Efficient speech denoising using CleanUNet optimized with Mamba and hybrid spectral loss
Abstract Speech enhancement aims to recover clean speech from signals degraded by noise and adverse acoustic conditions, such as background interference and echo. CleanUNet has emerged as an effective solution for causal speech denoising, but its high computational demands limit...

Low-Order Bessel-Type PID Dynamics in Lithium-Based Tritium Breeding and Heat Removal Systems
Lithium plays a dual role in deuterium-tritium (D-T) fusion systems by enabling tritium breeding in blankets and providing an efficient heat removal medium in liquid-metal components. However, most existing investigations treat neutronic behavior, jet thermohydraulics, and feedba...

Autotie: A partial automation of the seismic to well tie with matching region estimation
Abstract Tying seismic data to well logs is a critical step in seismic amplitude processing and interpretation. This process is often repeated throughout the exploration phase to enhance the understanding of well characteristics, such as the time-depth relationship. However, the...
