Computational analysis to assess hemodynamic forces in descending thoracic aortic aneurysms

The Journal of Physiology, EarlyView.
Abstract figure legend Left: Pre‐processing. First, we perform the segmentation of the Computer Tomography angiorgraphy (angio‐CT) scans of a healthy patient, obtaining the surface of a healthy thoracic aorta with a Type III aortic arch. Then, we build nine ideal configurations with Descending Thoracic Aortic Aneurysm (DTAA), varying the aortic arch ...

Vortices and factorization

Reviews in Mathematical Physics
In this paper, we review applications of factorization methods to the problem of finding stationary point vortex patterns in two-dimensional fluid mechanics. Then we present a new class of patterns related to periodic analogs of Schrodinger operators from the “even” bi-spectral family.

Data‐Driven Emulation of Numerically Simulated Baltic Sea Surface Currents With a Deep Convolutional U‐Net: Explainability and Potential Forecast Skill

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Ocean models can represent surface circulation at kilometer scales, but their computational cost limits broad experimentation. We present DeepCUN, a deep convolutional encoder–decoder (U‐Net) that emulates daily mean Baltic Sea surface current components on a 1‐nautical‐mile grid.

Moisture Decomposition With Normal Modes in Global Data: Balanced and Unbalanced Components

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract Decompositions with normal modes have been useful for numerous purposes, such as theoretical understanding of balanced and unbalanced circulations, and applications to data assimilation. However, normal mode decompositions have typically been formulated for dry dynamics without moisture.

Tropical Pacific as a Pacemaker of Recent Decadal Anticyclonic Intensification Over the Barents–Kara Sea

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Under anthropogenic warming, a strengthened wintertime anticyclonic anomaly over the Barents–Kara Sea (BKS) has emerged as a hallmark of recent Arctic climate change. While local forcing from sea ice loss has been widely emphasized, the quantitative contribution of remote tropical forcing remains poorly constrained.

Track‐Dependent Links Between Tropical Cyclones and Extratropical Predictability in Physical and AI Models

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Global medium‐range weather forecasts suffer occasional failures (“busts”) linked to tropical cyclones (TCs). We investigate TC influences on extratropical predictability by comparing forecasts from a physics‐based model (ECMWF‐IFS) and an AI‐hybrid model (Google‐NGCM) initialized near TC genesis.

Regulatory Factors of the Morning Peak of Summer Regional Precipitation Events Over the Middle and Lower Yangtze River Basin, China

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The diurnal variation of regional precipitation events (RPE) over the Middle and Lower Yangtze River Basin (MLYRB) significantly affects human activities and serves as a key reference for weather forecasting. Here, the diurnal variation of summer RPE over MLYRB under two monsoonal synoptic types and their regulatory factors have been addressed.

Mechanisms of the QBO Influence on the Tropical Troposphere: Modulation by ENSO Conditions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The Quasi‐Biennial Oscillation (QBO) is the dominant mode of tropical stratospheric variability that can influence tropospheric circulation and convection. El Niño‐Southern Oscillation (ENSO), which is the primary source of interannual variability in the tropical troposphere, can modulate both the QBO and its impact on the tropical troposphere.

Research on the Internal Flow Difference between Peak and Valley Conditions of Water Jet Propulsion Pump during Working at Hump Region

Journal of Marine Science and Engineering
When we tested the water jet propulsion pump, we found that there were significant vibrations in the pump, especially at small flow points that deviated from the design conditions. The water jet propulsion pump is a mixed-flow pump with guide vane, which
