description: Averaged plasma parameters such as electron distribution function and electron density are determined by characterization of high frequency (2.4 GHz) nitrogen-plasma using both experimental methods, namely optical emission spectroscopy (OES) and microphotography, and numerical simulation. Both direct and stepwise electron-impact excitation of nitrogen emissions are considered. The determination of space-resolved electron distribution function, electron density, rate constant for electron-impact dissociation of nitrogen molecule and the production of nitrogen atoms, applying the same methods, is discussed. Spatial distribution of intensities of neutral nitrogen molecule and nitrogen molecular ion from the microplasma is imaged by a CCD camera. The CCD images are calibrated using the corresponding emissions measured by absolutely-calibrated OES, and are then subjected to inverse Abel transformation to determine space-resolved intensities and other parameters. The space-resolved parameters are compared, respectively, with the averaged parameters, and an agreement between them is established.

description: Previous research indicates that sexual disgust is strongly negatively associated with sexual satisfaction. Less is known, however, about how disgust in general affects sexual satisfaction. The present study examined whether individuals with higher perceived vulnerability to disease (PVD) had lower sexual satisfaction in their committed romantic relationships. I also assessed whether mating strategy (long-term vs. short-term dating interests) moderated the association between PVD and sexual satisfaction. I examined these associations through separate analyses for women and men. To answer these questions, I used secondary data that were part of a broader dissertation project. 530 participants’ data were used in which they answered the PVD scale, a sexual satisfaction measure, and a mating strategy measure. Contrary to expectations, there was no significant association between PVD and sexual satisfaction for either sex. Furthermore, mating strategy did not moderate the association between PVD and sexual satisfaction for either sex. While this study found no association between PVD and sexual satisfaction, the question of whether an association between these two variables exists remains unanswered. This may be because the data used were not designed to explicitly examine my study’s research questions. The data used were not ideal in terms of sample composition, available measures, or historical period due to the emergence of COVID-19. Future research should aim to run a study specifically designed to answer these research questions.

Based on which, three topological basis states have been found. And we apply topological basis states to recast nine-dimensional BWMA into its three-dimensional counterpart. Finally, we find the topological basis states are spin singlet states in special case.

Formation of expectations of return to work by injured workers with sub-acute back pain : The role of perceived uncertainty
Creators: name: Stewart, Alison M.
Publisher: name: University of British Columbia
Year: 2010

description: This thesis explores the formation of expectations of return to work from the perspective of injured workers who were off work due to sub-acute back pain. The findings are based on one-to-one semi-structured interviews conducted with injured workers from the Lower Mainland region of British Columbia. Interview data were recorded from 12 participants (6 female, 6 male) between ages 29 and 63 years. Most participants were in receipt of compensation benefits and were recruited through WorkSafeBC. The average duration of work absence was 3 1/3 months. The data were transcribed and analyzed using grounded theory. The findings identified several interactive categories from the data that influence the formation of expectations, including the overarching category of perceived uncertainty, as well as five inter-related sub-categories: (1) perceived lack of control over the return-to-work process, (2) perceived lack of recognition by others of the impact of the injury, (3) perceived inability to perform the pre-injury job, (4) fear of re-injury, and (5) perceived need for workplace accommodations. Perceived uncertainty was determined to be the core category influencing the formation of expectations, which have been identified as an important biopsychosocial element of the return-to-work process. This qualitative study, the first to explore the formation of expectations of return to work, serves to unpack the dynamic, complex and multi-faceted construct of expectations of return to work from the perspective of the injured worker.

description: We study Higgs-radion mixing in a warped extra dimensional model with Standard Model fields in the bulk, and we include a fourth generation of chiral fermions. The main problem with the fourth generation is that, in the absence of Higgs-radion mixing, it produces a large enhancement in the Higgs production cross-section, now severely constrained by LHC data. We analyze the production and decay rates of the two physical states emerging from the mixing and confront them with present LHC data. We show that the current signals observed can be compatible with the presence of one, or both, of these Higgs-radion mixed states (the $ϕ$ and the $h$), although with a severely restricted parameter space. In particular, the radion interaction scale must be quite low, Lambda_ϕ~ 1-1.3 TeV. If m_ϕ~ 125 GeV, the $h$ state must be heavier (m_h>320 GeV). If m_h ~ 125 GeV, the $ϕ$ state must be quite light or close in mass (m_ϕ~ 120 GeV). We also present the modified decay branching ratios of the mixed Higgs-radion states, including flavor violating decays into fourth generation quarks and leptons. The windows of allowed parameter space obtained are very sensitive to the increased precision of upcoming LHC data. During the present year, a clear picture of this scenario will emerge, either confirming or further severely constraining this scenario.

description: Art is such a powerful catalyst for discourse on highly sensitive and polarizing issues. It shows what words cannot, often producing reactions much more potent than any piece of literature could provoke. Camilo Ontiveros’ Temporary Storage is an example of one of these simply efficacious pieces; Since seeing it for the first time almost two years ago, the image of intimate bedroom objects bound by archaic rope has not left my mind. Ontiveros demands attention for a very real issue that thousands of immigrants are facing today: the imminent threat of deportation. In my paper, I will be focusing on the Mexican-American border not as a physical marker, but rather as a cultural divide. Through researching the psychology behind attitudes toward immigration for American citizens, I will uncover how the issue has become so deeply divisive in contemporary society. I plan on highlighting the Mexican immigrant experience primarily through Ontiveros’ piece “Temporary Storage”, although I will touch on another one of his works. As a third born U.S. citizen, the Mexican immigration experience is something I feel a deep interpersonal connection to. Being both Anglo and Hispanic, I often feel stuck between the border: essentialist ideology has driven society toward exclusivity. In actuality, being a child of a mixed-race family is not only taxing in domestic dynamics, but also presents significant moral conflict in the social justice issue of immigration as a whole. Through this paper, I hope to illustrate the realities of Mexican immigrants and present an open discourse on how this influences modern art.

description: In this paper, the author presents a new cryptographic technique, SD-REE, to exclude the repetitive terms in a message, when it is to be encrypted, so that it becomes almost impossible for a person to retrieve or predict the original message from the encrypted message. In modern world, cryptography hackers try to break a code or cryptographic algorithm [1,2] or retrieve the key, used for encryption, by inserting repetitive bytes / characters in the message and encrypt the message or by analyzing repetitions in the encrypted message, to find out the encryption algorithm or retrieve the key used for the encryption. But in SD-REE method the repetitive bytes / characters are removed and there is no trace of any repetition in the message, which was encrypted.

This is done by generalizing the so called ADHM variety. We show that the moduli space of such objects is a quasi projective variety, which is fine in the case of projective spaces. We also give an ADHM categorical description of perverse instanton sheaves in the general case, along with a hypercohomological characterization of these sheaves in the particular case of projective spaces.

description: An overview is given of the way in which the unification program of particle physics has evolved into the proposal of superstring theory as a prime candidate for unifying quantum gravity with the other forces and particles of nature. A key concern with quantum gravity has been the problem of ultraviolet divergences, which is naturally solved in string theory by replacing particles with spatially extended states as the fundamental excitations. String theory turns out, however, to contain many more extended-object states than just strings. Combining all this into an integrated picture, called M-theory, requires recognition of the rôle played by a web of nonperturbative duality symmetries suggested by the nonlinear structures of the field-theoretic supergravity limits of string theory.

description: Since the first international conference on degrowth, the concern of economic, environmental and social crises has been added to political debates. The ideas of going back to village life for the reduction of consumption and having a sustainable life has been presented by many scholars, but with the future shortages of energy, it is not rational to leave the current cities desolated, and to populate new villages. This study strives to conceptualize the village life in cities through rearrangement of urban districts and shared housing systems. Its significance would be to visualize the transforming shape of cities and the human lifestyle in the future where all economic and institutional solutions have progressed, but no exact picture of the new trend has been rendered. This advancement in practice will try to open up an achievable vision to propagate sustainable degrowth in a way that has a less pessimistic message.

description: We present the design and implementation of a trapped ion cavity QED system. A single ytterbium ion is confined by a micron-scale ion trap inside a 2 mm optical cavity. The ion is coherently pumped by near resonant laser light while the cavity output is monitored as a function of pump intensity and cavity detuning. We observe a Purcell enhancement of scattered light into the solid angle subtended by the optical cavity, as well as a three-peak structure arising from strongly driving the atom. This system can be integrated into existing atom{photon quantum network protocols and is a pathway towards an efficient atom{photon quantum interface.

description: Virtual trees are an essential component of many computer generated outdoor scenes. Creation of digital tree models is a difficult and time consuming process requiring specially trained artists and therefore trees are often selected from a library of models. These pre-generated models are expensive, of limited quality and do not suffice when a particular artistic design is required. Moreover, when multiple tree models are combined into scenes, they lack important characteristics of trees that were grown together. My thesis focuses on the development of algorithms and modelling software capable of generating diverse tree forms that are botanically plausible yet easily controlled to meet artistic requirements. I propose a new model of tree growth which enhances the directability and diversity of previous algorithms. A novel multi-touch tablet interface is presented which allows for the free form creation of trees through brushing, pruning and bending of branches into the desired form. Furthermore, I present an algorithm and interface for interactively designing an entire landscape of trees. Neighboring trees exhibit characteristics of being grown together yet they are simulated independently, taking advantage of parallel computing techniques. This ability to easily generate realistic trees and landscapes has applications in the fields of computer graphics and animation, digital landscape design in architectural visualization and computer games.
Blade element analysis and experimental investigation of high solidity wind turbines

description: Water pumping windmills have been used for centuries. The multi-bladed, slowly rotating windpumps developed in the late 1800s are still common all over the world. However their aerodynamic performance is not properly understood because of blade interaction for high solidity operating at very slow speeds. Developing a numerical method to predict and improve performance of water-pumping windmills is essential to allow for design optimization and performance improvement. The choice of the aerodynamic model was made on basis of classical blade element momentum method due to its speed, simplicity and wide acceptance in the wind industry. Blade element theory and momentum theory are combined in this method to predict torque, power and thrust with the inputs of tip speed ratio, blade profile, number of blades and airfoil lift and drag coefficient data. Using blade element momentum theory (BEMT) comes with its own challenges, as certain assumptions do not hold true for high solidity and low speed operating rotors. There is no interaction between two adjacent blades which does not hold true for higher solidity wind turbines. BEMT code was developed by the author and verified with experiments. BEMT was used to characterize the effects of spars and tip loss correction on performance of rotor for six, twelve, twenty four bladed rotor. New tip loss correction was developed for very low speed running wind turbines and compared with BEMT with Prandtl tip loss correction and experiments. Experimental investigation was performed for N=6, 12, 24 bladed rotor configuration using Wegereef [1984] blade profile to get complete performance profile of power, torque and thrust with their coefficients over range of tip speed ratios. Experimental setup was designed and structural analysis was performed by the author to ensure safe operation of the test rig. Monotonic increase in performance parameters was observed in thrust, power and torque for six, twelve, twenty four bladed rotor. From BEMT results it can be concluded that effect of tip loss and blade profile are significant on rotor performance. Although blade profile effects are less than tip loss effects. Solidity effects were found to be very small. BEMT with new tip loss predicted performance are compared with Prandtl's tip loss correction.

description: This supporting paper is a brief description of my earlier work and a reflection of my artistic process during the MFA program. Through the course of these last two years, I have been able to explore ideas of perceptual experience in relation to places. My art practice and theoretical research have reinforced the importance of states of consciousness in the act of perception. During my studies, I learned to attune my senses to phenomenological aspects of light and minute visual processes that can reveal ephemeral moments in everyday life. I found that drawing is an acute exercise of perception; it is a vehicle that allows me to further my understanding about the world around me. Through my final thesis Perceptual Drawing—the last of four—I continued this process of heightening my awareness. These active drawings recorded states of my consciousness and can be viewed as a translation of how I experienced visual perception.
Capturing the memoryscape : alternative visual discourse and the documentaries of Hu Jie and Wang Bing
Creators: name: O'Connor, Marie Nicole
Publisher: name: University of British Columbia
Year: 2010

description: Alternative Chinese film culture has become increasingly diverse since the 1990s. This diversification is related to the kinds of films being produced and to who has ‘the right’ to make and to view them. A significant number of new films are documentaries, distinct in form from the newsreels (xinwen pian) or special topic films (zhuanti pian) that represent the more traditional official forms of documentary. Some of these new unofficial (non-state funded) documentaries have attempted to create alternative space for the telling of individual stories about sensitive and traumatic historical periods such as the Great Leap Forward, the Great Famine, and the Cultural Revolution. Such stories are in marked contrast to official visual histories of these periods. This paper’s focus is the new alternative space created by two individual filmmakers, Hu Jie and Wang Bing, who have documented unofficial, individual histories. Three of their films are examined in the context of a film industry that offers them severely limited or no access at all to official channels of distribution. The paper begins by examining the manner in which historical narratives have been and are ongoingly integral to the construction of a specific official view of the Chinese nation. Such official narratives are dominant in state-run environments, such as schools and in the media, and they tend to drown out any attempted alternative narratives. Hu Jie and Wang Bing stand out, even within alternative film culture, as filmmakers willing to challenge official doctrine and history. The narrative styles of three of their films are closely analyzed with a view to understanding how and why their work differs from that of official historical narratives. The approaches taken by the two filmmakers are also compared and contrasted. A major aspect of this project has been the translation of Hu Jie’s film In Search of Soul of Lin Zhao into English. The other two films examined have already been translated. This paper argues that by privileging the individual narrative, the two filmmakers present more complex versions of traumatic historical periods that stand in contrast to the often idealized or superficial official histories.

description: A ball supported by a spring is set on top of a plate which is sinusoidal vibrated. The motion is limited to one dimension motion. It is assumed that the spring is an ideal one with zero mass. The vibrating plate is considered much heavier than the ball, so that the ball motion has no influence on the plate motion. Plate vibration frequency is varied around the frequency of ball-spring system. Resonance phenomenon is reported, which needs a phase match condition to occur.

description: It has been shown recently that the normal branch of a DGP braneworld scenario self-accelerates if the induced gravity on the brane is modified in the spirit of $f(R)$ modified gravity. Within this viewpoint, we investigate cosmological viability of the Hu-Sawicki type modified induced gravity. Firstly, we present a dynamical system analysis of a general $f(R)$-DGP model. We show that in the phase space of the model, there exist three standard critical points; one of which is a de Sitter point corresponding to accelerating phase of the universe expansion. The stability of this point depends on the effective equation of state parameter of the curvature fluid. If we consider the curvature fluid to be a canonical scalar field in the equivalent scalar-tensor theory, the mentioned de Sitter phase is unstable, otherwise it is an attractor, stable phase. We show that the effective equation of state parameter of the model realizes an effective phantom-like behavior. A cosmographic analysis shows that this model, which admits a stable de Sitter phase in its expansion history, is a cosmologically viable scenario.

description: Location-based social networks (LBSNs) provide a platform for users to share their location information with each other. Location recommendation is the task of suggesting unvisited locations to the users. It aims to make satisfying recommendations of locations by utilizing the information such as users' visiting histories, user profiles and location profiles. This thesis investigates the utilization of check-in data and location category information for location recommendation on LBSNs. A distributed crawler is developed to collect a large amount of check-in data from Gowalla for the research. Then, three ways are used to utilize the check-in data, namely, binary utilization, FIF utilization, and probability utilization. According to different utilizations, different Collaborative Filtering recommenders are introduced to do location recommendation. Experiments are conducted to compare the performances of different recommenders using different check-in utilizations. Location category information is utilized for location recommendation by considering the temporal and spatial patterns. A user's periodic check-in behaviors at different location categories are represented as temporal curves. A temporal influence model is used to predict similar users' check-in behaviors based on temporal curves. A geographical influence model is proposed to filter out locations that are not of interest to the user. By integrating temporal influence and geographical influence a location recommendation algorithm called sPCLR is proposed to recommend locations to the users at a given time of the day. Experimental results show that the sPCLR algorithm performs better than three existing location recommendation algorithms.

description: We investigate different dynamical regimes of neuronal network in the CA3 area of the hippocampus. The proposed neuronal circuit includes two fast- and two slowly-spiking cells which are interconnected by means of dynamical synapses. On the individual level, each neuron is modeled by FitzHugh-Nagumo equations. Three basic rhythmic patterns are observed: gamma-rhythm in which the fast neurons are uniformly spiking, theta-rhythm in which the individual spikes are separated by quiet epochs, and theta/gamma rhythm with repeated patches of spikes. We analyze the influence of asymmetry of synaptic strengths on the synchronization in the network and demonstrate that strong asymmetry reduces the variety of available dynamical states. The model network exhibits multistability; this results in occurrence of hysteresis in dependence on the conductances of individual connections. We show that switching between different rhythmic patterns in the network depends on the degree of synchronization between the slow cells.

description: I used multi-scale entropy (MSE) to quantify brain signal variability in order to examine differences mediated through expertise in visual word recognition (VWR). While, VWR is highly efficient in adult readers, competitive Scrabble players achieve superior performance through extended training. Participants (19 Scrabble experts and 19 controls) performed a lexical decision task (“Is it a word?”) during electroencephalography recording. Behavioural results suggest that Scrabble experts de-emphasize semantic information for lexical decisions, and are faster than controls at processing vertical words. Signal variability results suggest that the variability pattern underlying better Scrabble skill differs between Scrabble experts and controls. Although MSE decreased with higher skill in both groups, the topography of this effect was widespread in the Scrabble group, and sparser in controls. I interpret these findings as the recruitment of extended neural resources driven by long-term practice and a shift in VWR mechanisms with increasing Scrabble skill.

description: We have realized long-lived ground-state polar molecules in a 3D optical lattice, with a lifetime of up to 25 s, which is limited only by off-resonant scattering of the trapping light. Starting from a 2D optical lattice, we observe that the lifetime increases dramatically as a small lattice potential is added along the tube-shaped lattice traps. The 3D optical lattice also dramatically increases the lifetime for weakly bound Feshbach molecules. For a pure gas of Feshbach molecules, we observe a lifetime of >20 s in a 3D optical lattice; this represents a 100-fold improvement over previous results. This lifetime is also limited by off-resonant scattering, the rate of which is related to the size of the Feshbach molecule. Individually trapped Feshbach molecules in the 3D lattice can be converted to pairs of K and Rb atoms and back with nearly 100% efficiency.

description: The study of the charm quark continues to have wide interest as a possible avenue for the discovery of physics beyond the Standard Model and can as well be used as a tool for understanding the non-perturbative aspects of the strong interactions. Owning to the large production cross-section available at the Tevatron collider and to the flexibility of a trigger on fully hadronic final states, the CDF experiment, in a decade of successful operations, collected millions of charmed mesons decays which can be used to investigate the details of the physics of the production and decay processes of the charm quark. Here we present a brief collection of new CDF results on this subject.

description: Today's globalization process requires the training of specialists with intellectual potential, strong knowledge. As you know, any education is built on the basis of a particular social order, and its content, goals and objectives are determined based on this order. In this sense, healthy generation education is also gaining importance in the preschool education system. The article covers the reforms carried out in this system and analyzes the practice of instilling spiritual values in the preschool education system.

description: Analysis of long-term linear flow periods associated with tight/shale gas production has received much attention in recent literature as a means of obtaining information about stimulation efficiency (for example, the product of fracture half-length and square root of permeability referred herein as the linear flow parameter). In this study, first, new methods for analyzing production data from a fractured well in tight/shale gas reservoir producing under a constant flowing pressure, a constant production rate and variable flowing pressure/production rate in the absence or presence of desorption and gas-slippage are presented. It is shown that the current formulation of linear flow analysis results in an overestimation of linear flow parameter for constant flowing pressure production. It is also found that the shape of square-root-of-time plot depends on the production rate for constant gas rate production. Secondly, the effects of completion heterogeneity (i.e., all fracture lengths are not the same) of a multi-fractured horizontal well (MFHW) are studied and a method is developed for extending hybrid forecasting methods developed for homogeneous completions to heterogeneous completions. The methodology developed is also applied for multi-well analysis of MFHWs. It is found that ignoring the heterogeneity of the completion can have a large impact on the long-term forecast of these wells. Thirdly, a new set of dimensionless type curves is developed for one of the most commonly used conceptual models for MFHWs. With these dimensionless type curves, the early linear flow (early-time half slope) and boundary-dominated flow (late-time unit slope) coincide for different geometric ratios and the transition between these two regimes depends on the geometry of the reservoir and completion. Finally, the applicability of flowing material balance (FMB) analysis for calculating contacted gas-in-place (CGIP) in linear-flow dominated systems is investigated. It is found that even when dealing with a gas reservoir that is depleted significantly, FMB underestimates the original gas-in-place (OGIP). We also investigated whether applying a corrected material balance pseudo-time, calculated using the average pressure in the region of investigation as opposed to average reservoir pressure, will correct for underestimation of OGIP for the case that the reservoir is significantly depleted.

description: The occurrence of antiferromagnetism in kappa-(ET)_2X can be understood within an effective 1/2-filled band with dimers of ET molecules containing one hole each. We argue that while this effective model can describe the presence of antiferromagnetism, a complete description for these materials requires the correct carrier density of one-half per molecule. For dimerized and strongly frustrated 1/4-filled lattices we show that a singlet-paired state coexisting with charge ordering occurs that we have termed the Paired Electron Crystal (PEC). Here we investigate the 1/4-filled model on a dimerized lattice, showing regions where AFM, PEC, and the Wigner-crystal occur. We point out the need to go beyond quantum spin liquid concepts for highly frustrated materials such as kappa-(ET)_2Cu_2(CN)_3 and beta'-EtMe_3Sb[Pd(dmit)_2]_2 which we believe are PECs at low temperatures.

description: The precontact subsistence-settlement strategy of Taltheilei tradition groups has been interpreted by past researchers as representing a high residential mobility forager system characterized by ephemeral warm season use of the Barrenlands environment, while hunting barrenground caribou. However, the excavation of four semi-subterranean house pits at the Ikirahak site (JjKs-7), in the Southern Kivalliq District of Nunavut, has challenged these assumptions. An analysis of the domestic architecture, as well as the morphological and spatial attributes of the excavated lithic artifacts, has shown that some Taltheilei groups inhabited the Barrenlands environment during the cold season for extended periods of time likely subsisting on stored resources.

description: MMP9 inhibition increases autophagic flux in chronic heart failure. AmJ PhysiolHeart Circ Physiol 319:H1414–H1437, 2020. First published October 16, 2020; doi:10.1152/ajpheart.00032.2020.—Increased matrix metalloprotease 9 (MMP9) after myocardial infarction (MI) exacerbates ischemia-induced chronic heart failure (CHF). Autophagy is cardioprotective during CHF; however, whether increased MMP9 suppresses autophagic activity in CHF is unknown. This study aimed to determine whether increased MMP9 suppressed autophagic flux and MMP9 inhibition increased autophagic flux in the heart of rats with post-MI CHF. Sprague-Dawley rats underwent either sham surgery or coronary artery ligation 6–8 wk before being treated with MMP9 inhibitor for 7 days, followed by cardiac autophagic flux measurement with lysosomal inhibitor bafilomycin A1. Furthermore, autophagic flux was measured in vitro by treating H9c2 cardiomyocytes with two independent pharmacological MMP9 inhibitors, salvianolic acid B (SalB) andMMP9 inhibitor-I, and CRISPR/cas9-mediatedMMP9 genetic ablation. CHF rats showed cardiac infarct, significantly increased left ventricular end-diastolic pressure (LVEDP), and increasedMMP9 activity and fibrosis in the peri-infarct areas of left ventricular myocardium. Measurement of the autophagic markers LC3B-II and p62 with lysosomal inhibition showed decreased autophagic flux in the peri-infarct myocardium. Treatment with SalB for 7 days in CHF rats decreasedMMP9 activity and cardiac fibrosis but increased autophagic flux in the peri-infarct myocardium. As an in vitro corollary study, measurement of autophagic flux in H9c2 cardiomyocytes and fibroblasts showed that pharmacological inhibition or genetic ablation ofMMP9 upregulates autophagic flux. These data are consistentwith our observations thatMMP9 inhibition upregulates autophagic flux in the heart of rats with CHF. In conclusion, the results in this study suggest that the beneficial outcome ofMMP9 inhibition in pathological cardiac remodeling is in part mediated by improved autophagic flux.

description: Bayesian nonparametric regression with dependent wavelets has dual shrinkage properties: there is shrinkage through a dependent prior put on functional differences, and shrinkage through the setting of most of the wavelet coefficients to zero through Bayesian variable selection methods. The methodology can deal with unequally spaced data and is efficient because of the existence of fast moves in model space for the MCMC computation. The methodology is illustrated on the problem of modeling the oscillations of Cepheid variable stars; these are a class of pulsating variable stars with the useful property that their periods of variability are strongly correlated with their absolute luminosity. Once this relationship has been calibrated, knowledge of the period gives knowledge of the luminosity. This makes these stars useful as "standard candles" for estimating distances in the universe.
