Ambient Noise Data Processing to Obtain Group Velocity for Subsurface Structure Identification: Preliminary Research in Hululais Geothermal Field, Sumatra, Indonesia

open access: yesJGEET: Journal of Geoscience, Engineering, Environment and Technology, 2023
Hululais area lies in the pull-apart basins of the Ketaun Segment and Musi Segment fault as a part of the Sumatra Fault Zone (SFZ). The boundary normal faults of pull-apart basins play an important role as major discharge zones for geothermal fluid ...

Melt strength and stretching ratio of low-density polyethylene composites loaded with nanoscale zinc oxide

open access: yesAdvanced Industrial and Engineering Polymer Research, 2020
The melt drawability including melt strength (MS) and stretching ratio (V) of the neat low-density polyethylene (LDPE) and the LDPE composites loaded with a nanometer zinc oxide (nano-ZnO) were measured using a melt spinning method in capillary extruding

Existence of positive continuous weak solutions for some semilinear elliptic eigenvalue problems [PDF]

open access: yesOpuscula Mathematica, 2022
Let \(D\) be a bounded \(C^{1,1}\)-domain in \(\mathbb{R}^d\), \(d\geq 2\). The aim of this article is twofold. The first goal is to give a new characterization of the Kato class of functions \(K(D)\) that was defined by N.

Discrete Green's Functions

open access: yesJournal of Combinatorial Theory, Series A, 2000
The authors study discrete Green's functions and their relationship with discrete Laplace equations. They give different ways to construct such functions: Eigenfunctions or Cartesian product of graphs, among others.

INCEPTION OF GREEN FUNCTION FOR THE THIRD-ORDER LINEAR DIFFERENTIAL EQUATION THAT IS INCONSISTENT WITH THE BOUNDARY PROBLEM CONDITIONS

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2021
Regarding the importance of teaching linear differential equations, it should be noted that every physical and technical phenomenon, when expressed in mathematical sciences, is a differential equation.

The best constant of Sobolev inequality corresponding to anti-periodic boundary value problem

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2014
In this paper we establish the best constant of $\mathcal{L}^{p}$ Sobolev inequality for a function with anti-periodic boundary conditions. The best constant is expressed by $\mathcal{L}^q$ norm of $(M-1)$-th order Euler polynomial.

Responses of unicellular predators to cope with the phototoxicity of photosynthetic prey

open access: yesNature Communications, 2019
Photosynthesis generates reactive oxygen species that can damage cells. Here, the authors show that unicellular predators of photosynthetic prey have shared responses to photosynthetic oxidative stress and these may also have been important for the ...

A q-oscillator Green’s function [PDF]

open access: yesJournal of Mathematical Physics, 1997
By using the generating function formula for the product of two q-Hermite polynomials, q-deformation of the Feynman Green’s function for the harmonic oscillator is obtained.

BOUNDARY VALUE PROBLEM WITH SHIFT FOR A FRACTIONAL ORDER DELAY DIFFERENTIAL EQUATION [PDF]

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2019
In this paper we prove existence and uniqueness theorem to a boundary value problem with shift for a fractional order ordinary delay differential equation. The solution of the problem is written out in terms of the Green function.

GREEN FUNCTIONS FOR TOPOLOGY CHANGE [PDF]

open access: yesInternational Journal of Modern Physics A, 2005
We explicitly calculate the Green functions describing quantum changes of topology in Friedmann-Lemaître-Robertson-Walker Universes whose spacelike sections are compact but endowed with distinct topologies. The calculations are performed using the long wavelength approximation at second order in the gradient expansion.
