Published: December 2024

Abstract

Energy conservation, emission reduction, and voyage time optimization are critical concerns in the marine sector, where enhancing ship energy efficiency and sailing duration is essential for significant decreases in energy consumption and CO2 emissions. Existing studies generally focus on either sailing speed or route optimization, sometimes overlooking their interplay under continuously variable weather conditions, hence reducing the precision and quality of proposed solutions. This research presents an advanced Time Boundary Semicircles (TBS) Algorithm, which provides a robust and precise optimization model that incorporates involuntary speed reduction based on real-time weather data from the Copernicus Marine Environment Monitoring Service (CMEMS), subject to deterministic time boundaries. The TBS algorithm employs mathematical modeling to compute speed reductions dynamically and integrates Python libraries such as NumPy, Pandas, Matplotlib, and Cartopy to enhance waypoint optimization and software interactivity. This research compares the TBS algorithm to the SIMROUTE software, demonstrating its superior effectiveness in heavy weather scenarios with sailing time reductions ranging from 7–27.25%. Case studies validate the algorithm's efficacy through comprehensive simulation outputs, including map plots and detailed reports. They also highlight its potential for broader applications in aviation and land transport for route optimization. By bridging the gaps in maritime routing optimization, the TBS algorithm represents a significant advancement in sustainable and efficient transportation.

«СКАЗ О ТОМ, КАК ЛЕНИН ВЫЛЕЧИЛ БАБКУ АГРАФЕНУ»ИСТОРИКО-ЛИТЕРАТУРНАЯ МИСТИФИКАЦИЯ И ЕЕ СМЫСЛЫ

Published: December 2024

В публикации актуализируется обозначившаяся в 1920е гг. проблема поиска путей и форм диалога между большевистской властью и деревней. Перевод на понятный крестьянину язык идеологических установок нового политического режима потребовал наладить разговор с деревней, что привело к увеличению числа самоописательных нарративов сельчан. Наряду с этим, однако, стали появляться и псевдофольклорные произведения, созданные профессиональными литераторами. Как показано на примере одного из них, Сказа о том, как Ленин вылечил бабку Аграфену, функционал таких историколитературных мистификаций состоял, помимо прочего, в формировании посмертного мифологизированного образа В.И. Ленина. Анализ ретроспективного источника показывает, что к середине 1920х г. этот образ в целом уже был очерчен, но при этом недостаточно убедителен в своих деталях. Будучи феноменом переходного периода, Сказ запечатлел невозможную позже травестию сакрального и профанного, а также недоформулированность актуальных и перспективных агитационных установок. Кроме того, ретроспективный источник интересен и важен как олицетворение предчувствия близкой тотальной советизации крестьянского мира, идеи которой уже просочились в публичное пространство. Ключевые слова: эгоисточники, крестьянский мир, народная письменность, историколитературная мистификация, псевдофольклор, модернистская эстетика, культ Ленина, религиозный дискурс
The publication actualizes the problem of finding ways and forms of dialogue between the Bolshevik government and the countryside that revealed itself in the 1920s. The translation of the new political regimes ideological guidelines into a language understandable to the peasant demanded that a conversation with the countryside be established, which led to an increase in the number of selfdescriptive narratives of the villagers. Along with this, however, pseudofolklore works created by professional writers began to appear. The example of one of them, A Tale about how Lenin cured old woman Agrafena, demonstrates that the functionality of such historical and literary hoaxes consisted, among other things, in taking shape of V.I. Lenins posthumous mythologized image. Analysis of the retrospective source shows that by the mid1920s, this image in general has already been outlined, but it was not convincing in its details. Being a transitional phenomenon, A Tale ... captures travesty of the sacred and the profane that would be impossible later, it also indicates the lack of formulation of current and future propaganda guidelines. In addition, this retrospective source is interesting and important as it embodies a premonition of the impending total Sovietization of the peasant world, which ideas have already been leaked into public space.

The Effects of Agency Problems and Dividend Policy on the Asymmetric Behaviour of Selling, General and Administrative Expenses: Does Ownership Structure Matter?
Authors: Okechukwu Enyeribe Njoku  , Younghwan Lee  , Jeong-Ho Koo  
Published: December 2024

This article investigates the effects of agency problems and dividend policy on the asymmetric behaviour of Selling, General, and Administrative (SG&A) expenses, with an emphasis on Korean business ownership structures. Employing a robust dataset of 4,279 observations from the Korean Composite Stock Price Index from 2011 to 2021, our empirical investigation combined multiple regression models such as OLS, fixed effects, random effects and the Generalised Method of Moments (GMM) to contain endogeneity problems. The research objectives include the examination of the relationship between SG&A cost asymmetry and agency problems, the impact of dividend policy on SG&A costs, and the intervening function of Korean business ownership structures, particularly Chaebols. Unexpectedly, the results reveal that higher free cash flow is linked to lower SG&A cost asymmetry, suggesting that agency concerns can be mitigated in such corporations. Improved asset utilisation increases cost asymmetry, whereas larger operating expenses reduce asymmetry. Furthermore, higher cash dividends and payout ratios are associated with reduced SG&A cost asymmetry, which contradicts the premise that dividend constraints correlate with a higher degree of cost asymmetry. According to ownership structure analysis, Chaebols' concentrated ownership results in stronger control over cash flow, eliminating cost asymmetry more efficiently than in non-Chaebol firms. These findings add to the literature on agency theory, cost behaviour, and corporate governance, providing managers and shareholders with beneficial insights. To promote business sustainability, improved handling of agency concerns and cost efficiency, this study recommends tailored corporate governance policies that takes ownership structures into account.
Deep Learning-based U-Mamba Model to Predict Differentiated Gastric Cancer using Radiomics Features from Spleen Segmentation
Authors: Shang Hui , Tong Ying , Li Mingyu , Xu Shuangyan , Xu Lihang , Cao Zhendong 
Published: December 2024

Objective:
This study aimed to develop an automated method for segmenting spleen computed tomography (CT) images using a deep learning model to
address the limitations of manual segmentation, which is known to be susceptible to inter-observer variability. Subsequently, a prediction model
for gastric cancer (GC) differentiation was constructed alongside radiomics, and a nomogram was generated to investigate its clinical guiding
significance.

Methods:
This study enrolled 262 patients with pathologically confirmed GC. We employed a deep learning model, U-Mamba, to achieve fully automated
segmentation of the spleen CT images. Subsequently, radiomic features were extracted from the entire spleen CT images, and significant features
were identified through dimensionality reduction. The clinical and radiomic features were permuted and combined to create three predictive
models: the CL model, the RA model, and the CR model. Finally, the model with superior performance was represented as a nomogram.

Results:
A total of 30 radiomic features and 1 clinical feature were considered valuable through dimensionality reduction and selection. The RA model
demonstrated greater discriminative power than both the CR model and the CL model. A nomogram based on the logistic clinical model was
created to facilitate the application and validation of the clinical model.

Conclusion:
The radiomic features obtained through the automated segmentation of the spleen using deep learning demonstrate efficacy in predicting the degree
of differentiation in GC. These features offer valuable guidance for clinical decision-making in the form of a nomogram.
Effect of Accelerated Aging on the Microtensile Bond Strength of a Two-Step Adhesive Containing a Universal Adhesive Primer, an in vitro study
Authors: Daneshpooy Mehdi , Bahari Mahmoud , Dabaghi Tabriz Fatemeh , Alizadeh-Oskoee Parnian , Fahim Zhila 
Published: December 2024

Background
Despite the advantages of one-step universal adhesives, concerns about their bond durability exist. By introducing a two-step adhesive using universal bonding technology, the study aimed to evaluate the effect of accelerated aging on the microtensile bond strength (µTBS) of this adhesive when applied to dentin.

Materials and Methods
In this in vitro study, 16 extracted sound human third molar teeth were selected. Specimens were prepared by cutting the occlusal enamel perpendicular to the longitudinal axis and categorized into four groups of 18 each: G2-Bond Universal (GC Corp, Tokyo, Japan) in etch-and-rinse mode (GU-ER), G2-Bond Universal in self-etch mode (GU-SE), G-Premio Bond in etch-and-rinse mode (GP-ER), and G-Premio Bond (GC Corp, Tokyo, Japan) in self-etch mode (GP-SE). The resin composite was bonded to the dental surfaces based on the manufacturer’s instructions and light-cured for 10 seconds using an LED curing unit (Demetron A2, Kerr, Scafati, Italy, 1200 mW/cm2). The bonded specimens were then sectioned into 1 mm2 sticks and divided into two subgroups (n=36). One subgroup (9 specimens from each adhesive) underwent thermal cycling, while the other was immersed in 10% sodium hypochlorite for three hours to simulate accelerated aging. The µTBS was measured, and failure modes were determined. Data were analysed using two-way ANOVA, the Sidak test, and the Independent Samples T-Test

Results
The highest mean μTBS was associated with GU-SE (29.63 ± 8.59 MPa), while the lowest was observed with GP-ER (18.65 ± 9.33 MPa). The µTBS values decreased following aging (p < 0.001). The values for GU-SE and GU-ER were significantly higher than those for GP-ER (p < 0.001 and p = 0.005, respectively). GU-SE and GU-ER showed a slight, statistically insignificant decrease in bond strength with aging (p = 0.133 and p = 0.060, respectively). However, GP-SE and GP-ER showed significant reductions in bond strength after aging (p = 0.004 and p = 0.001, respectively). The interaction between accelerated aging and study groups was not significant (p = 0.311), indicating a uniform effect of aging in all groups. Failure modes were similar in groups (p > 0.05), with adhesive failure being the most common type. G-Premio had more adhesive failures than G2-Bond, though this difference was not statistically significant.

Conclusion
Two-step universal adhesive performed better than one-step system during aging. In etch-and-rinse mode, the two-step adhesive significantly improved bond strength, while in self-etch, both adhesives showed similar performance.
Effects of Normal Cognitive Aging on Spoken Word Frequency: Older Adults Exhibit Higher Function Word Frequency and Lower Content Word Frequency than Young Adults
Authors: Burke Erin , Patrick Karlee , Hamrick Phillip , Gunstad John 
Published: December 2024

Background
Recent work indicates that word frequency (WF), broadly defined as an estimate of how often a given word is produced during spontaneous speech, has been shown to be a sensitive marker for conditions like mild cognitive impairment (MCI) and Alzheimer’s disease (AD). WF has been linked to cognitive declines observed in these groups. However, it is largely unknown how WF for distinct word classes change as part of normative cognitive aging, and to what extent factors like education and life experience may protect against age-related cognitive decline.

Objective
The current study examined WF and its association with cognitive test performance in older and younger adults. Higher WF values indicate the use of more common, higher frequently used words that are more readily retrieved from the lexicon, whereas lower WF values indicate the use of less common, lower frequency words.

Methods
Expository speech transcripts of 70 older and 130 younger adults were analyzed. Subject-level WF indices were computed for all words (AWs), content words (CWs) and function words (FWs). Between-group differences in WF and neuropsychological test performance were examined using independent samples t-tests and associations between WF and cognitive performance were evaluated with Pearson correlations. Follow-up analyses clarified the possible contribution of education.

Results
Higher average AW and CW frequency was observed in younger adults and higher AW frequency was associated with poorer performance on a test of mental reasoning (Cognitive Estimation Test). Though small, differences between age groups remained significant after accounting for education levels.

Conclusion
The current results show generally preserved WF in older adults and suggest that healthy cognitive aging and formal education do not drive the age-related changes in WF found in other studies. If replicated, such findings suggest that a shift from lower to higher frequency words in the spontaneous speech of older adults may be a marker of early neuropathological changes rather than normative cognitive aging and that the specific pattern may be influenced by sociocultural factors like language exposure and life experience. Future studies examining changes in lexical retrieval with advancing age will help clarify the impact of normative cognitive aging on WF indices and the extent to which analysis of spontaneous speech may help with early detection for conditions like MCI and AD.
Investigating the Apoptosis Status of Peripheral Lymphocytes in COVID-19 Patients in the Post-COVID-19 Era: A Cross-Sectional Study
Authors: Abiri Elaheh , Raesi Rasoul , Kashani Maryam Haji Qasem 
Published: December 2024

Background
Although COVID-19 has been contained and the world is now in the post-corona era, evidence shows that the coronavirus can still cause hospitalization and even death of patients by inducing cell apoptosis.

Aim
The present study was conducted to investigate the apoptosis status of peripheral lymphocytes in patients with COVID-19 in the post-corona era.

Methods
This cross-sectional study was conducted using a simple random sampling method in December, 2023, by examining the apoptosis level of peripheral lymphocytes in samples taken from 54 COVID-19 patients hospitalized in Velayat Damghan Hospital. Using an RT-PCR test, the nucleic acid of the SARS-CoV-2 virus was identified in all COVID-19 patients. Apoptosis assay was performed using the Annexin V/Propidium Iodide technique. Statistical analysis was performed using GraphPad Prism and inferential statistics tests.

Results
A total of 54 patients with COVID-19 in the age range of 21 to 59 years, of whom 44.4% were hospitalized in the non-ICU department and 55.5% in the ICU department. Among them, 27.7% required intubation, while 27.7% did not need intubation. The highest level of apoptosis in peripheral lymphocytes was observed in the intubated ICU (4.28%) and non-intubated ICU (1.89%) groups. The intubation group showed a significant difference from the non-intubation group (p < 0.01). In all groups, there was a significant increase in the level of apoptosis compared to the healthy control group (p < 0.01).

Conclusion
The increased apoptosis in COVID-19 patients raises concerns about the potential impact on immune function and the development of long-term health complications.
