Open AccessExome sequencing-driven discovery of coding polymorphisms associated with common metabolic phenotypes
Human complex metabolic traits are in part regulated by genetic determinants. Here we applied exome sequencing to identify novel associations of coding polymorphisms at minor allele frequencies (MAFs) >1% with...

Electric-field-induced coherent coupling of the exciton states in a single quantum dot
The ability to generate entangled photon pairs from a quantum dot critically depends on the size of the fine-structure splitting of its exciton states. A demonstration of the ability to tune this splitting wit...

A High Efficiency, Purcell-enhanced Microcavity Single Photon Emitting Diode
Efficient, high-frequency quantum light sources are a prerequisite for advanced quantum information processing. Here, we report the observation of a Purcell enhancement in the radiative decay rate of a single ...

Interference of dissimilar photon sources
When two identical photons hit a half-silvered mirror, quantum mechanics requires that both pass through or both be reflected in the same direction. Previously, this effect had only been demonstrated with phot...

Association of variants in the fat mass and obesity associated (FTO) gene with polycystic ovary syndrome
Variants in the fat-mass and obesity-associated gene (FTO) influence susceptibility to type 2 diabetes via an effect on adiposity/obesity. Given the important role of obesity in the aetiology of both polycystic o...

No evidence that established type 2 diabetes susceptibility variants in the PPARG and KCNJ11 genes have pleiotropic effects on early growth
The P12A variant in the PPARG gene and the E23K polymorphism in KCNJ11 are both known to influence individual predisposition to type 2 diabetes. If the effect of these variants on insulin secretion and action wer...

Disparate genetic influences on polycystic ovary syndrome (PCOS) and type 2 diabetes revealed by a lack of association between common variants within the TCF7L2 gene and PCOS
Common variants of the gene encoding transcription factor 7-like 2 (TCF7L2) have a powerful effect on individual risk of type 2 diabetes (per allele odds ratio ∼1.35). Polycystic ovary syndrome (PCOS) and type 2 ...

Bilateral congenital diaphragmatic hernia
Bilateral congenital diaphragmatic hernia (CDH) is a rare condition, with the literature suggesting a bleak prognosis. We describe a case of bilateral CDH that, despite confirming the challenges of diagnosis, ...

Photo-pumped lasing from low density self-assembled InGaAs/GaAs quantum dots within a high-Q vertical cavity
A high-Q cavity containing three layers of self-assembled InGaAs/GaAs quantum dots has been prepared. Emission occurs in the wavelength range 1275–1285 nm over the wafer surface. We have observed lasing threshold...

Carrier recombination in InAs/GaAs Quantum Dot and GaInNAs/GaAs Quantum Well LEDs emitting near 1300 nm.
We have studied the emission from LEDs based on GaInNAs Quantum Wells (QWs) and InAs Quantum Dots (QDs) as a function of temperature and current. It is found that the carrier loss in GaInNAs QWs is dominated b...
