Dispersion-Clamped Crystalline Supramolecular Columnar π-Stacks of Adamantyl-Substituted Pyrenes. [PDF]
Angew Chem Int Ed EnglCan neutral hydrocarbon π‐systems be forced into perfectly aligned cofacial stacks in crystals? An adamantyl‐decorated pyrene derivative crystallizes into rare translationally zero‐offset π‐columns, producing a short π–π distance below 3.3 Å and a large color shift arising from frontier crystal orbital (FCO) formation. ABSTRACT Despite their importance

Analysis of polarization characteristics of freeform surface optical system [PDF]
ITM Web of Conferences, 2022 Freeform surfaces are widely used in off-axis optical systems with large aperture, large field of view, and long focal length. The polarization effect caused by the non-rotationally symmetrical shape has an impact on the system’s polarization imaging ...

The Anomalously High Boiling Point of Water Revisited [PDF]
ChemistryOpenPairwise interactions between binary hydrides depend mainly on size, not dipole moment. Small hydrides experience less steric repulsion, bringing molecules closer together and strengthening hydrogen bonds, which explains their high boiling points. Typically, boiling points increase with molecular weight because dispersion forces strengthen.

Learning k-qubit Quantum Operators via Pauli Decomposition
, 2021 Motivated by the limited qubit capacity of current quantum systems, we study the quantum sample complexity of $k$-qubit quantum operators, i.e., operations applicable on only $k$ out of $d$ qubits. The problem is studied according to the quantum probably approximately correct (QPAC) model abiding by quantum mechanical laws such as no-cloning, state ...

Oil spill detection from SAR image using SVM based classification [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013 In this paper, the potential of fully polarimetric L-band SAR data for detecting sea oil spills is investigated using polarimetric decompositions and texture analysis based on SVM classifier.

A NOVEL TWO-COMPONENT DECOMPOSITION FOR CO-POLAR CHANNELS OF GF-3 QUAD-POL DATA [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 Polarimetric target decomposition theory is the most dynamic and exploratory research area in the field of PolSAR. But most methods of target decomposition are based on fully polarized data (quad pol) and seldom utilize dual-polar data for target ...

H2ZIXY: Pauli spin matrix decomposition of real symmetric matrices
, 2021 We present a code in Python3 which takes a square real symmetric matrix, of arbitrary size, and decomposes it as a tensor product of Pauli spin matrices. The application to the decomposition of a Hamiltonian of relevance to nuclear physics for implementation on quantum computer is given.
