Unbiased Finite Element Mesh Delaunay Constrained Triangulation Applied to 2D Images with High Morphological Complexity Using Mathematical Morphology Tools Part 1: Binary Images

Computation
We propose a method for establishing a Constrained Delaunay Triangulation CDT applied to 2D binary images of high morphological complexity. A prerequisite for CDT is the unbiased definition of the Planar Straight-Line Graph PSLG, which must respect the ...

Long Unrest (2007–2025) at Laguna del Maule: Linking Strain Field and Seismicity From GNSS and Seismic Data

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The Laguna del Maule volcanic field in Chile has been uplifting at exceptional rates since 2007, offering a unique opportunity to examine the interplay between crustal deformation and magma dynamics. To understand this relationship, we integrate GNSS with local seismic observations from 2013 to 2024 to model the reservoir strain field ...

Non-negative mixed finite element formulations for a tensorial diffusion equation

, 2009
We consider the tensorial diffusion equation, and address the discrete maximum-minimum principle of mixed finite element formulations. In particular, we address non-negative solutions (which is a special case of the maximum-minimum principle) of mixed ...

Enhanced Recognition via Defect Engineered Amorphous Metal–Organic Framework for Sensitive and Stable Pesticide Biosensor

Advanced Science, Volume 13, Issue 7, 3 February 2026.
A defect‐engineered assembly strategy is reported for the in situ encapsulation of acetylcholinesterase (AChE) into amorphous MOF‐74, endowing the composite with superior catalytic activity and target recognition capability. Leveraging these structural advantages, a sensitive and stable biosensor is constructed for the detection of paraoxon pesticide ...

Spatiotemporal Statistical Downscaling for the Fusion of In-lake and Remote Sensing Data [PDF]

, 2018
This paper addresses the problem of fusing data from in-lake monitoring programmes with remote sensing data, through statistical downscaling. A Bayesian hierarchical model is developed, in order to fuse the in-lake and remote sensing data using ...

Mesh, Hydrodynamic Boundary, and Uncertainty Analysis of the 2D‐SWEs: Taking Numerical Simulation of River Networks as an Example

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Targeting the issues of insufficient predictive ability and inefficient computation in two‐dimensional shallow water equations (2D‐SWEs), this study deeply couples the mesh and hydrodynamic boundary, constructing multiple 2D hydrodynamic models (run 2,640 times).

Dot Symbol Auto-Filling Method for Complex Areas Considering Shape Features

ISPRS International Journal of Geo-Information, 2019
Filling dot maps with a regular pattern is a key step in visual representation of land use data. The traditional methods cannot adapt well to shape features of complex areas, leading to an unreasonable symbol arrangement in the inner region and area ...

A Novel Robust High‐Precision Ionospheric Delay Modeling for PPP‐RTK Using Crowdsourced Data

Space Weather, Volume 24, Issue 2, February 2026.
Abstract The performance of PPP‐RTK is critically dependent on the quality of ionospheric corrections derived from a reference network. While the proliferation of mass‐market Global Navigation Satellite System (GNSS) devices offers a promising crowdsourcing opportunity to densify or replace this infrastructure, it introduces the formidable challenge of
