Image classification is an important task in the remote sensing field. In a previous study, the authors presented a semi-automated supervised level set-based hyperspectral image segmentation algorithm (LSHSA) (Ball and Bruce, 2005). The LSHSA method used specialized speed functions created using pixel similarity and class discriminator functions. The pixel similarity function was based on an ex...

In this paper, a coplanar waveguide (CPW) fed hexagonal shape planar antenna has been considered for ultra-wide band (UWB). This antenna is then modified to obtain dual band rejection. The Wireless Local Area Network (WLAN) and Wireless Microwave Access (WiMAX) band rejections are realized by symmetrically incorporating a pair of L-shape slots within the ground plane as well as a couple of I-sh...

BACKGROUND The aim of the present study was to investigate the role of disengagement beliefs in smoking cessation. The association of disengagement beliefs with forward transition through the transtheoretical stages of change and self-reported quitting were examined, with and without adjusting for processes of change. METHODS A longitudinal survey was conducted among Dutch smokers, resulting ...

OBJECTIVE To replicate findings that risk-minimizing and self-exempting beliefs lower quit intentions, and to extend this by testing their capacity to prospectively predict smoking cessation. METHOD 13,324 adult (> or =18 years) cigarette smokers from the USA, Canada, UK, and Australia from one of the first three waves (2002-2004) of the International Tobacco Control 4-Country survey were emp...

OBJECTIVE To track national population indices of recall and response among smokers and recent quitters to an ongoing national televised anti-smoking campaign in Australia. METHOD National cross sectional population telephone surveys of adults. MAIN OUTCOME MEASURES Unprompted recall of advertising; recognition of advertising; campaign attributed encouragement to quit or stay quit; unprompt...

Although most smokers want to quit, the long-term success rate of quit attempts remains low; research is needed to understand the policy and environmental influences that can increase the success of cessation efforts. This paper uses regression methods to investigate self-reported exposure to policy and environmental influences on quit attempts, maintenance of a quit attempt for at least 6 mont...

BACKGROUND Smoking prevalence differs significantly across Europe. In addition, there are considerable differences in tobacco control activities across European countries. The relationship between prevalence and policy is under-researched. The present analysis examines the motivation to change smoking behaviour across 5 different European countries that differ considerably in their tobacco cont...

On the surface, the recent mobilization of opposition to the Stop Online Piracy Act (SOPA) over the internet appears to be yet another cyberactivism success. Yet, the antiSOPA movement should have been doomed to failure for two reasons. First, the issue was too abstract to mobilize local kinship and friendship groups. Second, because mass media interests were served by the bill, mass media was ...

Glutamate-inserting ochre suppressors have been identified among late-arising, spontaneous revertants of a hisG428 mutant of Salmonella typhimurium and an argE3 mutant of Escherichia coli. The S. typhimurium suppressors mapped in the tRNA2(Glu) gene gltU at 82 min; those in E. coli were found to be in tRNA2(Glu) genes gltW at 56 min, gltU at 85 min, and gltT at 90 min.
