description: In the D = (n + m + 1) dimensional brane world scenario with m compact dimensions, the radion modulus can be stabilised by a massive bulk m-form antisymmetric field. We analyse some of the phenomenological aspects of this scenario. We find that the radion mass is smaller than the TeV scale, but larger than that in the case where the radion modulus is stabilised by a bulk scalar field. From the macroscopic n dimensional spacetime point of view, the m-form field mimics a set of p-form fields. We analyse the mass spectrum of these fields. The lowest mass is \stackrel{>}{_\sim} TeV whereas, for any bulk or brane field, the excitations in the compact space have Planckian mass and are likely to reintroduce the hierarchy problem. Also, we analyse the couplings of the m-form field to the matter fields living on a brane. The present results are applicable to more general cases also.

description: We study the dynamics of a scalar field Φwith the potential g(|Φ|^2-η^2)^2/2 (g=self-coupling constant, η=symmetry breaking scale) after inflation and make clear whether topological defects can ever be formed during preheating. In particular, we pay attention to GUT defects (η\sim 10^{15}GeV - 10^{17}GeV), and consider three types of fluctuations. The first one is produced due to parametric resonance, the second is due to the negative curvature of the potential, and the last is created during inflation. We search for the parameter region that nonthermal fluctuations of the scalar field produced through the parametric resonant decay of its homogeneous part do not lead to defect formation. We find that this region is rather wide, and the GUT defects are not produced after inflation. This fact shows that the positiveness of the effective mass square of the field and production of large fluctuations whose amplitude is as large as that of homogeneous mode are not enough conditions for full symmetry restoration.

description: Objective: The main objective of this article is to examine whether the Driving Anger Expression Inventory (DAX) applies to German drivers because this scale has previously been given to drivers in many different countries. Methods: We applied German versions of the DAX, the Driving Anger Scale (DAS), and the State-Trait Anger Expression Inventory (STAXI) to a sample of 501 German drivers. We computed confirmatory factor analysis and principal axis factoring (PAF) analysis to examine the structure of driving anger expression in Germany. Finally, we related the drivers’ anger exp ression scores to their driving anger experiences and their general anger propensities to assess the validity of the DAX for German drivers. Results: Results indicated that the DAX’s original factor structure does not apply to German drivers because the confirmatory factor analysis did not show a good model fit. An item analysis revealed that many DAX items had no meaningful variability. They were excluded from further analysis. The subsequent PAF analysis indicated that German drivers do not use personal physical aggression to express their driving anger. Instead, they reported unique preventive anger expression management behavior. In addition, their driving anger expressions were significantly related to their driving anger experiences and their general anger propensities indicated the validity of the refined DAX for German drivers. Conclusions: We conclude that German drivers do not use strong behaviors to express their driving anger. Many statements of Deffenbacher et al.’s (Behav Res Ther. 40:717–737, 2002) original American questionnaire were not applicable for our sample of German drivers. These findings are in line with several other studies showing discrepancies in driving anger expression in various countries. Future investigations should examine the reasons for discrepancies in driving anger expression.

description: In this work, we investigate the problem of simultaneously learning and controlling a system subject to adversarial choices of disturbances and system parameters. We study the problem for a scalar system with $l_\infty$-norm bounded disturbances and system parameters constrained to lie in a known bounded convex polytope. We present a controller that is globally stabilizing and gives continuously improving bounds on the worst-case state deviation. The proposed controller simultaneously learns the system parameters and controls the system. The controller emerges naturally from an optimization problem and balances exploration and exploitation in such a way that it is able to efficiently stabilize unstable and adversarial system dynamics. Specifically, if the controller is faced with large uncertainty, the initial focus is on exploration, retrieving information about the system by applying state-feedback controllers with varying gains and signs. In a pre-specified bounded region around the origin, our control strategy can be seen as passive in the sense that it learns very little information. Only once the noise and/or system parameters act in an adversarial way, leading to the state exiting the aforementioned region for more than one time-step, our proposed controller behaves aggressively in that it is guaranteed to learn enough about the system to subsequently robustly stabilize it. We end by demonstrating the efficiency of our methods via numerical simulations.

description: In this work, a method is proposed for increasing the operational properties of wood by treating it with organomineral compositions based on arabinogalactan and silica. Scots pine (Pinus silvestris L.) was chosen as the object of the study. Three different treatments were used. One treatment was a pure aqueous solution of arabinogalactan, the second and third were compositions based on aqueous solutions of arabinogalactan with 5% and 10% (by weight) addition of highly dispersed silica, respectively. Arabinogalactan was used as a surfactant for silica nanoparticles and also as a film-forming agent. The hardness of the wood surface increased by 1.2-2.3 times and compressive strength along the fibers increased by 20-45% after treatment with an organic-mineral composition. Treatment with impregnating compositions did not lead to a significant decrease in moisture absorption and swelling.

description: The overall structure of the transition state and intermediate ensembles experimentally observed for Dihydrofolate Reductase and Interleukin-1beta can be obtained utilizing simplified models which have almost no energetic frustration. The predictive power of these models suggest that, even for these very large proteins with completely different folding mechanisms and functions, real protein sequences are sufficiently well designed and much of the structural heterogeneity observed in the intermediates and the transition state ensembles is determined by topological effects.

description: Current wafer-scale fabrication methods for graphene-based electronics and sensors involve the transfer of single-layer graphene by a support polymer. This often leaves some polymer residue on the graphene, which can strongly impact its electronic, thermal, and mechanical resonance properties. To assess the cleanliness of graphene fabrication methods, it is thus of considerable interest to quantify the amount of contamination on top of the graphene. Here, we present a methodology for direct measurement of the mass of the graphene sheet using quartz crystal microbalances (QCM). By monitoring the QCM resonance frequency during removal of graphene in an oxygen plasma, the total mass of the graphene and contamination is determined with sub-graphene-monolayer accuracy. Since the etch-rate of the contamination is higher than that of graphene, quantitative measurements of the mass of contaminants below, on top, and between graphene layers are obtained. We find that polymer-based dry transfer methods can increase the mass of a graphene sheet by a factor of 10. The presented mass measurement method is conceptually straightforward to interpret and can be used for standardized testing of graphene transfer procedures in order to improve the quality of graphene devices in future applications.

description: We investigate the pricing of cliquet options in a jump-diffusion model. The considered option is of monthly sum cap style while the underlying stock price model is driven by a drifted Lévy process entailing a Brownian diffusion component as well as compound Poisson jumps. We also derive representations for the density and distribution function of the emerging Lévy process. In this setting, we infer semi-analytic expressions for the cliquet option price by two different approaches. The first one involves the probability distribution function of the driving Lévy process whereas the second draws upon Fourier transform techniques. With view on sensitivity analysis and hedging purposes, we eventually deduce representations for several Greeks while putting emphasis on the Vega.

Critical exponents for average quantities are calculated, first to lowest order and then to all orders, in $ε=D-2 - d/2$. In particular, it is found that $νd =2$. When D=d+1, this model is equivalent to a large N limit of the strongly commensurate dirty boson problem.

description: The rate of litter decomposition can vary within ecosystems that have high spatial heterogeneity, and many uncertainties remain regarding the abiotic and biotic factors that act as determinants of decomposition rates at small spatial scales. This study investigated the decomposition rates of leaves and fine roots of Croton sonderianus Mull. Arg., Poincianella pyramidalis Tul., and Aspidosperma pyrifolium Mart. over 12 months in a semiarid ecosystem in Brazil. Twelve biotic and abiotic factors were also evaluated as local determinants of decomposition rates. A 2000 × 500 m grid was delimited within which thirty 20 × 20 m plots were established. Two sets of litterbags were installed in each plot, one containing a mixture of leaves and the other a mixture of roots. The approximate mean lost mass was 90% for leaf material and 47% for roots after 10 and 12 months, respectively. Due to the litterbag incubation sites being distributed in a heterogeneous area, values for the intrinsic decay coefficient (k) (through month) varied widely from a minimum of 0.073 to a maximum of 0.458 for leaf litter and from 0.045 to 0.077 for roots. Variation in the decay coefficients for leaves and roots was significantly explained by aerial plant biomass and litterfall production, respectively; more open areas exhibited the highest rates of decomposition. Vegetation structure that favors the exposure of soil to solar radiation can influence the decomposition process, promoting an increase in leaf, and fine root decomposition rates at small spatial scales in tropical semiarid ecosystems.

description: In a recent breakthrough result, Chattopadhyay, Mande and Sherif [ECCC TR18-17] showed an exponential separation between the log approximate rank and randomized communication complexity of a total function $f$, hence refuting the log approximate rank conjecture of Lee and Shraibman [2009]. We provide an alternate proof of their randomized communication complexity lower bound using the information complexity approach. Using the intuition developed there, we derive a polynomially-related quantum communication complexity lower bound using the quantum information complexity approach, thus providing an exponential separation between the log approximate rank and quantum communication complexity of $f$. Previously, the best known separation between these two measures was (almost) quadratic, due to Anshu, Ben-David, Garg, Jain, Kothari and Lee [CCC, 2017]. This settles one of the main question left open by Chattopadhyay, Mande and Sherif, and refutes the quantum log approximate rank conjecture of Lee and Shraibman [2009]. Along the way, we develop a Shearer-type protocol embedding for product input distributions that might be of independent interest.

description: We analytically as well as numerically study the properties of one-dimensional holographic p- wave superconductors in the presence of backreaction. We employ the Sturm-Liouville eigenvalue problem for the analytical calculation and the shooting method for the numerical investigations. We apply the AdS3/CFT2 correspondence and determine the relation between the critical temperature Tc and the chemical potential μfor different values of mass m of charged spin-1 field and backreacting parameters. We observe that the data of both analytical and numerical studies are in good agreement. We find out that increasing the backreaction as well as the mass parameter cause the greater values for Tc/ μ. Therefore, it makes the condensation harder to form. In addition, the analytical and numerical approaches show that the value of the critical exponent βis 1/2 which is the same as in the mean field theory. Moreover, both methods confirm the exhibition of a second order phase transition.

description: Trapped ions are a versatile platform for the investigation of quantum many-body phenomena, in particular for the study of scenarios where long-range interactions are mediated by phonons. Recent experiments have shown that the trapped ion platform can be augmented by exciting high-lying Rydberg states. This introduces controllable state-dependent interactions that are independent from the phonon structure. However, the many-body physics in this newly accessible regime is largely unexplored. We show that this system grants access to generalized Dicke model physics, where dipolar interactions between ions in Rydberg states drastically alter the collective non-equilibrium behavior. We analyze and classify the emerging dynamical phases and identify a host of non-equilibrium signatures such as multi-phase coexistence regions and phonon-lasing regimes. We moreover show how they can be detected and characterized through the fluorescence signal of scattered photons. Our study thus highlights new capabilities of trapped Rydberg ion systems for creating and detecting quantum non-equilibrium phases.

description: The development of a new process for optimizing wind tunnel turning vanes for use in expanding corners is described. This process uses MATLAB tools to operate the infinite airfoil cascade solver MISES in order to take advantage of the powerful optimization tools already present in MATLAB. Airfoils are defined using four Bezier curves of fifth order to limit the number of design variables and take advantage of simple smoothness constraints. A parameter sweep is performed to verify the tool's operation and gain insight into the impacts of airfoil thickness, airfoil camber, cascade solidity, and expansion ratio before several optimization cases using various MATLAB optimization functions were used to show the ability of the optimizer to reduce total pressure loss and flow separation in turning vane cascades. Optimizer outputs were shown to reduce total pressure losses by up to 18% and separation magnitude by up to 53% over initial designs. Comparison with STAR-CCM+ models verified applicability of MISES cases to more accurate wind tunnel flows.

description: In this talk the gauge symmetry for Wilsonian flows in pure Yang-Mills theories is discussed. The background field formalism is used for the construction of a gauge invariant effective action. The symmetries of the effective action under gauge transformations for both the gauge field and the auxiliary background field are separately evaluated. Modified Ward-Takahashi and background field identities are used in my study. Finally it is shown how the symmetry properties of the full theory are restored in the limit where the cut-off is removed.

description: Wildland fire spread is typically described as a function of fuel, weather, and topography. An understanding of how these parameters are interrelated can help to close the gap on our understanding of the flame spread process. Fire spread over steep slopes is unique because the flame dramatically transitions from a detached, “plume” mode to an attached “boundary layer” mode at what appears to be a critical angle. The change in flame shape significantly increases the rate of spread by increasing the length and magnitude of heating ahead of the burning region. This attachment behavior has been observed in the literature, however the correlation between fire intensity, slope, wind, and flame shape is not yet well described or in a form which allows for prediction of fire behavior. A series of experiments using stationary gas burners have been undertaken to describe the behavior of a steady flame at multiple slopes under both wind and non-wind conditions. A stationary gas burner has been used to emulate flames under various fire intensities, burner aspect ratios, slopes, and wind conditions. A small-scale apparatus was first used to image hot gases using a shadowgraph technique coupled with downstream temperature measurements. Later a larger-scale apparatus was used with downstream temperature measurements to determine instantaneous downstream heating lengths. Both steady and time-dependent analysis of the attachment process is presented, along with its relation to fire spread. Based on the observed trends from these relationships non-dimensional parameters are introduced to relate the effects of inclination, wind, fire size and aspect ratio to the length of the heating region ahead of the burner. It is proposed that this value may be useful as a simple way to incorporate these effects in a wildland fire spread model.

description: Security is the most critical aspect today in distributed computations. Grid computing shares and use resources in dynamic distributed environments. The dynamic nature of Grid environments results in security concerns in high performance applications. Almost all the communications in this distributed sharing environment are done using basic and standard cryptographic algorithms. But these algorithms do not provide the required security. Hence there is a need of new, strong and reliable technical approaches to solve these challenges.This paper analyzes the GUI Grid toolkit – SCADY (Scady & Dynamic) which is designed by the authors, describesvarious security approaches and proposes the security mechanism for tasks of SCADY based on the X.509 certification so that high performance applications can be catered.

description: Considering a possibility that the pseudogap state in the underdoped high-$T_{c}$ superconductors is not due to a superconducting correlation, we study the tunneling spectroscopy below $T_{c}$ based on the phenomenological models of the pseudogap state. Specifically we consider two cases: (1) the pseudogap is a simple suppression of the density of states with an unknown origin; (2) the pseudogap state is due to an antiferromagnetic correlation. For both cases we calculate $dI/dV$ using the BTK theory. The results are discussed in comparison with experiments.

description: We extend our framework for the simultaneous resummation of soft and small-mass logarithms to rapidity distributions in top quark pair production. We give numerical results for the rapidity distribution of the top quark or the anti-top quark, as well as the rapidity distribution of the $t\bar{t}$ pair, finding that resummation effects stabilize the dependence of the differential cross sections on the choice of factorization scale. We compare our results with recent measurements at the Large Hadron Collider and find good agreement. Our results may be useful in the extraction of the gluon parton distribution function from $t\bar{t}$ production.

Flowfield Estimation and Vortex Stabilization near an Actuated Airfoil

description: Feedback control of unsteady flow structures is a challenging problem that is of interest for the creation of agile bio-inspired micro aerial vehicles. This thesis presents two separate results in the estimation and control of unsteady flow structures: the application of a principled estimation method that generates full flowfield estimates using data obtained from a limited number of pressure sensors, and the analysis of a nonlinear control system consisting of a single vortex in a freestream near an actuated cylinder and an airfoil. The estimation method is based on Dynamic Mode Decompositions (DMD), a data-driven algorithm that approximates a time series of data as a sum of modes that evolve linearly. DMD is used here to create a linear system that approximates the flow dynamics and pressure sensor output from Particle Image Velocimetry (PIV) and pressure measurements of the flowfield around the airfoil. A DMD Kalman Filter (DMD-KF) uses the pressure measurements to estimate the evolution of this linear system, and thus produce an approximation of the flowfield from the pressure data alone. The DMD-KF is implemented for experimental data from two different setups: a pitching cambered ellipse airfoil and a surging NACA 0012 airfoil. Filter performance is evaluated using the original flowfield PIV data, and compared with a DMD reconstruction. For control analysis, heaving and/or surging are used as input to stabilize the vortex position relative to the body. The closed-loop system utilizes a linear state-feedback control law. Conditions on the control gains to stabilize any of the equilibrium points are determined analytically for the cylinder case and numerically for the airfoil. Simulations of the open- and closed-loop systems illustrate the bifurcations that arise from varying the vortex strength, bound circulation and/or control gains.

Non-ideal rheology of semidilute bacterial suspensions

description: The rheology of semidilute bacterial suspensions is studied with the tools of kinetic theory, considering binary interactions, going beyond the ideal gas approximation. Two models for the interactions are considered, which encompass both the steric and short range interactions. In these, swimmers can either align polarly regardless of the state previous to the collision or they can align axially, being possible the end up antiparallel if the relative angle between directors is large. In both cases, it is found that an ordered phase develops when increasing the density, where the shear stress oscillates with large amplitudes, when a constant shear rate is imposed. This oscillation disappears for large shear rates in a continuous or discontinuous transition, depending if the aligning is polar or axial, respectively. For pusher swimmers these non-linear effects can produce an increase on the shear stress, contrary to the prediction of viscosity reduction made for the dilute regime with the ideal gas approximation.
