Coupling length: a generalized gleno-acetabular distance measurement for interpreting the size and gait of quadrupedal trackmakers

open access: yesSwiss Journal of Geosciences, 2022
The gleno-acetabular distance D GA , a conventional proxy for the size of a quadrupedal trackmaker, is often estimated as the distance GA between the midpoint between a left and right pair of pes tracks and the midpoint between a selected pair of left ...

Two-wavelength WDM multiplexers based on combined fiber structures

open access: yesРоссийский технологический журнал, 2021
One of the main directions in the development of optical communication systems is associated with the use of optical fiber (ОF) for data reception and transmission.

Calculation of the Coupling Coefficient in Step-Index Multimode Polymer Optical Fibers Based on the Far-Field Measurements

open access: yesFrontiers in Physics, 2022
Using the power flow equation (PFE), this article investigates mode coupling in step-index (SI) multimode (MM) polymer optical fiber (POF). This equation’s coupling coefficient was initially fine-tuned so that it could appropriately reconstruct ...

Mode Coupling Analysis for a Mode Selective Coupler Using the Supermode Theory

open access: yesPhotonics, 2022
In this paper, the mode selective coupler (MSC) is analyzed using the supermode theory. It is shown that all characteristic parameters of the MSC can be obtained using the propagation constants of the supermodes supported by the MSC structure. Simulation

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

open access: yesMicromachines, 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.

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

open access: yesFrontiers 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.

Variable length path coupling [PDF]

open access: yesRandom 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.

Coupled length scales in eroding landscapes [PDF]

open access: yesPhysical Review E, 2001
We report results from an empirical study of the anisotropic structure of eroding landscapes. By constructing a novel correlation function, we show quantitatively that small-scale channel-like features of landscapes are coupled to the large-scale structure of drainage basins. We show additionally that this two-scale interaction is scale-dependent.

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'

Interleaver Design for Small-Coupling-Length Spatially Coupled Protograph LDPC-Coded BICM Systems Over Wireless Fading Channels

open access: yesIEEE Access, 2020
As a class of convolutional error-correction codes (ECCs), spatially coupled protograph low-density parity-check (SC-PLDPC) codes with a sufficiently large coupling length can approach the channel capacity under belief propagation (BP) decoding. However,
