Comparing Populations in Data Involving Spatial Information

Methods for Comparing Correlations Involving Left-Censored Laboratory Data

1. Introduction In biomedical research, left-censored laboratory data is common. In infectious disease studies, for example, assays for quantification of viral concentration, e.g. human immunodeficiency virus type 1 (HIV-1), hepatitis C (HCV), cytomegalovirus, or human papilloma virus, are subject to lower limits of detection and quantification. Over the past several years, it has become increa...

Bayesian Prediction in Spatial Data Analysis

Models for spatial information encoding in neuronal populations

The work described here has the goal of providing mathematical models for important spatial information processing mechanisms in the brain. Two original models were developed targeting two core mechanisms: one dedicated to the phase precession effect and the other to the formation of hexagonal firing patterns of grid cells. Both mechanisms are embedded on the general problem of spatial informat...

Spatial data usability in the Polish Spatial Information System

The paper presents the core concepts of the Polish Spatial Information System, reflecting the results of investigations performed within the framework of the research project conducted at the Institute of Geodesy and Cartography. The architecture of the Polish Spatial Data Infrastructure with regard to data flow and data access is presented. Describing the System the author stresses the importa...
