Primates play a huge role in biomedical research. They are raised for medical research and to test new vaccines before being used for humans. The yellow-cheeked gibbon (Nomascus gabriellae) is an endemic mammal of Vietnam, included in the Vietnam Red Book 2007, and described in the IUCN Red Book 2009. ...

In this note, we prove a unique result for a nonlinear differential equation concerning a Nagumo-type source. An example is given to illustrate the theoretical result.

In engineering and science problems, the data being considered are often known in the form of sets of discrete points, not as a continuous function. In applications, the values of the discrete data at specific points may be required to estimate. To solve these problems, a common mathematical approach is ...

Nigeria and developing countries are suffering from infectious diseases due to a mixture of determinants. Parable, rotavirus is a major concern that causes a lot of deaths and hospitalization among children under five of age. Therefore, it is imperative to have more understanding of the rotavirus. A literature review to ...

This article provides a comprehensive review of ISBN codes, shedding light on their significance and outlining the process of generating a 13-digit ISBN check digit. ISBN codes (International Standard Book Number) play a crucial role in identifying and cataloging books, serving as a unique identifier for each publication.

The issue of marine pollution in general, as well as pollution brought on by oil spills into the sea, in rivers and lakes, or wastewater from factories, businesses, mechanical repair shops, gas stations, universities, and auto repair shops, is one that the world is currently facing, particularly since when it ...

In this paper, a high-order iterative scheme is established in order to get a convergent
sequence at a rate of order N, (N ≥ 2) to a local unique weak solution of a nonlinear
Kirchhoff-type wave equation associated with Robin conditions.

Enzymes are biodegradable catalysts naturally present in living organisms. Enzymes
can accelerate biochemical reactions by reducing the activation energy, and they are
not consumed during reaction processes. Numerous applications of enzymes have been
developed in biotechnology, industry, medicine, pharmaceuticals, food processing, biofuels,
and so on. In this study, we develop a mathematical model describing ...

In this work, we study the problem of finding the source function of the inhomogeneous
diffusion equations with conformable derivative c∂α
t u−Δu = f(x), 0 < α < 1, associate
with random noisy input data. This problem is ill-posed in the sense of Hadamard. In
order to regulate the instablity of the solution, ...

In this paper, we are interested in the problem of determining the source function forthe
Sobolev equation with fractional Laplacian. This problem is non-well-posed. We show theerror
estimate between the exact solution and the regularized solution with the observed data in Lb
spaces.

In this paper, we restate some applications of logarithms in Richter scale, pH scale and
sound intensity level (Decibel scale).

In this paper, we consider the Dirichlet boundary problem for a nonlinear wave equation
