Dirac Sea and Hole Theory for Bosons II -- Renormalization Approach -- [PDF]

open access: yes, 2006
In bosonic formulation of the negative energy sea, so called Dirac sea presented in the preceding paper [arXiv:hep-th/0603242], one of the crucial points is how to construct a positive definite inner product in the negative energy states, since naive ...

Constrained MLAMBDA Method for Multi-GNSS Structural Health Monitoring

open access: yesSensors, 2019
Deformation monitoring of engineering structures using the advanced Global Navigation Satellite System (GNSS) has attracted research interest due to its high-precision, constant availability and global coverage. However, GNSS application requires precise

Accuracy Evaluation of Ionospheric Delay from Multi-Scale Reference Networks and Its Augmentation to PPP during Low Solar Activity

open access: yesISPRS International Journal of Geo-Information, 2021
The Precise Point Positioning (PPP) with fast integer ambiguity resolution (PPP-RTK) is feasible only if the solution is augmented with precise ionospheric parameters.

The potential for super-Nyquist asteroseismology with TESS [PDF]

open access: yes, 2015
The perfect 30-min cadence of the full-frame images from the Transiting Exoplanet Survey Satellite (TESS) will impose a hard Nyquist limit of 24 d$^{-1}$ ($\approx 278$ $\mu$Hz).

PDF Evaluation of the Integer Ambiguity Residuals [PDF]

open access: yes, 2004
A parameter estimation theory is incomplete if no rigorous measures are available for validating the parameter solution. Since the classical theory of linear estimation does not apply to the integer GPS model, rigorous validation is not possible when use is made of the classical results.

Real Time Attitude Independent GPS Integer Ambiguity Resolution [PDF]

open access: yesThe Journal of the Astronautical Sciences, 2004
In this paper, a new motion-based approach for Global Positioning System (GPS) integer ambiguity resolution is derived. The approach first represents the GPS sightline vectors in the body frame or the baseline vectors in the reference frame. The solution to this problem is always available as long as at least three non-coplanar baseline or sightline ...

A sign assignment in totally twisted Khovanov homology

open access: yes, 2011
We lift the characteristic-2 totally twisted Khovanov homology of Roberts and Jaeger to a theory with integer coefficients. The result is a complex computing reduced odd Khovanov homology for knots.

Canonical Quantization of Gravitating Point Particles in 2+1 Dimensions [PDF]

open access: yes, 1993
A formalism previously introduced by the author using tesselated Cauchy surfaces is applied to define a quantized version of gravitating point particles in 2+1 dimensions.

Fractal Characterizations of MAX Statistical Distribution in Genetic Association Studies

open access: yes, 2009
Two non-integer parameters are defined for MAX statistics, which are maxima of $d$ simpler test statistics. The first parameter, $d_{MAX}$, is the fractional number of tests, representing the equivalent numbers of independent tests in MAX.
