Traditionally, political scientists define political institutions deductively. This approach may prevent from discovery of existing institutions beyond the definitions. Here, a principal component analysis was used for an inductive extraction of dimensions in Polity IV data on the political institutions of all nations in the world the last two centuries. Three dimensions of institutions were re...

Confronting the predictions of numerical calculations with observations is an important tool to progress with our understanding of the mechanism triggering the outbursts of dwarf novae and soft X-ray transients. Simultaneous multi-wavelength observations are of particular importance in this process as they contain information about the chronology of the outbursts as e.g. the famous UV-delay obs...

Although applied behavior analysts often say they engage in evidence-based practice, they express differing views on what constitutes "evidence" and "practice." This article describes a practice as a service offered by a provider to help solve a problem presented by a consumer. Solving most problems (e.g., increasing or decreasing a behavior and maintaining this change) requires multiple interv...

We discuss recent progress in the field of robust adaptive control with special emphasis on methodologies that use multiple-model architectures. We emphasize that the selection of the number of models, estimators and compensators in such architectures must be based on precise definition of the robust performance requirements. We illustrate some of the concepts and outstanding issues for a new m...

The purpose of this Letters section is to provide rapid dissemination of important new results in the jields regularly covered by Physics of Fluids B. Results of extended research should not be presented as a series of letters in place of comprehensive articles. Letters cannot exceed three printed pages in length, including space allowed for title, jigures, tables, references and an abstract li...

A real band condition is shown to exist for one dimensional periodic complex non-hermitian potentials exhibiting PT-symmetry. We use an exactly solvable ultralocal periodic potential to obtain the band structure and discuss some spectral features of the model, specially those concerning the role of the imaginary parameters of the couplings. Analytical results as well as some numerical examples ...

interactions with electrons and positrons. A broad spectrum of neutrino and antineutrino behavior is observed, ranging from vacuumlike to smooth. Oscillations exhibiting self-maintained coherence also appear. We identify a variety of neutrino properties arising as a consequence of the nonlinear neutrino self-interactions. The nonlinear effects tend to suppress any CP asymmetry relative to the l...

It is difficult to measure relative corporate real estate asset management performance, as different organizations require different outputs from their property assets. However, prior research has identified a number of input factors or dimensions relating to corporate real estate that tend to occur together in organizations exhibiting high levels of performance. This paper proposes a methodolo...
