Using improved selection techniques, we isolated four monoclonal antibodies with high affinity for human thyrotropin (Ka = 1.6 X 10(8) to 2.6 X 10(10) L/mol). We used two of these in an immunoradiometric assay (IRMA) that also incorporates a novel phase-separation technology (Sucrosep TSH IRMA, Boots-Celltech). This assay's very low detection limit for TSH (0.03-0.08 milli-int. unit/L) and wide...

This paper presents an integrated routing and MAC scheduling algorithm (IRMA) for improving system performance in multihop wireless mesh networks. The IRMA approach is motivated by the fact that conventional contention-based MAC protocols such as 802.11 do not perform well in combination with independent ad hoc routing protocols such as DSR, DSDV or AODV due to interactions between neighboring ...

Intra-organizational networks (intranets) are increasingly being developed for information sharing and collaborative work in geographically dispersed organizations. In this paper we provide a framework to manage the resources in the intranets using the concepts of electronic commerce. Specifically, we propose the creation of an intranet Resource Management Application (iRMA) which manages the u...

Drawing on the boundary theory (Nippert-Eng, 1996a) and the concept of institutional framework according to Piszczek and Berg (2014), we explore in this paper the link between institutional settings and boundary management practices in the case of selfemployed German lawyers. Qualitative empirical results on the basis of 12 interviews reveal that the institutional context in case of self-employ...

Modern communication standards such as Digital Imaging and Communication in Medicine (DICOM) include nonimage data for a standardized description of study, patient, or technical parameters. However, these tags are rather roughly structured, ambiguous, and often optional. In this paper, we present a mono-hierarchical multi-axial classification code for medical images and emphasize its advantages...

Transmitting digital information using ultra-short pulses, Impulse Radio (IR) has received increasing interest for Multiple Access (MA). Analog IRMA utilizes pulse-position modulation (PPM) and random time-hopping codes to mitigate inter-symbol interference (ISI) and suppress multiuser interference (MUI) statistically. We develop an alldigital IRMA scheme that relies on block-spreading and judi...

In this paper, we describe an approach for the automatic medical annotation task of the 2008 CLEF cross-language image retrieval campaign (ImageCLEF). The data comprise 12076 fully annotated images according to the IRMA code. This work is focused on the process of feature extraction from images and hierarchical multi-label classification. To extract features from the images we used a technique ...
