Low‐Frequency Microwave Absorption Composites

open access: yesAdvanced Science, EarlyView.
The microwave absorption principles and low‐frequency performance factors are briefly introduced. Recent progress is systematically summarized in five different based composites. Then detailed analysis focuses on relationships and mechanisms about micro‐structure and macro‐performance.

Electrochemical Doping for Absorption and Conductivity Tuning of P(NDI2OD‐T2) Films

open access: yesAdvanced Electronic Materials, EarlyView.
Electrochemical doping of P(NDI2OD‐T2) films allows for tuning the degree of doping both in liquid electrolytes as well as in the solid state. The nature of the doped species is elucidated by UV–vis spectroscopy and accompanying DFT calculations. Correlations between maximum conductivities and the presence of mixed valence states, (specifically neutral/

On Relation between Constraint Answer Set Programming and Satisfiability Modulo Theories

open access: yes, 2016
Constraint answer set programming is a promising research direction that integrates answer set programming with constraint processing. It is often informally related to the field of satisfiability modulo theories.

Symmetries in Linear and Integer Programs

open access: yes, 2009
The notion of symmetry is defined in the context of Linear and Integer Programming. Symmetric linear and integer programs are studied from a group theoretical viewpoint. We show that for any linear program there exists an optimal solution in the fixed point set of its symmetry group.
