multimode fiber

An optical fiber with a larger core than singlemode fiber. It is the most commonly used fiber for short distances such as LANs. Light can enter the core at different angles, making it easier to connect the light source to broader light sources such as LEDs. However, light rays travel down multiple reflective paths (modes) in multimode fiber, causing modal dispersion, which is a broadening of the pulses at the receiving end. Contrast with singlemode fiber. See graded-index fiber, dispersion and fiber optics glossary.

While many libraries are on their second generation OPAC (and, perhaps, even their third now!), the MMF is taking advantage of new interfaces and tools from both OCLC (WorldCat) and RISM to bring awareness and searchability of its substantial and unique collections to the world via the Internet; and to support a symbiosis between these two world-class databases, which are seen to be the main tools students, musicians, researchers, and musicologists would use in their work.
Compared to MMF, CMF significantly selected higher overstory canopy (p < 0.001), farther water resources (p < 0.001) and lower grass coverage (p < 0.001), but no significant difference was found in those variables between CN and MN (Table 3).
MMF is an immunosuppressive prodrug of mycophenolic acid that reversibly inhibits inosine monophosphate dehydrogenase, leading to decreased B cell and T cell proliferation and decreased antibody production [8].
All patients received initial immunosuppres-sive therapy with prednisolone (P), antimetabolites (mycophenolatemofetil-(MMF), azathioprine-(AZA)) combined with calcineurin inhibitors (CNI; cyclosporin A-CyA/, tacrolimus-Tac), interleukin-2 receptor antagonists (IL-2ra) or mechanistic target of rapamycin (mTOR) inhibitors (sirolimus(SRL)/ everolimus (EVL)).
