The global incidence of pediatric obesity has increased rapidly over the past few decades.Scientific evidence has repeatedly shown that behavioral and emotional challenges are frequently observed in children with overweight or obesity[1-2],as evidenced by a landmark case-control design study revealing that obese children have 7.15 times higher odds of developing mental health disorders in adolescence than their normal-weight peers[1]. 展开更多

本研究以现有回转窑焙烧工艺为基础,开发一种新型静态高温焙烧工艺。该工艺可适用于处理不同品位和种类的铬矿石原料,甚至含铬危废,可以提高铬收率,降低能耗。试验结果表明,反应温度为1050~1100℃,升温时间为120~150 min,保温时间为30 ... 本研究以现有回转窑焙烧工艺为基础,开发一种新型静态高温焙烧工艺。该工艺可适用于处理不同品位和种类的铬矿石原料,甚至含铬危废,可以提高铬收率,降低能耗。试验结果表明,反应温度为1050~1100℃,升温时间为120~150 min,保温时间为30 min时,可获得最佳铬收率。与回转窑不同,静态焙烧中,原料细度和料层厚度是影响能耗和反应时间的关键因素。粒径10~20 mm的粉状原料最适宜。该新工艺扩大低品位难处理铬资源的利用途径。 展开更多

The volume of securely encrypted data transmission increases continuously in modern society with all things connected.Towards this end,true random numbers generated from physical sources are highly required for guaranteeing security of encryption and decryption schemes for exchanging sensitive information.However,majority of true random number generators(TRNGs)are mechanically rigid,and thus cannot be compatibly integrated with some specific flexible platforms.Herein,we present a flexible and stretchable bionic TRNG inspired by the uniqueness and randomness of biological architectures.The flexible TRNG film is molded from the surface microstructures of natural plants(e.g.,ginkgo leaf)via a simple,low-cost,and environmentally friendly manufacturing process.In our proof-of-principle experiment,the TRNG exhibits a fast generation speed of up to 1.04 Gbit/s,in which random numbers are fully extracted from laser speckle patterns with a high extraction rate of 72%.Significantly,the resulting random bit streams successfully pass all randomness test suites including NIST,TestU01,and DIEHARDER.Even after 10,000 times cyclic stretching or bending tests,or during temperature shock(-25-80℃),the bionic TRNG still reveals robust mechanical reliability and thermal stability.Such a flexible TRNG shows a promising potential in information security of emerging flexible networked electronics. 展开更多
