We propose a method of extracting explanatory text of images from HTML files based both on retrieval of similar images and expansion of keywords using co-occurrence. Images in web pages often have their explanatory text in the same pages. Such explanatory text includes important keywords that explain the corresponding image. It is therefore reasonable to put these keywords to the image for fulf...

In Leung et al. (2017), we provide evidence that Drosophila transposons have been major contributors to the expansion of the Drosophila ananassae fourth chromosome (Muller F element) arms. Dunning Hotopp and Klasson agree with this finding, but they take exception to our second conclusion, that lateral gene transfer (LGT) from theWolbachia endosymbiont of D. ananassae (wAna) had only a minor ro...

PURPOSE To compare and contrast the physical characteristics of balloon catheter systems used for temporary cerebrovascular occlusion. METHOD Commonly used temporary occlusion systems were evaluated to determine: (a) balloon compliance; (b) balloon diameter versus volume; (c) balloon pressure versus volume; (d) simulated vessel wall pressure versus volume; (e) balloon failure volume; and (f) ...

We compare the Riemann–Liouville fractional integral (fI) of a function f(z) with the Liouville fI of the same function and show that there are cases in which the asymptotic expansion of the former is obtained from those of the latter and the difference of the two fIs. When this happens, this fact occurs also for the fractional derivative (fD). This method is applied to the derivation of the as...

We show that the formation of large-scale structures through gravitational instability in the expanding universe can be fully described through a path-integral formalism. We derive the action S[f ] which gives the statistical weight associated with any phase-space distribution function f(x,p, t). This action S describes both the average over the Gaussian initial conditions and the Vlasov-Poisso...

We consider scalar field theory in a changing background field. As an example we study the simple case of a spatially varying mass for which we construct the semiclassical approximation to the propagator. The semiclassical dispersion relation is obtained by consideration of spectral integrals and agrees with the WKB result. Further we find that, as a consequence of localization, the semiclassic...

In 1967 Durrmeyer introduced a modiication of the Bernstein polynomials as a selfadjoint polynomial operator on L 2 0; 1] which proved to be an interesting and rich object of investigation. Incorporating Jacobi weights Berens and Xu obtained a more general class of operators, sharing all the advantages of Durrmeyer's modiication, and identiied these operators as de la Vall ee{Poussin means with...

A wide variety of scientiic settings have to do with indirect noisy measurements. We are interesting in some object f(t) but the data is accessible only about some transform (Kf)(t), where K is some linear operator, and (Kf)(t) is in addition corrupted by noise. Recovering f(t) from indirect observations, one faces a Statistical Linear Inverse Problem (SLIP). The usual linear methods for SLIPs,...

KUNS-2121 YNU-HEPTh-07-103 The unpolarized virtual photon structure functions F γ 2 (x,Q , P ) and F γ L(x,Q , P ) are investigated in perturbative QCD for the kinematical region Λ ≪ P 2 ≪ Q, where −Q(−P ) is the mass squared of the probe (target) photon and Λ is the QCD scale parameter. In the framework of operator product expansion supplemented by the renormalization group method, the definit...
