ℵ0-Distributive modules and rings
International Journal of Algebra and Computation, 2023Let A be a ring with minimum condition on principal right ideals. It is proved that countably distributive right (left) A-modules coincide with Artinian (Noetherian) right (left) A-modules. Rings, over which all right modules are [Formula: see text]-distributive coincide with rings of finite representation type.

, 2012 Plane modules and distributivity
Russian Mathematical Surveys, 1995A module \(M_A\) is flat iff every cyclic submodule of \(M\) is contained in a flat submodule of \(M\), and \(MB\cap MC=M(B\cap C)\) for any finitely generated left ideals \(B\), \(C\) of the ring \(A\). By similar means are described the situations when all submodules of \(M_A\) are flat and when all submodules of flat (right or left) modules over \(A\

Distributive and Multiplication Modules and Rings
Mathematical Notes, 2004All rings are assumed to be associative and to have non-zero identity. An \(A\)-module \(M\) is called a: (i) distributive module (for brevity, d-module) if the lattice of its submodules is distributive; (ii) multiplication module (for brevity, m-module) if for every submodule \(N\) of \(M\) there exists an ideal \(B\) of \(A\) such that \(N=MB\).

Distributed modulation for cooperative wireless communications
IEEE Signal Processing Magazine, 2006we examine the modulation aspect for data for- warding in wireless relay networks. We consider both distributed coherent and distributed differential detection schemes to handle two different cases when the channel state information (CSI) can be reliably estimated at the receiving nodes and when it cannot. We analyze both amplify-and-forward and decode-

Evaluation of temperature distribution of LED module
Microelectronics Reliability, 2013Abstract For high-power light-emitting diodes, heat management and reliability are important issues. The reliability and long lifetime of solid state lighting are especially essential in the high temperature applications, such as street lighting and automotive lighting. Because of the characteristics of semiconductor, the electrical property of light-

Structure and distribution of modules in extracellular proteins
Quarterly Reviews of Biophysics, 1996It has become standard practice to compare new amino-acid and nucleotide sequences with existing ones in the rapidly growing sequence databases. This has led to the recurring identification of certain sequence patterns, usually corresponding to less than 300 amino-acids in length.
