description: We used the mental models research method to generate a conceptual map of how Midwest farmers use knowledge, experience, and individual perceptions of weed-related risk to make weed management decisions. We discovered that Midwest farmer knowledge of ecological weed management practices is robust, and that the difficult trade-offs farmers make regarding cultivation, cover crops, and soil health determine what weed management practices they use. Midwest farmers balance the risks of cultivation and implementation of cover crops with their valuable benefits to soil health and weed suppression. Developing a decision support tool that provides a baseline of scientific evidence and that offers flexibility based on farmers’ experiences and values will clarify these trade-offs and guide effective decision-making.

description: We present a pipeline for parametric wireframe extraction from densely sampled point clouds. Our approach processes a scalar distance field that represents proximity to the nearest sharp feature curve. In intermediate stages, it detects corners, constructs curve segmentation, and builds a topological graph fitted to the wireframe. As an output, we produce parametric spline curves that can be edited and sampled arbitrarily. We evaluate our method on 50 complex 3D shapes and compare it to the novel deep learning-based technique, demonstrating superior quality.

description: The recently-discovered centre-mode instability of rectilinear viscoelastic shear flow (Garg et al. Phy. Rev. Lett. 121, 024502, 2018) has offered an explanation for the origin of elasto-inertial turbulence (EIT) which occurs at lower Weissenberg ($Wi$) numbers. In support of this, we show using weakly nonlinear analysis that the subcriticality found in Page et al. (Phys. Rev. Lett. 125, 154501, 2020) is generic across the neutral curve with the instability only becoming supercritical at low Reynolds ($Re$) numbers and high $Wi$. We demonstrate that the instability can be viewed as purely elastic in origin even for $Re=O(10^3)$, rather than `elasto-inertial', as the underlying shear does not energise the instability. It is also found that the introduction of a realistic maximum polymer extension length, $L_{max}$, in the FENE-P model moves the neutral curve closer to the inertialess $Re=0$ limit at a fixed ratio of solvent-to-solution viscosities, $β$. In the dilute limit ($β\rightarrow 1$) with $L_{max} =O(100)$, the linear instability can brought down to more physically-relevant $Wi\gtrsim 110$ at $β=0.98$, compared with the threshold $Wi=O(10^3)$ at $β=0.994$ reported recently by Khalid et al. (arXiv: 2103.06794) for an Oldroyd-B fluid. Again the instability is subcritical implying that inertialess rectilinear viscoelastic shear flow is nonlinearly unstable - i.e. unstable to finite amplitude disturbances - for even lower $Wi$.

description: Sedentary behavior has already been associated with mortality, cardiovascular disease, and cancer. Questionnaires are an affordable tool for measuring sedentary behavior in large epidemiological studies. Here, we introduce and evaluate two statistical methods for quantifying measurement error in questionnaires. Accurate estimates are needed for assessing questionnaire quality. The two methods would be applied to validation studies that measure a sedentary behavior by both questionnaire and accelerometer on multiple days. The first method fits a reduced model by assuming the accelerometer is without error, while the second method fits a more complete model that allows both measures to have error. Because accelerometers tend to be highly accurate, we show that ignoring the accelerometer's measurement error, can result in more accurate estimates of measurement error in some scenarios. In this article, we derive asymptotic approximations for the mean-squared error of the estimated parameters from both methods, evaluate their dependence on study design and behavior characteristics, and offer an R package so investigators can make an informed choice between the two methods. We demonstrate the difference between the two methods in a recent validation study comparing previous day recalls to an accelerometer-based ActivPal.

description: Higher order finite difference Weighted Essentially Non-Oscillatory (WENO) schemes for conservation laws represent a technology that has been reasonably consolidated. They are extremely popular because, when applied to multidimensional problems, they offer high order accuracy at a fraction of the cost of finite volume WENO or DG schemes. They come in two flavors. There is the classical finite difference WENO (FD-WENO) method (Shu and Osher, J. Comput. Phys., 83 (1989) 32-78). However, in recent years there is also an alternative finite difference WENO (AFD-WENO) method which has recently been formalized into a very useful general-purpose algorithm for conservation laws (Balsara et al., Efficient Alternative Finite Difference WENO Schemes for Hyperbolic Conservation Laws, submitted to CAMC (2023)). However, the FD-WENO algorithm has only very recently been formulated for hyperbolic systems with non-conservative products (Balsara et al., Efficient Finite Difference WENO Scheme for Hyperbolic Systems with Non-Conservative Products, to appear CAMC (2023)). In this paper we show that there are substantial advantages in obtaining an AFD-WENO algorithm for hyperbolic systems with non-conservative products. Such an algorithm is documented in this paper. We present an AFD-WENO formulation in fluctuation form that is carefully engineered to retrieve the flux form when that is warranted and nevertheless extends to non-conservative products. The method is flexible because it allows any Riemann solver to be used. The formulation we arrive at is such that when non-conservative products are absent it reverts exactly to the formulation in the second citation above which is in exact flux conservation form. The ability to transition to a precise conservation form when non-conservative products are absent ensures, via the Lax-Wendroff theorem, that shock locations will be exactly ...

description: Goal oriented autonomous operation of space rovers has been known to increase scientific output of a mission. In this work we present an algorithm, called the RoI Prioritised Sampling (RPS), that prioritises Region-of-Interests (RoIs) in an exploration scenario in order to utilise the limited resources of the imaging instrument on the rover effectively. This prioritisation is based on an estimator that evaluates the change in information content at consecutive spatial scales of the RoIs without calculating the finer scale reconstruction. The estimator, called the Refinement Indicator (RI), is motivated and derived. Multi-scale acquisition approaches, based on classical and multilevel compressed sensing, with respect to the single pixel camera architecture are discussed. The performance of the algorithm is verified on remote sensing images and compared with the state-of-the-art multi-resolution reconstruction algorithms. At the considered sub-sampling rates the RPS is shown to better utilise the system resources for reconstructing the RoIs.

description: Quantum key distribution (QKD) is an ingenious technology utilizing quantum information science for provable secure communication. However, owing to the technological limitations and device non-idealities it is important to analyze the system performance critically and carefully define the implementation security. With an acceleration in the commercial adoption of QKD, a simulation toolkit is requisite to evaluate the functional architecture of QKD protocols. We present a simulation framework to model optical and electrical components for implementing a QKD protocol. The present toolkit aims to model and simulate the optical path of the DPS-QKD protocol with its imperfections and eventually characterize the optical path. The detailed device-level modeling and analysis capabilities of the present toolkit based on Simulink and MATLAB have the potential to provide universal toolkit for practical design and implementation of generalized QKD protocols compared to earlier works. We report a novel work on the implementation of a QKD protocol on Simulink and MATLAB platform. Further, the absence of any modeling framework for DPS QKD and its simplistic optical schematic made it an obvious choice for the authors. We are hopeful that this work will pave way for simulating other QKD protocols from the DPR family.

description: The axion solution to the strong CP problem is delicately sensitive to Peccei-Quinn breaking contributions that are misaligned with respect to QCD instantons. Heavy QCD axion models are appealing because they avoid this so-called "quality problem". We show that generic realizations of this framework can be probed by the LIGO-Virgo-KAGRA interferometers, through the stochastic gravitational wave (GW) signal sourced by the long-lived axionic string-domain wall network, and by upcoming measurements of the neutron and proton Electric Dipole Moments. Additionally, we provide predictions for searches at future GW observatories, which will further explore the parameter space of heavy QCD axion models.

description: We use a geometric method to derive (two-dimensional) separation functions amongst pairs of objects within populations of specified position function $\mathrm{d} N/\mathrm{d} \vec{R}$. We present analytic solutions for separation functions corresponding to a uniform surface density within a circular field, a Plummer sphere (viewed in projection), and the mixture thereof -- including contributions from binary objects within both sub-populations. These results enable inferences about binary object populations via direct modeling of object position and pair separation data, without resorting to standard estimators of the two-point correlation function. Analyzing mock data sets designed to mimic known dwarf spheroidal galaxies, we demonstrate the ability to recover input properties including the number of wide binary star systems and, in cases where the number of resolved binary pairs is assumed to be $\gtrsim$ a few hundred, characteristic features (e.g., steepening and/or truncation) of their separation function. Combined with forthcoming observational capabilities, this methodology opens a window onto the formation and/or survival of wide binary populations in dwarf galaxies, and offers a novel probe of dark matter substructure on the smallest galactic scales.

description: We find half-wormhole solutions in Jackiw-Teitelboim gravity by allowing the geometry to end on a spacetime D-brane with specific boundary conditions. This theory also contains a Euclidean wormhole which leads to a factorization problem. We propose that half-wormholes provide a gravitational picture for how factorization is restored and show that the Euclidean wormhole emerges from averaging over the boundary conditions. The wormhole is known to be dual to a Sachdev-Ye-Kitaev (SYK) model with random complex couplings. We find that the free energy of the half-wormhole is strikingly similar to that of a single realization of this SYK model. These results suggest that the gravitational path integral computes an average over spacetime D-brane boundary conditions.

Dependence of band gaps in d-electron perovskite oxides on magnetism

description: Understanding the controlling principles of band gaps trends in d electron perovskites is needed both for gauging metal-insulator transitions, as well as their application in catalysis and doping. The magnitude of this band gap is rather different for different magnetic spin configurations. We find via electronic structure theory that the factors that connect gapping magnitudes to magnetism depend on the nature of the band edge orbital character (BEOC) and surprisingly scale with the number of antiferromagnetic contacts z$_i$ between neighboring transition metal ions. The dependence is weak when the BEOC are (d,d)-like ("Mott insulators"), whereas this dependence is rather strong in (p,d)-like ("charge transfer" insulators). These unexpected rules are traced to the reduced orbital interactions through the increase in the number of antiferromagnetic contacts between transition metal ions. The impact of magnetic order is not limited to the band gap magnitude and includes also the magnitude of lattice distortions connected to the electronic structure. These results highlight the importance of establishing in electronic structure theory of gap-related phenomena (doping, transport, metal-insulator transitions, conductive interfaces) the appropriate magnetic order.

description: Objective: To assess the experiences of hypoglycemia in drivers with type 2 diabetes according to types of diabetes treatment; to determine experiences in different driving groups; and to ascertain whether UK-based Driving and Vehicle Licensing Agency (DVLA) guidance concerning hypoglycemia and driving is understood. Research, design, and methods: An online questionnaire was sent to UK drivers with type 2 diabetes between June and September 2014. Study limitations included selection bias inherent in online surveys, and lack of validation of the definition of hypoglycemic symptoms by an expert patient group. Results: The survey was completed by 1569 (457 social, 590 commuters, and 522 business/work) drivers. Vocational drivers were more likely to be treated with an insulin secretagogue (sulfonylureas and glinides) (52%) than diet alone (18%), a non-insulin secretagogue (26%) or insulin (16%). Symptoms of hypoglycemia (both mild and severe) were reported by 62% of the total cohort in the past year. Risk was greatest in those with poor diabetes self-management behavior and those receiving an insulin secretagogue. Among the 1112 respondents commuting or driving for a living, 16.8% had poor, 49.6% average, and 33.6% good diabetes self-management. Poor self-management was more frequent among vocational drivers and those receiving insulin secretagogues. Following a hypoglycemic episode, only 24% of insulin-secretagogue-treated drivers and 39% of insulin-treated drivers would discontinue driving for the DVLA-recommended 45 minutes. Insulin-treated drivers were best informed about diabetes and driving. Healthcare providers were the preferred source of information on driving and diabetes for 78% of drivers. Conclusion: Hypoglycemia risk is highest among drivers with poor diabetes self-management, those commuting or driving for a living and those taking insulin secretagogues. There is an educational need for all drivers concerning driving and hypoglycemia.

description: The purpose of this note is to describe when a general complex algebraic $^*$-algebra is pre-$C^*$-normed, and to investigate their structure when the $^*$-algebras are Baer $^*$-rings in addition to algebraicity. As a main result we prove the following theorem for complex algebraic Baer $^*$-algebras: every $^*$-algebra of this kind can be decomposed as a direct sum $M\oplus B$, where $M$ is a finite dimensional Baer $^*$-algebra and $B$ is a commutative algebraic Baer $^*$-algebra. The summand $M$ is $^*$-isomorphic to a finite direct sum of full complex matrix algebras of size at least $2\times2$. The commutative summand $B$ is $^*$-isomorphic to the linear span of the characteristic functions of the clopen sets in a Stonean topological space. As an application we show that a group $G$ is finite exactly when the complex group algebra $\mathbb{C}[G]$ is an algebraic Baer $^*$-algebra.

description: We perform an extensive numerical study on the breathing dynamics of a few-body Bose polaron setup in a one-dimensional species-selective harmonic trap. The dynamics is triggered by a quench of the impurity trap. The excitation of the background majority atoms is mediated via the majority-impurity interaction. The breathing spectrum is obtained for different numbers of majority particles, several values of the majority-component interaction strengths and trap ratios. It is further compared to the breathing spectrum of a particle-balanced few-body Bose-Bose mixture. In particular, for equal post-quench traps the employed protocol allows to couple states of different center-of-mass parity in contrast to species-symmetric trap quenches. Among the participating eigenstates we identify one having odd center-of-mass parity and even global parity. The breathing frequency induced by this state is a monotonically decreasing function of the coupling parameter. Importantly, in order to be observable it requires the entanglement between the species to be taken into account. We demonstrate this by comparing the numerically exact results obtained by means of the Multi-Layer Multi-Configuration Time-Dependent Hartree Method for Mixtures to the ones of a species mean-field ansatz. The entanglement-sensitive breathing frequency persists also for unequal post-quench traps where the center-of-mass cannot be decoupled. Finally, we analyze the impact of parity symmetry on the breathing dynamics by initializing a state of odd global parity. We evidence a striking resemblance to the ground state breathing dynamics.

A local velocity grid conservative semi-Lagrangian schemes for BGK model

description: Most numerical schemes proposed for solving BGK models for rarefied gas dynamics are based on the discrete velocity approximation. Since such approach uses fixed velocity grids, one must secure a sufficiently large domain with fine velocity grids to resolve the structure of distribution functions. When one treats high Mach number problems, the computational cost becomes prohibitively expensive. In this paper, we propose a velocity adaptation technique in the semi-Lagrangian framework for BGK model. The velocity grid will be set locally in time and space, according to mean velocity and temperature. We apply a weighted minimization approach to impose conservation. We presented several numerical tests that illustrate the effectiveness of our proposed scheme.
The Virtual Time Travel Platform : engineering a generic framework for immersive cultural heritage scenes
Creators: name: McCaffery, John
Publisher: name: University of St Andrews
Year: 2015

description: This thesis presents the Virtual Time Travel Platform (VTTP), a flexible platform for creating, sharing and deploying interactive cultural heritage content across a diverse range of contexts. The interactive scenes created using the VTTP enable experiential learning on cultural heritage topics. The VTTP supports the creation of scenes using freely available tools. These scenes can then be deployed into museums, schools and across the Internet through a process of reconfiguration rather than redevelopment. The VTTP enables high tech, immersive exhibits to be produced with a budget and a flexibility that is suitable for co-creation with community museums as opposed to national institutions. To date the VTTP has been used to deploy three heterogenous museum exhibits across Scotland which have been visited by more than 10,000 visitors in the 18 months since the first one went live. This thesis presents an evaluation of the success of these exhibits at engaging the public with the topics they present. The VTTP was created by augmenting existing Open Virtual World (OVW) software (OpenSim) to support installation into museums. The component which adds this functionality is a bespoke application called Chimera. Chimera supports immersive displays, Natural User Input (NUI) control and the embedding of experiential exploration as part of a larger context suitable for museums. The extension of OVW technology to enable museum deployment is the major contribution of this work. To support the museum deployments a quantitative analysis of the VTTP Viewer component is presented. This evaluates the impact of Viewer quality of service onuser quality of experience and suggests heuristics for optimising VTTP deployments.
Takelma Dissimilation and the Form of the OCP
Creators: name: Goodman, Beverly
Publisher: name: Zenodo
Year: 1992

description: In The Sound Pattern of English (SPE), Chomsky and Halle (1968) propose that
 the form of dissimilation rules is, in general, as in (1).
 (1) [aP] -> [-aP] ,_ [aP] (p. 178)
 Since dissimilation rules change the feature value [a F] to [-a F] in the context of [a F], it has been proposed that they are a result of the Obligatory Contour Principle (McCarthy 1985, Odden 1987, Yip 1988). McCarthy (1986) proposes that the OCP, in addition to applying to tonal sequences, also applies to melodic sequences as stated in (2). (2) Obligatory Contour Principle: At the melodic level, adjacent identical elements
 are prohibited (p. 208) In this paper I examine two rules of dissimilation in Takelma: Coronal Dissimilation and Nasal Dissimilation. These rules, I claim, are the result of the Obligatory Contour Principle (henceforth OCP). With respect to these two dissimilation rules the question arises as to whether the OCP functions only in cases of dissimilation or whether it plays a more general role in the grammar of Takelma. In addressing the question of the role of the OCP in Takeima, I focus on the non-symmetrical behavior of coronal sonorants and coronal obstruents. The coronal obstruents neither trigger nor undergo the dissimilation rule. One might suggest that this asymmetrical behavior can be characterized by the underspecification of the coronal feature in the case of obstruents. However, I will show that underspecification cannot account for the fact that Coronal Dissimilation targets only coronal sonorants. Rather, I argue that the OCP in Takelma is conditioned by a segment's value for sonorancy. I show that the dissimilation of coronal sonorants is part
 of a more general prohibition on adjacent coronal specifications with like values for the feature [sonorant] at both the underlying level and during phonological derivations.

description: The long-standing $4.2 \, σ$ muon $g-2$ anomaly may be the result of a new particle species which could also couple to dark matter and mediate its annihilations in the early universe. In models where both muons and dark matter carry equal charges under a $U(1)_{L_μ-L_τ}$ gauge symmetry, the corresponding $Z^\prime$ can both resolve the observed $g-2$ anomaly and yield an acceptable dark matter relic abundance, relying on annihilations which take place through the $Z^\prime$ resonance. Once the value of $(g-2)_μ$ and the dark matter abundance are each fixed, there is very little remaining freedom in this model, making it highly predictive. We provide a comprehensive analysis of this scenario, identifying a viable range of dark matter masses between approximately 10 and 100 MeV, which falls entirely within the projected sensitivity of several accelerator-based experiments, including NA62, NA64$μ$, $M^3$, and DUNE. Furthermore, portions of this mass range predict contributions to $ΔN_{\rm eff}$ which could ameliorate the tension between early and late time measurements of the Hubble constant, and which could be tested by Stage 4 CMB experiments.

description: Objective: To assess the experiences of hypoglycaemia in drivers with type 2 diabetes according to types of diabetes treatment; to determine experiences in different driving groups; and to ascertain if UK-based Driving and Vehicle Licensing Agency (DVLA) guidance concerning hypoglycaemia and driving is understood. Research, Design, and Methods: An online questionnaire was sent to UK drivers with type 2 diabetes between June−September 2014. Study limitations included selection bias inherent in online surveys, and lack of validation of the definition of hypoglycaemic symptoms by an expert patient group. Results: The survey was completed by 1569 (457 social, 590 commuters, and 522 business/work) drivers. Vocational drivers were more likely to be treated with an insulin secretagogue (sulphonylureas and glinides) (52%) than diet alone (18%), a non-insulin secretagogue (26%) or insulin (16%). Symptoms of hypoglycaemia (both mild and severe) were reported by 62% of the total cohort in the past year. Risk was greatest in those with poor diabetes self-management behaviour and those receiving an insulin secretagogue. Among the 1112 respondents commuting or driving for a living, 16.8% had poor, 49.6% average, and 33.6% good diabetes self-management. Poor self-management was more frequent among vocational drivers and those receiving insulin secretagogues. Following an hypoglycaemic episode, only 24% of insulin-secretagogue-treated drivers and 39% of insulin-treated drivers would discontinue driving for the DVLA-recommended 45 minutes. Insulin-treated drivers were best informed about diabetes and driving. Healthcare providers were the preferred source of information on driving and diabetes for 78% of drivers. Conclusion: Hypoglycaemia risk is highest among drivers with poor diabetes self-management, those commuting or driving for a living and those taking insulin secretagogues. There is an educational need for all drivers concerning driving and hypoglycaemia.

description: The launch of space based gravitational wave (GW) detectors (e.g. Laser Interferometry Space Antenna; LISA) and current and upcoming Pulsar Timing Arrays (PTAs) will extend the GW window to low frequencies, opening new investigations into dynamical processes involving massive black hole binaries (MBHBs) and their mergers across cosmic time. MBHBs are expected to be among the primary sources for the upcoming low frequency ($10^{-4}-10^{-1}$ Hz) window probed by LISA. It is important to investigate the expected MBH merger rates and associated signals, to determine how potential LISA events are affected by physics included in current models. To study this, we post-process the large population of MBHBs in the Illustris simulation to account for dynamical friction time delays associated with BH infall/inspiral. We show that merger delays associated with binary evolution have the potential to decrease the expected merger rates, with $M_{\rm{BH}} > 10^6 M_\odot$ MBHBs (the lowest mass in Illustris) decreasing from $\sim 3$ yr$^{-1}$ to $\sim 0.1 $yr$^{-1}$, and shifting the merger peak from z $\sim 2$ to $\sim 1.25$. During this time, we estimate that accretion grows the total merging mass by as much as 7x from the original mass. Importantly, however, dynamical friction associated delays (which shift the mergers toward lower-redshift and higher-masses) lead to a stronger signal/strain for the emitted GWs in the LISA band, increasing mean frequency from $10^{-3.1}$ to $10^{-3.4}-10^{-4.0}$ Hz, and mean strain from $10^{-17.2}$ to $10^{-16.3}-10^{-15.3}$. Finally, we show that after including a merger delay and associated $M_{\rm{BH}}$ growth, mergers still tend to lie on the typical $M_{\rm{BH}}-M_*$ relation, but with an increased likelihood of an undermassive black hole.

description: We have investigated the effect of Cu substitution in Eu2(Ir1-xCux)2O7 with the help of magnetic and transport property measurements. XPS measurement reveals that each Cu2+ converts Ir4+ to double amount of Ir5+ ions. The metal-insulator transition temperature (T_MI) is obtained around 120 K. In the insulating phase, at lower temperature below 50 K, the temperature dependent resistivity follows a power law dependence and the magnitude of the exponent increases with Cu concentrations. The temperature dependent thermopower is observed to follow the electrical resistivity down to 50 K, except for a sudden drop in thermopower at temperature below 50 K. We find negligible Hall voltage in the metallic regime of the samples but a sudden Hall voltage is developed below 50 K. We observe bifurcation in zero field cooled and field cooled (ZFC-FC) magnetization below irreversibility temperature, exchange bias and negative magnetoresistance at 3 K and the magnitude of all these properties increases with Cu concentrations. In the insulating region (below 6 K) there exists a linear specific heat and its coefficient decreases with Cu doping which indicates the reduction of spinon contribution with Cu doping.

description: This research explores the dynamics of emergency evacuations in the presence of social groups. The investigation was carried out in the context of the basic Social Force Model (SFM). We included attractive feelings between people belonging to the same social group, as proposed in Int. J. Mod. Phys. C 27(6),1-16. We focused on the escaping dynamics through an emergency exit and through a corridor. We confirmed the results appearing in Int. J. Mod. Phys. C 27(6),1-16 for a desired velocity of 4 m/s, but further extended the analysis on the emergency exit to the range 1-8 m/s. We noticed that the presence of groups worsens the evacuation performance. However, very strong feelings can improve the escaping time with respect to moderate feelings. We call this phenomenon "Closer-Is-Faster", in analogy to the "Faster-Is-Slower" effect. The presence of social groups also affects the dynamic within a corridor by introducing an additional slow-down in the moving crowd.

description: The 1971 Fortuin-Kasteleyn-Ginibre (FKG) inequality for two monotone functions on a distributive lattice is well known and has seen many applications in statistical mechanics and other fields of mathematics. In 2008 one of us (Sahi) conjectured an extended version of this inequality for all $n>2$ monotone functions on a distributive lattice. Here we prove the conjecture for two special cases: for monotone functions on the unit square in ${\mathbb R}^k$ whose upper level sets are $k$-dimensional rectangles, and, more significantly, for arbitrary monotone functions on the unit square in ${\mathbb R}^2$. The general case for ${\mathbb R}^k, k>2$ remains open.

description: We study the impact of gravitational waves originating from a first order phase transition on structure formation. To do so, we perform a second order perturbation analysis in the $1+3$ covariant framework and derive a wave equation in which second order, adiabatic density perturbations of the photon-baryon fluid are sourced by the gravitational wave energy density during radiation domination and on sub-horizon scales. The scale on which such waves affect the energy density perturbation spectrum is found to be proportional to the horizon size at the time of the phase transition times its inverse duration. Consequently, structure of the size of galaxies and bigger can only be affected in this way by relatively late phase transitions at $\ge 10^{6}\,\text{s}$. Using cosmic variance as a bound we derive limits on the strength $α$ and the relative duration $(β/H_*)^{-1}$ of phase transitions as functions of the time of their occurrence which results in a new exclusion region for the energy density in gravitational waves today. We find that the cosmic variance bound forbids only relative long lasting phase transitions, e.g. $β/H_*\lesssim 6.8$ for $t_*\approx 5\times10^{11}\,\text{s}$, which exhibit a substantial amount of supercooling $α>20$ to affect the matter power spectrum.

description: In a recent paper of Akhunzhanov and Shatskov the two-dimensional Dirichlet spectrum with respect to Euclidean norm was defined. We consider an analogous definition for arbitrary norms on $\mathbb{R}^2$ and prove that, for each such norm, the set of Dirichlet improvable pairs contains the set of badly approximable pairs, hence is hyperplane absolute winning. To prove this we make a careful study of some classical results in the geometry of numbers due to Chalk--Rogers and Mahler to establish a Hajós--Minkowski type result for the critical locus of a cylinder. As a corollary, using a recent result of the first named author with Mirzadeh, we conclude that for any norm on $\mathbb{R}^2$ the top of the Dirichlet spectrum is not an isolated point.
