in this research the influence of adding sic on microstructure and electrical properties of zno-based nanocomposite varistors were investigated. sic was added with amounts of 10-0 mass% to zno-based varistor composition. it is found that sic allows reaching to high threshold voltage with formation of fine-grained zno.another important effect of adding sic is formation zn2sio4 (willemite) on the ...

OBJECTIVE The mechanism by which an electric field terminates arrhythmias continues to puzzle investigators. Existing experimental methods provide information about epicardial manifestations of electrical cardioversion, yet little is known about field effects deep inside the myocardium. Here we combine specially designed optical mapping experiments and computer modeling to separate the intra-my...

[1] Using a coupled model of intermediate complexity the sensitivity of the last glacial maximum (LGM) Atlantic meridional overturning circulation (AMOC) to the strength of surface wind-stress is investigated. A threshold is found below which North Atlantic deep water formation (DWF) takes place south of Greenland and the AMOC is relatively weak. Above this threshold, DWF occurs north of the Gr...

An algorithm is presented for error correction in the surface code quantum memory. This is shown to correct depolarizing noise up to a threshold error rate of 18.5%, exceeding previous results and coming close to the upper bound of 18.9%. The time complexity of the algorithm is found to be polynomial with error suppression, allowing efficient error correction for codes of realistic sizes.

We show how to construct a convolution kernel that has a desired anisotropic surface tension and desired anisotropic mobility to be used in threshold dynamics schemes for simulating weighted motion by mean curvature of interfaces, including networks of them, in both two and three dimensions. Moreover, we discuss necessary and sufficient conditions for the positivity of the kernel which, in the ...

Phonation threshold pressures (PTP) have been commonly used for obtaining a quantitative measure of vocal fold motility. However, as these measures are quite low, it is typically difficult to obtain reliable data. As the amplitude of an electroglottograph (EGG) signal decreases substantially at the loss of vocal fold contact, it is mostly easy to determine the collision threshold pressure (CTP)...

The effect of subcritical hadron bubbles on a first-order quark-hadron phase transition is studied. These subcritical hadron bubbles are created due to thermal fluctuations, and can introduce a finite amount of phase mixing (quark phase mixed with hadron phase) even at and above the critical temperature. For reasonable choices of surface tension and correlation length, as obtained from the latt...

The field of quantum computation currently lacks a formal proof of experimental feasibility. Qubits are fragile and sophisticated quantum error correction is required to achieve reliable quantum computation. The surface code is a promising quantum error correction code, requiring only a physically reasonable 2D lattice of qubits with nearest neighbor interactions. However, existing proofs that ...

The surface code scheme for quantum computation features a 2d array of nearestneighbor coupled qubits yet claims a threshold error rate approaching 1% [1]. This result was obtained for the toric code, from which the surface code is derived, and surpasses all other known codes restricted to 2d nearest-neighbor architectures by several orders of magnitude. We describe in detail an error correctio...
