description: Large redshift surveys capable of measuring the Baryon Acoustic Oscillation (BAO) signal have proven to be an effective way of measuring the distance-redshift relation in cosmology. Building off the work in Zhu et al. (2015), we develop a technique to directly constrain the distance-redshift relation from BAO measurements without splitting the sample into redshift bins. We parametrize the distance-redshift relation, relative to a fiducial model, as a quadratic expansion. We measure its coefficients and reconstruct the distance-redshift relation from the expansion. We apply the redshift weighting technique in Zhu et al. (2015) to the clustering of galaxies from 1000 QuickPM (QPM) mock simulations after reconstruction and achieve a 0.75% measurement of the angular diameter distance $D_A$ at $z=0.64$ and the same precision for Hubble parameter H at $z=0.29$. These QPM mock catalogs are designed to mimic the clustering and noise level of the Baryon Oscillation Spectroscopic Survey (BOSS) Data Release 12 (DR12). We compress the correlation functions in the redshift direction onto a set of weighted correlation functions. These estimators give unbiased $D_A$ and $H$ measurements at all redshifts within the range of the combined sample. We demonstrate the effectiveness of redshift weighting in improving the distance and Hubble parameter estimates. Instead of measuring at a single 'effective' redshift as in traditional analyses, we report our $D_A$ and $H$ measurements at all redshifts. The measured fractional error of $D_A$ ranges from 1.53% at $z=0.2$ to 0.75% at $z=0.64$. The fractional error of $H$ ranges from 0.75% at $z=0.29$ to 2.45% at $z = 0.7$. Our measurements are consistent with a Fisher forecast to within 10% to 20% depending on the pivot redshift. We further show the results are robust against the choice of fiducial cosmologies, galaxy bias models, and RSD streaming parameters.

description: The "separant" of the evolution equation u_t=F, where F is some differentiable function of the derivatives of u up to order m is the partial derivative \partial F}/{\partial u_m} where u_m={\partial^m u}/{\partial x}^m. We apply the formal symmetry method proposed in [MSS (1991)] to the classification of scalar evolution equations of orders m\le 15, with non-trivial ρ^{(-1)}=\left[\partial F/\partial u_m\right]^{-1/m} and rho^{(1). We obtain the "top level" parts of these equations and their "top dependencies" with respect to the "level grading" defined in [Mizrahi, Bilge (2013)]. We show that if rho^{(-1)} depends on u,u_1,\dots,u_b, where b is the base level, then, these equations are level homogeneous polynomials in u_{b+i},\dots ,u_m, i\ge 1 and the coefficient functions are determined up to their dependencies on u,u_1,\dots,u_{b-1}. We prove that if ρ^{(3)} is non-trivial, then ρ^{(-1)}=(αu_b^2+βu_b+γ)^{1/2}, with b\le 3 while if ρ^{(3)} is trivial, then rho^{(-1)}=(λu_b+μ)^{1/3}, where b\le 5 and alpha, beta, gamma, lambda and mu are functions of u,\dots,u_{b-1}. We show that these equations form commuting flows and we construct their recursion operators that are respectively of orders 2 and 6 for non-trivial and trivial rho^(3) respectively. Omitting lower order dependencies, we show that equations with non-trivial rho^(3) and b=3 are symmetries of the "essentially non-linear third order equation". For trivial rho^(3), the equations with b=5 are symmetries of a non-quasilinear fifth order equation obtained in [Bilge,(2005)] while for b=3,4 they are symmetries of quasilinear fifth order equations and we outline the transformations to polynomial equations where $u$ has zero scaling weight, suggesting that the hierarchies that we obtain could be transformable to known equations possibly by introducing non-locality.

description: This article presents a Mortgage-Backed Security (MBS) model. Our analysis has focused on the model’s theoretical underpinnings and its implementation. We have found that the theoretical assumptions with respect to the prepayment model are suitable for trading purposes. We begin with a review of mortgage mathematics and outlines variables that are used in subsequent sections. Payment schedules of mortgages and the cashflows accruing to an MBS holder are also discussed in this section. A discounted cash flow (DCF) model constitutes the main pricing engine of the MBS, however, the main theoretical aspects of the model pertain to the prepayment assumptions corresponding to the underlying mortgage. A discussion of the two prepayment models is outlined in the next section.

description: Many computer vision problems can be posed as learning a low-dimensional subspace from high dimensional data. The low rank matrix factorization (LRMF) represents a commonly utilized subspace learning strategy. Most of the current LRMF techniques are constructed on the optimization problems using L1-norm and L2-norm losses, which mainly deal with Laplacian and Gaussian noises, respectively. To make LRMF capable of adapting more complex noise, this paper proposes a new LRMF model by assuming noise as Mixture of Exponential Power (MoEP) distributions and proposes a penalized MoEP (PMoEP) model by combining the penalized likelihood method with MoEP distributions. Such setting facilitates the learned LRMF model capable of automatically fitting the real noise through MoEP distributions. Each component in this mixture is adapted from a series of preliminary super- or sub-Gaussian candidates. Moreover, by facilitating the local continuity of noise components, we embed Markov random field into the PMoEP model and further propose the advanced PMoEP-MRF model. An Expectation Maximization (EM) algorithm and a variational EM (VEM) algorithm are also designed to infer the parameters involved in the proposed PMoEP and the PMoEP-MRF model, respectively. The superseniority of our methods is demonstrated by extensive experiments on synthetic data, face modeling, hyperspectral image restoration and background subtraction.

description: The paper revisits the Bayesian group lasso and uses spike and slab priors for group variable selection. In the process, the connection of our model with penalized regression is demonstrated, and the role of posterior median for thresholding is pointed out. We show that the posterior median estimator has the oracle property for group variable selection and estimation under orthogonal designs, while the group lasso has suboptimal asymptotic estimation rate when variable selection consistency is achieved. Next we consider bi-level selection problem and propose the Bayesian sparse group selection again with spike and slab priors to select variables both at the group level and also within a group. We demonstrate via simulation that the posterior median estimator of our spike and slab models has excellent performance for both variable selection and estimation.

description: We investigate the zero-temperature ferromagnetic behavior of a two-component repulsive Fermi gas in the presence of a correlated random field that represents an optical speckle pattern. The density is tuned so that the (noninteracting) Fermi energy is close to the mobility edge of the Anderson localization transition. We employ quantum Monte Carlo simulations to determine various ground-state properties, including the equation of state, the magnetic susceptibility, and the energy of an impurity immersed in a polarized Fermi gas (repulsive polaron). In the weakly interacting limit, the magnetic susceptibility is found to be suppressed by disorder. However, it rapidly increases with the interaction strength, and it diverges at a much weaker interaction strength compared to the clean gas. Both the transition from the paramagnetic phase to the partially ferromagnetic phase, and the one from the partially to the fully ferromagnetic phase are strongly favored by disorder, indicating a case of order induced by disorder.

DESIGN AND IMPLEMENT MINT-708 CONFIGURATION AND TROUBLESHOOT EXAM IN EVE-NG AND AUTOMATE MARKING
Creators: Shahnawaz Mir
Publisher: name: University of Alberta Library
Year: 2023

Exam paper marking has always been time-consuming and takes a lot of work. By automating the marking of structured-type questions, we hope to solve this problem. A web-based system has been created to gather answers, mark them, and give students feedback. The final course grades that lecturers give out are meant to reflect each student's degree of accomplishment.

Numerous judgments are based on these grades. An adequate amount of accuracy and efficiency is needed in the marking and grading process to ensure the grades are likely to convey accurate information and mislead the decision-maker. Exam script marking is laborious, especially when

done manually and with many pupils. It takes a long time and is prone to mistakes. However, using a computer and the appropriate software package makes the process simpler and more accurate. Finding a means to carry out this marking process that is both quick and accurate enough is a complex but intriguing topic. An electronic marking script is created in this work. The program is developed in Python and is run on a Linux-based server. The designed program operated efficiently and delivers the desired outcomes when finished. It enables automatic exam marking and score grading based on student responses that match the right ones that had been added to the system's data collection. A computer-based automated marking system

automatically grades tests, assignments, and other sorts of assessments. Algorithms and statistical models evaluate student responses and provide grades or comments.

The approach can aid in lessening instructors' workloads and improving the effectiveness of the grading process. It will enable the teacher to grade the exam using the students' configuration. In contrast to conventional marking, it can be carried out using a local program or a browser-based application sent over the Internet, in our case, using a Linux machine and browser.

The MINT-708 exam is based on the EVE-NG server, a multi-vendor graphical network emulation server that allows us to build network topologies for testing and development quickly. MINT-708 involves configuring multi-vendor network devices like Juniper, Cisco, Alcatel, etc., physically making the connections, and logically configuring the device. Additionally, we can configure IP addresses, routes, routing protocols, etc. All this is done using the EVE-NG server, wherein the users can remotely access the server and configure the devices accordingly. EVE- NG is part of MINT-708 and MINT-720 for the complete lab practice, assignments, and final lab exam.
Production of massless bottom jets in ppbar and pp collisions at next-to-leading order of QCD

description: We present predictions for the inclusive production of bottom jets in proton-antiproton collisions at 1.96 TeV and proton-proton collisions at 7 TeV. The bottom quark is considered massless. In this scheme, we find that at small transverse momentum (p_T) the ratio of the next-to-leading order to the leading-order cross section (K factor) is smaller than one. It increases with increasing p_T and approaches one at larger p_T at a value depending essentially on the choice of the renormalization scale. Adding non-perturbative corrections obtained from PYTHIA Monte Carlo calculations leads to reasonable agreement with experimental b-jet cross sections obtained by the CDF and the CMS collaborations.

description: We analyze radial and azimuthal variations of the phase balance between the molecular and atomic ISM in the Milky Way. In particular, the azimuthal variations -- between spiral arm and interarm regions -- are analyzed without any explicit definition of spiral arm locations. We show that the molecular gas mass fraction, i.e., fmol=H2/ (HI+H2) in mass, varies predominantly in the radial direction: starting from ~100% at the center, remaining ~>50% (~>60%) to R~6kpc, and decreasing to ~10-20% (~50%) at R=8.5 kpc when averaged over the whole disk thickness (in the mid plane). Azimuthal, arm-interarm variations are secondary: only ~20%, in the globally molecule-dominated inner MW, but becoming larger, ~40-50%, in the atom-dominated outskirts. This suggests that in the inner MW, the gas stays highly molecular (fmol>50%) as it goes from an interarm region, into a spiral arm, and back into the next interarm region. Stellar feedback does not dissociate molecules much, and the coagulation and fragmentation of molecular clouds dominate the evolution of the ISM at these radii. The trend differs in the outskirts, where the gas phase is globally atomic (fmol<50%). The HI and H2 phases cycle through spiral arm passage there. These different regimes of ISM evolution are also seen in external galaxies (e.g., LMC, M33, and M51). We explain the radial gradient of fmol by a simple flow continuity model. The effects of spiral arms on this analysis are illustrated in Appendix.

description: We report the revised crystal structure, static and dynamic magnetic properties of quasi-two dimensional honeycomb-lattice silver delafossite Ag3Co2SbO6. The magnetic susceptibility and specific heat data are consistent with the onset of antiferromagnetic long range order at low temperatures with Néel temperature TN ~ 21.2 K. In addition, the magnetization curves revealed a field-induced (spin-flop type) transition below TN in moderate magnetic fields. The GGA+U calculations show the importance of the orbital degrees of freedom, which maintain a hierarchy of exchange interaction in the system. The strongest antiferromagnetic exchange coupling was found in the shortest Co-Co pairs and is due to direct and superexchange interactions between the half-filled xz+yz orbitals pointing directly to each other. The other four out of six nearest neighbor exchanges within the cobalt hexagon are suppressed, since for these bonds active half-filled orbitals turned out to be parallel and do not overlap. The electron spin resonance (ESR) spectra reveal a Gaussian shape line attributed to Co2+ ion in octahedral coordination with average effective g-factor g=2.3+/-0.1 at room temperature and shows strong divergence of ESR parameters below 120 K, which imply an extended region of short-range correlations. Based on the results of magnetic and thermodynamic studies in applied fields, we propose the magnetic phase diagram for the new honeycomb-lattice delafossite.

description: We present measurements of the [NII]/Ha ratio as a probe of gas-phase oxygen abundance for a sample of 419 star-forming galaxies at z=0.6-2.7 from the KMOS3D near-IR multi-IFU survey. The mass-metallicity relation (MZR) is determined consistently with the same sample selection, metallicity tracer, and methodology over the wide redshift range probed by the survey. We find good agreement with long-slit surveys in the literature, except for the low-mass slope of the relation at z~2.3, where this sample is less biased than previous samples based on optical spectroscopic redshifts. In this regime we measure a steeper slope than some literature results. Excluding the AGN contribution from the MZR reduces sensitivity at the high mass end, but produces otherwise consistent results. There is no significant dependence of the [NII]/Ha ratio on SFR or environment at fixed redshift and stellar mass. The IFU data allow spatially resolved measurements of [NII]/Ha, from which we can infer abundance gradients for 180 galaxies, thus tripling the current sample in the literature. The observed gradients are on average flat, with only 15 gradients statistically offset from zero at >3sigma. We have modelled the effect of beam-smearing, assuming a smooth intrinsic radial gradient and known seeing, inclination and effective radius for each galaxy. Our seeing-limited observations can recover up to 70% of the intrinsic gradient for the largest, face-on disks, but only 30% for the smaller, more inclined galaxies. We do not find significant trends between observed or corrected gradients and any stellar population, dynamical or structural galaxy parameters, mostly in agreement with existing studies with much smaller sample sizes. In cosmological simulations, strong feedback is generally required to produce flat gradients at high redshift.

description: Rapid growth in the reliance on teamwork in organizations, coupled with advances in artificial intelligence, has fueled increased use of Human Autonomy Teams (HATs) involving the collaboration of humans and agents to complete work. Although there are many successful examples of HATs, researchers and technology developers can see additional applications if agents were better able to understand the mental states of humans to anticipate what a team is likely to do next. Creating this capability requires the creation of models of team interaction that enable agents to interpret a team's current state and anticipate its future state. To build this model, we draw on research on collective intelligence (CI), which shows a team's capability to work together can be characterized by a latent collective intelligence factor, based on observations of work across a range of tasks, and which predicts a team's ability to accomplish a wide range of goals in the future. While some work uses a specific battery of CI tasks, more recent studies have identified observable collaborative process metrics that can be captured passively. Building on this work, we propose a method of evaluating CI by representing it as a latent variable represented by the hidden state in a Hidden Markov Model. The observations used as input to the model are the team's observable collaborative process behaviors (i.e., collective effort, use of task-related skills, and task-strategy efficiency). We show by learning the set of hidden states representing a team's observed collaborative process behaviors over time, we both learn information about the team's CI, predict how CI will evolve in the future, and suggest when an agent might intervene to improve team performance. Based on the model's observations, we discuss how it can help agents diagnose teamwork and possibly make interventions to improve CI by identifying areas of collaborative process (collective effort, skill use, or task strategy) that could be improved.

description: This article focuses on interpolation subject, in particular, the interpolation of curve bootstrapping. Both linear spline and cubic spline are studied. Although there are a number of advantages to using piecewise cubic splines, there is one major drawback which leads us to go in favour of linear splines. This drawback stems from the fact that the perturbation of one point will affect another point.

description: Solar tornadoes are dark vertical filamentary structures observed in the extreme ultraviolet associated with prominence legs and filament barbs. Their true nature and relationship to prominences requires understanding their magnetic structure and dynamic properties. Recently, a controversy has arisen: is the magnetic field organized forming vertical, helical structures or is it dominantly horizontal? And concerning their dynamics, are tornadoes really rotating or is it just a visual illusion? Here, we analyze four consecutive spectropolarimetric scans of a prominence hosting tornadoes on its legs which help us shed some light on their magnetic and dynamical properties. We show that the magnetic field is very smooth in all the prominence, probably an intrinsic property of the coronal field. The prominence legs have vertical helical fields that show slow temporal variation probably related to the motion of the fibrils. Concerning the dynamics, we argue that 1) if rotation exists, it is intermittent, lasting no more than one hour, and 2) the observed velocity pattern is also consistent with an oscillatory velocity pattern (waves).

description: Rapid growth in the reliance on teamwork in organizations, coupled with advances in artificial intelligence, has fueled increased use of Human Autonomy Teams (HATs) involving the collaboration of humans and agents to complete work. Although there are many successful examples of HATs, researchers and technology developers can see additional applications if agents were better able to understand the mental states of humans to anticipate what a team is likely to do next. Creating this capability requires the creation of models of team interaction that enable agents to interpret a team's current state and anticipate its future state. To build this model, we draw on research on collective intelligence (CI), which shows a team's capability to work together can be characterized by a latent collective intelligence factor, based on observations of work across a range of tasks, and which predicts a team's ability to accomplish a wide range of goals in the future. While some work uses a specific battery of CI tasks, more recent studies have identified observable collaborative process metrics that can be captured passively. Building on this work, we propose a method of evaluating CI by representing it as a latent variable represented by the hidden state in a Hidden Markov Model. The observations used as input to the model are the team's observable collaborative process behaviors (i.e., collective effort, use of task-related skills, and task-strategy efficiency). We show by learning the set of hidden states representing a team's observed collaborative process behaviors over time, we both learn information about the team's CI, predict how CI will evolve in the future, and suggest when an agent might intervene to improve team performance. Based on the model's observations, we discuss how it can help agents diagnose teamwork and possibly make interventions to improve CI by identifying areas of collaborative process (collective effort, skill use, or task strategy) that could be improved.
Density effects in entangled solutions of linear and ring polymers

description: In this paper, we employ Molecular Dynamics computer simulations to study and compare the statics and dynamics of linear and circular (ring) polymer chains in entangled solutions of different densities. While we confirm that linear chain conformations obey Gaussian statistics at all densities, rings tend to crumple becoming more and more compact as density increases. Conversely, contact frequencies between chain monomers are shown to depend on solution density for both chain topologies. Relaxation of chains at equilibrium is also shown to depend on topology, with ring polymers relaxing faster than their linear counterparts. Finally, we discuss the local viscoelastic properties of the solutions by showing that diffusion of dispersed colloid-like particles is markedly faster in the rings case.

Human Trust in Artificial Intelligence Review

name: Woolley, Anita
Publisher: name: Carnegie Mellon University

Subjects: Human Information Behaviour

description: Artificial Intelligence (AI) characterizes a new generation of machines capable of interacting with the environment and aiming to simulate human intelligence. By challenging previously established assumption that technology is fully deterministic and by threatening to change the overall workforce structure, AI provides new theoretical and empirical questions that should be addressed by organizational researchers. The way AI-associated changes are being integrated within organizations depends on workers’ trust in AI. This review presents the empirical research on human trust in AI conducted in multiple disciplines over the last twenty years. Based on the reviewed literature, we organize the existing research into a framework that addresses AI representation as a continuum of embodiment on the one hand and level of machine intelligence on the other. The continuum starts with AI that is fully embedded within an application, such as a search-engine, and ends with a fully physically present robotic entity operated by AI. As the level of machine intelligence and control over the work increases, so does the level of required trust. The features of AI representation and machine intelligence have important implications for the antecedents of trust that in turn play a critical role in enabling AI integration into organizational routines.

description: The transmission eigenvalue problem is an important and challenging topic arising in the inverse scattering theory. In this paper, for the Helmholtz transmission eigenvalue problem, we give a weak formulation which is a nonselfadjoint linear eigenvalue problem. Based on the weak formulation, we first discuss the non-conforming finite element approximation, and prove the error estimates of the discrete eigenvalues obtained by the Adini element, Morley-Zienkiewicz element, modified-Zienkiewicz element et. al. And we report some numerical examples to validate the efficiency of our approach for solving transmission eigenvalue problem.
Self-Assembly of Magnetic Spheres in Strong Homogeneous Magnetic Field

description: The self-assembly in two dimensions of spherical magnets in strong magnetic field is addressed theoretically. %% It is shown that the attraction and assembly of parallel magnetic chains is the result of a delicate interplay of dipole-dipole interactions and short ranged excluded volume correlations. %% Minimal energy structures are obtained by numerical optimization procedure as well as analytical considerations. For a small number of constitutive magnets $N_{\rm tot}\leq26$, a straight chain is found to be stable. In the regime of larger $N_{\rm tot}\geq27$, the magnets form \textit{two touching} chains with equally long tails at both ends. We succeed to identify the transition from \textit{two} to \textit{three} touching chains at $N_{\rm tot}=129$.
Stochastic thermodynamics of resetting

description: Stochastic dynamics with random resetting leads to a non-equilibrium steady state. Here, we consider the thermodynamics of resetting by deriving the first and second law for reset processes far from equilibrium. We identify the contributions to the entropy production of the system which arise due to resetting and show that they correspond to the rate with which information is either erased or created. Using Landauer's principle, we derive a bound on the amount of work that is required to maintain a resetting process. We discuss different regimes of resetting, including a Maxwell's demon scenario where heat is extracted from a bath at constant temperature.

Optimal DoF Region for the Asymmetric Two-Pair MIMO Two-Way Relay Channel

description: In this paper, we study the optimal degrees of freedom (DoF) region for the two-pair MIMO two-way relay channel (TWRC) with asymmetric antenna setting, where two pairs of users exchange information with the help of a common relay. Each user $i$ is equipped with $M_i$ antennas, for $i=1,2,3,4$, and the relay is equipped with $N$ antennas. First, we derive an outer bound of the DoF region by using the cut-set theorem and the genie-message approach. Then, we propose a new transmission scheme to achieve the outer bound of the DoF region. Due to the asymmetric data exchange, where the two users in each pair can communicate a different number of data streams, we not only need to form the network-coded symbols but also need to process the additional asymmetric data streams at the relay. This is realized through the joint design of relay compression matrix and source precoding matrices. After obtaining the optimal DoF region, we study the optimal sum DoF by solving a linear programming problem. From the optimal DoF region of this channel, we show that in the asymmetric antenna setting, some antennas at certain source nodes are redundant and cannot contribute to enlarge the DoF region. We also show that there is no loss of optimality in terms of the sum DoF by enforcing symmetric data exchange, where the two users in each pair are restricted to communicate the same number of data streams.

description: The new generation of power metering system - i.e. Advanced Metering Infrastructure (AMI) - is expected to enable remote reading, control, demand response and other advanced functions, based on the integration of a new two-way communication network, which will be referred as Smart Metering Network (SMN). In this paper, we focus on the design principles of multiple access control (MAC) protocols for SMN. First, we list several AMI applications and its benefits to the current power grid and user experience. Next, we introduces several features of SMN relevant to the design choice of the MAC protocols, including the SMN architecture and candidate communication technologies. After that, we propose some performance evaluation metrics, such as scalability issue, traffic types, delay and etc, and give a survey of the associated research issues for the SMN MAC protocols design. In addition, we also note progress within the new IEEE standardization task group (IEEE 802.11ah TG) currently working to create SMN standards, especially in the MAC protocols aspect.

description: Single photon sources (SPS) are a fundamental building block for optical implementations of quantum information protocols. Among SPSs, multiple crystal heralded single photon sources seem to give the best compromise between high pair production rate and low multiple photon events. In this work, we study their performance in a practical quantum key distribution experiment, by evaluating the achievable key rates. The analysis focuses on the two different schemes, symmetric and asymmetric, proposed for the practical implementation of heralded single photon sources, with attention on the performance of their composing elements. The analysis is based on the protocol proposed by Bennett and Brassard in 1984 and on its improvement exploiting decoy state technique. Finally, a simple way of exploiting the post-selection mechanism for a passive, one decoy state scheme is evaluated.

description: A short review on the self-consistent RPA based on a energy-density functional of the Skyrme type is given. We also present an extension of the RPA where the coupling of phonons to the single-particle states is considered. Within this approach we present numerical results which are compared with data. The self-consistent approach is compared with the Landau-Migdal theory. Here we derive from the self-consistent $ph$ interaction, the Landau-Migdal parameters as well as their density dependence. In the Appendix a new derivation of the reduced matrix elements of the $ph$ interaction is presented.
