Nondiffractive sonic crystals [PDF]
, 2006 We predict theoretically the nondiffractive propagation of sonic waves in periodic acoustic media (sonic crystals), by expansion into a set of plane waves (Bloch mode expansion), and by finite difference time domain calculations of finite beams.

Spectral Analysis of Certain Schr\"odinger Operators [PDF]
, 2012 The $J$-matrix method is extended to difference and $q$-difference operators and is applied to several explicit differential, difference, $q$-difference and second order Askey-Wilson type operators. The spectrum and the spectral measures are discussed in

Asymptotic Expansions for Higher-Order Scalar Difference Equations [PDF]
Advances in Difference Equations, 2007 An asymptotic expansion of the solutions of higher-order Poincaré difference equation in terms of the characteristic solutions of the limiting equation is given. As a consequence, an asymptotic description of the solutions approaching a hyperbolic equilibrium of a higher-order nonlinear difference equation with sufficiently smooth nonlinearity is ...

Reversible data hiding method by extending reduced difference expansion
IJAIN (International Journal of Advances in Intelligent Informatics), 2019 To keep hiding secret data in multimedia files, such as video, audio, and image considers essential for information security. Image, for instance, as the media aids data insertion securely. The use of insertion technique must ensure a reliable process on

Medicaid Expansion Affects Rural And Urban Hospitals Differently [PDF]
Health Affairs, 2016 Rural hospitals differ from urban hospitals in many ways. For example, rural hospitals are more reliant on public payers and have lower operating margins. In addition, enrollment in the health insurance Marketplaces of the Affordable Care Act (ACA) has varied across rural and urban areas.

Simulation study on the deflection and expansion of hydraulic fractures in coal-rock complexes
Energy Reports, 2022 The physical difference and structural weak surface of coal-rock complexes greatly influence the morphology of hydraulic fractures (HFs). This study aims to explore the law of deflection and expansion of HFs in coal-rock complexes under different stress ...
