Temperature induced single domain-vortex state transition in sub-100 nm Fe nanodots

Magnetization reversal in nanomagnets via a vortex state, although often investigated at the remanent state, may not necessarily display a zero remanence or a highly pinched hysteresis loop. In contrast, the irreversible nucleation/annihilation events are clear indications of a vortex state. In this work, temperature induced single domain–vortex state transition has been investigated in 67nm Fe nanodots using a first-order reversal curve (FORC) technique. The two phase coexistence is manifested as different features in the FORC distribution. At lower temperatures, it becomes harder to nucleate and annihilate vortices and the amount of single domain dots increases.
BLOG EDGE DETECTION METHOD FOR CAROTID ARTERY ULTRASOUND IMAGE

Nowadays, ultrasound image is important and very useful in medical field. It is a technique used for visualizing body structures including tendons, muscles, joints, vessels and internal organs. For the atherosclerosis diagnosis, ultrasound imaging is commonly used because of the noninvasively assessment in monitoring condition inside the carotid artery. In certain conditions, the acquired images may be unclear caused by speckle noise and other factors. Thus, may affect the accuracy of artery wall detection. This study proposes an edge detection method that could detect edges in carotid artery images accurately without including noise or fine details by using the combination of the Bilateral Filter, Otsu Threshold and Gabor Filter. The Bilateral Filter is used to suppress the noise level in the input image. Otsu Threshold used to segment the regions into background and objects. The Gabor Filter is applied to detect edge accurately without including noise or fine details. From our simulation, the proposed method is capable of producing sharp edgemap image with less noise and detect edges accurately in comparison to conventional edge detection methods for different carotid artery ultrasound images.
Design of a Multimode MIMO Antenna Using the Theory of Characteristic Modes

In this communication, the design procedure of a multimode Multiple-Input Multiple-Output (MIMO) antenna is presented. The antenna consists of a metallic ring antenna operating with different orthogonal modes, whose performance in a MIMO system is similar to traditional antenna arrays. Thus, a compact MIMO antenna is obtained, which is very suitable for mobile terminals. A modal analysis of the antenna is carried out first by means of the Theory of Characteristic Modes, in order to identify the different radiating modes of the antenna. Then a set of feeding configurations is proposed so as to excite these modes. As the modes must operate in the same frequency band, a loading technique is used in the antenna in order to shift the resonance frequency of the modes to the proper band.
A general approach for international genetic evaluations robust to inconsistencies of genetic trends in national evaluations

This paper is a contribution from the PROTEJE project. It presents an approach which makes uses in a sire model of annual information (= average daughter yield deviations per year of performance and lactation number) for each sire. It is shown that with a suitable sire model (including a year x country effect, a lactation x country effect and a within country regression on age of the sire when his daughters are born), the genetic parameters and the sire solutions obtained are robust to overor under-estimation of genetic trend in the national models. The approach has other benefits: validation of genetic trends is no longer critical (although obviously desirable), deregression becomes obsolete. An extension to categorical or survival traits is briefly described and a general strategy for the computation of equivalent daughter contributions and daughter yield deviations and their validation is proposed.
Effect of 6-benzylaminopurine ( BAP ) in different basal media on shoot multiplication of Aquilaria hirta and detection of essential oils in the in vitro shoots

Aquilaria hirta, locally known as ‘chandan’ or ‘chandan bulu’, is used interchangeably with Aquilaria malaccensis (karas) to produce gaharu. With the decline in the A. malaccensis populations, harvesting of this precious wood has begun to extend to A. hirta. There is also an increasing interest to plant karas trees and related species. Therefore, a rapid propagation method is necessary to meet the increasing demand for planting materials as well as for conservation purposes. In this paper, we reported on the effect of 6-benzylaminopurine (BAP) in different basal media, Murashige and Skoog (MS) (1962) and woody plant medium (WPM) on shoot multiplications of A. hirta using nodal segments from young seedlings of A. hirta as explants and the chemical analyses of essential oils present in the in vitro shoots. The MS medium supplemented with 0.1 mg/l BAP was the most effective for multiple shoot formation in A. hirta, producing an average of 6.1 shoots per culture, which is significantly higher than other treatments. New shoots produced attained a length of 0.4 to 1.8 cm within 25 days in both MS and WPM basal media. The highest length of new shoots was obtained in WPM containing 0.1 mg/l BAP. Analysis of the oils by gas chromatography (GC) and gas chromatography-mass spectrometry (GCMS) revealed the presence of β-caryophyllene in trace amounts. Other compounds detected were tetradecanal, hexadecanoic acid, methyl linoleate, linoleic acid, isophytol and phytol acetate.
Is the Tokyo Foreign Exchange Market Efficient from Two Perspectives of Forward Bias and Anomaly

This paper examines the efficiency of the Tokyo Foreign Exchange Market from two perspectives. One is whether or not forward bias in this market has existed and the other is the effect of interventions in the market with a focus on whether or not a day-of-the-week anomaly exists in it. Empirical results show that forward exchange rates are a biased predictor of future spot exchange rates; however, there are some anomalies in the market. The findings suggest the conclusion that this market has not been completely efficient.
Metabolic state alteration of neural stem cells controls FAS-mediated apoptosis and neurogenesis

Metabolic stress causes an increased Fas-FasL (receptor-ligand pair) expression in Neural Stem Cells (NSCs) leading to Fas-induced apoptosis. In this study, we discuss the exposure of NSCs to different metabolic treatments that provoke cellular stress responses. We demonstrate that challenging cultured NSCs to ethanol (ETOH) increased cellular death via Fas-mediated apoptosis. Moreover, we establish that NSCs cultured under low lipid conditions, in which they were deprived of essential fatty acids, demonstrated increased cellular survival rates suggesting an increased ability for these lipid-starved cells to endure a stressed environment. This was further confirmed by exposing NSCs to low glucose levels and observing a decrease in percent death in low lipid NSCs. When stressed, NSCs have increased reactive oxygen levels and are susceptible to apoptosis. These findings indicate that under starved and stressed conditions, and in the presence of Fas Ligand (FasL), NSCs pursue fatty acid oxidation by burning fat as fuel. This may be the key to better understand the metabolic states of brain tumors and the characteristics of cancer.
Sri Lankan Consumer Attitudes towards Healthy Meals

As a result of changes in every aspect of human life, the consumption pattern of people getting changed drastically. Busy schedule of women increase the consumption of ready-made foods. However, the unhealthy nature of these products create serious health issues to the society. Sri Lankan people are very well aware of the bad results of these foods. Still vendors offering those popular food types giving priority only for taste. It is questionable why such gap is exist in the society. Therefore, this research mainly focuses on identifying whether there is real demand from consumer side for healthy meal.This research has been conducted under positivism and deductive research approach. Data have been collected using survey from selected respondents. In addition to that, findings of secondary sources have beenused to interpret survey results. Results of the survey clearly indicates that there is a real demand for healthy food in the society. Most of people are looking for healthy food irrespective of their age, occupation or health. Though there is such demand, the market is failed to satisfy it. This situation creates a latent demand in the market. People looking for trusted food vendor who can provide healthy food at a reasonable price. Though people prefer healthy meal, majority of them expect those foods to be tasty. Therefore, if a vendor focuses only on healthiness of the meal, then there is a risk that he will be fail in the market. Unless if consumers have critical health issues, they will not purchase foods which are less in taste compared to the normal food. Keywords: Consumer Attitude, Healthy food, Taste, Purchase
Heterogeneously catalyzing C–C coupling reactions with precious metal nanoparticles

C–C coupling reactions are ubiquitous in synthetic chemistry, joining together fragments of larger molecules within overall synthetic schemes. Many obvious operational advantages would result from catalyzing such processes heterogeneously, however, there has been much controversy over whether metal nanoparticles (typically Pd) can be used in this role, or if catalysis in such cases occurs instead on metal ions leached into solution. In this mini-review selected examples of attempts to distinguish the homo- or hetero-geneity of such reactions, using Pd and Au nanoparticles, are highlighted. In particular, several interesting recent results are explored that demonstrate such metal nanoparticle catalyzed reactions can occur in a heterogeneous mode.

Trade, the Environment, and Impacts on State Agricultural Exports

International trade theory predicts that the relative level of a country’s resource endowments, trade policy, environmental regulations, and level of technology would jointly determine production specialization and trade pattern of the country. This study develops state export share and alternative environmental risk models to evaluate the effects of resource endowments, prices, and environmental risk factors on agricultural exports and environment. A simultaneous system of the environmental risk and export share models was estimated by using the nonlinear estimation method outlined in RATS (2009). The results reveal that crop prices, state GDP, state farm GDP and technological changes were found to be major determinants of the state export shares. The results also suggest that NAFTA had no negative effect on the environment. The study found that the European Union (EU) and expansion of its membership led to significant reduction in state agricultural exports due mainly to the effect of trade diversion in the EU expansion.
Estimating Impact of a Continuous Program under a Conditional Independence Assumption

Traditional literature on impact evaluation often deals with binary programs. In reality, a program can provide different amounts of treatment for people, and it is regarded as a continuous variable. This paper discusses impact evaluation of a continuous program using matching methods and illustrates how to estimate impact of foreign remittances on per capita expenditure in Vietnam.
Socio-economic stratification of life satisfaction in Ireland during an economic recession: A repeated cross-sectional study using the European Social Survey

Life satisfaction is an understudied topic in literature on socio-economic stratification. Using the European Social Survey data, this study concentrates on the recent economic recession in Ireland, and the socio-economic stratification of life satisfaction before and during economic crisis. We measure stratification multidimensionally using education, occupational social class and income. The results show that the effects of the crisis, which peaked in 2010 in terms of both GDP and life satisfaction, are not experienced equally within the population. Lower strata (lowest income quartile, manual workers and those with basic education at most) are more affected. In the pre-crisis period, life satisfaction appeared to be stratified mostly by income, which was due to the experience of economic hardship. However, during the crisis stratification of life satisfaction took a more complex and deeper form and also basic education and manual labour then began to explain lower life satisfaction.

HABITAT USE BY BLACK RAT SNAKES (ELAPHE OBSOLETA OBSOLETA) IN FRAGMENTED FORESTS

Declining nest success of forest birds in fragmented habitat has been attri- buted to increased nest predation. Better understanding of this problem and potential so- lutions to it require information on why nest predators are attracted to habitat edges. Toward this end we investigated habitat use by black rat snakes (Elaphe obsoleta obsoleta), an important avian-nest predator in eastern deciduous forests. We radio-tracked 52 black rat snakes for periods of 3-41 mo from 1996 to 1999. All black rat snakes exhibited a strong preference for edge habitats. Consistent with edges being used because they facilitate thermoregulation, gravid females associated more strongly with edges than did males and nongravid females, and sites used by snakes when shedding were significantly associated with habitat edges. Gravid females lost an average of >20% of their body mass, while nongravid females and males did not lose mass, suggesting that edges were not used because they offered high success in foraging. Similarly, an increase in use of edge habitat through the season by all rat snakes was inconsistent with the snakes being attracted principally to hunt: avian prey would have been more abundant in spring when birds were breeding, and the density of small mammals in edges did not vary seasonally. Also, snakes moved longer distances and were found traveling.more often when located in forests. Because our results collectively are most consistent with the hypothesis that rat snakes use edges for ther- moregulatory reasons, the negative impact of the snakes on nesting birds may be coinci- dental; the snakes primarily use edges for reasons other than foraging but opportunistically exploit prey they encounter there. Rat snakes appeared to respond to the edge structure rather than to how the edge was created (natural vs. artificial). Thus, fragmentation of forests by humans has created habitat structurally similar to that preferred by rat snakes in their natural habitat, thereby inadvertently increasing contact between the snakes and nesting birds.
Assessing the efficacy and effectiveness of a Positive Psychology-based self-help book

El presente articulo analiza la utilidad potencial de los libros de auto-ayuda como medio de difusion de las intervenciones psicologicas positivas, y presenta datos comparando libro de autoayuda basado en psicologia positiva, un libro de autoayuda cognitivo-conductual, y una condicion de control de auto-monitorizacion. Participaron estudiantes universitarios de primer ano (N = 58), y defendemos que esta poblacion es un objetivo particularmente apropiado para intervenciones centradas en el bienestar. Las medidas de resultado incluyeron tanto indices de eficacia (sintomas depresivos y satisfaccion con la vida) como de efectividad (por ejemplo, el grado en el que los participantes juzgaron que sus actividades asignadas tenian sentido). Los dos grupos de libros superaron al grupo control y fueron igualmente eficaces en la reduccion de los sintomas. Respecto a la satisfaccion vital, el grupo de autoayuda positiva supero al cognitivo-conductual, pero solo a los 6 meses de seguimiento. La intervencion positiva de auto-ayuda tambien fue superior a la cognitivo-conductual en los indices de efectividad. Se discuten las posibilidades de futuras direcciones, enfatizando las realidades de la difusion practica tanto en estudiantes universitarios como al publico en general.
Virtual Code Resource Allocation Approach for Energy-Aware access of Machine-Type Communications over 5G Smart City

The enormous tra ﬃ c of machine-type communications(MTC) expected over 5G smart city environments exacerbates the limitations of access schemes currently under investigation in literature. This becomes more challenging when considering the heterogeneity in the level of residual battery energy of machines and dictates novel solutions aiming at drastically reducing the collision probability of devices with critical level of residual battery energy. In this paper, we propose a virtual code resource allocation (VCRA) approach which extends the code-expanded strategy to support high number of devices simultaneously accessing the system and the virtual resource allocation scheme to introduce energy-priority in the access procedure. The idea behind our proposal is the deﬁnition of di ﬀ erent access levels that exploit disjoint sets of access codewords, properly tailored to guarantee high capacity for each access level. Simulation results testify the e ﬀ ectiveness of our scheme in terms of (i) reducing the collision probability of machines with limited battery capabilities also in scenario with very huge cell load and (ii) enhancing the e ﬃ ciency with respect to legacy code-expanded strategy.
Translating Collocations from English to Arabic among Iraqi EFL Learners

This paper will thoroughly examine the notion of collocation and will analyse translations of English collocations into Arabic while detailing other related points. It will also incorporate a detailed explanation of the various types of collocations in English. A collocation is defined as a combination of two or more words that usually occur together in different language contexts. Although there have been many published literatures on collocation, there is limited examination of collocation in Iraq, and the specific problems faced by Iraqi EFL students translating English collocations into Arabic. This study examines the effect of mother tongue interference on the translation of English collocations into Arabic among Iraqi EFL students. The results reveal that 67% of the participants failed to achieve the pass mark, and only 33% achieved an acceptable level of understanding and translation. A detailed explanation of the results will be presented, as well as a conclusion and recommendation of this study.
Comparison of callus induction and plant regenerationfrom twenty tall fescue varieties

Tall fescue (Festuca arundinacea Schreb.) is an important grass species both as turf and forage. In this study, 20 varieties of tall fescue were used to investigate the effects of genetic variations in tissue culture response. Plant genotype had a significant effect both on callus formation and plant regeneration in tall fescue. The forage type tall fescue varieties readily formed callus than turf type tall fescue varieties. Of all the forage varieties studied, Jesup, Greenmaster, Kentucky-31 and Fawn not only formed callus at a higher frequency but also had a high regeneration when compared with other varieties. These results can be used not only to provide additional improvements in the plant regeneration frequency from transgenic callus, but also useful for molecular breeding of tall fescue through genetic transformation.
Detection of Mycobacterium avium subspecies paratuberculosis excretion in bovine feces, using quantitative real time polymerase chain reaction (Q-PCR)

Mycobacterium avium subspecies paratuberculosis (Map) causes paratuberculosis, an infectious enteritis that affects domestic ruminants. The main source of infection for herds comes from the elimination of the bacilli through feces. The objective of this study was to determine Map excretion in bovine feces. The study included forty, one-year-old bovine, Holstein breed females, from a herd that had >25% paratuberculosis prevalence. Samples of blood and feces were obtained four times with three-month intervals. Feces samples were subjected to bacteriological culture and DNA extraction for IS900 quantitative real time polymerase chain reaction (Q-PCR). Enzyme-linked immunosorbent assay (ELISA) was done from serum samples to detect the presence of anti-Map antibodies. Correlation between IS900 Q-PCR, culture and ELISA was established by the Kappa (K) test; statistical analysis was carried out by the Pearson Chi2 test. On the first sampling, five animals were detected by IS900 Q-PCR, shed 1 × 102 to 2.6 × 103 Map copies per gram of feces; on the second sampling, 6 animals shed 3.25 × 104 to 8.5 × 108; on the third sampling two animals shed 2.03 × 105 to 1.10 × 106 and on the fourth, three animals shed 7.92 × 104 to 1.4 × 107 Map copies. Correlation between tests in samplings first, second and fourth, was 0.53 to 0.73, and for third was 0.22. With the use of IS900 Q-PCR, it was possible to detect animals that were eliminating Map in feces from 12 months of age without clinical manifestations. The IS900 Q-PCR is an alternative method to carry out programs of control of paratuberculosis that allow the detection of animals that shed Map in the early stages of the infection. Key words: Paratuberculosis, Mycobacterium avium subspecies paratuberculosis, excretion, quantitative polymerase chain reaction (Q-PCR), bacteriological culture, enzyme-linked immunosorbent assay (ELISA).
Double Sided Moral Hazard and Share Contracts in agriculture

This paper develops a double-sided moral hazard model of share contract in agriculture, with imperfect quality measurement by the agent and the principal, who contribute to the final good quality in terms of production effort and marketing effort respectively. Using this model, we analyse the implications of the share contract for quantity and quality, often ignored in previous analysis. With the help of a simulation exercise, we prove that the outcome-conditioned share generally weakens the agent´s incentive to make effort in quality input. This finding could explain the contractual evidence in some differentiated markets such as the wine market, where bottle-price conditioned contracts are rarely used.
Kyushu University Institutional Repository SELECTION OF ARX MODELS ESTIMATED BY THE PENALIZED WEIGHTED LEAST SQUARES METHOD

We consider the selection problem of auto-regressive time-series models with eXogeneous variables (ARX) estimated by Penalized Weighted Least Squares (PWLS) method. AIC and BIC are developed based on the maximum likelihood estimation. Therefore, in this research, we evaluate GIC for the ARX models estimated by PWLS. In a numerical experiment, the model selected by GIC shows an excellent performance, especially, in a target region.
