Authors: Nguyễn Hữu Quyết , Lê Văn Vũ , Trần Ngọc Hoà
Published: December 2024

Trong lĩnh vực giám sát sức khỏe kết cấu (SHM), việc nghiên cứu các mô hình học sâu như mạng nơ-ron tích chập một chiều (1DCNN) để xử lý, phân tích các bộ dữ liệu thời gian đã được đặc biệt quan tâm. Tuy nhiên, mô hình 1DCNN không đạt được độ chính xác cao với dữ liệu có chiều dài quá lớn. Do đó, nghiên cứu này đề xuất phân loại chính xác hư hỏng trong kết cấu khung thép bằng cách kết hợp 1DCNN với cơ chế chú ý kênh (CA). Sự kết hợp này cải thiện hiệu năng của mô hình trong việc tập trung vào các đặc trưng nổi bật trong dữ liệu chuỗi thời gian, từ đó nâng cao độ chính xác trong phân loại. Nghiên cứu áp dụng bộ dữ liệu Qatar University Grandstand Simulator (QUGS), một bộ dữ liệu quy mô lớn được xây dựng cho mục đích kiểm tra hiệu quả các mô hình trong lĩnh vực SHM. Thông qua quá trình huấn luyện, mô hình đề xuất 1DCNN-CA đạt hiệu suất vượt trội so với mô hình 1DCNN truyền thống, với độ chính xác cao hơn trong cả hai tập dữ liệu xác thực và kiểm tra lần lượt là 95,7% và 93,6%. Các kết quả thu được cho thấy việc tích hợp cơ chế chú ý kênh cải thiện đáng kể độ chính xác của các mô hình học sâu trong bài toán phân loại hư hỏng và có nhiều tiềm năng trong các vấn đề thuộc lĩnh vực SHM

Progressive multifocal leukoencephalopathy, the role of the susceptibility-weighted imaging sequence in a case of immunosuppression of an initially unknown cause
Authors: D’Arma Giuseppe Maria Andrea , Balzano Rosario Francesco , Masino Federica , Guglielmi Giuseppe
Published: December 2024

We describe the case of a 47-year-old woman who was confused and complained about left-sided weakness when she presented to our institution. The patient underwent a head computed tomography that raised the suspicion of a recent-onset ischemic episode (subacute phase). The patient was admitted to the neurology department and underwent a magnetic resonance imaging (MRI) with contrast medium administration. The clinical and laboratory findings and the MRI features, particularly the presence of a hypointense rim in the susceptibility-weighted imaging (SWI) sequences, were consistent with a diagnosis of progressive multifocal leukoencephalopathy (PML). Immunosuppression was observed as a result of lymphopenia, and the patient was subsequently diagnosed with previously undocumented AIDS. Our aim is to present this rare case of PML in an immunocompromised patient with AIDS, describing the main MRI features and the possible role of SWI sequences.
O sentido da vida no longa-metragem “soul”
Authors: RIBEIRO MARIANA
Published: December 2024

Este artigo visa analisar o sentido da vida presente no longa-metragem “Soul” (2020) com base na logoterapia de Viktor Frankl. A animação trouxe, por acaso ou não, indagações do que seria o sentido da vida à sua plateia, mostrando a complexidade do consenso acerca desta temática. Assim, é essencial que tramitemos por esses temas que perpassam as existências de Joe Gardner e 22, personagens do filme, para compreender o sentido da vida para a logoterapia. Experiências como angústia, finitude, vazio existencial e autenticidade demonstram que a existência tem sentido exatamente por ser experienciada e por possuir tempo e possibilidades limitadas. Diante disso, pretendemos a hipótese de relação do sentido da vida no filme com os processos de angústia e autenticidade de Joe Gardner e 22.
"Güncel Türkçe Sözlük" ile "Kubbealtı Lugatı"nda Kelime Türleri Bilgisinin Kullanımı Açısından "Güzel" Kelimesi
Authors: Delice Hacı İbrahim
Published: December 2024

Sözlüklerde maddebaşı yapılan kelimelerin türlerine genelde yer verilmektedir; ancak, kelimelerin tür bilgilerinin verilme şekli sözlüklerde farklılıklar da gösterebilmektedir. Aynı zamanda, bir kelimenin türü farklı cümlelerde isim, sıfat, zarf vb. tanımlarına uyacak şekilde değişebilmektedir. Kelime türü bilgilerinin sözlüklerde sağlıklı verilebilmesi için maddebaşı olan kelimeye yazılan her anlama, uygun bir tanık cümlesi de verilmelidir. Tanık cümlesine göre tespit edilen kelime türünün de dilbilgisi ölçütleri çerçevesinde doğru olması beklenmektedir. Ne var ki, Türkçe için pek çok sözlük yazılmış olmasına rağmen bu sözlüklerde oturmuş bir sözlükbilim ilkeleri henüz oluşmamıştır. Bu çalışmada, "güzel" kelimesinin en çok bakıldığı düşünülen ve internet ortamında bireylerin kullanımına sunulan Türk Dil Kurumunun "Güncel Türkçe Sözlüğü" ile Kubbealtı Akademisi Kültür ve Sanat Vakfının "Kubbealtı Lugatı"nda kelime türleri açısından karşılaştırılması yapılmış ve her iki sözlükteki kelime türü bilgilerinin dilbilgisi ölçütlerine uymadığı düşünülen hususları ortaya konmuştur. Çalışmanın amacı, sözlükçülük çalışmalarının daha bilimsel bir zemine oturmasına katkıda bulunmak ve mevcut sözlüklerin yeni basımlarında kelime türü bilgisi açısından yanlışlıklarının düzeltilmesine katkı sağlamaktır.

Authors: Bulut Atalay Esra , Ayar Kayalı Hülya
Published: December 2024

Metabolite analysis is critical in the cancer field because of provides information about the metabolic status of cells. The profiling of extracellular metabolites presents technical advantages over intracellular metabolites, such as easier access to extracellular metabolites without a quenching method and the growth medium containing high biomass. This study aimed to investigate the extracellular level of metabolites in colon cancer cells in a time-dependent manner. One million cells were seeded in 4 Petri dishes and glucose, pyruvate, TCA cycle metabolites, and D2-HG in the conditioned medium were determined by DNS and HPLC method and pyruvate assay for 24-96th hours. The results showed that glucose is consumed, and pyruvate and TCA cycle intermediates are released in decreasing amounts in all cell lines. It was also observed that glucose was more consumed, and TCA cycle metabolites were less released in metastatic colon cancer cells (SW620) than in primary colon adenocarcinoma cells (Caco-2). Most importantly, D2-HG oncometabolite was released more into the growth medium of colon cancer cells than normal colon cells for four days. In conclusion, the D2-HG is highly produced and released to the growth medium of colon cancer cell lines in a cancer-type-specific manner.

Sharing Yerba Mate
Authors: Pite Rebekah E.
Published: December 2024

Drinking yerba mate is a daily, communal ritual that has brought together South Americans for some five centuries. In lively prose and with vivid illustrations, Rebekah E. Pite explores how this Indigenous infusion, made from the naturally caffeinated leaves of a local holly tree, became one of the most distinctive and widely consumed beverages in the region. Latin American food and commodity studies have focused on consumption in the global north, but Pite tells the story of yerba mate in South America, illuminating dynamic and exploitative circuits of production, promotion, and consumption. Ideas about who should harvest and serve yerba mate, along with visions of the archetypical mate drinker, persisted and were transformed alongside the shifting politics of class, race, and gender. This global history takes us from the colonial Río de la Plata to the top yerba-consuming and producing nations of Argentina, Brazil, Paraguay, and Uruguay, with excursions to Chile, the Middle East, Europe, and the United States, where yerba mate is now sold as a "superfood." For readers eager to understand South America and its unique drink, Sharing Yerba Mate is an essential text that delves into an everyday ritual to expose systems of power and the taste of belonging.
Narrating and focalizing the Book of Margery Kempe
Authors: Amsler Mark
Published: December 2024

Narratology can profit from more historicized attention to premodern texts. This essay opens an extended narratological analysis of the fifteenth-century Middle English Book of Margery Kempe. Modifying narrative theory (Genette, Bal) to suit a medieval narratology, I use discourse analysis to explore the language, focalization, and temporality of the narrating discourse. The text, seemingly without a narrator, deploys multiple focalizations to construct an intricate third-person narrative rather than a strict autobiography of the life of a lay, extravagantly pious, and visionary woman. Some focalizations are internal (Experiencers), while others are external (Summarizer, Commentator, Scribal-Textualist). The lively narration weaves together homodiegetic and heterodiegetic perspectives. The narration constructs multifocalized accounts of the protagonist’s everyday struggles and interactions and her interior experiences and visions of Jesus suffering in the Passion and “fresch” on the streets. Narratological analysis uncovers the textual power of narrating the protagonist’s life story with transplacing temporalities of Apostolic past, near past, and present reading time.

Introdução: A gestação é uma experiência inigualável e repleta de novidades na vida de uma família, especialmente para a mulher que vivencia este processo intensamente. Com isso, a escolha do método de parto é uma das decisões cruciais a serem consideradas durante a gestação. Apesar da tendência de optar pela cesariana devido à sua rapidez, menor dor e frequentemente por recomendação médica, é importante destacar que pode trazer complicações significativas tanto para mãe como para o recém-nascido. Objetivo: Investigar os impactos da cirurgia cesariana no aleitamento materno e nos primeiros cuidados com o recém-nascido. Metodologia: Trata-se de uma revisão integrativa da literatura, a qual teve como pergunta norteadora "Quais os impactos da cirurgia cesariana no aleitamento materno e nós primeira cuidados com o recém-nascido?", a qual será realizada na Biblioteca Virtual em Saúde (BVS), através das bases de dados online Scientific Eletronic Library Online (SCIELO), Literatita Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Medical Literature Analysis and Retrieval System Online (MEDLINE), utilizando os seguintes descritores: "parto", "aleitamento materno", "cesárea", “recém-nascido”, combinados com os operador booleano AND, onde foram incluídos os artigos completos em português, inglês e espanhol e foram excluídos trabalhos que não estão de acordo com a temática proposta. Resultados: Após a busca foram encontradas 16 publicações na BDENF, 41 na MEDLINE e 76 na LILACS. Na segunda etapa, usando os filtros com os critérios de inclusão e exclusão, o quantitativo foi reduzido a 4 artigos na BDENF, 4 na MEDLINE e 6 na LILACS. Realizada a releitura de cada artigo, foram identificados 8 para elaboração do quadro sintético. Perante a análise, este estudo enfatizou em seus resultados que, a decisão sobre o método de parto deve sempre considerar a saúde da mãe e do bebê, e a cesariana deve ser indicada apenas em situações em que os benefícios superem os riscos. Considerações finais: O parto cesáreo está ligado a vários efeitos perinatais adversos e complicações na saúde do recém-nascido como prematuridade, maiores necessidades de cuidados intensivos e problemas respiratórios, além de impactar negativamente, principalmente, no início da amamentação e no contato pele a pele, fatores que são de suma importância para o desenvolvimento infantil.

Storm Daria: Societal and energy impacts in northwest Europe on 25–26 January 1990
Authors: Kettle Anthony J.
Published: December 2024

Abstract. Between late January and early March of 1990 Europe was hit by a sequence of severe winter storms that caused significant infrastructure damage and a large number fatalities. The storm sequence started with Hurricane Daria on 25–26 January 1990, which was one of the most serious events of the storm cluster, especially for the UK. The low pressure centre moved in a west-northwest direction across Ireland, southern Scotland, and north of Denmark before moving further into the Baltic. The strongest winds south of the trajectory path caused significant damage and disruptions in England, France, Belgium, the Netherlands, and West Germany. Media reports highlighted building damage, interrupted transportation networks, power outages, and fatalities. There were also a series of maritime emergencies in the Bay of Biscay, English Channel, North Sea, and Baltic Sea. This contribution takes a closer look at Storm Daria, presenting an overview of meteorological measurements and the societal impacts, followed by an analysis of the North Sea tide gauge network to understand the storm surge and possible large wave occurrences. Offshore wind energy was at the planning stage in this early period, but onshore wind energy was established in Denmark with demonstration projects in other countries. The storm is an important case study of extreme meteorological conditions that can impact energy infrastructure.
Phytoplankton adaptation to steady or changing environments affects marine ecosystem functioning
Authors: Hochfeld Isabell , Hinners Jana
Published: December 2024

Abstract. Global warming poses a major threat to marine ecosystems, which fulfill important functions for humans and the climate. Ecosystem models are therefore increasingly used to estimate future changes in the functioning of marine ecosystems. However, projections differ notably between models. We propose that a major uncertainty factor in current models is that they ignore the high adaptive potential of phytoplankton, key players in marine ecosystems. Here, we use a zero-dimensional evolutionary ecosystem model to study how phytoplankton adaptation can affect estimates of future ecosystem-level changes. We found that phytoplankton adaptation can notably change simulated ecosystem dynamics, with the effect depending on environmental conditions. In a steady environment, adaptation allows for a more efficient use of resources, which enhances primary production and related ecosystem functions. In a warming environment, on the contrary, adaptation mitigates dominance changes among functionally different taxa and consequently leads to weaker changes in related ecosystem functions. Our results demonstrate that by neglecting phytoplankton adaptation, models may systematically overestimate future changes in the functioning of marine ecosystems. Future work can build on our results and include evolutionary processes into more complex model environments.
Red Hot Steel: Challenges of 3D Optical Metrology in Open-Die Forging
Authors: Tarabini Marco
Published: December 2024

Abstract. Complex challenges arise from the integration of 3D optical metrology in contemporary steelmaking and metal-working operations. Contrary to expectation, the greatest difficulties do not arise from the obstacles posed by high temperatures or harsh environments requiring robust measurement solutions. Often, there's a nuanced understanding of metrology concepts, with experts struggling to distinguish between instrumental uncertainty, measurand variability and definitional uncertainty. This paper aims to underscore the importance of technological innovation and interdisciplinary collaboration in efficiently adopting 3D optical measurement systems in modern metalworking industries. A case study focused on a 2D profilometer is presented and discussed.
Optimizing Bundle Block Adjustment for High-Overlap Small-Format Multi-Head Camera Systems
Authors: Bannakulpiphat Thirawat , Karel Wilfried , Ressl Camillo , Pfeifer Norbert
Published: December 2024

Abstract. Small-format multi-head camera systems integrating nadir and oblique cameras are becoming standard in photogrammetry, offering the versatility needed for UAV-based mapping and surveying applications to collect high-quality data in challenging environments. A key consideration for these systems is the inherent limitations due to their small size, which may lead to various trade-offs, such as reduced ground coverage, overlap, and image quality, as well as constraints on using high-precision instruments like GNSS and INS. In this contribution, we propose the compass direction (CD) frame as a superior reference frame to avoid confusion regarding oblique cameras and oblique viewing directions. This approach supports continuous and consistent ground coverage, similar to the nadir camera, and facilitates easier analysis. We focus particularly on relative orientation, as it is a decisive factor for the consistency of subsequently derived information. We evaluate various influencing factors, including image connectivity, image ray intersection angle, and tie point multiplicity, in both single-camera (nadir) and penta-camera (nadir and oblique). The analysis reveals significant deviations in image connectivity from proportionality to image overlap. The percentage of overlap and side lap for nadir images influences the overlap for oblique cameras. While, there are no gaps at the near line between overlapping frames in each individual compass direction, the nadir images overlaps do not result in the same symmetry in the oblique image overlaps. Achieving such symmetry could enhance the visibility of facades in oblique images. In terms of the image ray intersection angle, the maximum intersection angles per tie point are well below the theoretical maximum, indicating a moderate exploitation of the accuracy potential offered by oblique images. Furthermore, analysis of the RMS error suggests that by adding the oblique images to the nadir image block and removing the 2-fold tie points, vertical accuracy improved considerably, while planimetric accuracy remained consistent.
Density-based Geometric Convergence of NeRFs at Training Time: Insights from Spatio-temporal Discretization
Authors: Haitz Dennis , Kıvılcım Berk , Ulrich Markus , Weinmann Martin , Weinmann Michael
Published: December 2024

Abstract. Whereas emerging learning-based scene representations are predominantly evaluated based on image quality metrics such as PSNR, SSIM or LPIPS, only a few investigations focus on the evaluation of geometric accuracy of the underlying model. In contrast to only demonstrating the geometric deviations of models for the fully optimized scene model, our work aims at investigating the geometric convergence behavior during the optimization. For this purpose, we analyze the geometric convergence of discretized density fields by leveraging respectively derived point cloud representations for different training steps during the optimization of the scene representation and their comparison based on established point cloud metrics, thereby allowing insights regarding which scene parts are already represented well within the scene representation at a certain time during the optimization. By demonstrating that certain regions reach convergence earlier than other regions in the scene, we provide the motivation regarding future developments on locally-guided optimization approaches to shift the computational burden to the adjustment of regions that still need to converge while leaving converged regions unchanged which might help to further reduce training time and improve the achieved quality.

The welding process plays a crucial role in manufacturing and is inseparable from its advancement. Deutsche Industrie Norman (DIN) defines welding as creating a metallurgical bond at the joint of metal or alloy metals in their molten state. This process is essential for constructing strong, durable materials like plates, steel, and pipes. Bending tests, including face bend and root bend, are often conducted to evaluate the quality of welded joints. These tests assess welded materials’ toughness, strength, and resistance under specific loading conditions. This study employed two welding techniques: Gas Metal Arc Welding (GMAW) and Shielded Metal Arc Welding (SMAW). GMAW, called Metal Inert Gas (MIG) welding, uses argon or helium as protective gases and a continuously fed electrode wire. On the other hand, SMAW relies on flux-coated electrodes to create the weld seam, with molten metal from both the electrode and parent material filling the joint. The results revealed distinct advantages for each method. The highest bending test value for the root bend was achieved with MIG welding at 982,55 Kgf/mm², demonstrating its effectiveness in creating durable root joints. Conversely, SMAW exhibited superior performance in face bend tests, achieving a bending strength of 104111 Kgf/mm², making it ideal for surface-level joint applications. Both techniques displayed no visible cracks in their welds, ensuring compliance with industry standards and confirming their reliability for various manufacturing needs. These findings highlight the importance of selecting appropriate welding methods based on specific application requirements.

This study aimed to explore the relationship between specific cognitive errors—catastrophizing, overgeneralization, and personalization—and mental health issues, including anxiety, depression, and stress, among adolescents. Additionally, the study sought to investigate gender differences in how these cognitive errors contribute to mental health problems. A quantitative, correlational research design was used, involving a sample of 600 adolescents aged 12-18 years. Standardized instruments, such as the Cognitive Errors Scale (CES), Generalized Anxiety Disorder Scale (GAD-7), Beck Depression Inventory (BDI-II), and Perceived Stress Scale (PSS), were employed to assess cognitive errors and mental health symptoms. Data were analyzed using SPSS, with descriptive statistics, correlation analysis, regression analysis, and t-tests used to evaluate relationships and gender differences. The findings revealed significant positive associations between cognitive errors and mental health problems, such as anxiety, depression, and stress. Additionally, gender differences were observed, with girls reporting higher levels of cognitive errors and more severe mental health distress compared to boys. This study contributes to the literature by offering a deeper understanding of the impact of cognitive errors on adolescent mental health and emphasizing the need for gender-sensitive interventions. The findings are significant for developing targeted therapeutic strategies that address cognitive distortions, ultimately promoting better mental health outcomes for adolescents.

One of the bioindicators of soil fertility is soil macrofauna. Macrofauna acts as a decomposer of organic matter so that it can increase nutrient distribution and improve the physical, chemical and biological properties of the soil. Soil macrofauna is also very sensitive to environmental changes. Changes in land use for oil palm commodity production areas are related to changes in soil biodiversity. This study aims to compare the diversity of soil macrofauna in oil palm plantations of different ages. This research was conducted by survey method and determining the location of research with the Purpossive Sampling method. Sample points were taken on the palm oil disc, live and interrow. Sampling was done using a box sampler, followed by a hand sorting method and identified to the family level. Macrofauna calculations are performed on the number of families, population density (KP), relative density (KR), Shannon-Wiener index (H ') and evenness index (E'). Data obtained were analyzed statistically using a t-test at 5% level. The results showed that the average number of soil macrofauna families tended to be higher in 13 year old oil palms in interrow (GM), namely 12.83 ± 1.33. Eight families of soil macrofauna that have a higher population density and relative density than other families are Termitidae, Formicidae, Lumbricidae, Cylisticidae, Lithobiidae, Anisolabidiidae, Mecistocphalidae, and Geophilidae. The diversity index of soil macrofauna in 13 year old oil palms tends to be higher in the interrow (GM) area, namely 2.49 ± 0.18 (medium) compared to the others. The evenness index of soil macrofauna in 5 year and 13 year old oil palms was included in the high category (>0.5), namely 0.63-0.73.
