: The Author in the Text State (Non-genre Autobiographies by Alta Vášová) [PDF]

open access: yesSlovenska Literatura, 2015
In the mid 1990s Alta Vášová returned to her literary roots. The paper deals with the expert reading, analysis of and comments on the proses that she included in her book titled Ostrovy nepamäti (The Islands of Non-Memory, 2008) overlapping with her ...

On the Optical Spectrum of 89 Her

open access: yesOpen Astronomy, 2011
The high resolution spectra of a post-AGB candidate, binary system 89 Her, were analysed for the chemical composition. The star was found to be metal deficient with [Fe/H] = -0.50±0.20. No enhancement of s-process elements was found.

Model atmospheres of irradiated exoplanets: The influence of stellar parameters, metallicity, and the C/O ratio

open access: yes, 2015
Many parameters constraining the spectral appearance of exoplanets are still poorly understood. We therefore study the properties of irradiated exoplanet atmospheres over a wide parameter range including metallicity, C/O ratio and host spectral type.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Models of magnetized neutron star atmospheres: thin atmospheres and partially ionized hydrogen atmospheres with vacuum polarization

open access: yes, 2009
Observed X-ray spectra of some isolated magnetized neutron stars display absorption features, sometimes interpreted as ion cyclotron lines. Modeling the observed spectra is necessary to check this hypothesis and to evaluate neutron star parameters.We ...

Dust cloud evolution in sub-stellar atmospheres via plasma deposition and plasma sputtering [PDF]

open access: yes, 2017
Context. In contemporary sub-stellar model atmospheres, dust growth occurs through neutral gas-phase surface chemistry. Recently, there has been a growing body of theoretical and observational evidence suggesting that ionisation processes can also occur.

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Stark Broadening of In III Lines in Astrophysical and Laboratory Plasma

open access: yesOpen Astronomy, 2011
In the deeper layers of hot stellar photospheres the Stark widths of spectral lines can be comparable and even larger than the thermal Doppler widths.

The Climate of Spaces. On Architecture, Atmospheres and Time

open access: yesESPES, 2023
This paper discusses the concept of climate in relation to architectural space. By elaborating on the notion of atmosphere, that today permeates a wide range of architectural research, I intend to expand its relevance by outlining a relationship between ...

The Atmospheric Signatures of Super-Earths: How to Distinguish Between Hydrogen-Rich and Hydrogen-Poor Atmospheres

open access: yes, 2008
Extrasolar super-Earths (1-10 M$_{\earth}$) are likely to exist with a wide range of atmospheres. Some super-Earths may be able to retain massive hydrogen-rich atmospheres.
