ASYMPTOTIC PROPERTIES IN THE PROBIT-ZERO-INFLATED BINOMIAL REGRESSION MODEL
Authors: Fatimata LO , Bocar BA Demba , Aba DIOP
Published: September 2021

Zero-inflated regression models have had wide application recently and have provenuseful in modeling data with many zeros. Zero-inflated Binomial (ZIB) regression model is an extension of the ordinary binomial distribution that takes into account the excess of zeros. In comparing the probit model to the logistic model, many authors believe that there is little theoretical justification in choosing one formulation over the other in most circumstances involving binary responses. The logit model is considered to be computationally simpler but it is based on a more restrictive assumption of error independence, although many other generalizations have dealt with that assumption as well. By contrast, the probit model assumes that random errors have a multivariate normal distribution. This assumption makes the probit model attractive because the normal distribution provides a good approximation to many other distributions. In this paper, we develop a maximum likelihood estimation procedure for the parameters of a zero-inflated Binomial regression model with probit link function for both component of the model. We establish the existency, consistency and asymptotic normality of the proposed estimator.

Published: September 2021

Polarization tensor (PT) is a classical terminology in fluid mechanics and theory of electricity that can describe geometry in a specific boundary domain with different conductivity contrasts. In this regard, the geometry may appear in a different size, and for easy characterizing, the usage of PT to identify particular objects is crucial. Hence, in this paper, the first order polarization tensor for different types of object with a diverse range of sizes are presented. Here, we used three different geometries: sphere, ellipsoid, and cube, with fixed conductivity for each object. The software Matlab and Netgen Mesh Generator are the essential mathematical tools to aid the computation of the polarization tensor. From the analytical results obtained, the first order PT for sphere and ellipsoid depends on the size of both geometries. On the other hand, the numerical investigation is conducted for the first order PT for cube, since there is no analytical solution for the first order PT related to this geometry, to further verify the scaling property of the first order PT due to the scaling on the size of the original related object. Our results agree with the previous theoretical result that the first order polarization tensor of any geometry will be scaled at a fixed scaling factor according to the scaling on the size of the original geometry.

Published: September 2021

Electricity plays an imperative role in improving the rural or remote community economic growth and quality of life. The pico hydro type Archimedes screw turbine (AST) is considered an independent power plant in rural or remote areas. The advantages of the AST are friendly to aquatic biota, the high and stable efficiency (electrical efficiency of 30% to 49%), and can operate in a run of river conditions. However, although this technology has been studied ± two decades, there is still no theory explaining the relationship between conversion energy, the geometry of screws, and efficiency. Therefore, the development of Archimedes screw focuses on the role of a converter water energy categorized as the environmentally friendly power plant. Thus, this paper aims to describe the future work required for the AST so that the basic principles and empirical theories are found. Based on reviews, the AST design can use Rorres and Muller & Senior analysis, AC generators with a pulley and toothed belt transmission systems, and do not immerse the outflow bucket side in the water. Furthermore, for AST to be better, several studies need to be done such as the method of manufacturing precision screws, the effect bubbles in the bucket and how to avoid them, determination optimum of the head and screw length using the slope angle, and investigation of the ratio of the inlet velocity with the angular velocity of a wheel on performance to avoid overflow leakage due to loading.

Published: September 2021

The article deals with some military consequences of the departure of the United Kingdom of Great Britain and Northern Ireland from the European Union (Brexit). To assess the potential impacts on defence and security of EU, a structured approach involving several methods was used in the analysis, which combines a search of professional publications, factors sensitivity analysis and testing of hypotheses. Based on the analysis, it was evaluated that the departure of the United Kingdom of Great Britain and Northern Ireland from the structures of the European Union will take place without significant impact in the military field and does not pose an immediate threat to the security and defence of EU member states. Nevertheless, in connection with Brexit, there is still a certain risk of negative impacts in this area.
Middle Eastern Proxy Wars Waged on the Background of Civil Wars
Authors: Atanasiu Mirela
Published: September 2021

The paper argues that proxy war is an increasingly often used tool in the Middle East, in the already conflicted territories where international involvement is not only enabled, but also attracted and encouraged by the international law for the purpose of region’s securitization. Thus, the paper’s aim is to increase awareness on the fact that the Middle Eastern countries passing through civil war periods and accepting external actors to deal with their crises do not only become fertile territories for proxy wars, but the intervening actors start pursuing their own interests beyond the host country’s interest in resolving the conflict.

We consider the Cauchy problem for the inhomogeneous nonlinear Schrödinger (INLS) equation

   \begin{document}$ iu_{t} +\Delta u = |x|^{-b} f(u), \;u(0)\in H^{s} (\mathbb R^{n} ), $\end{document}

where \begin{document}$ n\in \mathbb N $\end{document}, \begin{document}$ 0<s<\min \{ n, \; 1+n/2\} $\end{document}, \begin{document}$ 0<b<\min \{ 2, \;n-s, \;1+\frac{n-2s}{2} \} $\end{document} and \begin{document}$ f(u) $\end{document} is a nonlinear function that behaves like \begin{document}$ \lambda |u|^{\sigma } u $\end{document} with \begin{document}$ \sigma>0 $\end{document} and \begin{document}$ \lambda \in \mathbb C $\end{document}. Recently, the authors in [1] proved the local existence of solutions in \begin{document}$ H^{s}(\mathbb R^{n} ) $\end{document} with \begin{document}$ 0\le s<\min \{ n, \; 1+n/2\} $\end{document}. However even though the solution is constructed by a fixed point technique, continuous dependence in the standard sense in \begin{document}$ H^{s}(\mathbb R^{n} ) $\end{document} with \begin{document}$ 0< s<\min \{ n, \; 1+n/2\} $\end{document} doesn't follow from the contraction mapping argument. In this paper, we show that the solution depends continuously on the initial data in the standard sense in \begin{document}$ H^{s}(\mathbb R^{n} ) $\end{document}, i.e. in the sense that the local solution flow is continuous \begin{document}$ H^{s}(\mathbb R^{n} )\to H^{s}(\mathbb R^{n} ) $\end{document}, if \begin{document}$ \sigma $\end{document} satisfies certain assumptions.

Transitions between metastable long-run consumption behaviors in a stochastic peer-driven consumer network
Authors: Jungeilges Jochen , Nilssen Trygve Kastberg , Perevalova Tatyana , Satov Alexander
Published: September 2021

We study behavioral change - as a transition between coexisting attractors - in the context of a stochastic, non-linear consumption model with interdependent agents. Relying on the indirect approach to the analysis of a stochastic dynamic system, and employing a mix of analytical, numerical and graphical techniques, we identify conditions under which such transitions are likely to occur. The stochastic analysis depends crucially on the stochastic sensitivity function technique as it can be applied to the stochastic analoga of closed invariant curves [14], [1]. We find that in a moderate noise environment increased peer influence actually reduces the complexity of observable long-run consumer behavior.
Analysis of the feedback particle filter with diffusion map based approximation of the gain
Authors: Pathiraja Sahani , Stannat Wilhelm
Published: September 2021

Control-type particle filters have been receiving increasing attention over the last decade as a means of obtaining sample based approximations to the sequential Bayesian filtering problem in the nonlinear setting. Here we analyse one such type, namely the feedback particle filter and a recently proposed approximation of the associated gain function based on diffusion maps. The key purpose is to provide analytic insights on the form of the approximate gain, which are of interest in their own right. These are then used to establish a roadmap to obtaining well-posedness and convergence of the finite \begin{document}$ N $\end{document} system to its mean field limit. A number of possible future research directions are also discussed.
Stability of non-linear filter for deterministic dynamics
Authors: Reddy Anugu Sumith , Apte Amit
Published: September 2021

This papers shows that nonlinear filter in the case of deterministic dynamics is stable with respect to the initial conditions under the conditions that observations are sufficiently rich, both in the context of continuous and discrete time filters. Earlier works on the stability of the nonlinear filters are in the context of stochastic dynamics and assume conditions like compact state space or time independent observation model, whereas we prove filter stability for deterministic dynamics with more general assumptions on the state space and observation process. We give several examples of systems that satisfy these assumptions. We also show that the asymptotic structure of the filtering distribution is related to the dynamical properties of the signal.
Optimal pricing, ordering, and credit period policies for deteriorating products under order-linked trade credit
Authors: Tsao Yu-Chung , Fauziah Hanifa-Astofa , Vu Thuy-Linh , Masruroh Nur Aini
Published: September 2021

In the modern global economy, trade credit financing is typical in business transactions for both sellers and buyers. The seller offers a credit period to attract new buyers or stimulate demand, and the buyer takes the opportunity to accumulate revenue. To obtain this benefit, the seller prefers trade credit policies that are dependent on the quantity ordered, referred to as order-linked trade credit. The buyer can obtain the benefits from a fully delayed payment if their order is sufficiently large. Similarly, the seller can sell many products while granting a credit period. Otherwise, the buyer receives only partial trade credit, and the seller can take the opportunity of both cash and credit payments. In this study, an economic order quantity (EOQ) inventory model for deteriorating products, under default risk control-based trade credit, is formulated using a discounted cash flow approach. The seller offers to the buyer order-linked trade credit with price-and credit-period-dependent demand. The optimal selling price, credit period policies, and replenishment cycle time are determined simultaneously, while maximizing the present value of the seller's total profit. Moreover, this research provides numerical examples and sensitivity analysis to illustrate the theoretical results, solution procedure, and gain managerial insights. 200 words.

Published: September 2021

In this study, we consider a periodic dividend barrier strategy in an improved thinning risk model, which indicates that insurance companies randomly receive premiums and pay dividends. In the improved model, the premium is stochastic, and the claim counting process is a p-thinning process of the premium counting process. The integral equations satisfied by the Gerber-Shiu function and the expected discounted cumulative dividend function are derived. Explicit expressions of those actuarial functions are obtained when the claim and premium sizes are exponentially distributed. We analyze and illustrate the impact of various parameters on them and obtain the optimal barrier. Finally, a conclusion is drawn.

For any positive integer $ n $, let $ \mathbb Z_n: = \mathbb Z/n\mathbb Z = \{0, \ldots, n-1\} $ be the ring of residue classes module $ n $, and let $ \mathbb{Z}_n^{\times}: = \{x\in \mathbb Z_n|\gcd(x, n) = 1\} $. In 1926, for any fixed $ c\in\mathbb Z_n $, A. Brauer studied the linear congruence $ x_1+\cdots+x_m\equiv c\pmod n $ with $ x_1, \ldots, x_m\in\mathbb{Z}_n^{\times} $ and gave a formula of its number of incongruent solutions. Recently, Taki Eldin extended A. Brauer's result to the quadratic case. In this paper, for any positive integer $ n $, we give an explicit formula for the number of incongruent solutions of the following cubic congruence

   \begin{document}$ x_1^3+\cdots +x_m^3\equiv 0\pmod n\ \ \ {\rm with} \ x_1, \ldots, x_m \in \mathbb{Z}_n^{\times}. $\end{document}

Pork makes up the highest proportion of household expenditure on meat in China and supply and demand have been basically stable in the past decade. However, the catastrophic outbreak of African swine fever (ASF) in August 2018 disrupted the balance and reduced the national herd by half within six months. The consequence was a gross lack of supply to the market and consumer demand was unable to be met. Accordingly, live pig prices rose sharply from 2019. In order to assess the influence of ASF on the price of the live pigs, we use a price function to characterize the relationship between price of the live pigs and the nation's pig stock, and then establish a time delay ASF epidemic dynamical model with the price function. By analyzing the dynamical behaviors of the model, we calculate the basic reproductive number, discuss the stability of equilibrium, and obtain the critical conditions for Hopf bifurcation. The model reasonableness is confirmed by carrying out data fitting and parameter estimation based on price data of the live pigs, the pig stock data and the outbreak data of ASF. By performing sensitivity analysis, we intuitively show the impact of ASF on the price of live pigs and the pig stocks, and assess the key factors affecting the outbreak of ASF. The conclusion is drawn that, with the control measures adopted by related government department in China, the basic reproductive number ($ R_0 = 0.6005 $) means that the ASF epidemic has been controlled. Moreover, the price of the live pig increases linearly with $ R_0 $, while the effect of the number of infected pigs on the subsequent price is non-linear related. Our findings suggest that society and the government should pay more attention to the prevention of animal disease epidemics.

The diagnosis of the severity of spinal cord injury (SCI) and the revelation of potential therapeutic targets are crucial for urgent clinical care and improved patient outcomes. Here, we analyzed the overall gene expression data in peripheral blood leukocytes during the acute injury phase collected from Gene Expression Omnibus (GEO) and identified six m6A regulators specifically expressed in SCI compared to normal samples. LncRNA-mRNA network analysis identified AKT2/3 and PIK3R1 related to m6A methylation as potential therapeutic targets for SCI and constructed a classifier to identify patients of SCI to assist clinical diagnosis. Moreover, FTO (eraser) and RBMX (reader) were found to be significantly down-regulated in SCI and the functional gene co-expressed with them was found to be involved in the signal transduction of multiple pathways related to nerve injury. Through the construction of the drug-target gene network, eight key genes were identified as drug targets and it was emphasized that fostamatinib can be used as a potential drug for the treatment of SCI. Taken together, our study characterized the pathogenesis and identified a potential therapeutic target of SCI providing theoretical support for the development of precision medicine.

Industrial Cyber-Physical Systems (CPSs) require flexible and tolerant communication networks to overcome commonly occurring security problems and denial-of-service such as links failure and networks congestion that might be due to direct or indirect network attacks. In this work, we take advantage of Software-defined networking (SDN) as an important networking paradigm that provide real-time fault resilience since it is capable of global network visibility and programmability. We consider OpenFlow as an SDN protocol that enables interaction between the SDN controller and forwarding plane of network devices. We employ multiple machine learning algorithms to enhance the decision making in the SDN controller. Integrating machine learning with network resilience solutions can effectively address the challenge of predicting and classifying network traffic and thus, providing real-time network resilience and higher security level. The aim is to address network resilience by proposing an intelligent recommender system that recommends paths in real-time based on predicting link failures and network congestions. We use statistical data of the network such as link propagation delay, the number of packets/bytes received and transmitted by each OpenFlow switch on a specific port. Different state-of-art machine learning models has been implemented such as logistic regression, K-nearest neighbors, support vector machine, and decision tree to train these models in normal state, links failure and congestion conditions. The models are evaluated on the Mininet emulation testbed and provide accuracies ranging from around 91–99% on the test data. The machine learning model with the highest accuracy is utilized in the intelligent recommender system of the SDN controller which helps in selecting resilient paths to achieve a better security and quality-of-service in the network. This real-time recommender system helps the controller to take reactive measures to improve network resilience and security by avoiding faulty paths during path discovery and establishment.
Recipiency and peripheral participation in language brokering
Authors: Harjunpää Katariina
Published: September 2021

In a multilingual situation where some participants do not speak or understand one of the used languages, the participants need to balance between the language choice and the restrictions it creates for opportunities to participate. In this conversation analytic study, I examine how participants manage differentiated possibilities of participation in asymmetrically multilingual interactions in instances of language brokering and to what extent does brokering draw the recipient into the conversation. The paper concludes, first, that participants’ embodied displays of recipiency toward a main speaker, whose talk they cannot (fully) understand, as well as embodied displays of disengagement from the conversation, can serve to “recruit” linguistic assistance from others. Second, the broker’s orientations to the recipient’s participation status are reflected in the content of the brokering turns. The study thereby demonstrates how participants multimodally negotiate forms of peripheral participation and their accountability. The study argues that, although language brokering is done only occasionally and includes great variation in terms of how prior talk is translated, these practices are not random but result from a systematic interactional organization of action and participation.

In vision-driven development plans, such as the Kuwait Mid-Range Development Plan 2015/2016–2019/2020, themes and pillars are derived from the plan's vision, and global indices are assigned by international organizations to accurately measure the performance against the vision's themes. This allows for comparison with other countries, and it also set targets for progression over time. One or more projects are assigned to the indicators of these global indices. A Multi-Criteria Mathematical Programming Technique (e.g., Goal Programming) is used with multiple goals and priorities where an Optimal Portfolio of Projects is found that satisfied the selection criteria.

Published: September 2021

This paper presents a study of the screw extrusion parameters that affect on the appearance of clay filament for a clay printing machine. Traditionally, pottery models are formed by using paster mold or hand throwing, which require experienced and proficient workers to form the complex pottery models. Therefore, the clay printing machine has been developed to improve manual pottery fabrication to automatic construction. This machine has been modified based on the additive manufacturing (AM). To assess a capability material deposition of the clay printing machine, nozzle diameter, screw extruder velocity, and screw pitch were investigated as the printing parameters to evaluate a quality of clay filament. Analysis of variance (ANOVA) is used to analyze main effect parameters. The experimental results showed that the 6 mm nozzle diameter, 19 mm/s screw extruder velocity and 24 mm screw pitch were the suitable printing parameters for providing an appropriate appearance of clay filament. A mathematical model was formulated to propose the relationship between response and main effects with their interactions.

Authors: Mbeje Pretty N. , Mtshali Ntombifikile
Published: September 2021

Background: Reduced quality of life (QOL) is associated with shorter survival, and is more marked in patients with end-stage renal disease (ESRD). Predictors of health, which include policymaking, social factors, health services, individual behaviour, biology and genetics, have an impact on the QOL of patients with ESRD. Patients with ESRD in South Africa are cared for in public and private hospitals, with public health institutions characterised by several challenges.Objective: To explore and analyse the perceived predictors of QOL in patients with ESRD in the three district hospitals that provide renal services in KwaZulu-Natal.Methods: An exploratory, descriptive qualitative research approach based on grounded theory research design was used and three focus group discussions (FGDs) were conducted. The researcher recruited 18 participants, 6 in each focus group. Three phases of data analysis were followed: open coding, axial coding, and selective coding.Results: Predictors of QOL that emerged were the geographic location of the patients, accessibility of haemodialysis centres, patients’ adaptation and acceptance of the condition, self-management, support by family members and caregivers and availability of adequately trained nurses.Conclusion: Predictors of QOL in patients with ESRD are associated with an increased risk of morbidity and mortality resulting from dialysis. The broad range of dimensions of life is negatively affected and requires intervention by the renal team and policymakers to improve the QOL of patients.
Reading a few exemplary books or texts in the Pentateuch and comparing how these books or texts portray the theme of violence and disempowerment
Authors: Pietersen Doniwen
Published: September 2021

This research article focuses on selected Old Testament (OT) texts that deal with the theme of violence and disempowerment. The selected texts are studied and viewed from a feminist interpretation perspective, and laid bare the violent and mistreatment of women in these texts. This research study builds on the work of Phyllis Trible (1978), and she uses the term ‘texts of terror’ to refer to passages where women suffer especially at the hands of men. She believes that passages, such as Deuteronomy 22:5, are regrettable and should be a cause of repentance in order to avoid them being repeated again. The way this article deals with the aforementioned exemplary books or texts in the OT is to explore a gendered feminist lens to understand the theme of disempowerment or violence against women. This approach, with the data, lays bare to the reader the nature of the problem of disempowerment and violence against women.Contribution: This article brings a feminist understanding of the OT Bible (including its social-historical context) in order to gain a clearer insight into the problematic narratives of the disempowerment of and violence against women in a patriarchal society.
