Scalable Synthesis of Monolayer Hexagonal Boron Nitride on Graphene with Giant Bandgap Renormalization.

Monolayer hexagonal boron nitride (hBN) has been widely considered a fundamental building block for 2D heterostructures and devices. However, the controlled and scalable synthesis of hBN and its 2D heterostructures has remained a daunting challenge. Here, an hBN/graphene (hBN/G) interface-mediated growth process for the controlled synthesis of high-quality monolayer hBN is proposed and further demonstrated.

The Macroeconomic Imbalance Procedure at the Heart of EU Economic Governance Reform.

While the euro officially came into being in 1999, it was the introduction of euro notes and coins 20 years ago in January 2002 that made the common currency a tangible reality for European citizens. The circle of member states has since grown from 11 to 19, and a growing section of the population no longer has any personal experience with a "national" currency, yet the debate on the legal and institutional framework underpinning the common currency has never gone away.

Randomised Phase II Feasibility Trial of Image-guided External Beam Radiotherapy With or Without High Dose Rate Brachytherapy Boost in Men with Intermediate-risk Prostate Cancer (CCTG PR15/ NCT01982786).

Aims: We conducted a multicentre feasibility study to assess the ability to randomise patients between image-guided radiotherapy (IGRT) and IGRT + high dose rate (HDR) brachytherapy boost and to adhere to appropriate radiation quality assurance standards.

Materials And Methods: The primary end point was to determine the ability to randomise 60 patients over an 18 month period. Arm 1 (IGRT) patients received 78 Gy in 39 fractions or 60 Gy in 20 fractions (physician's preference), whereas arm 2 (IGRT + HDR) received 37.

Intraocular pressure and visual field decay in chronic glaucoma.

A total of 41 eyes of 28 patients with primary open-angle glaucoma and low-tension glaucoma (group 1) were followed for 12-72 months with tonometry and automated perimetry. A second group consisting of 13 eyes (9 patients) with secondary glaucoma (pigment dispersion, goniodysgenesis, ciliolenticular block and chronic angle closure) was followed for 13-60 months. None of the eyes had undergone filtering surgery during the follow-up period.
