Authors: Żatuchin Dmitrij 
Published: March 2024

Abstract
This study investigates the application of the SECI model in the design and execution of educational courses in "Innovation and Digitization Management" and "Data-Based Decision Making" micro-degrees developed in 2023 and 2024. Leveraging Natural Language Processing (NLP) and text analysis, we explore the patterns in course content that correlate with positive learner feedback and effective knowledge transformation. The methodology includes data preprocessing, tokenization, vectorization, and clustering to systematically compare and contrast course elements with learner feedback. Preliminary findings indicate that the integration of the SECI model, emphasizing real-time content sharing and example-based learning, significantly enhances the transfer of knowledge from tacit to explicit forms. This research aims to identify a replicable cadence in content preparation that optimizes learning outcomes.

Abstract
Objectives: Gestational diabetes mellitus (GDM) is a public health challenge that severely endangers the lives of mothers and children. In Ethiopia, its prevalence and predictors have scarcely been studied and have not been studied in the context of the present study. This study aimed to assess the prevalence and associated factors of GDM among pregnant women in Bule Hora, southern Ethiopia.
Results: A total of 190 pregnant women were interviewed and studied. The mean age of the pregnant women was 30.06 (SD ± 5.53) years. Approximately three-quarters (74.2%) of pregnant mothers were in their second trimester (24 -28 weeks) of pregnancy. Approximately a third, 31.6%, of the participants were overweight/obese with a mid-upper arm circumference (MUAC) measurement greater than or equal to 28 centimeters. The mean fasting blood sugar level was 83.46 (SD ± 8.84) mg/dL. The prevalence of GDM in this study was 7.4%. Family history of diabetes (AOR = 5.7; 95% CI: 1.28-25.27), elevated triglyceride concentration (AOR = 5.6; 95% CI: 1.258-25.46), history of having a macrosomic baby (AOR = 6.8; 95% CI: 1.56-29.59), and history of abortion (AOR = 4.4; 95% CI: 1.09-18.39) were factors associated with GDM.

Authors: Hua Xiuqin , Sun Dong , Liu Daqing , Ma Ning 
Published: March 2024

Abstract
The spectrum of surface plasmon polaritons in double-layer graphene with and without an external magnetic field by utilizing Maxwell’s equations in a hydrodynamic model was studied and field configurations were analyzed. There is neither a transverse magnetic (TM) mode nor a transverse electric (TE) mode but a full-field mode under the external field. Regardless of the presence or absence of an external field, the excited transverse magnetic field is symmetrical in the acoustic branch, whereas it is antisymmetrical in the optical branch. Meanwhile, the excited transverse electric field has opposite symmetry properties against to that of the transverse magnetic field. The results indicate that the rise of the spectrum is dominated by an external magnetic field in the infrared region and a non-local effect in the ultraviolet region. The influence of the layer distance on the spectrum was also studied.

Abstract

Diabetes is commonly associated with an elevated level of reactive carbonyl species due to alteration of glucose and fatty acid metabolism. These metabolic changes cause an abnormality in cardiac Ca2+ regulation that can lead to cardiomyopathies. In this study, we explored how the reactive α-dicarbonyl methylglyoxal (MGO) affects Ca2+ regulation in mouse ventricular myocytes. Analysis of intracellular Ca2+ dynamics revealed that MGO (200 µM) increases action potential (AP)-induced Ca2+ transients and sarcoplasmic reticulum (SR) Ca2+ load, with a limited effect on L-type Ca2+ channel-mediated Ca2+ transients and SERCA-mediated Ca2+ uptake. At the same time, MGO significantly slowed down cytosolic Ca2+ extrusion by Na+/Ca2+ exchanger (NCX). MGO also increased the frequency of Ca2+ waves during rest and these Ca2+ release events were abolished by an external solution with zero [Na+] and [Ca2+]. Adrenergic receptor activation with isoproterenol (10 nM) increased Ca2+ transients and SR Ca2+ load, but it also triggered spontaneous Ca2+ waves in 27% of studied cells. Pretreatment of myocytes with MGO increased the fraction of cells with Ca2+ waves during adrenergic receptor stimulation by 163%. Measurements of intracellular [Na+] revealed that MGO increases cytosolic [Na+] by 57% from the maximal effect produced by the Na+-K+ ATPase inhibitor ouabain (20 µM). This increase in cytosolic [Na+] was a result of activation of a tetrodotoxin-sensitive Na+ influx, but not an inhibition of Na+-K+ ATPase. An increase in cytosolic [Na+] after treating cells with ouabain produced similar effects on Ca2+ regulation as MGO. These results suggest that protein carbonylation can affect cardiac Ca2+ regulation by increasing cytosolic [Na+] via a tetrodotoxin-sensitive pathway. This, in turn, reduces Ca2+ extrusion by NCX, causing SR Ca2+ overload and spontaneous Ca2+ waves.

Published: March 2024

Abstract
Lightweight geopolymer has the advantages of wide source of raw materials, chemical corrosion resistance, high mechanical strength and excellent durability, which is expected to replace traditional building insulation materials. In this paper, green bio-based foaming agents with small 1h settlement distance, high average foaming multiple and low bleeding ratio were obtained by Cetyltrimethylammonium Bromide/yeast solution. When the amount of Cetyltrimethylammonium Bromide is 0.50 wt%, the foams prepared by the yeast and Cetyltrimethylammonium Bromide composite system exhibit the improved 1h settlement distances, the large average foaming multiple, the small bleeding ratio and uniform size. Subsequently, lightweight geopolymer was successfully prepared by the bio-based foaming agents, and the effects of different foam contents on the properties of geopolymer such as dry density, water absorption, thermal conductivity, compressive strength, and morphology were studied. With the increase of foam content, the dry density, thermal conductivity and compressive strength of the geopolymer gradually decrease, the water absorption increases, regardless of whether to add silica fume or fly ash. Herein, it is confirmed that the foaming agent based on yeast can be effectively used to prepare lightweight geopolymers, which can provide vast opportunities to turn into candidates for the novel inorganic thermal insulation material.

Abstract

The recent emergence of concrete-filled steel tube (CFST) columns represents a significant advancement in composite column technology. This innovative approach synergistically combines concrete and steel, where the steel tube acts as a confining medium that enhances the concrete's strength and ductility, while the concrete in turn mitigates the risk of both internal and local buckling in the steel tube. The primary benefits of CFST columns over traditional concrete columns include the elimination of the need for reinforcement and formwork, faster construction times, cost savings, reduced column dimensions, and improvements in load capacity, ductility, and energy absorption capabilities. This research investigates the impact of T-type steel stiffeners on the behavior of square CFST columns through numerical modeling. Utilizing the ABAQUS software, the study analyzed ten specimens to understand this effect comprehensively. A total of fifty CFST specimens reinforced with T stiffeners were modeled to assess varying parameters, such as wall thickness, stiffener depth, and steel grade, under axial loads and bending moments. For each specimen, a P-M (axial force-bending moment) diagram was generated. The outcomes of this analysis culminate in the proposal of an axial force-bending moment interaction diagram specifically for CFST columns reinforced with T stiffeners, providing valuable insights for the design and application of these columns in structural engineering.

Abstract
Data outsourcing become more and more popular due to its low cost and flexibility. However, there is a problem that the cloud server used to store data is partially trusted. Searchable encryption is an efficient technology is devoted to helping people conduct accurate searches without leaking information. Nonetheless, most existing schemes can’t support dynamic update or meet the privacy requirements of all users. There have been some experiments to solve these issues by implementing a dynamically searchable asymmetric encryption scheme. This paper proposes an efficient searchable encryption scheme based on the Authen-ticator Bloom Filter (ABF). The solution can support dynamic update, multiuser and meet the forward and backward security. This paper uses ABF to improve the efficiency of search and update, while playing a significant role in dynamic update. This paper designs a new token encryption scheme and file set encryption scheme, which not only helps users reduce time in search and update, but also supports multiuser mode. Experiments show that the proposed scheme takes less time in searching and updating algorithms, especially when the keyword does not exist. The solution also takes into account the problem of history storage when updating, which reduces the unnecessary consumption of memory and avoids multiple storage states of the same file.

Abstract
As incoming in our study, practically synthesized borosilicate was boosted with traces of titanium and zirconium (BSZT) is conducive to promoting a cutting-edge mock-up of laboratory boron silicate glassware. Getting into boron silicate glassware manufacturing at 1500 C is urgently entailed. But take a seeing at BSTZ processing, which has performed extremely well at 900 °C given that sodium met silicate is employed as a flux and silicate content enrichment. And yet still, the silica percentage is set below 84%, borate at about 8 %, and Ti and Zr are set to be 9% en masse. For adsorption and desorption studies, a battery of experiments is exquisitely triggered amongst solution pH, working time, boron silicate weights, and chromium concentration. To test out modified borosilicate morphology, delving into bonds, and surface characterization, different screening tools such as FTIR, SEM, EDS, and BET have been well run. Interestingly, the modified boron-silicate surface expedites chromium adsorption within 30 sec. to trigger 65% adsorption efficiency and 60 mg/g uptake. In studies of adsorption isotherms, chromium ions get along well with the Langmuir model rather Freundlich model. Kinetics findings confirm that adsorption is chemical and conducive to pseudo-second-order. The upcoming thermodynamics findings outline the exothermic nature of chromium adsorption over modified borosilicate.

Abstract
Context
Sustainable rural development, closely linked to well-being of both urban and rural residents, is essential to achieving regional sustainability. Understanding the spatial characteristics vital for rural sustainability is fundamental to rural sustainability assessment, regional ecosystem services provisioning, and human well-being research.
Objective
This study aimed to construct an indicator system to assess rural sustainability from multiple stakeholders' perspectives, and examine the spatial characteristics that affect rural sustainability from the perspectives of villagers, tourists, and the government.
Methods
This study proposed indicator systems for each group of stakeholders at the scale of administrative villages. It assessed the rural sustainability of Huzhou, one of China's most developed rural areas, by using multi-source and innovative datasets. Spatial heterogeneity of rural sustainability was examined by hot spots and gradient analysis and the spatial characteristics of rural landscapes were quantified from the dimensions of natural, humanistic, and infrastructural characteristics. The spatial random forest model was adopted to identify effects of different spatial characteristics on rural sustainability.
Results
Our results showed that hot spots of rural sustainability mainly concentrated in proximity to urban areas and scenic spots, showing a decreasing and then increasing trend with increasing distance. Compared with humanistic and infrastructural characteristics, natural characteristics of villages were more important to rural sustainability. The relationship between rural sustainability and spatial characteristics varied among different stakeholders. Natural characteristics had the greatest impact on rural sustainability from the perspectives of villagers and tourists, and humanistic and natural characteristics were more important from the perspective of governments.
Conclusion
This study revealed the relationship between rural sustainability and spatial characteristics at the administrative village scale from multi-stakeholder perspectives, which helps to guide rural landscape planning and governance, and improve the contributions of rural landscapes to regional sustainability.

Abstract

Capsules have been investigated as a popular oral dosage form among communities due to their simplicity and ease of production. Capsules that are considered in the gastro-resistance category can be very beneficial due to enhanced drug absorption, improved stability, targeted release, etc. This study investigated the effect of enteric polymers on uncoated hard capsule fabrication and dissolution properties. The polymers used in this study included HPMCPh and Eudragit L100-55. Eight different formulations based on HPMCPh, Eudragit, and gelatin were examined to identify the ideal formulation for the product of uncoated enteric hard capsules with preferred physicochemical and gastro-resistance properties. The results reveal that the capsules containing Eudragit (F1), HPMCPh (F2), Eudragit/HPMCPh/gelatin (F3), and Eudragit/gelatin (F4) are steady within the simulated stomach environment, and drug release does not occur for 120 minutes. The outcomes demonstrate that, among the proposed formulas, the F4 formula is suitable both in terms of capsulation form and delayed release properties and shows no microbial growth. The properties of the optimized sample were studied by FTIR, FESEM, tensile strength, humidity, and rheology. The results illustrated that gelatin-based hydrogels with Eudragit (F4) are potential candidates for manufacturing uncoated enteric hard capsules that inhibit drug release in a gastric pH medium and act as a pH-sensitive drug release system.

Abstract
The herbal supplements can attenuate alcohol-related traumatic organ damages. In this study, we aimed to investigate the therapeutic role of hawthorn (SCE) against alcohol-induced neurotoxicity. Sprague Dawley rats received a single dose of ethanol (4.5 g/kg, intragastric) and were then administered orally standardized SCE for 20 days. At the end of experiment, brain samples were removed for biochemical, histological, immunofluorescence, histochemical and immunuhistochemical analyzes in rats. SCE significantly reduced the levels of 6-keto prostaglandin F1 alpha (6K-PGF1) and thromboxane B2 (TXB2), which were increased in brain by ethanol exposure. SCE administration ameliorated neuroinflammation and provided significant decreases the raised levels of Tumor necrosis factor-alpha (TNF-α) and Interleukin 1 beta (IL-1 β). Superoxide dismutase (SOD) and glutathione (GSH) contents were negatively correlated with the MDA concentration after oral adminstration of plant extract. Myelin damage and severe pathological findings following alcohol intoxication weren’t observed. Our study provide, the first evidence of effectiveness SCE in rat brain against alcohol injury. Its mechanisms may be related to improvement of vascular function, reduction in inflammatory reaction, antioxidative activity, anti-genotoxicity, myelin regeneration and also anti-apoptotic effects. In conclusion, SCE is a targeted and promising drug to treat brain necrosis due to alcohol usage. SCE seems to counteract the deleterious effects of ethanol on brain tissue through different cellullar and signaling mechanisms and thus can be used as a thearupatic practice against alcohol toxicity.

Abstract

Isotopic activity ratios of the relevant radionuclides, detected at radionuclide stations within the international monitoring system (IMS) for the Comprehensive Nuclear-Test-Ban Treaty, play a crucial role in characterizing release events under assumed scenarios. This analysis involves radioactive gases initially released from an underground nuclear event resulting in radionuclide concentrations in a plume of air passing over an IMS station that are subsequently sampled by that station. Modeling this requires considering the post-shot radionuclide evolution of an assumed underground nuclear explosion, the simulations of atmospheric transport modelling, and, finally, the sample measurement. Activities collected in the samples are determined through spectrum analysis of sample measurements, and the activity concentrations are then estimated by assuming a constant concentration during sampling. While this assumption holds for radionuclides with relatively longer half-lives, that is, exceeding 7 times the sampling duration, challenges arise for the isotopes with short half-lives, such as 135Xe with half-life of 9.14 hours compared to the 12-hour collection duration for some noble gas systems. Therefore, this study investigates the decay correction during sampling using two approaches, 1) Interval constant concentration: the collection duration is divided into multiple intervals with a constant concentration assumed in each interval; 2) Decaying concentration: the activity collected in the sample is derived based on an analytical solution to the ordinary differential equations of the activity decay and ingrowth. The impact of these approaches on isotopic activity ratios is demonstrated in three cases with short half-lives, 140Ba/140La, and 133mXe/133Xe, and 135Xe/133Xe.

Abstract
In recent years, emotion recognition as a new method for natural human-computer interaction has attracted the attention of many researchers. Because the automatic recognition of emotion from speech or facial expressions alone has uncertainties; it is expected that emotion recognition based on the fusion of audio-visual information can be done with better accuracy. The purpose of this article is to present an efficient method for emotion recognition from emotional speech signals and images of emotional facial expressions, based on the SOAR cognitive science model. In this article, in order to implement the subsections of the SOAR model, stochastic deep learning has been used. In the proposed model, the RAVDESS database is used for testing and evaluation, and we have achieved 89.44% accuracy in the evaluation.
