Advanced Functional Materials, EarlyView.This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

$L^p$ - $L^q$ estimates for damped wave equations with odd initial data
Electronic Journal of Differential Equations, 2005 We study the Cauchy problem for the damped wave equation. In a previous paper [16] the author has shown the $L^p$ - $L^q$ estimates between the solutions of the damped wave equation and the solutions of the corresponding heat equation.

Distributed Control of a Vibrating String in Response to Pointwise Force Application
Sakarya Üniversitesi Fen Bilimleri Enstitüsü DergisiThe problem of controlling the vibrations of a string by a discrete applied force is considered. The vibrations of the string are modeled by the linear wave equation and the control is provided by an added force term.

Approximate asymptotic integration of a higher order water-wave equation using the inverse scattering transform [PDF]
Nonlinear Processes in Geophysics, 1997 The complete mathematical and physical characterization of nonlinear water wave dynamics has been an important goal since the fundamental partial differential equations were discovered by Euler over 200 years ago.

Experimental and Theoretical Confirmation of Covalent Bonding in α‐Pu
Advanced Functional Materials, EarlyView.From a combination of Reverse Monte Carlo dynamic rigid body fitting to the pair distribution functional and novel density functional approaches, the existence of covalent bonding is confirmed in α‐plutonium alongside other bonding types (i.e. mixed bonding schemes).
