DNA-controlled excitonic switches.

Abstract: Fluorescence resonance energy transfer (FRET) is a promising means of enabling information processing in nanoscale devices, but dynamic control over exciton pathways is required. Here, we demonstrate the operation of two complementary switches consisting of diffusive FRET transmission lines in which exciton flow is controlled by DNA. Repeatable switching is accomplished by the removal or addition of fluorophores through toehold-mediated strand invasion. In principle, these switches can be networked to implement any Boolean function.

The Development of Creative Capabilities in and out of Creative Organizations: Three Case Studies

Abstract: This paper describes and analyses how creative organizations develop and use routines and processes to strengthen their creative capabilities. Using an exploratory framework based in resource-based theory and creativity literature, it focuses on the role of the creative entrepreneur as a key component for organizations developing creative capabilities. The creative entrepreneur or agent builds collaboration, exploits knowledge and enhances relationships in and out of an organization. Drawing on three in-depth case studies from different sectors (theatre, sports and software), the article expands the idea of creative capabilities to encompass routines and processes in organizations in industries generally not considered ‘creative’. Furthermore, it outlines how the creative entrepreneur is instrumental in developing and using the creative routines so that they form creative capabilities. Based on the analysis, the article discusses creative capabilities, collaboration in the process, and the creative entrepreneur’s role in developing and using them.

Constraining the High-energy Emission from Gamma-Ray Bursts with Fermi

Abstract: We examine 288 gamma-ray bursts (GRBs) detected by the Fermi Gamma-ray Space Telescope's Gamma-ray Burst Monitor (GBM) that fell within the field of view of Fermi's Large Area Telescope (LAT) during the first 2.5 years of observations, which showed no evidence for emission above 100 MeV. We report the photon flux upper limits in the 0.1-10 GeV range during the prompt emission phase as well as for fixed 30 s and 100 s integrations starting from the trigger time for each burst. We compare these limits with the fluxes that would be expected from extrapolations of spectral fits presented in the first GBM spectral catalog and infer that roughly half of the GBM-detected bursts either require spectral breaks between the GBM and LAT energy bands or have intrinsically steeper spectra above the peak of the νF ν spectra (E pk). In order to distinguish between these two scenarios, we perform joint GBM and LAT spectral fits to the 30 brightest GBM-detected bursts and find that a majority of these bursts are indeed softer above E pk than would be inferred from fitting the GBM data alone. Approximately 20% of this spectroscopic subsample show statistically significant evidence for a cutoff in their high-energy spectra, which if assumed to be due to γγ attenuation, places limits on the maximum Lorentz factor associated with the relativistic outflow producing this emission. All of these latter bursts have maximum Lorentz factor estimates that are well below the minimum Lorentz factors calculated for LAT-detected GRBs, revealing a wide distribution in the bulk Lorentz factor of GRB outflows and indicating that LAT-detected bursts may represent the high end of this distribution.
