In this work we present a simple transfer-matrix based modeling tool for arbitrarily layered stacks of resonant plasmonic metasurfaces interspersed with dielectric and metallic multilayers. We present the application of ...

Based on many years of experience in the organization of the third stage of Ukrainian National Astronomy Olympiad, the authors of the article attempt to formulate general principles for the selection and compilation of a...

Abstract Background The COVID-19 pandemic has affected all sectors of the world economy and society. To understand the impact of the pandemic on firms in China and suggest public policies to deal with the negative effect...

With their ultrathin characteristics as well as the powerful and flexible capabilities of wavefront modulation, optical metasurfaces have brought a new understanding of the interaction between light and matter and provid...

As a new member of saturable absorber (SA), molybdenum carbide (Mo2C) has some excellent optical properties. Herein, we report a new type of Mo2C/fluorine mica (FM) SA device. Uniform and compact Mo2C films were deposite...

Abstract Most gear fault diagnosis (GFD) approaches suffer from inefficiency when facing with multiple varying working conditions at the same time. In this paper, a non-negative matrix factorization (NMF)-theoretic co-cl...

Abstract Objective Streptococcus agalactiae is an important pathogen in neonates and pregnant women. Neonatal invasive infections due to S. agalactiae are life-threatening and preventive strategies for this challenge o...

Background The novel coronavirus disease 2019 (COVID-19) pandemic has given rise to fear and panic in the public. Although hospitals in China reduced outpatient visits and restricted inpatient admission to lower the risk...

Relevance. Training systems which are based on the principle of apprenticeship and involve the company as a central venue are gaining in significance in international terms. The fundamental recognition here is, “Appren...

Carbon nanotubes (CNTs) possess remarkable nonlinear optical properties; a particular application is to function as a mode locker used in ultrafast fiber lasers to produce ultrashort optical pulses. Various types of CNT ...

Abstract Myasthenia, a syndrome of impaired neuromuscular transmission, occurs as either an acquired or congenital condition. Myasthenia gravis (MG) is an acquired autoimmune disorder with autoantibodies against the neur...

Abstract Current research concerning legged platforms and wheeled platforms primarily focuses on terrain adaptive capability and speed capability, respectively. Compared with wheeled platforms, legged platforms with a cl...

Abstract The use of instant messaging affects different areas of users’ daily lives (personal, social, family, work). The aim of this research was to develop and validate a scale that measures the negative impact of Wh...

Strong field confinement, long-lifetime resonances, and slow-light effects suggest that metasurfaces are a promising tool for nonlinear optical applications. These nanostructured devices have been utilized for relatively...

Abstract In this study, quali-quanti methodology was applied to analyze the implementation of Law no. 12,990/2014 on quotas for Black candidates at 63 federal universities and 38 federal ‘institutes’ (secondary and v...

Tadeusz Zieliński was an outstanding scholar specialising in Greek and Roman literature as well as an accomplished orator, though nowadays he is not always appreciated. The best example of his vast knowledge and oratori...

This study provides empirical evidence on income smoothing from the banking sector in nine South-Eastern Europe (SEE) countries for the period 2005-2014 by applying a number of methodological approaches. First, by usin...

The manipulation of magnetization in a metallic ferromagnet by using optical helicity has been much attracted attention for future opto-spintronic devices. The optical helicity–induced torques on the magnetization, opt...

Abstract This article analyses the co-ordination between national and municipal governments in Brazil regarding migration policy between the years of 2013 and 2016, using the concept of policy institutional arrangements ...

Abstract Soil samples collected near municipal schools (public/EMEI and private/EPEI schools), clubs (CLB), public squares (PS) and residential condominiums (CND) and samples of animal faeces from the Zoonosis Control Ce...

Abstract Background Chronic neuropathic pain is a common complication in people with spinal cord injury (SCI) but has not been investigated in dogs. Objective To determine the reliability of measuring spinal mechanical s...

We propose a radio frequency (RF) and visibly transparent composite metasurface design comprising newly developed transparent multilayer conductive coatings. Detailed experimental and theoretical analysis of the RF/visib...
