Unsteady thermal Maxwell power law nanofluid flow subject to forced thermal Marangoni Convection

open access: yesScientific Reports, 2021
In the current work, the unsteady thermal flow of Maxwell power-law nanofluid with Welan gum solution on a stretching surface has been considered. The flow is also exposed to Joule heating and magnetic effects.

A numerical method for solving ill-posed problems for two-dimensional integral equations of the first kind

open access: yesНаука. Инновации. Технологии, 2022
Propose a method of numerical solution integral equations of the first kind. This assumes that the source data in the equation can be set approximately with errors, and the integral equation kernel may have features that leads to the formulation of so ...

The computational content of Nonstandard Analysis [PDF]

open access: yes, 2016
Kohlenbach's proof mining program deals with the extraction of effective information from typically ineffective proofs. Proof mining has its roots in Kreisel's pioneering work on the so-called unwinding of proofs.

Single-Particle Cryo-Electron Microscopy: Mathematical Theory, Computational Challenges, and Opportunities

open access: yesIEEE Signal Processing Magazine, 2020
In recent years, an abundance of new molecular structures have been elucidated using cryo-electron microscopy (cryo-EM), largely due to advances in hardware technology and data processing techniques. Owing to these new exciting developments, cryo-EM was selected by Nature Methods as Method of the Year 2015, and the Nobel Prize in Chemistry 2017 was ...

The Ontological Role of Applied Mathematics in Virtual Worlds

open access: yesPhilosophies, 2022
In this paper, I will argue that with the emergence of digital virtual worlds (in video games, animation movies, etc.) by the animation industry, we need to rethink the role and authority of mathematics, also from an ontological point of view.

Introduction to Gestural Similarity in Music. An Application of Category Theory to the Orchestra

open access: yes, 2018
Mathematics, and more generally computational sciences, intervene in several aspects of music. Mathematics describes the acoustics of the sounds giving formal tools to physics, and the matter of music itself in terms of compositional structures and ...

Matrix Structure Exploitation in Generalized Eigenproblems Arising in Density Functional Theory

open access: yes, 2009
In this short paper, the authors report a new computational approach in the context of Density Functional Theory (DFT). It is shown how it is possible to speed up the self-consistent cycle (iteration) characterizing one of the most well-known DFT ...

Group theory and biomolecular conformation: I. Mathematical and computational models [PDF]

open access: yesJournal of Physics: Condensed Matter, 2010
Biological macromolecules, and the complexes that they form, can be described in a variety of ways ranging from quantum mechanical and atomic chemical models, to coarser grained models of secondary structure and domains, to continuum models. At each of these levels, group theory can be used to describe both geometric symmetries and conformational ...

A consequence of the notional existence of an effectively calculable yet non-recursive function

open access: yesAnalecta Cracoviensia, 2021
The present paper is devoted to a discussion of the role of Church’s thesis in setting limits to the cognitive possibilities of mathematics. The specific aim is to analyse the formalized theory of arithmetic as a fundamental mathematical structure ...

Guarded Cubical Type Theory: Path Equality for Guarded Recursion [PDF]

open access: yes, 2016
This paper improves the treatment of equality in guarded dependent type theory (GDTT), by combining it with cubical type theory (CTT). GDTT is an extensional type theory with guarded recursive types, which are useful for building models of program logics,
