Vortex Splitting in Subcritical Nonlinear Schrodinger Equation

, 2008
Vortices and axisymmetric vortex rings are considered in the framework of the subcritical nonlinear Schrodinger equations. The higher order nonlinearity present in such systems models many-body interactions in superfluid systems and allows one to study ...

Geomorphic Effectiveness of an Extreme Flood in a Mountain River: Evidence From Pre‐ and Post‐Event Surveys in a Subtropical Region of Southern Brazil

Hydrological Processes, Volume 40, Issue 5, May 2026.
The extreme flooding of April 2024 caused a complete “geomorphic reset”, resulting in a 24% widening of the channel and a transition to critical or supercritical flow regimes. The energy of the event broke through the stable armouring layer, reducing the armouring ratio from 7.9 to 4.9 and intensely removing fine sediments from the subsurface.

Subcritical versus supercritical transition to turbulence in curved pipes

, 2015
Transition to turbulence in straight pipes occurs in spite of the linear stability of the laminar Hagen--Poiseuille flow if the amplitude of flow perturbations as well as the Reynolds number exceed a minimum threshold (subcritical transition).

Potential of solid‐state microwaves in lab‐scale chemical‐process development

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 5, Page 1077-1093, May 2026.
Abstract BACKGROUND The integration of a solid‐state microwave (MW) generator into a newly designed, versatile MW reactor ensures improved energy efficiency, precise process control and broader application potential. In its most particular feature, the device supports the modification of dielectric‐radiation orientation and can be operated under ...

Sample Preparation and Separation of Lignans by Liquid Chromatography

Journal of Separation Science, Volume 49, Issue 5, May 2026.
ABSTRACT Lignans are important phytochemicals found mostly in the resins of coniferous trees, but are also introduced into human diets through foods such as sesame seeds and extra‐virgin olive oil. They are pharmacologically interesting mainly because of their antioxidant activities, and they have also been shown to have cytotoxic and antimicrobial ...

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

River Research and Applications, Volume 42, Issue 4, Page 886-900, May 2026.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.

Software to Support Remote Sensing of River Discharge Based on Critical Flow Theory

River Research and Applications, Volume 42, Issue 4, Page 915-928, May 2026.
ABSTRACT Water resource management requires accurate observations of streamflow but standard field methods for measuring river discharge ( Q ) can be costly and hazardous for equipment and personnel. Remote sensing has become a viable alternative, but many image‐based techniques require field data for calibration, and depth and velocity can seldom be ...

Modeling of water infiltration in hydrophobic‐over‐wettable two‐layer columns

Soil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract This paper presents a new piecewise model for simulating one‐dimensional infiltration curves in two‐layer finite columns consisting of a hydrophobic layer overlaying wettable soil. The model combines a physics‐based equation for infiltration in water‐repellent substrates with an analytical framework for ponded conditions.

Great Meteor Seamount Circulation Revisited: Insights Into Cold‐Water Coral Habitat Potential

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Seamounts play a crucial role in shaping deep‐sea ecosystem structure, influencing ocean circulation, enhancing biological productivity, and supporting diverse marine life. The Great Meteor Seamount (GMS), is the largest seamount in the North Atlantic and a key ecological feature in the regional network of the Protected Areas of the Azores ...
