The Astrophysical Journal, 1990 Near-discontinuities in the density of a star, such as that encountered in the transition between a chromosphere and a corona, reflect acoustic waves and thereby partially contain them within the star. These reflections help to establish a resonant acoustic cavity with discrete characteristic frequencies, even for modes with frequencies above the ...

Dust Shells around OH/IR Stars [PDF]
Journal of Astronomy and Space Sciences, 1988 We have made new models for mass-losing OH/IR stars to explain the properties of the dust shells around them using more accurate information about the material in the shell and the physical processes including pulsations. We have applied our dust opacity

, 2014 In the age of Kepler and CoRoT, extended observations have provided estimates of stellar pulsation frequencies that have achieved new levels of precision, regularly exceeding fractional levels of a few parts in 104.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Benchmarking Differential Reddening in Front of Globular Clusters
The Astronomical JournalInterstellar extinction is a major obstacle in determining accurate stellar parameters from photometry near the Galactic disk. It is especially true for globular clusters at low galactic latitudes, which suffer from significant amounts of spatially ...

Stable higher order finite-difference schemes for stellar pulsation calculations
, 2013 peer reviewedContext: Calculating stellar pulsations requires a sufficient accuracy to match the quality of the observations. Many current pulsation codes apply a second order finite-difference scheme, combined with Richardson extrapolation to reach ...

FEBS Letters, EarlyView.An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Pulsation models of O-rich and C-rich long period variables
EPJ Web of Conferences, 2017 The intrinsic variability of luminous red giants is an observable providing important information about stellar structure and evolution. Our aim is to provide a solid theoretical background to the wide amount of data coming from present and future ...

Molecular Oncology, EarlyView.Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.
