Travel-time prediction constitutes a task of high importance in transportation networks, with web mapping services like Google Maps regularly serving vast quantities travel time queries from users and enterprises alike. Further, such requires accounting for complex spatiotemporal interactions (modelling both the topological properties road network anticipating events -- as rush hours that may occur future). Hence, it is an ideal target graph representation learning at scale. Here we present...
ZnO@CdS heterostructure prepared by solvothermal method was used to fabricate visible-light photodetector which showed better photon sensing property than the pristine CdS nanowires based device.
Dissipative solitons emerge as stable pulse solutions of nonintegrable and nonconservative nonlinear physical systems, owing to a balance nonlinearity, dispersion, loss/gain.A considerable research effort has been dedicated characterizing amplitude phase evolutions in the spatiotemporal dynamics dissipative emerging from fiber lasers.Yet, picture buildup process lasers is incomplete absence corresponding information about polarization evolution.Here, we characterize probabilistic...
Although deep neural networks (DNNs) have achieved great success in pansharpening, most of them lack transparency and interpretability. Currently, some DNNs methods utilize unfolding techniques to alleviate this problem. However, they do not consider the regularization term separately when solving energy function that represents image degradation process, making it difficult extract complex prior information module. Therefore, paper proposes a pansharpening method based on non-local...
Various technical issues are addressed in the frequency- and time-domain finite element analysis of complex antennas arrays that may consist fine structures composite materials. The paper starts with formulation a generic antenna problem. Formulation for modeling general electrically magnetically dispersive, lossy, anisotropic materials is presented first time. This followed by discussion three typical techniques truncation computational domain via use absorbing boundary conditions,...
Cytoplasmic projections (CPs) formed by the generative and sperm cells link male gametes with vegetative cell (VC) nucleus, which are required to build germ unit (MGU) assemblage in angiosperm pollen grain. As molecular genetic controls underlying CP development formation of MGU unknown, it was hypothesized that physical association between VC nucleus might be lost
MicroRNAs (miRNAs) play an important role in plant resistance to pathogen infections. However, little is known about the of miRNAs banana Fusarium wilt, which most economically devastating disease production. In present study, we identified and characterized a total 18 miR169 family members (Musa acuminata L.) based on small RNA sequencing. The clustered into two groups miRNA evolutionary analysis. Multiple sequence alignment indicated high degree conservation miRNA169 across 28 species....
Banana is a major fruit crop grown in tropical and subtropical regions worldwide. Among cultivars, “FenJiao, FJ” ( Musa spp. ABB, Pisang Awak subgroup) popular variety of bananas, due to its better sugar-acid blend relatively small shape. However, because the traditional FJ grows high height, it vulnerable lodging unsuitable for harvesting. In this study, we sought desirable banana mutants by carrying out ethyl methanesulfonate (EMS) mutagenesis with cultivar. After shoot tips had been...
The statistical dynamics of partially incoherent ultrafast lasers are complex and chaotic, which is significant for fundamental research practical applications. We experimentally theoretically reveal the spectral evolutions correlations in an noise-like rectangle pulse laser (NLRPL). Based on histogram analysis, probability distribution asymmetry intensity fluctuation decayed with wavelength far away from peak due to detection noise. full-spectral correlation values indicate that similarity...
