Published: August 2024

Lembongan Island and Perancak are two areas located in Bali Province that have mangrove ecosystems that are utilized as ecotourism areas with different geomorphologies. This study was conducted with the aim to determine the density and spatial distribution of gastropods and their relationship with environmental characteristics using a multivariate analysis approach i.e., Correspondence Analysis (CA) and Principal Component Analysis (PCA). Sampling used a purposive sampling method consisting of 3 zones based on distance from the sea, namely the sea, middle and land zones. The results showed that the most gastropod species in Lembongan Island were found in the sea zone with 17 which the most gastropod species is Pyrene ocellata, while in Perancak the most gastropod species were found in the middle zone with 13 which the most gastropod species is Sphaerasiminea miniata. Environmental characteristics such as temperature, pH, ORP, salinity and dissolved oxygen still support the survival of gastropods. There is twelve mangrove species have found, were Rhizopora stylosa, Rhizopora apiculata, Rhizopora mucronata, Rhizopora lamarckii, Bruguiera gymnorrhiza, Ceriops tagal, Avicennia marina, Avicennia alba, Avicennia rumphiana, Avicennia officinalis, Sonneratia alba, and Xylocarpus granatum.
O Livro Didático de Português ao longo do tempo: mais do mesmo
Authors: Malheiros Santana Andreia da Cunha , Michelato João Pedro Buzinello 
Published: August 2024

Este artigo propõe uma reflexão sobre o ensino de língua portuguesa ao longo do tempo, ele é fruto de uma pesquisa cujo objetivo principal foi comparar dois livros didáticos destinados ao ensino da disciplina escolar de Português, para o oitavo ano do ensino fundamental: um livro didático de 1969 e outro, de 2018. Para realizar esta comparação foi escolhido o tema “formação de palavras”, tópico que se manteve nos dois materiais. A metodologia empregada foi de natureza qualitativa. A análise dos dados teve como aporte teórico diferentes estudos, entre eles os que envolvem livro didático, realizados por Bunzen (2000; 2001) e Bräkling (2014) e os que envolvem a epilinguística, cujos teóricos se alternam entre Franchi (1991), Wamser (2013) e Wamser e Rezende (2014; 2019). A partir da articulação destes estudiosos, foi possível compreender um pouco do processo de ensino-aprendizagem através do tempo. Os resultados obtidos apontam algumas mudanças, mas também algumas permanências. Foi possível identificar mais flexibilidade dos exercícios, mais interação com os alunos e uma tentativa de atrelar o estudo da gramática ao texto, no entanto, apesar destas alterações, o livro didático carrega ainda uma metodologia transmissiva do conhecimento, baseado na metalinguística e com pouca reflexão pragmática ; o texto, embora presente no tópico, aparece como um pretexto para exemplificar a gramática.
Photon-count fluctuations of spontaneous parametric down conversion exhibit long-range correlations
Authors: Tey Lian Seng , Muniandy S. V. , Chong Wu Yi 
Published: August 2024

We investigate the fluctuation dynamics of photons generated by spontaneous parametric down conversion (SPDC) using detrended fluctuation analysis (DFA). SPDC photon pairs were generated via a periodically poled potassium titanyl phosphate waveguide, pumped by a 405 nm continuous-wave laser. The scaling exponents obtained from DFA reveal that SPDC photons exhibit long-range correlations at high pump power regimes. The average scaling exponent of DFA increases from 0.67 to 0.97 as the laser diode drive current increases, indicating the existence of long-range correlations. Our analysis concluded that the scaling exponent of aggregated time series is correlated to the number of SPDC photon pairs.
Vortex beam assisted generation and manipulation of structured light
Authors: Mallick Nawaz Sarif 
Published: August 2024

We conduct theoretical investigations into a fundamental closed-loop Λ-type atomic system using 87Rb atoms, aiming to efficiently generate and manipulate structured light beams. A phase-singular microwave (MW) beam with a topological charge l
μ
and a phase-singular optical probe beam with a topological charge l
p
collectively induce phase-dependent atomic coherence, resulting in periodic oscillations of probe absorption in the transverse plane. The number of absorption or transparency windows in the transverse plane is determined by the resultant topological charge of the system, denoted as l=l
μ
−l
p
. We investigate the propagation of a paraxial doughnut-shaped probe beam through the phase-dependent atomic medium and showcase the generation of petal-like structured beams for various combinations of l
μ
and l
p
. We provide a detailed theoretical explanation of these results using the analytical expression of probe susceptibility. We outline how this scheme effectively serves as a sensor adept at discerning particular OAM modes. This selective detection capability is valuable in scenarios where only certain OAM states carry relevant information. The relative phase between the interacting fields can be used to rotate the structured probe beam by 360 deg in the clockwise or counterclockwise direction. This manipulation of spatial position of different OAM modes can be employed in implementing OAM-based logical operations.

Published: August 2024

Background
Leprosy affects various organs in addition to skin, eyes, and peripheral nerves. Testicular involvement in leprosy patients is common and causes disturbance in endocrine function of the testis and results in hypogonadism. Hypogonadism is frequently undiagnosed and underreported.

Objective
This study aimed to assess hypogonadism and associated factors among leprosy patients at Alert Comprehensive Specialized Hospital, Ethiopia.

Methods
A cross-sectional study design was used in which consecutive 146 male leprosy patients aged between 18 to 65 years attending outpatient follow-up at leprosy outpatient clinic were included. Data was gathered both from patient charts and through patients’ interviews. Androgen deficiency symptoms were assessed by androgen deficiency in the aging male questionnaire, and 5ml of blood samples were taken from study participants and serum total testosterone, LH, and FSH were analyzed by Electrochemiluminescence method. Statistical correlation was assessed by Spearman correlation. A multivariable binary logistic regression model was used to identify the independent factors associated with hypogonadism and P-value <0.05 was used to declare statistical significance.

Results
The prevalence of hypogonadism was 39 (26.7%). Out of this, 34 (87.2%) had primary hypogonadism, whereas 5 (12.8%) had secondary hypogonadism. Total testosterone was inversely correlated with Body mass index (r = -0.37, p = 0.002), Luteinizing hormone (r = -0.43, p <0.001), and Follicular stimulating hormone (r = -0.42, p< 0.001). However, Total testosterone was not significantly correlated with age (r = -0.019, p = 0.81). BMI [AOR = 1.32, 95%CI (1.16–1.51)] and grade-II disability [AOR = 3.80, 95%CI (1.23–11.64)] were identified as independent risk factors for hypogonadism.

Conclusion
Nearly one-fourth of male leprosy patients had hypogonadism. Overweight and grade-II disability were independent risk factors for hypogonadism.

Published: August 2024

Background
To monitor the progress of lymphatic filariasis (LF) elimination programmes, field surveys to assess filarial antigen (Ag) prevalence require access to reliable, user-friendly rapid diagnostic tests. We aimed to evaluate the performance of the new Q Filariasis Antigen Test (QFAT) with the currently recommended Filariasis Test Strip (FTS) for detecting the Ag of Wuchereria bancrofti, the causative agent of LF, under field laboratory conditions.

Methodology/Principal findings
During an LF survey in Samoa, 344 finger-prick blood samples were tested using FTS and QFAT. Microfilariae (Mf) status was determined from blood slides prepared from any sample that reported Ag-positive by either Ag-test. Each test was re-read at 1 hour and the next day to determine the stability of results over time. Overall Ag-positivity by FTS was 29.0% and 30.2% by QFAT. Concordance between the two tests was 93.6% (kappa = 0.85). Of the 101 Mf slides available, 39.6% were Mf-positive, and all were Ag-positive by both tests. Darker test line intensities from Ag-positive FTS were found to predict Mf-positivity (compared to same/lighter line intensities). QFAT had significantly higher reported test result changes than FTS, mostly reported the next day, but fewer changes were reported between 10 minutes to 1hour. The field laboratory team preferred QFAT over FTS due to the smaller blood volume required, better usability, and easier readability.

Conclusion/Significance
QFAT could be a suitable and user-friendly diagnostic alternative for use in the monitoring and surveillance of LF in field surveys based on its similar performance to FTS under field laboratory conditions.
Fallacy of attributing the U.S. firearm mortality epidemic to mental health
Authors: Bleyer Archie , Siegel Stuart E. , Estrada Jaime , Thomas Charles R. 
Published: August 2024

Background
Annual global data on mental disorders prevalence and firearm death rates for 2000–2019, enables the U.S. to be compared with comparable counties for these metrics.

Methods
The Institute for Health Metrics and Evaluation (IHME) Global Health Burden data were used to compare the prevalence of mental disorders with overall, homicide and suicide firearm death rates including homicides and suicides, in high sociodemographic (SDI) countries.

Results
Overall and in none of the nine major categories of mental disorders did the U.S. have a statistically-significant higher rate than any of 40 other high SDI countries during 2019, the last year of available data. During the same year, the U.S. had a statistically-significant higher rate of all deaths, homicides, and suicides by firearm (all p<<0.001) than all other 40 high SDI countries. Suicides accounted for most of the firearm death rate differences between the U.S. and other high SDI countries, and yet the prevalence of mental health disorders associated with suicide were not significantly difference between the U.S. and other high SDI countries.

Conclusion
Mental disorder prevalence in the U.S. is similar in all major categories to its 40 comparable sociodemographic countries, including mental health disorders primarily associated with suicide. It cannot therefore explain the country’s strikingly higher firearm death rate, including suicide. Reducing firearm prevalence, which is correlated with the country’s firearm death rate, is a logical solution that has been applied by other countries.

An optimal transport approach to estimating causal effects via nonlinear difference-in-differences
Authors: Torous William , Gunsilius Florian , Rigollet Philippe 
Published: August 2024

Abstract
We propose a nonlinear difference-in-differences (DiD) method to estimate multivariate counterfactual distributions in classical treatment and control study designs with observational data. Our approach sheds a new light on existing approaches like the changes-in-changes estimator and the classical semiparametric DiD estimator, and it also generalizes them to settings with multivariate heterogeneity in the outcomes. The main benefit of this extension is that it allows for arbitrary dependence between the coordinates of vector potential outcomes and includes higher-dimensional unobservables, something that existing methods cannot provide in general. We demonstrate its utility on both synthetic and real data. In particular, we revisit the classical Card & Krueger dataset, which reports fast food restaurant employment before and after a minimum wage increase. A reanalysis with our methodology suggests that these restaurants substitute full-time labor with part-time labor on aggregate in response to a minimum wage increase. This treatment effect requires estimation of the multivariate counterfactual distribution, an object beyond the scope of classical causal estimators previously applied to this data.

Published: August 2024

Проведено комплексное палеоэкологическое изучение многолетнемерзлых торфяных отложений из трех местонахождений среднего течения р. Юрибей в подзоне современных субарктических кустарниковых тундр п-ова Ямал. На основе результатов палинологического и карпологического методов и данных радиоуглеродного датирования реконструированы изменения региональной, локальной растительности и климатических условий Центрального Ямала в поздне- и послеледниковый периоды. Установлено, что в позднем дриасе, около 12,6–11,7 тыс. кал. л. н., на данной территории в климатических условиях, близких к современным, были распространены кустарниковые тундры с Betula nana. Около10,2–9,7 тыс. кал. л. н. в раннеголоценовое потепление в связи с улучшением климатических условий началось проникновение древесных пород(Betula sect. Betula, Picea obovata, Larix sibirica) и сопутствующих им бореальных травянистых растений. Наиболее благоприятные условия для произрастания березы древовидной формы, лиственницы и ели на территории Центрального Ямала существовали в раннем и среднем голоцене в интервале 10,2–4,4 тыс. кал. л. н. В это время были распространены редколесья или даже сомкнутые леса, климат был значительно теплее современного. В конце среднего голоцена(4,5–4,4 тыс. кал. л. н.) лесная растительность деградировала, сформировались открытые ландшафты с тундровыми сообществами. Климатические условия стали близки к современным.
A comprehensive paleoecological study of permafrost peat deposits from three locations of the middle reaches of the Yuribey River in the subzone of modern subarctic shrub tundra of the Yamal Peninsula has been carried out. Based on the results of palynological and carpological methods and radiocarbon dating data, the changes in regional and local vegetation and climatic conditions of Central Yamal in the Late Glacial and Postglacial periods are reconstructed. It was found that in this area shrubby tundra with Betula nana were widespread in climatic conditions close to modern ones in the Younger Dryas about 12.6–11.7 cal. ka BP. The penetration of tree species (Betulasect. Betula, Picea obovata, Larix sibirica) and their accompanying boreal herbaceous plants began due to improved climatic conditions in the Early Holocene warming about 10.2–9.7 cal. ka BP. The most favorable conditions for the growth of tree–shaped birch, larch and spruce in the territory of Central Yamal existed in the Early and Middle Holocene in the range of 10.2–4.4 cal. ka BP. At that time, sparse woodlands or even closed forests were common, the climate was much warmer than the modern one. Forest vegetation degraded and open landscapes with tundra communities formed at the end of the Middle Holocene (4.5–4.4 cal. ka BP). The climatic conditions have become close to modern ones.
Vital structure of population Larix gmelinii in urban environment
Authors: Морозова Г.Ю. 
Published: August 2024

Рассмотрены вопросы изменения жизненного состояния Larix gmelinii по градиенту урбанизированных экотопов на основе популяционного анализа и морфометрического подхода. L. gmelinii, произрастающая в разных условиях, отличалась по ряду размерных и ростовых характеристик и показателям фотосинтетической деятельности. Максимальные значения отмечены у растений, произрастающих в скверах и на городских улицах в условиях высокой инсоляции. Популяционный анализ в отношении L. gmelinii в урбанизированной среде был проведен на основе количественных параметров, которые характеризовали рост и формообразование растений (величина ежегодного прироста, показатели фотосинтетической активности). Детерминирующий комплекс признаков для виталитетного анализа L. gmelinii составили биологически значимые признаки с высокой степенью изменчивости: длина прироста побега (СV варьировал от39,09 до 68,86 %), масса хвои на годичном приросте (СV51,81–120,52 %), масса годичного побега (СV67,73–119,85 %). Виталитетная структура популяций растений закономерно и статистически достоверно изменялась в зависимости от онтогенетического состояния, уровня устойчивости растений к антропогенным нагрузкам. Виталитетная структура популяций вида в вегетативном онтогенетическом состоянии изменялась от депрессивной до равновесной, индекс качества популяций увеличивался от0,2 до 0,333. При обследовании озеленения транспортных магистралей города локальные популяции L. gme­linii в генеративном онтогенетическом состоянии были процветающего типа, индекс качества популяций варьировал незначительно – от0,47 до 0,49. Пластичность вида, высокая жизнеспособность L. gmelinii, обусловленная устойчивостью к загрязнению воздуха и неприхотливостью к почвенным условиям, позволяют широко использовать лиственницу для озеленения городских территорий.
The questions of changes in the life status of Larix gmelinii along the gradient of urbanized ecotypes are considered on the basis of population analysis and morphometric approach. L. gmelinii growing under different conditions differed in a number of size and growth characteristics of photosynthetic activity. The maximum values were noted in plants growing in public gardens and on city streets under conditions of high insolation. The vitality structure of the populations of the species in the vegetative ontogenetic state changed from depressive to equilibrium, the population quality index changed from 0.2 to 0.333. When examining the landscaping of transport highways of the city, local populations of L. gmeliniiin the generative ontogenetic state were of a prosperous type, the population quality index varied slightly from 0.47 to 0.49. The plasticity of the species, the high viability of L. gmelinii, due to resistance to air pollution, unpretentiousness to soil conditions of growth, transplantation, allow larch to be widely used for landscaping urban areas.
