A triviality result in the AdS/CFT correspondence for Euclidean quantum fields with exponential interaction

, 2013
We consider scalar quantum fields with exponential interaction on Euclidean hyperbolic space $\mathbb{H}^2$ in two dimensions. Using decoupling inequalities for Neumann boundary conditions on a tessellation of $\mathbb{H}^2$, we are able to show that the

Engineered Mycelial Scaffolds With Tunable Ultraviolet Protection, Wettability, Thermal Stability, and Spatial Mechanics

Advanced Engineering Materials, EarlyView.
Fungal mycelia grown into biodegradable scaffolds and infused with titania nanoparticles show enhanced ultraviolet shielding, thermal protection, and surface nonwettability. Properties were tuned by drying methods, revealing structure–function relationships.

Experimental study on the p-wave velocity characteristics of the cement-stabilized soil [PDF]

AIP Advances
Cement-stabilized soils, as a typical representative of soil improvement methods, significantly enhance the performance of soft soil. Since the demand for non-destructive assessment of the compressive and shear strength of cement-stabilized soil (CSS) is

On exponential functionals, harmonic potential measures and undershoots of subordinators

, 2014
We establish a link between the distribution of an exponential functional I and the undershoots of a subordinator, which is given in terms of the associated harmonic potential measure.

On the distribution of the Wigner time delay in one-dimensional disordered systems

, 1997
We consider the scattering by a one-dimensional random potential and derive the probability distribution of the corresponding Wigner time delay. It is shown that the limiting distribution is the same for two different models and coincides with the one ...

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Well-posedness and exponential stability of swelling porous with Gurtin–Pipkin thermoelasticity and delay term

Partial Differential Equations in Applied Mathematics
This work examines the exponential stability and well-posedness of a swelling porous system with the Gurtin–Pipkin thermal effect as the sole source of damping over time. We use an essential corollary to the Lumer–Phillips Theorem to demonstrate the well-

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.
