FMC—Earthquake Focal Mechanisms Data Management, Cluster and Classification [PDF]
Seismicity is frequently used to deduce the tectonics of a region. The study of earthquakes as a tectonic component, seismotectonics, has grown as one of the key research areas on active tectonics, especially from the analysis of earthquake focal ...

53BP1: function and mechanisms of focal recruitment
Biochemical Society Transactions, 200953BP1 (p53-binding protein 1) is classified as a mediator/adaptor of the DNA-damage response, and is recruited to nuclear structures termed foci following genotoxic insult. In the present paper, we review the functions of 53BP1 in DNA-damage checkpoint activation and DNA repair, and the mechanisms of its recruitment and activation following DNA damage.

Focal mechanism in the Apennines
Physics and Chemistry of the Earth, 1996Abstract This paper compares different source mechanism models that fit first onset amplitudes for a set of seismic events that occurred in the Apennines, Italy. We selected earthquakes of magnitude greater than 1.0 that match the criteria of appropriate instrumental coverage of the epicentral area, low localisation errors and high signal-to-noise ...

Mechanisms of focal ventricular tachycardia in humans
Heart Rhythm, 2009In classifying ventricular arrhythmias, a fundamental distinction is made between focal and macroreentrant mechanisms. Focal arrhythmias demonstrate early activation at a particular site with centrifugal spread of the impulse from this site of origin. In contrast, macroreentrant rhythms involve contiguous but spatially distributed areas of activation ...

Correlations of Earthquake Focal Mechanisms [PDF]
SUMMARY We performed a statistical analysis of the Harvard catalogue of seismic moment tensor solutions. We investigated the distribution of hypocentres on focal spheres of earthquakes. The hypocentres are concentrated along fault planes; the hypocentre distribution does not significantly differ for earthquakes in different depth ranges.

Physiological Mechanisms of Focal Epileptogenesis
Epilepsia, 1985Summary: The key elements in the development of epileptogenesis appear to be the capacity of membranes in some (pacemaker) neurons to develop intrinsic burst discharges, the presence of disinhibition, and the proper excitatory synaptic circuitry. It is likely that the relative role of each of these processes will differ at different sites in the ...

The mechanics of focal chondral defects in the hip
Journal of Biomechanics, 2017There is a mean incidence of osteoarthritis (OA) of the hip in 8% of the overall population. In the presence of focal chondral defects, defined as localized damage to the articular cartilage, there is an increased risk of symptomatic progression toward OA.
