Tilt-to-length coupling in LISA Pathfinder: A data analysis [PDF]

Physical Review D, 2023
We present a study of the tilt-to-length coupling noise during the LISA Pathfinder mission and how it depended on the system’s alignment. Tilt-to-length coupling noise is the unwanted coupling of angular and lateral spacecraft or test mass motion into the primary interferometric displacement readout.

Tilt-to-length coupling in LISA Pathfinder : Analytical modeling [PDF]

Physical Review D, 2023
Tilt-to-length coupling was the limiting noise source in LISA Pathfinder between 20 and 200 mHz before subtraction in post-processing. To prevent the adding of sensing noise to the data by the subtraction process, the success of this strategy depended on a previous direct noise reduction by test mass alignment. The exact dependency of the level of tilt-

The molecular basis of coupling between poly(A)-tail length and translational efficiency [PDF]

eLife, 2021
In animal oocytes and early embryos, mRNA poly(A)-tail length strongly influences translational efficiency (TE), but later in development this coupling between tail length and TE disappears.

Tilt-to-length coupling in LISA Pathfinder: Long-term stability [PDF]

Physical Review D
The tilt-to-length coupling during the LISA Pathfinder mission has been numerically and analytically modeled for particular time spans. In this work, we investigate the long-term stability of the coupling coefficients of this noise. We show that they drifted slowly (by 1  μm/rad and 6×10−6 in 100 days) and were strongly correlated to temperature ...

Tilt-to-length coupling in LISA—uncertainty and biases [PDF]

Classical and Quantum Gravity
Abstract The coupling of the angular jitter of the spacecraft and their sub-assemblies with the optical bench and the telescope into the interferometric length readout will be a major noise source in the LISA mission. We refer to this noise as tilt-to-length (TTL) coupling.

Coupling Length Phase Matching in Parallel Waveguides [PDF]

Frontiers in Optics 2015, 2015
We show that phase-matching for frequency conversion is possible in a system consisting of two parallel waveguides without any spatial modulation of linear or nonlinear optical properties, both for second and for third-order ...

Length of the coupling sequence of Tn916 [PDF]

Journal of Bacteriology, 1994
The coupling sequences of conjugative transposons are short variable sequences derived from the DNA flanking the transposon insertion site. We show here that for Tn916 the left coupling sequence is 6 bases long. The right-hand end of the transposon can excise with either four or five T's, but integration occurs to restore the five T's at the transposon'

An Optical Measuring Transducer for a Micro-Opto-Electro-Mechanical Micro-g Accelerometer Based on the Optical Tunneling Effect

Micromachines, 2023
Micro-opto-electro-mechanical (MOEM) accelerometers that can measure small accelerations are attracting growing attention thanks to their considerable advantages—such as high sensitivity and immunity to electromagnetic noise—over their rivals.

Variable length path coupling [PDF]

Random Structures & Algorithms, 2007
AbstractWe present a new technique for constructing and analyzing couplings to bound the convergence rate of finite Markov chains. Our main theorem is a generalization of the path coupling theorem of Bubley and Dyer, allowing the defining partial couplings to have length determined by a random stopping time.

Influence of launch beam distribution on power flow and angular division multiplexing in seven-core silica optical fibers

Frontiers in Physics, 2022
We analyze the effect of launch beam distribution on space-division multiplexing (SDM) performance in multimode multicore silica optical fibers (MM MC SOF) with seven cores.
