description: The intensive archaeological survey of over 18 square miles of the San Xavier Indian Reservation has produced a substantial body of new data regarding prehistoric utilization of this portion of the Tucson Basin. In this chapter a subset of the San Xavier Project data base is utilized to examine stability and change in the prehistoric settlement patterns within the study area. There are three major goals for the present study. The first goal is to describe the analysis methods employed. The second goal is to describe the data base, to characterize its variability, and to identify patterns in this variability. The third goal is to consider hypotheses and models that can help explain the patterns observed in the data. This is a draft report.

description: Mobile impurities in a Bose-Einstein condensate form quasiparticles called polarons. Here, we show that two such polarons can bind to form a bound bipolaron state. Its emergence is caused by an induced nonlocal interaction mediated by density oscillations in the condensate, and we derive using field theory an effective Schrödinger equation describing this for arbitrarily strong impurity-boson interaction. We furthermore compare with Quantum Monte Carlo simulations finding remarkable agreement, which underlines the predictive power of the developed theory. It is found that bipolaron formation typically requires strong impurity interactions beyond the validity of more commonly used weak-coupling approaches that lead to local Yukawa-type interactions. We predict that the bipolarons are observable in present experiments and describe a procedure to probe their properties.

description: We study the effects of negative spatial curvature on the statistics of inhomogeneities in open cosmological models. In particular we examine the suppression of large-separation correlations in density and gravitational potential fluctuations and the resulting suppression of large-angle correlations in the anisotropy of the microwave background radiation. We obtain an expression which gives the {\it minimum} amount of suppression of correlations for any statistical distribution described by a ``power spectrum''. This minimum suppression requires that the correlations fall off exponentially above the curvature scale. To the extent that the observed correlations in the temperature anisotropy extend to large angular scales, one can set a lower bound to the radius of curvature and hence on $Ω_0$.

Near - Connecting Couples Living Over Long Distances
Creators: name: Faryal  Khalid
Publisher: name: Carnegie Mellon University
Year: 2015
Subjects: Design

description: The pressures of job markets and globalization have forced an increasing number of couples to live apart. Technology mediates most of the communication for long distance couples but while it is efficient in transmission of information it has failed to allow couples to experience true closeness, in a natural, seamless manner. Through a yearlong research project, I propose ‘Near’ - a system that takes into account the unique needs of long distance couples to ensure that they experience closeness through expressivity, awareness and joint action. The focus of the project is to allow for an emphasis on emotion and shared sense of place.
Goal-Oriented Optimal Design of Experiments for Large-Scale Bayesian Linear Inverse Problems

description: We develop a framework for goal-oriented optimal design of experiments (GOODE) for large-scale Bayesian linear inverse problems governed by PDEs. This framework differs from classical Bayesian optimal design of experiments (ODE) in the following sense: we seek experimental designs that minimize the posterior uncertainty in the experiment end-goal, e.g., a quantity of interest (QoI), rather than the estimated parameter itself. This is suitable for scenarios in which the solution of an inverse problem is an intermediate step and the estimated parameter is then used to compute a QoI. In such problems, a GOODE approach has two benefits: the designs can avoid wastage of experimental resources by a targeted collection of data, and the resulting design criteria are computationally easier to evaluate due to the often low-dimensionality of the QoIs. We present two modified design criteria, A-GOODE and D-GOODE, which are natural analogues of classical Bayesian A- and D-optimal criteria. We analyze the connections to other ODE criteria, and provide interpretations for the GOODE criteria by using tools from information theory. Then, we develop an efficient gradient-based optimization framework for solving the GOODE optimization problems. Additionally, we present comprehensive numerical experiments testing the various aspects of the presented approach. The driving application is the optimal placement of sensors to identify the source of contaminants in a diffusion and transport problem. We enforce sparsity of the sensor placements using an $\ell_1$-norm penalty approach, and propose a practical strategy for specifying the associated penalty parameter.

A Formal Approach to Analyzing Cyber-Forensics Evidence

description: The frequency and harmfulness of cyber-attacks are increasing every day, and with them also the amount of data that the cyber-forensics analysts need to collect and analyze. In this paper, we propose a formal analysis process that allows an analyst to filter the enormous amount of evidence collected and either identify crucial information about the attack (e.g., when it occurred, its culprit, its target) or, at the very least, perform a pre-analysis to reduce the complexity of the problem in order to then draw conclusions more swiftly and efficiently. We introduce the Evidence Logic EL for representing simple and derived pieces of evidence from different sources. We propose a procedure, based on monotonic reasoning, that rewrites the pieces of evidence with the use of tableau rules, based on relations of trust between sources and the reasoning behind the derived evidence, and yields a consistent set of pieces of evidence. As proof of concept, we apply our analysis process to a concrete cyber-forensics case study.

description: The mean area of two-dimensional unpressurised vesicles, or self-avoiding loops of fixed length $N$, behaves for large $N$ as $A_0 N^{3/2}$, while their mean square radius of gyration behaves as $R^2_0 N^{3/2}$. The amplitude ratio $A_0/R_0^2$ is computed exactly and found to equal $4π/5$. The physics of the pressurised case, both in the inflated and collapsed phases, may be usefully related to that of a complex O(n) field theory coupled to a U(1) gauge field, in the limit $n \to 0$.

Cooling Gas Outflows from Galaxies
Creators: name: Wang, Boqi
Publisher: name: arXiv
Year: 1994
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We study steady, radial gas outflows from galaxies in an effort to understand the way tenuous and hot gas is transported to large distances away from galaxies. In particular, we obtain solutions for outflow problems, and study the outflow topology, effects of the galaxy mass, the size of outflow regions, the efficiency of radiative cooling, and the fate of the cooled gas. Under general power-law forms for the cooling function and the gravitational field of galaxies, we show that the outflow solutions are determined by the two-parameter initial conditions. In an analogy with stellar wind or accretion problems, we demonstrate that there exists no transonic flow, but either subsonic or supersonic flows are obtainable. Solutions of the supersonic outflows are studied in detail as they are most likely to carry gas to large distances away from galaxies. We find that if gravity is weak, the outflow is characterized by the ratio of the radiative cooling time to the flow time, $t_c/t_f$. The importance of the galactic gravitational field is characterized by the fractional energy lost radiatively within the flow time in outflows with velocity equal to the circular velocity of the galaxy; if the fraction is small, gravity stops the outflow before the gas has a chance to cool radiatively. In the case the gas does cool radiatively, the cooled gas is most likely to form clouds via various instabilities. The clouds coast farther away from the galaxy because of the finite kinetic energy they inherit. We find that the hot gas in dwarf galaxies can either flow out as galactic winds, or cools radiatively to form clouds. In the latter case, the clouds escape the galaxies. In contrast, massive galaxies like our own tend to confine the gas. We present the surface brightness in various x-ray energy bands. We also estimate the mean

description: In the third part of our photometric study of the star-forming region NGC 346/N~66 and its surrounding field in the Small Magellanic Cloud (SMC), we focus on the large number of low-mass pre-main sequence (PMS) stars revealed by the Hubble Space Telescope Observations with the Advanced Camera for Surveys. We investigate the origin of the observed broadening of the pre-main sequence population in the $V-I$, $V$ CMD. The most likely explanations are either the presence of differential reddening or an age spread among the young stars. Assuming the latter, simulations indicate that we cannot exclude the possibility that stars in NGC 346 might have formed in two distinct events occurring about 10 and 5 Myr ago, respectively. We find that the PMS stars are not homogeneously distributed across NGC 346, but instead are grouped in at least five different clusters. On spatial scales from 0.8$''$ to 8$''$ (0.24 to 2.4 pc at the distance of the SMC) the clustering of the PMS stars as computed by a two-point angular correlation function is self-similar with a power law slope $γ\approx -0.3$. The clustering properties are quite similar to Milky Way star forming regions like Orion OB or $ρ$ Oph. Thus molecular cloud fragmentation in the SMC seems to proceed on the same spatial scales as in the Milky Way. This is remarkable given the differences in metallicity and hence dust content between SMC and Milky Way star forming regions.

description: We investigate the development of spectator (light test) field condensates due to their quantum fluctuations in a de Sitter inflationary background, making use of the stochastic formalism to describe the system. In this context, a condensate refers to the typical field value found after coarse-graining using the Hubble scale $H$, which can be essential to seed the initial conditions required by various post-inflationary processes. We study models with multiple coupled spectators and for the first time we demonstrate that new forms of stationary solution exist (distinct from the standard exponential form) when the potential is asymmetric. Furthermore, we find a critical value for the inter-field coupling as a function of the number of fields above which the formation of stationary condensates collapses to $H$. Considering some simple two-field example potentials, we are also able to derive a lower limit on the coupling, below which the fluctuations are effectively decoupled, and the standard stationary variance formulae for each field separately can be trusted. These results are all numerically verified by a new publicly available python class (https://github.com/umbralcalc/nfield) to solve the coupled Langevin equations over a large number of fields, realisations and timescales. Further applications of this new tool are also discussed.

description: We show a Birthday Paradox for self-intersections of Markov chains with uniform stationary distribution. As an application, we analyze Pollard's Rho algorithm for finding the discrete logarithm in a cyclic group $G$ and find that if the partition in the algorithm is given by a random oracle, then with high probability a collision occurs in $Θ(\sqrt{|G|})$ steps. Moreover, for the parallelized distinguished points algorithm on $J$ processors we find that $Θ(\sqrt{|G|}/J)$ steps suffices. These are the first proofs of the correct order bounds which do not assume that every step of the algorithm produces an i.i.d. sample from $G$.

Resonance dipole-dipole interaction between two accelerated atoms in the presence of a reflecting plane boundary

description: We study the resonant dipole-dipole interaction energy between two uniformly accelerated identical atoms, one excited and the other in the ground state, prepared in a correlated {\em Bell-type} state, and interacting with the scalar field or the electromagnetic field nearby a perfectly reflecting plate. We suppose the two atoms moving with the same uniform acceleration, parallel to the plane boundary, and that their separation is constant during the motion. We separate the contributions of vacuum fluctuations and radiation reaction field to the resonance energy shift of the two-atom system, and show that Unruh thermal fluctuations do not affect the resonance interaction, which is exclusively related to the radiation reaction field. However, nonthermal effects of acceleration in the radiation-reaction contribution, beyond the Unruh acceleration-temperature equivalence, affect the resonance interaction energy. By considering specific geometric configurations of the two-atom system relative to the plate, we show that the presence of the mirror significantly modifies the resonance interaction energy between the two accelerated atoms. In particular, we find that new and different features appear with respect to the case of atoms in the free space, related to the presence of the boundary and to the peculiar structure of the quantum electromagnetic field vacuum in the locally inertial frame. Our results suggest the possibility to exploit the resonance interaction between accelerated atoms, as a probe for detecting the elusive effects of atomic acceleration on radiative processes.
description: Symmetry, Special Issue "New Trends in Quantum Electrodynamics"; 15 pages, 3 figures. This paper extends to uniformly accelerated atoms some results obtained in arXiv:1711.08249 for intertial atoms, using the same method to separate vacuum fluctuations and radiation reaction contributions

The Neel temperature of $β$-Li$_2$IrO$_3$ increases with the slope of 0.9 K/GPa upon initial compression, but the reduction in the polarization field $H_c$ reflects a growing instability of the incommensurate order. At 1.4 GPa, the ordered state breaks down upon a first-order transition giving way to a new ground state marked by the coexistence of dynamically correlated and frozen spins. This partial freezing in the absence of any conspicuous structural defects may indicate classical nature of the resulting pressure-induced spin liquid, an observation paralleled to the increase in the nearest-neighbor off-diagonal exchange $Γ$ under pressure.

description: Recently, a functional integral representation was proposed by Weller (Weller, W.: phys.~stat.~sol.~(b) {\bf 162}, 251 (1990)), in which the fermionic fields strictly satisfy the constraint of no double occupancy at each lattice site. This is achieved by introducing spin dependent Bose fields. The functional integral method is applied to the single impurity Anderson model both in the Kondo and mixed-valence regime. The f-electron Green's function and susceptibility are calculated using an Ising-like representation for the Bose fields. We discuss the difficulty to extract a spectral function from the knowledge of the imaginary time Green's function. The results are compared with NCA calculations.

Bien que les maladies transmises par les moustiques touchent l'ensemble de la société, ces enfants sont nés presque exclusivement de femmes pauvres et généralement non-blanches. La thèse principale de cet ouvrage est que  cette épidémie a mis en évidence des disparités sanitaires extrêmes et une injustice en matière de procréation, seules les femmes les plus riches ayant accès à des avortements sûrs.
Ces disparités reflètent l’existence de clivages socio-économiques et raciaux/ethniques au Brésil. Une épidémie est donc à la fois un événement biologique et politique.

description: The ultraviolet spectra of all ``weak emission line central stars of planetary nebulae'' (WELS) with available IUE data are presented and discussed. We performed line identifications, equivalent width and flux measurements for several features in their spectra. We found that the WELS can be divided in three different groups regarding their UV: i) Strong P-Cygni profiles (mainly in CIV 1549); ii) Weak P-Cygni features and iii) Absence of P-Cygni profiles. The last group encompasses stars with a featureless UV spectrum or with intense emission lines and a weak continuum, which are most likely of nebular origin. We have measured wind terminal velocities for all objects presenting P-Cygni profiles in N V 1238 and/or C IV 1549. The results obtained were compared to the UV data of the two prototype stars of the [WC]-PG 1159 class, namely, A30 and A78. For WELS presenting P-Cygnis, most of the terminal velocities fall in the range ~1000-1500 km/s, while [WC]-PG 1159 stars possess much higher values, of about 3000 km/s. The [WC]-PG1159 stars are characterized by intense, simultaneous P-Cygni emissions in the 1150-2000A interval of N V 1238, O V 1371 and C IV 1549. In contrast, we found that O V 1371 is very weak or absent in the WELS spectra. On the basis of the ultraviolet spectra alone, our findings indicate that [WC]-PG 1159 stars are distinct from the WELS, contrary to previous claims in the literature.

description: By employing the moduli space approximation, we analytically calculate the gravitational wave signatures emitted upon the merger of two extremally charged dilatonic black holes. We probe several values of the dilatonic coupling constant $a$, and find significant departures from the Einstein--Maxwell ($a=0$) counterpart studied in arXiv:1704.08520. For (low energy) string theory black holes $(a=1)$ there are no coalescence orbits and only a memory effect is observed, whereas for an intermediate value of the coupling $(a=1/\sqrt{3})$ the late-time merger signature becomes exponentially suppressed, compared to the polynomial decay in the $a=0$ case without a dilaton. Such an imprint is in principle observable and could reveal the presence of a scalar field (as for example predicted by string theory) in black hole mergers.

description: We have designed, fabricated and measured high-Q $λ/2$ coplanar waveguide microwave resonators whose resonance frequency is made tunable with magnetic field by inserting a DC-SQUID array (including 1 or 7 SQUIDs) inside. Their tunability range is 30% of the zero field frequency. Their quality factor reaches up to 3$\times10^4$. We present a model based on thermal fluctuations that accounts for the dependance of the quality factor with magnetic field.

description: We study the transition between sharp and smooth density distributions at the edges of Quantum Hall Liquids in the presence of interactions. We find that, for strong confining potentials, the edge of a $ν=1$ liquid is described by the $Z_F=1$ Fermi Liquid theory, even in the presence of interactions, a consequence of the chiral nature of the system. When the edge confining potential is decreased beyond a point, the edge undergoes a reconstruction and electrons start to deposit a distance $\sim 2$ magnetic lengths away from the initial QH Liquid. Within the Hartree-Fock approximation, a new pair of branches of gapless edge excitations is generated after the transition. We show that the transition is controlled by the balance between a long-ranged repulsive Hartree term and a short-ranged attractive exchange term. Such transition also occurs for Quantum Dots in the Quantum Hall Regime, and should be observable in resonant tunneling experiments. Electron tunneling into the reconstructed edge is also discussed.

description: Management of bone reconstruction in the presence of inflammation is a challenging and costly clinical problem. It can result in extended repair times, poor bone healing, delayed unions, non-unions, revision surgery, and in the extreme, amputation or death. Acute inflammation can impair clinical reconstruction outcomes by compromising the early stages of bone repair and regeneration, while chronic inflammation exacerbates these effects leading to further significant loss of bone and associated function. Inflammation usually involves cells of the innate immune response, including neutrophils, macrophages and dendritic cells. Using J774a.1 (a mouse macrophage cell line) and fetal skin dendritic cells, I determined that lipopolysaccharide (LPS) induced a pro-inflammatory phenotype, which creates a microenvironment that inhibits bone morphogenetic protein 2 (BMP-2) induced stem cell osteoblastogenesis. However, the addition of an anti-inflammatory/immunoregulatory cytokine Interleukin 10 (IL-10), in the presence of LPS, directs this classical inflammatory response toward an alternative activated microenvironment that is permissive for BMP-2 osteoblastic differentiation. As BMP-2 can direct both osteoclastogenesis and osteoblastogenesis, the preference toward bone resorption or formation/repair thus appears to be influenced by the inflammatory microenvironment. When BMP-2 is in a predominately classic inflammatory microenvironment, it tends to promote osteoclastogenesis and when in an alternatively activated microenvironment, BMP-2 induces ostetoblastogenesis. Thus, controlling the microenvironment with IL-10 and/or similar immunoregulatory cytokines may determine the speed and success of BMP-2 mediated bone regeneration, especially under classic inflammatory conditions associated with situations such as infection and multi-tissue trauma.

description: We study a system of fermions in one spatial dimension with linearly confining interactions and short-range disorder. We focus on the zero temperature properties of this system, which we characterize using bosonization and the Gaussian variational method. We compute the static compressibility and ac conductivity, and thereby demonstrate that the system is incompressible, but exhibits gapless optical conductivity. This corresponds to a "Mott-glass" state, distinct from an Anderson and a fully gapped Mott insulator, arising due to the interplay of disorder and charge confinement. We argue that this "Mott-glass" phenomenology should persist to non-zero temperatures.

description: We analyze an abelian gauge model in 3 dimensions which includes massless scalar matter fields. By controlling the trace anomalies with a local dilatation Ward identity, we show that, in perturbation theory and within the BPHZL scheme, the Chern-Simons term has no radiative corrections. This implies, in particular, the vanishing of the corresponding $β$ function in the renormalization group equation.

Quantum effects in amplitude death of coupled anharmonic self-oscillators

description: Coupling two or more self-oscillating systems may stabilize their zero-amplitude rest-state, therefore quenching their oscillation. This phenomenon is termed "amplitude death". Well-known and studied in classical self-oscillators, amplitude death was only recently investigated in quantum self-oscillators [Ishibashi et al., Phys. Rev. E 96, 052210]. Quantitative differences between the classical and quantum descriptions were found. Here, we demonstrate that for quantum self-oscillators with anharmonicity in their energy spectrum, multiple resonances in the mean phonon number can be observed. This is a result of the discrete energy spectrum of these oscillators, and is not present in the corresponding classical model. Experiments can be realized with current technology and would demonstrate these genuine quantum effects in the amplitude death phenomenon.

description: The drive to make the aging electric grid more efficient, reliable, and clean has been at the heart of the “smart grid” mission. Additionally, provisions of the 2007 Energy Independence and Security Act (EISA) and the 2009 American Recovery and Reinvestment Act (ARRA) have led to smart grid investments in the United States. Smart grid upgrades have included the installation of new technologies at all levels of the electric power delivery system. At the distribution system level modernization has included upgrades to communication systems, distribution automation, local control and protection systems, and advanced metering infrastructure (AMI). Chapter 2 of this thesis aims to use elements of the emerging smart grid at the distribution system level to alleviate the effects of a widespread and long-duration power blackout. Despite continuing efforts to make the electric grid robust, some risk remains of widespread and extended power outages caused by extreme weather, human error, or premeditated terrorist attack. Chapter 2 applies the concept of survivability to the case of ensuring the continued provision of a subset of socially critical services during such blackouts. A load cycling based methodology is proposed, and an associated economic analysis indicates that the cost of implementing the proposed scheme constitutes less than 1% of median annual household income for a range of assumed outage probabilities, distributed generation resource availabilities, and financing options. While the technical elements of proposed scheme are largely feasible, a few policy changes are identified as necessary for successful implementation of the scheme. The latter half of this thesis focuses on one potential security risk posed by the large-scale deployment of smart meters. Smart meters constitute one component of advanced metering infrastructure (AMI), a key element of the smart grid. Chapter 3 describes a few documented smart meter hacking strategies and motivates the following question: What, if any, are the implications of smart meter hacking for the bulk power grid? To help answer this question Chapter 4 focuses on one specific attack type with the potential for causing widespread disruption to electric service – the cycling of a large number of consumer loads using the remote connect/disconnect switch on several smart meters. Results from simulations performed on two IEEE test networks (the 9 and 39-bus dynamic test cases) indicate that it is improbable that the mere toggling of customer loads could destabilize the bulk power grid because the fraction of system load that needs to be cycled to induce instability is likely to be prohibitively large.

description: Northland Research, Inc. (Northland) is pleased to submit this proposal for archaeological testing to ComSense, Inc. for the Casa Nueva project. The project area is approximately 4.7 acres. This proposal was solicited by Mark Appleby of ComSense, Inc. as a prelude to obtaining federally guaranteed construction loans for proposed low-income housing to be built in the Casa Nueva project area. Investigation of archaeological resources is a pre condition of obtaining Federal Housing Authority loans (per 36CFR800 Section 106). In addition, test excavations will help determine whether human remains are present. If human remains are present, state statutes (ARS 41­ 844 and 41-865) require that consultation with affiliated Native American groups be conducted to determine the eventual disposition of the remains. Archaeological resources anticipated in the project area include prehistoric habitation and irrigation canals related to the site of La Ciudad and the earliest nineteenth century Hispanic and Anglo occupation along the Salt River. This proposal calls for a stratified random and stratified systematic 2.5 percent sample of the project area and describes how implementation of the fieldwork would search for archaeological resources. Northland’s proposal has three parts. The first section outlines the history of the Casa Nueva area and the evidence that archaeological resources may be present in the project area. The second portion is an outline of the manner in which Northland proposes to investigate the Casa Nueva project area. The final section provides a schedule of the proposed work.

description: We show that depending on the disorder, a small noise added to the threshold distribution of the fuse network may or may not completely change the subsequent breakdown process. When the threshold distribution has a lower cutoff at a finite value and a power law dependence towards large thresholds with an exponent which is less than $0.16\pm0.03$, the network is not sensitive to the added noise, otherwise it is. The transition between sensitivity or not appears to be second order, and is related to a localization-delocalization transition earlier observed in such systems.
