Soil Science Annual, 2018 Taking into account the fact that (a) measurement of the cation exchange capacity and base saturation is practically unavailable in the field, that formally makes impossible the reliable field classification of many soils, (b) base saturation is measured

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Nanographene‐Based Saturable Absorbers for Ultrafast Fiber Lasers [PDF]
Journal of Nanomaterials, 2014 The generation of femtosecond pulse laser in the erbium‐doped fiber laser system is presented by integrating of the nanographene‐based saturable absorbers (SAs). A simplified method of dispersed nanographene‐based SAs side‐polished fiber device with controllable polished length and depth was also developed.

The Ebers-Moll model for magnetic bipolar transistors [PDF]
, 2004 The equivalent electrical circuit of the Ebers-Moll type is introduced for magnetic bipolar transistors. In addition to conventional diodes and current sources, the new circuit comprises two novel elements due to spin-charge coupling.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Soils classified in the Arboretum Mlyňany, Slovakia
Folia Oecologica, 2018 Successful adaptation of introduced trees requires providing appropriate conditions for their growth and life. In this context, our study aim was a soil survey in the Arboretum Mlyňany, on the basis of which the soils could be classified.

On the simulation of infiltration- and saturation-excess runoff using radar-based rainfall estimates: Effects of algorithm uncertainty and pixel aggregation [PDF]
, 1998 The effects of uncertainty in radar-estimated precipitation input on simulated runoff generation from a medium-sized (100-km2) basin in northern Texas are investigated.
