Identifying the spatial heterogeneity characteristics of ecosystem services (ESs) and their influencing mechanisms is crucial for regional ecological management sustainable development. This study quantified net primary production (NPP), water yield (WY), soil conservation (SC), sand fixation (SF), habitat quality (HQ) total service (TES) on Qinghai Tibet Plateau (QTP), then analyzed spatial–temporal ESs. The geographical detector model (GDM), geographically weighted regression (GWR) model,...
Directional light scattering is important in basic research and real applications. This area has been successfully downscaled to wavelength subwavelength scales with the development of optical antennas, especially single-element nanoantennas. Here, by adding an auxiliary resonant structure a plasmonic nanoantenna, we show that highly efficient lowest-order antenna mode can be effectively transferred into inactive higher-order modes. On basis this conversion, scattered fields well manipulated...
Inverse design arises in a variety of areas engineering such as acoustic, mechanics, thermal/electronic transport, electromagnetism, and optics. Topology optimization is major form inverse design, where we optimize designed geometry to achieve targeted properties the parameterized by density function. This challenging, because it has very high dimensionality usually constrained partial differential equations (PDEs) additional inequalities. Here, propose new deep learning method --...

Abstract A new multifunctional apparatus was developed to generate various magnetic fields using a single coil loop, two loops (i.e., Helmholtz coil), three loops, and long straight solenoid. The field formulas were derived based on the Biot-Savart law principle of superposition fields. experimental results achieved good agreement with theoretical predictions, an error less than 10.0%。 This compact is suitable for both teaching in college physics.
Abstract Spatially incoherent light sources, such as spontaneously emitting atoms, naively require Maxwell’s equations to be solved many times obtain the total emission, which becomes computationally intractable in conjunction with large-scale optimization (inverse design). We present a trace formulation of emission that can efficiently combined inverse design, even for topology over thousands design degrees freedom. Our includes previous reciprocity-based approaches, limited few output...
The source regions of the Yellow River and Yangtze in central-eastern part Tibetan Plateau. Hydrological model is an important tool simulation watershed hydrology. However, as more basic geographic data becomes publicly available shared globally, researchers are developing a 'symptom' difficulty choosing data, so systematic comparative analysis for input selection necessary. We tested effects different types, sources, resolutions on output results based SWAT model, focused mechanism role how...

Abstract Launching the free-space light to surface plasmon polaritons (SPPs) in a broad bandwidth is of importance for future plasmonic circuits. Based on interference pure SPP component, bandwidths unidirectional launching difficult be further broadened. By greatly manipulating intensities with quasi-cylindrical waves (Quasi-CWs), an ultra-broadband launcher experimentally realized submicron asymmetric slit. In nano-groove slit, excited Quasi-CWs are not totally damped and they can...
The low efficiency of Raman spectroscopy can be overcome by placing the active molecules in vicinity scatterers, typically rough surfaces or nanostructures with various shapes. This surface-enhanced scattering (SERS) leads to substantial enhancement that depends on scatterer is used. In this work, we find fundamental upper bounds for arbitrary-shaped depending only its material constants and separation distance from molecule. According our metric, silver optimal visible wavelengths while...
