Optical phased arrays (OPAs) hold significant promise for low-cost, solid-state beam steering in LiDAR and free-space optical (FSO) communications. The field of view (FOV) is one of the key performance metrics in OPA for...

A semi-analytical formalism for the optical properties of a metal-insulator-metal periodic nanostructure using coupled-mode theory is presented. This structure consists in a dielectric layer in between two metallic layer...

This classroom action research examined whether the Teaching at the Right Level (TaRL) approach could improve fourth-grade students' learning outcomes in IPAS, especially on the topic of ethnic and cultural diversity, at...

Liquid crystalline polyurethanes (LCPUs), having azobenzene mesogenic groups, formed a nematic phase on heating and cooling processes. Liquid crystalline binary mixtures were obtained by mixing LCPUs and strongly polar c...

War and the hybrid threat are two types of activities legally differentiated only by the word „war”. They aim at exploiting and generating vulnerabilities of the target states and have become areas of reflection to i...

El campo de la política es y ha sido en un sentido decisivo y radical, un producto de la creación humana. La forma que tenemos de pensar las actividades que identificamos como políticas o los conceptos que utilizamos ...

Abstract For vehicle tactical radio communications, positioning antennas along the structure is a complex task. In vessels, there are several radio systems installed operating from HF to SHF. Consequently, the antennas n...

Finite-size effects occurring for quasi-bound states in the continuum (qBICs) formed in symmetric and asymmetric all-dielectric waveguide grating couplers are investigated using numerical simulations for different config...

Abstract The present article sets out to analyze instances of racial discourse circulating in both the Brazilian and international media during a particular time of crisis - the Covid 19 pandemic - and follows this analy...

Abstract The recent cataloging of global microseisms benefits imaging of the Earth's interior with improved data coverage. Relying on the catalog, converted waves were extracted and employed to reveal variations of the m...

Education in Poland and Ukraine are deeply-rooted in multiculturalism, regionalism and patriotic tradition. In the past, these notions were associated with nobility and great national matters. In the era of democratizati...

Este artigo propõe, na primeira parte, uma reflexão baseada nas dificuldades encontradas no âmbito dos Institutos Universitários de Formação de Professores - IUFMs -, na França, para articular de maneira eficaz os...

This discourse-based study investigated semantic and affective aspects of metaphors used by people talking about background risk of terrorism. 96 members of the UK public participated in 12 focus group discussions, organ...

Abstract Background Intern physicians, in the final stage of medical training, face increasing clinical responsibility and workload, which may heighten vulnerability to errors and second victim experiences. This study ai...

My reflections on this theme are based on the experiences of Argentina. In some aspects, but not all, these reflections also refer to Latin America as a region. In Latin America, social movements, political leaders, and ...

Abstract This paper presents the influence of different sizes of carbonyl iron particles on the reflectivity measurements of Radar Absorbing Material (RAM). The electromagnetic characterization was performed with a vecto...

This study employs the transfer matrix method combined with numerical simulations based on the transfer matrix model and an impedance tube testing system to explore the correlation mechanism of acoustic parameters in Lig...

This practice report describes the development of a compensatory educational model to introduce first-year college students to resilient mindsets. The Teaching Resilient Mindsets Model emphasized (1) realistic expectatio...

This article discusses the relation between politics, religion, and science, as understood by the nineteenth-century French socialist Claude-Henri de Saint-Simon and described in his project of European Union. We find in...

Abstract BackgroundMany persons with type 2 diabetes (T2D) lack risk awareness or underestimate their cardiovascular risk. Although health care professionals in primary health care strive to implement risk-aw...

ABSTRACT This article presents a qualitative study which aimed at investigating the process of identity construction of Silvana, an English language teacher from the Federal Institute of Santa Catarina (IFSC). In order t...

Many nations historically identifying as secular are now transitioning into post-secular societies in which multiple, competing religious and ideological voices shape public life. This shift creates the possibility that ...

This study aimed to discuss the use of the race/color variable as a determining factor of social difference and social exposure to the risk of illness and death. It is a reflection on the present production of the nation...

Abstract Background Volatile anesthetics are widely used for sedation in intensive care. Being potent greenhouse gases, their efficient utilization is imperative. We investigated whether the efficiency of anesthetic refl...
