description: As an important component in steel connections, high-strength bolts have a high stress level and may experience creep deformation at high temperatures. This will lead to great deformation and even failure of steel connections, thus affecting progressive collapse resistance of steel structures. This paper experimentally and numerically investigates the creep behavior of 10.9 high-strength bolts under and after fire. The creep strain-time curves at different temperatures and stress levels were obtained using DIC measurement systems. The micromorphology and failure mechanism of high-strength bolts is examined by SEM. The Field & Field creep model is calibrated against test results, and parametric studies are conducted on T-stub connections. The experimental results show that the creep deformation of high-strength bolts is significant at high temperatures, and the creep strain is positively correlated with temperatures and stress ratios. The numerical results show that the Field & Field model is suitable for characterizing the creep behavior of high-strength bolts under fire situation. The fire resistance of T-stub connections is significantly affected by creep-related parameters. It is necessary to consider the effect of creep for predicting the behavior of high-strength bolts and steel connections, ensuring a safe design.

description: Skyline, aiming at finding a Pareto optimal subset of points in a multi-dimensional dataset, has gained great interest due to its extensive use for multi-criteria analysis and decision making. The skyline consists of all points that are not dominated by any other points. It is a candidate set of the optimal solution, which depends on a specific evaluation criterion for optimum. However, conventional skyline queries, which return individual points, are inadequate in group querying case since optimal combinations are required. To address this gap, we study the skyline computation in the group level and propose efficient methods to find the Group-based skyline (G-skyline). For computing the front $l$ skyline layers, we lay out an efficient approach that does the search concurrently on each dimension and investigates each point in the subspace. After that, we present a novel structure to construct the G-skyline with a queue of combinations of the first-layer points. We further demonstrate that the G-skyline is a complete candidate set of top-$l$ solutions, which is the main superiority over previous group-based skyline definitions. However, as G-skyline is complete, it contains a large number of groups which can make it impractical. To represent the "contour" of the G-skyline, we define the Representative G-skyline (RG-skyline). Then, we propose a Group-based clustering (G-clustering) algorithm to find out RG-skyline groups. Experimental results show that our algorithms are several orders of magnitude faster than the previous work.

description: Recent work has shown that two seemingly different physical mechanisms, namely fracton behavior and confinement, can give rise to non-ergodicity in one-dimensional quantum many-body systems. In this work, we demonstrate an intrinsic link between these two mechanisms by studying the dynamics of one-dimensional confining theories, such as a U(1) gauge theory and a quantum Ising model. We show that, within certain parameter regimes, these models exhibit effective fracton dynamics, characterized by immobility of stable single-particle excitations and free motion of dipolar bound states. By perturbatively integrating out the linearly confining field, we obtain an effective fracton Hamiltonian for the confined charges which exhibits conservation of dipole moment. We discuss an intuitive understanding of these results in terms of the motion of the confining strings, leading to potential extensions to higher dimensions. We thereby interpret recent observations of nonthermal eigenstates and glassy dynamics in confining theories in terms of corresponding results in the fracton literature.

description: The regularity of systolically extremal surfaces is a notoriously difficult problem already discussed by M. Gromov in 1983, who proposed an argument toward the existence of $L^2$-extremizers exploiting the theory of $r$-regularity developed by P. A. White and others by the 1950s. We propose to study the problem of systolically extremal metrics in the context of generalized metrics of nonpositive curvature. A natural approach would be to work in the class of Alexandrov surfaces of finite total curvature, where one can exploit the tools of the completion provided in the context of Radon measures as studied by Reshetnyak and others. However the generalized metrics in this sense still don't have enough regularity. Instead, we develop a more hands-on approach and show that, for each genus, every systolically extremal nonpositively curved surface is piecewise flat with finitely many conical singularities. This result exploits a decomposition of the surface into flat systolic bands and nonsystolic polygonal regions, as well as the combinatorial/topological estimates of Malestein-Rivin-Theran, Przytycki, Aougab-Biringer-Gaster and Greene on the number of curves meeting at most once, combined with a kite excision move. The move merges pairs of conical singularities on a surface of genus $g$ and leads to an asymptotic upper bound $g^{4+ε}$ on the number of singularities.

description: The purpose of this report is to set the basic roadmap for evaluation and testing of the Prismarch platform. The software is being developed and will be released as a minimum viable product to satisfy the development requirements set on previous project deliverables.
 The evaluation consists of two basic components for data gathering. The evaluation plan focuses on the software outputs and deliverables and how these compare against the predefined set of minimum requirements. There is a more technical approach to the evaluation plan and outputs are easier to measure and quantify. The second component is the usability study which aims to measure and quantify the interaction and user experience with the software, in a diversified crowd of users. As an outcome of the evaluation and usability process, a set of measurable quantitative and qualitative outcome measures will be produced, aiming to assess the overall software performance, as well as serve as future input to improve and optimise Prismarch.

description: In a world with two quark flavors and a large number of colors (N_c), the polarized and unpolarized quark distributions in the delta are completely determined by those in the nucleon up to {\cal O}(1/N_c). In particular, we find q_Δ(x) =[(1\pm 2T_z)u_N(x)+ (1\mp 2T_z)d_N(x)]/2 and Δq_Δ(x) =[(5\pm 2T_z)Δu_N(x) + (5\mp 2T_z)Δd_N(x)]/10, where q = u, d and $T_z$ the charge state of a delta. The result can be used to estimate the leading chiral-logarithmic corrections to the quark distributions in the nucleon.

description: Standard flavors of density-functional theory (DFT) calculations are known to fail in describing anions, due to large self-interaction errors. The problem may be circumvented by using localized basis sets of reduced size, leaving no variational flexibility for the extra electron to delocalize. Alternatively, a recent approach exploiting DFT evaluations of total energies on electronic densities optimized at the Hartree-Fock (HF) level has been reported, showing that the self-interaction-free HF densities are able to lead to an improved description of the additional electron, returning affinities in close agreement with the experiments. Nonetheless, such an approach can fail when the HF densities are too inaccurate. Here, an alternative approach is presented, in which an embedding environment is used to stabilize the anion in a bound configuration. Similarly to the HF case, when computing total energies at the DFT level on these corrected densities, electron affinities in very good agreement with experiments can be recovered. The effect of the environment can be evaluated and removed by an extrapolation of the results to the limit of vanishing embedding. Moreover, the approach can be easily applied to DFT calculations with delocalized basis sets, e.g. plane-waves, for which alternative approaches are either not viable or more computationally demanding. The proposed extrapolation strategy can be thus applied also to extended systems, as often studied in condensed-matter physics and materials science, and we illustrate how the embedding environment can be exploited to determine the energy of an adsorbing anion - here a chloride ion on a metal surface - whose charge configuration would be incorrectly predicted by standard density functionals.

description: The main aim of this research work was to develop and evaluate a drug delivery system with compression coating technology to control drug release at a constant rate. The compression coated tablets (CCTs) consist of the hydrophilic matrix core and the hydrophobic waxy coating. The presence of hydrophobic waxy coating could provide sufficient time for hydration of the core to prevent initial burst release. The mechanism research revealed that erosion was the main way of drug release and the releasing area was constant during the entire release process because the core tablet was located in the cup-shaped coating after one side cover was dropped at the lag time. This made the release behavior exhibit zero-order kinetics (R2>0.99). The coating rupture strength and the core swelling force at the lag time influenced erosion rate thus affecting release rate. Different solubility of drugs (propranolol hydrochloride, melatonin, and nifedipine) was selected as model drugs and the properties of the prepared CCTs in terms of formulations and in vitro release were evaluated. The release rate was independent of solubility, medium pH, and osmotic pressure. This zero-order controlled system could be applied to both controlled drug delivery and chrono pharmaceutical drug delivery.

description: In the wake of increasing difficulties with producing enough food from land areas through the world, attention is being given to the sea as a source of food. Because the sea constitutes a common property resource, factor productivity is heavily influenced by technological externalities. The sea is also subjext to the spectre of Malthusian scarcity since man cannot manipulate the ocean environment (Barnett and More, 1963). We estimated the parameters using ordinary least squares of the dynamic Schaefer production model of the intervention of man into oceanic ecosystem. A second production model for the sea specifying diminishing returns to capital and labor for any fixed biomass was developed. The parameters of the latter model were estiamted by a computer search technique. The results indicate that the industry production function for marine life is subject to diminishing physical returns to capital and labor. For the cases considered in this study it also appears that the parabolic yield function developed by Schaefer, assuming constant returns to factors inputs, is not as realistic as a production function with diminishing returns to inputs with a given biomass.

description: The main problem faced by smart contract platforms is the amount of time and computational power required to reach consensus. In a classical blockchain model, each operation is in fact performed by each node, both to update the status and to validate the results of the calculations performed by others. In this short survey we sketch some state-of-the-art approaches to obtain an efficient and scalable computation of smart contracts. Particular emphasis is given to sharding, a promising method that allows parallelization and therefore a more efficient management of the computational resources of the network.

description: We consider the geometrical formulation in central charge superspace of the N=4 supergravity containing an antisymmetric tensor gauge field. The theory is on-shell, so clearly, the constraints used for the identification of the multiplet together with the superspace Bianchi identities imply equations of motion for the component fields. We deduce these equations of motion in terms of supercovariant quantities and then, we give them in terms of component fields. These equations of motion, deduced from the geometry, without supposing the existence of a Lagrangian, are found to be the same as those derived from the Lagrangian given in the component formulation of this N=4 supergravity multiplet by Nicolai and Townsend.

description: Surface-ocean changes in the North Atlantic are closely linked to modes of atmospheric variability, the most dominant of which is the North Atlantic Oscillation. The aims of this study were to investigate high-frequency climate variability in the North Atlantic through the use of high-resolution fossil marine diatom records sparming the last 2000 years. Core sites in the Muros Ria, in northwest Spain, and on the western Norwegian Margin were selected for their high sedimentation rates and their proximity to the NA O pressure centres. The diatom record's high resolution permitted comparison to nearby instrumental time series where significant relationships were found with precipitation, the NAO Index and extended NA O Index reconstructions.

description: Van der Waals heterostructures give access to a wide variety of new phenomena that emerge thanks to the combination of properties brought in by the constituent layered materials. We show here that owing to an enhanced interaction cross section with electrons in a type I van der Waals heterostructure, made of single layer molybdenum disulphide and thin boron nitride films, electrons and holes created in boron nitride can be transferred to the dichalcogenide where they form electron-hole pairs yielding luminescence. This cathodoluminescence can be mapped with a spatial resolution far exceeding what can be achieved in a typical photoluminescence experiment, and is highly valuable to understand the optoelectronic properties at the nanometer scale. We find that in heterostructures prepared following the mainstream dry transfer technique, cathodoluminescence is locally extinguished, and we show that this extinction is associated with the formation of defects, that are detected in Raman spectroscopy and photoluminescence. We establish that to avoid defect formation induced by low-energy electron beams and to ensure efficient transfer of electrons and holes at the interface between the layers, flat and uniform interlayer interfaces are needed, that are free of trapped species, airborne ones or contaminants associated with sample preparation. We show that heterostructure fabrication using a pick-up technique leads to superior, intimate interlayer contacts associated with significantly more homogeneous cathodoluminescence.

description: The Egyptian farmers, as small producers of limited resources in most cases, are expected to go on devoting most of their lands to production of traditional staple foods. Nevertheless, specifying the entire production of grain to human, rather than animal consumption and adoption of high grain yield varieties on expense of straw has become economically inefficient as relatively less profitable. The remedy for this calls for bidding up administrative prices of grain, and increasing low cost supplies of animal feeds.
Hidden Markov and state space models: asymptotic analysis of exact and approximate methods for prediction, filtering, smoothing and statistical inference

description: State space models have long played an important role in signal processing. The Gaussian case can be treated algorithmically using the famous Kalman filter. Similarly since the 1970s there has been extensive application of Hidden Markov models in speech recognition with prediction being the most important goal. The basic theoretical work here, in the case $X$ and $Y$ finite (small) providing both algorithms and asymptotic analysis for inference is that of Baum and colleagues. During the last 30-40 years these general models have proved of great value in applications ranging from genomics to finance. Unless the $X,Y$ are jointly Gaussian or $X$ is finite and small the problem of calculating the distributions discussed and the likelihood exactly are numerically intractable and if $Y$ is not finite asymptotic analysis becomes much more difficult. Some new developments have been the construction of so-called ``particle filters'' (Monte Carlo type) methods for approximate calculation of these distributions (see Doucet et al. [4]) for instance and general asymptotic methods for analysis of statistical methods in HMM [2] and other authors. We will discuss these methods and results in the light of exponential mixing properties of the conditional (posterior) distribution of $(X_1,X_2,...)$ given $(Y_1,Y_2,...)$ already noted by Baum and Petrie and recent work of the authors Bickel, Ritov and Ryden, Del Moral and Jacod, Douc and Matias.

We calculate this enhancement factor with a modal approach pertaining analytical results in the case of a nanosphere. We calculate the Green's function of the system relaying on the spectral properties of the electrostatic operator, fully known for spherical geometry. In contrast to other treatments, the present calculations are straightforward for any molecular orientation giving modal information about the response of the system. Numerical calculations and further discussions are also provided.

The Neel temperature T_N=3.8(1) K is also the same as the ambient-pressure one, although the curve of order parameter has changed by pressure.

In particular, we employ the well-known MARTINI force field and its modifications to perform extended molecular dynamics simulations at the $μ$s timescale, which take slow relaxation processes of polystyrene into account, such that the simulations permit analyzing the bulk modulus, the shear modulus, and the Poisson ratio. We show that through the iterative modification of MARTINI force field parameters it turns out to be possible to affect the shear modulus and the bulk modulus of the system, making them closer to those values reported in the experiment.

description: Changes in the 2014 Farm Bill have reconnected federally-subsidized crop insurance to conservation compliance and eliminated direct payments that were tied to conservation compliance. The net effects of these changes on producers’ incentives to comply with conservation standards and on the environment are uncertain, especially in regions such as the Mississippi Delta. We propose pilot crop insurance programs to improve the link between federally-subsidized crop insurance and conservation compliance in the southern United States and for crops such as cotton. The objective of this study was to determine Tennessee and North Central Mississippi cotton producers’ willingness to participate in hypothetical pilot programs that would incentivize use of cover cropping and no-till practices coupled with crop insurance via an additional cost share payment above current Environmental Quality Incentive Program cost share payments. Data were collected using a mail survey of Tennessee and North Central Mississippi cotton producers conducted in early 2015. A bivariate probit model was estimated to ascertain the factors that impact cotton producers’ willingness to participate in two pilot programs that link cover cropping or no-till with Stacked Income Protection Plan crop insurance. Results found that 35% of the cotton producers would be willing to participate in the cover cropping and Stacked Income Protection Plan pilot program, while 28% indicated they would participate in the no-till and Stacked Income Protection Plan pilot program. Results from the bivariate probit model showed that producers already planning to use Stacked Income Protection Plan in 2015 were more willing to participate in the pilot programs. A producers’ age, income, and debt-to-asset ratio influenced their willingness to participate in the pilot programs. More producers stated they used no-till production than cover crops; therefore, we made pairwise comparisons between producers’ ratings of potential outcomes from using cover cropping and no-till as well as between users and non-users of each of those practices. The results provide unique insight into producers’ perceptions of these practices. Overall, the proposed hypothetical pilot programs could improve the linkage between federally-subsidized crop insurance and conservation compliance; however, future research should consider the potential for these pilot programs for other crops and regions of the United States.

description: For processes involving structure functions and/or fragmentation functions, arguments that, over a range of a proper kinematic variable, there is a part that dominates the next-to-leading order (NLO) corrections are briefly reviewed. The arguments are tested against more recent NLO and in particular complete next-to-next-to-leading order (NNLO) calculations. A critical examination of when these arguments may not be useful is also presented.

description: Sheep (Ovis aries L.) grazing, a cost-effective method of weed control compared with herbicide application and tillage, may influence soil C fractions by consuming crop residue and weeds and returning C through feces and urine to the soil. We examined the effect of three weed management practices (sheep grazing, herbicide application, and tillage) and two cropping sequences (continuous spring wheat [Triticum aestivum L.] [CSW] and spring wheat-pea [Pisum sativum L.]/barley [Hordeum vulgare L.] mixture hay-fallow [W-P/B-F]) on soil microbial biomass C (MBC), potential C mineralization (PCM), and particulate organic C (POC) in relation to soil organic C (SOC) at the 0- to 30-cm depth from 2009 to 2011 in southwestern Montana. The MBC at 0 to 5 cm was greater with tillage on CSW than tillage on W-P/B-F in 2009 and 2011, but was greater with herbicide application on CSW than tillage on CSW in 2010. The POC at 0 to 5 cm and 15 to 30 cm was greater with sheep grazing than herbicide application on CSW and W-P/B-F, but at 5 to 15 cm was greater with grazing on CSW. The MBC, PCM, and POC at all depths decreased from 2009 to 2011. Crop residue incorporation into the soil increased MBC with tillage on CSW. Lower proportions of labile than nonlabile organic matter through feces and urine probably reduced MBC at the soil surface, but increased POC with sheep grazing compared with herbicide application on CSW and W-P/B-F. Sheep grazing may increase coarse soil organic matter compared with microbial biomass in dryland cropping systems.

description: We seek to achieve the Holy Grail of Bayesian inference for gravitational-wave astronomy: using deep-learning techniques to instantly produce the posterior $p(θ|D)$ for the source parameters $θ$, given the detector data $D$. To do so, we train a deep neural network to take as input a signal + noise data set (drawn from the astrophysical source-parameter prior and the sampling distribution of detector noise), and to output a parametrized approximation of the corresponding posterior. We rely on a compact representation of the data based on reduced-order modeling, which we generate efficiently using a separate neural-network waveform interpolant [A. J. K. Chua, C. R. Galley & M. Vallisneri, Phys. Rev. Lett. 122, 211101 (2019)]. Our scheme has broad relevance to gravitational-wave applications such as low-latency parameter estimation and characterizing the science returns of future experiments.

description: This study was designed to analyze drivers of dry common beans trade in Lusaka, Zambia. Specifically, the study analyzed the effect of common bean grain characteristics on bean market price. Data was collected using structured questionnaires from 225 traders stationed in three markets namely: Soweto, Chilenje and Mtendere. Using hedonic pricing, the findings reveal that medium sized grain was an important characteristic which significantly affected the pricing of common bean. For instance, it was observed that medium grain size fetched ZMW1.266 per kilogram (kg) and ZMW 1.042 per kg more than grains of smaller size in the pooled and Soweto market sample, respectively. It was further revealed that yellow, yellow and white color significantly affected the bean price received by traders. Other factors which significantly affected the pricing of beans included age of the trader, being a retail trader and trading at Chilenje market. Given these findings, common bean breeders need to include traders and consumers as important actors whose knowledge can make resourceful impact in varietal development. Furthermore, interventions by policy makers that respond to the social economic needs of traders is recommended to improve bean trade.

description: The utilisation of improved seeds is reliant on distribution system and farmers’ preferences in using the seed. Primary data were collected from key informant interviews in seed delivery chains and a farmer survey to analyse the northern Ghanaian seed delivery systems and factors influencing the adoption of improved seed by farmers. The seed system in Ghana is made up of three main components; a formal seed system, an informal farmers’ seed system and a quasi-formal seed system. The seed chain starts with breeder seed production by Council for Scientific and Industrial Research (except for imported seed) and ends with the grain farmer as the final consumer. The communication flows between members, strength of relationships and farm characteristics reveled to be affecting the improved seed uptake by smallholders in Northern Ghana. The study highlights the value of strengthening the seed delivery system and improving the availability and accessibility of improved seed varieties.
Statistical equivalence and stochastic process limit theorems
Creators: name: Brown, Lawrence D.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Statistics Theory (math.ST)
subject: FOS: Mathematics

description: A classical limit theorem of stochastic process theory concerns the sample cumulative distribution function (CDF) from independent random variables. If the variables are uniformly distributed then these centered CDFs converge in a suitable sense to the sample paths of a Brownian Bridge. The so-called Hungarian construction of Komlos, Major and Tusnady provides a strong form of this result. In this construction the CDFs and the Brownian Bridge sample paths are coupled through an appropriate representation of each on the same measurable space, and the convergence is uniform at a suitable rate. Within the last decade several asymptotic statistical-equivalence theorems for nonparametric problems have been proven, beginning with Brown and Low (1996) and Nussbaum (1996). The approach here to statistical-equivalence is firmly rooted within the asymptotic statistical theory created by L. Le Cam but in some respects goes beyond earlier results. This talk demonstrates the analogy between these results and those from the coupling method for proving stochastic process limit theorems. These two classes of theorems possess a strong inter-relationship, and technical methods from each domain can profitably be employed in the other. Results in a recent paper by Carter, Low, Zhang and myself will be described from this perspective.

description: Normally one thinks of the observed cosmological constant as being so small that it can be utterly neglected on typical astrophysical scales, only affecting extremely large-scale cosmology at Gigaparsec scales. Indeed, in those situations where the cosmological constant only has a quantitative influence on the physics, a separation of scales argument guarantees the effect is indeed negligible. The exception to this argument arises when the presence of a cosmological constant qualitatively changes the physics. One example of this phenomenon is the existence of outermost stable circular orbits (OSCOs) in the presence of a positive cosmological constant. Remarkably the size of these OSCOs are of a magnitude to be astrophysically interesting. For instance: for galactic masses the OSCOs are of order the inter-galactic spacing, for galaxy cluster masses the OSCOs are of order the size of the cluster.
