A rigorous foundation is given for the logical formulation of process network synthesis on the basis of the combinatorial axioms of feasible processing networks. © 2000 Elsevier Science Ltd. All rights reserved.

Abstract The intertwined ferroelectricity and band topology will enable the non-volatile control of topological states, which is importance for nanoelectrics with low energy costing high response speed. Nonetheless, principle to design such system unclear feasible approach achieve coexistence two parameter orders absent. Here, we propose a general paradigm 2D ferroelectric insulators by sliding...

The species abundance distribution (SAD) is one of the most intensively studied distributions in ecology and its hollow-curve shape is one of ecology's most general patterns. We examine the SAD in the context of all possible forms having the same richness (S) and total abundance (N), i.e. the feasible set. We find that feasible sets are dominated by similarly shaped hollow curves, most of which...

We consider a two-player, sequential location game in d-dimensional Euclidean space with arbitrarily distributed consumer demand. The objective for each player is to select locations so as to maximize their market share—the mass of consumers in the vicinity of their chosen locations. At each stage, the two players (Leader and Follower) choose one location each from a feasible set in sequence. W...

Many crowd ideation systems seek to gather scores of ideas from people online. However, this often leads to many bad ideas and duplication. A dedicated facilitator who guides exploration of the solution space is a common and effective strategy for optimizing ideation in face-to-face brainstorming, but has not yet been explored in computer-supported crowd ideation. We introduce IdeaGens, a socia...
