Fast reconnection in relativistic plasmas: the magnetohydrodynamics tearing instability revisited [PDF]
, 2016 Fast reconnection operating in magnetically dominated plasmas is often invoked in models for magnetar giant flares, for magnetic dissipation in pulsar winds, or to explain the gamma-ray flares observed in the Crab nebula, hence its investigation is of ...

Tomographic Imaging of Slab Segmentation and Deformation in the Greater Antilles
Geochemistry, Geophysics, Geosystems, 2018 We present a new tomographic P wave model of the upper mantle in the east Caribbean region. The model was built using 3‐D finite frequency sensitivity kernels and ~20,000 teleseismic P and PP traveltime residuals from 535 events recorded across 130 ...

Anterior diffuse scleritis diagnosed as conjunctivitis
African Vision and Eye Health, 2012 This article presents a case of anterior diffuse scleritis that initially was diagnosed as conjunctivitis. Anterior diffuse scleritis (ADS) is a potentially vision-threatening inflammation of the sclera whose etiology may include autoimmune and systemic ...

Direct Evidence of Magnetic Reconnection Onset via the Tearing Instability
Frontiers in Astronomy and Space Sciences, 2022 Magnetic reconnection is a sporadic process responsible for energy release in space and laboratory plasmas. It is believed that the tearing mode instability may be responsible for the onset of reconnection in the magnetotail.

Optimal Energy Growth in Current Sheets [PDF]
, 2017 In this paper, we investigate the possibility of transient growth in the linear perturbation of current sheets. The resistive magnetohydrodynamic (MHD) operator for a background field consisting of a current sheet is non-normal, meaning that associated ...

Urban transformations in “Roma Capitale”. The "Wrecks" of the Rione Ponte (1870-1970)
ArcHistoR Architettura Storia Restauro: Architecture History Restoration, 2017 All interventions made with the purpose of rendering Rome a modern city often revealed themselves as actual campaigns of destruction towards strengthened historical fabrics. In order to illustrate the dramatic extent that the regularly engineered tearing

AIP Advances, 2023 Via the two-field reduced magneto-hydrodynamics model, a self-consistent theory of tearing mode evolution is developed to study the stability of tearing mode in the resistive-inertial and viscous-resistive regimes.

Open Access Journal of Sports Medicine, 2010 The menisci are two semilunar-shaped fibrocartilagenous structures, which are interposed between the femoral condyles and tibial plateaux. They have an important role in knee function. Long-term follow-up studies showed that virtually all meniscectomized knees develop arthritic changes with time.

Tearing up the disc: misaligned accretion on to a binary [PDF]
, 2013 In a recent paper we have shown that the evolution of a misaligned disc around a spinning black hole can result in tearing the disc into many distinct planes.

A review on hot tearing of magnesium alloys
Journal of Magnesium and Alloys, 2016 Hot tearing is often a major casting defect in magnesium alloys and has a significant impact on the quality of their casting products. Hot tearing of magnesium alloys is a complex solidification phenomenon which is still not fully understood, it is of ...
