Peptidic mimics of the gut hormone glucagon-like peptide (GLP) 1, exemplified by recently approved drug exenatide, show promise as therapies for type 2 diabetes. Such "incretin mimetics" regulate glucose appearance in plasma and can restore glucose-stimulated insulin secretion without excess risk hypoglycemia. The need injection, which may limit use peptidic GLP-1 receptor (GLP-1R) agonists, has driven largely unsuccessful efforts to find smaller molecules. failure identify orally effective...
Surface urban heat islands (SUHIs) have been investigated in many regions around the world, but little attention has given with regard to SUHIs South America. In this study, Moderate Resolution Imaging Spectroradiometer (MODIS) land surface temperature (LST) data was used investigate diurnal, seasonal, and interannual variations SUHI intensity (SUHII, LST minus rural LST) 44 American cities different climate zones types of land. To examine effects factors that may influence SUHII,...
Using GNSS observable from some stations in the Asia-Pacific area, carrier-to-noise ratio (CNR) and multipath combinations of BeiDou Navigation Satellite System (BDS), as well their variations with time and/or elevation were investigated compared those GPS Galileo. Provided same elevation, CNR B1 observables is lowest among three BDS frequencies, while B3 highest. The code inclined geosynchronous orbit (IGSO) medium Earth (MEO) satellites are remarkably correlated systematic "V" shape trends...
The international GNSS monitoring and assessment system (iGMAS) tracking network has been established by China to track multi-GNSS satellites. A key feature of iGMAS stations is the capability fully new navigation signals from recently deployed BDS-3 In addition B1I B3I inherited BDS-2 satellites, satellites are capable transmitting open service signals, including B1C at 1575.42 MHz, B2a 1176.45 B2b 1207.14 MHz. this contribution, we present a comprehensive analysis characterization tracked...
The Japanese Quasi-Zenith Satellite System (QZSS) is a regional navigation satellite system covering the entire Asia-Oceania region. Except for standard signals, QZSS satellites also broadcast L6E augmentation signals with real time GNSS precise orbit every 30 s and clock messages 1 s, which very important necessary Real-Time point positioning (RTPPP) applications. In this paper, MADOCA real-time services derived from were evaluated both accuracy availability compared IGS final products. To...
SUMMARY Precise point positioning (PPP) can measure ground motions with a centimetre-level accuracy using only one receiver. It has been widely used in earthquake monitoring and early warning (EEW) systems. However, traditional PPP highly depends on well-established robust internet infrastructure for data communication. Along the broadcast ephemeris, orbit clock corrections transmitted by B2b signals of BeiDou Navigation Satellite System (BDS) be to recover precise products GPS BDS. Since...
With the development of Global Navigation Satellite System (GNSS) and opening Application Programming Interface (API) Android terminals, positioning research terminals has attracted attention GNSS community. In this paper, three static experiments were conducted to analyze raw observations quality performances smartphones. For two experimental smartphones, numbers visible satellites with dual-frequency signals are unstable not enough for Precise Point Positioning (PPP) processing all through...
For the same antenna type, numerical differences among phase center correction (PCC) models released by different institutes can reach several millimeters, which is far beyond nominal calibration accuracy. This contribution introduces a new method to evaluate consistency of these PCC models. We first investigated coupling offset (PCO) and variation (PCV) through simulation experiments, results show that calibrated PCO values under strategies may result in large differences, so do PCV due...
GNSS receiver antenna phase center variations (PCVs), which arise from the non-spherical response of signals have to be well corrected for high-precision applications. Without using a precise correction (PCC) model, estimated position station monument will lead bias up several centimeters. The Chinese large-scale research project "Crustal Movement Observation Network China" (CMONOC), requires positions in comprehensive GPS observational network motived establishment set absolute field...
Global navigation satellite system (GNSS) provides users with all-weather, continuous, high-precision positioning, navigation, and timing (PNT) services. In the operation use of GNSS, influence space environment is a factor that must be considered. For example, during geomagnetic storms, series changes in Earth’s magnetosphere, ionosphere, upper atmosphere affect GNSS’s positioning performance. To investigate performance global systems this study selected three storm events occurred from...
The broadcast ionospheric model is mainly used to correct the delay error for single-frequency users. Since BeiDou global correction (BDGIM) a novel BDS-3, its performance was analyzed through single point positioning (SPP) in this study. Twenty-two stations simultaneously receiving B1C, B2a, B1I and B3I signals were selected from International GNSS Service (IGS) Monitoring Assessment System (iGMAS) tracking networks SPP experiments. differential code bias (DCB) parameters hardware delays of...
A novel method for fault diagnosis based on wavelet and neural network of three-phase bridge inverter circuit is proposed in this paper. In the method, packet used to decompose signal extract characteristics effectively. BP PSO-optimized are perform tice circut diagnoses separately results both compared. Finally, modeled simulated MATLAB/Simulink platform. The result shows that PSO-BP nauTal has faster convergence dpeed higher diagnostic accuracy more effective power electronic circuits.
