Stitched vision transformer for age-related macular degeneration detection using retinal optical coherence tomography images
Authors: Azizi Mohammad Mahdi , Abhari Setareh , Sajedi Hedieh
Published: June 2024

Age-related macular degeneration (AMD) is an eye disease that leads to the deterioration of the central vision area of the eye and can gradually result in vision loss in elderly individuals. Early identification of this disease can significantly impact patient treatment outcomes. Furthermore, given the increasing elderly population globally, the importance of automated methods for rapidly monitoring at-risk individuals and accurately diagnosing AMD is growing daily. One standard method for diagnosing AMD is using optical coherence tomography (OCT) images as a non-invasive imaging technology. In recent years, numerous deep neural networks have been proposed for the classification of OCT images. Utilizing pre-trained neural networks can speed up model deployment in related tasks without compromising accuracy. However, most previous methods overlook the feasibility of leveraging pre-existing trained networks to search for an optimal architecture for AMD staging on a new target dataset. In this study, our objective was to achieve an optimal architecture in the efficiency-accuracy trade-off for classifying retinal OCT images. To this end, we employed pre-trained medical vision transformer (MedViT) models. MedViT combines convolutional and transformer neural networks, explicitly designed for medical image classification. Our approach involved pre-training two distinct MedViT models on a source dataset with labels identical to those in the target dataset. This pre-training was conducted in a supervised manner. Subsequently, we evaluated the performance of the pre-trained MedViT models for classifying retinal OCT images from the target Noor Eye Hospital (NEH) dataset into the normal, drusen, and choroidal neovascularization (CNV) classes in zero-shot settings and through five-fold cross-validation. Then, we proposed a stitching approach to search for an optimal model from two MedViT family models. The proposed stitching method is an efficient architecture search algorithm known as stitchable neural networks. Stitchable neural networks create a candidate model in search space for each pair of stitchable layers by inserting a linear layer between them. A pair of stitchable layers consists of layers, each selected from one input model. While stitchable neural networks had previously been tested on more extensive and general datasets, this study demonstrated that stitching networks could also be helpful in smaller medical datasets. The results of this approach indicate that when pre-trained models were available for OCT images from another dataset, it was possible to achieve a model in 100 epochs with an accuracy of over 94.9% in classifying images from the NEH dataset. The results of this study demonstrate the efficacy of stitchable neural networks as a fine-tuning method for OCT image classification. This approach not only leads to higher accuracy but also considers architecture optimization at a reasonable computational cost.
A large scale bacterial attraction assay: A new quantitative bacterial migration assay suitable for genetic screens
Authors: Quiroz Monnens Thomas , Boulanger Alice
Published: June 2024

Bacteria use various motility mechanisms to explore their environments. Chemotaxis is the ability of a motile bacterial cell to direct its movement in response to chemical gradients. A number of methods have been developed and widely used to study chemotactic responses to chemoeffectors including capillary, agar plug, microscopic slide, and microfluidic assays. While valuable, these assays are primarily designed to monitor rapid chemotactic responses to chemoeffectors on a small scale, which poses challenges in collecting large quantities of attracted bacteria. Consequently, these setups are not ideal for experiments like forward genetic screens. To overcome this limitation, we developed the Large Scale Bacterial Attraction assay (LSBA), which relies on the use of a Nalgene™ Reusable Filter Unit and other materials commonly found in laboratories. We validate the LSBA by investigating chemoeffector kinetics in the setup and by using chemoattractants to quantify the chemotactic response of wild-type, and motility impaired strains of the plant pathogenic bacterium Xanthomonas campestris pv. campestris and the environmental bacterium Shewanella oneidensis. We show that the LSBA establishes a long lasting chemoeffector gradient, that the setup can be used to quantify bacterial migration over time and that the LSBA offers the possibility to collect high numbers of attracted bacteria, making it suitable for genetic screens.

ATP-binding cassette (ABC) transport systems are crucial for bacteria to ensure sufficient uptake of nutrients that are not produced de novo or improve the energy balance. The cell surface of the pathobiont Streptococcus pneumoniae (pneumococcus) is decorated with a substantial array of ABC transporters, critically influencing nasopharyngeal colonization and invasive infections. Given the auxotrophic nature of pneumococci for certain amino acids, the Ami ABC transporter system, orchestrating oligopeptide uptake, becomes indispensable in host compartments lacking amino acids. The system comprises five exposed Oligopeptide Binding Proteins (OBPs) and four proteins building the ABC transporter channel. Here, we present a structural analysis of all the OBPs in this system. Multiple crystallographic structures, capturing both open and closed conformations along with complexes involving chemically synthesized peptides, have been solved at high resolution providing insights into the molecular basis of their diverse peptide specificities. Mass spectrometry analysis of oligopeptides demonstrates the unexpected remarkable promiscuity of some of these proteins when expressed in Escherichia coli, displaying affinity for a wide range of peptides. Finally, a model is proposed for the complete Ami transport system in complex with its various OBPs. We further disclosed, through in silico modelling, some essential structural changes facilitating oligopeptide transport into the cellular cytoplasm. Thus, the structural analysis of the Ami system provides valuable insights into the mechanism and specificity of oligopeptide binding by the different OBPs, shedding light on the intricacies of the uptake mechanism and the in vivo implications for this human pathogen.

Naked Truths
Authors: Pascarella Tedi A.
Published: June 2024

Dr. Joycelyn Elders, medical professional and public health advocate, rose against countless innumerable odds to the highest medical position in the United States of America under President Bill Clinton: surgeon general. Elders and her ideas regarding safe sex and birth control, for example, are central topics of the culture wars of the late twentieth century. Moreover, Elders and her outspoken truths, backed by experience and scientific evidence, came under fire by conservative critics and reveal the intersections of politics, religion, class, and race in American life. Elders resigned after fifteen months in Washington. She continued to navigate her role as a public intellectual outside of governmental administration after she left the Clinton administration by injecting meaningful ideas about universal healthcare and knowledge about human sexuality into public spaces. She inserted herself as an authority into the larger conversations that defined the culture wars of the Clinton era and beyond.
What She Knows for Sure
Authors: Beulah Tejai
Published: June 2024

Oprah Winfrey is one of the most significant women in recent U.S. history. She has influenced nearly every aspect of American society as a talk show host, producer, actress, magazine editor, philanthropist, educator, literary critic, owner of the cable television station OWN: The Oprah Winfrey Network, and as an author. Oprah has done this mainly using personal narrative, a fundamental aspect of African American intellectual and cultural traditions. Winfrey is responsible for popularizing the personal narrative in American culture first through her role as host of The Oprah Winfrey Show, a position she occupied for twenty-five years from 1986 to 2011. More recently, Winfrey has enhanced her personal narrative approach in her spirituality-themed books. This chapter turns to Oprah’s monographs to analyze her preeminence in American society within the larger context of African American intellectual and cultural history.
Smell/Taste
Authors: Fraser Benjamin
Published: June 2024

This chapter of Ben Katchor explores how the artist emphasizes the senses of smell and taste to comment on his preferred urban themes. While many comics are referenced, this chapter includes close readings of “The Normalcy Parfum Company” (from The Beauty Supply District), “Architectural Scents” (from Hand-drying in America), “Jewish Restaurant Culture in Lower Manhattan” (from The Dairy Restaurant), and “Locked Out” (from Hand-drying in America). The role of the sense of smell in everyday life is subjected humorously to the market economy. Katchor’s humorous take on Jewish food culture looks at the dairy restaurants of New York and the presence of canned foods in modern urban life, but also at the role of food and dining in The Garden of Eden.

Duża dynamika zdarzeń społecznych, ekonomicznych i politycznych występujących w ostatnich latach (kryzys finansowy, kryzys migracyjny, pandemia COVID-19, wybuch wojny w Ukrainie w lutym 2022 r. i inne) przyczyniła się do zmian w wielu sferach ludzkiej działalności. W naturalny sposób pojawiają się więc pytania o odporność miast i regionów na skutki zmian, w szczególności tych negatywnych, oraz o sposoby funkcjonowania miast i regionów, a także ich adaptacji do warunków ogólnie pojmowanej niepewności i niestabilności. Wyrażamy nadzieję, że przedstawione w poniższych artykułach wyniki badań w pewnym stopniu pozwalają na przybliżenie problematyki odporności miast i regionów w warunkach niepewności oraz podejmowanych na różnych szczeblach działań mających zapobiegać negatywnym konsekwencjom niepożądanych zdarzeń.
Mobility segregation throughout the lifetime of highly segregated lower social profile inhabitants in Warsaw – case study
Authors: Grzegorczyk Anna
Published: June 2024

The aim of the article is to define the concept of mobility segregation during lifetime and to distinguish mobility segregation scope among two Warsaw (Poland) inhabitants characterised by lower social profile, who lived in homogeneous social environment. Mobility has become a new dimension of social inequality that should be taken into account in research on social segregation in increasingly polarised cities. It can be studied by qualitative methods that can contribute to quantitative-dominant research on segregation. In this paper, mobility segregation aspects are analysed through biographic interviews, using reconstructive-interpretative approach. It gives a novel method to study segregation during lifetime in a holistic approach and to give evidence of experienced segregation of individual inhabitants. The study revealed that mobility segregation may change throughout the lifetime. There were indicated “windows of change” when forms and ranges of mobility change resulting in the change of places regularly visited and social profile of people met there. However these relations are complex.
Soviet Utopia vs. systemic transformation: Development paths of mono-functional industrial towns in Georgia
Authors: Kaczmarek-Khubnaia Julia
Published: June 2024

The article aims to compare the development paths of selected industrial mono-functional towns of Georgia, considering, in particular, the changes that occurred after the country regained independence. The spatial scope includes four monotowns of Georgia: Chiatura, Kaspi, Tkibuli and Rustavi. The time frame of the detailed analysis, based on population data, covers the period 1922–2021 (in examining the changes that occurred in Chiatura and Tkibuli, reference was also made to the period prior to Georgia’s incorporation into the Soviet Union). Based on the research conducted using the case study and desk research methods, the article presents the possible directions of development of the monotowns in Georgia, which were identified based on the assumptions of path dependency theory. In the detailed results, the characteristic features of the units were indicated, and their development paths were presented (both in the Soviet period and after 1991). The study was concluded by assigning the towns to the priorly extracted variants of the development paths after 1991 (variants A and B).
New invasion or expansion: evaluating the genetic relationships of Bactrocera dorsalis (Diptera: Tephritidae) among detections in Florida
Authors: Todd Terrance N. , Steck Gary J. , Barr Norman B.
Published: June 2024

Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), the oriental fruit fly, is a highly invasive species that has occasionally been detected in Florida, where conditions are highly favorable for the establishment of this pest. In 2015, a major infestation of B. dorsalis was detected in the Redland agricultural area of Miami-Dade county. Other detections of this pest have occurred in various locations in Florida, including the Redland area, before and after 2015. Questions arose whether any of these detections were related to the major infestation in Redland in 2015, possibly as one or more small, scattered populations that went undetected over time only to resurge as better conditions arose. To address this question, the genetic variation of the 2015 Redland outbreak was characterized using microsatellite DNA and by sequencing a portion of the mitochondrial cytochrome oxidase I (COI) gene. Population structure analyses and exclusion testing was performed on flies captured in years immediately preceding and after 2015 using microsatellites to determine (1) if flies were inconsistent with a shared source and (2) if the 2015 population could be excluded as source of subsequent captures. The COI sequences of the flies also were compared to determine if the 2015 outbreaks could explain variation in subsequent years. Results from this study found that flies captured before and after 2015 were not related to the population eradicated in Redland in 2015. Therefore, we concluded that flies captured in Florida between 2014 and 2021 were not part of any single, continuous breeding population that persisted over months.

Material–Art–Dust. Reflections on Dust Research between Art and Theory
Authors: Rauh Andreas
Published: June 2024

Dust is a distinctive material that, in addition to its physical properties, reveals anthropological and cultural dimensions, particularly within aesthetic contexts. In a collaborative project focused on “dust,” a theoretical-systematic approach is combined with an artistic-practical-participatory one. Philosophical reflections and artistic concepts related to the material “dust,” specific artworks involving dust, and the relationship between artwork and theory are interwoven. Thus, the text discusses various types of dust, the role of the artist, different modes of perception, cultural context, forms of dust and materiality, media-specific characteristics, and questions of mediation. Throughout this process, common practices of artistic and theoretical engagement are transformed and developed.

Authors: Gong Siyi , Zheng Jinguang , Yang Xin , Ma Yan , Tong Zhenfeng , Chen Tao
Published: June 2024

Radionuclide migration is an essential process in the performance and safety assessments of radioactive waste repository. This study investigates uranium migration in Beishan granite using the continuous column method, focusing on the effects of flow rate, eluent pH, and carbonate. Experimental parameters were used to perform COMSOL simulations of the migration process. The findings reveal that mechanical dispersion plays a predominant role in uranium migration in the granite column. Notably, the impact of adsorption on migration appears to be limited, likely due to the brief contact time in the experimental setup. The study successfully demonstrates the capability of COMSOL in simulating radionuclide migration, offering significant insights for the performance and safety assessments of repository.
Which has Higher Real Effects on an US Unincorporated Territory, The Price of Crude Oil or the Monetary Policy?
Authors: Rodriguez Carlos , Quintero Braulio
Published: June 2024

Puerto Rico is an unincorporated territory of the United States of America. As part of the political-economic arrangement between both political entities, Puerto Rico does not control the local price of oil because it does not have domestic sources of oil, and it does not control its monetary policy, as that is a right reserved by the U.S. Federal Reserve System.  This paper investigates the impacts of exogenous shocks of oil price and monetary policy on the Economic Activity Index, Puerto Rico Consumer Price Index, total non-farm employment, electricity consumption, gasoline consumption, and cement sales. Impulse response functions are used to study the oil price and monetary policy shocks. The oil price shock had a more significant effect on gasoline consumption than on electricity consumption. Monetary policy shocks had a higher magnitude on electricity consumption than on gasoline consumption. The monetary policy and oil price shock had minimal effect on the aggregated endogenous variables, Economic Activity Index, and Puerto Rico Consumer Price Index. This study suggests that individuals in Puerto Rico are vulnerable to a volatile oil market. Also, both exogenous variable shocks had minimal impact on employment. As for future steps, it would be prudent to investigate the effect of both exogenous variables on individual employment sectors, not aggregated. Besides, the government of Puerto Rico should develop policies to minimize the effect of oil price shocks.
Spotted Fever Group rickettsiae are the Dominant Pathogens in Parasitic Rhipicephalus microplus in Yunpan and Menghun, Xishuangbanna, Yunnan Province, China
Authors: Zhang Lin , Miao Guangqing , Hou Xuexia , Wang Peng , Guo Ying , Duan Cunjuan , Yang Xiaona , Hao Qin
Published: June 2024

Objective:

Distribution of the bacterium flora in ticks has an essential role in mapping and preventing local tick-borne diseases. The purpose of the current study was to map the bacterium flora and identify the main pathogens in ticks in grazing areas of Yunnan province.

Methods:

The V3-V4 region of 16S rRNA amplifier sequencing was used to analyze the tick-borne pathogens in Rh. Microplus. A prevalence survey on B. burgdorferi s.l., B. miyamotoi, E. chaffeensis, A. phagocytophilum, Coxiella burnetiid, and the spotted fever group rickettsiae was carried out using PCR. Phylogenetic analysis was used to identify and cluster the main prevalent microbe amplicons.

Results:

One hundred five genera and 117 species were detected in 50 ticks. Rickettsia, Anaplasma, Borrelia, Coxiella, and Ehrlichia were identified in tick samples by high-throughput sequencing at the genus level. Pathogen prevalence testing showed that the ticks were positive for B. burgdorferi s.l. (9/50 [18%]), A. phagocytophilum (1/50 [2%]), and the spotted fever group rickettsiae (35/50 [70%]), which were closely related to Candidatus R. jiangxinensis.

Conclusion:

The spotted fever group rickettsiae was the dominant pathogens in Xishuangbanna. Dual co-infection (1/50 [14%]) with Candidatus R. jiangxinensis and Borrelia garinii was demonstrated. V3-V4 high-throughput sequencing of the 16S rRNA gene was not sensitive to identify species for some bacteria, so more accurate and comprehensive analysis is necessary.
To trust or not to trust ICT? Empirical model of relation between career readiness, trust, and distrust
Authors: Kowalczyk Elzbieta , Lewicka Dagmara , Zajac Pawel
Published: June 2024

In this study, the authors focus on two issues: the influence of technology trust and distrust on career readiness and the identification of these trust and distrust factors determined by the respondent’s gender. To achieve this goal, the authors collected data using the survey method. The study was conducted among 871 Polish university students aged 18 to 25. Structural equation modeling was used to show potential causal dependencies between variables. The study provides valuable insight into research on trust and distrust in technology. Three groups of factors influencing career readiness were identified: catalysts (ICT trust, human-ICT competition), inhibitors (digital illiteracy, harmful ICT) and neutrals (ICT scepticism, digital anxiety). Variables in the career inhibitor category are not significant for the male respondents. The model used in the study indicates higher readiness among women in the dedication dimension, lower readiness in the engagement dimension, and no gender difference in the sacrifice dimension. The differential role of gender is confirmed in the context of career readiness. Limitations for this type of research are related to the difficulty of reaching the appropriate research sample, and thus its representativeness. In this case, thanks to a large research sample, it was possible to capture the relationships that allow for a better understanding of Generation Z.
Race, Time, and Architecture: Dilemmas of Africanization in Ghana, 1951–66
Authors: Stanek Łukasz
Published: June 2024

This article discusses the Africanization of architectural labor in Ghana during the late colonial and early postindependence periods (1951–66). It focuses on the state-supported emergence, advancement, and emancipation of Indigenous architects and institutions in the context of decolonization and the Cold War. Using archival materials held in Accra, Kumasi, and London, the article shows how professionals and administrators negotiated between their double obligations: to fast-track governmental development plans and to Africanize the Public Works Department and its successors. These decision makers addressed temporal dilemmas concerning recruitment, standards, allocation, and racialization of architectural labor. In so doing, they redefined both colonial-era racial categories and racialized Cold War imaginaries of who counted as an African and who counted as an Other. This study advances the architectural history of postcolonial Ghana and broadens the debate about racialization of architecture beyond North America and Western Europe.

Deagrarianization and Local Food Security Strategy for Peasant Communities in Rural Central Java
Authors: Pujiriyani Dwi Wulan , Soetarto Endriatmo , Santosa Dwi Andreas , Agusta Ivanovich
Published: June 2024

Food security is one of the important issues in the study of deagrarianization. In macro level, deagrarianization can weaken food security which is indicated by the ability of food production which continues to decline due to the structural transformation of the economy from agriculture to non-agriculture. The purpose of this study is to determine food security at the community level when the symptoms of macro deagrarianization have occurred. This research is conducted by qualitative methods. An ethnosociological approach is used by combining community case study methods and ethnographic methods. The results show that food security at the community level is still well-maintained. Deagrarianization has not diminished the ability of the community to meet their food needs. Communities have internal mechanisms that secure their food sufficiency through food strategies and non-food strategies. The food strategy is carried out through saving yields for grain stores (family food barns) and reduce the amount of consumption. Meanwhile the non-food strategy is carried out through diversification of livelihoods by relying on available extractive landscapes. Swamps (balongan) are used as a food source that provides various types of local fish, crabs and snails as a source of protein for family consumption and also for sale to local collectors.

Purpose: to determine the features of competitive activity at the 2023 continental championships in Greco-Roman wrestling. Material and methods. The analysis of scientific and methodical literature, the analysis of protocols and video recordings of competitive activities was used to solve the research tasks; expert assessment; methods of mathematical statistics. 105 matches at the 2023 continental championships were analyzed: Asian Championship (n=30 matches), European Championship (n=30 matches), Pan American Championship (n=24 matches), African Championship (n=21 matches). A total of 210 wrestlers (winners and losers), participants in the final fights (fighting for first and third places) took part in the study. In competitive activity, the following indicators were evaluated: the duration of fights (time of the fight); all technical and tactical actions carried out by wrestlers in fights (number of times); the number of non-standard situations in the rack and parterre (passives, violations of the rules, challenges); effectiveness of the applied technique in the rack and parterre (assessed in points: 1 point, 2 points, 4 points, 5 points). Results: the analysis of the fights made it possible to establish that at most continental championships, athletes performed more technical and tactical actions (TTD) in the rack than in the floor: European Championship (rack – 57,7 %; floor – 42,3 %); Asian Championship (stand – 59,8 %; floor – 40,2 %); African Championship (stand – 52,5%; floor – 47,5 %). At the Pan American Championship, athletes spent more TTD in the floor than in the rack (rack – 31,8 %; floor – 68,2 %). The highest average number of non-standard situations per scrimmage is observed at the European Championship (1,83 non-standard situation per scrimmage), then at the Asian Championship (1.80 non-standard situation per scrimmage), then at the Pan American Championship (0,92 non-standard situation per scrimmage) and African Championship (0,76 non-standard situation per scrum). The highest average performance in a scrimmage is observed at the Asian Championship (7,40 points per scrimmage), then at the European Championship (6,83 points), then at the African Championship (4,76 points) and at the Pan American Championship (4,50 points). Conclusions. An analysis of competitive activity at the 2023 continental championships in Greco-Roman wrestling was conducted. The results of the study indicate the peculiarities of each championship: a different ratio of technical and tactical actions in the racks and parterre; the difference in the average number of non-standard situations and performance in fights. The obtained results will make it possible to provide recommendations on changing the rules of competitions and increasing the spectacle of Greco-Roman wrestling.

Purpose: to investigate the novel possibilities of assessing simple visual-motor reaction using modern mobile technologies. Material and methods. Research methods included analysis and synthesis of scientific-methodical literature, psychophysiological measurements, and mathematical statistical methods utilizing licensed programs RStudio and Numbers. The study was conducted in several stages. In the first stage, 135 students from Kharkiv State Academy of Physical Culture and Kharkiv State Academy of Arts of various specializations, aged 18-23 years, participated: martial arts (n=45); sports games (n=28); sports and artistic gymnastics (n=22); dance, choreography (n=40). The second stage presented the results of measurements from over 200 respondents, of different ages and genders, users of the «Reaction Visual & Acoustical» application on the iOS platform who provided their results in the «Game Center». Results: According to the first stage findings, information regarding the characteristics of the manifestation of simple visual-motor reaction in students of various specializations was obtained. It was noted that the level of sports qualification of athletes influences the reaction manifestation level. The least changes outside the upper and lower quartiles were observed in the martial arts group, where more students had higher sports qualifications. The most significant changes outside the upper and lower quartiles were observed in the sports games group, indicating the presence of athletes of different qualification levels in this group. According to the second stage results, a comparative analysis determined that there were no statistically significant differences (p>0,05) between the measurement indicators of «Game Center» users and the indicators of students of various specializations. Comparing the measurement results in the study groups, it was found that the reaction time of martial artists was statistically lower (p<0,05) than the reaction time of representatives of other specializations and «Game Center» users. Conclusions. Modern computer technologies allow for increased accuracy and speed of obtaining results of various measurements, saving time on result processing, making operational conclusions, and making relevant decisions. The results obtained during the study indicate that the level of sports qualification of athletes influences the reaction manifestation level. Thus, it was determined that martial artists with higher sports qualifications, who passed the appropriate selection stages, have more developed psychophysiological capabilities for the manifestation of various types of reactions. According to the comparative analysis results, it can be argued that there are no statistically significant differences (p>0,05) between the measurement indicators of «Game Center» users and the indicators of students of various specializations.
