Abstract We address aseismic fault slip and the onset of seismicity resulting from depletion-induced or injection-induced stresses in reservoirs with pre-existing vertical inclined faults. Building on classic results, we discuss semi-analytical modelling techniques for including dislocation theory, Cauchy-type singular integral equations use Chebyshev polynomials their solution an eigenvalue-ba...

In this paper a CPW-fed annular slot antenna is miniaturized with enhanced impedance bandwidth using a reactive impedance surface (RIS) substrate. The RIS is realized by patterning 3× 3 array of circular elements over an inexpensive FR-4 substrate which is backed by a circular metallic plane. Due to the compensation of electric and magnetic energy stored by antenna and RIS substrate respectivel...

We report here the resection of a radiation-induced sarcoma (RIS) of the left clavicle developed in a 59-year-old woman 13 years after radiation for breast cancer. Surgery consisted of extirpation of the tumor with a combined resection of the total layer of the chest wall, the left brachiocephalic vein, and the left subclavian vein, reconstructed with a pediculated musculocutaneous graft using ...

The development of a radiation-induced sarcoma (RIS) in the post mastectomy thoracic treatment volume is an infrequent, but recognized, event. Its frequency is rising in relation with increasing survival of breast cancer patients treated with adjuvant radiation therapy, and is associated with poor prognosis despite treatment. We present a case of leiomyosarcoma in a patient who underwent mastec...

Abstract Identifying and monitoring the presence of pressurized magma beneath volcanoes allows for improved understanding internal dynamics prediction eruptions. Here we show with time-repeated tomography clear evidence that fresh melts accumulate since 2019 in three reservoirs located at different depths central feeding system. In these volumes, observe a significant reduction seismic wave vel...

The responses of the Ross Ice Shelf (RIS) to the 16 September 2015 8.3 (Mw) Chilean earthquake tsunami (>75 s period) and to oceanic infragravity (IG) waves (50–300 s period) were recorded by a broadband seismic array deployed on the RIS from November 2014 to November 2016. Here we show that tsunami and IG-generated signals within the RIS propagate at gravity wave speeds ( 70 m/s) as water-ice ...

Kieffer, S.W., 1984. Seismicity at Old Faithful Geyser: an isolated source of geothermal noise and possible analogue of volcanic seismicity.A., is a relatively isolated source of seismic noise and exhibits seismic behavior similar to that observed at many volcanoes, including "bubblequakes" that resemble B-type "earthquakes", harmonic tremor before and during eruptions, and periods of seismic q...
