Poisson measures on semi-direct products of infinite-dimensional Hilbert spaces
Authors: Penney Richard C. , Urban Roman
Published: July 2023

Let \(G=X\rtimes A\) where X and A are Hilbert spaces considered as additive groups and the A-action on G is diagonal in some orthonormal basis. We consider a particular second order left-invariant differential operator L on G which is analogous to the Laplacian on \(\mathbb{R}^n\). We prove the existence of "heat kernel" for L and give a probabilistic formula for it. We then prove that X is a "Poisson boundary" in a sense of Furstenberg for L with a (not necessarily) probabilistic measure ν on X called the "Poisson measure" for the operator L.

Uniqueness for optimal control problems of two-dimensional second grade fluids
Authors: Almeida Adilson , Chemetov Nikolai V. , Cipriano Fernanda
Published: July 2023

We study an optimal control problem with a quadratic cost functional for non-Newtonian fluids of differential type. More precisely, we consider the system governing the evolution of a second grade fluid filling a two-dimensional bounded domain, supplemented with a Navier slip boundary condition. Under certain assumptions on the size of the initial data and parameters of the model, we prove second-order sufficient optimality conditions. Furthermore, we establish a global uniqueness result for the solutions of the first-order optimality system.

Authors: Goyal Sarika , Sharma Tarun
Published: July 2023

In this article, we study the existence and multiplicity of solutions to the fractional Kirchhoff Hardy problem involving weighted Choquard and singular nonlinearity $$\displaylines{ M(\|u\|^2)(-\Delta)^su - \gamma\frac{u}{|x|^{2s}} = \lambda \frac{l(x)}{ u^q} + \frac{1}{|x|^{\alpha}} \Big({\int_{\Omega}\frac{r(y)|u(y)|^p}{|y|^{\alpha}|x-y|^\mu}\,dy}\Big)r(x)|u|^{p-2}u \quad \hbox{in } \Omega, \cr u>0 \hbox{ in } \Omega, \quad u = 0 \hbox{ in } \mathbb{R}^N\backslash\Omega, }$$ where \(\Omega\subseteq \mathbb{R}^N\) is an open bounded domain with smooth boundary containing 0 in its interior, \(N>2s\) with \(s\in(0,1)\), \(0<q<1\), \(0<\mu<N\), \(\gamma\) and \(\lambda\) are positive parameters, \(\theta\in [1, p)\) with \(1 < p < 2^*_{\mu,s,\alpha}\), where \(2^*_{\mu,s,\alpha}\) is the upper critical exponent in the sense of weighted Hardy-Littlewood-Sobolev inequality. Moreover M models a Kirchhoff coefficient, l is a positive weight and r is a sign-changing function. Under the suitable assumption on l and r, we established the existence of two positive solutions to the above problem by Nehari-manifold and fibering map analysis with respect to the parameters.The results obtained here are new even for s=1.
Boundary-domain integral equations for Dirichlet diffusion problems with non-smooth coefficient
Authors: Fresneda Portillo Carlos , Woldemicheal Zenebe W.
Published: July 2023

We obtain a system of boundary-domain integral equations (BDIE) equivalent to the Dirichlet problem for the diffusion equation in non-homogeneous media. We use an extended version of the boundary integral method for PDEs with variable coefficients for which a parametrix is required. We generalize existing results for this family of parametrices considering a non-smooth variable coefficient in the PDE and source term in \(H^{s-2}(\Omega)\), \(1/2< s <3/2\) defined on a Lipschitz domain. The main results concern the equivalence between the original BVP and the corresponding BDIE system, as well as the well-posedness of the BDIE system

Existence of solutions to nonlocal elliptic problems with singular and combined nonlinearities
Authors: Tordecilla Jesus Alberto Leon
Published: July 2023

We use an approximation scheme together with a variation of the fixed point theorem to show the existence of a positive solution to a nonlocal boundary value problem. This problem has a smooth bounded domain in RN, a singular term, and combined nonlinearities. We also study the symmetric, monotonicity, and asymptotic behavior of the solutions with respect to a parameter involved in the problem.

Authors: Qu Siqi , He Xiaoming
Published: July 2023

In this article we study the fractional Schrodinger-Poisson system $$\displaylines{ \epsilon^{2s}(-\Delta)^s u+V(x)u=\phi |u|^{2^*_s-3}u,\quad x\in \mathbb{R}^3, \cr (-\Delta)^s\phi=|u|^{2^*_s-1}, \quad x\in \mathbb{R}^3, }$$ where \(s\in(1/2,1)\), \(\epsilon>0\) is a parameter, \(2^*_s=6/(3-2s)\) is the critical Sobolev exponent, \(V\in L^{\frac{3} {2s}}(\mathbb{R}^3)\) is a nonnegative function which may be zero in some region of \(\mathbb{R}^3\). By means of variational methods, we present the number of high energy bound states with the topology of the zero set of V for small \(\epsilon\).
Localized nodal solutions for semiclassical nonlinear Kirchhoff equations
Authors: Wang Lixia
Published: July 2023

In this article, we consider the existence of localized sign-changing solutions for the semiclassical Kirchhoff equation  $$ -(\varepsilon^2a+\varepsilon b\int_{\mathbb{R}^3}|\nabla u|^2dx) \Delta u+V(x)u =|u|^{p-2}u, \quad x\in \mathbb{R}^3,\; u\in H^1({\mathbb{R}^3}) $$where \(4
0\) is a small parameter, \(V(x)\) is a positive function that has a local minimum point \(P\). When $\varepsilon\to 0$, by using a minimax  characterization of higher dimensional symmetric linking structure via the symmetric mountain pass theorem, we obtain an infinite sequence of localized sign-changing solutionsclustered at the point \(P\).
Higher differentiability for solutions to nonhomogeneous obstacle problems with 1<p<2
Authors: Wang Zhenqiang
Published: July 2023

In this article, we establish integer and fractional higher-order  differentiability of weak solutions to non-homogeneous obstacle problems that satisfy the variational inequality $$ \int_{\Omega} \langle A(x,Du),D(\varphi-u)\rangle\,dx \ge \int_{\Omega} \langle |F|^{p-2}F,D(\varphi-u)\rangle\,dx, $$where \(1< p<2\), \(\varphi \in \mathcal{K}_{\psi } (\Omega ) =\{ v\in u_0+W_0^{1,p}(\Omega ,\mathbb{R} ):v\ge \psi \text{ a.e.\ in } \Omega\} \), \)(u_0\in W^{1,p}(\Omega)\) is a fixed boundary datum.We show that the higher differentiability of integer or fractional order of thegradient of the obstacle \(\psi\) and the nonhomogeneous term F can transfer to the gradient of the weak solution, provided the partial map \(x\mapsto A(x,\xi)\)belongs to a suitable Sobolev or Besov-Lipschitz space.

Authors: El Bazi Hamza , Sadrati Abdellatif
Published: July 2023

This work concerns the existence of a fixed point for mixed monotone nearly asymptotically nonexpansive mappings. We extend and generalize some well-known results concerning nearly asymptotically nonexpansive mappings in a uniformly convex hyperbolic metric space. As application of our results, we study the existence of solutions for an integral equation.
Heat kernel estimates for fourth-order non-uniformly elliptic operators with non-strongly convex symbols
Authors: Barbatis Gerassimos , Branikas Panagiotis
Published: July 2023

We obtain heat-kernel estimates for fourth-order non-uniformly elliptic operators in two dimensions. Contrary to existing results, the operators considered have symbols that are not strongly convex. This entails certain difficulties as it is known that, as opposed to the strongly convex case, there is no absolute exponential constant. Our estimates involve sharp constants and Finsler-type distances that are inducedby the operator symbol. The main result is based on two general hypotheses, a weighted Sobolev inequality and an interpolation inequality, which are related to the singularity or degeneracy of the coefficients.
Extending Lagrangian transformations to nonconvex scalar conservation laws
Authors: Dutta Prerona
Published: July 2023

This article studies a method of finding Lagrangian transformations, in the form of particle paths, for all scalar conservation laws having a smooth flux. These are found using the notion of weak diffeomorphisms. More precisely, from any given scalar conservation law, we derive a Temple system having one linearly degenerate and one genuinely nonlinear family. We modify the system to make it strictly hyperbolic and prove an existence result for it. Finally we establish that entropy admissible weak solutions to this system are equivalent to those of the scalar equation. This method also determines the associated weak diffeomorphism.

Infinitely many solutions and asymptotics for resonant oscillatory problems
Authors: Korman Philip , Schmidt Dieter S.
Published: July 2023

For a class of oscillatory resonant problems, involving Dirichlet problems for semilinear PDE's on balls and rectangles in \(\mathbb{R}^n\), we show the existence of infinitely many solutions, and study the global solution set.  The first harmonic of the right hand side is not required to be zero, or small.  We also derive asymptotic formulas in terms of the first harmonic of solutions, and illustrate their accuracy by numerical computations. The numerical method is explained in detail.

Theory Of Allophones
Authors: Tara Arini  , Yani lubis  , Rahmi Pitriyani
Published: July 2023

The phoneme theory is a well-known phonological theory from the late 19th century (1870) which aims to find out the abstract representation of the phonemes of a given language. To find out whether a phoneme is a phoneme, a phonemic analysis rule is used that states: (1) mutually exclusive neighborhood of complementary distribution, known as the allophone of the same phoneme, (2) a phone in a minimal pair, known as the different phoneme, like /p/ and /b/,(3) a phone in an environment analogous to, like for example /Z/, (4) a phone as a free variant is not another phoneme, but a variation of a phoneme of /c/ the phonemes /č/ and /čh/ are variations of the phoneme /č/. A prosodic phoneme is recognized by a toneme and a chronoma. Daniel Jones' consonant and vowel analysis rule proved inadequate to solve all consonantrelated problems. Trubetskoy and Jacobson made a breakthrough in analyzing a phoneme by a distinguisher and a contrast. The analyzed componentsare: opposition system, bilateral and multilateral opposition system, prepositional opposition system and emotional opposition including the formation of neutralized phonemes and archiephonemes in German.

Comparative Performance of Irradiated and Non- Irradiated Carrageenan-Based Foliar Fertilizers on the Growth, Yield, and Pest Incidence of Pechay (Brassica rapa L.)
Authors: Trangia Maria Lyca , Macusi Erna
Published: July 2023

This study evaluated and compared the effects of supplementing irradiated and non-irradiated carrageenan-based foliar fertilizers with the same source, Kappaphycus alvarezii, on the growth, yield, and pest incidence of pechay (Brassica rapa L.) plants, as well as to determine their profitability. The VitalGro Carrageenan Plant Growth Promoter (CPGP) and the Kappaphycus Drippings Foliar Fertilizer (KDFF) were used as the irradiated and the non-irradiated carrageenan-based foliar fertilizers, respectively. The experiment was laid out using a Randomized Complete Block Design (RCBD) with four treatments: T1 = 0 application (negative control), T2 = Farmer’s Practice (positive control), T3 = Farmer’s Practice + VitalGro CPGP, and T4 = Farmer’s Practice + KD Foliar Fertilizer (KDFF), replicated four times. Analysis of Variance (ANOVA) was used to analyze the data with the Duncan Multiple Range Test (DMRT) to compare differences in treatment means. Profitability was determined using cost and return analysis. Supplementation of VitalGro CPGP and KDFF exhibited comparable results in increasing the height (p = .000) and number of leaves (p =.008) of pechay plants. Various insect pests were detected throughout the experimentation, but the most damaging pest was the cabbage webworm (Crocidolomia binotalis) which was found to be highest (p = .000) in plants treated with the non-irradiated KDFF. While no pest repelling effects were observed in both the carrageenanbased foliar fertilizers, plants supplemented with VitalGro CPGP were noted to be the most tolerant and gained the highest Yield (p=.001) despite pest attack, thereby achieving the highest return of investment (ROI) at 94.86%.

Designing a combined Markov-bayesian model in order to predict stock prices in the stock exchange
Authors: Hajiaghajani Azam
Published: July 2023

Investing in shares offered on the stock exchange is one of the most profitable options in the capital market. The stock market has a non-linear and chaotic system that is influenced by political, economic, and psychological conditions. Forecasting time series, such as stock price forecasting, is one of the most important problems in the field of economics and finance because the data is unstable and has many variables that are influenced by many factors. There are many ways to predict stock prices. Non-linear intelligent systems such as artificial neural networks, fuzzy neural networks, and genetic algorithms can be used to predict stock prices. In this research, a hybrid system based on Bayesian networks and the Markov model is proposed to predict the daily trend of the stock market. Bayesian networks are used to specify relationships between variables in forecasting. Finally, the Markov model is used to predict the market trend in the sets extracted from the Bayesian network. The evaluation criteria in the proposed system show the high efficiency of this method.
Identifying and ranking key performance indicators in football clubs
Authors: Rahmati Kianoush
Published: July 2023

Key performance indicators are actually measurable variables based on which we can measure the success rate of an organization in reaching defined key goals. In order to create key performance indicators, steps, and standards must be passed, each of which is of great importance. Based on how the key performance indicator (KPI) is defined and determined, it is possible to measure the performance of a person, department, process, campaign, or strategic goals of a brand. In fact, KPIs can be considered for different industries and for different levels of each business. Considering the importance of football clubs and their high social impact, the purpose of this research is to investigate these key performance indicators in order to grow and improve their comprehensive performance. In order to extract data, a literature review was used. Data refinement and prioritization were done using the fuzzy decision-making method, and the opinions of active experts in clubs and football players were used. The results show that indicators based on infrastructure development are among the most important indicators and should be given special attention.

Published: July 2023

In the multicultural and interconnected society, digital technology has become an essential pedagogical tool for teachers in rural areas, whose fundamental task is to integrate digital technology into the educational context. This study analyzes and evaluates the self-perception of teachers about their digital competence and the relationship with their performance in the intercultural environment of rural secondary education. The research approach was quantitative, non-experimental descriptive-correlational design, with a sample of 192 rural secondary education teachers from Huánuco-Peru, using the survey technique through the questionnaire instrument, validated by expert judgment.  The results indicate that the digital competence and intercultural vision of teachers in rural areas is direct, on average more than 58% assume to have developed their digital competence at a high or very high level, while more than 71% have a positive perception about intercultural education; the Spearman correlation coefficient between the two variables is 0.75. It is concluded that there is a direct and complementary relationship between the development of digital competence and the interculturality of teachers, which leads to an efficient management of the teaching-learning process.

Published: July 2023

The Peruvian education system in general and primary education in particular, in the post-pandemic stage, has been going through one of the most critical moments due to the increase in the social gap and access to technology by students, which is expressed in the heterogeneity in learning reinforced with discriminatory positions that lead to manifestations of hatred.  This study aims to determine the influence of hate speech on cognitive learning and emotional learning of students in the fifth and sixth grades of Primary Education. The methodology used responds to a field study with a sample of 128 students from the two grades of study, a dichotomous questionnaire is administered and another adapted to the Likert scale referring to the dimensions of hate speech, cognitive and emotional learning. Among the results stand out: more than 50% achieved medium or low emotional learning, the average cognitive learning is regular (11,664), there is a negative relationship between hate speech and emotional learning of students. It is concluded that the practice of discourse among students in the fifth and sixth grade of primary education significantly influences their level of cognitive and emotional learning, a fact that has implications for their personal, social and intellectual training.
Displacement and Marginalisation of Haitian Immigrants
Authors: Manpreet Kaur Uppal  , Meenakshi Rana
Published: July 2023

Displacement is the forced or voluntary migration of people. Colonialism and Imperialism are the significant factors that lead to the displacement and dislocation of people. Economic poverty and natural calamities add to the physical movement of people from one country to another. The migrants suffer physically and psychologically in the host countries. The fear of non-acceptance leads to their marginalisation in society. Marginalisation is a social phenomenon in which ethnic minorities or sub-groups are excluded from mainstream society. When an individual migrates, he aspires to acceptance in the host country. The natives do not find any semblance to the migrants and do not accept them; they treat them indifferently, demean them, and use derogatory terms for them. The immigrants find it difficult to adapt and feel secluded and marginalised. Edwidge Danticat writes about the immigration of Haitians and the problems they faced after immigration. The immigrants are displaced in the host country and feel alienated when they do not find any help or solace. They face social, economic, political, cultural and psychological marginalisation. The marginalised are always at the receiving end, and their needs are ignored. These marginalised people may develop low self-confidence and self-esteem.

Published: July 2023

The purpose of this study is to investigate the building blocks of organizational learning among female workers in the SMEs. A descriptive quantitative research methodology was adopted. A survey was distributed to 702 female employees working for SMEs. Descriptive and multiple regression analyses were used to describe the data and test the hypothesis. This result reveals that SMEs are making efforts at creating and gathering knowledge among female employees, and it also demonstrates that the utilization of organizational learning has a positive impact on the productivity of organizations; however, there is an issue in the layout of the supportive learning environments in SMEs where the positive result is very small in comparison to concrete learning processes and leadership that reinforces learning processes and practices. Conclusion, recommendations, and future research orientation are discussed in the paper.

Background: The Cysteine-Cysteine Receptor 5 (CCR5) molecule is the most important co-receptor for macrophage-tropic HIV-1. A 32-bp deletion in the gene encoding CCR5 (CCR5-del32) confers nearly complete resistance to HIV-1 infection in homozygotes, and slows the rate of progression to AIDS in heterozygous adults. This study aimed to determine the frequencies of chemokine receptor 5 (CCR5) genes alleles associated with V3 loop of glycoprotein (gp) 120 among HIV patients in Yenagoa, Nigeria. Methods: Genomic DNA was extracted from whole 100 blood samples using Quick gDNA Mini Prep kit. A portion of the CCR5 gene and gp 120 regions of HIV-1 DNA were amplified from the gDNA by PCR with sequence specific primers and universal primers respetively followed by agarose gel electrophoresis. DNA sequencing of the resultant gp 120 amplicon was also carried out. Results: The CCR5 gene was positive at 189bp. None was positive to the CCR5/Δ32 heterozygous and none was also positive to the Δ32 homozygous deletion. The V3 region of the HIV DNA was seen to be positive at 250bp. Conclusion: This study shows that there is Single nucleotide polymorphism (SNP) of the protein sequence in the V3 region of gp120 among positive individuals in the study population.

Published: July 2023

Expression of MicroRNAs (miRNAs), key regulators of normal haematopoiesis, is reportedly dysregulated in acute myeloid leukaemia (AML).Aberrant microRNA expression has been associated with different subtypes of AML, where they exert tumor suppressive or oncogenic functions. Deregulated microRNA expression has been shown to be of prognostic significance. Furthermore, it has been demonstrated that repression and ectopic expression of microRNAs affect response to treatment in AML. Consequently, microRNAs may act as potential biomarkers in AML hence production of new anti-AML drugs directed towards increasing and/or silencing miRNA expression may suffice.

Introduction: The presence of rare blood group antibodies in the blood of donors/recipients stimulate red cell alloimmunization and constitute a major cause of transfusion related reaction after a compatible ABO cross match, yet remain one of the less routinely assessed prior to blood donation and transfusion in Nigeria. This cross-sectional study was carried out among indigenes of Bonny kingdom in Rivers State Nigeria to access the percentage expression of Lewis B, Rh-e, N and ABO antigens in descent of Bonny Kingdom Rivers State Nigeria. Materials and Methods:- One hundred and twenty (120) apparently healthy subjects consisting of sixty (60) females and sixty (60) males aged between 18-50 years all indigenes of Bonny Kingdom were recruited by structured questionnaire for the study. 4mls of venipuncture blood was aseptically collected from each participant into vacutainer bottle containing 0.5 mL of 1.2 mg/mL dipottasium ethylenediaminetetraacetic acid anticoagulant and a 5% cell suspension was prepared and used to determine the various blood groups antigens using the standard tube Agglutination technique. Results: Results obtained shows a total of 94.1% (113) of the participants expressed Rh-e antigen, 45.8% (55) male and 48.3% (58) females. 7.5% (9) of the participants expressed the N antigen, 3.3% (4) male and 4.2% (5) females. 4.2% (5) of the study population expressed Lewis B antigen, 2.5% (3) males and 1.7% (2) female. The ABO system showed 68.5% (79) O blood group, 29.1% (35) male and 36.7% (44) female. 22(18.3%) typed for A blood group, 11.6% (14) male and 6.7% (8) female. For B blood group 14.2% (17) persons were typed, 7.5% (9) male and 6.7% (8) female while 1.6% (2) persons were typed as AB and they are all females. Conclusion: Rh-e phenotype occurred highest among the study participants. The proportion of the population without the expression of these antigens of the blood group tested has the potential to be alloimmunized during blood transfusion and develop antibodies, some of which can be responsible for transfusion reactions and haemolytic disease of the new born. This study has provided baseline data on the distribution of some blood group antigens in the Bonny Kingdom of Rivers State in Nigeria. Based on the finding in this study, it is recommended that Rh-e grouping be carried out on pregnant mothers, blood donors and recipients before transfusion; while Lewis B and N blood groups may be subjected to expansive population testing.

Introduction: Although viremia has been greatly addressed in the management of human immunodeficiency virus (HIV) infection by the advancement in antiretroviral therapy, not all HIV-associated morbidities have been resolved. Observations of increased cardiovascular risk in relation to antiretroviral therapy have been reported. Full blood count continues to be useful in disease management, and efforts are directed towards optimising its utility in medical practice. Derivatives of blood cell counts have in recent times proved to be informative with regards to the inflammatory-thrombotic cycle. The utility of these derived parameters in HIV within the study locality is worth exploring. Methods: This single-site study was carried out at University of Calabar Teaching Hospital in Calabar, Cross River State of Nigeria. White blood cell and platelet counts were carried out by automation, while blood cell ratios were calculated. Statistical analysis of data was done using SPSS 22.0. A p-value of ≤ 0.05 was considered to infer a statistically significant difference. Results: Significant reductions of white blood cell parameters were recorded in HIV, particularly among infected persons on antiretroviral therapy. Platelet count and plateletcrit were significantly lower, while mean platelet volume and platelet distribution width were higher in newly diagnosed persons compared to HIV-infected subjects on therapy and control subjects. Platelet-to-lymphocyte ratio was significantly higher among subjects on therapy compared to the rest of the groups. Conclusion: Increase in platelet count following antiretroviral therapy could be posing a risk of platelet-driven morbidities as typified in the observed elevated thrombotic marker.
