This paper presents an interactive 3D modeling system that realizes a new method for modeling 3D objects using non-instrumented hand gestures. Our model representation is based on a mesh library, which is optimized not only for real-time rendering, but also accommodates for changes of both vertex positions and mesh connectivity in real time. For performing the gesture interaction, the user’s ha...

Single-layer of 1T$'$ phase WTe$_2$ provides a rich platform for exotic physical properties such as nonlinear Hall effect and high-temperature quantum spin hall transport. Utilizing continuum model diagrammatic method, we calculate the second harmonic conductivity monolayer 1T$'$-WTe$_2$ modulated by an external vertical electric field electron doping. We obtain finite helicity Faraday rotation...

The density functional theory (DFT) method combined with B3LYP and B3PW91 hybrid were utilized for geometrical optimization, vibrational frequencies electronic spectral study. levels of the time dependent-DFT 6–311+G(d, p) basis set have been used to determine highest occupied molecular orbital (HOMO) – lowest unoccupied (LUMO) energies, absorption wavelengths, properties (total energy gap) 4-(...

circularly-polarized antenna is built based on new siw(substrate integrated waveguide)structure which contains cavity-backed resonator and a conventional polarized ring with twosquare slits in inner and outer ring that differ 90° at position and is proposed for right-handedcircular polarization (rhcp) and fabricated in two separate layers. a broadband impedancebandwidth of 13.9% and a rhcp axia...

Continuum solvation methods are frequently used to increase the efficiency of computational methods to estimate free energies. In this paper, we have evaluated how well such methods estimate the nonpolar solvation free-energy change when a ligand binds to a protein. Three different continuum methods at various levels of approximation were considered, viz., the polarized continuum model (PCM), a...

How the visual system detects surface reflectance - lightness - has puzzled researchers for centuries. A new study of contexts that capture the characteristic luminance range of natural scenes rules out a long-standing theory of lightness perception.

We have monitored the polarized radiation of the Type IIb SN 1993J in M81 over a period of 41 days, starting from 7 days after the explosion on 1993 March 27.5 (UT). Our data show clear evidence that the intrinsic continuum polarization of SN 1993J evolved from being essentially negligible on April 3–4, to a peak value of ∼ 1% in late April 1993, and started to decline by the middle of May. The...

In order to protect their food from competitors, ball-rolling dung beetles detach a piece of dung from a pile, shape it into a ball, and roll it away along a straight path [1]. They appear to rely exclusively on celestial compass cues to maintain their bearing [2-8], but the mechanism that enables them to use these cues for orientation remains unknown. Here, we describe the orientation strategy...
