description: Transient effects in the microwave second-order response of YBaCuO powder are investigated. The time evolution of the second harmonic signal has been measured for about 300 s after the sample had been exposed to variations of the DC magnetic field. We show that in different time scales the transient response has different origin. In the time scale of milliseconds the transient response of samples in the critical state is ascribable to processes of flux redistribution induced by the switching on/off of the microwave field. At longer times, the time evolution of the second harmonic signal can be ascribed to motion of fluxons induced by the variation of the DC magnetic field. In particular, diffusive motion of fluxons determines the response in the first 10 seconds after the stop of the magnetic field variation; magnetic relaxation over the surface barrier determines the response in the time scale of minutes.

description: The first harvest of Humulus lupulus (var. Cascade) in Brazil in 2016 originated as an aromatic hop that nowadays is gaining attention from the brewery industry. However, the chemical composition and the properties of this hop have not been well documented to date. In this study, the chemical profile of the phenolic compounds and essential oils of Cascade hops produced in Brazil (BH) and the USA (UH) was determined. The major phenolic compounds identified by LC-ESI-MS-MS in BH and UH were protocatechuic acid, isoquercitrin, and ferulic acid (4.18–11.39; 2.44–4.90; and 1.45–4.48 mg 100 g−1, respectively). The profile of essential oils was shown to differ between the two samples. The compounds trans-β-farnesene (20.60%), β-selinene (18.78%), myrcene (16.57%), and α-selinene (16.22%) were the main compounds in the BH essential oil, while the essential oil of UH showed a high content of α-humulene (35.35%), myrcene (22.35%), β-caryophyllene (12.81%), and trans-β-farnesene (10.59%). A higher antioxidant activity (by DPPH and ABTS) was observed for hop extracts when compared to the essential oils. The results indicated that the Brazilian hop sample analyzed had higher radical scavenging when compared to an American hop sample (associated with its bioactive compound composition). The Cascade hop from Brazil appears to be a high-quality raw material showing significant potential for future industrial applications.

description: We give here the derivation of a Gross-Pitaevskii--type equation for inhomogeneous condensed bosons. Instead of the original Gross-Pitaevskii differential equation, we obtain an integral equation that implies less restrictive assumptions than are made in the very recent study of Pieri and Strinati [Phys. Rev. Lett. 91 (2003) 030401]. In particular, the Thomas-Fermi approximation and the restriction to small spatial variations of the order parameter invoked in their study are avoided.

description: We consider network models of quantum localisation in which a particle with a two-component wave function propagates through the nodes and along the edges of an arbitrary directed graph, subject to a random SU(2) rotation on each edge it traverses. The propagation through each node is specified by an arbitrary but fixed S-matrix. Such networks model localisation problems in class C of the classification of Altland and Zirnbauer, and, on suitable graphs, they model the spin quantum Hall transition. We extend the analyses of Gruzberg, Ludwig and Read and of Beamond, Cardy and Chalker to show that, on an arbitrary graph, the mean density of states and the mean conductance may be calculated in terms of observables of a classical history-dependent random walk on the same graph. The transition weights for this process are explicitly related to the elements of the S-matrices. They are correctly normalised but, on graphs with nodes of degree greater than 4, not necessarily non-negative (and therefore interpretable as probabilities) unless a sufficient number of them happen to vanish. Our methods use a supersymmetric path integral formulation of the problem which is completely finite and rigorous.

description: Can public social media data be harnessed to predict COVID-19 case counts? We analyzed approximately 15 million COVID-19 related posts on Weibo, a popular Twitter-like social media platform in China, from November 1, 2019 to March 31, 2020. We developed a machine learning classifier to identify "sick posts," which are reports of one's own and other people's symptoms and diagnosis related to COVID-19. We then modeled the predictive power of sick posts and other COVID-19 posts on daily case counts. We found that reports of symptoms and diagnosis of COVID-19 significantly predicted daily case counts, up to 14 days ahead of official statistics. But other COVID-19 posts did not have similar predictive power. For a subset of geotagged posts (3.10% of all retrieved posts), we found that the predictive pattern held true for both Hubei province and the rest of mainland China, regardless of unequal distribution of healthcare resources and outbreak timeline. Researchers and disease control agencies should pay close attention to the social media infosphere regarding COVID-19. On top of monitoring overall search and posting activities, it is crucial to sift through the contents and efficiently identify true signals from noise.

It is shown that, in principle, simple autoregressive models fitted to population time series can already do the job. MSY is attained in the single-stock case when the harvesting rate equals the populations return rate to equilibrium (independent of the production function).

description: A wide and critical comparison of the capability of Method of Characteristics, Explicit Path-Conservative Finite Volume Method and Semi-Implicit Staggered Finite Volume Method is presented and discussed, in terms of accuracy and efficiency. The viscoelastic behaviour of the pipe wall, the effects of the unsteadiness of the flow on the friction losses, cavitation and cross-sectional changes are considered. The analyses are performed comparing numerical solutions obtained using the three models against experimental data and analytical solutions. Water hammer studies in high density polyethylene pipes, for which laboratory data have been provided, are used as test cases. Considering the viscoelastic mechanical behaviour of plastic materials, a 3-parameter and a multi-parameter linear viscoelastic rheological model are adopted and implemented in each numerical scheme. Original extensions of existing techniques for the numerical treatment of such viscoelastic models are introduced in this work for the first time. After a focused calibration of the viscoelastic parameters, the different performance of the numerical models is investigated. A comparison of the results is presented considering the unsteady wall-shear stress, with a new approach proposed for turbulent flows, or simply considering a quasi-steady friction model. A predominance of the damping effect due to viscoelasticity with respect to the damping effect related to the unsteady friction is confirmed in these contexts. All the numerical methods show a good agreement with the experimental data and a high efficiency of the Method of Characteristics in standard configuration is observed. Three Riemann Problems are chosen and run to stress the numerical methods, considering cross-sectional changes, more flexible materials and cavitation cases. In these demanding scenarios, the weak spots of the Method of Characteristics are depicted.

description: We have studied the antiferromagnetic Ising chain in a transverse magnetic field $h_{x}$ and uniform longitudinal field $h_{z}$. Using the density matrix renormalization group calculation combined with a finite-size scaling the ground state phase diagram in ($h_{x},h_{z}$) plane is determined. It is shown that there is an order-disordered transition line in this plane and the critical properties belong to the universality class of the two-dimensional Ising model. Based on the perturbation theory in $h_{z}$ the scaling behavior of the mass gap in the vicinity of the critical point ($h_{x}=1/2,h_{z}=0$) is established. It is found that the form of the transition line near the classical multicritical point ($h_{x}=0,h_{z}=1$) is linear. The connection of the considered quantum model with the quasi-one-dimensional classical Ising model in the magnetic field is discussed.

description: Affordances are fundamental descriptors of relationships between actions, objects and effects. They provide the means whereby a robot can predict effects, recognize actions, select objects and plan its behavior according to desired goals. This paper approaches the problem of an embodied agent exploring the world and learning these affordances autonomously from its sensory experiences. Models exist for learning the structure and the parameters of a Bayesian Network encoding this knowledge. Although Bayesian Networks are capable of dealing with uncertainty and redundancy, previous work considered complete observability of the discrete sensory data, which may lead to hard errors in the presence of noise. In this paper we consider a probabilistic representation of the sensors by Gaussian Mixture Models (GMMs) and explicitly taking into account the probability distribution contained in each discrete affordance concept, which can lead to a more correct learning.

description: There is increasing interest in the development of new, ‘universal’ influenza vaccines (UIV) that––unlike current vaccines––are effective against a broad range of seasonal influenza strains, as well as against novel pandemic viruses. While the existing literature discusses the potential epidemiological benefits of UIVs, it is also important to anticipate their potential unintended population consequences. Using mathematical modelling, we illustrate two such types of adverse consequences. First, by reducing the amount of infection-induced immunity in a population without fully replacing it, a seasonal UIV programme may permit larger pandemics than in the absence of vaccination. Second, the more successful a future UIV programme is in reducing transmission of seasonal influenza, the more vulnerable the population could become to the emergence of a vaccine escape variant. These risks could be mitigated by optimal deployment of any future UIV vaccine: namely, the use of a combined vaccine formulation (incorporating conventional as well as multiple universal antigenic targets), and by achieving sufficient population coverage to compensate for any reductions in infection-induced immunity. In the absence of large-scale trials of UIVs, disease-dynamic models can provide helpful, early insights into their potential impact. In future, data from continuing vaccine development will be invaluable in developing robustly predictive modelling approaches.

description: Historically, farmhouse brewers made beer from their own grain all over northern Europe, using yeast they maintained in the local community. Previous authors have commented on the unusually high pitch temperatures, but no systematic study had been conducted to date. Based on documentary accounts and interviews, this study reports that high pitch temperatures were dominant in farmhouse brewing, and that roughly 60% of farmhouse brewers probably started fermentations at temperatures close to body temperature, according to a survey of 293 independent accounts of farmhouse brewing practices in ten different countries. This also suggests, but does not prove, that farmhouse brewers fermented their beer at very warm temperatures.

description: We present the results of the latest NuSTAR monitoring campaign of the Compton-thick Seyfert 2 galaxy NGC 1068, composed of four $\sim$50 ks observations performed between July 2017 and February 2018 to search for flux and spectral variability on timescales from 1 to 6 months. We detect one unveiling and one eclipsing event with timescales less than 27 and 91 days, respectively, ascribed to Compton-thick material with $N_H=(1.8\pm0.8)\times10^{24}$ cm$^{-2}$ and $N_H\geq(2.4\pm0.5)\times10^{24}$ cm$^{-2}$ moving across our line of sight. This gas is likely located in the innermost part of the torus or even further inward, thus providing further evidence of the clumpy structure of the circumnuclear matter in this source. Taking advantage of simultaneous Swift-XRT observations, we also detected a new flaring ULX, at a distance $d\sim$30" (i.e. $\sim$2 kpc) from the nuclear region of NGC 1068, with a peak X-ray intrinsic luminosity of $(3.0\pm0.4)\times10^{40}$ erg s$^{-1}$ in the 2-10 keV band.

We determine the spin mixing time to be typically less than 600 ms and observe spin population oscillations. The equilibrium spin configuration in the F=1 manifold is measured for different magnetic fields and found to show ferromagnetic behavior for low field gradients. An F=2 condensate is created by microwave excitation from F=1 manifold, and this spin-2 condensate is observed to decay exponentially with time constant 250 ms. Despite the short lifetime in the F=2 manifold, spin mixing of the condensate is observed within 50 ms.

description: This paper uses a unique household data set collected in Vietnam to empirically test the necessary conditions for an extended version of the consumption risk-sharing hypothesis. The test explicitly incorporates self-production and uses natural disasters such as avian influenza, droughts, and floods to identify the effectiveness of market and non-market risk-sharing mechanisms. With these additional treatments, full risk sharing cannot be rejected, which suggests the presence of omitted variable bias in existing studies that reject full risk sharing. We also find that credit constraints have a significant impact, although limited commitment is not necessarily serious.

description: We examine the practical identifiability of parameters in a spatio-temporal reaction–diffusion model of a scratch assay. Experimental data involve fluorescent cell cycle labels, providing spatial information about cell position and temporal information about the cell cycle phase. Cell cycle labelling is incorporated into the reaction–diffusion model by treating the total population as two interacting subpopulations. Practical identifiability is examined using a Bayesian Markov chain Monte Carlo (MCMC) framework, confirming that the parameters are identifiable when we assume the diffusivities of the subpopulations are identical, but that the parameters are practically non-identifiable when we allow the diffusivities to be distinct. We also assess practical identifiability using a profile likelihood approach, providing similar results to MCMC with the advantage of being an order of magnitude faster to compute. Therefore, we suggest that the profile likelihood ought to be adopted as a screening tool to assess practical identifiability before MCMC computations are performed.

description: In order to ensure and improve quality in the agro-food sector, quality systems have to undergo constant change: simple end of the pipe monitoring is being replaced by management-oriented regimes (Enneking et al., 2007). Increasing, farmers, too, are required to implement quality systems. A variety of quality assurance systems has been developed for use at the primary production level over the last few years. They differ widely, however, with respect to their requirement levels, regional scope of application, degree of integration into the supply chain or their institutional supports. The aim of this study is to ascertain specific factors that influencing the acceptance of quality management systems at the Pangasius farm level.

description: Determining the underlying principles behind biological regulation is important for understanding the principles of life, treating complex diseases and creating de novo synthetic biology. Buffering—the use of reservoirs of molecules to maintain molecular concentrations—is a widespread and important mechanism for biological regulation. However, a lack of theory has limited our understanding of its roles and quantified effects. Here, we study buffering in energy metabolism using control theory and novel buffer analysis. We find that buffering can enable the simultaneous, independent control of multiple coupled outputs. In metabolism, adenylate kinase and AMP deaminase enable simultaneous control of ATP and adenylate energy ratios, while feedback on metabolic pathways is fundamentally limited to controlling one of these outputs. We also quantify the regulatory effects of the phosphagen system—the above buffers and creatine kinase—revealing which mechanisms regulate which outputs. The results are supported by human muscle and mouse adipocyte data. Together, these results illustrate the synergy of feedback and buffering in molecular biology to simultaneously control multiple outputs.

Ecosystem observation, processes and dynamics

Changes in migration can be expected to have impacts on the invaded ecosystem for bad or good through for example predation on native species, competition with native species for limited food resources, and/or being a prey for native species. Since around 2006 Northeast Atlantic mackerel (NEAM) has been extending its summer feeding distribution towards north and west, associated with increased sea temperature. The objective of this paper is to evaluate the ecological meaning and impacts of this extension on the ecosystem around Iceland through (i) exploration of its diet composition in comparison to those of two herring stocks feeding in the same area, (ii) providing estimates of weight gain and total food consumption of NEAM there, and (iii) exploring the inter-annual variation in body condition of the three fish stocks. The results show that calanoidea was in highest mass in NEAMs’ stomachs in most areas while calanoidea and euphausiacea in herring. Fish prey was in higher proportion in NEAM than herring. NEAM in Icelandic waters increased in weight by 42%, 43% and 55%, during the summers in 2009–2011, respectively . Considering its abundance estimates in 2010 and 2011 in Icelandic waters, this corresponds to consumption of around 2.2 million tons each year. This invasion does not have apparent impacts on inter-annual variability in body condition of the herring stocks, while NEAM shows a decreasing trend in condition in the area.

description: This project argues that representations of landscape are used to communicate political and ideological agendas. Whether removing untidy nonhuman nature to create an idealistic picturesque image, or erasing indigenous populations to create the image of an untouched wilderness, representations of nature are not neutral, but absolutely political. This project makes the claim that the images of landscape that were born in the 17th and 18th centuries continue to serve as an archetype for the production of built landscapes, and are therefore implicated in setting the scene for the anthropocene (an era characterized by unprecedented environmental degradation, species loss, and social inequities). With retrospective awareness, landscape designers are presented with an opportunity to either continue to perpetuate a dichotomous image of landscape that treats nature as a subordinate other, or to explore alternative narratives that embrace cyborg nature: part culture- part organism.
title: Object-Oriented Software Representation of Polymer Materials Information in Engineering Design

Publisher: name: The Open University

description: The software application POISE, Polymer Objects in a Smalltalk™ Environment, integrates knowledge representation, user interfaces, and data management; a system of tools for the materials domain expert involved in design. Engineering design solutions initially build from generalisations. POISE represents multiple levels of generalisations from classifications of polymer information. The class-instance paradigm classifies software objects. An object’s behaviour is an exclusive function of its class. Polymer’s behaviours are a function of multiple orthogonal factors, like chemistry and processing, therefore multiple orthogonal classes must represent polymers. Taxonomy only represents one of these factors. The Enhancer mechanism resolves this conflict between classification and representation. Polymer classification is not well established, with new materials evolving. The software compensates by evolving the classification schema. Guided with a specialised interface tool, the domain expert updates the schema by adding new polymer families and re-classifying existing classes. Through analysing the generalisations in the classification, the domain expert can develop an appropriate classification. This analysis relies on the engineering properties differentiating the principal material qualities. Standard properties do not distinguish specific structural differences in polymer materials, necessitating new properties. Material properties distinguish materials in the domain whereas the classes describe the properties of polymer objects. Domain experts add new properties to the polymer classes to distinguish polymer objects. Properties are independent objects that partially describe the class template; Partial Template Objects. Persistence of personal design information and management of shared data requires dichotomous database management. Shared data requires multi-user access, and consequently transaction management. Transaction management in object-oriented systems often holds resources for a long duration. Transaction declaration hinders transparent access to storage, and corrupts the representation. For single-user design information, transactions are implicit with access. Database proxies provide transparent per-object transaction management to persistent design information. The WorkBase is an object-storage utility that utilises Enhancers as proxies.

description: No abstracts are to be cited without prior reference to the author.Distribution, abundance, and biology of polar cod, Boreogadus saida, was studied in the waters around Iceland based on material sampled during demersal fish surveys in March 1985-2011 and in pelagic 0-group surveys in August-September 1974-2003. Demersal polar cod were most often caught on the outer the shelf to the northwest of Iceland but during the years of highest abundance and widest distribution it was also caught on the north and northeastern shelves. Pelagic 0-group polar cod was only caught sporadically and confined to the waters over outer part of the northwestern shelf. Both distribution and abundance showed variations related to bottom temperature. Demersal polar cod was most widely distributed and peaks in abundance highest in the cold years of 1989-1999, 1994-1995 and 2002. A fourth peak in both abundance and distribution was observed during the somewhat warmer period of 2007-2009. On average highest numbers of polar cod per haul were caught at temperatures of 1.4° C and 0.14° C, and at depth ranges 55-100 m and 300- 400 m, respectively. The length of demersal polar cod ranged from 5-32 cm while the fish caught in the pelagic trawl ranged from 2.2-19 cm. The polar cod in north Icelandic waters most likely originates from east Greenland or even possibly Svalbard waters.

description: We investigate the dynamics of a sliding top that is a rigid body with an ideal sharp tip moving in a perfectly smooth horizontal plane, so no friction forces act on the body. We prove that this system is integrable only in two cases analogous to the Euler and Lagrange cases of the classical top problem. The cases with the constant gravity field with acceleration $g\neq0$ and without external field $g=0$ are considered. The non-integrability proof for $g\neq0$ based on the fact that the equations of motion for the sliding top are a perturbation of the classical top equations of motion. We show that the integrability of the classical top is a necessary condition for the integrability of the sliding top. Among four integrable classical top cases the corresponding two cases for the sliding top are also integrable, and for the two remaining cases, we prove their non-integrability by analyzing the differential Galois group of variational equations along a certain particular solution. In the absence of constant gravitational field $g=0$ the integrability is much more difficult. At first, we proved that if the sliding top problem is integrable, then the body is symmetric. In the proof, we applied one of the Ziglin theorem concerning the splitting of separatrices phenomenon. Then we prove the non-integrability of the symmetric sliding top using differential Galois group of variational equations except two the same as for $g\neq0$ cases. The integrability of these cases is also preserved when we add to equations of motion a gyrostatic term.
Correlation measures and the entanglement wedge cross-section after quantum quenches in two-dimensional conformal field theories

description: We consider the time evolution of mixed state correlation measures in two-dimensional conformal field theories, such as logarithmic negativity, odd entropy, and reflected entropy, after quantum quenches of various kinds. These correlation measures, in the holographic context, are all associated to the entanglement wedge cross section. We contrast various classes of conformal field theories, both rational and irrational (pure) conformal field theories. First, for rational conformal field theories, whose dynamics can be well described by the quasi-particle picture, we find all four quantities for disjoint intervals to be proportional, regardless of the specific quench protocol. Second, using the light cone bootstrap, we generalize our results to irrational conformal field theories where we find sharp distinctions from the quasi-particle results and striking differences between mutual information and the other measures. The large surplus of logarithmic negativity relative to mutual information forces us to reconsider what mutual information and logarithmic negativity really measure. We interpret these results as a signature of information scrambling and chaos in irrational theories. These CFT results perfectly agree with our gravitational (holographic) calculations. Furthermore, using holography, we are able to generalize the results to outside of the light cone limit. Finally, due to the breakdown of the quasi-particle picture for irrational theories, we appeal to the "line-tension picture," motivated by random unitary circuits, as a phenomenological description. We observe that random unitary circuits, with local Hilbert space dimension determined by the Cardy formula, have precisely the same entanglement dynamics as irrational (including holographic) conformal field theories.

description: No abstracts are to be cited without prior reference to the author.The impact of mesoscale eddies on the production of radiolarian species Rhizoplegma boreale in the central subarctic Pacific was investigated through analysis of sinking particle fluxes collected using sediment-trap and altimetry data from satellite observations. Altimetry observations provided the locations of mesoscale eddies in time and space and indicated that mesoscale eddies propagating around sediment trap Station SA were closely related to the high R. boreale fluxes at the station. The mesoscale eddies likely provided the deep-sea region of the central subarctic Pacific with coastal nutrient-rich waters derived from the region around the Aleutian Islands, and influenced the productivity of microzooplankton groups at Station SA.

description: Hard (alcoholic) ciders have grown rapidly since the early 2000s, but unlike beer and wine, there is limited scholarly research on their sensory attributes. The purpose of this study was to categorize and describe sensory and visual packaging and label attributes of ciders made in Virginia, United States using a labeled, free sorting task (a rapid sensory analysis method) with untrained panelists. In Study 1, N1=49 panelists tasted and sorted K=18 ciders into groups and labeled their groups. Then visually for Study 2, a second group of panelists (N2=61) sorted “photo sheets” of packaging and labels for the same K=18 ciders by two separate tasks: According to how they expected the cider to taste; and What occasion they would be most inclined to consume the cider at. Classical text analysis was used to analyze descriptors from both the sensory and visual free sorting tasks, and the terms were projected onto their respective compromise similarity maps that were produced using DISTATIS. Subjects identified and described distinct sensory styles and attributes among the evaluated ciders; however, descriptions provided by producers on their labels did not align well with panelist experienced sensory attributes. Consistent sorting patterns from the photo sheets emerged—providing a first look into how ciders might be valued based on packaging and labels alone. The results of this research will help cider producers develop favorable products that will satisfy consumer expectations and encourage repeat purchase.
