Branko Furst’s Radical Alternative

“Most heart failure trials yield results that are disappointing or difficult to interpret,” Milton Packer, MD, wrote in the April 2016 issue of Circulation: Heart Failure.1 Dr. Packer, Distinguished Scholar in Cardiovascular Science at Baylor University Medical Center in Dallas, has experienced this frustration firsthand as lead investigator of more than 15 large international multicenter heart...

Copic Evidence for an Iron - Chlorin Prosthetic

The green heme protein sulfmyoglobin (SMb) has been suggested to contain a sulfur-modified iron chlorin prosthetic group. To evaluate this hypothesis, we have obtained high-frequency (71000 cm”) resonance Raman spectra of both oxidized and reduced SMb with 457.9-, 488.0-, 5 1 4 5 , 568.2-, and 647.1nm excitation. The SMb spectra are compared to those of native metand deoxymyoglobin (Mb). Vib...

Improving Writer Identification Through Writer Selection

In this work we present a method for selecting instances for a writer identification system underpinned on the dissimilarity representation and a holistic representation based on texture. The proposed method is based on a genetic algorithm that surpasses the limitations imposed by large training sets by selecting writers instead of instances. To show the efficiency of the proposed method, we ha...

Hybrid writer-independent-writer-dependent offline signature verification system

Standard signature verification (SV) systems are writer-dependent (WD), where a specific classifier is designed for each individual. It is inconvenient to ask a user to provide enough number of signature samples to design his WD classifier. In practice, very few samples are collected and inaccurate classifiers maybe produced. To overcome this, writer-independent (WI) systems are introduced. A g...
