Differences between two populations of Stipa krylovii in adaptive strategies: analysis of a three‐year reciprocal transplant experiment

Nordic Journal of Botany, EarlyView.
Understanding how the relative importance of local adaptation versus phenotypic plasticity varies across spatiotemporal scales is critical for explaining and predicting plant population dynamics. We conducted a three‐year reciprocal transplant experiment with the dominant grass Stipa krylovii between contrasting sites (wetter Xilinhot and drier ...

Study of the production mechanism of the eta meson by means of analysing power measurements

, 2006
Information about the production mechanism of the eta meson in proton-proton collisions can be inferred by confronting the experimental studies on the analysing power for the p(pol)p --> pp eta reaction with the theoretical predictions of this observable.

In-medium properties of mesons

EPJ Web of Conferences, 2017
In the project B.4, the modification of meson properties (mass, width) in a nuclear medium has been studied in photoproduction of mesons off nuclear targets.

The light scalar mesons as tetraquarks

Physics Letters B, 2016
We present a numerical solution of the four-quark Bethe–Salpeter equation for ground-state scalar tetraquarks with JPC=0++. We find that the four-body equation dynamically generates pseudoscalar-meson poles in the Bethe–Salpeter amplitude.

Inocybe alboaurantiaca (Inocybaceae), a new species from Asia

Nordic Journal of Botany, EarlyView.
A new Inocybe (Inocybaceae) species, Inocybe alboaurantiaca, is described and illustrated from Asia (Japan and Pakistan), based on morphological and phylogenetic analyses of the nrITS and nrLSU regions. Phylogenetically, the most closely related sequences belong to the current mainstream European concept of Inocybe fibrosa.

Decay constants and form factors of s-wave and p-wave mesons in the covariant light-front quark model

, 2011
We reanalyze the decay constants of s-wave and p-wave mesons and D, B ->M form factors, where M represents a pseudoscalar meson, a vector meson, a scalar meson, or an axial vector meson within a covariant light-front quark model.

Thermal energy of a charm-meson molecule in a pion gas

Journal of High Energy Physics
The thermal corrections to the propagator of a loosely bound charm-meson molecule in a pion gas are calculated to next-to-leading order in the heavy-meson expansion using a zero-range effective field theory.

There is only one set of the correct values of fF, fD and fS coupling constants in SU(3) invariant Lagrangian of the vector-meson-baryon interactions [PDF]

EPJ Web of Conferences, 2019
One can prove, there is generally eight various ω − ø mixings forms in elementary particle physics, which on one side give different forms of the vector-meson-nucleon coupling constants through fF, fD and fS in SU(3) invariant Lagrangian of the vector ...

Dyckia semperflorenssp. nov. (Bromeliaceae: Pitcairnioideae) from the cold region of Rio Grande do Sul, southern Brazil

Nordic Journal of Botany, EarlyView.
Dyckia semperflorens (Bromeliaceae: Pitcairnioideae) is described as a new species from the temperate climate region of Rio Grande do Sul state, southern Brazil. The new species belongs to the Dyckia encholirioides complex and is closely related morphologically to Dyckia monticola, which is endemic to the Quiriri mountain range, a high‐altitude region ...
