Spectra for the product of Gaussian noises

Products of Gaussian noises often emerge as the result of non-linear detection techniques or as a parasitic effect, and their proper handling is important in many practical applications, including in fluctuation-enhanced sensing, indoor air or environmental quality monitoring, etc. We use Rice's random phase oscillator formalism to calculate the power density spectra variance for the product of two Gaussian band-limited white noises with zero-mean and the same bandwidth W. The ensuing noise spectrum is found to decrease linearly from zero frequency to 2W, and it is zero for frequencies greater than 2W. Analogous calculations performed for the square of a single Gaussian noise confirm earlier results. The spectrum at non-zero frequencies, and the variance of the square of a noise, is amplified by a factor two as a consequence of correlation effects between frequency products. Our analytic results is corroborated by computer simulations.Comment: submitted for publicatio

Modern technologies production of cheese enriched with Omega - 3 fatty acids

Thermochromic films of MgxV1-xO2 were made by reactive dc magnetron   sputtering onto heated glass. The metal-insulator transition   temperature decreased by similar to 3 K/at. %Mg, while the optical   transmittance increased concomitantly. Specifically, the transmittance   of visible light and of solar radiation was enhanced by similar to 10%   when the Mg content was similar to 7 at. %. Our results point at the   usefulness of these films for energy efficient fenestration

Depression and mentalizing: a psychodynamic therapy process study

The present study aimed to explore the relationship between changes in depressive symptoms and the capacity to mentalize over the course of a 3-month inpatient psychodynamic therapy in a sample of 56 patients with depression. Depressive symptoms and mentalizing were assessed weekly during treatment and at 1-year follow-up with the Beck Depression Inventory and the Reflective Functioning Questionnaire. Data were analyzed using latent growth curve modeling with structured residuals. In the total sample, depressive symptoms improved on average from baseline to the end of treatment, while mentalizing skills did not. However, individual variations were observed in mentalizing skills, with some patients improving while others did not. Within-patient residual changes in mentalizing skills did not predict residual changes in depressive symptoms. Accordingly, the results did not support mentalizing as a mechanism of change at this level. Nonetheless, between-patient effects were found, showing that patients with higher levels of mentalizing at baseline and patients whose mentalizing skills improved over the course of therapy also had greater reductions in depressive symptoms. We suggest that the presence of relatively higher mentalizing skills might be a factor contributing to moderately depressed individuals’ ability to benefit from treatment, while relatively poor or absent mentalizing capacity might be part of the dynamics underlying treatment resistance in individuals with severe depression

Electron effective mass in Sn-doped monoclinic single crystal β\beta-gallium oxide determined by mid-infrared optical Hall effect

The isotropic average conduction band minimum electron effective mass in Sn-doped monoclinic single crystal $\beta$-Ga$_2$O$_3$ is experimentally determined by mid-infrared optical Hall effect to be $(0.284\pm0.013)m_{0}$ combining investigations on ($010$) and ($\bar{2}01$) surface cuts. This result falls within the broad range of values predicted by theoretical calculations for undoped $\beta$-Ga$_2$O$_3$. The result is also comparable to recent density functional calculations using the Gaussian-attenuation-Perdue-Burke-Ernzerhof hybrid density functional, which predict an average effective mass of $0.267m_{0}$ (arXiv:1704.06711 [cond-mat.mtrl-sci]). Within our uncertainty limits we detect no anisotropy for the electron effective mass, which is consistent with most previous theoretical calculations. We discuss upper limits for possible anisotropy of the electron effective mass parameter from our experimental uncertainty limits, and we compare our findings with recent theoretical results

Multiple Dimensions of Strategic Spatial Planning: Local Authorities Navigating between Rationalities in Competitive and Collaborative Settings

This article scrutinises the role of strategic and communicative rationalities in strategic spatial planning. It contributes to the theoretical discussion on strategic spatial planning, where communicative rationality has usually been taken as a normative standpoint, despite the evident role of strategic rationality in guiding planning on the ground. To develop means for equally recognising the two rationalities, the article introduces an analytical framework in which four strategic orientations are identified by juxtaposing coordination through communicative and strategic rationalities with competitive and collaborative settings of social interaction. Its applicability is illustrated with the example of strategic spatial planning in Turku (Finland)

Coalescence of nanoscale metal clusters: Molecular-dynamics study

We study the coalescence of nanoscale metal clusters in an inert-gas atmosphere using constant-energy molecular dynamics. The coalescence proceeds via atomic diffusion with the release of surface energy raising the temperature. If the temperature exceeds the melting point of the coalesced cluster, a molten droplet forms. If the temperature falls between the melting point of the larger cluster and those of the smaller clusters, a metastable molten droplet forms and freezes.Comment: 5 figure

Growth of Epitaxial Tungsten Nanorods

A simple vapour deposition technique was used to prepare WO3 one-dimensional nanostructures.WO3 is sublimated at a relatively low temperature (550 1C) in air at atmospheric pressure.The sublimated species are condensed on mica substrate at 500 1C.Single crystalline nanorods are grown in epitaxy on the mica surface with a growth axis along [0 1 0] directions and (0 0 1) plane parallel to the substrate.A growth process is proposed in which the formation of a onedimensional tetragonal tungsten bronze as precursor is the determining factor
