description: Objective: To determine the impact of endobronchial coils on health-related quality-of-life (HRQoL). This paper utilizes trial data to identify the predictors of HRQoL in patients with severe emphysema, and subsequently estimates the impact of a new treatment on HRQoL (measured by utilities). These utility estimates are used to generate indicative long-term QALY estimates for a range of clinically plausible scenarios as a precursor to cost-effectiveness analyses. Methods: Patient level HRQoL data from RENEW and the National Emphysema Treatment Trial (NETT) were combined and mapped to generic EuroQol 5-dimension health utility questionnaire (EQ-5D) values using a published algorithm. Multilevel statistical models were developed using treatment, time, response, and baseline characteristics (EQ-5D, age, gender, FEV1, lung RV) to predict EQ-5D over time. Lifetime QALY estimates were generated using published survival data from NETT (assuming no impact of treatment on mortality) and four clinically plausible response profiles. Each response profile was combined with assumptions around treatment impact (constant or time varying). Results: After controlling for baseline characteristics, both treatment and response had a statistically significant impact (p < .001) on utility (+0.101 and +0.061, respectively). When combined with selected baseline characteristics and time, Coils and Standard of Care (SoC) generated more QALYs than SoC alone in all scenarios, with incremental lifetime benefit ranging from 0.29–0.55 QALYs. Conclusions: Coils and SoC resulted in statistically significant improvements in HRQoL compared to SoC alone in patients with severe emphysema.

description: Late-onset Alzheimer’s disease (AD) is a complex multifactorial disease. The greatest known risk factor for late-onset AD is the E4 allele of the apolipoprotein E (APOE), while increasing age is the greatest known non-genetic risk factor. The cell type-specific functions of neural stem cells (NSCs), in particular their stem cell plasticity, remain poorly explored in the context of AD pathology. Here, we describe a new model that employs late-onset AD patient-derived induced pluripotent stem cells (iPSCs) to generate NSCs and to examine the role played by APOE4 in the expression of aging markers such as sirtuin 1 (SIRT1) in comparison to healthy subjects carrying APOE3. The effect of aging was investigated by using iPSC-derived NSCs from old age subjects as healthy matched controls. Transcript and protein analysis revealed that genes were expressed differently in NSCs from late-onset AD patients, e.g., exhibiting reduced autophagy-related protein 7 (ATG7), phosphatase and tensin homolog (PTEN), and fibroblast growth factor 2 (FGF2). Since SIRT1 expression differed between APOE3 and APOE4 NSCs, the suppression of APOE function in NSCs also repressed the expression of SIRT1. However, the forced expression of APOE3 by plasmids did not recover differently expressed genes. The altered aging markers indicate decreased plasticity of NSCs. Our study provides a suitable in vitro model to investigate changes in human NSCs associated with aging, APOE4, and late-onset AD.
Trade-off between the tolerance of located and unlocated errors in nondegenerate quantum error-correcting codes

description: In a recent study [Rohde et al., quant-ph/0603130 (2006)] of several quantum error correcting protocols designed for tolerance against qubit loss, it was shown that these protocols have the undesirable effect of magnifying the effects of depolarization noise. This raises the question of which general properties of quantum error-correcting codes might explain such an apparent trade-off between tolerance to located and unlocated error types. We extend the counting argument behind the well-known quantum Hamming bound to derive a bound on the weights of combinations of located and unlocated errors which are correctable by nondegenerate quantum codes. Numerical results show that the bound gives an excellent prediction to which combinations of unlocated and located errors can be corrected with high probability by certain large degenerate codes. The numerical results are explained partly by showing that the generalized bound, like the original, is closely connected to the information-theoretic quantity the quantum coherent information. However, we also show that as a measure of the exact performance of quantum codes, our generalized Hamming bound is provably far from tight.

description: We introduce the feedforward neural network to attack the sign problem via the path optimization method. The variables of integration is complexified and the integration path is optimized in the complexified space by minimizing the cost function which reflects the seriousness of the sign problem. For the preparation and optimization of the integral path in multi-dimensional systems, we utilize the feedforward neural network. We examine the validity and usefulness of the method in the two-dimensional complex $λϕ^4$ theory at finite chemical potential as an example of the quantum field theory having the sign problem. We show that the average phase factor is significantly enhanced after the optimization and then we can safely perform the hybrid Monte-Carlo method.

description: Introduction: Abortion is a crucial sexual and reproductive right. However, the legal situation of pregnancy termination is rather heterogeneous across countries and regions. The political climate and cultural perception may result in abortion-related stigma. This mixed-methods systematic review protocol aims to detail the proposed methods for assessing the current state of research on abortion stigma in high-income countries from an abortion seeker, healthcare provider and public perspective. Methods and analysis: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols guideline, we conducted a systematic literature search of peer-reviewed studies from high-income countries in relevant electronic databases: PubMed, CINHAL, PsycINFO, LIVIVO and Cochrane Library. Qualitative, quantitative and mixed-method studies that measured or examined abortion-related stigma in abortion seekers, healthcare professionals and the general public will be included. Assessment of risk of bias, data synthesis and qualitative meta-aggregation will be carried out. Ethics and dissemination: The results of the systematic review will be submitted to peer-reviewed journals and presented at relevant conferences.
Topologies for finite words : compatibility with the cantor topology

Subjects: subject: 510

description: Infinite words are often considered as limits of finite words. As topological methods have been proved to be useful in the theory of ω-languages it seems to be providing to include finite and infinite words into one (topological) space. In most cases this results in a poor topological structure induced on the subspace of finite words. In the present paper we investigate the possibility to link topologies in the space of finite words with a topology in the space of infinite words via a natural mapping. A requirement in this linking of topologies consists in the compatibility of the topological properties (openness, closedness etc.) of images with preimages and vice versa. Here, we show that choosing for infinite words the natural topology of the CANTOR space and the δ-limit as linking mapping there are several natural topologies on the space of finite words compatible with the topology of the CANTOR space. It is interesting to observe that besides the well-known prefix topology there are at least two more whose origin is from language theory – centers and supercenters of languages. We show that several of these topologies on the space of finite words fit into a class of ℒ-topologies and exhibit their special properties w.r.t. to the compatibility with the CANTOR topology.

OTUs were identified by MiSeq sequencing of MFC anode 16S rRNA gene amplicons from three biological replicates of four different developmental conditions: S (solution), E (early biofilm), I (intermediate biofilm), M (mature biofilm). In the R vegan package, a Gower dissimilarity matrix was constructed with the metaMDS function from a sample-by-species matrix of OTU counts. The ordiplot, orditorp, and ordihull functions then were used to generate the NMDS plot. Similarity in relative abundance of genera is represented as spatial proximity within the two principal coordinates. Samples for S and E were clustered close enough together to obscure distinction of sample replicates. Figure S5.

description: Aims: The Raunkiær's system classifies vascular plants into life forms based on the position of renewal buds during periods unfavourable for plant growth. Despite the importance of Raunkiær's system for ecological research, a study exploring the diversity and distribution of life forms on a continental scale is missing. We aim to (i) map the diversity and distribution of life forms in European vegetation and (ii) test for effects of bioclimatic variables while controlling for habitat-specific responses. Location: Europe. Methods: We used data on life forms of 8883 species recorded in 546,501 vegetation plots of different habitats (forest, grassland, scrub and wetland). For each plot, we calculated: (i) the proportion of species of each life form and (ii) the richness and evenness of life forms. We mapped these plot-level metrics averaged across 50 km × 50 km grid cells and modelled their response to bioclimatic variables. Results: Hemicryptophytes were the most widespread life form, especially in the temperate zone of Central Europe. Conversely, therophyte and chamaephyte species were more common in the Mediterranean as well as in the dry temperate regions. Moreover, chamaephytes were also more common in the boreal and arctic zones. Higher proportions of phanerophytes were found in the Mediterranean. Overall, a higher richness of life forms was found at lower latitudes while evenness showed more spatially heterogeneous patterns. Habitat type was the main discriminator for most of the responses analysed, but several moisture-related predictors still showed a marked effect on the diversity of therophytes and chamaephytes. Conclusions: Our maps can be used as a tool for future biogeographic and macro-ecological research at a continental scale. Habitat type and bioclimatic conditions are key for regulating the diversity and distribution of plant life forms, with concomitant consequences for the response of functional diversity in European vegetation to global environmental changes.
Bulk characterization of topological crystalline insulators: stability under interactions and relations to symmetry enriched U(1) quantum spin liquids

description: Topological crystalline insulators (TCIs) are nontrivial quantum phases of matter protected by crystalline (and other) symmetries. They are originally predicted by band theories, so an important question is their stability under interactions. In this paper, by directly studying the physical bulk properties of several band-theory-based nontrivial TCIs that are conceptually interesting and/or experimentally feasible, we show they are stable under interactions. These TCIs include (1) a weak topological insulator, (2) a TCI with a mirror symmetry and its time-reversal symmetric generalizations, (3) a doubled topological insulator with a mirror symmetry, and (4) two TCIs with symmetry-enforced-gapless surfaces. We describe two complementary methods that allow us to determine the properties of the magnetic monopoles obtained by coupling these TCIs to a U(1) gauge field. These methods involve studying different types of surface states of these TCIs. Applying these methods to our examples, we find all of them have nontrivial monopoles, which proves their stability under interactions. Furthermore, we discuss two levels of relations between these TCIs and symmetry enriched U(1) quantum spin liquids (QSLs). First, these TCIs are directly related to U(1) QSLs with crystalline symmetries. Second, there is an interesting correspondence between U(1) QSLs with crystalline symmetries and U(1) QSLs with internal symmetries. In particular, the TCIs with symmetry-enforced-gapless surfaces are related to the "fractional topological paramagnets" introduced in Ref. 1 by Zou et al.

A characterization of round spheres in space forms

Subjects: subject: Differential Geometry (math.DG)

description: Let $\mathbb Q^{n+1}_c$ be the complete simply-connected $(n+1)$-dimensional space form of curvature $c$. In this paper we obtain a new characterization of geodesic spheres in $\mathbb Q^{n+1}_c$ in terms of the higher order mean curvatures. In particular, we prove that the geodesic sphere is the only complete bounded immersed hypersurface in $\mathbb Q^{n+1}_c,\;c\leq 0,$ with constant mean curvature and constant scalar curvature. The proof relies on the well known Omori-Yau maximum principle, a formula of Walter for the Laplacian of the $r$-th mean curvature of a hypersurface in a space form, and a classical inequality of Gårding for hyperbolic polynomials.

description: A supertube is a supersymmetric configuration in string theory which occurs when a pair of branes spontaneously polarizes and generates a new dipole charge extended along a closed curve. The dipole charge of a codimension-2 supertube is characterized by the U-duality monodromy as one goes around the supertube. For multiple codimension-2 supertubes, their monodromies do not commute in general. In this paper, we construct a supersymmetric solution of five-dimensional supergravity that describes two supertubes with such non-Abelian monodromies, in a certain perturbative expansion. In supergravity, the monodromies are realized as the multi-valuedness of the scalar fields, while in higher dimensions they correspond to non-geometric duality twists of the internal space. The supertubes in our solution carry NS5 and 5$_2^2$ dipole charges and exhibit the same monodromy structure as the SU(2) Seiberg-Witten geometry. The perturbative solution has $\mathrm{AdS}_2\times S^2$ asymptotics and vanishing four-dimensional angular momentum. We argue that this solution represents a microstate of four-dimensional black holes with a finite horizon and that it provides a clue for the gravity realization of a pure-Higgs branch state in the dual quiver quantum mechanics.

description: We make a theoretical prediction for the ratio of the dark energy to other components in the Universe based on the scenario of the sequestering mechanism which was recently proposed as one possible way to solve the cosmological constant problem. In order to evaluate the value of dark energy and the others, we assume a specific scale factor which describes the Big-Crunch scenario in the scalar-tensor theory. We specify the parameter region where the one can explain the observed dark energy-matter ratio.

description: Digital technology has radically disrupted the established ways of organising the film industry. However, digital initiatives such as marketing and distribution strategies involving social media and online distribution have also provided means through which filmmakers manage this environment. I investigate the role of the digital data involved, which I term Digital Engagement Metrics (DEMs), in market reconfiguration. Through exploratory, longitudinal case study of market construction for independent films, the thesis articulates the interdependent combination of attributes that co-constitute DEMs’ highly mobile, and multifaceted valuation capacities, and develops a conceptualisation of their role as a market device. I engage with the literature of translation, calculation, and the performativity and materiality of markets. I then develop an approach for tracing market activity to understand the interaction of networked agencies that shape the arrangement of economic transactions. My analysis is delivered in three empirical chapters, which provide rare data on the emergent digital practice of a film production company. I chart the progressive establishment of DEMs’ role in the hybridisation of established market attachment frameworks, and the instantiation of new modes of coordinating market actors. I conclude that the dynamic assembly, content and distributed architecture of market arrangements involving DEMs simultaneously shape the product and enable its calculation. In addition to extending the reach of market studies into a new empirical field, I make a number of contributions to the theoretical literature. My findings bring two coordinating kinds of performativity into focus. These are the creation of felicitous conditions required to mobilise DEMs as an organisational concept, and the digital materialisation of the audience both as the market, and as a qualified property of the market object. Reading DEMs through the market devices lens renders previously hidden modes of calculation visible, and this has implications for developing assemblage-oriented research in the creative industries.

description: A previous controversial discussion regarding the interpretation of Rydberg spectra of gaseous dimethylpiperazine (DMP) as showing the co-existence of a localized and delocalized mixed-valent DMP+ radical cation is revisited. Here we show by high-level quantum-chemical calculations that an apparent barrier separating localized and delocalized DMP+ minima in previous multi-reference configuration-interaction (MRCI) calculations and in some other previous computations were due to unphysical curve crossings of the reference wave functions. These discontinuities on the surface are removed in state-averaged MRCI calculations and with some other, orthogonal high-level approaches, which do not provide a barrier and thus no localized minimum. We then proceed to show that in the actually observed Rydberg state of neutral DMP the 3s-type Rydberg electron binds more strongly to a localized positive charge distribution, generating a localized DMP* Rydberg-state minimum, which is absent for the DMP+ cation. This work presents a case where interactions of a Rydberg electron with the underlying cationic core alter molecular structure in a fundamental way.

description: We present results for pseudoscalar decay constants of heavy-light mesons using both quenched and N_f = 2 dynamical fermion configurations. A variety of fermion actions is investigated : Wilson, nonperturbative clover, and fat-link clover. For heavy quarks the Fermilab formalism is applied. In the quenched approximation, results with the nonperturbatively improved clover action of the Alpha collaboration allow us to study the systematic error of the continuum extrapolation from the Wilson action. In addition, we use quenched configurations to explore the effects of fattening. The lessons from the quenched analyses are then applied to data with dynamical fermions, where both Wilson and fat-link clover actions have been used. This allows us to attempt a continuum extrapolation of the dynamical results.

description: Gas metallicity is a key quantity used to determine the physical conditions of gaseous clouds in a wide range of astronomical environments, including interstellar and intergalactic space. In particular, considerable effort in circumgalactic medium (CGM) studies focuses on metallicity measurements, because gas metallicity serves as a critical discriminator for whether the observed heavy ions in the CGM originate in chemically-enriched outflows or in more chemically-pristine gas accreted from the intergalactic medium. However, because the gas is ionized, a necessary first step in determining CGM metallicity is to constrain the ionization state of the gas which, in addition to gas density, depends on the ultraviolet background radiation field (UVB). While it is generally acknowledged that both the intensity and spectral slope of the UVB are uncertain, the impact of an uncertain spectral slope has not been properly addressed in the literature. This Letter shows that adopting a different spectral slope can result in an order of magnitude difference in the inferred CGM metallicity. Specifically, a harder UVB spectrum leads to a higher estimated gas metallicity for a given set of observed ionic column densities . Therefore, such systematic uncertainties must be folded into the error budget for metallicity estimates of ionized gas. An initial study shows that empirical diagnostics are available for discriminating between hard and soft ionizing spectra. Applying these diagnostics helps reduce the systematic uncertainties in CGM metallicity estimates.

description: The closure of schools due to COVID-19 disrupted learning routines of thousands of students, resulting in reported performance decreases, especially among lower-performing students. However, some studies on students’ performance within intelligent tutoring systems (ITS) also found significant performance increases for times of school closures as compared to before. However, little is known about students’ longitudinal performance trajectories within ITS. Accordingly, we evaluated longitudinal data from German students (n ≈ 2,700 students; n ≈ 5 million problems) enrolled in an ITS for learning mathematics from January 2017 until the end of May 2021 to investigate the effect of periods of school closures (first and second) on students’ performance within the ITS during, between, and after school closures. We observed significant performance increases for both lower- and higher-performing students during, between, and after COVID-19 related school closures. Importantly, these improvements were more pronounced for lower-performing students compared to higher-performing students. Together, these results suggest that ITS may have helped to maintain mathematics learning, particularly for lower-performing students during COVID-19 related school closures and that these beneficial effects persisted at least for the following months when schools opened again. As such, the use of ITS for learning mathematics seems an appropriate approach for distance learning during times of crisis.

description: Increasing demand and high prices of advanced catalysts motivate a constant search for novel active materials with reduced content of noble metals. The development of thin films and core-shell catalysts seem to be a promising strategy along this path. Using Density Functional Theory we have analyzed a number of surface properties of supported bimetallic thin films with composition A3B (where A = Pt, Pd, B = Cu, Ag, Au). We focus on surface segregation, dissolution stability and surface electronic structure. We also address the chemisorption properties of Pd3Au thin films supported by different substrates, by probing the surface reactivity with CO. We find a strong influence of the support in the case of mono- and bilayers, while the surface strain seems to be the predominant factor in determining the surface properties of supported trilayers and thicker films. In particular, we show that the studied properties of the supported trilayers can be predicted from the lattice mismatch between the overlayer and the support. Namely, if the strain dependence of the corresponding quantities for pure strained surfaces is known, the properties of strained supported trilayers can be reliably estimated. The obtained results can be used in the design of novel catalysts and predictions of the surface properties of supported ultrathin catalyst layers.

Continuous non-perturbative regularization of QED

Year: 1996
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We regularize in a continuous manner the path integral of QED by construction of a non-local version of its action by means of a regularized form of Dirac's $δ$ functions. Since the action and the measure are both invariant under the gauge group, this regularization scheme is intrinsically non-perturbative. Despite the fact that the non-local action converges formally to the local one as the cutoff goes to infinity, the regularized theory keeps trace of the non-locality through the appearance of a quadratic divergence in the transverse part of the polarization operator. This term which is uniquely defined by the choice of the cutoff functions can be removed by a redefinition of the regularized action. We notice that as for chiral fermions on the lattice, there is an obstruction to construct a continuous and non ambiguous regularization in four dimensions. With the help of the regularized equations of motion, we calculate the one particle irreducible functions which are known to be divergent by naive power counting at the one loop order.
