description: Hydrodynamical simulations are increasingly able to accurately model physical systems on stellar, galactic, and cosmological scales, however, the utility of these simulations is often limited by our ability to directly compare them with the datasets produced by observers: spectra, photometry, etc. To address this problem, we have created Trident}, a Python-based, open-source tool for post-processing hydrodynamical simulations to produce synthetic absorption spectra and related data. Trident} can (i) create absorption-line spectra for any trajectory through a simulated dataset mimicking both background quasar and down-the-barrel configurations, (ii) reproduce the spectral characteristics of common instruments like the Cosmic Origins Spectrograph, (iii) operate across the ultraviolet, optical and infrared using customizable absorption line lists, (iv) trace simulated physical structures directly to spectral features, (v) approximate the presence of ion species absent from the simulation outputs, (vi) generate column density maps for any ion, and (vii) provide support for all major astrophysical hydrodynamical codes. The focus of Trident's development is for using simulated datasets to better interpret observations of the circumgalactic medium (CGM) and intergalactic medium (IGM), but it remains a general tool applicable in other contexts.

description: We study the z=0 gas kinematics, morphology, and angular momentum content of isolated galaxies in a suite of cosmological zoom-in simulations from the FIRE project spanning $M_{\star}=10^{6-11}M_{\odot}$. Gas becomes increasingly rotationally supported with increasing galaxy mass. In the lowest-mass galaxies ($M_{\star}<10^{8}M_{\odot}$), gas fails to form a morphological disk and is primarily dispersion and pressure supported. At intermediate masses ($M_{\star}=10^{8-10}M_{\odot}$), galaxies display a wide range of gas kinematics and morphologies, from thin, rotating disks, to irregular spheroids with negligible net rotation. All the high-mass ($M_{\star}=10^{10-11}M_{\odot}$) galaxies form rotationally supported gas disks. Many of the halos whose galaxies fail to form disks harbor high angular momentum gas in their circumgalactic medium. The ratio of the specific angular momentum of gas in the central galaxy to that of the dark-matter halo increases significantly with galaxy mass, from $j_{\rm gas}/j_{\rm DM}\sim0.1$ at $M_{\star}=10^{6-7}M_{\odot}$ to $j_{\rm gas}/j_{\rm DM}\sim2$ at $M_{\star}=10^{10-11}M_{\odot}$. The reduced rotational support in the lowest-mass galaxies owes to (a) stellar feedback and the UV background suppressing the accretion of high-angular momentum gas at late times, and (b) stellar feedback driving large non-circular gas motions. We broadly reproduce the observed scaling relations between galaxy mass, gas rotation velocity, size, and angular momentum, but may somewhat underpredict the incidence of disky, high-angular momentum galaxies at the lowest observed masses ($M_{\star}=(10^{6}-2\times10^{7})M_{\odot}$). In our simulations, stars are uniformly less rotationally supported than gas. The common assumption that stars follow the same rotation curve as gas thus substantially overestimates galaxies' stellar angular momentum, particularly at low masses.

description: We study the effect of non-standard interactions (NSIs) on the propagation of neutrinos through the Earth matter and how it affects the hierarchy sensitivity of the DUNE experiment. We emphasize on the special case when the diagonal NSI parameter $ε_{ee} = -1$, nullifying the standard matter effect. We show that, if in addition, CP violation is maximal then this gives rise to an exact intrinsic hierarchy degeneracy in the appearance channel, irrespective of the baseline and energy. Introduction of off-diagonal NSI parameter, $ε_{e τ}$, shifts the position of this degeneracy to a different $ε_{ee}$. Moreover the unknown magnitude and phases of the off-diagonal NSI parameters can give rise to additional degeneracies. Overall, given the current model independent limits on NSI parameters, the hierarchy sensitivity of DUNE can get seriously impacted. However, a more precise knowledge on the NSI parameters, specially $ε_{ee}$, can give rise to an improved sensitivity. Alternatively, if NSI exists in nature, and still DUNE shows hierarchy sensitivity, certain ranges of the NSI parameters can be excluded. Additionally, we briefly discussed the implications of $ε_{ee} = -1$ (in the Earth) on MSW effect in the Sun.

description: We study the OPE of correlation functions of local operators in planar N=4 super Yang-Mills theory. The considered operators have an explicit spacetime dependence that is defined by twisting the translation generators with certain R-symmetry generators. We restrict to operators that carry a small number of excitations above the twisted BMN vacuum. The OPE limit of the four-point correlator is dominated by internal states with few magnons on top of the vacuum. The twisting directly couples all spacetime dependence of the correlator to these magnons. We analyze the OPE in detail, and single out the extremal states that have to cancel all double-trace contributions.

description: Motifs are a powerful tool for analyzing physiological waveform data. Standard motif methods, however, ignore important contextual information (e.g., what the patient was doing at the time the data were collected). We hypothesize that these additional contextual data could increase the utility of motifs. Thus, we propose an extension to motifs, contextual motifs, that incorporates context. Recognizing that, oftentimes, context may be unobserved or unavailable, we focus on methods to jointly infer motifs and context. Applied to both simulated and real physiological data, our proposed approach improves upon existing motif methods in terms of the discriminative utility of the discovered motifs. In particular, we discovered contextual motifs in continuous glucose monitor (CGM) data collected from patients with type 1 diabetes. Compared to their contextless counterparts, these contextual motifs led to better predictions of hypo- and hyperglycemic events. Our results suggest that even when inferred, context is useful in both a long- and short-term prediction horizon when processing and interpreting physiological waveform data.

description: We investigate the hidden strange light baryon-meson system. With the resonating-group method, two bound states, $η'-N$ and $ϕ-N$, are found in the quark delocalization color screening model. Focusing on the $ϕ-N$ bound state around 1950\,MeV, we obtain the total decay width of about 4\,MeV by calculating the phase shifts in the resonance scattering processes. To study the feasibility of an experimental search for the $ϕ-N$ bound state, we perform a Monte Carlo simulation of the bound state production with an electron beam and a gold target. In the simulation, we use the CLAS12 detector with the Forward Tagger and the BONUS12 detector in Hall B at Jefferson Lab. Both the signal and the background channels are estimated. We demonstrate that the signal events can be separated from the background with some momentum cuts. Therefore it is feasible to experimentally search for the $ϕ-N$ bound state through the near threshold $ϕ$ meson production from heavy nuclei.

Religion and the legitimation of the state: the development of political thought in contemporary Shi’ism (Case study Iran 1979-2004)
Creators: name: Alsaif, Tawfiq
Publisher: name: University of Westminster
Year: 2005

description: Since the early 1990s, the Middle East has witnessed a renewed interest in the debate over the role of religion in the process of democratization. This study aims to examine the possibility of developing a democratic discourse within the Islamic context. It focuses on the evolution of the political thought in Shi'i Islam in the context of Iran after the Islamic revolution of 1979. The reconciliation between religion and democracy is argued to be a two-phase process: in the first phase, religion is integrated into the state in order to bring about a consensual political system and engage the people in the political process. Then, the religious worldview is developed in line with democracy. The study examines the socio-economic factors behind the emergence of the reformist discourse in Iran in the mid-1990s. It also reviews the evolution of that discourse compared with its conservative rival and highlights their approximate to the principles of democracy. Emphasizing the practical side of religion, the thesis concludes that the community's perception and application of the religious teachings have varied over the history to reflect the changing realities of the social life, far from the claim of religion being a fixed order of dogmas. The past twenty-five years witnessed major steps towards adapting the religious values to the modern patterns of socialization and politics. It was set off by the need of unifying the religious and political authorities within the state system. Later, the process was driven by the structural transformations ensued from the revolution and the state policies during the 1980s. The final phase came through the reformist's strategy to democratize the Islamic regime in the late 1990s. My general conclusion is that despite the tremble of the political reform, considerable works have been done, particularly on the structural level. The experience of the reformist rule indicates the possibility of developing a model of democracy appropriate to the local culture, especially the religious beliefs. It also indicates the capacity of the Islamic Republic to develop a democratic character, at least on the long term.

description: We consider two statistical problems at the intersection of functional and non-Euclidean data analysis: the determination of a Fréchet mean in the Wasserstein space of multivariate distributions; and the optimal registration of deformed random measures and point processes. We elucidate how the two problems are linked, each being in a sense dual to the other. We first study the finite sample version of the problem in the continuum. Exploiting the tangent bundle structure of Wasserstein space, we deduce the Fréchet mean via gradient descent. We show that this is equivalent to a Procrustes analysis for the registration maps, thus only requiring successive solutions to pairwise optimal coupling problems. We then study the population version of the problem, focussing on inference and stability: in practice, the data are i.i.d. realisations from a law on Wasserstein space, and indeed their observation is discrete, where one observes a proxy finite sample or point process. We construct regularised nonparametric estimators, and prove their consistency for the population mean, and uniform consistency for the population Procrustes registration maps.

description: The city has proven to be the most successful form of human agglomeration and provides wide employment opportunities for its dwellers. As advances in robotics and artificial intelligence revive concerns about the impact of automation on jobs, a question looms: How will automation affect employment in cities? Here, we provide a comparative picture of the impact of automation across U.S. urban areas. Small cities will undertake greater adjustments, such as worker displacement and job content substitutions. We demonstrate that large cities exhibit increased occupational and skill specialization due to increased abundance of managerial and technical professions. These occupations are not easily automatable, and, thus, reduce the potential impact of automation in large cities. Our results pass several robustness checks including potential errors in the estimation of occupational automation and sub-sampling of occupations. Our study provides the first empirical law connecting two societal forces: urban agglomeration and automation's impact on employment.

description: We show that the cosupport of a commutative noetherian ring is precisely the set of primes appearing in a minimal pure-injective resolution of the ring. As an application of this, we prove that every countable commutative noetherian ring has full cosupport. We also settle the comparison of cosupport and support of finitely generated modules over any commutative noetherian ring of finite Krull dimension. Finally, we give an example showing that the cosupport of a finitely generated module need not be a closed subset of $\operatorname{Spec}(R)$, providing a negative answer to a question of Sather-Wagstaff and Wicklein.

description: Theories with more than one vacuum allow quantum transitions between them, which may proceed via bubble nucleation; theories with more than two vacua posses additional decay modes in which the wall of a bubble may further decay. The instantons which mediate such a process have $O(3)$ symmetry (in four dimensions, rather than the usual $O(4)$ symmetry of homogeneous vacuum decay), and have been called `barnacles'; previously they have been studied in flat space, in the thin wall limit, and this paper extends the analysis to include gravity. It is found that there are regions of parameter space in which, given an initial bubble, barnacles are the favoured subsequent decay process, and that the inclusion of gravity can enlarge this region. The relation to other heterogeneous vacuum decay scenarios, as well as some of the phenomenological implications of barnacles are briefly discussed.

description: A non-equilibrium theory of optical conductivity of dirty-limit superconductors and commensurate charge density wave is presented. We discuss the current response to different experimentally relevant light-field probe pulses and show that a single frequency definition of the optical conductivity $σ(ω)\equiv j(ω)/E(ω)$ is difficult to interpret out of the adiabatic limit. We identify characteristic time domain signatures distinguishing between superconducting, normal metal and charge density wave states. We also suggest a route to directly address the instantaneous superfluid stiffness of a superconductor by shaping the probe light field.

Resilience and vulnerability: Supporting the integration of unaccompanied asylum-seeking minors in the United Kingdom
Creators: name: Wells, Mike
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Applied and developmental psychology not elsewhere classified

description: There is a general agreement in the existing research that unaccompanied asylum-seeking minors (UAMs) are a particularly vulnerable group as a result of their traumatic experiences of forced migration and displacement (Weine et al., 2014; Thommessen et al., 2013; Chase, 2013). The characterization of UAMs as vulnerable has fundamentally shaped the way health and social care professionals respond to the mental health needs and wellbeing of UAMs. Yet, whilst it is clear that UAMs are vulnerable because they face plethora of challenges linked to their past traumatic experiences and present resettlement-related stressors, the evidence suggests that most of these minors show resilience (Ni Raghallaigh and Gilligan, 2010; Chase et al., 2008). This study contributes to the theoretical and empirical exploration of the concepts of the vulnerability and resilience of UAMs as they integrate in the host community of resettlement in the UK. Based on a socio-ecological paradigm, this project aimed to explore the perspectives of UAMs on the protective factors that foster resilience among them that will inform the development of an evidence-based psychosocial intervention with a dual foci of resilience enhancement and psychological distress reduction in UAMs. A three stage mixed methods exploratory design was utilized: 1) systematic review of protective factors and processes of resilience among asylum-seeking and refugee adolescents; 2) qualitative study of UAMs' perspective on protective factors that foster resilience; 3) six months evaluation of the Taking Part (TP) manualized psychosocial intervention for resilience building of UAMs. Results indicated that the TP intervention was effective at enhancing resilience and reducing psychological distress in the participants. Moderate effect sizes were found for the TP intervention, and it presents a feasible and effective psychosocial approach to fostering resilience among UAMs that may facilitate their integration in the host community of resettlement. Longitudinal mixed methods study is needed to further assess the TP intervention effectiveness and scalability.

description: Thin shells are characterized by a high cost of stretching compared to bending. As a result isometries of the midsurface of a shell play a crucial role in their mechanics. In turn, curves with zero normal curvature play a critical role in determining the number and behavior of isometries. In this paper, we show how the presence of these curves results in a decrease in the number of linear isometries. Paradoxically, shells are also known to continuously fold more easily across these rigidifying curves than other curves on the surface. We show how including nonlinearities in the strain can explain this phenomena and demonstrate folding isometries with explicit solutions to the nonlinear isometry equations. In addition to explicit solutions, exact geometric arguments are given to validate and guide our analysis in a coordinate free way.
Using the Internet for religion: a study of the possible use of the Internet for religious purposes among the Catholics of the Archdiocese of Mumbai, India
Creators: name: Botelho, Jude
Publisher: name: University of Westminster
Year: 2005

description: It has been claimed that the Internet is influencing not only ways of doing business and modes of communication and recreation, but also the ways human beings practice religion. Most studies undertaken on how people are using the web for their religious needs are done in North America, largely among Christians. This study was aimed at testing whether this was true of Catholic users of the Internet from the Archdiocese of Mumbai, India. In order to verify the religious use of the Internet, focus groups were conducted among various sectors of Catholic users to explore whether differences in age, sex and religious groupings resulted in significant variations in net usage. The data obtained from the focus groups was further tested with a survey questionnaire, administered to a representative sampling of Catholics from the Archdiocese of Mumbai. The data provides not only general trends of net use among the Catholics, but also nuanced perceptions of the net in relationship to its religious use. Research evidence indicated that the Internet was not being used for religion by the Catholics of Mumbai. The fact that there was an inclination towards and ambivalence to using the net shows that there are deeper issues that are influencing net usage. These issues could relate to the free-for-all style of the net and the authority-bound character of the Catholic faith; the interactive character of the net in contrast to the top-down style of communication of the Catholic church; and the global virtual community of the net in comparison with the tangible faith commitment to the local parish community in worship and practice. In conclusion hypotheses proposed to explain the poor usage of the Net are substantiated and new issues suggested, that require further research in the context of net use for religion.

description: Superconducting transmon qubits comprise one of the most promising platforms for quantum information processing due to their long coherence times and to their scalability into larger qubit networks. However, their weakly anharmonic spectrum leads to spectral crowding in multiqubit systems, making it challenging to implement fast, high-fidelity gates while avoiding leakage errors. To address this challenge, we use a protocol known as SWIPHT [Phys. Rev. B 91, 161405(R) (2015)], which yields smooth, simple microwave pulses designed to suppress leakage without sacrificing gate speed through spectral selectivity. Here, we determine the parameter regimes in which SWIPHT is effective and demonstrate that in these regimes it systematically produces two-qubit gate fidelities for cavity-coupled transmons in the range 99.6%-99.9% with gate times as fast as 23 ns. Our results are obtained from full numerical simulations that include current experimental levels of relaxation and dephasing. These high fidelities persist over a wide range of system parameters that encompass many current experimental setups and are insensitive to small parameter variations and pulse imperfections.

Our optical spectroscopy newly confirm 21 bright LAEs with clear Lya emission, and contribute to make a spectroscopic sample of 96 LAEs at z=6-7 in SILVERRUSH. From the spectroscopic sample, we select 7 remarkable LAEs as bright as Himiko and CR7 objects, and perform deep Keck/MOSFIRE and Subaru/nuMOIRCS near-infrared spectroscopy reaching the 3sigma-flux limit of ~ 2x10^{-18} erg s-1 for the UV-nebular emission lines of He II1640, C IV1548,1550, and O III]1661,1666. Except for one tentative detection of C IV, we find no strong UV-nebular lines down to the flux limit, placing the upper limits of the rest-frame equivalent widths (EW_0) of ~2-4 A for He II, C IV, and O III] lines. Here we also investigate the VLT/X-SHOOTER spectrum of CR7 whose 6 sigma detection of He II is claimed by Sobral et al. Although two individuals and the ESO-archive service carefully re-analyze the X-SHOOTER data that are used in the study of Sobral et al., no He II signal of CR7 is detected, supportive of weak UV-nebular lines of the bright LAEs even for CR7. Spectral properties of these bright LAEs are thus clearly different from those of faint dropouts at z~7 that have strong UV-nebular lines shown in the various studies. Comparing these bright LAEs and the faint dropouts, we find anti-correlations between the UV-nebular line EW_0 and UV-continuum luminosity, which are similar to those found at z~2-3.

description: In this letter, a matrix method is employed to study the scalar quasinormal modes of Kerr as well as Kerr-Sen black holes. Discretization is applied to transfer the scalar perturbation equation into a matrix form eigenvalue problem, where the resulting radial and angular equations are derived by the method of separation of variables. The eigenvalues, quasinormal frequencies $ω$ and angular quantum numbers $λ$, are then obtained by numerically solving the resultant homogeneous matrix equation. This work shows that the present approach is an accurate as well as efficient method for investigating quasinormal modes.

description: We develop an asymptotical control theory for one of the simplest distributed oscillating systems, namely, for a closed string under a bounded load applied to a single distinguished point. We find exact classes of string states that admit complete damping and an asymptotically exact value of the required time. By using approximate reachable sets instead of exact ones, we design a dry-friction like feedback control, which turns out to be asymptotically optimal. We prove the existence of motion under the control using a rather explicit solution of a nonlinear wave equation. Remarkably, the solution is determined via purely algebraic operations. The main result is a proof of asymptotic optimality of the control thus constructed.

description: From the Iranian revolution in 1979 to the London underground suicide bombings on the 7th of July 2005, the image of Islam as a militant anti-Western faith featured dominantly in the global mass media. This thesis examines the claim that the Western media representation of Islam, the second largest religion in the world with over one billion followers, is predominantly negative and demonizing. Current debates attribute this demonizing and reductive representation to the historically polarised relationship between Islam the West. Central to this argument is that the Western media in general, and the press in particular, tend to report an incomplete fragment of a rather complex situation, and represent the acts of Islamic militant movements and groups as an archetype of Islam. Few researchers used qualitative means to address the issue of representation of Islam in the media. This thesis investigates the representation of Islam in three British dailies, selected for their political different standpoints, and asks to what extent this representation is influenced by the historically conditioned Orientalist discourses that seek to construct and maintain hegemonic perceptions of Islam. The thesis argues that Islam and Muslim societies are a highly diverse reality, which is not confined only to extremism, confrontation, violence, terrorism and antagonism towards everything Western and challenges the monolithic approach that reinforces blanket generalisations, stereotypes and views of Islam/Muslims, based on the common perception of Islam as rooted in the West's self-definition as the negative `Other'. Using discourse analysis, the research seeks to deconstruct the selected news reports in order to highlight what was actually covered, and how news stories were framed and knowledge of Islam was generally produced through discourse(s) and point out that such representations are informed by specific relations of power.
Factorizable $R$-Matrices for Small Quantum Groups

description: Representations of small quantum groups $u_q({\mathfrak{g}})$ at a root of unity and their extensions provide interesting tensor categories, that appear in different areas of algebra and mathematical physics. There is an ansatz by Lusztig to endow these categories with the structure of a braided tensor category. In this article we determine all solutions to this ansatz that lead to a non-degenerate braiding. Particularly interesting are cases where the order of $q$ has common divisors with root lengths. In this way we produce familiar and unfamiliar series of (non-semisimple) modular tensor categories. In the degenerate cases we determine the group of so-called transparent objects for further use.

Improving effectiveness of mobile learning technology for use in higher education: A comparative study of the UK and Jordan
Creators: name: Jawarneh, Ali Yousef
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Higher education

description: This research is aimed at assessing the capabilities and limitations of mobile learning technology
 and its impact on learning in Jordanian higher education. The data was collected through three
 sets of activities, namely a quiz, a questionnaire survey regarding mobile learning content in
 Jordan and two sets of focus groups that were conducted at Aston University and the University
 of Jordan. The mobile learning content was modified, keeping in view the technology limitations
 of both the countries, enabling identification of a broader aim of determining appropriate
 measures for mobile learning within limited technology environments. The quantifiable data was
 examined by using a Wilcoxon signed rank test and Cronbachâ€™s alpha and the qualitative data
 was examined through thematic analysis.
 The results show that the execution of learning through mobile devices in the University of
 Jordan lacks the availability of advanced IT infrastructure. However, the examination of the
 focus group data shows that the participating students from Aston University and the University
 of Jordan experience the same concerns regarding mobile learning. For example, the undersized
 display of handheld devices and restrictive battery lifespan were mentioned by the participants at
 both universities as the restricting factors that limit the use of learning through mobiles.
 The research also found some contradictions between the extant literature and the research data
 obtained through three learning activities on the mobile learning content. For instance, the
 participants mentioned the battery life of mobile gadgets as a limitation but the literature
 revealed that with technological advancements in the form of availability of power bank devices,
 thus the issue of limited battery life is insignificant. The theoretical contribution of this research
 is the application of two mobile learning theories, TPACK theory and Connectivism theory for
 the creation of mobile learning content for this research. This research helps to examine the
 technology gap present in Jordan in contrast to the UK and identify the challenges and
 limitations of using communication devices for m-learning in Jordan; the technology gap
 between Aston University and the University of Jordan has been highlighted.
Approaches to council housing management: a study of 'best value' implementation in two London boroughs
Creators: name: Hunt, Robert
Publisher: name: University of Westminster
Year: 2005

description: This thesis comprises research into the implementation of Best Value in council housing. Best value is a nationally determined framework specifying the process which local authorities must use to review and improve the full range of their activities with regard to performance, quality, accountability and cost. The aim of the research is to evaluate the extent to which local variables impact upon policy outcomes: the implementation of policy. The central research question is: 'In what ways were local relationships redefined following the introduction of Best Value?'. The basis for the study is a view that local determination of policy by an influential group is enhanced through Best Value implementation, in contradiction with its intention. The theoretical footing of this work is derived from a notion that managers 'bureau shape' when conditions allow, rather than 'empire build' as competing theories maintain (Dunleavy 1991). It is hypothesised that Best Value was in part devised to check 'empire building' tendencies and this is a flawed assumption that could lead to unintended policy outcomes. This notion is tested through field research examining the views of councillors, managers, front line workers and residents from two London boroughs, Westminster and Newham. The conclusions drawn relay a set of determinants, each related: the nature of the policy in question; local actors' 'alignment' to that policy and the influence they have; and the extent and nature of change required to meet perceived policy directives. The essence of local policy determination relates to political context and the mediation of relationships between actors. The final point made is that future research could fruitfully examine process as the measure of policy successes and failures, rather than policy outputs.

Strong Functional Representation Lemma and Applications to Coding Theorems
Creators: name: Li, Cheuk Ting

Publisher: name: arXiv
Year: 2017
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: This paper shows that for any random variables $X$ and $Y$, it is possible to represent $Y$ as a function of $(X,Z)$ such that $Z$ is independent of $X$ and $I(X;Z|Y)\le\log(I(X;Y)+1)+4$ bits. We use this strong functional representation lemma (SFRL) to establish a bound on the rate needed for one-shot exact channel simulation for general (discrete or continuous) random variables, strengthening the results by Harsha et al. and Braverman and Garg, and to establish new and simple achievability results for one-shot variable-length lossy source coding, multiple description coding and Gray-Wyner system. We also show that the SFRL can be used to reduce the channel with state noncausally known at the encoder to a point-to-point channel, which provides a simple achievability proof of the Gelfand-Pinsker theorem.
