description: We implement dynamical decoupling techniques to mitigate noise and enhance the lifetime of an entangled state that is formed in a superconducting flux qubit coupled to a microscopic two-level system. By rapidly changing the qubit's transition frequency relative to the two-level system, we realize a refocusing pulse that reduces dephasing due to fluctuations in the transition frequencies, thereby improving the coherence time of the entangled state. The coupling coherence is further enhanced when applying multiple refocusing pulses, in agreement with our $1/f$ noise model. The results are applicable to any two-qubit system with transverse coupling, and they highlight the potential of decoupling techniques for improving two-qubit gate fidelities, an essential prerequisite for implementing fault-tolerant quantum computing.
Microfluidic technology for high-throughput single cell gene expression analysis
Creators: name: White, Adam
Publisher: name: University of British Columbia

description: Transcription measurements with single cell resolution are critical to understanding variable responses in immunity, measuring stochastic noise in gene expression, and assessing the disease and developmental state of heterogeneous populations. The latter is particularly important in stem cell science, developmental biology, and cancer, where minority cells may be most significant. To see these populations requires the quick and cost-effective measurement of hundreds to thousands of individual cells. Quantitative real-time polymerase chain reaction (RT-qPCR) is a sensitive method for quantitative analysis of transcript levels that provides excellent sensitivity and dynamic range in the detection of transcripts. However, the use of RT-qPCR is generally limited to ensemble measurements of bulk cells or plasma, and is blind to minority cell populations. This aggregation obscures the underlying biological response and variability. To address this limitation, we exploit recent advances in scalable microfluidics to develop robust lab-on-chip technology capable of highly parallel and cost-effective measurements of transcript levels from single cells. The microfluidic device integrates single-cell capture, lysis, reverse transcription of contained RNA, and precise measurement of cDNA using RT-qPCR. We demonstrate this system in the study of microRNA expression in a cell line representing chronic myelogenous leaukemia, pluripotency markers in differentiating human embryonic stem cells, and the detection of somatic mutations in a primary breast cancer sample. The ability to screen isolated cells by simultaneously measuring the fraction of cells expressing a specific gene and quantifying the abundance of expression, may provide a new modality for the early detection of disease such as cancer.

description: A novel digital null-beamforming method has been introduced for the selective attenuation of interfering broadband plane waves based on their spatial direction of arrival in 3D spatio-temporal applications. For this purpose, a transfer function and a signal flow graph for a highly selective second-order broadband 3D Beam Notch filter have been proposed. It has been shown that the broadband 3D Beam Notch filter is capable of recovering 3D plane wave signals of interest in the presence of interfering broadband 3D plane waves of signal-to-interference ratios of approximately -20dB. Among the envisaged applications of the 3D Beam Notch filter is the attenuation of broadband radio-frequency interference plane waves in radio astronomy, selectively, based on the spatial direction of arrival while recovering the signals of interest.

description: Spatial representations are crucial when people interact with the physical environment. For example, geographic maps are one of the primary sources for way-finding, spatial planning and navigational activities. Recent technological advancements enable the evolution of current 2D interactive spatial representations of the maps to physical 3D interactive representations using techniques such as 3D printing and mixed reality interaction. In this thesis, we undertake the task of designing collaborative spatial interaction techniques for physical representation of maps. We designed interfaces for the following application scenarios: collaborative terrain navigation, petroleum-well planning, and remote unmanned aerial vehicle (UAV) control. We present our research, encompassing three prototypes we designed and implemented: Shvil, an augmented reality interface for collaborative terrain navigation; PlanWell, a spatial user interface for collaborative petroleum well planning; and Flying Frustum, a spatial interface for enhancing human-UAV awareness.

description: Tone mapping algorithms are utilized to adapt wide dynamic range (WDR) images to limited dynamic range (LDR) displays while maintaining the images’ details. This thesis presents an analog current mode implementation that will realize an exponent-based tone mapping algorithm, including both global and local operators in the imager array periphery. It also presents a one-pass automatic exponent-based tone mapping algorithm and its associated current mode circuit implementation that was designed to avoid manual tuning needed in a previous implementation. Both of these two implementations, designed in 0.35 µm complementary metal oxide semiconductor (CMOS) technology, were simulated and tested in order to evaluate their quality. Objective assessments and detailed comparisons show that the low power and low area features of these hardware implementations make them good choices for low power and low area WDR display applications.

Evolution of Large-Scale Structures in the Wake of Sharp-Edge Thin Flat Bodies

description: This thesis describes computational fluid dynamic study of the wake behind thin flat plates at Reynolds numbers large enough for the formation of energetic structures and turbulence. The dynamically rich behavior of unsteady turbulent wake of bluff bodies consists of energetic and large-scale structures generated through flow instabilities, which have an anisotropic and geometry dependent topology. Large eddies are most important in characterizing the wake and provide the largest contribution to kinetic energy. The three-dimensional wake of thin flat plates positioned normal to a uniform flow is evaluated using Direct Numerical Simulations and Large Eddy Simulations. The flow around a 2D plate is examined at Re = 1200 and 2400 to characterize the wake and establish the dynamics of vortex formation and detachment processes. This is extended to the wake of finite aspect ratio (3D) thin flat plates at Re = 1200. The aspect ratios investigated are 3.2, 1.6 and 1.0. Flow topology eduction is carried out by examining the temporal evolution of aerodynamic forces and their phase-angles, as well as velocity and vorticity fields. Large-scale structures are investigated based on their topology, contributions to turbulent kinetic energy, and interaction with the surface pressure. The educed structures in the wake of 2D plates belong to three distinct regimes (H for high-, L for low-, and M for moderate-intensity vortex shedding) determined from periodicity of vortex shedding based on lift and drag fluctuations. The characteristics of previously identified H and L regimes were quantified, while introducing a new regime M. Formation and distortion of spanwise vortex rollers and streamwise vortex ribs coupled with Reynolds stress anisotropy and compression or stretching of the recirculation region characterize main differences among these regimes. The introduction of additional shear layers significantly alters the flow topology and vortex shedding process for 3D plates compared to 2D plates. Vortices are formed on longer edges of the plate, whereas shear layers on the shorter sides are carried away by the induced streamwise flow. This results in a single vortex shedding process. The vortex “peel-off” on shorter edges fixes the vortex detachment at sharp corners of the plate.
Is CGCS 5926 a symbiotic X-ray binary?

description: We here report on multiwavelength (X-ray to optical) followup observations of carbon star CGCS 5926. These were motivated by the fact that this star is positionally coincident with a faint X-ray emitting object belonging to the ROSAT catalog of sources, thus suggesting a possible symbiotic X-ray binary (SyXB) nature for it. Our spectrophotometric optical data confirm the giant carbon star nature of the object and allow us to classify its spectral type as C(6,2). This classification places CGCS 5926 at a distance of about 5 kpc from Earth. BVRcIc photometry of the star shows that it displays a variability of about 0.3 mag on timescales of months, with the star getting bluer when its brightness increases. Our photometric data indicate a periodicity of 151 days, which we explain as due to radial pulsations of CGCS 5926 on the basis of its global characteristics. The source is not detected at X-rays with Swift/XRT down to a 0.3-10 keV band luminosity of around 3e32 erg/s. This nondetection is apparently in contrast with the ROSAT data; however we show that, even if the probability that CGCS 5926 can be a SyXB appears quite low, the present information does not completely rule out such a possibility, while it makes other interpretations even more unlikely if we assume that the ROSAT detection was real. This issue might thus be settled by future, more sensitive, observations at high energies.

description: Hintergrund: Digitale und assistive Technologien nehmen eine prominente Rolle in der Diskussion um Lösungsansätze für die Herausforderungen der Gesundheitsversorgung ein. Für den Transfer in den Pflegealltag ist es erforderlich, Akzeptanz zu schaffen und Pflegefachpersonen in den Prozess der Digitalisierung des Gesundheitswesens zu integrieren. Allerdings wird im Rahmen der Pflegeausbildung bisher kaum Wissen für einen kompetenten Umgang mit Technologie vermittelt. Auch die zukünftige Ausbildungs- und Prüfungsordnung (Pflegeberufegesetz) unterlässt entsprechende Vorgaben. Ziel: Die Online-Umfrage soll klären, welches Maß an Aufgeschlossenheit und Fortbildungsinteresse bei Pflegeschülerinnen und Pflegeschülern zu digitalen und assistiven Technologien vorhanden ist. Methode: Eine Einladung zur Teilnahme wurde per E‑Mail an 277 Pflegeschulen in den neuen Bundesländern verschickt. Der Fragebogen wurde von der Forschergruppe entwickelt und vorab getestet. Ergebnisse: Die Nutzung von Computern können sich 94,7 % der insgesamt 415 Befragten im Klinik- oder Praxisalltag vorstellen, die Nutzung von Tablets 61,9 % und die Nutzung von Smartphones 51,1 %. Je zwei Drittel schätzen ihre Aufgeschlossenheit zu Technologie als hoch und ihr Wissen diesbezüglich als niedrig ein. Der Aussage, dass ihnen Schulungen zum bedarfsgerechten Einsatz technischer Lösungen fehlen, stimmen 71,8 % der Auszubildenden zu. Dies geht einher, mit einem hohen Fortbildungsinteresse der Auszubildenden, das je nach angebotenen Thema, von 64,8–83,4 % der Befragten geäußert wird. Schlussfolgerung: Der Bedarf und die Bereitschaft einer grundständigen Qualifizierung zu digitalen und assistiven Technologien im Rahmen der Pflegeausbildung – aber auch darüber hinaus – werden in dieser Befragung deutlich. Diese Kompetenzen müssen gezielt an einem praxisnahen Lernort („Future Care Lab“) vermittelt werden, nur so kann die digitale Transformation auf die Unterstützung qualifizierter professioneller Anwender aufbauen; andernfalls drohen langfristige Barrieren und Implementierungshindernisse.

description: We study the variation of surface differential rotation and meridional flow along the lower part of the zero age main sequence (ZAMS). We first compute a sequence of stellar models with masses from 0.3 to 1.5 solar masses. We then construct mean field models of their outer convection zones and compute differential rotation and meridional flows by solving the Reynolds equation with transport coefficients from the second order correlation approximation. For a fixed rotation period of 2.5 d we find a strong dependence of the surface differential rotation on the effective temperature with weak surface shear for M dwarfs and very large values for F stars. The increase with effective temperature is modest below 6000 K but very steep above 6000 K. The meridional flow shows a similar variation with temperature but the increase with temperature is not quite so steep. Both the surface rotation and the meridional circulation are solar-type over the entire temperature range. We also study the dependence of differential rotation and meridional flow on the rotation period for masses. from 0.3 to 1.1 solar masses. The variation of the differential rotation with period is weak except for very rapid rotation. The meridional flow shows a systematic increase of the flow speed with the rotation rate. Numerical experiments in which either the $Λ$ effect is dropped in the Reynolds stress or the baroclinic term in the equation of motion is cancelled show that for effective temperatures below 6000 K the Reynolds stress is the dominant driver of differential rotation.

description: We propose homogeneous metrics of Petrov type III that describe gyrating Schrodinger geometries as duals to some non-relativistic field theories, in which the Schrodinger symmetry is broken further so that the phase space has a linear dependence of the momentum in a selected direction. We show that such solutions can arise in four-dimensional Einstein-Weyl supergravity as well as higher-dimensional extended gravities with quadratic curvature terms coupled to a massive vector. In Einstein-Weyl supergravity, the gyrating Schrodinger solutions can be supersymmetric, preserving 1/4 of the supersymmetry. We obtain the exact Green function in the phase space associated with a bulk free massive scalar.

description: Environmental regulations are becoming more stringent in the United States and globally to reduce the climate change and human health impacts of fossil fuel use. This thesis investigates two case studies of current and future environmental regulations by developing a life cycle assessment (LCA) framework to estimate the effect on greenhouse gas (GHG) emissions of 1) an international 0.5% sulfur marine fuel limit, and 2) regional and seasonal variability in U.S. gasoline and diesel specifications. Additional modelling capability is added to the previously developed Petroleum Refining Life Cycle Inventory Model (PRELIM), which is used together with other public LCA tools including OPGEE: the Oil Production Greenhouse Gas Emissions Estimator and The Greenhouse Gases, Regulated Emissions and Energy Use in Transportation Model (GREET). For PRELIM, empirical correlations from the literature are used to expand the product slate options and user inputs that are available, and model outputs such as product specifications are added. Using hydrotreated residual marine fuel, distillate marine fuel or unhydrotreated residual marine fuel with on-board scrubbers to comply with 0.5% S marine fuel affect life cycle GHG emissions by only 2-4% from current typical operations, while using LNG engines or biodiesel blending reduce life cycle GHG emissions by 8% and 51% respectively. A life cycle cost analysis is used to compare economic viability of each option. Gasoline and diesel specifications generally contribute less to refining GHG emissions than crude quality and refinery configuration. However, variability in cetane number is the one exception which contributes largely to refining GHG emissions when comparing across the extremes of cetane standards that currently exist in the U.S. The outcome of this research provides insights into the magnitude and variability of life cycle GHG emissions as a result of downstream environmental regulations. It provides value to industry, policy makers, consumers and academics who wish to understand the economic, environmental and social trade-offs associated with these environmental regulations and their potential compliance options.

description: This study investigates the complex kinetics of thermodynamic nonequilibrium effects (TNEs) and their relative importance during the development of Kelvin-Helmholtz instability (KHI) using high-order discrete Boltzmann models (DBMs). First, the capabilities and differences among various discrete velocity sets in capturing TNEs and distribution functions are assessed. Practical guidelines for constructing discrete velocity stencils are proposed to enhance phase-space discretization and improve the robustness of high-order DBM simulation. At different stages of KHI and under varying initial conditions, multiscale TNEs, such as viscous stresses of different orders, emerge with distinct dominant roles. Specifically, three scenarios are identified: (i) regimes dominated by first-order TNEs,(ii) alternation between first- and second-order TNEs, and (iii) states where second-order TNEs govern the system's behavior. To quantitatively capture these transitions, criteria for TNE dominance at different orders in KHI evolution are established based on the relative thermodynamic nonequilibrium intensity (\(R_{\text{TNE}}\)). In scenarios dominated by second-order TNEs, differences between first-order and second-order models are compared in terms of macroscopic quantities, nonequilibrium effects, and kinetic moments, revealing the physical limitations of low-order models in capturing TNEs. Furthermore, the effectiveness, extensibility, and limitations of a representative high-order model are examined under second-order TNE-dominated conditions. To encapsulate these findings, a nonequilibrium phase diagram that visually maps the multiscale characteristics of KHI is constructed. This diagram not only provides intuitive insights into the dynamic interplay of different nonequilibrium effects but also serves as a kinetic roadmap for selecting suitable models under diverse nonequilibrium conditions.

description: The paper deals with the error analysis of a navigation algorithm that uses as input a sequence of images acquired by a moving camera and a Digital Terrain Map (DTM) of the region been imaged by the camera during the motion. The main sources of error are more or less straightforward to identify: camera resolution, structure of the observed terrain and DTM accuracy, field of view and camera trajectory. After characterizing and modeling these error sources in the framework of the CDTM algorithm, a closed form expression for their effect on the pose and motion errors of the camera can be found. The analytic expression provides a priori measurements for the accuracy in terms of the parameters mentioned above.

A content analysis of US newspaper coverage of Canada and the UK’s healthcare systems during America’s healthcare reform
Creators: name: Blackadar, Kerry Jean
Publisher: name: University of British Columbia
Year: 2010

description: This study examines how Canadian Medicare and the United Kingdom’s National Health Service (NHS) were represented in US newspaper coverage between January 2008 and the first quarter of 2010, a period marked by changing healthcare policy in America and dramatic shifts in the journalism industry at large. Through a content analysis of print news from the New York Times, Wall Street Journal, and USA Today, this paper tracked and assessed reporting dimensions and coverage themes to illustrate the quantity and quality of coverage. The analysis was based on the seminal work of Pauline M. Vaillancourt Rosenau, who performed a content analysis of newspaper coverage of Canada’s healthcare system between 2000 and mid-June 2005 in the NYT and WSJ. Findings from this thesis reveal that recent US newspaper coverage of Medicare, though narrow, is more accurate and balanced compared to coverage during Rosenau’s study timeframe. The NHS received far greater attention in US newspapers, indicating that outside factors, potentially including collaboration in the Iraq war, have spawned greater US media interest in the UK at large. On occasion, this study found coverage of the NHS to be critical, relying on anecdotal evidence to suggest systematic failure of aspects of healthcare in the UK. With respect to coverage themes, wait lines for treatment was a dominant issue in US newspaper reporting of both Canadian Medicare and the NHS. Medical tourism and problems associated with paying for universal healthcare also emerged in US representation of the NHS. This paper concludes with a discussion of outside factors that may have influenced American newspaper coverage during the study period. Considering the current state of print journalism, this paper predicts that, in the years ahead, American print coverage of foreign healthcare will continue to decline. However, in conjunction with this, it is likely that increased online representation of foreign healthcare stories will occur, as new journalism platforms, such as blogs, continue to proliferate. Finally, as American reporters continue to gain greater access to online healthcare research databases, this study suggests that the quality of US coverage of Medicare and the NHS is likely to improve.

description: Corrosion is one of the most common wear mechanisms of refractories. Corrosive attacks lead to chemical and microstructural changes. Hot corrosion compromises chemical and/or physical interactions. Thus, the process is complex and not yet fully understood. Currently, corrosion is investigated post-mortem by means of X-ray diffraction or scanning electron microscopy. These methods have the drawback that some information is lost on cooling. In-situ measurements, however, take measurements within the process. As an outcome of WP2, which is dedicated to the “Advanced characterisation of raw materials, refractories and joints”, this report will review the mechanical characterization of corroded samples (specific output of Task 2.5). The relationship between the corroded microstructure and thermomechanical behaviour of refractory linings will be analysed. With the in-situ and ex-situ measurements two different approaches have been chosen. Both studies have been performed individually with specifically produced materials. The steel ladle, a metallurgical vessel which is the common thread for all the research carried out within the ATHOR project, is widely used in secondary metallurgy. One of the key issues faced by the steel ladle during its lifetime, is corrosion. In this report in-situ and ex-situ approaches have been used to investigate the effects of corrosion on laboratory prepared and industrially supplied, refractory castables. In-situ measurements have been used, at room and elevated temperatures, to investigate the impact of different, synthesised, slag compositions on several, laboratory prepared, alumina-based refractory materials. These in-situ investigations (along with a novel testing of coupled thermal shock with corrosion) are detailed in Section 2 of this document. Section 3 describes the development of an ex-situ testing procedure for the Brazilian test after corrosion of the sample as well as some initial results. Some analysis of refractory materials used in the industrial lining of the steel ladle is also described.

Oh Canada: Citizenship on First Nations’ Land

subject: Educational Technology

description: There is extensive scholarly research on the teaching and integration of citizenship education within formal learning environments (Knight Abowitz & Harnish, 2006; McLaughlin, 2006). Within Ontario it is an integral component of the social studies program developed by the province (Ministry of Education, 2004b), with a distinct focus on what it means to be Canadian (Brodie, 2002) within the grade 5 curriculum (Ministry of Education, 2004b). While these topics have been studied there has been limited work completed on the teaching of citizenship, especially Canadian citizenship, to First Nations students. With some researchers stating that First Nations should not be in a state of subjection to the Canadian government (Battiste & Semaganis, 2002), there are First Nation members who argue that they are First Nation and do not want to be recognized as Canadian. Therefore, the goal of this phenomenological study was twofold. The first goal was to examine how a teacher, working within a school in a First Nation community planned, delivered and assessed the Ontario grade 5 social studies curriculum titled “Aspects of Citizenship and Government in Canada” (Ministry of Education, 2004b, pg. 8). The second objective was to understand how the students and community members, including the teacher and Elders understood the concept of citizenship. After I was able to respectfully obtain assent for completing the research within a community in southwestern Ontario, data collection took place through interviews of grade five students, the teacher and the elder who was a guest speaker in the class. Field notes were also collected by watching the delivery of the unit in the class by the teacher. The results of this study demonstrated the complexity of delivering this unit in a school located within a First Nation community, as the teacher had to balance the expectations of the curriculum along with the expectations of the community. The study also provided an opportunity to start understanding the multiple ways citizenship is understood by different members of the community.

Loy and Willis observed that the set of operators whose final column is continuous when viewed as a scalar-valued function on $[0,ω_1]$ defines a maximal ideal of codimension one in the Banach algebra $\mathscr{B}(C([0,ω_1]))$ of bounded operators on $C([0,ω_1])$. We give a coordinate-free characterization of this ideal and deduce from it that $\mathscr{B}(C([0,ω_1]))$ contains no other maximal ideals. We then obtain a list of equivalent conditions describing the strictly smaller ideal of operators with separable range, and finally we investigate the structure of the lattice of all closed ideals of $\mathscr{B}(C([0,ω_1]))$.

description: A Limit Order Book (LOB) is a financial exchange that automatically matches the orders of buyers and sellers according to a predefined priority rule. As the popularity of Limit Order markets has increased, more attention has been paid to the optimal strategies for an agent who wishes to buy or sell an equity on the order book. In this thesis, we first introduce challenges of market microstructure and concepts of stochastic optimal control such as the Dynamic Programming Principle, the Hamilton-Jacobi-Bellman Equation, and tools such as the Feynman-Kac Formula. Then, we present Fodra and Pham's model for the optimal risk-neutral market making strategy in a limit order book that follows a Semi-Markov stochastic process, and use numerical techniques in MATLAB to apply the theory to real-word Limit Order data. Statistical techniques such as Maximum Likelihood Estimation, the Kolmogorov-Smirnov Test and Akaike Information Criterion are employed to distributions such as the Generalized Inverse Gaussian. Finally, we find the optimal risk-neutral strategy in an extension of the model when the price process contains a stochastic bid-ask spread following a Markov Chain.

description: We consider a supercritical branching population, where individuals have i.i.d. lifetime durations (which are not necessarily exponentially distributed) and give birth (singly) at constant rate. We assume that individuals independently experience neutral mutations, at constant rate $θ$ during their lifetimes, under the infinite-alleles assumption: each mutation instantaneously confers a brand new type, called allele or haplotype, to its carrier. The type carried by a mother at the time when she gives birth is transmitted to the newborn. We are interested in the sizes and ages at time $t$ of the clonal families carrying the most abundant alleles or the oldest ones, as $t\to\infty$, on the survival event. Intuitively, the results must depend on how the mutation rate $θ$ and the Malthusian parameter $α>0$ compare. Hereafter, $N\equiv N_t$ is the population size at time $t$, constants $a,c$ are scaling constants, whereas $k,k'$ are explicit positive constants which depend on the parameters of the model. When $α>θ$, the most abundant families are also the oldest ones, they have size $cN^{1-θ/α}$ and age $t-a$. When $α

description: Summary This experiment focuses on the application of AutoMH, a framework for the automatic generation of evolutionary algorithms, to address the problem of calculating the Star Discrepancy 𝐿∞ of a given set of points. The AutoMH with the use of reinforcement learning has searched in the episodes for an algorithm that satisfactorily solves problems 39, 49, and 59 of the data set provided by the IOHprofiler environment [1]. Once the episodes are finished, the algorithm that has had the best performance is extracted, this algorithm will be called AutoMH-SD. The AutoMH-SD algorithm will be the one that solves 30 different Star Discrepancy problems using the IOHprofiler environment in instances from 2 to 20 dimensions [2]. The AutoMH-SD algorithm will focus on solving the problems of numerical black box optimization approaches operating on [0,1), with low budget of 500 and high budget of 2500. 1. https://iohprofiler.github.io IOHprofiler. 2. https://iohprofiler.github.io/competitions/stardiscr GECCO 2023 Competition on Star Discrepancy Computation.

The impact of narratives on policy-making at the national level. The case of the United Kingdom

description: This report analyses how different narratives on migration shape and are deployed in political debate and policymaking in the United Kingdom. It investigates how political actors process salient narratives on migration that emerge in the public and political domain and how they inform policy. Of particular interest is the question of how often simplistic, emotive narratives on migration circulating in sections of the British media and political debate are processed in policy-making spheres. Focusing on three case studies, the 2015 'migration crisis', the Ukrainian refugee crisis in 2022 and 'small boat' arrivals in 2022, the report aims to elucidate how migration narratives 'move' across mass media coverage, political debate, and policymaking. The first section sets out long-standing narratives on migration in the UK, key political and policy developments over the past decade and the salience of immigration and public opinion. Deploying a unique methodology to trace government strategies for responding to narratives, the second section analyses the dominant narratives in the British press, parliamentary debate, and policy documentation in each of the three cases. In the third and final section, the report concludes that there is considerable alignment in narratives across the media, political debate, and policy documents. Despite variations in narrative style, policy-making venues appear to embrace more 'lay' and populist narratives invoked in political debate. Moreover, narratives are often embedded in long-standing 'master' narratives on migration in the United Kingdom.

On Improved Loss Estimation for Shrinkage Estimators

description: Let $X$ be a random vector with distribution $P_θ$ where $θ$ is an unknown parameter. When estimating $θ$ by some estimator $φ(X)$ under a loss function $L(θ,φ)$, classical decision theory advocates that such a decision rule should be used if it has suitable properties with respect to the frequentist risk $R(θ,φ)$. However, after having observed $X=x$, instances arise in practice in which $φ$ is to be accompanied by an assessment of its loss, $L(θ,φ(x))$, which is unobservable since $θ$ is unknown. A common approach to this assessment is to consider estimation of $L(θ,φ(x))$ by an estimator $δ$, called a loss estimator. We present an expository development of loss estimation with substantial emphasis on the setting where the distributional context is normal and its extension to the case where the underlying distribution is spherically symmetric. Our overview covers improved loss estimators for least squares but primarily focuses on shrinkage estimators. Bayes estimation is also considered and comparisons are made with unbiased estimation.

Tevatron Top $A_{FB}$ Versus LHC Top Physics

description: We carry out a comprehensive analysis of models for top A_{FB} at CDF in light of new top data arriving from the LHC. We begin with a careful Tevatron analysis, considering in general which sets of effective vertices give rise to a large forward-backward asymmetry while suppressing the contribution to the total t tbar cross-section. We show on general grounds that scalar models struggle to produce sufficient asymmetries consistent with CDF observations, while vector models can produce a large asymmetry with a less significant tension in the total cross-section and $t\bar{t}$ invariant mass distribution at the Tevatron. We examine the essential observables of these models for top physics at LHC7 with 1 fb^{-1} of data, including the total cross-section, invariant mass distribution and number of additional jets in t tbar events. In the case of t-channel mediators, the LHC total cross-section places a strong constraint on light mediators, while the Tevatron invariant mass distributions place strong constraints on heavy mediators that are able to produce the asymmetry. Heavy axigluons are becoming increasingly squeezed by LHC7 t tbar and dijet resonance searches. We conclude that LHC7 top analyses are rapidly closing the window for viable models of the CDF top A_{FB}.
