В статье представлен генетический полиморфизм 16 микросателлитных маркеров у оленей эвенской породы горно-таежной зоны Якутии. Для изучения генетической структуры были использованы микросателлитные маркеры Rt6, BMS1788, Rt 30, Rt1, Rt9, FCB193, Rt7, BMS745, C 143, Rt24, OheQ, C217, C32, NVHRT16, T40, C276. Объектом исследования послужили домашние северные олени эвенской породы в количестве 178 голов. В ходе исследования установлено, что олени, разводимые ФГУП «Ючюгейское», имеют высокое генетическое разнообразие. Всего было идентифицировано 122 алелля и в среднем на локус приходилось 7,625 аллеля. Наибольшее аллельное разнообразие установлено в локусах BMS2088 и OheQ 14 и 12 соответственно, а минимальное количество - в локусах C143 и C2188 по 2 аллеля. При этом, в локусе BMS2088 число аллелей, имеющих частоту встречаемости выше 5%, составила 4, а число эффективных аллелей 3,519. Индекс фиксации принимал положительное значение в 7 локусах из 16: BMS2088, Rt1, Rt9, Rt7, OheQ, RT24 и NVHRT16 и варьировал в пределах от 0,005 до 0,054. Индекс фиксации в 9 локусах имеет отрицательное значение и колеблется от -0,004 (RT30) до -0,204 (C143). В среднем по породе индекс фиксации (F) составил -0,021, что указывает на избыток гетерозиготных особей. Наблюдаемый уровень гетерозиготности в среднем по всем локусам (Ho) составил 0,688, ожидаемая (He) 0,680, Но>He - система случайного скрещивания преобладает над инбридингом.
The article presents the polymorphism of 16 microsatellite markers in reindeer of the Evenskaya breed in the mountain taiga zone of Yakutia. To study the genetic structure, microsatellite markers Rt6, BMS1788, Rt 30, Rt1, Rt9, FCB193, Rt7, BMS745, C 143, Rt24, OheQ, C217, C32, NVHRT16, T40, C276 were used. The object of the study was 178 reindeer of Evenskaya breed. In the course of research it was found that deer bred by the FSUE "Yuchugeyskoe" have a high genetic diversity. A total of 122 alleles were identified and, on average, 7.625 alleles per locus. The greatest number of alleles was found at the BMS2088 (14) and OheQ (12) loci, and the minimum number of alleles (2) was found at the C143 C2188 loci. At locus BMS2088, the number of alleles with a frequency of occurrence above 5% was 4, and the number of effective alleles was 3.519. The fixation index takes a positive value at 7 loci of 16: BMS2088, Rt1, Rt9, Rt7, OheQ, RT24 and NVHRT16 and varies from 0.005 to 0.054. The fixation index at 9 loci is negative and ranges from -0.004 (RT 30) to -0.204 (C 143). The average fixation index (F) for the breed was -0.021, which indicates an excess of heterozygous individuals. The observed heterozygosity (Ho) is 0.688, the expected (He) 0.680, Ho> He - the system of random crossing prevails over inbreeding.

В статье представлена генетическая характеристика черно-пестрой породы крупного рогатого скота на основе микросателлитного анализа по 15 локусам: BM 1818, BM 1824, BM 2113, CSRM 60, CSSM 66, ETH 3, ETH 10, ETH 225, ILST 6, INRA 023, SPS 115, TGLA 53, TGLA 122, TGLA 126, TGLA 227. Были рассчитаны частоты аллелей, наблюдаемая, ожидаемая геретозиготности локусных микросателлитов и индекс фиксации, характеризующий нехватку или избыток гетерозигот. Результаты ДНК исследования биологического материала 56 племенных животных черно-пестрой породы показали в 15 локусах наличие 116 аллелей. Длины аллелей находились в диапазоне от 81 до 296 bp. В локусах идентифицировано от 5 до 15 аллелей. Среднее число аллелей на локус составляло 7,7, среднее число информативных аллелей - 4,7. Пять микросателлитных локусов ВМ 1818, ВМ 1824, ILST 6, SPS 115 и TGLA 126 имели минимальный набор аллелей. Максимальное число аллелей - 15 - наблюдали в локусе TGLA53. Частоты часто встречающихся аллелей в локусах с пятью аллелями составляли 0,339 - 0,580, при этом наибольшая частота наблюдалась у аллеля 248 в локусе SPS 115. В локусе TGLA53 аллель 162 отличался наибольшей встречаемостью, равной 0,226. Средний уровень фактической и ожидаемой гетерозиготности составлял 0,757 и 0,738 соответственно, а индекс фиксации минус 0,031. Следовательно, исследуемое стадо черно-пестрой породы характеризовалось незначительным избытком гетерозигот и умеренной степенью гетерозиготности.
The article presents the genetic characteristics of the black-and-white cattle breed based on microsatellite analysis of 15 loci: BM 1818, BM 1824, BM 2113, CSRM 60, CSSM 66, ETH 3, ETH 10, ETH 225, ILST 6, INRA 023, SPS 115, TGLA 53, TGLA 122, TGLA 126, TGLA 227. The allele frequencies, the observed, expected gertozygosity of local microsatellites and the fixation index characterizing the lack or excess of heterozygotes were calculated. The results of DNA testing of biological material of 56 breeding animals of the Black-and-White breed showed the presence of 116 alleles in 15 loci. Allele lengths ranged from 81 to 296 bp. At the loci, from 5 to 15 alleles were identified. The average number of alleles per locus was 7.7, the average number of informative alleles was 4.7. Five microsatellite loci BM 1818, BM 1824, ILST 6, SPS 115, and TGLA 126 had a minimal set of alleles. The maximum number of alleles, 15, was observed at the TGLA53 locus. Frequencies of frequently occurring alleles at loci with five alleles were 0.339 - 0.580, with the highest frequency observed in allele 248 at the SPS 115 locus. At the TGLA53 locus, allele 162 had the highest frequency of occurrence - 0.226. The average level of actual and expected heterozygosity was 0.757 and 0.738, respectively, and the fixation index was minus 0.031. Thus, the controlled herd of the Black-and-white breed had a slight excess of heterozygotes and a moderate degree of heterozygosity.
Origin of the ultrahigh field-induced strain in the Gd-doped 0.854Bi0.5Na0.5TiO3-0.12Bi0.5K0.5TiO3-0.026BaTiO3 ternary ceramic system

Abstract
This study focused on analyzing the ferroelectric, piezoelectric, and dielectric properties of lead-free Bi0.487Na0.427K0.06Ba0.026TiO3 (0.854BNT-0.12BKT-0.026BT) ternary ceramic system by systematically doping 0.001, 0.01, 0.1, 0.5, and 1.0 mol% Gd2O3. The specific composition that was investigated is located at the tetragonal side of the rhombohedral-tetragonal morphotropic phase boundary (MPB) region. Undoped and Gd-doped BNT-BKT-BT ceramics were produced by the conventional solid-state reaction method. Ferroelectric, piezoelectric, and dielectric properties of ceramics were analyzed by carrying out electrical measurements from sintered samples. An ultrahigh field-induced unipolar strain of 0.52% at 65 kV cm−1, with a converse piezoelectric coefficient d33* of up to 795 pm V−1, was achieved with 0.5 mol% Gd doping. This was attributed to the Gd dopant disrupting the normal ferroelectric order and leading to the formation of a nonpolar relaxor phase. The field-induced transition from the nonpolar relaxor phase to the normal ferroelectric phase resulted in relatively large field-induced strain values in the 0.5 mol% Gd-doped ceramics. These results suggest that Gd-doped BNT-BKT-BT ceramics hold promise for digital actuator applications.

Published: August 2024

Abstract
A self-doped conducting polyaniline was used as a hole transport layer (HTL) in organic photovoltaics (OPVs) [indium tin oxide/HTL/zinc-phthalocyanine/C70/bathocuproine/Al]. This polyaniline was characterized by phosphonic acid neutralized with pyridine (PMAP:Py). The current–voltage characteristics were evaluated and were comparable to those of the devices using a conventional hole transport material, poly(3,4-ethylenedioxythiophene) doped with poly(styrenesulfonate) (PEDOT:PSS). PMAP:Py-based OPVs stored in both nitrogen and ambient atmosphere had a longer lifetime than PEDOT:PSS-based ones.

Abstract
We performed electrical resistivity and X-ray diffraction measurements on the BiS2-based compound, EuSr2Bi2S2.5Se1.5F4, under high pressure using cubic and diamond anvil cells, respectively. We have also measured electrical resistivity at low temperatures and ambient pressures. The superconducting transition temperature (T
c) was 1.13 K at ambient pressure and EuSr2Bi2S2.5Se1.5F4 was found to behave like a superconductor. Upon the application of increased pressure, T
c increased and then decreased again, which was attributed to the structural phase transitions that accompany increased pressure in EuSr2Bi2S2.5Se1.5F4 superconductors.

Published: August 2024

Climate change is characterised by long-term changes in typical weather patterns, which can span from several decades to millions of years. Variations in temperature, precipitation, and other climatic factors are among the variables often used to quantify or qualify climate change. Most scholars recognize droughts and floods as two prominent consequences of climate change. Hence, the utilisation of climate change indicators such as periods of drought and heavy rainfall is of utmost importance. U. This study aimed at assessing patterns of dry and wet spell implications in the Central and Northern regions of eThekwini district municipality using historical climate data (1990–2022) on precipitation and temperatures (maximum and minimum) to determine the frequency, intensity, and duration of dry spells and wet spells. The findings revealed that the Central Region had almost double the rainfall compared to the Northern Region, which is particularly concerning since elevated levels of precipitation during a period of heightened moisture can result in the occurrence of floods, landslides, and an augmented supply of water. Frequent dry spells, indicative of severe drought, primarily affect the Northern region, posing a challenge to communities through water scarcity, agricultural losses, and hunger. Citizens of these areas are projected to be more vulnerable to extreme weather events; therefore, the need for a profound understanding of dry and wet spells and their socio-economic ramifications is evident. As communities worldwide grapple with the consequences of these climatic fluctuations, academic inquiry is essential to providing guidance for effective policy formulation, disaster management, and sustainable development.

Abstract

Objective:
Radiation therapy (RT) in the form of stereotactic radiosurgery (SRS) or whole-brain radiation therapy (WBRT) is fundamental for managing brain metastasis (BM). We analyzed national trends in RT and BM patient survival between 2010 and 2019.

Materials and Methods:
The US National Cancer Database was queried for patients receiving RT for BMs who were originally diagnosed with primary non-small cell lung cancer (NSCLC), small cell lung cancer, breast cancer, and melanomas from 2010 to 2019. Patients were grouped by WBRT (5-15 fractions; 20-45 Gy) or SRS (1-5 fractions; 10-40 Gy) treatment. Univariate and multivariate logistic regression analyses identified factors associated with receiving SRS over WBRT. Differences in treatment trends were assessed with Kruskal-Wallis tests. Post-treatment survival was assessed using Kaplan-Meier analysis and a Cox proportional hazards model.

Results:
In total, 59,839 patients were included; 41,197 (68.8%) received WBRT and 18,642 (31.2%) received SRS. Patients who were more recently diagnosed, treated at facilities outside of the East Central regions, insured, diagnosed with NSCLC subtype or melanoma, and who received chemo-/immunotherapy had higher odds of being treated with SRS (all P < .005). SRS, a more recent primary diagnosis, conjunctive use of chemo/immunotherapy, and luminal A/B breast cancer histologies (all P < .01) correlated with increased survival.

Conclusion:
The use of SRS has increased with patient survival over the last decade. We hypothesize that in addition to SRS-reducing neurotoxicity, this increase is due to guideline relaxation, improved techniques, and increased accessibility. Increased patient survival also indicates a possible relationship between SRS usage and improved survival.

Abstract
We present results from simultaneous far-ultraviolet (FUV) and near-ultraviolet (NUV) observations of T Tauri stars (TTSs) in the Taurus molecular cloud with UVIT/AstroSat. This is the very first UVIT study of TTSs. From the spectral energy distribution of TTSs from FUV to IR, we show that classical TTSs (CTTSs) emit significantly higher UV excess compared to weak-line TTSs (WTTSs). The equivalent blackbody temperatures corresponding to the UV excess in CTTSs (>104 K) are also found to be relatively higher than those in WTTSs (<9250 K). From the UV excess, we have reclassified two WTTSs (BS Tau and V836 Tau) as CTTSs, which has been supported by the follow-up optical spectroscopic study using the Himalayan Chandra Telescope, showing strong Hα line emission. We find that CTTSs show strong excess emission in both the FUV (>107) and NUV (>103) bands, while WTTSs show strong excess only in the FUV (≲105), suggesting that excess emission in the NUV can be used as a tool to classify the TTSs. We also find a linear correlation between UV luminosity (a primary indicator of mass accretion) and Hα luminosity (a secondary indicator of mass accretion) with a slope of 1.20 ± 0.22 and intercept of 2.16 ± 0.70.

Abstract
We present the timing analysis of 10 archived XMM-Newton observations with an exposure of >40 ks of Markarian 421. Mrk 421 is the brightest high-frequency-peaked BL Lac object emitting in X-rays produced by electrons accelerated in the innermost regions of a relativistic jet pointing toward us. For each observation, we construct averaged X-ray spectra in 0.5–10 keV band, as well as 100 s binned light curves (LCs) in various subbands. During these observations, the source exhibited various intensity states differing by close to an order of magnitude in flux, with the fractional variability amplitude increasing with energy through the X-ray band. Bayesian power spectral density analysis reveals that the X-ray variability can be characterized by a colored noise, with an index ranging from ∼ −1.9 to −3.0. Moreover, both the standard cross-correlation function and cross-spectral methods indicate that the amount of time lags increases with the energy difference between two compared LCs. A time-dependent two-zone jet model is developed to extract physical information from the X-ray emission of Mrk 421. In the model, we assume that the jet emission mostly comprises a quasi-stationary component and a highly variable one. Our results show that the two-zone model can simultaneously provide a satisfactory description for both the X-ray spectra and time lags observed in different epochs, with the model parameters constrained in a fully acceptable interval. We suggest that shocks within the jets may be the primary energy dissipation process responsible for triggering the rapid variability, although magnetic reconnection cannot be excluded.
