We have designed a novel system called a Secure Integrity Measurement System (SIMS) to provide a practical integrity for flexible and traditional remote systems. SIMS is not only targeted for Linux, but it can also be used for different operating systems such as Windows, and UNIX. All and executable content that are loaded onto any operating system is measured before execution. These measuremen...

A novel, trehalose-glycerol matrix was utilized to generate high-resolution, TOF-SIMS images of macrophages and glial cells. Viable cells incubated in 50 mM trehalose, then lyophilized in a 50 mM trehalose, 10-15% (w/w) glycerol rinse, are preserved and chemically profiled. These experiments demonstrate the utility of the disaccharide matrix as an efficient, cost-effective alternative to cryoge...

This paper investigates how the thermal diffusion of boron in silicon is influenced by a high energy fluorine implant with a dose in the range 531014–2.331015 cm−2. Secondary Ion Mass Spectroscopy (SIMS) profiles of boron marker layers are presented for different fluorine doses and compared with fluorine profiles to establish the conditions under which thermal boron diffusion is suppressed. The...

This study explores physical effects associated with the application of cryopreservation via vitrification using a class of compounds which are defined here as synthetic ice modulators (SIMs). The general classification of SIMs includes molecules that modulate ice nucleation and growth, or possess properties of stabilizing the amorphous state, by virtue of their chemical structure and at concen...

OBJECTIVE The aim of this study was to develop and pilot an instrument for the assessment of self-injury in adolescent inpatients. METHODS The Self-Injury Motivation Scale was modified for use in adolescents. Thirty-eight consenting adolescent inpatients with a history of self-injury completed the Self-Injury Motivation Scale-Adolescent version (SIMS-A) and the Self-Injury Interview (SII) to ...

Our research focuses on developing System Importance Measures (SIMs) to characterize resilience. Our measures are applicable to systems and systems-of-systems that are characterized by diversity in nodes and functions. The system importance measures help identify and rank components or systems that have the most impact on different aspects of the overall resilience. Because systems-of-systems (...

Understanding the influence of molecular environment on phospholipids is important in time-of-flight secondary ion mass spectrometry (TOF-SIMS) studies of complex systems such as cellular membranes. Varying the molecular environment of model membrane Langmuir-Blodgett (LB) films is shown to affect the TOF-SIMS signal of the phospholipids in the films. The molecular environment of a LB film of d...

In this study, we show that the rate of shell precipitation in the extant planktic foraminifer Orbulina universa is sufficiently rapid that 12 h calcification periods in O-labeled seawater can be resolved and accurately measured using secondary ion mass spectrometry (SIMS) for in situ dO analyses. Calcifying O. universa held at constant temperature (22 C) were transferred every 12 h between amb...

Analyses by secondary ion mass spectroscopy (SIMS) of 11 specimens of five taxa of prokaryotic filamentous kerogenous cellular microfossils permineralized in a petrographic thin section of the ∼3,465 Ma Apex chert of northwestern Western Australia, prepared from the same rock sample from which this earliest known assemblage of cellular fossils was described more than two decades ago, show their...
