Approximation of Dirac operators with δ‐shell potentials in the norm resolvent sense, II: Quantitative results

open access: yesMathematische Nachrichten, EarlyView.
Abstract This paper is devoted to the approximation of two‐ and three‐dimensional Dirac operators HV∼δΣ$H_{\widetilde{V} \delta _\Sigma }$ with combinations of electrostatic and Lorentz scalar δ$\delta$‐shell interactions in the norm resolvent sense. Relying on results from Behrndt, Holzmann, and Stelzer‐Landauer [Math. Nachr.

Don't You Know That You're Toxic? How Influencer‐Driven Misinformation Fuels Online Toxicity

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT Research on misinformation has focused on message content and cognitive bias, overlooking how source type shapes toxic engagement. This study addresses that gap by showing that influencer‐driven misinformation does not merely increase toxicity: it reconfigures its nature and persistence through relational and social influence mechanisms ...

Duality for Evolutionary Equations With Applications to Null Controllability

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We study evolutionary equations in exponentially weighted L2$$ {\mathrm{L}}^2 $$‐spaces as introduced by Picard in 2009. First, for a given evolutionary equation, we explicitly describe the ν$$ \nu $$‐adjoint system, which turns out to describe a system backwards in time. We prove well‐posedness for the ν$$ \nu $$‐adjoint system. We then apply

Dynamic RBC‐To‐Membrane Ratio in 129Xe MRI: A Biomarker of Decreased Lung Function in Pulmonary and Vascular Diseases

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To present a method for quantifying dissolved 129Xe spectroscopy using singular value decomposition (SVD) and a dynamic red blood cell (RBC)/membrane ratio as a biomarker of disease. Methods A spectroscopic sequence was performed in 45 subjects (27 healthy, 12 dyspnea of unknown origin [DUO], and 6 pulmonary hypertension [PH ...

Fostering Women's Political Leadership Through Government Accountability: Evidence From OECD Countries

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT Women remain significantly underrepresented in political leadership worldwide. This study examines how different combinations of government accountability mechanisms enhance women's political representation (WPR) as a pathway to leadership in 30 OECD countries.

Single‐Layer Boron Phosphide on Metallic Surfaces: Screening of Promising Substrates

open access: yesphysica status solidi (b), EarlyView.
Hexagonal boron phosphide on Ag (111) and the section of the periodic table with the metals, from IX, X, and XI groups, used as substrates. The structural and electronic properties of single‐layer hexagonal boron phosphide (hBP) on the (111) surface of face‐centered cubic transition metals from the groups IX‐XI are extensively investigated by means of ...
