When a speaker talks, the consequences of this can be heard (audio) and seen (visual). We use a novel visual phonemic restoration task to assess behavioral discrimination and neural signatures (ERP) of audiovisual processing in typically developing children with a range of social and communicative skill and in children with autism. In an auditory oddball design we presented two types of stimuli...

We present the development of a four-channel low-cost hardware system for data acquisition, with application in dedicated nuclear medicine imagers. A 12 bit octal channel high-speed analogue to digital converter, with up to 65 Msps sampling rate, was used for the digitization of analogue signals. The digitized data are fed into a field programmable gate array (FPGA), which contains an interface...

Topological spin textures can serve as non-volatile information carriers. Here we study the current-induced dynamics of an isolated magnetic skyrmion on a nanoscale square-grid pinning pattern formed by orthogonal defect lines with reduced anisotropy. The square grid be pixelated quantized size grid. We demonstrate that position, size, and shape are electrically configurable. center is to may s...

We introduce a novel video-rate hyperspectral imager with high spatial, temporal and spectral resolutions. Our key hypothesis is that profiles of pixels within each super-pixel tend to be similar. Hence, scene-adaptive spatial sampling scene, guided by its segmented image, capable obtaining high-quality reconstructions. To achieve this, we acquire an RGB image the compute super-pixels, from whi...

introduction: image quality and accuracy of in vivo activity quantification in spect are affected by collimator penetration and scatter components, especially in high energy imaging. these phenomena highly depend on the collimator characteristic and photon energy. the presence of penetrated and scattered photons from collimator in spect images degrades spatial resolution, contrast and image qua...

Optical lithography has enabled the printing of progressively smaller circuit patterns over the years. However, as the feature size shrinks, the lithographic process variation becomes more pronounced. Source-mask optimization (SMO) is a current technology allowing a co-design of the source and the mask for higher resolution imaging. In this paper, we develop a pixelated SMO using inverse imagin...

In the two space dimensions of screens in optical systems, rotations, gyrations, and fractional Fourier transformations form the Fourier subgroup of the symplectic group of linear canonical transformations: U(2)F⊂Sp(4,R). Here, we study the action of this Fourier group on pixelated images within generic rectangular Nx×Ny screens; its elements here compose properly and act unitarily, i.e., witho...
