Three competing hypotheses have been proposed for the cortical representation of the blind spot. These are: (i) the regions surrounding the blind spot maintain their spatial values; (ii) the opposite sides of the blind spot are represented adjacently at the cortex, so that the blind spot is "sewn-up"; and (iii) the blind spot is sewn-up with compensation occurring in the immediate surround of t...

In this paper we address the problem of reliably fitting parametric and semi-parametric models to high density spot array images obtained in genetic expression experiments. The goal is to measure the amount of genetic material at specific spot locations. A lot of spots can be modelled accurately by a Gaussian shape. In order to deal with highly overlapping spots we use robust M-estimators. When...

Energy-efficient query dissemination plays an important role for the lifetime of sensor networks. In this work, we consider probabilistic flooding for query dissemination and develop an analytical framework which enables the base station to predict the energy consumed and the nodes reached according to the rebroadcast probability. Furthermore, we devise a topology discovery protocol that collec...

Commodity loans are presented as an interpretation of spreads between spot and futures prices in commodity markets. This interpretation suggests an alternative to convenience yield as an explanation for the existence of large positive differences between spot and futures prices that are inconsistent with the usual arbitrage arguments. A model is presented in which an owner of a stock of a commo...

The Canary archipelago comprises seven main volcanic islands and several islets that form a chain extending for ~ 500 km across the eastern Atlantic, between latitudes 27°N and 30°N, with its eastern edge only 100 km from the NW African coast (Figures 1 & 2). The Canary Islands developed in a geodynamic setting characterized by Jurassic oceanic lithosphere formed during the fi rst stage of open...

This research examines whether precious metals futures serve as a price discovery vehicle for spot market movement. The spot price serves as a price discovery tool for silver. The co-integration test shows that silver, futures and spot prices are co-integrated and there exists one co-integration equation. The Granger causality test shows that there is no bi-causal relationship between futures a...

BACKGROUND AND PURPOSE A spot sign is a bright spot on computed tomography angiography source images, which is predictive of hematoma growth in spontaneous intracerebral hemorrhage, although the cause of the spot sign is unclear. Our aim was to investigate the spot sign seen on computed tomography angiography and a striate artery, which is a presumed site of intracerebral hemorrhage bleeding or...
