Disentangling Aleatoric and Epistemic Uncertainty in Physics‐Informed Neural Networks: Application to Insulation Material Degradation Prognostics

Advanced Intelligent Systems, EarlyView.
Physics‐Informed Neural Networks (PINNs) provide a framework for integrating physical laws with data. However, their application to Prognostics and Health Management (PHM) remains constrained by the limited uncertainty quantification (UQ) capabilities.

Two-dimensional Laplace-transformed power series solution for solute transport in a radially convergent flow field [PDF]

Advances in Water Resources, 2003
This paper presents an analytical solution for two-dimensional non-axisymmetric solute transport in a radially convergent flow field. We applied a Laplace-transformed power series (LTPS) technique to solve the two-dimensional advection-dispersion equation in cylindrical coordinates.

ParamNet: A Physics‐Guided Deep Learning Framework for Intelligent Self‐Inversion of Vacuum Optical Levitation Systems

Advanced Intelligent Systems, EarlyView.
A physics‐guided deep learning framework, ParamNet, is introduced for the intelligent self‐inversion of vacuum optical tweezers. By fuzing dual‐branch time–frequency features with physical dynamical constraints, it achieves high‐accuracy calibration of trap parameters from short‐window, low‐frequency trajectories, outperforming traditional methods ...

The Conservative and Efficient Numerical Method of 2-D and 3-D Fractional Nonlinear Schrödinger Equation Using Fast Cosine Transform

Mathematics
This paper introduces a novel approach employing the fast cosine transform to tackle the 2-D and 3-D fractional nonlinear Schrödinger equation (fNLSE). The fractional Laplace operator under homogeneous Neumann boundary conditions is first defined through

Complex Dispersion Relation Recovery from 2D Periodic Resonant Systems of Finite Size

Applied Sciences, 2019
The complex dispersion relations along the main symmetry directions of two-dimensional finite size periodic arrangements of resonant or non-resonant scatterers are recovered by using an extension of the SLaTCoW (Spatial LAplace Transform for COmplex ...

Nanodiamonds as Bioactive Platforms to Modulate Microbial, Mammalian, and Vertebrate Systems

Advanced NanoBiomed Research, EarlyView.
Nanodiamonds (NDs) are biocompatible and antibacterial nanomaterials that support mammalian cell growth while inhibiting bacterial pathogens. NDs showed strong antibacterial activity, with Escherichia coli being more sensitive than Staphylococcus aureus. At 10 mg/mL, both bacteria exhibited ~8% viability.
