Long-Range Periodicity of S/Au(111) Structures at Low and Intermediate Coverages

Through a systematic analysis based on DFT calculations, we have studied the adsorption of S atoms on Au(111) at low and intermediate coverages (θ ≤ 1/3). Our calculations predict ground state structures characterized by two periodicities: (5 × 5) and (√3 × √3)R30°. In line with experiments, the (5 × 5) periodicity seems to dominate in a much larger coverage range than the (√3 × √3)R30° one, which should be only observable in a narrow coverage window close to 1/3. In addition, our results unambiguously reveal the crucial role of S-induced substrate relaxation. Using a first-principles parametrized lattice-gas Hamiltonian approach, we determine lateral interactions between S atoms which allow us to provide a sound explanation for the relative stability of ground state structures.
Commutators of the B-maximal operator and B-maximal commutators

In this paper we consider the commutator of the B-maximal operator and the B-maximal commutator associated with the Laplace-Bessel differential operator. The boundedness of the commutator of the B-maximal operator with BMO symbols on weighted Lebesque space and weak-type inequality for the commutator of the B-maximal operator are proved.
Integrated Multimodel Control of Nonlinear Systems Based on Gap Metric and Stability Margin

To avoid linear model redundancy and simplify the structure of a multimodel controller, two general integrated multimodel control design frameworks, which integrate the multimodel decomposition and the multimodel combination of a nonlinear system, are proposed based on the gap metric and stability margin criteria. One method uses the maximum stability margin (which is comparatively controller-independent) while the other uses the actual stability margin of a given controller design. For a prescribed linear control algorithm for local controller design, a smaller and better linear model bank that provides necessary information for multimodel controller design is obtained systematically without model redundancy. Besides, the local robust stability and performance of the system in each subregion can be achieved by the corresponding local controller. Many linear control techniques can be used in the proposed design frameworks, and H∞ control algorithm is employed as an example and applied to two benchmark non.
Incidence of malignant mixed ovarian germ cell tumours in a tertiary care hospital: A five year retrospective study

Malignant mixed ovarian germ cell tumours, typically present in the teenage years, are a rare group of rapidly growing and highly aggressive neoplasms that are derived from the primitive germ cells of the embryonal gonad representing 5% of all malignant ovarian germ cell tumours. The objective of this study was to analyze the incidence of these tumours in our reference hospital and compare the results with those reported in the literature. We analyzed all cases of ovarian tumours during the period from January 2015 to December 2019 and malignant mixed germ cell tumours were selected for analysis. Only 5 cases (9.2%) were histologically diagnosed among 1080 patients with ovarian cancer diagnosis; the mean age of presentation was 17.4 years, abdominal pain was the most common symptom, fertility preservation surgery was practiced in the majority of cases (n=3/5). According to our findings, the incidence rates, surgical approach and chemotherapy responds are very similar to the rates reported in the Western literature. *Correspondence to: Emilio M Treviño-Salinas.

When Can SMEs Diversify? A Study of Growth Stage Model Analysis

Diversification is considered as one effective tool in expanding the business. However, different finding discovered in Small and Medium Enterprises (SMEs) where diversification is not the main priority even though it will help their growth. This qualitative study utilizes growth stage model as a framework to reveal in which stage SMEs can diversify. Hence, this paper aims to reveal the suitable stage where SMEs can diversify where the sample taken from SMEs in Java Island, Indonesia. The research discover that the opposite of Large Companies (LOs), diversification is not a powerful growth strategy for SMEs. Even though diversification is still a choice for SMEs, it cannot be done especially in the stage 1 (one) and 2 (two) of their growth. In explaining the diversification decision within SMEs, this article applies Threat, Opportunity, Weakness and Strength (TOWS) analysis to gain better understanding whether to diversify or not. Finally, this article provides proposed growth stage model to illustrate the most critical stage a business has to deal.
Comparison of EEG biofeedback and visual search strategies during e-sports play according to skill level

About 83% of the perceptual information humans receive from the outside world comes through the visual domain, making the tracking of visual information important for the superior performance of e-sports players. In addition, it is known that e-sports players’ emotional state during performance affects their results. However, few studies have examined visual search strategies and electroencephalogram (EEG) findings of e-sports players while engaged in e-sports. Therefore, the present study aimed to investigate the characteristics of visual search activity and EEG feedback during first person shooter (FPS) game play, in which the tracking of visual information is important, and to examine the characteristics of different gaming skill levels. Four skilled and five semi-skilled e-sports participants (mean age ± 19.11, SD = 0.99) participated in this study. Gazepoint GP3 (Canada) was used to measure eye movements, and the Sports KANSEI (Littlesoftware Inc., Japan) was used to analyse the emotional state of the participants by using EEG data. The results showed that the skilled e-sports players checked the camera significantly more frequently than the semi-skilled participants. The results of the area of interest (AOI) analysis showed that skilled e-sports players glanced at the friendly team information displayed at the top of the game screen more often than semi-skilled players. Furthermore, it was found that skilled e-sports players had significantly higher average EEG relaxation values during gameplay than semi-skilled players. Thus, the visual search strategy and emotional state while playing e-sports differed according to gaming skill level.
Sex differences in the trajectories of and factors related to extracurricular exercise: A cohort study spanning 13 years

Background Extracurricular exercise (ECE) refers to regular exercise/sports participation in addition to the normal physical exercise education in school among a school-aged population. Rather than general physical activity, ECE is typically deliberately initiated and presents an efficient target for interventions. However, relatively few studies have investigated sex differences in the development of ECE from childhood to emerging adulthood. This study aimed to examine the latent trajectories of ECE from childhood to emerging adulthood across sexes and to identify the associated sex-specific individual (i.e., body mass index, body dissatisfaction, stress, and screen behavior) and parental factors (i.e., parental exercise and parental screen behavior). Methods This study used data from part of the Child and Adolescent Behavior in Long-term Evolution (CABLE) project, which comprised 2,072 fourth graders (aged 9 years) in Northern Taiwan followed from 2001 to 2013. Repeated-measures latent class analysis was used to identify the trajectories of ECE for males and females, respectively. Multinomial logistic regression was further used to identify sex-specific factors related to ECE after controlling for the parental education level, family monthly income, and parental marital status. Results Four trajectories of ECE were identified for males and females. For males, these trajectories were Rarely-to-Never, Often-to-Rarely, Always-to-Never, and Always. For females, these trajectories were Rarely-to-Never, Rarely, Always-to-Rarely, and Always. We observed that the developmental patterns of ECE varied by sex such that there was an earlier decline in the trajectories of ECE in females than in males and that, compared with males, fewer females maintained exercise habits in young adulthood. Furthermore, we found several sex-specific factors related to ECE, namely, stress, BMI, and parental exercise. Body dissatisfaction and individual screen behavior were associated with trajectories of ECE for both sexes. Conclusions We found distinct trajectories of ECE from childhood to emerging adulthood for both sexes. The trajectories of ECE for males and females, however, differ in terms of patterns and associated factors. Our findings suggest that efforts to increase ECE should be initiated early and may be made more effective by considering sex differences.
Magnitude of metabolic syndrome and its components among adult residents of Mekelle city, Northern Ethiopia, community-based cross-sectional study.

Background: Metabolic Syndrome is becoming a big public health problem in developing countries like Ethiopia. The risk of dying from NCDs in low and lower-middle-income countries is almost two times that in high-income countries. NCDs account for 42% of deaths in Ethiopia. The trend of deaths due to NCD is increasing over time in Ethiopia. The objective of this study was to assess the magnitude of metabolic syndrome and its components among adult residents of Mekelle city.Method: a community-based cross-sectional study was conducted from July to September 2019 among adults aged 20 years and above in Mekelle city. Around 266 study participants were selected using a simple random sampling technique. Sociodemographic, lifestyle, anthropometric measurements, and blood biochemical tests were performed using WHO stepwise technique. Blood glucose and lipid profiles were determined after overnight fasting. The classification of metabolic syndrome was based on the international diabetic federation criteria. Descriptive statistics and logistic regression analysis were done using SPSS version 24.Result: the prevalence of Metabolic syndrome was 21.8%. Elevated waist circumference was the most prevalent metabolic syndrome component followed by hypertriglyceridemia, with a prevalence of 41.7% and 38.0% respectively. The prevalence of the remaining three components of MetS were also 33.8%, 32.7%, 21.4%, and 14.3% for systolic blood pressure, diastolic blood pressure, fasting blood glucose, and lower high-density lipoprotein cholesterol respectively. Age of 40 years and above, the highest rank of monthly income, blood cholesterol greater than 200mg/dl, waist to height ratio greater than 0.55, and walking at least 10 minutes daily were identified as significant predictors of metabolic syndrome.Conclusion : Adult residents of Mekelle city have a high magnitude of Metabolic syndrome and its components which may aggravate the risk of developing cardiovascular disease. This result emphasizes an urgent need for a public health strategy for preventive, early detection, and management of metabolic syndrome, and its individual components.
Spherical Symmetric Kink-Like Configurations of Spinor and Gravitational Fields

The present research work deals with an extension of a previous work [Exact Soliton-like spherical symmetric solutions of the Heisenberg-Ivanenko type nonlinear spinor field equation in gravitational theory, Journal of Applied Mathematics and Physics, 2020, 8, 1236-1254] to Spherical Symmetric Kink-Like Configurations of Spinor and Gravitational Fields. We have obtained exact kink-like static spherical symmetric solutions to the self-consistent system of spinor and gravitational fields equations. The Einstein’s field equation shave been solved by the Liouville method. The principal difference between kink soliton with antikink soliton has been established. The nonlinear terms in the lagrangian are arbitrary functions F(IS) depending on the invariant IS = S2= ( )2. It is shown that the initial set of the Einstein and spinor field equations have regular solutions with a localized energy density of the spinor field only if m = 0 (m is the mass parameter in the spinor field equations). Equations with polynomial nonlinearities are thoroughly scrutinized. Let us emphasize that the spinor field with polynomial nonlinearities has a regular solutions with localized, positive and alternating energy density and finite total energy. In addition, the total charge and the total spin are also finte. We have also obtained exact solutions to the linear spinor field equations. We remarked that in this case soliton-like solutions are absent. Furthermore, we note that the properties of regular localized solutions depend on the symmetry and the nonlinear terms in the lagrangian of the self-consistent system of gravitational and spinor fields.
Dimensions of CH4-Jet Flame in Hot O2/CO2 Coflow

The present study has numerically simulated the oxy-fuel combustion of a methane (CH4) jet in hot coflow (JHC). The main objective is to investigate the influences of the oxygen (O2) molar fraction (XO2*), temperature (Tcof*) and velocity (vcof*) of the O2/CO2 coflow on dimensions of the JHC reaction zone or flame. The simulations use the model of eddy dissipation concept (EDC) with the detailed chemical mechanism described by GRI-Mech 3.0. To validate the modeling, several air-fuel JHC flames are predicted under the same conditions of the work of Dally et al. [Proc. Combust. Inst.2002, 29, 1147–1154]; the predictions match well with the measurements. Results suggest that, as either XO2* or vcof* decrease or Tcof* increases, the volume of the JHC reaction zone increases and hence the overall oxidation rate of CH4 decreases. In particular, raising the coflow speed vcof* causes the flame to be significantly thinner but only slightly longer. It is also demonstrated that the oxy-fuel reaction zone is larger, .
Exploring the relationship between menopausal symptoms, personality, and depressive symptoms in postmenopausal women

Background A quick look at the results of research studies in the existing literature indicates that depression in postmenopausal women can greatly affect their function and self-esteem. The aim of the present study was to explore the potential relationships between menopausal symptoms, sleep quality, hot flash, and depressive symptoms in postmenopausal women.Methods A cross-sectional study was designed with 150 healthy postmenopausal women (45–60 years of age) who had referred to the menopausal clinic in Babol. The participants completed the following instruments throughout the study: the Beck Depression Inventory for depressive symptoms, the Modified Blatt-Kupperman Menopausal Index for measuring menopausal symptoms, and the NEO-FFI for identifying the personality traits.Results After controlling all the covariates, high depressive symptoms were found to be associated with moderate/ sever menopausal symptoms, poor sleep quality, and the average and high level of neuroticism. The results also demonstrated that the risk of depressive symptoms was lower in menopausal women with high level extroversion, high level agreeableness, and the average and high level of conscientiousness.Conclusions The findings of the present study indicated that personality traits, menopausal symptoms, and poor sleep quality in particular can partially account for depression in Iranian menopausal women.
Exclusive Characteristics and Management, Status and Performance Parameters of Balochi Sheep

| The current study was conducted to know about the management practices, production system, and parameters of Balochi sheep. This sheep is highly adaptive to agro-climatic conditions of Balochistan. Data of Balochi sheep (n=7049) from fifteen villages of three districts were collected regarding nutrition, administration practices, physical condition, and productive concert through performa and individual perceptions. Body weight and biometric measurements were recorded regularly for rams (n=680) and ewes (n=840) from three districts namely Kalat, Mastung, Quetta and from Multi-Purpose Sheep Research Station Yetabad, Loralai (MSRSYL). Sexual dimorphism is evident for several traits like it has significant effect (p<0.05) on weight, body length, heart girth, wither height while tail length was found to be non-significantly different between sexes (p>0.05). Balochi sheep husbandry is favorite because of its adaptability, great survival rate and growth performance, however returns from sheep production are marginal and low-cost production is still a challenge.

Characterization of highly waste loaded glass for HLW

The possibility of highly waste loaded borosilicate glasses up to 65 wt% were investigated for HLW. In the case the waste was loaded at a content higher than 45 wt%, apatite crystal was identified in the glasses. Adding above 2.5 wt% of MoO{sub 3}, yellow phase was observed in the 45 wt% waste glass. In the case the composition of actual waste was simulated, waste (25--45 wt%) glasses were characterized. Chemical durability of 45 wt% waste glass was equivalent to that of 25 wt% waste glass under the condition of Na{sub 2}O content lower than 12 wt%. Rheological behavior of 45 wt% waste glass was equivalent to that of 25 wt% waste glass in the range of melting temperature. Electrical resistivity of 45 wt% waste glass were a little lower than that of 25 wt% waste glass and it depended on the noble metal content. The Time-Temperature-Transformation (T-T-T) diagram and the leach rate of heat treated glass indicated a good thermal stability of highly waste loaded glass below the glass transition temperature. Possibility of high waste loading up to 45 wt% was elucidated.
Yield, water use and water productivity of drip-irrigated cucumber in response to irrigation depths and intervals in Kaduna, Nigeria

A study was carried out at the research farm of the Federal College of Forestry Mechanization, Afaka, Kaduna, Nigeria, to determine the effect of irrigation depths and intervals on the yield, crop water use and water productivity of drip-irrigated cucumber (market-more variety) in two irrigation seasons (2016/17 and 2017/18). Irrigation was scheduled using the reference evaporation data obtained from pan evaporation measurements taken within the experimental periods. The results showed a significant difference in both seasonal crop evapotranspiration and yield at 5% level of significance in both seasons. The highest yields (21 t/ha and 20.3 t/ha) were obtained from the treatments with 100 ETo, irrigated daily (T1), while the lowest (15.5 t/ha and 16.5 t/ha) were obtained from the treatments with 60% ETo, irrigated every four days (T9). The highest water productivities were obtained from the treatments with 60% ETo, irrigated daily (T7), while the lowest were obtained from the treatments with 100% ETo, irrigated every four days (T3), implying a better yield effect due to light high frequent irrigation than deep low frequent irrigation. The marginal difference in yield due to the marginal difference in water applied in T1 and T7 is 3.7 t/ha. It is concluded that full irrigation produced higher yield than deficit irrigation but with lower crop water productivity. http://dx.doi. org/10.4314/njt.v39i2. 33
EST-SSR markers identification based on RNA-sequencing and application in Schisandra chinensis

Background: Schisandra chinensis, a climbing woody vine, is the best-known and representative genus of the Schisandraceae family which is an important plant in Chinese herbal medicine; however, the application of molecular breeding is restricted by the few genetic markers for this species. Results: In this study, we performed transcriptome sequencing of S. chinensis using the Illumina HiSeq platform to establish a library of expressed sequence tag-simple sequence repeat (EST-SSR) markers. A total of 59,786 unigenes were obtained and 6254 putative SSR sites were detected with a frequency of 10.46%. The predominant type of repeat motif was dinucleotide (35.71%), followed by trinucleotide (13.22%), hexanucleotide (0.50%), tetranucleotide (0.06%), and pentanucleotide (0.22%). We randomly selected 50 EST-SSR primer pairs and used 14 of these for genetic diversity analysis in 42 S. chinensis genotypes. All 42 accessions were successfully identified and formed four major clusters, indicating that the SSR markers can be used for genetic diversity analysis and genetic linkage map construction. In addition, using the polymorphic bands associated with 10 markers as DNA fingerprints, we generated a manual cultivar identification diagram that can distinguish between the 42 accessions, with different individuals identifiable based on polymorphic band patterns. Conclusion: S. chinensis transcriptome data is an effective resource for developing SSR markers. These results can provide a basis for the identification of S. chinensis accessions and construction of genetic linkage maps as part of future selective breeding and conservation efforts for this valuable plant.
