Multiple Beam Selection for Combing M2M Communication Networks and Cellular Networks with Limited Feedback
Published 2013-12-01“…We consider an overlay mode of an orthogonal frequency division multiple access (OFDMA) based cellular system using orthogonal beamforming to provide broadband wireless access for the MTCD gateways. In order to avoid the interference with mobile users, the beamforming vectors to the MTCD gateways have to be orthogonal to the channel vectors of mobile users, which become a beamforming constraint for the MTCD gateways. …”

Neurocranial Pharmacodialysis Device for subarachnoid hemorrhage treatment—a perspective
Published 2024-02-01“…The RESULTS showed the following four facts: (1) high-grade SAH requiring decompressive craniectomy readily offers, as the last step of the neurosurgical procedure, the safe closure of the opened cranium with the NPD while leaving the efficacy of the decompressive intervention intact. (2) The neurocranially attached NPD can automatically execute, as long as it is necessary, subarachnoid polypharmacy to prevent post-SAH vasospasm, reduce the risk of rebleeding, and provide neuroprotection in delayed cerebral ischemia (DCI), bypassing the blood-brain barrier (BBB) via connected subarachnoid strips. (3) These effects of drug delivery can be optimized with NPD-controlled long-term cleaning of the CSF and drainage of cellular debris, hydrocephalus, and interstitial edema accompanied by the subarachnoid dialysis of potentially neurotoxic extracellular molecules. (4) Safety and efficacy of these NPD operations are monitored, and possible epileptiform EEG is detected, via the wireless EEG system of the device. The CONCLUSION was that complementing conservative therapies with NPD implantation can reduce the current substantial mortality and morbidity among hospitalized survivors of SAH.…”
