Magnetic Reconnection Onset via Disruption of a Forming Current Sheet by the Tearing Instability. [PDF]
Physical Review Letters, 2014 The recent realization that Sweet-Parker current sheets are violently unstable to the secondary tearing (plasmoid) instability implies that such current sheets cannot occur in real systems. This suggests that, in order to understand the onset of magnetic

Modification of Constrained Rod Casting Mold for New Hot Tearing Measurement [PDF]
Archives of Metallurgy and Materials, 2018 Hot tearing severity was evaluated in this experiment by introducing a new apparatus called Constrained Rod Casting Modified Horizontal (CRCM-Horizontal). Six constraint bars with different lengths can produce hot tearing on the cast sample.

Particle Energization in 3D Magnetic Reconnection of Relativistic Pair Plasmas
, 2011 We present large scale 3D particle-in-cell (PIC) simulations to examine particle energization in magnetic reconnection of relativistic electron-positron (pair) plasmas.

MAGNETIC RECONNECTION: RECURSIVE CURRENT SHEET COLLAPSE TRIGGERED BY “IDEAL” TEARING [PDF]
, 2015 We study, by means of MHD simulations, the onset and evolution of fast reconnection via the “ideal” tearing mode within a collapsing current sheet at high Lundquist numbers ( S ≫ 10 4 ?> ).

, 2015 We examine the effect of an external guide field and current sheet thickness on the growth rates and nature of three dimensional unstable modes of an electron current sheet driven by electron shear flow.

, 2012 In large hot tokamaks like JET, the width of the reconnecting layer for resistive modes is determined by semi-collisional electron dynamics and is much less than the ion Larmor radius.

Correlation between Tear Osmolarity and Tear Meniscus [PDF]
Optometry and Vision Science, 2014 To examine the relationship between tear meniscus height (TMH) and subjective meniscus grading (subjective tear meniscus [TM]) with tear osmolarity.Tear osmolarity measurements (using TearLab) and digital images of the TM were obtained in 177 consecutive patients undergoing an eye examination at our optometry clinic (Universidad de Santiago de ...

Effects of Line-tying on Resistive Tearing Instability in Slab Geometry
, 2015 The effects of line-tying on resistive tearing instability in slab geometry is studied within the framework of reduced magnetohydrodynamics (RMHD).\citep{KadomtsevP1974,Strauss1976} It is found that line-tying has a stabilizing effect.

Tearing Out the Income Tax by the (Grass)Roots [PDF]
, 2014 Landscapes are increasingly fragmented, and conservation programs have started to look at network approaches for maintaining populations at a larger scale. We present an agent-based model of predator–prey dynamics where the agents (i.e.
