Cognate Recognition and L 3 Vocabulary Acquisition Timea MOLNÁR

One of the new trends in applied linguistics is concerned with third or multilingual language acquisition. Several linguists suggest that prior language knowledge should be taken into consideration and relied on in third language (L3) vocabulary teaching. Starting from these suggestions, the present study aims to verify the positive effect of cognate recognition and cognate-based instruction in the process of third language acquisition. For this purpose, an English vocabulary test was carried out among Hungarian high school students with Romanian as a second language (L2) and learning English as an L3. Before the test, the study group was presented with the structural similarities between the L2 and L3 lexical items. The results show that the study group obtained slightly higher scores on the vocabulary test than the control group. Following instruction on cognate target words, the difference between the two groups became more accentuated. Furthermore, a positive correlation was found between the L2 proficiency and the L3 vocabulary test scores. The results of this study confirm the expectations that cognate-based instruction can positively influence third language acquisition for which a necessary prerequisite is a good command of the previously learnt languages.
Phenolic Fraction of Virgin Olive Oil : An Overview on Identified Compounds and Analytical Methods for their Determination

Among edible oils, virgin olive oil (VOO) has nutritional, technological and sensory characteristics that make it a unique and basic ingredient of the Mediterranean diet. These properties of VOO are attributed not only to the fatty acid composition (high level of oleic acid), which is not significantly different from refined olive oil (ROO), but especially to the high content of phenolic compounds, which are reduced by refining (bleaching and deodorization phases). Phenolic compounds, acting as natural antioxidants, increase the resistance of the oil to storage and heating. Moreover, phenols are the main contributors to the typical tastes of VOO (bitter and pungent attributes), and may also contribute to the prevention of several human diseases. Polar phenolic compounds belong to different chemical classes: phenolic acids, phenyl ethyl alcohols, flavonoids, lignans and secoiridoids. Approximately 50 compounds present in the phenolic fraction have been separated and identified to date, although researchers have not reached a consensus for the correct identification/denomination for many of these compounds. Due to variety of analytical approaches carried out on the complex phenolic pattern of VOO by high performance techniques, some disagreements have been emphasized. The aim of this review paper is to summarize and critically analyze the available information about phenolic compounds in VOO. _____________________________________________________________________________________________________________
Dose Physiologically Performing Vigorous Exercises Good for Body Over Time

The body physiological responses to the exercise paradigms rely on the exercise volume (or pace rate) and exercise duration. During exercise the glycolysis , fat metabolisms and oxygen consumption increase to meet exercise demands that is accompanied with enhanced cardiac and respiratory systems workouts . The body temperature is also dramatically will raise. Depending on the exercise intensity rates ,there are some physical stress on bones and musculature systems [1].
Low-luminosity X-ray sources and the Galactic ridge X-ray emission

Using the XMM-Newton Slew Survey, we construct a hard-band selected sample of low-luminosity Galactic X-ray sources. Two source populations are represented, namely coronally-active stars and binaries (ASBs) and cataclysmic variables (CVs), with X-ray luminosities collectively spanning the range 10 28−34 erg s −1 (2‐10 keV). We derive the 2‐10 keV X-ray luminosity function (XLF) and volume emissivity of each population. Scaled to the local stellar mass density, the latter is found to be 1.08 ± 0.16 × 10 28 erg s −1 M −1 ⊙ and 2.5±0.6×10 27 erg s −1 M −1 ⊙ , for the ASBs and CVs respectively, which in total is a factor 2 higher than previous estimates. We employ the new XLFs to predict the X-ray source counts on the Galactic plane at l = 28.5 ◦ and show that the result is consistent with current observational constraints. The X-ray emission of faint, unre solved ASBs and CVs can account for a substantial fraction of the Galactic ridge X-ray emiss ion (GRXE). We discuss a model in which � 80 per cent of the 6‐10 keV GRXE intensity is produced in this way, with the remainder attributable to X-ray scattering in the interste llar medium and/or young Galactic source populations. Much of the hard X-ray emission attributed to the ASBs is likely to be produced during flaring episodes.
Phase and group velocity matching for cumulative harmonic generation in Lamb waves

Owing to the enhanced sensitivity of nonlinear acoustic methods to material damage, the nonlinear Lamb wave propagation is pertinent to the nondestructive evaluation of platelike structures, and it is typically manifested as generation of higher harmonics. For dispersive waves such as Lamb waves, however, the cumulative growth of harmonics requires that the primary mode and the generated higher harmonic modes possess identical phase and group velocities. In this paper, this issue of the phase and group velocity matching in Lamb waves is explored based on a systematic analysis of the Rayleigh-Lamb frequency equations. The analysis shows that for certain values of the phase velocity, the Rayleigh-Lamb frequency equations are satisfied at equi-spaced frequencies which are multiples of the smallest. Such frequencies, together with the corresponding phase velocities and the Lamb modes, are determined analytically. Four such types of Lamb modes are identified: (i) Lame modes, (ii) symmetric modes with dominant longitudinal displacements, (iii) intersections of symmetric and antisymmetric modes and (iv) extra Rayleigh modes. For the first three types, it is also established that the primary and the harmonic modes have the same group velocity, and that the surface motion of the plate is featured with vanishing vertical or horizontal displacements. In contrast to these three types, the fourth type only exists for a special range of the transverse to longitudinal wave speeds of the solid. This type is not featured with a common group velocity, and neither of the vertical or horizontal displacement vanishes on the plate surfaces. The obtained results are summarized as tables, and demonstrated graphically on the dispersion curves for aluminum as well as iron plates.
A navigation method for multiple robots based on a single mobile node

To satisfy the requirements of independent navigation in low cost multiple robots, a navigation frame of masterslave robots with only one master robot is introduced briefly. A range-only navigation algorithm for slave robots of low cost is presented for the navigation in unknown current. This algorithm only needs a master robot. The master is just a single mobile node which has high navigation performance. Observability of this master-salve system is theoretically analyzed. The conditions of slave robot trajectory under which observability is guaranteed are evaluated by a slave robot in real-time. The slave takes appropriate action to control its heading to achieve observability if observability is lost on the current trajectory. The navigation algorithm is implemented by a standard extended Kalman filter, and it is able to acquire accurate estimation of robot's position. The simulation results show its effectiveness of the proposed algorithm.
Impact of continental outflow on chemistry of atmospheric aerosols over tropical Bay of Bengal

Abstract. The continental outflow from Indo-Gangetic Plain and south-east Asia dominates the widespread dispersal of pollutants over tropical Bay of Bengal (BoB) during the late NE-monsoon (January–March). It is thus pertinent to assess the impact on marine atmospheric boundary layer of BoB. The chemical data, based on analyses of size-segregated (PM2.5 and PM10) aerosols, suggest the dominance of nss-SO42− (range: 1.3 to 28 μg m−3) in PM2.5. Almost all SO42− is of anthropogenic origin and accounts for as much as 65 % of the water-soluble inorganic constituents. The impact of anthropogenic sources is further evident from the widespread depletion of chloride (range: 40 to 100 %) compared to sea-salt composition. The carbonaceous species (EC and OC) contribute nearly 25 % to PM2.5; and significant linear relationship with K+ suggests biomass burning as their dominant source (biofuels and agricultural waste). The enhancement in the fractional solubility of aerosol Fe, as assessed in PM2.5, re-emphasizes the impact of combustion sources (biomass and fossil-fuel) and chemical processing (of dust) during the long-range transport. The high enrichment factors of heavy metals (Pb and Cd) further demonstrate the influence of pollution sources on the chemistry of MABL. The downwind transport of pollutants and exchange across air-sea interface can, thus, have profound impact on the ocean surface biogeochemistry.
Analysis and Design of Tomlinson-Harashima Precoding for Multiuser MIMO Systems

The multiuser multiple-input-multiple-output (MIMO) downlink has attracted great research interests because of its potential of increasing the system capacity(Caire & Shamai, 2003; Vishwanath et al., 2003; Viswanath & Tse, 2003; Weingarten et al., 2006). Many transmitter precoding schemes have been reported in order to mitigate the cochannel interference (CCI) as well as exploiting the spatial multiplexing of the multiuser MIMO downlink. Tomlinson-Harashima precoding (THP) has become a promising scheme since the successive interference pre-cancelation structure makes THP outperform linear precoding schemes (Choi & Murch, 2004; Zhang et al., 2005) with only a small increase in complexity. Many THP schemes based on different criteria have been reported in the literature(Doostnejad et al., 2005; Joham et al., 2004; Mezghani et al., 2006; Schubert & Shi, 2005; Stankovic & Haardt, 2005; Windpassinger et al., 2004), in which one is the zero-forcing (ZF) criterion and the other is the minimum mean square error (MMSE) criterion. This chapter will consider the above two criteria based THP schemes’ analysis and design, respectively. For the ZF-THP scheme, initial research mainly focuses on the scenarios that each receiver is equipped with a single antenna (Windpassinger et al., 2004), where there exists only the transmit diversity, but without any receive diversity. Presently, the receive diversity due to multiple antennas at each receiver is taken into account (Stankovic & Haardt, 2005; Wang et al., 2006). In these literatures, it is commonly assumed that the total number of receive antennas is less than or equal to that of transmit antennas. Under this assumption, firstly the layers are divided into groups which correspond to different users, and then the dominant eigenmode transmission is performed for each group. Hereby, this kind of schemes is regarded as per-user processing. Actually, it is more common in the cellular multiuser downlink systems that the number of users is not less than that of transmit antennas at the base station (BS), which is investigated as the generalized case with THP in this chapter. In order to avoid complicated user selection and concentrate on the essential of transceiver filters design, our consideration is limited into a unique case that the number of users equals the number of transmit antennas, denoted as M. Besides, it is assumed that the channels of these M users have the same large-scale power attenuation.1 In this case a so-called per-layer processing can be applied by the regulation that each user be providedwith only one
FeatNet: Large-scale Fraud Device Detection by Network Representation Learning with Rich Features

Online fraud such as search engine poisoning, groups of fake accounts and opinion fraud is conducted by fraudsters controlling a large number of mobile devices. The key to detect such fraudulent activities is to identify devices controlled by fraudsters. Traditional approaches that fingerprint devices based on device metadata only consider single device information. However, these techniques do not utilize the relationship among different devices, which is crucial to detect fraudulent activities. In this paper, we propose an effective device fraud detection framework called FeatNet, which incorporates device features and device relationships in network representation learning. Specifically, we partition the device network into bipartite graphs and generate the neighborhoods of vertices by revised truncated random walk. Then, we generate the feature signature according to device features to learn the representation of devices. Finally, the embedding vectors of all bipartite graphs are used for fraud detection. We conduct experiments on a large-scale data set and the result shows that our approach can achieve better accuracy than existing algorithms and can be deployed in the real production environment with high performance.
Effect of High-Energy Diets on the Performance of Lactating Sows in Tropical Climate

Abstract Morales, J.J., Loeza, R. , Ángeles, Á. A. and Montiel, F. 2009. Effect of high-energy diets on the performance of lactating sows in tropical climate. J. Appl. Anim. Res., 36: 175–178. To study the effect of high-energy diets on performance of lactating sows in a tropical climate, 78 multiparous PIC sows on d 100 of gestation were divided into 4 groups (20x3, 18x1). From d 7 before parturition (d-7) until d 21 of lactation (weaning), sows were fed ad libitum diets containing 3.2, 3.3, 3.4 or 3.5 Meal ME/kg. At farrowing, BW was not different among diets (P>0.05), but at weaning it was lower for the control diet (P<0.05). BFT and BCS at farrowing and weaning and overall feed, energy and protein intake were lower for control group (P<0.05). Litter weight at birth was higher for the 3.5 Meal ME/kg diet (P<0.05) and at weaning it was lower for the control diet (P<0.05). Weaning-first service interval was longer in control group (P<0.05). In conclusion, increasing the dietary energy content by adding fat improved the overall performance of lactating sows in a tropical climate and prevented them from decreasing their voluntary feed intake.
The Factors Influencing Fans’ Attendance at Football Matches in the Kingdom of Saudi Arabia

This quantitative study investigates factors that affect fans’ attendance at football stadiums to watch Saudi Premier League (SPL) football matches. We adopted the comparative quantitative research method to compare the significance of the factors, which affect fans’ attendance at the football stadiums. Data was collected through a questionnaire. The research was carried out on a sample of 1,506 participants. The factors which have the most effect on fans’ attendance are the facilities and services offered by the stadiums and the fact that the seats are not numbered. However, in the case of SPL, external factors have the most impact on the fans’ lack of attendance at stadiums in the Kingdom of Saudi Arabia (KSA) including the fact that the matches are televised and the lack of commitment of fans to their favourite teams of SPL. This research also concludes that SPL organisers need to add glamour to SPL events by associating the branding of the league with overseas sporting brands, thereby attracting male fans to these events and improving fan attendance through the use of televised media and online and social media, which would help increase accessibility to fans.
Transmitter distribution for MIMO visible light communication systems

In the future, buildings will be lit using solid state lighting, particularly white light emitting diodes (LEDs). Solid state lighting is a rapidly expanding area of research due to the reliability of LEDs and the numerous applications possible including Visible Light Communications (VLC), where a white LED is used to illuminate a room at the same time as providing a data communications system. VLC systems are restricted by limited modulation bandwidths of typically only a few MHz. This can be overcome however, since multiple arrays of LEDs are manipulated, allowing a multiple-input multiple-output (MIMO) technique which simultaneously illuminates the room uniformly and provides parallel data transfer. In this paper, a non-imaging MIMO technique is employed, with results showing that the system does not perform consistently at all receiver positions, owing to symmetry. The simulations performed show that aggregate speeds up to 12Mbps can be achieved using this transmitter distribution.

Ultimately, it aims to set the trends of the upcoming projects and it discusses how image processing could contribute further to the study and the conservation of the cultural heritage.
DIELECTRIC STUDIES OF CORN SYRUP FOR APPLICATIONS IN MICROWAVE BREAST IMAGING

Permittivity and conductivity studies of corn syrup in various concentrations are performed using coaxial cavity perturbation technique over a frequency range of 250 MHz-3000 MHz. The results are utilized to estimate relaxation time and dipole moments of the samples. The stability of the material over the variations of time is studied. The measured specific absorption rate of the material complies with the microwave power absorption rate of biological tissues. This suggests the feasibility of using corn syrup as a suitable, cost effective coupling medium for microwave breast imaging. The material can also be used as an efficient breast phantom in microwave breast imaging studies.
Data Censoring with Set-Membership Affine Projection Algorithm

In this paper, the set-membership affine projection (SM-AP) algorithm is utilized to censor non-informative data in big data applications. To this end, the probability distribution of the additive noise signal and the excess of the mean-squared error (EMSE) in steady-state are employed in order to estimate the threshold parameter of the single threshold SM-AP (ST-SM-AP) algorithm aiming at attaining the desired update rate. Furthermore, by defining an acceptable range for the error signal, the double threshold SM-AP (DT-SM-AP) algorithm is proposed to detect very large errors due to the irrelevant data such as outliers. The DT-SM-AP algorithm can censor non-informative and irrelevant data in big data applications, and it can improve the misalignment and convergence rate of the learning process with high computational efficiency. The simulation and numerical results corroborate the superiority of the proposed algorithms over traditional algorithms.
Carbon Integration in Plantago Aristata (Plantaginaceae): The Reproductive Effects of Defoliation

Patterns of carbon integration in aclonal species are poorly understood in spite of their potential to influence individual fitness. To provide more information about these patterns, we performed a defoliation experiment with P. aristata. We examined, at the metameric level, the reproductive responses to the removal of the major carbon sources within metamers. Bracts on marked reproductive spikes and leaves subtending these spikes were removed at three stages of reproductive maturity: spike elongation, flowering, and fruiting. Spike dry weight and length, capsule number, seeds per capsule, and seed weight were measured. We tested the hypothesis that seed weight would respond least to defoliation. We also performed a complementary 14 C translocation experiment to measure the amount of radioactive carbon moving into the marked spikes from outside the metamer. Defoliation depressed all components of reproduction within marked spikes, and little 14 C was translocated from outside the metamer into the reproductive spikes, even those that were defoliated. Both results support the view that reproductive metamers in this species are largely autonomous with respect to their carbon budget. Defoliation during spike elongation most depressed reproduction, and bract removal depressed reproduction more than did leaf removal. The data suggest that bracts compensate for leaf removal by increasing their photosynthetic rate; however, the ability to compensate differs among plant populations. Of all the reproductive components, seed weight was least affected by defoliation. The data show, however, that the time of defoliation relative to reproductive development influences which reproductive components are affected.
Is the Polypill Empty? Chronicle of an Illusion

Atherosclerosis affects older adults from almost all over the world. It is characteristic of our socio-cultural education, largery due to changes in diet and physical activity over the past 200 years. Although in clinical practice risk factors are approached as problems that each patient has to face with their own personal effort –and in many cases they are considered secular sins (sedentarism, obesity, smoking)–, a broader view helps us understand that risk factors reflect a lifestyle that is typical of our culture. (1) Years ago, Geoffrey Rose developed a conceptual model which demonstrated that small quantitative changes in the whole population would have a great impact on global health. (2) For example: a mean systolic blood pressure reduction of 5 mm Hg in the population reduces the prevalence of high blood pressure values by 25%, and an average weight reduction of 1 kg (2.2 pounds) in the population also reduces the incidence of obesity by 25%. It is worth noting the contrast between the usual approach to medicine (to detect individuals with high risk factors –potentially ill– in order to correct them) and this proposal (society is ill). (3) The task is oriented towards changing population habits related to atherosclerosis; this change might have a major impact on risk reduction. “A large number of people at a small risk may give rise to more cases of disease than the small number who are at high risk. ” Behind this recognition, there were proposals from large-scale community interventions on correctable factors: increase number of hours of physical activity in schools, reduce the access to the so-called junk food, particularly for children, reduce the sodium content in diets with control of food production, eliminate dangerous lipids, replace animal fats with vegetables, etc. Yet, we know these changes are very difficult to implement. Campaigns aiming at individual changes on the basis of advertising and educational strategies have also failed to bring about the expected results. A recent review of The Cochrane Collaboration analyzed 55 published trials on population interventions with campaigns lasting 12 months on average (between 6 months and 12 years). It resulted in small reductions in risk factors,
