The microsphere technique has been used to follow changes in collateral blood flow as a function of time and to relate acute changes in collateral flow to subsequent myocardial necrosis after coronary occlusion. However, flow studies in chronic preparations are complicated by an apparent loss of microspheres from necrotic myocardium. Preocclusion or control flow measured 2-4 days after coronary...
The mindless act of swatting a mosquito on the hand poses a remarkable challenge for the brain. Given that the primary somatosensory cortex maps skin location independently of arm posture [1, 2], the brain must realign tactile coordinates in order to locate the origin of the stimuli in extrapersonal space. Previous studies have highlighted the behavioral relevance of such an external mapping of...
Differential 2.2μm (K-band) luminosity functions are presented for a complete sample of 1570 nearby (Vgsr ≤ 3000 km/s, where Vgsr is the velocity measured with respect to the Galactic standard of rest), bright (K ≤ 10 mag), galaxies segregated by visible morphology. The K-band luminosity function for late-type spirals follows a power law that rises towards low luminosities whereas the K-band lu...
Data warehouse systems integrate data from heterogeneous sources. These sources are autonomous in nature and change independently of a data warehouse. Owing to changes in data sources, the content and the schema of a data warehouse may need to be changed for accurate decision making. Slowly changing dimensions and temporal data warehouses are the available solutions to manage changes in the con...
Abstract Target and limit reference points are fundamental management components used to define sustainable harvest strategies. Maximum Sustainable Yield (MSY) the precautionary principle underpin many points. Non-proxy based on MSY in age-based single-species assessments depend stock–recruitment (SR) relationship, which can display complex variability. Current ignore persistent dynamic change ...
