Research on optimal path planning technology for industrial robots based on improved IDE algorithm
Authors: Zuo Peiliang
Published: October 2024

Realizing efficient and accurate positional movement of industrial robots is one of the key technologies to accelerate industrial development. In this paper, a four-wheel-drive McNamee mobile robot is selected as the research object, and the improved IPSO-IDE algorithm is proposed, which is combined with a PID controller to realize the accurate positioning and optimal path planning of industrial machines. The experimental results of robot kinematic parameter calibration show that the distance error of the robot calibrated with the algorithm is greatly reduced, and not only that, the IPSO-IDE algorithm reduces the average distance error of the robot to only 0.124 mm, which is much smaller than that of the PSO algorithm and the DE algorithm. The IPSO-IDE algorithm is capable of planning the optimal motion path in a short time, as demonstrated by the results of robot map environment simulation experiments. In the simulated map environment of 10 m × 10 m, the convergence speed of the algorithm’s planning path is 12.69 seconds, and the generated optimal path length is 15.0221 m, which is better than other algorithms. In conclusion, the proposed IPSO-IDE algorithm has an excellent performance in terms of path-planning capabilities for industrial robots.

Published: October 2024

ABO group testing is critical for allogeneic stem cell transplantation because mismatches can cause both transfusion and engraftment challenges. Even with ABO-matched donor-recipient pairs, ABO group determination may provide valuable insight into allograft status. Herein, we report a case of a 76-year-old female patient with myeloid neoplasm who underwent ABO-matched stem cell transplantation and in whom mixed-field ABO antigen expression during routine follow-up testing post-transplantation was the first sign of a change in transplant graft status; the mixed-field findings pre-dated changes in formal chimerism testing. This case underscores the potential of mixed-field ABO typing as an early indicator of disease recurrence in ABO-matched stem cell transplants and suggests that, in such cases, more sensitive forms of chimerism testing and/or closer monitoring for disease recurrence, particularly in the clinical setting of myeloid neoplasms, may be warranted.

Authors: Keller Margaret A. , Nance Sandra T. , Maurer Joan , Kavitsky Victoria , Babariya Shraddha P.
Published: October 2024

Rare donor programs are critically important for those patients with rare phenotypes who have produced the associated alloantibodies that necessitate the provision of rare blood components. We describe the American Rare Donor Program (ARDP) and its establishment, members, and policies. The specific phenotypes meeting the ARDP criteria for inclusion are described. Data on the number of rare donors registered by year, and the number of requests for rare blood components received and fulfilled over the 25 years of the program (1998–2023) are provided, along with a description of some notable cases and discussion of how the program supports patients with sickle cell disease.
Implementation of EU Acts in the Czech Parliament: A Slow and Laborious Quest with an Uncertain Outcome
Authors: Říha Michal
Published: October 2024

The article focuses on the statutory implementation practice of EU legislation in the Czech Republic based on statistical evidence. The main focus is a comparison of the length of the legislative procedure in the Parliament from 2010–2021, i.e. three election periods of the Chamber of Deputies, which is the dominant body of law-making in the Czech Republic. In conclusion, the author describes an unusually lengthy implementation process and analyses possible reasons for one of the worst transposition-on-time results within the EU. However, he refutes the claim that the transposition deficit is mostly caused by the Parliament.

The need for cosmetic products is increasingly developing over time, making cosmetics a primary necessity. One of the most widely used cosmetic products in Indonesia is Wardah. This study aims to test and explain the role of brand equity in mediating the influence of country of origin on repurchase intention among Wardah beauty cosmetic consumers in Denpasar City. The sample in this study was 130 respondents. Data was collected through a questionnaire. The collected data was analyzed using classical assumption tests, path analysis, and mediation role tests. The results of this study show that country of origin has a positive and significant effect on repurchase intention, country of origin has a positive and significant effect on brand equity, brand equity has a positive and significant effect on repurchase intention, and brand equity is able to partially mediate (complementary partial mediation) the effect of country of origin on repurchase intention among Wardah beauty cosmetic consumers in Denpasar City. The theoretical implications of the findings of this study support consumer behavior theory. Practical implications if consumer perception of the country of origin of Wardah brand products is good, then brand equity will be good, which can increase repurchase intention.
Pentingnya Respon Komplit Patologi Paska Kemoterapi Neoadjuvan pada Penanganan Kasus Kanker Payudara Stadium Awal
Authors: Adiputra Putu Anda Tusta
Published: October 2024

Saat ini kemoterapi neoajuvan (Neoadjuvant Chemotherapy/NAC) semakin banyak digunakan sebagai lini pertama untuk penanganan kanker payudara lokal yang berisiko tinggi. Kemoterapi neoajuvan untuk kanker payudara adalah pilihan terapi yang ditetapkan untuk kanker payudara berisiko tinggi, kanker payudara lokal dengan stadium lanjut, kanker payudara yang tidak dapat dioperasi, atau untuk meningkatkan peluang dilakukannya operasi konservasi payudara (Breast Conserving Surgery). Selain NAC, ada kemoterapi ajuvan yang ditujukan untuk mengatasi mikrometastasis yang tidak terlihat, sehingga mengurangi resiko kekambuhan lokal maupun sistemik. Pencapaian respon komplit patologi terkait dengan kelangsungan hidup jangka panjang dan oleh karena itu FDA merekomendasikannya sebagai titik akhir utama dalam uji coba NAC dengan harapan dapat meningkatkan angka kelangsungan hidup pada pasien dengan kanker payudara. Target respon komplit patologi dapat dipertimbangkan pada pasien dengan subtipe kanker payudara agresif yang memiliki respon baik sebelum dilakukan operasi.

Authors: Lima Évelyn Cristina Morais Pessôa , Souza Claudinalle Farias Queiroz de , Costa Aurélio Molina da , César Raissa Catarina Vergueiro , Aquino Jael Maria de
Published: October 2024

Objective: To identify validated instruments for assessing user satisfaction with nursing teleconsultations in reproductive and sexual health.
 
Theoretical Framework: Nursing teleconsultations in the field of reproductive and sexual health are already a reality. In this context, it is necessary to identify the satisfaction level of people assisted by such services to ensure the need for investments and implementations in healthcare services.
 
Method: This is an integrative literature review based on the PRISMA methodology. The article search was conducted in the PubMED and LILACs databases and the Web of Science library. Inclusion criteria were original articles published in the last five years, in Portuguese, English, and Spanish. Duplicate articles were excluded.
 
Results and Discussion: Two articles were identified that present satisfaction instruments for nursing teleconsultations in Reproductive and Sexual Health, both indexed in PUBMED. In addition to these, nine other articles present quantitative and qualitative processes for evaluating nursing teleconsultations. None of the instruments found were validated.
 
Research Implications: A lack of validated instruments for assessing user satisfaction in nursing teleconsultations in general, including in RSH (Reproductive and Sexual Health), was identified.
 
Originality/Value: This study contributes to the evidence of the need to develop validated instruments capable of diagnosing user satisfaction with nursing teleconsultations. Without such rigorous assessment, it is imprecise to collect satisfaction data that supports the use of technologies such as nursing teleconsultations.

Procesy depopulacji na obszarach wiejskich województwa świętokrzyskiego w latach 2002–2021
Authors: Kopacz‑Wyrwał Iwona
Published: October 2024

Celem opracowania była analiza przestrzennego zróżnicowania procesów depopulacji na obszarach wiejskich województwa świętokrzyskiego w latach 2002–2021. Główną uwagę zwrócono na określenie skali, zasięgu i czynników mających wpływ na ubytek liczby ludności, co umożliwiło wyodrębnienie wiejskich obszarów depopulacji w województwie świętokrzyskim. Badaniem objęto wszystkie gminy wiejskie oraz część wiejską w gminach miejsko‑wiejskich. Do przedstawienia zmian w odniesieniu do procesów depopulacji wykorzystano m.in. wskaźnik dynamiki. Przeprowadzona analiza wykazała, że wyludnianie się obszarów wiejskich województwa świętokrzyskiego jest wynikiem oddziaływania wielu czynników i wykazuje znaczne zróżnicowanie przestrzenne. Ogólnie ujmując, należy stwierdzić, iż najniższym wskaźnikiem dynamiki liczby ludności charakteryzowały się gminy położone z dala od dużych ośrodków miejskich oraz te, o dominujących funkcjach rolniczych. Ponadto, odznaczały się one peryferyjnością administracyjną – były położone wzdłuż granic wojewódzkich i powiatowych. Analiza wykazała również, że przyczyny wyludniania się tych obszarów miały charakter społeczny i związane były z odpływem przede wszystkim ludności młodej i dobrze wykształconej (wśród niej dominowały głównie kobiety), niskim przyrostem naturalnym – co w konsekwencji prowadzi do starzenia się ludności.
Rozwój klubów sportowych i infrastruktury sportowej w obszarze miasta, na przykładzie piłki nożnej w Krakowie w ujęciu przestrzennym
Authors: Dyląg Kamil
Published: October 2024

Piłka nożna postrzegana jest jako ważny elementem życia społecznego i kulturowego Krakowa. Wynika to z długoletnich tradycji związanych z tą dyscypliną sportu, które są zakorzenione w dziejach miasta. Początkowo piłka nożna w Krakowie miała wymiar amatorski. Pierwsze wzmianki o bardziej zorganizowanej formie uprawiania tej formy sportu wywodzą się jeszcze z czasów pod zaborami. Po odzyskaniu niepodległości, futbol zaczął ewoluować, co wiązało się z profesjonalizacją działalności sportowej klubów. Działacze klubowi z Krakowa byli ważnymi postaciami w kierunkowaniu rozwoju piłki nożnej oraz infrastruktury sportowej, nie tylko w mieście, ale w całym kraju. W okresie dwudziestolecia międzywojennego, występowało zjawisko rozwoju demograficznego, kulturowego i gospodarczego miasta, co przełożyło się na dynamiczny rozwój sportu w tamtym czasie. W drugiej połowie XX w. nowy ustrój polityczny w Polsce, spowodował reorganizację zarządzania sportem w kraju. Ówczesne zmiany, przełożyły się na obraz funkcjonowania sportu, między innymi działalność klubowa została mocno uzależniona od zakładów przemysłowych. Po okresie transformacji związanej z przemianami ustrojowymi po 1989 roku funkcjonalność wielu klubów (zwłaszcza wielosekcyjnych), stała się znacznie trudniejsza przez odcięcie środków finansowych płynących z państwowych zakładów. Dzisiejsza sytuacja uległa zmianie, między innymi poprzez poprawę sytuacji ekonomicznej w mieście, a także partycypację Polski we wspólnocie Unii Europejskiej. Możliwość pozyskiwania środków z Unii, na rzecz rozwoju regionalnego pozwala na znacznie więcej opcji w zakresie inwestycji związanych ze sportem. Ważnym elementem rozwoju futbolu zawodowego, stał się sponsoring klubowy. Za dobry przykład udanego sponsoringu przytoczyć można dwa najbardziej utytułowane krakowskie kluby – Wisłę Kraków i Cracovię. Oba zespoły zyskały przede wszystkim stabilizację finansową oraz progres w osiąganych wynikach sportowych.

The identification of the processes and their regional problems gave guidelines for the weighting of each of them and define their criteria for the optimal growth of the plant. The study was carried out with the assignment of weights to the variables of altitude, temperature, precipitation, slopes and edaphology according to research on their degree of influence and dependence among them; the result is the areas with the greatest agricultural suitability for the cultivation of corn in the State of Mexico (with restriction of protected natural areas and urban areas), with a timely verification of the already existing crops and improve decision making by expanding the territory with the greatest probability of optimization and crops’ yield. This methodology proposal is intended to be replicable to other crops and/or areas in which the processes and patterns that modify the characteristics of areas from a crop to high yield are recognized.
Environmental diagnostic of municipality of zinacantepec, Estado de México
Authors: Bernal Lima Ariel
Published: October 2024

In the period 2021‑ 2023, technical tours were conducted as part of the Local Ecological Management of Zinacantepec to carry out the environmental diagnosis of the territory, in which soil degradation is present in the sub‑ b asin of the Tejalpa River while the forest ecosystem in the Zinacantépetl Formation is in a process of feedback according to the General System Theory (GST), that is, recovery with a positive trend in the forest cover. The purpose of this research is to analyze the characteristics of the physical‑ g eographical subsystemin order to determine the environmental conditions in the study area. In order to achieve the specific objectives, a methodology based on the evaluation of the disturbances in the balance of the environmental system was proposed, for which thematic cartography was obtained, as well as the state of evolution of the relief by means of matrices applied in field work. On the other hand, through COMPROBIDES, training sessions and working groups have been held to present multidisciplinary proposals that promote environmental protection based on the results obtained, in which processes of land use change, water erosion, deforestation, greenhouse gas emissions, water pollution and urban location in agricultural areas have been identified. It should be noted that knowledge of the geodynamics of geographic space has contributed to social and public participation for the preservation of natural resources.
Local Perception of Traditional and Avocado Crops as Ecosystem Services in the Mariposa Monarch Biosphere Reserve
Authors: Flores‑Arteaga Luis Alfonso , Rodríguez‑Soto Clarita , Galeana Pizaña José Mauricio , Gybram Pantoja Canchola Yered
Published: October 2024

The concept of ecosystem services (ES) refers to the goods and services that ecosystems produce for the benefit of people, serving as generators of well‑being. Three dimensions are recognized that promote the presence of these services: the material, the relational,and the subjective. These dimensions are highly influenced by the lifeworld, which has been crucial for documenting processes of environmental degradation. In this sense, it is important for geography to determine the connections between the socialtypifications of meaning and the spatiotemporal rhythms of action, contributing to the discovery of underlying structures of intentionality. One of the main challenges in the management of ES is their interdependence, as their relationships are often nonlinear,and there is a preference for the immediate provision of one service over others, resulting in trade‑offs characterized by the reduction of productive capacity in favor of another. This study analyzed, through semi‑structured surveys applied in the field, face to face, the perception that people living in the Monarch Butterfly Biosphere Reserve have regarding traditional and avocado crops, the latter characterized by promoting compensations through land use change from native forests to large monoculture areas in the State of Michoacán, which is rapidly expanding in the lower zone of the RBMM. The results show that perceptions and feelings associated with these services contrast with each other, daily life activities, means of family livelihood, and proximity to the core and buffer zone are determining factors in the perception of these ES. The results of this work, based on the geography of perception, can be useful as guiding threads for the development of effective, specific, and inclusive management and conservation plans based on the feelings, knowledge, and needs of people who are recognized as actors favoring ecosystem conservation or the creation of externalities.

СОЦІАЛЬНО-ПЕДАГОГІЧНИЙ ПРОСТІР РОЗВИТКУ ДИТИНИ В СУЧАСНИХ ЗАКЛАДАХ ПОЗАШКІЛЬНОЇ ОСВІТИ
Authors: Пустовіт Григорій
Published: October 2024

У статті проаналізовано теоретико-прикладні засади створення соціально-педагогічного простору розвитку дитини в сучасних закладах позашкільної освіти. Доведено, що ці заклади мають всі необхідні умови ефективної освіти, виховання, розвитку і соціалізації дітей різного віку. У контексті цих процесів актуалізовано роль демократичних і гуманістичних засад організації соціально-педагогічного простору розвитку дитини як відкритої виховної системи. Наголошено на необхідності розв’язання проблеми об’єднання зусиль усіх соціальних інститутів у площині, де розвиток дітей здійснюється не стільки в інтелектуально-знаннєвому контексті, хоча це незаперечно важливо, а більше у психолого-педагогічному й соціально-педагогічному. Доведено, що сучасна позашкільна освіта має розглядатись як така, що виявляє найближчі перспективи розвитку зростаючої особистості саме у просторі її соціального життя у закладах позашкільної освіти, а тому вони мають стати центрами мотиваційного розвитку дітей, самореалізації їхніх уявлень про себе “Я-майбутнього”.

Published: October 2024

Background. Children with cancer have a higher morbidity and mortality due to COVID-19. Vaccination of children with cancer is important. In this study, we aimed to investigate the effectiveness and side effects of the COVID-19 vaccines in children and adolescents with cancer.
Methods. Fifty-eight patients from four centers were included in the study. Antibodies to the SARS-CoV-2 spike protein levels were measured. Vaccine-related complaints were recorded.
Results. There were 33 male and 25 female patients. The mean age was 16.9±2.3 years. In 58.6% of cases, the diagnosis was hematological malignancies. Twenty patients were currently under treatment, while 38 had completed the treatment. Forty-eight patients received chemotherapy ± radiotherapy, 13 received immunotherapy, and 3 underwent stem cell transplantation. CoronoVac© and BNT162b2© vaccines were administered in 24% and 76%, respectively. The mean antibody level was lower in patients who received CoronaVac© than that of BNT162b2©, although the difference was not significant. The levels were within the protective limits in both groups. No significant difference was found in antibody levels according to diagnostic subgroups, treatment status, type of treatment, line of treatment, disease status and time between vaccines and measurement of antibody level. The most common side effects were pain at the injection site (37.9%) and malaise/weakness (17.2%), which were similar for both vaccines.
Conclusions. Our study showed that both mRNA and inactivated vaccines elicit an immune response in children with cancer. However, the seroconversion rate is significantly higher in mRNA vaccines. Side effects were similar to those seen in healthy children.

Han-Nationalism Throughout the Ages
Authors: Wu Weiying
Published: October 2024

Beginning in the 1980s, a trend of traditional studies known as “guo xue,” (国学) meaning national studies, proliferated in the wake of socioeconomic changes in China. In particular, it encompassed the revival of Confucianism, giving rise to related activity such as the establishment of “national studies institutes” (国学院) and “Han study centers”. Yet despite its popularity, the legitimacy of “national studies” came under the critical scrutiny of historians who argue that that contemporary “national studies” have either consciously or subconsciously co-opted Han traditions and practices over other ethnic cultures that made up the social fabric of past and present China, thus reinforcing the idea of “Chinese-ness” as a Han-centric and exclusionary one. This article contextualizes the discursive terrain in which Han-centricity in national studies has been conceptualized and incubated, and seeks to add nuance to the conventional wisdom, official narratives and assumptions that have guided popular discourse on present-day Chinese nationalism, ethnic policies and challenges.

Attempted Book Bans: The Censorship of Queer Themes in the 1950s
Authors: Quintana-Rodriguez Maria J.
Published: October 2024

This article aims to explore queer book banning during the 1950s in response to Cold War national defense tactics. The decade witnessed the formation of the first public LGBTQ+ rights organizations in the United States as well as a rise in queer literature and publications. This publicization of queerness in society was seen as a rejection of traditional societal norms and threatened the Cold War-imposed gender ideology. In addition, the fear of Communist expansion led to the conflation of homosexuals and Communists, categorizing queerness and queer-related themes as immoral and as an interference in the United States' fight for democracy. Specifically, this paper seeks to answer how national defense tactics led to the villainization of queerness and the censoring of queer themes in books. I argue that book bans during the Cold War were a form of internal regulation intended to protect the public from exposure to queerness and to protect the nuclear family. I aim to understand the process of book banning by using two different queer texts, Giovanni's Room by James Baldwin and Women's Barracks by Tereska Torrès, and their public reception as proxies for understanding the more significant effect of Cold War queer book-banning campaigns.
“Into the Sea of Forgetfulness”: An Analysis of Anna Komnene’s Alexiad in Relation to the First Crusade
Authors: Scarlett Breya D.
Published: October 2024

Anna Komnene’s account of the First Crusade in her work The Alexiad provides invaluable insight into the Byzantine perspective of this pivotal event defining the 11th century. While shunned in a monastery, she wrote her celebrated work known as The Alexiad. Anna’s primary motivation for writing the biography stems from her desire to emphasize the accomplishments of her father, especially in regards to protecting the Byzantine Empire against invaders, both Latin and Turkish. For Anna, the crusade functions as a Western pretext for taking land away from the Byzantines. Comparing specific sieges in the First Crusade to their Latin counterparts provides a significantly more nuanced comprehension of the Crusades from a Christian perspective. Anna's Byzantine perspective contradicts the simplified characterization of the First Crusade as a united Christian front against the Muslim forces.
FOSİL YAKIT ENDEKS FİYATLARININ YENİLENEBİLİR ENERJİ HİSSE ENDEKS FİYATLARI ÜZERİNDEKİ ETKİSİ: ERIX ÖRNEĞİ

Published: October 2024

Sürdürülebilir enerjiye doğru devam eden küresel değişimde, geleneksel fosil yakıtlar ile yeni ortaya çıkan yenilenebilir enerji kaynakları arasındaki ilişki yoğun ilgi gören bir konudur. Küresel enerji ortamı, geleneksel fosil yakıt kaynakları ile gelişen yenilenebilir enerji alternatifleri arasındaki etkileşimin sadece ekonomik dinamikleri değil aynı zamanda çevresel sürdürülebilirliği de şekillendirdiği kritik bir kavşakta durmaktadır. Bu dinamik ortamda finansal piyasalar, fosil yakıt ve yenilenebilir enerji sektörleri arasındaki karmaşık ilişkiyi yansıtan bir barometre görevi görmektedir. Bu çalışma, geleneksel enerji piyasasının sağlığının önemli bir göstergesi olan fosil yakıt endeks fiyatlarındaki dalgalanmaların yenilenebilir enerji hisse senedi endekslerinin performansını nasıl etkilediğini araştırmaktadır. Bu bağlamda çalışmada Avrupa Yenilenebilir Enerji Endeksi (ERIX) ile Fosil Yakıt Endeks Fiyatları arasında bir ilişki olup olmadığının tespit edilmesi amaçlanmıştır. 2018-2023 yılları arası günlük verilerin kullanıldığı çalışmada analiz yöntemi olarak VAR modeli kullanılmıştır. Çalışma sonucunda ERIX üzerinde sadece Rotterdam Kömür (ARA) endeksinin etkili olduğu, diğer endekslerin ise bir etkisinin olmadığı tespit edilmiştir.

Published: October 2024

Bu çalışmada, kredi temerrüt takası ile enflasyon, BIST100 endeksi ve VIX endeksi arasındaki kısa ve uzun dönemli ilişkilerin incelenmesini amaçlamaktadır. Bu amaç doğrultusunda, 2008-2024 dönemi için ARDL-PMEG modeliyle kısa ve uzun dönemli esneklik katsayıları tahmin edilmiştir. Değişkenler arasındaki nedenselliğin belirlenmesi amacıyla Granger nedensellik testi uygulanmıştır. Araştırma sonucunda, ARDL tahmin yöntemine göre CDS ile açıklayıcı değişkenler arasında uzun dönemde ilişki olduğu belirlenmiştir. Uzun dönem tahmin sonuçlarına göre CDS’in enflasyon ve VIX endeksiyle pozitif, BIST00 endeksiyle negatif ilişkili olduğu tespit edilmiştir. Kısa dönem tahmin sonuçları kısa dönemde ortaya çıkan dengesizliklerin enflasyon ve BIST100 değişkenleri ile giderilebildiğini ancak VIX endeksinin CDS üzerinde etkili olmadığını göstermektedir. Nedensellik analizleri sonucunda, enflasyon ve BIST100 endeksinin CDS’in Granger nedeni olduğu tespit edilmiştir. Dolayısıyla, yüksek risk seviyesine sahip ülkelerin politika yapıcılarının özellikle yabancı yatırımcılar için güvenilir, düşük riskli, yüksek getirili piyasa ortamını destekleyen politikalar geliştirmesi önerilmektedir.
A MÚSICA NO PROCESSO DE ENSINO E APRENDIZAGEM NA EDUCAÇÃO INFANTIL
Authors: Marafon Danielle , Maciel Neta Maria Cidalha
Published: October 2024

O presente artigo investigou o papel da música no processo de ensino e aprendizagem na educação infantil, com foco em uma instituição em Paranaguá-PR. Reconhecendo a música como uma linguagem universal que impacta tanto fisicamente quanto psicologicamente, o estudo explorou como ela é utilizada na prática pedagógica das professoras de educação infantil, por meio da pesquisa qualitativa e utilizando de instrumento de coleta de dados um questionário. A música foi reconhecida como uma poderosa ferramenta educativa, capaz de estimular não apenas a audição, mas também outras áreas do desenvolvimento infantil, incluindo cognição, linguagem, coordenação motora e socialização. Embora algumas professoras tenham demonstrado uma integração mais abrangente da música em suas atividades pedagógicas, outras a utilizaram de forma mais pontual, em momentos específicos da rotina escolar. Isso sugere uma variação na profundidade com que a música é incorporada ao currículo da educação infantil, com potencial para ampliar seu uso como uma ferramenta educativa mais significativa e abrangente.
Contribution of Unsteadiness to Solid Fuel Burning Characteristics in a Scramjet Combustor
Authors: Pace Henry , Schlussel Ethan , Young Gregory , Massa Luca
Published: October 2024

The contributions of unsteadiness to solid fuel combustion are investigated numerically and validated against new experiments in a deep cavity scramjet. Large-eddy simulations discretized with discontinuous Galerkin (DG) elements are solved with a flamelet manifold approach in three dimensions. A multiphase model that incorporated thermal decomposition inside the foam layer is coupled with stagnation flow flames to determine the combustion manifold and regression rate. The approach accurately models small-scale experiments of convective burning over solid fuel. The inclusion of the manifold into the DG code features two innovations: a polynomial fitting of the pressure to reduce the interpolation dimensions and the coefficient of determination to include non-monotonic manifolds in DG schemes. Model validation was performed using pressure and averaged regression rate data, both of which showed strong agreement with experiments. Three-dimensional pressure modes in the cavity support a substantial increase in regression rates and a broadening of the peak due to oscillations of the impingement point. The majority of fuel is pyrolyzed at the shear-layer reattachment point in a stagnation flow boundary layer. The fuel in the cavity is pyrolyzed by conductive heat transfer from the main shear layer. Poor combustion is observed in the expanding fuel section.

To achieve high-accuracy solar radiation pressure analysis, this study proposes a new high-accuracy and high-efficiency (HAHE) shadow function model considering the oblateness of the Earth, for the oblateness of the Earth has much influence in the calculation of the shadow factor. The sphere shadow function model has been improved in this study with an accurate shadow function that considers the Earth’s oblateness. Then, using the accurate shadow function model, a new HAHE shadow function model is proposed to calculate a simulated satellite orbit’s changes of shadow factor, which is analyzed and compared with the existing shadow function model and the accurate shadow function model. The results show that the difference between the HAHE shadow function and the accurate shadow function is tiny. Moreover, the HAHE shadow function is 113 times faster than the accurate shadow function model.

Commercial aviation crew sizes have historically shrunk and are only projected to shrink down further to a one-member crew, known as single-pilot operations. Single-pilot operations involve a redesign of the modern two-person flight deck, as the work of the second pilot is now displaced to either enhanced ground support or increased automation. This paper focuses on cognitive assistants, a solution for work displacement within the latter domain of increased automation, where artificial intelligence may take the role of the second pilot and provide crucial decision-making, planning, and flight support to the remaining pilot. Work within this area is numerous, but a complete survey of current theory and implementations for cognitive assistants has yet to be completed. Therefore, this paper reviews current analyses and implementations of cognitive assistants within aviation broadly and discusses their potential within single-pilot operations. Gaps and constraints that remain within cognitive assistants for single-pilot operations are also analyzed, and future pathways for the incorporation of cognitive assistants in commercial aviation are identified.
Aerostructural Analysis of a Deployable Aeroshell in Transonic Flow
Authors: Saha Sanjoy Kumar , Takahashi Yusuke
Published: October 2024

The deployable aeroshell, a contemporary reentry system, utilizes a thin flexible membrane surface sustained by pressurized gas to efficiently decelerate a reentry vehicle at high altitudes while enabling low-ballistic-coefficient flight. When an in-flight aerodynamic force is applied, the membrane structure undergoes large deformation that may affect its performance. Hence, a coupled analysis that considers the feedback effect of structural deformation is essential for accurately predicting the behavior of such reentry vehicles. In this study, a numerical framework for coupled aeroelastic analysis was constructed in a partitioned manner using open-source software to elucidate the combined effect of structural deformation and compressible flow dynamics and characterize the aerodynamic performance of reentry vehicles with inflatable structures. The results revealed that the membrane surface was deformed elastically by the aerodynamic force owing to the large difference in pressure distribution between the front and back of the aeroshell. Fluctuating behavior was observed in the aerodynamic coefficients owing to the small-amplitude oscillation of the capsule. This oscillation was induced by the large wake behind the vehicle. Several wrinkles and concave-shaped depressions formed on the membrane surface, which exhibited a circumferential movement tendency with time.
Shock Propagation Through a Square Injector: Investigation into Rotating-Detonation Engine Injector Dynamics

The rotating detonation engine is perhaps the most promising means to realize pressure-gain combustion in modern engines. The physical processes underpinning the dynamics of the combustion wave are complex, and a lack of understanding of these processes represents a significant barrier to practical implementation of the technology. A significant simplification of the RDE is considered through an abstracted experimental setup. The detonation wave is replaced with a nonreacting shock generated by a shock tube, and the annulus is unwrapped into a single linear channel. Both simplifications make direct visualization of the problem via schlieren imaging tractable. Several performance metrics are used to relate the fluid-dynamic behavior of the shock–injector interaction to the performance of a theoretical rotating detonation engine. The first such metric is “recovery time,” based on the time taken for the injector to return to a fully flowing state after the passage of a detonation wave. The second such metric not only considers the mass flow through the injector exit but also accounts for potential backflow into the injector nozzle that may occur for sufficiently strong waves. Finally, a reactant mass-deficit metric is used to characterize the reduction in mass injection due to the interaction with the wave.

Published: October 2024

In general, for installing multilayer insulation (MLI) blankets on curved spacecraft equipment, creating a pattern that has multiple sectors is necessary because of the impossibility of establishing a single piece of MLI. The sector area of the MLI contains numerous seams and sewing. Therefore, prediction of overall performance or effective emittance is not simply possible, and they need to be tested in some experimental ways. The aim of the current research is to present a methodology for determining the conductivity between layers in both nonsewing and sewing regions of MLI to correctly estimate the effective emittance coefficient and the thermal behavior of MLI. Firstly, by conducting two experimental tests, both sewn and nonsewn square MLIs’ effective emittance coefficients are computed. In the second step, the conductive thermal coupling coefficients of nonsewing and sewing regions are determined as 1.615 and [Formula: see text] respectively, utilizing experimental data. In the third step, a spherical geometry fuel tank is selected as a case study, and these coefficients are utilized in the simulation process of an MLI tank. Finally, the overall effective emittance coefficient of that tank is determined. The results indicate that the effective emittance is reduced by about 8%.

Наведено аналіз існуючих способів лазерного різання та представлено особливості конструктивного та технологічності вдосконалення процесу за рахунок вигладжування поверхні різів. Експериментальні дослідження, полягали в порівнянні впливу розмірів вигладжувальної кульки на якість обробленої поверхні. Встановлено, що нерівності на поверхнях різів, оброблених кульками різного діаметра, деформуються майже однаково, хоча сліди від лазерного різання скрізь залишаються. Показані результати впливу діаметра кульки на зміну мікротвердості та товщину зміцненого шару, а також величину максимального залишкового напруження на поверхні різу після вигладжування та глибину цих залишкових напружень. Розширення функціональності існуючого на ринку лазерного обладнання полягає у модернізації за рахунок встановлення пристрою для вигладжування на рухому каретку, де розміщена лазерна фокусуюча головка. При цьому кульковий інструмент при вигладжуванні переміщувався по контуру деталі за іншою програмою, ніж при газолазерній різці, так щоб контур руху інструменту був еквідистантним до вирізаної деталі. Конструктивне розташування пристрою для вигладжування вище точки фокусування лазерного випромінювання не буде перешкоджати операціям контурного газолазерного різання. Представлені технологічні та конструктивні рішення дозволяють знизити вартість виробу за рахунок зниження трудомісткості подальших слюсарних робіт в результаті зниження шорсткості поверхні різу та дають можливість отримати деталі з більшою міцністю їх поверхні проти втоми. Матеріальні затрати на виконання такої модернізації на кілька порядків нижчі вартості самого лазерного обладнання.
Outpatient Physiotherapy for Immune-Mediated Necrotizing Myositis With a Positive Outcome: Must Pathology Equal Dysfunction? A Case Report
Authors: Neufeld Alex , Johnson Michael , Wong Christopher K.
Published: October 2024

BACKGROUND: Necrotizing myositis (NM) is a rare autoimmune systemic condition leading to skeletal muscle destruction visualized on magnetic resonance imaging (MRI). The prognosis is severe progressive muscle weakness leading to functional mobility decline. This case study described outpatient physiotherapy management of NM, not hitherto reported, and the unanticipated outcomes given the diagnosis and MRI findings.

CASE PRESENTATION: A 77-year-old female was diagnosed with NM, confirmed on MRI significant for abnormal T2 signal in all muscular compartments of both lower extremities, after 4 months of progressive limb weakness had prevented her from walking independently. Outpatient physiotherapy began 10 months after diagnosis. Examination revealed spinal and peripheral joint hypomobility, lower limb weakness (1 repetition, 30s sit to stand-30STS), functional limitation (14/80, Lower Extremity Functional Scale [LEFS]), and slow gait with rollator. The physiotherapy diagnosis was that musculoskeletal impairments contributed to movement dysfunction, leading to 18 manual therapy and exercise treatments over 19 weeks.

OUTCOMES AND FOLLOW-UP: Strength (8 repetition 30STS) and function (49/80 LEFS) improved beyond minimal clinical important differences and gait speed at discharge approximated age-sex-matched normal.

DISCUSSION: For this NM case, strength and function improved despite confirmed muscle necrosis and prognosis of progressive muscle degradation after addressing modifiable musculoskeletal impairments. JOSPT Cases 2024;4(4):205-211. Epub 7 October 2024. doi:10.2519/josptcases.2024.0064
Teoria crítica da tecnologia: uma reflexão a partir das contribuições de Andrew Feenberg
Authors: De Lima Dusi Luciana
Published: October 2024

The objective of this article is to present ways of understanding technologies based on Andrew Feenberg's critical theory. From a methodological point of view, this is a bibliographic study that addresses the foundations of instrumentalism, determinism and substantivism, as well as the influences that contributed to the formulation of the critical theory of technology. It is concluded that technologies can be understood as neutral, inevitable, faithful to the rules of efficiency, autonomous and capable of incorporating substantial values. The critical theory of technology adds that they can be considered the result of the technical knowledge of the experts involved in the technological project added to the experiences of its users. The democratic conception of technology emerges from this understanding, as a way for users to influence the technological project, in order to represent different interests and different contexts.

Post-translational modifications (PTMs) of histone proteins play a pivotal role in the regulation of chromatin condensation, with evidence increasingly pointing to the involvement of liquid–liquid phase separation (LLPS). Here, we report the significant impact of the acetylation site of the N-terminal histone H3 peptide on LLPS with nucleosomal-linker DNA. In our model system, which mimics a part of the structure of chromatin, non-acetylated H3 peptide and DNA undergo LLPS, driven primarily by electrostatic interactions. Acetylation of the H3 peptide significantly inhibits LLPS, with the inhibitory effects varying markedly depending on the acetylation site. Specifically, acetylation near the ends of the 20-residue H3 peptide (i.e., H3K4ac and H3K18ac) results in stronger inhibition of LLPS compared to acetylation near the center (i.e., H3K9ac and H3K14ac). Through experiments (circular dichroism and interaction assays using salts and 1,6-hexanediol) and molecular-dynamics (MD) simulations, it was revealed that differences in the DNA thermal stability, hydrophobic effects, and charge distribution of the H3 peptides/DNA complexes underlie this phenomenon. Our findings provide fundamental insights that link LLPS-mediated chromatin condensation to various biological phenomena depending on the acetylation sites on the histone proteins, thus shedding light on the mechanisms of gene regulation.
