Metasurfaces and their applications
Authors: Li Aobo , Singh Shreya , Sievenpiper Dan 
Published: June 2018

AbstractMetasurfaces are a topic of significant research and are used in various applications due to their unique ability to manipulate electromagnetic waves in microwave and optical frequencies. These artificial sheet materials, which are usually composed of metallic patches or dielectric etchings in planar or multi-layer configurations with subwavelength thickness, have the advantages of light weight, ease of fabrication, and ability to control wave propagation both on the surface and in the surrounding free space. Recent progress in the field has been classified by application and reviewed in this article. Starting with the development of frequency-selective surfaces and metamaterials, the unique capabilities of different kinds of metasurfaces have been highlighted. Surface impedance can be varied and manipulated by patterning the metasurface unit cells, which has broad applications in surface wave absorbers and surface waveguides. They also enable beam shaping in both transmission and reflection. Another important application is to radiate in a leaky wave mode as an antenna. Other applications of metasurfaces include cloaking, polarizers, and modulators. The controllable surface refractive index provided by metasurfaces can also be applied to lenses. When active and non-linear components are added to traditional metasurfaces, exceptional tunability and switching ability are enabled. Finally, metasurfaces allow applications in new forms of imaging.

Published: June 2018

AbstractEmpirical investigations of solute fate and carrying in streams and rivers often contain inventive liberate of solutes at an upstream perimeter for a finite interval of time. An analysis of various worth references on surface-water-grade mathematical formulation reveals that the logical solution to the continual-parameter advection- dispersion problem for this type of boundary state has been generally missed. In this work, we study theq-fractional homotopy analysis transform method (q-FHATM) to find the analytical and approximate solutions of space-time arbitrary order advection-dispersion equations with nonlocal effects. The diagrammatical representation is done by using Maple package, which enhance the discretion and stability of family ofq-FHATM series solutions of fractional advection-dispersion equations. The efficiency of the applied technique is demonstrated by using three numerical examples of space- and time-fractional advection-dispersion equations.

Authors: Alkenani Ahmad N. , Ashraf Mohammad , Jabeen Aisha 
Published: June 2018

Abstract
Let R be a commutative ring with identity element, A and B be unital algebras over R and let M be (A,B)-bimodule which is faithful as a left A-module and also faithful as a right B-module. Suppose that A = Tri(A,M,B) is a triangular algebra which is 2-torsion free and σ, Γ be automorphisms of A. A map δ:A→A (not necessarily linear) is called a multiplicative generalized (σ, Γ)-derivation (resp. multiplicative generalized Jordan (σ, Γ)-derivation) on A associated with a (σ, Γ)-derivation (resp. Jordan (σ, Γ)-derivation) d on A if δ(xy) = δ(x)r(y) + σ(x)d(y) (resp. σ(x<sup>2</sup>) = δ(x)r(x) + δ(x)d(x)) holds for all x, y Є A. In the present paper it is shown that if δ:A→A is a multiplicative generalized Jordan (σ, Γ)-derivation on A, then δ is an additive generalized (σ, Γ)-derivation on A.

Authors: Carrillo-Pacheco Jesús , Jarquín-Zárate Fausto 
Published: June 2018

Abstract
The aim of this paper is twofold. First, we show a connection between the Lagrangian- Grassmannian variety geometry defined over a finite field with q elements and the q-ary Low-Density Parity- Check codes. Second, considering the Lagrangian-Grassmannian variety as a linear section of the Grassmannian variety, we prove that there is a unique linear homogeneous polynomials family, up to linear combination, such that annuls the set of its rational points.
Abriendo closings in bilingual radio speech: Discourse strategies, code-switching, and the interactive construction of broadcast structures and institutional identity
Authors: Tseng Amelia 
Published: June 2018

AbstractRadio highlights the linguistic construction of institutional identity: it privileges presenter speech, as DJs use language to represent not only the self but also the show, and ultimately the station’s identity to the listening audience for commercial purposes. The relationship between show structure and stylistic practice in interaction offers insights into identity construction and audience relationships in institutional settings. This qualitative study investigates the linguistic construction of closing sequences in bilingual radio discourse, examining the relationship between DJ speech and the interactional construction of closing structures in 18 report- and chat-genre closings from 95.1 Latino Vibe. Findings indicate that closing structures are genre-specific, with the less-formal chat genre integrating elements of media and conversational closings. Code-switching is genre-sensitive and plays a multifaceted functional, relational, and representational role, ranging from constructing show structures to audience affiliation and a formulaic type of “verbal branding.” Ultimately, closing sequences and code-switching relate to broader institutional goals of station representation and audience engagement. The article sheds light on the relationship between interaction-level discourse moves, institutionalized identity construction, and the development of interactional structures through talk; and highlights the added dimensions that bilingual speech strategies contribute to these practices.

Published: June 2018

Context
Von Hippel–Lindau (VHL) disease manifests as a variety of benign and malignant neoplasms. Previous studies of VHL disease have documented several genotype–phenotype correlations; however, many such correlations are still unknown. Increased identification of new mutations and patients with previously described mutations will allow us to better understand how VHL mutations influence disease phenotypes.

Patients and design
A total of 45 individuals from five unrelated families were evaluated, of which 21 patients were either diagnosed with VHL disease or showed strong evidence related to this disease. We compared the patients’ gene sequencing results with their medical records including CT or MRI scans, eye examinations and laboratory/pathological examinations. Patients were also interviewed to obtain information regarding their family history.

Results
We identified four missense mutations: c.239G>T (p.Ser80Ile), linked with VHL Type 2B, was associated with renal cell carcinoma, pheochromocytoma and hemangioma in the cerebellum; c.232A>T (p.Asn78Tyr) manifested as RCC alone and likely caused VHL Type 1; c.500G>A (p.Arg167Gln) mutation was more likely to cause VHL Type 2 than Type 1 as it preferentially induced Pheo and HB in the retina, cerebellum and spinal cord; c.293A>G (p.Try98Cys) was associated with Pheo and thus likely induced VHL Type 2.

Conclusions
Characterizing VHL disease genotype–phenotype correlations can enhance the ability to predict the risk of individual patients developing different VHL-related phenotypes. Ultimately, such insight will improve the diagnostics, surveillance and treatment of VHL patients.

Precis
Four missense mutations in VHL have been identified in 21 individuals when five unrelated Chinese families with VHL disease were analyzed; VHL mutations are highly associated with unique disease phenotypes.
Idiomaticidade, familiaridade e informação prévia no processamento de expressões idiomáticas do PB
Authors: De Oliveira Gomes Barreto Sara , Marcilese Mercedes , Avelar de Oliveira Ágata Jéssica 
Published: June 2018

Expressões idiomáticas são comumente caracterizadas como combinações fixas e não-composicionais nas quais o sentido figurado não constitui uma função da soma das partes; seu grau de composicionalidade, entretanto, é variável. Este artigo investiga a compreensão de expressões idiomáticas do tipo verbo-complemento no português brasileiro (ex. “pintar o sete”, “passar a bola”). Buscamos avaliar em que medida propriedades internas e externas das expressões podem influenciar no processamento das mesmas. Reportamos os resultados de um experimento de leitura automonitorada (conduzido por meio de uma maze task), no qual o segmento crítico corresponde à complementação do verbo: idiomático vs. literal (ex. abrir o coração/ a porta). Os resultados revelaram efeitos estatisticamente significativos das três variáveis investigadas, sugerindo que o grau de idiomaticidade, a familiaridade do falante com a expressão e a informação prévia afetam o processamento das expressões e, portanto, devem ser considerados num modelo que busque explicitar a representação, o acesso e a compreensão dessas estruturas.
Estimulação da consciência fonológica na Síndrome de Down
Authors: Porcellis Maria Eugênia Da Fontoura , Lorandi Aline , Lorandi Melina 
Published: June 2018

O presente estudo objetivou avaliar e estimular a consciência fonológica em indivíduos com síndrome de Down. Os 24 participantes, divididos em três grupos, foram testados em suas habilidades de consciência fonológica e, em seguida, os grupos experimentais (um com desenvolvimento típico e um com síndrome de Down) realizaram um programa de estimulação dessas habilidades que teve a duração de seis semanas. Como resultado, os dois grupos experimentais foram significativamente melhores no pós teste, devido à eficiência da estimulação, e apresentaram melhor desempenho que o grupo controle (sem a síndrome). Além disso, o grupo com síndrome de Down, após a estimulação, obteve um aprimoramento superior que o grupo experimental sem a síndrome, provavelmente por terem realizado as atividades individualmente. Destaca-se o fato de que as atividades de estimulação foram especialmente desenvolvidas em função das dificuldades de memória, de atenção e de linguagem expressiva normalmente vinculadas à síndrome. Algumas reflexões sobre opções metodológicas são sugeridas em relação à avaliação e ao ensino de populações atípicas.
Envelhecimento sadio, Comprometimento Cognitivo Leve e doença de Alzheimer: um estudo das estratégias comunicativas na narrativa oral
Authors: Jerônimo Gislaine Machado 
Published: June 2018

O aumento de casos de Comprometimento Cognitivo Leve (CCL) e de doença de Alzheimer (DA) leva ao questionamento sobre as habilidades cognitivas e linguísticas comprometidas. A literatura, de modo geral, aborda os prejuízos na comunicação destas populações, sendo pouco investigadas as habilidades preservadas. Assim, este estudo objetiva analisar as estratégias comunicativas (ECs) presentes na produção de narrativa oral desses indivíduos, bem como verificar o impacto da variável escolaridade no esempenho da mesma atividade em idosos saudáveis. Participaram do estudo 95 idosos, os quais produziram uma narrativa oral baseada em uma sequência de figuras, The Dog Story (LE BOUEF, 1976). Os resultados mostraram que idosos com CCL e DA fizeram mais uso de ECs do que o grupo controle, ao passo que idosos saudáveis com alta escolaridade utilizaram menos. Portanto, as ECs mostraram-se um apoio à comunicação no CCL e na DA, assim como a escolaridade evidenciou-se um importante marcador de reserva cognitiva no envelhecimento sadio.
“Pornographic binges” as a key characteristic of males seeking treatment for compulsive sexual behaviors: Qualitative and quantitative 10-week-long diary assessment
Authors: Wordecha Małgorzata , Wilk Mateusz , Kowalewska Ewelina , Skorko Maciej , Łapiński Adam , Gola Mateusz 
Published: June 2018

Background and aims
Compulsive sexual behaviors (CSBs) are an important clinical and social issue. Despite the increasing number of studies, some of CSB’s aspects remain under-investigated. Here, we explore the nature of CSB, such as binge pornography use and masturbation (PuM), and verify the correspondence between self-perceived factors leading to such behavior with its measures obtained in a diary assessment.

Methods
Semi-structuralized interviews with nine treatment-seeking males aged 22–37 years (M = 31.7, SD = 4.85) were followed by a questionnaire and a 10-week-long diary assessment, allowing us to acquire real-life daily patterns of CSB.

Results
Six out of nine subjects experienced binge (multiple hours or times a day) PuM. All subjects presented a high level of anxiety and perceived PuM as a way to regulate mood and stress. Data collected in the diary assessment uncovered a high diversity in the patterns of sexual behaviors (such as frequency of regular and binge PuM) and its correlates. Binge PuM was related to decreased mood and/or increased stress or anxiety. The causal relation between these correlates remains undetermined.

Discussion and conclusions
Binge PuM seems to be one of the most characteristic behavior among males who are seeking treatment for CSB and is related to the feeling of losing control over one’s sexual activity. CSB individuals indicate a variety of binge triggers. Also, diary assessment data indicate that specific correlates of binge PuM (decreased mood, increased stress, and anxiety) differ between subjects. It suggests the existence of significant individual differences in binge PuM behaviors, and a need to study these differences, as it may help guide personalized treatment.

Published: June 2018

The pathology of upper lacrimal pathways associated with cicatrical strictures and obliteration, anatomical features of this zone is an essential problem of epiphora occurrence. The diseases of nasal cavity and paranasal sinuses play a significant role in the etiopathogenesis of this kind of epiphora. The search of new methods of preventing or eliminating epiphora, also caused by rinological pathology, is reasonable.
Aim: To estimate the efficacy of drainage implant HEALAFLOW (Aptissen, Switzerland) in patients with complains on epiphora and concomitant nasal cavity pathology.
Material and methods. 29 patients (50 eyes) with complains on permanent (more than 6 months) epiphora were under the supervision. Ge nerally accepted ophthalmological, dacryological, rhinological examinations, including cone-ray computer tomography of the paranasal sinuses with preliminary contrast of the lacrimal pathways were carried out. Patients were divided into two groups. 15 people (28 eyes) composed the main group (I). 14 people (22 eyes) formed a control group (II). In I group the drainage implant HEALAFLOW (Aptissen, Switzerland) was inserted in 1 day after operation aimed on elimination of nasal cavity pathology. Patients of the II group instillation of Tobradex according to the scheme and moistening drops were prescribed.
Results. According to dacryological examination 29 patients (50 eyes) with complains on epiphora had normal passive lacrimal pathway passablness, but delayed or negative results of probes characterizing active passablness. All 29 patients had a rhinological pathology, which was eliminated by the otorhinolaryngologist with the operation at the first stage. In I group 9 patients noticed an increased epiphora immediately after the administration of HEALAFLOW in lacrimal pathway, which lasted during the first 24 hours after the procedure. Based on the results of the follow-up examination, after 3 months, all patients showed an improvement, expressed in the absence or decrease of epiphora. It should be noted that in the I group (after the insertion of the implant) the positive effect was more expressed. In the I group 12 of 15 patients didnt have epiphora and in 3 patients it decreased. In the II group 7 patients didnt have epiphora and in 6 patients it decreased.
Conclusion. Insertion of drainage implant HEALAFLOW in the lacrimal pathway after elimination of rhinological pathology in patients with complains on epiphora is safe, well tolerated and produces a positive drainage effect. This allows to recommend the implant to patients with tear-off device abnormality in the complex treatment of tear outflow disorders.
An educational perspective on the philosophy of Petre Paul Negulescu (1872â€“1951) at the Romania Centennialâ€™s (1918â€“2018)
Authors: Avram Virtop Sorin 
Published: June 2018

A disciple of Titu Maiorescu (1840â€“1917), Petre Paul Negulescu, along with Constantin Radulescu-Motru (1868â€“1957) and Ion Petrovici (1882â€“1972), is regarded as being among the most prolific thinkers in Romanian modern thought and one of the founders of the modern Romanian culture. Historical changes he could never envisage have left their mark upon the perception, reception and interpretation of his work. The paper reviews the key characteristics of Petre Paul Negulescuâ€™s work as reflected in his studies on the origin of culture, the philosophy of Renaissance and two magnificent works, The History of Contemporary Philosophy and The Destiny of Humanity. The aim is to contextualise these works within the field of philosophy in terms of their sources, conceptual approach and hermeneutics. As well as furnishing the Romanian culture with a wealth of original thought, his pertinent analysis of social, economic, cultural and political changes, and his involvement in improving the educational system through his position as Minister of Instruction, have made him worthy of criticism and an outstanding reference point in times of revival.
