description: We review a recent construction of the free field equations for totally symmetric tensors and tensor-spinors that exhibits the corresponding linearized geometry. These equations are not local for all spins >2, involve unconstrained fields and gauge parameters, rest on the curvatures introduced long ago by de Wit and Freedman, and reduce to the local (Fang-)Fronsdal form upon partial gauge fixing. We also describe how the higher-spin geometry is realized in free String Field Theory, and how the gauge fixing to the light cone can be effected. Finally, we review the essential features of local compensator forms for the higher-spin bosonic and fermionic equations with the same unconstrained gauge symmetry.

description: Marketing methods play a vital role in the efficiency of any supply-chain relationship. The relationship between buyers and sellers in the agricultural sector is dynamic and complex. While livestock and grain markets in the U.S. are generally well studied, the price setting process, buyer-seller relationships, and factors which influence the type, duration, and timing of business relationships in the market for specialty crops (SC) are less well understood. This is particularly true in the case of buyer relationships with small-scale farms. A better understanding of the dynamic relationship between small-scale SC producers and buyers is essential in achieving efficient marketing outcomes. This issue is examined from the perspective of small-scale SC growers in Virginia (VA) and North Carolina (NC). Using a Choice Experiment (CE) approach, this study: (1) identifies key contract characteristics and buyer attributes which are valued by VA and NC small-scale SC producers; (2) quantifies tradeoffs VA and NC small-scale SC producers are willing to make between buyer attributes and contract characteristics when establishing a new contractual relationship; and (3) determines the factors influencing these tradeoffs. Mean willingness-to-pay (WTP) of contract attributes and individual-specific WTP estimates are recovered using a mixed-logit model. Using these individual-specific estimates, a random-effects model is then used to determine factors driving producer WTP. While expressing concerns about specific aspects of contracts, growers overall were found receptive to the idea of using contracts as a viable marketing channel alternative. Substantial heterogeneity is found to exist amongst growers in their attitudes towards the structural framework of produce contracts, suggesting that growers have competing marketing interests with varying preferences towards contract structure. All four non-price contract attributes are found to have significant WTP estimates at a 95% confidence interval or higher. A combination of producer demographics, farm operation characteristics, contract perceptions, and attribute processing strategies are shown to impact the overall WTP for the selected contract attributes. Additionally, growers’ preferences are found to be stable throughout the study.

description: By means of theory group analysis, some algebraic and geometrical properties of quaternion analogs of \emph{Julia} sets are investigated. We argue that symmetries, intrinsic to quaternions, give rise to the class of identical \emph{Julia} sets, which does not exist in complex number case. In the case of quadratic quaternionic mapping $X_{k+1} = X_k^2 + C$ these symmetries mean, that the shape of fractal \emph{Julia} set is completely defined by just two numbers, $C_0$ and $|{\bf C}|$. Moreover, for given $C_0$ the vector part of the \emph{Julia} set may be obtained by rotation of a two-dimensional \emph{Julia} subset of arbitrary plane, comprising ${\bf C}$, around the axis ${\bf n} = {\bf C}/|{\bf C}|$.

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.

description: The spread and burned areas of wildfires in Alberta, Canada during a 50 year period, from 1961 through 2010 are studied here. Meteorological factors that control the spread and burn area have been discussed for a long time. In this paper, we analyze the temperature rise that could drastically enhance the spread and average burned area of wildfires. A simple lattice model that mimics meteorological factors is also introduced to simulate the temperature effect on the spread and burned areas of wildfires. The numerical results demonstrate the temperature effects on wildfires when compared to the empirical data.

description: We present the last pointed observation of AM Her carried out during the life of the BeppoSAX satellite. It was bright at the beginning of the observation, but dropped to the lowest X-ray level ever observed so far. The X-ray emission during the bright period is consistent with accretion occurring onto the main pole of the magnetized white dwarf. The rapid change from the active state to the low deep state indicates a drop by a factor of 17 in the accretion rate and hence that accretion switched-off. The short timescale (less than one hour) of this variation still remains a puzzle. Optical photometry acquired simultaneousy during the low state shows that the white dwarf remains heated, although a weak emission from the accretion stream could be still present. Cyclotron radiation, usually dominating the V and R bands, is negligible thus corroborating the possibility that AM Her was in an off-accretion state. The X-ray emission during the inactive state is consistent with coronal emission from the secondary late type star.

description: Paper presents a new solver for numerical solution of the Boltzmann kinetic equation with Shakhov model collision integral (S-model) for arbitrary spatial domains. Numerical method utilizes Tensor-Train decomposition, which allows to reduce required computer memory for up to 30 times even on a moderate velocity mesh. This improvement is achieved by representing values of distribution function on the structured velocity mesh as a 3D tensor in Tensor-Train format. The resulting numerical method makes it possible to solve complex 3D problems on modern desktop computers. Our implementation may serve as a prototype code for researchers concerned with numerical solution of the kinetic equations in 3D domains by the discrete velocity method.

description: Transmittance of the colossal magnetoresistive compound Nd_0.5Sr_0.5MnO_3 showing metal-insulator phase transition has been studied by means of the submm- and mm-wavelength band spectroscopy. An unusually high transparency of the material provided direct evidence for the significant suppression of the coherent Drude weight in the ferromagnetic metallic state. Melting of the A-type antiferromagnetic states has been found to be responsible for a considerable increase in the microwave transmission, which was observed at the transition from the insulating to the metallic phase induced by magnetic field or temperature. This investigation confirmed a dominant role of the (x^2-y^2)-orbital degree of freedom in the low-energy optical properties of Nd_0.5Sr_0.5MnO_3 and other doped manganites with planar (x^2-y^2)-orbital order, as predicted theoretically. The results are discussed in terms of the orbital-liquid concept.

description: The present study was carried out to identify and characterize the pathogen responsible for cashew seedling wilt, and to find its control measures. Characteristic symptoms of wilt included yellowing and drying of the lower leaves at the initial stage. In the advanced stage, drooping and wilting of the top portion of the seedling was more common. Pathogen Fusarium falciforme, was identified based on the morphological characteristics and ITS sequence data. Several fungicidal formulations effectively reduced the intensity and severity of seedling wilt disease. Phylogenetic analysis placed all the five isolates into a single cluster. A mixture of Trifloxystrobin and Tebuconazole inhibited the pathogen in terms of mycelial growth, followed by Carbendazim + Mancozeb with ED50 values of 4.370 and 8.427 ppm, respectively. However, mixture of Carbendazim and Mancozeb was found the best suitable fungicide formulation to reduce the severity of wilt disease and the highest percent disease control over the untreated one.

description: High-frequency quasi-periodic oscillations (HFQPOs) observed in the emission of black-hole X-ray binary systems promise insight into strongly curved spacetime. `Discoseismic' oscillations with frequencies set by the intrinsic properties of the central black hole, in particular `trapped inertial waves' (r-modes), offer an attractive explanation for HFQPOs. To produce an observable signature, however, such oscillations must be excited to sufficiently large amplitudes. Turbulence driven by the magnetorotational instability (MRI) fails to provide the necessary amplification, but r-modes may still be excited via interaction with accretion disc warps or eccentricities. We present 3D global hydrodynamic simulations of relativistic accretion discs, which demonstrate for the first time the excitation of trapped inertial waves by an imposed eccentricity in the flow. While the r-modes' saturated state depends on the vertical boundary conditions used in our unstratified, cylindrical framework, their excitation is unambiguous in all runs with eccentricity >0.005 near the ISCO. These simulations provide a proof of concept, demonstrating the robustness of trapped inertial wave excitation in a non-magnetized context. In a companion paper, we explore the competition between this excitation, and damping by magnetohydrodynamic turbulence.

The membrane at the end of the (de Sitter) universe

description: The original {\it membrane at the end of the universe} corresponds to a probe $M2$-brane of signature $(2,1)$ occupying the $S^{2} \times S^{1}$ boundary of the $(10,1)$ spacetime $AdS_{4} \times S^{7}$, and is described by an $OSp(4/8)$ SCFT. However, it was subsequently generalized to other worldvolume signatures $(s,t)$ and other spacetime signatures $(S,T)$. An interesting special case is provided by the $(3,0)$ brane at the end of the de Sitter universe $dS_{4}$ which has recently featured in the $dS/CFT$ correspondence. The resulting CFT contains the one recently proposed as the holographic dual of a four-dimensional de Sitter cosmology. Supersymmetry restricts $S,T,s,t$ by requiring that the corresponding bosonic symmetry $O(s+1,t+1) \times O(S-s,T-t)$ be a subgroup of a superconformal group. The case of $dS_{4} \times AdS_{7}$ is `doubly holographic' and may be regarded as the near horizon geometry of $N_{2}$ $M2$-branes or equivalently, under interchange of conformal and R symmetry, of $N_{5}$ $M5$-branes, provided $N_{2}=2N_{5}{}^{2}$. The same correspondence holds in the pp-wave limit of conventional $M$-theory.

description: We study the time evolution of a complex scalar field in the symmetry broken phase in the presence of oscillating spacetime metric background. In our (2+1)-dimensional simulations, we show that the spacetime oscillations can excite an initial field configuration, which ultimately leads to the formation of topological vortices in the system. At late times, field configuration achieves a disordered state. A detailed study of the momentum and frequency modes of the field reveals that these field excitations are driven by the phenomenon of parametric resonance. In extremely high frequency regime where frequency of spacetime oscillations is much larger than the field-mass, the formed vortices are not topological in nature. Interestingly in this regime, for a suitable choice of parameters of the simulation, we observe a persistent lattice structure of vortex-antivortex pairs. We discuss applications of our study to the dynamics of interior superfluidity of neutron stars during binary neutron star mergers, in generation of excitation in ultralight axion-like field near a strong gravitational wave source, etc.

description: Food away from home (FAFH) is known to be of poorer nutritional quality. Given the increased prominence of FAFH over the past 35 years, some policymakers and health advocates seek to further regulate this market. This policy approach is only as strong as its expected impact. Using an individual fixed effects approach, we first document how FAFH (both fast food and restaurants) has had a relatively stable negative impact on dietary quality over 1977-2010. Yet, overall levels of dietary quality have increased over 20% during this period. To this end, we use an Oaxaca-Blinder decomposition approach to understand how changes in FAFH choices and observable characteristics of individuals have impacted the trajectory of dietary improvements. We find that increased consumption of FAFH plays a very small role in explaining changes in dietary quality (about 4%) as compared to changes in demographics (e.g., age and race/ethnicity -- about 5%) and human capital (e.g., education -- about 7.5%). We attribute the substantial residual, or unexplained, improvement to changes in unobservable factors (e.g., consumer preferences, the food environment, and overlapping nutrition policy initiatives).

description: In this paper, we propose a novel learning-based pipeline for partially overlapping 3D point cloud registration. The proposed model includes an iterative distance-aware similarity matrix convolution module to incorporate information from both the feature and Euclidean space into the pairwise point matching process. These convolution layers learn to match points based on joint information of the entire geometric features and Euclidean offset for each point pair, overcoming the disadvantage of matching by simply taking the inner product of feature vectors. Furthermore, a two-stage learnable point elimination technique is presented to improve computational efficiency and reduce false positive correspondence pairs. A novel mutual-supervision loss is proposed to train the model without extra annotations of keypoints. The pipeline can be easily integrated with both traditional (e.g. FPFH) and learning-based features. Experiments on partially overlapping and noisy point cloud registration show that our method outperforms the current state-of-the-art, while being more computationally efficient.

description: This paper analyzes the multivariate stochastic volatilities with a common factor which is affecting both the volatilities of crude oil and agricultural commodity prices in both biofuel and non-biofuel use. We develop a stochastic volatility model which has a latent common volatility with two asymptotic regimes and a smooth transition between them. In contrast with conventional volatility models, stochastic volatilities in this study are generated by a logistic transformation of the latent factors, which consists of two components: the common volatility factor and the idiosyncratic component. In this study, we analyze the stochastic volatility model with a common factor for oil, corn and wheat from August 8, 2005 to October 10, 2014 using a Markov-Chain-Monte-Carlo (MCMC) method and estimate the stochastic volatilities and also extract the common factor. Our results suggest that the volatility of oil and grain markets are very persistent since the common factor generating the stochastic volatilities of oil and commodity markets is highly persistent. In addition, the volatilities of oil prices are more affected by a common factor while the volatilities of corn are more determined by the idiosyncratic component.

description: Binary symmetry constraints of the N-wave interaction equations in 1+1 and 2+1 dimensions are proposed to reduce the N-wave interaction equations into finite-dimensional Liouville integrable systems. A new involutive and functionally independent system of polynomial functions is generated from an arbitrary order square matrix Lax operator and used to show the Liouville integrability of the constrained flows of the N-wave interaction equations. The constraints on the potentials resulting from the symmetry constraints give rise to involutive solutions to the N-wave interaction equations, and thus the integrability by quadratures are shown for the N-wave interaction equations by the constrained flows.

description: The study of shapes of the images of objects is an important issue not only because it reveals its dynamical state but also it helps to understand the object's evolutionary history. We discuss a new technique in cosmological image analysis which is based on a set of non-parametric shape descriptors known as the Minkowski Functionals (MFs). These functionals are extremely versatile and under some conditions give a complete description of the geometrical properties of objects. We believe that MFs could be a useful tool to extract information about the shapes of galaxies, clusters of galaxies and superclusters. The information revealed by MFs can be utilized along with the knowledge obtained from currently popular methods and thus could improve our understanding of the true shapes of cosmological objects.

description: One of the features of the production system in many countries of West Africa is the coexistence of both collectively-managed and individually-managed ‘private’ plots within the same. Within these households, economic activities are influenced by socio-cultural norms, which impact agricultural input decisions. This paper uses a two-year panel data on Mali to investigate intrahousehold allocation of productive resources across collective plots and ‘private’ plots. A major contribution of this paper is the clear distinction it makes between collective plots and the head’s ‘private’ plots, which is vital in understanding whether the observed yield and input differentials across collective plots and ‘private’ plots are due to headship or to the attributes of the collective plots. We find that significantly higher yields are achieved on collective plots relative to ‘private’ plots and this yield differential persists after restricting the sample to heads that control the collective plots and their own private plots. The estimations of the intensity of labor use show that collective plots are more intensively farmed with male-labor and child labor whereas the opposite is observed for femalelabor. However, after isolating the gender effect by excluding female-controlled plots from the sample, we find that collective plots are more intensively farmed than male-controlled ‘private’ plots regardless of the labor source. We infer from these results the importance of taking the gender component into account when studying intrahousehold farm-labor allocation. Unlike previous similar studies that only focus on labor allocation, we also investigate chemical fertilizer application. We find that the probability of fertilizer application tends to be higher on ‘private’ plots while the intensity of its use is higher for collective plots. These contrasting findings highlight the importance to investigate not only the probability of the use of a given technology but also the intensity of its application, especially for inputs such as fertilizer that requires a certain amount in order to obtain a yield response.

description: We model a regional grain reserve as a game of two countries that agree to pool together a fraction of their grain to cope with production risk, but that can also repudiate their obligations at any moment. The reserve can be operated as a “credit union” or an “insurance union”. We find that although risk sharing is more effective when production shocks are negatively correlated, the regional reserve is more sustainable when the correlation is positive. We also find that an “insurance” game can be more sustainable than a “credit” game.

description: The lack of well-structured annotations in a growing amount of RNA expression data complicates data interoperability and reusability. Commonly - used text mining methods extract annotations from existing unstructured data descriptions and often provide inaccurate output that requires manual curation. Automatic data-based augmentation (generation of annotations on the base of expression data) can considerably improve the annotation quality and has not been well-studied. We formulate an automatic augmentation of small RNA-seq expression data as a classification problem and investigate deep learning (DL) and random forest (RF) approaches to solve it. We generate tissue and sex annotations from small RNA-seq expression data for tissues and cell lines of homo sapiens. We validate our approach on 4243 annotated small RNA-seq samples from the Small RNA Expression Atlas (SEA) database. The average prediction accuracy for tissue groups is 98% (DL), for tissues - 96.5% (DL), and for sex - 77% (DL). The "one dataset out" average accuracy for tissue group prediction is 83% (DL) and 59% (RF). On average, DL provides better results as compared to RF, and considerably improves classification performance for 'unseen' datasets.

Externalizing behaviors

description: Attachment theory is a core theory of child development. The theory proposes a framework to understand how children’s early relationships to their caregiver shape children’s lifelong development. Most attachment research, however, is limited to categorical assessments of infant-mother attachment. This results in a reductionist understanding of children’s development, one that rests on a number of questionable assumptions. From an assessment perspective, categorical measures of attachment assume that all children fit neatly into a fixed number of categories, and that all children within a category present similar attachment behaviors. From a developmental perspective, a focus on infant attachment assumes little change in children’s caregiving environments, and this, despite evidence showing that changes may occur between infancy and the preschool years. Such changes influence child-caregiver attachment relationships. From a caregiver perspective, children’s relationships with their mothers are influential, but they do not span the gamut of children’s early relationships. Fathers, for example, are increasingly involved in child rearing and are influential in children’s development. This dissertation sought to overcome these limitations through the use of the Preschool Attachment Rating Scales (PARS), a novel, continuous measure of child-caregiver preschool attachment. The first study demonstrated the reliability and validity of the PARS as a measure of child-mother and child-father preschool attachment. This study examined the inter-rater reliability, the convergent validity, the construct validity, the predictive validity, and the incremental validity of the PARS. The second study used a longitudinal design to examine the independent and interactive influence of child-mother and child-father attachment in the preschool years on boys’ and girls’ externalizing behaviors in middle childhood. This latter study showed that the prediction of externalizing behavior varied as a function of children’s and parents’ genders, as well as the attachment pattern (e.g., security, avoidance). Taken together, this dissertation shows that a continuous measure of attachment can help uncover the complexity of different attachment patterns, and in turn, provide a more nuanced understanding on how such patterns affect children’s social, emotional, and psychopathological development.
Yang-Mills theory in terms of gauge invariant dual variables

description: Quantum Yang-Mills theory and the Wilson loop can be rewritten identically in terms of local gauge-invariant variables being directly related to the metric of the dual space. In this formulation, one reveals a hidden high local symmetry of the Yang-Mills theory, which mixes up fields with spins up to J=N for the SU(N) gauge group. In the simplest case of the SU(2) group the dual space seems to tend to the de Sitter space in the infrared region. This observation suggests a new mechanism of gauge-invariant mass generation in the Yang-Mills theory.

A Reduced Study for Nematic Equilibria on Two-Dimensional Polygons

description: We study reduced nematic equilibria on regular two-dimensional polygons with Dirichlet tangent boundary conditions, in a reduced two-dimensional Landau-de Gennes framework, discussing their relevance in the full three-dimensional framework too. We work at a fixed temperature and study the reduced stable equilibria in terms of the edge length, $λ$ of the regular polygon, $E_K$ with $K$ edges. We analytically compute a novel "ring solution" in the $λ\to 0$ limit, with a unique point defect at the centre of the polygon for $K \neq 4$. The ring solution is unique. For sufficiently large $λ$, we deduce the existence of at least $\left[K/2 \right]$ classes of stable equilibria and numerically compute bifurcation diagrams for reduced equilibria on a pentagon and hexagon, as a function of $λ^2$, thus illustrating the effects of geometry on the structure, locations and dimensionality of defects in this framework.

The Nuclear Regions of the Seyfert Galaxy NGC 4151 - Parsec-scale HI Absorption and a Remarkable Radio Jet

description: Sensitive high angular and linear resolution radio images of the 240-pc radio jet in NGC4151, imaged at linear resolutions of 0.3 to 2.6 pc using the VLBA and phased VLA at 21 cm, are presented and reveal for the first time a faint, highly collimated jet (diameter <1.4 pc) underlying discrete components, seen in lower resolution MERLIN and VLA images, that appear to be shock-like features associated with changes in direction as the jet interacts with small gas clouds within the central 100 pc of the galaxy. In addition, 21-cm spectral line imaging of the neutral hydrogen in the nuclear region reveals the spatial location, distribution and kinematics of the neutral gas detected previously in a lower resolution MERLIN study. Neutral hydrogen absorption is detected against component C4W (E+F) as predicted by Mundell et al, but the absorption, extending over 3 pc, is spatially and kinematically complex on sub-parsec scales, suggesting the presence of small, dense gas clouds with a wide range of velocities and column densities. The main absorption component matches that detected in the MERLIN study and is consistent with absorption through a clumpy neutral gas layer in the putative obscuring torus, with higher velocity blue- and red-shifted systems with narrow linewidths also detected across E+F. The spatial location and distribution of the absorbing gas across component E+F rules out component E as the location of the AGN (as suggested by Ulvestad et al.) and, in combination with the well-collimated continuum structures seen in component D, suggests that component D is the most likely location for the AGN. We suggest that components C and E are shocks produced in the jet as the plasma encounters, and is deviated by, dense clouds with diameters smaller than ~1.4 pc. (Abridged)

description: An important aspect of health monitoring is effective logging of food consumption. This can help management of diet-related diseases like obesity, diabetes, and even cardiovascular diseases. Moreover, food logging can help fitness enthusiasts, and people who wanting to achieve a target weight. However, food-logging is cumbersome, and requires not only taking additional effort to note down the food item consumed regularly, but also sufficient knowledge of the food item consumed (which is difficult due to the availability of a wide variety of cuisines). With increasing reliance on smart devices, we exploit the convenience offered through the use of smart phones and propose a smart-food logging system: FoodAI, which offers state-of-the-art deep-learning based image recognition capabilities. FoodAI has been developed in Singapore and is particularly focused on food items commonly consumed in Singapore. FoodAI models were trained on a corpus of 400,000 food images from 756 different classes. In this paper we present extensive analysis and insights into the development of this system. FoodAI has been deployed as an API service and is one of the components powering Healthy 365, a mobile app developed by Singapore's Heath Promotion Board. We have over 100 registered organizations (universities, companies, start-ups) subscribing to this service and actively receive several API requests a day. FoodAI has made food logging convenient, aiding smart consumption and a healthy lifestyle.

description: The status of exponential scalar potentials in supergravity is reviewed, and updated. One version of N=8 D=4 supergravity with a positive exponential potential, obtainable from a `non-compactification' of M-theory, is shown to have an accelerating cosmological solution that realizes `eternal quintessence'. Some implications for a de Sitter version of the domain wall/QFT correspondence are discussed.
description: 15 pp. Revised to correct the analysis in the previous (and published) version of a particular class of massive supergravity theories (of secondary interest to the theme of the paper). Minor numerical errors and typos have been corrected too
