Some summation theorems and transformations for hypergeometric functions of Kampé de Fériet and Srivastava
Authors: Srivastava Hari M. , Gupta Bhawna , Qureshi Mohammad Idris , Baboo Mohd Shaid 
Published: January 2024

Abstract
Owing to the remarkable success of the hypergeometric functions
of one variable, the authors present a study of some families
of hypergeometric functions of two or more variables. These functions
include (for example) the Kampé de Fériet-type
hypergeometric functions in two variables and Srivastava’s
general hypergeometric function in three variables. The
main aim of this paper is to provide several (presumably
new) transformation and summation formulas for appropriately
specified members of each of these families of hypergeometric
functions in two and three variables. The methodology and
techniques, which are used in this paper, are based upon
the evaluation of some definite integrals involving logarithmic
functions in terms of Riemann’s zeta function, Catalan’s constant,
polylogarithm functions, and so on.

Authors: Kim Hwankoo , Mahdou Najib , Oubouhou El Houssaine 
Published: January 2024

Abstract
This paper introduces and studies the ϕ-u-S-flat (resp., nonnil-u-S-injective) modules, which are a generalization of both ϕ-flat modules and u-S-flat modules (resp., both nonnil-injective modules and u-S-injective modules). We give the Cartan–Eilenberg–Bass theorem for nonnil-u-S-Noetherian rings. Finally, we offer some new characterizations of the ϕ-von Neumann regular ring.
Floquet theory and stability for a class of first order differential equations with delays
Authors: Domoshnitsky Alexander , Berenson Elnatan , Levi Shai , Litsyn Elena 
Published: January 2024

Abstract
A version of the Floquet theory for first order
delay differential equations is proposed. Formula of solutions representation is
obtained. On this basis, the stability of first order delay
differential equations is studied. An analogue of the classical integral Lyapunov–Zhukovskii
test of stability is proved. New, in comparison with all known, tests of the
exponential stability are obtained on the basis of the Floquet theory. A possibility to achieve the exponential stability is connected with oscillation of solutions.
Miss it like Messi: Extracting value from off-target shots in soccer
Authors: Baron Ethan , Sandholtz Nathan , Pleuler Devin , Chan Timothy C. Y. 
Published: January 2024

Abstract
Measuring soccer shooting skill is a challenging analytics problem due to the scarcity and highly contextual nature of scoring events. The introduction of more advanced data surrounding soccer shots has given rise to model-based metrics which better cope with these challenges. Specifically, metrics such as expected goals added, goals above expectation, and post-shot expected goals all use advanced data to offer an improvement over the classical conversion rate. However, all metrics developed to date assign a value of zero to off-target shots, which account for almost two-thirds of all shots, since these shots have no probability of scoring. We posit that there is non-negligible shooting skill signal contained in the trajectories of off-target shots and propose two shooting skill metrics that incorporate the signal contained in off-target shots. Specifically, we develop a player-specific generative model for shot trajectories based on a mixture of truncated bivariate Gaussian distributions. We use this generative model to compute metrics that allow us to attach non-zero value to off-target shots. We demonstrate that our proposed metrics are more stable than current state-of-the-art metrics and have increased predictive power.

Published: January 2024

Abstract
Nanotechnology is the most innovative field of the twenty-first century. Worldwide, intensive research is being done to commercialize nano products. Due to their unique or improved physical and chemical properties relative to bulk material, nanomaterials, especially nanoparticles have seen an enormous interest over the past few decades. As environmentally benign alternative nanoparticles are currently being produced “biologically” by means of plant or microorganism-mediated synthesis. Due to its outstanding biocompatibility, affordability, and low toxicity, and cost-effectiveness, ZnO NPs have emerged as one of the most widely used metal oxide nanoparticles in various applications. Interestingly, due to its multiple medical, health, environmental, and economic advantages, the green technique of synthesis employing plant materials has been discovered to be suitable for the production of ZnO nanoparticles. A variety of characterization methods have been used to assess the characteristics of ZnO NPs produced with green strategies, including X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FTIR), and UV–Vis spectroscopy and others. The value of these techniques reveals important information about the structural, morphological, and optical characteristics of ZnO NPs. In order to support future biomedical and other research, this review provides an overview of recent developments in the green synthesis of ZnO NPs with a focus on natural sources such as plants, bacteria, fungi, and algae as well as their characterizations, and various applications, including, antimicrobial, anticancer, antioxidant, photocatalytic, anti-inflammatory, anti-diabetics, and anti-aging applications.

Authors: Sanabria-Castro Alfredo , Alape-Girón Alberto , Flores-Díaz Marietta , Echeverri-McCandless Ann , Parajeles-Vindas Alexander 
Published: January 2024

Abstract
Multiple sclerosis (MS) is an autoimmune debilitating disease of the central nervous system caused by a mosaic of interactions between genetic predisposition and environmental factors. The pathological hallmarks of MS are chronic inflammation, demyelination, and neurodegeneration. Oxidative stress, a state of imbalance between the production of reactive species and antioxidant defense mechanisms, is considered one of the key contributors in the pathophysiology of MS. This review is a comprehensive overview of the cellular and molecular mechanisms by which oxidant species contribute to the initiation and progression of MS including mitochondrial dysfunction, disruption of various signaling pathways, and autoimmune response activation. The detrimental effects of oxidative stress on neurons, oligodendrocytes, and astrocytes, as well as the role of oxidants in promoting and perpetuating inflammation, demyelination, and axonal damage, are discussed. Finally, this review also points out the therapeutic potential of various synthetic antioxidants that must be evaluated in clinical trials in patients with MS.
Core Inflation Rate for China and the ASEAN-10 Countries: Smoothed Signal for Score-Driven Local Level Plus Scale Models
Authors: Blazsek Szabolcs , Licht Adrian , Ayala Astrid , Liu Su-Ping 
Published: January 2024

Abstract
We use a score-driven minimum mean-squared error (MSE) signal extraction method and perform inflation smoothing for China and the ASEAN-10 countries. Our focus on China and ASEAN-10 countries is motivated by the significant historical variation in inflation rates, e.g. during the 1997 Asian Financial Crisis, the 2007–2008 Financial Crisis, the COVID-19 Pandemic, and the Russian Invasion of Ukraine. Some advantages of the score-driven signal extraction method are that it uses dynamic mean and volatility filters, it considers stationary or non-stationary mean dynamics, it is computationally fast, it is robust to extreme observations, it uses information-theoretically optimal updating mechanisms for both mean and volatility, it uses closed-form formulas for smoothed signals, and parameters are estimated by using the maximum likelihood (ML) method for which the asymptotic properties of estimates are known. In the empirical application, we present the political and economic conditions for each country and analyze the evolution and determinants of the core inflation rate.

Abstract
Different strategies can be employed to enhance and adjust the overall characteristics and potential applications of the nanomaterials. Herein, ZnO–SiO2, Mn/ZnO–SiO2 and ZnO–SiO2/PVA based nanocomposites were synthesized by sol-gel and in-situ polymerization methods by taking the Zn(CH3COO)·2H2O as ZnO, TEOS as the SiO2 and Mn(SO4)2·7H2O as the Mn precursors. The present study investigates various aspects of ZnO–SiO2, Mn/ZnO–SiO2, and ZnO–SiO2/PVA nanomaterials, including electronic transition, surface morphology, elemental composition, chemical structure elucidation, thermal stability, and phase changes. To accomplish this, several techniques were employed. All the results confirmed the formation of the synthesized composite materials. Moreover, the catalytic and photocatalytic activities of the synthesized composites were studied through the degradation of Methylene blue (MB) dye, etc. The results confirmed that the synthesized nanocomposites exhibited good catalytic and photocatalytic activities towards removal of methylene blue (MB) dye removal. Further, the catalytic/photocatalytic activity of ZnO–SiO2, Mn/ZnO–SiO2 and ZnO–SiO2/PVA nanocomposites were also compared towards the removal of methylene blue (MB) dye and it was verified that the Mn/ZnO–SiO2 nanocomposite show high photocatalytic activity among the three nanocomposites i.e., ZnO–SiO2, Mn/ZnO–SiO2 and ZnO–SiO2/PVA with removal efficiencies of 81 %, 77 % and 77 %, after 6 h, 5 h and 9 h respectively, under UV light illumination. Moreover, the photodegradation mechanism was also studied and finally, the biological activities like antioxidant and antileishmanial were also studied and compared.

Published: January 2024

ABSTRACT
A comprehensive examination of psyching-up strategies before maximal force production is imperative to examine the efficacy of psyching-up, identify beneficial strategies for practitioners, and direct future investigations. The aim of this systematic review was to examine the efficacy of psyching-up strategies on maximal force production. The systematic review followed PRISMA guidelines. A systematic search was conducted in SPORTDiscus, PsychINFO, PsychARTICLES, MEDLINE, Google Scholar, and Web of Science. Studies were included if they used an experimental design, sampled adults, the independent variable included a psyching-up strategy that matched the working definition, and measured maximal force production measure. Twenty-seven independent studies met the inclusion criteria for this review. Collectively, 65% of the trials found that psyching-up facilitates maximal force production. Free-choice psyching-up, motivational self-talk, PETTLEP imagery, and prescribed preparatory arousal consistently enhanced performance. There was also evidence that disparity in the results may be because of the competitive experience of the participants and the type of control condition. The findings suggest that free-choice psyching-up, motivational self-talk, PETTLEP imagery, and prescribed preparatory arousal may enhance maximal force production. Future research should recruit experienced athletes to identify and test the efficacy of strategies used by applied practitioners.

The widespread use of glyphosate to eradicate weeds in agricultural areas has the potential for contamination and residues in the soil that must be carefully considered. This study aimed to elucidate the effect of glyphosate contamination on the chemical properties of an Inceptisol ameliorated with sub-bituminous coal. This study used a completely randomized design with three treatments and three replications, namely A = control (soil with no glyphosate and sub-bituminous coal), B = 5 kg soil + 100 mg glyphosate L-1, and C = 5 kg soil + 40 t sub-bituminous coal ha-1 + 100 mg glyphosate L-1. The results showed that glyphosate contamination significantly affected pH, electrical conductivity (EC), mineral and organic matter (OM) composition, cation exchange capacity (CEC), organic carbon (OC), total N, and available P of an Inceptisol ameliorated with sub-bituminous coal. The application of 40 t sub-bituminous coal ha-1 as an alternative ameliorant improved pH H2O by 0.30, EC by 0.05 dS m-1, OM by 1.03%, CEC by 18.08 cmol(+) kg-1, OC by 1.16%, total N by 0.20% and available P by 5.47 ppm of the soil compared to the control. The residual glyphosate concentration in the soil ameliorated with sub-bituminous coal was 0.04 mg kg-1 compared to the initial glyphosate concentration of 100 mg L-1. The correlation between glyphosate residue had no significant relationship with the chemical properties of an Inceptisol ameliorated with sub-bituminous coal.

Published: January 2024

Mount Merapi National Park (TNGM) is one of the active volcanos in Indonesia. It has past volcano eruption history since 1911 up to date. Specifically, Plawangan Hill is a part of the TNGM recently designated as Geo-heritage and has experienced volcano eruption indirectly and directly. Additionally, since the Indonesian government designates Plawangan Hill as a Geological Heritage (Geo-Heritage) location, it is crucial to determine its geological features and how they relate to the development of the vegetation there as the studyâ€™s objectives. A field survey and a soil laboratory examination were conducted to obtain the data. As a result, Plawangan Hillâ€™s DEM was classified from very low to very high classes, while the DSM was categorized from flat to very steep slopes. Further, the results demonstrated that the pH of theÂ soil was typically somewhat acidic (5.93â€“6.54). While the soilâ€™s nitrogen content was found to be low to medium, both phosphorusÂ and potassium levels were typically very low. The carbon-nitrogen ratio wasÂ generally categorized into the medium, while the organic C ranged from low to medium (1.44% to 3.22%). The soilâ€™s N total, K total, organic matter, carbon content, and C-N ratio increased by the erupted material age. Additionally, it was discovered that the vegetation growth was excellent in indirect (IA) and directly affected (DA) conditions, as indicated by their diameter at breast height (Dbh) and height (H). The correlationÂ between soil characteristics andÂ vegetationÂ growth differed in indirectly affected (IA) and directly affected (DA) areas. As a result, the study found that volcanic materials significantly contributed toÂ Plawangan Hillâ€™s soil characteristics and vegetation growth. Furthermore, this studyâ€™s findings were highly beneficial because they were one of the primary explanations for why Plawangan Hill was designated a Geo-heritage site.

Published: January 2024

Iron oxide nanoparticles (NPs) have potential in biological, biomedical, and environmental applications because of their magnetic susceptibility, stability, and biocompatibility characteristics. However, it also has limitations, such as the aggregation of magnetic NP. Thus, the outer surface of the particles should be modified by coating materials. This paper focused on synthesizing iron oxide by chemical reduction method and coating it with Fe(III) nitrate, PVP, and hydrazine. The coating solution at two different concentrations was prepared to determine effective and economical usage conditions. The effect of coating iron oxide with microcrystalline cellulose (MCC) was conducted at different concentrations of iron oxide on the nanomaterials with respect to morphological, thermal, and magnetic susceptibility. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) indicated good morphology images of FeNp-MCC. Energy dispersive X-ray (EDX) spectra reveal the presence of carbon, oxygen, and iron in the synthesized microparticles.TGA analysis showed iron material was succesfully formed into the surface of microcrystalline cellulose. Lastly,the magnetism results proved that cellulose is strongly interacting with magnetite nanoparticles.

Abstract. This research aims to determine the birth process, the dynamics of the formulation, and the impact of the licensing policy for ex-corruption convicts to participate in elections. By using qualitative research methods and public policy theory, political elites, and corruption, this study found that the licensing policy for ex-corruption convicts in elections is a political process on the basis of providing opportunities for ex-corruption convicts as part of human rights which is then set forth in Law Number 7 of 2017 as a legal decree. Therefore, General Election Commission Regulation (PKPU) Number 20 of 2018 which prohibits ex-corruption convicts from becoming election participants is in itself considered deviant. This policy reaped a lot of controversy and rejection from society, but on the pretext of providing opportunities and fulfilling human rights, the political process came to a decision to be legalized through law. As a result, in the midst of public knowledge about the limited track record of politicians and the attitude of the people towards non-corruption which tends to be permissive, legislative candidates with backgrounds of corruption convicts have emerged and some have been elected in political contests at both the local and national levels. Keywords: Political rights, Ex-Corruption Convicts, Elections, Public Policy, Political Elite. Abstrak. Penelitian ini bertujuan untuk mengetahui proses lahir, dinamika perumusan, dan dampak kebijakan perizinan mantan narapidana korupsi ikut serta dalam pemilu. Dengan menggunakan metode penelitian kualitatif dan teori kebijakan publik, elite politik, dan korupsi, penelitian ini menemukan bahwa kebijakan perizinan mantan narapidana korupsi dalam pemilu merupakan proses politik atas dasar pemberian kesempatan mantan narapidana korupsi sebagai bagian dari hak asasi manusia yang kemudian dituangkan dalam UU No. 7 Tahun 2017. Oleh sebab itu, Peraturan KPU (PKPU) Nomor 20 Tahun 2018 yang melarang mantan narapidana korupsi menjadi peserta pemilu dengan sendirinya dianggap menyimpang. Kebijakan ini menuai banyak kotroversi dan penolakan dari masyarakat, namun atas dalih pemberian kesempatan dan pemenuhan HAM, maka proses politik sampai pada keputusan untuk dilegalisasi melalui undang-undang. Dampaknya, di tengah pengetahuan masyarakat tentang track record politisi yang terbatas dan sikap masyarakat terhadap tindak korupsi yang cenderung permisif, maka bermunculan calon-calon legislatif berlatar belakang narapidana korupsi dan sebagian terpilih dalam kontestasi politik baik pada tingkat lokal maupun nasional. Kata Kunci: Hak politik, Mantan Narapidana Korupsi, Pemilu, Kebijakan Publik, Elite Politik.
