Localized changes in oxygen consumption related to increased neural activity can result in a small and transient "initial dip" of the blood oxygenation level-dependent (BOLD) signal used in functional magnetic resonance imaging (fMRI). The initial dip has been of great interest to the fMRI community because it may provide a more accurate and localized measure of neural activity than the convent...

Abstract The Shumagin seismic gap along the Alaska Peninsula experienced a major, M W 7.8, interplate thrust earthquake on 22 July 2020. Several available finite‐fault inversions indicate patchy slip of up to 4 m at 8–48 km depth. There are differences among models in peak and absolute placement plate boundary, resulting from data distributions, model parameterizations, inversion algorithms. Tw...

On 30 October 2020, a large Mw = 7.0 earthquake occurred north of the island Samos, Greece. Here we present characteristics seismic fault (location, geometry, geodetic moment) as inferred from processing data (InSAR and GNSS). We use InSAR displacement Sentinel-1 interferograms (ascending orbit 29 descending 36) GNSS offsets fourteen (14) stations in Greece Turkey to invert for parameters. Our ...

Seismic attribute analysis is important in subsurface data interpretation, such as seismic which could involve stratigraphic and structural interpretation. This interpretation often hampered by resolution and, sometimes, human inability to identify a subtle feature on the seismic. These factors have frequently led poor of geologic features. Thus, an integral approach studying patterns hydrocarb...

Here we present a joint analysis of the geodetic, seismological and geological data March 2021 Northern Thessaly seismic sequence, that were gathered processed as April 30, 2021. First, relocated seismicity from regional local networks inferred dip-direction (NE) dip-angle (38°) 3, rupture plane. Furthermore, used ascending descending SAR images acquired by Sentinel-1 satellites to map co-seism...

This investigation deals with a mathematical model for a distribution transformer including saturation effect. To this end, the equations related to a three phase transformer are specified and the effect of an inter-turn fault is included. Naturally by applying an inter-turn fault the inductance and resistance matrix will change. Thus, unknown quantities of inductances and resistances for compl...

On 19 January 2020, an Mw6.0 earthquake occurred in Jiashi County, Xinjiang, China. This is a strong that the Kepingtage Belt. The monitoring and inversion of co-seismic post-earthquake will help further understand geometry movement properties this tectonic belt. In study, Sentinel-1A images were used to analyze deformation post-seismic events. Okada elastic dislocation model was invert geometr...

Long-period surface waves recorded on the north-south Pasadena strainmeter are used to determine the seismic moments and fault parameters of the 19 May 1940 Imperial Valley, California, the 16 December 1954 Dixie Valley and Fairview Peak, Nevada, and the 18 August 1959 Hebgen Lake, Montana, earthquakes. Synthetic strain seismograms are matched with the observed strainmeter seismograms. Source p...

Abstract In normally consolidated, shallow (depth <~3 km) siliciclastic sequences, faults develop clay smears. Existing models include the dependence of permeability on fraction, but improved predictions fault should account for uncertainty and anisotropy. We introduce PREDICT, a methodology that computes probability distributions directional components (dip-normal, strike-parallel, dip-...
