description: ESO has developed a concept for a compact laser guide star unit for use in future Adaptive Optics (AO)
systems. A small powerful laser is combined with a telescope that launches the beam, creating a single
modular unit that can be mounted directly on a large telescope. This approach solves several of the
stability problems experienced with a number of first generation laser guide star systems around the
world. Four of these compact laser guide stars will be used for the new VLT 4LGSF Adaptive Optics
Facility (AOF), to be installed on UT4 in Paranal. The design is passively athermalized over a large
temperature range as well as under the influence of thermal gradients. TNO has developed the laser launch
telescopes and successfully demonstrated its performance under operational conditions. The technology
will also serve as a testbed ahead of the construction of the future European Extremely Large Telescope,
which will also have multiple laser guide star units.

Statistically calibrating comparison metrics of star formation simulations.
Creators: name: Yeremi, Miayan
Publisher: name: University of British Columbia
Year: 2013

description: We have developed an experimentally designed statistical framework, which allows for observation and simulation position-position-velocity cubes to be compared in a systematic manner. The comparison between cubes can be performed using a multitude of metric measures, in particular we have used the following metrics: principal component analysis (PCA), spectral correlation function (SCF), Cramer, and maximum mean discrepancy (MMD). We ran a suite of carefully chosen simulations, and performed a simulation-to-simulation comparison to test the framework in a controlled environment. We have tested the effects of four physical parameters, Mach number, magnetic field, driving scale, and temperature. The developed framework extracted key physics from the optimally designed experiment. In addition, merits of the different measures were highlighted in a standardized manner. After all four metrics were analyzed, we have concluded that PCA, Cramer and MMD respond in a linear manner to changes in factor settings, where as SCF displayed signs of curvature. Furthermore, all four statistics picked out a consistent physical trend, predicting that Mach num- ber, temperature, and Mach-number-temperature interaction are significant dissimilarity drivers. Finally, we propose that this framework will be used in future work for the calibration of simulations to observational data.
Structure of Fermionic Density Matrices: Complete N-representability Conditions

description: We present a constructive solution to the N-representability problem---a full characterization of the conditions for constraining the two-electron reduced density matrix (2-RDM) to represent an N-electron density matrix. Previously known conditions, while rigorous, were incomplete. Here we derive a hierarchy of constraints built upon (i) the bipolar theorem and (ii) tensor decompositions of model Hamiltonians. Existing conditions D, Q, G, T1, and T2, known classical conditions, and new conditions appear naturally. Subsets of the conditions are amenable to polynomial-time computations of strongly correlated systems.

description: Conceptual and feasibility studies of wide field AO systems for Subaru Telescope has been started as
a next generation AO system. Since optical wide field imager, named Hyper Supreme Camera, and multi object
fiber-fed spectrograph, named Prime Focus Spectrograph, are currently under developing for a primary focus of
Subaru Telescope, a wide field imager and spectrograph at near infrared wavelength range with adaptive optics
at Cassegrain or Nasmyth foci must be a complemental instrument in the next future. In this paper, preliminary
performance simulation studies of GLAO and MOAO and science case study in imaging and spectrograph are
introduced. A GLAO simulation tells us that stellar image size is almost uniform up to 20 arcmin FOV. We
found that a number of tip-tilt guide star and its constellation is closely related to the performance of MOAO.
Imaging sensitivity gain is expected about 0.5 magnitude for the point source and 0.3 to 0.4 magnitude for compact
galaxies, whose effective radius is smaller than 3 kpcs at the redshift around 2. On the other hand, the analysis of
a spectroscopy observation to investigate kinematics of high redshift galaxies seems to be not easy using GLAO.
Nonzero $θ_{13}$ and Neutrino Masses from the Modified Tribimaximal Neutrino Mixing Matrix

description: In order to accommodate nonzero and relatively large of mixing angle $θ_{13}$, we modified the tribimaximal mixing(TBM) matrix by introducing a simple perturbation matrix to perturb TBM matrix. The modified TBM can reproduce nonzero mixing angle $θ_{13}=7.9^{0}$ which is in agreement with the present experimental results. By imposing two zeros texture into the obtained neutrino mass matrix from modified TBM, we then have the neutrino mass spectrum in normal hierarchy. Some phenomenological implications are also discussed

Hairy Black Holes in Massive Gravity: Thermodynamics and Phase Structure

description: The thermodynamic properties of a static and spherically symmetric hairy black hole solution arising in massive gravity with spontaneous Lorentz breaking are investigated. The analysis is carried out by enclosing the black hole in a spherical cavity whose surface is maintained at a fixed temperature $T$. It turns out that the ensemble is well-defined only if the "hair" parameter $Q$ characterizing the solution is conserved. Under this condition we compute some relevant thermodynamic quantities, such as the thermal energy and entropy, and we study the stability and phase structure of the ensemble. In particular, for negative values of the hair parameter, the phase structure is isomorphic to the one of Reissner-Nordstrom black holes in the canonical ensemble. Moreover, the phase-diagram in the plan ($Q,T$) has a line of first-order phase transition that at a critical value of $Q$ terminates in a second-order phase transition. Below this line the dominant phase consists of small, cold black holes that are long-lived and may thus contribute much more to the energy density of the Universe than what is observationally allowed for radiating black holes.

description: BaBar's observation of significant deviations of the pion transition form factor (TFF) from the asymptotic expectation with $Q^2>9$ GeV$^2$ has brought a serious crisis to a fundamental picture established for such a simplest $q\bar{q}$ system by perturbative QCD, i.e. the dominance of collinear factorization at high momentum transfers for the pion TFF. We show that non-factorizable contributions due to open flavors in $γγ^*\toπ^0$ could be an important source that contaminates the pQCD asymptotic limit and causes such deviations with $Q^2>9$ GeV$^2$. Within an effective Lagrangian approach, the non-factorizable amplitudes can be related to intermediate hadron loops, i.e. $K^{(*)}$ and $D^{(*)}$ etc, and their corrections to the $π^0$ and $η$ TFFs can be estimated.

title: Legal aspects of environmental issues and equity considerations in the exploitation of oil in Nigeria's Niger delta
Creators: name: Ebeku, Kaniye Samuel Adheledhini
Publisher: name: University of Kent
Year: 2021

description: This thesis examines the legal aspects of environmental and equity issues relating to oil operations in Nigeria's Niger Delta. Oil is Nigeria's chief foreign exchange earner since the early 1970s, accounting for over 90 per cent of her yearly revenue. This natural resource is presently found only in the Niger Delta region of the country, inhabited by indigenous people. The exploitation of this resource is carried on by the Nigerian State in collaboration with oil multi-national companies (MNCs), both of which reap huge revenue and profits, respectively, from the business. On the other hand, oil operations have their negative aspects: adverse environmental and social impacts, and these affect the region (and its biodiversity) and the local inhabitants. Over the last few years, the Niger Delta people have been embarking on frequent protests against oil operations in their region, and are demanding equity. Although previous studies have examined this situation, there has been no systematic study of the environmental and equity issues of the operations, particularly from the perspective of the collective rights of the Niger Delta indigenous people. This thesis is an attempt to fill this gap. Hence, the central question of this thesis is: What is the cause (s) of the present oil-related protests in the Niger Delta? Other research questions include: What is the legal status of the inhabitants of the Niger Delta region? What are the environmental impacts of oil operations in the Niger Delta? And how beneficial have oil operations been to the region and its inhabitants? These will be considered from the perspective of international law relating to indigenous and other collective rights as well as from a socio-legal perspective. Essentially, the thesis argues that contrary to previous studies oil-related environment protection statutes in Nigeria are defective in some respects. However, the major reason for the persistence of oil-related adverse environmental and social impacts is the non-enforcement of relevant laws. Further, it is argued that the operations are inequitable to the Niger Delta people and contrary to their indigenous and other group rights. Lastly, it is argued that the solution to the demands of the people does not lie in token responses, such as the recent establishment of the Niger Delta Development Commission, but in addressing their demands substantively and consistent with fairness and justice, right to development and the recognized and emerging rights of the indigenous people under international law.

title: Scotland and the alternative disposal: Thinking differently?
Creators: name: McManus, Dan
Publisher: name: University of Glasgow
Year: 2021

description: Since its introduction to Scotland, the system of alternatives to prosecution has grown significantly both in terms of use and in the widening of available alternative measures. Despite this, there has been very little research carried out on alternative measures in Scotland. What will follow is a comparative study of the Scottish system with the system of the Netherlands. Prior to recent changes, the Netherlands’ system operated a model similar to that of Scotland but now operates a significantly more comprehensive range of alternatives to court prosecutions. It is concluded that alternatives to prosecution are imperative in a rounded justice system, but there are areas of development that may be feasible to improve the system in Scotland. In addition, recommendations are made for such improvements to the current system in Scotland and there is identification of areas for further research.

description: We present a tetraquark interpretation of the charged bottomonium-like states Z+-_b(10610) and Z+-_b(10650), observed by the Belle collaboration in the pi+- Upsilon(nS) (n=1,2,3) and pi+- h_b(mP) (m=1,2) invariant mass spectra from the data taken near the peak of the Upsilon(5S). In this framework, the underlying processes involve the production and decays of a vector tetraquark Y_b(10890), e+e- --> Y_b(10890) --> [Z+-_b(10610)pi-+, Z+-_b(10650)pi-+] followed by the decays [Z+-_b (10610), Z+-_b (10650)] --> pi+- Upsilon(nS), pi+- h_b(mP). Combining the contributions from the meson loops and an effective Hamiltonian, we are able to reproduce the observed masses of the Z+-_b(10610) and Z+-_b(10650). The analysis presented here is in agreement with the Belle data and provides crucial tests of the tetraquark hypothesis. We also calculate the corresponding meson loop effects in the charm sector and find them dynamically suppressed. The charged charmonium-like states Z+-_c(3752) and Z+-_c(3882) can be searched for in the decays of the J^{PC}=1^{--} tetraquark state Y(4260) via Y(4260) --> Z+-_c(3752)pi-+ and Y(4260) --> Z+-_c(3882)pi-+, with the subsequent decays (Z+-_c(3752),Z+-_c(3882)) --> (J/psi, h_c)pi+-.

Simultaneity as an Invariant Equivalence Relation

description: This paper deals with the concept of simultaneity in classical and relativistic physics as construed in terms of group-invariant equivalence relations. A full examination of Newton, Galilei and Poincaré invariant equivalence relations in $\R^4$ is presented, which provides alternative proofs, additions and occasionally corrections of results in the literature, including Malament's theorem and some of its variants. It is argued that the interpretation of simultaneity as an invariant equivalence relation, although interesting for its own sake, does not cut in the debate concerning the conventionality of simultaneity in special relativity.

description: The experiments on the impact of the size of magnetite clusters on various magnetic properties (magnetic moment, Curie temperature, blocking temperature etc.) have been carried out. The methods of magnetic separation, centrifuging of water suspensions of biocompatible iron oxide nanoparticles (NPs) allow producing fractions with diameter of nanoparticles in the range of 4÷22 nm. The size of NPs are controlled by the methods of dynamic light scattering (DLS), transmission electron microscopy (TEM) and atomic force microscopy (AFM). For the first time the DLS method is applied in real time to control the size during the process of the separation of the NPs in aqueous suspensions. The changes of the size of NPs cause a shift in the Curie temperature and in the changes in the specific magnetic properties of the iron NPs. The experimental data is interpreted on the basis of Monte Carlo simulations for the classical Heisenberg model with different bulk and surface magnetic moments. It is demonstrated experimentally and by theoretical modeling that magnetic properties of magnetite NPs are determined not only by their sizes, but also by the their surface spin states, while both growing and falling dependences of the magnetic moment (per Fe3O4 formula unit) being possible, depending on the number of magnetic atoms in the nanoparticle. Both NPs clean and covered with a bioresorbable layer clusters have been investigated.

Everyday experiences of national security on the Olympic Peninsula
Creators: name: Barrick, Leigh Christine
Publisher: name: University of British Columbia
Year: 2013

description: The United States-Canada political boundary has long been praised as the most extensive peaceful international border in the world. However, this reputation has shifted considerably in recent years. The US has strengthened its northern border security infrastructure at and between ports of entry, hiring new enforcement personnel and upgrading technology to respond to potential threats emerging from Canada. I analyze this change of United States policy and practice by focusing on one US borderland context: northwestern Washington’s Olympic Peninsula. My analysis is driven by the following questions: (1) how do security tactics respond to specific cross-border threats; and (2) why are some Olympic Peninsula residents contesting securitization? In working through these questions, my objective is to foreground everyday enforcement encounters as constitutive of geopolitics – in other words, to identify how the people and places of the peninsula both impact and are impacted by border practices. I argue that national security tactics make borderland residents on the Olympic Peninsula insecure. More specifically, border policing practices carried out in remote inland areas make both law enforcement officers and peninsula residents targeted for policing feel unsafe, without clearly responding to precise cross-border threats. In response, grassroots groups have organized, questioning the relationship between the mission and everyday practices of the United States Border Patrol in rural areas of the US northern border. Analytically, I draw from materially-grounded feminist theory, basing my argument on two conceptual points of departure – first, that security is embodied; and second, that inequalities are interconnected. Drawing insights from the contestations to securitization on the peninsula, I conclude with a consideration of how national security tactics could be more accountable to the wellbeing of borderland residents.

Exploring changes in functional status while waiting for transcatheter aortic valve implantation
Creators: name: Forman, Jacqueline Marie
Publisher: name: University of British Columbia
Year: 2013

description: As the body ages, there is a natural decline in physical and cognitive abilities. The presence of chronic disease can accelerate this process. Aortic stenosis (AS) is a structural heart disease primarily associated with aging. Untreated patients die within 2 to 5 years following the onset of symptoms. For individuals with multiple co-morbidities, surgical treatment is not an option because of high risk for surgical complications. An innovative and minimally invasive procedure called transcatheter aortic valve implantation (TAVI) has emerged as a safe and viable treatment option for higher risk patients. Because of the rapid disease progression of severe AS and the varying wait-times prior to procedure, it is important to understand changes in functional status while waiting for TAVI. The purpose of this study was to examine the changes in functional status between time of eligibility assessment and TAVI procedure date. Changes in functional status including 5-Metre Gait Speed, Canadian Study of Health and Aging Clinical Frailty Scale and Mini Mental State Examination were evaluated using an exploratory prospective cohort design. Thirty two patients participated in the study with median age 81 (range 64 to 93). Functional status declined between time of assessment and time of TAVI: Gait speed increased by 0.53 seconds (p = 0.01) and Clinical Frailty Scale increased by 0.31 (from 4.3 to 4.6, p = 0.01). Patients who waited longer than six weeks for TAVI (n = 19) had a larger decline in gait speed than patients who waited less than six weeks (n = 10) (0.8 sec vs 0.0 sec, p = 0.04). Patients who were living alone (n =11) had a larger increase in frailty scores compared to patients living with another adult (n = 21) (0.6 vs 0.1, p = 0.05). This study has shown that change in functional status may be an important assessment to monitor while patients are waiting for TAVI. Results may be used to facilitate individualized care and management strategies and inform health care policy to develop evidence based benchmarks for safe wait-times. Future research with larger samples could validate the exploratory findings of this study.

description: Massive clumps within the swept-up shells of bubbles, like that surrounding the galactic HII region RCW 120, have been interpreted in terms of the Collect and Collapse (C&C) mechanism for triggered star formation. The cold, dusty clumps surrounding RCW 120 are arranged in an almost spherical shell and harbour many young stellar objects. By performing high-resolution, three-dimensional SPH simulations of HII regions expanding into fractal molecular clouds, we investigate whether the formation of massive clumps in dense, swept-up shells necessarily requires the C&C mechanism. In a second step, we use RADMC-3D to compute the synthetic dust continuum emission from our simulations, in order to compare them with observations of RCW 120 made with APEX-LABOCA at 870 micron. We show that a distribution of clumps similar to the one seen in RCW 120 can readily be explained by a non-uniform initial molecular cloud structure. Hence, a shell-like configuration of massive clumps does not imply that the C&C mechanism is at work. Rather, we find a hybrid form of triggering, which combines elements of C&C and Radiatively Driven Implosion (RDI). In addition, we investigate the reliability of deriving clump masses from their 870 micron emission. We find that for clumps with more than 100 M_sun the observational estimates are accurate to within a factor of two and that, even at these long wavelengths, it is important to account for the radiative heating from triggered, embedded protostars.

description: We define a Higgs descendant $χ$ to be a particle beyond the standard model whose mass arises predominantly from the vacuum expectation value of the Higgs boson. Higgs descendants arise naturally from new physics whose intrinsic mass scale is unrelated to the electroweak scale. The coupling of $χ$ to the Higgs boson is fixed by the mass and spin of $χ$, yielding a highly predictive setup in which there may be substantial modifications to the properties of the Higgs boson. For example, if the decay of the Higgs boson to $χ$ is kinematically allowed, then this branching ratio is largely determined. Depending on the stability of $χ$, Higgs decays may result in a variety of possible visible or invisible final states. Alternatively, loops of $χ$ may affect Higgs boson production or its decays to standard model particles. If $χ$ is stable dark matter, then the mandatory coupling between $χ$ and the Higgs boson gives a lower bound on the direct detection cross section as a function of the $χ$ mass. We also present a number of explicit models which are examples of Higgs descendants. Finally, we comment on Higgs descendants in the context of the excesses near 125 GeV recently observed at ATLAS and CMS.

description: We investigate here the particle acceleration and collisions with extremely large center of mass energies in a perfectly regular spacetime containing neither singularity nor an event horizon. The ultra-high energy collisions of particles near the event horizon of extremal Kerr blackhole, and also in many other examples of extremal blackholes have been investigated and reported recently. We studied an analogous particle acceleration process in the Kerr and Reissner-Nordstrom spacetimes without horizon, containing naked singularities. Further to this, we show here that the particle acceleration and collision process is in fact independent of blackholes and naked singularities, and can happen in a fully regular spacetime containing neither of these. We derive the conditions on the general static spherically symmetric metric for such a phenomena to happen. We show that in order to have ultra-high energy collisions it is necessary for the norm of the timelike Killing vector to admit a maximum with a vanishingly small but a negative value. This is also a condition implying the presence of a surface with extremely large but nevertheless finite value of the redshift or blueshift. Conditions to have ultrahigh energy collisions and regular center imply the violation of strong energy condition near the center while the weak energy condition is respected in the region around the center. Thus the central region is surrounded by a dark energy fluid. Both the energy conditions are respected at the location where the high energy collisions take place. As a concrete example we then investigate the acceleration process in the spacetime geometry derived by Bardeen which is sourced by a non-liner self-gravitating magnetic monopole.

description: We present the Extended Hipparcos Compilation (XHIP), a database of all stars in the New Reduction of the Hipparcos Catalog extensively cross-referenced with data from a broad survey of presently available sources. The resulting collection uniquely assigns 116,096 spectral classifications, 46,392 radial velocities, and 18,549 homogenized iron abundances [Fe/H] to Hipparcos stars. Stellar classifications from SIMBAD, indications of multiplicity from CCDM or WDS, stellar ages from the Geneva-Copenhagen Survey III, supplemental photometry from 2MASS and SIMBAD, and identifications of exoplanet host stars are also included. Parameters for solar encounters and Galactic orbits are calculated for a kinematically complete subset. Kinetic bias is found to be minimal. Our compilation is available through the Centre de Données astronomiques de Strasbourg (CDS) as Catalog V/137B.

Play, Game, Gender and Sociability on Italiote Vase Painting
Creators: name: Alexandra, Attia
Publisher: name: Zenodo
Year: 2020
Subjects: south italian vases ; iconography ; gender study ; play ; games ; sociability

description: On South italian vase painting, as on attic red figure vases, images seem to be read as reflecting the social and religious dynamics of ancient communities, especially in their gendered dimension. Many vases present generic iconographies involving different groups of mortals, sometimes watched by a winged figure, often identified as Eros. Their interactions are displayed by different kinds of circular elements – phiale or patera, tympanon, fruit, ball or undefined decorative pattern – in various positions, handled or placed in the field. Because of the allusive dimension of iconography depicted on South Italian pottery with interchangeable attributes – meaningful or symbolic –, these evocative images (as play, rite, gift for lovers, aso) are uneasy to interpret. The study of the identity of the protagonists, according to age, gender, social status, as well as of the type of contexts (domestic, public, sacred, and funerary) and of shapes, allows us to grasp a representation of the dynamics of sociability through games in metaphorical spaces.

description: A beam monitor detector prototype based on doped silica fibres coupled to optical fibres has been designed, constructed and tested, mainly for accelerators used in medical applications. Scintillation light produced by Ce and Sb doped silica fibres moving across the beam has been measured, giving information on beam position, shape and intensity. Mostly based on commercial components, the detector is easy to install, to operate and no electronic components are located near the beam. Tests have been performed with a 2 MeV proton pulsed beam at an average current of 0.8 μA. The response characteristics of Sb doped silica fibres have been studied for the first time.

description: Multi-Object Adaptive Optics (MOAO) is an adaptive optics technique in development for Extremely
Large Telescopes and will allow simultaneous observation of up to 20 targets in a several arc-minute field-of-
view. Raven is an MOAO pathfinder developed by the Adaptive Optics Laboratory of the University of Victoria,
in collaboration with the Herzberg Institute of Astrophysics and the Subaru Telescope. Its goal is to demonstrate
that MOAO technical challenges such as open-loop control and calibration are achievable on-sky and also to
deliver science results. The open-loop (OL) approach makes the need for calibration even more crucial. We will
present the specific calibration procedures of Raven in two steps. The first one is to find the command matrices
between the three open-loop wavefront sensors (WFS) with the two deformable mirrors (DM) used to correct the
wavefront on the science paths. Because of the OL, we add components such as a calibration-DM in front of the
whole system and also close-loop WFS behind each DM. We register the DM with the CL-WFS and then the
calibration-DM with all of the five WFS and then compute the command matrices. The goal of the second step is
to remove the field-dependent non-common path aberrations (NCPAs). That task is common in AO systems but
presents a bigger challenge in this case because of the open-loop control and also the moving pick-off arms.
title:  Investigating Privacy Policies using PolicyLint Tool
Creators: name: Camaya, Tricia

description: Organizations essentially inform clients about data collection and sharing practices through privacy policies. Recent research has proposed tools to help users better comprehend these lengthy and intricate legal documents that summarize collection and sharing. However, these instruments have a significant flaw. They overlook the possibility of contradictions within a particular policy. This paper introduces PolicyLint, a tool for analyzing privacy policies that simultaneously considers negation and varying semantic levels of data objects and entities. PolicyLint accomplishes this by using sentence-level natural language processing to automatically create ontologies from a large corpus of privacy policies and capturing both positive and negative statements regarding data collection and sharing. Using PolicyLint, I examined the policies of 300 apps and found that some contained contradictions that could indicate false statements. I manually check 100 contradictions, spotting troubling patterns like the use of misleading presentation, attempts to redefine terms that are commonly understood, and tracking information that is made possible by sharing or collecting data that can be used to derive sensitive information. As a result, automated privacy policy analysis is significantly improved by PolicyLint.

description: Introduction: "Medicine is not an exact science. Treatment modalities vary in accordance with the time limits "This is a proverbial saying from ZACARELLO who recorded the first splenectomy in traumatic cases in 1549. In more than two decades of the last concepts of diagnosis and management of spleen, injuries have changed drastically.
 Spleen to the structure and its anatomic position is the body most often injured BAT in general. In this study, we aim to highlight the causes, progress, diagnosis, and treatment, based on grade impairment and other dependent data.
 Materials and methods: Data are from 35 trauma patients with damage to the spleen, who were submitted to the National Trauma Center Tirana. by periods of 01/07/ - 30/11/2006.
 Results: All patients who received the study are with BAT. From these 65% had injuries to the spleen which was not stabilized by hemodynamic were OM, 35% of patients were treated NOM, 58% of who had unique spleen injury, and 42% of cases the spleen injuries were combined with other intraabdominal organs
 Conclusion: All the degrees of spleen injuries III-V, who arrived was in hemorrhagic shock, that did not respond to intensive care therapy, splenectomy should be on our terms. Spleen injuries that grade I-II of which appear in hemodynamically stable condition must be followed step by step in dynamic with the good harmonized to the clinical data, in accordance with algorithms these data from the literature.
