Amplitude modulation of femtosecond laser pulses in the megahertz range for frequency-multiplexed two-photon imaging.

Optics express

Tsyboulski D, Orlova N, Saggau P.
PMID: 28437905
Opt Express. 2017 Apr 17;25(8):9435-9442. doi: 10.1364/OE.25.009435.

We present a frequency-multiplexed multi-site two-photon imaging method utilizing amplitude modulation of femtosecond laser pulses in the MHz range to tag each excitation beam and the corresponding fluorescence signals with specific frequencies. The frequency tags are generated with an...

Different ways of looking at the force between two nanocrystals.

The Journal of chemical physics

Lange A, Danecker F, Bauer G, Gribova N, Gross J.
PMID: 26723659
J Chem Phys. 2015 Dec 28;143(24):244115. doi: 10.1063/1.4937395.

The potential of mean force (PMF) between two nanocrystals (NCs) represents an effective interaction potential that is essential when explaining the assembly of NCs to superstructures. For a given temperature, the PMF is obtained best from molecular dynamics simulations....

Magnetic field energy dissipation due to particle trapping in a force-free configuration of collisionless pair plasmas.

Physical review. E, Statistical, nonlinear, and soft matter physics

Sakai JI, Sugiyama D, Haruki T, Bobrova N, Bulanov S.
PMID: 11308957
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Apr;63(4):046408. doi: 10.1103/PhysRevE.63.046408. Epub 2001 Mar 27.

It is shown by using a two-dimensional, fully relativistic, electromagnetic particle-in-cell simulation code that a force-free magnetic configuration in collisionless, electron-positron (pair) plasmas becomes unstable against current-driven Buneman instability and subsequently there occurs a strong magnetic field energy dissipation...

Eur Heart J. 2021 Dec 28;43(1):18-28. doi: 10.1093/eurheartj/ehab504.

AIMS: Data suggest that women have worse outcomes than men after coronary artery bypass grafting (CABG), but results have been inconsistent across studies. Due to the large differences in baseline characteristics between sexes, suboptimal risk adjustment due to low-quality...

Removing independent noise in systems neuroscience data using DeepInterpolation.

Nature methods

Lecoq J, Oliver M, Siegle JH, Orlova N, Ledochowitsch P, Koch C.

Progress in many scientific disciplines is hindered by the presence of independent noise. Technologies for measuring neural activity (calcium imaging, extracellular electrophysiology and functional magnetic resonance imaging (fMRI)) operate in domains in which independent noise (shot noise and/or thermal...

Damage to specific brain circuits can cause specific neuropsychiatric symptoms. Therapeutic stimulation to these same circuits may modulate these symptoms. To determine whether these circuits converge, we studied depression severity after brain lesions (n = 461, five datasets), transcranial...
