Surface and lightning sources of nitrogen oxides over the United States: Magnitudes, chemical evolution, and outflow [PDF]

, 2007
We use observations from two aircraft during the ICARTT campaign over the eastern United States and North Atlantic during summer 2004, interpreted with a global 3-D model of tropospheric chemistry (GEOS-Chem) to test current understanding of regional ...

Natural disaster risk salience and the strategic appointment of directors with sustainability expertise

Journal of Financial Research, EarlyView.
Abstract This article examines how salient sustainability risks from near‐miss natural disasters influence board composition. Using a difference‐in‐differences design, I find that firms located in counties neighboring disaster‐affected areas significantly increase the presence of directors with sustainability expertise following the disaster.

Rapid postfire color shift in a Mediterranean lizard

Journal of Zoology, EarlyView.
We quantified dorsal luminosity and color composition of Psammodromus algirus in burned and adjacent unburned habitats at different times since fire. Lizards inhabiting recently burned areas displayed lighter dorsal coloration, particularly during the early stages of postfire succession, with the effect being more pronounced in larger individuals ...

Measurement and analysis of partial lightning currents in a head phantom

PLOS ONE, 2019
Direct lightning strikes to the human head can lead to various effects, ranging from burnings to death. The biological and physical mechanisms of a direct lightning strike in the human head are not well understood. The aim of this paper is to design an experimental setup to measure the spatial and temporal current distribution during a direct lightning

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 ...

Microspherules Formed by Lightning Strikes

Meteoritics &Planetary Science, EarlyView.
Abstract Natural microspherules are formed by high‐temperature processes and are present throughout the geologic record to the present day. We report the discovery of large numbers of microspherules recovered from a rock pavement in the Pilbara region, Western Australia.

Samplify: a versatile tool for image‐based segmentation and annotation of seed abortion phenotypes

New Phytologist, EarlyView.
Summary Automated seed phenotyping has wide applications in research and agriculture and relies on easy‐to‐use platforms and pipelines. Seed phenotyping in the model species Arabidopsis thaliana poses a significant challenge due to the large number of tiny seeds produced by individual plants, which are difficult to manually separate and count.
