Tailoring of Structural and Optical Properties of Electrosprayed β-Ga2O3 Nanostructures via Self- Assembly
Authors: Kumar Ashish , Singh Lokendra , Bag Ankush 
Published: January 2023

Abstract
The present article demonstrates the fabrication of various β-Gallium Oxide (Ga2O3) nanostructures (NSs) by low-cost and scalable electrospraying (ES) methods via self-assembly (SA). The effect of the annealing sequences on the self-assembled β-Ga2O3 NSs has been detailed. The comparative studies of NSs and nanoflakes (NFs) growth with annealing effect at different stages of self-assembly time (SAT) have been explored further. The fabricated NSs and NFs have been investigated using x-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The comparative study of categorized growth samples shows better crystalline quality when moving from the category 1 (C1) sample to the category 3 (C3) sample. The annealing sequences with SAT play a significant role in crystal formation and its quality, optical properties, and morphology of the Ga2O3 NSs. The optical properties of NSs have been derived from the normal incidence of absorbance measurements. The maximum observed energy band gap is ~5.40 eV. Traps and impurities play a critical role in the formation and deformation of energy bands in crystals. The photoluminescence (PL) spectra further reveal the variation in the intensity of luminescence of different emission bands due to the variation in the number of defect states and impurities in the NSs.

Abstract

Purpose:We investigated the differences in functional connectivity based on the source-level electroencephalography (EEG) analysis between stroke patients with and without post-stroke epilepsy (PSE).
Methods: Thirty stroke patients with PSE and 35 stroke patients without PSE were enrolled. EEG was conducted during a resting state period. We used a Brainstorm program for source estimation and the connectivity matrix. Data were processed according to EEG frequency bands. We used a BRAPH program to apply a graph theoretical analysis.
Results: In the beta band, radius and diameter were increased in patients with PSE than in those without PSE (2.699 vs. 2.579, p=0.003; 2.261 vs. 2.171, p=0.003). In the low gamma band, radius was increased in patients with PSE than in those without PSE (2.808 vs. 2.617, p=0.004). In the high gamma band, the radius, diameter, eccentricity, and characteristic path length were increased (1.828 vs. 1.559, p=0.001; 2.653 vs. 2.306, p=0.002; 2.212 vs. 1.913, p=0.001; 1.425 vs. 1.286, p=0.002), whereas average strength, global efficiency, local efficiency, mean clustering coefficient, and transitivity were decreased in patients with PSE than in those without PSE (49.955 vs. 55.055, p=0.001; 0.756 vs. 0.827, p=0.001; 4.795 vs. 5.741, p=0.002; 0.727 vs. 0.810, p=0.001; 1.091 vs. 1.215, p=0.001). However, in the delta, theta, and alpha bands, none of the functional connectivity measures were different between groups.
Conclusion: We demonstrated significant alterations of functional connectivity in patients with PSE, who have decreased segregation and integration in brain network, compared to those without PSE.

Published: January 2023

Abstract
The response of a raft foundation to seismic loading, and examines the changes in soil consideration and importance factor suggested in the latest seismic codes, IS 1893-2002 and IS 1893-2016. The two methods of analysis suggested by IS 2950-1981 code, rigid and flexible approaches for vertical and evenly distributed loads are examined. Literature review reveals that soil-structure interaction and finite element analysis are used in analysis and design of raft foundation. A case study is conducted to compare the manual calculations and rigid method with finite element methods and soft computing techniques. The results of the study conclude that the deflection, bending moment and soil pressure per meter width are effectively expressed in terms of relative stiffness factor, and that the magnitude of maximum bending moment increases with increase in the relative stiffness. The established variation patterns of contact pressures may not be applicable for raft under dynamic loading condition.
One-step Multiple Kernel k−means Clustering Based on Block Diagonal Property
Authors: Chen Cuiling , Wei Jian , Li Zhi 
Published: January 2023

Abstract
Multiple kernel k-means clustering (MKKC) can effiffifficiently incorporate multiple base kernels to generate an optimal kernel. However, many existing MKKC methods all need two-step operation: learning clustering indicator matrix and performing clustering on it. These results are not necessarily optimal because the optimal values of two steps are not equivalent to those of original problem. To address this issue, in this paper we propose a novel algorithm named one-step multiple kernel k-means clustering based on block diagonal property(OSMKKC-BD). By imposing a block diagonal constraint on the product of indicator matrix and its transpose and enhancing its block diagonalization, this algorithm can promote the indicator matrix to get explicit clustering indicator, so as to implement one-step clustering. Furthermore, a simple kernel weighting strategy is used to obtain an optimal kernel, and boosts the quality of optimal kernel. In addition, a three-step iterative algorithm is designed to solve the corresponding optimization problem, in which the Riemann conjugate gradient iterative method is used to solve the optimization problem about the indicator matrix. Finally, by extensive experiments on ten real data sets and comparison of clustering results with the state-of-the-art MKKC methods, it is concluded that OSMKKC-BD is effffective.

Abstract
Purpose
Neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) are widely accepted indices positively correlated with the disease severity, progression, and mortality. Since in a previous study we had correlated nutritional parameters with morbidity and mortality in cardiac surgery patients, we decided to perform a post-hoc analysis to test whether these parameters are also correlated with the NLR and PLR indices.
Methods
NLR and PLR were calculated on days 0, 3, 5, and 7 postoperatively. ROC curve was generated to assess their prognostic value and multivariate logistic analysis to identify independent risk factors for 90day mortality.
Results
Analysis was performed on 179 patients-data, 11 of which (6.15%) died within 90 days. The discriminatory performance for predicting 90day mortality was better for NLR7 (AUC = 0.925, 95%CI: 0.865–0.984) than for NLR5 (AUC = 0.810, 95%CI: 0.678–0.942), the respective cut-off points being 7.10 and 6.60. PLR3 exhibited a significantly strong discriminatory performance (AUC = 0.714, 95%CI: 0.581–0.847), with a cut-off point of 126.34. Similarly, a significant discriminative performance was prominent for PLR3, NLR5, and NLR7 with respect to the length of hospital stay. Moreover, NLR7 (OR: 2.143, 95% CI: 1.076–4.267, p = 0.030) and ICU length of stay (OR:1.361, 95% CI: 1.045–1.774, p = 0.022) were significant independent risk factors.
Conclusion
NLR and PLR are efficient predictive factors for 90day mortality and hospital length of stay in cardiac surgery patients. Owing to the simplicity of determining NLR and PLR, their postoperative monitoring may offer a reliable predictor of patients’ outcomes in terms of length of stay and mortality.

Abstract
Government is always the biggest spending agency in many countries, and this signifies a huge opportunity for government procurement fraud. Failure to implement strong measures for fraud prevention may lead to financial losses and a bad reputation for the country. In Indonesia, procurement fraud has been classified as one of the major components of fraud. Therefore, there is a crucial need for extensive studies to understand factors that may contribute to the fraud prevention strategy among government agencies in Indonesia. This paper examines three factors that may promote procurement fraud prevention among government agencies in Palembang City. The three factors are top management competencies, e-procurement and internal control system. Questionnaires were distributed to employees in the procurement department of 51 government agencies in Palembang, the most reported procurement fraud cases in Indonesia. Data were thoroughly analysed using multiple regression analysis with the SPSS analysis tool. The finding revealed that internal control systems and e-procurement significantly contributed to fraud prevention programs. However, the top management competencies showed a negative relationship with procurement fraud prevention. In addition, this study found the implementation of e-procurement and internal control systems was an important tool in to fight against fraud. This study contributes to the literature by providing empirical support in confirming the critical role of the internal control system and e-procurement in enhancing fraud mitigation mechanisms.

Abstract

Background Retirement is associated with a more passive lifestyle, and may therefore lead to weight gain. This study aims to investigate longitudinal associations between changes in 24-h movement behaviors and obesity indicators in relation to the transition from work to retirement. Methods The study population included 213 retiring public sector workers (mean age 63.5 years, standard deviation 1.1) from the Finnish Retirement and Aging study. Before and after retirement with a 1-year lag, participants wore an Axivity accelerometer on their thigh and filled in a daily log for at least four days to measure daily time spent sleeping, in sedentary behavior (SED), light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA). Also their body mass index (BMI) and waist circumference was measured twice. Compositional linear regression analysis and isotemporal substitution analysis were used to study associations between changes in 24-h movement behaviors and changes in obesity indicators. Results An increase in MVPA in relation to sleep, SED and LPA was associated with a decreasing BMI (β=-0.60, p = 0.04) and waist circumference (β=-2.14, p = 0.05) over one year from before retirement to after retirement. In contrast, increasing sleep in relation to SED, LPA and MVPA was associated with an increasing BMI (β = 1.34, p = 0.02). Reallocating 60 minutes from MVPA to SED or sleep was estimated to increase BMI by on average 0.8 − 0.9 kg/m2and waist circumference by 3.0 cm during one year. Conclusions In the transition from work to retirement, increase in MVPA and sleep in relation the remaining behaviors were associated with improvement and worsening, respectively, in obesity indicators. Common life-transitions, like retirement, should be taken into account, when giving recommendations and guidance for physically active life style and sleep.
A Pattern of Stable Isotopes and a Helical Toroidal Wave Orbital model
Authors: Lin Jingfeng , Lin Guangyi 
Published: January 2023

Abstract
We investigate a pattern of isotopes with the highest isotopic abundance, the number of nucleons of some stable nuclides tends to A = S(S + 1)-2, this means that S is probably the number of shells. Therefore, we present an arrangement pattern of the magic numbers. Further, based on some simple patterns in atomic nuclei, such as shell structures, magic numbers and collective modes, we developed a helical toroidal wave orbital model to explore the microstructure of isotopes that matches the proposed arrangement pattern.
On the use of surface roughness parameters
Authors: Persson B. N.J. 
Published: January 2023

Abstract
In most practical applications surface roughness is characterized by just one or two parameters (numbers). I show that the standard maximum surface height parameters fluctuate strongly between different surface realizations (or measurements), and should not be used in the design of engineering components. I show how some roughness parameters depends on the size of the roll-off region in the surface roughness power spectra, and introduce a new height parameter which is very reproducible. The numerical results presented agree well with experimental observations.

Published: January 2023

Abstract:
Neurodegenerative disorders (NDDs) are multifaceted complex disorders that have put a
great health and economic burden around the globe nowadays. The multi-factorial nature of NDDs has
presented a great challenge in drug discovery and continuous efforts are in progress in search of suitable
therapeutic candidates. Nature has a great wealth of active principles in its lap that has cured the
human population since ancient times. Natural products have revealed several benefits over conventional
synthetic medications and scientists have shifted their vision towards exploring the therapeutic
potentials of natural products in the past few years. The structural mimicking of natural compounds to
endogenous ligands has presented them as a potential therapeutic candidate to prevent the development
of NDDs. In the presented review, authors have summarized demographical facts about various
NDDs including Alzheimer’s disease (AD), Parkinson’s disease (PD), Huntington’s disease (HD) and
various types of sclerosis in the brain. The significant findings of new active principles of natural
origin along with their therapeutic potentials on NDDs have been included. Also, a description of clinical
trials and patents on natural products has been enlisted in this compilation. Although natural products
have shown promising success in drug discovery against NDDs, still their use is associated with
several ethical issues which need to be solved in the upcoming time.

Authors: Olatubi Matthew Idowu , Alabi Boluwatife Deborah , Ademuyiwa Grace Oluwaranti , Ojo Iyanuoluwa Oreofe 
Published: January 2023

Aim:
This study assessed the prevalence and management of LBP among health workers in a private teaching hospital in South West Nigeria.

Background:
Healthcare workers (HCWs) often experience low back pain (LBP) more than any other category of workers. While a lot has been documented about the prevalence of LBP among different categories of workers, little is known about how health workers manage LBP.

Objectives:
This study aimed to assess the prevalence and management of LBP among health workers in a private teaching hospital in South West Nigeria. Associations between variables: (a) sociodemographic variables (i.e., age, gender) and the prevalence of low back pain, and (b) interference with activities of daily living across different categories of health workers, were evaluated.

Methods:
A cross-sectional design was employed in this study. One hundred and eighty-nine HCWs were randomly selected from the wards and units of the hospital. The LBP questionnaire and the Nordic Musculoskeletal questionnaire were used for data collection. Data were analysed using descriptive (mean and percentages) and inferential (chi-square and ANOVA) statistics.

Results:
The prevalence of LBP among health workers was found to be 87.3%. Moreover, most of the health workers massage their back (78.3%), engage in exercise (72.0%), and use analgesics (69.3%) as a means of managing LBP. Furthermore, there was no significant relationship between gender (X2 = 0.31, P>0.05), age (X2 = 1.52, P>0.05), marital status (X2 = 2.93, P>0.05) of HCWs and prevalence of LBP. However, a significant difference was reported in the mean interference of LBP with activities of daily living across the different categories of healthcare workers that participated in the study (F= (7,181) 3.58, P = 0.01).

Conclusion:
The prevalence of LBP is high among HCWs that participated in the study. Therefore, it is recommended that HCWs might use massage, engage in exercise, and take analgesics as a means to combat LBP.
Conventional vs. Microwave-assisted Synthesis: A Comparative Study on
The Synthesis of Tri-substituted imidazoles
Authors: Bansode Deepali , Goel Tanvi , Jain Naman Vijaykumar 
Published: January 2023

Background:
The organic and peptide synthesis, various nanotechnology, and biochemistry processes are being carried out using microwave irradiation. The use of microwaves for synthesis has increased in the past two decades. The microwave offers several advantages such as ease of handling, lesser reaction times, quality of the product, and eco-friendly, which is green. The conventional method of synthesis, on the other hand, requires a longer time, is difficult to handle and maintenance of temperature is also difficult. The use of microwave-assisted reactions over conventional methods is advantageous in medicinal chemistry research as they will be less time-consuming and crucial in drug discovery and development. On the other side, they might not work in bulk synthesis due to their limited capacity for loading the reaction mixture.

Objective:
The present work aims to compare reaction time, temperature and percentage of yield of the microwave-assisted synthesis method against the conventional method.

Method:
A novel, simple, and green method was developed for the synthesis of tri-substituted imidazoles by microwave irradiation. Both derivatives from conventional and microwave-assisted synthesis were characterized by IR spectroscopy, Mass spectrometry, and 1H-NMR spectroscopy. The same derivatives were also synthesized by the conventional method for comparison.

Result:
A comparison of both methods was made by comparing the reaction time and the percentage yield. It was found that microwave-assisted reactions produced greater yield in the minimal time, though at different reaction temperatures.

Conclusion:
It can be concluded from the present comparison study that the use of the microwave for synthesis provides numerous advantages; thus, newer molecules are developed quickly anthat are developed quickly. To further proceed in this direction and to produce evidences, synthesis of more derivatives may be required. The only disadvantage is that it cannot be used for bulk synthesis of the compounds.
