Flat band degeneracy and near-zero refractive index materials in acoustic crystals
AIP Advances, 2016 A Dirac-like cone is formed by utilizing the flat bands associated with localized modes in an acoustic crystal (AC) composed of a square array of core-shell-structure cylinders in a water host.

Track-Before-Detect Procedures in AM Radio-Based Passive Radar
International Journal of Antennas and Propagation, 2021 In amplitude modulation radio-based passive radar, the track-before-detect (TBD) procedures are performed to process long time observation data. This work mainly focuses on the tracking of the time-Doppler and time-azimuth traces of multiple target under

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Recirculation in multiple wave conversions [PDF]
, 2008 A one-dimensional multiple wave-conversion model is constructed that allows energy recirculation in ray phase space. Using a modular eikonal approach, the connection coefficients for this model are calculated by ray phase-space methods.

DEM modeling of wave propagation through jointed rock mass
, 2013 Numerical study on wave transmission across jointed rock masses is performed with a DEM-based code UDEC. As the first step, the numerical results of wave transmission across rock joints are compared with analytical solutions and in-situ data.
