Exploring Fifth Force Interactions with 18th Century Technology
Creators: name: Steffen, J. H.
Publisher: name: arXiv
Year: 2005
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Many theories which unify gravity with the other known forces of nature predict the existence of an intermediate-range ``fifth force'' similar to gravity. Such a force could be manifest as a deviation from the gravitational inverse-square law. Currently, at distances near $10^{-1}$m, the inverse-square law is known to be correct to about one part per thousand. I present the design of an experiment that will improve this limit by two orders of magnitude. This is accomplished by constructing a torsion pendulum and source mass apparatus that are particularly insensitive to Newtonian gravity and, simultaneously, maximally sensitive to violations of the same.

A Survey of Approximate Quantile Computation on Large-scale Data (Technical Report)

Subjects: subject: Data Structures and Algorithms (cs.DS)

subject: FOS: Computer and information sciences

description: As data volume grows extensively, data profiling helps to extract metadata of large-scale data. However, one kind of metadata, order statistics, is difficult to be computed because they are not mergeable or incremental. Thus, the limitation of time and memory space does not support their computation on large-scale data. In this paper, we focus on an order statistic, quantiles, and present a comprehensive analysis of studies on approximate quantile computation. Both deterministic algorithms and randomized algorithms that compute approximate quantiles over streaming models or distributed models are covered. Then, multiple techniques for improving the efficiency and performance of approximate quantile algorithms in various scenarios, such as skewed data and high-speed data streams, are presented. Finally, we conclude with coverage of existing packages in different languages and with a brief discussion of the future direction in this area.

description: This study was created at Carbó, Sonora, México, during 2006 to determine calf production strategies evaluating: 1) Early weaning (EW), 2) Creep feeding (CF) and 3) Control (C), and to analyze benefice-cost and their profitability. Sixty animals were randomly selected from a 5 year old Charbray cow group that calved among the 15 and 20 of June 2006. For each treatment, 20 animals were grouped, 10 males and 10 females. Evaluated variables were: (1) Calf birth weight, (2) Cow weight and body condition at calving, (3) calf weight at calving, (4) Calf selling weight; (5) Weight and cow condition at calving, (7) Calf production costs and (8) Profitability projection with the three sceneries indicated. Evaluated variables were analyzed by ANOVA (P<0.05). Some financial runs were made on a computer with software for analysis and evaluation of beef inversion projects. Average calf daily gains were 1.32, 1.13 and 0.43 kg/animal/day for EW, CF and the control, treatments, respectively. Cow pregnancy percentage was 95, 85 and 75 and the number of open days was 90, 165 y 240, for treatments EW, CF and (C), respectively. Control treatment yielded negative profits during the 10 projected years. In CF, although gains were low during the first two years, these varied from $54,486 to $69,453 from year there to tenth. With EW the best results were obtained with annual gains starting at the third year and varied from $108,571 a $119,782. Both EW as well as CF shows a viable alternative to increase ranch productivity and ratability. Results from the financial analyses show that the greatest benefit was obtained with EW because it allows for calf production in a continuous way during the 10 years of the project as compared to (CF) and (C); which show out of phase in the production cycles originated by the large number of open days between calving, low pregnancy percentages, and high production costs.

description: An efficient joint source-channel (s/c) decoder based on the side information of the source and on the MN-Gallager algorithm over Galois fields is presented. The dynamical block priors (DBP) are derived either from a statistical mechanical approach via calculation of the entropy for the correlated sequences, or from the Markovian transition matrix. The Markovian joint s/c decoder has many advantages over the statistical mechanical approach. In particular, there is no need for the construction and the diagonalization of a qXq matrix and for a solution to saddle point equations in q dimensions. Using parametric estimation, an efficient joint s/c decoder with the lack of side information is discussed. Besides the variant joint s/c decoders presented, we also show that the available sets of autocorrelations consist of a convex volume, and its structure can be found using the Simplex algorithm.

description: The present research was made in the producer's organization named Fishing and Aquaculture production of goods and aquaculture services of the High Rivera S.C. of R.L. in Palizada, Campeche, Mexico; This research aimed to determine the profitability of the investment project of mojarra castarrica to prove whether the invested resources have been able to increase earnings to the Cooperative Society members. Based on the above, the profitability indicators were calculated as established in the methodology for the formulation and evaluation of investment projects in order to measure the profitability of the producers' organization; such indicators were: Net Present Value (NPV), Benefit-Cost Relationship (B/C), Benefit-Net Investment Relationship (N/K) and, the Internal Rate of Return (IRR). The results obtained in a ten year analysis period are: NPV = 563,743; B/C = 1.34 and the IRR = 141.6%. When the sensibility analysis was done to the income structure and total costs, it was observed that the project can suffer a revenue decrease of 20 percent, but the project will still be profitable. On the other side, the total costs may experience an increase of 20 percent and the project will continue giving utilities to the members of the economic organization.

description: During the first half of 2008, a researching study was done through interviews for some purchase department employees of selected supermarkets, as well as the people that acquire mushrooms “Pleurotus Ostreatus” and other edible mushrooms in Mérida, Yucatán. This study was done with the purpose of identifying their consumer behavior, consumption and to understand how the product is perceived in the supermarket shopping area. The collected data was processed using the percentages technique. It found that the majority (75 %) of respondents had mid-higher and higher education, also 50% were from Yucatan and the remaining percentage from other states in Mexico. The market segment consists mainly of women (65%), in relation to men (35%). The main reasons for purchasing include statements of the nutritional value of the product and family traditions. Most consumers of mushrooms (Pleurotus Ostreatus) considered that it has a high price, but also good quality. Finally, the majority (75 %) stated that they are willing to consume other varieties of mushrooms as well as processed. The study provides relevant information for mushrooms producers for their decision-making process, based on the characteristics and real needs of the product consumers.

description: We calculate the counting statistics of electron transfer through an open quantum dot with charging interaction. A dot that is connected to leads by two single-channel quantum point contacts in an in-plane magnetic field is described by a Luttinger liquid with impurity at the Toulouse point. We find that the fluctuations of the current through this conductor exhibit distinctive interaction effects. Fluctuations saturate at high voltages, while the mean current increases linearly with the bias voltage. All cumulants higher than the second one reach at large bias a temperature independent limit.

description: Beekeeping is an activity of great socioeconomic importance in Mexico, since 80% of beekeepers are resource-poor farmers; it is among the top three of the livestock subsector and is a source of foreign exchange activity, over the 80% of the production from 59.00 tons approximately, is exported. Mexican Honey is widely known for its high quality, however, due to improper use of certain medications such as antibiotics and sulfa drugs, used to control bee diseases, may become contaminated resulting in quality problems that limit international marketing, leading to the rejection of shipments of honey. International quality standards are becoming more demanding with regard to the residual concentration of these compounds in high-quality honey. The aim of this study is to evaluate the effect of time and storage temperature on the degradation of antibiotics in honey.

In the decay state classification by Hunter (1990), raw wood is defined as fresh wood with a short time since death, hence wood densities of living trees are used for fresh wood. Dead wood data were collected during the summer of 2009 on 21 Picea abies-dominated sites and 19 Fagus sylvatica dominated sites across Switzerland. To obtain wood densities, samples were dried at 105–110 °C, and for C content – at 65 °C (Dobbertin and Jüngling 2009).

description: We present an extension of reverse engineered Kohn-Sham potentials from a density matrix renormalization group calculation towards the construction of a density functional theory functional via deep learning. Instead of applying machine learning to the energy functional itself, we apply these techniques to the Kohn-Sham potentials. To this end we develop a scheme to train a neural network to represent the mapping from local densities to Kohn-Sham potentials. Finally, we use the neural network to up-scale the simulation to larger system sizes.

description: Through ultrafast pump-probe spectroscopy with intense pump pulses and a wide continuum probe, we show that interband exciton peaks in single-walled carbon nanotubes (SWNTs) are extremely stable under high laser excitations. Estimates of the initial densities of excitons from the excitation conditions, combined with recent theoretical calculations of exciton Bohr radii for SWNTs, suggest that their positions do not change at all even near the Mott density. In addition, we found that the presence of lowest-subband excitons broadens all absorption peaks, including those in the second-subband range, which provides a consistent explanation for the complex spectral dependence of pump-probe signals reported for SWNTs.

description: We study the solar wind helium-to-hydrogen abundance's ($A_\mathrm{He}$) relationship to solar cycle onset. Using OMNI/Lo data, we show that $A_\mathrm{He}$ increases prior to sunspot number (SSN) minima. We also identify a rapid depletion and recovery in $A_\mathrm{He}$ that occurs directly prior to cycle onset. This $A_\mathrm{He}$ Shutoff happens at approximately the same time across solar wind speeds ($v_\mathrm{sw}$), implying that it is formed by a mechanism distinct from the one that drives $A_\mathrm{He}$'s solar cycle scale variation and $v_\mathrm{sw}$-dependent phase offset with respect to SSN. The time between successive $A_\mathrm{He}$ shutoffs is typically on the order of the corresponding solar cycle length. Using Brightpoint (BP) measurements to provide context, we infer that this shutoff is likely related to the overlap of adjacent solar cycles and the equatorial flux cancelation of the older, extended solar cycle during Solar Minima.

A new set of Monte Carlo moves for lattice random-walk models of biased diffusion

description: We recently demonstrated that standard fixed-time lattice random-walk models cannot be modified to properly represent biased diffusion processes in more than two dimensions. The origin of this fundamental limitation appears to be the fact that traditional Monte Carlo moves do not allow for simultaneous jumps along each spatial direction. We thus propose a new algorithm to transform biased diffusion problems into lattice random walks such that we recover the proper dynamics for any number of spatial dimensions and for arbitrary values of the external field. Using a hypercubic lattice, we redefine the basic Monte Carlo moves, including the transition probabilities and the corresponding time durations, in order to allow for simultaneous jumps along all Cartesian axes. We show that our new algorithm can be used both with computer simulations and with exact numerical methods to obtain the mean velocity and the diffusion coefficient of point-like particles in any dimensions and in the presence of obstacles.
Paving the path to Jihad : explaining the development of political Islam in post-Soviet central Asia
Creators: name: Swanzey, Kimberly R.
Publisher: name: University of British Columbia
Year: 2009

description: Despite its relatively secular nature and traditionally non-challenging relationship with the state, Central Asian Islam has nevertheless produced political manifestations in regional opposition groups today. Why has this happened? Clearly, the reasons behind this development are multifaceted and complex, involving both internal and external pressures, and it would be overly simplistic to assert that any one factor has acted in isolation. This thesis argues that, both directly and indirectly, state responses to Islamism have created a self-perpetuating cycle in which excessive government controls have created an environment of social frustration that is conducive to the rise of unofficial opposition groups, while simultaneously reducing the states' capacity to oppose the movement. In this context, where there are no moderate authority alternatives and little opportunity to achieve change within existing state structures, Islamism has emerged as the main mobilization of opposition forces, providing an alternative system based on the failures of the state and the symbols of a common and persecuted ideology.

description: We propose a nonlinear manifold learning technique based on deep convolutional autoencoders that is appropriate for model order reduction of physical systems in complex geometries. Convolutional neural networks have proven to be highly advantageous for compressing data arising from systems demonstrating a slow-decaying Kolmogorov n-width. However, these networks are restricted to data on structured meshes. Unstructured meshes are often required for performing analyses of real systems with complex geometry. Our custom graph convolution operators based on the available differential operators for a given spatial discretization effectively extend the application space of deep convolutional autoencoders to systems with arbitrarily complex geometry that are typically discretized using unstructured meshes. We propose sets of convolution operators based on the spatial derivative operators for the underlying spatial discretization, making the method particularly well suited to data arising from the solution of partial differential equations. We demonstrate the method using examples from heat transfer and fluid mechanics and show better than an order of magnitude improvement in accuracy over linear methods.

County, Mexico, to identify opportunities and constraints to export melon of Mapimí to the United States market. To gather information on technology, safety and marketing, was designed and implemented a survey of major producers in the Mapimí County, which by their production volumes have greater export potential. In general it was found that private farmers of Mapimí have a good technological level emphasizing the use of hybrid seeds, plastic mulch, drip tape and pollinating bees. In the case of inocuity producers have an idea of the subject of Good Agricultural Practices (GAP) and Good Manufacturing Practices (GMP), but they need more training. In the commercialization it is perceived a need of meetings with potential buyers of the United States to see possible contracts of sale.

description: The present work carried out in 2006 with the objectives of estimating the production costs, and the margins of commercialization of the production fresh prickly pear in the state of Hidalgo. In order to do the work, the methodologies developed by Morris (1990), by Caldentey and De Haro (2004) were used. Altogether 60 surveys, 44 to producers and 16 to dealers of tuna were applied. The results report that in Hidalgo, three types of producers are outstanding; the leader with 9%, the generic with 61 % and the basic with 30%, whose respective production costs of each one were $ 14,532/ha-1, $ 9,626/ha-1 and $ 3,686/ha-1 respectively. The commercialization cost for the production leader was $ 1.17/kg-1, where 40 % was the storage, 26 % was the transport, 24 % was the packing and 10 % was the spine removal. With regard to the costs of commercialization for the generic producer was $ 0.70/kg-1. The highest absolute margin in commercialization was obtained by the production leader, 3.50/kg-1, when commercializing prickly pear in commercial centers with $ 4.63/kg-1, in which $ 1.17/kg-1 correspond to costs and $ 2.33/kg-1 to the profits; also the highest relative margin was obtained at this level and represented 40.6 % of the consumer price. The most important factors that contributed to a better income from the production leader were the productivity and quality of the product.

description: Economists are relying on agronomic concepts to construct weather or climate independent variables and improve the reliability and efficiency of econometric models of climate change impact on U.S. agriculture. The use of cumulative heat measures in agronomy (growing degree-days), has recently served as a basis for the introduction of plurimonthly calendar heat variables in these models. However, season-long weather conditions seem at odds with conventional agronomic wisdom that emphasizes crucial differences in crop stage sensitivity to environmental stress. In this paper I show that weather variables matched to key corn development stages provide an enhanced and more stable fit than their calendar counterparts. More importantly, the proposed season-disaggregated framework yields very different implications for adaptation than its calendar counterparts as it indicates that most of the projected yield damages are accounted during the flowering period, a relatively short period in the crop cycle. This should open the door to more advanced yield models that account for additional possibilities of adaptation and thus provide a more nuanced outlook on the potential impacts of climate change on crop yields.

description: Labels, certifications and endorsements signaling the quality of food have an impact on the purchasing choices of multiple segments of US consumers. At the same time, not much is known about the relationships between the sources providing information through these quality signals and consumer choices. In this paper, we explore 1) whether the credibility of an information source has an impact on US consumers’ beef brand choices; 2) which labels, certifications and endorsements are chosen by US consumers among a range of eight brands with pre-selected sources of information; 3) which consumer segments have different perceptions on information sources and beef brand choices. Data are collected through an on-line survey on a representative sample of 460 US consumers and analyzed through structural equation modeling. The results show that credibility - although it has a positive impact on consumers’ brand choice - is a complex concept which needs to be dissected in more specific variables, namely perceived knowledgeability, perceived absence of vested interests, perceived absence of mistakes in the past and trust. In particular, perceived knowledgeability and perceived absence of vested interests of the information source are inversely proportional.

description: Agribusiness firms are increasingly hiring non-agriculture college graduates. Unclear is whether the demand for non-agriculture graduates is predicated on an undersupply of agriculture graduates or if non-agriculture graduates have skills that are not being developed in traditional agriculture programs. This study uses a large random sample of graduates of a Midwestern Land-Grant University to explore the returns by major in the agricultural and non-agricultural sectors. The strength of the study is its ability to identify the value of agricultural sector-specific skills versus general skills developed by major. The results suggest that there are substantial returns to agriculture majors working in agriculture, but only when the firms are located in urban areas. In addition, the pay gap between working in agriculture and outside of agriculture varies by majors within the College of Agriculture and Life Sciences. This suggests that some majors develop substantial sector-specific skills, while others, notably Agricultural Business/Agricultural Economics develop more generally valued skills.
Four lepton production and the accuracy of QED FSR

description: We scrutinise the ability of the primary QED final-state resummation tools, combined with electroweak virtual corrections, to reproduce the exact next-to-leading order electroweak calculation in the four-charged-lepton final state. We further examine the dependence of the findings on the lepton-photon dressing-cone size as well as the resonance identification strategy. Overall we find excellent agreement with the fixed-order result, but partial differences not directly connected with resummation-induced higher-order effects at the few-percent level are observed in some cases, which are relevant for precision measurements.

description: I study the determinants of ISO 14001 certification in a sample of manufacturing firms in China as well as the effect of ISO 14001 certification on firm environmental performance. Results indicate that ISO 14001 plays an important role in signaling the firm's environmental technology to environmentally conscious customers. ISO 14001 also appears to improve firm environmental performance, even after controlling for endogeneity between performance and certification.

description: We calculate the two-pion wave function in the ground state of the I=2 $S$-wave system and find the interaction range between two pions, which allows us to examine the validity of the necessary condition for the finite-volume method for the scattering length proposed by Lüscher. We work in the quenched approximation employing a renormalization group improved gauge action for gluons and an improved Wilson action for quarks at $1/a=1.207(12) {\rm GeV}$ on $16^3 \times 80$, $20^3 \times 80$ and $24^3 \times 80$ lattices. We conclude that the necessary condition is satisfied within the statistical errors for the lattice sizes $L\ge 24$ ($3.92 {\rm fm}$) when the quark mass is in the range that corresponds to $m_π^2 = 0.273-0.736 {\rm GeV}^2$. We obtain the scattering length with a smaller statistical error from the wave function than from the two-pion time correlator.

description: We examine the affect of retail and manufacturer coupons on the nutritional quality of breakfast cereal purchases made by households. Using household level purchase data we find that coupon usage has a significant impact on the nutritional quality of cereals purchased by households. Specifically, we find that the average sugar content decreases and the fiber content increases. This suggests that coupons have a positive impact on the nutritional quality of cereals purchased by households, holding all other factors constant. Given the prolific use of coupons by households and the fact that they offer both a price discount and an advertisement for products, they might be an effective way to help guide consumers to healthier food choices.

description: Two static yield stress models, one known as YODEL and the newly proposed BreakPro, based on inter-particle bond breaking probability, were employed to comparatively simulate the yield stress of cement suspensions, induced by oscillatory rheological tests with small amplitude oscillatory shear (SAOS). This yield stress occurs at a critical strain in the order of 0.01%, and is commonly attributed to the limit of the linear viscoelastic domain, where attractive forces bridge the cement particles and form a flocculated particle network. YODEL is based on van der Waals (vdW) interaction forces to describe the yield stress for flow onset at a critical strain of a few percent, developed for simple non-reactive particulate suspensions. However, due to the high pH and reactivity of cementitious suspensions, their particle interaction forces are much higher than vdW. Therefore, until now, the YODEL adaptations to cementitious suspensions did not explicitly consider the microstructural-based salient feature of the original model, but used it as an implicit fitting parameter to scale the average attractive force. In this paper, the force is inversely estimated using the full power of the two microstructural-based models, presenting a new mathematical tool for investigating the fragility of the rigid percolated structure of cement suspensions. The model parameters were calibrated on measured yield stresses obtained by SAOS measurements in a high-sensitivity rheometer. The estimated forces were found to be 5.57 (BreakPro) and 1.43 (YODEL) times higher than typical van der Waals forces. The YODEL percolation threshold of 21% turned out to be significantly lower than the one found by the BreakPro model (37%). This indicated that BreakPro modeling assumptions are better suited for the description of yield stress at SAOS critical strain than the YODEL model.
The Virtual Bus: A Network Architecture Designed to Support Modular-Redundant Distributed Periodic Real-Time Control Systems
Creators: name: Turner, Mark
Publisher: name: The Australian National University
Year: 2022

description: The Virtual Bus network architecture uses physical layer switching and a combination of space- and time-division multiplexing to link segments of a partial mesh network together on schedule to temporarily form contention-free multi-hop, multi-drop simplex signalling paths, or 'virtual buses'. Network resources are scheduled and routed by a dynamic distributed resource allocation mechanism with self-forming and self-healing characteristics. Multiple virtual buses can coexist simultaneously in a single network, as the resources allocated to each bus are orthogonal in either space or time. The Virtual Bus architecture achieves deterministic delivery times for time-sensitive traffic over multi-hop partial mesh networks by employing true line-speed switching; delays of around 15ns at each switching point are demonstrated experimentally, and further reductions in switching delays are shown to be achievable. Virtual buses are inherently multicast, with delivery skew across multiple destinations proportional to the difference in equivalent physical length to each destination. The Virtual Bus architecture is not a purely theoretical concept; a small research platform has been constructed for development, testing and demonstration purposes.
