In the MST reversed field pinch the radial profile of the plasma rotation undergoes a rapid flattening during magnetic reconnection events. The reconnection events are repetitive (occurring as sawtooth crashes) and correspond to bursts of tearing instabilities. The radial transport of toroidal and poloidal momentum occurs faster than can be explained by collisions. We measure the change in mome...

The ultimate aim of virtual reality is to present the user with an illusion of reality within a virtual environment. Visual artefacts that appear in a virtual reality system’s computer generated graphics can easily destroy this artificial sense of reality. Therefore in order to maintain an illusion of reality, it is essential to eliminate or hide such visual artefacts from the user. This paper ...

OBJECTIVE To investigate the existence of proprioceptive deficits between the injured limb and the uninjured (i.e. contralateral normal) limb, in individuals who suffered complete tearing of the anterior cruciate ligament (ACL), using a strength reproduction test. METHODS Sixteen patients with complete tearing of the ACL participated in the study. A voluntary maximum isometric strength test w...

The interlamellar biomechanical properties of stromal collagen are relatively unknown, yet may be highly significant with respect to wound healing and the efficacy of certain keratorefractive surgical procedures. Interlamellar adhesive strength was measured as the tearing force required to separate corneal lamellae at a 50% stromal depth in 16 human eyebank corneas. The mean value for the centr...

We examine the fracture mechanics of tearing graphene. We present a molecular dynamics simulation of the propagation of cracks in clamped, free-standing graphene as a function of the out-of-plane force. The geometry is motivated by experimental configurations that expose graphene sheets to out-of-plane forces, such as back-gate voltage. We establish the geometry and basic energetics of failure ...

A minimal self-consistent model of the multiscale interaction of a tearing mode with drift wave turbulence is presented. A tearing instability in a cylindrical plasma interacting with electrostatic drift waves is considered, for reasons of simplicity. Wave kinetics and adiabatic theory are used to treat the feedback of tearing mode flows on the drift waves via shearing and radial advection. The...

X-ray activity of Anomalous X-ray Pulsars and Soft Gamma-Ray Repeaters may result from the heating of their magnetic corona by direct currents dissipated by magnetic reconnection. We investigate the possibility that X-ray flares and bursts observed from AXPs and SGRs result from magnetospheric reconnection events initiated by development of tearing mode in magnetically-dominated relativistic pl...
