Advanced Optical Materials, EarlyView.One of the high‐impact research goals in neuromorphic photonics is to build scalable photonic artificial intelligence computing at high energy efficiency. This perspective paper discusses microring resonator (MRR)‐based large‐scale photonic neural networks, variations of MRR resonance wavelength from fabrication, and post‐fabrication processing with ...

Yield estimation of summer maize based on multi‐source remote‐sensing data
Agronomy Journal, Volume 114, Issue 6, Page 3389-3406, November/December 2022., 2022 Abstract Accurately estimating regional‐scale crop yields is substantial in determining current agricultural production performance and effective agricultural land management. The Yuncheng Basin is an important grain‐producing area in the Shanxi Province. This paper used Sentinel 2A with a spatial resolution of 10 m and MODIS with a temporal resolution

Enhancing the Efficiency of Polariton OLEDs in and Beyond the Single‐Excitation Subspace
Advanced Optical Materials, EarlyView.Organic light‐emitting diodes (OLEDs) are transforming lighting with eco‐friendly manufacturing and flexible applications. However, since 75 % of excited states (triplets) are non‐emissive, recent research has focused on triplet harvesting. This work proposes a predictive polariton‐based model, exploring conditions for OLED enhancement and showing that

Telaah Ayat-Ayat Hisab Rukyah Perspektif Astronomi
Al-Mizan, 2018 The discourse of the verses of the Qur’an regarding the reckoning (hisab) and determining date by sighting of moon (rukyat) did not find passages that describe implicitly on an initial determination by using the lunar month of reckoning, but explicitly ...

Advanced Optical Materials, EarlyView.Picosecond spin current pulses generated by ferrimagnetic GdCo are studied via THz emission spectroscopy. Due to the GdCo micromagnetic structure, the spin current vanishes at compensation when a magnetic field is applied but persists for zero field. At room temperature, the THz spin current is dominated by Co. At low temperatures, Gd can significantly

Parameterized Two‐Qubit Gates for Enhanced Variational Quantum Eigensolver
Annalen der Physik, Volume 534, Issue 12, December 2022., 2022 The parameterized quantum circuit used in variational quantum algorithms usually consists of parameterized single‐qubit gates and fixed entangling multi‐qubit gates. Here, it is considered what happens when the entangling gates become parameterized, which allows for directly tuning the entangling power of the circuit. The parameterized entangling gates
