description: In this paper we present a temporal and spectral analysis of X-ray data from the XMM and Chandra observations of the ultrasoft and variable Seyfert galaxy RX J1301.9+2747. In both observations the source clearly displays two distinct states in the X-ray band, a long quiescent state and a short flare (or eruptive) state which differs in count rates by a factor of 5--7. The transition from quiescent to flare state occurs in 1--2 ks. We have observed that the quiescent state spectrum is unprecedentedly steep with a photon index Gamma~7.1, and the spectrum of the flare state is flatter with Gamma~4.4. X-rays above 2 keV were not significantly detected in either state. In the quiescent state, the spectrum appears to be dominated by a black body component of temperature about ~30--40 eV, which is comparable to the expected maximum effective temperature from the inner accretion disk. The quiescent state however, requires an additional steep power-law, presumably arising from the Comptonization by transient heated electrons. Optical spectrum from the Sloan Digital Sky Survey shows Seyfert-like narrow lines for RX J1301.9+2747, while the HST imaging reveals a central point source for the object. In order to precisely determine the hard X-ray component, future longer X-ray observations are required. This will help constrain the accretion disk model for RX J1301.9+2747, and shed new light into the characteristics of the corona and accretion flows around black holes.

description: We examine the generating function of the time-integrated energy for the one-dimensional Glauber-Ising model. At long times, the generating function takes on a large-deviation form and the associated cumulant generating function has singularities corresponding to continuous trajec- tory (or "space-time") phase transitions between paramagnetic trajectories and ferromagnetically or anti-ferromagnetically ordered trajectories. In the thermodynamic limit, the singularities make up a whole curve of critical points in the complex plane of the counting field. We evaluate analyti- cally the generating function by mapping the generator of the biased dynamics to a non-Hermitian Hamiltonian of an associated quantum spin chain. We relate the trajectory phase transitions to the high-order cumulants of the time-integrated energy which we use to extract the dynamical Lee-Yang zeros of the generating function. This approach offers the possibility to detect continuous trajectory phase transitions from the finite-time behaviour of measurable quantities.

description: We perform a numerical study of the phase transitions in three-dimensional Z(N) lattice gauge theories at finite temperature for N>4. Using the dual formulation of the models and a cluster algorithm we locate the position of the critical points and study the critical behavior across both phase transitions in details. In particular, we determine various critical indices, compute the average action and the specific heat. Our results are consistent with the two transitions being of infinite order. Furthermore, they belong to the universality class of two-dimensional Z(N) vector spin models.

description: Supersymmetric scenarios with R-parity conservation are becoming very constrained due to the lack of missing energy signals, thus motivating those scenarios with R-parity violation. In view of this, we consider a supersymmetric model with R-parity violation and extended by an anomalous horizontal $U(1)_H$ symmetry, where a self-consistent framework with baryon-number violation is achieved along with a proper supression for lepton number violating dimension-5 operators in order to keep a proton decay safe. With the introduction of right-handed neutrinos both Dirac and Majorana masses can be accommodated within this model. The implications for collider physics are discussed.

description: Obtaining reliable, matched photometry for galaxies imaged by different observatories represents a key challenge in the era of wide-field surveys spanning more than several hundred square degrees. Methods such as flux fitting, profile fitting, and PSF homogenization followed by matched-aperture photometry are all computationally expensive. We present an alternative solution called "synthetic aperture photometry" that exploits galaxy profile fits in one band to efficiently model the observed, PSF-convolved light profile in other bands and predict the flux in arbitrarily sized apertures. Because aperture magnitudes are the most widely tabulated flux measurements in survey catalogs, producing synthetic aperture magnitudes (SYNMAGs) enables very fast matched photometry at the catalog level, without reprocessing imaging data. We make our code public and apply it to obtain matched photometry between SDSS ugriz and UKIDSS YJHK imaging, recovering red-sequence colors and photometric redshifts with a scatter and accuracy as good as if not better than FWHM-homogenized photometry from the GAMA Survey. Finally, we list some specific measurements that upcoming surveys could make available to facilitate and ease the use of SYNMAGs.

A Phenomenological Inquiry into Human Trafficking Survivors’ Experiences of Receiving Narrative Exposure Therapy

Hermeneutic Phenomenological Inquiry

description: The number of individuals trafficked to the UK is increasing year on year and shows no sign of slowing. The risk of mental health problems is increased for survivors of human trafficking compared to the general population. Psychological interventions are being developed and provided by both private and public sector organisations, with the aim of addressing survivors’ mental health needs. However, a review of the relevant literature identified a paucity of studies exploring psychological interventions for survivors of trafficking. Additionally, even fewer studies were identified which privileged the voices of survivors themselves, or examined the wider socio-cultural and political contexts within which their narratives were heard or understood. The present research aimed to explore the lived experience of one specific type of therapy, Narrative Exposure Therapy (NET). Semi-structured online interviews were conducted with six survivors of trafficking who had received NET at the Helen Bamber Foundation, a London-based human rights charity. A hermeneutic phenomenological inquiry inspired by Max van Manen was utilised, as this methodology supported and complemented the personal values of the researcher and those of Counselling Psychology more generally, specifically a commitment to engaging with issues of social injustice. The research found that, from the perspective of the survivors, to both commence, and continue, with NET was an ongoing dilemma. NET was experienced as psychologically and physiologically difficult for individuals. However, these difficulties could be mitigated by the survivors’ desire to achieve a better future, their trust in the therapeutic relationship, and support with other stressful life events outside of therapy. The research aims to provide a platform for these individuals’ narratives to be heard, offering a more rounded representation of the diversity and individuality of survivors of trafficking. Additionally, it can also provide Counselling Psychologists with important insights into the lived experiences of NET, taking into consideration the wider context in order to inform practice when working with survivors of trafficking.

Elliptical galaxies with rapidly decreasing velocity dispersion profiles: NMAGIC models and dark halo parameter estimates for NGC 4494

description: NGC 4494 is one of several intermediate-luminosity elliptical galaxies inferred to have an unusually diffuse dark matter halo. We use the chi^2-made-to-measure particle code NMAGIC to construct axisymmetric models of NGC 4494 from photometric and various kinematic data. The extended kinematics include light spectra in multiple slitlets out to 3.5 R_e, and hundreds of planetary nebulae velocities out to ~7 R_e, thus allowing us to probe the dark matter content and orbital structure in the halo. We use Monte Carlo simulations to estimate confidence boundaries for the halo parameters, given our data and modelling set-up. We find that the true potential of the dark matter halo is recovered within Delta G (merit function)<26 (Delta chi^2<59) at 70% confidence level (C.L.), and within Delta G<32 (Delta chi^2<70) at 90% C.L.. These numbers are much larger than the usually assumed Delta chi^2=2.3 (4.6) for 70% (90%) C.L. for two free parameters, perhaps case-dependent, but calling into question the general validity of the standard assumptions used for halo and black hole mass determinations. The best-fitting models for NGC 4494 have a dark matter fraction of about 0.6\pm0.1 at 5R_e (70% C.L.), and are embedded in a dark matter halo with circular velocity ~200 km/s. The total circular velocity curve (CVC) is approximately flat at v_c=220 km/s outside ~0.5R_e. The orbital anisotropy of the stars is moderately radial. These results are independent of the assumed inclination of the galaxy, and edge-on models are preferred. Comparing with the halos of NGC 3379 and NGC 4697, whose velocity dispersion profiles also decrease rapidly from the center outwards, the outer CVCs and dark matter halos are quite similar. NGC 4494 shows a particularly high dark matter fraction inside ~3R_e, and a strong concentration of baryons in the center.

description: The process of complexification is used to classify a Lie algebra and identify its Cartan subalgebra. However, this method does not distinguish between real forms of a complex Lie algebra, which can differ in signature. In this paper, we show how Cartan decompositions of a complexified Lie algebra can be combined with information from the Killing form to identify real forms of a given Lie algebra. We apply this technique to sl(3,O), a real form of e6 with signature (52,26), thereby identifying chains of real subalgebras and their corresponding Cartan subalgebras within e6. Motivated by an explicit construction of sl(3,O), we then construct an abelian group of order 8 which acts on the real forms of e6, leading to the identification of 8 particular copies of the 5 real forms of e6, which can be distinguished by their relationship to the original copy of sl(3,O).

description: Ultrasonic cavitation can be used to improve surface properties of workpieces in industrial applications. During this surface enhancement process, a small gap is required to generate high impact forces on the workpiece surfaces. The distribution of cavitation bubbles, the optimal gap width and the process time highly affect the treated surface properties. In this thesis, the distribution of sound fields in the small gaps and the optimal standoff distance are simulated with the consideration of bubble interactions. Then, sonochemiluminescence and surface volume variation experiments are carried out. Additionally, a piezoelectric force sensor is designed to detect impact forces. Finally, plastic deformation volume is studied to more accurately identify the optimal process time. The simulation and experimental results show good agreements.
title: Analysis of Surface Integrity in Machining of CFRP Under Different Cooling Conditions
Creators: name: Nagaraj, Arjun
Publisher: name: University of Kentucky Libraries
Year: 2019

description: Carbon Fiber Reinforced Polymers (CFRP) are a class of advanced materials widely used in versatile applications including aerospace and automotive industries due to their exceptional physical and mechanical properties. Owing to the heterogenous nature of the composites, it is often a challenging task to machine them unlike metals. Drilling in particular, the most commonly used process for component assembly is critical especially in the aerospace sector which demands parts of highest quality and surface integrity.
Conventionally, all composites are machined under dry conditions. While there are drawbacks related to dry drilling, for example, poor surface roughness, there is a need to develop processes which yield good quality parts. This thesis investigates the machining performance when drilling CFRP under cryogenic, MQL and hybrid (CryoMQL) modes and comparing with dry drilling in terms of the machining forces, delamination, diameter error and surface integrity assessment including surface roughness, hardness and sub-surface damage analysis. Additionally, the effect of varying the feed rate on the machining performance is examined. From the study, it is concluded that drilling using coolant/ lubricant outperforms dry drilling by producing better quality parts. Also, varying the feed rate proved to be advantageous over drilling at constant feed.

Horizontal or vertical magnetic fields on the quiet Sun: Angular distributions and their height variations

Publisher: name: arXiv
Year: 2013
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Different analyses of identical Hinode SOT/SP data of quiet-sun magnetic fields have in the past led to contradictory answers to the question of whether the angular distribution of field vectors is preferentially horizontal or vertical. These answers have been obtained by combining the measured circular and linear polarizations in different ways to derive the field inclinations. A problem with these combinations is that the circular and linear polarizations scale with field strength in profoundly different ways. Here, we avoid these problems by using an entirely different approach that is based exclusively on the fundamental symmetry properties of the transverse Zeeman effect for observations away from the disk center without any dependence on the circular polarization. Systematic errors are suppressed by the application of a doubly differential technique with the 5247-5250 Å line pair for observations with the ZIMPOL-2 imaging polarimeter on the French THEMIS telescope on Tenerife. This allows us to determine in a model- and resolution-independent way how the angular distribution of the intranetwork magnetic fields changes from being preferentially vertical in the lower and middle photosphere to become preferentially horizontal in the upper photosphere.

description: We prove that the tensor algebra of a C*-correspondence $X$ is Dirichlet if and only if $X$ is a Hilbert bimodule. As a consequence, we point out and fix an error appearing in the proof of a famous result of Duncan. Secondly we answer a question raised by Davidson and Katsoulis concerning tensor algebras and semi-Dirichlet algebras, by giving an example of a Dirichlet algebra that cannot be described as the tensor algebra of any C*-correspondence. Furthermore we show that the adding tail technique, as extended by the author and Katsoulis, applies in a unique way to preserve the class of Hilbert bimodules. The exploitation of these ideas implies that the tensor algebra of row-finite graphs, the tensor algebra of multivariable automorphic $\ca$- dynamics and Peters' semicrossed product of an injective $\ca$-dynamical system have the unique extension property. The two latter provide examples of non-separable operator algebras that admit a Choquet boundary in the sense of Arveson.

The computations are carried out on lattice sizes of 16x16x16x4, at matching parameters of early work of the Bielefeld group. Emphasis is placed on the control of systematic errors, by cross-validating results obtained by use of the Taylor expansion and measurements at imaginary chemical potential. To this end, we generalize the magnetic equation of state to the analysis of the number density, and we extend it to imaginary values of the chemical potential.

description: Ultrasonic (US) wire bonding is a predominating interconnection technique in the microelectronic packaging industry. Despite its long-term usage and wide applications, the mechanisms, especially those of the friction and softening phases, are still unclear more than half a century after its invention. Targeting on reducing the big gap to a good understanding of the mechanisms, this dissertation focuses on the relative motions at the wire/substrate and wire/tool interfaces, and the oxide removal process. In addition, an energy flow model from the electrical input energy to the different energies involved in the mechanisms is developed and quantified. The relative motions at the two interfaces were investigated by a real-time observation system with which the micrometer-motions of the tool and the wire were captured. The motions were then tracked and quantified. In addition, the influences of the process parameters including the normal force, US power and process time were analyzed and the combined effect of the normal force and US power was emphasized. By a further investigation on the changes of the surface topography and elements distribution, it was proved that the relative displacement amplitudes at different locations of the wire/tool interface differ. With the substitution of the metal substrate by a transparent glass, the bonding process was visualized and different areas including the contact, friction, stick, microwelds and oxides areas were detected. The oxide removal process was studied with artificial coatings on either the wire or the substrate. A complete removal process including cracks, detachment, milling and transportation was studied. The transportation further includes penetration, oxide flow, pushing and metal splash. The quantification of energy flows shows that most US energy flows to the vibration induced friction at the two interfaces and the vibration induced formation, deformation and breakage of microwelds. Based on the energy flow to the wire/substrate interface and to the formation of microwelds, the optimal combination of the normal force and the ultrasonic power is determined.

description: We investigate the localization of stiff directed lines with bending energy by a short-range random potential. Using perturbative arguments, Flory arguments, and a replica calculation, we show that a stiff directed line in 1+d dimensions undergoes a localization transition with increasing disorder for $d>2/3$. We demonstrate that this transition is accessible by numerical transfer matrix calculations in 1+1 dimensions and analyze the properties of the disorder-dominated phase. On the basis of the two-replica problem, we propose a relation between the localization of stiff directed lines in 1+d dimensions and of directed lines under tension in 1+3d dimensions, which is strongly supported by identical free energy distributions. This shows that pair interactions in the replicated Hamiltonian determine the nature of directed line localization transitions with consequences for the critical behavior of the Kardar-Parisi-Zhang (KPZ) equation. Furthermore, we quantify how the persistence length of the stiff directed line is reduced by disorder.

description: Rapid gas depressurization leads to gas cooling that is followed by slow gas warming when the cavern is kept idle. The decrease in the temperature of gas depends upon the relative withdrawal rate (in %/day), and cavern size and shape. Gas cooling may result in the onset of tensile stresses at cavern walls and roofs that may generate fractures or cracks. However, in most cases, the depth of penetration of these fractures is small, and they are perpendicular to the cavern wall. The distance between two parallel fractures becomes larger when fractures penetrate deeper into the rock mass, as some fractures stop growing. Fractures form a polygonal pattern. Salt slabs are created, with boundaries formed by the opened fractures. As long as the depth of penetration of the fracture remains small, these slabs remain strongly bonded to the rock mass, and it is believed that, in many cases, their weights are not large enough to allow them to break off the cavern wall.

description: A suite of vast stellar surveys mapping the Milky Way, culminating in the Gaia mission, is revolutionizing the empirical information about the distribution and properties of stars in the Galactic stellar disk. We review and lay out what analysis and modeling machinery needs to be in place to test mechanisms of disk galaxy evolution and to stringently constrain the Galactic gravitational potential, using such Galactic star-by-star measurements. We stress the crucial role of stellar survey selection functions in any such modeling; and we advocate the utility of viewing the Galactic stellar disk as made up from `mono-abundance populations' (MAPs), both for dynamical modeling and for constraining the Milky Way's evolutionary processes. We review recent work on the spatial and kinematical distribution of MAPs, and lay out how further study of MAPs in the Gaia era should lead to a decisively clearer picture of the Milky Way's dark matter distribution and formation history.

description: We present narrow-band [O III]lambda5007 and H-alpha images, as well as long-slit high-resolution echelle spectra of the planetary nebula NGC 6058. Our data reveal that NGC 6058 is a multipolar planetary nebula of about ~45 arcsec in extent and formed by four bipolar outflows that are oriented at different position angles. Assuming homologous expansion for all the structures, and a distance of 3.5 kpc, we obtain polar velocities around ~68 km s^-1 for three of them. The estimated kinematical ages suggest that the three oldest outflows have been ejected in intervals of ~ 1100 and ~ 400 yr during which, the ejection axis has changes its orientation by ~ 60 degrees and ~ 40 degrees, respectively. Although a inner ring-like structure is suggested by the direct images, its kinematics shows that no equatorial ring or toroid exists in the nebula. At the contrary, the long-slit spectra reveal that the ring-like structure corresponds to a fourth outflow that is oriented almost perpendicular to the other three. This fourth outflow is the youngest one and appears to be interacting with the other three, creating a protruding zone that sweeps material in a region almost perpendicular to the major axes of the oldest outflows. This structure also presents two bright arcuate regions along the same direction of the older outflows, and at opposite sides from the central star. From our model, we suggest that NGC 6058 could be anintermediate evolutionary stage between starfish planetary nebulae and multipolar planetary nebula with apparent equatorial lobes.

description: Recent observations constrained the tangential velocity of M31 with respect to the Milky Way (MW) to be v_tan<34.4 km/s and the radial velocity to be in the range v_rad=-109+/- 4.4 km/s (van der Marel et al. 2012). In this study we use a large volume high resolution N-body cosmological simulation (Bolshoi) together with three constrained simulations to statistically study this kinematics in the context of the LCDM. The comparison of the ensembles of simulated pairs with the observed LG at the 1-sigma level in the uncertainties has been done with respect to the radial and tangential velocities, the reduced orbital energy (e_tot), angular momentum (l_orb) and the dimensionless spin parameter, lambda. Our main results are: (i) the preferred radial and tangential velocities for pairs in LCDM are v_rad=-80+/-20 km/s, v_tan=50+/-10 km/s, (ii) pairs around that region are 3 to 13 times more common than pairs within the observational values, (iii) 15%to 24% of LG-like pairs in LCDM have energy and angular momentum consistent with observations while (iv) 9% to 13% of pairs in the same sample show similar values in the inferred dimensionless spin parameter. It follows that within current observational uncertainties the quasi-conserved quantities that characterize the orbit of the LG, i.e. e_tot, r_orb and lambda, do not challenge the standard LCDM model, but the model is in tension with regard to the actual values of the radial and tangential velocities. This might hint to a problem of the LCDM model to reproduce the observed LG.

Provide clarity on DNSH to boost contribution of science & technology
Creators: name: CESAER
Publisher: name: Zenodo
Year: 2022

description: LEUVEN, 19 October 2022 The leading universities of Science and Technology (S&T) united in CESAER welcome the focus of the European Commission on supporting the Green Transition, including the findings from the Technical Expert Group on sustainable finance (TEG) which published its final report introducing an ‘EU Taxonomy’ to advance ‘the transition to a low-carbon, resilient and resource-efficient economy’. The ‘Do No Significant Harm’ (DNSH) principle was introduced in this taxonomy as one of the ‘technical screening criteria’ for economic activities. With the position published today, we (i) point out that the current application of the DNSH principle risks slowing down the contribution of S&T to help tackle local and global challenges, and (ii) provide recommendations towards ensuring that the DNSH principle boosts the contribution of S&T instead. Wendy Sonneveld (Co-Chair of Task Force Sustainable Funding) said: “The DNSH principle is often applied in the context of large, billion-euro financial investment projects with well-developed methodologies for addressing potential environmental harms. “In contrast and in areas such as early-stage research into new and emerging S&T, there is a high degree of uncertainty in potential outcomes and impacts. This large degree of uncertainty follows naturally from the ‘high-risk high-gain’ approach that is foundational for pursuing groundbreaking research and disruptive innovation.”  Christian Gerhardts (Co-Chair of Task Force Sustainable Funding) said: “To make sure the implementation of the DNSH principle supports the laudable intention behind it also in Horizon Europe, it is important that approaches are harmonised and clarifications are made. “To achieve this, we offer our commitment and expertise and stand ready to work together with the European Commission.” Please reference our position using https://doi.org/10.5281/zenodo.7224786 For more information and enquiries, please contact our Deputy Secretary General Mattias Björnmalm.
