Tongue diagnosis is a unique method in traditional Chinese medicine (TCM). This the first investigation on association between tongue and coating microbiome using next-generation sequencing. The study included 19 gastritis patients with typical white-greasy or yellow-dense corresponding to TCM Cold Hot Syndrome respectively, as well eight healthy volunteers. An Illumina paired-end, double-barcode 16S rRNA sequencing protocol was designed profile tongue-coating microbiome, from which...
The development of gastritis is associated with an increased risk gastric cancer. Current invasive diagnostic methods are not suitable for monitoring progress. In this work based on 78 patients and 50 healthy individuals, we observed that the variation tongue-coating microbiota was occurrence gastritis. Twenty-one microbial species were identified differentiating microbiomes individuals. Pathways such as metabolism in diverse environments, biosynthesis antibiotics bacterial chemotaxis...
In this article, an intelligent predictor-corrector entry guidance approach for lifting hypersonic vehicles is proposed to achieve real-time and safe control of flights by leveraging the deep neural network (DNN) constraint management techniques. First, trajectory planning problem formulated as a univariate root-finding based on compound bank angle corridor, two algorithms are presented enforce satisfaction both path terminal constraints. Second, DNN developed learn mapping relationship...
Solar sail spacecraft are proposed to accomplish body-fixed hovering missions over elongated asteroids. The flight is maintain a fixed position relative the surface of spinning asteroid. A solar without fuel consumption can greatly expand range locations in variable lightness number for an extended period. rotating mass dipole used produce gravitational field created by Dynamic equations obtained approximate model terms specified conditions. Feasible regions asteroids presented and analyzed...
To improve the autonomy and reliability of asteroid landings, an intelligent approach to fast reliable generation optimal landing trajectories is proposed. Unfortunately, indirect methods require good initial guesses for shootings. address this issue, deep neural networks (DNNs) are developed approximate costates supply solutions achieve high success rate This article focuses on following three contributions. First, original problems connected with two-dimensional (2-D) asteroid-free...
Recently, Near Earth Objects (NEOs) have been attracting great attention, and thousands of NEOs found to date. This paper examines the NEOs' orbital dynamics using framework an accurate solar system model a Sun-Earth-NEO three-body when are close search for with low-energy orbits. It is possible such NEO be temporarily captured by Earth; its orbit would thereby changed it become Earth-orbiting object after small increase in velocity. From point view restricted system, whose Jacobian constant...
Configuration stability is crucial for the detection accuracy of space-based gravitational wave (GW) detectors. This paper proposes a low-frequency hierarchical cooperative impulse control strategy and high-fidelity orbit optimization method to achieve formation GW detectors with high performance. The employs structure divide configuration into position shape layers. In upper layer, state transition tensor employed analyze sensitivity feasible range center on stability. lower novel...
A non-invasive glucose measurement system based on the method of metabolic heat conformation (MHC) is presented in this paper. This consists three temperature sensors, two humidity an infrared sensor and optical device. The level can be deduced from quantity dissipation, blood flow rate local tissue degree oxygen saturation. methodology data process error are also analyzed. applied a primary clinical test. Compared with results commercial automated chemistry analyzer, correlation coefficient...
Main-belt asteroids are of great interest for scientific exploration and engineering implementation. This paper investigates the accessibility main-belt trajectories to reach them. The effects gravity-assist maneuvers on orbital energy orientation plane explained. Tisserand graph is employed determine that Mars most useful body asteroid missions. An assessment all over 100 km in diameter carried out. global minimum velocity increments direct transfer trajectory obtained each candidate...
