Existence of solutions for a degenerate seawater intrusion problem

Electronic Journal of Differential Equations, 2005
We study a seawater intrusion problem in a confined aquifer. This process can be formulated as a coupled system of partial differential equations which includes an elliptic and a degenerate parabolic equation.

Band Offsets from Angle‐Resolved Valence Band Photoemission Spectroscopy

Advanced Materials Interfaces, EarlyView.
Soft X‐ray Angle‐Resolved Photoemission Spectroscopy (SX‐ARPES) is employed to quantify conduction band offsets at semiconductor surfaces and interfaces by fitting valence band photoemission spectra. This method surpasses traditional techniques, providing accurate results for InAs and InSb systems.

The mathematics of suspensions: Kac walks and asymptotic analyticity

Electronic Journal of Differential Equations, 2000
Of concern are suspension flows. These combine directed and random motions and are typically modelled by parabolic partial differential equations.

Live Quantitative Characterization for Stem Cell Biomechanics

Advanced Materials Interfaces, EarlyView.
These findings demonstrate an accessible technique for real‐time, high‐resolution mechanical mapping of live stem cells, without the use of specialised probes or advanced modelling techniques. This approach provides direct insight into localised cytoskeletal dynamics under chemical treatment and holds potential for broader application in understanding ...

A Two-Dimensional Nonlocal Fractional Parabolic Initial Boundary Value Problem

Axioms
In this paper, we investigate a two-dimensional singular fractional-order parabolic partial differential equation in the Caputo sense. The partial differential equation is supplemented with Dirichlet and weighted integral boundary conditions.

Rotary 4D Printing of Programmable Metamaterials on Sustainable 4D Mandrel

Advanced Materials Technologies, EarlyView.
The paper introduces open, rotary 4D printing of programmable tubular metamaterials. It presents an open, non‐planar path‐to‐G‐code pipeline and shape‐changing rotary mandrel that enable support‐free fabrication and multi‐stimuli actuation. Experiments and FEA validate the mentioned features and stress redistribution.
