Our purpose is to nd a suciently wide model denition including classical systems (signed-digit notation, linear numeration systems, p-adic numbers, symmetric level

Interestingly, after removal of the endo- thelium thrombin caused contractile responses in coronary arteries as observed in the present study [11,14] , which may be due to

As children get older (and calculation procedures would become more automatized), we predicted that dRTs would become more positive for addition problems (i.e., an increase in

Furthermore, analyzing the number of lane changes (per kilometer per hour) as function of the density in the origin lane and in the target lane, we find, as

For this study the framework considered to characterise number sense is composed by the following compo- nents: (1) understand the meaning of numbers; (2) rec- ognise the relative

It is known [5] that in this case there are (almost surely) at least two distinct optimal matchings for each instance of the problem, the ordered matching and the Dyck matching

The location of the rake relative to the measurement area has little effect on the measured mean speed, but the particle concentration decreases as the distance is increased.

Between 2005 and 2008, West Baltimore residents collaborated with the Maryland Department of Transportation, the Maryland Transit Administration, the Baltimore
