Self-Similar Conformations and Dynamics in Entangled Melts and Solutions of Nonconcatenated Ring Polymers
Creators: name: Rubinstein, Michael

Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: A scaling model of self-similar conformations and dynamics of nonconcatenated entangled ring polymers is developed. Topological constraints force these ring polymers into compact conformations with fractal dimension d f = 3 that we call fractal loopy globules (FLGs). This result is based on the conjecture that the overlap parameter of subsections of rings on all length scales is the same and equal to the Kavassalis-Noolandi number O KN ≈ 10-20. The dynamics of entangled rings is self-similar and proceeds as loops of increasing sizes are rearranged progressively at their respective diffusion times. The topological constraints associated with smaller rearranged loops affect the dynamics of larger loops through increasing the effective friction coefficient but have no influence on the entanglement tubes confining larger loops. As a result, the tube diameter defined as the average spacing between relevant topological constraints increases with time t , leading to "tube dilation". Analysis of the primitive paths in molecular dynamics simulations suggests a complete tube dilation with the tube diameter on the order of the time-dependent characteristic loop size. A characteristic loop at time t is defined as a ring section that has diffused a distance equal to its size during time t . We derive dynamic scaling exponents in terms of fractal dimensions of an entangled ring and the underlying primitive path and a parameter characterizing the extent of tube dilation. The results reproduce the predictions of different dynamic models of a single nonconcatenated entangled ring. We demonstrate that traditional generalization of single-ring models to multi-ring dynamics is not self-consistent and develop a FLG model with self-consistent multi-ring dynamics and complete tube dilation. This selfconsistent FLG model predicts that the longest relaxation time of nonconcatenated entangled ring polymers scales with their degree of polymerization N as τ relax ~ N 7/3 , while the diffusion coefficient of these rings scales as D 3d ~ N -5/3 . For the entangled solutions and melts of rings, we predict power law stress relaxation function G ( t ) ~ t -3/7 at t < τ relax without a rubbery plateau and the corresponding viscosity scaling with the degree of polymerization N as η ~ N 4/3 . These theoretical predictions are in good agreement with recent computer simulations and are consistent with experiments of melts of nonconcatenated entangled rings.

description: To what extent does the maximal subfield spectrum of a division algebra determine the isomorphism class of that algebra? It has been shown that over some fields a quaternion division algebra's isomorphism class is largely if not entirely determined by its maximal subfield spectrum. However in this paper, we show that there are fields for which the maximal subfield spectrum says little to nothing about a quaternion division algebra's isomorphism class. We give an explicit construction of a division algebra with infinite genus. Along the way we introduce the notion of a "linking field extension," which we hope will be of independent interest. We go on to show that there exists a field K for which (1) there are infinitely many nonisomorphic quaternion division algebras with center K, and (2) any two quaternion division algebra with center K are pairwise weakly isomorphic. In fact we show that there are infinitely many nonisomorphic fields satisfying these two conditions.

description: Computer simulation with Monte Carlo is an important tool to investigate the function and equilibrium properties of many systems with biological and soft matter materials solvable in solvents. The appropriate treatment of long-range electrostatic interaction is essential for these charged systems, but remains a challenging problem for large-scale simulations. We have developed an efficient Barnes-Hut treecode algorithm for electrostatic evaluation in Monte Carlo simulations of Coulomb many-body systems. The algorithm is based on a divide-and-conquer strategy and fast update of the octree data structure in each trial move through a local adjustment procedure. We test the accuracy of the tree algorithm, and use it to perform computer simulations of electric double layer near a spherical interface. It has been shown that the computational cost of the Monte Carlo method with treecode acceleration scales as $\log N$ in each move. For a typical system with ten thousand particles, by using the new algorithm, the speed has been improved by two orders of magnitude from the direct summation.

Confronting Affliction: How Violent Offenders Navigate Faith-Based Restorative Justice in Prison
Creators: name: , Corey
Publisher: name: University of Chicago
Year: 2021

description: Restorative justice has been expanding for decades in the U.S. as an alternative or compliment to the traditional criminal justice system. But it’s still infrequently used with adults who have committed violent crimes, as opposed to more gently treated teenage offenders. After talking with a small group of former offenders and facilitators who participated in a restorative justice program in Texas prisons, I found that offenders begin the restorative justice program interpreting themselves as victims. Displacing blame and culpability onto others rather than reckon with the harm they committed, offenders feel persecuted by a system that does not acknowledge their complicated identities of being both harmer and harmed. The restorative justice program in which they participated, Bridges To Life, offers acknowledgement and acceptance, thereby encouraging offender accountability and forgiveness through its ideological construct of a benevolent God.

description: In this paper, we study the decoherence and entanglement properties for the two site Bose-Hubbard model in the presence of a non-linear damping. We apply the techniques of thermo field dynamics and then use Hartree-Fock approximation to solve the corresponding master equation. The expectation values of the approximated field operators appearing in the solution of master equation, are computed self-consistently. We solve this master equation for a small time $t$ so that we get the analytical solution, thereby we compute the decoherence and entanglement properties of the solution of the two-mode bosonic system.
Image Segmentation for Quantification of Air-Water Interface in Micro-CT Soil Images
Creators: name: Potteti, Kranthi Kumar
Publisher: name: University of Nevada, Las Vegas
Year: 2012

description: Soils are complex environments comprising various biological (roots, water, air etc) and physical constituents (minerals, aggregates, etc). Synchrotron radiation based X-ray microtomography (XMT) is widely used in extracting qualitative and quantitative information regarding spatial distribution of biological and physical soil constituents. Segmentation of these micro-CT soil images is of interest to geologists, hydrologists, civil and petroleum engineers and soil scientists. In this present work, we study and implement segmentation algorithms for microhydrology studies, specifically for soil water conductivity. Three well-known image segmentation algorithms are studied for evaluating their performance for the task. We demonstrate the problems and ways to segment XMT images and extract data for evaluating the air pressure in the soil pores to promote soil hydrology studies. To this end we take the recommended in the literature approach to differentiate textures and segment images using Fuzzy C-means Clustering (FCM). Secondly, we demonstrate the performance of two state-of-the-art level-set based active contours methods followed by curve fitting for radii detection and air pressure calculation.

description: In the past years many possible extensions of the Standard Model (SM) have been investigated. If one of this model is revealed at the LHC, we will need tools to distinguish it among the many others studied. One possibility to achieve this goal is to utilize the forward-backward asymmetry. In this paper we calculate the asymmetry for a model in which there is an extra U(1) anomalous symmetry. Furthermore, we show that the asymmetry can be used to impose constraints on the free parameters of the model.

description: In April 2021, the European Commission proposed a Regulation on Artificial Intelligence (AI) as part of a package of EU legislative harmonization measures that seek to tackle the societal challenges of digitalization and technological innovation. The proposed legislation draws heavily on the “New Approach” technique for the technical harmonization and standardization of goods. This raises several questions and concerns. Firstly, it can be questioned whether a harmonization technique that has been developed for health and safety standards in the offline, physical market, can be that easily transposed to the field of AI, where ethical and fundamental rights issues abound. Secondly, despite its success, the “New Approach” regulatory technique has been subject to much criticism, such as the responsibility of the manufacturers to carry out a conformity assessment, the role and decision-making powers of the private law standardization organizations and notified bodies, and the lack of public participation and public oversight in standardization and certification processes. These concerns are aggravated in the AI environment due to the pertaining legal, ethical and fundamental rights issues. This Article therefore seeks to explore the future-proofness of the proposed AI Act from three perspectives: i) the internal market; ii) protection of fundamental rights and iii) democratic legitimacy in the EU decision-making processes. Ultimately, it offers a broader reflection on the policy and legal implications of AI and proposes a number of recommendations on how to increase the fitness of the future AI Act, bearing in mind the balance between the economic and fundamental rights goals of the AI Regulation.
Discrete symmetries, roots of unity, and lepton mixing

description: We investigate the possibility that the first column of the lepton mixing matrix U is given by u_1 = (2,-1,-1)^T/sqrt{6}. In a purely group-theoretical approach, based on residual symmetries in the charged-lepton and neutrino sectors and on a theorem on vanishing sums of roots of unity, we discuss the finite groups which can enforce this. Assuming that there is only one residual symmetry in the Majorana neutrino mass matrix, we find the almost unique solution Z_q x S_4 where the cyclic factor Z_q with q = 1,2,3,... is irrelevant for obtaining u_1 in U. Our discussion also provides a natural mechanism for achieving this goal. Finally, barring vacuum alignment, we realize this mechanism in a class of renormalizable models.

description: A systematic study is made, for an arbitrary finite relational language with at least one symbol of arity at least 2, of classes of nonrigid finite structures. The well known results that almost all finite structures are rigid and that the class of finite structures has a zero-one law are, in the present context, the first layer in a hierarchy of classes of finite structures with increasingly more complex automorphism groups. Such a hierarchy can be defined in more than one way. For example, the $k$th level of the hierarchy can consist of all structures having at least $k$ elements which are moved by some automorphism. Or we can consider, for any finite group $G$, all finite structures $\mathcal{M}$ such that $G$ is a subgroup of the group of autmorphisms of $\mathcal{M}$; in this case the "hierarchy" is a partial order. In both cases, as well as variants of them, each "level" satisfies a logical limit law, but not a zero-one law (unless $k = 0$ or $G$ is trivial). Moreover, the number of (labelled or unlabelled) $n$-element structures in one place of the hierarchy divided by the number of $n$-element structures in another place always converges to a rational number or to $\infty$ as $n \to \infty$. All instances of the respective result are proved by an essentially uniform argument.

Information was obtained from five companies: American Motors, Chrysler, Ford, General Motors, and Studebaker-Packard.
title: Wind flow modeling for wind energy analysis of the Nellis Dunes area in Nevada
Creators: name: Rangegowda, Upendra
Publisher: name: University of Nevada, Las Vegas
Year: 2010

description: A wind energy analysis of the Nellis Dunes area in Nevada was conducted. A DEM file which contains the elevation data was used to generate the surface model and to create a 3-D mesh of the region. Local meteorological tower data collected for a period of one year was used to generate the diagnostic initial wind fields. Upper level wind fields were created using a surface boundary layer technique along with linear interpolation of the tower level wind fields. The vertical components of the velocities were adjusted using the equation of continuity. Mass consistent 3-D wind fields were then calculated using the finite element method. Divergence reduction of the complete wind field was conducted using an iterative procedure.
The statistical analysis of the measured monthly averaged wind data was also performed. The velocity distribution analysis of the measured data was undertaken, and showed a good fit with the Weibull distribution of wind velocity. The wind rose diagrams for all the tower locations were plotted to obtain the monthly averaged wind directions for the entire year.
The wind velocities generated from the mass-consistent wind model were used as input to calculate wind power density maps. Monthly wind power density maps for the entire year were generated. The potential locations for establishing a wind farm is discussed.

description: Error correction of sequenced reads remains a difficult task, especially in single-cell sequencing projects with extremely non-uniform coverage. While existing error correction tools designed for standard (multi-cell) sequencing data usually come up short in single-cell sequencing projects, algorithms actually used for single-cell error correction have been so far very simplistic. We introduce several novel algorithms based on Hamming graphs and Bayesian subclustering in our new error correction tool BayesHammer. While BayesHammer was designed for single-cell sequencing, we demonstrate that it also improves on existing error correction tools for multi-cell sequencing data while working much faster on real-life datasets. We benchmark BayesHammer on both $k$-mer counts and actual assembly results with the SPAdes genome assembler.
Petrogenesis of the East Fork Member Rhyolites, Valles Caldera, New Mexico, USA
Creators: name: Eichler, Carla
Publisher: name: University of Nevada, Las Vegas
Year: 2012

description: The most recent volcanism in the Valles caldera is represented by the El Cajete Pyroclastic Beds (ECPB), Battleship Rock Ignimbrite (BRI), and Banco Bonito Flow (BBF) as well as the VC-1 rhyolite, which are collectively known as the East Fork Member (EFM) of the Valles Rhyolite. The EFM was erupted at approximately 55 ka and 40 ka after an approximate 460 ka lull in volcanism. Previous studies suggested a mafic intrusion at depth triggered the eruptions. This thesis represents the first detailed study of the EFM.
Crystal assemblages consist of plagioclase, biotite, clinopyroxene, orthopyroxene, amphibole, sanidine, quartz, and oxides. Electron probe microanalysis and detailed petrography indicates that two distinct crystal populations are present in the ECPB, BRI, and BBF. Large (1 mm), typically resorbed or subhedral crystals represent one population, and small (0.5 mm), generally euhedral crystals represent the other. The large resorbed plagioclase crystals typically have rim overgrowths. Both normal and reverse zonation is present. 40Ar/39Ar geochronology performed on euhedral biotite and groundmass glass from the BBF returned isochron ages of 478 ± 27 ka and 575 ± 15 ka and total gas ages of 125.01 ± 1 ka and 129.82 ± 0.80 ka, respectively. High Mg numbers of large euhderal biotite and 40Ar/39Ar ages older than the accepted age range indicate these crystals are xenocrystic. Radiogenic isotopes are consistent with mixing between the mantle and lower crustal reservoirs. General trends are evident between whole-rock major and trace elements with increasing SiO2. In general, incompatible trace elements increase and compatible trace elements decrease. Incompatible trace element ratios indicate the presence of a single magma batch.
The heterogeneity in crystal morphology and chemistry can be explained by a model in which partial melting of mid- to deep continental crust occurred due to an intrusion of an intermediate composition magma. Magma mixing and an exchange of crystals took place between the partial melt and the intruding magma. The hybrid magma rose to the upper crust. Trends in the trace element data indicates fractional crystallization was the last process to take prior to eruption. The geochemical and isotopic data from this study are best explained by a modified version of the rapid production and eruption model put forth by Huppert and Sparks (1988).

An Estimate of Groundwater Recharge in the Nabogo River Basin, Ghana Using Water Table Fluctuation Method and Chloride Mass Balance
Creators: name: Krautstrunk, Melanie Lynn
Publisher: name: University of Nevada, Las Vegas
Year: 2012

description: The Cambrian-Precambrian fractured sandstone aquifer in the Nabogo River Basin in the Sahelian Northern Region in Ghana is one of the most important sources for fresh water supply for the local rural communities there. Recent population growth and commercial agricultural interests in this region could have an impact on this critical water resource. Groundwater recharge estimates are determined in this study using the Water Table Fluctuation Method and Chloride Mass Balance and can be applied to future sustainability studies of the region's water resources. Recharge estimates of the Water Table Fluctuation Method are in a range of 10-143 mm/yr or 1-13% of annual rainfall. Chloride Mass Balance groundwater recharge estimates show an annual recharge of 37.06 mm/yr. or 4% of annual precipitation. Recharge source is determined to be from local meteoric waters using stable isotopic analysis of Oxygen (?18O) and Deuterium (?D). The limitations, advantages and disadvantages of these methods are discussed in this study as well as the possibilities for future research.
Thermodynamics of a Bose gas near the superfluid--Mott-insulator transition

Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We study the thermodynamics near the generic (density-driven) superfluid--Mott-insulator transition in the three-dimensional Bose-Hubbard model using the nonperturbative renormalization-group approach. At low energy the physics is controlled by the Gaussian fixed point and becomes universal. Thermodynamic quantities can then be expressed in terms of the universal scaling functions of the dilute Bose gas universality class while the microscopic physics enters only {\it via} two nonuniversal parameters, namely the effective mass $m^*$ and the "scattering length" $a^*$ of the elementary excitations at the quantum critical point between the superfluid and Mott-insulating phase. A notable exception is the condensate density in the superfluid phase which is proportional to the quasi-particle weight $\Zqp$ of the elementary excitations. The universal regime is defined by $m^*a^*{}^2 T\ll 1$ and $m^*a^*{}^2|δμ|\ll 1$, or equivalently $|\bar n-\bar n_c|a^*{}^3\ll 1$, where $δμ=μ-μ_c$ is the chemical potential shift from the quantum critical point $(μ=μ_c,T=0)$ and $\bar n-\bar n_c$ the doping with respect to the commensurate density $\bar n_c$ of the T=0 Mott insulator. We compute $\Zqp$, $m^*$ and $a^*$ and find that they vary strongly with both the ratio $t/U$ between hopping amplitude and on-site repulsion and the value of the (commensurate) density $\bar n_c$. Finally, we discuss the experimental observation of universality and the measurement of $\Zqp$, $m^*$ and $a^*$ in a cold atomic gas in an optical lattice.

Exploring Reasons Why Men and Women Refrain from Sex Despite Desire
Creators: name: Lanti, Alessandra
Publisher: name: University of Nevada, Las Vegas
Year: 2012

description: Sexual behavior has been found to be an unreliable referent for sexual desire. Numerous studies have found that sexual activity is motivated by a range of non-desire related factors, from the promotion of intimacy to the seeking of new experiences. Sexual desire may also be an unreliable predictor of sexual activity. There is a dearth of research, however, on the reasons why individuals choose not to have sex despite the presence of desire for a willing partner. The main aim of this study is to qualitatively investigate the reasons why people refrain from sex when they feel desire for a willing partner. A secondary aim is to investigate differences in the reasons generated depending on whether desire is defined amorphously, physiologically or subjectively. The ultimate aim for future study is the construction and validation of the Bigger Than Desire Questionnaire (BTDQ) that will serve as a quantitative investigation of these reasons. In order to truly understand the sexual desire-sexual activity relationship, it is important to understand both why people have sex without desire and why people refrain from having sex despite desire.

description: A simple quantum model describing the onset of time is presented. This is combined with a simple quantum model of the onset of space. A major purpose is to explore the interpretational issues which arise. The state vector is a superposition of states representing "instants." The sample space and probability measure are discussed. Critical to the dynamics is state vector collapse: it is argued that a tenable interpretation is not possible without it. Collapse provides a mechanism whereby the universe size, like a clock, is narrowly correlated with the quantized time eigenvalues.

Professional Image and Heroism of Nurses during the Covid-19 Pandemic: A Case Study of the Effects of Social Media on Nurses in Illinois

Subjects: subject: Nurse
subject: Covid-19

subject: Social Media

description: This article uses a survey of nurses in Illinois to explore the heroization of nurses that occurred during the 2020-2021 pandemic and the effects of social media on respondents. Due to their hard work taking care of patients, putting them at risk of contracting the Covid-19, nurses have become viewed as heroic. Other scholars have examined the narratives of heroism surrounding nurses, finding they have both accepted and critiqued their status as heroes. However, there have not been many specific studies of the effects of social media on the heroization process and on nurses during the pandemic. Social media has allowed nurses to publicize their jobs and daily struggles, leading to their status as heroes and general acknowledgement, but can also negatively affect their mental health. In addition, relatively little online discourse about nurses transformed into offline activism, casting doubt on the limits of social media in politics.

We could observe spin transport over lengths up to 20 μm at room temperature, the largest distance measured so far for graphene. Due to enhanced charge carrier diffusion, spin relaxation lengths are measured up to 4.5 μm. The relaxation times are similar to values for lower quality SiO$_2$ based devices, around 200 ps. We find that the relaxation rate is determined in almost equal measures by the Elliott-Yafet and D'Yakonov-Perel mechanisms.

title: The Effect of Human Exposure on the Anti-predatory Response of Harbor Seals (Phoca vitulina)
Creators: name: Olson, Jennifer Kathryn
Publisher: name: Western Washington University
Year: 2013

description:
Increased exposure to anthropogenic activities often results in animals developing higher tolerance to activities that would otherwise disturb them. Although this response is sometimes viewed as a beneficial survival mechanism, habituation to human activities may lead to negative consequences, such as decreased predator aversion. Due to their healthy population status, the numerous and varied locations of their haul-out sites and their anti-predatory response to bald eagles, harbor seals in the Salish Sea are an ideal study system to answer questions concerning the effects of human exposure on wildlife. To examine my hypothesis that increased human exposure reduces anti-predatory response in harbor seals, I used instantaneous scan-sampling techniques to compare the behavioral responses of seals to bald eagles and to humans at six haul-out sites with varying levels of exposure to anthropogenic activities. Sites were classified as high exposure (6.07 ± SE 0.73 boats • h-1, n=2 sites), medium exposure (1.56 ± SE 0.38 boats • h-1, n=2 sites), and low exposure (0.26 ± SE 0.12 boats • h-1, n=2 sites). Based on generalized linear mixed-effects models (GLMM), the presence of harbor seal anti-predatory response to bald eagles was significantly related to human exposure but not to eagle exposure. Seals showed an anti-predatory response to eagles more often at low-exposure sites (77.17%, n=127 events) than at medium- (60.0%, n=15 events) or high- (45.45%, n=33 events) exposure sites. Also based on GLMMs, human exposure significantly influenced harbor seal response to boat traffic. Seals reacted to passing boats more often at low-exposure sites (100%, n=10 events) than at medium- (77.8%, n=72 events) or high- (83.2%, n=208 events) exposure sites. This study provides the first empirical evidence outside of an urban setting to support the hypothesis that increased interactions with humans can lead to a reduction in overall predator aversion. This finding highlights the potential impact that increased human exposure can have on the predation risk of wildlife populations and disputes the traditionally accepted view of habituation as having little-to-no impact on the animals involved.

Hot versus Cold: the Dichotomy in Spherical Accretion of Cooling Flows onto Supermassive Black Holes in Elliptical Galaxies, Galaxy Groups and Clusters

description: Feedback heating from active galactic nuclei (AGNs) has been commonly invoked to suppress cooling flows predicted in hot gas in elliptical galaxies, galaxy groups and clusters. Previous studies have focused on if and how AGN feedback heats the gas, but little paid attention to its triggering mechanism. Using spherically symmetric simulations, we investigate how large-scale cooling flows are accreted by central supermassive black holes (SMBHs) in eight well-observed systems and find an interesting dichotomy. In massive clusters, the gas develops a central cooling catastrophe within about the cooling time (typically ~ 100 - 300 Myr), resulting in a cold-mode accretion onto SMBHs. However, in our four simulated systems on group and galaxy scales at a low metallicity Z=0.3Z_{sun}, the gas quickly settles into a long-term state which has a cuspy central temperature profile extending to several tens to about 100 pc. At the more realistic solar metallicity, two groups (with R_{e} ~ 4 kpc) still host the long-term hot-mode accretion. Both accretion modes naturally appear in our idealized calculations where only cooling, gas inflow, and compressional heating are considered. The long-term hot-mode accretion is maintained by the quickly-established closeness between the timescales of these processes, preferably in systems with low gas densities, low gas metallicities, and importantly, compact central galaxies, which result in strong gravitational acceleration and compressional heating at the intermediate radii. Our calculations predict that central cuspy temperature profiles appear more often in smaller systems than galaxy clusters, which instead often host significant cold gas and star formation.

Fertility symbols in rock art: Cupuls and incised grooves in the Lower Pecos, Texas
Creators: name: Connolly, Cara D.
Publisher: name: University of Nevada, Las Vegas
Year: 2011

description: Rock art at archaeological sites are often dismissed as a culturally symbolic representation that cannot be objectively or scientifically analyzed or interpreted adequately. Such dismissals are detrimental to understanding all aspects of a given culture. Although uninformed interpretations of rock art panels are counterproductive, systematic recording and the testing of different hypotheses is a valid way to begin to better understand the possible range of social functions of rock art. This research examines whether indigenous women's fertility is represented in rock art depictions, known as cupules and groove marks, in the archaeological record. Cupules are defined as a boulder or rock slab covered with small rounded depressions (cupules), usually four to six centimeters in diameter and two to three centimeters in depth. Groove marks are deeply and narrowly incised lines, usually in the shape of a "V" or "W" rarely more than a quarter-inch in depth. In this project, I systematically document and contextualize the pit and groove rock art style in the Lower Pecos, Texas. I also test whether cupules and groove marks are tied to a functional purpose with an experimental project.

Symmetries of cyclic work distributions for an isolated harmonic oscillator

description: We have calculated the distribution of work $W$ done on a 1-d harmonic oscillator that is initially in canonical equilibrium at temperature $T$, then thermally isolated and driven by an arbitrary time-dependent cyclic spring constant $κ(t)$, and demonstrated that it satisfies $P(W)=\exp(βW)P(-W)$, where $β=1/k_{B}T$, in both classical and quantum dynamics. This differs from the celebrated Crooks relation of nonequilibrium thermodynamics, since the latter relates distributions for forward and backward protocols of driving. We show that it is a special case of a symmetry that holds for non-cyclic work processes on the isolated oscillator, and that consideration of time reversal invariance shows it to be consistent with the Crooks relation. We have verified that the symmetry holds in both classical and quantum treatments of the dynamics, but that inherent uncertainty in the latter case leads to greater fluctuations in work performed for a given process.

description: Acyclic directed mixed graphs (ADMGs) are graphs that contain directed ($\rightarrow$) and bidirected ($\leftrightarrow$) edges, subject to the constraint that there are no cycles of directed edges. Such graphs may be used to represent the conditional independence structure induced by a DAG model containing hidden variables on its observed margin. The Markovian model associated with an ADMG is simply the set of distributions obeying the global Markov property, given via a simple path criterion (m-separation). We first present a factorization criterion characterizing the Markovian model that generalizes the well-known recursive factorization for DAGs. For the case of finite discrete random variables, we also provide a parameterization of the model in terms of simple conditional probabilities, and characterize its variation dependence. We show that the induced models are smooth. Consequently, Markovian ADMG models for discrete variables are curved exponential families of distributions.
