description: Ostfriesland erstreckt sich über die Landkreise Aurich, Leer und Wittmund sowie die Stadt Emden. Es liegt im Nordwesten Niedersachsens unmittelbar an der Nordsee und benachbart zu den Niederlanden. Aufgrund des hohen Grundwasserstandes ist die Holzerhaltung in archäologischen Befunden sehr umfangreich und gut. Die erhaltenen Hölzer, sowohl in primärer als auch in sekundärer Nutzung, sind zumeist als Schling in den Brunnen verbaut. Gefäße finden sich hingegen in den Brunnenschächten. Vor allem aus Befunden der Römischen Kaiserzeit und des Mittelalters liegen zahlreiche bearbeitete Hölzer und Holzgegenstände vor. Unter den Objekten ragen vor allem Gefäße (gedrechselte Schalen, Dosen, Pokale, Eimer und Mollen), Möbelteile, Ackergeräte (Pflugscharen, Eggen), Teile von Wagen (Achsen, Räder) sowie Schiffsspanten heraus. Hinzu kommt eine große Zahl bisher noch nicht eindeutig angesprochener Objekte, die in primärer Nutzung dem Hausbau und technischen Anlagen zugeordnet werden können oder noch gänzlich unidentifiziert sind.

ECSI Business Model Analysis & Typology (Deliverable 6.6)
Creators: name: Bischof, Alice
Publisher: name: Zenodo
Year: 2021

description: How can the business models of Edible City Solution Initiatives (ECSI) be understood to support their continuity and upscaling? This is the guiding question the present Deliverable (D6.6) seeks to answer through the analysis and typology of ECSI business models, including
 the derivation of strategies for continuity and growth per type. D6.6 is informed by previous work done in D6.5 on the Triple Layered Business Model Canvas (TLBMC). It is part of the action plan of the EdiCitNet Business Consulting Team (D6.4). It connects questions of ECSI scaling and growth raised in D3.3 (forthcoming) with a new analytical tool for ECSI business model analysis. We found that commercial value creation and capture does not play a major role for many ECSI within EdiCitNet, and that the TLBMC (cf. D6.5) does not offer a useful tool for ECSI business model analysis precisely because it implies commercialisation as primary way of value creation and capture. Yet, like any type of organisation, all ECSI follow a basic mechanism of value creation and capture. The present Deliverable builds on that basic mechanism and develops the Organisational Value System (OVS) to be able to analyse the variety of value creation and capture mechanisms that ECSI follow – including, but not restricted to, commercialisation (cf. D6.3 and D6.4). OVS-based analyses and a typology of various ECSI are presented, including strategies for continuity and growth per type. Three archetypes are distinguished: • Commercial Type
 • Social Type
 • Nature-Based Type Further, four mixed types are distinguished: • Commercial-Social Type
 • Social-Nature-based Type
 • Nature-based-Commercial Type
 • Social-Commercial-Nature-based Type. For each type, a business model analysis with a case example and strategies for continuity and growth are presented. The proposed typology, strategies for continuity and growth, and the potential applications of the OVS are discussed. The report concludes with ten lessons learnt from the interplay of science and practice that brought the OVS into being.

description: Gravitational lensing is one of the most impressive celestial phenomena, which has interesting behaviors in its strong field limit. Near such limit, Bozza finds that the deflection angle of light is well-approximated by a logarithmic term and a constant term. In this way he explicitly derived the analytic expressions of deflection angles for a few types of black holes. In this paper, we study the explicit calculation to two new types of metrics in the strong field limit: (i) the Schwarzschild metric extended with an additional $r^{-n}(n\geq 3)$ term in the metric function; (ii) the Reissner-Nordstrom metric extended with an additional $r^{-6}$ term in the metric function. With such types of metrics, Bozza's original way of choosing integration variables may lead to technical difficulties in explicitly expressing the deflection angles, and we use a slightly modified version of Bozza's method to circumvent the problem.

description: Josephson junctions containing ferromagnetic materials are generating interest for use in superconducting electronics and cryogenic memory. Optimizing the performance of such junctions is an ongoing effort, requiring exploration of a broad range of magnetic systems. Here we study supercurrent transmission through Ni/Ru/Ni synthetic antiferromagnets, with the idea that their magnetic properties may be superior to those of isolated Ni layers. We find that the decay of the supercurrent as a function of Ni thickness is very slow, with a decay length of 7.5 $\pm$ 0.8 nm. We also characterize the magnetic properties of the synthetic antiferromagnets as a function of Ni and Ru thicknesses.

description: We propose an alternative derivation for the dynamic admittance of a gated quantum dot connected by a single-channel lead to an electron reservoir. Our derivation, which reproduces the result of Prêtre, Thomas, and Büttiker for the universal charge-relaxation resistance, shows that at low frequencies, the current leaving the dot lags after the entering one by the Wigner-Smith delay time. We compute the capacitance when interactions are taken into account only on the dot within the Hartree-Fock approximation and study the Coulomb-blockade oscillations as a function of the Fermi energy in the reservoir. In particular we find that those oscillations disappear when the dot is fully `open', thus we reconcile apparently conflicting previous results.

description: The Large Area Telescope (LAT) on board the \Fermi Gamma-ray Space Telescope (\Fermi) shows long-lasting high-energy emission in many gamma-ray bursts (GRBs), similar to X-ray afterglows observed by the Neil Gehrels Swift Observatory \citep[\textit{Swift};][]{gehrels2004}. Some LAT light curves (LCs) show a late-time flattening reminiscent of X-ray plateaus. We explore the presence of plateaus in LAT temporally extended emission analyzing GRBs from the second \lat GRB Catalog \citep[2FLGC;][]{Ajello2019apj} from 2008 to May 2016 with known redshifts, and check whether they follow closure relations corresponding to 4 distinct astrophysical environments predicted by the external forward shock (ES) model. We find that three LCs can be fit by the same phenomenological model used to fit X-ray plateaus \citep{Willingale2007} and show tentative evidence for the existence of plateaus in their high-energy extended emission. The most favorable scenario is a slow cooling regime, whereas the preferred density profile for each GRBs varies from a constant density ISM to a $r^{-2}$ wind environment. We also compare the end time of the plateaus in $γ$-rays and X-rays using a statistical comparison with 222 \textit{Swift} GRBs with plateaus and known redshifts from January 2005 to August 2019. Within this comparison, the case of GRB 090510 shows an indication of chromaticity at the end time of the plateau. Finally, we update the 3-D fundamental plane relation among the rest frame end time of the plateau, its correspondent luminosity, and the peak prompt luminosity for 222 GRBs observed by \textit{Swift}. We find that these three LAT GRBs follow this relation.

The situational suitability of job evaluation plans in unionized environments
Creators: name: Stobart, Anne Patricia
Publisher: name: University of British Columbia
Year: 2010

description: Despite the age of and scholarly interest in job evaluation, little research has been done which would assist the practitioner in determining what plan would best suit any given situation (particularily within a unionized context) and what criteria can be used to measure plan effectiveness. The focus of this study was to identify and analyze the situational factors which influence a firm's choice of job evaluation plans, and ascertain the impact these factors may have on plan effectiveness, as well as, to develop common criteria for measuring effectiveness. A sample of three British Columbia unionized organizations was examined, and the observations arising from each plan were documented in the form of a case study. Each plan reflected historical, environmental and internal influences peculiar to the individual organization while, at the same, all had been subjected to certain common exigencies. The observations of the sample supported earlier research on the influence of various factors. For example, as noted in the literature, senior management support, the existence of an appeal mechanism and regular plan audit, as well as, full information accessibility appeared to correlate with plan effectiveness. Additionally, it was noted that the stability and competency of the analysts, as well as, the nature of the work environment were particularily influential. A growth in union interest in job evaluation was evident and the relationship between management and the union strongly dictated the degree of freedom with which management was able to apply job evaluation. However, job evaluation was perceived, by both management and labour, to be non-adversarial in nature. The traditional job evaluation process was evidently time-consuming and cumbersome; all organizations expressed a need for a more expedient process. Only one organization expressed concern regarding the issue of equal pay for work of equal value, suggesting that it is, currently, more of a philosophical than practical issue vis a vis job evaluation. Few common criteria of job evaluation plan effectiveness were applied. Nevertheless, based on common concerns and experiences observed in the study a measurement "checklist" was compiled which outlined the following job evaluation plan requirements: (1) predetermined goals of the plan, (2) senior management support, (3) workable terms of reference, (4) evaluation method suitability, (5) evaluation method soundness, (6) evaluation consistency, (7) checks for accuracy/objectivity, (8) plan credibility and comprehensibility, (9) administrative efficiency, and (10) wage/classification structure rationality. Insofar as labour and management share a common goal for job evaluation, the potential for increased sophistication and effectiveness of plan development and administration appears to be great.

description: We present high quality (high signal-to-noise ratio and moderate spectral resolution) near-infrared (near-IR) spectroscopic observations of 23 well-known broad-emission line active galactic nuclei (AGN). Additionally, we obtained simultaneous (within two months) optical spectroscopy of similar quality. The near-IR broad emission line spectrum of AGN is dominated by permitted transitions of hydrogen, helium, oxygen, and calcium, and by the rich spectrum of singly-ionized iron. In this paper we present the spectra, line identifications and measurements, and address briefly some of the important issues regarding the physics of AGN broad emission line regions. In particular, we investigate the excitation mechanism of neutral oxygen and confront for the first time theoretical predictions of the near-IR iron emission spectrum with observations.

description: This work reports the general design and characterization of two exotic, anomalous nonequilibrium topological phases. In equilibrium systems, the Weyl nodes or the crossing points of nodal lines may become the transition points between higher-order and first-order topological phases defined on two-dimensional slices, thus featuring both hinge Fermi arc and surface Fermi arc. We advance this concept by presenting a strategy to obtain, using time-sequenced normal insulator phases only, Floquet higher-order Weyl semimetals and Floquet higher-order nexus semimetals, where the concerned topological singularities in the three-dimensional Brillouin zone border anomalous two-dimensional higher-order Floquet phases. The fascinating topological phases we obtain are previously unknown and can be experimentally studied using, for example, a three-dimensional lattice of coupled ring resonators.

D5.3 Final LCA report of the MegaRoller device
Creators: name: Apolonia, Maria
Publisher: name: Zenodo
Year: 2020
Subjects: MegaRoller

description: So far, very few studies have focused on the quantification of the environmental impacts of a wave energy converter. The current study presents a Life Cycle Assessment (LCA) study of the MegaRoller wave energy converter, aiming to contribute to decision making regarding the least carbon and energy intensive design choices. The LCA encompasses all life cycle stages from “cradle-to-grave” for the wave energy converter, including the panel, foundation, PTO and mooring system, considering its deployment in Peniche, Portugal. Background data was mainly sourced from the manufacturer whereas foreground data was sourced from the Ecoinvent database (v.3.4) and ReCiPe and CED impact assessment methods were applied. The LCA application to the MegaRoller device resulted in a global warming potential (GWP) of 33.8 gCO2 eq/kWh and Cumulative Energy Demand (CED) of 432 kJ/kWh. This LCA is aligned with all previous studies on MRE technologies in concluding the main environmental impacts are due to materials use and manufacture, while Assembly & Installation and O&M do not show significant impacts. The impact of manufacture is mainly due to high amounts of material used, particularly steel. Energy and carbon payback periods were both estimated to be around 28 months. End-of-Life stage is currently excluded from operational boundaries of the majority of MRE developments and its inclusion in eco-design initiatives is challenged by uncertainties on a temporal, technological and business level such as uncertainties regarding recycling ratios. This report corroborated with previous studies by proving the importance of the End-of-Life scenario to the overall environmental performance and highlighted the need for further efforts to better understand how to model this stage. The scenario analysis showed that there are alternative process and design choices that may improve the energy consumption and GHG emissions throughout the life cycle. While some scenarios showed a modest influence, others such as varying recycling rates and alternative material for stainless steel resulted in significant variations in the overall results. The resulting GHG emissions and energy consumptions are generally comparable with earlier studies for wave and tidal technologies and are very low when compared other power generating technologies. Opportunities to reduce the environmental impacts in the final design of the MegaRoller wave energy converter could potentially lie in reducing the quantity of steel by studying alternatives for its replacement. This study confirms the effectiveness of LCA as a tool for assessing environmental impacts of marine renewable energy sources and comparing results with alternative energy sources and informing decisions for concept and product development

description: The modification of the wetting properties of marble surfaces upon multi-scale texturing induced by ultrafast laser processing (340 fs pulse duration, 1030 nm wavelength) has been investigated with the aim of evaluating its potential for surface protection. The contact angle (CA) of a water drop placed on the surface was used to assess the wettability of the processed areas. Although the surfaces are initially hydrophilic upon laser treatment, after a few days they develop a strong hydrophobic behavior. Marble surfaces have been irradiated with different scan line separations to elucidate the relative roles of multi-scale roughness (nano- and micro-texture) and chemical changes at the surface. The time evolution of the contact angle has been then monitored up to 11 months after treatment. A short and a long-term evolution, associated to the combined effect of multi-scale roughness and the attachment of chemical species at the surface over the time, have been observed. XPS and ATR measurements are consistent with the progressive hydroxylation of the laser treated surfaces although the additional contribution of hydrocarbon adsorbates to the wettability evolution cannot be ruled-out. The robustness of the results has been tested by CA measurements after cleaning in different conditions with very positive results.

description: To improve the Information Technology (I.T.) graduate skill set, students need to be immersed in as realistic a software development environment as possible. In continuing our work on integrating Agile Methodology into the Capstone Program of our Bachelor of Science in I.T. (BSIT) degree program, this paper discusses the student challenges and difficulties during the software development project, and provides recommendations on improving the student overall learning process in such a program. We collected survey data from the whole population of 90 BSITstudents across four academic years about their experience with their client and the Capstone Program itself. Conceptual content analysis was then applied to discover and describe underlying themes. Also, faculty advisers were tasked with writing about their interactions, thoughts, and observations on their respective student group advisees. These showed issues with time management, communication, and competency. Also, groups that excelled exhibited better team coordination and a complete grasp of the Agile methodology. For future implementations, clearer task definition and reducing the skill gaps are necessary for better execution.

Assuming that the Hamiltonian is rotationally invariant and parity conserving we identify all such systems which allow additional (pseudo)tensor integrals of motion that are second order matrix polynomials in the momenta. Previously we found all the (pseudo)scalar and (axial)vector integrals of motion. No non-obvious tensor integrals exist. However, nontrivial pseudo-tensor integrals do exist. Together with our earlier results we give a complete list of such superintegrable Hamiltonian systems allowing second-order integrals of motion.

description: We consider a single Rouse polymer chain in two dimensions in presence of a transverse shear flow along the $x$ direction and calculate the persistence probability $P_0(t)$ that the $x$ coordinate of a bead in the bulk of the chain does not return to its initial position up to time $t$. We show that the persistence decays at late times as a power law, $P_0(t)\sim t^{-θ}$ with a nontrivial exponent $θ$. The analytical estimate of $θ=0.359...$ obtained using an independent interval approximation is in excellent agreement with the numerical value $θ\approx 0.360\pm 0.001$.

description: The mission statement(s) (MS) is one of the most-used tools for planning and management. Universities worldwide have implemented MS in their knowledge planning and management processes since the 1980s. Research studies have extensively explored the content and readability of MS and its effect on performance in firms, but their effect on public or nonprofit institutions such as universities has not been scrutinized with the same intensity. This study used Gunning's Fog Index score to determine the readability of a sample of worldwide universities' MS and two rankings, i.e., Quacquarelli Symonds World University Ranking and SCImago Institutions Rankings, to determine their effect on performance. No significant readability differences were identified in regions, size, focus, research type, age band, or status. Logistic regression (cumulative link model) results showed that variables, such as universities' age, focus, and size, have more-significant explanatory power on performance than MS readability.

description: The real part of the in-plane optical self-energy data in underdoped Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+δ}$ (Bi-2212) and ortho II YBa$_{2}$Cu$_{3}$O$_{6.5}$ contains new and important information on the pseudogap. Using a theoretical model approach we find that the density of state lost below the pseudogap $Δ_{pg}$ is accompanied with a pileup just above this energy. The pileup along with a sharp mode in the bosonic spectral function leads to an unusually rapid increase in the optical scattering rate and a characteristically sloped peak in the real part of the optical self-energy. These features are not found in optimally doped and overdoped samples and represent a clearest signature so far of the opening of a pseudogap in the in-plane optical conductivity.

description: Fast and effective responses are required when a natural disaster (e.g., earthquake, hurricane, etc.) strikes. Building damage assessment from satellite imagery is critical before relief effort is deployed. With a pair of pre- and post-disaster satellite images, building damage assessment aims at predicting the extent of damage to buildings. With the powerful ability of feature representation, deep neural networks have been successfully applied to building damage assessment. Most existing works simply concatenate pre- and post-disaster images as input of a deep neural network without considering their correlations. In this paper, we propose a novel two-stage convolutional neural network for Building Damage Assessment, called BDANet. In the first stage, a U-Net is used to extract the locations of buildings. Then the network weights from the first stage are shared in the second stage for building damage assessment. In the second stage, a two-branch multi-scale U-Net is employed as backbone, where pre- and post-disaster images are fed into the network separately. A cross-directional attention module is proposed to explore the correlations between pre- and post-disaster images. Moreover, CutMix data augmentation is exploited to tackle the challenge of difficult classes. The proposed method achieves state-of-the-art performance on a large-scale dataset -- xBD. The code is available at https://github.com/ShaneShen/BDANet-Building-Damage-Assessment.

description: We consider an Ornstein-Uhlenbeck process with values in R^n driven by a Lévy process (Z_t) taking values in R^d with d possibly smaller than n. The Lévy noise can have a degenerate or even vanishing Gaussian component. Under a controllability condition and an assumption on the Lévy measure of (Z_t), we prove that the law of the Ornstein-Uhlenbeck process at any time t>0 has a density on R^n. Moreover, when the Lévy process is of $α$-stable type, $α\in (0,2)$, we show that such density is a $C^{\infty}$-function.

description: We study experimentally the paths of an assembly of cracks growing in interaction in a heterogeneous two-dimensional elastic brittle material submitted to uniaxial stress. For a given initial crack assembly geometry, we observe two types of crack path. The first one corresponds to a repulsion followed by an attraction on one end of the crack and a tip to tip attraction on the other end. The second one corresponds to a pure attraction. Only one of the crack path type is observed in a given sample. Thus, selection between the two types appears as a statistical collective process.

description: The interaction between a central qubit spin and a surrounding bath of spins is critical to spin-based solid state quantum sensing and quantum information processing. Spin-bath interactions are typically strongly anisotropic, and rapid physical rotation has long been used in solid-state nuclear magnetic resonance to simulate motional averaging of anisotropic interactions, such as dipolar coupling between nuclear spins. Here, we show that the interaction between electron spins of nitrogen-vacancy centers and a bath of $^{13}$C nuclear spins in a diamond rotated at up to 300,000rpm introduces decoherence into the system via frequency-modulation of the nuclear spin Larmor precession. The presence of an off-axis magnetic field necessary for averaging of the dipolar coupling leads to a rotational dependence of the electron-nuclear hyperfine interaction, which cannot be averaged out with experimentally achievable rotation speeds. Our findings offer new insights into the use of physical rotation for quantum control with implications for quantum systems having motional and rotational degrees of freedom that are not fixed.

description: The novel MegaRoller technology represents state-of-the-art solution for unlocking the potential in wave energy. The European Union’s Horizon 2020 research and innovation programme funded MegaRoller project has been an effort to develop the power take-off component for a 1 MW oscillating wave surge wave energy converter and consequently decrease the levelized costs of electricity for the technology type. The project has spearheaded development of wave energy conversion technologies and sought to facilitate the uptake of wave energy as an alternative technology in the production of renewable energy. Several innovations in the design of hardware and software components of the PTO have been achieved resulting in a notable decrease in the levelized costs of electricity for the technology type. The achieved range of levelized costs of energy for the MegaRoller technology is 148-100 EUR/MWh. Further costs reductions are expected to be realized through increased deployments of the technology and to follow a costs reduction trajectory similar to other variable renewable energy technologies. Following 50 MW of cumulative deployment LCOE is forecast to reach 116-60 EUR/MWh and in the most conservative assessment decline below 100 EUR/MWh after 130 MW deployed capacity. Assuming an average 20 % learning rate throughout development, the cost of the MegaRoller technology will reach parity with the current lowest cost solar PV and onshore wind projects at 23 EUR/MWh. The ability of the MegaRoller technology to supplement other renewable energy technologies in the electricity mix and to extract a higher value per produced kilowatt hour has also been modelled. As wave power is not correlated with the day-night-cycle of solar radiation nor the local wind climate determining wind power production, wave energy can support a power grid with increased solar and wind production capacity and proportionately deployed claim a higher price per kWh produced. The development of the PTO technology for OWSC technologies carried out through the MegaRoller project and the achieved results are highly encouraging for further decrease of costs and uptake of wave energy

description: Yehuda Vardi introduced the term network tomography and was the first to propose and study how statistical inverse methods could be adapted to attack important network problems (Vardi, 1996). More recently, in one of his final papers, Vardi proposed notions of metrics on networks to define and measure distances between a network's links, its paths, and also between different networks (Vardi, 2004). In this paper, we apply Vardi's general approach for network metrics to a real data network by using data obtained from special data network tools and testing procedures presented here. We illustrate how the metrics help explicate interesting features of the traffic characteristics on the network. We also adapt the metrics in order to condition on traffic passing through a portion of the network, such as a router or pair of routers, and show further how this approach helps to discover and explain interesting network characteristics.

description: Context: In addressing how best to estimate how much effort is required to develop software, a recent study found that using exemplary and recently completed projects [forming Bellwether moving windows (BMW)] in software effort prediction (SEP) models leads to relatively improved accuracy. More studies need to be conducted to determine whether the BMW yields improved accuracy in general, since different sizing and aging parameters of the BMW are known to affect accuracy. Objective: To investigate the existence of exemplary projects (Bellwethers) with defined window size and age parameters, and whether their use in SEP improves prediction accuracy. Method: We empirically investigate the moving window assumption based on the theory that the prediction outcome of a future event depends on the outcomes of prior events. Sampling of Bellwethers was undertaken using three introduced Bellwether methods (SSPM, SysSam, and RandSam). The ergodic Markov chain was used to determine the stationarity of the Bell-wethers. Results: Empirical results show that 1) Bellwethers exist in SEP and 2) the BMW has an approximate size of 50 to 80 exemplary projects that should not be more than 2 years old relative to the new projects to be estimated. Conclusion: The study's results add further weight to the recommended use of Bellwethers for improved prediction accuracy in SEP.

description: We consider few-photon ionization of atomic lithium by linearly polarized femtosecond laser pulses, and demonstrate that asymmetries of the electron angular distribution can occur for initially polarized (2p, m=+1) target atoms. The dependence of the photoelectron emission angle relative to the electric field direction is investigated at different laser intensities and wavelengths. The experimental spectra show excellent agreement with numerical solutions of the time-dependent Schroedinger equation. In the perturbative picture, the angular shift is traced back to interferences between partial waves with mean magnetic quantum number $\ne$0. This observation allows us to obtain quantum mechanical information on the electronic final state.

Collinearity in generalized linear models
Creators: name: Mackinnon, Murray J.
Publisher: name: University of British Columbia
Year: 2010

description: The concept of collinearity for generalized linear models is introduced and compared to that for standard linear models. Two approaches for detecting collinearity are presented and shown to lead to the same diagnostic procedure. These are analysed for the Poisson, gamma, inverse Gaussian, pth order, binomial proportion and negative binomial models. A bound is derived for the degree of collinearity in a generalized linear model in terms of that of the standard linear model. Estimation methods based on ridge, prior likelihood and principal components are proposed, and briefly illustrated with a Monte Carlo simulation of a gamma model.
