Abstract

A sizable fraction of the heavy elements synthesized by stars in galaxies condenses into sub-micron-sized solid-state particles, known as dust grains^1, 2. Dust produces a wavelength-dependent attenuation, Aλ, of the galaxy emission, thereby significantly altering its observed properties^3. Locally, Aλ is in general the sum of a power-law and a UV feature (’bump’)^4 produced by small, carbon-based grains^5. However, scant information exists regarding its evolution across cosmic time. Here, leveraging data from 173 galaxies observed by the James Webb Space Telescope in the redshift range z = 2 − 12^6, we report the most distant detection of the UV bump in a z ∼ 7.55 galaxy (when the Universe was only ∼ 700 Myr old), and show for the first time that the power-law slope and the bump strength decrease towards high redshifts. We propose that the flat Aλ shape at early epochs is produced by large grains newly formed in supernova ejecta^7, which act as the main dust factories at such early epochs. Importantly, these grains have undergone minimal reprocessing in the interstellar medium due to the limited available cosmic time^8. This discovery opens new perspectives in the study of cosmic dust origin and evolution.

Abstract

Phylogeographic studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of recent history and current landscape, we need to evaluate fine scale patterns of genetic diversity in relation to detailed environmental information. We investigated the phylogeography and demographic history of three understory bird species, Oneillornis salvini, Willisornis poecilonotus, and Lepidothrix coronata, from the Purus-Madeira interfluvium, within the Inambari area of endemism using one mtDNA and two nuclear markers with dense sampling. All species showed signs of recent population expansion and had no genetic structure within the interfluvium, which includes distinct ecoregions and geological formations. This result is likely due to a dynamic geological history and recent occupation of the landscape by current populations and suggests that biogeographic history is a better predictor of bird genetic diversity within the Purus-Madeira interfluvium than the current environmental heterogeneity. The pavement of the BR-319 road is of great concern in this scenario, since this anthropogenic barrier will isolate connected populations, well beyond its potential drive of habitat loss and fragmentation.
Multi-timescale exploration of teleconnection/tornado activity relationships in the Southeastern United States
Authors: Moore Todd W. , DeBoer Tiffany A. , Fricker Tyler 
Published: February 2024

Abstract
Teleconnections like the El Niño/Southern Oscillation affect climate and weather conditions across the globe, including conditions that modulate tornado activity. Early studies of teleconnection/tornado activity relationships provided evidence of links between one teleconnection and tornado activity. Later attempts introduced multivariate approaches by analyzing bivariate distributions and integrating multiple teleconnections in statistical models to predict variability in tornado activity. However, little attention has been given to teleconnection interactions and the role of these interactions in modulating tornado activity. Here, we employ a data-driven, multiple logistic regression modelling approach to explore the interactions between the El Niño/Southern Oscillation, North Atlantic Oscillation, Artic Oscillation, and Pacific North American pattern and their ability to predict the odds of an active tornado period in the southeastern United States. We develop models at the annual, seasonal, and monthly scales and, in doing so, illustrate that the teleconnections and teleconnection interactions that best predict the odds of an active tornado period differ across timescales and that the relationships exhibit clear seasonality. We also show climate conditions associated with select interactions that help explain the elevated tornado activity, namely anomalously high near-surface air temperature and humidity steered by an anomalously strong subtropical high.

Abstract

Bacterial communities in drinking water provide a gauge to measure quality and confer insights into public health. In contrast to urban systems, water treatment in rural areas is not adequately monitored and could become a health risk. We performed 16S rRNA amplicon sequencing to analyze the microbiome present in the water treatment plants at two rural communities, one city, and the downstream water for human consumption in schools and reservoirs in the Andean highlands of Ecuador. We tested the effect of water treatment on the diversity and composition of bacterial communities. A set of physicochemical variables in the sampled water was evaluated and correlated with the structure of the observed bacterial communities. Predominant bacteria in the analyzed communities belonged to Proteobacteria and Actinobacteria. The Sphingobium genus, a chlorine resistance group, was particularly abundant. Of health concern in drinking water reservoirs were Fusobacteriaceae, Lachnospiraceae, and Ruminococcaceae; these families are associated with human and poultry fecal contamination. We propose the latter families as relevant biomarkers for establishing local standards for the monitoring of potable water systems in highlands of Ecuador. Our assessment of bacterial community composition in water systems in the Ecuadorian highlands provides a technical background to inform management decisions.
Statistical evaluation of trends of water quality monitoring parameters relevant to cyanobacterial blooms in the urban tropical reservoir

Published: February 2024

Abstract

The accelerated growth of cyanobacteria in water bodies is a global critical environmental issue caused by continuous discharges of effluents into the environment that are rich in phosphorus and nitrogen. So, cyanobacteria have found propitious conditions for proliferation, provoking significant ecological imbalances. Cyanobacteria produce cyanotoxins, which are harmful to life, and compounds like 2-methylisoborneol and geosmin that affect water's taste and odor. This study analyzed a long-term database of important environmental parameters from a tropical reservoir in São Paulo State, Brazil. The statistical methods of correlation matrices and principal component analysis were used. Data analysis revealed a significant relationship between cyanobacteria growth and high levels of phosphate and nitrogen. Furthermore, positive correlations were found among concentrations of biocidal elements like antimony, arsenic, and selenium related to cyanobacterial bloomings. These correlations can be attributed to agricultural wastewaters and/or possible algicide used to control these microorganisms.

Published: February 2024

Background
Previous studies have confirmed the separate effect of arterial stiffness and obesity on type 2 diabetes; however, the joint effect of arterial stiffness and obesity on diabetes onset remains unclear.

Objective
This study aimed to propose the concept of arterial stiffness obesity phenotype and explore the risk stratification capacity for diabetes.

Methods
This longitudinal cohort study used baseline data of 12,298 participants from Beijing Xiaotangshan Examination Center between 2008 and 2013 and then annually followed them until incident diabetes or 2019. BMI (waist circumference) and brachial-ankle pulse wave velocity were measured to define arterial stiffness abdominal obesity phenotype. The Cox proportional hazard model was used to estimate the hazard ratio (HR) and 95% CI.

Results
Of the 12,298 participants, the mean baseline age was 51.2 (SD 13.6) years, and 8448 (68.7%) were male. After a median follow-up of 5.0 (IQR 2.0-8.0) years, 1240 (10.1%) participants developed diabetes. Compared with the ideal vascular function and nonobese group, the highest risk of diabetes was observed in the elevated arterial stiffness and obese group (HR 1.94, 95% CI 1.60-2.35). Those with exclusive arterial stiffness or obesity exhibited a similar risk of diabetes, and the adjusted HRs were 1.63 (95% CI 1.37-1.94) and 1.64 (95% CI 1.32-2.04), respectively. Consistent results were observed in multiple sensitivity analyses, among subgroups of age and fasting glucose level, and alternatively using arterial stiffness abdominal obesity phenotype.

Conclusions
This study proposed the concept of arterial stiffness abdominal obesity phenotype, which could improve the risk stratification and management of diabetes. The clinical significance of arterial stiffness abdominal obesity phenotype needs further validation for other cardiometabolic disorders.

Authors: Han Jae Sang , Lim Ji Hyung , Kim Yeonji , Aliyeva Aynur , Seo Jae-Hyun , Lee Jaehyuk , Park Shi Nae 
Published: February 2024

Abstract

Background
Hearing rehabilitation with auditory training (AT) is necessary to improve speech perception ability in patients with hearing loss. However, face-to-face AT has not been widely implemented due to its high cost and personnel requirements. Therefore, there is a need for the development of a patient-friendly, mobile-based AT program.

Objective
In this study, we evaluated the effectiveness of hearing rehabilitation with our chat-based mobile AT (CMAT) program for speech perception performance among experienced hearing aid (HA) users.

Methods
A total of 42 adult patients with hearing loss who had worn bilateral HAs for more than 3 months were enrolled and randomly allocated to the AT or control group. In the AT group, CMAT was performed for 30 minutes a day for 2 months, while no intervention was provided in the control group. During the study, 2 patients from the AT group and 1 patient from the control group dropped out. At 0-, 1- and 2-month visits, results of hearing tests and speech perception tests, compliance, and questionnaires were prospectively collected and compared in the 2 groups.

Results
The AT group (n=19) showed better improvement in word and sentence perception tests compared to the control group (n=20; P=.04 and P=.03, respectively), while no significant difference was observed in phoneme and consonant perception tests (both P>.05). All participants were able to use CMAT without any difficulties, and 85% (17/20) of the AT group completed required training sessions. There were no changes in time or completion rate between the first and the second month of AT. No significant difference was observed between the 2 groups in questionnaire surveys.

Conclusions
After using the CMAT program, word and sentence perception performance was significantly improved in experienced HA users. In addition, CMAT showed high compliance and adherence over the 2-month study period. Further investigations are needed to validate long-term efficacy in a larger population.
Problems of Russian Theatrical Reception of Shakespeare in Criticism of Yuli Eichenwald
Authors: Serdechnaya V. V. , Zhatkin D. N. 
Published: February 2024

The problem of this study lies in evaluating the methodological approach of Yuli Eichenwald (1872—1928) as a theatrical critic and theorist, specifically his writings on Shakespearean productions both in Russia and abroad. Known primarily as a literary critic, Eichenwald also wrote about theater, but his works in this area have been largely unexplored. The aim of this study is to shed light on Eichenwald's principles of theatrical criticism. The material used consists of little-known articles by Eichenwald on theater theory and Shakespearean productions from 1903 to 1927. The research employs hermeneutic and comparative methods. The findings reveal that Eichenwald demonstrates a literature-centric position in his articles on theater, according to which theater is merely an illustration of literary works. He increasingly uses productions as a pretext to discuss Shakespeare, often without mentioning the actors or directors. Eichenwald’s perception of theater as a mediator, as an auxiliary device between the play and the reader, leads to his rejection of the concept of directorial theater and the denial of the director as the author of the production. The authors conclude that Eichenwald’s theatrical criticism is a logical outcome of literature-centric judgments about theater, from Aristotle to Hegel, where theater is considered as part of literature.
Category of Addressee in New Apostolic Prayer: Categorical-Textual and Axiological Aspects
Authors: Keler A. I. 
Published: February 2024

The study examines the realization of the addressee category in Protestant — New Apostolic prayers. The object of analysis is prayer as a genre of religious functional style, and the subject is the addressee category. The aim of the work is to describe the ways of explication of the addressee category in a corpus of 220 public prayers of New Apostolic Christians. The textual material was collected through participant observation and consists of transcribed audio recordings of prayers — non-reproducible texts spontaneously created by both churchgoers and clergy in various communicative situations, both religious and non-religious. The methodology of constructing thematic nomination chains is applied on a categorical-textual basis to describe the addressee category. It has been revealed that the addressee is denoted using personal pronouns ‘we’, possessive pronoun ‘our’, and nouns ‘community’, ‘brothers and sisters’, ‘children’, ‘sinners’. The results of the analysis show that these nominations are included in positively colored contexts, including the nomination ‘sinners’, which is conditioned by the specificity of the doctrine: the praying individuals are focused not on repentance but on gratitude for forgiveness. The listed ways of nominating the addressee and the description of evaluative contexts allow us to conclude about the reflection of ‘we axiological’ in the texts of New Apostolic Christians.
Leisure and Festive Activities in Russian Army on Frontlines of World War I
Authors: Kanischev V. V. , Pluzhnikov A. N. 
Published: February 2024

The need to restore lost data on the last major war of the Russian Empire implies a comprehensive coverage of events during those years, including their non-combat component. Based on the study of the “Journals of Military Actions” of combat units, which reflect little-researched stories of non-combat realities of front-line life, the authors offer a new perspective on the military everyday life of the Russian Imperial Army. The article focuses on the “pleasant” and unexpected nuances of the daily lives of soldiers and officers during the difficult years of war. Researchers have turned to such facts of military reality during the specified period as the organization of the award procedure for the command staff and lower ranks, the organization of prayers as integral components of festive events, the conduct of state (imperial) and religious holidays, as well as recreational activities. This work provides an opportunity to obtain an objective understanding of the multifaceted life and everyday life of people in wartime conditions: when circumstances allowed, performances, games, and sports events were organized and held. Without theoretical knowledge in the field of psychology and stress management techniques, the command of the Russian army organized and encouraged activities aimed at alleviating the negative consequences of combat stress.
Pilgrimage to Holy Places in History of Vyatka Province (Second Half of 19th — Early 20th Centuries)
Authors: Polovnikova M. Yu. , Nemchaninova E. N. 
Published: February 2024

The article analyzes the reasons for the growing interest in holy places, primarily Palestine, associated with Russia’s state policy, based on published sources. It also examines the forms and methods of educational work. In 1894, the Vyatka department of the Imperial Orthodox Palestinian Society was established in the Vyatka province to disseminate information about the Holy Land and support Russia’s activities in the Middle East. The department raised funds for the society’s work in the Holy Land and organized lectures on the history and activities of the society. Significant results were achieved through this educational work, including an increase in the number of members in the Vyatka department, particularly at the turn of the 19th and 20th centuries, and a growing interest in the Holy Land. Additionally, in the second half of the 19th century, some representatives of secular and spiritual society in the Vyatka province visited Orthodox holy sites, primarily the Holy Land and Mount Athos, and left memoirs about their pilgrimage experiences. Thus, the remote Vyatka province became spiritually closer to the Holy Land in the second half of the 19th century.
Genre of Discours de réception: Marguerite Yourcenar’s Speech upon her Election to French Academy and Gender Turn
Authors: Vikulova L. G. , Korolenko O. I. , Tkachenko Yu. G. 
Published: February 2024

This article analyzes the inaugural speech (discours de réception) delivered in 1981 by Marguerite Yourcenar, the first female writer elected as a member of the French Academy. Since the 17th century, such speeches have been mandatory for newly elected academicians, serving as a communicative product of academic speech practice. The study notes that commemorative speeches in honor of deceased members of the academy typically involve the use of praise as an evaluative strategy. Following the genre’s requirements, Marguerite Yourcenar addresses the conceptual space of “the value of literary heritage” of Roger Caillois, whose “academic chair” she was about to occupy as a new academician. In his work, she identifies authorial conceptual metaphors (such as “life is a game”: vie — jeu) that align with her own value system, confirming this alignment with examples from her own books or life experience. The article highlights authorial conceptual oppositions, including men — women (homes / femmes), friendship — hatred (amitié / haine), and life — death (vie / mort). As a newly elected academician, Marguerite Yourcenar perceives the French Academy as a scientific institution with both merits (Académie — science, littérature, connaissance) and shortcomings (Académie — préjugés, archaїsme), reflecting her personal position as well as her gender and social identity.
Infanticide: A Survival Strategy among the Gweno People during the Early Colonial Period in Tanganyika
Authors: Abrahamu Hosiana 
Published: February 2024

Abstract
Traditions and customs carry socio-cultural and economic values of the community where they are practised. Infanticide was a traditional practice among the Gweno people in Kilimanjaro, northern Tanzania. This practice had socio-cultural, political, and economic significance which persisted. As a global phenomenon, infanticide has attracted enormous scholarship from different disciplines covering mostly its practice, its associated beliefs, and its eradication campaigns. Despite the popularity of infanticide practices among the Gweno people, particularly during the early colonial period, little has been revealed and documented on how it was practised, associated beliefs and the socio-cultural, political, and economic significance it carried in this community. Benefitting from research findings collected in 2015 through historical and ethnological methods such as oral traditions, interviews, archival materials, and anthropological accounts, this paper uncovers the socio-cultural, political, and economic grounds of infanticide practices among the Gweno people. The paper is built on the argument that infanticide practices served as cultural, socio-political, and economic survival strategy of the Gweno people.
A 1-dimensional-two-layer transient drift-flux model for hydraulic transport pipelines: modelling and experiments of bed layer erosion and density wave amplification
Authors: de Hoog Edwin , van der Voort Tjalie , Talmon Arno , van Rhee Cees 
Published: February 2024

Abstract
Hydraulic transport pipelines in the dredging, mining and deep sea mining are designed using steady-state methods. However, these methods cannot predict density wave formation. Density waves form a risk for pipeline blockages, therefore there is a need to understand and preferably be able to model the process. The density waves studied in this research are caused by a stationary sediment deposit in the pipeline. This article explores the development of a new transient design model, based on 1-dimensional-two-layer Driftflux CFD. The two layers model the exchange of sediment between the turbulent suspension, and a stationary bed layer, and can therefore model density wave amplification. An empirical erosion-sedimentation closure relationship is applied to model the sediment exchange between the two layers, and is calibrated using experiments. The final model is also validated against a second experiment, specifically for density wave amplification. The experiments and the model show good agreement on the erosion of a stationary bed layer and the growth rate of a density wave and the amplitude of the density wave.
