description: An introduction is given to Clifford Analysis over pseudo-Euclidean space of arbitrary signature, called for short Ultrahyperbolic Clifford Analysis (UCA). UCA is regarded as a function theory of Clifford-valued functions, satisfying a first order partial differential equation involving a vector-valued differential operator, called a Dirac operator. The formulation of UCA presented here pays special attention to its geometrical setting. This permits to identify tensors which qualify as geometrically invariant Dirac operators and to take a position on the naturalness of contravariant and covariant versions of such a theory. In addition, a formal method is described to construct the general solution to the aforementioned equation in the context of covariant UCA.

description: Buildings can be divided into various types and described by a huge number of parameters. Within the life cycle of a building, especially during the design and construction phases, a lot of engineers with different points of view, proprietary applications and data formats are involved. The collaboration of all participating engineers is characterised by a high amount of communication. Due to these aspects, a homogeneous building model for all engineers is not feasible. The status quo of civil engineering is the segmentation of the complete model into partial models. Currently, the interdependencies of these partial models are not in the focus of available engineering solutions. This paper addresses the problem of coupling partial models in civil engineering. According to the state-of-the-art, applications and partial models are formulated by the object-oriented method. Although this method solves basic communication problems like subclass coupling directly it was found that many relevant coupling problems remain to be solved. Therefore, it is necessary to analyse and classify the relevant coupling types in building modelling. Coupling in computer science refers to the relationship between modules and their mutual interaction and can be divided into different coupling types. The coupling types differ on the degree by which the coupled modules rely upon each other. This is exemplified by a general reference example from civil engineering. A uniform formulation of coupling patterns is described analogously to design patterns, which are a common methodology in software engineering. Design patterns are templates for describing a general reusable solution to a commonly occurring problem. A template is independent of the programming language and the operating system. These coupling patterns are selected according to the specific problems of building modelling. A specific meta-model for coupling problems in civil engineering is introduced. In our meta-model the coupling patterns are a semantic description of a specific coupling design.

description: Reducing energy consumption is one of the major challenges for present day and will continue for future generations. The emerging EU directives relating to energy (EU EPBD and the EU Directive on Emissions Trading) now place demands on building owners to rate the energy performance of their buildings for efficient energy management. Moreover European Legislation (Directive 2006/32/EC) requires Facility Managers to reduce building energy consumption and operational costs. Currently sophisticated building services systems are available integrating off-the-shelf building management components. However this ad-hoc combination presents many difficulties to building owners in the management and upgrade of these systems. This paper addresses the need for integration concepts, holistic monitoring and analysis methodologies, life-cycle oriented decision support and sophisticated control strategies through the seamless integration of people, ICT-devices and computational resources via introducing the newly developed integrated system architecture. The first concept was applied to a residential building and the results were elaborated to improve current building conditions.

Year: 2016

description: Heterogeneous tissues, such as blood, contain of a mixture of cell types. Thus, measuring differences in gene expression level in heterogeneous tissues (e.g., healthy controls vs. disease cases) represents a challenge in deciding which cell types contributes to observed gene expression differences. Contribution of gene expression from each cell type to the heterogeneous gene expression level can be modeled using linear regression (LR). Modeling cell type-specific gene expression separately for a group of healthy controls and a group of patients (cases) allows to identify cell type-specific gene expression differences (LRCDE).
Integrated spatial community resilience decision tool unifying social vulnerability indices and relative sea-level rise predictions

Publisher: name: The University of British Columbia
Year: 2015

description: Infrastructure resilience and social resilience have been independently investigated, but have not yet been integrated in the evaluation of preparedness and natural hazard response investments. In this paper, we present an integrated spatial evaluation of vulnerability to relative sea level rise in the US states of Delaware, Maryland, and Virginia. This paper is motivated by the notion that there may be an interaction between community resilience measured by social indicators and community resilience measured by technical vulnerability indicators. We evaluate this hypothesis by creating a decision support tool integrating relative sea level rise (RSLR) and social vulnerability index (SoVI) for those communities delineated by county. These results will be useful to policy makers by explicitly communicating the tradeoffs between SoVI and technical vulnerability, while also illustrating the potential for prioritizing regions based on the interaction between social resilience and infrastructure resilience.

Subjects: subject: stereotypes
subject: prejudice and discrimination
subject: in-group bias

subject: social norms

description: This paper aims to illustrate the origins of prejudice, its relationship to stereotypes, and how it can lead to discrimination. I will also outline potential solutions to reducing prejudice and discrimination. Stereotypes, prejudice, and discrimination are terms that we often use interchangeably, yet they are three conceptually distinct concepts that often overlap. A stereotype can be defined as an over-generalisation of a specific category or group of people based on observations of characteristics from a smaller sample. Stereotypes can be defined as cognitive biases, where we make generalisations about a group of people based on the characteristics of a smaller sample, hence any variation among individuals is ignored. Prejudice, on the other hand, refers to an affective bias where one holds a positive or negative attitude towards someone because of their membership in a particular group. Discrimination can often be a consequence of prejudice and is characterised as the aversive behaviours one expresses towards an individual or group because of their group membership. Implicit biases are arguably dangerous as they can affect our behaviour towards social groups and reproduce unequal treatment of individuals in society. Prejudice and discrimination are pervasive in society and understanding their causes can help us find ways to eradicate them.

description: The present article proposes an alternative way to compute the torsional stiffness based on three-dimensional continuum mechanics instead of applying a specific theory of torsion. A thin, representative beam slice is discretized by solid finite elements. Adequate boundary conditions and coupling conditions are integrated into the numerical model to obtain a proper answer on the torsion behaviour, thus on shear center, shear stress and torsional stiffness. This finite element approach only includes general assumptions of beam torsion which are independent of cross-section geometry. These assumptions essentially are: no in-plane deformation, constant torsion and free warping. Thus it is possible to achieve numerical solutions of high accuracy for arbitrary cross-sections. Due to the direct link to three-dimensional continuum mechanics, it is possible to extend the range of torsion analysis to sections which are composed of different materials or even to heterogeneous beams on a high scale of resolution. A brief study follows to validate the implementation and results are compared to analytical solutions.

Analyse théorique de la Triple Hélice et de la Théorie de Proximité : Une revue systématique de la littérature

Publisher: name: Zenodo
Year: 2024

description: Cette revue systématique de la littérature explore deux théories fondamentales dans le contexte du développement régional et de l'innovation : la théorie de la Triple Hélice et la théorie de la Proximité. La théorie de la Triple Hélice, développée par Etzkowitz et Leydesdorff (1995), souligne l'importance des interactions trilatérales entre les universités, les industries et les gouvernements pour stimuler l'innovation. Les universités jouent un rôle entrepreneurial crucial, les industries transforment les connaissances en produits et services commercialisables, et les gouvernements créent des cadres réglementaires de soutien. En revanche, la théorie de la Proximité, formalisée par Boschma (2005), identifie diverses formes de proximité - géographique, cognitive, organisationnelle, sociale et institutionnelle - comme des facteurs clés facilitant l'innovation. Chaque type de proximité joue un rôle spécifique dans la promotion de la collaboration et de l'échange de connaissances entre les acteurs. Bien que les deux théories soulignent l'importance des interactions pour le développement régional et l'innovation, elles divergent dans leurs approches méthodologiques et conceptuelles, avec la Triple Hélice se concentrant sur des interactions institutionnelles structurées et la théorie de la Proximité examinant les relations interpersonnelles et contextuelles. La revue identifie des complémentarités entre les deux théories, suggérant qu'une perspective combinée offre une compréhension plus holistique des dynamiques de l'innovation. Les recherches futures devraient explorer les dynamiques contextuelles, les variations régionales et développer des cadres théoriques intégrés qui combinent les deux perspectives pour fournir des insights complets sur les mécanismes qui conduisent l'innovation régionale.

description: Within the scheduling of construction projects, different, partly conflicting objectives have to be considered. The specification of an efficient construction schedule is a challenging task, which leads to a NP-hard multi-criteria optimization problem. In the past decades, so-called metaheuristics have been developed for scheduling problems to find near-optimal solutions in reasonable time. This paper presents a Simulated Annealing concept to determine near-optimal construction schedules. Simulated Annealing is a well-known metaheuristic optimization approach for solving complex combinatorial problems. To enable dealing with several optimization objectives the Pareto optimization concept is applied. Thus, the optimization result is a set of Pareto-optimal schedules, which can be analyzed for selecting exactly one practicable and reasonable schedule. A flexible constraint-based simulation approach is used to generate possible neighboring solutions very quickly during the optimization process. The essential aspects of the developed Pareto Simulated Annealing concept are presented in detail.

description: In this paper three different formulations of a Bernoulli type free boundary problem are discussed. By analyzing the shape Hessian in case of matching data it is distinguished between well-posed and ill-posed formulations. A nonlinear Ritz-Galerkin method is applied for discretizing the shape optimization problem. In case of well-posedness existence and convergence of the approximate shapes is proven. In combination with a fast boundary element method efficient first and second order shape optimization algorithms are obtained.

Publisher: name: Zenodo

description: This report presents the advancements in quantum computing techniques for quantitative finance within Use Case 5 (UC5) of the NEASQC project. The research is a collaborative effort among the University of A Coruna (UDC), the Galician Supercomputing Center (CESGA), and the Hong Kong and Shanghai Banking Corporation (HSBC). Each organization brings unique expertise to the project: UDC focuses on theoretical foundations, CESGA on technological implementation, and HSBC on identifying industry-relevant problems.

The research addresses two main areas critical to HSBC: Quantum Accelerated Monte Carlo (QAMC) for option pricing and Quantum Machine Learning (QML) for risk assessment using metrics such as Value at Risk (VaR). These areas are essential for enhancing the efficiency and accuracy of financial modeling and risk management. More specifically, QAMC aims to expedite the option pricing process, while QML provides advanced techniques for risk assessment, offering deeper insights and more robust predictions.

Despite significant progress, the integration of these quantum techniques into industrial applications remains challenging due to current hardware limitations and the early stage of quantum computing technology. The project highlights the need for further development of quantum hardware and algorithms to bridge the technological gap between classiccal and quantum methods.Notable advancements include new techniques for QAMC and QML, which are particularly relevant for financial institutions. The project has also produced five research papers and developed a comprehensive software library, QQuantLib, to facilitate further research and experimentation.

In conclusion, while significant progress has been made in developing quantum algorithms for pricing and VaR estismation, these algorithms are not yet enough competitive with classical algorithms on current Noisy Intermediate-Scale Quantum (NISQ) architectures. The primary challenges for moving forward are related to the execution of QAMC and QML algorithms, which require both deeper circuits (more layers of gates) and wider circuits (more qubits) than are currently feasible on available quantum hardware.
title: Divide and Conquer: Mind–Body Dualisms in Language and Body Image among Transmasculine Young Adults in Urban Finland

description: Contemporary discussion in urban Finland surrounding transgender activism, healthcare, and politics is characterised by a series of tensions which, I argue, exist not only between institutions and people but also within the imaginaries of individuals. My argument is based on an ethnographic examination of the way in which Finnish linguistic particularities in relation to the concept of sex/gender result in a set of dualistic understandings of the relationship between mind and body, with specific reference to transmasculine identity, transition, and detransition. Essential to these dualisms in the context of Finnish transmasculinity is the desire to hormonally or surgically modify one’s physique, which I present as contingent upon language and life histories. Despite drawing from and building upon anthropological works on “embodiment”, which offer a constructionist approach to sensations often interpreted in medical contexts as innate, I contest the view of biological sex as a naturalised social construct alongside highlighting the limitations of analyses that assume bodies and minds to be separable from one another.

description: Oxidative stress injury (OSI) is involved in brain injury induced by cardiac arrest (CA)/cardiopulmonary resuscitation (CPR), and endoplasmic reticulum stress (ERS) is closely related to OSI. Mild hypothermia (MT) has been used to treat different kinds of brain injury but the mechanism remains unclear. Therefore, this study aimed to examine the effects of MT on OSI in a rat model of CA/CPR and determine the relationship between MT and ERS. The rats were divided into the sham, non-hypothermia (NT), and MT groups, which were then each divided into two subgroups consisting of rats that were sacrificed at 4.5 h and 24 h after the return of spontaneous circulation, respectively (NT-4.5, NT-24, MT-4.5, and MT-24 subgroups) (n = 6). A CA/CPR model was established by asphyxiation in the NT and MT groups, and MT was administered to rats in the MT group. Roughly 73% (24/33) of the rats survived until the end of the study. Compared with the sham group, the neurological deficit score (NDS) decreased, and the OSI, apoptosis, water content increased after model establishment (p 0.05). Compared with those in the NT-4.5 and NT-24 groups, rats in the MT-4.5 and MT-24 groups showed improved NDS (65.3 ± 5.1 vs. 52.8 ± 4.7; 59.7 ± 6.0 vs. 50.5 ± 5.4), lower MDA activity (4.7 ± 0.3 vs. 6.5 ± 0.6; 5.1 ± 0.4 vs. 7.7 ± 0.6) (nmol mg-1 protein), higher SOD (84.7 ± 5.2 vs. 67.4 ± 5.8; 73.9 ± 6.4 vs. 55.8 ± 4.1) (U mg-1 protein) and CAT activities (83.1 ± 6.9 vs. 77.2 ± 6.5; 71.9 ± 3.6 vs. 62.7 ± 4.9) (U mg-1 protein), lower water content (79.2 ± 1.1% vs. 80.6 ± 0.8%; 81.0 ± 0.9% vs. 83.7 ± 1.7%), and lower expression of the ERS-related proteins GRP78, CHOP, caspase-12, and cleaved-caspase-3 (p 0.05). The results also showed that after the MT was stopped, the effects were maintained for a period of time. In conclusion, MT protected against brain injury induced by CA/CPR by decreasing OSI by inhibiting of ERS.

description: Several results concerning the distribution of the headway of busses in the flow behind a traffic signal are presented. In the main focus of interest is the description of analytical models, which are verified by the results of Monte-Carlo-Methods. The advantage of analytical models (verified, but not derived by simulation methods) is their flexibility with respect to possible generalizations. For instance, several random distributions of the flow incoming to the traffic signal can be compared. The attention will be directed at the question, how the primary headway H (analyzed in front of the traffic signal) is mapped to the headway H’ analyzed behind of the traffic signal and how the random distribution of H is mapped to that of H’. For the traffic flow in front of the traffic signal several models will be discussed. The first case considers the situation, that busses operate on a common lane with the individual motor car traffic and the traffic flow is saturated. In the second situation, busses operate on a separated bus lane. Moreover, a mixed situation is discussed to model as close to reality as possible.

Year: 2015

description: This study is an application of a previously developed framework for assessing seismic resilience in infrastructure systems. The risk and resilience framework, accounts for uncertainties in the process including the correlation of the earthquake intensity measures, fragility assessment of structural components, estimation of repair requirements, the repair process, and finally the service demands. The framework, which as already been applied within a case study for the seismic resilience of a seaport, has been extended to show the utility of and results that can be produced when the methodology is used to compare various infrastructure system mitigation options. This study, which also uses seismic resilience in seaports as a case study, compares two operational mitigation options within the methodology: series repair sequencing post-earthquake versus parallel repair sequencing post-earthquake. Results of this analysis show that for a large earthquake event, repair sequencing done in parallel results in a more resilient infrastructure system than for series repair sequencing. The proposed methodology will allow port stakeholders a means to quantitatively compare mitigation options and their overall effect on the seaport system.

description: This research aims to model Alkali-Silica Reaction gel expansion in concrete under the influence of hygral and thermal loading, based on experimental results. ASR provokes a heterogeneous expansion in concrete leading to dimensional changes and eventually the premature failure of the concrete structure. This can result in map cracking on the concrete surface which will decrease the concrete stiffness. Factors that influence ASR are parameters such as the cement alkalinity, the number of deleterious silica from the aggregate used, concrete porosity, and external factors like temperature, humidity and external source of alkali from ingression of deicing salts. Uncertainties of the influential factors make ASR a difficult phenomenon to solve; hence my approach to this matter is to solve the problem using stochastic modelling, where a numerical simulation of concrete cross-section with integration of experimental results from Finger-Institute for Building Materials Science at the Bauhaus-Universität Weimar. The problem is formulated as a multi-field problem, combining heat transfer, fluid transfer and the reaction rate model with the mechanical stress field. Simulation is performed as a mesoscale model considering aggregates and mortar matrix. The reaction rate model will be conducted using experimental results from concrete expansions due to ASR gained from concrete prism tests. Expansive strains values for transient environmental conditions due to the reaction rate will be determined from calculation based on the reaction rate model. Results from these models will be able to predict the rate of ASR expansion and the cracking propagation that may arise.

Publisher: name: The University of British Columbia
Year: 2015

description: An algorithm based on kriging statistical interpolation for computing the surrogate response of a Finite Element model is presented. The interpolation model is calibrated via computation of Finite Element responses at a set of random occurrences of a material parameter. Such random generation concentrates at locations where the numerical model requires a higher amount of data to get the desired accuracy. As a model problem a standard fracture propagation test is analyzed. The proposed procedure is shown to be robust and accurate since responses obtained via a direct computation and use of the surrogate model turn out to be undistinguishable.

description: The evident advances of the computational power of the digital computers enable the modeling of the total system of structures. Such modeling demands compatible representations of the couplings of different structural subsystems. Therefore, models of dynamic interaction between the vehicle and the bridge and models of a bridge bearing, a coupling element between the bridge's superstructure and substructure, are of interest and discussed within this paper. The vehicle-bridge interaction may be described as a function connecting two sets of behavior. In this case, the coupling is embodied by mutual parameters that affect both systems, such as the frequency content of the bridge and the vehicle. Whereas the bridge bearings are elements used specifically to couple, in such elements the deformation and the transferred loads are used in characterizing the coupling The nature of these couplings and their influence on the bridge response is different. However, the need to assess the amount of dynamic response transferred by or within these couplings is a common argument.

The reasons for that as well as additional material phenomena are explained in the following paper. Existing creep models developed for standard concrete are studied to determine the time-dependent deformations of PCC. These models are: model B3 by Bažant and Bajewa, the models according to Model Code 90 and ACI 209 as well as model GL2000 by Gardner and Lockman. The calculated creep strains are compared to existing experimental data of PCC and the differences are pointed out. Furthermore, an optimization of the model parameters is performed to fit the models to the experimental data to achieve a better model prognosis.

description: In order to make control decisions, Smart Buildings need to collect data from multiple sources and bring it to a central location, such as the Building Management System (BMS). This needs to be done in a timely and automated fashion. Besides data being gathered from different energy using elements, information of occupant behaviour is also important for a building’s requirement analysis. In this paper, the parameter of Occupant Density was considered to help find behaviour of occupants towards a building space. Through this parameter, support for building energy consumption and requirements based on occupant need and demands was provided. The demonstrator presented provides information on the number of people present in a particular building space at any time, giving the space density. Such collections of density data made over a certain period of time represents occupant behaviour towards the building space, giving its usage patterns. Similarly, inventory items were tracked and monitored for moving out or being brought into a particular read zone. For both, people and inventory items, this was achieved using small, low-cost, passive Ultra-High Frequency (UHF) Radio Frequency Identification (RFID) tags. Occupants were given the tags in a form factor of a credit card to be possessed at all times. A central database was built where occupant and inventory information for a particular building space was maintained for monitoring and providing a central data access.

description: This is a report on the DECI (Distributed Extreme Computing Initiative) calls which took place within the T2.6 task. It also includes recommendations and plans for future DECI Calls. Statistics are presented for the relevant DECI calls which give an overview of the number and type of proposals received and those funded. This report focuses on the DECI-11 and DECI-12 calls which were handled entirely within T2.6. Special mention is made of the new on-line submission system, the PRACE Peer Review (PPR) tool, developed by CINES which came into operation for DECI-11 giving rise to a big improvement to the way in which DECI proposals are handled. The efficiency of the PPR tool was of particular importance for DECI-11 as we received a record number of proposals for this call (117 of which 115 were eligible). The number of proposals received for the most recent call, DECI-12, was lower with 61 proposals received (still a large number of proposals), but this was expected as the call was not advertised as widely and the call was open for less time than usual (just under 5 weeks which included the Christmas holiday period compared with approximately 6 weeks for most DECI calls including no major holiday periods). The reason why this lower number was intended was that DECI-12 will have to run partly after the end of PRACE-3IP and so will have fewer resources available in terms of number of machines, CPU hours and staff effort. DECI continues to be popular with Principal Investigators (PIs) and the number of proposals remains high. Scientific results are not described in this document as they are highlighted in the PRACE Digest 3/2013.

description: Geotechnical constructions are sophisticated structures due to the non-linear soil behaviour and the complex soil-structure interaction, which entails great exigencies on the liable engineer during the design process. The process can be schematised as a difficult and, depending on the opportunities and skills of the processor more or less innovative, creative and heuristic search for one or a multiple of defined objectives under given boundary conditions. Wholistic approaches including numerical optimisation which support the constructing engineer in this task do not currently exist. Abstract problem formulation is not state of the art; commonly parameter studies are bounded by computational effort. Thereby potential regarding cost effectiveness, construction time, load capacity and/or serviceability are often used insufficiently. This paper describes systematic approaches for comprehensive optimisation of selected geotechnical constructions like combined pile raft foundations and quay wall structures. Several optimisation paradigms like the mono- and the multi-objective optimisation are demonstrated and their use for a more efficient design concerning various intentions is shown in example. The optimisation is implemented by using Evolutionary Algorithms. The applicability to geotechnical real world problems including nonlinearities, discontinuities and multi-modalities is shown. The routines are adapted to common problems and coupled with conventional analysis procedures as well as with numerical calculation software based on the finite element method. Numerical optimisation of geotechnical design using efficient algorithms is able to deliver highly effective solutions after investing more effort into the parameterization of the problem. Obtained results can be used for realizing different constructions near the stability limit, visualizing the sensitivity regarding the construction parameters or simply procuring more effective solutions.

title: Limb articulation of biological motion can induce illusory motion perception during self-motion

description: When one walks toward a crowd of pedestrians, dealing with their biological motion while controlling one's own self-motion is a difficult perceptual task. Limb articulation of a walker is naturally coupled to the walker's translation through the scene and allows the separation of optic flow generated by self-motion from the biological motion of other pedestrians. Recent research has shown that if limb articulation and translation mismatch, such as for walking in place, self-motion perception becomes biased. This bias may reflect an illusory motion attributed to the pedestrian crowd from the articulation of their limbs. To investigate this hypothesis, we presented observers with a simulation of forward self-motion toward a laterally moving crowd of point-light walkers and asked them to report the perceived lateral speed of the crowd. To investigate the dependence of the crowd speed percept on biological motion, we also included conditions in which the points of the walker were spatially scrambled to destroy body form and limb articulation. We observed illusory crowd speed percepts that were related to the articulation rate of the biological motion. Scrambled walkers also produced illusory motion but it was not related to articulation rate. We conclude that limb articulation induces percepts of crowd motion that can be used for interpreting self-motion toward crowds.

Benchmark suite

description: This deliverable present the results of running the Unified European Application Benchmark Suite (UEABS), a set of 12 application codes selected in the PRACE Second Implementation Phase (PRACE-2IP) project from the pre-existing PRACE and DEISA application benchmark suites, on PRACE Tier-0 architectures. This work has been undertaken by Task 7.3 “Support for European Researchers” in the PRACE Third Implementation Phase (PRACE-3IP) project and is an extension of the work carried out in Task 7.4 “Unified European Applications Benchmark Suite for Tier-0 and Tier-1” in the PRACE Second Implementation Phase (PRACE-2IP) project. The results demonstrate that for some benchmarks there are significant differences in the performance obtained on the different architectures, and no one architecture gives the best performance on all the benchmarks.

description: Self-centering concentrically braced frame (SC-CBF) systems have been developed to increase the drift capacity of braced frames prior to structural damage. To achieve the improved seismic performance of SC-CBF system, the construction cost of an SC-CBF is expected to be higher than that of a conventional CBF. In this study, economic effectiveness of using an SC-CBF instead of a CBF in one prototype building is calculated to indicate the time that initial SC-CBF construction costs are compensated by lower earthquake-induced losses in the lifetime of the building (pay-off time). The results of this study show lower business interruption is the most significant component of the economic benefit of the SC-CBF compared to the CBF. Moreover, the pay-off time increases dramatically if the initial construction cost of the SC-CBF is more than 4% higher than the CBF.

description: Earthquake ground motion recordings are scarce in the central and eastern U.S. (CEUS) for large magnitude events and at close distances. We use two different simulation approaches, a deterministic physics-based model and a stochastic model, to simulate recordings from the 2011 Mineral, Virginia, 𝑀𝑤 5.8 earthquake in the CEUS. We then use the 2001 Bhuj, India, 𝑀𝑤 7.6 earthquake as a tectonic analog for a large CEUS earthquake and modify our simulations to develop models for generation of large magnitude earthquakes in the CEUS. Both models show a good fit to the observations from 0.1 to 10 Hz, and show a faster fall-off with distances beyond 500 km for the acceleration spectra compared to ground motion prediction models (GMPEs) for a 𝑀𝑤 7.6 event.
