Individual and molecular risk factors for the development of rheumatoid arthritis
Authors: Kucharska-Lusina Aleksandra
Published: December 2024

Rheumatoid arthritis is a chronic autoimmune disease of the joints of unknown etiopathogenesis. It affects between ~0.5 and 1% of the total population and occurs 2–3 times more often in women than in men. Several antibodies have been identified in the serum of patients with RA, including rheumatoid factors (RF), anti-citrullinated protein antibodies (ACPA) and anti-carbamylated protein antibodies. These autoantibodies can form immune complexes in the joints, leading to inflammation and damage to the articular cartilage. A characteristic symptom of advanced RA is persistent inflammation of the synovium, which usually affects peripheral joints in a symmetrical way. The exact aetiology of RA is unclear,it is known to be a multifactor disease in which a complex interplay between the host and the environment determines the overall risk of being susceptible to the disease, as well as its persistence and severity. Below we present the RA risk factors including main individual risk factors as hormonal factors, hereditery factors, epigenetic factors as well as the risk of concomitant environmental factors of RA as diet, cigarettes and alcohol abuse. Environmental contaminants, socio-economic factors and molecular mechanisms of RA known so far.

Authors: Ngando Black Charles
Published: December 2024

Cet article explore les défis auxquels les Chief Data Officers (CDO) sont confrontés pour aligner leurs initiatives de gouvernance des données sur les objectifs stratégiques de leur organisation. Il met en évidence que le modèle d'implémentation actuel, plutôt axé sur des aspects techniques, limite l’impact stratégique de ces initiatives. Il creuse l'écart entre les attentes de la direction, parfois implicites, et les résultats obtenus. A partir de perspectives académiques et des retours d’expérience, cet article propose un modèle de gouvernance intégrée, dans lequel les actions tactiques et opérationnelles se connectent directement aux priorités stratégiques. Ce modèle offre aux praticiens des avantages concrets en termes de mise en œuvre, d’impact et de pilotage des initiatives. Il contribue aussi à la recherche sur l’alignement stratégique de la gouvernance des données.

Authors: Homa Agostinho Iaqchan Ryokiti
Published: December 2024

O estudo destaca o papel dos simuladores na Educação, como ferramentas didáticas no processo de aprendizagem, integrados aos princípios da abordagem educacional STEM (Ciências, Tecnologia, Engenharia e Matemática). O objetivo foi desenvolver simuladores digitais para uso integrado a sequências didáticas, permitindo que os alunos visualizem situações reais, colocando em prática seus conhecimentos teóricos ao observar e testar suas conjecturas, com foco na Trigonometria. Os simuladores, desenvolvidos com GeoGebra, foram organizados em três atividades independentes com diferentes graus de complexidade, focando na compreensão do espaço e das ações que um braço robótico deve executar. Por não ser uma pesquisa aplicada, os resultados são os próprios simuladores como objetos de aprendizagem disponíveis para uso livre. O estudo mostra que é possível oferecer uma alternativa prática e imersiva para a Educação STEM, ajudando os alunos a aplicarem conhecimentos teóricos em situações reais utilizando simuladores.
Youth Violence in Urban Ethiopia: Forms, Risk Factors and Preventive Mechanisms in Hawassa and Shashemene Cities
Authors: Birru Addis Zena
Published: December 2024

Youth violence negatively impacts physical, emotional, and social well-being, hindering development, decision-making, learning, and relationships. Holistic and interdisciplinary approaches are needed to mitigate this issue. This research aims to investigate forms, risk factors, and preventive mechanisms of youth violence in Hawassa and Shashemene cities. The research utilized a cross-sectional descriptive design with a mixed-method approach. The study included 400 survey respondents, 16 focus group discussants across two sessions, and 7 in-depth interviewees. As the findings reveal, youth involvement in violence spans from perpetration to victimization. Among the total respondents, 289 self-reported that they have perpetrated various forms of physical, verbal, sexual, economic, and media violence within the past 12 months. The primary reported risk factors for youth violence include attitudes that condone violence (64.25%), insufficient parental control (59%), elevated rates of unemployment (67.25%), and a fragile rule of law (81.25%), which respectively represent the leading factor from the individual, relational, community, and societal risk domains as per the social-ecological model. The findings indicate that institutional and community-based efforts to address and mitigate the issue remain in their early stages. The study areas lack nearly all essential elements of youth violence prevention and intervention programs. The study concludes that youth violence is a more visible issue that affects both society and the youth in the study areas. Without preventive efforts, the highlighted risk factors may further increase the likelihood of youth engagement in violence. Thus, the study recommends the establishment of integrated and inclusive programs and strategies to effectively address the problem such as community awareness campaigns, parental counselling services, school-based interventions, and strengthening the capacity of relevant institutions among others

Authors:   Russian State University of Justice, Moscow, Russia, Prostoserdov Mikhail A.
Published: December 2024

A study was conducted on the digitalization of justice as an actual and promising area, which involves the introduction of information technology in every single aspect of justice activities. In the course of the study, the author comes to the conclusion about a possible variant of the development of digital justice in Russia – a “digital assistant judge”. Investigating this issue, the author identifies a problem that prevents the introduction of the concept of “digital assistant to a judge” – the problem of correlating alternative sanctions of criminal law norms with dispositions providing for alternative compositions of crimes. At the end of the study, the author concludes that in order to implement the concept of a “digital assistant to a judge”, criminal law must comply with the requirements of machine-readable legislation, and suggests specific measures.

Authors: Hu Dan , Li Yue , Zhang Hua , Wang Lian-Lian , Liu Wen-Wen , Yang Xin , Xiao Ming-Zhao , Zhang Hao-Ling , Li Juan
Published: December 2024

BACKGROUND

Return to work (RTW) serves as an indication for young and middle-aged colorectal cancer (CRC) survivors to resume their normal social lives. However, these survivors encounter significant challenges during their RTW process. Hence, scientific research is necessary to explore the barriers and facilitating factors of returning to work for young and middle-aged CRC survivors.

AIM

To examine the current RTW status among young and middle-aged CRC survivors and to analyze the impact of RTW self-efficacy (RTW-SE), fear of progression (FoP), eHealth literacy (eHL), family resilience (FR), and financial toxicity (FT) on their RTW outcomes.

METHODS

A cross-sectional investigation was adopted in this study. From September 2022 to February 2023, a total of 209 participants were recruited through a convenience sampling method from the gastrointestinal surgery department of a class A tertiary hospital in Chongqing. The investigation utilized a general information questionnaire alongside scales assessing RTW-SE, FoP, eHL, FR, and FT. To analyze the factors that influence RTW outcomes among young and middle-aged CRC survivors, Cox regression modeling and Kaplan-Meier survival analysis were used.

RESULTS

A total of 43.54% of the participants successfully returned to work, with an average RTW time of 100 days. Cox regression univariate analysis revealed that RTW-SE, FoP, eHL, FR, and FT were significantly different between the non-RTW and RTW groups (P < 0.05). Furthermore, Cox regression multivariate analysis identified per capita family monthly income, job type, RTW-SE, and FR as independent influencing factors for RTW (P < 0.05).

CONCLUSION

The RTW rate requires further improvement. Elevated levels of RTW-SE and FR were found to significantly increase RTW among young and middle-aged CRC survivors. Health professionals should focus on modifiable factors, such as RTW-SE and FR, to design targeted RTW support programs, thereby facilitating their timely reintegration into mainstream society.

In connection with the changing needs for professional personnel, the higher education system offers, along with traditional specialties, an ever-increasing list of new areas of training. High school students, future applicants, and their parents often cannot quickly navigate new specialties. In addition, modern high school students are characterized by a decrease in interest in higher education, social alienation, and the reproductive nature of the knowledge they receive. Therefore, the article proposes a set of principles that should underlie partnership interaction between educational organizations – schools and universities. Goal. Identification of pedagogical principles on the basis of which the construction of interaction between schools and universities will be effective.

Materials and methods. The materials of the article are based on the results of the analysis of scientific literature on the problem of organizing partnership interaction between institutions, as well as on the data of a survey of school and university teachers conducted in Krasnodar and Stavropol.

Results and discussion. The basic principles of establishing the process of interaction between school and university are defined. They are variability of education, universality, multidimensionality, consistency, integration of resources of interacting educational institutions, cooperation, integrity, congruence, and mutual benefit. The problems of building interaction between school and university are highlighted.

Conclusion. Interaction between school and university ensures high-quality implementation of a number of areas: subject training of schoolchildren (specialized school), career guidance work, focus on obtaining higher education, adaptation of students to studying at a university, and obtaining primary knowledge about the profession. Pedagogical principles of building interaction between school and university contribute to the effectiveness of this process.

“Sibling brothers Georgians... come from the land of the Black Sea army”: on the environment of the historian I.D. Popko
Authors:   North-Caucasus Federal University, Dubinin I. V.
Published: December 2024

Introduction. The history of Russia, in particular the North Caucasus, consists not only of various testimonies and facts, but also of the destinies and biographies of people. Some historical characters remain in history, others disappear into the “depths of the ages”, but there are still others about whom there are brief mentions in letters, diaries and documents. There are people who have made a significant contribution to culture and history, but the memories of them are erased from people’s memory. Two brothers, Karp and Ivan Gruzin, can also be attributed to such historical characters.
Materials and Methods. Based on documents stored in the archives of Kiev and Krasnodar, as well as printed sources of the XIX – the beginning of the XX c. an attempt is made to recreate the biography of the brothers and trace the details of their complex and difficult life path in the context of the history of the early XIX century.
Analysis. The focus was on the fate of two representatives of the Black Sea Cossacks, who managed to change their fate, graduate from the Kiev Theological Academy, become teachers of philosophy and Hebrew there, not to lose heart after being dismissed due to disagreements with Metropolitan of Kiev Yevgeny (Bolkhovitinov) and to start a new life in the capital. They conducted an extensive correspondence, of which only individual letters to Innokenty (Borisov) and K. S. Serbinovich have been preserved. There are references to them in several letters. Their circle of communication included the historian of the Cossacks, educator and bibliophile Ivan Diomidovich Popko, who visited them more than once in St. Petersburg.
Results. Thanks to such fragmentary and scarce information, it was possible to recreate the brothers’ life paths to a certain extent.

Credit card fraud is still very much a problem in the United States, which has experienced increased opportunity in online shopping and digital payments. This paper aims at examining how the consumer data such as the demographic data, the purchasing behavior and the security measures they adopt can help improve fraud prevention measures. This study is based on survey data of 200 participants from US credit card users, supported by data on recent frauds. Other variables considered were age, income, number of online transactions, password creation and protection and two-factor authentication.
Quantitative data approaches such as descriptive and inferential statistics were used in this study whereby chi-square tests, t-tests and logistic regression were used in an attempt to determine the significant relationships that exist between consumer characteristics and fraud risk. A cross-tabulation of the variables provided a measure of association and showed that increased age, income level and the number of transactions made online were associated with increased vulnerability to fraud. Users with a low age and high income were classified as high-risk users because they make frequent transactions online and have larger amounts of digital data. Participants who provided proactive activities in security practice like changing passwords often and the use of two-factor authentication had a low risk of fraud, the need for consumers to be aware of risks.
Results indicate that it is possible to improve the security of credit cards in the US financial sector by implementing individual anti-fraud measures considering the behavioral and demographic characteristics of consumers. Consumer behavioral data enables the institutions to adopt dynamic approaches that involve real-time transaction notification and behavior-driven analytics to enhance the accuracy of fraud identification and reduce on false alarms. This paper also shows that behavior-inspired, evidence-based approaches hold the key to the improvement of credit card security and consumer confidence. Subsequent studies shall analyze how compliance influences the advanced data-based security solutions and such research can use the aged fraud typologies and trends to understand their possible changes over time.

Teluk Davao yang berada di wilayah yurisdiksi negara Filipina, secara geografis lokasinya berada dekat dengan pulau-pulau terluar di utara Indonesia. Dimana pulau-pulau terluar ini tidak memiliki stasiun pasang surut, sehingga Teluk Davao dianggap dapat merepresentasikan fenomena pasang surut pada pulau-pulau tersebut. Tujuan penelitian ini adalah untuk mengetahui tipe pasang surut pada lokasi penelitian serta mengolah konstanta harmonik pasang surut dengan metode Least Square menggunakan perangkat lunak t_tide yang berbasiskan bahasa pemrograman MatLab. Dari hasil penelitian ini dihasilkan konstanta harmonik sebanyak 32 konstanta yang menghasilkan nilai frekuensi, amplitudo, fase, dan SNR yang selanjutnya dijadikan bahan analisa. Dimana dari 32 konstanta yang didapatkan, 12 konstanta merupakan konstanta signifikan yang didominasi oleh konstanta diurnal. Nilai amplitudo tertinggi berada pada konstanta S2 dan M2 (semi-diurnal) sehingga menjelaskan mengapa tipe pasang surut yang didapatkan adalah tipe pasang surut harian ganda. Sedangkan 20 konstanta lainnya merupakan konstanta non-signifikan. Sementara itu hasil penghitungan bilangan Formzahl menunjukkan bahwa Teluk Davao juga bertipe pasang surut harian ganda dengan nilai sebesar 0,230493. Adapun tunggang pasang surut yang didapatkan dari hasil pengolahan dimana nilai maksimum adalah 2,27m dan nilai minimum adalah 0,12m.

Authors: Hammood Husam , H Ali Ameer , Jalil Aklo Nabil
Published: December 2024

Fast and accurate frequency estimation is essential in various engineering applications, including control systems, communications, and resonance sensing systems. This study investigates the effect of sample size on the interpolation algorithm of frequency estimation. In order to enhance the accuracy of frequency estimation and performance, we describe a novel method that provides a number of approaches for calculating and defending the sample size for of the window function designs, whereas, the correct choice of the type and the size of the window function makes it possible to reduce the error. Computer simulation using Matlab / Simulink environment is performed to investigate the proposed procedure's performance and feasibility. This study performs the comparison of the interpolation algorithm of frequency estimation strategies that can be applied to improve the accuracy of the frequency estimation. Simulation results shown that the proposed strategy with the Parzen and Flat-top gave remarkable change in the maximum error of frequency estimation. They perform better than the conventional windows at a sample size equal to 64 samples, where the maximum error of frequency estimation is 2.13e-2, and 2.15e-2 for Parzen and Flat-top windows, respectively. Moreover, the efficiency and performance of the Nuttall window also perform better than other windows, where the maximum error is 7.76×10-5 at a sample size equal to 8192. The analysis of simulation result showed that when using the proposed strategy to improve the accuracy of the frequency estimation, it is first essential to evaluate what is the maximum number of samples that can be obtained, how many spectral lines should be used in the calculations, and only after that choose a suitable window.
Continuous Fragmentation of Comet 157P/Tritton
Authors: Luu Jane , Jewitt David
Published: December 2024

We observed the split comet 157P/Tritton in 2022 October–November and 2024 January with the Nordic Optical Telescope. Our observations show that the splitting continued during the entire observing campaign. Fragmentation was associated with outbursts, consistent with the action of outgassing torques that spun up the nucleus and its fragments to the point of rotational instability. The outburst-fragmentation events can lead to a runaway process where the increasing spin rate, driven by outgassing torques, results in repeated mass loss until the sublimating body completely disintegrates.
The 10 pc Neighborhood of Habitable Zone Exoplanetary Systems: Threat Assessment from Stellar Encounters and Supernovae
Authors: Pyne Tisyagupta , Banyal Ravinder K. , Swastik C. , De Ayanabha
Published: December 2024

The habitability of a planet is influenced by both its parent star and the properties of its local stellar neighborhood. Potential threats to habitability from the local stellar environment mainly arise from two factors: cataclysmic events such as powerful stellar explosions and orbital perturbations induced by close stellar encounters. Among the 4500+ exoplanet-hosting stars, about 140+ are known to host planets in their habitable zones (HZs). In this study, we use Gaia Data Release 3 data to investigate the 10 pc stellar neighborhood of the 84 habitable zone systems (HZSs) closest to the Sun. We assess the possible risks that the local stellar environments of these HZSs pose to their habitability. In particular, we find that HD 165155 has a high stellar density around it, making it likely to experience at least one flyby encounter within a span of 5 Gyr. We also identified two high-mass stars (M ≥ 8 M
⊙) as potential progenitors of supernovae, which could threaten the long-term survivability of HZSs HD 48265 and TOI-1227. Further, to quantify the similarity between HZ stars and the Sun, as well as their respective 10 pc stellar environments, we employ various astrophysical parameters to define a solar similarity index and a neighborhood similarity index. Our analysis suggests that HD 40307 exhibits the closest resemblance to the solar system, while HD 165155 shows the least resemblance.
The Star-forming Main Sequence in JADES and CEERS at z > 1.4: Investigating the Burstiness of Star Formation

Published: December 2024

We have used public JWST/NIRSpec and JWST/NIRCam observations from the CEERS and JADES surveys in order to analyze the star-forming main sequence (SFMS) over the redshift range 1.4 ≤ z < 7. We calculate the star formation rates (SFRs) of the galaxy sample using three approaches: Balmer line luminosity, spectral energy distribution (SED) fitting, and UV luminosity. We find a larger degree of scatter about the SFMS using the Balmer-based SFRs compared to the UV-based SFRs. Because these SFR indicators are sensitive to star formation on different timescales, the difference in scatter may be evidence of bursty star formation histories in the early Universe. We additionally compare the Hα-to-UV luminosity ratio (L(Hα)/ν

Measuring the burstiness of star formation in the early Universe has multiple significant implications, such as deriving accurate physical parameters from SED fitting, explaining the evolution of the UV luminosity function, and providing constraints for subgrid models of feedback in simulations of galaxy formation and evolution.

Modern spectroscopic surveys can only target a small fraction of the vast amount of photometrically cataloged sources in wide-field surveys. Here, we report the development of a generative artificial intelligence (AI) method capable of predicting optical galaxy spectra from photometric broadband images alone. This method draws from the latest advances in diffusion models in combination with contrastive networks. We pass multiband galaxy images into the architecture to obtain optical spectra. From these, robust values for galaxy properties can be derived with any methods in the spectroscopic toolbox, such as standard population synthesis techniques and Lick indices. When trained and tested on 64 × 64 pixel images from the Sloan Digital Sky Survey, the global bimodality of star-forming and quiescent galaxies in photometric space is recovered, as well as a mass–metallicity relation of star-forming galaxies. The comparison between the observed and the artificially created spectra shows good agreement in overall metallicity, age, Dn4000, stellar velocity dispersion, and E(B − V) values. Photometric redshift estimates of our generative algorithm can compete with other current, specialized deep learning techniques. Moreover, this work is the first attempt in the literature to infer velocity dispersion from photometric images. Additionally, we can predict the presence of an active galactic nucleus up to an accuracy of 82%. With our method, scientifically interesting galaxy properties, normally requiring spectroscopic inputs, can be obtained in future data sets from large-scale photometric surveys alone. The spectra prediction via AI can further assist in creating realistic mock catalogs.

Infrared (IR) spectral features of interstellar and solar system ices have been attributed to solid organic and inorganic compounds for over 50 yr, but in many cases the laboratory IR data needed to fully quantify such work have never been published, forcing researchers to rely on assumptions about gas- or liquid-phase measurements to interpret data for ices. Here, we report the first mid-IR intensity measurements for isocyanic acid (HNCO) ices that are free of such assumptions, providing new results for use by both observational and laboratory astrochemists. We also report similar new IR data for both formaldehyde (H2CO) and formic acid (HCOOH), which have been discussed in the astrochemical literature for decades, but again without adequate laboratory data to help quantify observational results. Densities and refractive indices of HNCO, H2CO, and HCOOH as amorphous ices also are reported. Two applications of the new H2CO work are presented, the first vapor-pressure measurements of solid H2CO, along with an enthalpy of sublimation, at 100 to 109 K and a set of IR intensities of H2CO in H2O + H2CO ices. Band strengths, absorption coefficients, and optical constants are calculated for all three compounds. Extensive comparisons are made to older results, which are not recommended for future use.

We present the Atacama Large Millimeter/submillimeter Array Band 7 observations of the CO (J = 3−2) line emission of the protostellar system HH 212 at ∼24 au spatial resolution and compare them to those of the SiO (J = 8−7) and SO (J = 8−7) line emission reported in the literature. We find that the CO line traces four distinct regions: (1) an outer outflow shell, (2) a rotating wind region between the SiO and CO shells, (3) the shocked and wide-angle inner X-wind inside a SiO shell, and (4) the jet. The origin of the CO outer outflow shell could be associated with the entrained material of the envelope, or an extended disk wind. The rotating wind, which is shocked, is launched from a radius of 9–15 au, slightly exterior to that of the previously detected SO shell, which marks the boundary where the wide-angle X-wind is interacting with and shocking the disk wind. Additionally, the SO is found to be mixed with the CO emission within the thick and extended rotating wind region. The large-scale CO-shocked wind coexists with the SO emission near the upper portion of the inner shocked region converged on top of the inner SiO knots. The CO jet is traced by a chain of knots with roughly equal intervals, exhibiting quasiperiodicity, as reported in other jets in the literature.
Mergers, Radio Jets, and Quenching Star Formation in Massive Galaxies: Quantifying Their Synchronized Cosmic Evolution and Assessing the Energetics

The existence of a population of massive quiescent galaxies with little to no star formation poses a challenge to our understanding of galaxy evolution. The physical process that quenched the star formation in these galaxies is debated, but the most popular possibility is that feedback from supermassive black holes lifts or heats the gas that would otherwise be used to form stars. In this paper, we evaluate this idea in two ways. First, we compare the cumulative growth in the cosmic inventory of the total stellar mass in quiescent galaxies to the corresponding growth in the amount of kinetic energy carried by radio jets. We find that these two inventories are remarkably well-synchronized, with about 50% of the total amounts being created in the epoch from z ≈ 1 to 2. We also show that these agree extremely well with the corresponding growth in the cumulative number of major mergers that result in massive (>1011
M
ʘ) galaxies. We therefore argue that major mergers trigger the radio jets and also transform the galaxies from disks to spheroids. Second, we evaluate the total amount of kinetic energy delivered by jets and compare it to the baryonic binding energy of the galaxies. We find the jet kinetic energy is more than sufficient to quench star formation, and the quenching process should be more effective in more massive galaxies. We show that these results are quantitatively consistent with recent measurements of the Sunyaev–Zel’dovich effect seen in massive galaxies at z ≈ 1.
Detailed Calculations of the Efficiency of Planetesimal Accretion in the Core-accretion Model. III. The Contribution of Planetesimals beyond Saturn

Continuing our initiative on advancing the calculations of planetesimal accretion in the core-accretion model, we present here the results of our recent study of the contributions of planetesimals around and beyond the orbit of Saturn. In our first two papers, where our focus was on the effects of the Sun and Saturn, the initial distribution of planetesimals was limited to the regions around the accretion zone of a growing Jupiter. In this paper, we expanded that distribution to regions beyond the accretion zone of Saturn. We integrated the orbits of a large ensemble of planetesimals and studied the rate of their capture by the growing proto-Jupiter. In order to be consistent with our previous studies, we did not consider the effect of the nebular gas. Results demonstrated that the exterior planetesimals, especially those beyond 8 au, have only slight contributions to the growth and metallicity of the growing Jupiter. The final mass and composition of this planet is mainly due to the planetesimals inside and around its accretion zone. Our study shows that although the rate of capture varies slightly by the size and composition of planetesimals, in general, the final results are independent of the size and material of these bodies. Results also pointed to a new finding: the rate of accretion follows the same trend as that of the evolution of Jupiter’s envelope, with the largest accretion occurring during the envelope’s collapse. We present details of our analysis and discuss the implications of its results.

We present spectroscopic and photometric observations of Bernhard-2, which was previously identified as a candidate system that hosts a misaligned circumbinary disk. Our spectroscopic measurements confirm that Bernhard-2 indeed contains an eccentric (e = 0.69 ± 0.08) binary and thus that the periodic variability in the photometric light curve is best explained by the occultation by the misaligned circumbinary disk. By modeling the spectral energy distributions at different phases, we infer the masses of the two binary components to be ∼1.1 M
⊙ and ∼0.9 M
⊙, respectively. The system age is determined to be ≲20 Myr by combining the stellar isochrone model with lithium abundance. Our new photometric observations show clear deviations from the model prediction based on the archival data, suggesting ongoing precession of the circumbinary disk. The Hα line of Bernhard-2 also shows an inverse P-Cygni profile at epochs close to the pericenter passage, which could be attributed to the pulsed accretion around the pericenter. Bernhard-2 therefore closely resembles the well-studied KH 15D system. Further detailed observations and studies of such rare systems can provide useful information about disk physics and evolution.
