Diverging fluctuations in a spatial five-species cyclic dominance game [PDF]
Physical Review E 88, 022123 (2013), 2013 A five-species predator-prey model is studied on a square lattice where each species has two prey and two predators on the analogy to the Rock-Paper-Scissors-Lizard-Spock game. The evolution of the spatial distribution of species is governed by site exchange and invasion between the neighboring predator-prey pairs, where the cyclic symmetry can be ...

Pathogenicity and Virulence of Ebolaviruses with Species- and Variant-specificity
Virulence, 2021 Ebola virus (EBOV), belonging to the species Zaire ebolavirus in the genus Ebolavirus, causes a severe febrile illness in humans with case fatality rates (CFRs) up to 90%.

Phase Transition in Two Species Zero-Range Process [PDF]
J. Phys. A: Math. Gen. 36 (2003) L441-L447, 2003 We study a zero-range process with two species of interacting particles. We show that the steady state assumes a simple factorised form, provided the dynamics satisfy certain conditions, which we derive. The steady state exhibits a new mechanism of condensation transition wherein one species induces the condensation of the other.

Cultivation of Wild Species from Goniolimon genera: a Case Study
Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2008 During the period 1996-2001 three wild perennial Bulgarian plants belong to Plumbaginaceae family (Goniolimon tataricum Boiss., Goniolimon besserianum (Shut ex Reichenb.) and Goniolimon collinum (Griseb.)) were studied at the Floriculture Institute ...

Environ centrality reveals the tendency of indirect effects to homogenize the functional importance of species in ecosystems [PDF]
Fann, SL and SR Borrett. 2012. Environ centrality reveals the
tendency of indirect effects to homogenize the functional importance of
species in ecosystems. Journal of Theoretical Biology 294(7), 74-86, 2011 Ecologists and conservation biologists need to identify the relative importance of species to make sound management decisions and effectively allocate scarce resources. We introduce a new method, termed environ centrality, to determine the relative importance of a species in an ecosystem network with respect to ecosystem energy--matter exchange.

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia
FEBS Letters, EarlyView.This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

FEBS Letters, EarlyView.The glacier ice worm Mesenchytraeus solifugus survives year‐round at 0 °C. Its ATP6 subunit, which forms a regulatory component of the proton pore in mitochondrial ATP synthase, has a carboxy‐terminal extension not found in any other organism examined to date. Here, we show that fusion of this extension to the homologous AtpB protein in E. coli results

Quantifying the taxonomic diversity in real species communities [PDF]
J. Phys. A: Math. Theor. 41, 224012 (2008), 2006 We analyze several florae (collections of plant species populating specific areas) in different geographic and climatic regions. For every list of species we produce a taxonomic classification tree and we consider its statistical properties. We find that regardless of the geographical location, the climate and the environment all species collections ...

Functional variation among LPMOs revealed by the inhibitory effects of cyanide and buffer ions
FEBS Letters, EarlyView.This study addresses the inhibition of lytic polysaccharide monooxygenases (LPMOs) by cyanide and explains how and why the magnitude of observed inhibitory effects depends on the way LPMO reactions are setup and on the type of LPMO. Enzymes known as lytic polysaccharide monooxygenases (LPMOs) are mono‐copper polysaccharide‐degrading peroxygenases that ...

FEBS Letters, EarlyView.The NlpC_P60 superfamily of peptidases is recognised by its key role in bacterial cell wall homeostasis. Recently, studies have also described the involvement of NlpC_P60‐like enzymes in bacterial competitive mechanisms and pathogenesis across several lineages.
