description: While lateral interaction models for reactions at surfaces have steadily gained popularity and grown in terms of complexity, their use in chemical kinetics has been impeded by the low performance of current KMC algorithms. The origins of the additional computational cost in KMC simulations with lateral interactions are traced back to the more elaborate Cluster Expansion Hamiltonian, the more extensive rate updating, and to the impracticality of rate-catalog-based algorithms for interacting adsorbate systems. Favoring instead site-based algorithms, we propose three ways to reduce the cost of KMC simulations: 1. Represent the lattice energy by a smaller Supercluster Hamiltonian without loss of accuracy, 2. employing Subtraction Schemes for updating key quantities in the simulation that undergo only small, local changes during a reaction event, and 3. applying efficient search algorithms from a set of established methods (Supersite Approach). The resulting algorithm is fixed-cost with respect to the number of lattice sites for practical lattice sizes and scales with the square of the range of lateral interactions. The overall added cost of including a complex lateral interaction model amounts to less than a factor 3. Practical issues in implementation due to finite numerical accuracy are discussed in detail, and further suggestions for treating long-range lateral interactions are made. We conclude that, while KMC simulations with complex lateral interaction models are challenging, these challenges can be overcome by modifying the established Variable Step Size Method by employing the Supercluster, Subtraction and Supersite algorithms (SSS-VSSM).

description: We present a general algorithm based on the concept of form-invariance which can be used for generating phantom cosmologies. It involves linear transformations between the kinetic energy and the potential of the scalar field, and transforms solutions of the Einstein-Klein-Gordon equations which preserve the weak energy condition into others which violate it, while keeping the energy density of the field positive. All known solutions representing phantom cosmologies are unified by this procedure. Using the general algorithm we obtain those solutions and show the relations between them. In addition, the scale factors of the product and seed solutions are related by a generalization of the well-known $a\to a^{-1}$ duality.

description: When comparing media coverage or analysing which content people are exposed to, researchers need to abstract from individual articles. At the same time, aggregating them into broad topics or issues often is too coarse and loses nuance. Both theoretically and methodologically, the analysis of an appropriate intermediate level of aggregation is underdeveloped. This article advances research in various areas of journalism studies by developing a theoretical argument for introducing the “news event” as a level of analysis. Based on this, we discuss several computational approaches to empirically detect such news events in large corpora of news coverage in an unsupervised manner. We provide two approaches: One based on traditional tf·idf based cosine similarities, and one that relies on word embeddings, in particular the softcosine measure. Both methods, combined with a network clustering algorithm, perform very well in detecting news events. We apply this method in a case study of 45k news articles from different outlets, in which we show that different news outlets have distinct profiles in the events they cover.

description: The timing argument provides a lower limit on the mass of the Milky Way. We find, using a sample of 32 stars at $R > 60$ kpc drawn from the H3 Spectroscopic Survey and mock catalogs created from published numerical simulations, that M$_{200} > 0.91\times 10^{12}$ M$_\odot$ with 90% confidence. We recommend using this limit to refine the allowed prior mass range in more complex and sophisticated statistical treatments of Milky Way dynamics. The use of such a prior would have significantly reduced many previously published uncertainty ranges. Our analysis suggests that the most likely value of M$_{200}$ is $\sim 1.4 \times 10^{12}$ M$_\odot$, but establishing this as the Milky Way mass requires a larger sample of outer halo stars and a more complete analysis of the inner halo stars in H3. The imminent growth in the sample of outer halo stars due to ongoing and planned surveys will make this possible.

Improving the Accuracy and Timeliness of Referral Triage for Patients with Lower Back Pain Referred to an Academic Medical Center’s Spine Center
Creators: name: Simms, Benjamin S
Publisher: name: University of Massachusetts Amherst
Year: 2022

Background: University Medical Center’s (UMC) current triage mechanism for adults with lumbar spine problems frequently triages patients to the wrong spine specialist with the wrong timing leading to decreased access and patient satisfaction. Purpose: This quality improvement (QI) project sought to improve the triage accuracy of referrals for adults with lumbar spine issues by implementing triage performed by a Nurse Practitioner (NP). NP based triage is an evidence-based practice to improve triage accuracy and increase access and patient satisfaction.  Methods: The NP triaged 95 incoming referrals for patients 18 years and older with lumbar spine problems using established triage guidelines by UMC and the Spine Severity Index. After the patient was seen by a spine specialist, agreement with the triage decision was assessed by surveying the provider. Wait times were measured during the NP led triage project. Spine specialist feedback was collected on 95 triaged patients. Concordance was measured using percentage agreement. Patient satisfaction scores were collected by a hospital-based survey system during the QI project. Results: The NP triage mechanism had a concordance score of 92.50% and the decision tree had a score of 63.04%. A Mann-Whitney U test revealed a statistically significant difference between the two triage mechanisms (Mann-Whitney U=1438.00, pConclusion:NP triage leads to more accurate triage than the decision tree method but did not have observed secondary effect on wait times or patient satisfaction. This is likely due to provider attrition and the COVID-19 pandemic.

description: Using an effective field theory approach, we address the effects on the gauge couplings of one and two additional compact dimensions in the presence of a constant background (gauge) field. Such background fields are a generic presence in models with extra dimensions and can be employed for gauge symmetry breaking mechanisms in the context of 4D N=1 supersymmetric models. The structure of the ultraviolet (UV) and infrared (IR) divergences that the gauge couplings develop in the presence of Wilson line vev's is investigated. One-loop radiative corrections to the gauge couplings due to overlapping effects of the compact dimensions and Wilson line vev's are computed for generic 4D N=1 models. Values of Wilson lines vev's corresponding to points (in the ``moduli'' space) of enhanced gauge symmetry cannot be smoothly reached {\it perturbatively} from those corresponding to the broken phase. The one-loop corrections are compared to their (heterotic) string counterpart in the ``field theory'' limit alpha'->0 to show remarkably similar results when no massless states are present in a Kaluza-Klein tower. An additional correction to the gauge coupling exists in the effective field theory approach when for specific Wilson lines vev's massless Kaluza-Klein states are present. This correction is not recoverable by the limit alpha'->0 of the (infrared regularised) string because the infrared regularisation limit and the limit alpha'->0 of the string result do not commute.

description: We study translationally invariant rings of qubits with a finite number of sites N, and find the maximal nearest-neighbor entanglement for a fixed z component of the total spin. For small numbers of sites our results are analytical. The use of a linearized version of the concurrence allows us to relate the maximal concurrence to the ground state energy of an XXZ spin model, and to calculate it numerically for N<25. We point out some interesting finite-size effects. Finally, we generalize our results beyond nearest neighbors.

description: Die vorliegende Bachelorarbeit setzt sich mit der Frage auseinander, welche Ansätze
und Rahmenbedingungen eine förderliche Reaktion auf abweichendes Verhalten in Jugendwohngruppen
ermöglichen. Insbesondere der Umgang mit traumatisierten Jugendlichen
stellt hohe Anforderungen an die Fachkompetenz und Reflexionsfähigkeit der Betreuenden.
Diese Bachelorarbeit untersucht Bestrafung als pädagogisches Instrument.
Dazu werden Argumentationen verschiedener Autorinnen und Autoren herangezogen.
Darüber hinaus werden exemplarisch drei alternative Ansätze betrachtet; die positive
Verstärkung, die neue Autorität und die psychoanalytische Pädagogik. Darüber hinaus
wird die Traumapädagogik näher betrachtet, insbesondere im Hinblick auf die Grundhaltungen.
Es wird aufgezeigt, welche Möglichkeiten bestehen, im Wohngruppenalltag ein
unterstützendes und stabiles Umfeld zu schaffen, das den Jugendlichen Entwicklungschancen
bietet. Ziel ist es, Strategien zu entwickeln, die verhindern, dass Jugendliche
aufgrund ihres Verhaltens von einer Institution zur nächsten wechseln müssen. Stattdessen
soll langfristige Stabilität und Integration gefördert werden.

description: With the increasing use of algorithms in news distribution, commentators warn about its possible impacts on the changing relationship between the news media and news readers. To understand the meaning of news personalisation strategies to users, we investigated how they currently experience news personalisation, perceive their role in the personalisation process, and envision increasing the utility of personalised news by giving users more agency and fostering trust. We conducted four focus groups with online news readers in Germany. For the analysis, grounded theory techniques were suitable due to their applicability in reconstructing user perspectives through their own experiences. We found that (1) users fail to distinguish between news personalisation and commercial targeting, which may negatively bias their perception; (2) there is a contradiction in how users perceive themselves as active participants in the process, but lack the means to exercise agency; (3) user concerns extend beyond privacy to what information they receive and their right to personal autonomy—a solution requires offering users the ability to dynamically adjust their “news interest profiles”; (4) while news personalisation strategies afford new opportunities for introducing reciprocity in the media-audience relationship, negotiating competing logics of journalistic, personal and algorithmic curation remains a challenge.

description: As algorithms are increasingly integrated into news selection and consumption processes, it is crucial to understand how news users respond to them. Drawing upon social cognitive theory, this study examined the underlying mechanisms of consumptive news feed curation, a type of news consumption behaviour through which news users could determine what shows up in their news feeds. Findings based on a national survey data in the United States showed that the proportion of Facebook users who practiced consumptive news feed curation remained low and the extent of such practices varied according to their socioeconomic and political backgrounds. The study further tested a moderated mediation model and found that Facebook use contributed to consumptive news feed curation through perceived knowledge, depending on levels of perceived user controllability. Theoretical and practical implications are discussed.
Fall Prevention Program for Adults with Intellectual Disabilities
Creators: name: ambroise, marie
Publisher: name: University of Massachusetts Amherst

Abstract
 
Background and Review of Literature: Adults with intellectual disabilities are vulnerable to falls. Proper intervention results in enhanced health outcomes. Implementing Otago Exercise Program (OEP), an evidence-based exercise intervention, has been shown to reduce fall rates among adults with ID. 
Purpose: To use evidence-based preventive measures for reducing falls among intellectually disabled mental health facility residents over the age of 55.
Methods: An OEP was provided to adults with Intellectual Disabilities aged 50 and above at a chronic mental health facility for eight weeks. The implementation involved four phases. Phase one included organizing meetings with stakeholders and gathering pre-intervention data. In phase two, staff were trained through pamphlets and educational sessions. Phase three involved the implementation of the project interventions. The intervention involved exercise and a walking program administered by the Doctor of Nursing Practice (DNP) student and physical therapists and direct care staff.
Results: The paired t-test demonstrated that there was a significant difference in Mores Fall Scale (MFS) scores before and after the implementation of OEP (Paired t=-2.96, p=.005). After OEP implementation, the MFS mean score was decreased from 11.22 (2.31) to 8.12 (2.19). Next, there was a fall rate reduction from 60% before implementation to 32% after implementation. Again, the self-report questionnaire results show significant improvement in staff’s knowledge of fall prevention practices. Finally, the Otago Exercise Program was well received by the nurses with almost all the nurses participating in the program from start to the end recording a 90% attendance.
Implications/Conclusion: The project's findings are likely to demonstrate the implementation of exercise and walking programs in reducing fall rates among adults with ID. The project may also have policy implications. Overall, the OEP portrayed a positive trend in improving staff knowledge and engagement of falls prevention practices. This project has shown the OEP is one of the preventive measures to help reduce falls among older people with ID.

description: This study investigates the rationality of monthly revisions in annual forecasts of supply, demand, and price for U.S. corn, cotton, soybeans, and wheat, published in the World Agricultural Supply and Demand Estimates over 1984/85 through 2011/12. The findings indicate that USDA’s forecast revisions are not independent across months, and that forecasts are typically smoothed. Adjustment for smoothing in a subset of forecasts (2002/03 – 2011/12) showed weak results: marginal improvements in accuracy were limited to wheat production and cotton production and domestic use while deterioration in accuracy was observed in all other cases. Smoothing coefficients were highly unstable over time. Case studies for corn focused on correction for a structural break and the impact of forecast size and direction, but did not lead to improvements in accuracy. Case studies for October revisions of soybean production forecasts suggest that ten year rolling estimation and correcting for outliers using leverage may help improve accuracy in the adjusted forecasts.
Improving Postpartum Screening Rates in Patients Diagnosed with Gestational Diabetes in Pregnancy
Creators: name: Doyle-Malone, Meaghan
Publisher: name: University of Massachusetts Amherst
Year: 2022

Background: Those diagnosed with gestational diabetes mellitus have a high chance of developing diabetes in the years following delivery.  People who live with undiagnosed diabetes are at high risk for developing cardiovascular disease, eye, kidney and nerve damage.  Glucose tolerance testing should be completed four to twelve weeks after delivery in anyone diagnosed with GDM, and even if screening is negative, it should be repeated every one to three years after. 
Purpose: In a chart audit of patients who delivered Fall 2020 at the facility, only 15% of patients with GDM were compliant with completing a 2-hour oral glucose tolerance test (OGTT) in the postpartum period.  The aim of this project was to increase completion of postpartum glucose screening to 50% for women four to 12-weeks postpartum over a 90-day period. 
Methods: This project was completed by tracking postpartum patients diagnosed with GDM in pregnancy, from October 2021 through December 2021, to assess the effect of the proposed interventions on improving screening rates at an urban medical center in Massachusetts.
Results: In the 257 women delivered during this time, 26 patients screened positive for GDM (10%) during their pregnancy.  An educational session was given on postpartum screening after which staff awareness of screening recommendations improved and the 2-hour OGTT rates increased from 15% to 55.5%.  There was also an increase in completed postpartum visits in GDM patients from 60% to 89% from the beginning of the project.
Conclusion: GDM screening increased by 40.5% at the end of the 90 days.  All of those who were screened and had abnormal 2-hour OGTTs were referred appropriately for follow up care.  An integral component of quality improvement as evident by this project is the importance of team engagement.
Mixing enhancement in binary fluids using optimised stirring strategies

description: Mixing of binary fluids by moving stirrers is a commonplace process in many industrial applications, where even modest improvements in mixing efficiency could translate into considerable power savings or enhanced product quality. We propose a gradient-based nonlinear optimization scheme to minimize the mix-norm of a passive scalar. The velocities of two cylindrical stirrers, moving on concentric circular paths inside a circular container, represent the control variables, and an iterative direct-adjoint algorithm is employed to arrive at enhanced mixing results. The associated stirring protocol is characterized by a complex interplay of vortical structures, generated and promoted by the stirrers' action. Full convergence of the optimization process requires constraints that penalize the acceleration of the moving bodies. Under these conditions, considerable mixing enhancement can be accomplished, even though an optimum cannot be guaranteed due to the non-convex nature of the optimization problem. Various challenges and extensions of our approach are discussed.

description: We consider the problem of incompressible, forced, nonhelical, homogeneous and isotropic MHD turbulence with no mean magnetic field and large magnetic Prandtl number. This type of MHD turbulence is the end state of the turbulent dynamo, which generates folded fields with small-scale direction reversals. We propose a model in which saturation is achieved as a result of the velocity statistics becoming anisotropic with respect to the local direction of the magnetic folds. The model combines the effects of weakened stretching and quasi-two-dimensional mixing and produces magnetic-energy spectra in remarkable agreement with numerical results at least in the case of a one-scale flow. We conjecture that the statistics seen in numerical simulations could be explained as a superposition of these folded fields and Alfvén-like waves that propagate along the folds.

After the projection of high dimensional microbiome profiles into a low dimensional space (such as PC1 and PC2 of PCoA), original variations might be lost. For example, two distinct clusters of samples (colored orange and blue) from the original space are superimposed on each other in the projection space. The clustering step of tmap performs clustering analysis using their original distances to recover the separated clusters from the original space. The recovered variation is captured by tmap in its network representation.

description: A coupling-constant definition is given based on the compositeness property of some particle states with respect to the elementary states of other particles. It is applied in the context of the vector-spin-1/2-particle interaction vertices of a field theory, and the standard model. The definition reproduces Weinberg's angle in a grand-unified theory. One obtains coupling values close to the experimental ones for appropriate configurations of the standard-model vector particles, at the unification scale within grand-unified models, and at the electroweak breaking scale.

description: While no consensus governs our understanding of the origin of low redshift radio galaxies, the possibility that mergers may trigger accretion from hot cluster halo gas has spurred a recent search for such signatures. Evidence for mergers is at best tenuous, however, and even when found, generates more questions than answers. With scant evidence for minor mergers, some connection to major mergers is found in isolated environments but not where one would expect, i.e. in clusters. We provide an explanation for these recent results by Gordon et al (2019) on the relevance of major mergers in low excitation radio galaxies (LERGs) at low redshift. While LERGs are not the direct result of a merger, we describe how they form in clusters in only a few million years while that timescale is an order of magnitude longer in field environments. As a result of these different timescales, the average lifetime of a cluster LERG is estimated at an order of magnitude greater value than for field LERGs. Observing a LERG in the cluster environment, therefore, will tend to occur when greater time has passed since the major merger event that produced its high excitation radio galaxy ancestor, such that fewer signatures of that event remain visible. We provide simple estimates for the fraction of LERGs as a function of environment that are directly related to these timescales, obtaining a probability of about 7% that field LERGs will show merger signatures and 3% for clusters, showing that theory and observation match if major merger signatures remain visible for a few hundred million years.

description: Unprecedented changes in commodity prices since 2004 have had worldwide repercussions, often acting as a destabilizing economic and political influence. In this paper, we use a recently developed multiple bubble testing procedures to detect and date-stamp bubbles in corn, soybean, and wheat futures markets. To account for conditional heteroskedasticity and small sample bias, inferences are derived using a recursive wild bootstrap procedure. We find that the markets experienced price explosiveness about 2% of the time. Using a logit model which accounts for bias due to the rare occurrence of an event, we find that bubbles are more likely to occur in the presence of large aggregate global demand, low stocks to use ratios, and a weak US dollar. While commodity index traders had no effect on the probability of an explosive episode, speculative activity exceeding the minimum level required to absorb hedging activities as measured by the Working’s T reduces considerably the probability of a bubble.

Phänomen Stigmatisierung: Stigmatisierung von Klient*innen mit einer Abhängigkeitserkrankung in der aufsuchenden Sozialen Arbeit
Creators: name: Tellenbach, Norina
Publisher: name: Hochschule Luzern – Soziale Arbeit
Year: 2025

description: Im Alltag werden wir kontinuierlich mit einer Vielzahl von Informationen konfrontiert, die wir zu ordnen und bewerten versuchen. Besonders herausfordernd wird dies, wenn es um Informationen über andere Menschen geht, da es wichtig ist, neutral zu bleiben und keine Vorurteile zu entwickeln, die zu einer Ausgrenzung bestimmter Gruppen führen könnten. Dies betrifft insbesondere Menschen mit einer Abhängigkeitserkrankung. Fachpersonen der aufsuchenden Sozialen Arbeit spielen hier eine entscheidende Rolle, da sie in einem Umfeld tätig sind, das sie vor diverse Herausforderungen stellt. Die vorliegende Arbeit von Norina Tellenbach, mit dem Titel "Phänomen Stigmatisierung – Stigmatisierung von Klient*innen mit einer Abhängigkeitserkrankung in der aufsuchenden Sozialen Arbeit", untersucht die Stigmatisierung von Klient*innen mit einer Abhängigkeitserkrankung und analysiert den Umgang mit diesem komplexen Phänomen.
Durch Literatur und die Arbeit in der Praxis wurden sowohl die Erfahrungen als auch der Umgang mit Klient*innen dieser Personengruppe untersucht. Auf diese Weise konnte ermittelt werden, welche Strategien auf institutioneller und individueller Ebene angewendet werden können, um Stigmatisierung zu begegnen.
Fachkräfte in der Sozialen Arbeit sind sich der zahlreichen Herausforderungen bewusst, die in diesem Bereich auftreten können. Deshalb streben sie stets an, ihre Handlungen kritisch zu reflektieren und nutzen unterschiedliche Strategien, um der Stigmatisierung entgegenzuwirken. Diese Bemühungen sind entscheidend, um stabile Beziehungen zu etablieren und einen erfolgreichen Umgang mit Stigmatisierung bzw. deren Prävention zu fördern.

description: We estimate the effect of electronic trade on the quality of price discovery in the Intercontinental Exchange cotton futures market. Between 2006 and 2009, this market transtioned from floor-only trade to parallel floor and electronic trade and then to electronic-only trade. We use a random-walk decomposition to separate intraday variation in cotton prices into two components: one related to information about market fundamentals and one a “pricing error” related to market frictions such as the cost of liquidity provision and the transient response of prices to trades. We find that on a typical day during the electronic-only period, the standard deviation of the pricing error is half what it was on a typical day during the floor-only period. This drop reflects a substantial improvement in average market quality, much of which is associated with an increase in the number of trades per day. We report three additional findings: (i) market quality was significantly more volatile during the electronic trading period than the prior periods meaning that there were more days with large deviations from average market quality, (ii) market quality was poor immediately following the closure of the floor and (iii) market quality was better on days when public information was released in the form of USDA crop reports but worse on days where prices change by the maximum imposed by the exchange.

description: In this paper we first give a one-move version of Markov's braid theorem for knot isotopy in $S^3$ that sharpens the classical theorem. Then a relative version of Markov's theorem concerning a fixed braided portion in the knot. We also prove an analogue of Markov's theorem for knot isotopy in knot complements. Finally we extend this last result to prove a Markov theorem for links in an arbitrary orientable 3--manifold.

Sigma and hydrodynamic modes along the critical line

description: Assuming a tricritical point of the two--flavor QCD in the space of temperature, baryon number chemical potential and quark mass, we study the change of the associated soft mode along the critical line within the Ginzburg--Landau approach and the Nambu--Jona-Lasinio model. The ordering density along the chiral critical line is the scalar density whereas a linear combination of the scalar, baryon number and energy densities becomes the proper ordering density along the critical line with finite quark masses. It is shown that the critical eigenmode shifts from the sigma--like fluctuation of the scalar density to a hydrodynamic mode at the tricritical point, where we have two ordering densities, the scalar density and a linear combination of the baryon number and energy densities. We argue that appearance of the critical eigenmode with hydrodynamic character is a logical consequence of divergent susceptibilities of the conserved densities.

description: We study the simulation of stellar mergers, which requires complex simulations with high computational demands. We have developed Octo-Tiger, a finite volume grid-based hydrodynamics simulation code with Adaptive Mesh Refinement which is unique in conserving both linear and angular momentum to machine precision. To face the challenge of increasingly complex, diverse, and heterogeneous HPC systems, Octo-Tiger relies on high-level programming abstractions. We use HPX with its futurization capabilities to ensure scalability both between nodes and within, and present first results replacing MPI with libfabric achieving up to a 2.8x speedup. We extend Octo-Tiger to heterogeneous GPU-accelerated supercomputers, demonstrating node-level performance and portability. We show scalability up to full system runs on Piz Daint. For the scenario's maximum resolution, the compute-critical parts (hydrodynamics and gravity) achieve 68.1% parallel efficiency at 2048 nodes.

Enhancing Preventative Health Care for Latino Migrant Dairy Farm Workers in Addison County, Vermont
Creators: name: Douglas, Elizabeth A
Publisher: name: University of Massachusetts Amherst
Year: 2022

Background: Latino dairy farmworkers, mainly from Mexico and Guatemala, help produce over 50% of Vermont’s milk. Latino dairy farmworkers may not seek health care for many reasons, including fear of immigration/law enforcement, language barriers, lack of transportation, and cost of care. Purpose: The purpose of this DNP project was to increase the utilization of health care services, including immunizations, of migrant farmers by educating and providing information about preventative, curative, and support services available in southern Vermont (VT). Methods: The intervention, one 60-minute educational program session took place at a local church service for migrant farmers, and an informational pamphlet was provided to the attendees. A DNP student-designed survey was administered to five farmers before and 5 weeks after an educational intervention took place in order to obtain health information. Descriptive statistics were used to analyze the data. Results: Health survey data showed that the participant’s healthcare knowledge increased by 0% for immunizations (100% pre- and 100% post- intervention), 40% for annual check-ups (60% pre- and 100% post- intervention), 20% for blood pressure checks (80% pre- and 100% post- intervention), 40% for diabetic screenings (40% pre- and 80% post- intervention), 20% for mammogram screenings (20% pre- and 40% post- intervention), and 20% for colonoscopies (0% pre- and 20% post- intervention. Additionally, their health status improved by 1.8 (6.2 vs. 8.0), and all participants reported that they used free health care clinics at pre- and post- intervention. Conclusion: Our project results suggest that the educational intervention was helpful in increasing healthcare knowledge and access among migrant farmworkers. Improving health care among migrant workers can assist with maintaining ethical living and working conditions, and it can help sustain local farming.

description: We study price discovery in the U.S. fed cattle market, examining the interaction among weekly live cattle futures, negotiated cash fed cattle, and boxed beef cutout prices. Extensive testing and innovation accounting based on directed acyclic graphs of error-correction resid- uals indicates that the futures price continues as the dominant source of information in the fed cattle market. While the cash cattle price has a strong predictive in_x000D_uence on the boxed beef price, the boxed beef price plays only a marginal role in price discovery.

description: We present the first application of the Basis Light-Front Quantization method to a simple chiral model of the nucleon-pion system as a relativistic bound state for the physical proton. The light-front mass-squared matrix of the nucleon-pion system is obtained within a truncated basis. The mass and the corresponding light-front wave function (LFWF) of the proton are computed by numerical diagonalization of the resulting mass-squared matrix. With the boost invariant LFWF, we calculate the probability density distribution of the pion's longitudinal momentum fraction and the Dirac form factor of the proton.

description: On 2014 March 29, an intense solar flare classified as X1.0 occurred in the active region 12017. Several associated phenomena accompanied this event, among them a fast-filament eruption, large-scale propagating disturbances in the corona and the chromosphere including a Moreton wave, and a coronal mass ejection. This flare was successfully detected in multiwavelength imaging in H-alpha line by the Flare Monitoring Telescope (FMT) at Ica University, Peru. We present a detailed study of the Moreton wave associated with the flare in question. Special attention is paid to the Doppler characteristics inferred from the FMT wing (H-alpha$\pm0.8$~Å) observations, which are used to examine the downward/upward motion of the plasma in the chromosphere. Our findings reveal that the downward motion of the chromospheric material at the front of the Moreton wave attains a maximum velocity of 4 km/s, whereas the propagation speed ranges between 640 and 859 km/s. Furthermore, utilizing the weak shock approximation in conjunction with the velocity amplitude of the chromospheric motion induced by the Moreton wave, we derive the Mach number of the incident shock in the corona. We also performed the temperature-emission measure analysis of the coronal wave based on the Atmospheric Imaging Assembly (AIA) observations, which allowed us to derive the compression ratio, and to estimate the Alfvén and fast-mode Mach numbers of the order of 1.06-1.28 and 1.05-1.27. Considering these results and the MHD linear theory we discuss the characteristics of the shock front and the interaction with the chromospheric plasma.
