The Stability of Magnetized Rotating Plasmas with Superthermal Fields

Year: 2004

description: During the last decade it has become evident that the magnetorotational instability is at the heart of the enhanced angular momentum transport in weakly magnetized accretion disks around neutron stars and black holes. In this paper, we investigate the local linear stability of differentially rotating, magnetized flows and the evolution of the magnetorotational instability beyond the weak-field limit. We show that, when superthermal toroidal fields are considered, the effects of both compressibility and magnetic tension forces, which are related to the curvature of toroidal field lines, should be taken fully into account. We demonstrate that the presence of a strong toroidal component in the magnetic field plays a non-trivial role. When strong fields are considered, the strength of the toroidal magnetic field not only modifies the growth rates of the unstable modes but also determines which modes are subject to instabilities. We find that, for rotating configurations with Keplerian laws, the magnetorotational instability is stabilized at low wavenumbers for toroidal Alfven speeds exceeding the geometric mean of the sound speed and the rotational speed. We discuss the significance of our findings for the stability of cold, magnetically dominated, rotating fluids and argue that, for these systems, the curvature of toroidal field lines cannot be neglected even when short wavelength perturbations are considered. We also comment on the implications of our results for the validity of shearing box simulations in which superthermal toroidal fields are generated.

Identification of mutagens in drinking water and classification of mutations on DNA
Creators: name: Lu, Chuang
Publisher: name: American University
Year: 2023

description: The objective of this work was to develop a method to recover and identify mutagenic electrophiles present in drinking water and then to develop a method for rapidly determining the types of mutation such mutagens create in DNA. I. 5,5$\sp\prime$-dithiobis-(2-nitrobenzoic acid) was esterified to a carbohydrate polymer coating on controlled pore glass and reduced to the free thiol, creating an immobilized nucleophile, 5-mercapto-2-nitrobenzoyl (MNB) glass. MNB glass was used to trap the electrophilic mutagens present in drinking water concentrates (DWC). After washing to remove non-covalently bound material, the nucleophile-electrophile adducts were released by treatment with strong base. HPLC was used to separate and purify these products. II. A series of polycyclic aromatic hydrocarbon diol epoxides (PAHDEs) and small alkylating agents was tested for mutagenicity in Salmonella typhimurium strains TA100 and TA104. The relative levels of mutagenicity observed in the two strains correlated with the known amounts of adduct formed at dG and dA by the compounds, suggesting that the relative response of the two strains might be used to predict unknown ratios of chemical attack of a mutagen on dG vs dA in DNA. The analysis with TA100 and TA104 was then extended to DWC and the DWC mutagen MX, whose extent of reaction with dG vs dA is unknown. The results indicated MX is a dG favoring mutagen while the mutagens in DWC other than MX are more dA favoring compared to MX. The F$\sp\prime$ episomes of six LacZ$\sp-$ Escherichia coli (E. coli) strains, CC101-106, each of which is reverted by one of the six possible base pair substitutions, were transferred to E. coli strain EE122, which carries $\Delta$uvrB and rfa, to create six intermediate strains, CL101-106. Plasmid pKM101 was transferred to CL101-106 to create six new strains, CL101P-106P. The CL101P-106P strains were treated in parallel with a set of PAHDEs to generate mutational spectra or quantitative measurements of the relative amounts of the six kinds of point mutation that are produced by the compounds. The results were close to the published mutational spectra for these compounds, which were determined by various DNA sequencing studies, except CL103P (reverted by GC $\to$ CG transversions) responded very poorly. Excluding the underresponsiveness of CL103P, PAHDEs mainly created GC $\to$ TA and AT $\to$ TA transversions (70-80%) while MX mostly generated GC $\to$ TA and AT $\to$ CG transversions (90%).
Statistical physics near the critical point: An analysis of some free energy function models
Creators: name: Croce, John Philip
Publisher: name: American University
Year: 2023

description: This dissertation describes the fundamental statistical thermodynamics of a simple fluid near the critical point. Various free energy function models are analyzed. A theory of particulate interactive effects developed by Professor John A. White of The American University, and based on renormalization group concepts, is applied using numerical methods. Results for pressure-density isotherms, density-temperature coexistence curves, and specific heat near the critical point are presented. The paper is divided into six sections: (1) Introduction. Fundamental thermodynamics is presented in terms of the free energy function. (2) Basic theory. A model of intermolecular interactions is described which accounts for short range attractive forces using increasingly long correlation lengths based on renormalization group methods. (3) Specific heat. The theory of the specific heat near the critical point is developed for the liquid-gas two-phase region. (4) The iterative algorithm. A computer model in FORTRAN has been developed which numerically calculates thermodynamic parameters. (5) Numerical results. The numerical output of the iterative algorithms is compared to experimental data for: pressure-density isotherms, density-temperature coexistence curves, and specific heat. (6) Summary and conclusions. An assessment of the relationship of the theory to experimental data is made.
A Conical Tear Drop as a Vacuum-Energy Drain for the Solution of the Cosmological Constant Problem
Creators: name: Kehagias, Alex
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We propose a partial solution to the cosmological constant problem by using the simple observation that a three-brane in a six-dimensional bulk is flat. A model is presented in which Standard Model vacuum energy is always absorbed by the transverse space. The latter is a tear-drop like space with a conical singularity, which preserves bulk supersymmetry and gives rise to conventional macroscopic 4D gravity with no cosmological constant. Its cone acts like a drain, depleting vacuum energy from the three-brane to the tear drop increasing its volume. We stress that although gravity is treated classically, Standard Model is handled quantum-field theoretically and the model is robust against Standard Model corrections and particular details. The price paid is the presence of boundaries which are nevertheless physically harmless by appropriate boundary conditions.

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: We present observations of the massive transitional star W243 in Westerlund 1. We find an apparent spectral type of early-mid A from our data, in contrast to an earlier classification of B2I, made from data obtained in 1981. The concurrent development of a rich emission line spectrum suggests a very high mass loss rate; the continued presence of HeI emission suggesting that the underlying star remains significantly hotter than implied by its apparent spectral type. We suggest that W243 is a Luminous Blue Variable undergoing an eruptive phase, leading to an extreme mass loss rate and the formation of a pseudo photosphere.

We observed a second epoch for the TIC-231005575 system (Tmag = 12.06, Teff = 5500 +- 85 K) with NGTS and a third epoch with Las Cumbres Observatory's (LCO) telescope in South Africa to constrain the orbital period (P = 61.777 d). Subsequent radial velocity measurements with CORALIE revealed the transiting object has a mass of M2 = 0.128 +- 0.003 M$_\odot$, indicating the system is a G-M binary. The radius of the secondary is R2 = 0.154 +- 0.008 R$_\odot$ and is consistent with models of stellar evolution to better than 1-$σ$.

description: We study the structure of the vortex core in two-component Bose-Einstein condensates. We demonstrate that the order parameter may not vanish and the symmetry may not be restored in the core of the vortex. In this case such vortices can form vortex rings known as vortons in particle physics literature. In contrast with well-studied superfluid $^4He$, where similar vortex rings can be stable due to Magnus force only if they move, the vortex rings in two-component BECs can be stable even if they are at rest. This beautiful effect was first discussed by Witten in the cosmic string context, where it was shown that the stabilization occurs due to condensation of the second component of the field in the vortex core. This second condensate trapped in the core may carry a current along the vortex ring counteracting the effect of string tension that causes the loop to shrink. We speculate that such vortons may have been already observed in the laboratory. We also speculate that the experimental study of topological structures in BECs can provide a unique opportunity to study cosmology and astrophysics by doing laboratory experiments.

A comparative study of the attitudes toward international students as a function of selected characteristics of deaf college preparatory students

description: The purpose of this study was to determine differences, if any, in attitudes toward international students, as assessed through the Social Distance Scale (SDS), between samples of male and female deaf college preparatory students, who have deaf or hearing parents, and a mainstream versus residential or day-school-for-the-deaf precollege educational experience. Three hypotheses guided the study: (1) The mean SDS score for deaf preparatory college students who attended mainstreamed schools prior to attending Gallaudet University will be significantly lower than that for deaf preparatory students who attended residential or day schools for the deaf prior to attending Gallaudet University. (2) The mean SDS score for deaf preparatory college students with hearing parents will be significantly lower than that for deaf preparatory college students with deaf parents. (3) The mean SDS score for female deaf preparatory college students will be significantly lower than that for male deaf preparatory college students. The population of this study consisted of 163 volunteer deaf college preparatory students at the School of Preparatory Studies, Gallaudet University, in the fall semester of the 1992 academic year. These students were recruited during their group meetings at New Student Orientation. Of the 163 students, 110 attended residential or day schools for the deaf and 53 attended mainstreamed programs prior to coming to Gallaudet. Eighteen students had deaf parents and 145 had hearing parents. Eighty-four were females and 79 were males. The three hypotheses were not confirmed. Gender was the only variable that came very close to the.05 level of significance ($p = .059$), and on this variable, females showed lower social distance scores than males. In general, it is concluded that the effects of same minority group membership (as defined by deafness), regardless of school background, parental hearing status, or gender, leads to similar experiences and perceptions of other cultural out-groups.

description: Tunneling and Coulomb drag are sensitive probes of spontaneous interlayer phase coherence in bilayer two-dimensional electron systems at total Landau level filling factor $ν_T = 1$. We find that the phase boundary between the interlayer phase coherent state and the weakly-coupled compressible phase moves to larger layer separations as the electron density distribution in the bilayer is imbalanced. The critical layer separation increases quadratically with layer density difference.

description: We investigate the properties of the host galaxies of compact binary mergers across cosmic time. To this end, we combine population synthesis simulations together with galaxy catalogues from the hydrodynamical cosmological simulation EAGLE to derive the properties of the host galaxies of binary neutron star (BNS), black hole-neutron star (BHNS) and binary black hole (BBH) mergers. Within this framework, we derive the host galaxy probability, i.e., the probability that a galaxy hosts a compact binary coalescence as a function of its stellar mass, star formation rate, $K_s$ magnitude and $B$ magnitude. This quantity is particularly important for low-latency searches of gravitational wave (GW) sources as it provides a way to rank galaxies lying inside the credible region in the sky of a given GW detection, hence reducing the number of viable host candidates. Furthermore, even if no electromagnetic counterpart is detected, the proposed ranking criterion can still be used to classify the galaxies contained in the error box. Our results show that massive galaxies (or equivalently galaxies with a high luminosity in $K_s$ band) have a higher probability of hosting BNS, BHNS, and BBH mergers. We provide the probabilities in a suitable format to be implemented in future low-latency searches.

description: Optimal state transport across spin chains, which are proposed as quantum wires for information transfer in solid state quantum architectures, is an important topic for quantum technologies. In this work, we study {the remote restoring of a quantum state transferred along a spin chain.} The structural state-restoring technique provides proportionality between the appropriate elements of the density matrices of the initial sender state and receiver state at some time instant. We develop a {remote} state-restoring protocol which uses an inhomogeneous magnetic field with step-wise time-dependent Larmor frequencies as the state-control tool. For simulating the multiparametric Hamiltonian we use two approximating models. First model is based on the Trotter-Suzuki method, while the second model is based on using short pulses of high intensity. In both cases we estimate the accuracy of the approximation and find the optimal restoring parameters (Larmor frequencies) of the protocol which maximize the coefficients in the proportionality for spin chains of various lengths.

description: The interplay of nuclear and Coulomb processes in the inelastic excitation of single- and double-phonon giant resonances in heavy ion collisions is studied within a simple reaction model. Predominance of the Coulomb excitation mechanism on the population of the single-phonon and, on the contrary, predominance of the nuclear excitation for the double-phonon is evidenced. The effect of the spreading of the strength distribution of the giant resonances on the excitation process is analyzed, showing sizeable modifications in the case of Coulomb dominated processes.

description: We obtain the electronic states and structures of two-dimensional cobalt oxides, Na$_{x}$CoO$_{2}$ (x=0, 0.35, 0.5 and 0.75) by utilizing the full-potential linear muffin-tin orbitals (FP-LMTO) methods, from which some essential electronic interaction parameters are estimated: the bare on-site Coulomb interaction of cobalt U$_{dd}$=7.5 eV renormalizes to 5 eV for x=0.35, the $pd$ hybridizations t$_{pdσ}$ and t$_{pdπ}$ are -1.40 and 0.70 eV, respectively. The density of states at E$_{F}$ decreases from 6-7 states/eV in the local density approximation (LDA) to about 1.0 states/eV in the LDA+U scheme. The role of the intercalation of water molecules and the microscopic mechanism of the superconductivity in Na$_{0.35}$CoO$_{2}$$\cdot$mH$_{2}$O is discussed.

A comparative study of the attitudes toward international students as a function of selected characteristics of deaf college preparatory students
Creators: name: Lewis, Nancy Jones
Publisher: name: American University
Year: 2023

description: The purpose of this study was to determine differences, if any, in attitudes toward international students, as assessed through the Social Distance Scale (SDS), between samples of male and female deaf college preparatory students, who have deaf or hearing parents, and a mainstream versus residential or day-school-for-the-deaf precollege educational experience. Three hypotheses guided the study: (1) The mean SDS score for deaf preparatory college students who attended mainstreamed schools prior to attending Gallaudet University will be significantly lower than that for deaf preparatory students who attended residential or day schools for the deaf prior to attending Gallaudet University. (2) The mean SDS score for deaf preparatory college students with hearing parents will be significantly lower than that for deaf preparatory college students with deaf parents. (3) The mean SDS score for female deaf preparatory college students will be significantly lower than that for male deaf preparatory college students. The population of this study consisted of 163 volunteer deaf college preparatory students at the School of Preparatory Studies, Gallaudet University, in the fall semester of the 1992 academic year. These students were recruited during their group meetings at New Student Orientation. Of the 163 students, 110 attended residential or day schools for the deaf and 53 attended mainstreamed programs prior to coming to Gallaudet. Eighteen students had deaf parents and 145 had hearing parents. Eighty-four were females and 79 were males. The three hypotheses were not confirmed. Gender was the only variable that came very close to the.05 level of significance ($p = .059$), and on this variable, females showed lower social distance scores than males. In general, it is concluded that the effects of same minority group membership (as defined by deafness), regardless of school background, parental hearing status, or gender, leads to similar experiences and perceptions of other cultural out-groups.

description: Spin-gapless semiconductors (SGSs) are a promising class of materials for spintronic applications, enabling functions beyond conventional electronics. This study introduces a novel design for multifunctional spintronic field-effect transistors (FETs) using SGSs and/or spin-gapped metals (SGMs) as source and drain electrodes. These devices operate similarly to metal-semiconductor Schottky barrier FETs, where a potential barrier forms between the SGS (or SGM) electrode and the semiconducting channel. Unlike traditional Schottky barrier FETs, these devices utilize the unique spin-dependent transport properties of SGS/SGM electrodes to achieve sub-60 mV/dec switching, overcoming the 60 mV/dec sub-threshold swing limit in MOSFETs for low-voltage operation. Additionally, SGMs contribute a negative differential resistance (NDR) effect with an ultra-high peak-to-valley current ratio. The proposed spintronic FETs combine sub-60 mV/dec switching, non-local giant magnetoresistance (GMR), and NDR, making them suitable for applications like logic-in-memory computing and multivalued logic. These properties support computing architectures beyond the von-Neumann model, enabling efficient data processing. Two-dimensional (2D) nanomaterials provide a promising platform for these multifunctional FETs. We screen a computational 2D materials database to identify suitable SGS and SGM materials, selecting VS$2$ as the SGS for simulations. Using a non-equilibrium Green's function method with density functional theory, we simulate transfer ($I{\mathrm{D}}$-$V_{\mathrm{G}}$) and output ($I_{\mathrm{D}}$-$V_{\mathrm{D}}$) characteristics of a VS$_2$/Ga$_2$O$_2$ FET based on 2D type-II SGS VS$_2$, predicting a sub-threshold swing of 20 mV/dec, a high on/off ratio of 10$^8$, and a notable non-local GMR effect, demonstrating potential for low-power, high-performance applications.

The $πη$ interaction and $a_0$ resonances in photon-photon scattering

description: We revisit the information on the two lightest $a_0$ resonances and $S$-wave $πη$ scattering that can be extracted from photon-photon scattering experiments. For this purpose we construct a model for the $S$-wave photon-photon amplitudes which satisfies analyticity properties, two-channel unitarity and obeys the soft photon as well as the soft pion constraints. The underlying I=1 hadronic $T$-matrix involves six phenomenological parameters and is able to account for two resonances below 1.5 GeV.We perform a combined fit of the $γγ\to πη$ and $γγ\to K_SK_S$ high statistics experimental data from the Belle collaboration. Minimisation of the $χ^2$ is found to have two distinct solutions with approximately equal $χ^2$. One of these exhibits a light and narrow excited $a_0$ resonance analogous to the one found in the Belle analysis. This however requires a peculiar coincidence between the $J=0$ and $J=2$ resonance effects which is likely to be unphysical. In both solutions the $a_0(980)$ resonance appears as a pole on the second Riemann sheet. The location of this pole in the physical solution is determined to be $m-iΓ/2=1000.7^{+12.9}_{-0.7} -i\,36.6^{+12.7}_{-2.6}$ MeV. The solutions are also compared to experimental data in the kinematical region of the decay $η\toπ^0γγ$. In this region an isospin violating contribution associated with $π^+π^-$ rescattering must be added for which we provide a dispersive evaluation.

description: Ultrasound velocity measurements of the unconventional superconductor CeCoIn_5 with extremely large Pauli paramagnetic susceptibility reveal an unusual structural transformation of the flux line lattice (FLL) in the vicinity of the upper critical field. The transition field coincides with that at which heat capacity measurements reveal a second order phase transition. The lowering of the sound velocity at the transition is consistent with the collapse of the FLL tilt modulus and a crossover to quasi two-dimensional FLL pinning. These results provide a strong evidence that the high field state is the Fulde-Ferrel-Larkin-Ovchinikov phase, in which the order parameter is spatially modulated and has planar nodes aligned perpendicular to the vortices.

Quark Dipole Operators in Extended Technicolor Models

description: We study diagonal and transition quark dipole operators in a class of extended technicolor (ETC) models, taking account of the multiscale nature of the ETC gauge symmetry breaking and of the mixing among ETC interaction eigenstates. Because of this mixing, terms involving the lowest ETC scale can play an important role in dipole operators, and we focus on these terms. We derive from experiment new correlated constraints on the quark mixing angles and phases. Our bounds yield information on mixing angles individually in the up- and down-sectors, for both left- and right-handed quark fields and thus constrain even quark mixing parameters that do not enter in the CKM matrix. With phases of order unity, we conclude that these mixing angles are small, constraining future ETC model building, but plausibly in the range suggested by the size of the CKM elements. These values still allow substantial deviations from the standard model predictions, in particular for several CP violating quantities, including the asymmetries in $b \to s γ$ and $B_{d} \to ϕK_S$, $Re(ε^\prime/ε)$, and the electric dipole moments of the neutron and the ${}^{199}$Hg atom.

description: In many practical problems, one common question is to find a measure of vector associations. An example is marine surface wind data. Wind data are collected from buoys located in a certain areas on the sea surface. A typical observation of wind data is composed of two components, wind speed and wind direction. For two buoys or two groups of buoys, two sets of observations can be obtained. A measure of association of the two sets of observations will provide an additional tool for understanding the sea surface wind. Theoretical problems are raised in defining such a measure of association and in investigating its statistical properties. While the definition of a vector correlation coefficient is not unique, one definition has been proposed by Jupp & Mardia (1980). The sample distributional properties of such a vector correlation coefficient $r\sp2$ have been studied by many authors. This is because the statistic is a function of the canonical correlation coefficients. The exact distribution of the sample statistic $r\sp2$ under the alternative hypothesis of independence has not been well established. However, detailed asymptotic distributional properties are derived for both normal and nonnormal marginal distributions. The limiting distribution of ${nr}\sp2$ is shown to be a linear combination of noncentral chi-square variate with one degree of freedom and the noncentrality parameters determined by a function of the Pearson correlation coefficients of each pair of components of vectors, with weights being related to the fourth order moments of the marginal distributions. By appropriately selecting the weights in such a linear combination, the limiting distribution of ${nr}\sp2$ is expressed as a sum of a series of noncentral chi-square distributions. By utilizing additional independent observations from the marginal distributions, the power of the test of the independence of two vectors is higher. Simulation studies are applied to verify the theoretical results. The simulation results showed that the limiting distribution provides good fit for large sample sizes under normal marginal distributions. For dependent vectors with nonnormal marginal distributions, the results did not show uniformly a satisfactory fit. Possible reasons are truncating errors in computing the infinite series, and estimating procedures of the fourth order moments. Further studies are proposed to carry out. An application to the marine surface wind data is carried out using bootstrap techniques.
