We analyze 5108 AFGKM stars with at least five high precision radial velocity points as well Gaia and Hipparcos astrometric data utilizing a novel pipeline developed in previous work. find 914 signals periods longer than 1000\,d. Around these signals, 167 cold giants 68 other types of companions are identified by combined analyses velocity, astrometry, imaging data. Without correcting for detec...

Abstract. The main advantage of inverse iteration over the QR algorithm and Divide & Conquer for the symmetric tridiagonal eigenproblem is that subsets of eigenpairs can be computed at reduced cost. The MRRR algorithm (MRRR = Multiple Relatively Robust Representations) is a clever variant of inverse iteration without the need for reorthogonalization. stegr, the current version of MRRR in LAPACK...

In this study, we attempt to understand and explain positional selection pressure in terms of underlying Abstract physical and chemical properties. We propose a set of constraining assumptions about how these pressures behave, then describe a procedure for analysing and explaining the distribution of residues at a particular position in a multiple sequence alignment. In contrast to previous app...
