Statutory union recognition provisions as stimulants to employer anti-unionism in three Anglo-Saxon countries
(2010)This article examines why employer opposition is stimulated by the introduction of statutory union recognition provisions in Britain, Ireland and the US. It examines the impact of the provisions for encouraging union ... -
STBC Based Pilot-Aided Channel Estimation Method for SFBC-OFDM Systems
(Liverpool John Moores University, 2014-06-23)In this paper, an iterative channel estimation algorithm with joint detection is proposed for Multiple Input Multiple Output (MIMO) systems combined with Orthogonal Frequency Division Multiplexing (OFDM) also known as ... -
STD-dependent and independent encoding of input irregularity as spike rate in a computational model of a cerebellar nucleus neuron
(2011)Neurons in the cerebellar nuclei (CN) receive inhibitory inputs from Purkinje cells in the cerebellar cortex and provide the major output from the cerebellum, but their computational function is not well understood. It has ... -
Steady-state nucleosynthesis throughout the Galaxy
(2021-06-01)The measurement and astrophysical interpretation of characteristic γ-ray lines from nucleosynthesis was one of the prominent science goals of the INTEGRAL mission and in particular its spectrometer SPI. Emission from 26Al ... -
Steiner Schools in England
(University of the West of England, 2005)The Department for Education and Skills (DfES) commissioned a research project to comprehensively map Steiner school education in England, identify and investigate good practice, explore the differences and commonalities ... -
Stellar (n,gamma) cross sections of p-process isotopes Part I: Pd-102, Te-120, Ba-130,Ba-132, and Dy-156
(2010-01)We have investigated the (n,gamma) cross sections of p-process isotopes with the activation technique. The measurements were carried out at the Karlsruhe Van de Graaff accelerator using the Li-7(p, n) Be-7 source for ... -
Stellar activity as a tracer of moving groups
(2013-04)We present the results of a study of the stellar activity in the solar neighborhood using complete kinematics (galactocentric velocities U, V, W) and the chromospheric activity index log R'(HK). We analyzed the average ... -
Stellar and Gas Kinematics in the core and bar regions of M100
(2005)Two-dimensional maps of the stellar and gas kinematics of the bar and starbursting circumnuclear region in the barred spiral galaxy M100 are presented. In this progress report, we present maps of the total intensity, mean ... -
Stellar and Gas Kinematics in the core and bar regions of M100
(American Institute of Physics (AIP), 2005)Two-dimensional maps of the stellar and gas kinematics of the bar and starbursting circumnuclear region in the barred spiral galaxy M100 are presented. In this progress report, we present maps of the total intensity, mean ... -
The Stellar and Gas Kinematics of the LITTLE THINGS Dwarf Irregular Galaxy NGC 1569
(2012-11)In order to understand the formation and evolution of Magellanic-type dwarf irregular (dIm) galaxies, one needs to understand their three-dimensional structure. We present measurements of the stellar velocity dispersion ... -
Stellar Atmospheric Parameters for Cool Dwarfs in Gaia Data Release 3
(2024-02-01)We provide a catalog of atmospheric parameters for 1,806,921 cool dwarfs from Gaia Data Release 3 (DR3) that lie within the range covered by LAMOST cool dwarf spectroscopic parameters: 3200 K < T eff < 4300 K, −0.8 < [M/H] ... -
Stellar Atmospheric Parameters of M-type Stars from LAMOST DR8
(2022-06-23)The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) Low Resolution Spectroscopic Survey (LRS) provides massive spectroscopic data of M-type stars, and the derived stellar parameters could bring vital ... -

Stellar chronology with white dwarfs in wide binaries
(Cambridge University Press, 2009)White dwarfs are the evolutionary end product of stars with low and intermediate masses. The evolution of white dwarfs can be understood as a cooling process, which is relatively well known at the moment;. For this reason, ... -
A stellar dynamical mass measurement of the black hole in NGC 3998 from Keck adaptive optics observations.
(2012-07-01)We present a new stellar dynamical mass measurement of the black hole in the nearby, S0 galaxy NGC 3998. By combining laser guide star adaptive optics observations obtained with the OH-Suppressing Infrared Imaging Spectrograph ... -
Stellar feedback as the origin of an extended molecular outflow in a starburst galaxy
(2014-12-04)Recent observations have revealed that starburst galaxies can drive molecular gas outflows through stellar radiation pressure. Molecular gas is the phase of the interstellar medium from which stars form, so these outflows ... -
Stellar feedback efficiencies: supernovae versus stellar winds
(2016-02-11)Stellar winds and supernova (SN) explosions of massive stars (`stellar feedback') create bubbles in the interstellar medium (ISM) and insert newly produced heavy elements and kinetic energy into their surroundings, possibly ... -
Stellar migrations and metal flows -- Chemical evolution of the thin disc of a simulated Milky Way analogous galaxy
(2020-07-01)In order to understand the roles of metal flows in galaxy formation and evolution, we analyse our self-consistent cosmological chemo-dynamical simulation of a Milky Way like galaxy during its thin-disc phase. Our simulated ... -
Stellar neutron capture cross sections of Pr and Dy isotopes
(1999-02)The neutron capture cross sections of Pr-141, Dy-160, Dy-161, Dy-161, Dy-163 and Dy-164 have been measured in Be energy range from 3 to 225 keV at the Karlsruhe 3.75 MV Van de Graaff accelerator. Neutrons were produced via ... -
Stellar neutron capture reactions at low and high temperature
(2022-11-08)The determination of astrophysical reaction rates requires different approaches depending on the conditions in hydrostatic and explosive burning. The focus here is on astrophysical reaction rates for radiative neutron ...
