Ion mobility spectrometry-time-of-flight mass spectrometry (IMS-TOFMS) has been increasingly used in analysis of complex biological samples. A major challenge is to transform IMS-TOFMS to a high-sensitivity, high-throughput platform, for example, for proteomics applications. In this work, we have developed and integrated three advanced technologies, including efficient ion accumulation in an io...

Imaging mass spectrometry (IMS) has become a prime tool for studying the distribution of biomolecules in tissue. Although IMS data sets can become very large, computational methods have made it practically feasible to search these experiments for relevant findings. However, these methods lack access to an important source of information that many human interpretations rely upon: anatomical insi...

BACKGROUND The study aim was to determine the kinetics of serum pro- and anti-inflammatory cytokines and C-reactive protein (CRP) in hip-fracture patients over a month postfracture, and their relationship to postoperative (postop) complications and cognitive level. METHODS Forty-one elderly hip-fracture patients were prospectively followed. Serum was obtained during the first 10 hours postfra...

Odorous emissions from wastewater treatment plants (WWTPs) cause negative impacts on the surrounding areas and possible health risks nearby residents. However, efficient reliable identification of WWTPs’ odorants is still challenging. In this study, odorous volatile organic compounds (VOCs) domestic at different processing units were profiled identified using gas chromatography-ion mobility spe...

With IMS and WebRTC being both recognized as key technologies for communication services and as technological investments are ongoing there is a need to understand what each technology can do that the other cannot. This paper provides an extensive analysis allowing for a side by side comparison of IMS and WebRTC taking into account the respective standards but also how the technologies are impl...

The IP Multimedia Subsystem (IMS) infrastructure is currently considered to be the main core of Next Generation Networks (NGNs), integrating IP and other network types under one common infrastructure. Consequently, IMS inherits security flaws and vulnerabilities residing in all those technologies. Besides, the protection against unauthorized access in NGN services is of great importance. In thi...

One of the most critical tasks when accessing services through the IP Multimedia Subsystem is the registration process. The process involves two registrations, the first with the access network, the second with IMS. This leads to an overhead authentication that introduces a big delay. This article proposes an improvement for IMS registration protocol able to relate IMS registration to an access...
