description: We derive joint constraints on the warm dark matter (WDM) half-mode scale by combining the analyses of a selection of astrophysical probes: strong gravitational lensing with extended sources, the Lyman-$α$ forest, and the number of luminous satellites in the Milky Way. We derive an upper limit of $λ_{\rm hm}=0.089{\rm~Mpc~h^{-1} }$ at the 95 per cent confidence level, which we show to be stable for a broad range of prior choices. Assuming a Planck cosmology and that WDM particles are thermal relics, this corresponds to an upper limit on the half-mode mass of $M_{\rm hm }< 3 \times 10^{7} {\rm~M_{\odot}~h^{-1}}$, and a lower limit on the particle mass of $m_{\rm th }> 6.048 {\rm~keV}$, both at the 95 per cent confidence level. We find that models with $λ_{\rm hm}> 0.223 {\rm~Mpc~h^{-1} }$ (corresponding to $m_{\rm th }> 2.552 {\rm~keV}$ and $M_{\rm hm }< 4.8 \times 10^{8} {\rm~M_{\odot}~h^{-1}}$) are ruled out with respect to the maximum likelihood model by a factor $\leq 1/20$. For lepton asymmetries $L_6>10$, we rule out the $7.1 {\rm~keV}$ sterile neutrino dark matter model, which presents a possible explanation to the unidentified $3.55 {\rm~keV}$ line in the Milky Way and clusters of galaxies. The inferred 95 percentiles suggest that we further rule out the ETHOS-4 model of self-interacting DM. Our results highlight the importance of extending the current constraints to lower half-mode scales. We address important sources of systematic errors and provide prospects for how the constraints of these probes can be improved upon in the future.

Fig. 2 a.
Suctorian ciliate with very large (up to 5 mm) branched body. Several fascicles of tentacles placed at the numerous actinophores which are elevated over the substrate. Single macronucleus branched reaching the actinophores. Micronuclei are numerous. The shape of body is extremely variable depending on the type of substrate. Thus at the more or less flat substrate the individuals (especially young), have irregularly shaped flattened body with short, unramified actinophores, whereas on complex sufaces, i.e. aquatic invertebrates, the body might be dendritic with long branched actinophores. Reproduction by multiple endogenous budding.
Dimensions of individuals: body width 150–380; actinophore length 30–140; length of tentacles 10–30. Previous measurements: vertical length until 550; length of tentacles 75–90.

Gauged Wess-Zumino Model in Noncommutative Minkowski Superspace

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We develop a gauged Wess-Zumino model in noncommutative Minkowski superspace. This is the natural extension of the work of Carlson and Nazaryan, which extended N=1/2 supersymmetry written over deformed Euclidean superspace to Minkowski superspace. We investigate the interaction of the vector and chiral superfields. Noncommutativity is implemented by replacing products with star products. Although, in general, our star product is nonassociative, we prove that it is associative to the first order in the deformation parameter. We show that our model reproduces the N=1/2 theory in the appropriate limit. Essentially, we find the N=1/2 theory and a conjugate copy. As in the N=1/2 theory, a reparameterization of the gauge parameter, vector superfield and chiral superfield are necessary to write standard C-independent gauge theory. However, our choice of parameterization differs from that used in the N=1/2 supersymmetry, which leads to some unexpected new terms.

description: Stanene, the two-dimensional monolayer form of tin, has been predicted to be a 2D topological insulator due to its large spin--orbit interaction. However, a clear experimental demonstration of stanene's topologically nontrivial properties has eluded observation, in part because of the difficulty of choosing a substrate on which stanene will remain topologically nontrivial. In this paper, we present first-principles density functional theory (DFT) calculations of epitaxial monolayer stanene grown on the (0001) surface of alumina, Al$_{2}$O$_{3}$, as well as free-standing decorated stanene under strain. By describing the energetics and nature of how monolayer stanene binds to alumina, we show a strong energetic drive for the monolayer to be coherently strained and epitaxial to the substrate. By analyzing the electronic structure of strained stanene, we find it to be a quantum spin Hall insulator on Al$_{2}$O$_{3}$. We also describe the effect of \emph{in situ} fluorine decoration on the bound stanene monolayer, including on its potential for mechanical exfoliation.

Oldtimers, newcomers, and social class : group affiliation and social influence in Lethbridge, Alberta
Creators: name: Marlor, Chantelle Patricia
Publisher: name: University of British Columbia
Year: 2009

description: The results of an ethnohistorical study of Lethbridge, Alberta led to my questioning current presumptions in the Canadian social inequality literature that social class, income, educational attainment, gender and ethnicity are principal factors in shaping social inequality in Canada. The ethnographic evidence suggests that membership criteria associated with locally-defined, historically-evolved groups mark who has political influence (a specific form of social power), and where the ensuing social inequalities lie in Lethbridge. A theoretical framework describing how historical circumstances lead to the redefinition of which socially-defined characteristics become local status markers is presented as the underlying theoretical orientation of this thesis. The framework does not preclude the possibility that social groups other than those studied in this thesis use social class, occupation, income, education, gender and ethnicity as status characteristics or group membership criteria. The framework is my attempt to clarify the often-unclear relationship among social inequality concepts. A mail-out social survey (N=238) was used to empirically test the hypothesis that Lethbridge group membership is a better predictor than social class, income, educational attainment, gender and/or ethnicity of who has political influence in Lethbridge community decision-making. Data was analyzed using analysis of variance (ANOVA), bivariate correlation, and multiple regression. Mixed levels of support were found for the Lethbridge group hypotheses, with the "fits in" and "local trade/business people" receiving considerable support; North/South/West sider, and religious affiliation receiving some support; and Old-timers receiving no support. In contrast, the only social inequality hypothesis to receive more than minimal support was level of education. It is concluded that status characteristics are more fluid, local and historically negotiated than assumed in the social inequality literature. Suggested directions for future theoretical and empirical work include refinement of the relationships among social inequality variables and further empirical tests of the theoretical framework proposed here.

description: We investigate rotating effect on deconfinement phase transition in an Einstein-Maxwell-Dilaton(EMD) model in bottom-up holographic QCD approach. By constructing a rotating black hole, which is supposed to be dual to rotating strongly coupled nuclear matter, we investigate the thermodynamic quantities, including entropy density, pressure, energy density, trace anomaly, sound speed and specific heat for both pure gluon system and two-flavor system under rotation. It is shown that those thermodynamic quantities would be enhanced by large angular velocity. Also, we extract the information of phase transition from those thermodynamic quantities, as well as the order parameter of deconfinement phase transition, i.e. the loop operators. It is shown that, in the $T - ω$ plane, for two-flavor case with small chemical potential, the phase transition is always crossover. The transition temperature decreases slowly with angular velocity and chemical potential. For pure gluon system with zero chemical potential, the phase transition is always first order, while at finite chemical potential a critical end point(CEP) will present in the $T - ω$ plane.

Lensed CMB simulation and parameter estimation

description: Modelling of the weak lensing of the CMB will be crucial to obtain correct cosmological parameter constraints from forthcoming precision CMB anisotropy observations. The lensing affects the power spectrum as well as inducing non-Gaussianities. We discuss the simulation of full sky CMB maps in the weak lensing approximation and describe a fast numerical code. The series expansion in the deflection angle cannot be used to simulate accurate CMB maps, so a pixel remapping must be used. For parameter estimation accounting for the change in the power spectrum but assuming Gaussianity is sufficient to obtain accurate results up to Planck sensitivity using current tools. A fuller analysis may be required to obtain accurate error estimates and for more sensitive observations. We demonstrate a simple full sky simulation and subsequent parameter estimation at Planck-like sensitivity. The lensed CMB simulation and parameter estimation codes are publicly available.

description: We have developed the mean-field theory of coexisting charge-density waves (CDW) and unconventional charge-density waves (UCDW). The double phase transition manifests itself in the thermodynamic quantities and in the magnetic response, such as spin susceptibility and spin-lattice relaxation rate. Our theory applies to quasi-one dimensional (TaSe_4)_2I, where above the CDW transition, thermal fluctuations die out rapidly, but robust pseudogap behaviour is still detected. We argue, that the fluctuations are suppressed due to UCDW, which partially gaps the Fermi surface, and causes non-Fermi-liquid (pseudogap) behaviour.

description: This report outlines the development and production of tailored dissemination materials, which were developed as part of Deliverable 7.4 “Project leaflet and other materials” under Work Package 7 (WP7). Due to the complex nature of the project and the wide variety of actors and stakeholders it aims to reach and engage, tailored dissemination is crucial; e.g. a one-pager to communicate policy recommendations to high-level policy actors is very different from a webinar laying out the food systems challenges to a wider audience. Therefore, various dissemination materials were created, including among others a project leaflet (booklet), roll-up for physical meetings, press releases, website content, E-newsletters, social media messages, policy recommendation, audio-visual materials, a scientific article, an infographic, progress articles and a conference booklet. Besides the materials that have already been completed, this report also highlights the plans for dissemination materials that are yet to be released. This deliverable is linked to Task 7.4 “Development and production of tailored dissemination materials”.

description: Italy's relatively small area, high population density, and high land and labor costs have created the challenges of ensuring profitably for agricultural producers, slowing urban encroachment onto arable land, and keeping farm families on land that has been handed down within the families for generations. As part of the solution to these issues, the European Union is enacting policies to reduce producer dependence on direct subsidies while increasing the competitiveness of agricultural products and returns to producers, reinvigorating rural communities, and encouraging environmentally sound production methods. These regulations provide incentives for producers to add value to their products by obtaining legal recognition of typical products, participating in agritourism, and helping to promote traditional products for regional food systems. This paper examines how E.U. and national policies are encouraging farmers in the Veneto region of Italy to adopt an agricultural production model that encourages limited production of high-quality, high-value products and more diversified land use.

description: Here we report on the experimental investigation of thermally induced fluctuations of the relative phase between two Bose-Einstein condensates which are coupled via tunneling. The experimental control over the coupling strength and the temperature of the thermal background allows for the quantitative analysis of the phase fluctuations. Furthermore, we demonstrate the application of these measurements for thermometry in a regime where standard methods fail. With this we confirm that the heat capacity of an ideal Bose gas deviates from that of a classical gas as predicted by the third law of thermodynamics.

description: We describe quantum circuits with only $\widetilde{\cal O}(N)$ Toffoli complexity that block encode the spectra of quantum chemistry Hamiltonians in a basis of $N$ arbitrary (e.g., molecular) orbitals. With ${\cal O}(λ/ ε)$ repetitions of these circuits one can use phase estimation to sample in the molecular eigenbasis, where $λ$ is the 1-norm of Hamiltonian coefficients and $ε$ is the target precision. This is the lowest complexity that has been shown for quantum computations of chemistry within an arbitrary basis. Furthermore, up to logarithmic factors, this matches the scaling of the most efficient prior block encodings that can only work with orthogonal basis functions diagonalizing the Coloumb operator (e.g., the plane wave dual basis). Our key insight is to factorize the Hamiltonian using a method known as tensor hypercontraction (THC) and then to transform the Coulomb operator into an isospectral diagonal form with a non-orthogonal basis defined by the THC factors. We then use qubitization to simulate the non-orthogonal THC Hamiltonian, in a fashion that avoids most complications of the non-orthogonal basis. We also reanalyze and reduce the cost of several of the best prior algorithms for these simulations in order to facilitate a clear comparison to the present work. In addition to having lower asymptotic scaling spacetime volume, compilation of our algorithm for challenging finite-sized molecules such as FeMoCo reveals that our method requires the least fault-tolerant resources of any known approach. By laying out and optimizing the surface code resources required of our approach we show that FeMoCo can be simulated using about four million physical qubits and under four days of runtime, assuming $1\,μ$s cycle times and physical gate error rates no worse than $0.1\%$.

description: Australia and New Zealand are major beef producing countries and major beef exporters. Unlike the case in the United States, where less than 10 percent of beef is exported, approximately 60 percent of Australia's and 85 percent of New Zealand's beef production is exported. Because of their dependency on a diverse set of export customers, these two countries are developing quality assurance programs that differentiate their beef in the global market and assure individual customers that the product is safe and meets customer needs. The Australian government and beef industry have invested in innovative identification, grading, and quality assurance systems that can be used by processors, producers, and supply chains. New Zealand relies upon individual processors to develop and implement quality assurance programs with their producers and suppliers. Using these innovations, supply chains have been able to distance themselves from the commodity market.

description: The concordance of the $Λ$CDM cosmological model in light of current observations has been the subject of an intense debate in recent months. The 2018 Planck Cosmic Microwave Background (CMB) temperature anisotropy power spectrum measurements appear at face value to favour a spatially closed Universe with curvature parameter $Ω_K<0$. This preference disappears if Baryon Acoustic Oscillation (BAO) measurements are combined with Planck data to break the geometrical degeneracy, although the reliability of this combination has been questioned due to the strong tension present between the two datasets when assuming a curved Universe. Here, we approach this issue from yet another point of view, using measurements of the full-shape (FS) galaxy power spectrum, $P(k)$, from the Baryon Oscillation Spectroscopic Survey DR12 CMASS sample. By combining Planck data with FS measurements, we break the geometrical degeneracy and find $Ω_K=0.0023 \pm 0.0028$. This constrains the Universe to be spatially flat to sub-percent precision, in excellent agreement with results obtained using BAO measurements. However, as with BAO, the overall increase in the best-fit $χ^2$ suggests a similar level of tension between Planck and $P(k)$ under the assumption of a curved Universe. While the debate on spatial curvature and the concordance between cosmological datasets remains open, our results provide new perspectives on the issue, highlighting the crucial role of FS measurements in the era of precision cosmology.

description: We assess the international competitiveness of the dairy industries in Argentina and Chile, combining recent market intelligence gathered from field visits with quantitative simulations of global policy reform scenarios. Both countries exhibit strong potential for export growth but face significant internal and external barriers to expanding their dairy industries. Global policy reforms would resolve some of the international obstacles to their expansion. Argentina has great potential, but it is handicapped by its current macroeconomic policies, trade policy distortions, and the uncertainty associated with policy implementation. Chile is more limited in terms of natural capacity for expansion, but it has a positive trade and investment environment.

description: We present an analysis of exclusive charmless semileptonic B-meson decays based on 83 million BBbar pairs recorded with the BABAR detector at the Upsilon(4S) resonance. Using isospin symmetry, we measure branching fractions B(B0 --> pi- l+ nu) = (1.38 +- 0.10 +- 0.16 +- 0.08) x 10^-4 and B(B0 --> rho- l+ nu) = (2.14 +- 0.21 +- 0.48 +- 0.28) x 10^-4, where the errors are statistical, experimental systematic, and due to form-factor shape uncertainties. We compare the measured distribution in q^2, the momentum-transfer squared, with theoretical predictions for the form factors from lattice QCD and light-cone sum rules, and extract the Cabibbo-Kobayashi-Maskawa (CKM) matrix element |V_{ub}| = (3.82 +- 0.14 +- 0.22 +- 0.11 +0.88 -0.52) x 10^-3 from B --> pi l nu, where the fourth error reflects the uncertainty of the form-factor normalization.

description: Declining grain prices, cyclical livestock prices, changing consumer preferences, and intense international competition for agricultural commodity markets have created a need for alternative production and marketing strategies. Iowa producers striving to break away from commodity production and to develop more lucrative value-added and niche markets must figure out how to increase both the consumer appeal and economic value of their products. Even if mild, sweet spring onions were a major cash crop in Iowa, producers could not market them as Vidalia onions. A legislated geographical limitation on supply is part of the success of Vidalia onions as an internationally recognized, branded product that can command a price premium in supermarkets across the United States. Vidalia onions are an example of how responding to consumer demand with a succession of marketing, legislative, and research events has protected a niche market from becoming oversupplied by producers. And, by protecting the name, quality, and image of an agricultural product through state ownership of the trademark, higher values are realized throughout the marketing chain.

description: New Zealand has used country-of-origin labeling (COOL) as a "country brand" to differentiate New Zealand lamb in international markets and increase consumer awareness of this lamb as a high-quality imported product. The case of New Zealand lamb is especially interesting as an unsubsidized commodity product competing against subsidized lamb in some of the most competitive and sophisticated retail markets in the world. Given New Zealand's dependence on international markets, producers, processors, and exporters needed to develop strategies to create and maintain a strong positive image for their product. This paper explores the history of New Zealand lamb exports, the focus on quality and meeting consumer specifications, and differences in the use and effectiveness of New Zealand as a country brand for lamb in different import markets. The paper also notes how COOL regulations might create country brands that increase demand for imported meats.

description: This paper provides the asymptotic analysis of the loss probability in the $GI/M/1/n$ queueing system as $n$ increases to infinity. The approach of this paper is alternative to that of the recent papers of Choi and Kim [2000] and Choi et al [2000] and based on application of modern Tauberian theorems with remainder. This enables us to simplify the proofs of the results on asymptotic behavior of the loss probability of the abovementioned paper of Choi and Kim [2000] as well as to obtain some new results.

description: We will introduce a new method to derive the orbital elements of the spectroscopic binary stars. Fitting the adopted radial velocity curves on the measured experimental data, the corresponding radial acceleration data are obtained. The orbital parameters are estimated by the nonlinear least squares of the radial velocity-acceleration curves. This method is implemented for the three double line spectroscopic binary systems RZ CAS, CC Cas and V1130 Tau. Numerical calculations show that the result are in good agreement with the those obtained by others using the method of Lehmann-Filhés.

Built: (re)constructing masculinity and authority in 1 Corinthians 7
Creators: name: Wilkinson, Kevin Wayne
Publisher: name: University of British Columbia
Year: 2009

description: This thesis contains two movements. In the first chapter, I evaluate the Apostle Paul's self-presentation in the city of Corinth (as reconstructed through his Corinthian correspondence). Employing the insights of recent scholarship on gender in antiquity, I arrive at the conclusion that Paul's deficiency as a public speaker, his unnamed physical affliction, and possibly his circumcision combined to feminize his image. All three of these characteristics contravene the Greco-Roman canons of masculine appearance and deportment. And, although the social situation in Corinth is by no means clear, it appears that some were challenging Paul's leadership on the basis of his damaged masculinity. In chapters 2 and 3, I explore one element of the Apostle's self-presentation that may have ameliorated his problematic image: sexual renunciation. Self-control in the culture of antiquity was closely associated with the masculine activity par excellence, control over others. Thus, by simply practicing this virtue, Paul was making a meaningful statement both about his body and about his ability to lead. I go on, however, to identify the places in 1 Corinthians 7 (Paul's only extended treatment of marriage and celibacy) where he diverges from classical models of ascetic practice. I contend that these very alterations to the meaning of self-control further rehabilitate his damaged masculinity. This thesis is intended to be, not only a contribution to the social history of early Christianity, but also part of a broad movement in contemporary scholarship to destabilize the foundations of 'masculinity' in the West.

description: Japanese consumers are sophisticated, highly conscious of food quality and safety, and willing to pay for attributes they believe define a high-quality, safe product. A recent series of domestic and international food safety crises have elevated the importance of meat safety among Japanese consumers. The Japanese government and food industry are implementing new policies and systems intended to assure consumers that the food supply is safe and wholesome. Given that these systems tend to focus heavily on consumer assurance programs and traceability, this paper examines the demand for such programs from the perspective of Japanese meat importers, processors, and retailers. The paper discusses Japan's recent history of food safety crises, some of the consumer assurance programs already in use in retail outlets, the potential demand for assurance programs for imported products, and the ability of U.S. and other exporters to provide such assurances.

description: We computed a set of structures which appear in the four-point function of protected operators of dimension two in $\mathcal{N}=4$ Super Yang Mills with $SU(N)$ gauge group, at any order in a large $N$ expansion. They are determined only by leading order CFT data. By focusing on a specific limit, we made connection with the dual supergravity amplitude in flat space, where such structures correspond to iterated $s$-cuts. We made several checks and we conjecture that the same interpretation holds for supergravity amplitudes on $AdS_5 \times S^5$.

Solving parametric systems of polynomial equations over the reals through Hermite matrices

description: We design a new algorithm for solving parametric systems having finitely many complex solutions for generic values of the parameters. More precisely, let $f = (f_1, \ldots, f_m)\subset \mathbb{Q}[y][x]$ with $y = (y_1, \ldots, y_t)$ and $x = (x_1, \ldots, x_n)$, $V\subset \mathbb{C}^{t+n}$ be the algebraic set defined by $f$ and $π$ be the projection $(y, x) \to y$. Under the assumptions that $f$ admits finitely many complex roots for generic values of $y$ and that the ideal generated by $f$ is radical, we solve the following problem. On input $f$, we compute semi-algebraic formulas defining semi-algebraic subsets $S_1, \ldots, S_l$ of the $y$-space such that $\cup_{i=1}^l S_i$ is dense in $\mathbb{R}^t$ and the number of real points in $V\cap π^{-1}(η)$ is invariant when $η$ varies over each $S_i$. This algorithm exploits properties of some well chosen monomial bases in the algebra $\mathbb{Q}(y)[x]/I$ where $I$ is the ideal generated by $f$ in $\mathbb{Q}(y)[x]$ and the specialization property of the so-called Hermite matrices. This allows us to obtain compact representations of the sets $S_i$ by means of semi-algebraic formulas encoding the signature of a symmetric matrix. When $f$ satisfies extra genericity assumptions, we derive complexity bounds on the number of arithmetic operations in $\mathbb{Q}$ and the degree of the output polynomials. Let $d$ be the maximal degree of the $f_i$'s and $D = n(d-1)d^n$, we prove that, on a generic $f=(f_1,\ldots,f_n)$, one can compute those semi-algebraic formulas with $O^~( \binom{t+D}{t}2^{3t}n^{2t+1} d^{3nt+2(n+t)+1})$ operations in $\mathbb{Q}$ and that the polynomials involved have degree bounded by $D$. We report on practical experiments which illustrate the efficiency of our algorithm on generic systems and systems from applications. It allows us to solve problems which are out of reach of the state-of-the-art.
The mechanical response of semiflexible networks to localized perturbations

description: Previous research on semiflexible polymers including cytoskeletal networks in cells has suggested the existence of distinct regimes of elastic response, in which the strain field is either uniform (affine) or non-uniform (non-affine) under external stress. Associated with these regimes, it has been further suggested that a new fundamental length scale emerges, which characterizes the scale for the crossover from non-affine to affine deformations. Here, we extend these studies by probing the response to localized forces and force dipoles. We show that the previously identified nonaffinity length [D.A. Head et al. PRE 68, 061907 (2003).] controls the mesoscopic response to point forces and the crossover to continuum elastic behavior at large distances.

description: We present the first ALMA survey of protoplanetary discs at 3 mm, targeting 36 young stellar objects in the Lupus star-forming region with deep observations (sensitivity 20-50 microJy/beam) at ~0.35" resolution (~50 au). Building on previous ALMA surveys at 0.89 and 1.3 mm that observed the complete sample of Class II discs in Lupus at a comparable resolution, we aim to assess the level of grain growth in the relatively young Lupus region. We measure 3 mm integrated fluxes, from which we derive disc-averaged 1-3 mm spectral indices. We find that the mean spectral index of the observed Lupus discs is $α_\mathrm{1-3 mm}=2.23\pm0.06$, in all cases $α_\mathrm{1-3 mm}<3.0$, with a tendency for larger spectral indices in the brightest discs and in transition discs. Furthermore, we find that the distribution of spectral indices in Lupus discs is statistically indistinguishable from that of the Taurus and Ophiuchus star-forming regions. Assuming the emission is optically thin, the low values $α_\mathrm{1-3 mm}\leq 2.5$ measured for most discs can be interpreted with the presence of grains larger than 1 mm. The observations of the faint discs in the sample can be explained without invoking the presence of large grains, namely through a mixture of optically thin and optically thick emission from small grains. However, the bright (and typically large) discs do inescapably require the presence of millimeter-sized grains in order to have realistic masses. Based on a disc mass argument, our results challenge previous claims that the presence of optically thick sub-structures may be a universal explanation for the empirical millimeter size-luminosity correlation observed at 0.89 mm.
