Preserving Rice Quality: Fine-Mapping and Introgressing a Fissure Resistance Locus

Rice (Oryza sativa L.) kernel fissuring is a major concern of both rice producers and millers. Fissures are small cracks in rice kernels that increase breakage of kernels when milled, and decrease the value of processed rice. This study employed molecular gene tagging methods to fine-map a fissure resistance (FR) locus found in ‘Cybonnet’, a semidwarf tropical japonica cultivar, as well as transfer this trait to rice genotypes of taller, non-semidwarf plant height that are better adapted to some rice production systems. Three QTLs for FR were previously reported; the FR locus with strongest effect resides near the semidwarf sd-1 locus on the long arm of chromosome 1, explaining associations observed between increased FR and reduced plant height. This study began with F2 progeny from a cross between a U.S. inbred breeding line with non-semidwarf (Sd-1/Sd-1) plant height and poor milling yields, and Cybonnet, which is semidwarf (sd-1/sd-1) and noted for having improved milling quality due to increased FR. Simple sequence repeat (SSR) molecular markers were used to select 11 F2 progeny plants that retained at least one copy of the Sd-1 allele, but also contained evidence of genetic recombination in the region of chromosome 1, known to contain Sd-1 and qFIS1-2, so that the positon of qFIS1-2 relative to Sd-1 could be determined more precisely, and so that FR allele could be recombined with the Sd-1 allele. Three of the 11 selected plants were also homozygous at the two known FR QTLs that are not closely linked to sd-1; another four plants were homozygous at one but not both of the two additional FR loci. The F2:3 progeny generated were genotyped prior to being phenotyped; only individuals homozygous for the new recombination underwent extensive evaluation for FR. Progeny from three of 11 populations have been phenotyped. Marker-trait linkages observed in the first two populations indicated that qFIS1-2 resides distal to RM1068. Research efforts were then focused on just those populations whose recombination points were distal to RM1068 (i.e., at a base pair location higher 1:38439184). Results from the three populations observed to date indicate that the qFIS1-2 locus resides distal to RM1068 at 1:38439184 but anterior to RM3482 at 1:39720039, or approximately 6 to 10 cM distal to sd-1 on chromosome 1. The recombination documented in this study verifies that the previously identified qFIS1-2 is linked to, but not pleiotropic with, sd1 and thus can be recombined with Sd-1 during introgression breeding to increase the FR of rice cultivars having non-semidwarf stature.
arXiv : Production of extra quarks decaying to Dark Matter beyond the Narrow Width Approximation at the LHC

This paper explores the effects of finite width in processes of pair production of an extra heavy quark with charge 2/3 (top partner) and its subsequent decay into a bosonic Dark Matter (DM) candidate -- either scalar or vector -- and SM up-type quarks at the Large Hadron Collider (LHC). This dynamics has been ignored so far in standard experimental searches of heavy quarks decaying to DM and we assess herein the regions of validity of current approaches, based on the assumption that the extra quarks have a narrow width. Further, we discuss the configurations of masses, widths and couplings where the latter breaks down.
A pr 2 01 6 Symplectic non-squeezing in Hilbert space and discrete Schrödinger equations

We prove a generalization of Gromov’s symplectic non-squeezing theorem for the case of Hilbert spaces. Our approach is based on filling almost complex Hilbert spaces by complex discs partially extending Gromov’s results on existence of J-complex curves. We apply our result to the flow of the discrete nonlinear Schrödinger equation. MSC: 32H02, 53C15.
Sliding, slipping and rolling: the sedimentation of a viscous drop down a gently inclined plane

We consider the steady sedimentation under gravity of a viscous drop, suspended in a viscous liquid, along a plane tilted at a small angle $\alpha$ to the horizontal. The drop does not wet the wall but is supported by a thin lubricating film of liquid. In the Stokes-flow limit, the problem is parameterized by $\alpha$, the ratio $B$ of buoyancy to capillary forces (a Bond number) and a viscosity ratio $\lambda$. Provided $B$ is not too large ($B\,{\ll}\,\alpha^{-1}$ in two dimensions, $B\,{\ll}\,\alpha^{-4/3}$ in three dimensions), the drop's motion can be described asymptotically by combining a capillary-statics approximation for the drop shape away from the wall, lubrication theory for the thin film and a combination of lubrication theory and a half-plane boundary-integral method for the drop interior. Systematic scaling arguments for both two- and three-dimensional drops, supported by detailed calculations, are used to survey $(B,\lambda)$-parameter space for fixed $\alpha\,{\ll}\,1$. We find a strong coupling between drop shape (ranging from nearly round to a flattened pancake), kinematics (including slipping, sliding, rolling and tank-treading motions) and the site of dominant viscous dissipation (the edges of the thin film, the bulk of the thin film or the drop interior). Predictions of drop speed and shape are compared with available experimental and computational data.
Robots Conquering the Homeland of the Vikings 1

The movement of robots from the production line to the service sector provides a potential radical solution to innovate and transform public service delivery. Although robots increasingly are adopted in public service delivery (e.g., in healthcare and eldercare) as a complementary and in some cases substitution for traditional labor intensive services, little is known about their impact on organizations work processes, and how key stakeholders react toward robots. This paper argues that the public administration research community needs to address the surfacing robots and how and to what extent the robots are energizing changes in public service delivery. On this backdrop, this single case study investigates implementation and use of robot vacuum cleaners in Danish eldercare at the local government level. Using an extended version of the technological frame concept, this paper illustrates how technologist, managers, frontline staff and clients have different perceptions towards robot vacuum cleaning. The technologist and managers praise the new innovation for facilitating savings on the current accounts. By contrast, the frontline staff and clients find that robots do not sufficiently clean the floors. Our account reveals how the social construction of robot technology did not end once designed and developed, but rather continued during its use as different actors constructed different interpretations of the robots based on their interactions with them. 1 An earlier version of this paper was presented at the Annual European Group of Public Administration (EGPA) Conference (Permanent Study Group I: E-Government (ICT in PA), Edinburgh (Scotland, UK), 11-13 September 2013. We are thankful for the comments from the reviewers and during the discussion at the conference. Also, we are in debt to our colleagues at the Center for Management, Organization, and Administration (COMA) at Aalborg University.
Comparing the magnetically active young star V889 Herculis to the Sun

This Master’s Thesis deals with stellar magnetic activity, both as it is seen in the Sun, our closest star, and in other, more extreme examples of stellar activity. For the Sun, much higher quality data is available, and for a much longer time, so it remains by far the best studied star, although stars, that are much more magnetically active, have been discovered. This thesis will review the most common forms of magnetic activity, as observed both in the Sun and in other stars. A special focus is given to BY Draconis -type stars. These are young stars, whose photometric brightness variations are caused by large, cool starspots, similar to the sunspots seen on the Sun. A particular BY Draconis -star, V889 Herculis, is analysed in detail, using spectroscopic and photometric methods. From spectroscopy, by the Doppler imaging method, a surface temperature map can be constructed for the star. From photometry, both short-term and long-term variations of the star can be studied. During the 20 years time span of the photometric data, the star seems to have gone through similar activity cycles as the well known 11 year solar cycle. The aim of this thesis is to compare solar and stellar activity in general, and specifically V889 Her to the Sun. Based on the analysis, the basic properties of V889 Her, seen in previous studies, are confirmed: a large polar spot is present on its surface, and there are clear changes in its activity. As the stellar parameters, like mass and surface temperature, of V889 Her are very similar to the Sun, and it is also a single star, the main difference is age. As a young star, V889 Her is still magnetically much more active than the Sun today, but probably it will continue to become more and more similar to the present Sun, losing its high activity with increasing age. Similarly, V889 Her shows us what the Sun most likely was like billions of years ago.
Word-based categorization in 14 to 16 month-old infants: evidence from a Slavic language

We investigate early word-based categorization by testing one sample of infants at the ages of 14 and 16 months using an object manipulation task. Specifically, we investigate the facilitating effect of labeling on: a) categorization of unknown objects with a shared label and a similar shape; b) categorization of unknown objects with a shared label, but no perceptual similarity. The results indicate that an average infant can categorize novel objects with a similar shape and a shared label starting at 16 months of age. Categorization of novel objects with a shared label but no perceptual similarity is at chance level at both ages. These results confirm and extend previous research findings to a new language.
COSMOGRAIL: the COSmological MOnitoring of GRAvItational Lenses VIII. Deconvolution of high resolution near-IR images and simple mass models for 7 gravitationally lensed quasars

Aims. We attempt to place very accurate positional constraints on seven gravitationally lensed quasars currently being monitored by the COSMOGRAIL collaboration, and shape parameters for the light distribution of the lensing galaxy. We attempt to determine simple mass models that reproduce the observed configuration and predict time delays. We finally test, for the quads, whether there is evidence of astrometric perturbations produced by substructures in the lensing galaxy, which may preclude a good fit with the simple models. Methods. We apply the iterative MCS deconvolution method to near-IR HST archival data of seven gravitationally lensed quasars. This deconvolution method allows us to differentiate the contributions of the point sources from those of extended structures such as Einstein rings. This method leads to an accuracy of 1–2 mas in the relative positions of the sources and lens. The limiting factor of the method is the uncertainty in the instrumental geometric distortions. We then compute mass models of the lensing galaxy using state-of-the-art modeling techniques. Results. We determine the relative positions of the lensed images and lens shape parameters of seven lensed quasars: HE 0047-1756, RX J1131-1231, SDSS J1138+0314, SDSS J1155+6346, SDSS J1226-0006, WFI J2026-4536, and HS 2209+1914. The lensed image positions are derived with 1–2 mas accuracy. Isothermal and de Vaucouleurs mass models are calculated for the whole sample. The effect of the lens environment on the lens mass models is taken into account with a shear term. Doubly imaged quasars are equally well fitted by each of these models. A large amount of shear is necessary to reproduce SDSS J1155+6346 and SDSS J1226-006. In the latter case, we identify a nearby galaxy as the dominant source of shear. The quadruply imaged quasar SDSS J1138+0314 is reproduced well by simple lens models, which is not the case for the two other quads, RX J1131-1231 and WFI J2026-4536. This might be the signature of astrometric perturbations caused by massive substructures in the galaxy, which are unaccounted for by the models. Other possible explanations are also presented.
Proposal COSUST Special Issue « Co-designing Research on Social Transformations to Sustainability » Title: The DIALAQ project on sustainable groundwater management: a transdisciplinary and transcultural approachtoparticipatory foresight

Abstract: In the past decades, groundwater over-exploitation has increased the vulnerability of users, social inequalities and environmental degradation. In this context, the DIALAQ project aimed to experiment and disseminate a participatory approach intended to strengthen stakeholders’ capacity to implement more sustainable agricultural and groundwater management. DIALAQ’s network encompasses 8 regions in 4 countries (India, Morocco, France and the United States) including groups of farmers, administration’s representatives, NGOs, elected representatives and researchers from several disciplines. A seed funding enabled cooperation between academics and non-academic partners that led to the consolidation of the network and enabled the design of the project. Firstly, a focused review of literature on participatory foresight exercises in the field of groundwater management is presented. Secondly, the challenges and pathways taken in designing the research is described. This process resulted in a common methodological and ethical framework presented in conclusion.

The Orientations for Learning Mandarin amongst Malay Undergraduate Students

In learning a second or foreign language, motivation has been identified as the learner’s orientation with regard to the goal of learning a second or foreign language. It can be very motivating for students to learn something that is corresponding to their learning orientations. Thus, this study was carried out to investigate the learning orientations of Malay undergraduates who were learning Mandarin as a foreign language. Purposive sampling was used to collect the data. 18 students who enrolled in the Mandarin course in three different levels (elementary, intermediate and advance) during the July 2010 – November 2010 semester were chosen to take part in the study. The students were chosen based on the criteria set by the researcher. The criteria included moderate achievement in Mandarin, aged 20-22, and show good learning attitude. The researcher employed semistructured conversational type of face-to-face interview with the participants. Content analysis was employed to explore information from the transcripts. Fourteen themes of learning orientations were found from the interview data which were subsequently grouped into four major categories: Career-orientated, Enjoyment and Interest, Friendship, and Influence by Others. The study recommends curricula planners to exploit students’ orientations when reviewing the present curriculum for the Mandarin course. In addition, other methods such as survey, educational artefacts, and classroom observation can be employed for future study to gather more information in order to give deeper insights into the investigation and serve for triangulation purposes.
Effect of Farm Income and Off-Farm Wage Variability on Off-Farm Labor Supply

This study models the effects of variability in farm income and off-farm wages on farm operators' labor allocation decisions. A simple theoretical model is employed to develop hypotheses, which are then tested empirically. Variability in farm income and off-farm wages is predicted to have a positive and negative effect, respectively, on off-farm hours worked. The empirical results confirm these predictions.
Environmental R&D

The topic of this note is issues related to R&D expenditures leading to improved technologies for reducing environmentally harmful emissions. The focus is on the following questions: Will a market economy where environmental policies are restricted to taxes or quotas give the socially efficient outcome for such R&D? Does the answer to this question depend on whether one uses taxes or quotas to regulate emissions? Are market failures associated with environmental innovation different than for innovations elsewhere in the economy?
ocioeconomic and therapy factor influence n self-reported fatigue , anxiety and depression n rheumatoid arthritis patients

Introduction: Fatigue, anxiety and depression are very frequent symptoms in patients with rheumatoid arthritis (RA). Goals: In this study we evaluated the influence of socioeconomic characteristics, therapy and comorbidities on the self-reported high fatigue, anxiety and depression in patients with RA. Method: Multicenter cross-sectional study was performed in 22 health institutions in Serbia during the period from April–August 2014 in population of older RA patients. Selfreported patients health status was measured by: Fatigue Assessment Scale, Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7. Treatment modalities were defined as: (1) non-steroidal anti-inflammatory drugs (NSAIDs) and/or analgesics and/or corticosteroids; (2) synthetic disease-modifying antirheumatic drugs (DMARDs) alone or in combination with corticosteroids and/or NSAIDs and (3) any RA treatment which includes
China-Angola Investment Model

In the aftermath of Angola’s civil war, strong economic relations developed between the country and the People’s Republic of China. Our study addresses China’s investment risks in Angola, considering an infrastructure-for-petroleum partnership between these two countries. The main working hypothesis is that the recovery of Chinese investments made in Angola is has translated into thousands of barrels of petroleum being imported daily from Angola. We analyzed the main economic, social, and political indicators that describe the situation in Angola that could impact the recovery of Chinese loans in the form of oil exports. Data processing implied involved regression-based imputation, MinMax data normalization, the use of the Analytical Hierarchy Process (AHP), and econometric analysis, next to the construction of a composite risk indicator. The results of the econometric analysis highlighted that an increase in the composite risk indicator of 1% leads to a decrease in the quantity of petroleum exported by almost 6377 barrels per day. Because, at least in the short run, the economic diversification in Angola is weak, and the most important asset is its oil, the partnership with China will continue to exist. This cooperation model represents a source of economic growth and infrastructure development for Angola and a source of energy that fuels China—one of the most powerful economies in the world.
THE FEASIBILITY OF SMOOTHED PARTICLE HYDRODYNAMICS FOR MULTIPHASE OILFIELD SYSTEMS

Multiphase flows are common in the oil and gas industry. Computational Fluid Dynamics (CFD) has an important role in understanding such flows with many techniques available. Smoothed Particle Hydrodynamics (SPH) has been chosen as a target for research and has been matched with rotating gas/liquid flows as a suitable test case. A feasibility study has been conducted to assess the likely computational cost of simulating the selected test case using SPH. It shows usable results are achievable with a serial code but higher resolution results will require parallel computing. The study has also shown that the rotating flow will generate high centrifugal accelerations. These would cause unacceptable compressibility and stratification effects if a Weakly Compressible SPH code were to be used. The Incompressible SPH formulation therefore appears preferable.

New Constructs for the Prediction of Self-Initiated International Mobility: An Exploratory Study

This study aims to explore relationships between the motives for international mobility and observed mobility patterns. The key motives of 2,608 skilled expatriate New Zealanders were identified as cultural and travel opportunities, career, economics, affiliations, political environment, and quality-of-life. Mobility patterns, described here as the frequency, duration and cessation of mobility and the nature of the destination in terms of development level and cultural distance, were investigated. Desire for cultural and travel opportunities was the dominant motive, and the best predictor of cessation of mobility and development level of the destination. Career motives predicted duration of mobility and cultural difference of the destination. Linking motivation and actual mobility is a novel contribution to the theorisation of self-initiated mobility. Countries and organisations that understand this linkage may ultimately gain competitive advantage.
ORC Layout: Adaptive GUI Layout with OR-Constraints

We propose a novel approach for constraint-based graphical user interface (GUI) layout based on OR-constraints (ORC) in standard soft/hard linear constraint systems. ORC layout unifies grid layout and flow layout, supporting both their features as well as cases where grid and flow layouts individually fail. We describe ORC design patterns that enable designers to safely create flexible layouts that work across different screen sizes and orientations. We also present the ORC Editor, a GUI editor that enables designers to apply ORC in a safe and effective manner, mixing grid, flow and new ORC layout features as appropriate. We demonstrate that our prototype can adapt layouts to screens with different aspect ratios with only a single layout specification, easing the burden of GUI maintenance. Finally, we show that ORC specifications can be modified interactively and solved efficiently at runtime.
