New digital platforms are transforming learning in higher education and providing high-quality education content at little or no cost. Educators can now reach large, even global audiences. Yet, many medical schools continue to develop and maintain custom but duplicative...

Mechanistic studies of the dehydrocoupling and dehydropolymerization of amine-boranes using a [Rh(Xantphos)]⁺ catalyst.

Journal of the American Chemical Society

Johnson HC, Leitao EM, Whittell GR, Manners I, Lloyd-Jones GC, Weller AS.
PMID: 24844130
J Am Chem Soc. 2014 Jun 25;136(25):9078-93. doi: 10.1021/ja503335g. Epub 2014 Jun 11.

A detailed catalytic, stoichiometric, and mechanistic study on the dehydrocoupling of H3B·NMe2H and dehydropolymerization of H3B·NMeH2 using the [Rh(Xantphos)](+) fragment is reported. At 0.2 mol % catalyst loadings, dehydrocoupling produces dimeric [H2B-NMe2]2 and poly(methylaminoborane) (M(n) = 22,700 g mol(-1),...

Bayesian estimation of ventricular contours in angiographic images.

IEEE transactions on medical imaging

Teles de Figueiredo M, Leitaa JN.
PMID: 18222884
IEEE Trans Med Imaging. 1992;11(3):416-29. doi: 10.1109/42.158946.

A method for left ventricular contour determination in digital angiographic images is presented. The problem is formulated in a Bayesian framework, adopting as the estimation criterion the maximum a posterior probability (MAP). The true contour is modeled as a...

Thermal decomposition modes for four-coordinate ruthenium phosphonium alkylidene olefin metathesis catalysts.

Chemistry (Weinheim an der Bergstrasse, Germany)

Leitao EM, Dubberley SR, Piers WE, Wu Q, McDonald R.
PMID: 19035588
Chemistry. 2008;14(36):11565-72. doi: 10.1002/chem.200801584.

The four-coordinate ruthenium phosphonium alkylidenes 1-Cy and 1-iPr, differing in the substituent on the phosphorus center, were observed to decompose thermally in the presence of 1,1-dichloroethylene to produce [H(3)CPR(3)][Cl]. The major ruthenium-containing product was a trichloro-bridged ruthenium dimer that...

Complex cell prototype representation for face recognition.

IEEE transactions on neural networks

Prssoa L, Leitao AP.
PMID: 18252655
IEEE Trans Neural Netw. 1999;10(6):1528-31. doi: 10.1109/72.809099.

In this paper we propose a new face recognition system based on a biologically inspired filtering method. Our work differs from previous proposals in: 1) the multistage filtering method employed; 2) the pyramid structure used, and most importantly; 3)...
