Authors: Iskamto Dedi , Aftanorhan Asyraf , Ghazali Puspa liza 
Published: December 2022

<p>This study aims to examine the mediating role of SME performance in the relationship between entrepreneur competence (EC) and satisfaction (ES) in Indonesia. Data were analyzed using Structural Equation Modeling (SEM), AMOS 24. A total of 380 employers in Pekanbaru City, Riau Province, were selected as the participants. The results showed that SME performance partially mediates the relationship between entrepreneur competence and satisfaction. This is because the direct effect between SMEs' performance and ES is still significant. The implication of this study implies that there is a need to improve the SMEs' performance to increase their competence and create satisfaction for employers. Moreover, entrepreneurs who are satisfied with their businesses always wish to stay longer and do not give up on it. </p>
MAA: Multi-objective Artificial Algae Algorithm for Workflow Scheduling in Heterogeneous Fog-Cloud Environment
Authors: Shukla Prashant , Pandey Sudhakar 
Published: December 2022

Abstract
Cloud Computing (CC) is the most popular tool of choice for conducting scientific experimentation on Cloud Servers (CDs). It can be even more efficient strategy to use Fog Computing (FC) for allocating and executing operations on Fog Devices (FDs). Complex scientific operations need the effective use of virtual machines (VMs). Scientific workflow scheduling problem is regarded as NP-complete. This problem is constrained by various factors, such as Quality of Service (QoS), interdependence between tasks, user deadlines, etc. There is a very less research available on scientific workflow scheduling in Fog-Cloud Environments (FCE). Classical scheduling techniques, evolutionary optimization algorithms, and other methodologies are the available solution to this problem. In this paper, an efficient meta-heuristic approach named Multi-objective Artificial Algae (MAA) algorithm is presented for scheduling scientific workflows in heterogeneous FCE. In the first phase, the algorithm preprocesses scientific workflow and prepares a tasks list. In order to speed up execution, bottleneck tasks are executed with high priority. The MAA algorithm is used to schedule tasks in the following stage to reduce execution times, energy consumption and costs. In order to effectively use fog resources, the algorithm also utilizes the weighted sum based objective function. The suggested approach is evaluated using five benchmark scientific workflows. To verify the performance, the proposed algorithm's results are compared to those of conventional and specialized scheduling algorithms. In comparison to previous methodologies, the results demonstrate significant improvements in execution time, energy consumption and total cost without any trade-offs.

Authors: Hussen Abduselam Kemal 
Published: December 2022

Abstract
Beggary is not welcomed in our society and in many religious teachings. However, many people, including those who are physically healthy, are earning a living from begging. The purpose of this study was to assess the reasons forcing physically healthy adult beggars to lead life through begging, strategies they employed and mental wellbeing. Data were collected from 100 participants selected through purposive and convenience sampling techniques by the help of interview, FGD and Mental Health Continuum Scale. The findings revealed that invitation, poverty, and unemployment were among the reasons accounting for begging. The results of the quantitative data revealed that the mean score of mental wellbeing of physically healthy beggars (56.6) was found above average (35); indicating that the participants were mentally healthy too. The analysis of the t-test shows that there was significant difference between addicted and non-addicted adult beggars in mental wellbeing; t(df = 36) = 6.8, p < .01).The researcher recommends that to minimize or ultimately stop the behavior, reasons accounting for begging need to be emphasized and improved.
Export and Economic Growth Dynamics in Uganda

Published: December 2022

Abstract
This article examines the relationship between economic growth and exports in Uganda using annual time series data and in the ARDL framework. The study provides evidence on the short and long run relationship between economic growth and exports and tests the export-growth-led hypothesis for Uganda. Our results reveal that exports significantly promote both short-run and long run economic growth in Uganda within the study period. Secondly, the results adjustment coefficient is negative and statistically significant, implying that there is a long-run relationship between exports and economic growth. Also, the adjustment coefficient indicates that the speed of adjustment to equilibrium is about 86% in case of any shock to the economy. In addition, our results show that foreign exchange rate, inflation and trade openness have a significant and negative effect on economic growth while private credit and capital formation have a positive and significant effect on long-run economic growth rate in Uganda. On the other hand, gross capital formation, private sector credit and exchange rate growth have a positive and significant effect on economic growth rate in Uganda in the short run. The findings of this study suggest that there is need for increased government commitment to boost production and quality of exports in order to exploit the untapped export potentials of the country. Secondly, government needs to put in place measures to ensure efficient utilization of external resources and a clear road map for trade openness. Finally, government should also put in place sound investment policies like ease of access to affordable credit plus stable macroeconomic conditions in form of low inflation and a stable exchange rate in order to stimulate economic growth that will further boast the country’s overall growth and development potentials.

Abstract
Weed control in crop cultivations is a sustainable approach that can contribute to a reduction in pesticide use as part of an integrated pest management strategy. This study was conducted to evaluate the bio-herbicidal potential of shoot system of Ononis vaginalis Vahl. on Rumex dentatus L.; a major pest of broad bean (Vicia faba L.). General phytochemical screening of O. vaginalis showed an abundant production of allelochemicals as secondary metabolites which may play a role as natural herbicides. Germination and growth bioassays were conducted to investigate the effect of aqueous and crude powder of the donor species on some germination and growth parameters. Results showed that there was no significant effect of low concentrations on seed germination of V. faba in both pure and mixed cultures on contrarily to those recorded for R. dentatus; gradual decrease with increasing O. vaginalis concentrations in both cultures. On the other hand, total phenolics in V. faba shoot and root showed an increase under different treatments except in high concentration treatment. While in R. dentatus, total phenolics and flavonoids fractions in root of V. faba were decreased in response to different concentration treatments. On the other hand, flavonoids increase in shoots of R. dentatus, while decreasing in roots in mixed culture under high concentration treatments. In conclusion, the study confirmed the integration of O. vaginalis in existing weed control management systems. O. vaginalis could be further tested for suppression of weed growth under field conditions.
The Microscopic Foundations of Solid Compositions in Planetary Systems
Authors: Wang Lile , Yang Haifeng , Xu Shenzhen 
Published: December 2022

Abstract

Dust grains in the interstellar media and protoplanetary disks have roughly equal abundances in carbon and silicates. When coagulating and growing into larger astronomical objects, theories bridging grains to the growth products struggle to quantitatively explain the <10−2 carbon to silicon ratio in rocky planets. Here we propose a new paradigm that self-consistently establishes the microscopic foundations for dust evolution theories by integrating them with ab initio computational chemistry. CO and H2O, the most substantial astrophysical molecules that can be “glues” in grain growths, exhibit drastically weaker adsorption on carbonaceous grains than silicates. This effect inhibits the inclusion of carbon in planetesimals by the desorption of these “glue molecules” from warm carbonaceous grains close to the host star (≲ 8 AU for a solar-system-equivalent), giving rise to the high Si-C abundance ratios in warm regions. The same mechanism semi-quantitatively yields the trend of increasing carbon abundances in the outer parts of our Solar system and likely generic planetary systems.

Published: December 2022

Abstract
Background. The gaps at the margins of restorative composite resin can increase as the carious process occurs underneath the materials, causing further demineralization along the tooth cavity wall. The aim of this study was to evaluate the effects of restorative resin composite containing hydrated calcium silicate (hCS) filler on enamel protection against demineralization by simulating microleakage between the test material and teeth in a cariogenic environment.
Methods. The experimental resin composites were composed of 70 wt% filler, which was mixed with a glass filler and hCS in a weight ratio of 70.0% glass (hCS 0), 17.5% hCS + 52.5% glass (hCS 17.5), 35.0% hCS + 35.0% glass (hCS 35.0), and 52.5% hCS + 17.5% glass (hCS 52.5). A light-cured experimental resin composite disk was positioned over a polished bovine enamel disk, separated by a 30-µm gap, and immersed in artificial saliva with pH 4.0 for 15, 30, and 60 days. After the immersion period, the enamel disk was separated from the resin composite disk and evaluated using a microhardness tester, atomic force microscopy, and polarized light microscopy. The opposing sides of the enamel and resin composite disks were observed using scanning electron microscopy/energy dispersive X-ray spectrometry (SEM/EDS).
Results. The enamel surface showed a significant increase in microhardness, decrease in roughness, and remineralization layer as the proportion of hCS increased (P < 0.05). In the SEM image, enamel surface with hCS 35.0 and 52.5 after all experimental immersion periods showed a pattern similar to that of a sound tooth.
Conclusions. The results demonstrated that increasing the hCS filler level significantly increased the prevention effect of enamel demineralization compared to restorative resin composites containing conventional dental glass filler. Despite some microleakage exposed to a cariogenic environment, these novel composites may be promising dental biomaterials for protecting teeth against demineralization and preventing secondary caries around the restorations.

Abstract
Objective: To assess the effect of Pulse indicator continuous cardiac output (PiCCO) compared to traditional hemodynamic monitoring in patients with acute respiratory distress syndrome (ARDS).
Methods: We conducted a meta-analysis of randomized controlled trials (RCTs) published from Jan. 1, 2012 to Oct. 1, 2022 comparing PiCCO to traditional hemodynamic monitoring in patients with ARDS.
Results: We identified 9 RCTs and combined data from 747 patients, including 369 patients in the experimental group and 378 patients in the control group. Compared to the control group, patients in experimental group have shorter mechanical ventilation time (MD: -3.91, 95% CI [-4.91, -2.92], P＜0.00001, random eﬀects model) and length of ICU stay (MD: -5.23, 95% CI [-6.64, -3.82], P＜0.00001, random eﬀects model). 28-day mortality were observed lower in patients monitored by PiCCO compared to that in control group (RR: 0.53, 95% CI [0.39, 0.73], P=0.0001, fixed eﬀects model).
Conclusions: PiCCO monitoring can effectively reduce the 28-day mortality of ARDS patients, shorten the duration of mechanical ventilation and ICU stay, and has a positive significance for improving the prognosis of ARDS patients.

Published: December 2022

Abstract
Pathophysiological mechanisms of liver dysfunction in Turner syndrome (TS) are not well understood. We examined systemic inflammatory indices (neutrophil-lymphocyte-ratio, NLR; AST-to-platelet ratio, APRI; AST-to-lymphocyte ratio, ALRI; and GGT to platelet ratio, GPR) in patients with TS and their potential application in describing the endocrine and metabolic abnormalities of these subjects.
We performed a retrospective analysis of medical records of 79 TS patients (mean age 32.5 years ± 9.2 SD) followed in the University Hospital of Nancy. Using matched-pair analyses based on age and BMI, we compared 66 TS patients (25.6 ± 7.3 years; BMI 25.9 ± 6.3 kg/m2) to 66 healthy controls (24.7 ± 6.8 years; BMI 26.0 ± 6.7 kg/m2).
Liver abnormalities were present in 54% of the TS subjects. In this subgroup of patients with hepatic abnormalities, inflammatory indices (NLR, APRI, ALRI, GPR) were significantly higher than that observed in TS patients with normal liver function. In the matched-pair analyses, indices APRI, ALRI, and GPR were higher in TS patients than in healthy controls. The results of the logistic regression revealed significant associations between a diagnosis of TS and APRI, ALRI, GPR, liver dysfunction, low bone mineral density, and hypothyroidism.
In conclusion, systemic inflammatory indices NLR, APRI, ALRI and GPR are significantly associated with liver dysfunction in TS. These observations increase our understanding regarding the pathophysiological mechanisms of liver dysfunction in TS. Larger prospective studies are needed to confirm our findings and to explore a prognostic value of inflammatory indices and their potential utility for clinical practice.

Published: December 2022

Abstract
Background: Ischemic stroke (IS) is a heterogeneous condition with varied mechanisms. Some patients have more than one stroke mechanism underlying the incident stroke. This study aimed to examine the association of dual stroke mechanisms among ischemic stroke patients with risk factors and clinical outcomes.
Methods: Case records of adult patients with IS diagnosed using TOAST criteria in a University Stroke-Registry were reviewed for presence of dual IS mechanisms- viz. combinations involving small vessel disease(SVD), cardio-embolism(CE), or large artery atherosclerosis(LA). Outcomes were classified as good (modified Rankin Score=0-3) or poor (4-6). Univariate and multivariate methods of analysis were used.
Results: Among 1220 patients with IS (age: 64+13 years; M:F::63%:37%), 177(14.5%) had an additional mechanism of stroke. SVD(51%) was the most common second mechanism, while CE(23%) and LA stroke(25%) were similar in frequency. On univariate analysis, patients with dual stroke mechanisms were significantly older(p<0.001), had higher frequency of conventional risk factors (p<0.007), abnormal brain MRI(p=0.004) and worse outcomes(p=0.058). On logistic regression analysis, poor outcomes at hospital discharge or 12 month follow-up were independently associated with: older age(p=0.007); female gender(p=0.017); poor sensorium(p<0.001); and type of primary stroke(p<0.001).
Conclusions: Up to one in seven patients with ischemic stroke may have an additional mechanism of stroke. Such patients are likely older, with poorly controlled risk factors, worse sensorium and possible worse outcomes. Small vessel disease is the most common additional stroke mechanism. Studies to explore the influence of dual stroke mechanisms on outcomes as well strategies for secondary prevention are indicated.
Synthesis of hierarchical micro-mesoporous ZSM-5 zeolite and its catalytic activity in benzylation of mesitylene
Authors: Krishnamurthy Manikandan , Swaminathan M. 
Published: December 2022

Abstract
Hierarchical micro-mesoporous ZSM-5 (MFI type) zeolite was synthesized by using corn plant stem pith powder from agricultural waste as hard template under simple hydrothermal method. The additional porosity generated using this pith powder into the zeolites precursor gel yielded hierarchical micro-mesoporous ZSM-5 zeolite (C-ZSM-5). Conventional microporous ZSM-5 (ConvZSM-5) was prepared. The prepared C-ZSM-5 zeolite exhibited 89% conversion, much greater than ConvZSM-5 (33%). Selectivity in the formation of 2-Benzyl-1, 3,5-trimethylbenzene, by benzylation with C-ZSM-5 (70%) is more than two times than ConvZSM-5 (33%). This benzylation can be used as a test reaction to evidence the hierarchical micro-mesoporous nature of the material. The product was further confirmed by 1HNMR and 13CNMR.The hierarchical pores present in the catalyst further improved the stability of the zeolites.

Abstract
Treacher Collins syndrome (TCS, MIM #154500) is a severe congenital disorder implicated in particular dysplasia of the craniofacial bones, accompanied by downslanting palpebral fissures, lower eyelid colobomas, microtia, or other craniofacial malformations. However, the underlying pathogenic mutations in TCS are still unknown, and elucidating these is of primary importance for TCS researchers. We collected samples from a Chinese TCS family, including the proband and two parents. Sequencing, genotyping, and in silico analyses were employed to detect pathogenic mutations in the pedigree. In the proband, a de novo frameshift mutation of TCOF1 c.1562_1574del (p.A521fs) was identified as a pathogenic candidate, while the parents showed no mutations. The frameshift mutation results in TCOF1 truncation and damages the central repeat domain, which is the binding site for transcriptional factors. In conclusion, we identified a novel mutation TCOF1 c.1562_1574del, which is likely a pathogenic mutation for TCS, thereby expanding the mutation spectrum of TCS.

Abstract
Using the example of the city of São Paulo (Brazil), in this paper, we analyze the temporal relation between human mobility and meteorological variables with the number of infected individuals by the COVID-19 disease. For the temporal relation, we use the significant values of distance correlation t0(DC), which is a recently proposed quantity capable of detecting nonlinear correlations between time series. The whole period analyzed goes from Feb 26th to Jun 28th, 2020. Fewer movements in Recreation and Transit Stations and the increase of the maximal temperature, {have strong correlations with the number of newly infected cases occurring 17 days after. Furthermore, more significant changes in Grocery and Pharmacy, Parks and Recreation, and sudden changes in the maximal pressure occurring at 10 and 11 days before the disease's beginning are also correlated with it. Scanning the whole period of the data, not only the early stage of the disease, we observe that changes in human mobility primarily affect the disease for 0 to 19 days after. In other words, our results demonstrate the crucial role of the Municipal Decree declaring an emergency in the city to influence the number of infected individuals.

Published: December 2022

Abstract
The medical internet of things (MIoTs) is essential for enhancing people's protection, care, and health. Health-related criteria for patients can be remotely tracked and transferred to medical data centers via cloud storage, saving them the trip to the hospital. Additionally, the volume of data processed by MIoTs devices is growing exponentially. Due to the increased revelation of sensitive information, there are many unresolved issues about data security and privacy gathered through MIoTs devices. The requirement to apply machine learning algorithms to massive industrial data is developing as quickly as categorization methods themselves. We offer an Entangled Fuzzy Logic based Quantum Key Distribution (EFL-QKD) for data protection to improve and assess the degree of security such breaches, data integrity, etc. in order to safely store and handle this information in the cloud. Results show that the proposed method enhancing the level of security to the cloud more than 99%, the works remarkably well.

Published: December 2022

Abstract
Metal-organic framework materials(ZIF-67) were loaded on Sodium alginate/polyvinyl(PVA/SA) hydrogel by in situ growth method for adsorption of heavy metal Cu (II). The structure of hydrogels composited with MOFs and polymers was designed to improve the poor mechanical properties of natural polymer gel materials and the inconvenience of powdered MOFs materials in practical applications. Synthesized hydrogel spheres were characterized by FT-IR, SEM, XRD, XPS, etc. The adsorption results showed that the optimum adsorption process of Cu (II) pH was 5.0. The adsorption kinetics and isotherm suggest that the adsorption process follows the Freundlich isotherm and the pseudo-second-order models. The experimental maximum adsorption capacity was 128.4 mg/g, 3.3 times and 1.8 times higher than ordinary SA and PVA/SA hydrogel spheres. The selectively experimental results show that PVA/SA@ZIF-67 exhibits better adsorption performance (especially for ion Cu(II), Pb(II) ) and it also indicates that PVA/SA@ZIF-67 has application potential when applied in some specific fields of wastewater treatment. More importantly, PVA/SA@ZIF-67 exhibited exceptional mechanical stability and showed excellent recycling capability in the cyclic adsorption process.
