(Dimethyl­formamide-κO)[2-meth­oxy-6-(2-pyridylmethyl­imino­meth­yl)phenolato-κ3 N,N′,O 1](thio­cyanato-κN)copper(II)

In the title compound, [Cu(C14H13N2O2)(NCS)(C3H7NO)], the Cu2+ ion is coordinated by an N,N′,O-tridentate 2-meth­oxy-6-(2-pyridylmethyl­imino­meth­yl)phenolate ligand, an N-bonded thio­cyanate ion and an O-bonded dimethyl­formamide (DMF) mol­ecule, resulting in a distorted CuN3O2 square-based pyramidal geometry for the metal ion, with the DMF O atom in the apical site. The dihedral angle between the aromatic rings in the ligand is 8.70 (16)°. The S atom is disordered over two positions in a 0.901 (6):0.099 (6) ratio. In the crystal, mol­ecules inter­act by way of π–π stacking inter­actions [centroid–centroid separation = 3.720 (2) Å]

3D Reconstruction from IR Thermal Images and Reprojective Evaluations

Infrared thermography has been widely used in various domains to measure the temperature distributions of objects and surfaces. The methodology can be further extended to 3D applications if the spatial information of the temperature distribution is available. This paper proposes a 3D infrared imaging approach based on silhouette volume intersection to reconstruct volumetric temperature data of enclosed objects. 3D IR images are taken from various angles and integrated with 2D RGB images to effectively reconstruct a 3D model of the object's temperature distributions. Various automatic thresholding methods are also compared and evaluated by reprojection scoring to systematically assess the effectiveness and accuracy of the different approaches. Experiment results have demonstrated the ability of the system to provide an estimate to the 3D location of an internal heat source from images taken externally

Isospin dependence of nucleon effective mass in Dirac Brueckner-Hartree-Fock approach

The isospin dependence of the nucleon effective mass is investigated in the framework of the Dirac Brueckner-Hartree-Fock (DBHF) approach. The definition of nucleon scalar and vector effective masses in the relativistic approach is clarified. Only the vector effective mass is the quantity related to the empirical value extracted from the analysis in the nonrelatiistic shell and optical potentials. In the relativistic mean field theory, where the nucleon scalar and vector potentials are both energy independent, the neutron vector potential is stronger than that of proton in the neutron rich nuclear matter, which produces a smaller neutron vector effective mass than that of proton. It is pointed out that the energy dependence of nucleon potentials has to be considered in the analysis of the isospin dependence of the nucleon effective mass. In the DBHF the neutron vector effective mass is larger than that of proton once the energy dependence of nucleon potentials is considered. The results are consistent with the analysis of phenomenological isospin dependent optical potentials.Comment: 4 pages, 3 Postscript figure
