in this paper, using annular resonator we have designed an adding and dropping filter light based ontwo-dimensional photonic crystals. the shape of ring resonator filter adding and dropping that wehave proposed is race track. this filter has a hexagonal lattice structure of silicon bars withrefractive index 3/46 that is located in the context of air with refractive index 1. transmissionefficien...

Pions of a dark sector gauge group can be strongly interacting massive particle (SIMP) matter, produced by the freeze-out $3 \to 2$ interactions, with naturally large self-interactions. We study if adding photon to set-up do it all: i) maintain thermalization visible sector, ii) resonantly enhance $3\to2$ thus allowing for perturbative pion description, and iii) provide velocity dependent self-...

Recent scientific analysis has revealed the presence in AFA of the amino acid phenyl ethylamine (PEA) in significant concentration. PEA is well known to alleviate depression, to elevate mood and to play an important role in the pathogenesis of learning disability and attention deficit disorder. Aphanin" is a standardized cold-processed extract of AFA that contains high concentrations of PEA, an...
