description: Obtaining the ability to make informed decisions regarding the operation and maintenance of structures, provides a major incentive for the implementation of structural health monitoring (SHM) systems. Probabilistic risk assessment (PRA) is an established methodology that allows engineers to make risk-informed decisions regarding the design and operation of safety-critical and high-value assets in industries such as nuclear and aerospace. The current paper aims to formulate a risk-based decision framework for structural health monitoring that combines elements of PRA with the existing SHM paradigm. As an apt tool for reasoning and decision-making under uncertainty, probabilistic graphical models serve as the foundation of the framework. The framework involves modelling failure modes of structures as Bayesian network representations of fault trees and then assigning costs or utilities to the failure events. The fault trees allow for information to pass from probabilistic classifiers to influence diagram representations of decision processes whilst also providing nodes within the graphical model that may be queried to obtain marginal probability distributions over local damage states within a structure. Optimal courses of action for structures are selected by determining the strategies that maximise expected utility. The risk-based framework is demonstrated on a realistic truss-like structure and supported by experimental data. Finally, a discussion of the risk-based approach is made and further challenges pertaining to decision-making processes in the context of SHM are identified.

description: We investigate the weak gravity bounds on the U(1) gauge theory and scalar field theories in various dimensional noncommutative space. Many results are obtained, such as the upper bound on the noncommutative scale $g_{YM}M_p$ for four dimensional noncommutative U(1) gauge theory. We also discuss the weak gravity bounds on their commutative counterparts. For example, our result on 4 dimensional noncommutative U(1) gauge theory reduces in certain limit to its commutative counterpart suggested by Arkani-Hamed et.al at least at tree-level.

Η παρούσα διατριβή, ποσοτικοποιεί την πράσινη, την μπλε και την γκρι συνιστώσα του υδατικού αποτυπώματος των καλλιεργειών της πεδιάδας Θεσσαλονίκης, εφαρμόζοντας δύο μεθόδους υπολογισμού του. Η πρώτη μέθοδος προτάθηκε από τους Hoekstra and Chapagain και η δεύτερη αναπτύχθηκε αργότερα από τους Ridoutt and Pfister ως μία αναθεωρημένη μορφή της πρώτης μεθόδου. Στα ερευνητικά πλαίσια αυτής της διατριβής για τον υπολογισμό του υδατικού αποτυπώματος εφαρμόστηκε μια επέκταση της μεθόδου Hoekstra-Chapagain ενσωματώνοντας στον υπολογισμό της, τις συνιστώσες της τριχοειδούς ανύψωσης και της εδαφικής υγρασίας στην αρχή της βλαστικής περιόδου καθώς επίσης και ένα σενάριο κλιματικής αλλαγής. Η εκτίμηση του υδατικού αποτυπώματος με τη μέθοδο Ridoutt-Pfister έγινε αρχικά χρησιμοποιώντας βιβλιογραφική τιμή για μια από τις παραμέτρους της μεθόδου που είναι ο Δείκτης Πίεσης Νερού (WSI). Σε μια προσπάθεια όμως ο δείκτης αυτός να αντικατοπτρίσει όσο το δυνατόν περισσότερο τις πραγματικές συνθήκες της υπό μελέτη περιοχής έγινε υπολογισμός του Δείκτη Πίεσης Νερού, λαμβάνοντας υπόψη κλιματικά δεδομένα και δεδομένα υδατικής διαθεσιμότητας της συγκεκριμένης περιοχής. Αξιοποιώντας τις πληροφορίες του ΥΑ των καλλιεργειών μπορεί να δρομολογηθεί η παραγωγή προς λιγότερο υδροβόρες και λιγότερο ρυπογόνες κατευθύνσεις εξασφαλίζοντας την ποσοτική και ποιοτική διαφύλαξη των υδατικών πόρων.
description: Aim of this paper is the water footprint (WF) estimation of crops in the plain of Thessaloniki. This study quantifies the green, blue and grey water footprint of growing crops in Thessaloniki plain by applying two methods for the calculation of water footprint. The first suggested by Hoekstra and Chapagain and the second which is a revised version of the first, by Ridoutt and Pfister. In the research part of this study was applied an extension of Hoekstra-Chapagain method integrating to the calculation the components of soil moisture and capillary rise. Furthermore, by Hoekstra-Chapagain method calculated the water footprint of growing crops under one climate change scenario. The estimation of the water footprint by Ridoutt-Pfister method was made initially by using a literature value for one of the parameters which is the Water Stress Index (WSI). However, in an attempt the WSI to reflect as possible the actual conditions of the study area, this parameter was calculated, based on climate data and availability of water data in the region. Utilizing information of the water footprint of crops we can infer which activities consume large quantities of water and where it is possible replacing them with other less demanding in order to implement the proper management of water resources.

description: The emergence of quantum technologies is heating up the debate on quantum supremacy, usually focusing on the feasibility of looking good on paper algorithms in realistic settings, due to the vulnerability of quantum systems to myriad sources of noise. In this vein, an interesting example of quantum pseudo-telepathy games that quantum mechanical resources can theoretically outperform classical resources is the Magic Square game (MSG), in which two players play against a referee. Due to noise, however, the unit winning probability of the players can drop well below the classical limit. Here, we propose a timely and unprecedented experimental setup for quantum computation with quantum dots inside optical cavities, along with ancillary photons for realizing interactions between distant dots to implement the MSG. Considering various physical imperfections of our setup, we first show that the MSG can be implemented with the current technology, outperforming the classical resources under realistic conditions. Next, we show that our work gives rise to a new version of the game. That is, if the referee has information on the physical realization and strategy of the players, he can bias the game through filtered randomness and increase his winning probability. We believe our work contributes to not only quantum game theory, but also quantum computing with quantum dots.

Marine Drive, North Vancouver : Can it become pedestrian oriented?

Publisher: name: University of British Columbia

description: Mixed land use policies are being recognized as a way to help ameliorate the ill s of single land use precincts. Policies which perpetuate these precincts are inflexible, unresponsive to change, and are beginning to make North American cities sterile. Further, economic and ecological pressures dictate that we begin to reconfigure urban space. Mixed land uses and compact form must replace segregation and urban sprawl. Mixed commercial and residential, pedestrian-oriented corridors offer one way of dealing with this issue. Mixed use commercial/residential corridors have attracted interest in the Planning field. In the District of North Vancouver Planners and community members wish to explore the possibility of transforming the municipality's Marine Drive corridor into a lively and attractive, pedestrian friendly, mixed-used commercial street. Recent amendments to the Official Community Plan suggest that the corridor is undergoing changes. However, there is a question as to whether or not Marine Drive would make a viable pedestrian-oriented commercial corridor. This thesis investigates potential for pedestrian orientation along Marine Drive. Two of Vancouver's mixed-use commercial corridors were studied in order to discern the ingredients necessary for success. Analysis focuses on history and policy initiatives, as well as current zoning and surrounding developments. Next, Marine Drive is studied. Evidence suggests that attempting to transform Marine Drive into a pedestrian- oriented, lively, mixed commercial and residential corridor is premature, and may be difficult to achieve in the future. General North Shore commercial and geographic characteristics and specific conditions along Marine Drive are not favourable. However, i t may be possible to begin transforming Pemberton Avenue (an important Marine Drive cross street) into a pedestrian-oriented corridor.

description: We present the design of, and a first analysis of data from, the atmospheric seeing monitor at the Australia Telescope Compact Array (ATCA). The seeing monitor has been operational almost continuously since May 2004 and every 10min delivers a measurement of the atmospheric phase stability at the observatory. Its measurements can be used by observers to help deciding whether it is worth carrying out observations at millimetre wavelengths or whether a longer-wavelength backup project should be observed. We present a statistical analysis of the data recorded since September 2004 to characterize the annual variations in atmospheric path length fluctuations. Our analysis shows that in terms of phase stability, nights in spring, summer, and autumn are as good as, or better than, days in winter. We also find that the data imply that the turbulence in the lower few hundred metres of the atmosphere is predominantly responsible for the atmospheric seeing.

A broad swath of interesting, unexplored parameter space very close to the kinematic limit of the decay is found to be within the reach of a new proposed search. A number of possible roles for $X^{0}$ in past and present epochs can be investigated.

Scaling analysis of finite-system results at half-filling reveals evident breakdown of the sum rule in the regime of large gap at V >> t, while the sum rule appears to recover together with vanishing of the Mott-Hubbard gap.

description: An experiment is performed to demonstrate the temporal distinguishability of a four-photon state and a six-photon state, both from parametric down-conversion. The experiment is based on a multi-photon interference scheme in a recent discovered NOON-state projection measurement. By measuring the visibility of the interference dip, we can distinguish the various scenarios in the temporal distribution of the pairs and thus quantitatively determine the degree of temporal (in)distinguishability of a multi-photon state.
Voyeurism, Anxiety, and the Persistence of Trauma: Diversifying Film Noir in European Cinema

Year: 2011

description: Following up on his 2002 book Film Noir—considered mandatory reading for every student of Hollywood cinema—Andrew Spicer impresses his readers with European Film Noir, a wide-ranging collection of essays by internationally renowned film scholars. The volume is as enlightening as it is accessible, mapping out a territory of films that are usually obscured by their more famous American counterparts. The book’s significance to the field of film studies is twofold. Not only do the essays in this volume carve out the distinctive noir strains in French, British, German, Spanish and Italian cinemas, they also advance an updated understanding of film noir as both a cinematic legacy and an idea that critics have projected onto the past. One of the book’s most compelling insights concerns the fact that European film noir was largely shaped by a common need to work through the traumatic experience of war.

description: The formation and evolution of light elements in the Universe act as important cosmological constraints. It has long been assumed that the oldest stars of the Galaxy display the primordial Li abundance in their outer layers, although studies of stellar physics have proven that this abundance must have decreased with time. The primordial Li abundance deduced from the observations of the cosmic background is larger than the maximum observed in these stars. Recent observations have given evidence of a large Li abundance dispersion in very metal-poor stars. Many of these stars are carbon-rich, the carbon-enhanced metal-poor (CEMP) stars. We address the general question of the observed abundances in metal-poor stars and we focus our study on the case of CEMP-s stars. We study how the accretion of the wind of stellar companions, especially asymptotic giant branch stars, modifies the element abundances of metal-poor stars and, in particular Li, taking into account the stellar structure and the hydrodynamic processes that take place after accretion. We compare the results with the observations of Li and heavier elements in these old stars on the main sequence. We use the Montréal/Montpellier stellar evolution code, which includes atomic diffusion and thermohaline convection, to compute the internal structure of the proto-CEMP-s stars and their evolution, from [Fe/H]=-2.31 down to [Fe/H]=-5.45. We study a number of cases that vary according to the masses of the stars, their ages, metallicities, and the distances to their respective companions. We show that the observations of Li dispersion that is associated (or not) with carbon enrichment are well accounted for in terms of accretion on to the metal-poor stars of the winds of stellar companions, with accreted masses smaller than those considered in previous studies. The derived primordial value is in accordance with the cosmological results.

We show that energy and angular distributions for the decay products in the laboratory frame are significantly affected by the tau polarization. Rather strong azimuthal asymmetry about the tau momentum axis is predicted, which may have observable consequences in experiments even with small statistics.

description: In spite of the (correct) common-wisdom statement correlation does not imply causation, a proper employ of time correlations and of fluctuation-response theory allows to understand the causal relations between the variables of a multi-dimensional linear Markov process. It is shown that the fluctuation-response formalism can be used both to find the direct causal links between the variables of a system and to introduce a degree of causation, cumulative in time, whose physical interpretation is straightforward. Although for generic non-linear dynamics there is no simple exact relationship between correlations and response functions, the described protocol can still give a useful proxy also in presence of weak nonlinear terms.
Collapse and Fragmentation of Molecular Cloud Cores. IX. Magnetic Braking of Initially Filamentary Clouds
Creators: name: Boss, Alan P.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The collapse and fragmentation of initially filamentary, magnetic molecular clouds is calculated in three dimensions with a gravitational, radiative hydrodynamics code. The code includes magnetic field effects in an approximate manner: magnetic pressure, tension, braking, and ambipolar diffusion are all modelled. Three types of outcomes are observed: direct collapse and fragmentation into a multiple protostar system, periodic contraction and expansion without collapse, or periodic contraction and expansion leading eventually to collapse. While the models begin their evolution at rest except for the assumed solid-body rotation, they develop weakly supersonic velocity fields as a result of the rebounding prior to collapse. The models show that magnetically-supported clouds subject to magnetic braking can undergo dynamic collapse leading to protostellar fragmentation on scales of 10 AU to 100 AU, consistent with typical binary star separations.

description: The magneto-optical inter-polarization conversions by a layer of quantum dots have been investigated. Various types of polarization response of the sample were observed as a function of external magnetic field and of the orientation of the sample. The full set of experimental dependences is analyzed in terms of a one-step and a two-step model of spin evolution. The angular distribution of the quantum dots over the directions of elongation in the plane of the sample is taken into account in terms of the two models, and the model predictions are compared with experimental observations.

description: We show that antiferromagnetism in lightly (~8 %) Sn-doped CeIn_3 terminates at a critical field μ_0H_c= 42 \pm 2 T. Electrical transport and thermodynamic measurements reveal that the effective mass $m^\ast$ does not diverge, suggesting that cubic CeIn_3 is representative of a critical spin-density wave (SDW) scenario, unlike the local quantum critical points reported in lower-symmetry systems such as CeCu_{6-x}Au_x and YbRh_2Si_{2-x}Ge_x. The existence of a maximum in m* at a lower field μ_0H_x = 30 \pm 1 T may be interpreted as a field-induced crossover from local moment to SDW behavior as the magnitude of the antiferromagnetic order parameter falls below the Fermi bandwidth.

description: Using ab initio calculations, we show that the hidden influence of selection rules on three-phonon scattering can be exposed through anomalous signatures in the pressure ($P$) and temperature ($T$) dependence of the thermal conductivities, $κ$, of certain compounds. Boron phosphide reveals such underlying behavior through an exceptionally sharp initial rise in $κ$ with increasing $P$, which may be the steepest of any material, and also a peak and decrease in $κ$ at high $P$. These features are in stark contrast to the measured behavior for many solids, and occur at experimentally accessible conditions. Similar anomalous behavior is predicted for silicon carbide and other related materials.

description: A symplectic manifold $(M,ω)$ is called {\em (symplectically) uniruled} if there is a nonzero genus zero GW invariant involving a point constraint. We prove that symplectic uniruledness is invariant under symplectic blow-up and blow-down. This theorem follows from a general Relative/Absolute correspondence for a symplectic manifold together with a symplectic submanifold. A direct consequence is that symplectic uniruledness is a symplectic birational invariant. Here we use Guillemin and Sternberg's notion of cobordism as the symplectic analogue of the birational equivalence.

Affordable housing through affirmative zoning
Creators: name: Malong, Julieta M. D.
Publisher: name: University of British Columbia
Year: 2009

description: The delivery of social housing is consistently plagued with problems ranging from reduced budget allocation, scarcity of adequately zoned lands and neighborhood opposition. Though limited, provincial funding is still available in BC. However, land acquisition remains a problem. Municipal governments are recognized to have the influence to increase the amount of land for affordable housing projects through the use of zoning by-laws. This thesis argues that the exclusionary character of the municipal zoning by-law does not encourage the creation of affordable housing units. Amendments to the Municipal Act under Bill 57 which allow BC municipalities to negotiate with developers to set aside some units as affordable through density bonusing and inclusionary zoning do not also guarantee that units can be created. Both strategies are dependent on the performance of the market place. This thesis explores an alternative form of affirmative zoning as a possible municipal initiative that can facilitate the creation of affordable housing units by reviewing governments' activities in affordable housing provision and by looking at Surrey as an illustrative case. The alternative form calls for the amendment of the zoning by-law to include a specific zone for affordable housing and pre-zoning of vacant municipal-owned lands for affordable housing. By adopting this strategy, a municipal government departs from its traditional reactor role. Surrey has demonstrated that in order to adopt affirmative zoning, a municipality has to be governed by a socially-committed council who should bring affordable housing provision as a visible component in the municipal agenda. The case also shows that the process has inherent constraints. The provincial government may prohibit councils from identifying affordable housing as a distinct zone while neighbourhoods can still mount strong opposition against the process. Senior governments may start to "dump" social housing projects in municipalities that have adopted this mechanism. With this mechanism in place, a municipal government may expect to accommodate additional population and consequently, an additional demand on municipal resources and services. However, the adoption of the strategy can provide municipal governments with an alternative option, enhance the planning process, foster public acceptance of affordable housing projects, and shorten the approval process. Two lessons are drawn from this thesis: • municipal resources can be re-directed to facilitate the process of creating affordable housing units and • planners and decision-makers should assume a progressive philosophy, leadership and social commitment to ensure that the strategy works.

description: We propose a class of nodal line semimetals that host an eight-fold degenerate double Dirac nodal line (DDNL) with negligible spin-orbit coupling. We find only 5 of the 230 space groups host the DDNL. The DDNL can be considered as a combination of two Dirac nodal lines, and has a trivial Berry phase. This leads to two possible but completely different surface states, namely, a torus surface state covering the whole surface Brillouin zone and no surface state at all. Based on first-principles calculations, we predict that the hydrogen storage material LiBH is an ideal DDNL semimetal, where the line resides at Fermi level, is relatively flat in energy, and exhibits a large linear energy range. Interestingly, both the two novel surface states of DDNL can be realized in LiBH. Further, we predict that with a magnetic field parallel to DDNL, the Landau levels of DDNL are doubly degenerate due to Kramers-like degeneracy and have a doubly degenerate zero-mode.

The purpose of this dissertation is to search the temporal moral principles and values taught in the New Testament so as the teacher who practices counseling in school for respecting the differences can utilize them effectively. The portrait of Christ as a Master is outlined and we study the way Jesus and His Disciples, emphasizing the Apostle Paul, gave their advice, as it is reflected in the texts of the New Testament. Basic principles of counseling at school are proposed based on the teachings of the New Testament. We study the teachings as we find them in the New Testament for respecting the differences, and finally we study the ways in which our Church exploits these teachings and experience the respect of the differences of each person within its ecclesiastical and the liturgical life.

description: Στην παρούσα εργασία επιχειρείται να σκιαγραφηθούν τα όρια της ελευθερίας της έκφρασης όπως αυτά τίθενται από το ελληνικό Σύνταγμα και την ΕΣΔΑ, σε σχέση με τον περιορισμό του μισαλλόδοξου λόγου που εισάγει ο ν. 927/1979 όπως τροποποιήθηκε με το ν. 4285/2014. Στο πλαίσιο αυτό, περιγράφεται η αξία της ελευθερίας της έκφρασης, η έννοια και οι διακρίσεις του μισαλλόδοξου λόγου καθώς και η έννοια του ιστορικού αναθεωρητισμού ως ειδικότερη μορφή μισαλλόδοξου λόγου. Εντοπίζεται η αρχή της απαγόρευσης των διακρίσεων ως το κοινό νομικό θεμέλιο για την απαγόρευση του λόγου του μίσους και ερευνάται ο τρόπος με τον οποίο ο ν. 927/1979 ποινικοποιεί το μισαλλόδοξο λόγο προς το σκοπό αυτό. Περιγράφονται οι προϋποθέσεις υπό τις οποίες μπορεί θεμιτά να περιορίζεται η ελευθερία της έκφρασης σύμφωνα το Σύνταγμα και την ΕΣΔΑ, αξιοποιώντας τα πορίσματα της εθνικής νομολογίας και, ιδίως, το ερμηνευτικό δεδικασμένο της νομολογίας του ΕΔΔΑ επί υποθέσεων μισαλλόδοξου λόγου. Τέλος, διατυπώνονται κάποια συμπεράσματα ως προς τη συνταγματικότητα και τη συμβατότητα με την ΕΣΔΑ του ν. 927/1979 ως αυτός τροποποιήθηκε με το ν. 4285/2014.
description: This paper attempts to outline the limits of freedom of expression according to the Greek Constitution and the ECHR, concerning the restriction of hate speech envisaged by Law 927/1979 as amended by Law 4285/2014. In this condext, is analysed the value of the freedom of expression, the meaning and the different types of hate speech, as well as historical revisionism, as a particular aspect of hate speech. It is suggested that the benchmark for prohibiting hate speech is the principle of non-discrimination. The way that Law 927/1979 attemps to uphold this principle through criminalization of hate speech, is also studied. The conditions are described under which freedom of expression can legitimately be restricted according to the Constitution and the ECHR, considering not only the greek case law but also its ECHR counterpart on hate speech cases. Finally, a conclusion is drawn on the constitutionality of Law 927/1979 (as amended by Law 4285/2014) and its compatibility with the ECHR.

description: We report the results of new Hubble Space Telescope imaging of the positions of six ultraluminous X-ray sources (ULXs). Using images in three ACS filters we detect good candidate counterparts to four out of six ULXs, with one more possible detection, and observed magnitudes in the range m ~ 22 - 26 in the F606W filter. The extinction-corrected colours and absolute magnitudes vary from source to source, even after correcting for additional extinction in the host galaxy, and only one counterpart is readily explained as an OB star. Nevertheless, these counterparts are decent candidates for future follow-up in pursuit of dynamical mass constraints on the likely black holes powering these sources.

description: A complete understanding of solar radio bursts requires developing numerical techniques which can connect large-scale activities with kinetic plasma processes. As a starting point, this study presents a numerical scheme combining three different techniques: (1) extrapolation of magnetic field overlying a specific active region in order to derive the background field, (2) guiding-center simulation of dynamics of millions of particles within a selected loop to reveal the integral velocity distribution function (VDF) around certain sections of the loop, and (3) particle-in-cell (PIC) simulation of kinetic instabilities driven by energetic electrons initiated by the obtained distributions. Scattering effects at various levels (weak, moderate, and strong) due to wave/turbulence-particle interaction are considered using prescribed time scales of scattering. It was found that the obtained VDFs contain strip-like and loss-cone features with positive gradient, and both features are capable of driving electron cyclotron maser emission (ECME), which is a viable radiation mechanism for some solar radio bursts, in particular, solar radio spikes. The strip-like feature is important in driving the harmonic X mode, while the loss-cone feature can be important in driving the fundamental X mode. In the weak-scattering case, the rate of energy conversion from energetic electrons to X2 can reach up to ~2.9 * 10^-3 Ek0, where Ek0 is the initial kinetic energy of energetic electrons. The study demonstrates a novel way of exciting X2 mode in the corona during solar flares, and provides new sight into how escaping radiation can be generated within a coronal loop during solar flares.

description: We analyze the centralizer of the Macdonald difference operator in an appropriate algebra of Weyl group invariant difference operators. We show that it coincides with Cherednik's commuting algebra of difference operators via an analog of the Harish-Chandra isomorphism. Analogs of Harish-Chandra series are defined and realized as solutions to the system of basic hypergeometric difference equations associated to the centralizer algebra. These Harish-Chandra series are then related to both Macdonald polynomials and Chalykh's Baker-Akhiezer functions.

description: Glitch is supposed to be a useful probe into pulsar's interior, but the underlying physics remains puzzling. The glitch activity may reflect a lower limit of the crustal moment of inertia in conventional neutron star models. Nevertheless, its statistical feature could also be reproduced in the strangeon star model, which is focused here. We formulate the glitch activity of normal radio pulsars under the framework of starquake of solid strangeon star model, the shear modulus of strangeon matter is constrained to be $μ\simeq 3\times10^{34}~\rm erg/cm^{3}$, consistent with previous work. Nevertheless, about ten times the shift in oblateness accumulated during glitch interval is needed to fulfill the statistical observations. The fact that typical glitch sizes of two rapidly evolving pulsars (the Crab pulsar and PSR B0540-69) are about two orders of magnitude lower than that of the Vela pulsar, significantly lower than the oblateness change they can supply, indicates probably that only a part of oblateness change is relieved when a pulsar is young. The unreleased oblateness and stress may relax as compensation in the following evolution. The small glitch sizes and low glitch activity of the Crab pulsar can be explained simultaneously in this phenomenological model. Finally, we obtain energy release to be $ΔE\sim 2.4\times 10^{40}~\rm erg$ and $ΔE\sim 4.2\times 10^{41}~\rm erg$ for typical glitch size of $Δν/ν\sim 10^{-6}$ (Vela-like) and $\sim 10^{-8}$ (Crab-like). The upcoming SKA may test this model through the energy release and the power-law relation between the reduced recovery coefficient $Q/|\dotν|^{1/2}$ and $Δν/ν$.

Coupling Feasibility Pump and Large Neighborhood Search to solve the Steiner team orienteering problem

description: The Steiner Team Orienteering Problem (STOP) is defined on a digraph in which arcs are associated with traverse times, and whose vertices are labeled as either mandatory or profitable, being the latter provided with rewards (profits). Given a homogeneous fleet of vehicles M, the goal is to find up to m = |M| disjoint routes (from an origin vertex to a destination one) that maximize the total sum of rewards collected while satisfying a given limit on the route's duration. Naturally, all mandatory vertices must be visited. In this work, we show that solely finding a feasible solution for STOP is NP-hard and propose a Large Neighborhood Search (LNS) heuristic for the problem. The algorithm is provided with initial solutions obtained by means of the matheuristic framework known as Feasibility Pump (FP). In our implementation, FP uses as backbone a commodity-based formulation reinforced by three classes of valid inequalities. To our knowledge, two of them are also introduced in this work. The LNS heuristic itself combines classical local searches from the literature of routing problems with a long-term memory component based on Path Relinking. We use the primal bounds provided by a state-of-the-art cutting-plane algorithm from the literature to evaluate the quality of the solutions obtained by the heuristic. Computational experiments show the efficiency and effectiveness of the proposed heuristic in solving a benchmark of 387 instances. Overall, the heuristic solutions imply an average percentage gap of only 0.54% when compared to the bounds of the cutting-plane baseline. In particular, the heuristic reaches the best previously known bounds on 382 of the 387 instances. Additionally, in 21 of these cases, our heuristic is even able to improve over the best known bounds.

description: The planned generation of lasers and heavy ion colliders renews the hope to see electron-positron pair creation in strong classical fields (so called spontaneous pair creation). This adiabatic relativistic effect has however not been described in a unified manner. We discuss here the theory of adiabatic pair creation yielding the momentum distribution of scattered pairs in overcritical fields. Our conclusion about the possibility of adiabatic pair creation is different from earlier predictions for laser fields.

description: As an important method of handling potential uncertainties in numerical simulations, ensemble simulation has been widely applied in many disciplines. Visualization is a promising and powerful ensemble simulation analysis method. However, conventional visualization methods mainly aim at data simplification and highlighting important information based on domain expertise instead of providing a flexible data exploration and intervention mechanism. Trial-and-error procedures have to be repeatedly conducted by such approaches. To resolve this issue, we propose a new perspective of ensemble data analysis using the attribute variable dimension as the primary analysis dimension. Particularly, we propose a variable uncertainty calculation method based on variable spatial spreading. Based on this method, we design an interactive ensemble analysis framework that provides a flexible interactive exploration of the ensemble data. Particularly, the proposed spreading curve view, the region stability heat map view, and the temporal analysis view, together with the commonly used 2D map view, jointly support uncertainty distribution perception, region selection, and temporal analysis, as well as other analysis requirements. We verify our approach by analyzing a real-world ensemble simulation dataset. Feedback collected from domain experts confirms the efficacy of our framework.

description: The presentation presents the analysis of Russian-speaking identities’ vision and understanding of the war in Ukraine as well as the way it has affected their lives. This armed conflict has become a tragic stage for the Ukrainian people. It has also become a turning point for Russian-speaking identities both living in the RF and immigrating or living in Europe and Great Britain. So, the objective of this article is to address the problem of mental stereotypes and their reconsideration as well as behavioural changes in Russian-speaking identities with the war in Ukraine. 

This presentation reports on research conducted as part of "Connective digital memory in borderlands: a mixed-methods study of cultural identity, heritage communication and digital curation on social networks". The Connective project is funded by the European Social Fund under grant agreement 09.3.3-LMT-K-712-17-0027 with the Research Council of Lithuania (LMTLT).
