This paper investigates the distribution and nonuniform complexity of problems that are com plete or weakly complete for ESPACE under nonuniform reductions that are computed by polynomial size circuits P Poly Turing reductions and P Poly many one reductions A tight exponential lower bound on the space bounded Kolmogorov complexities of weakly P Poly Turing complete problems is established A Sma...

Purpose. Striatal single photon emission computed tomography (SPECT) imaging of the dopaminergic system is becoming increasingly used for clinical and research studies. The question about the value of nonuniform attenuation correction has become more relevant with the increasing availability of hybrid SPECT-CT scanners. In this study, the value of nonuniform attenuation correction and correctio...

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...

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.

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 ...

A truly functional Bayesianmethod for detecting temporally differentially expressed genes between two experimental conditions is presented. The method distinguishes between two biologically different set ups, one in which the two samples are interchangeable, and one in which the second sample is a modification of the first, i.e. the two samples are non-interchangeable. This distinction leads to...
