Cosmological parameter estimation: methods [PDF]
Comptes Rendus. Physique, 2003 CMB anisotropy data could put powerful constraints on theories of the evolution of our Universe. Using the observations of the large number of CMB experiments, many studies have put constraints on cosmological parameters assuming different frameworks. Assuming for example inflationary paradigm, one can compute the confidence intervals on the different ...

A talus rock glacier in Nantlle Valley, North Wales
Journal of Quaternary Science, EarlyView.ABSTRACT Landforms comprising mixtures of fine and coarse sediment and deposited during late glacial times are ubiquitous in the British mountains. In many cases, their interpretation has often proved contentious; as a result, the non‐generic term discrete debris accumulations (DDA) has been used to describe them and, over the last 50 years, some have ...

Clustering and redshift-space distortions in QSO and galaxy surveys [PDF]
, 2006 In this thesis, we exploit the potential of existing QSO and galaxy surveys for investigating the nature of the large scale structure in the Universe. A detailed analysis of clustering and redshift- space distortions allows us to constrain cosmological ...

The BINGO/ABDUS Project: Forecast for Cosmological Parameters from a Mock Fast Radio Burst Survey
The Astrophysical JournalThere are various surveys that will provide excellent data to search for and localize fast radio bursts (FRBs). The BINGO project will be one such survey, and this collaboration has already estimated an FRB detection rate that the project will yield.

On the cosmological parameters
The Astrophysical Journal, 1985 A partir de l'equivalence masse-energie d'Einstein, on suggere une relation newtonienne simple concernant les principaux parametres cosmologiques qui correspond bien aux valeurs recemment obtenues par l ...

Past, present and future of local crop evolution
PLANTS, PEOPLE, PLANET, EarlyView.Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Testing the Standard Cosmological Model [PDF]
, 2011 This thesis exploits the wealth of information contained in the existing cosmological surveys, and demonstrates how the use of tools such as two-point statistics permit the extraction of such information.

Integrating multimodal data and machine learning for entrepreneurship research
Strategic Entrepreneurship Journal, EarlyView.Abstract Research Summary Extant research in neuroscience suggests that human perception is multimodal in nature—we model the world integrating diverse data sources such as sound, images, taste, and smell. Working in a dynamic environment, entrepreneurs are expected to draw on multimodal inputs in their decision making.

The atacama cosmology telescope: cosmological parameters from the 2008 power spectrum [PDF]
, 2011 We present cosmological parameters derived from the angular power spectrum of the cosmicmicrowave background (CMB) radiation observed at 148 GHz and 218 GHz over 296 deg² with the Atacama Cosmology Telescope (ACT) during its 2008 season.
