We establish, as an application of the results from [13], an h-principle for exact Lagrangian immersions with transverse self-intersections and the minimal, or near-minimal number of double points. One corollary of our result is that any orientable closed 3-manifold admits an exact Lagrangian immersion into standard symplectic 6space R6st with exactly one transverse double point. Our constructi...

Unusual scattering effects from tiny spherical particles may be obtained when concentric shells are designed by pairing together "complementary" double-negative, single-negative, and/or standard double-positive materials. By embedding these highly polarizable scatterers in a host medium one can achieve a bulk medium with interesting effective parameters. Some physical insights and justification...

Record linkage is the problem of identifying similar records across different data sources. The similarity between two records is defined based on domain-specific similarity functions over several attributes. In this paper, a novel approach is proposed that uses a two level matching based on double embedding. First, records are embedded into a metric space of dimension K, then they are embedded...

In image steganography, a pixel can carry secret bits by choosing adding/subtracting one to/from the gray value. This kind of “ 1 steganography” can hide a longer message than simple LSB embedding. We propose a double-layered embedding method for implementing “ 1 steganography,” in which binary covering codes and wet paper codes are used to hide messages in the LSB plane and the second LSB plan...

In our previous work, we introduced a double-sided technique that utilizes but not reject the host interference. Due to its nice property of utilizing but not rejecting the host interference, it has a big advantage over the host interference schemes in that the perceptual analysis can be easily implemented for our scheme to achieve the locally bounded maximum embedding strength. Thus, in this w...

Among the adaptive-grid methods, redistribution and embedding techniques have been the focus of more attention by researchers. Simultaneous or combined adaptive techniques have also been used. This paper describes a combination of adaptive-grid embedding and redistribution methods on semi-structured grids for two-dimensional invisid flows. Since the grid is semi-structured, it is possible to us...
