We address a well known problem of nonlinear image diffusion techniques, namely the loss of texture information. We do so by first determining that it is due to unaccounted correlation structure in the image which we subsequently mitigate by proposing a wavelet frame-based technique. This, by the same token establishes a theoretical bridge between the scale space methodology and the multiscale ...

Abstract From 2014 onwards Poland witnessed an unprecedented inflow of immigrant workers from Ukraine. Coupled with strong labour demand, this surge in supply provided a major contribution to Poland’s economic growth. However, due problems capturing immigration Labour Force Survey data has remained hitherto largely unaccounted official data. This paper uses range alternative sources estimate th...

Forestry is a natural climate solution for removing atmospheric carbon dioxide (CO2) and reaching net zero emissions. Managed boreal forests typically have extensive drainage ditch networks, these can be hotspots of anthropogenic greenhouse gas (GHG) emissions, potentially offsetting the terrestrial gain. However, there lack data detailing GHG emissions from ditches on mineral soils, where most...

Inconsistencies in Interpreting the Atmospheric Neutrino Anomaly John M. LoSecco Physics Department, University of Notre Dame, Notre Dame, Indiana 46556, USA Abstract. We note a discrepancy between the value of R expected on the basis of the muon neutrino angular distribution and the value actually observed. The energy independence of R leads to a fine tuning problem. This may be indicative of ...

The etymology of Modern Greek ovci ‘no!’ has never really been in doubt, as the Ancient Greek emphatic negative oujciv ‘not’ is surely its source. However, various details of its development from oujciv remain unaccounted for, in particular the vowel in the initial syllable, the placement of the accent, and the functional shift from ‘not’ to ‘no!’. An explanation that seeks an answer for these ...

Presently unaccounted but quite probable ”chemical factor” may be responsible for the formation of old metal-rich globular clusters (MRGCs) in spheroids, as well as of their conterparts, young (intermediate–age) massive star clusters (MSCs) in irregulars. Their formation presumably occurs ∼ at the same stage of the host galaxies’ chemical evolution and is related to the essentially increased SF...

In order to investigate the origin of the until now unaccounted excess noise and to minimize the uncontrollable phenomena at the transition in X-ray mi-crocalorimeters we have developed superconducting transition-edge sensors into an edgeless geometry, the so-called Corbino disk (CorTES), with super-conducting contacts in the centre and at the outer perimeter. The measured rms current noise and...

The effect of a uniform measurement bias, due to background light, stray light, detector dark current, or detector offset, on phase retrieval wavefront sensing algorithms is analyzed. Simulation results indicate that the root-mean-square error of the retrieved phase can be more sensitive to an unaccounted-for signal bias than to random noise in practical scenarios. Three methods for reducing th...
