A spatial time series dataset is a collection of time series, each referencing a location in a common spatial framework. Correlation analysis is often used to identify pairs of potentially interacting elements from the cross product of two spatial time series datasets. However, the computational cost of correlation analysis is very high when the dimension of the time series and the number of lo...

II. REGION SELECTION BASED ON ENTROPY VALUES Abstract—The present paper describes a compression resilient data hiding scheme in spatial domain by inserting data in different blocks in the cover image. The blocks are selected based on the value of information content that is measured using an exponential form of entropy. Experimental results show the resiliency of the scheme against several unin...

Ultrafast photoexcitation can induce a nonequilibrium dynamic with electron-lattice interaction, offering an effective way to study photoinduced phase transitions (PIPTs) in solids. The issue that atomic displacements after belong coherent change or disordered process, has become controversy the PIPT community. Using real-time time-dependent density functional theory (rt-TDDFT) simulations, we ...
