Smooth muscle cells (SMCs) are organized in various patterns in blood vessels. Whereas straight blood vessels mainly contain circumferentially aligned SMCs, curved blood vessels are composed of axially aligned SMCs in regions with vortex blood flow. The vortex flow-dependent feature of SMC alignment suggests a role for nonuniform fluid shear stress in regulating the pattern formation of SMCs. H...

Vortex breaking has been traditionally studied for nonuniform critical current densities, although it may also appear due to nonuniform pinning force distributions. In this article we study the case of a high-pinning/low-pinning/high-pinning layered structure. We have developed an elastic model for describing the deformation of a vortex in these systems in the presence of a uniform transport cu...

Karp and Lipton introduced advice-taking Turing machines to capture nonuniform complexity classes. We study this concept for automata-like models and compare it to other nonuniform models studied in connection with formal languages in the literature. Based on this we obtain complete separations of the classes of the Chomsky hierarchy relative to advices.

New networks, called GLO networks, are constructed by adding bus-like links to omega networks, providing additional capacity between cells on momentarily busy paths. Equivalent pin-count GLO and omega networks offered uniform and nonuniform traffic were simulated. GLO networks exhibited lower latency for nonuniform traffic and light to moderate uniform traffic.

In this paper, we introduce the notion of biorthogonal wavelet packets associated with nonuniform multiresoltion analysis and study their characteristics by means of Fourier transform. Three biorthogonal formulas regarding these wavelet packets are established. Moreover, it is shown how to obtain several new Riesz bases of the space (R) by constructing a series of subspaces of these nonuniform ...

New networks, called GLO networks, are constructed by adding bus-like links to omega networks, providing additional capacity between cells on momentarily busy paths. Equivalent pin-count GLO and omega networks ooered uniform and nonuniform traac were simulated. GLO networks exhibited lower latency for nonuniform traac and light to moderate uniform traac.

A mostly-digital PWM-based delta-sigma (∆Σ) ADC is proposed. This system takes advantage of the duration of pulses, rather than voltage or current, as the analog operand used in its closed-loop operation. Therefore, circuits that process the pulses are digital in nature and improve with scaling. Furthermore, the architecture allows inherently matched multi-bit quantizer/DAC blocks by taking adv...

The classical WKS sampling theorem has been extended to the case of nonuniform sampling by numerous authors. For detailed information on the theory and its numerous applications, we refer to the book [15]. Most known irregular sampling results deal with Paley–Wiener functions which have L2(R) restrictions on the real line. It seems that the best known nonuniform WKS sampling results for entire ...

In this paper we investigate certain properties of the curves sk generated by a non-uniform variational refinement scheme defined over a k-window of some bi-infinite sequence of points. In particular, we show that error between sn and sk for k ≪ n over some fixed interval decays exponentially as k ↑ n, showing that sn can be well-approximated by sk for k much smaller than n. We use this result ...
