Let T be a singular nonintegral operator; that is, it does not have an integral representation by a kernel with size estimates, even rough. In this paper, we consider the boundedness of commutators with T and Lipschitz functions. Applications include spectral multipliers of self-adjoint, positive operators, Riesz transforms of second-order divergence form operators, and fractional power of elli...

Large areas of Iran are under the influence of wind erosion thus it is important that we recognize three zones ofremoval, transportation and deposition. The deposition zone is very important due to more damages and tangibleeffects. In this study we try to obtain a comprehensive idea to Persian desert with use of laboratory facilities, remotesensing, GIS and field surveying. We survey 28 ergs in...

The purpose of this retrospective study was to report the results of iontophoretic corneal collagen crosslinking (I-CXL) with riboflavin and ultraviolet A irradiation in patients affected by keratoconus, each with thinnest pachymetry values of <400 μ (with epithelium) and not treatable using standard epithelium-off technique.Fifteen eyes of 15 patients affected by progressive keratoconus and wi...

Submitted for the MAR07 Meeting of The American Physical Society Resonant enhancement of absorption in the superlens LEONID ALEKSEYEV, ZUBIN JACOB, EVGENII NARIMANOV, Princeton University — The Veselago lens (also known as the super lens) [1], which is a slab made of left handed material with ε=-1 and μ=-1 has interesting properties like perfect lensing [2] and cloaking [3]. When a source is pl...

We embed the supersymmetric standard model of hybrid inflation based on the next-tominimal superpotential term λNHuHd supplemented by an inflaton term κφN2, into an extra-dimensional framework, in which all the Higgs fields and singlets live in the bulk, while all the matter fields live on the brane. All the parameters of the effective 4d model can then be naturally understood in terms of a fun...
