UN FORUM SERIES – measuring progress on human rights, and peace, in conflict affected areas

This post was contributed by Andrea Iff, Head of Business and Peace, swisspeace. Conflict-affected and high-risk areas are characterized by specific political, economic and social conditions. An area can be conflict-affected either because of a violent conflict that exists between language, religious or identity groups independently from a business operation or because of a violent conflict between a company and a community surrounding a business operation

GigaRad – a multi-purpose high-resolution ground-based radar system

Recently DLR has developed and constructed a new experimental radar instrument for various applications like radar signature collection, SAR/ISAR imaging, motion detection, tracking, etc., where high performance and high flexibility have been the key drivers for system design. Consequently a multi-purpose and multi-channel radar called GigaRad is operated in X band and allows an overall bandwidth of up to 6 GHz, resulting in a theoretical range resolution of up to 2.5 cm. Hence, primary obligation is a detailed analysis of various possible error sources, being of no or less relevance for low-resolution systems. A high degree of digital technology enables advanced signal processing and error correction to be applied. The paper outlines technical main features of the radar, the basic error correction strategy and illustrates some first imaging results

A preliminary study of DNA damage in peripheral lymphocytes from lung cancer patients and healthy subjects

A pilot study was undertaken to investigate the differences in oxidative DNA damage and 2-h DNA repair in peripheral lymphocytes between lung cancer patients and healthy subjects. Twenty-four lung cancer patients and 23 normal controls were recruited from the Queen Mary Hospital, Hong Kong SAR, China. Single cell gel electrophoresis (comet assay) was performed to measure the oxidative damage, repair and baseline of peripheral lymphocytes in the subjects. There were no significant differences in baseline DNA damage and oxidative stress damage and DNA repair at 2 h among the two groups of lung cancer patients who had blood taken before and those who had blood taken after chemotherapy, and normal subjects. There were no differences in basal DNA, oxidative DNA damage or DNA repair between those with and without vitamin supplements in normal subject diets. Our results demonstrated that oxidative DNA damage in lymphocytes is not associated with the risk of lung cancer.published_or_final_versio

Spontaneous emission enhancement in strain-induced WSe2 monolayer based quantum light sources on metallic surfaces

Atomic monolayers of transition metal dichalcogenides represent an emerging material platform for the implementation of ultra compact quantum light emitters via strain engineering. In this framework, we discuss experimental results on creation of strain induced single photon sources using a WSe2 monolayer on a silver substrate, coated with a very thin dielectric layer. We identify quantum emitters which are formed at various locations in the sample. The emission is highly linearly polarized, stable in linewidth and decay times down to 300 ps are observed. We provide numerical calculations of our monolayer-metal device platform to assess the strength of the radiative decay rate enhancement by the presence of the plasmonic structure. We believe, that our results represent a crucial step towards the ultra-compact integration of high performance single photon sources in nanoplasmonic devices and circuits
