Transversal Spurious Mode Suppression in Ultra-Large-Coupling SH0 Acoustic Resonators on YX36 degrees-Cut Lithium Niobate

Luis Guillermo Villanueva Torrijo, Silvan Stettler

This work reports on the design and fabrication of fundamental shear horizontal (SH0) mode acoustic resonators based on a suspended lithium niobate (LNO) film at 1.04 GHz. Due to the large e16 piezoelectric coefficient of YX36 degrees.-cut LNO, fabricated ...

Global Auto-regressive Depth Recovery via Iterative Non-local Filtering

Pascal Frossard, Jingyu Yang, Xinchen Ye

Existing depth sensing techniques have many shortcomings in terms of resolution, completeness, and accuracy. The performance of 3-D broadcasting systems is therefore limited by the challenges of capturing high-resolution depth data. In this paper, we prese ...

Metamorphosis of cycloalkenes for the divergent total synthesis of polycyclic indole alkaloids

Qian Wang, Zhengren Xu, Jieping Zhu

From tryptamine and secologanine, nature generates monoterpene indole alkaloids with an unprecedented level of skeletal diversity through a ‘couple–divert’ sequence. Intrigued by this biosynthetic machinery, new strategies and tactics to access skeletally ...

Primary Voltage Control in Active Distribution Networks via Broadcast Signals: The Case of Distributed Storage

Jean-Yves Le Boudec, Mario Paolone, Dan-Cristian Tomozei, Konstantina Christakou, Maryam Bahramipanah

In this paper, we consider an active distribution network (ADN) that performs primary voltage control using real-time demand response via a broadcast low-rate communication signal. The ADN also owns distributed electrical energy storage. We show that it is ...
