Visual working memory is characterised by a limited storage capacity. Given this storage limitation, selection of behaviourally relevant objects based on locations, features or object category, is crucial. We conducted behavioural and ERP experiments to investigate location-based selection of multiple targets for storage in visual working memory, with a change detection paradigm. In the first e...

Sensory-substitution prosthetic systems are based on the idea of substituting visual stimulation with stimulation from another intact sense such as audition or touch. Although such systems have been studied for almost 40 years (Bach-y-Rita 1968), they are still poorly understood. Here we ask whether we learn to perceive simple spatial properties using The vOICe (Meijer 1992), a system for visua...

Linear iteration coincides with multiplication by successive powers of a matrix; convergence of the iterates depends on the magnitude of its eigenvalues. We discuss in some detail a variety of convergence criteria based on the spectral radius, on matrix norms, and on eigenvalue estimates provided by the Gerschgorin Circle Theorem. We will then turn our attention to the three most important iter...

The primary concepts on which our spatial knowledge is based must have its origin in early individual development. One of these concepts is the notion of an object. Characteristic of the development of this concept is the so-called A-not-B-error (Piaget 1937). The error occurs in 6 to 8 months old infants that persist in reaching for location A, where an object was hidden several times, even th...

Motivation is a key ingredient for learning: If the learner is motivated, you may hope for some success. If she/he is not, you may as well stop here. Educational robotics has proven to be an excellent tool for motivating students at ages from 8 to 80. This paper describes the use of competitions in order to sustain motivation over a longer period of time, which increases the chances that the le...

According to the two-visual-system hypothesis (Milner and Goodale 1995), after V1 the visual system splits into vision-for-action and vision-for-perception modules. Specifically, the dorsal subsystem is proposed to specialize in the visual guidance of actions, whereas the ventral subsystem in object perception and recognition. Support for the two-visual-systems hypothesis has come from monkey a...

Modelling of thermo-mechanical processes in the metal industry has attracted much research interest over many years. As more and more insight is gained, there is a growing demand for through-process integrated thermo-mechanical process models to predict the microstructure evolution and the mechanical properties of the product during the whole production cycle. The main benefit of such an integr...

Short Abstract — Intergenic tandem repeats (TRs) containing transcription factor (TF) binding sites could serve as DNA decoys competitively binding TFs and affecting target gene expression. Using a yeast synthetic system, we demonstrate that repeated decoy sites tightly sequester a transcriptional activator and inhibit the promoter activation, creating a sigmoidal-like dose-response. This alter...

according to recent studies, about 60 percent of surface waters and 57 percent ground waters are located in snowy zones in iran. in most areas of northern hemisphere and alpine environment areas, snow melt lead to the maximum instantaneous flow rate and is an important part of annual discharge. the present study investigated the effect of snowmelt on the surface waters and ground waters in baha...
