Discrimination of Microseismic Events in Coal Mine Using Multifractal Method and Moment Tensor Inversion

Fractal and Fractional, 2022
Discrimination of various microseismic (MS) events induced by blasting and mining in coal mines is significant for the evaluation and forecasting of rock bursts. In this paper, multifractal and moment tensor inversion methods were used to investigate the

First-Motion Focal Mechanism Solutions for 2015–2019 M ≥ 4.0 Italian Earthquakes

Frontiers in Earth Science, 2021
A list of 100 focal mechanism solutions that occurred in Italy between 2015 and 2019 has been compiled for earthquakes with magnitude M ≥ 4.0. We define earthquake parameters for additional 22 seismic events with 3.0 ≤ M < 4.0 for two specific key ...

First Focal Mechanisms of Marsquakes [PDF]

Journal of Geophysical Research: Planets, 2021
AbstractSince February 2019, NASA's InSight lander is recording seismic signals on the planet Mars, which, for the first time, allows to observe ongoing tectonic processes with geophysical methods. A number of Marsquakes have been located in the Cerberus Fossae graben system in Elysium Planitia and further west, in the Orcus Patera depression.

Pathogenetic mechanisms of focal cortical dysplasia [PDF]

Epilepsia, 2014
SummaryFocal cortical dysplasias (FCDs) constitute a prevalent cause of intractable epilepsy in children, and is one of the leading conditions requiring epilepsy surgery. Despite recent advances in the cellular and molecular biology of these conditions, the pathogenetic mechanisms of FCDs remain largely unknown.

Focal adhesions as mechanosensors: A physical mechanism [PDF]

Proceedings of the National Academy of Sciences, 2005
Focal adhesions (FA) are large, multiprotein complexes that provide a mechanical link between the cytoskeletal contractile machinery and the extracellular matrix. FA exhibit mechanosensitive properties; they self-assemble and elongate upon application of pulling forces and dissociate when these forces are decreased. We propose a thermodynamic model for

Analysis of two microearthquake swarms in Southeastern Sicily: evidence for active faults?

Annals of Geophysics, 2001
Two microearthquake swarms occurring in Southeastern Sicily during November 1999 and January 2000 were analysed with respect to their seismotectonic features.

A study of the properties of the tectonic structure of the Kryvyi Rih city based on statistical analysis of seismicity

Геофизический журнал, 2022
The article concerns results of studying two significant seismic events — an explosion (23.09.2020 09:00) and an earthquake (30.09.2020 20:00), which occurred in the area of the city of Kryvyi Rih.

Mechanisms of Scarring in Focal Segmental Glomerulosclerosis [PDF]

Journal of Histochemistry & Cytochemistry, 2019
Focal segmental glomerulosclerosis (FSGS) presents with scar in parts of some glomeruli and often progresses to global and diffuse glomerulosclerosis. Podocyte injury is the initial target in primary FSGS, induced by a circulating factor. Several gene variants, for example, APOL1, are associated with increased susceptibility to FSGS.
