The Pohang Accelerator Laboratory (PAL) is developing a self amplification of spontaneous emission (SASE) based free electron laser (FEL) for X-ray coherent photon sources. The PAL developed a prototype undulator that had a 5.0 m magnetic length and

Synchronization of the coupled neuronal oscillator network is analyzed, focusing on the role of multiple connections with different time delays and on the dependence of synchronization on the distribution of time delays. It is shown that multiple con

Methylosinus trichosporium OB3b oxidized methane to methanol in the presence of a high concentration of Cu2+. Further oxidation of methanol to formaldehyde was prevented by adding 200 mM NaCl which acted as a methanol dehydrogenase H inhibitor. The b

The simplified models of neural networks based on biophysical Hodgkin–Huxley neurons are studied with a focus on coherent-phase dynamics. In our approach, each neuron is considered as a nonlinear oscillator, and collective dynamics of a mesoscopic

Recently, the phenomena of stochastic resonance (SR) have attracted much attention in the studies of the excitable systems under inherent noise, in particular, nervous systems. We study SR in a stochastic Hodgkin-Huxley neuron under Ornstein-Uhlenbec

Synchrony and clustering in phase dynamics of two and three Hodgkin–Huxley neurons coupled globally by excitatory synapses with a time delay have been studied by numerical simulations and bifurcation analysis. In particular, we have obtained phase

The deterministic conserved threshold transfer process, which is a variant of the conserved threshold transfer process modified in a way as that hopping of a particle is to be deterministic, is proposed. The critical behavior of the model is investig

The two scaling relations in absorbing phase transitions, nu_||=beta/theta and z=nu_||/nu_(perpendicular), are studied for a conserved lattice gas model. The critical indices calculated elaborately from the all-sample average density of active partic
