The capacity of a discrete memoryless channel (DMC) P S (yjx), with (random) state information S 2 S available at the transmitter, is given by the capacity of an equivalent DMC with an extended input space X jSj commonly interpreted as a space of strategies. This well known solution, due to Shannon, is in general hard to compute and apply. We consider the special case of a symmetric (modulo-add...

In this study, we present an innovative mathematical modeling approach that allows detailed characterization of Ca(2+) movement within the three-dimensional volume of an atrial myocyte. Essential aspects of the model are the geometrically realistic representation of Ca(2+) release sites and physiological Ca(2+) flux parameters, coupled with a computationally inexpensive framework. By translatin...

The IBM eServer zSeries FCP (Fibre Channel Protocol for SCSI) channel provides “Linux for zSeries” the capability to access storage devices using SCSI and FCP protocols, thus enabling it to make use of distributed storage. Leveraging the zSeries-unique virtualization approach for industry-standard storage devices as well, the zSeries FCP channel provides unique value in UNIX and Linux environme...

Numerical results and conclusions: Although the previous analysis also applies to frequency selective channels, for simplicity we consider the example of a flat fading channel with the channel impulse response z(r, I ) = [c0 + a,z , ( f ) ]S(r ) , where x: is the power gain of the diffise beam and z,(l) is a zero-mean, unit variance complex Gaussian random process representing the time-varying ...

The mixing of a new Z ′ boson with the Z significantly improves the fit to the LEP precision electroweak data, provided that the Z ′ couples mainly to quarks. If M Z 2 < 200 GeV, the s-channel Z 2 production and (W, Z, γ)Z 2 pair production cross sections at the Tevatron give an excess above QCD of b ¯ b and (W, Z, γ)b ¯ b events, respectively, with invariant mass m(b ¯ b) ≈ M Z 2 , which provi...

In this project, the behavior of Generalized Approximate Message-Passing Decoder for BSC and Z Channel is studied using i.i.d matrices for constructing the codewords. The performance of GAMP in AWGN Channel is already evaluated in the previous scientific work of Jean Barbier[1], therefore, this project mainly focuses on the performance of GAMP decoder for BSC and Z Channel. We evaluate the perf...

A multi-Higgs model with an extra neutral gauge boson (Z ′) is introduced. One scalar Higgs boson (H 2) in this model decays dominantly into a photon pair. The Z ′ decay to µ + µ − gets a much larger branching ratio than the Z decay to this channel. The ZZ ′ H 2 vertex provides a final state from Z decay resembling the new l + l − γγ events at the LEP. Other promising phenomenology, such as Z →...

The CH(X(2)Π) + propene reaction is studied in the gas phase at 298 K and 4 Torr (533.3 Pa) using VUV synchrotron photoionization mass spectrometry. The dominant product channel is the formation of C4H6 (m/z 54) + H. By fitting experimental photoionization spectra to measured spectra of known C4H6 isomers, the following relative branching fractions are obtained: 1,3-butadiene (0.63 ± 0.13), 1,2...

Costa’s celebrated “writing on dirty paper” (WDP) shows that the powerconstrained channel Y = X + S + Z, with Gaussian Z, has the same capacity as the standard AWGN channel Y = X + Z, provided that the “interference” S (no matter how strong it is) is known at the transmitter. While this ability for perfect interference cancellation is very appealing, it relies heavily on the Gaussianity of the ...
