The S region of the H-2 complex controls the serum levels of two proteins, Ss and Sip, which are closely related antigenically (1-4). Several observations suggest that the Ss protein may be part of the complement system and homologous to C4. F(ab')2 fragments of antibody to Ss inhibit the hemolytic activity of mouse serum (5) and Ss antigenic determinants are incorporated into immune complexes ...

Consider a binary classification prediction problem. Training data are given and we denote them observations as T = {X,y} = {xi, yi}i=1, where xi ∈ R, yi ∈ {+1,−1} (accordingly X ∈ Rm×n). First, we will consider the case where the two classes are linearly separable. That is, by an n-dimensional decision boundary which is the result of an n + 1-dimensional hyperplane). Furthermore, since there c...

Reply to Nannini and Arias.

TO THE EDITOR— We thank Nannini and Arias for their interest in our article [1]. They raise several important issues in assessing the impact of emergency department occult Staphylococcus aureus bacteremia on patient outcomes [2]. Although 30-day mortality is a commonly used study endpoint in most bacteremia outcome researches, we agree that a 30-day follow-up period might be inadequate for pati...

ARIAS: Automated Retinal Image Analysis System

In this paper, a system for automated analysis of retinal images is proposed. This system segments blood vessels in retinal images and recognizes the main features of the fundus on digital color images. The recognized features were defined as blood vessels, optic disc, and fovea. An algorithm called 2D matched filters response has been proposed for the detection of blood vessels. Also, automati...
