Breast cancer is the most prevalent neoplasia among women worldwide. For the estrogen receptor-positive (ER+) phenotype, tamoxifen is the standard hormonal therapy; however, it carries the risk of promoting endometrial carcinoma. Hence, we aimed to evaluate the antiproliferative effect of the phytochemical α-mangostin (AM) as a co-adjuvant alongside tamoxifen on breast cancer cells to improve its efficacy while reducing its adverse effects on endometrium. For this, ER+ breast cancer cells (MCF-7 and T-47D) and endometrial cells (N30) were treated with AM, 4-hydroxytamoxifen (4-OH-TMX), and their combination. Cell proliferation was evaluated using sulforhodamine B assay, and the pharmacological interaction was determined through the combination index and the dose reduction index calculation. The genes KCNH1, CCDN1, MKI67, and BIRC5 were amplified by real-time PCR as indicators of oncogenesis, cell cycle progression, cell proliferation, and apoptosis, respectively. Additionally, genes involved in ER signaling were analyzed. In breast cancer cells, the combination of AM with 4-OH-TMX showed a synergistic antiproliferative effect and favorable dose reduction. AM and 4-OH-TMX decreased KCNH1, CCND1, and BIRC5 gene expression. In endometrial cells, AM decreased MKI-67 gene expression, while it reverted the 4-OH-TMX-dependent CCND1 upregulation. This study establishes the benefits of incorporating AM as a co-adjuvant for first-line ER+ breast cancer therapy.

Published: November 2023

As an environmental parameter, the chlorophyll-a concentration (Chl-a) is essential for monitoring water quality and managing the marine ecosystem. However, current mainstream Chl-a inversion algorithms have limited accuracy and poor spatial and temporal generalization in Case II waters. In this study, we constructed a quantitative model for retrieving the spatial and temporal distribution of Chl-a in the Bohai–Yellow Sea area using Geostationary Ocean Color Imager (GOCI) spectral remote sensing reflectance (Rrsλ) products. Firstly, the GOCI Rrsλ correction model based on measured spectral data was proposed and evaluated. Then, the feature variables of the band combinations with the highest correlation with Chl-a were selected. Subsequently, Chl-a inversion models were developed using three empirical ocean color algorithms (OC4, OC5, and YOC) and four machine learning methods: BP neural network (BPNN), random forest (RF), AdaBoost, and support vector regression (SVR). The retrieval results showed that the machine learning methods were much more accurate than the empirical algorithms and that the RF model retrieved Chl-a with the best performance and the highest prediction accuracy, with a determination coefficient R2 of 0.916, a root mean square error (RMSE) of 0.212 mg·m−3, and a mean absolute percentage error (MAPE) of 14.27%. Finally, the Chl-a distribution in the Bohai–Yellow Sea using the selected RF model was derived and analyzed. Spatially, Chl-a was high in the Bohai Sea, including in Laizhou Bay, Bohai Bay, and Liaodong Bay, with a value higher than 4 mg·m−3. Chl-a in the Bohai Strait and northern Yellow Sea was relatively low, with a value of less than 3 mg·m−3. Temporally, the inversion results showed that Chl-a was considerably higher in winter and spring compared to autumn and summer. Diurnal variation retrieval effectively demonstrated GOCI’s potential as a capable tool for monitoring intraday changes in chlorophyll-a concentrations.

Published: November 2023

<p>In time-of-flight positron emission tomography (TOF-PET), the timing capabilities of the scintillation-based detector play an important role. An approach for fast timing is using the so-called metascintillators, which combine two materials leading to the synergistic blending of their favourable characteristics. An added effect for BGO-based metascintillators is taking advantage of better transportation of Cherenkov photons through UV-transparent materials such as plastic (type EJ232). To prove this, we use an optimized Coincidence Time Resolution (CTR) setup based on electronic boards with two output signals (timing and energy) and near-ultraviolet (NUV) and vacuum-ultraviolet (VUV) silicon photomultipliers (SiPMs) from Fondazione Bruno Kessler (FBK), along with different coupling materials. As a reference detector, we employed a 3×3×5 mm3 LYSO:Ce,Ca crystal pixel coupled with optical grease to a NUVHD SiPM. The evaluation is based on low threshold rise-time, energy and time of arrival of event datasets. Timing results of a BGO and EJ232 metapixel show Detector Time Resolutions (DTRs) of 159 ps for the full photopeak. We demonstrate the possibility of event discrimination using subsets with different DTR from the rising time distributions (RTD). Finally, we present the synergistic capability of metascintillators to enhance Cherenkov photons detection when used along with VUV-sensitive SiPMs. </p>

The Contributions of Case Study Mixed Methods Research in Understanding Faculty Experiences in the New Virtual Working Environment Caused by COVID- 19 at a University: An Illustrative Example
Authors: Kamalodeen Vimala Judy , Cook Loraine D. 
Published: November 2023

This paper presents a discussion and reflections on using a mixed-method case study research design to explore the remote work experiences during the COVID-19 pandemic. As a team, we used our own experiences and in-depth interviews with six teacher educators in the case context of a university. The themes of the analysis of these interviews were used to build a survey instrument to see to what extent other teacher educators within the boundary of the case had similar or different experiences during the first academic year of COVID-19 (2020/21). Through the discussions and reflections on the purpose of the study, the research experience and the role of case study mixed methods research, the article offers an illustration of conducting mixed-method case study research embedded with an exploratory sequential mixed-methods design. These reflections can be helpful to novice researchers about to embark on a combined case study mixed methods design and provide insights and useful details for the more advanced researcher.
Transformation of the model of local self-government during the crisis and subsequent dismantling of the Soviet political system at the end of the 20th century in Ryazan Region
Authors: Антонов А.С. 
Published: November 2023

Статья посвящена актуальной на сегодняшний день проблеме формирования новой российской государственности в конце XX века. Этот процесс отличается серьезными потрясениями и уникальным опытом коренного преобразования всей политической системы без тектонических разломов войн и революций, в связи с чем вопрос становления и развития новой системы самоуправления в регионах является одним из самых актуальных. В статье рассматривается трансформация модели местного самоуправления в условиях кризиса и демонтажа советской политической системы в конце ХХ века. Особое внимание уделяется начавшейся в середине 80-х годов ХХ века перестройке, когда внимание сосредотачивалось не на решении нараставших в стране экономических проблем, а на реорганизации политической системы страны — Союза Советских Социалистических Республик. Прослеживаются этапы выполнения одной из важнейших задач реформирования советского общества и государства, в частности эволюция роли Советов в советском государстве. Целью статьи является комплексное исследование процесса создания, становления и развития органов местного самоуправления в Рязанской области в период демонтажа советской политической системы. Анализируются новые, впервые вводимые в научный оборот архивных документы Государственного архива Рязанской области — протоколы заседаний Городского совета народных депутатов за период с 1990 года по 1992 год.
The article is devoted to the important issue of formation of the new Russian state at the end of the 20th century. This process is distinguished by serious upheavals and a unique experience of a radical transformation of the entire political system. This happened without destructive wars or revolutions. Due to this circumstance the issue of the formation and development of a new system of self-government in the regions is a major theme to address. The article deals with the transformation of the model of local self-government in the conditions of the crisis and subsequent collapse of the Soviet political system at the end of the 20th century. Particular attention is paid to the perestroikathat began in the mid-1980s, when attention was focused not on solving the economic problems that were growing in the country, but on reorganizing the political system of the country, the Union of Soviet Socialist Republics. The research focusses on the stages of reforming the Soviet society and the state, in particular, on the evolution of the role of the Soviets (Councils) in the Soviet state. The article presents a comprehensive study of the process of creation, formation and development of local governments in the Ryazan Region during the dismantling of the Soviet political system. It quotes new archival documents of the State Archives of the Ryazan Region, namely the minutes of meetings of the City Council of People’s Deputies for the period from 1990 to 1992, analyzed here for the first time.
Interpretations of images of classical Chinese poetry in Russian translations (poems about separation)
Authors: Аннушкин В.И. , Хаофан Л. 
Published: November 2023

Данная статья посвящена описанию и анализу интерпретации образов китайской классической поэзии о разлуке в переводах на русский язык. Исследование имеет актуальность в контексте культурного обмена между Китаем и Россией, а также в области перевода и литературоведения. Китайская поэзия о разлуке обладает глубокой символикой, которая олицетворяет эмоциональные состояния и жизненные переживания. Однако перевод этих образов на русский язык представляет сложность из-за культурных различий и особенностей языковых систем. В этом контексте исследование направлено на выявление особенностей трансляции таких образов, как 柳 (ива), 春草 (весенняя трава), 月亮 (луна), и их смысловой окраски из оригинальных китайских стихотворений в русскоязычные переводы. Результаты исследования позволяют лучше понять классическую китайскую поэзию о разлуке и оценить ее значение для русскоязычной аудитории, а также способствуют совершенствованию переводческой практики. Переводчики обращают особое внимание на передачу образности и эмоциональной окраски стихов, но при этом возможны потери некоторых нюансов и тонкостей оригинального текста. Полученные результаты имеют практическую значимость в области перевода и могут быть применены в образовательных целях, а также служить основой для дальнейших исследований в области сравнительной литературы и культурологии, благоприятствуя глубокому пониманию и взаимодействию между китайской и русской литературными традициями.
This article is devoted to description and analysis of Russian translators’ interpretation of images of classical Chinese poetry about separation. The study is relevant in the context of cultural exchange between China and Russia, as well as for study of translation and literary criticism. Chinese poetry about separation contains deep symbolism that personifies emotional states and life experiences. However, translating such images into Russian is difficult due to cultural differences and peculiarities of language systems. In this context, the study is aimed at identifying the specifics of rendering such images as 柳 (a willow), 春草 (spring grass), 月亮 (the moon), and their semantic coloring from original Chinese poems into Russian. The results of the study help us to better understand classical Chinese poetry about separation and evaluate its significance for the Russian-speaking audience; they also enrich the traditions of poetic translation practice. Translators pay special attention to the transfer of imagery and emotional coloring of poems, but certainly some nuances and subtleties of the original text may be lost in translation. The results obtained are of practical importance in the field of translation and can be used for educational purposes, as well as serve as a basis for further research in the field of comparative literary and cultural studies, resulting in deeper understanding and interaction between Chinese and Russian literary traditions.
Abundances of Iron-peak Elements in the B8 Mn Star HD 110073
Authors: Monier Richard 
Published: November 2023

Abstract
The synthesis of spectral intervals in the optical range allows the determination of LTE abundances of several iron-peak elements for the chemically peculiar B8 Mn star HD 110073. Titanium, chromium and manganese are found to be overabundant by factors of 19, 4 and 250 times their respective solar abundances. Iron and nickel are deficient by factors of 0.25 and 0.10. Weak lines of Cr ii formed deep in the atmosphere yield lower chromium abundances than strong lines do by a factor of 2. This supports that chromium is probably stratified vertically in the atmosphere of HD 110073. Several weak flat-bottomed lines which could be caused by vertical stratification of the abundances are present throughout the spectra. The new abundance determinations differ from previous determinations partly because the atomic data have changed. A non-uniform distribution of the elements over the surface of HD 110073 could also account for variation of the lines with time.
No Dispersed Single Radio Pulses Detected in Archival Parkes Pulsar Observations Targeting Supernova Remnants and Anomalous X-Ray Pulsars
Authors: Crawford Fronefield 
Published: November 2023

Abstract
Four supernova remnants and four anomalous X-ray pulsars were previously observed with the Parkes telescope in a campaign to detect pulsed radio emission from associated neutron stars. No signals were detected in the original searches of these data. I have reprocessed the data with the more recently developed HEIMDALL and FETCH software packages, which are optimized for single-pulse detection and classification. In this new analysis, no astrophysical pulses were detected having a signal-to-noise ratio above 7 from any of the targets at dispersion measures ranging from 0 to 104 pc cm−3. I include calculated fluence limits on single radio pulses from these targets.
La parodie, un genre intermédial récupéré par les fans : aimer, rire, satiriser, vivre
Authors: Vovou Ioanna 
Published: November 2023

Cet article prend pour objet les parodies des programmes audiovisuels sur des plateformes comme YouTube ou via l’application TikTok par des créateurs de contenu grecs, dans le contexte du développement d’une culture des fans qui agit sur le document télévisuel en le travestissant et en produisant des variations multiples. Au milieu d’un double processus de globalisation de la culture des fans et de publicisation des spécificités culturelles locales, les productions parodiques sont analysées sous le prisme d’une certaine conception postmédiatique des contenus audiovisuels. La participation intermédiale des publics dans la consommation des produits de la culture populaire apporte un élément crucial de déstabilisation de l’axe conceptuel (voire, parfois, idéologique) dichotomique « anciens/nouveaux médias ». Dans cet article, nous examinons la façon dont le travestissement parodique, ayant une longue tradition théâtrale et littéraire – télévisuelle aussi – est récupéré par les créateurs de contenu sur les plateformes, afin de questionner certaines continuités mais aussi des diversifications dans l’évolution intermédiale d’un genre qui laisse des traces dans ce que nous entendons par « mémoire médiatique ».

Authors: Kundu Gairik , Khamar Pooja , Modak Durgalaxmi , Mukherji Ritica , Bhatkal Anushree , Sinha Roy Abhijit , Shetty Rohit 
Published: November 2023

Purpose:
To assess 10-year visual and tomographic outcomes of topography-guided custom ablation (T-CAT) with corneal cross-linking (CXL) in eyes with keratoconus.

Methods:

T-CAT with CXL was performed in 600 eyes (522 patients). Based on the T-CAT ablation plan, the theoretical maximum ablation depth was 50 µm after epithelium removal. After ablation, accelerated corneal cross-linking (CXL) was performed in the central 8-mm zone (9 mW/cm
2
for 10 minutes in “epi-off” mode). The visual acuity and tomography were assessed.

Results:

There was significant improvement in uncorrected (
P
= .001) and corrected (
P
= .001) distance visual acuity after the procedure. Keratometry, root mean square lower order aberrations and higher order aberrations, defocus, coma 90°, and spherical aberration reduced significantly after surgery at 10 years of follow-up (
P
< .005). All Pentacam (Oculus Optikgerate GmbH) tomographic variables showed significant changes indicating regularization after T-CAT (
P
< .005). Flattening of greater than 5.00 diopters in maximum keratometry was noted in 6 eyes (1%). Two of 600 eyes progressed postoperatively and required repeat CXL.

Conclusions:
T-CAT plus CXL is a safe and effective technique even in the long term for regularizing the anterior corneal surface with significant visual improvement and reduction in higher order corneal aberrations.
