Abstract:

In this paper, we present a new class of sextic trigonometric Bernstein (ST-Bernstein, for short) basis functions with two shape parameters along with their geometric properties which are similar to the classical Bernstein basis functions. A sextic trigonometric Bézier (ST-Bézier, for short) curve with two shape parameters and their geometric characteristics is also constructed. The continuity constraints for the connection of two adjacent ST-Bézier curves segments are discussed. Shape control parameters can provide an opportunity to modify the shape of curve as designer desired. Some open and

Abstract:

This research note examines the relationship between economic development and gender equality. Drawing on the concept of the Kuznets curve, the authors hypothesize that the relationship between economic development and gender inequality is curvilinear (S shaped), with three distinct stages. In the first stage, economic development improves gender equality because it enables greater female labor-force participation. An independent income stream increases women's intrahousehold bargaining power. The opportunity to develop human capital confers greater political and social recognition. In the sec

Abstract:

The problem of modelling a smooth contour with a regular change in curvature representing a monotone curve with specified accuracy is solved in this article. The contour was formed within the area of the possible location of a convex curve, which can interpolate a point series. The assumption that if a sequence of points can be interpolated by a monotone curve, then the reference curve on which these points have been assigned is monotone, provides the opportunity to implement the proposed approach to estimate the interpolation error of a point series of arbitrary configuration.

The model considers roadway alignment in three dimensions. The mode

Abstract:

Economic theory is prone to hysteresis. Once an idea is adopted, it is difficult to change. In the 1970s, the economics profession abandoned the Keynesian Phillips curve and adopted Milton Friedman's natural rate of unemployment (NRU) hypothesis. The shift was facilitated by a series of lucky breaks. Despite much evidence against the NRU, and much evidence and theoretical argument supportive of the Keynesian Phillips curve, the NRU hypothesis remains ascendant. The hypothesis has had an enormous impact on macroeconomic theory and policy. 2018 is the 50th anniversary of Friedman's introduction

We shall describe a corrected constant. We also take the opportunity to extend the scope of the original conjecture to ask how often |E(𝔽p)|/t is an integer and prime for a fixed positive integer t, and to consider elliptic curves over arbitrary number

Abstract:

Extraordinary occurrence of the solar eclipse offers opportunity to evaluate spectral characteristic changes and intensities of daylighting during its various phases. Changes of the daylight spectrum in positions: zenith and 45° above horizon with orientation of sensors opposite to sun position were measured. Changes of horizontal illuminance and luminance as well as changes of the correlated colour temperature in the range of the Planck curve were measured in Bratislava and evaluated. Paper presents results of experimental measurements and discusses in point of view of sunlight characteristic

Abstract:

Liquid biopsy (LB) is a non-invasive approach representing a promising tool for new precision medicine strategies for cancer treatment. However, a comprehensive analysis of its reliability for pancreatic cancer (PC) is lacking. To this aim, we performed the first meta-analysis on this topic. We calculated the pooled sensitivity, specificity, positive (LR+) and negative (LR−) likelihood ratio, and diagnostic odds ratio (DOR). A summary receiver operating characteristic curve (SROC) and area under curve (AUC) were used to evaluate the overall accuracy. We finally assessed the concordance rate of

Abstract:

The number of female owned enterprises is gradually increasing as more and more women are starting their own businesses. This has encouraged, governments, policy makers, and scholars to focus on unearthing different individual, social, and economic factors, which can promote female entrepreneurial activities. However, a majority of the studies concerning female entrepreneurial activities have focused on their overall level of business start-ups. These studies have failed to delineate between necessity based and opportunity driven entrepreneurship. Moreover, little empirical work is done to inv

ABSTRACT Semidetached eclipsing systems provide a unique opportunity to derive the basic properties of interacting binaries. The goal of this work is to collect and to make use of data on semidetached systems with available light and radial velocity curve solutions. I have compiled the most comprehensive list to date, of 119 semidetached double-lined eclipsing binaries, containing the orbital parameters and physical parameters of the components. I consider the classification of semidetached binaries and discuss gaps between various classes in the Hertzspung–Russell diagram. I list systems with

Abstract:

On 21st September, 2016, the Bank of Japan (BOJ) embarked on a new unconventional monetary policy called yield curve control (YCC). We show that YCC creates an arbitrage opportunity in an otherwise frictionless and arbitrage-free government bond market which financial institutions can exploit. This arbitrage creates a wealth transfer from the BOJ to these financial institutions. We estimate the lower bound on this wealth transfer for the first 28 months to be $5.25 billion or [Formula: see text]582.32 billion, which constitutes an unexplored policy externality. This corresponds to 7.49% per an

A single-board computer based embedded system has fully supported SSL communication, but it costs a very high price. On the other hand, STM32F103 microcontrollers with a very affordable

Background: The topic of Magnetic Levitation systems, in terms of land mass transport, have created high expectations compared to aviation and also to the high speed railway industry. This new concept comes to revolutionize the terrestrial mass transport, in both the speeds and the subject of friction. Magnetic levitation solves the issue of attrition between material contact and as such may also be an opportunity to solve the question of constant physical superelevation. Aim: Precisely that point of superelevation coupled with magnetic levitation, eliminating the rigid physical structur

Abstract:

Utility-based studies are attractive to zooarchaeologists because they afford the opportunity of investigating economic decisions relative to particular contexts. While a positive relationship between utility and skeletal element abundance is anticipated at residential sites, a reverse utility curve is most common. A popular mechanistic explanation argues that reverse utility curves result from density-mediated destruction of bone, suggesting that utility-based studies will rarely be successful as density-mediated destruction will overwhelm any skeletal element patterning created by differenti

Abstract:

ABSTRACT AT 2018cow is a unique transient that stands out due to its relatively fast light curve, high peak bolometric luminosity, and blue colour. These properties distinguish it from typical radioactively powered core-collapse supernovae (SNe). Instead, the characteristics are more similar to a growing sample of Fast Blue Optical Transients (FBOTs). Mostly discovered at hundreds of Mpc, FBOT follow-up is usually limited to several photometry points and low signal-to-noise spectra. At only ∼60 Mpc, AT 2018cow offers an opportunity for detailed follow-up. Studies of this object published to da
