The impact of accretion disk winds on the X-ray spectrum of AGN: Part 1 - XSCORT
, 2007 (abridged) The accretion disk in AGN is expected to produce strong outflows, in particular a UV-line driven wind. Despite providing a good fit to the data, current spectral models of the X-ray spectrum of AGN observed through an accretion disk wind are ...

Hunting method affects cortisol levels in harvested mountain hares (Lepus timidus)
Wildlife Biology, EarlyView.The direct effects of hunting on hunted individuals and populations have been well known for a long time. However, recently there has also been an increased focus on the indirect, non‐lethal effects of hunting. When approached by a possible threat such as a predator, the prey releases various stress hormones into the bloodstream.

Assessing habitat suitability for black grouse broods at the bioregional scale
Wildlife Biology, EarlyView.The black grouse Lyrurus tetrix, a galliform species emblematic of the European Alps, is currently threatened by habitat change, particularly given the closure of heathland linked to the rising tree line at higher altitudes. The presence of heathlands in good ecological condition is, however, imperative for the species' reproduction.

Vog: Using Volcanic Eruptions to Estimate the Health Costs of Particulates
The Economic Journal, EarlyView., 2018 The negative consequences of long‐term exposure to particulate pollution are well established but a number of studies find no effect of short‐term exposure on health outcomes. The high correlation of industrial pollutants complicates the estimation of the impact of individual pollutants on health.

Impact of ski run construction on atypical channel head development
Science of The Total Environment, 2019 The development of ski infrastructure in mountainous areas has a significant impact on the development of erosion landforms and modification of existing landforms on slopes. The main purpose of our study was to determine the effects of ski run construction and artificial snowmaking on the development of channel heads and drainage lines as well as ...

Monitoring wildlife using long‐endurance solar‐electric UAVs
Wildlife Biology, EarlyView.This report discusses the effectiveness of using small solar‐electric UAV (uncrewed aerial vehicles) for aerial wildlife monitoring. We review four years of aerial wildlife monitoring missions using a 5.5‐m wingspan, solar‐electric UAV that was equipped with a gimballed IR/RGB camera.

Species composition on reclaimed ski runs compared with unseeded areas [PDF]
Journal of Range Management, 2001 The cover of native and non-native introduced plants was compared between seeded (reclaimed) ski runs and adjacent or nearby unseeded (control) areas at a managed ski area in northern Arizona to determine the potential effects of revegetation efforts on plant species composition of the area. Although vegetative cover was similar, plant species richness

Probing the distance and morphology of the Large Magellanic Cloud with RR Lyrae stars [PDF]
, 2014 We present a Bayesian analysis of the distances to 15,040 Large Magellanic Cloud (LMC) RR Lyrae stars using $V$- and $I$-band light curves from the Optical Gravitational Lensing Experiment, in combination with new $z$-band observations from the Dark ...

3H and 3He calculations without angular momentum decomposition
, 2018 Results for the three nucleon (3N) bound state carried out using the "three dimensional" (3D) formalism are presented. In this approach calculations are performed without the use of angular momentum decomposition and instead rely directly on the 3D ...
