description: In this paper, different approaches to dealing with nuisance parameters in likelihood based inference are presented and illustrated by reference to the linear regression model with nonspherical errors. The estimator of the error variance using each of the approaches is also derived for the linear regression model with spherical errors. We observe that many of these estimators are unbiased. A theoretical comparison of the likelihood functions is reported and we note that some of them are equivalent. Empirical evidence in the literature indicates that estimators based on the conditional profile likelihood and tests based on the marginal likelihood have better small sample properties compared to those based on other likelihood and message length functions.

description: Consider a surface described by a Hamiltonian which depends only on the metric and extrinsic curvature induced on the surface. The metric and the curvature, along with the basis vectors which connect them to the embedding functions defining the surface, are introduced as auxiliary variables by adding appropriate constraints, all of them quadratic. The response of the Hamiltonian to a deformation in each of the variables is examined and the relationship between the multipliers implementing the constraints and the conserved stress tensor of the theory established.

description: The presence of nuisance parameters causes unexpected complications in econometric inference procedures. A number of modified likelihood and message length functions have been developed for better handling of nuisance parameters but all of them are not equally efficient. In this paper, we empirically compare different modified likelihood and message length functions in the context of estimation and testing of parameters from linear regression disturbances that follow either a first-order moving average or first-order autoregressive error processes. The results show that estimators based on the conditional profile likelihood and tests based on the marginal likelihood are best. If there is a minor identification problem, the sizes of the likelihood ratio and Wald tests based on simple message length functions are best. The true sizes of the Lagrange multiplier tests based on message length functions are rather poor because the score functions of message length functions are biased.

description: In the paper arXiv:2002.12065, the authors developed a new method to compute the exact overlap formulas between integrable boundary states and on-shell Bethe states in integrable spin chains. This method utilizes the coordinate Bethe ansatz representation of wave functions and singularity property of the off-shell overlaps. In this paper, we use this new method to derive the formula for overlaps between the Lieb-Liniger Bethe states and the Bose-Einstein condensate (BEC) state. As a simple application this method, we obtained the overlaps between the Lieb-Liniger eigenstates and the free particle states with pair structure.

description: We employ the Keldysh formalism in the quasiclassical approximation to study transport in a diffusive superconductor. The resulting 4x4 transport equations describe the flow of charge and energy as well as the corresponding flow of spin and spin energy. Spin-flip scattering due to magnetic impurities is included. We find that the spin-flip length is renormalized in the superconducting case and propose an experimental system to measure the spin-accumulation in a superconductor.

description: This study investigates linear and nonlinear effects of job tenure on organizational performance and explores how administrators’ job tenure can moderate the relationship between three key managerial strategies—innovative management, participatory management, and external management—and performance. Using archival performance indicators available from the Centers for Medicare and Medicaid Services in combination with a recent survey of nursing home administrators, we find that job tenure has a linear and nonlinear relationship with two different performance dimensions, respectively. Also, more experienced managers are better able to manage external environments and share power internally to achieve better outcomes.
An investigation into the Pharmaceutical Sciences Media Wall

description: The purpose of this investigation was to research alternative technologies that can be used as a replacement for the current Pharmaceutical Sciences Media Wall. The Media Wall is part of the exhibit, “The Story Medicines”, in the UBC Pharmacy building and is used to display pharmaceutical information. There are four main problems associated with the current media wall. There is high maintenance costs associated with bulb replacements each year. The spacing of the rear throw projectors causes an uneven light distribution which creates large shadows on the screen. The projectors consume a large amount of power to operate and due the software being proprietary; there are problems with updating software and flexibility in displaying content. A preliminary analysis was performed on four different technologies, one of being the current setup. This includes projectors, LCD, LED, and MicroTile screens; it was found that MicroTiles would be the most reasonable in the long run due to its low maintenance costs. It also provides flexibility in the design of a media wall. After performing a triple bottom line analysis, the effects of MicroTiles on a social aspect was mostly beneficial as it would solve the issues regarding the shadows in between screens and the use of proprietary software. On the other hand, MicroTiles were not the best economic choice due to the very expensive capital cost. Savings could only be made from the reduced maintenance cost. MicroTiles were the environmental choice as they do not include materials such as mercury, phosphorus, or toxic coolants; thus; they comply with the Restriction of Hazardous Substances (RoHS) Directive. MicroTiles consist of a solid metal housing and removable internal components that are 80% recyclable and 90% recoverable. After evaluating the triple bottom line, Christie MicroTile is recommended for use.

Publisher: name: American University
Year: 2023

description: Examples of complex-valued random phenomena in science and engineering are abound, and joint blind source separation (JBSS) provides an effective way to analyze multiset data. Thus there is a need for flexible JBSS algorithms for efficient data-driven feature extraction in the complex domain. Independent vector analysis (IVA) is a prominent recent extension of independent component analysis to multivariate sources, i.e., to perform JBSS, but its effectiveness is determined by how well the source models used match the true latent distributions and the optimization algorithm employed. The complex multivariate generalized Gaussian distribution (CMGGD) is a simple, yet effective parameterized family of distributions that account for full second- and higher-order statistics including noncircularity, a property that has been often omitted for convenience. In this paper, we marry IVA and CMGGD to derive, IVA-CMGGD, with a number of numerical optimization implementations including steepest descent, the quasi-Newton method Broyden–Fletcher–Goldfarb–Shanno (BFGS), and its limited-memory sibling limited-memory BFGS all in the complex-domain. We demonstrate the performance of our algorithm on simulated data as well as a 14-subject real-world complex-valued functional magnetic resonance imaging dataset against a number of competing algorithms.

description: This papers presents a method for simultaneously estimating a system of nonparametric multiple regressions which may seem unrelated, but where the errors are potentially correlated between equations. We show that the prime advantage of estimating such a 'seemingly unrelated' system of nonparametric regressions is that substantially less observations can be required to obtain reliable function estimates than if each of the regression equations was estimated separately and the correlation ignored. This increase in efficiency is investigated empirically using both simulated and real data. The method suggested here develops a Bayesian hierarchical framework where the regression function is represented as a linear combination of a large number of basis terms, the number of which is typically greater than the sample size. All the regression coefficients, and the variance matrix of the errors, are estimated simultaneously using their posterior means. The computation is carried out using a Markov chain Monte Carlo sampling scheme that employs a 'focused sampling' step to combat the high dimensional representation of the function and a Metropolis-Hastings step to correctly account for the distribution of the covariance matrix. The methodology is also easily extended to other nonparametric multivariate regression models.

description: We present the escape fraction of hydrogen ionizing photons (f_esc) from a sample of 34 high-resolution cosmological zoom-in simulations of galaxies at z>5 in the Feedback in Realistic Environments project, post-processed with a Monte Carlo radiative transfer code for ionizing radiation. Our sample consists of 8500 halos in M_vir~10^8--10^{12} M_sun (M_star~10^4--10^{10} M_sun) at z=5--12. We find the sample average increases with halo mass for M_vir~10^8--10^{9.5} M_sun, becomes nearly constant for M_vir~10^{9.5}--10^{11} M_sun, and decreases at M_vir>10^{11} M_sun. Equivalently, increases with stellar mass up to M_star~10^8 M_sun and decreases at higher masses. Even applying single-star stellar population synthesis models, we find a moderate ~0.2 for galaxies at M_star~10^8 M_sun. Nearly half of the escaped ionizing photons come from stars 1--3 Myr old and the rest from stars 3--10 Myr old. Binaries only have a modest effect, boosting by ~25--35% and the number of escaped photons by 60--80%. Most leaked ionizing photons are from vigorously star-forming regions that usually contain a feedback-driven kpc-scale superbubble surrounded by a dense shell. The shell is forming stars while accelerated, so new stars formed earlier in the shell are already inside the shell. Young stars in the bubble and near the edge of the shell can fully ionize some low-column-density paths pre-cleared by feedback, allowing a large fraction of their ionizing photons to escape. The decrease of at the high-mass end is due to dust attenuation, while at the low-mass end, decreases owing to inefficient star formation (and hence feedback). At fixed mass, tends to increase with redshift. Our simulations produce sufficient ionizing photons for cosmic reionization.

Marketing inclusion : A social justice project for diversity education
Creators: name: Grier, Sonya
Publisher: name: American University
Year: 2023

description: Challenges related to marketplace diversity present an opportunity to prepare students to successfully engage with diversity through innovative curricular approaches. The present research develops a semester-long course project designed to enhance students’ awareness and understanding of diversity and inclusion issues from a social justice perspective. We discuss the context of diversity issues in business schools and identify key issues affecting marketing educators. Our review of the pedagogical literature on diversity highlights the importance of a social justice orientation. Social cognitive theory is used as a conceptual framework to guide the design of a problem-based experiential project. We detail project implementation and assess evidence regarding the impact of the project. Findings suggest an experiential, problem-based class project can support students understanding of diversity from a social justice perspective. We discuss the project benefits and challenges and highlight pedagogical issues for educators who want to integrate diversity content into a broad array of marketing courses.

The ratio of cADPR/NAD+ levels in cultured CD1 wild-type DRG neurons (i.e. expressing endogenous SARM1) infected with human SARM1 constructs carrying rare variants identified in ALS patients. The variants are significantly more active than the reference human SARM1 allele in the presence of endogenous SARM1. This activity is dependent on the activity of the SARM1 mutant, as demonstrated by the loss of activity when a second activity-abolishing mutation, E642A, is introduced into the construct. Data are expressed relative to cADPR/NAD+ in reference SARM1-expressing neurons.

description: The Konishi anomalies for noncommutative N=1 supersymmetric U(1) gauge theory arising from planar and nonplanar diagrams are calculated. Whereas planar Konishi anomaly is the expected \star-deformation of the commutative anomaly, nonplanar anomaly reflects the important features of nonplanar diagrams of noncommutative gauge theories, such as UV/IR mixing and the appearance of nonlocal open Wilson lines. We use the planar and nonplanar Konishi anomalies to calculate the effective superpotential of the theory. In the limit of vanishing |Θp|, with Θthe noncommutativity parameter, the noncommutative effective superpotential depends on a gauge invariant superfield, which includes supersymmetric Wilson lines, and has nontrivial dependence on the gauge field supermultiplet.

description: Brain-Computer Interfaces (BCI) based on Electroencephalography (EEG) signals, in particular motor imagery (MI) data have received a lot of attention and show the potential towards the design of key technologies both in healthcare and other industries. MI data is generated when a subject imagines movement of limbs and can be used to aid rehabilitation as well as in autonomous driving scenarios. Thus, classification of MI signals is vital for EEG-based BCI systems. Recently, MI EEG classification techniques using deep learning have shown improved performance over conventional techniques. However, due to inter-subject variability, the scarcity of unseen subject data, and low signal-to-noise ratio, extracting robust features and improving accuracy is still challenging. In this context, we propose a novel two-way few shot network that is able to efficiently learn how to learn representative features of unseen subject categories and how to classify them with limited MI EEG data. The pipeline includes an embedding module that learns feature representations from a set of samples, an attention mechanism for key signal feature discovery, and a relation module for final classification based on relation scores between a support set and a query signal. In addition to the unified learning of feature similarity and a few shot classifier, our method leads to emphasize informative features in support data relevant to the query data, which generalizes better on unseen subjects. For evaluation, we used the BCI competition IV 2b dataset and achieved an 9.3% accuracy improvement in the 20-shot classification task with state-of-the-art performance. Experimental results demonstrate the effectiveness of employing attention and the overall generality of our method.

description: This paper shows that two-stage technologies can provide a general procedure for combining profit and value-added functions to obtain new specifications of import demand and output supply systems. In such technologies, we assume that imports interact with other exogenous variables to produce intermediate inputs, which are in turn used to produce final outputs. To show the utility of this new approach, we use it to specify and estimate the Australian GNP function. As will be seen, our proposed framework has an attractive property: the capability of incorporating exogenous effects such as labour and capital endowments within a strong theoretical underpinning. We investigate a new GNP function for which the demand and supply systems are effectively globally regular. Our results demonstrate that the new approach is feasible and promising while the estimated elasticities are not significantly different from those of the traditional models.

The results of SER for FI CCDs are compared with those obtained from SER techniques applied to BI CCD event data. Both simulated data and Chandra/ACIS observations of the Orion Nebular Cluster were used to test and evaluate the achievement of the various SER techniques.

description: This paper presents an SIR epidemic model with two different types of perturbations: white and Lévy noises. We consecrate to develop a mathematical method to obtain the asymptotic properties of the perturbed model. We use the comparison theorem, mutually exclusive possibilities lemma, and some new techniques of the stochastic differential systems to discuss the following characteristics: persistence in the mean, ergodicity, and extinction of the disease. Finally, numerical simulations about different perturbations are realized to confirm the obtained theoretical results.

title: ADHD as an Evolutionary Mismatch

description: Attention Deficit Hyperactivity Disorder, ADHD, is currently classified as a mental disorder in the DSM-V. The classification of a mental disorder leads to significant issues such as over-reliance on prescription medications, removal of agency, negative self-valuation, and more. Recent data in areas such as genetics, neurobiology, and psychology support the hypothesis that ADHD may be better understood as an evolutionary adaptive process that became maladaptive as a result of substantially different environmental characteristics in the modern environment. Key symptoms of ADHD may be explained by two processes. The first process is due to a genetic variation in Dopamine Receptor D4 that may have contributed to symptoms that aided nomadic humans in migrating out of Africa. The second process may be explained by the sympathetic nervous system’s suppression of the prefrontal cortex in the presence of chronic stress which led to behaviors useful for immediate survival in the context of the ancestral environment. The Evolutionary Mismatch Model of ADHD may help inform alternative interventions that can minimize the negative effects of ADHD seen in the modern environment. Alternative interventions include daily exercise, dietary supplementation of Omega 3/6 fatty acids, and increased vitamin D exposure through exposure to sunlight or dietary supplementation.

description: The Glauber dynamics is studied in a single-chain magnet. As predicted, a single relaxation mode of the magnetization is found. Above 2.7 K, the thermally activated relaxation time is mainly governed by the effect of magnetic correlations and the energy barrier experienced by each magnetic unit. This result is in perfect agreement with independent thermodynamical measurements. Below 2.7 K, a crossover towards a relaxation regime is observed that is interpreted as the manifestation of finite-size effects. The temperature dependences of the relaxation time and of the magnetic susceptibility reveal the importance of the boundary conditions.

description: We present a novel treatment for calculating the in-medium quark condensates. The advantage of this approach is that one does not need to make further assumptions on the derivatives of model parameters with respect to the quark current mass. The normally accepted model-independent result in nuclear matter is naturally reproduced. The change of the quark condensate induced by interactions depends on the incompressibility of nuclear matter. When it is greater than 260 MeV, the density at which the condensate vanishes is higher than that from the linear extrapolation. For the chiral condensate in quark matter, a similar model-independent linear behavior is found at lower densities, which means that the decreasing speed of the condensate in quark matter is merely half of that in nuclear matter if the pion-nucleon sigma commutator is six times the average current mass of u and d quarks. The modification due to QCD-like interactions is found to slow the decreasing speed of the condensate, compared with the linear extrapolation.

title: Modelling of solar magnetic fields using cellular automata models
Creators: name: Brockwell, Christopher Peter
Publisher: name: The Open University

description: Solar activity, including flares, CMEs, sunspots, global fleld reversal and, consequential to these, particle acceleration and X-ray emission result from the complexity of the atmospheric magnetic fields. These fields are driven into complex topologies by the continual stochastic photospheric motions and granulation flows. Significant energy is stored in the magnetic field however magnetic reconnection provides a mechanism for the relaxation and simplification of the field and release of this energy. Reconnection is capable of providing the observed plasma heating, field reorganisation and particle acceleration, although the relationship between reconnection and flaring is not yet understood. It is clear however that the field topology is key. Given fiare-size self-similarity, the short time-scales of hard X-ray emission and the observed apparent self-organisation, flaring models (Lu & Hamilton 1991) have been constructed based upon self-organised criticality (‘SOC’) with minimal physics and have produced plausible fiare-size distributions. The model by MacKinnon, Macpherson & Vlahos (1996) however assumed only local flare-triggering and made no statements regarding flare physics. This model reproduced the broad statistical features of flares yet without any implicit SOC.
We speculate that the observed Solar activity arises from the self-interaction of the magnetic field, flux emergence/submergence and reconnection without the necessity for invoking SOC or power-law distributed convective flows. Our first model was a simple 1-D cellular automata (‘CA’) containing only formalised field connectivity, reconnection and flux emergence/submergence. The model produced self-similarity in fiare-sizes over four orders of magnitude. The following model built upon the first and included more realistic physics with continuous parameter values. The model gave power- law distributions in field density and fiare-sizes (up to seven orders of magnitude) without inclusion of SOC or power-law forcing. The results were robust and insensitive to details of the reconnection mechanism. We derive analytical explanations for the observed rapid decay curves of impulsive-phase X-ray emission and consider that the flares produced represent presently unresolvable reconnection events. It was found that, similar to large Solar flares, large events are rarely concurrent.

description: We have analyzed new, archival and published high resolution radio and X-ray observations of a sample of composite LINER/HII galaxies known to exhibit AGN-like properties. Five of the 16 AGN candidates have milliarcsecond-scale detections and are found to display a compact, flat spectrum, high brightness temperature radio core, four of which also exhibit extended radio emission. Five of the eight AGN candidates with available high resolution X-ray observations were found to possess a hard X-ray nuclear source, two of which have no milliarcsecond radio detection. The combined high resolution radio and X-ray data yield a 50% detection rate of low luminosity AGN among the AGN candidates, which translates into a 12% detection rate for the entire composite LINER/HII sample. In the sources where the AGN has been unambiguously detected, the ionizing power of the AGN is not sufficient to generate the observed emission lines, unless the hard X-rays are heavily obscured. We attempt to apply a canonical advection-dominated accretion flow (ADAF) and jet model to the sample sources in order to explain the observed radio and X-ray emission. While ADAFs may be responsible for the observed emission in submillijansky radio cores like NGC 7331, they do not appear consistent with the radio emission observed in the milliarcsecond-scale radio detected cores; the latter sources are more likely to have an energetically important contribution from a radio-emitting jet.
