In this paper we analyze the effects of body shadowing in multiple-input-multiple-output (MIMO) channels used for personal area networks (PANs). We give physical reasoning to why PANs may experience two different types of shadowing, and to support our argument, we present results from a measurement campaign for three different PAN channels with human influence. The campaign is performed using diff

This work introduces a novel analytical method for the detection and study of GAD65 autoantibodies, which have been implicated in the onset of type 1 diabetes. There is a clinical need for a rapid and automated assay for GAD65 autoantibodies. Therefore, this method was designed to exploit the advantages of bead injection (BI) analysis for enzyme-linked immunosorbent assays (ELISA). BI ELISA is a m

Neutron deficient nuclei near Sn-100 have been produced by fragmentation of a 1 (.) A GeV Sn-112 beam. The fragments were separated, identified and stopped in a highly segmented silicon strip detector stack. This detector measured the total energy of emitted beta(+)-particles. gamma-radiation was measured with surrounding detectors. The half-lives for many nuclides have been determined for the fir

Antibacterial activity of 17 strains of lactobacilli was tested against 10 strains of H. pylori. The inhibition observed was related to the acid production and the low pH attained. No relationship between CagA phenotype of H, pylori strains and tolerance to lactic acid was observed. In mixed cultures, L. acidophilus CRL 639 showed an autolytic behavior after 24 h of culture. At this moment, H. py[

In the 1940s, Swedish poetry saw the breakthrough of modernism. With the modernist style came a new kind of poetic aspiration towards the condition of music: semantic imitations of musical genres and attempts to create, with the help of the words' associations, an aesthetic effect similar to a musical effect. This type of intermediality, which I call semantic musicality, was inherited as a norm of

Planar lung scintigraphy is a standard method used for the diagnosis of lung embolism, but it is hampered by the high incidence of nondiagnostic tests. Ventilation/perfusion SPECT may possibly improve this situation. The objective of this study was to compare planar lung scintigraphy with ventilation/perfusion SPECT using pigs with artificially engendered lung emboli labeled with (201)Tl. METHODS:

Osteoadherin (OSAD) is a keratan sulfate proteoglycan recently isolated from bovine and rat bone. Based on results obtained from in vitro experiments, the protein was shown to bind osteoblasts via the integrin receptor alpha(v)beta(3). Due to OSAD's capacity to bind hydroxyapatite crystals, a role for the protein in the mineralization process has also been suggested. To test these hypotheses in an

In this letter, we demonstrate the realization of novel diodes, triodes, and logic gates with three-terminal ballistic junctions (TBJs) made from a semiconductor heterostructure. The approach exploits the ballistic nature of electron transport, which has emerged in the nanostructures. Importantly, we show that TBJs function as logic AND gates and can be used to construct other compound logic gates

A flow injection analysis (FIA) system for specific determination of L-glutamate in food samples based on a bi-enzymatic amplification system has been developed. The content of L-glutamate in the sample was amplified by cycling between L-glutamate dehydrogenase (GIDH) and a novel enzyme, D-phenylglycine aminotransferase (D-PhgAT). In this system, GIDH converts L-glutamate to 2-oxoglutarate with co

Seven patients with type 1 diabetes mellitus were restored to near normoglycaemia by treatment with continuous subcutaneous insulin infusion pumps (CSII). The patients were examined with ophthalmoscopy, fundus photography and fluorescein angiography before and one year after the start of CSII treatment. In addition, ophthalmoscopy was performed after 6 months of treatment. All 14 eyes were normal

Bi-isonicotinic acid (2,2'-bipyridine-4,4'-dicarboxylic acid) is an important ligand in the chemistry of organometallic devices. Here, the adsorption of a monolayer of the molecule on in situ-grown anatase TiO2 nanoparticles has been investigated by means of X-ray photoemission spectroscopy and X-ray absorption spectroscopy. The bonding geometry is determined to be 2M-bidentate. Furthermore, reson

The purpose of this study was to determine the reliability of an isokinetic test for ankle dorsiflexion fatigue on a Biodex dynamometer Young (21 to 32 years), recreationally active men (n = 10) and women (n = 10) performed 50 concentric (60degrees . s(-1)) dorsiflexion contractions, on two different occasions. Total work (TW), losses in work (work fatigue; WF), as well as relative losses in peak

Objective: To review and sum up the published literature on gynecological Doppler ultrasound examination. Methods: Publications on gynecological Doppler ultrasound examination already known by the author, publications found in the bibliographic database Medline, and publications found in the reference lists of available studies were read, and relevant information was extracted and summarized.
