description: We prove that the squared singular values of a fixed matrix multiplied with a truncation of a Haar distributed unitary matrix are distributed by a polynomial ensemble. This result is applied to a multiplication of a truncated unitary matrix with a random matrix. We show that the structure of polynomial ensembles and of certain Pfaffian ensembles is preserved. Furthermore we derive the joint singular value density of a product of truncated unitary matrices and its corresponding correlation kernel which can be written as a double contour integral. This leads to hard edge scaling limits that also include new finite rank perturbations of the Meijer G-kernels found for products of complex Ginibre random matrices.

description: Through a comparative study of unpublished notes, lectures and seven panels from Aby Warburg's Mnemosyne Atlas, the author has attempted a reconstruction of the sense of Warburg’s latest studies on the migration of the Pathosformeln from Southern to Northern Europe, and on their weakening and reactivation processes in the context of seventeenth century Holland. One of the main leading elements in Warburg’s study is that of theatre conceived both as printed text, i.e. as physical vector capable of migrating pathos formulas, and as the site of the Shakespearian revolution that had introduced the concept of suspension, i.e. the void between impulse and action. Rembrandt, a careful observer of his own time, managed to reactivate Ovid’s mythological tales and Tacitus’s chronicles. He did so by including into his paintings elements that, like Shakespeare’s theatre, had revolutionised the art of his own time, thus breaking the long chain of minor fifteenth century Italian works portraying the same subjects definable as mere copies of the same models devoid of any originality. Although these works are considered as models of the seventeenth century Dutch “art officiel”. Rembrandt’s Conspiracy of Claudius Civilis marks a revolutionary break from those models. This work distinguishes itself from other contemporary thanks to Rembrandt’s formal and theological grafting of Leonardo’s Last Supper, as well as to his appliance of the Shakespearean “dramaturgy of suspension”, and to the painter’s study of Tacitus. This painting is defined by Warburg as “the astonishing event of an organically successful transformation of the heritage of Antiquity”.

Quantum Algorithm for Higher-Order Unconstrained Binary Optimization and MIMO Maximum Likelihood Detection

description: In this paper, we propose a quantum algorithm that supports a real-valued higher-order unconstrained binary optimization (HUBO) problem. This algorithm is based on the Grover adaptive search that originally supported HUBO with integer coefficients. Next, as an application example, we formulate multiple-input multiple-output maximum likelihood detection as a HUBO problem with real-valued coefficients, where we use the Gray-coded bit-to-symbol mapping specified in the 5G standard. The proposed approach allows us to construct an efficient quantum circuit for the detection problem and to analyze specific numbers of required qubits and quantum gates, whereas other conventional studies have assumed that such a circuit is feasible as a quantum oracle. To further accelerate the quantum algorithm, we also derive a probability distribution of the objective function value and determine a unique threshold to sample better states. Assuming a future fault-tolerant quantum computing, our proposed algorithm has the potential for significantly reducing query complexity in the classical domain and providing a quadratic speedup in the quantum domain.

description: A class of anyonic models for universal quantum computation based on weakly-integral anyons has been recently proposed. While universal set of gates cannot be obtained in this context by anyon braiding alone, designing a certain type of sector charge measurement provides universality. In this paper we develop a compilation algorithm to approximate arbitrary $n$-qutrit unitaries with asymptotically efficient circuits over the metaplectic anyon model. One flavor of our algorithm produces efficient circuits with upper complexity bound asymptotically in $O(3^{2\,n} \, \log{1/\varepsilon})$ and entanglement cost that is exponential in $n$. Another flavor of the algorithm produces efficient circuits with upper complexity bound in $O(n\,3^{2\,n} \, \log{1/\varepsilon})$ and no additional entanglement cost.

description: Many Department of Defense (DoD) development programs, such as aircraft development programs, are typically complex and long-lived. Often, these programs are structured to demonstrate significant capability in the form of prototypes, which may be additionally intended to provide lingering operational capability. As such, technology development activities frequently include design reviews known as the Initial Design Review (IDR) and the Final Design Review (FDR) that are not present in most other systems acquisitions.

IDR and FDR content is not explicitly defined in regulations or policies; rather, it is defined by the program office. However, since IDR and FDR are the Technology Development phase's equivalent to Preliminary Design Review and Critical Design Review, this technical note proposes that they should have similar criteria, scaled for Technology Development work.

This technical note presents definitions of IDR and FDR, their context in the acquisition life cycle, a comparison of engineering emphasis during IDR and FDR, IDR and FDR pre- and post-conditions, and IDR and FDR criteria and how to apply it. The audiences for this technical note are managers and developers of medium to large DoD systems that employ technology that is not mature enough to transition directly to systems development.

description: Singular behavior of the Laplace operator in spherical coordinates is investigated. It is shown that in course of transition to the reduced radial wave function in the Schrodinger equation there appears additional term consisting the Dirac delta function, which was unnoted during the full history of physics and mathematics. The possibility of avoiding this contribution from the reduced radial equation is discussed. It is demonstrated that for this aim the necessary and sufficient condition is requirement the fast enough falling of the wave function at the origin. The result does not depend on character of potential:is it regular or singular. The various manifestations and consequences of this observation are considered as well. The cornerstone in our approach is the natural requirement that the solution of the radial equation at the same time must obey to the full equation.

description: The concept of a system of systems (SoS) has become very popular over the last decade, resulting in books, conferences, technical papers, and reports. However, there is no consensus as to exactly what the term means, and it has been given many different, though related, definitions. This technical note identifies and describes the characteristics that have been used in various definitions of the term system of systems. These SoS characteristics vary along corresponding scales and can form the basis of corresponding "meters" that serve as indicators of where a system lies along the associated scale. This technical note also discusses two other classes of system characteristics: quality characteristics and programmatic characteristics and how similar meters can be used to describe where systems lie along the scales associated with these two additional sets of system characteristics. Finally, this technical note discusses the various benefits of using these system of systems characteristics to profile systems.
Electronic structure of ruthenium-doped iron chalcogenides

description: The structural and electronic properties of hypothetical Ru$_x$Fe$_{1-x}$Se and Ru$_x$Fe$_{1-x}$Te systems have been investigated from first principles within the density functional theory (DFT). Reasonable values of lattice parameters and chalcogen atomic positions in the tetragonal unit cell of iron chalcogenides have been obtained with the use of norm-conserving pseudopotentials. The well known discrepancies between experimental data and DFT-calculated results for structural parameters of iron chalcogenides are related to the semicore atomic states which were frozen in the used here approach. Such an approach yields valid results of the electronic structures of the investigated compounds. The Ru-based chalcogenides exhibit the same topology of the Fermi surface (FS) as that of FeSe, differing only in subtle FS nesting features. Our calculations predict that the ground states of RuSe and RuTe are nonmagnetic, whereas those of the solid solutions Ru$_x$Fe$_{1-x}$Se and Ru$_x$Fe$_{1-x}$Te become the single- and double-stripe antiferromagnetic, respectively. However, the calculated stabilization energy values are comparable for each system. The phase transitions between these magnetic arrangements may be induced by slight changes of the chalcogen atom positions and the lattice parameters $a$ in the unit cell of iron selenides and tellurides. Since the superconductivity in iron chalcogenides is believed to be mediated by the spin fluctuations in single-stripe magnetic phase, the Ru$_x$Fe$_{1-x}$Se and Ru$_x$Fe$_{1-x}$Te systems are good candidates for new superconducting iron-based materials.

description: Memristors are expected to form a major cornerstone in the upcoming renaissance of analog computing, owing to their very small spatial footprint and low power consumption. Due to the nature of their structure and operation, the response of a memristor is intrinsically tied to local variabilities in the device. This characteristic is amplified by currently employed semiconductor fabrication processes, which introduce spatial inhomogeneities into the structural fabric that makes up the layers of memristors. In this work, we propose a novel q-deformed current-voltage model for memristors based on the superstatistics framework, which allows the description of system-level responses while taking local variabilities into account. Applied on a Ag-Cu based synaptic memory cell, we demonstrate that our model has a 4-14% lower error than currently used models. Additionally, we show how the resulting q-parameter can be used to make statements about the internal makeup of the memristor, giving insights to spatial inhomogeneities and quality control.

description: Recordings in the human medial temporal lobe have found many neurons that respond to pictures (and related stimuli) of just one particular person out of those presented. It has been proposed that these are concept cells, responding to just a single concept. However, a direct experimental test of the concept cell idea appears impossible, because it would need the measurement of the response of each cell to enormous numbers of other stimuli. Here we propose a new statistical method for analysis of the data, that gives a more powerful way to analyze how close data are to the concept-cell idea. It exploits the large number of sampled neurons, to give sensitivity to situations where the average response sparsity is to much less than one response for the number of presented stimuli. We show that a conventional model where a single sparsity is postulated for all neurons gives an extremely poor fit to the data. In contrast a model with two dramatically different populations give an excellent fit to data from the hippocampus and entorhinal cortex. In the hippocampus, one population has 7% of the cells with a 2.6% sparsity. But a much larger fraction 93% respond to only 0.1% of the stimuli. This results in an extreme bias in the reported responsive of neurons compared with a typical neuron. Finally, we show how to allow for the fact that some of reported identified units correspond to multiple neurons, and find that our conclusions at the neural level are quantitatively changed but strengthened, with an even stronger difference between the two populations.

description: The 2010 Affordable Care Act expanded Medicaid eligibility to states’ residents with incomes below the federal poverty line, creating both opportunities and challenges to hospitals in states that adopted the new Medicaid eligibility. This article explores the effect of Medicaid expansions on nonprofit hospitals. Using data from Internal Revenue Service and a difference-in-differences design, this article examines the impact of the expansions on the number of, contributions to, and profitability of nonprofit hospitals. The results suggest that Medicaid expansions did not affect the number and profitability of nonprofit hospitals; however, the expansions were associated with a reduction in contributions to certain types of hospitals by around 23%. Therefore, the effects of policy changes vary by the type of nonprofit hospitals, which then need to find better strategies to cope with these changes.

description: We present the results of an ensemble of SPH simulations that follow the evolution of prestellar cores for $0.2\,{\rm Myr}$. All the cores have the same mass, and start with the same radius, density profile, thermal and turbulent energy. Our purpose is to explore the consequences of varying the fraction of turbulent energy, $δ_\mathrm{sol}$, that is solenoidal, as opposed to compressive; specifically we consider $δ_\mathrm{sol}=1,\,2/3,\,1/3,\,1/9\;{\rm and}\;0$. For each value of $δ_\mathrm{sol}$, we follow ten different realisations of the turbulent velocity field, in order also to have a measure of the stochastic variance blurring any systematic trends. With low $δ_\mathrm{sol}(\!1/3)$ disc fragmentation dominates and delivers relatively low mass stars. There are no discernible systematic trends in the multiplicity statistics obtained with different $δ_\mathrm{sol}$.

description: The phase space analysis of cosmological parameters $Ω_ϕ$ and $γ_ϕ$ is given. Based on this, the well-known quintessence cosmology is studied with an exponential potential $V(ϕ)=V_{0}\exp(-λϕ)$. Given observational data, the current state of universe could be pinpointed in the phase diagrams, thus making the diagrams more informative. The scaling solution of quintessence usually is not supposed to give the cosmic accelerating expansion, but we prove it could educe the transient acceleration. We also find that the differential equations of system used widely in study of scalar field are incomplete, and then a numerical method is used to figure out the range of application.

We then show that any expression which involves matrix elements can be reformulated by the expectation values of these non-Hermitian operators and vice versa. We consider the condition of pure states and pure product states and rewrite them in terms of expectation values and density matrix elements respectively. We utilize expectation values of these operators to present the condition for separability of ${C}^d \otimes {C}^d$ bipartite states. With the help of our separability criterion we detect entanglement in certain classes of higher dimensional bipartite states.

description: Architectural tactics are fundamental design decisions. They are the building blocks for both architectural design and analysis. A catalog of architectural tactics has now been in use for several years in academia and industry. This report illustrates the use of this catalog in industrial applications, describing how tactics can be used in both design and analysis. The report further shows how the needs of practice have caused the catalog of availability tactics to be updated, but demonstrates that the underlying structure of the tactics categorization has remained stable. Finally, a real-world example is provided of the application of the updated set of availability tactics, showing how it illuminates design decisions, as guided by associated heuristics and analytic models.

description: In light of the recent detection of direct evidence for the formation of Kelvin-Helmholtz instabilities in the Orion nebula, we expand upon previous modelling efforts by numerically simulating the shear-flow driven gas and dust dynamics in locations where the H$_{II}$ region and the molecular cloud interact. We aim to directly confront the simulation results with the infrared observations. Methods: To numerically model the onset and full nonlinear development of the Kelvin-Helmholtz instability we take the setup proposed to interpret the observations, and adjust it to a full 3D hydrodynamical simulation that includes the dynamics of gas as well as dust. A dust grain distribution with sizes between 5-250 nm is used, exploiting the gas+dust module of the MPI-AMRVAC code, in which the dust species are represented by several pressureless dust fluids. The evolution of the model is followed well into the nonlinear phase. The output of these simulations is then used as input for the SKIRT dust radiative transfer code to obtain infrared images at several stages of the evolution, which can be compared to the observations. Results: We confirm that a 3D Kelvin-Helmholtz instability is able to develop in the proposed setup, and that the formation of the instability is not inhibited by the addition of dust. Kelvin-Helmholtz billows form at the end of the linear phase, and synthetic observations of the billows show striking similarities to the infrared observations. It is pointed out that the high density dust regions preferentially collect on the flanks of the billows. To get agreement with the observed Kelvin-Helmholtz ripples, the assumed geometry between the background radiation, the billows and the observer is seen to be of critical importance.

description: By comparing the photo-induced magnetization dynamics in simple layered systems we show how light-induced modifications of the magnetic anisotropy directly enhance the magnetization. It is observed that the spin precession in (CH3NH3)2CuCl4, initiated by a light pulse, increases in amplitude at the critical temperature TC. The phenomenon is related to the dependence of the critical temperature on the axial magnetic anisotropy. The present results underline the possibility and the importance of the optical modifications of the anisotropy, opening new paths toward the control of the magnetization state for ultrafast memories.

description: We explore an unresolved controversy in the literature about the accuracy of Smoothed Particle Hydrodynamics (SPH) in modeling the accretion of gas onto a binary system, a problem with important applications to the evolution of proto-binaries as well as accreting binary super massive black holes. It has previously been suggested that SPH fails to model the flow of loosely bound material from the secondary to primary Roche lobe and that its general prediction that accretion drives mass ratios upwards is numerically flawed. Here we show with 2D SPH that this flow from secondary to primary Roche lobe is a sensitive function of gas temperature and that this largely explains the conflicting claims in the literature which have hitherto been based on either 'cold' SPH simulations or 'hot' grid based calculations. We present simulations of a specimen 'cold' and 'hot' accretion scenario which are numerically converged and evolved into a steady state. Our analysis of the conservation of the Jacobi integral of accreting particles indicates that our results are not strongly compromised by numerical dissipation. We also explore the low resolution limit and find that simulations where the ratio of SPH smoothing length to disc scale height at the edge of the circumsecondary is less than 1 accurately capture binary accretion rates.

description: Young pulsars deviate from a perfectly regular spin-down by two non-deterministic phenomena: impulsive glitches and timing noise. Both phenomena are interesting per se, and may provide insights into the superfluid properties of neutron stars, but they also act as a barrier to high-precision pulsar timing and gravitational wave experiments. We study a minimal stochastic model to describe the spin-down of a multicomponent neutron star, with fluctuations in both the internal and external torques. The power spectral density and timing noise strength of this kind of model can be obtained analytically, and compared with known results from pulsar timing observational campaigns. In particular, the presence of flat regions of the power spectral density can be interpreted as a signature of the presence of internal superfluid components. We also derive the expected scaling of the timing noise strength with the pulsar's rotational parameters (or characteristic age). Therefore, the present framework offers a theoretical guideline to interpret the observed features of timing noise in both single pulsars and across pulsar population.

description: For several years, the software engineering community has been working to identify practices aimed at developing more secure software. Although some foundational work has been performed, efforts to measure software security assurance have yet to materialize in any substantive fashion. As a result, decision makers (e.g., development program and project managers, acquisition program offices) lack confidence in the security characteristics of their software-reliant systems. The CERT® Program at Carnegie Mellon University's Software Engineering Institute (SEI) has chartered the Software Security Measurement and Analysis (SSMA) Project to advance the state-of-the-practice in software security measurement and analysis. The SSMA Project is exploring how to use risk analysis to direct an organization's software security measurement and analysis efforts. The overarching goal is to develop a risk-based approach for measuring and monitoring the security characteristics of interactively complex software-reliant systems across the life cycle and supply chain. To accomplish this goal, the project team has developed the SEI Integrated Measurement and Analysis Framework (IMAF) and refined the SEI Mission Risk Diagnostic (MRD). This report is an update to the technical note, Integrated Measurement and Analysis Framework for Software Security (CMU/SEI-2010-TN-025), published in September 2010. This report presents the foundational concepts of a risk-based approach for software security measurement and analysis and provides an overview of the IMAF and the MRD.

description: For performing successful measurements within limited experimental time, efficient use of preliminary data plays a crucial role. This work shows that a simple feedforward type neural networks approach for learning preliminary experimental data can provide quick access to simulate the experiment within the learned range. The approach is especially beneficial for physical properties measurements with scanning on multiple axes, where derivative or integration of data are required to obtain the objective quantity. Due to its simplicity, the learning process is fast enough for the users to perform learning and simulation on-the-fly by using a combination of open-source optimization techniques and deep-learning libraries. Here such a tool for augmenting the experimental data is proposed, aiming to help researchers to decide the most suitable experimental conditions before performing costly experiments in real. Furthermore, this tool can also be used from the perspective of taking advantage of reutilizing and repurposing previously published data, accelerating data-driven exploration of functional materials.

description: The effects of sound and mechanical vibrations on blood flow and in vitro and in vivo blood cells were previously reported in various studies. Frequency-based stimulation and sound vibrations were shown to have a positive effect on peripheral blood flow, blood aggregation, Red Blood Cells longevity and enhanced release of Nitric Oxide which supports improved blood oxygenation. Different frequencies were also reported to have discrete effects on cells and physiological mechanisms. In this preliminary study, we investigated the effect of 20 minutes exposure to audible sound stimuli comprising recordings of spatial sound projections of a singing bowl at 40 Hz and 73 Hz compared to 20 minutes silence in a Faraday cage (control) on in vitro Red Blood Cells and White Blood Cells. We find that the sound stimuli have a highly significant effect on the longevity of both Red and White Blood Cells with a differentiation in effect across frequencies and projections compared to control. Results could indicate a cost-effective treatment to support improved soundness of blood transfusions as well as non-invasive interventions to increase circulating blood cells.

description: Neurodegenerative diseases are frequently associated with structural changes in the brain. Magnetic Resonance Imaging (MRI) scans can show these variations and therefore be used as a supportive feature for a number of neurodegenerative diseases. The hippocampus has been known to be a biomarker for Alzheimer disease and other neurological and psychiatric diseases. However, it requires accurate, robust and reproducible delineation of hippocampal structures. Fully automatic methods are usually the voxel based approach, for each voxel a number of local features were calculated. In this paper we compared four different techniques for feature selection from a set of 315 features extracted for each voxel: (i) filter method based on the Kolmogorov-Smirnov test; two wrapper methods, respectively, (ii) Sequential Forward Selection and (iii) Sequential Backward Elimination; and (iv) embedded method based on the Random Forest Classifier on a set of 10 T1-weighted brain MRIs and tested on an independent set of 25 subjects. The resulting segmentations were compared with manual reference labelling. By using only 23 features for each voxel (sequential backward elimination) we obtained comparable state of-the-art performances with respect to the standard tool FreeSurfer.

title: Imaging changes in the rodent brain using diffusion weighted multiple boli arterial spin labelling
Creators: name: Paterson, Samantha

Subjects: subject: Brain, Blood brain barrier, MRI, Arterial spin labelling, ASL, DWASL, Diffusion weighted arterial spin labelling, human African trypanosomiasis, sleeping sickness.

description: This thesis combines the quantification of a new arterial spin labelling (ASL) sequence, and the development of a diffusion weighted ASL (DWASL) sequence, to examine blood brain barrier (BBB) impairment. The blood brain barrier maintains the delicate neuroenvironment in the brain by controlling influx and efflux of cells and molecules. Many neurological disorders are effected by an impairment of the BBB. Current magnetic resonance imaging (MRI) methods to image BBB dysfunction involve the use of a contrast agent, which is invasive and not sensitive to subtle changes in BBB permeability. Non-invasive MR methods such as ASL, are able to measure perfusion and produce cerebral blood flow (CBF) maps of the brain. ASL however has an inherently low signal and therefore development of high signal-tonoise ratio (SNR) sequences are needed. Multiple boli ASL (mbASL) is a high SNR sequence that would be suitable for producing CBF maps but lacks quantification. Human African trypanosomiasis (HAT), a parasitic disease native to Africa, results in a progressive diffuse impairment of the BBB throughout the disease course. A murine model of HAT was used to examine water exchange and cerebral blood flow changes with DWASL. Chapter 1 outlines the current literature on the blood brain barrier, HAT and splenomegaly. Chapter 2 introduces the theory of MRI, which is the imaging method used throughout the thesis. Chapter 3 provides a literature review of the ASL sequence and subsequent development of diffusion weighted ASL. The review outlines the main ASL sequences and introduces multiple boli ASL, followed by diffusion weighted ASL. These two sequences are used throughout this thesis. Chapter 4, the first results chapter, experimentally validates the quantification of the mbASL sequence. Chapter 5 outlines the development of diffusion weighted mbASL which could potentially image changes in water exchange across the BBB. Chapter 6 and Chapter 7 use the HAT mouse model first to examine changes in the water exchange in the brain and then to serially image changes in spleen volume.

description: The role of schedule is fundamental to the acquisition of a particular system. This topic is of even more importance to acquisition in a system-of-systems environment. This report examines the issue of schedule considerations for interoperable acquisition. First, a Gedanken red team project is used to explore concerns about schedule in interoperable acquisition. Then, those concerns are examined in light of current requirements regarding schedule. From that examination, several research questions are proposed.
