Attribute Implication Bases From Galois Connection Structures

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Modeling knowledge systems by determining relationships among key variables have been and currently is a fundamental and nontrivial challenge in real‐world scenarios. Many approaches have been developed to reach this goal, but many of them are heuristic and require of alternative procedures to provide robust and tractable rules.

Hydride Reductions of Transition Metal Oxides [PDF]

Chemistry Letters, 2013
Abstract Low-temperature reactions are a powerful approach to generate new transition metal oxides that are inaccessible by conventional high-temperature reactions. In this review, we describe the recent progress of the topochemical reduction method using metal hydrides for transition metal oxides, in particular, focusing on structural ...

From Stability to Chaos: A Complete Classification of the Damped Klein‐Gordon Dynamics

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We investigate the transition between stability and chaos in the damped Klein‐Gordon equation, a fundamental model for wave propagation and energy dissipation. Using semigroup methods and spectral criteria, we derive explicit thresholds that determine when the system exhibits asymptotic stability and when it displays strong chaotic dynamics ...

Multi-Agent RAG Framework for Entity Resolution: Advancing Beyond Single-LLM Approaches with Specialized Agent Coordination

Computers
Entity resolution in real-world datasets remains a persistent challenge, particularly for identifying households and detecting co-residence patterns within noisy and incomplete data.

Transitive Reduction in Parallel via Branchings [PDF]

, 1988
The authors study the following problem: given a strongly connected digraph, find a minimal strongly connected spanning subgraph of it. Their main result is a parallel algorithm for this problem, which runs in polylog parallel time and uses O(n{sup 3}) processors on a PRAM.

Comparative Efficacy of Metabolic/Bariatric Surgery Versus GLP‐1 Receptor Agonists: A Network Meta‐Analysis of Randomized Controlled Trials

Obesity, EarlyView.
ABSTRACT Objective This study compared the efficacy of metabolic/bariatric surgery (MBS) and GLP‐1 receptor agonists (GLP‐1 RAs), including dual GLP‐1/GIP analogues, for weight and metabolic outcomes in adults with obesity. Methods A network meta‐analysis of randomized controlled trials compared MBS or GLP‐1 RAs versus lifestyle intervention in adults ...

An objective Bayesian method for including parameter uncertainty in ensemble model output statistics

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Conventional model output statistics and ensemble model output statistics methods for calibrating ensemble forecasts lead to severe underestimation of the probabilities of ensemble extremes (in blue). This is because they ignore statistical parameter uncertainty.

Robust Control Design and Analysis Based on Lifting Linearization of Nonlinear Systems Under Uncertain Initial Conditions

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper presents a robust control synthesis and analysis framework for nonlinear systems with uncertain initial conditions. First, a deep learning‐based lifting approach is proposed to approximate nonlinear dynamical systems with linear parameter‐varying (LPV) state‐space models in higher‐dimensional spaces while simultaneously ...

Transitive reduction of a rectangular boolean matrix

Discrete Applied Mathematics, 1984
This paper deals with simplification of rectangular Boolean matrices of zeros and ones. For x,y whose values are zero or one, the following operations are defined \(x+y=\max (x,y), x\Theta y=\max (0,x-y)\) and for \(m\times n\) Boolean matrices A,B, \(A\Theta\) B and \(A\leq B\) are defined elementwise.
