Contact manifolds, Lagrangian Grassmannians and PDEs

Complex Manifolds, 2018
In this paper we review a geometric approach to PDEs. We mainly focus on scalar PDEs in n independent variables and one dependent variable of order one and two, by insisting on the underlying (2n + 1)-dimensional contact manifold and the so-called ...

A Higher Order Chebyshev-Halley-Type Family of Iterative Methods for Multiple Roots

Mathematics, 2019
The aim of this paper is to introduce new high order iterative methods for multiple roots of the nonlinear scalar equation; this is a demanding task in the area of computational mathematics and numerical analysis. Specifically, we present a new Chebyshev&

Numerical Models of Cosmological Evolution of the Degenerated Fermi-system of Scalar Charged Particles

, 2014
Based on mathematical model of the statistical Fermi system with the interparticle interaction which was constructed in the previous articles, this work offers the construction and analysis of the numerical models of cosmological evolution of the single ...

Enabling visually impaired people to learn three-dimensional tactile graphics with a 3DOF haptic mouse

Journal of NeuroEngineering and Rehabilitation, 2021
Background In this work, we present a novel sensory substitution system that enables to learn three dimensional digital information via touch when vision is unavailable. The system is based on a mouse-shaped device, designed to jointly perceive, with one

Wheeler-DeWitt Quantization of Gravity Models of Unified Dark Energy and Dark Matter

, 2017
First, we describe the construction of a new type of gravity-matter models based on the formalism of non-Riemannian space-time volume forms - alternative generally covariant integration measure densities (volume elements) defined in terms of auxiliary ...

Trans-Sasakian static spaces

Results in Physics, 2021
Static spaces (with perfect fluids) appeared in a natural way both in physics (cf. Hawking and Ellis, 1975) and mathematics (cf. A. Fischer and J. Marsden, Duke Math. J. 42 (3) (1975), 519–547).

Psychometric Properties of the Sources of Counseling Self Efficacy in a Sample of Malaysian Secondary School Counselors

SAGE Open, 2020
Self-efficacy has been considered an essential mediator and predictor of individual counseling performance. As there is no existing scale to measure counseling self-efficacy in the counseling domain, the Sources of Middle School Mathematics Self-Efficacy

Integral and fractional equations, positive solutions, and Schaefer's fixed point theorem [PDF]

Opuscula Mathematica, 2016
This is the continuation of four earlier studies of a scalar fractional differential equation of Riemann-Liouville type \[D^qx(t) = -f(t,x(t)), \quad \lim_{t\to 0^+} t^{1-q} x(t) = x^0 \in\Re \quad (0 \lt q \lt 1), \tag {a}\] in which we first invert it ...

Detecting homologous recombination deficiency for breast cancer through integrative analysis of genomic data

Molecular Oncology, EarlyView.
This study develops a semi‐supervised classifier integrating multi‐genomic data (1404 training/5893 validation samples) to improve homologous recombination deficiency (HRD) detection in breast cancer. Our method demonstrates prognostic value and predicts chemotherapy/PARP inhibitor sensitivity in HRD+ tumours.
