Digital substations are essential components of the smart grids of the future. Advanced operation and control strategies should be implemented there by acting on data in a digital form. However, the data quality hugely depends on the input analog signals sourced from instrument transformers. Although considerable efforts have been made to improve their operation, many problems still remain unsolved...

Mortality salience effects on reckless driving intentions in a motorcyclist sample: The moderating role of group riding

Igor Ivanov, Tobias Vogel

European Journal of Social Psychology > 47 > 1 > 92 - 96

Campaigns against reckless driving often mention the risk of dying. Research on terror management theory indicates that death claims may backfire and foster reckless driving. Here, we studied such mortality salience effects in a motorcyclist sample. Two moderating variables, particularly interesting regarding the sample of motorcyclists, were considered: group riding (vs. riding alone) and driving‐related...

Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids > 2016 > 1861 > 11 > 1681-1692

Pseudomonas aeruginosa expresses a secreted LOX-isoform (PA-LOX, LoxA) capable of oxidizing polyenoic fatty acids to hydroperoxy derivatives. Here we report high-level expression of this enzyme in E. coli and its structural and functional characterization. Recombinant PA-LOX oxygenates polyenoic fatty acids including eicosapentaenoic acid and docosahexaenoic acid to the corresponding (n-6)S-hydroperoxy...

Synchrophasor-based transmission line parameter estimation algorithm taking into account measurement errors

Igor Ivanov, Andrey Murzin

2016 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe) > 1 - 6

2016 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe)

The topic of overhead transmission line parameter estimation has recently been of much interest to power system engineers worldwide. Although a decently large volume of papers on this topic has come out, only a small percentage of them try to simulate real-world scenarios when estimating the line parameters. As a result, the developed algorithms might be of little practical utility. This paper describes...

Processes and Tools for Co Alloy Capping

Bill Lee, Igor Ivanov

Advanced Nanoscale ULSI Interconnects: Fundamentals and Applications > Electrochemical Processes and Tools > 445-457

The copper Damascene process is widely established and has brought higher performance to semiconductor devices. Copper has replaced aluminum because of its lower resistivity, higher reliability, and lower cost and was expected to be better because of its higher activation energy for diffusion. However, copper also suffers from electromigration (EM) and stress migration (SM) reliability issues (Fig...

Igor Ivanov, Hartmut Kuhn, Dagmar Heydeck

Gene > 2015 > 573 > 1 > 1-32

Lipoxygenases (LOX) form a family of lipid peroxidizing enzymes, which have been implicated in a number of physiological processes and in the pathogenesis of inflammatory, hyperproliferative and neurodegenerative diseases. They occur in two of the three domains of terrestrial life (bacteria, eucarya) and the human genome involves six functional LOX genes, which encode for six different LOX isoforms...

We have described a rare case of Takotsubo cardiomyopathy in pregnancy, which is presented with cardiac arrest (ventricular fibrillation) at onset. In this case, the transient left ventricular ballooning in absence of coronary artery disease, produced a severe impairment of cardiac function with typical echocardiographic and electrocardiographic findings. There were complications in the form of ventricular...

Almerinda Di Venere, Eleonora Nicolai, Igor Ivanov, Enrico Dainese, more

BBA - Molecular and Cell Biology of Lipids > 2014 > 1841 > 1 > 1-10

Lipoxygenases (LOXs) are lipid-peroxidizing enzymes that are involved in the metabolism of polyunsaturated fatty acids. Their biological activity includes a membrane binding process whose molecular details are not completely understood. The mechanism of enzyme–membrane interactions is thought to involve conformational changes at the level of the protein tertiary structure, and the extent of such alterations...

Molecular basis for the catalytic inactivity of a naturally occurring near-null variant of human ALOX15

Thomas Horn, Igor Ivanov, Almerinda Di Venere, Kumar Reddy Kakularam, more

BBA - Molecular and Cell Biology of Lipids > 2013 > 1831 > 12 > 1702-1713

Mammalian lipoxygenases belong to a family of lipid-peroxidizing enzymes, which have been implicated in cardiovascular, hyperproliferative and neurodegenerative diseases. Here we report that a naturally occurring mutation in the hALOX15 gene leads to expression of a catalytically near-null enzyme variant (hGly422Glu). The inactivity may be related to severe misfolding of the enzyme protein, which...
