We show that the distribution of search time follows a log normal distribution. We show that search outcome is the result of a race between scene parsing and target detection. Scene parsing guides and focuses search, but also leads to quitting without detection. Quitting is not simply the ...
Using computer simulations, we identify three distinct factors that contribute to increasing T cell search efficiency: 1) a lognormal distribution of step lengths, 2) motion that is directionally persistent over short time scales, and 3) heterogeneity in movement patterns. Furthermore, we show that...
The {0,1} seeding of the technol-ogy lattice is now replaced by draws from a lognormal distribution for technology 'difficulty'. Firms are rewarded for successful innovations by increases in their R&D budget. We compare two regimes. In the first, firms are fixed in a region of technology ...

Q is a random number that obeys a normal distribution. L is a 1×d identity matrix. When R<ST, it means that there are no predators around the foraging environment, and individual sparrows can perform extensive search operations. If R≥ST, it means that the sparrows in the population ...
As discussed previously, the values of κ are obtained from simulation, and their uncertainties are incorporated in the likelihood through log-normal constraints. The estimated contribution from QCD events in the CR is also included. A possible signal contamination, which can be up to 10% for ...
