Shack–Hartmann Wavefront Sensing Based on Four-Quadrant Binary Phase Modulation

open access: yesPhotonics, 2022
Aiming at the problem that it is difficult for the conventional Shack–Hartmann wavefront sensor to achieve high-precision wavefront reconstruction with low spatial sampling, a kind of Shack–Hartmann wavefront sensing technology based on four-quadrant ...

Polynomial Solution of Non-Central Potentials [PDF]

open access: yes, 2007
We show that the exact energy eigenvalues and eigenfunctions of the Schrodinger equation for charged particles moving in certain class of non-central potentials can be easily calculated analytically in a simple and elegant manner by using Nikiforov and ...

Consumer Valuation of Meat Alternatives and Labeling Policies: A Comparative Perspective

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study investigates and compares US consumer perceptions and the impact of environmental, human health, and animal welfare information related to conventional meat on preferences for meat alternatives and labeling policies. Using the best–worst scaling method across 10 different burger alternatives, our results show that the meat burger is

Decoding of Quasi-Cyclic Codes up to A New Lower Bound on the Minimum Distance

open access: yes, 2014
A new lower bound on the minimum Hamming distance of linear quasi-cyclic codes over finite fields is proposed. It is based on spectral analysis and generalizes the Semenov- Trifonov bound in a similar way as the Hartmann-Tzeng bound extends the BCH ...

Large-wavelength instabilities in free-surface Hartmann flow at low magnetic Prandtl numbers

open access: yes, 2008
We study the linear stability of the flow of a viscous electrically conducting capillary fluid on a planar fixed plate in the presence of gravity and a uniform magnetic field. We first confirm that the Squire transformation for MHD is compatible with the
