description: What matters primarily in the control of airborne sound transmission is the total mass per unit area of the subfloor and ceiling layers. Anything that increases the total mass -- other than the mass of the joists -- increases the sound isolation. That is valid for both joist floors and concrete slab floors. What matters secondarily is that the gypsum board ceiling is held by resilient channels to the joists. (If the gypsum board ceiling is rigidly attached, the STC has little chance of rising to 50.) Several other variables, either with the materials or the way in which they are used, can influence the sound isolation somewhat.
description: La première variable qui permet de réduire la transmission des sons aériens est la masse totale par unité de surface du support de revêtement de sol et des épaisseurs de sous-face. Tout ce qui augmente la masse totale - à part la masse des solives - augmente l'isolement acoustique. Ceci s'applique aux planchers avec solives mais aussi aux planchers avec dalle de béton. Un autre facteur qui influe sur l'ITS est l'utilisation de profilés souples pour fixer les plaques de plâtre aux solives. (Si la plaque de plâtre est fixée directement, l'ITS a peu de chances d'atteindre une valeur de 50.) Enfin plusieurs autres variables, soit dans les matériaux, soit dans la façon dont ils sont utilisés, peuvent avoir une incidence, d'une manière ou d'une autre, sur l'isolement acoustique.

description: The placement of electrical outlet boxes made from metal in partition walls that separate units in a multi-family dwelling, can raise concerns regarding sound isolation. Outlet boxes made from plastic have no effect on sound isolation, no matter where in the wall they are placed relative to one another. With metallic electrical outlets, it does matter. In fact, the placement can make a difference of up to 6 STC points. Besides their strategic placement in a wall, it is also possible to treat these outlet boxes with sound-absorbing materials. This can help somewhat. Electrical outlet boxes decrease the fire resistance of partition walls.
description: L'emplacement des boîtiers électriques métalliques dans les cloisons qui séparent les logements des habitations multifamiliales peut avoir des répercussions sur l'isolement acoustique. Les boîtiers en plastique n'ont quant à eux aucune incidence sur l'isolement acoustique, quelle que soit leur position l'un par rapport à l'autre. En revanche, lorsqu'il s'agit de boîtiers métalliques, leur emplacement joue un grand rôle et peut même aller jusqu'à diminuer l'ITS de 6 points. On peut donc faire attention à leur emplacement, mais on peut également insérer des absorbants acoustiques qui s'avèrent parfois efficaces. La présence de boîtiers électriques peut avoir un effet néfaste sur la résistance au feu des cloisons.

description: Magnetism in 2D networks of the acetylene-bridged transition metal porphyrins M(P)-2(C-C)-2 (denoted P-TM), and oxo-TM-porphyrins OM(P)-2(C-C)-2 (denoted P-TMO), is studied with the density functional theory (DFT) and the self-interaction corrected pseudopotential scheme (pSIC). Addition of oxygen lowers magnetism of P-TMO with respect to the corresponding P-TM for most of the first-half $3d$-row TMs. In contrast, binding O with the second-half $3d$-row TMs or Sc increases the magnetic moments. Ferrimagnetism is found for the porphyrin networks with the TMs from V to Co and also for these cases with oxygen. This is a long-range effect of the delocalized spin-polarization, extended even to the acetylene bridges.

Reducing Bias Due to Exposure Measurement Error Using Disease Risk Scores

Publisher: name: Oxford University Press

description: Suppose that an investigator wants to estimate an association between a continuous exposure variable and an outcome, adjusting for a set of confounders. If the exposure variable suffers classical measurement error, in which the measured exposures are distributed with independent error around the true exposure, then an estimate of the covariate-Adjusted exposure-outcome association may be biased. We propose an approach to estimate a marginal exposure-outcome association in the setting of classical exposure measurement error using a disease score-based approach to standardization to the exposed sample. First, we show that the proposed marginal estimate of the exposure-outcome association will suffer less bias due to classical measurement error than the covariate-conditional estimate of association when the covariates are predictors of exposure. Second, we show that if an exposure validation study is available with which to assess exposure measurement error, then the proposed marginal estimate of the exposure-outcome association can be corrected for measurement error more efficiently than the covariate-conditional estimate of association. We illustrate both of these points using simulations and an empirical example using data from the Orinda Longitudinal Study of Myopia (California, 1989-2001).

description: The nonrelativistic quantum dynamics of a spinless charged particle in the presence of the Aharonov--Bohm potential in curved space is considered. We chose the surface as being a cone defined by a line element in polar coordinates. The geometry of this line element establishes that the motion of the particle can occur on the surface of a cone or an anti--cone. As a consequence of the nontrivial topology of the cone and also because of two--dimensional confinement, the geometric potential should be taken into account. At first, we establish the conditions for the particle describing a circular path in such a context. Because of the presence of the geometric potential, which contains a singular term, we use the self--adjoint extension method in order to describe the dynamics in all space including the singularity. Expressions are obtained for the bound state energies and wave functions.

description: Measures of information and surprise, such as the Shannon information value (S value), quantify the signal present in a stream of noisy data. We illustrate the use of such information measures in the context of interpreting P values as compatibility indices. S values help communicate the limited information supplied by conventional statistics and cast a critical light on cutoffs used to judge and construct those statistics. Misinterpretations of statistics may be reduced by interpreting P values and interval estimates using compatibility concepts and S values instead of "significance"and "confidence."
THE ROLE OF TEACHER COLLABORATION IN IMPROVING STUDENT OUTCOMES

description: Teacher collaboration has emerged as a crucial factor in enhancing educational practices and improving student outcomes. This paper explores the significance of collaborative efforts among teachers, focusing on how collective planning, sharing of resources, and mutual support can lead to enriched teaching environments and better student performance. Through a comprehensive review of various studies and practical experiences, the paper examines the methodologies employed to facilitate collaboration, the impact of such initiatives on student achievement, and the challenges faced by educators in fostering a collaborative culture. The findings suggest that when teachers engage collaboratively, they are more effective in addressing diverse student needs, implementing innovative strategies, and ultimately, driving student success.
Matrix elements of $ΔB=0$ operators in heavy hadron chiral perturbation theory

description: We study the light-quark mass and spatial volume dependence of the matrix elements of $ΔB=0$ four-quark operators relevant for the determination of $V_{ub}$ and the lifetime ratios of single-$b$ hadrons. To this end, one-loop diagrams are computed in the framework of heavy hadron chiral perturbation theory with partially quenched formalism for three light-quark flavors in the isospin limit; flavor-connected and -disconnected diagrams are carefully analyzed. These calculations include the leading light-quark flavor and heavy-quark spin symmetry breaking effects in the heavy hadron spectrum. Our results can be used in the chiral extrapolation of lattice calculations of the matrix elements to the physical light-quark masses and to infinite volume. To provide insight on such chiral extrapolation, we evaluate the one-loop contributions to the matrix elements containing external $B_d$, $B_s$ mesons and $Λ_b$ baryon in the QCD limit, where sea and valence quark masses become equal. In particular, we find that the matrix elements of the $λ_3$ flavor-octet operators with external $B_d$ meson receive the contributions solely from connected diagrams in which current lattice techniques are capable of precise determination of the matrix elements. Finite volume effects are at most a few percent for typical lattice sizes and pion masses.

title: Reading the post-postmodern formal strategies of David Foster Wallace and Mark Z Danielewski
Creators: name: Michael Hering, David
Publisher: name: University of Liverpool Repository
Year: 2023

description: This thesis addresses the formal narrative strategies of two American authors, David Foster Wallace and Mark Z Danielewski, in terms of their relationship to postmodernism. Wallace's novel Infinite Jest (1996) and Danielewski's debut House of Leaves (2000) are substantial works, with an encyclopedic employment of large amounts of information (Wallace's novel fW1S to around 1,100 pages, while Dani()1ewski's is a little over 700 pages) and complex structuring principles. These .Jwo novels also represent the most explicit and lengthy programmatic dialogue with postmodernism that these writers have produced. The only manner in which to engage in serious and close critical detail with this element of Danielewski's and Wallace's formal strategies is to study these works in close and lengthy detail. Therefore, Infinite Jest and House of Leaves are the basis of this study, with references made to other works by Wallace and Danielewski where appropriate. It is the contention of this study that, while it has been critically posited that Infinite Jest occupies a position that is interrogative of the tenets of postmodernism, no critic has yet outlined in extensive detail Wallace's crucial employment of specifically formal narrative strategies to dramatise this interrogation. Furthermore, critical positions on House of Leaves are only just beginning to consider that the novel might adopt an combative position towards postmodem tropes. This study suggests the essential importance of reading Danielewski's novel as a post-postmodern text by outlining how, through its formal narrative strategies, the novel dramatises and interrogates its own roots within postmodernism. "Form" in this study is taken to mean both the pervasive employment of particular spatial, temporal and paratextual tropes to construct a narrative with a particular "shape", as well as an interaction and hybridisation with other, non-literary forms. The critical analysis within this study reveals the remarkable similarity of the formal narrative strategies ofthe two writers, with both Wallace and Danielewski employing a number of formal structuring principles that underpin the spatiotemporal form of their works, principles that draw from (among other areas) mathematics, poststructuralism and cultural theory in order to enact an interrogation of postmodern tropes. This study also suggests that the formal employment of cinematic terminology, theory and technique within both Infinite Jest and House of Leaves is substantial and fundamental to the post-postmodern position of both works.

description: We present faster algorithms for computing the 2-edge and 2-vertex strongly connected components of a directed graph, which are straightforward generalizations of strongly connected components. While in undirected graphs the 2-edge and 2-vertex connected components can be found in linear time, in directed graphs only rather simple $O(m n)$-time algorithms were known. We use a hierarchical sparsification technique to obtain algorithms that run in time $O(n^2)$. For 2-edge strongly connected components our algorithm gives the first running time improvement in 20 years. Additionally we present an $O(m^2 / \log{n})$-time algorithm for 2-edge strongly connected components, and thus improve over the $O(m n)$ running time also when $m = O(n)$. Our approach extends to k-edge and k-vertex strongly connected components for any constant k with a running time of $O(n^2 \log^2 n)$ for edges and $O(n^3)$ for vertices.
title: Monitoring partial discharge signals using a chromatic approach
Creators: name: Ragaa, Mohamed
Publisher: name: University of Liverpool Repository
Year: 2023

description: A novel approach for extracting information about the insulation integrity of a dielectric from Partial Discharge (PD) signals is described. The approach is based upon chromatic methodologies and involves addressing PD signals with three processors having non-orthogonal (overlapping) responses. The outputs of the three processors are transformed into a number of chromatic parameters designated x, y, z and H, L, S. x, y, z represent the proportion of the signal from each of the three processors. H, L, S represent respectively the dominant phase, effective strength and notional spread of the PD signals. A range of Partial Discharge signals obtained by various researchers worldwide have been analysed using the chromatic approach. These include investigations on various dielectrics (epoxy resins, impregnated oil, Perspex ... etc) which exhibited complete insulation breakdown, as well as PD signals generated from different PD sources have been analysed using the approach. Changes in the values of the chromatic parameters are shown to reflect various PD trends and to provide early indications of incipient insulation failure and PD source discrimination. The approach provides a high degree of traceability in relating the chromatic parameters to the raw PD signals

description: Justification logics are epistemic logics that explicitly include justifications for the agents' knowledge. We develop a multi-agent justification logic with evidence terms for individual agents as well as for common knowledge. We define a Kripke-style semantics that is similar to Fitting's semantics for the Logic of Proofs LP. We show the soundness, completeness, and finite model property of our multi-agent justification logic with respect to this Kripke-style semantics. We demonstrate that our logic is a conservative extension of Yavorskaya's minimal bimodal explicit evidence logic, which is a two-agent version of LP. We discuss the relationship of our logic to the multi-agent modal logic S4 with common knowledge. Finally, we give a brief analysis of the coordinated attack problem in the newly developed language of our logic.
title: Electrochemical properties of redox centres in coordination compounds and in gold nanocluster hybrids
Creators: name: Cabo Fernández, Laura
Publisher: name: University of Liverpool Repository
Year: 2023

description: In the present work the properties of compounds that can display conformational switching and Coulomb blockade features as a result of electron transfer reactions have been investigated with a view to observing possible Negative Differential Resistance behaviour. This phenomenon is sometimes associated with oscillatory processes and could broaden the field of applications of nanoparticles such as for electronic devices and storage memories. Copper coordination compounds with macro cyclic ligands change their geometry from a distorted octahedral conformation, for Cu(II), to a tetrahedral geometry, for Cu(I), upon reduction of the metal centre. In the research described in this Thesis, copper was coordinated to tetradentante macrocycles with two types of donor sets, tetra-amine (i.e., N4) and macrocycles containing sulfur and nitrogen atoms (i.e., N2S2). It was found that increasing the cavity dimensions of the ligand, the copper(II) complexes were destabilised leading to a shift in the reduction potential to more positive values. The presence of tertiary amines and soft electron-donating atoms such as sulfur in the structure of the ligands favours the formation of Cu(I) intermediates in comparison with Cu(II) species. Rate constants for the electron transfer reactions and chemical steps for these reactions were estimated using computer simulations. Hexanethiolate gold clusters with an average core diameter of 1.8 nm and a calculated capacitance of 0.6 aF were synthesised using a two-phase method. These clusters presented Coulomb blockade responses due to Quantised Double-Layer charging (QDL) events in voltammetric studies. These nanoparticles were functionalised by a place-exchange reaction and terminal bromine groups were introduced by reaction with l l-bromo-l-undecanethiol. The clusters thus synthesised preserved the core single-charging events and served as precursors for the synthesis of hybrids with copper complexes via a nucleophilic substitution reaction. Place-exchange with 6-(ferrocenyl)-1-hexanethiol was also carried out to incorporate ferrocene centres on the cluster surface. Voltammetric measurements showed the redox response of the F c +/F c couple and the charging events of the gold core. A transition in the behaviour from single to multiple electron transfer response for the redox couple was observed as the number of ferrocene units per cluster was increased. For multiple electron transfer processes, a mechanism in which the core acts as a mediator has been proposed involving electron tunnelling through the chains linking the redox centre to the gold core.

The system is able to observe the sky simultaneously in either wide (~900 square degrees) or narrow (~100 square degrees) fields of view, either in clear light or with any combination of color (Johnson B, V or R) polarimetric filters installed, with exposure times ranging from 100 ms to 100 s. The primary goal of the system is the detection of rapid -- with sub-second characteristic time-scales -- optical transients, but it may be also used for studying the variability of the sky objects on longer time scales.

Year: 2021

description: The coronavirus disease 2019 (COVID-19) pandemic and the coming transition to a postpandemic world where COVID-19 will likely remain as an endemic disease present a host of challenges and opportunities in epidemiologic research. The scale and universality of this disruption to life and health provide unique opportunities to study phenomena and health challenges in all branches of epidemiology, from the obvious infectious disease and social consequences to less clear impacts on chronic disease and cancer. If we are to both take advantage of the largest natural experiment of our lifetimes and provide evidence to inform the numerous public health and clinical decisions being made every day, we must act quickly to ask critical questions and develop new methods for answering them. In doing so, we should build on each of our strengths and expertise and try to provide new insights rather than become yet another voice commenting on the same set of questions with limited evidence.
What does the proof of Birnbaum's theorem prove?

Subjects: subject: Statistics Theory (math.ST)

description: Birnbaum's theorem, that the sufficiency and conditionality principles entail the likelihood principle, has engendered a great deal of controversy and discussion since the publication of the result in 1962. In particular, many have raised doubts as to the validity of this result. Typically these doubts are concerned with the validity of the principles of sufficiency and conditionality as expressed by Birnbaum. Technically it would seem, however, that the proof itself is sound. In this paper we use set theory to formalize the context in which the result is proved and show that in fact Birnbaum's theorem is incorrectly stated as a key hypothesis is left out of the statement. When this hypothesis is added, we see that sufficiency is irrelevant, and that the result is dependent on a well-known flaw in conditionality that renders the result almost vacuous.

As an application, we prove the existence and uniqueness of the integral curve of a vector field on $M$.

description: Malaria remains a significant cause of morbidity and mortality in Malawi, with an estimated 18–19% prevalence of Plasmodium falciparum in children 2–10 years in 2015–2016. While children report the highest rates of clinical disease, adults are thought to be an important reservoir to sustained transmission due to persistent asymptomatic infection. The 2015–2016 Malawi Demographic and Health Survey was a nationally representative household survey which collected dried blood spots from 15,125 asymptomatic individuals ages 15–54 between October 2015 and February 2016. We performed quantitative polymerase chain reaction on 7,393 samples, detecting an overall P. falciparum prevalence of 31.1% (SE = 1.1). Most infections (55.6%) had parasitemias ≤ 10 parasites/µL. While 66.2% of individuals lived in a household that owned a bed net, only 36.6% reported sleeping under a long-lasting insecticide-treated net (LLIN) the previous night. Protective factors included urbanicity, greater wealth, higher education, and lower environmental temperatures. Living in a household with a bed net (prevalence difference 0.02, 95% CI − 0.02 to 0.05) and sleeping under an LLIN (0.01; − 0.02 to 0.04) were not protective against infection. Our findings demonstrate a higher parasite prevalence in adults than published estimates among children. Understanding the prevalence and distribution of asymptomatic infection is essential for targeted interventions.

description: In this paper, we study Lipschitz-Fredholm vector fields on Bounded-Fréchet-Finsler manifolds. In this context we generalize the Morse-Sard-Brown theorem, asserting that if $M$ is a connected smooth bounded-Fréchet-Finsler manifold endowed with a strengthened connection $\mathcal{K}$ and if $ξ$ is a smooth Lipschitz-Fredholm vector field on $M$ with respect to $\mathcal{K}$ which satisfies condition (CV). Then, for any smooth functional $l$ on $M$ which is associated to $ξ$, the set of the critical values of $l$ is of the first category in $\rr$. Therefore, the set of the regular values of $l$ is a residual Baire subset of $\mathbb{R}$.

description: We introduce a new Gentzen-style framework of grafted hypersequents that combines the formalism of nested sequents with that of hypersequents. To illustrate the potential of the framework, we present novel calculi for the modal logics $\mathsf{K5}$ and $\mathsf{KD5}$, as well as for extensions of the modal logics $\mathsf{K}$ and $\mathsf{KD}$ with the axiom for shift reflexivity. The latter of these extensions is also known as $\mathsf{SDL}^+$ in the context of deontic logic. All our calculi enjoy syntactic cut elimination and can be used in backwards proof search procedures of optimal complexity. The tableaufication of the calculi for $\mathsf{K5}$ and $\mathsf{KD5}$ yields simplified prefixed tableau calculi for these logic reminiscent of the simplified tableau system for $\mathsf{S5}$, which might be of independent interest.

description: We have recently presented a general method of proving the fundamental logical properties of Craig and Lyndon Interpolation (IPs) by induction on derivations in a wide class of internal sequent calculi, including sequents, hypersequents, and nested sequents. Here we adapt the method to a more general external formalism of labelled sequents and provide sufficient criteria on the Kripke-frame characterization of a logic that guarantee the IPs. In particular, we show that classes of frames definable by quantifier-free Horn formulas correspond to logics with the IPs. These criteria capture the modal cube and the infinite family of transitive Geach logics.

description: We introduce the notion of $T$-stability for torsion-free Higgs sheaves as a natural generalization of the notion of $T$-stability for torsion-free coherent sheaves over compact complex manifolds. We prove similar properties to the classical ones for Higgs sheaves. In particular, we show that only saturated flags of torsion-free Higgs sheaves are important in the definition of $T$-stability. Using this, we show that this notion is preserved under dualization and tensor product with an arbitrary Higgs line bundle. Then, we prove that for a torsion-free Higgs sheaf over a compact Kähler manifold, $ω$-stability implies $T$-stabilty. As a consequence of this we obtain the $T$-semistability of any reflexive Higgs sheaf with an admissible Hermitian-Yang-Mills metric. Finally, we prove that $T$-stability implies $ω$-stability if, as in the classical case, some additional requirements on the base manifold are assumed. In that case, we obtain the existence of admissible Hermitian-Yang-Mills metrics on any $T$-stable reflexive sheaf.

description: BACKGROUND: National-level population size estimates (PSEs) for hidden populations are required for HIV programming and modelling. Various estimation methods are available at the site-level, but it remains unclear which are optimal and how best to obtain national-level estimates.Zimbabwe. METHODS: Using 2015-2017 data from respondent-driven sampling (RDS) surveys among female sex workers (FSW) aged 18+ years, mappings, and program records, we calculated PSEs for each of the 20 sites across Zimbabwe, using up to 3 methods per site (service and unique object multipliers, census, and capture-recapture). We compared estimates from different methods, and calculated site medians. We estimated prevalence of sex work at each site using census data available on the number of 15-49-year-old women, generated a list of all "hotspot" sites for sex work nationally, and matched sites into strata in which the prevalence of sex work from sites with PSEs was applied to those without. Directly and indirectly estimated PSEs for all hotspot sites were summed to provide a national-level PSE, incorporating an adjustment accounting for sex work outside hotspots. RESULTS: Median site PSEs ranged from 12,863 in Harare to 247 in a rural growth-point. Multiplier methods produced the highest PSEs. We identified 55 hotspots estimated to include 95% of all FSW. FSW nationally were estimated to number 40,491, 1.23% of women aged 15-49 years, (plausibility bounds 28,177-58,797, 0.86-1.79%, those under 18 considered sexually exploited minors). CONCLUSION: There are large numbers of FSW estimated in Zimbabwe. Uncertainty in population size estimation should be reflected in policy-making.

description: BACKGROUND: Nearly all population-level research showing positive associations between age-disparate partnerships and HIV acquisition among adolescent girls and young women (AGYW) has classified age disparity as ≥5 or ≥10 years. We describe variations in 1-year risk of HIV infection after exposure to sexual partner(s) of continuous age disparities. METHODS: Longitudinal data from the HPTN 068 randomized trial in South Africa were used to estimate 1-year risk of HIV infection at various age pairings. The parametric g-formula was used to estimate risk at up to 5 annual time points, stratified by maximum partner age difference, maximum partner age, and AGYW age. RESULTS: AGYW reported an older partner in 86% of 5351 age pairings. The 1-year risk of HIV infection rapidly increased with maximum partner age difference among girls ages 13-14 years, from 0·01 with a same-age partner, to 0·21 with a partner 10 years older, and 0·24 with a partner 15 years older. A gradual increase occurred among AGYW ages 15-16 years, up to 0·13 with a partner 15 years older, and 0·09 among AGYW 17-18 years with partners 8-11 years older. Risk of HIV infection among AGYW ages 19-21 years remained relatively constant across maximum partner age differences. CONCLUSIONS: Age differences between AGYW and their sexual partners have a greater effect on HIV-risk infection in younger compared with older AGYW. Considering both the age of an AGYW and her sexual partners provides granular insight into identifying key groups for HIV transmission prevention efforts.

description: We consider some versions and generalizations of an approach to the expansion of iterated Ito stochastic integrals of arbitrary multiplicity $k$ $(k\in\mathbb{N})$ based on generalized multiple Fourier series. Expansions of iterated stochastic integrals with respect to martingale Poisson measures and with respect to martingales were obtained. For the iterated stochastic integrals with respect to martingales we have proved theorem, which is a generalization of the expansion for iterated Ito stochastic integrals of arbitrary multiplicity based on generalized multiple Fourier series. Also we consider a modification of the mentioned expansion of iterated Ito stochastic integrals for the case of complete orthonormal with weight $r(t_1)\ldots r(t_k)\ge 0$ systems of functions in the space $L_2([t, T]^k)$. Mean-square convergence of the considered expansions is proved. An example of the expansion of iterated (double) stochastic integrals with respect to martingales using the system of Bessel functions is considered.

Unique Quasi-Stationary Distribution, with a possibly stabilizing extinction

description: We establish sufficient conditions for exponential convergence to a unique quasi-stationary distribution in the total variation norm. These conditions also ensure the existence and exponential ergodicity of the Q-process, the process conditionned upon never being absorbed. The technique relies on a coupling procedure that is related to Harris recurrence (for Markov Chains). It applies to general continuous-time and continuous-space Markov processes. The main novelty is that we modulate each coupling step depending both on a final horizon of time (for survival) and on the initial distribution. By this way, we could notably include in the convergence a dependency on the initial condition. As an illustration, we consider a continuous-time birth-death process with catastrophes and a diffusion process describing a (localized) population adapting to its environment.

description: We present results of global fits of all relevant experimental data on rare $b \to s$ decays. We observe significant tensions between the Standard Model predictions and the data. After critically reviewing the possible sources of theoretical uncertainties, we find that within the Standard Model, the tensions could be explained if there are unaccounted hadronic effects much larger than our estimates. Assuming hadronic uncertainties are estimated in a sufficiently conservative way, we discuss the implications of the experimental results on new physics, both model independently as well as in the context of the minimal supersymmetric standard model and models with flavour-changing $Z'$ bosons. We discuss in detail the violation of lepton flavour universality as hinted by the current data and make predictions for additional lepton flavour universality tests that can be performed in the future. We find that the ratio of the forward-backward asymmetries in $B \to K^* μ^+μ^-$ and $B \to K^* e^+e^-$ at low dilepton invariant mass is a particularly sensitive probe of lepton flavour universality and allows to distinguish between different new physics scenarios that give the best description of the current data.

description: For a compact quantum group $\mathbb G$ of Kac type, we study the existence of a Haar trace-preserving embedding of the von Neumann algebra $L^\infty(\mathbb G)$ into an ultrapower of the hyperfinite II$_1$-factor (the Connes embedding property for $L^\infty(\mathbb G)$). We establish a connection between the Connes embedding property for $L^\infty(\mathbb G)$ and the structure of certain quantum subgroups of $\mathbb G$, and use this to prove that the II$_1$-factors $L^\infty(O_N^+)$ and $L^\infty(U_N^+)$ associated to the free orthogonal and free unitary quantum groups have the Connes embedding property for all $N \ge 4$. As an application, we deduce that the free entropy dimension of the standard generators of $L^\infty(O_N^+)$ equals $1$ for all $N \ge 4$. We also mention an application of our work to the problem of classifying the quantum subgroups of $O_N^+$.
