PMID: 27164588
IEEE Trans Image Process. 2016 Jul;25(7):3087-98. doi: 10.1109/TIP.2016.2561406. Epub 2016 May 02.

Magnetic resonance (MR) imaging is vulnerable to a variety of artifacts, which potentially degrade the perceived quality of MR images and, consequently, may cause inefficient and/or inaccurate diagnosis. In general, these artifacts can be classified as structured or unstructured...

Chemistry. 2016 Feb;22(6):2051-2059. doi: 10.1002/chem.201503315. Epub 2016 Jan 07.

Self-assembly driven by crown ether complexation of zinc phthalocyanines equipped with one 18-crown-6 moiety and fullerenes bearing an ammonium head group afforded a novel donor-acceptor hybrid. In reference experiments, fullerenes containing a Boc-protected amine functionality have been probed. The...

Oxidative Decomplexation of Chromium Fischer Carbene Complexes Induced by Dioxiranes.

The Journal of organic chemistry

Gibert M, Ferrer M, Lluch AM, Sánchez-Baeza F, Messeguer A.
PMID: 11674223
J Org Chem. 1999 Mar 05;64(5):1591-1595. doi: 10.1021/jo982065e.

The reaction course of the oxidative decomplexation of Fischer carbene complexes with dioxiranes was examined. The portionwise addition of 2.2 equiv of dimethyldioxirane (DMD) to Fischer carbene complex 1 afforded ethyl phenylpropiolate in 90% yield. When the reaction was...

Equilibria between metallosupramolecular squares and triangles with the new rigid linker 1,4-bis(4-pyridyl)tetrafluorobenzene. Experimental and theoretical study of the structural dependence of NMR data.

Inorganic chemistry

PMID: 12971757
Inorg Chem. 2003 Sep 22;42(19):5890-9. doi: 10.1021/ic034489j.

The new fluorinated rigid ligand L, 1,4-bis(4-pyridyl)tetrafluorobenzene, was used in combination with different diphosphine Pd(II) and Pt(II) triflates to build metallosupramolecular assemblies. Complex equilibria between triangular and square entities were detected for all the cases. Characterization of the equilibria...

IEEE Trans Med Imaging. 1988;7(4):368-80. doi: 10.1109/42.14521.

The theoretical information content, defined by C.E. Shannon (1948), is proposed as an objective measure of MR (magnetic resonance) image quality. This measure takes into account the contrast-to-noise ratio (CNR), scan resolution, and field of view. It is used...
