UDC 517.9
We present new retarded nonlinear integral inequalities with mixеd powers. The obtained inequalities can be used to study the boundedness and global existence of the solutions of  integro-differential equation with delay and Volterra-type integral equation with delay.  These inequalities extend some  results available in the  literature.  Finally, we present two examples to demonstrate the usefulness of our main results.

Published: April 2023

Цель проведённого исследования связана с поиском технологических и технических достижений при проектировании установок по производству суспензии хлореллы для его дальнейшего широкого применения в животноводстве. В результате исследования предложено использовать современные технологии при производстве суспензии хлореллы, используемой для повышения иммунитета и снижения смертности молодняка сельскохозяйственных животных. Произведено сравнение использования существующих установок по выращиванию суспензии хлореллы, на примере установки УВИ-200 и новой установки, использующей в своей работе светодиодное освещение. Использование светодиодов с «красным» и «синим» спектром, применение контроллеров с обратной связью и компьютерного управления режимами культивации суспензии позволяет получать продукцию с данными характеристиками и минимумом использования квалифицированного труда. Кроме того, приведены данные себестоимости суспензии хлореллы.
Для культивирования хлореллы в условиях крестьянских хозяйств разработан и апробирован биореактор закрытого типа, выполненный в форме трубок. Высота аппарата зависит от объема необходимой суспензии хлореллы для выпойки крупно рогатого скота. Закрытая система позволяет осуществлять и контролировать следующие технологические операции: подача воздуха или газовой смеси, подача питательных растворов, автоматический контроль температуры и освещения, а также слив культуральной жидкости. За счет таких особенностей конструкции аппарата достигается свободный отток кислорода, оптимальное поглощение светодиодного освещения, исключается образование застойных зон за счет циркуляции суспензии, что в целом способствует снижению ресурсозатрат как энергетических, так и трудовых на процесс культивирования водоросли.
Aplicação dos Conceitos da Ecologia da Paisagem no Processo de Caracterização da Paisagem Urbana dos SELs

Published: April 2023

O planejamento urbano inadequado associado ao acelerado processo de urbanização têm provocado uma redução da qualidade ambiental, com áreas cada vez mais densificadas e carentes de espaços livres públicos de lazer e recreação. Diante disso, este trabalho objetiva realizar uma análise na escala urbana tendo como recorte espacial o Bairro Centro da Cidade de Santa Maria/RS - Brasil, sob a ótica da ecologia da paisagem para identificar o processo e caracterização da urbanização da área central do município e, observar como os remanescentes espaços livres intralotes se comportam na malha populacional densificada. A metodologia adotada tem como ponto principal a aplicação dos conceitos da Ecologia da Paisagem no processo de identificação e caracterização da paisagem – Sistema de espaço livres (SELs) intralotes. Os resultados obtidos demonstram que mais da metade da área do bairro Centro encontra-se ocupada por edificações, e em relação aos espaços livres intralote, 34,8% são privados e 14,5% públicos, sendo que destes, 12,1% constituem o sistema viário, ou seja, apenas 2,4% compõem espaços públicos de lazer e recreação. Estes resultados reforçam a carência no Plano Diretor municipal em relação à um planejamento urbano que inclua os SELs em suas diretrizes e estimule a preservação dos espaços verdes e da paisagem como um todo.
Avaliação do desempenho energético de habitação de interesse social no aglomerado Paiçandu – Maringá - Sarandi/PR
Authors: Gerola Gleison
Published: April 2023

Uma habitação deve atender condições mínimas de conforto térmico para que o usuário possa realizar suas tarefas: descanso e trabalho doméstico. Bem como, tenha um menor consumo energético durante o seu ciclo de vida. Nesse contexto, esse artigo tem como objetivo avaliar e classificar a envoltória de habitações de interesse social, nos Município de Maringá/PR, Sarandi/PR e Paiçandu/PR, por meio do método prescritivo descrito no volume 4 do Manual de Etiquetagem em Edificações - Procel Edifica (2013) e verificar alguns elementos arquitetônicos referentes ao desempenho térmico da edificação considerando a Norma de Desempenho ABNT NBR 15575: 2021. Os resultados demonstraram que as tipologias estudadas, para os três Municípios, apresentaram padrões mínimos de desempenho térmico limitado pela Norma ABNT NBR 15575: 2021, e apresentam classificação nível C, em uma escala de A até E do processo de etiquetagem em edificações. Referente à ABNT NBR 15575: 2021 aponta ineficiência das áreas de aberturas para ventilação e iluminação natural das tipologias arquitetônicas em estudo. Adequações construtivas nas fachadas, tais como mecanismos ajustáveis para proteção contra incidência dos raios solares nas aberturas e uso de cor clara na cobertura melhorariam o desempenho energético da envoltória dessas edificações.
Presença Discreta
Authors: Paz Daniel
Published: April 2023

O presente texto estuda o papel dos tecidos como dispositivos arquitetônicos durante a fase chamada “purista” do arquiteto Charles-Edouard Jeanneret-Gris, mais conhecido como Le Corbusier, dos anos 1920 e em alguns dos projetos da década seguinte. Se os tapetes ganharam atenção durante esse período, o mesmo não ocorreu com outros tipos de têxteis. Ausentes nos textos, apareciam discretamente, nos rincões das imagens – fotos, peças gráficas e croquis. O seu rastreio permite compreender as modalidades de emprego dos tecidos: para modulação espacial interna; nos recintos a céu aberto, sugerindo formações arquitetônicas (tetos, paredes, janelas), e para controle solar da envoltória construída, em muitas coisas “arquiteturas de papel”, viáveis apenas nos desenhos. Os tecidos foram trocados por outros dispositivos para desempenhar as mesmas funções, mais afins à expressão poética do arquiteto. Discretos que são, os tecidos previstos ou adotados nesse período são sinais sutis porém inequívocos dos seus experimentos espaciais e das vicissitudes de sua procura por espaço, luz e claridade.
Some permutation symmetric multiple hypotheses testing rules under dependent setup
Authors: Kundu Anupam , Bhandari Subir Kumar
Published: April 2023

The problem of multiple hypothesis testing with correlated test statistics is a very important problem in statistical literature. Specifically, we consider the case when the joint distribution of the test statistics is a multivariate normal distribution with an unknown mean vector and compound symmetric correlation structure. Our goal is to identify nonzero entries of the mean vector. Bogdan et al. (2011) solved this problem when test statistics are independent normals along with the study of asymptotic optimality in a Bayesian decision theoretic sense. The case under dependence was left as a challenging open problem. The solution is intuitive and permutation invariant, does not assume sparsity unlike Bogdan et al. (2011) and is validated through simulation studies.

Perjanjian ekstradisi sekarang ini yang diadakan antar negara, disebabkan adalah karena semakin berkembangnya zaman. Sekarang ini orang berbuat tindak pidana tidak takut lagi untuk melaMaka dalam hal ini penulis akan mengkaji dari segi Fiqih Siyasah. Bagaimanakah pandangan dari Fiqih Siyasah mengenai perjanjian ekstradisi ini. Jadi dalam hal ini bagaimanakah konsep perjanjian ekstradisi sekarang ini menurut Fiqih Siyasah. Apakah sudah sesuai atau belum. Dan juga mengenai prinsip-prinsip umum dari perjanjian ekstradisi itu sendiri, sudah sesuai dengan Fiqih Siyasah atau belum. Dilihat dari contoh perjanjian ekstradisi dengan negara lain, yang akan dilihat materi, konsep dari perjanjian tersebut menurut Fiqih Siyasah. Dan juga perjanjian ekstradisi itu sendiri dari segi pengertian, konsep dan lain-lainnya, sudah sesuai dengan Fiqih Siyasah atau tidak. Bahwa ternyata dalam Fiqih Siyasah sendiri telah mengenal adanya perjanijian ekstradisi. Mengenai prinsip-prinsip umum yang ada banyak yang telah sesuai secara substansial. Ada ketidak sesuaian, yaitu mengenai negara-negara yang dapat melakukan perjanjian ekstradisi. Dalam Fiqih Siyasah negara yang dapat mengadakan perjanjian ekstradisi adalah negara-negara yang termasuk dalam negara Darus Salam, sedangkan yang termasuk dalam Darul Kuffar tidak dapat mengadakan perjanjian ekstradisi dengan negara yang termasuk dalam Darus Salam.Selain itu dapat disimpulkan ada hal-hal yang kurang sesuai dengan Fiqih Siyasah, yaitu mengenai pelaku tindak kejahatan, yang mana dalam Fiqih Siyasah itu diperjelas mengenai apakah orang tersebut muslim, atau dzimmi. Sementara dalam perjanjian ekstradisi pada umumnya tidak secara jelas menyebutkan tentang pelaku kejahatan apakah dia itu muslim atau dzimmi.
PERSAMAAN GENDER KAUM FEMINISME DALAM PEMBAGIAN HARTA WARIS DITINJAU DARI PERSPEKTIF MADZHAB SYAFI’I
Authors: Mochammad Fahd Akbar  , Ari Prastiyo
Published: April 2023

Tulisan ini bertujuan menjelaskan konsep keadilan dalam hukum waris dari sudut pandang Islam perspektif madzhab Imam Syafi’i. Ilmu yang pertama kali hilang di tengah kaum muslimin adalah ilmu waris, sebagaimana yang telah disampaikan oleh Rasulullah Sallallahu alaihi wa salam. Tidak hanya sampai disitu, adanya usaha untuk merusak tatanan hukum waris dalam Islam dengan anggapan bahwa pembagian harta warisan bagi seorang anak laki-laki sebanding dengan dua orang anak perempuan merupakan sebuah bentuk kezaliman terhadap perempuan. Sehingga diperbolehkan untuk melakukan modifikasi terhadap hukum waris Islam. Penelitian ini adalah library research (riset kepustakaan) dengan menggunakan pendekatan deskriptif analitis. Dengan kesimpulan bahwa makna keadilan dalam hukum waris Islam harus mengikuti ketentunan Allah Subhanahu wa ta’ala bukan pembagian yang sama rata. Dibalik pembagian waris dalam Islam mengandung keadilan yang bersifat universal ditinjau dari sisi teologi, ekonomi, sosial.
MEDIASI SEBAGAI SOLUSI ALTERNATIF KONFLIK KELUARGA PERSPEKTIF HUKUM ISLAM DAN HUKUM PROGRESIF

Published: April 2023

Mediation is a fast, cheap, and satisfying alternative in resolving disputes. In reality, however, the opposite of these hypotheses occurs. As a result, a holistic understanding of mediation is required so that in the future, mediation can exist progressively in handling, reducing, and resolving family conflicts, thereby achieving the ideals of sakinah mawaddah warahmah in the family. The purpose of this paper is to analyse mediation through the perspective of Islamic law and progressive law. The analysis’s findings, which were obtained using normative methods and an analytical-descriptive approach, demonstrate that, from the perspective of Islamic law, the current model of mediation is the result of the integration of sulh and tahkim which the process of disputing parties negotiating with the assistance of a mediator who facilitates and controls the process to reach a consensual agreement. Sulh describes the characteristics of reaching a consensual agreement, while tahkim describes the characteristics of appointing a third party as a mediator. Meanwhile, according to progressive law, mediation is a creative, innovative, productive, fair, and dynamic means of resolving family conflicts. So mediation exists and is progressive as an institution that serves humans and solves problems in order for them to be happy.

Published: April 2023

Aim: The purpose of the study is to present one of the prerequisites for maintaining of social order, the desire for justice to prevail, through a social science approach to the concept of order.Methodology: During the exposition the author separeted the conceptions of order in natural and social sciences, while at the same time pointing out the historical nature of this distinction. Through the ideas of Aristotle, Augustine and Hedley Bull on social order, the author has arrived at the necessary question of justice.Findings: At a given level of organisation of human communities, the maintenance of (social) order can be ensured by the application of justice in a given historical period.Value: The unconventional approaches of law enforcement science provide an opportunity to see the forms of behavior raised to the individual and community level, expressed in the life conditions that needed to be regulated, on a border horizon and in deeper contexts. The knowledge acquired in this way is necessary to determine the functioning of institutionalized policing.
Chatbotok a kormányzati platformok szolgálatában
Authors: Hohmann Balázs
Published: April 2023

Aim: Within government activities, we have seen a marked digitalisation process in the last few years, both at domestic and international level. In this environment, human activity is naturally replaced by software solutions, and this is true for the governmental interaction with clients through government platforms. The aim of this study is to explore the conditions for the use of chatbot communication forms in public administrations, by examining the case where a government platform is used for the administrative procedures. The study also aims to explore and systematise the impact of these solutions on the transparency of the government platform and the administrative procedures carried out through it.Methodology: Critically analyse national and European legal sources of the subject, as well as implemented and planned practical solutions, in order to formulate a set of requirements and recommendations.Findings: The set of requirements for administrative procedures identifies a number of requirements that can be interpreted in the context of the use of chatbots as a communication method. These can also be interpreted in terms of legal compliance, and are not just recommendations or good practices. The impact of a software solution on transparency is twofold: on the one hand, it can greatly increase the transparency of the platform and the process, due to its speed and interactivity, and on the other hand, it can reduce it, depending on the degree of IT sophistication.Value: The most important new knowledge of the study, which can be interpreted in scientific terms, is that it defines the administrative requirements for chatbots as software solutions based on artificial intelligence, when they are used for the administration and communication of administrative procedure via government platforms. An important new concept of the study is the establishment of the equivalence principle, which applies when the human administrator’s contact and information tasks are replaced by a software solution on the platform in their entirety, without any choice.

We present the results of a systematic search for candidate quiescent galaxies in the distant universe in 11 JWST fields with publicly available observations collected during the first 3 months of operations and covering an effective sky area of ∼145 arcmin2. We homogeneously reduce the new JWST data and combine them with existing observations from the Hubble Space Telescope. We select a robust sample of ∼80 candidate quiescent and quenching galaxies at 3 < z < 5 using two methods: (1) based on their rest-frame UVJ colors, and (2) a novel quantitative approach based on Gaussian mixture modeling of the near-UV − U, U − V, and V − J rest-frame color space, which is more sensitive to recently quenched objects. We measure comoving number densities of massive (M
⋆ ≥ 1010.6
M
⊙) quiescent galaxies consistent with previous estimates relying on ground-based observations, after homogenizing the results in the literature with our mass and redshift intervals. However, we find significant field-to-field variations of the number densities up to a factor of 2–3, highlighting the effect of cosmic variance and suggesting the presence of overdensities of red quiescent galaxies at z > 3, as could be expected for highly clustered massive systems. Importantly, JWST enables the robust identification of quenching/quiescent galaxy candidates at lower masses and higher redshifts than before, challenging standard formation scenarios. All data products, including the literature compilation, are made publicly available.
Investigating the Effect of Solar Ambient and Data Characteristics on Ca ii K Observations and Line Profile Measurements

Published: April 2023

We analyzed state-of-the-art observations of the solar atmosphere to investigate the dependence of the Ca ii K brightness of several solar features on spectral bandwidth and spatial resolution of the data. In particular, we study data obtained at the Swedish Solar Telescope with the Crisp Imaging Spectropolarimeter and Chromospheric Imaging Spectrometer instruments. The analyzed data, which are characterized by a spectral bandwidth of 0.12 Å and a spatial resolution of 0.″078, were acquired close to the disk center by targeting a quiet-Sun area and an active region. We convolved the original observations with Gaussian kernels to degrade their spectral bandwidth and spatial resolution to the instrumental characteristics of the most prominent series of Ca ii K observations available to date. We then studied the effect of data degradation on the observed regions and on parameters derived from Ca ii K line measurements that are largely employed as diagnostics of the solar and stellar chromospheres. We find that the effect of degrading the spectral resolution of Ca ii K observations and line profiles depends on both the employed bandwidth and observed solar region. Besides, we found that the spatial degradation impacts the data characterized by a broad bandwidth to a larger extent compared to those acquired with a narrow band. However, the appearance of the observed solar regions is only slightly affected by the spatial resolution of data with bandwidths up to 1 Å and in the range [3,10] Å. Finally, we derived relationships that can be used to intercalibrate results from observations taken with different instruments in diverse regions of the solar atmosphere.
Finding the Nash equilibria of $ n $-person noncooperative games via solving the system of equations
Authors: Li Huimin , Xiang Shuwen , Xia Shunyou , Huang Shiguo
Published: April 2023

In this paper, we mainly study the equivalence and computing between Nash equilibria and the solutions to the system of equations. First, we establish a new equivalence theorem between Nash equilibria of $ n $-person noncooperative games and solutions of algebraic equations with parameters, that is, finding a Nash equilibrium point of the game is equivalent to solving a solution of the system of equations, which broadens the methods of finding Nash equilibria and builds a connection between these two types of problems. Second, an adaptive differential evolution algorithm based on cultural algorithm (ADECA) is proposed to compute the system of equations. The ADECA algorithm applies differential evolution (DE) algorithm to the population space of cultural algorithm (CA), and increases the efficiency by adaptively improving the mutation factor and crossover operator of the DE algorithm and applying new mutation operation. Then, the convergence of the ADECA algorithm is proved by using the finite state Markov chain. Finally, the new equivalence of solving Nash equilibria and the practicability and effectiveness of the algorithm proposed in this paper are verified by computing three classic games.
Flat modules and coherent endomorphism rings relative to some matrices
Authors: Zeng Yuedi
Published: April 2023

Let $ N $ be a left $ R $-module with the endomorphism ring $ S = \text{End}(_{R}N) $. Given two cardinal numbers $ \alpha $ and $ \beta $ and a matrix $ A\in S^{\beta\times\alpha} $, $ N $ is called flat relative to $ A $ in case, for each $ x\in l_{N^{(\beta)}}(A) = \{u\in N^{(\beta)} \mid uA = 0\} $, there are a positive integer $ k $, $ y\in N^{k} $ and a $ k\times \beta $ row-finite matrix $ C $ over $ S $ such that $ CA = 0 $ and $ x = yC $. It is shown that $ N_{S} $ is flat relative to a matrix $ A $ if and only if $ l_{N^{(\beta)}}(A) $ is generated by $ N $. $ S $ is called left coherent relative to $ A $ if Ker$ (_{S}S^{(\beta)}\to _{S}S^{(\beta)}A) $ is finitely generated. It is shown that $ S $ is left coherent relative to $ A $ if and only if Hom$ _{R}(N, l_{N^{n}}(A)) $ is a finitely generated left $ S $-module if and only if $ l_{N^{n}}(A) $ has an add$ (N) $-precover (add$ (N) $ denotes the category of all direct summands of finite direct sums of copies of $ _{R}N $). Regarding applications, new necessary and sufficient conditions for epic (monic, having the unique mapping property) add$ (N) $-precovers of $ l_{N^{(\beta)}}(A) $ are investigated. Also, some new characterizations of left $ n $-semihereditary rings and von Neumann regular rings are given.

Published: April 2023

The next generation parallel computers are the keys to achieve exascale performance, whereas sequential computers have already been saturated. In order to achieve this mighty target of exascale computing, one of the main challenges is the reduction of power consumption along with achieving suitable performance. Energy efficiency is a key feature to ensure the trade-off between the performances over the required power usages. Hence, to focus on those issues, the target of this article is to analyze the performance versus power usage trade-off for the conventional networks like- Mesh and Torus. High degree networks show much better performance than the low degree of networks. However, high degree networks require higher power usage for their high degree of interconnected links. This article showed that with zero load latency, the 3D Torus could show about 57.07% better performance than a 2D Torus. On the other hand, a 2D Mesh network requires about 24.22% less router power usage than the 3D Mesh, & 5D Torus requires about 66.8% higher router power usage than a 3D Torus network.

Published: April 2023

Treatment of influenza and its complications is a major challenge for healthcare systems. Pyrazine is one drug used in treating influenza. Aspergillic acid is major antibiotic constituent in pyrazine compounds mined from Aspergillus flavus' final stage. This stage of flavus is detected through color change forming a pale-yellow crystal structure. Detection of the same is complex and demands an experienced fraternity to continuously monitor the growth of fungus and identify its color change. However, researches proved that the task needs to be perfect and a tiny human error leads to a catastrophe in antibiotic creation. To avoid these flaws, druggists make a huge investment on costly equipment for accurate detection. To overcome these drawbacks, this article proposes a hybrid quantum convolutional neural network that predicts various stages of the fungus from the microscope's sample. To train the network, about 47,000 samples were poised under typical lab settings. The proposed system was tested in usual conditions and positively isolated the mature samples with 96% efficiency.

Authors: Li Ning , Lu Jingcai , Cheng Xu , Tian Zhi
Published: April 2023

Aiming at the problems of low accuracy and high loss rate when the traditional target tracking (TT) method is applied to the TT of the moving operation of the transmission line, a transmission line based on an inspection robot and edge computing (EC) is proposed: the mobile job TT method. First, the basic framework of the TT algorithm is proposed, relying on the edge device to develop the TT system for mobile operations on the transmission line. Video information is collected by an intelligent inspection robot and sent to the target tracking system in the edge device for processing to obtain accurate data. Then, the gradient disappearance and explosion problems caused by the increase of network depth are solved by using the deep residual network. The traditional deep residual network is improved by introducing the improved bidirectional feature reinforcement network and the classification and regression subnet. The loss of position texture information is remedied, and the accurate tracking of the moving target on transmission line is realized. Finally, the real-time data acquisition of mobile operation target is realized by using an intelligent inspection robot, and the experimental verification is conducted. The proposed algorithm is compared and analyzed against the three other algorithms using the same data set through simulation experiments. The results show the precision, recall rate, accuracy, and comprehensive evaluation index F1 value of the proposed algorithm rank highest, reaching 93.8%, 90.2%, 83.8%, and 89.8%, respectively, compared with the other algorithms.

In this research, a unique subspace data driven control for linear parameter changing system with scheduling parameters is presented. This control paves the way for investigating the nonlinear system based on the results regarding the linear system that are already known. Only the data matrix is utilized to represent the output prediction value in the future various time instants, while the input-output observation data matrix is used to identify Markov parameters in the form of state space forms. The cost function in data-driven control is then adjusted using the output prediction value. The optimal control input value of this quadratic cost function is solved using a parallel distribution technique, and the algorithm's iterative convergence is thoroughly examined. Finally, the DC motor, whose mass distribution factor is considered to be one linear parameter varying system, is controlled using the suggested subspace data driven control approach.

Published: April 2023

While mobile application (app) software is becoming increasingly important in people's daily lives, researchers have the limitation of understanding the details of user operations inside the app. With the update of the Android system and application user interface, relying on manually defined user operation event templates or modifying the app source code can no longer meet the needs of fine-grained user operation analysis in multiparallel applications. In this article, a novel method is proposed for effectively analyzing user operations in parallel apps based on the temporal context of user operation sequences. The authors provide a general framework in the Android system to parse out fine-grained user operations. In addition, the authors build a deep learning model with LSTM-TextCNN to complete user operations in parallel app from global temporal context and app temporal context. The authors collected 240k operations of 12 users over a month. Comparative experiments with a baseline show that the proposed method can efficiently and accurately analyze parallel app user operations.

Internet of everything (IoE) has the power of reforming the healthcare sector - various medical devices, hardware, and software applications that are interconnected, tendering a massive volume of data. The huge interconnected medical-based network is prone to significant malicious attacks that can modify the medical data being communicated and transferred. IoE permits dynamic two-way communication and empowers the network with intellect, sophisticated data handling, caching, and allocation mechanisms. In this paper, an improvement in the conventional variable-sized detector generation for healthcare - IVD-IMT algorithm under Artificial Immune System (AIS) based Intrusion Detection System (IDS) capable of handling enormous data generated by the IoE medical network is proposed. Algorithm efficiency is dependent on two performance metrics - detection rate and false alarm rate. The input parameters were tuned using synthetic datasets and then tested over the NSL-KDD dataset. The research lays emphasis on lowering the false alarm rate without compromising on the detection rate.

Published: April 2023

The main novelty of this paper is proposing artificial intelligence (AI) to manage behavioural biases in the financial decision-making process. An empirical study by Kahneman and Tversky identifies the evidence of behavioural biases in the investment decision-making process: a reversal of an established tenet in traditional finance. Financial planners are vulnerable to behavioural biases and are therefore unable to provide optimal investment solutions for their clients. Identifying the limitations of current practice, this research attempts to address how AI can help financial planners in subduing their behavioural biases and proposes the adoption of AI in financial planning services to circumvent behavioural biases. In recent years, AI has attained significant efficacy and has proven to be efficacious through supervised and unsupervised learning. Applying these AI techniques in mitigating behavioural biases, this study confirms that the backpropagation within the neural network and deep reinforcement learning can help overcome confirmation and hindsight biases.

IL-6 plays a fundamental role in T cell differentiation and is strictly controlled by surface expression and shedding of IL-6R. IL-6 also acts on other cells that might affect T cell maturation. To study the impact of cell-autonomous and uncontrolled IL-6 signaling in T cells, we generated mice with a constitutively active IL-6R gp130 chain (Lgp130) expressed either in all T cells (Lgp130 × CD4Cre mice) or inducible in CD4+ T cells (Lgp130 × CD4CreERT2 mice). Lgp130 × CD4Cre mice accumulated activated T cells, including TH17 cells, in the lung, resulting in severe inflammation. Tamoxifen treatment of Lgp130 × CD4CreERT2 mice caused Lgp130 expression in 40–50% of CD4+ T cells, but mice developed lung disease only after several months. Lgp130+ CD4+ T cells were also enriched for TH17 cells; however, there was concomitant expansion of Lgp130− regulatory T cells, which likely restricted pathologic Lgp130+ T cells. In vitro, constitutive gp130 signaling in T cells enhanced but was not sufficient for TH17 cell differentiation. Augmented TH17 cell development of Lgp130+ T cells was also observed in Lgp130 × CD4CreERT2 mice infected with Staphylococcus aureus, but gp130 activation did not interfere with formation of TH1 cells against Listeria monocytogenes. Lgp130+ CD4+ T cells acquired a memory T cell phenotype and persisted in high numbers as a polyclonal T cell population in lymphoid and peripheral tissues, but we did not observe T cell lymphoma formation. In conclusion, cell-autonomous gp130 signaling alters T cell differentiation. Although gp130 signaling is not sufficient for TH17 cell differentiation, it still promotes accumulation of activated T cells in the lung that cause tissue inflammation.

Published: April 2023

Background: Tuberculosis (TB) related mortality remains a serious impediment in ending TB epidemic.

Objective: To estimate survival probability and identify predictors, causes and conditions contributing to mortality among TB patients in Vihiga County.

Methods: A cohort of 291 patients from 20 purposively selected health facilities were prospectively considered. Data was obtained by validated questionnaires through face-to-face interviews. Survival probabilities were estimated using Kaplan-Meier method while Cox proportional hazard model identified predictors of TB mortality through calculation of hazard ratios at 95% confidence intervals. Mortality audit data was qualitatively categorized to elicit causes and conditions contributing to mortality.

Results: 209 (72%) were male, median age was 40 (IQR=32-53) years while TB/HIV coinfection rate was 35%. Overall, 45 (15%) patients died, majority (78% (log rank<0.001)) during intensive phase. The overall mortality rate was 32.2 (95% CI 23.5 - 43.1) deaths per 1000 person months and six months’ survival probability was 0.838 (95% CI, 0.796-0.883). Mortality was higher (27%) among HIV positive than HIV negative (9%) TB patients. Independent predictors of mortality included; comorbidities (HR = 2.72, 95% CI,1.36–5.44, p< 0.005), severe illness (HR=5.06, 95% CI,1.59–16.1, p=0.006), HIV infection (HR=2.56, 95%CI,1.28–5.12, p=0.008) and smoking (HR=2.79, 95% CI,1.01–7.75, p=0.049). Independent predictors of mortality among HIV negative patients included; comorbidities (HR = 4.25, 95% CI; 1.15-15.7, p = 0.03) and being clinically diagnosed (HR = 4.8, 95% CI; 1.43-16, P = 0.01) while among HIV positive; they included smoking (HR = 4.05, 95% CI;1.03-16.0, P = 0.04), severe illness (HR = 5.84, 95% CI; 1.08-31.6, P = 0.04), severe malnutrition (HR = 4.56, 95% CI; 1.33-15.6, P = 0.01) and comorbidities (HR = 3.04, 95% CI; 1.03-8.97, p = 0.04). More than a half (52%) of mortality among HIV positive were ascribed to advancedHIV diseases while majority of (72%) of HIV negative patients died to TB related lung disease. Conditions contributing to mortality were largely patient and health system related.

Conclusion: Risk of TB mortality is high and is attributable to comorbidities, severe illness, HIV and smoking. Causes and conditions contributing to TB mortality are multifaceted but modifiable. Improving TB/HIV care could reduce mortality in this setting.

Published: April 2023

Aims: This paper aimed to investigate the antiviral drugs against Sars-Cov-2 main protease (MPro) using in silico methods.

Material and Method: A search was made for antiviral drugs in the PubChem database and antiviral drugs such as Bictegravir, Emtricitabine, Entecavir, Lamivudine, Tenofovir, Favipiravir, Hydroxychloroquine, Lopinavir, Oseltamavir, Remdevisir, Ribavirin, Ritonavir were included in our study. The protein structure of Sars-Cov-2 Mpro (PDB ID: 6LU7) was taken from the Protein Data Bank (www.rcsb. Org) system and included in our study. Molecular docking was performed using AutoDock/Vina, a computational docking program. Protein-ligand interactions were performed with the AutoDock Vina program. 3D visualizations were made with the Discovery Studio 2020 program. N3 inhibitor method was used for our validation.

Results: In the present study, bictegravir, remdevisir and lopinavir compounds in the Sars-Cov-2 Mpro structure showed higher binding affinity compared to the antiviral compounds N3 inhibitor, according to our molecular insertion results. However, the favipiravir, emtricitabine and lamuvidune compounds were detected very low binding affinity. Other antiviral compounds were found close binding affinity with the N3 inhibitor.

Conclusion: Bictegravir, remdevisir and lopinavir drugs showed very good results compared to the N3 inhibitor. Therefore, they could be inhibitory in the Sars Cov-2 Mpro target.

Published: April 2023

Introduction: Pelvic organ prolapse (POP) is associated with negative physical, social, psychological, and sexual experiences. There is paucity of data in low and middle income countries like Uganda. The purpose of this study was to describe clinical characteristics and outcomes of patients undergoing surgery for POP from 2007 to 2016.

Methods: The study was conducted at Mulago National Referral Hospital from 2014 to 2016. We conducted a retrospective review of the urogynecology surgical records using a standardized medical record abstraction form. Data of 222 POP patients were abstracted and managed using REDCap. Analysis was performed using Stata statistical software, v14.

Results: The mean participant age and parity was 57 years and 7 respectively. Ninety four percent of participants presented with a mass protruding from the vagina, 38% with uterine prolapse and 32% with cystocoele. Anaemia and hypertension were common comorbidities. Women underwent a variety of surgery types, and 35% experienced persistent pain post-operatively. At hospital discharge, 83% had achieved either complete resolution or improvement in their condition.

Conclusions: Measures encouraging presentation for care as soon as symptoms are experienced and reduction of total fertility rate will be beneficial. Patients with POP should be routinely screened for anaemia and hypertension.

Published: April 2023

Background: Ovarian tumours are the most lethal of all gynaecological cancers and they are usually diagnosed in advanced stages when the `prognosis is very poor.

Objective: To determine the pattern of ovarian lesions, their frequency, presentation, and associated clinical symptoms in Uyo, Nigeria.

Methods: A 10-year retrospective study of all ovarian specimens that were surgically removed and histologically diagnosed.

Results: The patients were between the ages of 5 and 73 years with median age of 34.1 years. Benign tumours occurred most commonly among the 20–39-year age group (31.3%) while malignant tumours were predominant among those aged 50-69 years (10.0%). Surface epithelial tumours (45.4%) were the most common neoplastic tumours while the mature cystic teratoma (33.2%) was the most common tumour overall. Surface epithelial malignancies accounted for 70.6% of all ovarian malignancies and the serous cyst adenocarcinoma (10.2%) was the most common surface epithelial tumour as well as the most common malignant tumour.

Conclusion: There has been an increase in the number of malignant ovarian specimens in our centre. Though surface epithelial tumours were the most common category of ovarian tumours, overall, the mature cystic teratoma was the most common tumour. Serous cyst adenocarcinoma was the most common surface epithelial tumour and the most common malignant tumour.
