In this paper, we study a coalitional game approach to resource allocation in a multi-channel cooperative cognitive radio network with multiple primary users (PUs) and secondary users (SUs). We propose to form the grand coalition by grouping all PUs and SUs in a set, where each PU can lease its spectrum to all SUs in a time-division manner while the SUs in return assist PUs’ data transmission a...
Sulfonylureas (SUs) have been available for the treatment of type 2 diabetes mellitus (T2DM) patients since 1950s and still occupy a central position in all international guidelines for diabetes management. With improved understanding of pathophysiology of T2DM and introduction of a number of newer oral agents, there is need to critically re-evaluate the effectiveness and safety of SUs, to asse...
In cognitive radio networks, there are scenarios where secondary users (SUs) utilize opportunistically the spectrum originally allocated to primary users (PUs). The spectrum resources available to SUs fluctuates over time due to PUs activity, SUs mobility and competition between SUs. In order to utilize these resources efficiently spectrum sharing techniques need to be implemented. In this pape...
The financing of SUS in a scenario of financialization O financiamento do SUS sob os " ventos " da financeirização Resumo O artigo reconstitui o processo de institu-cionalização do financiamento do SUS, prejudica-do, em primeira instância, pelas condições da polí-tica macroeconômica desenvolvida ao longo dos anos 1990 e 2000, e, em última instância, pelos efeitos provocados pela atual fase do c...
Amyloid-β (Aβ) peptide has been implicated in the pathogenesis of Alzheimer's disease (AD). We present a nonpharmacological approach for removing Aβ and restoring memory function in a mouse model of AD in which Aβ is deposited in the brain. We used repeated scanning ultrasound (SUS) treatments of the mouse brain to remove Aβ, without the need for any additional therapeutic agent such as anti-Aβ...
In this paper, the problem of power control for cognitive systems is studied via game theory. The objective is to maximize the sum utility of secondary users (SUs) subject to the primary users (PUs) interference constraints, the transmission power constraints of SUs, and the signal-to-interference-plus-noise ratio (SINR) constraint of each SU. In our earlier work, the problem was formulated as ...
The need to acquire intellectual capital created the Knowledge Management (KM) movement, which aims to develop new practices and tools to capture knowledge. Indepth examination of current KM projects revealed the largest percent of KM projects attempting to create some kind of a knowledge repository. Current studies identify three types of knowledge repositories. One type of knowledge repositor...
We propose a distributed spectrum access algorithm for cognitive radio relay networks with multiple primary users (PUs) and multiple secondary users (SUs). The key idea behind the proposed algorithm is that the PUs negotiate with the SUs on both the amount of monetary compensation, and the amount of time the SUs are either (i) allowed spectrum access, or (ii) cooperatively relaying the PU’s dat...
Since their introduction in clinical practice in the 1950's, Sulfonylureas (SUs) have remained the main-stay of pharmacotherapy in the management of type 2 diabetes. Despite their well-established benefits, their place in therapy is inappropriately being overshadowed by newer therapies. Many of the clinical issues associated with the use of SUs are agent-specific, and do not pertain to the clas...
We have developed a mathematical model of the human atria myocyte based on averaged voltage-clamp data recorded from isolated single myocytes. Our model consists of a Hodgkin-Huxley-type equivalent circuit for the sarcolemma, coupled with a fluid compartment model, which accounts for changes in ionic concentrations in the cytoplasm as well as in the sarcoplasmic reticulum. This formulation can ...
