Strong crustal earthquakes in Greece are typically followed by aftershocks, the properties of which important factors seismic hazard assessment. In order to examine earthquake sequences, we prepared an catalog comprising aftershock sequences with mainshocks Mw ≥ 5.5 from 1995 2021. Regional parameters were estimated highlight variations decay and productivity among regions similar seismotectoni...

Complex binary sequences are generated through the application of simple threshold, linear transformations to the logistic iterative map. Depending primarily on the value of its non-linearity parameter, the logistic map exhibits a great variety of behavior, including stable states, cycling and periodical activity and the period doubling phenomenon that leads to high-order chaos. From the real d...

results phylogenetic analysis of the partial ns5b region demonstrated the relatedness of isolate fsm165 to the new subtype reported from iran in 2006. moreover, some core/e1 and ns5b sequences that had a high level of similarity with fsm165 isolate were found through searching the hcv database. these sequences were previously either misclassified or could not be accurately classified. phylogene...

To develop spatially continuous seismicity models (earthquake probability distributions) from a given earthquake catalog, the method of kernel estimation has been suggested. Kernel estimations with a global (spatially invariant) bandwidth deal poorly with earthquake hypocenter distributions that have different spatially local features. For example, a typical earthquake catalog has several areas...

In subduction zones, fluids are often invoked to explain slip processes on the megathrust, from great earthquakes slow-slip events and tectonic tremors. However, it is unclear how transient evolution of pore-fluid controlled by depth-dependent variations in hydraulic properties over a broad range timescales concomitant with full spectrum seismic aseismic slip. this study, we leverage newly-deve...

1. SUMMARY Time-series, or time-sequence, data show the value of a parameter over time. A common query with time-series data is to find all sequences which are similar to a given sequence. The most common technique for evaluating similarity between two sequences involves calculating the Euclidean distance between them. However, many examples can be given where two similar sequences are separate...

In this article, we propose an adaptive grid based on mesh equidistribution principle for two-parameter convection-diffusion boundary value problems with continuous and discontinuous data. A numerical algorithm based on an upwind finite difference operator and an appropriate adaptive grid is constructed. Truncation errors are derived for both continuous and discontinuous problems. Parameter uni...
