Assessing the Evidence Base for School-Based Promotion and Prevention Interventions: Introduction to the Series.

Schools are an important component in the mental health system of care for youths. Teachers and other school staff have unique opportunities to promote emotional wellness and prevent mental health conditions. Although numerous programs are available, identifying evidence-based and effective options is a significant challenge. This introduction lays out the rationale and methodology of the Assessing the Evidence Base (AEB) Series, a collection of systematic reviews of school-based mental health promotion and prevention approaches recommended by the National Academies of Sciences, Engineering, and Medicine for students in kindergarten through grade 12. Authors of the current AEB Series used the rating criteria derived from the 2014 AEB Series, which provided systematic reviews of a wide spectrum of interventions for mental and substance use disorders. Like its predecessor, the current series upholds a high standard of scientific rigor while ensuring that the information is easily accessible to various stakeholders in education, behavioral health, and communities. It describes the universal features included in each systematic review, such as a rating of the level of evidence for interventions, intervention program components, identification of interventions that have yielded positive outcomes for students from underserved populations, and a review of cost data. The AEB systematic reviews will serve as an important tool for decision makers involved in managing limited resources for various programs in school-based mental health services by synthesizing large bodies of research for use by leaders in education and behavioral health.

High performance of an innovative cable-in-conduit conductor with CWS cable pattern

Abstract Cable-in-conduit conductors, known as CICCs, were developed for constructing superconducting coils in tokamak fusion reactors. To achieve large currents in high magnetic field, CICCs were utilized with a short-twist-pitch (STP) cable pattern to prevent irreversible performance degradation, but also inducing higher AC losses. Institute Of Plasma Physics Chinese Academy Of Sciences (ASIPP) designed and manufactured three innovative CICCs, all featuring CWS (copper wire with a short-twist-pitch wound around superconducting strands with a long-twist-pitch) structure to increase both the current density and structure stiffness of CICC cable. These CICCs had the same new CWS cable pattern but the Nb3Sn superconducting strands were from different suppliers. All samples were subsequently tested under electromagnetic cycling tests in SULTAN. For similar electromagnetic performance degradation, the Lorentz load threshold of the CWS cable pattern exhibited to be higher than that of STP cable pattern. Moreover, the AC losses of CWS were 15% lower than that of STP cable pattern for low frequencies of the applied alternating magnetic field. Both results indicated that the CWS cable pattern has a higher margin of engineering safety and lower AC losses than STP cable pattern under the target operating conditions. This provides new insights in finding solutions for optimizing the CICCs’ cable pattern and preventing its electromagnetic performance degradation.

„The Black Box" by George Stocking

Three years before his death on July 13, 2013, George William Stocking, widely regarded as the discipline's "greatest historian of anthropology," wrote an autobiography and memoir entitled Glimpses into My Own Black Box: An Exercise in Self-Deconstruction(2010). The book was published as part of the famous History of Anthropology (HOA) edition, which Stocking started at The University of Wisconsin Press (1983) and edited for two decades. This paper is based on the understanding of the American theoretician of autobiography, William Howarth, who posited that autobiography in literary (and scientific) writing is akin to what self-portrait is in painting. In the introductory chapter of the work, biographical data are presented that bring the character and work of George William Stocking closer to the domestic, Serbian readership (his second marriage to the sociologist Carol Bowman; their stays in Yugoslavia). This is followed by a description of the two main phases in Stocking's life and work: the formative period in his intellectual development and the mature age, known as the "Chicago years", spent in the Departments of History and Anthropology. Bearing in mind the main elements of the autobiographical strategy – character/self-portrait, technique (rhetoric and writing style), and the theme presented by the author's work-text – Stocking's book thematizes the life story, professional and scientific history (history of anthropology) from the position of both a witness and the one of the creators of written histories of the discipline and biographies of its practitioners and theorists. His writing technique is characterized by self-reflection and scientifically argued discussions on anthropological, historical and political topics and problems. Despite the significant influence his writing and edition of the HOA has had in anthropology, social sciences and humanities, the autobiographer problematizes his relationship to the two disciplines that shaped him as a scientist, highlighting his ambivalent position within them. In spite of the objective indicators of professional success, such as prestigious recognitions, awards, a secure position at the University and the Academy of Arts and Sciences, and a comfortable civic life filled with trips, conferences and guest appearances at important American and British scientific research institutions, the subjective experience of "double non-belonging" or rather, liminality, is the leitmotif that colors his self-portrait and the meaning of the text as a whole. The main features of the work, such as its discursive style of narration and description, striving for objectivity and honesty (self-disclosure and „self-deconstruction“), anxiety regarding one's own place, role and importance in science, as well as, at times, a resigned or elegiac tone, especially at the end of the book, i.e. towards the end of his life, provide the basis to include Stocking's strategy in a hybrid type with elements of those two categories that Howarth calls "rhetorical" and "poetic" confession.

One Hundred and Thirty-Five Years of Ornithology in Bulgaria: The Role of the National Museum of Natural History at the Bulgarian Academy of Sciences in the Development of Ornithology in Bulgaria—Representatives, Collections and Achievements

This 135-year period (1889–2024) includes the work of 12 curators of the ornithological collections. Their major contributions and most-significant ornithological publications are also presented.

Spatio-Temporal Changes of Arable Land and Their Impacts on Grain Output in the Yangtze River Economic Belt from 1980 to 2020

The “Yangtze River Economic Belt Development Strategy” is one of China’s three major national development strategies. Enhancing the protection and quality of arable land in the Yangtze River Economic Belt (YEB) is pivotal for fostering regional growth. In this study, land use data spanning the years 1980 to 2020 in the YEB were extracted from the national land use database maintained by the Resource and Environment Data Center of the Chinese Academy of Sciences. Employing Geographic Information System (GIS) spatial analysis techniques and arable land change metrics, the study delineated the spatiotemporal characteristics of arable land alterations across the YEB for the period. Additionally, using grain output data at the prefecture level from 2011 to 2020, the paper calculated provincial grain output to analyze the impact of arable land changes over the last four decades on grain output. The findings revealed that: (1) From 1980 to 2020, the total arable land area in the YEB decreased by approximately 41,775 square kilometers, with the most significant decrease occurring in the downstream region. (2) From 1980 to 1990, the primary factor contributing to the decrease in arable land area was the expansion of water bodies, while from 1990 to 2020, the principal reason for the reduction in arable land area was the expansion of construction land. (3) From 1980 to 2020, the decrease in arable land area resulted in a net reduction of approximately 25.12 million tons in total grain output, with the largest decline observed in the downstream regions and the smallest decline in the upstream regions. (4) Consistent with the trends in arable land area reduction, the main reason for the decline in grain output from 1980 to 1990 was the expansion of water bodies encroaching upon arable land, whereas from 2000 to 2010, the primary cause of arable land reduction was the expansion of construction land areas. In conclusion, the research suggested that over the past four decades, the primary driver behind the reduction in arable land within the YEB has been the expansion of construction land areas. Particularly noteworthy was the period from 2000 to 2010, during which the impact of arable land reduction on grain output was most pronounced. This period coincided with the rapid economic development and accelerated urbanization process within the YEB.

New productive pear variety Favoritka

The results of the selection and variety study of pears in the conditions of the Southern Urals are considered. At the South Ural Research Institute of Horticulture and Potato Growing, a branch of the Federal State Budgetary Institution Urfanits Ural Branch of the Russian Academy of Sciences, breeding work was carried out to improve the assortment of pears for the Ural region. As a result of many years of breeding work, the range of fruit and berry plants was replenished with a new pear variety, Favoritka, which in 2022 was included in the State Register of Breeding Achievements approved for use. In the process of breeding work, the winter hardiness of pear varieties in the harsh climatic conditions of the Chelyabinsk region was studied, as a result it was noted that infield conditions when the temperature dropped to -40 ° C, freezing of trees of local varieties did not exceed 1 point. An assessment was made of the yield of local varieties, among which the following varieties stand out: Vekovaya, Myth, Favoritka, and Zolotoy Shar, with an average yield of 24 - 28 kg per tree. The economic indicators of the Favoritka pear variety (profitability level of 253.5%) indicate its suitability for cultivation in both industrial and amateur gardening in the Ural region. A pomological description and assessment of the economic usefulness of the new Favoritka pear variety are presented, which combines large fruit (fruit weight can reach 340 g), high winter hardiness, productivity, resistance to abiotic and biotic stressors (not affected by scab, resistant to pear gall mite), has fruits of excellent taste, suitable for fresh consumption, as well as for processing (preparing jams, preserves, compotes, etc.). The variety is in demand among the population and is of interest as a source of giant fruit in further breeding work.

ARTURO ISSEL (1842–1922): THE MAN FROM GENOA BEHIND THE TYRRHENIAN STAGE OF THE PLEISTOCENE

ABSTRACT Arturo Issel (1842–1922) introduced the regional Tyrrhenian stage of the late Pleistocene in 1914. This still stands within modern stratigraphic classification as an Italian Marine Stage for the Mediterranean Sea marking the base of the Late Pleistocene underlining the scientific importance of Issel's research within the geological sciences. This paper provides a short overview of the career and the wide-ranging interests of this Italian geologist and naturalistic traveller in order to provide a context to the knowledge and research experience behind his stratigraphic work. As university professor in Genovese society during the late nineteenth and early twentieth centuries, he played an important role in scientific instruction, exploration and research contributing to the popularization of science through museum collections and publications and in the application of such knowledge within public office both in Liguria and within Italy. He formed part of the Italian delegation at International Geological Congresses and held membership of the most outstanding geological societies and scientific academies of the time.

[Study on the inhibitory and pro-apoptotic effects of different concentrations of total tanshinone alone and in combination with tyrosine kinase inhibitors on human myeloid leukemia cell lines].

Objective: To explore the effect and investigate the molecular mechanism of different concentrations of total tanshinones alone and in combination with tyrosine kinase inhibitors (TKIs) on the proliferation inhibition and apoptosis of human myeloid leukemia cell lines. Methods: K562 and Kasumi-1 cell lines were purchased from the Shanghai Cell Bank of the Chinese Academy of Sciences, and the TKIs-resistant strain K562/T315I cell line was constructed in Molecular Medicine Research Center, Beijing Lu Daopei Institute of Hematology. Logarithmic growth phase cells were taken and divided into intervention groups with total tanshinone of 0, 2.19, 4.38, 8.75, 17.50 and 35.00 μg/ml intervention groups, which were inoculated in 96-well plates at a density of 1×104 cells/well and exposed to the drug for 24 h, and a control group treated with dimethyl sulfoxide was also set up simultaneously. All experiments were repeated independently 3-5 times. The proliferative activity of the cells was assessed using the CCK-8 assay, the apoptotic rates were measured by flow cytometry, and the expression levels of apoptosis-regulating proteins Bcl-2 and Bax were analyzed by Western blotting. The cell lines treated and untreated with total tanshinone were subjected to transcriptome sequencing and gene set enrichment analysis to identify differentially expressed genes. Results: The half-inhibitory concentration (IC50) values of 8.75 μg/ml total tanshinone at 24 h for K562, K562/T315I and Kasumi-1 cells were (4.11±0.02), (4.95±0.04) and (3.98±0.01) μg/ml, respectively. When combined with 0.25 μmol/L imatinib, 8.75 μg/ml total tanshinone could enhance the induction of apoptosis effects on K562 and K562/T315I cell lines. After being treated with 4.38, 8.75, and 17.50 μg/ml of total tanshinone for 24 h, compared with the control group, total tanshinone upregulated the expression level of Bax protein, downregulated the expression level of Bcl-2 protein, and decreased the Bcl-2/Bax ratio (all P<0.05). Total tanshinone inhibited the proliferation-related signaling pathway and DNA damage repair pathway of myeloid leukemia cell lines, and activated the signaling pathway that induces apoptosis in leukemia cells. Conclusion: Different concentrations of total tanshinoneinhibites proliferation and promote apoptosis in K562, Kasumi-1 and TKIs-resistant K562/T315I cell lines, and further enhance the anti-leukemic effect when combined with TKIs.

Optical-spectroscopic and isotope-geochemical characteristics of zircons from diamond-bearing placers in Yakutia as indicators of diamond ore bodies

Research subject. Zircon grains from diamond placers of the Molodo and Ebelyakh rivers of the Yakut Arctic. Aim. To study the indicator characteristics of zircon to determine sources of diamonds and ways of their transfer to placers; to analyze optical-spectroscopic and isotope-geochemical parameters of zircon grains, their microelemental, U-Pb, and Lu-Hf isotope composition. Materials and methods. A LA-ICP-MS analysis of the U-Pb isotopic and trace element composition of zircon was carried out using a NexION 300S mass spectrometer with an NWR 213 attachment. An analysis of the Lu-Hf isotope system was carried out using a Neptune Plus mass spectrometer with an NWR 213 attachment, located in a room of cleanliness class 7 ISO at the Geoanalitik Center for Collective Use (IGG Ural Branch of the Russian Academy of Sciences, Ekaterinburg). Raman spectra were obtained using a LabRAM HR800 Evolution confocal spectrometer. CL spectra were obtained using a Jeol JSM6390LV scanning electron microscope equipped with a Horiba H-CLUE iHR500 attachment. Results. The local optical spectroscopic characteristics (Raman spectra and catholuminescence) of zircon grains were established, which made it possible to substantiate the conclusion about their high crystallinity and homogeneity (monochrony), as well as to select international zircon standards with similar characteristics for use in LA-ICP-MS analysis to ensure similar conditions for evaporation of the substance and fractionation parameters of the U and Pb elements. LA-ICPMS data on the microimpurity, U-Pb and Lu-Hf isotopic composition of zircon grains from diamond placers, as well as the dose values of their self-irradiation, are presented. Conclusions. The obtained U-Pb dating contributes to reconstructing a more precise history, character, and sequence of manifestation of kimberlite magmatism, tectonic processes, and migration routes of kimberlite material and diamonds across the Siberian craton, within the Yakut kimberlite province.

The Influence of the Teacher’s Psycho-Physiological States on the Development of Professional Competencies in the Course of the Military Aggression

The aim of the article is to determine the specifics of the impact of the correctional programme of psycho-physiological conditions on the development of the professional competence of general secondary school teachers. The Diagnostics of Mental States of the National Academy of Sciences and the Impact of Event Scale - Revised (IES-R) were used to obtain reliable data on the psycho-physiological state of the individual. A specialized online test for teachers was used to obtain data on the teachers’ competence aimed at determining informational competence, testing to determine the teacher’s subject methodical competence, observation of communicative competence. A formative experiment was planned and conducted. It was established that average indicators of psycho-physiological state prevail among teachers. The positive impact of the developed corrective programme on the teachers’ activity and mood was proved. It was concluded that the change in the psycho-physiological states of “invasion” and “avoidance” significantly depends on current social conditions, in particular, on the stability of the safety component. It was found that the correctional programme levelled the connections between the teachers’ subject methodical competence and the current psycho-physiological state. It was established that the teachers’ communicative competence continues to correlate after the completion of the programme with psycho-physiological comfort and general emotional background. In general, we can talk about the relative effectiveness of the developed corrective programme. The obtained results can be used to optimize programmes of continuous postgraduate education in the context of the development of resistance to the stresses of wartime. The prospects for further research are expanding the arsenal of methods for studying the teachers’ psycho-physiological state and clarifying gender differences in the teachers’ experience of stress.

224 Influence of gender on animal science research funding from the National Institute of Food and Agriculture

Abstract According to the National Academies of Sciences, Engineering, and Medicine, females and males in science disciplines obtain bachelor of science degrees at or near parity, yet females are not equally represented in academic faculty positions. This is true for agricultural field including the animal sciences. The National Institute of Food and Agriculture (NIFA) administers the Agriculture and Food Research Initiative (AFRI) at USDA, a flagship competitive grants program that fund research, education, and extension efforts with a total appropriation of $455 million in 2023. Our objective was to determine the difference between genders for submission rates (i.e., number of standard and seed grant applications submitted), success rates (i.e., number of grant award/number of applications submitted), and peer reviewers of grant applications in the main animal related AFRI program area priorities. All applications submitted to AFRI programs in animal genomics, reproduction, health, nutrition and growth, and welfare during 2013 to 2022 were evaluated. Gender was assigned to Project Directors (PD) and peer reviewers using first names as input into Gender API software (Gender-API.com; Passau, Germany) with ≥ 95% accuracy and ≥ 20 database occurrences used as quality filters and binary outcomes only (i.e., male or female). Effect of gender on submission rates, success rates, and peer review panel compositions were then analyzed using Pearson’s Chi-squared tests with P ≤ 0.05 considered significant. A total of 3,392 applications were submitted, of which 2,579 (76%) PD genders were assigned and analyzed further. Overall, the proportional submission rate for females was 28% and for males was 72%. Submission rates for females increased (P = 0.0497) over time ranging from 22% in 2013 to 33% in 2021. Submission rates differed by gender across programs (P &amp;lt; 0.0001) and ranged from 22% female in animal reproduction to 48% female in animal welfare. Overall, the funding success rate was 22% and did not differ between genders (P = 0.9826). Success rates did not differ between genders over time (P = 0.4691), but differences among programs approached significance (P = 0.0670). Across 53 panels, 42% of panelists were female; no differences were identified for the proportion of female panelists over time (P = 0.9762) or by program (P = 0.7028). Females submitted less than one-half as many applications as males, but the proportion of submissions by females increased over time. This trend remained consistent despite challenges of relocation of NIFA and COVID-19 during this time. Funding success rates did not differ by gender, but some variation was observed across programs. Overall, the proportion of NIFA panelists who were female exceeded the proportion of applications submitted by females. These results indicate that although differences in gender existed for application submission rate and panel composition, these differences did not impact funding success rate of applications in animal science programs at NIFA, which did not differ between genders.

Electrocardiographic abnormalities in patients with microtia

The main objective of this study was to investigate the incidence and characteristics of electrocardiographic abnormalities in patients with microtia, and to explore cardiac maldevelopment associated with microtia. This retrospective study analyzed a large cohort of microtia patients admitted to Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, from September 2017 to August 2022. The routine electrocardiographic reports of these patients were reviewed to assess the incidence and characteristics of abnormalities. The study included a total of 10,151 patients (5598 in the microtia group and 4553 in the control group) who were admitted to the Plastic Surgery Hospital of Peking Union Medical College. The microtia group had a significantly higher incidence of abnormal electrocardiographies compared to the control group (18.3% vs. 13.6%, P < 0.01), even when excluding sinus irregularity (6.1% vs. 4.4%, P < 0.01). Among the 1025 cases of abnormal electrocardiographies in the microtia group, 686 cases were reported with simple sinus irregularity. After excluding sinus irregularity as abnormal, the most prevalent abnormalities was right bundle branch block (37.5%), followed by sinus bradycardia (17.4%), ST-T wave abnormalities (13.3%), atrial rhythm (9.1%), sinus tachycardia (8.3%), and ventricular high voltage (4.7%). Less common ECG abnormalities included atrial tachycardia (2.1%), ventricular premature contraction (2.4%), and ectopic atrial rhythm (1.8%). atrioventricular block and junctional rhythm were present in 1.2% and 0.9% of the cases, respectively. Wolff Parkinson White syndrome and dextrocardia had a lower prevalence, at 0.6% and 0.9%, respectively. The occurrence of electrocardiographic abnormalities in microtia patients was found to be higher compared to the control group. These findings highlight the potential congenital defect in cardiac electrophysiology beyond the presence of congenital heart defect that coincide with microtia.

Current problems in the field of structure, properties of minerals and methods of their investigation

The main goal of research into the structure and properties of minerals, as well as their crystal chemistry and physics, consists in obtaining fundamental information about the actual atomic and electronic structure of mineral objects and physical regularities of their transformations under the influence of external factors (temperature, pressure, radiation, and environmental chemistry). Such information forms the basis for mineral typification and restoration of mineral crystallization conditions and their evolution in a certain geological situation. This information is widely used in petrogenetic and geochronological constructions. Such studies are also relevant to the development of nature-like technologies for obtaining new promising functional materials. Knowledge of the structure, crystal chemistry, and physics of minerals, typomorphism of their spectroscopic properties, as well as the development of analytical techniques and methods for the synthesis of mineral-like materials are of particular significance. This thematic issue of the Lithosphere journal aims to review of these problems in the context of the materials reported at the XIII All-Russian Scientific Conference “Minerals: Structure, Properties, Research Methods” held in 2023 at the Institute of Geology and Geochemistry of the Ural Branch of the Russian Academy of Sciences in Yekaterinburg.

The burden and management competency of cardiomyopathies in China: a nationwide survey study

The public health burden of cardiomyopathies and competency in their management by health agencies in China are not well understood. This study adopted a multi-stage sampling method for hospital selection. In the first stage, nationwide tertiary hospital recruitment was performed. As a result, 88 hospitals with the consent of the director of cardiology and access to an established electronic medical records system, were recruited. In the second stage, we sampled 66 hospitals within each geographic-economic stratification through a random sampling process. Data on (1) the outpatient and inpatient visits for cardiomyopathies between 2017 and 2021 and (2) the competency in the management of patients with cardiomyopathies, were collected. The competency of a hospital to provide cardiomyopathy care was evaluated using a specifically devised scale. The outpatient and inpatient visits for cardiomyopathies increased between 2017 and 2021by 38.6% and 33.0%, respectively. Most hospitals had basic facilities for cardiomyopathy assessment. However, access to more complex procedures was limited, and the integrated management pathway needs improvement. Only 4 (6.1%) of the 66 participating hospitals met the criteria for being designated as a comprehensive cardiomyopathy center, and only 29 (43.9%) could be classified as a primary cardiomyopathy center. There were significant variations in competency between hospitals with different administrative and economic levels. The health burden of cardiomyopathies has increased significantly between 2017 and 2021 in China. Although most tertiary hospitals in China can offer basic cardiomyopathy care, more advanced facilities are not yet universally available. Moreover, inconsistencies in the management of cardiomyopathies across hospitals due to differing administrative and economic levels warrants a review of the nation allocation of medical resources. This work was supported by the Chinese Academy of Medical Sciences (CAMS) Innovation Fund for Medical Sciences (2023-I2M-1-001) and the National High Level Hospital Clinical Research Funding (2022-GSP-GG-17).

Unveiling the Missing Link: Women in Stem Leadership – A Comprehensive Review

This paper extensively examined the representation of women in Science, Technology, Engineering, and Mathematics (STEM) within Malaysia, contextualized globally and historically. Existing research affirms the growing presence of women in the workforce (Gupta, 2020; National Academies of Sciences &amp; Medicine, 2020), their progress in higher education (Manongsong &amp; Ghosh, 2021; Vietze et al., 2022), their presence in professional and managerial roles (Burton et al., 2020; Evans &amp; Maley, 2021), and their successful elevation to CEO positions (Dadanlar &amp; Abebe, 2020). However, women continue to be significantly underrepresented in leadership positions, particularly within STEM firms (Hideg &amp; Shen, 2019; National Academies of Sciences &amp; Medicine, 2020). Young Malaysian women excel in both academic and extracurricular STEM activities from primary to university. Despite this gender equity achieved in STEM education, with 29% of tertiary engineering graduates and 57% of science degree holders being female, only 6% of women pursue careers as STEM professionals (Looi, 2022). Additionally, slightly over 4% of women hold leadership roles in technology firms in Malaysia (Amin &amp; Tan, 2018). Using social constructivist and feminist theories, this analysis examines how societal and environmental factors affect girls’ performance in math and science. Educators and parents play a vital role in providing crucial support. This study also highlights a major research gap, particularly in understanding where qualified women in STEM go, especially within Malaysia.

Evaluating westward and eastward propagating mesoscale eddies using a 1/10° global ocean simulation of CAS-LICOM3

This research evaluates the performance of CAS-LICOM3 (Chinese Academy of Science, State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysical Fluid Dynamics/Institute of Atmospheric Physics (LASG/IAP) Climate system Ocean Model, version 3) in simulating global coherent mesoscale eddies by comparison to satellite altimeter observations. The simulations of westward and eastward propagating eddies (WPEs and EPEs) and cyclonic and anticyclonic eddies (CEs and AEs) are separately analyzed. The results demonstrate that the simulated spatial-temporal variabilities in global mesoscale eddies agree roughly with the satellite observations. CAS-LICOM3 also reproduces the distinctive features between WPEs and EPEs or between CEs and AEs. However, some systematic biases are found. Globally, CAS-LICOM3 simulates a less frequent and weaker mesoscale eddy field than is observed. WPEs contribute more to these global biases than do EPEs. EPEs are relatively better reproduced than WPEs, exhibiting smaller underestimations and even overestimations in the energetic western boundary current and Antarctic circumpolar current regions. The simulation results for CEs resemble those of AEs, but AEs are comparatively less biased than CEs. These findings provide a basis for improving low-resolution and eddy-resolving ocean general circulation models (OGCMs) and developing submesoscale-resolving OGCMs.

Revisiting the IOM Reports and Envisioning a Promising Future for Public Health.

Two public health reports from the National Academies of Sciences, Engineering, and Medicine published in 1988 and 2003 by the Institute of Medicine continue to resonate. The COVID-19 pandemic highlighted the need for a robust and adequately funded public health system that has political and public support as well as strong connections to health care and other sectors. However, a spate of recent assessments of the nation's public health infrastructure shows continuing gaps in funding, workforce, capacity, and other dimensions. There are reasons for optimism and opportunities for progress in public health in the third decade of the 21st century. There is great promise in cross-sector partnerships and in embracing the "public" in public health by building power with communities in health improvement efforts and in decision-making.

Digital resources in teaching Russian to Chinese students outside of the language environment

Introduction. Relations between China and Russia are becoming increasingly close, resulting in a high demand for Russian language specialists in the labor market. The lack of a language environment in Chinese universities is a pressing problem that teachers would like to solve. Therefore, the active implementation of digital technologies will undoubtedly compensate for this deficiency. The purpose of the study is to analyze the use of Chinese internet resources in teaching Russian language in Chinese universities. Materials and Methods. The study involved undergraduate, postgraduate and doctoral students studying in the fields of "Russian as a Foreign Language", "Philology", "Linguistics" and "Russian Literature". A total of 117 respondents from nine higher education institutions in Russia and China. These institutions include Heilongjiang Institute of Foreign Languages, RUDN, Moscow State University, Moscow State Pedagogical University, Institute of China and Modern Asia of the Russian Academy of Sciences, Bauman Moscow State Technical University, Russian State University of Tourism and Service, Inner Mongolia University, and Yili Pedagogical University. The research methods employed in the study were analysis of scientific and scientific-methodological literature, observational (monitoring of online and distance learning), diagnostic (interviews with teachers, student surveys), and statistical analysis. Results. It was found that Chinese students do not know which form of education is most preferable outside of the Russian-speaking environment (35.9% – online, 37.61% – in-person, 38.46% – blended). However, respondents (67%) stated that various online resources provide significant help in learning the Russian language. The most popular programs and platforms were Chinese Dingding and Tencent Meeting, international Microsoft Teams and Zoom. Not all Russian-language dictionaries are available online for Chinese people, which is why the share of translation programs assisting in learning Russian language has increased (over 70%). The most frequently used Chinese dictionary was "Qianyiciba" (62%), and the most popular websites include Google Translate, Yudao Translator, Baidu Translate, and Bilibili. It has been proven that among the main problems hindering the process of learning Russian language in online and distance learning formats, psychological discomfort, lack of communication, increase in independent work, and individualization in learning considering the personal needs of students should be highlighted. Conclusion. The results obtained make it possible to determine the prospects for using digital resources in teaching Russian as a foreign language to Chinese students outside of the language environment.

Application of High-Frequency Ultrasound to Evaluate Forehead Filling Materials.

In recent years, soft tissue materials have been applied as forehead fillers. Some filling materials need to be removed or refilled in a timely manner in certain situations; therefore, it is important to develop a method to identify the location and type of filling materials. This study summarizes the imaging findings of different filling materials under high-frequency ultrasound, providing a reference for clinical treatment. We screened facial ultrasound images performed at the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences from April 2015 to July 2023 and classified and summarized the types of frontal filling materials and their imaging results. This study included ultrasound imaging results from 114 patients, including 39 with hyaluronic acid (HA) filling, 45 with polyacrylamide hydrogel (PAG) filling, 14 who received autologous fat transplantation, 2 who received prosthesis implantation, 2 who received both HA and PAG filling, and 12 who received silicone oil filling. HA mainly manifests as an anechoic zone on ultrasonography, with images divisible into four types. PAG primarily presents as fine punctate echoes, divisible into five types. Fat transplantation presents as a low-echo area with uneven density, divisible into five types. Finally, the silicone oil-filling material appears as a cloud-like high echo on the forehead, visible throughout the entire skin layer, and unclear imaging in deep tissues. High-frequency ultrasound is a safe and reliable method to evaluate the type and position of forehead filling materials, which can be easily applied in clinical practice.
