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...

DPASV detection of metribuzin using the cathodic pretreated boron-doped diamond electrode
Abstract The widespread use of the triazinone herbicide metribuzin (MTZ) demands reliable, rapid, and cost-effective analytical methods for environmental monitoring. In this work, we report, for the first time, the electroanalytical determination of MTZ based on its anodic behavi...

Exploring the Vertical Ocean: A Comparative Review of Behavioral Strategies Across Marine Predators
The ocean is a vertically structured environment in which physical and biological conditions change dramatically with depth, yet the exploitation of this three-dimensional habitat by marine predators has largely been investigated within isolated taxonomic groups rather than throu...

Quantum Walk Dictionary Learning for Classical Image Representation: A Hybrid Framework
Abstract Quantum computing offers novel paradigms for data representation and signal processing, yet traditional Quantum Image Representation (QIP) models often face significant challenges regarding qubit resources and state preparation complexity. This paper introduces a hybrid...
