China has sustained double-digit economic growth over three decades.A literature has emerged with one possible explanation: meritocratic promotion, where officials at the same level compete with each other on the basis of relative GDP growth, and the winners are rewarded with promotion up the administrative hierarchy.This tournament competition gen

Intelligent game adversarial algorithms not only make full use of the portrayal accuracy of the game model, but also solve the equilibrium solution through the powerful computational ability of neural network and the trial-and-error mechanism of reinforcement learning, which makes the intelligent game adversarial algorithms achieve good results in

Abstract Background Primary hyperoxaluria (PH) is a rare inborn disorder of the metabolism of glyoxylate, which causes the hallmark production oxalate and forms insoluble calcium oxalate crystals that accumulate in the kidney and other organs.Since the manifestation of PH varies from recurrent nephrolithiasis, nephrocalcinosis, and end-stage renal
