Abstract Vortex beams carry orbital angular momentum (OAM) and exhibit a ring-shaped intensity distribution, adding new dimension compared to Gaussian beams. In cloudy foggy environments, using vortex for detection imaging can partially improve the signal-to-noise ratio ( SNR ) affected by backscattering However, improvement is limited at high concentrations. We introduce novel approach of beam under these conditions. First, we utilized ring filter preliminary noise reduction, then applied...
De novo mutations (DNMs) are significant genetic factors contributing to sporadic hearing loss (HL) and complex HL syndromes. To analyze the counseling characteristics interpretation of pathogenic DNMs for HL, we retrospectively clinical information probands their parents from 410 core pedigrees enrolled in "Chinese Deafness Genome Project (CDGP)" between October 2015 2023. We apply family trio-based genome sequencing (targeted gene capture high throughput sequencing, mitochondrial copy...
One-dimensional (1D) perovskite heterostructures fabricated through the template method employing single-walled carbon nanotubes (SWCNTs) have garnered significant attention due to their distinctive structural properties. Nevertheless, substantial challenges remain in device applications of 1D halide separation issue semiconductor SWCNTs (s-SWCNTs) after encapsulating perovskite. Here, we report based on CsPbBr3 encapsulated inside s-SWCNTs (CPB@s-SWCNTs), realizing editable photoresponse....
Laser-induced periodic surface structures (LIPSS) are a universal phenomenon that can allow tailoring nanoelectronics and nanophotonics devices. However, there is an issue about the formation mechanism of LIPSS, current research mainly focuses on process individual structures, such as low spatial frequency LIPSS (LSFL), sub-wavelength laser-induced annular (LIPASS). A whole picture series these still missing. In this study, pump-probing setup applied to ensure real-time in situ monitoring...
In detecting the rotation velocity of an object employing rotational Doppler effect vortex beams, atmospheric turbulence can easily cause phase distortion and spiral spectrum dispersion, consequently reducing measurement accuracy. This study combines adaptive optical intelligence algorithms with polarization compensation information to propose a novel approach, Stokes–Particle swarm optimization Gerchberg–Saxton (Stokes-PSO GS) algorithm, which integrates Stokes assistance PSO for GS...
Femtosecond laser pulse of 800 nm wavelength and 150 fs temporal width ablation As₂S₃ chalcogenide glasses is investigated by pump-probing technology. At lower fluence (8.26 mJ/cm²), the surface temperature dropping to melting point fast (about 43 ps), which results in a clean hole on surface. As increases, it takes longer time for lattice cool at high 200 ps 18.58 mJ/cm², about 400 30.98 mJ/cm²). The heating induces pool center, accelerates material diffusing gathering surrounding crater,...
The measurement of the rotational velocity using Doppler effect (RDE) a vortex beam is easily affected by atmospheric turbulence, leading to dispersed orbital angular momentum (OAM), and reduced accuracy. This study investigates optimal ability Gerchberg-Saxton (GS) phase retrieval algorithm compensate for optical field enhance accuracy within range intrinsic parameters, such as number GS iterations, extrinsic turbulence intensity properties. Through detailed theoretical simulation analyses,...
Two-photon fluorescence imaging has shown a promising application in biomedical due to its outstanding advantages such as large penetration depth, low photo-damage, and photo-bleaching, etc. Among them, the two-photon fluorescent dye NAPBr, which can effectively select monitor lipid droplets living cells biological tissues, attracted extensive attention because of excellent properties. However, research on abilities dyes solvent environment is not sufficient. In our work, theoretical...
In measuring object rotational velocity using vortex beam, the incident light on a tilted causes spectral broadening, which significantly interferes with identification of true Doppler shift (RDS) peak. We employed decomposition method to analyze relationship between extremum and central frequency caused by tilt. Compared linear growth trend observed when calculating peak maximum amplitude, calculation effectively reduced deviation rate RDS measurement value from value, even at large tilt...
Abstract Traditional methods for extracting and recognizing targets from laser echo signals typically involve complex processing require extensive data. Vortex beams carry orbital angular momentum (OAM), upon reflection a target, the distribution of OAM spectrum carries features related to thereby enriching dimensions target recognition. Using simplifies recognition process but faces challenges like atmospheric turbulence that affect beam transmission accuracy. Our study employs...
Nowadays, as the development of AI (Artificial Intelligence), artificial neural network has applied for reservoir prediction many years one branch AI. Deep marine carbonate rocks in western Sichuan have a large gas resources and its good exploration prospects. However, most is buried deep ground at present (almost over 5700 meters), with characteristics including weak seismic pore fluid response, little difference between non-reservoir, leading to detection becoming difficult. In order get...
