The quasiparticle interference of the spectroscopic imaging scanning tunneling microscopy has been investigated for the surface states of the large gap topological insulator Bi2Te3 through the T-matrix formalism. Both the scalar-potential scattering and the spin-orbit scattering on the warped hexagonal isoenergy contour are considered. While backscatterings are forbidden by time-reversal symmet...

A CR-slant warped product is considered a generalization of CR-warped product. It was firstly introduced and studied in the field Kaehler geometry. In this paper, we study products nearly trans-Sasakian manifolds. We obtain general inequality related to second fundamental form warping function such products. The equality case discussed.

This paper presents a novel technique for efficient restoration of arbitrarily warped document images. Our aim is to recover document images that are mainly bounded volumes captured by a digital camera and suffer from non-linear warp. The proposed technique is applied on gray scale document images and is based on several distinct steps: an adaptive document image binarization, a text line and w...

We present a class of dynamical solutions for an intersecting D4-D8 brane system in ten-dimensional type IIA supergravity. The dynamical solutions reduces to a static warped AdS6 × S geometry in a certain spacetime region. We also consider lower-dimensional effective theories for the warped compactification of general p-brane system. It is found that an effective p + 1-dimensional description i...

In this paper, we present a linear transformation (LT) to obtain warped features from unwarped features during vocal-tract length normalisation (VTLN). This LT between the warped and unwarped features is obtained within the conventional MFCC framework without any modification in the signal processing steps involved during the feature extraction stage. Further using the proposed LT, we study the...

We review results on several interesting phenomena in warped compactifications of M theory, as presented at Strings 2000. The behavior of gauge fields in dimensional reduction from d+1 to d dimensions in various backgrounds is explained from the point of view of the holographic duals (and a point raised in the question session at the conference is addressed). We summarize the role of additional...

| The search for better and more robust performance of speech recognition systems is ongoing. Much of the improvement is likely to come from better acoustic feature analysis. In this letter, the results from a signiicant experiment are reported; these show how a warped-DFT analysis outperforms an LPC-cepstral analysis in a signiicant way, supporting results by other researchers for diierent rec...

With recent improved dense trajectory features (HOG, warped HOF, and warped MBH), we employ two advanced super vector methods, namely Fisher Vector (FV) and soft Vector of Locally Aggregated Descriptors (VLAD-K) to encode them separately. The two individual super vectors are concatenated into a Hybrid Super Vector, and a linear SVM classifier is used to predict labels. We achieve 87.46%1 in ave...
