Automated Verification Of Role-Based Access Control Policies Constraints Using Prover9
Creators: name: Sabri, Khair Eddin
Publisher: name: arXiv

Subjects: subject: Cryptography and Security (cs.CR)
subject: FOS: Computer and information sciences

description: Access control policies are used to restrict access to sensitive records for authorized users only. One approach for specifying policies is using role based access control (RBAC) where authorization is given to roles instead of users. Users are assigned to roles such that each user can access all the records that are allowed to his/her role. RBAC has a great interest because of its flexibility. One issue in RBAC is dealing with constraints. Usually, policies should satisfy pre-defined constraints as for example separation of duty (SOD) which states that users are not allowed to play two conflicting roles. Verifying the satisfiability of constraints based on policies is time consuming and may lead to errors. Therefore, an automated verification is essential. In this paper, we propose a theory for specifying policies and constraints in first order logic. Furthermore, we present a comprehensive list of constraints. We identity constraints based on the relation between users and roles, between roles and permission on records, between users and permission on records, and between users, roles, and permission on records. Then, we use a general purpose theorem prover tool called Prover9 for proving the satisfaction of constraints.

Quantum ergodic restriction for Cauchy data: Interior QUE and restricted QUE

description: We prove a quantum ergodic restriction theorem for the Cauchy data of a sequence of quantum ergodic eigenfunctions on a hypersurface H of a Riemannian manifold (M, g). The technique of proof is to use a Rellich type identity to relate quantum ergodicity of Cauchy data on H to quantum ergodicity of eigenfunctions on the global manifold M. This has the interesting consequence that if the eigenfunctions are quantum unique ergodic on the global manifold M, then the Cauchy data is automatically quantum unique ergodic on H with respect to operators whose symbols vanish to order one on the glancing set of unit tangential directions to H.

description: Traditional robots are made of rigid structures, which often can become an operational constraint when walking thin paths or maneuvering delicate items. Soft robots can be a more coherent option in these situations because they are built using flexible and resilient smart materials, such as elastomers and gels. Smart materials can alter their shape and properties when subject to external stimuli, such as magnetic fields, electric fields, heat, chemical reactions, pressure variation, light, or photonic processes. Soft robots present many advantageous attributes, such as lightness, compactness, and biocompatibility, but they usually do not offer precise motion control. Magnetic fields are an excellent method of untethered actuation due to their ability to penetrate various materials and provide fast responses without physical attachment. Two different bioinspired soft robots were tested using magnetic actuation. Characterization and analyses of their locomotion modes and behavior were performed and compared. Robots successfully lifted and carried payloads twelve times their body weight, proving to be noticeably effective for untethered applications.

Spin nematic fluctuations near a spin-density-wave phase

description: We study an interacting electronic system exhibiting a spin nematic instability. Using a phenomenological form for the spin fluctuation spectrum near the spin-density-wave (SDW) phase, we compute the spin nematic susceptibility in energy and momentum space as a function of temperature and the magnetic correlation length xi. The spin nematic instability occurs when xi reaches a critical value xi_{cr}, i.e., its transition temperature T_{SN} is always higher than the SDW critical temperature T_{SDW}. In particular, xi_{cr} decreases monotonically with increasing T_{SN}. Concomitantly, low-energy nematic fluctuations are present in a wider temperature region as T_{SN} becomes higher. Approaching the spin nematic instability, the nematic spectral function at zero momentum exhibits a central peak as a function of energy for a finite temperature and a soft mode at zero temperature. These properties originate from the general feature that the imaginary part of the spin-fluctuation bubble has a term linear in energy and its coefficient is proportional to the square of temperature. Furthermore we find that the nematic spectral function exhibits a diffusive peak around zero momentum and zero energy without clear dispersive features. A possible phase diagram for the spin nematic and SDW transitions is also discussed.

description: New two dimensional systems like surface of topological insulator and graphene offer a possibility to experimentally investigate situations considered "exotic" just a decade ago. One of those is the quantum phase transition of the "chiral" type in electronic systems with relativistic spectrum. Phonon mediated ("conventional") pairing in the Dirac semimetal appearing on the surface of topological insulator leads to transition into a chiral superconducting state, while exciton condensation in these gapless systems has been envisioned long time ago in the physics of the narrow band semiconductors. Starting from the microscopic Dirac Hamiltonian with local attraction or repulsion, the BCS type gaussian approximation is developed in the framework of functional integrals. It is shown that due to an "ultra-relativistic" dispersion relation there is a quantum critical point governing the zero temperature transition to a superconducting or the exciton condensed state. The quantum transitions that have critical exponents very different from the conventional ones. They belong to the chiral universality class. We discuss the application of these results to recent experiments in which surface superconductivity was found in topological insulators and estimate feasibility of the phonon pairing.

description: We show that the triply graded Khovanov-Rozansky homology of the torus link $T_{n,k}$ stablizes as $k\to \infty$. We explicitly compute the stable homology (as a ring), which proves a conjecture of Gorsky-Oblomkov-Rasmussen-Shende. To accomplish this, we construct complexes $P_n$ of Soergel bimodules which categorify the Young symmetrizers corresponding to one-row partitions and show that $P_n$ is a stable limit of Rouquier complexes. A certain derived endomorphism ring of $P_n$ computes the aforementioned stable homology of torus links.

description: Some new statistics are proposed to test the uniformity of random samples in the multidimensional unit cube [0; 1]d (d ≥ 2): These statistics are derived from number-theoretic or quasi-Monte Carlo methods for measuring the discrepancy of points in [0; 1]d. Under the null hypothesis that the samples are independent and identically distributed with a uniform distribution in [0; 1]d, we obtain some asymptotic properties of the new statistics. By Monte Carlo simulation, it is found that the nite-sample distributions of the new statistics are well approximated by the standard normal distribution, N(0; 1), or the chi-squared distribution, X2(2). A power study is performed, and possible applications of the new statistics to testing general multivariate goodness-of-t problems are discussed.

description: We have recently reported a new mechanism of colossal magnetoresistance in electron doped Mn oxypnictides NdMnAsO1-xFx. Magnetoresistances of up to -95 percent at 3 K have been observed. Here we show that upon replacing Nd for Pr, the CMR is surprisingly no longer present. Instead a sizeable negative magnetoresistance is observed for PrMnAsO0.95F0.05 below 35 K (MR7T (12 K) = -13.4 percent for PrMnAsO0.9F0.05. A detailed neutron and synchrotron X-ray diffraction study of PrMnAsO0.95F0.05 has been performed, which shows that a structural transition, Ts, occurs at 35 K from tetragonal P4/nmm to orthorhombic Pmmn symmetry. The structural transition is driven by the Pr 4f electrons degrees of freedom.

description: The state equation of the charged AdS black hole is reviewed in the $T-r$ plane. Thinking of the phase transition, the $T-S$, $P-V$, $P-ν$ graphs are plotted and then the equal area law is used in the three cases to get the phase transition point (P,T). The analytical phase transition point relations for P-T of charged AdS black hole has been obtained successfully. By comparing the three results, we find that the equal area law possibly cannot be used directly for $P-ν$ plane. According to the $T-S$, $P-V$ results, we plot the $P-T-Q$ graph and find that for a highly charged black hole a very low temperature condition is required for the phase transition.

description: Shrikes use their beaks for procuring, dispatching and processing their arthropod and vertebrate prey. However, it is not clear how the raptor-like bill of this predatory songbird functions to kill vertebrate prey that may weigh more than the shrike itself. Using high-speed videography, we observed that upon seizing prey with their beaks, shrikes performed rapid (6–17 Hz; 49–71 rad s−1) axial head-rolling movements. These movements accelerated the bodies of their prey about their own necks at g-forces of approximately 6 g, and may be sufficient to cause pathological damage to the cervical vertebrae and spinal cord. Thus, when tackling relatively large vertebrates, shrikes appear to use inertial forces of their prey's own body against them.

On the Closedness of the Linear Image of a Closed Convex Cone
Creators: name: Pataki, Gabor

Year: 2007

description: When is the linear image of a closed convex cone closed? We present very simple, and intuitive necessary conditions, which unify, and generalize seemingly disparate, classical sufficient conditions: polyhedrality of the cone, and “Slater” type conditions are necessary and sufficient, when the dual cone belongs to a class, that we call nice cones. Nice cones subsume all cones amenable to treatment by efficient optimization algorithms: for instance, polyhedral, semidefinite, and p-cones. provide similarly attractive conditions for an equivalent problem: the closedness of the sum of two closed convex cones.

description: This paper presents a novel decentralized control strategy for a multi-robot system that enables parallel multi-target exploration while ensuring a time-varying connected topology in cluttered 3D environments. Flexible continuous connectivity is guaranteed by building upon a recent connectivity maintenance method, in which limited range, line-of-sight visibility, and collision avoidance are taken into account at the same time. Completeness of the decentralized multi-target exploration algorithm is guaranteed by dynamically assigning the robots with different motion behaviors during the exploration task. One major group is subject to a suitable downscaling of the main traveling force based on the traveling efficiency of the current leader and the direction alignment between traveling and connectivity force. This supports the leader in always reaching its current target and, on a larger time horizon, that the whole team realizes the overall task in finite time. Extensive Monte~Carlo simulations with a group of several quadrotor UAVs show the scalability and effectiveness of the proposed method and experiments validate its practicability.

Variational Inequalities over Perturbed Polyhedral Convex Sets

description: This paper provides conditions for existence of a locally unique, Lipschitzian solution of a linear variational inequality posed over a polyhedral convex set in Rn under perturbation of either or both of the constant term in the variational inequality and the right-hand side of the system of linear constraints de ning its feasible set. Conditions for perturbation of just the constant term are well known. Here we show that a suitable extension of those conditions suffices for the more general case in which the right-hand side of the constraints varies also. As a consequence, we obtain existence, uniqueness, and Lipschitz continuity properties of solutions of nonlinear variational inequalities posed over perturbed polyhedral convex sets.

description: The role of disk instabilities, such as bars and spiral arms, and the associated resonances, in growing bulges in the inner regions of disk galaxies have long been studied in the low-redshift nearby Universe. There it has long been probed observationally, in particular through peanut-shaped bulges. This secular growth of bulges in modern disk galaxies is driven by weak, non-axisymmetric instabilities: it mostly produces pseudo-bulges at slow rates and with long star-formation timescales. Disk instabilities at high redshift (z>1) in moderate-mass to massive galaxies (10^10 to a few 10^11 Msun of stars) are very different from those found in modern spiral galaxies. High-redshift disks are globally unstable and fragment into giant clumps containing 10^8-10^9 Msun of gas and stars each, which results in highly irregular galaxy morphologies. The clumps and other features associated to the violent instability drive disk evolution and bulge growth through various mechanisms, on short timescales. The giant clumps can migrate inward and coalesce into the bulge in a few 10^8 yr. The instability in the very turbulent media drives intense gas inflows toward the bulge and nuclear region. Thick disks and supermassive black holes can grow concurrently as a result of the violent instability. This chapter reviews the properties of high-redshift disk instabilities, the evolution of giant clumps and other features associated to the instability, and the resulting growth of bulges and associated sub-galactic components.

description: We present quasiparticle self-consistent GW (QSGW) calculations of semimetallic bulk Bi. We go beyond the conventional QSGW method by including the spin-orbit coupling throughout the self-consistency cycle. This approach improves the description of the electron and the hole pockets considerably with respect to standard density functional theory (DFT), leading to excellent agreement with experiment. We employ this relativistic QSGW approach to conduct a study of the semimetal-to-semiconductor and the trivial-to-topological transitions that Bi experiences under strain. DFT predicts that an unphysically large strain is needed for such transitions. We show, by means of the relativistic QSGW description of the electronic structure, that an in-plane tensile strain of only 0.3% and a compressive strain of 0.4% are sufficient to cause the semimetal-to-semiconductor and the trivial-to-topological phase transitions, respectively. Thus, the required strain moves into a regime that is likely to be realizable in experiment, which opens up the possibility to explore bulklike topological behavior of pure Bi.
Stationary Distribution Convergence for Generalized Jackson Networks in Heavy Traffic

Year: 2009

description: In a recent paper [5] it was shown that under suitable conditions stationary distributions of the (scaled) queue lengths process for a generalized Jackson network converge to the stationary distribution of the associated re ected Brownian motion in the heavy traffic limit. The proof relied on certain exponential integrability assumptions on the primitives of the network. In this note we show that the above result holds under much weaker integrability conditions. We provide an alternative proof of this result assuming (in addition to natural heavy traffic and stability assumptions) only standard independence and square integrability conditions on the network primitives that are commonly used in heavy traffic analysis. Furthermore, under additional integrability conditions we establish convergence of moments of stationary distributions.

We prove that, after an initial conformal change, the flow converges, in the Gromov-Hausdorff sense, to a torus with a flat Riemannian metric determined by the OT-manifolds themselves.

Variational Conditions Under the Constant Rank Constraint Qualification
Creators: name: Lu, Shu
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: This paper studies solution properties of a parametric variational condition under the constant rank constraint qualification (CRCQ), and properties of its underlying set. We start by showing that if the CRCQ holds at a point in a fixed set, then there exists a one-to-one correspondence between the collection of nonempty faces of the normal cone to the set at that point and the collection of active index sets at points nearby. We then study the behavior of the Euclidean projector, and prove under the CRCQ that the set of multipliers associated with the Euclidean projection is locally a continuous multifunction. Following that, we apply the degree theory to a localized normal map, to show that the combination of the CRCQ and the so-called strong coherent orientation condition suffices for the parametric variational condition to have a locally unique, continuous solution, which is selected from finitely many C1 functions. Applications of this result under additional assumptions extend or recover some earlier results on parametric variational inequalities.

description: In physical systems, decoherence can arise from both dissipative and dephasing processes. In mechanical resonators, the driven frequency response measures a combination of both, while time domain techniques such as ringdown measurements can separate the two. Here, we report the first observation of the mechanical ringdown of a carbon nanotube mechanical resonator. Comparing the mechanical quality factor obtained from frequency- and time-domain measurements, we find a spectral quality factor four times smaller than that measured in ringdown, demonstrating dephasing-induced decoherence of the nanomechanical motion. This decoherence is seen to arise at high driving amplitudes, pointing to a non-linear dephasing mechanism. Our results highlight the importance of time-domain techniques for understanding dissipation in nano-mechanical resonators, and the relevance of decoherence mechanisms in nanotube mechanics.
Impacts of agronomic practices on insect pest populations in quinoa

Subjects: Quinoa--Diseases and pests

description: Farming practices can be manipulated to increase crop yield, reduce pests, and suit production to different climates. However, management of newly introduced crops is difficult when pest complexes and their interactions with agronomic practices are unknown. Quinoa is a relatively new crop to North America, and little research has been done to identify insect pests and how they are impacted by management practices. Here, I demonstrate how several common agronomic practices influence insect pest population dynamics in quinoa in Washington State, USA. First, I identify the main pest complex of quinoa in Eastern WA. I found that Lygus spp. (Hemiptera: Miridae) and Aphis craccivora (Hemiptera: Aphididae) were the most abundant insect pests in the field in 2017 and 2018. I then assessed the effects of irrigation, planting method, and quinoa variety on the seasonal pest population dynamics of Lygus. Agronomic practices had a significant impact on pest abundance, but these effects varied among seasons. Both irrigation and direct seeding had reduced insect pests. Overall, the study shows that planting method and irrigation regime may be important components of pest control. Next, I characterized the impacts of organic and synthetic fertilizer and quinoa variety on pest population growth and survival. In cage settings, organically fertilized quinoa supported lower aphid and Lygus populations than quinoa grown with synthetic or no fertilizer. The quinoa variety Cherry Vanilla also had lower pest populations than variety Titicaca. These results suggest that fertilizer regime and variety may be an important tool in effective pest control, and growers should consider using organic fertilizer. My results indicate the importance of manipulating agronomic practices to reduce insect pest populations and influence their dynamics in new crops.

description: Innovative manufacturing methodologies offer opportunity to fabricate tapered composite laminates without layer terminations. However, the complex mechanical behaviour of tapered composite beams has yet to be studied. We introduce an accurate cost-efficient analytical method in line with Timoshenko theory to predict transverse stresses of composite laminated beams comprising orthotropic tapered layers under transverse loading, including pressure loads and transverse body forces. The transverse stress components are derived by introducing taper into the lamina constitutive relation followed by Cauchy stress equilibrium. The main conclusions of this study include: (i) transverse stresses are fully coupled with the internal forces and their derivatives; (ii) transverse stresses can be discontinuous through the thickness; (iii) Classical Laminate Theory underestimates transverse stress magnitudes of composite laminated beams. Results are validated with 2D and 3D solid-like finite element analyses inferring high levels of accuracy for the transverse stresses valid up to 8◦ of taper.

description: Given a complex domain $Ω$ and analytic functions $φ_1,\ldots,φ_n : Ω\to \mathbb{D}$, we give geometric conditions for $H^\infty(Ω)$ to be generated by functions of the form $g \circ φ_k$, $g \in H^\infty(\mathbb{D})$. We apply these results to the extension of bounded functions on an analytic one-dimensional complex subvariety of the polydisk $\mathbb{D}^n$ to functions in the Schur-Agler algebra of $\mathbb{D}^n$, with an estimate on the norm of the extension. Our proofs use some extension of the techniques of separation of singularities by Havin, Nersessian and Ortega-Cerdá.

Rescheduling-based congestion management using particle swarm optimization strategy

Publisher: name: figshare

Subjects: Electronics, sensors and digital hardware not elsewhere classified

description: In the deregulated environment, the transmission grids are used optimally. This utilization of the transmission system makes some lines congested due to the capacity constraints of the line. Congestion becomes a barrier of power trading and it affects the security of the power system. Congestion Management (CM) acts as a major issue that threatens the system security and it is a most difficult task for the system operators. This paper tries to introduce a novel optimization based CM model with advanced soft computing technique. An algorithm is introduced in this paper to deal with CM, which obviously optimize the generating power of added generators with the bus system. This manages the congestion with minimum rescheduling cost. The proposed optimization algorithm termed as Whale Optimization algorithm (WOA) involves in the management of congestion optimally. Subsequently, the experimentation is performed in the test bus system of 118 bus systems. The effectiveness of proposed model is compared with the conventional methods, with respect to cost and convergence.
A Numerical Scheme for Invariant Distributions of Constrained Diffusions

description: Reflected diffusions in polyhedral domains are commonly used as approximate models for stochastic processing networks in heavy traffic. Stationary distributions of such models give useful information on the steady state performance of the corresponding stochastic networks and thus it is important to develop reliable and efficient algorithms for numerical computation of such distributions. In this work we propose and analyze a Monte-Carlo scheme based on an Euler type discretization of the reflected stochastic differential equation using a single sequence of time discretization steps which decrease to zero as time approaches infinity. Appropriately weighted empirical measures constructed from the simulated discretized reflected diffusion are proposed as approximations for the invariant probability measure of the true diffusion model. Almost sure consistency results are established that in particular show that weighted averages of polynomially growing continuous functionals evaluated on the discretized simulated system converge a.s. to the corresponding integrals with respect to the invariant measure. Proofs rely on constructing suitable Lyapunov functions for tightness and uniform integrability and characterizing almost sure limit points through an extension of Echeverria’s criteria for reflected diffusions. Regularity properties of the underlying Skorohod problems play a key role in the proofs. Rates of convergence for suitable families of test functions are also obtained. A key advantage of Monte-Carlo methods is the ease of implementation, particularly for high dimensional problems. A numerical example of a eight dimensional Skorohod problem is presented to illustrate the applicability of the approach.

description: The Maunder minimum (MM) of greatly reduced solar activity took place in 1645-1715, but the exact level of sunspot activity is uncertain as based, to a large extent, on historical generic statements of the absence of spots on the Sun. Here we aim, using a conservative approach, to assess the level and length of solar cycle during the Maunder minimum, on the basis of direct historical records by astronomers of that time. A database of the active and inactive days (days with and without recorded sunspots on the solar disc respectively) is constructed for three models of different levels of conservatism (loose ML, optimum MO and strict MS models) regarding generic no-spot records. We have used the active day fraction to estimate the group sunspot number during the MM. A clear cyclic variability is found throughout the MM with peaks at around 1655--1657, 1675, 1684 and 1705, and possibly 1666, with the active day fraction not exceeding 0.2, 0.3 or 0.4 during the core MM, for the three models. Estimated sunspot numbers are found very low in accordance with a grand minimum of solar activity. We have found, for the core MM (1650-1700), that: (1) A large fraction of no-spot records, corresponding to the solar meridian observations, may be unreliable in the conventional database. (2) The active day fraction remained low (below 0.3-0.4) throughout the MM, indicating the low level of sunspot activity. (3) The solar cycle appears clearly during the core MM. (4) The length of the solar cycle during the core MM appears $9\pm 1$ years, but there is an uncertainty in that. (5) The magnitude of the sunspot cycle during MM is assessed to be below 5-10 in sunspot numbers; A hypothesis of the high solar cycles during the MM is not confirmed.

description: Let X be a quasiprojective smooth surface defined over an algebraically closed field of positive characteristic. In this note we show that if X is Frobenius split then so is the Hilbert scheme Hilbn(X) of n points in X. In particular, we get the higher cohomology vanishing for ample line bundles on Hilbn(X) when X is projective and Frobenius split.
