description: We show that the secant variety of the Segre variety gives useful information about the geometrical structure of an arbitrary multipartite quantum system. In particular, we investigate the relation between arbitrary bipartite and three-partite entangled states and this secant variety. We also discuss the geometry of an arbitrary general multipartite state.

description: We present fully differential predictions for the production cross section of a Higgs boson via the gluon fusion mechanism at next-to-next-to-next-to leading order (N$^3$LO) in QCD perturbation theory. To perform our calculation we apply the Projection-to-Born method for the first time to the calculation of the non-factorising production of a colorless final state at the LHC at N$^3$LO. We predict differential distributions for the two photon final state produced by the decay of the Higgs boson and apply fiducial cuts on the photon rapidities and momenta. The N$^3$LO corrections to these differential distributions have complex features and are in part larger than the inclusive N$^3$LO corrections to the production cross section. Overall, we observe that the inclusion of the N$^3$LO QCD corrections significantly reduces the perturbative uncertainties and leads to a stabilisation of the perturbative expansion.

description: This thesis is an investigation of the formal and phenomenological characteristics of a specific spatial morphology: narrow, tall, long, habitable space which occurs between at least two other spaces whether connected or not. This investigation does not aim to address all types of interstitial space. The general form of the space is the constant; variables include size, scale, modulation, intended and unintended uses. The method of investigation will be the creation of a matrix of examples that allows sorting by the various categories. It is expected that examining sorted categories will lead to a comprehensive and profound understanding of this spatial type. And that this, in turn, will prompt a program that will provide the basis for a demonstration of the range of uses of this spatial type. An investigation of the interstitial is intended to illuminate the author’s affinity and intuitive use of this spatial form in her work and to generate a framework for the author from which to approach architecture, using interstitial space intentionally as the primary organization and driver of form in future explorations.

description: We investigate in detail a recent model of colliding mobile agents [Phys. Rev. Lett.~96, 088702], used as an alternative approach to construct evolving networks of interactions formed by the collisions governed by suitable dynamical rules. The system of mobile agents evolves towards a quasi-stationary state which is, apart small fluctuations, well characterized by the density of the system and the residence time of the agents. The residence time defines a collision rate and by varying the collision rate, the system percolates at a critical value, with the emergence of a giant cluster whose critical exponents are the ones of two-dimensional percolation. Further, the degree and clustering coefficient distributions and the average path length show that the network associated with such a system presents non-trivial features which, depending on the collision rule, enables one not only to recover the main properties of standard networks, such as exponential, random and scale-free networks, but also to obtain other topological structures. Namely, we show a specific example where the obtained structure has topological features which characterize accurately the structure and evolution of social networks in different contexts, ranging from networks of acquaintances to networks of sexual contacts.

description: Homelessness is a state to recover from, not a problem to fix. Currently in the United States, there are three main strategies provided for aiding the homeless: emergency shelters, permanent housing, and transitional housing. Emergency shelters provide temporary services, however they are often associated with crime, filth, and danger . Permanent housing programs aim to get the homeless of the street and into housing while providing social services, yet places the burden of proof on applicants. Transitional housing however provides temporary living situations and supportive services with an ultimate goal of helping homeless individuals and families prepare to reenter permanent housing, transition to independent living, and become productive members of society.

This thesis focuses on models of transitional and supportive housing, and how through design, the needs of homeless individuals and families are best provided for through services. This thesis explores how locating programs and facilities in the underserved community of Harlem Park Baltimore, MD can integrate two communities that have been isolated and neglected.
Cosmological constraints from the power spectrum of eBOSS emission line galaxies
Creators: name: Ivanov, Mikhail M.
Publisher: name: arXiv

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: We present cosmological parameter measurements from the effective field theory-based full-shape analysis of the power spectrum of emission line galaxies (ELGs). First, we perform extensive tests on simulations and determine appropriate scale cuts for the perturbative description of the ELG power spectrum. We study in detail non-linear redshift-space distortions (``fingers-of-God'') for this sample and show that they are somewhat weaker than those of luminous red galaxies. This difference is not significant for current data, but may become important for future surveys like Euclid/DESI. Then we analyze recent measurements of the ELG power spectrum from the extended Baryon acoustic Oscillation Spectroscopic Survey (eBOSS) within the $νΛ$CDM model. Combined with the BBN baryon density prior, the ELG pre- and post-reconstructed power spectra alone constrain the matter density $Ω_m=0.257_{-0.045}^{+0.031}$, the current mass fluctuation amplitude $σ_8=0.571_{-0.076}^{+0.052}$, and the Hubble constant $H_0=84.5_{-7}^{+5.8}$ km/s/Mpc (all at 68\% CL). Combining with other full-shape and BAO data we measure $Ω_m=0.327_{-0.016}^{+0.014}$, $σ_8=0.69_{-0.045}^{+0.038}$, and $H_0=68.6_{-1.1}^{+1}$ km/s/Mpc. The total neutrino mass is constrained to be $M_{\rm tot}<0.63$ eV (95\% CL) from the BBN, full-shape and BAO data only. Finally, we discuss the apparent $\sim 3σ$ discrepancy in the inferred clustering amplitude between our full shape analysis and the cosmic microwave background data.

Θα λέγαμε μάλιστα ότι η συνεκπαίδευση αποτελεί σήμερα την κυρίαρχη άποψη στον εκπαιδευτικό χώρο. Ωστόσο, τα προβλήματα για την εκπαίδευση χωρίς αποκλεισμούς είναι πολλά. Ένα από αυτά είναι οι στάσεις των εκπαιδευτικών απέναντι στη νέα αυτή εκπαιδευτική πρακτική. Όπως επισημαίνουν πολλοί συγγραφείς, οι εκπαιδευτικοί διαδραματίζουν σημαντικό ρόλο στην εφαρμογή ενός σχολείου για όλους. Οι στάσεις και οι απόψεις των άμεσα εμπλεκομένων, δηλαδή των εκπαιδευτικών, κίνησε το ενδιαφέρον του ερευνητή για μεγαλύτερη διερεύνηση. Στην έρευνα συμμετείχαν 80 εκπαιδευτικοί (40 γενικής και 40 ειδικής αγωγής). Όπως διαπιστώθηκε από τα αποτελέματα της έρευνας, οι εκπαιδευτικοί μπορεί να θεωρούν μεν θετική την ιδέα της ένταξης, διατηρούν όμως σημαντικές επιφυλάξεις για το είδος της αναπηρίας. Επιπλέον θεωρούν ως καταλληλότερο χώρο εκπαίδευσης για τους μαθητές με νοητική ανεπάρκεια τις δομές της ειδικής αγωγής
description: In recent years, there has been a great deal of interest in educating children with special needs and integrating them into mainstream schools. We will even say that co-education is the predominant view of education today. However, many are the problems for the implementation of non-inclusive education. One of these is the attitudes of teachers towards this new educational practice. As many writers have pointed out, educators play an important role in implementing a school for all. The attitudes and beliefs of the directly involved, i.e teachers, have raised the interest of the researcher for further research . 80 teachers participated in the survey (40 general and 40 special education). It is clear from the results of the research that teachers may have positive attitude towards integration , but they have important reservations about the type of disability. In addition, they consider the special education structures to be the most appropriate place for students with mental deficiency

description: Evidential occupancy grid maps (OGMs) are a popular representation of the environment of automated vehicles. Inverse sensor models (ISMs) are used to compute OGMs from sensor data such as lidar point clouds. Geometric ISMs show a limited performance when estimating states in unobserved but inferable areas and have difficulties dealing with ambiguous input. Deep learning-based ISMs face the challenge of limited training data and they often cannot handle uncertainty quantification yet. We propose a deep learning-based framework for learning an OGM algorithm which is both capable of quantifying first- and second-order uncertainty and which does not rely on manually labeled data. Results on synthetic and on real-world data show superiority over other approaches. Source code and datasets are available at https://github.com/ika-rwth-aachen/EviLOG

description: This is the second paper of a series devoted to study the stellar content of early-type galaxies. The goal of the series is to set constraints on the evolutionary status of these objects. We use a new set of models which include an improved stellar library (MILES) to derive simple stellar population (SSP)-equivalent parameters in a sample of 98 early-type galaxies. The sample contains galaxies in the field, poor groups, and galaxies in the Virgo and Coma clusters.We find that low-density environment galaxies span a larger range in SSP age and metallicity than their counterparts in high density environments, with a tendency for lower sigma galaxies to be younger. Early-type galaxies in low-density environments appear on average ~1.5 Gyr younger and more metal rich than their counterparts in high density environments. The sample of low-density environment galaxies shows an age metallicity relation in which younger galaxies are found to be more metal rich, but only when metallicity is measured with a Fe-sensitive index. Conversely, there is no age-metallicity relation when the metallicity is measured with a Mg sensitive index. The mass-metallicity relation is only appreciable for the low-density environment galaxies when the metallicity is measured with a Mg-sensitive index and not when the metallicity is measured with other indicators. On the contrary, this relation exists for the high-density environment galaxies independently of the indicator used to measure the metallicity. This suggests a dependence of the mass-metallicity relation on the environment of the galaxies. Our data favour a scenario in which galaxies in low density environments have suffered a more extended star formation history than the galaxies in the Coma cluster, which appear to host more homogenous stellar populations.

Multiparameter universality and conformal field theory for anisotropic confined systems: test by Monte Carlo simulations

description: Analytic predictions have been derived recently by V. Dohm and S. Wessel, Phys. Rev. Lett. {\bf 126}, 060601 (2021) from anisotropic $φ^4$ theory and conformal field theory for the amplitude ${\cal F}_c$ of the critical free energy of finite anisotropic systems in the two-dimensional Ising universality class. These predictions employ the hypothesis of multiparameter universality. We test these predictions by means of high-precision Monte Carlo (MC) simulations for ${\cal F}_c$ of the Ising model on a square lattice with isotropic ferromagnetic couplings between nearest neighbors and with an anisotropic coupling between next-nearest neighbors along one diagonal. We find remarkable agreement between the MC data and the analytical prediction. This agreement supports the validity of multiparameter universality and invalidates two-scale-factor universality as ${\cal F}_c$ is found to exhibit a nonuniversal dependence on the microscopic couplings of the scalar $φ^4$ model and the Ising model. Our results are compared with the exact result for ${\cal F}_c$ in the three-dimensional $φ^4$ model with a planar anisotropy in the spherical limit. The critical Casimir amplitude is briefly discussed.
Search for Standard Model Higgs Boson Production in Association with a W Boson at CDF

description: We present a search for standard model Higgs boson production in association with a W boson in proton-antiproton collisions ($p\bar{p}\to W^\pm H \to \ellνb\bar{b}$) at a center of mass energy of 1.96 TeV. The search employs data collected with the CDF II detector which correspond to an integrated luminosity of approximately 1 fb-1. We select events consistent with a signature of a single lepton ($e^\pm/μ^\pm$), missing transverse energy, and two jets. Jets corresponding to bottom quarks are identified with a secondary vertex tagging method and a neural network filter technique. The observed number of events and the dijet mass distributions are consistent with the standard model background expectations, and we set 95% confidence level upper limits on the production cross section times branching ratio ranging from 3.9 to 1.3 pb for Higgs boson masses from 110 to 150 GeV/c2, respectively.

description: The world has begun to recognize that potable, or drinkable, water is a limited commodity that therefore needs to be used conservatively.  Growing populations and changing climates are intensifying the need to conserve.  At the present, homes built in the United States do not use water or energy efficiently.  Reasons for these inefficiencies include abundant cheap energy and water as well as a home building culture that does not design to the natural conditions in local environments.  When building culture accepts that the methods and aesthetic of structures must vary based on geography, significant environmental savings can occur.  The goal of this project is to establish a variety of water conservative, net-zero energy single-family homes that can be used as prototypes for new development in arid climates throughout the Western United States.

description: A continuous variable ping-pong scheme, which is utilized to generate deterministically private key, is proposed. The proposed scheme is implemented physically by using Gaussian-modulated squeezed states. The deterministic way, i.e., no basis reconciliation between two parties, leads a two-times efficiency comparing to the standard quantum key distribution schemes. Especially, the separate control mode does not need in the proposed scheme so that it is simpler and more available than previous ping-pong schemes. The attacker may be detected easily through the fidelity of the transmitted signal, and may not be successful in the beam splitter attack strategy.

description: Here, we introduce and apply non-Abelian tensor Berry connections to topological phases in multi-band systems. These gauge connections behave as non-Abelian antisymmetric tensor gauge fields in momentum space and naturally generalize Abelian tensor Berry connections and ordinary non-Abelian (vector) Berry connections. We build these novel gauge fields from momentum-space Higgs fields, which emerge from the degenerate band structure of degenerate-band models. Firstly, we show that the conventional topological invariants of two-dimensional topological insulators and three-dimensional Dirac semimetals can be derived from the winding number associated to the Higgs field. Secondly, through the non-Abelian tensor Berry connections we construct higher-dimensional Berry-Zak phases and show their role in the topological characterization of several gapped and gapless systems, ranging from two-dimensional Euler insulators to four-dimensional Dirac semimetals. Importantly, through our new theoretical formalism, we identify and characterize a novel class of models that support space-time inversion and chiral symmetries. Our work provides an unifying framework for different multi-band topological systems and sheds new light on the emergence of non-Abelian gauge fields in condensed matter physics, with direct implications on the search for novel topological phases in solid-state and synthetic systems.

description: The Lorentz transformation is entirely derived from length contraction, itself established through the known light-clock thought experiment . This makes the derivation accessible to beginning students once Eintein's two postulates have been admitted. The formula derived for the space part of the general rotation-free Lorentz transformation is very compact and allows for an easy derivation of the velocity and acceleration transformations. A possibly new and very simple relation is found between proper acceleration and acceleration in an inertial frame.

description: While quantum measurement theories are built around density matrices and observables, the laws of thermodynamics are based on processes such as are used in heat engines and refrigerators. The study of quantum thermodynamics fuses these two distinct paradigms. In this article, we highlight the usage of quantum process matrices as a unified language for describing thermodynamic processes in the quantum regime. We experimentally demonstrate this in the context of a quantum Maxwell's demon, where two major quantities are commonly investigated; the average work extraction $\langle W \rangle$ and the efficacy $γ$ which measures how efficiently the feedback operation uses the obtained information. Using the tool of quantum process matrices, we develop the optimal feedback protocols for these two quantities and experimentally investigate them in a superconducting circuit QED setup.

description: As a result of rapid development in the last 40 years, modern Korean housing has experienced the indiscriminate vertical growth of high-rise slab construction which has overlooked both the traditions of the Korean family and society that were embodied in the traditional house. This has compromised cultural and generational relationships, created conflicts among neighbors, and isolated people from nature thereby causing disconnection between Koreans and their own unique cultural elements. Contrary to the current housing conditions, Korean desire for a healthier environment and cultural standing in the world keeps rising. This thesis will introduce design strategies and concepts to help mitigate these problems in contemporary housing by proposing a new type of housing in Seoul, Korea that supports the tradition and characteristic of Korea. It will identify the essence of tradition embodied in the traditional house, and re-envision contemporary design ideas for Korean society that can lead to new types of and more enlightened housing for its future.

description: Discrete time crystals (DTCs) refer to a novel many-body steady state that spontaneously breaks the discrete time-translational symmetry in a periodically-driven quantum system. Here, we study DTCs in a Bose-Einstein condensate (BEC) bouncing resonantly on an oscillating mirror, using a two-mode model derived from a standard quantum field theory. We investigate the validity of this model and apply it to study the long-time behavior of our system. A wide variety of initial states based on two Wannier modes are considered. We find that in previous studies the investigated phenomena in the evolution time-window ($\lessapprox$2000 driving periods) are actually "short-time" transient behavior though DTC formation signaled by the sub-harmonic responses is still shown if the inter-boson interaction is strong enough. After a much longer (about 20 times) evolution time, initial states with no "long-range" correlations relax to a steady state, where time-symmetry breaking can be unambiguously defined. Quantum revivals also eventually occur. This long-time behavior can be understood via the many-body Floquet quasi-eigenenergy spectrum of the two-mode model. A symmetry-breaking edge for DTC formation appears in the spectrum for strong enough interaction, where all quasi-eigenstates below the edge are symmetry-breaking while those above the edge are symmetric. The late-time steady state's time-translational symmetry depends solely on whether the initial energy is above or below the symmetry-breaking edge. A phase diagram showing regions of symmetry-broken and symmetric phases for differing initial energies and interaction strengths is presented. We find that according to this two-mode model, the discrete time crystal survives for times out to at least 250,000 driving periods.

description: Vibrationally excited emission from the SiO and H2O molecules probes the innermost circumstellar envelopes of oxygen-rich red giant and supergiant stars. VY CMa is the most prolific known stellar emission source in these molecules. Observations were made to search for rotational lines in the lowest vibrationally excited state of H2O. The APEX telescope was used for observations of H2O lines at frequencies around 300 GHz. Two vibrationally excited H2O lines were detected, a third one could not be found. In one of the lines we find evidence for weak maser action, similar to known (sub)millimeter H2O lines. We find that the other line's intensity is consistent with thermal excitation by the circumstellar infrared radiation field. Several SiO lines were detected together with the H2O lines.

description: This thesis explores the proposition that the under-utilized centers of smaller U.S. cities that were once vital but are now struggling due to a loss of industry, jobs, population decentralization and shifts in transit leading to the collapse of their social and business infrastructure, can be revitalized by evidencing, displaying, merchandizing and rebranding their past to become tourist destinations. Adjustments to the urban fabric, at the scale of the city and individual buildings, can awaken ideals of the past that can invigorate decaying city centers. Hagerstown Maryland is selected as a demonstration of this proposition.

description: Πλήθος ερευνών έχουν τονίσει τη σημαντική εμπλοκή των γνωστικών διεργασιών στη γλωσσική ανάπτυξη και κυρίως έχουν επικεντρωθεί στην μορφοσυντακτική κατανόηση. Αντίθετα, η σχέση μεταξύ των γνωστικών διεργασιών και της μορφοσυντακτικής παραγωγής έχει μελετηθεί ελάχιστα. Σκοπός της παρούσας έρευνας είναι η εκτίμηση των γνωστικών διεργασιών στον τρόπο που ανακαλούμε και παράγουμε τον γραμματικά ορθό ρηματικό τύπο μέσα σε μία πρόταση. Ειδικότερα, εξετάζεται ο ρόλος της εργαζόμενης μνήμης, του ανασταλτικού ελέγχου, της ταχύτητας επεξεργασίας πληροφοριών και του μορφωτικού επιπέδου, στη μορφοσυντακτική παραγωγή σε επίπεδο πρότασης. Εστιάσαμε σε τρεις μορφοσυντακτικές κατηγορίες που συνδέονται με το ρήμα: τη συμφωνία υποκειμένου-ρήματος, τον χρόνο του ρήματος και την όψη του. Στην έρευνα συμμετείχαν ογδόντα Έλληνες υγιείς ενήλικες. Συνοπτικά τα αποτελέσματα της έρευνας έδειξαν ότι η εκπαίδευση ως ατομικός παράγοντας επηρεάζει σημαντικά την μορφοσυντακτική παραγωγή. Επίσης, και οι γνωστικές διεργασίες επιδρούν στην παραγωγή μιας πρότασης
description: The majority of studies emphasized the important involvement of cognitive processes in language processing. Mainly have focused on language comprehension. In contrast, the relationship between cognitive processes and morphosyntactic production has investigated barely. Purpose of the present work is to investigate the role of working memory, inhibition, processing speed and education in sentence production. We focused on three morphosyntactic categories of verb: subject – verb agreement, tense and aspect. Eighty Greek healthy adults participated in this study. Concisely, results showed that education as individual factor, affect significantly on sentence production. Also cognitive processes affect on morphosyntactic production.

description: This thesis is an investigation of how buildings can be designed to encourage pro-environmental behavior by engaging users in a sustainable built environment. By engaging users in sustainability building design can reestablish a cultural understanding of humanity’s interdependence with the natural environment. The basis for investigation is a brief analysis of how cultural perceptions of the natural environment have changed over time and an understanding of what motivates pro-environmental behavior. Understanding of the types of work done and spaces used by building occupants throughout a work day informs opportunities for user engagement in the production, consumption, recycling and monitoring of energy, water and waste. Insights revealed through this research culminate in a design proposal for an office building that integrates user engagement with sustainable building performance and puts us on a path toward cultural transition to sustainable behavior and symbiosis with the natural environment.

description: Recently the drift-reduced Landau fluid six-field turbulence model within the BOUT++ framework has been upgraded. In particular, this new model employs a new normalization, adds a volumetric flux-driven source option, the Landau fluid closure for parallel heat flux and a Laplacian inversion solver which is able to capture n=0 axisymmetric mode evolution in realistic tokamak configurations. These improvements substantially extended model's capability to study a wider range of tokamak edge phenomena, and are essential to build a fully self-consistent edge turbulence model capable of both transient (e.g., ELM, disruption) and transport time-scale simulations.

description: As the world population expands with no reduction in conflict, there has been a rapid increase in the numbers of refugees. With such a massive increase in refugees, it is important to review the built environment that people inhabit within refugee camps. In theory,  refugee camps are built to be a temporary settlement, whether planned or impromptu it is meant to meet basic human needs for a short period of time. But in reality, these temporary settlements end up being populated for long periods of time, mimicking the physical organizations seen in small towns and cities. Such places should no longer be seen as short term transitional population centers but permanent settlements. In this thesis I will explored the long-term planning of refugee camps with a critical look at: how refugee camps evolve over time; the strategies people use to make these spaces their own as the camp evolves; whether camp plans relate to the cultural living patterns of the refugees; how camps might be planned to reduce dependence on the host country; and how the design of the camps might be guided by an understanding of these factors.

This thesis was explored through the lens of the Syrian Civil War and the refugees that it has unfortunately produced. Through the study of  precedent camps, a cluster formation of shelter was observed. The thesis proposes to give refugees a plot of land as well as a shelter that is modifiable over time. The cluster formation of plots is used as module to create community spaces at all different scales.

description: We present a novel baryogenesis mechanism in which the asymmetry is sourced from heavy particles which either gain their mass or are created during bubble expansion in a strong first order phase transition. These particles then decay in a CP and baryon number violating way inside the bubble. The particles are inherently out-of-equilibrium and sufficiently dilute after wall crossing so the third Sakharov condition is easily met. Washout is avoided provided the reheat temperature is sufficiently below the scale of the heavy particles. The mechanism relies on moderate supercooling and relativistic walls which -- in contrast to electroweak baryogenesis -- generically leads to a sizable gravitational wave signal, although in the simplest realisations at frequencies beyond upcoming detectors. We present a simple example model and discuss the restrictions on the parameter space for the mechanism to be successful. We find that high reheat temperatures $T_{\rm RH} \gtrsim 10^{10}$ GeV are generally preferred, whereas stronger supercooling allows for temperatures as low as $T_{\rm RH} \sim 10^{6}$ GeV, provided the vacuum energy density is sufficiently suppressed. We briefly comment on using resonantly enhanced CP violation to achieve even lower scales.

description: We show that current correlations at the exit ports of a beam splitter can be used to detect electronic entanglement for a fairly general input state. This includes the situation where electron pairs can enter the beam splitter from the same port or be separated due to backscattering. The proposed scheme allows to discriminate between occupation-number and degree-of-freedom entanglement.

description: Quantum dots (QDs) defined with electrostatic gates are a leading platform for a scalable quantum computing implementation. However, with increasing numbers of qubits, the complexity of the control parameter space also grows. Traditional measurement techniques, relying on complete or near-complete exploration via two-parameter scans (images) of the device response, quickly become impractical with increasing numbers of gates. Here we propose to circumvent this challenge by introducing a measurement technique relying on one-dimensional projections of the device response in the multidimensional parameter space. Dubbed the ``ray-based classification (RBC) framework,'' we use this machine learning approach to implement a classifier for QD states, enabling automated recognition of qubit-relevant parameter regimes. We show that RBC surpasses the 82 % accuracy benchmark from the experimental implementation of image-based classification techniques from prior work while reducing the number of measurement points needed by up to 70 %. The reduction in measurement cost is a significant gain for time-intensive QD measurements and is a step forward toward the scalability of these devices. We also discuss how the RBC-based optimizer, which tunes the device to a multiqubit regime, performs when tuning in the two-dimensional and three-dimensional parameter spaces defined by plunger and barrier gates that control the QDs.This work provides experimental validation of both efficient state identification and optimization with machine learning techniques for non-traditional measurements in quantum systems with high-dimensional parameter spaces and time-intensive measurements.

The Chrono-geometrical Structure of Special and General Relativity: a Re-Visitation of Canonical Geometrodynamics

description: A modern re-visitation of the consequences of the lack of an intrinsic notion of instantaneous 3-space in relativistic theories leads to a reformulation of their kinematical basis emphasizing the role of non-inertial frames centered on an arbitrary accelerated observer. In special relativity the exigence of predictability implies the adoption of the 3+1 point of view, which leads to a well posed initial value problem for field equations in a framework where the change of the convention of synchronization of distant clocks is realized by means of a gauge transformation. This point of view is also at the heart of the canonical approach to metric and tetrad gravity in globally hyperbolic asymptotically flat space-times, where the use of Shanmugadhasan canonical transformations allows the separation of the physical degrees of freedom of the gravitational field (the tidal effects) from the arbitrary gauge variables. Since a global vision of the equivalence principle implies that only global non-inertial frames can exist in general relativity, the gauge variables are naturally interpreted as generalized relativistic inertial effects, which have to be fixed to get a deterministic evolution in a given non-inertial frame. As a consequence, in each Einstein's space-time in this class the whole chrono-geometrical structure, including also the clock synchronization convention, is dynamically determined and a new approach to the Hole Argument leads to the conclusion that "gravitational field" and "space-time" are two faces of the same entity. This view allows to get a classical scenario for the unification of the four interactions in a scheme suited to the description of the solar system or our galaxy with a deperametrization to special relativity and the subsequent possibility to take the non-relativistic limit.

description: We define the wonderful compactification of an arrangement of subvarieties. Given a complex nonsingular algebraic variety $Y$ and certain collection $\mathcal{G}$ of subvarieties of $Y$, the wonderful compactification $Y_\mathcal{G}$ can be constructed by a sequence of blow-ups of $Y$ along the subvarieties of the arrangement. This generalizes the Fulton-MacPherson configuration spaces and the wonderful models given by De Concini and Procesi. We give a condition on the order of blow-ups in the construction of $Y_\mathcal{G}$ such that each blow-up is along a nonsingular center.
