This paper investigates the robust tracking control of unmanned aerial vehicles (UAVs) against external time-varying disturbances. First, by introducing a virtual position controller, we innovatively decouple the UAV dynamics into independent position and attitude error subsystems, transforming the...

Accurate estimation of heading direction from optic flow is a crucial aspect of human spatial perception. Previous psychophysical studies have shown that humans are typically biased in their heading estimates, but the reported results are inconsistent. While some studies found that humans generally...

Microplastics threaten terrestrial ecosystems, with biodegradable types potentially amplifying soil organic carbon losses through the priming effect. However, the response of microplastic-induced priming effect to global warming across ecosystems remains largely unknown. Here, we collected soils fro...

Due to flow induced vibration caused by coolant circulation, fretting wear inevitably occurs between fuel cladding, heat exchanger tubes and their holders in Gen IV lead-bismuth eutectic (LBE) cooled nuclear reactors. Focusing on this issue, in the current work, fretting wear behavior and damage mec...

Fractal theory of particle size distribution (PSD) is a widely used approach in soil science. However, fractal studies on sandstone PSDs are scarce in sedimentology and geology. Taking littoral sandstones in the Carboniferous Donghetang Formation of the Hade Oilfield as an example, fractal dimension...

Rock slopes, composed of intact rock masses and relatively weak discontinuities, exhibit stability primarily governed by the spatial distribution of these discontinuities. Under the framework of structural control theory, acquiring discontinuity information is a fundamental prerequisite for rock slo...

Nuclear receptors (NRs) are ligand-activated transcription factors that function as metabolic sensors, integrating endogenous and xenobiotic signals to regulate gene networks controlling metabolism, immunity, and cellular homeostasis. Recent studies elucidated the pivotal roles of NRs (e.g., PPARs,...

RING is a really interesting new gene which plays important regulatory roles in many developmental processes as well as in plant-environment interactions. In the present report, the ZmRHCP1 gene encoding a putative RING-HC protein was isolated from maize and characterized. The ZmRHCP1 protein contai...

Near-infrared (NIR) photoelectric synaptic devices show great potential in studying NIR artificial visual systems integrating excellent optical characteristics and bionic synaptic plasticity. However, NIR synapses based on transition metal dichalcogenides (TMDCs) suffer from low stability and poor e...

Phenolic acids (PAs), which can exert toxic effects on seed germination and plant growth, are the most common allelopathic substances found in soils. To better understand the degradation fates of PAs in the rhizosphere of halophytes, five haloalkaliphilic PA-degrading bacteria, which were identified...

The cell division cycle 20, a key component of spindle assembly checkpoint, is an essential activator of the anaphase-promoting complex. Aberrant expression of cell division cycle 20 has been detected in various human cancers. However, its clinical significance has never been deeply investigated in...

Background Intratumoral fungi have recently been implicated in cancer initiation and progression, with potential as biomarkers for predicting clinical outcomes and treatment response in patients with cancer. However, their role in acral melanoma (AM) has not been previously explored.Methods We chara...

Insulin-like growth factor 2 messenger RNA-binding proteins have been described to associate with malignant process in many cancers. However, the role of insulin-like growth factor 2 messenger RNA-binding protein family has not been thoroughly elucidated in non–small cell lung cancer. This study was...

Efficient siRNA delivery is highly desirable for disease treatment. However, the application of conventional nanoparticles is limited by the inability to escape from endo-lysosomes. Herein, we report a strategy using small-molecule drugs to enhance siRNA endo‐lysosomal release,addressing this challe...
