Ground-state properties of the two-site Hubbard-Holstein model: an exact solution
, 2008 We revisit the two-site Hubbard-Holstein model by using extended phonon coherent states. The nontrivial singlet bipolaron is studied exactly in the whole coupling regime.

NEST SITE FIDELITY OF PARAPHIDIPPUS AURANTIA (SALTICIDAE)
Journal of Arachnology, 2006 Abstract We investigated the nest building behavior of Paraphidippus aurantia (Lucas 1833) (Salticidae) following the experimental destruction of their nests. We located 61 nests on 52 pine saplings (43 saplings with one nest, nine with two nests) and carefully displaced all spiders and destroyed their nests.

Coordination of tRNA Synthetase Active Sites for Chemical Fidelity [PDF]
Journal of Biological Chemistry, 2012 Statistical proteomes that are naturally occurring can result from mechanisms involving aminoacyl-tRNA synthetases (aaRSs) with inactivated hydrolytic editing active sites. In one case, Mycoplasma mobile leucyl-tRNA synthetase (LeuRS) is uniquely missing its entire amino acid editing domain, called CP1, which is otherwise present in all known LeuRSs ...

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Opportunistic visitors: long-term behavioural response of bull sharks to food provisioning in Fiji. [PDF]
PLoS ONE, 2013 Shark-based tourism that uses bait to reliably attract certain species to specific sites so that divers can view them is a growing industry globally, but remains a controversial issue.

Molecular Oncology, EarlyView.A‐to‐I editing of miRNAs, particularly miR‐200b‐3p, contributes to HGSOC progression by enhancing cancer cell proliferation, migration and 3D growth. The edited form is linked to poorer patient survival and the identification of novel molecular targets.

Molecular Oncology, EarlyView.The cancer problem is increasing globally with projections up to the year 2050 showing unfavourable outcomes in terms of incidence and cancer‐related deaths. The main challenges are prevention, improved therapeutics resulting in increased cure rates and enhanced health‐related quality of life.

Ecology and Evolution, 2022 Environmental variables are often the primary drivers of species' distributions as they define their niche. However, individuals, or groups of individuals, may sometimes adopt a limited range within this larger suitable habitat as a result of social and ...

Fast Ground State Manipulation of Neutral Atoms in Microscopic Optical Traps
, 2005 We demonstrate Rabi flopping at MHz rates between ground hyperfine states of neutral $^{87}$Rb atoms that are trapped in two micron sized optical traps.
