Inferring Orthologs: Open Questions and Perspectives

Microquasars: Open Questions and Future Perspectives

The discovery and subsequent study of microquasars lead to major progress in our understanding of: 1) the nature of relativistic jets seen elsewhere in the universe, and 2) the connection between the accretion onto compact objects and the formation of collimated jets. A detailed account of the major progress accomplished until present was published in Annual Review of Astronomy & Astrophysics (...

New perspectives in neurosteroid action: open questions for future research

Neurosteroids are still a hot topic in cellular and systemic neuroscience although the first report on anaesthetic actions of progesterone from Selye was published already in 1941 (Selye, 1941). It is a fascinating concept that endogenous metabolites of progesterone such as allopregnanolone and pregnanolone are powerful allosteric modulators of γ-aminobutyric acid type A (GABAA) receptors. This...

Randomness and Computability: Open Questions

4 Conclusions and Open Questions

arose naturally is: Is the bi diam always bounded by O(D 2) for graphs with diameter D ? A negative answer could imply a better lower bound. However, we have recently shown ((EMZ]) that bi diam(G) = (D 2 G), where G is any 2-edge connected graph, and thus the answer to the question is positive (this result was independently proved by D]). It implies that, using the same technique we used, one c...

The Rcwa Method - a Case Study with Open Questions and Perspectives of Algebraic Computations∗

Diffraction of light on periodic media represents an important problem with numerous physical and engineering applications. The Rigorous Coupled Wave Analysis (RCWA) method assumes a specific form of gratings which enables a straightforward separation of space variables. Using Fourier expansions, the solutions of the resulting systems of ordinary differential equations for the Fourier amplitude...
