Hearing loss is one of the most common sensory disorders worldwide,affecting approximately 466 million people,including 34 million children[1].Genetic mutations accounts for approximately 60%of inherited hearing loss cases[2.3].These genetic changes result in a wide variety of clinical manifestations,ranging from nonsyndromic hearing loss(NSHL)to over 400 syndromes involving hearing loss and from mild adult-onset hearing loss to profound congenital deafness,covering the entire spectrum of Mendelian inheritance.

Limiting the bandwidth of BT may be an efficient way to control it.

利用39所“双一流”建设高校2.48名学术型博士生的调查数据,分析知识共享对博士生科研创新能力发展的影响机制。研究发现,博士生知识共享水平较高,学习投入有待提升,科研效能感明显不足,发展型科研创新能力略有提高,任务型科研创新能力稍微下降。博士生知识共享显著正向影响学习投入、科研效能感及科研创新能力。博士生学习投入在知识共享与科研创新能力的关系上具有部分中介效应,而科研效能感在知识共享与科研创新能力的关系上具有完全中介效应,学习投入及科研效能感在知识共享与科研创新能力的关系上具有链式中介作用。为促进博士生科研创新能力发展,大学要重视博士生知识共享的价值及作用,疏通知识传播渠道;创设良好培养环境,强化博士生学习投入;增强博士生科研效能感。

With the rapid development of the automobile industry in China, there is an ever-increasing demand for long-life cold working dies used for punching automobile components. However, the full potential of such advanced surface engineering {2. as PVD coatings and duplex surface treatments in cold work dies has not been realized. In the present study, Crl2.oV steel has been surface engineered by single PVD Ti/TiN coating and duplex treatment combining low temperature plasma nitriding (LTPN) with PVD Ti/TiN coatings. The properties of Ti/TiN coatings in terms of surface morphology, microhardness, load bearing capacity, bonding strength and wear resistance were evaluated by microhardness, scratch and wear tests. The experimental results show that PVD Ti/TiN coatings can significantly enhance the surface load bearing capacity (especially for duplex treatments) and wear resistance of Crl2.oV steel by more than one order of magnitude. This can be mainly attributed to the hard and well-adherent PVD Ti/TiN surface coatings and strong mechanical support of the LTPN sublayer. While two-body abrasive wear prevails for uncoated Crl2.oV, the micropolishing action of the counterface dominates in surface engineered material.
