Overview on Spectral Line Source Finding and Visualisation [PDF]

open access: yesPublications Astronomical Society of Australia, 2012
Here I will outline successes and challenges for finding spectral line sources in large data cubes that are dominated by noise. This is a 3D challenge as the sources we wish to catalog are spread over several spatial pixels and spectral channels.

Aβ42 promotes the aggregation of α‐synuclein splice isoforms via heterogeneous nucleation

open access: yesFEBS Letters, EarlyView.
The aggregation of amyloid‐β (Aβ) and α‐synuclein (αSyn) is associated with Alzheimer's and Parkinson's diseases. This study reveals that Aβ aggregates serve as potent nucleation sites for the aggregation of αSyn and its splice isoforms, shedding light on the intricate interplay between these two pathogenic proteins.

A comparison of field-line resonances observed at the Goose Bay and Wick radars [PDF]

open access: yesAnnales Geophysicae, 1997
Previous observations with the Goose Bay HF coherent-scatter radar have revealed structured spectral peaks at ultra-low frequencies. The frequencies of these spectral peaks have been demonstrated to be extremely consistent from day to day.

Archaeal protein containing domain of unknown function 2193 undergoes oligomeric reconfiguration upon iron–sulfur cluster binding

open access: yesFEBS Letters, EarlyView.
This work presents the characterization of MvoDUF2193, a Methanococcus voltae (Mvo) protein from the domain of unknown function (DUF) 2193 family. We demonstrate that MvoDUF2193 binds a single [4Fe–4S] cluster per subunit and that cluster occupancy regulates the transition from an apo tetramer to a [4Fe–4S] monomeric form. This structural transition is

Discrimination against interfering signals at the Poker Flat MST radar [PDF]

open access: yes, 1983
Several on line and off line data processing techniques are used to remove interfering signals due to ground clutter, aircraft, instrumental effects, and external transmissions from the desired atmospheric echoes of Mesosphere Stratosphere, Troposphere ...

Pulse phase and precession phase resolved spectroscopy of Her X-1: studying a representative Main-On with RXTE

open access: yes, 2013
We performed a detailed pulse phase resolved spectroscopy of the accreting binary X-ray pulsar Her X-1 in the energy range 3.5-75 keV and have established pulse phase profiles for all spectral parameters.

Stark-Zeeman Broadening of Spectral Line Shapes in Magnetized Plasmas

open access: yesAtoms, 2020
In this work, we studied the Lyman-alpha line in the presence of a magnetic field, such as the ones found at the edge of tokamaks. The emphasis is on the contribution of the motional Stark effect on line broadening, which may have comparable effects to ...

Magnetic intensification of spectral lines [PDF]

open access: yesAstronomy & Astrophysics, 2003
We present an in-depth investigation of the increase in equivalent width of saturated lines under the influence of strong magnetic fields, aptly called "magnetic intensification". Assuming 20 different Zeeman patterns (with the number of components ranging from 3 to 45) for a fictitious F II line at 4500A° in a 10000K, log g = 4.0 Kurucz atmosphere, we

Redox‐dependent binding and conformational equilibria govern the fluorescence decay of NAD(P)H in living cells

open access: yesFEBS Letters, EarlyView.
In this work, we reveal how different enzyme binding configurations influence the fluorescence decay of NAD(P)H in live cells using time‐resolved anisotropy imaging and fluorescence lifetime imaging microscopy (FLIM). Mathematical modelling shows that the redox states of the NAD and NADP pools govern these configurations, shaping their fluorescence ...

Electronic Spectral Functions for Quantum Hall Edge States

open access: yes, 1996
We have evaluated wavevector-dependent electronic spectral functions for integer and fractional quantum Hall edge states using a chiral Luttinger liquid model.
