Glutathione is an important mediator and regulator of cellular redox processes. Detailed knowledge of local glutathione redox potential (E(GSH)) dynamics is critical to understand the network of redox processes and their influence on cellular function. Using dynamic oxidant recovery assays together with E(GSH)-specific fluorescent reporters, we investigate the glutathione pools of the cytosol, ...

IMS Learning Design (IMS LD) is a specification to realize adaptive and interoperable Units of Learning. However, the authoring process remains difficult, mainly due to the lack of high-level authoring IMS LD tools. In order to improve this process, more powerful external resources could be used. Furthermore, the main challenges are a) the authoring process, and b) the integration between these...

DNA sequences with the potential to form secondary structures such as i-motifs (iMs) and G-quadruplexes (G4s) are abundant in the promoters of several oncogenes and, in some instances, are known to regulate gene expression. Recently, iM-forming DNA strands have also been employed as functional units in nanodevices, ranging from drug delivery systems to nanocircuitry. To understand both the mech...

This paper is concerned with improving bandwidth utilization while guaranteeing qualityof-service (QoS) requirements for multimedia applications in IEEE 802.11e HCCA wireless networks. We propose two integer-multiple-spacing-based (IMS-based) designs: the IMSbased-d and IMS-based-l designs. In the IMS-based designs, the scheduling spacing of any traffic must be an integer multiple of the minimu...

In this paper we will explore security threats and attacks possibility and security solution for Application Server of IP Multimedia Subsystem(IMS-AS). The SIP Application Server is an important entity of IP Multimedia Subsystem (IMS) because applications providing value added services are deployed on the Application Server. The SIP Application Server is triggered by Serving Call State Control ...

The Information Manufacturing System (IMS) is the information system that manufactures information from raw data. Multi channel or multi source information system, cooperative information system and web information system work as the information manufacturing system of an organization. Data come from multiple sources are to execute refreshment and query function for making data available and in...

The 3rd Generation Partnership Project (3GPP) has proposed the IP Multimedia Subsystem (IMS) as a key element in the nextgeneration network (NGN) converged architecture supporting multimedia services. Extending the IMS towards provisioning support for location based services (LBS) will enable enhanced services and offer new revenues to the system. However, conveying location information in the ...

Due to the proteomics revolution, multi-dimensional separation and detection instruments are required to evaluate many peptides and proteins in single samples. In this study, electrospray ionization (ESI) ion mobility spectrometry (IMS) was evaluated as an additional separation after HPLC separations. Common HPLC mobile phase compositions (solvents, acid modifiers, and buffers) were assessed fo...

Advancing the field of physical activity (PA) monitoring requires the development of innovative multi-sensor measurement systems that are feasible in the free-living environment. The use of novel analytical techniques to combine and process these multiple sensor signals is equally important. This paper describes a novel multi-sensor 'integrated PA measurement system' (IMS), the lab-based method...

1 The IP multimedia Subsystem (IMS) is a network functional architecture that is seen as a promising solution for facilitating multimedia service creation and deployment, as well as supporting interoperability and network convergence. IMS allows network operators to play a central role in traffic distribution, therefore being more than “bit pipes”. For all these reasons, IMS has generated inten...
