Entanglement in SU(2)-invariant quantum systems: The positive partial transpose criterion and others [PDF]
Phys. Rev. A 72, 012307 (2005), 2005 We study entanglement in mixed bipartite quantum states which are invariant under simultaneous SU(2) transformations in both subsystems. Previous results on the behavior of such states under partial transposition are substantially extended. The spectrum of the partial transpose of a given SU(2)-invariant density matrix $\rho$ is entirely determined by ...

Transposing from the laboratory to the classroom to generate authentic research experiences for undergraduates. [PDF]
, 2013 Large lecture classes and standardized laboratory exercises are characteristic of introductory biology courses. Previous research has found that these courses do not adequately convey the process of scientific research and the excitement of discovery ...

, 2008 Genomic programs are yielding tremendous amounts of data about plant genomes and their expression. In order to exploit and understand this data it will be necessary to determine the mechanisms leading to natural variation of patterns of gene expression.

Heat-shock promoters: targets for evolution by P transposable elements in Drosophila. [PDF]
PLoS Genetics, 2006 Transposable elements are potent agents of genomic change during evolution, but require access to chromatin for insertion-and not all genes provide equivalent access.

Quantum states with strong positive partial transpose [PDF]
Phys. Rev. A 77, 022113 (2008), 2007 We construct a large class of bipartite M x N quantum states which defines a proper subset of states with positive partial transposes (PPT). Any state from this class is PPT but the positivity of its partial transposition is recognized with respect to canonical factorization of the original density operator.

Identification and frequency of transposable elements in Eucalyptus
Genetics and Molecular Biology, 2005 Transposable elements (TE) are major components of eukaryotic genomes and involved in cell regulation and organism evolution. We have analyzed 123,889 expressed sequence tags of the Eucalyptus Genome Project database and found 124 sequences representing ...

Insertion sequence inversions mediated by ectopic recombination between terminal inverted repeats. [PDF]
PLoS ONE, 2010 Transposable elements are widely distributed and diverse in both eukaryotes and prokaryotes, as exemplified by DNA transposons. As a result, they represent a considerable source of genomic variation, for example through ectopic (i.e.

The effects of recombination rate on the distribution and abundance of transposable elements [PDF]
, 2008 Transposable elements (TEs) often accumulate in regions of the genome with suppressed recombination. But it is unclear whether this pattern reflects a reduction in the efficacy of selection against deleterious insertions or a relaxation of ectopic ...

Nature Neuroscience, 2018 Transposable elements, known colloquially as ‘jumping genes’, constitute approximately 45% of the human genome. Cells utilize epigenetic defenses to limit transposable element jumping, including formation of silencing heterochromatin and generation of ...
