description: A direct detection of black hole formation in neutron star mergers would provide invaluable information about matter in neutron star cores and finite temperature effects on the nuclear equation of state. We study black hole formation in neutron star mergers using a set of 190 numerical relativity simulations consisting of long-lived and black-hole-forming remnants. The postmerger gravitational-wave spectrum of a long-lived remnant has greatly reduced power at a frequency $f$ greater than $f_{\rm peak}$, for $f \gtrsim 4\,\rm kHz$, with $f_{\rm peak} \in [2.5, 4]\,\rm kHz$. On the other hand, black-hole-forming remnants exhibit excess power in the same large $f$ region and manifest exponential damping in the time domain characteristic of a quasinormal mode. We demonstrate that the gravitational-wave signal from a collapsed remnant is indeed a quasinormal ringing. We report on the opportunity for direct detections of black hole formation with next-generation gravitational-wave detectors such as Cosmic Explorer and Einstein Telescope and set forth the tantalizing prospect of such observations up to a distance of 100 Mpc for an optimally oriented and located source with an SNR of 4.

REMARKS: These are the first records from the Adriatic Sea.
Recent studies (Yokohama et al. 2010; Simboura et al. 2010) showed that Paraprionospio specimens from the Turkish Aegean Sea, the Sea of Marmara, the Spanish Mediterranean coast and Greece, belong to Paraprionospio coora Wilson, 1990, instead of P. Pinnata (Ehlers, 1901), previously recognised as a cosmopolitan species being reported from various temperate and tropical waters in the world, including the Mediterranean, and suggested that the former records of P. pinnata from the Mediterranean are questionable. Northern Adriatic specimens analysed in this study are P. coora, thus it is supposed that previous records of P. pinnata in the CA and SA by Castelli et al. (2008) as well belong to that species.

description: In this study, multiscale permeability upscaling is combined with a sensitivity study of model boundary condition to identify an optimal heterogeneity resolution in developing a reservoir model to represent a deep saline aquifer in CO2 storage simulation. A three-dimensional, fully heterogeneous reservoir model is built for a deep saline aquifer in western Wyoming, where each grid cell is identified by multiple material tags. On the basis of these tags, permeability upscaling is conducted to create three increasingly simpler site models, a facies model, a layered model, and a formation model. Accuracy of upscaling is evaluated first, before CO2 simulation is conducted in all models. Since at the injection site, uncertainty exists in the nature of the reservoir compartment, end-member boundary conditions are evaluated, whereby brine production is introduced to control formation fluid pressure. The effect of conceptual model uncertainty on model prediction is then assessed for each boundary condition. Results suggest that for the spatial and temporal scales considered, without brine production, optimal complexity of the upscaled model depends on the prediction metric of interest; the facies model is the most accurate for capturing plume shape, fluid pressure, and CO2 mass profiles, while the formation model is adequate for pressure prediction. The layered model is not accurate for predicting most of the performance metrics. Moreover, boundary condition impacts fluid pressure and the amount of CO2 that can be injected. For the boundary conditions tested, brine production can modulate fluid pressure, affect the direction of mobile gas flow, and influence the accuracy of the upscaled models. In particular, the importance of detailed geologic resolution is weakened when viscous force is strengthened in relation to gravity force. When brine production is active, variability of the predictions by the upscaled models becomes smaller and the predictions are more accurate, suggesting a subtle but important interplay between heterogeneity resolution, fluid driving forces, and model predictions.

description: Counterfactual inference considers a hypothetical intervention in a parallel world that shares some evidence with the factual world. If the evidence specifies a conditional distribution on a manifold, counterfactuals may be analytically intractable. We present an algorithm for simulating values from a counterfactual distribution where conditions can be set on both discrete and continuous variables. We show that the proposed algorithm can be presented as a particle filter leading to asymptotically valid inference. The algorithm is applied to fairness analysis in credit-scoring.
Structural Evolution of Djebel-Debadib Anticline: A Clue to the Regional Tectonic Style of the Tunisian Atlas

description: Djebel Debadib is a northeast trending anticline in the Tunisian Atlas, near El Kef, Tunisia. The core of the anticline consists of a deformed Triassic, gypsum-matrix breccia containing clasts of supratidal dolomite, terrigeneous clastic rocks, and ophites (metabasites). Locally, low-grade metasedimentary rocks, occurring as clasts in the evaporite, may represent fragments of basement rock plucked from salt subcrop during deep-seated flowage. The multiply deformed Triassic rocks are juxtaposed against Cretaceous or younger rocks, and Jurassic and Neocomian strata are not present in outcrop. These characteristics have been cited in many studies to suggest a history of diapirism to explain both the internal structure of the Triassic rocks and the contact relations with the younger rocks. A previously unreported unconformity, developed on the Triassic rocks and overlain by Aptian-Albian strata, indicates that an important period of piercement occurred during the Early Cretaceous for the Djebel Debadib diapir. From the mid-Cretaceous to the late Eocene the continental margin of northern Tunisia was a regional basin in which a thick sequence of carbonate rocks was deposited. Beginning in late Oligocene time, sandy clastic sediments accumulated on the older carbonate rocks above a regional unconformity, and during the middle Miocene Atlas orogeny, numerous northeast-southwest folds deformed the rocks of the Tunisian trough including the diapiric Triassic masses. These folds, commonly boxlike in geometry, were extensively faulted during the late Miocene and Pliocene. A four phase tectonic model is recognized for the Tunisian Atlas: (1) early Mesozoic rifting of the North African continental margin, (2) diapiric emplacement of the Late Triassic-Liassic(?) evaporites into overlying strata beginning in the early Cretaceous, (3) folding of the cover strata in response to regional compression culminating in the middle Miocene Atlas orogeny, (4) the development of transvers grabens during late orogenic normal faulting (latest Miocene to Recent). A major regional décollement is not considered necessary to account for the shortening of the sedimentary cover during the middle Miocene deformation. Rather, the principal driving mechanism of regional crustal shortening was the reactivation of early Mesozoic normal faults as reverse faults that displaced basement rocks. This model implies that the small amount of shortening recorded in the Tunisian Atlas involved active shortening and structural thickening of basement and the concurrent deformation of the sedimentary cover.

description: The concentration of radiation-induced point defects in general materials under irradiation is commonly described by the point defect kinetics equations based on rate theory. However, the parametric uncertainty in describing the rate constants of competing physical processes such as recombination and loss to sinks can lead to a large uncertainty in predicting the time-evolving point defect concentrations. Here, based on the perturbation theory, we derived up to the third order correction to the solution of point defect kinetics equations. This new set of equations enable a full description of continuously changing rate constants, and can accurately predict the solution up to $50\%$ deviation in these rate constants. These analyses can also be applied to reveal the sensitivity of solution to input parameters and aggregated uncertainty from multiple rate constants.

description: Video portrait segmentation (VPS), aiming at segmenting prominent foreground portraits from video frames, has received much attention in recent years. However, simplicity of existing VPS datasets leads to a limitation on extensive research of the task. In this work, we propose a new intricate large-scale Multi-scene Video Portrait Segmentation dataset MVPS consisting of 101 video clips in 7 scenario categories, in which 10,843 sampled frames are finely annotated at pixel level. The dataset has diverse scenes and complicated background environments, which is the most complex dataset in VPS to our best knowledge. Through the observation of a large number of videos with portraits during dataset construction, we find that due to the joint structure of human body, motion of portraits is part-associated, which leads that different parts are relatively independent in motion. That is, motion of different parts of the portraits is imbalanced. Towards this imbalance, an intuitive and reasonable idea is that different motion states in portraits can be better exploited by decoupling the portraits into parts. To achieve this, we propose a Part-Decoupling Network (PDNet) for video portrait segmentation. Specifically, an Inter-frame Part-Discriminated Attention (IPDA) module is proposed which unsupervisedly segments portrait into parts and utilizes different attentiveness on discriminative features specified to each different part. In this way, appropriate attention can be imposed to portrait parts with imbalanced motion to extract part-discriminated correlations, so that the portraits can be segmented more accurately. Experimental results demonstrate that our method achieves leading performance with the comparison to state-of-the-art methods.
GENETIC BIODIVERSITY OF THE EUROPEAN BARNACLE CHTHAMALUS MONTAGUI
Creators: name: FONTANI, SONIA
Publisher: name: University of Plymouth

description: Biodiversity ultimately is genetic diversity. Genetic diversity within species is eroded before negative trends in biodiversity become evident as loss of species or habitats. Hence, monitoring biodiversity at the genetic level may indicate what will happen at higher levels of organisation if the trend is allowed to continue. There is a pervasive belief that marine ecosystems are less vulnerable to biodiversity loss than terrestrial ones, due to marine species' high dispersal ability and connectivity, large geographic ranges, low genetic differentiation among populations and high genetic variation within populations. Many studies offer compelling evidence that it is not so: loss of genetic variation due to natural and anthropogenic factors has been detected even in marine species with potentially high dispersal. In this context the genetic pattern of the European barnacle Chthamalus montagui, a species with high dispersal capability, was investigated from three different perspectives using polymorphic microsatellite loci as molecular markers. The effect of structures created to protect coastal areas in the Adriatic Sea, was investigated to test the hypothesis that artificial substrates can act as "corridors" facilitating gene flow among previously isolated populations. The genetic pattern of central populations was compared to that of peripheral/marginal populations over the range of C. montagui in the UK, to test the hypothesis that marginal and peripheral populations tend to be less genetically variable than central ones. For both studies results were consistent with the formulated hypotheses at the 3 analysed loci. Finally, a broader survey of the NE Atlantic and Mediterranean range of this barnacle was carried out to assess spatial scales of genetic variation. A clear differentiation between Atlantic and Mediterranean samples was detected; however, the major source of genetic variation was within sites at a very small spatial scale. The information gained generates insights for marine genetic management and conservation planning.

description: Lossy compression has become an important technique to reduce data size in many domains. This type of compression is especially valuable for large-scale scientific data, whose size ranges up to several petabytes. Although Autoencoder-based models have been successfully leveraged to compress images and videos, such neural networks have not widely gained attention in the scientific data domain. Our work presents a neural network that not only significantly compresses large-scale scientific data, but also maintains high reconstruction quality. The proposed model is tested with scientific benchmark data available publicly and applied to a large-scale high-resolution climate modeling data set. Our model achieves a compression ratio of 140 on several benchmark data sets without compromising the reconstruction quality. 2D simulation data from the High-Resolution Community Earth System Model (CESM) Version 1.3 over 500 years are also being compressed with a compression ratio of 200 while the reconstruction error is negligible for scientific analysis.

description: Strong mutual interactions correlate elementary excitations of quantum matter and plays a key role in a range of emergent phenomena, from binding and condensation to quantum thermalization and many-body localization. Here, we employ a Rydberg quantum simulator to experimentally demonstrate strongly correlated spin transport in anisotropic Heisenberg magnets, where the magnon-magnon interaction can be tuned two orders of magnitude larger than the magnon hopping strength. In our approach, the motion of magnons is controlled by an induced spin-exchange interaction through Rydberg dressing, which enables coherent transport of a single Rydberg excitation across a chain of ground-state atoms. As the most prominent signature of a giant anisotropy, we show that nearby Rydberg excitations form distinct types of magnon bound states, where a tightly bound pair exhibits frozen dynamics in a fragmented Hilbert space, while a loosely bound pair propagates and establishes correlations beyond a single lattice site. Our scheme complements studies using resonant dipole-dipole interactions between Rydberg states, and opens the door to exploring quantum thermodynamics with ultrastrong interactions and kinetic constraints.

description: We propose a dynamical scoto-seesaw mechanism using a gauged $B-L$ symmetry. Dark matter is reconciled with neutrino mass generation, in such a way that the atmospheric scale arises \textit{a la seesaw}, while the solar scale is \textit{scotogenic}, arising radiatively from the exchange of ``dark'' states. This way we ``explain'' the solar-to-atmospheric scale ratio. The TeV-scale seesaw mediator and the two dark fermions carry different $B-L$ charges. Dark matter stability follows from the residual matter parity that survives $B-L$ breaking. Besides having collider tests, the model implies sizeable charged lepton flavour violating (cLFV) phenomena, including Goldstone boson emission processes.

THE FERRY SERVICE OFFER AN ANALYSIS OF FERRY SERVICES OPERATING FROM AND WITHIN THE UNITED KINGDOM

description: The objective of this study is to investigate the market offer of passenger-car ferry services within and from the United Kingdom. The study is approached from the pomt of view of the provider of the ferry service offer. Initially, it seeks to analyse the existing ferry services offered within and from the United Kingdom by the various operators, and subsequently undertakes an empirical investigation based on the appropriate marketing and management theory. The role of the consumer is, of course, crucial to an understanding of the marketing of ferry services. However, this particular study focuses on the supply of the ferry offer, and may be seen as complementary to earUer studies of ferry consumers and benefits sought. A comparison of on-board facilities and services on 70 ferries operating in the UK in 1994 resulted in the development of a basehne model explaining differences between services according to a wide range of criteria. This led to the development of a conceptual model of the ferry service offer using concepts from services marketing and corporate culture theory. Using cluster analysis it was concluded that the ferry service offer can be described in terms of core, augmented, and inter-product levels. In addition to these three ferry service offer levels the preferred service provider of each particular ferry service element has been identified. Using multiple discriminant analysis it was concluded that the augmented ferry service offer can be explained by differences among Miles & Snow corporate culture types (prospectors, analysers, and defenders). Combining these results, this study provides an explanation of the ferry service offer in terms of product level, preferred provider, and dominant corporate culture, which should prove of both practical and theoretical value.

In the Mediterranean Sea it was recorded along the Aegean and Turkish Levantine coasts (Dagli & Çinar 2008). The Mediterranean specimens were previously confused with P. antennata (Claparède, 1868) (Çinar et al. 2006). Since P. antennata was reported from the whole Adriatic Sea it is possible that some of those records refer to P. paucibranchiata, and thus they should be carefully re-examined.

description: This paper presents a novel distributed approach for solving AC power flow (PF) problems. The optimization problem is reformulated into a distributed form using a communication structure corresponding to a hypergraph, by which complex relationships between subgrids can be expressed as hyperedges. Then, a hypergraph-based distributed sequential quadratic programming (HDQ) approach is proposed to handle the reformulated problems, and the hypergraph-based distributed sequential quadratic programming (HDSQP) is used as the inner algorithm to solve the corresponding QP subproblems, which are respectively condensed using Schur complements with respect to coupling variables defined by hyperedges. Furthermore, we rigorously establish the convergence guarantee of the proposed algorithm with a locally quadratic rate and the one-step convergence of the inner algorithm when using the Levenberg-Marquardt regularization. Our analysis also demonstrates that the computational complexity of the proposed algorithm is much lower than the state-of-art distributed algorithm. We implement the proposed algorithm in an open-source toolbox, i.e., rapidPF, and conduct numerical tests that validate the proof and demonstrate the great potential of the proposed distributed algorithm in terms of communication effort and computational speed.
VICTIMS AND VILLAINS: SUBJECT POSITIONING IN DISCURSIVE RECONSTRUCTIONS OF SEXUAL HARASSMENT
Creators: name: CLARKE, SARAH JANE
Publisher: name: University of Plymouth
Year: 2008

description: This thesis is a feminist informed, discursive research project. Three studies are presented, each designed to explore reconstructions of sexual harassment incidents. The first and second studies were based upon a corpus of interview data, generated specifically for the research project. The author interviewed six women and encouraged detailed discussion about sexual harassment. The third study was conducted utilising media data. The data includes an initial allegation and description of an incident of sexual harassment, in the form of a magazine article, and a collection of published responses written by journalists, academics and members of the public. The data were analysed utilising a 'hybrid' discursive approach that combined the frameworks of conversation analysis and critical discourse analysis to deconstruct both the interactional and ideological components of the discourse. This thesis makes several distinctive contributions to existing literature. Firstly, whilst hybrid analysis has been advocated by others, it has rarely been applied and therefore this project contributes an example of its application. Secondly, the project offers as its focus a deconstruction of subject positions and the function they serve in the allocation of responsibility and accountability of sexual harassment. This is unique in the field. Thirdly, to feminist action and women's emancipation, the project contributes a knowledge and understanding of women's oppressive and constrained experiences. Through knowledge of oppression women's emancipation can be more easily achieved.

Testing gravity with gauge-invariant polarization states of gravitational waves: Theory and pulsar timing sensitivity

description: The determination of the polarization modes of gravitational waves (GWs) and their dispersion relations is a crucial task for scrutinizing the viability of extended theories of gravity. A tool to investigate the polarization states of GWs is the well-known formalism developed by Eardley, Lee, and Lightman (ELL) [Phys. Rev. D 8, 3308 (1973)] which uses the Newman-Penrose (NP) coefficients to determine the polarization content of GWs in metric theories of gravity. However, if the speed of GWs is smaller than the speed of light, the number of NP coefficients is greater than the number of polarizations. To overcome this inconvenience we use the Bardeen formalism to describe the six possible polarization modes of GWs considering general dispersion relations for the modes. The definition of a new gauge-invariant quantity enables an unambiguous description of the scalar longitudinal polarization mode. We apply the formalism to General Relativity, scalar-tensor theories, $f(R)$-gravity, and a wide class of quadratic gravity. We derive an explicit relation between a physical observable (the derivative of the frequency shift of an electromagnetic signal), and the gauge-invariant variables. Then we find an analytical formula for the pulsar timing rms response to each polarization mode. To estimate the sensitivity of a single pulsar timing we focus on the case of a dispersion relation of a massive particle. The sensitivity curves of the scalar longitudinal and vector polarization modes change significantly depending on the value of the effective mass. The detection (or absence of detection) of the polarization modes using the pulsar timing technique has decisive implications for alternative theories of gravity. Finally, investigating a cutoff frequency in the pulsar timing band can lead to a more stringent bound on the graviton mass than that presented by ground-based interferometers.

INTERNATIONAL COLLISION REGULATIONS FOR AUTOMATIC COLLISION AVOIDANCE
Creators: name: PERKINS, CHRISTOPHER JAMES
Publisher: name: University of Plymouth
Year: 1996

description: This thesis considers the relationship between collision regulations and an automatic collision avoidance system (ACAS). Automation of ship operations is increasingly common. The automation of the collision avoidance task may have merit on grounds of reduced manual workload and the elimination of human error. Work to date by engineers and computer programmers has focused on modelling the requirements of the current collision regulations. This thesis takes a new approach and indicates that legislative change is a necessary precursor to the implementation of a fully automatic collision avoidance system. A descriptive analysis has been used to consider the nature of the collision avoidance problem and the nature of rules as a solution. The importance of coordination between vessels is noted and three requirements for coordination are established. These are a mutual perception of: risk, the strategy to be applied, and the point of manoeuvre. The use of rules to achieve coordination are considered. The analysis indicates that the current collision regulations do not provide the means to coordinate vessels. A review of current and future technology that may be applied to the collision avoidance problem has been made. Several ACAS scenarios are contrived. The compatibility of the scenarios and the current collision regulations is considered. It is noted that both machine sensors and processors affect the ability to comply with the rules. The case is made for judicial recognition of a discrete rule-base for the sake of an ACAS. This leads to the prospect of quantified collision regulations for application by mariners. A novel rule-base to match a pm1icular ACAS scenario has been devised. The rules are simple and brief. They avoid inputs dependent on vision and visibility, and meet all the aforementioned coordination requirements. Their application by mariners to two-vessel open sea, encounters was tested on a navigation simulator. The experimental testing of such a rule-base is unique. Mariners were given experience of applying the rule-base in certain circumstances and asked by questionnaire what their agreeable action would be. This was compared with their usual action. While the number of experiments was small, an indication was given of the impm1ant issues in applying a quantified rule-base. Aspects identified for fm1her study include the testing of rule base elements in isolation, and the use of quantified rules in multi-ship and confined water encounters.

description: Recommender systems help people find relevant content in a personalized way. One main promise of such systems is that they are able to increase the visibility of items in the long tail, i.e., the lesser-known items in a catalogue. Existing research, however, suggests that in many situations todays recommendation algorithms instead exhibit a popularity bias, meaning that they often focus on rather popular items in their recommendations. Such a bias may not only lead to the limited value of the recommendations for consumers and providers in the short run, but it may also cause undesired reinforcement effects over time. In this paper, we discuss the potential reasons for popularity bias and review existing approaches to detect, quantify and mitigate popularity bias in recommender systems. Our survey, therefore, includes both an overview of the computational metrics used in the literature as well as a review of the main technical approaches to reduce the bias. Furthermore, we critically discuss todays literature, where we observe that the research is almost entirely based on computational experiments and on certain assumptions regarding the practical effects of including long-tail items in the recommendations.
User-friendly confidence regions for quantum state tomography

description: Quantum state tomography is the standard technique for reconstructing a quantum state from experimental data. In the regime of finite statistics, experimental data cannot give perfect information about the quantum state. A common way to express this limited knowledge is by providing confidence regions in the state space. Though other confidence regions were previously proposed, they are either too wasteful to be of practical interest, cannot easily be applied to general measurement schemes, or are too difficult to report. Here we construct confidence regions that solve these issues, as they have an asymptotically optimal sample cost and good performance for realistic parameters, are applicable to any measurement scheme, and can be described by an ellipsoid in the space of Hermitian operators. Our construction relies on a vector Bernstein inequality and bounds with high probability the Hilbert-Schmidt norm error of sums of multinomial samples transformed by linear maps.

description: A topological 'Thouless' pump represents the quantised motion of particles in response to a slow, cyclic modulation of external control parameters. The Thouless pump, like the quantum Hall effect, is of fundamental interest in physics because it links physically measurable quantities, such as particle currents, to geometric properties of the experimental system, which can be robust against perturbations and thus technologically useful. So far, experiments probing the interplay between topology and inter-particle interactions have remained relatively scarce. Here we observe a Thouless-type charge pump in which the particle current and its directionality inherently rely on the presence of strong interactions. Experimentally, we utilise a two-component Fermi gas in a dynamical superlattice which does not exhibit a sliding motion and remains trivial in the single-particle regime. However, when tuning interparticle interactions from zero to positive values, the system undergoes a transition from being stationary to drifting in one direction, consistent with quantised pumping in the first cycle. Remarkably, the topology of the interacting pump trajectory cannot be adiabatically connected to a non-interacting limit, highlighted by the fact that only one atom is transferred per cycle. Our experiments suggest that Thouless charge pumps are promising platforms to gain insights into interaction-driven topological transitions and topological quantum matter.

description: The prediction of protein 3D structure from amino acid sequence is a computational grand challenge in biophysics, and plays a key role in robust protein structure prediction algorithms, from drug discovery to genome interpretation. The advent of AI models, such as AlphaFold, is revolutionizing applications that depend on robust protein structure prediction algorithms. To maximize the impact, and ease the usability, of these novel AI tools we introduce APACE, AlphaFold2 and advanced computing as a service, a novel computational framework that effectively handles this AI model and its TB-size database to conduct accelerated protein structure prediction analyses in modern supercomputing environments. We deployed APACE in the Delta and Polaris supercomputers, and quantified its performance for accurate protein structure predictions using four exemplar proteins: 6AWO, 6OAN, 7MEZ, and 6D6U. Using up to 300 ensembles, distributed across 200 NVIDIA A100 GPUs, we found that APACE is up to two orders of magnitude faster than off-the-self AlphaFold2 implementations, reducing time-to-solution from weeks to minutes. This computational approach may be readily linked with robotics laboratories to automate and accelerate scientific discovery.

description: Each connected graded, graded-commutative algebra $A$ of finite type over a field $\Bbbk$ of characteristic zero defines a complex of finitely generated, graded modules over a symmetric algebra, whose homology graded modules are called the (higher) Koszul modules of $A$. In this note, we investigate the geometry of the support loci of these modules, called the resonance schemes of the algebra. When $A=\Bbbk\langle Δ\rangle$ is the exterior Stanley-Reisner algebra associated to a finite simplicial complex $Δ$, we show that the resonance schemes are reduced. We also compute the Hilbert series of the Koszul modules and give bounds on the regularity and projective dimension of these graded modules. This leads to a relationship between resonance and Hilbert series that generalizes a known formula for the Chen ranks of a right-angled Artin group.

description: The topology of the electronic band structure of solids can be described by its Berry curvature distribution across the Brillouin zone. We theoretically introduce and experimentally demonstrate a general methodology based on the measurement of energy- and momentum-resolved optical transition rates, allowing to reveal signatures of Berry curvature texture in reciprocal space. By performing time- and angle-resolved photoemission spectroscopy of atomically thin WSe$_2$ using polarization-modulated excitations, we demonstrate that excitons become an asset in extracting the quantum geometrical properties of solids. We also investigate the resilience of our measurement protocol against ultrafast scattering processes following direct chiroptical transitions.
