Gromov-Hausdorff Collapsing of Calabi-Yau manifolds
(International PressCommunications in Analysis and Geometry, 2016-06-08)This paper is a sequel to Collapsing of Abelian Fibered Calabi-Yau Manifolds [12]. We further study Gromov–Hausdorff collapsing limits of Ricci-flat Kähler metrics on abelian fibered Calabi–Yau manifolds. Firstly, we show ...

Simple Containers for Simple Hypergraphs
(Cambridge University PressCombinatorics Probability and Computing, 2016-05-01)We give an easy method for constructing containers for simple hypergraphs. The method also has consequences for non-simple hypergraphs. Some applications are given; in particular, a very transparent calculation is offered ...

Hypergraph containers
(SpringerInventiones Mathematicae, 2015-01-08)We develop a notion of containment for independent sets in hypergraphs. For every r-uniform hypergraph G, we find a relatively small collection C of vertex subsets, such that every independent set of G is contained within ...

Alpha Invariants and K-Stability for General Polarizations of Fano Varieties
(Oxford University PressINTERNATIONAL MATHEMATICS RESEARCH NOTICES, 2014-09-26)We provide a sufficient condition for polarisations of Fano varieties to be K-stable in terms of Tian’s alpha invariant, which uses the log canonical threshold to measure singularities of divisors in the linear system ...

Random Intersection Trees
(JMLRJournal of Machine Learning Research, 2014-02)Finding interactions between variables in large and high-dimensional datasets is often a serious computational challenge. Most approaches build up interaction sets incrementally, adding variables in a greedy fashion. The ...

Response to: DNA identification by pedigree likelihood ratio accommodating population substructure and mutations
(2011-03-25)Abstract Mutation models are important in many areas of genetics including forensics. This letter criticizes the model of the paper 'DNA identification by pedigree likelihood ratio accommodating population substructure and ...

Computational modeling of the EGFR network elucidates control mechanisms regulating signal dynamics
(2009-12-22)Abstract Background The epidermal growth factor receptor (EGFR) signaling pathway plays a key role in regulation of cellular growth and development. While highly studied, it is still not fully understood how the signal is ...

The Fourier transform for certain hyperKähler fourfolds
(American Mathematical SocietyThe Fourier transform for certain hyperKähler fourfolds, 2015-11-18)Using a codimension-1 algebraic cycle obtained from the Poincar e line bundle, Beauville de ned the Fourier transform on the Chow groups of an abelian variety A and showed that the Fourier transform induces a decomposition ...
