An affine equivariant version of the nonparametric spatial conditional median (SCM) is constructed, using an adaptive transformation-retransformation (TR) procedure. The relative performance of SCM estimates, computed with and without applying the TR—procedure, are compared through simulation. Also included is the vector of coordinate conditional, kernelbased, medians (VCCMs). The methodology i...

We study a generalization of the classical median finding problem to batched query case: given an array of unsorted n items and k intervals in the array, the goal is to determine the median in each of the intervals in the array. We give an algorithm that uses O(n log k) comparisons and show a matching lower bound of Ω(n log k) comparisons for this problem.

Introduction: International travelers are exposed to health risks and may transmit infections before, during, or after travel. Travelers are expected to take vaccinations prior to travel. The current study assessed the factors associated with the practice of pre-travel vaccination among travelers departing through Addis Ababa Bole International Airport after their stay in Ethio...

Previous work has shown that nicotine facilitates brain stimulation reward (BSR) but that the maximum effect obtainable with nicotine is similar to that seen with compounds having a low addiction liability (e.g., caffeine, diphenhydramine, pseudoephedrine). Two studies further explored nicotine’s effects on BSR using a threshold-tracking procedure. Male, Long-Evans rats were implanted with stim...

a case of primary malignant non-hodgkin's lymphoma of the breast is reported. this is the first well-documented case of breast lymphoma in our institution and also in iran. the diagnosis of primary breast lymphoma requires the presence of lymphomatous infiltration in close ass, tissue in patients with neither previous lymphoma nor concurrent lymphoma in another site. there is no definite c...

Introduction Injection of the dopaminergic neurotoxin 6-hydroxydopamine (6-OHDA) into the striatum or medial forebrain bundle (MFB) is classically used to model Parkinsonism, but is increasingly used in a range of disease models [1]. Standard histological techniques are generally used to study the development and extent of the lesion, but it is not possible to use these techniques in-vivo. MRI ...

postoperative low cardiac output states are a major cause of postoperative mortality in infants and children following corrective cardiac surgery or congenital heart defects. whole body hypothermia has been used since 2001 in the management of these low output states when they are refractory to conventional modes of therapy. from december 2001 to april 2006, 25 cases were included in this study...
