Power-Law Distributions in Empirical Data [PDF]
SIAM Review, 2007 Power-law distributions occur in many situations of scientific interest and have significant consequences for our understanding of natural and man-made phenomena. Unfortunately, the detection and characterization of power laws is complicated by the large

Parton distributions for the LHC run II [PDF]
, 2014 A bstractWe present NNPDF3.0, the first set of parton distribution functions (PDFs) determined with a methodology validated by a closure test. NNPDF3.0 uses a global dataset including HERA-II deep-inelastic inclusive cross-sections, the combined HERA ...

Diversity and Distributions: A journal of biological invasions and biodiversity, 2022 Human‐induced pressures such as deforestation cause anthropogenic range contractions (ARCs). Such contractions present dynamic distributions that may engender data misrepresentations within species distribution models.

Diversity and Distributions: A journal of biological invasions and biodiversity, 2022 Aggregated species occurrence data are increasingly accessible through public databases for the analysis of temporal trends in the geographic distributions of species. However, biases in these data present challenges for statistical inference.

Parton distributions for the LHC [PDF]
, 2007 We present updated leading-order, next-to-leading order and next-to-next-to-leading order parton distribution functions (“MSTW 2008”) determined from global analysis of hard-scattering data within the standard framework of leading-twist fixed-order ...

Forecasting species distributions: Correlation does not equal causation
Diversity and Distributions: A journal of biological invasions and biodiversity, 2022 Identifying the mechanisms influencing species' distributions is critical for accurate climate change forecasts. However, current approaches are limited by correlative models that cannot distinguish between direct and indirect effects.

Advances in Astronomy, Volume 2010, Issue 1, 2010., 2010 Recent and forthcoming advances in instrumentation, and giant new surveys, are creating astronomical data sets that are not amenable to the methods of analysis familiar to astronomers. Traditional methods are often inadequate not merely because of the size in bytes of the data sets, but also because of the complexity of modern data sets.

New generation of parton distributions with uncertainties from global QCD analysis [PDF]
, 2002 A new generation of parton distribution functions with increased precision and quantitative estimates of uncertainties is presented. This work signiflcantly extends previous CTEQ and other global analyses on two fronts: (i) a full treatment of available ...

Random graphs with arbitrary degree distributions and their applications. [PDF]
Physical review. E, Statistical, nonlinear, and soft matter physics, 2000 Recent work on the structure of social networks and the internet has focused attention on graphs with distributions of vertex degree that are significantly different from the Poisson degree distributions that have been widely studied in the past. In this

Diversity and Distributions: A journal of biological invasions and biodiversity, 2022 Species‐specific conservation strategies are frequently formulated based on species distribution maps, which are challenging to produce, especially at large spatial scales.
