Subjects: subject: Optics (physics.optics)
subject: Accelerator Physics (physics.acc-ph)
subject: FOS: Physical sciences

description: The generation of electron vortex beams and the conversion of these beams into beams without angular momentum by means of astigmatic optical systems, or vice versa, has been pursued in the optical and the electron microscopy community, but also in the accelerator community in the past decades. Despite different conceptual approaches similar results have been achieved. By adapting the Courant-Snyder theory, which was originally developed for the description of optical properties of accelerators, to the description of laser modes it is shown, that identical mode converters have been developed for charged particle and for light beams, and that the Courant-Snyder phase and the Gouy phase are equivalent.

description: The purpose of this Discussion Paper is to evaluate how economic problems and developments in the dairy industries of Mexico, Central America, Argentina, and Brazil will affect the U.S. dairy sector. Mexico, a signatory to the North American Free Trade Agreement, now applies zero tariffs to imports of most U.S. dairy products. Nonfat dry milk (NFDM) is a notable exception; Mexican tariffs on U.S. exports of NFDM will not go to zero until 2008. However, Mexico’s dairy market no longer represents "low hanging fruit" for U.S. dairy exporters. Margins on exports of bulk dairy products to Mexico are razor thin. Nicaragua and other Central American countries are seeking to expand export sales of dry, hard, salty (morolique) cheese to the U.S. Argentina’s economic recession has hampered that country’s ability to be the dairy supplier of South America. Brazil’s dairy industry has weathered the economic recession with limited damage. Brazil appears poised to be a strong competitor in international dairy markets.
Nonparametric item response modeling for identifying differential item functioning in the moderate-to-small-scale testing context
Creators: name: Witarsa, Petronilla Murlita
Publisher: name: University of British Columbia
Year: 2009

description: Differential item functioning (DIF) can occur across age, gender, ethnic, and/or linguistic groups of examinee populations. Therefore, whenever there is more than one group of examinees involved in a test, a possibility of DIF exists. It is important to detect items with DIF with accurate and powerful statistical methods. While finding a proper DIP method is essential, until now most of the available methods have been dominated by applications to large scale testing contexts. Since the early 1990s, Ramsay has developed a nonparametric item response methodology and computer software, TestGraf (Ramsay, 2000). The nonparametric item response theory (IRT) method requires fewer examinees and items than other item response theory methods and was also designed to detect DIF. However, nonparametric IRT's Type I error rate for DIF detection had not been investigated. The present study investigated the Type I error rate of the nonparametric IRT DIF detection method, when applied to moderate-to-small-scale testing context wherein there were 500 or fewer examinees in a group. In addition, the Mantel-Haenszel (MH) DIF detection method was included. A three-parameter logistic item response model was used to generate data for the two population groups. Each population corresponded to a test of 40 items. Item statistics for the first 34 non-DIF items were randomly chosen from the mathematics test of the 1999 TEVISS (Third International Mathematics and Science Study) for grade eight, whereas item statistics for the last six studied items were adopted from the DIF items used in the study of Muniz, Hambleton, and Xing (2001). These six items were the focus of this study.

description: We consider strategic pricing problems in which each firm chooses between a non-cooperative (individual pricing) strategy and a cooperative (price negotiation) strategy. We first analyze a monopoly supply chain involving a supplier and a retailer, and then investigate two competing supply chains each consisting of a supplier and a retailer. We find that an appropriate power allocation between the supplier and the retailer can make the two firms benefit from negotiating the wholesale and retail prices. When the supplier negotiates the wholesale price, the retailer’s cooperative strategy can always induce supply chain coordination in the monopoly setting, whereas the two supply chains in the duopoly setting can be possibly coordinated only when the retailers determine their retail prices individually. In both the monopoly and duopoly settings, the wholesale price negotiation is a necessary part of the communications between supply chain members. When the supply chain competition intensifies, all firms are more likely to determine their prices individually rather than to negotiate their prices.
$\mathcal{L}^2$ localization landscape for highly-excited states

description: The localization landscape gives direct access to the localization of bottom-of-band eigenstates in non-interacting disordered systems. We generalize this approach to eigenstates at arbitrary energies in systems with or without internal degrees of freedom by introducing a modified $\mathcal{L}^2$-landscape, and we demonstrate its accuracy in a variety of archetypal models of Anderson localization in one and two dimensions. This $\mathcal{L}^2$-landscape function can be efficiently computed using hierarchical methods that allow evaluating the diagonal of a well-chosen Green function. We compare our approach to other landscape methods, bringing new insights on their strengths and limitations. Our approach is general and can in principle be applied to both studies of topological Anderson transitions and many-body localization.

description: It is well documented that “unanticipated” information contained in USDA crop reports induces large price reactions in corn and soybean markets. Thus, a natural question that arises from this literature is: To what extent are futures hedges able to remove or reduce increased price risk around report release dates? This paper addresses this question by simulating daily futures returns, daily cash returns and daily hedged returns around report release dates for two storable commodities (corn and soybeans) in two market settings (North Central Illinois and Memphis Tennessee). Various risk measures, including “Value at Risk,” are used to determine hedging effectiveness, and “Analysis of Variance” is used to uncover the underlying factors that contribute to hedging effectiveness.

description: An inverse live-hog model was estimated to analyze whether there has been a recent increase in the magnitude of live-hog, own-quantity demand flexibility. Estimating the impact of processing capacity-utilization rate changes on live-hog prices was a second objective of this research. Results indicate that live hog prices have become more responsive to changes in hog slaughter, slaughter weight, cold storage stocks, and changes in the processing capacity-utilization rate. Finally, model results indicate that the sharp increase in processing capacity-utilization rates, the increase in average dressed weight, and the increase in hog slaughter all had a negative effect on the live-hog prices.

description: This study examines the return on agricultural assets relative to nonfinancial corporate assets in the general economy using aggregate bureau of Economic Analysis data. Our results indicate that the rate of return on nonfarm assets dominates the rate of return on agricultural assets. The average rate of return on nonfarm assets is higher than the average rate of return on farm assets, and the variance of the rate of return on nonfarm assets is lower than the variance of the rate of return on farm assets. Furthermore, the rate of return on agricultural assets only exceeds the rate of return in the nonfarm sector in 1992.
Scalar field perturbations of the Schwarzschild black hole in the Gödel Universe

description: We investigate the scalar field perturbations of the 4+1-dimensional Schwarzschild black hole immersed in a Gödel Universe, described by the Gimon-Hashimoto solution.This may model the influence of the possible rotation of the Universe upon the radiative processes near a black hole. In the regime when the scale parameter $j$ of the Gödel background is small, the oscillation frequency is linearly decreasing with $j$, while the damping time is increasing. The quasinormal modes are damping, implying stability of the Schwarzschild-Gödel space-time against scalar field perturbations. The approximate analytical formula for large multipole numbers is found.

description: We provide an empirical list of the Galactic dispersion measure ($DM_{Gal}$) contribution to the extragalactic fast radio bursts along 72 sightlines. It is independent of any model of the Galaxy, i.e., we do not assume the density of the disk or the halo, spatial extent of the halo, baryonic mass content, or any such external constraints to measure $DM_{Gal}$. We use 21-cm, UV, EUV and X-ray data to account for different phases, and find that $DM_{Gal}$ is dominated by the hot phase probed by X-ray absorption. We improve upon the measurements of N(\oviin) and f$_{OVII}$ compared to previous studies, thus providing a better estimate of the hot phase contribution. The median $DM_{Gal}$=64$^{+20}_{-23}$ cm$^{-3}$ pc, with a 68\% (90\%) confidence interval of 33--172 (23--660) cm$^{-3}$ pc. The $DM_{Gal}$ does not appear to follow any trend with the galactic longitude or latitude, and there is a large scatter around the values predicted by simple disk+spherical halo models. Our measurements provide more complete and accurate estimates of $DM_{Gal}$ independent from the previous studies. We provide a table and a code to retrieve $DM_{Gal}$ for any FRB localized in the sky.

description: An import demand model, augmented with third-country effect variables, is developed to examine the effects of strong U.S. dollar, volatility of the U.S. dollar, and competition among the exporting countries on the shares of U.S. wheat in Asian markets. In the empirical model, the dependent variable is the market shares of U.S. wheat. Explanatory variables include wheat prices of exporting countries, exchange rates between the importing and exporting countries, and volatilities of the exchange rates. Panel estimation results show that the U.S. currency values and volatility, Australian wheat price, and the volatilities of Canadian and Australian currency values have significant effects on U.S. market shares.
Few Shot Learning Framework to Reduce Inter-observer Variability in Medical Images

description: Most computer aided pathology detection systems rely on large volumes of quality annotated data to aid diagnostics and follow up procedures. However, quality assuring large volumes of annotated medical image data can be subjective and expensive. In this work we present a novel standardization framework that implements three few-shot learning (FSL) models that can be iteratively trained by atmost 5 images per 3D stack to generate multiple regional proposals (RPs) per test image. These FSL models include a novel parallel echo state network (ParESN) framework and an augmented U-net model. Additionally, we propose a novel target label selection algorithm (TLSA) that measures relative agreeability between RPs and the manually annotated target labels to detect the "best" quality annotation per image. Using the FSL models, our system achieves 0.28-0.64 Dice coefficient across vendor image stacks for intra-retinal cyst segmentation. Additionally, the TLSA is capable of automatically classifying high quality target labels from their noisy counterparts for 60-97% of the images while ensuring manual supervision on remaining images. Also, the proposed framework with ParESN model minimizes manual annotation checking to 12-28% of the total number of images. The TLSA metrics further provide confidence scores for the automated annotation quality assurance. Thus, the proposed framework is flexible to extensions for quality image annotation curation of other image stacks as well.

We found that packaging and juice content played a significant role in the choices Indiana consumers made when purchasing fresh-cut melon products. Brand was not as important as the other fresh-cut melon attributes. Indiana consumers had a clear dislike for cup-shaped transparent packages compared with tamper-proof, bowl, and squared packages. However, they were willing to pay a premium for packages that have no fruit juices on the bottom.

Year: 2024

description: The term Internet of Things (IoT) refers to a network of physical things that have sensors, software, and other technologies integrated in them that allow them to communicate with other devices and systems over the internet and exchange data. IoT environmental monitoring systems use IoT devices to collect data about the environment, such as temperature, humidity, air quality, and noise levels. This data is then transmitted to a central server, where it can be analyzed and visualized to provide insights into the environmental conditions. Comprehensive data visualization is essential for IoT environmental monitoring systems. It allows users to easily understand and interpret the large amounts of data that are collected by the systemData visualisation technologies can generate charts, graphs, and other visual representations to discover trends, patterns, and guide decision-making for environmental management. Using IoT environmental monitoring systems with rich data visualisation offers benefits such as:Improved environmental awareness: IoT environmental monitoring systems can provide real-time data about the environment, which can help users to become more aware of the environmental conditions around them. This information can be used to make informed decisions about how to reduce their environmental impact and protect their health. Enhanced decision-making: Comprehensive data visualization tools can help users to identify trends and patterns in the environmental data, which can be used to make better decisions about how to manage the environment.

For example, if an IoT environmental monitoring system shows that the air quality in a particular area is declining, the authorities can take steps to improve the air quality, such as by reducing traffic emissions. Increased efficiency: IoT environmental monitoring systems can help to automate environmental monitoring tasks, which can save time and resources.

For example, an IoT environmental monitoring system can be used to automatically monitor the temperature and humidity in a greenhouse, and to take corrective action if the conditions fall outside of the desired range.

description: We employed Vickrey auctions to generate willingness-to-pay (WTP) data for red meat traceability and related product characteristics with comparable experimental auctions in the United States, Canada, the U.K., and Japan. The results show that subjects are willing to pay a nontrivial premium for traceability, but the same subjects show even higher WTP for traceability-provided characteristics like additional meat safety and humane animal treatment guarantees. The implication is that producers might be able to implement traceable meat systems profitably by tailoring the verifiable characteristics of the product to consumer preferences.

description: A gate-defined quantum dot in bilayer graphene is utilized as a sensitive electrometer for probing the charge density of its environment. Under the influence of a perpendicular magnetic field, the charge carrier density of the channel region next to the quantum dot oscillates due to the formation of Landau levels. This is experimentally observed as oscillations in the gate-voltage positions of the Coulomb resonances of the nearby quantum dot. From the frequency of the oscillations, we extract the charge carrier density in the channel and from the amplitude the shift of the quantum dot potential. We compare these experimental results with an electrostatic simulation of the device and find good agreement.

description: The effects of various supply and demand shifts on beef price, quantity, and industry welfare have been widely studied under the assumption of beef quality homogeneity. In this paper, we construct a model of the beef sector that incorporates differences in beef quality. The model is used to analyze the effect of supply and demand shifts on changes in prices and quantities of high-and low-quality beef and changes in revenue accruing to producers of high-and low-quality beef. Model results indicate that supply and demand shocks have the potential to alter the average quality of beef on the market and the price premium charged for high-quality beef, which has important implications for retailers selling quality-differentiated beef and producers selling cattle on a grid.

description: Whereas consumer theory employs several different empirical specifications for estimating indirect utility functions, producer theory has relied on the Translog specification to estimate the indirect production function. In this paper, we apply Lewbel’s more general functional specification and investigate its implications for the estimation of indirect production functions in productivity analysis. An attractive feature of the Lewbel model is that it nests both the Translog and the almost ideal supply system, offering a method to assess the empirical validity of all three specifications. Aggregate U.S. production data are used to examine the performance of the three models in an empirical application.

The estimation of the latter parameter is performed here by employing the recent adaptive observer scheme of Besancon et al., but applied in a nonstandard form in which a time-varying quantity containing the unknown Riccati parameter is estimated first. Results of computer simulations are presented to illustrate the good feasibility of this approach for a case in which the estimation is not easily accomplished by other means

description: We report a study of the suppressed decays $B^- \to [K^+π^-]_D K^-$ and $B^- \to [K^+π^-]_D π^-$, where $[K^+π^-]_D$ indicates that the $K^+π^-$ pair originates from a neutral $D$ meson. These decay modes are sensitive to the Unitarity Triangle angle $ϕ_3$. We use a data sample containing 275 million $B\bar{B}$ pairs recorded at the $Υ(4S)$ resonance with the Belle detector at the KEKB asymmetric $e^+e^-$ storage ring. The signal for $B^- \to [K^+π^-]_D K^-$ is not statistically significant, and we set a limit $r_B < 0.27$ at 90% confidence level, where $r_B$ is the magnitude of the ratio of amplitudes $| A(B^- \to \bar{D}^0K^-) / A(B^- \to D^0K^-) |$. We observe a signal with $6.4σ$ statistical significance in the related mode, $B^- \to [K^+π^-]_D π^-$.

Antimicrobial Efficacy of Basil Leaf-Based Iron Nanoparticles: Concentration-Dependent Inhibition Against Pathogenic Strains
Creators: name: Swarti Lodhi, Vikrant Jain
Publisher: name: Zenodo
Year: 2024

description: This This study investigates the antimicrobial efficacy of basil leaf-based iron nanoparticles at varying concentrations against selected pathogenic strains, including Staphylococcus aureus, Bacillus cereus, Escherichia coli, Salmonella Enteritidis, and Pasteurellamultocida. The inhibitory effects of the nanoparticles were evaluated and compared with the standard antibiotic Lincomycin. Concentration-dependent trends were observed, revealing an increase in inhibition zones with higher nanoparticle concentrations across all tested organisms.The study highlights the potential of basil leaf-based iron nanoparticles as effective antimicrobial agents, with notable trends indicating concentration-dependent enhancement of inhibitory effects. Comparative analysis with Lincomycin suggests comparable or superior antimicrobial activity, particularly at higher nanoparticle concentrations. These findings contribute valuable insights into the antimicrobial properties of plant-based nanoparticles, underscoring their potential as alternative or complementary agents to traditional antibiotics.The observed susceptibility of pathogenic strains to basil leaf-based iron nanoparticles, even at lower concentrations, opens avenues for further research and development of sustainable antimicrobial agents. Optimizing nanoparticle formulations for enhanced efficacy and elucidating underlying mechanisms are important considerations for future investigations. This study lays a foundation for the potential application of basil leaf-based iron nanoparticles in medical and pharmaceutical contexts, offering new perspectives on the development of novel antimicrobial strategies.
Not just for laughs : what prompts therapists to use humour in a counselling session
Creators: name: Schneebeli, Barbara
Publisher: name: University of British Columbia
Year: 2009

description: This study explored how counsellors' experiences with humor affect their counselling practice. The study examined what motivates counsellors to use humour and how using humour can be important to the counselling field. Furthermore, it exemplified ways counsellors can include this dimension within their practice. An autobiographical method was employed. Participants wrote stories about their experiences with the use of humor and how they incorporated it into counselling. Narrative analysis was used to review the data. A follow up interview with each of the participants served the purpose of confirming and validating the findings generated from the autobiographical accounts. This study illuminates the power of humor, inspires counsellors to examine their own sense of humour, and reminds the field of psychology how imperative the inclusion of humour is to the healing process. Recommendations for future research and implications for counselling are provided.

description: We show that complex multiplication on abelian varieties is equivalent to the existence of a constant rational Kähler metric. We give a sufficient condition for a mirror of an abelian variety of CM-type to be of CM-type as well. We also study the relationship between complex multiplication and rationality of a toroidal lattice vertex algebra.

Relation of X-ray activity and rotation in M dwarfs and predicted time-evolution of the X-ray luminosity

description: We present a sample of 14 M dwarf stars observed with XMM-Newton and Chandra, for which we also computed rotational periods from Kepler Two-Wheel (K2) Mission light curves. We compiled X-ray and rotation data from the literature and homogenized all data sets to provide the largest uniform sample of M dwarfs (302 stars) for X-ray activity and rotation studies to date. We then fit the relation between $L_{\rm x} - P_{\rm rot}$ using three different mass bins to separate partially and fully convective stars. We found a steeper slope in the unsaturated regime for fully convective stars and a nonconstant $L_{\rm x}$ level in the saturated regime for all masses. In the $L_{\rm x}/L_{\rm bol}-R_{\rm O}$ space we discovered a remarkable double gap that might be related to a discontinuous period evolution. Then we combined the evolution of $P_{\rm rot}$ predicted by angular momentum evolution models with our new results on the empirical $L_{\rm x} - P_{\rm rot}$ relation to provide an estimate for the age decay of X-ray luminosity. We compare predictions of this relationship with the actual X-ray luminosities of M stars with known ages from 100 Myr to a few billion years. We find remarkably good agreement between the predicted $L_{\rm x}$ and the observed values for partially convective stars. However, for fully convective stars at ages of a few billion years, the constructed $L_{\rm x}-$age relation overpredicts the X-ray luminosity because the angular momentum evolution model underpredicts the rotation period of these stars. Finally, we examine the effect of different parameterizations for the Rossby number ($R_{\rm O}$) on the shape of the activity-rotation relation in $L_{\rm x}/L_{\rm bol}-R_{\rm O}$ space, and we find that the slope in the unsaturated regime and the location of the break point of the dual power-law depend sensitively on the choice of $R_{\rm O}$.

description: Student evaluation of teaching (SET) is employed as an aid in improving instruction and determining faculty teaching effectiveness. However, economic theory indicates the existence of externalities in SET scores that directly influence their interpretation. As a test of this existence, a multinomial-choice, ordered data estimation procedure is employed to identify course externalities influencing SET. These externalities include student class standing, required courses, class size, days a class meets, class meeting time, classroom location, and classroom design. Results indicate that externalities have a significant impact on teaching evaluations. Thus, failure to internalize these externalities will lead to biases in SET and questionable use of SET as an aid in instruction improvement and determining faculty effectiveness.
Spectrum of Very High Energy Gamma-Rays from the blazar 1ES1959+650 during Flaring Activity in 2002

description: The blazar 1ES 1959+650 was observed in a flaring state with the Whipple 10 m Imaging Atmospheric Cherenkov Telescope during May of 2002. A spectral analysis has been carried out on the data from that time period and the resulting very high energy gamma-ray spectrum ($E \geq 316$ GeV) can be well fit by a power-law of differential spectral index α= 2.78 +/- 0.12_{stat.} +/- 0.21_{sys.}. On June 4th 2002, the source flared dramatically in the gamma-ray range without any coincident increase in the X-ray emission, providing the first unambiguous example of an `orphan' gamma-ray flare from a blazar. The gamma-ray spectrum for these data can also be described by a simple power-law fit with α= 2.82 +/- 0.15_{stat.} +/- 0.30_{sys.}. There is no compelling evidence for spectral variability, or for any cut-off to the spectrum.

description: We consider a trace theorem for self-similar Dirichlet forms on self-similar sets to self-similar subsets. In particular, we characterize the trace of the domains of Dirichlet forms on the Sierpinski gaskets and the Sierpinski carpets to their boundaries, where boundaries mean the triangles and rectangles which confine gaskets and carpets. As an application, we construct diffusion processes on a collection of fractals called fractal fields, which behave as the appropriate fractal diffusion within each fractal component of the field.

New production channels for light dark matter in hadronic showers

description: Hadronic showers transfer a relevant amount of their energy to electromagnetic subshowers. We show that the generation of "secondary" dark photons in these sub-showers is significant and typically dominates the production at low dark photon masses. The resulting dark photons are however substantially less energetic than the ones originating from mesons decay. We illustrate this point both semi-analytically and through Monte Carlo simulations. Existing limits on vector-mediator scenarios for light dark matter are updated with the inclusion of the new production processes.
