Spatial correlation and breast cancer risk [PDF]

open access: yesBiomedical Physics & Engineering Express, 2019
Abstract We present a novel method for evaluating local spatial correlation structure in two-dimensional (2D) mammograms and evaluate its capability for risk prediction as one possible application. Two matched case-control studies were analyzed.

Spatial distribution of precipitation in Lithuania

open access: yesMokslas: Lietuvos Ateitis, 2011
Analysis is based on a 36-year record (1971–2006) of daily precipitation at 17 meteorological stations throughout Lithuania. The obtained data was used to investigate the spatial properties of the precipitation fields of monthly decadals (10-days).
