Unfoldings and coverings of weighted graphs
, 2020 We study unfoldings of directed graphs and coverings of undirected ones, so as to highlight the similarities between the two notions. We generalize them by attaching finite or infinite weights to edges.

Advanced Functional Materials, EarlyView.An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Abstract Clustering by weighted cuts in directed graphs
, 2008 In this paper we formulate spectral clustering in directed graphs as an optimization problem, the objective being a weighted cut in the directed graph.

Exploiting structure to cope with NP-hard graph problems: Polynomial and exponential time exact algorithms [PDF]
, 2010 An ideal algorithm for solving a particular problem always finds an optimal solution, finds such a solution for every possible instance, and finds it in polynomial time.

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Vanishing of Hochschild Cohomologies and Directed Graphs with Polynomial Weights
Journal of Algebra, 1993 In what follows, \(\Lambda\) denotes a finite dimensional algebra over an algebraically closed field \(K\). This paper addresses a question raised by \textit{H. Tachikawa} [``Quasi-Frobenius Rings and Generalizations'' (Lect. Notes Math. 351, 1973; Zbl 0271.16004)], namely: Is \(\Lambda\) self- injective if the Hochschild cohomologies \(H^ i(\Lambda ...

Advanced Functional Materials, EarlyView.Multianalyte, real‐time monitoring of bioprinted scaffolds remains challenging. Phosphorescence‐lifetime–based, optically responsive microparticles are embedded in diverse printable hydrogels (κ‐carrageenan, GelMA, PEGDA) to form biomaterial inks that report oxygen, glucose, lactate, and temperature.

Quantifying and comparing causal patterns in stochastic chemical reaction networks
npj Systems Biology and ApplicationsChemical reaction networks (CRNs) are broadly used to study biological systems via simulations. Gillespie’s Stochastic Simulation Algorithm (SSA) is commonly used to perform stochastic simulations with CRNs. Comparing two CRNs in such a setting relies on

Advanced Functional Materials, EarlyView.A compostable PGS soft surgical robot with interchangeable modules integrates transient Mo tactile and Si thermal sensors for dual feedback. The device preserves its function after clinical‐grade sterilization, demonstrates stable actuation and cardiac tissue grasping with real‐time in vivo pulsatile monitoring, and biodegrades post‐use with soil‐safe,
