European Physical Journal C: Particles and FieldsWe construct the generalized $$\beta $$ β and (q, t)-deformed partition functions through W representations, where the expansions are respectively with respect to the generalized Jack and Macdonald polynomials labeled by N-tuple of Young diagrams.

Cubic Graphs with Total Domatic Number at Least Two
Discussiones Mathematicae Graph Theory, 2018 Let G be a graph with no isolated vertex. A total dominating set of G is a set S of vertices of G such that every vertex is adjacent to at least one vertex in S.

Boosting Vertex-Cut Partitioning for Streaming Graphs
2016 IEEE International Congress on Big Data (BigData Congress), 2016 While the algorithms for streaming graph partitioning are proved promising, they fall short of creating timely partitions when applied on large graphs. For example, it takes 415 seconds for a state-of-the-art partitioner to work on a social network graph with 117 millions edges.

Hybrid Amyloid–Boron Nitride Aerogels for Lightweight Sound Insulation
Advanced Materials, EarlyView.Amyloid fibrils template the mild formation of boron nitride–rich hybrid aerogels with hierarchical porosity, enhanced BN‐like ordering, and fibril‐reinforced mechanics. These ultralight materials combine thermal stability with strong sound absorption and transmission loss, offering a sustainable bio‐assisted route toward lightweight acoustic shields ...

O-vertex, O7 + -plane, and topological vertex
Journal of High Energy PhysicsWe revisit the instanton partition function for 5d N $$ \mathcal{N} $$ = 1 SO(N) gauge theories compactified on S1, computed from the topological vertex formalism with the O-vertex based on a 5-brane web diagram with an O5-plane. We introduce an identity

Photo‐ and Thermally‐Induced Huge Layer Decoupling in Twisted Bilayer WSe2
Advanced Materials, EarlyView.A newly developed automated dark‐field tomography visualizes twist‐angle‐dependent structural relaxation and quantifies 3D structures in twisted bilayer WSe2. This approach reveals the evolution of local stacking configurations, thermally induced sub‐ångström interlayer decoupling, and light‐driven interlayer expansion on picosecond timescales ...

, 2011 We prove a general lemma about partitioning the vertex set of a graph into subgraphs of bounded degree. This lemma extends a sequence of results of Lovász, Catlin, Kostochka and Rabern.

Advanced Materials, EarlyView.Hydration‐induced symmetry breaking transforms layered LiInP2S6${\rm LiInP}_2{\rm S}_6$ from a nonpolar to a chiral‐polar phase, producing a giant enhancement of non‐resonant second‐harmonic generation. The reversible tuning of polar order through molecular intercalation establishes a strategy for dynamically controlling nonlinear optical ...

On Subgraphs Induced by Transversals in Vertex-Partitions of Graphs [PDF]
The Electronic Journal of Combinatorics, 2006 For a fixed graph $H$ on $k$ vertices, we investigate the graphs, $G$, such that for any partition of the vertices of $G$ into $k$ color classes, there is a transversal of that partition inducing $H$. For every integer $k\geq 1$, we find a family ${\cal F}$ of at most six graphs on $k$ vertices such that the following holds.
