U ovom je radu opisana ranjivost obala otoka Raba koja može biti prouzročena prognoziranim porastom razine mora do kraja 21. stoljeća. Opisane su posljedice koju taj prirodni fenomen može prouzročiti. Analizirana su tri scenarija pojava visoke razine mora: kod stagnacije globalne morske razine te kod porasta za 30 i 60 cm. Analize su napravljene na topografskim kartama mjerila 1:5000. Ustanovljene su najugroženije urbanizirane obalne zone: uvala Sv. Eufemija, luka grada Raba, Supetarska Draga...
Full Text Available Procjene za prosječan porast morske razine na globalnoj razini do kraja 21. stoljeća najčešće variraju od 0,18 m do ≥ 1 m u odnosu na današnju razinu. Ako se razmatraju procjene koje obuhvaćaju i otapanje grenlandskog i antarktičkog ledenog pokrova, tada se može očekivati porast morske razine od 5 i više m. Sukladno s globalnim promjenama, razina Jadranskog mora također je u porastu. Radi analize potencijalne ugroženosti hrvatske obale od porasta morske razine, izrađena su tri modela porasta razine Jadranskog mora (od 1 m, 3 m i 6 m. Na temelju modela analizira se utjecaj porasta morske razine na različite socioekonomske segmente obalnog prostora. Cilj je istraživanja definirati najugroženije dijelove hrvatske obale. Kako bi se mogli diferencirati najugroženiji dijelovi, izrađen je Indeks ugroženosti obalnih općina ( . U izradi Indeksa koristili su se analizom utjecaja dobiveni kvantitativni podaci o prostornom obuhvatu poplavnih zona te ugroženosti stanovništva i prometne infrastrukture obalne zone. Navedenim su varijablama s pomoću Analitičkog hijerarhijskog procesa (AHP pridruženi različiti težinski koeficijenti, ovisno o važnosti varijable. Pri analizi svih triju modela uočeno je kako se Zadar i njegova okolica ističu kao najugroženije područje hrvatske obale. Zbog toga je na primjeru Zadra izvršena znatno detaljnija analiza mikrolokacijskog utjecaja porasta morske razine. Podaci dobiveni analizom različitih modela pokazuju kako je gotovo cijela hrvatska obala ugrožena, ali i da postoji velik nerazmjer u razini ugroženosti pojedinih dijelova hrvatske obale. Važnost je ovog istraživanja u tome što ono predstavlja temelj za pravovremenu adaptaciju na negativne utjecaje budućeg porasta razine Jadranskog mora.
There exists a great gap between one-time pad with perfect secrecy and conventional mathematical encryption. The Yuen 2000 (Y00) protocol or αη scheme may provide a protocol which covers from the conventional security to the ultimate one, depending on implementations. This paper presents the complexity-theoretic security analysis on some models of the Y00 protocol with nonlinear pseudo-random-number-generator and quantum noise diffusion mapping (QDM). Algebraic attacks and fast correlation attacks are applied with a model of the Y00 protocol with nonlinear filtering like the Toyocrypt stream cipher as the running key generator, and it is shown that these attacks in principle do not work on such models even when the mapping between running key and quantum state signal is fixed. In addition, a security property of the Y00 protocol with QDM is clarified. Consequently, we show that the Y00 protocol has a potential which cannot be realized by conventional cryptography and that it goes beyond mathematical encryption with physical encryption

Full Text Available In her recent work, Sau-ling Cynthia Wong draws critical attention to the implications of the formation of an Asian American “diaporic community” in cyberspace, where race still operates as an organizing principle of power relations. Although cyberspace is not confined by national borders, Wong examines how subversion of and intervention in race- and sex-based hierarchies in cyberspace can articulate Asian American identities in relation to diasporas and the nation-state. This essay explores the politics of artistic invention in diasporas as embedded in the disruption, dislocation, and fragmentation in Ming-Yuen S. Ma’s multi-media project, Xin Lu: A Travelogue in Four Parts—a series of four experimental videos about Chinese diasporas. It argues that by moving outside the nation-space into the experiential and virtual “global space” of diasporas, Ma’s work addresses Wong’s concerns and enacts a viable “virtual mediation” that situates Chinese diasporas in the historical contexts of British colonialism and American racial exploitation and exclusion. This movement also entails confronting other forms of oppression, including sexism and heterosexism in both the East and West. While giving voice and visibility to the struggles of racial and sexual minorities across national borders, Ma demonstrates the possibilities of a historicized critical approach to diasporas, one which underlies Wong’s insistence in critiquing gendered and racialized power structures both within and outside the nation-state.

Full Text Available Adlay (薏苡 yì yĭ; “soft-shelled job’s tears”, the seeds of Coix lachryma-jobi L. var. ma-yuen Stapf is a grass crop that has long been used in traditional Chinese medicine (TCM and as a nourishing food in China for the treatment of warts, chapped skin, rheumatism, neuralgia, inflammatory, and neoplastic diseases. In addition, adlay also has been said to have stomachic, diuretic, antipholgistic, anodynic, and antispasmodic effects. Carcinogenesis is a multistage process that begins with exposure of viruses or chemicals that are found in the environment. Chemoprevention refers to the use of natural or synthetic, non-toxic chemical substances to reverse, repress, or prevent carcinogenesis. In this review, we summarize recent research attempting to study the chemopreventive blocking and suppressing potential of adlay and its active components in scavenging electrophiles and reactive oxygen species, antimutagenicity, enhancing Nrf2-mediated detoxification and antioxidant effect, altering carcinogen metabolism, suppressing proliferation, decreasing inflammation, and enhancing antitumor immunity. In addition, several active components with diverse chemopreventive properties have been also mentioned in this review article.

Adlay has long been used in traditional Chinese medicine and as a nourishing food. The acetone extract of adlay hull had previously been demonstrated to possess potent antimutagenic activity. The aims of this study were to identify the antimutagenic constituents from adlay hull by using Ames antimutagenic activity-guide isolation procedures and to investigate their chemopreventive efficacies in cultured cells. The results demonstrated that six compounds showing great antimutagenic activity were identified by spectroscopic methods and by comparison with authentic samples to be p-hydroxybenzaldehyde, vanillin, syringaldehyde, trans-coniferylaldehyde, sinapaldehyde, and coixol. Two of them, trans-coniferylaldehyde and sinapaldehyde, exhibit relatively potent scavenging of DPPH radicals, inhibit TPA stimulated superoxide anion generation in neutrophil-like leukocytes, and induce Nrf2/ARE-driven luciferase activity in HSC-3 cells. Moreover, trans-coniferylaldehyde possesses cytoprotective efficacy against tert-butyl hydroperoxide-induced DNA double-strand breaks in cultured cells, and the chemopreventive potency induced by trans-coniferylaldehyde may be through the activation of kinase signals, including p38, ERK1/2, JNK, MEK1/2, and MSK1/2. In summary, we first identified six antimutagenic constituents from adlay hull. Among them, trans-coniferylaldehyde would be a highly promising agent for cancer chemoprevention and merits further investigation.

The current study aims to investigate the antioxidant activities of various extracts from defatted adlay seed meal (DASM) based on the oxygen radical absorbance capacity (ORAC) assay, peroxyl radical scavenging capacity (PSC) assay and cellular antioxidant activity (CAA) assay. Of all the fractions, the n-butanol fraction exhibited the highest antioxidant activity, followed by crude acetone extract and aqueous fractions. Of the three sub-fractions obtained by Sephadex LH-20 chromatography, sub-fraction 3 possessed the highest antioxidant activity and total phenolic content. There was a strong positive correlation between the total phenolic content and the antioxidant activity. Based on HPLC-DAD-ESI-MS/MS analysis, the most abundant phenolic acid in sub-fraction 3 of DASM was ferulic acid at 67.28 mg/g, whereas the predominant flavonoid was rutin at 41.11 mg/g. Of the major individual compounds in sub-fraction 3, p-coumaric acid exhibited the highest ORAC values, and quercetin exhibited the highest PSC values and CAA values. Copyright © 2015 Elsevier Ltd.

Text categorization is a process of assigning labels to documents according to the contents or topics of the documents. Traditionally text categorization is carried out by human experts. However, due to factors such as blurred category boundaries, background bias, and personal judgment, label inconsistency is often found in human classified collections, thus reducing their values in various applications. This article described an automatic process to detect such inconsistency based on the Agricultural Science Information Center (ASIC collection. In the article, important examples and results are presented. Potential benefits and applications are discussed.

We present a model of investment under uncertainty about fundamentals, using a global games approach. Goldstein & Razin (2003) show that there is an information based trade-off between foreign direct investment (FDI) and portfolio investment (PI) which rationalizes some well known stylised facts in the literature - the relative volatility and reversibility of foreign direct investment versus portfolio investment. We extend their result and show that uncertainty about fundamentals does not imp...

The recent literature on economies with an incomplete set of markets has been devoted to the study of the efficiency properties of collective stockholder decision mechanisms for guiding the behavior of firms when the restrictive Ekern-Wilson spanning condition is not satisfied. The results have been essentially negative; a majority voting rule and controlling interest rules will not yield efficient equilibrium allocations in general. However, in a recent paper, Helpman and Razin (1978) sugges...

In this paper, we investigate the analytical solutions of the compressible Navier-Stokes equations with dependent-density viscosity. By using the characteristic method, we successfully obtain a class of drifting solutions with elliptic symmetry for the Navier-Stokes model wherein the velocity components are governed by a generalized Emden dynamical system. In particular, when the viscosity variables are taken the same as Yuen [M. W. Yuen, “Analytical solutions to the Navier-Stokes equations,” J. Math. Phys. 49, 113102 (2008)], our solutions constitute a generalization of that obtained by Yuen. Interestingly, numerical simulations show that the analytical solutions can be used to explain the drifting phenomena of the propagation wave like Tsunamis in oceans

Full Text Available This paper analyzes reports written by foreign authors about the execution of Stepan Razin. The main focus is on two dispatches written by the Swedish citizen and merchant in Moscow, Christoff Koch, in May–June 1671 and sent to Narva, and from there, they were forwarded to the Swedish capital, among other places. They are now kept at the State Archives in Stockholm, and they have not been discussed previously in the scholarly literature. The paper contains the full translation into Russian of two long reports written by Koch about Razin’s capture, delivery to Moscow, interrogation, and execution, with our comments. Special attention is given to a unique colored drawing, showing the brothers, Stepan and Frol Razin, as well as the body parts of the executed Stepan. From the written documents it becomes clear that the drawing was sent from Moscow to the governor of Swedish Ingria in Narva, and then forwarded to Stockholm, together with the two Koch dispatches. The authors come to the conclusion that several copies must have been made and that they were intentionally distributed among foreigners in Moscow. Most probably only one copy has survived to our days, the one in Stockholm. Arguments are given for the hypothesis that one copy of the drawing ended up in England and served as the prototype for the well-known imprint of 1672, which shows the Razin brothers when they were being delivered to Moscow. In our study we also compare the information given by Koch with descriptions of Razin’s death that were published in West-European newspapers, pamphlets, and books during the 1670s. This comparison brings us to the conclusion that the information about the execution of the leader of the rebellion reached the European press from several witnesses to the events, and that, over time, the original information was filled out with invented details.

The steady-state drag of evaporating or condensing droplets in low Reynolds number flow is computed. Droplet drag in air is obtained for five representative liquids (water, methanol, benzene, heptane, octane) for a range of ambient temperatures, pressures, and vapor concentrations. The drag is in general increased for a condensing droplet, and decreased for an evaporating droplet. The changes in drag can be quite large and depend in detail on the degree of evaporation or condensation, and on the individual liquid and vapor properties. The present results are used to test the existing experimentally derived correlations of Eisenklam and Yuen and Chen in the low Reynolds number regime. The Yuen and Chen correlation is found to be quite successful, but only in the case of condensation or mild evaporation. An improved correlation is suggested for evaporating droplets

A novel implementation of quantum-noise optical cryptography is proposed, which is based on a simplified architecture that allows long-haul, high-speed transmission in a fiber optical network. By using a single multiport encoder/decoder and 16 phase shifters, this new approach can provide the same confidentiality as other implementations of Yuen's encryption protocol, which use a larger number of phase or polarization coherent states. Data confidentiality and error probability for authorized and unauthorized receivers are carefully analyzed.

Full Text Available The terms-of-trade shocks are not main source of business cycles in three post-communist countries (i.e., Slovakia, the Czech Republic, and Croatia. The zero or negative reactions of the trade balance in terms-of-trade positive shocks in the countries exhibit the Obstfeld-Svensson-Razin effect, according to which the Harberger-Laursen-Metzler positive effect on terms-of-trade indicates that the smaller the trade balance, the more persistent the terms-of-trade shock is. The conclusions come from the structural vector autoregressive analysis of the cyclical components of terms-of-trade, trade balance, output, consumption, and investment in three post-communist countries.

When planning a study, sample size determination is one of the most important tasks facing the researcher. The size will depend on the purpose of the study, the cost limitations, and the nature of the data. By specifying the standard deviation ratio and/or the sample size ratio, the present study considers the problem of heterogeneous variances and non-normality for Yuen's two-group test and develops sample size formulas to minimize the total cost or maximize the power of the test. For a given power, the sample size allocation ratio can be manipulated so that the proposed formulas can minimize the total cost, the total sample size, or the sum of total sample size and total cost. On the other hand, for a given total cost, the optimum sample size allocation ratio can maximize the statistical power of the test. After the sample size is determined, the present simulation applies Yuen's test to the sample generated, and then the procedure is validated in terms of Type I errors and power. Simulation results show that the proposed formulas can control Type I errors and achieve the desired power under the various conditions specified. Finally, the implications for determining sample sizes in experimental studies and future research are discussed.

The security issue for the next generation optical network which realizes Cloud Computing System Service with data center" is urgent problem. In such a network, the encryption by physical layer which provide super security and small delay should be employed. It must provide, however, very high speed encryption because the basic link is operated at 2.5 Gbit/sec or 10 Gbit/sec. The quantum stream cipher by Yuen-2000 protocol (Y-00) is a completely new type random cipher so called Gauss-Yuen random cipher, which can break the Shannon limit for the symmetric key cipher. We develop such a cipher which has good balance of the security, speed and cost performance. In SPIE conference on quantum communication and quantum imaging V, we reported a demonstration of 2.5 Gbit/sec system for the commercial link and proposed how to improve it to 10 Gbit/sec. This paper reports a demonstration of the Y-00 cipher system which works at 10 Gbit/sec. A transmission test in a laboratory is tried to get the basic data on what parameters are important to operate in the real commercial networks. In addition, we give some theoretical results on the security. It is clarified that the necessary condition to break the Shannon limit requires indeed the quantum phenomenon, and that the full information theoretically secure system is available in the satellite link application.
Full Text Available This paper considered a dependent discrete-time risk model, in which the insurance risks are represented by a sequence of independent and identically distributed real-valued random variables with a common Gamma-like tailed distribution; the ﬁnancial risks are denoted by another sequence of independent and identically distributed positive random variables with a ﬁnite upper endpoint, but a general dependence structure exists between each pair of the insurance risks and the ﬁnancial risks. Following the works of Yang and Yuen in 2016, we derive some asymptotic relations for the ﬁnite-time and inﬁnite-time ruin probabilities. As a complement, we demonstrate our obtained result through a Crude Monte Carlo (CMC simulation with asymptotics.

The stability of plane, periodic solutions of the two-dimensional nonlinear Schroedinger equation to infinitesimal, two-dimensional perturbation has been calculated and verified numerically. For standing wave disturbances, instability is found for both odd and even modes; as the period of the unperturbed solution increases, the instability associated with the odd modes remains but that associated with the even mode disappears, which is consistent with the results of Zakharov and Rubenchik, Saffman and Yuen and Ablowitz and Segur on the stability of solitons. In addition, we have identified travelling wave instabilities for the even mode perturbations which are absent in the long-wave limit. Extrapolation to the case of an unperturbed solution with infinite period suggests that these instabilities may also be present for the soliton. In other words, the soliton is unstable to odd, standing-wave perturbations, and very likely also to even, travelling-wave perturbations. (orig.)

We calculate the isentropic evolution of an instantaneously heated foil, assuming a van der Waals equation of state with the Maxwell construction. The analysis by Yuen and Barnard [Phys. Rev. E 92, 033019 (2015), 10.1103/PhysRevE.92.033019] is extended for the particular case of three degrees of freedom. We assume heating to temperatures in the vicinity of the critical point. The self-similar profiles of the rarefaction waves describing the evolution of the foil display plateaus in density and temperature due to a phase transition from the single-phase to the two-phase regime. The hydrodynamic equations are expressed in a dimensionless form and the solutions form a set of universal curves, depending on a single parameter: the dimensionless initial entropy. We characterize the rarefaction waves by calculating how the plateau length, density, pressure, temperature, velocity, internal energy, and sound speed vary with dimensionless initial entropy.

We present wintertime variations and distributions of sea surface temperature (SST) fronts in the Taiwan Strait by applying an entropy-based edge detection method to 10-year (1996-2005) satellite SST images with grid size of 0.01°. From climatological monthly mean maps of SST gradient magnitude in winter, we identify four significant SST fronts in the Taiwan Strait. The Mainland China Coastal Front is a long frontal band along the 50-m isobath near the Chinese coast. The sharp Peng-Chang Front appears along the Peng-Hu Channel and extends northward around the Chang-Yuen Ridge. The Taiwan Bank Front evolves in early winter. As the winter progresses, the front becomes broad and moves toward the Chinese coast, connecting to the Mainland China Coastal Front. The Kuroshio Front extends northeastward from the northeastern tip of Taiwan with a semicircle-shape curving along the 100-m isobath.

Full Text Available In this paper we summarize the main idea and results of Yuen and Yang (2009, 2010a, 2010b and provide some results on pricing of Parisian options under the Markov regime-switching model (MRSM. The MRSM allows the parameters of the market model depending on a Markovian process, and the model can reflect the information of the market environment which cannot be modeled solely by linear Gaussian process. However, when the parameters of the stock price model are not constant but governed by a Markovian process, the pricing of the options becomes complex. We present a fast and simple trinomial tree model to price options in MRSM. In recent years, the pricing of modern insurance products, such as Equity-Indexed annuity (EIA and variable annuities (VAs, has become a popular topic. We show here that our trinomial tree model can been used to price EIA with strong path dependent exotic options in the regime switching model.

Full Text Available Influence of calmodulin antagonists on mitochondrial membrane potential was investigated using a flow cytometry method, confocal microscopy and fluorescent potential-sensitive probes TMRM and MTG. Influence of different concentrations of calmodulin antagonists on mitochondrial membrane potential was studied using flow cytometry method and a fraction of myometrium mitochondria of unpregnant rats. It was shown that 1-10 µМ calmidazolium gradually reduced mitochondria membrane potential. At the same time 10-100 µМ trifluoperazine influenced as follows: 10 µМ – increased polarization, while 100 µМ – caused almost complete depolarization of mitochondrial membranes. In experiments which were conducted with the use of confocal microscopy method and myometrium cells it was shown, that MTG addition to the incubation medium led to the appearance of fluorescence signal in a green range. Addition of the second probe (ТМRM resulted in the appearance of fluorescent signal in a red range. Mitochondrial membrane depolarization by 1µМ СССР or 10 mМ NaN3 was accompanied by the decline of “red” fluorescence intensity, “green” fluorescence was kept. The 10-15 minute incubation of myometrium cells in the presence 10 µМ calmidazolium or 100 µМ trifluoperazine was accompanied by almost complete decrease of the TMRM fluorescent signal. Thus, with the use of potential-sensitive fluorescent probes TMRM and MTG it was shown, that calmodulin antagonists modulate mitochondrial membrane potential of myometrium cells.

During necking of a mechanically stiffer layer embedded in a weaker matrix, relatively large amounts of strain localize in small areas. As this deformation style appears under distinct geological conditions, necking phenomena, e.g. boudinaged veins, are associated with a variety of deformation modes. So far, there exists rather limited knowledge about the origin of instabilities and their role as precursory structures, i.e. strong localization of elastic energy affecting further plastic deformation (e.g. Regenauer-Lieb & Yuen, 1998; 2004; Karrech et al., 2011a). We applied the finite element solver ABAQUS in order to investigate the 2-D strain distribution in layers including different mechanical material properties during plane strain co-axial deformation. First, linear perturbation analyses were performed in order to evaluate the imperfection sensitivity in the elastic and viscous regimes. We perform a classical modal analysis to determine the natural mode shapes and frequencies of our geological structure during arbitrary vibrations. This analysis aims at detecting the eigenmodes of the geological structure, which are sinusoidal vibrations with geometry specific natural modal shapes and frequencies. The eigenvalues represent the nodal points where the onset of (visco)-elasto-plastic localization can initiate in the structure (Rice, 1977). The eigenmodes, eigenvalues and eigenvectors are highly sensitive to the layer-box' aspect ratio and differences in Young's moduli, or effective viscosity, respectively. Boundary effect-free strain propagation occurs for layer-box aspect ratios smaller than 1:10. Second, these preloading structures were used as seeds for imperfections in elasto-viscoplastic numerical modeling of continuous necking of a coarse-grained mineral layer embedded in a finer-grained matrix (pinch-and-swell type of boudinage), following the thermo-mechanical coupling of grain size evolutions by Herwegh et al. (in press). The evolution of symmetric necks

Layered rocks deformed under viscous deformation conditions frequently show boudinage, a phenomenon that results from differences in effective viscosity between the involved layers. In the case of continuous necking of a mechanically stiffer layer embedded in a weaker matrix, symmetric boudins are interpreted as the result of dominant visco-plastic deformation (Goscombe et al., 2004). However, information on the physical conditions, material properties and deformation processes are yet unknown. Natural samples deformed under low-grade (TAustin and Evans (2007) combined with the thermodynamic approach of Regenauer-Lieb and Yuen (2004). Depending on the dissipated energy, grain sizes in these domains vary substantially in space and time. While low strain rates (low stresses) in the swells favor grain growth and GSI dominated deformation, high strain rates in the pinches provoke dramatic grain size reduction with an increasing contribution of GSS as a function of decreasing grain size. The development of symmetric necks observed in nature thus seems to coincide with the transition from dislocation to diffusion creep dominated flow with continuous grain size reduction and growth from swell to neck at relatively high extensional strains.

Full Text Available In the period of “new” imperialism in the late nineteenth and early twentieth centuries, France strived to create a sphere of influence in southwest China. To foster such imperialist policies, France’s policy makers regarded French companies operating in East Asia as instrumental. One such firm was Auguste Raphael Marty’s Tonkin Shipping Company, based in Haiphong, French Indochina, which operated steam coasters across the wider Gulf of Tonkin region. In the region’s highly competitive shipping market, Marty strived to achieve a monopoly when favorable conditions permitted during the final phase of the Sino-Japanese War. His profit-driven strategy caused huge losses for Chinese shippers and ultimately resulted in their boycotting his ships through the Tsap Yet syndicate. When French officials intervened on Marty’s behalf in negotiations with the Chinese government, the Syndicate was finally dissolved. It was followed by an agreement between the Chinese firm of Yuen Cheong Lee and Co. and the German firm of Jebsen and Co., based on long-established mutual trust between the owners. Although Marty received monetary compensation for his losses, he ruined his relationship with Chinese merchants. This case study presents little-known facts about the interactions among foreign firms in China and demonstrates the Chinese ability to react efficiently to unfair business practices.
Full Text Available Based upon long-term observations (1993 - 2010 of satellite-derived winter sea surface temperature (SST data, an exceptional cold-water intrusion into the southern Taiwan Strait (TS was noted in February 2008. In the winter of 2008, La Niña caused a strong and continuous northeasterly wind that drove the cold ocean current, the China Coastal Current, more southward to penetrate the southern TS north of the Chang-Yuen Ridge. A portion of this current turned eastward to the south of Penghu Islands (PHI. The low-SST event significantly impeded local marine aquaculture and wild fish, causing the death of more than 73 tons of fish around PHI. Comparing variations of the first quarterly catches in 2008 with the long-term averages from 1993 to 2010 (excluding 2008, we noted a 50 to 80% decrease in catches from pole-and-line, long-line, and gill-net fishery. Non-migratory species dominated the composition of the catches. We also noted a greater than 230% increase in the catches from set-net fishery, with the majority being migratory species. These results illustrate the positive and negative effects of cold-water intrusion on several fish communities and species.

This study aims to assess potential environmental influences on allergy development in children. Based on a parent-completed questionnaire survey administered in Hong Kong in 2003 in accordance with the International Study of Asthma and Allergies in Childhood protocol, the prevalence and incidence of asthma and rhinoconjunctivitis of 508 preschool children aged 4 to 6 years in Yuen Long District were determined and a range of indoor and outdoor environmental factors were assessed. Exposure to moisture and mold in the first year of life increased the risk of asthma (adjusted odds ratio [aOR] = 2.56; 95% confidence interval [CI] = 1.40-4.68) and rhinoconjunctivitis (aOR = 2.09; 95% CI = 1.15-3.80). Current maternal smoking was also associated with a higher prevalence of asthma (aOR = 2.00; 95% CI = 1.04-3.84). No association was observed between outdoor traffic-related air pollutants and the prevalence of the allergic conditions. Indoor home environments had a stronger influence on allergy development, whereas exposure to traffic-related external environment gave a variable effect, the significance of which would be difficult to be substantiated. © 2011 APJPH.

Recently, it has been hypothesized that glial activation may be a contributor to migraine; therefore, this study investigated whether the potential glial inhibitor, ibudilast, could attenuate CM. Methods: The study was of double-blind, randomized, placebo-controlled, two-period crossover design. Participants were randomized to receive either ibudilast (40 mg twice daily or placebo treatment for 8 weeks. Subsequently, the participants underwent a 4-week washout period followed by a second 8-week treatment block with the alternative treatment. CM participants completed a headache diary 4 weeks before randomization throughout both treatment periods and 4 weeks after treatment. Questionnaires assessing quality of life and cutaneous allodynia were collected on eight occasions throughout the study. Results: A total of 33 participants were randomized, and 14 participants completed the study. Ibudilast was generally well tolerated with mild, transient adverse events, principally nausea. Eight weeks of ibudilast treatment did not reduce the frequency of moderate to severe headache or of secondary outcome measures such as headache index, intake of symptomatic medications, quality of life or change in cutaneous allodynia. Conclusion: Using the current regimen, ibudilast does not improve migraine with CM participants. Keywords: chronic migraine, glia, ibudilast, headache, immune system

Full Text Available Occupation, blockage and storming are not rare in social movements a decade after China resuming sovereignty in Hong Kong. The organizers and participants usually involve locally born young people. Some of them are secondary school students in their teens. They are known as the fourth generation or post-1980s born Hongkongers. The paper examines the cultural context of social movements involving these youth activists. It mainly studied the campaign against the Sino-Hong Kong Express Railway development project. The project called for the demolition of the Tsoi Yuen Village, a small rural village located on its designed route. Since then, the role of younger generation in social movements has been generally recognized. Social media are widely employed in all stages of the movements with citizen journalists actively involved. The impressive ‘prostrating walk’ imitating Tibetan pilgrims becomes the symbol of these youth activists. It keeps appearing in other campaigns including Occupy Central in Hong Kong in 2014. This paper argues that the rise of nativism, advancement in ICT technology and shifting towards new social movements contribute to the dominant role of youth in recent social movements of Hong Kong. Collective identity of Hongkonger in response to the top-down assimilation by China, strengthens the movement.

There are heuristic arguments proposing that the accuracy of monitoring position of a free mass m is limited by the standard quantum limit (SQL): σ2( X (t ) ) ≥σ2( X (0 ) ) +(t2/m2) σ2( P (0 ) ) ≥ℏ t /m , where σ2( X (t ) ) and σ2( P (t ) ) denote variances of the Heisenberg representation position and momentum operators. Yuen [Phys. Rev. Lett. 51, 719 (1983), 10.1103/PhysRevLett.51.719] discovered that there are contractive states for which this result is incorrect. Here I prove universally valid rigorous quantum limits (RQL), viz. rigorous upper and lower bounds on σ2( X (t ) ) in terms of σ2( X (0 ) ) and σ2( P (0 ) ) , given by Eq. (12) for a free mass and by Eq. (36) for an oscillator. I also obtain the maximally contractive and maximally expanding states which saturate the RQL, and use the contractive states to set up an Ozawa-type measurement theory with accuracies respecting the RQL but beating the standard quantum limit. The contractive states for oscillators improve on the Schrödinger coherent states of constant variance and may be useful for gravitational wave detection and optical communication.

We have extended our previous 2D method [Gerya, T.V., Yuen, D.A., 2003. Characteristics-based marker-in-cell method with conservative finite-differences schemes for modeling geological flows with strongly variable transport properties. Phys. Earth Planet. Interiors 140, 295-320], which is a combination of conservative finite-differences with marker-in-cell techniques to include the effects of visco-elasto-plastic rheology, self-gravitation and a self-consistently derived evolving curvilinear planetary surface. This code is called I2ELVIS and can solve a new class of computationally challenging problems in geodynamics, such as shear localization with large strains, crustal intrusion emplacement of magmas, bending of realistic visco-elasto-plastic plates and core-formation by vigorous shell tectonics activities related to a global Rayleigh-Taylor instability of a metal layer formed around silicate-rich lower density (primordial) core during planetary accretion. We discuss in detail the computational strategy required the rheological constraints to be satisfied at each time step and spatial location. We show analytical benchmarks and examples drawn from comparing between numerical and analogue experiments in structural geology, subducting slab bending with a visco-elasto-plastic rheology and equilibrium spherical configurations from self-gravitation. We have also tested possibilities of future applications by addressing 3D geometries based on multigrid method and including inertial effects in the momentum equation with tracers in order to simulate meteoritic impact events and eventually earthquake instabilities.

Findings suggested that elderly people without concurrent cognitive stimulation could benefit from a memory-training program in the form of improved initiation and memory functioning. Self-rated quality of life measure also showed improvements alongside the cognitive benefits. Elderly people with regular concurrent cognitive stimulation, on the other hand, seemed to plateau in their level of performance and did not show any significant change.

Full Text Available All children need to grow up with a sense of belonging and security in order to maintain healthy relationships later in life (Erikson, 1969:239; McWhirten, 2007:189; Toerien, 2001:31. Belonging is a basic human need that has to be met before certain other needs, such as self-actualisation and self-esteem, can be fulfilled (Erikson, 1969:238; Maslow, 1970:43; Max-Neef, 1991:33. A lack of a sense of belonging leads to feelings of rejection, loneliness and an inability to engage in future relationships (Ding & Littleton, 2005:i. Children who do not experience this sense of belonging can easily become involved in gangster activities, promiscuity or substance dependence in order to secure a false sense of belonging (Brendtro, Brokenleg & Van Bockern, 2002:9. Ideally, this need for belonging should be fulfilled within the primary family situation. However, the reality is that many children in South Africa do not live in what is generally regarded as the primary family, namely a family with two parents (Holborn & Eddy, 2011:1, but come from fractured families. Children from fractured families in disadvantaged communities have more complex needs to be met in order to feel secure (Ding & Littleton, 2005:iii; Holborn & Eddy, 2011:7; Minuchin, Colapinto & Minuchin, 2007:10; Toerien, 2001:31; Yuen, 2005:7.

In psychology, outliers are often excluded before running an independent samples t test, and data are often nonnormal because of the use of sum scores based on tests and questionnaires. This article concerns the handling of outliers in the context of independent samples t tests applied to nonnormal sum scores. After reviewing common practice, we present results of simulations of artificial and actual psychological data, which show that the removal of outliers based on commonly used Z value thresholds severely increases the Type I error rate. We found Type I error rates of above 20% after removing outliers with a threshold value of Z = 2 in a short and difficult test. Inflations of Type I error rates are particularly severe when researchers are given the freedom to alter threshold values of Z after having seen the effects thereof on outcomes. We recommend the use of nonparametric Mann-Whitney-Wilcoxon tests or robust Yuen-Welch tests without removing outliers. These alternatives to independent samples t tests are found to have nominal Type I error rates with a minimal loss of power when no outliers are present in the data and to have nominal Type I error rates and good power when outliers are present.

Quantity and quality distribution of surface water and groundwater are changing under the impacts of both climate variability and human activities. The main goal of this paper is to evaluate the abovementioned impacts on the water resources in the Saveh plain, central Iran. To achieve this aim, spatial and temporal changes of the surface and groundwater quality and quantity have been analyzed, using hydrometric and meteorological data. The nonparametric Mann-Kendall test was used to identify trends and change points in the annual rainfall and runoff for the period of 1946 to 2011. In order to analyze the impacts of the Saveh Dam on runoff, the dam operation year, 1994, was considered as a change point. Mann-Kendall test results show that rainfall time series was divided into two parts, namely, 1966-1989 and 1990-2007, and averages of annual rainfall in five stations increase from 10 to 21 %. Also, runoff time series was divided into two parts, namely, 1946-1995 and 1996-2007 and averages of annual runoff in four stations decrease from 8 to 83 %. Results show that rainfall changes in Shahabasi, Razin, Jalayer, Emamabad, and Ahmadabad stations increased from 9 to 33 % before and after 1994. Nevertheless, runoff decreased from 24 to 81 %. The results indicate that the greatest lack of runoff between stations is at Shahabasi station and one important reason for the severe lack is operation of the Saveh Dam in 1994. Highest groundwater level decline, about 168.67 cm, occurred in 1994 that is the operation year of the Saveh Dam. Trend analysis of surface water quality show that electrical conductivity increased 957.34 μmho/cm before and after 1994. Also, the Wilcox water quality classification method has been reduced from C3-S1 to C4-S2. Average groundwater electrical conductivity (EC) during 1999-2003 and 2004-2009 increased to 89.6 μmho/cm. Also, the groundwater quality indices for agricultural usages are classified in four classes including, C4-S2 16, C4-S1 46, C3-S

The third part of the book includes four articles dealing with the applications of quantum squeezing. In the first article, Yuen presents a discussion of communications and measurement using squeezed states and discusses the advantages of using nonclassical light over classical light in communications and measurement. In the second article, Swain deals with the interaction of squeezed light with the atomic systems and presents a review of novel phenomena in spectroscopy. This chapter on two-level atomic system is followed by Ficek's article on squeezed-light based spectroscopy in three-level atomic systems. In the last article, Reid again addresses the advantages of squeezed light in communications, but her emphasis is different from that of Yuen's article. Here she discusses EPR correlations for squeezed light and presents squeezed-light based methods for quantum cryptography. All the authors are leading figures in the field of squeezed states who have made pioneering contributions to various aspects of the field over the years. This is reflected in the authoritative style with which all the articles are written. These articles are rich in content, easy to read and cover a broad base. The emphasis is however on the theoretical aspects with occasional references to experimental work. This book is an excellent collection of articles on quantum squeezing that are highly useful both for beginners who would like to learn about squeezing and its applications, as well as for experts who would like to learn about the frontiers.

To guarantee a security of Cloud Computing System is urgent problem. Although there are several threats in a security problem, the most serious problem is cyber attack against an optical fiber transmission among data centers. In such a network, an encryption scheme on Layer 1(physical layer) with an ultimately strong security, a small delay, and a very high speed should be employed, because a basic optical link is operated at 10 Gbit/sec/wavelength. We have developed a quantum noise randomied stream cipher so called Yuen- 2000 encryption scheme (Y-00) during a decade. This type of cipher is a completely new type random cipher in which ciphertext for a legitimate receiver and eavesdropper are different. This is a condition to break the Shannon limit in theory of cryptography. In addition, this scheme has a good balance on a security, a speed and a cost performance. To realize such an encryption, several modulation methods are candidates such as phase-modulation, intensity-modulation, quadrature amplitude modulation, and so on. Northwestern university group demonstrated a phase modulation system (α=η) in 2003. In 2005, we reported a demonstration of 1 Gbit/sec system based on intensity modulation scheme(ISK-Y00), and gave a design method for quadratic amplitude modulation (QAM-Y00) in 2005 and 2010. An intensity modulation scheme promises a real application to a secure fiber communication of current data centers. This paper presents a progress in quantum noise randomized stream cipher based on ISK-Y00, integrating our theoretical and experimental achievements in the past and recent 100 Gbit/sec(10Gbit/sec × 10 wavelengths) experiment.

This prospective study attempted to compare the effectiveness of a customized coordination exercise and a strength exercise in improving the cognitive functioning and physical mobility on the elderly.Methods: Participants from two centers for the elderly were allocated to practice either an 8-week coordination training (CT program or an 8-week towel exercise (TE program. The Chinese Mini-Mental State Examination and Chinese Dementia Rating Scale (CDRS were used to measure cognitive functioning of participants, and Timed Up-and-Go test for physical mobility. These assessments were administered before and after the program.Results: Paired t-tests showed that the CDRS scores of the CT group improved significantly from 114.8 at pre-test to 119.3 after training (P = 0.045. The CDRS scores of the TE group also improved from 114.9 at pre-test to 116.9 after training.Conclusion: Findings from this prospective study demonstrated that low-intensity level mind-body exercise could be beneficial to the cognitive functioning of older adults.Keywords: coordination exercise, cognitive function, elderly, Chinese

Like Moon or Mars, Earth experienced one or several deep magma ocean periods of globalextent in a later stage of its accretion. The crystallization of these magma oceans is of keyimportance for the chemical structure of Earth, the mantle evolution and the onset of platetectonics. Due to the fast rotation of early Earth and the small magma viscosity, rotationprobably had a profound effect on differentiation processes. For example, Matyska et al. propose that the distribution of heterogeneities like the two large low shear velocityprovinces (LLSVP) at the core mantle boundary is influenced by rotational dynamicsof early Earth. Further Garnero and McNamara  suggest that the LLSVPs arevery long-living anomalies, probably reaching back to the time of differentiation andsolidification of Earth. However, nearly all previous studies neglect the effects of rotation.In our previous work using a Cartesian model, a strong influence of rotation as well asof latitude on the differentiation processes in an early magma ocean was revealed. Weshowed that crystal settling in an early stage of magma ocean crystallization cruciallydepends on latitude as well as on rotational strength and crystal density.In order to overcome the restrictions as to the geometry of the Cartesian model, we arecurrently developing a spherical model to simulate crystal settling in a rotating sphericalshell. This model will allow us not only to investigate crystal settling at the poles andthe equator, but also at latitudes in-between these regions, as well as the migration ofcrystals between poles and equator.

The depth-dependence of the viscosity is not well constrained by observations alone. Non-monotonic viscosity profiles have been often proposed in the past and are in the range of possible solutions. Such viscosity structures find new vigor on the light of recent discoveries of iron-spin transition in mantle minerals and their consequences on seismic interpretation  and dynamical evolution of the mantle. Using the recently introduced Multipole-Accelerated Boundary Element Method, we study the entire space of possible models of plumes and slabs crossing a broad region where mantle viscosity and/or density are non-monotonic . The viscosity peak considered are 1, to 100 times then the rest of the mantle, while the density step considered is 0 to 2% different from the adiabatic profile. We identify the critical viscosity and density profiles that produce stalling or penetration of slabs and the continuous or intermittent penetration of plumes through the mid lower mantle. Based on our results, we envisage possible dynamic scenarios that would separate the mantle in two regions,suggesting a long term bifurcation originating, probably, from the spin transition itself.

This review is to update the current findings on non-pharmacological, pharmacological, and modality strategies to manage fatigue in patients with SLE and to provide some recommendations on optimal management of fatigue based on the best available evidence. We performed a systematic literature search of the PubMed and Scopus databases to identify publications on fatigue management in patients with SLE. Based on the studies reported in the literature, we identified nine intervention strategies that have the potential to alleviate fatigue in patients with SLE. Of the nine strategies, aerobic exercise and belimumab seem to have the strongest evidence of treatment efficacy. N-acetylcysteine and ultraviolet-A1 phototherapy demonstrated low-to-moderate levels of evidence. Psychosocial interventions, dietary manipulation (low calorie or glycemic index diet aiming for weight loss, vitamin D supplementation, and acupuncture all had weak evidence. Dehydroepiandrosterone is not recommended due to a lack of evidence for its efficacy. In addition to taking treatment efficacy and side effects into consideration, clinicians should consider factors such as cost of treatment, commitments, and burden to the patient when selecting fatigue management strategies for patients with SLE. Any comorbidities, such as psychological distress, chronic pain, sleep disturbance, obesity, or hypovitaminosis D, associated with fatigue should be addressed.

The cytotoxic effects as well as the in vitro efficacy in regulation of inflammatory responses by free-form piroxicam and liposome-encapsulated piroxicam were evaluated using a lipopolysaccharide-sensitive macrophage cell line, RAW 264.7.Results: Cells treated with liposome-encapsulated piroxicam demonstrated higher cell viabilities than those treated with free-form piroxicam. In addition, the liposomal piroxicam formulation resulted in statistically stronger inhibition of pro-inflammatory mediators (ie, nitric oxide, tumor necrosis factor-α, interleukin-1β, and prostaglandin E2 than piroxicam at an equivalent dose. The liposome-encapsulated piroxicam also caused statistically significant production of interleukin-10, an anti-inflammatory cytokine.Conclusion: This study affirms the potential of a liposomal piroxicam formulation in reducing cytotoxicity and enhancing anti-inflammatory responses in vitro.Keywords: liposomes, nitric oxide, cytokines, prostaglandin E2, interleukin-1β, piroxicam

Furthermore, we constrain the exhumation history of the mountain belt using zircon (U-Th-Sm)/He dating. Geodynamic and exhumation events can be linked to structural generations. This results in a new tectonic model of the Oman Mountains. We find a remarkable along-strike consistency of mountain building phases and argue involvement of a micro-plate is not required.

The current study set out to show that visual stimulus awareness plays a crucial role in determining whether vicarious pain primarily activates behavioral defense systems that enhance pain sensitivity and stimulate withdrawal or appetitive systems that attenuate pain sensitivity and stimulate approach. We employed a mixed factorial design with the between-subject factors exposure time (subliminal vs optimal and vicarious pain (pain vs no pain images, and the within-subject factor session (baseline vs trial to investigate how visual awareness of vicarious pain images affects subsequent self-pain in the cold-pressor test. Self-pain tolerance, intensity and unpleasantness were evaluated in a sample of 77 healthy participants. Results revealed significant interactions of exposure time and vicarious pain in all three dependent measures. In the presence of visual awareness (optimal condition, vicarious pain compared to no-pain elicited overall enhanced self-pain sensitivity, indexed by reduced pain tolerance and enhanced ratings of pain intensity and unpleasantness. Conversely, in the absence of visual awareness (subliminal condition, vicarious pain evoked decreased self-pain intensity and unpleasantness while pain tolerance remained unaffected. These

Few outlets were able to accommodate and quickly share that amount of information as well as the Internet. To honor the 10-year anniversary of the launch of Terra, we would like to highlight the education and outreach efforts of the Terra mission on the Internet and its reach to the science attentive public. The Internet or web has been the primary way of delivering Terra content to different groups- from formal and informal education to general public outreach. Through the years, many different web-based projects have been developed, and they were of service to a growing population of the science attentive public. One of Terra’s original EPO activities was the Earth Observatory. It was initially dedicated to telling the remote sensing story of Terra, but quickly grew to include science and imagery from other sensors. The web site allowed for collaboration across NASA centers, universities and other organizations by exchanging and sharing of story ideas, news and images. The award winning Earth Observatory helped pave the way for the more recently funded development of the Climate Change website. With its specific focus on climate change studies, once again, Terra stories and images are shared with an even more specific audience base. During the last 10 years, Terra as a mission has captured the imagination of the public through its visually stunning and artistically arresting images. With its five instruments of complementary but unique capabilities, the mission gave the world not just pretty pictures, but scientific data-based images. The world was able to see from space everything from calving icebergs to volcanic eruption plumes and the eye of a

Active margins are important sites of new continental crust formation by magmatic processes related to the subduction of oceanic plates. We investigate these phenomena using a three-dimensional coupled petrological-geochemical-thermomechanical numerical model, which combines a finite-difference flow solver with a non-diffusive marker-in-cell technique for advection (I3ELVIS code, Gerya and Yuen, PEPI,2007). The model includes mantle flow associated with the subducting plate, water release from the slab, fluid propagation that triggers partial melting at the slab surface, melt extraction and the resulting volcanic crustal growth at the surface. The model also accounts for variations in physical properties (mainly density and viscosity) of both fluids and rocks as a function of local conditions in temperature, pressure, deformation, nature of the rocks, and chemical exchanges. Our results show different patterns of crustal growth and surface topography, which are comparable to nature, during subduction at active continental margins. Often, two trench-parallel lines of magmatic activity, which reflect two maxima of melt production atop the slab, are formed on the surface. The melt extraction rate controls the patterns of new crust at different ages. Moving free water reflects the path of fluids, and the velocity of free water shows the trend of two parallel lines of magmatic activity. The formation of new crust in particular time intervals is distributed in finger-like shapes, corresponding to finger-like and ridge-like cold plumes developed atop the subducting slabs (Zhu et al., G-cubed,2009; PEPI,2011). Most of the new crust is basaltic, formed from peridotitic mantle. Granitic crust extracted from melted sediment and upper crust forms in a line closer to the trench, and its distribution reflects the finger-like cold plumes. Dacitic crust extracted from the melted lower crust forms in a line farther away from the trench, and its distribution is anticorrelated with

horizontal shaking our model predicts that the soil remains rigid. Under stronger accelerations, some of the particles, which constitute the medium, slide past each other, and the medium slowly rearranges. Yet, in this regime of shaking, the shaking is insufficient to cause the building to slide. The building sinks simply due to hydrostatic considerations, and since it is a static object in a dynamically rearranging medium. This is the case we call liquefaction. Eventually, for even stronger accelerations, both the particles and the building can slide and we predict convective movement. To test this model we run numerical simulations (granular dynamics DEM algorithm) and laboratory experiments. The numerical experiments do not include pore pressure, and only simulate buoyancy effects of water. The controlling parameters are the amplitude and frequency of the shaking, and the water level. With a saturated medium, experiments and simulations display three different behaviors: rigid, liquefaction, and convection, in agreement with our theoretical model. The peak ground acceleration (PGA) is the decisive parameter. It is important to note that for dry media and for a case when the building is fully submerged underwater, both in experiments and in simulations, the liquefaction effect disappears. Based on our work we suggest that elevated pore pressure conditions are not necessary for inducing liquefaction, and that liquefaction can occur under well drained and highly compacted soils, in situations previously considered to be safe from liquefaction.

Furthermore, ASCO scores were unable to discriminate between drugs providing the most and least value. The evaluation provides specific areas of weakness that can be addressed in future updates of the ASCO framework to improve usability. Meanwhile, the UCSF Medical Center should rely on CEAs, which are highly accessible for the highlighted cancer drugs. The MOC role can include summarizing and disseminating available CEA studies for interpretation by clinicians and financial counselors around drug value.

Using Scientific Thinking and Intelligent Aggregation to Tame Big Data. Dave Yuen, Department of Minnesota Supercomputing Institute , University of Minnesota, Minneapolis, MN 55455-0219 USA Richard Strelitz, CCS-3, MS B265, Los Alamos National Laboratory Los Alamos, NM 87545 We take the contrarian position that BIG DATA is at best a misnomer. The average human is confronted with Terabytes to Petabytes of sensor data daily, not to mention all of the internally generate throughts and conclusions. We start with the assumption that the coping mechanism is based on aggregation, suppression and prediction in a tight, Kalman filter based feedback system. Over the past year we have been developing tools and schemas that implement if not the mechanisms then the concepts we use every day, at work and in life. Current simulation science and its most faithful henchmen-visualization and statistics, are predicated on the idea that value at a point (on a grid) is the natural if not only was to consider data. It gives primacy to the geometry, itself an artifact of computational ease and also creates an entirely misleading sense that the value is precise and immutable. Yet when we view the same representation through our scientific lenses, we see patterns, structures, and familiar forms, and most often a large number of these in various sizes, orientations and stages of maturity. It is the pattern that matters. We have applied this concept to ocean eddy's that make up a significant part of the world wide ocean. Many ';see' the eddies, but few have attempted to compile demographics of size, age, depth, power that speak powerfully to the degree of mixing of various source waters. Fewer still have used this catalogue of self-similar features to develop scaling laws that relate to their formation and disappearance. Here we introduce the essential paradigm of the scientific method --observe, simulate, refine, repeat. A key feature of our approach is its adherence to first principles and

at less than 700°C (e.g. Jackson 02). We build on earlier studies (LePichon et al 92, 97; Schulte-Pelkum et al 05; Monsalve et al 08) to develop the hypothesis that there is rapid growth of garnet at 80 km and 1000°C within subducting Indian crust, causing increased rock densities. Dense eclogites founder into the mantle, while relatively buoyant lithologies accumulate in thickening lower crust. Mantle return flow plus radioactive heating in thick, felsic crust maintains high temperature, facilitating formation of hybrid magmas and pyroxenites. The crustal volume grows at 760 cubic m/yr/m of strike length. Moho-depth earthquakes may be due to localized deformation and thermal runaway in weak layers and along the margins of dense, foundering diapirs (e.g., Larsen & Yuen 97; Braeck & Podladchikov 07; Kelemen & Hirth 07; Lister et al 08; Kufner et al 16). A similar process may take place at some convergent margins, where forearc crust is thrust beneath hot, magmatic arc crust, leading to extensive, Moho-depth density sorting and hybrid crust-mantle magmatism in Arc Tadpole Zones.

significantly predicted intentions to use self-help (95% CI 2.08-16.24) and therapist-assisted (95% CI 1.71-11.90) online services in future. Being older predicted increased intentions to use therapist-assisted online services in future (95% CI 1.01-1.06), as did more confidence using computers and the Internet (95% CI 1.06-2.69). Technology confidence was also found to predict greater preference for online services versus face-to-face options (95% CI 1.24-4.82), whereas higher doctor-related locus of control, or LOC (95% CI 0.76-0.95), and extraversion (95% CI 0.88-1.00) were predictive of lower likelihood of preferring online services relative to face-to-face services. Despite generally low reported preferences toward e-mental health services, intentions to access these services are higher, raising the question of how to best encourage translation of intentions into behavior (ie, actual use of programs). Strategies designed to ease people into new Internet-based mental health programs (to enhance confidence and familiarity) may be important for increasing the likelihood that they will return to such programs later. ©Sonja March, Jamin Day, Gabrielle Ritchie, Arlen Rowe, Jeffrey Gough, Tanya Hall, Chin Yan Jackie Yuen, Caroline Leanne Donovan, Michael Ireland.

Mesocriconemaantipolitanum are a little bit described. Helicotylenchus vulgaris, initially worldwide was reported by Yuen in 1964 and for the first time from Iran in 1995 was reported by KargarBideh, and his collaborators from Hamdan province. The species from morphological and morphometrical characteristic point of view is very close to Helicotylenchusminzi.Mesocriconemaantipolitanum firstly in 1991 was reported from Iran by Loof and Barooti from apple, wheat and lucerne roots from Karaj, potato from Lorestan, lucerne from Zanjanand apricot from Northern Azarbaijan. In the research, the species was isolated from Piranshahr, Miyandoab, Bookan and Mahabad vineyard cities of Western Azarbaijan. The species is very similar to M. surinamense. Conclusion: Nine species including Discotylenchusdiscretus, Ditylenchusacutus, Ditylenchusacutus, Paratylenchuslabiosus, Pratylenchoidesvariabilis, Pratylenchuscoffeae, Pratylenchuspenetrans, Pratylenchusscribneri, Pratylenchussefaensisand Scutylenchuspaniculoides were recorded for the first time from the rhizosphere of grapevine from Iran. Considering thatall the nematodes are already recorded from Iran, herein only the dominant species are described.
