Optimum b value for resolving crossing fibers: a study with standard clinical b value using 1.5-T MR [PDF]
Neuroradiology, 2010 We sought to investigate the optimum b value for resolving crossing fiber using high-angular resolution diffusion imaging (HARDI)-based multi-tensor tractography. The study tested the standard b values that are commonly used in the routine clinical setting.Ten normal volunteers (five men and five women) with a mean age of 26.3 years (range, 22-32 years)

Magnetic Resonance in Medicine, 2019 Intravoxel incoherent motion (IVIM) modeling for estimation of the diffusion coefficient (D) and perfusion fraction (f) is increasingly popular, but no consensus on standard protocols exists.

Why the Mw 6 parkfield earthquake expected in the 1985–1993 interval was postponed till 2004?
Geomatics, Natural Hazards & Risk, 2022 The earthquake prediction released by USGS in 1985 to the public stated that there was an Mw6.0 earthquake occurring in the Parkfield area by January 1993 with a 95% chance. This prediction has proved unsuccessful.

Axial Seamount: Periodic tidal loading reveals stress dependence of the earthquake size distribution (b value) [PDF]
Earth and Planetary Science Letters, 2018 Earthquake size–frequency distributions commonly follow a power law, with the b value often used to quantify the relative proportion of small and large events. Laboratory experiments have found that the b value of microfractures decreases with increasing

Entropy, 2019 The Gutenberg-Richter Law describes the frequency-magnitude distribution of earthquakes. A number of studies have shown that the slope (b value) of the relationship between frequency and magnitude decreased before large earthquakes.

INVESTIGATION OF b-VALUE VARIATIONS IN THE AFRICAN AND PARTS OF EURASIAN PLATES [PDF]
Science of Tsunami Hazards, 2017 Numerous earthquakes have occurred along the collision zones of the African and parts of Eurasian plates. Some of these earthquakes along these zones have generated tsunamis.

Engineering Fracture Mechanics, 2019 This work investigates the effect of finite size and evolution of fracture process zone on b-value of acoustic emission in concrete beams. It is shown that the AE b-value determined using the Gutenberg-Richter (GR) law varies with beam size and ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Asymptomatic infection poses a significant risk for children undergoing hematopoietic stem cell transplantation (HSCT). Pre‐transplant surveillance computed tomography (CT) is commonly used to identify occult infection, though its diagnostic yield remains uncertain.
