Stromgren photometric survey in the Galactic anticenter direction
(2012-11-16)Aims. The main purpose is to map the radial variation of the stellar space density for the young stellar population in the Galactic anticenter direction in order to understand the structure and location of the Perseus ... -
Strong particle light absorption over the Pearl River Delta (south China) and Beijing (north China) determined from combined Raman lidar and Sun photometer observations
(2006-10-24)[1] Particle size and absorption properties have been determined from combined one-wavelength Raman lidar and Sun photometer measurements in the Pearl River Delta (South China) in October 2004, and in Beijing (North China) ... -
Strongly coupled heavy and light quark thermal motion from AdS/CFT
(2021-11-19)We give a pedagogical presentation of heavy and light probe quarks in a thermal plasma using the AdS/CFT correspondence. Three cases are considered: external heavy and light quarks undergoing Brownian motion in the plasma, ... -
A strongly star-forming group : three massive galaxies associated with a quasi-stellar object
(2011-06)We present here photometric redshift confirmation of the presence of large-scale structure around the z = 1.82 quasi-stellar object (QSO) RX J0941, which shows an overdensity of submillimetre (submm) sources. Radio imaging ... -
Structural analysis of divalent metals binding to the Bacillus subtilis response regulator Spo0F : the possibility for In vitro metalloregulation in the initiation of sporulation
(2005-10)The presence of a divalent metal ion in a negatively charged aspartic acid pocket is essential for phosphorylation of response regulator proteins. Here, we present metal binding studies of the Bacillus subtilis response ... -
Structural and thermal analyses in semiconducting and metallic zigzag single-walled carbon nanotubes using molecular dynamics simulations
(2024-02-09)Equilibrium molecular dynamics (EMD) simulations have been performed to investigate the structural analysis and thermal conductivity (λ) of semiconducting (8,0) and metallic (12,0) zigzag single-walled carbon nanotubes ... -
Structural Breaks and Convergence in the European Retail Banking Sector
(2011)The aim of this paper is to investigate the convergence process in the European retail banking sector by analysing monthly deposit and lending data sets for the household and non-financial corporations sectors, the two ... -
Structural characterisation and mechanical FE analysis of conventional and M-Wire Ni-Ti alloys used in endodontic rotary instruments
(2014)The purpose of this study is to understand how the M-WireTM alloy, a material used in many endodontic rotary files nowadays, conditions the mechanical flexibility of these instruments at body temperature. The alloys are ... -
Structural constraints and excess capacity : An international comparison of manufacturing firms
(2016-08-01)Excess capacity results in real and opportunity costs as well as lower factor productivity. Conventionally, variation in capacity utilisation rates has been explained with reference to the business cycles and market ... -
Structural Differences Between Healthy Subjects and Patients With Schizophrenia or Schizoaffective Disorder: A Graph and Control Theoretical Perspective
(2021-06-28)The coordinated dynamic interactions of large-scale brain circuits and networks have been associated with cognitive functions and behavior. Recent advances in network neuroscience have suggested that the anatomical ... -
Structural Dynamic Modelling of a Multi-Storey Shear Frame using Mass and Stiffness Addition
(2020-06-01)Designers of systems involved in high-speed operation and users of lightweight structures have realised that measurement of stress/strain properties are not sufficient and that dynamic measurement / analysis are necessary ... -
Structural features of a close homologue of L1 (CHL1) in the mouse: a new member of the L1 family of neural recognition molecules
(1996)We have identified a close homologue of L1 (CHL1) in the mouse. CHL1 comprises an N-terminal signal sequence, six immunoglobulin (Ig)-like domains, 4.5 fibronectin type III (FN)-like repeats, a transmembrane domain and a ... -
Structural Foundations of Social Resilience
(2020-10-01)This article aims to contribute to the theoretical development of the social resilience approach. Recognising the interface between resilience and poverty studies, it proposes a distinct role for resilience research from ... -
Structural insights into binding of small molecule inhibitors to Enhancer of Zeste Homolog 2
(2014-11)Enhancer of Zeste Homolog 2 (EZH2) is a SET domain protein lysine methyltransferase (PKMT) which has recently emerged as a chemically tractable and therapeutically promising epigenetic target, evidenced by the discovery ... -

Structural invariance, structural definability and the Galois theory of elementarily invariant structures
(University of Hertfordshire, 1997)Suppose A and B are two adequately described structures- can we decide whether and how A is interpretable in terms of B? The question itself is in need of interpretation, of course. In different contexts, the term ... -
A Structural Investigation of the Epstein—Barr (EB) Virus Membrane Antigen Glycoprotein, gp340
(1984-02)Epstein—Barr (EB) virus membrane antigen (MA) glycoprotein (gp340) purified by a molecular weight-based technique has been subjected to biochemical analysis. Following treatment with glycosidases or tunicamycin during ... -
Structural Optimization and Thermal Management with PCM-Honeycomb Combination for Photovoltaic-Battery Integrated System
(2022-05-25)Power lithium–ion batteries retired from the electric vehicles (EVs) are confronting many problems such as environment pollution and energy dissipation. Traditional photovoltaic (PV) battery systems are exhibiting many ... -
Structural Optimization of a Total Replacement Hip Prosthesis
(Newswood Limited, 2015)Planted articular joints replace bone articulation allowing the transfer of loads and articular displacements. However, hip prosthesis cannot guarantee the same dynamic friction coefficients of natural joints. The present ...
