Gold nanoparticles were synthesized with seed mediated wet growth method. A coexistent system with gold nanorods and nanospheres was prepared. In-situ real-time small angle X-ray scattering (SAXS) and ultraviolet-visible (UV-vis) absorption were used to monitor the growth process of Au...

We explore the effects of spike-timing-dependent plasticity (STDP) on weak signal transmission in a noisy neural network. We first consider the network where an ensemble of independent neurons, which are subjected to a common weak signal, are connected in parallel to a single postsynaptic neuron...

The size dependent complexity of protein sequences in various families in the FSSP database is characterized by sequence entropy, sequence similarity and sequence identity. As the average length L<Subscript>f</Subscript> of sequences in the family increases, an increasing trend of the sequence entropy and a decreasing...</subscript>
