The jellyfish search (JS) algorithm impersonates the foraging behavior of in ocean. It is a newly developed metaheuristic that solves complex and real-world optimization problems. global exploration capability robustness JS are strong, but still has significant development space for solving problems with high dimensions multiple local optima. Therefore, this study, an enhanced (EJS) developed, three improvements made: (i) By adding sine cosine learning factors strategy, can learn from both...
Abstract Using the Gaussian‐Schell model (GSM) beam as light source, this study creates a blue‐green atmosphere‐ocean cross‐medium propagation (AOCPM) based on extended Huygens‐Fresnel principle and linear filtering method. The closed expression of Cross Spectral Density Function (CSDF) GSM after through atmospheric turbulence, interface, ocean turbulence are derived. And correctness is verified by simulating changes in intensity, relative width, speckle normalized intensity autocorrelation...
The association between gut microbiota and development of Graves' disease (GD) remains unclear. This study aimed to profile the 65 patients newly diagnosed with GD before after treatment 33 physical examination personnel via 16S rRNA sequencing. Significant differences in composition were observed two groups, showing relative bacterial abundances 1 class, order, 5 families, 14 genera. After treatment, abundance significantly enriched biota group decreased considerably, whereas that...
Vortex beams with orbital angular momentum (OAM) significantly enhance system capacity, and high-precision recognition of OAM mode through atmospheric turbulence (AT) channels can markedly improve the information transmission capability free-space optical communication systems. In this paper, a cylindrical lens-assisted distinguish between positive negative OAM, reliable neural network combining multi-scale dilated convolution (MSDC) unit multi-level feature fusion (MLFF) module is proposed...
Abstract The properties of BaTiO 3 and the electronic structure H 2 O adsorption on were investigated by using first principle calculations based density functional theory. calculated results show that orbital hybridization between Ti is stronger than Ba O. With increase energy, reflex points in form random fluctuation anisotropy crystal clear. Enthalpy heat capacity varies with temperature rise, while free energy fall. bonds are formed hydrogen water surface oxygen hydroxyl . process...
The species Prunus mume consists of uniquely aromatic woody perennials with large amounts free substances in the flower cells. Uridine diphosphate glycosyltransferase (UGT) modifies these into water-soluble glycoside-bound volatiles (GBVs) which play an important role regulating use by plants for information exchange, defense, and stress tolerance. To investigate changes glycosidic state during flowering period P. discern location expression glycoside synthesis genes, we extracted...
Considering the shortcomings of existing clustering algorithms in quality, this paper proposes a load research based on singular value decomposition and K-means algorithm. First, eight characteristic indexes are extracted, is used to decompose characteristics user side. The solved reflects importance type characteristic. corresponding data with large taken as main complete dimensionality reduction data. Then, evaluation index SSE compare effects direct after decomposition. results show that...
In this paper, we introduce a vortex class of partially coherent source Schell type with an electromagnetic Gaussian Schell-model (EGSMV) beam, which is the product EGSM beam passing through spiral phase modulator. The analytical expressions for degree polarization (DoP) and orientation angle (OAoP) EGSMV propagating atmospheric turbulence are derived. used to analyze influence topological charge, wavelength, on DoP OAoP come some new conclusions. larger charge is, bigger dark spot in center...
Volume estimation is a fundamental problem in the morphometric study of impact craters. The Top Hat Transform function (TH), gray-level image processing technique has already been applied to Digital Elevation Model (DEM) extract peaks and pits nonuniform background. In this study, an updated Black (BTH) was quantify volume lunar craters on Moon. We proposed iterative BTH (IBTH) where window size slope factor were linearly increased different sizes, along with novel application automatically...
Maksutov-Cassegrain (MC) systems are widely used in long-range free-space optical (FSO) communication. In this study, analytical expressions for the diffraction field of a Laguerre-Gaussian (LG) beam passing through an MC system have been derived. The numerical results reveal that, FSO system, replacement Gaussian by LG enhances emission efficiency MC. Furthermore, has shaping effect on beam, and orbital angular momentum is not dispersed when diffracted
In this article, we take partially coherent electromagnetic Gaussian-Schell model (EGSM) beam as a research object. Based on the unified theory of coherence and polarization generalized Stokes parameters random beams, expressions degree (DoP) orientation angle EGSM that propagates in slant atmospheric turbulence, are derived. And used to investigate difference property between propagating along an uplink path downlink turbulence. The results show under same conditions, DoP distribution is...
