With the rapid development of satellite internet, the shortage of bandwidth and spectrum resources has become Console increasingly prominent.Satellite laser communication has the characteristics of large bandwidth and no spectrum constraints, which makes it an effective means to alleviate the shortage of radio frequency resources and improve the co
In this paper, the conditions under which the occurrence of the local bifurcation (such as saddle-node (SN), transcritical (TC), and pitchfork (PT)) of all stable points of a food web model have been investigated.Fear Belts and anti-predator responses involving the Holling-type IV and Growly-Martin functional responses have been found.It has been s
Digital agriculture is exciting attention because of an expectation that food systems will be disrupted by new digital technologies through improvements in precision, efficiency, volume, speed of process or identity of product.This is against the background of the drive for sustainability in food systems.A diversity of technology applications is un
BackgroundThis study aimed to evaluate the efficacy and safety of sequential immune checkpoint inhibitors (ICIs) plus bevacizumab therapy after radiotherapy for portal vein tumour thrombosis (PVTT) in patients with hepatocellular carcinoma (HCC).MethodsRetrospective data were collected from 113 patients with HCC with PVTT.Patients in the PVTT radio
Pemanas air energi surya merupakan suatu sistem pemanas air dengan cara kerja menyerap energi radiasi matahari yang kemudian diubah menjadi energi panas dan ditransfer menuju fluida kerja melalui pipa air.Pemanas air ini dibagi menjadi dua yaitu pemanas air kolektor tabung dan pemanas air kolektor plat datar.Dilakukan penelitian dengan menambahkan
