Higher-order sub-Poissonian-like nonclassical fields: Theoretical and experimental comparison
, 2017 Criteria defining higher-order sub-Poissonian-like fields are given using five different quantities: moments of (I) integrated intensity, (II) photon number, (III) integrated-intensity fluctuation, (IV) photon-number fluctuation, and (V) elements of ...

A generalized integrated population model to estimate greater sage‐grouse population dynamics
Ecosphere, 2016 For species of conservation concern, assessing population dynamics consistently across different populations is of paramount importance to effective conservation and restoration planning.

Human-Wildlife Interactions, 2017 Historical impacts from oil and gas development to greater sage-grouse (Centrocercus urophasianus) habitat are well-documented in some areas of Wyoming, in particular within natural gas development fields, such as the Powder River Basin and JonahPinedale.

Obstructions to combinatorial formulas for plethysm
, 2018 Motivated by questions of Mulmuley and Stanley we investigate quasi-polynomials arising in formulas for plethysm. We demonstrate, on the examples of $S^3(S^k)$ and $S^k(S^3)$, that these need not be counting functions of inhomogeneous polytopes of ...

Noise reduction in photon counting by exploiting spatial correlations
, 2017 Joint photocount distributions of a weak twin beam acquired by an iCCD camera are analyzed with respect to the beam spatial correlations. A method for extracting these correlations from the experimental joint photocount distributions is suggested using a

Avian Conservation and Ecology, 2020 Monitoring population response to conservation actions, such as habitat management, is critical to evaluate conservation outcomes. Greater Sage-Grouse (Centrocercus urophasianus) has been the recipient of substantial recent conservation efforts in North ...

Comparison between lek counts and bioacoustic recording for monitoring Western Capercaillie (Tetrao urogallus L.) [PDF]
Journal of Ornithology, 2019 Bioacoustics is the study of animal sounds. The importance of bioacoustics for biological research and the survey and monitoring of bird populations is becoming increasingly recognized. This is particularly the case for the capture of long-term data on rare species that are prone to disturbance or are otherwise difficult to survey.

European Journal of Social Psychology, EarlyView.ABSTRACT The atrocities committed during the Nazi era still affect Germany's image in the world and Germans' feelings about their country's past. Herein, we investigate how historical propaganda images glorifying Adolf Hitler influence these feelings. Prior scholars have raised concerns that such materials might communicate distorted images of the past

Wildlife Biology, EarlyView.The shift to ‘close to nature forestry' as the dominating forestry regime in western‐European forests has resulted in increasing timber volume and denser forests with negative effects on photophilic species. Hence, there is an increasing focus on active habitat management measures to support these species.

Ecosphere, 2016 Species conservation efforts often use short‐term studies that fail to identify the vital rates that contribute most to population growth. Although the greater sage‐grouse (Centrocercus urophasianus; sage‐grouse) is a candidate for protection under the U.
