Arbuscular mycorrhizal fungi (AMF), ubiquitous soil that form symbiotic relationships with the majority of terrestrial plants, are known to play an important role in plant tolerance chromium (Cr) contamination. However, underlying mechanisms, especially direct influences AMF on translocation and transformation Cr soil–plant continuum, still unresolved. In a two-compartment root-organ cultivation system, extraradical mycelium (ERM) roots was treated 0.05 mmol L–1 Cr(VI) for 12 days...
Accurate navigation is essential for autonomous robots and vehicles. In recent years, the integration of Global Navigation Satellite System (GNSS), Inertial (INS), camera has garnered considerable attention due to its robustness high accuracy in diverse environments. However, leveraging full capacity GNSS cumbersome because choices formulations, error models, satellite constellations, signal frequencies, service types, which lead different precision, robustness, usage dependencies. To...
To explore the effects of different physical training programs on sleep boy students in a senior high school, and to provide reference for effectively improving level as well optimizing program. 77 boys 11th grade school were randomly divided into four groups: Group I (traditional training), II (strength III (HIIT IV +HIIT training). At points before after intervention, Pittsburgh Sleep Quality Index (PSQI) examination scores measured indicators health academic performance intervention...
Abstract In modern industrial production, the health status of rolling bearings is critical to safe and stable operation mechanical equipment. Deep learning methods are able automatically capture deep abstract features contained in bearing vibration signals an end-to-end manner, which displays prominent unparalleled advantages over traditional signal processing feature selection algorithms. Recently, xLSTM (Extended Long Short-Term Memory) realizes a major innovation classic time series...
Using a standalone camera for pose estimation has been quite standard task. However, the point correspondence-based algorithms require at least four feature points in field of view. This paper considers situation that there are only two points. Focusing on attitude estimation, we propose to fuse with low-cost inertial sensors based nonlinear complementary filter design. An implicit geometry measurement model is derived using an image. fused angle rate and vector from proposed parameters be...

Considering deployment to UAVs, algorithm uses YOLO-tiny network model as baseline ensure balance speed accuracy, adds Convolutional Block Attention Module (CBAM) improve model's ability learn important features, utilizes data augment methods such mosaic mixup effectively performance for reduce targets. The...
The advanced receiver autonomous integrity monitoring (advanced RAIM, ARAIM) is the next generation of RAIM which widely used in civil aviation. However, current ARAIM needs to evaluate hundreds subsets, results huge computational loads. In this paper, a method using subset excluding entire constellation single satellite fault subsets and simultaneous multiple satellites presented. proposed algorithm based on tight integration global navigation system (GNSS) inertial (INS). number that...
Operating reliability has great significance for equipment condition monitoring and health evaluation. In terms of to be evaluated, assessment is a personalized problem. Traditional method relies on the probability mathematical statistics methods, limited practical when it used real-time specific equipment. this paper, characteristics challenges operational large are analyzed, methods improvements in research summarized. general, divided into two categories, which model-based mapping-based...
The vibration signal collected from rotating structures with faulty bearings is a typical multi-component and that fault features are often submerged by strong interferences. To accurately extract features, hybrid method based on variational mode decomposition (VMD) stochastic resonance (SR) proposed for weak feature enhancement in bearing diagnosis. Firstly, the decomposed VMD to obtain several sub-signals or modes. Then, sensitive which contains main information chosen according kurtosis...

The short spreading code used by the BeiDou Navigation Satellite System (BDS) B1-I or GPS Coarse/Acquistiion (C/A) can cause aggregately undesirable cross-correlation between signals within each single constellation. This GPS-to-GPS BDS-to-BDS correlation is referred to as self-interference. A C/A self-interference model extended propose a for BDS B1, taking into account unique feature of signal transmitted medium Earth orbit (MEO) and inclined geosynchronous (IGSO) satellites-an extra...
This study aimed to provide evidence of validity and reliability for the Perceived Mattering Questionnaire-Physical Education (PMQ-PE) developed by Richards et al. (2017) Chinese physical education (PE) teachers. The PMQ-PE consisted two factors (i.e., PE matters teacher matters) with four items in each, measuring dimensions (attention, importance, dependence, ego-extension). (PMQ-PEC) was validated among 1,278 elementary secondary school teachers China, whom 59.0% were 70.2% males....
<h3>Abstract</h3> Integrity, a safety-of-life framework from civil aviation for satellite navigation, is greatly under-explored in visual navigation. A new two-factor approach to rejecting measurement outliers proposed navigation integrity stereo odometry (VO). In contrast other treatments using reprojection error as residuals, our choice of landmark matching inherently connects solutions and monitoring. We propose two methods detect large residuals that cannot otherwise be identified by...

Comparing transmission’s performance before with that after optimization, result shows motor difficulty reduced improved optimaization.
This paper is concerned with using a high-order linearised Euler solver to calculate the propagation of idealised landing gear noise sources. Two different configurations are considered. One flat plate and cavity simulate wind tunnel tests second under high lift wing. Both cases considered mean flow effects. sources monopole source at constant frequency other time dependent omni-direction source. The origin was from CFD simulation. results show how were modified by effect solid walls...
