Published: February 2024

Abstract
Due to the high rate of waste glass of mobile in each year, using this wasting material in different ways can be helpful for the environment and human health. So that investigating the use of waste glass of mobile for shielding usages has been hardly regarded in recent years. In this study, the effect of different Bi2O3 contents (0–20 mass percentage) evaluated on the radiation protection ability and physical properties of an important recycling waste phone glass Bi2O3-SiO2-B2O3-ZnO-Al2O3 using Monte Carlo based code (MCNPX 2.6.0) and online Phy-X/PSD program has been investigated. Radiation shielding properties of glass compositions (equivalent atomic number, Half Value Layer, Mean Free Path, Linear Attenuation Coefficient, Exposure and energy absorption buildup factors, and Mean Free Path) investigated for wide various range of photon energies of medical energies from 0.015 up to 15MeV. By compassion of derived results with similar studies it was obviously shown that WCG with 20% of Bi2O3 content is the best material for gamma and neutron shielding usage.

Published: February 2024

Abstract
While the significance of competition for resources in shaping the structure of aquatic ecosystems is well recognized, its specific effects on the dynamics of allochthonous matter in streams have received limited attention and remain poorly understood, mainly between interspecific and intraspecific competition. In this study, we investigated the effects of interspecific and intraspecific competition on the shredder organisms Phylloicus and Aegla in leaf litter banks. The impact of competition was assessed through experimental treatments: i - Phylloicus competition-free; ii - Aeglacompetition-free; iii - intraspecific competition within Aegla; iv - intraspecific competition within Phylloicus; v - interspecific competition. In the competition-free treatment, a single organism was placed in a 2-L microcosm, whereas in the competitive pressure treatments, two organisms were placed in a 4-L microcosm, with a 0.05-mm mesh separating them. Our results revealed that interspecific competition had a greater impact on Phylloicus, while intraspecific competition exerted a stronger influence on Aegla. Phylloicusexhibited higher efficiency as a shredder compared to Aegla, which can be attributed to its broader feeding range and unique strategies in leaf litter utilization. The presence of potential competitors led to a reduction in consumption rates in Phylloicus, indicating its sensitivity to competition. Moreover, Aegla's predatory behavior and cannibalism may intensified intraspecific competition within the species. The findings highlight the importance of competition in shaping the feeding activity of shredder organisms in leaf litter banks, which ultimately affects nutrient cycling in aquatic ecosystems.

Published: February 2024

Abstract

In this article, the concept of gravitational fields applied to trade is revisited and extended to multiple economic variables, integrated within Moran’s I analysis. Following Isard’s thinking, emphasis is placed on the use of the gravitational model in spatial analysis, with the intent of theoretically developing an econophysical methodology. To map the interactions between the economic forces generated by the individual gravitational fields of various regions, the principle of vector superposition is applied to provide the resulting total field. Through a cross-analysis that employs gravitational fields and Moran's I, spatial concentration phenomena in the American market will be studied.

Published: February 2024

Abstract
The mortality rate among patients with cervical cancer (CVC) is a significant concern among female malignancies, posing a substantial threat to women's well-being. Human papillomavirus (HPV), a non-enveloped double-stranded DNA virus with epithelial characteristics, has been identified as a causative factor in CVC, primarily through persistent high-risk HPV infection. This study investigated the potential anti-CVC effects of CA in vitro and in vivo using the HPV-positive CVC cell line HeLa according to colony formation and cell wound healing, target fishing, molecular docking, network pharmacology analysis, cellular thermal shift, RNA interference and quantitative reverse transcription-polymerase chain reaction, immunofluorescent staining, immunohistochemical staining and xenografts assays. We found that CA could impede proliferation, induce cell cycle arrest, and prompt apoptosis by inhibiting the PI3K/Akt signaling pathway. Target fishing and molecular imaging utilizing an alkynyl-CA probe revealed the ribosomal protein S16 (RPS16) as a CA target, mediating the degradation of E6 and E7 proteins. The covalent binding of CA to RPS16 led to alterations in its stability. These findings highlight the huge potential of CA in designing and developing lead compounds for this patient population and suggest RPS16 as a novel therapeutic target.

Published: February 2024

Abstract
Background
Tuberous sclerosis complex (TSC) is a genetic multisystem disorder characterized by widespread hamartomas in several organs. The variety of clinical manifestations makes it challenging to establish a definite clinical diagnosis. To our knowledge, there have been no previous reports of adult-onset TSC presenting with panic-like symptoms as the chief complaint and a combination of cognitive impairment and affective symptoms.
Case Presentation:
A 26-year-old unmarried Han Chinese female had suspicious panic-like symptoms over two years. There was persistent concern about the above symptoms. The depressive syndrome was followed a year ago. No aura, loss of consciousness, foaming at the mouth, motor paresthesia, or psychotic symptoms were reported in the course of the disease. The hospitalization was due to poor response to repeated outpatient visits. On physical examination after admission, several hypomelanotic macules were found on the patient's body. Auxiliary examinations suggestive of abnormalities include epileptic waves detected by electroencephalogram and scattered nodules detected by imagological examinations. The cognitive test indicated borderline intelligence. A rare genetic variation (TSC1 c.2625 + 367A > G) was also found. The patient was eventually diagnosed with tuberous sclerosis complex. After treatment with slow sodium channel blockers and serotonin and norepinephrine reuptake inhibitors, the focal seizure and affective symptoms were well controlled, while the cognitive function needed further long-term follow-up.
Conclusion
Clinicians should recognize that TSC is a multisystem disorder that may manifest multiple complaints. We report an adult-onset TSC with multi-neuropsychiatric symptoms and provide learnable points for clinicians from aspects of clinical manifestations, imaging, and genetics.
Solar Radiation and Geomagnetic Contribution of Consecutive 27-Day Recurrent Geomagnetic Storms to Variations of Equatorial Ionospheric Parameters and Spread F
Authors: YEERAM THANA 
Published: February 2024

Abstract
This study investigates solar radiation and geomagnetic effects of consecutive 27-day recurrent geomagnetic storms (RGSs) during 2007 on the variabilities in the equatorial ionospheric F-region in American Peruvian sector. Results show correspondence of quasi-periodic variations between geomagnetic activities and ionospheric responses in the F-region. In High-Intensity Long-Duration Continuous (AE) Activity (HILDCAA) events, the ionospheric responses are more variable than in non-HILDCAA. The critical frequency and peak heights of the F-layer tend to increase during storm-time in summer months, but decrease in response to enhanced equatorial electrojets. A new classification of daily variations in the virtual height of the F-layer (h′F) is proposed: (mode A) mixing of great height before noon and low height before midnight, (mode B) moderate height before midnight, and (mode C) mixing of low height before noon and great height before midnight. These (h′F) modes efficiently characterize ionospheric variabilities and processes. The great uplifts of (h′F) during night-time coincide with the presence of strong disturbance dynamo electric fields and disturbed neutral winds generated by intensified Joule heating in the summer months. The solar EUV plays a role in the uplifts during daytime. Zonal electric field disturbances and perturbations in neutral meridional winds critically contribute to the equatorial ionospheric responses and ESF variability. Most of inhibited/suppressed ESF occurred in mode A and in overshielding conditions. The inhibited ESF in the recovery phase is mainly contributed by a cooling state after great uplifts by daytime thermospheric winds.

Abstract
The Sixth Assessment Report of the Intergovernmental Panel on Climate Change highlights the reliance on optimistic scenarios such as shared socioeconomic pathways SSP1-1.9 and SSP1-2.6 to achieve the 1.5°C or 2°C climate targets by the end of this century[1]. However, these scenarios have not quantitatively assessed the impact of global tensions (measured as global military expenditure as a percentage of GDP) on CO2 emissions. Our research reveals that events such as the 2001–2011 War on Terror and the 2021 prelude to the Russian–Ukrainian war have led to a 0.041% (95% CI: 0.030–0.052) kg/USD increase in CO2 emission intensity (CO2 emissions per unit of GDP) for each 1% rise in global tensions. This increment accounts for 30% of the total change in CO2 emission intensity from 1995 to 2021. In the case of escalating global tensions, with the global military expenditure ratio exceeding thresholds of 11% (for SSP1-1.9) or 23% (for SSP1-2.6), the global surface temperature increase would fail to return below 1.5°C after the initial overshoot in SSP1-1.9, and the 2°C climate target would become unattainable in SSP1-2.6 by the end of this century. These findings underscore the potential of escalating global tensions to undermine climate targets, emphasizing the critical need for a more peaceful international environment to effectively limit global warming to 1.5°C or 2°C.

Published: February 2024

Abstract
Polygonatum cyrtonema is a medicinal plant and its polysaccharides are used for immunomodulation and the treatment of hypoglycemia. Investigation of the tissue distribution and pharmacokinetics of P. cyrtonema polysaccharide can further elucidate its pharmacological mechanism. A fluorescence labeling approach using rhodamine B (RhB) as a fluorescent molecular probe was used for the quantitative assessment of the polysaccharide from dried P. cyrtonema (DPC1) samples, and the pharmacokinetics and tissue distribution of DPC1 were evaluated in mice after intraperitoneal or oral administration. DPC1 was successfully labeled with RhB, showing degrees of fluorescence labeling at 0.453% and 0.568% as determined by the ultraviolet and enzyme marker methods, respectively. DPC1-RhB was rapidly absorbed into the bloodstream after oral and intraperitoneal administration. The relative bioavailability of DPC1-RhB was as high as 48.648%, showing linear pharmacokinetic characteristics. After administration, DPC1-RhB was primarily distributed in the tissues of the heart, spleen, and lung, indicating that the drug has a targeted effect on these tissues. Overall, the findings provide a comprehensive reference for the in vivo distribution of DPC1, together with a foundation for further elucidation of its pharmacological mechanism and the development and application of DPC1 formulations.

Published: February 2024

Abstract
Public transportation systems play a vital role in modern cities, enhancing the quality of life and fostering sustainable economic growth. Modeling and understanding the complexities of these transportation networks are crucial for effective urban planning and management. Traditional models often fall short in capturing the intricate interactions and interdependencies in multi-modal public transportation systems. To address this challenge, recent research has embraced multi-layer network models, offering a more sophisticated representation of these networks. However, there is a need to explore and develop robustness analysis techniques tailored to these general multi-layer networks to fully assess their complexities in real-world scenarios. In this paper, we employ a general multi-layer network model to comprehensively analyze a real-world multi-modal transportation network in Seoul, South Korea. We leverage a large volume of traffic data to model, visualize, and evaluate the city's mobility patterns. Additionally, we introduce two novel methodologies for robustness analysis, one based on random walk coverage and the other on Eigenvalue, specifically designed for general multi-layer networks. Extensive experiments using the large volume of real-world data sets demonstrate the effectiveness of the proposed approaches.

Authors: Kara Yusuf Alper , Ergun Ergun , Ozguner Ismet Faruk 
Published: February 2024

Abstract
Background
Oral intake of corrosive substances is an important cause of morbidity and sometimes mortality in childhood. Early evaluation is important in determining the course of possible damage. This study aimed to compare early endoscopic evaluation and clinical observation methods in patients with corrosive substance ingestion.
Methods
Seventy-five patients with corrosive substance ingestion were hospitalized in a tertiary pediatric surgery clinic between January 2019 and December 2020. They were enrolled in a prospective randomized controlled manner, 35 of whom were in the endoscopy group and 40 in the clinical observation group, and their data were collected after obtaining consent from their families.
Results
It was observed that the most common chemical agents in hospitalized patients with a history of corrosive substance intake were dish polishers and sink openers, and contact with strong alkaline substances was the most common case. Endoscopic evaluation increased the total cost compared to clinical observation but decreased the nil per oral duration, the number of drugs they took, and the inpatient duration (p < 0.05). Neither the presentation symptoms nor physical examination findings were to the pH level of the corrosive substance ingested (p > 0.05).
Conclusions
Endoscopic evaluation could be a choice for reducing the length of hospital stay, drug doses, and the nil per oral period, but it increases the total cost. Since no cases with significant esophageal damage were detected in our clinic at the time of this study, the results should be supported by larger series.
