A $SU(2)$ Generalized Gauge Field Model With Higgs Mechanism

By means of the non-commutative differential geometry, we construct an $SU(2)$ generalized gauge field model. It is of $SU(2) \times \pi_4(SU(2))$ gauge invariance. We show that this model not only includes the Higgs field automatically on the equal footing with ordinary Yang-Mills gauge potentials but also is stable against quantum correlation.
The Relationship Between Regulatory Requirements Reviews, Compliance Benefits and Costs: Evidence from Selected Commercial Banks in Tanzania

The Central Bank of Tanzania (BoT) has undergone various bank regulations reviews at different periods of time including 2008 and 2014 reviews. After the reviews some banks have shown low compliances, collapsed and merged while others have shown high compliances and greater performance. This study therefore, intended to assess how commercial banks in Tanzania benefits from complying with new regulatory requirements and to determine to what extent does compliance costs affects banks performance. The study employed an exploratory research design using the sample size of 24 commercial banks selected from Dar es Salaam headquarters; however, only 13 key informants were successfully reached. Primary data were collected from compliance and risk management managers using interview guide. Thematic analysis was used for data analysis and findings from the study show that most banks have well benefited with the new regulatory requirements in terms of increase in profit, expansion of more branches, ATMs and increase in number of customers. Considering the compliance costs; findings show that to some extent some new regulatory requirements reviews have increased operating costs to most banks. The study recommends that banks should carefully design strategies which will help them to control NPL, manage and increase more capital and liquidity requirements. To the regulator the study recommends that; BoT should think of reviewing liquidity requirements and cash reserve ratio which seem to be too high and costly for most banks to afford. The BoT can also introduce separate capital adequacy requirements as per bank size.
A “Wake-Up Call” for EFL Students: Exploring the Metacognitive Learning Strategy in the Professional Listening Course

Compared to the cognitive strategies to solve students’ problems in English listening, studies on metacognitive strategies seem to be underexplored in Eastern Indonesian context. In order to contribute to this research gap, this study conducted an investigation on university students' awareness of metacognitive strategies. This mixed-method study used quantitative data from a questionnaire adopted from the Metacognitive Awareness Listening Questionnaire (MALQ). 178 English Education students (19-21 years old) at Pattimura University completed the questionnaire, and eight students were randomly selected to be interviewed to obtain qualitative data regarding their individual metacognitive strategies for planning, monitoring and evaluating their listening activities. The findings reveal more than 60% of the participants agree that they have a plan for their listening activities, can maintain focus during the activities, and evaluate how they performed. Qualitative data supported that the students do have a plan and monitor their learning process, as they can provide specific strategies of how they plan (e.g., taking notes, making sure that the room is suitable for listening tasks) and monitor (e.g., paying attention to keywords, using context to decipher audio’s meaning if they encounter unfamiliar words) their learning process. However, the students seem to be unable to explain or define precisely what metacognitive strategy is, indicating their lack of learning the self-reflection process. These results demonstrated a need for more explicit instruction of metacognitive strategies to improve the students’ learning process, which will be especially beneficial for the university's uniquely high-stakes course of Professional Listening.
Norepinephrine, beyond the Synapse: Coordinating Epigenetic Codes for Memory

The noradrenergic system is implicated in neuropathologies contributing to major disorders of the memory, including post-traumatic stress disorder and Alzheimer’s disease. Determining the impact of norepinephrine on cellular function and plasticity is thus essential for making inroads into our understanding of these brain conditions, while expanding our capacity for treating them. Norepinephrine is a neuromodulator within the mammalian central nervous system which plays important roles in cognition and associated synaptic plasticity. Specifically, norepinephrine regulates the formation of memory through the stimulation of β-ARs, increasing the dynamic range of synaptic modifiability. The mechanisms through which NE influences neural circuit function have been extended to the level of the epigenome. This review focuses on recent insights into how the noradrenergic recruitment of epigenetic modifications, including DNA methylation and post-translational modification of histones, contribute to homo- and heterosynaptic plasticity. These advances will be placed in the context of synaptic changes associated with memory formation and linked to brain disorders and neurotherapeutic applications.
Identification of Potential New Aedes aegypti Juvenile Hormone Inhibitors from N-Acyl Piperidine Derivatives: A Bioinformatics Approach

Aedes aegypti mosquitoes transmit several human pathogens that cause millions of deaths worldwide, mainly in Latin America. The indiscriminate use of insecticides has resulted in the development of species resistance to some such compounds. Piperidine, a natural alkaloid isolated from Piper nigrum, has been used as a hit compound due to its larvicidal activity against Aedes aegypti. In the present study, piperidine derivatives were studied through in silico methods: pharmacophoric evaluation (PharmaGist), pharmacophoric virtual screening (Pharmit), ADME/Tox prediction (Preadmet/Derek 10.0®), docking calculations (AutoDock 4.2) and molecular dynamics (MD) simulation on GROMACS-5.1. 4. MP-416 and MP-073 molecules exhibiting ΔG binding (MMPBSA −265.95 ± 1.32 kJ/mol and −124.412 ± 1.08 kJ/mol, respectively) and comparable to holo (ΔG binding = −216.21 ± 0.97) and pyriproxyfen (a well-known larvicidal, ΔG binding= −435.95 ± 2.06 kJ/mol). Considering future in vivo assays, we elaborated the theoretical synthetic route and made predictions of the synthetic accessibility (SA) (SwissADME), lipophilicity and water solubility (SwissADME) of the promising compounds identified in the present study. Our in silico results show that MP-416 and MP-073 molecules could be potent insecticides against the Aedes aegypti mosquitoes.

Conclusion: Findings provided information on the poor quality of the well water, which will be useful in groundwater treatment strategies and policy formulation by appropriate groundwater source protection bodies.
Convergent Expansions for Solutions of Linear Ordinary Differential Equations Having a Simple Pole, with an Application to Associated Legendre Functions

Second‐order linear ordinary differential equations with a large parameter u are examined. Asymptotic expansions involving modified Bessel functions are applicable for the case where the coefficient function of the large parameter has a simple pole. In this paper, we examine such equations in the complex plane, and convert the asymptotic expansions into uniformly convergent series, where u appears in an inverse factorial, rather than an inverse power. Under certain mild conditions, the region of convergence containing the simple pole is unbounded. The theory is applied to obtain exact connection formulas for general solutions of the equation, and also, in a special case, to obtain convergent expansions for associated Legendre functions of complex argument and large degree.

Calculation of THz frequency conversion by HNDFWM in /spl lambda//4-shifted DFB lasers

We have developed a theoretical model to study the highly nondegenerate four wave mixing (HNDFWM) in /spl lambda//4-shifted DFB laser diodes. Frequency detuning up to 4 THz between the self-generated pump wave and the injected probe wave is envisaged. Wavelength-converted signal can be generated in a comparable bandwidth. Our results are in very good agreement with recent experiment.
Stability and performance analysis of hybrid braceless semisubmersible platform installed in real seas

The possibility of combining Floating Offshore Wind Turbines (FOWT) and Wave Energy Converters (WEC) on one single platform is proposed here. To understand how the presence of two flap type WEC influences the platforms’ stabilities and subsequently turbine’s performances, an extensive study is carried out in real seas under two imperative states of turbine viz. operational & survival state. Accordingly, an integrated aero-hydro-elastic numerical model is developed with the help of multiple software, and finally coupled dynamic analysis is carried out in Orcaflex. After performing the analysis, it shows that wave and wind have synchronizing effects on the system’s stability and subsequently decide the turbine’s power. It is observed that the presence of WEC exhibits lesser platform responses with more turbine power from the base platform. Finally, the size and layout of the flap type WEC along with the flexibility of the supporting arm are compared and recommended the suitable.

Global well-posedness and scattering for the defocusing, $L^{2}$-critical nonlinear Schrödinger equation when $d =3$

In this paper we prove that the defocusing, $d$-dimensional mass critical nonlinear Schr{\"o}dinger initial value problem is globally well-posed and scattering for $u_{0} \in L^{2}(\mathbf{R}^{d})$ and $d \geq 3$. To do this, we will prove a frequency localized interaction Morawetz estimate similar to the estimate made in [10]. Since we are considering an $L^{2}$ - critical initial value problem we will localize to low frequencies.
Is Innovation a Risky Business? A Comparative Analysis in High-Tech and Traditional Industries in Poland

A high level of innovativeness and technology complexity is most often associated with a faster and more dynamic pace of economic development. In turn, it enables enterprises to achieve better financial results and strengthen their competitive advantage. Despite these potential benefits, in practice, innovation is also associated with the need to take up new challenges, which may be accompanied by a higher risk. The main goal of the research is a comparative analysis of the relationship between innovation and the risk of running a business in traditional and high-tech industries exemplified by the Polish economy. The authors assess the risk in 44 enterprises in the years 2010–2020 based on the proprietary evaluation model that uses the variation of financial parameters associated with innovativeness. The obtained results indicate a higher level of risk in the high-tech group with more complex and modern technologies, in particular in the pharmaceutical and computer games sectors. In the group of traditional enterprises, the risk in the analysed sectors is more diversified, and it is much higher in manufacturing enterprises than in services and trade. The empirical and quite extensive nature of the research allows for a practical assessment of the direction and strength of the relationship between innovation, risk and technology complexity.
Does Board Size Mediate the Relationship Between Accounting Information and Stock Market Return? Evidence From Listed Financial Firms in Ghana

The study examined the relationship between accounting information and stock market returns of listed financial entities on the Ghana Stock Exchange using board size as a mediating variable. The population of the study was 13 listed financial entities from 2007-2019 with 169 firm-year observations. This study applied a panel regression model that takes unobserved individual heterogeneity and distributional heterogeneity into consideration. In addition, the study employed cross-section dependence test; Levin-Lin-Chu (LLC), ImPesaran, Pesaran, Kao, and Larsson cointegration test; Fully Modified Ordinary Least Square (FMOLS) and Dynamic Ordinary Least Square (DOLS). The results of the unit root test showed that all the variables were integrated at first difference. Moreover, the results of cointegration test revealed that accounting information variables were cointegrated in the long run. The result of FMOLS and DOLS revealed that all the accounting information variables with the exception of operating cash flow per share (OCFPS) and net tangible assets (NTA) have a direct insignificant relationship with the stock market return of listed financial entities. The study revealed that board size strengthens the relationship between OCFPS and NTA, and stock market return at 5% significant level under FMOLS and DOLS of listed financial entities.
The parallel multigrid and domain decomposition methods for an elliptic problem on a hexagonal domain with structured triangular meshes

This article is a technical report on the HLST project “Parallel Multigrid on Triangles” (MGTRI) submitted by B. Scott for developing a fast parallel solver for the gyrokinetic simulation on a massively parallel computer. We consider a second order elliptic partial differential equation on a hexagonal domain with structured triangular meshes. We implemented a parallel matrix-vector multiplication algorithm tailored to the structured triangular meshes on the hexagonal domain. The algorithm achieved very good strong and weak scaling properties. In addition, we investigated and implemented a parallel multigrid method and two non-overlapping domain decomposition methods, namely the FETI-DP and BDDC.
Role of Occupation in Shaping Cancer Disparities

Simple Summary The investigation of cancer disparities is of major importance. In this paper, we address this issue through the occupational point of view, trying to capture how work and its related factors impact on cancer inequalities. The data we provide may increase awareness relevant to cancer control, and stimulate further studies aimed at the identification of the occupational determinants of cancer disparities and the quantification of their role. Abstract Cancer occurrence is characterized globally by profound socioeconomic differences. Occupation is a fundamental component of socioeconomic status. In this review, we discuss the role of occupation as a determinant of cancer disparities. First, we address the issue of participation in cancer screening programs based on income, health insurance, occupational status and job title. Second, we review the role of occupation in contributing to disparities by acting as a mediator between cancer and (i) education and (ii) race/ethnicity. Lastly, we analyze data from a multicenter case−control study of lung cancer to calculate the mediating role of occupational exposure to diesel exhaust, silica and welding fumes in the association between education and lung cancer. By addressing the complex paths from occupation to cancer inequalities from multiple points of view, we provide evidence that occupational-related characteristics, such as income, health insurance, unemployment and hazardous exposures impinge on cancer control and outcomes. The increasing awareness of these aspects is fundamental and should lead to public health interventions to avoid inequalities rising from occupational factors.
ARDL Approach to Drivers of Inclusive Growth In India

The call for inclusive growth has been unanimously declared by policymakers across the world. With India’s rapid economic growth rate, Indian policymakers also set its economy on the track of inclusive growth while formulating the 11th Five Year Plan. Despite, India’s fast-growing and vibrant economy, it fails poorly in Human Development Index ranked 131 in 2016. An unfortunate aspect of the current phase of high growth of the Indian economy has been its ‘non-inclusive’ nature. The distribution of income has been highly iniquitous. The richest 1% in India cornered 73% of the wealth generated in 2017, presenting a worrying picture of rising income inequality. In this regard, the study attempts to identify the determinants of inclusive growth in India by using annual data from 1981 to 2015. The study employs the autoregressive distributed lag (ARDL) model and the error correction method (ECM) to investigate the long-run and short-run relationship between inclusive growth and its determinants. The bounds test findings confirm the cointegrating relationship among variables. The ARDL estimates suggest that growth in initial income, government expenditure, human development, investment and financial development fosters inclusive growth; while inflation and population growth dampens it. The results also imply that increasing trade openness and foreign direct investment would not be beneficial for India in terms of growth inclusiveness. Based on these findings, the study recommends that the Government of India should take appropriate steps to increase per capita income and social spending with particular attention to macroeconomic stability while they work at improving the quality of population in order to achieve sustainable and robust inclusive growth.

Effect of High-Intensity Strength and Endurance Training in the Form of Small Circuits on Changes in Lipid Levels in Men Aged 35–40 Years

Background: Blood lipid profiles consist of total cholesterol (TC) and its fractions, high-density lipoprotein cholesterol (HDL), low-density lipoprotein cholesterol (LDL), non-high-density lipoprotein cholesterol (non-HDL), and triglycerides (TG). For several decades, studies have examined the effects of various factors on lipid status and its association with the risk of developing arteriosclerosis and cardiovascular disease. The beneficial effects of increased physical activity on cardiovascular health have been demonstrated by appropriate modulation of lipid profiles. For individuals with low physical activity, the literature recommends engaging in various forms of training that can improve physical fitness and resting lipid status. The aim of the study was to examine whether a specific original training program improves lipid profiles to the levels recommended for the male population. Methods: The study involved two equal (n = 15) groups of men (experimental and control groups, aged 35–40 years). The experimental group performed 60-min training sessions for 8 weeks (3 times a week) including a set of strength and endurance exercises. Before and after the training program, blood was drawn from both groups for serum determination of TC, HDL, LDL non-HDL, and TG, and a battery of four field physical performance tests was administered. Results: Statistically significant decreases (TC by 19.3%, TG by 23.7%, LDL by 15%), a non-significant decrease (10% for non-HDL), and no change for HDL were found in the experimental group. Control group showed a statistically significant decrease, by 7.4% for TC. The results confirm the effectiveness of the proposed training in improving health indices. Conclusions: The 8-week training program met the health-related fitness paradigm recommended for physical activity in men aged 35–40 years. After the completion of the program, all the participants expressed their satisfaction from participating in a health-promoting experiment.
