Febrile Seizures

Abstract

A door-to-door survey was carried out to screen a community of 14,010 people (Parsis living in colonies in Bombay, India) for possible neurological diseases. High school graduates, social workers, and a medical student administered a screening questionnaire that, in a pilot study, had a high sensitivity for identifying febrile seizures in children under the age of 14 years. Neurologists used defined diagnostic criteria to evaluate individuals positive on the screening survey. There were 1,581 children under the age of 14 years. Twenty-eight children (19 boys, 9 girls) suffered from febrile seizures (17.7/1,000 population). The present prevalence study is the first from India and suggests that, contrary to expectation, the frequency of febrile seizures may be no different in developing and developed countries.

Pseudoscalar meson electromagnetic form factor at high Q2 from full lattice QCD

“…It is important to understand the limitations of the perturbative QCD approach here, because the pion distribution amplitude inferred from F π (Q 2 ) is used in other calculations. They appear, for example, in light-cone sum rule calculations of the form factor at low q 2 for the exclusive weak decay B → π ν to determine V ub [52,53]. Figure 2 shows a curve (labelled PQCD 2) that uses a shape for the distribution amplitude φ ηs = (x(1 − x)) ζ at a scale Q/2 = 2GeV where x is the light-cone momentum fraction and ζ = 0.52(6) is chosen to agree with lattice QCD results for a 2 for the π [50] (results indicate only weak quark mass-dependence, so this should be a good approximation).…”

Status of |Vcb| and |Vub| CKM matrix elements

“…Refs. [74,75,76] and references within). The |V ub | estimate are generally higher than the corresponding lattice ones, but still in agreement, within the relatively larger theoretical errors.…”

$$B-S$$ B - S transition form-factors with the light-cone QCD sum rules

“…[9][10][11][12], the B − S form-factors are calculated with the LCSR in the leading order approximation, the perturbative O(α s ) corrections are neglected. Due to the lengthy calculations, only perturbative O(α s ) corrections to the twist-2 and twist-3 terms in the LCSR for the B − P, V form-factors [18][19][20][21][22][23][24][25][26] and perturbative O(α 2 s ) corrections to the twist-2 terms in the LCSR for the B − π form-factor [27] are studied up to now, where the P and V denote the light pseudoscalar and vector mesons, respectively. In this article, we study the B − S form-factors by taking into account the perturbative O(α s ) corrections to the twist-2 terms using the LCSR.…”
