The surface states of 3D topological insulators in general have negligible quantum oscillations when the chemical potential is tuned to Dirac points. In contrast, we find that Kondo can support with an arbitrarily large Fermi pinned point. We illustrate these surfaces give rise finite-frequency oscillations, which become comparable extremal area unhybridized bulk bands. show this occurs crystal...

In this paper, we present a new method for creating shadow texture atlas with which we can represent the self-shadow. Shadow texture atlas is a texture atlas with shadow information in each texel. Shadow texture is effective to represent high-quality shadow using the graphics hardware because it stores shadow information as color unlike shadow map which stores depth. However, it cannot represen...

Shadow fading is a well known problem in wireless sensor networks (WSN) and ad hoc networks since the communicating devices often are at street-level where the surrounding buildings often obstruct incoming radio waves. Therefore, accurately modeling shadow fading is an important requirement for the optimal design of such networks. Because the height of building is the most important parameter t...

Lateralization touches virtually every function we think makes us human and interacts fundamentally with development. Here we connect lateralized function to anatomical asymmetries, and connect those anatomical asymmetries to temporal asymmetries in development. Our differential encoding (DE) model (Cipollini, Hsiao, & Cottrell, 2012; Hsiao, Cipollini, & Cottrell, 2013; Hsiao, Shahbazi, & Cottr...

in a fictional movie, shadow is not only a technical and thematic concept, but also one of the most illustrative and expressing aesthetic elements of the movie. shadows vast dimensions have led to various discussions and studies along the history of cinema. the main theory of this essay is that a shadow is a comprehensible phenomenon whose interpretation and understanding are greatly essential ...

Shadow detection in real scene images is always a challenging but yet interesting area. Most shadow detection and segmentation methods are based on image analysis. This paper aimed to give a comprehensive and critical study of current shadow detection methods. Various approaches have been discussed related to shadow detection in images. The principles of these methods rely on intensity differen...

In this paper, head baffle and head shadow effects were measured at a front-oriented and at a back-oriented microphone in a hearing aid casing when worn by human subjects and when placed on a dummy head. Some differences in head baffle and head shadow effects were observed for the front-and back-oriented microphones in that greater head baffle effects were observed at the front microphone than ...

In this paper we present a novel image based algorithm to render visually plausible anti-aliased soft shadows in a robust and efficient manner. To achieve both high visual quality and high performance, it employs an accurate shadow map filtering method which guarantees smooth penumbrae and high quality anisotropic anti-aliasing of the sharp transitions. Unlike approaches based on pre-filtering ...
