Let P be a set of n points in the plane that determines at most n/5 distinct distances. We show that no line can contain more than O(npolylog(n)) points of P . We also show a similar result for rectangular distances, equivalent to distances in the Minkowski plane, where the distance between a pair of points is the area of the axis-parallel rectangle that they span. The problem and its backgroun...

The regularization parameter choice is a fundamental problem in Learning Theory since the performance of most supervised algorithms crucially depends on the choice of one or more of such parameters. In particular a main theoretical issue regards the amount of prior knowledge needed to choose the regularization parameter in order to obtain good learning rates. In this paper we present a paramete...

New measurements on cross sections in $e^+e^-\to J/\psi\pi^+\pi^-$, $h_c\pi^+\pi^-$, $D^0D^{*-}\pi^++c.c.$, $\psi(2S)\pi^+\pi^-$, $\omega\chi_{c0}$ and $J/\psi\eta$ channels have been carried out by BESIII, Belle BABAR collaborations, also the $D_s^*\bar D_s^*$ channel. We perform extensive numerical analyses combining all these data available, together with those $D\bar D^*$ $D^*\bar channels....

Several studies showed that the index of nasopharyngeal carcinoma (NPC) cell growth could be used to assess carcinogenesis interaction factor, development and prognosis NPC. Cell proliferation always assessed with Ki-67 protein expression test. This research was conducted study correlation between cervical lymphoid node status in NPC clinical manifestation asses progressivity on patients. cross...

Introduction: Ectopic pregnancy is an emergency in obstetric wards and a significant cause of maternal morbidity and mortality. Incidences of ectopic pregnancy are increasing. Life can be saved with quickness and alertness. Objective: The objective of this study is to find out and evaluate the incidence, clinical presentation, risk factors, and management outcomes of ectopic pregnancies at Sri ...

We review our algebraic framework for linear boundary problems (concentrating on ordinary differential equations). Its starting point is an appropriate algebraization of the domain of functions, which we have named integro-differential algebras. The algebraic treatment of boundary problems brings up two new algebraic structures whose symbolic representation and computational realization is base...
