The structure and dynamics of GRB jets
(2007)There are several lines of evidence which suggest that the relativistic outflows in gamma-ray bursts (GRBs) are collimated into narrow jets. The jet structure has important implications for the true energy release and the ... -
Structure and dynamics of the kinase IKK-β – A key regulator of the NF-kappa B transcription factor
(2011)The inhibitor κB kinase-β (IKK-β) phosphorylates the NF-κB inhibitor protein IκB leading to the translocation of the transcription factor NF-κB to the nucleus. The transcription factor NF-κB and consequently IKK-β are ... -
Structure and expression of an inhibitor of fungal polygalacturonases from tomato
(1994-07-01)A polygalacturonase inhibitor protein (PGIP) was characterized from tomato fruit. Differential glycosylation of a single polypeptide accounted for heterogeneity in concanavalin A binding and in molecular mass. Tomato PGIP ... -
Structure and realization of pole-shared switched-current complex wavelet filter
(2015-07-24)A pole-shared switched-current complex wavelet filter structure with follow-the-leader feedback configuration is proposed for synthesizing the real and imaginary approximation functions with the same poles. The double-sampling ... -
Structure generation and design of multiple loop feedback OTA-grounded capacitor filters
(1997)This paper addresses the structure generation, analysis and synthesis of multiple loop feedback OTA-C filters. A systematic approach is proposed for all-pole filters, and the generation and design of minimum component ... -
Structure Health Monitoring of Composites Joint Reinforce by Acoustic Emission based Smart Composite Fasteners
(2022-08-31)This paper proposed an Acoustic Emission (AE) based Smart Composite Fastener (SCF) concept for health monitoring of bonded/bolted composite single lap joints. The SCF was made of 3D-printed continuous carbon fibre reinforced ... -
The Structure of Avoidance Following Trauma : Development and Validation of the Posttraumatic Avoidance Scale (PAS)
(2013-06)Avoidance is a key maintenance factor in traumatic reactions but currently no satisfactory measures of it exist. Here we develop and validate a multi-dimensional measure of trauma-related avoidance across two samples. In ... -
The structure of employee compensation in Saudi Arabia : the case of chemical and petrochemical industries
(University of Hertfordshire, 2005)This study examines the wage differentials and wage discrimination among employees in the chemical and petrochemical industries in Saudi Arabia. The context of segmentation is discussed through a detailed examination of ... -
The Structure of Ghrelin
(2007)The structure of ghrelin, a 28-residue octanoylated peptide hormone, is only known up to the level of primary structure identifying an active core of residues 1-5 or 1-4 including octanoyl-Ser3 as necessary to elicit ... -
The structure of the HIV-1 Vpu ion channel: modelling and simulation studies
(2001-06-06)Vpu is an 81 amino acid auxiliary protein in HIV-1 which exhibits channel activity. We used two homo-pentameric bundles with the helical transmembrane segments derived from FTIR spectroscopy in combination with a global ... -
Structure of the Influenza C virus CM2 protein transmembrane domain obtained by site-specific infrared dichroism and global molecular dynamics searching
(2000-02-11)The 115-residue protein CM2 from Influenza C virus has been recently characterized as a tetrameric integral membrane glycoprotein. infrared spectroscopy and site-directed infrared dichroism were utilized here to determine ... -
The structure of the merging RCS 231953+00 supercluster at z ~ 0.9
(2013-05-10)The RCS2319+00 supercluster is a massive supercluster at z = 0.9 comprising three optically selected, spectroscopically confirmed clusters separated by <3Mpc on the plane of the sky. This supercluster is one of a few known ... -
The structure of the outer Galactic disc as revealed by IPHAS early A stars
(2010)This study is an investigation of the stellar density profile of the Galactic disc in the anticentre direction. We select over 40 000 early A stars from INT/WFC Photometric Hα Survey of the Northern Galactic Plane (IPHAS) ... -
The structure of the Sagittarius stellar stream as traced by blue horizontal branch stars
(2011-04-20)We use a sample of blue horizontal branch (BHB) stars from the Sloan Digital Sky Survey Data Release 7 to explore the structure of the tidal tails from the Sagittarius Dwarf Galaxy. We use a method yielding BHB star ... -
