description: We explain the strong interlayer drag resistance observed at low temperatures in bilayer electron-hole systems in terms of an interplay between local electron-hole-pair condensation and disorder-induced carrier density variations. Smooth disorder drives the condensate into a granulated phase where interlayer coherence is formed only in well separated and disconnected regions, or grains, and the densities of electrons and holes accidentally match. The drag resistance is then dominated by Andreev scattering of charge carries between layers at the grains that transfers momentum between layers. We show that this scenario can account for the observed dependence of the drag resistivity on temperature, and on the average charge imbalance between layers.

Effect of the Uniform Random External Magnetic Field with Spatio-temporal Variation on Compensation in Ising Spin-1/2 Trilayered Square Ferrimagnet

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: Trilayered spin-1/2 Ising ferrimagnets are interesting thin systems for compensation phenomenon. In this work, a Metropolis Monte Carlo study is performed on the magnetic and thermodynamic response of such a system on square Bravais lattice, driven by uniform random external magnetic field with spatio-temporal variations. In two distinct configurations, the surface layers are made up of A and the mid-layer is made up of B atoms in a ABA type stacking while in AAB type stacking, the top-layer and the mid-layer is made up of A-atoms while the bottom layer is made up of B-atoms. The magnetic coupling between the like atoms (A-A and B-B) is ferromagnetic while between the unlike atoms (A-B), it is antiferromagnetic. For the time-dependent external uniform random field, the mean is always set to zero and the standard deviation is varied until spin-field energy is comparable to the dominant cooperative energy of the system. The findings show that the observed compensation and critical points shift and steady-state magnetic behaviours shift between N-, L-, P- and Q- etc. type of ferrimagnetic behaviours, depending upon the strength of external uniform random field. The compensation phenomenon even vanishes after crossing a finite threshold of standard deviation of the magnetic field for particular choices of the other controlling parameters. Thus islands of ferrimagnetic phase without compensation appear within the phase area with compensation of field-free case, in the 2D Hamiltonian parameter space. For both the configurations, the areas of such islands even grow with increasing standard deviation of the external field, σ, obeying a scaling relation of the form: $f (σ, A(σ)) = σ^{-b} A(σ)$ with $b_{ABA} = 1.958 \pm 0.122$ and $b_{AAB} = 1.783 \pm 0.118$ .

Bearing men : a cultural history of motherhood from the cycle plays to Shakespeare
Creators: name: Olchowy Rozeboom, Gloria
Publisher: name: University of British Columbia
Year: 2009

description: The scholars who assert that motherhood acquires new favor in the early modem period and the critics who contend that male subjectivity and patriarchy in Shakespeare's plays depend on the repudiation of the mother both base their perspectives on an understanding of motherhood which is too monolithic. To contribute to a more historically specific understanding, I draw on the work of numerous historians and examine humanist and reformist writings, the Corpus Christi cycles, and two Shakespearean plays. I find that the medieval "calculative" and "incarnational" versions of motherhood enabled women to exercise considerable control over their sexuality and fertility and clout in their families and communities, and that the Corpus Christi cycles served as a mechanism to extend multiple facets of these versions of the maternal. While the early modern period inherited the expansive, medieval versions of motherhood, the "new," restrictive form of motherhood advocated by the humanists and reformers helped to devalue the inherited forms, promote a greater spiritual, physical, and economic dependence of women on men, and enlarge the scope of the paternal at the expense of the maternal. My examination of Macbeth demonstrates that the play employs Scottish history so as to heighten attention to the risks produced by Elizabeth I's and James I's adaptations of the competing versions of motherhood available in the early modern period. It suggests that James's adaptation is especially conducive to instability, since it generates a contradiction in the hereditary system of political power-the simultaneous need for and exclusion of women/mothers. This contradiction coupled with the diminution of the feminine/maternal makes it more likely that murder will be construed as an alternative means of being "born" into the succession. Whereas Macbeth shifts from constructions more aligned with incarnational and calculative mothers to constructions more affiliated with new mothers, Coriolanus appears nearly throughout to be informed by the contest over motherhood. By exploring this contest, I add to the understanding of the economic, political, familial, and theatrical aspects of the play, and make it possible to suggest that Coriolanus demonstrates peace is achieved when a version of motherhood resembling the expansive, medieval forms is embraced.

description: Water quality and the need for pollution control in agriculture are well-established concerns in the United States. This paper addresses the effectiveness of using site-specific or spatial information to predict farm responses to a practice-standard NPS pollution control policy and the associated compliance costs. In this study a phosphorous-based nutrient management plan was used to evaluate four scenarios which make use of different amounts of information about farm characteristics. Results indicate more accurate predictions can be made using spatial information but there exists a need for further research.

description: Pairing correlations play a very important role in atomic nuclei. Although several effective pairing interactions have been used in mean field calculations for nucleons, little is known about effective pairing interactions for hyperons. Based on the quark model, we propose a relationship between effective pairing interactions for hyperons and for nucleons; e.g., for $Λ$s, the strength of the pairing interaction is 4/9 of that for nucleons. A separable pairing force of finite range which has been widely applied to describing pairing correlations in normal nuclei is used to investigate pairing effects in multi-$Λ$ Ca, Sn and Pb hypernuclei.

Swift observations of the prompt X-ray emission and afterglow from GRB050126 and GRB050219A

description: We report on the temporal and spectral characteristics of the early X-ray emission from the Gamma Ray Bursts GRB050126 and GRB050219A as observed by Swift. The X-ray light-curves of these 2 bursts both show remarkably steep early decays (F(t)\propto t^{-3}), breaking to flatter slopes on timescales of a few hundred seconds. For GRB050126 the burst shows no evidence of spectral evolution in the 20-150 keV band, and the spectral index of the gamma-ray and X-ray afterglows are significantly different suggesting a separate origin. By contrast the BAT spectrum of GRB050219A displays significant spectral evolution, becoming softer at later times, with Gamma evolving toward the XRT photon index seen in the early X-ray afterglow phase. For both bursts, the 0.2-10 keV spectral index pre- and post-break in the X-ray decay light-curve are consistent with no spectral evolution. We suggest that the steep early decline in the X-ray decay light-curve is either the curvature tail of the prompt emission; X-ray flaring activity; or external forward shock emission from a jet with high density regions of small angular size (> Gamma^{-1}). The late slope we associate with the forward external shock.

description: The paper investigates price dynamics under market liberalization, with a focus on the effects of lowering price floors. We analyze price dynamics by specifying and estimating a dynamic Tobit model under time-varying volatility, where the market price is censored by a government-set support price. The model is applied to the U.S. butter market over the last three decades. The econometric results show how the price support program affects both expected prices and the volatility of prices. It is found that the censoring effects of a price support program can be significant and large even if the price support is set relatively low.

We demonstrate that the ADD-model leads to strong correlations between the missing $E_T$ in gravitons at different center of mass energies. This correlation puts strong constraints on this model for extra dimensions, if probed at $\sqrt{s}=5.5$ TeV and $\sqrt{s}=14$ TeV at LHC.

description: An accreting system in two-temperature regime, admits multiple solutions for the same set of constants of motion, producing widely different spectra. Comparing observed spectrum with that derived from a randomly chosen accretion solution, will give us a wrong estimation of the accretion parameters of the system. The form of entropy measure obtained by us, have helped in removing the degeneracy of the solutions, allowing us to understand the physics of the system, shorn of arbitrary assumptions. In this work, we have shown how the spectra and luminosities of an accreting system depends on the constants of motion, producing solutions ranging from radiatively inefficient flows to luminous flows. Increase in BH mass quantitatively changes the system, makes the system more luminous and the spectral bandwidth also increases. Higher BH mass system spans from radio to gamma-rays. However, increasing the accretion rate around a BH of certain mass, has little influence in the frequency range of the spectra.

description: In this work we study an SO(10) GUT model with minimum Higgs representations belonging only to the 210 and 16 dimensional representations of SO(10). We add a singlet fermion S in addition to the usual 16 dimensional representation containing quarks and leptons. There are no Higgs bi-doublets and so charged fermion masses come from one-loop corrections. Consequently all the fermion masses, Dirac and Majorana, are of the see-saw type. We minimize the Higgs potential and show how the left-right symmetry is broken in our model where it is assumed that a D-parity odd Higgs field gets a vacuum expectation value at the grand unification scale. From the renormalization group equations we infer that in our model unification happens at 10^{15} GeV and left-right symmetry can be extended up to some values just above 10^{11} GeV. The Yukawa sector of our model is completely different from most of the standard grand unified theories and we explicitly show how the Yukawa sector will look like in the different phases and briefly comment on the running of the top quark mass. We end with a brief analysis of lepton number asymmetry generated from the interactions in our model.

description: There is no cure for brain glioblastoma yet even under the standard regimen of surgery to remove the tumour , with radiation and chemotherapy followed by alkylating agent temozolomide (TMZ).The CAR therapy has undergone various clinical trials and has revolutionized the field of cancer therapy.Until now, CAR techniques seem to cause less regression on solid tumours than hematological tumors partly due to difficulty in finding suitable tumor-specific antigens that can be targeted by CAR-T cells, without possible on-target/off-tumor toxicity leading to the unintentional damage of healthy cells that co-express the target antigen.This paper aims to review or discuss potential therapeutic advances against glioblastoma.Conclusion:Successful early screening in brain cancer is vital, in order to achieve a relative positive prognosis.Even after the elimination of all tumour cells in brain, tissue or nerve repair is exceedingly vital to the contribution of potential cure. Maintenance of all functions might not be achieved simultaneously when all tumour cells or cancer stem cells ought to be entirely eliminated to avoid proliferation of tumour cells.

description: Adapting variable rate technology (VRT) to Argentine conditions requires methods that use inexpensive information and that focus on the inputs and variability common to Argentine maize and soybean growing areas. The goal of this study is to determine if spatial regression analysis of yield monitor data can be used to estimate the site-specific crop Nitrogen (N) response needed to fine tune variable rate fertilizer strategies. N has been chosen as the focus of this study because it is the most commonly used fertilizer by corn farmers in Argentina. The methodology uses yield monitor data from on-farm trials to estimate site-specific crop response functions. The design involves a strip trial with a uniform N rate along the strip and a randomized complete block design, with regression estimation of N response curves by landscape position. Spatial autocorrelation and spatial heterogeneity are taken into account using a spatial error model and a groupwise heteroskedasticity model. A partial budget is used to calculate uniform rate and VRT returns. First year data indicate that N response differs significantly by landscape position, and that VRA for N may be modestly profitable on some locations depending on the VRT fee level, compared to a uniform rate of urea of 80kg ha-1. A more complete analysis will pool data over many farms and several years to determine if reliable differences exist in N response by landscape position or other type of management zone. The study is planned for four years. The purpose of this preliminary analysis is to show how spatial regression analysis of yield data could be used to fine tune input use.

description: We demonstrate that a large class of one-dimensional quantum and classical exchange models can be described by the same type of graphs, namely Cayley graphs of the permutation group. Their well-studied spectral properties allow us to derive crucial information about those models of fundamental importance in both classical and quantum physics, and to completely characterize their algebraic structure. Notably, we prove that the spectral gap can be obtained in polynomial computational time, which has strong implications in the context of adiabatic quantum computing with quantum spin-chains. This quantity also characterizes the rate to stationarity of some important classical random processes such as interchange and exclusion processes. Reciprocally, we use results derived from the celebrated Bethe ansatz to obtain original mathematical results about these graphs in the unweighted case. We also discuss extensions of this unifying framework to other systems, such as asymmetric exclusion processes -- a paradigmatic model in non-equilibrium physics, or the more exotic non-Hermitian quantum systems.

description: It has been shown that finding generic Bell states diagonal entanglement witnesses (BDEW) for $d_{1}\otimes d_{2}\otimes ....\otimes d_{n}$ systems exactly reduces to a linear programming if the feasible region be a polygon by itself and approximately obtains via linear programming if the feasible region is not a polygon. Since solving linear programming for generic case is difficult, the multi-qubits, $2\otimes N$ and $3 \otimes 3$ systems for the special case of generic BDEW for some particular choice of their parameters have been considered. In the rest of this paper we obtain the optimal non decomposable entanglement witness for $3 \otimes 3$ system for some particular choice of its parameters. By proving the optimality of the well known reduction map and combining it with the optimal and non-decomposable 3 $\otimes$ 3 BDEW (named critical entanglement witnesses) the family of optimal and non-decomposable 3 $\otimes$ 3 BDEW have also been obtained. Using the approximately critical entanglement witnesses, some 3 $\otimes$ 3 bound entangled states are so detected. So the well known Choi map as a particular case of the positive map in connection with this witness via Jamiolkowski isomorphism has been considered which approximately is obtained via linear programming.

description: We model the light curves of the novel and extremely luminous transient ASASSN-15lh at nine different frequencies, from infrared to ultra-violet photon energies, as an evolving relativistic disc produced in the aftermath of a tidal disruption event. Good fits to all nine light curves are simultaneously obtained when $M_{\rm acc} \simeq 0.07 M_{\odot}$ is accreted onto a black hole of mass $M \simeq 10^9 M_{\odot}$, and near maximal rotation $a/r_g = 0.99$. The best fit black hole mass is consistent with a number of existing estimates from galactic scaling relationships. If confirmed, our results represent the detection of one of the most massive rapidly spinning black holes to date, and are strong evidence for a TDE origin for ASASSN-15lh. This would be the first TDE to be observed in the disc dominated state at optical and infrared frequencies.

Thinking locally, acting globally : human security and the new solidarism in international society
Creators: name: Owens, Heather L.
Publisher: name: University of British Columbia
Year: 2009

description: Human security is a relatively new concept in the terminology of international relations, and yet it has become prominent relatively quickly in the pronouncements of both international organizations and a group of like-minded Northern states dedicated to human rights, humanitarian and human development agendas. Most significantly, the doctrine of human security was invoked during NATO's recent "humanitarian war" over Kosovo. Nevertheless, few have considered either the normative foundations of this new approach or the theoretical heritage of security more generally. After examining the contours of the human security approach, I will consider the "idea of security" in a historical and normative sense. It is possible to group approaches to the normative idea of security into three competing traditions in the political theory of international relations, based on the works of Hobbes, Kant and Grotius. Each of these thinkers will be studied and considered in the context of historical international association. It will be argued that at present, an international society in the Grotian sense prevails. This society can be described as an association of diverse states, based on the rule of law and interstate order rather than notions of universalist justice or cosmopolitan citizenship. This thesis will offer a critical examination of the concept and practice of human security as it has evolved to date, with particular emphasis placed on the Kantian/ cosmopolitan foundations of human security and how these conflict with the international rule of law. In particular, I will argue that where the provision of human security translates into forcible humanitarian intervention, the legal foundations of international society are undermined, and the certainty which the existing rules of international society created, diminished. In this way, human security presents considerable moral, practical, and prudential problems.

However, when nitrogen use is restricted, VRAT is used on all simulated fields.

It is shown that the covariant kappa-symmetry gauge fixation results in the action quadratic in the (super)twistor variables.

description: Measurements of nuclear spin-dependent parity-violating (NSD-PV) effects provide an excellent opportunity to test nuclear models and to search for physics beyond the Standard Model. Molecules possess closely-spaced states with opposite parity which may be easily tuned to degeneracy to greatly enhance the observed parity-violating effects. A high-sensitivity measurement of NSD-PV effects using light triatomic molecules is in preparation [E. B. Norrgard, et al., Commun. Phys. 2, 77 (2019)]. Importantly, by comparing these measurements in light nuclei with prior and ongoing measurements in heavier systems, the contribution to NSD-PV from $Z^0$-boson exchange between the electrons and the nuclei may be separated from the contribution of the nuclear anapole moment. Furthermore, light triatomic molecules offer the possibility to search for new particles, such as the postulated $Z^{\prime}$ boson. In this work, we detail a sensitive measurement scheme and present high-accuracy molecular and nuclear calculations needed for interpretation of NSD-PV experiments on triatomic molecules composed of light elements Be, Mg, N, and C. The ab initio nuclear structure calculations, performed within the No-Core Shell Model (NCSM) provide a reliable prediction of the magnitude of different contributions to the NSD-PV effects in the four nuclei. These results differ significantly from the predictions of the standard single-particle model and highlight the importance of including many-body effects in such calculations. In order to extract the NSD-PV contributions from measurements, a parity-violating interaction parameter $W_{\text{PV}}$, which depends on molecular structure, needs to be known with high accuracy. We have calculated these parameters for the triatomic molecules of interest using the relativistic coupled-cluster approach.

Resonant CP Violation in Higgs Radiation at e^+e^- Linear Collider

description: We study resonant CP violation in the Higgsstrahlung process e^+e^- -> H_{1,2,3} (Z -> e^+e^-, μ^+μ^-) and subsequent decays H_{1,2,3} -> b \bar{b}, τ^-τ^+, in the MSSM with Higgs-sector CP violation induced by radiative corrections. At a high-energy e^+e^- linear collider, the recoil-mass method enables one to determine the invariant mass of a fermion pair produced by Higgs decays with a precision as good as 1 GeV. Assuming an integrated luminosity of 100/fb, we show that the production lineshape of a coupled system of neutral Higgs bosons decaying into b\bar{b} quarks is sensitive to the CP-violating parameters. When the Higgs bosons decay into τ^-τ^+, two CP asymmetries can be defined using the longitudinal and transverse polarizations of the tau leptons. Taking into account the constraints from electric dipole moments, we find that these CP asymmetries can be as large as 80 %, in a tri-mixing scenario where all three neutral Higgs states of the MSSM are nearly degenerate and mix significantly.

description: The stationary, spherically symmetric accretion of dark energy onto a Schwarzschild black hole is considered in terms of relativistic hydrodynamics. The approximation of an ideal fluid is used to model the dark energy. General expressions are derived for the accretion rate of an ideal fluid with an arbitrary equation of state p=p(ρ) onto a black hole. The black hole mass was found to decrease for the accretion of phantom energy. The accretion process is studied in detail for two dark energy models that admit an analytical solution: a model with a linear equation of state, p=α(ρ-ρ_0), and a Chaplygin gas. For one of the special cases of a linear equation of state, an analytical expression is derived for the accretion rate of dark energy onto a moving and rotating black hole. The masses of all black holes are shown to approach zero in cosmological models with phantom energy in which the Big Rip scenario is realized.

description: We have demonstrated strong antiferromagnetic coupling between two three-junction flux qubits based on a shared Josephson junction, and therefore not limited by the small inductances of the qubit loops. The coupling sign and magnitude were measured by coupling the system to a high-quality superconducting tank circuit. Design modifications allowing to continuously tune the coupling strength and/or make the coupling ferromagnetic are discussed.

description: To make certain quantitative interpretations of spectra from NMR experiments carried out on heterogeneous samples, such as cells and tissues, we must be able to estimate the magnetic and electric fields experienced by the resonant nuclei of atoms in the sample. Here, we analyze the relationships between these fields and the fields obtained by solving the Maxwell equations that describe the bulk properties of the materials present. This analysis separates the contribution to these fields of the molecule in which the atom in question is bonded, the "host" fields, from the contribution of all the other molecules in the system, the "external" fields. We discuss the circumstances under which the latter can be found by determining the macroscopic fields in the sample and then removing the averaged contribution of the host molecule. We demonstrate that the results produced by the, so-called, "sphere of Lorentz" construction are of general validity in both static and time-varying cases. This analytic construct, however, is not "mystical" and its justification rests not on any sphericity in the system but on the local uniformity and isotropy, i.e., spherical symmetry, of the medium when averaged over random microscopic configurations. This local averaging is precisely that which defines the equations that describe the macroscopic fields. Hence, the external microscopic fields, in a suitably averaged sense, can be estimated from the macroscopic fields. We then discuss the calculation of the external fields and that of the resonant nucleus in NMR experiments.

description: The role of international trade in the new growth theory is investigated from several perspectives. Following a historical outline and a brief analytical sketch of the R&D based models, the results from fitting three structural models to data are presented. Results show the relative impacts on growth from trade and R&D based policies including technological spillovers from trade. The mechanism of inter-sectoral adjustments to the long-run growth path are also discussed. Results from selected econometric studies are reviewed. With emphasis on agriculture, this includes evidence of technological spillovers from trade, the effect of R&D expenditures on growth in total factor productivity, and the extent to which the stock of technological knowledge is accessible by others.

Connecting 3D evolution of Coronal Mass Ejections to their Source Regions

description: Since Coronal Mass Ejections (CMEs) are the major drivers of space weather, it is crucial to study their evolution starting from the inner corona. In this work we use Graduated Cylindrical Shell (GCS) model to study the 3D evolution of 59 CMEs in the inner ($$ 3R$_{\odot}$) corona using observations from COR-1 and COR-2 on-board Solar TErrestrial RElations Observatory (STEREO) spacecraft. We identify the source regions of these CMEs and classify them as CMEs associated with Active Regions (ARs), Active Prominences (APs), and Prominence Eruptions (PEs). We find 27 $\%$ of CMEs show true expansion and 31 $\%$ show true deflections as they propagate outwards. Using 3D kinematic profiles of CMEs, we connect the evolution of true acceleration with the evolution of true width in the inner and outer corona. Thereby providing the observational evidence for the influence of the Lorentz force on the kinematics to lie in the height range of $2.5-3$ R$_{\odot}$. We find a broad range in the distribution of peak 3D speeds and accelerations ranging from 396 to 2465 km~s$^{-1}$ and 176 to 10922 m~s$^{-2}$ respectively with a long tail towards high values coming mainly from CMEs originating from ARs or APs. Further, we find the magnitude of true acceleration is be inversely correlated to its duration with a power law index of -1.19. We believe that these results will provide important inputs for the planning of upcoming space missions which will observe the inner corona and the models that study CME initiation and propagation.
