Abstract
The magnetic dipole moment μ of an accretion-powered pulsar in magnetocentrifugal equilibrium cannot be inferred uniquely from time-averaged pulse period and aperiodic X-ray flux data, because the radiative efficiency η
0 of the accretion is unknown, as are the mass, radius, and distance of the star. The degeneracy associated with the radiative efficiency is circumvented if fluctuations of the pulse period and aperiodic X-ray flux are tracked with a Kalman filter, whereupon μ can be measured uniquely up to the uncertainties in the mass, radius, and distance. Here, the Kalman filter analysis is demonstrated successfully in practice for the first time on Rossi X-ray Timing Explorer observations of the X-ray transient SXP 18.3 in the Small Magellanic Cloud (SMC), which is monitored regularly.

The success of the demonstration confirms that the Kalman filter analysis can be applied in the future to study the magnetic moments and disk–magnetosphere physics of accretion-powered pulsar populations in the SMC and elsewhere.

Abstract
Galaxies play a key role in our endeavor to understand how structure formation proceeds in the Universe. For any precision study of cosmology or galaxy formation, there is a strong demand for huge sets of realistic mock galaxy catalogs, spanning cosmologically significant volumes. For such a daunting task, methods that can produce a direct mapping between dark matter halos from dark matter-only simulations and galaxies are strongly preferred, as producing mocks from full-fledged hydrodynamical simulations or semi-analytical models is too expensive. Here, we present a graph-neural-network-based model that is able to accurately predict key properties of galaxies such as stellar mass, g − r color, star formation rate, gas mass, stellar metallicity, and gas metallicity, purely from dark matter properties extracted from halos along the full assembly history of the galaxies. Tests based on the TNG300 simulation of the IllustrisTNG project show that our model can recover the baryonic properties of galaxies to high accuracy, over a wide redshift range (z = 0–5), for all galaxies with stellar masses more massive than 109
M
⊙ and their progenitors, with strong improvements over the state-of-the-art methods. We further show that our method makes substantial strides toward providing an understanding of the implications of the IllustrisTNG galaxy formation model.

Abstract
Recent Atacama Large Millimeter/submillimeter Array (ALMA) observations have revealed an increasing number of compact protostellar disks with radii of less than a few tens of astronomical units and that young Class 0/I objects have an intrinsic size diversity. To deepen our understanding of the origin of such tiny disks, we have performed highest-resolution configuration observations with ALMA at a beam size of ∼0.″03 (4 au) on the very low-luminosity Class 0 protostar embedded in the Taurus dense core MC 27/L1521F. The 1.3 mm continuum measurement successfully resolved a tiny, faint (∼1 mJy) disk with a major axis length of ∼10 au, one of the smallest examples in the ALMA protostellar studies. In addition, we detected spike-like components in the northeastern direction at the disk edge. Gravitational instability or other fragmentation mechanisms cannot explain the structures, given the central stellar mass of ∼0.2 M
⊙ and the disk mass of ≳10−4
M
⊙. Instead, we propose that these small spike structures were formed by a recent dynamic magnetic flux transport event due to interchange instability that would be favorable to occur if the parental core has a strong magnetic field. The presence of complex arc-like structures on a larger (∼2000 au) scale in the same direction as the spike structures suggests that the event was not single. Such episodic, dynamical events may play an important role in maintaining the compact nature of the protostellar disk in the complex gas envelope during the main accretion phase.

Abstract
Lithium is a fragile but crucial chemical element in the Universe, and exhibits interesting and complex behaviors. Thanks to the mass of spectroscopic data from the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) medium-resolution survey (MRS), we can investigate the lithium abundances in a large and diverse sample of stars, which could bring vital help in studying the origin and evolution of lithium. In this work, we use the Li i 6707.8 Å line to derive the lithium abundance through a template-matching method. A catalog of precise lithium abundance is presented for 795,384 spectra corresponding to 455,752 stars from the LAMOST MRS Data Release 9. Comparing our results with those of external high-resolution references, we find good consistency with a typical deviation of σ
A(Li) ∼ 0.2 dex. We also analyze the internal errors using stars that have multiple LAMOST MRS observations, which will reach as low as 0.1 dex when the signal-to-noise ratio of the spectra is >20. Besides, our result indicates that a small fraction of giant stars still exhibit a surprisingly high lithium content, and 967 stars are identified as Li-rich giants with A(Li) > 1.5 dex, accounting for ∼2.6% of our samples. If one takes into account the fact that nearly all stars deplete lithium during the main sequence, then the fraction of Li-rich stars may far exceed 2.6%. This new catalog covers a wide range of stellar evolutionary stages from pre-main sequence to giants, and will provide help to the further study of the chemical evolution of lithium.
Challenges for the viticultural landscape – The case of Vipava Hills in Slovenia
Authors: Topole Maja , Šmid Hribar Mateja , Kokalj Žiga 
Published: April 2024

The article deals with the Vipava Hills, one of the oldest and still promising Slovenian wine-growing regions. Despite the favourable natural conditions, especially for organic viticulture, a comparison of land use in the last two decades shows the abandonment and overgrowth of vineyards in the higher, so-called vineyard sites and, on the other hand, their relocation to the bottom of the Vipava Valley, where grape production is intensified. The article discusses the obstacles leading to the unfavourable development trends in the landscape and demography, and proposes measures that could, on the one hand, prevent further abandonment of agricultural land, especially vineyard land, population out-migration and biodiversity decline and, on the other hand, make better use of the advantages of the ideal combination of climatic, lithological and pedological features, the mosaic-like structure of the landscape, the high degree of naturalness, the extensive protected areas of Natura 2000 and, last but not least, the rich cultural heritage of the region.
Izzivi vinogradniške pokrajine – primer Vipavskega gričevja v Sloveniji
Prispevek obravnava Vipavsko gričevje, eno najstarejših in tudi danes obetavnih slovenskih vinogradniških pokrajin. Kljub ugodnim naravnim razmeram, posebej za ekološko vinogradništvo, primerjava rabe zemljišč v zadnjih dveh desetletjih kaže opuščanje in zaraščanje vinogradov v višjih, t. i. vinogradniških legah, po drugi strani pa njihovo selitev proti dnu Vipavske doline, kjer prihaja do intenzifikacije pridelave grozdja. Članek govori o ovirah, ki povzročajo neugodne razvojne trende v pokrajini in demografiji ter predlaga ukrepe, s katerimi bi lahko na eni strani preprečili nadaljnje opuščanje kmetijskih, posebej vinogradniških zemljišč, izseljevanje prebivalcev in upadanje biodiverzitete, po drugi pa bolje izkoristili prednosti idealne kombinacije podnebnih, kamninskih in pedoloških lastnosti, mozaične strukture pokrajine, visoke stopnje naravnosti, obsežnih zavarovanih območij Nature 2000 in nenazadnje bogate kulturne dediščine regije.

Authors: Drouet Quentin Benoît Guillaume , Koderman Miha 
Published: April 2024

The article examines selected methodological challenges in research on second homes, putting into perspective the transnational, national and local levels, with the cases of the Alpine region, Slovenia and the Municipality of Kranjska Gora. The heterogeneity of residential patterns, the dynamic of housing development and the disparities in the terminology limit comparisons at international level. National data on second homes in Slovenia are put in focus of a critical evaluation, as they surprisingly show a decreasing trend in the last two decades, and were recently abolished as a statistical category. The article also discusses the differences of official databases of second homes in the Municipality of Kranjska Gora and addresses potential suggestions for improvement of their quality.
Metodološki izzivi pri preučevanju sekundarnih počitniških bivališč: izkušnje iz alpske regije, Slovenije in Občine Kranjska Gora
V članku smo preučili izbrane metodološke izzive pri preučevanju sekundarnih počitniških bivališč, pri čemer smo se na primerih alpskega prostora, Slovenije in Občine Kranjska Gora osredinili na problematiko z mednarodne, državne in lokalne ravni. Raznoterost bivalnih vzorcev, dinamika stanovanjskega razvoja in razlike v terminologiji omejujejo natančne primerjave pojava na mednarodni ravni. Kritično so ovrednoteni državni podatki o sekundarnih počitniških bivališčih v Sloveniji, saj v zadnjih dveh desetletjih presenetljivo izkazujejo trend zmanjševanja, pred kratkim pa so bili ukinjeni kot statistična kategorija. Članek obravnava tudi razlike med uradnima zbirkama podatkov o počitniških bivališčih na območju Občine Kranjska Gora in razpravlja o možnih predlogih za izboljšanje njihove kakovosti.

Authors: Sergeyeva Aigul , Omirzakova Miroslava , Saparov Kuat 
Published: April 2024

This article deals with the sustainable development of rural tourism based on geotourism. Geotourism makes it possible to preserve geological and geomorphological features and use them effectively for tourism. In the Aktobe Oblast administrative region, these features are effectively used for the development of rural tourism. Geological and geomorphological features in the region are not protected by the state, so it is important for the future development of geotourism and rural tourism to protect them. In order to effectively evaluate the development of rural tourism and geotourism, the Delphi method was applied and a SWOT analysis was conducted. With the SWOT analysis, the strengths and weaknesses of geotourism and rural tourism of the Aktobe Oblast are assessed.

Authors: He Ni , Liu Hanxiu , Liu Jing , Wang Xiqiang , Wang Junkui , Xu Hengwei , Liu Zhongwei 
Published: April 2024

Abstract
Mood disorders, encompassing major depressive disorder and bipolar disorder, present complex etiologies involving neuroanatomical, neurotransmitter, and inflammatory mechanisms. Recent research explores the role of platelets, traditionally associated with hemostasis, in the pathophysiology of mood disorders. We examine neuroanatomical insights, neurotransmitter dysregulation, and the link between inflammation and mood disorders, emphasizing the complex nature of mood disturbances. Emerging evidence of altered platelet function in mood disorders and the therapeutic potential of antiplatelet agents and serotonin reuptake inhibitors are discussed. While personalized medicine holds promise, further research is needed to fully comprehend this evolving field. This review offers comprehensive insights into mood disorder diagnosis, intervention, and pathophysiology. In this review, a comprehensive literature search was conducted using databases such as PubMed, Scopus, and Web of Science. The search focused on articles published from 2000 to 2023, using keywords like “platelet function,” “mood disorders,” and “neurotransmitter dysregulation.” We included studies that specifically investigated the role of platelets in mood disorders, encompassing various study designs and population demographics.

Authors: Aljiffry Murad M. , Radwi Mansoor R. , Binjahlan Albandari A. , Farsi Sara H. , Farsi Ali H. 
Published: April 2024

CONTEXT:
Postoperative Portomesenteric venous thrombosis (PMVT), is a rare but significant condition that occurs in colorectal surgery patients. PMVT involves thrombus formation in veins such as the portal, superior mesenteric, inferior mesenteric, or splenic vein, often following colon and rectum surgical resection. Recognized risk factors include cancer and inflammatory bowel disease.

AIMS:
The research aimed to evaluate the prevalence, associated risk factors, and treatment methods for PMVT in a large academic tertiary care hospital.

SETTINGS AND DESIGN:
Retrospective review

METHODS:
A retrospective review of 750 colorectal surgeries was conducted, examining patient medical histories, operative details, perioperative medications, and postoperative complications.

STATISTICAL ANALYSIS USED:
Categorical variables were presented as frequencies and percentages, whereas continuous variables were presented as a mean +/- Standard deviation. Comparative analysis used odds ratios to understand the association between categorical risk factors and PMVT, and independent samples t-tests for continuous variables

RESULTS:
PMVT was identified in 0.8% of the 621 patients meeting the inclusion criteria, all of whom had underlying cancer. These patients were successfully treated with anticoagulants, without the need for surgery or resulting in any mortality at 45 days postoperatively. No significant variables associated with PMVT were identified in this cohort.

CONCLUSIONS:
PMVT after colorectal surgery, while rare, is predominantly seen in patients with cancer. The outcomes in these cases were favorable with medical therapy alone. Larger, long-term studies are recommended to further investigate risk factors and effective management strategies for PMVT.
Prevalence and risk factors of diabetes mellitus among elderly patients in the Lugu community
Authors: Zhao Li-Zhen , Li Wei-Min , Ma Ying 
Published: April 2024

BACKGROUND
Age is a significant risk factor of diabetes mellitus (DM). With the develop of population aging, the incidence of DM remains increasing. Understanding the epidemiology of DM among elderly individuals in a certain area contributes to the DM interventions for the local elderly individuals with high risk of DM.
AIM
To explore the prevalence of DM among elderly individuals in the Lugu community and analyze the related risk factors to provide a valid scientific basis for the health management of elderly individuals.
METHODS
A total of 4816 elderly people who came to the community for physical examination were retrospectively analyzed. The prevalence of DM among the elderly was calculated. The individuals were divided into a DM group and a non-DM group according to the diagnosis of DM to compare the differences in diastolic blood pressure (DBP) and systolic blood pressure (SBP), fasting blood glucose, body mass index (BMI), waist-to-hip ratio (WHR) and incidence of hypertension (HT), coronary heart disease (CHD), and chronic kidney disease (CKD).
RESULTS
DM was diagnosed in 32.70% of the 4816 elderly people. The BMI of the DM group (25.16 ± 3.35) was greater than that of the non-DM group (24.61 ± 3.78). The WHR was 0.90 ± 0.04 in the non-DM group and 0.90 ± 0.03 in the DM group, with no significant difference. The left SBP and SBP in the DM group were 137.9 mmHg ± 11.92 mmHg and 69.95 mmHg ± 7.75 mmHg, respectively, while they were 126.6 mmHg ± 12.44 mmHg and 71.15 mmHg ± 12.55 mmHg, respectively, in the non-DM group. These findings indicate higher SBP and lower DBP in DM patients than in those without DM. In the DM group, 1274 patients were diagnosed with HT, accounting for 80.89%. Among the 3241 non-DM patients, 1743 (53.78%) were hypertensive and 1498 (46.22%) were nonhypertensive. The DM group had more cases of HT than did the non-DM group. There were more patients with CHD or CKD in the DM group than in the non-DM group. There were more patients who drank alcohol more frequently (≥ 3 times) in the DM group than in the non-DM group.
CONCLUSION
Older adults in the Lugu community are at a greater risk of DM. In elderly individuals, DM is closely related to high BMI and HT, CHD, and CKD. Physical examinations should be actively carried out for elderly people to determine their BMI, SBP, DBP, and other signs, and sufficient attention should be given to abnormalities in the above signs before further diagnosis.
Examining the association between delay discounting, delay aversion and physical activity in Chinese adults with type-2 diabetes mellitus
Authors: An Yong-Dong , Ma Guo-Xia , Cai Xing-Kui , Yang Ying , Wang Fang , Zhang Zhan-Lin 
Published: April 2024

BACKGROUND
The role of physical activity in diabetes is critical, influencing this disease's development, man-agement, and overall outcomes. In China, 22.3% of adults do not meet the minimum level of physical activity recommended by the World Health Organization. Therefore, it is imperative to identify the factors that contributing to lack of physical activity must be identified.
AIM
To investigate the relationship among delay discounting, delay aversion, glycated hemoglobin (HbA1c), and various levels of physical activity in Chinese adults diagnosed with type 2 diabetes mellitus (T2DM).
METHODS
In 2023, 400 adults with T2DM were recruited from the People's Hospital of Linxia Hui Autonomous Prefecture of Gansu Province. A face-to-face questionnaire was used to gather demographic data and details on physical activity, delay discounting, and delay aversion. In addition, HbA1c levels were measured in all 400 participants. The primary independent variables considered were delay discounting and delay aversion. The outcome variables included HbA1c levels and different intensity levels of physical activity, including walking, moderate physical activity, and vigorous physical activity. Multiple linear regression models were utilized to assess the relationship between delay discounting, delay aversion, and HbA1c levels, along with the intensity of different physical activity measured in met-hours per week.
RESULTS
After controlling for the sample characteristics, delay discounting was negatively associated with moderate physical activity (β = -2.386, 95%CI: -4.370 to -0.401). Meanwhile, delay aversion was negatively associated with the level of moderate physical activity (β = -3.527, 95% CI = -5.578 to -1.476) in the multiple linear regression model, with statistically significant differences.
CONCLUSION
Elevated delay discounting and increased delay aversion correlated with reduced levels of moderate physical activity. Result suggests that delay discounting and aversion may influence engagement in moderate physical activity. This study recommends that health administration and government consider delay discounting and delay aversion when formulating behavioral intervention strategies and treatment guidelines involving physical activity for patients with T2DM, which may increase participation in physical activity. This study contributes a novel perspective to the research on physical activity in adults with T2DM by examining the significance of future health considerations and the role of emotional responses to delays.
