A formal method for approximating eigenvalues of the nonselfadjoint Zakharov–Shabat eigenvalue problem in the semiclassical scaling is described. Analyticity of the potential is assumed and appears to be crucial. The method involves finding appropriate paths between pairs of complex turning points, and reproduces the Y-shaped spectra observed by Bronski [Physica D 97 (1996) 376]. An application...

The notification rate for infectious syphilis (i.e. infection of less than 2 years duration) in Queensland has remained fairly static over the last 5 years but the pattern of infection appears to be changing (Figure 1). Between 2001 and 2005, the non-Indigenous rate climbed from 1.1 to 2.0 cases per 100,000 population, while the rate in the Aboriginal and Torres Strait Islander population acros...

We report on a simulation study of the performance of the North Tower (WTC-I) of the World Trade Center complex during the impact of American Airline Flight 11, on September 11, 2001. We discuss impact damage the structural core might have sustained and its possible behavior under structural and thermal loading. Our simulations indicate that the worst damage to the core structure was in stories...

in spite of the significant role of teachers in the efficacy of classroom management particularly in teaching english as a foreign language, the issue has not been addressed sufficiently especially in relation with other individual variables. hence, this study made an attempt to investigate the association between iranian efl teachers’ classroom management, reflective thinking and transformatio...

The one step hydroxylation of benzene has been performed over structured catalytic bed made of ZSM-5 coatings grown by hydrothermal synthesis on stainless steel grids. The catalysts demonstrated a 97% selectivity towards phenol formation at benzene conversion of 11%. In addition of achieving the same reactivity as over the traditional zeolitic fixed beds, these new catalytic packings present se...

Following the ideas of the axiomatic characterization of the Choquet integral due to [D. Schmeidler, Integral representation without additivity, Proc. Amer. Math. Soc. 97 (1986) 255–261] and of the Sugeno integral given in [J.-L. Marichal, An axiomatic approach of the discrete Sugeno integral as a tool to aggregate interacting criteria in a qualitative framework, IEEE Trans. Fuzzy Syst. 9 (2001...

Background: most studies of older populations in developed countries show a decrease in the prevalence of disabilities, and an increase in chronic diseases over the past decades. Data in the Netherlands, however, mostly show an increase in the prevalence of chronic diseases and mixed results with regard to the prevalence of disability. This study aims at comparing changes in the prevalence, as ...

BACKGROUND Analysis of primary healthcare datasets offers the possibility to increase understanding of the epidemiology of acute uncommon conditions such as anaphylaxis, but these datasets remain under-exploited. AIM To investigate recent trends in the recorded incidence, lifetime prevalence and prescribing of adrenaline for anaphylaxis in England. METHODS QRESEARCH is one of the world's la...
