description: We use linear response theory in order to compute the light absorption spectrum, in the terahertz band, of a polariton system composed by excitons in a quantum dot very strongly coupled to the lowest photon mode of a thin micropillar. In a thermalized (Bose condensed) system at low temperatures, the spectral function shows a peak (GDR) associated to a 1s - 2p exciton transition, enhanced by polariton effects. On the other hand, in a non-equilibrium system absorption is peaked at low energies. Thus, a measurement of terahertz absorption could give an indication of the degree of thermalization in the polariton system.

description: Background In environmental health research, sex and gender are not yet adequately considered. There is a need to improve data collection in population-based environmental health studies by comprehensively surveying sex/gender-related aspects according to gender theoretical concepts. Thus, within the joint project INGER we developed a multidimensional sex/gender concept which we aimed to operationalize and to test the operationalization for feasibility. Methods In an iterative process, we created questionnaire modules which quantitatively captured the requirements of the INGER sex/gender concept. We deployed it in the KORA cohort (Cooperative Health Research in the Region of Augsburg, Germany) in 2019 and evaluated response and missing rates. Results The individual sex/gender self-concept was surveyed via a two-step approach that asked for sex assigned at birth and the current sex/gender identity. Additionally, we used existing tools to query internalized sex/gender roles and externalized sex/gender expressions. Adapted to the KORA population, we asked for discrimination experiences and care and household activities contributing to explain structural sex/gender relations. Further intersectionality-related social categories (e.g., socio-economic position), lifestyle and psychosocial factors were covered through data available in KORA. We could not identify appropriate tools to assess the true biological sex, sexual orientation and ethnic/cultural identity, which have yet to be developed or improved. The response-rate was 71%, the evaluation of 3,743 questionnaires showed a low missing rate. Prevalence of marginalized groups regarding sex/gender identity and definable by experiences of discrimination was very low. Conclusion We have shown how the multidimensional INGER sex/gender concept can be operationalized according to an European and North American understanding of sex/gender for use in quantitative research. The questionnaire modules proved feasible in an epidemiologic cohort study. Being a balancing act between theoretical concepts and its quantitative implementation our operationalization paves the way for an adequate consideration of sex/gender in environmental health research.

description: In the late 1990s, observations of type Ia supernovae led to the astounding discovery that the universe is expanding at an accelerating rate. The explanation of this anomalous acceleration has been one of the great problems in physics since that discovery. We propose cosmological models that can simply and elegantly explain the cosmic acceleration via the geometric structure of the spacetime continuum, without introducing a cosmological constant into the standard Einstein field equation, negating the necessity for the existence of dark energy. In this geometry, the three fundamental physical dimensions length, time, and mass are related in new kind of relativity. There are four conspicuous features of these models: 1) the speed of light and the gravitational constant are not constant, but vary with the evolution of the universe, 2) time has no beginning and no end; i.e., there is neither a big bang nor a big crunch singularity, 3) the spatial section of the universe is a 3-sphere, and 4) in the process of evolution, the universe experiences phases of both acceleration and deceleration. One of these models is selected and tested against current cosmological observations, and is found to fit the redshift- luminosity distance data quite well.

Finite Projective Spaces, Geometric Spreads of Lines and Multi-Qubits

description: Given a (2N - 1)-dimensional projective space over GF(2), PG(2N - 1, 2), and its geometric spread of lines, there exists a remarkable mapping of this space onto PG(N - 1, 4) where the lines of the spread correspond to the points and subspaces spanned by pairs of lines to the lines of PG(N - 1, 4). Under such mapping, a non-degenerate quadric surface of the former space has for its image a non-singular Hermitian variety in the latter space, this quadric being {\it hyperbolic} or {\it elliptic} in dependence on N being {\it even} or {\it odd}, respectively. We employ this property to show that generalized Pauli groups of N-qubits also form two distinct families according to the parity of N and to put the role of symmetric operators into a new perspective. The N=4 case is taken to illustrate the issue.

description: Abstract: Background: In the phase 2 CAMMS223 trial (NCT00050778), alemtuzumab significantly improved clinical and MRI outcomes versus subcutaneous interferon beta-1a over 3 years in treatment-naive patients with relapsing–remitting MS. Here, we assess efficacy and safety of alemtuzumab over 12 years in CAMMS223 patients who enrolled in the CAMMS03409 extension (NCT00930553), with available follow-up through the subsequent TOPAZ extension (NCT02255656). Methods: In CAMMS223, patients received 2 alemtuzumab courses (12 mg/day; baseline: 5 days; 12 months later: 3 days); 22% received a third course. In the open-label, nonrandomized extensions, patients could receive as-needed additional alemtuzumab or other disease-modifying therapies. Results: Of 108 alemtuzumab-treated patients in CAMMS223, 60 entered the CAMMS03409 extension; 33% received a total of 2 alemtuzumab courses, and 73% received no more than 3 courses through Year 12. Over 12 years, annualized relapse rate was 0.09, 71% of patients had stable or improved Expanded Disability Status Scale scores, and 69% were free of 6-month confirmed disability worsening. In Year 12, 73% of patients were free of MRI disease activity. Cumulatively throughout the extensions (Years 7–12), 34% of patients had no evidence of disease activity. Adverse event (AE) incidence declined through Year 12. Infusion-associated reactions peaked at first course and declined thereafter. Cumulative thyroid AE incidence was 50%; one immune thrombocytopenia event occurred, and there were no autoimmune nephropathy cases. Conclusions: Alemtuzumab efficacy was maintained over 12 years in CAMMS223 patients, with 73% receiving no more than three courses. The safety profile in this cohort was consistent with other alemtuzumab clinical trials.

description: The maximally random jammed (MRJ) state is the most random configuration of strictly jammed (mechanically rigid) nonoverlapping objects. MRJ packings are hyperuniform, meaning their long-wavelength density fluctuations are anomalously suppressed compared to typical disordered systems, i.e., their structure factors $S(\mathbf{k})$ tend to zero as the wavenumber $|\mathbf{k}|$ tends to zero. Here, we show that generating high-quality strictly jammed states for space dimensions $d = 3,4,$ and $5$ is of paramount importance in ensuring hyperuniformity and extracting precise values of the hyperuniformity exponent $α> 0$ for MRJ states, defined by the power-law behavior of $S(\mathbf{k})\sim|\mathbf{k}|^α$ in the limit $|\mathbf{k}|\rightarrow0$. Moreover, we show that for fixed $d$ it is more difficult to ensure jamming as the particle number $N$ increases, which results in packings that are nonhyperuniform. Free-volume theory arguments suggest that the ideal MRJ state does not contain rattlers, which act as defects in numerically generated packings. As $d$ increases, we find that the fraction of rattlers decreases substantially. Our analysis of the largest truly jammed packings suggests that the ideal MRJ packings for all dimensions $d\geq3$ are hyperuniform with $α= d - 2$, implying the packings become more hyperuniform as $d$ increases. The differences in $α$ between MRJ packings and recently proposed Manna-class random close packed (RCP) states, which were reported to have $α= 0.25$ in $d=3$ and be nonhyperuniform ($α= 0$) for $d = 4$ and $d = 5$, demonstrate the vivid distinctions between the large-scale structure of RCP and MRJ states in these dimensions. Our work clarifies the importance of the link between true jamming and hyperuniformity and motivates the development of an algorithm to produce rattler-free three-dimensional MRJ packings.

description: Three-particle correlations in quark and gluon jets are computed for the first time in perturbative QCD. We give results in the double logarithmic approximation and the modified leading logarithmic approximation. In both resummation schemes, we use the formalism of the generating functional and solve the evolution equations analytically from the steepest descent evaluation of the one-particle distribution. We thus provide a further test of the local parton hadron duality and make predictions for the LHC.

description: This study aimed to assess and analyze the existing condition of inventory deadstock at Aegis Medical Company, Bahrain's first and only licensed face mask production plant, and devised recommendations aimed at reducing the deadstock level. This study employed Lean Inventory thinking techniques; qualitative and quantitative data collection methods, including observations and inventory data gathering, were employed to comprehensively understand the deadstock issue.Root cause analysis was central to the investigation, utilizing tools such as the Fish-Bone Diagram and Pugh Matrix. These tools were instrumental in identifying critical factors contributing to the high deadstock levels. Findings revealed that one major contributor was the lack of a focused sales strategy, leading to the disconnection of the team from the company mission and products, ultimately bringing in fewer leads and a decrease in sales over time.After a comprehensive analysis, the outcomes were summarized as follows: it was recommended to implement a targeted sales strategy, explore co-manufacturing or white labeling of the existing mask inventory; and the donation of the masks currently held in inventory. By implementing these recommendations, the study anticipated a reduction in deadstock levels.
Reconstructing experience in ancient Rome and Chang'an : a comparative approach
Creators: name: Liu, Yanxing
Publisher: name: University of British Columbia
Year: 2022

description: Using comparative approach, this present thesis explores the potential of comparison in the study of ancient capital cities and their residents’ living experience. Although Rome and Chang’an have received a great deal of attention respectively, little work has been done to compare these two capital cities. This neglect is intriguing given the fact that scholars were enthusiastic about comparing the Roman Empire and the Han Empire, two powerful regimes siting on the opposite ends of Eurasia. While most scholarship has been focusing on comparing the rise and fall of empires, the military systems, and the management of territories, the thesis analyzes the capital cities and their differences. Another similar problem that this thesis tries to tackle is the neglect of marginalized people’s living experience in great cities. Non-elite people made up most of the urban population, but the scarcity of evidence prevents us from understanding their daily life. Therefore, the thesis applies Henri Lefebvre’s theory of spatial triad to access the non-elite people’s living experience in two selected places: the Porta Esquilina in Rome and the Xuanping Gate in Chang’an. City gates could offer best available material evidence for the purpose of this thesis. The research carried out in the thesis reveals that non-elite people’s living experience in these two distinct cities might be surprisingly similar.

description: Abstract: Uterine leiomyomata (UL) are the most common neoplasms of the female reproductive tract and primary cause for hysterectomy, leading to considerable morbidity and high economic burden. Here we conduct a GWAS meta-analysis in 35,474 cases and 267,505 female controls of European ancestry, identifying eight novel genome-wide significant (P < 5 × 10−8) loci, in addition to confirming 21 previously reported loci, including multiple independent signals at 10 loci. Phenotypic stratification of UL by heavy menstrual bleeding in 3409 cases and 199,171 female controls reveals genome-wide significant associations at three of the 29 UL loci: 5p15.33 (TERT), 5q35.2 (FGFR4) and 11q22.3 (ATM). Four loci identified in the meta-analysis are also associated with endometriosis risk; an epidemiological meta-analysis across 402,868 women suggests at least a doubling of risk for UL diagnosis among those with a history of endometriosis. These findings increase our understanding of genetic contribution and biology underlying UL development, and suggest overlapping genetic origins with endometriosis.

description: We perform a detailed study of the renormalization group equations in the inverse seesaw model. Especially, we derive compact analytical formulas for the running of the neutrino parameters in the standard model and the minimal supersymmetric standard model, and illustrate that, due to large Yukawa coupling corrections, significant running effects on the leptonic mixing angles can be naturally obtained in the proximity of the electroweak scale, perhaps even within the reach of the LHC. In general, if the mass spectrum of the light neutrinos is nearly degenerate, the running effects are enhanced to experimentally accessible levels, well suitable for the investigation of the underlying dynamics behind the neutrino mass generation and the lepton flavor structure. In addition, the effects of the seesaw thresholds are discussed, and a brief comparison to other seesaw models is carried out.

description: Jupiter's atmosphere-interior is a coupled fluid dynamical system strongly influenced by the rapid background rotation. While the visible atmosphere features east-west zonal winds on the order of 100 m/s (Tollefson et al. 2017), zonal flows in the dynamo region are significantly slower, on the order of 1 cm/s or less, according to the latest magnetic secular variation analysis (Bloxham et al. 2022). The vertical profile of the zonal flows and the underlying mechanism remain elusive. The latest Juno radio tracking measurements afforded the derivation of Jupiter's gravity field to spherical harmonic degree 40. Here, we use the latest gravity solution to reconstruct Jupiter's deep zonal winds without a priori assumptions about their latitudinal profile. The pattern of our reconstructed deep zonal winds strongly resembles that of the surface wind within $\pm$ 35 degrees latitude from the equator, in particular the northern off-equatorial jet (NOEJ) and the southern off-equatorial jet (SOEJ) (Kulowski et al. 2021). The reconstruction features larger uncertainties in the southern hemisphere due to the north south asymmetric nature of Juno's trajectory. Amplitude of the reconstructed deep NOEJ matches that of the surface wind when the wind is truncated at a depth around 2500 km, and becomes twice that of the surface wind if the truncation depth is reduced to about 1500 km. Our analysis supports the physical picture in which prominent part of the surface zonal winds extends into Jupiter's interior significantly deeper than the water cloud layer.

description: $TeO_2$ crystals are used as bolometers in experiments searching for Double Beta Decay without emission of neutrinos. One of the most important issues in this extremely delicate kind of experiments is the characterization of the background. The knowledge of the response to $α$ particles in the energy range where the signal is expected is therefore a must. In this paper we report the results on the response function of a $TeO_2$ bolometer to $α$'s emitted by $^{147}$Sm dissolved in the crystal at the growth phase. A Quenching Factor of ($1.0076\pm 0.0005$) is found, independent of the temperature in the investigated range. The energy resolution on $α$ peaks shows a standard calorimeter energy dependence: $σ\; [\rm{keV}] = (0.56 \pm 0.02) \oplus (0.010 \pm 0.002)\sqrt{E[\rm{keV}]} $. Signal pulses show no difference between $α$ and $βγ$ particles

description: Marine lakes are bodies of seawater that are land-locked and maintain a subterranean connection to the surrounding sea. Here, we document the species diversity of benthic molluscs in 11 marine lakes in Raja Ampat, West Papua, Indonesia, using the roving diving survey method. We specifically tested for relationships between species richness and lake size and the degree of connection to the surrounding sea, and tested potential environmental drivers of community structure. We recorded 73 species, belonging to the classes Gastropoda (48 species, comprising 36 genera and 25 families), Bivalvia (24 species, consisting of 17 genera and 12 families), and Polyplacophora (one species). Molluscs from marine lakes are a subset of species also occurring in coral, seagrass, mangrove, and rocky shore habitats in the open sea. We found lake communities to mostly consist of grazers and filter feeders. The number of mollusc species significantly increased with increasing connection to the surrounding sea, but not with increasing surface area, indicating that dispersal potential may be the main driving force. Furthermore, we observed no significant influence of the environment on the variation in mollusc species composition among marine lakes. Still, we observed certain species to be exclusively present in either high or low-connected lakes, indicating a potential effect of environmental filtering. Marine lakes provide a unique ecosystem for diverse mollusc assemblages and as such should be protected.

description: We study the expansion of single-particle and two-particle imaginary-time Matsubara Green's functions of quantum impurity models in the basis of Legendre orthogonal polynomials. We discuss various applications within the dynamical mean-field theory (DMFT) framework. The method provides a more compact representation of the Green's functions than standard Matsubara frequencies and therefore significantly reduces the memory-storage size of these quantities. Moreover, it can be used as an efficient noise filter for various physical quantities within the continuous-time quantum Monte Carlo impurity solvers recently developed for DMFT and its extensions. In particular, we show how to use it for the computation of energies in the context of realistic DMFT calculations in combination with the local density approximation to the density functional theory (LDA+DMFT) and for the calculation of lattice susceptibilities from the local irreducible vertex function.

description: We present a novel way of realizing the pseudo-Nambu-Goldstone boson mechanism at all orders in perturbation theory, for the doublet-triplet splitting in supersymmetric grand unified theories. The global symmetries of the Higgs sector are attributed to a non-vectorlike Higgs content, which is consistent with unbroken supersymmetry in a scenario with flat extra dimensions and branes. We also show how in such a model one can naturally obtain a realistic pattern for the Standard Model fermion masses and mixings.

description: We study the asymptotic behavior of empirical processes generated by measurable bounded functions of an infinite source Poisson transmission process when the session length have infinite variance. In spite of the boundedness of the function, the normalized fluctuations of such an empirical process converge to a non-Gaussian stable process. This phenomenon can be viewed as caused by the long-range dependence in the transmission process. Completing previous results on the empirical mean of similar types of processes, our results on non-linear bounded functions exhibit the influence of the limit transmission rate distribution at high session lengths on the asymptotic behavior of the empirical process. As an illustration, we apply the main result to estimation of the distribution function of the steady state value of the transmission process.

This is realized by open strings ending on the D3 brane known as the Y=0 maximal giant graviton in AdS_5 x S^5. We also consider the Yangian symmetry of the boundary which preserves an su(1|2) subalgebra only.

description: Local distortions of the crystal structure and their influence on the electronic structure, electron-phonon interaction, and superconductivity are theoretically studied in the superconducting high-entropy alloy (HEA) (TaNb)$_{0.67}$(HfZrTi)$_{0.33}$. Distortions of the crystal lattice are caused by the relaxation of atomic positions and are studied in the twelve models of supercells. The largest relative changes in the interatomic distances due to relaxation reach 8\%. On average, local distortions tend to lower the density of states at the Fermi level and significantly reduce the electron-phonon coupling parameter $λ$. As a result, the calculated superconducting critical temperature is reduced to about 50\% of the initial value, which shows the strong impact of structural disorder on superconductivity in this prototype high-entropy alloy. With the reduced value of $λ$, the theoretical $T_c$ is closer to the experiment for typical values of the Columomb pseudopotential parameter $μ^*$. The experimental $T_c$ can be reproduced by taking a slightly enhanced $μ^* = 0.176$, which leaves little room for the possibility of suppression of superconductivity by disorder.

description: There has been a substantial amount of research on the relationship between hippocampal neurogenesis and behaviour over the past fifteen years, but the causal role that new neurons have on cognitive and affective behavioural tasks is still far from clear. This is partly due to the difficulty of manipulating levels of neurogenesis without inducing off-target effects, which might also influence behaviour. In addition, the analytical methods typically used do not directly test whether neurogenesis mediates the effect of an intervention on behaviour. Previous studies may have incorrectly attributed changes in behavioural performance to neurogenesis because the role of known (or unknown) neurogenesis-independent mechanisms were not formally taken into consideration during the analysis. Causal models can tease apart complex causal relationships and were used to demonstrate that the effect of exercise on pattern separation is via neurogenesis-independent mechanisms. Many studies in the neurogenesis literature would benefit from the use of statistical methods that can separate neurogenesis-dependent from neurogenesis-independent effects on behaviour.

description: We study an inflationary scenario in supergravity model with a gauge kinetic function. We find exact anisotropic power-law inflationary solutions when both the potential function for an inflaton and the gauge kinetic function are exponential type. The dynamical system analysis tells us that the anisotropic power-law inflation is an attractor for a large parameter region.

description: Technical Debt (TD) refers to non-optimal decisions made in software projects that may lead to short-term benefits, but potentially harm the system's maintenance in the long-term. Technical debt management (TDM) refers to a set of activities that are performed to handle TD, e.g., identification. These activities can entail tasks such as code and architectural analysis, which can be time-consuming if done manually. Thus, substantial research work has focused on automating TDM tasks (e.g., automatic identification of code smells). However, there is a lack of studies that summarize current approaches in TDM automation. This can hinder practitioners in selecting optimal automation strategies to efficiently manage TD. It can also prevent researchers from understanding the research landscape and addressing the research problems that matter the most. Thus, the main objective of this study is to provide an overview of the state of the art in TDM automation, analyzing the available tools, their use, and the challenges in automating TDM. For this, we conducted a systematic mapping study (SMS), and from an initial set of 1086 primary studies, 178 were selected to answer three research questions covering different facets of TDM automation. We found 121 automation artifacts, which were classified in 4 different types (i.e., tools, plugins, scripts, and bots); the inputs/outputs and interfaces were also collected and reported. Finally, a conceptual model is proposed that synthesizes the results and allows to discuss the current state of TDM automation and related challenges. The results show that the research community has investigated to a large extent how to perform various TDM activities automatically, considering the number of studies and automation artifacts we identified. More research is needed towards fully automated TDM, specially concerning the integration of the automation artifacts.

description: The olive ridley sea turtle (Lepidochelys olivacea) experienced a global population decline of about 30% over two generations. Threats include direct take of turtle eggs for human consumption and indirect take of adults via incidental catch in fishing gear, known as bycatch. Chacocente beach in Nicaragua is one of ten mass nesting sites for olive ridleys in the world. The shore of Chacocente is under military protection and the surrounding waters are part of an established marine protected area (MPA). In the neighboring community of El Astillero, 60% of households are economically dependent on fishing. Fishers expressed concern for turtle bycatch in gillnets and managers expressed concern for uncontrolled fishing; however, bycatch in this region has not been quantified. This study examines bycatch in reference to the protected area’s design logics to understand whether management strategies have encouraged the desired fisher behavior and outcomes as concerns olive ridleys. Through document analysis, we derived four unintentional assumptions that seem to inform management design. We then compared these unintentional assumptions to 586 net set observations conducted in 2019. Results showed 24 turtles were caught inside the MPA, 24 turtles caught outside the MPA, with 0.04 and 0.03 turtles caught per 100 meters of net, respectively. While bycatch is similar inside and outside the MPA, revealing a lack of compliance with MPA boundaries, bycatch varied greatly between targeted species and month, with relatively high proportions of bycatch occurring in the snook fishery and in September. Such variance is not accounted for in regulations. To build quality protection in practice – not quantity of parks on paper – we aim to improve understanding of fishing interactions at-sea and make recommendations for management design that work for both sea turtle populations and fisher livelihood security.

description: We report the first observation of the radiative decay B^0 -> ϕK^0 γusing a data sample of 772 x 10^6 B B-bar pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^+e^- collider. We observe a signal of 37+/-8 events with a significance of 5.4 standard deviations including systematic uncertainties. The measured branching fraction is ${\cal B}(B^0 -> ϕK^0 γ) = (2.74\pm 0.60 \pm 0.32) \times 10^{-6}$, where the uncertainties are statistical and systematic, respectively. We also report the first measurements of time-dependent CP violation parameters: ${\mathcal S}_{ϕK_S^0 γ} = +0.74^{+0.72}_{-1.05} (stat)^{+0.10}_{-0.24} (syst)$ and ${\mathcal A}_{ϕK_S^0 γ} = +0.35 +/- 0.58 (stat)^{+0.23}_{-0.10} (syst)$. Furthermore, we measure ${\mathcal B}(B^+ -> ϕK^+ γ) = (2.48 +/- 0.30 +/- 0.24) x 10^{-6}$, ${\mathcal A}_{CP} = -0.03 +/- 0.11 +/- 0.08$ and find that the signal is concentrated in the M_{ϕK} mass region near threshold.

The impact of cash transfers across the economic spectrum

description: Cash transfers are an effective tool to alleviate poverty in lower income countries. By enabling people to flexibly meet their needs, cash transfers improve health, psychological well-being, education, and employment outcomes. Despite these documented benefits for people living in poverty, there is a dearth of research across diverse socioeconomic circumstances. In this dissertation, I examine how cash transfers influence people’s well-being across the global economic spectrum (i.e., people who are homeless, and people with low, middle, and high incomes). In Study 1, I use a cluster-randomized controlled trial to test the impact of an unconditional cash transfer of CAD$7,500 to each of 50 individuals experiencing homelessness, with another 65 as controls in Vancouver, BC. Over one year, cash recipients spent fewer days homeless, increased savings and spending with no increase in temptation goods spending, and generated societal net savings of $777 per recipient via reduced time in shelters. In Study 2, I document a potential barrier to implementing cash transfer policies for people experiencing homelessness: there is public mistrust toward the ability of homeless individuals to manage money. In Study 3, I test interventions to overcome this mistrust and increase public support for such a policy using messaging that highlights the benefits of cash transfers. These studies provide the first empirical evidence demonstrating the potential for cash transfers as a tool to address homelessness; but, do the benefits of cash transfers extend beyond those living in poverty? In Studies 4-5, I analyzed data from another randomized controlled trial to examine the impact of cash transfers with a diverse sample spanning the global economic spectrum. Two-hundred people from seven countries received cash gifts of $10,000 each, with another 100 as controls. In Study 4a, I show that cash recipients at most income levels experienced gains in well-being, but the gains were largest for lower-income recipients. In Study 4b, I find that cash recipients spent significant portions of the money generously on others, illustrating how benefits can spread through social networks. Overall, this research demonstrates that cash transfers are a flexible tool that can provide benefits across the economic spectrum.

description: We present a new high precision measurement of parity violation in the weak interaction, using polarized muon decay. The TWIST collaboration has measured $P_μ^πξ$, where $P_μ^π$ is the polarization of the muon in pion decay and $ξ$ describes the intrinsic asymmetry in muon decay. We find $P_μ^πξ= 1.00084 \pm 0.00029\,(\textrm{stat.})_{-0.00063}^{+0.00165}\,(\textrm{syst.})$, in good agreement with the standard model prediction of $P_μ^π=ξ=1$. Our result is a factor of 7 more precise than the pre-TWIST value, setting new limits in left-right symmetric electroweak extensions to the standard model.

title: The impact of variation in critical care organisation on patient mortality: evidence form the United Kingdom
Creators: name: Maharaj, Ritesh

description: The changing landscape of aging population, increasing incidence of critical illness and more constrained national budgets mean physicians, policy makes, and hospital administrators must consider more efficient ways to organise critical care services. In general, policymakers have embraced the idea of centralising services and increased specialisation to improve efficiency in health care. This thesis explores these policies in the context of critical care services in the UK. Evidence of the productivity of critical care services and in particular volume-outcome relationship in critical care and the underlying mechanism by which this relationship operates is scarce. I consider several aspects of these issues. In the first study I investigate the volume-outcome relationship for sepsis using data from the Intensive Care National Audit and Research Centre which covers all ICUs in the England, Wales, and Northern Ireland. In this cohort study, sepsis case volume in an ICU was significantly associated with hospital mortality from sepsis, and a volume lower threshold of 215 patients per year was associated with an improvement in mortality. The second study explores the underlying mechanism of the volume-outcome relationship. Two possible mechanisms proposed are dynamic learning-by-doing and static scale economies. If the volume-outcome relationship operates through the learning-by-doing mechanism, then patient outcomes would improve by the volume of patients treated over time, making system-wide centralisation unnecessary. This study supports the idea that the underlying mechanism by which volume leads to improved outcomes is through learning-by-doing. ICUs tend to improve by caring for a large volume patients distributed over time. Patients may, therefore, be better served by ICUs organised to achieve minimum volume 5 standards without centralisation. The third study examines the related role of ICU specialisation in improving mortality. This study found that ICU specialisation do not have significantly lower hospital mortality for critically ill patients in the UK after adjusting for patient characteristics and caseload volume. Across the three studies I argue that a minimum volume threshold may be effective in improving patient outcomes. Centralisation may not fully leverage the benefits of the learning-by-doing mechanism. Lastly, accounting for volume, there is no compelling evidence of any added value from ICUs specialisation.
