A new look at a polar crown cavity as observed by SDO/AIA [PDF]
, 2011 Context. The Solar Dynamics Observatory (SDO) was launched in February 2010 and is now providing an unprecedented view of the solar activity at high spatial resolution and high cadence covering a broad range of temperature layers of the atmosphere ...

Volcanic eruptions and global ozone dynamics
International Journal of Remote Sensing, 1995 It is well known that heterogeneous chemistry plays a very important role in global ozone dynamics. A survey of new observations and numerical modelling results has been made to analyse the potential impact of volcanic eruptions on the stratospheric ozone layer in the context of the heterogeneous chemical reactions on surfaces of volcanically produced ...

Onset of a Large Ejective Solar Eruption from a Typical Coronal-Jet-Base Field Configuration
, 2017 Utilizing multiwavelength observations and magnetic field data from SDO/AIA, SDO/HMI, GOES and RHESSI, we investigate a large-scale ejective solar eruption of 2014 December 18 from active region NOAA 12241.

Charge structure in volcanic plumes: a comparison of plume properties predicted by an integral plume model to observations of volcanic lightning during the 2010 eruption of Eyjafjallajökull, Iceland [PDF]
, 2014 Cancer is a heterogeneous disease with different combinations of genetic alterations driving its development in different individuals. We introduce CoMEt, an algorithm to identify combinations of alterations that exhibit a pattern of mutual exclusivity ...

Understanding the plume dynamics of explosive super-eruptions [PDF]
Nature Communications, 2018 AbstractExplosive super-eruptions can erupt up to thousands of km3 of magma with extremely high mass flow rates (MFR). The plume dynamics of these super-eruptions are still poorly understood. To understand the processes operating in these plumes we used a fluid-dynamical model to simulate what happens at a range of MFR, from values generating intense ...

Multiwavelength Observations of an Eruptive Flare: Evidence for Blast Waves and Break-out
, 2013 Images of an east-limb flare on 3 November 2010 taken in the 131 \AA\ channel of the Atmospheric Imaging Assembly onboard the Solar Dynamics Observatory provide a convincing example of a long current sheet below an erupting plasmoid, as predicted by the ...

Wide‐Range Adaptive Metal Oxide for Hydrogen Sulfide Detection From Earth to Space‐Like Environments
Advanced Science, EarlyView.This work presents a gas sensing platform based on Cu‐doped SnO2 microspheres that operates reliably from ambient to space‐like conditions. The sensor maintains performance across vacuum and cryogenic environments, bypassing traditional oxygen‐mediated mechanisms, utilizing direct chemisorption and interfacial charge transfer.
