Heating behavior of magnetic iron oxide nanoparticles at clinically relevant concentration

Lemal, Philipp ; Balog, Sandor ; Geers, Christoph ; Taladriz-Blanco, Patricia ; Palumbo, Andrea ; M.Hirt, Ann ; Rothen-Rutishauser, Barbara ; Petri-Fink, Alke

In: Journal of Magnetism and Magnetic Materials, 2019, vol. 474, p. 637–642

Magnetic hyperthermia for cancer treatment has gained significant attention in recent years, due to its biocompatibility of applied nanoparticles and the possibility for spatially localized heating in deep tissues. Clinical treatments use nanoparticle concentrations of 112 mg Fe/mL, while the concentrations experimental studies have addressed are considerably smaller, usually between 0.1...

Seeking the roots of entrepreneurship: Insights from behavioral economics

Åstebro, Thomas ; Herz, Holger ; Nanda, Ramana ; Weber, Roberto A.

In: Journal of Economic Perspectives, 2014, vol. 28, no. 3, p. 49-70

There is a growing body of evidence that many entrepreneurs seem to enter and persist in entrepreneurship despite earning low risk-adjusted returns. This has lead to attempts to provide explanations—using both standard economic theory and behavioral economics—for why certain individuals may be attracted to such an apparently unprofitable activity. Drawing on research in behavioral economics,...

Nonequilibrium phase behavior from minimization of free power dissipation

Krinninger, Philip ; Schmidt, Matthias ; Brader, Joseph M.

In: Physical Review Letters, 2016, vol. 117, no. 20, p. 208003

We develop a general theory for describing phase coexistence between nonequilibrium steady states in Brownian systems, based on power functional theory [M. Schmidt and J. M. Brader, J. Chem. Phys. 138, 214101 (2013)]. We apply the framework to the special case of fluid-fluid phase separation of active soft sphere swimmers. The central object of the theory, the dissipated free power, is...

New insights into the lifestyle of Allosaurus (Dinosauria: Theropoda) based on another specimen with multiple pathologies

Foth​, Christian ; Evers, Serjoscha W. ; Pabst, Ben ; Mateus, Octávio ; Flisch, Alexander ; Patthey, Mike ; Rauhut, Oliver W.M.

In: PeerJ, 2015, vol. 3, p. e940

Adult large-bodied theropods are often found with numerous pathologies. A large, almost complete, probably adult Allosaurus specimen from the Howe Stephens Quarry, Morrison Formation (Late Kimmeridgian–Early Tithonian), Wyoming, exhibits multiple pathologies. Pathologic bones include the left dentary, two cervical vertebrae, one cervical and several dorsal ribs, the left scapula, the left...

Enhancing positive development of children : Effects of a multilevel randomized controlled intervention on parenting and child problem behavior

Cina, Annette ; Röösli, Martin ; Schmid, Holger ; Lattmann, Urs Peter ; Fäh, Barbara ; Schöneneberger, Michaela ; Kern-Scheffelt, Walter ; Randall, Ashley K. ; Bodenmann, Guy

In: Family Science, 2011, vol. 2, no. 1, p. 43-57

Parent-oriented and school-oriented programs that aim to improve child behavior and mental health are well established, few studies focus on the possibility of additional benefits arising from a combined intervention. This study uses a randomized control trial and assesses whether the combination of two standardized evidence-based intervention programs, Triple P (a self-directed...
