Mode-coupling and the pygmy dipole resonance in a relativistic two-phonon model

description: A two-phonon version of the relativistic quasiparticle time blocking approximation (RQTBA-2) represents a new class of many-body models for nuclear structure calculations based on the covariant energy density functional. As a fully consistent extension of the relativistic quasiparticle random phase approximation (RQRPA), the two-phonon RQTBA implies a fragmentation of nuclear states over two-quasiparticle and two-phonon configurations. This leads, in particular, to a splitting-out of the lowest 1$^-$ state as a member of the two-phonon $[2^+\otimes3^-]$ quintuplet from the RQRPA pygmy dipole mode, thus establishing a physical mixing between these three modes. The inclusion of the two-phonon configurations in the model space allows to describe the positions and the reduced transition probabilities of the lowest 1$^-$ states in isotopes $^{116,120}$Sn as well as the low-energy fraction of the dipole strength without any adjustment procedures. The model is also applied to the low-lying dipole strength in neutron-rich $^{68,70,72}$Ni isotopes. Recent experimental data for $^{68}$Ni are reproduced fairly well.

description: Motivated by quantum oscillations observed in highly ordered ortho-II YBa_2Cu_3O_6.5, we study the Fermi surface topology of d-density wave (ddw) or antiferromagnetic (AF) ordering in the presence of the ortho-II potential. We find that the electron pocket is unaffected by the presence of the ortho-II potential. This further strengthens the proposal that quantum oscillations observed in ortho-II-free YBa_2Cu_4O_8 arise from an electron pocket. On the other hand, the hole pocket topology is sensitive to the ortho-II potential. We show there exist generically three distinct quantum oscillations associated with one electron-like and two hole-like Fermi pockets. We compare our results to the quantum oscillations observed in experiments. We discuss possible ways to distinguish between ddw and antiferromagnetic orders in a potential single-layer ortho-II material.

description: We present the calculations of the complete next-to-leading order (NLO) QCD effects on the single top productions induced by model-independent $tqg$ flavor-changing neutral-current couplings at hadron colliders. Our results show that, for the $tcg$ coupling the NLO QCD corrections can enhance the total cross sections by about 60% and 30%, and for the $tug$ coupling by about 50% and 20% at the Tevatron and LHC, respectively, which means that the NLO corrections can increase the experimental sensitivity to the FCNC couplings by about 10%$-$30%. Moreover, the NLO corrections reduce the dependence of the total cross sections on the renormalization or factorization scale significantly, which lead to increased confidence on the theoretical predictions. Besides, we also evaluate the NLO corrections to several important kinematic distributions, and find that for most of them the NLO corrections are almost the same and do not change the shape of the distributions.

description: Future e+e- colliders are called to play a fundamental role in measuring Standard Model (SM) parameters with unprecedented precision and the discovery of physics beyond the SM (BSM). This study focus on a QCD-like Hidden Valley (HV) scenario, with relatively light v-quarks, perturbing the QCD partonic cascade and modifying azimuthal and (pseudo)-rapidity correlations of final-state SM hadrons. We assume a collision energy of 240 GeV and we consider an ILD-for-FCC detector to study unexpected structures arising in the two-particle angular correlation function, including selection cuts and detector effects.
Range-Wide Migratory Connectivity of Painted Buntings
Creators: name: Sharp, Andrew J.
Publisher: name: Utah State University
Year: 2021

description: The Painted Bunting (Passerina cirus) is a small (~16g), short/medium-distance migratory songbird that is listed as a species of conservation concern by the US Fish and Wildlife Service. Painted Buntings breed in two distinct populations, one eastern population and one interior population, separated by a 500 km gap that stretches from Mississippi to Georgia. I analyzed tracking data from 112 Painted Buntings from 11 different breeding sites to explore how individuals from different breeding sites differ in wintering location (chapter 2) and migratory timing (chapter 3). Additionally, I examined differences in migratory behavior between male and females in the eastern population (chapter 4). My results reveal that eastern and interior Painted Buntings remain separate throughout the annual cycle. Within each population, individuals from different regions of each population mix extensively on the non-breeding ground. Migratory timing was drastically different between the two populations, with interior Painted Buntings departing the breeding ground two months prior to birds from the eastern population. In eastern Painted Buntings, some variation in fall departure could be attributed to differences in vegetation greenness and temperature, suggesting that eastern birds may adjust their fall departure from year to year in accordance with yearly variation in environmental conditions. Fall departure was not closely linked to environmental conditions in the interior population. I found that eastern Painted Buntings arrive on the breeding ground at approximately the same time each year, suggesting that spring arrival timing may have a strong instinctual component. In eastern Painted Buntings, males arrived on the breeding ground before females, but I found no differences in fall departure timing between the sexes. In the eastern population, females wintered slightly farther north on average than males. This work demonstrates the considerable differences in migratory behavior that are possible within a single species.
Removing Barriers to Language Sample Analysis: Computer-Automated Microstructure Scoring (CAMS)
Creators: name: Fox, Carly
Publisher: name: Utah State University
Year: 2021

description: Language sample analysis (LSA) is an important practice for providing a sensitive and accurate measure of a child’s language abilities. Several research-validated progress-monitoring tools are currently available that are designed to measure language quality through narrative samples in school-age children. While these tools provide clinically important information about a child’s language abilities, they can be time-consuming to code, and challenging to code reliably. In recent years there has been a surge in the use of automated essay scoring (AES) systems for the scoring of high-stakes written assessments, but few programs has been designed to automate clinical assessments. Narrative microstructure, an important indicator of language quality, lends itself to computer automation due to its relatively objective and straightforward assessment. The purpose of the current study was to test the feasibility of developing a series of computer-based rulesets, collectively referred to as CAMS, for automatically scoring narrative microstructure in LSA. CAMS was designed to individually score six microstructure elements related to conjunctions, meta-cognitive and linguistic verbs and sentence elaboration. The accuracy and interrater reliability of CAMS with hand-scores (n = 414) was compared against goldstandard expert scores (n = 50) based on percent overlap and quadratic weighted kappa (QWK). Results indicated that QWK between CAMS and expert-scores was higher than that of hand-scorers on four of the six elements. CAMS also met the literature-based threshold for strong interrater reliability (k > 0.60) for all six elements. CAMS shows promise as a means for automating the scoring of microstructure in LSA and narrative samples.
Data-Driven Recommendation of Academic Options Based on Personality Traits

Publisher: name: Utah State University

description: The choice of academic major and, subsequently, an academic institution has a massive effect on a person’s career. It not only determines their career path but their earning potential, professional happiness, etc. [1] About 40% of people who are admitted to a college do not graduate within six years. Yet, very limited resources are available for students to help make those decisions, and each guidance counselor is responsible for roughly 400 to 900 students across the United States. A tool to help these decisions would benefit students, parents, and guidance counselors.
Various research studies have shown that personality traits affect college choice, but there were no studies or tools to utilize this information. With this research, we validate that the personality traits can be used to classify majors, and subsequently, to recommend college majors to students. We identified a method to make that recommendation with more than 90% accuracy. We also analyzed methods of simplifying the personality traits dimension and identified two techniques that can reduce the input data by half and still maintain over 90% accuracy.
Computational Fluid Dynamics Benchmark Validation Experiment of Plenum-to-Plenum Flow Through Vertical Heated Parallel Channels
Creators: name: Parker, Austin W.
Publisher: name: Utah State University
Year: 2021

description: The next generation of nuclear power plants will have higher efficiency and improved safety, among other benefits; one attractive option is the high temperature gas reactor. An ability to predict the physics that occur within the reactor under normal conditions and accident scenarios is necessary before it receives regulatory licensing for use. The flow through a high temperature gas reactor involves complex interactions of heat transfer, fluids, and solids.
One method for simulating complex fluid dynamics is called Computational Fluid Dynamics. These simulations have already been used to predict the complex fluid flows found in high temperature gas reactors. Predicting the reactor fluid flows, especially during accident scenarios, is paramount for decision making, safety, and regulatory licensing. Using simulations for these purposes requires confidence in the simulation results. One scientific process to establish confidence in Computational Fluid Dynamics results is called validation.
This dissertation describes a validation experiment that was completed to improve confidence in simulations of thermal-fluid flows of mixing jets, similar to those found in high temperature gas reactors. Validation experiments are vital in the process of simulation validation. A new wind tunnel test section with parallel heated channels was built specifically for this validation experiment. The product of this dissertation is a well described system along with archived measurement inputs and outputs for the simulation validation process. A validation experiment for these physics is not currently available.
Statistical Physics and Modeling of Human Mobility

Subjects: FIS/07 Fisica applicata (a beni culturali, ambientali, biologia e medicina)

description: In this thesis, we extend some ideas of statistical physics to describe the properties of human mobility. By using a database containing GPS measures of individual paths (position, velocity and covered space at a spatial scale of 2 Km or a time scale of 30 sec), which includes the 2% of the private vehicles in Italy, we succeed in determining some statistical empirical laws pointing out "universal" characteristics of human mobility. Developing simple stochastic models suggesting possible explanations of the empirical observations, we are able to indicate what are the key quantities and cognitive features that are ruling individuals' mobility. 

To understand the features of individual dynamics, we have studied different aspects of urban mobility from a physical point of view. We discuss the implications of the Benford's law emerging from the distribution of times elapsed between successive trips. We observe how the daily travel-time budget is related with many aspects of the urban environment, and describe how the daily mobility budget is then spent. We link the scaling properties of individual mobility networks to the inhomogeneous average durations of the activities that are performed, and those of the networks describing people's common use of space with the fractional dimension of the urban territory. We study entropy measures of individual mobility patterns, showing that they carry almost the same information of the related mobility networks, but are also influenced by a hierarchy among the activities performed. We discover that Wardrop's principles are violated as drivers have only incomplete information on traffic state and therefore rely on knowledge on the average travel-times. We propose an assimilation model to solve the intrinsic scattering of GPS data on the street network, permitting the real-time reconstruction of traffic state at a urban scale.
Plasmon-mediated superradiance near metal nanostructures

description: We develop a theory of cooperative emission of light by an ensemble of emitters, such as fluorescing molecules or semiconductor quantum dots, located near a metal nanostructure supporting surface plasmon. The primary mechanism of cooperative emission in such systems is resonant energy transfer between emitters and plasmons rather than the Dicke radiative coupling between emitters. We identify two types of plasmonic coupling between the emitters, (i) plasmon-enhanced radiative coupling and (ii) plasmon-assisted nonradiative energy transfer, the competition between them governing the structure of system eigenstates. Specifically, when emitters are removed by more than several nm from the metal surface, the emission is dominated by three superradiant states with the same quantum yield as a single emitter, resulting in a drastic reduction of ensemble radiated energy, while at smaller distances cooperative behavior is destroyed by nonradiative transitions. The crossover between two regimes can be observed in distance dependence of ensemble quantum efficiency. Our numerical calculations incorporating direct and plasmon-assisted interactions between the emitters indicate that they do not destroy the plasmonic Dicke effect.

Canadian housing policy and the future demand for housing : a demographic analysis and a look into the future
Creators: name: Hamilton-Wright, Heather Jane
Publisher: name: University of British Columbia
Year: 2010

description: Between 19.51 and 1971 the population of Canada increased 50 per cent from 14.1 million to 21.5 million. Simultaneous with the increase, significant changes in the composition of the population were occurring. Age distributions shifted as the post-war baby boom matured. The non-family portion of the household stock increased from 13.3 to 18 per cent. Growing proportions of households were locating in the urban areas. However, there has been virtually no attempt to modify Canadian housing policy to better suit the changing population. Home-ownership and the single family dwelling continue to be encouraged. This thesis examines these and other demographic changes and analyses recent projections of the Canadian population in an attempt to determine the suitability of current housing policy in the light of possible future populations. While recognizing the limitations of using projections based on trends, until a better model is provided, this study illustrates the possibility that today's housing policy may be mis-shaping the housing stock for future populations if current trends continue.

description: Satisfiability Modulo Theories (SMT) and SAT solvers are critical components in many formal software tools, primarily due to the fact that they are able to easily solve logical problem instances with millions of variables and clauses. This efficiency of solvers is in surprising contrast to the traditional complexity theory position that the problems that these solvers address are believed to be hard in the worst case. In an attempt to resolve this apparent discrepancy between theory and practice, theorists have proposed the study of these solvers as proof systems that would enable establishing appropriate lower and upper bounds on their complexity. For example, in recent years it has been shown that (idealized models of) SAT solvers are polynomially equivalent to the general resolution proof system for propositional logic, and SMT solvers that use the CDCL(T) architecture are polynomially equivalent to the Res*(T) proof system. In this paper, we extend this program to the MCSAT approach for SMT solving by showing that the MCSAT architecture is polynomially equivalent to the Res*(T) proof system. Thus, we establish an equivalence between CDCL(T) and MCSAT from a proof-complexity theoretic point of view. This is a first and essential step towards a richer theory that may help (parametrically) characterize the kinds of formulas for which MCSAT-based SMT solvers can perform well.

Fuels Inventory and Appraisal in Intermountain Quaking Aspen (Populus tremuloides) Communities
Creators: name: Beales, Janet A.
Publisher: name: Utah State University
Year: 1998

description: Field research was conducted in quaking aspen, Populus tremuloides Michx., communities. Fifty-one plots were established in seven major locations in the Bear River Range of northern Utah. The locations inventoried were divided into two age classes: young aspen (under 70 yr) and old aspen (over 70 yr). Custom fuel models were developed for each age class and the data were analyzed for relationships between fuel loads and other measurable factors, including: basal area, average diameter at breast height (d.b.h.), fuel depth, litter loads, tree regeneration, shrub loads, herbaceous loads, slope, tree height, aspect, percent aspen in the plot, grazing intensity, trees infected with disease, elevation, and stand age.
The computer program BEHAVE, fuels inventory data, and the two customized fuel models were used to predict fire behavior, including: flame length, fireline intensity, rate of spread and heat per unit area.
Young aspen stands and old aspen stands differed significantly for most of the variables studied. The customized fuel models for the young aspen and old aspen also differed, and these fuel models predicted fire behavior in the two aspen age classes.
When fuel loads were compared to the other stand characteristics inventoried for the 51 plots, fuel loads were most strongly correlated with average d.b.h. (P=.005). Fuel loads were also negatively correlated to grazing intensity (P=.024) for the 51 plots. No significant correlations were found between fuel loads and the other variables when analyzed for the seven locations. In general, stand conditions were not-good indicators of fuel loads in aspen communities.
Most important to this study were the differences in the fuel data. When used to develop custom fuel models, the young and old aspen fuel models represented two distinct stand types and predicted different fire behavior. Neither stand type was well represented by Northern Forest Fire Laboratory (NFFL) model 8. The customized fuel models better represent aspen communities in the Bear River Range and should be used by managers for fire behavior predictions.

description: In this paper we consider the problem of tracking the state of a quantum system via a continuous measurement. If the system Hamiltonian is known precisely, this merely requires integrating the appropriate stochastic master equation. However, even a small error in the assumed Hamiltonian can render this approach useless. The natural answer to this problem is to include the parameters of the Hamiltonian as part of the estimation problem, and the full Bayesian solution to this task provides a state-estimate that is robust against uncertainties. However, this approach requires considerable computational overhead. Here we consider a single qubit in which the Hamiltonian contains a single unknown parameter. We show that classical frequency estimation techniques greatly reduce the computational overhead associated with Bayesian estimation and provide accurate estimates for the qubit frequency

description: We generalise the computations of arXiv:0712.2456 to generate long wavelength, asymptotically locally AdS_5 solutions to the Einstein-dilaton system with a slowly varying boundary dilaton field and a weakly curved boundary metric. Upon demanding regularity, our solutions are dual, under the AdS/CFT correspondence, to arbitrary fluid flows in the boundary theory formulated on a weakly curved manifold with a prescribed slowly varying coupling constant. These solutions turn out to be parametrised by four-velocity and temperature fields that are constrained to obey the boundary covariant Navier Stokes equations with a dilaton dependent forcing term. We explicitly evaluate the stress tensor and Lagrangian as a function of the velocity, temperature, coupling constant and curvature fields, to second order in the derivative expansion and demonstrate the Weyl covariance of these expressions. We also construct the event horizon of the dual solutions to second order in the derivative expansion, and use the area form on this event horizon to construct an entropy current for the dual fluid. As a check of our constructions we expand the exactly known solutions for rotating black holes in global AdS_5 in a boundary derivative expansion and find perfect agreement with all our results upto second order. We also find other simple solutions of the forced fluid mechanics equations and discuss their bulk interpretation. Our results may aid in determining a bulk dual to forced flows exhibiting steady state turbulence.

description: We report on our ongoing efforts to develop, implement, and test VR activities for the introductory astronomy course and laboratory. Specifically, we developed immersive activities for two challenging "3D" concepts: Moon phases, and stellar parallax. For Moon phases, we built a simulation on the Universe Sandbox platform and developed a set of activities that included flying to different locations/viewpoints and moving the Moon by hand. This allowed the students to create and experience the phases and the eclipses from different vantage points, including seeing the phases of the Earth from the Moon. We tested the efficacy of these activities on a large cohort (N=116) of general education astronomy students, drawing on our experience with a previous VR Moon phase exercise (Blanco (2019)). We were able to determine that VRbased techniques perform comparably well against other teaching methods. We also worked with the studentrun VR Club at San Diego State University, using the Unity software engine to create a simulated space environment, where students could kinesthetically explore stellar parallax - both by moving themselves and by measuring parallactic motion while traveling in an orbit. The students then derived a quantitative distance estimate using the parallax angle they measured while in the virtual environment. Future plans include an immersive VR activity to demonstrate the Hubble expansion and measure the age of the Universe. These serve as examples of how one develops VR activities from the ground up, with associated pitfalls and tradeoffs.

description: A study of the mobility of n-doped wurtzite III-Nitrides is reported. We have determined the nonequilibrium thermodynamic state of the III-Nitrides systems, driven far away from equilibrium by a strong electric field, in the steady state, which follows after a very fast transient. The dependence of the mobility (which depends on the nonequilibrium thermodynamic state of the sample) on the electric field strength is derived, which decreases with the strength of electric field. We analyzed the contributions to the mobility arising out of the different channels of electron scattering, namely, the polar optic, deformation, piezoelectric, interactions with the phonons, and with impurities. The case of n-InN, n-GaN, and n-AlN have been analyzed: as expected the main contribution comes from the polar-optic interactions in these strongly polar semiconductors. The other interactions are in decreasing order, the deformation acoustic, the piezoelectric, and the one due to impurities.

description: We suggest a new generalization of Pontryagin duality from the category of Abelian locally compact groups to a category which includes all Moore groups, i.e. groups whose irreducible representations are finite-dimensional. Objects in this category are pro-C*-algebras with a structure of Hopf algebras (in the strict algebraic sense) with respect to a certain topological tensor product.

An A4 model for lepton masses and mixings
Creators: name: Morisi, S.
name: Peinado, E.
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We study an extension of the standard model based on the flavor symmetry A4 only. Neutrino Majorana mass terms arise from dimension five operator and charged lepton masses from renormalizable Yukawa couplings. We introduce three Higgs doublets that belong to one triplet irreducible representation of A4. We study the most general A4-invariant scalar potential and the phenomenological consequences of the model. We find that the reactor angle could be as large as 0.03, while the atmospheric mixing angle is close to maximal.

Full-Text and URL Search Over Web Archives

description: Web archives are a historically valuable source of information. In some respects, web archives are the only record of the evolution of human society in the last two decades. They preserve a mix of personal and collective memories, the importance of which tends to grow as they age. However, the value of web archives depends on their users being able to search and access the information they require in efficient and effective ways. Without the possibility of exploring and exploiting the archived contents, web archives are useless. Web archive access functionalities range from basic browsing to advanced search and analytical services, accessed through user-friendly interfaces. Full-text and URL search have become the predominant and preferred forms of information discovery in web archives, fulfilling user needs and supporting search APIs that feed complex applications. Both full-text and URL search are based on the technology developed for modern web search engines, since the Web is the main resource targeted by both systems. However, while web search engines enable searching over the most recent web snapshot, web archives enable searching over multiple snapshots from the past. This means that web archives have to deal with a temporal dimension that is the cause of new challenges and opportunities, discussed throughout this chapter.

Causal optimization method for imaginary-time Green's functions in interacting electron systems

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: We develop a causal optimization method that ensures causality in numerical calculations of Green's functions in interacting electron systems. Our method removes noncausality of numerical data by finding causal functions closest to the data. By testing our method with an exactly calculable model and applying it to practical dynamical mean-field calculations, we find that intermediate-frequency behaviors of Green's functions are determined solely by causality, and noncausal statistical errors are removed very efficiently. Furthermore, we demonstrate that numerical calculations of the physical branch of the Luttinger-Ward functional can be stabilized by ensuring causality of the noninteracting Green's function. Our method and findings provide a basis for improving stability and efficiency of numerical simulations of quantum many-body systems.

Microwave dielectric resonances in TTF-TCNQ
Creators: name: Barry, Charles Patrick
Publisher: name: University of British Columbia
Year: 2010

description: Dielectric resonances in the microwave region 16 to 40 GHz have been observed in single crystals of the highly anisotropic material TTF-TCNQ below 25°K. The application of open-circuit boundary conditions to the dielectric resonator problem is shown to be inappropriate for this material and a tractable alternative theory, which takes external fields into account, is presented. Using this theory, the dielectric modes were analyzed at 4.2°K to obtain the complex dielectric constant εb along the crystallographic b-axis. For four samples studied in detail, the average values for the real and imaginary parts of the dielectric constant are found to be 4200 and 16 respectively at 25 GHz. A frequency dependence of ε’b is found; however, it is not clear whether this frequency dependence is intrinsic to the samples or is due to the approximate nature of the solution. No frequency dependence of ε”b was observed.

description: A theoretical study on the nonlinear transport of holes in the transient and steady state of p-doped 4H-SiC under the influence of high electric fields is presented. It is based on a nonlinear quantum kinetic theory which provides a clear description of the dissipative phenomena that are evolving in the system. The hole drift velocity and the nonequilibrium temperature are obtained, and their dependence on the electric field strength is derived and analyzed.

Big Data Science Over the Past Web

Subjects: subject: Digital Libraries (cs.DL)
subject: FOS: Computer and information sciences

description: Web archives preserve unique and historically valuable information. They hold a record of past events and memories published by all kinds of people, such as journalists, politicians and ordinary people who have shared their testimony and opinion on multiple subjects. As a result, researchers such as historians and sociologists have used web archives as a source of information to understand the recent past since the early days of the World Wide Web. The typical way to extract knowledge from a web archive is by using its search functionalities to find and analyse historical content. This can be a slow and superficial process when analysing complex topics, due to the huge amount of data that web archives have been preserving over time. Big data science tools can cope with this order of magnitude, enabling researchers to automatically extract meaningful knowledge from the archived data. This knowledge helps not only to explain the past but also to predict the future through the computational modelling of events and behaviours. Currently, there is an immense landscape of big data tools, machine learning frameworks and deep learning algorithms that significantly increase the scalability and performance of several computational tasks, especially over text, image and audio. Web archives have been taking advantage of this panoply of technologies to provide their users with more powerful tools to explore and exploit historical data. This chapter presents several examples of these tools and gives an overview of their application to support longitudinal studies over web archive collections.

Electroweak Skyrmions in the HEFT

description: We study the existence of skyrmions in the presence of all the electroweak degrees of freedom, including a dynamical Higgs boson, with the electroweak symmetry being non-linearly realized in the scalar sector. For this, we use the formulation of the Higgs Effective Field Theory (HEFT). In contrast with the linear realization, a well-defined winding number exists in HEFT for all scalar field configurations. We classify the effective operators that can potentially stabilize the skyrmions and numerically find the region in parameter spaces that support them. We do so by minimizing the static energy functional using neural networks. This method allows us to obtain the minimal-energy path connecting the vacuum to the skyrmion configuration and calculate its mass and radius. Since skyrmions are not expected to be produced at colliders, we explore the experimental and theoretical bounds on the operators that generate them. Finally, we briefly consider the possibility of skyrmions being dark matter candidates.
