Visual search for targets among distractors is more efficient if attention can be guided to targets by attributes like color. In real-world search, we guide attention using information about surfaces (e.g., paintings are on walls). We compare "classic" color guidance to surface guidance in "scenes" of cubes. When a target can lie on one of many surfaces, color guidance is effective but surface ...
When a gas of particles is placed in a confined environment such as a room or box, the particles can bounce off the wall creating a pressure. In fact, the system can readily be very well described by the ideal gas law PV = nRT, where P is the pressure, V is the volume, and T is the temperature. This means that if one increases the temperature while holding the volume fixed, the pressure will in...
The stochastic Loewner evolution is a recent tool in the study of two-dimensional critical systems. We extend this approach to the case of critical systems with continuous symmetries, such as SU(2) Wess-Zumino-Witten models, where domain walls carry an additional spin-1/2 degree of freedom.
A definitive answer to the question whether artery walls are incompressible is to our opinion not yet categorically provided. Experimental-based evidence on the level of compressibility in artery walls is not easily achieved because of the difficulties associated with the measurement of very small differences in volumes under physiological pressure in these biological tissues. Past experiments ...
We study both experimentally and theoretically the driven motion of domain walls in extended amorphous magnetic films patterned with a periodic array of asymmetric holes. We find two crossed-ratchet effects of opposite sign that change the preferred sense for domain wall propagation, depending on whether a flat or a kinked wall is moving. By solving numerically a simple phi(4) model we show tha...
Language in science is in the midst of change and appears dominated by two contradictory trends. Globalization of scientific English seems to promise greater international unity, while growth of field-specific jargon suggests communicational diaspora. Real in part, each trend is complex and multileveled, and includes elements of convergence and divergence, along with important implications for ...
