Diffusive nuclear burning in cooling simulations and application to new temperature data of the Cassiopeia A neutron star [PDF]
Mon. Not. R. Astron. Soc. 484, 974-988 (2019), 2019 A critical relation in the study of neutron star cooling is the one between surface temperature and interior temperature. This relation is determined by the composition of the neutron star envelope and can be affected by the process of diffusive nuclear burning (DNB), which occurs when elements diffuse to depths where the density and temperature are ...

Nuclear lipid droplets identified by electron microscopy of serial sections. [PDF]
, 2013 International audienceBACKGROUND: Recent studies have suggested that nuclear lipid droplets (LDs) are organized into domains similar to those of cytoplasmic LDs.

Dredge-up and envelope burning in intermediate mass giants of very low metallicity [PDF]
Astrophys.J. 605 (2004) 425-435, 2003 (abbreviated) The evolution of intermediate mass stars at very low metallicity during their final thermal pulse asymptotic giant branch phase is studied in detail. As representative examples models with initial masses of 4Msun and 5Msun with a metallicity of Z=0.0001 ([Fe/H] ~ -2.3) are discussed.

Immunocytochemistry of nuclear domains and Emery-Dreifuss muscular dystrophy pathophysiology
European Journal of Histochemistry, 2009 The present review summarizes recent cytochemical findings on the functional organization of the nuclear domains, with a particular emphasis on the relation between nuclear envelope- associated proteins and chromatin.

The SUN protein Mps3 is required for spindle pole body insertion into the nuclear membrane and nuclear envelope homeostasis. [PDF]
PLoS Genetics, 2011 The budding yeast spindle pole body (SPB) is anchored in the nuclear envelope so that it can simultaneously nucleate both nuclear and cytoplasmic microtubules. During SPB duplication, the newly formed SPB is inserted into the nuclear membrane.

Nuclear envelope laminopathies: evidence for developmentally inappropriate chromatin-nuclear envelope interactions [PDF]
, 2013 During terminal differentiation of cells, there is typically a transition of the nuclear envelope from the Lamin B protein to Lamin A/C proteins.

Ultradonut Topology of the Nuclear Envelope [PDF]
Biophysical Journal, 2016 Significance Lipid membranes exhibit a variety of morphologies tailored to perform specific functions of cells and their organelles. A unique lipid structure is the nuclear envelope which houses the genome and plays a vital role in genome organization and signaling pathways.

Chromosome positioning is largely unaffected in lymphoblastoid cell lines containing emerin or A-type lamin mutations [PDF]
, 2005 Gene-poor human chromosomes are reproducibly found at the nuclear periphery in proliferating cells. There are a number of inner nuclear envelope proteins that may have roles in chromosome location and anchorage, e.g. emerin and A-type lamins.

Some properties of doubly-degenerate stars [PDF]
arXiv, 2020 We investigate critical masses of and circular geodesics around doubly-degenerate stars (DDSs) which are composed of cold nuclear matter as well as cold Fermionic dark matter (DM). We here consider asymmetric dark Fermion with self-interaction as a DM candidate.
