It has long been conjectured that hydrodynamic interactions between beating eukaryotic flagella underlie their ubiquitous forms of synchronization; yet there has been no experimental test of this connection. The biflagellate alga Chlamydomonas is a simple model for such studies, as its two flagella are representative of those most commonly found in eukaryotes. Using micromanipulation and high-s...

conclusions stem cell therapies in wound care may lessen the morbidities associated with wound healing. an ideal method for the effective administration of stem cells for burn patients has not yet been elucidated. further comparison of the local and systemic effects in burn patients, associated with each route of stem cell delivery, needs to be performed. results application of cells to the bur...

A bistatic X-band experiment was successfully performed early November 2007. TerraSAR-X was used as transmitter and DLR’s new airborne radar system F-SAR, which was programmed to acquire data in a quasicontinuous mode to avoid echo window synchronization issues, was used as bistatic receiver. Precise phase and time referencing between both systems, which is essential for obtaining high resoluti...

this paper is concerned with the problem of synchronization for complex dynamic networks with state and coupling time-delays. therefore, larger class and more complicated complex dynamic networks can be considered for the synchronization problem. based on the lyapunov-krasovskii functional, a delay-independent criterion is obtained and formulated in the form of linear matrix inequalities (lmis)...

conclusions adc valuecould be a prognostic factor to monitor the response to therapy for patients with cervical cancer. the addition of dw-mri to the conventional mri protocolsconsiderably improved the diagnostic ability of mr imaging method for tumor evaluations. results studies had shown thatthe mean adc value of cervical carcinoma (1.110 ± 0.175 × 10-3 mm2/s)is significantly lower than that ...

one hundred female markhoz goats (42±5 kg) were used to investigate the ‘male effect’ on estrous synchronization and reproductive characteristics of female goat during the breeding season. this was carried out in three separate experiments. in the first experiment, forty female goats were used in 4 groups with different distance from the male goats (i.e. source of pheromone secretion); a1 (1 me...

An information-theoretic approach for studying synchronization phenomena in experimental bivariate time series is presented. "Coarse-grained" information rates are introduced and their ability to indicate generalized synchronization as well as to establish a "direction of information flow" between coupled systems, i.e., to discern the driving from the driven (response) system, is demonstrated u...

Harmonic phase-dispersion microscopy (PDM) is a new imaging technique in which contrast is provided by differences in refractive index at two harmonically related wavelengths. We report a new configuration of the harmonic phase-dispersion microscope in a Mach-Zehnder geometry as an instrument for imaging biological samples. Several improvements on the earlier design are demonstrated, including ...
