We describe a big brake singularity in terms of a modified Chaplygin gas equation of state $p=(ga_{m}-1)ho+alga_{m}ho^{-n}$, accommodate this late-time event as an exotic quintessence model obtained from an energy-momentum ...

In the last years many states in the charmonium mass region were discovery by BABAR, Belle and CDF collaborations I discuss some of these discoveries, and how the QCD Sum Rule approach can be used to understand the structure ...

Using the QCD sum rules we test if the new narrow structure, the X(4350) recently observed by the Belle Collaboration, can be described as a J(PC) = 1(-+) exotic D(s)(*)D(s0)(*) molecular state. We consider the contributions ...

Old fields often become dominated by exotic plants establishing persistent community states. Ecosystem function in such novel plant assemblages may differ widely from that in the alternative, native-dominated counterparts. ...

n1,3S (n = 1 - 4) states for atomic three-body systems are studied with the Angular Correlated Configuration Interaction method. A recently proposed angularly correlated basis set is used to construct, simultaneously and ...

The last few years have been witness to a proliferation of new results concerning heavy exotic hadrons. Experimentally, many new signals have been discovered that could be pointing towards the existence of tetraquarks, ...

Using the QCD sum rule approach we study the Y(4140) state assuming that it can be described by a D* sD* s molecular state with JPC = 0++ quantum numbers. We evaluate the decay width into the channel Y J/ψΦ and we find the ...

Based on recent surveys of the freshwater decapod fauna, distributional data of five exotic species of freshwater decapod crustaceans for the hydrographic basins of the state of São Paulo are presented, as part of a large ...
