description: We study the emergence of magnetic flux at very small spatial scales (less than 2 arcsec) in the quiet Sun internetwork. To this aim, a time series of spectropolarimetric maps was taken at disk center using the instrument SP/SOT on board Hinode. The LTE inversion of the full Stokes vector measured in the Fe I 6301 and 6302 A lines allows us to retrieve the magnetic flux and topology in the region of study. In the example presented here, the magnetic flux emerges within a granular structure. The horizontal magnetic field appears prior to any significant amount of vertical field. As time goes on, the traces of the horizontal field disappear while the the vertical dipoles drift -carried by the plasma motions- towards the surrounding intergranular lanes. These events take place within typical granulation timescales.

description: The random substitutional solid solution between the antiferromagnetic (AFM) full-Heusler alloy Ru$_2$MnSn and the ferromagnetic (FM) full-Heusler alloy Ru$_2$FeSn provides a rare opportunity to study FM-AFM phase competition in a near-lattice-matched, cubic system, with full solubility. At intermediate $x$ in Ru$_2$Mn$_{1-x}$Fe$_x$Sn this system displays suppressed magnetic ordering temperatures, spatially coexisting FM and AFM order, and strong coercivity enhancement, despite rigorous chemical homogeneity. Here, we construct the most detailed temperature- and $x$-dependent understanding of the magnetic phase competition and coexistence in this system to date, combining wide-temperature-range neutron diffraction and small-angle neutron scattering with magnetometry and specific heat measurements on thoroughly characterized polycrystals. A complete magnetic phase diagram is generated, showing FM-AFM coexistence between $x \approx 0.30$ and $x \approx 0.70$. Important new insight is gained from the extracted length scales for magnetic phase coexistence (25-100 nm), the relative magnetic volume fractions and ordering temperatures, in addition to remarkable $x$-dependent trends in magnetic and electronic contributions to specific heat. An unusual feature in the magnetic phase diagram (an intermediate FM phase) is also shown to arise from an extrinsic effect related to a minor Ru-rich secondary phase. The established magnetic phase diagram is then discussed with the aid of phenomenological modeling, clarifying the nature of the mesoscale phase coexistence with respect to the understanding of disordered Heisenberg models.

description: The entropy principle shows that, for self-gravitating perfect fluid, the Einstein field equations can be derived from the extrema of the total entropy, and the thermodynamical stability criterion are equivalent to the dynamical stability criterion. In this paper, we recast the dynamical criterion for the charged self-gravitating perfect fluid in Einstein-Maxwell theory, and further give the criterion of the star with barotropic condition. In order to obtain the thermodynamical stability criterion, first we get the general formula of the second variation of the total entropy for charged perfect fluid case, and then obtain the thermodynamical criterion for radial perturbation. We show that these two stability criterion are the same, which suggest that the inherent connection between gravity and thermodynamic even when the electric field is taken into account.

title: Greenhouse gas emission from small bog pools in a boreal peatland in Newfoundland, Canada
Creators: name: Akpoguma, Blessing Ivie
Publisher: name: Memorial University of Newofundland
Year: 2019

description: Studies on the greenhouse gases (GHG) potential and emissions from peatlands have been
studied extensively in recent years due to the increasing atmospheric concentration of GHG
and impact on climate change. However, most research estimating GHG emissions and
factors regulating these emissions from peatlands are focused on the terrestrial microforms
of peatlands. Thus, less is known about the GHG emission potential from peatland pools,
which are the aquatic components. I conducted a study in small bog pools during the 2018
growing season to determine the drivers and concentration of CH4 dissolved in pool surface
waters using the headspace method. Also, a five-year growing season (2013, 2014, 2015,
2016 and 2018) static floating chamber was used to quantify the variation in GHG flux
from pools across the growing seasons. Results showed that pools are supersaturated with
CH4 ranging in concentration from 2.32 to 180.98 µmol L-1, among the highest concentration reported for small inland waters. The super-saturation observed in these pools may have been influenced by several biological, chemical, and physical factors but were best predicted by a relationship with temperature, vegetation, dissolved organic carbon (DOC), and pool surface area. I also found that CO2 flux was significantly different across the years (p < 0.05) in which pools acted as sources during 2013 and 2018 ( 𝑥 = 23.91 and 7.79 mmol m-2d-1 respectively) and as sinks in 2014, 2015 and 2016 ( 𝑥 = -7.41, -8.98 and -9.04 mmol m-2 d-1 respectively). In contrast, pools acted mostly as sources of CH4 to the atmosphere in 2013, 2016 and 2018 and were
 egligible sinks during 2014 and 2015 ( 𝑥 = 0.41, 0.00, -0.01, 0.19 and 0.52 mmol m-2 d-1 for years 2013 to 2018 respectively). However, flux of CH4 was not significantly different across the years (P >0.05). Pools acted mostly as negligible sinks of N2O flux, which is typical of ombrotrophic
peatlands. N2O flux did not vary among years (p > 0.05). Pool depth was found to be the
best predictor of CO2 fluxes, while dissolved organic carbon was found to be the major
predictor of CH4 emission. This study shows that the concentration and emission of GHG
from bog pools varies depending on climatic conditions and within pool biogeochemistry,
therefore bog pools’ GHG emission potential can be influenced in future climate scenarios.

description: Pollution of white dwarf atmospheres may be caused by asteroids that originate from the locations of secular and mean-motion resonances in planetary systems. Asteroids in these locations experience increased eccentricity, leading to tidal disruption by the white dwarf. We examine how the $ν_6$ secular resonance shifts outwards into a previously stable region of the asteroid belt, as the star evolves to a white dwarf. Analytic secular models require a planet to be engulfed in order to shift the resonance. We show with numerical simulations that as a planet gets engulfed by the evolving star, the secular resonance shifts and the rate of tidal disruption events increases with the engulfed planet's mass and its orbital separation. We also investigate the behaviour of mean-motion resonances. The width of a mean-motion resonance increases as the star loses mass and becomes a white dwarf. The $ν_6$ secular resonance is more efficient at driving tidal disruptions than mean-motion resonances with Jupiter. By examining 230 observed exoplanetary systems whose central star will evolve into a white dwarf, we find that along with an Earth mass planet at $1\,\rm au$, hot Jupiters at a semi--major axis $a\gtrsim 0.05\,\rm au$ and super--Earths of mass $10\,\rm M_\oplus$ at $a\gtrsim 0.3\,\rm au$ represent planet types whose engulfment shifts resonances enough to cause pollution of the white dwarfs to a degree in agreement with observations.

description: The goal of the Ariel space mission is to observe a large and diversified population of transiting planets around a range of host star types to collect information on their atmospheric composition. The planetary bulk and atmospheric compositions bear the marks of the way the planets formed: Ariel's observations will therefore provide an unprecedented wealth of data to advance our understanding of planet formation in our Galaxy. A number of environmental and evolutionary factors, however, can affect the final atmospheric composition. Here we provide a concise overview of which factors and effects of the star and planet formation processes can shape the atmospheric compositions that will be observed by Ariel, and highlight how Ariel's characteristics make this mission optimally suited to address this very complex problem.

description: The statistical characterization of the distribution of visible matter in the universe is a central problem in modern cosmology. In this respect, a crucial question still lacking a definitive answer concerns how large are the greatest structures in the universe. This point is closely related to whether or not such a distribution can be approximated as being homogeneous on large enough scales. Here we assess this problem by considering the size distribution of superclusters of galaxies and by leveraging on the properties of Zipf-Mandelbrot law, providing a novel approach which complements standard analysis based on the correlation functions. We find that galaxy superclusters are well described by a pure Zipf's law with no deviations and this implies that all the catalogs currently available are not sufficiently large to spot a truncation in the power-law behavior. This finding provides evidence that structures larger than the greatest superclusters already observed are expected to be found when deeper redshift surveys will be completed. As a consequence the scale beyond which galaxy distribution crossovers toward homogeneity, if any, should increase accordingly

Discovery of an Isolated Compact Object at High Galactic Latitude

description: We report discovery of a compact object at high Galactic latitude. The object was initially identified as a ROSAT All-Sky Survey Bright Source Catalog X-ray source, 1RXS J141256.0+792204, statistically likely to possess a high X-ray to optical flux ratio. Further observations using {\em Swift}, Gemini-North, and the Chandra X-ray Observatory refined the source position and confirmed the absence of any optical counterpart to an X-ray to optical flux ratio of F_X/F_V > 8700 (3 sigma). Interpretation of 1RXS J141256.0+792204 -- which we have dubbed Calvera -- as a typical X-ray-dim isolated neutron star would place it at z ~ 5.1 kpc above the Galactic disk -- in the Galactic halo -- implying that it either has an extreme space velocity (v_z >~ 5100 km s-1) or has failed to cool according to theoretical predictions. Interpretations as a persistent anomalous X-ray pulsar, or a ``compact central object'' present conflicts with these classes' typical properties. We conclude the properties of Calvera are most consistent with those of a nearby (80 to 260 pc) radio pulsar, similar to the radio millisecond pulsars of 47 Tuc, with further observations required to confirm this classification. If it is a millisecond pulsar, it has an X-ray flux equal to the X-ray brightest millisecond pulsar (and so is tied for highest flux); is the closest northern hemisphere millisecond pulsar; and is potentially the closest known millisecond pulsar in the sky, making it an interesting target for X-ray-study, a radio pulsar timing array, and LIGO.

Opportunistic Collaborative Beamforming with One-Bit Feedback

description: An energy-efficient opportunistic collaborative beamformer with one-bit feedback is proposed for ad hoc sensor networks over Rayleigh fading channels. In contrast to conventional collaborative beamforming schemes in which each source node uses channel state information to correct its local carrier offset and channel phase, the proposed beamforming scheme opportunistically selects a subset of source nodes whose received signals combine in a quasi-coherent manner at the intended receiver. No local phase-precompensation is performed by the nodes in the opportunistic collaborative beamformer. As a result, each node requires only one-bit of feedback from the destination in order to determine if it should or shouldn't participate in the collaborative beamformer. Theoretical analysis shows that the received signal power obtained with the proposed beamforming scheme scales linearly with the number of available source nodes. Since the the optimal node selection rule requires an exhaustive search over all possible subsets of source nodes, two low-complexity selection algorithms are developed. Simulation results confirm the effectiveness of opportunistic collaborative beamforming with the low-complexity selection algorithms.

description: This paper examines the impact of intellectual property rights (IPR) enforcement on multinationals' choice of input suppliers and industry profits in a host economy. The framework consists of suppliers with heterogeneous capabilities who must engage in a relation-specific investment to customize intermediate inputs upon a transfer payment by final producers. 
An outsourcing contract with better technologically-endowed suppliers requires a lower transfer and generates a higher surplus. Stronger IPR enforcement leads firms to self-select into better quality suppliers on average by reducing their outside option. Weak legal institutions instead make it possible for a larger range of suppliers, including the less capable ones, to form partnerships by granting them a larger outside option. A better IPR environment is more likely to harm lagging countries where the technology distribution is characterized by less capable suppliers.

description: A proper coloring of the vertices of a graph is called a \emph{star coloring} if the union of every two color classes induces a star forest. The star chromatic number $χ_s(G)$ is the smallest number of colors required to obtain a star coloring of $G$. In this paper, we study the relationship between the star chromatic number $χ_s(G)$ and the maximum average degree $\mbox{Mad}(G)$ of a graph $G$. We prove that: (1) If $G$ is a graph with $\mbox{Mad}(G) < \frac{26}{11}$, then $χ_s(G)\leq 4$. (2) If $G$ is a graph with $\mbox{Mad}(G) < \frac{18}{7}$ and girth at least 6, then $χ_s(G)\leq 5$. (3) If $G$ is a graph with $\mbox{Mad}(G) < \frac{8}{3}$ and girth at least 6, then $χ_s(G)\leq 6$. These results are obtained by proving that such graphs admit a particular decomposition into a forest and some independent sets.

It will give an overview of the ESO, focussing on the issue of the ways in which breaches of an ESO may be addressed. The argument is advanced that the ESO’s potential is currently untapped and that it has the ability to make the EAW procedure function more efficiently. This is done through a survey of Irish EAW case-law where the ESO could have been engaged. Finally, it will make suggestions for reform.

description: Urban conditions are monitored by a wide variety of sensors that measure several attributes, such as temperature and traffic volume. The correlations of sensors help to analyze and understand the urban conditions accurately. The correlated attribute pattern (CAP) mining discovers correlations among multiple attributes from the sets of sensors spatially close to each other and temporally correlated in their measurements. In this paper, we develop a visualization system for CAP mining and demonstrate analysis of smart city data. Our visualization system supports an intuitive understanding of mining results via sensor locations on maps and temporal changes of their measurements. In our demonstration scenarios, we provide four smart city datasets collected from China and Santander, Spain. We demonstrate that our system helps interactive analysis of smart city data.

description: We have studied the submillimetre (submm) properties of the following classes of near-infrared (NIR)-selected massive galaxies at high redshifts: BzK-selected star-forming galaxies (BzKs); distant red galaxies (DRGs); and extremely red objects (EROs). We used the SCUBA HAlf Degree Extragalactic Survey (SHADES), the largest uniform submm survey to date. Partial overlap of SIRIUS/NIR images and SHADES in SXDF has allowed us to identify 4 submm-bright NIR-selected galaxies, which are detected in the mid-infrared, 24 micron, and the radio, 1.4 GHz. We find that all of our submm-bright NIR-selected galaxies satisfy the BzK selection criteria, except for one galaxy whose B-z and z-K colours are however close to the BzK colour boundary. Two of the submm-bright NIR-selected galaxies satisfy all of the selection criteria we considered, i.e. they belong to the BzK-DRG-ERO overlapping population, or `extremely red' BzKs. Although these extremely red BzKs are rare (0.25 arcmin^{-2}), up to 20 % of this population could be submm galaxies. This fraction is significantly higher than that found for other galaxy populations studied here. Via a stacking analysis, we have detected the 850 micron flux of submm-faint BzKs and EROs in our SCUBA maps. While the contribution of z~2 BzKs to the submm background is about 10--15 % and similar to that from EROs typically at z~1, BzKs have a higher fraction (~30 %) of submm flux in resolved sources compared with EROs and submm sources as a whole. From the SED fitting analysis for both submm-bright and submm-faint BzKs, we found no clear signature that submm-bright BzKs are experiencing a specifically luminous evolutionary phase, compared with submm-faint BzKs. An alternative explanation might be that submm-bright BzKs are more massive than submm-faint ones.

description: The Inter-university Consortium for Political and Social Research (ICPSR) is developing a computational approach to detect informal data use and construct reliable data impact metrics. Formal data citations that use unique identifiers are readily discoverable; however, informal references made to data are challenging to infer and detect as they are described in many ways and tend to occur in article footnotes, tables, figures, or elsewhere where they are not indexed for search. Identifying data citations is an essential step toward characterizing the impact of research data (i.e., who reuses research data and for what purposes). We use features of text including the presence of indicator terms, sections of articles, and frequency of acronyms, to predict the portions of articles that are likely to indicate data use. We then use a natural language processing (NLP) pipeline to extract candidate data references. In production, our model will support the review of publications to ingest into the ICPSR Bibliography of Data-related Literature as part of a broader effort to measure the impact of research data.
Prediction of P-Y curves from finite element analyses
Creators: name: She, Jairus Lai Yan
Publisher: name: University of British Columbia
Year: 2010

description: The prediction of P-Y curves for undrained clay and sand based on the results of finite element analyses is presented in this thesis. A higher-ordered finite element program was used in the analyses. The ability of the program to accurately model the undrained soil condition was verified by comparing predicted load-deflection responses with closed form solutions for the cylindrical cavity expansion problem. Pressuremeter curves were predicted from plane strain axisymmetric finite element analyses. The effect of pressuremeter size on the predicted results was examined. P-Y curves were predicted for plane strain and plane stress conditions. Values for the initial slope and Pun- of the curves were obtained. The curves were normalized for comparison, and simplified methods presented for determining P-Y curves. Finite element predictions for the pressuremeter and laterally loaded pile problems were also compared. Factors were determined from these comparisons to generate P-Y curves from pressuremeter curves.

description: Vacuum force is an interesting low energy test for brane worlds due to its dependence on field's modes and its role in submillimeter gravity experiments. In this work we generalize a previous model example: the scalar field vacuum force between two parallel plates lying in the brane of a Randall-Sundrum scenario extended by $p$ compact dimensions (RSII-$p$). Upon use of Green's function technique, for the massless scalar field, the 4D force is obtained from a zero mode while corrections turn out attractive and depend on the separation between plates as $l^{-(6+p)}$. For the massive scalar field a quasilocalized mode yields the 4D force with attractive corrections behaving like $l^{-(10+p)}$. Corrections are negligible w.r.t. 4D force for $AdS_{(5+p)}$ radius less than $\sim 10^{-6}$m. Although the $p=0$ case is not physically viable due to the different behavior in regard to localization for the massless scalar and electromagnetic fields it yields an useful comparison between the dimensional regularization and Green's function techniques as we describe in the discussion.

description: This Insight analyses the aim of victim protection in the Framework Decision 2009/829/JHA and its limited use-fulness, despite being regarded as one of the main objectives of the recognition and enforcement of judicial deci-sions on supervision measures. After explaining the apparent aims of the Framework Decision, the Insight ad-dresses the victims’ rights in the pre-trial stage according to Directive 2012/29/EU on victims’ rights and Directive 2011/99/EU on the European Protection Order, whose aim is to ensure that victims of crime receive appropriate information, support, and protection. Particular attention is dedicated to the victims’ right to information, which is also instrumental for their right to protection. The analysis shows that victims’ rights do not play a role in the assessment of whether or not to forward the certificate or maintain the supervision measures adopted.

The K-band spectra of WR102ka and WR102c are exploited to infer the stellar parameters and to compute synthetic stellar spectra using the Potsdam Wolf-Rayet (PoWR) model atmosphere code. These models are combined with dust-shell models for analyzing the Spitzer IRS spectra of these objects. Archival IR images complement the interpretation. We report that WR102ka and WR102c are among the most luminous stars in the Milky Way. The mid-IR continua for both objects are dominated by dust emission. For the first time we report the presence of dust in the close vicinity of WN stars. Also for the first time, we have detected lines of pure-rotational transitions of molecular hydrogen in a massive-star nebula. A peony-shaped nebula around 102ka is resolved by the Spitzer MIPS camera. We attribute the formation of this nebula to the recent evolutionary history of WR102ka.

description: Many businesses and industries nowadays rely on large quantities of time series data making time series forecasting an important research area. Global forecasting models that are trained across sets of time series have shown a huge potential in providing accurate forecasts compared with the traditional univariate forecasting models that work on isolated series. However, there are currently no comprehensive time series archives for forecasting that contain datasets of time series from similar sources available for the research community to evaluate the performance of new global forecasting algorithms over a wide variety of datasets. In this paper, we present such a comprehensive time series forecasting archive containing 20 publicly available time series datasets from varied domains, with different characteristics in terms of frequency, series lengths, and inclusion of missing values. We also characterise the datasets, and identify similarities and differences among them, by conducting a feature analysis. Furthermore, we present the performance of a set of standard baseline forecasting methods over all datasets across eight error metrics, for the benefit of researchers using the archive to benchmark their forecasting algorithms.

Subjects: Uncategorized

description: This project aims to provide methodology on a digital product line for an SME by using techniques more commonly seen in larger companies. Through techniques drawn from Software Product Lines, Service-Oriented Architecture and Microservices, I design the implementation for such a system. This is applied to one particular company to prove that the methodology has practical grounding. The practical lessons are then lifted to the general SME level, evaluating key benefits, drawbacks and indicators for readiness in the adoption of a similar system. Finally I look that how research could further be developed, such as with AI-driven re-configuration and wider practical testing.

description: Recent observations suggest the incidence of strong intervening MgII absorption systems along the line-of-sight to gamma ray burst (GRB) afterglows is significantly higher than expected from analogous quasar sightlines. One possible explanation is a geometric effect, arising because MgII absorbers only partially cover the quasar continuum regions, in which case MgII absorbers must be considerably smaller than previous estimates. We investigate the production of abnormal absorption profiles by partial coverage and conclude that the lack of any known anomalous profiles in observed systems, whilst constraining, cannot on its own rule out patchy MgII absorbers. In a separate test, we look for differences in the distribution function of MgII equivalent widths over quasar continuum regions and CIII] emission lines. We show that these anomalies should be observable in any scenario where MgII absorbers are very small, but they are not present in the data. We conclude that models invoking small MgII cloudlets to explain the excess of absorbers seen towards GRBs are ruled out.

description: On account of its application to the present and future analysis of the virtual photon correction to the hadronic properties by means of lattice QCD simulation, we initiate the study of the finite size scaling effect on the QED correction using low energy effective theory of QCD with QED. For this purpose, we begin with formulating a new QED on the space with finite volume. By adapting this formalism to the partially quenched QCD with electromagnetism, we explore the qualitative features of the finite size scaling effect on the electromagnetic correction to the masses of pseudo-Goldstone bosons.

Full scale dynamic testing of the Annacis cable stayed bridge
Creators: name: Vincent, Douglas Hillyard Charles
Publisher: name: University of British Columbia
Year: 2010

description: Cantilever construction techniques and reduced deck bending moments have made cable stayed bridges popular for long spans. Recently; however, large amplitude wind induced cable vibration problems have occurred on several of these long span bridges. One of these bridges had several of its longest cables fitted with discrete dampers near the lower end cable socket. Although effective, these discrete dampers, which resemble large shock absorbers, are obvious and very unappealing. Some of these large cable oscillations are caused by eddy shedding but others appear to be created by some other means of excitation. Past research suggests that wind induced support motion combined with low damping in the cables may produce local vibration problems. Many authors have proposed closed form and analytical solutions to the dynamic response of a cable with sag. Due to a lack of measured values, estimates of cable damping have been used in these analyses. Although seme scale model tests of a cable stayed bridge have been done, no actual full scale tests have been performed. With the Annacis cable stayed bridge being constructed in the Vancouver area a unique opportunity arose to perform full scale dynamic tests of the cables as well as the entire bridge. Through a series of tests of cables of varying length, the natural frequency and damping value of each cable was determined. A parameter study was undertaken in order to determine the nature of the damping present. Each of the cables supporting the Annacis bridge is fitted with a split neo-prene ring in the cable anchorage assembly at each end. Hidden from view, this neoprene ring was designed to seal the top socket and provide a discrete damper at each end of the cable. Tests done before and after these dampers were in place determined their effectiveness. The possibility of large cable motions being caused by wind induced support motion as suggested by the previous literature was investigated. Tests were carried out to determine if cable motions were harmonically related to the motion of the towers or deck. Finally a simple pendulum was used to harmonically excite the completed bridge in several of its lower modes. This test provided a check on the natural frequencies of these modes as well as providing full bridge damping values from the free vibration response.

description: O poema VIII d’O Guardador de Rebanhos é a narrativa de um sonho em que Caeiro recebe a visita do Menino Jesus. À descrição de como fugiu do céu e à enumeração das travessuras a que esta criança se dedica na Terra segue-se a revelação de que Caeiro, o mestre de todos os outros heterónimos e do próprio Pessoa, foi também discípulo. Que o Menino Jesus tenha sido para Caeiro o que este foi para todos os outros é talvez suficiente para que se possa afirmar que aquilo que se narra neste poema está para a vida de Caeiro como aquilo que é dito acerca do dia triunfal na famosa carta a Casais Monteiro está para a vida de Fernando Pessoa. Por estes motivos, procurará este ensaio defender que o poema VIII contém a primeira reflexão suficientemente séria acerca do alegado triunfalismo da obra de Pessoa.

description: We develop the mechanics of combined bending and twisting deformation of a one-dimensional filamentous structure with protruding stiff fish-scale-like plates embedded at an angle on the surface. We develop Cosserat kinematic formulation along with scale contact constraints. This geometrically exact model allows us to bypass the limitations of typical finite element computations inherent in these systems when deflections are large. The derived structure-property relationships reveal for the first time the combined effect of bending and twisting on a slender fish scale inspired substrate. The model subsumes previous models on pure bending and twisting but also shows previously unobserved phenomena that arise due to the coupled effects of these loads. This includes a new interpretation of kinematic locking behavior, multiple contact regimes, asymmetric sensitivities of one curvature over the other, and sharp transitions in the nonlinear moment-curvature and torque-twist behaviors reflecting the complex scale engagement patterns.
Fingerprints of the Very Early Universe

Publisher: name: Università degli Studi di Napoli Federico II

description: During the work developed in the PhD Thesis, it has been faced a number of problems
concerning theoretical cosmology especially with respect dynamical evolution of the Universe
near the cosmological singularity.
Wide space has been devoted to the study of the subtle question concerning the covariance
chaoticity, which led to important issues favourable to the independence of the ‘’chaos’’ with
respect to the choice of the temporal gauge. Such analysis found its basis either on the
standard approach using the Jacobi metric (a scheme allowed by the existence of an energy
like constant of motion), either by a statistical mechanics approach in which the mixmaster
evolution is represented as a billiard on a Lobatchevski plane and therefore admitting a
microcanonical ensemble associated to such energy-like constant.
Furthermore, an important step consisted in searching a Physical link between the chaoticity
characterizing the system at a classical level and the quantum indeterminism appearing in the
Planckian era for such a model. More precisely it was constructed che canonical quantization of
the model via a Schroedinger approach (equivalent to the Wheeler-DeWitt scheme) and then
developed the WKB semiclassical limit to be compared with the classical dynamics. As an
issue, it resulted a correspondence between the continuity equation of the microcanonical
distribution function and that one describing the dynamics of the first order corrections in the
wave function for h  0.
It is remarkable the investigation performed about a quasi-isotropic inflationary solution, which
allowed to confirm how there is non chance for classical inhomogeneous perturbations to
survive after the DeSitter phase; such an analysis supports strongly the idea that only quantum
fluctuations ofthe scalar field can provide a satisfactory esplanation for the observed spectrum
of inhomogeneous perturbations.
A detailed discussion was pursued in view of clarifying the peculiarity existing to characterize
chaos in General Relativity; in particular, it has been provived a critical discussion on the
predictivity allowed by the fractal basin boundary approach in qualifying the nature of the
mixmaster dynamics; the main issue on this direction relies on the numerical approximations
limits when treating iterations of irrational numbers and overall on the potential methods
commonly adopted in the dynamical systems approach.
With this respect it is emphasized the ambiguity of describing chaos in terms of geodesic
deviation when the backgroun metric is a pseudo Riemannian one; a correct characterization of
the Lyapunov exponents required a projection of the connecting vector toward a Fermi basis.
