description: We study the effects of rounding on the moments of random variables. Specifically, given a random variable $X$ and its rounded counterpart $\operatorname{rd}(X)$, we study $|\mathbb{E}[X^k] - \mathbb{E}[\operatorname{rd}(X)^{k}]|$ for non-negative integer $k$. We consider the case that the rounding function $\operatorname{rd} : \mathbb{R}\to\mathbb{F}$ corresponds either to (i) rounding to the nearest point in some discrete set $\mathbb{F}$ or (ii) rounding randomly to either the nearest larger or smaller point in this same set with probabilities proportional to the distances to these points. In both cases, we show, under reasonable assumptions on the density function of $X$, how to compute a constant $C$ such that $|\mathbb{E}[X^k] - \mathbb{E}[\operatorname{rd}(X)^{k}]| < Cε^2$, provided $|\operatorname{rd}(x) - x| \leq ε\: E(x)$, where $E : \mathbb{R} \to \mathbb{R}_{\geq 0}$ is some fixed positive piecewise linear function. Refined bounds for the absolute moments $\mathbb{E}[ |X^k-\operatorname{rd}(X)^{k}|]$ are also given.

description: In the worldwide endeavor for disruptive quantum technologies, germanium is emerging as a versatile material to realize devices capable of encoding, processing, or transmitting quantum information. These devices leverage special properties of the germanium valence-band states, commonly known as holes, such as their inherently strong spin-orbit coupling and the ability to host superconducting pairing correlations. In this Review, we initially introduce the physics of holes in low-dimensional germanium structures with key insights from a theoretical perspective. We then examine the material science progress underpinning germanium-based planar heterostructures and nanowires. We review the most significant experimental results demonstrating key building blocks for quantum technology, such as an electrically driven universal quantum gate set with spin qubits in quantum dots and superconductor-semiconductor devices for hybrid quantum systems. We conclude by identifying the most promising prospects toward scalable quantum information processing.
Non-perturbative definition of five-dimensional gauge theories on the R^4 x S^1/Z_2 orbifold

description: We construct a Z_2 orbifold projection of SU(N) gauge theories formulated in five dimensions with a compact fifth dimension. We show through a non-perturbative argument that no boundary mass term for the Higgs field, identified with some of the fifth dimensional components of the gauge field, is generated, which would be quadratically divergent in the five-dimensional ultraviolet cutoff. This opens the possibility of studying these theories non-perturbatively in order to establish if they can be used as effective weakly interacting theories at low energies. We make preparations for a study on the lattice. In particular we show that only Dirichlet boundary conditions are needed, which specify the breaking pattern of the gauge group at the orbifold fixpoints.

Electroweak-boson production in p-Pb and Pb-Pb collisions at the LHC with ALICE
Creators: name: Taillepied, Guillaume
Publisher: name: arXiv
Year: 2020
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: Electroweak bosons are sensitive probes of the initial state of heavy-ion collisions, of which a precise knowledge is required in order to disentangle initial state effects from phenomena induced by the presence of the quark--gluon plasma (QGP). The production rate of the Z and W$^\pm$ bosons is especially sensitive to the nuclear modification of the Parton Distribution Functions (PDF), and the muonic decays (Z $\rightarrow μ^+μ^-$ and W$^\pm \rightarrow μ^\pm ν$) offer medium-blind processes carrying this information to the detector where it can be directly collected. In this contribution, new measurements of electroweak bosons in p--Pb collisions at $\sqrt{s_{_{\rm NN}}}$ = 8.16 TeV and Pb--Pb collisions at $\sqrt{s_{_{\rm NN}}}$ = 5.02 TeV measured by the ALICE Collaboration are reported. The data are collected at forward rapidity with the ALICE muon spectrometer and are compared to theoretical predictions with and without including nuclear modifications.

description: We investigate electron charge decoherence in a laterally-coupled single-electron semiconductor double quantum dot through electron-phonon interaction. We analytically and numerically evaluate the relaxation and dephasing rates due to electron coupling to both acoustic and optical phonons, and explore the system parameter space in terms of interdot distance, strength of single-dot confinement, and inter-dot coupling strength. Our numerical results show that the electron scattering rates are strongly dependent on the strength of the electron confinement and the size of the system. In addition, although the most dominant factor that determines the charge decoherence rate is the energy splitting between the charge qubit states, the details of the double dot configuration is also very important.

Envisioning the right : caricature and the "Action franca̜ise", 1920-1926
Creators: name: Cantor, Anthony Jay
Publisher: name: University of British Columbia
Year: 2009

description: Between 1920 and 1926, Jehan Sennep, later a prominent French cartoonist and journalist of the Right, published cartoons in the "Action française", the journal of the eponymous French monarchist and integral nationalist movement led by Charles Maurras and Leon Daudet. Cartoons illuminate how cultural products intersect with ideas in the formation of a discursive set of conditions understood as "reality." This allows for a deeper understanding of the culture in which Action Francaise ideology acquired meaning by revealing the images and symbols that, in furthering this ideology, resonated or were expected to resonate with the public. The key thing for Sennep was to convey meaning through the invocation of ideas, assumptions and stereotypes that were current at the time. Caricature permitted him to tell detailed stories about the state of French culture in a one-panel format by relying on shared associations. Sennep relied on "everyday knowledge" in creating his cartoons. His work reveals a discourse surrounding such aspects of the everyday—that is, of the dominant "common knowledge"—as gender, through feminisation, the rural/urban or peasant/city denizen dichotomy, phobias, through motifs of infestation, and empire or colonial subjects. I will interpret Sennep's pictures of the nation and identify the exact nature of the threat he perceived from internal and external enemies, showing that fears about the French nation centred on the potential danger posed by elements in French society and government that were deemed not truly to belong. Even his depiction of external enemies, such as Germany or international communism, can be shown to reveal a preoccupation with internal elements. In showing this and assessing the recurrent themes, I will discuss what the symbols reveal about the culture in which they had currency and the cultural and intellectual debates that raged at the time and helped structure Sennep's symbolic language.

description: This research is a result of the CAP-IRE project which objective is the understanding farmer’s reactions under CAP scenarios by 2020. In particular this research aims to analyze the role of the current CAP design on the farmer’s decision process focusing on several environmental issues. The analysis is based on 2,360 observations of household farmers across 11 cases study in 9 EU countries. Intended responses of farmers to the CAP reforms are analyzed by logistic model regression. According to the results CAP scenarios would influence farmer’s decision on fertilizers and pesticides, as well as water use, while the highest effect is found for decisions on number of animal rearing on the farm. Factors determining reaction to the CAP scenario are monetary and non-monetary, as well as structural and spatial. CAP role appears to be non univocal and strongly case-specific, as it substantially differs across regions according to their socio-economic structure
Thermodynamical property of entanglement entropy and deconfinement phase transition

description: We analyze the holographic entanglement entropy in a soliton background with Wilson lines and derive a relation analogous to the first law of thermodynamics. The confinement/deconfinement phase transition occurs due to the competition of two minimal surfaces. The entropic c function probes the confinement/deconfinement phase transition. It is sensitive to the degrees of freedom (DOF) smaller than the size of a spatial circle. When the Wilson line becomes large, the entropic c function becomes non-monotonic as a function of the size and does not satisfy the usual c-theorem. We analyze the entanglement entropy for a small subregion and the relation analogous to the first law of thermodynamics. For the small amount of Wilson lines, the excited amount of the entanglement entropy decreases from the ground state. It reflects that confinement decreases degrees of freedom. We finally discuss the second order correction of the holographic entanglement entropy.

description: We analyse the stochastic dynamics of a bistable system under the influence of time-delayed feedback. Assuming an asymmetric potential, we show the existence of a regime in which the systems dynamic displays excitability by calculating the relevant residence time distributions and correlation times. Experimentally we then observe this behaviour in the polarization dynamics of a vertical cavity surface emitting laser with opto-electronic feedback. Extending these observations to two-dimensional systems with dispersive coupling we finally show numerically that delay induced excitability can lead to the appearance of propagating wave-fronts and spirals.

description: Korean consumers' willingness to accept (WTA) for GM food are studied in this paper. This study compares hypothetical and nonhypothetical responses to choice experiment questions. We test for hypothetical bias in a choice experiment involving GM rice with differing characteristic attributes and multinomial logit model is applied to predict the estimated results. In general, hypothetical responses predicted higher probabilities of purchasing GM rice than nonhypothetical responses. Thus, hypothetical choices overestimate willingness to accept for GM rice. The results of this paper could contributes to government's GM food policies and subsequent studies, also improving economic welfare of farmers and consumers.

description: Rapid growth has been observed in the fresh blueberry market since 2000, but at the same time, there is no obvious consumption increase in the market for frozen blueberries. In this study, we analyze the different consumer structures in the fresh and frozen blueberry markets by classifying consumers into “buyers”, “potential buyers” and “non-buyers” of blueberries. A double hurdle count data model is used. The results show that while the fresh blueberry market is mainly composed of buyers, most of the consumers in the frozen blueberry market are non-buyers. The difference in growth trends may be due to the fact that it is more difficult to convert non-buyers to buyers than to increase consumption of buyers.

Theory of Supercurrent in Superconductors
Creators: name: Koizumi, Hiroyasu

Publisher: name: arXiv
Year: 2020
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: In the standard theory of superconductivity, the origin of superconductivity is the electron-pairing. The induced current by a magnetic field is calculated by the linear response to the vector potential, and the supercurrent is identified as the dissipationless flow of the paired-electrons, while single electrons flow with dissipation. This supercurrent description suffers from the following serious problems: 1) it contradicts the reversible superconducting-normal phase transition in a magnetic field observed in type I superconductors; 2) the gauge invariance of the supercurrent induced by a magnetic field requires the breakdown of the global $U(1)$ gauge invariance, or the non-conservation of the particle number; 3) the explanation of the ac Josephson effect is based on the boundary condition that is different from the real experimental one. We will show that above problems are resolved if the supercurrent is attributed to the collective mode arising from the Berry connection for many-body wave functions. The problem 1) is resolved by attributing the appearance and disappearance of the supercurrent to the abrupt appearance and disappearance of topologically-protected loop currents produced by the Berry connection; the problem 2) is resolved by assigning the non-conserved number to that for the particle number participating in the collective mode produced by the Berry connection; and the problem 3) is resolved by identifying the relevant phase in the Josephson effect is that arising from the Berry connection, and using the modified Bogoliubov transformation that conserves the particle number.

description: The objective of the research in this study is to evaluate the pricing and market conduct of milk manufacturers and retailers. Using data from a U.S. Midwestern state, we estimate a random coefficient logit demand model (RCL) to empirically investigate a range of possible scenarios in the milk supply chain. These include vertical leader-follower model with underlying Bertrand-Nash pricing, models allowing for nonlinear pricing contracts, and collusion scenarios at various levels in the supply chain. This study contributes to the literature in the following ways. First, it generalizes the RCL demand model via Box-Cox power transformation. While previous studies rely on ad hoc specified linear indirect utility, this procedure allows data to determine the functional form of utility. Power transformation parameters cannot be obtained analytically with product-level data, given that consumer choices are unobserved. We propose an algorithm to estimate the transformation and consumer heterogeneous taste parameters sequentially. The model is identified using annual variation in consumer demographics along with cross-sectional and time series variation in milk consumption. Finally, the milk choice set is allowed to vary across markets. It should be mentioned that jointly estimating the manufacturing sector, the vertical channel, and the retail sector will more likely yield reliable estimates of structural parameters vis-à-vis studies investigating food supply chain sectors in isolation. Several key results are obtained from the research. First, the estimate of demand “superelasticity”suggests that retailers have incentives to adjust retail markups to enhance their market power. Next, supply selection bias associated with imposing restriction on the demand-side framework is shown to have formidable policy implications. Namely, empirical results from the general demand show that retailers are more powerful than they would appear otherwise. In the face of high concentration and a small presence of Wall-Mart in these markets this seems a plausible scenario.

description: Formulation of the Penrose inequality becomes ambiguous when the past and future apparent horizons do cross. We test numerically several natural possibilities of stating the inequality in punctured and boosted single- and double- black holes, in a Dain-Friedrich class of initial data and in conformally flat spheroidal data.The Penrose inequality holds true in vacuum configurations for the outermost element amongst the set of disjoint future and past apparent horizons (as expected)and (unexpectedly) for each of the outermost past and future apparent horizons, whenever these two bifurcate from an outermost minimal surface, regardless of whether they intersect or remain disjoint. In systems with matter the conjecture breaks down only if matter does not obey the dominant energy condition.

description: Using detailed plant-level manufacturing Census data from the Colombian Agri-food industries, we show that exports raise plant-level productivity by about 15 to 20 percent. However, the estimates reveal that efficiency in plants that become persistent exporters, i.e. plants that service foreign markets at least 30 percent of the time during our sample years 1981-1991, increases about 30 percent upon their entry into foreign markets, while productivity in plants that become only occasional exporters does not change at all. Hence, the positive impact of exports on productivity for is driven by the large positive impact on persistent exporters. To identify the effect of exports on plant-level productivity we employ the Levinsohn-Petrin (2003) measure of total factor productivity and a difference-in-differences propensity score matching estimator. The estimates reveal that productivity in plants that become persistent exporters, i.e. plants that service foreign markets at least 30 percent of the time during our sample years 1981-1991, rises about 30 percent upon their entry into foreign markets. Productivity in plants that become only occasional exporters, on the other hand, does not change. We perform a number of robustness checks, all of which confirm our baseline results.

description: Higgs inflation is known to be a minimal extension of the Standard Model allowing for the description of the early Universe inflation. This model is considered as an effective field theory since it has a relatively low cutoff scale, thus requiring further extensions to be a valid description of the reheating phase. We present a novel unified approach to the problem of unitarization and UV completion of the Higgs inflation model without introducing new massive degrees of freedom. This approach is based on an analytic infinite derivative modification of the Higgs field kinetic term. We construct a unitary non-local UV completion of the original Higgs inflation model while the inflationary stage is kept stable with respect to quantum corrections.

description: A growing share of water pollution in the U.S. can be attributed to nonpoint sources (USEPA 2002). Some of this trend can be attributed to declining point source (PS) emissions as a result of regulation under the Clean Water Act (CWA). However, fertilizer-intensive practices used to improve agricultural productivity over recent decades have also increased nitrate loads and resulted in water quality impairments. Nonpoint source (NPS) pollution from agricultural practices is generally exempt from federal regulation. However, some voluntary programs allow point sources subject to the CWA’s effluent limitations to meet their standards by purchasing offset credits reflecting reductions in NPS discharges to the same waters (USEPA 2004). Such water quality trading (WQT) programs have been implemented in a number of states to reduce pollution abatement costs (Breetz et al 2004). In this setting, NPS supply pollution abatement when they implement best management practices (BMP) that reduce nutrient loads, and the cost of BMPs form a supply curve for credits. WQT programs are supported by the EPA as an important means for efficiently pursuing water quality goals (USEPA 2003a). Among the BMPs available for water quality management, riparian buffer strips have proven effective in mitigating the movement of nutrients and other pollutants into surface waters (Qiu et al 2006). Estimates of riparian buffer costs would be valuable for developing policy related to WQT and other conservation programs. This paper estimates the annual costs of buffer strips in six counties in the Lower Kentucky River Basin, as part of a project evaluating the feasibility of WQT programs in that area.
Laplacian modes probing gauge fields

description: We show that low-lying eigenmodes of the Laplace operator are suitable to represent properties of the underlying SU(2) lattice configurations. We study this for the case of finite temperature background fields, yet in the confinement phase. For calorons as classical solutions put on the lattice, the lowest mode localizes one of the constituent monopoles by a maximum and the other one by a minimum, respectively. We introduce adjustable phase boundary conditions in the time direction, under which the role of the monopoles in the mode localization is interchanged. Similar hopping phenomena are observed for thermalized configurations. We also investigate periodic and antiperiodic modes of the adjoint Laplacian for comparison. In the second part we introduce a new Fourier-like low-pass filter method. It provides link variables by truncating a sum involving the Laplacian eigenmodes. The filter not only reproduces classical structures, but also preserves the confining potential for thermalized ensembles. We give a first characterization of the structures emerging from this procedure.

description: We study the prospects for deducing constraints on the interaction of charmed baryons with nucleons from measurements of two-particle momentum correlation functions for $Λ_c p$. The correlation functions are calculated for $Λ_c N$ and $Σ_c N$ interactions that have been extrapolated from lattice QCD simulations at unphysical masses of $m_π=410-570$ MeV to the physical point using chiral effective field theory as guideline. In addition, we consider phenomenological $Y_c N$ models from the literature to explore the sensitivity of the results to the properties of the interaction in detail. We find that a measurement of the $Λ_c p$ correlation functions could indeed allow one to discriminate between strongly attractive $Λ_c N$ forces, as predicted by some phenomenological models, and a weakly attractive interaction as suggested by the presently available lattice simulations.

description: We evaluate the impact of USDA’s low-cost broadband loan programs on the U.S. agricultural sector. The broadband loan programs increase access to high-speed internet in recipient communities, which can raise farm sales by increasing both farm output and prices received by producers. Further, high-speed internet may drive down costs by providing information on cheaper inputs and better management practices, leading to an overall improvement in farm profits. Using data from the 1997, 2002, and 2007 U.S. Census of Agriculture, we employ a panel difference-in-differences estimator, as well as a difference-in-differences propensity score matching estimator, to show that the two USDA broadband loan programs have positive impacts on farm sales, expenditure, and profits. The positive effects for crops are larger than those for livestock and animal products.

description: Gamma radiation from the Crab pulsar wind nebula (PWN) shows significant variability at $\sim100$ MeV energies, recently revealed with spaceborne gamma-ray telescopes. Here we report the results of a systematic search for gamma-ray flares using a 7.4-year data set acquired with the Fermi Large Area Telescope. Analyzing the off-pulse phases of the Crab pulsar, we found seven previously unreported low-intensity flares ("small flares"). The "small flares'' originate from the variable synchrotron component of the Crab PWN and show clearly different features from the steady component of the Crab PWN emission. They are characterized by larger fluxes and harder photon indices, similar to previously reported flares. These flares show day-scale time variability and imply a strong magnetic field of $B_{\rm min}\approx 1~\mathrm{mG}$ at the site of the gamma-ray production. This result seems to be inconsistent with the typical values revealed with modeling of the non-thermal emission from the nebula. The detection of the "small flares'' gives a hint of production of gamma rays above $100$ MeV in a part of the nebula with properties which are different from the main emitters, e.g., due to bulk relativistic motion.

description: The paper presents a result which relates connectedness of the interaction graphs in a multi-agent systems with the capability for global convergence to a common equilibrium of the system. In particular we extend a previously known result by Moreau by including the possibility of arbitrary bounded time-delays in the communication channels and relaxing the convexity of the allowed regions for the state transition map of each agent.

description: We consider a $[ud]^2\bar{s}$ current, in the finite-density QCD sum rule approach, to investigate the scalar and vector self-energies of the recently observed pentaquark state $Θ^+(1540)$, propagating in nuclear mater. We find that, opposite to what was obtained for the nucleon, the vector self-energy is negative, and the scalar self-energy is positive. There is a substantial cancellation between them resulting in an attractive net self-energy of the same order as in the nucleon case.

Using term proximity measures for identifying compound concepts : an expolatory study
Creators: name: Yin, Nawei
Publisher: name: University of British Columbia
Year: 2009

description: With the rapid development of information technology, individuals using the technology are liable to be overwhelmed by the excessive amounts of information available when conducting online (local or remote) document searches. It is important therefore that users specify the correct search terms. However, a user does not always know which terms to use and often the same idea can be described by different terms. Constructing lists of possible search terms for different domains would require a very substantial effort by experts in each domain. To alleviate these problems, automated techniques can be valuable to extract concepts and meaningful phrases for specific domains. This work is an exploratory study of automated extraction of compound concepts from a collection of documents in a specific domain. The concept-extraction methods used in this study employed clustering techniques based on distance measures that reflect term affinity statistics rather than techniques based on similarity measures adopted in most previous works. The study compared the effects of different methods of calculating affinities, depending on the sizes of textual units where terms co-occur and on directionality and asymmetry between terms. The accounting context was used as a case study to provide the data. An accounting expert evaluated the resulting clusters produced by the clustering program. As demonstrated by our results, the method identified meaningful accounting compound concepts and phrases. The research also indicated which affinity types generated better results. For example, affinities based on occurrence of terms within a document produced the poorest results. There was a significant manual effort involved in "preprocessing" the data prior to compound concept identification. However, we believe the techniques explored might be useful for users to search relevant information within individual domains and can be extended to support the construction of domain-specific thesauri.

description: We report on an investigation of Ruppeiner curvature $R_U$ for $(d+1)$-dimensional hyperbolic black holes in anti-de Sitter spacetimes and its connection with Renormalization Group (RG) flows in the dual d-dimensional conformal field theories (CFTs) in Minkowski spacetimes. A repulsive type interaction among microstructures is found, which is weaker for positive mass black holes and grows stronger for negative mass black holes at low temperatures. In particular, we show that $R_U$ evaluated along a zero mass curve is a universal constant, depending only on the dimension of space-time. The extremal black holes are pointed out to have a positive Ruppeiner curvature irrespective of their horizon topology.

description: Crop rotation systems are an important part of agricultural production for managing pests, diseases, and soil fertility. Recent interest in sustainable agriculture focuses on low input-use practices which require knowledge of the underlying dynamics of production and rotation systems. Polices to limit chemical application depending on proximity to waterways and flood management require field-level data and analysis. Additionally, supply elasticity estimates based on crop production as independent activities omit the dynamic effects of a cyclical rotation. We estimate a dynamic programming model of crop rotation which incorporates yield and cost inter-temporal effects in addition to field-specific factors including salinity and soil quality. Using an Optimal Matching algorithm from the Bioinformatics literature we determine empirically observed rotations using a geo-referenced panel dataset of 14,000 fields over 13 years. We estimate the production parameters which satisfy the Euler Equations of the field-level rotation problem and solve an empirically observed four-crop rotation.
