description: A new, unbiased Spitzer-MIPS imaging survey (~1.8 square degs) of the young stellar content of the Vela Molecular Cloud-D is presented. The survey is complete down to 5mJy and 250mJy at 24micron (mu) and 70mu, respectively. 849 sources are detected at 24mu and 52 of them also have a 70mu counterpart. The VMR-D region is one that we have already partially mapped in dust and gas millimeter emission, and we discuss the correlation between the Spitzer compact sources and the mm contours. About half of the 24mu sources are located inside the region delimited by the 12CO(1-0) contours (corresponding to only one third of the full area mapped with MIPS) with a consequent density increase of about 100% of the 24mu sources [four times for 70mu ones] moving from outside to inside the CO contours. About 400 sources have a 2MASS counterpart. So we have constructed a Ks vs. Ks-[24] diagram and identified the protostellar population. We find an excess of Class I sources in VMR-D in comparison with other star forming regions. This result is reasonably biased by the sensitivity limits, or, alternatively, may reflect a very short lifetime (<=10^6yr) of the protostellar content in this cloud. The MIPS images have identified embedded cool objects in most of the previously identified starless cores; in addition, there are 6 very young, possibly Class 0 objects identified. Finally we report finding of the driving sources for a set of five out of six very compact protostellar jets previously discovered in near-infrared images.

description: The Projected Configuration Interaction (PCI) method starts from a collection of mean-field wave functions, and builds up correlated wave functions of good symmetry. It relies on the Generator Coordinator Method (GCM) techniques, but it improves the past approaches by a very efficient method of selecting the basis states. We use the same realistic Hamiltonians and model spaces as the Configuration Interaction (CI) method, and compare the results with the full CI calculations in the sd and pf shell. Examples of 24Mg, 28Si, 48Cr, 52Fe and 56Ni are discussed.

From Imperial Science to Post-Patriotism: The Polemics and Ethics of British Imperial History
Creators: name: Gattey, Emma
Publisher: name: Global Histories: A Student Journal
Year: 2021

description: From its inception in the late nineteenth century, British imperial history was intended to provide ideological and practical support for empire. Although this sub-discipline has evolved through multiple theoretical ‘turns’ in recent decades, inflected by the methodological developments in global history, imperial history is still used to naturalise global power structures and geopolitical and economic imparities. As several global and imperial historians have remarked, there are serious ethical challenges associated with yoking history to policy, and to public understandings of the past. To meet these challenges, Richard Drayton and Dane Kennedy have urged academics to adopt a ‘post-patriotic’, self-reflective imperial history, one which transcends ideology. These influential historians have also denounced a scholarly focus on the epistemic violence of empire, arguing that this obscures ‘real’, physical violence. However, these historians’ entreaties are marked by their own positionality, one which focuses on ideological and political battlegrounds between polities and empires, at the expense of a truly global focus on the most pressing planetary conjuncture of our time: climate crisis, and its connections with empire. This essay summarises these debates, as well as recent global histories which have closely analysed the interconnections between empire and climate change, indicating a tipping point in global environmental historiography. Using the concepts of the Great Divergence, postcolonial theory, and ‘climatic orientalism’, several global historians have shown that the two dovetailing forms of violence—epistemic and physical—are mutually reinforcing within the history of empire and climate change. Ultimately, this essay suggests that within existing analytical frameworks, the discipline of global history is well-equipped to assess the complex role of imperialism in causing and intensifying climate change. Thus, global historians ought to continue contributing to this inherently interdisciplinary, transnational field.

A geometric construction of the Riemann scalar curvature in Regge calculus

description: The Riemann scalar curvature plays a central role in Einstein's geometric theory of gravity. We describe a new geometric construction of this scalar curvature invariant at an event (vertex) in a discrete spacetime geometry. This allows one to constructively measure the scalar curvature using only clocks and photons. Given recent interest in discrete pre-geometric models of quantum gravity, we believe is it ever so important to reconstruct the curvature scalar with respect to a finite number of communicating observers. This derivation makes use of a new fundamental lattice cell built from elements inherited from both the original simplicial (Delaunay) spacetime and its circumcentric dual (Voronoi) lattice. The orthogonality properties between these two lattices yield an expression for the vertex-based scalar curvature which is strikingly similar to the corresponding hinge-based expression in Regge calculus (deficit angle per unit Voronoi dual area). In particular, we show that the scalar curvature is simply a vertex-based weighted average of deficits per weighted average of dual areas.

Wilson lines - color charge densities correlators and the production of eta' in the CGC for pp and pA collisions

description: We compute the inclusive differential cross section production of the pseudo-scalar meson eta' in high-energy proton-proton (pp) and proton-nucleus (pA) collisions. We use an effective coupling between gluons and eta' meson to derive a reduction formula that relates the eta' production to a field-strength tensor correlator. For pA collisions we take into account saturation effects on the nucleus side by using the Color Glass Condensate formalism to evaluate this correlator. We derive new results for Wilson line - color charges correlators in the McLerran-Venugopalan model needed in the computation of eta' production. The unintegrated parton distribution functions are used to characterize the gluon distribution inside protons. We show that in pp collisions, the cross section depends on the parametrization of unintegrated parton distribution functions and thus, it can be used to put constraints on these distributions. We also demonstrate that in pA collisions, the cross section is sensitive to saturation effects so it can be utilized to estimate the value of the saturation scale.

Using surface models to alter the geometry of real images
Creators: name: Palmer, Michael Richard
Publisher: name: University of British Columbia
Year: 2010

description: Many applications of image analysis and image processing involve the alteration of the geometry of real images. This thesis presents the theory and implementation of three types of geometrically altered imagery: synthetic orthographic stereo pairs, synthetic perspective stereo pairs, and synthetic airborne scanner imagery. The real image is altered as a function of a corresponding surface model. Included is a determination of surface points which are hidden under the assumed imaging geometry and, in the case of radar systems, a determination of surface points which contribute to pixel layover. In this research, a digital terrain model determines the underlying surface geometry of the real image.

description: Dirac fermions in graphene may experiment dispersive pseudo-Landau levels due to a homogeneous pseudomagnetic field and a position-dependent Fermi velocity induced by strain. In this paper, we study the (semi-classical) dynamics of these particles under such a physical context from an approach of coherent states. For this purpose we use a Landau-like gauge to built Perelomov coherent states by the action of a non-unitary displacement operator $D(α)$ on the fundamental state of the system. We analyze the time evolution of the probability density and the generalized uncertainty principle as well as the Wigner function for the coherent states. Our results show how $x$-momentum dependency affects the motion periodicity and the Wigner function shape in phase space.

description: This paper and the results therein are geared towards building a basic toolbox for calculations in quantum information theory of quasi-free fermionic systems. Various entropy and relative entropy measures are discussed and the calculation of these reduced to evaluating functions on the one-particle component of quasi-free states. The set of quasi-free affine maps on the state space is determined and fully characterized in terms of operations on one-particle subspaces. For a subclass of trace preserving completely positive maps and for their duals, Choi matrices and Jamiolkowski states are discussed.

description: We extend the adversarial/non-stochastic multi-play multi-armed bandit (MPMAB) to the case where the number of arms to play is variable. The work is motivated by the fact that the resources allocated to scan different critical locations in an interconnected transportation system change dynamically over time and depending on the environment. By modeling the malicious hacker and the intrusion monitoring system as the attacker and the defender, respectively, we formulate the problem for the two players as a sequential pursuit-evasion game. We derive the condition under which a Nash equilibrium of the strategic game exists. For the defender side, we provide an exponential-weighted based algorithm with sublinear pseudo-regret. We further extend our model to heterogeneous rewards for both players, and obtain lower and upper bounds on the average reward for the attacker. We provide numerical experiments to demonstrate the effectiveness of a variable-arm play.

description: We consider a D=4 two-twistor lagrangian for a massive particle that incorporates the mass-shell condition in an algebraic way, and extend it to a two-supertwistor model with N=2 supersymmetry and central charge identified with the mass. In the purely supertwistorial picture the two D=4 supertwistors are coupled through a Wess-Zumino term in their fermionic sector. We demonstrate how the kappa-gauge symmetry appears in the purely supertwistorial formulation and reduces by half the fermionic degrees of freedom of the two supertwistors; a formulation of the model in terms of kappa-invariant degrees of freedom is also obtained. We show that the kappa-invariant supertwistor coordinates can be obtained by dimensional (D=6 -> D=4) reduction from a D=6 supertwistor. We derive as well by 6 -> 4 reduction the N=2, D=4 massive superparticle model with Wess-Zumino term introduced in 1982. Finally, we comment on general superparticle models constructed with more than two supertwistors.

description: Protoplanetary disks form through angular momentum conservation in collapsing dense cores. In this work, we perform the first simulations with a maximal resolution down to the astronomical unit (au) of protoplanetary disk formation, through the collapse of 1000 solar mass clumps, treating self-consistently both non-ideal magnetohydrodynamics with ambipolar diffusion as well as radiative transfer in the flux-limited diffusion approximation including stellar feedback. Using the adaptive mesh-refinement code RAMSES, we investigate the influence of the magnetic field on the disks properties with three models. We show that, without magnetic fields, a population dominated by large disks is formed, which is not consistent with Class 0 disk properties as estimated from observations. The inclusion of magnetic field leads, through magnetic braking, to a very different evolution. When it is included, small < 50 au disks represent about half the population. In addition, about ~ 70% of the stars have no disk in this case which suggests that our resolution is still insufficient to preserve the smaller disks. With ambipolar diffusion, the proportion of small disks is also prominent and we report a flat mass distribution around 0.01-0.1 solar mass and a typical disk-to-star mass ratios of ~0.01-0.1. This work shows that the magnetic field and its evolution plays a prominent role in setting the initial properties of disk populations.

description: We present the first analysis of internal coronal mass ejection (CME) structure observed very close to the Sun by the Wide-field Imager for Solar PRobe (WISPR) instrument on board Parker Solar Probe (PSP). The transient studied here is a CME observed during PSP's second perihelion passage on 2019 April 2, when PSP was only 40 R_sun from the Sun. The CME was also well observed from 1 au by the STEREO-A spacecraft, which tracks the event all the way from the Sun to 1 au. However, PSP/WISPR observes internal structure not apparent in the images from 1 au. In particular, two linear features are observed, one bright and one dark. We model these features as two loops within the CME flux rope channel. The loops can be interpreted as bundles of field lines, with the brightness of the bright loop indicative of lots of mass being loaded into those field lines, and with the dark loop being devoid of such mass loading. It is possible that these loops are actually representative of two independent flux rope structures within the overall CME outline.

description: Muon tomography or muography is an emerging imaging technique that uses cosmogenic muons as the radiation source. Due to its diverse range of applications and the use of natural radiation, muography is being applied across many fields such as geology, archaeology, civil engineering, nuclear reactor monitoring, nuclear waste characterization, underground surveys, etc. Muons can be detected using various detector technologies, among which, resistive plate chambers (RPC) are a very cost effective choice. RPCs are planar detectors which use ionization in a thin gas gap to detect cosmic muons, already used since years in major particle accelerator experiments. We have developed a muon telescope (or muoscope) composed of small scale RPCs. The design goal for our muoscope is to be portable and autonomous, in order to take data in places that are not easily accessible. The whole setup is light and compact, such to be easily packed in a car trunk. Individual RPCs are hosted in gas-tight aluminium cases. There is no need for gas bottles, once the chambers are filled. The muoscope can be controlled from a reasonable distance using wireless connection. In this paper, we summarize the guiding principles of our project and present some recent developments and future prospects, including a long-term stability study of the resistivity of the semiconductive coating obtained with serigraphy.

description: these benefits are only partly financially valued by farmers and society.
Against this background we assessed the economic performance of marketable ecosystem
services (ES) and non-marketable ES in contrasting landscapes dominated by agricultural or
agroforestry land use in twelve case study regions in Europe. The focus was on the evaluation
of the annual biomass production as marketable outcomes and groundwater recharge,
nutrient retention, soil preservation, carbon sequestration and pollination as non-marketable
outcomes (Kay et al. 2018). Our findings showed, that agroforestry landscapes had slightly
lower market outputs than agricultural areas if the focus was only on marketable ES. However,
when monetary values for non-marketable ES were included, the relative profitability of
agroforestry landscapes increased. This was due to the fact that nutrient and soil losses were
reduced, and additional benefits could be gained from carbon sequestration. This trend was
of similar relevance in all three major biogeographical regions of Europe (Figure 1).
Our outcomes showed how a market system that includes the value of broader ES would result
in landscapes including multifunctional agroforestry systems and underlined that there is
a critical gap in economic assessments that fails to account for ecological and social benefits.

description: There exists an intriguing relation between genus zero correlation functions in the H^+_3 WZNW model and in Liouville field theory. We provide a path integral derivation of the correspondence and then use our new approach to generalize the relation to surfaces of arbitrary genus g. In particular we determine the correlation functions of N primary fields in the WZNW model explicitly through Liouville correlators with N+2g-2 additional insertions of certain degenerate fields. The paper concludes with a list of interesting further extensions and a few comments on the relation to the geometric Langlands program.

description: Morocco’s African foreign policy is not new, although it features some new characteristics, such as an emphasis on the economy, its reach far beyond traditional francophone African circles, as well as unprecedented number of royal visits across Africa. There are also two non-material aspects to Morocco’s new approach: it comes with a South-South twist and may also indicate an identity shift in Morocco, as it seems that the focus on Africa is replacing the Arab-Islamic orientation that dominated under the late King Hassan II. However, one of main challenges of this policy is Morocco’s dual standing on migration: as the country is increasingly becoming, simultaneously, a sending country, a transit country and a host country for migrants, it faces some difficult choices that risk damaging some of its international alliances.

description: The LIGO Scientific Collaboration (LSC) is developing and running analysis pipelines to search for gravitational-wave transients emitted by astrophysical events such as compact binary mergers or core-collapse supernovae. However, because of the non-Gaussian, non-stationary nature of the noise exhibited by the LIGO detectors, residual false alarms might be found at the end of the pipelines. A critical aspect of the search is then to assess our confidence for gravitational waves and to distinguish them from those false alarms. Both the 'Compact Binary Coalescence' and the 'Burst' working groups have been developing a detection checklist for the validation of candidate-events, consisting of a series of tests which aim to corroborate a detection or to eliminate a false alarm. These tests include for example data quality checks, analysis of the candidate appearance, parameter consistency studies and coherent analysis. In this paper, the general methodology used for candidate validation is presented. The method is illustrated with an example of simulated gravitational-wave signal and a false alarm.

description: The desire to perform information processing, computation, communication, signal generation and related tasks, while dissipating as little energy as possible, has inspired many ideas and paradigms. One of the most powerful among them is the notion of using magnetostrictive nanomagnets as the primitive units of the hardware platforms and manipulating their magnetizations with electrically generated static or time varying mechanical strain to elicit myriad functionalities. This approach has two advantages. First, information can be retained in the devices after powering off since the nanomagnets are non-volatile unlike charge-based devices such as transistors. Second, the energy expended to perform a given task is exceptionally low since it takes very little energy to alter magnetization states with strain. This field is now known as "straintronics", in analogy with electronics, spintronics, valleytronics, etc. We review the recent advances and trends in straintronics, including digital information processing (logic), information storage (memory), domain wall devices operated with strain, control of skyrmions with strain, non-Boolean computing and machine learning with straintronics, signal generation (microwave sources) and communication (ultra-miniaturized acoustic and electromagnetic antennas) implemented with strained nanomagnets, hybrid straintronics-magnonics, and interaction between phonons and magnons in straintronic systems. We identify key challenges and opportunities, and lay out pathways to advance this field to the point where it might become a mainstream technology for energy-efficient systems.

description: The IceCube Neutrino Observatory opened the window on high-energy neutrino astronomy by confirming the existence of PeV astrophysical neutrinos and identifying the first compelling astrophysical neutrino source in the blazar TXS0506+056. Planning is underway to build an enlarged detector, IceCube-Gen2, which will extend measurements to higher energies, increase the rate of observed cosmic neutrinos and provide improved prospects for detecting fainter sources. IceCube-Gen2 is planned to have an extended in-ice optical array, a radio array at shallower depths for detecting ultra-high-energy (>100 PeV) neutrinos, and a surface component studying cosmic rays. In this contribution, we will discuss the simulation of the in-ice optical component of the baseline design of the IceCube-Gen2 detector, which foresees the deployment of an additional ~120 new detection strings to the existing 86 in IceCube over ~7 Antarctic summer seasons. Motivated by the phased construction plan for IceCube-Gen2, we discuss how the reconstruction capabilities and sensitivities of the instrument are expected to progress throughout its deployment.

description: We propose a scheme to engineer an effective spin Hamiltonian starting from a system of electrons confined in micro-Penning traps. By means of appropriate sequences of electromagnetic pulses, alternated to periods of free evolution, we control the shape and strength of the spin-spin interaction. Moreover, we can modify the effective magnetic field experienced by the particle spin. This procedure enables us to reproduce notable quantum spin systems, such as Ising and XY models. Thanks to its scalability, our scheme can be applied to a fairly large number of trapped particles within the reach of near future technology.

Talking Football: Challenging Discrimination and Homophobia
Creators: name: Degele, Nina
Publisher: name: Moving the Social
Year: 2019

description: Football is a common playground for grassroots players, fans, spectators and those whose profession consists of writing about football. I am interested in how non-professional football participants talk about gay (especially male) players and homophobia in football. Moreover, I ask further questions like “how do such talks, conversations and discussions affect sports journalists’ views on football fans and grassroots players?”. The first half of this research took place between 2008 and 2011 and is based on 24 group discussions mainly with non-professional players. The participants cover a broad spectrum from appreciation towards gay football players to hidden and overt homophobia. In 2016, another 24 interviews with 25 German sport (football) journalists in broadcast, radio, print and online media were conducted. All of them acknowledge the acceptance of gay football players in society. This acknowledgement has a timely correlation with the coming out of a German national football player (Thomas Hitzlsperger) in 2014. Media showed the utmost respect for his decision. However, ambivalence between openness and exclusion can also be found in the way journalists position themselves. Their articulation still includes uncertainty towards the right way of dealing with homosexuality in football. As a result, their attitude is shifting between tolerance and acceptance.

The Physical Parameters of Four WC-type Wolf-Rayet Stars in the Large Magellanic Cloud: Evidence of Evolution

description: We present a spectral analysis of four LMC WC-type Wolf-Rayet (WR) stars (BAT99-8, BAT99-9, BAT99-11, and BAT99-52) to shed light on two evolutionary questions surrounding massive stars. The first is: are WO-type WR stars more oxygen enriched than the WC-type stars, indicating further chemical evolution, or are the strong high-excitation oxygen lines in the WO-type stars an indication of higher temperatures. This study will act as a baseline for answering the question of where WO-type stars fall in WR evolution. Each star's spectrum, extending from 1100~Å to 25000~Å, was modeled using \cmfgen\ to determine the star's physical properties such as luminosity, mass-loss rate, and chemical abundances. The oxygen abundance is a key evolutionary diagnostic, and with higher resolution data and an improved stellar atmosphere code, we found the oxygen abundance to be up to a factor of 5 lower than previous studies. The second evolutionary question revolves around the formation of WR stars: Do they evolve by themselves or is a close companion star necessary for their formation? Using our derived physical parameters, we compared our results to the Geneva single-star evolutionary models and the BPASS binary evolutionary models. We found that both the Geneva solar metallicity models and BPASS LMC metallicity models are in agreement with the four WC-type stars, while the Geneva LMC metallicity models are not. Therefore, these four WC4 stars could have been formed either via binary or single-star evolution.
Estimating stellar rotation from starspot detection during planetary transits

description: A new method for determining the stellar rotation period is proposed here, based on the detection of starspots during transits of an extra-solar planet orbiting its host star. As the planet eclipses the star, it may pass in front of a starspot which will then make itself known through small flux variations in the transit light curve. If we are lucky enough to catch the same spot on two consecutive transits, it is possible to estimate the stellar rotational period. This method is successfully tested on transit simulations on the Sun yielding the correct value for the solar period. By detecting two starspots on more than one transit of HD 209458 observed by the Hubble Space Telescope, it was possible to estimate a period of either 9.9 or 11.4 days for the star, depending on which spot is responsible for the signature in the light curve a few transits later. Comparison with period estimates of HD209458 reported in the literature indicates that 11.4 days is the most likely stellar rotation period.

description: The area and perimeter dependence of the Josephson-like interlayer tunneling signature of the coherent $ν_T=1$ quantum Hall phase in bilayer two-dimensional electron systems is examined. Electrostatic top gates of various sizes and shapes are used to locally define distinct $ν_T=1$ regions in the same sample. Near the phase boundary with the incoherent $ν_T=1$ state at large layer separation, our results demonstrate that the tunneling conductance in the coherent phase is closely proportional to the total area of the tunneling region. This implies that tunneling at $ν_T=1$ is a bulk phenomenon in this regime.

description: In this review, we describe and analyze a mesoscale simulation method for fluid flow, which was introduced by Malevanets and Kapral in 1999, and is now called multi-particle collision dynamics (MPC) or stochastic rotation dynamics (SRD). The method consists of alternating streaming and collision steps in an ensemble of point particles. The multi-particle collisions are performed by grouping particles in collision cells, and mass, momentum, and energy are locally conserved. This simulation technique captures both full hydrodynamic interactions and thermal fluctuations. The first part of the review begins with a description of several widely used MPC algorithms and then discusses important features of the original SRD algorithm and frequently used variations. Two complementary approaches for deriving the hydrodynamic equations and evaluating the transport coefficients are reviewed. It is then shown how MPC algorithms can be generalized to model non-ideal fluids, and binary mixtures with a consolute point. The importance of angular-momentum conservation for systems like phase-separated liquids with different viscosities is discussed. The second part of the review describes a number of recent applications of MPC algorithms to study colloid and polymer dynamics, the behavior of vesicles and cells in hydrodynamic flows, and the dynamics of viscoelastic fluids.

description: Rashba interfaces yield efficient spin-charge interconversion and give rise to nonreciprocal transport phenomena. Here, we report magnetotransport experiments in few-nanometer-thick films of PdCoO$_2$, a delafossite oxide known to display a large Rashba splitting and surface ferromagnetism. By analyzing the angle dependence of the first- and second-harmonic longitudinal and transverse resistivities, we identify a Rashba-driven unidirectional magnetoresistance that competes with the anomalous Nernst effect below the Curie point. We estimate a Rashba coefficient of 0.75 {\pm} 0.3 eV Å and argue that our results qualify delafossites as a new family of oxides for nano-spintronics and spin-orbitronics, beyond perovskite materials.

Researching the History of Grassroots Football in England: Sources and Opportunities
Creators: name: Porter, Dilwyn
Publisher: name: Moving the Social
Year: 2019

description: Since 1980 there has been an abundance of research into the history of association football in England most of which has focused on the elite professional game and its followers. Recreational football has been relatively neglected, though participant numbers suggest that it constituted — as it still does — a highly significant social and cultural phenomenon. For many thousands in the mid-20th century it was “their most important social activity” (Nicholas Fishwick: English Football and Society 1910 –1950, Manchester, 1989, p. 1). Yet why did so many people play football for small clubs in local leagues, or simply come together for an informal ‘kickabout’ when an opportunity presented itself? The scant historiography on English football at the grassroots suggests that this is a question that sports historians have yet to address systematically. Constructing a satisfactory response involves exploring the archival and newspaper sources already available to historians imaginatively while giving due consideration to the possibilities of previously overlooked autobiographical and literary texts.
