description: We present exact analytical results for the differential conductance of a finite Kitaev chain in an N-S-N configuration, where the topological superconductor is contacted on both sides with normal leads. Our results are obtained with the Keldysh nonequilibrium Green's function technique, using the full spectrum of the Kitaev chain without resorting to minimal models. A closed formula for the linear conductance is given, and the analytical procedure to obtain the differential conductance for the transport mediated by higher excitations is described. The linear conductance attains the maximum value of e2/h only for the exact zero-energy states. Also, the differential conductance exhibits a complex pattern created by numerous crossings and anticrossings in the excitation spectrum. We reveal the crossings to be protected by inversion symmetry, while the anticrossings result from a pairing-induced hybridization of particlelike and holelike solutions with the same inversion character. Our comprehensive treatment of the Kitaev chain allows us also to identify the contributions of both local and nonlocal transmission processes to transport at arbitrary bias voltage. Local Andreev reflection processes dominate the transport within the bulk gap and diminish for higher excited states but reemerge when the bias voltage probes the avoided crossings. The nonlocal direct transmission is enhanced above the bulk gap but contributes also to the transport mediated by the topological states.

description: The project is being done in anticipation of the construction and maintenance of two parallel transmission lines by SRP. As proposed, one is a double circuit 230 kV line with two circuits of 69kV lines underbuilt on the same pole and optical ground wire (OPGW) line running on top of the poles and the second is a double circuit 69kV line with an OPGW running across the top (Grew 2021). In total, the lines will span 8.364 acres of Arizona State Trust lands, near the City of Mesa, Maricopa County, Arizona. The entirety of the project area has been previously surveyed for cultural resources, with the most recent survey occurring in 2001; however, as these projects are now more than ten years old, ASLD is requesting that a new survey be conducted per Arizona State Historic Preservation Office (SHPO) guidance. North Wind, on behalf of SRP, conducted a Class III cultural resources survey of 8.364 acres of ASLD-administered land in support of the proposed Huckleberry Mesa transmission line construction project in Mesa, Maricopa County, Arizona. No cultural resources were identified within the project area; thus, North Wind recommends that the undertaking will result in no effect to historic properties. No additional archaeological investigations are recommended.
The WFIRST Microlensing Survey: Symbiosis with Galactic Bulge studies

description: WFIRST, the Wide Field Infrared Survey Telescope, will be NASA's next flagship astrophysics mission, to follow JWST. In addition to a general observer program, and high-latitude survey to study dark energy, WFIRST will conduct a large microlensing survey of fields in the Galactic bulge in order to explore the demographics of exoplanets as small as Mars in orbits beyond 1 AU. I will give an overview of the WFIRST mission and its microlensing survey, as well as the efforts under way to maximize the return of the microlensing survey. These efforts include a large microlensing survey of the Galactic center using UKIRT, and the development of a new modular population synthesis Galactic model code to keep up with the rapid developments in the understanding of the Galactic bulge.

description: Objective: Genitourinary syndrome of menopause affects up to 50% of postmenopausal women and has negative impacts on the women's quality of life. In this systematic review, we aimed to identify and assess the measurement properties of all existing patient-reported outcome measures (PROMs) specific for genitourinary symptoms that were developed and/or validated for measuring patient-reported outcomes in postmenopausal women. Methods: Studies which evaluated, described, or compared measurement properties of PROMs were considered as eligible. We performed a systematic literature search in MEDLINE, EMBASE, and Web of Science. The methodological quality of each study was assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) Risk of Bias checklist. Furthermore, predefined quality criteria for good measurement properties were applied and the quality of the evidence was graded. Results: Nine articles reporting on four PROMs were included. Two instruments, the Vulvovaginal Symptoms Questionnaire and the Day-to-Day Impact of Vaginal Aging Questionnaire, can be further recommended for use. Both showed moderate to high quality of evidence for sufficient structural validity, internal consistency, and construct validity. The two other instruments, urogenital atrophy quality of life (UGAQoL) and the Urogenital Symptom Scale, cannot be recommended for use, whereby the UGAQoL still has the opportunity to be recommended if the authors gave access to the instrument and further validation studies were conducted. Conclusions: Both Vulvovaginal Symptoms Questionnaire and Day-to-Day Impact of Vaginal Aging Questionnaire can be recommended for use and results obtained with these two instruments can be seen as trustworthy. Future validation studies should focus on those two instruments. Systematic review registration: PROSPERO CRD42018092384

description: The uncertainty principle, which bounds the uncertainties involved in obtaining precise outcomes for two complementary variables defining a quantum particle, is a crucial aspect in quantum mechanics. Recently, the uncertainty principle in terms of entropy has been extended to the case involving quantum entanglement. With previously obtained quantum information for the particle of interest, the outcomes of both non-commuting observables can be predicted precisely, which greatly generalises the uncertainty relation. Here, we experimentally investigated the entanglement-assisted entropic uncertainty principle for an entirely optical setup. The uncertainty is shown to be near zero in the presence of quasi-maximal entanglement. The new uncertainty relation is further used to witness entanglement. The verified entropic uncertainty relation provides an intriguing perspective in that it implies the uncertainty principle is not only observable-dependent but is also observer-dependent.

description: Salt River Project Agricultural Improvement and Power District (SRP) requested North Wind Resource Consulting, LLC (North Wind) conduct a Class III cultural resources resurvey of an approximately 8-mile-long transmission right-of-way along State Route (SR) 87 on Salt River Pima-Maricopa Indian Community (SRP-MIC) land in Maricopa County, Arizona (Figure 1). Emergency repairs and replacements were made to transmission poles within the survey area following a severe monsoon storm, which caused significant damage. The survey was conducted to determine if cultural resources were impacted as a result of the emergency repairs. The survey area consists of the 45.06-acre linear transmission right-of-way along SR 87. Salt River Ordinance 102-86 requires identification and treatment of archaeological resources endangered by proposed construction activities on the SRP-MIC. The project is considered an undertaking requiring compliance with Section 106 of the NHPA, which requires a federal agency to consider the effects of its undertakings on historic properties (cultural resources eligible for listing in the National Register of Historic Places [NRHP]).
Asymptotic Expansions and Amplification of a Gravitational Lens Near a Fold Caustic

description: We propose two methods that enable us to obtain approximate solutions of the lens equation near a fold caustic with an arbitrary degree of accuracy. We obtain "post-linear" corrections to the well-known formula in the linear caustic approximation for the total amplification of two critical images of a point source. In this case, in order to obtain the nontrivial corrections we had to go beyond the approximation orders earlier used by Keeton et al. and to take into account the Taylor expansion of the lens equation near caustic up to the fourth order. Corresponding analytical expressions are derived for the amplification in cases of the Gaussian and power-law extended source models; the amplifications depend on three additional fitting parameters. Conditions of neglecting the correction terms are analysed. The modified formula for the amplification is applied to the fitting of light curves of the Q2237+0305 gravitational lens system in a vicinity of the high amplification events (HAEs). We show that the introduction of some "post-linear" corrections reduces chi^2 by 30% in the case of known HAE on the light curve of image C (1999). These corrections can be important for a precise comparison of different source models with regard for observational data.

description: The walk distances in graphs are defined as the result of appropriate transformations of the $\sum_{k=0}^\infty(tA)^k$ proximity measures, where $A$ is the weighted adjacency matrix of a graph and $t$ is a sufficiently small positive parameter. The walk distances are graph-geodetic; moreover, they converge to the shortest path distance and to the so-called long walk distance as the parameter $t$ approaches its limiting values. We also show that the logarithmic forest distances which are known to generalize the resistance distance and the shortest path distance are a subclass of walk distances. On the other hand, the long walk distance is equal to the resistance distance in a transformed graph.

Quantum Dissension: Generalizing Quantum Discord for Three-Qubit States

description: We introduce the notion of quantum dissension for a three-qubit system as a measure of quantum correlations. We use three equivalent expressions of three-variable mutual information. Their differences can be zero classically but not so in quantum domain. It generalizes the notion of quantum discord to a multipartite system. There can be multiple definitions of the dissension depending on the nature of projective measurements done on the subsystems. As an illustration, we explore the consequences of these multiple definitions and compare them for three-qubit pure and mixed GHZ and W states. We find that unlike discord, dissension can be negative. This is because measurement on a subsystem may enhance the correlations in the rest of the system. This approach can pave a way to generalize the notion of quantum correlations in the multiparticle setting.

The dynamics of 1000 galaxies at z 1-2 as measured from KMOS

description: Using ~60 nights of GTO observations with KMOS, we have measured the dynamics of ~1000 star forming galaxies at z~1-2.  In this talk I will present some of the science highlights from this program, including: (i) how the ISM turbulence evolves with redshift, mass and star formation rate; (ii) the evolution of baryonic angular momentum of early disks, and how this controls the emergence of the Hubble Sequence; and (iii) the relation between baryonic and non-baryonic components in galaxies and how the dark matter fraction evolves with mass and redshift.

description: We study the rate of convergence to a normal random variable of the real and imaginary parts of Tr(AU), where U is an N x N random unitary matrix and A is a deterministic complex matrix. We show that the rate of convergence is O(N^{-2 + b}), with 0 <= b < 1, depending only on the asymptotic behaviour of the singular values of A; for example, if the singular values are non-degenerate, different from zero and O(1) as N -> infinity, then b=0. The proof uses a Berry-Esse'en inequality for linear combinations of eigenvalues of random unitary, matrices, and so appropriate for strongly dependent random variables.

description: At intermediate to high redshifts, measuring galaxy kinematics beyond 1 effective radius is time-consuming even for 10 m-class telescopes (>10 hours per galaxy). This poses a major challenge for future deep spectroscopic galaxy surveys. We introduce a novel strategy to make use of the multi- object spectrograph to improve observation efficiency in deep galaxy kinematic surveys, which is feasible for current major ground-based facilities like VLT and KECK and complementary to ongoing KMOS IFU observations. About one hundred star-forming galaxies at z~1 are observed with the KECK/DEIMOS instrument. Each object is observed with slits in multiple position angles to cover the full galaxy, and with a total of 10-30 hours on source. Rotation curves up to 1-3 effective radii can be constrained from optical emission lines, and the stellar-mass Tully-Fisher relation is presented.  Finally, we discuss whether the turn-over of rotation curves is common for the star-forming galaxies in our sample. This may put constraint on the fraction of baryon-dominated systems at this epoch.
Heat wave impacts across scales in the splash pool copepod, Tigriopus californicus
Creators: name: Siegle, Matthew Ray
Publisher: name: University of British Columbia
Year: 2017

description: Temperature influences biological processes at all levels of biological organization. As such, temperature is a fundamental abiotic variable affecting ectotherm fitness. As human induced climate change persists, the need to understand biological responses to temperature has never been more pressing. One consequence of rapid climate change is an increase in the frequency and intensity of heat waves. Despite substantial interest in the physiological effects of heat stress, it is less clear how individual responses to extreme heat events influence population-level responses such as persistence and population growth. Energy balance is a unifying concept that integrates the effect of temperature across scales. The Energy Limited Tolerance to Stress (ELTOS) framework links physiological models of temperature and oxygen availability to dynamic energy budgets in order to predict the effect of stress on individual reproduction and population growth. Drawing on the ELTOS framework, I tested three critical predictions about individual thermal experience, and how the influence of heat stress scales up from physiological to individual to populations, utilizing the splash pool copepod, Tigriopus californicus. In Chapter 2, I tested the prediction that aerobic energy production declines with increasing heat wave intensity and duration, and that individual reproduction declines similarly. In Chapter 3, I tested the assumption that short-term impacts of heat waves on individual reproduction have persistent effects on longer-term population dynamics. In Chapter 4, I tested for an effect of spatial variation in thermal history on subsequent heat wave survival. Together, these tests provide a comprehensive examination of ELTOS predictions of biological responses to heat waves across scales. My data are consistent with ELTOS predictions that heat wave intensity affects energy balance and subsequent individual reproductive effort. However, I did not find consistent patterns of population dynamics over both short and longer-term time scales. The opposing effect of temperature on different life-history traits that occur over different time-scales likely underlies differences in the effect of short-term heat wave effects on population dynamics over short and longer time periods. Lastly, I found that spatial variation in thermal history, particularly recent heat accumulation, explains reduced survivorship during experimental heat waves.

description: There are varieties of methods available for the exploration of solids using nuclear magnetic resonance (NMR) spectroscopy. Some of these methods are quite sophisticated, others require specialized equipment. This review is addressed to those for whom NMR is not the main research method. It discusses simple methods that can be applied to solids with little or no adaptation to a specific system. Despite their technical simplicity and ease of use, these methods are powerful analytical tools that provide unique insights into the structure, dynamics, and noncovalent interactions in homo- and heterogeneous systems. Particular attention is paid to the characterization of porous materials and solids containing phosphorus. 31P NMR of organometallic compounds has been used as an example of how theoretical calculations can help in deeper analysis of experimental data.

description: End-to-end latency - the time a computer system needs from an input event until output is displayed - directly influences task difficulty and user experience. It is therefore an important topic in HCI research. Different human-computer interfaces require different ways to measure latency as it is influenced by all involved hardware and software components. However, many approaches to measuring latency rely on professional lab equipment and are therefore hard to replicate. We propose a method for accurately measuring the end-to-end latency of traditional setups with a button-equipped input device and a display. To this end, a microcontroller closes the electrical contact of a mouse button to trigger an input event, and captures the screen response via a photo-resistor. Our approach combines parts of different existing methods to measure latency and only relies on cheap and off-the-shelf components to allow for easy replication. The latency values measured by our device are very close to those measured with a high-speed smartphone camera (240 Hz). The maximum error is below 2.64 ms - lower than the camera's temporal resolution and the screen refresh periods of high-fps computer displays. Therefore, our approach allows for repeatedly and reliably measuring end-to-end-latency.

description: We study a simple higher-dimensional toy model of electroweak symmetry breaking, in particular a pure gauge 5D theory on flat background with one extra finite space dimension. The principle of least action and the requirement of gauge independence of scattering amplitudes are used to determine the possible choices of boundary conditions. We demonstrate that for any of these choices the scattering amplitudes of vector bosons do not exhibit power-like growth in the high energy limit. Our analysis is an extension and generalization of the results obtained previously by other authors.

description: An inventory of previously recorded prehistoric and historic archaeological sites in Maricopa County has been prepared by Archaeological Research Services, Inc. (ARS), on behalf of the Maricopa County County Parks and Recreation Department, and with the assistance of a matching grant-in-aid from the U.S. Department of the Interior, National Park Service, administered by the Arizona State Historic Preservation Office of the Arizona State Parks Board. This inventory report identifies and evaluates 2,343 sites in terms of their quality, endangerment status, and ownership, and provides recommendations for the preservation treatment of all sites. Treatment alternatives include the acquisition and protection of sites by public entities, the protection of sites by private landowners, and site documentation through data recovery. Other sites are identified which could be preserved intact through active or passive management procedures; a final category of inventory site requires further evaluation as a basis for determining its need for preservation treatment. In order to improve the effectiveness of cultural resource management and archaeological research activities in Arizona, it has been recommended that a systematic, comprehensive, and readily accessible state-wide site file system be established and that recording institutions and organizations co-operate by submitting existing and new site data for inclusion in this system.

description: We argue that the whole or the part of the phase diagrams of QCD and QCD-like theories should be universal in the large-N_c limit through the orbifold equivalence. The whole phase diagrams, including the chiral phase transitions and the BEC-BCS crossover regions, are identical between SU(N_c) QCD at finite isospin chemical potential and SO(2N_c) and Sp(2N_c) gauge theories at finite baryon chemical potential. Outside the BEC-BCS crossover region in these theories, the phase diagrams are also identical to that of SU(N_c) QCD at finite baryon chemical potential. We give examples of the universality in some solvable cases: (i) QCD and QCD-like theories at asymptotically high density where the controlled weak-coupling calculations are possible, (ii) chiral random matrix theories of different universality classes, which are solvable large-N (large volume) matrix models of QCD. Our results strongly suggest that the chiral phase transition and the QCD critical point at finite baryon chemical potential can be studied using sign-free theories, such as QCD at finite isospin chemical potential, in lattice simulations.

description: In the present work, we reconstruct different f(T)-gravity models corresponding to the original and entropy-corrected version of the holographic and new agegraphic dark energy models. We also obtain the equation of state parameters of the corresponding f(T)-gravity models. We conclude that the holographic and new agegraphic f(T)-gravity models behave like phantom or quintessence model. Whereas in the entropy-corrected models, the equation of state parameter can justify the transition from the quintessence state to the phantom regime as indicated by the recent observations.

Assessing the utility of Airborne Laser Scanning for Terrestrial Ecosystem Mapping
Creators: name: Campbell, Lorraine
Publisher: name: University of British Columbia
Year: 2017

description: Observing landscape patterns at various temporal and spatial scales is central to mapping ecosystems. Traditionally, ecosystem mapping uses a combination of fieldwork and aerial photography interpretation. These methods, however, are time-consuming, prone to subjectivity, and difficult to update. Airborne Laser Scanning (ALS) is an advanced remote sensing technology that has increased in application in the past decade and has the potential to significantly increase and refine information content of ecosystem mapping, especially in the vertical dimension. ALS technology provides detailed information on topography and vegetation structure and has considerable potential to be used for terrestrial ecosystem classification and mapping. In this thesis, the potential to use ALS data to advance ecosystem mapping is examined. The current state of the science for using ALS data to classify and map key ecosystem attributes within an existing ecosystem mapping scheme is discussed by focusing on British Columbia’s Terrestrial Ecosystem Mapping (TEM) and its associated Predictive Ecosystem Mapping (PEM). Based on a detailed literature review, a site-specific case study was also developed with the goal of mapping TEM polygons for a forested landscape on Vancouver Island, British Columbia. To do so an object-based image analysis approach was used. The analysis examined which were the best suite of ALS-based terrain and vegetation metrics to define and distinguish individual site series. It established a workflow for the classification of site series within the study site and examined the capacity to map site series based on ALS derived values. Best segmentation parameters were first established and then the study area was classified for slope position-wetness and finally into the specific site series. In the classification of site series two approaches were used. One approach used only terrain metrics and the other incorporated vegetation metrics. Overall accuracies were 59% and 56% respectively. While this workflow requires refinement, it shows potential for improved accuracies by applying suggestions discussed. The thesis concludes with a discussion summarizing the findings of this research and highlighting future refinement to the methods applied in the case study, while also providing recommendations for the current application of ALS technology to TEM.

description: We are continuing a J, K and narrow-band imaging survey of 300 square degrees of the plane of the Galaxy, searching for new Wolf-Rayet stars. Our survey spans 150 degrees in Galactic longitude and reaches 1 degree above and below the Galactic plane. The survey has a useful limiting magnitude of K = 15 over most of the observed Galactic plane, and K = 14 (due to severe crowding) within a few degrees of the Galactic center. Thousands of emission line candidates have been detected. In spectrographic follow-ups of 146 relatively bright WR star candidates we have re-examined 11 previously known WC and WN stars and discovered 71 new WR stars, 17 of type WN and 54 of type WC. Our latest image analysis pipeline now picks out WR stars with a 57% success rate. Star subtype assignments have been confirmed with K band spectra, and distances approximated using the method of spectroscopic parallax. Some of the new WR stars are amongst the most distant known in our Galaxy. The distribution of these new WR stars is beginning to trace the locations of massive stars along the distant spiral arms of the Milky Way.

description: The description of excited state dynamics in multichromophoric systems constitutes both a theoretical and experimental challenge in modern physical chemistry. An experimental protocol which can systematically characterize both coherent and dissipative processes at the level of the evolving quantum state of the chromophores is desired. In this article, we show that a carefully chosen set of polarization controlled two-color heterodyned photon-echo experiments can be used to reconstruct the time-evolving density matrix of the one-exciton manifold of a heterodimer. This possibility in turn allows for a complete description of the excited state dynamics via quantum process tomography (QPT). Calculations on the dimer show that QPT can reveal rich information about system-bath interactions, which otherwise appear nontrivially hidden in the polarization monitored in standard four-wave mixing experiments. Our study presents a novel method for analyzing condensed phase experiments with a quantum information processing perspective.

Near-Infrared Study of the Galactic Bulge X-ray Emission
Creators: name: Morihana, Kumiko

Year: 2019

description: Apparently diffuse X-ray emission has been known to exist along the Galactic Plane, which is referred to as the Galactic Diffuse X-ray Emission (GDXE). The GDXE is composed of the Galactic Center X-ray Emission (GCXE), Galactic Ridge X-ray emission (GRXE), and Galactic Bulge X-ray Emission (GBXE), and its energy spectra are characterized by ionized Fe-K emission lines. A deep exposure by Chandra on the GBXE resolved >80% of the Fe-K lines into many faint X-ray sources. However, nature of these faint sources is poorly understood due to a lack of X-ray photon statistics. We carried out NIR imaging and spectroscopy of the Chandra field by Subaru/MOIRCS.  Consequently, we found that there seems to be an unexpected stellar population constituting the GBXE, rather ordinary in NIR and unexpectedly shining in X-rays. In this talk, we present these NIR results and discuss nature of the new population in the Galactic bulge.
Scaling Analysis in the Numerical Renormalization Group Study of the Sub-Ohmic Spin-Boson Model

description: The spin-boson model has nontrivial quantum phase transitions in the sub-Ohmic regime. For the bath spectra exponent $0 \leqslant s<1/2$, the bosonic numerical renormalization group (BNRG) study of the exponents $β$ and $δ$ are hampered by the boson state truncation which leads to artificial interacting exponents instead of the correct Gaussian ones. In this paper, guided by a mean-field calculation, we study the order parameter function $m(τ=α-α_c, ε, Δ)$ using BNRG. Scaling analysis with respect to the boson state truncation $N_{b}$, the logarithmic discretization parameter $Λ$, and the tunneling strength $Δ$ are carried out. Truncation-induced multiple-power behaviors are observed close to the critical point, with artificial values of $β$ and $δ$. They cross over to classical behaviors with exponents $β=1/2$ and $δ=3$ on the intermediate scales of $τ$ and $ε$, respectively. We also find $τ/Δ^{1-s}$ and $ε/Δ$ scalings in the function $m(τ, ε, Δ)$. The role of boson state truncation as a scaling variable in the BNRG result for $0 \leqslant s<1/2$ is identified and its interplay with the logarithmic discretization revealed. Relevance to the validity of quantum-to-classical mapping in other impurity models is discussed.

CaT study of Bulge Globular Clusters

Publisher: name: Zenodo
Year: 2019

description: It has been recognized for a long time that our Galaxy contains at least two populations of Globular Clusters: one associated with the halo and the other with Disco/Bulge of the Milky Way (BGC). Both populations strongly trace the chemical and dynamic properties of the respective Galactic components. While the Globular Clusters of the halo have been studied in great detail, the BGC have been relatively neglected, mainly due to the high interstellar reddening. The Vista Variables in the Via Lactea survey (VVV) has been an important advance for the infrared study of the Galaxy's BGC system. However, there are two fundamental parameters of these objects that the VVV can not provide with the required precision: radial velocities (RV) and metallicities. The most efficient way to derive these important parameters is through the near infrared spectroscopic observation of the Ca II Triplet lines (CaT - λ ≈ 8500 Å). In this work, we present results of a sample of BGC studied with the CaT technique, through observations obtained with the FORS2 instrument of the VLT (Chile). Our results not only contribute to the understanding of the distribution of metallicities and kinematics of the BGC system, but will also provide information on targets for future high resolution spectroscopic followup studies, e.g. with CAPOS.
Analogs of noninteger powers in general analytic QCD

description: In contrast to the coupling parameter in the usual perturbative QCD (pQCD), the coupling parameter in the analytic QCD models has cuts only on the negative semiaxis of the Q^2-plane (where q^2 = -Q^2 is the momentum squared), thus reflecting correctly the analytic structure of the spacelike observables. The Minimal Analytic model (MA, named also APT) of Shirkov and Solovtsov removes the nonphysical cut (at positive Q^2) of the usual pQCD coupling and keeps the pQCD cut discontinuity of the coupling at negative Q^2 unchanged. In order to evaluate in MA the physical QCD quantities whose perturbation expansion involves noninteger powers of the pQCD coupling, a specific method of construction of MA analogs of noninteger pQCD powers was developed by Bakulev, Mikhailov and Stefanis (BMS). We present a construction, applicable now in any analytic QCD model, of analytic analogs of noninteger pQCD powers; this method generalizes the BMS approach obtained in the framework of MA. We need to know only the discontinuity function of the analytic coupling (the analog of the pQCD coupling) along its cut in order to obtain the analytic analogs of the noninteger powers of the pQCD coupling, as well as their timelike (Minkowskian) counterparts. As an illustration, we apply the method to the evaluation of the width for the Higgs decay into b+(bar b) pair.
