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

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 ...

Constructive version of Boolean algebra [PDF]

, 2013
The notion of overlap algebra introduced by G. Sambin provides a constructive version of complete Boolean algebra. Here we first show some properties concerning overlap algebras: we prove that the notion of overlap morphism corresponds classically to ...

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.

Method of restoring multivariable Boolean function from its derivative

Advanced Engineering Research, 2017
Introduction. Boolean functions of several variables are of paramount importance in the coding theory and cryptography. The compositions of these functions are used in a set of the symmetric cryptosystems; therewith, some error-control codes, such as ...

On the Nonexistence of Free Complete Boolean Algebras [PDF]

, 1962
Rieger asked in 1951 if there exists a free complete Boolean algebra on ω complete generators. Crawley and Dean proved in 1955 that there does not exist a free complete lattice on three complete generators, but their method does not extend to Boolean ...

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 (
