Urban delineation through a prism of intraday commute patterns.

Introduction: Urban mobility patterns are crucial for effective urban and transportation planning. This study investigates the dynamics of urban mobility in Brno, Czech Republic, utilizing the rich dataset provided by passive mobile phone data. Understanding these patterns is essential for optimizing infrastructure and planning strategies.

Unraveling the Central Role of Sulfur-Oxidizing LMS in Industrial Bioprocessing of Gold-Bearing Sulfide Concentrates.

LMS is an acidophile isolated from industrial bioreactors during the processing of the gold-bearing pyrite-arsenopyrite concentrate at 38-42 °C. Most strains of this species are obligate organoheterotrophs that do not use ferrous iron or reduced sulfur compounds as energy sources. However, the LMS strain was identified as one of the predominant sulfur oxidizers in acidophilic microbial consortia.

The Resistance of to Oxidative, Genotoxic, Proteotoxic, Osmotic Stress, Infection, and Starvation Depends on Age According to the Stress Factor.

We studied how aging affects the ability of to tolerate various types of stress factors. Data were obtained on the resistance of to oxidative and genotoxic (separately paraquat, Fe, Cu, and Zn ions), proteotoxic (hyperthermia, Cd ions), and osmotic (NaCl) stresses, starvation, and infection with the pathological fungus at different ages. In all cases, we observed a strong negative correlation between age and stress tolerance.

The Influence of Chromosomal Environment on X-Linked Gene Expression in Drosophila melanogaster.

Sex chromosomes often differ from autosomes with respect to their gene expression and regulation. In Drosophila melanogaster, X-linked genes are dosage compensated by having their expression upregulated in the male soma, a process mediated by the X-chromosome-specific binding of the dosage compensation complex (DCC). Previous studies of X-linked gene expression found a negative correlation between a gene's male-to-female expression ratio and its distance to the nearest DCC binding site in somatic tissues, including head and brain, which suggests that dosage compensation influences sex-biased gene expression.

Quantifying segregation in an integrated urban physical-social space.

Our knowledge of how cities bring together different social classes is still limited. Much effort has been devoted to investigating residential segregation, mostly over well-defined social groups (e.g.
