ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study presents a novel quantum dot electrophoretic display (QDEPD), which combines electro‐controlled reflection and optically‐triggered emission to achieve efficient multi‐modal switching within a single pixel. By incorporating multi‐component nanostructures, the system enhances functional integration and multi‐modal response capabilities.

Descents, Quasi-Symmetric Functions, Robinson-Schensted for Posets, and the Chromatic Symmetric Function [PDF]
Journal of Algebraic Combinatorics, 1999 The author presents a new version of the expansion of Stanley's chromatic symmetric function [\textit{R. P. Stanley}, Discrete Math. 5, 171-178 (1973; Zbl 0258.05113)] in terms of Gessel's fundamental quasi-symmetric functions [\textit{I. M. Gessel}, Combinatorics and algebra, Proc. Conf., Boulder/Colo. 1983, Contemp. Math.

Positivity for Stanley's chromatic functions
, 2016 This dissertation is dedicated to the study of positivity phenomena for the coefficients of the chromatic symmetric function of a graph. This function was introduced by Stanley in 1995 as a generalization of the chromatic polynomial of a graph.

Signed Projective Cubes, a Homomorphism Point of View
Journal of Graph Theory, EarlyView.ABSTRACT The (signed) projective cubes, as a special class of graphs closely related to the hypercubes, are on the crossroad of geometry, algebra, discrete mathematics and linear algebra. Defined as Cayley graphs on binary groups, they represent basic linear dependencies.

Fractional Balanced Chromatic Number and Arboricity of Planar (Signed) Graphs
Journal of Graph Theory, EarlyView.ABSTRACT A balanced ( p , q ) $(p,q)$‐coloring of a signed graph ( G , σ ) $(G,\sigma )$ is an assignment of q $q$ colors to each vertex of G $G$ from a platter of p $p$ colors, such that each color class induces a balanced set (a set that does not induce a negative cycle).

Characters and chromatic symmetric functions
, 2020 Let $P$ be a poset, $inc(P)$ its incomparability graph, and $X_{inc(P)}$ the corresponding chromatic symmetric function, as defined by Stanley in {\em Adv. Math.}, {\bf 111} (1995) pp.~166--194.
