background/objective: neonatal septicemia is one of the major causes of mortality in newborns. the aim of this study is to evaluate the clinical manifestations and laboratory findings in positive blood culture in neonatal septicemia. methods: in this retrospective study, we allocated 100 records positive blood culture of neonates suffering from septicemia. a questionnaire was completed for each...

in this paper, we propose and evaluate a novel design of a lightly doped drain and source carbon nanotube field effect transistor (ldds-cntfet) with a negative differential resistance (ndr) characteristic, called negative differential resistance ldds-cntfet (ndr-ldds-cntfet). the device was simulated by using a non equilibrium green’s function method. to achieve this phenomenon, we have created...

We discuss under what conditions Brownian transport processes can display negative resistance. We prove it cannot occur on 1D spaces like the circle or the line. We construct an entropic ratchet: an explicit two-dimensional model, and its collapse onto a branched 1D backbone, showing negative resistance and rectification as a consequence of a geometric symmetry breaking. We derive an accurate n...
