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 ...

Evidence of strong dynamic core excitation in $^{19}$C resonant break-up [PDF]

, 2016
The resonant break-up of $^{19}$C on protons measured at RIKEN [Phys. Lett. B 660, 320 (2008)] is analyzed in terms of a valence-core model for $^{19}$C including possible core excitations.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Hydrodynamic behavior of resonant chamber of an oscillating column of water for Pacific Ocean conditions

Revista Facultad de Ingeniería Universidad de Antioquia, 2023
Wave energy converters (WEC) may be a promising option for extracting the energy available in the sea and oceans in a clean way. The oscillating water column (OWC) is one of the most applicable and well-known WEC systems.

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.

Role of Wood anomalies in optical properties of thin metallic films with a bidimensional array of subwavelength holes [PDF]

, 2003
Recents works deal with the optical transmission on arrays of subwavelength holes in a metallic layer deposited on a dielectric substrate. Making the system as realistic as possible, we perform simulations to enlighten the experimental data.

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

Gas Motion Study of Lya Emitters at z~2 Using UV and Optical Spectral Lines

, 2013
We present the results of Magellan/MMIRS and Keck/NIRSPEC spectroscopy for five Lya emitters (LAEs) at z=2.2 for which high-resolution FUV spectra from Magellan/MagE are available. We detect nebular emission lines including Ha on the individual basis and
