We consider a cooperative wireless network where a set of nodes cooperate to relay in parallel the information from a source to a destination using a decode-and-forward approach. The source broadcasts the data to the relays, some or all of which cooperatively beamform to forward the data to the destination. We generalize the standard approaches for cooperative communications in two key respects: (

Asymptomatic bacteriuria (ABU) is a common clinical condition that often leads to unnecessary antimicrobial use. The reduction of antibiotic overuse for ABU is consequently an important issue for antimicrobial stewardship and to reduce the emergence of multidrug resistant strains. There are two issues in everyday urological practice that require special attention: the role of ABU in pre-operative

To evaluate measurement properties of 2 brief outcome measures for carpal tunnel syndrome: the 6-item carpal tunnel symptoms scale (CTS-6) and the 2-item palmar pain scale (measuring severity of pain in the scar/palm and pain-related activity limitation). Our hypothesis was that the CTS-6 is responsive to change in symptoms after surgical treatment and the pain scale is a valid measure of surgery-

A polyacrylamide gel crosslinked with allyl-b-cyclodextrin can be used repeatedly for several weeks for the separation of DNA fragments, since bubbles are not generated during a run. Allyl-b-cyclodextrin can easily be synthesized in one step from allylglycidylether and b-cyclodextrin. The plate numbers for DNA fragments, up to about 1500 bp, are high: for the 21 separation of pBR322/HaeIII fragmen

Analysis of prospectively collected data in a national register.

PURPOSE: To evaluate the use of x-ray imaging performed with a high-power laser system in biologic and medical studies. MATERIALS AND METHODS: A compact terawatt laser system based on chirped pulse amplification in titanium-doped sapphire was used. X rays were generated by irradiating a high-atomic-number target (tantalum). RESULTS: When photons with an energy below 10 keV were removed with use of

Background Studies in many countries have reported higher lung cancer incidence and mortality in individuals with lower socioeconomic status. Methods To investigate the role of smoking in these inequalities, we used data from 391 251 participants in the European Prospective Investigation into Cancer and Nutrition study, a cohort of individuals in 10 European countries. We collected information on

This is an exploratory study investigating potential effects of emotional valence in images and their influence on conversation in the presence of the images. We used latent-semantic analysis to generalize valence ratings of Swedish words to a corpus of spoken conversations. Each utterance in the conversation was given a valence rating, which represented how emotionally positive or emotionally neg

The membrane lipid-anchored glypicans (heparan sulfate proteoglycans) are present in both vertebrates and invertebrates and serve as important modulators of growth factors and morphogens during development. Their core proteins are similar and consist of a large N-terminal domain comprising 14 evolutionary conserved cysteines and a C-terminal stalk carrying the heparan sulfate side-chains and the l
