Dispersal, source and glass chemistry of a third tephra unit within Iceland's Settlement Layer

Boreas, EarlyView.
Tephra layers may be studied to understand the dynamics and sequence of past explosive volcanism. In Iceland, the distinctive Settlement Layer (AD ~877) underlies almost all archaeological evidence for the Norse Settlement and is preserved in soils across Iceland and as cryptotephra overseas.

Trans‐oceanic migration and wind utilization by Amur Falcons (Falco amurensis)

Ibis, EarlyView.
The Amur Falcon Falco amurensis performs one of the world's longest raptor migrations, involving a non‐stop crossing of the Indian Ocean of approximately 2800 km. While the existence of this route is known, the mechanistic details of wind exploitation and seasonal navigation remain to be fully elucidated.

Post‐flight assessment of the OSIRIS‐REx Sample Return Capsule (SRC) for organic and other potential contaminants

Meteoritics &Planetary Science, EarlyView.
Abstract Regolith samples from the carbonaceous asteroid Bennu were stowed and delivered to Earth in the OSIRIS‐REx spacecraft's Sample Return Capsule (SRC). We applied multiple analytical techniques to study the components of the post‐flight SRC, with a focus on assessing the conditions and any contaminants to which the Bennu samples were exposed ...

Investigating Buoyant Plume Dynamics Induced by Localized Fire‐Simulated Heating Over Plant Canopies Using LES

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Plume interaction with a forest canopy results in flow features distinct from those in grasslands. Here, we model the turbulence dynamics of a buoyant plume in a homogeneous plant canopy with a crosswind using Large‐Eddy Simulations. As the plume interacts with the crosswind, we observe increased vorticity at the windward and tilted hair‐pin ...

Flight of the dragons: a global review of migration in Odonata

Biological Reviews, Volume 101, Issue 5, Page 2134-2157, October 2026.
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.

Influence of Suspension Parameters on the Curve Passage Performance of Metro Vehicle under Crosswind in Mountain City

机车电传动, 2020
To investigate the influence of suspension parameters on the curve passage performance of metro vehicle under crosswind in mountain city, the targeted type-B vehicle dynamics model was established in the mountain city. The influence of the windward angle,

On the effects of crosswinds in tandem aerodynamics:An experimental and computational study

European Journal of Mechanics - B/Fluids, 2019
Aerodynamics has been an important research aspect in cycling science, with aerodynamic apparel and equipment, athlete postures, and race strategies all taking advantage of scientific aerodynamics knowledge. Crosswinds occur when cyclists travel at a non-zero angle to the direction of the wind.

Analysis of Low‐Level Windshear Cases at the Hong Kong International Airport Under Prevailing Easterly Wind Situations

Meteorological Applications, Volume 33, Issue 5, September/October 2026.
LIDARs are found to provide crucial data for capturing windshear features related to terrain, low‐level jet and synoptic forcing. Their glide‐path scan data are highly useful for constructing the headwind profiles, which are used to generate windshear alerts.

Analysis of crosswind aerodynamics for competitive hand-cycling

Journal of Wind Engineering and Industrial Aerodynamics, 2018
Competitive hand-cycling represents a unique case for cycling aerodynamics as the athletes are in a relatively aerodynamic position in comparison to traditional able-bodied cyclists. There are some aerodynamic similarities between both cycling disciplines, including wheel designs and helmets.
