The so-called 'read' and 'write' barriers present an obstacle to the efficient execution of persistent programs that use a volatile object buffer, nonvolatile object store memory model. The barriers, implemented as checks added to the code, are required to ensure that objects are moved from store to buffer before being used and, if updated in the buffer, that they are written back on periodic c...

Medication is applied to the HIV-infected nodes of high-risk contact networks with the aim of controlling the spread of disease to a predetermined maximum level. This intervention, known as pinning control, is performed both selectively and randomly in the network. These strategies are applied to 300 independent realizations per reference level of incidence on connected undirectional networks w...

We present a model of flux pinning in a superconductor with relatively large nonsuperconducting spherical particles. Minimizing the total energy of a pinned vortex bundle we deduce equations for pinning force and critical current density. The calculated field dependencies of both quantities are in a good agreement with the earlier reported empirical formula and numerous experimental data for RE...

We describe the motion of interfaces in a two-dimensional discrete environment by coupling the minimizing movements approach by Almgren, Taylor and Wang and a discrete-to-continuous analysis. We show that below a critical ratio of the time and space scalings we have no motion of interfaces (pinning), while above that ratio the discrete motion is approximately described by the crystalline motion...

Measuring the ac magnetic response of a type II superconductor provides valuable information on the pinning landscape (pinscape) of the material. We use strong pinning theory to derive a microscopic expression for the Campbell length λ(C), the penetration depth of the ac signal. We show that λ(C) is determined by the jump in the pinning force, in contrast to the critical current j(c), which inv...

Controlling the pinning of organic droplets on solid surfaces is of fundamental and practical interest in the field of material science and engineering, which has numerous applications such as surface cleaning, water treatment, and microfluidics. Here, a rapid in situ control of pinning and actuation of organic droplets is demonstrated on dodecylbenzenesulfonate-doped polypyrrole (PPy(DBS)) sur...
