description: In this paper we analyze two different functional formulations of classical mechanics. In the first one the Jacobi fields are represented by bosonic variables and belong to the vector (or its dual) representation of the symplectic group. In the second formulation the Jacobi fields are given as condensates of Grassmannian variables belonging to the spinor representation of the metaplectic group. For both formulations we shall show that, differently from what happens in the case presented in paper no. (I), it is possible to endow the associated Hilbert space with a positive definite scalar product and to describe the dynamics via a Hermitian Hamiltonian. The drawback of this formulation is that higher forms do not appear automatically and that the description of chaotic systems may need a further extension of the Hilbert space.

description: Dynamics has been generalized to a noncommutative phase space. The noncommuting phase space is taken to be invariant under the quantum group $GL_{q,p}(2)$. The $q$-deformed differential calculus on the phase space is formulated and using this, both the Hamiltonian and Lagrangian forms of dynamics have been constructed. In contrast to earlier forms of $q$-dynamics, our formalism has the advantage of preserving the conventional symmetries such as rotational or Lorentz invariance.

description: Recently, it has been suggested that topological superconductivity and Majorana end states can be realized in a chain of magnetic impurities on the surface of an s-wave superconductor when the magnetic moments form a spin helix as a result of the RKKY interaction mediated by the superconducting substrate. Here, we investigate this scenario theoretically by developing a tight-binding Bogoliubov-de Gennes description starting from the Shiba bound states induced by the individual magnetic impurities. While the resulting model Hamiltonian has similarities with the Kitaev model for one-dimensional spinless p-wave superconductors, there are also important differences, most notably the long-range nature of hopping and pairing as well as the complex hopping amplitudes. We use both analytical and numerical approaches to explore the consequences of these differences for the phase diagram and the localization properties of the Majorana end states when the Shiba chain is in a topological superconducting phase.

description: This paper is devoted to adaptive signal denoising in the context of Graph Signal Processing (GSP) using Spectral Graph Wavelet Transform (SGWT). This issue is addressed \emph{via} a data-driven thresholding process in the transformed domain by optimizing the parameters in the sense of the Mean Square Error (MSE) using the Stein's Unbiased Risk Estimator (SURE). The SGWT considered is built upon a partition of unity making the transform semi-orthogonal so that the optimization can be performed in the transformed domain. However, since the SGWT is over-complete, the divergence term in the SURE needs to be computed in the context of correlated noise. Two thresholding strategies called coordinatewise and block thresholding process are investigated. For each of them, the SURE is derived for a whole family of elementary thresholding functions among which the soft threshold and the James-Stein threshold. This multi-scales analysis shows better performance than the most recent methods from the literature. That is illustrated numerically for a series of signals on different graphs.

description: Transgene expression level compared to that of two endogenous mRNA. Transgene expression level in populations of EndoC-βΗ2-TVA cells transduced with either RCANBP(A) RIP 3HAH2BYFP or pSERS RIP GFP-IRES-ZeoR (the same three populations as in Fig. 7) was analyzed through qRT-PCR. Transgene mRNA level is expressed as the cycle threshold (Ct). Cells transduced with pSERS RIP GFP-IRES-ZeoR were not exposed to zeocin (middle panel), except for one aliquot during 12 days before harvesting (right panel). The transgene expression level was compared to that of two endogenous mRNA, CYCLOPHILIN A and INSULIN, in the same transduced cells, also shown as Ct. These analyses were performed on long term transduced cells (> 50 days after transduction) and the data are the means and SD of results obtained on the three independent population for each retrovector, with each point of the qRT-PCR done in duplicate.

N=2 Wess-Zumino model on the d=2 Euclidean lattice

description: We examine the N=2 Wess-Zumino model defined on the $d=2$ Euclidean lattice in connection with a restoration of the Leibniz rule in the limit $a\to0$ in perturbatively finite theory. We are interested in the difference between the Wilson and Ginsparg-Wilson fermions and in the effects of extra interactions introduced by an analysis of Nicolai mapping. As for the Wilson fermion, it induces a linear divergence to individual tadpole diagrams in the limit $a\to0$, which is absent in the Ginsparg-Wilson fermion. This divergence suggests that a careful choice of lattice regularization is required in a reliable numerical simulation. As for the effects of the extra couplings introduced by an analysis of Nicolai mapping, the extra couplings do not completely remedy the supersymmetry breaking in correlation functions induced by the failure of the Leibniz rule in perturbation theory, though those couplings ensure the vanishing of vacuum energy arising from disconnected diagrams. Supersymmetry in correlation functions is recovered in the limit $a\to 0$ {\em with or without} those extra couplings. In the context of lattice theory, it may be properly said that supersymmetry does not improve ultraviolet properties but rather it is well accommodated in theories with good ultraviolet properties.

description: What methods do writers and illustrators use to visually approach the comic book page in an American Superhero form that can be adapted to create a professional and engaging Australian hero comic? The purpose of this research is to adapt the approaches used by prominent and influential writers and artists in the American superhero/action comic-book field to create an engaging Australian hero comic book. Further, the aim of this thesis is to bridge the gap between the lack of academic writing on the professional practice of the Australian comic industry. In order to achieve this, I explored and learned the methods these prominent and professional US writers and artists use. Compared to the American industry, the creating of comic books in Australia has rarely been documented, particularly in a formal capacity or from a contemporary perspective. The process I used was to navigate through the research and studio practice from the perspective of a solo artist with an interest to learn, and to develop into an artist with a firmer understanding of not only the medium being engaged, but the context in which the medium is being created. This means both in the American genre and its adaptation in Australia within the context of the local scene.

description: Stabilities and structures of β- and α-Sn nanoparticles are studied using density functional theory. Results show that β-Sn nanoparticles are more stable. For both phases of Sn, nanoparticles smaller than 1 nm (∼48 atoms) are amorphous and have a band gap between 0.4 and 0.7 eV. The formation of band gap is found to be due to amorphization. By increasing the size of Sn nanoparticles (1–2.4 nm), the degree of crystallization increases and the band gap decreases. In these cases, structures of the core of nanoparticles are bulk-like, but structures of surfaces on the faces undergo reconstruction. This study suggests a strong size dependence of electronic and atomic structures for Sn nanoparticle anodes in Li-ion batteries.

description: Using public cloud services for storing and sharing confidential data requires end users to cryptographically protect both the data and the access to the data. In some cases, the identity of end users needs to remain confidential against the cloud provider and fellow users accessing the data. As such, the underlying cryptographic access control mechanism needs to ensure the anonymity of both data producers and consumers. We introduce A-SKY, a cryptographic access control extension capable of providing confidentiality and anonymity guarantees, all while efficiently scaling to large organizations. A-SKY leverages trusted execution environments (TEEs) to address the impracticality of anonymous broadcast encryption (ANOBE) schemes, achieving faster execution times and shorter ciphertexts. The innovative design of A-SKY limits the usage of the TEE to the narrow set of data producing operations, and thus optimizes the dominant data consumption actions by not requiring a TEE. Furthermore, we propose a scalable implementation for A-SKY leveraging micro-services that preserves strong security guarantees while being able to efficiently manage realistic large user bases. Results highlight that the A-SKY cryptographic scheme is 3 orders of magnitude better than state of the art ANOBE, and an end-to-end system encapsulating A-SKY can elastically scale to support groups of 10 000 users while maintaining processing costs below 1 second.

description: People perceive out-groups, minorities, and novel groups more negatively than in-groups, majorities, and familiar groups. Previous research has argued that such intergroup biases may be caused by the order in which people typically encounter social groups (Alves et al., 2018; Sherman et al., 2009). Groups that are relatively novel to perceivers (e.g., outgroups, minorities) are primarily associated with distinct attributes that differentiate them from familiar groups. Because distinct attributes are typically negative, attitudes toward novel groups are negatively biased. Five experiments (Ntotal = 2,615 adults) confirm the generalizability of the novel groups’ disadvantage to different aspects of attitude formation (i.e., evaluations, memory, stereotyping), to cases with more than two groups, and to cases where groups are majorites/minority or in-groups/out-groups. Our findings reveal a remarkably robust influence of learning order in the formation of group attitudes, and they imply that people often perceive novel groups more negatively than they actually are.

description: Non-SIN α-retrovectors are not totally defective in mammalian cells. 293 T-TVA cells were transduced with the non-SIN α-retrovector RCAN CMV GFP-IRES-ZeoR and cultured 12 days in presence of zeocin. Then (that is 14 days and three passages after transduction), the conditioned medium (CM) of the 293 T-TVA RCANBP(A) CMV GFP-IRES-ZeoR cells were added to naive 293 T-TVA cells, which were next exposed to a zeocin-containing medium. 2 weeks later, the receiving cells were fixed and colored with crystal violet. Some zeocin-resistant foci can be observed (middle image). As a control, naive 293 T cells (not TVA) were subjected in parallel to the same CM exposure and zeocin selection. With these cells, no zeocin resistant foci were observed (bottom image) indicating that the transmission of zeocin resistance by the conditioned medium is dependent on TVA expression in the receiving cells. As a negative control, the conditioned medium of 293 T-TVA transduced with RCASBP(A) 3HAH2BYFP (devoid of ZeoR) was also tested under the same conditions on 293 T-TVA cells (upper image). This experiment was done once and its results were confirmed using the conditioned medium of RCASBP(A) GFP-IRES-ZeoR-transduced 293 T cells (not shown). (DOCX 119 kb)

description: Model-agnostic interpretation techniques allow us to explain the behavior of any predictive model. Due to different notations and terminology, it is difficult to see how they are related. A unified view on these methods has been missing. We present the generalized SIPA (sampling, intervention, prediction, aggregation) framework of work stages for model-agnostic interpretations and demonstrate how several prominent methods for feature effects can be embedded into the proposed framework. Furthermore, we extend the framework to feature importance computations by pointing out how variance-based and performance-based importance measures are based on the same work stages. The SIPA framework reduces the diverse set of model-agnostic techniques to a single methodology and establishes a common terminology to discuss them in future work.

description: We identify Melrose's suspended algebra of pseudodifferential operators with a subalgebra of the algebra of parametric pseudodifferential operators with parameter space $\R$. For a general algebra of parametric pseudodifferential operators, where the parameter space may now be a cone $Γ\subset\R^p$, we construct a unique ``symbol valued trace'', which extends the $L^2$-trace on operators of small order. This allows to construct various trace functionals in a systematic way. Furthermore we study the higher-dimensional eta-invariants on algebras with parameter space $\R^{2k-1}$. Using Clifford representations we construct for each first order elliptic differential operator a natural family of parametric pseudodifferential operators over $\R^{2k-1}$. The eta-invariant of this family coincides with the spectral eta-invariant of the operator.

description: We derive the details of a new screening mechanism where the interactions of baryons and dark matter can be screened according to the local dark matter density. In this mechanism, the value of Newton's constant is dark matter density-dependent, allowing for the possibility that astrophysical phenomena are very different in galaxies less dense than the Milky Way. The parameterized post Newtonian parameter $γ$, which quantifies the difference between kinematical and lensing probes, also depends on dark matter density. We calculate the effects of varying $G$ on various stages of stellar evolution, focusing on observables that impact cosmology: the Cepheid period--luminosity relation and the supernova Ia magnitude--redshift relation. Other potential tests of the model are also investigated including main-sequence, post-main sequence, and low mass dwarf stars. Finally, we discuss how extragalactic tests of $γ$ could provide complementary constraints.

description: We prove a general rigorous lower bound for $W(Λ,q)=\exp(S_0(Λ,q)/k_B)$, the exponent of the ground state entropy of the $q$-state Potts antiferromagnet, on an arbitrary Archimedean lattice $Λ$. We calculate large-$q$ series expansions for the exact $W_r(Λ,q)=q^{-1}W(Λ,q)$ and compare these with our lower bounds on this function on the various Archimedean lattices. It is shown that the lower bounds coincide with a number of terms in the large-$q$ expansions and hence serve not just as bounds but also as very good approximations to the respective exact functions $W_r(Λ,q)$ for large $q$ on the various lattices $Λ$. Plots of $W_r(Λ,q)$ are given, and the general dependence on lattice coordination number is noted. Lower bounds and series are also presented for the duals of Archimedean lattices. As part of the study, the chromatic number is determined for all Archimedean lattices and their duals. Finally, we report calculations of chromatic zeros for several lattices; these provide further support for our earlier conjecture that a sufficient condition for $W_r(Λ,q)$ to be analytic at $1/q=0$ is that $Λ$ is a regular lattice.

description: Advances in neuroscience uncover the mechanisms employed by the brain to efficiently solve complex learning tasks with very limited resources. However, the efficiency is often lost when one tries to port these findings to a silicon substrate, since brain-inspired algorithms often make extensive use of complex functions such as random number generators, that are expensive to compute on standard general purpose hardware. The prototype chip of the 2nd generation SpiNNaker system is designed to overcome this problem. Low-power ARM processors equipped with a random number generator and an exponential function accelerator enable the efficient execution of brain-inspired algorithms. We implement the recently introduced reward-based synaptic sampling model that employs structural plasticity to learn a function or task. The numerical simulation of the model requires to update the synapse variables in each time step including an explorative random term. To the best of our knowledge, this is the most complex synapse model implemented so far on the SpiNNaker system. By making efficient use of the hardware accelerators and numerical optimizations the computation time of one plasticity update is reduced by a factor of 2. This, combined with fitting the model into to the local SRAM, leads to 62% energy reduction compared to the case without accelerators and the use of external DRAM. The model implementation is integrated into the SpiNNaker software framework allowing for scalability onto larger systems. The hardware-software system presented in this work paves the way for power-efficient mobile and biomedical applications with biologically plausible brain-inspired algorithms.

description: Using a simplified version of the RG transformation of Dyson's hierarchical model, we show that one can calculate all the non-universal quantities entering into the scaling laws by combining an expansion about the high-temperature fixed point with a dual expansion about the critical point. The magnetic susceptibility is expressed in terms of two dual quantities transforming covariantly under the RG transformation and has a smooth limit in the high-temperature limit. Using the analogy with hamiltonian systems, the simplified example discussed here is similar to the anharmonic oscillator, while more realistic examples can be tought of as coupled oscillators allowing resonance phenomena.

description: We show that the requirement of manifest coordinate invariance of perturbatively defined quantum-mechanical path integrals in curved space leads to an extension of the theory of distributions by specifying unique rules for integrating products of distributions. The rules are derived using equations of motion and partial integration, while keeping track of certain minimal features stemming from the unique definition of all singular integrals in 1 - epsilon dimensions. Our rules guarantee complete agreement with much more cumbersome calculations in 1- epsilon dimensions where the limit epsilon --> 0 is taken at the end. In contrast to our previous papers where we solved the same problem for an infinite time interval or zero temperature, we consider here the more involved case of finite-time (or non-zero temperature) amplitudes.

A 293 T-TVA cells were transduced with the indicated α-retrovectors and cultured in presence of zeocin. The three retrovectors harbor ZeoR 3′ to an IRES sequence (GFP-IRES-ZeoR). After selection, cells were analyzed for GFP fluorescence intensity by flow cytometry. 293 T-TVA cells transduced with RCANBP(A) RIP GFP-IRES-ZeoR are extremely dimly fluorescent compared to the two other populations. MFI: Mean of Fluorescence Intensity. All the analyzed cells were taken into account to determine the MFI for each population, including the negative cells in RCANBP(A) RIP GFP-IRES-ZeoR-transduced 293 T-TVA cells. This experiment was done twice, which gave concordant results. B. The same three transduced 293 T-TVA cells populations (left image, right column) as well as three other populations transduced in parallel with the corresponding non-IRES containing retrovectors (left image, left column) were cultured in presence of zeocin for 7 days, then fixed and colored with crystal violet. While RCANBP(A) RIP GFP-IRES-ZeoR confers zeocin-resistance, RCAN RIP ZeoR does not. Similar observations were made in DF1 chicken fibroblasts producing the tested supernatants (middle image). In contrast, the same supernatants are equally efficient to confer zeocin resistance to MIN6-TVA β (right image). The repartition of the six populations for each six-well plate is the same, and indicated below the images. This experiment was done twice, which gave concordant results. (DOCX 172 kb)

description: In large-scale computation of physics problems, one often encounters the problem of determining a multi-dimensional function, which can be time-consuming when computing each point in this multi-dimensional space is already time-demanding. In the work, we propose that the active learning algorithm can speed up such calculations. The basic idea is to fit a multi-dimensional function by neural networks, and the key point is to make the query of labeled data economically by using a stratagem called "query by committee". We present the general protocol of this fitting scheme, as well as the procedure of how to further compute physical observables with the fitted functions. We show that this method can work well with two examples, which are quantum three-body problem in atomic physics and the anomalous Hall conductivity in condensed matter physics, respectively. In these examples, we show that one reaches an accuracy of few percent error for computing physical observables with less than $10\%$ of total data points compared with uniform sampling. With these two examples, we also visualize that by using the active learning algorithm, the required data are added mostly in the regime where the function varies most rapidly, which explains the mechanism for the efficiency of the algorithm. We expect broad applications of our method on various kind of computational physics problems.

description: Medical practice entails lifelong learning of both the science and art of medicine. However, it is not easy to teach or observe what one has learned about the latter. Previous literature has found that learning during the clinical phase is influenced by both the macro, structural issues and micro, individual factors. This ethnographic study investigates the deliberate, systematic, and sustained effort of clinical education at a district hospital in Taiwan in order to find out how medical educators can train and retain caring and competent physicians. It focuses on the students’ experiences during their clerkship, formal and informal teachings such as ward rounds, teachings at the operating room, and fortnightly medical humanities discussions, as well as what the hospital has done to create a conducive environment for teaching and learning. Using a grounded theory approach, it uncovers the problems novices face in clinical practice and learning and effective techniques expert clinicians use in teaching. It concludes that the most effective and efficient education happens when learning is made explicit and visible, when teachers actively engage students in legitimate peripheral participation, when learners become self-directed in their endeavors, and when there is a community of reflective practitioners.

description: The characterizing feature of a many-body localized phase is the existence of an extensive set of quasi-local conserved quantities with an exponentially localized support. This structure endows the system with the signature logarithmic in time entanglement growth between spatial partitions. This feature differentiates the phase from Anderson localization, in a non-interacting model. Experimentally measuring the entanglement between large partitions of an interacting many-body system requires highly non-local measurements which are currently beyond the reach of experimental technology. In this work we demonstrate that the defining structure of many-body localization can be detected by the dynamics of a simple quantity from quantum information known as the total correlations which is connected to the local entropies. Central to our finding is the necessity to propagate specific initial states, drawn from the Hamiltonian unbiased basis (HUB). The dynamics of the local entropies and total correlations requires only local measurements in space and therefore is potentially experimentally accessible in a range of platforms.

description: Jacobi brackets (a generalization of standard Poisson brackets in which Leibniz's rule is replaced by a weaker condition) are extended to brackets involving an arbitrary (even) number of functions. This new structure includes, as a particular case, the recently introduced generalized Poisson structures. The linear case on simple group manifolds is also studied and non-trivial examples (different from those coming from generalized Poisson structures) of this new construction are found by using the cohomology ring of the given group.

description: The EU has concluded the Association Agreements (AAs) with Georgia, Moldova and Ukraine. These are very ambitious, complex and comprehensive legal treaties. The AAs have a dual purpose: to enable political cooperation and economic integration with the EU and promote modernization of the partner countries. The key instrument in achieving these goals is the ‘export of the acquis’: the partner countries have taken on extensive, binding commitments to adopt the vast sways of the acquis. In this paper, however, we argue that the transformative role of the acquis on its own have not been tested and hence should not be overstated ex ante. In our view, for the AAs to achieve their objectives, it is imperative to recognise this underlying challenge and develop strategies to address the fundamental ‘commitment-capacity gap’ in the partner countries. Against this backdrop, we investigate to what extent EU’s strategy focuses on the narrowly defined legal approximation versus broader support for strengthening state capacity. In the empirical part of the paper we examine specific measures adopted to close the ‘commitment-capacity’ gap of the partner country. Our analyses indicate that only in the case of Ukraine have some deliberate, pro-active adaptations taken place. The dramatic events of 2014 and Russia’s punitive measures against Ukraine prompted the EU to provide more tailored and flexible assistance to ensure support for institutional reforms, as a precondition for legal approximation. In Moldova, the EU has confronted the fundamental weakness of the state only as a result of the 2014 banking scandal. In Georgia, it seems that the EU is conducting ‘business as usual’, although there is some early evidence that it has started to take into account the developmental needs of the partner country. The limited appreciation of the challenges and resulting adaptions so far has implications in terms of the implementation of the AA and, more importantly, the actual transformative power of the EU in the Eastern neighbourhood.

description: I show that there exist universal constants $C(r) < \infty$ such that, for all loopless graphs $G$ of maximum degree $\le r$, the zeros (real or complex) of the chromatic polynomial $P_G(q)$ lie in the disc $|q| < C(r)$. Furthermore, $C(r) \le 7.963906... r$. This result is a corollary of a more general result on the zeros of the Potts-model partition function $Z_G(q, {v_e})$ in the complex antiferromagnetic regime $|1 + v_e| \le 1$. The proof is based on a transformation of the Whitney-Tutte-Fortuin-Kasteleyn representation of $Z_G(q, {v_e})$ to a polymer gas, followed by verification of the Dobrushin-Kotecký-Preiss condition for nonvanishing of a polymer-model partition function. I also show that, for all loopless graphs $G$ of second-largest degree $\le r$, the zeros of $P_G(q)$ lie in the disc $|q| < C(r) + 1$. Along the way, I give a simple proof of a generalized (multivariate) Brown-Colbourn conjecture on the zeros of the reliability polynomial for the special case of series-parallel graphs.

description: Abnormal ubiquitous localization of 3HAH2BYFP in 293 T cells transduced with RCANBP(A) RIP 3HAH2BYFP. Some foci of fluorescent cells can be found in 293 T cells transduced with RCANBP(A) RIP 3HAH2BYFP. Cells within these foci often display an evenly distributed fluorescence, i.e. detectable in both the cytosol and the nucleus of the cells (left panel, upper image). In contrast, β cells (EndoC-βΗ2 or MIN6-TVA) transduced with the same retrovector display the expected nuclear fluorescence (left panel, middle and bottom images) while the same transgene in RCANBP(A) CMV-transduced 293 T also gives a strictly nuclear signal (right image).

description: It is shown that the standard formulation of quantum mechanics in terms of Hermitian Hamiltonians is overly restrictive. A consistent physical theory of quantum mechanics can be built on a complex Hamiltonian that is not Hermitian but satisfies the less restrictive and more physical condition of space-time reflection symmetry (PT symmetry). Thus, there are infinitely many new Hamiltonians that one can construct to explain experimental data. One might expect that a quantum theory based on a non-Hermitian Hamiltonian would violate unitarity. However, if PT symmetry is not spontaneously broken, it is possible to construct a previously unnoticed physical symmetry C of the Hamiltonian. Using C, an inner product is constructed whose associated norm is positive definite. This construction is completely general and works for any PT-symmetric Hamiltonian. Observables exhibit CPT symmetry, and the dynamics is governed by unitary time evolution. This work is not in conflict with conventional quantum mechanics but is rather a complex generalisation of it.

description: By exploiting the relation between Fredholm modules and the Segal-Shale-Stinespring version of canonical quantization, and taking as starting point the first-quantized fields described by Connes' axioms for noncommutative spin geometries, a Hamiltonian framework for fermion quantum fields over noncommutative manifolds is introduced. We analyze the ultraviolet behaviour of second-quantized fields over noncommutative 3-tori, and discuss what behaviour should be expected on other noncommutative spin manifolds.

description: Accretion disks around supermassive black holes are promising sites for stellar mass black hole mergers detectable with LIGO. Here we present the results of Monte-Carlo simulations of black hole mergers within 1-d AGN disk models. For the spin distribution in the disk bulk, key findings are: (1) The distribution of $χ_{\rm eff}$ is naturally centered around $\tildeχ_{\rm eff} \approx 0.0$, (2) the width of the $χ_{\rm eff}$ distribution is narrow for low natal spins. For the mass distribution in the disk bulk, key findings are: (3) mass ratios $\tilde{q} \sim 0.5-0.7$, (4) the maximum merger mass in the bulk is $\sim 100-200M_{\odot}$, (5) $\sim 1\%$ of bulk mergers involve BH $>50M_{\odot}$ with (6) $\simeq 80\%$ of bulk mergers are pairs of 1st generation BH. Additionally, mergers at a migration trap grow an IMBH with typical merger mass ratios $\tilde{q}\sim 0.1$. Ongoing LIGO non-detections of black holes $>10^{2}M_{\odot}$ puts strong limits on the presence of migration traps in AGN disks (and therefore AGN disk density and structure) as well as median AGN disk lifetime. The highest merger rate occurs for this channel if AGN disks are relatively short-lived ($\leq 1$Myr) so multiple AGN episodes can happen per Galactic nucleus in a Hubble time.
