What is behind the meta-learning initialization of adaptive filter? - A naive method for accelerating convergence of adaptive multichannel active noise control.

Active noise control (ANC) is a typical signal-processing technique that has recently been utilized extensively to combat the urban noise problem. Although numerous advanced adaptive algorithms have been devised to enhance noise reduction performance, few of them have been implemented in actual ANC products due to their high computational complexity and slow convergence. With the rapid development of deep learning technology, Meta-learning-based initialization appears to become an efficient and cost-effective method for accelerating the convergence of adaptive algorithms.

What drives the decrease of glacier surface albedo in High Mountain Asia in the past two decades?

Glacier surface albedo is an important factor affecting glacier ablation, and a positive feedback mechanism has been observed between the surface albedo and mass balance of glaciers. It is important to understand the driving factors and mechanisms of glacier albedo changes (GAC). Based on the MODIS (Moderate resolution imaging spectroradiometer)-derived MOD10A1 and MYD10A1 albedo products, the glacier albedo trends in each MODIS grid cell during each melt season in High-Mountains Asia (HMA) from 2000 to 2020 were calculated.

Analysis of thermal decomposition of acidified sediments in gold plants and harmless disposal of it.

In the present work, thermal decomposition of ASs in air was characterized by a combination of TG-DSC, XRD, and TG-FTIR. The treatment of generated toxic (CN) gas was investigated as well. The result showed that the decomposition of ZnFe(CN) in ASs preferentially reacted with CuSCN leading to the early decomposition of ASs, in which a part of CuSCN decomposed into CuFeS or CuS followed by being oxidized to sulfates and oxides as the temperature increased to 420 °C.

Peptidomics analysis revealed that a novel peptide VMP‑19 protects against Ang II‑induced injury in human umbilical vein endothelial cells.

Vascular endothelial dysfunction is a vital pathological change in hypertension, which is mainly caused by apoptosis and oxidative stress injury of vascular endothelial cells. Peptidomics is a method for the direct analysis of small bioactive peptides in various biological samples using liquid chromatography‑mass spectrometry (MS)/MS. Given the advantages of the low molecular weight, optimum targeting and easy access to cells, peptides have attracted extensive attention in the field of drug research.

Synthesis and photocatalytic degradation ability evaluation for rhodamine B of ZnO@SiO composite with flower-like structure.

ZnO@SiO composite with flower-like structure was successfully prepared with molar ratio of ZnO/SiO = 1:1 based on the optimized synthesizing parameters of spherical SiO and flower-like ZnO. SiO particles were coated on the flower-like ZnO to form a homogeneous film through the multidimensional polycondensation of Si(OH). The photocatalytic degradation ability of ZnO@SiO composite for rhodamine B (RhB) obtained at different ZnO/SiO molar ratio and the comparison to that of flower-like ZnO showed that ZnO@SiO composite with ZnO/SiO molar ratio of 1:1 displayed a relatively good photocatalytic degradation ability to degrade RhB, but it was weaker than that of flower-like ZnO.
