description: I present a calculation of QCD radiative corrections to charged Higgs production via the process bg -> tH-. I show that the cross section is dominated by soft-gluon corrections, which are computed through next-to-next-to-leading order. Results for charged Higgs production at the LHC are presented, including the dependence of the cross section on the charged Higgs mass, the top quark mass, the factorization and renormalization scales, and tan beta.

description: Let $G$ be a simple graph on $n$ vertices and $J_G$ denote the corresponding binomial edge ideal in $S = K[x_1, \ldots, x_n, y_1,\ldots, y_n].$ We prove that the Castelnuovo-Mumford regularity of $J_G$ is bounded above by $c(G)+1$ when $G$ is a quasi-block graph or semi-block graph. We give another proof of Saeedi Madani-Kiani regularity upper bound conjecture for chordal graphs. We obtain the regularity of binomial edge ideals of Jahangir graphs. Later, we establish a sufficient condition for Hibi-Matsuda conjecture to be true.

description: Graphing univariate distributions is central to both statistical graphics, in general, and Stata’s graphics, in particular. Now that Stata 8 is out, a review of official and user-written commands is timely. The emphasis here is on going beyond what is obviously and readily available, with pointers to minor and major trickery and various user-written commands. For plotting histogram-like displays, kernel-density estimates and plots based on distribution functions or quantile functions, a large variety of choices is now available to the researcher.

description: The rheological properties for dilute and moderately dense granular binary mixtures of smooth, inelastic hard disks/spheres under uniform shear flow in steady state conditions are reported. The results are based on the Enskog kinetic theory, numerically solved by a dense gas extension of the Direct Simulation Monte Carlo method for dilute gases. These results are confronted to the ones also obtained by performing molecular dynamics simulations with very good agreement for the lower densities and higher coefficients of restitution. It appears that the range of densities for which the Enskog equation applies decreases with increasing dissipation.

description: This qualitative research examined the extent to which there is a need for the new term "Socially and Emotionally Intelligent usage of Technology" (SEIuT). The research includes 15 participants who were selected through a combination of convenience and purposeful sampling. The researcher used 4 main interview questions to guide the data collection process. The questions were designed to collect data on respondents' opinions, perspectives, and experiences related to youth' daily ICT use and its influence on their social and emotional skills. Our findings indicate the need for both a SEIuT term and a preventive program to support SEIuT. The research will show that there are several indicators that demonstrate this need, such as problematic ICT usage, a growing reliance on ICT for socialization purposes, lack of SEI skills in ICT usage and others. Based on this research, SEIuT consists of 7 skills: Ability to use ICT as a tool, Disciplined iCT usage, and 5 SEI related skills: Self-awareness, Self- management, Social awareness, Relationship skills and Responsible decision making skills in ICT usage. Our research aims to start an investigation into Socially and Emotionally Intelligent usage of Technology (SEIUT) and the potential for creating preventative programs in support of SEIuT.

description: Mounting privacy legislation calls for the preservation of privacy in speech technology, though solutions are gravely lacking. While evaluation campaigns are long-proven tools to drive progress, the need to consider a privacy adversary implies that traditional approaches to evaluation must be adapted to the assessment of privacy and privacy preservation solutions. This paper presents the first step in this direction: metrics. We introduce the zero evidence biometric recognition assessment (ZEBRA) framework and propose two new privacy metrics. They measure the average level of privacy preservation afforded by a given safeguard for a population and the worst-case privacy disclosure for an individual. The paper demonstrates their application to privacy preservation assessment within the scope of the VoicePrivacy challenge. While the ZEBRA framework is designed with speech applications in mind, it is a candidate for incorporation into biometric information protection standards and is readily extendable to the study of privacy in applications even beyond speech and biometrics.

description: We discuss models of the modulational instability in a cold exciton system in coupled quantum wells. One mechanism involves exciton formation in a photoexcited electron-hole system in the presence of stimulated binding processes which build up near exciton degeneracy. It is shown that such processes may give rise to Turing instability leading to a spatially modulated state. The structure and symmetry of resulting patterns depend on dimensionality and symmetry. In the spatially uniform 2d electron-hole system, the instability leads to a triangular lattice pattern while, at an electron-hole interface, a periodic 1d pattern develops. Wavelength selection mechanism is analyzed, revealing that the transition is abrupt (type I) for the uniform 2d system, and continuous (type II) for the electron-hole interface. Another mechanism that could possibly drive the instability involves long-range attraction of the excitons. We illustrate how such an interaction can result from current induced by exciton recombination ('plasmon wind'), derive stability criterion, and discuss likelihood of such a scenario.

description: Geometric phase may enable inherently fault-tolerant quantum computation. However, due to potential decoherence effects, it is important to understand how such phases arise for {\it mixed} input states. We report the first experiment to measure mixed-state geometric phases in optics, using a Mach-Zehnder interferometer, and polarization mixed states that are produced in two different ways: decohering pure states with birefringent elements; and producing a nonmaximally entangled state of two photons and tracing over one of them, a form of remote state preparation.

On the two separate decay time scales of a detonation wave modelled by the Burgers equation and their relation to its chaotic dynamics

Year: 2020
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: This study uses a simplified detonation model to investigate the behaviour of detonations with galloping-like pulsations. The reactive Burgers equation is used for the hydrodynamic equation, coupled to a pulsed source whereby all the shocked reactants are simultaneously consumed at fixed time intervals. The model mimics the short periodic amplifications of the shock front followed by relatively lengthy decays seen in galloping detonations. Numerical simulations reveal a saw tooth evolution of the front velocity with a period-averaged detonation speed equal to the Chapman-Jouguet velocity. The detonation velocity exhibits two distinct groups of decay time scales, punctuated by reaction pulses. At each pulse, a rarefaction wave is created at the reaction front's last position. A characteristic investigation reveals that characteristics originating from the head of this rarefaction take 1.57 periods to reach and attenuate the detonation front, while characteristics at the tail take an additional period. The leading characteristics are amplified twice, by passing through the reaction fronts of subsequent pulses, before arriving at the shock front, whilst the trailing characteristics are amplified three times. This leads to the two distinct groups of time scales seen in the detonation front speed.

description: The behavior of a driven granular gas in a container consisting of $M$ connected compartments is studied employing a microscopic kinetic model. After obtaining the governing equations for the occupation numbers and the granular temperatures of each compartment we consider the various dynamical regimes. The system displays interesting analogies with the ordering processes of phase separating mixtures quenched below the their critical point. In particular, we show that below a certain value of the driving intensity the populations of the various compartments become unequal and the system clusterizes. Such a phenomenon is not instantaneous, but is characterized by a time scale, $τ$, which follows a Vogel-Vulcher exponential behavior. On the other hand, the reverse phenomenon which involves the ``evaporation'' of a cluster due to the driving force is also characterized by a second time scale which diverges at the limit of stability of the cluster.

description: We propose a novel mixture-of-experts class to optimize computer vision models in accordance with data transfer limitations at test time. Our approach postulates that the minimum acceptable amount of data allowing for highly-accurate results can vary for different input space partitions. Therefore, we consider mixtures where experts require different amounts of data, and train a sparse gating function to divide the input space for each expert. By appropriate hyperparameter selection, our approach is able to bias mixtures of experts towards selecting specific experts over others. In this way, we show that the data transfer optimization between visual sensing and processing can be solved as a convex optimization problem.To demonstrate the relation between data availability and performance, we evaluate biased mixtures on a range of mainstream computer vision problems, namely: (i) single shot detection, (ii) image super resolution, and (iii) realtime video action classification. For all cases, and when experts constitute modified baselines to meet different limits on allowed data utility, biased mixtures significantly outperform previous work optimized to meet the same constraints on available data.

description: Some properties of $d$-dimensional disordered models with long-range random hopping amplitudes are investigated numerically at criticality. We concentrate on the correlation dimension $d_2$ (for $d=2$) and the nearest level spacing distribution $P_c(s)$ (for $d=3$) in both the weak ($b^d \gg 1$) and the strong ($b^d \ll 1$) coupling regime, where the parameter $b^{-d}$ plays the role of the coupling constant of the model. It is found that (i) the extrapolated values of $d_2$ are of the form $d_2=c_db^d$ in the strong coupling limit and $d_2=d-a_d/b^d$ in the case of weak coupling, and (ii) $P_ (s)$ has the asymptotic form $P_c(s)\sim\exp (-A_ds^α)$ for $s\gg $, with the critical exponent $α=2-a_d/b^d$ for $b^d \gg 1$ and $α=1+c_d b^d$ for $b^d \ll 1$. In these cases the numerical coefficients $A_d$, $a_d$ and $c_d$ depend only on the dimensionality.

description: While COVID-19 is rapidly propagating around the globe, the need for providing real-time forecasts of the epidemics pushes fits of dynamical and statistical models to available data beyond their capabilities. Here we focus on statistical predictions of COVID-19 infections performed by fitting asymptotic distributions to actual data. By taking as a case-study the epidemic evolution of total COVID-19 infections in Chinese provinces and Italian regions, we find that predictions are characterized by large uncertainties at the early stages of the epidemic growth. Those uncertainties significantly reduce after the epidemics peak is reached. Differences in the uncertainty of the forecasts at a regional level can be used to highlight the delay in the spread of the virus. Our results warn that long term extrapolation of epidemics counts must be handled with extreme care as they crucially depend not only on the quality of data, but also on the stage of the epidemics, due to the intrinsically non-linear nature of the underlying dynamics. These results suggest that real-time epidemiological projections should include wide uncertainty ranges and urge for the needs of compiling high-quality datasets of infections counts, including asymptomatic patients.

We find that static vortex solutions in $2+1D$ do exist. However, the 't Hooft-Polyakov monopole in $3+1D$ is no longer stable, as soon as the chemical potential acquires a finite value. In the case of the Skyrmion, this topological solution still exists for finite $μ$, up to a certain critical value.

description: In this paper, the existing Scheduling Dimension Reduction (SDR) methods for Linear Parameter-Varying (LPV) models are reviewed and a Deep Neural Network (DNN) approach is developed that achieves higher model accuracy under scheduling dimension reduction. The proposed DNN method and existing SDR methods are compared on a two-link robotic manipulator, both in terms of model accuracy and performance of controllers synthesized with the reduced models. The methods compared include SDR for state-space models using Principal Component Analysis (PCA), Kernel PCA (KPCA) and Autoencoders (AE). On the robotic manipulator example, the DNN method achieves improved representation of the matrix variations of the original LPV model in terms of the Frobenius norm compared to the current methods. Moreover, when the resulting model is used to accommodate synthesis, improved closed-loop performance is obtained compared to the current methods.

description: This paper explores the case for believing endogenous reforms to be more developmental than externally-imposed reforms, by drawing on the recent unorthodox experience of cotton sector reform in Burkina Faso. We address questions about reform emergence, feasibility, developmental impact, and sustainability. Our analysis, which carefully incorporates local social and political realities, suggests that the urban elites dominating the Burkinabè state favoured a particular cotton reform process, because it provided them with higher rents; while allowing for some rent distribution to the rural world which secured national consensus around reform. Endogenous reforms, though more feasible, are not necessarily more sustainable over time. In Burkina Faso, the initial reform benefits were eroded after 2006. We interpret this as due to the inability of the new institutional equilibrium to win over the ressure from changed stakeholder incentives, as well as to a loss of responsiveness of the rural leadership to its base.

description: Regulation of nonpoint source pollution often relies in one way or another on policy instruments based on ambient indicators. For well-known reasons, enforcement of ambient-based policies is, at best, limited. If no individual choices or actions are observed, than ambient-based regulation might be the only feasible approach. Often, some relevant individual indicators, such as output or certain inputs, are observable. For such cases, we offer a regulation mechanism that does away with ambient indicators. The mechanism implements the optimal output-abatement-emission allocation and gives rise to the full information outcome when the social cost of transfers is nil. Special attention is given to the regulation of (unobserved) abatement.

description: Vehicular communication systems face significant challenges due to high mobility and rapidly changing environments, which affect the channel over which the signals travel. To address these challenges, neural network (NN)-based channel estimation methods have been suggested. These methods are primarily trained on high signal-to-noise ratio (SNR) with the assumption that training a NN in less noisy conditions can result in good generalisation. This study examines the effectiveness of training NN-based channel estimators on mixed SNR datasets compared to training solely on high SNR datasets, as seen in several related works. Estimators evaluated in this work include an architecture that uses convolutional layers and self-attention mechanisms; a method that employs temporal convolutional networks and data pilot-aided estimation; two methods that combine classical methods with multilayer perceptrons; and the current state-of-the-art model that combines Long-Short-Term Memory networks with data pilot-aided and temporal averaging methods as post processing. Our results indicate that using only high SNR data for training is not always optimal, and the SNR range in the training dataset should be treated as a hyperparameter that can be adjusted for better performance. This is illustrated by the better performance of some models in low SNR conditions when trained on the mixed SNR dataset, as opposed to when trained exclusively on high SNR data.

description: A key issue in the estimation of production functions is the correlation between unobservable productivity shocks and input levels. Profit-maximizing firms respond to positive productivity shocks by expanding output, which requires additional inputs. Negative shocks lead firms to pare back output, decreasing their input usage. Olley and Pakes (1996) develop an estimator that uses investment as a proxy for these unobservable shocks. More recently, Levinsohn and Petrin (2003a) introduce an estimator that uses intermediate inputs as proxies, arguing that intermediates may respond more smoothly to productivity shocks. This paper reviews Levinsohn and Petrin’s approach and introduces a Stata command that implements it.
Hubbard-Kanamori model: spectral functions, negative electron compressibility, and susceptibilities

Publisher: name: arXiv

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

description: The two-orbital Hubbard-Kanamori model is studied using the strong coupling diagram technique. This approach allows one to take into account the interactions of electrons with spin, charge, and orbital fluctuations of all ranges. It was found that, at low temperatures, the model has four regions of the negative electron compressibility, which can lead to charge inhomogeneities with the assistance of phonons. For half-filling, the phase diagram of the model contains regions of the Mott and Slater insulators, bad-metal, and states with spin-polaron peaks. These sharp peaks at the Fermi level are seen in doped states also. A finite Hund coupling leads to a large increase of antiferromagnetic spin correlations with strong suppression of charge and orbital fluctuations near half-filling. For moderate doping, all types of correlations become comparable. They peak at the antiferromagnetic wave vector except for a narrow region with an incommensurate response. Stronger doping destroys all correlations.

The representation of outdoor recreation in land-use planning in British Columbia
Creators: name: Harshaw, Howard W.
Publisher: name: University of British Columbia
Year: 2010

description: The cases of recreation in the Sea-to-Sky Corridor and Peace Foothills in British Columbia are used to explore the issues of the representation of outdoor recreation in land-use planning and the participation of recreationists in land-use planning. The widening array of outdoor recreation activities in high-use areas poses new challenges to the equitable participation of diverse recreation user groups in land-use planning. How well have past land-use planning exercises represented the needs of outdoor recreationists? How well represented do participants of newer recreation activities feel? Moreover, who should represent these diverse groups? There has, to date, been very little research in this area. In an attempt to explore these questions and begin building a theoretical framework for understanding key relationships, this study measures recreationists' perceptions of representation in land-use planning and their participation in land-use planning in the Sea-to-Sky Corridor and Peace Foothills. Relationships between recreation use and socio-economic characteristics and recreationists' participation and perceptions of representation in land-use planning were examined. Moderate levels of perceived representation were found for most recreation groups, although some users seemed unclear about how well they were represented. In sum, some socio-economic characteristics (household income, age, and education) were associated with a person's participation in land-use planning; this influence extended to perceived representation through aspects of social capital, as membership in an outdoor recreation club and degree of recreation specialization were associated with perceived representation. The localness of recreationists played a role in their participation in land-use planning; localness also was associated with perceived representation. Outdoor recreation characteristics (recreation specialization, activity choice, the number of activities participated in, annual participation, and club membership) had an influence on recreationists' likelihood of participation in land-use planning. Logistic regression models suggested that recreation specialization and household income contributed to respondents' perceptions of representation in land-use planning; age, recreation specialization, the number of recreation activities participated in, club membership, and local residence contributed to respondents' likelihood of having been a participant of a land-use planning process. The results of this study support four land-use planning strategies that may assist planners in increasing actual and perceived representation of recreationists.

description: The European Space Agency’s Gaia spacecraft was launched in December 2013 with the aim of making the largest and most precise map of the Milky Way by taking measurements of over one billion astronomical objects. It has a payload of 106 charge-coupled devices (CCDs) to help achieve its objectives. During the pre-flight testing phase of the mission, the non-ionizing energy loss (NIEL) radiation damage on the detectors was identified as a major factor that would affect the science goals of the mission. From analysis of the in-flight data, the degradation of the CCDs from radiation damage, measured as the charge-transfer inefficiency (CTI), was found to be significantly less than what was predicted from the pre-flight on-ground tests.

This thesis further investigates the radiation damage of the Gaia CCDs to more precisely understand the CTI behaviour; this helps to maintain credibility in the pre-flight tests and to better prepare for future space missions. Further in-flight data is analysed and a number of new insights are revealed about the data, related to differences in behaviour between device variants and the nature of radiation damage across Gaia’s focal plane. Different factors that have combined to result in the lower in-flight CTI measurements are also studied with analysis of on-ground data and the use of different simulation models to better understand the datasets. Finally, all these factors are combined together to make an assessment on the CTI differences between Gaia’s in-flight and on-ground CCDs and propose future testing to determine any additional sources of radiation.

description: The field of fashion compatibility learning has attracted great attention from both the academic and industrial communities in recent years. Many studies have been carried out for fashion compatibility prediction, collocated outfit recommendation, artificial intelligence (AI)-enabled compatible fashion design, and related topics. In particular, AI-enabled compatible fashion design can be used to synthesize compatible fashion items or outfits in order to improve the design experience for designers or the efficacy of recommendations for customers. However, previous generative models for collocated fashion synthesis have generally focused on the image-to-image translation between fashion items of upper and lower clothing. In this paper, we propose a novel outfit generation framework, i.e., OutfitGAN, with the aim of synthesizing a set of complementary items to compose an entire outfit, given one extant fashion item and reference masks of target synthesized items. OutfitGAN includes a semantic alignment module, which is responsible for characterizing the mapping correspondence between the existing fashion items and the synthesized ones, to improve the quality of the synthesized images, and a collocation classification module, which is used to improve the compatibility of a synthesized outfit. In order to evaluate the performance of our proposed models, we built a large-scale dataset consisting of 20,000 fashion outfits. Extensive experimental results on this dataset show that our OutfitGAN can synthesize photo-realistic outfits and outperform state-of-the-art methods in terms of similarity, authenticity and compatibility measurements.

description: We consider the spin reorientation transition in a ferromagnetic Heisenberg monolayer with a second order single ion anisotropy as a function of temperature and external field. Up to now analytical methods give satisfying results only for the special case that the external field is aligned parallel to the easy axis of the crystal. We propose a theory based on a generalization of the Callen decoupling, which can be used for arbritrary direction of the external field. Excellent agreement between our results and Quantum Monte Carlo data is found for the field induced reorientation at finite temperatures. Additionally, we discuss the temperature dependence of the transition in detail.

description: To create and sustain a competitive advantage in markets that increasingly value animal welfare attributes, meat companies need to meet public and private production standards while communicating to final consumers through their brands. Data are collected from a representative sample of 460 U.S. residents through an on-line experiment on McDonald’s chicken breast sandwiches and analyzed with Latent Growth Modeling. This study assesses which content of positive brand information effectively mitigates the risk of negative information shocks on animal welfare. On average, brand information has the same positive impact on consumers’ beliefs and attitudes, regardless of whether it is related or unrelated to animal welfare. However, there is strong market segmentation in terms of consumers’ response when exposed to brand information, suggesting that brand managers would benefit from tailoring brand information according to consumers’ age, education, gender and income.
Disk Planet Interactions and Early Evolution in Young Planetary Systems

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: We study and review disk protoplanet interactions using local shearing box simulations. These suffer the disadvantage of having potential artefacts arising from periodic boundary conditions but the advantage, when compared to global simulations, of being able to capture much of the dynamics close to the protoplanet at high resolution for low computational cost. Cases with and without self sustained MHD turbulence are considered. The conditions for gap formation and the transition from type I migration are investigated and found to depend on whether the single parameter M_p R^3/(M_* H^3), with M_p, M_*, R and H being the protoplanet mass, the central mass, the orbital radius and the disk semi-thickness respectively exceeds a number of order unity. We also investigate the coorbital torques experienced by a moving protoplanet in an inviscid disk. This is done by demonstrating the equivalence of the problem for a moving protoplanet to one where the protoplanet is in a fixed orbit which the disk material flows through radially as a result of the action of an appropriate external torque. For sustainable coorbital torques to be realized a quasi steady state must be realized in which the planet migrates through the disk without accreting significant mass. In that case although there is sensitivity to computational parameters, in agreement with earlier work by Masset & Papaloizou (2003) based on global simulations, the coorbital torques are proportional to the migration speed and result in a positive feedback on the migration, enhancing it and potentially leading to a runaway. This could lead to a fast migration for protoplanets in the Saturn mass range in massive disks and may be relevant to the mass period correlation for extrasolar planets which gives a preponderance of sub Jovian masses at short orbital period.

Axinyssa djiferi

description: Axinyssa djiferi sp. nov. Material examined: 24.4. 83 DAK­ 52, at low tide in the mangrove swamp of Saloum which is designated as the type specimen and deposited in the MNHN under the number: MNHN. Several specimens from the same locality in the authors’ collection. Morphology (Fig. 1): The holotype forms a sleeve around the roots of the mangroves close to the bottom. The dimensions are about 10 cm in length and 1­3 cm in thickness. The live specimens have a black surface, and the choanosome is yellow greenish. The surface is raised by conules which are hispid. The surface between the conules is smooth. The consistency is soft. The oscules (3­4 mm in diameter) are clearly visible at the top of fistules of about 1.5­ 2 cm height and 1 cm diameter at the base (Fig. 2). The others specimens are very similar to the type­specimen. The type specimen, collected in April, is in reproduction and shows a wide range of oocytes and embryos from 15 to 20 µm in diameter especially abundant at the base (Figs. 3­4). The sponge is thus viviparous. Skeleton (Figs. 3, 5): Choanosomal skeleton (Fig. 3) composed of ascending tracts of about 50 to 100 µm in diameter which rise the surface. The spicule tracts end in brushes at the surface conules. Single spicules are present between the tracts. In the ectosome, the smallest oxeas constitute the brushes and form a tangential skeleton between the brushes (Fig. 5). Spicules (Figs. 6, 7): Oxeas of the choanosomal tracts are slightly curved, with two regular acerate extremities, and with a clearly visible axial canal (Fig. 6); some of these oxeas are styloid (Fig. 7): 281­567 /10.6­26.5 µm (mean 418 ± 74 /13.6±4.5 µm). Oxeas of the ectosome are straight and acerate (Fig. 6): 101­233 /5.3­10.6 µm (mean 147 ± 31 / 6 ±1.8 µm).
