description: We study the plane-symmetric collision of two gravitational waves and describe the global spacetime geometry generated by this collision. To this end, we formulate the characteristic initial value problem for the Einstein equations, when Goursat data describing the incoming waves are prescribed on two null hypersurfaces. We then construct a global solution representing a cyclic spacetime based on junction conditions associated with a prescribed singularity scattering map (a notion recently introduced by the authors). From a mathematical analysis standpoint, this amounts to a detailed analysis of the Goursat and Fuchsian initial value problems associated with singular hyperbolic equations, when junction conditions at interfaces are prescribed. In our construction, we introduce a partition into monotonicity diamonds (that is, suitable spacetime domains) and we construct the solution by concatenating domains across interfaces of timelike, null, or spacelike type.

description: Die 1990 abgehaltenen Mehrparteienwahlen waren nicht nur der Auftakt für die kroatische Staatsgründung, sondern auch für einen Krieg, der die Sicherung eines patriarchal-autoritären Regimes unter der Führung der Sammelpartei HDZ (Kroatische demokratische Gemeinschaft) und des Staatsgründers Franjo Tuđman möglich machte. Die auf nationale Verteidigung ausgerichtete Staatsgründung schuf einerseits ein schwieriges Fundament für eine weitreichende Demokratisierung des Landes. Andererseits beförderte die Konflikt- und Gewaltsituation ein bereits zu jugoslawischen Zeiten existentes kritisches zivilgesellschaftliches Engagement, das auch von zahlreichen feministischen Gruppen getragen wurde. Gerade sie hatten während der Kriege der 1990er Jahre immer wieder ihre Stimme gegen sexuelle und militärische Gewalt sowie gegen autoritäre Strukturen erhoben. Darin enthalten waren Forderungen nach Anerkennung von Differenz, Gleichberechtigung und politischer Partizipation, ebenso wie nach rationaler Selbstreflexion und Kritikfähigkeit von Staat und Gesellschaft.
Die postsozialistische Transformation des jüngsten EU-Staates Kroatien zeigt sich in der vorliegenden Untersuchung als Teil eines Prozesses des konfliktbehafteten Umbaus von Staatlichkeit, der seit Ende der Habsburger Monarchie andauert. Während in der jugoslawischen und kroatischen Geschichtsschreibung entweder die nationale Differenz oder soziale Ausschlussmechanismen als Motor der Transformation des Staates und damit als Erklärungsmodell dominieren, wird hier der analytische Blick auf das Verhältnis von Staat und Geschlechterdifferenz gelenkt. Im Zentrum der Untersuchung steht die staatskritische Dimension der jugoslawischen feministischen Wissensproduktion, deren Traditionen die heutige feministische Kritik in Kroatien und seinen Nachbarstaaten prägen, aber selten in einen staatstheoretischen Kontext gestellt werden.
Ziel der Dissertation ist daher, die Geschichte emanzipativer und feministischer Kritik in Jugoslawien unter dem Aspekt der Staatskritik neu zu bewerten und sie im kroatischen nationalstaatlichen Kontext in einer Genealogie feministischen Wissens zu verorten. Auf diese Weise wird die postjugoslawische feministische Auseinandersetzung mit dem Nationalstaat und den Zerfallskriegen der 1990er Jahre einerseits einer kritischen Würdigung unterzogen. Andererseits wird sie in einem abschließenden Kapitel in einem erweiterten feministischen Theoriekontext betrachtet, der die Analyse von Staatlichkeit anhand von Narrativen und von Männlichkeitskonstruktionen erprobt. Öffentlichkeit dient als zentraler Begriff und Reibungspunkt der Beschreibung der politischen Dimension feministischen Wissens in Jugoslawien und Kroatien. Herausgearbeitet wird, dass die Kritik und Erweiterung von Öffentlichkeit das politische Feld darstellt, welches für feministisches Handeln und Intervenieren in gesellschaftliche und staatliche Machtbeziehungen in Jugoslawien und Kroatien zentral ist.

description: Historic American Engineering Record (HAER) No. AZ-17 presents a written historical summary and relevant historical documentation about the construction and use of Grand Canal, which delivers water to users on the north side of the Salt River for agricultural, industrial, and municipal uses. Historic American Engineering Record (HAER) No. AZ-30 provides similar documentation about the construction and operation of the Crosscut Hydroelectric Plant, which sits at the head of Grand Canal and relies on canal water flow to generate power. The reports contain narrative descriptions, photographs, drawings, and maps. Although the Salt River Valley and the Phoenix Metropolitan area lie within a semi-arid, desert-like region of central Arizona, modern farming and urban development were made possible by the damming of the Salt and Verde rivers by the U.S. Bureau of Reclamation during the early 1900s. While the Salt River Valley was developing as a result of successful efforts to control the river's flow for irrigation, the young cities of the Valley were experiencing the social and technological changes of the late 19th century. One of these was the coming of the electrical age. The first widespread use of electricity in the Valley was to increase the amount of the irrigated acreage by pumping groundwater. Due to a lack of readily accessible fuel, valley citizens soon realized the importance of hydroelectric generation, and the Salt River Project (SRP) realized the importance of developing it. The Crosscut Hydro plant was the largest and most important low-head hydro plant built on the SRP canal system. It was also the center of the SRP electrical distribution system for many years. The hydro plant was built at the head of the Grand Canal (see HAER No. AZ-17) and has always been operationally dependent on the flow of water through the Grand Canal to generate power.

description: Navigation, bio-tracking devices and gravity gradiometry are amongst the diverse range of applications requiring ultrasensitive measurements of acceleration. We describe an accelerometer that exploits the dispersive and dissipative coupling of the motion of an optical whispering gallery mode (WGM) resonator to a waveguide. A silica microsphere-cantilever is used as both the optical cavity and inertial test-mass. Deflections of the cantilever in response to acceleration alter the evanescent coupling between the microsphere and the waveguide, in turn causing a measurable frequency shift and broadening of the WGM resonance. The theory of this optomechanical response is outlined. By extracting the dispersive and dissipative optomechanical rates from data we find good agreement between our model and sensor response. A noise density of 4.5 $μ$g Hz$^{-1/2}$ with a bias instability of 31.8 $μ$g (g=9.81 ms$^{-2}$) is measured, limited by classical noise larger than the test-mass thermal motion. Closed-loop feedback is demonstrated to reduce the bias instability and long term drift. Currently this sensor outperforms both commercial accelerometers used for navigation and those in ballistocardiology for monitoring blood flowing into the heart. Further optimization would enable short-range gravitational force detection with operation beyond the lab for terrestrial or space gradiometry.

description: Reproducing kernel Hilbert spaces (RKHSs) play an important role in many statistics and machine learning applications ranging from support vector machines to Gaussian processes and kernel embeddings of distributions. Operators acting on such spaces are, for instance, required to embed conditional probability distributions in order to implement the kernel Bayes rule and build sequential data models. It was recently shown that transfer operators such as the Perron-Frobenius or Koopman operator can also be approximated in a similar fashion using covariance and cross-covariance operators and that eigenfunctions of these operators can be obtained by solving associated matrix eigenvalue problems. The goal of this paper is to provide a solid functional analytic foundation for the eigenvalue decomposition of RKHS operators and to extend the approach to the singular value decomposition. The results are illustrated with simple guiding examples.

description: The problem of calculating the Casimir force on two conducting planes by means of the stress tensor is examined. The evaluation of this quantity is carried out using an explicit regularization procedure which has its origin in the underlying (2+1) dimensional Poincaré invariance of the system. The force between the planes is found to depend on the ratio of two independent cutoff parameters, thereby rendering any prediction for the Casimir effect an explicit function of the particular calculational scheme employed. Similar results are shown to obtain in the case of the conducting sphere.

description: Salt River Project (SRP) recently assumed responsibility for the construction of a 2 3/4 mile segment of the Coronado-Silverking APS-SRP Common Corridor Transmission Line. Due to this change in construction plans, Bettina Rosenberg, SRP Archeological Administrator, contacted the Museum of Northern Arizona (MNA) on November 30, 1977, and requested a resurvey of the tower locations on this portion of the transmission line. The line was originally surveyed by Arizona State Museum (ASM), but the resurvey was deemed necessary because of the relocation of some towers and the archeological sensitivity of the area. ASM conducted three surveys in the Common Corridor area. Two of the surveys covered the entire corridor, while the third survey investigated five tower relocations and associated access roads. These access roads are now in place along the line. Two sites were recorded by ASM within the area recently surveyed by MNA. Archeological sites along the 2 3/4 mi. segment of the Common Corridor are limited to these two previously recorded sites and one site recorded during the MNA survey. The survey was conducted and this report prepared under the stipulations and guidelines of the Cultural Resources Plan developed by the National Forest Service (NFS) for the Coronado Project.

description: Random spanning trees of a graph $G$ are governed by a corresponding probability mass distribution (or "law"), $μ$, defined on the set of all spanning trees of $G$. This paper addresses the problem of choosing $μ$ in order to utilize the edges as "fairly" as possible. This turns out to be equivalent to minimizing, with respect to $μ$, the expected overlap of two independent random spanning trees sampled with law $μ$. In the process, we introduce the notion of homogeneous graphs. These are graphs for which it is possible to choose a random spanning tree so that all edges have equal usage probability. The main result is a deflation process that identifies a hierarchical structure of arbitrary graphs in terms of homogeneous subgraphs, which we call homogeneous cores. A key tool in the analysis is the spanning tree modulus, for which there exists an algorithm based on minimum spanning tree algorithms, such as Kruskal's or Prim's.

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: In real-world scenarios, many data processing problems often involve heterogeneous images associated with different imaging modalities. Since these multimodal images originate from the same phenomenon, it is realistic to assume that they share common attributes or characteristics. In this paper, we propose a multi-modal image processing framework based on coupled dictionary learning to capture similarities and disparities between different image modalities. In particular, our framework can capture favorable structure similarities across different image modalities such as edges, corners, and other elementary primitives in a learned sparse transform domain, instead of the original pixel domain, that can be used to improve a number of image processing tasks such as denoising, inpainting, or super-resolution. Practical experiments demonstrate that incorporating multimodal information using our framework brings notable benefits.

Bogomol'nyi solitons in a gauged $O(3)$ sigma model

Year: 1995
Subjects: subject: High Energy Physics - Theory (hep-th)

description: The scale invariance of the $O(3)$ sigma model can be broken by gauging a $U(1)$ subgroup of the $O(3)$ symmetry and including a Maxwell term for the gauge field in the Lagrangian. Adding also a suitable potential one obtains a field theory of Bogomol'nyi type with topological solitons. These solitons are stable against rescaling and carry magnetic flux which can take arbitrary values in some finite interval. The soliton mass is independent of the flux, but the soliton size depends on it. However, dynamically changing the flux requires infinite energy, so the flux, and hence the soliton size, remains constant during time evolution.

Numerical modelling of cardiovascular flows: From in vitro systems to animal models
Creators: name: Van Doormaal, Mark
Publisher: name: Imperial College London
Year: 2010

description: Animal models and in vitro endothelial cell culture devices are used extensively to understand the impacts of hemodynamics (including wall shear stress and mass transfer rates) on endothelial cell physiology and atherogenesis. The purpose of this thesis was to use numerical methods to simulate fluid flow and mass transfer phenomenon in endothelial cell culture devices and the mouse aortic arch in order to better understand endothelial cell physiology and atherogenesis. The design of endothelial cell culture devices that seek to determine the separate roles of abnormal wall shear stress and abnormal mass transfer rates is complicated because areas of "abnormal" mass transfer and "abnormal" wall shear stress tend to co-localize. Therefore, we used numerical methods and design optimization techniques to design two endothelial cell culture devices that are capable of separating areas of low wall shear stress from areas of low wall mass transfer. This resulted in the successful design optimization of one device with a helical geometry and a second device consisting of axial baffles in a tube. In addition to in vitro endothelial cell culture, mouse models of atherosclerosis are often used to investigate endothelial cell physiology. However, the wall shear stress patterns in the aortic arch of the mouse have not been determined using subject-specific aortic root velocity boundary conditions and aortic arch geometry. Using aortic root velocity profiles as measured via MRI and aortic arch geometry measured via CT scan of a corrosion cast of the arch, we determined the subject-specific wall shear stress patterns in the aortic arch of the mouse. We found low levels of wall shear stress in both low- and high- probability areas of atherosclerotic lesion formation. We also found that a mouse-averaged aortic root velocity field can accurately substitute for a subject-specific aortic root velocity field if needed.

description: The associated magnetic moments of the periodic rotational motion of methyl groups in hexamethylbenzene C$_6$(CH$_3$)$_6$ were recently identified to contribute to its overall magnetic susceptibility. Those measurements however, were only performed on hydrogenous polycrystalline samples. We report magnetic susceptibility measurements on single crystalline C$_6$(CH$_3$)$_6$ in the cases where the applied magnetic field is parallel and perpendicular to the molecular basal planes. In the former case, metastable behavior near the onset temperature T$_{C-H}$=118 K is identified while in the latter, no anomalous behavior is observed. Similar anomalies are observed in deuterated hexamethylbenzene C$_6$(CD$_3$)$_6$ (where D is deuterium), however, T$_{C-D}$ occurs 14 K higher at 132 K. In addition, a peak anomaly identified near 42 K is suggested to be due to the onset of coherent quantum tunneling of deuterons. The near cubic ground state is proposed to be the result of a more radical form of the Jahn-Teller effect occurring in a molecular solid where the lattice distorts to remove the orbital degeneracies of the protons to lower its energy. The apparent magnetic anisotropy and isotope effect provide evidence that apart from electrons, not only protons, but also deuterons establish strongly correlated behavior.

Wave-equation based seismic multiple attenuation
Creators: name: Huo, Shoudong
Publisher: name: Imperial College London
Year: 2009

description: Reflection seismology is widely used to map the subsurface geological structure of the Earth. Seismic multiples can contaminate seismic data and are therefore due to be removed. For seismic multiple attenuation, wave-equation based methods are proved to be effective in most cases, which involve two aspects: multiple prediction and multiple subtraction. Targets of both aspects are to develop and apply a fully datadriven algorithm for multiple prediction, and a robust technique for multiple subtraction. Based on many schemes developed by others regarding to the targets, this thesis addresses and tackles the problems of wave-equation based seismic multiple attenuation by several approaches. First, the issue of multiple attenuation in land seismic data is discussed. Multiple Prediction through Inversion (MPTI) method is expanded to be applied in the poststack domain and in the CMP domain to handle the land data with low S/N ratio, irregular geometry and missing traces. A running smooth filter and an adaptive threshold K-NN (nearest neighbours) filter are proposed to help to employ MPTI on land data in the shot domain. Secondly, the result of multiple attenuation depends much upon the effectiveness of the adaptive subtraction. The expanded multi-channel matching (EMCM) filter is proved to be effective. In this thesis, several strategies are discussed to improve the result of EMCM. Among them, to model and subtract the multiples according to their orders is proved to be practical in enhancing the effect of EMCM, and a masking filter is adopted to preserve the energy of primaries. Moreover, an iterative application of EMCM is proposed to give the optimized result. Thirdly, with the limitation of current 3D seismic acquisition geometries, the sampling in the crossline direction is sparse. This seriously affects the application of the 3D multiple attenuation. To tackle the problem, a new approach which applies a trajectory stacking Radon transform along with the energy spectrum is proposed in this thesis. It can replace the time-consuming time-domain sparse inversion with similar effectiveness and much higher efficiency. Parallel computing is discussed in the thesis so as to enhance the efficiency of the strategies. The Message-Passing Interface (MPI) environment is implemented in most of the algorithms mentioned above and greatly improves the efficiency.

description: A graph $G$ is $k$-edge-Hamiltonian if any collection of vertex-disjoint paths with at most $k$ edges altogether belong to a Hamiltonian cycle in $G$. A graph $G$ is $k$-Hamiltonian if for all $S\subseteq V(G)$ with $|S|\le k$, the subgraph induced by $V(G)\setminus S$ has a Hamiltonian cycle. These two concepts are classical extensions for the usual Hamiltonian graphs. In this paper, we present some spectral sufficient conditions for a graph to be $k$-edge-Hamiltonian and $k$-Hamiltonian in terms of the adjacency spectral radius as well as the signless Laplacian spectral radius. Our results could be viewed as slight extensions of the recent theorems proved by Li and Ning [Linear Multilinear Algebra 64 (2016)], Nikiforov [Czechoslovak Math. J. 66 (2016)] and Li, Liu and Peng [Linear Multilinear Algebra 66 (2018)]. Moreover, we shall prove a stability result for graphs being $k$-Hamiltonian, which could be regarded as a complement of two recent results of Füredi, Kostochka and Luo [Discrete Math. 340 (2017)] and [Discrete Math. 342 (2019)].

Options for introducing CO2 capture and capture readiness for coal fired power plants in China
Creators: name: Li, Jia
Publisher: name: Imperial College London
Year: 2010

description: China has been building at least 50GW of new coal‐fired power plants every year since 2004. Previous carbon capture and storage (CCS) research has mainly focussed on technology improvements or stakeholder opinion surveys, without picturing the overall concerns and barriers for deploying such technology in China. This thesis therefore explores the engineering and policy requirements to implement CCS and CO2 Capture Ready (CCR) in Chinese coal‐fired power plants, key enablers for future deployment. A preliminary study of the Chinese gasification industry shows there are early opportunities to capture carbon dioxide from gasification plants. However, as power from conventional pulverised coal (PC) accounts for the majority of electricity generated in China, the most promising emission reduction method for China could be through implementation of CCS technology in large PC plants. An investigation of the current PC plant layouts and operating parameters has been carried out during the course of the study. The results show that, in the absence of CCR designs, a large fraction of such new coal power plants built within the next decade could face ‘carbon lock-in’. A site specific system model using ASPEN Plus to demonstrate the possible changes that could be applied to an existing power plant and a retrofit plant is included in the study. A capture ready power plant site selection method has also been developed, to identify possible sites and to aid understanding of the criteria that should be considered when planning a capture ready plant. A case study of a capture ready power plant in Guangdong province, China shows the benefit of regional planning. Finally, the result of the first stakeholder perception survey on making new coal‐fired plants CCR, conducted in early 2010, are presented and analysed. Evidence for a supportive attitude towards CCR could indicate that this may be a route to early commercial demonstration of CCS in China.

description: The interaction between an electric field and the electric charges in a material is described by electrostatic screening, which in metallic systems is commonly thought to be confined within a distance of the order of the Thomas-Fermi length. The validity of this picture, which holds for surface charges up to $\sim 10^{13}\,\mathrm{cm^{-2}}$, has been recently questioned by several experimental results when dealing with larger surface charges, such as those routinely achieved via the ionic gating technique. Whether these results can be accounted for in a purely electrostatic picture is still debated. In this work, we tackle this issue by calculating the spatial dependence of the charge carrier density in thin slabs of niobium nitride via an ab initio density functional theory approach in the field-effect transistor configuration. We find that perturbations induced by surface charges $\lesssim 10^{14}\,\mathrm{cm^{-2}}$ are mainly screened within the first layer, while those induced by larger surface charges $\sim 10^{15}\,\mathrm{cm^{-2}}$ can penetrate over multiple atomic layers, in reasonable agreement with the available experimental data. Furthermore, we show that a significant contribution to the screening of large fields is associated not only to the accumulation layer of the induced charge carriers at the surface, but also to the polarization of the pre-existing charge density of the undoped system.

Recently, Lin [Linear Algebra Appl. 452 (2014) 1--6] proved a remarkable extension of Oppenheim type inequality for block matrices, which solved a conjecture of Günther and Klotz. There is a requirement that two matrices commute in Lin's result. The motivation of this paper is to obtain another natural and general extension of Oppenheim type inequality for block matrices to get rid of the requirement that two matrices commute.

RDA Interest Group Charter: FAIR Digital Object Fabric
Creators: name: Stotzka, Rainer

name: Quick, Robert
Publisher: name: Zenodo
Year: 2021
Subjects: FAIR Digital Objects, Research Data Alliance

description: The IG Data Fabric was originally founded in 2013 with the scope to harmonize and to orchestrate RDA’s core components for a data infrastructure. Over the years one of the group’s topics shifted more and more to the introduction and specification of FAIR Digital Objects as an overarching concept building up research data infrastructures. The name of the IG Data Fabric is puzzling, confuses potential new RDA members, and promises a steep learning curve to the broad landscape of discussed topics. To address these issues and to focus the objectives, the members of the IG Data Fabric are proposing to change the name of the group to FAIR Digital Object Fabric. This modified IG Charter was discussed in the IG working meeting, September 23rd 2021, and was open for an internal IG Data Fabric review and commenting period from September 27 until October 11 2021.

Canonical forms for boundary conditions of self-adjoint differential operators
Creators: name: Hardy, Yorick
name: Zinsou, Bertin
Publisher: name: arXiv
Year: 2021
Subjects: subject: Classical Analysis and ODEs (math.CA)
subject: FOS: Mathematics
subject: 34B08

description: Canonical forms of boundary conditions are important in the study of the eigenvalues of boundary conditions and their numerical computations. The known canonical forms for self-adjoint differential operators, with eigenvalue parameter dependent boundary conditions, are limited to 4-th order differential operators. We derive canonical forms for self-adjoint 2n-th order differential operators with eigenvalue parameter dependent boundary conditions. We compare the 4-th order canonical forms to the canonical forms derived in this article.

description: We study smooth bundles over surfaces with highly connected almost parallelizable fiber $M$ of even dimension, providing necessary conditions for a manifold to be bordant to the total space of such a bundle and showing that, in most cases, these conditions are also sufficient. Using this, we determine the characteristic numbers realized by total spaces of bundles of this type, deduce divisibility constraints on their signatures and $\hat{A}$-genera, and compute the second integral cohomology of ${\rm BDiff}^+(M)$ up to torsion in terms of generalized Miller--Morita--Mumford classes. We also prove analogous results for topological bundles over surfaces with fiber $M$ and discuss the resulting obstructions to smoothing them.

Reversible Gromov-Monge Sampler for Simulation-Based Inference

description: This paper introduces a new simulation-based inference procedure to model and sample from multi-dimensional probability distributions given access to i.i.d.\ samples, circumventing the usual approaches of explicitly modeling the density function or designing Markov chain Monte Carlo. Motivated by the seminal work on distance and isomorphism between metric measure spaces, we propose a new notion called the Reversible Gromov-Monge (RGM) distance and study how RGM can be used to design new transform samplers to perform simulation-based inference. Our RGM sampler can also estimate optimal alignments between two heterogeneous metric measure spaces $(\cX, μ, c_{\cX})$ and $(\cY, ν, c_{\cY})$ from empirical data sets, with estimated maps that approximately push forward one measure $μ$ to the other $ν$, and vice versa. We study the analytic properties of the RGM distance and derive that under mild conditions, RGM equals the classic Gromov-Wasserstein distance. Curiously, drawing a connection to Brenier's polar factorization, we show that the RGM sampler induces bias towards strong isomorphism with proper choices of $c_{\cX}$ and $c_{\cY}$. Statistical rate of convergence, representation, and optimization questions regarding the induced sampler are studied. Synthetic and real-world examples showcasing the effectiveness of the RGM sampler are also demonstrated.
