The world faces Covid-19 waves, and the overall pattern of confirmed cases shows periodic oscillations. In this paper, we investigate the spatiotemporal spread of Covid-19 in the network-organized SIR model with an extrinsic incubation period of the

Mechanical solitons are notoriously difficult to control. Here, the authors report a theoretical framework for programming static periodic topological solitons into a metamaterial, and demonstrate its implementation in real metamaterials computationa

In this article, a simple and effective approach is presented to reduce the Radar Cross Section (RCS) of microstrip patch antenna in ultra broad frequency band. This approach substitutes a metallic ground plane of a conventional patch antenna with a

Esculentoside A (EsA) is a saponin isolated from the roots of Phytolacca esculenta. Previous experiments have shown that it has strong antiinflammatory effects. To investigate the mechanism of anti-inflammatory effects of esculentoside A (EsA),[3H] a

Esculentoside A (EsA) is a saponin isolated from the roots of Phytolacca esculenta. Previous experiments have shown that it has strong anti-inflammatory effects. Tumour necrosis factor (TNF) is a very important inflammatory mediator. It is known that

By low stringency PCR amplification of genomic DNA using the primers designed based on the conservation of zinc finger motif, we got 8 gradient eletrophoretic bands. After recovery of the second and third bands, the DNA fragments in them were cloned

A novel human zinc finger gene, ZNF191, was assigned to chromosome 18 by hybridization of human/rodent hybrid cell panel to a full-length cDNA as a probe. Meanwhile, a human genomic DNA lambda/DASH library was screened using this cDNA probe and sever

The polymorphics of two pericentric (GT)n sequences on the long arm of human chromosome 21 have been analyzed after PCR amplification, PAGE and Ag-staining for the first time in 50 Chinese Han people, and were used to detect meiotic origin of the ext
