Emergent coherent structures in nonequilibrium field theory.
Coherent states. Quantum field theory. Nonlinear theories.
In this thesis we study the properties of time-dependent, nontopological configurations and their effect on the macroscopic properties of a system described by a nonlinear field theory. These structures seem to be ubiquitous in relativistic field...

Interleukin-2 analogs with enhanced biological response: a novel ligand based mechanism.
Interleukin-2 -- Derivatives. ; Interleukin-2 -- Receptors. ; Ligand binding (Biochemistry).
Interleukin-2 (IL-2) is an immunoregulatory cytokine whose biological effects are mediated through interaction with specific receptors (IL-2R) on the surface of target cells. Due to its presumed role in generating a normal immune response, IL-2 is...
