description: Kunststoffabfälle aus Einweg-Lebensmittelverpackungen sind eine der größten ökologischen Herausforderungen der Gegenwart. Eine Reduktion des Abfalls kann jedoch nicht alleine durch eine Optimierung des Verpackungsmaterials erfolgen. Verpackungen müssen vielmehr als Schnittstelle zwischen multiplen Praktiken analysiert und bearbeitet werden. Auf Basis dieser praxistheoretischen Perspektive identifizieren wir vier Vermittlerrollen von Verpackungen innerhalb von Praktiken-Netzwerken der Lebensmittelversorgung: sie fungieren als flexibler Körper, abfragbares Gehirn, vertrautes Gesicht und helfende Hand von Produkten. Am Beispiel von Getränkeverpackungen diskutieren wir, wie solche Praktiken-Netzwerke auf ressourcenschonendere Weise umgestaltet und trotzdem die Vermittlerrollen von Verpackungen aufrechterhalten werden können. Weiterhin stellen wir das visionäre Konzept „Precycling“ vor, um die (veränderten) Praktiken nicht nur zu analysieren, sondern auch in Richtung Abfallvermeidung zu transformieren. Dabei zeigen wir, dass sich der Begriff Precycling insbesondere für die Kollaboration zwischen unterschiedlichsten Akteursgruppen eignet, die Teil der Praktiken-Netzwerke sind. Plastic waste from single-use food packaging is one of the greatest environmental challenges of today. However, waste reduction cannot be achieved by optimizing the packaging material alone. Rather, packaging must be analyzed and addressed as an interface between multiple practices. Based on this practice-theoretical perspective, we identify four mediating roles of packaging within networks of food supply practices: it acts as a flexible body, queryable brain, saving face and helping hand of products. We apply this heuristic to the example of beverage packaging showing how practices need to change for more resource-efficient solutions while still maintain the mediating roles of packaging. Furthermore, we introduce the visionary concept of “precycling“ to not only analyze but also transform (changing) practices towards waste prevention. In doing so, we show that the concept of precycling is particularly suited to collaborations between a wide variety of actor groups that are part of networks of practices. (peer reviewed)

description: In the Entropic Dynamics (ED) approach to quantum theory the particles have well-defined positions but since they follow non differentiable Brownian trajectories they cannot be assigned an instantaneous momentum. Nevertheless, four different notions of momentum can be usefully introduced. We derive relations among them and the corresponding uncertainty relations. The main conclusion is that momentum is a statistical concept: in ED the momenta are not properties of the particles; they are attributes of the probability distributions.

description: If massive sterile neutrinos exist, their decays into photons and/or electron-positron pairs may give rise to observable consequences. We consider the possibility that MeV sterile neutrino decays lead to the diffuse positron annihilation line in the Milky Way center, and we thus obtain bounds on the sterile neutrino decay rate $Γ_e \ge 10^{-28}$ s$^{-1}$ from relevant astrophysical/cosmological data. Also, we expect a soft gamma flux of $1.2 \times 10^{-4}-9.7 \times 10^{-4}$ ph cm$^{-2}$ s$^{-1}$ from the Milky Way center which shows up as a small MeV bump in the background photon spectrum. Furthermore, we estimate the flux of active neutrinos produced by sterile neutrino decays to be $0.02-0.1$ cm$^{-2}$ s$^{-1}$ passing through the earth.

description: We study the spectrum of a one-dimensional Kitaev chain placed in a microwave cavity. In the off-resonant regime, the frequency shift of the cavity can be used to identify the topological phase transition of the coupled system. In the resonant regime, the topology of the system can be controlled via the microwave cavity occupation and, moreover, for a large number of photons (classical limit), the physics becomes similar to that of periodically-driven systems (Floquet insulators). We also analyze numerically a finite chain and show the existence of a degenerate subspace in the presence of the cavity that can be interpreted as a \textit{Majorana polariton}.

description: Operating rooms are the most important assets of hospitals whose capacity allocation to different specialties is critical and challenging. This paper proposes a hybrid simulation and optimisation approach for the strategic surgery capacity allocation problem over a yearly horizon. First, a simulation model is proposed to specify an appropriate percentage of the total available time of operating rooms in each period which is allocated to emergency patients. Then, a new mathematical model is developed to determine the optimal capacity plan (i.e. resource allocation) for operating rooms by handling both elective and emergency patients under uncertainty of surgery demands, surgery times and length of stays. The model aims to minimise the total under-time and the number of patients on the waiting list according to their surgery priorities. A tailored fix and relax algorithm is devised to solve the problem efficiently. Finally, a real case study in a private hospital along with some test problems are provided to evaluate the proposed model and its solution method. The numerical results demonstrate the desirable performance of the proposed solution approach. Moreover, the results indicate a significant reduction in the total under-time and the number of beds allocated in each period.

description: Heterostructures of Dirac materials such as graphene and topological insulators provide interesting platforms to explore exotic quantum states of electrons in solids. Here we study the electronic structure of graphene-Sb2Te3 heterostructure using density functional theory and tight-binding methods. We show that the epitaxial graphene on Sb2Te3 turns into quantum spin-Hall phase due to its proximity to the topological insulating Sb2Te3. It is found that the epitaxial graphene develops a giant spin-orbit gap of about ~20 meV, which is about three orders of magnitude larger than that of pristine graphene. We discuss the origin of such enhancement of the spin-orbit interaction and possible outcomes of the spin-Hall phase in graphene.

description: Der Artikel liefert eine historisch-rekonstruierende Untersuchung des Umgangs der deutschen Stromkonzerne E.ON, RWE, EnBW und Vattenfall mit erneuerbaren Energien. Die Haltung der Unternehmen wandelte sich in den zurückliegenden dreißig Jahren von einer antagonistischen Ablehnung erneuerbarer Energien bis zu einer Fokussierung auf diesen Geschäftsbereich. Die Untersuchung baut auf einer breiten Rezeption der sozialwissenschaftlichen Theoriediskussion zu organisationaler Trägheit auf und entwickelt einen forschungspraktischen Analyserahmen, der verschiedene Dimensionen und Mechanismen des Phänomens unterscheidet. Auf Basis von Interviews mit Führungskräften, der qualitativen Inhaltsanalyse von Unternehmens- und Presseberichten und quantitativen Zeitreihen wird der Prozess der Reorientierung der Stromkonzerne theoriegeleitet rekonstruiert. Der Text leistet einen Beitrag zu einer reflexiv-beobachtenden Nachhaltigkeitsforschung, indem er den Blick auf die innerorganisationalen Hindernisse nachhaltiger sektoraler Transformation und die Voraussetzungen zu deren Überwindung lenkt. This article provides a historical-reconstructive analysis of the approach to renewable energies taken by German electricity companies E.ON, RWE, EnBW and Vattenfall. Over the past 30 years, the companies’ strategy has changed from an antagonistic rejection of renewable energies to a focus on this business sector. The study builds on a broad reception of the debate on organisational inertia in social science and presents it in an analytical framework that identifies different dimensions and mechanisms of organisational inertia. This paper offers a theory-guided reconstruction of the process of reorientation by electricity companies based on interviews with executives, a qualitative content analysis of business and press reports, and quantitative time series. The paper aims to contribute to a sociology of sustainability by drawing attention to the intra-organisational obstacles to sustainable sectoral transformation and the opportunities for overcoming them.

description: This work aims to address the problem of green supply chain planning in the petroleum industry. Our primary objective is to minimize the total cost of crude, refinery, and petrochemical sectors and meet environmental regulations. It presents an optimization model for planning the supply chain. Furthermore, the study examines the impact of incorporating investment decisions in different carbon emission reduction options and evaluating the supply chain performance based on the economic and environmental dimensions. A novel mixed-integer linear programming model is developed to assess the impact of introducing a stringent environmental regulation limiting greenhouse gas emissions. Experimental results based on the Libyan petroleum industry are analyzed and demonstrate model capabilities to deal with the trade-off between the total cost and environmental issues. A sensitivity analysis is carried out on some parameters to design a mitigation plan to manage the environmental risks. This study shows that it is possible to reduce carbon emissions by up to 32% if the carbon capture and storage projects are implemented in the petroleum sector. However, if the reduction objective is more than 32% for the next 20 years, it is necessary to implement green (solar) energies in extraction, refineries, and petrochemical plants.

description: We present the first determination of charge symmetry violation (CSV) in the spin-dependent parton distribution functions of the nucleon. This is done by determining the first two Mellin moments of the spin-dependent parton distribution functions of the octet baryons from N_f = 2 + 1 lattice simulations. The results are compared with predictions from quark models of nucleon structure. We discuss the contribution of partonic spin CSV to the Bjorken sum rule, which is important because the CSV contributions represent the only partonic corrections to the Bjorken sum rule.

description: Despite the growth of group purchasing, few studies consider group purchasing with bundled products. Generally, an individual buyer may be reluctant to buy a bundle and prefer to buy a portion of it. By group buying, buyers purchase their products with lower price. We proposed a group purchasing structure for bundles of items in which buyers’ purchasing power is a function of time and bundles’ expiration date. A platform is also considered that charges sellers after selling their bundles. Three strategies are proposed in terms of three problems. In problem (I), a group of buyers wants to buy those products whose bundle price they can pay for in full and maximise their total savings. In problem (II), which is an extension of problem (I), the products’ importance is also considered. In problem (III), cohorts of buyers try to buy all their products, and the platform could pay the remaining price of the unsuccessful bundles. Here, the remaining products are in the platform’s ownership. Based on the results, while the first strategy accounts for most of buyers’ savings, the other two strategies allow more purchases. The highest platform income is for problem (III) due to the possibility of selling additional products.

description: This study aims to optimize cross-docking (CD) performance and efficiency in CD assignment problems by maximising forklift utilisation inside the terminal. ‘We present a new Mixed-Integer Nonlinear programming (MINLP)’ model that considers truck-door assignment and forklift utilisation inside the airport. One objective is to enhance the quality of truck-door by minimising the total transshipment costs, including the penalty cost associated with forklift underutilisation, the total forklift travel distance cost, and the total weighted loading unloading and operator cost. Another objective is to control the forklift congestion by minimising the total number of forklifts needed to transfer products between multiple doors inside the terminal. Two algorithms, including the tabu-search and the best-local-point-finder, are proposed to accomplish these objectives. Our computational results show the advantage of the proposed algorithms over the CPLEX commercial solver.

description: The ternary stannide CeRuSn is a static mixed-valent cerium compound with an or-dering of trivalent and intermediate-valent cerium on two distinct crystallographic sites. 119Sn Mössbauer spectra showed two electronically almost identical tin atoms at 323 K, while at 298 K and below (77 and 4.2 K) two tin sites can clearly be distinguished. 119Sn solid state NMR experiments are performed to probe the local hyperfine fields at the two different Sn sites. 119Sn NMR powder spectra are nicely fitted with two Sn sites with nearly the same magnetic anisotropy, but with different absolute shift values. Both Sn sites are strongly affected by crossover-like transitions between 100 and 280 K. This local-site study confirms the superstructure modulations found in previous investiga-tions. Towards lower temperatures the powder spectra are broadened giving strong evidence for the antiferromagnetically ordered ground state.

description: A comprehensive cladistic analysis of the extant genera of the Family Mustelidae was performed employing, 27 characters based on cranial and dental morphology. The analysis utilized an unrestricted parsimony computer programme (PAUP) and binary characters. A morphometric study of head shape was also performed to identify discriminators between genera. Shape similarities and differences were compared with the phylogenetic hypotheses. The phylogenetic analysis employed the outgroup method to polarize characters. Based on the data set, no autapomorphs were identified for a traditionally recognized family - the Procyonidae. Within the Mustelidae, there appears to be a number of distinct clades. Group I is proposed for the clade containing the musteline and lutrine genera. Within this group, the exact relationship of Enhydra is still_unclear, as is the internal arrangement of the three lutrine genera. The rnustelines contain a wide variety of forms, some of which may not merit separate generic rank (Poecilictis, Vormela and Ictonyx). The second major clade is Group II. The genera included are from three traditionally recoqnized subfamilies (Melinae, Mellivorinae and Mephitinae) which are no longer considered valid. The third clade is the single genus, Melogale. Formerly a part of the subfamily Melinae, it appears, rather, to be the primitive sister group to Group I. The morphornetric analys"is is somewhat inconclusive. Employing a form of discriminant analysis - Canonical Variate Analysis - plots of the "best" combinations of variables (best at discriminating) show three groups. Well separate are the lutrines, incluoing Enhydra. A loose collection of the larger-bodied forms falls in between the lutrines and the last group. The final cluster is composed of the smaller forms. It is proposed that the dense cluster of the small forms represents a small carnivore head morphology possibly constrained by mechanical requirements. Further tests of this proposal, though, are necessary.

description: The motion of a cylindrical crystalline nanoparticle sandwiched between two crystalline planes, one stationary and the other pulled at a constant velocity and pressed down by a normal load, is considered theoretically using a planar model. The results of our model calculations show that, depending on load and velocity, the nanoparticle can be either rolling or sliding. At sufficiently high normal loads, several sliding states characterized by different friction forces can coexist, corresponding to different orientations of the nanoparticle, and allowing one to have low or high friction at the same pulling velocity and normal load.

The frequency dependent scattering rate shows a pseudogap extending into the overdoped regime. We found that the effective mass enhancement calculated from the optical conductivity is constant throughout the phase diagram. Conversely, the effective optical charge density varies almost linearly with doping. Our results suggest that the low frequency electrodynamics of Bi(2)Sr(2-x)La(x)CuO(6) is not strongly affected by the long range Mott transition.

description: Intelligent systems in engineering structures are systems that can automatically adjust the structure's behavior in response to unanticipated loading in order to improve safety, increase the structure's life, and increase its efficiency. Manufacturing and development of smart materials is one of the new technologies that allows us to attain these goals. Shape memory alloys are one type of material with super elastic characteristics. One of the applications of these materials in passive structure control is their use as bolt and nut connectors. The use of super elastic materials in these energy-consuming systems increases ductility and, more critically, restores ability, resulting in acceptable seismic performance. In this research, ABAQUS software was used for cyclic nonlinear analysis to explore the seismic behavior of steel beam-to-column connections, beam-to-column connections equipped with shape memory alloy, and screw connections employing high-strength screws. The obtained results reveal that the beam-to-column connection equipped with shape memory alloy has great energy absorption and reversibility, allowing it to restore the starting conditions and reduce residual deformations.

description: Transport of cold atoms in shallow optical lattices is characterized by slow, nonstationary momentum relaxation. We here develop a projector operator method able to derive in this case a generalized Smoluchowski equation for the position variable. We show that this explicitly non-Markovian equation can be written as a systematic expansion involving higher-order derivatives. We use the latter to compute arbitrary moments of the spatial distribution and analyze their multifractal properties.

description: The study “Global Citizenship Education in the classroom. An exploratory study on teachers’ views” aims at describing teachers’ views on possible goals and practices on GCE in two different contexts: Central Italy (2017-2018) and Queensland (2019), Australia. To this end, the research analyses teaching strategies devoted to promoting dialogue among students and between teachers and students. The research specifically focuses on how secondary schools’ teachers promote the development of knowledge and skills related to GCE, in their verbal and nonverbal interactions. The study follows a qualitative methodology, adopting classroom observations in secondary schools and interviews to teachers focused on GCE aims and learning activities. In addition, in Italy a set of video-analysis was carried out in order to retrieve data for the documentation and representation of verbal and non-verbal interactions between teachers and students. Finding could indicate opportunities and challenges teachers face in dealing with topics related to global citizenship. The data referring to Italian context were collected in 2018. In Australia data were collected throughout 2019. On the short term, this explorative study intends to provide insights on GCE teaching practices and relative constructs possible operativization; and to support teachers’ professional development through critical reflection. On the medium-long term, the study could have an impact in: building or reinforcing networks between schools and Higher Education institutions, both at a national and at an international level; promoting in Italy educational change and disseminate innovative teaching knowledge and practices; outlining possible pathways to improve GCE teaching practices both in Australia and in Italy.

Abstract  Finerenone (Kerendia®), a first-in-class, orally administered, nonsteroidal mineralocorticoid receptor antagonist (MRA), is being developed by Bayer Healthcare Pharmaceuticals for the treatment of diabetic kidney disease (DKD) and heart failure (HF), including chronic HF (CHF). Finerenone has been approved in the USA to reduce the risk of sustained estimated glomerular filtration rate (eGFR) decline, end stage renal disease (ESRD), cardiovascular death, nonfatal myocardial infarction (MI), and hospitalization for HF in adults with chronic kidney disease (CKD) associated with type 2 diabetes (T2D). Finerenone is undergoing regulatory assessment in the EU and in China. A phase III trial is investigating finerenone in patients who have HF with preserved ejection fraction. This article summarizes the milestones in the development of finerenone leading to this first approval to reduce the risk of serious kidney and heart complications in adults with CKD and T2D. © Springer Nature Switzerland AG 2021
Modeling near-field radiative heat transfer from sharp objects using a general 3d numerical scattering technique

description: We examine the non-equilibrium radiative heat transfer between a plate and finite cylinders and cones, making the first accurate theoretical predictions for the total heat transfer and the spatial heat flux profile for three-dimensional compact objects including corners or tips. We find qualitatively different scaling laws for conical shapes at small separations, and in contrast to a flat/slightly-curved object, a sharp cone exhibits a local \emph{minimum} in the spatially resolved heat flux directly below the tip. The method we develop, in which a scattering-theory formulation of thermal transfer is combined with a boundary-element method for computing scattering matrices, can be applied to three-dimensional objects of arbitrary shape.

Compressive Imaging using Approximate Message Passing and a Markov-Tree Prior
Creators: name: Som, Subhojit
name: Schniter, Philip
Publisher: name: arXiv
Year: 2011
Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)
subject: FOS: Computer and information sciences

description: We propose a novel algorithm for compressive imaging that exploits both the sparsity and persistence across scales found in the 2D wavelet transform coefficients of natural images. Like other recent works, we model wavelet structure using a hidden Markov tree (HMT) but, unlike other works, ours is based on loopy belief propagation (LBP). For LBP, we adopt a recently proposed "turbo" message passing schedule that alternates between exploitation of HMT structure and exploitation of compressive-measurement structure. For the latter, we leverage Donoho, Maleki, and Montanari's recently proposed approximate message passing (AMP) algorithm. Experiments with a large image database suggest that, relative to existing schemes, our turbo LBP approach yields state-of-the-art reconstruction performance with substantial reduction in complexity.
The space density and X-ray luminosity function of non-magnetic cataclysmic variables

description: We combine two complete, X-ray flux-limited surveys, the ROSAT Bright Survey (RBS) and the ROSAT North Ecliptic Pole (NEP) survey, to measure the space density (ρ) and X-ray luminosity function (Φ) of non-magnetic CVs. The combined survey has a flux limit of F_X \ga 1.1 \times 10^{-12} erg cm^{-2}s^{-1} over most of its solid angle of just over 2π, but is as deep as \simeq 10^{-14} erg cm^{-2}s^{-1} over a small area. The CV sample that we construct from these two surveys contains 20 non-magnetic systems. We carefully include all sources of statistical error in calculating ρand Φby using Monte Carlo simulations; the most important uncertainty proves to be the often large errors in distances estimates. If we assume that the 20 CVs in the combined RBS and NEP survey sample are representative of the intrinsic population, the space density of non-magnetic CVs is 4^{+6}_{-2} \times 10^{-6} pc^{-3}. We discuss the difficulty in measuring Φin some detail---in order to account for biases in the measurement, we have to adopt a functional form for Φ. Assuming that the X-ray luminosity function of non-magnetic CVs is a truncated power law, we constrain the power law index to -0.80 \pm 0.05. It seems likely that the two surveys have failed to detect a large, faint population of short-period CVs, and that the true space density may well be a factor of 2 or 3 larger than what we have measured; this is possible, even if we only allow for undetected CVs to have X-ray luminosities in the narrow range 28.7< log(L_X/erg\,s^{-1})<29.7. However, ρas high as 2 \times 10^{-4} pc^{-3} would require that the majority of CVs has X-ray luminosities below L_X = 4 \times 10^{28} erg s^{-1} in the 0.5--2.0 keV band.

description: A thorough understanding of the changes in mechanical property behind intracellular biophysical and biochemical processes during differentiation of human mesenchymal stem cells (hMSCs) is helpful to direct and enhance the commitment of cells to a particular lineage. In this study, displacement creep of the mesenchymal cell lineages (osteogenic, chondrogenic and adipogenic hMSCs) were determined by using atomic force microscopy, which were then used to determine their mechanical properties. We found that at any stages of differentiation, the mesenchymal cell lineages are linear viscoelastic materials and well matched with a simple power-law creep compliance. In addition, the viscoelasticity of mesenchymal cell lineages showed different trends during differentiation. The adipogenic hMSCs showed continuous softening at all stages. The osteogenic and chondrogenic hMSCs only continuously soften and become more fluid-like in the early stage of differentiation, and get stiffened and less fluid-like in the later stage. These findings will help more accurately imitate cellular biomechanics in the microenvironment, and provided an important reference in the biophysics biomimetic design of stem cell differentiation.

description: LOFAR is a groundbreaking low-frequency radio telescope currently nearing completion across northern europe. As a software telescope with no moving parts, enormous fields of view and multi-beaming, it has fantastic potential for the exploration of the time-variable universe. In this brief paper I outline LOFAR's capabilities, as well as our plans to use it for a range of transient searches and some crude estimated rates of transient detections.

description: In this paper, we study the p-ary linear code C(PG(n, q)), q = p^h, p prime, h >= 1, generated by the incidence matrix of points and hyperplanes of a Desarguesian projective space PG(n, q), and its dual code. We link the codewords of small weight of this code to blocking sets with respect to lines in PG(n, q) and we exclude all possible codewords arising from small linear blocking sets. We also look at the dual code of C(PG(n,q)) and we prove that find- ing the minimum weight of the dual code can be reduced to finding the minimum weight of the dual code of points and lines in PG(2, q). We present an improved upper bound on this minimum weight and we show that we can drop the divisibility condition on the weight of the codewords in Sachar's lower bound [12].

description: Temporal changes of X-ray to very-high-energy gamma-ray emissions from the pulsar-Be star binary PSR B1259-63/LS 2883 are studied based on 3-D SPH simulations of pulsar wind interaction with Be-disk and wind. We focus on the periastron passage of the binary and calculate the variation of the synchrotron and inverse-Compton emissions using the simulated shock geometry and pressure distribution of the pulsar wind. The characteristic double-peaked X-ray light curve from observations is reproduced by our simulation under a dense Be disk condition (base density ~10^{-9} g cm^{-3}). We interpret the pre- and post-periastron peaks as being due to a significant increase in the conversion efficiency from pulsar spin down power to the shock-accelerated particle energy at orbital phases when the pulsar crosses the disk before periastron passage, and when the pulsar wind creates a cavity in the disk gas after periastron passage, respectively. On the contrary, in the model TeV light curve, which also shows a double peak feature, the first peak appears around the periastron phase. The possible effects of cooling processes on the TeV light curve are briefly discussed.
