In Experiment 1 rats had to escape from a kite-shaped pool by swimming to a submerged escape platform in a right-angled corner. The two walls creating this corner were white and the two walls creating the opposite, incorrect, right-angled corner were black. The rats were then trained in a square pool with two white walls forming one corner and two black walls forming the opposite corner. The pl...

We numerically investigate the transport of a suspended overdamped Brownian particle which is driven through a two-dimensional rectangular array of circular obstacles with finite radius. Two limiting cases are considered in detail, namely, when the constant drive is parallel to the principal or the diagonal array axes. This corresponds to studying the Brownian transport in periodic channels wit...

A Lagrangian study of two-dimensional turbulence for two different geometries, a periodic and a confined circular geometry, is presented to investigate the influence of solid boundaries on the Lagrangian dynamics. It is found that the Lagrangian acceleration is even more intermittent in the confined domain than in the periodic domain. The flatness of the Lagrangian acceleration as a function of...

Domain walls in multiferroics can exhibit intriguing behaviors that are significantly different from the bulk of the material. We investigate strong magnetoresistance in domain walls of the model multiferroic BiFeO3 by probing ordered arrays of 109° domain walls with temperature- and magnetic-field-dependent transport. We observe temperature-dependent variations in the transport mechanism and m...

In this Letter, we consider a liquid mixture confined between two thermally conducting walls subjected to a stationary temperature gradient. While in a one-component liquid nonequilibrium fluctuation forces appear inside the liquid layer, nonequilibrium fluctuations in a mixture induce a Casimir-like force on the walls. The physical reason is that the temperature gradient induces large concentr...

The subject of creativity may be one of the most misunderstood topics in management. We tend to equate creativity with pure artists, with those who are seemingly endowed with a mystical ability to make aesthetic sense out of color, shape and form. In the manager’s world, creativity is typically viewed as limited to picking out the art for the walls of a new office or selecting a designer to dev...

By analyzing sorption isotherm curves of surface treated MCM-41 samples, it is noticed that if the nanopore size is relatively small, the end group dominates the solid-liquid interaction and the influence of the side group is relatively weak, which can be attributed to the confinement effect of nanopore walls.
