We study the occupation statistics of galaxies in dark matter haloes using galaxy groups identified from the 2-degree Field Galaxy Redshift Survey with the halo-based group finder of Yang et al. (2004b). The occupation distribution is considered separately for early and late type galaxies, as well as in terms of central and satellite galaxies. The mean luminosity of the central galaxies scales ...

The large majority of extragalactic star cluster studies done to date have essentially used two or three-passband aperture photometry, combined with theoretical stellar population synthesis models, to obtain age estimates. The accuracy to which this can be done depends on the number of observations through different (broad-band) filters available as well as, crucially, on the actual wavelength ...

In the title mol-ecule, C(13)H(15)ClF(2)N(2)O, the piperazine ring is in a chair conformation with the 2,4-difluoro-benzyl and chloro-acetyl substituents in equatorial positions.

BACKGROUND Hepatitis C virus (HCV) infection represents a worldwide health threat that still needs efficient protective vaccine and/or effective drug. The traditional medicine, such as camel milk, is heavily used by the large sector of HCV patients to control the infection due to the high cost of the available standard therapy. Camel milk contains lactoferrin, which plays an important and multi...

The Coupling Loss Factors (CLF) to describe the vibration transmission at junctions in context of Statistical Energy Analysis (SEA) are determined. Out-of-plane energy (bending waves) and in-plane (treating transverse shear waves quasi longitudinal as a single subsystem) well their interactions considered. CLF values obtained from inverse SEA problem where energies input powers computed numeric...

We solve the feedback stabilization problem for a tank, with friction, containing liquid modeled by viscous Saint-Venant system of Partial Differential Equations. A spill-free exponential is achieved, robustness to wall friction forces. Control Lyapunov Functional (CLF) methodology two different functionals employed. These determine specific parameterized sets which approximate state space. The...

Ciliary neurotrophic factor (CNTF) receptor controls a pathway supporting the differentiation and survival of a wide range of neural cell types during development and in adulthood. Cardiotrophin-like cytokine (CLC)-cytokine-like factor 1 (CLF) composite cytokine is a second ligand for the CNTF alpha-component receptor (CNTFRalpha). This composite cytokine is built on the structural model of IL-...

BACKGROUND Public and stakeholder engagement can improve the quality of both research and policy decision making. However, such engagement poses significant methodological challenges in terms of collecting and analysing input from large, diverse groups. OBJECTIVE To explain how online approaches can facilitate iterative stakeholder engagement, to describe how input from large and diverse stak...

The chromatin modifying Polycomb group (PcG) and trithorax group (trxG) proteins are central regulators of cell identity that maintain a tightly controlled balance between cell proliferation and cell differentiation. The opposing activities of PcG and trxG proteins ensure the correct expression of specific transcriptional programs at defined developmental stages. Here, we report that the chroma...
