Intrinsic graph convolution operators with differentiable kernel functions play a crucial role in analyzing 3D shape meshes. In this paper, we present fast and efficient intrinsic mesh operator that does not rely on the intricate design of function. We explicitly formulate order aggregating neighboring vertices, instead learning weights between nodes, then fully connected layer follows to fuse local geometric structure information vertex features. provide extensive evidence showing models...
A highly efficient, one-pot Fe(NO<sub>3</sub>)<sub>3</sub>/TEMPO-catalyzed protocol for aerobic oxidative synthesis of quinazolinones from easily accessible primary alcohols and 2-aminobenzamides with molecular oxygen as the terminal oxidant.
Structured-light profilometry is a powerful tool to reconstruct the three-dimensional (3D) profile of an object. Accurate acquisition often hindered by not only nonlinear response (i.e., gamma effect) electronic devices but also projection-imaging distortion lens used in system. In this paper, flexible 3D reconstruction method based on iterative optimization proposed correct errors caused distortion. It can be easily extended measurements for which more complex model required. Experimental...
During traffic data acquisition, missing often arise owing to equipment failures and network disruptions. Despite extensive research on imputation, two primary limitations persist: First, existing methods struggle fully integrate the spatiotemporal correlations low-rank structures inherent in data. Second, current has mostly focused completely at random (MCAR), with limited attention other patterns. We propose an innovative method, tensor completion graph fusion (TCGNF), address these...
Pentazolate (cyclo-N5–) salts are actively pursued energetic nitrogen-rich compounds due to their potential as propellants and explosives. An in-depth understanding of the stabilizing forces between cyclo-N5– anions cations is important for designing achieving salt conversions. Herein, metathetical syntheses (compounds 1–4) containing heterocyclic amino-based 3,6-diguanidino-1,2,4,5-tetrazine, 1-guanyl-1,2,4-triazolium, 3,7-diamino-7H-[1,2,4]triazolo[4,3-b][1,2,4]triazol-2-ium,...
To determine the absolute flatness deviations of optical surfaces, a novel method using two plates to achieve test is presented. Absolute three rear surface plate I and front surfaces II, are obtained by four measurements. Wavefront error due inhomogeneity II measured beforehand then subtracted from results. Vertical profiles compared with measurement results Zygo's three-flat application. Good agreement validates our method. The advantage that only one transmission flat needed during test,...
In this paper the conjugate differential method is proposed to measure absolute surface shape of flat mirror using a phase-shifting interferometer. The derived from method, which extracts phase differences by introducing slight transverse shifts optic. It employs measurement schemes making on orthogonally bilateral symmetry positions. So procedures have been changed into four-step tests get difference map instead three-step for method. precision slope approximation enhanced reducing...
A complete complex amplitude reconstruction method for the determination of laser beam quality factor M2 based on multiple exposure a quadriwave lateral shearing interferometer (QWLSI) is presented. The theoretical analysis and simulation influence information in small signal area calculation provided. experimental results demonstrate that new can be an accurate means to measure factor. proposed avoid phase inaccuracy interferogram, during measurement
Object image grating self-tiling reduces difficulties of obtaining an ideal tiling condition by eliminating three errors in six within a tiled grating. However, this may bring two potential problems: higher requirements adjustment accuracy and maintaining stability. To examine the application values configuration, performance object traditional configurations on stability are compared theoretically experimentally. Adjustment calculated, comparative experiment long-term stabilities is...
The all-nitrogen cyclo-pentazolate (c-N5–) anion has attracted considerable attention because of its potential applications in high-energy density materials. However, achieving comprehensive insight into the chemical properties c-N5– is challenging complex behavior. To elucidate this behavior, we stabilized by forming triaminoguanidinium (1) and 4-nitro-(3,4-diamino-1,2,4-triazolium-5-yl)-1H-pyrazolium (2) salts cocrystal (3) a 1:1 ratio 3,3-dinitroazetidinium pentazolate to...
