The Structure of Preference Orders
2015Preferences are an important natural concept in real life and are well-known in the database and artificial intelligence community. Modeling preferences as strict partial orders closely matches people’s intuition. There are many algorithms for the evaluation of these strict partial orders.

Fuzzy ordered structures and fuzzy lattice ordered groups
Journal of Intelligent & Fuzzy Systems, 2014Fuzzy (lattice valued) posets are investigated with the order being a fuzzy relation on a fuzzy set. In this framework, fuzzy chains and generally fuzzy lattices are investigated. These are applied to fuzzy lattice ordered subgroups of lattice ordered groups.

Higher-Order Quadruplex Structures
2012Structural studies have shown that four G-tracts along a DNA strand are the minimal requirement for intramolecular G-quadruplex formation. Longer DNA sequences containing multiples of four G-tracts could, in principle, form higher-order structures based on multiple G-quadruplex blocks.

Is There Any Order in the Structure of Lignin?
Energy & Fuels, 1994The biopolymer lignin, an important constituent of terrestrial plants whine chemistry and reactivity are of great importance in many areas of energy research and industry, is thought to be biosynthesized through a random polymerization. Computer-assisted structure elucidation and molecular simulations presented in this report suggest that the ...

Abstract Superlattice is an ordered array of atoms that occur during their rearrangement from random site locations in the disordered solution to specific lattice sites in the ordered structure during phase transformation. This article provides a description of antiphase boundaries, their dislocations and degrees of ordering (long and ...

The Oxford Handbook of Linguistic Minimalism provides a complete assessment of the achievements and challenges of the Minimalist Program. Established fifteen years ago by Noam Chomsky, with the aim of making all statements about language as simple and general as possible, linguistic minimalism is now at the centre of efforts to understand how the human

Structural Tractability of ORDER BY Queries.
2013Existing structural tractability results for ORDER BY queries are extended to the general framework of tree projections, which encompasses all known polynomial-time decomposition methods, and to more general kinds of ranking criteria. Tractability results are also established for MAX (and MIN) queries, where one is interested just in the best answer ...
