In this paper a new wavelet shrinkage technique is proposed and investigated. When data consist of a multiplicity of related noisy signals, we propose a wavelet-based shrinkage estimation procedure to summarize all data components into a single regularized and representative signal (\base-line"). This fusion of information from di erent runs is done via Stein-type shrinkage rule resulting from ...

Activity-induced modification of neuronal connections is essential for the development of the nervous system and may also underlie learning and memory functions of mature brain. Previous studies have shown an increase in dendritic spine density and/or enlargement of spines after the induction of long-term potentiation (LTP). Using two-photon time-lapse imaging of dendritic spines in acute hippo...

Casting solidification brings to the shrinkage in the liquid state, solidification shrinkage and shrinkage in the solid state. Recently, technologies of die and gravity casting have increased the number of highly functional castings, which have been characterized with the very complex geometry. due to the different wall thickness in these castings, as well as the high solidification rates, prem...

Abstract Haloxylon ammodendron is an excellent windproof and sand-fixing species whose shrubs are widely cultivated in arid desert areas of northwest China but now at risk degradation shrinkage. Using the chlorophyll fluorescence image analysis technique, response photosystem II (PSII) photochemical efficiency non-photochemical quenching capacity to sediment-carrying wind sand-free (both 12 m s...
