$γ$-deepDSM for interface reconstruction: operator learning and a Learning-Automated FEM package [PDF]

arXiv
In this work, we propose an Operator Learning (OpL) method for solving boundary value inverse problems in partial differential equations (PDEs), focusing on recovering diffusion coefficients from boundary data. Inspired by the classical Direct Sampling Method (DSM), our operator learner, named $\gamma$-deepDSM, has two key components: (1) a data ...

Robustly Repeatable, Permeable, and Multi‐Axially Stretchable, Adhesive Bioelectronics With Super‐adaptive Conductive Suction Cups for Continuously Deformable Biosurfaces

Advanced Science, EarlyView.
It is presented bioelectronics that exhibit exceptional adaptability to dynamic skin surfaces through an integrated structural and material design. These omnidirectionally stretchable, skin‐compliant, mechanically robust, and permeably biocompatible kirigami‐based devices minimize skin irritation and conductivity loss and offer new insights for the ...

The Tempered Finite Element Method [PDF]

arXiv
In this paper, we propose a new approach -- the Tempered Finite Element Method (TFEM) -- that extends the Finite Element Method (FEM) to classes of meshes that include zero-measure or nearly degenerate elements for which standard FEM approaches do not allow convergence.

Single‐Pixel Infrared Miniaturized Spectrometer Enabled by Ultra‐Broadband Reconfigurable Photodetection

Advanced Science, EarlyView.
A near‐infrared tunable micro‐spectrometer is achieved by integrating a PbS photodetection unit and a light modulation unit based on liquid crystal tuned optical resonances, demonstrating a wavelength tuning range exceeding 850 nm. This micro‐spectrometer shows high fidelity in spectral reconstruction and is also successfully applied to plastic sorting,

Options to improve the carbon balance of the harvested wood products sector in four EU countries

GCB Bioenergy
Harvested wood products (HWP) may contribute to climate change mitigation by storing carbon and by replacing energy‐intensive materials and fossil energy, reducing greenhouse gas (GHG) emissions.

Steady and transient thermal stress analysis using a polygonal finite element method [PDF]

arXiv
While the finite element method (FEM) has been widely used for thermal stress problems, it faces challenges in handling complex geometries, non-matching meshes, and achieving computational efficiency. To address these limitations, this study proposes an N-sides finite element method (NS-FEM) for solving steady-state and transient thermal stress ...
