description: The vector autoregressive moving average (VARMA) model is fundamental to the theory of multivariate time series; however, identifiability issues have led practitioners to abandon it in favor of the simpler but more restrictive vector autoregressive (VAR) model. We narrow this gap with a new optimization-based approach to VARMA identification built upon the principle of parsimony. Among all equivalent data-generating models, we use convex optimization to seek the parameterization that is simplest in a certain sense. A user-specified strongly convex penalty is used to measure model simplicity, and that same penalty is then used to define an estimator that can be efficiently computed. We establish consistency of our estimators in a double-asymptotic regime. Our nonasymptotic error bound analysis accommodates both model specification and parameter estimation steps, a feature that is crucial for studying large-scale VARMA algorithms. Our analysis also provides new results on penalized estimation of infinite-order VAR, and elastic net regression under a singular covariance structure of regressors, which may be of independent interest. We illustrate the advantage of our method over VAR alternatives on three real data examples.

description: Alzheimer’s disease is a neurodegenerative disorder characterized by the accumulation of amyloid-beta proteins in the brain, leading to loss of neuronal function and eventual death. Though the incidence of Alzheimer’s has risen in recent years, in no small part due to increasing lifespans, there has been little progress in the diagnosis and prevention of the disease. Diagnosis premortem is possible, but mainly through costly imaging or invasive brain biopsies, the latter of which is not recommended due to the possibility of further brain damage in the AD patient. Furthermore, AD treatments are difficult to study due to the difficulty of identifying patients as well as the diseases’ stubborn progression. Thus, there is an area of opportunity in accurately identifying these patients for both diagnostic and therapeutic purposes. There are many biomarkers correlated with the presence of AD, whether that be noticeable brain damage via scanning, the biomarkers of neuron cell death, or latent biomarkers which may cooccur in the progression of the disease. Given that these are non-linear relationships, computer-aided diagnosis may help in elucidating the diagnosis of AD. Random Forest models, given their ability to generate human-understandable trees and decision surfaces, are primed to assist medical professionals with the diagnosis of AD. This thesis analyzes several such models and evaluates their accuracies, as well as providing an overview of the state of the computer-aided medical diagnostics field.
Economic possibilities of long range commercial rocket transports
Creators: name: Beyer, David D
Publisher: name: California Institute of Technology
Year: 1953
Subjects: Aeronautics

description: In recent publications the economic aspects of both subsonic and supersonic jet transports have been discussed in some detail. Though the high subsonic speed turbojet transport, with some restrictions on range, was found to be of interest economically, no reasonable economic case was found for the supersonic jet transport utilizing either turbojet or ramjet engines. These calculations were made, however, with the assumption of a conventional level flight path. The purpose of this study is to investigate the possibility of using a rocket motor for propulsion of a supersonic transport flying a ballistic trajectory, with the hope that the direct operating expense can be reduced to a value comparable to that of subsonic transports, and thus to indicate the economic feasibility of such high speed transports.

It is shown that direct operating costs of rocket motored transports can be less than those indicated for the turbojet and ramjet transports, and in some cases, even approach the cost of operating currently proposed subsonic turbojet engine powered transports. Also the operating ranges can be extended beyond those possible with the supersonic jet transports postulated.

The flight technique used is one which allows the high thrust of the rocket motor to produce sufficient kinetic energy in the vehicle to permit it to coast and glide the desired range.

Performance is calculated with consideration given to endurance to acceleration limits imposed by human occupants. It is shown that payload optimization decreases design acceleration to a point that the human endurance is not the limiting factor. Weight breakdowns for the major components of the airplane are made, and costs computed are based on Air Transportation Association formulas given for the purpose of comparing operating costs of various proposed aircraft.

description: We propose a new search strategy for high-multiplicity hadronic final states. When new particles are produced at threshold, the distribution of their decay products is approximately isotropic. If there are many partons in the final state, it is likely that several will be clustered into the same large-radius jet. The resulting jet exhibits substructure, even though the parent states are not boosted. This "accidental" substructure is a powerful discriminant against background because it is more pronounced for high-multiplicity signals than for QCD multijets. We demonstrate how to take advantage of accidental substructure to reduce backgrounds without relying on the presence of missing energy. As an example, we present the expected limits for several R-parity violating gluino decay topologies. This approach allows for the determination of QCD backgrounds using data-driven methods, which is crucial for the feasibility of any search that targets signatures with many jets and suppressed missing energy.

Studies of the double-wedge and biconvex airfoils in hypersonic flow
Creators: name: Wunch, William Stuart
Publisher: name: California Institute of Technology
Year: 1948
Subjects: Aeronautics

description: Through the development of the high altitude rocket interest has turned to the investigation of aerodynamic problems beyond the supersonic regime. This domain of speed has been termed hypersonic, meaning high Mach number flight in a homogeneous medium whose molecules describe negligible mean free paths with respect to a chosen characteristic dimension. The thesis presented given an extension of two-dimensional supersonic airfoil theory to attack the problem of getting aerodynamic coefficients for the double-wedge and biconvex airfoils.

The shock wave equations along with those for Prandtl-Meyer flow have been modified by making approximations based on the hypersonic Mach numbers. These equations have been used to treat the following three cases:

(A) The Mach angle is much less than the deflection angle.

(B) The Mach angle is much greater than the deflection angle.

(C) The Mach angle is of the same order of magnitude as the deflection angle.

A brief discussion is made of the assumptions involved in the development of each of these flows to show that they do not violate basic principles. The hypersonic approximations already mentioned are then applied to these equations. In case (A) formulas are derived giving a quick approximation to the lift, drag, and moment coefficients. In case (B) formulas are found to be similar to those already obtained by the small perturbation method for supersonic flow. The results of case (C) show that a singular investigation must be made of each airfoil. The results of each of these cases are presented in the section titled "Applications to the Double-wedge and Biconvex Airfoils." Results for symmetrical double-wedge airfoils, whose maximum thicknesses are 10 per cent of the chord and are located at 25, 50, and 75 per cent of the chord, are plotted in the appendix.

description: The global dynamics of gene regulatory networks are known to show robustness to perturbations in the form of intrinsic and extrinsic noise, as well as mutations of individual genes. One molecular mechanism underlying this robustness has been identified as the action of so-called microRNAs that operate via feedforward loops. We present results of a computational study, using the modeling framework of stochastic Boolean networks, which explores the role that such network motifs play in stabilizing global dynamics. The paper introduces a new measure for the stability of stochastic networks. The results show that certain types of feedforward loops do indeed buffer the network against stochastic effects.

description: This paper introduces NN-STNE, a neural network using t-distributed stochastic neighbor embedding (t-SNE) as a hidden layer to reduce input dimensions by mapping long time-series data into shapelet membership probabilities. A Gaussian kernel-based mean square error preserves local data structure, while K-means initializes shapelet candidates due to the non-convex optimization challenge. Unlike existing methods, our approach uses t-SNE to address crowding in low-dimensional space and applies L1-norm regularization to optimize shapelet length. Evaluations on the UCR dataset and an electrical component manipulation task, like switching on, demonstrate improved clustering accuracy over state-of-the-art feature-learning methods in robotics.
An apparatus for the study of the turbulent diffusion flame

description: The project to study the turbulent diffusion flame, by the Department of Chemical Engineering of the California Institute of Technology, is quite comprehensive. Only a small portion of the project was included in the scope of this thesis.

A study will be made of the turbulent diffusion flame that is formed when fuel gas is introduced, through the end of a 1-inch-diameter tube, into air, flowing in a 4-inch-diameter tube, and combustion is started. The plan of investigation is divided into two parts. First, a study will be made of the mixing zone when combustion is not occurring; and secondly, a study will be made of the combustion zone when combustion is taking place.

The work accomplished in the scope of this thesis was the design and assistance in the fabrication and assembly of the equipment necessary to conduct this investigation. This was completed with the exception of the sampler to be used in obtaining samples of the burning gases. In addition, one series of tests was made at one stream velocity.

The equipment functioned very well during the series of runs. Recommendations for a few minor changes are included in this report. The incorporation of these changes should increase slightly both the speed of taking data and the accuracy of the results.

The results obtained in the series of tests indicated that the desired data can be obtained with this equipment.

description: We study for the first time a three-dimensional octahedron constellation for a space-based gravitational wave detector, which we call the Octahedral Gravitational Observatory (OGO). With six spacecraft the constellation is able to remove laser frequency noise and acceleration disturbances from the gravitational wave signal without needing LISA-like drag-free control, thereby simplifying the payloads and placing less stringent demands on the thrusters. We generalize LISA's time-delay interferometry to displacement-noise free interferometry (DFI) by deriving a set of generators for those combinations of the data streams that cancel laser and acceleration noise. However, the three-dimensional configuration makes orbit selection complicated. So far, only a halo orbit near the Lagrangian point L1 has been found to be stable enough, and this allows only short arms up to 1400 km. We derive the sensitivity curve of OGO with this arm length, resulting in a peak sensitivity of about $2\times10^{-23}\,\mathrm{Hz}^{-1/2}$ near 100 Hz. We compare this version of OGO to the present generation of ground-based detectors and to some future detectors. We also investigate the scientific potentials of such a detector, which include observing gravitational waves from compact binary coalescences, the stochastic background and pulsars as well as the possibility to test alternative theories of gravity. We find a mediocre performance level for this short-arm-length detector, between those of initial and advanced ground-based detectors. Thus, actually building a space-based detector of this specific configuration does not seem very efficient. However, when alternative orbits that allow for longer detector arms can be found, a detector with much improved science output could be constructed using the octahedron configuration and DFI solutions demonstrated in this paper.

description: We study the pair production of scalar top-quark partners decaying to a top-quark pair plus large missing energy at the LHC, a signature which appears in numerous models that address outstanding problems at the TeV-scale. The severe experimental search cuts require a description which combines higher-order corrections to both production and decay dynamics for a realistic final state. We do this at next-to-leading order in QCD for the first time. We find large, kinematic-dependent QCD corrections that differ dramatically depending upon the observable under consideration, potentially impacting the search for and interpretation of these states.

description: The high-energy Universe is potentially a great laboratory for searching new light bosons such as axion-like particles (ALPs). Cosmic sources are indeed the scene of violent phenomena that involve strong magnetic field and/or very long baselines, where the effects of the mixing of photons with ALPs could lead to observable effects. Two examples are archetypal of this fact, that are the Universe opacity to gamma-rays and the imprints of astrophysical magnetic turbulence in the energy spectra of high-energy sources. In the first case, hints for the existence of ALPs can be proposed whereas the second one is used to put constraints on the ALP mass and coupling to photons.

description: The Newhall-Potrero Oil Field is a long, narrow, asymmetrical anti line whose longitudinal axis trends northwest-southeast.  From a critical examination of many of the electric logs of the field, it is apparent that lensing of sands thickening and thinning of both sands and shales, and rapid facies changes are prevalent throughout the field.  Several of the oil sands in the Miocene either lens out or die out due to facies changes toward the southeast.  Two faults of major displacement are well shown in the logs of four wells, with other faulting probably occurring.
A stratigraphic correlation chart is presented to illustrate the rapid lithologic changes which prevail in the field.

	The Newhall-Potrero anticline is exposed on the surface in the hills north of the Potrero, but seams to die out to the southeast.	The rocks encountered at depth in the wells of the
Newhall-Potrero field outcrop to the south, but no ecru ate correlations between the surface exposures and the well logs were possible.
Studies of W boson plus jets production in p\bar{p} collisions at sqrt(s)=1.96 TeV

description: We present a comprehensive analysis of inclusive W(\to eν)+n-jet (n\geq 1,2,3,4) production in proton-antiproton collisions at a center-of-mass energy of 1.96 TeV at the Tevatron collider using a 3.7 fb^{-1} dataset collected by the D0 detector. Differential cross sections are presented as a function of the jet rapidities (y), lepton transverse momentum (p_T) and pseudorapidity (η), the scalar sum of the transverse energies of the W boson and all jets (H_T), leading dijet p_T and invariant mass, dijet rapidity separations for a variety of jet pairings for p_T-ordered and angular-ordered jets, dijet opening angle, dijet azimuthal angular separations for p_T-ordered and angular-ordered jets, and W boson transverse momentum. The mean number of jets in an event containing a W boson is measured as a function of H_T, and as a function of the rapidity separations between the two highest-p_T jets and between the most widely separated jets in rapidity. Finally, the probability for third-jet emission in events containing a W boson and at least two jets is studied by measuring the fraction of events in the inclusive W+2-jet sample that contain a third jet over a p_T threshold. The analysis employs a regularized singular value decomposition technique to accurately correct for detector effects and for the presence of backgrounds. The corrected data are compared to particle level next-to-leading order perturbative QCD predictions, predictions from all-order resummation approaches, and a variety of leading-order and matrix-element plus parton-shower event generators. Regions of the phase space where there is agreement or disagreement with the data are discussed for the different models tested.

title: EFFECT OF BEDDING TYPE AND SOIL INCORPORATION ON NITROGEN MINERALIZATION RATE OF BROILER LITTER AMENDED SOILS
Creators: name: Fitzgerald, Lydia
Publisher: name: University of Kentucky Libraries
Year: 2019

description: Broiler litter (BL) is a high value manure available to Kentucky crop producers to utilize as a fertilizer. The rate of BL application, timing of application, and method of application are all important factors to take into account when utilizing BL. A laboratory incubation was conducted to observe nitrogen (N) mineralization rates of BL amended soils over time under different conditions. Different application methods, application rates, watering frequencies, and bedding materials were used to determine their influence on N mineralization. Broiler litter applied on the soil surface, at lower rates, at lower watering frequency resulted in lower mineralization rates than BL that was incorporated, at higher rates and higher watering frequency. The rice hull bedding BL treatments had a significantly higher initial amount of NH4+-N than the wood-based bedding materials. The increased NH4+-N content produced a lower pH due to higher rates of nitrification. The difference in NH4+-N resulted in the rice hull BL treatments containing more inorganic N throughout the incubation. The wood-based BL contained significantly more carbon (C), zinc (Zn), and potassium (K). The results collected will help improve current nutrient recommendations and provide information that will help utilize BL more efficiently and economically.

description: We show that static and oscillating photon bubbles can be excited by diffused light in the laser cooled matter confined in a magneto-optical trap (MOT). The bubble instability is due to the coupling between the radiation field and the mean field oscillations of the ultra-cold gas, and it can provide a source for low frequency turbulence. We consider a diffusion dominated regime, which can be described by a radiation transport equation, coupled with the mean field equations for the cold atom gas. A perturbative analysis shows the occurrence of two different regimes with either oscillating or purely growing bubbles. This work could also be useful to understand similar processes in astrophysics.

In this work, we investigate how quantum fluctuations affect phase-locking in one or many van der Pol oscillators. We find that phase-locking is much more robust in the quantum model than in the equivalent classical model. Trapped-ion experiments are ideally suited to simulate van der Pol oscillators in the quantum regime via sideband heating and cooling of motional modes. We provide realistic experimental parameters for ${}^{171}\text{Yb}^+$ achievable with current technology.

description: Constant entropy rate (conditional entropies must remain constant as the sequence length increases) and uniform information density (conditional probabilities must remain constant as the sequence length increases) are two information theoretic principles that are argued to underlie a wide range of linguistic phenomena. Here we revise the predictions of these principles to the light of Hilberg's law on the scaling of conditional entropy in language and related laws. We show that constant entropy rate (CER) and two interpretations for uniform information density (UID), full UID and strong UID, are inconsistent with these laws. Strong UID implies CER but the reverse is not true. Full UID, a particular case of UID, leads to costly uncorrelated sequences that are totally unrealistic. We conclude that CER and its particular cases are incomplete hypotheses about the scaling of conditional entropies.

description: Family Ursidae Fischer, 1817. Mém. Soc. Imp. Nat. Moscow, 5:372. COMMENTS: Ailurus and Ailuropoda have been placed in a separate family by some; however, morphological and molecular evidence strongly supports the placement of Ailuropoda in this family (Chorn and Hoffmann, 1978; Davis, 1964; Goldman et al., 1989; Hendy, 1980«; O'Brien et al., 1985; Wozencraft, 1989«). Thenius (1979) placed Ailuropoda in the monotypic family Ailuropodidae, and Ailurus in the Procyonidae. The placement of Ailurus is certainly more controversial, with most phenetic studies placing it in the procyonids and most phylogenetic studies placing it near or in the ursids. See comments under Ailurus concerning its placement here. Morphological studies have supported the monophyly of three subfamilies (Hendy, 1980«; Kurtén, 1966; Thenius, 1979), although this has not been collaborated by a recent molecular approach (Goldman et al., 1989).

description: We report measurements of the correlation between intensities of noise at different frequencies on a tunnel junction under ac excitation, which corresponds to two-mode intensity correlations in optics. We observe positive correlation, \emph{i.e.} photon bunching, which exist only for certain relations between the excitation frequency and the two detection frequencies, depending on the dc bias of the sample. We demonstrate that these correlations are proportional to the fourth cumulant of current fluctuations.

description: Using first-principles molecular dynamics, we study the influence of nuclear quantum effects (NQEs) and nonlocal exchange--correlation density functionals (DFs) near molecular dissociation in liquid hydrogen. NQEs strongly influence intramolecular properties, such as bond stability, and are thus an essential part of the dissociation process. Moreover, by including DFs that account for either the self-interaction error or dispersion interactions, we find a much better description of molecular dissociation and metallization than previous studies based on classical protons and/or local or semi-local DFs. We obtain excellent agreement with experimentally measured optical properties along pre-compressed Hugoniots, and while we still find a first-order liquid--liquid transition at low temperatures, transition pressures are increased by more than 100 GPa.

description: We study the conformal symmetry described by $SL(2,R)_L \times SL(2,R)_R$ in the nonextremal Kerr black hole case. We calculate the central charges $c_{L,R}$ separately on a stretched horizon by the Hamiltonian gravity. In order to get two sets of conformal symmetry, we consider two Killing vectors each of which depends on either one of the two independent coordinates separated in the spirit of point-splitting from the angular coordinate of the corotating frame at the horizon. Then, we obtain the Bekenstein-Hawking entropy by the Cardy formula.

description: It is shown that the Pais-Uhlenbeck oscillator with damping, considered by Nesterenko, is a special case of a more general oscillator that has not only a first order, but also a third order friction term. If the corresponding damping constants, α and β, are both positive and below certain critical values, then the system is stable. In particular, if α= - β, then we have the unstable Nesterenko's oscillator

description: An in vitro system for studying the ionophore properties of the nicotinic acetylcholine receptor from the electric organs of Torpedo californica was developed. Efflux of ^(22)Na^+ from microsacs rich in AcChR was studied as a function of the addition of various agonists and antagonists to the medium. In the presence of agonists increased rates of efflux of ^(22)Na^+ occurred, and this affect was abolished in the presence of antagonists. The in vitro  response to varying concentrations of carbamylcholine was determined. The desensitization phenomenon occurring in vivo was also found to occur in vitro.

description: One of the many interesting features of quantum nonlocality is that the states of a multipartite quantum system cannot always be distinguished as well by local measurements as they can when all quantum measurements are allowed. In this work, we characterize the distinguishability of sets of multipartite quantum states when restricted to separable measurements -- those which contain the class of local measurements but nevertheless are free of entanglement between the component systems. We consider two quantities: The separable fidelity -- a truly quantum quantity -- which measures how well we can "clone" the input state, and the classical probability of success, which simply gives the optimal probability of identifying the state correctly. We obtain lower and upper bounds on the separable fidelity and give several examples in the bipartite and multipartite settings where these bounds are optimal. Moreover the optimal values in these cases can be attained by local measurements. We further show that for distinguishing orthogonal states under separable measurements, a strategy that maximizes the probability of success is also optimal for separable fidelity. We point out that the equality of fidelity and success probability does not depend on an using optimal strategy, only on the orthogonality of the states. To illustrate this, we present an example where two sets (one consisting of orthogonal states, and the other non-orthogonal states) are shown to have the same separable fidelity even though the success probabilities are different.

description: Free zinc is a critical regulator in signal transduction and affects many cellular processes relevant to cancer, including proliferation and cell death. Acting as a second messenger, altered free intracellular zinc has fundamental effects on regulating enzymes such as phosphatases and caspases. Therefore, the determination of free intracellular zinc levels is essential to assess its influence on the signaling processes involved in cancer development and progression. In this study, we compare three low-molecular-weight fluorescent probes, ZinPyr-1, TSQ, and FluoZin-3, for measuring free zinc in different mammary cell lines (MCF10A, MCF7, T47D, and MDA-MB-231). In summary, ZinPyr-1 is the most suitable probe for free Zn quantification. It responds well to calibration based on minimal fluorescence in the presence of the chelator TPEN (N,N,N′,N′-Tetrakis(2-pyridylmethyl)ethylenediamine) and maximal fluorescence by saturation with ZnSO4, resulting in the detection of free intracellular zinc in breast cancer subtypes ranging from 0.62 nM to 1.25 nM. It also allows for measuring the zinc fluxes resulting from incubation with extracellular zinc, showing differences in the zinc uptake between the non-malignant MCF10A cell line and the other cell lines. Finally, ZinPyr-1 enables the monitoring of sub-cellular distributions by fluorescence microscopy. Altogether, these properties provide a basis for the further exploration of free zinc in order to realize its full potential as a possible biomarker or even therapeutic target in breast cancer.
Towards a Predictive First-Principles Description of Solid Molecular Hydrogen with Density-Functional Theory

description: We examine the influence of the main approximations employed in density-functional theory descriptions of the solid phase of molecular hydrogen near dissociation. We consider the importance of nuclear quantum effects on equilibrium properties and find that they strongly influence intramolecular properties, such as bond fluctuations and stability. We demonstrate that the combination of both thermal and quantum effects make a drastic change to the predicted optical properties of the molecular solid, suggesting a limited value to dynamical, e.g., finite-temperature, predictions based on classical ions and static crystals. We also consider the influence of the chosen exchange--correlation density functional on the predicted properties of hydrogen, in particular, the pressure dependence of the band gap and the zero-point energy. Finally, we use our simulations to make an assessment of the accuracy of typically employed approximations to the calculation of the Gibbs free energy of the solid, namely the quasi-harmonic approximation for solids. We find that, while the approximation is capable of producing free energies with an accuracy of ~10 meV, this is not enough to make reliable predictions of the phase diagram of hydrogen from first-principles due to the small free energy differences seen between several potential structures for the solid; direct free energy calculations for quantum protons are required in order to make definite predictions.

description: The Glasgow Cooperative and Ray-Carroll Grain Growers, two successful farm supply-marketing cooperatives in Missouri, have made significant contributions to their 6,700 members and to their communities. Organized in 1923 and 1931, respectively, these cooperatives have developed grain marketing and storage facilities, dependable sources of farm supplies, a wide variety of related service for farmers, and a competitive influence on other agribusiness firms in the trade area. The study also points out the cooperatives' contributions to the welfare of local business communities, including participation in local activities and leadership.
Massive S-matrix of AdS_3 x S^3 x T^4 superstring theory with mixed 3-form flux

description: The type IIB supergravity AdS_3 x S^3 x T^4 background with mixed RR and NSNS 3-form fluxes is a near-horizon limit of a non-threshold bound state of D5-D1 and NS5-NS1 branes. The corresponding superstring world-sheet theory is expected to be integrable, opening the possibility of computing its exact spectrum for any values of the coefficient q of the NSNS flux and the string tension. In arXiv:1303.1447 we have found the tree-level S-matrix for the massive BMN excitations in this theory, which turned out to have a simple dependence on q. Here, by analyzing the constraints of symmetry and integrability, we propose an exact massive-sector dispersion relation and the exact S-matrix for this world-sheet theory. The S-matrix generalizes its recent construction in the q=0 case in arXiv:1303.5995.
