Maximum likelihood decoding algorithms for Gaussian MIMO linear channels are considered. Linearity over the field of real numbers facilitates the design of maximum likelihood decoders using number theoretic tools for searching the closest lattice point. These decoders are collectively referred to as sphere decoders in the literature. In this paper, a fresh look at this class of decoding algorit...

In this paper, we discuss the incorporation of dynamic subgrid scale (SGS) models in the lattice-Boltzmann method (LBM) for large-eddy simulation (LES) of turbulent flows. The use of a dynamic procedure, which involves sampling or test-filtering of super-grid turbulence dynamics and subsequent use of scale-invariance for two levels, circumvents the need for empiricism in determining the magnitu...

Stress granules (SGs) are large cytoplasmic ribonucleoprotein complexes that are assembled when cells are exposed to stress. SGs promote the survival of stressed cells by contributing to the reprogramming of protein expression as well as by blocking pro-apoptotic signaling cascades. These cytoprotective effects implicated SGs in the resistance of cancer cells to radiation and chemotherapy. We h...

In this thesis, we study the performance of the maximum-likelihood soft-decision sequential decoding algorithm (MLSDA) for convolutional codes, which is previously proposed in [1]. Instead of using the conventional Fano metric, the proposed algorithm employs a new metric based on a variation of the Wagner rule, which is referred to as the second form of the maximum-likelihood decoding rule. The...

In this paper, the service guaranteed scheduling model was proposed for the MPMS switching fabric. Firstly, the service distribution characteristic of each cell flow was analyzed in the MPMS switching fabric. Then, the service guaranteed distributed architecture was designed, and the scheduling model is proposed for demultiplexors, multiplexors, input switching units, middle switching units and...

Enhanced and immediate expression of cyclooxygenase-2 (COX-2) mRNA is observed in IL-1β-stimulated OA chondrocytes but the synthesis of protein found significantly delayed. Here we investigated the role of stress granules (SGs), ribonucleoprotein complexes that regulate mRNA translation, in the delayed translation of COX-2 mRNAs in IL-1β-stimulated OA chondrocytes. Stimulation of human chondroc...

The recent emergence of the discrete fractional Fourier transform has spurred research activity aiming at generating Hermite-Gaussian-like (HGL) orthonormal eigenvectors of the discrete Fourier transform (DFT) matrix F. By exploiting the unitarity of matrix F – resulting in the orthogonality of its eigenspaces pertaining to the distinct eigenvalues – the problem decouples into finding orthonorm...
