description: Shared dynamics models are important for capturing the complexity and variability inherent in Human-Robot Interaction (HRI). Therefore, learning such shared dynamics models can enhance coordination and adaptability to enable successful reactive interactions with a human partner. In this work, we propose a novel approach for learning a shared latent space representation for HRIs from demonstrations in a Mixture of Experts fashion for reactively generating robot actions from human observations. We train a Variational Autoencoder (VAE) to learn robot motions regularized using an informative latent space prior that captures the multimodality of the human observations via a Mixture Density Network (MDN). We show how our formulation derives from a Gaussian Mixture Regression formulation that is typically used approaches for learning HRI from demonstrations such as using an HMM/GMM for learning a joint distribution over the actions of the human and the robot. We further incorporate an additional regularization to prevent "mode collapse", a common phenomenon when using latent space mixture models with VAEs. We find that our approach of using an informative MDN prior from human observations for a VAE generates more accurate robot motions compared to previous HMM-based or recurrent approaches of learning shared latent representations, which we validate on various HRI datasets involving interactions such as handshakes, fistbumps, waving, and handovers. Further experiments in a real-world human-to-robot handover scenario show the efficacy of our approach for generating successful interactions with four different human interaction partners.

description: A theoretical study is performed for the excitation of a single atom localized in the center of twisted light modes. Here we present the explicit dependence of excitation rates on critical parameters, such as the polarization of light, its orbital angular momentum projection, and the orientation of its propagation axis with respect to the atomic quantization axis. The effect of a spatial spread of the atom is also considered in detail. The expressions for transition rates obtained in this work can be used for any atom of arbitrary electronic configuration. For definiteness we apply them to the specific case of $^{2}S_{1/2} (F=0) \rightarrow\; ^{2}F_{7/2} (F=3, M=0)$ electric octupole (E3) transition in $^{171}$Yb$^{+}$ ion. Our analytical and numerical results are suitable for the analysis and planning of future experiments on the excitation of electric-dipole-forbidden transitions by twisted light modes in optical atomic clocks.
Forward and midrapidity like-particle ratios from p+p collisions at sqrt(s)=200 GeV

description: We present a measurement of pi-π+, K-/K+ and pbar/p from p+p collisions at sqrt(s) = 20 0GeV over the rapidity range 0 2.0. The pbar/p ratio is very similar for p+p and 20% central Au+Au collisions at all rapidities. In the fragmentation region the three ratios seem to be independent of beam energy when viewed from the rest frame of one of the protons. Theoretical models based on quark-diquark breaking mechanisms overestimate the pbar/p ratio up to y ~< 3. Including additional mechanisms for baryon number transport such as baryon junctions leads to a better description of the data.

description: According to certain recent investigations French consumers are increasingly sensitive to the regional and organic origin of their food purchases. The objective of this article is to identify the principal predictive variables of the purchasing intention of regional organic products. For that a quantitative investigation (n = 917) was carried out on the basis of the theory of planned behaviour. Considering the exploratory character of this research, the investigation integrates, in the same questionnaire, three models of the theory on a) the purchasing intention of regional products b) the purchasing intention of organic products and c) the purchasing intention of regional organic products. The analysis of the purchasing intentions of regional organic products shows the prevalence of the altruistic motivations (benefits for the environment and for the local economy) contrary to the models on the regional or organic product purchase in which the prevalent motivations are of personal order.

description: A facile method to produce few-layer graphene (FLG) nanosheets is developed using protein-assisted mechanical exfoliation. The predominant shear forces that are generated in a planetary ball mill facilitate the exfoliation of graphene layers from graphite flakes. The process employs a commonly known protein, bovine serum albumin (BSA), which not only acts as an effective exfoliation agent but also provide stability by preventing restacking of the graphene layers. The latter is demonstrated by the excellent long-term dispersibility of exfoliated graphene in an aqueous BSA solution, which exemplifies a common biological medium. The development of such potentially scalable and toxin-free methods is critical for producing cost-effective biocompatible graphene, enabling numerous possible biomedical and biological applications. A methodical study was performed to identify the effect of time and varying concentrations of BSA towards graphene exfoliation. The fabricated product has been characterized using Raman spectroscopy, powder X-Ray diffraction, transmission electron microscopy and scanning electron microscopy. The BSA-FLG dispersion was then placed in media containing Astrocyte cells to check for cytotoxicity. It was found that lower concentrations of BSA-FLG dispersion had only minute cytotoxic effects on the Astrocyte cells.
Bridging the two solitudes : translated French-Canadian children’s literature from 1900 to 2004

description: In Canada, where only 18% of the population is bilingual in English and French, translation should be an essential part of Canadian literature, and research on translation should be an essential part of research on Canadian literature. In the field of Canadian children’s literature, however, research on translation has been minimal. There has not been a significant, in-depth overview of translated Canadian children’s literature since 1987, and since then, much has changed. This study updates the current knowledge of Canadian children’s books that have been translated from French into English and published in Canada from 1900 to 2004. It compiles a comprehensive list of the translated French-Canadian children’s books held by Library and Archives Canada and analyses characteristics of the books in order to identify historical and contemporary trends in translated French-Canadian children’s literature. The study identifies 678 translations, observing that the annual number of translations has increased fairly steadily since 1900, peaking in 2001 and decreasing dramatically since then. The majority of translations are picture books and illustrated nonfiction, with other genres like novels, drama, and short stories figuring much less prominently, and poetry not being translated at all. Series have played a significant role in translation, particularly the Caillou series, which makes up over 12% of the translations in this study. Overall, Canadian publishers have tended to be cautious, publishing well-known French-Canadian authors, illustrators, and series almost exclusively, rather than taking risks on unfamiliar authors or challenging themes. Translations by English-Canadian publishers, who had historically published the majority of English translations, have decreased steadily since 1988, while translations by Quebec publishers increased from the 1970s to 2001, when they also began to decrease. The relatively low popularity of translated books in the English language market, coupled with Canadian publishers’ increasing reliance on the American market, as well as inconsistent government support for translations, has left French-Canadian children’s literature in a state of crisis. As a result, the number and diversity of translated French-Canadian children’s books are limited; this is a particular concern for anglophone Canadians, who have no other way to experience French-Canadian children’s literature except in translation.

description: Observations of the gravitational microlensing event MOA 2003-BLG-32/OGLE 2003-BLG-219 are presented for which the peak magnification was over 500, the highest yet reported. Continuous observations around the peak enabled a sensitive search for planets orbiting the lens star. No planets were detected. Planets 1.3 times heavier than Earth were excluded from more than 50 % of the projected annular region from approximately 2.3 to 3.6 astronomical units surrounding the lens star, Uranus-mass planets from 0.9 to 8.7 astronomical units, and planets 1.3 times heavier than Saturn from 0.2 to 60 astronomical units. These are the largest regions of sensitivity yet achieved in searches for extrasolar planets orbiting any star.

description: Context. As a novel coronavirus swept the world in early 2020, thousands of software developers began working from home. Many did so on short notice, under difficult and stressful conditions. Objective. This study investigates the effects of the pandemic on developers' wellbeing and productivity. Method. A questionnaire survey was created mainly from existing, validated scales and translated into 12 languages. The data was analyzed using non-parametric inferential statistics and structural equation modeling. Results. The questionnaire received 2225 usable responses from 53 countries. Factor analysis supported the validity of the scales and the structural model achieved a good fit (CFI = 0.961, RMSEA = 0.051, SRMR = 0.067). Confirmatory results include: (1) the pandemic has had a negative effect on developers' wellbeing and productivity; (2) productivity and wellbeing are closely related; (3) disaster preparedness, fear related to the pandemic and home office ergonomics all affect wellbeing or productivity. Exploratory analysis suggests that: (1) women, parents and people with disabilities may be disproportionately affected; (2) different people need different kinds of support. Conclusions. To improve employee productivity, software companies should focus on maximizing employee wellbeing and improving the ergonomics of employees' home offices. Women, parents and disabled persons may require extra support.

description: We present results from the first recorded stellar occultation by the large trans-Neptunian object (174567) Varda that was observed on September 10$^{\rm th}$, 2018. Varda belongs to the high-inclination dynamically excited population, and has a satellite, Ilmarë, which is half the size of Varda. We determine the size and albedo of Varda and constrain its 3D shape and density. Thirteen different sites in the USA monitored the event, five of which detected an occultation by the main body. A best-fitting ellipse to the occultation chords provides the instantaneous limb of the body, from which the geometric albedo is computed. The size and shape of Varda are evaluated, and its bulk density is constrained, using Varda's mass known from previous works. The best-fitting elliptical limb has semi-major (equatorial) axis of $(383 \pm 3)$km and an apparent oblateness $0.066\pm0.047$ corresponding to an apparent area-equivalent radius $R'_{\rm equiv}= (370\pm7)$km and geometric albedo $p_v=0.099\pm 0.002 $ assuming a visual absolute magnitude $H_V=3.81\pm0.01$. Using three possible rotational periods for the body (4.76h, 5.91h, and 7.87h), we derive corresponding MacLaurin solutions. Furthermore, given the low-amplitude ($0.06\pm0.01$) mag of the single-peaked rotational light-curve for the aforementioned periods, we consider the double periods. For the 5.91h period (the most probable) and its double (11.82h), we find bulk densities and true oblateness of $ρ=(1.78\pm0.06)$ g cm$^{-3}$, $ε=0.235\pm0.050$ and $ρ=(1.23\pm0.04)$ g cm$^{-3}$, $ε=0.080\pm0.049$. However, it must be noted that the other solutions cannot be excluded just yet.

description: A national labelling scheme recognising the environmental quality for seafood products is still expected in France. Announced by the Grenelle law of 2009, the by-law setting a public ecolabel has only been adopted on January 27th 2012. In the meantime, several private initiatives have already emerged. In this paper, the factors influencing the consumers’ perceptions for seafood eco-labels are analysed on the basis of a survey carried out on more than 900 consumers. Our results show a higher preference from young and educated citizens. The production process and marketing characteristics such as the attention paid to the geographical origin of seafood products, their farmed or wild origin, the fishing technique and the exploitation level of natural stocks, strengthen the preference for eco-labels.

The measured branching fraction is B(B+ -> proton Lambdabar gamma) = (2.16 ^{+0.58}_{-0.53} +- 0.20) times 10^{-6}. A search for B+ -> proton Sigmabar gamma yields no significant signal, so we set a 90% confidence-level upper limit on the branching fraction of B(B+ -> proton Sigmabar gamma) < 3.3 times 10^{-6}.

description: ABSTRACT The Cuban Almendares River flows towards northwest, intersecting the neighborhoods Miramar and El Vedado in Havana. The river serves as one of the main fresh water supplier for the city, and the Almendares Aquifer arm is still covering the majority of Havana-s water demand today. The adjacent urban area alongside this waterfront has been a scene of different social, urban and architectural developments. In addition to informal settlements and several abandoned factories, the area suffers from severe industrial and urban waste dumping. Moreover, frequent flooding, especially in the northern part of the river constitutes a severe danger. The entire area lacks accessible public space, recreational zones and sufficient housing. Another issue is inaccessibility along the waterfront. Fences, storage buildings, small industries and other physical barriers separate the waterfront from the surrounding urban area. The aim of this masters thesis was to analyse the urban potential, and to suggest a strategy for revitalizing, linking and incorporating the adjacent urban areas with the Almendares Riverfront. Here, I will present ideas and concepts for different types of structural interventions to facilitate new impulses for the local urban and regional development of this district.

description: We construct the colliding plane wave solutions in the higher-dimensional gravity theory with fluxes and dilaton, with a more general ansatz on the metric. We consider two classes of solutions to the equations of motions and after imposing the junction conditions we find that they are all physically acceptable. In particular, we manage to obtain the higher-dimensional Bell-Szekeres solutions in the Maxwell-Einstein gravity theory, and the flux-CPW solutions in the eleven-dimensional supergravity theory. All the solutions have been shown to develop the late time curvature singularity.

DY Pegasi: An SX Phoenicis Star in a Binary System with an Evolved Companion

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: In this work, the photometric data from the American Association of Variable Star Observers are collected and analyzed on the SX Phoenicis star DY Pegasi (DY Peg). From the frequency analysis, we get three independent frequencies: $f_0 = 13.71249\ \rm{c\ days^{-1}}$, $f_1 = 17.7000\ \rm{c\ days^{-1}}$, and $f_2 =18.138\ \rm{c\ days^{-1}}$, in which $f_0$ and $f_1$ are the radial fundamental and first overtone mode, respectively, while $f_2$ is detected for the first time and should belong to a nonradial mode. The $O-C$ diagram of the times of maximum light shows that DY Peg has a period change rate $(1/P_0)(\mathrm{d} P_0/\mathrm{d} t) = -(5.87 \pm 0.03) \times 10^{-8} \ \mathrm{yr^{-1}}$ for its fundamental pulsation mode, and should belong to a binary system that has an orbital period $P_{\mathrm{orb}} = 15425.0 \pm 205.7 \ \mathrm{days}$. Based on the spectroscopic information, single star evolutionary models are constructed to fit the observed frequencies. However, some important parameters of the fitted models are not consistent with that from observations. Combing with the information from observation and theoretical calculation, we conclude that DY Peg should be an SX Phoenicis star in a binary system and accreting mass from a dust disk, which was the residue of its evolved companion (most probably a hot white dwarf at the present stage) produced in the asymptotic giant branch phase. Further observations are needed to confirm this inference, and it might be potentially a universal formation mechanism and evolutionary history for SX Phoenicis stars.

By making use of numerical calculation and analytical treatment, the conditions under which HA works well can be precisely presented to control the parameters implementing the two-qubit quantum logical gate through the couplings to the large junction with harmonic oscillator (HO) Hamiltonian.

description: This paper aims to understand the disparity of the estimations of farmer’s celibacy through many French scientific publications. This inquiry has been focused on the statistical and sociological construction of celibacy and agriculture. The differences in the definition of farmer’s population, statistical unit, reference person, or celibacy’s indicators are studied in various statistical surveys. Finally this paper suggests an estimation of farmer’s celibacy and a comparison with other professions.

description: We show that lattice results on four flavor QCD at nonzero temperature and baryon density compare well with the hadron resonance gas model up to T approx. 0.95 Tc, and approach a free field behaviour with a reduced effective number of flavor for T \ge 1.5 Tc. Chiral symmetry and confinement are interrelated, and we note analogies between the critical line of QCD and that of simple models with the same global symmetries.

description: Numerical simulations of particle acceleration in magnetized turbulence have recently observed powerlaw spectra where pile-up distributions are rather expected. We interpret this as evidence for particle segregation based on acceleration rate, which is likely related to a non-trivial dependence of the efficacy of acceleration on phase space variables other than the momentum. We describe the corresponding transport in momentum space using continuous-time random walks, in which the time between two consecutive momentum jumps becomes a random variable. We show that powerlaws indeed emerge when the experimental (simulation) timescale does not encompass the full extent of the distribution of waiting times. We provide analytical solutions, which reproduce dedicated numerical Monte Carlo realizations of the stochastic process, as well as analytical approximations. Our results can be readily extrapolated for applications to astrophysical phenomenology.

Corona-Test für die Gesellschaft
Creators: name: Henkel, Anna
Publisher: name: Soziologie und Nachhaltigkeit
Year: 2020

description: Pandemiegefahr, globale Veränderung des Klimas oder Verschmutzung der Ozeane – bis vor kurzem wurden Probleme wie diese aufgrund ihrer zeitlichen und räumlichen Ferne gleichermaßen als wenig dringlich erlebt. Mit Corona ist ein derart Fernes zu einer sich plötzlich massiv aufdrängenden Gefährdung geworden. Corona lässt sich daher aus Perspektive einer materialitätstheoretisch erweiterten Systemtheorie als Stresstest für die Gesellschaft betrachten: Zunächst wird ausgeführt, wie Gesellschaft generell und wie speziell die funktional differenzierte Gesellschaft zu dem steht, was für sie die Außenwelt ist. Darauf beruht eine Analyse der gesellschaftlichen Reaktion auf Corona, an die eine Diskussion der Konsequenzen aus dieser nahen für aktuell noch ferne Gefährdungen anschließt. Corona als Test betrachtet zeigt dann drei zentrale Probleme, aus denen für den Umgang mit unter dem Stichwort Nachhaltigkeit diskutierten Gefährdungen Schlussfolgerungen gezogen werden können. Erforderlich sind demnach die Absicherung funktionaler Differenzierung, die Berücksichtigung von Rückkopplungsverhältnissen und die Einbeziehung „autonomer Immaterialität“ als zusätzlicher Form struktureller Kopplung. The danger of a pandemic, global climate change oder polution of the ozeans – until lately problems such as these were equally perceived as rather far away and accordingly non-pressing challenges. With Corona, something far suddenly become urgently close. From the perspective of a materiality-informed theory of social systems, Corona can be observed as a stress-test for society: After the introduction, the relationship of society generally and the functionally differentiated society in particular to it’s outer sphere is discussed. This perspective is applied in the following analysis of the societal reactions to corona. A discussion of consequences of this suddenly close to still far-away dangers closes the paper. Corona as a test hints to three relevant problems that can be learned from for dealing with challenges discussed under the label of sustainability. Required are the protection of functional differentiation, the closer consideration of back-coupling and the admission to „autonomous immateriality“ as a further form of sturctual coupling.

Ward identities and Chiral anomaly in the Luttinger liquid

Year: 2004

description: Systems of interacting non relativistic fermions in $d=1$, as well as spin chains or interacting bidimensional Ising models, verify an hidden approximate Gauge invariance which can be used to derive suitable Ward identities. Despite the presence of corrections and anomalies, such Ward identities can be implemented in a Renormalization Group approach and used to exploit nontrivial cancellations which allow to control the flow of the running coupling constants; in particular this is achieved combining Ward identities, Dyson equations and suitable correction identities for the extra terms appearing in the Ward identities, due to the presence of cutoffs breaking the local gauge symmetry. The correlations can be computed and show a Luttinger liquid behavior characterized by non universal critical indices, so that the general Luttinger liquid construction for one dimensional systems is completed without any use of exact solutions. The ultraviolet cutoff can be removed and a Quantum Field Theory corresponding to the Thirring model is also constructed.
Requirements for very high temperature Kohn-Sham density functional simulations and how to bypass them

description: In high temperature density functional theory simulations (from tens of eV to keV) the total number of Kohn-Sham orbitals is a critical quantity to get accurate results. To establish the relationship between the number of orbitals and the level of occupation of the highest orbital, we derived a model based on the electron gas properties at finite temperature. This model predicts the total number of orbitals required to reach a given level of occupation and thus a stipulated precision. Levels of occupation as low as 10-4, and below, must be considered to get converged results better than 1%, making high temperature simulations very time consuming beyond a few tens of eV. After assessing the predictions of the model against previous results and ABINIT minimizations, we show how the extended FPMD method of Zhang et al. [PoP 23 042707, 2016] allows to bypass these strong constraints on the number of orbitals at high temperature.

description: The crisis of avian influenza occurred in Vietnam in late 2003 has affected the organization of the local poultry value chain. This crisis has resulted in an alliance between the Vietnamese government and agro-industrial sector considered more capable than the traditional one, to meet the requirements of “biosecurity”. In the short term, this alliance has allowed agro-industrial groups to develop and to take the control of a growing number of activities in the avian chain through a process of vertical integration (animal raising slaughtering, retailing) and, to a lesser extent, through contracting with farmers. This movement was slowed down once the crisis abated, since consumers turned back to traditional products, eliminating thus the less competitive groups. Thus, in the medium term, instead of benefiting the industrial sector at the expense of the traditional one, as one could expect, this crisis allowed a small number of agro-industrial groups, and especially international groups (we discuss in more detail the Asian group Charoen Pokphand) to establish their position in a market certainly promising, in the long term, despite its many hazards.

title: Testing and Analysis of a Computational Model of Human Rhythm Perception
Creators: name: Angelis, Vassilis
Publisher: name: The Open University
Year: 2014

description: This thesis presents an original methodology, as detailed below, applied to the testing of an existing computational model of human rhythm perception. Since the computational model instantiates neural resonance theory (Large and Snyder,2009), the thesis also tests that theory. Neural resonance theory is a key target for testing since, as contrasted with many other theories of human rhythm perception, it has relatively strong physiological plausibility. Rather than simply matching overt features of human rhythm perception, neural resonance theory shows how these features might plausibly emerge from low-level properties of interacting neurons. The thesis tests the theory using several distinct research methods. The model stood up well to each family of tests, subject to limitations that are analysed in detail. Firstly, the responses of the model to several types of polyrhythmic stimuli were compared with existing empirical data on human responses regarding beat identiﬁcation to the same stimuli, at a variety of tempi. Polyrhythmic stimuli closely resemble real life complex rhythmical stimuli such as music, and were used for the ﬁrst time to test the model. It was found that the set of categories of response predicted by the model matched human behaviour. Secondly, the model was systematically analysed by exploring the degree of dependence of its behaviour on the values of its parameters (sensitivity analysis). The behaviour of the model was found to retain consistency in the face of systematic numerical manipulation of its parameters. Thirdly, the behaviour of the model was compared to that of related models. In particular, the focal computational model, which balances physiological plausibility with mathematical convenience, was compared with other models that relate more directly to brain physiology. In each case, all relevant behaviours were found to be closely in line. Lastly, the outputs of the model under polyrhythmic stimuli were analysed to make new testable predictions about previously unobserved human behaviour regarding the time it takes for people to perceive beat in polyrhythms. These predictions led to the design and conduction of new human experimental studies. It was found that the model had successfully predicted previously unobserved aspects of human behaviour, more speciﬁcally it predicted the timescale within which people start to perceive beat in a given polyrhythmic stimulus.

Nuclear contacts of unstable nuclei

description: Nuclear contact is a key quantity to describe the nucleon-nucleon short-range correlations (SRCs). While they have been determined by electron scattering experiments for selected stable nuclei, nuclear contacts are largely unknown for unstable nuclei. In this work, we study nuclear contacts for a number of nuclei in the vicinity of the doubly magic $^{132}$Sn from the theoretical perspective, with special emphasis on unstable nuclei. We find that the proton-proton contact generally gets suppressed by the excess neutrons for the Sn isotopes, resembling the suppression of $α$-cluster formation reported recently for the same isotopic chain [J. Tanaka $\textit{et al}.$, Science $\textbf{371}$, 260 (2021)]. This indicates a hidden universal aspect of SRCs and $α$ clustering, two different kinds of nuclear correlations. Meanwhile, a linear relation is found between the proton-proton contact and the proton number for the $N=82$ isotones. Our results can be helpful for future experimental studies of SRCs in unstable nuclei at advanced facilities worldwide.

description: In the wake of the anti-GMO struggles of the nineties and the toughening of seed laws, the 2000s saw the emergence of a farmers’ movement dedicated to the reappropriation of seeds. Spanning over a 10 year period, the paper looks at the movement’s drivers and its transformations. The reappropriation by a group of farmers of seeds takes root in a critical discourse towards agricultural modernity, which translates into 3 dimensions – the rejection of modern plant breeding techniques, opposition to the subaltern position of farmers, denunciation of the instrumental relationship between industrial farming and nature. Yet the movement has also enriched itself and been fashioned by a direct engagement with plants. This case study contributes to a better understanding of the ongoing ecologisation of agriculture. Moreover it provides a comprehensive illustration of a protest movement that is altered by the very object that it contributes to shape.
