description: Age-related cognitive decline is a growing public health issue as increases in life expectancy are expected to substantially raise the prevalence of cognitive impairment and dementia. An estimated 46.8 million individuals are currently living with dementia, with the global prevalence expected to double every 20 years. Emerging evidence suggests that ambient air pollution from traffic and other sources may be an important risk factor for cognitive decline in addition to its association with other cardiovascular and neurological outcomes.
      The aim of this dissertation was to first investigate the association between long-term exposure to ambient air pollution and cognitive decline among older adults in an urban population within Northern Manhattan. I then set out to assess specific mechanisms involved in the association between long-term exposure to ambient air pollution and cognitive decline, specifically investigating the ApoE4 allele, age, and current smoking behavior as effect modifiers of the association between long-term exposure to ambient air pollution and cognitive decline.
      I found evidence of an adverse effect of ambient air pollution on the cognitive functioning of older adults. Overall, exposure to higher levels of ambient air pollution was highly predictive of lower cognitive scores, but at baseline only.  Contrary to the current hypothesis, limited evidence was found for an association between estimates of air pollution and trajectories of cognitive decline. The patterns of effect were similar across pollutant types and cognitive domains in this aging, urban population. I found strong evidence of effect modification by smoking status, where contrary to the hypothesis; the overall effects of ambient air pollution on cognition and cognitive decline were stronger among individuals who never smoked. The impact of effect modification by age category was most prominent in the memory and language cognitive domains. Among individuals less than 75 years old at baseline, there was a stronger association between a one IQR increase in air pollutants and cognitive domain scores at baseline as compared to individuals 75 years and older.  I did not observe conclusive evidence of an association between air pollution and cognition in models stratified by APOE-4 status.
      To my knowledge, this is the largest study to analyze the association of ambient air pollution on cognition and cognitive decline over time in a racially and ethnically diverse sample. These results further support the current evidence on the role of air pollution on accelerated cognitive aging and brain health.
Looking At The Whole Child Through Student Health Profiles:  A Latent Class Analysis of CDC 2019 National Youth Risk Behavior Survey Data

description: The purpose of this research is to discover the extent to which there is a typology of students’ health risk behaviors and to what extent are those typologies associated with academic achievement using the 2019 national Youth Risk Behavior Survey (YRBS) dataset. This is a secondary data analysis study using a national representative sample (n=11,410) of high school students, grades 9 to 12, in the United States. YRBS is a national school-based, paper-based 99-item survey used to assess 121 health-related behaviors among all high school students in the United States and is biennially conducted by the Centers for Disease Control and Prevention (CDC, 2020). While research efforts on health and academic achievement is vastly growing, there is a limited number of studies that are analyzing multiple health-risk behaviors concurrently as well as exploring their potential impacts on educational outcomes. Furthermore, previous studies have utilized cluster and/ or factor analyses. However, this statistical approach will show how students are clustered into groups and does not provide information such as the probability that a given student is bullied or suicidal. A 3-step Latent Class Analysis (LCA) was conducted to identify and understand the various profiles of students who experienced and/ or were exposed to certain health-risk behaviors. The health-risk behaviors of interest, the latent variables, were school-related violence, physical activity, screen time, and sleep. Using LCA, results show that there are four significantly different typologies, or profiles, of student health-risk behaviors: Level 1 The Most Support Needed (TMSN), Level 2 Suicide Prevention Needed (SPN), Level 3 Coping Mechanism for Bullying Needed (CMBN), Level 4 Least Support Needed (LSN). In tandem, contextual factors such as age, sex, grade level, race and ethnicity were significantly associated with the odds of belonging to some of the groups. This study is connected to longer-term work. Implications of these groupings on school policies, student health outcomes, and building a school-based coordinated health system will be discussed.

description: We present a novel algorithm to match GPS trajectories onto maps offline (in batch mode) using techniques borrowed from the field of force-directed graph drawing. We consider a simulated physical system where each GPS trajectory is attracted or repelled by the underlying road network via electrical-like forces. We let the system evolve under the action of these physical forces such that individual trajectories are attracted towards candidate roads to obtain a map matching path. Our approach has several advantages compared to traditional, routing-based, algorithms for map matching, including the ability to account for noise and to avoid large detours due to outliers in the data whilst taking into account the underlying topological restrictions (such as one-way roads). Our empirical evaluation using real GPS traces shows that our method produces better map matching results compared to alternative offline map matching algorithms on average, especially for routes in dense, urban areas.

description: Using the World Bank Public Expenditure Tracking Survey (PETS) 2004 data, propensity score matching is utilized to infer a causal impact of private tutoring on the numeracy, literacy, and total outcomes for fourth grade public school students. This research finds that students who self-report that they participate in private tutoring everyday as compared to their peers who never participate in private tutoring scored higher in literacy, numeracy, and total scores. A small Matthew Effect was found as the statistically significant variables used as predictors aligned with socio-economic status. This alignment depicts that the rich become academically richer while the poor become academically poorer. The hybrid public-private education system in Cambodia may be exacerbating inequity for the most marginalized populations.

description: The 7th International Workshop on Theorem proving components for Educational software (ThEdu'18) was held in Oxford, United Kingdom, on 18 July 2018. It was associated to the conference, Federated Logic Conference 2018 (FLoC2018). The major aim of the ThEdu workshop series was to link developers interested in adapting Computer Theorem Proving (TP) to the needs of education and to inform mathematicians and mathematics educators about TP's potential for educational software. Topics of interest include: methods of automated deduction applied to checking students' input; methods of automated deduction applied to prove post-conditions for particular problem solutions; combinations of deduction and computation enabling systems to propose next steps; automated provers specific for dynamic geometry systems; proof and proving in mathematics education. ThEdu'18 was a vibrant workshop, with one invited talk and six contributions. It triggered the post-proceedings at hand.

description: A study of a stable front propagating in a turbulent medium is presented. The front is generated through a reaction-diffusion equation, and the turbulent medium is statistically modeled using a Langevin equation. Numerical simulations indicate the presence of two different dynamical regimes. These regimes appear when the turbulent flow either wrinkles a still rather sharp propagating interfase or broadens it. Specific dependences of the propagating velocities on stirring intensities appropriate to each case are found and fitted when possible according to theoretically predicted laws. Different turbulent spectra are considered.

description: The level of background signals in modern cryogenic resonant mass gravitational wave antenna is discussed caused by (a) the geomagnetic field pulsations and (b) an atmosferic of very low frequency band, generated by a lightning flash. The analysis of our results show that the signals of this origin will generally exceed the signals from the gravitational wave sources. To suppress these artifacts in such gravitational antenna, it is necessary to use the magnetometer included as anti-coincidence protection and a system of magnetic screens.

All these variations were expressed in terms of the perturbed matter energy momentum tensor and the perturbed charge current density. Combining these expressions we reached to the form of the {\it physical version} of the first law of black hole dynamics for the stationary black holes in the considered theory being the strong support for the cosmic censorship.

description: Atlantic Puffins Fratercula arctica and Razorbills Alca torda alter their chick provisioning behaviour when equipped with tracking loggers. To test whether feeding data from global positioning system (GPS) tags in a companion project represented normal behaviour, we examined the effect of externally mounted GPS loggers on parental effort of Atlantic Puffins and Razorbills through chick measurements and video recordings to determine individual responses to tagging. We compared chick growth, nest attendance and provisioning between breeding pairs with and without tagged birds (nest-level), as well as between tagged and untagged mates (mate-level) with the aim of revealing responses of untagged partners to the tagging of their mate. We found all measures of parental effort compared at the nest-level to be similar between nests with one tagged adult and nests without tagged birds. However, video recordings revealed differences in individual behaviour in both species, in which untagged partners spent more time provisioning the chick and also delivered significantly more food to chicks than their tagged partners, though partners shared nest attendance. Behaviours revealed through video recordings showed that the GPS tags introduced bias against detecting where adults forage for their chicks. Future tracking studies should consider measures of tag effect at both the mate- and nest-level as well as the potential bias in the movement data when making biological inferences.

description: We evaluated the effects of abomasal infusion of emulsifiers on fatty acid (FA) digestibility and milk production of lactating dairy cows. All emulsifiers examined were polysorbates, nonionic surfactants, consisting of a polyethoxylated sorbitan esterified with FA. The polysorbates tested in this study consisted of the same polyethoxylated sorbitan base but differed by the FA esterified to it. Eight rumen-cannulated multiparous cows (89 ± 13 days in milk) were assigned to a treatment sequence in 4×4 Latin squares with 18 d periods consisting of 7 d of washout and 11 d of infusion. Treatments were abomasal infusions of water only (CON) or 30 g/d of different emulsifiers: polysorbate-C16:0 (T40), polysorbate-C18:0+C16:0 (T60), and polysorbate-C18:1 (T80). Emulsifiers were dissolved in water and delivered at 6 h intervals (total daily infusion was divided into 4 equal infusions per day). Cows were fed the same diet which contained (% diet dry matter) 32.1% neutral detergent fiber, 15.7% crude protein, 25.8% starch, and 3.32% FA (including 1.92% FA from a saturated FA supplement containing 34.2% C16:0 and 47.7% C18:0). The T80 treatment increased total FA digestibility compared with CON (5.40 percentage-units) and T60 (3.90 percentage-units) and tended to increase it compared with T40. Also, T40 tended to increase and T80 increased (4.80 percentage-units) 16-carbon FA digestibility compared with CON. The T80 treatment increased 18-carbon FA digestibility compared with the other treatments. The T40 treatment tended to increase and T80 increased total FA absorption compared with CON (53 g/d) and T60 (52 g/d). Both T40 and T80 increased the absorption of 16-carbon FA compared with CON and T60. The T60 treatment did not differ from CON for any digestibility variable. Both T40 and T80 increased the yields of milk fat, 3.5% FCM, de novo, mixed and preformed milk FA compared with CON. In conclusion, not all emulsifiers increased FA digestibility. Compared with CON, T80 increased the digestibility and absorption of total, 16 and 18-carbon FA. The T40 treatment tended to increase and T80 increased total FA absorption and the yields of milk fat and 3.5% FCM compared with CON. Milk fat yield was increased by increases in de novo, mixed, and preformed milk FA. In our short-term infusion study, results suggest that the predominant FA present in the polysorbate impacts its ability to improve FA digestibility. Overall, FA digestibility and absorption were improved the most when cows received the T80 treatment.

description: The Ashcroft Quarry Project, located approximately 65 km west of Kamloops in arid sagebrushbunchgrass rangeland, entails the extraction and processing of crushed basaltic tuff for the manufacture of roofing granules. The Mining Lease is on Crown land, within the Agricultural Land Reserve (ALR. The quarry and processing plant are expected to operate at least 50 years and will alienate about 45 ha of high quality rangeland grazed by both cattle and wildlife. Intensive reclamation of the areas of short-terrn disturbance will minimize the loss of range in the nearterm. Final reclamation of the quarry and dump areas will involve the use of both native and agronomic grasses (bunchgrass and annuals), as well as native shrubs and trees. A weed control program, involving the identification and eradication of weed species through mechanical and chemical controls, was initiated in the first year of major site development. This paper provides a brief description of the development and major planning issues, as well as a review of the reclamation objectives and specific practices employed at the site in the first two years of development.

 Culicoides owyheensis Jones and Wirth, 1978: 57 (misspelled as owyheenis; key; female; Idaho). Wirth et al. 1985: 36 (numerical characters; fig. female wing).
 Diagnosis. (Tables 14, 15, 17, 18) Brown with some yellow; wing without pattern of pale spots (as in Fig. 3 C. stonei); two sclerotized ovoid spermathecae and fingerlike vestigial third (as in Fig. 45 C. stonei); posterior portion of female sternite 8 cleft, with blunt submedian posterior projections (as in Fig. 45 C. stonei); ventroposterior membrane of male sternite 9 spiculate; aedeagus Y-shaped, median process stout, short, blunt, half as long as basal arms; parameres separate, simple, apex curved hooklike (as in Fig. 41 C. mortivallis). To distinguish from C. mortivallis, ratios to length of flagellomere 9:>1.50 for flagellomeres 7+8,>3.95 for proboscis,>1.90 for palpal segment 3.
 Distribution. Idaho (Owyhee County), Utah (Grand County).
 Adult behavior. R. H. Jones and H. W. Potter Jr. collected females from the ear of a sheep prostrate with bluetongue in Idaho (Jones and Wirth 1978). However, I think that C. owyheensis may be a junior synonym of C. mortivallis, and the record may be for that species.
 Remarks. Using the measurement ratios from Wirth and Jones (1978: 57), 2 of 17 specimens recognized as either C. owyheensis or C. mortivallis based on SCo pattern were identified as C. owyheensis (Table 18). See also Stonei group discussion.

description: Three-dimensional (3D) structure of a protein is essential as the guidance of structure-based drug dis-covery. To achieve robust homology modeling with atomic-level accuracy, reliable loop predictions are required. Here, a novel hierarchical protocol of Protein Local Optimization Program (PLOP) is designed to produce sub-2 angstrom predictions on loop regions in homology modeling. Dramatic improvements in both speed and accuracy have been realized with implementation of special-designed clustering and adaptive loop closure algorithm. Four prediction rounds are designed for homology modeling as the high-level protocol of PLOP, which allows latter rounds employ the educated guess of backbone atom positions and hydrogen bonding information inherited from the previous rounds, contributing to additional prediction accuracy. The success of PLOP has been demonstrated with four different data sets, mainly concen-trating on homology modeling of H3 loops of antibodies. GPU-accelerated sampling algorithm and deep learning models are implemented, which are able to produce promising predictions as input templates for PLOP in the context of homology modeling.
Investigation of the magnetic ground state of PrRu$_2$Ga$_8$ compound

description: We have investigated the ground state properties of the orthorhombic structure compound PrRu$_2$Ga$_8$ through electronic and magnetic properties studies. The compound crystallizes in the CaCo$_2$Al$_8$-type structure, belonging to space group $Pbam$ (No. 55). The temperature dependence specific heat shows a $λ$-type anomaly at $T_N$ = 3.3 K, indicating a bulk phase transition probably of antiferromagnetic origin. At the Néel temperature $T_N$, the entropy approaches the value of 4.66~J/mol.K which is about 0.8Rln(2), where R is the universal gas constant. The analysis of the low temperature specific heat gives $γ$ = 46 mJ/mol.K$^2$. The temperature dependence DC magnetic susceptibility $χ(T)$ confirms the anomaly at 3.3 K and follows the Curie-Weiss law for temperatures above 50~K, with the calculated effective magnetic moment, $μ_\mathrm{eff}$ = 3.47(2)~$μ_B$/Pr and Weiss temperature $θ_p$ = --7.80(1)~K. This effective magnetic moment value is in good agreement with the Hund$^\prime$s rule theoretical free-ion value of 3.58~$μ_B$ for Pr$^{3+}$. The electrical resistivity data also shows an anomaly at $T_N$ and a broad curvature at intermediate temperatures probably due to crystalline electric field (CEF) effects. The Pr$^{3+}$ in this structure type has a site symmetry of $C_s$ which predicts a CEF splitting of the $J$ = 4 multiplet into 9 singlets and thus rule out in principle the occurrence of spontaneous magnetic order. In this article we discuss the magnetic order in PrRu$_2$Ga$_8$ in line with an induced type of magnetism resulting from the admixture of the lowest CEF level with the first excited state.

description: A class of $ G $-invariant Einstein-Yang-Mills (EYM) systems with cosmological constant on homogeneous spaces $ G / H $, where $ G $ is a semisimple compact Lie group, is presented. These EYM--systems can be obtained in terms of dimensional reduction of pure gravity. If $ G / H $ is a symmetric space, the EYM--system on $ G / H $ provides a static solution of the EYM--equations on spacetime $ {\Bbb R} \times G / H $. This way, in particular, a solution for an arbitrary Lie group $ F $, considered as a symmetric space, is obtained. This solution is discussed in detail for the case $ F = SU(2) $. A known analytical EYM--system on $ {\Bbb R} \times S^3 $ is recovered and it is shown - using a relation to the BPST instanton - that this solution is of sphaleron type. Finally, a relation to the distance of Bures and to parallel transport along mixed states is shown.

Male C. nanellus would most likely be confused with those C. kibunensis that occasionally have five spines in the hind tibial comb; however, C. kibunensis has a more robust aedeagus with thicker basal arms and a broader distal process (Fig. 98). Females are readily distinguished by SCo pattern, antennal ratio, and the distinctive palpal segment 3. No C. nanellus specimens were examined.

description: We study the structure of Abrikosov vortices in two-band superconductors for different external magnetic fields and different parameters of the bands. The vortex core size determined by the coherence lengths are found to have qualitatively different behaviour from that determined by the quasiparticle density of states spatial variation. These different vortex core length scales coincide near the upper critical field, while the discrepancy between them becomes quite significant at lower fields. Within the diffusive approximation we demonstrate several generic regimes in the field dependence of the vortex core sizes determined by the disparity of diffusion constants in the two bands.

description: Controlling large particle systems in collective dynamics by a few agents is a subject of high practical importance, e.g., in evacuation dynamics. In this paper we study an instantaneous control approach to steer an interacting particle system into a certain spatial region by repulsive forces from a few external agents, which might be interpreted as shepherd dogs leading sheep to their home. We introduce an appropriate mathematical model and the corresponding optimization problem. In particular, we are interested in the interaction of numerous particles, which can be approximated by a mean-field equation. Due to the high-dimensional phase space this will require a tailored optimization strategy. The arising control problems are solved using adjoint information to compute the descent directions. Numerical results on the microscopic and the macroscopic level indicate the convergence of optimal controls and optimal states in the mean-field limit,i.e., for an increasing number of particles.

English Essay on the contradictions between "performance" as action and profession and the discursive and social fashion of seeing "performativity" everywhere: If everything is always as a matter of potentiality prone to "perform" professional performers have no function.
The conflict between the single item of "a performance" and the general climate of "performativity" is further explored with 2 "speech acts" (according to John Austin): The formula "I do" spoken at weddings as a readiness to do without doing anything in particular, and the line in the song, as sung in the movie based on the Rocky Opera "Tommy" by "The Who": "I am free". This paradigmatic speech act of autistic son turned messiah appears as its own parody by now. But can still by the power of its own historical contingency proof the superiority of the single act, performance, speech over the "performativity" of over-complex impersonal systems.
Long term vegetation development on reclaimed sites
Creators: name: Polster, D. F.
Publisher: name: The University of British Columbia
Year: 2009

description: Successional change that leads to the development of stable long lived ecosystems on reclaimed lands is encouraged through the process of successional reclamation. Recognition of reclamation as a long term process on drastically disturbed sites can assist in defining reclamation goals and objectives that can be reasonably achieved in human time frames. The development of vegetation covers that assist in amelioration of adverse site conditions and that encourage natural successional processes can provide a first step in the reclamation process. Pioneering vegetation can improve soil organic matter content, nutrient levels, moisture holding capacity and soil structure. Key elements for successful development of pioneering vegetation include stabilization of unstable sites, control of erosion and an open cover into which native species can invade. This paper explores the steps that can be used to assist natural successional processes in the development of successionally appropriate vegetation on disturbed sites and the development of that vegetation over the long term. Inferences about the future direction of vegetation development are proposed. Examples, including sites where soil bioengineering has been used as a first step in the revegetation process, are drawn from the author's experience.
MCTS-based Automated Negotiation Agent (Extended Abstract)

description: This paper introduces a new Negotiating Agent for automated negotiation on continuous domains and without considering a specified deadline. The agent bidding strategy relies on Monte Carlo Tree Search, which is a trendy method since it has been used with success on games with high branching factor such as Go. It uses two opponent modeling techniques for its bidding strategy and its utility: Gaussian process regression and Bayesian learning. Evaluation is done by confronting the existing agents that are able to negotiate in such context: Random Walker, Tit-for-tat and Nice Tit-for-Tat. None of those agents succeeds in beating our agent; moreover the modular and adaptive nature of our approach is a huge advantage when it comes to optimize it in specific applicative contexts.

description: Yang-Mills gauge theory models on a cylinder coupled to external matter charges provide powerful means to find and solve certain non-linear integrable systems. We show that, depending on the choice of gauge group and matter charges, such a Yang-Mills model is equivalent to trigonometric Calogero-Moser systems and certain known spin generalizations thereof. Choosing a more general ansatz for the matter charges allows us to obtain and solve novel integrable systems. The key property we use to prove integrability and to solve these systems is gauge invariance of the corresponding Yang-Mills model.

description: The last decade has witnessed a dramatic growth in passive investing via exchange-traded funds (ETFs). To the extent that the demand for stocks via ETF flows is not related to firm-specific fundamental values, large ETF flows may push the price of the underlying stocks away from their fundamentals-based value. In this study I provide evidence consistent with this conjecture. In particular, I first document a positive association between ETF flows and the price-to-fundamentals relation of underlying stocks. Then, by using BlackRock’s expansion into the ETF business as an exogenous shock, I provide evidence that the association is likely to be causal rather than reflect some form of endogeneity (i.e., ETFs selecting certain stocks). Also, I find that high-flow firms subsequently underperform low-flow firms in operating and stock performance, consistent with the misvaluation being caused by non-fundamental demand shocks. Cross-sectional tests suggest that the ETF-related misvaluation is stronger for stocks with: a less competitive equity market (i.e., with prices more sensitive to demand shocks), lower ownership by active investors, and more costly arbitrage constraints. Finally, I find that high-flow firms exhibit behavior typically associated with perceived overvaluation (e.g., more secondary equity offerings).

description: Brane Gas Cosmology (BGC) is an approach to unifying string theory and cosmology in which matter is described by a gas of strings and branes in a dilaton gravity background. The Universe is assumed to start out with all spatial dimensions compact and small. It has previously been shown that in this context, in the approximation of neglecting inhomogeneities and anisotropies, there is a dynamical mechanism which allows only three spatial dimensions to become large. However, previous studies do not lead to any conclusions concerning the isotropy or anisotropy of these three large spatial dimensions. Here, we generalize the equations of BGC to the anisotropic case, and find that isotropization is a natural consequence of the dynamics.

description: By inserting a SrZrO$_3$ buffer layer between the film and the substrate, we demonstrate a significant reduction of the threading dislocation density with an associated improvement of the electron mobility in La:BaSnO$_3$ films. A room temperature mobility of 140 cm$^2$ V$^{-1}\text{s}^{-1}$ is achieved for 25-nm-thick films without any post-growth treatment. The density of threading dislocations is only $4.9\times 10^{9}$ cm$^{-2}$ for buffered films prepared on (110) TbScO$_3$ substrates by pulsed laser deposition.

description: Building on recent work of Robertson and Steger, we associate a C*-algebra to a combinatorial object which may be thought of as a higher rank graph. This C*-algebra is shown to be isomorphic to that of the associated path groupoid. Sufficient conditions on the higher rank graph are found for the associated C*-algebra to be simple, purely infinite and AF. Results concerning the structure of crossed products by certain natural actions of discrete groups are obtained; a technique for constructing rank 2 graphs from ``commuting'' rank 1 graphs is given.
