An experimental assessment of potential freshwater diatom dispersal via waterfowl feathers
Creators: name: Manning, Faye
Publisher: name: University of British Columbia
Year: 2019

description: Dispersal is a fundamental ecological process that can profoundly influence the diversity and functioning of ecosystems. Yet, for microorganisms, dispersal largely remains a “black box”. For freshwater diatoms waterfowl have long been considered potential dispersal vectors, but experimental assessments of this possibility are lacking. I conducted a novel experiment designed to emulate diatom transport by waterfowl feathers, and to test the individual and interactive effects of humidity and transport time on dispersal success (fully factorial design, with N = 8 replicates per treatment combination). Each replicate involved dipping a mallard breast feather in a solution inoculated with a single strain of diatoms (genus Nitzschia), then subjecting the feather to one of 4 humidity levels and one of 4 “transport” durations within a chamber through which air was passed. Finally, the feather was placed in sterile media. I equated dispersal success with evidence of diatom growth after 2 weeks. My experiment indicated strong potential for successful dispersal via feathers overall, and revealed a significant interaction between humidity and transport time: dispersal success significantly declined with increasing transport time under low to moderate humidity levels, but was consistently high under the highest humidity levels. I place these findings in the context of waterfowl dispersal distances and inter-lake distances within the major migratory flyways of North America. In the future, my experimental design should be used to explore potential colonization success of important diatom taxa and waterfowl species to narrow in on aquatic landscapes of interest. My results should also be used alongside actual relative humidity, lake, and flight data to spatially map potential diatom dispersal.

description: It has long been known that complex balanced mass-action systems exhibit a restrictive form of behaviour known as locally stable dynamics. This means that within each compatibility class $\mathcal{C}_{\mathbf{x}_0}$---the forward invariant space where solutions lies---there is exactly one equilibrium concentration and that this concentration is locally asymptotically stable. It has also been conjectured that this stability extends globally to $\mathcal{C}_{\mathbf{x}_0}$. That is to say, all solutions originating in $\mathcal{C}_{\mathbf{x}_0}$ approach the unique positive equilibrium concentration rather than $\partial \mathcal{C}_{\mathbf{x}_0}$ or $\infty$. To date, however, no general proof of this conjecture has been found. In this paper, we approach the problem of global stability for complex balanced systems through the methodology of dividing the positive orthant into regions called strata. This methodology has been previously applied to detailed balanced systems---a proper subset of complex balanced systems---to show that, within a stratum, trajectories are repelled from any face of $\mathbb{R}_{\geq 0}^m$ adjacent to the stratum. Several known global stability results for detailed balanced systems are generalized to complex balanced systems.

description: [Abridged] Investigations of neutron(n)-capture element nucleosynthesis and chemical evolution have largely been based on stellar spectroscopy. However, the recent detection of these elements in several planetary nebulae (PNe) indicates that nebular spectroscopy is a promising new tool for such studies. In PNe, n-capture element abundance determinations reveal details of s-process nucleosynthesis and convective mixing in evolved low-mass stars, as well as the chemical evolution of elements that cannot be detected in stellar spectra. Only one or two ions of a given trans-iron element can typically be detected in individual nebulae. Elemental abundance determinations thus require corrections for the abundances of unobserved ions. Such corrections rely on the availability of atomic data for processes that control the ionization equilibrium of nebulae. Until recently, these data were unknown for virtually all n-capture element ions. For the first five ions of Se, Kr, and Xe -- the three most widely detected n-capture elements in PNe -- we are calculating photoionization cross sections and radiative and dielectronic recombination rate coefficients using the multi-configuration Breit-Pauli atomic structure code AUTOSTRUCTURE. Charge transfer rate coefficients are being determined with a multichannel Landau-Zener code. To calibrate these calculations, we have measured absolute photoionization cross sections of Se and Xe ions at the Advanced Light Source synchrotron radiation facility. These atomic data can be incorporated into photoionization codes, which we will use to derive ionization corrections (hence abundances) for Se, Kr, and Xe in ionized nebulae. These results are critical for honing nebular spectroscopy into a more effective tool for investigating the production and chemical evolution of trans-iron elements in the Universe.

description: Commodity prices consistently increase in developing countries while they barely decline, affecting negatively poor and vulnerable people. This paper examines the role of intermediaries such as collectors, wholesalers, and retailers in the asymmetric transmission of millet prices from producers to consumers in local millet markets in Mali. We use data of local millet prices from the five most important cities in terms of local millet production in Mali namely; Bamako, Segou, Kayes, Koulikoro and Sikasso. Using the Threshold Auto-Regressive (TAR) method developed by Enders and Siklos (2001), at the exogenous threshold, we found an asymmetrical transmission between Koulikoro and Ségou collectors’ market. The result shows that, collectors in Koulikoro promptly transmit price increases while they lately transmit price decline at exogenous threshold. Strong evidence was found to suggest that, collectors in Koulikoro and wholesalers in Sikasso punctually transmit a decrease in millet prices to consumers while they tardily transmit the increase in prices to consumers even though the effect of prices increment are relatively larger than the effect of price decrease at endogenous threshold. By applying a zero exogenous threshold we found a non-asymmetric cointegration between Kayes and Ségou, Sikasso and Ségou ‘collectors market and between Sikasso and Ségou wholesalers’ market. Regardless of the threshold chosen in retailers market, we found symmetric prices transmissions between all the markets pairs. In order to reduce this asymmetric price transmission and to fight against poverty, the authors suggest that decision-makers should consider introducing millet price control in the local markets, especially when millet prices increase spontaneously.

description: We use X-ray Photon Correlation Spectroscopy (XPCS) to probe the dynamics of colloidal particles in polycrystalline ice. During freezing, the dendritic ice morphology and rejection of particles from the ice created regions of high-particle-density, where some of the colloids were forced into contact and formed disordered aggregates. We find that the particles in these high density regions underwent ballistic motion coupled with both stretched and compressed exponential decays of the intensity autocorrelation function, and that the particles' characteristic velocity increased with temperature. We explain this behavior in terms of ice grain boundary migration.

description: The Vela-D region, according to the nomenclature given by Murphy & May (1991), of the star forming complex known as the Vela Molecular Ridge (VMR), has been recently analyzed in details by Olmi et al. (2009), who studied the physical properties of 141 pre- and proto-stellar cold dust cores, detected by the ``Balloon-borne Large-Aperture Submillimeter Telescope'' (BLAST) during a much larger (55 sq. degree) Galactic Plane survey encompassing the whole VMR. This survey's primary goal was to identify the coldest, dense dust cores possibly associated with the earliest phases of star formation. In this work, the dynamical state of the Vela-D cores is analyzed. Comparison to dynamical masses of a sub-sample of the Vela-D cores estimated from the 13CO survey of Elia et al. (2007), is complicated by the fact that the 13CO linewidths are likely to trace the lower density intercore material, in addition to the dense gas associated with the compact cores observed by BLAST. In fact, the total internal pressure of these cores, if estimated using the 13CO linewidths, appears to be higher than the cloud ambient pressure. If this were the case, then self-gravity and surface pressure would be insufficient to bind these cores and an additional source of external confinement (e.g., magnetic field pressure) would be required. However, if one attempts to scale down the 13CO linewidths, according to the observations of high-density tracers in a small sample of sources, then most proto-stellar cores would result effectively gravitationally bound.

description: Datasets are critical for scientific research, playing a role in replication, reproducibility, and efficiency. Researchers have recently shown that datasets are becoming more important for science to function properly, even serving as artifacts of study themselves. However, citing datasets is not a common or standard practice in spite of recent efforts by data repositories and funding agencies. This greatly affects our ability to track their usage and importance. A potential solution to this problem is to automatically extract dataset mentions from scientific articles. In this work, we propose to achieve such extraction by using a neural network based on a BiLSTM-CRF architecture. Our method achieves F1=0.885 in social science articles released as part of the Rich Context Dataset. We discuss future improvements to the model and applications beyond social sciences.

description: We study the electromagnetic Casimir interaction of a compact object contained inside a closed cavity of another compact object. We express the interaction energy in terms of the objects' scattering matrices and translation matrices that relate the coordinate systems appropriate to each object. When the enclosing object is an otherwise empty metallic spherical shell, much larger than the internal object, and the two are sufficiently separated, the Casimir force can be expressed in terms of the static electric and magnetic multipole polarizabilities of the internal object, which is analogous to the Casimir-Polder result. Although it is not a simple power law, the dependence of the force on the separation of the object from the containing sphere is a universal function of its displacement from the center of the sphere, independent of other details of the object's electromagnetic response. Furthermore, we compute the exact Casimir force between two metallic spheres contained one inside the other at arbitrary separations. Finally, we combine our results with earlier work on the Casimir force between two spheres to obtain data on the leading order correction to the Proximity Force Approximation for two metallic spheres both outside and within one another.

Monitoring fireline construction in near real-time with Sentinel-1
Creators: name: Schreiber, Lukas
Publisher: name: University of British Columbia
Year: 2019

description: Near real-time mapping of anthropogenic linear networks (e.g. roads, seismic lines and fireguards) in forests has a range of applications including monitoring rapid management responses to disturbances such as fire. Synthetic aperture radar imagery is well suited for near real time monitoring because microwaves penetrate clouds and smoke, and satellite images are acquired weekly in many parts of the world, assuring regular coverage. In this study, we created maps of fireguard networks constructed during the 2017 wildfires in Alex Fraser Research Forest in interior British Columbia, Canada based on Sentinel-1 SAR image time series and Sentinel-2 image pairs. I developed two methods to summarize the Sentinel-1 backscatter time series in a single summary raster suitable for human interpretation in Google Earth Engine. The first method is to fit a trend line to the backscatter time series for each pixel, and display the value of this line at the start and end of the observation window in red and green. The second is to fit a single-step function and display the left and right tail values along with the R² value of the fit as red, green and blue values. I assessed the utility of these summary images for manual delineation of fireguard networks by simulating the accuracy and timeliness of fireguard detection based on acquisition in near real-time. For reference, I compared these methods with a straightforward before-after analysis of Sentinel-2 multispectral images and with ground truth maps. From the trend line and step function summary images, interpreters detected 22–41% and 24–55% of fireguard length respectively while delineation from multispectral imagery attained a detection rate of 84–86%. Delineation from Sentinel-2 images was most precise with an average deviation of 5–6 metres from the ground truth, followed by the trend image with 8–15 metres deviation and the step image with 11–16 metres. In the best case, a change was detected based on a step image within 6 days. The developed method can be used to monitor linear feature construction where more accurate methods are unavailable.
title: Sizing, dynamic modeling and simulation of a solar-wind-hydrogen power system of the MUN explorer autonomous underwater vehicle

Publisher: name: Memorial University of Newfoundland

description: In this doctoral research dissertation, sizing, dynamic modeling, and simulation of a solar, wind and hydrogen power system of the MUN Explorer Autonomous Underwater Vehicle (AUV) have been explored, integrating a Polymer Electrolyte Membrane (PEM) fuel cell into an existing power system which uses a lithium ion battery as the main source of its energy. Along with the batteries the integrated fuel cell was designed to power the MUN Explorer AUV to increase its hours of operation and reduce the number of batteries. The installation of hydrogen and oxygen gas tanks next to the batteries augmented the buoyancy force underwater. An electrolyzer powered by solar and wind energy, was used to produce hydrogen. The produced hydrogen was then stored in gas cylinders. A PEM fuel cell was used to consume the hydrogen gas inside the MUN Explorer AUV. The fuel cell was connected to a DC / DC Boost Converter to increase the output voltage from 24 to 48 V, as required by the battery and DC motor. It was proposed that the renewable excess energy be stored and used for recharging a battery. The system design is based on MUN Explorer data sheets and system dynamic simulation results. The system sizing was performed using Hybrid Optimization Model for Electrical Renewable (HOMER) software. The dynamic model was then built in MATLAB / Simulink environment to give a better understanding of the system’s behaviour. A PI controller was applied in the dynamic model to maintain the operating conditions such as motor speed, DC bus voltage and the load torque. The simulation of dynamic models and experiment results in hydrogen production and consumption were compared and found to have an acceptable error. The results from hydrogen production systems (solar and wind) were measured to be 7.0 ml/min. The PI controller provided satisfactory results in terms of maintaining the same operating conditions of the MUN Explorer AUV with a fuel cell.

description: The Hypervelocity Star survey presents the currently largest sample of radial velocity measurements of halo stars out to 80 kpc. We apply spherical Jeans modeling to these data in order to derive the mass profile of the Galaxy. We restrict the analysis to distances larger than 25 kpc from the Galactic center, where the density profile of halo stars is well approximated by a single power law with logarithmic slope between -3.5 and -4.5. With this restriction, we also avoid the complication of modeling a flattened Galactic disk. In the range 25 < r < 80 kpc, the radial velocity dispersion declines remarkably little; a robust measure of its logarithmic slope is between -0.05 and -0.1. The circular velocity profile also declines remarkably little with radius. The allowed range of V_c(80 kpc) lies between 175 and 231 km/s, with the most likely value 193 km/s. Compared with the value at the solar location, the Galactic circular velocity declines by less than 20% over an order of magnitude in radius. Such a flat profile requires a massive and extended dark matter halo. The mass enclosed within 80 kpc is 6.9(+3.0-1.2) 10^11 Msun. Our sample of radial velocities is large enough that the biggest uncertainty in the mass is not statistical but systematic, dominated by the density slope and anisotropy of the tracer population. Further progress requires modeling observed datasets within realistic simulations of galaxy formation.

description: The hadron loop effect is conjectured to be important in understanding discrepancies between the observed states in experiments and the theoretical expectations of non-relativistic potential model. We present that, in an easily operable procedure, the hadron loop effect could shift the poles downwards to reduce the differences and provide better descriptions of both the masses and the total widths, at least, of the radial quantum number $n=1$ charmed and charmed-strange states. The $1^1P_1-1^3P_1$ mixing phenomena could be naturally explained due to their couplings with common channels. The newly observed $D$ states are also addressed, but there are still some problems remaining unclear.

description: The role and importance of innovation are recognized as one of the main drivers of development and sustainability in various areas of activity. In Portugal, innovation applied to healthcare has resulted in the development of several digital tools to support decision-making. However, these tools do not seem to meet the users' needs and expectations. This article focuses on the development of an application whose objective is to provide citizens with accurate, up-to-date and expanded information that allows him to make thoughtful choices about the required or needed healthcare provider. Interviews were conducted with several specialists, followed by the construction of a tested and validated mockup with a focus group. Findings show that this application reports benefits, not only for citizens, enabling greater awareness of healthcare provision, but also for policy makers, by identifying the factors that influence citizens' decisions and helping in the design of informed and appropriate policies for different geographical contexts.

An Overview of the Distributed Oceanographic Data System (DODS)
Creators: name: Gallagher, James
Publisher: name: Zenodo
Year: 1995

description: This slide deck was based on presentations made at the April 1995 TOS meeting in Newport RI. and the Nov. 1995 SISIC meeting in Washington, D.C. It has been updated with version 2 information that was not presented at either of those meetings. The original overview presentation describes version 1.x of DODS.

Summary of the slide deck: 

The Distributed Oceanographic Data System (DODS) is a network-based system providing direct access to oceanographic data over the Internet. DODS is designed to meet the requirements of oceanographers, data archive maintainers, and software developers. DODS allows data to be accessed through servers distributed across the internet, while maintaining data in its original format. It employs a single protocol to access all data, allowing for compatibility with various programs. DODS utilizes existing software for both servers and client programs, enabling easy adaptation and integration with legacy systems.

The current status of DODS includes the release of version 2, featuring new capabilities such as constraint expressions, error objects, and better use of HTTP/MIME standards. URI/MIT has developed data servers and client libraries, with other institutions like JPL and the University of Maryland also contributing to the project. Future plans include expanding client support and enhancing error handling, although the current design has known weaknesses such as limitations in data types and translation models.

Overall, DODS aims to provide a flexible and powerful system for accessing and analyzing oceanographic data over the internet. Ongoing efforts aim to improve its functionality and address existing weaknesses.

description: We introduce the notions of in-betweenness and monotonicity with respect to a metric, for operator means. These notions can be seen as generalising their natural counterpart for scalar means, and as a relaxation of the notion of geodesity. We exhibit two classes of non-trivial means that are monotonic with respect to the Euclidean metric. We also show that all Kubo-Ando means are monotonic with respect to the trace metric, which is the natural metric for the geometric mean.

description: A literacia digital em saúde compreende práticas e competências que envolvem valores sociais e culturais e atuam no contexto tecnológico. As intervenções digitais podem ser usadas para dar suporte a programas de educação e promoção da saúde. DEEP é uma intervenção digital psicoeducativa, suportada em recursos audiovisuais, que pretende oferecer um conjunto de recursos que permitam aos Estudantes Universitários Portugueses conhecer melhor o fenómeno da depressão como doença. São poucos os relatos existentes sobre desenhos metodológicos de suporte a este tipo de intervenções. Este artigo apresenta o desenho metodológico concebido com o intuito de avaliar o impacto da intervenção DEEP nos conhecimentos que os estudantes portugueses têm sobre depressão. O estudo randomizado DEEP compreende 4 fases: estudo piloto, recrutamento de participantes, disponibilização da intervenção e Follow-up. Pretende-se que este desenho metodológico permita aferir o grau de eficácia e o contributo da narrativa transmedia utilizada na intervenção DEEP, como ferramenta ao serviço da literacia em depressão. Considera-se ainda que o desenho metodológico apresentado poderá contribuir para aprofundar conhecimento acerca das abordagens metodológicas mais apropriadas no domínio do estudo realizado.

Sea Quark Flavor Asymmetry of Hadrons in Statistical Balance Model

Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We derive a Menta Carlo method to simulate kinetic equilibrium ensemble, and get the same sea-quark flavor asymmetry as the linear equations method in statistical model. In the recent paper, we introduce the spilt factors to indicate the quarks' or gluons' spilt $g\rightarrow q\bar{q}(gg)$ and $q\rightarrow qg$ ability. We obtain the almost fixed asymmetry value $0.12-0.16$ which consists with experimental measurements for proton, when the spilt factors vary in a very wide range over four orders of magnitude. So, we proof the sea quark asymmetry can be derived from statistic principle and not sensitively dependents on the dynamics details of quarks and gluons in proton. We also apply the Menta Carlo method of statistical model to predict the sea-quark asymmetry values for $K$ mesons, octet baryons $Σ$,$Ξ$ and $Δ$ baryons, even for exotic pentaquark states. All these asymmetry values just only dependent on the valence quarks numbers in those hadrons.

description: One develops {\em ab initio} the theory of rational/birational maps over reduced, but not necessarily irreducible, projective varieties in arbitrary characteristic. A numerical invariant of a rational map is introduced, called the Jacobian dual rank. It is proved that a rational map in this general setup is birational if and only if the Jacobian dual rank attains its maximal possible value. Even in the "classical" case where the source variety is irreducible there is some gain for this invariant over the degree of the map as it is, on one hand, intrinsically related to natural constructions in commutative algebra and, on the other hand, is effectively straightforwardly computable. Applications are given to results so far only known in characteristic zero. In particular, the surprising result of Dolgachev concerning the degree of a plane polar Cremona map is given an alternative conceptual angle.

description: The evolution in user interfaces has shown a trend in the use of tangible interfaces, especially those that promote a sensory experience. The use of this type of resource is interesting in different contexts, among which are the scenarios where the sensory aspect is decisive for interaction, such as in the use of assistive technologies. This study aims to present the results of a research project, which had the main goal to promote the play of children with Cerebral Palsy (CP), using a multisensory device as the main element in games proposed at children with CP. CP refers to a series of clinical syndromes characterized by motor disorders and permanent postural changes that may or may not be associated with cognitive dysfunction and speech disorders. Due to the restricted motor condition, involvement in games and play becomes difficult for children with CP. The challenge is to address the use of assistive technologies, through a multisensory robotic device, in the development of interactive games for children with PC. The use of a robotic device allows the manipulation of the ball remotely, which is useful for children with physical disabilities, proving to be a feasible alternative to promote playing children with CP.
