description: We present models representing the scattering of quasar radiation off free electrons and dust grains in geometries that approximate the structure of quasar host galaxies. We show that, for reasonable assumptions, scattering alone can easily produce ratios of nuclear (point source) to extended fluxes comparable to those determined in studies of quasar hosts. This result suggests that scattered quasar light, as well as stellar emission from the host galaxy, contributes significantly to the detected extended flux, leading to uncertainty in the inferred properties of quasar host. A significant contribution from scattered quasar light will lead to overestimates of the luminosity and hence mass of the host galaxy, and may also distort its morphology. Scattering of quasar light within the host galaxy may provide alternative explanations for the apparent peak in host luminosity at z = 2-3; possibly the overall average higher luminosity of radio-loud host galaxies relative to those of radio-quiet quasars (RQQs), and the apparent preference of high-luminosity RQQs for spheroidal rather than disk galaxies.

description: We discuss the results of calculations of the shear viscosity and thermal conductivity of pure neutron matter, carried out within the Landau-Abrikosov-Khalatnikov formalism. The probability of neutron-neutron collisions in the nuclear medium has been obtained from a realistic potential, using both the correlated basis function and the $G$-matrix approach. The results of our work indicate that medium modifications of nucleon-nucleon scattering are large, their inclusion leading to a dramatic enhancement of the transport coefficients. On the other hand, the results obtained from the two theoretical schemes appear to be in fairly good agreement.

A possible Efimov trimer state in a 3-component lithium-6 mixture

description: We consider the Efimov trimer theory as a possible framework to explain recently observed losses by inelastic three-body collisions in a three-hyperfine-component ultracold mixture of lithium 6. Within this framework, these losses would arise chiefly from the existence of an Efimov trimer bound state below the continuum of free triplets of atoms, and the loss maxima (at certain values of an applied magnetic field) would correspond to zero-energy resonances where the trimer dissociates into three free atoms. Our results show that such a trimer state is indeed possible given the two-body scattering lengths in the three-component lithium mixture, and gives rise to two zero-energy resonances. The locations of these resonances appear to be consistent with observed losses.

description: Background—Successful mechanical embolectomy for acute embolic arterial occlusion in the posteriorcerebral circulation can potentially result in less neurologic disability and mortality. The transradialapproach can potentially offer more direct navigation into the posterior circulation than the transfemoralapproach and can result in faster recanalization time.Objective—To compare procedural metrics and the technical and clinical outcomes of transradial versustransfemoral access for mechanical embolectomy in the posterior cerebral circulation.Material and Methods—Single-center retrospective review of a prospectively maintained neurointerven‐tional database from a large volume neurointerventional service in a tertiary academic center. Patients pre‐senting with acute disabling symptoms due to embolic occlusion of a large intracranial artery in the poste‐rior that underwent to endovascular treatment in our institution from January 2017 to January 2019 wereincluded in the present study.Results—Between January 2018 and January 2019 a total of 10 subjects underwent a mechanical embo‐lectomy for acute embolic occlusion on the posterior circulation via transradial access; and between Janu‐ary 2017 and January 2018 a total of 10 subjects underwent a mechanical embolectomy for acute embolicocclusion on the posterior circulation via transfemoral access. Subjects in the transradial access group had ashorter skin puncture to recanalization time compared to the transfemoral group (29.2 ± 17.6 in the transra‐dial group vs. 63.9 ± 56.7 in the transfemoral group respectively).

description: We describe a general analysis package for supernova (SN) light curves, called SNANA, that contains a simulation, light curve fitter, and cosmology fitter. The software is designed with the primary goal of using SNe Ia as distance indicators for the determination of cosmological parameters, but it can also be used to study efficiencies for analyses of SN rates, estimate contamination from non-Ia SNe, and optimize future surveys. Several SN models are available within the same software architecture, allowing technical features such as K-corrections to be consistently used among multiple models, and thus making it easier to make detailed comparisons between models. New and improved light-curve models can be easily added. The software works with arbitrary surveys and telescopes and has already been used by several collaborations, leading to more robust and easy-to-use code. This software is not intended as a final product release, but rather it is designed to undergo continual improvements from the community as more is learned about SNe. Below we give an overview of the SNANA capabilities, as well as some of its limitations. Interested users can find software downloads and more detailed information from the manuals at http://www.sdss.org/supernova/SNANA.html .

description: We present a family of robust tracer mass estimators to compute the enclosed mass of galaxy haloes from samples of discrete positional and kinematical data of tracers, such as halo stars, globular clusters and dwarf satellites. The data may be projected positions, distances, line of sight velocities or proper motions. Forms of the estimator tailored for the Milky Way galaxy and for M31 are given. Monte Carlo simulations are used to quantify the uncertainty as a function of sample size. For the Milky Way, the satellite sample consists of 26 galaxies with line-of-sight velocities. We find that the mass of the Milky Way within 300 kpc is ~ 0.9 x 10^12 solar masses assuming velocity isotropy. However, the mass estimate is sensitive to the anisotropy and could plausibly lie between 0.7 - 3.4 x 10^12 solar masses. Incorporating the proper motions of 6 Milky Way satellites into the dataset, we find ~ 1.4 x 10^12 solar masses. The range here if plausible anisotropies are used is still broader, from 1.2 - 2.7 x 10^12 solar masses. For M31, there are 23 satellite galaxies with measured line-of-sight velocities, but only M33 and IC 10 have proper motions. We use the line of sight velocities and distances of the satellite galaxies to estimate the mass of M31 within 300 kpc as ~ 1.4 x 10^12 solar masses assuming isotropy. There is only a modest dependence on anisotropy, with the mass varying between 1.3 -1.6 x 10^12 solar masses. Given the uncertainties, we conclude that the satellite data by themselves yield no reliable insights into which of the two galaxies is actually the more massive.

description: We consider N=2 supergravity in four dimensions with small R^2 curvature corrections. We construct large charge non-extremal black hole solutions in all space, with either a supersymmetric or a non-supersymmetric extremal limit, and analyze their thermodynamic properties. This generalizes some of the extremal solutions presented in [arXiv:0902.0831]. The indexed entropy of the non-extremal extension of the supersymmetric black hole, has the form of the extremal entropy, with the charges replaced by a function of the charges, the moduli at infinity and the non-extremality parameter. This is the same behavior as in the case without R^2-terms.

The replacement basis of depreciation in the regulation of rates of privately owned utilities
Creators: name: Lee, Ming Chong
Publisher: name: University of British Columbia
Year: 2011

description: Economic regulation of business activities appears to be contrary to the philosophy of free enterprise. It can be justified only if it is imposed as a means to serve the public interest - to enhance the economic welfare of society - when the self interest of the producer is likely to prove harmful to the general interest of society. Public utilities are enterprises which have to be regulated in the interest of society and particularly the rates they may charge. In the regulation of utility rates, cost is often accepted as the proper basis for fixing the rates. Among the costs of rendering a utility service is the cost associated with the use of a capital asset, that is, depreciation expense. There are various bases on which depreciation expense is computed. Thus, there arises the problem of selecting a proper basis for determining the depreciation expense that is consistent with the purpose of rate regulation. An examination of current literature suggested that there is a case, on theoretical grounds, for adopting the current replacement cost approach to depreciation accounting when the purpose of fixing a utility rate is to serve the interest of society. The case appears strong when a marginal-cost standard is accepted for rate regulation since, under the assumption of continuity of operations, the cost of replacing the services of a capital asset is the long-run marginal (opportunity) cost of employing the asset in the enterprise; thus, a rate that is fixed on the basis of current replacement cost will promote optimum allocation of resources in the economy. Even if a "full-cost" standard is employed in the regulation of utility rates, there is still a case for determining depreciation expense on the basis of current replacement cost. A utility rate that is fixed on this basis is more comparable to the price charged in the non-utility sector of the economy and, thus, promotes better allocation of resources between the utility sector and the rest of the economy. It also provides the enterprise an opportunity to maintain intact its productive capacity if this is in the interest of society; for the ability of the enterprise to continue production in the future will not be impaired. It is recognized that there are practical problems associated with the application of the proposal to a real life situation. However, they are not insurmountable. They appear no greater than the problems associated with the use of reproduction cost new - a concept which has been applied in practice in the history of rate regulation.
Averaging in cosmological models using scalars

description: The averaging problem in cosmology is of considerable importance for the correct interpretation of cosmological data. A rigorous mathematical definition of averaging in a cosmological model is necessary. In general, a spacetime is completely characterized by its scalar curvature invariants, and this suggests a particular spacetime averaging scheme based entirely on scalars. We clearly identify the problems of averaging in a cosmological model. We then present a precise definition of a cosmological model, and based upon this definition, we propose an averaging scheme in terms of scalar curvature invariants. This scheme is illustrated in a simple static spherically symmetric perfect fluid cosmological spacetime, where the averaging scales are clearly identified.

Athermal All-Optical Femtosecond Magnetization Reversal in GdFeCo

description: Magnetization reversal in GdFeCo by circularly polarized light is shown to occur at the femtosecond time scale. In contrast to the well known laser-assisted magnetization reversal based on the laser heating, we here demonstrate that this femtosecond all-optical magnetization reversal is more efficient at lower temperatures. The lower the temperatures, the smaller the laser fluence required for the switching. This switching is in agreement with a more recent theoretical prediction $[ \text{Phys. Lett. A \textbf{372}, 1915 (2008)} ] $ and demonstrates the feasibility of the femtosecond athermal magnetization reversal.
Nonlinear quantum heat transfer in hybrid structures: Sufficient conditions for thermal rectification

description: We present a unified description of heat flow in two-terminal hybrid quantum systems. Using simple models, we analytically study nonlinear aspects of heat transfer between various reservoirs: metals, solids, and spin baths, mediated by the excitation/relaxation of a central (subsystem) mode. We demonstrate rich nonlinear current-temperature characteristics, originating from either the molecular anharmonicity, or the reservoirs (complex) energy spectra. In particular, we establish sufficient conditions for thermal rectification in two-terminal junctions. We identify two classes of rectifiers. In type-A rectifiers the density of states of the reservoirs are dissimilar. In type-B rectifiers the baths are identical, but include particles whose statistics differ from that of the subsystem, to which they asymmetrically couple. Nonlinear heat flow, and specifically thermal rectification, are thus ubiquitous effects that could be observed in a variety of systems, phononic, electronic, and photonic.
The assembly of fimbrial ushers, inverse autotransporters and LptDE into bacterial outer membranes
Creators: name: Stubenrauch, Christopher James
Publisher: name: Monash University
Year: 2016
Subjects: subject: Microbiology
subject: FOS: Biological sciences

description: The translocation and assembly module (TAM) is capable of assembling outer membrane proteins, but its function has remained enigmatic in that: (i) only the AIDA-like autotransporter family had been shown to require the TAM, and (ii) outer membrane protein biogenesis is generally considered to be catalysed only by the β-barrel assembly machinery (BAM) complex. To assess whether the TAM plays a broader role in β-barrel assembly, I developed a pulse chase assay to characterise the specific contributions of the TAM and the BAM complex for a range of outer membrane protein substrates.

 Working on the hypothesis that the TAM assembles more complicated outer membrane proteins that diverge from the classical β-barrel architecture, five candidate TAM substrates were analysed for their requirement of the TAM: FimD (a fimbrial usher), intimin (an inverse autotransporter), TolC, PhoE, and LptDE. While the PhoE data was inconclusive, the four remaining candidate substrates were found to have varying requirements for the TAM. Furthermore, six related fimbrial ushers and a second inverse autotransporter were also confirmed to require the TAM for efficient biogenesis.

 FimD contains an unusual extracellular loop that is readily proteolytically degraded on addition of exogenous proteinase K. Because distinct proteolytic fragmentation "fingerprints" were generated depending on the presence or absence of the TAM, this provided a tool to dissect the contribution of the TAM toward FimD biogenesis. The TAM was subsequently found to initiate β-barrel assembly from the C-terminal end of the substrate, and while the BAM complex was also capable of assembling FimD, it was significantly less efficient because it initiated β-barrel assembly from a central region of the protein. This data was interpreted to mean that the BAM complex is subsidiary to the TAM during fimbrial usher biogenesis.

 In contrast, although assembly of the LptDE complex was also shown to be assisted by the TAM, considering both the BAM and LptDE complexes are essential (but the TAM is not), the TAM likely plays a minor role in LptDE assembly that is subsidiary to the BAM complex. As such, the hypothesis that only the BAM complex is necessary for β-barrel biogenesis should be extended to include the contribution that TAM makes - depending on the substrate - as either the major or minor outer membrane protein insertase.

description: We continue the study of the so-called thematic factorizations of admissible very badly approximable matrix functions. These factorizations were introduced by V.V. Peller and N.J. Young for studying superoptimal approximation by bounded analytic matrix functions. Even though thematic indices associated with a thematic factorization of an admissible very badly approximable matrix function are not uniquely determined by the function itself, R.B. Alexeev and V.V. Peller showed that the thematic indices of any monotone non-increasing thematic factorization of an admissible very badly approximable matrix function are uniquely determined. In this paper, we prove the existence of monotone non-decreasing thematic factorizations for admissible very badly approximable matrix functions. It is also shown that the thematic indices appearing in a monotone non-decreasing thematic factorization are not uniquely determined by the matrix function itself. Furthermore, we show that the monotone non-increasing thematic factorization gives rise to a great number of other thematic factorizations.

description: The time resolved Magnetooptical Kerr effect in the substrate-strain-induced insulating ferromagnetic phase in (Pr$_{0.6}$Ca$_{0.4}$)MnO$_3$ thin films on two different substrates was measured in a magnetic field up to 1.1T. The photoinduced Kerr rotation and ellipticity show remarkably different magnetic-field dependence. From the comparison of the magnetic field dependencies of the photoinduced and static Kerr rotation and ellipticity we conclude that a transient ferromagnetic metallic phase, embedded within the insulating ferromagnetic phase, is created upon the photoexcitation at low temperatures. A comparison of temporal dependence of the photoinduced Kerr signals with the photoinduced reflectivity indicates the change of the fractions of the phases takes place on a timescale of ten picoseconds independent of the substrate.

Such scenario is supported by quantum simulations which consider different types of underlying disorders (smooth edge disorder and long range Coulomb scatters).

description: The floating-zone method with different growth ambiances has been used to selectively obtain hexagonal or orthorhombic DyMnO$_{3}$ single crystals. The crystals were characterized by X-ray powder diffraction of ground specimen and a structure refinement as well as electron diffraction. We report magnetic susceptibility, magnetisation, and specific heat studies of this multiferroic compound in both the hexagonal and the orthorhombic structure. The hexagonal DyMnO$_{3}$ shows magnetic ordering of Mn$^{3+}$ (S =2) spins on a triangular Mn lattice at $T^{\mathrm {Mn}}_{N}$ = 57 K characterized by a cusp in the specific heat. This transition is not apparent in the magnetic susceptibility due to the frustration on the Mn triangular lattice and the dominating paramagnetic susceptibility of the Dy$^{3+}$ (S=9/2) spins. At $T^{\mathrm {Dy}}_{N}$ = 3 K, a partial antiferromagnetic order of Dy moments has been observed. In comparison, the magnetic data for orthorhombic DyMnO$_{3}$ display three transitions. The data broadly agree with results from earlier neutron diffraction experiments, which allows for the following assignment: a transition from an incommensurate antiferromagnetic ordering of Mn$^{3+}$ spins at $T^{\mathrm {Mn}}_N$ = 39 K, a {\textit{lock--in}} transition at $T_{\mathrm {lock-in}}$ = 16 K and a second antiferromagnetic transition at $T^{\mathrm {Dy}}_N$ = 5 K due to the ordering of Dy moments. Both the hexagonal and the orthorhombic crystals show magnetic anisotropy and complex magnetic properties due to 4$f-4f$ and 4$f-3d$ couplings.

description: The recent observation by the PAMELA satellite of a rising positron fraction up to $\sim$ 100 GeV has triggered a considerable amount of putative interpretations in terms of dark matter (DM) annihilation or decay. Here, we make a critical reassessment of such a possibility, recalling the elementary conditions with respect to the standard astrophysical background that would make it likely, showing that they are not fulfilled. Likewise, we argue that, as now well accepted, DM would need somewhat contrived properties to contribute significantly to the observed positron signal, even when including e.g. clumpiness effects. This means that most of natural DM candidates arising in particle physics beyond the standard model are not expected to be observed in the cosmic antimatter spectrum, unfortunately. However, this does not prevent them from remaining excellent DM candidates, this only points towards the crucial need of developing much more complex detection strategies (multimessenger, multiwavelength, multiscale searches).

description: The total cross sections for the 120Te(p,gamma)121I and 120Te(p,n)120I reactions have been measured by the activation method in the effective center-of-mass energies between 2.47 MeV and 7.93 MeV. The targets were prepared by evaporation of 99.4 % isotopically enriched 120Te on Aluminum and Carbon backing foils, and bombarded with proton beams provided by the FN tandem accelerator at the University of Notre Dame. The cross sections and $S$ factors were deduced from the observed gamma ray activity, which was detected off-line by two Clover HPGe detectors mounted in close geometry. The results are presented and compared with the predictions of statistical model calculations using the codes NON-SMOKER and TALYS.

The Bougainville Referendum Arrangements: Origins,Shaping and ImplementationPart Two: Shaping and Implementation
Creators: name: Regan, Anthony
Publisher: name: Canberra, ACT: Dept. of Pacific Affairs, Research School of Pacific and Asian Studies, The Australian National University
Year: 2018

description: Having considered the origins and aspects of the shaping of the referendum arrangements in the first of these paired Discussion Papers, this paper presents an overview of the arrangements for the referendum as set out in the Bougainville Peace Agreement (BPA) and the constitutional laws that give effect to that agreement. This second Discussion Paper seeks to not only clarify some of the complexity of the arrangements, but also to address a few major misunderstandings that have arisen in recent public debates about the referendum arrangements. It also provides an overview of some of the developing activity towards the holding of the referendum. Further, it interrogates the mixed messages about the referendum emanating from Papua New Guinea (PNG) Prime Minister Peter O’Neill from late 2017.

Parton content of the nucleon from distribution amplitudes and transition distribution amplitudes

name: Pincetti, M.

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The nucleon distribution amplitudes and the nucleon-to-pion transition distribution amplitudes are investigated at leading twist within the frame of a light-cone quark model. The distribution amplitudes probe the three-quark component of the nucleon light-cone wave function, while higher order components in the Fock-space expansion of the nucleon state are essential to describe the nucleon-to-pion transition distribution amplitudes. Adopting a meson-cloud model of the nucleon the nucleon-to-pion transition distribution amplitudes are calculated for the first time.

Water adsorption and dissociation on SrTiO3(001) revisited: A density-functional theory study
Creators: name: Guhl, Hannes
name: Miller, Wolfram
name: Reuter, Karsten
Publisher: name: arXiv
Year: 2010
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: We present a comprehensive density-functional theory study addressing the adsorption, dissociation and successive diffusion of water molecules on the two regular terminations of SrTiO3(001). Combining the obtained supercell-geometry converged energetics within a first-principles thermodynamics framework we are able to reproduce the experimentally observed hydroxilation of the SrO-termination already at lowest background humidity, whereas the TiO2-termination stays free of water molecules in the regime of low water partial pressures. This different behavior is traced back to the effortless formation of energetically very favorable hydroxyl-pairs on the prior termination. Contrary to the prevalent understanding our calculations indicate that at low coverages also the less water-affine TiO2-termination can readily decompose water, with the often described molecular state only stabilized towards higher coverages.

Studies on the active region of botulinus toxins : involvement and sequence of a peptide in the region of the single cysteine residue in botulinus toxins types A, B and E
Creators: name: Van Alstyne, Diane
Publisher: name: University of British Columbia
Year: 2011

description: After establishing that, like types B and E toxins, type A botulinus toxin contains only one residue of cysteine per molecule, chemical modification studies were carried out showing that sulfhydryl-specific reagents like p-chloromercuribenzoate (PCMB) and N-(4-dimethyl-amino-3,5-dinitrophenyl) maleimide (DDPM) cause a marked decrease in toxicity. Types A, B and E toxins were reacted with DDPM and a labelled peptide was obtained from the tryptic digest of each of the toxins. The quantitative amino acid analyses of these three peptides were remarkably similar. Sequence analyses showed that a sequence ala-glu-ser-cys-ser-asp-ser is common to all three DDPS-peptides. Type B botulinus toxin does not enzymatically alter acetylcholine in order to cause flaccid paralysis. It is postulated that the three thiol-containing peptides isolated contain all or part of a postulated active site common to each of types A, B and E botulinus toxins.
Microscopic linear response calculations based on the Skyrme functional plus the pairing contribution
Creators: name: Li, Jun

Publisher: name: arXiv
Year: 2008
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: A self-consistent Quasiparticle-Random-Phase-Approximation (QRPA) model which employs the canonical Hartree-Fock-Bogoliubov (HFB) basis and an energy-density functional with a Skyrme mean field part and a density-dependent pairing, is used to study the monopole collective excitations of spherical even-even nuclei. The influence of the spurious state on the strength function of the isoscalar monopole excitations is clearly assessed. We compare the effect of different kinds of pairing forces (volume pairing, surface pairing and mixed pairing) on the monopole excitation strength function. The energy of the Isoscalar Giant Monopole Resonance (ISGMR), which is related to the nuclear incompressibility $K_{\infty}$, is calculated for tin isotopes and the results are discussed.

Existence and properties of travelling waves for the Gross-Pitaevskii equation
Creators: name: Béthuel, Fabrice

Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics
subject: 35Q40 (Primary), 35Q53, 35Q55, 35A05 (Secondary), 35B40

description: This paper presents recent results concerning the existence and qualitative properties of travelling wave solutions to the Gross-Pitaevskii equation posed on the whole space R^N. Unlike the defocusing nonlinear Schrödinger equations with null condition at infinity, the presence of non-zero conditions at infinity yields a rather rich and delicate dynamics. We focus on the case N = 2 and N = 3, and also briefly review some classical results on the one-dimensional case. The works we survey provide rigorous justifications to the impressive series of results which Jones, Putterman and Roberts established by formal and numerical arguments.

description: We consider 3d Schrodinger operator with long-range potential that has short-range radial derivative. The long-time asymptotics of non-stationary problem is studied and existence of modified wave operators is proved. It turns out, the standard WKB correction should be replaced by the solution to certain evolution equation.

description: We discuss the production of charmonium in nuclear collisions within the framework of the statistical hadronization model. We demonstrate that the model reproduces very well the availble data at RHIC. We provide predictions for the LHC energy where, dependently on the charm production cross section, a dramatically different behaviour of charmonium production as a function of centrality might be expected. We discuss also the case in elementary collisions, where clearly the statistical model does not reproduce the measurements.

Freedom from Reality: The Diabolical Character of Modern Liberty
Creators: name: Schindler, D.C.
Publisher: name: University of Notre Dame
Year: 2023

description: \u000aIt is commonly observed that behind many of the political and cultural issues that we face today there are impoverished conceptions of freedom, which, according to D. C. Schindler, we have inherited from the classical liberal tradition without a sufficient awareness of its implications. _Freedom from Reality_ presents a critique of the deceptive and ultimately self-subverting character of the modern notion of freedom, retrieving an alternative view through a new interpretation of the ancient tradition. While many have critiqued the inadequacy of identifying freedom with arbitrary choice, this book seeks to penetrate to the metaphysical roots of the modern conception by going back, through an etymological study, to the original sense of freedom.\u000a \u000aSchindler begins by uncovering a contradiction in John Locke's seminal account of human freedom. Rather than dismissing it as a mere 'academic' problem, Schindler takes this contradiction as a key to understanding the strange paradoxes that abound in the contemporary values and institutions founded on the modern notion of liberty: the very mechanisms that intend to protect modern freedom render it empty and ineffectual. In this respect, modern liberty is 'diabolical'-a word that means, at its roots, that which 'drives apart' and so subverts. This is contrasted with the 'symbolical' (a 'joining-together'), which, he suggests, most basically characterizes the premodern sense of reality. This book will appeal to students and scholars of political philosophy (especially political theorists), philosophers in the continental or historical traditions, and cultural critics with a philosophical bent.\u000a
Graphene with Structure-Induced Spin-Orbit Coupling: Spin-Polarized States, Spin Zero Modes, and Quantum Hall Effect

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: Spin splitting of the energy spectrum of single-layer graphene on Au/Ni(111) substrate has been recently reported. I show that eigenstates of spin-orbit coupled graphene are polarized in-plane and perpendicular to electron momentum $\bf k$; the magnitude of spin polarization $\bf S$ vanishes when $k \to 0$. In a perpendicular magnetic field $\bf B$, $\bf S$ is parallel to $\bf B$, and two zero modes emerge in the Landau level spectrum. Singular $\bf B$-dependence of their magnetization suggests existence of a novel magnetic instability. They also manifest themselves in a new unconventional quantum Hall effect.
