title: Dietary Supplementation With Tart Cherries for Prevention of Inflammation-Associated Colorectal Cancer in Mice
Creators: name: Hunter, Ashlie
Publisher: name: Utah State University
Year: 2017

description: The cherry fruit is a nutrient-dense food with comparatively low caloric content and significant amounts of key nutrients and bioactive food chemicals. Much of the health benefit of cherries is attributed to their high amounts of anthocyanins, which have anti-oxidant and anticancer properties that contribute to changes in cell signaling pathways involved in inflammation, carcinogenesis and angiogenesis. In this project, we aimed to determine whether dietary supplementation with tart cherries prevents colon tumor development in mice consuming a Western diet compared to a prudent diet. Previously, our research team developed the Total Western Diet (TWD) for mice to emulate typical U.S. nutrition with respect to macro- (sugars, fats, and protein) and micronutrient (vitamin and mineral) contents. Incorporating the TWD in pre-clinical studies allows for the analysis of the impact dietary bioactives or functional foods on tumor development in a physiological environment that reflects nutritional patterns of the average American. We hypothesized that dietary supplementation with freeze-dried whole tart cherries would suppress development of colon tumors in a model of inflammation-associated colorectal cancer. A 2x2 factorial design was employed, whereby mice were fed either AIN93G (optimized for rodent health) or the TWD, each with and without Montmorency tart cherry powder added to the diet for a total anthocyanin content of 188 mg/kg diet. Mice were initiated with 10 mg/kg azoxymethane and provided 1% dextran sodium sulfate (DSS) in their drinking water for 4 weeks to promote colonic inflammation and tumorigenesis. Necropsy and tumor assessment was performed after 15 weeks of treatment. TWD consumption markedly enhanced colitis activity (40-fold increase) compared to mice fed AIN93G. Moreover , TWD-fed mice had significantly higher histopathology scores for inflammation and mucosal injury during the period of colitis and, importantly, during the recovery phase of this disease model. Colonic inflammation in TWD-fed mice persisted to the end of the study (day 105), whereas mucosa! injury (save for sites of neoplasia) had resolved. Also, as expected based on prior studies, mice fed TWD had higher tumor multiplicity (near 6-fold increase) compared consumption of the AIN93G diet. The most important observation in this study was that supplementation with tart cherry powder caused a significant 40% reduction (p
A Viable Randall-Sundrum Model for Quarks and Leptons with T' Family Symmetry

description: We propose a Randall-Sundrum model with a bulk family symmetry based on the double tetrahedral group, T', which generates the tri-bimaximal neutrino mixing pattern and a realistic CKM matrix, including CP violation. Unlike 4D models where the generation of mass hierarchy requires additional symmetry, the warped geometry naturally gives rise to the fermion mass hierarchy through wavefunction localization. The T' symmetry forbids tree-level flavor changing neutral currents in both the quark and lepton sectors, as different generations of fermions are unified into multiplets of T'. This results in a low first KK mass scale and thus the model can be tested at collider experiments.

title: Delay Discounting Mechanisms in Eating Disorders: A Call to Arms
Creators: name: Crowder, Rowan
Publisher: name: Utah State University
Year: 2017

description: Delay discounting, or temporal discounting, is a measure of impulsivity that describes the devaluation of a reinforcer as a function of its receipt in time. Several studies have shown that individuals diagnosed with a variety of behavioral maladies such as obesity/over-eating, substance abuse, cigarette smoking, heavy drinking, and problematic gambling exhibit greater discounting rates. To be specific, they are more impulsive and less willing to wait for delayed reinforcement than healthy controls. Several of these studies have found that obese women discount at a steeper rate than non-obese women, similar results have been shown in binge eating disorder. The relationship between discounting and other topics relating to food and eating is well documented in the literature. However, after extensive literature review only one article pertaining to delay discounting and its implications in bulimia nervosa, and three articles pertaining to delay discounting and anorexia nervosa were found. The following is an exploratory paper analyzing and discussing the possible implications and relationships between characteristics of delay discounting and eating disorders seen in the current literature. Several of the observed relationships found in the literature may warrant further investigation to aid in our understanding of these disorders and possible novel treatments. A number of studies have shown that delay discounting can be reduced. If there is additional evidence of delay discounting’s role in eating disorders, it may be possible to develop new and effective therapeutic techniques to decrease or increase the discounting rates seen in these disorders.

description: Unraveling the geological processes ongoing at Io's numerous sites of active volcanism requires high spatial resolution to, for example, measure the areal coverage of lava flows or identify the presence of multiple emitting regions within a single volcanic center. In de Kleer et al. (2017) we described observations with the Large Binocular Telescope (LBT) during an occultation of Io by Europa at ~6:17 UT on 2015 March 08, and presented a map of the temperature distribution within Loki Patera derived from these data. Here we present emission maps of three other volcanic centers derived from the same observation: Pillan Patera, Kurdalagon Patera, and the vicinity of Ulgen Patera/PV59/N Lerna Regio. The emission is localized by the light curves and resolved into multiple distinct emitting regions in two of the cases. Both Pillan and Kurdalagon Paterae had undergone eruptions in the months prior to our observations, and the location and intensity of the emission is interpreted in the context of the temporal evolution of these eruptions observed from other facilities. The emission from Kurdalagon Patera is resolved into two distinct emitting regions separated by only a few degrees in latitude that were unresolved by Keck observations from the same month.
title: Teaching Social Studies Through Drama
Creators: name: Anderson, Colin
Publisher: name: Utah State University
Year: 2017

description: Educators and researchers have long discussed methods for improving student achievement in the social studies and history. Research on student attitudes reveals that the social studies suffers from a lack of interest among students . Common complaints among students are that the subject is tedious , does not relate to their lives, is not particularly useful for their future careers, is repetitive, or that it is simply boring (Schug et al., 1982}. Even when students recognize the utilitarian value of skills they learn from social studies/ history, they rarely express an interest in the subject (Chiodo, 2004). After reviewing the body of literature on student attitudes towards the social studies, Shaughnessy and Haladyna (1985} concluded , "most students in the United States, at all grade levels, find social studies to be one of the least interesting, most irrelevant subjects in the school curriculum" (p. 694). Russel and Waters (2010) linked these attitudes to the prevalence of passive learning (lecture, worksheets and other busy work , and rote memorization) within contemporary social studies classrooms.
title: Relative Effects of Sleep Hygiene Behavior and Physical Exercise on Sleep Quality
Creators: name: Dopp, Austin
Publisher: name: Utah State University
Year: 2017

description: Numerous studies have shown the relationship between sleep and overall health. A common measure of sleep is sleep quality which has been shown to be influenced by a variety of factors such as physical activity, diet, stress, social engagement, cognitive stimulating, and sleep hygiene behaviors. Data was analyzed from a previous study to determine whether trying to change one’s sleep would improve sleep quality and if this was more effective than physical exercise. A group of 104 individuals, randomized to the treatment group, were asked to log their daily activities, via smartphone app, within these six behavioral domains for six months. Behavioral change scores were computed as the difference between six-month behavioral level and baseline behavioral level, for each of the six domains.Factor analysis that revealed that two latent factors explained the majority of the variance in behavioral change,with a "Physical Body Related behavior change”factor ("Physical") and a "Mental/Emotional" behavior change factor ("Mental"). In linear regression models,Physical significantly predicted sleep quality improvement over the six months (p=.029),but Mental did not(p=.606). In the middle aged adults in this study, the behavioral change pattern of increasing diet quality and physical activity,significantly predicted improvements in sleep quality. While efforts to improve one's cognitive and emotional well-being were not found to predict to sleep improvement, they still may be important for cognitive health overall.This information can prove useful as different interventions and programs are implemented to improve sleep in the population.
Transfer and einstellung effects of examples on devising computer algorithms
Creators: name: Goddard, William
Publisher: name: University of British Columbia
Year: 2010

description: This study was motivated by the writer's observation that the provision of solved examples to students learning to devise computer algorithms did not assist and even seemed to hinder in the development of such skills. It was surmised that this might be due to a number of factors. The learner might be delayed in hiso.development of the heuristics necessary to create algorithms using self-generated mediators. He might be misled in his expectation of the difficulty of performing such tasks independently. He might display rigidity (an Einstellung effect) in his later use of the techniques demonstrated by previously provided examples. Grade nine students were assigned to two groups at random. Both groups were given a printed introduction to computer program writing in the BASIC language and were asked to solve two problems, an easy problem and a harder criterion problem. Before the problems were assigned one group was given a solved example which was very similar to the easy problem. The second group was given a short history of computers to read. A Chi-square- test was used to test each of the following hypotheses: 1. The first problem was easier than the second problem for all students. 2. The example helped the first group in doing the easy problem comparing the proportion of correct solutions to the easy problem in each group. 3. The second group had a higher proportion of correct solutions for the "hard" problem than the first group. k. The second group had a higher proportion of correct solutions for the "hard" problem than the first group when only those students who correctly solved the first problem were considered. The first, second, and fourth hypotheses were found to be significant beyond the .05 level. The conclusion was drawn that the use of examples to teach algorithm development on the computer is at least sometimes inadvisable in that examples may hinder transfer of training from easy problems to harder problems and do not increase the numbers who can independently solve a harder problem. (This assumes that the independent solution of harder problems is the only instructional goal.) At best the provision of such examples may be a waste of time, at worst it may be a distraction. It was felt that further research using a greater number and variety of examples, classified in some way, and using a variety of textual material is both warranted and desirable. It was also felt that a test instrument could he devised which would identify those students who would most benefit from a course in algorithm development on the computer.
title: Running in REM Cycles: Escapism in the French Postwar Films Le Silence de la Mer and la Vache et le Prisonier
Creators: name: Green, Danielle
Publisher: name: Utah State University
Year: 2017

description: This thesis compares two postwar critiques of escapist entertainment that appear in Jean-Pierre Melville's Le Silence de La Mer (1949), and Henri Verneuil's La Vache et le Prisonnier (1959). Their directorial choices acknowledge the power, even shortcomings of escapism through entertainment. Overall, Melville and Verneuil's films argue that escapism creates a "dream" cycle in which the audience, in an attempt to escape reality through entertainment. The films' cyclical narrative structures symbolize their characters' psychology, a tactic that frames Le Silence and La Vache into France's postwar culture. In a side-by-side comparison, the repetitive narrative structure of Le Silence and La Vache demonstrates that there was no escape from the war, mentally or physically. In addition to the films' structures, their inverted genre conventions are also didactic. They send a message to the audience that a story's resolution does not translate to reality, and sometimes, after much effort, resolution cannot be attained. The unfulfilling character arcs for each main character, Werner and Charles, are evidence of this grounded commentary on escapist entertainment. In addition to being similar, these character arcs reflect a continuation of one narrative. Despite being in two different genres, Charles's struggle is a sequel to Werner's. This comprehensive examination of the two films describes the several different layers of escapism that French postwar cinema either presented or critiqued.

description: We report on antiferroelectriclike double polarization hysteresis loops in multiferroic HoMnO3 thin films below the ferroelectric Curie temperature. This intriguing phenomenon is attributed to the domain pinning by defect dipoles which were introduced unintentionally during film growth process. Electron paramagnetic resonance suggests the existence of Fe1+ defects in thin films and first principles calculations reveal that the defect dipoles would be composed of oxygen vacancy and Fe1+ defect. We discuss migration of charged point defects during film growth process and formation of defect dipoles along ferroelectric polarization direction, based on the site preference of point defects. Due to a high-temperature low-symmetry structure of HoMnO3, aging is not required to form the defect dipoles in contrast to other ferroelectrics (e.g., BaTiO3).

description: Anisotropic magnetic properties of single crystalline RAu_{2}Ge_{2} (R = La, Ce and Pr) compounds are reported. LaAu_{2}Ge_{2} exhibit a Pauli-paramagnetic behavior whereas CeAu_{2}Ge_{2} and PrAu_{2}Ge_{2} show an antiferromagnetic ordering with N\grave{e}el temperatures T_{N} = 13.5 and 9 K, respectively. The anisotropic magnetic response of Ce and Pr compounds establishes [001] as the easy axis of magnetization and a sharp spin-flip type metamagnetic transition is observed in the magnetic isotherms. The resistance and magnetoresistance behavior of these compounds, in particular LaAu_{2}Ge_{2}, indicate an anisotropic Fermi surface. The magnetoresistivity of CeAu_{2}Ge_{2} apparently reveals the presence of a residual Kondo interaction. A crystal electric field analysis of the anisotropic susceptibility in conjunction with the experimentally inferred Schottky heat capacity enables us to propose a crystal electric field level scheme for Ce and Pr compounds. For CeAu_{2}Ge_{2} our values are in excellent agreement with the previous reports on neutron diffraction. The heat capacity data in LaAu_{2}Ge_{2} show clearly the existence of Einstein contribution to the heat capacity.

description: CTA 102 is a blazar implying that its relativistic jet points towards Earth and emits synchrotron radiation produced by energetic particles gyrating in the magnetic field. This study aims to figure out the physical origins of radio flares in the jet, including the connection between the magnetic field and the radio flares. The dataset in the range 2.6-343.5 GHz was collected over a period of 5.5 years (2012 November 20-2018 September 23). During the data collection period, seven flares at 15 GHz with a range of the variability time-scale of roughly 26-171 days were detected. The quasi-simultaneous radio data were used to investigate the synchrotron spectrum of the source. We found that the synchrotron radiation is self-absorbed. The turnover frequency and the peak flux density of the synchrotron self-absorption (SSA) spectra are in the ranges of 42-167 GHz and 0.9-10.2 Jy, respectively. From the SSA spectra, we derived the SSA magnetic field strengths to be 9.20 mG, 12.28 mG, and 50.97 mG on 2013 December 24, 2014 February 28, and 2018 January 13, respectively. We also derived the equipartition magnetic field strengths to be in the range 24-109 mG. The equipartition magnetic field strengths are larger than the SSA magnetic field strengths in most cases, which indicates that particle energy mainly dominates in the jet. Our results suggest that the flares in the jet of CTA 102 originated due to particle acceleration. We propose the possible mechanisms of particle acceleration.

description: Following the Dirac-Frenkel time-dependent variational principle, dynamics of a one-dimensional Holstein polaron is probed by employing the Davydov D2 Ansatz with two sets of variational parameters, one for each constituting particle in the exciton-phonon system, and a simplified variant of the Davydov D1 Ansatz, also known as the $\tilde{D}$ Ansatz, with an additional set of phonon displacement parameters. A close examination of variational outputs from the two trial states reveals fine details of the polaron structure and intricacies of dynamic exciton-phonon interactions. Superradiance coherence sizes, speeds of exciton-induced phonon wave packets, linear optical absorption, and polaron energy compositions are also included in the study.

description: Within the field of Communication Studies, researchers attempt to define culture and often explain it as shared meanings and values among a group of people. Another subsection of Communication Studies includes the study of how images communicate: the field of visual rhetoric. This paper combines concepts from intercultural communication and visual rhetoric in order to better understand German culture. By examining two culturally significant eras of German artwork through the lens of visual rhetoric analysis, this study seeks to better understand German culture and its values. By analyzing the visual communication of historically significant photographs, one can find common meanings and values deemed important by the nations as a whole. The images both depict pre-existing cultural values and can also alter cultural norms through the depiction of values as being desirable or undesirable.
Full Salpeter Equation with Confining Interactions: Analytic Stability Proof

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The most popular 3-dimensional reduction of the Bethe-Salpeter formalism for the description of bound states within quantum field theory is the Salpeter equation, found as the instantaneous limit of the Bethe-Salpeter framework if allowing, in addition, for free propagation of the bound-state constituents. Unfortunately, depending on the Lorentz nature of the Bethe-Salpeter kernel, supposedly stable results of Salpeter's equation with confining interactions exhibit (un-)expected instabilities, probably related to Klein's paradox. Clearly, bound states may be regarded as stable if, for appropriate interactions, their mass eigenvalues belong to a real and discrete (part of the) spectrum that is bounded from below. Some general features of the eigenvalue spectra of any Salpeter equation are well-established: all bound-state masses squared are real and, for a large class of sufficiently reasonable Bethe-Salpeter kernels - which includes all interactions of phenomenological relevance for QCD -, the spectrum of mass eigenvalues consists, in the complex bound-state mass plane, at most of real pairs of opposite sign and imaginary points. For time-component vector harmonic-oscillator kernels, a straightforward stability proof is given.

Fermion flavor mixing in models with dynamical mass generation

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We present a model-independent method of dealing with fermion flavor mixing in the case when instead of constant, momentum-independent mass matrices one has rather momentum-dependent self-energies. This situation is typical for strongly coupled models of dynamical fermion mass generation. We demonstrate our approach on the example of quark mixing. We show that quark self-energies with a generic momentum dependence lead to an effective Cabibbo-Kobayashi-Maskawa (CKM) matrix, which turns out to be in general non-unitary, in accordance with previous claims of other authors, and to non-trivial flavor changing electromagnetic and neutral currents. We also discuss some conceptual consequences of the momentum-dependent self-energies and show that in such a case the interaction basis and the mass basis are not related by a unitary transformation. In fact, we argue that the latter is merely an effective concept, in a specified sense. While focusing mainly on the fermionic self-energies, we also study the effects of momentum-dependent radiative corrections to the gauge bosons and to the proper vertices. Our approach is based on an application of the Lehmann-Symanzik-Zimmermann (LSZ) reduction formula and for the special case of constant self-energies it gives the same results as the standard approach based on the diagonalization of mass matrices.

Publisher: name: Utah State University
Year: 2015

description: The disciplines of business and school administration are recognized as distinct and separate in purpose, product, and operation. While fundamental differences do exist between the two, school administrators have a need for application of business principles in order to manage an educational institution. Schools are, at their foundation, organizations relying on effective management, budgeting, public relations, value creation, etc. Despite this need, school administrators often come from backgrounds in teaching rather than management.
Research was conducted from secondary sources and personal interviews with teachers, university professors, and school administrators to examine the similarities between administration in business and schools. The purpose of the research was to determine where and how the knowledge of various business disciplines can assist in the successful management of educational institutions.
The thesis examines the business knowledge, skills, and abilities most important to a school administrator and suggests the tangible benefits that may be achieved when school administrators have proper training and education in both teaching and business administration. Further research may help determine specific ways that application of business principles may resolve problems in schools' operation and organization.

Furthermore, a more conceptual re-formulation for the image conjecture [Z3] is also given in terms of the deformed algebras. Consequently, the well-known Jacobian conjecture [Ke] is reduced to an open problem on this deformation of polynomial algebras.

Publisher: name: Utah State University

description: The U.S. Secret Service (USSS), one of the most elite security agencies in the world, is charged with protecting the President of the United States at any cost. Three American presidents fell to assassins' bullets before the USSS was assigned the role of presidential protection; one more would later be slain despite USSS protection. This study examines the organizational culture of the USSS, employing the methodology of cultural topography (CTOPS) to identify the agency's norms, values, identity, and perceptual lens. We review three of the most impactful twentieth-century assassination attempts-two failed, one successful-and their formative effect on USSS organizational culture. Beginning with the lesser-known plot to assassinate Harry Truman, we examine the permanent authorization of the Presidential Protective Division. We apply our main focus to the assassination of John Kennedy, the USSS's darkest hour and still its most powerful motivator. Lastly, we review the attack on Ronald Reagan and the development of the modern motivator. Lastly we review the attack on Ronald Reagan and the development of the modern USSS security apparatus. Our final profile of USSS organization culture gives insight into the agency's strengths and weaknesses and highlights the emergent challenges of the 21st century.

description: We provide a systematic approach to obtain formulas for characters and Kostant ${\mathfrak u}$-homology groups of the oscillator modules of the finite dimensional general linear and ortho-symplectic superalgebras, via Howe dualities for infinite dimensional Lie algebras. Specializing these Lie superalgebras to Lie algebras, we recover, in a new way, formulas for Kostant homology groups of unitarizable highest weight representations of Hermitian symmetric pairs. In addition, two new reductive dual pairs related to the above-mentioned ${\mathfrak u}$-homology computation are worked out.
Comparative study of the life history tactics of two species of marine intertidal isopods
Creators: name: Buskey, Edward Joseph
Publisher: name: University of British Columbia
Year: 2010

description: Advocates of the theory of r-K selection claim that high levels of density-independent mortality select for a high intrinsic rate of natural increase (r- strategist), while density-dependent mortality selects for greater competitive ability and a higher carrying capacity (K- strategist). Furthermore, environmental stability is thought to affect the amount of density-independent or density-dependent mortality that a species encounters with unpredictable and highly variable environments leading primarily to density-independent mortality, and more predictable, less variable environments leading primarily to density-dependent mortality. Species can be positioned on an r-K continuum on the basis of several life history characteristics which are correlated to the intrinsic rate of natural increase. Thus it is suggested that selection should favour rapid development, single reproduction, early maturity, smaller body size, and higher birth rate for r- strategists, and slower development, repeated reproduction, later maturity, larger body size and lower birth rates for K-strategists. I compared two species of isopods from the upper and lower intertidal zone for the reproductive parameters correlated with high intrinsic rate of increase. I considered the upper intertidal environment to be more variable and unpredictable because of the increased time of exposure to air, and the resulting changes in temperature and humidity, compared to the more stable conditions which exist when submerged. Thus the species from the upper intertidal, Idotea wosnesenskii, was expected to have life history characteristics which were r- selected with respect to those of Idotea montereyensis, from the lower intertidal. I found the differences in two of the correlates to be in the direction predicted by r- and K- selection, two other correlates to be in the opposite direction, and a fifth not to differ between the two species. By ranking these parameters with respect to their influence on the intrinsic rate of population increase, I found the two most important parameters, age of first reproduction and birth rate, to support the predictions of r-K theory, and I concluded that I. wosnesenskii was an r- strategist relative to I. montereyensis. Reproductive effort, the proportion of food energy resources allocated to reproduction, was also used as a measure of a species' position on the r-K continuum. Three different measures of reproductive effort supported the prediction of r-K theory, and showed that I. wosnesenskii had a higher reproductive effort that did I. montereyensis.

description: We study the light quark mass dependence of the f_0(600), kappa(800), rho(770) and K*(892) resonance parameters generated from elastic meson-meson scattering using unitarized one-loop Chiral Perturbation Theory. First, we show that it is possible to fit simultaneously all experimental scattering data up to 0.8-1 GeV together with lattice results on decay constants and scattering lengths up to a pion mass of 400 MeV, using chiral parameters compatible with existing determinations. Then, the strange and non-strange quark masses are varied from the chiral limit up to values of interest for lattice studies. In these amplitudes, the mass and width of the rho(770) and K*(892) present a similar and smooth quark mass dependence. In contrast, both scalars present a similar non-analyticity at high quark masses. Nevertheless, the f_0(600) dependence on the non-strange quark mass is stronger than for the kappa(800) and the vectors. We also confirm the lattice assumption of quark mass independence of the vector two-meson coupling that, in contrast, is violated for scalars. As a consequence, vector widths are very well approximated by the KSRF relation, and their masses are shown to scale like their corresponding meson decay constants.

title: Cultural Influences on Women in Leadership: An Extension of the Hofstede and Globe Dimensions

description: Technology has forever changed the face of business. Although in the past business markets have been limited to local geographic areas, the concept of outsourcing has opened a diverse spectrum of international markets. An increase in supplies and consumers can improve business effectiveness and efficiency, but entering international markets can be detrimental if the business is unaware of the subtle differences the new market has in regard to leadership styles and cultural values. Hofstede's cultural dimension analysis has been the primary research study for many industry and academic professionals (Bond 2002; Hofstede 1997). However, many scholars are questioning whether Hofstede and the GLOBE study and narrows in on the effects culture has on women pursing leadership, particularly women already labeled as leaders. Seventy-two women from thirty-one different countries attending the 2014 Insight Dubai Conference were surveyed.

description: Reconfiguration problems require finding a step-by-step transformation between a pair of feasible solutions for a particular problem. The primary concern in Theoretical Computer Science has been revealing their computational complexity for classical problems. This paper presents an initial study on reconfiguration problems derived from a submodular function, which has more of a flavor of Data Mining. Our submodular reconfiguration problems request to find a solution sequence connecting two input solutions such that each solution has an objective value above a threshold in a submodular function $f: 2^{[n]} \to \mathbb{R}_+$ and is obtained from the previous one by applying a simple transformation rule. We formulate three reconfiguration problems: Monotone Submodular Reconfiguration (MSReco), which applies to influence maximization, and two versions of Unconstrained Submodular Reconfiguration (USReco), which apply to determinantal point processes. Our contributions are summarized as follows: 1. We prove that MSReco and USReco are both $\mathsf{PSPACE}$-complete. 2. We design a $\frac{1}{2}$-approximation algorithm for MSReco and a $\frac{1}{n}$-approximation algorithm for (one version of) USReco. 3. We devise inapproximability results that approximating the optimum value of MSReco within a $(1-\frac{1+ε}{n^2})$-factor is $\mathsf{PSPACE}$-hard, and we cannot find a $(\frac{5}{6}+ε)$-approximation for USReco. 4. We conduct numerical study on the reconfiguration version of influence maximization and determinantal point processes using real-world social network and movie rating data.

New Constraints on Hidden Photons using Very High Energy Gamma-Rays from the Crab Nebula

description: Extensions of the standard model of particle physics, in particular those based on string theory, often predict a new U(1) gauge symmetry in a hidden sector. The corresponding gauge boson, called hidden photon, naturally interacts with the ordinary photon via gauge kinetic mixing, leading to photon - hidden photon oscillations. In this framework, one expects photon disappearance as a function of the mass of the hidden photon and the mixing angle, loosely constrained from theory. Several experiments have been carried out or are planned to constrain the mass-mixing plane. In this contribution we derive new constraints on the hidden photon parameters, using very high energy gamma-rays detected from the Crab Nebula, whose broad-band spectral characteristics are well understood. The very high energy gamma-ray observations offer the possibility to provide bounds in a broad mass range at a previously unexplored energy and distance scale. Using existing data that were taken with several Cherenkov telescopes, we discuss our results in the context of current constraints and consider the possibilities of using astrophysical data to search for hidden photon signatures.

description: This paper addresses the role of product liability for the emergence and development of smart products such as autonomous vehicles (AVs). We analyze how the liability regime affects innovative activities, as well as the timing of market introduction and market penetration of such smart products. We develop a dynamic model in which at each point in time, a potential (monopolistic) innovator decides on how much to invest in the safety stock of the smart product and on the product price, once it has been launched. Calibrating the model to the U.S. car market, our analysis reveals policy-relevant trade-offs when shifting more liability on the producers of AVs. First, while this improves the safety of AVs in the long run, the safety stock is accumulated more slowly. Second, it delays the market introduction of AVs, and also slows down market penetration, which hampers the innovator’s incentives for safety investments in the short- and intermediate term. As a result, the safety level of AVs at a given point in time decreases as the liability regime becomes more stringent. Furthermore, there is a threshold for the innovator’s burden of liability beyond which she forgoes to develop the AV altogether. Finally, we find that direct AV safety regulation is welfare-superior compared to a stringent liability regime, as it induces higher levels of AV safety in the short and intermediate term.

description: We present a method for parametric modelling of the physical components of the Galaxy's magnetised interstellar medium, simulating the observables, and mapping out the likelihood space using a Markov Chain Monte-Carlo analysis. We then demonstrate it using total and polarised synchrotron emission data as well as rotation measures of extragalactic sources. With these three datasets, we define and study three components of the magnetic field: the large-scale coherent field, the small-scale isotropic random field, and the ordered field. In this first paper, we use only data along the Galactic plane and test a simple 2D logarithmic spiral model for the magnetic field that includes a compression and a shearing of the random component giving rise to an ordered component. We demonstrate with simulations that the method can indeed constrain multiple parameters yielding measures of, for example, the ratios of the magnetic field components. Though subject to uncertainties in thermal and cosmic ray electron densities and depending on our particular model parametrisation, our preliminary analysis shows that the coherent component is a small fraction of the total magnetic field and that an ordered component comparable in strength to the isotropic random component is required to explain the polarisation fraction of synchrotron emission. We outline further work to extend this type of analysis to study the magnetic spiral arm structure, the details of the turbulence as well as the 3D structure of the magnetic field.
