Fast Addition for Multiple Inputs with Applications for a Simple and Linear Fast Adder/Multiplier And Data Structures
Authors: Ramirez Juan Pablo 
Published: June 2023

A construction for the systems of natural and real numbers is presented in Zermelo-Fraenkel Set Theory that allows for simple proofs of the properties of these systems, and practical and mathematical applications. A Simple and Linear Fast Adder (SLFA - Patent Pending) is a direct consequence of this construction of natural and real numbers. The \(n\)-bit adder performs addition in \(\log n\) time and has linear topology. Minor add-ons allow for a SLFA to add \(m\)-many \(n\)-bit numbers, and multiplication can be implemented. Applications to group theory and analysis are also presented. Finite functions are coded as natural numbers in such a way that they are given a well-behaved and total order. Finite permutations are a well-behaved embedded suborder. The set of finite groups is also given a well-behaved and total order. Finding the numerical representation of a finite group provides a canonical block form for the group's Cayley table, the automorphisms of the group, and the minimal independent system of equations that define the group. The construction of natural numbers is generalized to provide a simple and transparent construction of the continuum of real numbers, with order and operations. A fast derivative algorithm is proposed in the same section. As in the finite case, where finite structures can be represented by a single natural number, similar results hold in the infinite case. A countable sequence of real numbers is coded by a single real number. Furthermore, an infinite \(\infty\times\infty\) real-valued matrix is represented with a single real number. A real function is coded by a set of real numbers, and a countable sequence of real functions is also coded by a set of real numbers. In general, mathematical objects are coded using the smallest possible data type and these representations are computable and manipulable. In the last section, mathematical objects of all types are well assigned to tree structures in a proposed hierarchy of types.
Can the electromagnetic fields form tensors if D = ϵE and H = B/µ?
Authors: Franklin Jerrold 
Published: June 2023

One of the bases of relativistic electromagnetism is that the electromagnetic fields \(\bf E\) and \(\bf B\) are components of an electromagnetic field tensor \(F^{\mu\nu}\). There is a simple proof of this in the absence of a polarizable medium. It has sometimes been assumed that the fields, \(\bf E\) and \(\bf B\), and their associated fields, \(\bf D=\epsilon E\) and \(\bf H=B/\mu\), are also components of tensors in a linearly polarizable medium. In this paper, we question that assumption, and show that a proof that they are components of a tensor fails. Consequently, the fields \(\bf E\), \(\bf B\), \(\bf D\) and \(\bf H\) are not components of a relativistic tensor in a linearly polarizable medium.

Published: June 2023

The moral degradationthat has occurred in Indonesia has resulted in increasingly rampant crime, including among children who are often found in cases of fights with each other, against their parents, bullying, and other crimes. This happens because of a lack of parenting and character education from parents, family and those closest to them, so that these children form their own character without considering good or bad forthemselvesandtheirenvironment. The reality of orphans who don't have a father or mother makes character a very crucial problem, considering that they don't get complete love and affection like children in general, sometimes they are even far from the characteristic values of Islam. The purpose of this research is to provide an over view of the implementation of prophetic parenting, and to find out the role of orphanages as charitable and social institutions in educating and caring for orphans who need a place to live, substitute parents, propereducation, and fulfillment of other needs. This study uses descriptive qualitative methods through instruments such as interviews, field observations, and documentation. Prophetic parenting style emphasizes exemplary aspects, aspects of habituation, aspects of education and teaching, and social aspects of society
Toward a Sustainable Future: An Exploratory Approach to the Dynamics of Europe’s Urban Morphology and Sustainability
Authors: Lovie Jacob 
Published: June 2023

<p>As cities continue to expand, and more of humanity moved from rural setting into urbanized areas, there is an important need to understand the impacts of how we urbanize on the environment. Knowledge on how to urbanize sustainably can ensure that we ae managing our global footprint on the environment while still progressing as a society. The research takes a multi-step approach to understand the dynamics of urbanization across Europe and its impact on environmental sustainability. 36 metrics that comprised the analysis of the urban landscape configuration and 8 metrics used to analyse the urban land composition of countries across Europe were tested against the human development index (HDI) and ecological footprint (EF) to understand the relationships between urban morphology and sustainability. Data was retrieved across four sets of years, 2000, 2006, 2012 and 2018 to ensure correlations were consistent and to understand if there were changes over time. The study first explored the bivariate relationships between the landscape metrics and sustainability indicators. After this, spatial relationships were explored through a Global Moran’s <em>I </em>test at both global and local levels to reveal spatial autocorrelation among any variables. Finally, key metrics identified were used in two multivariate analysis. Ordinary Least Squares (OLS) was first computed to create global models and to find an optimized model for each year and were computed separately for each indicator. Conditional Autoregressive (CAR) models were then computed on the most optimized models to reduce bias of spatial autocorrelation among the variables and to validate against the OLS models. Finally, a temporal exploration of key variables was conducted to see the trends of variables over time. The results showed that there are important relationships among urban morphology and its impact on both socio-economic and environmental sustainability. </p>

In this study, the performance and structural properties of enhanced skinned asymmetric nanofiltration (NF) membranes were experimentally and theoretically analyzed. Based on Donnan and steric-hindrance transport mechanism, the relationship of performances and key properties of the fabricated nanofiltration membranes were examined. At the optimum concentration of polymer, the skinned nanofiltration membranes achieved high salt rejection up to 85% and high solutes separation efficacy. Moreover, morphological and modeling analysis discovered that, the optimum membranes produced good pore size and fine key properties with 1.20 nm of pore radius, 4.96 µm of ratio of thickness to porosity (∆x/Ak) and −1.56 of surface charge, ζ as well as uniform pore size distributions. The findings from this study proved that the strategic utilization and manipulation of good membranes material is a simple and good attempt to upgrade the membranes capability and usability which lead towards the application in various membrane separation processes.

Published: June 2023

Background: The fimbrial end of the fallopian tube has recently been suggested as the site of origin for epithelial ovarian cancers (EOC). Therefore, a change in practice with opportunistic salpingectomy (OS) at the time of hysterectomy has been advocated for prevention of ovarian cancer in a low-risk population.
Objective: The aim of this study was to analyzethe current trend of performing opportunistic salpingectomy during gynaecological surgery for benign indicationsin a tertiary care hospital of Bangladesh.
Materials and method: This retrospective observational study was conducted in the Department of Obstetrics & Gynaecology, BIRDEM Women and Children Hospital, Dhaka, Bangladesh from October 2019 to March 2022. All relevant demographic and clinical information of 255 patients undergoing hysterectomy for benign gynaecological disease without involving the ovaries or adnexae were documented from hospital records after exclusion of patients with any gynecologic cancer or having any ovarian or adnexal pathology, and those who underwent hysterectomy due to pregnancy related conditions.
Results: Mean age of the patients was 48.71 ± 8.31 years and the highest proportion of patients (49.0%) were in the 41-50 years of age group. Bilateral salpingo-oophorectomy was done in 131 cases (51.4%) with mean age of 51.95 ± 7.99 years and opportunistic salpingectomy was done in 72 cases (28.2%) with mean age of 42.68 ± 3.97 years. The rate of opportunistic salpingectomy statistically increased from 17.39% in 2019 to 36.17% in 2022.
Conclusion: As seen throughout the world, the practice of opportunistic salpingectomy for prevention of ovarian cancer has also increased in Bangladesh in recent years.

El derecho a la identidad de los menores concebidos por fecundación post mortem
Authors: Cali-Coronel Marco , Aguilar-Guiracocha Johanna , Barrera-Bravo Fausto 
Published: June 2023

Con el surgimiento de las técnicas de reproducción humana asistida, nacen para el derecho dinámicas familiares distintas a las que tradicionalmente conocemos, la fecundación post mortem es una de ellas y plantea la posibilidad de que las mujeres puedan concebir a un nuevo ser aún después de la muerte de su cónyuge o compañero sentimental, empleando para ello el material genético de la persona fallecida (esperma) o embriones constituidos pero que no han sido implantados en la mujer. En este contexto, este artículo analizó la problemática que conlleva el nacimiento de personas mediante la técnica de fecundación post mortem y la imposibilidad de poder relacionar al hijo con el padre fallecido, lo que ocasiona que el derecho a la identidad de estos menores se vea afectado debido a no poder garantizar a plenitud uno de los elementos que componen este derecho, para ello, se empleó el método sistemático a fin de determinar el alcance de este derecho y las implicaciones de esta práctica en caso de suscitarse en el Ecuador. Con ello, se pudo evidenciar que si bien la Constitución de la República reconoce y garantiza el derecho a la identidad, existen todavía barreras que impiden que todos los niños puedan ver materializado su derecho, debido a la falta de regulación en el Ecuador en lo referente al acceso, procedimientos y requerimientos en el uso de las técnicas de reproducción humana asistida.
La víctima de trata frente al delito de tráfico ilícito de sustancias catalogadas sujetas a fiscalización: ¿Una salida jurídica aplicable en Ecuador?
Authors: Troya-Arellano Cristina 
Published: June 2023

El presente trabajo de investigación pretende demostrar que la ‘‘mula’’ del narcotráfico es una víctima dentro del delito de trata de personas con fines sexuales bajo ciertos parámetros establecidos en la normativa ecuatoriana comparándola con la legislación argentina. También, se procederá a estudiar el delito de narcotráfico y sus absoluciones evidenciando que las ratio deciden di de las salas se basa sobre otros conceptos como: la competencia de jurisdicción indígena, principio de favorabilidad en comparación a la disminución de penas del delito de tráfico ilícito de sustancias catalogadas sujetas a fiscalización ( en adelante delito de narcotráfico), mala práctica de pruebas, entre otras. Sin dejar de lado, el análisis a la legislación argentina la misma que tiene puntos en común con la realidad ecuatoriana y es aplicable bajo nuestro ordenamiento jurídico.
Cabe destacar que el tema no ha sido estudiado en Ecuador en los últimos siete años. Más bien, con la entrada del Código Orgánico Integral Penal (en adelante COIP) se consolidó una diferencia entre las escalas de narcotráfico y se dejó de discutir sobre la legislación ecuatoriana referente a drogas. En efecto, es menester visualizar la falta de utilización del artículo 93 del COIP sobre el principio de no punibilidad de la víctima de trata, el mismo que al ser tan amplio da un argumento válido a la defensa del correo humano de droga al evidenciar su calidad de víctima. Pero, es importante establecer los requisitos para que pueda apreciarse esta eximente de pena como son evidenciar la explotación, su participación en el narcotráfico como producto del abuso y la proporcionalidad coherente entre la situación originada y el delito cometido.

Mathematical modeling for the control of fly-borne mastitis disease in cattle
Authors: Adeyemi Moses Olayemi , Oluyo Temitayo Olabisi 
Published: June 2023

Several diseases cause losses in cattle farming, especially in the dairy industry among which mastitis disease (Bovine mastitis) is the leading cause of health and economic damages globally as it results in animals' ill health and reduced quality and quantity of milk produced by infected cows. Some mathematical studies have been conducted that focused on mastitis transmission from one udder-quarter to another in an infected cow, even though clinical studies established the cow–cow and flies–cow transmissions. The present study, therefore, proposed a mathematical model for the control of mastitis disease in cattle in the presence of flies as vectors. The formulated model was shown to have non-negative solutions in feasible regions for both cattle and flies populations. Furthermore, the model has a stable disease-free equilibrium if the sum of the effective reproduction numbers for cattle–cattle and fly–cattle transmissions (ℜch and ℜch) is less than unity, and there is a possibility of multiple endemic equilibria if otherwise. The numerical results indicated that the infectious populations can be reduced if the rates of the control parameters are increased, thereby curtailing or eradicating mastitis in the cattle population.

Purpose: To compare bilateral differences in corneal biomechanics between keratoconus and normal eyes.Methods: In this case-control study, 346 eyes of 173 patients (aged 22.1 ± 6.1 years) with keratoconus (KC group) and 378 eyes of 189 patients (aged 26.7 ± 5.6 years) with ametropia (control group) were enrolled. Corneal tomography and biomechanical properties were examined using Pentacam HR and Corvis ST, respectively. The corneal biomechanical parameters were compared between eyes with forme fruste keratoconus (FFKC) and normal eyes. Bilateral differences in corneal biomechanical parameters were compared between the KC and control groups. Receiver operating characteristic (ROC) analysis was used to assess discriminative efficacies.Results: The areas under the ROC curves (AUROCs) of stiffness parameter at the first applanation (SP-A1) and Tomographic and Biomechanical Index (TBI) for identifying FFKC were 0.641 and 0.694, respectively. The bilateral differential values of major corneal biomechanical parameters were significantly increased in the KC group (all p &lt; 0.05), except for the Corvis Biomechanical Index (CBI). The AUROCs of the bilateral differential values of the deformation amplitude ratio at 2 mm (ΔDAR2), Integrated Radius (ΔIR), SP-A1 (ΔSP-A1), and the maximum inverse concave radius (ΔMax ICR) for discriminating keratoconus were 0.889, 0.884, 0.826, and 0.805, respectively. The Logistic Regression Model-1 (comprising of ΔDAR2, ΔIR, and age) and the Logistic Regression Model-2 (comprising of ΔIR, ΔARTh, ΔBAD-D, and age) had AUROCs of 0.922 and 0.998, respectively, for discriminating keratoconus.Conclusion: The bilateral asymmetry of corneal biomechanics was significantly increased in keratoconus compared with normal eyes, which may be helpful for the early detection of keratoconus.

Introduction: Chronic osteomyelitis remains a clinical challenge in orthopedics.Methods: In this study, silk fibroin microspheres (SFMPs) loaded with vancomycin are entrapped in an injectable silk hydrogel to form a vancomycin delivery system for treatment of chronic osteomyelitis.Results and Discussion: Vancomycin showed continuous release from the hydrogel for up to 25 days. The hydrogel shows strong antibacterial activity against both Escherichia coli and Staphylococcus aureus and a long antibacterial duration of 10 days without a decrease in the antibacterial effect. The injection of vancomycin-loaded silk fibroin microspheres entrapped in the hydrogel into the infected site of rat tibia reduced bone infection and improved bone regeneration compared with other treatment groups.Conclusion: Thus, the composite SF hydrogel features a sustained-release profile and good biocompatibility, making it promising for application in osteomyelitis treatment.
