Circular Sound Wave Scattering Derivation for Acoustic Cloak Detection
Circular Sound Wave Scattering Derivation Acoustic Cloak Detection Classical Physics
2012/5/29
In this Letter we develop analytical formulations to describe sound scattering in lossless medium due to 2D circular wave incident on an acoustic cloak. A perfect acoustic cloak is reflectionless and ...
Probing Tissue Multifractality Using Wavelet based Multifractal Detrended Fluctuation Analysis: Applications in Precancer Detection
Fractal Multifractal detrended fluctuation analysis Phase contrast imaging Refractive index Cancer diagnosis
2011/8/4
Abstract: The refractive index fluctuations in the connective tissue layer (stroma) of human cervical tissues having different grades of precancers (dysplasia) was quantified using a wavelet-based mul...
Differing self-similarity in light scattering spectra: A potential tool for pre-cancer detection
Differing self-similarity light scattering spectra pre-cancer detection
2011/8/4
Abstract: The fluctuations in the elastic light scattering spectra of normal and dysplastic human cervical tissues analyzed through wavelet transform based techniques reveal clear signatures of self-s...
Detection of Chirality and Mutations of Knots and Links
chirality mutation Chern-Simons field theory invariants
2011/9/30
Abstract: In this brief presentation, we would like to present our attempts of detecting chirality and mutations from Chern-Simons gauge theory. The results show that the generalised knot invariants, ...
Detection of spin injection into a double quantum dot: Violation of magnetic-field-inversion symmetry of nuclear polarization instabilities
Detection of spin injection double quantum dot: Violation nuclear polarization instabilities
2010/11/19
In mesoscopic systems with spin-orbit coupling, spin-injection into quantum dots at zero magnetic eld is expected under a wide range of conditions. However, up to now, a viable approach for experimen...
Deriving Bell's nonlocality from nonlocality at detection
Deriving Bell nonlocality nonlocality detection
2010/10/18
It is argued that Bell’s nonlocality is a particular case of nonlocality at detection, which appears already in single-particle interference experiments. The unity of nonlocality and local causality i...
Quantum state engineering, purification, and number resolved photon detection with high finesse optical cavities
Quantum state high finesse optical
2010/3/10
We propose and analyze a multi-functional setup consisting of high finesse optical cavities, beam splitters, and phase shifters. The basic scheme projects arbitrary photonic two-mode input states onto...
Numerical detection of unstable periodic orbits in continuous-time dynamical systems with chaotic behaviors
Numerical detection unstable periodic orbits continuous-time dynamical systems chaotic behaviors
2009/11/3
An infinite number of unstable periodic orbits (UPOs) are embedded in a chaotic system which models some complex phenomenon. Several algorithms which extract UPOs numerically from continuous-time chao...

a monolithic optical cavity atom detection manipulation
2010/4/7
We study a Fabry-Perot cavity formed from a ridge waveguide on a AlGaAs substrate. We experimentally determined the propagation losses in the waveguide at 780 nm, the wavelength of Rb atoms. We have a...
Clock synchronization by remote detection of correlated photon pairs
Clock synchronization remote detection correlated photon pairs
2010/4/9
We present an algorithm to detect the time and frequency difference of independent clocks based on observation of time-correlated photon pairs. This enables remote coincidence identification in entang...
