Charged particle detection performances of CMOS pixel sensors produced in a 0.18 um process with a high resistivity epitaxial layer

open access: yes, 2013
The apparatus of the ALICE experiment at CERN will be upgraded in 2017/18 during the second long shutdown of the LHC (LS2). A major motivation for this upgrade is to extend the physics reach for charmed and beauty particles down to low transverse momenta.

Mitochondrial ribosomal protein L41 mediates serum starvation-induced cell-cycle arrest through an increase of p21WAF1/CIP1

open access: yesBiochemical and Biophysical Research Communications, 2005
Ribosomal proteins not only act as components of the translation apparatus but also regulate cell proliferation and apoptosis. A previous study reported that MRPL41 plays an important role in p53-dependent apoptosis. It also showed that MRPL41 arrests the cell cycle by stabilizing p27(Kip1) in the absence of p53.

NEID Reveals That the Young Warm Neptune TOI-2076 b Has a Low Obliquity

open access: yesThe Astrophysical Journal Letters, 2023
TOI-2076 b is a sub-Neptune-sized planet ( R = 2.39 ± 0.10 R _⊕ ) that transits a young (204 ± 50 MYr) bright ( V = 9.2) K-dwarf hosting a system of three transiting planets.

A spectroscopic examination of accretion diagnostics for near solar mass stars in IC 348 [PDF]

open access: yes, 2008
High-resolution optical and moderate-resolution near-infrared spectra were obtained for 40 near solar mass (~2.0-0.5 M⊙) members of the 2-3 Myr old cluster IC 348 in order to examine established accretion diagnostics and the coupling between inner disk ...

Heterobeltiosis and interrelationship of some of important quantitative traits in oilseed rape genotypes

open access: yesOpen Agriculture, 2019
Half diallel crosses of eight spring genotypes of oilseed rape (Brassica napus L.) were considered to evaluate heterobeltiosis effects of plant height, yield component characters, seed yield and harvest index.

Resolving Galactic-scale Obscuration of X-Ray AGNs at z ≳ 1 with COSMOS-Web

open access: yesThe Astrophysical Journal Letters, 2023
A large fraction of the accreting supermassive black hole population is shrouded by copious amounts of gas and dust, particularly in the distant ( z ≳ 1) universe.

A powerful and highly variable off-nuclear X-ray source in the composite starburst/Seyfert 2 galaxy NGC 4945 [PDF]

open access: yes, 1996
We report on a powerful and variable off-nuclear X-ray source in the nearby spiral galaxy NGC 4945. Two ROSAT PSPC observations show the source to brighten in 0.5--2.0 keV flux by a factor of about 9 on a time-scale of 11 months or less.

Identification of Mutations in Protein Kinase CKIIβ Subunit That Affect Its Binding to Ribosomal Protein L41 and Homodimerization

open access: yesBMB Reports, 2003
Protein kinase CKII is composed of two catalytic (alpha or alpha') subunits and two regulatory (beta) subunits. The CKIIbeta subunit is thought to mediate the tetramer formation and interact with other target proteins. However, its physiological function remains obscure.

Extra-planar X-ray emission from disc-wide outflows in spiral galaxies

open access: yes, 2018
We study the effects of mass and energy injection due to OB associations spread across the rotating disc of a Milky Way-type galaxy, with the help of 3D hydrodynamic simulations.

Reliable H∞ control for discrete-time piecewise linear systems with infinite distributed delays [PDF]

open access: yes, 2009
In this paper, the reliable H∞ control problem is investigated for discrete-time piecewise linear systems with time delays and actuator failures. The time delays are assumed to be infinitely distributed in the discrete-time domain, and the possible ...
