description: We review what has been learnt and what remains unknown about the physics of hot enhancons following studies in supergravity. We recall a rather general family of static, spherically symmetric, non-extremal enhancon solutions describing D4 branes wrapped on K3 and discuss physical aspects of the solutions. We embed these solutions in the six dimensional supergravity describing Type IIA strings on K3 and generalize them to have arbitrary charge vector. This allows us to demonstrate the equivalence with a known family of hot fractional D0 brane solutions, to widen the class of solutions of this second type and to carry much of the discussion across from the D4 brane analysis. In particular we argue for the existence of a horizon branch for these branes.

description: The PHENIX experiment at RHIC has measured transverse energy and charged particle multiplicity at mid-rapidity in Au + Au collisions at $\sqrt{s_{NN}}$ = 19.6, 130, 62.4 and 200 GeV as a function of centrality. The presented results are compared to measurements from other RHIC experiments, and experiments at lower energies. The $\sqrt{s_{NN}}$ dependence of $dE_{T}/dη$ and $dN_{ch}/dη$ per pair of participants is consistent with logarithmic scaling for the most central events. The centrality dependence of $dE_{T}/dη$ and $dN_{ch}/dη$ is similar at all measured incident energies. At RHIC energies the ratio of transverse energy per charged particle was found independent of centrality and growing slowly with $\sqrt{s_{NN}}$. A survey of comparisons between the data and available theoretical models is also presented.

description: This paper deals with the exponential input-to-state stabilization with respect to boundary disturbances of a class of diagonal infinite-dimensional systems via delay boundary control. The considered input delays are uncertain and time-varying. The proposed control strategy consists of a constant-delay predictor feedback controller designed on a truncated finite-dimensional model capturing the unstable modes of the original infinite-dimensional system. We show that the resulting closed-loop system is exponentially input-to-state stable with fading memory of both additive boundary input perturbations and disturbances in the computation of the predictor feedback.

description: The ellipticities and alignments of clusters of galaxies, and their evolution with redshift, are examined in the context of a Lambda-dominated cold dark matter cosmology. We use a large-scale, high-resolution N-body simulation to model the matter distribution in a light cone containing ~10^6 clusters out to redshifts of z=3. Cluster ellipticities are determined as a function of mass, radius, and redshift, both in 3D and in projection. We find strong cluster ellipticities: the mean ellipticity increases with redshift from 0.3 at z=0 to 0.5 at z=3, for both 3D and 2D ellipticities; the evolution is well-fit by e=0.33+0.05z. The ellipticities increase with cluster mass and with cluster radius; the main cluster body is more elliptical than the cluster cores, but the increase of ellipticities with redshift is preserved. Using the fitted cluster ellipsoids, we determine the alignment of clusters as a function of their separation. We find strong alignment of clusters for separations <100 Mpc/h; the alignment increases with decreasing separation and with increasing redshift. The evolution of clusters from highly aligned and elongated systems at early times to lower alignment and elongation at present reflects the hierarchical and filamentary nature of structure formation. These measures of cluster ellipticity and alignment will provide a new test of the current cosmological model when compared with upcoming cluster surveys.

description: The following bibliography is intended to assist people interested in studying the economics of world grain trade. The intended audience is professional economists and students with a research interest. The bibliography includes material on analytical techniques, history, and institutions related to grain trade. A separate list of data sources follows the main entries. The subject is limited to economic aspects of grain rather than to technical agriculture. Coverage is more extensive for wheat than for other grains. The list emphasizes international trade in grain, although for some countries domestic agriculture and trade are inseparable. Interdependence between the domestic and foreign sectors is particularly prominent in the area of trade policy.

description: This report presents the optimal control approach to dynamic optimization. The presentation begins with a simple two-period problem and a level of analysis that should be familiar to anyone who has had an intermediate level course in price theory. The form of this problem is changed slightly to lead smoothly to the development of the Maximum Principle of optimal control for many discrete time periods. This discrete time example is presented in a way that shows clearly the meaning of the Maximum Prinicple in continuous time. An example closely related to the examples given for optimization in discrete time is used to introduce the fundamentals of optimal control in continuous time and the use of phase diagrams for describing important characteristics of the solution. Appendixes provide a unified treatment of constrained optimization, nonlinear programming, and generalize the statement of the Optimal Control problem from the particular examples presented in the body of the report.

description: Open clusters potentially provide an ideal environment for the search for transiting extrasolar planets since they feature a relatively large number of stars of the same known age and metallicity at the same distance. With this motivation, over a dozen open clusters are now being monitored by four different groups. We review the motivations and challenges for open cluster transit surveys for short-period giant planets. Our photometric monitoring survey (EXPLORE/OC) of Galactic southern open clusters was designed with the goals of maximizing the chance of finding and characterizing planets, and of providing for a statistically valuable astrophysical result in the case of no detections. We use the EXPLORE/OC data from two open clusters NGC 2660 and NGC 6208 to illustrate some of the largely unrecognized issues facing open cluster surveys including severe contamination by Galactic field stars ($>$ 80%) and relatively low number of cluster members for which high precision photometry can be obtained. We discuss how a careful selection of open cluster targets under a wide range of criteria such as cluster richness, observability, distance, and age can meet the challenges, maximizing chances to detect planet transits. In addition, we present the EXPLORE/OC observing strategy to optimize planet detection which includes high-cadence observing and continuously observing individual clusters rather than alternating between targets.

description: Milk regulation in North Carolina is extensively analyzed, including regulations affecting producer prices, classification of milk, base provisions, and interplant and interstate milk movements. Also reviewed are regulations affecting processor and retailer prices, the rationale for milk regulation, and some aspects of federal market ing orders. In addition, there is a legal analysis of the leading constitutional court challenges to state milk commissions in the Southeast. In several instances state milk commissions have had their regulations declared unconstitutional because of the Interstate Commerce Clause in the U.S. Constitution.

description: We discuss a sum rule satisfied by the correlation function of two particles with small relative momenta. The sum rule, which results from the completeness condition of the quantum states of the two particles, is first derived and then we check how it works in practice. The sum rule is shown to be trivially satisfied by free particle pair, and then there are considered three different systems of interacting particles. We discuss a pair of neutron and proton in the s-wave approximation and the case of the so-called hard spheres with the phase shifts taken into account up to l=4. Finally, the Coulomb system of two charged particles is analyzed.

Solid-state NMR, X-ray diffraction and neutron diffraction studies on organic guest/zeolite ZSM-5 complexes
Creators: name: Lee, Jang Seob
Publisher: name: University of British Columbia
Year: 2011

description: Zeolites are microcrystalline aluminosilicate materials that have intricate channel systems, into which molecules can be adsorbed. Important as industrial materials, they are used in gas separations, sorption and catalysis where the property of 'molecular sieving' is exhibited toward guest species. Thus, understanding the interactions between guest species and the host zeolite frameworks is central to predicting the syntheses and applications of zeolites, and this requires detailed structural information about the guest/zeolite complexes. For most zeolites, structure determination by single crystal XRD is precluded due to the microcrystalline nature of the materials. As an exception, ZSM-5, which was used exclusively for this thesis, is available in large crystals (> 100 μm). In the quest for a universal method to probe the structures of various types of guest/zeolite complexes, we have developed an alternative approach using solid-state NMR, which is not limited by crystal size, unlike single crystal XRD. The main focus of this thesis is exploring the potential of the NMR method by using it to determine various guest/zeolite complexes followed by verification by diffraction techniques where possible. The NMR method uses the dipolar coupling interactions between nuclei on the organic guest molecules and the silicon nuclei in the zeolite framework, which contain information regarding relative proximities of the protons in the guest to the silicon atoms in the rigid framework. The complexes tested were: o-xylene/ZSM-5, p-dicyanobenzene/ZSM-5, p -dinitrobenzene/ZSM-5 and benzene/ p -xylene/ZSM-5 (the mixture of the two organics as guest molecules in the structure determination of the complex for the first time). Precise structures for all the complexes listed have been determined successfully by the NMR method. Other relevant NMR studies, including connectivity, dynamics and spin diffusion, are also presented to support a better understanding of the interactions between the organic guests and the zeolite frameworks. Verification of the first three complex structures determined by NMR has been done successfully by diffraction methods. For o-xylene/ZSM-5, attempts to apply single crystal XRD were unsuccessful due to the very low diffusivity of the organic. Instead, powder neutron diffraction was used.

The time development of our system is obtained using Wigner distribution functions. In contrast to our discussion for a two-Gaussian wave packet [Phys. Lett. A 286 (2001) 87], we find that, in the absence of dissipation, the interference term does not decay rapidly in time, but in common with the other two terms, it oscillates in time and persists for all times

description: The concepts of operator size and computational complexity play important roles in the study of quantum chaos and holographic duality because they help characterize the structure of time-evolving Heisenberg operators. It is particularly important to understand how these microscopically defined measures of complexity are related to notions of complexity defined in terms of a dual holographic geometry, such as complexity-volume (CV) duality. Here we study partially entangled thermal states in the Sachdev-Ye-Kitaev (SYK) model and their dual description in terms of operators inserted in the interior of a black hole in Jackiw-Teitelboim (JT) gravity. We compare a microscopic definition of complexity in the SYK model known as K-complexity to calculations using CV duality in JT gravity and find that both quantities show an exponential-to-linear growth behavior. We also calculate the growth of operator size under time evolution and find connections between size and complexity. While the notion of operator size saturates at the scrambling time, our study suggests that complexity, which is well defined in both quantum systems and gravity theories, can serve as a useful measure of operator evolution at both early and late times.

description: Supplementary signs are essential to improve riders’ understanding of road signs. In order to attract the rider’s attention and ensure the information on the supplementary sign is effectively delivered, a study on the effective ways to display the information in the supplementary sign is needed. The current study examined the effects of capitalization and information length in supplementary signs on road sign comprehension among riders. A randomized 2 (capitalization: all letters capitalized vs the first letter capitalized) × 2 (information length: long vs. short) factorial design experiment was conducted on 131 young motorcyclists in the Jakarta area. Road sign comprehension was measured using sign comprehension time and sign comprehension level. A 2 × 2 factorial ANOVA analysis showed a significant effect of information length on sign comprehension time: less information in supplementary signs can increase sign comprehension time. Additionally, a significant interaction was found between capitalization and information length on sign comprehension level: sign comprehension levels would be improved if supplementary signs were presented with capitalization at the beginning of each word and had a long information length. This study suggests that there is a need to consider the capitalization and length of information in designing supplementary traffic signs. The effective design of supplementary signs could help riders to comprehend the road sign quickly and accurately, thus improving traffic safety.

description: The internet has brought about great change in the astronomical community, but this interconnectivity is just starting to be exploited for use in instrumentation. Utilizing the internet for communicating between distributed astronomical systems is still in its infancy, but it already shows great potential. Here we present an example of a distributed network of telescopes that performs more efficiently in synchronous operation than as individual instruments. RAPid Telescopes for Optical Response (RAPTOR) is a system of telescopes at LANL that has intelligent intercommunication, combined with wide-field optics, temporal monitoring software, and deep-field follow-up capability all working in closed-loop real-time operation. The Telescope ALert Operations Network (TALON) is a network server that allows intercommunication of alert triggers from external and internal resources and controls the distribution of these to each of the telescopes on the network. TALON is designed to grow, allowing any number of telescopes to be linked together and communicate. Coupled with an intelligent alert client at each telescope, it can analyze and respond to each distributed TALON alert based on the telescopes needs and schedule.

description: The paper is concerned with the effect of an exchange rate variation on agricultural trade. Most related literature has dealt with specification of economic models and empirical estimation of model parameters. In contrast, this paper concentrates on the appropriate measurement of multilateral exchange rate changes for the analysis of agricultural trade. Literature on the economic theory of index numbers was reviewed for guidance in constructing effective exchange rate indices. Major existing exchange rate indices were compared including those of the Federal Reserve Board, International Monetary Fund, Morgan Guaranty Trust, and the U.S. Department of Agriculture. New indices were constructed based on" alternative weighting schemes and index forms. In general, measurement differences among indices were not negligible and for certain periods, discrepancies were substantial. Of all the indices considered, the USDA's real trade-weighted dollar showed less appreciation of the dollar since 1980 than any of the other indices based on total trade or. agricultural trade. This raises the question of whether the USDA index understates the importance of exchange rates when large changes occur. The significance of the results is illustrated in terms of an agricultural trade model. It appears that proper measurement of the exchange rate variable may be as important as accurate measurement of parameters of the model.

Point-of-collection testing (POCT) of oral fluid collected from the participants (n = 249) was done using the Evidence MultiSTAT DOA Oral Fluid II Assay kits and the Evidence MultiSTAT analyzer. Out of the total samples, 53 (21.29%) were positive for one or more DOA. A high prevalence of tetrahydrocannabinol (THC) (10.04%) and synthetic cannabinoids were detected in the samples. The use of ketamine, alpha-PVP, LSD, methamphetamine, opiate, 6-MAM, benzodiazepines I, methadone, PCP, tramadol, and amphetamine was also detected and their frequency of use ranged between 4.02 and 0.80%. An association between drug abuse and distance of travel was found in drivers in this study, χ2 (5, N = 249) = 123.5, p < 0.001. Confirmatory analysis using ultra-high performance liquid chromatography-tandem mass spectrometry showed excellent agreement with the results of the screening test. This was the first study conducted among drivers in India for the detection of DOA. Tetrahydrocannabinol (THC) was used more by the goods carriage drivers associated with Kerala State, India. The use of psychoactive substances significantly increased with the distance of travel. Point-of-collection testing (POCT) by the biochip array technology is an efficient method for the detection of these substances.

description: The stated purpose of federal regulation of milk markets is to provide for "orderly" marketing, but very little work has been done on analysis of the social welfare consequences of price or income stabilization in the dairy industry. This omission is surprising, since unpredictable price variability often is listed as a major source of instability in milk markets before federal regulation, and stable, predictable prices are often discussed as a major benefit of regulation. This bibliography discusses studies that analyze the social welfare consequences of price stabilization with risk-neutral consumers and producers, as well as those with risk-averse producers. Also discussed are studies that attempt to measure risk aversion.

description: A common method used to measure the returns to fixed factors on dairy farms is a residual approach in which all but one of the fixed factors,are valued at current market prices and any remaining income is taken as the return to that factor. When using this method it often is found that the returns to the residual factor is negative, which implies that some or all 0f the returns to fixed factors are below current market values. This report presents the findings of experiments with several statistical models that allow simultaneous estimation of the contribution of each factor to variable profit defined as the difference between cash income and cash expenses adjusted for inventory change. The assumptions of each model are described and the mathematical relationships among the models are summarized. Empirical estimates are calculated fora set of dairy farms in North Carolina for the year 1982.

description: This study analyzed the economic tradeoffs between dairying and competing enterprises under selected price and resource conditions in the Central Piedmont of North Carolina. The analysis provided insights into optimal individual producer response to changing economic conditions. Competing enterprises modelled included a beef cow herd, barley, corn, oats, soybeans, wheat, and off-farm employment. A synthetic farm enterprise typical of Central Piedmont resource conditions was constructed using North Carolina Farm Business Management System survey data, North Carolina Agricultural Extension Service budgets, and publications of the Department of Economics and Business at North Carolina State University. Linear programming procedures then analyzed this initial on-farm resource situation to determine the optimal combination of enterprises. The initial optimal enterprise mix was a specialized dairy operation with residual acreage devoted to wheat production. Various optimal enterprise combinations and shadow prices for selected limiting resources were calculated for alternative resource situations. Available labor was much more important than land availability in explaining overall farm profitability. The sensitivity of the initial optimum solution was examined using price-mapping techniques. This initial mix of enterprises was very stable, with dairy production dominating the other enterprises over a wide range of milk and beef prices. Blend milk prices, net of hauling and marketing charges, had to drop more than $3 per hundredweight from $13.68 before the size of the dairy enterprise was significantly reduced from its initial level. Beef entered the optimal farm plan only under a combination of low milk prices and high· beef prices. A combination of historically low milk prices and average-to-high beef prices made off-farm employment profitable. The production of wheat, the only cash crop to be grown, was most extensive when both beef and milk price levels were low.

description: We propose entropic order parameters that capture the physics of generalized symmetries and phases in QFT's. We do it through an analysis of simple properties (additivity and Haag duality) of the net of operator algebras attached to space-time regions. We observe that different types of symmetries are associated with the breaking of these properties in regions of different non-trivial topologies. When such topologies are connected, we show that the non locally generated operators generate an Abelian symmetry group, and their commutation relations are fixed. The existence of order parameters with area law, like the Wilson loop for the confinement phase, or the 't Hooft loop for the dual Higgs phase, is shown to imply the existence of more than one possible choice of algebras for the same underlying theory. A natural entropic order parameter arises by this non-uniqueness. We display aspects of the phases of theories with generalized symmetries in terms of these entropic order parameters. In particular, the connection between constant and area laws for dual order and disorder parameters is transparent in this approach, new constraints arising from conformal symmetry are revealed, and the algebraic origin of the Dirac quantization condition (and generalizations thereof) is described. A novel tool in this approach is the entropic certainty relation satisfied by dual relative entropies associated with complementary regions, which quantitatively relates the statistics of order and disorder parameters.

description: This paper examines how firms in a supply chain can optimally choose the organizational form that governs their business transactions. Alternative organizational forms are characterized by the allocation of managerial decision rights, by information flows, and by transaction cost levels. We focus on the case where one firm or operating division bases its choice of organizational form on: its own costs and capabilities for information gathering and use, the quality of information provided by its trading partner, noise in information transmission channels, the relative importance of investments in site­specific assets and market information, and institutional factors that affect the costs of making transactions under different organizational forms. The model is used to explain observed patterns of organizational change in the U.S. retail food industry.

description: Aims: Hepatitis C virus (HCV) is a slowly progressive disease, often transmitted among people who inject drugs (PWID). Mortality in PWID is high, with an overrepresentation of drug-related causes. This study investigated the risk of death in patients with chronic hepatitis C virus (HCV) infection with or without illicit substance use disorder (ISUD). Methods: Patients with HCV were identified using the Swedish National Patient Registry according to the International Classification of Diseases-10 (ICD-10) code B18.2, with ≤5 matched comparators from the general population. Patients with ≥2 physician visits with ICD-10 codes F11, F12, F14, F15, F16, or F19 were considered to have ISUD. The underlying cause of death was analyzed for alcoholic liver disease, non-alcoholic liver disease, liver cancer, drug-related and external causes, non-liver cancers, or other causes. Mortality risks were assessed using the standardized mortality ratio (SMR) with 95% CIs and Cox regression analyses for cause-specific hazard ratios. Results: In total, 38,186 patients with HCV were included, with 31% meeting the ISUD definition. Non-alcoholic liver disease SMRs in patients with and without ISUD were 123.2 (95% CI, 103.7–145.2) and 69.4 (95% CI, 63.8–75.3), respectively. The significant independent factors associated with non-alcoholic liver disease mortality were older age, being unmarried, male sex, and having ISUD. Conclusions: The relative risks for non-alcoholic liver disease mortality were elevated for patients with ISUD. Having ISUD was a significant independent factor for non-alcoholic liver disease. Thus, patients with HCV with ISUD should be given HCV treatment to reduce the risk for liver disease.

description: The rapid development of information technologies and the COVID-19 pandemic have resulted in the proliferation of online food shopping and food delivery motorcyclists. In contrast to the relatively ample literature on factors influencing fatalities and risky riding behaviors of food delivery motorcyclists, little is known about the determinants of non-fatal crashes involving online food delivery riders. The present study examines the prevalence and factors of non-fatal crashes among food delivery riders. The self-reported data of 393 online food delivery riders were collected in Hanoi and Hochiminh city, Vietnam. Binary logit regression was used to investigate the factors associated with non-fatal crashes. The findings showed that more than half of riders (54%) reported being involved in at least one crash in the last 12 months. The most common risky riding behaviors associated with the crashes included using a mobile phone while riding, neglecting turn signals, red-light running, riding when tired/sleepy, and speeding. The riders who were national migrants, married, and worked on planned delivery routes mainly alone were more likely to experience crashes. At the same time, adequate perceived rewards for their work prevent crash involvement. Perceived risk was not a significant predictor of self-reported crashes. Ensuring road safety for delivery riders requires a systemic effort involving multiple stakeholders, and the private sector plays a crucial role in discouraging risky riding behaviors. It is imperative for the government and regulatory bodies to redefine the delivery job to alleviate the strain on riders and provide resources such as rewards. Specifically, riders should be considered employees rather than partners. Furthermore, it is crucial for the police to take a more active role in preventing dangerous behaviors among delivery riders, such as running red lights. At the same time, supporting financial strategies should be implemented for delivery riders, particularly for those who are migrants or married and may face additional challenges.

description: The Efficient Consumer Response (ECR) initiative is an industry-wide, collaborative effort to reengineer the grocery supply chain. While the success of ECR depends on widespread adoption, the details of ECR implementation will almost certainly differ across firms in any segment of the supply chain, across geographic and market divisions within individual firms, and even across product categories within a single firm. This paper reports findings from an exploratory study of ECR adoption in Minnesota grocery stores. Data were collected through a series of forty interviews with store managers. The overall objective was to describe ECR adoption in the retail store segment of the grocery supply chain. Three general conclusions can be drawn from this study. (I) Location in a major metropolitan area facilitates adoption of some components of the ECR initiative. (2) Stores that are part of a chain, especially a large corporate chain, are making faster progress toward implementation of ECR initiatives than are single stores. (3) ECR adoption and superior performance are closely associated.

description: To compare characteristics and restraint use between a population-based and fitting service sample of child restraint users. Characteristics of the two samples were compared using chi-squared tests. Differences in errors in restraint use observed in the two samples were modeled using logistic regression. There were significant differences in child age (p < 0.001), and restraint types (p < 0.001) between the two samples, with more younger children in the fitting service sample. Controlling for differences in restraint type, the odds that adult participants were female were 61% less in the fitting service sample than in the population-based sample (OR 0.39, 95%CI 0.21–0.71). The odds that adult participants perceived a large risk associated with restraint misuse (OR 3.62, 95%CI 1.33–9.84), had a household income in the highest bracket (OR 3.89, 95%CI 1.20–12.62) and were living in areas of highest socioeconomic advantage (OR 2.72, 95%CI 1.22–6.06) were approximately three times higher in the fitting service sample. Overall, more participants had errors in restraint use in the population-based sample (p = 0.021). However, after controlling for restraint type, securing errors were three times more likely (OR 3.34, 95%CI 1.12–10.2), and serious installation errors were almost twice as likely (OR 1.91, 95% CI 1.09–3.39) in the fitting service sample. While less resource intensive, convenience and/or fitting service samples may be less representative than population-based samples. Given the need for efficiency, methods that combine randomized population-based invitations to participate in restraint fitting check day events across geographically representative areas may be useful for ongoing surveillance of child restraint use.

description: The case study concentrates on the on-farm research activities of the Bangladesh Agricultural Research Institute (BARI), the largest unit of the NARS. The On-Farm Research Division (OFRD), created in 1985, has the exclusive mandate for on-farm research in BARI. On-farm research teams are located at 23 stations and substations, from which they direct technicians in 11 farming system research sites and 83 multi-locational testing sites.The OFRD subsumed four distinct older programs: multi-locational testing of the Soil Fertility and Soil Testing Institute (later renamed the On-Farm Trials Division); cropping system research on the IRRI model; varietal testing and verification of the wheat program; and the adaptive research of the T & V Extension Research Program. An important aspect of the Bangladesh case study is its analysis of the consolidation of these different approaches to OFCOR under common management.
