When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording the diffraction patterns formed by shining a laser beam through it. At the ...

Making a perfect lens that produces flawless images has been a dream of lens makers for centuries. In 1873, Ernst Abbe discovered a fundamental 'diffraction limit' in optics: whenever an object is ...
The Chinese central authorities have introduced a guiding document that rolls out a series of specific provisions and targeted measures to crack down on formalism and reduce the burden on ...
Consistent efforts have been made by the Communist Party of China in the past five years to solve problems arising from the practice of formalities for formalities' sake to avoid placing unnecessary ...
Abstract: In this paper we introduce a novel framework for expressing and learning force-sensitive robot manipulation skills. It is based on a formalism that extends our previous work on adaptive ...

Abstract: We derive a new asymptotic procedure for the analysis of scalar wave diffraction by semi-infinite circular cones and apply it to derive a new closed-form expression for the tip-diffracted ...
The fresh Pt 1 /TiO 2 was first characterized by X-ray diffraction and high-resolution transmission electron microscopy (SI Appendix, Figs. S1–S3). The results showed that the characteristic peaks ...
