Sv-rings and Sv-porings
SV-rings are commutative rings whose factor rings modulo prime ideals are valuation rings. SV-rings occur most naturally in connection with partially ordered rings (= porings) and have been studied only in this context so far. The present note first develops the theory of SV-rings systematically, without assuming the presence of a partial order. Particular attention is paid to the question of a...
متن کاملDune-Yardang Interactions in Becquerel Crater, Mars.
Isolated landscapes largely shaped by aeolian processes can occur on Earth, while the majority of Mars' recent history has been dominated by wind-driven activity. Resultantly, Martian landscapes often exhibit large-scale aeolian features, including yardang landforms carved from sedimentary-layered deposits. High-resolution orbital monitoring has revealed that persistent bedform activity is occu...
متن کاملAllelic Complementation Between MHC Haplotypes BQ and B17ËIncreases Regression o
Major histocompatibility (B) complex haplotypes BQ and B17 were examined for their effect on Rous sarcoma outcome. Pedigree matings of BQB17 chickens from the second backcross generation (BC2) of Line UCD 001 (BQBQ) mated to Line UCD 003 (B17B17) produced progeny with genotypes BQBQ, BQB17, and B17B17. Sixweek-old chickens were injected with subgroup A Rous sarcoma virus (RSV). The tumors were ...
متن کاملPreference Queries with SV-Semantics
Personalization of database queries requires a semantically rich, easy to handle and flexible preference model. Building on preferences as strict partial orders we provide a variety of intuitive base preference constructors for numerical and categorical data, including so-called d-parameters. As a novel semantic concept for complex preferences we introduce the notion of ‘substitutable values’ (...
