description: Το φαινόμενο της αλάτωσης εδαφών αποτελεί σοβαρή απειλή για τη γεωργία παγκοσμίως και ειδικότερα στις ξηρές και ημίξηρες παράκτιες περιοχές όπου εντοπίζεται ανισορροπία μεταξύ των διαθέσιμων αποθεμάτων ύδατος και της ζήτησης τους. Η περιοχή μελέτης, το Τυμπάκι, το οποίο βρίσκετε στο Νότιό-κεντρικό τμήμα της Κρήτης στο νομό Ηρακλείου αποτελεί μία από τις σημαντικότερες αγροτικές περιοχές της Κρήτης με αυξημένη ανάγκη αρδευτικών υδάτων. Οι περιορισμένοι υδάτινοι πόροι οδηγούν στην υπέρμετρη άντληση των υπόγειων υδάτων με συνέπεια την υφαλμύρινση του υπόγειου υδροφορέα. Για τη διερεύνηση των επιπτώσεων της άρδευσης με υφάλμυρο νερό στην καλλιέργεια τομάτας, πραγματοποιήθηκε πείραμα στο Πολυτεχνείο Κρήτης με συνθήκες που προσομοίωναν την περιοχή μελέτης. Το έδαφος προήλθε από το Τυμπάκι και αρδευόταν ελεγχόμενα με νερό μέσης (EC=2 dS m-1) και υψηλής αλατότητας (EC=3,5 dS m-1), ενώ χρησιμοποιήθηκε και υποβαθμισμένο έδαφος, έδαφος δηλαδή που είχε υποστεί παρόμοια μεταχείριση σε προηγούμενο πείραμα. Για την αντιμετώπιση των επιπτώσεων της αλατότητας χρησιμοποιήθηκαν βιολογικές τεχνικές και συγκεκριμένα ο ωφέλιμος μύκητας T. harzianum και το χουμικό οξύ Black Earth. Το πείραμα αποτελείτο από συνολικά 40 γλάστρες, οι οποίες είχαν χωριστεί σε 8 σειρές των 5 γλαστρών και σε κάθε σειρά εξεταζόταν διαφορετική μεταχείριση. Συγκεκριμένα, (α) οι σειρές άκρου ήταν προστατευτικές και τα αποτελέσματα τους δεν λήφθηκαν υπόψη, (β) στις μισές από τις εναπομείναντες σειρές χρησιμοποιήθηκε το υποβαθμισμένο έδαφος και (γ) στις υπόλοιπες το φρέσκο έδαφος. Για τις δύο περιπτώσεις εδάφους έγινε χρήση διαφορετικής βιολογικής τεχνικής σε κάθε σειρά. Η συγκεκριμένη εργασία εστίασε περισσότερο στην επίδραση της αλατότητας στη χλωροφύλλη των φυτών η οποία αποτελεί σημαντικό δείκτη υγείας τους. Ύστερα από 4 εδαφικές δειγματοληψίες και συστηματική μέτρηση της χλωροφύλλης, τα αποτελέσματα έδειξαν ότι το φρέσκο έδαφος λειτούργησε καλύτερα από ότι το υποβαθμισμένο στη διατήρηση υψηλού επιπέδου χλωροφύλλης στα φυτά καθώς και στην παραγωγή μεγαλύτερου αριθμού καρπών. Παρ’ όλα αυτά οι μεταχειρίσεις υποβαθμισμένου εδάφους σημείωσε καλύτερα αποτελέσματα στη απόδοση παραγωγής. Τα αποτελέσματα του πειράματος έδειξαν ακόμη ότι ο μύκητας T.harzianum ευνόησε περισσότερο τα φυτά από ότι το χουμικό οξύ. Δε βρέθηκε κάποια φανερή συσχέτιση της χλωροφύλλης με την απόδοση παραγωγής συνεπώς στο μέλλον θα πρέπει να δοθεί περαιτέρω έμφαση σε άλλες παραμέτρους.

description: Neutrino interactions with protons and neutrons probe their deep structure and may reveal new physics. The higher the neutrino energy, the sharper the probe. So far, the neutrino-nucleon ($νN$) cross section is known across neutrino energies from a few hundred MeV to a few PeV. Soon, ultra-high-energy (UHE) cosmic neutrinos, with energies above 100 PeV, could take us farther. So far, they have evaded discovery, but upcoming UHE neutrino telescopes endeavor to find them. We present the first detailed measurement forecasts of the UHE $νN$ cross section, geared to IceCube-Gen2, one of the leading detectors under planning. We use state-of-the-art ingredients in every stage of our forecasts: in the UHE neutrino flux predictions, the neutrino propagation inside Earth, the emission of neutrino-induced radio signals in the detector, their propagation and detection, and the treatment of backgrounds. After 10 years, if at least a few tens of UHE neutrino-induced events are detected, IceCube-Gen2 could measure the $νN$ cross section at center-of-mass energies of $\sqrt{s} \approx 10-100$ TeV for the first time, with a precision comparable to that of its theory prediction.

description: Η περιοχή στο Τυμπάκι του Ηρακλείου Κρήτης υπόκειται σε υφαλμύρωση του υπόγειου υδροφορέα, λόγω της αυξημένης άντλησης νερού άρδευσης. Ως αποτέλεσμα, τα θαλάσσια ύδατα εισχωρούν στον υπόγειο υδροφορέα και με την άρδευση μειώνουν σημαντικά την ποιότητα των εδαφών. Έτσι, προκύπτουν αρνητικές επιπτώσεις στις φυτικές καλλιέργειες, οι οποίες έχουν υψηλό οικονομικό κόστος στους αγρότες. Γι’ αυτό το λόγο, διεξάχθηκε ένα θερμοκηπιακό πείραμα στην περιοχή του Πολυτεχνείου Κρήτης, με σκοπό τον εντοπισμό βέλτιστων καλλιεργητικών τεχνικών. Κατά τη διάρκεια του πειράματος, έλαβε μέρος ανάλυση του νατρίου στα φύλλα, στο έδαφος και στα στραγγίσματα φυτών τομάτας, καθώς επίσης και στις χημικές ιδιότητες του εδάφους, όπως ηλεκτρική αγωγιμότητα του εδάφους (ECe), λόγος προσρόφησης νατρίου (SAR), pH, ολικό άζωτο (TN), αμμωνιακό και νιτρικό άζωτο (N-NH4+, N-NO3-), ολικός φωσφόρος (TP) και ολικός οργανικός άνθρακας (TOC). Πραγματοποιήθηκαν οκτώ μεταχειρίσεις, με πέντε φυτά ανά μεταχείριση του φυτού τομάτας Solanum lycopersicum L. (εμπορική ονομασία: Ελπίδα F1), με νερό άρδευσης ηλεκτρικής αγωγιμότητας ECLow=0.45 ± 0.05 dS·m-1, ECMedium=2.0 dS·m-1, και ECHigh=3.5 dS·m-1. Οι μεταχειρίσεις μέτριας αλατότητας περιείχαν υποβαθμισμένο έδαφος, ενώ οι υψηλής αλατότητας φρέσκο. Για την αντιμετώπιση της αλατότητας χρησιμοποιήθηκαν ως βιολογικές μέθοδοι, ο ωφέλιμος μύκητας T. harzianum και ένα εμπορικό σκεύασμα χουμικού οξέος. Από τις οκτώ μεταχειρίσεις, οι δύο λειτουργούσαν ως πρότυπα, ενώ τόσο στο φρέσκο όσο και στο υποβαθμισμένο έδαφος, η πρώτη μεταχείριση είχε επιπλέον το μύκητα T. harzianum και η δεύτερη το χουμικό οξύ. Σύμφωνα με τα αποτελέσματα συμπεραίνεται ότι στις χημικές ιδιότητες του εδάφους, καμία από τις βιολογικές τεχνικές δεν ξεχώρισε, σε σχέση με τις μεταχειρίσεις που δεν εφαρμόστηκε ο T. harzianum ή το χουμικό οξύ. Όμως, όσον αφορά το νάτριο στον ιστό του φυτού, το T. harzianum συνέβαλε στην καλύτερη παρεμπόδιση του από τα φύλλα του φυτού, τόσο στην περίπτωση του υποβαθμισμένου, όσο και στου φρέσκου εδάφους.

description: In this article, the superconducting and normal state properties of TlBi$_2$ with the AlB$_2$-type structure were studied by the resistivity, magnetization and specific heat measurements. It was found that bulk superconductivity with $T_{C}$ = 6.2 K emerges in TlBi$_2$, which is a phonon-mediated $s$-wave superconductor with a strong electron-phonon coupling ($λ$$_{ep}$ = 1.38) and a large superconducting gap ($Δ_{0}$/$k_{B}T_{C}$ = 2.25). We found that the $ρ$($T$) exhibits an unusual $T$-linear dependence above 50 K, and can be well described by the Fermi-liquid theory below 20 K. Interestingly, its Kadowaki-Woods ratio $A/γ^{2}$ [9.2$\times$10$^{-5}$ $μΩ$ cm(mol K$^{2}$/mJ)$^{2}$] is unexpectedly one order of magnitude larger than that obtained in many heavy Fermi compounds, although the electron correlation is not so strong.

description: The subject of this diploma thesis is the study of the seismic hazard of the urban complex of the city of Chania. The implementation is performed utilizing QuakeIST software, which operates in Geographical Information Systems  (GIS) computational environment, and in particular, QGIS software. The main aim of this thesis is to realistically define the problem of the seismic hazard and to predict the possible impacts (damages and losses) as well as their probability of occurrence in a future seismic event. Another objective is to formulate a methodology that could potentially be used by the authorities as an effective decision-making tool for the implementation of appropriate techno-economic plans and seismic protection measures to prevent and reduce losses (primarily human, but also financial) in the future.
The thesis begins with an introduction to the general concepts of seismology and a brief analysis of the seismic and geological setting of the area of the ,unicipality of Chania. Next, a presentation of general elements and concepts for GIS, and also for QGIS software in particular, is provided. Subsequently, in the main part of the thesis, initially, the basic information regarding QuakeIST software are presented and its functions are described. Then, the process of studying the Chania urban complex is described in details, and finally the obtained results are presented. The thesis concludes with the interpretation of the results along with a comparison with previous relevant studies in the examined area. Finally, suggestions for future continuation of this investigation are provided.

description: We describe measurements of the uniaxial magnetic anisotropy and spin-flop rotation of the Néel vector in antiferromagnetic CuMnAs thin films using neutron diffraction. The suppression of the magnetic (100) peak under magnetic fields is observed for films as thin as 20 nm indicating that they undergo a spin-flop transition. Good agreement is found between neutron diffraction and electron transport measurements of the spin-flop rotation in the same layer, with a similar shape and hysteresis of the obtained curves, while the neutron measurements provide a quantitative determination of the spin flop extent throughout the antiferromagnet layer.

description: We present a convolutional autoencoder to denoise pulses from a p-type point contact high-purity germanium detector similar to those used in several rare event searches. While we focus on training procedures that rely on detailed detector physics simulations, we also present implementations requiring only noisy detector pulses to train the model. We validate our autoencoder on both simulated data and calibration data from an $^{241}$Am source, the latter of which is used to show that the denoised pulses are statistically compatible with data pulses. We demonstrate that our denoising method is able to preserve the underlying shapes of the pulses well, offering improvement over traditional denoising methods. We also show that the shaping time used to calculate energy with a trapezoidal filter can be significantly reduced while maintaining a comparable energy resolution. Under certain circumstances, our denoising method can improve the overall energy resolution. The methods we developed to remove electronic noise are straightforward to extend to other detector technologies. Furthermore, the latent representation from the encoder is also of use in quantifying shape-based characteristics of the signals. Our work has great potential to be used in particle physics experiments and beyond.

description: Photoacoustic spectroscopy (PAS) based gas sensors with high sensitivity, wide dynamic range, low cost, and small footprint are desirable across a broad range of applications in energy, environment, safety, and public health. However, most works have focused on either acoustic resonator to enhance acoustic wave or optical resonator to enhance optical wave. Herein, we develop a gas sensor based on doubly resonant PAS in which the acoustic and optical waves are simultaneously enhanced using combined optical and acoustic resonators in a centimeter-long configuration. Not only the lower detection limit is enhanced by the double standing waves, but also the upper detection limit is expanded due to the short resonators. As an example, we developed a sensor by detecting acetylene (C2H2), achieving a noise equivalent absorption of 5.7*10-13 cm-1 and a dynamic range of eight orders. Compared to the state-of-the-art PAS gas sensors, the developed sensor increases the sensitivity by two orders of magnitude and extends the dynamic range by three orders of magnitude. Besides, a laser-cavity-molecule locking strategy is proposed to provide additional flexibility of fast gas detection.
Effect of strain and sulfur vacancies on the luminescence and valley polarization properties of CVD grown monolayer MoS$_2$ films

description: Using temperature dependent photoluminescence (PL), polarization resolved PL and Raman spectroscopy, we investigate the effect of in situ vacuum annealing as well as the relaxation of strain on the luminescence and the valley polarization properties of large area strictly monolayer (1L)-MoS$_2$, grown on sapphire and SiO$_2$/Si substrates by a microcavity based chemical vapor deposition (CVD) technique. The study shows that the strain as well as the physisorption of air molecules at the sulfur vacancy ($V_S$) sites play key roles in governing the optical quality of CVD grown 1L-MoS$_2$. Removal of air molecules from the $V_S$ sites enhances the relative strength of the A-exciton/trion transition as compared to the broad luminescence (BL) band arising from those defects at low temperatures. It has also been found that such removal helps in improving the valley polarization property of the film. Relaxation of biaxial tensile strain, which has been achieved by post growth transferring of 1L-MoS$_2$ film from the sapphire to a SiO$_2$/Si substrate by a polystyrene assisted transfer process, is also found to be helpful to get back the high polarization character ($\sim$80%) of the valleys. The study further shows that the transfer process not only facilitates the removal of physisorbed air molecules from the $V_S$ sites but also puts in place a long lasting capping layer on MoS$_2$ that shields the film from reacting with air and hence enhances the relative yield of A-exciton/trion transition by suppressing the BL transition. The study thus creates an opportunity to use CVD grown large area 1L-MoS$_2$ for the development of optoelectronic as well as valleytronic devices for practical applications for the future.
Investigation of deflection angle for muon energy classification in muon scattering tomography via GEANT4 simulations

description: In muon scattering tomography, the investigated materials are discriminated according to the scattering angle that mainly depends on the atomic number, the density, and the thickness of the medium at a given energy value. The scattering angles at different initial energies also provide the opportunity to classify the incoming muons into a number of energy groups. In this study, by employing the GEANT4 code, we show that the deflection angle exponentially decays as a function of energy, and the numerical values for the current configuration are below the detector accuracy except the initial energy bins owing to the low-Z, low density, and low thickness of the current plastic scintillators. This implies the necessity of additional components that provoke the muon scattering. Therefore, we introduce stainless steel surfaces into the top and bottom sections in order to amplify the deflection angle as well as to reduce the uncertainty, thereby improving the detector performance.

description: We extend the confined-density-dependent-mass (CDDM) model to include isospin dependence of the equivalent quark mass. Within the confined-isospin-density-dependent-mass (CIDDM) model, we study the quark matter symmetry energy, the stability of strange quark matter, and the properties of quark stars. We find that including isospin dependence of the equivalent quark mass can significantly influence the quark matter symmetry energy as well as the properties of strange quark matter and quark stars. While the recently discovered large mass pulsars PSR J1614-2230 and PSR J0348+0432 with masses around $2M_{\odot}$ cannot be quark stars within the CDDM model, they can be well described by quark stars in the CIDDM model. In particular, our results indicate that the two-flavor $u$-$d$ quark matter symmetry energy should be at least about twice that of a free quark gas or normal quark matter within conventional Nambu-Jona-Lasinio model in order to describe the PSR J1614-2230 and PSR J0348+0432 as quark stars.

Η παρούσα διπλωματική εργασία αποσκοπεί στην αξιολόγηση του εν λόγω δικτύου
γεωτρήσεων και για αυτό το λόγο, διεξήχθησαν δοκιμαστικές αντλήσεις κατά βαθμίδες σε ένα ιδιαίτερα μεγάλο τμήμα του. Οι δοκιμές έγιναν με μεταβαλλόμενη παροχή, συνεχόμενη (χωρίς δηλ. να σταματήσει η άντληση και αυξάνοντας τη παροχή μεταξύ των διακριτών σταδίων). Κάθε στάδιο είχε διάρκεια μιας ώρας και ενδιάμεσα των σταδίων η άντληση δεν διακοπτόταν αλλά αυξανόταν η παροχή.
Κατά τη διάρκεια της δοκιμής καταγραφόταν η πτώση στάθμης, η παροχή άντλησης και η ηλεκτρική αγωγιμότητα. Από την επεξεργασία των δεδομένων προσδιορίστηκαν η ειδική πτώση στάθμης και η ειδική παροχή, παράμετροι αναγκαίοι στον καθορισμό των απωλειών φορτίου του υδροφορέα και των απωλειών φορτίου των γεωτρήσεων. Με βάση τα αποτελέσματα αξιολογήθηκαν τόσο τα τεχνικά χαρακτηριστικά των γεωτρήσεων όσο και τα υδραυλικά χαρακτηριστικά του υδροφορέα.
Συμπερασματικά, προκύπτει ότι ένα ιδιαίτερα σημαντικό τμήμα του δικτύου των
γεωτρήσεων, που έχει διαμορφωθεί στη περιοχή παρουσιάζει κατασκευαστικά προβλήματα ή σοβαρή υποβάθμιση.
Dynamical properties of spatial discretizations of a generic homeomorphism

Publisher: name: arXiv

Subjects: subject: Dynamical Systems (math.DS)
subject: FOS: Mathematics

description: This paper concerns the link between the dynamical behaviour of a dynamical system and the dynamical behaviour of its numerical simulations. Here, we model numerical truncation as a spatial discretization of the system. Some previous works on well chosen examples show that the dynamical behaviours of dynamical systems and of their discretizations can be quite different. In this paper we are interested in generic homeomorphisms of compact manifolds. So our aim is to tackle the following question: can the dynamical properties of a generic homeomorphism be detected on the spatial discretizations of this homeomorphism? We study both conservative and dissipative homeomorphisms (i.e. with or without the assumption that the homeomorphism preserves a given measure). We will prove that the dynamics of a single discretization of a generic conservative homeomorphism does not depend on the homeomorphism itself, but rather on the grid used for the discretization. Therefore, dynamical properties of a given generic conservative homeomorphism cannot be detected using a single discretization. Nevertheless, we will also prove that some dynamical features of a generic conservative homeomorphism (such as the set of the periods of all periodic points) can be read on a sequence of finer and finer discretizations. The dissipative case is somehow opposite: we will see that the dynamics of a generic dissipative homeomorphism is well-approximated by the dynamics of any fine enough discretization of this homeomorphism.

Global Access Program

DataCite

description: DataCite is a leading global non-profit organization that provides persistent identifiers (PIDs) for research data and other research outputs. DataCite has introduced the Global Access Program (GAP) with the aim to improve equity, access to and adoption of persistent identifier (PID) infrastructure for communities in under-represented countries, including all African countries. African research is still not receiving the right visibility due to several factors, including a lack of appropriate repositories with trusted PIDs, inadequate infrastructure to project the outputs, poor metadata for visibility, technical gaps, low awareness about the importance of PIDs, and institutional buy-in. Through GAP, DataCite’s dedicated resources will collaborate with the research community and stakeholders to promote Africa’s indigenous knowledge and contributions to research outputs. In his presentation, Bosun Obilye introduces DataCite's Global Access Program (GAP) with a focus on Africa.

description: This article studies local and global inference for smoothing spline estimation in a unified asymptotic framework. We first introduce a new technical tool called functional Bahadur representation, which significantly generalizes the traditional Bahadur representation in parametric models, that is, Bahadur [Ann. Inst. Statist. Math. 37 (1966) 577-580]. Equipped with this tool, we develop four interconnected procedures for inference: (i) pointwise confidence interval; (ii) local likelihood ratio testing; (iii) simultaneous confidence band; (iv) global likelihood ratio testing. In particular, our confidence intervals are proved to be asymptotically valid at any point in the support, and they are shorter on average than the Bayesian confidence intervals proposed by Wahba [J. R. Stat. Soc. Ser. B Stat. Methodol. 45 (1983) 133-150] and Nychka [J. Amer. Statist. Assoc. 83 (1988) 1134-1143]. We also discuss a version of the Wilks phenomenon arising from local/global likelihood ratio testing. It is also worth noting that our simultaneous confidence bands are the first ones applicable to general quasi-likelihood models. Furthermore, issues relating to optimality and efficiency are carefully addressed. As a by-product, we discover a surprising relationship between periodic and nonperiodic smoothing splines in terms of inference.

description: As the effects of the climate change become more pronounced and the energy demand is increasing, the interest for renewable energy investments is growing globally. However, the exploitation of the renewable energy resources has to be implemented in a rational and sustainable way, taking into account both the maximization of the renewable energy potential, but also the social and environmental implications accruing.
This study aims to develop a useful methodology for clarifying and prioritizing at a regional level, the most suitable locations for siting wind and solar farms, as well as biomass and biogas plants. By employing Geographical Information Systems (GIS) and the Analytical Hierarchy Process (AHP), the sustainable siting areas for renewable energy installations siting are identified, applying a spatial multi-criteria decision-making (MCDM) approach.
The adopted methodology identifies the available siting areas for each Renewable Energy System (RES), based on exclusion criteria derived from the Specific Framework for the Spatial Planning and Sustainable Development for the Renewable Energy Sources (SFSPSD-RES) and related legislation. Furthermore, the available siting areas for each renewable energy technology are evaluated through a multicriteria analysis, based on evaluation criteria derived from the literature. Moreover, the sustainable locations for each renewable energy technology are derived, considering also the relative importance of the selected criteria, through the AHP implementation and the criteria pair-wise comparisons performed by involved energy-related groups.
Therefore, the main result of this study is the development of a strategic planning methodology for the sustainable siting of RES, which was applied for the case study of the Regional Unit of Rethymno. The developed methodology employs different types of criteria, such as techno-economic and socio-environmental, it takes into account the distinct opinions of different stakeholders and it enables the evaluation of different scenarios.

description: It is generally believed that long-duration gamma-ray bursts (GRBs) are associated with massive star core-collapse, whereas short-duration GRBs are associated with mergers of compact star binaries. However, growing observations have suggested that oddball GRBs do exist, and multiple criteria (prompt emission properties, supernova/kilonova associations, and host galaxy properties) rather than burst duration only are needed to classify GRBs physically. A previously reported long-duration burst, GRB 060614, could be viewed as a short GRB with extended emission if it were observed at a larger distance and was associated with a kilonova-like feature. As a result, it belongs to the Type-I (compact star merger) GRB category and is likely of the binary neutron star merger origin. Here we report a peculiar long-duration gamma-ray burst, GRB 211211A, whose prompt emission properties in many aspects differ from all known Type-I GRBs, yet its multi-band observations suggest a non-massive-star origin. In particular, significant excess emission in both optical and near-infrared wavelengths has been discovered, which resembles kilonova emission as observed in some Type-I GRBs. These observations point towards a new progenitor type of GRBs. A scenario invoking a white dwarf-neutron star merger with a post-merger magnetar engine provides a self-consistent interpretation for all the observations, including prompt gamma-rays, early X-ray afterglow, as well as the engine-fed kilonova emission.

description: Standard evolutionary optimization algorithms assume that the evaluation of the objective and constraint functions is straightforward and computationally cheap. However, in many real-world optimization problems, these evaluations involve computationally expensive numerical simulations or physical experiments. Surrogate-assisted evolutionary algorithms (SAEAs) have recently gained increased attention for their performance in solving these types of problems. The main idea of SAEAs is the integration of an evolutionary algorithm with a selected surrogate model that approximates the computationally expensive function. In this paper, we propose a surrogate model based on a Lipschitz underestimation and use it to develop a differential evolution-based algorithm. The algorithm, called Lipschitz Surrogate-assisted Differential Evolution (LSADE), utilizes the Lipschitz-based surrogate model, along with a standard radial basis function surrogate model and a local search procedure. The experimental results on seven benchmark functions of dimensions 30, 50, 100, and 200 show that the proposed LSADE algorithm is competitive compared with the state-of-the-art algorithms under a limited computational budget, being especially effective for the very complicated benchmark functions in high dimensions.

description: PD curve calibration refers to the transformation of a set of rating grade level probabilities of default (PDs) to another average PD level that is determined by a change of the underlying portfolio-wide PD. This paper presents a framework that allows to explore a variety of calibration approaches and the conditions under which they are fit for purpose. We test the approaches discussed by applying them to publicly available datasets of agency rating and default statistics that can be considered typical for the scope of application of the approaches. We show that the popular 'scaled PDs' approach is theoretically questionable and identify an alternative calibration approach ('scaled likelihood ratio') that is both theoretically sound and performs better on the test datasets. Keywords: Probability of default, calibration, likelihood ratio, Bayes' formula, rating profile, binary classification.

On non-ideal chemical-reaction networks and phase separation

description: Much of the theory on chemical-reaction networks (CRNs) has been developed in the ideal-solution limit, where interactions between the solutes are negligible. However, there is a large variety of phenomena in biological cells and soft-matter physics which appear to deviate from the ideal-solution behaviour. Particularly striking is the case of liquid-liquid phase separation, which is typically caused by inter-particle interactions. Here, we revisit a number of known results in the domain of ideal CRNs, and we generalise and adapt them to arbitrary interactions between the solutes which stem from a given free energy. Among these is the form of the steady-state probability distribution and Lyapunov functions for complex-balanced networks, where the creation and annihilation rates are equal for all chemical complexes which appear as reactants or products in the CRN. Finally, we draw a phase diagram for complex-balanced reaction-diffusion solutions based on the minimisation of such Lyapunov function with a rationale similar to that of equilibrium thermodynamics, but for systems that may sustain non-equilibrium chemical currents at steady state. Nevertheless, we find that complex-balanced networks are not sufficient to create diffusion currents at steady state.

description: Objective. We evaluated eight recruitment methods (Craigslist, Facebook ads, Google AdWords, in-person, newspaper, parenting magazines, ResearchMatch, and direct mailing) in terms of their ability to accrue fathers of 3- to 7-year-old children into a laboratory-based behavioral trial for parents. The trial was related to child obesity risk and parental health behaviors.Design. Each recruitment method was implemented such that half its occurrences advertised for fathers only, and half advertised for mothers and fathers. Methods were evaluated in terms of number of fathers recruited, cost- and time-efficiency, response rates, and demographic characteristics of individuals recruited. We also assessed fathers’ and mothers’ motivations for participating in the study. 101 fathers and 260 mothers were recruited.Results. Father-targeted ads were essential for father recruitment; 79% of accruals from father-targeted ads were male, whereas only 14% of accruals from parent-targeted ads were male. Craigslist, ResearchMatch, and Facebook ads were the most cost-efficient for accruing fathers. A greater proportion of fathers was motivated by increasing fathers’ representation in research (16%) compared to mothers who wished to increase mothers’ representation in research (5.4%). Similar proportions of fathers and mothers were motivated by improving their parenting knowledge and improving their child’s health.Conclusions. Future researchers should employ father-targeted recruitment materials (rather than parent-targeted) that capitalize on fathers’ unique motivations for participating in research.

description: Physics-informed neural networks (PINNs) leverage neural-networks to find the solutions of partial differential equation (PDE)-constrained optimization problems with initial conditions and boundary conditions as soft constraints. These soft constraints are often considered to be the sources of the complexity in the training phase of PINNs. Here, we demonstrate that the challenge of training (i) persists even when the boundary conditions are strictly enforced, and (ii) is closely related to the Kolmogorov n-width associated with problems demonstrating transport, convection, traveling waves, or moving fronts. Given this realization, we describe the mechanism underlying the training schemes such as those used in eXtended PINNs (XPINN), curriculum regularization, and sequence-to-sequence learning. For an important category of PDEs, i.e., governed by non-linear convection-diffusion equation, we propose reformulating PINNs on a Lagrangian frame of reference, i.e., LPINNs, as a PDE-informed solution. A parallel architecture with two branches is proposed. One branch solves for the state variables on the characteristics, and the second branch solves for the low-dimensional characteristics curves. The proposed architecture conforms to the causality innate to the convection, and leverages the direction of travel of the information in the domain. Finally, we demonstrate that the loss landscapes of LPINNs are less sensitive to the so-called "complexity" of the problems, compared to those in the traditional PINNs in the Eulerian framework.
