This paper presents the design and simulation analysis of a tunable optical integrator based on ZnS-SiO2/Ge2Sb2Te5 superlattice (GST-SL) phase change material (PCM). The transfer function of the integrator is realized through a silicon microring resonator cladded with a three-layer GST-SL (GST-SL3-MRR). The integration of the PCM into the microring resonator enables a reconfigurable Q-factor, allowing for tunable integration orders between 0.5th and 1st. Through laser-induced phase transitions between amorphous and crystalline states, the transmission spectrum of the MRR can be dynamically adjusted. Simulation results show that the integration time window reaches 300 ps for the first-order integration, and the tunable integration results closely align with the ideal mathematical predictions. demonstrating the device's highly tunable performance. Further simulations of applications for quickly solving ordinary differential equations highlight the potential applications of our device in areas such as optical signal processing and image recognition. © 2025 SPIE.

This study aims to assess the mechanical properties and damping characteristics of polyester composites reinforced with flax and kenaf fibers, incorporating 5 wt.% each of rice husk and wood dust. The research will employ mechanical testing, dynamic mechanical analysis across various temperatures and frequencies, and Scanning Electron Microscopy (SEM). Experiments will measure tensile strength, flexural strength, impact strength, hardness, natural frequency, and damping coefficient (tan δ). SEM imaging will examine the fractured surfaces of tensile samples. Composites will be fabricated using a manual layup technique, combining mat fiber with 5 wt.% each of rice husk and wood dust. Initial findings suggest that fiber incorporation decreases damping curves (tan δ), while the addition of rice husk and wood dust positively correlates with the composite's natural frequency and damping factor. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.

Nowadays, batch normalization (BN) has become the core component of deep learning. Thanks to the advantage of stable training, an image super-resolution reconstruction model, enhanced super-resolution generative adversarial networks (ESRGAN), and an image super-resolution reconstruction algorithm use BN to help its stable training. However, BN normalizes different types of information. This causes artifacts in the generated super-resolution image. Based on this, the generator of ESRGAN removes BN and the discriminator retains BN. However, BN in the discriminator will also normalize the information of different images, thus affecting the discriminator judgment. Motivated by this, we replace BN in the discriminator with layer normalization (LN), instance normalization (IN), group normalization (GN), and representative batch normalization (RBN) without adding any normalization operation. After a large number of experiments, ESRGAN reaches the state of the art when GN (PSNR:27.72, SSIM:0.8316) is used in the discriminator on the Set5 dataset. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

This paper presents a reconfigurable matrix operations for optical digital computing using microring resonator (MMR) array assisted by ZnS-SiO2/Ge2Sb2Te5 superlattice (GST-SL) phase-change material (PCM). By overlaying the GST-SL onto the MMR array, the resonant state of each MMR element can be adjusted according to the assigned matrix weights, thereby modifying the optical matrix transfer function to yield specific logical operations. This device combines both nonlinear and linear operations to achieve the building blocks, including logic minterms and maxterms, for complex logic functions. Based on the basic logic units, combinational logic functions such as full addition and full subtraction have been numerically demonstrated. Our nanostructure reduces computational complexity and provides a basis for future array expansion, offering a promising new approach for integrated optical computing and optical signal processing. © 2025 SPIE.
