Regional cerebral blood flow (rCBF) asymmetries were studied in controls and patients with common and classic/complicated migraine using Xe inhalation with 8 homologously situated external collimators over each cerebral hemisphere. Migraine patients as a group more frequently had posterior rCBF asymmetries than controls (p<0.03). Although there were no differences in the number of anterior rCBF...

This paper describes a mechanism for utilizing Inverse Multiplexing to significantly increase the bandwidth available to short-range wireless devices. Previous work with Inverse Multiplexing has focused on wired networks; its implementation with short-range wireless transports introduces heterogeneity in the links, which must be taken into account. A mathematical model for an Inverse Multiplexi...

INFARCTION IN THE VERTEBRO-BASILAR artery distribution has been noted in a variety of circumstances associated with head turning and hyperextension of the neck, but the interval between the trauma and the cerebrovascular stroke is usually short. This paper describes a patient who developed a cerebellar infarction five weeks following a car accident, an unusually long delay which deserves mentio...

This study extends the literature of dynamic advertising competition by allowing oligopoly competition and market expansion that results from advertising. We "nd how advertising actions a!ect market development and how, conversely, market development in#uences advertising policies over time. Modelling the competition by a di!erential game, we solve for both time-variant closed-loop and time-inv...

Hypoglycemic hemiplegia mimics cerebrovascular disease. Two patients are reported who experienced multiple attacks of transient hemiplegia associated with hypoglycemia and who were initially diagnosed as having transient ischemic attacks. In both, angiography was normal and the attacks resolved with reduction of insulin dose. Recognition of hypoglycemia as the cause of transient hemiplegia is i...

This work introduces, for the first time, nonorthogonal multiple access (NOMA) into short-packet communications to achieve low latency in wireless networks. Specifically, we address the optimization of transmission rates and power allocation to maximize the effective throughput of the user with a higher channel gain while guaranteeing the other user achieving a certain level of effective throug...

this is a survey of some recent applications of abstract algebra, and in particular group rings, to the `communications' areas.

In recent years, artificial intelligence (AI) aided communications grabbed huge attention to providing solutions for mathematical problems in wireless communications, by using machine learning (ML) and deep (DL) algorithms. This paper initially presents a short background on AI, CEM, the role of AI / ML DL antennas. A study algorithms optimization techniques antenna parameters various are prese...
