Although it is widely believed that China facing a major shortage of pediatricians, the real situation current national status pediatric human resources and their working conditions has not been evaluated to date.We administered survey 54 214 hospitals from all 31 provinces in mainland 2015 2016. Hospital directors secondary tertiary with services random sample (10%) primary provided information on number pediatricians educational levels, specialties, workloads, dropout rates, other hospital...
An extended Kalman-based interacting multiple model (EK-IMM) smoother is proposed for mobile location estimation with the data fusion of time arrival (TOA) and received signal strength (RSS) measurements in a rough wireless environment. The Kalman filter used nonlinear estimation. IMM employed as switch between line-of-sight (LOS) non-LOS (NLOS) states, which are considered to be Markov process two interactive modes. Combining filtering scheme accurately smooth range corresponding base...
The golden pompano (Trachinotus ovatus) is an economically significant warm-water aquaculture species in China. time required for sexual maturity of T. ovatus relatively long. Consequently, it has prompted researchers to investigate gonadal development process this fish. To gain further insight into the function competing endogenous RNA (ceRNA) gonads and regulatory mechanism ceRNA network, whole transcriptome libraries were constructed from testes ovaries. Overall, a total 96 differentially...
The location of mobile station is an important issue for wireless communication systems. A estimation scheme using fuzzy-based Interacting Multiple Model (IMM) smoother proposed in this paper. It combines the time-of-arrival (TOA) and received signal strength (RSS) measurements to achieve high accuracy. fuzzy technique used interpolate several linear equations approximate nonlinear RSS measurement. IMM employed as a switch between line-of-sight (LOS) non-line-of-sight (NLOS) states which are...
In this paper, the relative location estimation problem, a prominent issue faced by several applications in wireless sensor networks (WSNs), is considered. Sensors are classified into two categories: location-aware and location-unaware sensors. To estimate positions of sensors, exact often assumed for However, practice, such precise data may not be available. Therefore, determining sensors presence inexact primary focus study. A robust min-max optimization method proposed problem minimizing...
Channel estimation is an important issue for wireless communication systems. A channel scheme using a Takagi-Sugeno (T-S) fuzzy-based Kalman filter under the time-varying velocity of mobile station in multiple-input multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) system proposed this paper. The fuzzy technique used to interpolate several linear models approximate nonlinear system. MIMO with space-time block coding (OSTBC) considered, where radio modeled as...
As technology advances, many countries have now opted for electronic voting systems. Any system must follow principles of transparency and impartiality in order to achieve fairness; the process also be protected against cyberattacks or denial-of-service attacks (DDOS) because such may affect processing time procedures even hinder fairness voting. This study establishes a network security mechanism systems based on blockchain technology. The employs distributed architecture that can prevent...
An adaptive two-loop power tracking control scheme is proposed for direct sequence code-division multiple-access (DS-CDMA) cellular systems in a wireless network. The includes an outer-loop controller and inner-loop controller. searching algorithm designed determining optimal target signal to interference noise ratio (SINR) each user the outer loop. utility optimization can be achieved by using through net function based on quality of service (QoS) purpose resource management communication...

The microstructural stability and property evolution of high-temperature titanium alloys under long-term conditions has been a critical scientific issue in the field advanced alloys. In this work, we systematically investigated precipitation behavior silicides ordered α2 phase, which are closely related to Ti65 alloy, during thermal exposure at 650 °C for different periods time. Furthermore, effects on mechanical properties were evaluated using room temperature high tensile tests,...
The TiCp can act as heterogeneous nucleation site and greatly refine the grain size of aluminum alloy has been widely accepted (stage I).

This paper presents a 12-bit 270MS/s pipelined analog-to-digital converter (ADC) without employing front-end sample-and-hold amplifier. A novel strategy is established to diminish the aperture error while maintaining both original tracking time and amplifying of multiplying digital-to-analog (MDAC). It matches signal paths between comparators MDAC in first stage by using proper timing sequence high-speed dynamic comparators. The measurement results show 63.7dB SNR 76.1dBc SFDR at 120.1MHz...
