Synthetic hydrogen spectra of prominence oscillations
, 2014 Context. Prominence oscillations have been mostly detected using Doppler velocity, although there are also claimed detections by means of periodic variations in half-width or line intensity.

Insertion of the FeB cofactor in cNORs lacking metal inserting chaperones
FEBS Letters, EarlyView.Nitric oxide reductase is an enzyme found in the bacterial denitrification pathway. The NOR active site contains a non‐heme iron, often, but not always inserted with the assistance of chaperones. Here, we study the insertion of FeB in the subfamily of cNORs lacking chaperones and found a putative channel, conserved in the family, perhaps enabling the ...

Stark-Zeeman Broadening of Spectral Line Shapes in Magnetized Plasmas
Atoms, 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 ...

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

Global Collapses and Expansions in Star-Forming Clouds
, 2009 Spectral molecular line profile observations of star-forming molecular clouds sometimes show distinct red asymmetric double-peaked molecular line profiles with weaker blue peaks and stronger red peaks.

Magnetic intensification of spectral lines [PDF]
Astronomy & 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

FEBS Letters, EarlyView.This study explores the distinct molecular mechanisms underlying Lynch syndrome‐associated and sporadic colorectal cancer (CRC). By highlighting the therapeutic potential of targeting the PI3K‐Akt pathway in Lynch syndrome‐associated CRC and the Wnt pathway in sporadic CRC, the findings open avenues for personalised treatment strategies, aiming to ...

Spectral Expansion for the Asymptotically Spectral Periodic Differential Operators [PDF]
arXiv, 2016 In this paper we investigate the spectral expansion for the asymptotically spectral differential operators generated in all real line by ordinary differential expression of arbitrary order with periodic matrix-valued ...
