A robust numerical method for the generation and propagation of periodic finite-amplitude internal waves in natural waters using high-accuracy simulations [PDF]

Nonlinear Processes in Geophysics
The design and implementation of boundary conditions for the robust generation and simulation of periodic finite-amplitude internal waves is examined in a quasi two-layer continuous stratification using a spectral-element-method-based incompressible flow

A Regional Model Comparison between MODPATH and MT3D of Groundwater Travel Time Distributions

Groundwater, EarlyView.
Abstract Groundwater quality changes in wells and streams lag behind changes to land use due to groundwater travel times. Two contaminant transport methods were compared to assess differences in their simulated travel time distributions (TTDs) to streams and wells in the Wisconsin Central Sands.

Automated path‐planning strategy for robotic inspection of underground utilities based on building information model

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract This paper proposes a fully automated end‐to‐end inspection‐path‐planning strategy for underground utilities, such as pipelines, based on building information modeling (BIM). An automatic extraction method is developed to process utility information from BIM models, using a registration step that pairs each pipeline with its corresponding ...

Progressive Oxygenation of the North Atlantic Subpolar Gyre

Journal of Geophysical Research: Oceans, Volume 130, Issue 11, November 2025.
Abstract The subpolar North Atlantic (SPNA) is one of the few regions where the deep ocean is in direct contact with the atmosphere, making it a key location for interior ocean ventilation through gas exchange. We use a novel observation‐based data product to analyze large‐scale patterns of the air‐sea flux of oxygen, finding a mean annual flux of 48.1

Numerical Analysis of Erosion Caused by Biomimetic Axial Fan Blade

Advances in Materials Science and Engineering, 2013
Damage caused by erosion has been reported in several industries for a wide range of situations. In the present work, a new method is presented to improve the erosion resistance of machine components by biomimetic method.

Advance in the assembly of the plant mitochondrial genomes using high‐throughput DNA sequencing data of total cellular DNAs

Plant Biotechnology Journal, Volume 23, Issue 11, Page 4944-4965, November 2025.
Summary The assembly of plant mitochondrial genomes presents unique challenges due to difficulties in isolating mitochondrial DNA (mtDNA) and plant mitochondrial genome characteristics, such as low interspecific conservation; sequence sharing among mitochondrial, nuclear and plastid DNAs; and complex structural variations.

GRACE‐FO and Future Satellite Gravity Missions Will Need to Account for Global Cloud Water Convergence

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 20, 28 October 2025.
Abstract Convective storms cause significant atmospheric and hydrological mass changes through the rapid accumulation of water vapor, cloud water, and heavy precipitation over hours or days. Gravity Recovery and Climate Experiment (GRACE) and GRACE‐Follow‐On (GRACE‐FO) gravity field solutions enable holistic monitoring of terrestrial water storage ...

Investigation of Fluid–Structure Interaction in Stenosed Bifurcated Arteries: Flow Dynamics and Conjugate Heat Transfer

Mathematics
Atherosclerosis, marked by elevated plaque formation, occurs due to stenosis, which narrows the arterial walls and alters the natural flow path. Previous research has shown that the likelihood of high-rupture stenosis can be linked to temperature ...
