2. Frequency Reconfigurable Near-Zero Refractive Index Material for Antenna Gain Enhancement Applications
Abstract In this paper, a planar near-zero refractive index material (NZRIM) consisting of an outer loop with four symmetrical quarter-rings is proposed. The quarter-rings are connected to the outer loop by two symmetrical microstrip lines on the opposite side. The backside of the substrate has mutually central split microstrip lines. By loading adjustable c

3. MIMO-PLC Communications in an Experimental Medium Voltage Network: Measurement and Analysis
Abstract This paper presents measurements at a mock-up medium voltage network to verify the feasibility of Broadband Power Line Communication (BPLC). We use the data extracted within the frequency range 2 − 30 MHz to characterize a MIMO PLC network using different phase combinations, defining the best and worst use case scenarios. The empirical data shows

5. The Military Orders, the Muslim World, and the Dilemmas of Conviviality: Connected Histories as a Critical Approach to the History of the Crusades
Resumo Este artigo explora as potencialidades do método das Histórias Conectadas para o estudo das Cruzadas e, mais especificamente, das Ordens Militares. O corpus tomou forma, inicialmente, em um documento papal de 1179, que listava as disputas entre os Templários e os Hospitalários. Nele, encontramos comunidades itinerantes sob o cuidado do Templo. Tam

6. Percutaneous tracheostomy in COVID-19 patients: a new apneic approach
Abstract Background: Percutaneous dilation tracheostomy is an aerosol-generating procedure carrying a documented infectious risk during respiratory virus pandemics. For this reason, during the COVID-19 outbreak, surgical tracheostomy was preferred to the percutaneous one, despite the technique related complications increased risk. Methods: We describe a ne

7. The Endoscopic Anatomy of the External Acoustic Meatus and of the Middle Ear in Dry Temporal Bones: A Study Conducted Using Digital and Mobile Device Technology
Abstract Introduction The endoscopic anatomy of the middle ear (ME) and of the external acoustic meatus (EAM) has been described in cadavers, in fresh temporal bones, or in vivo using conventional video recording, but not in dry bones or using an alternative inspection and recording technique. Objective To study the anatomy of the ME and of the EAM in dry

8. Numerical formulation for nonlinear analysis of concrete and steel shells with deformable connections
Abstract A two-dimensional interface finite element capable of associating flat shell elements positioned one above the other was developed. The implemented interface element can physically simulate the contact between the flat shell elements and connect the reference planes of the shell elements above and below it. The formulation presented allows considera

9. WHAT’S VOLUNTARY IN STANCE VOLUNTARISM?
Abstract Stance voluntarism highlights the role of the will in epistemic agency, claiming that agents can control the epistemic stances they assume in forming beliefs. It claims that radical belief changes are not compelled by the evidence; they are rationally permitted choices about which epistemic stances to adopt. However, terms like “will”, “choice

10. Novel Design of a Hybrid Superconducting Fault Current Limiter with Controlled Solid-State Device
Abstract Fault current limiters are essential devices used to protect the power system and its equipment against high levels of fault current, which are growing up due to the increase of new power sources. This paper proposes a novel design of a Hybrid Superconducting Fault Current Limiter (Hybrid SFCL), which is composed basically by thyristors in series wi

11. Expedient Microwave-Assisted Synthesis of Bis(n)-lophine Analogues as Selective Butyrylcholinesterase Inhibitors: Cytotoxicity Evaluation and Molecular Modelling
In the brain of patients with chronic Alzheimer’s disease (AD), the butyrylcholinesterase (BuChE) levels rise while the acetylcholinesterase (AChE) levels decrease. Therefore, development of new selective BuChE inhibitors is of vital importance. Here we present a series of bis(n)-lophine analogues, where two lophine derivatives are connected by a methylene
