I believe these kinds of (co)limits are the ones defined in Gray's Formal Category Theory: Adjointness for $2$-categories I.7.9.1 (as quasi-(co)limits); some examples and computations of them are given further on in I.7.10, I.7.11 and I.7.12, and recover several classical constructions such as (co)comma objects or Eilenberg-Moore (or Kleisli) categories, as well as the usual description .

2 dimensional (2D) spread/chip-interleaved DS-CDMA is an MAI-free system, where single-user coherent frequency- domain equalization (FDE) can be used instead of complicated multiuser detection (MUD).

This special case allows for a rigorously defined Yang-Mills measure, meaning that the (Euclidean) path integral can be interpreted as a measure on the set of connections modulo gauge transformations.

Information-Theoretic Limits of Two-Dimensional Optical Recording Channels Paul H. Siegel . The electrocatalytic conversion of CO 2 into value-added chemicals is a promising approach to realize a carbon-energy balance. The requirements for semiconductors are well explored and could possibly be satisfied by a number of layered two-dimensional (2D) materials, such as transition metal dichalcogenides or black phosphorus.
