On the Detection of (Habitable) Super-Earths Around Low-Mass Stars Using Kepler and Transit Timing Variation Method
Planetary Systems
2011/10/9
We present the results of an extensive study of the detectability of Earth-sized planets and super-Earths in the habitable zones of cool and low-mass stars using transit timing variation method. We ha...

Galaxies: dwarf — Galaxies: Local Group — Galaxies: structure — Galaxies: stellar content — Galaxies: ISM —Galaxies: individual
2011/10/8
We present deep V and I photometry of the isolated dwarf galaxy VV124=UGC4879, obtained from archival images taken with the Hubble Space Telescope - Advanced Camera for Surveys. In the color-magnitude...
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, ...
Influence of Doppler Bin Width on GNSS Detection Probabilities
GNSS acquisition Doppler bin width receiver operating characteristics
2011/9/1
Abstract: The acquisition stage in GNSS receivers determines Doppler shifts and code phases of visible satellites. Acquisition is thus a search in two continuous dimensions, where the digital algorith...
Detection of a single cobalt microparticle with a microfabricated atomic magnetometer
single cobalt microparticle microfabricated atomic magnetometer Instrumentation and Detectors
2011/8/3
Abstract: We present magnetic detection of a single, 2 {\mu}m diameter cobalt microparticle using an atomic magnetometer based on a microfabricated vapor cell. These results represent an improvement b...
Mass Loss, Destruction and Detection of Sun-grazing and -impacting Cometary Nuclei
comet sun impact sun-grazing radiation collisions
2011/9/30
Incoming sun-grazing comets almost never re-emerge, but no final destruction event has ever been observed, nor sun-impactor destruction theory developed. We seek analytic models of comet nucleus destr...
Potential Biases in the Detection of Planetary Systems with Large Transit Timing Variations
methods: data analysis – planetary systems – planets and satellites: detection –techniques: photometric
2011/9/29
The Transit Timing Variations (TTVs) technique provides a powerful tool to detect additional planets in transiting exoplanetary systems. In this paper we show how transiting planets with significant T...
Sparse aperture masking at the VLT I. Faint companion detection limits for the two debris disk stars HD 92945 and HD 141569
Instrumentation: high angular resolution – Stars: planetary systems – Stars: individual
2011/9/29
Observational data on companion statistics around young stellar systems is needed to flesh out the formation pathways for extrasolar planets and brown dwarfs. Aperture masking is a new technique that ...

2011/8/3
Abstract: Modularity maximization is the most popular technique for the detection of community structure in graphs. The resolution limit of the method is supposedly solvable with the introduction of m...
Evidence-Based Filters for Signal Detection: Application to Evoked Brain Responses
Evoked Brain Responses Bayesian Evidence Brain Machine Interface Optimum Filters
2011/8/3
Abstract: Template-based signal detection most often relies on computing a correlation, or a dot product, between an incoming data stream and a signal template. Such a correlation results in an ongoin...
