With the development of marine science and technology, underwater ranging has been widely applied in underwater remote sensing, detection, and navigation. In this paper, we propose a method aimed at obtaining arbitrary distance underwater using frequency comb, i.e., measuring arbitrary...

Aiming at the problem of the low-velocity impact monitoring and localization of composite structures in the aerospace field, a real-time monitoring system based on fiber Bragg grating sensor network is designed, and a joint impact localization algorithm based on the correlation distance and the...

The compost microbial community structure is complex. How microbial interactions promote compost humification was still unclear. In this study, compost samples at different stages were collected for high-throughput sequencing; a microbial network was constructed, and functional microorganisms...

In this paper, the theoretic analysis by stochastic dynamics and numerical simulation by ANN algorithm for tumor-immune models driven by random noises are studied. Firstly, a mathematical model about the competition between tumor cells and immune system is established based on the...

There are two kinds of traffic congestion at a toll plaza on a highway: congestion in the approach zone and congestion in the departure zone, which has received less attention. The performance improvement in the departure zone can directly reduce congestion in that area and indirectly increase...

In this work, magnetic S-doped Fe-Cu-La trimetallic oxides (S-FeCuLaO) was prepared and adopted as a adsorbent to remove Cr(VI) from aqueous solutions. The S-FeCuLaO material was characterized by SEM, XRD, FTIR, XPS and VSM, and batch adsorption experiments were employed to investigate to the...

An experimental study has been conducted to investigate the characterisitcs of subsonic steam jet condensation pressure oscillations in the ranges of steam mass flux 50-90 kg/m 2 s, water temperature 20-90 ℃ and vessel pressure 0.1-0.4 MPa. High frequency dynamic pressure and high speed images...

Elimination of NOx from the non-electric industrial boilers has become priority under the effective implementation of ultra-low emissions. A series of Ce-promoted FeVO4 catalysts with improved acidity and reducibility have been synthesized in this work. Thereinto, 10Ce/FeVO4 exhibited an optimum...

Monoamine neurotransmitters such as L-epinephrine (EPI), norepinephrine (NE), dopamine (DA), and serotonin (ST) are important biomarkers for neurological diseases. However, specific detection of a single monoamine neurotransmitter is challenging. In this work, a water-stable fluorescent...

Transition metal sulfides (TMSs), as highly promising candidate anode materials, are gradually attracting the attention for lithium-ion batteries (LIBs) recently on account of its multiple valence states as well as considerable capacity. Nevertheless, TMSs have relatively low inherent electronic...
