description: Phosphorene is an anisotropic puckered two-dimensional ($2$D) hexagonal lattice of phosphorus atoms. The edge modes in a zigzag phosphorene nanoribbon (ZPNR) are quasi-flat in nature and fully isolated from the bulk states, which are unique in comparison to the other hexagonal lattices like graphene, silicene etc. We theoretically investigate the Ruderman-Kittel-Kasuya-Yosida (RKKY) exchange interaction between two magnetic impurities placed on the nanoribbon, and extract the signatures of the flat edge states via the behavior of it. Due to the complete separation of the edge states from the bulk, we can isolate the edge mode contribution via the RKKY interaction from that of the bulk by tuning the external gate potential when both the impurities are placed at the same edge. The bulk induced RKKY interaction exhibits very smooth oscillation with the distance between the two impurities, whereas for edge modes it fluctuates very rapidly. We also explore the effect of tensile strain both in absence and presence of gate voltage and reveal that the RKKY interaction strength can be boosted under suitable doping, when both the impurities are within the bulk.

description: With the proliferation of renewable energy sources, there has been a growing interest in battery chemistries for grid scale energy storage. Aqueous sodium ion batteries are particularly interesting for large scale energy storage because of their low cost and high safety, however, they tend to show poor long term stability. NaTi2(PO4)3 shows promise as an anode for these systems with excellent long term stability when cycled quickly. When cycled slowly, NaTi2(PO4)3 shows rapid capacity fade. The reasons for this rate depend capacity fade is poorly understood and is the topic of this document. It has been found that the products of the hydrogen evolution reaction, H2(g) and OH-, are the two largest contributors to capacity fade. High electrolyte pH caused by generation of OH- promotes dissolution of NTP during extend cycling, this is exacerbated when the pH increase above 11. The single greatest cause of apparent capacity fade for this material is loss of electrochemical surface area due to hydrogen gas entrapment within the porous structure of the electrode. Capacity lost in this manner can be recovered through reinfiltration of the electrode. The detrimental effects of gas entrapment within the electrode can be partially mitigated through compositing of the electrode with activated carbon and enhancing the wettability of the pores through addition of a surfactant to the electrolyte.

description: This paper presents an R package to handle and represent measurements with errors in a very simple way. We briefly introduce the main concepts of metrology and propagation of uncertainty, and discuss related R packages. Building upon this, we introduce the 'errors' package, which provides a class for associating uncertainty metadata, automated propagation and reporting. Working with 'errors' enables transparent, lightweight, less error-prone handling and convenient representation of measurements with errors. Finally, we discuss the advantages, limitations and future work of computing with errors.

description: What do you think of when you hear the term 'open science'? And what do practice-based arts researchers think? Might these researchers feel ignored? In parallel, John Kampfner (2017) notes that the UK's creative industries contribute almost £90 billion net to GDP – and yet policy makers appear not to understand the link between arts education and economic success. Is the world of repositories and open access guilty of making the same mistake? DARIAH-EU thinks so, responding to the announcement of Plan S (where the 'S' stands for science) as revealing 'a strong bias toward the STEM perspective' (DARIAH-EU, 2018, p.1). The term open science 'may seem alienating' (ibid.) to arts researchers whilst Peter Suber (2018) notes it's a phrase which is 'needlessly confusing'. For practice-based arts researchers, this alienation also manifests itself in repositories which are predominantly designed for traditional text-based outputs; depositing their 'nuanced, layered [and] ambiguous' outputs(Meece, Robinson and Gramstadt, 2017, p.211) can seem like putting a square peg in a round hole. So how can we make repositories work better for arts researchers, and avoid a gaping hole developing in the open access (OA) landscape?

description: The Polyakov's "soldering procedure" which shows how two-dimensional diffeomorphisms can be obtained from SL(2,R) gauge transformations is discussed using the free-field representation of SL(2,R) current algebra. Using this formalism, the relation of Polyakov's method to that of the Hamiltonian reduction becomes transparent. This discussion is then generalised to N=1 superdiffeomorphisms which can be obtained from N=1 super Osp(1,2) gauge transformations. It is also demonstrated that the phase space of the Osp(2,2) supercurrent algebra represented by free superfields is connected to the classical phase space of N=2 superconformal algebra via Hamiltonian reduction.}

Light Scattering by Fractal Dust Aggregates. II. Opacity and Asymmetry Parameter

Year: 2018
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: Optical properties of dust aggregates are important at various astrophysical environments. To find a reliable approximation method for optical properties of dust aggregates, we calculate the opacity and the asymmetry parameter of dust aggregates by using a rigorous numerical method, the T-Matrix Method (TMM), and then the results are compared to those obtained by approximate methods; the Rayleigh-Gans-Debye (RGD) theory, the effective medium theory (EMT), and the distribution of hollow spheres method (DHS). First of all, we confirm that the RGD theory breaks down when multiple scattering is important. In addition, we find that both EMT and DHS fail to reproduce the optical properties of dust aggregates with fractal dimension of 2 when the incident wavelength is shorter than the aggregate radius. In order to solve these problems, we test the mean field theory (MFT), where multiple scattering can be taken into account. We show that the extinction opacity of dust aggregates can be well reproduced by MFT. However, it is also shown that MFT is not able to reproduce the scattering and absorption opacities when multiple scattering is important. We successfully resolve this weak point of MFT, by newly developing a modified mean field theory (MMF). Hence, we conclude that MMF can be a useful tool to investigate radiative transfer properties of various astrophysical environments. We also point out an enhancement of the absorption opacity of dust aggregates in the Rayleigh domain, which would be important to explain the large millimeter-wave opacity inferred from observations of protoplanetary disks.

Abundance variations and first ionization potential trends during large stellar flares
Creators: name: Nordon, R.
name: Behar, E.
Publisher: name: arXiv
Year: 2007

subject: FOS: Physical sciences

description: The Solar First Ionization Potential (FIP) effect, where low-FIP elements are enriched in the corona relative to the photosphere, while high-FIP abundances remain unchanged, has been known for a long while. High resolution X-ray spectroscopy has revealed that active stellar coronae show an opposite effect, which was labeled the Inverse-FIP (IFIP) effect. The correlation found between coronal activity and the FIP/IFIP bias suggested perhaps that flaring activity is involved in switching from FIP to IFIP. This work aims at a more systematic understanding of the FIP trends during stellar flares and complements an earlier study based on Chandra alone. The eight brightest X-ray flares observed with XMM-Newton are analyzed and compared with their respective quiescence states. Together with six previous flares observed with Chandra, this establishes the best currently available sample of flares. We look for abundance variations during the flare and their correlation with FIP. For that purpose, we define a new FIP bias measure. A trend is found where coronae that are IFIP biased in quiescence, during flares show a FIP bias with respect to their quiescence composition. This effect is reversed for coronae that are FIP biased in quiescence. The observed trend is thus consistent with chromospheric evaporation rather than with a FIP mechanism operating during flares. It also suggests that the quiescent IFIP bias is real and that the large flares are not the direct cause of the IFIP effect in stellar coronae.

description: This thesis describes the design and use of nanofillers (NFs) synthesized by surface-initiated atom transfer radical polymerization (SI-ATRP). The history of polymer/inorganic (hybrid) nanocomposites (NCs), the development and fundamentals of SI-ATRP are discussed in the introductory chapter. Chapters II and III present the major challenges in SI-ATRP, including the surface confinement effect that influences the polymerization kinetics and unavoidable termination reactions that limit the molecular weight of polymers tethered on surfaces. Chapter II discusses the experiments that demonstrate the surface confinement effects which were found to be a minor contributor to controlled chain growth in normal SI-ATRP, with one exception, when one attempts to polymerize sterically bulky and hydrophilic monomers. Chapter III discusses ways to suppress termination reactions that contribute to molecular weight limitations by carrying out the reactions under high-pressure, high-dilution, or/and at high-temperature. In addition to extend the fundamental understanding and improvements of SI-ATRP, Chapters IV and V discuss the use of NFs to create novel nanostructured functional materials. Chapter IV focuses on the preparation of traditional filler-matrix composites. Mechanically and thermally stable films with silica nanoparticle (SiO2) filler loadings up to 70 wt% were achieved by introducing enthalpy interactions to improve the dispersibility of SiO2 in a selected matrix. Chapter V presents approaches that allow preparation of a procesesable self-assembled film of hybrid NCs that do not require blending with a host matrix. This class of material was created by NF self-assembly and interparticle brush entanglement which provided uniform NF dispersion in a monolayer film with zero aggregation, as observed by transmission electron microscopy. Chapter VI, VII, and VIII further expands the scope of materials designed in Chapter IV and V. Chapter VI specifically studies the structure-properties relationship of the particle-brush composites and the confirmation that controls the polymer conformation and interface strength which are the keys for various enhanced properties. Chapter VII discusses the effects of thermal self-initiation of styrene (S) on the properties of particle-brush materials. Chapter VIII discusses the use of particle-brush hybrid particles to synthesize porous nanocarbons.

description: Since Viking has conducted its life detection experiments on Mars, many missions have enhanced our knowledge about the environmental conditions on the Red Planet. However, the Martian surface chemistry and the Viking lander results remain puzzling. Non-biological explanations that favor a strong inorganic oxidant are currently favored (e.g., Mancinelli, 1989; Quinn and Zent, 1999; Klein, 1999, Yen et al., 2000), but problems remain regarding the life time, source, and abundance of that oxidant to account for the Viking observations (Zent and McKay, 1994). Alternatively, a hypothesis favoring the biological origin of a strong oxidizer has recently been advanced (Houtkooper and Schulze-Makuch, 2007). Here, we report about laboratory experiments that simulate the experiments to be conducted by the Thermal and Evolved Gas Analyzer (TEGA) instrument of the Phoenix lander, which is to descend on Mars in May 2008. Our experiments provide a baseline for an unbiased test for chemical versus biological responses, which can be applied at the time the Phoenix Lander transmits its first results from the Martian surface.

These domain walls are predicted to support counterpropogating topologically protected helical (TPH) edge states when the AB and BA regions are gapped. We fabricate designer moir{é} crystals with wavelengths longer than 50 nm and demonstrate the emergence of TPH states on the domain wall network by scanning tunneling spectroscopy measurements. We observe a double-line profile of the TPH states on the domain walls, only occurring when the AB and BA regions are gapped. Our results demonstrate a practical and flexible method for TPH state network construction.

description: Inertial cavitation in soft matter is an important phenomenon featured in a wide array of biological and engineering processes. Recent advances in experimental, theoretical, and numerical techniques have provided access into a world full of nonlinear physics, yet most of our quantitative understanding to date has been centered on a spherically symmetric description of the cavitation process. However, cavitation bubble growth and collapse rarely occur in a perfectly symmetrical fashion, particularly in soft materials. Predicting the onset of dynamically arising, non-spherical instabilities has remained a significant, unresolved challenge in part due to the additional constitutive complexities introduced by the surrounding nonlinear viscoelastic solid. Here, we provide a new theoretical model capable of accurately predicting the onset of non-spherical instability shapes of a bubble in a soft material by explicitly accounting for all pertinent nonlinear interactions between the fluid-like cavitation bubble and the solid-like surroundings. Comparison against high-resolution experimental images from laser-induced cavitation events in a polyacrylamide (PA) hydrogel show excellent agreement. Interestingly, and consistent with experimental findings, our model predicts the emergence of various dynamic instability shapes for hoop stretch ratios greater than one in contrast to most quasi-static investigations. Our new theoretical framework not only provides unprecedented insight into the cavitation dynamics in a soft solid, but it also provides a quantitative means of interpreting bubble dynamics relevant to a wide array of engineering and medical applications as well as natural phenomena.

description: Pulsar glitches provide a unique way to study neutron star microphysics because short post-glitch dynamics are directly linked to strong frictional processes on small scales. To illustrate this connection between macroscopic observables and microphysics, we review calculations of vortex interactions focusing on Kelvin wave excitations and determine the corresponding mutual friction strength for realistic microscopic parameters in the inner crust. These density-dependent crustal coupling profiles are combined with a simplified treatment of the core coupling and implemented in a three-component neutron star model to construct a predictive framework for glitch rises. As a result of the density-dependent dynamics, we find the superfluid to transfer angular momentum to different parts of the crust and the core on different timescales. This can cause the spin frequency change to become non-monotonic in time, allowing for a maximum value much larger than the measured glitch size, as well as a delay in the recovery. The exact shape of the calculated glitch rise is strongly dependent on the relative strength between the crust and core mutual friction, providing the means to probe not only the crustal superfluid but also the deeper neutron star interior. To demonstrate the potential of this approach, we compare our predictive model with the first pulse-to-pulse observations recorded during the December 2016 glitch of the Vela pulsar. Our analysis suggests that the glitch rise behavior is relatively insensitive to the crustal mutual friction strength as long as $\mathcal{B} \gtrsim 10^{-3}$, while being strongly dependent on the core coupling strength, which we find to be in the range $3 \times 10^{-5} \lesssim \mathcal{B}_{\rm core} \lesssim 10^{-4}$.

description: A two-boson realization of the second hamiltonian structure for the KP hierarchy has recently appeared in the literature. Furthermore, it has been claimed that this is also a realization of the hierarchy itself. This is surprising because it would mean that the dynamics of the KP hierarchy---which in its usual formulation requires an infinite number of fields---can be described with only two. The purpose of this short note is to point out the almost obvious fact that the hierarchy described by the two bosons is not the KP hierarchy but rather a reduction thereof---one which is moreover incompatible with the reduction to the KdV-type subhierarchies.

description: Cosmological phase transitions proceed via the nucleation of bubbles that subsequently expand and collide. The resulting gravitational wave spectrum depends crucially on the bubble wall velocity. Microscopic calculations of this velocity are challenging even in weakly coupled theories. We use holography to compute the wall velocity from first principles in a strongly coupled, non-Abelian, four-dimensional gauge theory. The wall velocity is determined dynamically in terms of the nucleation temperature. We find an approximately linear relation between the velocity and the ratio $Δ\mathcal{P}/\mathcal{E}$, with $Δ\mathcal{P}$ the pressure difference between the inside and the outside of the bubble and $\mathcal{E}$ the energy density outside the bubble. Up to a rescaling, the wall profile is well approximated by that of an equilibrium, phase-separated configuration at the critical temperature. We verify that ideal hydrodynamics provides a good description of the system everywhere except near the wall.

description: This dissertation studies multi-agent algorithms for learning Nash equilibrium strategies in games with many players. We focus our study on a set of learning dynamics in which agents seek to myopically optimize their next-stage utility given some forecast of opponent behavior; i.e., players act according to myopic best response dynamics. The prototypical algorithm in this class is the well-known fictitious play (FP) algorithm. FP dynamics are intuitively simple and can be seen as the \natural" learning dynamics associated with the Nash equilibrium concept. Accordingly, FP has received extensive study over the years and has been used in a variety of applications. Our contributions may be divided into two main research areas. First, we study fundamental properties of myopic best response (MBR) dynamics in large-scale games. We have three main contributions in this area. (i) We characterize the robustness of MBR dynamics to a class of perturbations common in real-world applications. (ii) We study FP dynamics in the important class of large-scale games known as potential games. We show that for almost all potential games and for almost all initial conditions, FP converges to a pure-strategy (deterministic) equilibrium. (iii) We develop tools to characterize the rate of convergence of MBR algorithms in potential games. In particular, we show that the rate of convergence of FP is \almost always" exponential in potential games. Our second research focus concerns implementation of MBR learning dynamics in large-scale games. MBR dynamics can be shown, theoretically, to converge to equilibrium strategies in important classes of large-scale games (e.g., potential games). However, despite theoretical convergence guarantees, MBR dynamics can be extremely impractical to implement in large games due to demanding requirements in terms of computational capacity, information overhead, communication infrastructure, and global synchronization. Using the aforementioned robustness result, we study practical methods to mitigate each of these issues. We place a special emphasis on studying algorithms that may be implemented in a network-based setting, i.e., a setting in which inter-agent communication is restricted to a (possibly sparse) overlaid communication graph. Within the network-based setting, we also study the use of so-called \inertia" in MBR algorithms as a tool for learning pure-strategy NE.

description: In this paper, we first introduce a new notion of canonical convolution operator, and show that it satisfies the commutative, associative, and distributive properties, which may be quite useful in signal processing. Moreover, it is proved that the generalized convolution theorem and generalized Young's inequality are also hold for the new canonical convolution operator associated with the LCT. Finally, we investigate the sufficient and necessary conditions for solving a class of convolution equations associated with the LCT.

Computational Complexity of interacting electrons and fundamental limitations of Density Functional Theory

Year: 2007

description: One of the central problems in quantum mechanics is to determine the ground state properties of a system of electrons interacting via the Coulomb potential. Since its introduction by Hohenberg, Kohn, and Sham, Density Functional Theory (DFT) has become the most widely used and successful method for simulating systems of interacting electrons, making their original work one of the most cited in physics. In this letter, we show that the field of computational complexity imposes fundamental limitations on DFT, as an efficient description of the associated universal functional would allow to solve any problem in the class QMA (the quantum version of NP) and thus particularly any problem in NP in polynomial time. This follows from the fact that finding the ground state energy of the Hubbard model in an external magnetic field is a hard problem even for a quantum computer, while given the universal functional it can be computed efficiently using DFT. This provides a clear illustration how the field of quantum computing is useful even if quantum computers would never be built.

Multi-Scale Modeling of Mechanical Properties of Single Wall Carbon Nanotube (SWCNT) Networks

description: Single wall carbon nanotubes (SWCNTs) show a variety of unparalleled properties such as high electrical and thermal conductivity, high specific surface area (SSA) and a large stiffness under axial loads. One of the major challenges in tapping the vast potential of SWCNTs is to fabricate nanotube based macrostructures that retain the unique properties of nanotubes. Pristine SWCNT aerogels are highly porous, isotropic structures of nanotubes mediated via van der Waals (VDW) interactions at junctions. The mechanical behavior of such aerogels is examined in several experimental studies. However, it is necessary to supplement these studies with insights from simulations in order to develop a fundamental understanding of deformation behavior of SWCNT aerogels. In this study, the mechanical behavior of SWCNT networks is studied using a multi-scale modeling approach. The mechanics of an individual nanotube and interactions between few nanotubes are modeled using molecular dynamics (MD) simulations. The results from atomistic simulations are used to inform meso-scale and continuum scale finite element (FE) models. The deformation mechanism of pristine SWCNT networks under large compressive strain is deduced from insights offered by meso-scale simulations. It is found that the elasticity of such networks is governed by the bending deformation of nanotubes while the plastic deformation is governed by the VDW interactions between nanotubes. The stress response of the material in the elastic regime is dictated by the VDW stresses on nanotubes while in the plastic regime, both the VDW and axial deformation stresses on nanotubes drive the overall stress response. In this study, the elastic behavior of a random SWCNT network with any set of junction stiffness and network density is also investigated using FE simulations. It is found that the elastic deformation of such networks can be governed either by the deformation of the nanotubes (bending, axial compression) or deformation of the junctions. The junction stiffness and the network density determine the network deformation mode. The results of the FE study are also applicable to any stiff fiber network.

description: We show that, the lattice regularization of chiral gauge theories proposed by Kaplan, when applied to a (2+1)-dimensional domain wall, produces a (1+1)-dimensional theory at low energy even if gauge anomaly produced by chiral fermions does not cancel.

description: We compute the baryon asymmetry created in a tachyonic electroweak symmetry breaking transition, focusing on the dependence on the source of effective CP-violation. Earlier simulations of Cold Electroweak Baryogenesis have almost exclusively considered a very specific CP-violating term explicitly biasing Chern-Simons number. We compare four different dimension six, scalar-gauge CP-violating terms, involving both the Higgs field and another dynamical scalar coupled to SU(2) or U(1) gauge fields. We find that for sensible values of parameters, all implementations can generate a baryon asymmetry consistent with observations, showing that baryogenesis is a generic outcome of a fast tachyonic electroweak transition.

Multiple-Cue Object Recognition for Interactionable Objects
Creators: name: Aboutalib, Sarah
Publisher: name: Figshare

Subjects: subject: 89999 Information and Computing Sciences not elsewhere classified
subject: FOS: Computer and information sciences

description: Category-level object recognition is a fundamental capability for the potential
use of robots in the assistance of humans in useful tasks. There have been
numerous vision-based object recognition systems yielding fast and accurate
results in constrained environments. However, by depending on visual cues,
these techniques are susceptible to object variations in size, lighting, rotation,
and pose, all of which cannot be avoided in real video data. Thus, the task of
object recognition still remains very challenging.

My thesis work builds upon the fact that robots can observe humans interacting
with the objects in their environment. We refer to the set of objects,
which can be involved in the interaction as `interactionable' objects. The interaction
of humans with the `interactionable' objects provides numerous nonvisual
cues to the identity of objects.

In this thesis, I will introduce a
flexible object recognition approach called
Multiple-Cue Object Recognition (MCOR) that can use multiple cues of any
predefined type, whether they are cues intrinsic to the object or provided by
observation of a human.
In pursuit of this goal, the thesis will provide several contributions: A representation
for the multiple cues including an object definition that allows for
the
flexible addition of these cues; Weights that reflect the various strength
of association between a particular cue and a particular object using a probabilistic
relational model, as well as object displacement values for localizing
the information in an image; Tools for defining visual features, segmentation,
tracking, and the values for the non-visual cues; Lastly, an object recognition
algorithm for the incremental discrimination of potential object categories.

We evaluate these contributions through a number of methods including
simulation to demonstrate the learning of weights and recognition based on an
analytical model, an analytical model that demonstrates the robustness of the
MCOR framework, and recognition results on real video data using a number
of datasets including video taken from a humanoid robot (Sony QRIO), video
captured from a meeting setting, scripted scenarios from outside universities,
and unscripted TV cooking data.

Using the datasets, we demonstrate the basic features of the MCOR algorithm
including its ability to use multiple cues of different types. We demonstrate
the applicability of MCOR to an outside dataset. We show that MCOR
has better recognition results over vision-only recognition systems, and show
that performance only improves with the addition of more cue types.
Topological phase transition and $\mathbb{Z}_2$ index for $S=1$ quantum spin chains

description: We study $S=1$ quantum spin systems on the infinite chain with short ranged Hamiltonians which have certain rotational and discrete symmetry. We define a $\mathbb{Z}_2$ index for any gapped unique ground state, and prove that it is invariant under smooth deformation. By using the index, we provide the first rigorous proof of the existence of a "topological" phase transition, which cannot be characterized by any conventional order parameters, between the AKLT ground state and trivial ground states. This rigorously establishes that the AKLT model is in a nontrivial symmetry protected topological phase.
