Totally accretive operators [PDF]
Proceedings of the American Mathematical Society, 1988 Let A A be a (possibly unbounded) linear operator on a Banach space. We show that, when A A generates a uniformly bounded strongly continuous semigroup { e − t

How Much Mass do Supermassive Black Holes Eat in their Old Age?
, 2005 We consider the distribution of local supermassive black hole Eddington ratios and accretion rates, accounting for the dependence of radiative efficiency and bolometric corrections on the accretion rate.

X-Shooter study of accretion in Chamaeleon I: II. A steeper increase of accretion with stellar mass for very low mass stars? [PDF]
, 2017 The dependence of the mass accretion rate on the stellar properties is a key constraint for star formation and disk evolution studies. Here we present a study of a sample of stars in the Chamaeleon I star forming region carried out using the VLT/X ...

The role and implications of mammalian cellular circadian entrainment
FEBS Letters, EarlyView.At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Accretion of low angular momentum material onto black holes: 2D magnetohydrodynamical case
, 2003 We report on the second phase of our study of slightly rotating accretion flows onto black holes. We consider magnetohydrodynamical (MHD) accretion flows with a spherically symmetric density distribution at the outer boundary, but with spherical symmetry

Resumption of mass accretion in RS Oph [PDF]
, 2007 The latest outburst of the recurrent nova RS Oph occurred in 2006 February. Photometric data presented here show evidence of the resumption of optical flickering, indicating re-establishment of accretion by day 241 of the outburst.

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10
FEBS Letters, EarlyView.Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Granitoids of the Ufaley Block: Geodynamic environments, age, sources, problems
Литосфера, 2016 There are complex of data about composition, age, isotopic parameters for granites from the Ufaley block, which is situated in the accretion zone on the boundary between the Urals and the East European platform.
