Abstract Speech enhancement plays a crucial role in improving speech clarity and intelligibility in noisy environments, benefiting applications such as telecommunications, assistive hearing, voice-activated systems, and automatic speech recognition. Although transformer and conformer-based models achieve state-of-the-art performance, their complexity makes real-time deployment on resource-constrained devices impractical. In contrast, convolutional neural networks offer efficient on-device deployment due to their lower...

A depression in structural distortion to improve transparent ZnO electrodes by bismuth doping
Abstract Bi-doped ZnO thin films were deposited on glass substrates using radio frequency magnetron sputtering, with varying concentrations of impurities. The effect of Bi concentration on the structural, electrical, and optical properties of these films was investigated. This study indicates that a doping concentration of 1 at% Bi is optimal for enhancing the crystalline quality and photoelectric characteristics of the ZnO films. At this concentration, the films...
DYNAFormer: Enhancing transformer segmentation with dynamic anchor mask for medical imaging
Abstract Polyp shape is critical for diagnosing colorectal polyps and assessing cancer risk, yet there is limited data on segmenting pedunculated and sessile polyps. This paper introduces PolypDB_INS, a dataset of 4403 images containing 4918 annotated polyps, specifically for sessile and pedunculated polyps. In addition, we propose DYNAFormer, a novel transformer-based model utilizing an anchor...
Ab initio Kinetics of OH + Fulvenallene
Abstract This study presents a thorough kinetic mechanism of the OH-initiated reaction of fulvenallene (C7H6), a crucial intermediate in the formation of polycyclic aromatic hydrocarbons (PAHs), over a wide T and P range (T = 200 – 2000 K and P = 0.76 – 76,000 Torr), using different computational tools. The temperature- and pressure-dependent behaviors of the title system were investigated through...
