Optimising repeater schemes for the quantum internet [PDF]
Phys. Rev. A 103, 032610 (2021), 2020 The rate at which quantum communication tasks can be performed using direct transmission is fundamentally hindered by the channel loss. Quantum repeaters allow, in principle, to overcome these limitations, but their introduction necessarily adds an additional layer of complexity to the distribution of entanglement.

The CAG trinucleotide repeat length in the androgen receptor does not predict the early onset of prostate cancer [PDF]
, 2002 Objective To relate the repeat length of the androgen-receptor CAG trinucleotide to the age of onset of prostate cancer, stage and grade of disease. Patients and methods After obtaining ethical approval, 265 patients with locally confined or locally ...

Somatic and germinal recombination of a direct repeat in Arabidopsis. [PDF]
Genetics, 1992 Abstract Homologous recombination between a pair of directly repeated transgenes was studied in Arabidopsis. The test construct included two different internal, non-overlapping deletion alleles of npt (neomycin phosphotransferase) flanking an active HPT (hygromycin phosphotransferase) gene.

Evolution and control of imprinted FWA genes in the genus Arabidopsis. [PDF]
PLoS Genetics, 2008 A central question in genomic imprinting is how a specific sequence is recognized as the target for epigenetic marking. In both mammals and plants, imprinted genes are often associated with tandem repeats and transposon-related sequences, but the role of

Targeted Derepression of the Human Immunodeficiency Virus Type 1 Long Terminal Repeat by Pyrrole-Imidazole Polyamides [PDF]
, 2002 The host factor LSF represses the human immunodeficiency virus type 1 long terminal repeat (LTR) by mediating recruitment of histone deacetylase. We show that pyrrole-imidazole polyamides targeted to the LTR can specifically block LSF binding both in ...

Repetitive DNA profile of the amphibian mitogenome
BMC Bioinformatics, 2020 Background Repetitive DNA elements such as direct and inverted repeat sequences are present in every genome, playing numerous biological roles. In amphibians, the functions and effects of the repeat sequences have not been extensively explored.

A common trinucleotide repeat expansion within the transcription factor 4 (TCF4, E2-2) gene predicts Fuchs corneal dystrophy. [PDF]
PLoS ONE, 2012 Fuchs endothelial corneal dystrophy (FECD) is a common, familial disease of the corneal endothelium and is the leading indication for corneal transplantation.
