Optimization of Current Injection in AlGaInP Core−Shell Nanowire Light-Emitting Diodes

Core–shell nanowires offer great potential to enhance the efficiency of light-emitting diodes (LEDs) and expand the attainable wavelength range of LEDs over the whole visible spectrum. Additionally, nanowire (NW) LEDs can offer both improved light extraction and emission enhancement if the diameter of the wires is not larger than half the emission wavelength (λ/2). However, AlGaInP nanowire LEDs h

"The need and ability for expansion" : Conceptions of living space in the small-state geopolitics of Gudmund Hatt

Although they are often subjected to critical scrutiny, formal geopolitical practices have rarely been put on trial. One exception is the case of Gudmund Hatt (1884-1960), professor of human geography at Copenhagen University from 1929 to 1947, who was found guilty of “dishonorable national conduct” for his geopolitics during the German occupation. As a contribution to the critical history of geop

Over the past decades, a ‘neoclassical geopolitics’ has emerged in and beyond the field of International Relations. This diverse practice reproduces many of the problems that characterised classical geopolitics, notably an excessive tendency to explain politics on the basis of ostensibly permanent geographical factors. As a contribution to the interdisciplinary dialogue between International Relat

Global, regional, and national disability-adjusted life-years (DALYs) for 315 diseases and injuries and healthy life expectancy (HALE), 1990-2015 : a systematic analysis for the Global Burden of Disease Study 2015

BACKGROUND: Healthy life expectancy (HALE) and disability-adjusted life-years (DALYs) provide summary measures of health across geographies and time that can inform assessments of epidemiological patterns and health system performance, help to prioritise investments in research and development, and monitor progress toward the Sustainable Development Goals (SDGs). We aimed to provide updated HALE a
