We have searched for fluctuations in the steady-state tension developed by stimulated single muscle fibers. Such tension "noise" is expected to be present as a result of the statistical fluctuations in the number and/or state of myosin cross-bridges interacting with thin filament sites at any time. A sensitive electro-optical tension transducer capable of resolving the expected fluctuations in ...

In a simple connected undirected graph G, an ordered set R of vertices is called resolving if for every pair distinct u and v, there vertex w∈R such that d(u,w)≠d(v,w). A F the G fault-tolerant each v∈F, F∖{v} also G. this article, we determine optimal fault-resolving r-th power any path Pn when n≥r(r−1)+2. For other values n, give bounds size set. We have presented algorithm to construct Pmr f...

A multiple-reflection time-of-flight mass spectrometer (MR-TOF-MS) [1] will be an important part of the MATS/LaSpec beam-line at the Low-Energy-Branch (LEB) of the Super-FRS at FAIR. The MR-TOF-MS is a fast (∼ms), multi-purpose, non-scanning mass spectrometer with single-ion sensitivity and will be used as a broadband mass spectrometer, as isobar separator or for direct mass measurements of ver...

Laser diode beam divergence is the main parameter for beam shaping and fiber optic coupling. Increasing the waveguide layer thickness is the conventional method to decrease the beam divergence. In this paper, the broadened asymmetric waveguide is introduced to decrease the divergence without increasing the optical power. The asymmetric waveguide was used to shift the vertical optical field to n...

purpose: to compare the optical properties of hydrophilic and hydrophobic intraocular lenses (iols) containing uv-absorber and to determine their chemical composition. methods: optical properties of different foldable hydrophilic and hydrophobic as well as non-foldable hydrophobic polymethylmetacrylate (pmma) iols were evaluated in three powers of 15, 22 and 25 diopters. optical properties were...

The Center for Advanced Microstructures and Devices’(CAMD) aging plane-grating soft x-ray monochromator beamline was upgraded to a varied-line-space plane-grating monochromator (VLSPGM) beamline. Preliminary measurements indicate significant performance improvements in both the resolving power and the throughput over its predecessor. However, it was found that the VLSPGM has less than the calcu...

55th ASMS Conference – Indianapolis 2007 www.chemistry.wustl.edu/~msf/ Overview Purposes •Evaluate the resolving power and sensitivity achievable with a new compensated trap for FTMS as a function of m/z and develop a protocol for tuning this trap. Methods •Sample empirically the cyclotron frequency surface at various cyclotron radii and z-mode amplitude distributions. •Compare the mass resolvi...
