Neurocysticercosis (NCC) is a biological marker of poverty and underdevelopment [1]. The frequency of this brain parasitic disease is probably high worldwide, as well as epilepsy; however, little is known about the natural history of the infection in humans. Both, NCC and epilepsy, are an increasing burden on the welfare and economy of developing countries [2]. This is why knowledge of these di...

We have analyzed the measurements of the end-to-end packet reordering by tracing UDP packets between 12 testboxes of RIPE NCC. We showed that reordering quite often happens in Internet. For bursts of 50 100-byte UDP packets, there were about 56% of all the streams arrived at the destinations out-of-order. We studied the extent of the reordering in these streams, and observed that most reordered...

In this paper, I present additional information for policy-makers and researchers to consider in response to the view proposed by Potts et al that “the pill is mightier than the sword.” I identify states with both high rates of terrorism and a youth bulge and discuss correlates of both these societal characteristics. The research examined supports the view that factors other than access to fami...

In the context of our ongoing search for the neuronal correlates of consciousness (Crick and Koch, 1998, 1999), I discuss Jackendoff’s „Intermediate Level Theory of Consciousness“ as well as related work of others, that implies that we are not directly conscious of our thoughts. I apply this hypothesis to the visual system of the macaque monkey and discuss possible experimental tests.

Many approaches to unconstrained face identification exploit small patches which are unaffected by distortions outside of their locality. However, small patches have limited discriminative ability, making accurate patch matching difficult. We propose a novel blockbased approach to exploit the greater discriminative information in larger areas, while maintaining robustness to local variations. A...

This paper describes a class of algorithms enabling efficient and exhaustive matching of a template into an image based on the Zero mean Normalized Cross-Correlation function (ZNCC). The approach consists in checking at each image position two sufficient conditions obtained at a reduced computational cost. This allows to skip rapidly most of the expensive calculations required to evaluate the Z...

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as refer...

Episodic memory relies on both recollection and familiarity; why these processes are differentially engaged during retrieval remains unclear. Traditionally, recollection has been considered necessary for tasks requiring associative retrieval, whereas familiarity supports recognition of items. Recently, however, familiarity has been shown to contribute to associative recognition if stimuli are "...

We present a formula for computing integrals over rectangles of arbitrary dimension in the special case that the size of the rectangles of interest is constant. Compared to the popular method of integral images, our approach reduces the amount of auxiliary memory and alleviates the effect of precision loss when computing large integral images. As an application of this technique we present a fa...
