description: Proxima Centauri b provides an unprecedented opportunity to understand the evolution and nature of terrestrial planets orbiting M dwarfs. Although Proxima Cen b orbits within its star's habitable zone, multiple plausible evolutionary paths could have generated different environments that may or may not be habitable. Here we use 1D coupled climate-photochemical models to generate self-consistent atmospheres for evolutionary scenarios predicted in our companion paper (Barnes et al., 2016). These include high-O2, high-CO2, and more Earth-like atmospheres, with either oxidizing or reducing compositions. We show that these modeled environments can be habitable or uninhabitable at Proxima Cen b's position in the habitable zone. We use radiative transfer models to generate synthetic spectra and thermal phase curves for these simulated environments, and instrument models to explore our ability to discriminate between possible planetary states. These results are applicable not only to Proxima Cen b, but to other terrestrial planets orbiting M dwarfs. Thermal phase curves may provide the first constraint on the existence of an atmosphere, and JWST observations longward of 7 microns could characterize atmospheric heat transport and molecular composition. Detection of ocean glint is unlikely with JWST, but may be within the reach of larger aperture telescopes. Direct imaging spectra may detect O4, which is diagnostic of massive water loss and O2 retention, rather than a photosynthesis. Similarly, strong CO2 and CO bands at wavelengths shortward of 2.5 μm would indicate a CO2-dominated atmosphere. If the planet is habitable and volatile-rich, direct imaging will be the best means of detecting habitability. Earth-like planets with microbial biospheres may be identified by the presence of CH4 and either photosynthetically produced O2 or a hydrocarbon haze layer.

Αρχικά, περιγράφεται η έννοια της καταπίεσης μέσα στο ευρύτερο πλαίσιο της πολιτικής σκέψης των Οθωμανών. Η εργασία επικεντρώνεται στην ανάλυση των διαφορετικών μορφών οικονομικής καταπίεσης: δίνεται έμφαση στις φορολογικές καταπιέσεις καθώς και σε μη συμβατικές περιπτώσεις καταπιέσεων. Επιπλέον, παρουσιάζονται τα προφίλ των προσώπων που εμφανίζονται στις πηγές ως καταπιεζόμενοι και καταπιεστές. Τέλος και μόνο εν μέρει, επιχειρείται να ενταχθεί το φαινόμενο στο ευρύτερο πλαίσιο της κοινωνικοοικονομικής εξέλιξης και μετασχηματισμού, που χαρακτήριζαν τους οθωμανικούς 17ο και 18ο αιώνες
description: The present thesis approaches the phenomenon of economic oppression in the Ottoman Empire during the 17th and 18th centuries, based on ottoman administrative sources. Initially, the notion of oppression is described in the wider context of ottoman political thought. The analysis focuses on the different forms of economic oppression: emphasis is given on fiscal oppression, abusive taxation methods and also on what this study describes as non-conventional cases of oppression. Moreover, both the profiles of the oppressed and the oppressors are presented exclusively as depicted in the archival sample. Finally, an attempt is partially made to set the phenomenon within the wider context of socio-economic development and transformation, which characterized the ottoman 17th and 18th centuries

description: This paper derives a set of easy-to-use tools designed to simplify calculations with birdtrack op- erators comprised of symmetrizers and antisymmetrizers. In particular, we present cancellation rules allowing one to shorten the birdtrack expressions of operators, and propagation rules identifying the circumstances under which it is possible to propagate symmetrizers past antisymmetrizers and vice versa. We exhibit the power of these simplification rules by means of a short example in which we apply the tools derived in this paper on a typical operator that can be encountered in the representation theory of SU(N) over the product space $V^{\otimes m}$ . These rules form the basis for the construction of compact Hermitian Young projection operators and their transition operators addressed in companion papers.

description: The rough Heston model is a very popular recent model in mathematical finance; however, the lack of Markov and semimartingale properties poses significant challenges in both theory and practice. A way to resolve this problem is to use Markovian approximations of the model. Several previous works have shown that these approximations can be very accurate even when the number of additional factors is very low. Existing error analysis is largely based on the strong error, corresponding to the L2 distance between the kernels. Extending earlier results by [Abi Jaber and El Euch, SIAM Journal on Financial Mathematics 10(2):309?349, 2019], we show that the weak error of the Markovian approximations can be bounded using the L1-error in the kernel approximation for general classes of payoff functions for European style options. Moreover, we give specific Markovian approximations which converge super-polynomially in the number of dimensions, and illustrate their numerical superiority in option pricing compared to previously existing approximations. The new approximations also work for the hyper-rough case H > -1/2.

description: We announce the discovery that WASP-20 is a binary stellar system, consisting of two components separated by $0.2578\pm0.0007^{\prime\prime}$ on the sky, with a flux ratio of $0.4639\pm 0.0015$ in the $K$-band. It has previously been assumed that the system consists of a single F9 V star, with photometric and radial velocity signals consistent with a low-density transiting giant planet. With a projected separation of approximately $60$ au between the two components, the detected planetary signals almost certainly originate from the brighter of the two stars. We reanalyse previous observations allowing for two scenarios, `planet transits A' and `planet transits B', finding that both cases remain consistent with a transiting gas giant. However, we rule out the `planet transits B' scenario because the observed transit duration requires star B to be significantly evolved, and therefore have an age much greater than star A. We outline further observations which can be used to confirm this finding. Our preferred `planet transits A' scenario results in the measured mass and radius of the planet increasing by 4$σ$ and 1$σ$, respectively.

description: Background: E-learning is recognised as a useful educational tool and is becoming more common in undergraduate medical education. This review aims to examine the scope and impact of e-learning interventions on medical student learning in clinical medicine, in order to aid medical educators when implementing e-learning strategies in programme curricula. Methods: A systematic review compliant with PRISMA guidelines that appraises study design, setting and population, context and type of evaluations. Specifc search terms were used to locate articles across nine databases: MEDLINE/PubMed, ScienceDirect, EMBASE, Cochrane Library, ERIC, Academic Search Complete, CINAHL, Scopus and Google Scholar. Only studies evaluating e-learning interventions in undergraduate clinical medical education between January 1990 and August 2021 were selected. Of the 4,829 papers identifed by the search, 42 studies met the inclusion criteria. Results: The 42 studies included varied in scope, cognitive domain, subject matter, design, quality and evaluation. The most popular approaches involved multimedia platforms (33%) and case-based approaches (26%), were interactive (83%), asynchronous (71%) and accessible from home (83%). Twelve studies (29%) evaluated usability, all of which reported positive feedback. Competence in use of technology, high motivation and an open attitude were key characteristics of successful students and preceptors. Conclusions: Medical education is evolving consistently to accommodate rapid changes in therapies and procedures. In today’s technologically adept world, e-learning is an efective and convenient pedagogical approach for the teaching of undergraduate clinical medicine.

description: The LHC is now studying in detail the couplings of the Higgs boson in order to determine if there is new physics. Many recent studies have examined the available fits to Higgs couplings from the perspective of constraining two Higgs doublet models (2HDM). In this paper we extend those studies to include constraints on the one loop couplings of the Higgs to gluons and photons. These couplings are particularly sensitive to the existence of new colored particles that are hard to detect otherwise and we use them to constrain a 2HDM augmented with a color-octet scalar, a possibility motivated by minimal flavor violation. We first study theoretical constraints on this model and then compare them with LHC measurements.

description: Background: Chronic renal failure is on the rise to cause of morbidity and mortality worldwide. According to the latest world health organization data, renal disease deaths in Ethiopia accounted for 1.47% of total deaths. However, limited study had previously been conducted to show the magnitude of CRF among medical outpatients at St. Paulo's hospital. Therefore, this study was designed to determine the magnitude of CRF and associated factors on medical outpatient's patients. Objective: To assess the magnitude & associated factors of chronic renal failure from Medical outpatient department in St. Paulo's Hospital, Ethiopia Method: This study used an institutional based cross sectional study. A trained nurse using structured questionnaire to interviewed participants. The survey questionnaire was first written in English and then translated into Amharic. 320 patients were interviewed from using a structured questioner and their Medical record revised. Data entry and analysis was done using SPSS statistical package version 20. The descriptive statistics was done. Logistic regression used to check for the presence of association between variables at the 95% confidence level. Result: The overall magnitude of CRF among medical outpatient department patients was 12.2%. CRF all age group likely develop the disease at statistically significant P value < 0.05. CRF cases with kidney infection were 5% greater than without kidney infection (AOR = 0.05, 95% CI 0.02, 0.16, P<0.01). In addition CRF cases with hypertension were 40% greater than without hypertension (AOR =0.43; 95% CI 0.18, 0.97; P=0.04). Conclusion: It is demonstrated that chronic renal failure common in all age group and common among male than females. Chronic renal failure magnitude among patients with hypertension and kidney infection had statistical significance. Chronic renal failure is rising at an alarming rate therefore, we recommend that relevant prevention, diagnostics, and therapeutic measures must undertake in all health facilities

description: The Littlest Seesaw (LS) model involves two right-handed neutrinos and a very constrained Dirac neutrino mass matrix, involving one texture zero and two independent Dirac masses, leading to a highly predictive scheme in which all neutrino masses and the entire PMNS matrix is successfully predicted in terms of just two real parameters. We calculate the renormalisation group (RG) corrections to the LS predictions, with and without supersymmetry, including also the threshold effects induced by the decoupling of heavy Majorana neutrinos both analytically and numerically. We find that the predictions for neutrino mixing angles and mass ratios are rather stable under RG corrections. For example we find that the LS model with RG corrections predicts close to maximal atmospheric mixing, $θ_{23}=45^\circ \pm 1^\circ$, in most considered cases, in tension with the latest NOvA results. The techniques used here apply to other seesaw models with a strong normal mass hierarchy.

description: BACKGROUND/OBJECTIVES: A claims-based model predicting 5-year mortality (Lund-Lewis) was developed in a 2008 cohort of North Carolina (NC) Medicare beneficiaries and included indicators of comorbid conditions, frailty, disability, and functional impairment. The objective of this study was to validate the Lund-Lewis model externally within a nationwide sample of Medicare beneficiaries. DESIGN: Retrospective validation study. SETTING: U.S. Medicare population. PARTICIPANTS: From a random sample of Medicare beneficiaries, we created four annual cohorts from 2008 to 2011 of individuals aged 66 and older with an office visit in that year. The annual cohorts ranged from 1.13 to 1.18 million beneficiaries. MEASUREMENTS: The outcome was 5-year all-cause mortality. We assessed clinical indicators in the 12 months before the qualifying office visit and estimated predicted 5-year mortality for each beneficiary in the nationwide sample by applying estimates derived in the original NC cohort. Model performance was assessed by quantifying discrimination, calibration, and reclassification metrics compared with a model fit on a comorbidity score. RESULTS: Across the annual cohorts, 5-year mortality ranged from 24.4% to 25.5%. The model had strong discrimination (C-statistics ranged across cohorts from.823 to.826). Reclassification measures showed improvement over a comorbidity score model for beneficiaries who died but reduced performance among beneficiaries who survived. The calibration slope ranged from.83 to.86; the model generally predicted a higher risk than observed. CONCLUSION: The Lund-Lewis model showed strong and consistent discrimination in a national U.S. Medicare sample, although calibration indicated slight overfitting. Future work should investigate methods for improving model calibration and evaluating performance within specific disease settings.

description: In this paper, we have presented a comprehensive study of Lorentz Invariance Violation (LIV) in the context of atmospheric neutrino experiment ICAL and long-baseline experiments T2HK and DUNE. Our study consists of the full parameter space of the LIV parameters (isotropic), i.e., six CPT violating LIV parameters ($a_{αβ}$) and six CPT conserving LIV parameters ($c_{αβ}$). In this study, our objective is to calculate the upper bound on all the LIV parameters with respect to the individual experiments and their combination. Our results show that DUNE gives the best sensitivity for the parameters $a_{ee}$, $a_{eμ}$, $a_{eτ}$ and $a_{μτ}$ in its 7 years of running whereas ICAL gives the best sensitivity on $a_{μμ}$, $a_{μτ}$, $c_{ee}$, $c_{μμ}$, $c_{ττ}$ and $c_{μτ}$ in its 10 years of running. For $a_{ττ}$, the sensitivity of DUNE and ICAL is similar. The combination of T2HK, DUNE and ICAL, gives the best sensitivity for $a_{eμ}$ and $a_{ee}$ with respect to all the existing bounds in the literature. For the CPT even diagonal parameters (isotropic) $c_{ee}$ and $c_{μμ}$, our work provides the first ever bounds.

Ειδικότερα, αναπτύχθηκε ένα νέο πρωτόκολλο για τη σύνθεση τρι- και τετρα-υποκατεστημένων Ν-πυρρολο-παραγώγων των εστέρων των αμινοξέων σε καλές έως υψηλές αποδόσεις. Τα αποτελέσματα συνοψίζονται ως εξής: Επιτεύχθηκε η σύνθεση μιας σειράς πολυ-υποκατεστημένων Ν-πυρρολο-παραγώγων των εστέρων των αμινοξέων απουσία καταλύτη σε πολικό πρωτικό διαλύτη μεθανόλη. Η διάρκεια της αντίδρασης είναι τέσσερεις ώρες και για την ολοκλήρωση της είναι απαραίτητη η θέρμανση στους 80oC. Με την εφαρμογή της παραπάνω συνθετικής μεθοδολογίας απομονώθηκε μια ποικιλία ενώσεων χωρίς προηγούμενη αναφορά στη βιβλιογραφία. Η μεθοδολογία αυτή με τη χρήση απλών αλειφατικών αλδεϋδών οδηγεί στα τρι- υποκατεστημένα πυρρόλια, ενώ με τη χρήση α-μεθυλο-υποκατεστημένων αλδεϋδών η αντίδραση λαμβάνει χώρα μέσω μιας 1,2-αλκυλο μετάθεσης, η οποία οδηγεί στον σχηματισμό τετρα-υποκατεστημένων πυρρολίων. Η αντίδραση βρίσκει ευρεία εφαρμογή σε εστέρες αμινοξέων, τόσο με αλειφατική πλευρική αλυσίδα (πχ. αλανίνη, βαλίνη, λευκίνη), όσο και με αρωματική (πχ. φαινυλαλανίνη). Στην περίπτωση που χρησιμοποιήθηκε ο μεθυλεστέρας του αμινοξέος σερίνη επιτεύχθηκε ο σχηματισμός τετρα-υδρο-πυρρολο-οξαζολινών κάτω από τις αντίστοιχες συνθήκες αντίδρασης
description: In this MSc thesis we studied the synthesis of poly-substituted pyrroles by a three-component reaction between aldehydes, amino acids’ esters and nitroalkenes. A new protocol was developed for the synthesis of three and tetra-substituted pyrrole’s derivatives of amino acids’ esters in good and high yields. The results are summarized as follows: The synthesis of a series of poly-substituted N-pyrrole-derivatives of the amino acids’ esters was succeeded in the absence of a catalyst in polar solvent methanol. The duration of the reaction is four hours and for its completion is necessary to heat at 80oC. By the application of the above synthetic methodology, a variety of compounds were synthesized without prior reference to the literature. This methodology using simple aliphatic aldehydes leads to the three-substituted pyrroles, while using α-methyl-substituted aldehydes the reaction takes place through a 1,2-alkyl displacement which leads to the formation of tetra-substituted pyrroles. The reaction shows broad application in amino acids’ esters, both with aliphatic side chain (alanine, valine, leucine) and aromatic side chain (phenylalanine). In the case where the serine’s methyl ester was used, tetrahydro-pyrrole-oxazolines were achieved under the corresponding reaction’s conditions

Spectral Functions with the Density Matrix Renormalization Group: Krylov-space Approach for Correction Vectors

description: Frequency-dependent correlations, such as the spectral function and the dynamical structure factor, help understand condensed matter experiments. Within the density matrix renormalization group (DMRG) framework, an accurate method for calculating spectral functions directly in frequency is the correction-vector method. The correction-vector can be computed by solving a linear equation or by minimizing a functional. This paper proposes an alternative to calculate the correction vector: to use the Krylov-space approach. This paper then studies the accuracy and performance of the Krylov-space approach, when applied to the Heisenberg, the t-J, and the Hubbard models. The cases studied indicate that Krylov-space approach can be more accurate and efficient than conjugate gradient, and that the error of the former integrates best when a Krylov-space decomposition is also used for ground state DMRG.

Η συνθετική μεθοδολογία έλαβε χώρα και σε μεγαλύτερη εργαστηριακή κλίμακα της τάξης των 3 mmol. Παράλληλα, προτάθηκε ένας πιθανός μηχανισμός, έχοντας διαφοροποίηση στο πρώτο βήμα από τους προτεινόμενους μηχανισμούς στη βιβλιογραφία για τη συγκεκριμένη αντίδραση, καθώς η ενεργοποίηση του νιτριλίου επιτυγχάνεται με την προσθήκη της μεθανόλης για το σχηματισμό ενός ιμιδικού ενδιαμέσου. Απομόνωση του ενδιαμέσου αυτού στις συνθήκες της αντίδρασής μας και χαρακτηρισμός του ενισχύει τον παραπάνω μηχανισμό
description: In the given research, was developed a simple and environmentally friendly methodology for the synthesis of heterocyclic molecules such as 2-imidazolines, 2-oxazolines and 1,4,5,6-tetrahydropyrimidines. A series of benzonitriles was used with different diamines and amino alcohols for the production of the desired products in great yields. The synthetic methodology took place on a lab-scale, at 3 mmol scale. In parallel, the mechanism that is suggested has a distinction in the first step, concerning the proposed mechanisms in the literature so far, as the activation of the nitrile is obtained by the addition of the methanol for the formation of the imidate intermediate. Isolation of this intermediate in our reaction conditions support the proposed mechanism

description: The main objective of Work Package (WP) 5 is to design, develop and upscale sortable mono-material packaging films, suitable for recycling and containing post-consumer recyclates (PCR). The developed film shall be suitable for the packaging of food and non-food products. The incorporated PCR will be the outcome of the improved sorting and treatment technologies of WP2 and WP3, and solely be sourced from food packaging. This is required to fulfil the premise of the Commission Regulation (EC) No 282/2008 of 27 March 2008 on recycled plastic materials and articles intended to come into contact with foods and amending Regulation (EC) No 2023/2006.

The films designed within this WP shall comply with the existing Design 4 Recycling (D4R) guidelines and contain more than 90% polyethylene (PE). Additionally, the novel film structure will contain at least 70% of PCR in one single layer. The development of high performance functional barriers is required, to effectively prevent migration of any residual contaminants from the PCR, and to keep them below the migration limits set out by legislations and European Food Safety Authority (EFSA).

The developments of WP2 and WP3 will be implemented in the mono-material packaging design, so that the novel material can be collected and sorted. Especially, the inclusion of tracers for improved sorting and an adequate choice of inks to be well deinkable will be respected. Moreover, the novel material will fulfil all gas barrier and mechanical requirements defined by the end users. As well all requirements regarding sealability and machinability at the end users’ packaging lines will be satisfied. Any possible effect on production efficiency or energy consumption should be reduced or avoided.

While Task 5.1 is dealing with the requirement collection from the end users, namely from the partners Nestlé, Amcor-Gent and Amcor-Kreuzlingen, Task 5.2 is targeting a screening of potential functional barriers to be used in the novel film structures. High-performance functional barrier combinations of inorganic or polymeric coatings will considered. Moreover, barrier lacquer formulations and top coating possibilities will be investigated. Commercially available barrier films will be benchmarked.

description: [Abridged] We use high-resolution $HST$ imaging and $e$-MERLIN 1.5-GHz observations of galaxy cores from the LeMMINGs survey to investigate the relation between optical structural properties and nuclear radio emission for a large sample of galaxies. We perform accurate, multi-component decompositions of new surface brightness profiles extracted from $HST$ images for 163 LeMMINGs galaxies and fit up to six galaxy components (e.g., bulges, discs, AGN, bars, rings, spiral arms, and nuclear star clusters) simultaneously with Sérsic and/or core-Sérsic models. By adding such decomposition data for 10 LeMMINGs galaxies from our past work, the final sample of 173 nearby galaxies (102 Ss, 42 S0s, 23 Es plus 6 Irr) with bulge stellar mass (typically) M_*, bulge ~ 10^6-10^12.5 M_sun, encompasses all optical spectral classes (LINER, Seyfert, ALG and H II). We show that the bulge mass can be significantly overestimated in many galaxies when components such as bars, rings and spirals are not included in the fits. We additionally implement a Monte Carlo method to determine errors on bulge, disc and other fitted structural parameters. Moving (in the opposite direction) across the Hubble sequence, i.e., from the irregular to elliptical galaxies, we confirm that bulges become larger, more prominent and round. Such bulge dominance is associated with a brighter radio core luminosity. We also find that the radio detection fraction increases with bulge mass. At M_*,bulge > 10^11 M_sun, the radio detection fraction is 77%, declining to 24% for M_bulge < 10^10 M_sun. Furthermore, we observe core-Sérsic bulges tend to be systematically round and to possess high radio core luminosities and boxy-distorted or pure elliptical isophotes.

description: We compute all the moments of the p-torsion in the first step of a filtration of the class group defined by Gerth for cyclic fields of degree p, unconditionally for p=3 and under GRH in general. We show that it satisfies a distribution which Gerth conjectured as an extension of the Cohen-Lenstra-Martinet conjectures. In the p=3 case this gives the distribution of the 3-torsion of the class group modulo the Galois invariant part. We follow the strategy used by Fouvry and Kluners in their proof of the distribution of the 4-torsion in quadratic fields.

description: In this master thesis, elements of the Orthodox and Folk Tradition were recorded in the Christmas short stories of Alexandros Papadiamantis and generally in the short stories concerning the Twelve Days and the connection between the Orthodox and the Folk Tradition was investigated. Specifically, 1) elements of the Folk Tradition, concerning a) the material life, b) the social life and c) the spiritual life, and 2) elements of the Orthodox Tradition from the references of Papadiamantis to the Holy Bible, to the etiquette of the Church, to church art and mostly to the church’s iconography, to the clergy and the people as participants in the holy liturgy, as reflected in these short stories. The time of writing of the short stories, their historical and cultural context illuminate the relevant material recorded there. Additionally, the special effect of the Kollyvades monks of Skiathos on the way Papadiamantis portrayed the Orthodox and Folk Tradition in the short stories of the Twelve Days was researched. For the preparation of this master’s thesis, the collected works of Alexandros Papadiamantis by N. Triantafyllopoulos from Domos publications were used

description: According to the $Λ$CDM cosmology, present-day galaxies with stellar masses $M_\star>10^{11} {\rm M}_\odot$ should contain a sizable fraction of dark matter within their stellar body. Models indicate that in massive early-type galaxies (ETGs) dark matter should account for $\sim60\%$ of the dynamical mass within five effective radii ($5 R_{\rm e}$). Most massive ETGs have been shaped through a two-phase process: the rapid growth of a compact core was followed by the accretion of an extended envelope through mergers. The exceedingly rare galaxies that have avoided the second phase, the so-called relic galaxies, are thought to be the frozen remains of the massive ETG population at $z\gtrsim2$. The best relic galaxy candidate discovered to date is NGC 1277, in the Perseus cluster. We used deep integral field GCMS data to revisit NGC 1277 out to an unprecedented radius of 6 kpc (corresponding to $5 R_{\rm e}$). By using Jeans anisotropic modelling we find a negligible dark matter fraction within $5 R_{\rm e}$ ($f_{\rm DM}(5 R_{\rm e})<0.05$; two-sigma confidence level), which is in tension with the expectation. Since the lack of an extended envelope would reduce dynamical friction and prevent the accretion of an envelope, we propose that NGC 1277 lost its dark matter very early or that it was dark matter deficient ab initio. We discuss our discovery in the framework of recent proposals suggesting that some relic galaxies may result from dark matter stripping as they fell in and interacted within galaxy clusters. Alternatively, NGC 1277 might have been born in a high-velocity collision of gas-rich proto-galactic fragments, where dark matter left behind a disc of dissipative baryons. We speculate that the relative velocities of $\approx2000 {\rm km/s}$ required for the latter process to happen were possible in the progenitors of the present-day rich galaxy clusters.

description: Using a probabilistic neural network and Lagrangian observations from the Global Drifter Program, we model the single particle transition probability density function (pdf) of ocean surface drifters. The transition pdf is represented by a Gaussian mixture whose parameters (weights, means and covariances) are continuous functions of latitude and longitude determined to maximise the likelihood of observed drifter trajectories. This provides a comprehensive description of drifter dynamics allowing for the simulation of drifter trajectories and the estimation of a wealth of dynamical statistics without the need to revisit the raw data. As examples, we compute global estimates of mean displacements over four days and lateral diffusivity. We use a probabilistic scoring rule to compare our model to commonly used transition matrix models. Our model outperforms others globally and in three specific regions. A drifter release experiment simulated using our model shows the emergence of concentrated clusters in the subtropical gyres, in agreement with previous studies on the formation of garbage patches. An advantage of the neural network model is that it provides a continuous-in-space representation and avoids the need to discretise space, overcoming the challenges of dealing with nonuniform data. Our approach, which embraces data-driven probabilistic modelling, is applicable to many other problems in fluid dynamics and oceanography.
