In this study, we investigated temporal integration of disparity information for crossed and uncrossed stereopsis. Across three experiments, exposure duration thresholds were measured for stereoscopic stimuli created from dynamic random-dot stereograms. In Experiment 1, an investigation of disparity detection showed that detection thresholds were equal for(More)
We have tested the hypothesis which stipulates that only early-replicating genes are capable of expression. Within one cell type of Physarum - the plasmodium - we defined the temporal order of replication of 10 genes which were known to be variably expressed in 4 different developmental stages of the Physarum life cycle. Southern analysis of(More)
Molecular biology is now a routine tool in almost all biological research fields. With the exponential growth in the number of molecular biological techniques, there is a recognizable need for sensitive, accurate and precise quantitation of nucleic acids. We present here two complementary instruments designed for the quantitation of nucleic acids, the(More)
During the calendar years 1998–2002, 147 clear 8 nm diameter particle formation events have been identified at the SMEAR I station in Värriö, northern Finland. The events have been classified in detail according to the particle formation rate, growth rate, event starting time, different trace gas concentrations and pre-existing particle concentrations as(More)

ing for technical support. We would also like to thank James Ingram and Ian Howard for 18 technical assistance. The comments provided by the expert referees were greatly appreciated. Abstract 25 Humans can learn to manipulate objects with complex dynamics, including non-rigid 26 objects with internal degrees of freedom. The first aim of this study was to(More)
The concept of motor prediction was first considered by Helmholtz when trying to understand how we localise visual objects. To calculate the location of an object relative to the head, the central nervous system (CNS) must take account of both the retinal location of the object and also the gaze position of the eye within the orbit. Helmholtz's ingenious(More)
