On the Distribution of the Information Density of Gaussian Random Vectors: Explicit Formulas and Tight Approximations [PDF]

Entropy, 2022
Based on the canonical correlation analysis, we derive series representations of the probability density function (PDF) and the cumulative distribution function (CDF) of the information density of arbitrary Gaussian random vectors as well as a general ...

Reactive Nanoparticle Composed Bilayers: An Alternate Route Toward the Production of Pt/Al Nanofoils. [PDF]

Small
Spark ablation‐assisted gas phase electrodeposition is an alternate route toward Pt/Al self‐propagation reactive system synthesis. Pt film morphology‐dependent reaction kinetics is a significant advantage. Low spark power and gas flow rate produce porous films and slow speeds, while high power and flow rate give three orders of magnitude faster ...

Impact of Thermal Treatment on Growth Factor Levels in Injectable Horizontal Platelet-Rich Fibrin: An In Vitro Study. [PDF]

Clin Exp Dent Res
ABSTRACT Background Platelet‐rich fibrin (PRF) is widely recognized for its regenerative properties in periodontal therapy, particularly through the release of endogenous growth factors. Injectable horizontal PRF (H‐PRF), a recent advancement, has gained interest due to its improved cell distribution and structural integrity.

DFT-Assisted Approach to Low-Temperature Graphene Growth on Sapphire. [PDF]

Small
The crystallographic orientation of sapphire strongly affects low‐temperature plasma‐enhanced chemical vapor deposition graphene growth. Experiments combined with density functional theory reveal that surface oxygen coordination governs carbon adsorption and nucleation: lower‐coordinated sites on a‐plane sapphire promote rapid growth, while higher ...

Using quasi-guided modes for modeling the transfer behavior of bent dielectric slab waveguides [PDF]

Advances in Radio Science, 2010
The connection of two straight dielectric multimode slab waveguides by a circular bent waveguide is analyzed by means of quasi-guided modes. These modes correspond to the well known leaky modes, but own real eigenvalues, thus the mathematical ...
