To report the global, regional, and national burden of type 2 diabetes mellitus (T2DM) in 2019, assess its trends past, forecast future.The main data source was Global Burden Disease 2019 database. We assessed changes T2DM from 1990 to with joinpoint regression analysis. Age-period-cohort analysis used incidence mortality rate 2020 2034.The has increased generally. The low-middle socio-demographic index (SDI) region had highest increase age-standardized (ASIR), prevalence (ASPR), (ASMR),...
We demonstrate ultrahigh-sensitivity silicon photonic sensors based on two cascaded double-ring resonators operating in transverse-magnetic mode. Both wavelength interrogation and intensity methods are experimentally investigated the sensitivities reached 24,300 nm/RIU 2430 dB/RIU, respectively. also show that can be simply to realize simultaneous detection of multiple species, which is very promising for low-cost array applications.
The objective of this study was to understand dynamic global and regional lung cancer fatality trends provide a foundation for effective prevention treatment strategies. Data from 1990 2019 were collected the Global Burden Disease (GBD) database statistical analysis conducted using Excel 2010. Standardization based on GBD's world population structure, Average Annual Percentage Change (AAPC) calculated Joinpoint 4.8.0.1 software. Bayesian age-period-cohort (BAPC) predicted mortality 2020...
This paper introduces two kinds of handover algorithms that adjust the (HO) parameters LTE (Long-Term Evolution) eNodeB (evolved NodeB) to improve overall network performance and diminish negative effects. The focus is on impact compare A3 event based optimization hysteresis time-to-trigger in different velocity environment SINR. Both have been designed implemented a dynamic system level simulator investigated for parameter sets high-speed railway) simulation scenario. Reference Signal...
Abstract Subsequent commutation failure (SCF) can be easily generated during the first (CF) recovery process in a line-commutated converter-based high voltage direct-current system. SCF poses significant threat to safe and stable operation of power systems, accurate prediction CF is thus important. However, affected by operating characteristics main circuit coupling effects sequential control response inverter station. These are difficult predict accurately. In this paper, new method...
This paper proposes a novel sequential asynchronous fusion algorithm by using the idea of discretization sampling points based on continuous and distributed multi-sensor linear dynamic system. Firstly, it maps unifies all measurements in reference frame clock with centre. Secondly, selecting every time period to discretize state system sequentially, we get equation relevant measurement between point this period. Finally, best Kalman filter sense LMMSE directly, filtering can be realized....
This paper attempts to evaluate the transformation and upgrading (T&U) levels of three industries in 11 prefectures Zhejiang Province, China, since 2016. Taking provincial T&U as benchmark, each prefecture were analyzed by shift-share method (SSM). The main results are follows: In terms primary industry, none had structural advantage (structural shifts < 0), but 3 regional competitiveness (competitiveness > 0); secondary 5 tertiary all 6 Shaoxing was competitive industries,...
Commutation failure (CF) can easily occur in line-commutated converter-based high-voltage direct current (LCC-HVDC), which causes the renewable energy tripping off from grid and cascading failures. Given that first CF (FCF) be hardly avoided, suppressing subsequent (SCF) becomes key to ensuring safe operation of large-scale AC/DC hybrid power grids. The advanced control through predicting is most effective method suppress or reduce bad influence CF. However, existing prevention implemented...
