description: Generalizing the graded commutator in superalgebras, we propose a new bracket operation on the space of graded operators with an involution. We study properties of this operation and show that the Lax representation of the two-dimensional N=(1|1) supersymmetric Toda lattice hierarchy can be realized via the generalized bracket operation; this is important in constructing the semiclassical (continuum) limit of this hierarchy. We construct the continuum limit of the N=(1|1) Toda lattice hierarchy, the dispersionless N=(1|1) Toda hierarchy. In this limit, we obtain the Lax representation, with the generalized graded bracket becoming the corresponding Poisson bracket on the graded phase superspace. We find bosonic symmetries of the dispersionless N=(1|1) supersymmetric Toda equation.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We report here an alternate redesigned five-step synthesis of 2,6-diacetamido-4-formylpyridine. The method described here is more convenient where this aldehyde is prepared in commercially viable quantities from simple and easy-to-use reagents and is a key compound required to prepare 5,10,15,20-Tetrakis(3,5-diacetamido-4-pyridyl)porphyrin (I). This porphyrin can be used as an excellent building block for the construction of supramolecular assemblies and is an interesting compound to study the design, principles, and photonic properties such as the extent of electron and energy transfer.

description: The effect of edge and corner diffusions on the morphology and on the density of islands nucleated irreversibly on a flat substrate surface is studied. Without edge and corner diffusion, islands are fractal. As an edge diffusion constant $D_e$ increases, islands tend to take a cross shape with four needles in the $< 10 >$ direction. Additional corner diffusion with a diffusion constant $D_c$ yields square islands. When $D_e$ is small relative to the surface diffusion constant $D_s$, the square corner shows the Berg instability to produce hopper growth in the $<11>$ direction. The corner diffusion influences the island number density $n$. At a deposition flux $F$ with a small $D_c$, mainly monomers are mobile and $n \propto (F/D_s)^{1/3}$. At large $D_c$, dimers and trimers are also mobile and $n \propto F^{3/7} D_s^{-5/21} D_c^{-4/21}$. The $F$ dependence is in good agreement to the rate equation analysis, but the dependence on $D_c$ cannot be explained by the theory.

description: Ireland’s dairy sector is characterised by pastoral spring-calving systems and seasonal milk production at national level. This production seasonality initiates various implications at processor level, such as poor plant capacity utilisation off-peak season or a requirement for seasonal labour, which impose extra costs on the processor and limit their options as to which markets can be serviced. An optimisation model was developed to analyse the impact of production seasonality on the Irish dairy processing industry regarding processor gross surplus (Surplus), costs of milk collection and handling, processing, product storage and labour as well as on product mix, plant and labour capacity utilisation and the marginal producer milk price (MPMP). Three scenarios with differing milk intake curves were examined whereby it was found that a flatter intake pattern incurred less variation in the MPMP and capacity utilisation in addition to a higher Surplus and a larger proportion of more profitable products in the product mix vis-à-vis seasonal patterns. As expected, these results suggest that a producer supplying milk in line with a nationally seasonal production pattern receives lower milk payments since the seasonality-related costs are fed back from the processor to the producer via a lower producer milk price.
Expected Qualitative Utility Maximization

subject: I.2.3

description: A model for decision making that generalizes Expected Utility Maximization is presented. This model, Expected Qualitative Utility Maximization, encompasses the Maximin criterion. It relaxes both the Independence and the Continuity postulates. Its main ingredient is the definition of a qualitative order on nonstandard models of the real numbers and the consideration of nonstandard utilities. Expected Qualitative Utility Maximization is characterized by an original weakening of von Neumann-Morgenstern's postulates. Subjective probabilities may be defined from those weakened postulates, as Anscombe and Aumann did from the original postulates. Subjective probabilities are numbers, not matrices as in the Subjective Expected Lexicographic Utility approach.

description: In this paper we attempt to identify and model factors associated with medical doctors' county-level location decisions. Our goal is to determine whether public policy levers and private incentives exist which can be manipulated to increase the availability of doctors in rural areas. After developing a formal model of medical doctors' location decisions, we use 1989 county-level data on numbers of doctors from the Area Resource File (ARP) to estimate econometric equations at the county-level for the entire U.S. predicting the number of doctors per capita. The data on medical doctors are complemented with ARP data on causes-of-death in 1989, data from the 1990 U.S. Census of Population, and the USDA's rural-urban adjacency or continuum (Beale) code, as well as various state-level variables.

description: A jump process for the positions of interacting quantum particles on a lattice, with time-dependent transition rates governed by the state vector, was first considered by J.S. Bell. We review this process and its continuum variants involving ``minimal'' jump rates, describing particles as they get created, move, and get annihilated. In particular, we sketch a recent proof of global existence of Bell's process. As an outlook, we suggest how methods of this proof could be applied to similar global existence questions, and underline the particular usefulness of minimal jump rates on manifolds with boundaries.

description: We propose two schemes for achieving continuous and complete orbital angular momentum tuning using a simple device based on a phase only parallel aligned liquid crystal on silicon display, where the tuning is managed by changing the input beam state of polarization. We use an optical tweezers toolbox to simulate the optical force field of the tuned beams applied to dielectric spherical particles in order to prove the applicability of the method.

description: Risk management is gaining importance in agriculture. In addition to traditional instruments, new risk management instruments are increasingly being proposed. These proposals include the rent adjustment clauses (RACs), which seem to be an unusual instrument at first sight. In contrast with conventional instruments, RACs intentionally allow fixed-cost ‘rent payments’ to fluctuate. We investigate the whole-farm risk reduction potential of different types of RACs via a historical simulation. The change in standard deviation and the value at risk (VaR) of the total gross margin (TGM) measure risk reduction potential. Our results revealed that RACs contribute to farm risk management. However, the trade-off between moral hazard and basis risk must be considered. Our proposal of weather index-based RAC seems to be a ‘good compromise’: the problem of moral hazard is completely eliminated by objectively measuring weather data. At the same time, the risk reduction potential of precipitation-based clauses, for example, is comparatively high.

description: Nonlinear conduction (NLC) of the two-leg spin ladder, Sr$_{14-x}$Ca$_x$Cu$_{24}$O$_{41}$, was investigated for the $x$=0, 1 and 12 materials . Although insulating materials ($x$=0 and 1) exibited the NLC both in the ladder- and rung directions, the NLC in the ladder direction of the $x$=0-material was found to be very special. We considered this to be due to the sliding motion of the charge ordered state, which was responsible for the resonance at microwave frequencies. We discussed possible candidates for the charge ordered state responsible for the NLC, including Wigner crystal in quasi one dimension (4$k_F$-CDW).

description: The New Zealand Government is a signatory of the Kyoto Protocol which provides incentive for it to reduce its total greenhouse gas emissions (GHG). The sheep industry is a significant contributor to the total GHG in New Zealand. It also has widespread use of selection index technology which could be a potential GHG mitigation tool. This paper provides an assessment of the potential for New Zealand sheep farmers to reduce GHG using selection indices. Trait weightings were altered in novel indices to facilitate greater reductions in GHG. These were compared to a conventional farm profit maximising index. Selection of sheep using the farm profit maximising index reduced GHG output in kilograms of carbon dioxide equivalent units (kg CO2e) per kilogram of lamb carcase weight (kg cwt) by 0.59% of total methane and nitrous oxide emissions per annum (pa). Novel ‘Dual Purpose Environment’ indices (DPE) were developed to provide greater GHG reductions in kg CO2e/kg cwt. A range of carbon prices were incorporated into the DPE. The study showed 96.6% of the potential farm profit (excluding emissions costs) and 69.8% of potential kg CO2e/kg cwt improvements could be obtained using a carbon price of NZ$100/tonne CO2e in the DPE. The corresponding figures for NZ$25/t CO2e were 99.8% and 56%. The carbon price used in the DPE therefore influenced the trade-off between progress in traits which reduce GHG in kg CO2e/kg cwt and those that improve farm profitability. Selection indices are an option for farmers to reduce GHG in kg CO2e/kg cwt in New Zealand sheep. However, farmers will need to consider the trade-off between improving traits which contribute to farm profit and those that reduce GHG.

description: The incidence of diseases and accidents that lead to death is not uniform throughout the U.S. but rather varies widely among different regions. This study uses county-level data on numbers and causes of death for the entire U.S. in an effort to link these causes of death to various county-level social and economic variables. Examples of causes of death for which county-level data are available include cancer, heart disease, infectious diseases, motor vehicle accidents, and other causes such as non-motor vehicle accidents and drownings. A series of econometric equations is specified. Each equation includes socioeconomic and demographic variables thought to be related to the particular cause of death. For example, infectious diseases may be more prevalent in areas with high population densities; the incidences of cancer and heart disease may be age-related. Computer cartography (G!S) is employed to generate county-level maps illustrating the differences in causes of deaths across counties for the entire U.S.

Spin-1 Kitaev-Heisenberg model on a two-dimensional honeycomb lattice

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We study the Kitaev-Heisenberg model with spin-1 local degree of freedom on a two-dimensional honeycomb lattice numerically by density matrix renormalization group method. By tuning the relative value of the Kitaev and Heisenberg exchange couplings, we obtain the whole phase diagram with two spin liquid phases and four symmetry broken phases. We identify that the spin liquid phases are gapless by calculating the central charge at the pure Kitaev points without Heisenberg interaction. Comparing to its spin-1/2 counterpart, the position and number of gapless modes of the spin-1 case are quite different. Due to the approximate $Z_2$ local conservations, the expectation value of Wilson loop operator measuring the flux of each plaquette stays near to 1, and the static spin-spin correlations remain short-range in the entire spin liquid phases.

Design and Development of an Emoji Sentiment Lexicon

Publisher: name: Universität Regensburg

Subjects: subject: sentiment analysis; emojis; computer-mediated communication; natural language processing
subject: 020 Bibliotheks- und Informationswissenschaft

description: Emojis represent an essential means of expressing sentiments such as opinions and attitudes in computer-mediated communication, especially in chats and social media. To effectively capture these sentiments, the sentiments associated with the emojis used must be known. Previous approaches to determining the sentiments expressed with emojis require a large amount of manual annotation. For many emojis, especially less frequently used platform-specific emojis, studies on expressed sentiments do not yet exist. Therefore, these emojis cannot be considered in sentiment analyses so far. In this work, a method for effective and efficient determination of emojis’ sentiments and their compilation in a sentiment lexicon was developed. The determined sentiments are compiled as a sentiment lexicon. For this purpose, software was created in Python to process collections of texts into a corpus. The software derives the emojis’ sentiments as valence values based on the sentiments of the texts in which the emojis appear. The lexicons produced by the method can be used in lexicon-based sentiment analysis approaches. The method also derives other information on the emojis and their usage that can be used to assess the sentiment lexicon produced and the usage of the emojis. Using the developed method, two analyses were conducted with corpora of different text sources. The results and subsequent comparisons with existing sentiment lexicons have shown that the developed method is able to efficiently produce similar results as sentiment lexicons produced with manual annotation.

description: As conversational search becomes more pervasive, it becomes increasingly important to understand the user's underlying needs when they converse with such systems in diverse contexts. We report on an in-situ experiment to collect conversationally described information needs in a home cooking scenario. A human experimenter acted as the perfect conversational search system. Based on the transcription of the utterances, we present a coding scheme comprising 27 categories to annotate the information needs of users. Moreover, we use these annotations to perform prediction experiments based on random forest classification to establish the feasibility of predicting the information need from the raw utterances. We find that a reasonable accuracy in predicting information need categories is possible.

description: A chain of one-dimensional Schrödinger operators connected by successive Darboux transformations is called the ``Darboux chain'' or ``dressing chain''. The periodic dressing chain with period $N$ has a control parameter $α$. If $α\not= 0$, the $N$-periodic dressing chain may be thought of as a generalization of the fourth or fifth (depending on the parity of $N$) Painlevé equations . The $N$-periodic dressing chain has two different Lax representations due to Adler and to Noumi and Yamada. Adler's $2 \times 2$ Lax pair can be used to construct a transition matrix around the periodic lattice. One can thereby define an associated ``spectral curve'' and a set of Darboux coordinates called ``spectral Darboux coordinates''. The equations of motion of the dressing chain can be converted to a Hamiltonian system in these Darboux coordinates. The symplectic structure of this Hamiltonian formalism turns out to be consistent with a Poisson structure previously studied by Veselov, Shabat, Noumi and Yamada.

description: Agricultural systems are complex, because managers need to cope with interlinked and dynamic ecological, social, political and economic aspects. Understanding and analysing such systems requires researchers to adopt a holistic approach to grasp the links between those aspects. Holistic approaches within agricultural research – known as Farming Systems Research (FSR) support researchers in sharing knowledge and different perspectives concerning the research process and problems. Sharing knowledge and perspectives enables to holistically understand and conceptualise complex systems, as well as to structure and manage research projects. The aim of this paper is to suggest and present a guideline for agricultural researchers to carry out an economic and environmental analysis of food supply chains with a FSR approach. We describe how participants of the EU-project SOLIBAM (Strategies for Organic and Low-input Integrated Breeding and Management) used the guideline to structure, manage and carry out an economic and environmental analysis of the food supply chains of concern. The FSR approach enabled the participants to jointly define and model the structure of the supply chains, identify the requirements for data collection and collect data.

description: New carbothioamides, linked to chromene or benzo[f]chromene units, were taken as key synthons for the present study. These carbothioamides were prepared, in good yields, by the cyclocondensation of the appropriate 2-hydroxybenzaldehydes or 2-hydroxy-1-naphthaldehyde with 2-cyanoethanethioamide. Next, the precursors carbothioamides were reacted with different α-halocarbonyl compounds and bis(α-bromoketones). These reactions afforded the corresponding 4-(substituted)thiazoles and thiazol-4(5H)-ones, in addition to bis(thiazoles), linked to different cores. Additionally, thiazol-4(5H)-ones were condensed with the appropriate bis(aldehydes) to yield the corresponding bis(thiazol-4(5H)-ones), linked to chromene or benzo[f]chromene units via different cores.

description: We define a unital algebra $A$ over a field $\mathbb{F}$ to be nearly simple if $A$ contains a unique non-trivial ideal $I_A$ such that $I_A^2 \neq \{0\}$. If $A$ and $B$ are two nearly simple algebras, we consider the ideal structure of their tensor product $A \otimes B$. The obvious non-trivial ideals of $A \otimes B$ are: $$I_A \otimes I_B, \quad I_A \otimes B, \quad A \otimes I_B, \quad \mbox{and} \quad I_A \otimes B + A \otimes I_B.$$ The purpose of this paper is to characterize when are all non-trivial ideals of $A \otimes B$ of the above form.

description: Die Masterarbeit befasst sich mit kulturellen Unterschieden zwischen deutschen und lateinamerikanischen Teilnehmenden hinsichtlich der reflektiven und der intuitiven Ästhetikwahrnehmung von Homepages. Ziel war es, neben kulturellen Unterschieden auch allgemeine Divergenzen zwischen den Wahrnehmungsarten intuitiv und reflektiv bezüglich der Ästhetik von Homepages zu untersuchen. Die Ergebnisse der Arbeit bestätigen dabei die Wichtigkeit einer kulturellen Adaption von Websites, da vor allem in der intuitiven Wahrnehmung kulturelle Unterschiede aufgezeigt werden konnten. Sie zeigen außerdem, dass Websites insbesondere in Aspekten der Kunstfertigkeit optimiert werden sollten, da diese kulturunabhängig am stärksten mit der Ästhetikbewertung korrelierten. Die Arbeit wurde am Institut für Informationswissenschaft und Sprachtechnologie der Universität Hildesheim im Masterstudiengang Internationales Informationsmanagement – Informationswissenschaft verfasst.

description: The in-plane thermal conductivity $k$ of the two-dimensional antiferromagnetic monolayer cuprate Sr$_2$CuO$_2$Cl$_2$ is studied. Analysis of the unusual temperature dependence of $k$ reveals that at low temperatures the heat is carried by phonons, whereas at high temperatures magnetic excitations contribute significantly. Comparison with other insulating layered cuprates suggests that a large magnetic contribution to the thermal conductivity is an intrinsic property of these materials.

description: A vast and interesting family of natural semantics for belief revision is defined. Suppose one is given a distance d between any two models. One may then define the revision of a theory K by a formula a as the theory defined by the set of all those models of a that are closest, by d, to the set of models of K. This family is characterized by a set of rationality postulates that extends the AGM postulates. The new postulates describe properties of iterated revisions.

description: By using a farm’s data in Yantai City and the theory of Cost-Volume-Profit analysis and the financial management methods, this paper construct a multi-factor analysis model for improving profit management using Excel 2007 in Shellfish farming projects and describes the procedures to construct a multi-factor analysis model. The model can quickly calculate the profit, improve the level of profit management, find out the breakeven point and enhance the decision-making efficiency of businesses etc. It is also a thought of the application to offer suggestions for government decisions and economic decisions for corporations as a simple analysis tool. While effort has been exerted to construct a four-variable model, some equally important variables may not be discussed sufficiently due to limitation of the paper’s space and the authors’ knowledge. All variables can be listed in EXCEL 2007 and can be associated in a logical way to manage the profit of shellfish farming projects more efficiently and more practically.

description: We analyze the horizon and geodesic structure of a class of 4D off--diagonal metrics with deformed spherical symmetries, which are exact solutions of the vacuum Einstein equations with anholonomic variables. The maximal analytic extension of the ellipsoid type metrics are constructed and the Penrose diagrams are analyzed with respect to adapted frames. We prove that for small deformations (small eccentricities) there are such metrics that the geodesic behaviour is similar to the Schwarzcshild one. We conclude that some vacuum static and stationary ellipsoid configurations may describe black ellipsoid objects.

description: In this paper we describe the U-band imaging of the F02 deep field, one of the fields in the VIRMOS Deep Imaging Survey. The observations were done at the ESO/MPG 2.2m telescope at La Silla (Chile) using the 8k x 8k Wide-Field Imager (WFI). The field is centered at alpha(J2000)=02h 26m 00s and delta(J2000)=-04deg 30' 00", the total covered area is 0.9 deg**2 and the limiting magnitude (50% completeness) is U(AB) ~ 25.4 mag. Reduction steps, including astrometry, photometry and catalogue extraction, are first discussed. The achieved astrometric accuracy (RMS) is ~ 0.2" with reference to the I-band catalog and ~ 0.07" internally (estimated from overlapping sources in different exposures). The photometric accuracy including uncertainties from photometric calibration, is < 0.1 mag. Various tests are then performed as a quality assessment of the data. They include: (i) the color distribution of stars and galaxies in the field, done together with the BVRI data available from the VIMOS survey; (ii) the comparison with previous published results of U-band magnitude-number counts of galaxies.

description: A facile protocol for the synthesis of phenoxazines and benzopyridoxazines by Smiles rearrangement have been demonstrated in short reaction time under microwave irradiation. The control experiments suggest that a reaction proceeds through Smiles rearrangement followed SNAr ring closure by in situ cascade process. In our present work, both the electron donating and electron withdrawing groups were tolerant and provided a corresponding phenoxazine/benzopyridoxazine in good to moderate yields.

description: Forestry industry plays a key role in regulating climate and promoting sustainable development of society. Environmental responsibility is the key part of social responsibilities of forestry enterprises. Based on the particularity of forestry industry, the framework of social responsibility reports of forestry enterprises is provided, and major topics of social responsibilities followed by forestry enterprises are analyzed. Meanwhile, the core values of social responsibilities of forestry enterprises are pointed out. It is proposed that the social responsibility reports of forestry enterprises should involve the responsibility to shareholders and creditors, the responsibility to suppliers, customers and consumers, the responsibility to employees, the responsibility to the environment, and the responsibility to communities and charity behavior.

description: The fifth generation (5G) of wireless communication is in its infancy, and its evolving versions will be launched over the coming years. However, according to exposing the inherent constraints of 5G and the emerging applications and services with stringent requirements e.g. latency, energy/bit, traffic capacity, peak data rate, and reliability, telecom researchers are turning their attention to conceptualize the next generation of wireless communications, i.e. 6G. In this paper, we investigate 6G challenges, requirements, and trends. Furthermore, we discuss how artificial intelligence (AI) techniques can contribute to 6G. Based on the requirements and solutions, we identify some new fascinating services and use-cases of 6G, which can not be supported by 5G appropriately. Moreover, we explain some research directions that lead to the successful conceptualization and implementation of 6G.
