description: An ability of different molecular potentials to reproduce the properties of 2D molybdenum disulphide polymorphs is examined. Structural and mechanical properties, as well as phonon dispersion of the 2H, 1T and 1T' single-layer MoS2 (SL MoS2) phases, were obtained using density functional theory (DFT) and molecular statics calculations (MS) with Stillinger-Weber, REBO, SNAP, and ReaxFF potentials. Quantitative systematic comparison and discussion of the results obtained are reported.

description: No abstracts are to be cited without prior reference to the author. A new analytical approach to fish growth dynamics (Growth curve modeling, GCM), has been developed at the Aquaculture Laboratory of the MRI in Iceland. GCM-modeling is based on the analysis of growth trajectory and links larval- to long term growth performance. The method was initially developed for Atlantic cod (Gadus morhua) but can arguably be applied to all fish species, creating a new perspective on the underlying growth dynamics of fishes. GCM-modeling shows how the long-term growth potential can be traced back to the initial larval growth performance and how the early larval benchmark sizes are systematically reflected throughout the later juvenile- and adult life stages. GCM-modeling further shows how the life-span is divided into consecutive stages with fixed growth potential and how the potential maximum size of the fish is already fixed at the larval stage. When applied to historical data from the Icelandic cod stock, GCM-modeling reveals a previously overlooked fluctuation pattern in cohort growth rates.

description: This dissertation attempts the analytical examination of a part of the ground stone tool assemblage retrieved from Toumpa Kremastis Koiladas, a Late Neolithic site in Northern Greece. The main objective is to explore the various aspects of ground stone lithics, as part of the material culture with multiple functions and meanings, alongside the investigation into the different stages of their life cycle, from the production and use to their final disposal. The study of this material focuses on its particular context, that of a non-domestic space, which is located outside a settlement’s residential area and incorporates a large number of subsurface features, pits and ditches, containing anthropogenic deposits. The discussion of the findings suggest the existence of cultural activities that may have resulted in a differentiated treatment of specific artifacts which bear a common final destination - their disposal in the pits. In fact, specific tool categories are characterized by a very high degree of fragmentation, while specific artifacts exhibit signs of intentional breakage, suggesting the possible symbolic aspect of the ending of their cycle of life and their “burial” into the pits.

description: We study the evolution of a qubit evolving according to the Schrödinger equation with a Hamiltonian containing noise terms, modeled by random diagonal and off-diagonal matrix elements. We show that the noise-averaged qubit density matrix converges to a final state, in the limit of large times $t.$ The convergence speed is polynomial in $1/t$, with a power depending on the regularity of the noise probability density and its low frequency behaviour. We evaluate the final state explicitly. We show that in the regimes of weak and strong off-diagonal noise, the process implements the dephasing channel in the energy- (localized) and the delocalized basis, respectively.

description: Current-induced spin polarization (CISP) is rederived in ballistic spin-orbit-coupled electron systems, based on equilibrium statistical mechanics. A simple and useful picture is correspondingly proposed to help understand the CISP and predict the polarization direction. Nonequilibrium Landauer-Keldysh formalism is applied to demonstrate the validity of the statistical picture, taking the linear Rashba-Dresselhaus [001] two-dimensional system as a specific example. Spin densities induced by the CISP in semiconductor heterostructures and in metallic surface states are compared, showing that the CISP increases with the spin splitting strength and hence suggesting that the CISP should be more observable on metal and semimetal surfaces due to the discovered strong Rashba splitting. An application of the CISP designed to generate a spin-Hall pattern in the inplane, instead of the out-of-plane, component is also proposed.

Aerobic membrane biological reactor treatment of recirculated mechanical newsprint whitewater at high temperatures
Creators: name: Tardif, Olivier
Publisher: name: University of British Columbia
Year: 2009

description: The membrane biological reactor (MBR) is a robust and stable biological treatment process which integrates biological oxidation with ultrafiltration for treating wastewaters. A lab scale MBR consisting of a 10 L aerobic reactor, a cross-flow tubular ultrafiltration unit (molecular weight cut-off = 75 kDaltons) and a progressive cavity pump was operated at temperatures ranging from 40 to 55°C, hydraulic retention times (HRT) of 2.8, 1.1 or 0.7 days, a solids retention time of 25 days and a transmembrane pressure of 79 kPa to treat a synthetic closed-mill mechanical newsprint Whitewater. The mixed-liquor volatile suspended solids concentration in the MBR varied with the operating conditions, ranging from 2 to 9 g/L. In another study, the effectiveness of the ultrafiltration component of the MBR alone was investigated. The synthetic Whitewater was ultrafiltered to a concentration factor of 37 using the ultrafiltration unit at a transmembrane pressure of 69 kPa and a cross-flow velocity of 1.7 m/s (same velocity as the MBR). These two treatment processes were assessed for the removal efficiency of total solids (TS), total dissolved solids (TDS), total chemical oxygen demand (TCOD), dissolved chemical oxygen demand (DCOD), dissolved organic carbon (DOC), colour, cationic demand, resin acids (RA) and fatty acids (FA). The MBR achieved similar removal efficiencies for all operating temperatures and hydraulic retention times. It was particularly effective at removing FA (100% removal), RA (average removal > 98%), TCOD (82% average removal), DCOD (78% average removal) and DOC (76% average removal). The reduction of the Whitewater cationic demand was good (64% average removal). The average removal efficiencies for TS (36%) and TDS (27%) were fair, while the MBR was ineffective at removing colour (-5% average removal). Ultrafiltration alone was not nearly as effective at removing the target contaminants from the synthetic Whitewater. The high removal efficiencies of RFA achieved with the MBR may be due to the fact that RFA have a tendency to be adsorbed by the biosolids, which are retained by the ultrafiltration membrane. This and other inherent advantages of the MBR suggest much potential for this process in treating recirculated Whitewater internally in pulp and paper mills.

description: A particle dynamics-based hybrid model, consisting of monodisperse spherical solid particles and volume-averaged gas hydrodynamics, is used to study traveling planar waves (one-dimensional traveling waves) of voids formed in gas-fluidized beds of narrow cross sectional areas. Through ensemble-averaging in a co-traveling frame, we compute solid phase continuum variables (local volume fraction, average velocity, stress tensor, and granular temperature) across the waves, and examine the relations among them. We probe the consistency between such computationally obtained relations and constitutive models in the kinetic theory for granular materials which are widely used in the two-fluid modeling approach to fluidized beds. We demonstrate that solid phase continuum variables exhibit appreciable ``path dependence'', which is not captured by the commonly used kinetic theory-based models. We show that this path dependence is associated with the large rates of dilation and compaction that occur in the wave. We also examine the relations among solid phase continuum variables in beds of cohesive particles, which yield the same path dependence. Our results both for beds of cohesive and non-cohesive particles suggest that path-dependent constitutive models need to be developed.

description: We report on a direct visualization of coherent destruction of tunneling (CDT) of light waves in a double well system which provides an optical analog of quantum CDT as originally proposed by Grossmann, Dittrich, Jung, and Hanggi [Phys. Rev. Lett. {\bf 67}, 516 (1991)]. The driven double well, realized by two periodically-curved waveguides in an Er:Yb-doped glass, is designed so that spatial light propagation exactly mimics the coherent space-time dynamics of matter waves in a driven double-well potential governed by the Schrödinger equation. The fluorescence of Er ions is exploited to image the spatial evolution of light in the two wells, clearly demonstrating suppression of light tunneling for special ratios between frequency and amplitude of the driving field.

description: No abstracts are to be cited without prior reference to the author. This work outlines the development and application of a new prototype zoning scheme designed specifically and tested for Scottish waters using a Geographical Information System (GIS). The primary aim was to devise a large-scale, ecosystem-based zoning approach for managing activities within Scotland’s marine environment. In this zoning scheme areas are designated within different zones according to a combination of both their ecological features and existing management mechanisms for any activities taking place. For each of the different zones a series of goals, objectives and strategies have been devised to represent the desired outcomes for those areas. This prototype zoning scheme aims to facilitate the delivery of long-term protection to the marine environment, treating areas as whole ecosystems while still enabling a diverse array of activities to take place in a sustainable manner.
La vita consacrata nella Scrittura

description: L’A. sostiene che la vita consacrata trova la sua ragion d’essere sostanziale nel concetto
di alleanza che esclude ogni tipo di contrattazione con Dio presente nella cosiddetta
religiosità. Essa nasce dalla iniziativa di Dio, si nutre di gratuità e si conclude nella
gratuità. La vita consacrata si radica nel dono battesimale che attinge tutti i battezzati
e fiorisce in dispertitae linguae grazie all’opera dello Spirito Santo permettendo a
tutti di conseguire il fine (telos) della vita cristiana attraverso dei voti. Non si dovrebbe
parlare mai di un di più del consacrato rispetto al battezzato, ma semplicemente di
idiorytmia che evidenzia l’adesione personale, con libera scelta (proairesis), al corpo
Cristo nella diversità delle sue membra. Di conseguenza si dovrebbero superare – secondo
l’A. – le tradizionali distinzioni tra consigli e precetti, quasi che gli uni permettano
di raggiungere la santità e gli altri unicamente la salvezza. Gli esempi, forniti
dal Nuovo Testamento, permettono di verificare queste conclusioni con alcune pagine
assai significative.

description: We analyze optical EPR experimental data performed by Weihs et al in Innsbruck 1997-1998. We show that for some linear combinations of the raw coincidence rates, the experimental results display some anomalous behavior that a more general source state (like non-maximally entangled state) cannot straightforwardly account for. We attempt to explain these anomalies by taking account of the relative efficiencies of the four channels. For this purpose, we use the fair sampling assumption, and assume explicitly that the detection efficiencies for the pairs of entangled photons can be written as a product of the two corresponding detection efficiencies for the single photons. We show that this explicit use of fair sampling cannot be maintained to be a reasonable assumption as it leads to an apparent violation of the no-signalling principle.

description: Given the wide range of applications of time-domain spectroscopy, and particularly THz time-domain spectroscopy, the modelling of a probe pulse propagating through a multilayered structure is often required. Due to the fact that the multilayers are usually grown on a substrate much thicker than the other layers, the transmission of a probe pulse includes a series of echo pulses caused by the multiple reflections at the substrate interfaces. Experiments often measure the time profile and construct the transmitted spectrum only from the first transmitted pulse. Due to the fact that typical substrates lead to times of crossing comparable to the spectral bandwidth, the first transmitted pulse's spectrum and the full transmitted spectrum can be importantly different. It is therefore important to theoretically model the transmission without the echo, to be able to directly compare with experimental results. Here we propose a method to elegantly and easily theoretically remove the echo from the transmission spectrum, without Fourier transforming the signal twice. The spectrum of the transmitted pulse without echo will be produced analytically without additional numerical steps, reducing computational time and program complexity when dealing with larger scale computing.

description: No abstracts are to be cited without prior reference to the author. The integration of marine spatial planning with land planning is often a stated aim of marine plans and policies. The protection of marine ecosystems from externalities generated on land has been a main driver behind marine conservation. Increasing drive to exploit marine resources creates a potential flow of externalities in the opposite direction, from sea to land. For example, marine energy developments require extensive terrestrial infrastructure. Land planning is supported by decades of experience and centuries of trading in property rights supported by accurate boundaries. In contrast, the very idea of being able to plan marine space is recent. Marine spatial and resource rights are held in common. The historical perspective is of marine space incapable of being tamed and the antithesis of modern developable land space. This paper examines the derivation and emerging practice of spatial planning in both regimes. Activities and externalities which cross the land sea divide are identified; terrestrial and marine planning systems are reviewed and differences explained; the drivers for integration are explored and the tools for integration considered.

description: We report a multi-wavelength analysis of the prompt emission and early afterglow of GRB051111 and discuss its properties in the context of current fireball models. The detection of GRB051111 by the Burst Alert Telescope on-board Swift triggered early BVRi' observations with the 2-m robotic Faulkes Telescope North in Hawaii, as well as X-ray observations with the Swift X-Ray Telescope. The prompt gamma-ray emission shows a classical FRED profile. The optical afterglow light curves are fitted with a broken power law, with alpha_1=0.35 to alpha_2=1.35 and a break time around 12 minutes after the GRB. Although contemporaneous X-ray observations were not taken, a power law connection between the gamma-ray tail of the FRED temporal profile and the late XRT flux decay is feasible. Alternatively, if the X-ray afterglow tracks the optical decay, this would represent one of the first GRBs for which the canonical steep-shallow-normal decay typical of early X-ray afterglows has been monitored optically. We present a detailed analysis of the intrinsic extinction, elemental abundances and spectral energy distribution. From the absorption measured in the low X-ray band we find possible evidence for an overabundance of some alpha elements such as oxygen, [O/Zn]=0.7+/-0.3, or, alternatively, for a significant presence of molecular gas. The IR-to-X-ray Spectral Energy Distribution measured at 80 minutes after the burst is consistent with the cooling break lying between the optical and X-ray bands. Extensive modelling of the intrinsic extinction suggests dust with big grains or grey extinction profiles. The early optical break is due either to an energy injection episode or, less probably, to a stratified wind environment for the circumburst medium.

description: Noisy, intermediate-scale quantum (NISQ) computing devices have become an industrial reality in the last few years, and cloud-based interfaces to these devices are enabling exploration of near-term quantum computing on a range of problems. As NISQ devices are too noisy for many of the algorithms with a known quantum advantage, discovering impactful applications for near-term devices is the subject of intense research interest. We explore quantum-assisted machine learning (QAML) on NISQ devices through the perspective of tensor networks (TNs), which offer a robust platform for designing resource-efficient and expressive machine learning models to be dispatched on quantum devices. In particular, we lay out a framework for designing and optimizing TN-based QAML models using classical techniques, and then compiling these models to be run on quantum hardware, with demonstrations for generative matrix product state (MPS) models. We put forth a generalized canonical form for MPS models that aids in compilation to quantum devices, and demonstrate greedy heuristics for compiling with a given topology and gate set that outperforms known generic methods in terms of the number of entangling gates, e.g., CNOTs, in some cases by an order of magnitude. We present an exactly solvable benchmark problem for assessing the performance of MPS QAML models, and also present an application for the canonical MNIST handwritten digit dataset. The impacts of hardware topology and day-to-day experimental noise fluctuations on model performance are explored by analyzing both raw experimental counts and statistical divergences of inferred distributions. We also present parametric studies of depolarization and readout noise impacts on model performance using hardware simulators.

description: We develop a scheme to construct the Hamiltonians of the lambda, vee and cascade type of three-level configurations using the generators of SU(3) group. It turns out that this approach provides a well defined selection rule to give different Hamitonians for each configurations. The lambda and vee type configurations are exactly solved with different initial conditions while taking the two-mode classical and quantized fields . For the classical field, it is shown that the Rabi oscillation of the lambda model is similar to that of the vee model and the dynamics of the vee model can be recovered from lambda model and vice versa simply by inversion. We then proceed to solve the quantized version of both models introducing a novel Euler matrix formalism. It is shown that this dynamical symmetry exhibited in the Rabi oscillation of two configurations for the semiclassical models is completely destroyed on quantization of the field modes. The symmetry can be restored within the quantized models when the field modes are both in the coherent states with large average photon number which is depicted through the collapse and revival of the Rabi oscillations.

description: The nature of current sheet formation in the vicinity of three-dimensional (3D) magnetic null points is investigated. The particular focus is upon the effect of the compressibility of the plasma on the qualitative and quantitative properties of the current sheet. An initially potential 3D null is subjected to shearing perturbations, as in a previous paper [Pontin et al., Phys. Plasmas, in press (2007)]. It is found that as the incompressible limit is approached, the collapse of the null point is suppressed, and an approximately planar current sheet aligned to the fan plane is present instead. This is the case regardless of whether the spine or fan of the null is sheared. Both the peak current and peak reconnection rate are reduced. The results have a bearing on previous analytical solutions for steady-state reconnection in incompressible plasmas, implying that fan current sheet solutions are dynamically accessible, while spine current sheet solutions are not.

description: We analyze the evolution of superfluidity for nonzero orbital angular momentum channels from the Bardeen-Cooper-Schrieffer (BCS) to the Bose-Einstein condensation (BEC) limit in three dimensions. First, we analyze the low energy scattering properties of finite range interactions for all possible angular momentum channels. Second, we discuss ground state ($T = 0$) superfluid properties including the order parameter, chemical potential, quasiparticle excitation spectrum, momentum distribution, atomic compressibility, ground state energy and low energy collective excitations. We show that a quantum phase transition occurs for nonzero angular momentum pairing, unlike the s-wave case where the BCS to BEC evolution is just a crossover. Third, we present a gaussian fluctuation theory near the critical temperature ($T = T_{\rm c}$), and we analyze the number of bound, scattering and unbound fermions as well as the chemical potential. Finally, we derive the time-dependent Ginzburg-Landau functional near $T_{\rm c}$, and compare the Ginzburg-Landau coherence length with the zero temperature average Cooper pair size.

description: No abstracts are to be cited without prior reference to the author. This study provides an empirical review of the attributes of 16 existing marine spatial plans. Almost all plans have a government mandate and the authority to implement spatial planning vested in existing institutions. Decision‐support tools were applied inconsistently across plans and were seldom used dynamically over time. Most spatial planning processes did not select preferred use scenarios; in half the cases there are no metrics of success. Existing marine spatial plans are heterogeneous—there are essential ingredients, but no single recipe for success. More recent plans were developed more quickly and contain more desirable attributes than earlier plans – an indicator of process evolution.

description: Στην παρούσα διπλωματική εργασία, που είναι μέρος ενός ευρύτερου ευρωπαϊκού ερευνητικού προγράμματος που ονομάζεται SEAWIND, μελετήθηκαν τα επίπεδα, οι πηγές και η χωρική και χρονική μεταβλητότητα της έκθεσης στα RF ηλεκτρομαγνητικά πεδία για μια ομάδα μετρήσεων που πραγματοποιήθηκαν στην πόλη της Θεσσαλονίκης, με δύο εκθεσιόμετρα (PEMs), το EME Spy 121 και το EME Spy 140 καθώς επίσης και με τον μετρητή ακτινοβολίας SRM – 3000 της NARDA. Πραγματοποιήθηκε σύγκριση της έκθεσης σε RF ηλεκτρομαγνητικά πεδία που μετρήθηκε με τα εκθεσιόμετρα σε διάφορες αστικές και ημιαστικές περιοχές διάφορων ευρωπαϊκών χωρών. Επίσης μελετήθηκε η συσχέτιση των αποτελεσμάτων μέτρησης μεταξύ των εκθεσιομέτρων και του μετρητή ακτινοβολίας SRM – 3000.
description: In the present thesis, which is part of a wider European project known as SEAWIND we studied the levels, the sources and the spatial and temporal variability of exposure to RF electromagnetic fields for a group of measurements that was realized in the city of Thessaloniki, using two personal exposure meters (PEMs), namely EME Spy 121 and EME Spy 140, as well as a selective radiation meter (SRM-3000 of NARDA).A comparison was achieved with RF electromagnetic field exposure that was measured using PEMs in different urban and sub-urban areas of several European countries. We also studied the correlation of results of measurements between PEMs and the selective radiation meter.

description: The temperature dependence of the superfluid density $ρ_s(T)$ has been measured for a series of ultrathin MBE-grown DyBa$_2$Cu$_3$O$_{7-δ}$ superconducting (SC) films by sub-mm wave interferometry combined with time-domain THz spectroscopy and IR ellipsometry. We find that all films 10 u.c. and thicker show the same universal temperature dependence of $ρ_s(T)$, which follows the critical behavior characteristic of single crystal YBa$_2$Cu$_3$O$_{7-δ}$ as $T$ approaches $T_c$. In 7 u.c. thick films, $ρ_s(T)$ declines steeply upon approaching $T_c$, as expected for the Berezinskii-Kosterlitz-Thouless vortex unbinding transition. Our analysis provides evidence for a sharply defined 4 u.c. non-SC interfacial layer, leaving a quasi-2D SC layer on top. We propose that the SC state in this interfacial layer is suppressed by competing (possibly charge) order.

title: Quantitative incorporation of fishers’ spatial access priorities into strategic conservation planning and fisheries management

Subjects: Pressures, impacts, conservation, and management

description: No abstracts are to be cited without prior reference to the author. Both marine conservation and fisheries management are increasingly incorporating spatial tools such as marine protected areas (MPAs) and seasonal closures. To be able to develop spatial management plans that minimise negative impacts on the fishing community, whilst still fulfilling conservation needs, planners need quantitative data on which parts of the sea are most important to fishers. However, these sorts of data are often lacking or incomplete. Here we show how these data can be obtained through spatial access priority mapping (SAPM), a novel method of participatory mapping that can be used to produce quantitative data for any fishery (Yates & Schoeman, 2013). Unlike the use of remote-sensing data, SAPM actively engages fishers, documenting rather than inferring their priorities. The resultant maps provide a clear visual indication of which areas are most important to fishers and where spatial restrictions might cause greatest conflict. We also show how the quantitative data generated by SAPM can be incorporated into planning software, which allows planners to analyse the relative impact of different management options on the fishing industry and facilitates more holistic conservation planning. This research demonstrates how fishers’ spatial priorities can be incorporated into management in a transparent, quantitative way using SAPM.

description: We present a open source dockerized metagenome analysis application making use of BioContainers where available. The application can be run in a web environment as well as locally in a Windows, Apple or Linux environment. It handles long and short read data and has been tested on PacBio and Illumina whole metagenome sequence reads.

As a case study we performed a whole genome metagenomics study on 54 individuals before and after a trip through the city by public transport. The extracted DNA from palm swabs was whole genome sequenced with Illumina paired-end protocol. Raw data were processed and analyzed with the here presented application.

Results indicate a shift towards higher microbiome diversity in the after samples, but also show an enrichment of certain non-skin-related species in the before samples (after hand washing), which decreases in abundance over time. Although variability between individuals was high, several significant species in the before samples correlated with warm water, most likely representing a residue from hand washing. Categories enriched in the after samples were mainly food associated microbes. In terms of metabolic category, The highest abundant category in both sets was, not surprisingly, species of the skin microbiome.

description: As Einstein's equations for binary compact object inspiral have only been approximately or intermittently solved by analytic or numerical methods, the models used to infer parameters of gravitational wave (GW) sources are subject to waveform modeling uncertainty. Using a simple scenario, we illustrate these differences, then introduce a very efficient technique to marginalize over waveform uncertainties, relative to a pre-specified sequence of waveform models. Being based on RIFT, a very efficient parameter inference engine, our technique can directly account for any available models, including very accurate but computationally costly waveforms. Our evidence and likelihood-based method works robustly on a point-by-point basis, enabling accurate marginalization for models with strongly disjoint posteriors while simultaneously increasing the reusability and efficiency of our intermediate calculations.

description: No abstracts are to be cited without prior reference to the author. The concept of multifunctional use of marine offshore areas receives increased significance in the light of sustainable development in heavily used marine areas. Here we defined potential areas in the German EEZ for the co-utilization of offshore wind farms and offshore aquaculture applying integrated multi-trophic aquaculture (IMTA) approaches. We combined a geographic information system (GIS), spatial distribution models and multi-criteria evaluation (MCE) to index suitable multifunctional sites. The procedure as well as the main findings of the GIS-MCE modelling approach are summarised to demonstrate the applicability of the GIS-MCE and the need for modelling techniques for spatial optimisation using geo-spatial tools. Finally, different spatial multi-use scenarios for the coupling of offshore IMTA-systems and wind farms are evaluated in order to support efficient and sustainable marine spatial management (MSP) strategies.

description: The prevalence of location-based social networks (LBSNs) has eased the understanding of human mobility patterns. Knowledge of human dynamics can aid in various ways like urban planning, managing traffic congestion, personalized recommendation etc. These dynamics are influenced by factors like social impact, periodicity in mobility, spatial proximity, influence among users and semantic categories etc., which makes location modelling a critical task. However, categories which act as semantic characterization of the location, might be missing for some check-ins and can adversely affect modelling the mobility dynamics of users. At the same time, mobility patterns provide a cue on the missing semantic category. In this paper, we simultaneously address the problem of semantic annotation of locations and location adoption dynamics of users. We propose our model HAP-SAP, a latent spatio-temporal multivariate Hawkes process, which considers latent semantic category influences, and temporal and spatial mobility patterns of users. The model parameters and latent semantic categories are inferred using expectation-maximization algorithm, which uses Gibbs sampling to obtain posterior distribution over latent semantic categories. The inferred semantic categories can supplement our model on predicting the next check-in events by users. Our experiments on real datasets demonstrate the effectiveness of the proposed model for the semantic annotation and location adoption modelling tasks.
