Cylindrical vector beams with polarization singularities, transmission stability and turbulence resilient, are orthogonally structured light beams providing new degrees of freedom for multiplexing optical communications....

Background/Aim: To investigate the relationship of the -799C/T (rs11225395) and -381A/G (rs1320632) matrix metalloproteinase 8 (MMP8) gene polymorphisms with periodontitis and the levels of active MMP-8 (aMMP-8) in an or...

Abstract Introduction There are several negative impacts on the physical and mental health of people presenting internet addiction, including development of mood disorders, such as depression. Objective The aim of th...

The paper presents the results of computer modeling of the proposed functional-electrical circuit of integrated signal converters (ISC) from photosensitive elements based on CMOS operational amplifiers, which is intended...

ABSTRACT Due the tolerance in soil degraded, Eucalyptus is widely used in reforestation area. This study aims to evaluate the fungi that use Eucalyptus grandis W. Hill ex Maiden as substrate in reforestation area in sout...

This study statistically examined the industrial cluster structure of four cities in the Tohoku region (Yonezawa, Koriyama, Iwaki, and Aizuwakamatsu) in terms of the relationship between each industry and the total value...

Resumo Objetivo Identificar na literatura científica as barreiras que dificultam a aplicação da Lista de Verificação para Partos Seguros da Organização Mundial da Saúde. Métodos Revisão integrativa, realiza...

Lithium niobate Mach–Zehnder modulators (MZMs) with compact footprint and fast electro-optics (EO) responses are highly demanded for the next-generation optical interconnect systems. Here, we demonstrate slow-light (SL...

Abstract Numerical and experimental analysis of visible light communication (VLC) systems based on orthogonal chirp division multiplexing (OCDM) and orthogonal frequency division multiplexing (OFDM) are presented in this...

Abstract The current research of abrasive belt grinding rail mainly focuses on the contact mechanism and structural design. Compared with the closed structure abrasive belt grinding, open-structured abrasive belt grindin...

ABSTRACT Fusarium head blight, also known as fusariosis, is caused by a fungus called Fusarium graminearum that produces the mycotoxin deoxynivalenol (DON). This toxin causes problems to human and animal health. Ammonia ...

The role of the early warning system by the KP2C Community in providing information on flood disasters that often occur in the Cileungsi – Cikeas watershed really helps the community in reducing the impact of the unavo...

A method for direct fabrication of 3D silver microstructures with high fabrication throughput on virtually any substrate is presented. The method is based on laser-induced photoreduction of silver ions to silver atoms, s...

Abstract In this essay I defend the view that dogwhistling is a a speech act performed with a narrative-evoking perlocutionary effect in the so-called target audience. What is evoked is a certain kind of narrative, previ...

Resumo A cultura digital impacta a relação dicotômica entre ambientes físicos e on-line. O cenário sociotécnico da educação ainda está descompassado em relação às competências digitais e é socialmente segre...

Exceptional points (EPs) are degenerate singularities in a non-Hermitian system that can be induced by controlling the interaction between resonant photonic modes. EPs can enable unusual optical phenomena and significant...

Active metasurfaces designed to operate at optical frequencies are flat optical elements that can dynamic, subwavelength-scale wavefront control of reflected or transmitted light. The practical and fundamental power-hand...

Introduction: Broca’s aphasia, a non-fluent aphasia, is a frustrating condition with extensive psychological, familial, and social impact. The reports of people who have already recovered or can express themselves are ...

Abstract The frequency of gastrointestinal parasites with an emphasis on Strongylus vulgaris was investigated among the Brazilian Pony breed kept on farms in the municipality of Teresópolis, state of Rio de Janeiro. Fec...

This work synthesized a thermoplastic polymer with varying densities along one direction using additive manufacturing technology to study the dynamic and static characteristics of functionally graded viscoelastic materia...

PbS colloidal quantum dots (CQDs) can be considered a promising lighting material, but their emission performance is mired by defect sites, strong photo-induced activity, and interaction with the environment. Here, we ut...

Solving optimal control problems serves as the basic demand of industrial control tasks. Existing methods like model predictive control often suffer from heavy online computational burdens. Reinforcement learning has sho...

The demand on broadband near-infrared photodetections with high responsivity is becoming increasingly eminent; however its realization remains a significant technological challenge. Here we design, fabricate, and charact...
