Glimm property. This gives a partial affirmative answer to the global Glimm problem, as well as certain open questions raised by Kirchberg and Rørdam.

Published: November 2024

Türk Evi idealinin akademik söylemde ele alınması, mimarlık alanında önemli bir tartışma konusu olarak öne çıkmaktadır. Değişen şartlara rağmen, düşük yoğunluklu olsa da Türk Evi kavramı araştırma konusu olmaya devam etmiş, morfoloji, tipoloji ve yapı teknolojileri gibi mimari çalışmaların bir parçası olmuştur. 1970'lerden itibaren artan eleştirilere rağmen, bu kavram kurumsallaşmış ve Osmanlı veya Anadolu konut kültürünü bu kavramın paradigmaları içinde tartışmak kaçınılmaz hale gelmiştir. Bu makalede, ideal "Türk Evi"ne yüklenen anlamların ve dünya ölçeğinde insanlığı bekleyen ekolojik ve sosyokültürel krizlere karşı "Türk Evi" modelinin inşa edilebilirlik, sürdürülebilirlik, enerji verimliliği ve kullanıcı odaklı tasarım açısından çözümün bir parçası olabileceği “Akın Evi” örneği üzerinden anlatılmaktadır. Araştırma unutulmaya yüz tutmuş olan "Türk Evi" kavramını yeniden canlandırarak, geleneksel inşa tekniklerinin basit, kolay, sade ve mevzuata uygun olduğunu, geleneksel inşa tekniklerini kullanarak insanlara kendi evlerini yapabileceklerini göstermektedir. Ayrıca, geleneksel “Türk Evinin” adaptif yeniden kullanım potansiyeli ve bağlamsal duyarlılığı, modern mimarlık pratiklerinde dikkate alınması gereken önemli unsurlar olarak öne çıkmaktadır. Bu bağlamda Türk evleri ve sürdürülebilirlik konusunda daha fazla araştırma yapılması ve literatürün genişletilmesi, geleneksel mimarinin sürdürülebilirlik potansiyelini daha iyi anlamamıza ve çevre dostu yapı tasarımları için ilham kaynağı sağlamamıza yardımcı olabilir.

Nonmonotone Spectral Analysis for Variational Inclusions
Authors: Hazaimah Oday
Published: November 2024

Gradient descent algorithms perform well in convex optimization but can get tied for finding local minima in non-convex optimization. A robust method that combines a spectral approach with nonmonotone line search strategy for solving variational inclusion problems is proposed. Spectral properties using eigenvalues information are used for accelerating the convergence. Nonmonotonic behaviour is exhibited to relax descent property and escape local minima. Nonmonotone spectral conditions leverage adaptive search directions and global convergence for the proposed spectral subgradient algorithm.

Small bowel diverticulosis is a rare condition, with an incidence ranging between 0.3% and 1.3% in the general population. Although it is typically asymptomatic, it can lead to severe complications such as perforation, diverticulitis, bleeding, and intestinal obstruction. These cases require rapid and accurate diagnostic evaluation, with computed tomography and ultrasound being essential due to the lack of established diagnostic protocols. We present the case of a 61-year-old woman with a history of colonic diverticulosis, who developed abdominal pain, fever, melena, and septic shock. Imaging revealed an intestinal perforation, confirmed by exploratory laparotomy, which identified jejunal diverticulosis with perforation. A resection of 90 cm of the small intestine was performed with a primary anastomosis. The patient recovered well in the intensive care unit. This case highlights the importance of early diagnosis and surgical intervention in small bowel diverticulosis complications, a condition that, though uncommon, can be potentially serious.

This research aims to find out the form and meaning of Javanese women’s resistance of NyiMisni, a Javanese woman character in the film entitled “Perempuan Tanah Jahanam” (2019), and how her masculinity is reflected through the interaction between her and other characters in the film. The analysis is conducted in the context of patriarchal domination over Javanese women specifically, and Indonesian women in general. The main data is obtained from the dialog uttered by the main female character, NyiMisni, in Joko Anwar’s “Perempuan Tanah Jahanam” (2019) film. It is supported by secondary data from other articles that mentioned masculinity traits shown by Javanese female characters in other films. The method of collecting data used in this research is the observation method using an observation technique. The techniques conducted are watching the movie, note-taking all dialogues that contain masculinity features, and classifying the data based on the masculinity features shown by NyiMisni. The analysis is conducted using Bem’s Sex Role Inventory (1982) and the theory of symbolic interactionism by Smelser (2013. Furthermore, the speech act theory by Searle (1976) is used as the supporting theory. The findings discovered some forms and meanings of Javanese women’s resistance as the masculinity features shown by NyiMisni and how she interacts with other participants through her utterances. Female masculinity is featured in assertiveness, dominance, and aggression. Her utterance is directly conducted, yet the intention is indirect.

Developing abstract and generalizing thinking is an important skill that helps people approach problems more comprehensively, creatively, and effectively in study, work, and life. In the modern world, we often face large and complex amounts of information. The ability to abstract helps us filter out unnecessary details, focusing only on important factors. Generalization helps us simplify information, making them easier to understand and manage. Grade 4 Math has a lot of potential to develop abstract and generalizing thinking for students.This article proposes some measures to train students' abstract and generalizing thinking in teaching the topic of fraction operations in grade 4. These are also some suggestions for managers and teachers of primary schools in Vietnam to improve the quality of teaching Mathematics in general.

Published: November 2024

Twenty bacterial strains had been isolated from root nodules of Genista saharae that grew wild in Biskra and El Oued city (Northeastern Algerian Sahara). This study focused on obtaining isolates of legume nodule bacteria (LNB) from the plant G. saharae and evaluated their effectiveness in forming a symbiotic relationship with the legume species Vigna unguiculata through cross-inoculation. Additionally, the study aimed to identify the successful cross-inoculation group of LNB strains based on their phenotypic characteristics. The growth capacity of isolates under varying salinity conditions [NaCl] and pH levels was investigated using a spectrophotometer (96-microplate reader). The API 20NE and API 20E systems were used to identify the biochemical characteristics of the isolates. In addition, the rhizospheric soil samples from the two study sites were analyzed using standard analytical techniques of soil. All isolates established effective symbioses with Vigna unguiculata, were Gram-negative rods, and were fast-growing. The optimal growth temperature was between 28 °C and 37 °C; some isolates were thermophiles and specifically withstood extreme heat between 45-50 °C. Furthermore, they demonstrated a wide tolerance range to pH (5–10) with salt tolerance ranging from 100 mM to 500 mM. Biochemical results revealed that the isolates assimilated various sources of carbon and nitrogen and displayed numerous enzyme activities. Physicochemical analysis revealed that all the soils were deficient in nutrients and had an alkaline pH. This study enabled us to identify the effective stress-tolerant strains, which could be used in the future to inoculate plants for environmental applications.

Authors:   , Barbosa Lucas Ladeira
Published: November 2024

Os processos morfogênicos glaciais que atuaram na Cordilheira Fueguina ao longo do período holocênico, em um substrato geológico predominantemente metamórfico de controle tectônico estrutural, exerceram na paisagem um marcante um controle estrutural. Pretendeu-se com o primeiro capítulo identificar, delimitar e caracterizar os geoambientes da Cordilheira Fueguina a partir da estratificação ambiental, agrupando ecossistemas terrestres com características similares em relação aos seus atributos pedo-lito-fito-geomorfológicos. A partir da seleção de um conjunto de variáveis preditoras, a distribuição dos cinco geoambientes identificados na paisagem foi mapeada por modelos de aprendizado de máquinas. Um gradiente ambiental se desenvolve na topossequência, em que se observa íntima relação entre a ocorrência de solos em diferentes segmentos da paisagem sendo fortemente influenciados pela altitude, clima, relevo e vegetação. O segundo capítulo teve como objetivo estudar as propriedades químicas, físicas, mieralógicas e orgânicos dos solos ao longo de uma topossequência típica da Cordilheira Fueguina. As principais variações edáficas presentes na área de estudo foram representadas a partir da amostragem de dez perfis de solo típicos, ao longo de um gradiente de altitude. Os solos foram descritos em campo, classificados pelo sistema WRB/FAO e tiveram seus principais atributos analisados e discutidos neste estudo. Os principais processos pedogenéticos identificados na região foram a podzolização, paludização e crioclastia, e foram divididos em solos minerais e orgânicos com base em seus componentes majoritários para melhor sistematização dos resultados. De modo geral, com a diminuição da altitude os solos se tornam mais profundos, com estrutura mais desenvolvida e com incremento dos teores de silte e argila em detrimento da fração areia, e aumentam-se os estoques de carbono orgânico no solo. Os dois capítulos deste trabalho abordam aspectos fundamentais do meio físico e biótico da Cordilheira Fueguina. Palavras-chave: pedodiversidade, modelagem ambiental; pedogênese

The three pillars regulating international sales contracts on the African continent
Authors: Wethmar-Lemmer Marlene M
Published: November 2024

In 2018 is die Afrika Vastelandse Vryehandelsooreenkoms (African Continental Free Trade Agreement) gesluit met die bedoeling om ’n gemeenskaplike mark vir goedere en dienste op die kontinent te vestig ten einde ekonomiese integrasie en beleggingsgeleenthede te bevorder met die vermindering van armoede as einddoel. Die uiteenlopende regstelsels in Afrika vergestalt die grootste nie-tarief struikelblok vir internasionale handel op die kontinent. Die harmonisering van die regsbeginsels, veral insake alle aspekte rakende internasionale koopkontrakte is dus van kardinale belang vir die bevordering van handel tussen Afrikalande maar ook tussen Afrikalande en hul handelsvennote wêreldwyd. Daar bestaan afdoende bewyse dat internasionale kommersiële arbitrasie die verkose dispuutbeslegtingsmeganisme in internasionale handelsdispute daarstel. Die harmonisering van die substantiewe regsreëls wat internasionale koopkontrakte en verbandhoudende transaksies reguleer; die harmonisering van die aanwysingsreëls oftewel die reëls van die internasionale privaatreg wat die toepaslike substantiewe regsreëls aandui asook die harmonisering van die prosedurele reëls wat internasionale arbitrasie beheers, verteenwoordig dus die drie pilare vir die effektiewe regulering van internasionale handel in Afrika. In hierdie bydrae word dié drie elemente ontleed en voorstelle aan die hand gedoen om kontinentale harmonisering van aldrie te bewerkstellig. Eerstens word aanbeveel dat alle state in Afrika lidlande van die Weense Koopverdrag van 1980 (CISG) word. Tans het die Weense Koopverdrag sewe-en-negentig lidlande wêreldwyd, verteenwoordigend van alle regstradisies. Ten spyte van die feit dat hierdie verdrag meer as veertig jaar oud is, groei die aantal lidlande steeds – meer as twintig lande het sedert 2010 tot die Weense Koopverdrag toegetree. Hierdie standhoudende groei in die getal lidlande dui daarop dat die CISG steeds as ’n gesaghebbende en geldige stel substantiewe internasionale koopreëls beskou word. Tweedens, wat die harmonisering van die aanwysingsreëls betref, word aan die hand gedoen dat die African Principles on the Law Applicable to International Commercial Contracts die beste grondslag daarstel vir harmonisering van tans uiteenlopende benaderings in Afrika tot die vasstel van die toepaslike reg. Derdens word daar na die Wet op Internasionale Arbitrasie 15 van 2017 en die skedules tot daardie wet gekyk vir die harmonisering van die prosedurele regulering van internasionale kommersiële arbitrasie.
A brief overview of collective consumer redress in the European Union and South Africa and moving towards the increased use of a consumer class action in South Africa – part two
Authors: Broodryk Theo
Published: November 2024

Building upon the groundwork laid in part one of this two-part article, which illuminated the landscape of collective consumer redress within the European Union (EU), part two delves into the unique trajectory of this legal phenomenon in South Africa. While collective consumer redress is still a burgeoning concept in these jurisdictions, the dynamics governing it display distinctive characteristics, especially in a consumer context. This article commenced by considering the position in South Africa, where class actions under section 4(1) of the Consumer Protection Act 68 of 2008 are specifically scrutinised. Surprisingly, there is a paucity of such actions, prompting a closer examination of the reasons for this. The article seeks to elucidate the status of collective consumer redress in South Africa and to uncover potential insights from the European Union. By scrutinising these frameworks, the article aims to assess whether South Africa could derive benefits from adapting certain elements to enhance the efficacy of its own consumer class actions under the act. Ultimately, the overarching goal of this two-part article is to identify strategies that optimise consumer class action, paving the way for enhanced access to justice for South African consumers. As we navigate through the legal landscape of South Africa, our pursuit is guided by the quest for a more robust and equitable collective redress system that aligns with the evolving needs of consumers in these jurisdictions.
Aantekeninge: A renewed call for a wider recognition of the pactum successorium in light of recent developments
Authors: Kloppers Henk , Gildenhuys Anel
Published: November 2024

Behoudens ’n vererwingsklousule in ’n geregistreerde huweliksvoorwaardekontrak en ’n donatio mortis causa wat aan testamentêre formaliteite voldoen, word alle ander vorme van erfopvolgingsooreenkomste (pacta successoria of pactum successorium as die enkelvoud) as onafdwingbaar beskou. Die vernaamste hedendaagse besware teen die erkenning van die pactum successorium is die beperking van testeervryheid waar die individu van die geleentheid om vererwing deur ’n testament te bewerkstellig ontneem word en die moontlike omseiling van testamentêre formaliteite soos voorgeskryf in artikel 2 van die Wet op Testamente 7 van 1953. Alhoewel verskeie outeurs oor die jare heen (veral in die 1980’s en 1990’s) vir ’n verslapping van die streng verbod op die erkenning van die pactum successorium betoog het, blyk dit dat die howe nie ten gunste van sodanige verslapping is nie. Die pactum successorium was die onderwerp van twee onlangse uitsprake (Oosthuizen v Barnard (20665/2021) 2023 ZAGPPHC 30 (24 Jan 2023) en Lotter v Trustees for Time Being of Phildi Trust (13754/2023) 2024 ZAWCHC 158 (7 Junie 2024)) in die konteks van skikkingsooreenkomste wat in egskeidingsbevele geïnkorporeer is. In beide sake het die howe die vestigingstoets (soos geformuleer in Jubelius v Griesel NO 1988 2 SA 610 (K) en goedgekeur in McAlpine v McAlpine 1997 1 SA 736 (HHA)) toegepas en tot die gevolgtrekking gekom dat die onderskeie erfopvolgingsklousules in die skikkingsooreenkomste inderdaad pacta successoria daarstel, en aangesien dit nie binne die erkende uitsonderings val nie, is die klousules by verstek onafdwingbaar. As kritiek teen die kunsmatige benadering wat deur die howe gevolg word, probeer die outeurs van hierdie bydrae voortbou op die vorige oproepe vir die wyer erkenning van die pactum successorium in die lig van algemene ontwikkelinge wat sedert die 1980’s en 1990’s plaasgevind het, spesifiek met verwysing na die moontlike insluiting van ’n derde erkende vorm van die pactum successorium naamlik ’n erfopvolgingsklousule in ’n egskeidingskikkingsooreenkoms, welke ooreenkoms ’n bevel van die hof gemaak is. Formaliteite, statutêre beperkings en onlangse uitsprake wat testeervryheid beperk, sal uiteengesit word om die huidige primêre besware teen die pactum successorium (soos genoem ’n beperking op testeervryheid en die omseiling van testamentêre formaliteite), te betwis. Met verwysing na die uitsprake in die Oosthuizen- en Lotter-sake kom die outeurs tot die gevolgtrekking dat, gegewe die formaliteite verbonde aan die insluiting van ’n skikkingsooreenkoms in ’n egskeidingsbevel, sodanige ooreenkomste as ’n derde uitsondering op die streng verbod teen die erkenning van die pactum successorium beskou moet word.

Introduction: Plasmodium knowlesi cases is increasing in trend despite integrated vector management leading to morbidity and death. This study determines the association between P. knowlesi cluster with vector control, risk factors and its spatiotemporal distribution in cleared foci area in Sabah. Methods: This is a cross sectional study between 2017 and 2019 involving P. knowlesi cases in cleared foci registered in Vekpro Online. Simple logistic regression tests were performed using Statistics Package for the Social Sciences (SPSS) software and spatiotemporal distribution mapped using Quantum Geographic Information System (QGIS) software. Results: A total of 4,739 cases were analysed and high P. knowlesi cases reported in Ranau (17.1%), Keningau (12.8), Tenom (10.8%), Kudat (8.1%) and Kota Marudu (7.2%). Younger age groups (0 – 9 years), the Rungus ethnicity, and the use of vector control measures were positively associated with P. knowlesi clusters with the odds ratio of 2.421 (95% CI [1.596, 3.674]), 2.654 (95% CI [1.899, 3.708]), and 2.559 (95% CI [2.175, 3.011]) respectively. However, age group of 50-59 years, male gender, occupations related to agriculture, and employment in the private sector or self-employed were negatively associated with P. knowlesi clusters in cleared foci in Sabah with odds ratio between 0.478 and 0.771. The prevalence of P. knowlesi in cleared foci in Sabah were 36.2%, 44.09% per and 41.59% per 100,000 population in 2017, 2018 and 2019 respectively. The distribution differs in districts. Conclusion: Tailored measures and spatiotemporal distribution of P. knowlesi cluster is useful to reduce transmission and aids focus-based planning.

Introduction: The safety of migrant construction workers is increasingly becoming a worldwide issue, and addressing this requires identifying the critical relationship between safety climate and safety performance. This research aimed to evaluate this relationship and to give proper attention to enhance the overall safety performance of construction workers. Methods: To assess the relationship between safety climate and safety performance of migrant construction workers, a cross-sectional study was conducted among 141 migrant construction workers, from the 2 industrial zones of Abu Dhabi. Sociodemographic characteristics, safety climate, and safety performance were assessed by using a specifically designed questionnaire for the construction industry. The collected data were analysed by SPSS 27.0 using descriptive statistics and χ2 test. Results: The investigation’s findings revealed a positive correlation between the safety climate and safety performance. However, the weakest correlation was found in the workers’ comprehension of safety rules and procedures. Conclusion: Construction workers with less experience and lower education, aged 30 years or below, with no dependents to support, with smoking and drinking habits needs to be focused on the augmentation of their safety performance through safety awareness, relevant safety education, training and with the implementation of safety rules and procedures.
