Diagnostic value of multi-b-value DWI for endometrial carcinoma and the optimal b value exploring

ISMRM Annual Meeting
Selecting the appropriate b value in DWI scanning to maximize the signal difference between endometrial tissues with different properties is conducive to the detection and accurate diagnosis of the endometrial lesion. The multiple b value DWI, especially b value > 1000 s/mm2, may play a crucial role in the detection of EC.

Seismic magnitudes, entropy and b-value

Acta Geophysica
How seismic magnitudes are distributed is important for estimating stress levels in seismic hazard studies, and two methods of characterizing the magnitude distribution are through the Gutenberg-Richter b-value, or equivalently through , and through the information entropy.

On the variation of b-values with earthquake size

Physics of the Earth and Planetary Interiors, 1994
Abstract We investigate the effect on Gutenberg and Richter's parameter b of the saturation of moment-magnitude relationships caused by source finiteness. Any conventional magnitude scale measured at a constant period features a saturation which results in a stepwise increase in the slope of the log10 moment-magnitude relationship.

B-value and Optical Fiber Lifetime

MRS Proceedings, 1998
AbstractIn this work we analyze the existing literature relating to the B-value and the inert strength measurements. The weak flaw statistic model for fiber lifetime estimation is considered with regard for the two-region crack growth.

Spatial Variations of Seismic B-Values Distribution in China

Applied Mechanics and Materials, 2011
Seismic frequency-magnitude relationship has been investigated in China, based on the earthquake data in the range ofM3.0 toM7.0 during the years 1986-2008, to study the potential of variations ofb-values with the depth. According to the results, there is a systematic decrease inbvalue with increasing depth of earthquakes.

Local b-values related to seismicity

Tectonophysics, 1974
Abstract To find a method by which the Caracas earthquake of July 29, 1967 could have been foreseen, a total of thirteen years of continuous seismographic records, recorded at the Seismological Institute Caracas (CAR), have been used to summarize the local seismic activity, in function of time and magnitude.

B-valued Chebyshev polynomials and the free Poincaré inequality for B-valued semi-circular systems

International Journal of Mathematics
We characterize [Formula: see text]-valued semi-circular systems in terms of a [Formula: see text]-valued free probabilistic analogue of Poincaré inequality. This is a [Formula: see text]-valued generalization of Biane’s theorem (see Theorem 5.1 in [P. Biane, Logarithmic Sobolev inequalities, matrix models and free entropy, Acta Math. Sin. (Engl. Ser.)

The effect of the magnitude uncertainty on the b value

Acta Seismologica Sinica, 2000
Since the magnitude is usually not the same from one catalog to another for the same earthquake, the calculated b value will change with different catalogs. Big b error is usually introduced when the magnitudes of the events are not well measured. For this reason, based on the uncertainty of the observed magnitude, i.e., the ‘apparent’ magnitude, the ...
