A conservative numerical scheme for the multilayer shallow‐water equations on unstructured meshes

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
An energy‐conserving scheme is derived for the multilayer shallow water model, making use of the direct connection between energy conservation and the skew symmetry of the Poisson bracket for the model. A new mechanism is proposed to prevent layer interface outcropping.

Automated extraction of right whale morphometric data from drone aerial photographs

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Aerial photogrammetry is a popular non‐invasive method for measuring marine mammal body size, body morphometrics, and body condition, but processing large datasets efficiently remains challenging. We developed a machine learning algorithm using Mask R‐CNN models to automatically measure body morphometrics of southern right whales from aerial ...

The Extremely Low Mechanical Force Generated by Nano‐Pulling Induces Global Changes in the Microtubule Network, Nuclear Morphology, and Chromatin Transcription in Neurons

open access: yesSmall, EarlyView.
Nano‐pulling induces stabilization, reorganization, and reorientation of the microtubule network. The nucleus of stretched cells experiences increased lateral tension, becomes more spherical, and develops surface grooves. At the level of gene expression regulation, changes in nuclear morphology induce global chromatin remodeling, leading to reduced ...

Single‐Atom Catalyst‐Integrated Porous Organic Polymers for High‐Performance Lithium‐Sulfur Batteries

open access: yesSmall, EarlyView.
Out‐of‐plane single‐atom catalysts are developed for Li‐S batteries to improve redox kinetics and mitigate LPS shuttling. A thianthrene‐based POP with a tetrathiocine linker is synthesized to anchor Pt single‐atom catalysts with both in‐plane and out‐of‐plane coordination, enhancing LPS adsorption and conversion in Li‐S batteries. Pt‐S─POP/rGO‐modified
