description: Waveguides have been successfully used to generate magnetic resonance images at 7 T with whole-body systems. The bore limits the magnetic resonance signal transmitted because its specific cut-off frequency is greater than the majority of resonant frequencies. This restriction can be overcome by using a parallel-plate waveguide whose cut-off frequency is zero for the transversal electric modes and it can propagate any frequency. To investigate the potential benefits for whole-body imaging at 3 T, we compare numerical simulations at 1.5 T, 3 T, 7 T, and 9 T via the propagation of the parallel-plate waveguide principal mode filled with a cylindrical phantom and two surface coils. B1 mapping was computed to investigate the feasibility of this approach at 3T. The point spread function method was used to measure the imager performance for the traveling-wave magnetic resonance imaging experiment. Human leg images were acquired to experimentally validate this approach. The principal mode shows very little field magnitude variations along the propagation direction at 3 T when compared to other higher resonant frequencies. The B1 mapping showed that it is possible to conduct experiments using the traveling-wave approach at 128 MHz. The point spread function results showed a good scanner performance for these type of experiments. Leg images were obtained with the whole-body birdcage coil and the waveguide with two circular coils for comparison purposes. The simulated and in vivo traveling-wave results correspond very well for both magnetic field and specific absorption rate. A pretty similar performance was observed for the traveling-wave approach and the conventional one. We have demonstrated the feasibility of traveling-wave magnetic resonance imaging at 3T for whole-body magnetic resonance systems, using a parallel-plate waveguide with standard pulse sequences and only one coil array.

description: In this paper, we analyze how to calculate the matrix transposition in continuous flow by using a memory or group of memories. The proposed approach studies this problem for specific conditions such as square and non-square matrices, use of limited access memories and use of several memories in parallel. Contrary to previous approaches, which are based on specific cases or examples, the proposed approach derives the fundamental theory involved in the problem of matrix transposition in a continuous flow. This allows for obtaining the exact equations for the read and write addresses of the memories and other control signals in the circuits. Furthermore, the cases that involve non-square matrices, which have not been studied in detail in the literature, are analyzed in depth in this paper. Experimental results show that the proposed approach is capable of transposing matrices of 8192 times 8192 32-bit data received in series at a rate of 200 mega samples per second, which doubles the throughput of previous approaches. ¬© 2004-2012 IEEE.

description: The magnetic excitation spectrums of charge stripe ordered La(2-x)Sr(x)NiO(4) x = 0.45 and x = 0.4 were studied by inelastic neutron scattering. We found the magnetic excitation spectrum of x = 0.45 from the ordered Ni^2+ S = 1 spins to match that of checkerboard charge ordered La(1.5)Sr(0.5)NiO(4). The distinctive asymmetry in the magnetic excitations above 40 meV was observed for both doping levels, but an additional ferromagnetic mode was observed in x = 0.45 and not in the x = 0.4. We discuss the origin of crossover in the excitation spectrum between x = 0.45 and x = 0.4 with respect to discommensurations in the charge stripe structure.

description: Logic programs under the stable model semantics, or answer-set programs, provide an expressive rule-based knowledge representation framework, featuring a formal, declarative and well-understood semantics. However, handling the evolution of rule bases is still a largely open problem. The AGM framework for belief change was shown to give inappropriate results when directly applied to logic programs under a non-monotonic semantics such as the stable models. The approaches to address this issue, developed so far, proposed update semantics based on manipulating the syntactic structure of programs and rules. More recently, AGM revision has been successfully applied to a significantly more expressive semantic characterisation of logic programs based on SE-models. This is an important step, as it changes the focus from the evolution of a syntactic representation of a rule base to the evolution of its semantic content. In this paper, we borrow results from the area of belief update to tackle the problem of updating (instead of revising) answer-set programs. We prove a representation theorem which makes it possible to constructively define any operator satisfying a set of postulates derived from Katsuno and Mendelzon's postulates for belief update. We define a specific operator based on this theorem, examine its computational complexity and compare the behaviour of this operator with syntactic rule update semantics from the literature. Perhaps surprisingly, we uncover a serious drawback of all rule update operators based on Katsuno and Mendelzon's approach to update and on SE-models.

Creators: name: Kiefel, Max
Publisher: name: London School of Economics and Political Science (LSE)
Year: 2022

description: Why are left parties in a state of crisis? Existing explanations tend to explain this outcome through exogenous processes, like de-industrialisation and the expansion of education, that have re-aligned the structure of party competition by reducing demand for left parties. By implication, there is little that left parties can do in response. However, I argue that left parties’ historical growth and survival was contingent on their capacity to adapt to exogenous pressures. I synthesise articulation theory with an organisational approach to party politics, which provides me with the conceptual tools to identify a process whereby a party responds to a critical juncture that disarticulates its social bloc through ideological re-orientation. This is contingent on the emergence of new types of actors within a party’s power structure who provide new interpretations on the party’s social relations. This new internal dynamic must be institutionalised and legitimised across the party organisation. This process updates the party’s orientation and provides it with the relevant ideas to articulate a new social bloc. However, I argue that the way in which left parties cartelised in the 1990s creates in-built constraints that are centred on the hegemonic dominance of electoral professional elites, which prevents this process of orientation from unfolding. I apply this argument to the case of the British Labour party in the period 2010-2020. This is an important case as Labour was one of the few parties to attempt an avowed shift from a cartel organisational structure and Third Way orientation. I show that the cartel power structure enabled pre-existing elites to stymie both Ed Miliband’s reformist attempt at re-orientation, and Jeremy Corbyn’s more radical shift. The thesis is significant as it challenges behaviouralist accounts of left party decline. My findings have implications for our understanding of the place of mainstream parties in contemporary party systems and opens up questions over whether de-cartelisation is possible.

description: Based on the recently developed picture of an electronic ideal relativistic fluid at the Dirac point, we present an analytical model for the conductivity in graphene that is able to describe the linear dependence on the carrier density and the existence of a minimum conductivity. The model treats impurities as submerged rigid obstacles, forming a disordered medium through which graphene electrons flow, in close analogy with classical fluid dynamics. To describe the minimum conductivity, we take into account the additional carrier density induced by the impurities in the sample. The model, which predicts the conductivity as a function of the impurity fraction of the sample, is supported by extensive simulations for different values of ${\cal E}$, the dimensionless strength of the electric field, and provides excellent agreement with experimental data.

Top Polarization in Stop Production at the LHC

description: We survey the expected polarization of the top produced in the decay of a scalar top quark, $\tilde t \rightarrow {\tilde t}χ_i^0, i =1-2$. The phenomenology is quite interesting, since the expected polarization depends both on the mixing in the stop and neutralino sectors and on the mass differences between the stop and the neutralino. We find that a mixed stop behaves almost like a right-handed stop due to the larger hypercharge that enters the stop/top/gaugino coupling and that these polarisation effects disappear, when $m_{\tilde t_1} \approx m_t+m_{\tildeχ^0_i}$. After a discussion on the expected top polarization from the decay of a scalar top quark, we focus on the interplay of polarization and kinematics at the LHC. We discuss different probes of the top polarization in terms of lab-frame observables. We find that these observables faithfully reflect the polarization of the parent top-quark, but also have a non-trivial dependence on the kinematics of the stop production and decay process. In addition, we illustrate the effect of top polarization on the energy and transverse momentum of the decay lepton in the laboratory frame. Our results show that both spectra are softened substantially in case of a negatively polarized top, particularly for a large mass difference between the stop and the neutralino. Thus, the search strategies, and the conclusions that can be drawn from them, depends not just on the mass difference $m_{\tilde t} - m_{\tildeχ_{i}^{0}}$ due to the usual kinematic effects but also on the effects of top polarization on the decay kinematics the extent of which depends in turn on the said mass difference.

description: In many polarimetry applications, including observations in the X-ray band, the measurement of a polarization signal can be reduced to the detection and quantification of a deviation from uniformity of a distribution of measured angles. We explore the statistics of such polarization measurements using Monte Carlo simulations and chi-squared fitting methods. We compare our results to those derived using the traditional probability density used to characterize polarization measurements and quantify how they deviate as the intrinsic modulation amplitude grows. We derive relations for the number of counts required to reach a given detection level (parameterized by beta, the "number of sigma's" of the measurement) appropriate for measuring the modulation amplitude by itself (single interesting parameter case) or jointly with the position angle (two interesting parameters case). We show that for the former case when the intrinsic amplitude is equal to the well known minimum detectable polarization (MDP) it is, on average, detected at the 3-sigma level. For the latter case, when one requires a joint measurement at the same confidence level, then more counts are needed than that required to achieve the MDP level. This additional factor is amplitude-dependent, but is approximately 2.2 for intrinsic amplitudes less than about 20%. It decreases slowly with amplitude and is 1.8 when the amplitude is 50%. We find that the position angle uncertainty at 1-sigma confidence is well described by the relation 28.5 (deg) / beta.

With computational experiments and theoretical arguments we are able to derive several partial differential equation limits identified (or nearly identified) in previous studies and to clarify the correct choice of surface tension appearing in the PDE and the correct scaling regime giving rise to each PDE. We also provide preliminary computational investigations of a number of interesting qualitative features of the large scale behavior of the models.

title: The practice of ordained ministry within the contemporary Church of Scotland: Problems of identity, role and function
Creators: name: Macaskill, Donald
Publisher: name: University of Glasgow
Year: 1998
Subjects: subject: Church of Scotland, clergy, religion.

description: This work arises from a premise that the practice of ordained ministry within the Church of Scotland is in a state of 'crisis' and it suggests that this analysis is appropriate. The nature of this crisis is discussed together with institutional reactions thereto. Following a presentation of the concepts of role, identity and the self, consideration is given to the role of the parish minister in Scotland up to the contemporary period. Consideration is given to the changing role of the minister in contemporary Scotland, the issue of professionalisation and the affects of role conflict and uncertainty on the conditions of stress and burnout in ministry. Thereafter analysis of the main aspects of ministerial practice is achieved through means of a postal questionnaire and structured interview technique. Vocational issues of initial vocation, training, priority, worship and theology are examined and discussed, followed by more relational aspects of practice, including, pastoral care, family and spouse relationships, women in ministry, congregation and collegial relationship and most particularly the minister's self- understanding and self care. In each of these areas it is suggested that the contemporary practice of ministry is evidencing disease and distress and that such a practice vitiates a resolution of the perceived 'crisis' of identity and role. Nevertheless it remains clear that for the majority of parish ministers the functions of worship leadership, particularly preaching and pastoral care remain dominant within their self-conception of their role and identity. A relational, social trinitarian theology of ministry is advanced together with the model of minister as human friend. Both emphasise and concentrate on the relational dynamics of ministry. It is argued that there needs to be an examination of the relationship between function and being in ministry, together with a re-conceptualisation of the nature of ordination, the role of the sacraments in ordained ministry and the relationship between the ordained and the whole people of God. Recommendations are offered for both institutional and theological change to encourage the development of a ministerial practice and theology which concentrates and affirms the relational dimension of parish ministry.

description: Die verstärkte Einspeisung von Strom aus fluktuierender Erneuerbarer Energieerzeugung stellt unser Energiesystem vor große Herausforderungen. Gebäuden kommt vor diesem Hintergrund eine wichtige Rolle als flexible Verbraucher und Erzeuger zu. Neben dem Nutzerkomfort und der Energieeffizienz von Gebäuden wird zukünftig auch ihr Einfluss auf das Stromnetz zur Optimierungsgröße. In Verbindung mit einer Betonkerntemperierung (BKT) birgt die Gebäudemasse ein erhebliches Lastmanagement-Potenzial. Die in dieser Arbeit entwickelte netzgeführte Taktbetriebsstrategie soll helfen, dieses Potenzial im praktischen Gebäudebetrieb wirkungsvoll und effizient zu nutzen. Grundlage für die Untersuchungen sind die Planungsdaten eines in 2020 fertig- gestellten Nichtwohngebäudes. Anhand dieser wurde in der Simulationsumgebung TRNSYS ein komplexes Gebäude- und Anlagenmodell zur Versorgung einer Bürozone aufgebaut. Im Modell erfolgt die Grundbeheizung sowie die Kühlung der Zone im Sommer über eine mittig in der Betondecke angeordnete BKT. Die Wärme- und Kältebereitstellung für die BKT erfolgt über eine erdreichgekoppelte reversible Wärmepumpe. Die Beladung der BKT in der Referenzvariante erfolgt im Dauerbetrieb über außentemperaturabhängige Heiz-/Kühlkurven nach dem Unknown-But-Bounded-Verfahren (UBB). Darauf aufbauend wird eine netzgeführte Taktstrategie auf Basis des UBB-Taktverfahrens entwickelt. Ziel der Netzführung auf Grundlage eines entwickelten Netzsignals ist die Verschiebung der Beladungszeiten der Betondecke in Zeiten, die im Hinblick auf das elektrische Energiesystem als günstig zu bewerten sind. Die in Frage kommenden Netzreferenzgrößen werden auf Basis von Netzdaten der Jahre 2017 bis 2020 bewertet. Es werden die Auswirkungen der Betriebsstrategie im Hinblick auf thermischen Raumkomfort, Energieeffizienz und -verbrauch sowie den Netzeinfluss der Wärme- und Kälteversorgung der Bürozone untersucht. Im Ergebnis zeigt sich, dass die „Netzdienlichkeit“ des Gesamtsystems durch Anwendung der Netzführung der BKT signifikant erhöht werden kann. Die definierten Komfortanforderungen werden eingehalten, im Hinblick auf Energieeffizienz und -verbrauch sind nur leichte Einbußen zu beobachten.

description: We investigate the asymptotic symmetry group of the free SU(N )-Yang-Mills theory using the Hamiltonian formalism. We closely follow the strategy of Henneaux and Troessaert who successfully applied the Hamiltonian formalism to the case of gravity and electrodynamics, thereby deriving the respective asymptotic symmetry groups of these theories from clear-cut first principles. These principles include the minimal assumptions that are necessary to ensure the existence of Hamiltonian structures (phase space, symplectic form, differentiable Hamiltonian) and, in case of Poincaré invariant theories, a canonical action of the Poincaré group. In the first part of the paper we show how these requirements can be met in the non-abelian SU(N )-Yang-Mills case by imposing suitable fall-off and parity conditions on the fields. We observe that these conditions admit neither non-trivial asymptotic symmetries nor non-zero global charges. In the second part of the paper we discuss possible gradual relaxations of these conditions by following the same strategy that Henneaux and Troessaert had employed to remedy a similar situation in the electromagnetic case. Contrary to our expectation and the findings of Henneaux and Troessaert for the abelian case, there seems to be no relaxation that meets the requirements of a Hamiltonian formalism and allows for non-trivial asymptotic symmetries and charges. Non-trivial asymptotic symmetries and charges are only possible if either the Poincaré group fails to act canonically or if the formal expression for the symplectic form diverges, i.e. the form does not exist. This seems to hint at a kind of colour-confinement built into the classical Hamiltonian formulation of non-abelian gauge theories.

description: Probiotics from non-traditional sources (nondairy and non-intestinal) have better potential of surviving in the nondairy based foods that are required to overcome the limitations of dairy-based (traditional) probiotic products. This study aimed to evaluate the probiotic potential of lactic acid bacteria isolated from traditional and non-traditional sources in vitro. Thirteen isolates were evaluated for their probiotic properties, including survival under harsh conditions, antimicrobial activity, cell surface hydrophobicity, auto-aggregation and safety. Nondairy isolates (Limosilactobacillus fermentum AIFe1, Pediococcus pentosaceus BRDb27, Lactiplantibacillus plantarum ACFe58 and Lactiplantibacillus plantarum KCFe63) and dairy isolate (Limosilactobacillus fermentum NCCu21) exhibited excellent beneficial properties. Isolate KCFe63 showed good antioxidant potential (66.91% ± 0.02) and cholesterol assimilation (81.48% ± 0.07), while isolate BRDb27 displayed high adhesion ability (77.98% ± 0.71) toward HT-29 cells whereas isolate ACFe58 revealed antiproliferative effects against MCF-7 cells (40.55% ± 0.15 cell survival). These findings suggest that the non-traditional isolates are promising probiotic candidates and can be further explored for commercialization.

description: Typically, disassembly forces are unknown due to high forces or high temperatures during product operation, where assembly connections solidify. For the regulation of disassembly forces a controller is developed. The controller is formed for two steps: The first step is a PID controller that produces a force, which overcomes a solidifying force slightly. The second step is a vibration controller with a FM modulation to regulate the frequency of impacts. Vibrations are useful for decreasing the force amplitude for caring the joined components. Finally, the control is validated with disturbances in a simulation. © 2019 The Author(s).

description: The state of asymptotic silence, characterized by causal disconnection of the space points, emerges from various approaches aiming to describe gravitational phenomena in the limit of large curvatures. In particular, such behavior was anticipated by Belinsky, Khalatnikov and Lifshitz (BKL) in their famous conjecture put forward in the early seventies of the last century. While the BKL conjecture is based on purely classical considerations, one can expect that asymptotic silence should have its quantum counterpart at the level of a more fundamental theory of quantum gravity, which is the relevant description of gravitational phenomena in the limit of large energy densities. Here, we summarize some recent results which give support to such a possibility. More precisely, we discuss occurrence of the asymptotic silence due to polymerization of space at the Planck scale, in the framework of loop quantum cosmology. In the discussed model, the state of asymptotic silence is realized at the energy density $ρ= ρ_c/2$, where $ρ_c$ is the maximal allowed energy density, being of the order of the Planck energy density. At energy densities $ρ> ρ_c/2$, the universe becomes 4D Euclidean space without causal structure. Therefore, the asymptotic silence appears to be an intermediate state of space between the Lorentzian and Euclidean phases.

description: Fermented cassava is obtained through fermentation process where the main role is played by various lactic acid bacteria (LAB), while the by-products (effluents) are discarded. The objective of this study was to isolate, identify and analyze potential probiotics in fermented cassava by-products/effluents using molecular techniques. We quantified the LAB’s metabolites and tested their antimicrobial properties. We isolated 13 LAB strains which are all Gram-positive, and catalase, oxidase, indole and coagulase negative. Only 6 out of 13 selected isolates survived the low pH of 1.5 and 0.3% bile salt. These 6 isolates showed different levels of antimicrobial activity against the tested pathogens with zones of inhibition ranging from 5.10 mm to 22.80 mm. The isolated LAB were identified as Lactiplantibacillus plantarum and Limosilactobacillus fermentum. The results indicated that the selected LAB strains have potential as probiotics due to their ability to survive in acidic and bile-rich environments as well as their antimicrobial properties.

Polarized extended Ly-alpha emission from a z=2.3 radio galaxy

description: We present spatially resolved spectropolarimetic measurements of the 100-kpc scale gaseous environment of the z=2.34 radio galaxy TXS 0211-122. The polarization level of the narrow Ly-alpha emission is low centrally (P<5 %), but rises to P=16.4+/-4.6 % in the Eastern part of the nebula, indicating that the nebula is at least partly powered by the scattering of Ly-alpha photons by HI. Not only is this the first detection of polarized Ly-alpha around a radio-loud active galaxy, it is also the second detection to date for any kind of Ly-alpha nebula. We also detect a pair of diametrically opposed UV continuum sources along the slit, at the outer edges of the Ly-alpha nebula, which we suggest may be the limb of a dusty shell, related to the large-scale HI absorbers often associated with high-z radio galaxies.

description: Holm and Jorgensen have shown the existence of a cluster structure on a certain category $D$ that shares many properties with finite type $A$ cluster categories and that can be fruitfully considered as an infinite analogue of these. In this work we determine fully the combinatorics of this cluster structure and show that these are the cluster combinatorics of cluster algebras of infinite rank. That is, the clusters of these algebras contain infinitely many variables, although one is only permitted to make finite sequences of mutations. The cluster combinatorics of the category $D$ are described by triangulations of an $\infty$-gon and we see that these have a natural correspondence with the behaviour of Plucker coordinates in the coordinate ring of a doubly-infinite Grassmannian, and hence the latter is where a concrete realization of these cluster algebra structures may be found. We also give the quantum analogue of these results, generalising work of the first author and Launois. An appendix by Michael Groechenig provides a construction of the coordinate ring of interest here, generalizing the well-known scheme-theoretic constructions for Grassmannians of finite-dimensional vector spaces.

description: We report on the magnetic and structural properties of La2Ni(Ni1/3Sb2/3)O6 in polycrystal, single crystal and thin film samples. We found that this material is a ferrimagnet (Tc ~ 100 K) which possesses a very distinctive and uncommon feature in its virgin curve of the hysteresis loops. We observe that bellow 20 K it lies outside the hysteresis cycle, and this feature was found to be an indication of a microscopically irreversible process possibly involving the interplay of competing antiferromagnetic interactions that hinder the initial movement of domain walls. This initial magnetic state is overcome by applying a temperature dependent characteristic field. Above this field, an isothermal magnetic demagnetization of the samples yield a ground state different from the initial thermally demagnetized one.
