Bell-Boole Inequality: Nonlocality or Probabilistic Incompatibility of Random Variables?

Entropy, 2008
The main aim of this report is to inform the quantum information community about investigations on the problem of probabilistic compatibility of a family of random variables: a possibility to realize such a family on the basis of a single probability ...

Impact of Packaging and Recycling Systems on Material Recirculation: A Stage‐Decomposition Model

Packaging Technology and Science, EarlyView.
A system‐level view emerges from decomposing recycling into four stages (participation, collection, sorting and process yield), diagnosing constraints and targeting interventions. Cumulative equivalent uses (CEUs) quantify long‐term retention, revealing marginal improvements at high baselines generate disproportionately larger gains than low‐baseline ...

Two hearts that beat as one: Signals, narratives, and financing (less) novel ventures via equity crowdfunding

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Financial resource acquisition is crucial for ventures but hindered by uncertainty. While signaling mitigates this uncertainty, its effectiveness hinges on venture novelty and the narratives used to clarify embedded information. Adopting a configurational lens, we examine the interplay among novelty, signals, and narratives in

Merging Intuitionistic and De Morgan Logics

Mathematics
We introduce De Morgan Heyting logic for Heyting algebras with De Morgan negation (DH-algebras). The variety DH of all DH-algebras is congruence distributive. The lattice of all subvarieties of DH is distributive.

On Fuzzy Ideals of BL-Algebras

The Scientific World Journal, 2014
In this paper we investigate further properties of fuzzy ideals of a BL-algebra. The notions of fuzzy prime ideals, fuzzy irreducible ideals, and fuzzy Gödel ideals of a BL-algebra are introduced and their several properties are investigated.

Modelling Hierarchical Configurations in Innovation Research With Two‐Step QCA: Methodological Recommendations and an Application to Workarounds

Creativity and Innovation Management, EarlyView.
ABSTRACT Creativity and innovation are often understood as the result of a complex interplay of hierarchical factors, such as national, regional and firm characteristics, or between organisational and individual factors. While recent applications of qualitative comparative analysis (QCA) have begun to model such configurational links, their ...

Safe Stabilization Using Non‐Smooth Control Lyapunov Barrier Function

International Journal of Robust and Nonlinear Control, Volume 36, Issue 11, Page 5823-5835, 25 July 2026.
ABSTRACT This paper addresses the challenge of safe stabilization, ensuring the system state reaches the origin while avoiding unsafe state regions. Existing approaches that rely on smooth Lyapunov barrier functions often fail to guarantee a feasible controller. To overcome this limitation, we introduce the non‐smooth control Lyapunov barrier function (
