$\delta$ meson effects on neutron stars in the modified quark-meson coupling model
, 2008 The properties of neutron stars are investigated by including $\delta$ meson field in the Lagrangian density of modified quark-meson coupling model. The $\Sigma^-$ population with $\delta$ meson is larger than that without $\delta$ meson at the beginning,

Color polymorphism in Anemone coronaria: Correlations with soil, climate, and flowering phenology
American Journal of Botany, EarlyView.Abstract Premise Flower color polymorphism (FCP) is thought to be driven by multiple selection agents. Although widely associated with visual attraction of multiple pollinators, FCP is also often correlated with abiotic factors. We explored the links between abiotic conditions, flowering phenology, and FCP in the winter‐flowering geophyte Anemone ...

Free energies as invariants of Teichmüller like structures [PDF]
, 2013 A Teichmüller like structure on the space of d-degree holomorphic maps on the circle S1, marked by conjugations to the map z 7→ z d, can be defined. Here we introduce a definition of free energy associated to this kind of dynamics as an invariant of ...

Effective meson masses, effective meson-nucleon couplings and neutron star radii
, 2004 Using the generalized mean field theory, we have studied the relation among the effective meson masses, the effective meson-nucleon couplings and the equation of state (EOS) in asymmetric nuclear matter.

Medium induced Lorentz symmetry breaking effects in nonlocal PNJL models [PDF]
, 2014 In this paper we detail the thermodynamics of two flavor nonlocal Polyakov-Nambu-Jona-Lasinio models for different parametrizations of the quark interaction regulators.

The non-perturbative unquenched quark model
EPJ Web of Conferences, 2017 In recent years states in the quarkonium spectrum not expected in the naive quark model have appeared and created a lot of interest. In the theoretical side the study of the effect of meson-meson thresholds in the spectrum have been performed in ...

Resolving the RpA and v2 puzzle of D0 mesons in p−Pb collisions at the LHC
Physics Letters B, 2023 It has been a challenge to understand the experimental data on both the nuclear modification factor and elliptic flow of D0 mesons in p−Pb collisions at LHC energies.

American Journal of Botany, EarlyView.Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...
