Diffusion in a disk with inclusion: Evaluating Green’s functions

open access: yesPLoS ONE, 2022
We give exact Green’s functions in two space dimensions. We work in a scaled domain that is a circle of unit radius with a smaller circular “inclusion”, of radius a, removed, without restriction on the size or position of the inclusion.

On the solution arising in two-cylinders electrostatics

open access: yesMathematical Biosciences and Engineering, 2023
The electrostatics of two cylinders charged to the symmetrical or anti-symmetrical potential is investigated by using the null-field boundary integral equation (BIE) in conjunction with the degenerate kernel of the bipolar coordinates.

Stress State in an Eccentric Elastic Ring Loaded Symmetrically by Concentrated Forces

open access: yesMathematics, 2022
The stress state from an eccentric ring made of an elastic material symmetrically loaded on the outer boundary by concentrated forces is deduced. The analytical results are obtained using the Airy stress function expressed in bipolar coordinates.

Ultrasonic Guided Waves for Liquid Water Localization in Fuel Cells: An Ex Situ Proof of Principle

open access: yesSensors, 2022
Water management is a key issue in the design and operation of proton exchange membrane fuel cells (PEMFCs). For an efficient and stable operation, the accumulation of liquid water inside the flow channels has to be prevented.

Network Analysis and Visualization of Mouse Retina Connectivity Data. [PDF]

open access: yesPLoS ONE, 2016
The largest available cellular level connectivity map, of a 0.1 mm sample of the mouse retina Inner Plexiform Layer, was analysed using network models and visualized using spectral graph layouts and observed cell coordinates. This allows key nodes in the

Tracking the current in the Alzheimer's brain - Systematic differences between patients and healthy controls in the electric field induced by tDCS

open access: yesNeuroImage: Reports, 2023
Background: Several studies on patients with Alzheimer's disease (AD) have used transcranial direct current stimulation (tDCS) to enhance neural excitability in the left dorsolateral prefrontal cortex (lDLPFC).

Curves with rational chord-length parametrization [PDF]

open access: yes, 2008
It has been recently proved that rational quadratic circles in standard Bezier form are parameterized by chord-length. If we consider that standard circles coincide with the isoparametric curves in a system of bipolar coordinates, this property comes as ...

Ellipsoidal, Cylindrical, Bipolar and Toroidal Wormholes in 5D Gravity [PDF]

open access: yes, 2001
In this paper we construct and analyze new classes of wormhole and flux tube-like solutions for the 5D vacuum Einstein equations. These 5D solutions possess generic local anisotropy which gives rise to a gravitational running or scaling of the Kaluza ...
