Carbon dots (CDs) obtained from rapeseed pollen with a high production yield, good biocompatibility, water solubility, low cost, and simple synthesis are systematically characterized. They can be directly added to Hoagland nutrient solution for planting hydroponically cultivated Lactuca sativa L. explore their influence on the plants at different concentrations. By measuring lettuce indices of growth, morphology, nutrition quality, gas exchange, content photosynthetic pigment, amazing...
Orbital angular momentum (OAM) multiplexing has emerged as an important method to increase the communication capacities in future optical information technologies.In this work, we demonstrate a silicon integrated OAM (de)multiplexer with very simple structure.By simply tapping evanescent wave of two different whispering gallery modes rotating inside multimodal micro-ring resonator, four in-plane waveguide are converted free-space vector beams high mode purity.We further chip-to-chip...
We demonstrate a microelectromechanical-system-based tunable grating coupler capable of changing the central wavelength. The structure is fabricated on suspended cantilever with supporting arms and can be tuned by an applied voltage. range 22.8 nm under actuation voltages up to 12 V in present devices. In addition, we show that are critical components used effectively avoid pull-in effect.
Ultradrawing and ultimate tensile properties of ultrahigh molecular weight polyethylene (UHMWPE) composite fibers were successfully improved by the addition nanoalumina (NAL), acid treated (ATNAL), and/or functionalized (FNAL). As evidenced FTIR TEM analyses, maleic anhydride grafted (PEg-MAH) molecules onto ATNAL fillers. The specific surface areas FNAL fillers reached a maximal value at 516 m2/g, as they modified using an optimal ratio PEg-MAH to 8. Achievable draw (Dra) values UHMWPE/NAL...
Integrated devices that emit light beams with orbital angular momentum (OAM) are becoming key components for wide-ranging applications. Here we propose and demonstrate a highly directional silicon photonic vortex beam emitter based on 3-turn Archimedean spiral adiabatic waveguide integrated an grating. Such compact is capable of generating small divergence angles high directivity. Various orders OAM modes can be selectively generated by the at different wavelengths side-mode suppression...
We study the dynamics of phase synchronization in growing populations discrete oscillatory systems when division process is coupled to distribution oscillator phases. Using mean-field theory, linear-stability analysis, and numerical simulations, we demonstrate that coupling between population growth synchrony can lead a wide range dynamical behavior, including extinction synchronized oscillations, emergence asynchronous states with unequal state (phase) distributions, bistability or two...
This paper presents an electrochemical–thermal–hydraulic–mechanical (ETHM) coupling model by introducing the electrolyte flow field into of lithium-ion batteries (LIBs). First, ETHM is established on basis electrochemical–thermal–mechanical (ETM) and poroelasticity model. Then, for discharge LIBs numerically resolved verified against ETM using commercial 11.5 Ah LiMn2O4 battery as example. Subsequently, deformation characteristics (such Darcy's velocity, pore pressure, Péclet number,...
The current concept semantic similarity calculation based on ontology does not take full advantage of the information. In this paper we will present a new algorithm deviding into two parts: one is name calculation, degree and edit distance calculation. other property object data Thus obtain actual according to an integrated analysis. experimental results indicate that, compared with algorithms, method can make use information, better match result.
Purpose: To investigate the effect of syphilis infection on microstructure white matter (WM) in HIV-infected male patients using diffusion tensor imaging (DTI). Methods: Twenty-seven with current or a history (HIV +/syphilis +), twenty-nine without co-infection +/syphilis–), and healthy controls (HC) were enrolled. All participants received DTI, all comprehensive neuropsychological assessment. Tract-based spatial statistics (TBSS) was adopted to analyze DTI measures: fractional anisotropy...
In this work we demonstrate chip-to-chip orbital angular momentum (OAM) multiplexing transmission using a pair of ultra-compact silicon integrated (de)multiplexer. Four OAM beams were multiplexed and then demultiplexed by the devices.

This study aimed to identify warning thresholds that can guide sellers in achieving reasonable profits while reducing buyer payment costs. Monthly price data from January 2009 June 2023 and the two-regime threshold regression model were used for an empirical analysis of asymmetric effects changes household consumption under different pork fluctuation levels verify have significant effects. It was found as prices approached threshold, temporary price-intervention policy (e.g., reference...
The effect of the iPP content on crystallisation, dynamic mechanical relaxation behavior and properties for high density polyethylene/isotactic polypropylene (HDPE/iPP) was investigated. It found that crystallinity HDPE decreased while increased with increase content. Two relaxations, namely, γ associated amorphous phase α at positive temperature related to crystalline were detected, respectively. HDPE/iPP blending monofilaments shifted a higher remained unaffected raising component....
