TL;DR: SNSPDs embedded in nanophotonic integrated circuits which achieve internal quantum efficiencies close to unity at 1550 nm wavelength allows for the SNSPDs to be operated at bias currents far below the critical current where unwanted dark count events reach milli-Hz levels while on-chip detection efficiencies above 70% are maintained.
Abstract: Superconducting nanowire single-photon detectors (SNSPDs) provide high efficiency for detecting individual photons while keeping dark counts and timing jitter minimal. Besides superior detection performance over a broad optical bandwidth, compatibility with an integrated optical platform is a crucial requirement for applications in emerging quantum photonic technologies. Here we present SNSPDs embedded in nanophotonic integrated circuits which achieve internal quantum efficiencies close to unity at 1550 nm wavelength. This allows for the SNSPDs to be operated at bias currents far below the critical current where unwanted dark count events reach milli-Hz levels while on-chip detection efficiencies above 70% are maintained. The measured dark count rates correspond to noise-equivalent powers in the 10−19 W/Hz−1/2 range and the timing jitter is as low as 35 ps. Our detectors are fully scalable and interface directly with waveguide-based optical platforms.

TL;DR: Based on a deductive, culturally decentered approach, new items were generated to improve the reliability of the original Social Axioms Survey, which measures individuals' general beliefs about the world as mentioned in this paper.
Abstract: Based on a deductive, culturally decentered approach, new items were generated to improve the reliability of the original Social Axioms Survey, which measures individuals' general beliefs about the world. In Study 1, results from 11 countries support the original five-factor structure and achieve higher reliability for the axiom dimensions as measured by the new scale. Moreover, moderate but meaningful associations between axiom and Big-Five personality dimensions were found. Temporal change of social axioms at the culture level was examined and found to be moderate. In Study 2, additional new items were generated for social complexity and fate control, then assessed in Hong Kong and the United States. Reliability was further improved for both dimensions. Additionally, two subfactors of fate control were identified: fate determinism and fate alterability. Fate determinism, but not fate alterability, related positively to neuroticism. Other relationships between axiom and personality dimensions were similar to those reported in Study 1. The short forms of the axiom dimensions were generally reliable and correlated highly with the long forms. This research thus provides a stronger foundation for applying the construct of social axioms around the world.

TL;DR: In this paper, structural transformation and its implications for productivity growth in the BRIC countries (Brazil, Russia, India, and China) from the 1980s onwards are studied, based on a critical assessment of the reliability and consistency of various primary data sources, which brings together a new database that provides trends in value added and employment at a detailed 35-sector level.

TL;DR: In this paper, the authors classify del Pezzo surfaces with quotient singularities and Picard rank one which admit a ℚ-Gorenstein smoothing as singular fibres.
Abstract: We classify del Pezzo surfaces with quotient singularities and Picard rank one which admit a ℚ-Gorenstein smoothing. These surfaces arise as singular fibres of del Pezzo fibrations in the 3-fold minimal model program and also in moduli problems.
