This work highlights the rapid detection of nitrate ester explosives and their sugar alcohol precursors by direct analysis in real time mass spectrometry (DART-MS) using an off-axis geometry. Demonstration of the effect of various parameters, such as ion polarity and in-source collision induced dissociation (CID) on the detection of these compounds is presented. Sensitivity of sugar alcohols an...

background: this study was to determine the sensitivity, specificity, positive predictive value (ppv), negative predictive values (npv) and agreement between two methods of the stained gastric imprint cytology smears and stained gastric specimen biopsy mucosal methods for detection of h. pylori. methods: air-dried imprint smears of gastric biopsies from 330 patients were stained by the grunwald...

In birds, there is a retinofugal projection from the brain to the retina originating from the isthmo optic nucleus (ION) in the midbrain. Despite a large number of anatomical, physiological and histochemical studies, the function of this retinofugal system remains unclear. Several functions have been proposed including: gaze stabilization, pecking behavior, dark adaptation, shifting attention, ...

The ion-step method was originally designed to measure immunoreactions via the change in charge density which occurs in an antibody loaded membrane, deposited on an ISFET, upon reaction with a charged antigen. In this paper we show the possibility of detecting an immunoreaction involving a non-charged antigen, progesterone, by using competitive binding of progesterone and a charged progesterone...

ion-Based Intrusion Detection The implementation of many misuse detection approaches shares a common problem: Each system is written for a single environment and has proved difficult to use in other environments that may have similar policies and concerns. The primary goal of abstraction-based intrusion detection is to address this problem.

Background: Erythropoietin, as a principal hormone promotes red blood cell production in bone marrow. Varieties of erythropoietin biosimilar are being produced by recombinant DNA technology in cell cultures. The detection or quantification of these molecules are being performed by diff erent methods which some of theme such as Western blot and enzymelinked immunosorbent assay (ELISA) require sp...

This dissertation reports on the demonstration of a mechanical analogue to an optical laser, a ”phonon laser”, using a single trapped ion. Furthermore, we show that the dynamics of this system are surprisingly sensitive to external fields; we demonstrate phase synchronization (”injection locking”) to an external signal by applying forces as weak as 5 yN (yocto=10). This enormous sensitivity mig...
