title: Procuring Complex Products and Services: An Assessment of Acquisition Lifecycle Strategies and Practices
Creators: name: Forster, R
Publisher: name: University of Liverpool Repository
Year: 2023

description: This research examined the processes that define the acquisition lifecycles of organisations procuring major assets in complex environments. The research used a multiple case study approach within an abductive research design in order to explore the approaches taken towards solving the problem of effectively procuring within these complex contexts. High-profile, public and private organisations operating in the Defence, Nuclear, Local Government, Health, Manufacturing and Technology sectors are analysed over a four year period. The research utilised a novel means of cross-case examination based on the Zachman enterprise mapping technique in order to derive a comprehensive understanding of processes embedded in complex organisations’ acquisition lifecycles. The requirement for complex contracting for an increasingly diverse range of products and services continues to grow, particularly in the public sector where organisations heavily focus on their core competencies and procure a significant proportion of their requirements from the private sector. Thus this work seeks to address increasing calls for actionable insights from major UK institutions and the academic literature. Current work into the area has been described as ‘provider-active. This work seeks to redress this by focusing on generating insights from the procurer’s perspective. The research identified 18 categories of potential process difference amongst the cases of complex procurers. The research suggests that differences within these 18 categories explain the majority of functional differences emerging from the body of cases, and thus can act as a means by which organisations could benchmark against other organisations operating within a PCP (Procuring Complex Performance) domain. By considering differences in these categories the work highlights three major types of complex procurer: partially-enabled reactors, moderately-enabled conformers and fully-enabled architects. These three categories vary in their capacity to manage complex performance, the complexity of their environments as well as the perceived effectiveness of their current acquisition lifecycle practices. This classification forms a major theoretical contribution of the thesis. The research has articulated the strategic positions taken toward procuring complex products and services within each case by identifying and analysing the processes embedded along the entirety of the acquisition lifecycle that are classified in the aforementioned categories. In doing so, the research provides both theoretical knowledge to the current academic literature, most notably PCP, as well as having provided actionable insights of benefit to procurement practitioners and policy makers.

description: In this article, we propose a novel standalone hybrid Spiking-Convolutional Neural Network (SC-NN) model and test on using image inpainting tasks. Our approach uses the unique capabilities of SNNs, such as event-based computation and temporal processing, along with the strong representation learning abilities of CNNs, to generate high-quality inpainted images. The model is trained on a custom dataset specifically designed for image inpainting, where missing regions are created using masks. The hybrid model consists of SNNConv2d layers and traditional CNN layers. The SNNConv2d layers implement the leaky integrate-and-fire (LIF) neuron model, capturing spiking behavior, while the CNN layers capture spatial features. In this study, a mean squared error (MSE) loss function demonstrates the training process, where a training loss value of 0.015, indicates accurate performance on the training set and the model achieved a validation loss value as low as 0.0017 on the testing set. Furthermore, extensive experimental results demonstrate state-of-the-art performance, showcasing the potential of integrating temporal dynamics and feature extraction in a single network for image inpainting.

description: La campagne Magofond 3, réalisée en 2005, visait à exploiter cette découverte en se focalisant sur un événement géomagnétique exceptionnel, la « période magnétique calme » du Crétacé (83-118 Ma). Cette période est un long épisode au cours duquel aucune inversion n'est observée et la polarité du champ semble être restée normale. L'objectif de la campagne Magofond 3 était donc d'acquérir de longs profils magnétiques de haute résolution à travers la « zone magnétique calme » Crétacée de l'océan Atlantique Central, entre les îles Canaries et du Cap Vert. Les profils devaient être réalisés de manière à éviter tout mont sous-marin et toute complexité tectonique, susceptibles de brouiller le message temporel porté par les anomalies magnétiques océaniques. Pour cela, la première partie de la campagne (de 2 semaines) avait consisté en un levé géophysique conventionnel suivant plusieurs profils considérés comme des cibles potentielles, de manière à choisir ceux qui présentent les conditions les plus favorables à la réalisation de profils de haute résolution.
Cette partie a été réalisée de manière très satisfaisante, permettant l'acquisition de données de sismique rapide et de magnétisme de surface le long de deux profils traversant complètement la zone magnétique calme, de deux profils en recoupant la moitié la plus jeune et d'un dernier profil le quart le plus ancien.
La seconde partie de la campagne (de 3 semaines), dédiée exclusivement à la réalisation des profils de haute résolution par magnétomètre de fond tracté à petite vitesse, a par contre été perturbée par différents problèmes techniques, conduisant à la destruction d'un instrument et à l'acquisition - à l'aide d'un instrument de fortune, adapté à bord - de deux courts profils à une profondeur de 4000 m, le premier à travers la partie la plus jeune de la zone calme, le second à travers sa partie la plus ancienne.La demande de campagne Magofond 3b - réalisée sous le nom de Magofond 08 de par l'année de sa réalisation - visait à remplir les objectifs de la seconde partie de la campagne Magofond 3, soit la réalisation d'un profil magnétique de haute résolution, acquis à proximité du fond. La campagne sensu stricto a été précédée d'une série de tests techniques concluants, réalisés en juillet 2008 sur le N/O Pourquoi pas ? au large de Brest.

description: We consider edge decompositions of $K_v^{(3)}-I$, the complete 3-uniform hypergraph of order $v$ minus a 1-factor (parallel class, packing of $v/3$ disjoint edges). We prove that a decomposition into tight 6-cycles exists if and only if $v\equiv 0,3,6$ (mod 12) and $v\geq 6$; and a decomposition into tight 9-cycles exists for all $v\geq 9$ divisible by 3. These results are complementary to the theorems of Akin et al. [Discrete Math. 345 (2022)] and Bunge et al. [Australas. J. Combin. 80 (2021)].

title: Structure-function study of heteromeric amino acid transporter, LAT1-CD98hc
Creators: name: Chiduza, GN
Publisher: name: University of Liverpool Repository
Year: 2019

description: The L-type neutral amino acid transporter 1 (LAT1/SLC7A5) is one of 7 light chains that can form a heteromeric amino acid transporter (HAT) with the type II single pass glycoprotein CD98hc (SLC3A2). LAT1-CD98hc transports essential amino acids and some of their catabolites, such as tryptophan, methionine and kynurenine, across the plasma membranes of normal and cancer cells. It is also a drug transporter, carrying drugs such as gabapentin and L-DOPA across the blood brain barrier. The atypical heterodimeric nature of LAT1-CD98hc and its role in disease and drug delivery, motivate the structural characterisation of the HAT. Sequence analysis revealed two putative cholesterol binding motifs conserved between dDAT and LAT1 as well as 32 putative CRAC/CARC motifs. The crystal structures of various bacterial homologues of LAT1 were used for structure prediction, in order to visualise these putative cholesterol binding motifs and assess their plausibility. Here is presented the first binding mode analysis of ligands to the inward facing occluded conformation of LAT1. Substrates had lower predicted free energies of binding to the inward facing conformation compared to the outward open. The putative gating residue F252 may play a role in binding to aromatic substrates via p-p stacking in the outward open conformation and with all substrates via p-cation bonding with their amino termini in the inward facing occluded conformation. Based on the docking analysis, inhibitors of LAT1, JPH203 and SKN203 are predicted to transportable substrates of the transporter and KMH233 a non-transportable competitive inhibitor with a unique binding mode. LAT1 was overexpressed in HEK293 cells and co-purified with CD98hc to a sufficient biochemical homogeneity for structural characterisation. The role of cholesterol hemisuccinate in stabilizing detergent solubilized LAT1-CD98hc was established. Detergent solubilized and purified LAT1-CD98hc was subject to structural analysis by single particle electron cryo-microscopy to a resolution of 12 Å. Multibody 3D auto-refinement and principal component analysis revealed flexibility and limited interaction between CD98hc ectodomain and LAT1, contrary to predictions based on homology to LAT2-CD98hc. Docking of CD98hc allowed for visualisation and generation of molecular movies of the structural dynamics of LAT1- CD98hc ectodomain, based on these the ectodomain of CD98hc seems tethered to LAT1 via the inter-subunit disulphide bond and interaction between their transmembrane domains.
Convergence for Complex Gaussian Multiplicative Chaos on phase boundaries

Year: 2023
Subjects: subject: Probability (math.PR)

description: The complex Gaussian Multiplicative Chaos (or complex GMC) is informally defined as a random measure $e^{γX} \mathrm{d} x$ where $X$ is a log correlated Gaussian field on $\mathbb R^d$ and $γ=α+iβ$ is a complex parameter. The correlation function of $X$ is of the form $$ K(x,y)= \log \frac{1}{|x-y|}+ L(x,y),$$ where $L$ is a continuous function. In the present paper, we consider the cases $γ\in \mathcal P_{\mathrm{I/II}}$ and $γ\in \mathcal{P}'_{\mathrm{II/III}}$ where $$ \mathcal P_{\mathrm{I/II}}:= \{ α+i β\ : α,β\in \mathbb R \ ; |α|>|β| \ ; \ |α|+|β|=\sqrt{2d} \}, $$ and $$ \mathcal{P}'_{\mathrm{II/III}}:= \{ α+i β\ : α,β\in \mathbb R \ ; \ |α|= \sqrt{d/2} \ ; \ |β|>\sqrt{2d} \},$$ We prove that if $X$ is replaced by an approximation $X_ε$ obtained via mollification, then $e^{γX_ε} \mathrm{d} x$, when properly rescaled, converges when $ε\to 0$. The limit does not depend on the mollification kernel. When $γ\in \mathcal P_{\mathrm{I/II}}$, the convergence holds in probability and in $L^p$ for some value of $p\in [1,\sqrt{2d}/α)$. When $γ\in \mathcal{P}'_{\mathrm{II/III}}$ the convergence holds only in law. In this latter case, the limit can be described a complex Gaussian white noise with a random intensity given by a critical real GMC. The regions $\mathcal P_{\mathrm{I/II}}$ and $ \mathcal{P}'_{\mathrm{II/III}}$ correspond to phase boundary between the three different regions of the complex GMC phase diagram. These results complete previous results obtained for the GMC in phase I and III and only leave as an open problem the question of convergence in phase II.

title: Prehistoric vegetation change and woodland management in central Anatolia: late Pleistocene-mid Holocene anthracological remains from the Konya Plain
Creators: name: Kabukcu, C
Publisher: name: University of Liverpool Repository
Year: 2015

description: This thesis presents the results of the analysis of the anthracological remains (charred fuel wood waste debris) retrieved from the archaeological sites of Pınarbaşı, Boncuklu, Can Hasan III, Çatalhöyük East and Çatalhöyük West, located in the Konya plain of south-central Anatolia, Turkey. Together, these sites span the time period between ~15-7.5 ka cal. BP. The main aims of the present study are: (a) to characterise the use of prehistoric woodlands in south-central Anatolia and its changes through time during this critical period for the development of settled life and early agricultural economies, (b) to investigate the nature and scale of woodland management activities and anthropogenic impacts on prehistoric woodland vegetation, and (c) to assess the representativeness of the anthracological assemblages for reconstructing the composition, structure, form and distribution of late Pleistocene and early to mid-Holocene woodland vegetation in south-central Anatolia, and its changing ecologies in relation to climate, woodland growth conditions and human impacts. Anthracological analyses focused on charcoal macro-remains retrieved from a range of primary (fire features) and secondary (middens, building infill, and general dispersed contexts) fuel wood waste deposits. The methodologies applied included the taphonomic assessment of charcoal densities, standard taxon frequency and ubiquity quantitative analyses, and the quantitative and qualitative analysis of wood calibre and the dendroecological features preserved in archaeological charcoal specimens. The results of these analyses were further explored through the application of a range of multivariate quantitative techniques. The same techniques were also used to integrate the results of anthracological analyses with dung fuel seed archaeobotanical and select hunted and herded faunal datasets, in order to evaluate their co-variation, and thus reconstruct the co-evolution of landscape practices and anthropogenic impacts across space and time. This thesis demonstrates the unique potential of anthracology to provide novel and highly original insights in the palaeoecology and palaeoeconomy of Southwest Asia, particularly with regard to the investigation of vegetation history, the origin and developments of early anthropogenic landscapes and the nature of people-environment interactions during the transition from foraging to farming.

description: From ride-hailing to car rentals, consumers are often presented with eco-friendly options. Beyond highlighting a "green" vehicle and CO2 emissions, CO2 equivalencies have been designed to provide understandable amounts; we ask which equivalencies will lead to eco-friendly decisions. We conducted five ride-hailing scenario surveys where participants picked between regular and eco-friendly options, testing equivalencies, social features, and valence-based interventions. Further, we tested a car-rental embodiment to gauge how an individual (needing a car for several days) might behave versus the immediate ride-hailing context. We find that participants are more likely to choose green rides when presented with additional information about emissions; CO2 by weight was found to be the most effective. Further, we found that information framing - be it individual or collective footprint, positive or negative valence - had an impact on participants' choices. Finally, we discuss how our findings inform the design of effective interventions for reducing car-based carbon-emissions.

description: While most industrial processes that include metal deposition use elevated temperatures, the majority of scientific investigations are done at room temperature. Thus, an electrochemical study of the effect of the temperature on the metal deposition was seen as necessary. For a basic study, the underpotential deposition (UPD) was chosen to be investigated as a controlled amount of metal can be deposited. The copper underpotential deposition (Cu-UPD) on Au(111) in sulphuric acid was chosen due to being a well-known model system. As the sulphate anion strongly influences the UPD process, perchloric acid was also studied to investigate the dependence on the strength of the adsorbing anion. To see whether or not the temperature dependence was only due to the metal deposition, the copper-free electrolytes were also investigated. For the metal-free electrolytes, only cyclic voltammetry was used. For the Cu-UPD the study used both cyclic voltammetry and chronoamperometry. The temperature range for the study was between 10°C and 55°C. It was found that the increase of the kinetic energy due to the increasing temperature affects the speed of the processes. Moreover, it affects the stability of the formed phases, especially for mobile adlayers. Additionally, alloying was seen for the Cu-UPD on Au(111) in perchloric acid.

description: Heterogeneous collaborative computing with NPU and CPU has received widespread attention due to its substantial performance benefits. To ensure data confidentiality and integrity during computing, Trusted Execution Environments (TEE) is considered a promising solution because of its comparatively lower overhead. However, existing heterogeneous TEE designs are inefficient for collaborative computing due to fine and different memory granularities between CPU and NPU. 1) The cacheline granularity of CPU TEE intensifies memory pressure due to its extra memory access, and 2) the cacheline granularity MAC of NPU escalates the pressure on the limited memory storage. 3) Data transfer across heterogeneous enclaves relies on the transit of non-secure regions, resulting in cumbersome re-encryption and scheduling.
 To address these issues, we propose TensorTEE, a unified tensor-granularity heterogeneous TEE for efficient secure collaborative tensor computing. First, we virtually support tensor granularity in CPU TEE to eliminate the off-chip metadata access by detecting and maintaining tensor structures on-chip. Second, we propose tensor-granularity MAC management with predictive execution to avoid computational stalls while eliminating off-chip MAC storage and access. Moreover, based on the unified granularity, we enable direct data transfer without re-encryption and scheduling dilemmas. Our evaluation is built on enhanced Gem5 and a cycle-accurate NPU simulator. The results show that TensorTEE improves the performance of Large Language Model (LLM) training workloads by 4.0x compared to existing work and incurs only 2.1% overhead compared to non-secure training, offering a practical security assurance for LLM training.

Here we explore the use of a genetic algorithm to retrieve the topology of a network from the measured probability distribution obtained from the evolution of a continuous-time quantum walk on the network. Our result shows that the algorithm is capable of efficiently retrieving the required information even in the presence of noise.

description: Achieving carbon neutrality within industrial operations has become increasingly imperative for sustainable development. It is both a significant challenge and a key opportunity for operational optimization in industry 4.0. In recent years, Deep Reinforcement Learning (DRL) based methods offer promising enhancements for sequential optimization processes and can be used for reducing carbon emissions. However, existing DRL methods need a pre-defined reward function to assess the impact of each action on the final sustainable development goals (SDG). In many real applications, such a reward function cannot be given in advance. To address the problem, this study proposes a Performance based Adversarial Imitation Learning (PAIL) engine. It is a novel method to acquire optimal operational policies for carbon neutrality without any pre-defined action rewards. Specifically, PAIL employs a Transformer-based policy generator to encode historical information and predict following actions within a multi-dimensional space. The entire action sequence will be iteratively updated by an environmental simulator. Then PAIL uses a discriminator to minimize the discrepancy between generated sequences and real-world samples of high SDG. In parallel, a Q-learning framework based performance estimator is designed to estimate the impact of each action on SDG. Based on these estimations, PAIL refines generated policies with the rewards from both discriminator and performance estimator. PAIL is evaluated on multiple real-world application cases and datasets. The experiment results demonstrate the effectiveness of PAIL comparing to other state-of-the-art baselines. In addition, PAIL offers meaningful interpretability for the optimization in carbon neutrality.

description: The field of evolutionary many-task optimization (EMaTO) is increasingly recognized for its ability to streamline the resolution of optimization challenges with repetitive characteristics, thereby conserving computational resources. This paper tackles the challenge of crafting efficient knowledge transfer mechanisms within EMaTO, a task complicated by the computational demands of individual task evaluations. We introduce a novel framework that employs a complex network to comprehensively analyze the dynamics of knowledge transfer between tasks within EMaTO. By extracting and scrutinizing the knowledge transfer network from existing EMaTO algorithms, we evaluate the influence of network modifications on overall algorithmic efficacy. Our findings indicate that these networks are diverse, displaying community-structured directed graph characteristics, with their network density adapting to different task sets. This research underscores the viability of integrating complex network concepts into EMaTO to refine knowledge transfer processes, paving the way for future advancements in the domain.

description: CHSPR's 17th annual health policy conference — As Good as It Gets? Strategies for Improving Chronic Care Management—brought together researchers, clinicians and high-level public servants from B.C. and the United States to discuss the challenges and opportunities surrounding chronic disease management. While British Columbia is ahead of the rest of Canada in this area, we're still at the beginning of a long journey. There was a general consensus among conference participants that there is an emerging global epidemic of chronic illness, and that the current system, which is focused on acute conditions, is not dealing with it effectively. The importance of co-morbidity—multiple chronic conditions—in the management of chronic illness care and in health planning was also recognized. The 'chronic care model' was a key point of reference in most discussions. Several chronic disease management initiatives were described, both from B.C. and from other jurisdictions, along with various methods of measuring chronic illness care. And there was both optimism and apprehension about how we are doing in our efforts to improve the way we care for people with chronic conditions.

description: With the increasing research attention on fairness in information retrieval systems, more and more fairness-aware algorithms have been proposed to ensure fairness for a sustainable and healthy retrieval ecosystem. However, as the most adopted measurement of fairness-aware algorithms, group fairness evaluation metrics, require group membership information that needs massive human annotations and is barely available for general information retrieval datasets. This data sparsity significantly impedes the development of fairness-aware information retrieval studies. Hence, a practical, scalable, low-cost group membership annotation method is needed to assist or replace human annotations. This study explored how to leverage language models to automatically annotate group membership for group fairness evaluations, focusing on annotation accuracy and its impact. Our experimental results show that BERT-based models outperformed state-of-the-art large language models, including GPT and Mistral, achieving promising annotation accuracy with minimal supervision in recent fair-ranking datasets. Our impact-oriented evaluations reveal that minimal annotation error will not degrade the effectiveness and robustness of group fairness evaluation. The proposed annotation method reduces tremendous human efforts and expands the frontier of fairness-aware studies to more datasets.

description: Strong light-matter interactions as realized in an optical cavity provide a tantalizing opportunity to control the properties of condensed matter systems. Inspired by experimental advances in cavity quantum electrodynamics and the fabrication and control of two-dimensional magnets, we investigate the fate of a quantum critical antiferromagnet coupled to an optical cavity field. Using unbiased quantum Monte Carlo simulations, we compute the scaling behavior of the magnetic structure factor and other observables. While the position and universality class are not changed by a single cavity mode, the critical fluctuations themselves obtain a sizable enhancement, scaling with a fractional exponent that defies expectations based on simple perturbation theory. The scaling exponent can be understood using a generic scaling argument, based on which we predict that the effect may be even stronger in other universality classes. Our microscopic model is based on realistic parameters for two-dimensional magnetic quantum materials and the effect may be within the range of experimental detection.

description: We show the laser-driven acceleration of unprecedented, collimated ($ 2 \ \mathrm{mrad} $ divergence), and quasi-monoenergetic ($ 25 \ \% $ energy spread) electron beams with energy up to $ 50 \ \mathrm{MeV} $ at $ 1 \ \mathrm{kHz} $ repetition rate. The laser driver is a multi-cycle ($ 15 \ \mathrm{fs} $) $ 1 \ \mathrm{kHz} $ optical parametric chirped pulse amplification (OPCPA) system, operating at $ 26 \ \mathrm{mJ} $ ($ 1.7 \ \mathrm{TW} $). The scalability of the driver laser technology and the electron beams reported in this work pave the way towards developing high-brilliance x-ray sources for medical imaging, innovative devices for brain cancer treatment, and represent a step towards the realization of a kHz GeV electron beamline.

description: Proofs of localization for random Schrödinger operators with sufficiently regular distribution of the potential can take advantage of the fractional moment method introduced by Aizenman-Molchanov, or use the classical Wegner estimate as part of another method, e.g. the multi-scale analysis introduced by Fröhlich-Spencer and significantly developed by Klein and his collaborators. When the potential distribution is singular, most proofs rely crucially on exponential estimates of events corresponding to finite truncations of the operator in question; these estimates in some sense substitute for the classical Wegner estimate. We introduce a method to "lift" such estimates, which have been obtained for many stationary models, to certain closely related non-stationary models. As an application, we use this method to derive Anderson localization on the 1-D lattice for certain non-stationary potentials along the lines of the non-perturbative approach developed by Jitomirskaya-Zhu in 2019.

description: Cette campagne, inscrite dans la continuité des travaux initiés lors de MALIS 1&2, s'intitule donc de fait MALIS 3 pour « Management of Atolls using ALIS 3 ».Deux sites étaient prioritaires pour cette campagne : Apataki et Takaroa. Apataki est un nouveau site pour la science, prioritaires en termes d'aquaculture et perliculture. T Takaroa est un site déjà étudié par plusieurs projets notamment en 2008-2012 (projet FED), mais un bloom particulièrement long à engendré de fortes mortalités des populations benthiques en 2014 (Rodier et al. 2019) et la reprise du lagon est étudiée et modélisée depuis 2019.Les objectifs de la campagne MALIS 3 sont de : Collecter les données physiques  du lagon de Apataki.  Les mesures incluent des stations fixes (ADCP et capteurs T/P), ainsi que des mesures lagrangiennes de bouées dérivantes suivies par GPS. Mesures hydrobiologiques sur des réseaux intra-lagon (chl a, sels nutritifs, production, et CTD). Réaliser des cycles CTD à haute fréquence afin d'observer la variabilité journalière de la colonne d'eau en face de la passe (Température, Salinité, Irradiance, Fluorescence, Turbidité). Ce type de données a été acquise sur 2 cycles de 36h pendant MALIS 2 sur Raroia (bathysonde toutes les 30 min), et fournit des informations importantes sur le jet entrant dans l'atoll (en cours de valorisation). Faire l'inventaire et cartographier le stock d'huitres sauvages en plongée autonome (Apataki, Takaroa). Cartographier la pente externe océanique et les passes de plusieurs atolls d'intérêt (Apataki, Takaroa, etc) au sondeur multi-faisceaux.

description: Over the past few decades, machine learning models have been extremely successful. As a result of axiomatic attribution methods, feature contributions have been explained more clearly and rigorously. There are, however, few studies that have examined domain knowledge in conjunction with the axioms. In this study, we examine asset pricing in finance, a field closely related to risk management. Consequently, when applying machine learning models, we must ensure that the attribution methods reflect the underlying risks accurately. In this work, we present and study several axioms derived from asset pricing domain knowledge. It is shown that while Shapley value and Integrated Gradients preserve most axioms, neither can satisfy all axioms. Using extensive analytical and empirical examples, we demonstrate how attribution methods can reflect risks and when they should not be used.

description: La campagne MALISAR avait pour but de réaliser une étude des marges française et italienne du Bassin Ligure afin d'analyser conjointement les problèmes de tectonique active, d'instabilités gravitaires et de transferts sédimentaires afin de mettre en évidence leurs interactions pour mieux déterminer les aléas gravitaire et sismique. Cette région, fortement urbanisée, est en effet régulièrement soumise à une activité sismique non négligeable révélée par une dizaine de forts séismes historiques (1564, 1644, 1818, 1887) et récents (1963, 1981, 1985, 1989, 1995, 2001). Cette activité sismique récurrente, associée à de forts apports sédimentaires par les fleuves Var, le Paillon et la Roya, participe à la déstabilisation régulière des sédiments de la pente continentale. Ces glissements auraient une fréquence de retour >100 ans et sont générateurs potentiels de tsunamis. L'événement du 16 octobre 1979, au long de la pente niçoise, a ainsi provoqué des dégâts matériels et des pertes humaines. Pour atteindre ces objectifs, une étude régionale a été réalisée grâce à un levé bathymétrique/imagerie acoustique par sondeur multifaisceaux EM300 associé à des données de sismique rapide (24 traces), de sismique HR (72 traces), et de sondeur de sédiment Chirp. Les projets de rattachement sont : GDR Marges, GIS Curare, ACI "aléas et changements globaux", ANR "Quantitative Seismic Hazard Assessment".
