Abstract

In speech enhancement, the lack of clear structural characteristics in the target speech phase requires the use of conservative and cumbersome network frameworks. It seems difficult to achieve competitive performance using direct methods and simple network architectures. However, we propose the MFNet, a direct and simple network that can not only map speech but also map reverse noise. This network is constructed by stacking global local former blocks (GLFBs), which combine the advantages of Mobileblock for global processing and Metaformer architecture for local interaction. Our experimental results demonstrate that our network using mapping method outperforms masking methods, and direct mapping of reverse noise is the optimal solution in strong noise environments. In a horizontal comparison on the 2020 Deep Noise Suppression (DNS) challenge test set without reverberation, to the best of our knowledge, MFNet is the current state-of-the-art (SOTA) mapping model.

21. Combined treatment of phonon scattering by electrons and point defects explains the thermal conductivity reduction in highly-doped Si

Abstract

The mechanisms causing the reduction in lattice thermal conductivity in highly P- and B-doped Si are looked into in detail. Scattering rates of phonons by point defects, as well as by electrons, are calculated from first principles. Lattice thermal conductivities are calculated considering these scattering mechanisms both individually and together. It is found that at low carrier concentrations and temperatures phonon scattering by electrons is dominant and can reproduce the experimental thermal conductivity reduction. However, at higher doping concentrations the scattering rates of phonons by point defects dominate the ones by electrons except for the lowest phonon frequencies. Consequently, phonon scattering by point defects contributes substantially to the thermal conductivity reduction in Si at defect concentrations above $10^{19}$ cm$^{-3}$ even at room temperature. Only when, phonon scattering by both point defects and electrons are taken into account, excellent agreement is obtained with the experimental values at all temperatures., Comment: 7 pages, 5 figures

Abstract

Diabetic foot is one of the most severe complications of diabetes. It is caused by high blood sugar, resulting in combined neuropathy and various degrees of peripheral vascular disease, leading to local microcirculation disorders. This condition can trigger infections, ulcers, and deep tissue damage in the lower limbs. In severe cases, gangrene may occur, leading to amputation. Therefore, timely microcirculation monitoring of the feet in diabetic patients can help detect early blood supply issues. Prompt and effective intervention and treatment for diabetic patients with microcirculation disorders in the feet can prevent the occurrence and development of diabetic foot. Physical factor therapy utilizes various forms of physical energy to induce reactions in the body, such as dilating blood vessels, increasing blood flow, and promoting tissue blood supply. Simultaneously, it stimulates nerves and muscles, aiding in improving nerve conduction and promoting nerve regeneration. This helps prevent and improve microcirculation disorders in diabetic feet. This article outlines the microcirculation disorders in diabetic feet, along with monitoring and treatment methods. It focuses on the principles and efficacy of common physical factor methods for microcirculation intervention, as well as research advancements in their clinical application for diabetic foot. This information serves as a reference for the treatment and adjunctive research of diabetic foot.
