We model seismic and aseismic slip on the Japan megathrust in the area of theMw9.0, 2011 Tohoku-Oki earthquake based on daily time series from 400 GPS stations of the GEONET network and campaign measurements of six sea floor displacements. The coseismic and postseismic slip distributions are inverted simultaneously using principal component analysis-based inversion method (PCAIM). Exploring a w...

This paper reports a novel, low-cost, moderately sensitive, meso-scale accelerometer fabricated with spring steel foil and equipped with either a Hall Effect-based proximity sensor or a capacitive sensor. Since the sensitivity of a Hall Effect sensor is low, we attach a displacement-amplifying compliant mechanism (DaCM) to the proof-mass of the accelerometer to increase the overall sensitivity ...

A quantitative global sensitivity analysis (SA) is applied to the non-linear inversion of gravity changes and displacement data which measured in an active volcanic area. The common inversion of this data is based on the solution of the generalized Navier equations which couples both types of observation, gravity and displacement, in a homogeneous half space. The sensitivity analysis has been c...

in this study, displacement field around v-notches of a poly methyl metha crylate (pmma) specimen with tip cracks will be analyzed using digital image correlation technique. first intensity factor in combination with in-plane rigid body translations and rotation components will be determined by linear least squares fitting of the displacement field data to the corresponding relations among stre...

A finite-element model (FEM) incorporating geologic properties characteristic of a subduction zone is compared with FEMs approximating homogeneous elastic halfspaces (HEHS)s to investigate the effect of heterogeneity on coseismic and postseismic deformation predictions for the 1995 Colima-Jalisco M•o=8.0 earthquake. The FEMs are used to compute a coefficient matrix relating displacements at obs...

The recurrence intervals of repeating earthquakes on the San Andreas Fault in the Loma Prieta aftershock zone follow the characteristic 1/t decay of Omori’s law. A model in which these earthquakes occur on isolated patches of the fault that fail in stick-slip with creep around them can explain this observation. In this model the recurrence interval is inversely proportional to the loading rate ...

BACKGROUND The evidence linking knee kinematics and kinetics during a vertical drop jump (VDJ) to anterior cruciate ligament (ACL) injury risk is restricted to a single small sample. Still, the VDJ test continues to be advocated for clinical screening purposes. PURPOSE To test whether 5 selected kinematic and kinetic variables were associated with future ACL injuries in a large cohort of Norw...

objective: 22q11.2 chromosomal region is a hot spot for many cytogenetic rearrangements especially microdeletions which are responsible for digeorge and velocardiofacial syndromes. the most characteristic sign in these patients is congenital cardiac conotruncal anomalies. the gold standard diagnostic test for these microdeletions is fish (fluorescent in situ hybridization). however this diagnos...
