Relative precision of linkage mapping in recombinant diploid populations
Canadian Journal of Plant Science, 2007 With the increased effort in mapping linked loci, it is important to understand how the precision of the estimate of linkage intensity is influenced by the level of inbreeding and the sample size. For discreet traits, such as molecular markers, the standard error of linkage intensity has been determined for an F2 and backcross population. However, the

Precise Relative Positioning for Tandem Drifting Cars
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2021Drifting provides insights into how autonomous cars handle excursions past stable limits. So far, autonomous drifting has been demonstrated for a single car where GPS carrier phase measurements provide cm-level accuracy in absolute position via base station corrections. We aim to extend the single car drifting to tandem drifting. However, in autonomous

Precision Experimental Verification of Special Relativity
Physical Review Letters, 1978We compare the results of precision electron $g$-factor experiments at low energy and at 110 keV. The agreement between these measurements constitutes the most precise laboratory confirmation to date of the predictions of special relativity. Relativistic electromagnetic theory and Thomas precession are verified in this test.

Technique for precision beveling of relatively large micropipettes
Journal of Neuroscience Methods, 1979A technique is described for embedding various sizes of diamond dust in a film of Varathane laid upon an optically flat glass surface. This forms a precise and very durable abrasive surface. When such abrasive surfaces are used with previously described equipment, micropipettes may be beveled rapidly and reliably to tip diameters extending from 0.5 ...

Significance of precision tests of special relativity
Physics Letters A, 1993Abstract Recent experiments using two-photon absorption and phase comparison of masers can set bounds on Lorentz-violating preferred-frame alternatives to special relativity, but cannot give empirical knowledge concerning the one-way speed of light, since the latter depends on the synchronisation convention.

Precise relative cross sections for np scattering
Nuclear Physics A, 1994Abstract We present data on the differential cross section for neutron-proton scattering for an incident neutron energy of 67 MeV. These data allow a precise determination of the 1P1 phase which, in phase-shift analyses, is strongly correlated with the S-D amplitude which we are measuring via different observables.

Precise Relative Earthquake Magnitudes from Cross Correlation
Bulletin of the Seismological Society of America, 2015Abstract We present a method to estimate precise relative magnitudes using cross correlation of seismic waveforms. Our method incorporates the intercorrelation of all events in a group of earthquakes, as opposed to individual event pairings relative to a reference event. This method works well when a reliable reference event does not exist.

Precise relative rotation sensing using slow light
Chinese Physics B, 2010A novel relative rotation sensor based on slow light is proposed and analysed. A theoretical analysis shows that the high sensitivity of the proposed rotation sensor is achieved through an electromagnetically-induced-transparency medium. Unlike the tradition detection method, the idea of rotation sensing is to detect group delay between counter ...

High-Precision, Symplectic Numerical, Relative Orbit Propagation
Journal of Guidance, Control, and Dynamics, 2007This paper presents a numerical method to propagate relative orbits. It can handle an arbitrary number of zonal and tesseral terms in the geopotential. This method relies on defining a relative Hamiltonian, which describes both the absolute and the relative motion of two satellites.
