Processing of these archives represents many challenges, among them the application of geoinformatic concepts and information technologies. The article presents the example of geo-referencing, crowdsourcing, and other computer-based technologies applied to the archival photographs of today-destroyed sites on the Czech – Bavarian border, where many villages, farm sites and monuments were destroyed in the 1950s or abandoned as a consequence of post-WWII development. In the situation of dramatically changing landscape and land use, historical photographs are an important source of documentation for both research and virtual reconstruction of disappeared places, landscape, and society.

While cytogenomic approaches try to compensate for this issue by virtual karyotyping, they rely on the quality of genome assemblies available. Recently, soft-masked genome assemblies combining costly and arduous long- and short-read sequencing and new generation assemblers became available for two teleost fish species, climbing perch (Anabas testudineus) and channel bull blenny (Cottoperca gobio). Soft-masking turns repetitive sequences in a genome assembly into lower case letters, leaving unique sequences in upper case. This enables investigators to assess the proportion of guanine and cytosine nucleotides (GC%) of transposable elements as an indicator of AT/GC homogenisation in fish. We have developed a new version of our Python tool Evan, which utilises chromosome-level genome assemblies and combines the profiles of GC% a...

The proposed model and algorithms allow the efficient and secure use of additional network resources connected to the functional network, in contrast to traditional approaches, when these resources are not available within a single computing node on an independent computing platform. Subsequently, innovative approaches have been developed to build high-load risk resilient distributed cluster software systems, which provides a significant increase in the total amount of effective processing of information flows of the node communication system as a whole. Therefore, the use of this approach is appropriate for distributed risk-tolerant software systems where rapid loss of information flo...

Prevalently German-settled villages were wholy or partly destroyed in the aftermath of WWII, with little remains left in situ and landscape transformed by subsequent forestation, military training and Vltava water reservoir system. The paper presents cooperation between IT and historians/archaeologists that aims to reconstruct lost landscape based on historical and archaeological records (esp. historical photographs) and using up-to-date reconstruction and IT methods (incl. LIDAR scanning, crowdsourcing, mapping, photogrametry, 3D modelling, 3D printing).

However, the available genomic data have not been exploited to confirm this viewpoint. In contrast, further misunderstandings in GC%, mostly of fish genomes, originated from a misapprehension of the current flood of data. Utilizing public databases, we calculated the GC% in animal genomes of three different, technically well-established fractions: DNA (entire genome), cDNA (complementary DNA), and cds (exons). Our results across chordates help set borders of GC% values that are still incorrect in literature and show: (i) fish in their immense diversity possess comparably GC-rich (or even GC-richer) genomes as higher vertebrates, and fish exons are GC-enriched among vertebrates; (ii) animal genomes generally show a GC-enrichment from the DNA, over cDNA, to the cds level (i.e., not on...

We have not been able to prove the hypothesis that conditional entropy of human languages and DNA are similar. However, it has been shown that conditional entropy of DNA apparently differs from conditional entropy of randomly generated text.
