description: In this paper, we find the energy-momentum distribution of stationary axisymmetric spacetimes in the context of teleparallel theory by using M$\ddot{o}$ller prescription. The metric under consideration is the generalization of the Weyl metrics called the Lewis-Papapetrou metric. The class of stationary axisymmetric solutions of the Einstein field equations has been studied by Galtsov to include the gravitational effect of an {\it external} source. Such spacetimes are also astrophysically important as they describe the exterior of a body in equilibrium. The energy density turns out to be non-vanishing and well-defined and the momentum becomes constant except along $θ$-direction. It is interesting to mention that the results reduce to the already available results for the Weyl metrics when we take $ω=0$.

description: We study all the possible spin asymmetries that can arise in back-to-back electron-jet production, $ep\rightarrow e+\text{jet}+X$, as well as the associated jet fragmentation process, $ep\rightarrow e+ \text{jet} (h)+X$, in electron-proton collisions. We derive the factorization formalism for these spin asymmetries and perform the corresponding phenomenology for the kinematics relevant to the future electron ion collider. In the case of unpolarized electron-proton scattering, we also give predictions for azimuthal asymmetries for the HERA experiment. This demonstrates that electron-jet production is an outstanding process for probing unpolarized and polarized transverse momentum dependent parton distribution functions and fragmentation functions.

Quantification and timing of processes involved in stimulus-secretion coupling at the mouse neuromuscular junction
Creators: name: Bain, Allen Ian
Publisher: name: University of British Columbia
Year: 2009

description: At the mammalian neuromuscular junction, perhaps the most studied synapse, many aspects of neurotransmitter release and stimulation-induced enhancement of release are still poorly understood. Central hypotheses include: about release, the Ca²⁺ hypothesis (del Castillo and Katz, 1954), and the Ca²⁺-voltage hypothesis (Parnas and Parnas, 1988), and about enhancement, the residual Ca²⁺ hypothesis (Katz & Miledi, 1968). In the present work, these hypotheses were tested by analysis of the magnitude and timing of release with the technical advantages of computer-assisted analysis of data for large numbers of stimuli and responses and an emphasis on the relative magnitude of phasic and non-phasic release components. In mouse nerve-diaphragm in vitro, phasic neurotransmitter release evoked by action potentials grew with r«0.1 ms and decayed with r«0.3 ms, consistent for Ca²⁺, Sr²⁺ and Ba²⁺. Non-phasic release decayed, with a polyphasic time course that varied with the divalent cation. The time course of the opening of voltage-dependent presynaptic divalent cation channels underlying the release process was assessed using "tails" of raised MEPP frequency induced by trains of "direct" pulses (TTX present) in Ba²⁺- containing solution. Pulses exceeding 50 ms duration were nearly equi-effective (by integral) to more brief pulses,indicating that this Ca²⁺ channel undergoes little inactivation. In the presence of Sr²⁺ or Ba²⁺, short term stimulation-induced enhancement of release was consistent with a simple "residual ion" model, with 'cooperativity' of 4, and decay of putative intracellular ion with r«200 ms or r«3 to 5s, respectively. In Ca²⁺, facilitation (short term enhancement) was inconsistent with a residual ion model but could be resolved into two components: a multiplicative component seen as an about two-fold parallel increase in m and fm for short trains (decay r«80 ms), dependent on intracellular Ca²⁺ and Ca²⁺ influx, plus an additive component (decay r«200 ms) consistent with the residual ion model. Potentiation (long term enhancement) was found to consist primarily in parallel of a parallel multiplication of phasic and non-phasic release with r<20 s. It was absent when tetrodotoxin was present ('direct' stimulation), suggesting dependence upon Na+ influx and accumulation. With prolonged tetani, non-phasic release increased further, in a manner consistent with gradually accumulating Ca²⁺.
q-Deformed su(2) instantons by q-quaternions

description: Interpreting the coordinates of the quantum Euclidean space R_q^4 [the SO_q(4)-covariant noncommutative space] as the entries of a ``q-quaternion matrix'' we construct (anti)instanton solutions of a would-be q-deformed su(2) Yang-Mills theory on R_q^4. Since the (anti)selfduality equations are covariant under the quantum group of deformed rotations, translations and scale change, by applying the latter we can respectively generate ``gauge equivalent'' or ``inequivalent'' solutions from the one centered at the origin and with unit size. We also construct multi-instanton solutions. As these solutions depend on noncommuting parameters playing the roles of `sizes' and `coordinates of the centers' of the instantons, this indicates that the moduli space of a complete theory should be a noncommutative manifold. Similarly, as the (global) gauge transformations relating ``gauge equivalent'' solutions depend on the generators of two copies of SU_q(2), this suggests that gauge transformations should be allowed to depend on additional noncommutative parameters.

description: We investigate the attenuation law in $z\sim 6$ quasars by combining cosmological zoom-in hydrodynamical simulations of quasar host galaxies, with multi-frequency radiative transfer calculations. We consider several dust models differing in terms of grain size distributions, dust mass and chemical composition, and compare the resulting synthetic Spectral Energy Distributions (SEDs) with data from bright, early quasars. We show that only dust models with grain size distributions in which small grains ($a < 0.1~μ$m, corresponding to $\approx 60\%$ of the total dust mass) are selectively removed from the dusty medium provide a good fit to the data. Removal can occur if small grains are efficiently destroyed in quasar environments and/or early dust production preferentially results in large grains. Attenuation curves for these models are close to flat, and consistent with recent data; they correspond to an effective dust-to-metal ratio $f_d \simeq 0.38$, i.e. close to the Milky Way value.

description: The software engineering industry is aware that bad design decisions have a negative impact on the software life cycle. Code smells, one of the symptoms of these wrong decisions, have been the focus of a great number of both academic and industrial research. There are, though, some bad decisions, which can occur at a higher level of abstraction, that could lead to even more dreadful effects: these are called architectural smells. Architectural smells have received way less attention than code smells even if they are usually considered more critical and harder to detect, remove, and refactor. However, both academia and industry proposed some tools aiming at detecting these flaws, but most of them are under a commercial license. Therefore, to overcome this obstacle that prevents researchers from deepening their comprehension of these problems, in this article, we present a novel open-source architectural smell detection tool, named BRUNELLESCHI The tool can detect three types of smells at different levels of granularity, namely Cyclic Dependency, Hub-Like Dependency, and Unstable Dependency. Results of a preliminary evaluation show that the proposed tool is able to achieve a precision of 100%.

description: Bing doubling is an operation which produces a 2-component boundary link B(K) from a knot K. If K is slice, then B(K) is easily seen to be boundary slice. In this paper, we investigate whether the converse holds. Our main result is that if B(K) is boundary slice, then K is algebraically slice. We also show that the Rasmussen invariant can tell that certain Bing doubles are not smoothly slice.

Το δείγμα αποτέλεσαν 55 παιδιά της Β' τάξης ενός Δημοτικού Σχολείου αστικής περιοχής. Τα παιδιά χωρίστηκαν σε δύο ομάδες, την Πειραματική που δέχτηκε παρέμβαση με παιχνίδια για δέκα εβδομάδες και την Ελέγχου που δε δέχτηκε καμία παρέμβαση. Η δημιουργικότητα αξιολογήθηκε ως προς τις παραμέτρους ευχέρεια, πρωτοτυπία και φαντασία, μέσω της δοκιμής ΤCΑΜ (Thinking Creatively in Action and Movement) του Torrance (1981). Για τη μέτρηση των Θετικών και Αρνητικών Συναισθημάτων, χρησιμοποιήθηκε η Κλίμακα Θετικής και Αρνητικής Συναισθηματικής Κατάστασης, Positive and Negative Affect Scale (Watson, Clark, & Tellegen, 1988 b, PANAS). Τα αποτελέσματα έδειξαν ότι τα παιδιά που συμμετείχαν στα παιχνίδια παρουσίασαν αυξημένες τιμές στους παράγοντες της δημιουργικότητας. Ως προς τα συναισθήματα, διατηρήθηκαν οι τιμές στα θετικά και μειώθηκαν τα αρνητικά για τα παιδιά της Πειραματικής Ομάδας, μετά το τέλος του προγράμματος.
description: The purpose of this study is to investigate the effect of Playing as a Psychomotor education medium, on feelings and the development of creativity in primary school age children (7-8 years). The case study consisted of 55 children attending the second year of an urban elementary school. The children were divided into two groups, the Experimental that received games intervention for ten weeks and the Control who did not accept any intervention. The creativity was evaluated based on ability, originality and imagination parameters, through 1981 Torrance TCAM test (Thinking Creatively in Action and Movement).The Scale of Positive and Negative Emotional Status was used to measure the Positive and Negative Emotions, Positive and Negative Affect Scale (PANAS) by Watson, Clark and Tellegen (1988 b). The results showed that children who participated in the games showed increased values in creativity factors. As for emotions, kept prices on the positive and negative decreased for children of the Experimental Group, after the end of the program.

Semiclassical approach to Bose-Einstein condensates in a triple well potential

description: We present a new approach for the analysis of Bose-Einstein condensates in a few mode approximation. This method has already been used to successfully analyze the vibrational modes in various molecular systems and offers a new perspective on the dynamics in many particle bosonic systems. We discuss a system consisting of a Bose-Einstein condensate in a triple well potential. Such systems correspond to classical Hamiltonian systems with three degrees of freedom. The semiclassical approach allows a simple visualization of the eigenstates of the quantum system referring to the underlying classical dynamics. From this classification we can read off the dynamical properties of the eigenstates such as particle exchange between the wells and entanglement without further calculations. In addition, this approach offers new insights into the validity of the mean-field description of the many particle system by the Gross-Pitaevskii equation, since we make use of exactly this correspondence in our semiclassical analysis. We choose a three mode system in order to visualize it easily and, moreover, to have a sufficiently interesting structure, although the method can also be extended to higher dimensional systems.

description: A growing number of eclipsing binary systems of the "HW Vir" kind (i. e., composed by a subdwarf-B/O primary star and an M dwarf secondary) show variations in their orbital period, also called Eclipse Time Variations (ETVs). Their physical origin is not yet known with certainty: while some ETVs have been claimed to arise from dynamical perturbations due to the presence of circumbinary planetary companions, other authors suggest that the Applegate effect or other unknown stellar mechanisms could be responsible for them. In this work, we present twenty-eight unpublished high-precision light curves of one of the most controversial of these systems, the prototype HW Virginis. We homogeneously analysed the new eclipse timings together with historical data obtained between 1983 and 2012, demonstrating that the planetary models previously claimed do not fit the new photometric data, besides being dynamically unstable. In an effort to find a new model able to fit all the available data, we developed a new approach based on a global-search genetic algorithm and eventually found two new distinct families of solutions that fit the observed timings very well, yet dynamically unstable at the 10^5-year time scale. This serves as a cautionary tale on the existence of formal solutions that apparently explain ETVs but are not physically meaningful, and on the need of carefully testing their stability. On the other hand, our data confirm the presence of an ETV on HW Vir that known stellar mechanisms are unable to explain, pushing towards further observing and modelling efforts.

description: The free energies of six-vertex models on general domain D with various boundary conditions are investigated with the use of the n-equivalence relation which classifies the thermodynamic limit properties. It is derived that the free energy of the six-vertex model on the rectangle is unique in the limit in which both the height and the width goes to infinity. It is derived that the free energies of the model on D are classified through the densities of left/down arrows on the boundary. Specifically the free energy is identical to that obtained by Lieb and Sutherland with the cyclic boundary condition when the densities are both equal to 1/2. This fact explains several results already obtained through the transfer matrix calculations. The relation to the domino tiling (or dimer, or matching) problems is also noted.

description: Charney and DeVore [J. Atmos. Sci. 36 (1979), 1205-1216] found multiple equilibrium states as a consequence of bottom topography in their pioneering work on the quasi-geostrophic barotropic flow over topography in a $β$-plane channel. In the present paper, we prove that the basic flow is asymptotically stable in a parameter region, including the flat topography situation, which excludes the existence of multiple equilibrium states therein. Moreover, we show that an additional condition on the average zonal force or the average zonal velocity is indispensable to the well-posedness of the Charney-DeVore quasi-geostrophic equation. Coexistence of at least three equilibrium states is confirmed by a pseudo-arclength continuation method for different topographic amplitudes. The stabilities of the equilibrium states are examined by high-resolution direct numerical simulations.
Ring road development and vacant lands Riyadh, Saudi Arabia
Creators: name: Alskait, Khalid
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation is concerned with the relationship between freeway development and the pattern of urban development. In particular, this research examines whether there is any relationship between ring road development and the proliferation of vacant urban lands in Riyadh, Saudi Arabia. The main hypothesis of this dissertation suggests that the development of ring roads, at a time when a substantial amount of inner lands are vacant, encourages leapfrogging growth, thus creating more vacant urban lands. Both primary data and existing data, collected by governmental agencies, were collected and analyzed. Primary data were collected using a questionnaire survey. The survey included interviews with relevant public officials, private developers, and academics. One hundred people were approached to complete the questionnaire, and seventy-six of them responded. The primary existing data source was the Arriyadh Development Authority (ADA). The ADA provided land use data for 1986-87 and 1990-91. These data included relevant urban variables (including land use variables, population variables, dwelling unit variables) for sixteen submunicipalities in Riyadh. The analyses of land use data were supplemented by an analysis of aerial images of the city which had been taken before and after the development of the ring road, sections of which were opened in 1984 and 1986. The interviews, the land use data, and the aerial images were complementary to each other in the analysis. The findings of this dissertation suggest that there is a correlation between the development of the Riyadh Ring Road and the size and distribution of current vacant urban lands. This confirms the main hypothesis. It is suggested that the timing of ring road development is critical to the increase in the amount of vacant urban lands. In order to avoid and/or to decrease such an increase in vacant lands, ring roads should be developed only after a certain percentage of the lands within the urban area have been developed. If more vacant urban lands exist at the time of the development of a ring road, then more leapfrogging growth will occur. This type of growth will result in more vacant urban lands and will stretch the city in all directions, thus reducing efficiency.

description: Local polarization effects, induced by mono and divalent positive ions in water, influence (and in turn are influenced by) the large scale structural properties of the solvent. Experiments can only distinguish this process of interplay in a generic qualitative way. Instead, first principles quantum calculations can address the question at both electronic and atomistic scale, accounting for electronic polarization as well as geometrical conformations. For this reason we study the extension of the scales' interconnection by means of first principle Car-Parrinello molecular dynamics applied to systems of different size. In this way we identify the general aspects dominating the physics of the first solvation shell and their connection to the effects related to the formation of the outer shells and eventually the bulk. We show that while the influence of the ions is extended to the first shell only, the water-water interaction is instead playing a dominant role even within the first shell independently from the size or the charge of the ion.

description: In the present work we propose a method to determine fluctuation induced forces in non equilibrium systems. These forces are the analogue of the well known Casimir forces, which were originally introduced in Quantum Field theory and later extended to the area of Critical Phenomena. The procedure starts from the observation that many non equilibrium systems exhibit long-range correlations and the associated structure factors diverge in the long wavelength limit. The introduction of external bodies into such systems in general modifies the spectrum of these fluctuations and leads to the appearance of a net force between these bodies. The mechanism is illustrated by means of a simple example: a reaction diffusion equation with random noises.

description: The dictatorship of April 21, 1967 was one of the many military regimes imposed on Greece during the last century. This paper aims to present the ideological direction had that status by analyzing the concepts of nationalism and populism.These are two concepts that have strongly occupied the scientific community, as there is a plethora of definitions around them, without the scientific community has come up with an acceptable by all definitions. The first chapter was devoted to the exposition of the definitions given by influential scholars of these phenomena. Then, reference was made in political discourse that emanated from Colonels Papadopoulos and Lada, and the next two chapters of the work devoted to those who tried to shoulder the role of the ideological representative of the colonels' regime. In the end, they exported some conclusions about the nature of the scheme based on the combination of theoretical framework with empirical material.

Using a spectrum of AZ Cyg obtained with SpeX on the NASA InfraRed Telescope Facility (IRTF) and synthetic spectra calculated from spherical MARCS, spherical PHOENIX, and SAtlas model atmospheres, we derive $T_{\text{eff}}$ is between $3972 K$ and $4000 K$ and $\log~g$ between $-0.50$ and $0.00$, depending on the stellar model used. Using fits to the squared visibility and Gaia parallaxes we measure its average radius $R=911^{+57}_{-50}~R_{\odot}$. Reconstructions of the stellar surface using our model-independent imaging codes SQUEEZE and OITOOLS.jl show a complex surface with small bright features that appear to vary on a timescale of less than one year and larger features that persist for more than one year. 1D power spectra of these images suggest a characteristic size of $0.52-0.69~R_{\star}$ for the larger, long lived features. This is close to the values of $0.51-0.53~R_{\star}$ derived from 3D RHD models of stellar surfaces. We conclude that interferometric imaging of this star is in line with predictions of 3D RHD models but that short-term imaging is needed to more stringently test predictions of convection in RSGs.

description: Free-text clinical notes detail all aspects of patient care and have great potential to facilitate quality improvement and assurance initiatives as well as advance clinical research. However, concerns about patient privacy and confidentiality limit the use of clinical notes for research. As a result, the information documented in these notes remains unavailable for most researchers. De-identification (de-id), i.e., locating and removing personally identifying protected health information (PHI), is one way of improving access to clinical narratives. However, there are limited off-the-shelf de-identification systems able to consistently detect PHI across different data sources and medical specialties. In this abstract, we present the performance of a state-of-the art de-id system called NeuroNER1 on a diverse set of notes from University of Washington (UW) when the models are trained on data from an external institution (Partners Healthcare) vs. from the same institution (UW). We present results at the level of PHI and note types.

description: Stellar RV jitter due to surface activity may bias the RV semi-amplitude and mass of rocky planets. The amplitude of the jitter may be estimated from the uncertainty in the rotation period, allowing the mass to be more accurately obtained. We find candidate rotation periods for 17 out of 35 TESS Objects of Interest (TOI) hosting <3 R_Earth planets as part of the Magellan-TESS Survey, which is the first-ever statistically robust study of exoplanet masses and radii across the photo-evaporation gap. Seven periods are 3+ sigma detections, two are 1.5+ sigma, and 8 show plausible variability but the periods remain unconfirmed. The other 18 TOIs are non-detections. Candidate rotators include the host stars of the confirmed planets L 168-9 b, the HD 21749 system, LTT 1445 A b, TOI 1062 b, and the L 98-59 system. 13 candidates have no counterpart in the 1000 TOI rotation catalog of Canto Martins et al. (2020). We find periods for G3-M3 dwarfs using combined light curves from TESS and the Evryscope all-sky array of small telescopes, sometimes with longer periods than would be possible with TESS alone. Secure periods range from 1.4 to 26 d with Evryscope-measured photometric amplitudes as small as 2.1 mmag in g'. We also apply Monte Carlo sampling and a Gaussian Process stellar activity model from the code exoplanet to the TESS light curves of 6 TOIs to confirm the Evryscope periods.

Measurement of the top quark mass in the lepton+jets channel using the Ideogram Method

description: A measurement of the top quark mass using events with one charged lepton, missing transverse energy, and jets in the final state, collected by the D0 detector from p-pbar collisions at sqrt{s} = 1.96 TeV at the Fermilab Tevatron collider, is presented. A constrained fit is used to fully reconstruct the kinematics of the events. For every event a top quark mass likelihood is calculated taking into account all possible jet assignments and the probability that an event is signal or background. Lifetime-based identification of b jets is employed to enhance the separation between t-tbar signal and background from other physics processes and to improve the assignment of the observed jets to the quarks in the t-tbar hypothesis. We extract a multiplicative jet energy scale factor JES in-situ, greatly reducing the systematic effect related to the jet energy measurement. In a data sample with an integrated luminosity of 425 pb-1, we observe 230 candidate events, with an estimated background of 123 events, and measure m_t = 173.7 +-4.4 (stat + JES) +2.1/-2.0 (syst) GeV. This result represents the first application of the Ideogram technique to the measurement of the top quark mass in lepton+jets events.

Periodic Orbit can be Evolutionarily Stable: Case Study of Discrete Replicator Dynamics

description: In evolutionary game theory, it is customary to be partial to the dynamical models possessing fixed points so that they may be understood as the attainment of evolutionary stability, and hence, Nash equilibrium. Any show of periodic or chaotic solution is many a time perceived as a shortcoming of the corresponding game dynamic because (Nash) equilibrium play is supposed to be robust and persistent behaviour, and any other behaviour in nature is deemed transient. Consequently, there is a lack of attempt to connect the non-fixed point solutions with the game theoretic concepts. Here we provide a way to render game theoretic meaning to periodic solutions. To this end, we consider a replicator map that models Darwinian selection mechanism in unstructured infinite-sized population whose individuals reproduce asexually forming non-overlapping generations. This is one of the simplest evolutionary game dynamic that exhibits periodic solutions giving way to chaotic solutions (as parameters related to reproductive fitness change) and also obeys the folk theorems connecting fixed point solutions with Nash equilibrium. Interestingly, we find that a modified Darwinian fitness -- termed heterogeneity payoff -- in the corresponding population game must be put forward as (conventional) fitness times the probability that two arbitrarily chosen individuals of the population adopt two different strategies. The evolutionary dynamics proceeds as if the individuals optimize the heterogeneity payoff to reach an evolutionarily stable orbit, should it exist. We rigorously prove that a locally asymptotically stable period orbit must be heterogeneity stable orbit -- a generalization of evolutionarily stable state.

description: We investigate the impact of magnetic fields on the electron distribution in the electrosphere of quark stars. For moderately strong magnetic fields $B\sim 10^{13}$G, quantization effects are generally weak due to the large number density of electrons at surface, but can nevertheless affect the spectral features of quark stars. We outline the main observational characteristics of quark stars as determined by their surface emission, and briefly discuss their formation in explosive events termed Quark-Novae, which may be connected to the $r$-process.

description: The shear viscosity to entropy ratio ($η/s$) is estimated for the hot and dense QCD matter created in Au+Au collisions at RHIC ($\sqrt{s_{NN}}=200$ GeV). A very low value is found $η/s \sim 0.1$, which is close to the conjectured lower bound ($1/4π$). It is argued that such a low value is indicative of thermodynamic trajectories for the decaying matter which lie close to the QCD critical end point.

description: Αντικείμενο της παρούσας διπλωματικής εργασίας αποτελεί η διεξοδική εξέταση ιατρικών, νομικών και ηθικών ζητημάτων τριών ειδικών μορφών ιατρικά υποβοηθούμενης αναπαραγωγής και συγκεκριμένα της παρένθετης μητρότητας, της μεταθανάτιας γονιμοποίησης και της κλωνοποίησης, μέσα από μία συγκριτική μελέτη του ελληνικού και του γερμανικού δικαίου. Ειδικότερα, αναλύεται η νομοθεσία των δύο χωρών αναφορικά με αυτές τις ειδικές μορφές υποβοηθούμενης αναπαραγωγής, ενώ επισημαίνονται οι αδυναμίες αλλά και τα προβλήματα από την εφαρμογή τους στην πράξη. Τέλος, ιδιαίτερη έμφαση, πέρα από την ανάλυση των δικαιϊκών κανόνων δίνεται στα περιθώρια βελτίωσης των οικείων νομοθεσιών Ελλάδας και Γερμανίας, αλλά και στην προοπτική της εναρμόνισης των νομοθεσιών της υποβοηθούμενης αναπαραγωγής σε επίπεδο ΕΕ ή έστω στην θέσπιση κοινά αποδεκτών κανόνων που θα διασφαλίζουν ένα ελάχιστο επίπεδο προστασίας, με στόχο πάντοτε την ισότιμη μεταχείριση όλων των πολιτών και την απρόσκοπτη πρόσβαση τους στα σημερινά επιτεύγματα της βιοτεχνολογίας για την απόκτηση απογόνων.
description: The purpose of this master thesis is a thorough examination of medical, legal and ethical issues regarding three special forms of medically assisted reproduction and specifically surrogacy, post mortem fertilisation and cloning, through a comparative study of greek and german law. After an analysis of the legislation of the two countries as far as these special forms of assisted reproduction are concerned, weaknesses and problems of their application in practice, are identified. Finally, special emphasis, apart from the analysis of these legal systems, is given to the improvement of the relevant greek and german laws, but also to the prospect of harmonisation of legislations of assisted reproduction at EU level or at least the establishment of commonly accepted standards that ensure a minimum level of protection, aiming at the equal treatment of all citizens and their unhindered access to current achievements of biotechnology in order to obtain offspring.

description: When exoplanets pass in front of their stars, they imprint a transit signature on the stellar light curve which to date has been assumed to be symmetric in time, owing to the planet being modelled as a circular area occulting the stellar surface. However, this signature might be asymmetric due to different temperature/pressure and/or chemical compositions in the different terminator regions of the transiting planet. catwoman is a Python package that allows to model these asymmetric transit lightcurves, calculating lightcurves for any radially symmetric stellar limb darkening law, and where planets are modelled as two semi-circles, of different radii, using the integration algorithm developed in arXiv:1507.08285 and implemented in the batman library, from which catwoman builds upon.

description: Natural Language Processing (NLP) models' current trend consists of using increasingly more extra-data to build the best models as possible. It implies more expensive computational costs and training time, difficulties for deployment, and worries about these models' carbon footprint reveal a critical problem in the future. Against this trend, our goal is to develop NLP models requiring no extra-data and minimizing training time. To do so, in this paper, we explore Markov chain models, Hidden Markov Chain (HMC) and Pairwise Markov Chain (PMC), for NLP segmentation tasks. We apply these models for three classic applications: POS Tagging, Named-Entity-Recognition, and Chunking. We develop an original method to adapt these models for text segmentation's specific challenges to obtain relevant performances with very short training and execution times. PMC achieves equivalent results to those obtained by Conditional Random Fields (CRF), one of the most applied models for these tasks when no extra-data are used. Moreover, PMC has training times 30 times shorter than the CRF ones, which validates this model given our objectives.
