description: A key component of mathematical reasoning is the ability to formulate interesting conjectures about a problem domain at hand. In this paper, we give a brief overview of a theory exploration system called QuickSpec, which is able to automatically discover interesting conjectures about a given set of functions. QuickSpec works by interleaving term generation with random testing to form candidate conjectures. This is made tractable by starting from small sizes and ensuring that only terms that are irreducible with respect to already discovered conjectures are considered. QuickSpec has been successfully applied to generate lemmas for automated inductive theorem proving as well as to generate specifications of functional programs. We give an overview of typical use-cases of QuickSpec, as well as demonstrating how to easily connect it to a theorem prover of the user's choice.

description: An argument of A.Borel shows that every compact connected Lie group is homeomorphic to the Cartesian product of its derived subgroup and a torus. We prove a parallel result for definably compact definably connected groups definable in an o-minimal expansion of a real closed field. As opposed to the Lie case, however, we provide an example showing that the derived subgroup may not have a definable semidirect complement.

title: Tutorial for Using the Center for High Performance Computing at The University of Utah and an example using Random Forest
Creators: name: Barton, Stephen
Publisher: name: Utah State University
Year: 2016

description: Random Forests are very memory intensive machine learning algorithms and most computers would fail at building models from datasets with millions of observations. Using the Center for High Performance Computing (CHPC) at the University of Utah and an airline on-time arrival dataset with 7 million observations from the U.S. Department of Transportation Bureau of Transportation Statistics we built 316 models by adjusting the depth of the trees and randomness of each forest and compared the accuracy and time each took. Using this dataset we discovered that substantial restrictions to the size of trees, observations allowed for each tree, and variables allowed for each split have little effect on accuracy but improve computation time by an order of magnitude.
Becoming familiar with the CHPC is significantly easier with the included tutorial at the end of the paper.

description: Mechanic antennas provide opportunities for human portable, VLF communications, where a rotational dipole emits EM signals with angular momenta. In this paper we analytically derive the electromagnetic fields from a rotational electric dipole using Fourier transform method, and find that the radiated fields from the rotational electric dipole carries nonzero energy flow density in both orbital and spin angular momentum (AM) parts by AM flux tensors. Intuitively, a rotation of a dipole induces a longitudinal orbital angular momentum and a longitudinal spin angular momentum both circulating in the rotation direction. And the binding force for the rotational electric dipole is then shown to result mainly from the Coulomb fields. We believe that our work can provide novel communication designs for portable mechanic antennas.

title: Enhancement of Volumetric Specific Impulse in HTPB/Ammonium Nitrate Mixed Hybrid Rocket Systems
Creators: name: Forsyth, Jacob Ward
Publisher: name: Utah State University
Year: 2016

description: Hybrid rocket systems are safer and have higher specific impulse than solid rockets. However, due to large oxidizer tanks and low regression rates, hybrid rockets have low volumetric efficiency and very long longitudinal profiles, which limit many of the applications for which hybrids can be used. This research investigates a method for increasing the volumetric efficiency and improving the form factor of hybrid rocket systems by a non-combustible load of solid oxidizer to the hybrid fuel grain. Including such oxidizers increases the regression rate of the fuel and lowers the amount of fluid oxidizer needed for optimal combustion. This type of solution is referred to as a “mixed hybrid”. Ammonium perchlorate is often the oxidizer of choice for these applications. However, ammonium perchlorate is extremely dangerous to work with and is an environmental pollutant. This study suggests the use of ammonium nitrate in place of ammonium perchlorate as a more environmentally friendly, lower risk oxidizer in mixed hybrid rocket systems. Presented results quantify the effects of ammonium nitrate in lab scale tests. Further research paths for ammonium nitrate mixed hybrids are outlined.

description: We study a phase transition in a 3D lattice gauge theory, a "coarse-grained" version of a classical dimer model. Duality arguments indicate that the dimer lattice theory should be dual to a XY model coupled to a gauge field with geometric frustration. The transition between a Coulomb phase with dipolar correlations and a long range ordered columnar phase is understood in terms of a Higgs mechanism. Monte Carlo simulations of the dual model indicate a continuous transition with exponents close but apparently different from those of the 3d XY model. The continuous nature of the transition is confirmed by a flowgram analysis.

title: The Garr Family Saga The Connecting Power of Oral Narrative
Creators: name: Jaggi, Margaret Garr
Publisher: name: Utah State University
Year: 2003

description: When I was a child, my mother often told me a "true" story about a beautiful Shoshone maiden who married a handsome American cowboy. The setting was the 1850s in the fertile valley of Cache County, Utah. The man's name was John Turner Garr and the woman was called Susie. This young couple was my paternal great-great grandparents. Together they lived a life that defied their disparate cultures. I envisioned them, young, wild, and free; he, dressed in buckskin leggings, riding among the Shoshone men; she, in soft doeskin supporting a papoose on her back. The idyllic life of my fantasy could, at best, only be temporary for them. It became for me, however, a catalyst that helped to form my own identity, and the identity of my family generations later.
Families tell stories such as this one to their children as a means to connect them to family identity and culture. The family is a child 's first culture. Families are the structures that give children their first perceptions of themselves. Through families, children are introduced to the narratives which confer upon them a sense of their place within the context of their environment. These narratives infuse in family members a collective understanding and a shared awareness of who they are and what they can become. From infancy on, cultural ideals and expectations are embedded in each family member through their family stories. "Family folklore may be said to be the first and basic dynamic traditional system encountered by most people the world over . . .. It is in this setting that we learn to participate in certain traditional roles. "1 These shared interpretations serve to bind the family as a cohesive unit. "There is no doubt that we learn about the idea of family and how to be a member of a family from our families ... family stories are one of the cornerstones of family culture; they throw what may be mute and habitual into sharp relief. By their presence, they say what issues -- from the most public and predictable to the most private and idiosyncratic -- really concern a given family.

description: Early-type stars show a bimodal distribution of magnetic field strengths, with some showing very strong fields ($\gtrsim 1\,\mathrm{kG}$) and others very weak fields ($\lesssim 10\,\mathrm{G}$). Recently, we proposed that this reflects the processing or lackthereof of fossil fields by subsurface convection zones. Stars with weak fossil fields process these at the surface into even weaker dynamo-generated fields, while in stars with stronger fossil fields magnetism inhibits convection, allowing the fossil field to remain as-is. We now expand on this theory and explore the time-scales involved in the evolution of near-surface magnetic fields. We find that mass loss strips near-surface regions faster than magnetic fields can diffuse through them. As a result, observations of surface magnetism directly probe the frozen-in remains of the convective dynamo. This explains the slow evolution of magnetism in stars with very weak fields: these dynamo-\emph{generated} magnetic fields evolve on the time-scale of the mass loss, not that of the dynamo.

description: It is widely accepted that the interaction of swift heavy ions with many complex oxides is predominantly governed by the electronic energy loss that gives rise to nanoscale amorphous ion tracks along the penetration direction. The question of how electronic excitation and electron–phonon coupling affect the atomic system through defect production, recrystallization, and strain effects has not yet been fully clarified. To advance the knowledge of the atomic structure of ion tracks, we irradiated single crystalline SrTiO₃ with 629 MeV Xe ions and performed comprehensive electron microscopy investigations complemented by molecular dynamics simulations. This study shows discontinuous ion-track formation along the ion penetration path, comprising an amorphous core and a surrounding few monolayer thick shell of strained/defective crystalline SrTiO₃. Using machine-learning-aided analysis of atomic-scale images, we demonstrate the presence of 4–8% strain in the disordered region interfacing with the amorphous core in the initially formed ion tracks. Under constant exposure of the electron beam during imaging, the amorphous part of the ion tracks readily recrystallizes radially inwards from the crystalline-amorphous interface under the constant electron-beam irradiation during the imaging. Cation strain in the amorphous region is observed to be significantly recovered, while the oxygen sublattice remains strained even under the electron irradiation due to the present oxygen vacancies. The molecular dynamics simulations support this observation and suggest that local transient heating and annealing facilitate recrystallization process of the amorphous phase and drive Sr and Ti sublattices to rearrange. In contrast, the annealing of O atoms is difficult, thus leaving a remnant of oxygen vacancies and strain even after recrystallization. This work provides insights for creating and transforming novel interfaces and nanostructures for future functional applications.

description: The article deals with the factors that influence the quality of the mechanical engineering process under conditions of make-to-order production. The authors analyze the existing approaches to the engineering processes quality assessment that is normally undertaken at the launch of the production process. The results show that it is necessary to account for some extra factors impacting the engineering process quality. Based on the analysis carried out a methodology is proposed that may help to select a rational type of the engineering process, which will be able to ensure the desired level of the produce quality.
Children’s beliefs about forces in equilibrium
Creators: name: Aguirre, Jose M.
Publisher: name: University of British Columbia
Year: 2010

description: Clinical interviews to explore children's beliefs about the concept of force were carried out with 32 children (18 boys, 14 girls), whose ages ranged from 6 to 14 years. Three tasks were used to investigate their beliefs about the action of a force, action and reaction, equilibrium of forces, and composition of forces. A conceptual profile was constructed on the aspects of force covered in the tasks. This conceptual profile was then used to categorize the children's beliefs which were uncovered in the interviews. It was found that the interview methodology was a feasible approach for an exploratory and descriptive study of students' beliefs about a particular concept and that the children in the sample had a set of typical a priori beliefs about force which they used to account for the different experimental situations. This set of beliefs was subsequently categorized in three levels of abstraction to bring to light the possible patterns of these beliefs. The children's ideas found in the study and the categorization of these into levels of abstraction could be useful for the curriculum developer and particularly for the teacher in planning teaching strategies.

description: Observations with the current generation of very-high-energy gamma-ray telescopes have revealed an astonishing variety of particle accelerators in the Milky Way, such as supernova remnants, pulsar wind nebulae, and binary systems. The upcoming Cherenkov Telescope Array (CTA) will be the first instrument to enable a survey of the entire Galactic plane in the energy range from a few tens of GeV to 300 TeV with unprecedented sensitivity and improved angular resolution. In this contribution we will revisit the scientific motivations for the survey, proposed as a Key ScienceProject for CTA. We will highlight recent progress, including improved physically-motivated models for Galactic source populations and interstellar emission, advance on the optimization of the survey strategy, and the development of pipelines to derive source catalogues tested on simulated data. Based on this, we will provide a new forecast on the properties of the sources thatCTA will detect and discuss the expected scientific return from the study of gamma-ray source populations.

description: We present a multivariate stochastic volatility model with leverage, which is flexible enough to recapture the individual dynamics as well as the interdependencies between several assets while still being highly analytically tractable. First we derive the characteristic function and give conditions that ensure its analyticity and absolute integrability in some open complex strip around zero. Therefore we can use Fourier methods to compute the prices of multi-asset options efficiently. To show the applicability of our results, we propose a concrete specification, the OU-Wishart model, where the dynamics of each individual asset coincide with the popular Gamma-OU BNS model. This model can be well calibrated to market prices, which we illustrate with an example using options on the exchange rates of some major currencies. Finally, we show that covariance swaps can also be priced in closed form.

title: Comparison of Land and Aquatic Loaded Countermovement Jump Landings in Female NCAA Division I Collegiate Athletes
Creators: name: Nielson, Samantha L
Publisher: name: Utah State University
Year: 2017

description: The purpose of this study was to investigate alterations in lower extremity kinematics during the landing phase of a countermovement jump when performed in different environments and under multiple external loads. Twenty-four NCAA Divison I collegiate female athletes performed 12 countermovement jumps on land and 12 jumps in water, submerged to the xiphoid process, for a total of 24 jumps. Within each environmental condition, four loading conditions of three jumps each were performed using a weighted vest: Unloaded, 10%, 20%, or 30% of body mass. The hip, knee, and ankle angles were measured as the smallest angles between the major body segments (trunk, thigh, shank, and foot) in the sagittal plane using the digital goniometer tool from Kinovea video analysis software at the point of maximum knee flexion. Larger angles indicated decreased joint flexion and smaller angles indicated increased joint flexion. The mean hip, knee, and ankle angles were significantly greater for the jump landings in water compared to on land, regardless of load (133.7° vs. 113.9°, 119.5° vs. 107.5°, and 91.7° vs. 85.6°, p < 0.001). Independent of environment, the loading conditions also affected the joint angles. The unloaded hip angles were significantly greater than the 10%, 20%, and 30% loaded angles (128.0° vs. 123.3°, 122.5°, and 121.6°, p < 0.001) and the unloaded ankle angle was significantly greater than the 10%, 20%, and 30% loaded angles (89.6° vs. 88.5°, 88.4°, and 88.0°, p = 0.015, p = 0.023, and p = 0.007). Increasing lower extremity joint flexion during jump landing may help minimize ACL injury. The decreases in joint flexion during the aquatic jump landings may have occurred due to the off-loading from the buoyancy characteristics of water, which may be less harmful compared to decreased joint flexion on land. The significant increases in joint flexion due to loading condition may provide evidence for use in athlete training programs to help decrease the probability of ACL injury.

description: In this paper we consider the next-to-next-to-leading order total cross section of Higgs boson pair production in the large top quark mass limit and compute four expansion terms in $1/m_t^2$. Good convergence is observed below the top quark threshold, which makes our results a valuable input for approximation methods which aim for next-to-next-to-leading order corrections over the whole kinematic range. We present details on various steps of our calculation; in particular, we provide results for three- and four-particle phase-space master integrals and describe in detail the evaluation of the collinear counterterms.

description: We present a quantitative comparison between software features of the defacto standard X-ray spectral analysis tool, XSPEC, and ISIS, the Interactive Spectral Interpretation System. Our emphasis is on customized analysis, with ISIS offered as a strong example of configurable software. While noting that XSPEC has been of immense value to astronomers, and that its scientific core is moderately extensible--most commonly via the inclusion of user contributed "local models"--we identify a series of limitations with its use beyond conventional spectral modeling. We argue that from the viewpoint of the astronomical user, the XSPEC internal structure presents a Black Box Problem, with many of its important features hidden from the top-level interface, thus discouraging user customization. Drawing from examples in custom modeling, numerical analysis, parallel computation, visualization, data management, and automated code generation, we show how a numerically scriptable, modular, and extensible analysis platform such as ISIS facilitates many forms of advanced astrophysical inquiry.

description: We describe an extension of the hadronic SU(3) non-linear sigma model to include quarks. As a result, we obtain an effective model which interpolates between hadronic and quark degrees of freedom. The new parameters and the potential for the Polyakov loop (used as the order parameter for deconfinement) are calibrated in order to fit lattice QCD data and reproduce the QCD phase diagram. Finally, the equation of state provided by the model, combined with gravity through the inclusion of general relativity, is used to make predictions for neutron stars.

description: Policy compliance detection is the task of ensuring that a scenario conforms to a policy (e.g. a claim is valid according to government rules or a post in an online platform conforms to community guidelines). This task has been previously instantiated as a form of textual entailment, which results in poor accuracy due to the complexity of the policies. In this paper we propose to address policy compliance detection via decomposing it into question answering, where questions check whether the conditions stated in the policy apply to the scenario, and an expression tree combines the answers to obtain the label. Despite the initial upfront annotation cost, we demonstrate that this approach results in better accuracy, especially in the cross-policy setup where the policies during testing are unseen in training. In addition, it allows us to use existing question answering models pre-trained on existing large datasets. Finally, it explicitly identifies the information missing from a scenario in case policy compliance cannot be determined. We conduct our experiments using a recent dataset consisting of government policies, which we augment with expert annotations and find that the cost of annotating question answering decomposition is largely offset by improved inter-annotator agreement and speed.

description: Inspired by work of Montgomery on Fourier series and Donoho-Strak in signal processing, we investigate two families of rearrangement inequalities for the Fourier transform. More precisely, we show that the $L^2$ behavior of a Fourier transform of a function over a small set is controlled by the $L^2$ behavior of the Fourier transform of its symmetric decreasing rearrangement. In the $L^1$ case, the same is true if we further assume that the function has a support of finite measure. As a byproduct, we also give a simple proof and an extension of a result of Lieb about the smoothness of a rearrangement. Finally, a straightforward application to solutions of the free Shrödinger equation is given.

description: •

The use of nature-based solutions in the promotion of the environmental citizenship.

•

Nature-based solutions as a valuable resource towards empowerment for action.

Purpose: The study aims to assess the implementation of an intervention program that combines nature-based solutions with an environmental citizenship pedagogical approach for pre-service teachers. The research questions revolve around the educational potentials and challenges of this intervention. To our knowledge, no previous studies resorted to this combination to organize courses for initial teacher training.

Design/methodology/approach: For this qualitative and interpretative case study, data was obtained through focus groups. 30 pre-service teachers of the Basic Education Course (training kindergarten and primary school teachers) in Portugal participated in the intervention. The transcripts of the focus groups’ content were subjected to categorical qualitative content analysis.

Findings: According to the participants, the implemented approach contributed to the development of a better understanding of the complexity of the environmental issues addressed, and of critical thinking skills. The pre-service teachers recognized the educational potential of nature-based solutions in the promotion of their environmental citizenship and activist competences and of the pedagogical knowledge necessary for its implementation.

description: Active galactic nucleus (AGN) disks may be important sites of binary black hole (BBH) mergers. Here we show via numerical experiments with the high-accuracy, high precision code {\tt SpaceHub} that broken symmetry in dynamical encounters in AGN disks can lead to an asymmetry between prograde and retrograde BBH mergers. The direction of the hardening asymmetry depends on the initial binary semi-major axis. An asymmetric distribution of mass-weighted projected spin $χ_{\rm eff}$ should therefore be expected in LIGO-Virgo detections of BBH mergers from AGN disks. This channel further predicts that negative $χ_{\rm eff}$ BBH mergers are most likely for massive binaries.

Prediction of residual stress due to early age behaviour of massive concrete structures: on site experiments and macroscopic modelling

description: Early age behaviour of concrete is based on complex multi-physical and multiscale phenomena. The predication of both cracking risk and residual stresses in hardened concrete structures is still a challenging task. We propose in this paper a practical method to characterize in the construction site the material parameters and to identify a macroscopic model from simple tests. We propose for instance to use a restrained shrinkage ring test to identify a basic early age creep model based on a simple ageing visco-elastic Kelvin model. The strain data obtained from this test can be treated through an early age finite element incremental procedure such that the fitting parameters of the creep law can be quickly identified. The others properties of concrete have been measured at different ages (elastic properties, hydration kinetics, and coefficient of thermal expansion). From the identified early age model, we computed the temperature rise and the stress development in a non reinforced concrete stress for nuclear waste. The good agreement between in-situ measurement and predicted behaviour allowed us to validate our approach.

description: Purpose: This article brings into debate young people’s meaning-making of climate justice in different geographic regions, and explores the roles of political, social, economic, and education actors in supporting youth’s climate agency in their communities.


Design/methodology/approach: After selecting two schools located in Northern Portugal – in countryside/rural and in coastal/urban contexts – we conducted two focus group discussions with young students (aged between 16 and 19) and sixteen interviews with local stakeholders (policy-makers, economic agents, activists, and scientists). We performed content analysis, using climate justice’s dimensions as analytical axes.


Findings: The data analysis reveals that young people do not feel heard in schools or in policy-making processes on climate. In contrast, adults unanimously recognize the importance of having more youth voices but fail to identify opportunities for youth participation in local climate policymaking. In addition to procedural and intergenerational dimensions, issues of recognitional and distributional climate injustice are identified by youngsters in their regions.

Children’s beliefs about inherited characteristics
Creators: name: Kargbo, Dennis Borboh
Publisher: name: University of British Columbia
Year: 2010

description: Thirty two children (6 to 13 years) of average ability from three schools in Vancouver were interviewed about their beliefs regarding the phenomenon of inheritance. The study was purely exploratory. No hypothesis was tested. The subjects were exposed to five tasks, comprising twelve pictures, one live plant specimen and twenty questions. The first three tasks were designed to find out whether the subjects could differentiate between environmentally induced deformities and inherited traits in living organisms. The last two tasks were designed to find out whether the subjects invoke probability thinking in predicting the outcome of an offspring's inherited traits or not. The data collected was analyzed using tabular techniques: (a) Frequency distribution table. (b) Question-Response table. The results indicate that a large proportion of the subjects from the various age groups had difficulties differentiating between environmental deformities and inherited traits. Since the difficulties and the successes with the three tasks investigating the problem were found in all the age groups, it was suggested that possibly the acquisition of this concept is not dependent on age but is rather a function of the subject's experiences. On the other hand, the development of the thinking related to the making of probabilistic predictions was believed to be developmental. Younger subjects (6 to 9 years) were rigid and predicted with certainty; whereas the older subjects (10 to 13 years) made very imprecise and tentative predictions about the outcome of the offspring. This finding and others which are reported in this study about children's thinking regarding the phenomenon of inheritance, should help the curriculum developer and the classroom teacher in deciding how best appropriate learning opportunities could be provided for children (average ability) of the age groups that were studied.
Teachers' perceptions of cultural capital: How do they influence the teaching of civic, social and political education?
Creators: name: O'Brien, Gearoid
Publisher: name: JSSE - Journal of Social Science Education
Year: 2023

description:  Highlights 

− Teachers of citizenship education in lower SES schools emphasise voting and elections in their teaching approach. 

− Teachers of citizenship education in fee-paying schools emphasise political structures, national politics and social responsibility. 

− Teachers of citizenship education in lower SES schools tend to emphasise personal responsibility. 

− Teachers of citizenship education in fee-paying schools tend to focus on participatory citizenship. 

− There is little evidence of justice-oriented citizenship education in Irish schools. 

Purpose: This study examines whether differences exist in the teaching of CSPE across school types: Delivering Equality of Opportunity in Schools (DEIS), fee-paying and ‘other’ schools. The study also examines whether such differences are linked to students’ cultural capital.

Design Methodology: A survey of 222 Irish CSPE teachers was used to identify differences in their teaching of CPSE. Responses were analysed by statistical and thematic analysis. The findings are discussed in relation to Bourdieu and Passeron’s work on cultural capital and Westheimer and Kahne’s typology of three forms of citizenship.

Findings: CSPE in DEIS schools was aligned with personally responsible citizenship, whereas CSPE in fee-paying schools tended to align with participatory citizenship. In other schools there were elements of both personally responsible and participatory citizenship.

Research limitations: The results are not generalisable. Furthermore, the findings are based on the teachers’ espoused practice rather than observation of their actual practice.

description: Applying halo models to analyze the small-scale clustering of galaxies is a proven method for characterizing the connection between galaxies and their host halos. Such works are often plagued by systematic errors or are limited to clustering statistics which can be predicted analytically. In this work, we employ a numerical mock-based modeling procedure to examine the clustering of SDSS DR7 galaxies. We apply a standard halo occupation distribution (HOD) model to dark-matter-only simulations with a LCDM cosmology. To constrain the theoretical models, we utilize a combination of galaxy number density and selected scales of the projected correlation function, redshift-space correlation function, group multiplicity function, average group velocity dispersion, mark correlation function, and counts-in-cells statistics. We design an algorithm to choose an optimal combination of measurements that yields tight and accurate constraints on our model parameters. Compared to previous work using fewer clustering statistics, we find significant improvement in the constraints on all parameters of our halo model for two different luminosity-threshold galaxy samples. Most interestingly, we obtain unprecedented high-precision constraints on the scatter in the relationship between galaxy luminosity and halo mass. However, our best-fit model results in significant tension (>4 sigma) for both samples, indicating the need to add second-order features to the standard HOD model. To guarantee the robustness of these results, we perform an extensive analysis of the systematic and statistical errors in our modeling procedure, including a first-of-its-kind study of the sensitivity of our constraints to changes in the halo mass function due to baryonic physics.

description: A one parameter family of retarded linear operators on scalar fields on causal sets is introduced. When the causal set is well-approximated by 4 dimensional Minkowski spacetime, the operators are Lorentz invariant but nonlocal, are parametrised by the scale of the nonlocality and approximate the continuum scalar D'Alembertian, $\Box$, when acting on fields that vary slowly on the nonlocality scale. The same operators can be applied to scalar fields on causal sets which are well-approximated by curved spacetimes in which case they approximate $\Box - {1/2}R$ where $R$ is the Ricci scalar curvature. This can used to define an approximately local action functional for causal sets.
