Authors: Xiao Jin , Zhang Yingfeng , Li Bowen , Zhang Shuwen , Gao Ya , Wang Han , Zhang John Z.H. , Zhu Tong
Published: February 2025

Accurate prediction of reaction energetics remains a fundamental challenge in computational chemistry, as conventional density functional theory (DFT) often fails to reconcile high accuracy with computational effi ciency. Here, we introduce Deep post-Hartree-Fock (DeePHF), a machine learning framework that synergistically integrates neural networks with quantum mechanical descriptors to achieve CCSD(T)-level precision while retaining the efficiency of DFT. By establishing a direct mapping between the eigenvalues of local density matrices and high-level correlation energies, DeePHF circumvents the traditional accuracy-scalability trade-off . Trained on a limited dataset of small-molecule reactions, our method demonstrates unprecedented performance across multiple benchmark datasets, exhibiting exceptional transferability. In fact, its accuracy even surpasses that of advanced double-hybrid functionals, all while maintaining O(N^3) scaling. DeePHF offers a promising pathway to bridge the gap between high-level quantum chemistry methods and the practical demands for scalable, accurate models in computational chemistry, and with further refinement, it is poised to make significant contributions to the advancement of chemical reaction modeling.
Optimizing Portfolio Performance through Clustering and Sharpe Ratio-Based Optimization: A Comparative Backtesting Approach
Authors: Park Keon Vin
Published: February 2025

Optimizing portfolio performance is a fundamental challenge in financial modeling, requiring the integration of advanced clustering techniques and data-driven optimization strategies. This paper introduces a comparative backtesting approach that combines clustering-based portfolio segmentation and Sharpe ratiobased optimization to enhance investment decision-making.
First, we segment a diverse set of financial assets into clusters based on their historical log-returns using K-Means clustering. This segmentation enables the grouping of assets with similar return characteristics, facilitating targeted portfolio construction.
Next, for each cluster, we apply a Sharpe ratio-based optimization model to derive optimal weights that maximize risk-adjusted returns. Unlike traditional mean-variance optimization, this approach directly incorporates the trade-off between returns and volatility, resulting in a more balanced allocation of resources within each cluster.
The proposed framework is evaluated through a backtesting study using historical data spanning multiple asset classes. Optimized portfolios for each cluster are constructed and their cumulative returns are compared over time against a traditional equal-weighted benchmark portfolio.
Our results demonstrate the effectiveness of combining clustering and Sharpe ratio-based optimization in identifying high-performing asset groups and allocating resources accordingly. The selected cluster portfolio achieved a total return of 140.98%, with an annualized return of 24.67%, significantly outperforming the benchmark portfolio, which achieved a total return of 107.59% and an annualized return of 20.09%. The Sharpe ratio of the selected portfolio (0.84) further highlights its superior risk-adjusted performance compared to the benchmark portfolio (0.73).
This methodology provides a systematic and data-driven approach to portfolio optimization, achieving superior returns while maintaining a reasonable level of risk.
Study On Structure Monitoring Using Laser Scanner Technology
Authors: Erdenenemekh Ganzorig
Published: February 2025

Ground Laser Scanning (TLS) is a reliable tool for high-precision structural deformation monitoring. Reinforced concrete and masonry structures require deformation monitoring to meet high safety requirements. As a result, it is important to monitor deformation and assess the safety of these structures against damage. It is desirable to predict the load displacement of the structure in terms of elastic and inelastic responses. For structures, measurements based on ground laser scanning technology are performed. This research work presents a comparison of the initial and optimized point cloud. The surface uncertainty of various orders is investigated by covering the surface approximation measurement area. Based on ground laser scanning measurements, the results of the structure surface are correlated with the test results and are monitored by subtracting them from the deformation calculation.
Green Innovations’ Differential Roles in Shaping Firm Productivity under Environmental Law via Optimized PSM-DID
Authors: Jiang Yi
Published: February 2025

This study utilizes both cross-sectional and year-by-year settings of Propensity Score Matching with Difference-in-Differences (PSM-DID) method to analyze the impact of the 2015 Environmental Protection Law (NEPL) on green innovations and total factor productivity in heavy polluting firms within manufacturing industries, spanning 2010–2018. Employing the Cobb-Douglas production function framework, it posits green innovation as a crucial technological resource augmenting tangible assets and technological productivity. The analysis reveals differentiated effects of NEPL on various types of green innovations: a negative impact on alternative energy and green transportation patents, while energy-saving and waste management patents remain largely unaffected. This suggests a crowding-out effect of environmental regulations on certain green innovations. Interestingly, heterogeneity analysis shows that smaller, less profitable heavy-polluting firms economically gain more from green innovations, particularly in waste management and energy-saving, while strict policies pose challenges for the alternative energy sector, highlighting the need for diverse, more supportive and adaptive policy approaches.

Представления английских дипломатово министрах Екатерины II
Authors: Лабутина Т.Л.
Published: February 2025

В статье рассматриваются сведения английских послов при дворе Екатерины II о первых министрах императрицы — канцлере А.П. Бестужев-Рюмине, Н.И. Панине, Г.А. Потемкине. Их характеристики не всегда были объективными и непредвзятыми. Чаще всего на них влияли неудачи британской стороны в дипломатическом поединке с императрицей и русскими сановниками. В то же время в информации дипломатов содержится много новых и интересных фактов о жизни и деятельности первых лиц российского государства последней трети XVIII века, которые значительно расширяют наши представления о екатерининской эпохе.

The article deals with the testimonies of the British ambassadors at the court of Catherine II about the first Ministers of the Empress — Chancellor A.P. Bestuzhev-Ryumin, N.I. Panin, G.A. Potemkin. Their characteristics were not always objective and biased. Most often this was influenced by the failures of the British side in a diplomatic duel with the Empress and Russian dignitaries. At the same time, the information of diplomats contains many new and interesting facts about the life and activities of the first persons of the Russian state of the last third of the XVIII century, which significantly expands the views of our contemporaries about the Catherine era.
Brexit: обсуждение ситуации в Конгрессе США
Authors: Айриян Р.С.
Published: February 2025

Представленная статья посвящена анализу обсуждения в стенах Конгресса США вопроса о выходе Соединенного Королевства из состава Европейского союза. Автор, используя в первую очередь стенограммы Конгресса США и материалы комитетских слушаний, выделяет три основные проблемы, которые вызывали обеспокоенность у американских законодателей в связи с Брекзитом: развитие англо-американских торговых отношений, угроза срыва Белфастского соглашения, а также проблема вмешательства России в проведение референдума в Великобритании. Делается вывод, что отношение к двум вопросам в значительной степени было связано с партийной принадлежностью законодателей, но при этом своеобразным исключением становится обсуждение проблемы сохранения Соглашения Страстной пятницы.

The article is devoted to the analysis of the discussion in the US Congress on the exit of the United Kingdom from the European Union. The author, using primarily transcripts of the US Congress and materials from committee hearings, identifies three main problems that US legislators were concerned about Brexit: the development of Anglo-American trade relations, the threat of disruption of the Belfast Agreement, and the problem of Russia's interference in the referendum In Great Britain. It is concluded that the attitude to the two issues was largely related to the party affiliation of the legislators, but the discussion of the problem of maintaining the Good Friday Agreement becomes a peculiar exception.

Authors: Прокопов А.Ю.
Published: February 2025

В статье «Тайные средства борьбы: почтовый контроль на службе у британских спецслужб Великобритании» А. Прокопов исследует деятельность почтового контроля (или цензуру почтовой переписки), которая была организована в Великобритании вскоре после начала Первой мировой войны. Этот департамент осуществлял проверку всей почтовой корреспонденции, поступавшей из-за границы и отправлявшейся из Великобритании. В числе основных целей почтового контроля было не только противодействие вражеским спецслужбам, но и сбор, систематизация и распределение среди различных ведомств британского правительства наиболее полезной информации экономического, политического, военного характера. Умелое использование руководством Великобритании этих данных помогло в условиях войны ослабить сопротивление Германии и ее сателлитов.

The Postal control on the service of the British intelligence during the First World War In the article “Secret resources of struggle: the Postal control on the service of secret intelligence of Great Britain” A. Prokopov examines the activity of Postal control (or the censorship of postal correspondence) which was organized in Britain soon after the beginning of the First World War. This department accomplished examination of all postal items of mail which were sent from Britain and to it at that time. Among the main aims of the Postal control were not only to counteract the enemy intelligence services, but also to collect, systematize and distribute among different departments of British government the most useful information of economic, political, military character. The competent usage of this data by the British leaders helped them to weaken the resistance of Germany and its satellites during the war time.
Гарольд II Годвинсон и Уэльс: легитимация властив Англии накануне нормандского завоевания
Authors: Глебов А.Г.
Published: February 2025

Статья посвящена исследованию проблемы легитимации политической власти в Англии накануне Нормандского завоевания. Используя данные разнообразных источников, прежде всего, англосаксонских и англо-нормандских хроник, автор обосновывает предположение о том, что отказ короля Эдуарда Исповедника от передачи трона герцогу Нормандии Вильгельму и назначение наследником эрла Уэссекса Гарольда Годвинсона было, в том числе, связано с его авторитетом, как удачливого полководца. Особое внимание обращено на военные кампании последнего в Уэльсе, в частности, его взаимоотношения с валлийским королём Грифидом ап Лливелином, победа над которым, в конечном счете, сыграла решающую роль в восхождении Гарольда к высотам политической власти и последующем воцарении.

The paper is dedicated to the investigation of the political power legitimacy in England on the eve of the Norman conquest. Using different types of primary sources, mainly Anglo-Saxon and Anglo-Norman chronicles, the author grounds the assumption that king Edward the Confessor rejection to transfer the crown to William duke of Normandy and heir appointment of Harold Godwinson earl of Wessex was connected, among other reasons, with his prestige as a war leader. Special attention is paid to latter war companies in Wales, particularly to his conflicts with the Welsh king Gruffydd ap Llywelyn, victory over whom, as a matter of fact, played the key role in Harold’s ascension to the heights of political power and eventually to the English throne.
Creation of an adsorbent from spent diatomaceous earth tailored to purify water from oil
Authors: Rudenko E. Yu.
Published: February 2025

It is known that spent diatomaceous earth (diatomite; kieselguhr), one of the main waste products from the beer filtration process, can be used as an adsorbent to purify water from crude oil. The thermal and chemical modification of this waste product increases its oil capacity. The conducted study was aimed at obtaining a sorbent tailored to purify water from oil using different modifications of spent diatomaceous earth. Preliminary studies revealed that the modification of spent diatomaceous earth is affected by the chemical nature and concentration of the modifying agent, as well as the temperature and duration of exposure. Alkaline modification of spent diatomaceous earth is more effective than acid modification; modification with sodium hydroxide solution produces the greatest effect on oil capacity. The maximum oil capacity is exhibited by spent diatomaceous earth modified with 1.5 M sodium hydroxide solution at 75 °С for 120 min. In order to optimize the procedure for obtaining an adsorbent suitable for purifying water from oil, a full factorial design was implemented on the basis of preliminary experimental data using Statistica 10.0, and additional experiments were conducted. An analysis of Pareto charts of standardized effects revealed that the modification process of spent diatomaceous earth is significantly affected by the modifying reagent concentration and the modification process temperature. Therefore, modification with 1.5 M sodium hydroxide solution at 75 °С for 30 min is the most optimal and effective procedure for obtaining an adsorbent suitable for purifying water from oil.
Bootstrapping frustrated magnets: the fate of the chiral ${\rm O}(N)\times {\rm O}(2)$ universality class
Authors: Reehorst Marten , Rychkov Slava , Sirois Benoit , van Rees Balt
Published: February 2025

We study multiscalar theories with \text{O}(N) × \text{O}(2)O(N)×O(2) symmetry. These models have a stable fixed point in dd dimensions if NN is greater than some critical value N_c(d)Nc(d). Previous estimates of this critical value from perturbative and non-perturbative renormalization group methods have produced mutually incompatible results. We use numerical conformal bootstrap methods to constrain N_c(d)Nc(d) for 3 ≤ d < 43≤d<4. Our results show that N_c> 3.78Nc>3.78 for d = 3d=3. This favors the scenario that the physically relevant models with N = 2,3N=2,3 in d=3d=3 do not have a stable fixed point, indicating a first-order transition. Our result exemplifies how conformal windows can be rigorously constrained with modern numerical bootstrap algorithms.

Published: February 2025

Diversity management encompasses dimensions such as gender and sexual orientation, age, disabilities, nationality, ethnicity, religion, and socio-economic status (SES) and is fundamental to sustainable development, enabling higher education institutions (HEIs) to foster inclusive, equitable, and resilient academic environments. This study examines diversity management practices in seven Czech and five Ukrainian HEIs recognized as leaders in the Times Higher Education (THE) Impact Rankings. Data were obtained from university websites, SDG reports, or annual reports focusing on SDG 1, SDG 2, SDG 4, SDG 5, SDG 8, SDG 10, and SDG 16. The analysis shows that Czech universities demonstrate structured policies and stable resources, enabling them to offer comprehensive support for professional growth, gender equality, and inclusivity. Examples include sabbatical opportunities, gender-balanced organizational policies, and adaptive measures for individuals with disabilities. Conversely, Ukrainian universities exhibit remarkable resilience and adaptability, addressing challenges posed by the ongoing war. Key initiatives include supporting displaced students and veterans, restoring damaged infrastructure, and integrating inclusive education practices under wartime constraints. Despite differing contexts, both countries emphasize financial aid and scholarships as critical tools for ensuring equitable access to education. The findings underscore the importance of leveraging diversity dimensions to develop effective strategies for achieving SDGs while adapting to regional and institutional specificities.

Published: February 2025

O objetivo primário do estudo foi descrever o perfil de deglutição por meio de avaliação clínica e instrumental e o perfil nutricional de pacientes com síndrome pós-COVID-19, por sexo. Estudo ambispectivo.  A coleta de dados primários foi realizada no Ambulatório de Reabilitação pós-COVID-19 de um hospital universitário, sendo selecionados 50 indivíduos adultos que estiveram internados por COVID-19 grave. Todos foram submetidos às avaliações de deglutição (Eating Assessment Tool – 10 – EAT-10; Volume–Viscosity Swallowing Test - V-VST e videoendoscopia da deglutição - VED) e nutricionais (Mini Avaliação Nutricional- MNA e Índice de Massa Corporal - IMC). Participaram 26 mulheres (51,04 ±13,59anos) e 24 homens (55,92±10,18anos) após 4 meses da infecção aguda por COVID-19, com histórico de internação prolongada em unidade de terapia intensiva (UTI) por mais de 20 dias. Alterações na deglutição, no sexo feminino e masculino, foram identificadas no EAT-10 (53,85% - 8,33%; p=0,001); no V-VST (76,92% - 79,17%; p=0,848) e no VED (92,31% - 83,33%; p=0,651), respectivamente. Tanto as mulheres (35,41± 5,68Kg/m2) quanto os homens (31,65±4,64Kg/m2) eram obesos. O risco para desnutrição, pelo MNA, foi observado em ambos os sexos (53,85% nas mulheres e 58,33% nos homens) e 23,08% das mulheres eram desnutridas. Não foram observadas correlações entre as variáveis de deglutição com classificação do IMC (p=0,663) e com MNA (p=0,137). Nossos resultados sugerem que os indivíduos com síndrome pós-COVID-19 apresentaram risco para disfagia e obesidade, independente do sexo. Ademais, as mulheres eram desnutridas. Fica evidente a importância do atendimento oportuno das alterações de deglutição e nutrição, com o objetivo de avaliar e otimizar a reabilitação, evitando sequelas associadas.

Authors: Çimen Murat , Güven Alper
Published: February 2025

In this study, the effectiveness of using cluster analysis in determining the changes in the number of animals in the field of goat and buffalo breeding in the TRB1 region was tested. The numbers of goats and buffalos used in the research were obtained from the records kept by TÜİK between 2004 and 2023. According to the cluster analysis results, the numbers of buffalos in Elazığ and Bingöl provinces was found to be higher than Malatya and Tunceli provinces between 2004 and 2023. According to the specified years, while Bingöl province was found to be higher than other provinces in terms of the numbers of goats, it was determined that Malatya province had the lowest values. When analyzed by year, the numbers of buffalos in the provinces of the TRB1 region for the years 2004-2006 was found to be higher than the following years. In other words, it is understood that the numbers of buffalos has been decreasing in the TRB1 region since 2007. In the TRB1 region, goat numbers between 2012-2023 were found to be higher than those between 2004-2011. Accordingly, it can be said that there has been an increase in the number of goats in the TRB1 region since 2012. In the TRB1 region, appropriate regulations need to be made, taking into account the differences between provinces and years in terms of the numbers of buffalos and goats. In this study, it was seen that cluster analysis could be used successfully in determining the differences in animal numbers according to provinces and years.

COVID-19 is becoming a pandemic worldwide. The disease can cause mild to severe
symptoms. The diagnostic methods currently available include laboratory testing using RT-PCR, as
well as imaging techniques such as chest X-rays and CT scans. The most common radiological features
in COVID-19 patients are ground glass opacity (GGO), reticular changes, and consolidation.
Other features that can be found are thickening of the interlobular septa, bronchiectasis, pleural
thickening, and a crazy-paving pattern. The most common distribution is bilateral, peripheral, and
with a predominance in the middle or lower parts. Chest X-ray (CXR) examination may show abnormalities
in 75% of RT-PCR-confirmed positive cases. Although generally not recommended due
to its low sensitivity, CXR is still considered an affordable radiologic imaging technique in diagnosing
COVID-19 pneumonia. Chest CT-Scan (CCT) has a higher sensitivity in COVID-19 diagnostics
compared to CXR. On CCT examination, there is a CO-RADS classification that can help assess the
level of suspicion of COVID-19. Ultrasonography has certain advantages, especially when used in
pediatric patients.

This study investigated whether children's association skills and engagement with literate media, toys, games, and activities influence their early reading and writing abilities in kindergarten. The study included 60 participants selected by cluster random sampling, using a 2 x 2 factorial design. The results indicated that children who played with literate media scored higher in early reading and writing abilities than those who played with non-literate media. Fourth, youngsters with high association skills, playing with literated media score better than youngsters with high association skills playing with nonliterated media. Children with high association skills also demonstrated better early reading and writing abilities than those with low association skills. The study found a significant interaction between association skills and media, which influenced early reading and writing abilities differently. The study emphasizes the importance of incorporating literate media and activities that promote association skills in early childhood education to enhance children's early reading and writing abilities. It also highlights the need for teachers and parents to consider individual differences in association skills when selecting media and activities for young children. Both literate and non-literate media have an important impact when combined with different association skills, influencing children's early reading and writing abilities.

Advancing Health Care With Digital Twins: Meta-Review of Applications and Implementation Challenges (Preprint)
Authors: Ringeval Mickaël , Etindele Sosso Faustin Armel , Cousineau Martin , Paré Guy
Published: February 2025

BACKGROUND

Digital twins (DTs) are digital representations of real-world systems, enabling advanced simulations, predictive modeling, and real-time optimization in various fields, including health care. Despite growing interest, the integration of DTs in health care faces challenges such as fragmented applications, ethical concerns, and barriers to adoption.

OBJECTIVE

This study systematically reviews the existing literature on DT applications in health care with three objectives: (1) to map primary applications, (2) to identify key challenges and limitations, and (3) to highlight gaps that can guide future research.

METHODS

A meta-review was conducted in a systematic fashion, adhering to PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines, and included 25 literature reviews published between 2021 and 2024. The search encompassed 5 databases: PubMed, CINAHL, Web of Science, Embase, and PsycINFO. Thematic synthesis was used to categorize DT applications, stakeholders, and barriers to adoption.

RESULTS

A total of 3 primary DT applications in health care were identified: personalized medicine, operational efficiency, and medical research. While current applications, such as predictive diagnostics, patient-specific treatment simulations, and hospital resource optimization, remain in their early stages of development, they highlight the significant potential of DTs. Challenges include data quality, ethical issues, and socioeconomic barriers. This review also identified gaps in scalability, interoperability, and clinical validation.

CONCLUSIONS

DTs hold transformative potential in health care, providing individualized care, operational optimization, and accelerated research. However, their adoption is hindered by technical, ethical, and financial barriers. Addressing these issues requires interdisciplinary collaboration, standardized protocols, and inclusive implementation strategies to ensure equitable access and meaningful impact.

Exploring the Emotional Impact of Bullying: Insights from the Empty Chair Technique
Authors: Usakli Prof. Dr. Hakan
Published: February 2025

Bullying in schools is repeated, intentional behavior where a student uses aggression, intimidation, or exclusion to harm, dominate, or humiliate another student. The empty chair technique is a therapeutic exercise used in Gestalt therapy, developed by Fritz Perls. It involves the client imagining a person, aspect of themselves, or situation represented by an empty chair and engaging in a conversation as if the entity were present. This technique is important because it helps clients explore unresolved emotions, gain insights, and develop self-awareness by externalizing internal conflicts. To practice it, the therapist guides the client to speak to the empty chair, then switch roles by moving to the chair and responding from the perspective of the imagined entity. This study investigates the emotional experiences of twelve students who endured bullying during their primary school years, using the empty chair technique as a therapeutic intervention. The research explores participants’ feelings, coping mechanisms, and retrospective reflections on their bullying experiences. The findings illuminate the psychological effects of bullying and offer insights into the potential of the empty chair technique as a means of fostering emotional expression and healing. Implications for educators, therapists, and policymakers are discussed.

Authors: Herrera Chahua Rosmery , Ramos Zuñiga Ruth , Cárdenas Villanueva Ludwing Angel
Published: February 2025

El objetivo del estudio fue evaluar el perfil hematológico de cuyes suplementados con harina de hojas de Erythrina edulis. Las hojas de Erythrina edulis se recolectaron a tres edades de rebrote de 4, 8 y 12 meses (E4, E8, E12), se molieron en harina y se incluyeron en las dietas para cuyes al 10, 20 y 30 % (P10, P20, P30). Un total de 80 cuyes machos mejorados y destetados se distribuyeron aleatoriamente para cada dieta. Después de 56 días se recolectó sangre directamente de la vena yugular en tubos con EDTA para analizar eritrocitos, volumen corpuscular medio, hematocrito, hemoglobina, leucocitos, plaquetas y volumen plaquetario medio. Los eritrocitos y hemoglobina fueron similares entre las dietas. Los factores edad e inclusión de harina no afectaron los valores encontrados en los eritrocitos, volumen corpuscular medio, hematocrito y hemoglobina. El factor edad (E4:8.55; E8:11.92; E12:10.14 x103/uL) e inclusión de harina (P20:11.11; P30:12.08; P10:7.43 x 103/uL) provocaron diferencias en los leucocitos. Las plaquetas fueron afectadas por el factor edad (E4:391.98; E12:400.67; E8:467.08 x 103/uL) y factor inclusión de harina (P10:444.22; P20:443.05; P30:372.45 x 103/uL). El volumen plaquetario medio expuso variaciones por el factor edad (E8:11.39; E12:11.31; E4:11.90 fL). La harina de hojas de Erythrina edulis en las dietas de cuyes tiene potencial como insumo alimenticio sin alterar el perfil hematológico, lo que indicaría que los factores edad e inclusión no inducirían toxicidad.
