TOPOLOGICAL MEANING OF GAUGE ANOMALY AND GAUSSIAN FACTORS
Modern Physics Letters A, 1993We consider 2n-dimensional non-Abelian gauge anomaly which is derived from (2n+2)-dimensional chiral anomaly using Gaussian factor regularization. Using this expression, we show explicitly the equivalence between the solution of Wess-Zumino condition obtained from (2n+2) dimensions and the anomaly given Fujikawa's method in arbitrary dimensions ...

Longitudinal and transverse gauge factors of polycrystalline strain gauges
Sensors and Actuators, 1984Abstract The gauge factor of strain gauges is calculated considering the longitudinal and transverse strain sensitivity of the resistivity. The general result is applied to free wire strain gauges, adhered foil strain gauges and thin film strain gauges. The relation between the gauge factor and the piezoresistive constant πl and πt is given and it is

Correction of Gauge Factor for Strain Gauges Used in Polymer Composite Testing
Experimental Mechanics, 2013Strain gauges are used together with the corresponding gauge factor to relate the relative electrical resistance change of the strain gauge with the strain of the underlying material. The gauge factor is found from a calibration on a stiff material - steel.

Factorization in extended electroweak gauge models
Physical Review D, 1981Extensions of the standard electroweak ${G}^{0}\ensuremath{\equiv}\mathrm{SU}{(2)}_{L}\ifmmode\times\else\texttimes\fi{}\mathrm{U}(1)$ gauge model, which include more neutral vector bosons, are strongly restricted but not excluded by the Hung-Sakurai (HS) factorization relations on neutrino-quark, neutrino-electron, and electron-quark amplitudes.

Behaviour of electrical resistance strain gauges at low temperatures II. Gauge factor
Cryogenics, 1967The authors continue their report of an investigation of the characteristics of strain gauges in the range 0—300° K from the previous paper with a study of ‘gauge factor’ G. Some results are given and the physical origin G is discussed.

Method for rapid determination of ion gauge sensitivity factors
Review of Scientific Instruments, 2007In ultrahigh vacuum thin film growth processes using gas phase growth precursors, the pressure of the gas at or near the substrate is a critical parameter since it is directly related to the collision frequency of the precursor with the substrate and ultimately to the growth rate.

Physical Review D, 1985
We prove Ward-type identities which are needed in the proof of factorization of the Drell-Yan process. Previous treatments prove them only for an axial gauge, and the proofs are diagrammatic in nature. We, on the other hand, establish the identities for the Feynman gauge and through symmetry considerations at the Lagrangian level.

Temperature dependence of gauge factor and magnetoresistance of some platinum-tungsten strain gauges
Journal of Physics E: Scientific Instruments, 1972The gauge factor of some Denfoil type 1831 NE foil gauges was found to increase monotonically by 5.7% of its room temperature value of 4.45 as the temperature was lowered to 4K. The magnetoresistance is negligible at room temperature and even at 4K and 1T is only equivalent to a strain of about 1.6*10-6, with an anisotropic part of about 0.5*10-6.

WEYL'S GAUGE TRANSFORM AND QUANTUM GEOMETRIC PHASE FACTORS
Modern Physics Letters A, 2007The historical and geometrical origin of Gauge Transformation and Yang's phase loop of gauge theory are discussed. In the present talk, we present the following points: 1. Parallel transport of a vector; 2. Weyl 1918 gauge transformation 3. Concept of non-integrable phase factor; 4. Berry's quantum geometrical phase; 5.
