description: We present the first quantitative spectral analysis of blue supergiant stars in the nearby galaxy NGC 2403. Out of a sample of 47 targets observed with the LRIS spectrograph at the Keck I telescope we have extracted 16 B- and A-type supergiants for which we have data of sufficient quality to carry out a comparison with model spectra of evolved massive stars and infer the stellar parameters. The radial metallicity gradient of NGC 2403 that we derive has a slope of -0.14 (+/- 0.05) dex/r_e, and is in accordance with the analysis of H II region oxygen abundances. We present evidence that the stellar metallicities that we obtain in extragalactic systems in general agree with the nebular abundances based on the analysis of the auroral lines, over more than one order of magnitude in metallicity. Adopting the known relation between stellar parameters and intrinsic luminosity we find a distance modulus m-M = 27.38 +/- 0.08 mag. While this can be brought into agreement with Cepheid-based determinations, it is 0.14 mag short of the value measured from the tip of the red giant branch. We update the mass-metallicity relation secured from chemical abundance studies of stars in resolved star-forming galaxies.

Heterogeneity of Depressive and Anxious Symptoms in Early Childhood: Influence by Self-Regulation and Classroom Climate
Creators: Zatto, Brenna R
Publisher: name: University of Alberta Library
Year: 2023

Depressive and anxious symptoms can emerge as early as preschool, though heterogeneity in these early symptoms is unclear. Examination of whether variation in the patterns of change in depressive symptoms diverge from those of anxious symptoms can help to better identify concerning symptom experiences. Examination of heterogeneity can also aid in identifying developmental tasks and contextual experiences that differentiate between symptom experiences, including self-regulation and classroom climate. Self-regulation allows for management of emotion, cognition, and behavior, though young children may vary in these abilities. Such variability in self-regulation may differentiate between depressive and anxious symptom experiences. Climate of the preschool classroom, including interactional and organizational quality, may also differentiate between symptom experiences, as preschool is a prominent context for development. To examine heterogeneity in depressive and anxious symptoms, growth mixture modeling was first used. Second, latent profile analysis was used to determine profiles of self-regulation. Third, multinomial logistic regression was used to examine whether the self-regulation profiles and classroom climate domains (emotional support, organization, instructional support) discriminate between depressive and anxious symptoms trajectories. Participants were 443 children (47.9% girls, Mage = 4.08 years, SD = 0.35) assessed in the fall and spring of preschool and kindergarten. Depressive and anxious symptoms were assessed by teachers at each wave. In the fall of preschool, self-regulation was assessed by teachers, caregivers, trained observers, and behavioral assessment and classroom climate was assessed by trained observers. Multiple trajectories were identified for depressive (low with decelerated growth, 92.81%; moderate with accelerated growth, 7.19%) and anxious symptoms (low and stable, 84.40%; moderate and decreasing, 8.66%; low and increasing, 6.94%). Multiple self-regulation profiles were also identified (typically-regulated, 69.65%; behaviorally-overregulated, 20.84%; emotionally-dysregulated, 9.50%). Children in the emotionally-dysregulated and behaviorally-overregulated profiles were more likely to follow the moderate with accelerated growth depressive symptoms trajectory. Children in the emotionally-dysregulated profile and in more emotionally supportive and organized classrooms were more likely to follow the moderate and decreasing anxious symptoms trajectory. Children vulnerable to elevated depressive symptoms may benefit from prevention and intervention efforts related to emotional and behavioral aspects of self-regulation. Children experiencing elevated anxious symptoms at the start of preschool may benefit from efforts related to emotional self-regulation and emotional and organizational qualities of the classroom.

description: The Large High Altitude Air Shower Observatory has reported the detection of cosmic-ray sources in Milky Way that can accelerate particles up to PeV (= 10$^{15}$ eV) energies. These sources, so called ``PeVatrons'', are mostly unidentified. Several classes of sources, such as supernova remnants, pulsar wind nebula, or young stellar clusters can potentially be the counterparts of these PeVatrons. The aim of this work is to study a pulsar wind nebula interpretation of one of these PeVatrons, LHAASO J2226+6057, which has a relatively well covered multi-frequency spectrum. We have performed a leptonic, time-dependent modeling of the pulsar wind nebula (PWN) associated with PSR J2229+6114 considering a time-energy-dependent diffusion-loss equation. Injection, energy losses, as well as escape of particles were considered to balance the time-dependent lepton population. We have also included the dynamics of the PWN and the associated supernova remnant (SNR) and their interaction via the reverse shock to study the reverberation phase of the system. We have considered different values of braking index ($n$) and true age ($t_{age}$) for the fitting of the multi-wavelength (MWL) spectral energy distribution (SED) of LHAASO J2226+6057. The best-fit PWN model parameters and their 1$σ$ confidence intervals were evaluated. We have also demonstrated the impact of reverberation on the MWL SED with increasing time. Additionally, we have discussed the resultant large radius and low magnetic field associated with the PWN in question, as caveats for the possible physical connection of the pulsar as the origin of this high energy source.

description: Computational intensity and sequential nature of estimation techniques for Bayesian methods in statistics and machine learning, combined with their increasing applications for big data analytics, necessitate both the identification of potential opportunities to parallelize techniques such as MCMC sampling, and the development of general strategies for mapping such parallel algorithms to modern CPUs in order to elicit the performance up the compute-based and/or memory-based hardware limits. Two opportunities for Single-Instruction Multiple-Data (SIMD) parallelization of MCMC sampling for probabilistic graphical models are presented. In exchangeable models with many observations such as Bayesian Generalized Linear Models, child-node contributions to the conditional posterior of each node can be calculated concurrently. In undirected graphs with discrete nodes, concurrent sampling of conditionally-independent nodes can be transformed into a SIMD form. High-performance libraries with multi-threading and vectorization capabilities can be readily applied to such SIMD opportunities to gain decent speedup, while a series of high-level source-code and runtime modifications provide further performance boost by reducing parallelization overhead and increasing data locality for NUMA architectures. For big-data Bayesian GLM graphs, the end-result is a routine for evaluating the conditional posterior and its gradient vector that is 5 times faster than a naive implementation using (built-in) multi-threaded Intel MKL BLAS, and reaches within the striking distance of the memory-bandwidth-induced hardware limit. The proposed optimization strategies improve the scaling of performance with number of cores and width of vector units (applicable to many-core SIMD processors such as Intel Xeon Phi and GPUs), resulting in cost-effectiveness, energy efficiency, and higher speed on multi-core x86 processors.

description: Research on international students’ learning experiences pays much less attention to those studying semester and/or year-long programmes in a country that differs significantly from their home country with respect to culture and the education system. Adopting transformative learning theory as the theoretical framework, this paper explores the learning effectiveness of students on such programme in a Chinese and in a UK university. It analyses the narratives of 27 students in relation to their cognitive and behavioural activities and also their self-reflective and collaborative reflective activities. The findings indicate that these students only partially achieved transformative learning. The main reasons are: (1) the duration of this type of programme was not long enough to achieve a full transformation and (2) both host universities did not include reflection in the learning process properly. This paper makes a contribution to cross-border learning literature in the Chinese and the UK contexts.

description: With their self-tuned time-varying responses, waveform-selective metasurfaces embedded with nonlinear electronics have shown fascinating applications, including distinguishing different electromagnetic waves depending on the pulse width. However, thus far they have only been realized with a spatially homogeneous scattering profile. Here, by modeling a metasurface as time-varying admittance sheets, we provide an analytical calculation method to predict the metasurface time-domain responses. This allows derivation of design specifications in the form of equivalent sheet admittance, which is useful in synthesizing a metasurface with spatiotemporal control, such as to realize a metasurface with prescribed time-dependent diffraction characteristics. As an example, based on the proposed equivalent admittance sheet modeling, we synthesize a waveform-selective Fresnel zone plate with variable focal length depending on the incoming pulse width. The proposed synthesis method of pulse-width-dependent metasurfaces may be extended to designing metasurfaces with more complex spatiotemporal wave manipulation, benefiting applications such as sensing, wireless communications and signal processing.

description: (Abridged) In this work, we study the 2.8x2.6 deg2 region in the emblematic Rosette Nebula, centred at the young cluster NGC 2244, with the aim of constructing the most reliable candidate member list to date, determining various structural and kinematic parameters, and learning about the past and the future of the region. Starting from a catalogue containing optical to mid-infrared photometry, as well as positions and proper motions from Gaia EDR3, we apply the Probabilistic Random Forest algorithm and derive membership probability for each source. Based on the list of almost 3000 probable members, of which about a third are concentrated within the radius of 20' from the centre of NGC 2244, we identify various clustered sources and stellar concentrations, and estimate the average distance of 1489+-37 pc (entire region), 1440+-32 pc (NGC 2244) and 1525+-36 pc (NGC 2237). The masses, extinction, and ages are derived by SED fitting, and the internal dynamic is assessed via proper motions relative to the mean proper motion of NGC 2244. NGC 2244 is showing a clear expansion pattern, with an expansion velocity that increases with radius. Its IMF is well represented by two power laws (dN/dM\propto M^{-α}), with slopes α= 1.05+-0.02 for the mass range 0.2 - 1.5 MSun, and α= 2.3+-0.3 for the mass range 1.5 - 20 MSun, in agreement with other star forming regions. The mean age of the region is ~2 Myr. We find evidence for the difference in ages between NGC 2244 and the region associated with the molecular cloud, which appears slightly younger. The velocity dispersion of NGC 2244 is well above the virial velocity dispersion derived from the total mass (1000+-70 MSun) and half-mass radius (3.4+-0.2 pc). From the comparison to other clusters and to numerical simulations, we conclude that NGC 2244 may be unbound, and possibly even formed in a super-virial state.

description: The Yarkovsky-O'Keefe-Radzievskii-Paddack (YORP) effect is a net torque caused by solar radiation directly reflected and thermally re-emitted from the surface of small asteroids and is considered to be crucial in their dynamical evolution. By long-term photometric observations of selected near-Earth asteroids, it's hoped to enlarge asteroid samples with a detected YORP effect to facilitate the development of a theoretical framework. Archived light-curve data are collected and photometric observations are made for (1685) Toro and (85989) 1999 JD6, which enables measurement of their YORP effect by inverting the light curve to fit observations from a convex shape model. For (1685) Toro, a YORP acceleration $\upsilon=(3.2\pm0.3)\times10^{-9}\ \rm{rad\cdot d^{-2}}(1σ error)$ is updated, which is consistent with previous YORP detection based on different light-curve data; for (85989) 1999 JD6, it is determined that the sidereal period is $7.667749\pm 0.000009$ h, the rotation pole direction locates is at $λ=232\pm 2^{\circ},\ β= -59\pm 1^{\circ}$, the acceleration is detected to be $\upsilon = (2.4\pm0.3)\times10^{-8}\ \rm{rad\cdot d^{-2}}(1σ error)$ and in addition to obtaining an excellent agreement between the observations and model. YORP should produce both spin-up and spin-down cases. However, including (85989) 1999 JD6, the $\rm{d}ω/\rm{d}t$ values of eleven near-Earth asteroids are positive totally, which suggests that there is either a bias in the sample of YORP detections or a real feature needs to be explained.

description: We prove additivity violation of minimum output entropy of quantum channels by straightforward application of ε-net argument and Lévy's lemma. The additivity conjecture was disproved initially by Hastings. Later, a proof via asymptotic geometric analysis was presented by Aubrun, Szarek and Werner, which uses Dudley's bound on Gaussian process (or Dvoretzky's theorem with Schechtman's improvement). In this paper, we develop another proof along Dvoretzky's theorem in Milman's view showing additivity violation in broader regimes than the existing proofs. Importantly, Dvoretzky's theorem works well with norms to give strong statements but these techniques can be extended to functions which have norm-like structures - positive homogeneity and triangle inequality. Then, a connection between Hastings' method and ours is also discussed. Besides, we make some comments on relations between regularized minimum output entropy and classical capacity of quantum channels.

Program Optimization with Local Search
Creators: Abdollahi, Fatemeh
Publisher: name: University of Alberta Library
Year: 2023

Recent advancements in large language models and program synthesis have enabled the development of powerful programming assistance tools. These tools are designed to help the programmer while writing a program in an online setting. In this thesis we introduce a programming assistant that can optimize a compilable version of a program with respect to a comparable objective.

We propose a local search approach for improving programs written by humans using bottom-up search algorithms. We present Program Optimization with Locally Improving Search (POLIS), which exploits the structure of a program, defined by its lines, in order to split the optimization into small program synthesis tasks that can be solved by the existing synthesis algorithms. POLIS iterates over lines of the program, trying to improve a single line at a time, while keeping the other lines fixed. It continues to iterate until it is unable to improve the objective value of the program or runs out of time.

Our hypothesis is that humans are capable of thinking abstractly and at a high level but they sometimes miss some details of their program. Computer agents, on the other hand, can figure out the details of a program efficiently, whether it is to optimize numerical values in a program or synthesize programs for programming tasks that can be solved with short programs. We leverage this ability of program synthesis algorithms and use them to optimize each line of a program iteratively. Thus, we optimize the human-written program by optimizing each line of it.

We evaluated POLIS in a 27-person user study where the participants wrote programs for playing two single-agent games: Lunar Lander and Highway. In this study, participants were rewarded based on their programs’ score. Results demonstrate that while human programmers may be capable of writing effective high-level program structures, they often fail to optimize important details of the programs. POLIS substantially improved the quality of all programs evaluated while preserving the high- level structure the programmers designed. These results show that this approach could be used as a helpful programming assistant for problems with measurable and comparable objectives.

description: We report on the numerical and theoretical results of sub-THz and THz detection by a current-driven InGaAs/GaAs plasmonic Field-Effect Transistor (TeraFET). New equations are developed to account for the channel length dependence of the drain voltage and saturation current. Numerical simulation results demonstrate that the effect of drain bias current on the source-to-drain response voltage (dU) varies with the device channel length. In a long-channel TeraFET where plasmonic oscillations cannot reach the drain, dU is always positive and rises rapidly with increasing drain current. For a short device in which plasmonic oscillations reach the drain, the current-induced nonuniform electric field leads to a negative response, agreeing with previous observations. At negative dU, the amplitude of the small-signal voltage at the drain side becomes larger than that at the source side. Thus, the device effectively serves as a THz amplifier in this condition. Under the resonant mode, the negative response can be further amplified near the resonant peaks. A new expression of dU is proposed to account for this resonant effect. Based on those expressions, a current-driven TeraFET spectrometer is proposed. The ease of implementation and simplified calibration procedures make it competitive or superior compared with other TeraFET-based spectrometers.

description: We develop approximation methods in the hybrid quantization of the Gowdy model with linear polarization and a massless scalar field, for the case of three-torus spatial topology. The loop quantization of the homogeneous gravitational sector of the Gowdy model (according to the improved dynamics prescription) and the presence of inhomogeneities lead to a very complicated Hamiltonian constraint. Therefore, the extraction of physical results calls for the introduction of well justified approximations. We first show how to approximate the homogeneous part of the Hamiltonian constraint, corresponding to Bianchi I geometries, as if it described a Friedmann-Robertson-Walker (FRW) model corrected with anisotropies. This approximation is valid in the high-energy sector of the FRW geometry (concerning its contribution to the constraint) and for anisotropy profiles that are sufficiently smooth. In addition, for certain families of states associated to regimes of physical interest, with negligible effects of the anisotropies and small inhomogeneities, one can approximate the Hamiltonian constraint of the inhomogeneous system by that of an FRW geometry with a relatively simple matter content, and then obtain its solutions.

MooZi: A High-Performance Game-playing System that Plans with a Learned Model
Creators: Wang, Zeyi
Publisher: name: University of Alberta Library
Year: 2023

The intent of this thesis is to develop a high-performance open-source system that plans with a learned model and to understand the algorithm through extensive analysis. We formulate the problem of maximizing accumulated rewards in Markov Decision Processes, and we frame playing games as such problems. We develop the MooZi system to solve these problems. MooZi includes (1) a MuZero-based algorithm that plans with a learned model (2) a distributed architecture that trains and evaluates the algorithm efficiently, and (3) a collection of tools to visualize and understand the algorithm. We empirically show that MooZi outperforms PPO and AC in MinAtar environments. We also show that MooZi learns to play the two-players board game Breakthrough. We use our tools to analyze the learned model by visualizing search trees and learned representation. We make MooZi publicly available to accelerate future research.

Detection and quantification of chronic wasting disease prions
Creators: Ness, Anthony
Publisher: name: University of Alberta Library
Year: 2023

Chronic wasting disease (CWD), a neurodegenerative prion disease of cervids, is geographically spreading across North America and Northern Europe. Wild cervids are infected by CWD disproportionately by species and sex. The precise mechanisms and animal behaviours that contribute to the patterns in CWD prevalence are poorly understood. CWD prions are shed from preclinically and clinically infected animals in body fluids, excretions, and from carcasses. Shed

CWD prions contaminate the environment – providing a source for indirect disease transmission. Deer have a variety of skin scent glands used for social communication could be exposed to- or shed prions. Involvement of these skin glands was hypothesized to be involved in CWD transmission and was investigated. Cellular prion protein presence in six skin glands and two other exocrine gland-containing tissues of mule deer and white-tailed deer were surveyed and quantified. The presence of cellular prion protein expression within glandular structures suggests that the tissues may be capable of replicating infectious prions. Disease-associated CWD prions were identified within interdigital glands in the feet of mule deer. CWD prions were observed in or near glandular structures of the interdigital glands, as well as within soil found in the hoof of

an infected mule deer. The results suggest that prions may be secreted from the feet of infected deer. Cervid behaviours that could contribute to CWD transmission are reviewed. CWD prions entering the environment contaminate soils and surfaces for years. A method was developed to detect and quantify adsorbed prion inactivation by anti-prion compounds – with a focus on humic substances. Insights into the use of humic substances for the inactivation of prions is discussed.

A framework for generative design and drafting for the manufacture and assembly of windows
Creators: Abdel-Jaber, Omar
Publisher: name: University of Alberta Library
Year: 2023

The process to fabricate windows for buildings begins with information provided through a web-based tool (also known as a Configure Price Quote), which includes window specifications and geometric information. The fabrication of the windows in the production line consists of the fabrication of the frame, the installation of the glass, the installation of hardware to allow for the operation of the window, the installation of the sealing product, packaging, and shipping to the construction site. This research aims to develop a framework to aid the web-based configuration tool (i.e., Configure Price Quote) to enable the sales representative or client to order and customize windows and improve the flow of information from the Configure Price Quote to the assembly line. As such, the proposed framework aims to automate the design and facilitate the drafting generation for the assembly and fabrication of windows and their sub-components. The proposed framework builds on similar tools developed for the manufacture of other types of products to enable the identification of the material and hardware used to build a window and to assess the business and design rules associated with the type and geometric location of the needed hardware. The research described in this thesis was conducted in collaboration with one of the largest window manufacturers in Canada at their facility in Edmonton, Alberta. The findings of this research are that the proposed framework reduces non-value-added activities in the design phase and improves the flow of information, thereby enabling window manufacturers to provide customized products in an efficient manner. Another notable contribution of this research is its focus on automating the design and facilitating the drafting generation of windows to support assemble-to-order products.

description: Changes in farm size over the past four decades have been closely associated with changes in machinery size. But an expanding range of farm sizes, existence of important economies of scale in machine manufacture, and increasing per farm and per machine financial requirements create pressures to alter this relationship. Full ownership and use of machines on each farm could give way to expanded use of custom services. Data from recent censuses of agriculture and other secondary sources are summarized. They show that custom services are a significant item, but are minor in comparison to services provided by owned machines. Both other farmers and nonfarm custom operators are important providers of farm machinery custom services. Such services are most used in the North Central and Southern regions, and in cash grain and livestock farms. All sizes of farm both use and provide custom services, but economic class I farms have the largest amounts of both. A number of forces which may lead to expansion in custom operations are discussed. Potential supplies of custom machine services from three sources are noted: (1) farmer custom operators, (2) custom operators not engaged in farming who provide either use of individual machines or complete farming operations, and (3) machinery dealers or others who provide short-term rentals.

description: Turbulence is a dominant feature operating in gaseous flows across nearly all scales in astrophysical environments. Accordingly, accurately estimating the statistical properties of such flows is necessary for developing a comprehensive understanding of turbulence. We develop and employ a hierarchical Bayesian fitting method to estimate the parameters describing the scaling relationships of the velocity power spectra of supersonic turbulence. We demonstrate the accuracy and other advantages of this technique compared with ordinary linear regression methods. Using synthetic power spectra, we show that the Bayesian method provides accurate parameter and error estimates. Commonly used normal linear regression methods can provide estimates that fail to recover the underlying slopes, up to 70% of the instances, even when considering the 2std.dev. uncertainties. Additionally, we apply the Bayesian methods to analyse the statistical properties of compressible turbulence in 3D numerical simulations. We model driven, isothermal, turbulence with rms Mach numbers in the highly supersonic regime M~15. We study the influence of purely solenoidal (divergence-free) and purely compressive (curl-free) forcing on the scaling exponent of the power spectrum. In simulations with solenoidal forcing and 1024^3 resolution, our results indicate that there is no extended inertial range with a constant scaling exponent. The bottleneck effect results in a curved power spectrum at all wave numbers and is more pronounced in the transversal modes compared with the longitudinal modes. Therefore, this effect is stronger in stationary turbulent flows driven by solenoidal forcing compared to the compressive one. The longitudinal spectrum driven with compressive forcing is the only spectrum with constant scaling exponent z=-1.94 +- 0.01, corresponding to slightly shallower slopes than the Burger's prediction.

description: Weber uses the term ‘logical’ with striking frequency: as a typical attribute of what is ‘rational’, but also in the definition of legal arrangements, where the ‘legally relevant components’ that characterise a legal relationship are ordered in a ‘manner which is itself logically free from contradiction’. Logic or logically significant characteristics are all features of the theoretical and academic doctrine of law, which stands as a contrasting type to the artisanal-empirical doctrine of the law of practitioners (represented by Roman and English law respectively). In this way logic or what is logical is an important sign of the difference between these two fundamental types of legal doctrine. Above all, logic and the logical play an outstanding role in Weber’s definition of a legal ‘system’ in the sense of ‘an assembly of all the legal propositions established by analysis in such a way that, taken all together, they form a system of rules that is itself logically free from contradiction and seamless in principle’. In this definition of ‘system’ Weber makes use of the postulates of so-called conceptual jurisprudence, something that did not exist in fact, but which originally signified a deliberate caricature (or criticism) of the science of the Pandects, of which Georg Friedrich Puchta (1798-1846) stood as the representative. He was selected because Rudolf von Jhering had Puchta mainly in mind when he framed the polemical idea of conceptual jurisprudence. Puchta was also singled out because he spoke, inter alia, of a ‘genealogy of concepts’, which encouraged the ascription of systemic qualities to his system of private law. Yet Weber omitted to test Puchta’s ‘system’ according to his own ideal-typical criterion of a system that ‘logically free from contradiction’ and ‘seamless in principle’. This deficiency will be remedied here.

description: Solar flares, especially the M- and X-class flares, are often associated with coronal mass ejections (CMEs). They are the most important sources of space weather effects, that can severely impact the near-Earth environment. Thus it is essential to forecast flares (especially the M-and X-class ones) to mitigate their destructive and hazardous consequences. Here, we introduce several statistical and Machine Learning approaches to the prediction of the AR's Flare Index (FI) that quantifies the flare productivity of an AR by taking into account the numbers of different class flares within a certain time interval. Specifically, our sample includes 563 ARs appeared on solar disk from May 2010 to Dec 2017. The 25 magnetic parameters, provided by the Space-weather HMI Active Region Patches (SHARP) from Helioseismic and Magnetic Imager (HMI) on board the Solar Dynamics Observatory (SDO), characterize coronal magnetic energy stored in ARs by proxy and are used as the predictors. We investigate the relationship between these SHARP parameters and the FI of ARs with a machine-learning algorithm (spline regression) and the resampling method (Synthetic Minority Over-Sampling Technique for Regression with Gaussian Noise, short by SMOGN). Based on the established relationship, we are able to predict the value of FIs for a given AR within the next 1-day period. Compared with other 4 popular machine learning algorithms, our methods improve the accuracy of FI prediction, especially for large FI. In addition, we sort the importance of SHARP parameters by Borda Count method calculated from the ranks that are rendered by 9 different machine learning methods.

description: Magnetic nanoparticles (MNP) can be used as drug carriers in novel cancer treatment approaches such as magnetic drug targeting (MDT). Computer simulations of MNP in a tumor vessel network under the influence of a magnetic field considering the physical and chemical properties of MNP were established before, however, an experimental validation of these simulations for specific settings is missing. The parameters influencing the targeting effectivity such as MNP concentration, blood flow velocities and different distances of the tumor vessel network to the magnet configuration were varied and a quantitative assessment of the targeting effectivity was performed photometrically determining the resulting iron concentration. Magnetic particle imaging (MPI) was used to analyze the correlation between MPI intensity values and the iron concentration. The parameter study confirmed the previous simulation results for the fixed magnet configuration.

description: We calculate the one-loop quantum corrections in the cubic Galileon theory, using cutoff regularization. We confirm the expected form of the one-loop effective action and that the couplings of the Galileon theory do not get renormalized. However, new terms, not included in the tree-level action, are induced by quantum corrections. We also consider the one-loop corrections in an effective brane theory, which belongs to the Horndeski or generalized Galileon class. We find that new terms are generated by quantum corrections, while the tree-level couplings are also renormalized. We conclude that the structure of the generalized Galileon theories is altered by quantum corrections more radically than that of the Galileon theory.

description: In this work we make use of available Integral Field Unit (IFU) spectroscopy and slit spectra of several nearby galaxies. The pre-existing empirical R and S calibrations for abundance determinations are constructed using a sample of HII regions with high quality slit spectra. In this paper, we test the applicability of those calibrations to the IFU spectra. We estimate the calibration-based abundances obtained using both the IFU and the slit spectroscopy for eight nearby galaxies. The median values of the slit and IFU spectra-based abundances in bins of 0.1 in fractional radius Rg (normalized to the optical radius) of a galaxy are determined and compared. We find that the IFU and the slit spectra-based abundances obtained through the R calibration are close to each other, the mean value of the differences of abundances is 0.005 dex and the scatter in the differences is 0.037 dex for 38 datapoints. The S calibration can produce systematically underestimated values of the IFU spectra-based abundances at high metallicities, the mean value of the differences is -0.059 dex for 21 datapoints, while at lower metallicities the mean value of the differences is -0.018 dex and the scatter is 0.045 dex for 36 data points. This evidences that the R calibration produces more consistent abundance estimations between the slit and the IFU spectra than the S calibration. We find that the same calibration can produce close estimations of the abundances using IFU spectra obtained with different spatial resolution and different spatial samplings. This is in line with the recent finding that the contribution of the diffuse ionized gas to the large aperture spectra of HII regions has a secondary effect.
