Coherent interactions of dissipative spatial solitons.

Optics letters

Ultanir EA, Stegeman GI, Lange CH, Lederer F.
PMID: 14759052
Opt Lett. 2004 Feb 01;29(3):283-5. doi: 10.1364/ol.29.000283.

We report observation of the interaction between two coherent dissipative spatial solitons in a periodically patterned semiconductor optical amplifier with power levels of tens of milliwatts. The interactions are nonlocal and phase dependent and exhibit surprising features, such as...

Cyclin G-associated kinase (GAK) is a ubiquitous serine/threonine kinase that facilitates clathrin uncoating during vesicle trafficking. GAK phosphorylates a coat adaptor component, AP2M1, to help achieve this function. GAK is also implicated in Parkinson's disease through genome-wide association studies....

Dissipative photonic lattice solitons.

Optics letters

Ultanir EA, Stegeman GI, Christodoulides DN.
PMID: 15119397
Opt Lett. 2004 Apr 15;29(8):845-7. doi: 10.1364/ol.29.000845.

We show that discrete dissipative optical lattice solitons are possible in waveguide array configurations that involve periodically patterned semiconductor optical amplifiers and saturable absorbers. The characteristics of these low-power soliton states are investigated, and their propagation constant eigenvalues are...

Assessment of prevalence of hypovitaminosis D in multiethnic population of the United Arab Emirates.

Journal of advanced pharmaceutical technology & research

Sridhar SB, Rao PG, Multani SK, Jain M.
PMID: 27144152
J Adv Pharm Technol Res. 2016 Apr-Jun;7(2):48-53. doi: 10.4103/2231-4040.177202.

United Arab Emirates (UAE) has a high prevalence of hypovitaminosis D. Not much data are available regarding the prevalence of Vitamin D deficiency among multiethnic UAE adult population. (1) To determine the prevalence of hypovitaminosis D in multiethnic UAE...

Stability properties of multiwavelength, incoherent, dissipative spatial solitons.

Optics letters

Ultanir EA, Stegeman GI, Lange CH.
PMID: 15789726
Opt Lett. 2005 Mar 01;30(5):531-3. doi: 10.1364/ol.30.000531.

We have investigated the interaction between two dissipative spatial solitons of different frequencies in periodically patterned semiconductor optical amplifiers. The experimental results are in good agreement with the theory. Simulations suggest that multiwavelength interactions do not produce stable bound...

Stable dissipative solitons in semiconductor optical amplifiers.

Physical review letters

Ultanir EA, Stegeman GI, Michaelis D, Lange CH, Lederer F.
PMID: 12857133
Phys Rev Lett. 2003 Jun 27;90(25):253903. doi: 10.1103/PhysRevLett.90.253903. Epub 2003 Jun 27.

We have observed for the first time stable spatial solitons in semiconductor optical amplifiers. Soliton destabilization due to the growth of background noise was suppressed by using patterned electrodes on the device. Numerical simulations fit very well with the...

Stable spatial solitons in semiconductor optical amplifiers.

PMID: 12653362
Opt Lett. 2003 Feb 15;28(4):251-3. doi: 10.1364/ol.28.000251.

The existence of stable dissipative spatial solitons at low intensities in patterned electrode semiconductor optical amplifiers (SOAs) is predicted theoretically. In contrast to conventional SOAs, this system may support stable solitons because the inherent saturating losses provide subcritical bifurcations...

Synaptic vesicle (SV) release probability (Pr), determines the steady state and plastic control of neurotransmitter release. However, how diversity in SV composition arises and regulates the Pr of individual SVs is not understood. We found that modulation of the...
