The Importance of Dendritic Mitochondria in the Morphogenesis and Plasticity of Spines and Synapses
TL;DR: The proper intracellular distribution of mitochondria is assumed to be critical for normal physiology of neuronal cells, and increasing dendritic mitochondrial content or mitochondrial activity enhances the number and plasticity of spines and synapses.
Journal ArticleDOI

TL;DR: The Tropical Rainfall Measuring Mission (TRMM) was launched on 27 November 1997, and data from all the instruments first became available approximately 30 days after the launch as mentioned in this paper, and much progress has been made in the calibration of the sensors, the improvement of the rainfall algorithms, and applications of these results to areas such as data assimilation and model initialization.
Journal ArticleDOI
Rain profiling algorithm for the TRMM precipitation radar
TL;DR: In this paper, an algorithm that estimates the instantaneous profiles of the true radar reflectivity factor and rainfall rate from the radar reflectivities profiles observed by the precipitation radar (PR) onboard the TRMM satellite is presented.
Journal ArticleDOI
Rapid and persistent modulation of actin dynamics regulates postsynaptic reorganization underlying bidirectional plasticity.
TL;DR: It is shown here that tetanic stimulation causes a rapid, persistent shift of actin equilibrium toward F-actin in the dendritic spines of rat hippocampal neurons, which enlarges the spines and increases postsynaptic binding capacity.
Journal ArticleDOI
Heterogeneous Photocatalytic Decomposition of Phenol over TiO2 Powder
TL;DR: In this paper, the photocatalytic decomposition of phenol in oxygenated aqueous suspensions of lightly-reduced anatase TiO2 was investigated at the optimum pH 3.5.
