Traditional DBSMs are suited for applications in which the structure, meaning and contents of the database, as well as the questions to be asked are already well understood. There is, however, a class of applications that we will collectively refer to as Interactive Data Exploration (IDE) applications, in which this is not the case. IDE is a key ingredient(More)
We present a new interactive data exploration approach, called Semantic Windows (SW), in which users query for multidimensional "windows" of interest via standard DBMS-style queries enhanced with exploration constructs. Users can specify SWs using (i) shape-based properties, e.g., "identify all 3-by-3 windows", as well as (ii) content-based properties,(More)
We present a new system, called Searchlight, that uniquely integrates constraint solving and data management techniques. It allows Constraint Programming (CP) machinery to run efficiently inside a DBMS without the need to extract, transform and move the data. This marriage concurrently offers the rich expressiveness and efficiency of constraint-based search(More)
We present a native XML database management system, Sedna, which is implemented from scratch as a full-featured database management system for storing large amounts of XML data. We believe that the key contribution of this system is an improved schema-based clustering storage strategy efficient for both XML querying and updating, and powered by a novel(More)
The analysis of biotic diversity using pictographs has shown various changes after long-term deforestation and under short-term disturbance of forest habitats. The biomass of small mammals was similar in all types of forest habitats; it was higher in meadows and dropped in the young (9-year) forest in the former field. The total biomass of settled and(More)
Distribution is a well-known solution to increase performance and provide load balancing in case you need optimal resource utilization. Together with replication it also allows improved reliability, accessibility and fault-tolerance. However since the amount of data is large there is a problem of maintaining meta-information about distribution and finding(More)
The behavior of three common shrew species was compared in a test of pairwise placement in a neutral territory (10 min) for various population densities in natural habitats and for animals kept isolated or in groups in open-air cage conditions. The behavior of the animals captured in nature was considered as the norm. We considered total number of social(More)
Searchlight enables search and exploration of large, multi-dimensional data sets interactively. It allows users to explore by specifying rich constraints for the "objects" they are interested in identifying. Constraints can express a variety of properties, including a shape of the object (e.g., a waveform interval of length 10-100ms), its aggregate(More)
A new method for quantitative study of small mammals swimming across water obstacles was developed. A line of 25 traps was installed on either poles or boards (“rafts”) with anchors at a distance of 20–25 m from the bank and with 10-m distances between the items. The study was performed upstream along the Ilych River in August 2013. A total of 300 trap/day(More)
Genourbanology (the synthesis of system ecology and population genetics) is a new scientific and practical school of thought, founded and developed by the authors. The task of genourbanology consists in studying the genetic parameters and laws of stability conservation of ecosystems and ecosystem restoration in anthropogenic and, in particular, urbanized(More)
