description: Stability, electroweak symmetry breaking, and the stationarity equations of the general three-Higgs-doublet model (3HDM) where all doublets carry the same hypercharge are discussed in detail. Employing the bilinear formalism the study of the 3HDM potential turns out to be straightforward. For the case that the potential leads to the physically relevant electroweak symmetry breaking we present explicit formulae for the masses of the physical Higgs bosons.

description: Cloud storage services like Amazon S3 have become increasingly popular over the past decade, providing customers with flexible and scalable on-demand storage. However, concerns around vendor lock-in, lack of full control, and cost at scale have led to the emergence of decentralized storage models like Filecoin and IPFS. This research compares the performance and economic tradeoffs between centralized cloud and decentralized blockchain-based storage to evaluate the benefits and limitations of each approach. The analysis implements pricing functions based on cloud provider SLAs to account for factors like usage costs, service credits, and uptime guarantees. It also considers decentralized storage qualities like permissionless access, verifiable audits, and transparent incentives structures facilitated by blockchain. Experiments on AWS show centralized clouds currently outperform on latency while decentralized networks offer stronger resilience and fault tolerance. Ultimately, both models have advantages – clouds excel at convenience and speed while decentralization promotes openness and control. The findings provide storage customers a framework to assess which approach best fits their needs based on access patterns, scale, and cost requirements. This research aims to give unbiased technical guidance on adopting the optimal storage architecture.

Year: 2023

description: The ﬁeld of instant (real-time) payment systems has witnessed signiﬁcant advancements worldwide, with several countries successfully implementing real-time solutions to cater to the demands of modern ﬁnancial transactions. To adopt this transformative ﬁeld, the United States Federal Reserve has launched FedNow, a real-time payment system, to take a proactive approach to enhancing the nation’s payment infrastructure. Despite the growing importance of real-time payment systems, there is currently limited understanding of the intricacies and potential implications speciﬁc to FedNow, since previous research on instant payment systems has often focused on private-sector solutions or established instant payment systems implemented by other countries. To address these gaps in knowledge, this research explores the operational dynamics and unique features of FedNow. By conducting a comprehensive review and analysis of existing literature, academic papers, oﬃcial reports, and online resources on FedNow, this research sheds light on the signiﬁcance of FedNow. This study presents detailed insights into the key features, aspects, working mechanisms, and practical applications of the FedNow service. It also emphasizes FedNow's distinct position concerning private-sector fast payment solutions and private non-instant payment networks through a comparative analysis. The presented ﬁndings provide valuable insights for policymakers, ﬁnancial institutions, and businesses to optimize their payment strategies. The paper further aims to examine FedNow's performance by comparing it with established real-time payment systems in other countries to optimize its impact on the ﬁnancial ecosystem.

description: We report the detection of far-infrared (FIR) CO rotational emission from nearby active galactic nuclei (AGN) and starburst galaxies, as well as several merging systems and Ultra-Luminous Infrared Galaxies (ULIRGs). Using Herschel-PACS, we have detected transitions in the J$_{upp}$ = 14 - 20 range ($λ\sim$ 130 - 185 $μ$m, $ν\sim$ 1612 - 2300 GHz) with upper limits on (and in two cases, detections of) CO line fluxes up to J$_{upp}$ = 30. The PACS CO data obtained here provide the first well-sampled FIR extragalactic CO SLEDs for this range, and will be an essential reference for future high redshift studies. We find a large range in the overall SLED shape, even amongst galaxies of similar type, demonstrating the uncertainties in relying solely on high-J CO diagnostics to characterize the excitation source of a galaxy. Combining our data with low-J line intensities taken from the literature, we present a CO ratio-ratio diagram and discuss its potential diagnostic value in distinguishing excitation sources and physical properties of the molecular gas. The position of a galaxy on such a diagram is less a signature of its excitation mechanism, than an indicator of the presence (or absence) of warm, dense molecular gas. We then quantitatively analyze the CO emission from a subset of the detected sources with Large Velocity Gradient (LVG) radiative transfer models to fit the CO SLEDs. Using both single-component and two-component LVG models to fit the kinetic temperature, velocity gradient, number density and column density of the gas, we derive the molecular gas mass and the corresponding CO-to-H$_2$ conversion factor, $α_{CO}$, for each respective source. For the ULIRGs we find $α$ values in the canonical range 0.4 - 5 M$_\odot$/(K kms$^{-1}$pc$^2$), while for the other objects, $α$ varies between 0.2 and 14.} Finally, we compare our best-fit LVG model ..

Year: 2023

description: In the rapidly evolving field of cryptocurrency mining, a process heavily reliant on heavy energy consumption from mining rigs, profitability is influenced by a myriad of factors. One such factor is the quality and sophistication of mining equipment. While advanced equipment can enhance mining efficiency, this advantage must be weighed against the substantial capital investments required for equipment upgrades as well as the costs of power consumption. Past research has generally focused on the impact of different sources of energy on activity levels of miners. This study aims to explore the trade-off between the use of advanced mining equipment and cost-saving measures. Drawing on a detailed analysis of annual SEC filings from 11 publicly traded Bitcoin mining companies with mining operations in North America, there exists a potential positive relationship between procurement of state-of-the-art mining equipment and a company’s financial performance. However, as technology constantly improves, maintaining up-to-date, high-quality mining equipment is a significant challenge for companies, requiring substantial capital investments. Global shortages of key components can cause mining equipment to become scarce, allowing for the possibility of companies to obtain a comparative advantage by receiving access to such equipment. The findings reveal that strategic equipment management and allocation of power resources for the equipment play a critical role in maximizing profitability in the cryptocurrency mining industry.

description: GitHub, a service for software development, hosts millions of projects. However, some repositories are lacking, while others excel. Our study aims to uncover the characteristics that contribute to a project’s success. Using GitHub Archive, a project that records the public GitHub timeline and archives it, our study tests four different hypotheses against the product quality of the open-source software on GitHub and available on GitHub Archive. Our study primarily focuses on Ethereum, a decentralized blockchain. Product quality and success was measured through two different features. The first is the number of forks, as developers tend to fork repositories when they are interested. The second is through the number of watches. By watching a repository, you are notified by changes in the repository—a direct measure of popularity. Using econometric modeling to confirm our results, our hypotheses test the different roles core developers and peripheral developers play when contributing to the success of a project, the importance of developer related collaboration, the relationship between project structure and popularity, and the importance of a project among other open-source software. Testing these four hypotheses, and measuring the statistical significance of each variable, will determine the characteristics that contribute to the success of a project on GitHub.

Year: 2025
Subjects: classificationCode: 460401
subject: Cryptography

description: This paper examines various significant symmetric and asymmetric cryptography algorithms and their importance in network security. With the increasing use of the internet, there has been a corresponding rise in attacks on communication channels. Such attacks may enable third parties to access sensitive information regarding an organization and its operations. This information could potentially be used to disrupt an organization's activities or to extort payment in exchange for the data. To mitigate these risks, cryptographic algorithms are employed to secure communications. These algorithms encrypt data in a manner that makes it difficult for unauthorized individuals to access, rendering it ineffective for attackers. Consequently, these algorithms are essential to the security of communications. This paper presents a study of symmetric and asymmetric algorithms with respect to optimal resource allocation, potential attacks that may exploit these algorithms, time and power consumption, overall structure, and other relevant factors, along with an explanation of various security attacks.
LiDAR Drone Technology in Law Enforcement Yields Most Accurate Measurements at an Altitude of 60 Feet

description: In law enforcement, LiDAR technology is used to document and investigate crime scenes. By attaching a LiDAR sensor to a drone, scientists make this method of documentation more accessible and accurate with a quick response time in the field. Drones have become increasingly useful in law enforcement with technology such as photogrammetry, thermal infrared sensors, and most recently, LiDAR sensors. This field is yet to determine the accuracy with capturing LiDAR data with differing drone heights and mapping settings. Flight altitudes affect the point cloud density where lower altitudes yield dense point clouds and more sharp, accurate images (Njambi, 2021). For this experiment, an object with a horizontal length of 0.35 meters and vertical distance of 0.09 meters was placed in a grassy area. Measurements were taken with both single and triple return by a drone LiDAR system with altitudes of 60ft, 100ft, 125ft, and 150ft. The object was detected in all flights with most detailed LiDAR imagery using triple return. Object measurements ranged from a horizontal length of 0.21 meters to 0.38 meters with the differing parameters. Vertical heights measured were not consistent with the object’s vertical height in any flight. Flight parameters of 60 feet triple return with 80% forward and side overlap yielded most accurate measurements of the object with a horizontal length of 0.36 meters.

description: We propose a mechanism for sufficient suppression of dimension-5 operators for proton decay in a supersymmetric SO(10) model. This mechanism is analogue to the double seesaw mechanism in studying neutrino masses. Only an intermediate VEV instead of an intermediate scale is required so that gauge coupling unification is maintained. The VEV is generated by introducing an anomalous U(1) symmetry whose breaking is at higher scale. The proton decay amplitudes are suppressed by this VEV over the GUT scale. We use $\textbf{45+54}$ in breaking GUT symmetry. $\textbf{120}$ is included so that fermion sector is fully realistic. Assuming a minimal fine-tuning in the Higgs doublet sector, $\textrm{tan}β$ of order one is predicted.

description: Das Thema der Masterarbeit sind die Aufgabenstellungen in vier verschiedenen Biologieschulbüchern der Sekundarstufe I und die Frage danach, ob diese grundsätzlich in einem sprachbewussten und kompetenzorientierten Fachunterricht unterstützend eingesetzt werden können. Dafür wurde eine quantitative Analyse der Aufgabenstellungen anhand zuvor definierter Kategorien vorgenommen und mittels deskriptiver Statistik ausgewertet, um zu sehen, inwiefern die Vorgaben aus der Handreichung des BMBWF sowie der Lehrpläne umgesetzt wurden. Die verwendeten Kategorien befassen sich mit der Formulierung der Operatoren sowie den geförderten Handlungskompetenzen, da diese Eckpfeiler des kompetenzorientierten sowie sprachbewussten Fachunterrichtes sind. Die analysierten Bücher sind: bio@school 1 (Schermaier & Weisl 2020), Bio Logisch 2 (Gereben-Krenn, Jaenicke & Jungbauer 2017), einfach bio 2 (Gazzia & Stoll 2017) sowie Begegnungen mit der Natur 3 (Biegl 2019). Die Ergebnisse weisen darauf hin, dass sowohl die Operatoren als auch die Handlungskompetenzen größtenteils laut den Vorgaben eingesetzt und gefördert werden. Trotzdem sind manche Aufgaben als Fragestellung formuliert, sowohl explizit als Fragesatz als auch versteckt durch eine Operator-Fragewort-Kombination. Bezüglich der Handlungskompetenzen dominiert der Bereich Erkenntnisse gewinnen (W), tendenziell werden mit steigender Jahrgangsstufe zunehmend komplexere kognitive Prozesse sowie Handlungskompetenzen gefördert. Bezüglich beider Fragestellungen konnten Unterschiede zwischen den Schulbüchern aufgezeigt werden. Interessant ist zudem, dass häufig verschiedene Kategorien miteinander kombiniert in einer Aufgabenstellung auftreten. Insgesamt lässt sich feststellen, dass die Aufgabenstellungen aus den analysierten Schulbüchern in einem sprachbewussten Fachunterricht unterstützend eingesetzt werden können. Trotzdem müssen sich die Lehrkräfte konkret mit den damit einhergehenden sprachlichen Mitteln und Herausforderungen auseinandersetzen, da die Aufgabenstellungen aus den Schulbüchern kein hinreichendes Merkmal für einen sprachbewussten Fachunterricht darstellen.

description: A tool of managing personal studios is important and useful for private lesson teachers, such as piano teachers, violin teachers, personal training coaches/tutors, etc. Such a management tool can reduce the teachers' time significantly in scheduling classes, keep a clear picture of students/trainees' progress, make the communications between the teachers and the students efficiently and quickly, and provide insightful feedback on the past experience to help the teachers make plans. The product we are going to develop is a software tool, working as a web applications and an app on smart phones. This tool helps private lesson teachers to manage their studios in a time-efficient manner and to get analytical results on the performance of the studios. We are going to build a product with advanced scheduling algorithms and machine learning algorithms to help private lesson teachers improve class management efficiency and make decisions based on insightful, analytical performance. We apply machine learning algorithms to provide insightful feedback to the teachers and the students. At the current moment, we provide auto-classification on piano pieces. We are currently working on the performance analysis of these algorithms, theoretically and empirically.

Pour ce projet, 3 hydrophones autonomes ont été immergés dans le canal SOFAR pendant 14 mois entre les îles de La Réunion, Kerguelen et Amsterdam.  Leur déploiement a été effectué lors de la campagne MD157 (oct 2006). Leur récupération a été réalisée lors de deux missions en janvier 2008 (MD165-VT95) et avril 2008 (OP2008/1). Le dispositif proposé a été configuré pour une surveillance acoustique continue de l'activité sismique de 3 dorsales à taux d'ouverture contrastés (16 à 70 mm/a) et de la déformation intraplaque du sud du bassin Indien Central.  L'approche est particulièrement performante pour détecter et localiser la sismicité de faible magnitude (>2.5) qui échappe aux réseaux sismologiques terrestres et distinguer les évènements d'origine tectonique ou magmatique.  Les objectifs sont de caractériser le fonctionnement spatio-temporelle de 3 dorsales ultra-lente, lente et intermédiaire, de préciser la distribution spatio-temporelle des déformations intraplaques, et de vérifier la présence de précurseurs de faible magnitude avant les séismes majeurs sur les failles actives sous-marines.Cet observatoire sera également utilisé pour détecter l'activité acoustique des mammifères marins en particulier les grandes baleines.Le projet de rattachement est DEFLO-HYDRO.
The jumping coefficients of non-Q-Gorenstein multiplier ideals

Subjects: subject: Algebraic Geometry (math.AG)

description: Let $\mathfrak a \subset \mathscr O_X$ be a coherent ideal sheaf on a normal complex variety $X$, and let $c \ge 0$ be a real number. De Fernex and Hacon associated a multiplier ideal sheaf to the pair $(X, \mathfrak a^c)$ which coincides with the usual notion whenever the canonical divisor $K_X$ is $\mathbb Q$-Cartier. We investigate the properties of the jumping numbers associated to these multiplier ideals. We show that the set of jumping numbers of a pair is unbounded, countable and satisfies a certain periodicity property. We then prove that the jumping numbers form a discrete set of real numbers if the locus where $K_X$ fails to be $\mathbb Q$-Cartier is zero-dimensional. It follows that discreteness holds whenever $X$ is a threefold with rational singularities. Furthermore, we show that the jumping numbers are rational and discrete if one removes from $X$ a closed subset $W \subset X$ of codimension at least three, which does not depend on $\mathfrak a$. We also obtain that outside of $W$, the multiplier ideal reduces to the test ideal modulo sufficiently large primes $p \gg 0$.

description: It has been demonstrated numerically, mainly by considering ground state properties, that fractional quantum Hall physics can appear in lattice systems, but it is very difficult to study the anyons directly. Here, I propose to solve this problem by using conformal field theory to build semi-analytical fractional quantum Hall lattice models having anyons in their ground states, and I carry out the construction explicitly for the family of bosonic and fermionic Laughlin states. This enables me to show directly that the braiding properties of the anyons are those expected from analytical continuation of the wave functions and to compute properties such as internal structure, size, and charge of the anyons with simple Monte Carlo simulations. The models can also be used to study how the anyons behave when they approach or even pass through the edge of the sample. Finally, I compute the effective magnetic field seen by the anyons, which varies periodically due to the presence of the lattice.

title: Sex dependent differences in biceps brachii muscle size, overlying subcutaneous fat thickness and corticospinal excitability
Creators: name: Olarogba, Olalekan B.
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: Indirect measurement of subcutaneous fat thickness using skinfold measurement has been used as the most common method of investigating fat thickness in humans. Likewise, studies that have reported on the muscle size mostly involved cadaver studies. From this research, muscle size and subcutaneous fat thickness were measured using B-mode ultrasound and the effect of these factors on corticospinal excitability were determined. Many studies have investigated the role of the corticospinal tract in the development of voluntary force. However, the effect of muscle size and fat thickness on corticospinal excitability has not been examined. The current study was designed to assess corticospinal excitability of the biceps brachii using a transcranial magnetic stimulation (TMS) protocol and assess muscle and fat thickness via B-mode ultrasound to determine the impact of muscle and fat thickness has on corticospinal excitability and whether or not this impact was sex-dependent. The maximum stimulator output required to achieved active motor threshold was higher in female than male. Motor evoked potential (MEP) amplitudes from the biceps increased significantly (p < .001) and similarly (p = .365) for both men and women. For men there was a significant (p < .05, r = 0.591) positive relationship between muscle size and MEP amplitude, whereas for women there was a significant (p < .05, r = -0.525) negative relationship between MEP amplitude and skinfold thickness. Collectively, the data suggest that the amount of muscle size and subcutaneous fat thickness affects CSE, and these findings are sex- dependent.

description: In this paper we present results of ab-initio calculations for the beryllium dimer with basis set of Slater-type orbitals (STOs). Nonrelativistic interaction energy of the system is determined using the frozen-core full configuration interaction calculations combined with high-level coupled cluster correction for inner-shell effects. Newly developed STOs basis sets, ranging in quality from double to sextuple zeta, are used in these computations. Principles of their construction are discussed and several atomic benchmarks are presented. Relativistic effects of order $α^2$ are calculated perturbatively by using the Breit-Pauli Hamiltonian and are found to be significant. We also estimate the leading-order QED effects. Influence of the adiabatic correction is found to be negligible. Finally, the interaction energy of the beryllium dimer is determined to be 929.0$\,\pm\,$1.9 $cm^{-1}$, in a very good agreement with the recent experimental value. The results presented here appear to be the most accurate ab-initio calculations for the beryllium dimer available in the literature up to date and probably also one of the most accurate calculations for molecular systems containing more than four electrons.

description: Word retrieval difficulty (lexical access deficit) is prevalent in aphasia. Studies have shown that practice retrieving names from long-term memory (retrieval practice) improves future name retrieval for production in people with aphasia (PWA), particularly when retrieval is effortful. To explicate such effects, this study examined a potential role for semantic competition in the learning mechanism(s) underlying effortful retrieval practice effects in lexical access in 6 PWA. Items were trained in a blocked-cyclic naming task, in which repeating sets of pictures drawn from semantically-related versus unrelated categories underwent retrieval practice with feedback. Naming accuracy was lower for the related items at training, but next-day accuracy did not differ between the conditions. However, greater semantic-relatedness of an item to its set in the related condition was associated with lower accuracy at training but higher accuracy at test. Relevance to theories of lexical access and implications for naming treatment in aphasia are discussed.

description: Economists widely agree that a country’s financial system plays an important role in its economic development and – if well established – can provide considerable benefits to society. Yet, we still know relatively little about those who work in the financial industry. Why do people decide to pursue a career in finance? How do finance professionals differ from other people in terms of their norms and values? And what determines their behavior?
 This thesis is aimed at broadening our understanding of who are the social animals that work in the U.S. financial industry. The three studies that comprise this thesis contribute to the emerging field of social finance by expanding our knowledge of the social factors that influence finance professionals and determine their economic behavior.
 The first study begins at the making of finance professionals. It provides evidence that people are substantially more likely to choose a career in finance if their fathers have already worked in the financial industry. This intergenerational correlation between fathers and their children is greater than in most other industries and is related to a considerable income surplus of second-generation finance industry employees.
 The second study documents a unique and worrisome deterioration in generalized trust, an important social belief, among finance industry employees over the past decades. This decline in trust is also significantly stronger than the trust decline among the general U.S. population over the same period. It appears to be associated with changes in the economic conditions in the U.S., shifts in the professional environment in the financial industry, and with a decreasing degree of socialization among finance professionals.
 The third study reveals a long-lasting association between the disruption of the family of origin during the childhood of mutual fund managers and their investment behavior later in life. Fund managers who experienced the death or divorce of their parents early in life exhibit a stronger disposition effect and take less risk in their delegated portfolios. This study hence promotes our understanding of the long-term impact of traumatic childhood experiences and the origins of investment biases.

description: We introduce an integrability-based method enabling the study of semiconductor quantum dot models incorporating both the full hyperfine interaction as well as a mean-field treatment of dipole-dipole interactions in the nuclear spin bath. By performing free induction decay and spin echo simulations we characterize the combined effect of both types of interactions on the decoherence of the electron spin, for external fields ranging from low to high values. We show that for spin echo simulations the hyperfine interaction is the dominant source of decoherence at short times for low fields, and competes with the dipole-dipole interactions at longer times. On the contrary, at high fields the main source of decay is due to the dipole-dipole interactions. In the latter regime an asymmetry in the echo is observed. Furthermore, the non-decaying fraction previously observed for zero field free induction decay simulations in quantum dots with only hyperfine interactions, is destroyed for longer times by the mean-field treatment of the dipolar interactions.

description: While generative accounts of language processing assume that children break down language into smaller components on which they apply computational operations, usage-based accounts assume that children acquire frequently co-occurring words as large chunks, which they decompose only later in development. We investigated the evidence for the multi-word representation of idioms like to let the cat out of the bag in 9- to 10-year-olds using eye-tracking and Event-Related Potentials. Both measures indicated that children rapidly predict idiom-final words (bag). However, although they are generally capable of rapidly predicting semantic associates for highly predictive endings of novel sentences (as demonstrated in a control experiment), within idioms they activate semantic associates (basket) only in a late processing stage. We conclude that children rapidly activate multi-word units for idioms and decompose these units only after a short delay during online processing. This effect might relate to unitary acquisition of idioms as assumed by usage-based accounts.

description: Large language models (LLMs), such as ChatGPT, are by nature “bullshit” generators, as they are not recognizant of “truths.” As per Frankfurt’s theory, bullshit is defined as utterances made without acknowledgment of the truth. LLMs generate responses by predicting the next most probable word in a sequence without recognition of the truth. As ChatGPT peaks in the hype cycle as of early 2023, there have been many media contents that cover ChatGPT and similar LLMs. At best, these media contents can be beneficial in helping people understand the technology; but at worse, they could facilitate the generation of bullshit on the Internet, which is already filled with human-generated misinformation. This makes it necessary to understand how much the media contents have potential risk (or provide opportunities) to the media environment on the Internet. To understand the use of ChatGTP and their potential risk of bullshit generation, we analyzed YouTube videos that have been published since the introduction of ChatGTP in December 2023. Among the entire videos collected from YouTube APIs using keywords, “ChatGPT, GPT-3.5, and GPT-4,” we randomly sampled about 400 Youtube videos and analyzed their potential risk of bullshit, manually categorizing videos as low risk, high risk, reducing risk, or bullshit itself. A majority of high-risk videos were about how to make money through automatically generating media content, whereas experimental videos that tested ChatGPT’s capabilities tended to reduce the risk of bullshit by explaining the shortfalls of ChatGPT. In addition, sentiment analysis of the videos’ comments, ANOVA, and Fisher’s exact test were conducted to examine the relationships between video features, type of bullshit risk, and video performance. Results show that high-risk YouTube videos may be incentivized more in spreading bullshit, as they promote monetary success using ChatGPT. Also, based on the baseline understanding of YouTube videos, we developed a machine learning model that can predict videos’ bullshit risks by leveraging channel statistics such as the number of views, likes, comments, and subscribers. Our study provides an implication for social media designers that, as there is a high potential of AI-generated content to spread bullshit, there is a need to develop more effective content moderation strategies.

description: : Leukotriene A4 hydrolase (LTA4H) is a bi-functional enzyme that promotes a pro-inflammatory epoxy hydrolase (EH) pathway and an anti-inflammatory aminopeptidase (AP) pathway. LTA4H EH activity catalyzes the hydrolysis of leukotriene A4 (LTA4) to the neutrophil chemoattractant leukotriene B4 (LTB4), while AP activity hydrolyzes the tripeptide proline-glycine-proline (PGP) to clear neutrophils in the lungs. Previously published studies focused on blocking EH activity to inhibit the LTB4 formation with small molecule inhibitors. Our research focuses on the activation of LTA4H AP activity in the presence of small molecule activators. Prior to kinetic analysis, a standard curve was obtained using para-nitroanilide (pNA) at escalating concentrations. A chromogenic substrate alanine-p-nitroanilide (Ala-pNA) was used to measure the AP activity of LTA4H. Using the 4-methoxydiphenylmethane (4MDM) as a positive control for activating the AP activity and bestatin as a negative control for inhibiting AP activity, the modulation of LTA4H AP activity was analyzed in the presence of compounds B08-2a and B08-2b through the determination of a 50% activation or inhibition (AC50/IC50) kinetic assay. In conclusion, our research involves the high-throughput assay for screening small molecules to modulate the AP activity of LTA4H. The discovery of small molecules that activate the AP activity of the LTA4H enzyme is a potential new therapeutic agent for lung inflammatory diseases, such as chronic obstructive pulmonary disease (COPD).

Etat chimique des sédiments et influence d'une extraction de granulats sur l'état chimique de l'eau de mer dans le cadre du PER GMH - Etude SCOOTER. Etude sur la remobilisation de Sédiments potentiellement COntaminés induite par une OpéraTion d’ExtRaction de granulats en baie de Seine

description: Dans les mers côtières où les données des réseaux de surveillance montrent que les sédiments fins en surface contiennent des contaminants, la remobilisation de ces matériaux à l’occasion d’extractions de granulats, qui génère un panache turbide, pourrait influencer la qualité de l’eau. La baie de Seine orientale est sous l’influence du panache de la Seine, l’un des fleuves les plus contaminés d’Europe.
Cette étude avait pour objectif d’examiner la remobilisation des métaux traces et de contaminants organiques des sédiments vers la surface pendant et après une extraction de granulats à travers leur comportement entre la fraction totale et dissoute. Pour cela, l’expérimentation a été réalisée lors d’un essai d’extraction dans le cadre du Permis Exclusif de Recherche des Granulats Marins Havrais (PER GMH) obtenus par les entreprises Les Graves de l’Estuaire et Matériaux Baie de Seine entre mi-2010 et mi-2015 (ouverture de travaux obtenue en 2012).
Le site de l’étude était situé à environ 20 km des côtes du Havre dans le périmètre du PER dans la Zone Ouest sélectionnée pour un essai d’extraction. Lors d’une première phase réalisée à basse mer pour être sous l’influence du panache de la Seine, une caractérisation de l’état chimique des sédiments de la zone et de l’eau de mer verticalement a été effectuée. Puis, la deuxième phase, réalisée sur la période étal de pleine mer - flot, a consisté à réaliser un état initial avant extraction, puis à prélever des échantillons d’eau de mer brute et filtrée (< 0,2 µm) en sub-surface dans le panache turbide généré par le navire extracteur à une fréquence donnée, et à effectuer un dernier prélèvement une heure après la fin de l’extraction. Les résultats ont montré une remise en suspension de métaux traces associés aux sédiments tout au long de la durée de l’extraction, avec peu de transfert dans la phase dissoute, puis une nette tendance au retour à l’état initial dans l’eau brute et l’eau filtrée pendant la disparition du panache turbide. L’essai d’extraction de granulats dans la Zone Ouest du PER GMH a donc bien eu une influence sur l’état chimique de l’eau dans le panache turbide pendant sa durée de vie, mais ne semble pas montrer d’influence à long terme (après la disparition du panache) sur la qualité globale de l’eau sur le site de l’étude.
