description: We study the transport of cold fermionic atoms trapped in optical lattices in the presence of artificial Abelian or non-Abelian gauge potentials. Such external potentials can be created in optical lattices in which atom tunneling is laser assisted and described by commutative or non-commutative tunneling operators. We show that the Hall-like transverse conductivity of such systems is quantized by relating the transverse conductivity to topological invariants known as Chern numbers. We show that this quantization is robust in non-Abelian potentials. The different integer values of this conductivity are explicitly computed for a specific non-Abelian system which leads to a fractal phase diagram.

description: We put forward a new fiber optic sensor for measuring linear velocity with picometer/second sensitivity with Weak-value amplification based on generalized Sagnac effect [Phys. Rev. Lett.\textbf{93}, 143901(2004)].The generalized Sagnac effect was first introduced by Yao et al, which included the Sagnac effect of rotation as a special case and suggested a new fiber optic sensor for measuring linear motion with nanoscale sensitivity. By using a different scheme to perform the Sagnac interferometer with the probe in momentum space, we have demonstrated the new weak measure protocol to detect the linear velocity by amplifying the phase shift of the generalized Sagnac effect. Given the maximum incident intensity of the initial spectrum, the detection limit of the intensity of the spectrometer, we can theoretically give the appropriate pre-selection, post-selection, and other optical structures before the experiment. Our numerical results show our scheme with Weak-value amplification is effective and feasible to detect linear velocity with picometer/second sensitivity which is three orders of magnitude smaller than the result $ν$=4.8 $\times$ $10^{-9}$ m/s obtained by generalized Sagnac effect with same fiber length.

description: We employ the cluster slave-spin method to investigate systematically the ground state properties of the Hubbard model on a square lattice with doping $δ$ and coupling strength $U$ being its parameters. In addition to a crossover reflected in the behavior of the antiferromagnetic gap $Δ_{\text{AFM}}$, this property can also be observed in the energetics of the cluster slave-spin Hamiltonian -- the antiferromagnetism at small $U$ is due to the potential energy gain while that in the strong coupling limit is driven by the kinetic energy gain, which is consistent with the results from the cluster dynamical mean-field theory calculation and the quantum Monte Carlo simulation. We find the interaction $U_{c}$ for the crossover in the AFM state, separating the weak- and strong- coupling regimes, almost remains unchanged upon doping, and it is smaller than the critical coupling strength $U_{\text{Mott}}$ for the first-order metal-insulator Mott transition in the half-filled paramagnetic state. At half-filling, a relationship between the staggered magnetization $M$ and $Δ_{\text{AFM}}$ is established in the small $U$ limit to nullify the Hartree-Fock theory, and a first-order Mott transition in the paramagnetic state is substantiated, which is characterized by discontinuities and hystereses at $U_{\text{Mott}}=10t$. Finally, an overall phase diagram in the $U$-$δ$ plane is presented, which is composed of four regimes: the antiferromagnetic insulator, the antiferromagnetic metal with the compressibility $κ>0$ or $κ<0$, and the paramagnetic metal, as well as three phase transitions: (i) From the antiferromagnetic metal to the paramagnetic metal, (ii) between the antiferromagnetic metal phases with positive and negative $κ$, and (iii) separating the antiferromagnetic insulating phase from the antiferromagnetic metal phase.

description: Several large-scale gravitational wave (GW) interferometers have achieved long term operation at design sensitivity. Questions arise on how to best combine all available data from detectors of different sensitivities for detection, consistency check or veto, localization and waveform extraction. We show that these problems can be formulated using the singular value decomposition (SVD) method. We present techniques based on the SVD method for (1) detection statistic, (2) stable solutions to waveforms, (3) null-stream construction for an arbitrary number of detectors, and (4) source localization for GWs of unknown waveforms.

description: In previous works [physics/0204035, physics/0404052, physics/0509126] a procedure was described for dividing the $3 \times N$-dimensional conformational space of a molecular system into a number of discrete cells, this partition allowed the building of a combinatorial structure from data sampled in molecular dynamics trajectories: the graph of cells, that encodes the set of cells in conformational space that are visited by the system in its thermal wandering. Here we outline a set of procedures for extracting useful information from this structure: 1st) interesting regions in the volume occupied by the system in conformational space can be bounded by a polyhedral cone whose faces are determined empirically from a set of relations between the coordinates of the molecule, 2nd) it is also shown that this cone can be decomposed into a hierarchical set of smaller cones, 3rd) the set of cells in a cone can be encoded by a simple combinatorial sequence.

Year: 2022

description: For almost 15 years, social media have been regularly used during emergencies. One of the most recent, and instructive, examples of its widespread use during a large scale scenario in Europe were the 2013 European floods. Public reporting during the event indicated, and our analysis confirms, that Twitter, Facebook (FB), Google Maps and other services were frequently used by affected citizen and volunteers to coordinate help activities among themselves. We conducted a qualitative analysis of selected emergent volunteer communities in Germany on FB and Twitter among others, and subsequently conducted interviews with FB group founders and activists. Our aim was to analyze the use of social media during this particular event, especially by digital volunteers. Our study illustrates the relevance of social media for German citizens in cases of disaster, focusing especially on the role of the moderator. Our specific emphasis was the embedding of social media in the organizing work done by said volunteers, emphasizing both the patterns of social media use and the challenges that result. We show that different social media were used in different ways: Twitter was used in the main for status updates while FB-pages were mostly intended to provide an overview. FB-groups also coordinated a multitude of activities.

description: We perform an information-theoretical analysis of quantum measurement processes and obtain the global information balance in quantum measurements, in the form of a closed chain equation for quantum mutual entropies. Our balance provides a tight and general entropic information-disturbance trade-off, and explains the physical mechanism underlying it. Finally, the single-outcome case, that is, the case of measurements with post-selection, is briefly discussed.

description: We propose a novel mechanism for creating a qubit based on a tight knot, that is a nano-quantum wire system so small and so cold as to be quantum coherent with respect to curvature-induced effects. To establish tight knots as legitimate candidates for qubits, we propose an effective curvature-induced potential that produces the two-level system and identify the tunnel coupling between the two local states. We propose also a different design of nano-mechanical qubit based on twisted nano-rods. We describe how both devices can be manipulated. Also we outline possible decoherence channels, detection schemes and experimental setups.

The slab is illuminated on one side by a collimated beam and is bounded on the other side by an emitting and partially reflecting ground. We provide expressions for the incident and reflected fluxes on both boundary surfaces, as well as the temperature of the ground and the temperature distribution in the atmosphere, assuming the latter to be in local thermodynamic equilibrium. Tables and curves of the temperature distribution are included for various values of the optical thickness. Finally, semi-infinite atmospheres illuminated from the outside or by sources at infinity will be dealt with.

In vitro modulation of classic II MHC antigen expression by human cerebral endothelium and endothelial cell-lymphocyte interactions by interferons [gamma] and [beta]
Creators: name: Huynh, Hanh Kim
Publisher: name: University of British Columbia
Year: 2009

description: In autoimmune demyelinating disorders of the central nervous system (CNS), the blood-brain-barrier (BBB) becomes permeable to plasma proteins and circulating leukocytes. Studies on Multiple Sclerosis (MS) suggest the involvement of T4⁺ lymphocytes and Ia⁺ macrophages in lesion extension and demyelination. Circulating lymphocytes recognize antigen only when it is complexed with Ia molecules on the surface of antigen presenting cells. Recent studies aiming at defining cell populations in the CNS capable of expressing Ia antigen (Ia Ag) indicate Ia Ag expression by EC, astrocytes, microglia and macrophages in MS lesions, while in experimental allergic encephalomyelitis, Ia Ag expression by brain endothelium has been reported by some, but not other investigators. The role of cerebral endothelium in CNS inflammation, therefore, remains ill defined and rather controversial. The objective of this thesis was to investigate the: 1) Induction of Ia Ag on human brain microvessel endothelial cells (HBMEC) treated with interferons (IFN) γ and β, and 2) modulation of T-lymphocyte adhesion and migration across HBMEC monolayers by IFN- γ and β. To address these issues, an in vitro model of the human BBB was utilized. The results indicate that HBMEC do not constitutively express Ia Ag. Treatment with IFN- γ, not β, results in de novo, polarized expression of Ia Ag. Co-incubation with IFN- β downregulates the IFN γ -induced Ia Ag expression. Treatment with IFN- γ, not β, induces morphological and functional changes of HBMEC associated with increased permeability to macromolecules. IFN- γ induced changes do not appear in cultures incubated with both cytokines. Treatment of HBMEC with IFN- γ upregulates the adhesion and migration of resting and activated T lymphocytes across the monolayers. T-lymphocyte activation alone greatly augments both processes. Treatment with IFN- β has no effect on lymphocyte adhesion/migration, however, the IFN-γ-mediated increase in adhesion/migration is suppressed by IFN- β. MAb blocking studies suggest a direct role of Ia molecules in adhesion/migration. These studies indicate a potentially important role of HBMEC in CNS inflammation and increase our understanding of some of the factors involved in the recruitment of lymphocytes into chronic inflammatory sites in the CNS. Therapeutic interventions utilizing mAbs against HLA-DR molecules as well as the use of cytokines, such as IFN- β, that can suppress IFN-γ-mediated responses, may have considerable therapeutic potential.

description: In this paper we define and study self-similar ranked fragmentations. We first show that any ranked fragmentation is the image of some partition-valued fragmentation, and that there is in fact a one-to-one correspondence between the laws of these two types of fragmentations. We then give an explicit construction of homogeneous ranked fragmentations in terms of Poisson point processes. Finally we use this construction and classical results on records of Poisson point processes to study the small-time behavior of a ranked fragmentation.

description: Precise measurements of the anisotropies in the cosmic microwave background enable us to do an accurate study on the form of the primordial power spectrum for a given set of cosmological parameters. In a previous paper (Shafieloo and Souradeep 2004), we implemented an improved (error sensitive) Richardson-Lucy deconvolution algorithm on the measured angular power spectrum from the first year of WMAP data to determine the primordial power spectrum assuming a concordance cosmological model. This recovered spectrum has a likelihood far better than a scale invariant, or, `best fit' scale free spectra (Δln L = 25 w.r.t. Harrison Zeldovich, and, Δln L = 11 w.r.t. power law with n_s=0.95). In this paper we use Discrete Wavelet Transform (DWT) to decompose the local features of the recovered spectrum individually to study their effect and significance on the recovered angular power spectrum and hence the likelihood. We show that besides the infra-red cut off at the horizon scale, the associated features of the primordial power spectrum around the horizon have a significant effect on improving the likelihood. The strong features are localised at the horizon scale.

Exorcism-seekers: clinical and personality correlates
Creators: name: Buch, Wes
Publisher: name: University of British Columbia
Year: 2009

description: Abstract This study was a case control field investigation of a special population. The psychodiagnostic and personality correlates of 40 Christian Charismatic exorcism-seekers were compared to the correlates of 40 matched c2ntrols and 48 randomly selected controls. The study was guided by a central research question: how do exorcism-seekers differ from similar individuals who do not seek exorcism? Two theoretiäal approaches to demonic possession and exorcism anticipated different answers. A mental illness approach anticipated the report of certain forms of clinical distress among exorcism-seekers. A social role approach anticipated the report of certain personality traits that would facilitate the effective enactment of the demoniac role. Results supported the mental illness approach to demonic possession inasmuch as numerous between-group diagnostic differences achieved statistical significance, especially mood disturbance. The exorcism-seeker’s group produced a modal dependent-avoidant personality disorder profile, although schizoid features best distinguished between exorcism-seekers and control subjects. However, half of the sample did not report significant psychological distress. A cognitive-behavioral model of demonic possession of relevance to both distressed and non-distressed exorcism-seekers was therefore proposed. Treatment implications included a discussion of special treatment problems and collaboration between members of the clergy and the health care professions.

description: The aim of the present thesis was the study of the technological developments as well as the regulation regarding the electrical energy storage systems (EES). Initially, we present the various energy storage technologies which have been developed so far. We examine the advantages and the drawbacks of each technology, as well as their future potential. Then, the different services that the energy storage sector could provide in the electrical system and in the new energy markets are described. The regulation is an important factor for the integration of energy storage systems in these markets. Furthermore, we thoroughly examine the regulatory framework and the developments that have been made in the European Union, as far as the EES are concerned. Finally, we present various data regarding both the current framework regulation and the popular technologies in the storage sector of Greece, and its possible future developments.

description: Studies of the rotation-activity relation of late-type stars are essential to enhance our understanding of stellar dynamos and angular momentum evolution. Photometric observations with space telescopes provide rotation periods even with low amplitudes as well as a wealth of activity diagnostics. Our previous study of the rotation-activity relation based on photometric activity indicators from long cadence K2 data revealed, that, at a critical rotation period of ~10d, the activity level changes abruptly. This phenomenon represents an open problem within the framework of dynamo theory. We have now extended our work to K2 short cadence data to examine a possible influence of the data sampling on the shape of the rotation-activity relation, in particular with respect to the different sensitivity to the detection of stellar flares. Our sample comprises 56 bright and nearby M dwarfs observed by K2 during campaigns C0-C18 in long and short cadence mode. In my poster I will show the results of our K2 study with a special focus on stellar flares. I will show how a higher data cadence improves the detection and analysis of such events. The analysis of the short cadence light curves results in a 4.6 times higher flare rate than the long cadence data. We confirm in the short cadence data the abrupt change of the activity level in the rotation-activity relation at a critical period of ~10d. This change is most drastic in the flare duration and the flare frequency for short cadence data. Our flare studies revealed that the highest flare rates are not found among the fastest rotators and that the stars with the highest flare rates do not show the most energetic flares. Finally, we found a ~2 times larger superflares frequency for the fast rotating M stars than for solar-like stars in the same period range.

description: Σκοπός της διατριβής ήταν η μελέτη των ορίων της εξορυκτικής δραστηριότητας από λιγνίτη και της παραγωγής ηλεκτρικής ενέργειας από λιγνίτη στον ενεργειακό άξονα της Περιφέρειας Δυτικής Μακεδονίας. Εξετάσαμε την ευρωπαΐκη πολιτική και την σχέση της με την βιωσιμότητα της λιγνιτικής παραγωγής. Στη συνέχεια παρουσιάσαμε αναλυτικά το ισχύον καθεστώς αγοράς ηλεκρικής ενέργειας και την εξέλιξη της απελευθέρωσης της. Ακόμη αναφερθήκαμε αναλυτικά στις εθνικές υποχρεώσεις στον τομέα της ενέργειας και μας απασχόλησε η δυείσδυση των Ανανεώσιμων Πηγων Ενέργειας στην ηλεκτροπαραγωγή. Ένα άλλο θέμα που θίξαμε ήταν οι απόφασεις των ευρωπαΐκών οργάνων για τον λιγνίτη σε σχέση με την έννοια του αναταγωνισμού. Ασχοληθήκαμε επιπλέον με την εθνική στρατηγική συμμόρφωσης στις ευρωπαΐκές απαιτήσεις για την πρόσβαση των ιδιωτών στην εκμετάλλευση του λιγνίτη, τα διαρθρωτικά μέτρα για την κατάργηση του μονοπωλίου της Δημόσιας Επιχείρησης Ηλεκτρισμού στον λιγνίτη και εξετάσαμε την δυνατότητα πώλησης μονάδων παραγωγής ηλεκτρικής ενέργειας από λιγνίτη και εκμετάλλευσης των ορυχείων λιγνίτη από ιδιώτες επενδυτές.
description: The aim of the present thesis was the study of the sustainability limits of the separation of mining lignite activity and the production of lignite electricity in the Western Macedonia energy axis. We examined the European policy and its relation to the sustainability of lignite production. Then we presented in detail the current electricity market and the evolution of its liberation. Furthermore, we analyzed our national energy obligations and we examined the penetration of Renewable Energy Sources into electricity production.We also examined the decisions by European institutions to lignite in relation to the meaning of competition. Another aim of this study was to examine the national strategy compliance to European requirements for private access to lignite, the structural measures for the abolition of the monopoly in lignite by Public Power Corporation and the possibility of selling power plants and giving exploitation of lignite mines to private investors.

description: We show how the Landau-Pomeranchuk-Migdal effect on photon production rates in a quark-gluon plasma can be derived via the usual Boltzmann equation. To do this, we first derive the electromagnetic polarization tensor using linear response theory, and then formulate the Boltzmann equation including the collisions mediated by soft gluon exchanges. We then identify the resulting expression for the production rate with that obtained by the field-theoretic formalism recently proposed by Arnold, Moore and Yaffe. To illustrate the LPM effect we solve the Boltzmann equation in the diffusion approximation.
description: 17 pages, 4 figures Minor rewriting. In particular, the specific small angle behavior of the collision term involved in the LPM effect is better explained. Version accepted for publication in Physics Letters B

description: Σκοπός της διατριβής ήταν η μελέτη της ευρωπαϊκής πολιτικής για την επίτευξη της ασφάλειας εφοδιασμού σε φυσικό αέριο. Αρχικά, αναφέρθηκα στις ενεργειακές κρίσεις που σημειώθηκαν στην Ευρώπη τα έτη 2006, 2009 και 2016 – 2017 και έπειτα στην Οδηγία 2004/67/ΕΚ που υιοθέτησε η Ευρωπαϊκή Ένωση. Στη συνέχεια αναλύθηκε ο Κανονισμός 994/2010, ο οποίος κατήργησε την ανωτέρω Οδηγία, ενώ αμέσως μετά παρατέθηκαν οι αγωγοί φυσικού αερίου που διασχίζουν την Ευρώπη. Ακόμη, αναλύθηκε η μεταφορά υγροποιημένου φυσικού αερίου με πλοία LNG τόσο σε διεθνές και ευρωπαϊκό επίπεδο όσο και σε εθνικό. Ένα άλλο θέμα που θίχτηκε ήταν οι Συνεργασίες που έχουν συναφθεί και τα Προγράμματα που έχουν υιοθετηθεί εκ μέρους της Ευρωπαϊκής Ένωσης για το Φυσικό Αέριο. Τέλος, έγινε μια εκτενής αναφορά στην ελληνική αγορά του φυσικού αερίου και συγκεκριμένα στην ασφάλεια εφοδιασμού του φυσικού αερίου σε εθνικό επίπεδο.
description: The aim of the present thesis was the study of European policy for security of gas supply. First of all, I examined the energy crises that happened in Europe in 2006, 2009 and 2016 – 2017 and then I examined the Directive 2004/67/EU which was adopted by European Union. Afterwards, Regulation 994/2010 was analysed, which repealed the Directive above and after that, gas pipelines among Europe were quoted. Moreover, I examined the transportation of liquefied natural gas with ships LNG on international, European and national level. Another issue that was broached was the cooperations were contracted and the plans were adopted about gas by European Union. At the end, I expounded on the greek gas market and in particular on security of gas supply in Greece.

description: Networks of genetic expression can be modelled by hypergraphs with the additional structure that real coefficients are given to each vertex-edge incidence. The spectra, i.e. the multiset of the eigenvalues, of such hypergraphs, are known to encode structural information of the data. We show how these spectra can be used, in particular, in order to give an estimation of cellular redundancy, a novel measure of gene expression heterogeneity, of the network. We analyze some simulated and real data sets of gene expression for illustrating the new method proposed here.
Metric gravity theories and cosmology. I. Physical interpretation and viability

description: We critically review some concepts underlying current applications of gravity theories with Lagrangians depending on the full Riemann tensor to cosmology. We argue that it is impossible to reconstruct the underlying Lagrangian from the observational data: the Robertson-Walker spacetime is so simple and "flexible" that any cosmic evolution may be fitted by infinite number of Lagrangians. Confrontation of a solution with the astronomical data is obstructed by the existence of many frames of dynamical variables and the fact that initial data for the gravitational triplet depend on which frame is minimally coupled to ordinary matter. Prior to any application it is necessary to establish physical contents and viability of a given gravity theory.

Developing conceptual frameworks for structuring legal knowledge to build knowledge-based systems
Creators: name: Deedman, Galvin Charles
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation adopts an interdisciplinary approach to the field of law and artificial intelligence. It argues that the conceptual structuring of legal knowledge within an appropriate theoretical framework is of primary importance when building knowledge-based systems. While technical considerations also play a role, they must take second place to an in-depth understanding of the law. Two alternative methods of structuring legal knowledge in very different domains are used to explore the thesis. A deep-structure approach is used on nervous shock, a rather obscure area of the law of negligence. A script-based method is applied to impaired driving, a well-known part of the criminal law. A knowledge-based system is implemented in each area. The two systems, Nervous Shock Advisor (NSA) and Impaired Driving Advisor (IDA), and the methodologies they embody, are described and contrasted. In light of the work undertaken, consideration is given to the feasibility of lawyers without much technical knowledge using general-purpose tools to build knowledge-based systems for themselves.

description: We consider partially observable Markov decision processes (POMDPs), that are a standard framework for robotics applications to model uncertainties present in the real world, with temporal logic specifications. All temporal logic specifications in linear-time temporal logic (LTL) can be expressed as parity objectives. We study the qualitative analysis problem for POMDPs with parity objectives that asks whether there is a controller (policy) to ensure that the objective holds with probability 1 (almost-surely). While the qualitative analysis of POMDPs with parity objectives is undecidable, recent results show that when restricted to finite-memory policies the problem is EXPTIME-complete. While the problem is intractable in theory, we present a practical approach to solve the qualitative analysis problem. We designed several heuristics to deal with the exponential complexity, and have used our implementation on a number of well-known POMDP examples for robotics applications. Our results provide the first practical approach to solve the qualitative analysis of robot motion planning with LTL properties in the presence of uncertainty.

description: We study the possibility of Late Forming Dark Matter (LFDM), where a scalar field, previously trapped in a metastable state by thermal or finite density effects, begins to oscillate near the era matter-radiation equality about its true minimum. Such a theory is motivated generally if the dark energy is of a similar form, but has not yet made the transition to dark matter, and, in particular, arises automatically in recently considered theories of neutrino dark energy. If such a field comprises the present dark matter, the matter power spectrum typically shows a sharp break at small, presently nonlinear scales, below which power is highly suppressed and previously contained acoustic oscillations. If, instead, such a field forms a subdominant component of the total dark matter, such acoustic oscillations may imprint themselves in the linear regime.

description: Magnetic field source localization and imaging happen at different scales. The sensing baseline ranges from meter scale such as magnetic anomaly detection, centimeter scale such as brain field imaging to nanometer scale such as the imaging of magnetic skyrmion and single cell. Here we show how atomic vapor cell can be used to realize a baseline of 109.6 μm with a magnetic sensitivity of 10pT/sqrt(Hz)@0.6-100Hz and a dynamic range of 2062-4124nT.We use free induction decay (FID) scheme to suppress low-frequency noise and avoid scale factor variation for different domains due to light non-uniformity. The measurement domains are scanned by digital micro-mirror device (DMD). The currents of 22mA, 30mA, 38mA and 44mA are applied in the coils to generate different fields along the pumping axis which are measured respectively by fitting the FID signals of the probe light. The residual fields of every domain are obtained from the intercept of linearly-fitting of the measurement data corresponding to these four currents. The coil-generated fields are calculated by deducting the residual fields from the total fields. The results demonstrate that the hole of shield affects both the residual and the coil-generated field distribution. The potential impact of field distribution measurement with an outstanding comprehensive properties of spatial resolution, sensitivity and dynamic range is far-reaching. It could lead to capability of 3D magnetography for small stuffs and/or organs in millimeter or even smaller scale.
