Researches on the atmospheric boundary layer (ABL) need accurate measurements with high temporal and spatial resolutions from a series of different instruments. Here, method for identifying cloud, precipitation, windshear, turbulence in ABL using single coherent Doppler wind lidar (CDWL) is proposed demonstrated. Based deep analysis power spectrum backscattering signal, multiple products, such as carrier-to-noise (CNR), width, skewness, turbulent kinetic energy dissipation rate (TKEDR),...
Rapid and sensitive antigen detection using a lateral flow immunoassay (LFIA) is crucial for diagnosing infectious diseases due to its simplicity, speed, user-friendly features. However, it remains critical issue explore specific biorecognition elements powerful signal amplification. In this study, taking SARS-CoV-2 as proof of concept, peptide, WFLNDSELIML, binding the spike (S) was identified by nonamplified biopanning method, which exhibited high affinity target, with dissociation...
Residual enrofloxacin (ENR) exposed in aqueous environments is challenging to the ecosphere. In this work, a layered double hydroxide CoAl-LDH was used activate common oxidizing agent persulfate (PS) for photodegradation of ENR, and degradation pathways ENR were scrutinized elucidated. The results indicated that, under optimal conditions obtained through orthogonal experiments, even though rate as high 97.72%, removal total organic carbon (TOC) from system only about 30%. Eleven probable...
The global spread of monkeypox has become a worldwide public healthcare issue. Therefore, there is an urgent need for accurate and sensitive detection methods to effectively control its spreading. Herein, we screened by phage display two peptides M4 (sequence: DPCGERICSIAL) M6 SCSSFLCSLKVG) with good affinity specificity virus (MPXV) B21R protein. To simulate the state peptide in avoid spatial obstacles peptide, GGGSK was added at C terminus named as M4a. Molecular docking shows that M4a are...
Abstract. A long-lived gravity wave (GW) in the atmospheric boundary layer (ABL) is analysed during a field experiment Anqing, China (30∘37′ N, 116∘58′ E). Persistent GWs with periods ranging from 10 to 30 min over h ABL within 2 km height are detected by coherent Doppler lidar 4 5 September 2018. The amplitudes of vertical wind due these approximately 0.15–0.2 m s−1. lifetimes longer than 20 cycles. There no apparent phase progression altitude. and zonal perturbations 90∘ out phase,...
Accurate wind shear detection is crucial for aviation safety, especially in landing and departure. A new approach windshear alerting proposed demonstrated. This monitors orthogonal components multiple runways using single coherent Doppler lidar (CDWL). First, the two of field are retrieved from radial speed by an updated variational method. Then, heading cross on different calculated simultaneously, without location restriction lidar. Finally, a message generated through quantitatively...
Convective weather is often accompanied by precipitation and windshear, seriously endangering the safety of aircraft during takeoff landing. However, under rainfall conditions, conventional wind lidars have a limited detection range due to significant signal attenuation. To solve this problem, 200 mm temperature-controlled telescope coated with hydrophobic film applied in coherent Doppler lidar system improve capability rain. The maximum extended 30 km demonstrated at Kunming Changshui...
The refractive index structure constant (Cn2) is a key parameter used in describing the influence of turbulence on laser transmissions atmosphere. Three different methods for estimating Cn2 were analyzed detail. A new method that uses combination these continuous profiling with both high temporal and spatial resolution proposed demonstrated. Under assumption Kolmogorov “2/3 law”, profile can be calculated by using wind field turbulent kinetic energy dissipation rate (TKEDR) measured coherent...
Accurate power spectrum analysis of weak backscattered signals are the primary constraint in long-distance coherent Doppler wind lidar (CDWL) applications. To study atmospheric boundary layer, an all-fiber CDWL with 300µJ pulse energy is developed. In principle, detection method can approach quantum limit sensitivity if noise photodetector output dominated by shot local oscillator. practice, however, abnormal spectra occur randomly, resulting error estimation and low inversion probability....
