Authors: Subiyanto Adi
Published: May 2024

Berbagai aktivitas manusia telah menyebabkan konsentrasi gas rumah kaca (GRK) seperti CO2, CH4, dan N2O di atmosfer bumi semakin meningkat yang berdampak terhadap peningkatan suhu secara global dan telah mengarah kepada krisis iklim. Untuk menekan emisi GRK maka negara-negara yang meratifikasi Persetujuan Paris menetapkan target yang ingin dicapai sebagai Nationally Determined Contribution (NDC). Persetujuan Paris tersebut harus diintegrasikan ke dalam praktik diplomasi sebagai diplomasi iklim. Metode yang digunakan dalam penelitian ini adalah analisis deskriptif kualitatif. Data yang digunakan adalah laporan dari Intergovernmental Panel on Climate Change (IPCC) dan kontribusi Indonesia dalam dokumen NDC. Hasil penelitian menunjukkan bahwa 1) Pemanasan global telah menyebabkan krisis iklim sehingga menjadi ancaman bagi kelangsungan kehidupan; 2) Kontribusi Indonesia dalam menekan laju pemanasan global melalui NDC belum mampu mencapai target 29% dengan upaya sendiri (unconditional) atau 41% dengan bantuan dan kerja sama (conditional); dan 3) Diplomasi iklim yang diharapkan sebagai upaya untuk mengurangi krisis iklim tidak mudah untuk dilakukan. Kendala dalam melaksanakan diplomasi iklim karena setiap negara memiliki kepentingan masing-masing.

Published: May 2024

This study compared the physical fitness parameters of intellectually disabled special education vocational school students with those of inclusive high school students using the causal comparison method. Participants consisted of 22 (15 male, 7 female) from Special Education Vocational School and 25 (20 male, 5 female) inclusion students receiving inclusive education at high school. A physical fitness form was used to collect data on body mass index (BMI), standing long jump, flexibility, right-hand reaction, left-hand reaction, leg strength, back strength, right-hand grip, left-hand grip, 30 m sprint, and push-ups. The T-test was applied to data exhibiting normal distribution, while the Mann-Whitney U test was used for data not normally distributed. Among the parameters showing normal distribution, there were significant differences between the two different student groups in the standing long jump, flexibility, left-hand reaction, leg strength, and right-left hand grip strength. Although a significant difference was observed in the right-hand reaction, no significant differences were detected for the other non-normally distributed parameters of BMI, back strength, 30-m sprint, and push-ups. Our results indicated that students with intellectual disability (ID) enrolled in inclusive education at the high school level performed better in all physical fitness tests conducted compared to their peers in special education vocational schools.

Authors: Boya Bünyamin , Saracoglu İsmail
Published: May 2024

It has been reported that the academic skills of children with specific learning disabilities (SLDs) and their participation in physical activity may be affected. This study aimed to examine the relationship between physical activity level and quality of life in children with SLDs. The study was conducted with children diagnosed with SLDs at the Afyonkarahisar Special Education and Rehabilitation Center. Once the sociodemographic information of the participants was recorded, their physical activity levels were determined using the Physical Activity Questionnaire for Older Children (PAQ-C, ages 8-14 years), and their quality of life levels were assessed using the Pediatric Quality of Life Inventory (PedsQL). A total of 51 individuals, 21 girls and 30 boys, were included in the study. The mean age of the participants was 10.58±1.51 years. Physical activity score had a weak positive correlation with the physical health summary score (rspearman=0.342, p=0.014); weak positive correlations with the emotional functionality score (rspearman=0.308, p=0.028) and the school functionality score (rspearman=0.337, p=0.016); and moderate positive correlations with the school functionality score (rspearman=0.427, p=0.002), the psychosocial health summary score (rspearman=0.440, p=0.001), and the total PedsQL score (rspearman=0.462, p=0.042). In addition, the physical activity score was determined to statistically significantly predict the total PedsQL score (F=13.297; p=0.001). In conclusion, this study revealed that the physical activity levels of children with SLDs significantly affected their quality of life.

Authors: Alvurdu Sümer , Keskin Kadir , Arslan Yasin
Published: May 2024

The aim of this study is to compare the movement characteristics and heart rate (HR) response of hearing-impaired futsal players based on their playing positions during a simulated game. The study involved twelve players from the Turkish Deaf Men's Futsal National Team, and PlayerLoad (PL) metrics such as total PL (PLTOTAL), PL per minute (PL·min⁻¹), peak PL (PLPEAK), low to very high PL bands (PLLOW-PLVHIGH), and external load variables such as acceleration (ACC), deceleration (DEC), explosive efforts (EXPEFF), and right/left change of direction (COD-R, COD-L), were analyzed using inertial movement analysis (IMA). Additionally, the internal load metrics, including minimum, average, and maximum HR (HRMIN, HRAVE, HRMAX), percentage of HRMAX (%HRMAX) and percentage of time spent in different HR zones (HRZONE1 to HRZONE4) were continuously monitored. IMA variables and HR metrics, based on playing position, were analysed with the Kruskal-Wallis H test. Group comparisons were conducted using the Mann-Whitney U test, and Bonferroni correction was applied. As a result, PL variables change with notable distinctions between defenders and wingers. Additionally, the PLVHIGH stands out as the only significant difference when comparing wingers and pivots. Wingers generally exhibit different external load, including ACC and COD-L, compared to defenders. Additionally, differences were observed in COD-L between pivots and defenders, as well as in COD-R between pivots and wingers. In conclusion, external and internal load metrics during the simulated game vary depending on the players’ positions in hearing-impaired futsal players, highlighting the importance for coaches to consider this diversity in their athlete monitoring approaches.

Published: May 2024

Pentameric symmetry characterizes echinoderms and is most readily observed in sea stars. However, some pentamerous sea star individuals deviate from the normal 5-arm pattern, most likely as a result of errors in regeneration, but the frequency of these deviations and their ecological consequences for the individuals are poorly understood. Here, we report the extent of deviations from pentamery in multiple populations of co-occurring sea star species and tested 3 potential advantages of supernumerary arms—increased oral surface area, increased feeding, and faster righting response—in 1 species, the bat star Patiria miniata. Using underwater surveys and behavioural experiments at 16 sites in Barkley Sound, British Columbia, Canada, we found individuals with atypical arm numbers in 5 of 9 pentamerous sea star species. There were significant differences among sites and species, with site-specific mean percentages of atypical sea stars ranging from 0.8 to 14.6% and species-specific mean percentages ranging from 0 to 10%. Bat stars had the highest proportion of individuals with atypical numbers of arms, with site-specific frequencies ranging from 0 to 25%. The probability of feeding and righting speed were similar between bat stars with and without supernumerary arms, but bat stars with supernumerary arms had slightly larger oral surface areas for a given arm length, which could confer an advantage in adherence to the substrate. Although the advantages of supernumerary arms for bat stars appear to be negligible, the lack of any clear disadvantage suggests that selection against atypical variants might be weak, leading to limited selection on the accuracy of regeneration in this species.
Genetic connectivity and isotopic niches of alvinocaridid shrimps from chemosynthetic habitats in Aotearoa/New Zealand, with a new Alvinocaris species
Authors: Methou P , Ogawa NO , Nomaki H , Ohkouchi N , Chen C , Schnabel K
Published: May 2024

Chemosynthetic ecosystems off Aotearoa/New Zealand comprise both hydrothermal vents on the Kermadec Arc and methane seeps on the Hikurangi Margin which host rich communities of specialized fauna including 4 alvinocaridid shrimp species. The systematic positions of these New Zealand alvinocaridid shrimps have not been studied using genetic tools and little is known about their habitat use and feeding habits. Here, we re-evaluate the taxonomy of alvinocaridid shrimps from New Zealand using genetic barcoding and characterize their connectivity and isotopic niches across 8 localities. We describe a new species, Alvinocaris webberi sp. nov., previously confused with A. longirostris. We also show that A. alexander and A. chelys are junior synonyms of A. dissimilis, revealing a high genetic connectivity across hydrothermal vents and methane seeps from Japan to New Zealand, greatly extending its range. Finally, we find clear niche separation in co-occurring alvinocaridid shrimps, suggesting different diets and/or habitat use. Nevertheless, all species rely on chemosynthetic resources, regardless of the habitat depth, which ranges from 380 to 1650 m.
Transforming Foreign Language Teaching Practices through Communicative Classroom-based Assessment Programs
Authors:   , Rouffet Charline Maguy Lydie
Published: May 2024

In today's foreign language (FL) education, FL teachers universally recognize the importance of fostering students' ability to communicate in the FL. However, existing assessments often do not sufficiently evaluate this crucial aspect. Instead, assessments primarily focus on formal language knowledge in isolation, disconnected from real-world communicative contexts. This misalignment between assessment practices and communicative objectives, which is particularly prevalent in the lower form of secondary education in the Netherlands, hampers effective FL teaching.

The aim of this PhD research project was to gather insight into the potential of assessments to steer FL teaching practices. To this end, tools for developing communicative classroom-based assessment (CBA) programs were designed and implemented in practice, in close collaboration with FL teachers. The first study reported upon in this dissertation (Chapter 2) investigates which factors contribute to the identified lack of alignment between learning goals and assessment practices. The second study (Chapter 3) then shows how CBA-tools were co-designed to overcome the challenges FL teachers face when developing assessments. The third study (Chapter 4) explores how these tools were used by other FL teachers (who did not take part in the co-design process) to implement a communicative CBA program in their own context. In the final study (Chapter 5), effects of the newly designed CBA programs on teaching practices are investigated, taking both teachers’ and students’ perspectives into account. Findings reveal that assessing FL competencies in a more communicative way can transform teaching practices, placing communicative abilities at the heart of FL education.

Charline Rouffet is a foreign language teacher educator and a researcher at the University of Applied Sciences Utrecht, in collaboration with Utrecht University.
Grow old or die young

Published: May 2024

In this thesis, we explore the dynamics, T-cell receptor (TCR) diversity and functional characteristics of lymphocytes in various tissue sites in homeostasis and during imbalanced states. While natural killer cells stand out as an interesting cell type for cell therapy against cancer, researchers have questioned whether they may be too short-lived to be effective in the long term. We quantified the lifespan of natural killer cells in vivo and found it to be 94 days — longer than previously reported in the literature. Shifting our focus to T cells, particularly to memory T cells residing in tissues of wildling mice and humans, we examined the differences in their lifespan across various tissue sites compared to their counterparts in blood. Our findings challenge the current notion that tissue-resident memory T cells are long-lived. We found that tissue-resident cells in the skin, the lung and the liver are shorter-lived than those in circulation. Our studies also shed new light on the ongoing debates regarding the lifespan of regulatory T cells and suggest that during adulthood their maintenance is mostly independent of thymic output. Additionally, we investigated the impact of aging and neonatal thymectomy on the functional characteristics and TCR repertoire diversity of naive and memory T-cell populations during adulthood. Contrary to common belief, we found that the immune system of individuals who had been thymectomized at very early age did not show any signs of premature aging. Instead, their TCR repertoire was as diverse as that of age-matched individuals. These insights into the functionality, dynamics, and diversity of lymphocytes throughout the body do not only improve our understanding of the immune system in health and disease, but also pave the way for the development of novel therapeutic approaches.
Metal Synergy in Pd-Ni Bimetallics
Authors:   , Zand Florian
Published: May 2024

This thesis aims to enhance our understanding of metal segregation in supported bimetallic catalysts, to maximize the synergy between metals. It covers the assessment, effects, and origin of metal segregation as exemplified by supported alloyed Pd-Ni nanoparticles.
To assess the degree and type of metal segregation in detail, we introduce a novel analytical technique to study industrial mesoporous catalysts – atom probe tomography (APT). Due to its nature, measuring mesoporous catalysts was not yet possible with APT, thus we have developed a resin-based sample preparation approach. This enables to unravel sub-nm compositional heterogeneities within/between nanoparticles, which is crucial for the optimization of industrial catalysts.
With this upgraded arsenal of analytical techniques, we investigated the origins and effects of metal segregation for bimetallic catalysts prepared via industrially relevant incipient wetness impregnation. It spans most of the catalyst’s lifetime from precursor decomposition during calcination, alloy formation during reduction, and restructuring under steady and modulating operating conditions. Hereby, we elucidate the pathways for alloy formation for less uniform catalyst materials, describe the origin of reduction promotion, and showcase the catalyst’s state under operando conditions.
However, next to revealing pathways which lead to alloy formation, we shed light on the origins leading to metal segregation. Therefore, we followed the metal precursor decomposition using different gas atmospheres. This allowed to assess the degree of metal segregation and pinpointed which role the decomposition of precursors plays.
Finally, we elucidated how metal segregation/alloying between Pd and Ni affects catalysis mechanistically for both CO2 hydrogenation and chitosan depolymerization.

Varieties of Anxieties: Disaggregating Emotion and Voting Behavior in the COVID-19 Era
Authors: Lall Ranjit , Vilalta David
Published: May 2024

How does anxiety influence voting behavior? Whereas anxiety is usually treated as a unidimensional emotion, we highlight the multiplicity of socially contingent forms it can assume in response to societal threats. Different anxieties, we posit, can create distinct axes of political competition along which anxious voters exhibit widely varying preferences. We illustrate our argument with unique observational and experimental survey data from Spain’s COVID-19 crisis, showing that individuals anxious about the pandemic’s health consequences favored parties advocating stringent lockdown restrictions, whereas individuals anxious about its economic disruption preferred parties opposing such measures. Analyzing municipality-level results from Madrid’s 2021 regional election, we additionally provide evidence that COVID-19 boosted support for pro-lockdown parties in areas more exposed to its health effects and support for anti-lockdown parties in areas more exposed to its economic impact. Our findings point to the importance of disaggregating complex emotional states for understanding the determinants of voting behavior.
Історія вишивки за часів правління Єлизавети I (1533-1603 рр.)
Authors: Луканець Валерія
Published: May 2024

Історія вишивки за часів правління Єлизавети I є майже недослідженою темою в українській історіографії. Стаття дає можливість дізнатися про певні аспекти з вказаної теми та разом з тим дозволяє подивитися на історію Англії XVI ст. з нового боку, у такий спосіб розширити власне розуміння тогочасного англійського суспільства. Зокрема, у дослідженні висвітлюється інформація про види та техніки вишивки, що були популярними в єлизаветинську епоху. Визначається вплив розвитку англійських садів на розвиток вишивки. Дається короткий огляд джерел, які надихали на створення вишивки. А також досліджується професія вишивальниці та різниця між професійною і домашньою вишивкою. Розкриваються особливості єлизаветинської вишивки, в якій переважає національний і світський характер.
«Ведмежа послуга своїй нації»: пропаганда проти створення дивізії Ваффен-СС «Галичина» (травень-червень 1943 року)
Authors: Хом’як Оксана
Published: May 2024

У статті проаналізовано риторику ключових противників створення дивізії Ваффен-СС «Галичина» на початковому етапі кампанії рекрутування у травні-червні 1943 р. Окремо висвітлено поширення чуток і спроби протидіяти їм.
У статті з’ясовано, що риторика польської пропаганди щодо українського питання зумовлювалася бажанням залучити українців до здійснення власних цілей, уявним образом повоєнної Польщі та польсько-радянських відносин. Показано, що залучення українців до німецької дивізії польське підпілля розглядало як свідчення політичної недалекоглядності. Зроблено акцент на формуванні негативного образу добровольців як неосвічених селян, яких рекрутували за допомогою примусових методів. Іншим засобом контрпропаганди стали різноманітні чутки про «гарматне м’ясо», «інший спосіб вивезти в Німеччину» тощо, які на думку УЦК, поширювалися саме польською стороною. Аналіз документів УЦК та українського руху Опору показав повне несприйняття політичних поглядів і методів діяльності один одного. Попри те, що офіційно ОУН(б) засудила ідею служби українців у німецьких військових формаціях і пропонувала власну альтернативу – поповнювати ряди українського підпілля, провідники на місцях часто керувалися власними міркуваннями, зазвичай не протидіяли і/або наказували/заохочували вступати до дивізії в час, коли створення УПА тільки розпочиналося в Галичині.
Важко сказати, наскільки ефективною була контрпропаганда в період «дивізійної ейфорії» травня-червня 1943 р. Втім, дані звіту ВУ від 30 жовтня 1943 р. дозволяють побачити, що з 19 047 осіб, які отримали виклик на військове навчання, тільки 11 578 осіб таки розпочали свій вишкіл. Це дозволяє припустити, що в умовах зміни загального контексту й індивідуальних обставин дискусія та сумніви щодо зробленого раніше вибору таки були.
«Утопічний» аспект «загальноруської» історії: рецепція М. Гоголя
Authors: Бандура Юрій
Published: May 2024

У 1852 р. в Москві помер Микола Гоголь, однак його творча спадщина продовжує жити у текстах, таких, як «Тарас Бульба», «Ніс», «Шинель», «Ревізор», «Мертві душі» й ін. Фактично відтоді і дотепер національна ідентичність М. Гоголя, його культурно-мистецький вплив на майбутні покоління, який годі переоцінити, досі видаються наріжним каменем української та російської історіографії, враховуючи, що поза літературознавством роль Гоголя як інтелектуала та християнського мислителя привертає дедалі більшу увагу. Так, попри рефлексії над викликами сучасності, письменник, з одного боку, послідовно реагував на націєтворчі процеси у межах Російської імперії, з іншого – зважав на суспільне життя провідних європейських країн. Відповідно, однією з таких Гоголевих рефлексій, врешті-решт, став осмислений імперіальний образ Русі як національної ідеї та культурного міфу, що досліджувався та формувався у період загальнослов’янського романтизму першої половини ХІХ ст. У зв’язку з цим у статті розглянуто історіософську концепція «загальноруської» історії М. Гоголя з погляду утопічних і темпоральних проекцій на українське минуле і з української перспективи.

Стаття присвячена аналізу спогадів Миколи Галагана в якості джерела з історії дипломатичної місії УНР в Румунії та Угорщині у 1918-1920 рр. Увага звертається на особистісний контекст формування мемуарних свідчень, з’ясовується ступінь їх об’єктивності, важливість наведеного фактичного матеріалу, корисність цієї інформації для відображення державотворчих процесів доби Української революції.
Наголошено, що активне залучення спогадів сприятиме формуванню доволі об’єктивної картини перебігу історичних подій, активізуватиме вивчення державотворчих процесів початку ХХ ст. вітчизняною історіографією.
Від аури твору до уявного музею: проблема копії та оригіналу твору мистецтва
Authors: Качковська Яна
Published: May 2024

У статті проаналізовано поняття аура твору мистецтва, запропоноване Вальтером Беньяміном. Авторка з’ясовує подальший розвиток цього терміну, зокрема у працях Андре Мальро, Адама Лоу та Бруно Латура. Важливими для розуміння концепції стають терміни копія та оригінал твору. Бруно Латур та Адам Лоу розглядають копію не як похідне від оригіналу, що лише фрагментарно зберігає значення і роль, а як плідну територію для новацій. Зрештою, зроблено висновок про зв’язок концепції аури твору мистецтва, уявного та цифрового музеїв.
Pensamento Algébrico no 5° ano do Ensino Fundamental
Authors: Felix Marques Anailde , Ramos de Almeida Jadilson
Published: May 2024

Este artigo tem por objetivo caracterizar o pensamento algébrico revelado por estudantes do 5° ano ao resolverem uma tarefa de valor omisso. Na literatura não existe um consenso sobre o pensar algebricamente porém existem três perspectivas distintas, tal como especificam Almeida e Câmara. Em sintonia optamos pela mais contemporânea, a Teoria da Objetivação, alinhando-a à nova argumentação apresentada na Base Nacional Comum Curricular. Nesta perspectiva, existem três elementos interligados que caracteriza esse pensamento algébrico: a indeterminação, denotação e a analiticidade. Para o desenvolvimento da pesquisa recorremos aos aspectos metodológicos da atividade de ensino-aprendizagem a partir da Teoria da Objetivação e a análise multimodal descrita por Arzarello. Propomos uma tarefa de valor omisso contendo seis problemas com grau de dificuldade crescente a duas estudantes do 5° ano do Ensino Fundamental. Todo o nosso material para análise foi desenvolvido por elas na atividade de ensino-aprendizagem recorrendo aos distintos recursos semióticos para representar as discussões. Portanto, foi fundamental gravar todas as interações com o auxílio de aparelhos eletrônicos. Por fim, fizemos uso da análise multimodal de modo a nos debruçarmos sobre os vídeos, áudios e registros escritos realizados, identificando que as estudantes pensaram algebricamente diante da tarefa proposta.
abordagem da temática Educação Financeira em alguns Livros Didáticos do Novo Ensino Médio
Authors: Régis de Almeida Wálmisson , Souza Alice Amaral , Nazário Rafaela da Silva , Abi-Acl Renato Scalon
Published: May 2024

Este trabalho teve por objetivo investigar a existência de abordagens contextualizadas dos temas da Matemática Financeira sob a ótica da Educação Financeira em algumas obras do Novo Ensino Médio. Para sua execução, foi realizada uma pesquisa de natureza qualitativa através da análise bibliográfica de alguns dos materiais didáticos desse segmento, ofertados pela rede pública de ensino estadual de Minas Gerais, com o intuito de identificar se e como os temas envolvendo Educação Financeira são abordados nestas coleções. Para esse propósito, foram analisadas cinco coleções de Matemática e suas Tecnologias, além do livro escolhido pela escola de atuação de um dos pesquisadores, envolvendo três editoras diferentes, todas disponibilizadas pelo Programa Nacional do Livro e do Material Didático - PNLD. Esses livros fazem parte do material didático oferecido pelo estado de Minas Gerais para a implantação do Novo Ensino Médio. Foi possível observar com este trabalho que os materiais analisados apresentam a temática: ainda que algumas obras mantenham uma abordagem descontextualizada, afastada do cotidiano dos alunos, com foco em repetições de cálculos que podem carecer de sentido prático, outros materiais apresentam discussões mais amplas e voltadas ao desenvolvimento de uma Educação Financeira na prática, apresentando assim uma possibilidade maior de desenvolvimento do pensamento crítico no que se refere a tomadas de decisão da vida financeira dos discentes.

Basophils are the least common granulocytes, accounting for <1% of peripheral blood leukocytes. In the last 20 years, analytical tools for mouse basophils have been developed, and we now recognize that basophils play critical roles in various immune reactions, including the development of allergic inflammation and protective immunity against parasites. Moreover, the combined use of flow cytometric analyses and knockout mice has uncovered several progenitor cells committed to basophils in mice. Recently, advancements in single-cell RNA sequencing (scRNA-seq) technologies have challenged the classical view of the differentiation of various hematopoietic cell lineages. This is also true for basophil differentiation, and studies using scRNA-seq analysis have provided novel insights into basophil differentiation, including the association of basophil differentiation with that of erythrocyte/megakaryocyte and the discovery of novel basophil progenitor cells in the mouse bone marrow. In this review, we summarize the recent findings of basophil ontogeny in both mice and humans, mainly focusing on studies using scRNA-seq analyses.

This study proposes and analyzes a deterministic mathematical model to describe the dynamics of corruption transmission. We began by proving that the solution to the model is bounded and positive. The next-generation matrix approach is used to compute the basic reproduction number (R0) in relation to corruption-free equilibrium. The Jacobian and Lyapunov functions are used to show that corruption-free equilibrium is asymptotically stable in both locally and globally when R0<1, and otherwise, an endemic corruption equilibrium develops. Furthermore, the sensitivity of the model's parameters was investigated. The findings demonstrate that religious precepts govern public education. The two sectors most susceptible to corruption control are education and corrections. The study recommends investing more in the provision of public education to citizens by creating awareness among all and including it in the education curriculum and religious leaders to teach their followers seriously about the impact of corruption as well as the use of jail as punishment. The numerical simulation results agreed with the analytical results.

Low back pain (LBP) is one of the most prevalent and disabling disease worldwide. However, the specific biomechanical changes due to LBP are still controversial. The purpose of this study was to estimate the lumbar and lower limb kinematics, lumbar moments and loads, muscle forces and activation during walking in healthy adults and LBP. A total of 18 healthy controls and 19 patients with chronic LBP were tested for walking at a comfortable speed. The kinematic and dynamic data of the subjects were collected by 3D motion capture system and force plates respectively, and then the motion simulation was performed by OpenSim. The OpenSim musculoskeletal model was used to calculate lumbar, hip, knee and ankle joint angle variations, lumbar moments and loads, muscle forces and activation of eight major lumbar muscles. In our results, significant lower lumbar axial rotation angle, lumbar flexion/extension and axial rotation moments, as well as the muscle forces of the four muscles and muscle activation of two muscles were found in patients with LBP than those of the healthy controls (p < 0.05). This study may help providing theoretical support for the evaluation and rehabilitation treatment intervention of patients with LBP.

The structural performance of critical infrastructure during extreme events requires testing to understand the complex dynamics. Shake table testing of buildings to evaluate structural integrity is expensive and requires special facilities that can allow for the construction of large-scale test specimens. An attractive alternative is a cyber-physical testing technique known as Real-Time Hybrid Simulation (RTHS), where a large-scale structure is decomposed into physical and numerical substructures. A transfer system creates the interface between physical and numerical substructures. The challenge occurs when using multiple actuators connected with a coupler (i.e., transfer system) to create translation and rotation at the interface. Tracking control strategies aim to reduce time delay errors to create the desired displacements that account for the complex dynamics. This paper proposes two adaptive control methodologies for multi-axial real-time hybrid simulations that improve capabilities for a higher degree of coupling, boundary, complexity, and noise reduction. One control method integrates the feedback proportional derivative integrator (PID) control with a conditional adaptive time series (CATS) compensation and inverse decoupler. The second proposed control method is based on a coupled Model Predictive Control (MPC) with the CATS compensation. The performance of the proposed methods is evaluated using the virtual multi-axial benchmark control problem consisting of a steel frame as the experimental substructure. The transfer system consists of a coupler that connects two hydraulic actuators generating the translation and rotation acting at the joint. Through sensitivity analysis, parameters were tuned for the decoupler components, CATS compensation, and the control design for PID, LQG, and MPC. Comparative results among different control methods are evaluated based on performance criteria, including critical factors such as reduction in the time delay of bothactuators. The research findings in this paper improve the tracking control systems for the multi-axial RTHS of building structures subjected to earthquake loading. It provides insight into the robustness of the proposed tracking control methods in addressing uncertainty and improves the understanding of multiple output controllers that could be used in future cyber-physical testing of civil infrastructure subjected to natural hazards.
Bayesian maximum entropy interpolation analysis for rapid assessment of seismic intensity using station and ground motion prediction equations
Authors: Kang Dengjie , Chen Wenkai , Jia Yijiao
Published: May 2024

In this paper, we explored the combination of seismic station data and ground motion prediction equations (GMPE) to predict seismic intensity results by using Bayesian Maximum Entropy (BME) method. The results indicate that: 1) In earthquake analysis in Japan, soft data has predicted higher values of intensity in disaster areas. BME corrected this phenomenon, especially near the epicenter. Meanwhile, for earthquakes in the United States, BME corrected the erroneous prediction of rupture direction using soft data. 2) Compared with other spatial interpolation methods, the profile results of Japan earthquake and Turkey earthquake show that BME is more consistent with ShakeMap results than IDW and Kriging. Moreover, IDW has a low intensity anomaly zone. 3) The BME method overcomes the phenomenon that the strength evaluation results do not match the actual failure situation when the moment magnitude is small. It more accurately delineates the scope of the disaster area and enriches the post-earthquake processing of disaster area information and data. BME has a wide range of applicability, and it can still be effectively used for interpolation analysis when there is only soft data or few sites with data available.
Reservoir characteristics analysis and favorable area prediction of Zhuhai Formation, Wenchang A oilfield, South China Sea
Authors: Liu Jianning
Published: May 2024

Wenchang A oilfield is a recently discovered low-permeability oilfield in the western South China Sea. The exploration target is the Zhuhai Formation, which reservoir lithology changes significantly, and the distribution of favorable reservoirs is unclear. In this study, the reservoir characteristics of the Zhuhai Formation in the Wenchang A oilfield, South China Sea, were analyzed through core identification, thin section identification, physical property testing, pre-stack geostatistical inversion, and frequency-based AVO inversion. Pre-stack geostatistical inversion is based on geostatistics and combines the seismic inversion algorithm with the stochastic sequential simulation algorithm. While the frequency-varying AVO inversion method is an extension of the conventional AVO inversion method, with its core technology being spectrum decomposition. After frequency division, multiple data sets directly participate in the calculation, which enhances the stability and accuracy of inversion.We also predict the favorable reservoir areas of six small layers in the Zhuhai Formation. The results show that 1) the reservoir lithology of the Zhuhai Formation mainly consists of feldspar quartz sandstone and feldspar quartz sandstone, indicating high compositional maturity. The porosity of the reservoir ranges from 14.0% to 19.0%, with an average value of 16.3%. The permeability of the reservoir ranges from 3.1 mD to 126.1 mD, with an average value of 22.4 mD, indicating a medium porosity and low permeability reservoir. The supporting structure of a sandstone reservoir is particle-supported, with the main contact being the “point-line” contact between particles. The main types of pores in sandstone are primary intergranular pores and secondary intergranular dissolved pores. Some pores are feldspar-dissolved pores, and occasionally there are hetero-based micropore. 2) The diagenesis of the Zhuhai Formation reservoir mainly includes compaction, cementation, and dissolution. Cementation and dissolution have minimal impact on the physical properties of reservoirs. The porosity loss of the reservoir after compaction ranges between 16.0% and 27.9%, and the compaction rate ranges between 40.0% and 69.8%, indicating a medium compaction diagenetic facies. 3) The favorable areas of each layer of the Zhuhai Formation are mainly concentrated in the southwest of the study area. The upper layer of ZH1I, the upper layer of ZH1II and the lower layer of ZH1II exhibit the best physical properties, the thickest favorable sand body, the strongest oil and gas display, the widest range of favorable areas, and the greatest exploration potential. The favorable exploration potential of layer 1 in the lower part of ZH1I and layer 2 in the upper part of ZH1II is moderate. The second layer in the lower part of ZH1II has the poorest properties and lower exploration potential. The main factors affecting the favorable area include physical properties, oil and gas display, sand body thickness, etc.
