Controlling the phase of a light beam with a single molecule
, 2011 We employ heterodyne interferometry to investigate the effect of a single organic molecule on the phase of a propagating laser beam. We report on the first phase-contrast images of individual molecules and demonstrate a single-molecule electro-optical ...

Coexistence of Josephson oscillations and novel self-trapping regime in optical waveguide arrays [PDF]
, 2006 Considering the coherent nonlinear dynamics between two weakly linked optical waveguide arrays, we find the first example of coexistence of Josephson oscillations with a novel self-trapping regime.

Nonlinear optical switching matrix
Optics Letters, 2003 We show that nonlinear directional couplers with variable coupling coefficients can be used to compose a special kind of switching matrix. The switching matrix can be controlled by the signal itself or by a strong pump. Light routing is realized by adjustment of the power of the signal or the pump.

FEBS Open Bio, EarlyView.Light activation of the photoswitchable cannabinoid ligand azo‐HU308 triggers Ca2+ influx in pancreatic β‐cells through TRPC channels, independent of CB2 cannabinoid receptors. This reveals a non‐GPCR pathway for cannabinoid modulation of β‐cell Ca2+ dynamics and establishes azo‐HU308 as an optical tool to study cannabinoid signaling through TRP ...

Simulation of 1 x 2 OTDM router employing symmetric Mach-Zehnder switches [PDF]
, 2005 In high-speed all-optical time division multiplexed (OTDM) routers it is desirable to carry out data routing, switching, clock recovery and synchronisation in the optical domain in order to avoid the bottleneck due to optoelectronics conversion.

Pathogenic Neurofibromatosis type 1 gene variants in tumors of non‐NF1 patients and role of R1276
FEBS Open Bio, EarlyView.Somatic variants of the neurofibromatosis type 1 (NF1) gene occur across neoplasms without clinical manifestation of the disease NF1. We identified emerging somatic pathogenic NF1 variants and hotspots, for example, at the arginine finger 1276. Those missense variants provide fundamental information about neurofibromin's role in cancer.

Conformational spread as a mechanism for cooperativity in the bacterial flagellar switch [PDF]
, 2010 The bacterial flagellar switch that controls the direction of flagellar rotation during chemotaxis has a highly cooperative response. This has previously been understood in terms of the classic two-state, concerted model of allosteric regulation.
