objective(s)bioelectrical impedance is the measure of impedance of the body. impedance consists of electric resistance and reactance. phase angle (pa) is the tan value of the ratio of reactance versus electric resistance. pa depends on cell membrane integrity and on body cell mass. there exists a correlation between pa values and body cell mass.the objective of this study was to compare the pa ...

introduction: in the present study, we hypothesized that a novel approach to promote vascularization would be to create injectable three dimensional (3-d) scaffolds within growth factor that enhance the sustained release of growth factor and induce the angiogenesis. material and methods: we demonstrate that a 3-d scaffold can be formed by mixing of peptide-amphiphile (pa) aqueous solution with ...

objective: to evaluate the efficacy and safety of intravenous and catheter directed thrombolysis by recombinant tissue plasminogen activator (alteplase) in the patients with non-traumatic acute limb ischemia (ali). methods: this was a randomized clinical trial being performed between 2009 and 2011 in mashhad university of medical sciences. we included those patients who were<75 years, with symp...

A degree is saturated bounding if it can compute a saturated model for any complete, decidable theory whose types are all computable. All high and PA degrees are saturated bounding (following from results of Jockusch and MacIntyre-Marker.) We show that for every n, no lown c.e. degree is saturated bounding, extending the previous known result that 0 is not saturated bounding, by Millar.

We consider Personal Assistant (PA) agents as cognitive agents capable of helping users handle tasks at their workplace. A PA must communicate with the user using casual language, sub-contract the requested tasks, and present the results in a timely fashion. This leads to fairly complex cognitive agents. However, in addition, such an agent should learn from previous tasks or exchanges, which wi...
