To prove feasibility of proton chemical shift imaging ((1)H CSI) during stereotactic procedure, authors performed (1)H CSI in combination with a stereotactic headframe and selected targets according to local metabolic information, evaluated the pathologic results. The (1)H CSI directed stereotactic biopsy was performed in four patients. (1)H CSI and conventional Gd-enhancement stereotactic MRI ...

Objective: The Cerebral State index (CSI) is a new index based on electroencephalogram to monitor depth of anesthesia. Transferring guidelines for titration of the Bispectral index (BIS) to the CSI depends on their compatibility. We compared the relationship between BIS and CSI values during propofol-remifentanil anesthesia. Methods: Forty one adult patients about to have open heart surgeries w...

Cesium iodide (CsI) melt was injected into anodic aluminum oxide (AAO) template and was solidified to CsI column. The controllable AAO channel size (10~500 nm) can makes CsI column size from 10 to 500 nm in diameter. In order to have a shorter light irradiate from each singe CsI column top to bottom the AAO template was coated a TiO2 nano-film. The TiO2 film acts a refraction film and makes X-r...

The degrees of freedom (DoF) region of the two-user MIMO interference channel (IC) is completely characterized in the presence of noiseless channel output feedback from each receiver to its respective transmitter and with the assumption of delayed channel state information (CSI) at the transmitters. It is shown that having output feedback and delayed CSI at the transmitters can strictly enlarge...

In information theoretic analysis of communication over MIMO broadcast channels, two extreme assumptions about availability of the channel state information (CSI) at the base station are usually made; either perfect CSI is available at the transmitter, or no CSI is available at all. However, in practical systems, there is usually CSI feedback but the feedback is subject to delays. Conventionall...

OBJECTIVE To compare the value of Glasgow coma scale (GCS) and cerebral state index (CSI) on predicting hospital discharge status of acute brain-injured patients. METHODS In 60 brain-injured patients who did not receive sedatives, GCS and CSI were measured daily during the first 10 days of hospitalization. The outcome of prognostic cut-off points was calculated by GCS and CSI using receiver o...

We consider the cognitive power control problem of maximizing the secondary throughput under an outage probability constraint on a constant-power constant-rate primary link. We assume a temporally correlated primary channel with two types of feedback: perfect delayed channel state information (CSI) and one-bit automatic repeat request (ARQ). We use channel correlation to enhance the primary and...

To detect spatially-modulated signals, a receiver needs the channel state information (CSI) about each transmit-receive antenna pair. Although the CSI (or channel response information) is never perfect and varies in time, most studies on spatial modulation (SM) systems assume perfectly known CSI and time-invariant channel. The spatial correlations among multiple spatial subchannels, which have ...

Link adaptation in LTE-A is based on channel state information (CSI). For time-selective channels, CSI might be outdated already in the next subframe. Hence, CSI prediction must be employed. This paper investigates support vector regression (SVR) for channel extrapolation and prediction. SVR is applied for learning from the previous channel estimates in order to predict the CSI of the following...

background variables derived from electroencephalogram like cerebral state index (csi) have been used to monitor the anesthesia depth during general anesthesia. observed evidences show such variables have also been used as a detector of brain death or outcome predictor in traumatic brain-injured (tbi) patients. objectives the current study was designed to determine the correlation between glasg...
