The NGN (Next Generation Network), which can provide advanced multimedia services over an all-IP based network, has been the subject of much attention for years. While there have been tremendous efforts to develop its architecture and protocols, especially for IMS, which is a key technology of the NGN, it is far from being widely deployed. However, efforts to create an advanced signaling infras...

© 1997 John Wiley & Sons, Inc. The objective of this review is to provide an overview of the capabilities and limitations of ion mobility spectrometry (IMS) as it pertains to field screening. The first section of the review provides a description of the instrument and its operation along with examples of its primary advantages of simplicity, selectivity, and sensitivity. IMS is a simple and pot...

In this work we evaluate the influence of thermal desorber temperature on the analytical response of a swipe-based thermal desorption ion mobility spectrometer (IMS) for detection of trace explosives. IMS response for several common high explosives ranging from 0.1 ng to 100 ng was measured over a thermal desorber temperature range from 60 °C to 280 °C. Most of the explosives examined demonstra...

Ion mobility spectrometry (IMS) coupled to orthogonal time-of-flight mass spectrometry (TOF) has shown significant promise for the characterization of complex biological mixtures. The enormous complexity of biological samples (e.g., from proteomics) and the need for both biological and technical analysis replicates imposes major challenges for multidimensional separation platforms with regard t...

The mitochondrial intermembrane space (IMS) harbors an oxidizing machinery that drives import and folding of small cysteine-containing proteins without targeting signals. The main component of this pathway is the oxidoreductase Mia40, which introduces disulfides into its substrates. We recently showed that the IMS glutathione pool is maintained as reducing as that of the cytosol. It thus remain...

In this study, daily maps of snow cover distribution and sea ice extent produced by NOAA’s interactive multisensor snow and ice mapping system (IMS) were validated using in situ snow depth data from observing stations obtained from NOAA’s National Climatic Data Center (NCDC) for calendar years 2006 to 2010. IMS provides daily maps of snow and sea ice extent within the Northern Hemisphere using ...

OBJECTIVE To develop a conceptual framework for the design of an in-home monitoring system (IMS) based on the requirements of older adults with vision impairment (VI), informal caregivers and eye-care rehabilitation professionals. MATERIALS AND METHODS Concept mapping, a mixed-methods statistical research tool, was used in the construction of the framework. Overall, 40 participants brainstorm...

Linus Pauling Institute, Oregon State University, Corvallis, OR 97331, USA Abstract The use of ion-mobility spectrometry (IMS) coupled to mass spectrometry (IMS–MS) for biomolecule analyses has steadily increased over the past two decades, and is now applied to both proteomic and metabolomic investigations. This chapter describes the application of traveling-wave ion-mobility spectrometry–mass ...

BACKGROUND AND OBJECTIVES The significant rise in food borne infections is mainly caused by Campylobacter spp., Salmonella serovars and Verotoxigenic Escherichia coli. As the emerging food borne pathogens cause disease, more studies have been conducted for rapid detection of these pathogens. The combination of immunomagnetic separation and polymerase chain reaction (IMS-PCR) is the most accurat...

This study aims to further the understanding of how innovative moments (IMs), which are exceptions to a client's problematic self-narrative in the therapy dialogue, progress to the construction of a new self-narrative, leading to successful psychotherapy. The authors' research strategy involved tracking IMs, and the themes expressed therein (or protonarratives), and analysing the dynamic relati...
