We report the demonstration of a second-order interference experiment by use of thermal light emitted from a warm atomic ensemble in two spatially separated unbalanced Michelson interferometers(UMIs).This novel multipath correlation interference with thermal light has been theoretically proposed by Tamma[New ***.18,032002(2016)].In our experiment,the bright thermal light used for second-order interference is superradiantly emitted via collective two-photon coherence in Doppler-broadened cascade-type 87 Rb *** to the long coherence time of the thermal light from the atomic ensemble,we observe its second-order interference in the two independent UMIs by means of time-resolved coincidence *** temporal waveforms of the interfering thermal light in the two spatially separated UMIs exhibit similarities with the temporal two-photon waveform of time–energy entangled photon pairs in Franson *** results can contribute toward a better understanding of the relation between first-and second-order interferences that are at the heart of photonics-based quantum information science.

In the next generation wireless communication systems operating at near terahertz frequencies, dielectric substrates with the lowest possible permittivity and loss factor are becoming essential. In this work, highly porous (98.9% ± 0.1%) and lightweight silica foams (0.025 ± 0.005 g/cm3), that have extremely low relative permittivity (εr = 1.018 ± 0.003 at 300 GHz) and corresponding loss factor (tan δ< 3 × 10−4 at 300 GHz) are synthetized by a template-assisted sol-gel method. After dip-coating the slabs of foams with a thin film of cellulose nanofibers, sufficiently smooth surfaces are obtained, on which it is convenient to deposit electrically conductive planar thin films of metals important for applications in electronics and telecommunication devices. Here, micropatterns of Ag thin films are sputtered on the substrates through a shadow mask to demonstrate double split-ring resonator metamaterial structures as radio frequency filters operating in the sub-THz band.

作者： Toshinungla Ao Jichule seb T. Ajungla Chitta Ranjan Deb Department of Botany Nagaland University Lumami India

The Indian sub-continent is blessed with favorable agro climatic conditions that are suitable to a varied range of fungal species. Though the occurrence of mushrooms is of diverse nature, they are not well studied and documented. Northeastern region of India is one of the biodiversity hotspots. Nagaland is one of the Northeastern states of India. The people of the state highly covet mushrooms and have been a delicacy since time immemorial. The present study documents the macro fungal diversity in various districts of the state. A total of 87 species of wild mushrooms were collected and identified. They are parasitic, saprophytic and ecto-mycorrhizal in habitat. The highest numbers of mushroom species were collected during May–September from the study areas. Of the collected mushrooms, 37 species were identified as edible, 21 species medicinal, 5 poisonous and 37 inedible/unclassified.

苹果ATT框架对广告营销行业而言,究竟意味着什么?它将在何种程度上对哪些关联方带来影响?靴子终于落地,经过数月的猜测和困惑,苹果备受期待的隐私保护行动于4月26日生效。虽然从理论上讲,为这一时刻所做的准备已经在幕后进行了一段时间,但市场似乎仍然对接下来发生的事情准备不足。关于ATT的几个基础问答ATT是什么?首先,我们有必要了解一下App Tracking Transparency(简称"ATT",苹果应用程序跟踪透明度)功能的相关知识。

02的这一场探索,为品牌在虚拟空间的延伸留下了无尽的"解码"想象。2020年4月24日,著名说唱歌手Travis Scott在《堡垒之夜》(Fortnite)游戏内举行了一场名为"Astronomical"的虚拟演唱会。一年多以来,这场音乐会激起的涟漪依然荡漾在世人的心间。事实上,这也正是O2体育馆(O2 Arena)的灵感之源,其运营人员将这场音乐会视为一个试金石:如果艺术家能够利用像《堡垒之夜》这样的平台将更宏大的世界展现在世人面前,那么所有参与其中的人都能从中获益。
