introduction :  despite  recent  advances  in  treatment  of  oral  cancer,  it  still causes high rates of mortality and morbidity worldwide. delays in diagnosis and treatment of these cancers greatly affect the prognosis.  this study aimed to assess the treatment delay and its relation to diagnostic delay among oral cancer patients in tehran, iran. materials and methods : we studied 100 patie...

In this letter, a new addressing scheme for hexagonal networks is proposed. Using the new addressing scheme, many routing algorithms designed for networks using square-based topologies such as mesh and torus can also be applied to hexagonal networks. Methods of applying the turn model to hexagonal networks are derived, with some new minimal and partial adaptive routing algorithms obtained. Simu...

background treatment of patients with acute myocardial infarction (ami) is time related, so delay in treatment could affect prognosis. recognizing pre-hospital or in-hospital delays in initiating treatment and reducing these factors is very efficacious in treatment of these patients. results 35.7% patients arrived during one hour of symptom onset, and 7.9% arrived after 24 hours. patients havin...

In this paper, a new T-S fuzzy hyperbolic delay model for a class of nonlinear systems with time-varying delay, is presented to address the problems of stability analysis and feedback control. Fuzzy controller is designed based on the parallel distributed compensation (PDC), and with a new Lyapunov function, delay dependent asymptotic stability conditions of the closed-loop system are derived v...

New anhydrous alkali lanthanide-free polyoxometalates have been elaborated by thermal decomposition of their parent hydrates, and they exhibit remarkable reversible turn-off-on luminescence properties at room temperature in the presence humidity.

Recently two ways of concatenating pushdowns have be investigated and it has been argued that the resulting storage types might be useful for the description of natural languages. In this paper I will consider concatenations of oneeturn pushdowns. I will give characterizations of the languages accepted by automata using these storage types in terms of linear grammars with controlled derivations...

In this work, it has been demonstrated through experiments that Long Range Dependence (LRD) in internet traffic is indeed affecting the queueing performance. Queueing performance is being degraded as the self-similarity of the packet arrival process increases. Here, the link buffer capacity and queueing delay exhibits super-linear relationship. This in turn has led to the proposal of resource p...
