Exact behavior around isolated singularity for semilinear elliptic equations with a log-type nonlinearity
Authors: Ghergu Marius , Kim Sunghan , Shahgholian Henrik
Published: June 2018

We study the semilinear elliptic equation

-\Delta u=u^{\alpha}\lvert\log u|^{\beta}\quad\text{in }B_{1}\setminus\{0\},

where

{B_{1}\subset{\mathbb{R}}^{n}}

, with

{n\geq 3}

,

{\frac{n}{n-2}<\alpha<\frac{n+2}{n-2}}

and

{-\infty<\beta<\infty}

.
Our main result establishes that the nonnegative solution

{u\in C^{2}(B_{1}\setminus\{0\})}

of the above equation either has a removable singularity at the origin or it behaves like

u(x)=A(1+o(1))|x|^{-\frac{2}{\alpha-1}}\Bigl{(}\log\frac{1}{|x|}\Big{)}^{-%
\frac{\beta}{\alpha-1}}\quad\text{as }x\rightarrow 0,

with

{A=[(\frac{2}{\alpha-1})^{1-\beta}(n-2-\frac{2}{\alpha-1})]^{\frac{1}{\alpha-1%
}}.}
Biorthogonal wavelet codes with prescribed code distance
Authors: Soloviev Alexander A. , Chernikov Dmitry V.
Published: June 2018

We propose a scheme of construction of 2-circulant codes with given code distance on the basis of biorthogonal filters with the property of perfect reconstruction over a finite filed of odd characteristic. The corresponding algorithm for constructing biorthogonal filters utilizes the Euclidean algorithm for finding the gcd of polynomials.
Technological Innovation and Product Market Conditions: R&D Rivalry, Market Competition, and Customer Satisfaction
Authors: Choi Kyeong-Seop
Published: June 2018

With regard to research and development (R&D), corporate finance tends to be too broad, whereas marketing tends to be too specific. Using the marketing–finance interface, new R&D expenditure variables are constructed to reflect industry rivalry by incorporating industry-year median and standard deviation. Market competition and customer satisfaction are also included in the regression. Dynamic generalized-method-of-moments regressions based on US data provide subversive results. Sales and cash flow, which are reported in prior literature to be associated with R&D investment, were insignificant. Leverage, known as detrimental to investment in intangible assets, such as R&D, contributed to rivalrous and strategic R&D investments. Of course, high market-to-book ratios encourage such R&D investments. However, in high-tech industries, market competition absorbs all other influences on R&D, though the impact of market competition on R&D is negative. We also expect that while high customer satisfaction in the product markets could broadly serve as a suppressor to R&D, it can also serve as a driver for young and high-tech firms.
An Accurate and Rapid System to Identify Play Patterns in Tennis Using Video Recording Material: Break Point Situations as a Case Study
Authors: Prieto-Lage Iván , Prieto M.A. , Curran Thomas P. , Gutiérrez-Santiago Alfonso
Published: June 2018

The goal of this study was to present an accurate and rapid detection system to identify patterns in tennis, based on t-pattern analysis. As a case study, the break point situations in the final matches of the clay court tournaments played during the seasons 2011 and 2012 between the tennis players Novak Djokovic and Rafael Nadal were chosen. The results show that Nadal achieves a higher conversion rate with respect to Djokovic in the break point situations, independent of the outcome of the match. Some repetitive patterns of both players were revealed in break point circumstances. In long rally sequences (higher than seven hits), the Spanish player won more break points, both serving and receiving, as a result of unforced errors of his opponent’s backhand. In medium rally sequences (between four and seven hits), other factors such as the type, direction or serve location have shown to play an important role in the outcome of the point. The study also reveals that Djokovic frequently commits double faults in these critical situations of the match. This is the first time that t-patterns have been used to analyze the sport of tennis. The technique is based on computer vision algorithms and video recording material to detect particular relationships between events and helps to discover the hidden mechanistic sequences of tennis players.
Characterization and Catalytic Performance of Modified SBA-16 in Liquid Phase Reaction
Authors: Veli Simsek , Pinar Avci
Published: June 2018

A new mesoporous silica SBA-16 (called SP-16) was prepared by the direct hydrothermal method using Pluronic F127 (triblock copolymer; EO106PO70EO106) as surfactant and TEOS (tetraethyl orthosilicate) as silica source. The catalyst property of the SBA-16 was attained by loading the STA (Silicotungstic acid) active compound. The loading contents of STA were determined between 5 % and 40 % based on weight ratio of W and Si (W/Si). Catalytic activities and sustainability of SP-16 (10–20 %, W/Si) catalysts were determined by esterification (liquid phase reaction methanol and acetic acid) reactions at 343-353K, under autogenic pressure, 1/1–1/2 feed molar ratios (methanol/acetic acid) and in the presence of 0.4 g catalyst in the semi-batch reactor for 6 - 24h. Acetic acid conversion values of 10 and 20 % catalysts with 1/1 molar ratio at the end of 24h were obtained as 32–52.9 % and 47–60 %, respectively. On the other hand, when 1/2 molar ratio at 353K was used, 20 % catalyst showed 82.2 % conversion. Moreover, a second reaction experiment of 10 % catalyst was also carried out in identical conditions in the presence of catalyst recovered after the first methyl acetate reaction. The first and second reaction results of 10 % catalyst indicated that catalytic activity and sustainability were preserved for both 6 and 24h analyses. The physical properties of the materials obtained were investigated by Nitrogen sorption at 77K (BET), X-ray diffraction (XRD), Fourier transform infrared spectroscopy(FT-IR), Multiple Internal Reflection (DRIFT), Thermo-gravimetry/Differential thermal analysis(TG/DTA), Scanning electron microscope (SEM) and MAPPING analysis methods.
Determinants of Base-Pair Substitution Patterns Revealed by Whole-Genome Sequencing of DNA Mismatch Repair DefectiveEscherichia coli

Published: June 2018

Proofreading during DNA replication and post-replication mismatch repair are two major defenses against mutations. Foster et al. and Niccum et al. used mutation accumulation and whole genome sequencing to assemble a database of thousands...

Mismatch repair (MMR) is a major contributor to replication fidelity, but its impact varies with sequence context and the nature of the mismatch. Mutation accumulation experiments followed by whole-genome sequencing of MMR-defective Escherichia coli strains yielded ≈30,000 base-pair substitutions (BPSs), revealing mutational patterns across the entire chromosome. The BPS spectrum was dominated by A:T to G:C transitions, which occurred predominantly at the center base of 5′NAC3′+5′GTN3′ triplets. Surprisingly, growth on minimal medium or at low temperature attenuated these mutations. Mononucleotide runs were also hotspots for BPSs, and the rate at which these occurred increased with run length. Comparison with ≈2000 BPSs accumulated in MMR-proficient strains revealed that both kinds of hotspots appeared in the wild-type spectrum and so are likely to be sites of frequent replication errors. In MMR-defective strains transitions were strand biased, occurring twice as often when A and C rather than T and G were on the lagging-strand template. Loss of nucleotide diphosphate kinase increases the cellular concentration of dCTP, which resulted in increased rates of mutations due to misinsertion of C opposite A and T. In an mmr ndk double mutant strain, these mutations were more frequent when the template A and T were on the leading strand, suggesting that lagging-strand synthesis was more error-prone, or less well corrected by proofreading, than was leading strand synthesis.

Published: June 2018

La jirafa (Giraffa camelopardalis reticulata), es una especie de ungulado poligástrico, originario del continente africano cuyas poblaciones en cautiverio han aumentado de manera exponencial. Las enfermedades parasitarias se catalogan como una de las principales causas de mortalidad en esta especie.  El objetivo del presente trabajo fue determinar las especies y géneros de parásitos gastrointestinales (PGI) en jirafas de cautiverio en Guanacaste, Costa Rica. Se analizó en total 37 muestras de heces de 10 jirafas procedentes de un centro turístico. Las cuales se recolectaron de enero a mayo del 2017 en cuatro muestreos, excepto a una de ellas, nacida durante el estudio. El muestreo se realizó al momento de la defecación. Las heces fueron transportadas en frío a una temperatura de ≈4 oC, y remitidas al Laboratorio de Parasitología de la Escuela de Medicina Veterinaria de la Universidad Nacional. Las muestras fueron procesadas por técnicas coprológicas (Sheather, y sedimentación) para determinar la presencia de huevos de nematodos, trematodos y cestodos; inmunológicas (FasTest® Crypto-Giardia Strip), para detectar parásitos zoonóticos como Cryptosporidium parvum y Giardia duodenalis; McMaster para determinar la carga parasitaria (huevos por gramos de heces= HPG) del grupo Strongylida y el coprocultivo para determinar el porcentaje de larvas infectantes (L3). El 100 % de las jirafas analizadas fueron positivas a PGI, teniendo toda la población parásitos del grupo Strongylida. Las L3 identificadas correspondieron a 100 % Haemonchus spp., 10 % Cooperia spp. y 20 % Strongyloides papillosus.  No se encontraron PGI zoonóticos. El rango de HPG fluctuó de  < 50 a 625. El porcentaje de larvas infectantes del grupo Strongylida identificadas por coprocultivo fue 100 % (10/10) de Haemonchus spp. y 10 % (1/10) de Cooperia spp. Únicamente una jirafa tuvo infección mixta por Haemonchus y Cooperia. Este estudio representa el primer reporte de la presencia de PGI en jirafas de Costa Rica, y es el primero que identifica Cooperia spp. y Strongyloides papillosus en el nivel mundial.

[full article, abstract in English; abstract in Lithuanian]

If you own a book, it doesn’t mean at all that you have read it. Thus how the reading activity that took place in the past could be analysed and measured? And what methods could be used in case of extraordinary reading material, such as inscriptions on tombstones? In this article the author aims to show the possibility of investigating and measuring the process of reading inscriptions on tombstones in the past by applying Paul Connerton’s social theory on memory. Connerton’s model was tested on tombstones from Catholic cemeteries in Vilnius from the 19th century, the theoretical approach of applying this model is described in this article.
Unlocking US Teachers´ Vocal Potential by Raising Awareness About the Body-Mind Interconnectedness in Voicepilates Training
Authors: Vainio Katri-Liis
Published: June 2018

Teachers are at high risk of voice disorders, and voice trainings are shown to help to prevent the disorders. This qualitative phenomenological study investigated individual experiences of US teachers (n=5) attending “Teachers ́ voice with VoicePilates” interventions. Data was collected on participants ́ VHI (self-reported symptoms of vocal fatigue) and open-ended questionnaires, recordings of pre- and post-training vocal samples taken during the 4 days of the intervention session and 30 days after the interventions started. Interventions consisted of a voice hygiene lecture (30 min) and 2 x 45 minute and 2 x 2 hour group voice trainings. Participants ́ reflections were compared with the Finnish speech-language pathologists ́ expert group reviews, and they mainly correlated. All the respondents (n=5) felt that they had been paying close attention and have learnt something new about their voice and how to use it during teaching, describing concrete situations where new vocal and postural skills were consciously used. Results of the preliminary study give indications that teachers ́ awareness of their voice in teaching situations can be developed with VoicePilates method, thus improving teachers ́ vocal well-being. This study could offer voice teachers valuable insights in light of recent research in motor learning, hopefully leading to better practice regimens and more effective feedback, the two most important parameters in motor learning.
Caldas como Galileo: la cultura impresa de la República se inventa una monarquía oscurantista para legitimar su poder
Authors: Del Castillo Lina
Published: June 2018

Durante la década de 1820, el periódico oficial de la Gran Colombia editó selectivamente escritos de Francisco José de Caldas, exhibiéndolo como una figura galiléica —el martir de un régimen oscurantista—. La Gaceta se negó a reconocer el apoyo de la Monarquía española a Caldas y la extensa red que se dedicó a estudiar patrióticamente economía política e historia natural para la Corona. Los funcionarios colombianos hicieron uso de la cultura impresa para convencer a las audiencias nacionales de que la tiranía monárquica y el caótico federalismo habían sellado la suerte de Caldas. Lo hicieron para asegurar el estatus de Bogotá como capital y ratificar su autoridad centralizadora sobre otras ciudades que pudieran contestar estas pretensiones. Los oficiales colombianos reclamaban que Caldas había inspirado este llamado, suprimiendo con ello su apropiación de tradiciones de construcción estatal españolas de larga data. Las fuerzas que desarticulaban a Colombia en aquel entonces terminaron minando sus esfuerzos

MODELAGEM DA FERMENTAÇÃO ALCOÓLICA INDUSTRIAL CONTÍNUA COM MÚLTIPLOS REATORES EM SÉRIE
Authors: Zanardi Mayara Dos Santos , Da Costa Junior Esly Ferreira
Published: June 2018

A modelagem nos permite prever o comportamento do processo e, posteriormente, propor melhorias, com o objetivo de obter o máximo rendimento do produto. No Brasil, o etanol é obtido, principalmente, a partir da fermentação da sacarose, presente na cana-de-açúcar. A fermentação ocorre em bioreatores e pode ser conduzida de forma contínua. Esse trabalho tem por objetivo desenvolver e simular modelos matemáticos para um processo de fermentação real, contínuo e com cinco reatores em série. Os dados experimentais foram obtidos em uma usina autônoma, localizada no município de Linhares-ES. A empresa utiliza como matéria-prima o caldo cana-de-açúcar e a levedura Saccharomyces cerevisiae. Os modelos matemáticos foram obtidos a partir da equação do balanço de massa para cada componente de interesse no reator. A integração numérica do sistema de EDOs é realizada pelo método de Runge-Kutta de 4ª ordem. O problema de otimização não linear, utilizado para encontrar os valores dos parâmetros cinéticos, é resolvido utilizando o método de otimização Simplex Nelder-Mead, implementado no software Matlab®. A concentração dos componentes no reator não foi constante, mesmo se tratando de um processo contínuo, porque o mesmo não opera no estado estacionário. Os modelos que consideraram a inibição por produto apresentaram um melhor desempenho em representar o processo de fermentação quando comparados aos modelos sem inibição.

 

ABSTRACT

The modeling allows us to predict the behavior of the process and then to propose improvements, with objective to obtain the maximum yield of the product. In Brazil ethanol is mainly obtained from the fermentation of sucrose, present in the sugarcane. Fermentation occurs in bioreactors and can be conducted continuously. This work has the objective to develop and to simulate mathematical models for a real continuous fermentation process,  with five reactors in series. The experimental data were obtained in an autonomous plant, located in the Linhares-ES. The company uses as raw material sugarcane juice and Saccharomyces cerevisiae yeast. The mathematical models were obtained from the equation of mass balance for each component of interest in the reactor. The numerical integration of the ODE system is performed by the fourth-order Runge-Kutta method. The nonlinear optimization problem, used to find the kinetic parameter values, is solved using the Nelder-Mead Simplex optimization method implemented in Matlab® software. The concentration of the components in the reactor wasn’t constant, even if it is a continuous process, because it doesn’t operate at steady state. The models that considers the inhibition by product, presented a better performance, in representing the fermentation process, when compared with the models without inhibition.

Published: June 2018

Ésteres são compostos orgânicos também aplicáveis às indústrias químicas. Quando associados a uma base forte, como hidróxido de sódio (NaOH), os ésteres tendem a ser hidrolisados, produzindo sais orgânicos e álcool. Considerando aplicabilidades industriais, presente trabalho tem como objetivo estimar parâmetros cinéticos relacionados à reação de hidrólise alcalina dos ésteres acetato de etila, estearina e palmitato de isopropila. Observou-se que os parâmetros cinéticos estimados (Ea, ko, k, rA0) diferiram entre os compostos estudados. Para todos os tratamentos as concentrações de ésteres decresceram com o tempo, se tornando mais rápidas com aumento da temperatura, tendo como base o modelo de Arrhenius.

 

ABSTRACT

Esters are organic compounds also applicable to the chemical industries. When associated with a strong base, such as sodium hydroxide (NaOH), the esters tend to be hydrolysed, producing organic salts and alcohol. The present work considers the industrial applicability of esters while estimating kinetic parameters related to the alkaline hydrolysis reaction of ethyl acetate esters, stearin and isopropyl palmitate. It was observed that the estimated kinetic parameters (Ea, ko, k, rA0) differed between the compounds studied. For all treatments, the concentrations of esters decreased with time, becoming faster with increasing temperature, based on the Arrhenius model.

Published: June 2018

O presente ensaio apresenta as práticas diferenciadas de atividade física e os aspectos sócio-culturais da população japonesa e descendentes residentes no Brasil para tentar compreender o motivo da manutenção da sua tradição cultural até os dias atuais. Para isto recorremos à trajetória dos imigrantes japoneses para o Brasil, como são suas práticas culturais, sociais e esportivas, e se a cultura foi um grande aliado para sua efetivação na sociedade brasileira. Concluímos que historicamente, a população japonesa manteve sua tradição ao longo do tempo com vistas a retornar a sua terra natal e apresentar-se bem perante os japoneses que ali ficaram. Com o tempo, muitos não conseguiram retornar ao Japão, a tradição continuou sendo mantida e a cultura japonesa muito cultivada. E as práticas esportivas e ginásticas seguiram nesta mesma direção.

O objetivo deste estudo foi analisar os estados transitórios de humor de atletas de basquete participantes dos jogos do JIMI (Jogos do Interior de Minas). Para sua realização, foram selecionados 10 adultos da faixa etária entre 18 a 27 anos, do sexo masculino, participantes da fase classificatória do JIMI de basquete masculino que ocorreu no mês de junho deste ano. Para coleta dos dados, foi aplicado o questionário POMS (perfil dos estados de humor) que contem 65 itens que abordam o vigor como fator positivo de humor, e como fatores negativos, tensão, raiva, fadiga, depressão e confusão mental. Os dados do teste de POMS foram anotados em planilhas especificando os avaliados, jogo (primeiro e segundo) e momento (pré e pós) e foram calculadas as medias de cada estado em cada um dos momentos de cada jogo. Em seguida, foi feita a análise de variância e pós-teste de comparação. Como resultado, verificou-se que os atletas tiveram seus estados de humor (fadiga, raiva, depressão, vigor) muito altos durante os dois jogos, sendo que tensão e confusão mental não se alteraram. Porém, entende-se como necessário a realização de outros estudos sobre as emoções e sentimentos dos jogadores de basquete, para que de algum modo possamos auxiliar em futuros campeonatos.

Factors affecting service quality at Vietnamese retail banks
Authors: Phi Hoang Tran
Published: June 2018

Sustainable growth and development can be the most important lesson that banks have learned in recent decades. Banks would gain many benefits, win the competition and develop sustainably if there have been more and more loyal customers. Customer satisfaction will help build customer loyalty. In order to have loyal customers, service quality must be good. Quality customer service of the bank is to ensure customer satisfaction and take their needs into consideration to improve service quality. High customer service quality will generate value not only to meet customer needs but also the expectations of customers and make banks more prominent than their competitors. This study identifies factors that affect customer satisfaction with the service quality at Vietnamese retail banks. The results are obtained by qualitative and quantitative method. The research model with a questionnaire consisting of 22 variables, 5 scales for a survey of 554 customers, is identified and developed through interviews with experts and group discussions. The findings show that customer satisfaction with the service quality at retail banks is influenced by “reliability”, “responsiveness”, “empathy”, “security”, and “tangibles”. Based on the findings, solutions for improving service quality are proposed for Vietnamese retail banks.

Surgical treatment of atrial fibrillation (AF) in patients with valvular heart disease remains one of the most pressing problems in cardiac surgery. The purpose of the study was to determine the dynamics of proANP and myocardial damage markers depending on a modification of the radiofrequency (RF) Maze procedure used. The study involved 86 patients operated over a period from November 2007 to December 2010. A concomitant RF Maze procedure during mitral valve (MV) surgery was performed in two groups of the cohort; in group 1 it was the standard Maze IV scheme, in group 2 it was the modified one. In both groups we assessed the levels of proANP and myocardial damage markers. In group 1 a more significant decrease in proANP (by 4 times) was seen as compared to group 2 (by half). In group 1, the pleural effusion rate was 46.2%, and thoracocentesis rate reached 25.6%. In group 2, the corresponding rates were lower,14.9% and 27.7%. During the first postoperative day there was an increase in creatine phosphokinase MB fraction and Troponin T in both groups, and the rise was significantly higher in group 1. It should be noted that modified Maze IV RF ablation results in 80% freedom from AF, which is consistent with that of the standard Maze IV scheme. In patients with left atrial ablation the proANP secretion is less prominent early after surgery, and myocardial damage is lower in comparison with biatrial ablation.
La angustia de encontrarse con Dios.
Authors: Stuven María Teresa
Published: June 2018

The existential philosophy of Martin Heidegger by Edith Stein is a critique of Heidegger´s  Being and time. Stein summarizes the fundamental lines of Heidegger´s opus magnum and then criticizes it from phenomenology, Scholastics, and Christianism, the religion she converted to. Her critical standing focuses on the main concepts on which the work is based, such as the starting point of ontology, the being, Dasein, the condition of the thrown one, the fall, temporality, the One, death, and the denial of God’s existence. The purpose of this study is to examine the reasons that make impossible to affrm God’s existence in Heidegger´s Being and time.

This paper intends to relate the concept of Revelation – as understood by the Jewish –Christian tradition– and the refection on language, particularly from the theory of speech acts, emphasizing the performative and self-implicating dimension that, from that perspective, the language contains and projects to contribute to understand theological locutions better.
Juventude, religião e política: alguns apontamentos teóricos
Authors: Cardozo Carlos Eduardo
Published: June 2018

Nos estudos acerca da juventude e política encontramos posições que ora qualificam essa experiência como apática e desconectada da política, ora como essencialmente predisposta à política. Essas questões são formuladas ao longo do texto, a partir do que seria o cenário perceptível das relações entre religião e política.  No plano da cultura e do cotidiano, da esfera pública e da política, os atores religiosos se movimentam e trazem a público sua linguagem, ethos, demandas, nas mais diversas direções. O cenário atual suscita reposicionamentos temáticos e teóricos dos cientistas sociais, que são identificados e discutidos no texto.
A fé como expressão de compromisso com a vida, a justiça e a cidadania
Authors: Silva Drance Elias
Published: June 2018

A relação fé e política como expressão de compromisso na vida cristã há muito vem sendo debatido e com bastante entusiasmo, dentro e fora da Igreja. A experiência que se busca fazer de um Deus verdadeiro passa, necessariamente, pelo engajamento dos cristãos com a vida em solidariedade ao outro que sofre. O Deus de Jesus na sua história sempre teve como horizonte a libertação, sobretudo, dos pobres. O presente texto toma como referência esse mesmo horizonte, e afirma como fundamental, que a fé necessita de ações que resgate a dignidade do viver. A vida cotidiana de Jesus relatada por meio dos Evangelhos revela que, o grande pressuposto da mensagem cristã, é a pessoa humana. É Jesus mesmo quem diz e faz que isso seja percebido assim. A comunidade cristã como uma comunidade de sentido, sabe, que a luta pela justiça dá o tom e o conteúdo de nossas ações bem como não deixa vazia nossas orações.
Industrial Policies and Institutional Sustainability. the Case of Inner Areas in Italy
Authors: Musso Fabio , Esposito Gaetano Fausto
Published: June 2018

The principal aim of this study is to develop a model for analysing and assessing industrial policies based on the concept of institutional sustainability. Institutional sustainability should inform public policies in order to improve the productive structure of a country or a region, thereby contributing to its economic and social development. For this purpose, a two-step assessment model has been developed and tested on a case study. The case analysed is that of the inner areas in Italy, for which a development strategy has been planned at the national level. Results show an influence of the institutional system on market functioning and also the influence of a dominant culture in favor of institutional mechanisms, which are still affected by individualism and closure to collaborative market relationships. On the basis of this analysis, the main measures to be implemented in the case analysed have been identified.

One of essential phases in language learning is measurement. Test as a tool of measurement process must then be well constructed. The quality of test itself can be determined through test item analysis. However, in some occasions, teachers tend to ignore test item analysis because of time limitation and other responsibilities.  Referring to this problem, this research aimed to describe the quality of test items including the difficulty index, the discrimination index, the distractor index, and the reliability of the test and the Washback of teacher-made test on students’ motivation in learning English. It was conducted at Gamaliel Elementary School in academic year of 2016-2017. This case study utilized purposive sampling. In collecting the data, the researcher used interview, observation, and document analysis as the techniques of collecting data. The informants were an English teacher and students of Gamaliel Elementary School. The documents were students’ answer sheets. In analyzing test items, the researchers used ITEMAN program. The result of this study shows that the teacher-made test can be classified in good test. The test brings both positive and negative Washback in students’ motivation in learning. Therefore, it is recommended for the teacher to conduct test analysis as a way of evaluating and improving his teaching and learning and test itself as well as to encourage the students to study even though they are not confronted with a test.

Published: June 2018

OBJECTIVE

Catheter-associated cerebrospinal fluid (CSF) infection remains a serious event, especially for patients in neurocritical care units. The use of external ventricular drain (EVD) catheters impregnated with antimicrobial substances has led to a significant reduction of infection rates. This study was undertaken to compare the use of antimicrobial, silver-impregnated external lumbar drains (si-ELDs) and conventional ELDs.

METHODS

Patients with an indication for ELD placement were randomized to receive either a conventional or an si-ELD catheter. Regular assessment for CSF infections and device-related complications was performed. Neurosurgeons placing the ELD rated the usability and handling of the catheter on a 6-item ordinal performance scale (range: 1, very bad, to 5, very good). All microorganisms isolated in this study were tested for silver-susceptibility via a catheter-roll method.

RESULTS

A total of 48 patients were enrolled in the trial. The si-ELD catheters showed a nonsignificantly lower infection rate compared to conventional ones (4.2% vs 16.7%, p = 0.16). The majority of infections were caused by Staphylococcus species. Device-related complications occurred significantly less often with silver-impregnated-catheters than with conventional ones (8.3% vs 37.5%, p = 0.02). The usability was rated significantly better for si-ELDs (p = 0.003). Antimicrobial susceptibility was shown for si-ELDs against various Staphylococcus spp., but Candida parapsilosis and Escherichia coli were not affected by this antimicrobial agent.

CONCLUSIONS

Silver-impregnated ELD catheters, which could potentially reduce the number of CSF infections, show significantly better properties in regard to handling and fewer device-related complications. Whether they are superior to antibiotic-impregnated catheters or a clinical regimen involving antibiotic prophylaxis remains to be proven.

Acoustic Metamaterials in Aeronautics
Authors: Palma Giorgio , Mao Huina , Burghignoli Lorenzo , Göransson Peter , Iemma Umberto
Published: June 2018

Metamaterials, man-made composites that are scaled smaller than the wavelength, have demonstrated a huge potential for application in acoustics, allowing the production of sub-wavelength acoustic absorbers, acoustic invisibility, perfect acoustic mirrors and acoustic lenses for hyper focusing, and acoustic illusions and enabling new degrees of freedom in the control of the acoustic field. The zero, or even negative, refractive sound index of metamaterials offers possibilities for the control of acoustic patterns and sound at sub-wavelength scales. Despite the tremendous growth in research on acoustic metamaterials during the last decade, the potential of metamaterial-based technologies in aeronautics has still not been fully explored, and its utilization is still in its infancy. Thus, the principal concepts mentioned above could very well provide a means to develop devices that allow the mitigation of the impact of civil aviation noise on the community. This paper gives a review of the most relevant works on acoustic metamaterials, analyzing them for their potential applicability in aeronautics, and, in this process, identifying possible implementation areas and interesting metabehaviors. It also identifies some technical challenges and possible future directions for research with the goal of unveiling the potential of metamaterials technology in aeronautics.
Output Power Smoothing Control for a Wind Farm Based on the Allocation of Wind Turbines
Authors: Zhu Ying , Zang Haixiang , Cheng Lexiang , Gao Shengyu
Published: June 2018

This paper presents a new output power smoothing control strategy for a wind farm based on the allocation of wind turbines. The wind turbines in the wind farm are divided into control wind turbines (CWT) and power wind turbines (PWT), separately. The PWTs are expected to output as much power as possible and a maximum power point tracking (MPPT) control strategy combining the rotor inertia based power smoothing method is adopted. The CWTs are in charge of the output power smoothing for the whole wind farm by giving the calculated appropriate power. The battery energy storage system (BESS) with small capacity is installed to be the support and its charge and discharge times are greatly reduced comparing with the traditional ESSs based power smoothing strategies. The simulation model of the permanent magnet synchronous generators (PMSG) based wind farm by considering the wake effect is built in Matlab/Simulink to test the proposed power smoothing method. Three different working modes of the wind farm are given in the simulation and the simulation results verify the effectiveness of the proposed power smoothing control strategy.
A Novel Approach for Outdoor Fall Detection Using Multidimensional Features from A Single Camera

Published: June 2018

In the past few years, it has become increasingly important to automatically detect falls and provide feedback in emergency situations. To meet these demands, fall detection studies have been undertaken using various methods ranging from wearable devices to vision-based methods. However, each method has its own limitations and one common limitation that is prevalent in almost all fall detection studies is that they are restricted to indoor environments. Therefore, we focused on a more dynamic and complex outdoor environment. We used two-dimensional features and Rao-Blackwellized Particle Filtering for human detection and tracking, and extracted three-dimensional features from depth images estimated by the supervised learning method from single input images. As we used the methods in combination, we could distinguish a series of states in which a person falls more precisely and then successfully perform fall detection under dynamic and complex scenes. In this study, we solved the initialization problem, the main constraint of existing tracking studies, by applying the particle swarm optimization method to the human detection system. In addition, we avoided using the background reference image feature for image segmentation due to its vulnerability towards dynamic outdoor changes. The experimental results show a reliable and robust performance for the proposed method and suggest the possibility of effective application to the pre-existing surveillance systems.
A Lattice-Based Group Authentication Scheme
Authors: Huang Jheng-Jia , Tseng Yi-Fan , Yang Qi-Liang , Fan Chun-I
Published: June 2018

Authentication has been adopted in many areas, but most of these authentication schemes are built using traditional cryptographic primitives. It is widely believed that such primitives are not resistant to quantum algorithms. To deal with those quantum attacks, lattice-based cryptography was introduced by Ajtai in 1996. To the best of our knowledge, the existing lattice-based authentication schemes are based on a lattice-based public key encryption called NTRU: a ring-based public key cryptosystem, proposed by Hoffstein, Pipher, and Silverman in 1998. However, these schemes only support the case of a single user. In view of the aforementioned issue, we propose the first lattice-based group authentication scheme. The proposed scheme is secure against replay attacks and man-in-the-middle attacks. Moreover, compared with the existing lattice-based authentication schemes, ours provides the most efficient method to agree upon a session key among a group of users after mutual authentication.
PM1 Chemical Characterization during the ACU15 Campaign, South of Mexico City
Authors: Salcedo Dara , Alvarez-Ospina Harry , Peralta Oscar , Castro Telma
Published: June 2018

The “Aerosoles en Ciudad Universitaria 2015” (ACU15) campaign was an intensive experiment measuring chemical and optical properties of aerosols in the winter of 2015, from 19 January to 19 March on a site in the south of Mexico City. The mass concentration and chemical composition of the non-refractory submicron particulate matter (NR-PM1) was determined using an Aerodyne Aerosol Chemical Speciation Monitor (ACSM). The total NR-PM1 mass concentration measured was lower than reported in previous campaigns that took place north and east of the city. This difference might be explained by the natural variability of the atmospheric conditions, as well as the different sources impacting each site. However, the composition of the aerosol indicates that the aerosol is more aged (a larger fraction of the mass corresponds to sulfate and to low-volatility organic aerosol (LV-OOA)) in the south than the north and east areas; this is consistent with the location of the sources of PM and their precursors in the city, as well as the meteorological patterns usually observed in the metropolitan area.
Snow Level Characteristics and Impacts of a Spring Typhoon-Originating Atmospheric River in the Sierra Nevada, USA
Authors: Hatchett Benjamin J.
Published: June 2018

On 5–7 April 2018, a landfalling atmospheric river resulted in widespread heavy precipitation in the Sierra Nevada of California and Nevada. Observed snow levels during this event were among the highest snow levels recorded since observations began in 2002 and exceeded 2.75 km for 31 h in the northern Sierra Nevada and 3.75 km for 12 h in the southern Sierra Nevada. The anomalously high snow levels and over 80 mm of precipitation caused flooding, debris flows, and wet snow avalanches in the upper elevations of the Sierra Nevada. The origin of this atmospheric river was super typhoon Jelawat, whose moisture remnants were entrained and maintained by an extratropical cyclone in the northeast Pacific. This event was notable due to its April occurrence, as six other typhoon remnants that caused heavy precipitation with high snow levels (mean = 2.92 km) in the northern Sierra Nevada all occurred during October.
