Universal Coherence-Induced Power Losses of Quantum Heat Engines in Linear Response. [PDF]
Physical Review Letters, 2017 We identify a universal indicator for the impact of coherence on periodically driven quantum devices by dividing their power output into a classical contribution and one stemming solely from superpositions.

A Novel Decomposition for Control of DC Circuits and Grid Models with Heterogeneous Energy Sources [PDF]
, 2017 The way in which electric power depends on the topology of circuits with mixed voltage and current sources is examined. The power flowing in any steady-state DC circuit is shown to depend on a minimal set of key variables called fundamental node voltages

MYCN Amplification in RB1‐Inactivated Retinoblastoma: Association With High‐Risk Features
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background MYCN amplification occurs in a subset of retinoblastoma cases, both with and without RB1 inactivation. It has been suggested that retinoblastomas with MYCN amplification represent a distinct entity with more aggressive clinical behavior.
