Fast Characterization of Dispersion and Dispersion Slope of Optical Fiber Links using Spectral Interferometry with Frequency Combs [PDF]
We demonstrate fast characterization (~1.4 microseconds) of both the dispersion and dispersion slope of long optical fiber links (~25 km) using dual quadrature spectral interferometry with an optical frequency comb.

Estimating growth parameters and growth variability from length frequency data using hierarchical mixture models [PDF]
AbstractAnalysis of length frequency distributions from surveys is one well-known method for obtaining growth parameter estimates where direct age estimates are not available. We present a likelihood-based procedure that uses mixture models and the expectation–maximization algorithm to estimate growth parameters from length frequency data (LFEM).

A Hybrid Brain-Computer Interface Based on Visual Evoked Potential and Pupillary Response
Brain-computer interface (BCI) based on steady-state visual evoked potential (SSVEP) has been widely studied due to the high information transfer rate (ITR), little user training, and wide subject applicability. However, there are also disadvantages such

Operating LISA as a Sagnac interferometer
A phase-locking configuration for LISA is proposed that provides a significantly simpler mode of operation. The scheme provides one Sagnac signal readout inherently insensitive to laser frequency noise and optical bench motion for a non-rotating LISA ...

The MULTIFAN method was used to analyse a series of monthly length-frequency distributions of the squat lobster Cervimunida johni Porter (1903) (Galatheidae), for the estimation of growth and age composition in the fishing area off Coquimbo (29°59’S-71 ...

Observational evidence of resonantly damped propagating kink waves in the solar corona
In this Letter we establish clear evidence for the resonant absorption damping mechanism by analyzing observational data from the novel Coronal Multi-Channel Polarimeter (CoMP).

Besøk på sykehjem. En kvantitativ studie av sykehjemsbeboeres besøkshyppighet
Social contact is essential for the well-being of the nursing home residents.Visiting frequency in nursing homes is rarely investigated. The purpose of this study was to map the number of visits for nursing home residents. Nursing students collected data
