A large number of methods for multiple sequence alignment are currently available. Recent benchmarking tests demonstrated that strengths and drawbacks of these methods differ substantially. Global strategies can be outperformed by approaches based on local similarities and vice versa, depending on the characteristics of the input sequences. In recent years, mixed approaches that include both gl...

Iris recognition from surveillance-type imagery is an active research topic in biometrics. However, iris identification in unconstrained conditions raises many proplems related to localization and alignment, and typically leads to degraded recognition rates. While development has mainly focused on more robust preprocessing, this work highlights the possibility to account for distortions at matc...

Polarization at 800 and 1100 μm has been observed in the star-forming regions Mon R2, DR21 and W3-IRS4. These data have been used to test proposed mechanisms for producing polarized dust emission in the submillimetre. It was found that illumination effects are not sufficient to explain the observed polarization, and that some degree of grain alignment is required. In general, mechanical alignme...

Pairwise local alignment is one of the most important problems in sequence analysis in computational biology. Classical dynamic programming solution to this problem searches for two segments with maximum similarity score by discarding poorly conserved initial and terminal fragments. As a consequence, an alignment returned as optimal may contain a mosaic of well-conserved fragments arti cially c...

Most multi-alignment methods are fully automated, i.e. they are based on a fixed set of mathematical rules. For various reasons, such methods may fail to produce biologically meaningful alignments. Herein, we describe a semi-automatic approach to multiple sequence alignment where biological expert knowledge can be used to influence the alignment procedure. The user can specify parts of the sequ...

In multi-Higgs-doublet models, the alignment in flavour space of all Yukawa matrices coupling to a given right-handed fermion guarantees the absence of tree-level flavour-changing neutral couplings, while introducing new sources of CP violation. With N Higgs doublets (and no right-handed neutrinos) the Yukawa Lagrangian is characterized by the fermion masses, the CKM quark mixing matrix and 3(N...

In this paper, we present a floorplanning algorithm based on sequence pair representation. Our floorplanner has the following important features: 1) It is explicitly designed for fixed-frame floorplanning, which is different from traditional well-researched minarea floorplanning. Moreover, we also show that it can be adapted to minimize total area. 2) It addresses the problem of handling alignm...

The flattened, possibly co-rotating plane of satellite galaxies around Centaurus A, if more than a fortuitous alignment, adds to the pre-existing tension between well-studied Milky Way and M31 planes $\Lambda$CDM model structure formation. It was recently reported that A (CASP) may be rotationally supported, but further understanding system's kinematics is elusive in absence full three-dimensio...

Perspective Alignment is a novel method of solving backprojection, the well-known problem of computing threedimensional (3D) position and orientation (pose) of a model from two-dimensional (2D) image features. This paper demonstrates that previous back-projection methods can violate the visibility constraint by computing solution poses in which the model occludes features which should be visibl...
