In this paper, we consider the frequency offset estimation for Orthogonal Frequency-Division Multiple Access (OFDMA) uplink (UL) transmissions. We first analyze the negative effect of Multi-Access-Interference (MAI) on OFDMA UL, and then propose two interference reduction/elimination methods, i.e., the Reduced-Rank-Projector (RRP) and Shift-Sampling-Projector (SSP) methods, to eliminate/reduce ...

the word relation is a new concept that did not used in its today`s meaning one hundred and fifty years ago. in spite of this situation, its substitute concepts like friendliness is used in nahj ul-balāghah many times and each of them express varieties & places in general relation between human and god and other relations. on the whole, we face four relations: human relation with god, himself a...

In this dataset, we analyzed galvanic-evoked head movements (GEHMs) in the spatial planes of yaw, and roll in normal and unilaterally labyrinthectomized (UL) Wistar rats. The rats were assigned in 4 groups of 10: control, sham, right-UL and left-UL. Bilateral galvanic vestibular stimulation (GVS) was presented by our "ring-shaped electrode" design (see "Short-term galvanic vestibular stimulatio...

This paper describes our efforts to create a Unified Lexicon by extracting information from a variety of external resources, namely our XLE syntactic lexicon, WordNet, Cyc, and VerbNet. The UL is built in several steps: first the information is extracted from the resources; then it is merged into lexical entries based on word stem, syntactic subcategorization frame, meaning concept, and WordNet...

We describe a class of C *-algebras which simultaneously generalise the ul-tragraph algebras of Tomforde and the shift space C *-algebras of Matsumoto. In doing so we shed some new light on the different C *-algebras that may be associated to a shift space. Finally, we show how to associate a simple C *-algebra to an irreducible sofic shift.

We discuss the fate of initial states of the cat type for the damped harmonic oscillator, mostly employing a linear version of the stochastic Schrödinger equation. We also comment on how such cat states might be prepared and on the relation of single realizations of the noise to single runs of experiments. Typeset using REVTEX 1

Analyses using simplified coupled-channels models have been unable to describe the shape of the previously measured fusion barrier distribution for the doubly magic O+Pb system. This problem was investigated by remeasuring the fission excitation function for O+Pb with improved accuracy and performing more exact coupled-channels calculations, avoiding the constant-coupling and first-order coupli...

Any charged particle moving faster than light through a medium emits Cherenkov radiation. We show that charged particles moving faster than light through the vacuum emit Cherenkov radiation. How can a particle move faster than light? The weak speed of a charged particle can exceed the speed of light. By definition, the weak velocity v w is Ψ f in |v|Ψ in /Ψ f in |Ψ in , where v is the velocity ...

The present paper can be considered as a natural extension the article [Ar7]. Fix root data (Y,X, . . . ) of the finite type (I, ·) and a positive integer number l. In [Ar7] we obtained a nice description for semiinfinite cohomology of the trivial module C over the small quantum group ul corresponding to the root data (Y,X, . . . ) in terms of local cohomology of the structure sheaf on the nilp...
