description: From the present limits on the masses and mixings of fourth family quarks, they are expected to have mass larger than the top quark and allow a large range of mixing of the third family. They could also have different dynamics than the quarks of three families of the Standard Model. The single production of the fourth family up type quark t' has been studied via anomalous production process pp-> t'VX (where V=g,Z,γ) at the LHC with the center of mass energy of 7 and 14 TeV. The signatures of such process are discussed within both the SM decay modes and anomalous decay modes of t' quarks. The sensitivity to anomalous coupling kappa/Lambda=0.004 TeV^(-1) can be reached at sqrt(s)=14 TeV and L_(int)=100 pb^(-1).

description: Deep spectroscopy of the planetary nebula (PN) NGC\,6153 shows that its heavy element abundances derived from optical recombination lines (ORLs) are ten times higher than those derived from collisionally excited lines (CELs), and points to the existence of H-deficient inclusions embedded in the diffuse nebula. In this study, we have constructed chemically homogeneous and bi-abundance three-dimensional photoionization models, using the Monte Carlo photoionization code {\sc mocassin}. We attempt to reproduce the multi-waveband spectroscopic and imaging observations of NGC\,6153, and investigate the nature and origin of the postulated H-deficient inclusions, as well as their impacts on the empirical nebular analyses assuming a uniform chemical composition. Our results show that chemically homogeneous models yield small electron temperature fluctuations and fail to reproduce the strengths of ORLs from C, N, O and Ne ions. In contrast, bi-abundance models incorporating a small amount of metal-rich inclusions ($\sim 1.3$ per cent of the total nebular mass) are able to match all the observations within the measurement uncertainties. The metal-rich clumps, cooled down to a very low temperature ($\sim 800$~K) by ionic infrared fine-structure lines, dominate the emission of heavy element ORLs, but contribute almost nil to the emission of most CELs. We find that the abundances of C, N, O and Ne derived empirically from CELs, assuming a uniform chemical composition, are about 30 per cent lower than the corresponding average values of the whole nebula, including the contribution from the H-deficient inclusions. Ironically, in the presence of H-deficient inclusions, the traditional standard analysis of the optical helium recombination lines, assuming a chemically homogeneous nebula, overestimates the helium abundance by 40 per cent.

Cost-Reducing Optimization Strategies of Electrical Trains

description: Trains are spatio-temporally varying loads. The spatio-temporally varying nature and the regenerative capacity of the trains provide an excellent opportunity for purchasing and selling the same magnitude of power at different times and locations, according to the price of electricity, which also has spatio-temporal variations. This variation is the basis for two new mechanisms for minimizing the cost of electricity utilization in high-speed electrical trains being pursued in this thesis. In the first approach, unlike the traditional approach of minimizing the energy, we aim to minimize the weighted-cost of electrical energy since the cost of the latter varies with the spatio-temporal location of the train. In the second approach, we outline a transaction mechanism between an electrical train and a real-time electrical load such that the cost of electricity utilization by both may be reduced. Conventional approach to transaction is typically based on bulk and unidirectional power flow while this new approach extends it to distributed and bi-directional power flow.
Time-dependent bond-current functional theory for lattice Hamiltonians: fundamental theorem and application to electron transport

description: The cornerstone of time-dependent (TD) density functional theory (DFT), the Runge-Gross theorem, proves a one-to-one correspondence between TD potentials and TD densities of continuum Hamiltonians. In all practical implementations, however, the basis set is discrete and the system is effectively described by a lattice Hamiltonian. We point out the difficulties of generalizing the Runge-Groos proof to the discrete case and thereby endorse the recently proposed TD bond-current functional theory (BCFT) as a viable alternative. TDBCFT is based on a one-to-one correspondence between TD Peierl's phases and TD bond-currents of lattice systems. We apply the TDBCFT formalism to electronic transport through a simple interacting device weakly coupled to two biased non-interacting leads. We employ Kohn-Sham Peierl's phases which are discontinuous functions of the density, a crucial property to describe Coulomb blockade. As shown by explicit time propagations, the discontinuity may prevent the biased system from ever reaching a steady state.

The Problem of an Inclusive Art History: Reconciling the Universal and Particular through Photography
Creators: name: Putnam, Jacki Marie
Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: This thesis addresses the tendency of the representation of the history of cultures that fall outside of the traditional European/American narrative to follow either universalizing or particularizing approaches. The opposing concepts of universalism and particularism not only create tensions between differing ways to view humanity, but also prevent the construction of a truly inclusive and global art historical narrative. While universalism asserts that there are shared elements of humanity uniting us all, it fails to accommodate differences in culture and lived experience. As a result, what is presented as a universal is often exclusive and, therefore, not a true universal. Conversely, while particularism validates these differences, it can be divisive and incomplete through its emphasis on marginalized experiences. When applied to the writing and teaching of art history, both universalist and particularist approaches result in incomplete narratives. Universalist art history, the narrative most often taught at the introductory or undergraduate level, perpetuates the traditional Eurocentric art historical canon and thereby omits marginalized groups or presents them as solely peripheral to the standard canon. Particularist art history focuses solely on these marginalized groups, creating a fragmented narrative that interacts with the traditional canon but is never fully integrated. Thus, in order to create a more inclusive (and truly universal) art historical narrative, it is necessary to find a way to reconcile the two seemingly incompatible approaches of universalism and particularism. Through a series of case studies examining the works of Augustus Le Plongeon, Timothy O'Sullivan, Man Ray, Edward Weston, Morna Livingston, and Gerardo Suter, photographs of indigenous material culture created in colonized and formerly colonized areas are considered through the lens of the writings of G.W. F. Hegel, Slavoj Žižek, and Judith Butler. While the photographs by Le Plongeon, O'Sullivan, Man Ray, and Weston can be clearly categorized as either universalizing or particularizing, the more contemporary photographs by Livingston and Suter suggest attempts to visually realize the synthesis of the universal and the particular, albeit through differing approaches. While Livingston's work follows Butler's concept of cultural translation between competing universals, Suter's work displays attempts at revising the past as a movement towards synthesis, recalling Hegel's concept of the concrete universal. Ultimately, this study finds that both Livingston and Suter fall short of fully reconciling the universal and the particular. However, a combination of the approaches of Suter and Livingston, and thus of Butler and Hegel, appears to be an ideal solution to the task of fully synthesizing the particular into the universal.

description: A quantitative condition is derived to evaluate the monocular accommodation in holographic stereograms. We find that the reconstruction can be viewed as true-3D image when the whole scene is located in the monocular cues area, with compatible monocular cues and binocular cues. In contrast, it reveals incorrect monocular cues in the visible multi-imaging area and the lacking information area. To demonstrate our theoretical predictions, a pupil-function integral imaging algorithm is developed to simulate the mono-eye observation, and a holographic printing system is set up to fabricate the full-parallax holographic stereogram. Both simulation and experimental results match our theoretical predictions.

Subjects: Uncategorized

description: A model for class of bipartite graphs is introduced, and a certain type of perfect matching, called an acyclic matching, is defined to imply a nonvanishing determinant for a class of weighted biadjacency matrices. Using the existence results in matching theory, an old linear algebra problem on the removable sets of monomials from a generic homogenous polynomial through linear changes in its variables is discussed. The matching property defined in Zn is first generalized to abelian groups and later to arbitrary groups. The local matching property is defined to give alternative proofs for existing results in matching theory. Linear analogues of results concerning matchings in groups are formulated and proven. Finally, an improvement of the fundamental theorem of algebra is given as an application of matchings in field extensions.
The effect of mode of nursing care delivery and skill mix on quality and patient safety outcomes
Creators: name: Havaei, Farinaz
Publisher: name: University of British Columbia
Year: 2017

description: Aims: This study examined the effect of various components of a model of nursing care delivery, the mode of nursing care delivery and nursing skill mix on (a) quality of nursing care (i.e., nurse reported quality of nursing care and nursing tasks left undone), (b) patient adverse events, and (c) nurse outcomes (i.e., job satisfaction and emotional exhaustion) after controlling for nurse demographic characteristics, work environment and workload factors. This study also explores the moderating effects of mode of nursing care delivery and skill mix on the relationship between workload factors and the five outcome variables. Background: Research into redesigning care delivery has typically focused on only one care delivery component at a time (e.g., skill mix). There exists little research focusing on both components, and controlling for one factor while the other is investigated to determine quality of nursing care delivery and nurse and patient outcomes. Method: This cross-sectional exploratory correlational survey study drew upon secondary data from 416 direct care registered nurses (RNs) from medical-surgical settings. Results: Nurses working in a team-based mode of care delivery reported a greater number of nursing tasks left undone compared to those working in a total patient care mode of delivery. Nurses working in a skill mix with licensed practical nurses (LPNs) reported a higher frequency of patient adverse events compared to those working in a skill mix without LPNs. Two moderating effects were found. At higher levels of acuity, nurses in a team-based mode of care delivery reported a higher frequency of patient adverse events than did nurses in a total patient care mode of delivery. At higher levels of acuity, nurses working in a skill mix with LPNs reported lower levels of emotional exhaustion than nurses in a skill mix without LPNs. Conclusion: Models of nursing care delivery components influenced quality and safety outcomes. Implications: To be effective, a team-based mode of care delivery requires collaborative teamwork. Policy makers, administrators and healthcare providers should work together to clarify and optimize the scopes of practice for RNs and LPNs.

description: In this paper we discuss quantization of the Fayet-Iliopoulos parameter in supergravity theories with altered nonperturbative sectors, which were recently used to argue a fractional quantization condition. Nonlinear sigma models with altered nonperturbative sectors are the same as nonlinear sigma models on special stacks known as gerbes. After reviewing the existing results on such theories in two dimensions, we discuss examples of gerby moduli `spaces' appearing in four-dimensional field theory and string compactifications, and the effect of various dualities. We discuss global topological defects arising when a field or string theory moduli space has a gerbe structure. We also outline how to generalize results of Bagger-Witten and more recent authors on quantization issues in supergravities from smooth manifolds to smooth moduli stacks, focusing particular attention on stacks that have gerbe structures.

Subjects: Uncategorized

description: Because of the scientific challenges of space explorations, several space agencies are involved in the design of autonomous planetary surface exploration devices. Examples are Mars rovers, designed with the goal of collecting terrain information, including dust, soil, rocks, and liquids. The design of such sophisticated rovers can be enhanced by less reliance on trial-and-error process, building expensive physical models, and time-consuming experimental testing. Physics-based virtual prototyping is necessary for an efficient and credible Mars rover designs. In this thesis, a new flexible multibody system (MBS) rover model for planetary exploration is developed. Because the rover, a wheeled robot, must be designed to negotiate uneven terrains, the airless wheels must be able to adapt to different soil patterns and harsh operating and environmental conditions. In order to describe accurately the airless-wheel complex geometry and capture its large deformations and rotations, the absolute nodal coordinate formulation (ANCF) finite elements are used. A numerical study is performed to compare the ANCF kinematics and tractive force results with the results of the discrete brush tire model, widely used in the vehicle-dynamics literature. Several simulation scenarios are considered, including a drop test and acceleration along a straight line. The numerical results obtained are verified using data published in the literature and are used to evaluate the accuracy and computational efficiency of the ANCF airless-tire modeling approach.

description: We use series expansion techniques for analyzing properties of the phase transition between the Mott insulating and superfluid phase for bosons on the kagome lattice, and the multicritical point in the ground-state phase diagram for unit-filling is calculated. It is seen that of the clusters that contribute with non-zero weights to the ground state energy, many contain rings. The decay exponents of ground state correlations are also obtained within the Mott phase. For single-particle excited states, quasiparticle dispersion and effective masses for particles and holes are computed along certain symmetry cuts in the first Brillouin zone. Furthermore at eighth order, the coherence-length critical exponent is found to be comparably close to that of the 3D XY model.

Alternate Day Fasting Combined with A Low Carbohydrate Diet for Weight Loss and Weight Maintenance

Publisher: name: University of Illinois at Chicago
Year: 2020

description: This study investigated the effects of alternate day fasting (ADF) combined with a low carbohydrate diet on body weight and metabolic disease risk factors in adults with obesity. Changes in appetite were also evaluated. ADF regimens include a “feast day” where food is consumed ad-libitum over 24 h, alternated with a “fast day” where intake is limited to ~600 kcal over 24 h. Subjects with obesity (n = 31) participated in an ADF diet (600 kcal “fast day” alternated with an ad libitum “feast day”) with a low carbohydrate background diet (30% carbohydrates, 35% protein, 35% fat). The 6-month trial consisted of a 3-month weight loss period followed by a 3-month weight maintenance period. Results from this study show that body weight decreased by 5.5% during the weight-loss period (month 0-3) and remained stable during the weight maintenance period (month 4-6). Net weight loss by month 6 was 6.3%. The ADF low carbohydrate diet produced significant reductions in fat mass, total cholesterol, LDL cholesterol, systolic blood pressure, and fasting insulin. However, lean mass, visceral fat mass, HDL cholesterol, triglycerides, diastolic blood pressure, heart rate, fasting glucose, insulin resistance (measured via HOMA-IR), and HbA1c remained unchanged. Moreover, subjective hunger and fullness did not change during the weight loss period, or the weight maintenance period. These findings suggest that ADF combined with a low carbohydrate diet is effective for weight loss, weight maintenance, and improving certain metabolic disease risk factors such as LDL cholesterol, blood pressure, and fasting insulin. This diet, however, has little impact on subjective appetite. While these preliminary findings are promising, they still require confirmation by a larger‐scale randomized control trial.
The use of cheminformatics methods for predicting adverse drug responses by human androgen receptor
Creators: name: Paul, Naman
Publisher: name: University of British Columbia
Year: 2017

description: The human Androgen Receptor (AR) is a ligand-activated transcription factor that plays a pivotal role in the development and progression of prostate cancer (PCa). AR is also critical for the survival of many forms of castration resistant prostate cancer (CRPC). The currently used AR inhibitors (anti-androgens) face clinical limitations as drug resistance has been reported in patients, both primary and acquired. In 20% of the CRPC patients resistance to AR antagonists arise due to the mutations in the androgen binding site (ABS) of the receptor. Some mutations can convert antagonist to agonist. Such gain-of-function mutations have been reported across the length of the ligand binding domain (LBD) of AR that contains the ABS, it is imperative to develop a prognostic personalized therapy platform which would equip clinicians with actionable strategies in regard to previously unreported AR aberrations when they are encountered in clinical samples. The goal of this study is to develop a theoretical approach that can characterize such previously unreported AR mutants and predict their response to the currently used anti-androgens. Thus, a novel ‘in-silico’ pipeline has been created that amalgamates the state-of-the-art cheminformatics methods with experimental assays that enable predicting AR mutants and characterizing their drug responses with high accuracy. The corresponding pipeline utilizes QSAR approach that extracts key protein-ligand interactions quantified by the in-house developed 4D-inductive molecular descriptors. The developed QSAR models reach about 90% accuracy that forecasts agonist or antagonist behaviors of AR mutants caused by clinically used and experimental anti-androgens. Furthermore, a previously unreported mutant, T878G has been predicted to be activated by both first and second generation anti-androgens and the corresponding experimental evaluation confirmed this prediction. Finally, the applicability and adaptability of the developed cheminformatics pipeline was tested against an experimental anti-androgen drug ODM-201 which was not a part of the QSAR training dataset, and the predictions were confirmed by experimental evaluations. Overall, the developed pipeline can provide useful insights towards understanding the changing genomic landscape of advanced PCa.

description: The potential of silicon nanowires (SiNWs), (diameter < 10 nm) to transform into rigid bundle-like structures with distinct phonon confinement under high pressure (<= 15 GPa), instead of amorphising as per previous reports, is demonstrated using in-situ Raman spectroscopy. The newly observed splitting of the second order transverse optical (2TO) Raman mode into 2TO(L) and 2TO(W) phonon modes at >= 5 GPa establishes a highly anisotropic and mode-dependent pressure response of these SiNWs. Properties of the novel structures are superior compared to other nano-structured silicon and bulk-Si in terms of increased linear modulus, more localized phonon confinement and less anharmonicity.

Publisher: name: University of British Columbia

description: Connected vehicles are on the cutting edge of automotive technology with applications expected to improve mobility and safety. Several studies have evaluated the mobility benefits of connected vehicle technology but there is little research on its impact on safety. The first objective of this study is to investigate the ability to evaluate the safety of a connected vehicle applications using surrogate safety measures through a combination of the micro-simulation model VISSIM and the Surrogate Safety Assessment Model (SSAM). Two connected vehicle applications are reviewed, considering two types of connected vehicle communications, specifically Vehicle-to-Vehicle and Vehicle-to-Infrastructure. The two applications are a cumulative travel time (CTT) intersection control algorithm connected vehicle environment, and a cooperative adaptive cruise control (CACC) application, facilitating vehicle platooning on a freeway. The CACC study investigates the improvement to the freeway segment through a simulated incident. The CTT study investigates the impacts of calibrating the micro-simulation model using real-world vehicle trajectory and conflict data. The CTT algorithm is applied to a signalized intersection and evaluated under three calibration scenarios: uncalibrated, first step calibrated for desired speed and vehicle arrival types, and second step calibrated for conflicts observed in the field. In both studies, a comparison of safety based on the number of conflicts at different time-to-collision thresholds is provided for the varying scenarios. Results show that the combination of VISSIM and SSAM provide an appropriate tool to use in the evaluation of changes in the level of safety of connected vehicle applications, specifically the CACC application and the CTT intersection control application. Calibration of the micro-simulation model has a significant impact on the results of the safety evaluation. However, it is inconclusive whether the results are realistic with the lack of a real-world connected vehicle implementation.

description: Objective- Researchers are continuing to recognize the health impacts resulting from exposure to environmental chemicals and toxicants. The objective of this study is to assess the association between arsenic in drinking water and gestational diabetes. Data in this study were obtained from the Safe Drinking Water Information System (SDWIS) and using birth certificates in the state of Ohio between 2006 – 2008. Methods- Logistic regression generalized estimating equations (GEE) models were used to assess the association between arsenic in drinking water and gestational diabetes. A sensitivity analysis was performed by restricting to counties where less than 10% of residents rely on private well water. Results- The odds ratio for the crude association between average yearly arsenic concentrations and gestational diabetes modeled dichotomously was 0.98 [0.95 – 1.01]. After adjusting for covariates, this estimate slightly changed to 0.99 [0.99 – 1.00]. Results from the sensitivity analysis did not differ much from the crude and fully adjusted models. Conclusion- It was found in this study that the current MCL of 10 μg/L for arsenic concentrations in drinking water is not associated with an increased risk and may even be protective against gestational diabetes. Maternal education was found to significantly modify the association between mean annual arsenic concentrations (μg/L) and gestational diabetes.
Measurement of inclusive jet and dijet cross sections in proton-proton collisions at 7 TeV centre-of-mass energy with the ATLAS detector

description: Jet cross sections have been measured for the first time in proton-proton collisions at a centre-of-mass energy of 7 TeV using the ATLAS detector. The measurement uses an integrated luminosity of 17 nb-1 recorded at the Large Hadron Collider. The anti-kt algorithm is used to identify jets, with two jet resolution parameters, R = 0.4 and 0.6. The dominant uncertainty comes from the jet energy scale, which is determined to within 7% for central jets above 60 GeV transverse momentum. Inclusive single-jet differential cross sections are presented as functions of jet transverse momentum and rapidity. Dijet cross sections are presented as functions of dijet mass and the angular variable $χ$. The results are compared to expectations based on next-to-leading-order QCD, which agree with the data, providing a validation of the theory in a new kinematic regime.

description: Starting from the T-Q equations of the open spin-1 XXZ quantum spin chain with general integrable boundary terms, for values of the boundary parameters which satisfy a certain constraint, we derive a set of nonlinear integral equations (NLIEs) for the inhomogeneous open spin-1 XXZ chain. By taking the continuum limit of these NLIEs, and working in analogy with the open spin-1 XXZ chain with diagonal boundary terms, we compute the boundary and the Casimir energies of the corresponding supersymmetric sine-Gordon (SSG) model. We also present an analytical result for the effective central charge in the ultraviolet (UV) limit.

The Electrophysiology of Stroke: The Role of Glutamate Antiporter, System xc-, in the Ischemic Cascade

description: Ischemic stroke remains the third leading cause of death and leading cause of adult disability worldwide. Efforts to reduce stroke severity, however, have been plagued by translational failure due to gaps in our understanding of cellular mechanisms leading to brain damage after metabolic insult. Loss of blood supply to brain tissue (ischemia) depletes neurons of energy (ATP), which induces an excitatory effect in the synaptic network marked by the excessive release of glutamate. Within minutes, this excitation results in irreversible tissue damage triggered by anoxic depolarization (AD) - an electrophysiological event with predictive value for stroke outcome. Importantly, much of the “ischemic cascade” can be reproduced by transient deprivation of O2 to in vitro hippocampal slices. Using a battery of electrophysiological assays, we reveal several modifiable steps of the ischemic cascade. First, adenosine release during oxygen deprivation does not extend AD in CA1 of hippocampus, while antagonism of glutamate receptors does. Moreover, intact feedforward connections from CA3 contribute to the timing of AD in CA1 insomuch that glutamate expulsion in CA3 propagates AD from CA3 to CA1. System xc-, the cystine/glutamate antiporter, mediates ambient extracellular glutamate levels in the hippocampus, however, its influence during acute ischemia remains unexplored and enigmatic. We therefore compared hippocampal slices from wild type (WT) and xCT-KO (xCT-/-) mice to investigate the role of system xc- during oxygen deprivation. Our results show that both genetic deletion and pharmacological antagonism of system xc- increase latency to AD and attenuate depolarizing waves. This suggests that anoxia-induced excitation in the synaptic network is enhanced due to the antiporter’s putative effect on extracellular glutamate levels. Experiments where extracellular glutamate concentrations were manipulated, as well as experiments performed in conditions of glutamate receptor antagonism, further confirm this hypothesis. These data reveal that the antiporter is a salient driver of the ischemic cascade. Furthermore, after graded hypoxic episodes, xCT-/- mice display accelerated rate of recovery and post-hypoxic potentiation, which are likely functions of enhanced intracellular calcium. Taken together, our findings implicate system xc- as a regulator of ischemia tolerance and an attractive target for the amelioration of stroke pathology.

description: We apply gain/loss to honeycomb photonic lattices and show that the dispersion relation is identical to tachyons - particles with imaginary mass that travel faster than the speed of light. This is accompanied by PT-symmetry breaking in this structure. We further show that the PT-symmetry can be restored by deforming the lattice.

description: his paper begins with the hypothesis that high levels of corruption can self?perpetuate on occasions, as the phenomenon of corruption is perpetrated through all societal levels and sectors. The loss of ethical standards, lack of honest and cohesive leadership, organisational gaps and weaknesses and individual or group greed, coupled with political, or organisational opportunities, and immunity of offenders, are some of the fundamental roots leading to corruption. High levels of corruption have serious negative repercussions for the present and future of any country especially when it occurs in the public sector. Corruption deters investment in the country, as private investment can be discouraged. The consequences are particularly dire in the case of Foreign Direct Investments (FDI), where corruption can amount to an additional cost. It reduces GDP growth as it harms international trade; negatively affects the inflation and exchange rates; affects prices of either imports or exports, thus influencing trade volumes and trade patterns; influences and distorts consumption patterns; increases the wealth distribution disparity and affects the country’s consumption patterns; leads to resource misallocations; harms a county’s international reputation; reduces efficiency, innovation and competition throughout the economy; causes waste of capacity and money, and biases the allocations capital and talent. Finally, it increases inequality as it is instrumental in lowering employment, deters fixed investment as well as becoming a serious hurdle in the establishment of new businesses. The focus of this contribution is on public sector corruption.
Magnetic Field Induced Quantum Criticality via new Asymptotically AdS_5 Solutions

description: Using analytical methods, we derive and extend previously obtained numerical results on the low temperature properties of holographic duals to four-dimensional gauge theories at finite density in a nonzero magnetic field. We find a new asymptotically AdS_5 solution representing the system at zero temperature. This solution has vanishing entropy density, and the charge density in the bulk is carried entirely by fluxes. The dimensionless magnetic field to charge density ratio for these solutions is bounded from below, with a quantum critical point appearing at the lower bound. Using matched asymptotic expansions, we extract the low temperature thermodynamics of the system. Above the critical magnetic field, the low temperature entropy density takes a simple form, linear in the temperature, and with a specific heat coefficient diverging at the critical point. At the critical magnetic field, we derive the scaling law s ~ T^{1/3} inferred previously from numerical analysis. We also compute the full scaling function describing the region near the critical point, and identify the dynamical critical exponent: z=3. These solutions are expected to holographically represent boundary theories in which strongly interacting fermions are filling up a Fermi sea. They are fully top-down constructions in which both the bulk and boundary theories have well known embeddings in string theory.

Limits of Foliations in Quasi-Fuchsian Manifolds

description: We study the asymptotic behavior of certain foliations of ends of quasi-Fuchsian manifolds. We introduce a class of such foliations, which we call asymptotically Poincaré families as they are asymptotic to a family of surfaces determined naturally by the Poincaré metric on the Riemann surface at infinity. We prove the limiting behavior of any asymptotically Poincaré family is completely determined by the geometry of the quasi-Fuchsian manifold M and the conformal structure on the ideal boundary of M. As an application of these results we establish a conjecture of Labourie regarding the asymptotic behavior of the k-surface foliation he constructs. We also show that the constant mean curvature foliation of Mazzeo and Pacard forms an asymptotically Poincaré family and so we can describe its asymptotics as well.
