Morphological adaptations of cervical vertebrae in plunge‐diving sulids

The Anatomical Record, EarlyView.
Abstract Foraging strategy frequently drives morphological diversification in birds. The plunge‐diving behavior of certain species makes the functional and ecological trade‐offs of variation in cervical vertebrae an especially intriguing question. This study compares cervical vertebrae across five plunge‐diving species and two non‐plunge‐diving species,

Mild Hydrothermal Stabilization: An Innovative Technology for Improving Whole‐Grain Rice Quality in West Africa and Elsewhere

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Whole‐grain (brown) rice has superior nutritional quality but is prone to rancidity, primarily caused by endogenous lipases and oxidases. This study evaluated mild hydrothermal stabilization (MHS), comprising grain surface wetting, followed by short‐duration atmospheric‐pressure steaming, applied to two West African ...

Expansion versus intensification: oxygen-volume distribution shapes contrasting OMZ responses to deoxygenation

Environmental Research Letters
Ocean deoxygenation is driving widespread changes in major oxygen minimum zones (OMZs), yet the mechanisms underlying their contrasting responses to similar forcing remain poorly understood.

B, N‐Co Doped Porous Carbon Nanotubes Supported Cu Single Atoms and B‐Doped Cu Nanoparticles for High‐Performance Electrocatalytic NO3RR and Zn‐Nitrate Batteries

Carbon Energy, EarlyView.
The ToC image shows a porous B, N‐doped carbon nanotube decorated with B‐doped Cu nanoparticles for nitrate‐to‐ammonia conversion. The unique structure enhances charge transport, promotes the adsorption and activation of key intermediates, alters the rate‐determining step, suppresses hydrogen evolution, and improves NH3 yield and Faradaic efficiency ...

Central Trajectories [PDF]

, 2017
An important task in trajectory analysis is clustering. The results of a clustering are often summarized by a single representative trajectory and an associated size of each cluster. We study the problem of computing a suitable representative of a set of
