The Internet of Things (IoT) revolution has shown potential to give rise many medical applications with access large volumes healthcare data collected by IoT devices. However, the increasing demand for privacy and security makes each device an isolated island data. Further, limited computation communication capacity wearable devices restrict application vanilla federated learning. To this end, we propose advanced learning framework train deep neural networks, where network is partitioned...

Reflecting upon China's current path of regional urbanization, this research studies the polycentric structure megaregions. It defines concept and measurement for megaregional polycentricity utilizes spatial statistics tool—standard deviational ellipse directional distribution—to measure demographic pattern individual The result reveals that most megaregions in China do not have significant polycentricity. They are either dominated by a single major center or number centers clustered...

Previous researches often claim the benefits of technology business incubators (TBIs). There is, however, little systematic evidence TBIs' role in promoting local economic growth China where regions are different development stages. Furthermore, no study has examined contribution to convergence. This paper aims answer this question, based on panel data Chinese national and host cities from 2008 2012. The results indicate that there exists convergence both nationwide western been found...

This paper aims to examine the co-movement between two economic powers, namely USA and China. The authors are mainly interested in examining dynamics of co-movements during, pre-covid periods. Additionally, they have aimed volatility spillover China, during In order achieve research-based objectives, advanced econometrics models been applied data from July1, 2010, April 30, 2021. results show that sample market is integrated long run. also indicate behaviour Chinese same as US market, offers...

Improved mobility and accessibility for passengers goods provide competitive advantages megaregions. This article describes the trends in China's top three megaregions—the Capital Economic Zone, Yangtze River Delta, Pearl Delta—and how megaregional planning has led to solutions challenges of mobility. experience is compared with megaregions United States European Union. comparative context confirms that existing regional carry severe energy environmental movement toward rail, particularly...

This study aims to examine the key policy paradigms and strategy dynamics that drive development of aircraft spacecraft manufacturing (ASM) in China. Using Science & Technology activities data Chinese ASM from 1995 2010, we find government technology enterprise both are positively related innovation performance ASM. Our results also indicate industry is more dependent on improvement domestic than foreign import. Furthermore, indigenous has been chosen by China as main paradigm. Finally,...

The exacerbation of the concentration population and economic activities in a few core metropolitan areas has become an urgent issue for China’s regional development, necessitates more polycentric spatial development pattern. Transportation infrastructure improvement can serve as vital instrument to achieve objective development. Focusing on 10 megaregions China, this research examines fundamental urban context massive investment highway railway: impacts road rail network pattern growth...

This paper investigates the impacts of airports on regional economic growth using county-level data in China from 2000 to 2019. Firstly, this constructs air accessibility index, which measures airport activities and improves previous measurements by adding flight frequency as weight. Secondly, address endogeneity problem determining location, uses instrument variable adopts two-stage least squares method. historical estimated based network 1957 instrumental variable. The finds following. (1)...

This paper conducts surveys on the design, construction and use of ICF system, a new type low-energy industrialized house that has emerged in Guanzhong rural area China recent years. The survey content includes family background, layout cost, details energy consumption simulation, temperature test etc. summarizes reasons for popularity system issues need attention future promotions. Construction optimization is also proposed thermal bridge at window opening, so this can exert more...

Abstract A large number of existing high-rise residential buildings in China have problems such as high energy consumption and poor comfort. Renovating them is an important way for sustainable urban development. This article first introduces a European sunspace addition method residences, then sets up unit models different depths simulation. Four cities cold regions are selected simulation comparison original state, conventional renovation, its variants made. The size the window, presence or...

In VLBI, obtaining group delay characteristics of equipment is essential to ensure the measurement accuracy.The thesis proposes a new method, nonlinear fitting by analyzing how get with direct phase difference method and linear-least-squares method.The result simulation shows that measure two orders magnitude more accurate than method.Actual data demonstrates linear lose effectiveness in frequency from 270MHz 370MHz.Otherwise, method's precision better 0.1ns.
