description: A density matrix theory of electron transport and optical gain in quantum cascade lasers in an external magnetic field is formulated. Starting from the general quantum kinetic treatment, we describe the intra- and inter-period electron dynamics at the non-Markovian, Markovian and Boltzmann approximation levels. Interactions of electrons with longitudinal optical phonons and classical light field are included in the present description. The non-Markovian calculation for a prototype structure reveals significantly different gain spectra in terms of linewidth and additional polaronic features in comparison to the Markovian and Boltzmann ones. Despite strongly opposed interpretations of the origin of the transport processes in the non-Markovian or Markovian and the Boltzmann approaches, they yield comparable values of the current densities.

description: Admitting non-Riemannian geometries, Double Field Theory extends the notion of spacetime beyond the Riemannian paradigm. We identify a class of singular spacetimes known in General Relativity with regular non-Riemannian geometries. The former divergences merely correspond to coordinate singularities of the generalised metric for the latter. Computed in string frame, they feature an impenetrable non-Riemannian sphere outside of which geodesics are complete with no singular deviation. Approaching the non-Riemannian points, particles freeze and strings become (anti-)chiral.

Year: 2006
Subjects: subject: Chaotic Dynamics (nlin.CD)

description: We study 1-dimensional coupled map lattices consisting of diffusively coupled Tchebyscheff maps of N-th order. For small coupling constants a we determine the invariant 1-point and 2-point densities of these nonhyperbolic systems in a perturbative way. For arbitrarily small couplings a>0 the densities exhibit a selfsimilar cascade of patterns, which we analyse in detail. We prove that there are log-periodic oscillations of the density both in phase space as well as in parameter space. We show that expectations of arbitrary observables scale with \sqrt{a} in the low-coupling limit, contrasting the case of hyperbolic maps where one has scaling with a. Moreover we prove that there are log-periodic oscillations of period \log N^2 modulating the \sqrt{a}-dependence of the expectation value of any given observable.

Growth management : preserving livability in Greater Vancouver
Creators: name: Bannister, Carl William
Publisher: name: University of British Columbia
Year: 2009

description: The intent of this thesis is twofold. First, to investigate the feasibility of a comprehensive and integrated growth management approach to the complex, pervasive, and persistent growth issues threatening Greater Vancouver's Hvability. Second, to establish the parameters of a growth management strategy tailored to the needs and requirements of the Greater Vancouver region, and the supportive institutional conditions necessary for its effective and efficient implementation and operation. These tasks were accomplished through a systematic review and analysis of: contemporary growth management theory; Canadian and American experiences with the application of this theory; the theoretical and administrative foundations of land-use planning; Greater Vancouver's growth issues and concerns, including past and current efforts to address these issues and concerns; and, Greater Vancouver's institutional environment, including systems of governance and organizational structures. The thesis concludes that the development, implementation, and enduring support of a comprehensive, integrated growth management program can achieve the preservation of Greater Vancouver's Hvability. This is, however, contingent on the undertaking of several critical actions including: legislative enactment of a comprehensive and binding growth management program; restoration of regional planning powers; continued political and public support for regional growth management and, the development and support of an ongoing public process designed to build consensus, educate, and generate feedback.

description: Το θέμα της παρούσας διπλωματικής εργασίας αφορά τον Ζακύνθιο λόγιο Αντώνιο Κατήφορο (1685-1763). Πρόκειται για έναν εκκλησιαστικό άνδρα, συγγραφέα, ιεροκήρυκα και δάσκαλο εκ των επιφανών Ελλήνων λογίων του 18ου αι. Αρχικά, παρουσιάζεται η βιογραφία του, οι σπουδές του στην Ζάκυνθο και στη συνέχεια στο Παπικό Κολλέγιο της Ρώμης. Έπειτα σημειώνεται ο ερχομός του στη Βενετία αλλά και το διδασκαλικό και ιεροκηρυκτικό του έργο στην Ελληνική Αδελφότητα. Ακολουθεί το κεφάλαιο για τη Φλαγγίνειο Σχολή στην οποία δίδαξε στη πορεία της ζωής του αλλά και τα μεθεπόμενα κεφάλαια που αφορούν την Μητρόπολη Φιλαδελφείας, στην οποία ο Κατήφορος είχε θέσει υποψηφιότητα για τη θέση του τοποτηρητή και το κεφάλαιο για τον Άγιο Γεώργιο των Ελλήνων, στον οποίο υπηρέτησε ως εφημέριος αλλά και ως ιεροκήρυκας. Από τις πιο ενδιαφέρουσες πτυχές του Αντωνίου Κατήφορου είναι η σχέση του με τον Τεκτονισμό (Μασονία). Στην συνέχεια παρουσιάζεται η εργογραφία του Κατήφορου, δηλ. η Ελληνική Γραμματική, ο βίος του Μ. Πέτρου, η Ιερά Ιστορία της Παλαιάς και Νέας Διαθήκης αλλά και το ανέκδοτο έργο του με την μετάφρασή του στην λατινική για το σχολιασμό του έργου του Φωτίου. Τέλος, η μελέτη κλείνει με κρίσεις παλαιών λογίων για την προσωπικότητα του Αντώνιου Κατήφορου και την μονογραφία της Margherita Losacco για τον Κατήφορο
description: The subject of this diploma thesis concerns the Zakynthian scholar Antonios Katiforos (1685-1763). He is an ecclesiastic man, writer, preacher and teacher of the 18th century. Initially, his biography and his studies in Zakynthos are presented and then subsequently in the Popish College of Rome. Then his advent to Venice is noted and also his teaching and preaching work in the Greek Brotherhood. This is followed by the chapter of the Flagginos School in which he taught his life course, as well as the remaining chapters concerning the Philadelphia Metropolis, in which Katiforos was nominated for the position of the observer and chapter on St. George of the Greeks, where he served as a vicar also as preacher. One of the most interesting aspects of Antonios Katiforos is his relationship with the Tectonics (Masonia). Following this is the workshop of Katiforos, e.g the Greek Grammar, the life of Grand Peter, the Holy History of the Old and New Testaments, and his unpublished work with his translation into Latin for the commentary of Fotios work. Finally, the study ends with judgments of old scholars on the personality of Antonios Katiforos and Margherita Losacco’s monophysiology of Katiforos

Leptogenesis, Fermion Masses and Mixings in a SUSY $SU(5)$ GUT with $D_{4}$ Flavor Symmetry
Creators: name: Miskaoui, M.
name: Loualidi, M. A.
Publisher: name: arXiv
Year: 2021
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We propose a model of fermion masses and mixings based on $SU(5)$ grand unified theory (GUT) and a $D_{4}$ flavor symmetry. This is a highly predictive 4D $SU(5)$ GUT with a flavor symmetry that does not contain a triplet irreducible representation. The Yukawa matrices of quarks and charged leptons are obtained after integrating out heavy messenger fields from renormalizable superpotentials while neutrino masses originate from the type I seesaw mechanism. The group theoretical factors from 24- and 45-dimensional Higgs fields lead to ratios between the Yukawa couplings in agreement with data, while the dangerous proton decay operators are highly suppressed. By performing a numerical fit, we find that the model captures accurately the mixing angles, the Yukawa couplings and the $CP$ phase of the quark sector at the GUT scale. The neutrino masses are generated at the renormalizable level with the prediction of trimaximal mixing while an additional effective operator is required to account for the baryon asymmetry of the universe (BAU). The model is remarkably predictive because only the normal neutrino mass ordering and the lower octant of the atmospheric angle are allowed while the $CP$ conserving values of the Dirac neutrino phase $δ_{CP}$ are excluded. Moreover, the predicted values of the effective Majorana mass $m_{ββ}$ can be tested at future neutrinoless double beta decay experiments. An analytical and a numerical study of the BAU via the leptogenesis mechanism is performed. We focused on the regions of parameter space where leptogenesis from the lightest right-handed neutrino is successfully realized. Strong correlations between the parameters of the neutrino sector and the observed BAU are obtained.

Tracking Vector Magnetograms with the Magnetic Induction Equation
Creators: name: Schuck, P. W.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The differential affine velocity estimator (DAVE) developed in Schuck (2006) for estimating velocities from line-of-sight magnetograms is modified to directly incorporate horizontal magnetic fields to produce a differential affine velocity estimator for vector magnetograms (DAVE4VM). The DAVE4VM's performance is demonstrated on the synthetic data from the anelastic pseudospectral ANMHD simulations that were used in the recent comparison of velocity inversion techniques by Welsch (2007). The DAVE4VM predicts roughly 95% of the helicity rate and 75% of the power transmitted through the simulation slice. Inter-comparison between DAVE4VM and DAVE and further analysis of the DAVE method demonstrates that line-of-sight tracking methods capture the shearing motion of magnetic footpoints but are insensitive to flux emergence -- the velocities determined from line-of-sight methods are more consistent with horizontal plasma velocities than with flux transport velocities. These results suggest that previous studies that rely on velocities determined from line-of-sight methods such as the DAVE or local correlation tracking may substantially misrepresent the total helicity rates and power through the photosphere.

description: We study the persistent currents and interspecies entanglement generation in a Bose-Bose mixture formed by two atomic gases (hereafter labelled by the letters A and B) trapped in a one-dimensional ring lattice potential with an artificial gauge field after a sudden quench from zero to strong interactions between the two gases. Assuming that the strength of these interactions is much larger than the single species energies and that the gas A is initially in the Mott-insulator regime, we show that the current of the gas B is reduced with respect to its value prior the interaction quench. Averaging fast oscillations out, the relative decrease of this current is independent of the initial visibility and Peierls phase of the gas B and behaves quadratically with the visibility of the gas A. The second Rényi entropy of the reduced state measuring the amount of entanglement between the two gases is found to scale linearly with the number of sites and to be proportional to the relative decrease of the current.

Realistic triaxial density--potential--force profiles for stellar systems and dark matter halos
Creators: name: Terzic, Balsa
name: Sprague, Benjamin J.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: Popular models for describing the luminosity-density profiles of dynamically hot stellar systems (e.g., Jaffe, Hernquist, Dehnen) were constructed to match the deprojected form of de Vaucouleurs' $R^{1/4}$ light-profile. However, we now know that elliptical galaxies and bulges display a mass-dependent range of structural profiles. To compensate this, the model in Terzic & Graham was designed to closely match the deprojected form of Sersic $R^{1/n}$ light-profiles, including deprojected exponential light-profiles and galaxies with partially depleted cores. It is thus applicable for describing bulges in spiral galaxies, dwarf elliptical galaxies, both ``power-law'' and ``core'' elliptical galaxies, also dark matter halos formed from $Λ$CDM cosmological simulations. In this paper, we present a new family of triaxial density-potential-force triplets, which generalizes the spherical model reported in Terzic & Graham to three dimensions. If the (optional) power-law core is present, it is a 5-parameter family, while in the absence of the core it reduces to 3 parameters. The isodensity contours in the new family are stratified on confocal ellipsoids and the potential and forces are expressed in terms of integrals which are easy to evaluate numerically. We provide the community with a suite of numerical routines for orbit integration, which feature: optimized computations of potential and forces for this family; the ability to run simulations on parallel platforms; and modular and easily editable design.

description: We report $J^π= 0^+$ ground-state energies and point-proton radii of $^4$He, $^8$Be, $^{12}$C, $^{16}$O and $^{20}$Ne nuclei calculated by the $ab$ $initio$ no-core Monte Carlo shell model with the JISP16 and Daejeon16 nonlocal $NN$ interactions. Ground-state energies are obtained in the basis spaces up to seven oscillator shells ($N_{\rm shell} = 7$) with several oscillator energies ($\hbar ω$) around the optimal oscillator energy for the convergence of ground-state energies. These energy eigenvalues are extrapolated to obtain estimates of converged ground state energies in each basis space using energy variances of computed energy eigenvalues. We further extrapolate these energy-variance-extrapolated energies obtained in the finite basis spaces to infinite basis-space results with an empirical exponential form. This form features a dependence on the basis-space size but is independent of the value of $\hbarω$ used for the harmonic-oscillator basis functions. Point-proton radii for these states of atomic nuclei are also calculated following techniques employed for the energies. From these results, it is found that the Daejeon16 $NN$ interaction provides good agreement with experimental data up to approximately $^{16}$O, while the JISP16 $NN$ interaction provides good agreement with experimental data up to approximately $^{12}$C. Beyond these nuclei, the interactions produce overbinding accompanied by radii that are too small. These findings suggest and encourage further revisions of nonlocal $NN$ interactions towards the investigation of nuclear structure in heavier-mass regions.

Transforming student perceptions: the Casa Guatemala experience
Creators: name: Stewart, Jeffrey Todd
Publisher: name: University of British Columbia
Year: 2009

description: Teaching students to have a “global perspective” is one of the key aspects of global education. Curriculum used to develop such a perspective at the high school level rarely involves experiential cross-cultural programs which take students to the “Third World”. One such program, the Casa Guatemala Project in British Columbia’s Richmond School District, sends a small group of grade eleven and twelve students to Guatemala each year for two weeks to work at a childrens’ orphanage. This study looks at how the experience transforms the students’ perceptions of Guatemala, North America and themselves. This investigation focuses on the substance and dynamics of changes in the students’ perceptions using Mezirow’s (1991) theory of the transformative dimensions of adult learning. The research follows six students as they go through the program from September of 1992 to April of 1993. Semi-structured and open-ended interviews, student journals, researcher observations and available documentation suggest that the students’ perceptions and worldview are altered as a result of three key dynamics: a) conflict and dilemma, b) selective perception, and C) group dynamics and dialogue. When the students return to Canada they experience an intense period of alienation from their own community and society as they attempt to comprehend, assimilate and accommodate solutions to new understandings generated by the experience. The possible benefits of structured preparation and debriefing sessions are explored, as are implications for other experiential learning programs of a similar nature.

Temperature dependent Raman experiments show up to five resonant enhancements of the 2-magnon excitation below the Neel temperature. These are shown to be collective interactions between on-site Fe d-d electronic resonance, phonons and multimagnons

description: In the present work, two machine learning based constitutive models for finite deformations are proposed. Using input convex neural networks, the models are hyperelastic, anisotropic and fulfill the polyconvexity condition, which implies ellipticity and thus ensures material stability. The first constitutive model is based on a set of polyconvex, anisotropic and objective invariants. The second approach is formulated in terms of the deformation gradient, its cofactor and determinant, uses group symmetrization to fulfill the material symmetry condition, and data augmentation to fulfill objectivity approximately. The extension of the dataset for the data augmentation approach is based on mechanical considerations and does not require additional experimental or simulation data. The models are calibrated with highly challenging simulation data of cubic lattice metamaterials, including finite deformations and lattice instabilities. A moderate amount of calibration data is used, based on deformations which are commonly applied in experimental investigations. While the invariant-based model shows drawbacks for several deformation modes, the model based on the deformation gradient alone is able to reproduce and predict the effective material behavior very well and exhibits excellent generalization capabilities. In addition, the models are calibrated with transversely isotropic data, generated with an analytical polyconvex potential. For this case, both models show excellent results, demonstrating the straightforward applicability of the polyconvex neural network constitutive models to other symmetry groups.

description: The superselection sectors of two classes of scalar bilocal quantum fields in D>=4 dimensions are explicitly determined by working out the constraints imposed by unitarity. The resulting classification in terms of the dual of the respective gauge groups U(N) and O(N) confirms the expectations based on general results obtained in the framework of local nets in algebraic quantum field theory, but the approach using standard Lie algebra methods rather than abstract duality theory is complementary. The result indicates that one does not lose interesting models if one postulates the absence of scalar fields of dimension D-2 in models with global conformal invariance. Another remarkable outcome is the observation that, with an appropriate choice of the Hamiltonian, a Lie algebra embedded into the associative algebra of observables completely fixes the representation theory.

description: Στην εργασία αυτή, παρουσιάσαμε την θρησκευτικότητα στο έργο του Βιντσέντζου Κορνάρου. Αρχικά, αναφερθήκαμε στην κρητική αναγέννηση και το ποιμενικό ειδύλλιο που χαρακτήριζε την εποχή της Αναγέννησης. Μελετήσαμε τις λογοτεχνικές λέσχες, καθώς και τις επαφές της Κρήτης με την Βενετία, ενώ επισημάναμε τα αντιπροσωπευτικά έργα της ποιμενικής ποίησης δηλαδή την κωμωδία Πανώρια του Χορτάτση, και το ποιητικό ειδύλλιο τη Βοσκοπούλα. Στη συνέχεια, αναφέραμε τον ποιητή του Ερωτόκριτου και την καταγωγή του, καθώς και αναλύσαμε τι σημαίνει θρησκευτικό δράμα. Επίσης, αναλύσαμε το έργο η Θυσία του Αβραάμ αν είναι θρησκευτικό μυστήριο ή θεατρικό έργο ενώ επισημάναμε και την παρέλευση του χρόνου. Αυτό που ήταν σημαντικότερο ήταν οι εκτενείς αναφορές στον Θεό καθώς και ποιες αλλαγές έγιναν με σκοπό τους θρησκευτικούς λόγους. Τέλος, αναφέραμε την επίδραση της Θυσίας του Αβραάμ σε άλλα έργα καθώς και την απήχησή του στον ελληνικό λαό
description: In this work, we presented religiousness in the work of Vincentzos Kornaros. Initially, we referred to the Cretan Renaissance and the pastoral romance that characterized the Renaissance. We studied the literary clubs, as well as the contacts of Crete with Venice, while highlighting the representative works of pastoral poetry, namely the comedy Poriaa of Hortatsi, and the poetic romance of Voskopoula. Then we mentioned the poet's poet and his origins, as well as we analyzed what religious drama means. We also analyzed the work of the Sacrifice of Abraham if it is a religious mystery or a play, while we also pointed out the passing of time. What was most important was the extensive references to God as well as what changes were made for religious reasons. Finally, we mentioned the effect of Abraham's Sacrifice on other works as well as his effect on the Greek people

description: Under holographic prescription for Schwinger-Keldysh closed time contour for non-equilibrium system, we consider fluctuation effect of the order parameter in a holographic superconductor model. Near the critical point, we derive the time-dependent Ginzburg-Landau effective action governing dynamics of the fluctuating order parameter. In a semi-analytical approach, the time-dependent Ginzburg-Landau action is computed up to quartic order of the fluctuating order parameter, and first order in time derivative.

description: Σκοπός της διατριβής ήταν η μελέτη ενός εκκλησιαστικού ιστορικού προσώπου, του Καλλινίκου Καστόρχη, ο οποίος διετέλεσε Αρχιεπίσκοπος Φθιώτιδος και Λοκρίδος από το 1852 έως 1877. Ο Καλλίνικος διαδραμάτισε σημαντικό ρόλο πριν την επανάσταση του 1821, κατά τη διάρκεια αυτής αλλά και μετά απ’ αυτή. Στη συνέχεια, εξετάστηκαν τα ιστορικά στοιχεία της περιόδου και της περιοχής καθώς και η εκκλησιαστική κατάσταση στη Φθιώτιδα κατά την έναρξη της επανάστασης. Ακόμη, παρατέθηκαν βιογραφικά στοιχεία και τα σχετικά με την περίοδο της αρχιερατείας του. Ένα άλλο θέμα που θίξαμε ήταν η εθνική προσφορά του ως διδάσκαλος της σχολής Δημητσάνας, τη σχέση του με τον Νικόλαο Μακρή και την αναστήλωση της σχολής και του ναού της Αγίας Κυριακής. Ασχοληθήκαμε επίσης με τους διορισμούς του σε διάφορες θέσεις και με τη σχέση του με τον κυβερνήτη Ιωάννη Καποδίστρια. Αναφέρεται η εκκλησιαστική κατάσταση στην Ελλάδα κατά την περίοδο της αρχιερατείας του και ο τρόπος εκλογής του. Επίσης, περιγράφονται οι αποστολές που του ανατέθηκαν από την εκκλησία και την πολιτεία τις οποίες κι έφερε εις πέρας, ενώ μας απασχόλησε το συγγραφικό και ποιμαντικό του έργο, τα σχετικά με το θάνατο και την ταφή του καθώς και η αλληλογραφία με διάφορα σημαντικά πρόσωπα της εποχής
description: The purpose of this thesis was to study an ecclesiastical historical figure, Kallinikos Kastrochris Archbishop of Fthiotis and Lokris from 1852 to 1877. Kallinikos played an important role in the 1821 revolution, both and and afterwards. Furthermore, the historical elements of the period and region were examined, as well as the ecclesiastical situation in Fthiotida at the beginning of the revolution. Biographical data related to the period of his Bishopric were also provided. Another issue that we touched upon was his National Contribution as a teacher of the Dimitsana School, his relationship with Nicholas Makris and the restoration of the church of Saint Kyriaki. We also dealt with his appointments in various positions and his relationship with the governor Ioannis Kapodistrias. The ecclesiastical situation in Greece during the period of his Bishopric and the way of his election is also mentioned. Also described are the missions carried out by the church and the state, engaging also with his writing and pastoral work, related articles to his death and his burial and correspondence with various important persons of the time

description: Είναι γεγονός πως η δερματοστιξία αποτελεί μία πανάρχαια πρακτική, η οποία εφαρμοζόταν σε όλους σχεδόν τους γνωστούς πολιτισμούς της αρχαιότητας, κατά μήκος όλων των ηπείρων και θεωρείτο αναπόσπαστο στοιχείο της πολιτιστικής τους ταυτότητας. Παρόλα αυτά, η δερματοστιξία στον σύγχρονο κόσμο και πολιτισμό διαδόθηκε κατά την περίοδο του Διαφωτισμού. Σε όλον τον κόσμο πλέον το τατουάζ θεωρείται, από πολλούς, μορφή τέχνης, αλλά επιπλέον επιβάλλεται, όλο και περισσότερο, ως ένα είδος μόδας, φαινόμενο που, όχι μόνο δε μειώνεται, αλλά σταδιακά αυξάνεται, αφού η πρακτική κερδίζει συνέχεια νέους οπαδούς. Από θεολογικής πλευράς, το ανθρώπινο σώμα θεωρείται ιερό, καθώς αποτελεί τον ναό του Θεού, στον οποίο κατοικεί το Άγιο Πνεύμα. Όλη η Δημιουργία, άρα και το σώμα, έχει δημιουργηθεί από τον Θεό «καλώς» και δεν ανήκει σε εμάς, αλλά σε Αυτόν, γεγονός που σημαίνει πως δεν μας επιτρέπεται να το μεταχειριζόμαστε κατά το δοκούν και να το μεταβάλλουμε. Λαμβάνοντας υπόψιν μας αυτά, θα μπορούσαμε κάλλιστα να πούμε πως οποιαδήποτε προσπάθεια μετατροπής και τροποποίησης του σώματος κρίνεται θεολογικά μη αποδεκτή. Θα μπορούσε η αγάπη του Θεού για τον άνθρωπο να συγχωρήσει τέτοιου είδους σφάλματα; Επίσης, θα μπορούσε η Χριστιανική Ηθική, χάριν Οικονομίας, να αποδεχθεί τέτοιου είδους πρακτικές, εάν αυτές δεν πηγάζουν από πάθη, όπως η ματαιοδοξία και ο εγωισμός; Σε αυτού του είδους τις ερωτήσεις θα επιχειρήσει να δώσει απαντήσεις η εργασία αυτή.
description: Tattooing is being practiced since ancient times by many cultures all over the world and even more it was considered to be an integral part of their cultural identity. However, this practice in the modern world and culture was spread throughout the Enlightenment period. Nowadays, tattooing is widely regarded as a form of art, but it is becoming also more and more a form of fashion, a phenomenon that not only decreases but gradually increases, as the practice is constantly gaining new fans. Theologically speaking, the human body is something sacred, since it is the temple of God in which the Holy Spirit resides. Everything, ergo the body as well, has been created "very good" and it is not our possession but God's, thus the man is not allowed to treat it as he pleases let alone distort it. Taking into account this teaching, we could easily say that any attempt to modify the body is determined as theologically unacceptable. Does God's love and caress for humankind mean that He could forgive such mistakes? Besides that, are Christian Ethics willing to consider such practices acceptable if they do not come from passions like vanity and egoism? These are the kind of questions this dissertation will attempt to answer to.

description: In molecular dynamics (MD), neural network (NN) potentials trained bottom-up on quantum mechanical data have seen tremendous success recently. Top-down approaches that learn NN potentials directly from experimental data have received less attention, typically facing numerical and computational challenges when backpropagating through MD simulations. We present the Differentiable Trajectory Reweighting (DiffTRe) method, which bypasses differentiation through the MD simulation for time-independent observables. Leveraging thermodynamic perturbation theory, we avoid exploding gradients and achieve around 2 orders of magnitude speed-up in gradient computation for top-down learning. We show effectiveness of DiffTRe in learning NN potentials for an atomistic model of diamond and a coarse-grained model of water based on diverse experimental observables including thermodynamic, structural and mechanical properties. Importantly, DiffTRe also generalizes bottom-up structural coarse-graining methods such as iterative Boltzmann inversion to arbitrary potentials. The presented method constitutes an important milestone towards enriching NN potentials with experimental data, particularly when accurate bottom-up data is unavailable.

A cross sectional analysis of air pollution’s impact of chronic respiratory disease in Ontario

description: Does ambient air pollution in Canada pose a threat to respiratory health? For a study initiated by Health Canada, we combined analyses of micro-level data from both the 1990 Ontario Health Survey with an environmental air monitoring system to obtain a quantitative answer to the question. In contrast to studies designed to collect special purpose data, the Ontario Health Survey was not designed to address respiratory health issues. In spite of this, this cross sectional database was rich enough for modelling. We used asthma and emphysema as the response variables in assessing the impact of four pollutants estimated for summer and winter. Two analyses were conducted for each response variable, one incorporating survey de sign information the other ignoring it. Age, income, smoker type and sex were significantly related to asthma at a a = 5% level of confidence in both analyses. None of the pollutant covariates figured in the model. Using the classical x2 test for nested models as the criterion, the emphysema model achieved a better fit than the asthma model. Smoker type and age, in particular, were strongly related to emphysema; income and number of cigarettes smoked were significantly but less strongly related; summer N2O was marginally significant, depending on which of the two analyses was considered.

description: The Statistical Model has to be formulated in the canonical ensemble with respect to strangeness conservation if the number of strange particles becomes small. However, the canonical suppression under the assumption of strangeness chemical equilibrium in the whole fireball volume was found to be not sufficient to reproduce observed yields. Two approaches have been proposed to modify the model. First, a non-equilibrium factor was introduced in canonical and grand-canonical ensembles as the additional fit parameter to account for the suppressed strange particle phase-space. Here we focus on the second method: The model is extended by correlation volumes which restrict the strangeness chemical equilibrium only to certain subvolumes of the system.
