description: The proton's transverse polarization structure is examined in terms of the Lorentz-covariant Pauli-Lubanski vector in QCD. We find that there are contributions from leading, subleading, and next-to-subleading partonic contributions in the light-front system of coordinates. The subleading and next-to-subleading contributions are related to the leading one through Lorentz symmetry. And the leading contribution obeys a simple partonic angular momentum sum rule that gives a clear physical interpretation to a relation known previously.

Systematic errors in measuring parameters of non-spinning compact binary coalescences with post-Newtonian templates

description: We study the astrophysical impact of inaccurate and incomplete modeling of the gravitational waveforms from compact binary coalescences (CBCs). We do so by the matched filtering of complete inspiral-merger-ringdown (IMR) signals with a bank of inspiral-phase templates modeled after the 3.5 post-Newtonian TaylorT1 approximant. The rationale for the choice of the templates is threefold: (1) The inspiral phase of the Phenomenological signals, which are an example of complete IMR signals, is modeled on the same TaylorT1 approximant. (2) In the low-mass limit, where the merger and ringdown phases last much shorter than the inspiral phase, the errors should tend to vanishingly small values and, thus, provide an important check on the numerical aspects of our simulations. (3) Since the binary black hole (BBH) signals are not yet known for mass-ratios above ten and since signals from CBCs involving neutron stars are affected by uncertainties in the knowledge of their equation of state, inspiral templates are still in use in searches for those signals. The results from our numerical simulations are compared with analytical calculations of the systematic errors using the Fisher matrix on the template parameter space. We find that the loss in signal-to-noise ratio (SNR) can be as large as 60% even for binary black holes with component masses m1 = 13M\odot and m2 = 20M\odot. Also, the estimated total-mass for the same pair can be off by as much as 20%. Both of these are worse for some higher-mass combinations. Even the estimation of the symmetric mass-ratio η suffers a nearly 20% error for this example, and can be worse than 50% for the mass ranges studied here. These errors significantly dominate their statistical counterparts (at a nominal SNR of 10). It may, however, be possible to mitigate the loss in SNR by allowing for templates with unphysical values of η.

description: With the SAP HANA database, SAP offers a high-performance in-memory hybrid-store database. Hybrid-store databases---that is, databases supporting row- and column-oriented data management---are getting more and more prominent. While the columnar management offers high-performance capabilities for analyzing large quantities of data, the row-oriented store can handle transactional point queries as well as inserts and updates more efficiently. To effectively take advantage of both stores at the same time the novel question whether to store the given data row- or column-oriented arises. We tackle this problem with a storage advisor tool that supports database administrators at this decision. Our proposed storage advisor recommends the optimal store based on data and query characteristics; its core is a cost model to estimate and compare query execution times for the different stores. Besides a per-table decision, our tool also considers to horizontally and vertically partition the data and manage the partitions on different stores. We evaluated the storage advisor for the use in the SAP HANA database; we show the recommendation quality as well as the benefit of having the data in the optimal store with respect to increased query performance.

title: Is there a puddling surface preference in a population of captive butterflies?
Creators: name: Pooler, Angel
Publisher: name: Oxford Brookes University
Year: 2020

description: This research revolves around the question ‘Do captive butterflies have a surface preference for participating in puddling behaviour?’. Puddling, or mud puddling, is a behaviour that’s carried out across many insects, but is most commonly seen in Lepidopterans (butterflies and moths). Its known as a form of feeding for butterflies, allowing them to obtain the appropriate nutrients including sodium, that are needed for them to carry out a variety of physiological and ethological functions; one being successful reproduction. In both captive and wild populations puddling can take place on a variety of surfaces, including, but not limited to: mud, blood, dung, urine and sand. To answer this question, observations of a population of captive butterflies will be conducted to note their puddling behaviour across many surfaces. It is believed that these observations will allow for the most natural behaviour to be expressed as well as gaining maximum data. Once data is collected and analysed it is believed that mud will be the most popular surface amongst the butterflies, as it is usually the most readily available surface for puddling. This research is important for a number of reasons including enhancing care of captive and wild populations of butterflies, and therein improving their numbers through giving them optimal chance of reproduction and longevity. This research is critical, as insects globally are facing a dramatic reduction in numbers, with as much as a 98% decrease across the past 35 years. By understanding smaller areas of insect behaviour, we may be able to curb this decline and increase population numbers.

We identify the relevant growth regime and present a possible explanation of this effect. We show that preferential orientation provides increased optical read-out contrast for NV multi-spin measurements, including enhanced AC magnetic field sensitivity, thus providing an important step towards high fidelity multi-spin-qubit quantum information processing, sensing and metrology.

From Cooperative Scans to Predictive Buffer Management

description: In analytical applications, database systems often need to sustain workloads with multiple concurrent scans hitting the same table. The Cooperative Scans (CScans) framework, which introduces an Active Buffer Manager (ABM) component into the database architecture, has been the most effective and elaborate response to this problem, and was initially developed in the X100 research prototype. We now report on the the experiences of integrating Cooperative Scans into its industrial-strength successor, the Vectorwise database product. During this implementation we invented a simpler optimization of concurrent scan buffer management, called Predictive Buffer Management (PBM). PBM is based on the observation that in a workload with long-running scans, the buffer manager has quite a bit of information on the workload in the immediate future, such that an approximation of the ideal OPT algorithm becomes feasible. In the evaluation on both synthetic benchmarks as well as a TPC-H throughput run we compare the benefits of naive buffer management (LRU) versus CScans, PBM and OPT; showing that PBM achieves benefits close to Cooperative Scans, while incurring much lower architectural impact.

description: We study field theories in two spacetime dimensions invariant under a chiral scaling symmetry that acts only on right-movers. The local symmetries include one copy of the Virasoro algebra and a U(1) current algebra. This differs from the 2d conformal group, but in some respects is equally powerful in constraining the theory. In particular, the symmetries on a torus lead to modular covariance of the partition function, which is used to derive a universal formula for the asymptotic density of states. For an application we turn to the holographic description of black holes in quantum gravity, motivated by the fact that the symmetries in the near horizon geometry of any extremal black hole are identical to those of a 2d field theory with chiral scaling. We consider two examples: black holes in warped AdS_3 in topologically massive gravity, and in string theory. In both cases, the density of states in the 2d field theory reproduces the Bekenstein-Hawking entropy of black holes in the gravity theory.

description: We study the microwave induced ratchet transport of two-dimensional electrons on an oriented semidisk Galton board. The magnetic field symmetries of ratchet transport are analyzed in presence of electron-electron interactions. Our results show that a magnetic field asymmetric ratchet current can appear due to two contributions, a Hall drift of the rectified current that depends only weakly on electron-electron interactions and a breaking of the time reversal symmetry due to the combined effects of interactions and magnetic field. In the latter case, the asymmetry between positive and negative magnetic fields vanishes in the weak interaction limit. We also discuss the recent experimental results on ratchet transport in asymmetric nanostructures.

Motherly narratives: motherhood, caring employment and the tensions of Chinese kindergarten teachers

description: This thesis examines kindergarten teachers’ understandings of and reflections on care practices and early childhood education in China. Drawing on in-depth interviews with 25 kindergarten teachers, this thesis explores how the daily care is culturally grounded, gendered understandings of motherhood as the pinnacle of care influence the work of kindergarten teachers. While attempting to frame themselves as professional childhood educators, these kindergarten teachers push back against gendered understandings of care work as the “natural” domain of women, but simultaneously support gendered essentialism when they use motherhood as the model through which they understand the work of their colleagues and themselves. By comparing their care work as mothers and as educators, this thesis argues that these female kindergarten teachers are expected to provide selfless, loving motherly care by broader, hegemonic societal forces that they inadvertently take on.

description: In recent years, there has been a substantial amount of work on large-scale data analytics using Hadoop-based platforms running on large clusters of commodity machines. A less-explored topic is how those data, dominated by application logs, are collected and structured to begin with. In this paper, we present Twitter's production logging infrastructure and its evolution from application-specific logging to a unified "client events" log format, where messages are captured in common, well-formatted, flexible Thrift messages. Since most analytics tasks consider the user session as the basic unit of analysis, we pre-materialize "session sequences", which are compact summaries that can answer a large class of common queries quickly. The development of this infrastructure has streamlined log collection and data analysis, thereby improving our ability to rapidly experiment and iterate on various aspects of the service.

description: In this work we investigate the process of pattern formation in a two dimensional domain for a reaction-diffusion system with nonlinear diffusion terms and the competitive Lotka-Volterra kinetics. The linear stability analysis shows that cross-diffusion, through Turing bifurcation, is the key mechanism for the formation of spatial patterns. We show that the bifurcation can be regular, degenerate non-resonant and resonant. We use multiple scales expansions to derive the amplitude equations appropriate for each case and show that the system supports patterns like rolls, squares, mixed-mode patterns, supersquares, hexagonal patterns.
title: The Sedimentary Petrography, Depositional Environment and Tectonic Setting of the Aldwell Formation, Northern Olympic Peninsula, Washington
Creators: name: Marcott, Keith
Publisher: name: Western Washington University
Year: 1984

description:
The upper Eocene Aldwell Formation crops out in an east-west trending band across the northern Olympic Peninsula, Washington. Petrographic analyses indicate that the Aldwell Formation has lithologically distinctive eastern and western portions. The rocks of the eastern Aldwell are basalt-rich lithic greywackes; their mean compositions are Qm-F-Lt: 5- 22-73 and polycrystalline quartz-volcanic rock fragments-total sedimentary rock fragments: 1-78-21. The rocks of the western Aldwell are chert-rich lithic arenites; their mean compositions are Qm-F-Lt: 27-19-54 and polycrystalline quartz-volcanic rock fragments-total sedimentary rock fragments: 66-11-23.

Similarities in texture, composition, and alteration products suggest that the basalts of the Crescent seamount province as the likely source for the sediments of the eastern rocks. Since the basalts of the Crescent seamount province crop out both to the north (Metchosin Volcanics) and south (Crescent Formation) of the Aldwell Formation, no definite conclusions can be drawn regarding the provenance of the eastern Aldwell sediments. However, a northern source is inferred based on the restriction of abundant basaltic detritus to the eastern rocks and a southward transport direction for the olistostromal blocks in a conglomerate unit near Lake Aldwell.

The provenance of the sediments in the western portion of the Aldwell Formation is speculative. A terrane located to the southwest of Vancouver Island during the late Eocene is proposed as the source of these sediments.

The rocks in the eastern portion of the Aldwell Formation are predominantly thin-bedded, laminated siltstones with interbedded fine sands. The rocks in the western portion of the Aldwell Formation are thin-bedded siitstones with interbedded fine sands, commonly in thin lenses; coarse sandstone and conglomerate are also present. The eastern rocks are interpreted as having been deposited in an outer fan environment and the western rocks were deposited in a mid-fan environment, but the different lithologies indicate that deposition took place on two separate fans within the Juan de Fuca basin rather than in two areas of the same fan.

A model for the tectonic setting of the Juan de Fuca basin and surrounding area during the deposition of the Aldwell Formation is proposed in which the Crescent seamount province, moving northeast on either the Kula or Farallon plate, converged against an allochthonous terrane then located near Vancouver Island, resulting in uplift and southerly transport of Aldwell sediments.

description: When discriminating dynamic noisy sensory signals, human and primate subjects achieve higher accuracy when they take more time to decide, an effect attributed to accumulation of evidence over time to overcome neural noise. We measured the speed and accuracy of twelve freely behaving rats discriminating static, high contrast photographs of real-world objects for water reward in a self-paced task. Response latency was longer in correct trials compared to error trials. Discrimination accuracy increased with response latency over the range of 500-1200ms. We used morphs between previously learned images to vary the image similarity parametrically, and thereby modulate task difficulty from ceiling to chance. Over this range we find that rats take more time before responding in trials with more similar stimuli. We conclude that rats' perceptual decisions improve with time even in the absence of temporal information in the stimulus, and that rats modulate speed in response to discrimination difficulty to balance speed and accuracy.

description: Database backups have traditionally been used as the primary mechanism to recover from hardware and user errors. High availability solutions maintain redundant copies of data that can be used to recover from most failures except user or application errors. Database backups are neither space nor time efficient for recovering from user errors which typically occur in the recent past and affect a small portion of the database. Moreover periodic full backups impact user workload and increase storage costs. In this paper we present a scheme that can be used for both user and application error recovery starting from the current state and rewinding the database back in time using the transaction log. While we provide a consistent view of the entire database as of a point in time in the past, the actual prior versions are produced only for data that is accessed. We make the as of data accessible to arbitrary point in time queries by integrating with the database snapshot feature in Microsoft SQL Server.

Habitats Menacés et Zones Tropicales Importantes Pour les Plantes (ZTIP) de Guinée, Afrique de l'Ouest
Publisher: name: Royal Botanic Gardens, Kew research repository
Year: 2019

description: La Guinée compte plus de 250 espèces répertoriées de plantes uniques et menacées, plus que tout
autre pays d'Afrique de l'Ouest. Assurer leur protection ne devrait pas uniquement être une priorité
nationale, mais une priorité mondiale.
Parmi ces espèces – ces ressources naturelles – il existe potentiellement de nouveaux médicaments,
matériaux, et aliments qui, grâce à la recherche scientifique, pourraient améliorer les moyens de
subsistance des Guinéens.
Cependant, le temps presse. Déjà 35 des espèces de plantes les plus rares de Guinée sont peut-être
éteintes, et 25 de ces espèces sont ou étaient uniques au monde en Guinée. Malgré nos recherches,
ces espèces n'ont pas été aperçues depuis plus de 50 ans et semblent avoir été détruites par
inadvertance à la suite d'activités humaines.
La Guinée continuera de se développer à travers une exploitation minière plus importante, une
agriculture améliorée, de nouvelles routes, de nouvelles industries, de plus grandes villes, ainsi que
des infrastructures supplémentaires pour les soutenir. Ce développement futur aura un impact sur
l'environnement naturel.
Dans ce livre, nous documentons les habitats de plantes les plus menacés de Guinée et les 22
zones les plus importantes, non seulement pour la conservation de ces habitats, mais également
pour les espèces de plantes menacées qu’ils contiennent. Si ces 22 ZTIP répertoriées dans cet
ouvrage peuvent être protégées, une grande partie du patrimoine national de la Guinée en
termes de ressources en plantes sauvages sera alors sauvegardée. Au total, ces 22 zones occupent
8 702 km², soit 3,5% de la superficie de la Guinée. Plusieurs de ces zones sont déjà protégées,
telles que Nimba et Ziama. D'autres ne sont pas protégées, comme par exemple Kounounkan qui
abrite pourtant plus d’espèces uniques au monde que tout autre lieu de Guinée, et la destruction
de la forêt s’y poursuit. Les 22 Zones Tropicales Importantes pour les Plantes répertoriées dans
ce livre incluent :
–– Plus de 60% des espèces de plantes menacées de Guinée
–– Les sites documentés les plus riches en espèces de Guinée
–– Des espèces socio-économiques indigènes importantes
–– Les zones de la plus haute qualité de chacun des neuf habitats menacés
Nous espérons que ce livre, qui est le résultat des efforts communs de scientifiques guinéens et
britanniques, de responsables gouvernementaux, et d’équipes d’ONG, permettra de renforcer la
protection de la diversité végétale de la Guinée et de mieux la gérer.

description: A solid-state nanopore can electrophoretically capture a DNA molecule and pull it through in a folded configuration. The resulting ionic current signal indicates where along its length the DNA was captured. A statistical study using an 8 nm wide nanopore reveals a strong bias favoring the capture of molecules near their ends. A theoretical model shows that bias to be a consequence of configurational entropy, rather than a search by the polymer for an energetically favorable configuration. We also quantified the fluctuations and length-dependence of the speed of simultaneously translocating polymer segments from our study of folded DNA configurations.

description: We experimentally demonstrate a new optical filter design based on a vertically coupled photonic crystal cavity and a bus waveguide monolithically integrated on the silicon on insulator platform. The use of a vertically coupled waveguide gives flexibility in the choice of the waveguide material and dimensions, dramatically lowering the insertion loss while achieving very high coupling efficiencies to wavelength scale resonators

description: This paper describes the system architecture of the Vertica Analytic Database (Vertica), a commercialization of the design of the C-Store research prototype. Vertica demonstrates a modern commercial RDBMS system that presents a classical relational interface while at the same time achieving the high performance expected from modern "web scale" analytic systems by making appropriate architectural choices. Vertica is also an instructive lesson in how academic systems research can be directly commercialized into a successful product.

description: In an increasing number of applications, it is of interest to recover an approximately low-rank data matrix from noisy observations. This paper develops an unbiased risk estimate---holding in a Gaussian model---for any spectral estimator obeying some mild regularity assumptions. In particular, we give an unbiased risk estimate formula for singular value thresholding (SVT), a popular estimation strategy which applies a soft-thresholding rule to the singular values of the noisy observations. Among other things, our formulas offer a principled and automated way of selecting regularization parameters in a variety of problems. In particular, we demonstrate the utility of the unbiased risk estimation for SVT-based denoising of real clinical cardiac MRI series data. We also give new results concerning the differentiability of certain matrix-valued functions.

Chemical Timescales in the Atmospheres of Highly Eccentric Exoplanets
Creators: name: Visscher, Channon
Publisher: name: arXiv
Year: 2012
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Close-in exoplanets with highly eccentric orbits are subject to large variations in incoming stellar flux between periapse and apoapse. These variations may lead to large swings in atmospheric temperature, which in turn may cause changes in the chemistry of the atmosphere from higher CO abundances at periapse to higher CH4 abundances at apoapse. Here we examine chemical timescales for COCH4 interconversion compared to orbital timescales and vertical mixing timescales for the highly eccentric exoplanets HAT-P-2b and CoRoT-10b. As exoplanet atmospheres cool, the chemical timescales for COCH4 tend to exceed orbital and/or vertical mixing timescales, leading to quenching. The relative roles of orbit-induced thermal quenching and vertical quenching depend upon mixing timescales relative to orbital timescales. For both HAT-P-2b and CoRoT-10b, vertical quenching will determine disequilibrium COCH4 chemistry at faster vertical mixing rates (Kzz > 10^7 cm^2 s^-1), whereas orbit-induced thermal quenching may play a significant role at slower mixing rates (Kzz < 10^7 cm^2 s^-1). The general abundance and chemical timescale results - calculated as a function of pressure, temperature, and metallicity - can be applied for different atmospheric profiles in order to estimate the quench level and disequilibrium abundances of CO and CH4 on hydrogen-dominated exoplanets. Observations of CO and CH4 on highly eccentric exoplanets may yield important clues to the chemical and dynamical properties of their atmospheres.

Interactive Analytical Processing in Big Data Systems: A Cross-Industry Study of MapReduce Workloads

description: Within the past few years, organizations in diverse industries have adopted MapReduce-based systems for large-scale data processing. Along with these new users, important new workloads have emerged which feature many small, short, and increasingly interactive jobs in addition to the large, long-running batch jobs for which MapReduce was originally designed. As interactive, large-scale query processing is a strength of the RDBMS community, it is important that lessons from that field be carried over and applied where possible in this new domain. However, these new workloads have not yet been described in the literature. We fill this gap with an empirical analysis of MapReduce traces from six separate business-critical deployments inside Facebook and at Cloudera customers in e-commerce, telecommunications, media, and retail. Our key contribution is a characterization of new MapReduce workloads which are driven in part by interactive analysis, and which make heavy use of query-like programming frameworks on top of MapReduce. These workloads display diverse behaviors which invalidate prior assumptions about MapReduce such as uniform data access, regular diurnal patterns, and prevalence of large jobs. A secondary contribution is a first step towards creating a TPC-like data processing benchmark for MapReduce.

title: The Effect of Experience-Based Prototypes on Spatial Memory
Creators: name: Williams, Michael L.
Publisher: name: Western Washington University
Year: 2018

description:
The Category Adjustment (CA) model of spatial memory (Huttenlocher, Hedges, & Duncan, 1991) explains how bias towards the centers of spatial categories occurs when recalling locations for target objects. According to the model, this error is the product of Bayesian combination between the rapidly-deteriorating metric information of an object and its longer-lasting categorical information, a process which reduces error variance over time. This adjustment is robust, but previous testing has mainly relied upon remembering simple targets (e.g., dots) in geometric figures. Few studies have addressed whether objects’ real-world expectations are incorporated into this paradigm and, if so, how this information is used. In the present study, participants from a major public university completed a dot-localization task in an ecologically-valid “table” setting. Targets were pictures of everyday objects one might expect in one of two spatial regions: in the center of a table and towards the edge of a table (e.g., a candle or a cup, respectively). I expected participants’ responses would rely on and bias towards long-term prototypes as opposed to the default. On average, responses biased away from the center, with Central objects exhibiting greater magnitudes of bias. A significant portion of responses were replaced on or beyond the default prototype, suggesting participants used their imagined positions as landmarks. Differences between groups suggest possible ways in which long-term prototypes are used. The data will help us understand the contribution of experience-based, long-term prototypical locations for real-world objects in the combinatory processes of spatial memory.
title: Probing the catalytic properties of Ni-based bimetallic phosphides for deep hydrodesulfurization
Creators: name: Topalian, Peter J.
Publisher: name: Western Washington University
Year: 2017

description:
Global demand for transportation fuels continues to rise while environmental standards for sulfur impurities in fuels have become more stringent. Upgrading crude oil feed stocks via deep hydrodesulfurization (HDS) is necessary to meet the ultra-low sulfur standards for transportation fuels. Transition metal phosphides (e.g. Ni2P, Ru2P) represents a new class of hydrotreating catalysts that show promise for improved HDS properties relative to conventional molybdenum sulfide based catalysts. Incorporating a second metal into Ni2P can influence the surface properties and be used to tailor the catalytic properties (activity, selectivity) for improved hydrotreating performance. Bimetallic phosphides catalysts having the formulas NixM­­­2-x­P/SiO2 (M = Ru, Rh) were synthesized over a range of compositions. Metal hypophosphite precursors prepared via incipient wetness were reduced via temperature programmed reduction (TPR). The resulting catalysts were characterized using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and CO chemisorption. HDS properties were probed using 4,6-dimethyldibenzothiophene (4,6-DMDBT) as a model compound. The XRD patterns showed single phase and phase-segregated materials having average crystallize sizes of 5-10 nm. CO chemisorption measurements showed an increase in active site density for the higher nickel content catalysts (e.g. Ni1.85Ru0.15P/SiO2). HDS measurements were carried out using a model feed of 1000 ppm 4,6-DMDBT in decalin over a range of temperatures (533-653 K). A substantial increase in the TOFs and HDS activity was observed for the bimetallic phosphides having high nickel contents. For the NixRh2-xP/SiO2 series, the product selectivity was observed to change with metal composition; for Rh-rich phases (x < 0.25), the hydrogenation product (3,3’-dimethylbicyclohexane) was favored while for Ni-rich compositions (x > 0.25) the partially hydrogenated product (3,3’-dimethylcyclohexylbenzene) dominated.
