This paper presents an extensive electro-thermal characterisation of latest generation Silicon Carbide (SiC) power MOSFETs under Unclamped Inductive Switching (UIS) conditions. Tests are carried out to thoroughly understand the single pulse avalanche ruggedness limits of commercial SiC MOSFETs and assess their ageing under repetitive stress conditions. Both a functional and a structural charact...

The purpose of our study was to determine whether active musical engagement alleviates decline in inhibitory control due to cognitive aging. Given that musical training in young adults has been shown to improve attentional performance, we can expect this benefit to persist for older adults as well. With the help of the stop-signal procedure, we measured response inhibition of young and older ad...

The presence of repetitive elements can create serious problems for sequence analysis, especially in the case of homology searches in nucleotide sequence databases. Repetitive elements should be treated carefully by using special programs and databases. In this paper, various aspects of SINE (short interspersed repetitive element) identification, analysis and evolution are discussed.

A novel theorem linking reflectional symmetry and rotational symmetry has been established in this paper. This theorem constrains that, for a rotationally symmetric image with K>1 fold(s) (K-RSI), its number of reflection-symmetric axes must be either K or zero. The novel constraint theorem provides the guidance for the procedure of symmetry detection. It has been demonstrated by the experiment...

Simple repetitive DNA sequences in the eukaryotic genome frequently alter in length. In wild-type strains, we find that transcription through a repetitive poly GT tract destabilizes the tract four- to ninefold. In mismatch repair-deficient yeast strains, simple repeats are very unstable. High levels of transcription in such strains destabilize repetitive tracts an additional two- to threefold.

Introduction Exposures to low grade oxidative stress has become a common phenomenon, in these days of increasing environmental stress. Therefore, it becomes extremely relevant to investigate the factors determining the anti-apoptotic influence of repetitive stress and to document whether repetitive or chronic use of naturally occurring compounds influence the antiapoptotic outcome of repetitive...
