The statistics of a passive scalar randomly emitted from a point source is investigated analytically. Our attention has been focused on the two-point equal-time scalar correlation function. The latter is indeed easily related to the spectrum, a statistical indicator widely used both in experiments and in numerical simulations. The only source of inhomogeneity/anisotropy is in the injection mech...

measuring salinity of water at different depths along six transacts at the mouth of the wetland and along five tributaries connecting the wetland to the sea the extent of caspian sea penetration into anzali wetland was determined. the results demonstrated a depth-dependent salinity gradient extending up to 10 kilometres into the wetland. a pattern of saltwater and freshwater interface is presen...

conclusions results show that trigger point injection therapy in patients suffering from chronic lumbosacral radiculopathy with trigger points can significantly improve their recovery, and conservative therapy may not be adequate. results out of 98 patients, 64 had trigger points. thirty-two patients were assigned to each group. pain scores (mean ± sd) in tp group was 7.12 ± 1.13 and in n group...

We address the “freeform optics” inverse problem of designing a reflector surface mapping prescribed source distribution light to far-field distribution, for finite source. When reduces point source, has support only on optics ray directions. In this setting, is well-posed arbitrary and target probability distributions. It can be recast as an Optimal Transportation been studied both mathematica...
