In this issue of Neuron, Fried et al. report electrical recordings from single neurons in several areas of the human medial frontal lobe prior to voluntary movement. These data shed important new light on the neuronal mechanisms of human volition and on the hotly debated relation between consciousness and will.

We report a two-photon interference experiment that realizes a postselection-free test of Bell’s inequality based on energy-time entanglement. In contrast with all previous experiments of this type, the employed entangled states are obtained without the use of a beam splitter or a short coincidence window to ‘‘throw away’’ unwanted amplitudes. A ~95.061.4!% interference fringe visibility is obs...

A cost-effective method for cloud removal and reconstruction of remote sensing images has been a long-standing research challenge in data processing. In this paper, we address by presenting fast simple detection cloud-free image using Landsat-8 OLI Sentinel-2 MSI series data. The proposed utilizes the spectral difference between pixels transparent to develop algorithm multispectral sensors. Sub...
