Abstract Radial profiles of density fluctuations and the radial electric field, E r , have been measured using Doppler reflectometry during post-pellet enhanced confinement phase achieved, under different heating power levels magnetic configurations, 2018 W7-X experimental campaign. A pronounced -well is with local values as high ?40 kV m ?1 in range ? ? 0.7–0.8 phase. The maximum intensity sca...

the binary and ternary codes spanned by the rows of the point by block incidence matrices of some 2-designs and their complementary and orthogonal designs are studied. a new method is also introduced to study optimal codes.

we present an approach to design of fault tolerant computing systems. in this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. code combining techniques are very effective, which one of these codes are turbo codes. the algorithm-based fault tolerance techniques that to detect errors rely on the c...

Recently, codes over some special finite rings especially chain rings have been studied. More recently, codes over finite non-chain rings have been also considered. Study on codes over such rings or rings in general is motivated by the existence of some special maps called Gray maps whose images give codes over fields. Quantum error-correcting (QEC) codes play a crucial role in protecting quantum ...

The main purpose of the RESR storage ring in the FAIR project is the accumulation of high intensity antiproton stacks, mainly for the HESR storage ring, but also for the deceleration in the NESR storage ring which provides antiprotons for low energy experiments in the FLAIR experimental area. The high efficiency of antiproton production required for high luminosity experiments in the HESR is ac...

BACKGROUND Although healthcare administrative data are commonly used for traumatic brain injury (TBI) research, there is currently no consensus or consistency on the International Classification of Diseases Version 10 (ICD-10) codes used to define TBI among children and youth internationally. This study systematically reviewed the literature to explore the range of ICD-10 codes that are used to...

We study the spatial circular restricted problem of three bodies in the light of Nekhoroshev theory of stability over large time intervals. We consider in particular the Sun-Jupiter model and the Trojan asteroids in the neighborhood of the Lagrangian point L 4. We find a region of effective stability around the point L 4 such that if the initial point of an orbit is inside this region the orbit...
