Legendary mathematician Paul Erdos liked to talk about the perfect proofs of mathematical theorems maintained by God. In [1], six different proofs are given to the infinity of prime numbers. Unlike mathematical proofs which are mentally reproducible objects, signal processing researchers can have an intimate discussion with God by creating computational algorithms which are experimentally repro...

During malignant transformation, cancer cells acquire genetic alterations that surmount the normal controls regulating proliferation and cell survival. High-resolution comparative genomic analyses reveal that genomic instability is a hallmark of cancer development and that cancer-causing mutations are only a tiny fraction of the genetic modifications, most of which are “bystander” mutations. Th...

Ultrafine particles (UFP, diameter < 100 nm) exposure has already been associated with adverse effects on human health. Spatial distribution of UFP is non-uniform; they concentrate in the vicinity of the source, e.g. traffic, because of their short lifespan. This work investigates spatial distribution of UFP in three areas in the Czech Republic with different traffic load: High traffic (Prague ...

forest roads are directions in natural habitats that used to transport wood products, secondary forest products and recreation. constructing forest roads causes trees clearing with specified width thus lead to direct or indirect changes in forest ecosystems and forest environment. this study aims to assess the changes of diversity and richness indices in main and secondary forest roads in a par...
