Enabling the Application of Graph Neural Networks on Graphs With Unknown Connectivity
Expert Systems, Volume 42, Issue 8, August 2025.ABSTRACT Graph Neural Networks (GNNs) have proven to be reliable methods for working with graph‐structured data. However, it is common to find graphs with partially or fully inaccessible connectivity patterns, hindering the direct application of GNNs to the task at hand.

Studies on Fractional Differential Equations With Functional Boundary Condition by Inverse Operators
Mathematical Methods in the Applied Sciences, Volume 48, Issue 11, Page 11161-11170, 30 July 2025.ABSTRACT Fractional differential equations (FDEs) generalize classical integer‐order calculus to noninteger orders, enabling the modeling of complex phenomena that classical equations cannot fully capture. Their study has become essential across science, engineering, and mathematics due to their unique ability to describe systems with nonlocal ...

Symmetrization for fractional elliptic and parabolic equations and an isoperimetric application
, 2015 We develop further the theory of symmetrization of fractional Laplacian operators contained in recent works of two of the authors. The theory leads to optimal estimates in the form of concentration comparison inequalities for both elliptic and parabolic ...

Synthesis and Reactivity of Triphosphaallyl Cation Stabilized by N‐Heterocyclic Carbenes
Chemistry – A European Journal, Volume 31, Issue 37, July 2, 2025.Imidazoliumyl‐substituted triphosphaallyl cations undergo selective P–C bond cleavage and form unprecedented bicyclic P₃‐Ga scaffolds with unique reactivity. Abstract Reduction of the triphosphaallyl species 6[GaCl4] with GaI[Ga2Cl7] affords the imidazoliumyl‐substituted (L) bicyclo[2.1.1]‐triphosphane 10[Ga2Cl7], featuring an unprecedented Ga2Cl5 ...

Electric Field Inhomogeneity in Colloidal QD‐LEDs
Advanced Optical Materials, Volume 13, Issue 19, July 4, 2025.Variations in the thickness of the quantum dot (QD) active layer in a quantum dot light emitting diode leads to variations in the local electric field strength. Thicker regions insulate the QDs from the applied electric field. Under normal operating conditions, this leads to lower electroluminescence.

A finite-volume scheme for fractional diffusion on bounded domains
European Journal of Applied MathematicsWe propose a new fractional Laplacian for bounded domains, expressed as a conservation law and thus particularly suited to finite-volume schemes. Our approach permits the direct prescription of no-flux boundary conditions.

Advanced Science, Volume 12, Issue 25, July 3, 2025.Utilizing a stereotaxic injection mouse model and a novel mathematical approach, this study uncovers key subnetworks that drive pathological α‐synuclein (α‐Syn) progression in Parkinson's disease (PD). Remarkably, just 2% of the strongest connections in the connectome are sufficient to predict its spread.
