FEASIBILITY EXPLORATION OF “MULTI-CONFORMITY” UNDER THE BACKGROUND OF BIG DATA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 “Multi-conformity” requires the unification of surveying and mapping coordinate system. The Ministry of Natural Resources calls for the unified use of CGCS2000 coordinates in natural resources systems.

Mapping the Reaction Coordinates of Enzymatic Defluorination [PDF]
Journal of the American Chemical Society, 2011 The carbon-fluorine bond is the strongest covalent bond in organic chemistry, yet fluoroacetate dehalogenases can readily hydrolyze this bond under mild physiological conditions. Elucidating the molecular basis of this rare biocatalytic activity will provide the fundamental chemical insights into how this formidable feat is achieved. Here, we present a

Derivation and application of an analytical rock displacement solution on rectangular cavern wall using the inverse mapping method. [PDF]
PLoS ONE, 2017 Rectangular caverns are increasingly used in underground engineering projects, the failure mechanism of rectangular cavern wall rock is significantly different as a result of the cross-sectional shape and variations in wall stress distributions. However,

Pushing the limits of the reaction-coordinate mapping [PDF]
The Journal of Chemical Physics, 2019 The reaction-coordinate mapping is a useful technique to study complex quantum dissipative dynamics into structured environments. In essence, it aims to mimic the original problem by means of an “augmented system,” which includes a suitably chosen collective environmental coordinate—the “reaction coordinate.” This composite then couples to a simpler ...

A Remote Sensing Method for Crop Mapping Based on Multiscale Neighborhood Feature Extraction
Remote Sensing, 2022 Obtaining accurate and timely crop mapping is essential for refined agricultural refinement and food security. Due to the spectral similarity between different crops, the influence of image resolution, the boundary blur and spatial inconsistency that ...

$n$-Harmonic coordinates and the regularity of conformal mappings [PDF]
Mathematical Research Letters, 2014 This article studies the smoothness of conformal mappings between two Riemannian manifolds whose metric tensors have limited regularity. We show that any bi-Lipschitz conformal mapping or $1$-quasiregular mapping between two manifolds with $C^r$ metric tensors ($r > 1$) is a $C^{r+1}$ conformal (local) diffeomorphism.

ANALYSIS OF COMMON QUALITY PROBLEMS IN COORDINATE TRANSFORMATION BETWEEN REFERENCE COORDINATE SYSTEM AND GEOCENTRIC COORDINATE SYSTEM [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 In the working of the existing reference coordinate system transformed into the coordinate system of the geocentric coordinate system, many experts and scholars have in-depth research on the transformation methods such as geodetic control point results ...
