Methods for Bayesian power spectrum inference with galaxy surveys

, 2013
We derive and implement a full Bayesian large scale structure inference method aiming at precision recovery of the cosmological power spectrum from galaxy redshift surveys.

Reef Fish Survey Techniques: Assessing the Potential for Standardizing Methodologies. [PDF]

PLoS ONE, 2016
Dramatic changes in populations of fishes living on coral reefs have been documented globally and, in response, the research community has initiated efforts to assess and monitor reef fish assemblages.

Galaxy 2-Point Covariance Matrix Estimation for Next Generation Surveys [PDF]

, 2017
We perform a detailed analysis of the covariance matrix of the spherically averaged galaxy power spectrum and present a new, practical method for estimating this within an arbitrary survey without the need for running mock galaxy simulations that cover ...

Relative occurrence of the family Kalotermitidae (Isoptera) under different termite sampling methods

Sociobiology, 2018
The termite family Kalotermitidae constitutes a wood-nesting termite family that accounts for about 15% of all extant termite species. In recent decades, field studies have been carried out to assess termite diversity in various wooded habitats and ...

Identifying obstacles preventing the uptake of tunnel handling methods for laboratory mice: An international thematic survey.

PLoS ONE, 2020
Handling of laboratory mice is essential for experiments and husbandry, but handling can increase anxiety in mice, compromising their welfare and potentially reducing replicability between studies.

Employment Status in the United States and Use of Long-Acting Reversible Contraception or Moderately Effective Contraception before and after the Affordable Care Act: National Survey of Family Growth 2006–2010 and 2015–2017

Preventive Medicine Reports, 2023
Employment status has been previously associated with contraceptive use among women of reproductive age. We assessed the association between employment status and method of contraception among US women of reproductive age, before and after the ...

Acoustic evaluation of wood quality with a non-destructive method in standing trees: a first survey in Italy

iForest - Biogeosciences and Forestry, 2017
Research and development efforts are currently underway worldwide to examine the potential use of a wide range of non-destructive technologies (NDT) for evaluating wood and wood-based materials, from the assessment of standing trees to in-place ...

The International Continence Society (ICS) survey on intermittent catheterization and global practices with regard to the reuse of catheters

Continence, 2023
Objective:: To survey members of the International Continence Society (ICS) for exploring global differences in practices with regard to intermittent catheterization (IC) and reuse of catheters in the neuro-urological patient.

Calibration biases in measurements of weak lensing

, 2011
As recently shown by Viola et al., the common (KSB) method for measuring weak gravitational shear creates a non-linear relation between the measured and the true shear of objects. We investigate here what effect such a non-linear calibration relation may

Bayesian inference from photometric redshift surveys [PDF]

, 2011
We show how to enhance the redshift accuracy of surveys consisting of tracers with highly uncertain positions along the line of sight. Photometric surveys with redshift uncertainty delta_z ~ 0.03 can yield final redshift uncertainties of delta_z_f ~ 0 ...
