description: Background: Spin-triplet ($S=1$) proton-neutron (pn) pairing in nuclei has been under debate. It is well known that the dynamical pairing affects the nuclear matrix element of the Gamow-Teller (GT) transition and the double beta decay. Purpose: We investigate the effect of the pn-pair interaction in the $T=0, S=1$ channel on the low-lying spin-dipole (SD) transition. We then aim at clarifying the distinction of the role in between the SD and GT transitions. Method: We perform a three-body model calculation for the transition ${}^{80}\mathrm{Ni}\to{}^{80}\mathrm{Cu}$, where ${}^{78}\mathrm{Ni}$ is taken as a core. The strength of the pair interaction is varied to see the effect on the SD transition-strength distribution. To fortify the finding obtained by the three-body model, we employ the nuclear energy-density functional method for the SD transitions in several nuclei, where one can expect a strong effect. Results: The effect of the $S=1$ pn-pair interaction depends on the spatial overlap of the pn pair and the angular momentum of the valence nucleons; the higher the angular momentum of the orbitals, the more significant the effect. Conclusions: The dynamical $S=1$ pairing is effective even for SD states although the spatial overlap of the pn pair can be smaller than GT states. The SD transition involving high-$\ell$ orbitals with the same principal quantum number is strongly affected by the dynamical $S=1$ pairing.

description: Commercial powder bed fusion additive manufacturing systems use recoaters for the layer-by-layer distribution of powder. Despite the known limitations of recoaters, there has been relatively little work presented on the possible benefits of alternative powder delivery systems. Here, we show the use of a technology using simple vibration to control the powder flow for powder bed additive manufacturing. The capabilities of this approach are illustrated experimentally using two very different powders; a `conventional' gas atomized Ti-6Al-4V powder designed for electron beam additive manufacturing and a water atomized Fe-4wt\%Ni alloy used in powder metallurgy. Discrete element modelling is used to reveal the mechanisms controlling the dependence of feed rate on feeder process parameters and to investigate the potential strengths and limitations of this approach.

description: R E S U M OAs plantas alimentícias não convencionais (PANCs) podem ser utilizadas na alimentação humana, mas geralmente são negligenciadas. Essas espécies majoritariamente crescem de forma espontânea na natureza, sendo por vezes consideradas ervas daninhas e acabando por serem erradicadas. Considerando que essas plantas podem apresentar altos teores nutricionais, além de grande importância ecológica e cultural, o presente estudo teve como objetivo realizar o levantamento de PANCs ocorrentes na Floresta Nacional (FLONA) de Três Barras - SC, de forma a constatar a riqueza de espécies e trazer informações bibliográficas sobre suas propriedades químico-bromatológicas. Para realizar as coletas foi utilizado o método do caminhamento sistemático ao percorrer a trilha principal da FLONA e suas proximidades, enquanto que a identificação e as informações sobre as PANCs foram elaboradas a partir de literatura específica. O levantamento registrou um total de 29 espécies distribuídas em 19 famílias botânicas, com Asteraceae apresentando um número maior de representantes. Foi constatado que 48,2% das espécies apresentam porte arbóreo devido ao tipo de ambiente em que o estudo foi realizado, e que dentre as partes utilizadas para alimentação, os frutos e as folhas apareceram em maior número. Além do mais, foi possível perceber que as PANCs apresentam grande valor e diversidade nutricional, apesar de não receberem a devida atenção e importância.Palavras-Chaves: Flora Panc, Flona, Asteraceae, Espécies arbóreas.

description: The paper analyzes German students’ interest, perceived importance, knowledge, and behavior regarding food waste. This target group was expected to differ from the general population in terms of food consumption (shopping, cooking, and storage of food) and increased food waste due to their lifestyle. An online survey resulted in 253 participants enrolled in different study programs. Of the sample, 64% studied in life science programs, which were anticipated to have an impact on students’ behavior regarding food. Linear regression models were used to determine the importance of food waste avoidance to students, and their frequency of food disposal. In addition, students were asked about reasons for food waste and assessed statements for each consumption phase. High positive impacts were found for students’ general interest in food waste topics. They attested themselves sensible handling of food products, and rated themselves better than the average German consumer in all surveyed statements. For the target group of university students, detailed knowledge of food waste issues showed little influence on reported behaviors. In conclusion, awareness campaigns, while useful, should not be the only way to target a reduction in food waste, but have to be supplemented by other means.

description: Emission from Active Galactic Nuclei is known to vary strongly over time over a wide energy band, but the origin of the variability and especially of the inter-band correlations is still not well established. Here we present the results of our X-ray and optical monitoring campaign of the quasar MR2251-178, covering a period of 2.5 years. The X-ray 2-10 keV flux is remarkably well correlated with the optical B, V and R bands, their fluctuations are almost simultaneous with a delay consistent with 0 days and not larger than 4 days in either direction. The amplitude of variations shows an intriguing behaviour: rapid, large amplitude fluctuations over tens of days in the X-rays have only small counterparts in the optical bands, while the long-term trends over hundreds of days are stronger in the B band than in X-rays. We show that simple reprocessing models, where all the optical variability arises from the variable X-ray heating, cannot simultaneously explain the discrepant variability amplitudes on different time-scales and the short delays between X-ray and optical bands. We interpret the variability and correlations, in the optically-thick accretion disc plus corona scenario, as the result of intrinsic accretion rate variations modulating both X-ray and optical emission, together with reprocessing of X-rays by the accretion disc.

description: We discuss two new observational techniques that use observations of the Cosmic Microwave Background (CMB) to place constraints upon the mass, distance, and size distribution of small objects in the Kuiper Belt and inner Oort Cloud, collectively known as Trans-Neptunian Objects (TNOs). The first new technique considers the spectral distortion of the isotropic, or monopole, CMB by TNOs that have been heated by solar radiation to temperatures above that of the CMB. We apply this technique to the spectral measurements of the CMB by the Far Infrared Absolute Spectrophotometer (FIRAS) on the Cosmic Background Explorer (COBE). The second technique utilizes the change in amplitude of the TNO signal due to the orbital motion of the observer to separate the TNO signal from the invariant extra-galactic CMB and construct a map of the mass distribution in the outer Solar System. We estimate the ability of future CMB experiments to create such a map.

Numerical studies of some aspects with pressuremeter tests and laterally loaded piles
Creators: name: Yan, Li
Publisher: name: University of British Columbia
Year: 2010

description: elastic material with hyperbolic stress strain relation, is employed throughout. A thin interface element and a simple tension cut-off model simulating the soil-pile interface behavior has been incorporated in the program. Results of the program and the interface simulation are in good agreement with closed form solutions. From comparison of the responses of pressuremeter and lateral pile conditions, the pressuremeter curves can be adjusted to represent the P-Y curves. However, due to features of the loading mechanism, the installation has a different effect on pressuremeter curves than on P-Y curves. For pressuremeter curves, the initial stiffness is much affected by the soil disturbances, but the ultimate pressure is not significantly affected. The opposite effects are observed for P-Y curves. The practical significance of these effects in developing P-Y curves from pressuremeter expansion curves is discussed.

description: This paper addresses the problem of estimating the attitude and angular velocity of a rigid object by exploiting its second order kinematic model. The approach is particularly useful in cases where angular velocity measurements are not available and the attitude and angular velocity of an object need to be estimated from accelerometers and magnetometers. We propose a novel sensor modality that uses multiple accelerometers to measure the angular acceleration of an object as well as using magnetometers to measure partial attitude. We extend the approach of equivariant observer design to second order attitude kinematics by demonstrating that the special Euclidean group acts as a symmetry group on the system considered. The observer design is based on the lifted kinematics and we prove almost global asymptotic stability and local uniform exponential stability of the estimation error. The performance of the observer is demonstrated in simulation.

description: We demonstrate the applicability of the dressing method to the problem of constructing new classical solutions for Euclidean worldsheets in anti-de Sitter space. The motivation stems from recent work of Alday and Maldacena, who studied gluon scattering amplitudes at strong coupling using a generalization of a particular worldsheet found by Kruczenski whose edge traces a path composed of light-light segments on the boundary of AdS. We dress this `giant gluon' to find new solutions in AdS_3 and AdS_5 whose edges trace out more complicated, timelike curves on the boundary. These solutions may be used to calculate certain Wilson loops via AdS/CFT.

description: The development of artificial intelligence (AI) technologies has far exceeded the investigation of their relationship with society. Sociotechnical inquiry is needed to mitigate the harms of new technologies whose potential impacts remain poorly understood. To date, subfields of AI research develop primarily individual views on their relationship with sociotechnics, while tools for external investigation, comparison, and cross-pollination are lacking. In this paper, we propose four directions for inquiry into new and evolving areas of technological development: value--what progress and direction does a field promote, optimization--how the defined system within a problem formulation relates to broader dynamics, consensus--how agreement is achieved and who is included in building it, and failure--what methods are pursued when the problem specification is found wanting. The paper provides a lexicon for sociotechnical inquiry and illustrates it through the example of consumer drone technology.

description: Despite increasing concerns about the potential negative impacts of neonicotinoid insecticides on pollinator insect health in the regulatory community, public perceptions about the use of such pest management tools are mainly unknown. To assess U.S. consumers’ feedback to information linking neonicotinoid insecticides to pollinator health, the present study investigated consumers’ preferences for different neonicotinoid labels. Specifically, it analyzed the effect of negative and balanced pollinator related information treatments on consumers’ preferences for labels disclosing the absence or presence of neonicotinoids. The effects of the information treatments were asymmetric, with the negative information treatment having a more substantial impact on individual choices. Information treatments were more effective at influencing participants’ willingness to pay (WTP) for labels disclosing the absence of neonicotinoids, as opposed to labels disclosing the presence of neonicotinoids. Preexisting knowledge about neonicotinoid insecticides had a significant impact on how individuals responded to information treatments.

description: We attempt to visually classify the morphologies of 18190 molecular clouds, which are identified in the $^{12}$CO(1-0) spectral line data over $\sim$ 450 deg$^{2}$ of the second Galactic quadrant from the Milky Way Imaging Scroll Painting project (MWISP). Using the velocity-integrated intensity maps of the $^{12}$CO(1-0) emission, molecular clouds are first divided into unresolved and resolved ones. The resolved clouds are further classified as non-filaments or filaments. Among the 18190 molecular clouds, $\sim$ 25 $\%$ are unresolved, $\sim$ 64$\%$ are non-filaments, and $\sim$ 11$\%$ are filaments. In the terms of the integrated flux of $^{12}$CO(1-0) spectra of the whole 18190 molecular clouds, $\sim$ 90$\%$ are from filaments, $\sim$ 9$\%$ are from non-filaments, and the rest $\sim$ 1$\%$ are from unresolved sources. Although non-filaments are dominant in the number of the discrete molecular clouds, filaments are the main contributor of $^{12}$CO emission flux. We also present the number distributions of physical parameters of the molecular clouds in our catalog, including their angular sizes, velocity spans, peak intensities of $^{12}$CO(1-0) emission, and $^{12}$CO(1-0) total fluxes. We find that there is a systematic difference between the angular sizes of the non-filaments and filaments, with the filaments tending to have larger angular scales. The H$_{2}$ column densities of them are not significantly different. We also discuss the observational effects, such as those induced by the finite spatial resolution, beam dilution and line-of-sight projection, on the morphological classification of molecular clouds in our sample.

Electronic Structure and Optical Properties of Silicon Nanocrystals along their Aggregation Stages

Publisher: name: arXiv
Year: 2008
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: The structural control of silicon nanocrystals is an important technological problem. Typically a distribution of nanocrystal sizes and shapes emerges under the uncontrolled aggregation of smaller clusters. The aim of this computational study is to investigate the evolution of the nanocrystal electronic states and their optical properties throughout their aggregation stages. To realistically tackle such systems, an atomistic electronic structure tool is required that can accommodate about tens of thousand nanocrystal and embedding lattice atoms with very irregular shapes. For this purpose, a computationally-efficient pseudopotential-based electronic structure tool is developed that can handle realistic nanostructures based on the expansion of the wavefunction of the aggregate in terms of bulk Bloch bands of the constituent semiconductors. With this tool, the evolution of the electronic states as well as the polarization-dependent absorption spectra correlated with the oscillator strengths over their aggregation stages are traced. The low-lying aggregate nanocrystal states develop binding and anti-binding counterparts of the isolated states. Such information may become instrumental with the maturity of the controlled aggregation of these nanocrystals.

description: In a seminal paper Abadie and Imbens (2008) showed that the limiting variance of the classi- cal nearest neighbor matching estimator cannot be consistently estimated by a naive Efron-type bootstrap. Specifically, they show that the conditional variance of the Efron-type boostrap es- timator does not converge to the correct limit in expectation. In essence this is due to drawing with replacement such that original observations appear more than once in the bootstrap sample with positive probability even when the sample size becomes large. In the same paper, it is con- jectured that the limiting variance should be consistently estimable by an M-out-of-N bootstrap. Here, we prove that the conditional variance of an M-out-of-N-type bootstrap estimator does in- deed converge to the correct limit in expectation in the setting considered in Abadie and Imbens (2008). The key to the proof lies in the fact that asymptotically the M-out-of-N-type bootstrap sample does not contain any observations more than once with probability one. The finite sample performance of the M-out-of-N-type bootstrap is investigated in a simulation study of the DGP considered by Abadie and Imbens (2008).

description: In this paper, we propose a generalized natural inflation (GNI) model to study axion-like particle (ALP) inflation and dark matter (DM). GNI contains two additional parameters $(n_1, n_2)$ in comparison with the natural inflation, that make GNI more general. The $n_1$ build the connection between GNI and other ALP inflation model, $n_2$ controls the inflaton mass. After considering the cosmic microwave background and other cosmological observation limits, the model can realize small-field inflation with a wide mass range, and the ALP inflaton considering here can serve as the DM candidate for certain parameter spaces.

description: We present measurements of the luminosity and mass functions of low-mass stars constructed from a catalog of matched Sloan Digital Sky Survey (SDSS) and 2 Micron All Sky Survey (2MASS) detections. This photometric catalog contains more than 25,000 matched SDSS and 2MASS point sources spanning ~30 square degrees on the sky. We have obtained follow-up spectroscopy, complete to J=16, of more than 500 low mass dwarf candidates within a 1 square degree sub-sample, and thousands of additional dwarf candidates in the remaining 29 square degrees. This spectroscopic sample verifies that the photometric sample is complete, uncontaminated, and unbiased at the 99% level globally, and at the 95% level in each color range. We use this sample to derive the luminosity and mass functions of low-mass stars over nearly a decade in mass (0.7 M_sun > M_* > 0.1 M_sun). We find that the logarithmically binned mass function is best fit with an M_c=0.29 log-normal distribution, with a 90% confidence interval of M_c=0.20--0.50. These 90% confidence intervals correspond to linearly binned mass functions peaking between 0.27 M_sun and 0.12 M_sun, where the best fit MF turns over at 0.17 M_sun. A power law fit to the entire mass range sampled here, however, returns a best fit of alpha=1.1 (where the Salpeter slope is alpha = 2.35). These results agree well with most previous investigations, though differences in the analytic formalisms adopted to describe those mass functions can give the false impression of disagreement. Given the richness of modern-day astronomical datasets, we are entering the regime whereby stronger conclusions can be drawn by comparing the actual datapoints measured in different mass functions, rather than the results of analytic analyses that impose structure on the data a priori.

description: As reading on mobile devices is becoming more ubiquitous, content is consumed in shorter intervals and is punctuated by frequent interruptions. In this work, we explore the best way to mitigate the effects of reading interruptions on longer text passages. Our hypothesis is that short summaries of either previously read content (reviews) or upcoming content (previews) will help the reader re-engage with the reading task. Our target use case is for students who study using electronic textbooks and who are frequently mobile. We present a series of pilot studies that examine the benefits of different types of summaries and their locations, with respect to variations in text content and participant cohorts. We find that users prefer reviews after an interruption, but that previews shown after interruptions have a larger positive influence on comprehension. Our work is a first step towards smart reading applications that proactively provide text summaries to mitigate interruptions on the go.

Described frOm Australia in the genus Limothrips, this grass-living species has previOusly been knOwn Only frOm Australia where it is widespread in the warmer eastern parts Of that cOntinent (Pitkin 1978). It is here recOrded frOm China fOr the first time frOm the specimens listed belOw. A full descriptiOn Of the species was prOvided by MOund and MasumOtO (2009). AlthOugh similar in general appearance tO A. populi Zhang & TOng, with which it shares the light brOwn cOlOur Of bOdy and fOre wings, a lOng cOmb On tergite VIII, and similar bOdy sculpture, it is distinguished by the 8-segmented antennae, Ocellar setae pair III mOre widely separated (Fig. 1), tergite IX distinctly lOnger, and antennal segments III and IV variably yellOwish. The male listed belOw frOm Yunnan has the strOngly C-shaped sternal pOre plates (Fig. 2) that are typical Of sO many species in this genus, and tergite IX bears a pair Of shOrt stOut thOrn-like setae. The twO females frOm Tibet are the first knOwn micrOpterae Of this species. The fOre wings are shOrter than the thOrax width, the Ocelli are absent, and the fOur pOstOcular setae are in a transverse rOw, but in Other character states it is similar tO macrOpterae frOm Australia.

description: To precisely measure and evaluate X-ray generation and evolution in a hohlraum during an implosion process, we present a two-dimensional (2D) time- and space-resolved diagnostic method by combining a compressed ultrafast photography (CUP) system and a simplified version of space-resolving flux detector (SSRFD). Numerical experiment results showed that the reconstruction quality of the conventional CUP significantly improved owing to the addition of the external SSRFD, especially when a coded mask with a large pixel size was used in the CUP. Further, the performance of the CUP cooperation with the SSRFD was better than that of adding an external charge-coupled device or streak camera. Compared with existing ultrafast imaging techniques in laser fusion, the proposed method has a prominent advantage of measuring the 2D evolution of implosion by combining high temporal resolution of streak camera and high spatial resolution of SSRFD; moreover, it can provide guidance for designing diagnostic experiments in laser fusion research.

description: The aim of this study is to explore the concept of value creating meetings that connect agri-food firms with other crucial actors with whom they can collaborate or co-innovate, and related to this, examine the role of innovation intermediary organisations in the forming of such value creating meetings. The research design involves three case studies of intermediary organisations, within the agri-food sector in Sweden, each with an adherent case of a value creating meeting. The method comprises data collected through documents, interviews and insider accounts. The findings include the notion that three factors – problem, professionals and platform – are important to combine in order to facilitate value creation. We also show that intermediaries play an important role in the value creation process and that this process could be summarised into four steps: problem recognition, contact creation, dialogue facilitation and value creation. We elaborate on the role of innovation intermediaries, give examples of how value creating meetings could be arranged and what such meetings can lead to in case of outcome. Practical implications for policy makers and agri-food business firms include that intermediary organisations can play an important bridging role in a complex and fragmented context, offering contacts, networks and value creating meetings for targeted actors. Intermediary organisations need to focus on forming value creating meetings, work actively across sectoral boundaries, and allocate adequate resources for mediating efforts.
Imprint of Distortions in the Oort Cloud on the CMB Anisotropies

description: We study the effect of a close encounter of a passing star on the shape of the inner Oort Cloud, using the impulse approximation. The deviation of the perturbed Oort Cloud from sphericity adds angular fluctuations to the brightness of the Cosmic Microwave Background (CMB) due to thermal emission by the comets. An encounter with a solar-mass star at an impact parameter of $1750 \au$, as expected based on the abundance and velocity dispersion of stars in the solar neighborhood, leads to a quadrupole moment in the square of the fractional CMB intensity fluctuation of $C_2 = 4.5 \times 10^{-15}, 6.7 \times 10^{-12}, 1.1 \times 10^{-9}$ at $ν= 30, 353, 545 \GHz$ (these being the frequency bands of the upcoming Planck satellite). We also quantify the quadrupole spectral distortions produced by the Scattered Disc, which will exist regardless of any perturbation and the subsequent shape of the Oort Cloud. For comparison, the square fractional temperature fluctuation quadrupole moment predicted by the current cosmological model is $C_2 = 1.76 \times 10^{-10}$, which corresponds to fluctuations in the CMB intensity of $C_2 = 2.9 \times 10^{-10}, 6.8 \times 10^{-9}, 1.6 \times 10^{-8}$ at $ν= 30, 353, 545 \GHz$. Finally, we discuss how a measurement of the anisotropic spectral distortions could be used to constrain the trajectory of the closest stellar fly-by.

Breakdown of quantum-classical correspondence and dynamical generation of entanglement

description: The {\it exchange} interaction arising from the particle indistinguishability is of central importance to physics of many-particle quantum systems. Here we study analytically the dynamical generation of quantum entanglement induced by this interaction in an isolated system, namely, an ideal Fermi gas confined in a chaotic cavity, which evolves unitarily from a non-Gaussian pure state. We find that the breakdown of the quantum-classical correspondence of particle motion, via dramatically changing the spatial structure of many-body wavefunction, leads to profound changes of the entanglement structure. Furthermore, for a class of initial states, such change leads to the approach to thermal equilibrium everywhere in the cavity, with the well-known Ehrenfest time in quantum chaos as the thermalization time. Specifically, the quantum expectation values of various correlation functions at different spatial scales are all determined by the Fermi-Dirac distribution. In addition, by using the reduced density matrix (RDM) and the entanglement entropy (EE) as local probes, we find that the gas inside a subsystem is at equilibrium with that outside, and its thermal entropy is the EE, even though the whole system is in a pure state. As a by-product of this work, we provide an analytical solution supporting an important conjecture on thermalization, made and numerically studied by Garrison and Grover in: Phys. Rev. X \textbf{8}, 021026 (2018), and strengthen its statement.

description: Personalized chatbots focus on endowing chatbots with a consistent personality to behave like real users, give more informative responses, and further act as personal assistants. Existing personalized approaches tried to incorporate several text descriptions as explicit user profiles. However, the acquisition of such explicit profiles is expensive and time-consuming, thus being impractical for large-scale real-world applications. Moreover, the restricted predefined profile neglects the language behavior of a real user and cannot be automatically updated together with the change of user interests. In this paper, we propose to learn implicit user profiles automatically from large-scale user dialogue history for building personalized chatbots. Specifically, leveraging the benefits of Transformer on language understanding, we train a personalized language model to construct a general user profile from the user's historical responses. To highlight the relevant historical responses to the input post, we further establish a key-value memory network of historical post-response pairs, and build a dynamic post-aware user profile. The dynamic profile mainly describes what and how the user has responded to similar posts in history. To explicitly utilize users' frequently used words, we design a personalized decoder to fuse two decoding strategies, including generating a word from the generic vocabulary and copying one word from the user's personalized vocabulary. Experiments on two real-world datasets show the significant improvement of our model compared with existing methods. Our code is available at https://github.com/zhengyima/DHAP

description: In small scale societies and developing nations, agrifood systems tend to be structurally less complex than in developed nations but have a complexity introduced in the form of strict social and cultural mores which both help to formulate decision making and create governance mechanisms. Informality in the economic underpinning of these agrifood systems has worked for these small-scale societies for thousands of years but the question is whether and how they can remain sustainable in the fast moving change situation of today’s global business. In this paper we discuss sustainability from a modified Triple Bottom Line perspective and analyse data from horticultural product chain studies in two Pacific Island countries to investigate the informal framework of sustainability in these systems. We use the theoretical paradigm of theatre performance (frontstage:backstage) to understand how a ‘habitus of informality’ is both a threat and an opportunity to sustainability in these small scale, yet complex, systems.
