Abstract

Background
Accumulating evidence indicates that trimethylamine-N-oxide (TMAO) may play a causal role in cardiovascular disease (CVD), chronic kidney disease (CKD) and type 2 diabetes (T2D). TMAO plasma concentrations show considerable intra- and inter-individual variation, underscoring the need for a reference interval in the general population to identify elevated TMAO concentrations.

Methods
TMAO concentrations were determined using an LC-MS/MS assay in a community-based sample of the PopGen control cohort consisting of 694 participants (54% men; aged 25–82 years) free of clinical CVD, CKD and T2D. We defined reference intervals for TMAO concentrations in human plasma using the 2.5th and 97.5th percentiles. Using multivariable regression analysis we analyzed the association of estimated glomerular filtration rate (eGFR), sex, and dietary intake and TMAO plasma concentrations.

Results
TMAO plasma concentrations were positively skewed and differed by sex. The median TMAO plasma concentration in men was 3.91 (Q1–Q3: 2.87–6.10) μmol/L and the reference interval 1.28–19.67 μmol/L (2.5th–97.5th percentile). In women median TMAO plasma concentration was 3.56 (Q1–Q3: 2.41–5.15) μmol/L and the reference interval 1.08–17.12 μmol/L. In multivariable regression analysis plasma TMAO was associated with sex, renal function and diet. The association of TMAO and diet was significant for intake of fish and shellfish in men only.

Conclusions
In a community-based sample free of apparent CVD and renal disease, we report the distribution of TMAO plasma concentrations with sex, renal function and diet as factors associated with plasma TMAO, and suggest reference intervals. These data may facilitate standardized comparisons of TMAO across populations.

Published: February 2020

Abstract
In this paper, a graded-index metamaterial (GIM) nanostructured waveguide is proposed to enhance the performance of solar cells via a tunable absorption spectrum. The proposed four-layer nanostructured waveguide consists of two GIM and SiNx films which are squeezes between glass substrate and air. Using a transmission matrix method, the transmittances as well as the reflectance are calculated for different film thicknesses, refractive indices and incidence angles. We demonstrate that the reflectance is nearly zero where SiNx refractive index is 2.2 in vicinity of 620 nm. As the incident angle increases, the minimum reflectance wavelength blueshifts and slightly increase in the value. In addition, the variation in the minimum reflectance due to a change in the thickness of SiNx layer studied in detail. We show that the absorbance of a solar cell can be easily controlled by varying refractive index and/or thickness of SiNx layer in the proposed nanostructure. The result shows that the best efficiency occurs at normal incidence, n2 = 2.2, and d2 = 30 nm.
‘Imprison Cleon, Kill the Dead!’
Authors: Karatzoglou Orestis 
Published: February 2020

AbstractCleon was killed in the battle of Amphipolis in 422 BCE, but he is referred to as alive in the first parabasis of theClouds(591–594). This reference is customarily understood as simply a remnant of the first version of the play, which the author failed to integrate seamlessly into the surviving, revised version. Comparison with Pylaemenes, an Iliadic character of Paphlagonian origin, who is killed in Book 5 but reappears alive in Book 13, renders the reference to Cleon intelligible as an allusive joke.
Should Age Discrimination Be an Integral Part of Employment Discrimination Law?
Authors: Lurie Lilach 
Published: February 2020

Abstract
This Article argues that a universal approach to age discrimination promotes justice (including intergenerational justice) and efficiency. As explained herein, legal regimes regulate age discrimination in employment in various ways. While some regimes create specific anti–age discrimination legislation, others ban most kinds of employment discrimination, including age discrimination, in a general way. These latter promote a universal approach to age discrimination. The current Article explores the theoretical justifications for either a particularistic or a universal approach to age discrimination. Additionally, it enriches its theoretical discussion by taking and presenting a snapshot of current litigation in Israel – a country that has adopted a universal approach to age discrimination.
Age, Equality, and Vulnerability
Authors: Boni-Saenz Alexander A. 
Published: February 2020

Abstract
This Article uses age as an entry point for examining how temporal and methodological issues in egalitarianism make substantive equality an unattractive goal for vulnerability theory. Instead, vulnerability theory should adopt a continuous doctrine of sufficiency, which is a better fit with vulnerability theory’s underlying aims and rhetoric. Instead of evaluating what individuals have in relation to others, sufficiency refocuses the inquiry on whether we have enough throughout the lifecourse. In the context of vulnerability theory, enough should be defined as the capability to be resilient as guaranteed by the responsive state.
A Framework for Theoretical Inquiry into Law and Aging
Authors: Kohn Nina A. 
Published: February 2020

Abstract
With populations aging worldwide, the need for appropriate and just public policy related to old age is critical. Elder law scholars can support the creation of such policy by advancing the theoretical understanding of the relationship between law and aging — understanding that can help policymakers identify and prioritize goals, and evaluate potential interventions. This Article aims to provide a framework for this work by distilling the core theoretical questions at the intersection of law and aging. It also challenges common assumptions that could pose a barrier to developing a more robust theory of law and aging. Specifically, it argues that scholarship in this area will be most fruitful if it recognizes that the study and practice of “elder law” are intertwined but not a single unified field, that “preferential” treatment of older adults can be a form of discrimination, and that old age is not a universal human experience.
Electron-Impact Excitation of the 5p55d6s2 Autoionizing States in Ba Atom
Authors: Borovik V. , Hrytsko V. , Shafranyosh I. , Borovik O. 
Published: February 2020

The excitation cross-sections for the 5p55d6s2 autoionizing states of Ba atoms are studied experimentally and theoretically in an electron-impact energy range from the excitation thresholds of the states up to 600 eV. Experimental data are obtained by determining the intensities of lines in the ejected-electron spectra measured at an observation angle of 54.7∘. The incident-electron and ejected-electron energy resolutions are 0.2 eV and 0.07 eV, respectively. The calculations are performed in the distorted wave approximation by using relativistic radial wave functions obtained in the standard Dirac–Fock–Slater method. For all the states, the experimental cross-sections reach their maxima at low impact energies revealing by that predominantly the spin-exchange character of the excitation of autoionizing states. The structure of the near-threshold maxima indicates the formation of strong negative-ion resonances. At high impact energies, the shape and value of the cross-sections are determined by configuration and state mixing effects.

Published: February 2020

The capture, retention, and thermal desorption of deuterium and helium ions with medium energies implanted into tungsten-coated multilayer functional structures and the formation of corresponding radiation-induced damages in the crystal lattice of the tungsten coatings of those structures have been studied making use of the thermal desorption spectroscopy and electron microscopy methods. The behavior of deuterium and helium in the examined materials and its dependence on the post-implantation heating temperature, the dose of irradiation with D+ and He+ ions, and the irradiation condition – separate (making use of ions of only one kind) or sequential (making use of ions of both kinds) – are analyzed. A classification of radiation-induced defects and mechanisms of their annealing are proposed.

The work defines the area of use of unmanned aerial vehicles (UAVs) of the type of quadrocopter and calculated the acoustic field of propellers in order to reduce the level of noise at some distance. The main sources of noise, which are the hubs of the quadrocopter, are considered. The first samples of UAVs appeared in the middle of the last century as a separate type of promising weapons, but now quadrocopter,began to be actively used in the civilian sphere. The theory of the sound field of the aircraft's air propeller, which was proposed by L. Gutin to simulate the noise from each of the chochire screws of the quadrocopter, was carried out. A mathematical model has been created for calculating the total acoustic field all the of quadrocopter screws. The analysis and the defined area of use of UAVs of type quadrocopter and the calculation of acoustic field of screws is given in order to reduce the noise level at some distance. The authors conducted an analytical review of the existing models of UAVs and quadrocopters, considered general examples of use of quadrocopters, their purpose and scope of application. On the basis of analytical review of constructions the fundamental scheme of quadrocopter for researches is given. The article is driven by the principal scheme of the chosen quadrocopter with the description of its main nodes. Based on the results of calculations, the noise distribution schedules of different frequencies in the space are constructed. The results from sound pressure levels for each of the five harmonics. Description of direction of acoustic fields on separate frequencies each of harmonics is constructed using the Besselyu function. Mathematical calculations have been performed in MathCad 2015. There are two forces on each screw element: thrust and resistance of the rotary motion. From the Basic Law of mechanics it follows that this element, in its turn, influences the environment with equal magnitude and opposable directed forces.

Authors: Sidorov Ilya Andreevich , Manoilenko Alexander Alekseevich 
Published: February 2020

Currently, there is an increased interest in the creation of strapdown inertial navigation systems (SINS), which make up the information core of modern airborne systems for the orientation and navigation of spacecraft (SC). An urgent problem arises, which is associated with the development of high-precision algorithms for estimating and filtering data from the sensors of the SC motion parameters, the mathematical model of the SINS, calculating its errors and analyzing the effect of errors on the characteristics of the navigation system and orientation of the SC. A mathematical model is proposed for solving the problem of navigation and angular orientation of a small SC equipped with electromagnetic control elements, taking into account the filtering of “noisy” magnetometer data. The requirements are set for the accuracy of the angular orientation and stabilization of the SC in the mode of maintaining the triaxial orientation of the SC in the orbital coordinate system (OCS) and for the duration of the damping mode of the angular velocities obtained by the SC during separation from the launch vehicle (LV), and the mode of the initial construction of the triaxial orientation of the SC in OCS. The mathematical model includes: a model of the motion of the center of mass of the SC in the osculating elements of the orbit with specified parameters, a model of the angular motion of the SC around the center of mass, a model of the Earth’s magnetic field (EMF) and a model of filtering magnetometer data. As an arithm for filtering data from a magnetometer on the components of the magnetic induction vector of the EMF, a one-parameter algorithm of exponential smoothing (exponential moving average) is used, which belongs to the class of first-order filters with an infinite impulse response. The results of numerical simulation of the dynamic processes of navigation and the angular orientation of the SC after separation from the LV taking into account the filtering of magnetometer data by the method of exponential smoothing using mathematical models are presented, and the accuracy of the angular orientation and stabilization of the SC is estimated.
Mathematics Makes you Feel Attractive. Empowering New Alternative Masculinities in the Context of Mathematics Classrooms
Authors: Diez-Palomar Javier , Mara Liviu Catalin 
Published: February 2020

This article studies the relationship between masculinity construction in school and mathematics learning in boys. In this article, we introduce the variables of social interaction and the differentiation between the language of ethics and the language of desire to analyze the aspects related to mathematics learning in schoolboys. The methodology used is a literature review, paying particular attention to the techniques used in the literature and using categorization that emerged during the review to select and analyze the texts. We found several issues that seem to condition mathematics learning in boys that have to do with gender and specific identity construction, namely the dominant traditional masculinities. Moreover, this process is enhanced by the social attraction towards violence processes. However, the literature also contains elements that respond to a different model of masculinity that can be successful in mathematics learning and attractive at the same time, which is related to the New Alternative Masculinities model. We conclude with some recommendations to support this new and attractive model and to rethink research in mathematics achievement in children in the future.
