The amplitude of self-oscillating mechanical resonators in cavity optomechanical systems is typically limited by nonlinearities arising from the cavity’s finite optical bandwidth. We propose and demonstrate a feedback technique for increasing this

The most common image of world politics involves states negotiating, cooperating, or sometimes fighting with one another; billiard balls in motion on a global pool table. Yet working through local proxies or agents, through what Eli Berman and David

The Great Recession and its aftershocks, including the Eurozone banking and debt crisis, add up to the worst global economic crisis since the Great Depression of the 1930s. Although economic explanations for the Great Recession have proliferated, the
We rely on NGOs to monitor the ethical practices of governments and for-profit firms and to undertake many humanitarian tasks that public and private actors will not do. While we are critical of public and private sector failures, we do not reflect e

The use of cavity optomechanics for optical information processing is hindered by mechanical dissipation and the difficulties in stored signal control. Here, the authors improve performances on both fronts using time-varying parametric feedback throu

Efficient switching and routing of photons of different wavelengths is desirable for future quantum information applications. To this end the authors demonstrate interference in a multimode system between two optomechanically induced transparency pro

International relations are generally understood as a realm of anarchy in which countries lack any superior authority and interact within a Hobbesian state of nature. In Hierarchy in International Relations, David A. Lake challenges this traditional

Abstract Background Background parenchymal uptake (BPU), which refers to the level of Tc-99m sestamibi uptake within normal fibroglandular tissue on molecular breast imaging (MBI), has been identified as a breast cancer risk factor, independent of ma

Why do states delegate certain tasks and responsibilities to international organizations rather than acting unilaterally or cooperating directly? Furthermore, to what extent do states continue to control IOs once authority has been delegated? Examini

Nanophotonic structures in single–crystal diamond (SCD) that simultaneously confine and co-localize photons and phonons are highly desirable for applications in quantum information science and optomechanics. Here we describe an optimized process
