description: Controlling the degradation rates of polymers is crucial for their application in tissue engineering or to achieve degradation of the polymers in the wastewater purification. As hydrophobic polyesters often exhibit very slow degradation rates, we report here increased biodegradation rates of poly(globalide-co-ε-caprolactone) copolymers (PGlCL) produced by enzymatic ring-opening copolymerization and post-functionalized with N-acetylcysteine by thiol-ene reaction. The degradation rates of the PGlCL and post-modified PGlCL-NAC films were determined by weight-loss experiments. The polymer films were immersed in phosphate-buffered saline (PBS) solution, and PBS containing lipase from Pseudomonas cepacia. The degree of functionalization affected the degradation behavior, and samples with a higher degree of functionalization presented higher weight loss. Finally, a degradation assay was performed in activated sludge, and PGlCL-NAC presented high degradability, having a degradation behavior similar to starch. Density Functional Theory (DFT) calculations were used to assess the changes in chemical properties and electronic charge distribution of PGlCL after its functionalization with NAC, helping to understand its influence in their degradability. The results obtained confirm the possibility to increase the degradation rates of copolyesters based on caprolactone and globalide by thiol-ene post-functionalization, being a promising alternative for applications in biomedicine or the packaging sector.

description: This is the first of two papers on the superselection sectors of the conformal model in the title, in a time zero formulation. A classification of the sectors of the net of observables as restrictions of solitonic (twisted) and non-solitonic (untwisted) sector automorphisms of proper extensions of the observable net is given. All of them are implemented by the elements of a field net in a non-regular vacuum representation and the existence of a global compact Abelian gauge group is proved. A non-trivial center in the fixed-point net of this gauge group appears, but in an unphysical representation and reducing to the identity in the physical one. The completeness of the described superselection structure, to which the second paper is devoted, is shown in terms of Roberts' net cohomology. Some general features of physical field models defined by twisted cross products of Weyl algebras in non-regular representations are also presented.

Swipe Left to Pray. Analyzing Authority and Transcendence in Prayer Apps
Creators: name: Karis, Tim
Publisher: name: Entangled Religions
Year: 2020

description: This paper centers on a fairly new phenomenon in digital religion: prayer apps. After an overview of their typical features, the paper will present a number of analytical perspectives on such apps, arguing that investing in theoretical work is needed, particularly in a young research field. Starting points are provided by Heidi Campbell’s four-layer model of religious authority, Michel Foucault’s concept of “technologies of the self,” Birgit Meyer’s understanding of religion as a practice of mediation, and by the conceptualization of the transcendence/immanence distinction developed at the Käte Hamburger Kolleg Dynamics of the History of Religions Between Asia and Europe at the Center for Religious Studies, Ruhr-Universät Bochum. With regards to authority, it will be pointed out that prayer apps employ highly different strategies of authorization. These include the evocation of traditional authority, building trust through the use of familiar design language (often borrowed from outside the religious field), and self-imposed strategies aimed at the ‘improvement’ of the individual believer. As for the transcendence/immanence-distinction, it will be argued that it is important to differentiate between prayer apps that have a more auxiliary character, helping users to prepare their offline praying practice, and those apps that allow users to pray directly on their phone – which has significant implications for the understanding of transcendence.

description: Objective: We aimed to investigate potential causes of higher risk of treatment interruptions within the multicountry Strategic Timing of AntiRetroviral Treatment (START) trial in 2015. Methods: We defined baseline as the date of starting antiretroviral therapy (ART) and a treatment interruption as discontinuing ART for at least 2 weeks. Participants were stratified by randomization arm and followed from baseline to earliest end date of the initial phase of START, death, date of consent withdrawn or date of first treatment interruption. Cox regression was used to calculate hazard ratios and 95% confidence intervals for factors that may predict treatment interruptions in each arm. Results: Of the 3438 participants who started ART, 2286 were in the immediate arm and 1152 in the deferred arm. 12.9% of people in the immediate arm and 10.5% of people in the deferred arm experienced at least one treatment interruption by 3 years after starting ART. In adjusted analyses, age [hazard ratio for 35–50 years: 0.75 (95% confidence interval: 0.59–0.97) and >50 years: 0.53 (0.33–0.80) vs. <35 years], education status [hazard ratio for postgraduate education vs. less than high-school education (0.23 (0.10–0.50))] and region [hazard ratio for United States vs. Europe/Israel (3.16 (2.09–4.77))] were significantly associated with treatment interruptions in the immediate arm. In the deferred arm, age and education status were significantly associated with treatment interruptions. Conclusion: Within START, we identified younger age and lower educational attainment as potential causes of ART interruption. There is a need to strengthen adherence advice and wider social support in younger people and those of lower education status.

description: The problem of the harmonic oscillator with a centrally located delta function potential can be exactly solved in one dimension where the eigenfunctions are expressed as superpositions of the Hermite polynomials or as confluent hypergeometric functions in general. The eigenfunctions obtained exactly are difficult to visualise and hence to gain more insight, one can attempt using model wave functions which are explicitly and simply expressed. Here we apply the variational method to verify how close one can approach the exact ground state eigenvalues using such trial wave functions. We obtain the estimates of the ground state energies which are closer to the exact values in comparison to earlier approximate results for both the repulsive and attractive delta potentials.

description: Principled methods with which to appropriately analyze missing data have long existed; however, broad implementation of these methods remains challenging. In this and 2 companion papers (Am J Epidemiol. 2018;187(3):576–584 and Am J Epidemiol. 2018;187(3):585–591), we discuss issues pertaining to missing data in the epidemiologic literature. We provide details regarding missing-data mechanisms and nomenclature and encourage the conduct of principled analyses through a detailed comparison of multiple imputation and inverse probability weighting. Data from the Collaborative Perinatal Project, a multisite US study conducted from 1959 to 1974, are used to create a masked data-analytical challenge with missing data induced by known mechanisms. We illustrate the deleterious effects of missing data with naive methods and show how principled methods can sometimes mitigate such effects. For example, when data were missing at random, naive methods showed a spurious protective effect of smoking on the risk of spontaneous abortion (odds ratio (OR) = 0.43, 95% confidence interval (CI): 0.19, 0.93), while implementation of principled methods multiple imputation (OR = 1.30, 95% CI: 0.95, 1.77) or augmented inverse probability weighting (OR = 1.40, 95% CI: 1.00, 1.97) provided estimates closer to the “true” full-data effect (OR = 1.31, 95% CI: 1.05, 1.64). We call for greater acknowledgement of and attention to missing data and for the broad use of principled missing-data methods in epidemiologic research.

description: We present a class of quantum dimer models on the kagome lattice with full translational invariance that feature a quantum many-body scar state of analytically known entanglement properties within their spectra. Using exact diagonalization on lattices of up to 60 sites, we show that non-scar states conform to the eigenstate thermalization hypothesis. Specifically, we show that energies are distributed according to the Gaussian ensemble expected of their respective symmetry sector, illustrate the existence of the scar from bipartite entanglement properties, and demonstrate revival phenomena in studies of fidelity dynamics.

description: Analysis on the Binary Marginal Characteristics of Chinese Bamboo and Rattan Products Export [Objectives] To analyze the changes of export binary margins of Chinese bamboo rattan products, so as to clarify its export model, and further promote the healthy development growth of Chinese bamboo rattan products export.[Methods] Based on the export trade data of bamboo and rattan products from 2008 to 2018 in UN Comtrade database, the binary marginal decomposition method was employed to analyze the export growth pattern of bamboo and rattan products between China and 22 major trading partners.[Results] This paper shows that the export growth pattern of bamboo and rattan products between China and the target countries during the investigation period was dominated by extensive margin, supplemented by intensive margin, indicating that the export growth of Bamboo and rattan products is mainly driven by the increase of export types of bamboo and rattan products, and the potential of export intensive margin needs to be further explored. [Conclusions] It is necessary to continuously increase export type of bamboo rattan products, build an information platform for bamboo rattan trade, and strengthen the ability of dealing with trade barriers, and strengthening technology innovation of bamboo and rattan industry, so as to improve added value of bamboo and rattan products, and form an intensive model of export growth of bamboo rattan products.

description: This paper examines whether there is a premium in country size. We study whether there are significant gains from being a small or a large country in terms of certain socioeconomic indicators and how large this premium is. Using panel data for 200 countries over 50 years, we estimate premia for various sizes of nations across a variety of key economic and socioeconomic performance indicators. We find that smaller countries are richer, have larger governments, and are more prudent in terms of fiscal policies than larger ones. On the other hand, smaller countries seem to be subject to higher absolute and per capita costs for the provision of essential public goods, which may lower their socioeconomic performance in terms of health and education. In terms of economic performance, small countries seem to do better than large countries, compensating for smallness by relying on foreign trade and foreign direct investment. The latter comes at the cost of higher vulnerability to external shocks, resulting in higher volatility of growth rates. This paper's findings offer essential guidance to policymakers, international organizations, and business researchers, especially those assessing a country's economic or socioeconomic performance or potential. The study implies that comparisons with medium-sized or large countries may be of little utility in predicting the performance of small countries.

description: Background: HIV-infected individuals transitioning from incarceration to the community are at risk for loss of viral suppression. We compared the effects of imPACT, a multidimensional intervention to promote care engagement after release, to standard care on sustaining viral suppression after community re-entry. Methods: This trial randomized 405 HIV-infected inmates being released from prisons in Texas and North Carolina with HIV-1 RNA levels <400 copies/mL to imPACT versus standard care. The imPACT arm received motivational interviewing prerelease and postrelease, referral to care within 5 days of release, and a cellphone for medication text reminders. The standard care arm received routine discharge planning and a cellphone for study staff contact. The primary outcome was the difference between arms in week 24 postrelease viral suppression (HIV-1 RNA <50 copies/mL) using intention-to-treat analysis with multiple imputation of missing data. Results: The proportion with 24-week HIV-1 RNA <50 copies/mL was 60% and 61% in the imPACT and standard care arms, respectively [odds ratio for suppression 0.95 (95% confidence interval: 0.59 to 1.53)]. By week 6 postrelease, 86% in the imPACT arm versus 75% in the standard care arm attended at least 1 nonemergency clinic visit (P = 0.02). At week 24, 62% in both arms reported not missing any antiretroviral doses in the past 30 days (P > 0.99). Conclusions: Higher rates of HIV suppression and medical care engagement than expected based on previous literature were observed among HIV-infected patients with suppressed viremia released from prison. Randomization to a comprehensive intervention to motivate and facilitate HIV care access after prison release did not prevent loss of viral suppression. A better understanding of the factors influencing prison releasees' linkage to community care, medication adherence, and maintenance of viral suppression is needed to inform policy and other strategic approaches to HIV prevention and treatment.

description: It is proposed that the upper pseudogap phase (UPP) observed in the high-Tc cuprates correspond to the formation of spin singlet pairing under the bosonic resonating-valence-bond (RVB) description. We present a series of evidence in support of such a scenario based on the calculated magnetic properties including uniform spin susceptibility, spin-lattice and spin-echo relaxation rates, which consistently show that strong spin correlations start to develop upon entering the UPP, being enhanced around the momentum (π, π) while suppressed around (0, 0). The phase diagram in the parameter space of doping concentration, temperature, and external magnetic field, is obtained based on the the bosonic RVB theory. In particular, the competition between the Zeeman splitting and singlet pairing determines a simple relation between the "critical" magnetic field, H_{PG}, and characteristic temperature scale, T0, of the UPP. We also discuss the magnetic behavior in the lower pseudogap phase at a temperature Tv lower than T0, which is characterized by the formation of Cooper pair amplitude where the low-lying spin fluctuations get suppressed at both (0, 0) and (π, π). Properties of the UPP involving charge channels will be also briefly discussed.

The near-infrared spectrum of Mrk 1239: direct evidence of the dusty torus?

Subjects: subject: Astrophysics (astro-ph)

description: We report 0.8-4.5 micron SpeX spectroscopy of the narrow-line Seyfert 1 galaxy Mrk1239. The spectrum is outstanding because the nuclear continuum emission in the near-infrared is dominated by a strong bump of emission peaking at 2.2 micron, with a strength not reported before in an AGN. A comparison of the Mrk1239 spectrum to that of Ark564 allowed us to conclude that the continuum is strongly reddened by E(B-V)=0.54. The excess of emission, confirmed by aperture photometry and additional NIR spectroscopy, follows a simple blackbody curve at T=1200 K. This suggest that we may be observing direct evidence of dust heated near to the sublimation temperature, likely produced by the putative torus of the unification model. Although other alternatives are also plausible, the lack of star formation, the strong polarization and low extinction derived for the emission lines support the scenario where the hot dust is located between the narrow line region and the broad line region.

description: Polymer conductors that are solution-processable provide an opportunity to realize low-cost organic electronics. However, coating sequential layers can be hindered by poor surface wetting or dissolution of underlying layers. This has led to the use of transfer printing where solid film inks are transferred from a donor substrate to partially fabricated devices using a stamp. This approach typically requires favorable adhesion differences between the stamp, ink, and receiving substrate. Here, we present a shear-assisted organic printing (SHARP) technique that employs a shear load on a post-less polydimethylsiloxane (PDMS) elastomer stamp to print large-area polymer films that can overcome large unfavorable adhesion differences between the stamp and receiving substrate. We explore the limits of this process by transfer printing poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) films with varied formulation that tune the adhesive fracture energy. Using this platform, we show that the SHARP process is able to overcome a 10-fold unfavorable adhesion differential without the use of a patterned PDMS stamp, enabling large-area printing. The SHARP approach is then used to print PEDOT:PSS films in the fabrication of high-performance semitransparent organic solar cells.

description: The idea of using machine learning (ML) methods to reconstruct the dynamics of a system is the topic of recent studies in the geosciences, in which the key output is a surrogate model meant to emulate the dynamical model. In order to treat sparse and noisy observations in a rigorous way, ML can be combined to data assimilation (DA). This yields a class of iterative methods in which, at each iteration a DA step assimilates the observations, and alternates with a ML step to learn the underlying dynamics of the DA analysis. In this article, we propose to use this method to correct the error of an existent, knowledge-based model. In practice, the resulting surrogate model is an hybrid model between the original (knowledge-based) model and the ML model. We demonstrate numerically the feasibility of the method using a two-layer, two-dimensional quasi-geostrophic channel model. Model error is introduced by the means of perturbed parameters. The DA step is performed using the strong-constraint 4D-Var algorithm, while the ML step is performed using deep learning tools. The ML models are able to learn a substantial part of the model error and the resulting hybrid surrogate models produce better short- to mid-range forecasts. Furthermore, using the hybrid surrogate models for DA yields a significantly better analysis than using the original model.

description: Data independent acquisition (DIA) has emerged as an alternative to standard shotgun proteomics data-dependent acquisition methods (DDA) methods for quantitative experiments. DIA collects spectral
information without the need for a data dependent ion selection. This improves the chances of acquiring
MS/MS data even for peptides with low intensity MS1 peaks. We have implemented workflows for DIA analysis using EncyclopeDIA on our local University Galaxy-P website. We have tested three published datasets - yeast (Searle et al 2020); Plasmodium (Searle et al 2020) and HeLa cells (Searle et al 2018) and one unpublished IPRG Study 2020 DIA dataset (Weintraub Lab, University of Texas). We tested these datasets by using Protein FASTA file, six GPF files and experimental files as inputs. We also ran Standard EncyclopeDIA workflows while using spectral libraries (either predicted or experimental) which showed an improved identification and quantification statistics.

description: Similarity solutions to the nonlinear non-equilibrium Marshak wave problem with a time dependent radiation driving source are presented. The radiation transfer model used is the gray, non-equilibrium diffusion approximation in the supersonic regime. These solutions constitute an extension of existing non-equilibrium supersonic Marshak wave solutions which are linear, to the nonlinear regime, which prevails in realistic high energy density systems. The generalized solutions assume a material model with power law temperature dependent opacities and a material energy density which is proportional to the radiation energy density, as well as a surface radiation temperature drive which obeys a temporal power-law. The solutions are analyzed in detail and it is shown that they take various qualitatively different forms according to the values of the opacity exponents. The solutions are used to construct a set of standardized benchmarks for supersonic non-equilibrium radiative heat transfer, which are nontrivial but straightforward to implement. These solutions are compared in detail to implicit Monte-Carlo and discrete-ordinate transport simulations as well gray diffusion simulations, showing a good agreement, which demonstrates the usefulness of these solutions as a code verification test problem.

description: We consider the infinite directed graph with vertices the set of integers ...,-2,-1,0,1,2,... . Let v be a random variable taking either finite values or value "minus infinity". Consider random weights v(j,k), indexed by pairs (j,k) of integers with j0)>0, the conditional distribution of v, given v>0, is not degenerate, and that E exp(Cv) is finite, for some C>0. We derive local limit theorems in the normal and moderate large deviations regimes in the case where v has an arithmetic distribution. We also derive an integro-local theorem in the case where v has a non-lattice distribution.

description: Although marketing principles and strategies are taught in all major agribusiness management programs in the country, few agribusiness student groups use these very principles in the planning of their own activities. This article describes a market research project developed by the AgriBusiness Association at Colorado State University (CSU) as an example of how to integrate coursework with an undergraduate agribusiness organization's program of activities. In addition to reinforcing marketing principles learned at CSU, the project taught students the importance of setting objectives, research design, and data analysis. Many of the findings were used to plan and improve the club.

description: The effect of a magnetic field on the equilibrium spectral and transport properties of a single-molecule junction is studied using the numerical renormalization group method. The molecule is described by the Anderson-Holstein model in which a single vibrational mode is coupled to the electron density. The effect of an applied magnetic field on the conductance in the Kondo regime is qualitatively different in the weak and strong electron-phonon coupling regimes. In the former case, the Kondo resonance is split and the conductance is strongly suppressed by a magnetic field $g mu_B B \gtrsim k_BT_K$, with $T_K$ the Kondo temperature. In the strong electron-phonon coupling regime a charge analog of the Kondo effect develops. In this case the Kondo resonance is not split by the field and the conductance in the Kondo regime is enhanced in a broad range of values of $B$.

description: Study abroad provides students with a cross-cultural experience and a new perspective on the global marketplace. Seven students from the University of Georgia enrolled in the first agribusiness study-abroad course, entitled "International Agribusiness Marketing and Management: Focus on Mexico," at the Universidad Veracruzana in Xalapa during the Maymester 2000. Their curriculum included field trips to agribusinesses, Spanish classes and lectures on Mexican business culture, and NAFTA. As a result, students became more comfortable in cross-cultural environments and more confident in their academic and professional abilities.

description: In order to meet the requirements for performance, safety, and latency in many IoT applications, intelligent decisions must be made right here right now at the network edge. However, the constrained resources and limited local data amount pose significant challenges to the development of edge AI. To overcome these challenges, we explore continual edge learning capable of leveraging the knowledge transfer from previous tasks. Aiming to achieve fast and continual edge learning, we propose a platform-aided federated meta-learning architecture where edge nodes collaboratively learn a meta-model, aided by the knowledge transfer from prior tasks. The edge learning problem is cast as a regularized optimization problem, where the valuable knowledge learned from previous tasks is extracted as regularization. Then, we devise an ADMM based federated meta-learning algorithm, namely ADMM-FedMeta, where ADMM offers a natural mechanism to decompose the original problem into many subproblems which can be solved in parallel across edge nodes and the platform. Further, a variant of inexact-ADMM method is employed where the subproblems are `solved' via linear approximation as well as Hessian estimation to reduce the computational cost per round to $\mathcal{O}(n)$. We provide a comprehensive analysis of ADMM-FedMeta, in terms of the convergence properties, the rapid adaptation performance, and the forgetting effect of prior knowledge transfer, for the general non-convex case. Extensive experimental studies demonstrate the effectiveness and efficiency of ADMM-FedMeta, and showcase that it substantially outperforms the existing baselines.

description: In this work, we analyze in detail the problem of piston driven shock waves in planar media. Similarity solutions to the compressible hydrodynamics equations are developed, for a strong shock wave, generated by a time dependent pressure piston, propagating in a non-homogeneous planar medium consisting of an ideal gas. Power law temporal and spatial dependency is assumed for the piston pressure and initial medium density, respectively. The similarity solutions are written in both Lagrangian and Eulerian coordinates. It is shown that the solutions take various qualitatively different forms according to the value of the pressure and density exponents. We show that there exist different families of solutions for which the shock propagates at constant speed, accelerates or slows down. Similarly, we show that there exist different types of solutions for which the density near the piston is either finite, vanishes or diverges. Finally, we perform a comprehensive comparison between the planar shock solutions and Lagrangian hydrodynamic simulations, by setting proper initial and boundary conditions. A very good agreement is reached, which demonstrates the usefulness of the analytic solutions as a code verification test problem.

description: This study examines the feasibility of cross-hedging cottonseed meal with soybean meal futures. A simple linear regression of cottonseed meal cash prices on soybean meal futures provides a direct price movement relationship. Using the estimated hedge ratios, the net realized prices are calculated for seven different cash markets. The net realized prices are higher than cash prices in three of the four years evaluated. The empirical analyses suggest soybean meal futures can be used as a potential cross-hedging vehicle for cash cottonseed meal.

description: Most new futures contracts fail. This study estimates the effects of several factors on the success or failure of agricultural futures contracts. Commodities with futures markets and without futures markets are included. Characteristics for which no data exist, such as homogeneity, vertical integration, buyer concentration, and activeness of the cash market, are measured by the Delphi approach. An active cash market is found to be necessary for futures contract success since this variable alone perfectly predicts whether or not a commodity has a futures market.

description: We derive the Bethe ansatz equations describing the complete spectrum of the transition matrix of the partially asymmetric exclusion process with the most general open boundary conditions. For totally asymmetric diffusion we calculate the spectral gap, which characterizes the approach to stationarity at large times. We observe boundary induced crossovers in and between massive, diffusive and KPZ scaling regimes.
