Prediction-error expansion (PEE) is an important reversible data hiding technique, which can hide large messages into digital media with little distortion. In this paper , we propose a nearest neighborhood pixel prediction algorithm (NNP 2) for reversible data hiding algorithms based on Chinese Remainder Theorem (CRT), in which a rhombus prediction is(More)
Sacbrood virus (SBV) primarily infects honeybee broods, and in order to deal with the problem cost effective detection methods are required. A one-step reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay was developed for the rapid identification of SBV. The data demonstrated that, in a simple water bath, SBV RNA could be detected(More)
BACKGROUND Goose parvovirus (GPV) is a Dependovirus associated with latent infection and mortality in geese. Currently, in a worldwide scale, GPV severely affects geese production. The objective of this study is to develop a loop-mediated isothermal amplification (LAMP) method for the sensitive, rapid, and inexpensive detection of GPV in the field. (More)
Occupant evacuation dynamics is a kind of many-body system of strongly interacting persons. A great deal of factors should be taken into account in the study of fire evacuation, such as human behavior, fire products and architecture. To describe human behavior, there are two different evacuation models, the social force model and the lattice-gas model.(More)
