TL;DR: This paper developed a many-body lattice model for a three-component system of proteins with fixed valence in a solvent, and compared the predictions of the model to experimental phase diagrams that they measure in vivo, which allows them to vary specifically a binding site's affinity and valency.
Abstract: Biomolecular self-assembly spatially segregates proteins with a limited number of binding sites (valence) into condensates that coexist with a dilute phase. We develop a many-body lattice model for a three-component system of proteins with fixed valence in a solvent. We compare the predictions of the model to experimental phase diagrams that we measure in vivo, which allows us to vary specifically a binding site's affinity and valency. We find that the extent of phase separation varies exponentially with affinity and increases with valency. Valency alone determines the symmetry of the phase diagram.

Abstract: To provide a phosphor given by a general composition formula expressed by MmAaBbOoNn:Z, (wherein element M is one or more kinds of elements having bivalent valency, element A is one or more kinds of elements having tervalent valency, element B is one or more kinds of elements having tetravalent valency, O is oxygen, N is nitrogen, and element Z is one or more kinds of activating agent, satisfying m > 0, a > 0, b > 0, o ≥ 0, and n > 0), with a change rate of a ratio of element B atoms to the total numbers of atoms being smaller by 10% or the change rate of oxygen atoms to the total numbers of atoms being smaller by 40% in a range from a particle surface up to depth 2000nm, having a broad emission spectrum in a range of blue color, having a broad flat excitation band in a range of near ultraviolet/ultraviolet, and having excellent emission efficiency, emission intensity, and luminance.
