Length of the coupling sequence of Tn916 [PDF]

open access: yesJournal 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'

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

open access: yeseLife, 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.

Investigation of mode coupling in strained and unstrained multimode step-index POFs using the Langevin equation

open access: yesHeliyon, 2023
The Langevin equation (LE) is used to evaluate mode coupling in multimode step-index polymer optical fiber (SI POF) that is both unstrained and strained.

Anomalous Optical Propagation and Potential Sensitivity Enhancement in a Micro-Coil Resonator Based on Microfiber

open access: yesIEEE Photonics Journal, 2021
The resonance characteristics of the micro-coil resonator(MCR) with different turns and coupling conditions are presented, which show that the effective length of the MCR with small coupling coefficient at primary resonant is independent of the turns ...

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

open access: yesIEEE 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

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

open access: yesSensors, 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.

Coupling Length Phase Matching in Parallel Waveguides [PDF]

open access: yesFrontiers 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 ...

Universality in Phase Transitions for Ultracold Fermionic Atoms [PDF]

open access: yes, 2005
We describe the gas of ultracold fermionic atoms by a functional integral for atom and molecule fields. The crossover from Bose-Einstein condensation (BEC) to BCS-type superfluidity shows universal features in terms of a concentration parameter for the ...

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

open access: yesPhysical 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-
