Abstract. Recently, the interest has been focused on dynamic applications with geographic reference. These applications are commonly called as spatio-temporal applications and examine phenomena, which occur in specific geographical regions and change over time. In addition, data collected to model and analyze a phenomenon are accompanied with uncertainty. Current GIS technology turns out to be ...

Geographers are increasingly adopting visualization methods for exploring spatial data and generating hypotheses. Data exploration is not limited to the examination of original attribute data, but can be applied at different stages of geographic information processing. Multi-criteria evaluation is a simple yet powerful data processing technique for decision support using geographic information ...

Visualization of maps to explore relevant geographic areas is one of the common practices in spatial decision scenarios. However visualizing geographic distribution with multidimensional criteria becomes a nontrivial setup in the conventional point based map space. In this work we present a novel method to generalize from point data to spatial distributions, captivating on the swarm intelligenc...

A survey of entomopathogenic nematodes was conducted in the north Pacific (Guanacaste Conservation Area) and southeast Caribbean (Gandoca-Manzanillo Natural Refuge) regions of Costa Rica. Out of a total of 41 soil samples, 5 were positive for entomopathogenic nematodes (20.5%), with 3 (12.3%) containing Steinernema and 2 (8.2%) Heterorhabditis isolates. Morphological and molecular studies were ...

are measured on people who live within defined geographic regions. The measurements are then clustered within regions at each time point, but also comprise longitudinal measurements on each person across time. These data might be expected to have two potential sources of correlation, due to the similarity of measurements within and between the people in a region across time. While the former ex...

Background: Particulate matter pollution has become a growing health concern over the past few decades globally. The problem is especially evident in China, where particulate matter levels prior to 2013 are publically unavailable. We conducted a systematic review of scientific literature that reported fine particulate matter (PM2.5) concentrations in different regions of China from 2005 to 2016...

BACKGROUND Non-tunneled (temporary) hemodialysis catheters (NTHCs) are the least-optimal initial vascular access for incident maintenance hemodialysis patients yet little is known about factors associated with NTHC use in this context. We sought to determine factors associated with NTHC use and examine regional and facility-level variation in NTHC use for incident maintenance hemodialysis patie...

We sampled vole populations in Ukraine with the dual goal of characterizing population diversity and of providing a biogeographic perspective to evaluate experimental designs used for previous studies. Our data indicate that genetic diversity in bank vole populations is widely variable across regions and that diversity estimates in contaminated sites are unremarkable compared to those in uncont...
