• Excitability in a quantum dot semiconductor laser with optical injection 

  Goulding, David; Hegarty, Stephen P.; Rasskazov, Oleg; Melnik, Sergey; Hartnett, Mark; Greene, G.; McInerney, John G.; Rachinskii, Dmitrii; Huyet, Guillaume (American Physical Society, 2007)

  We experimentally analyze the dynamics of a quantum dot semiconductor laser operating under optical injection. We observe the appearance of single- and double-pulse excitability at one boundary of the locking region. ...
• Emerging meso- and macroscales from synchronization of adaptive networks 

  Gutierrez, R.; Amann, Andreas; Assenza, S.; Gomez-Gardenes, J.; Latora, V.; Boccaletti, S. (American Physical Society, 2011)

  We consider a set of interacting phase oscillators, with a coupling between synchronized nodes adaptively reinforced, and the constraint of a limited resource for a node to establish connections with the other units of the ...
• Analytical limitation for time-delayed feedback control in autonomous systems 

  Hooton, Edward W.; Amann, Andreas (American Physical Society, 2012)

  We prove an analytical limitation on the use of time-delayed feedback control for the stabilization of periodic orbits in autonomous systems. This limitation depends on the number of real Floquet multipliers larger than ...
• Classification of polyhedral shapes from individual anisotropically resolved cryo-electron tomography reconstructions 

  Bag, Sukantadev; Prentice, Michael B.; Liang, Mingzhi; Warren, Martin J.; Roy Choudhury, Kingshuk (BioMed Central, 2016-06-13)

  Background: Cryo-electron tomography (cryo-ET) enables 3D imaging of macromolecular structures. Reconstructed cryo-ET images have a “missing wedge” of data loss due to limitations in rotation of the mounting stage. Most ...
• Random walks on finite quantum groups 

  McCarthy, J.P. (University College Cork, 2017)

  Of central interest in the study of random walks on finite groups are ergodic random walks. Ergodic random walks converge to random in the sense that as the number of transitions grows to infinity, the state-distribution ...
