The mechanism of latent tuberculosis (TB) infection remains elusive. Several host factors that are involved in this complex process were previously identified. Micro RNAs (miRNAs) endogenous ∼22 nt play important regulatory roles a wide range biological processes. studies demonstrated the clinical usefulness miRNAs as diagnostic or prognostic biomarkers various malignancies and few nonmalignant diseases. To study role transition from to active TB discover candidate transition, we used human...
Abstract The geometric shape and arrangement of individual cells play a role in shaping organ functions. However, analyzing multicellular features exploring their connectomes centimeter-scale plant organs remain challenging. Here, we established set frameworks named large-volume fully automated cell reconstruction (LVACR), enabling the exploration 3D cytological cellular connectivity tissues. Through benchmark testing, our framework demonstrated superior efficiency segmentation aggregation,...
NITRATE TRANSPORTER 1.1 (NRT1.1) functions as a dual affinity nitrate transceptor regulated by phosphorylation at threonine residue 101 (T101). Previous studies have suggested that NRT1.1 is involved in stomatal opening and contributes to drought susceptibility. However, the precise mechanism of how status affects movement tolerance remains unclear. In this study, we observed seedlings expressing phosphorylated form (NRT1.1T101D, T101D) exhibited increased compared dephosphorylated...
This paper comprehensively analyzes the channel transmission characteristics of low earth orbit satellite. On this basis, problems when each physical layer process terrestrial 5G new radio is directly applied to LEO satellite access network further analyzed, then feasible implementation schemes for integrated are carefully designed. Furthermore, core technologies key step briefly discussed.
In this paper, we propose a novel distributed multi- satellite cooperative transmission (DMCT) system model. Based on the analysis of channel correlation between multiple antennas satellites and single smartphone in model, design three types connection modes under different scenario configurations by drawing terrestrial mature MIMO technologies. Then, further discuss analyze application limitations main characteristics each mode. Finally, several key technologies that need to be conquered...
Abstract The workspace mapping method for master-slave isomeric robots is a key research direction. In order to enhance the safety and stability of operation such robots, position-joint hybrid based on edge drifting proposed in this paper. First, teleoperation divided into two phases, that is, task approach operation. During approach, algorithm adopted largely cover robot. Rate used quickly control movement slave robot target position. operation, integrating Cartesian space joint highly...
Reducing the energy consumption of trains plays an important role in sustainable development subway system. When timetables are generated mainly considering passenger satisfaction, there still some margins to optimize them improve efficiency. This paper slightly reoptimizes planned timetable reduce by improving utilization regenerative braking energy, while not changing number trains. To this purpose, authors innovatively propose a periodic or off-peak optimization method coordinate arrivals...
Hand-eye calibration can unify the robot coordinate system and measurement system, but process is easily affected by geometric parameter error of body drift joint angles. Therefore, this paper proposed an improved 3D-position-based hand-eye method, a refinement existing process. By controlling manipulator to only rotate it's single joint, method fitted axis rotating used properties obtain part rotation information relationship. As was not parameters angles, correct results. A simulation...
The utilization of regenerative braking energy is great significance to the saving subway. Therefore, this paper proposes an optimization method for scheduling and control integration, which not only adjusts timetable but also optimizes speed curves trains. When there a train braking, will try find that accelerates absorb generated by train. Firstly, establishes model, based on be optimized. Furthermore, we design algorithm genetic algorithm, trains binary search obtain good solution....
With the development of railway transportation and increase in freight transport volume, number lines trains are continuously increasing. How to effectively reduce energy consumption has become a research hotspot. This paper considers length weight trains, calculates equivalent gradients lines. Using train dynamics model, ramps divided into four types: steep uphill section, general downhill section section. At same time, based on optimal control strategy obtained by Pontryagin's Maximum...
Aiming at the problem of satellite power limitation, this paper proposes a distributed multi-satellite cooperative transmission (DMCT) scheme based orthogonal time frequency space (OTFS) for low earth orbit (LEO) networks to achieve downlink and performance enhancement. Firstly, we construct DMCT system model channel model. Through theoretical analysis, it is found that dynamic change phase difference between each data stream from cluster arriving terminal will cause serious time-varying...
This paper proposes a channel estimation method based on discrete prolate spheroidal base extension model (DPS-BEM) for 5G integrated low earth orbit (LEO) satellite systems, which takes the cascade structure of least square (LS) estimator and Kalman filter as core. Firstly, DPS-BEM is utilized to accurately fit time-domain state matrix. The preliminary coefficients basis function could be acquired by simple easy implemented LS estimator. Subsequently, filtering cascaded attenuate influence...
