چکیده
Abstract A new compound ( 1 ) formed by two antiparallelly disposed tetracyano thienoquinoidal units has been synthesized and studied electrochemistry, UV/Vis‐NIR, IR, EPR, transient spectroscopy. Self‐assembly of on a Au(111) surface investigated scanning tunneling microscopy. Experiments have rationalized quantum chemical calculations. exhibits unique charge distribution in its anionic form, with gradient yielding neat molecular in‐plane electric dipole momentum, which transforms out‐of‐plane after deposition due to twisted→folded conformational change partial transfer from Au(111). Intermolecular van der Waals interactions antiparallel trapezoidal shape fitting lead the formation an optimal dense two‐dimensional assembly .

Fusion and display of 3D SPECT and MR images registered by a surface fitting method
Since 3D medical images such as SPECT and MRI are taken under different patients positioning and imaging parameters, interpretation of them, as reconstructed originally, does not provide an easy and accurate understanding of similarities and differences between them. The problem becomes more crucial where a clinician would like to map accurately region of interest from one study to the ot...
متن کاملCylindrical Surface Reconstruction by Fitting Paths on Shape Space
We present a differential geometric approach for cylindrical anatomical surface reconstruction from 3D volumetric data that may have missing slices or discontinuities. We extract planar boundaries from the 2D image slices, and parameterize them by an indexed set of curves. Under the SRVF framework, the curves are represented as invariant elements of a nonlinear shape space. Differently from sta...
متن کاملBayesian closed surface fitting through tensor products
Closed surfaces provide a useful model for 3-d shapes, with the data typically consisting of a cloud of points in R. The existing literature on closed surface modeling focuses on frequentist point estimation methods that join surface patches along the edges, with surface patches created via Bézier surfaces or tensor products of B-splines. However, the resulting surfaces are not smooth along the...

15 صفحه اولAnalytical Solution for a Two-Layer Transversely Isotropic Half-Space Affected by an Arbitrary Shape Dynamic Surface Load
The dynamic response of a transversely isotropic, linearly elastic layer bonded to the surface of a half-space of a different transversely isotropic material under arbitrary shape surface loads is considered. With the help of displacements and stresses Green’s functions, an analytical formulation is presented for the determination of the displacements and stresses at any point in both surface l...
