We use TDEV at [tau] = 1 day, which is an established metric for estimating time transfer noise when the dominant noise type is white phase noise or flicker phase noise.
Measurement Uncertainties (nanoseconds) Uncertainty Component Best Case Worst Case Typical [U.sub.A], TDEV, [tau] = 1 d 0.7 5 2 [U.sub.B], Calibration 1 4 2 [U.sub.B], Coordinates 1 25 3 [U.sub.B], Environment 2.5 4 3 [U.sub.B], Multipath 1.5 5 2 [U.sub.B], Ionosphere 1 3.5 2 [U.sub.B], Ref.
These calibrations are typically stable to about 0.2 ns (TDEV at [tau] = 1 day) and have good repeatability.
Figure 9 shows the time stability (TDEV) of seven SIMTN participants during the last six months of 2009 for averaging periods ranging from 10 minutes to about one week.
The bundled product, CodeWarrior for NINTENDO GAMECUBE - TDEV Developer Edition, is expected to begin shipping in late February.
By combining the new TDEV hardware with its CodeWarrior development tools, Metrowerks is able to provide GAMECUBE developers with a network capable development kit that is significantly less expensive compared to existing development hardware for Nintendo GAMECUBE, which currently lacks network capability.
TDEV is essentially a consumer GAMECUBE unit with network capability, which allows developers to share a TDEV unit with multiple hosts.
TelcoBridges brands include: Tmedia (VoIP media gateways), Tdev (development platform) and Tmonitor (real-time network monitoring equipment.
It has for instance been shown that the concentration of tumor-derived extracellular vesicles (tdEVs) in the blood of metastatic cancer patients correlates with their probability of survival.
Still, before tdEVs can reliably be used in the clinic, they need to be more closely studied, which is a significant challenge due to: 1) their very small size, and 2) the vast number of other particles in blood which have a very similar size.
A collaboration between the UT's Medical Cell BioPhysics group (MCBP) and Applied Microfluidics for BioEngineering Research group (AMBER), together with Wageningen University has led to the development of a platform for the reliable isolation of tdEVs followed by their individual multi-parametric characterization using scanning electron microscopy (SEM), Raman spectroscopy and atomic force microscopy (AFM) to acquire comprehensive information on the isolated particles.
