Low-loss photonic integrated circuits (PIC) and microresonators have enabled novel applications ranging from narrow-linewidth lasers, microwave photonics, to chip-scale optical frequency combs quantum conversion. To translate these results into a widespread technology, attaining ultralow losses with established foundry manufacturing is critical. Recent advances in fabrication of Si3N4 photonics shown that ultralow-loss, dispersion-engineered can be attained at die-level throughput. For...
Direct cross-coupling between simple arenes and heterocyclic amines under mild conditions is undoubtedly important for C-N bonds construction. Selective C(sp2)-H amination more valuable. Herein we show a selective of (alkyl-substituted benzenes, biphenyl anisole derivatives) accompanied by hydrogen evolution using azoles as nitrogen sources. The reaction bonds, providing route to N-arylazoles. KIE (kinetic isotope effect) experiment reveals the cleavage C-H bond not involved in...

The availability of effective antiretroviral therapy has made HIV manageable, provided patients have consistent access to routine viral load (VL) testing. Nonetheless, frequent VL testing remains limited. There is a need for accessible, user-friendly systems that allow people living with (PLHIV) monitor their more frequently and empower self-management. Here, we developed ViraLite, sample-to-answer, compact, battery-powered system monitoring. built upon probe-based RT-LAMP assay allows...

Silicon nitride has emerged as a prominent platform for building photonics integrated circuits. While its nonlinear properties based on third-order effects have been successfully exploited, an efficient second harmonic generation in standard stoichiometric silicon (Si3N4) waveguides can also be achieved after all-optical poling, was recently shown. The root of such phenomenon attributed to the inscription self-organized periodic space-charge grating along waveguide, allowing effective χ(2)...
An accurate ego-motion estimation solution is vital for autonomous vehicles. LiDAR widely adopted in self-driving systems to obtain depth information directly and eliminate the influence of changing illumination environment.

Vision-based sensors such as LiDAR (Light Detection and Ranging) are adopted in the SLAM (Simultaneous Localization Mapping) system. In 16-beam aided system, due to difficulty of object detection by sparse laser data, neither grid-based nor feature point-based solution can avoid interference moving objects. an urban environment, pole-like objects common, invariant have distinguishing characteristics. Therefore, it is suitable bring more robust reliable positioning results auxiliary...
Indoor positioning is an important part of supporting the Internet Things and location-based services. Crowdsourcing-based magnetic map construction a key technology to realize wide-area consumer indoor positioning.
