To control reaching, the nervous system must generate large changes in muscle activation to drive limb toward target, and also make smaller adjustments for precise accurate behavior. Motor cortex controls arm through projections diverse targets across central system, but it has been challenging identify roles of cortical specific targets. Here, we selectively disrupt cortico-cerebellar communic...

ABSTRACT The non-resonant Kuiper belt objects between the 3:2 and 2:1 Neptunian mean motion resonances can be largely divided a cold classical (CCB) hot (HCB). A notable difference these two subpopulations is prevalence of widely spaced, equal-mass binaries in CCB, much smaller but non-zero number HCB. primary reason for this binary rate remains unclear. Here using N-body simulations we examine...

Similarity concept, finding the resemblance or classifying some groups of objects and study their common properties has been the interest of many researchers. Basically, in the studies the similarity between two objects or phenomena, 2-similarity in our words, has been discussed. In this paper, we consider the case when the resemblance or similarity among three objects or phenomena of a set, 3-...

Previous research has investigated the effects of nontarget objects (NTOs) on reach trajectories, but their effects on eye-hand coordination remain to be determined. The current investigation utilized an eye-hand coordination paradigm, where a reaching and grasping task was performed in the presence of an NTO positioned exclusively in the right or left workspace of each right-handed participant...

In this paper the c = 1 matrix model deformed by a 1/x piece is discussed. Tachyon correlation functions are calculated up to genus two using methods similar to those for the undeformed case. The possible connection with the two dimensional black hole is also considered. In particular, restrictions on naked singularities imposed by the matrix model are found. CERN-TH.6916/93 June 1993

We investigate the occurrence and nature of naked singularities in the Szekeres space-times. These space-times represent irrotational dust. They do not have any Killing vectors and they are generalisations of the Tolman-Bondi-Lemâıtre space-times. It is shown that in these space-times there exist naked singularities that satisfy both the limiting focusing condition and the strong limiting focus...

In multi-agent systems, norms are usually considered rules that can be violated by agents. The reasons for norm violation are usually bounded to agents utility evaluation gain versus possible fee but with our proposal we depict a scenario in which norms are open or vague. Agent’s can interpret norms in different ways, according to their knowledge but also according with their own interpretation...

Most automated graphics generation systems employ either a constructive or a parametric graphics synthesis approach. Constructive graphics synthesis is a deductive approach that builds visual presentations from scratch by gluing together the most basic visual variables. Conversely, parametric graphics synthesis defines a set of parametrized visual models and interprets the information to be pre...
