Within the nanoscale, methodically reconfiguring interface charges, and leveraging this newly structured interface to modify the energy‐momentum dynamics of heterojunction energy bands, hold profound implications for microwave electronics because of the intensified interaction between external microwaves and interfaces of materials. Mastering the orderly reconstruction of interface charges, contingent...
This study aimed to explore the effect and the molecular mechanism of tetrahedral framework nucleic acids (tFNAs), a novel self‐assembled nanomaterial with excellent biocompatibility and superior endocytosis ability, in inhibition of pathological retinal neovascularization (RNV) and more importantly, in amelioration of vaso‐obliteration (VO) in ischaemic retinopathy. tFNAs were synthesized from four...
Two new switched-current (SI) memory cells suitable for high-speed digital communication circuits are introduced. A kind of novel BiNMOS technology is introduced in the first switched-current memory cell, and a high-speed fully differential BiCMOS structure is introduced in the second switched-current memory cell. Besides, measures of deducing the delay time formulae, optimum seeking the Parameters,...
This paper focuses on the organizational management of overseas R&D by Chinese companies based on the framework created by Zedtwitz. We find that the majority China multinational companies take overseas R&D activities through cooperative projects and united labs with those associations in developed countries; a small group of multinational companies with solid international experience tend...
The firm growth factors is an important topic in firm growth research. The scholars in this field have achieved significant outcomes by empirical study and factors model. This paper summarized the firm growth factors outcome and identified its the future trend by literature review.
This paper aims to find out the overseas R&D location determinates of MNEs in Japan and the US. This paper found that the location determinates of American overseas R&D are impacted by GDP, GDPP, HTE, R&D/GDP, IPP, SCI, CCR and FREE of host countries, and it shares the same location determinates no matter investing in developed or developing areas. As the late comer of overseas R&D,...
The LC filter introduced to the AC side of three-phase current source PWM rectifier, brought leading power factor. In addition, because of the nonlinearity of the PWM rectifier, the satisfactory effect could not be obtained with the traditional PID control system under larger disturbance and changes of controlled object. This paper described the technology of Combining traditional PID control with...
A kind of novel CMOS optically coupled isolation amplifier (OCIA) composed of two operational amplifiers (OAs) is present. To improve the linearity and reduce the power consumption, the negative feedback signal is introduced to the input loop through two photoelectric coupled devices. Besides, other improvement actions are taken in this amplifier. Experimental results show that compared with the BiCMOS...
