description: Substrates have strong effects on optoelectronic properties of two-dimensional (2D) materials, which have emerged as promising platforms for exotic physical phenomena and outstanding applications. To reliably interpret experimental results and predict such effects at 2D interfaces, theoretical methods accurately describing electron correlation and electron-hole interaction such as first-principles many-body perturbation theory are necessary. In our previous work [Phys. Rev. B 102, 205113(2020)], we developed the reciprocal-space linear interpolation method that can take into account the effects of substrate screening for arbitrarily lattice-mismatched interfaces at the GW level of approximation. In this work, we apply this method to examine the substrate effect on excitonic excitation and recombination of 2D materials by solving the Bethe-Salpeter equation. We predict the nonrigid shift of 1s and 2s excitonic peaks due to substrate screening, in excellent agreements with experiments. We then reveal its underlying physical mechanism through 2D hydrogen model and the linear relation between quasiparticle gaps and exciton binding energies when varying the substrate screening. At the end, we calculate the exciton radiative lifetime of monolayer hexagonal boron nitride with various substrates at zero and room temperature, as well as the one of WS2 where we obtain good agreement with experimental lifetime. Our work answers important questions of substrate effects on excitonic properties of 2D interfaces.

Songs and Verses of New Ethnicities: Resistenza e rappresentazione nella cultura black British
Creators: name: Cattani, Francesco
Publisher: name: Università degli Studi di Cagliari
Year: 2015
Subjects: black Britain; Handsworth Songs; John Akomfrah; Salman Rushdie; Stuart Hall; rappresentazione

description: Il saggio prende avvio da un analisi del ‘documentario’ Handsworth Songs, girato dai Black Audio Film Collective nel 1986 e ispirato agli scontri che hanno infiammato la città di Birmingham nel 1985. Mescolando Storia, storie e materiale d’archivio, esso cerca di dare una nuova prospettiva su quello che i media avevano fatto passare come ‘looting’, senza indagarne (spesso negandone) le ragioni sociali e politiche. Presentandosi come riflessione sul presente delle lotte delle comunità black in Gran Bretagna e contemporaneamente come ricerca stilistica ed estetica, Handsworth Songs diventa una tappa fondamentale nella nascita di una tradizione critica black British.

La sua proiezione genera, infatti, una serie di reazioni opposte e controverse, in particolare la pubblicazione sul Guardian dei commenti di Salman Rushdie e Stuart Hall. Nella polemica che ne scaturisce si esplica il tentativo di individuare un diverso modo per rappresentare tanto i riot, come forma di resistenza e affermazione, quanto il black British, come soggetto politico British e non più ‘altro’, estraneo ai confini geografici e culturali nazionali.

Le posizioni opposte di Rushdie e Hall costituiscono un tentativo di rimettere in discussione i discorsi e i regimi di rappresentazione ‘ufficiali’, al fine di individuare nuove pratiche di rappresentazione autonome e lontane da marginalizzazioni o ‘mitiche criminalizzazioni’ (Paul Gilroy).
Proprio dopo questa polemica, non a caso, saranno pubblicati due testi centrali alla storia culturale della black Britain: “New Ethnicities” (1988) di Stuart Hall e The Satanic Verses (1988) di Salman Rushdie, in cui sembrano confluire in parte le riflessioni generate dalla visione di Handsworth Songs, che porteranno a una fondamentale ri-definizione e re-visione della blackness.

I remind until I fall: an examination of space, memory and experience at the Coqualeetza Residential School and Indian hospital
Creators: name: Woods, Jody
Publisher: name: University of British Columbia
Year: 2009

description: Through a theoretical and practical examination of how space is socially constructed and perceived, this study hypothesizes that the monolithically negative portrayal in the media and academic literature of the Indian residential school experience does not adequately reflect the full range of the experiences of all children at such institutions. A typology of spaces is constructed which establishes that concepts of gender, race and age impact the ways that institutions and institutional spaces are organized and perceived. This typology is applied to the Coqualeetza Residential School and the Coqualeetza Indian Tuberculosis Hospital in Sardis, BC for the period 1935 - 1950. Interviews were conducted with former Coqualeetza residents. Their comments, along with extant accounts of residential school experiences were examined within the context of this typology. The results reveal that, at Coqualeezta and at other residential schools, social constructions and personal perceptions of spaces affect and reflect peoples' experiences in profound ways. Examining such perceptions has revealed that residents' experiences and memories are heterogeneous, diverse and very personal.

description: Detumbling refers to the act of dampening the angular velocity of the satellite. This operation is of paramount importance since it is virtually impossible to nominally perform any other operation without some degree of attitude control. Common methods used to detumble satellites usually involve magnetic actuation, paired with different types of sensors which are used to provide angular velocity feedback. This paper presents the adverse effects of time-discretization on the stability of two detumbling algorithms. An extensive literature review revealed that both algorithms achieve absolute stability for systems involving continuous feedback and output. However, the physical components involved impose limitations on the maximum frequency of the algorithm, thereby making any such system inconceivable. This asserts the need to perform a discrete-time stability analysis, as it is better suited to reflect on the actual implementation and dynamics of these algorithms. The paper starts with the current theory and views on the stability of these algorithms. The next sections describe the continuous and discrete-time stability analysis performed by the team and the conclusions derived from it. Theoretical investigation led to the discovery of multiple conditions on angular velocity and operating frequencies of the hardware, for which the algorithms were unstable. These results were then verified through various simulations on MATLAB and Python3.6.7. The paper concludes with a discussion on the various instabilities posed by time-discretization and the conditions under which the detumbling algorithm would be infeasible.
Role of Communication in Tackling Developmental Issues: The Birinin Gwari Community Theatre Experience
Creators: name: Ihuoma Okorie
Publisher: name: Zenodo

description: The importance of development to the growth of any nation cannot be overemphasized. Communication, on the other hand, is an indisputable instrument of development hence, for the development goals of a nation to strive, communication has to be put in its proper context; this lies in the fact that communication can be said to be the only viable tool that can be used to bring development to the doorstep of its citizenry. Therefore, for communication to be successful, the decoding process must be an indication of proper understanding. In Nigeria, however, inadequate communication linkages have stood as a bane to development both in the Urban and rural areas coupled with the fact that the people whom development is meant for are often times, excluded from the development process hence, the utmost need to place communication in its proper context for development. In view of the above, this paper focuses on the people which the paper captures as the Natives and their role in the process of communication using a development communication approach and strategy known as Community Theatre. Findings from the paper show that through Community Theatre, the Natives were able to immerse themselves in the development process via participation thus, accentuating the fact that development cannot be devoid of the people whom it is meant for. This, therefore, is a pointer to the fact that strategic communication plays a huge role in development is adequately utilized.

description: We theoretically investigate the optical focusing of a rubidium Bose-Einstein condensate onto a planar surface. Our analysis uses a Gaussian variational method that includes the effects of two-body atom-atom interactions and three-body recombination losses. The essential factors such as the width, peak density and atom loss rate of the focused BEC profile on the surface are investigated and compared to Gross-Pitaevskii numerical simulations. We find a reasonable agreement in the results between our analytical approach and the numerical simulations. Our analysis predicts that condensates of $10^5$ atoms could be focused down to $\sim 10$nm widths, potentially allowing nanometer-scale atomic deposition with peak densities greater than $10^5$ atoms/$μ$m$^2$.

Quasinormal modes and Purcell factors of coupled loss-gain resonators and index-modulated ring resonators near exceptional points

description: We first present a quasinormal mode (QNM) theory for coupled loss-gain resonators working near an exceptional point. Assuming linear media, which can be fully quantified using the complex pole properties of the QNMs, we show how the QNMs yield a quantitatively good model to a full dipole spontaneous emission response in Maxwell's equations at various spatial positions and frequencies (linear response). We also develop a highly accurate and intuitive QNM coupled-mode theory, which can be used to rigorously model such systems using only the QNMs of the bare resonators, where the hybrid QNMs of the complete system are automatically obtained. Near a lossy exceptional point, we analytically show how the QNMs yield a Lorentzian-like and a Lorentzian-squared-like response for the spontaneous emission lineshape, consistent with other works. However, using rigorous analytical and numerical solutions for microdisk resonators, we demonstrate that the general lineshapes are far richer than what has been previously predicted. Indeed, the classical picture of spontaneous emission can take on a wide range of positive and negative Purcell factors from the hybrid modes of the coupled loss-gain system. These negative Purcell factors are unphysical and signal a clear breakdown of the classical dipole picture of spontaneous emission in such media, though the negative local density of states is correct. We also show the rich spectral features of the Green function propagators, which can be used to model various physical observables. Second, we present a QNM approach to model index modulated ring resonators working near an exceptional point and show unusual chiral power flow from linearly polarized emitters, in agreement with recent experiments, which is quantitatively explained without invoking the interpretation of a missing dimension (the Jordan vector) and a decoupling from the cavity eigenmodes.

Investigation of the effect of in vivo inhibition of dipeptidyl peptidase IV (DP IV) on glucose tolerance in Zucker rats and of DP IV expression in pancreatic beta cells
Creators: name: White, Heather Ann
Publisher: name: University of British Columbia
Year: 2009

description: Glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) are two hormones released from the gut post-prandially which act at the pancreatic β cell to potentiate glucose-induced insulin secretion. DP IV is the primary enzyme responsible for the cleavage and inactivation of the incretins and it is known that inhibition of the enzyme by the specific inhibitor Isoleucine-thiazolidide (Ile-thiazolidide), prevents degradation of GIP and GLP-1. It was hypothesised that inhibition of the enzyme would prolong the biological half-lives of the incretins, thereby enhancing insulin release post-prandially and improving glucose tolerance. In addition to the circulation, a site where a portion of this proteolysis occurs may be the β-cell, the incretin target tissue. DP IV has been previously localised to the pancreatic islets and specifically to the α-cells, and its presence has yet to be demonstrated in the β-cell. Using conscious, unrestrained Zucker rats (n=6) Ilethiazolidide was administered (20 μmol) simultaneously with an oral glucose challenge (OGTT) and resulted in rapid and sustained inhibition of DP IV activity in obese and lean animals. The integrated insulin response in both phenotypes was significantly different between the inhibitor-treated and control groups (obese, 1696.6 ± 80.1 vs. 725.5 ± 88.3 μU, respectively; lean, 2324.1 ± 177.4 vs. 1890.8 ± 67.9 μU, respectively). The integrated glucose response to an OGTT was reduced by 39% in inhibitor-treated obese animals versus 22% in treated lean rats. Pre-treatment of animals with Ile-thiazolidide, Pro-Ile-thiazolidide or Gly-Pro-Ile-thiazolidide prior to OGTT significantly inhibited DP IV activity as before and resulted in a more rapid insulin response compared to the previous protocol. Gly-Pro-Ile thiazolidide demonstrated the greatest effect on insulin secretion with a peak of 218.0 ± 22.5 μU/ml. Pro-Ile-thiazolidide and Gly-Pro-Ile-thiazolidide improved glucose tolerance in obese rats while Ile-thiazolidide did not. Due to a possible "priming" effect on the enteroinsular axis by pre-treatment with inhibitor, this protocol was of greater value in improving glucose handling in the obese Zucker rat, a model of NIDDM. In an attempt to localise DP IV to the β cell, pancreata from lean and obese Zucker rats, and DP IV-negative rats were fixed in paraformaldehyde and cryosectioned (20 μm). Sections were double stained for insulin and DP IV and visualised using fluorescence microscopy. Double labelling was observed in both phenotypes with no difference between the two. These results indicate that DP IV is expressed in the pancreatic β-cell and may be co-secreted with insulin where it could cleave and inactivate the incretin hormones at their target cell.

description: We propose a decentralized game-theoretic framework for dynamic task allocation problems for multi-agent systems. In our problem formulation, the agents' utilities depend on both the rewards and the costs associated with the successful completion of the tasks assigned to them. The rewards reflect how likely is for the agents to accomplish their assigned tasks whereas the costs reflect the effort needed to complete these tasks (this effort is determined by the solution of corresponding optimal control problems). The task allocation problem considered herein corresponds to a dynamic game whose solution depends on the states of the agents in contrast with classic static (or single-act) game formulations. We propose a greedy solution approach in which the agents negotiate with each other to find a mutually agreeable (or individually rational) task assignment profile based on evaluations of the task utilities that reflect their current states. We illustrate the main ideas of this work by means of extensive numerical simulations.

description: The planar Hall effect (PHE), wherein a rotating magnetic field in the plane of a sample induces oscillating transverse voltage, has recently garnered attention in a wide range of topological metals and insulators. The observed twofold oscillations in $ρ_{yx}$ as the magnetic field completes one rotation are the result of chiral, orbital and/or spin effects. The antiperovskites $A_3B$O ($A$ = Ca, Sr, Ba; $B$ = Sn, Pb) are topological crystalline insulators whose low-energy excitations are described by a generalized Dirac equation for fermions with total angular momentum $J = 3/2$. We report unusual sixfold oscillations in the PHE of Sr$_3$SnO, which persisted nearly up to room temperature. Multiple harmonics (twofold, fourfold and sixfold), which exhibited distinct field and temperature dependencies, were detected in $ρ_{xx}$ and $ρ_{yx}$. These observations are more diverse than those in other Dirac and Weyl semimetals and point to a richer interplay of microscopic processes underlying the PHE in the antiperovskites.

On Hawking Radiation as Tunneling with Logarithmic Corrections

description: There has been recent speculation that the tunneling paradigm for Hawking radiation could -- after quantum-gravitational effects have suitably been incorporated -- provide a means for resolving the (black hole) information loss paradox. A prospective quantum-gravitational effect is the logarithmic-order correction to the Bekenstein-Hawking entropy/area law. In this letter, it is demonstrated that, even with the inclusion of the logarithmic correction (or, indeed, the quantum correction up to any perturbative order), the tunneling formalism is still unable to resolve the stated paradox. Moreover, we go on to show that the tunneling framework effectively constrains the coefficient of this logarithmic term to be non-negative. Significantly, the latter observation implies the necessity for including the canonical corrections in the quantum formulation of the black hole entropy.

description: As a large-area crop, silage maize (Zea mays L.) needs cultivation methods that make it possible to grow the crop in a more environmentally friendly way without sacrificing yield. One way to reduce the risk of erosion, increase biodiversity in the stand and improve nitrogen utilisation can be through mixed cropping. The combination of maize and runner beans (Phaseolus vulgaris var. vulgaris), which originated in Latin America, has this potential and has been the subject of more intensive research in West-Central Europe for several years. Der Silomais (Zea mays L.) als flächenstarke Kultur benötigt Anbauverfahren, die es ermöglichen, die Kultur ohne Ertragseinbußen umweltverträglicher anzubauen. Ein Weg, das Erosionsrisiko zu reduzieren, die Artenvielfalt im Bestand zu erhöhen und die Stickstoffausnutzung zu verbessern, kann der Gemengeanbau sein. Die aus Lateinamerika stammende Kombination von Mais und Stangenbohnen (Phaseolus vulgaris var. vulgaris) hat dieses Potenzial und wird seit einigen Jahren in Westmitteleuropa intensiver erforscht.

description: We study the driven collective dynamics of a colloidal monolayer sedimentating down an inclined plane. The action of the gravity force parallel to the bottom wall creates a flow around each colloid, and the hydrodynamic interactions among the colloids accelerate the sedimentation as the local density increases. This leads to the creation of a universal "triangular" inhomogeneous density profile, with a traveling density shock at the leading front moving in the downhill direction. Unlike density shocks in a colloidal monolayer driven by applied torques rather than forces [Phys. Rev. Fluids, 2(9):092301, 2017], the density front during sedimentation remains stable over long periods of time even though it develops a roughness on the order of tens of particle diameters. Through experimental measurements and particle-based computer simulations, we find that the Burgers equation can model the density profile along the sedimentation direction as a function of time remarkably well, with a modest improvement if the nonlinear conservation law accounts for the sub-linear dependence of the collective sedimentation velocity on density.

description: We present our results of deep 21 cm line (HI) observations of five early and mixed-type dwarf galaxies in the nearby Sculptor group using the ATNF 64m Parkes Radio Telescope. Four of these objects, ESO294-G010, ESO410-G005, ESO540-G030, and ESO540-G032, were detected in HI with neutral hydrogen masses in the range of 2-9x10^5 M_{\odot} ($M_{HI}/L_{B}$ = 0.08, 0.13, 0.16, and 0.18, respectively). These HI masses are consistent with the gas mass expected from stellar outflows over a large period of time. Higher resolution radio data from the Australia Telescope Compact Array were further analysed to measure more accurate positions and the distribution of the HI gas. In the cases of dwarfs ESO294-G010 and ESO540-G030, we find significant offsets of 290 pc and 460 pc, respectively, between the position of the HI peak flux and the center of the stellar component. These offsets are likely to have internal cause such as the winds from star-forming regions. The fifth object, the spatially isolated dwarf elliptical Scl-dE1, remains undetected at our 3σlimit of 22.5 mJy km/s and thus must contain less than 10^5 M_{\odot} of neutral hydrogen. This leaves Scl-dE1 as the only Sculptor group galaxy known where no interstellar medium has been found to date. The object joins a list of similar systems including the Local Group dwarfs Tucana and Cetus that do not fit into the global picture of the morphology-density relation where gas-rich dwarf irregulars are in relative isolation and gas-deficient dwarf ellipticals are satellites of more luminous galaxies.

description: This paper surveys visualization and interaction techniques for geospatial networks from a total of 95 papers. Geospatial networks are graphs where nodes and links can be associated with geographic locations. Examples can include social networks, trade and migration, as well as traffic and transport networks. Visualizing geospatial networks poses numerous challenges around the integration of both network and geographical information as well as additional information such as node and link attributes, time, and uncertainty. Our overview analyzes existing techniques along four dimensions: i) the representation of geographical information, ii) the representation of network information, iii) the visual integration of both, and iv) the use of interaction. These four dimensions allow us to discuss techniques with respect to the trade-offs they make between showing information across all these dimensions and how they solve the problem of showing as much information as necessary while maintaining readability of the visualization. https://geonetworks.github.io.

description: Generating natural language under complex constraints is a principled formulation towards controllable text generation. We present a framework to allow specification of combinatorial constraints for sentence generation. We propose TSMH, an efficient method to generate high likelihood sentences with respect to a pre-trained language model while satisfying the constraints. Our approach is highly flexible, requires no task-specific training, and leverages efficient constraint satisfaction solving techniques. To better handle the combinatorial constraints, a tree search algorithm is embedded into the proposal process of the Markov chain Monte Carlo (MCMC) to explore candidates that satisfy more constraints. Compared to existing MCMC approaches, our sampling approach has a better mixing performance. Experiments show that TSMH achieves consistent and significant improvement on multiple language generation tasks.

description: A method is presented for tracing the locus of a specific peak in the frequency response under variation of a parameter. It is applicable to periodic, steady-state vibrations of harmonically forced nonlinear mechanical systems. It operates in the frequency domain and its central idea is to assume a constant phase lag between forcing and response. The method is validated for a two-degree-of-freedom oscillator with cubic spring and a bladed disk with shroud contact. The method provides superior computational efficiency, but is limited to weakly-damped systems. Finally, the capability to reveal isolated solution branches is highlighted.

description: The proton--proton elastic differential cross section at very small four momentum transfer squared has been measured at three different incident proton momenta in the range of 2.5 to 3.2 GeV/c by detecting the recoil proton at polar angles close to $90^\circ$. The measurement was performed at COSY with the KOALA detector covering the Coulomb-nuclear interference region. The total cross section $σ_\text{tot}$, which has been determined precisely, is consistent with previous measurements. The values of the slope parameter $B$ and the relative real amplitude ratio $ρ$ determined in this experiment alleviate the lack of data in the relevant energy region. This precise data on $ρ$ might be an important check for a new dispersion analysis.

description: A Hadron Blind Detector (HBD) is being developed for the PHENIX experiment at RHIC. It consists of a Cherenkov radiator operated with pure CF4 directly coupled in a windowless configuration to a triple-GEM detector element with a CsI photocathode and pad readout. The HBD operates in the bandwidth 6-11.5 eV(110-200 nm). We studied the detector response to minimum ionizing particles and to electrons. We present measurements of the CsI quantum efficiency, which are in very good agreement with previously published results over the bandwidth 6-8.3 eV and extend them up to 10.3 eV. Discharge probability andaging studies of the GEMs and the CsI photocathode in pure CF4 are presented.

Architects & sustainability in the context of conventional project delivery: the degree and appropriateness of environmentally responsive design
Creators: name: Wright, Christopher Charles
Publisher: name: University of British Columbia
Year: 2009

description: There is evidence that industrialized societies are consuming resources and discharging more waste than the earth can produce and absorb. These are brought about by the behaviour of many unsustainable actions by individuals in the 'consumer society'. They are perpetuated by many interconnected factors and development of land for public and private use is one factor that has neglected the collective costs of development. These collective costs consider ecological and social indicators of the 'health' of society as well as the economic ones of profit or job creation. Clients, prime contractors and architects are the three influential project members that can affect significant changes in land use and building, depending on their understanding of the conventional delivery process and the applicability of alternate, more responsible processes. To understand how architects can positively and directly influence this move away from unsustainable practices in conventional project development, the project members and their responsibilities are defined. Also, the alternate process of 'environmentally responsible design' (ERD) is developed which lies between conventional design (currently destructive) and 'sustainable' design (an 'ideal' design which respects environmental, social and economic needs and limitations), where the degree of its adoption is dependent on the level of commitment the influential project members. To understand the process of project development and the type of interactions that the project members have with one another during the course of development, numerous interviews were conducted. These revealed the project member's responsibilities, concerns, reservations and insights as they related to environmentally responsive and conventional project delivery processes. Five main conclusions were realized from the research: (1) that currently, environmentally responsive design is not properly understood, marketed or controlled and this lack of understanding is undermining its legitimacy and adoption; (2) that the analysis of the construction industry by environmental groups is not sufficiently complex to provide viable alternatives; (3) that environmental efforts must concentrate on creating self-reinforcing settings that lower the systemic resistance to ERD; (4) that architects, as project coordinators, are best positioned to improve the development process to support ERD; and (5) that architects have a duty to improve the quality of the built environment and need to begin by collectively placing a higher priority on architectural 'craftsmanship' over 'style'.

description: We prepare mixtures of ultracold CaF molecules and Rb atoms in a magnetic trap and study their inelastic collisions. When the atoms are prepared in the spin-stretched state and the molecules in the spin-stretched component of the first rotationally excited state, they collide inelastically with a rate coefficient of $k_2 = (6.6 \pm 1.5) \times 10^{-11}$ cm$^{3}$/s at temperatures near 100~$μ$K. We attribute this to rotation-changing collisions. When the molecules are in the ground rotational state we see no inelastic loss and set an upper bound on the spin relaxation rate coefficient of $k_2 < 5.8 \times 10^{-12}$ cm$^{3}$/s with 95% confidence. We compare these measurements to the results of a single-channel loss model based on quantum defect theory. The comparison suggests a short-range loss parameter close to unity for rotationally excited molecules, but below 0.04 for molecules in the rotational ground state.

description: Quantum toroidal algebras (or double affine quantum algebras) are defined from quantum affine Kac-Moody algebras by using the Drinfeld quantum affinization process. They are quantum groups analogs of elliptic Cherednik algebras (elliptic double affine Hecke algebras) to whom they are related via Schur-Weyl duality. In this review paper, we give a glimpse on some aspects of their very rich representation theory in the context of general quantum affinizations. We illustrate with several examples. We also announce new results and explain possible further developments, in particular on finite dimensional representations at roots of unity.

description: The properties of open quantum system in quantum information science is now extensively investigated more generally by the research community as a fundamental issue for a variety of applications. Usually, the states of the open quantum system might be disturbed by the decoherence which will reduce the fidelity in the quantum information processing. So it is better to eliminate the influence of the environment. However, as part of the composite system, rational use of the environment system could be beneficial to quantum information processing. Here we theoretically studied the environment induced quantum nonlinearity and energy spectrum tuning method in the optomechanical system. And we found that the dissipation coupling of the hybrid dissipation and dispersion optomechanical system can induce the coupling between the environment and system in the cross- Kerr interaction form. When the symmetry is broken with a directional pumping environment, the system exhibits the non-reciprocal behavior during the photon excitation and photon blockade for the clockwise and counterclockwise modes of the whispering-gallery mode microcavity. Furthermore, we believe that the cross-Kerr coupling can also be used in a more widely region in quantum information processing and quantum simulation.

description: We study N=2 supersymmetric quantum mechanics of a charged particle on sphere in the background of Dirac magnetic monopole. We adopt CP(1) model approach in which the monopole interaction is free of singularity. In order to exploit manifest U(1) covariance in the superspace formalism, we introduce a gauge covariant chiral superfield which is annihilated by the gauge covariant superderivative instead of the usual superderivative. We carry out the quantization of the resulting system and compute the quantum mechanical spectrum. We obtain the condition for the spontaneous breaking of supersymmetries explicitely in terms of the monopole charge and a parameter characterizing the operator ordering ambiguity. We find that the supersymmetry is spontaneously broken unless a certain combination of theses quantities satisfies some quantization condition.

Stellar wind structures in the eclipsing binary system IGR J18027-2016

description: IGR J18027-2016 is an obscured high-mass X-ray binary formed by a neutron star accreting from the wind of a supergiant companion with a $\sim$4.57 day orbital period. The source shows an asymmetric eclipse profile that remained stable across several years. We aim at investigating the geometrical and physical properties of stellar wind structures formed by the interaction between the compact object and the supergiant star. In this work we analyse the temporal and spectral evolution of this source along its orbit using six archival XMM-Newton observations and the accumulated Swift/BAT hard X-ray light curve. XMM-Newton light curves show that the source hardens during the ingress and egress of the eclipse, in accordance with the asymmetric profile seen in Swift/BAT data. A reduced pulse modulation is observed on the ingress to the eclipse. We model XMM-Newton spectra by means of a thermally-comptonized continuum (nthcomp) adding two gaussian emission lines corresponding to Fe K$α$ and Fe K$β$. We included two absorption components to account for the interstellar and intrinsic media. We found that the local absorption column outside the eclipse fluctuates uniformly around $\sim$ 6$\times$10$^{22}$~cm$^{-2}$, whereas, when the source enters and leaves the eclipse, the column increases by a factor of $\gtrsim$3, reaching values up to $\sim$35 and $\sim$15$\times 10^{22}$~cm$^{-2}$, respectively. Combining the physical properties derived from the spectral analysis, we propose a scenario where a photo-ionisation wake (mainly) and an accretion wake (secondarily) are responsible for the orbital evolution of the absorption column, the continuum emission and the variability seen at the Fe-line complex.
