description: Solving a system of polynomial equations is a ubiquitous problem in the applications of mathematics. Until recently, it has been hopeless to find explicit solutions to such systems, and mathematics has instead developed deep and powerful theories about the solutions to polynomial equations. Enumerative Geometry is concerned with counting the number of solutions when the polynomials come from a geometric situation and Intersection Theory gives methods to accomplish the enumeration. We use Macaulay 2 to investigate some problems from enumerative geometry, illustrating some applications of symbolic computation to this important problem of solving systems of polynomial equations. Besides enumerating solutions to the resulting polynomial systems, which include overdetermined, deficient, and improper systems, we address the important question of real solutions to these geometric problems. The text contains evaluated Macaulay 2 code to illuminate the discussion. This is a chapter in the forthcoming book "Computations in Algebraic Geometry with Macaulay 2", edited by D. Eisenbud, D. Grayson, M. Stillman, and B. Sturmfels. While this chapter is largely expository, the results in the last section concerning lines tangent to quadrics are new.

description: Visual problem solving with multiple representations is a critical component of chemistry learning and communication. Understanding how students comprehend and utilize visual representations is key to improving chemistry education, and a multimodal approach to understanding how students tackle visual stoichiometry problems offers insight into misconceptions and difficulties that they face. A mixed methods approach was used, employing multimodal data (eye-tracking, drawings, oral responses, and visual problem solving scores) to study participant interaction with representations and develop a framework for understanding college general chemistry students' metavisualization skills. Student performance during a PhET interactive simulation chemistry game was investigated using eye-tracking and qualitative analyses of a talk aloud protocol to isolate key mental blocks contributing to the participants' misconceptions. Cluster analysis and principal component analysis of gaze patterns revealed that participants follow coherent patterns when solving visual problems with multiple representations with respect to the equation, submicroscopic representations, and numbers provided in the question. Participants were divided into high and low score groups based on quantitative analysis of responses to key questions associated with the conservation of mass in stoichiometric analysis and the groups were further investigated using the of multimodal responses from individuals within each group. Eye-tracking and cluster analysis were found to be valuable tools for framing how students solve chemistry problems with multiple representations.

description: We demonstrate four novel multimodal methods for efficient video summarization and comprehensive cross-cultural news video understanding.
      First, For video quick browsing, we demonstrate a multimedia event recounting system. Based on nine people-oriented design principles, it summarizes YouTube-like videos into short visual segments (812sec) and textual words (less than 10 terms). In the 2013 Trecvid Multimedia Event Recounting competition, this system placed first in recognition time efficiency, while remaining above average in description accuracy.
      Secondly, we demonstrate the summarization of large amounts of online international news videos. In order to understand an international event such as Ebola virus, AirAsia Flight 8501 and Zika virus comprehensively, we present a novel and efficient constrained tensor factorization algorithm that first represents a video archive of multimedia news stories concerning a news event as a sparse tensor of order 4. The dimensions correspond to extracted visual memes, verbal tags, time periods, and cultures. The iterative algorithm approximately but accurately extracts coherent quad-clusters, each of which represents a significant summary of an important independent aspect of the news event. We give examples of quad-clusters extracted from tensors with at least 108 entries derived from international news coverage. We show the method is fast, can be tuned to give preferences to any subset of its four dimensions, and exceeds three existing methods in performance.
      Thirdly, noting that the co-occurrence of visual memes and tags in our summarization result is sparse, we show how to model cross-cultural visual meme influence based on normalized PageRank, which more accurately captures the rates at which visual memes are reposted in a specified time period in a specified culture.
      Lastly, we establish the correspondences of videos and text descriptions in different cultures by reliable visual cues, detect culture-specific tags for visual memes and then annotate videos in a cultural settings. Starting with any video with less text or no text in one culture (say, US), we select candidate annotations in the text of another culture (say, China) to annotate US video. Through analyzing the similarity of images annotated by those candidates, we can derive a set of proper tags from the viewpoints of another culture (China). We illustrate cultural-based annotation examples by segments of international news. We evaluate the generated tags by cross-cultural tag frequency, tag precision, and user studies.

description: Causal inference from observational data is a vital problem, but it comes with strong assumptions. Most methods assume that we observe all confounders, variables that affect both the cause variables and the outcome variables. But whether we have observed all confounders is a famously untestable assumption. In this dissertation, we develop algorithms for causal inference from observational data, allowing for unobserved confounding. These algorithms focus on problems of multiple causal inference: scientific studies that involve many causes or many outcomes that are simultaneously of interest. Begin with multiple causal inference with many causes. We develop the deconfounder, an algorithm that accommodates unobserved confounding by leveraging the multiplicity of the causes. How does the deconfounder work? The deconfounder uses the correlation among the multiple causes as evidence for unobserved confounders, combining Bayesian factor models and predictive model checking to perform causal inference. We study the theoretical requirements for the deconfounder to provide unbiased causal estimates, along with its limitations and trade-offs. We also show how the deconfounder connects to the proxy-variable strategy for causal identification (Miao et al., 2018) by treating subsets of causes as proxies of the unobserved confounder. We demonstrate the deconfounder in simulation studies and real-world data. As an application, we develop the deconfounded recommender, a variant of the deconfounder tailored to causal inference on recommender systems. Finally, we consider multiple causal inference with many outcomes. We develop the control-outcome deconfounder, an algorithm that corrects for unobserved confounders using multiple negative control outcomes. Negative control outcomes are outcome variables for which the cause is a priori known to have no effect. The control-outcome deconfounder uses the correlation among these outcomes as evidence for unobserved confounders. We discuss the theoretical and empirical properties of the control-outcome deconfounder. We also show how the control-outcome deconfounder generalizes the method of synthetic controls (Abadie et al., 2010, 2015; Abadie and Gardeazabal, 2003), expanding its scope to nonlinear settings and non-panel data.
Lewes in the Boer War, 1899-1902

description: The paper takes Lewes as a microcosm for a study of British involvement in and attitudes towards the Boer War. The population was notably patriotic and social occasions such as smoking concerts and rejoicings to mark victories became an important feature of Lewes' social life. A Roll records 214 Lewesians as having served in the War. Of these, volunteers (some of whom had been members of local Volunteer units before the War) had most publicity, but almost certainly 'regulars ' were more numerous. The local papers printed many informative (and uncensored) letters from local men serving in South Africa. Jn many ways the War was perceived as a sum of individual patriotic enterprises rather than as an instance of a state at war. The letters of Trooper B. Moore, which show some disillusionment in the face of hardships and disappointments, illustrate the attitudes of a volunteer. Nine Lewesians died through sickness and three were killed in action (but it is difficult to draw lines in attributing death to service). Participation was also financial; there were many charitable appeals. The Sussex Volunteers Equipment Fund purchased life insurances to cover volunteers and made a grant to the wife of a volunteer to compensate for lost pay. Criticism of the War was expressed at an early stage by Quakers. Critics ('Pro-Boers ') had to face local unpopularity, extending to protest by 'Rough Music' demonstrations. From the summer of 1901 more doubts were expressed and conversions were made to the ranks of the critics.
Multiphase Microfluidics for Convective Heat Transfer and Manufacturing

description: Due to the length scales in microfluidic systems interfacial forces dominate over inertia and gravity. In this work, I have designed, fabricated and studied several systems that manipulate interfacial forces for manufacturing and enhance convective heat transfer. These systems have application in drug delivery, biological and chemical micro-reactors, and electronics cooling. First, fluid-fluid interfaces can be used for the generation of particles. At the interface between two fluids in motion, instabilities can occur. One reason for these instabilities is the difference in shear velocities which causes waves to propagate at the interface. With the correct geometric configuration this phenomena will lead to droplet break up. Second, liquid-gas interfaces can enhance heat and mass transfer. If air bubbles, larger than the channel diameter, are confined to a liquid filled microfluidic channel they will elongate into plugs. These plugs are surrounded by a thin liquid film, which causes the bubbles to faster than the liquid creating a recirculating wake behind the bubble. This can be used to enhance mixing in the channel but it can also increase the heat and mass transfer between the liquid and channel wall. Third, solid-liquid interfaces can enhance and control boiling. In nucleate pool boiling, single bubbles form and depart from the wall. The frequency and size of the bubbles at departure can be influenced by the surface wettability. By patterning surfaces with wetting and non-wetting regions the growth of bubbles can be controlled to enhance the heat transfer.

description: Detecting the thermal and non-thermal emission from the shocked cosmic gas surrounding large-scale structures represents a challenge for observations, as well as a unique window into the physics of the warm-hot intergalactic medium. In this work, we present synthetic radio and X-ray surveys of large cosmological simulations in order to assess the chances of jointly detecting the cosmic web in both frequency ranges. We then propose best observing strategies tailored for existing (LOFAR, MWA and XMM) or future instruments (SKA-LOW and SKA-MID, ATHENA and eROSITA). We find that the most promising targets are the extreme peripheries of galaxy clusters in an early merging stage, where the merger causes the fast compression of warm-hot gas onto the virial region. By taking advantage of a detection in the radio band, future deep X-ray observations will probe this gas in emission, and help us to study plasma conditions in the dynamic warm-hot intergalactic medium with unprecedented detail.

Year: 2024

description: The science methods course model presented here, called an immersed methods course (IMC), engaged preservice elementary teachers in reform‐based science instructional approaches within authentic classroom settings and with elementary students in a guided format. Questions guiding the study were: (1) Did participation in the IMC model impact preservice teachers (PTs') science teaching self‐efficacy? (2) Which science methods course model activities/experiences did PTs identify as the most impactful on their science teaching? (3) How did participation in the IMC model impact PTs' understandings of science teaching? Participants were 138 elementary PTs from a Southeastern United States university. Data were collected from seven course sections over 3 years and included pre/post science teaching self‐efficacy survey data, post written responses, and interviews. Member checking approaches were also used to refine and establish the validity of findings. Researchers completed qualitative data analysis, which was complimented by quantitative statistical analysis. Findings across data sources suggest participation positively influenced PTs' science teaching self‐efficacy and beliefs about the effectiveness of the instructional approaches. Participation also helped PTs apply theories to practice and develop competency using the practices. Findings highlight how the IMC model mitigates constraints associated with current science teacher preparation approaches.

description: We study, from theoretical and phenomenological angles, the Higgs boson oblique parameter $\hat{H}$, as the hallmark of off-shell Higgs physics. $\hat{H}$ is defined as the Wilson coefficient of the sole dimension-6 operator that modifies the Higgs boson propagator, within a Universal EFT. Theoretically, we describe self-consistency conditions on Wilson coefficients, derived from the Källén-Lehmann representation. Phenomenologically, we demonstrate that the process $gg\to h^\ast \to VV$ is insensitive to propagator corrections from $\hat{H}$, and instead advertise four-top production as an effective high-energy probe of off-shell Higgs behaviour, crucial to break flat directions in the EFT.

description: This thesis presents the first systematic study of multimode external kink structure and dynamics in a tokamak using a high-resolution magnetic sensor set.  Multimode effects are directly measured, rather than inferred from anomalies in single-mode behavior.  In order to accomplish this, an extensive set of 216 poloidal and radial magnetic field sensors has been installed in the High Beta Tokamak -- Extended Pulse (HBT-EP) device for high-resolution measurements of three-dimensional mode activity.  An analysis technique known as biorthogonal decomposition (BD) is described, and simulations are presented to justify its use for studying kink mode dynamics in HBT-EP data.  Coherent activity of multiple simultaneous modes is observed using the BD without needing to define a mode structure basis beforehand.  Poloidal mode numbers up to m=8 are observed via sensor arrays with full 360 degree coverage.  Higher poloidal mode numbers are suggested by the data, but cannot be well-resolved with the available diagnostics.  Toroidal mode numbers up to n=4 are observed.  Non-rigid, multimode activity is observed for coexisting external kinks having m/n=3/1 and 6/2 structures.  Despite sharing the same helicity and same resonant surface, rotation of 6/2 modes is independent of 3/1 mode rotation -- the n=2 mode does not simply rotate with double the frequency of the n=1 mode.  During periods of 3/1-dominated activity, the 6/2 mode is observed to modulate the 3/1 amplitude, and in brief instances can overpower the 3/1.  Statistical analysis over many shots reveals the multimode nature of the 3/1 kink to be more significant when the resonant q=3 surface begins internal, then is ejected from the plasma.  This inference is based on the relative amplitudes of secondary modes during 3/1-dominated activity, as well as spectral content of the modes.  Conformal conducting wall segments were also retracted away from the plasma surface using low-order poloidal and toroidal asymmetries to excite measurable differences in low m- and n-number modes.  Kink mode amplitudes increase as the wall segments are withdrawn, and non-symmetric wall configurations modulate the amplitude and frequency of the rotating modes depending upon their toroidal orientation with respect to the non-symmetric wall. Modulations of mode amplitude and rotation are larger for the toroidal wall asymmetry than for the poloidal wall asymmetry.

description: The paper concerns the $q$-state Potts model (i.e., with spin values in $\{1,\dots,q\}$) on a Cayley tree $\mathbb{T}^k$ of degree $k\geq 2$ (i.e., with $k+1$ edges emanating from each vertex) in an external (possibly random) field. We construct the so-called splitting Gibbs measures (SGM) using generalized boundary conditions on a sequence of expanding balls, subject to a suitable compatibility criterion. Hence, the problem of existence/uniqueness of SGM is reduced to solvability of the corresponding functional equation on the tree. In particular, we introduce the notion of translation-invariant SGMs and prove a novel criterion of translation invariance. Assuming a ferromagnetic nearest-neighbour spin-spin interaction, we obtain various sufficient conditions for uniqueness. For a model with constant external field, we provide in-depth analysis of uniqueness vs.\ non-uniqueness in the subclass of completely homogeneous SGMs by identifying the phase diagrams on the "temperature--field" plane for different values of the parameters $q$ and $k$. In a few particular cases (e.g., $q=2$ or $k=2$), the maximal number of completely homogeneous SGMs in this model is shown to be $2^q-1$, and we make a conjecture (supported by computer calculations) that this bound is valid for all $q\ge 2$ and $k\ge2$.

description: Sussex Archaeological Collections, 117, 173-184
description: William Bullaker is important as the author of the first English grammar, and as a tireless advocate of spelling reform in a number of works written in his own phonetic system at the end of the sixteenth century. His literary input has been much studied recently, notably by the School of English at the University of Leeds in the 1960s. This paper is an attempt at writing a biography of Bullaker based on the evidence of his own writings and surviving documentary material. Four main sources have been used. The evidence in the Petworth inclosure dispute proves for the first time that Bullaker received his education in Petworth, and identifies the source of his spelling and pronunciation. The election dispute in Chichester in 1586 shows Bullaker as one of the leaders of the radical group in the city prepared to oppose the Mayor and Corporation. Bullaker's poems and introductions to his own works give information about his military service, his study of civil law and his educational interests, as well as giving glimpses of his personal delight in nature. Finally, the harassment that he and his family received on account of their persistent catholic recusancy, enables a fairly detailed account of the whereabouts and movements of the Bullaker family to be constructed from the papers of the ecclesiastical courts in Chichester.

description: The term meta-analysis refers to the quantitative process of statistically combining results of studies in order to draw overall trends found in a research literature. This technique has become the preferred form of systematic review in fields such as social science and education. As the method has become more standard, the number of large meta-analyses has expanded in these fields as well. Accordingly, the purpose of meta-analysis has expanded to explaining the variation of effect sizes across studies using meta-regression. Unfortunately, missing data is a common problem in meta-analysis. Particularly in meta-regression, missing data problems are frequently related to missing covariates. When not handled properly, missing covariates in meta-regression can impact the precision of statistical inferences and thus the precision of systematic reviews. Ad hoc methods such as complete-case analysis and shifting units of analysis are the most common approaches to address missing data in meta-analysis. These techniques, to some extent, ignore missing values which in turn can lead to biased estimates. The use of model-based methods for missing data are more justifiable than ad hoc approaches. However, its application in meta-analysis is very limited. Multiple imputation is one of these approaches. Its precision relies mainly on how missing values are imputed. Standard multiple imputation approaches do not consider imputations that are compatible with meta-regression and thus can still yield biased estimates. This dissertation addresses these issues by firstly assessing the performance of standard multiple imputation methods in the meta-regression context through a simulation study. To later develop compatible multiple imputations that accommodate features of meta-regression assuming dependent effect sizes. Results show that even though multiple imputation methods can accurately estimate missing data in meta-regression, its accuracy decreases with larger missingness rates and when missingness is strongly related to effect sizes. This study also revealed that, in general, the developed compatible multiple imputation method outperforms standard multiple imputations. These findings also hold for cases in which missingness in a covariate is highly related to the effect size estimates. Finally, an algorithm that allows practitioners to apply compatible imputations in meta-regression was implemented using the R software language.
Multiple Dirichlet Series for Affine Weyl Groups

description: Let W be the Weyl group of a simply-laced affine Kac-Moody Lie group, excepting type A affine root systems of even rank. We construct a multiple Dirichlet series Z(x_1, ... x_n+1 meromorphic in a half-space, satisfying a group W of functional equations. This series is analogous to the multiple Dirichlet series for classical Weyl groups constructed by Brubaker-Bump-Friedberg, Chinta-Gunnells, and others. It is completely characterized by four natural axioms concerning its coefficients, axioms which come from the geometry of parameter spaces of hyperelliptic curves. The series constructed this way is optimal for computing moments of character sums and L-functions, including the fourth moment of quadratic L-functions at the central point via affine D4 and the second moment weighted by the number of divisors of the conductor via affine A_3. We also give evidence to suggest that this series appears as a first Fourier-Whittaker coefficient in an Eisenstein series on the twofold metaplectic cover of the relevant Kac-Moody group. The construction is limited to the rational function field, but it also describes the p-part of the multiple Dirichlet series over an arbitrary global field.

description: The zero curvature representation for two dimensional integrable models is generalized to spacetimes of dimension d+1 by the introduction of a d-form connection. The new generalized zero curvature conditions can be used to represent the equations of motion of some relativistic invariant field theories of physical interest in 2+1 dimensions (BF theories, Chern-Simons, 2+1 gravity and the CP^1 model) and 3+1 dimensions (self-dual Yang-Mills theory and the Bogomolny equations). Our approach leads to new methods of constructing conserved currents and solutions. In a submodel of the 2+1 dimensional CP^1 model, we explicitly construct an infinite number of previously unknown nontrivial conserved currents. For each positive integer spin representation of sl(2) we construct 2j+1 conserved currents leading to 2j+1 Lorentz scalar charges.

description: The Fermilab accelerator complex delivers intense high-energy proton beams to a variety of fixed-target scientific programs, including a flagship long-baseline neutrino program. With the advent of the Deep Underground Neutrino Experiment (DUNE) and Long Baseline Neutrino Facility (LBNF) program there is strong motivation for a 2.4 MW beam power upgrade of the Fermilab proton facility. We show the Fermilab proton facility can achieve 2.4~MW with a new rapid-cycling synchrotron (RCS) to replace the Fermilab Booster and we provide a comprehensive technical analysis of the RCS-based facility design. Past design efforts and operational experience at the Fermilab Booster, J-PARC RCS, and Oak Ridge SNS are leveraged to provide strong empirical precedent for the design. We provide a parametric study of slip-stacking accumulation, RCS extraction energy, space-charge limits, beampipe aperture, eddy current heating, injection foil heating, and lattice optics. The 2.4 MW benchmark for the long baseline neutrino program is achieved independently of a previously proposed multi-GeV linac program, but we assess the impact the linac upgrade would have on RCS performance.

description: Research on mental health outcomes among racial-ethnic, sexual, and gender minority young people indicates that they may be at increased risk for service use disparities when these identity statuses intersect. However, evidence of how having multiple minority identities is related to using mental health services is lacking. This dissertation used a mixed-methods, convergent design to explore and describe relationships between intersecting minority identities and mental health service use in the experiences of 31 Black and Hispanic, sexual and gender minority young adults. Consistent with an intersectional perspective, findings indicated that mental health service use was more strongly associated with minority identities collectively than with any single minority identity, and that experiences of intersecting minority identities could facilitate, as well as hinder, mental health service use among participants. A theoretical model was revealed in which participants negotiated multiple minority identities within four dimensions related to their service use: ethnic-racial culture, intersecting identities, family, and personal identities. Results suggested provider strategies that support intersecting minority identity strengths around culture, community belonging, and self-efficacy may encourage service use and engagement with treatment.

description: Various kinetic Monte Carlo algorithms become inefficient when some of the population sizes in a system are large, which gives rise to a large number of reaction events per unit time. Here, we present a new acceleration algorithm based on adaptive and heterogeneous scaling of reaction rates and stoichiometric coefficients. The algorithm is conceptually related to the commonly used idea of accelerating a stochastic simulation by considering a sub-volume $λΩ$ ($0

description: We give the definition and explore the algebraic structure of a class of quantum symmetries, called topological symmetries, which are generalizations of supersymmetry in the sense that they involve topological invariants similar to the Witten index. A topological symmetry (TS) is specified by an integer n>1, which determines its grading properties, and an n-tuple of positive integers (m_1,m_2,...,m_n). We identify the algebras of supersymmetry, p=2 parasupersymmetry, and fractional supersymmetry of order n with those of the Z_2-graded TS of type (1,1), Z_2-graded TS of type (2,1), and Z_n-graded TS of type (1,1,...,1), respectively. We also comment on the mathematical interpretation of the topological invariants associated with the Z_n-graded TS of type (1,1,...,1). For n=2, the invariant is the Witten index which can be identified with the analytic index of a Fredholm operator. For n>2, there are n independent integer-valued invariants. These can be related to differences of the dimension of the kernels of various products of n operators satisfying certain conditions.

Year: 1985
Subjects: subject: 58

description: Der Steppen-Salbei (Salvia nemorosa L.) ist durch seine lebhaft violetten Hochblätter, die fehlende Grundblattrosette und die grauflaumigen Blätter leicht von den anderen Salbeiarten Mitteleuropas zu unterscheiden. Uber seine Verbreitung, vor allem aber über seine Ökologie und Soziologie ist nur wenig bekannt, aus Deutschland und Österreich sind mit Ausnahme einer Stetigkeitstabelle von FORSTNER (1983) keine Vegetationsaufnahmen publiziert. Deshalb sollen an dieser Stelle eigene Beobachtungen zusammengestellt und mit Literaturangaben verglichen werden.

description: The main purpose of this study was to analyze the effective solutions in the field of waste management in municipalities. The statistical population in this survey –based study consisted of the citizens that lived in Orumiyeh city in West Azerbaijan Province. By using Cochran formula, sample size was estimated to include 180 people. The data collection tool was a questionnaire. The reliability coefficient of the questionnaire was obtained by a Cronbach's alpha that turned out to be 0.87. Results showed that a positive and significance relationship exists between the transport collection and landfill management solution, expense management solution, executive management solution, the strategy management system, as well as the importance of waste management. Also in addition, multi regression results shows that about 55.9 percent of the solid waste management system is determined by variables such as collection and transportation of waste and landfill, executive management, costs management, and improvement of the management system of the organization.
A review of the reclamation research program at Teck Cominco’s Sullivan Mine at Kimberley, BC
Creators: name: Przeczek, John
Publisher: name: The University of British Columbia
Year: 2009

description: The Sullivan ore body, a world class iron-lead-zinc sulphide deposit at Kimberley, BC, was discovered in 1892 by prospectors who were initially attracted to the area by previous lead-silver discoveries. Cominco Ltd. acquired the property in 1909 and mining operations began in 1910. Reclamation activities began at the Sullivan mine in the late 1960’s and a research program to convert waste rock dumps and tailing ponds to productive forest and rangeland was initiated in 1972. Initial studies focused on determining how to revegetate waste rock and mill waste. Various studies demonstrated that at least 30 cm of growth medium is required to grow a satisfactory grass dominated plant community and at least 60 cm of growth medium is required where alfalfa is a desired component. They also demonstrated that complex covers that integrate a float rock capillary barrier are effective in reducing the movement of acids, salts and metals into the growth medium. Species screening trials were used to determine which tree and shrub species would have adequate survival and growth rates. Growing season moisture deficit is the most significant limiting factor at the Sullivan Mine and it was necessary to create conditions that were free of vegetation competition before tree and shrub planting efforts were successful.
The Sanitary Battle of Hastings: The 1848 Public Health Act and Local Government Reform

description: Sussex Archaeological Collections, 125, 175-198
description: This article discusses the events which occurred during the attempt to introduce the 1848 Public Health Act into the borough of Hastings. The Act's supporters believed that failure to adopt it would jeopardize the town's reputation as a high-class resort but its opponents, led by Alfred Burton, strove to exempt the township of St. Leonards from the easure on the grounds of expense and of loss of local autonomy. The paper considers the motives of the opposing parties in the struggle and the networks, local and national which were exploited to prosecute it.

description: We report on phase-coherent transport studies of a Bi$_2$O$_2$Se nanoplate and on observation of universal conductance fluctuations and spin-orbit interaction induced reduction in fluctuation amplitude in the nanoplate. Thin-layered Bi$_2$O$_2$Se nanoplates are grown by chemical vapor deposition (CVD) and transport measurements are made on a Hall-bar device fabricated from a CVD-grown nanoplate. The measurements show weak antilocalization at low magnetic fields at low temperatures, as a result of spin-orbit interaction, and a crossover toward weak localization with increasing temperature. Temperature dependences of characteristic transport lengths, such as spin relaxation length, phase coherence length, and mean free path, are extracted from the low-field measurement data. Universal conductance fluctuations are visible in the low-temperature magnetoconductance over a large range of magnetic fields and the phase coherence length extracted from the autocorrelation function is in consistence with the result obtained from the weak localization analysis. More importantly, we find a strong reduction in amplitude of the universal conductance fluctuations and show that the results agree with the analysis assuming strong spin-orbit interaction in the Bi$_2$O$_2$Se nanoplate.
