Introduction Perfusion is the term applied to capillary blood flow in tissue. Since the blood carries oxygen and nutrition to the tissue through the capillaries, perfusion is important in maintaining tissue viability. The study of brain perfusion has clinical applications due to the changes in perfusion associated with several neurological diseases. Diagnosis, lesion characterisation and follow...

This paper presents dynamic standby control (DSC) with voltage keeper for further standby power reduction. As compared to the reported DSC, the new modified DSC can be kept deeply cut-off with negative overdrive voltage as well. Besides, a bootstrapped voltage keeper directly recharges the boosted node of power gate, which prevents leakage current during the recharging period. However, total st...

Dysspondyloenchondromatosis (DSC) is a rare skeletal dysplasia that has currently been classified into the group of spondylometaphyseal dysplasias. To date, only 12 affected individuals have been reported. All cases are sporadic, and the etiology remains unknown. Distinctive features of DSC are anisospondyly and enchondroma-like lesions in the metaphyseal and diaphyseal portions of the long tub...

This note contributes to the technical nature of dynamic surface control (DSC) based on a class of strict-feedback nonlinear systems. The DSC technique prevents the complexity problem in integrator backstepping control (IBC). Yet, the stability results obtained by existing DSCs are conservative, and consequently, cannot fully reveal the technical nature of DSC. By the exploitation of the singul...

Low-frequency activity within the oculomotor system helps bridge sensation and action. Given ocular stability, low-frequency activity sustained by some neurons within the intermediate and deep superior colliculus (dSC) is assumed to be separated from motor output. However, the dSC is an orienting structure and the influence of low-frequency dSC activity at other effectors remains untested. We s...
