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

open access: yesBiological Reviews, EarlyView.
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.

EnKF and expectation‐maximization based parameter estimation of a convective gravity‐wave parameterization using Strateole 2 constant‐level balloon data

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
An offline methodology is applied to estimate parameters of a convective gravity‐wave scheme using momentum flux (MF) observations from constant‐level balloons (left panels: pdfs of east and west MFs in green from observations and black from EnKF). The approach integrates an ensemble Kalman filter with an expectation‐maximization algorithm and permits ...

Update on the Pathophysiology, Aetiology and Management of Central Sleep Apnoea

open access: yesRespirology, EarlyView.
ABSTRACT Central sleep apnoea (CSA) of the periodic breathing type occurs during the transition between wakefulness and stage 1 and 2 non‐REM sleep. In adults at sea level, it occurs most commonly due to advanced heart failure (HF) or chronic opioid use and in ~5% of obstructive sleep apnoea patients initiating CPAP.

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

open access: yesSymbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We
