Open source collaborations are increasingly among commercial rms whose interest is pro t. Why would pro t-motivated rms voluntarily share code? One reason is that cost reductions can outweigh increases in rivalry. This is especially persuasive when the contributors make complementary products. However, cost reductions do not explain why open source is a more pro table way of sharing than other ...

The package refers to the index-value method and, mo...

We have monitored a sample of 27 nearby globular clusters in the hard X-ray band (20 − 120 keV) for ∼1400 days using the BATSE instrument on board the Compton Gamma-Ray Observatory. Globular clusters may contain a large number of compact objects (e.g., pulsars or X-ray binaries containing neutron stars) which can produce hard Xray emission. Our search provides a sensitive (∼50 mCrab) monitor fo...

This paper describes RTL-lwIP, which is a TCP/IP stack for embedded systems based on lwIP (Lightweight TCP/IP stack) that runs on RT-Linux and can be used by real-time tasks. RTL-lwIP allows real-time tasks to communicate directly with remote real-time tasks or even with Linux user processes. The importance of introducing TCP/IP on RT-Linux is that it enables the possibility of developing real-...

There’s been much ado about the Android operating system lately. A good bit of the buzz has been the marketing hype and early adopter reviews that inevitably accompany the release of new products. But it’s not this buzz that’s so interesting; it’s the discussion about the open source licensing and copyright issues that Android has generated. Android presents some fascinating lessons and some th...

Currently, an anti-glycopeptidolipid (GPL)-core IgA antibody assay kit for diagnosing Mycobacterium avium complex (MAC) is commercially available. We conducted this systematic review and meta-analysis to reveal the precise diagnostic accuracy of anti-GPL-core IgA antibodies for MAC pulmonary disease (MAC-PD). We systematically searched reports that could provide data for both sensitivity and sp...

BACKGROUND AND PURPOSE Because thromboembolic events are frequently observed in primary antiphospholipid syndrome (PAPS), we assessed the risk factors for new thrombotic episodes. METHODS Fifty-six PAPS patients (mean age, 37+/-10 years) were prospectively studied for 5 years. The preliminary Sapporo classification criteria for antiphospholipid syndrome (APS; a medium-high anticardiolipin ant...

Analytical and geometrical properties of generalized power-law (GPL) density profiles are reviewed, and special effort is devoted to the special cases where GPL density profiles reduce to (i) a double power-law (DPL), and (ii) a single power-law (SPL). Then GPL density profiles are compared with simulated dark haloes (SDH) density profiles, and nonlinear least-squares fits are prescribed, invol...

Mycobacterium smegmatis has been widely used as a mycobacterial infection model. Unlike the M. smegmatis mc(2)155 strain, M. smegmatis J15cs strain has the advantage of surviving for one week in murine macrophages. In our previous report, we clarified that the J15cs strain has deleted apolar glycopeptidolipids (GPLs) in the cell wall, which may affect its morphology and survival in host cells. ...
