Universal features in the efficiency of ultra hot quantum Otto engines

, 2014
We study internal work optimization over the energy levels of a generic hot quantum Otto engine. We find universal features in the efficiency that resembles the classical external power optimization over the coupling times to the thermal baths.

Managed decline: Muddling through with the Sterling (dis)Agreements, 1968–74

The Economic History Review, EarlyView.
Abstract How do policymakers manage the decline of an international currency? This paper revisits the view that the ‘Sterling Agreements’ of 1968–74 – bilateral contracts between the UK and sterling‐holding governments – marked a successful paradigm shift towards sterling's managed ‘retirement’.

Near-threshold Photoproduction of Phi Mesons from Deuterium

, 2010
We report the first measurement of the differential cross section on $\phi$-meson photoproduction from deuterium near the production threshold for a proton using the CLAS detector and a tagged-photon beam in Hall B at Jefferson Lab.

Structure and singly occupied molecular orbital analysis of anionic tautomers of guanine [PDF]

, 2008
Recently we reported the discovery of adiabatically bound anions of guanine which might be involved in the processes of DNA damage by low-energy electrons and in charge transfer through DNA.

Active employees in the future workplace: From job crafting to selfergetic job crafting

European Management Review, EarlyView.
Abstract The job crafting theory implies, but does not explicitly present the relationship between the self and the job. To fill the gap, we theorize upon the holistic view of the self, and selfergy, a new concept reflecting the unique manner by which employees craft their jobs. Based on the principles of the self‐determination theory, we have advanced

A possible signature of terrestrial planet formation in the chemical composition of solar analogs

, 2010
Recent studies have shown that the elemental abundances in the Sun are anomalous when compared to most (about 85%) nearby solar twin stars. Compared to its twins, the Sun exhibits a deficiency of refractory elements (those with condensation temperatures ...

Motivation for learning Chinese compared to European languages: An exploration in English secondary schools

Foreign Language Annals, EarlyView.
Abstract There is little published research on school‐aged learners of Mandarin Chinese in anglophone contexts. This article explores English secondary school pupils' motivation for learning Chinese compared to European languages. The research questions were: (1) What is the strength and nature of pupils' self‐reported motivation for learning languages?

Dirac Neutrino Dark Matter

, 2007
We investigate the possibility that dark matter is made of heavy Dirac neutrinos with mass in the range [O(1) GeV- a few TeV] and with suppressed but non-zero coupling to the Standard Model Z as well as a coupling to an additional Z' gauge boson.
