Recovering a phylogenetic tree using pairwise closure operations
A fundamental task in evolutionary biology is the amalgamation of a collection P of leaf-labelled trees into a single parent tree. A desirable feature of any such amalgamation is ...

Efficient Algorithms to Explore Conformation Spaces of Flexible Protein Loops
Two efficient and complementary sampling algorithms are presented to explore the space of closed clash-free conformations of a flexible protein loop. The "seed sampling" ...

Real algebraic numbers and polynomial systems of small degree
We present exact and complete algorithms based on precomputed Sturm-Habicht sequences, discriminants and invariants, that classify, isolate with rational points and compare the re...

Performance of Space-Time Codes: Gallager Bounds and Weight Enumeration
Since the standard union bound for space-time codes may diverge in quasi-static fading channels, the limit-before-average technique has been exploited to derive tight performance b...

Parametrization of approximate algebraic surfaces by lines
In this paper we present an algorithm for parametrizing approximate algebraic surfaces by lines. The algorithm is applicable to -irreducible algebraic surfaces of degree d having ...
