INVERSE CORRECTION OF FOURIER TRANSFORMS FOR ONE-DIMENSIONAL STRONGLY SCATTERING APERIODIC LATTICES
Journal of Fundamental and Applied Sciences, 2016 The accuracy of the Fourier transform (FT), advantageous for the aperiodic lattice (AL) design, is significantly improved for strongly scattering periodic lattices (PLs) and ALs.

Common misconceptions in crystallography and crystal optics
Journal of Applied Crystallography, EarlyView.Six recurrent misconceptions in crystallography, some involving mineral and crystal optics, are analyzed and discussed. The explanation of these and similar misconceptions could serve as educational resources for teachers.Did you know that an X‐ray diffraction pattern is not a spectrum?

Doklady Belorusskogo gosudarstvennogo universiteta informatiki i radioèlektroniki, 2019 An automatic control system for the 1st order aperiodic object is suggested. The structural scheme includes main control circuit with a PID-regulator in it and a disturbance compensation circuit realized by two additional PID-regulators.

Exploring oxide quasicrystals in internal space
Acta Crystallographica Section A, EarlyView.The internal space expansion with variable system size is investigated for three different oxide quasicrystal systems. Patches of 7800, 4800 and 3600 vertices are examined in Ba–Ti–O/Pt(111), Eu–Ti–O/Pd(111) and Sr–Ti–O/Pd(111), respectively. This internal space inspection provides unique structural information for quasicrystalline systems, which goes ...

Strategic Influencers and the Shaping of Beliefs
The RAND Journal of Economics, EarlyView.ABSTRACT Influencers, from propagandists to sellers, expend vast resources targeting agents who amplify their message through word‐of‐mouth communication. While agents differ in network position, they also differ in their bias: Agents may naturally read articles with a particular slant or buy products from a certain seller.

Fixed-Parameter Extrapolation and Aperiodic Order
, 2012 Fix any $ \in\mathbb{C}$. We say that a set $S\subseteq\mathbb{C}$ is $ $-$convex$ if, whenever $a$ and $b$ are in $S$, the point $(1- )a+ b$ is also in $S$. If $S$ is also (topologically) closed, then we say that $S$ is $ $-$clonvex$. We investigate the properties of $ $-convex and $ $-clonvex sets and prove a number of facts about them ...

Addiction, EarlyView.Abstract Aims To identify the brain activity profiles associated with alcohol consumption and to address its causes. Furthermore, we sought to examine the relationship between these electrophysiological markers and the excitation–inhibition balance, as well as to explore the potential moderating role of sex in these associations.

eLifeNon-human animal models have indicated that the ratio of excitation to inhibition (E/I) in neural circuits is experience dependent, and changes across development. Here, we assessed 3T Magnetic Resonance Spectroscopy (MRS) and electroencephalography (EEG)

The First Archaeomagnetic Age at Tiwanaku and Implications for Dating Andean Metallurgical Furnaces
Archaeometry, EarlyView.ABSTRACT This paper presents the first archaeomagnetic dating at Tiwanaku (Andean Altiplano). We compared the geomagnetic field values recorded by a metallurgical furnace against an updated SHAWQ2k‐SH global model and a regional intensity curve, both of which include, for the first time, high‐quality intensity data from the Southern Hemisphere.
