Edge-Triggered Flip-Flop Circuit Based on Resonant-Tunneling Diodes and MOSFETs

This paper presents a novel circuit that combines resonant tunneling diodes with MOSFETs to create a very compact and high-speed flip-flop implementation. This edge-triggered flip-flop circuit offers smaller circuit size and area as compared to a true single-phase CMOS flipflop. The circuit can operate at lower supply voltage as compared to a conventional CMOS flip-flop and provides better noise immunity through isolation of dynamic storage nodes.
Ecological, morphological, and genetic differentiation of Daphnia (Hyalodaphnia) from the Finnish and Russian subarctic

We studied genetic differentiation of two subarctic Daphnia species (subgenus Hyalodaphnia; Cladocera: Anomopoda) in relation to ecological and morphological diversification. Daphnia longispina and the recently discovered species Daphnia umbra are genetically differentiated based on mitochondrial 12S rDNA and internal transcribed spacer (ITS) regions. Genetic differentiation of 12S rDNA among the two sister taxa is in the range of differentiation among other Hyalodaphnia species (uncorrected genetic distance = 0.11). Despite frequent interspecific hybridization among Daphnia (Hyalodaphnia) species, we found no interspecific hybrids of D. umbra and D. longispina. D. umbra is for the first time recorded to occur in Northern Finland and Russia (Pechora Delta), and to cooccur in neighboring sympatry with Daphnia longispina across a subarctic region in northern Finland. Species are ecologically differentiated: D. umbra occurred at higher elevations, in larger and deeper water bodies than D. longispina. Species did not differ significantly in levels of ultraviolet‐protective melanin pigmentation but varied with regard to environmental preferences, such as fish predation and levels of total dissolved organic carbon (DOC). These findings argue that ecological differentiation and divergent selection might have caused speciation or at least are responsible for the maintenance of reproductive isolation among subarctic Daphnia (Hyalodaphnia) species.
Identification of the Swiss Z24 Highway Bridge by Frequency Domain Decomposition

This paper presents the result of the modal identification of the Swiss highway bridge Z24. A series of 15 progressive damage tests were performed on the bridge before it was demolished in autumn 1998, and the ambient response of the bridge was recorded for each damage case. In this paper the modal properties are identified from the ambient responses by frequency domain decomposition. 6 modes were identified for all 15 damage cases. The identification was carried out for the full 3D data case i.e. including all measurements, a total of 291 channels, a reduced data case in 2D including 153 channels, and finally, a 1D case including 20 channels. The modal properties for the different damage cases are compared with the modal properties of the undamaged bridge. Deviations for frequencies, damping ratios and MAC values are used as monitoring variables. From these results it can be concluded, that frequencies and model shapes for the structure changed significantly during damage. Further, it can be concluded, that the spatial information gained by a large number of channels does not seem to result in significant better estimates of frequency and mode shape deviations.
Closed-Loop Design for Standalone Photovoltaic-Battery Hybrid Power System

The photovoltaic-battery hybrid power system is constructed with photovoltaic panels and a battery, which are connected to the load via a boost converter and a bidirectional buck/boost converter, respectively. Depending on the amount of available solar power, the photovoltaic panels may operate in a maximum power point tracking (MPPT) mode or off-MPPT mode to regulate the output voltage, and at the same time, the battery may provide power to the load or store energy from the solar power. The whole system is thus designed to operate with multiple operating modes. Compared to the system of single operating mode, the stability analysis and closed-loop design is much more difficult, as the control loops are usually coupled with each other and the design for stable operation of such system requires consideration of the stability conditions for all possible operating modes. To design the closed-loop, the commonly used small-signal analysis method based on averaged state-space is helpless here, and then the nonlinear analysis method with discrete-time mapping model is performed to evaluate the stability boundaries of the system. The parameters of the closed-loop are chosen in the stable region of the stability boundary diagrams. Moreover, a prototype is built and the experimental results are shown to verify the nonlinear analysis method in the design of closed-loop.
The Influence of Pop-up Advertising on Consumer Purchasing Behavior

Social media platforms such as Facebook, Twitter, MySpace, Linkedln, and Youtube have attracted substantial number of users, many of whom spend several hours daily on these platforms. These platforms have therefore become fertile grounds for marketers/advertisers to target different types of customers. However, the impact of these ads has become more and more pervasive. The study therefore explores the influence of online advertising, especially popup ads on the purchase behavior of social media users. A sample of social media users who are familiar with these online ads were drawn from a public university in Ghana. The findings reveal that social media users perceive online ads, especially pop-up ads as intrusive and ineffective. Also the study establishes that pop-up ads have little impact on the purchase behavior of social media users since a negative attitude has been formed towards pop-up ads. Based on the findings of the study, it is recommended, among other things, that advertisers should design pop-up ads that are user friendly and less intrusive. Keywords-online advertising; social media; pop-up ads; purchasing behavior; Ghana
Antihyperglycemic and antioxidant activity of Viscum album extract

The antihyperglycemic and antioxidant effects of water extract of local Viscum album in alloxanized-rats were investigated. This study performed during 2009 in Babol University of medical sciences (Mazandaran Province, Iran). V. album leaves growing on oaks collected and extracted with hot water. The 90 animals that were used in this investigation were male Wistar rats. 60 rats were gavaged with 500 and 1000 mg/kg/day of V. album extract. One hour after final feeding, freshly prepared alloxan injected subcutaneously. Then blood glucose level was measured according to glucose oxidase method. The antioxidant activity of serum was determined by FRAP assay and serum insulin level was measured with ELISA. The administration of V. album extract (500 and 1000 mg/kg/day) significantly reduced the increase in serum glucose concentration in alloxan-hyperglycemic rats. Both the extracts from V. albumenhance the serum insulin level as compared to control rats. Serum antioxidant activity in low dose of extract was significantly higher at 48 and 72 h after alloxan injection. Serum antioxidant activity in the high dose was significantly higher at 24, 48 and 72 h. This study demonstrated that V. album extract reduced the blood glucose and increases the antioxidant power of alloxanized-rats. Much more work is clearly needed before phytotherapy for diabetes can be advanced to the clinic. Key words: Viscum album, antihyperglycemic, antioxidant, alloxan.
Genetic Diversity Assessment and Phylogenetic Analysis of Peanut (Arachis hypogaea L.) in RDA Genebank Collection using SSRs

It is very crucial to evaluate the genetic diversity of peanut genetic resources for identification of peanut germplasm accessions and variety improvement. Cultivated peanut generally has two subspecies, hypogaea and fastigiata. In this study, we identified peanut into three plant types, virginia (var. hypogaea), spanish (var. vulgaris), and valencia (var. fastigiata). Former one belongs to ssp. hypogaea and latter two are involved in ssp. fastigiata. Twenty SSR markers were used to assess the genetic variation of three sets, hypogaea, vulgaris, and fastigiata, respectively. Out of variety-specific SSR primers tried in this study, ten pairs of SSR primers showed polymorphisms. Each accession could be identified by a specific set of polymorphic SSR primers, and allele number was evaluated among accessions, with an average of 6.7 in var. hypogaea and 5.4 in var. vulgaris and fastigiata. For evaluation of genetic diversity, gene diversity ranged from 0.336 to 0.844 and PIC (polymorphism information contents) ranged from 0.324 to 0.827 were investigated. Dendrograms based on genetic distances were constructed, which showed the existence of three different clusters. And these three different clusters might be associated with the genes involved in three plant types. The results also suggested that there were plentiful SSR polymorphisms among peanut germplasm accessions in RDA (Rural Development Administration, Korea) Genebank and SSRs might play an important role in evaluating peanut accessions and cultivar improvement.
Comparison of dynamic responses for IPM and SPM motors by considering mechanical and magnetic coupling

The permanent magnet motor is often the most important element in high performance rotor applications and also a frequent source of vibration and acoustic noise. Because of manufacturing imprecision such as mass unbalance, shaft bow and bearing tolerances, rotor eccentricity extensively exists in all kinds of electric machines. This paper investigates magnetic unbalanced forces for IPM and SPM motors which are widely used in a washing machine due to high average torque and dynamic responses of a rotor motor system when rotor eccentricity exists. For the magnetic field analysis, a finite element method is used to account for the magnetic saturation and rotor eccentricity. An IPM motor, mostly chosen to realize high speed operation, shows a worse effect on magnetic unbalanced forces and dynamic responses compared with SPM motor due to magnetic saturation when the eccentricity exists.
Transovarial Transmission and Dengue Virus Serotypes in Aedes Aegypti In Kupang

Dengue is an endemic disease in almost all provinces in Indonesia, including NTT pro-vince and Kupang City. DHF prevention and control efforts need to be accompanied by understanding of the epidemiological and entomological aspects. This study proves the presence of transovarial transmission and serotypes of Dengue virus in Ae. aegypti in areas with different endemics in Kupang City. The study was conducted in endemic, sporadic and Dengue-free villages. Samples from each location were 30 head squash Ae. aegypti females for examination of Dengue virus by IHC methods and 10 Ae. aegypti females for serotypes check of Dengue virus with RTPCR. Data presented in tables and images then analyzed descriptively. This study finds that transovarial infection rates 9.2% with serotype Dengue virus-1. As many 97.5% of respondents have heard about Dengue by most cadres resources (24.5%) and health workers (24%). Transovarial infection is found in endemic, sporadic and free areas so that the Dengue vector control needs to be done in the three regions with different endemicity.
Nutrient regeneration and oxygen consumption by sediments along an estuarine salinity gradient

Nutrient fluxes and oxygen consumption (SOD) across the sediment-water interface were measured in situ along with vertical profiles of dissolved and particulate-phase nutrients in sediments and overlying water at 8 locations along the salinity gradient of Chesapeake Bay during spring and summer. Strong spatial and temporal patterns were evident. Highest rates of sediment NH: regeneration and SOD occurred in summer at mid-salinity (12 to 17 %a) stations. Sediment fluxes of dissolved inorganic phosphorous (DIP) were always low, possibly due to relatively oxidized conditions in surficial sediments. Nitrate (NO;) fluxes generally were directed into the sedirnents in spring and from the sediments during summer, and in both seasons fluxes were proportional to NO3 concentrations in overlying waters. Seasonal shifts in sediment 0:N flux ratios suggest that denitrification may have been important in spring but not summer. Significant relations were inferred between C:N:P composition of suspended materials and surficial sediments and the magnitude and direction of sediment-water fluxes. Although accretion of particulate nitrogen in sediments was less than 6 % of NH: regeneration in the lower bay, it was similar to rates of NH: flux in the low salinity region, suggesting that burial represents a significant sink for N in some estuarine zones. SOD constituted an important term in water column O2 budgets at all stations (1G50 % of total respiration), and sediment regeneration of NH: was capable of supplying 13 to 40 % of calculated phytoplankton N requirement, being more important during the summer period of higher productivity.
Minimal Partitions for p-norms of Eigenvalues

In this article we are interested in studying partitions of the square, the disk and the equilateral triangle which minimize a p-norm of eigenvalues of the Dirichlet-Laplace operator. The extremal case of the infinity norm, where we minimize the largest fundamental eigenvalue of each cell, is one of our main interests. We propose three numerical algorithms which approximate the optimal configurations and we obtain tight upper bounds for the energy, which are better than the ones given by theoretical results. A thorough comparison of the results obtained by the three methods is given. We also investigate the behavior of the minimal partitions with respect to p. This allows us to see when partitions minimizing the 1-norm and the infinity-norm are different.

T. : +90 3862805322 F. : +90 3862805326 E-Mail: gokce_4068@hotmail.com Abstract Aim:The aim of the present study is to evaluate sleep quality in the elderly living in Kırşehir city center and to identify related factors. Material and Method: Subjects of this descriptive study included elderly individuals registered in family health centers in Kırşehir city center. The sample included 700 elderly individuals selected using stratified sampling method. Data were collected via face-to-face interviews conducted on December 3%u201331, 2016, using a questionnaire on sociodemographic characteristics, Pittsburgh Sleep Quality Index, and UCLA Loneliness Scale. Ethics committee approval and informed consent of patients were obtained. Numbers, percentages and mean values, as well as logistic regression (enter method) were used in statistical analysis. Results:The mean sleep quality score was 7.63 ± 3.23, and 70.4% of them had poor sleep quality. According to the logistic regression analysis, risk factors that had a negative effect on sleep quality were female sex, low educational level, being single/divorced, having no children, negative perception of economic status, presence of a chronic disease, regular medication use, daytime sleepiness, and feelings of loneliness. Discussion: According to the findings of the study, elderly individuals had poor sleep quality, and several factors such as demographic and socioeconomic factors had a negative effect on sleep quality. According to the results of the present study, we suggest conducting community-based studies to evaluate risk factors that have a negative effect on sleep quality in elderly individuals, while considering psychological and social care, support, and care and management of chronic illnesses.
Osteology of the African annual killifish genus Callopanchax (Teleostei: Cyprinodontiformes: Nothobranchiidae) and phylogenetic implications

Osteological structures of Callopanchax are fi rst described and illustrated. Twenty-six characters derived from comparisons of osseous structures among some aplocheiloid fishes provided evidence supporting hypotheses of relationships among three western African genera (Callopanchax, Scriptaphyosemion and Archiaphyosemion), as proposed in recent molecular analysis. The clade comprising Callopanchax, Scriptaphyosemion and Archiaphyosemion is supported by a laterally displaced antero-proximal process of the fourth ceratobranchial. The sister group relationship between Callopanchax and Scriptaphyosemion is supported by a constriction on the posterior portion of the parasphenoid, an anterior expansion of the hyomandibula, a rectangular basihyal cartilage, an anterior pointed process on the fi rst vertebra, and a long ventrally directed hemal prezygapophysis on the preural centrum 2. Monophyly of Callopanchax is supported by a convexity on the dorsal margin of the opercle, a long interarcual cartilage, and long neural prezygapophyses on the anterior caudal vertebrae.
Effects of Hyper-Pronunciation Training Method on Japanese University StudentsPronunciation

Mutual intelligibility or overall comprehensibility of L2 speech has been regarded as a crucial goal in recent ESL pronunciation pedagogy. In other words, native-like accuracy has received less pedagogical attention . It is not necessarily reasonable, however, to underestimate native -like accuracy in pronunciation teaching targeting student -teachers in ESL/EFL teacher education settings. This study, therefore, examined the efficacy of Hyper
CHANGE AND FIRM VALUATION IN U.S. FOOD RETAILING AND MANUFACTURING

The competitive environment in the agri-food sector is evolving as the food manufacturing and retailing industries become more concentrated. Evolving industry structure and new firm investment portend changes in future firm competitiveness and performance. This research describes how large food-manufacturing and retail firm performance has shifted and how firm valuation signals expected future change in performance. While there have been expectations that return on investment of large food retailers would increase relative to large packaged-food manufacturers, we find that this has not yet happened and that market valuations imply that retailers are not likely to gain on manufacturers in the future.
Runoff estimation from a hilly watershed using geomorphologic instantaneous unit hydrograph.

Estimation of direct runoff using Geomorphologic Instantaneous Unit Hydrograph (GIUH) for a fourth-order hilly watershed in Uttarakhand (India) is presented in this study. The kinematic-wave theory was used to analytically and probabilistically determine the travel times for overland-flow and stream-flow in Horton-Strahler stream-ordering system of the watershed using topographic parameters alone (GIUH-I), and in terms of stream-order-law ratios (GIUH-II). The time to peak runoff for the predicted hydrograph was occurring about one half-hour prior (25% error) to that of the observed one for the given data set; however, the hydrograph shapes were comparable. The coefficient of efficiency for models was lower probably due to the shift in the predicted time to peak runoff, while the errors in magnitude of peak runoff and volume were within the acceptable limits. The GIUH-I model gave better prediction of peak and runoff volume. However, on the basis of coefficient of efficiency alone, the GIUH-II was found to be better than GIUH-I. Because these models utilize only topographic and geomorphologic parameters of the watershed and the only measurable field data is the width of
Spectroscopic variability and magnetic fields of HgMn stars

The discovery of exotic abundances, chemical inhomogeneities, and weak magnetic fields on the surface of late B-type primaries in spectroscopic binaries has important implications not only for our understanding of the formation mechanisms of stars with Hg and Mn peculiarities themselves, but also for the general understanding of B-type star formation in binary systems. The origin of the abundance anomalies observed in late B-type stars with HgMn peculiarity is still poorly understood. The connection between HgMn peculiarity and membership in binary and multiple systems is supported by our observations during the last decade. The important result achieved in our studies of a large sample of HgMn stars is the finding that most HgMn stars exhibit spectral variability of various chemical elements, proving that the presence of an inhomogeneous distribution on the surface of these stars is a rather common characteristic and not a rare phenomenon. Further, in the studied systems, we found that all components are chemically peculiar with different abundance patterns. Generally, He and Si variable Bp stars possess large-scale organised magnetic fields that in many cases appear to occur essentially in the form of a single large dipole located close to the centre of the star. The presence of magnetic fields in the atmospheres of HgMn stars has been demonstrated in several studies. In addition to the measurements of longitudinal and quadratic magnetic fields, this work also showed evidence for a relative magnetic intensification of Fe II lines produced by different magnetic desaturations induced by different Zeeman-split components.

A Survey on Classification of ECG Signal Study

Electrocardiogram (ECG) is a non-linear dynamic signal which plays the main role in diagnosis heart diseases. Classification of ECG signal is one of the most important reason of diagnosing the heart diseases. Detecting accurate ECG signal not only the most difficult task but also classifying heart signal is very difficult task. There are many types of classifiers are available for ECG classification. The most popular classifier that used in ECG classification is Artificial Neural Network (ANN) and in second degree is Support Vector Machine (SVM). In this paper, we discuss a survey of preprocessing, ECG database, feature extraction and classifiers. This paper also discusses background of Electrocardiogram, evaluation matrices of classifiers and issues of classifiers.
