A dedicated, non-symbolic, system yielding imprecise representations of large quantities (Approximate Number System, or ANS) has been shown to support arithmetic calculations of addition and subtraction. In the present study, 5-7-year-old children without formal schooling in multiplication and division were given a task requiring a scalar transformation of large approximate numerosities, presen...

In this paper we explore a time-predictable chip-multiprocessor (CMP) system based on single-path programming. To keep the timing constant, even in the case of shared memory access for the CMP cores, the tasks on the cores are synchronized with the time-sliced memory arbitration unit. 1 The Single-Path CMP System The main goal of our approach is to build an architecture that provides a combinat...

Using single-molecule optical-trapping techniques, we examined the force-induced dynamic behavior of a single nucleosome core particle. Our experiments using the DNA construct containing the 601 nucleosome-positioning sequence revealed that the nucleosome unravels in at least two major stages. The first stage, which we attributed to the unraveling of the first DNA wrap around the histone octame...
