The vertical circuitry controls the vertical axis of the display and consists of an input coupling circuit, the input attenuator, and the vertical amplifier (for dual trace oscilloscopes, there are two identical vertical circuits, one for each channel). All signals connected to the vertical input jacks are fed through at least part of the vertical circuitry before they are used by other oscillo...

A unidirectional ensemble of hemicyanine molecules was prepared by inserting the molecules into the vertical channels of a uniformly oriented zeolite (silicalite-1) film grown on a glass substrate. Fluorescence from this sample excited with light polarized along the vertical channel was 50 times larger than that excited with light polarized orthogonal to the vertical channel direction. These ve...

An orthogonal decomposition of a general wideband space-time multipath channel is derived assuming antenna arrays at both the transmitter and receiver. This decomposition provides a framework for efficiently managing the available space-time channel dimensions using channel state information at the transmitter and receiver. Signaling and receiver designs for high throughput applications are der...

Identifying the properties of correlations in the firing of neocortical neurons is central to our understanding of cortical information processing. It has been generally assumed, by virtue of the columnar organization of the neocortex, that the firing of neurons residing in a certain vertical domain is highly correlated. On the other hand, firing correlations between neurons steeply decline wit...

Vertical handover, which often occurs in wireless mobile communication, is very important for heterogeneous wireless networks based on the cognitive radio (CR). However, a major issue is how to control vertical handover for secondary user without interfering primary user while achieving the desired quality of service (QoS) and eliminating the influence caused by hidden channel and exposed chann...
