A unified framework for the orbital structure of bars and triaxial ellipsoids [PDF]

, 2015
We examine a large random sample of orbits in two self-consistent simulations of N-body bars. Orbits in these bars are classified both visually and with a new automated orbit classification method based on frequency analysis.

Hydrodynamic Investigation on a Land-Fixed OWC Wave Energy Device under Irregular Waves

Applied Sciences, 2022
The hydrodynamic response of a land-based oscillating water column (OWC) wave energy converter under various irregular wave conditions is investigated numerically. Based on the potential flow theory, a two-dimensional fully nonlinear numerical wave flume

Radio-frequency impedance measurements using a tunnel-diode oscillator (TDO) technique

, 1999
A resonant method based on a tunnel-diode oscillator (TDO) for precision measurements of relative impedance changes in materials, is described. The system consists of an effective self-resonant LC-tank circuit driven by a forward-biased tunnel diode ...

Photon-Assisted Quasiparticle Transport and Andreev Transport through an Interacting Quantum Dot

, 1999
Resonant tunneling through a quantum dot coupled to superconducting reservoirs in the presence of time-dependent external voltage has been studied. A general formula of the current is derived based on the nonequilibrium Green's function technique.

A Green's function approach to transmission of massless Dirac fermions in graphene through an array of random scatterers

, 2012
We consider the transmission of massless Dirac fermions through an array of short range scatterers which are modeled as randomly positioned $\delta$- function like potentials along the x-axis.

Quadratic invariants for discrete clusters of weakly interacting waves [PDF]

, 2013
We consider discrete clusters of quasi-resonant triads arising from a Hamiltonian three-wave equation. A cluster consists of N modes forming a total of M connected triads.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

On the resonances and polarizabilities of split ring resonators [PDF]

, 2005
In this paper, the behavior at resonance of split ring resonators SRRs and other related topologies, such as the nonbianisotropic SRR and the broadside-coupled SRR, are studied.
