description: The racialized job experiences of Black special educators are often not the dominant narrative when explaining their underrepresentation in the field of special education. Currently, African American teachers make up only 8.5% of the special education teaching staff in U.S. public schools, while African American students comprise 18.5% of students with disabilities served under the Individuals with Disabilities Education Act. Scholars have not focused on the quotidian racial microaggressions that African American prekindergarten through Grade 12 (PK-12) special educators encounter and the impact on their work, recruitment, retention, and underrepresentation. Research has suggested hiring and retaining African American special educators may improve African American student outcomes, by reducing special education disproportionality, high school dropout rates, academic underachievement, underemployment, and incarceration and by improving school performance and graduation rates. This dissertation was a case study in a northeastern major metropolitan city and suburb of 13 Black special educators’ experiences with racial microaggressions, using a framework and methodology of dis/ability critical race studies and Afro pessimism. Three research questions guided this dissertation: What are the racial microaggressions African American special educators report they encounter at their PK-12 schools? How do racial microaggressions affect African American special educators’ classroom teaching, job performance, job satisfaction, and retention? How do African American special educators cope with racial microaggressions at their workplace? Individual interviews indicated all of the Black special educators endured racial microaggressions, and most experienced a coupling of racism and ableism. The study provides evidence that racial and disability microaggressions are a constant occurrence in the work life of Black special educators.

description: The survey description and near-infrared properties for 92 galaxies are presented for the Extended Disc Galaxy Exploration Science (EDGES) Survey, along with an investigation into the properties of the stellar halos of these galaxies. EDGES is a Spitzer Space Telescope Warm Mission program designed to reach the surface brightness limit ($\sim$0.5 kJy sr$^{-1}$ or 29 AB mag arcsec$^{-2}$) of the Infrared Array Camera (IRAC) 3.6 and 4.5 $μ$m bands for a wide range of galaxy types found within the local volume. The surface brightness profiles exhibit a large range in disc scalelength, with breaks more frequently seen than in previous studies, owing in large part to the extremely deep near-infrared imaging. A number of these surface brightness profile breaks may be due to stellar halos, up to 7 galaxies out of the full sample of 92 galaxies, and we explore these implications in relation to current cosmological models. We also report the discovery of a new tidal stream near NGC 3953.

description: A simple spin system is studied as an analog for proteins. We investigate how the introduction of randomness and frustration into the system effects the designability and stability of ground state configurations. We observe that the spin system exhibits protein-like behavior in the vicinity of the transition between ferromagnet and spin glass. Our results illuminate some guiding principles in protein evolution.

description: We confirm the quasi-projective case of Saito's conjecture, namely that the cohomological characteristic classes defined by Abbes and Saito can be computed in terms of the characteristic cycles.
 We construct a cohomological characteristic class supported on the non-acyclicity locus of a separated morphism relatively to a constructible sheaf. As applications of the functorial properties of this class, we prove cohomological analogs of the Milnor formula and the conductor formula for constructible sheaves on (not necessarily smooth) varieties.

description: Tsallis' thermostatistical has received increasing attention due to its success in describing phenomena that manifest unusual thermodynamic properties. In this context, the generalized Saha equation must follow a condition of generalized thermal equilibrium of matter and radiation. The present work aims to explore the non-Gaussian effects on Saha's ionization via Tsallis statistics. To accomplish this, we generalized the number density taking into account a non-Gaussian Fermi-Dirac distribution, and then set out the Saha equation for the cosmological recombination. As a result, we highlight two new non-Gaussian effects: $i$) two generalized chemical equilibrium conditions, one for the relativistic regime and the other for the non-relativistic one; and $ii$) the hydrogen binding $q$-energy. We demonstrated that to yields smooth shifts in the binding energy, the $a$-parameter must be very small. We also showed that binding $q$-energy exhibits symmetrical behavior around the value of the standard binding energy. Besides, we used the $q$-energy in order to access other hydrogen energy levels, and we ascertained the values of the $a$-parameter that access those levels and their relationship to temperature. Finally, we employed these results to examine the non-Gaussian effects of the deuterium bottleneck, recombination and the particle anti-particle excess.

The Accuracy vs. Sampling Overhead Trade-off in Quantum Error Mitigation Using Monte Carlo-Based Channel Inversion

description: Quantum error mitigation (QEM) is a class of promising techniques for reducing the computational error of variational quantum algorithms. In general, the computational error reduction comes at the cost of a sampling overhead due to the variance-boosting effect caused by the channel inversion operation, which ultimately limits the applicability of QEM. Existing sampling overhead analysis of QEM typically assumes exact channel inversion, which is unrealistic in practical scenarios. In this treatise, we consider a practical channel inversion strategy based on Monte Carlo sampling, which introduces additional computational error that in turn may be eliminated at the cost of an extra sampling overhead. In particular, we show that when the computational error is small compared to the dynamic range of the error-free results, it scales with the square root of the number of gates. By contrast, the error exhibits a linear scaling with the number of gates in the absence of QEM under the same assumptions. Hence, the error scaling of QEM remains to be preferable even without the extra sampling overhead. Our analytical results are accompanied by numerical examples.

description: Point-to-Point Shortest Distance (PPSD) query is a crucial primitive in graph database applications. Hub labeling algorithms compute a labeling that converts a PPSD query into a list intersection problem (over a pre-computed indexing) enabling swift query response. However, constructing hub labeling is computationally challenging. Even state-of-the-art parallel algorithms based on Pruned Landmark Labeling (PLL) [3], are plagued by large label size, violation of given network hierarchy, poor scalability and inability to process large graphs. In this paper, we develop novel parallel shared-memory and distributed-memory algorithms for constructing the Canonical Hub Labeling (CHL) that is minimal in size for a given network hierarchy. To the best of our knowledge, none of the existing parallel algorithms guarantee canonical labeling. Our key contribution, the PLaNT algorithm, scales well beyond the limits of current practice by completely avoiding inter-node communication. PLaNT also enables the design of a collaborative label partitioning scheme across multiple nodes for completely in-memory processing of massive graphs whose labels cannot fit on a single machine. Compared to the sequential PLL, we empirically demonstrate upto 47.4x speedup on a 72 thread shared-memory platform. On a 64-node cluster, PLaNT achieves an average 42x speedup over single node execution. Finally, we show how our approach demonstrates superior scalability - we can process 14x larger graphs (in terms of label size) and construct hub labeling orders of magnitude faster compared to state-of-the-art distributed paraPLL algorithm.

description: The development and implementation of a simulation based forest planning model is reported in this document. The model is designed to help a forest manager choose the schedule of harvesting, other silvicultural, and road building activities that maximize the contribution of a forest area to the present net worth of the company managing the area. It is assumed that the forest products company faces rigid mill capacity constraints. The theory of forest rotation is used to identify the costs and benefits of delaying the harvest of forest stand aggregates. In each period, stand aggregates are sorted by descending net cost of delay per cubic metre. Harvest proceeds down this harvest priority list until the volume request for the period is satisfied. Harvested stands are assigned to the management regime that maximizes the present net worth of the next rotation. Stand aggregates in inaccessible areas are not harvested, but the net costs of delaying harvest and regeneration for these aggregates are used to provide the analyst with an indication of priority areas for access development. The analyst chooses a number of roading projects to evaluate for each period: the project where the difference between the costs of delay avoided by harvest and the interest costs of the roading project is the greatest is selected as the best roading project for the period. The model is applied to a forest management licence agreement area in Saskatchewan. The study demonstrates the application of the model to a forest planning problem. The sensitivity of the model to changes in discount rate and period length is examined. The importance of sorting the harvest priority list by net cost of delay per cubic metre and not cost per hectare is demonstrated. The model developed here is useful for forest planning under a wide variety of institutional and market structures realted to the harvesting and processing of wood fibre. A companion document to this report entitled "A Forest Planning Simulation Model: User's Guide" describing the use of the model is available

description: We investigate the distribution of metals in the cosmological volume at $z\sim3$, in particular, provided by massive population III (Pop III) stars using a cosmological $N$-body simulation in which a model of Pop III star formation is implemented. Owing to the simulation, we can choose minihaloes where Pop III star formation occurs at $z>10$ and obtain the spatial distribution of the metals at lower-redshifts. To evaluate the amount of heavy elements provided by Pop III stars, we consider metal yield of pair-instability or core-collapse supernovae (SNe) explosions of massive stars. By comparing our results to the Illustris-1 simulation, we find that heavy elements provided by Pop III stars often dominate those from galaxies in low density regions. The median value of the volume averaged metallicity is $Z\sim 10^{-4.5 - -2} Z_{\odot}$ at the regions. Spectroscopic observations with the next generation telescopes are expected to detect the metals imprinted on quasar spectra.

Efficient Mean-Field Simulation of Quantum Circuits Inspired by Density Functional Theory

description: Exact simulations of quantum circuits (QCs) are currently limited to $\sim$50 qubits because the memory and computational cost required to store the QC wave function scale exponentially with qubit number. Therefore, developing efficient schemes for approximate QC simulations is a current research focus. Here we show simulations of QCs with a method inspired by density functional theory (DFT), a widely used approach to study many-electron systems. Our calculations can predict marginal single-qubit probabilities (SQPs) with over 90% accuracy in several classes of QCs with universal gate sets, using memory and computational resources linear in qubit number despite the formal exponential cost of the SQPs. This is achieved by developing a mean-field description of QCs and formulating optimal single- and two-qubit gate functionals $-$ analogs of exchange-correlation functionals in DFT $-$ to evolve the SQPs without computing the QC wave function. Current limitations and future extensions of this formalism are discussed.

description: Over the past ten years, there have been several initiatives in Malawi to strengthen the processes through which national policies, strategies, and programs in the agriculture sector are designed and approved. These processes define how the nation assures the food security and nutrition of its citizens. As a consequence, in addition to the Ministry of Agriculture, Irrigation, and Water Development (MoAIWD), which continues to coordinate these policy processes, a broader and more diverse range of civil society and non-governmental organizations, firms or representatives of sub-sectoral umbrella organization from the private sector, and agricultural and food policy researchers from various institutions all now engage in the policy processes more regularly. Development partners remain engaged, although more so than in the past their perspectives are now more harmonized through the Donor Committee on Agriculture and Food Security.

description: We examine the origin of neutrino masses and oscillations in the context of the six-dimensional standard model. The space-time symmetries of this model explain proton stability and forbid Majorana neutrino masses. The consistency of the six-dimensional theory requires three right-handed neutrinos, and therefore Dirac neutrino masses are allowed. We employ the idea that the smallness of these masses is due to the propagation of the right-handed neutrinos in a seventh, warped dimension. We argue that this class of theories is free of gravitational anomalies. Although an exponential hierarchy arises between the neutrino masses and the electroweak scale, we find that the mass hierarchy among the three neutrino masses is limited by higher-dimension operators. All current neutrino oscillation data, except for the LSND result, are naturally accommodated by our model. In the case of the solar neutrinos, the model leads to the large mixing angle, MSW solution. The mechanism employed, involving three right-handed neutrinos coupled to a scalar in an extra dimension, may explain the features of the neutrino spectrum in a more general class of theories that forbid Majorana masses.

description: The optical properties of quasi-one-dimensional metallic LaTiO$_{3.41}$ are studied for the polarization along the $a$ and $b$ axes. With decreasing temperature modes appear along both directions suggestive for a phase transition. The broadness of these modes along the conducting axis might be due to the coupling of the phonons to low-energy electronic excitations across an energy gap. We observe a pronounced midinfrared band with a temperature dependence consistent with (interacting) polaron models. The polaronic picture is corroborated by the presence of strong electron-phonon coupling and the temperature dependence of the dc conductivity.

description: An unknotting operation is a local move such that any knot diagram can be transformed into a diagram of the trivial knot by a finite sequence of these operations plus some Reidemeister moves. It is known that for all $n \geq 2$ the $H(n)$-move is an unknotting operation for classical knots and links. In this paper, we extend the classical unknotting operation $H(n)$-move to virtual knots and links. Virtualization and forbidden move are well-known unknotting operations for virtual knots and links. We also show that virtualization and forbidden move can be realized by a finite sequence of generalized Reidemeister moves and $H(n)$-moves.

description: Polymer melts undergoing large deformation by uniaxial elongation are studied by molecular dynamics simulations of bead-spring chains in melts. Applying a primitive path analysis to strongly deformed polymer melts, the role of topological constrains in highly entangled polymer melts is investigated and quantified. We show that the over-all, large scale conformations of the primitive paths (PPs) of stretched chains follow affine deformation while the number and the distribution of entanglement points along the PPs do not. Right after deformation, PPs of chains retract in both directions parallel and perpendicular to the elongation. Upon further relaxation we observe a long-lived clustering of entanglement points. Together with the delayed relaxation time this leads to a metastable inhomogeneous distribution of topological constraints in the melts.

description: Perishbility is a cost-increasing factor common in the marketing of seafood products. Modern preservation techniques, particularly the various modes of freezing, have been highly effective extenders of storage life and have paved the way for universal distribution of the products of many fisheries. Nontheless, problems of quality maintenance persist in the seafood industry and there is ample justification for continued efforts to improve preservation methdods. This is especially true for the shrimp industry which yearly is confrotned by a proportionately small but costly spoilage problem. Irradiation preservation is one of the new methods under study that appears especially suitable for seafood products. As a follow-up to technological research, this study explores the commerical feasibility of using irradiation as a preservation technique for processed shrimp products in the Gulf and South Atlantic States Region. The study finds that the loss rate due to spoilage among processed shrimp products may be as high as 6 percent of total production. This represents at minimum an annual economic loss to distributors in the neighborhood of $16 million. Consumers are heavy losers too, inasmuch as shrimp lost through spoilage reduce supplies and set the state for higher prices. Assuming that irradiation processing could eliminate at least one-half the spoilage problem, commercial investments in shrimp irradiation processing appear highly attractive. The investment, from a social point of view, would likewise be attractive, as ample public benefits would be generated by a relatively modest public expenditure fro research and development of the process. It is also pointed out in the study that there is no certainty at present that shrimp irradiation processing will preform, technologically, in strict accordance with the assumptions made in this economic feasibility analysis. However, the analysis servfes a useful prupose in emphasizng, generally, the economic wisdom of even modest expenditures and efforts to improve the quality of high-valued high-volume seafood products.

description: We study the low energy dynamics of a single Dp-brane carrying sufcient large number of D0-brane charges in type IIA theory. We assume the D-brane topology to be $R \times \mathcal{M}_{2n} $ , where $\mathcal{M}_{2n}$ is a closed manifold admitting a symplectic structure. We propose a new gauge fixing condition which eliminates the spatial gauge fluctuations on the Dp-brane. Using a conventional regularization method, one finds that the dynamics is characterized by D0-brane matrix description when the density of D0-branes is large enough. We also calculate the leading order interactions between two D2-branes carrying both electric and magnetic fluxes in matrix theory.

description: We derive general properties of the scale-dependent effective spectral dimensions of non-perturbative gauge boson propagators as they appear as solutions from different methods in Yang-Mills theories. In the ultraviolet and for short time scales the anomalous dimensions of the propagators lead to a slight decrease of the spectral dimension as compared to the one of a free propagator. Lowering the momentum scale, the spectral dimension decreases further. The class of propagators which display a maximum at Euclidean momenta, and thus violate positivity, always approaches a spectral dimension of one for large times. We also show that the longest time intervals are not related to the deep infrared but to the momentum scale defined by the position of the maximum.

description: To attend to the Vedic rituals like honouring the dead (śrāddha) he settled in the new territory sixty families of citpāvan brāhmaṇ, ‘who were fair skinned, handsome and had beautiful eyes’. The place where they were settled, was at the feet of the Sahyādrī, and was named Cittapōlan (Cipluṇ). Then he brought ten brāhmaṇ families from Trihōtr from among the pañc gauḍ brāhmaṇ, and settled them at Pan̄cakrōśī and Kuśasthaḷ in Goa. These were families of bhārdvaj, kauśik, vats, kaunḍinya, kaśyap, vasiṣṭh, bhārgava, viśvamitr, gautam and atri gōtr, and were settled in Maṭhagrām (Margao), Kuśasthaḷ (Cortalim) and Kardalinagar (Kēḷśī = Quelossim). [SHKG, 123; SHKD, 303] The fourth chapter of SKH named Vividhbrāhmaṇōtpati, elaborates on the settlement of these daśgōtrī (of ten gōtr as above) brāhmaṇ.Of the total sixty six families, ten were of kauśik, vats and kaunḍinyagōtr; these were settled at Kuśasthaḷ and Kēḷśī.Six families each in Loṭli, Kuśasthaḷ, Varēṇya (Verna) and Maṭhagrām. Ten families in Cuḍāmani (Chorao) and eight in Dipāvati (Divar). Twelve in the centre of Goa (Bardez ?) and in its Paṁcakrōśi (Pedne ?). Though SHK does not say it explicitly, it is obvious that the sixty families of daśgōtrī brāhmaṇ brought from Trihōtr and settled in different villages of Goa make up the gauḍ sārasvat brāhmaṇ community.

description: Ultra-wideband (UWB) devices are widely used in indoor localization scenarios. Single-anchor UWB localization shows advantages because of its simple system setup compared to conventional two-way ranging (TWR) and trilateration localization methods. In this work, we focus on single-anchor UWB localization methods that learn statistical features of the channel impulse response (CIR) in different location areas using a Gaussian mixture model (GMM). We show that by learning the joint distributions of the amplitudes of different delay components, we achieve a more accurate location estimate compared to considering each delay bin independently. Moreover, we develop a similarity metric between sets of CIRs. With this set-based similarity metric, we can further improve the estimation performance, compared to treating each snapshot separately. We showcase the advantages of the proposed methods in multiple application scenarios.

description: This report describes use of the Spatial Characterization Tool (SCT) developed by Texas A&M University to analyze the similarity of the climates of research sites in the major wheat production areas in Bolivia- the highland intermountain valleys and the lowland plains- to those of other regions. For highland environments, zones of similarity were only found in scattered regions of Bolivia and Per, and the complex topography of the Andean region and the relatively large SCT grid cells (9km x 9km) hampered climate characterization. For lowland sites, combined results of analyses of the favorable season plus the coolest or driest quarters of the year ( when wheat is actually grown in lowland Bolivia) identifies the environments of adjacent areas of Bolivia, two regions in Brazil, Small regions in Venezuela, plus areas in Mexico, Central America, and Africa as similar to those in the target sites in Bolivia. Site similarity analysis appears to be a valuable method for understanding relations among crop production environments, allowing prediction of crop responses to agronomic practices, assessments of genetic diversity or sustainability, and other types of studies. Current applications, however, are limited by a alack of quality data.

description: In many application domains such as medicine, information retrieval, cybersecurity, social media, etc., datasets used for inducing classification models often have an unequal distribution of the instances of each class. This situation, known as imbalanced data classification, causes low predictive performance for the minority class examples. Thus, the prediction model is unreliable although the overall model accuracy can be acceptable. Oversampling and undersampling techniques are well-known strategies to deal with this problem by balancing the number of examples of each class. However, their effectiveness depends on several factors mainly related to data intrinsic characteristics, such as imbalance ratio, dataset size and dimensionality, overlapping between classes or borderline examples. In this work, the impact of these factors is analyzed through a comprehensive comparative study involving 40 datasets from different application areas. The objective is to obtain models for automatic selection of the best resampling strategy for any dataset based on its characteristics. These models allow us to check several factors simultaneously considering a wide range of values since they are induced from very varied datasets that cover a broad spectrum of conditions. This differs from most studies that focus on the individual analysis of the characteristics or cover a small range of values. In addition, the study encompasses both basic and advanced resampling strategies that are evaluated by means of eight different performance metrics, including new measures specifically designed for imbalanced data classification. The general nature of the proposal allows the choice of the most appropriate method regardless of the domain, avoiding the search for special purpose techniques that could be valid for the target data.

description: We study the problem of learning good heuristic functions for classical planning tasks with neural networks based on samples represented by states with their cost-to-goal estimates. The heuristic function is learned for a state space and goal condition with the number of samples limited to a fraction of the size of the state space, and must generalize well for all states of the state space with the same goal condition. Our main goal is to better understand the influence of sample generation strategies on the performance of a greedy best-first heuristic search (GBFS) guided by a learned heuristic function. In a set of controlled experiments, we find that two main factors determine the quality of the learned heuristic: the algorithm used to generate the sample set and how close the sample estimates to the perfect cost-to-goal are. These two factors are dependent: having perfect cost-to-goal estimates is insufficient if the samples are not well distributed across the state space. We also study other effects, such as adding samples with high-value estimates. Based on our findings, we propose practical strategies to improve the quality of learned heuristics: three strategies that aim to generate more representative states and two strategies that improve the cost-to-goal estimates. Our practical strategies result in a learned heuristic that, when guiding a GBFS algorithm, increases by more than 30% the mean coverage compared to a baseline learned heuristic.

Dynamics of a noninteracting colloidal fluid in a quenched Gaussian random potential: A time-reversal-symmetry-preserving field-theoretic approach

description: We develop a field-theoretic perturbation method preserving the fluctuation-dissipation relation (FDR) for the dynamics of the density fluctuations of a noninteracting colloidal gas plunged in a quenched Gaussian random field. It is based on an expansion about the Brownian noninteracting gas and can be considered and justified as a low-disorder or high-temperature expansion. The first-order bare theory yields the same memory integral as the mode-coupling theory (MCT) developed for (ideal) fluids in random environments, apart from the bare nature of the correlation functions involved. It predicts an ergodic dynamical behavior for the relaxation of the density fluctuations, in which the memory kernels and correlation functions develop long-time algebraic tails. A FDR-consistent renormalized theory is also constructed from the bare theory. It is shown to display a dynamic ergodic-nonergodic transition similar to the one predicted by the MCT at the level of the density fluctuations, but, at variance with the MCT, the transition does not fully carry over to the self-diffusion, which always reaches normal diffusive behavior at long time, in agreement with known rigorous results.

description: Using the strong temperature dependent resistance of a normal metal wire in proximity to a superconductor, we have been able to measure the local temperature of electrons heated by flowing a dc current in a metallic wire to within a few tens of millikelvin at low temperatures. By placing two such thermometers at different parts of a sample, we have been able to measure the temperature difference induced by a dc current flowing in the sample. This technique may provide a flexible means of making quantitative thermal and thermoelectric measurements on mesoscopic metallic samples.
An Economic Evaluation of Columbia River Anadromous Fish Programs

description: It is Important to avoid misallocation of resources for either private or public production.. Misallocation in public programs can result frym failure to employ resources in high priority uses or to eliminate programs that have become obsolete. This study evaluates the benefits and costs of the continuing public program aimed at maintaining Columbia River anadi.omous fish runs. The hydroelectric power potential of the Columbia River exceeds that of all other United States river basins. Irrigation, flood control navigation and recreation are other important products that. are, often complementary with dam construction. Anadromous fish, however, compete with products requiring construction of dams that blockade essential fish migration routes. Costly passage facilities at the dams prevent total blockage of the lower river and supplemental projects such as fish hatcheries at least partially repilace lost productivity. Benefits from the available supply of Columbia River anad- ., romous fish result from commercial, sport and Indian fishing. These beneff:ts cannot be directly measured through market prices, however, and thus must be estimated. The coEj, of regulated inefficiency was used to estimate net benefits from commercially-caught fish. Regulated inefficiency results from. management policies that equate physical supply capability with market demand through regulated increases in fishing costs. Transfer costs were used as a proxy for nonexistent market prices to estimate the value of sport-caught fish. Revenue maximization using this estimating method implies that some sport fishermen will be excluded. Thus, an assumed transfer from sport to commercial catch was also taken into account. Past, present and future program costs and associated benefits indicate that the effort to preserve Columbia River anadromous fish probably could not have been justified by economic criteria in the 1930's when major costs first began. However, the share of this prograin remaining in 1965 could be justified on economic grounds if traditional capital costs were used and where alternative investment possibilities were not considered.
