Authors: Hedayati Maryamsadat , Ezzati Reza 
Published: March 2024

Abstract
This study aims to propose novel Zernike wavelets and a new method based on the operational matrices for solving nonlinear fractional differential equations. First, non-orthogonal Zernike wavelets are introduced using the Zernike polynomials. Then, a new technique based on combining these wavelets with the block pulse functions is presented to derive the operational matrix of fractional integration and to solve nonlinear fractional differential equations. Moreover, an error analysis is conducted by providing required theorems. Besides, the proposed method is employed to solve a nonlinear fractional competition model of breast cancer. Finally, a parametric study is performed to consider the effect of fractional order on the population of healthy, cancer stem, tumour, and immune cells, as well as the excess estrogen.
New solutions for the generalized q-deformed wave equation with q-translation symmetry
Authors: Shehata Ahmed S. , Raslan Kamal R. , Ali Khalid K. 
Published: March 2024

Abstract
In this work, we explore the generalized discrete wave equation, which utilizes a specific irregular space interval. The introduction of this irregular space interval is motivated by its connection to the q-addition, a mathematical operation that arises in the nonextensive entropy theory. By taking the continuous limit, we obtain the wave equation with q-deformation, which captures the effects of the q-addition. To solve the generalized q-deformed wave equation, we investigate three different methods: the separation method, the reduced differential transform method, and the finite difference method. These methods offer distinct approaches for finding solutions to the equation. By comparing the results obtained from each method, we can evaluate their effectiveness and identify their respective strengths and limitations in solving the generalized q-deformed wave equation. The solutions obtained from this newly defined equation have potential applications in modeling physical systems with violated symmetries. The inclusion of the q-deformation allows for a more comprehensive description of such systems, which may exhibit nonextensive behavior or possess irregularities in their spatial intervals. By incorporating these features into the wave equation, we can improve our understanding and modeling capabilities of complex physical phenomena.

Abstract
The development of stable carrageenan nanoparticles connected to the sulfate functional group of carrageenan and barium ion for the use of selectively targeting cancer cell and imaging contrast to help with diagnosis (tracing/imaging) is the concern of the present research. This study provides an overview of ion substitution chemistry, highlighting the role of ions and how they affect the applicability of carrageenan. The characteristic of barium sulfate, which is widely used as radiopaque to provide contrast for diagnostic radiographic examinations in the gastrointestinal mucosa, is provided by its linkage with the barium ion despite K+’s natural binding with carrageenan. The additional role of the Ba ion linked carrageenan was found highly selective for cancer cell through the in vitro cell line assay; however, the nonattachability to the normal cell makes useful to trace and treat the cancer cell. The tracing is possible because of the barium sulfate functional group and its nanosize molecule, which shows precision medicine, fluorescence, and X-ray/CT imaging character, to be utilized as the diagnostic purpose, especially to tumor cell. The apoptosis from the Ba2+ ion by the inhibition of outflux of K+ to disturb the osmosis of cell and selectivity of the molecules because of high pKa (Logarithms of acid dissociation constant) value, which makes the drug more active anionic (nonpolar) form in the cancer cell and ionic form (polar) in the normal cell, which avoids the interaction with normal cell and facilitate the interaction with cancer cell. In conclusion, the cancer cell selectivity with fluorescence and radiopaque properties of Ba ion linked carrageenan makes the molecule useful for tracing, imaging, and treating cancer cell with high selectivity.

Abstract
Selective removal of 99TcO₄− from radioactive wastewater is a challenging but significant task, which benefits spent fuel reprocessing and radioactive-waste leakage treatment. This work introduces the performance of adsorption ReO4
− using a series of novel anion exchange resins, namely MAPE-1, MAPE-2, MAPE-3, and MAGD-1, impregnated with functionalized ionic liquids as active sites. They exhibit a high selectivity towards TcO₄−/ReO₄−, in a wide pH range of pH 5–11 for ReO₄−/TcO₄− adsorption. Among these resins, MAPE-1 has the best adsorption performance for ReO4
−, with a maximum adsorption capacity of 202.4 mg/g and a high distribution ratio K

d
of 6.2 × 10⁶ mL/g at pH 7. The adsorption mechanism involves anion exchange between functionalized ionic liquids and TcO₄−/ReO₄−, which is supported by X-ray energy dispersive spectroscopy (EDS) and Fourier Transform Infrared spectroscopy (FT-IR) analyses. In addition, X-ray photoelectron spectroscopy (XPS) further illustrates the interaction between the resin and perrhenate.

Published: March 2024

Lithium-Ion (Li-ion) battery is essential in today's energy systems and electric vehicles (EVs). Although Li-ion battery can be charged quickly and have a high energy density, it has several drawbacks, including the rapid degradation of battery performance, especially in terms of battery capacity. Therefore, evaluating its performance degradation is necessary to understand its characteristics. In this paper, the performance degradation of a Li-ion battery is monitored and evaluated from multiple SoC measurements. A simple and low-cost experimental setup consisting of sensors, a microcontroller, and a PC is developed to measure and record the real-time data of Li-ion battery voltage and current. Then, the battery state of charge (SoC) is determined using the Coulomb Counting method, which is based on the incoming and outgoing currents of the battery. As a result, this study derives three parameters that indicate the performance degradation of a Li-ion battery, i.e., SoC, battery capacity, and discharge time. From multiple direct measurements with constant load and C20 discharge process, the minimum SoC value increases from 11% to 18%, while battery capacity decreases from 8.8Ah to 8.3 Ah and, discharge time decreases from 16.9 hours to 16.4 hours. All of those parameters indicate a degradation of around 7% in battery performance. Therefore, this research paves the way for finding a solution to mitigate the quick performance degradation of Li-ion batteries.
Sequential Detection under Correlated Observations using Recursive Method

Published: March 2024

Sequential analysis has been used in many cases when the decision is supposed to be taken quickly such as for signal detection in statistical signal processing, namely sequential detector. For identical error probabilities, a sequential detector needs a smaller average sample number (ASN) than its counterpart of a fixed sample number quadrature detector based on Neyman-Pearson criteria. The optimum sequential detector was derived based on the assumption that the observations are uncorrelated (independent). However, in realistic scenario, such as in radar, the assumption is commonly violated. Using a sequential detector under correlated observations is sub-optimal and it poses a problem. It demands a high computational complexity, since it needs to recalculate the inverse and the determinant of the signal covariance matrix for each new sample taken. This paper presents a technique for reducing the computational complexity, which involves using recursive matrix inverse to subsequently calculate conditional probability density functions (pdf). This eliminates the need to recalculate the inverse and determinant, leading to a more reasonable solution in real-world scenario. We evaluate the performance of the proposed (recursive) sequential detector by using Monte-Carlo simulations and we use the conventional and non-recursive sequential detectors for comparisons. The results show that the recursive sequential detector has equal probabilities of false alarm and miss-detection with the conventional sequential detector and performs better than the non-recursive sequential detector. In terms of ASN, it maintains comparable results to the two conventional detectors. The recursive approach has reduced the computational complexity for matrix multiplication to from and it also has rendered the calculation of matrix determinant to be unnecessary. Therefore, by having better probabilities of error and reduced computational complexities under correlated observations, the proposed recursive sequential detector may become a viable alternative to obtain a more agile detection system as required in future applications, such as in radar and cognitive radio.

The structure of mercury-modified amorphous films of the Se-Sb system was studied using the methods of X-ray diffractometry and Raman spectroscopy. It was ascertained that the structure of the phase that formed in the amorphous matrix of the films after their exposure in mercury vapor corresponds to the structure of crystalline mercury selenide in cubic modification.
The structure of nominally pure and mercury-modified amorphous Se100Sbx films (x = 3, 5, 7, 9) was investigated using X-ray diffractometry and Raman spectroscopy. It is shown that the matrix of nominally pure films is built mainly by elements of Se8 rings and Sen helical chains and contains a certain number of SbSe3/2 structural groups. Exposure of the films in mercury vapor leads to formation of mercury selenide (HgSe) crystalline inclusions in the cubic modification in their near-surface layers, as well as to the activation of the process of formation and growth of Se crystalline inclusions of the trigonal modification in the film bulk.

Electrochemical double-layer capacitors use porous carbons as the electrode material, and improving their performance requires an understanding of the electrolyte−carbon surface interactions. 13C, 14N, and 11B NMR spectroscopy were used to investigate the behaviour of the electrolytes [C(OCH3)3NH3]+Cl- and [N(CH2CH3)]+BF4- on the surface of porous carbon in D2O solutions. A chemical shift of 13C has been found in the fragments N–C, indicating electron density redistribution between nitrogen atoms and alkyl fragments. The presence of a signal with a chemical shift of d = 7.7 confirms the structuring of the electrolytic layer of water solution [N(CH2CH3)]+BF4-.

La salud sexual y reproductiva -SSYR, es un tema importante para jóvenes y adolescentes, especialmente cuando se trata de prevenir embarazos y enfermedades de trasmisión sexual, sin embargo, en personas con discapacidad auditiva y del lenguaje esta situación suele ser más compleja. El objetivo de esta propuesta consistió en identificar los conocimientos que tienen adolescentes y jóvenes con discapacidad auditiva y del lenguaje sobre salud sexual y reproductiva en Cartagena.
El diseño metodológico de este estudio fue de naturaleza cuantitativa, descriptivo y transversal. La muestra fueron 41 jóvenes y adolescentes entre los 12 y 24 años de edad a los que se les aplicó un instrumento en lengua de señas colombianas sobre aspectos sociodemográficos y conocimientos en SSYR, previa firma de asentimiento y consentimiento informado. La población estuvo comprendida principalmente por adolescentes entre los 15 y 19 años en un 54%, de sexo femenino con un 68%. En cuanto a los conocimientos se logró evidenciar que el 53% de los encuestados tienen un conocimiento adecuado respecto a la SSYR, sin embargo, el 47% tiene conocimiento entre moderados e inadecuados frente al tema; algunos aspectos que llaman la atención es pensar que una mujer no puede quedar embarazada después de la menstruación (49%), considera que el condón es 100% seguro (54%) y que una mujer en su primera relación coital no puede quedar embarazada (44%).
Se determinó que los conocimientos sobre salud sexual y reproductiva en jóvenes y adolescentes con discapacidad auditiva fueron adecuados, pero con un alto porcentaje de conocimientos entre moderados e inadecuados. Razón por la cual, hay que seguir fortaleciendo aspectos como: anatomía y fisiología sexual y reproductiva ciclo de respuesta sexual humana, prevención de ETS y métodos anticonceptivos como alternativa de prevención de embarazos.

Objective: to analyze the health, drug, and antineoplastic drug lawsuits in Minas Gerais, in 2014 to 2020, from the comparison of different databases. Methodology: database pairing techniques were used to link lawsuits from the Minas Gerais State Court of Justice with the processes received by the Minas Gerais Health State Department, the difficulties encountered in identifying and quantifying these processes were described, and the results found were compared with information from other sources. Results: in the Minas Gerais State Court of Justice databases, 564,763 health lawsuits were identified in the studied period. There was a significant increase in the number of processes until 2017 and a stabilization, at high levels, from 2017 onwards. In comparison with the results obtained by the Institute of Higher Education and Research and the Laboratory of Innovation, Intelligence and Sustainable Development Goals there was a great divergence in the number of processes found. Conclusion: taking the health judicialization against Minas Gerais state as an example, it was not possible to directly find all the processes received by Minas Gerais Health State Department in the various databases provided by the Minas Gerais State Court of Justice, requiring integration between the different databases and an additional search to identify all processes.
