title: Zusammenhang zwischen Stress und dem Konsum süßer Getränke bei Jugendlichen
Creators: name: Preissler, Peter Bastian
Year: 2021

description: Hintergrund: Stress ist ein grundlegender Bestandteil des täglichen Lebens, allerdings kann starker oder chronischer Stress die Gesundheit kompromittieren und zudem das Verhalten beeinflussen. Aufbauend auf bisherigen Ergebnissen, wonach Stress in der Lage ist, die Aufnahme von energiedichten und geschmacklich besonders belohnenden Lebensmitteln zu begünstigen, sollte in dieser Arbeit der Zusammenhang zwischen der Stresswahrnehmung und dem Konsum von süßen Getränken bei Jugendlichen untersucht werden. Methodik: Zu diesem Zweck wurden Wiener SchülerInnen aus allgemeinbildenden höheren Schulen mittels Fragebogen zu ihrem Konsum von süßen Getränken, ihrer allgemeinen Stresswahrnehmung sowie weiteren Faktoren befragt, welche ebenfalls einen möglichen Einfluss auf die Aufnahme von süßen Getränken verzeichnen. Außerdem wurde nach dem wahrgenommenen Einfluss der COVID-19-Pandemie auf das allgemeine Stresslevel sowie auf den Konsum süßer Getränke gefragt. Insgesamt wurden die Ergebnisse von 430 SchülerInnen (weiblich: 52,5 %; durchschnittliches Alter: 16,3 Jahre) der 9., 10. und 11. Schulstufe inkludiert. Ergebnisse: Die durchschnittliche tägliche Aufnahmemenge süßer Getränke konnte unter den ProbandInnen mit 551 mL/Tag (SD = 598 mL/Tag) beobachtet werden, mit höheren Aufnahmemengen unter den männlichen Teilnehmern. Die Stresswahrnehmung der TeilnehmerInnen erreichte einen durchschnittlichen Score von 20,6 (SD = 7,3), wobei hier weibliche Probandinnen höhere Werte verzeichneten. Darüber hinaus konnte die globale COVID-19-Pandemie als bedeutender Stressor in der Wahrnehmung der Jugendlichen identifiziert werden. Neben dem Geschlecht und der Aufnahmehäufigkeit von ernährungsphysiologisch unvorteilhaften Lebensmitteln, erwies sich die Interaktion von Stress und gezügeltem Ernährungsverhalten als signifikanter Prädiktor der täglichen Gesamtaufnahme süßer Getränke. Ein signifikanter Haupteffekt von Stress konnte hingegen lediglich für die tägliche Aufnahmemenge von süßen Getränken ermittelt werden, wenn die Untersuchung auf ausschließlich koffeinhaltige Süßgetränke beschränkt wurde. Demnach wiesen ProbandInnen mit einer erhöhten Stresswahrnehmung im vorangegangenen Monat eine höhere tägliche Aufnahme koffeinhaltiger Süßgetränke über diesen Zeitraum auf. Schlussfolgerung: Die beobachtete positive Assoziation zwischen der Stresswahrnehmung und der Aufnahme koffeinhaltiger Süßgetränke sowie mögliche Gesundheitsauswirkungen einer langfristigen und potentiell stressbedingten Aufnahme der Inhaltsstoffe Zucker, Süßungsmittel und Koffein, welche in süßen Getränken prädominant vertreten sind, machen die Notwendigkeit einer effektiven Stressbewältigung unter jugendlichen SchülerInnen, besonders in Zeiten der globalen COVID-19-Pandemie, deutlich. Dabei könnten vor allem Jugendliche mit einem gezügelten Ernährungsverhalten von einer Stressreduktion profitieren.

description: A ring-kinetic theory for Vicsek-style models of self-propelled agents is derived from the exact N-particle evolution equation in phase space. The theory goes beyond mean-field and does not rely on Boltzmann's approximation of molecular chaos. It can handle pre-collisional correlations and cluster formation which both seem important to understand the phase transition to collective motion. We propose a diagrammatic technique to perform a small density expansion of the collision operator and derive the first two equations of the BBGKY-hierarchy. An algorithm is presented that numerically solves the evolution equation for the two-particle correlations on a lattice. Agent-based simulations are performed and informative quantities such as orientational and density correlation functions are compared with those obtained by ring-kinetic theory. Excellent quantitative agreement between simulations and theory is found at not too small noises and mean free paths. This shows that there is parameter ranges in Vicsek-like models where the correlated closure of the BBGKY-hierarchy gives correct and nontrivial results. We calculate the dependence of the orientational correlations on distance in the disordered phase and find that it seems to be consistent with a power law with exponent around -1.8, followed by an exponential decay. General limitations of the kinetic theory and its numerical solution are discussed.

description: The efficiencies/coefficients of performance of three-terminal devices, comprising two electronic terminals and a thermal one (e.g., a boson bath) are discussed. In particular, two procedures are analyzed. (a) One of the electronic terminals is cooled by investing thermal power (from the thermal bath) and electric power (from voltage applied across the electronic junction); (b) The invested thermal power from the boson bath is exploited to cool one electronic terminal and to produce electric power. Rather surprisingly, the coefficient of performance of (b) can be enhanced as compared to that of (a).

title: Χαρακτηριστικές μεταλλευτικές και μεταλλουργικές καινοτομίες κατά την Αναγέννηση, με έμφαση στην συμβολή του Agricola

description: Η παρούσα διπλωματική εργασία παρουσιάζει την εξελικτική πορεία της μεταλλευτικής και της μεταλλουργίας κατά τη διάρκεια της Αναγέννησης, με ιδιαίτερη έμφαση στον «Πατέρα της μεταλλευτικής και της ορυκτολογίας» Georgius Agricola και στον καθοριστικό ρόλο του στην ανάδειξη και καθιέρωσή τους σε επιστημονικό επίπεδο. Όσες αναφορές υπάρχουν στην ελληνική βιβλιογραφία έως σήμερα στο έργο και στη συμβολή του, είναι αποσπασματικές και σχετικά επιφανειακές. Στόχος της παρούσας εργασίας είναι να αναδείξει κάποιες από τις πιο σημαντικές πτυχές του έργου του, οι οποίες θεωρούνται καινοτόμες για την εποχή τους.
Μέχρι την εποχή του Agricola, το έργο του Πλίνιου του Πρεσβύτερου «Historia Naturalis» ήταν η κύρια πηγή πληροφοριών για τα μέταλλα και τις τεχνικές εξόρυξής τους. Ο Agricola αναγνώρισε το χρέος που όφειλε σε αρχαίους συγγραφείς, όπως ο Πλίνιος και ο Θεόφραστος και έκανε πολλές αναφορές στα έργα αυτά. O ίδιος όμως ήταν επίσης αυτός που επεξήγησε πώς εμφανίζονται οι φλέβες μεταλλευμάτων μέσα και πάνω στο έδαφος. Περιέγραψε την αναζήτηση φλεβών και την λεπτομερή αποτύπωση, καθώς και την έκπλυση των μεταλλευμάτων για τη συλλογή των βαρύτερων πολύτιμων μεταλλικών στοιχείων, όπως ο χρυσός και ο κασσίτερος.
Το έργο του είναι μια συστηματική, εικονογραφημένη πραγματεία για την μεταλλευτική και την μεταλλουργία. Περιγράφει διαδικασίες εξόρυξης μεταλλευμάτων από το έδαφος και διαχωρισμού των μετάλλων από το μετάλλευμα. Ήταν πράγματι από τους πρώτους που χρησιμοποίησε τον παραγωγικό συλλογισμό παρά την αυθεντία ορισμένων μελετητών και την παρατήρηση σε αντίθεση με την εικασία, θέτοντας με τον τρόπο αυτό τις βάσεις για τη Γεωλογία ως επιστήμη.
Το «De Re Metallica» (Περί της φύσης των μετάλλων) - 1556 είναι το πιο γνωστό έργο του Agricola και αποτελεί ορόσημο καθώς θεωρείται θεμελιώδες για την Μεταλλευτική και τις Γεωεπιστήμες. Το έργο δημιουργήθηκε σε μια εποχή η οποία χαρακτηρίστηκε από ιστορικές αλλαγές στη θρησκευτική σκέψη, καθώς και στο κοινωνικό και οικονομικό περιβάλλον.
Για περίπου δύο αιώνες το έργο του αποτέλεσε το βασικό εγχειρίδιο και οδηγό για τους μεταλλωρύχους και τους μεταλλουργούς. Αξίζει, επίσης να σημειωθεί ότι το «De Re Metallica» εκδόθηκε δέκα φορές σε τρεις γλώσσες, σε μια εποχή όπου η εκτύπωση τέτοιου όγκου δεν ήταν συνηθισμένο εγχείρημα.

description: The identification and restoration of ancient watermarks have long been a major topic in codicology and history. Classifying historical documents based on watermarks is challenging due to their diversity, noisy samples, multiple representation modes, and minor distinctions between classes and intra-class variations. This paper proposes a modified U-net-based conditional generative adversarial network (GAN) named Npix2Cpix to translate noisy raw historical watermarked images into clean, handwriting-free watermarked images by performing image translation from degraded (noisy) pixels to clean pixels. Using image-to-image translation and adversarial learning, the network creates clutter-free images for watermark restoration and categorization. The generator and discriminator of the proposed GAN are trained using two separate loss functions, each based on the distance between images, to learn the mapping from the input noisy image to the output clean image. After using the proposed GAN to pre-process noisy watermarked images, Siamese-based one-shot learning is employed for watermark classification. Experimental results on a large-scale historical watermark dataset demonstrate that cleaning the noisy watermarked images can help to achieve high one-shot classification accuracy. The qualitative and quantitative evaluation of the retrieved watermarked image highlights the effectiveness of the proposed approach.

description: Boyd (1974) proposed a class of infinite ball packings that are generated by inversions. Later, Maxwell (1983) interpreted Boyd's construction in terms of root systems in Lorentz space. In particular, he showed that the space-like weight vectors correspond to a ball packing if and only if the associated Coxeter graph is of "level $2$." In Maxwell's work, the simple roots form a basis of the representations space of the Coxeter group. In several recent studies, the more general based root system is considered, where the simple roots are only required to be positively independent. In this paper, we propose a geometric version of "level" for the root system to replace Maxwell's graph theoretical "level." Then we show that Maxwell's results naturally extend to the more general root systems with positively independent simple roots. In particular, the space-like extreme rays of the Tits cone correspond to a ball packing if and only if the root system is of level $2$. We also present a partial classification of level-$2$ root systems, namely the Coxeter $d$-polytopes of level-$2$ with $d+2$ facets.

description: FPGAs have distinct advantages as a technology for deploying deep neural networks (DNNs) at the edge. Lookup Table (LUT) based networks, where neurons are directly modeled using LUTs, help maximize this promise of offering ultra-low latency and high area efficiency on FPGAs. Unfortunately, LUT resource usage scales exponentially with the number of inputs to the LUT, restricting PolyLUT to small LUT sizes. This work introduces PolyLUT-Add, a technique that enhances neuron connectivity by combining $A$ PolyLUT sub-neurons via addition to improve accuracy. Moreover, we describe a novel architecture to improve its scalability. We evaluated our implementation over the MNIST, Jet Substructure classification, and Network Intrusion Detection benchmark and found that for similar accuracy, PolyLUT-Add achieves a LUT reduction of $2.0-13.9\times$ with a $1.2-1.6\times$ decrease in latency.

Out of Nowhere: The Rise of the National Jazz Tradition in Sweden, 1945-1976
Creators: name: Tenenholtz, David M.
Publisher: name: No Publisher Supplied
Year: 2007

description: The progression of post-World War II jazz in Sweden is elaborated through study of some of that country’s most uniquely influential artists. Beginning with a discussion of topics concentrating on the early reliance upon American models, the alto saxophonist Arne Domnérus and trumpeter Rolf Ericson are shown to establish a jazz practice that ushers in the careers of more nationalistic artists such as baritone saxophonist and composer Lars Gullin. The turbulent life and career of Gullin is explicated, and highlights his major compositions that launched a segment of folk-inspired jazz that earned the epithet “goatherd’s jazz.” Through musical analysis, a selection of Gullin’s works areused to show how the composer melded certain departures in songform found in Swedish folk music with the aesthetic practice of Cool Jazz of the 1950s. Other influential Swedish musicians such as Bengt-Arne Wallin, Nils Lindberg, and Jan Johansson are discussed to further broaden the nationalistic trend. The appendix features a near complete discography of pianist Johansson’s musical career, whereby Swedish jazz transcended previous American patterns and codified its own repertoire centering on regional folk songs.

description: In this paper, we consider the generalized fractional maximal function and use it to introduce the space of generalized fractional maximal functions and the various cones of monotone functions generated by generalized fractional maximal functions $M_Φf$. We introduced three function classes. We give equivalent descriptions of such cones when the function $Φ$ belongs to some function classes. The conditions for their mutual covering are given. Then, these cones are used to construct a criterion for embedding the space of generalized fractional maximal functions into the rearrangement invariant spaces (RIS). The optimal RIS for such embedding is also described.

description: Efforts to ensure reliable operation of existing low-voltage distribution systems with high photovoltaic (PV) generation have focused on the possibility of inverters providing ancillary services such as active power curtailment and reactive power compensation. Major benefits include the possibility of averting overvoltages, which may otherwise be experienced when PV generation exceeds the demand. This paper deals with ancillary service procurement in the face of solar irradiance forecasting errors. In particular, assuming that the forecasted PV irradiance can be described by a random variable with known (empirical) distribution, the proposed uncertainty-aware optimal inverter dispatch (OID) framework indicates which inverters should provide ancillary services with a guaranteed a-priori risk level of PV generation surplus. To capture forecasting errors, and strike a balance between risk of overvoltages and (re)active power reserves, the concept of conditional value-at-risk is advocated. Due to AC power balance equations and binary inverter selection variables, the formulated OID involves the solution of a nonconvex mixed-integer nonlinear program. However, a computationally-affordable convex relaxation is derived by leveraging sparsity-promoting regularization approaches and semidefinite relaxation techniques. The proposed scheme is tested using real-world PV-generation and load-profile data for an illustrative low-voltage residential distribution system.

description: Recent advancements in Self-Supervised Learning (SSL) have shown promising results in Speaker Verification (SV). However, narrowing the performance gap with supervised systems remains an ongoing challenge. Several studies have observed that speech representations from large-scale ASR models contain valuable speaker information. This work explores the limitations of fine-tuning these models for SV using an SSL contrastive objective in an end-to-end approach. Then, we propose a framework to learn speaker representations in an SSL context by fine-tuning a pre-trained WavLM with a supervised loss using pseudo-labels. Initial pseudo-labels are derived from an SSL DINO-based model and are iteratively refined by clustering the model embeddings. Our method achieves 0.99% EER on VoxCeleb1-O, establishing the new state-of-the-art on self-supervised SV. As this performance is close to our supervised baseline of 0.94% EER, this contribution is a step towards supervised performance on SV with SSL.

description: While wide-field surveys of M31 have revealed much substructure at large radii, understanding the nature and origin of this material is not straightforward from morphology alone. Using deep HST/ACS data, we have derived further constraints in the form of quantitative star formation histories (SFHs) for 14 inner halo fields which sample diverse substructures. In agreement with our previous analysis of colour-magnitude diagram morphologies, we find the resultant behaviours can be broadly separated into two categories. The SFHs of 'disc-like' fields indicate that most of their mass has formed since z~1, with one quarter of the mass formed in the last 5 Gyr. We find 'stream-like' fields to be on average 1.5 Gyr older, with <10 percent of their stellar mass formed within the last 5 Gyr. These fields are also characterised by an age--metallicity relation showing rapid chemical enrichment to solar metallicity by z=1, suggestive of an early-type progenitor. We confirm a significant burst of star formation 2 Gyr ago, discovered in our previous work, in all the fields studied here. The presence of these young stars in our most remote fields suggests that they have not formed in situ but have been kicked-out from through disc heating in the recent past.

In particular, we calculate the in-medium form factors entering the transition matrix elements defining this decay channel. It is found that the interactions of the participating particles with the medium lead to a considerable suppression in the branching ratio compared to the vacuum.

description: During the first year of the project, the smart uniform has been studied and designed. The prototype is composed of two layers: the external protective and performant uniform for first responders (FR), composed of a jacket and trousers, and then smart underwear with a T-shirt and leggings to be worn under the rescuer’s professional uniform. The model of the uniform is designed according to the anatomy of the body to be more comfortable and protective. In order to address gender-specific needs, the research project studied two different models according to the anatomy of the male and female body, even though this was not specified and requested in the DoA. The prototypes have been developed taking into account the Italian sample sizes: size L (50-52 IT) for the men’s uniform, size S (38-40 IT) for the women’s one.
 The design of the uniform is “user centered”, taking into account the human anatomy, functional and psycho-physical needs of the first responders and the characteristics of the disaster scenarios. In order to highly protect the FR during the rescue activity the uniform is made of different innovative, protective and performant materials.
 The fabric mainly used is the Jackal textile, produced by Textil Santanderina, chosen for its excellent mechanical and chemical properties combined with its sustainable characteristics. Moreover, in critical points of the body (elbows, shoulders, knees), the textile is improved with an additional custom fiberglass textile layer in order to give extra protection against abrasion. Also, removable flexible 3D printed protections are implemented in these critical points to ensure improved protection against shocks.
 Polymer-based, custom-designed sensors monitoring the health status of the first responder are embedded in the smart underwear, as they require tight contact of the sensors on the skin: Electrocardiogram (ECG) electrodes in the T-shirt, Electromyogram (EMG) electrodes and strain sensors for joint angles estimation in the leggings.
 Other sensors measuring environmental parameters, such as the concentration of both toxic and explosive gases (by a commercial multi-gas detector) and the X-radiation dose (by a polymeric sensor), are placed in different external pockets of the protective uniform.

description: We report on the calculation of the threshold soft function for heavy quark pair production in e+ e- annihilation at two-loop order. Our main result is a generalization of the familiar Drell-Yan threshold soft function to the case of non-zero primary quark mass. We set up a framework based on the method of differential equations which allows for the straightforward calculation of the bare soft function to arbitrarily high orders in the dimensional regularization parameter. Remarkably, we find that we can obtain the bare two-loop Drell-Yan soft function from the heavy quark soft function to the order in epsilon required for a two-loop calculation by making simple replacements. We expect that our results will be of use, both as an important input for precision physics calculations at linear colliders and, more formally, as a first step towards a better understanding of the connection between vacuum matrix elements of massive soft Wilson lines and vacuum matrix elements of massless soft Wilson lines.

description: SWINGS is a multidisciplinary 4-year project dedicated to elucidate trace element sources, transformations and sinks along a section crossing key areas of the Southern Ocean (SO). Major French contribution to the international GEOTRACES program (www.geotraces.org), SWINGS involves ca 80 scientists (21 international laboratories, 7 countries2). As core action of SWINGS, the SWINGS cruise (R/V Marion-Dufresne, MD229, Geotraces section GS02) started from La Reunion on January 11th 2021 and ended at La Reunion 57 days later (March 8th, 2021). This cruise explored a large part of the South Indian Ocean (Figure 0-2) in order to tackle the following objectives: 1) establish the relative importance of sedimentary, atmospheric and hydrothermal sources of TEIs in the Indian sector of the SO 2) investigate the drivers of the internal trace element cycles: biogenic uptake, remineralization, particle fate, and export, and 3) quantify TEI transport by the Antarctic Circumpolar Current and the numerous fronts at the confluence between Indian and Atlantic Oceans.
title: Die Wiederherstellung von Ordnung im Spiegel der konservativen Revolution Hofmannsthals am Beispiel von "Der Unbestechliche" (1923)
Creators: name: Javel, Florian William Michael Henri
Year: 2021

description: Die vorliegende Arbeit setzt sich mit dem in der Münchner Rede von 1928 Das Schrifttum als geistiger Raum der Nation präsentierten sprach- und kulturpolitischen Projekt der konservativen Revolution und deren Einfluss auf den geschilderten gesellschaftlichen Ordnungszustand im Lustspiel Der Unbestechliche von 1923 auseinander. Für diese Untersuchung werden kulturpolitische Verbindungen zwischen der Rede Hofmannsthals und dem Einfluss verschiedener Autor*innen hergestellt, die sich mit der gesellschaftlichen Ordnung im Rahmen der konservativen Revolution auseinandergesetzt haben, wie dies der Fall bei Paul Ludwig Landsberg und seinem mittelalterlichen Ordo-Gedanken oder Rudolf Pannwitz und seiner Europäischen Idee war. Der Einfluss der konservativen Revolution auf die Wiederherstellung von Ordnung im Lustspiel bildet den Kernpunkt dieser Untersuchung, wobei drei zentrale Aspekte der von Hofmannsthal skizzierten gesellschaftlichen Ganzheit darin ausgeführt werden. Die gesellschaftlichen Auswirkungen der Interaktion zwischen Religion, Revolution und dem Sozialen werden somit im Kontext der konservativen Revolution untersucht und in Verbindung zum Übergang eines chaotischen Zustands am Anfang des Lustspiels bis hin zur Bildung einer gemeinschaftlichen Einheit gegen Ende gesetzt. Die dadurch angestrebte Verwandlung des gesellschaftlichen Gefüges durch die individuelle Persönlichkeitsfindung der Figuren anhand der Einhaltung prädestinierter sozialer Rollen soll somit beleuchtet werden. Der Unbestechliche wird zusätzlich unter dem Aspekt eines reaktionären Produkts der gesellschaftlichen Desintegration der Nachkriegsjahre untersucht, die zu einer ambivalenten kulturpolitischen Platzierung Hofmannsthals geführt haben. Der Zwiespalt zwischen der Restauration einer alten Ordnung und einer gesellschaftlichen Revolution spielt in der Untersuchung des Lustspiels eine zentrale Rolle.

description: Ce rapport synthétise l'analyse des otolithes d'anguilles prélevés en 2021 dans le cadre du suivi des captures de cette espèce inscrite à la DCF (Data Collection Framework règlement CE n°199/2008 du conseil du 25 février 2008). 578 anguilles ont été prélevées de Juin à Octobre 2021 dans la Loire (303 individus), l’Adour (100 individus), la Dordogne (49 individus) et la Garonne (126 individus). La relation entre la longueur totale (Lt, mm) et le poids total (W, g) des anguilles prélevées en 2021 dans toute la France est du type W = 4.10-7Lt3,232. Ainsi, les anguilles présentent une allométrie isométrique (b=3,232) c’est-à-dire que le poids croit aussi vite que la longueur. L'institut IFREMER à travers le pôle national de Sclérochronologie à Boulogne-sur-Mer a préparé et interprété les otolithes, pièces calcifiées de l'oreille interne du poisson, permettant d’estimer leur âge. Pour chaque otolithe, un polissage mince sur le plan sagittal a été réalisé afin de permettre l’estimation de l'âge de chaque individu à l'aide du logiciel libre Icy. Tous les otolithes et ainsi que les données associées (taille, poids, date de capture, lieu...) sont stockés et gérés actuellement dans la base nationale d'archivage et de gestion des pièces calcifiées développée par l'IFREMER.

description: Many scientific investigations require that the values of a set of model parameters are estimated using recorded data. In Bayesian inference, information from both observed data and prior knowledge is combined to update model parameters probabilistically by calculating the posterior probability distribution function. Prior information is often described by a prior probability distribution. Situations arise in which we wish to change prior information during the course of a scientific project. However, estimating the solution to any single Bayesian inference problem is often computationally costly, as it typically requires many model samples to be drawn, and the data set that would have been recorded if each sample was true must be simulated. Recalculating the Bayesian inference solution every time prior information changes can therefore be extremely expensive. We develop a mathematical formulation that allows the prior information that is embedded within a solution, to be changed using variational methods, without recalculating the original Bayesian inference. In this method, existing prior information is removed from a previously obtained posterior distribution and is replaced by new prior information. We therefore call the methodology variational prior replacement (VPR). We demonstrate VPR using a 2D seismic full waveform inversion example, in which VPR provides similar posterior solutions to those obtained by solving independent inference problems using different prior distributions. The former can be completed within minutes on a laptop computer, whereas the latter requires days of computations using high-performance computing resources. We demonstrate the value of the method by comparing the posterior solutions obtained using three different types of prior information: uniform, smoothing and geological prior distributions.

On the consistent use of Constructed Observables

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We define "constructed observables" as relating experimental measurements to terms in a Lagrangian while simultaneously making assumptions about possible deviations from the Standard Model (SM), in other Lagrangian terms. Ensuring that the SM effective field theory (EFT) is constrained correctly when using constructed observables requires that their defining conditions are imposed on the EFT in a manner that is consistent with the equations of motion. Failing to do so can result in a "functionally redundant" operator basis and the wrong expectation as to how experimental quantities are related in the EFT. We illustrate the issues involved considering the $\rm S$ parameter and the off shell triple gauge coupling (TGC) verticies. We show that the relationships between $h \rightarrow V \bar{f} \, f$ decay and the off shell TGC verticies are subject to these subtleties, and how the connections between these observables vanish in the limit of strong bounds due to LEP. The challenge of using constructed observables to consistently constrain the Standard Model EFT is only expected to grow with future LHC data, as more complex processes are studied.

description: Otolithes entier de grondin perlon (Chelidonichthys lucerna) avec et sans brûlage pour estimation d'âge. Chez les poissons, l'âge est estimé à partir de l'analyse de pièces calcifiées (écaille, otolithe, vertèbre ... ) qui présentent des couches concentriques successives traduisant la croissance somatique. L'otolithe, situé dans l'oreille interne, est le plus utilisé en écologie. Le brûlage améliore la qualité des observations. Il peut être pratiqué jusqu’à la dénaturation des protéines qui prennent une couleur brune, rendant ainsi les zones de croissance hivernales (translucides) mieux visibles. Le brûlage se fait de différentes façons, à la flamme d'un bec bunsen ou sur une plaque électrique chauffante.
