الوصف: An electrodynamic problem of laser radiation scattering in an integrated-optical waveguide containing small statistical irregularities (interface roughness and irregularities of the refractive indices of the waveguide-forming media) is considered. The possibility of using the waveguide scattering of laser radiation for extracting the information on the statistical properties of irregularities from noisy data of the scattering diagram in a far-field zone is shown. An algorithm for reconstructing the autocorrelation function of irregularities for the correlation interval changing within a wide range is described. The possibility of restoring a given Gaussian autocorrelation function that describes statistical irregularities of the waveguide substrate surface for a correlation interval changing between 10 nm and 10 μm and a high-level additive white real noise is shown by computer simulation.

(B) A histogram of these vote shifts shows that these outliers typically favour Erdoğan in the sense that large shifts from anti to pro Erdoğan are much more common than the other way around. (C) Looking at the proportion of ballot boxes coming from districts with two or fewer ballot boxes as a function of vote shifts, we see that these extreme vote shifts favouring Erdoğan occur predominantly in districts with fewer ballot boxes.

These displacements are much smaller displacements in the Russian or Venezuelan elections (dashed lines); the reference elections are shown as dotted lines. (B) Units in the 2023 and 2018 Turkish elections are ranked according to their electorate size. We show the cumulative vote share, cum i ( v ), calculated over all units with a size greater than the given rank. As in 2018, we observe a characteristic “hockey stick” in 2023, meaning that units with high rank (low electorate size) show a clear tendency to favour Erdoğan.

In 2018, a majority of more than 50% is achieved by including boxes with a turnout of more than 90% (blue). In the first round in 2023 (red line) we observe similar characteristics with higher turnout and lower vote shares (below 50%), whereas in the second round (yellow) Erdoğan reached a majority of votes.

The table gives the 38 districts in which ballot boxes with such extreme vote shifts occurred significantly more often than expected (after Bonferroni adjustment for mutliple testing).

For both elections, we find a visible correlation in the region of high vote and turnout (e.g. more than 80%), which can be associated with ballot stuffing. A box plot (red horizontal boxes) shows the 25th, 50th and 75th percentiles of voter turnout as a function of votes (whiskers indicate the 95% confidence interval). (C) To adjust for regional characteristics, the fingerprints can be adjusted by rescaling the vote and turnout shares by their typical levels in the unit’s region, resulting in the standardised fingerprint shown. (D) Traces of voter coercion can be identified by comparing the standardised fingerprints of small (red lines) and large (blue) units, as voter coercion results in their being shifted towards inflated votes and turnout, as observed here. (E,F) The standardised fingerprints of the second round are similar to those of the first round.

Considering only areas with an electorate size of less than 100 (C, D), or alternatively ballot boxes from areas with one or two ballot boxes (E, F), results in a bimodal distribution with a large mode in the region with very high turnout and votes for Erdoğan.

مصطلحات موضوعية: additive noise, and regularisation method, Inverse light scattering problem, waveguide statistical irregularities
الوصف: An approximate correct solution of the inverse problem of light scattering in a planar waveguide with small statistical irregularities is obtained. The latter is reduced to the determination of the autocorrelation function of irregularities on the far zone scattering data. The solution in this case is found with the help of Tikhonov's regularisation method. © 2001 IOS Press.
