Solving an Avionics Real-Time Scheduling Problem by Advanced IP-Methods

We report on the solution of a real-time scheduling problem that arises in the design of software-based operation control of aircraft. A set of tasks has to be distributed on a minimum number of machines and offsets of the tasks have to be computed. The ta ...

Study and simulation of different scanning strategies in SLM

Rémy Glardon, Jamasp Jhabvala, Eric Boillat, Thibaud Antignac

In the SLM process, one has to balance between power and scan speed. When small scan speed is used, thermal gradients are important and local solidification can lead to cracks. On the other hand, when high speed is used, the power has to be huge and phenom ...

Improvement of elevated temperature mechanical properties of Cu–Ni–Sn–Pb alloys

Andreas Mortensen, Vincent Laporte, Doris Empl

Cu-Ni-Sn alloys with Pb additions exhibit high mechanical strength at room temperature coupled with good machinability but experience a significant ductility loss above the melting point of lead. We explore here the influence of minor additions of Al, Mn, ...

Alterations of the 5 ' Untranslated Region of SLC16A12 Lead to Age-Related Cataract

PURPOSE. Knowledge of genetic factors predisposing to age-related cataract is very limited. The aim of this study was to identify DNA sequences that either lead to or predispose for this disease. ...

Synthesis of 3-(1,2,3-triazol-1-yl)- and 3-(1,2,3-triazol-4-yl)-substituted pyrazolo[3,4-d]pyrimidin-4-amines via click chemistry: potential inhibitors of the Plasmodium falciparum PfPK7 protein kinase

Efficient routes to 3-(1,2,3-triazol-1-yl)- and 3-(1,2,3-triazol-4-yl)pyrazolo[3,4-d]pyrimidin-4-amines using a one-pot two-step reaction are presented. The two routes give easy access to two different isomers of 1,4-disubstituted triazoles and the target ...

High-Strain Lead-free Antiferroelectric Electrostrictors

Dragan Damjanovic

Research on lead-free piezoceramics has dramatically increased over the last years due to stringent legislation demanding to phase out current lead- containing piezoceramics. The use of electrostrictive materials for electric-field induced strain has been ...

About the Electrospray Ionization Source in Mass Spectrometry: Electrochemistry and On-chip Reactions

Hubert Girault, Niels Erik Lion, Christophe Roussel, Manuel Alejandro Méndez Agudelo, Michel Prudent, Joël Stéphane Rossier, Bin Su

The present work shows that the electrochemical properties of electrospray ionization (ESI) can be used to add functions to the process. As example, we show how the choice of the electrode material can be used to study interactions between metal ions and b ...

The cyanobacterial alkaloid nostocarboline: an inhibitor of acetylcholinesterase and trypsin

Karl Gademann

Preselected cyanobacterial strains (available from culture collections and our own isolates), belonging primarily to the heterocystous cluster, were screened for inhibitors against butyrylcholinesterase. About one-half of the extracts exhibited inhibitory ...

Comment on 'An analytic solution of capillary rise restrained by gravity' by N. Fries and M. Dreyer

David Andrew Barry, Laurin Wissmeier

The porous medium model of Green and Ampt, describing flow in porous media, appeared earlier than the capillary model of Washburn, although both lead to the mathematically identical models. The model of Green and Ampt is related to the Washburn model by an ...

Factorization of quantum charge transport for noninteracting fermions

Dmitri Ivanov

We show that the statistics of the charge transfer of noninteracting fermions through a two-lead contact is generalized binomial at any temperature and for any form of the scattering matrix: an arbitrary charge-transfer process can be decomposed into indep ...
