Development of a 3D Human Colon Model Along with Bioelectronics for the Induction and Monitoring of Diseases. [PDF]
Adv Sci (Weinh)We present a functional three‐dimensional in‐vivo‐mimicking human colon (3D‐IVM‐HC) model engineered via Freeform Reversible Embedding of Suspended Hydrogels bioprinting with gelatin methacrylate (GelMA)/alginate hydrogels. This 3D non‐animal model replicates crypt‐like architectures, epithelial polarization, and stromal–tumor interactions, showing ...

Exceptional points in a passive strip waveguide. [PDF]
NanophotonicsAbstract Exceptional points (EPs) in non‐Hermitian systems have attracted significant interest due to their unique behaviors, including novel wave propagation and radiation. While EPs have been explored in various photonic systems, their integration into standard photonic platforms can expand their applicability to broader technological domains.

Computers and Geotechnics, 2021 This paper is concerned with a new prediction methodology for longitudinally invariant soil-structure interaction problems in elastodynamics. The method uses the finite-element method to model the structure, the boundary-element method to model the local soil surrounding the structure and the method of fundamental solutions to model the wave ...

Engineering Structures, 2021 Abstract Wave propagation in a longitudinally curved viscoelastic structure with a large or infinite cross section is a common problem frequently encountered. To study this problem, a coupled finite element method-perfectly matched layer (FEM-PML) modelling methodology based on a curved two-and-a-half-dimensional (2.5D) formulation is proposed in ...

Transverse Spurious Mode Compensation for AlN Lamb Wave Resonators
IEEE Access, 2019 Lamb wave modes with type I dispersion characteristics exhibit strong affinity toward multi transverse modes behavior above resonance frequency (fr) in the AlN Lamb wave resonators (LWRs), especially the high-transduction-efficiency modes: S0 and S1 mode.

INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2023 This paper presents an efficient method to predict underground railway-induced vibrations. The method uses the finite element method (FEM) to model the railway tunnel structure and the singular boundary method (SBM) to model the wave propagation in the surrounding soil.
