Studying dawn-dusk asymmetries of Mercury's magnetotail using MHD-EPIC simulations

open access: yes, 2019
MESSENGER has observed a lot of dawn-dusk asymmetries in Mercury's magnetotail, such as the asymmetries of the cross-tail current sheet thickness and the occurrence of flux ropes, dipolarization events and energetic electron injections.

Delineating seasonal shifts in reindeer habitat and diet selection by integrating GPS telemetry and stable isotope analysis

open access: yesWildlife Biology, EarlyView.
Seasonal changes shape herbivore behaviour by altering forage availability and habitat conditions; however, few studies integrate diet and habitat selection data across temporal scales. This study uses seasonality as a unifying framework to combine fine‐scale GPS‐based habitat selection data with broader‐scale dietary information from stable isotope ...

Relation of electric field and particle precipitation in the polar cap region inferred from Akebono observations

open access: yesAntarctic Record, 1994
Akebono (EXOS-D) observations revealed that an electric field in the polar cap region was very irregular and an entire polar cap region was filled with many electron precipitation spikes when the interplanetary magnetic field (IMF) was directed northward.

JUMPSAT: Qualifying three equipments in one Cubesat mission [PDF]

open access: yes, 2013
We work on a student 3U Cubesat mission, called JUMPSAT, expected for 2017. This is a collaborative project involving both institutions (CNES, ONERA) and schools (ISAE, TELECOM Bretagne).

Pollination‐related plant traits under environmental changes: Seasonal and daily mismatches produce temporal constraints

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Pollination is a key tenet of ecosystem sustainability and food security, but it is threatened by climate change. While many studies investigated the response of plant‐pollination traits to temperature, few attempted multifactorial and integrative approaches with ...

Don’t Lose Your Heart to a Car. Extracorporeal Ejection of the Heart by Forceful Upward Thoraco-abdominal Blunt Trauma in Human and Animal.

open access: yesAlbanian Journal of Trauma and Emergency Surgery, 2020
The traumatic extracorporeal ejection of a beating heart has not been witnessed and reported in the literature previously, to our knowledge. Here we present two cases of vehicle accidents leading to this fatal injury, both in a rabbit and a human ...

Why is there more ionosphere in January than in July? The annual asymmetry in the F2-layer [PDF]

open access: yesAnnales Geophysicae, 2006
Adding together the northern and southern hemisphere values for pairs of stations, the combined peak electron density NmF2 is greater in December-January than in June–July. The same applies to the total height-integrated electron content.

Climate stability drives multidimensional nestedness of amphibian assemblages in a Chinese sky island system

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate
