Spherically Symmetric C3 Matching in General Relativity
Authors: Quevedo Hernando
Published: September 2023

We study the problem of matching interior and exterior solutions to Einstein’s equations along a particular hypersurface. We present the main aspects of the C3 matching approach that involve third-order derivatives of the corresponding metric tensors in contrast to the standard C2 matching procedures known in general relativity, which impose conditions on the second-order derivatives only. The C3 alternative approach does not depend on coordinates and allows us to determine the matching surface by using the invariant properties of the eigenvalues of the Riemann curvature tensor. As a particular example, we apply the C3 procedure to match the exterior Schwarzschild metric with a general spherically symmetric interior spacetime with a perfect fluid source and obtain that on the matching hypersurface, the density and pressure should vanish, which is in accordance with the intuitive physical expectation.

Background: Human respiratory syncytial virus (hRSV) is a key contributor to lower respiratory tract infections (LRTIs), affecting children aged 0–5 years and often leading to outpatient visits, emergency department utilization, and hospitalization. With the development of hRSV vaccines for mitigation, understanding the epidemiological impact of hRSV infections among 0–5-year-old pediatric outpatients in Italy is crucial. Methods: This systematic review conducted searches on PubMed, Embase, Scopus, and the International HTA Database, yielding 20,845 English and Italian records from January 2000 to July 2022. Results: Six eligible articles were identified following inclusion and exclusion criteria. These studies demonstrated hRSV-positivity proportions ranging from 18% to 41% in pediatric outpatients with respiratory infections. However, data comparability was hindered by diverse diagnostic approaches, data sources, sample populations, and study designs. Notably, hRSV-positivity showed temporal variability, rising from 23.8% (2001–2002) to 40.6% (2019–2020). This trend could stem from evolving epidemiological factors, heightened clinician awareness in hRSV diagnosis, or more sensitive molecular techniques. Conclusion: As the first review of its kind, this study underscores the need for more comprehensive data to inform effective preventive strategies against hRSV-related burdens in pediatric outpatients.

CD4+ T cells have been found to play critical roles in the control of both acute and chronic Toxoplasma infection. Previous studies identified a protective role for the Toxoplasma CD4+ T cell-eliciting peptide AS15 (AVEIHRPVPGTAPPS) in C57BL/6J mice. Herein, we found that immunizing mice with AS15 combined with GLA-SE, a TLR-4 agonist in emulsion adjuvant, can be either helpful in protecting male and female mice at early stages against Type I and Type II Toxoplasma parasites or harmful (lethal with intestinal, hepatic, and spleen pathology associated with a storm of IL6). Introducing the universal CD4+ T cell epitope PADRE abrogates the harmful phenotype of AS15. Our findings demonstrate quantitative and qualitative features of an effective Toxoplasma-specific CD4+ T cell response that should be considered in testing next-generation vaccines against toxoplasmosis. Our results also are cautionary that individual vaccine constituents can cause severe harm depending on the company they keep.

The immunological genes that may interact with inflammatory postpartum diseases in Italian buffaloes were examined in this study. A total number of 120 female Italian buffaloes (60 normal and 60 with inflammatory reproductive diseases) were employed. Each buffalo’s jugular vein was pierced to get five milliliters of blood. To obtain whole blood and extract DNA and RNA, the blood was placed within tubes containing sodium fluoride or EDTA anticoagulants. The immunological (IKBKG, LGALS, IL1B, CCL2, RANTES, MASP2, HMGB1, and S-LZ) genes’ nucleotide sequence differences between healthy buffaloes and buffaloes affected by inflammatory reproductive diseases were found by employing PCR-DNA sequencing. According to Fisher’s exact test (p ˂ 0.01), there were noticeably different probabilities of all major nucleotide changes spreading among buffalo groups with and without reproductive problems. Buffaloes were significantly more likely to express the examined genes when they had inflammatory reproductive diseases. The outcomes might support the significance of these markers’ nucleotide variations and gene expression patterns as indicators of the prevalence of inflammatory reproductive disorders and provide a workable buffalo management policy.
Diagnosis codes underestimate chronic kidney disease incidence compared with eGFR-based evidence: a retrospective observational study of patients with type 2 diabetes in UK primary care
Authors: Sisk Rose , Cameron Rory , Tahir Waqas , Sammut-Powell Camilla
Published: September 2023

Background

Type two diabetes (T2D) is a leading cause of both chronic kidney disease (CKD) and onward progression to end-stage renal disease. Timely diagnosis coding of CKD in patients with T2D could lead to improvements in quality of care and patient outcomes.

Aim

To assess the consistency between estimated glomerular filtration rate (eGFR)-based evidence of CKD and CKD diagnosis coding in UK primary care.

Design & setting

A retrospective analysis of electronic health record data in a cohort of people with T2D from 60 primary care centres within England between 2012 and 2022.

Method

We estimated the incidence rate of CKD per 100 person–years using eGFR-based CKD and diagnosis codes. Logistic regression was applied to establish which attributes were associated with diagnosis coding. Time from eGFR-based CKD to entry of a diagnosis code was summarised using the median and interquartile range.

Results

The overall incidence of CKD was 2.32 (95% confidence interval [CI] = 2.24 to 2.41) and significantly higher for eGFR-based criteria than diagnosis codes: 1.98 (95% CI = 1.90 to 2.05) versus 1.06 (95% CI = 1.00 to 1.11), respectively;P<0.001. Only 45.4% of CKD incidences identified using eGFR-based criteria had a corresponding diagnosis code. Patients who were younger, had a higher CKD stage (G4), had an observed urine albumin-to-creatinine ratio (A1), or no observed HbA1c in the past year were more likely to have a diagnosis code.

Conclusion

Diagnosis coding of patients with eGFR-based evidence of CKD in UK primary care is poor within patients with T2D, despite CKD being a well-known complication of diabetes.

The problem with most mining companies is a lack of information on the availability of ready-to-use (purchase or rent) heavy equipment and information on providers of heavy equipment spare parts, heavy equipment owners who have difficulty finding a market to sell or rent their equipment. Transaction processes that have been taking place so far have used telephone lines, chats and person-to-person emails where this is felt to be less effective and efficient. This research methodology contains stages regarding the process and procedure of data collection, method analysis procedures, system development procedures as well as the time and place of research. The purpose of this study is to implement the user based filtering recommendation machine method on mining equipment rental systems. The results of the study show that the recommendation system that has been built has succeeded in providing appropriate recommendations to customers who have made mining equipment rental transactions based on the parameters of the results of the recommendation accuracy test. The algorithm of the user based filtering recommendation engine method can be applied to the mining tool recommendation system that has been built. Based on testing the accuracy of the recommendation values, each value obtained in the calculation of the Mean Absolute Error (MAE) is 0.00936 so that the resulting recommendation accuracy is 99.99%. Then for the value of the Mean Absolute Percentage Error (MAPE) obtained a value of 27.84%, and for the value of the Mean Squared Error (MSE) obtained was 0.01702.

Published: September 2023

Penyakit alzheimer adalah penyakit yang menyerang sistem saraf di dalam otak. Penyakit ini dapat menyebabkan terganggunya aktivitas sehari-hari, ingatan yang tidak terorganisir, dan berkurangnya daya ingat. Deteksi dini penyakit alzheimer dapat memanfaatkan pendekatan matematis menggunakan data mining. Data mining memiliki model-model klasifikasi yang dapat digunakan untuk mendeteksi dini penyakit alzheimer. Beberapa algoritma yang dapat digunakan untuk klasifikasi diantaranya adalah C4.5 dan Adaptive Boosting (AdaBoost) yang diterapkan pada penelitian ini untuk mengklasifikasikan penyakit alzheimer. Perbandingan kedua algoritma ini bertujuan untuk memperoleh algoritma mana yang paling tepat dalam klasifikasi penyakit alzheimer. Untuk menguji kedua algoritma ini digunakan dua teknik pengujian yaitu percentage split dan k-fold cross validation. Pada percentage split dipilih ukuran split sebesar 80% untuk data latih dan 20% sebagai data uji dan k-fold cross validation dipilih nilai k sebesar 10. Hasil penerapan dari kedua algoritma diperoleh bahwa untuk k-fold cross validation bekerja lebih baik dibandingkan dengan percentage split. Hal ini dikarenakan k-fold cross validation meningkatkan persentase nilai presisi, recall, dan akurasi dari masing-masing algoritma. Untuk kinerja masing-masing algortima, AdaBoost dalam penggunaanya bekerja lebih baik dibandingkan dengan C4.5 dengan nilai presisi, recall dan akurasi secara berturut-turut, yaitu 91.5%, 91% dan 91.15%. Dari hasil yang diperoleh dapat disimpulkan bahwa algoritma AdaBoost dengan teknik k-fold cross validation memiliki performa yang paling baik dalam melakukan klasifikasi penyakit alzheimer dibandingkan algoritma dan teknik pengujian lainnya.
Choix de langues et rôles discursifs dans une conversation familiale italo-canadienne ["Alene nu Stɛ]m :a fa la fjɛ]r”]
Authors: Silvestri Elena
Published: September 2023

La conversation de notre famille présente une situation bilingue intéressante. Les parents ont gardé leur langue (italien) et les enfants ont adopté la langue du pays d'accueil (anglais). Il y a donc deux langues de base dans la conversation, avec possibilité d'alternance codique, définie ici par rapport au locuteur (italien-anglais pour les parents et anglais-italien pour les enfants). L'alternance codique est un élément essentiel dans la dynamique interactionnelle. Il y a un "jeu" entre statuts, rôles et places discursives des participants et les langues ou le choix de langue. Un changement de langue peut marquer un changement de rôle ou de place (le statut étant difficilement interchangeable). On se sert de la "langue de l'autre" pour l'imiter, pour assumer son rôle ou pour faire savoir qu'on change de place discursive. Cela produisant d'intéressants effets de continuité et de rupture au niveau linguistique aussi bien qu'au niveau relationnel.
La famille comme lieu dialectal : un refuge revisité
Authors: Eloy Jean-Michel
Published: September 2023

On réexamine deux postulats de nombreux travaux de dialectologie (géographique ou sociale). L'un serait qu'il existe des parlers authentiques et d'autres moins, l’autre que pour observer l'authentique, il faut effacer l’observateur. On montre là-dessus l'unité de Rousselot et de Labov. A ces postulats s’opposent les propositions de Le Page-Tabouret-Keller, qui donnent le statut anthropologique d'"acte d’identité" à la systémacité linguistique (la "focalisation linguistique"), et celle de l'ethnologue G.AIthabe, pour qui la construction de l'objet d'enquête se lit dans les rapports de l'enquêteur aux informateurs. Sur le terrain, l'approche d'une famille par trois voies différentes permet de montrer que le picard parlé en famille est en partie un élément construit de la représentation de soi, pour soi et pour les autres : le fonctionnement langagier est pertinent, mais non la variété, construit social (distinguée du répertoire linguistique).
Hungarian vs. American mediators and how to make communities more resilient
Authors: Schmidt Laura
Published: September 2023

Restorative justice practices are used in a wide array of criminal offence cases globally as it puts the need of victims and the community at the centre of the proceedings and focuses on repair and rehabilitation rather than judgement and punishment.
This study focuses on the different experiences of mediators in Hungary and in Bloomington, Indiana, United States. Two local government offices in Hungary and a non-profit organization, called Community Justice and Mediation Center (CJAM) were selected for this study. Six Hungarian and five American mediators from the local government offices and CJAM were interviewed in person and online.
Analyzing the interviews, we find that there are fundamental differences between the definitions, legislation, and the practices used in the two jurisdictions. The training of mediators is found to be similar in both countries but the way restorative practices are used is different. The system in Bloomington allows the process to be more flexible whilst in Hungary, the high caseloads and strict timeframes of the prosecutor’s office demand that cases be very quick and efficient. This is likely the reason why at CJAM, co-mediation is the norm, with at least two but sometimes three or four facilitators working on a case, while in Hungary co-mediation only happens in the most complex cases.
However, it is apparent that the goal of mediation and restorative justice meetings is the same in both Hungary and Bloomington: to repair the harms and to help build a better community.

Published: September 2023

Objetivo: presentar una causa rara de obstrucción duodenal como es el sindrome de arteria mesentérica superior (SAMS). Materiales y Método: se presentan tres casos clínicos de sindrome de SAMS. Resultados: el tratamiento médico y nutricional fue exitoso en los primeros dos casos, mientras que en el último fue necesario realizar una derivación quirúrgica. Discusión: en este sindrome, el ángulo aortomesentérico normal se encuentra disminuído, causando la compresión de la tercera porción del duodeno entre la aorta y la arteria mesentérica superior. Esto determina una obstrucción duodenal que se ve más frecuentemente en pacientes con pérdida importante y rápida de peso. Esto determina alteraciones hidroelectrolíticas y desnutrición severas. El tratamiento médico consiste en soporte nutricional y corrección de anormalidades hidroelectrolíticas. Los procedimientos quirúrgicos se reservan frente a los casos de falla del tratamiento médico. Conclusión: el SAMS es una entidad poco frecuente y un reto diagnóstico. El cuadro clínico puede ser grave con desnutrición severa y trastornos hidroelectrolíticos que ponen en riesgo la vida del paciente. El soporte hidroelectrolítico y nutricional, junto a la duodenoyeyunostomía, son los tratamientos de elección.

Published: September 2023

Introducción: Existe una controversia acerca del mejor enfoque para el tratamiento de la apendicitis aguda no complicada. Este metaanálisis buscó evaluar la eficacia, recurrencia de la patología, presencia de complicaciones mayores, y duración de la estancia hospitalaria en adultos con apendicitis aguda no complicada.Materiales y Métodos: Se realizó una búsqueda sistemática de ensayos clínicos aleatorizados en las bases de datos PubMed, Scopus, Web of Science, Embase y Cochrane Library hasta finales de octubre del 2022. El riesgo de sesgo y calidad de los estudios incluidos en el estudio fueron evaluados mediante la herramienta RoB 2.0. de la Colaboración Cochrane. La síntesis de datos fue realizada a través del software Cochrane Review Manager (RevMan; version 5.3).Resultados: 6 estudios fueron incluidos, con un total de 1.862 pacientes. La probabilidad de presentar una mejoría clínica definitiva en el grupo que recibió antibioticoterapia fue menor (RR 0,5; IC95% 0,92-0,98; p= 0,004; IC2=44%). La probabilidad de presentar una recurrencia de la apendicitis en el grupo que recibió antibioticoterapia fue notablemente superior (RR 94,86; IC95% 30,73-292,81; p< 0,00001; IC2=0%). El grupo conservador presentó un menor riesgo de presentar una complicación mayor (RR 0,55; IC95% 0,36-0,85; p=0,007; IC2=0%). El tratamiento conservador presentó una duración de la estancia hospitalaria superior que la apendicectomía (MD 0,34; IC95% 0,25-0,42; p<0,00001; IC2= 64%).Conclusiones: Esta revisión sistemática demuestra que, en términos de eficacia, recurrencia del cuadro y duración de la estancia hospitalaria, la antibioticoterapia es inferior a la apendicectomía en adultos con apendicitis aguda no complicada y, superior en evitar la presencia de complicaciones mayores.

A Brief History of Blockchain Interoperability
Authors: Belchior Rafael , Süßenguth Jan , Feng Qi , Hardjono Thomas , Vasconcelos André , Correia Miguel
Published: September 2023

Blockchain interoperability conflates the need for distributed systems to communicate with third- party systems without the existence of a canonical chain or orchestration layer. As there is not “a chain to rule them all” (due to reasons such as performance, privacy, and market forces), these distributed systems rely on exchanging data and value across network boundaries. Interconnected systems achieve a higher value than the sum of their parts, similar to how the Internet emerged as a set of isolated Local Area Networks (LANs) - and, by force of surprising synergies, such networks fundamentally transformed society, forever. Concurrently, in the last decade, we have witnessed the astonishing development of blockchain technologies, which seem more connected than ever: via bridges [13, 15, 16, 31], oracles [45], and other interoperability mechanisms [4, 9, 17, 48, 89]. These recent developments have, slowly but steadily, contributed to the improvement of the scalability of blockchain networks, as well as providing new functionality and use cases [66], but there is still a long way to go until mass adoption. In this paper, we will dive into the rabbit hole of blockchain interoperability and explain why it is needed, what has been done in the last decade, and where it is going. 
A High Efficiency Non-Isolated Three-Phase Unfolding Based Electric Vehicle Powertrain
Authors: Khan Mohammad Saleh , Nag Soumya Shubhra , Das Anandarup
Published: September 2023

Three-phase unfolding based converters offer a radically different approach to two-stage dc to three-phase ac conversion, with potential benefits for electric vehicle (EV) powertrains. However, research on non-isolated three-phase un- folding particularly for EV powertrains is currently lacking. This paper presents a novel non-isolated bidirectional buck-boost three-phase unfolding system for EV powertrains. The proposed converter incorporates a non-inverting buck-boost converter and a voltage balancer circuit in the dc-dc stage. Unlike existing unfolding systems in the literature that require two dc-dc converters capable of handling full system power, the balancer in the proposed system only handles a fraction of the total power, resulting in reduced size and improved efficiency of the converter. The paper provides detailed design guidelines and presents a straightforward control strategy for the proposed converter. To evaluate its performance, a 5 kW prototype is constructed and tested with an induction motor. The experimental results demonstrate peak efficiencies exceeding 98%.

Power quality analysis of PV inverters in agrivoltaics systems applied to smart greenhouses
Authors: Rampinelli Giuliano , Marcelino Roderval , Gruber Vilson
Published: September 2023

This work is part of a research project carried out under the R&D program regulated by the National Electric Energy Agency (ANEEL) and which has developed two smart greenhouses for protected cultivation of banana and orchid seedlings. Smart greenhouses feature control and automation systems, architecture and bioclimatic strategies, and energy systems (artificial lighting system, artificial heating system, evaporative cooling system and photovoltaic system). A sensor network monitors indoor environmental variables and an automatic weather station monitors outdoor environmental variables. A computer system based on artificial intelligence is responsible for the autonomous control of the greenhouses. This paper presents the study of power quality indicators of agrivoltaic systems applied to smart greenhouses. For relative powers greater than 20%, the total harmonic distortion of current (THDA) is less than 4% and is less than 2% for relative powers greater than 60%. At nominal power, THDA is approximately 1%. The main current harmonic components are of order 2, 3, 5, 7 and 9, however, with lower values and in accordance with the limits established in technical standards. From August 2022 to July 2023, the yield final of the agrivoltaic systems of the smart greenhouses of Santa Rosa do Sul/SC and Alpestre/RS was, respectively, 1418.91 kWh/kWP and 1490.68 kWh/kWP.

Kajian Teoritis Implementasi Peer-Assessment untuk Meningkatkan Kemampuan Partisipasi Peserta Didik pada Pembelajaran Kooperatif
Authors: Adawiyah Siti Rabiatul
Published: September 2023

The curriculum currently applied in Indonesia, namely Curriculum 2013 demands that learning be directed at student-centered-learning, so that the teacher is no longer the only actor in the learning process but shifts to become a facilitator. One of the learning models that involve students actively in the learning process is the cooperative learning model. However, in its implementation it often causes problems, namely the occurrence of gaps in student participation in group work. This participation gap will lead to new problems, especially if the teacher gives the same value to all group members without considering the contribution of each student. Meanwhile, to assess the performance of each student in the group, it is not easy for the teacher to do this, especially if the number of students is quite large in one class. One solution to overcome these problems is to implement peer-assessment. This study aims to provide a theoretical study of the application of peer-assessment to increase student participation in cooperative learning. This research is a library research (library research). Researchers obtain data by conducting literature reviews from various sources such as books, journals, scientific works, as well as documents and other relevant literature.
