NEGATIVE-REFRACTIVE-INDEX TRANSMISSION-LINE METAMATERIALS AND ENABLING MICROWAVE DEVICES

Metamaterials are artificial periodic media with unusual electromagnetic properties. The size of their unit cells is much smaller than the incident electromagnetic wavelength, thus allowing the definition of effective material parameters such a permittivity ε, a permeability μ, and a refractive index n. In this paper, “left-handed” metamaterials are considered for which their permittivity and permeability are both negative. These metamaterials exhibit backward-wave propagation characteristics and therefore a negative index of refraction, as was predicted in the pioneering work of Victor Veselago [1]. Such “left-handed” or “Negative-Refractive-Index” (NRI) media were first implemented using bulk periodic arrays of thin wires to synthesize negative permittivity and split-ring resonators to synthesize a negative permeability [2]. A different approach for synthesizing 2-dimensional (2-D) NRI media in planar form was proposed in [3],[4]. The 2-D NRI structure presented in [3],[4] was realized by periodically loading a planar network of printed transmission lines (TL) with series capacitors and shunt inductors in a dual TL (high-pass) configuration, when compared to a conventional TL. The 2-D NRI medium was subsequently interfaced with a commensurate conventional dielectric, arguably leading to the first experimental demonstration of focusing from a NRI metamaterial [4], [5]. More recently, a 3-region lens arrangement was used to observe focusing beyond the diffraction limit [6]-[7] as was predicted by J.B. Pendry [8]. A similar TL approach was followed by Itoh and Caloz and led to interesting structures and useful circuits [9], [10]. Moreover, unique and intriguing anisotropic transmission-line metamaterials have been reported by Balmain in [11]. Some of the first FDTD simulations of NRI media have been reported in the pioneering work of R. Ziolkowski et al. in [12] and fascinating alternative focusing arrangements have been reported by Engheta et al. in [13].
In-Situ Communication and Labeling of Places

An increasing number of applications is based on the concept of personally meaningful places detected in individual trajectory data. This class of applications will only be accepted if the individual effort of labeling places is reduced to a minimum and the proposed place labels are meaningful. To allow for either the automatic generation of place concepts and corresponding labels, or the maintenance of a collaborative place database, we require better understanding of how people conceptualize their familiar environments in-situ, thus while being in the place. In this paper we present the results of an in-situ place labeling study. Our results suggest that the harmonization of diverse labels for personally meaningful places is possible and the operators for the automatic computation of place names are seizable.
Brittle Fracture Resistance Test on Composite Core of ACCC/TW

Brittle fracture tests were conducted on a pultruded hybrid composite rod (Drake size) consisting of carbon fibers and B-free E-glass fibers using a proprietary high glass transition temperature (Tg) epoxy resin system, in accordance with the procedure outlined in [1, 2]. The rod was subjected to a constant tensile load of 10,000 lbf (44.5 kN) while immersing a portion of the gauge section in a 1N and 5N nitric acid (HNO3) solutions. The applied load and acid immersion were continued for a period of 96 hours or longer. No failures occurred, and macroscopic inspection revealed no damage or change in the composite after this exposure. Subsequent to acid immersion, the tensile strength of the samples at room temperature was found to be considerably greater than the rated tensile strength of the core (34,410 lbf (153 kN)). The results indicate that the polymer composite used in the ACCC conductor is immune to brittle fracture under the conditions specified in industry-standard test protocols and under more aggressive acidic environments.
MINI-SUPERCELL EVENT OF 23 OCTOBER 2004 IN THE MEMPHIS COUNTY WARNING AREA

Low-topped supercell thunderstorms developed on 23 October 2004 and moved over portions of the Memphis County Warning Area (CWA)(west Tennessee and north Mississippi). These thunderstorms produced one tornado, several funnel clouds, and areas of severe straight-line wind damage. The most significant damage occurred when a tornado moved through the community of Marianna in Marshall County, Mississippi. The tornadic damage was rated F1 on the Fujita scale and produced a 70 m wide swath of damage along a 4.8 km long path (Fig. 1). One home in the region sustained significant roof damage (Fig. 2), two trailer homes were damaged, and many large trees were snapped and uprooted (Fig. 3). This tornado was spawned by one of the lowtopped supercell thunderstorms that developed.

China has become a considerable international tourist generating region for Cairns, Australia. Cairns, a world-known tourism destination in Queensland, is famous for the Great Barrier Reef and Daintree rainforest. Recently, Cairns has received significantly increasing number of tourists from China. With survey data collected in 2012, this study provides insights into the socio-demographic profile, travel characteristics and customer satisfaction of Chinese tourists visiting Cairns. The study is based on the expectancy-confirmation model by Oliver (1980) and examines Chinese tourists‟ expectations and perceptions. A questionnaire was developed to collect the data required for the study, and distributed to a convenience sample of Chinese tourists visiting Cairns between April and October 2012. The results show strong correlations between the Chinese tourists‟ expectations and perceptions. In turn, findings indicate that their expectation-confirmation significantly influenced their overall satisfaction. Also, results of the analysis showed moderate levels of overall satisfaction with the destination and a need to improve service standards of tourism related business in the Cairns area. This study enables tourism businesses in Cairns to learn about visitors from different culture background and so, develop strategies that meet their needs and enhance their travel experiences.

Technological Entrepreneurship as a Factor of Development and Restructuring of the Global Economy

The main problem dealt with in the publication is the role of technological entrepreneurship in stimulating the processes of development and restructuring of the global economy. The purpose of the paper is to identify and analyze the factors of development and restructuring of the global economy against the background of the challenges and circumstances arising out of compliance with the criteria of sustainable and inclusive development. The paper provides an overview based on the analysis of the world literature, including the Polish contribution, as well as on the experience gained thus far by the leaders in the civilizational transformations of the last decades. The processes illustrating the emergence of a new economic map of the world were based on information concerning the ranking of the technology readiness level — i.e., the capability of an economy to absorb technologies increasing productivity of production factors. This parameter is currently the key element of the economic competitiveness of the individual states. The sources of this information were global reports issued by the OECD, various UN agencies, the World Economic Forum, as well as independent international analytical institutions. The common access to products created as a result of applying disruptive technologies implies a large number of civilizational threats of a hitherto unknown scale. It is advisable to undertake formative actions addressed to users of new devices concerning responsible use of the achievements of inventors and manufacturers of new products.
Implementation of ISPWM based Cascaded Multilevel Converter for Voltage Enhancement and Harmonic Reduction

Multilevel inverter (MLI) is a new breed of power converter that is suited for high power applications. Multilevel inverter is an effective and practical solution for increasing power and reducing harmonics in ac waveforms. This paper focuses on the implementation of Inverted Sine Carrier Pulse-Width Modulation (ISCPWM) technique for asymmetric cascaded multilevel inverter with unequal DC sources. This technique combines the advantage of inverted sine PWM technique and asymmetric cascaded multilevel inverter with unequal DC sources. Performance evaluation of the proposed PWM strategy and inverter topology is done using MATLAB/SIMULINK for single phase and three phase asymmetric multilevel inverter. For a seven level output, the proposed inverter topology comprises of two H bridges and two DC sources which is of unequal in nature is simulated using MATLAB. With the implementation of ISCPWM technique there exists an enhancement in fundamental output voltage along with the reduction in Total Harmonic Distortion.

DYULGEROVA, B. , D. DIMOVA and D. VALCHEVA, 2016. Genetic diversity in six-rowed winter barley (Hordeum sativum jess., ssp. Vulgare L.) genotypes. Bulg. J. Agric. Sci., 22: 114–118 Twenty-five six-rowed winter barley genotypes were assessed for nature and magnitude of genetic diversity among them based of traits related to yield and quality of feed barley. The study was conducted in the Institute of Agriculture Karnobat, during the period 2010/2011-2011/2012. Maximum variation was found for grain weight per a spike and spike length. The results of the present study showed considerable genetic divergence among the genotypes. This suggested that adequate scope is available for selection of superior and diverse genotypes for use in a programmed aimed at enhancing grain yield potential and grain quality of winter feed barley. Considering diversity pattern and agronomic performance the cultivars Konrat, Fedor, Zimur and Dobrinya 3 and breeding lines K-3.11 and K-3.12 might be selected as promising genotypes for future hybridization program.
PATOGÉNICA Y GENÉTICA DEL AGENTE CAUSAL DE LA ANTRACNOSIS ( Colletotrichum gloeosporioides ) EN GUANÁBANA ( Annona muricata ) EN EL VALLE DEL CAUCA

La Antracnosis, causada por el hongo Colletotrichum gloeosporioides, ocasiona pérdidas hasta del 90% en huertos no tecnificados de guanábana. Para el control de la enfermedad se requiere conocer bien la sintomatología y las características del agente causal. Teniendo en cuenta que existe poca información al respecto, en este estudio se pretendió identificar y caracterizar morfológica, genética y patogénicamente los aislamientos de Colletotrichum spp. obtenidos de cultivos de guanábana en el Valle del Cauca (Colombia). De 109 aislamientos se caracterizaron 54, seleccionados al azar. La caracterización se basó en morfología de colonia, patogenicidad y reacción en cadena de la polimerasa (RCP) usando cebadores específicos ITS, CaInt2 (C. acutatum) y CgInt (C. gloeosporioides). Además se realizó corte con enzimas de restricción de la región ITS y se evaluó la diversidad genética de la población mediante Amplificación al Azar de Microsatélites (RAMs). Los resultados mostraron correlación de -0,84 entre características de crecimiento de los aislamientos con su patogenicidad, destacándose como muy patogénicos los de crecimiento lento que presentaron micelio gris, esporulación escasa y relieve ondulado. La amplificación con los cebadores específicos para C. gloeosporioides y C. acutatum, generó fragmentos de 450 pb y 490 pb respectivamente, corroborando la presencia de dos especies. Por otra parte la combinación de cebadores universales ITS1 e ITS4 generó un fragmento de 580 pb, que al digerirlo con las enzimas de restricción Hae III y RsaI, mostró diferencias en los patrones de restricción, dando lugar a dos grupos, correspondientes a las dos especies de Colletotrichum spp. El análisis de RAMs, mostró una gran variabilidad genética de los aislamientos y permitió concluir que hay correlación entre variabilidad patogénica diámetro de colonia, con variabilidad genética. Estos resultados evidencian la diversidad fenotípica y genética de Colletotrichum spp. asociado a la antracnosis en guanábana.

Neglect s childhood cruelty to animals a marker for physical altreatment in a prospective cohort study of children ?

Childhood cruelty to animals is thought to indicate that a child may have been maltreated. This study examined: (a) prevalence of cruelty to animals among 5to 12-year-old children; (b) the association between cruelty to animals, child physical maltreatment, and adult domestic violence; and (c) whether cruelty to animals is a marker of maltreatment taking into account age, persistence of cruelty, and socioeconomic disadvantage. Data were from the Environmental Risk (E-Risk) Longitudinal Twin Study, an epidemiological representative cohort of 2,232 children living in the United Kingdom. Mothers reported on cruelty to animals when children were 5, 7, 10, and 12 years, on child maltreatment up to age 12, and adult domestic violence. Nine percent of children were cruel to animals during the study and 2.6% persistently (≥2 time-points). Children cruel to animals were more likely to have been maltreated than other children (OR = 3.32) although the majority (56.4%) had not been maltreated. Animal cruelty was not associated with domestic violence when maltreatment was controlled for. In disadvantaged families, 6 in 10 children cruel to animals had been maltreated. In other families, the likelihood of maltreatment increased with age (from 3 in 10 5-year-olds to 4.5 in 10 12-year-olds) and persistence (4.5 in 10 of those persistently cruel). Although childhood cruelty to animals is associated with maltreatment, not every child showing cruelty had been maltreated. The usefulness of cruelty to animals as a marker for maltreatment increases with the child’s age, persistence of behavior, and poorer social background. © 2013 Elsevier Ltd. All rights reserved.

Comparison of the Frequency of Sleep Disorders among Patients with Rheumatoid Arthritis and Type 2 Diabetic Patients

Objective: The aim of this study was to compare the frequency of sleep disorder in rheumatoid arthritis (RA) patients and type 2 diabetic patients, and to find out the relationship between sleep disorder and DAS–28 (disease activity score). Method: The Pittsburg Sleep Quality Index (PCQI) and the Epworth Sleepiness Scale (ESS) were administered to patients with RA according and patients with type 2 diabetes mellitus. DAS-28 score was used to define the disease activity of RA. The results of RA patients were compared with the results of patients with diabetes mellitus (DM). Results: The participants of this study comprised 39 patients with RA (10 men and 29 women) and 40 patients with type 2 DM (12 men and 28 women). With regard to the categories in PCQI, there was no significant difference in poor sleep quality between the two groups. The rate of poor sleep quality was 87.2% in patients with RA and 79.5% in patients with DM (p=0.545). Furthermore, the Epworth Sleepiness Scale scores did not indicate any significant difference between the two groups with regard to excessive daytime sleepiness. We did not find any correlation of DAS scores with ESS and PSQI scores (respectively p=0.419, p=0.465). Conclusion: Sleep disorders are common in both type 2 diabetic and RA patients. Sleep disorder is a factor that affects the quality of life. The high rate of sleep disorder in both chronic diseases points to the importance of evaluating the possibility of sleep disorders in patients with RA and DM.
Detection of virulence genes in diarrhoeagenic E.coli isolated from different sources using Real Time PCR

The present study aimed to investigate the diarrheagenic E.coli from different sources and study their genetic relationship and diversity. Different types of samples (cattle fecal samples and internal organs; different types of plants; conduit; environmental samples; drinking water and soil samples (1105 samples) were collected). The isolated (if you identified them, then why you subject them further identification? )serotypes were subjected for detection of different virulence genes. The isolated strains (97.5%) were serogrouped to O26 (3.1%), O111 (3.4%), O101 (1.2%), O55 (1.5%), O148 (0.45%), O158 (0.63%), O78 (1.9%), O1 (0.63%), O2 (0.45%) O157:H7 (1.08%) and O157: H(1.62%) and 28 isolates of E.coli were untypable (2.5%) . E.coli O104:H4 2011 German strain was not detected in all DNAs extracted from all isolates. Bovine internal organs (liver; intestine and spleen) of cattle showed the highest rate of O157: Hisolation (2%). While the rate of O157: H7 isolation was similar in calves and cattle fecal samples (2%). Internal organs of poultry (liver, intestine and spleen) showed the presence of E.coli O157:H7 (2%). The clinical mastitic milk showed absence of E.coli O157:H7, but it was isolated from market milk. In minced meat the rate of O157:H7 was 4%. , sewage and conduit in rates of 3.6%, 10% and 3.3% respectively. Twenty six isolates express enterohemorrhagic virulence genes (stx1, stx2 and eae genes). The most predominant virulence gene detected was stx1 gene in combination with eae gene (9 isolates) followed by 6 isolates express stx2 alone, 6 isolates harbor both stx1 and stx2, 3 isolates express combination of stx1, stx2 and eae genes, only one isolate harbor eae gene alone. It was concluded, emphasizes the importance of safe water supply, good hygiene and sanitation practices in rural communities.
Jazz piano trio synthesizing system based on HMM and DNN

In this paper, we discuss a computational model of an automatic jazz session, which is a statistically trainable. Moreover, we describe a jazz piano trio synthesizing system that was developed to validate our model. Most previous mathematical models of jazz session systems require heuristic rules and human labeling of training data to estimate the musical intention of human players in order to generate accompaniment performances. In contrast, our goal is to statistically learn the relationship between a piano, a bass, and a drum player from performance MIDI data as well as information contained in lead sheets, for instance tonic key and chord progression. Our system can generate the performance data of bass and drums from only piano MIDI input, by learning the interrelationship of their performances and time series characteristics of the three involved instruments. The experimental results show that the proposed system can learn the relationship between the instruments and generate jazz piano trio MIDI output from only piano input.
Acoustic Emission Waveform Classification for Direct Wave Isolation using Convolutional Neural Networks

Acoustic emission (AE) signals are information-rich and can be used to estimate the location of damage in structures. However, many existing source localization algorithms may be deceived by indirectly propagated signals which are modulated by internal boundaries from complex geometry. We propose a method to filter out such signals so that simple localization methods may be used with complex structures. Our approach transforms AE time-series data into spectrograms and utilizes a convolutional neural network (CNN) to perform binary classification by leveraging spectro-temporal features. We achieve perfect classification accuracy on our dataset of artificially induced AE signals and show that the CNN is able to learn both general and context-specific features for the task at hand.
