The Hautus-Type Inequality for Abstract Fractional Cauchy Problems and Its Observability

Journal of Mathematics
In this paper, we investigate the observability of the fractional resolvent family, and we prove two main results: the first result shows a generalization of the Hautus-type test for observable exponentially stable semigroups to the fractional resolvent ...

Decoding Emotional Signatures of Ethical Ads: An Analysis of Actor‐Viewer Synchrony

Journal of Consumer Behaviour, EarlyView.
ABSTRACT We examine whether ethical advertisements differ from conventional ads in their on‐screen emotional signatures and whether those signatures transfer to actor‐viewer synchrony. Study 1 analyses 138 professionally produced YouTube ads using Automated Facial Expression Recognition (AFER) and Convolutional Neural Networks (CNN) to quantify actor ...

How Does Academic Marginalization Impact Mental Well‐Being? Exploring the Mediating Roles of Vocational Identity and Occupational Engagement

The Career Development Quarterly, EarlyView.
ABSTRACT In an increasingly volatile global job market, students’ career development is shaped by both personal capacities and structural barriers. This study examined how academic marginalization—particularly related to educational background—influences the mental well‐being of South Korean college students, with attention to the mediating roles of ...

Optimal model‐based design of experiments for parameter precision: Supercritical extraction case

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from flowers. A parameter‐distributed model consisting of a set of partial differential equations is used to describe the governing mass transfer phenomena in a cylindrical packed bed with solid chamomile particles under supercritical conditions using carbon dioxide as a solvent ...

Carleman estimates and null controllability of degenerate/singular parabolic systems

Electronic Journal of Differential Equations, 2016
We study null controllability properties for parabolic coupled systems with degeneracy and singularity occurring in the interior of the spatial domain.

Restricted Tweedie stochastic block models

Canadian Journal of Statistics, EarlyView.
Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.

Uniform indirect boundary observability for a spatial discretization of strongly coupled wave equations

Partial Differential Equations in Applied Mathematics
This paper investigates the indirect boundary observability properties of one-dimensional strongly coupled wave equations in an approximated setting. Classical numerical discretization methods, such as finite differences and finite elements, typically ...

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Tokenism or Catalytic? Exploring Board Gender Diversity Through the Lens of SDG 9 Outcomes in the EU Context

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study explores the relationship between Executive gender diversity (EGD) and the achievement of Sustainable Development Goal 9 (SDG 9—Industry, Innovation, and Infrastructure) in the European Union. It investigates whether female representation in corporate governance contributes to innovation‐driven sustainability.

Null controllability of a coupled system of degenerate parabolic equations with lower order terms

Electronic Journal of Differential Equations, 2019
This article concerns the null controllability of a control system governed by coupled degenerate parabolic equations with lower order terms. For these equations, the convection terms cannot be controlled by the diffusion terms.
