Impervious surface area (ISA) is an important parameter for many studies such as urban climate, urban environmental change, and air pollution; however, mapping ISA at the regional or global scale is still challenging due to the complexity of impervious surface features. The Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) data have been used for ISA mapping, but...
OBJECTIVES We sought to identify the frequency of incomplete stent apposition (ISA) in sirolimus-eluting stents (SES) and clarify its findings and clinical sequelae. BACKGROUND Late-acquired ISA has been reported in bare-metal stents (BMS) and brachytherapy and recently in drug-eluting stents. However, the characteristics of late ISA in SES have not been clarified. METHODS From the SIRIUS t...
BACKGROUND The clinical impact of late incomplete stent apposition (ISA) for drug-eluting stents is unknown. We sought to prospectively investigate the incidence and extent of ISA after the procedure and at 6-month follow-up of paclitaxel-eluting stents in comparison with bare metal stents (BMS) and survey the clinical significance of ISA over a period of 12 months. METHODS AND RESULTS TAXUS ...
AIM A comparison study was conducted to explore the best internationally available adjuvant that could be used in production of a highly potent foot and mouth disease (FMD) vaccine, that could stimulate a strong immune response and possibly give greater protection against FMD. MATERIALS AND METHODS Four experimental batches of trivalent FMD vaccine were prepared with different available oil a...
The Theory of Planned Behaviour model (Ajzen, 1985) was used to determine whether long-term experience with Intelligent Speed Adaption (ISA) prompts a change in speed related cognitions. The study examines data collected as part of a project examining driver behaviour with an intervening but overridable ISA system. Data was collected in four six-month field trials. The trials followed an A-B-A ...
Information Security Awareness: Its Antecedents and Mediating Effects on Security Compliant Behavior
Information security awareness (ISA) is referred to as a state of consciousness and knowledge about security issues and is frequently found to impact security compliant behavior. However, to date we know little about the factors influencing ISA and its mediating effect on behavior. Our study addresses these gaps. We propose a research model that studies ISA’s institutional, individual, and envi...
ncomplete stent apposition (ISA), also known as stent alapposition, is defined most simplistically as the absence f contact between stent struts and the vessel wall not verlying a side branch. Incomplete stent apposition can ccur at the time of stent implantation—acute ISA—which ight either resolve or persist at follow-up (late-persistent SA). Patients without ISA at the time of stent implantai...
Independent subspace analysis (ISA) that deals with multidimensional independent sources, is a generalization of independent component analysis (ICA). However, all known ISA algorithms may become ineffective when the sources possess temporal structure. The innovation process instead of the original mixtures has been proposed to solve ICA problems with temporal dependencies. Here we show that th...
BACKGROUND Lack of re-endothelialization and neointimal coverage on stent struts has been put forward as the main underlying mechanism leading to late stent thrombosis. Incomplete stent apposition (ISA) has been observed frequently in patients with very late stent thrombosis after drug eluting stent implantation, suggesting a role of ISA in the pathogenesis of this adverse event. The aim of thi...
