Pure-Direct-Injective Modules

Lobachevskii Journal of Mathematics, 2022
The abstract of this paper gives a good idea of its content: ``In this paper, we study the class of modules having the property that if any pure submodule is isomorphic to a direct summand of such a module then the pure submodule is itself a direct summand. These modules are termed as pure-direct-injective modules (or pure-C2 modules).

Direct Imaging of Charge Modulation

Physical Review Letters, 1996
Electron diffraction calculation suggest that a modulation in the density of valence electrons may dominate the images of Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8+{delta}} under certain experimental conditions. This prediction is supported by electron microscope experiments where we observe modulation that we attribute to charge transfer over a distance of

Direct sums of ADS* modules

Boletín de la Sociedad Matemática Mexicana, 2015
Let \(R\) be an associative ring with an identity element. A unital right \(R\)-module \(M\) is called ADS* if for any direct summand \(N\) of \(M\) and any supplement \(K\) of \(N\) in \(M\) one has \(M=N\oplus K\). The aim of this paper is to investigate direct sums of ADS* modules. First, the authors provide a bunch of examples of ADS* modules whose

Specification directed module testing

IEEE Transactions on Software Engineering, 1986
The testing techniques described in this paper apply to the testing of abstract data types (modules, packages). The techniques utilize information generated during refinement of a data type, such as the data type invariant and the relationship between the specification and implementation states; this information is used to specify parts of the code to ...

On weakly directing modules

Communications in Algebra, 2000
Let A be an artin algebra. An indecomposable A-module M is called weakly directing if it does not belong to a cycle of nonzero nonisomorphisms between indecomposable modules from the same component of . This paper deals with weakly directing modules. We investigate the distinctions and connections between weakly directing modules and directing modules.

Direct injective modules

Acta Mathematica Sinica, 1993
Direct injective modules were defined by W. K. Nicholson in 1976. An \(R\)- module \(M\) is said to be direct injective if given a direct summand \(N\) of \(M\) with inclusion \(i: N\to M\) and any monomorphism \(g: N\to M\), there exists an endomorphism \(f\) of \(M\) such that \(fg=i\).

Direct RF Modulation Transmitter

PROBLEM TO BE SOLVED: To provide a direct RF modulation transmitter capable of saving more power consumption. SOLUTION: The direct RF modulation transmitter comprises: a passive mixer circuit 100 which inputs digital baseband data D of 1 bit, inverted data DN, a first RF signal, and a second RF signal whose phase is different from that of the first RF ...
