Abstract We study the front of solution to F-KPP equation with randomized non-linearity. Under suitable assumptions on randomness including spatial mixing behavior and boundedness, we show that lags at most logarithmically in time behind corresponding linearized equation, i.e. parabolic Anderson model. This can be interpreted as a partial generalization Bramson’s findings (Bramson Commun Pure A...

Monkeys with lesions of perirhinal cortex (PR group) and monkeys with lesions of inferotemporal cortical area TE (TE group) were tested on a modified version of the delayed nonmatching to sample (DNMS) task that included very short delay intervals (0.5 sec) as well as longer delay intervals (1 min and 10 min). Lesions of the perirhinal cortex and lesions of area TE produced different patterns o...

We consider the porous medium equation on a compact Riemannian manifold and give a new proof of the contraction of its semigroup in the Wasserstein distance. This proof is based on the insight that the porous medium equation does not increase the size of infinitesimal perturbations along gradient flow trajectories, and on an Eulerian formulation for the Wasserstein distance using smooth curves....

A lac promotor mutant was constructed by filling in the protruding ends of the HpaII site located within the lac promotor. The mutation, named M42, is a two base pair insertion that changes the distance between the -10 and -35 regions from 18 to 20 residues. The activity of the mutant promotor measured in vivo is 15% of the wild-type promotor. The M42 promotor is sensitive to the catabolite rep...

The current study investigated the effect of distance on medium preferences in interpersonal communication. Five experiments showed that people's preference for using pictures (vs. words) is increasingly higher when communicating with temporally, socially, or geographically proximal (vs. distal) others. In contrast, preference for words is increasingly higher when communicating with those who w...

Frugivores are highly variable in their contribution to fruit removal in plant populations. However, data are lacking on species-specific variation in two central aspects of seed dispersal, distance of dispersal and probability of dispersal among populations through long-distance transport. We used DNA-based genotyping techniques on Prunus mahaleb seeds dispersed by birds (small- and medium-siz...
