Designing Power-Efficient Modulation Formats for Noncoherent Optical Systems [PDF]
, 2011 We optimize modulation formats for the additive white Gaussian noise channel with a nonnegative input constraint, also known as the intensity-modulated direct detection channel, with and without confining them to a lattice structure.

The module orthogonal to the specht module
Journal of Algebra, 1977 We adopt the notation of [3], so that when h = (A,, A, ,..., Ak) is a proper partition of n, MA is the permutation module of the symmetric group 6, on the subgroup GA1 x GA2 x 1.. x GA1 over some field F. The Specht module, 9, is a submodule of MA. Over a field of characteristic zero, the ordinary irreducible representations of 6, are given by the ...

Journal of Algebra, 1993 Let A and B be rings, A a subcategory of Mod-A closed under submodules and containing AA, and B a subcategory of Mod-B closed under direct sums and epimorphic images. Then any equivalence between A and B is represented by a bimodule APB with A=EndPB via the functors --⊗AP and HomB(P,–). This was proved by Menini and A. Orsatti [Rend. Sem. Mat.

Configurable Modulator for Pure Phase Modulation [PDF]
2019 Photonics North (PN), 2019 We present a configurable silicon modulator for pure phase modulation, implemented as a Mach-Zehnder interferometer with a PN carrier depletion modulator (CDM) and tunable couplers. The spurious intensity modulation introduced by the CDM is compensated by tuning the splitting ratios of the couplers and the phase delay between the arms.

Modules close to SSP- and SIP-modules [PDF]
Lobachevskii Journal of Mathematics, 2017 In this paper, we investigate some properties of SIP, SSP and CS-Rickart modules. We give equivalent conditions for SIP and SSP modules; establish connections between the class of semisimple artinian rings and the class of SIP rings. It shows that $R$ is a semisimple artinian ring if and only if $R_R$ is SIP and every right $R$-module has a SIP-cover ...

Frequency modulation of spin torque oscillator pairs
, 2011 The current controlled modulation of nano-contact based spin torque oscillator (STO) pairs is studied in both the synchronized and non-synchronized states. The synchronized state shows a well behaved modulation and demonstrates robust mutual locking even

$D$-module and $F$-module length of local cohomology modules [PDF]
Transactions of the American Mathematical Society, 2018 Let $R$ be a polynomial or power series ring over a field $k$. We study the length of local cohomology modules $H^j_I(R)$ in the category of $D$-modules and $F$-modules. We show that the $D$-module length of $H^j_I(R)$ is bounded by a polynomial in the degree of the generators of $I$.

Decompositions of modules into projective modules and CS-modules [PDF]
Bulletin of the Australian Mathematical Society, 2000 Let M be a right R-module. It is shown that M is a locally Noetherian module if every finitely generated module in σ[M] is a direct sum of a projective module and a CS-module. Moreover, if every module in σ[M] is a direct sum of a projective module and a CS-module, then every module in σ[M] is a direct sum of modules which are either indecomposable ...

Behavioral Neuroscience, 2008 Our memories are not all created equally strong: Some experiences are well remembered while others are remembered poorly, if at all. Research on memory modulation investigates the neurobiological processes and systems that contribute to such differences in the strength of our memories.
