Authors: Asetskaya I. L. , Zyryanov S. K. , Samsonova K. I. , Butranova O. I. , Terekhina E. N. , Polivanov V. A.
Published: October 2024

INTRODUCTION. Newly identified risks associated with the use of fluoroquinolones and the spread of antimicrobial resistance make the identification and analysis of medication errors (MEs) in prescribing fluoroquinolones especially important for providing rational antibiotic therapy. Fluoroquinolones that are most commonly used in real-world clinical settings include levofloxacin.

AIM. This study aimed to examine the pattern of MEs associated with fluoroquinolones, exemplified by levofloxacin, through an analysis of spontaneous reports (SRs) submitted to the Russian pharmacovigilance database.

MATERIALS AND METHODS. The authors retrospectively analysed the SRs of adverse drug reactions (ADRs) submitted to the Russian pharmacovigilance database between 1 April 2019 and 28 February 2023. According to the selected inclusion criteria, the study focused on the SRs that specified levofloxacin as a suspect medicinal product and described ADRs that took place in the Russian Federation. ME identification used summaries of product characteristics for levofloxacin approved in Russia, official clinical guidelines, and the antimicrobial stewardship guidelines Strategy for the Control of Antimicrobial Therapy (SCAT).

RESULTS. The analysis included 950 SRs. MEs were identified in 307 (32.3%) of these SRs, and the total number of MEs was 332. MEs associated with the selection of the medicinal product included prescribing levofloxacin to patients without an indication for antibacterial therapy (38.9%, n=129, with 76.0% of cases being viral infections), incorrect selection of levofloxacin as a first-line antibacterial agent (18.1%, n=60), and irrational and excessive prescribing of levofloxacin in combination with other antibacterial agents (15.4%, n=51). Less frequently identified MEs were related to inappropriate dosing (13.0%, n=43), levofloxacin use in patients with contraindications (8.7%, n=29), and incorrect selection of the route of administration (3.9%, n=13) and the dosage form (2.1%, n=7).

CONCLUSIONS. According to the results of this study, the practice of prescribing antibacterial agents for viral infections persists despite strong evidence of ineffectiveness in such cases. Antibacterial agents can be used effectively and safely only if prescribed for approved indications, administered at recommended doses, and delivered via specified routes of administration. The overuse of antibiotics may have negative sequelae not only for the health of an individual patient but for the health of the general population because of the increased risk of antimicrobial resistance. Therefore, there is a need to develop measures to limit the excessive use of antibiotics.

Indonesia is a country that pays attention to Eastern tradition, namely in politeness value either in attitude or socialization. Politeness in fashion considers the importance of the value of politeness in clothing. The politeness limitation in fashion in Indonesia was from the navel to ankles by exploring historically to find out the fashion change, especially in traditional clothing in Indonesia in some periods. This research aimed to trace the chronology of fashion change in traditional women in Indonesia from 1900 until 2000 and to study the fashion change from 1900 until 2000. The research method was historical, with data in figure samples obtained from 1900 until 2000. This research resulted in the chronology of the transformation of fashion change in traditional women's underwear from 1900 until 2000. This research found that fashion shifted from Colonialism to the Reformation. The conventional cloth changed from the initial usage, namely kemben, to bustier. Kemben usage in 1860, camisole usage in 1925, and the old order in 1954 is bustier. The length level of fashion design experienced a decrease. In the colonial period, traditional undergarments covered the breast. Still, in the reformation era, some only lasted until the peak of the breast, initially only from the navel until the ankle, then changed from the breast to the ankle. Technological advances have impacted the freedom to access information included in fashion.

Stepwise double-sided friction stir welding: an alternative for root defect mitigation in aluminium plates with lower gauge numbers
Authors: Ojo Olatunji Oladimeji , Oboro Ozioma Alaba
Published: October 2024

Penetration-induced fractional unbonded defects and flow-induced root flaws are part of the discontinuities of the conventional friction stir welded (FSW’ed) aluminium alloys with limited impact assessment/clarification in literature. The novelty of this study lies in the attempt to eliminate penetration-aided root defect via a stepwise double-sided welding process as well as identify its impact on loadbearing. As a result, the stepwise double-sided FSW welding of a thick aluminium plate (6 mm) was carried out while the microstructure, strength, and fracture modes of the ensuing welds were compared with the conventional (single-sided) friction stir welded counterparts. The stepwise double-sided FSW-welded joint demonstrated better tensile strength relative to the single-sided FSW-welded counterparts owing to its material flow consolidation (two-side deformation) and elimination of penetration-induced fractional unbonded region/root defect. The welding processes do not have a noteworthy influence on the fracture location of the welds as failure ensued via the stir zones of the respective welds. Transient breaking/brittle appearance, and ductile fracture modes were noticed in the single-sided and stepwise double-sided FSW-welded samples respectively. The stepwise double-sided FSW process is recommended as a better choice for thick workpieces relative to conventional FSW to improve the weld’s loadbearing resistance.
Development of geometry-driven quantitative prediction for shrinkage porosity in T-junction of steel sand castings
Authors: Mazloum Kamar , Sata Amit
Published: October 2024

Shrinkage porosity poses a significant challenge in metal casting processes, impacting both productivity and energy efficiency, especially when dealing with components that are not accepted or reprocessed. Addressing this issue requires proactive measures, and predictive techniques play a crucial role in minimizing its occurrence. Among these methods, the Criterion Function stands out as a valuable empirical model extensively explored in the literature. By intricately linking solidification processes to the development of shrinkage porosity, the Criterion Function leverages key process parameters, including thermal gradient, molten metal velocity during solidification, and cooling rate, to offer predictive insights into the location and presence of porosity. However, a criterion function is needed that also considers the effect of geometric variations as well as the size of the defect (shrinkage porosity). In this study, a casting with three T-joints was taken as a benchmark shape to develop a geometry-based quantitative prediction model for plain carbon steel castings. Real experimental results were combined with solidification simulation results to produce reliable data, which were then used to extrapolate the results. The developed quantitative prediction model, which includes the effect of geometric changes, has been validated and proven effective in predicting shrinkage porosity.

The genus Phellodon (Thelephorales, Basidiomycota) in Europe: Four new species, one new combination, four new typifications and a first European record
Authors: Svantesson S. , Larsson E. , Larsson K.-H. , Parfitt D. , Suz L.M. , Ainsworth A.M.
Published: October 2024

Phellodon is a globally distributed genus of stipitate hydnoid fungi recognised by a white spore print and an ectomycorrhizal life strategy. In Europe, many Phellodon species have declining populations and are used as indicators of forests with high conservation values. However, their use in this context and the correct assessment of their extinction risk, according to IUCN guidelines, are currently hampered by inconsistent name usage and unclear species delimitations, primarily within the species complexes of P. melaleucus, P. niger and P. tomentosus. We analysed 286 ITS sequences of Phellodon, of which 51 were also analysed in conjunction with the corresponding LSU regions. This work included 102 newly sequenced collections, primarily sourced from Sweden and the UK. Our phylogenetic results show that four species are new to science and hence we formally describe P. castaneoleucus within the P. melaleucus morphological complex, P. aquiloniniger and P. frondosoniger within the P. niger complex and P. dititomentosus as a sister species to P. tomentosus. The combination P. melilotinus is made to accommodate an additional, previously described, species that belongs in the P. niger complex. We designate lectotypes and epitypes for P. melaleucus, P. niger and P. tomentosus as well as an epitype for P. melilotinus. Phellodon ellisianus is recorded as new to Europe and the ecological amplitude of P. secretus and P. violaceus is revealed to be wider than previously believed. We provide a key to all 13 species currently known in Europe and assign them to three habitat-based assemblages based on data from the Nordic countries and the UK. We hope this will facilitate the assessment of such habitats for legal protection and other conservation-related actions.

Published: October 2024

Today a lot of agricultural sectors are using IoT technology for smart farming, or minimally invasive human involvement, in order to improve production, efficiency, and worldwide marketing, among other aspects of farming. Our economy's overall functioning depends heavily on agriculture, which is a sector that is just as conducive to automation application as industry. In today's society, severe and persistent illnesses are primarily treated using herbal medications. Similar to conventional treatment, herbal therapies have been used for a long time and have very few negative effects. It will therefore be more advantageous to cultivate the herbal plants in the best and most straightforward approach. This project suggests methods for growing herbal plants indoors as efficiently as possible using LED lighting. The plants are constantly observed by means of an automated system made up of sensors for temperature, humidity, and soil moisture. For this experiment, four herbs such as mint, holi basil, country borage, and keezhanelli are used. These herbs are cultivated in both natural light and under LED lighting, and they are constantly being observed by sensors that measure temperature, moisture, and humidity. AgriBot captured daily photos of the plant in order to track its growth and compare it to plants growing in the sun. Additionally, a convolutional neural network is used to examine the plants' growth rate, and the results are compared to that of herbaceous plants that are produced naturally. At 30◦C, 860 level of wetness, and 74 level of humidity on the seventh day, the plant cultivated under LEDs thrived nicely. When compared to other herbs, mint and country borage have grown significantly. Thus, precision agriculture combined with indoor farming produces a large output in a short amount of time.
LLM Survey Analysis Using Random Forest
Authors: Singla Priyanka
Published: October 2024

This project investigates the application of a Random Forest Classifier for analyzing metadata from survey papers on large language models (LLMs), a rapidly growing area within AI. The goal is to assist new researchers by providing insights into the trends and patterns in LLM survey publications. Through a structured workflow—comprising data loading, exploration, manipulation, and visualization—key attributes such as release dates, categories, and taxonomies were analyzed. Techniques like TF-IDF vectorization, one-hot encoding, and feature scaling were employed to construct a robust feature matrix. Hyperparameter tuning using grid search optimized the classifier’s performance. Although the model achieved perfect training accuracy, a lower test accuracy (0.39) indicated overfitting, likely caused by dataset imbalance. With a best cross-validation score of 0.26, future improvements will focus on addressing data imbalance, enhancing feature engineering, and exploring alternative models to boost performance.

A recent meta-analysis published in this journal included 27 studies that experimentally manipulated social media use and investigated their impact on mental health outcomes (Ferguson, 2024). The author concluded that social media effects were statistically no different from zero. However, this meta-analysis did not investigate potential moderating effects of length of social media reduction or abstinence interventions. We conducted a re-analysis to investigate the impact of social media reduction/abstinence intervention length on mental health outcomes. We used the information available on the Open Science Framework platform related to the original meta-analysis and excluded seven studies because they were not reduction/abstinence interventions. We categorized studies into those with intervention lengths of less than 1 week versus 1 week or longer and also tested for curvilinear relationships between intervention length (weeks and days as continuous variables) and outcomes by including quadratic terms. Stratified analyses indicated that interventions of less than 1 week resulted in significantly worse mental health outcomes (d = −0.175), while interventions of 1 week or longer resulted in significant improvements (d = 0.156). Analyses of intervention length as continuous moderator included 19 studies and showed significant quadratic effects for number of weeks (p = .013) and number of days (p = .018). These findings suggest that social media use reduction/abstinence interventions should have a minimum length of 1 week or longer to confer mental health benefits. An ideal intervention length may be around 3 weeks, but future research is needed to confirm this.

Introduction:The relationship between cognitive tasks and physical performance has garnered significant attention, with evidence suggesting that cognitive effort before exercise may impair physical performance. However, recent findings challenge the robustness of this effect, necessitating a reassessment of the mechanisms linking cognitive load to physical performance. This study introduces a novel approach to address methodological limitations, emphasizing individualized cognitive task difficulty and duration. Using techniques such as Temporal Experience Tracing (TET) and psychophysiological monitoring, we explore the dynamics between cognitive effort, subjective states, and physical performance.Methods:In a pre-registered, randomized, within-participant design experiment, 21 recreational athletes completed a running time to exhaustion test at 90% of their maximal aerobic speed after performing a cognitive task until failure or watching a self-selected documentary. Pupillometry and six subjective dimensions were measured with the TET during task performance.Results:We found that 1) subjective changes during effortful tasks are not limited to a single experience, such as mental fatigue or boredom, but can be grouped into distinct patterns; 2) the individualized and demanding cognitive task, completed before exercise did not impair subsequent physical performance; 3) pupil size reliably reflected cognitive load and is partially related to changes in subjective states, while fixation on the stimulus decreased over time, especially during high-demand periods.Conclusion:These results do not support the effect of performing a highly demanding cognitive task on subsequent strenuous physical performance. Instead, they reveal the richness of the subjective experience linked to cognitive performance that goes beyond mere mental fatigue. Overall, we show a novel way to understand the interplay between cognitive and physical performance.
Infinite Heroes and Quests of Skyrim: Investigating the Role of Norse Mythology in the Longevity of Bethesda Game Studios’ Video Game 'The Elder Scrolls V'
Authors: Maiello Giuseppe , Giungato Luigi
Published: October 2024

This study examines the connections between narratives in video game genres, particularly action RPGs, and the processes of appropriation and circulation among communities, analyzing in deept. the interaction dynamics between the lore narratives of "The Elder Scrolls V: Skyrim" and information shared inside Reddit forums. The study suggests that the Norse mythology in the video game Skyrim does not directly correlate with contemporary social conflicts. Instead, it suggests that socially relevant themes and ideologies may be attracted to different channels, such as less specific spaces. This aligns with the echo chamber model, where different themes correspond to different communicative and performative spaces. The Norse mythology serves as an open narrative infrastructure for the game's designers and players, supporting the construction of the possible world of the lore. However, the study does not show direct contamination effects on communities, suggesting that the lore may indirectly produce ideology on socially relevant issues.

Trivalent lanthanide (Ln3+; Ln = Tm, Ho, Cr)-doped Y3AlGa4O12nano-garnet phosphor powders with varying Cr3+ ion concentration (0.5, 1.0, 2.0 and 3.0 mol%) were prepared using sol-gel synthesis. The prepared powders were characterized by X-ray powder diffraction (XRD), Raman spectroscopic and photoluminescence spectroscopic techniques. Phase purity, structure and crystallite size have been estimated from the XRD results. Raman spectra showed the vibrational analysis of the prepared powders. Excitation spectrum showed a broad band at 354 nm when monitored at 712 nm. Under 360 nm excitation, emission spectrashowed a broad band with characteristic peaks of Tm3+, Ho3+ and Cr3+ ions. The intensity of peaks and full width at half maximum were increased up to 2.0 mol% Cr3+ ion and then decreased. All the decay curves exhibited non-exponential nature with an average lifetime of 0.302 ms. The decay curves were found to be insensitive to the Cr3+ ion concentration. The CIE colour co-ordinates were located in the orange-red region of the CIE diagram with correlated colour temperature 2261 K. The results showed that the present phosphors were suitable for the solidstate light emitting diode applications.

Published: October 2024

The presence of arterial stenosis significantly disrupts normal flow, posing heightened risks and exerting a greater impact on the cardiovascular system compared to other geometric abnormalities. The investigation of flow parameters in an artery with mild stenosis necessitates analyzing the varying viscosity of blood from the central core line to the vessel wall. This study employs the Navier-Stokes equation in cylindrical polar form to analyze fluid dynamics in axisymmetric directions, accounting for the effective viscosity of blood at radial distances (Einstein coefficient of blood viscosity).By solving this equation with appropriate boundary conditions, analytical expressions for the velocity profile, volumetric flow rate, pressure drop, wall shear stress, and the ratios of pressure drop and shear stress are obtained for the stenosed artery using the Einstein coefficient of blood viscosity. Additionally, variations in plasma viscosity and hematocrit are examined concerning these flow parameters in the stenosed artery region.These findings underscore the complexity of blood flow dynamics, emphasizing the critical importance of incorporating significant factors such as the Einstein coefficient of blood viscosity to advance our understanding of vascular physiology in the presence of stenosis.

Diabetes mellitus poses a significant risk for cardiovascular complications, including the formation of blood clots, which can lead to severe consequences such as heart attacks and strokes. In this study, we employ mathematical modeling and computational analysis to investigate the mechanisms underlying the increased risk of clot formation in diabetic patients. Our approach integrates physiological data, hemodynamic principles, and mathematical equations to simulate blood flow dynamics and clot formation processes within the vasculature of diabetic individuals. By incorporating key factors such as altered blood viscosity, resistance to flow, endothelial dysfunction, and platelet aggregation, we obtained insights into the complex interplay between diabetes related factors and clotting propensity. Changes in blood composition, such as increased levels of fibrinogen and other clotting factors, can make blood thicker and more prone to clotting and the reason for increased resistance to flow and viscosity. As blood clots enlarge in blood vessels, they obstruct blood flow, increasing resistance. This makes blood movement harder. Clot size also affects nearby blood viscosity. Accumulating cells and clotting factors thicken blood, worsening circulation. Larger clots heighten flow resistance and viscosity, potentially causing issues like tissue damage. Thus, larger clots worsen blood flow and cardiovascular health. Through computational simulations, we explored various scenarios to assess the impact of different parameters on clot formation risk, thereby offering valuable insights for the development of preventive strategies and targeted interventions for diabetic patients.

Kidney stone is an alarming global disease due to its rising incidence and prevalence. FTIR spectroscopic analysis reveals that calcium oxalate is one of the most frequent chemical constituents in kidney stones. DFT calculations indicate that the calcium oxalate can interact through charge transfer process in biological activities. Among various proteins, lysozyme is one of the promoter proteins in nephrolithiasis of calcium oxalate type kidney stone. The location, conformation and interactions of calcium oxalate with the active residues of lysozyme contribute the binding energy of -4.18 kcal/mol. The characterization of kidney stones, DFT calculations of calcium oxalate, and binding interactions of calcium oxalate-lysozyme complex contribute to the understanding of nephrolithiasis.
