This paper addresses the knowledge criticality question: what knowledge is critical to the focal task and therefore, needs to be retrieved. It argues that knowledge criticality is not an objective construct and that people’s prior task knowledge which consists of two dimensions: knowledge domain and expertise level, as well as social knowledge has an effect on what knowledge they perceive as cr...

We report the observation of negative magnetoresistance in the ferromagnetic semiconductor Ga1−xMnxAs, x=0.05–0.08, at low temperatures T 3 K and low magnetic fields 0 B 20 mT . We attribute this effect to weak localization. Observation of weak localization strongly suggests impurity band transport in these materials, since for valence band transport one expects either weak antilocalization due...

It is shown that the nature of compactification of extra dimensions in theories of large radius compactification can be explored in several processes at the Large Hadron Collider (LHC). Specifically it is shown that the characteristics of the Kaluza-Klein (KK) excitations encode information on the nature of compactification, i.e., on the number of compactified dimensions as well as on the type ...

Let Ω be a bounded simply connected domain in the complex plane, C. Let N be a neighborhood of ∂Ω, let p be fixed, 1 < p < ∞, and let û be a positive weak solution to the p Laplace equation in Ω ∩N. Assume that û has zero boundary values on ∂Ω in the Sobolev sense and extend û to N \ Ω by putting û ≡ 0 on N \ Ω. Then there exists a positive finite Borel measure μ̂ on C with support contained in ...

The hormone oxytocin is known to facilitate positive communication behaviors. In the current study, we aimed to examine how it affects the interpretation of verbal information during communication. We predicted oxytocin to promote the understanding of the socially most effortful dimension of appeal. After intranasal administration of oxytocin or a placebo, participants responded to a "four-ear ...

We analyze a cheap talk game, a-la Crawford and Sobel (1982), in a multidimensional state and policy space. A feature of the multidimensional state space is that communication on one dimension often reveals information on others. We show how this feature imposes bounds on communication.

The article describes communication system working on base of gravity waves. Such system of devices should work if the electromagnetic field curves space-time. Theoretical results shows that the artificial change of gravity of space-time curvature should observes in the distance much more bigger than dimension of transmitter antenna. The article end with discussion of details of technical prope...

The recent application of the principles of quantum mechanics to cryptography has led to a remarkable new dimension in secret communication. As a result of these new developments, it is now possible to construct cryptographic communication systems which detect unauthorized eavesdropping should it occur, and which give a guarantee of no eavesdropping should it not occur.

The frames of reference used by 4-, 6-, and 8-year-old children were studied in a spatial direction-giving task. Children were asked to specify verbally the location of a toy hidden under one of several identical cups. The child and listener sat facing each other at opposite ends of a room that had distinctive or nondistinctive landmarks proximal and distal to the hiding location. Location need...

let r be an associative ring with identity, c(r) be the category of com-plexes of r-modules and flat(c(r)) be the class of all at complexes of r-modules. we show that the at cotorsion theory (flat(c(r)); flat(c(r))−)have enough injectives in c(r). as an application, we prove that for each atcomplex f and each complex y of r-modules, exti (f,x)= 0, whenever ris n-perfect and i > n.
