Asymptotic properties of the spectrum of neutral delay differential equations

, 2009
Spectral properties and transition to instability in neutral delay differential equations are investigated in the limit of large delay. An approximation of the upper boundary of stability is found and compared to an analytically derived exact stability ...

Photoactivation of NV Centers in Diamond via Continuous Wave Laser Illumination of Shallow As‐Implanted Nitrogen

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 ...

A study on the oscillation of second-order neutral differential equations in noncanonical form

Electronic Journal of Qualitative Theory of Differential Equations
This paper analyzes the oscillation of the second-order neutral differential equation in noncanonical form \[ \left[r(t)\left(\left(x(t)+p(t)x(\pi(t))\right)^{\prime}\right)^{\alpha}\right]^{\prime} + k(t)x^{\beta}(\eta(t))=0.

Measurements of Coronal Faraday Rotation at 4.6 Solar Radii

, 2014
Many competing models for the coronal heating and acceleration mechanisms of the high-speed solar wind depend on the solar magnetic field and plasma structure in the corona within heliocentric distances of $5R_\odot$.

Dissipative Field Theory with Caldeira-Leggett Method and its Application to Disoriented Chiral Condensation [PDF]

, 1997
The effective field theory including the dissipative effect is developed based on the Caldeira-Leggett theory at the classical level. After the integration of the small field fluctuations considered as the field radiation, the integro-differential field ...

Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

Advanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...
