title: Evaluation of Airborne Lidar to Estimate Tree Height in a Dense Forest Canopy
Creators: name: Mitchum, Jessica
Publisher: name: George Mason University
Year: 2018
Subjects: subject: Lidar
subject: Forestry
subject: Terrain analysis

description: The focus of this research will consider the application of Light detection and ranging (Lidar) to forestry and military terrain analysis. Lidar is a remote sensing technology that uses light in the form of a pulsed laser to measure ranges; it can provide a three dimensional image into structures, providing information extraction opportunities for use in civilian and military settings. Previous forestry Lidar research reports strong correlation and acceptable root mean squared error (RMSE) observations. Much of this research was conducted in simple forest conditions and have not been rigorously assessed in areas of more complex plant morphology. The primary objective of this thesis was to explore the suitability of an airborne, discrete return Lidar dataset to estimate tree heights in a dense, forested environment in Beltsville, MD using commercial software. Linear regression was used to relate field to Lidar tree height data with an R2 correlation of 0.0008. Results comparing the Lidar canopy height model to field data by human interpretation had an R2 correlation of 0.33 and an RMSE of 6.54 meters. The Lidar canopy height models explained little to none of the field-observed tree height variation. These results were unexpected considering previous research, but fall in line with recent discussions and efforts to address the complexities and sources of error associated with relating field data to airborne Lidar in dense forest canopies. Future research should include exploration of different software, recently published standards of government agencies and professional societies, and altering data collection parameters.

description: Using numerical simulations, we examine the dynamics of driven two-dimensional bidisperse disks flowing over quenched disorder. The system exhibits a series of distinct dynamical phases as a function of applied driving force and packing fraction including a phase separated state as well as a smectic state with liquid like or polycrystalline features. At low driving forces, we find a clogged phase with an isotropic density distribution, while at intermediate driving forces the disks separate into bands of high and low density with either liquid like or polycrystalline structure in the high density bands. In addition to the density phase separation, we find that in some cases there is a fractionation of the disk species, particularly when the disk size ratio is large. The species phase separated regimes form a variety of patterns such as large disks separated by chains of smaller disks. Our results show that the formation of laning states can be enhanced by tuning the ratio of disk radius of the two species, due to the clumping of small disks in the interstitial regions between the large disks.

description: A critical review on signatures of Quark-Gluon-Plasma formation is given and the current (1998) experimental status is discussed. After giving an introduction to the properties of QCD matter in both, equilibrium- and non-equilibrium theories, we focus on observables which may yield experimental evidence for QGP formation. For each individual observable the discussion is divided into three sections: first the connection between the respective observable and QGP formation in terms of the underlying theoretical concepts is given, then the relevant experimental results are reviewed and finally the current status concerning the interpretation of both, theory and experiment, is discussed. A comprehensive summary including an outlook towards RHIC is given in the final section.

Quantum mechanical counterpart of nonlinear optics

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Raman-type laser excitation of a trapped atom allows one to realize the quantum mechanical counterpart of phenomena of nonlinear optics, such as Kerr-type nonlinearities, parametric amplification, and multi-mode mixing. Additionally, huge nonlinearities emerge from the interference of the atomic wave function with the laser waves. They lead to a partitioning of the phase space accompanied by a significantly different action of the time evolution in neighboring phase-space zones. For example, a nonlinearly modified coherent "displacement" of the motional quantum state may induce strong amplitude squeezing and quantum interferences.

description: ‘Overviews of systematic reviews’ collate, appraise and synthesise evidence from systematic reviews (SRs) and meta-analyses. Overviews have evolved in response to the growing number of SRs. This thesis advances methods research in overviews by making them easier to retrieve, outlining a comprehensive list of methods used in overviews, identifying studies evaluating methods, and providing an assessment of the reporting of methods to determine areas of improvement. A major finding is that overviews contain unique challenges and gaps in methods evaluations exist. Methods without evaluation may be used inappropriately and may impact on the validity and reliability of the overview findings.

description: High-level transformation languages like Rascal include expressive features for manipulating large abstract syntax trees: first-class traversals, expressive pattern matching, backtracking and generalized iterators. We present the design and implementation of an abstract interpretation tool, Rabit, for verifying inductive type and shape properties for transformations written in such languages. We describe how to perform abstract interpretation based on operational semantics, specifically focusing on the challenges arising when analyzing the expressive traversals and pattern matching. Finally, we evaluate Rabit on a series of transformations (normalization, desugaring, refactoring, code generators, type inference, etc.) showing that we can effectively verify stated properties.

description: We propose a method for measuring entangled vibronic quantum states of a trapped atom. It is based on the nonlinear dynamics of the system that appears by resonantly driving a weak electronic transition. The proposed technique allows the direct sampling of a Wigner-function matrix, displaying all knowable information on the quantum correlations of the motional and electronic degrees of freedom of the atom. It opens novel possibilities for testing fundamental predictions of the quantum theory concerning interaction phenomena.

Numerical evidence for the spin-Peierls state in the frustrated quantum antiferromagnet

Publisher: name: arXiv
Year: 1995
Subjects: subject: Condensed Matter (cond-mat)

description: We study the spin-$1\over2$ Heisenberg antiferromagnet with an antiferromagnetic $J_3$ (third nearest neighbor) interaction on a square lattice. We numerically diagonalize this ``$J_1$-$J_3$'' model on clusters up to 32-sites and search for novel ground state properties as the frustration parameter $J_3/J_1$ changes. For ``larger'' $J_3/J_1$ we find enhancement of incommensurate spin order, in agreement with spin-wave, large-$N$ expansions, and other predictions. But for intermediate $J_3/J_1$, the low lying excitation energy spectrum suggests that this incommensurate order is short-range. In the same region, the first excited state has the symmetries of the columnar dimer (spin-Peierls) state. The columnar dimer order parameter suggests the presence of long-range columnar dimer order. Hence, this spin-Peierls state is the best candidate for the ground state of the $J_1$-$J_3$ model in an intermediate $J_3/J_1$ region.

description: Harmonic flow in relativistic heavy-ion collisions is observed in a broad range of rapidities, and the flow at different rapidities is correlated. However, fluctuations lead to a small decorrelation of the harmonic flow magnitudes and flow angles at different rapidities. Using a hydrodynamic model with Glauber Monte Carlo initial conditions we show that the flow angle decorrelation strongly depends on the flow magnitude in the event. We propose observables to measure this effect in experiment.

Spectroscopic imaging shows diverse local defect states between Cr and V, which agree with our first-principle calculations. The unique spectroscopic features of V and Cr dopants provide electronic fingerprints for the co-doped magnetic TI samples with the enhanced quantum anomalous Hall effect. Our results also facilitate the exploration of the underlying mechanism of the enhanced quantum anomalous Hall temperature in Cr/V co-doped TIs.

QCD Corrections to Radiative Upsilon Decays

description: We have calculated the next-to-leading order perturbative QCD corrections to the photon energy spectrum in radiative Upsilon decays. The higher-order corrections significantly modify the shape of the spectrum, in particular at large photon energies, and thereby reduce the discrepancy between experimental data and previous leading-order predictions. The next-to-leading order calculation of the photon energy spectrum allows a more reliable determination of the strong coupling constant from radiative Upsilon decays by restricting the analysis to the region of the energy spectrum that can be described by NLO perturbation theory.

Interface roughness, carrier localization and wave function overlap in $c$-plane InGaN/GaN quantum wells: Interplay of well width, alloy microstructure, structural inhomogeneities and Coulomb effects

description: In this work we present a detailed analysis of the interplay of Coulomb effects and different mechanisms that can lead to carrier localization effects in c-plane InGaN/GaN quantum wells. As mechanisms for carrier localization we consider here effects introduced by random alloy fluctuations as well as structural inhomogeneities such as well width fluctuations. Special attention is paid to the impact of the well width on the results. All calculations have been carried out in the framework of atomistic tight-binding theory. Our theoretical investigations show that independent of the here studied well widths, carrier localization effects due to built-in fields, well width fluctuations and random alloy fluctuations dominate over Coulomb effects in terms of charge density redistributions. However, the situation is less clear cut when the well width fluctuations are absent. For large well width (approx. > 2.5 nm) charge density redistributions are possible but the electronic and optical properties are basically dominated by the spatial out-of plane carrier separation originating from the electrostatic built-in field. The situation changes for lower well width (< 2.5 nm) where the Coulomb effect can lead to significant charge density redistributions and thus might compensate a large fraction of the spatial in-plane wave function separation observed in a single-particle picture. Given that this in-plane separation has been regarded as one of the main drivers behind the green gap problem, our calculations indicate that radiative recombination rates might significantly benefit from a reduced quantum well barrier interface roughness.

description: Recent experiment has observed Feshbach resonances between alkaline and alkaline-earth atoms. These Feshbach resonances are insensitive to the nuclear spin of alkaline-earth atoms. Ultilizing this feature, we propose to take this system as a candidate to perform quantum simulation of the Kondo effect. An alkaline atom can form a molecule with an alkaline-earth atom with different nuclear spins, which plays the role of spin-exchange scattering responsible for the Kondo effect. Furthermore, we point out that the existence of three-body bound state and atom-molecule resonance due to the Efimov effect can enhance this spin-exchange scattering, and therefore enhance the Kondo effect. We discuss this mechanism first with a three-body problem in free space, and then demonstrate that the same mechanism still holds when the alkaline atom is localized by an external trap and becomes an impurity embedded in the alkaline-earth atomic gases.
Reliable Quantum Computers

description: The new field of quantum error correction has developed spectacularly since its origin less than two years ago. Encoded quantum information can be protected from errors that arise due to uncontrolled interactions with the environment. Recovery from errors can work effectively even if occasional mistakes occur during the recovery procedure. Furthermore, encoded quantum information can be processed without serious propagation of errors. Hence, an arbitrarily long quantum computation can be performed reliably, provided that the average probability of error per quantum gate is less than a certain critical value, the accuracy threshold. A quantum computer storing about 10^6 qubits, with a probability of error per quantum gate of order 10^{-6}, would be a formidable factoring engine. Even a smaller, less accurate quantum computer would be able to perform many useful tasks. (This paper is based on a talk presented at the ITP Conference on Quantum Coherence and Decoherence, 15-18 December 1996.)

description: The emission-line dwarf galaxy NGC 3413 is known to host a bright X-ray source near its optical center. The 0.3-10 keV luminosity of this source is estimated to be approximately 10$^{39}$ erg$s^{-1}$ potentially qualifying it as an ultra-luminous X-ray (ULX) source. A recent XMM-Newton observation suggests that the source is not point-like, and instead, is more likely a composite of point-like sources with extended and/or diffuse emission. The spectral and temporal features of the bright region are similar to those associated with the so-called broadened disk state of ULXs. Based on a multi-color blackbody spectral fit, we estimate the mass of the bright source to be in the range 3 - 20M$_{\odot}$. Potential optical counterparts are also explored with the aid of available SDSS and PanStars data.

description: Tetraalkylammonium-based quaternary ammonium ([R4N+][DHP−]; R = Ethyl, Propyl, Butyl) salts were synthesized and subjected to in-depth analysis using NMR, FTIR and TG analysis. Subsequent investigations involved examining their impact on the aggregation patterns of the cationic surfactant Cetyltrimethylammonium bromide (CTAB) through the use of conductometry, fluorescence measurements, and UV-Visible spectroscopy. To gain a deeper understanding of the colloidal behavior of CTAB, the critical micelle concentration (cmc) of the surfactant was determined, both in the absence and presence of the quaternary ammonium salts. The observed variations in cmc values were attributed to structural changes within the surfactant-water mixture, made by the presence of these additives. In addition, the investigations include thermodynamic analysis, with a focus on studying the dependence of the cmc on temperature. The resultant thermodynamic parameters were utilized to elucidate the contributions of [R4N+][DHP−], to the electrostatic and hydrophobic interactions involved in the formation of surfactant micellar aggregates. Furthermore, the study assessed the impact of [R4N+][DHP−], on the surfactant’s antibacterial activity by quantifying the zone of inhibition, against both gram-positive and gram-negative bacterial species.

description: This thesis describes the philosophy, recruitment methods, and intellectual activities of the alt right, a predominantly online culture based on notions of white supremacy and patriarchy. Cyberculture, cyber harassment, right-wing extremist language, dissemination methods, meme culture, and political satire as a form of countercultural protest are key components explored in this study. The ethnographic focus is on three websites: American Renaissance, the Daily Stormer, and Reddit’s most popular Donald Trump supporter subreddit. Data on these sites was collected by navigating and using the sites in a form of digital ethnographic observation. This thesis argues that the differences and similarities between the websites are integral to understanding a movement that is profoundly anti-Semitic, racist, and misogynistic, with the power to incite violent activities. This thesis also analyzes the key difference between different factions of the alt right, specifically the pseudo-intellectual, the profanely humorous, and the politically motivated. This thesis argues that the dissent amongst alt right factions strengthens the alt right by creating more diverse alt right arguments and appealing to a wider audience but also weakens it by diversifying the previously unshakable solidarity of alt right thought.

From the left-right production and decay polar angle asymmetries in leptonic Z decays we measure Ae = 0.1544 +- 0.0060, Amu = 0.142 +- 0.015, and Atau = 0.136 +- 0.015. Combined with our left-right asymmetry measured from hadronic decays, we find Ae = 0.1516 +- 0.0021. Assuming lepton universality, we obtain a combined effective weak mixing angle of sin**2 theta^{eff}_W = 0.23098 +- 0.00026.

description: Millimeter wave signals and large antenna arrays are considered enabling technologies for future 5G networks. Despite their benefits for achieving high data rate communications, their potential advantages for tracking of the location of the user terminals are largely undiscovered. In this paper, we propose a novel support detection-based channel training method for frequency selective millimeter-wave (mm-wave) multiple-input-multiple-output system with lens antenna arrays. We show that accurate position and orientation estimation and tracking is possible using signals from a single transmitter with lens antenna arrays. Particularly, the beamspace channel estimation is formulated as two sparse signal recovery problems in the downlink and uplink for the estimation of angle-of-arrival, angle-of-departure, and time-of-arrival. The proposed method offers a higher sparse detection probability compared to the compressed sensing based solutions. Finally, a joint heuristic beamformer design and user position and orientation tracking approach are proposed based on initial estimation of channel parameters obtained in the training phase.

description: Nontraditional students' enrollment continues to increase, but research into their individual experience and appropriate institutional support resources is still in its infancy. This study explores the lived experiences of nontraditional students who enrolled in a four-year degree program and their underlying motivation to go/ return to college. Through the use of semi-structured interviews, participants shared their stories and perspectives into their experiences returning to/ beginning a four-year degree program. These interviews further highlighted the nuances of the nontraditional student experience and how their programs are impacted by their life decisions, obligations, and outside roles. To analyze the data, a thematic analysis with narrative inquiry undertones was performed. Themes of life events impacting academic trajectory, pursuing and persisting in college boosted personal growth, improving career aspirations and trajectory, personal relationships and their hindrance or support to academic success, and institutional support resources can add to and detract from student success were found and addressed. Findings further highlighted the need for future research into specific nontraditional programs/ cohorts, flexible policies that address the constraints faced, dedicated support services, and who this population is and the experiences they are bringing. This study also serves as a catalyst for reframing and supporting the nontraditional student experience through training, research, and updated campus dynamics that showcase this population in a positive light.
title: We’re the Scapegoat of the 21st Century”: Investigating White Collegiate Perspectives, Histories and Racial Framing During the Trump Era
Creators: name: Buckner, Elexus Iris

Subjects: subject: Mixed-race interview
subject: College-educated whites
subject: White racial identity
subject: Racial history

description: The civil rights movements of the 60s and 70s succeeded in shifting the politics of race in the United States, making it easier to publicly challenge white hegemony than ever before in America’s history. However, public challenges to white dominance helped catalyze the formation of newly assorted white identity movements, such as the Alt-Right, to mobilize against so-called white genocide, against political correctness, policies of affirmative action, and the proliferation of multiculturalism in ‘post-racial’ America and in support of white nationalism. Presidential-candidate, Donald J. Trump ran his 2016 campaign on these same tenets of white victimhood, which attracted both educated and uneducated whites. His campaign helped move an otherwise questionable discourse of white victimhood into the acceptable mainstream. Why a narrative of white victimhood has resonated with so many educated whites needs investigating. This thesis capitalizes on the mixed-race interview encounter to display whiteness and investigate how college-educated white people frame their racial reality in the Trump era.

description: A distributed cooperative control law for persistent coverage tasks is proposed, capable of coordinating a team of heterogeneous agents in a structured environment. Team heterogeneity is considered both at vehicles' dynamics and at coverage capabilities levels. More specifically, the general dynamics of nonholonomic vehicles are considered. Agent heterogeneous sensing capabilities are addressed by means of the descriptor function framework, a set of analytical tools for controlling agents involved in generic coverage tasks. By means of formal arguments, we prove that the team performs the task and no collision occurs between agents nor with obstacles. A numerical simulation validates the proposed strategy.

description: I assess the potential of quantum computation. Broad and important applications must be found to justify construction of a quantum computer; I review some of the known quantum algorithms and consider the prospects for finding new ones. Quantum computers are notoriously susceptible to making errors; I discuss recently developed fault-tolerant procedures that enable a quantum computer with noisy gates to perform reliably. Quantum computing hardware is still in its infancy; I comment on the specifications that should be met by future hardware. Over the past few years, work on quantum computation has erected a new classification of computational complexity, has generated profound insights into the nature of decoherence, and has stimulated the formulation of new techniques in high-precision experimental physics. A broad interdisciplinary effort will be needed if quantum computers are to fulfill their destiny as the world's fastest computing devices. (This paper is an expanded version of remarks that were prepared for a panel discussion at the ITP Conference on Quantum Coherence and Decoherence, 17 December 1996.)

description: For a finite group $G$, let $d(G)$ denote the minimal number of elements required to generate $G$. In this paper, given a finite almost simple group $G$ and any maximal subgroup $H$ of $G$, we determine a precise upper bound for $d(H)$. In particular, we show that $d(H)\leq 5$, and that $d(H)\geq 4$ if and only if $H$ occurs in a known list. This improves a result of Burness, Liebeck and Shalev. The method involves the theory of crowns in finite groups.

description: A number of studies have reviewed the Nigerian Government and military strategy and quest to defeat the dreaded islamist militant known as Boko Haram vis-à-vis the claims of Boko Haram defeat and the seeming inability to contain the threats posed by members of the sect. Drawing references from scholarly articles, electronic channels, and other commissioned reports, the paper explains why despite the rise in security budget from about US$1.44 billion in 2009 to US2.81 billion in 2018, military-led counterinsurgency operation in Nigeria still faces some notable challenges. The paper further examines why Nigeria appears to be losing the war against Boko Haram, in contrast to its military expenditure and capabilities including its modest strides in Liberia and Sierra Leone. The study argues that Nigeria’s inability to contain the Boko Haram insurgency can be sited within the context of its homegrown systemic challenges; particularly, the politicisation of its national security. It therefore contends that a thorough overhaul of the military counterinsurgency operations at all levels is necessary for a more eﬀective and accountable force capable of defeating Boko Haram insurgency.
