Phase transitions and dimensional reduction
Nuclear Physics B, 1991 Using field theoretic methods a formalism is presented within which the critical behaviour of a system undergoing a dimensional reduction may be investigated. As a paradigm we study an Ising-like system on S1 × R3−ϵ. If the size of the system is L, and the correlation length ξ, then as Lξ varies it is possible to get critical behaviour associated with ...

Advanced Intelligent Discovery, EarlyView.scTIGER2.0 is a deep‐learning framework that infers gene regulatory networks from single‐cell RNA sequencing data. By integrating correlation, pseudotime ordering, deep learning and bootstrap‐based significance testing, it reduces false positives and reveals directional gene interactions.

Materials Representation Learning Based on a Material–Motif Network and Heterogeneous Graphs
Advanced Intelligent Discovery, EarlyView.Structure motifs in materials are used to construct a bipartite material–motif network that links each material to its constituent motifs and establishes connectivity among materials sharing common motifs. Network analysis reveals material clusters associated with different functional applications and supports motif‐guided screening of materials.

Transitive reduction of a nilpotent boolean matrix
Discrete Applied Mathematics, 1984 Given an acyclic digraph, a problem which frequently arises in applications consists in removing the maximum number of arcs without affecting reachability. This removal corresponds to a so-called transitive reduction of the adjacency matrix of the given digraph.

Business Strategy and the Environment, EarlyView.ABSTRACT Reaching global net‐zero targets has become an urgent priority as businesses and nations face increasing pressure to reduce greenhouse gas emissions. Achieving carbon neutrality in manufacturing supply chains requires comprehensive systemic changes across business processes.

Supply Chain Network, ESG Scores and Financial Performance
Business Strategy and the Environment, EarlyView.ABSTRACT This paper provides novel evidence on the role of supply chain networks in influencing firms' environmental, social and governance (ESG) scores and financial performance. Our analysis employs financial, board, ESG and supply chain data, resulting in an unbalanced panel of over 16,000 firm‐year observations from 3028 publicly traded US firms ...

, 2007 Quick note to self, having stumbled on the Wikipedia page on transitive reduction. Given a graph like this: the transitive reduction is: Note that the original graph has an edge a -> d, but this is absent after the reduction because we can get from a to d via b (or c). What's the point?

Business Strategy and the Environment, EarlyView.ABSTRACT Rice production sustains food security and rural livelihoods across many low‐income countries but remains highly vulnerable to climate‐related hazards, including floods, droughts, salinity intrusion and heat stress, which reduce yields and threaten the long‐term sustainability of rice production.

Parameterized Linear Time Transitive Closure
Journal of Graph Algorithms and ApplicationsIn this paper, we first study the problem of decomposing a directed acyclic graph (DAG), $G=(V, E)$ into vertex-disjoint chains and present a fast and practical chain decomposition technique.
