This work is a first attempt at bringing first passage times of stochastic systems into wind engineering by suggesting the use of a first passage time map as a standard analysis tool in experimental wind engineering.
Because the virulence of the first-generation rabbit HEV was limited, we used virus recovered from the feces of rabbits inoculated with the GDC54 strain of HEV as a second passage inoculum for the further studies.
We have now confirmed these initial observations in experiments using hemi-brain extracts from these mice that showed accelerated disease after experimental challenge, thus representing a "second passage" of the disease, as is routinely performed to propagate prion strains in experimental models.
Results reveal that dramatic changes occur as early as first passage.
For cross-species transmissions, also referred to as first passage, weanling hamsters from each of the 6 hamster species were intracranially inoculated with 263K stock at a titer of 2 × 10 lethal dose for 50% per 50 µL of a 1% brain homogenate.
With this in mind, one may think of a 'diffusion delay' as the first passage time of a molecule into a predefined subset of the domain or possible chemical state.
noatunensis GM2212 isolate on VNTR stability was tested as follows: a frozen first passage culture of the GM2212 isolate was streaked for isolation on CHAB, one single colony was transferred in each passage for 10 passages.
(A ) Mean first passage time (MFPT) as a function of the initial distance to the target for both c-Myc (non-compact exploration; Df = 3, Dw = 2, and diffusion coefficient D = 9.8 μm/s) and P-TEFb (compact exploration; Df = 2.6, Dw = 3.3, and scale factor of the MSD fit D = 7.8).
At day 17, cells were passaged on collagen I-coated 12-well plates as described for the first passage.
RAD52 is required for recombination-dependent maintenance of telomeres in the absence of telomerase, and as expected, by the first passage the majority of rad52 ∆ est1 ∆ strains were growing poorly and never recovered (Mceachern and Haber 2006).
Starting from some initial state (x_{0}), the distribution of the amount of time required for a stochastic process to encounter a threshold for the first time is known as the first passage time distribution (FPTD).
