The Study of Rapeseed Characteristics by Factor Analysis under Normal and Drought Stress Conditions

To understand internal characteristics relationships and determine factors which explain under consideration characteristics in rapeseed varieties, 10 rapeseed genotypes were implemented in complete accidental plot with three-time repetitions under drought stress in 2009-2010 in research field of agriculture college, Islamic Azad University, Karaj branch. In this research, 11 characteristics include of characteristics related to growth, production and functions stages was considered. Variance analysis results showed that there is a significant difference among rapeseed varieties characteristics. By calculating simple correlation coefficient under both conditions, normal and drought stress indicate that seed function characteristics in plant and pod number have positive and significant correlation in 1% probable level with seed function and selection on the base of these characteristics was effective for improving this function. Under normal and drought stress, analyzing the main factors showed that numbers of factors which have more than one amount, had five factors under normal conditions which were 82.72% of total variance totally, but under drought stress four factors diagnosed which were 76.78% of total variance. By considering total results of this research and by assessing effective characteristics for factor analysis and selecting different components of these characteristics, they can be used for modifying works to select applicable and tolerant genotypes in drought stress conditions. Keywords—Correlation, drought stress, factor analysis, rapeseed.
Differential response of communities of plants, snails, ants and spiders to long-term mowing in a small-scale experiment

We examined the response of communities of four groups of organisms (plants, snails, ants and spiders) in a small scale mosaic of 8-years mown and unmown plots in a wet meadow in Central Europe. The experimental setup consisted of 7 unmown and 8 regularly mown 4 m2 plots in checkerboard arrangement. Eight years after the start of the experiment, the plant community structure diverged in response to mowing/nonmowing, both in species composition and structure. Both bryophyte and vascular plant species numbers were significantly higher in the mown plots. In unmown plots, bryophytes nearly disappeared and plots were dominated by the tall tussock grass Molinia caerulea. Both diversity and abundance of snails were higher in unmown plots than in mown ones. Ant nests were more abundant in mown plots and species composition differed between mown and unmown plots. We captured significantly more individuals of spiders in mown plots but we did not find any difference in species composition. We conclude that the 8-years duration of different management of 4 m2 plots was sufficient to establish different communities in low movable organisms, whereas these plots are probably too small to host different assemblages of organisms with good active dispersal abilities.
Investigation of ka-band satellite communication propagation in equatorial regions

Future satellite communication (SatCom) systems operating at high frequencies (Ka-band and above) are expected to suffer from deep signal fades due to rain, particularly in tropical/equatorial regions. Accurate satellite propagation channel modeling requires the knowledge of radio channel characteristics with respect to the peculiarities of tropical precipitation. The European Space Agency (ESA) has recently funded a Ka-band propagation measurement campaign over Peninsular Malaysia that exploits the Syracuse-3A satellite (beacon frequency 20.245 GHz). The main objective of this campaign is to collect actual propagation Ka-band signal measurements in a heavy rain region with the aim of assessing and improving currently available statistical models of rain fade dynamic as well as evaluating the performance of site diversity and time diversity techniques. Some results relative to first- (i.e. cumulative distribution function of attenuation) and second-order (i.e. fade duration and fade slope) statistics of rain attenuation are reported based on the basis of the simulation using weather radar data, the prediction of the Stratiform convective- Synthetic Storm Technique (SC-SST) model, ITU-R recommendation and comparison of measured statistics from the literature. The discrepancy among the predicted results implies that it is important to validate the accuracy of current radio channel prediction models using actual experimental data. The experimental results of this campaign will eventually be submitted to the International Telecommunication Union-Radiocommunication Sector (ITU-R) for the benefit of the scientific community, specifically in heavy rain regions.
Some Properties of Correlations of Quantum Lattice Systems in Thermal Equilibrium

Simple proofs of uniqueness of the thermodynamic limit of KMS states and of the decay of equilibrium correlations are presented for a large class of quantum lattice systems at high temperatures. New quantum correlation inequalities for general Heisenberg models are described. Finally, a simplified derivation of a general result on power-law decay of correlations in 2D quantum lattice systems with continuous symmetries is given, extending results of McBryan and Spencer for the 2D classical XY model.
EFFECT OF EXTRACTIVES ON THE THERMAL DECOMPOSITION OF WHEAT, TRITICALE, AND FLAX CROP RESIDUES : A KINETIC STUDY

A kinetic study was performed using the Kissinger and Coats-Redfern methods to examine the effect of extractives on thermal decomposition of three crop residues, wheat straw, triticale straw and flax shives. The extractives-free crop residues required higher temperatures for the onset of thermal decomposition than the corresponding native/unextracted samples. Activation energy (Ea) values varied according to kinetic analysis and the extractives-free samples generally showed significantly higher Ea values (65-214 kJ.mol-1) than the native/unextracted samples (58-205 kJ.mol-1). This information is necessary for defining the use of crop residues as agro-fillers in composite materials and feedstock for bioenergy and biochemical via pyrolysis. Keywords: wheat straw, triticale straw, flax shives, extractives, thermal decomposition, kinetic analysis, Kissinger method, Coats-Redfern method, activation energy.
ON ASYMMETRY, HOLIDAY AND DAY-OF-THE-WEEK EFFECTS IN VOLATILITY OF DAILY STOCK RETURNS : THE CASE OF JAPAN

In this paper, we investigate volatility in Japanese stock returns, using the state space model. The daily data of Nikkei 225 stock average from January 4, 1985 to June 10, 2004 are utilized and the stochastic volatility model is assumed for the noise component. We examine whether there are asymmetry, holiday and day-of-the-week effects in volatility. Moreover, we see whether U.S. stock price change influences the volatility in Japanese stock price, which is called U.S. stock price change effect in this paper (note that this is the asymmetry effect caused by U.S. stock market). It is also examined whether we have volatility transmission from U.S. to Japan. As a result, we empirically find that the asymmetry, holiday, U.S. stock price volatility transmission and Tuesday effects strongly influence the volatility in Japanese stock returns. Moreover, it is shown that both volatility and level in Japanese stock returns depend on U.S. stock returns.
Identifying the Effects of Monetary Policy Shock on Output and Prices in Thailand

This paper attempts to identify the effects of monetary policy shock on output and price level in Thailand during 2005Q1 and 2016Q2. Recently available policy rate is used as a monetary policy variable. The structural VAR methodology is employed to identify the monetary policy shock. To enhance the precision of the model specification, the short-run restrictions are imposed on the specified structural model of cointegrated variables to allow the levels of variables to interact simultaneously with each other. The results from the analysis of the structural model reveal that a shock to monetary policy drives cycles for both real GDP and the inflation rate.
Verification of a Predictive Model of Psychological Health at Work in Canada and France

The purpose of this study was to test the invariance of a predictive model of psychological health at work (PHW) in Canada and France. The model a) defines PHW as an integrative second-order variable (low distress, high well-being) and b) includes three categories of PHW inductors (job demands, personal resources and social-organizational resources) and one psychological intermediate variable (needs satisfaction) that were found to be directly or indirectly related to PHW in a previous study on a sample of French teachers (Boudrias, Desrumaux, Gaudreau, Nelson, Savoie and Brunet, 2011). To test if this model is invariant across countries, these data from French teachers ( N = 391) were reanalyzed and compared with data from a sample of Canadian teachers ( N = 480) who completed the same set of questionnaires. Results from structural equation modeling analyses indicated that the model is completely invariant across the two samples. Therefore, pathways to PHW appeared to generalize across these samples of teachers without the addition of other cultural variables. This PHW model suggests that personal resources exert considerable influence directly and indirectly on psychological health through multiple mediators. Research implications and study limitations are discussed.
Computation of extended symmetry groups for multidimensional subshifts with hierarchical structure

Automorphism groups are intrincate conjugacy invariants for subshifts, which can reveal important features of the dynamical structure of a shift action. One important case is the study of automorphism groups when the underlying subshift has a very rigid structure, e.g. substitutive subshifts or aperiodic constructions with large-scale self-similarity, such as the Robinson shift. In this work we study the automorphism group of bijective substitutive subshifts, and a potential generalization in the form of the group of extended symmetries, studied previously by Michael Baake, John Roberts and Reem Yassawi (arXiv:1611.05756); these symmetries, by allowing for shearing and other deformations of the underlying group, may reveal additional information of a geometric nature about the structure of these subshifts.
Interim Progress Report for CDFA Agreement Number 17-0514-000-SA: "GENOME EDITING OF TAS4, MIR828 AND TARGETS MYBA6/A7: A CRITICAL TEST OF XYLELLA FASTIDIOSA INFECTION AND SPREADING MECHANISMS IN PIERCE’S DISEASE" Principal Investigator (PI):

INTRODUCTION This report covers experiments in progress and completed since the last report published in the biennial Proceedings (2018; https://www.cdfa.ca.gov/pdcp/research.html), but the short-term nature of funding cycles and attendant line-item reports can obscure the big picture. Our charge as researchers is to delivery practical and timely solutions to stakeholders. Yet we still do not know the underlying mechanisms of host resistance to PD, the roles nutrients play in disease states, the nature of pleiotropic PD symptoms like leaf scorch, shriveling berries, matchstick petioles, cane bark islands, or effects on root physiology (Fig. 1). If we can gain insights into the mechanisms we will understand the etiology of PD and perhaps be able leverage knowledge and develop cogent strategies to engineer host tolerance. The threat of another PD epidemic like in southern California in the 1880s and again in 1990s remains real. Look to southern Italy where olive quick decline syndrome is decimating centuries-old olive groves to appreciate the risk. As a translational researcher new to the problem it is humbling to read Pierce's 1892 monograph. Here quoted the first sentences which frame the issue faced yet today: "The vine interests of California are of greater national than local importance. Locally nearly all horticultural interests are large, and the State, though deriving a liberal return from the grape, is not dependent upon it. On the other hand, the entire country is at present almost wholly dependent on California for domestic raisins and wines of the better class. The future will hardly change these relations. Should some disease destroy the grape crop of California every State in the Union would be forced to send money to foreign countries for raisins and fine brands of wine. too much cannot be done to guard and stimulate the industry.

Customer Loyalty to Content-Based Web Sites: The Case of an Online Health Care Service

Past e‐service research has largely concentrated on customer responses to online retailers. The present study sheds light on the determinants of customer loyalty to a content‐based service, a healthcare Web site. Content‐based service providers must build a loyal customer base in order to attract advertisers and sponsors. Lack of trust has been one of the most important reasons for consumers not adopting online services involving financial exchanges, but trust appears to be equally important to exchanges that require divulging sensitive information, such as health issues. Results reveal that loyalty to the health site is satisfaction‐driven, but that trust is the main antecedent of satisfaction. Need fulfilment, responsiveness, security and technical functionality of the Web site are shown to influence trust. Managerial implications are provided.
On a comparison method to reaction-diffusion systems and its applications to chemotaxis

In this paper we consider a general system of reaction-diffusion equations and introduce a comparison method to obtain qualitative properties of its solutions. The comparison method is applied to study the stability of homogeneous steady states and the asymptotic behavior of the solutions of different systems with a chemotactic term. The theoretical results obtained are slightly modified to be applied to the problems where the systems are coupled in the differentiated terms and / or contain nonlocal terms. We obtain results concerning the global stability of the steady states by comparison with solutions of Ordinary Differential Equations.
Measurements of the separated longitudinal structure function FL from hydrogen and deuterium targets at low Q2

Structure functions, as measured in lepton-nucleon scattering, have proven to be very useful in studying the partonic dynamics within the nucleon. However, it is experimentally difficult to separately determine the longitudinal and transverse structure functions, and consequently there are substantially less data available in particular for the longitudinal structure function. Here, we present separated structure functions for hydrogen and deuterium at low four-momentum transfer squared, Q^2 < 1 GeV^2, and compare them with parton distribution parametrization and k_T factorization approaches. While differences are found, the parametrizations generally agree with the data, even at the very low-Q^2 scale of the data. The deuterium data show a smaller longitudinal structure function and a smaller ratio of longitudinal to transverse cross section, R, than the proton. This suggests either an unexpected difference in R for the proton and the neutron or a suppression of the gluonic distribution in nuclei.
Structural Change Tests in Tail Behaviour and the Asian Crisis

This paper explores tests of the hypothesis that the tail thickness of a distribution is constant over time. Using Hill's conditional maximum likelihood estimator for the tail index of a distribution, tests of tail shape constancy are constructed that allow for an unknown breakpoint. The recursive test is shown to be inconsistent in one direction, and only a one-sided test is recommended. Specifically, the test can be used when the alternative hypothesis is that the tail index decreases over time. A rolling and sequential version of the test is consistent in both directions. The methods are illustrated on recent stock price data for Thailand, Malaysia and Indonesia. The period covers the recent Asian financial crisis and enables us to assess whether breakpoints in domestic asset return distributions are related to known changes in institutional arrangements in the foreign currency markets of these countries.
Object-Feature Binding Survives Dynamic Shifts of Spatial Attention

Visual object perception requires integration of multiple features; spatial attention is thought to be critical to this binding. But attention is rarely static—how does dynamic attention impact object integrity? Here, we manipulated covert spatial attention and had participants (total N = 48) reproduce multiple properties (color, orientation, location) of a target item. Object-feature binding was assessed by applying probabilistic models to the joint distribution of feature errors: Feature reports for the same object could be correlated (and thus bound together) or independent. We found that splitting attention across multiple locations degrades object integrity, whereas rapid shifts of spatial attention maintain bound objects. Moreover, we document a novel attentional phenomenon, wherein participants exhibit unintentional fluctuations—lapses of spatial attention—yet nevertheless preserve object integrity at the wrong location. These findings emphasize the importance of a single focus of spatial attention for object-feature binding, even when that focus is dynamically moving across the visual field.
A convergent and universally bounded interpolation scheme for the treatment of advection

A high resolution scheme with improved iterative convergence properties was devised by incorporating total‐variation diminishing constraints, appropriate for unsteady problems, into an implicit time‐marching method used for steady flow problems. The new scheme, referred to as Convergent and Universally Bounded Interpolation Scheme for the Treatment of Advection (CUBISTA), has similar accuracy to the well‐known SMART scheme, both being formally third‐order accurate on uniform meshes for smooth flows. Three demonstration problems are considered: (1) advection of three scalar profiles, a step, a sine‐squared, and a semi‐ellipse; (2) Newtonian flow over a backward‐facing step; and (3) viscoelastic flow through a planar contraction and around a cylinder. For the case of the viscoelastic flows, in which the high resolution schemes are also used to represent the advective terms in the constitutive equation, it is shown that only the new scheme is able to provide a converged solution to the prescribed tolerance.

The effect of plant growth-promoting rhizobacteria on yield, water use efficiency and Brix Degree of processing tomato

Open field experiments were conducted to investigate the effects of plant growth-promoting rhizobacteria (PGPR) (Phylazonit MC®) as a biofertilizer on processing tomato cultivar var. Uno Rosso F1, grown under three different regimes of water supply. Field effectiveness of rhizobacteria inoculation on total biomass production, yield and water use efficiency, were examined in 2015 and 2016. Seedlings were inoculated with 1% liquid solution of Phylazonit MC® (Pseudomonas putida, Azotobacter chroococcum, Bacillus circulans, B. megaterium; colony-forming unit: 109 CFU/mL) at sowing and planting out by irrigation. There were three different regimes of water supply: rain-fed control (RF); deficit water supply (WS50) and optimum water supply (WS100); the latter was supplied according to the daily evapotranspiration by drip irrigation. Total aboveground biomass (shoot and total yield) and red fruits yield were measured at harvest in August, in both years. Total biomass changed between 32.5 t/ha and 165.7 t/ha, the marketable yield from 14.7 t/ha to 119.8 t/ha and water use efficiency (WUE) between 18.5 kg/m3 to 32.0 kg/m3. The average soluble solids content of the treatment combinations ranged from 3.0 to 8.4°Brix. Seasonal effects were significant between the two years with different precipitation, which manifested in total biomass and marketable yield production. PGPR increased WUE only in WS50 in both years, while under drought stress and higher water supply, the effect was not clear. The effect of PGPR treatment on marketable yield, total biomass and WUE was positive in both years when deficit irrigation was applied and only in the drier season in the case of optimum water supply.
1 Behavior Revealed in Mobile Phone Usage Predicts Credit Repayment

Many households in developing countries lack formal financial histories, making it difficult for firms to extend credit, and for potential borrowers to receive it. However, many of these households have mobile phones, which generate rich data about behavior. This paper shows that behavioral signatures in mobile phone data predict default, using call records matched to repayment outcomes for credit extended by a South American telecom. On a sample of individuals with (thin) financial histories, our method actually outperforms models using credit bureau information, both within time and when tested on a different time period. But our method also attains similar performance on those without financial histories, who cannot be scored using traditional methods. Individuals in the highest quintile of risk by our measure are 2.8 times more likely to default than those in the lowest quintile. The method forms the basis for new forms of credit that reach the unbanked. This draft: October 21, 2018. First draft: January 6, 2015.

UvA-DARE ( Digital Academic Repository ) New instability of non-extremal black holes : spitting out supertubes

We search for stable bound states of non-extremal rotating three-charge black holes in five dimensions (Cvetic-Youm black holes) and supertubes. We do this by studying the potential of supertube probes in the non-extremal black hole background and find that generically the marginally bound state of the supersymmetric limit becomes metastable and disappears with non-extremality (higher temperature). However near extremality there is a range of parameters allowing for stable bound states, which have lower energy than the supertube-black hole merger. Angular momentum is crucial for this effect. We use this setup in the D1-D5 decoupling limit to map a thermodynamic instability of the CFT (a new phase which is entropically dominant over the black hole phase) to a tunneling instability of the black hole towards the supertube-black hole bound state. This generalizes the results of [1], which mapped an entropy enigma in the bulk to the dual CFT in a supersymmetric setup.
