Polarization Beam Splitter Based on Si₃N₄/SiO₂ Horizontal Slot Waveguides for On-Chip High-Power Applications

Sensors, 2020
In this paper, we propose an Si3N4/SiO2 horizontal-slot-waveguide-based polarization beam splitter (PBS) with low nonlinearity for on-chip high-power systems.

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

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.

Design and Analysis of Punctured Terminated Spatially Coupled Protograph LDPC Codes With Small Coupling Lengths

IEEE Access, 2018
Spatially coupled protograph (SC-P) low-density parity-check codes can achieve excellent performance and simple implementation when the coupling length is sufficiently large. However, in the case of small coupling lengths, terminated SC-P (TE-SC-P) codes

Multiscaling of the graph length in Coupled Map Lattices

Journal of Physics A: Mathematical and General, 1997
Summary: We consider generalized scaling exponents for the graph of a scalar function to allow for multiscaling of the graph length. These generalized exponents are related to the moments of the distribution of roughness over the support of the graph. We report numerical computations of these exponents for the graphs of Coupled Map Lattices exhibiting ...

Tilt-to-length coupling in LISA Pathfinder : Analytical modeling

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-

Internal Flow Field and Loss Analysis of a Magnetic Drive Pump’s Cooling Circuit

Energies, 2023
The cooling circuit is an important component of the magnetic drive pump because it prevents demagnetization of the permanent magnet and damage to the containment shell owing to a high temperature increase. In this paper, the flow field and losses of the

Sexual intimacy in couples is associated with longer telomere length [PDF]

Psychoneuroendocrinology, 2017
High-quality relationships have been shown to be beneficial for physical and mental health. This study examined overall relationship satisfaction and perceived stress as well as daily reports of partner support, partner conflict, and physical intimacy obtained over the course of one week in a sample of 129 high and low stress mothers.
