A tabu search heuristic based on k-diamonds for the weighted feedback vertex set problem
Given an undirected and vertex weighted graph G = (V,E,w), the Weighted Feedback Vertex Problem (WFVP) consists of finding a subset F ⊆ V of vertices of minimum weight such that each cycle in G contains at least one vertex in F.

Vertex Set Partitions Preserving Conservativeness
, 1997 Let G be an undirected graph and P = fX 1 ; : : : ; X n g be a partition of V (G). Denote by G/P the graph which has vertex set fX 1 ; : : : ; X n g, edge set E, and is obtained from G by identifying vertices in each class X i of the partition P. Given a

Advanced Science, EarlyView.Single‐cell mechanomics demonstrates that pharmacological perturbation changes cytoskeletal and cortical structure, suppressing cancer cell invasiveness. By integrating atomic force microscopy (AFM)‐based cortical measurements with stimulated emission depletion (STED)‐resolved adhesion and cytoskeletal organization, this approach identifies nanoscale ...

On Multidimensional Inequality in Partitions of Multisets [PDF]
We study multidimensional inequality in partitions of finite multisets with thresholds. In such a setting, a Lorenz-like preorder, a family of functions preserving such a preorder, and a counterpart of the Pigou-Dalton transfers are defined, and a ...

Advanced Science, EarlyView.NSD2 coordinates the neurogenic‐to‐gliogenic transition in the developing neocortex through H3K36me2‐dependent activation of EGFR–ERK signaling. Loss of NSD2 disrupts astroglial and oligodendroglial development, whereas ERK activation rescues gliogenic defects in vitro and in vivo.

NbOx Mott Memristor‐Based Oscillatory P‐trit for Ternary Potts Machine
Advanced Science, EarlyView.A ternary Potts machine utilizing NbOx‐based probabilistic trits (p‐trits) is demonstrated for efficient combinatorial optimization. By leveraging the electro‐thermal switching dynamics of NbOx memristors, this architecture generates three‐state stochastic fluctuations.
