description: A scheme for a THz frequency standard based on three-photon coherent population trapping in stored ions is proposed. Assuming the propagation directions of the three lasers obey the phase matching condition, we show that stability of few 10$^{-14}$ at one second can be reached with a precision limited by power broadening to $10^{-11}$ in the less favorable case. The referenced THz signal can be propagated over long distances, the useful information being carried by the relative frequency of the three optical photons.

description: SocialRES aims to devise effective ways of increasing social innovation leading to greater social acceptability of renewable energy systems. This is done by a better understanding of support structures for successful social innovations in the renewable energy sector such as Renewable Energy Cooperatives, Aggregators and Crowdfunding Platforms. These businesses facilitate consumers to take an active role in the electricity system. Through research excellence and co-creation of knowledge, SocialRES will develop socially innovative and inclusive strategies for the energy system of the future. SocialRES will supplement the existing fragmented data on social innovations with new understandings from businesses, end-users and stakeholders to provide a comprehensive evidence base for policy design. Innovative techniques will be employed such as a Peer to Peer (P2P) crowd-investing for renewable energy sources projects, P2P lending and P2P virtual photovoltaic electricity platform for aggregators. The innovative P2P photovoltaic virtual platform will be developed as a pilot software application in off-line mode and will facilitate the understanding about existing barriers within current electricity markets and policies. Experience will therefore be accumulated related to the main issues with the common access for energy trades between different actors on the market: prosumers, consumers, balancing responsible party and distributed photovoltaic generators.

description: Neurodevelopment of preterm children has become an outcome of major interest since the improvement in survival due to advances in neonatal care. Many studies focused on the relationships among prenatal characteristics and neurodevelopmental outcome in order to identify the higher risk preterms’ subgroups. The aim of this study is to analyze and put in relation growth and development trajectories to investigate their association.
346 children born at the S.Orsola Hospital in Bologna from 01/01/2005 to 30/06/2011 with a birth weight of <1500 grams were followed up in a longitudinal study at different intervals from 3 to 24 months of corrected age. During follow-up visits, preterms’ main biometrical characteristics were measured and the Griffiths Mental Development Scale was administered to assess neurodevelopment. Latent Curve Models were developed to estimate the trajectories of length and of neurodevelopment, both separately and combined in a single model, and to assess the influence of clinical and socio-economic variables.
Neurodevelopment trajectory was stepwise declining over time and length trajectory showed a steep increase until 12 months and was flat afterwards. Higher initial values of length were correlated with higher initial values of neurodevelopment and predicted a more declining neurodevelopment. SGA preterms and those from families with higher status had a less declining neurodevelopment slope, while being born from a migrant mother proved negative on neurodevelopment through the mediating effect of a being taller at 3 months. A longer stay in NICU used as a proxy of preterms’ morbidity) was predictive of lower initial neurodevelopment levels.
At 24 months, neurodevelopment is more similar among preterms and is more accurately evaluated. The association among preterms’ neurodevelopment and physiological growth may provide further insights on the determinants of preterms’ outcomes. Sound statistical methods, exploiting all the information collected in a longitudinal study, may be more appropriate to the analysis.

description: Recent discovery of high T_c superconductivity in Fe-based compounds may have opened a new pathway to the room temperature superconductivity. The new materials feature FeAs layers instead of the signature CuO_2 planes of much-studied cuprates. A model Hamiltonian describing FeAs layers is introduced, highlighting the crucial role of puckering of As atoms in promoting d-electron itinerancy and warding off large local-moment magnetism of Fe ions, the main enemy of superconductivity. Quantum many-particle effects in charge, spin and multiband channels are explored and a nesting-induced spin density-wave order is found in the parent compund. We argue that this largely itinerant antiferromagnetism and high T_c itself are essentially tied to the multiband nature of the Fermi surface.

description: On-campus activities like positions of responsibility in campus amenities and participation in research, benefit the students as well as the university, while also making students financially self-sufficient to a certain extent. However, this student participation is stymied by lack of awareness and motivation. Significant impetus to innovation and student participation can be provided by incentivization of these activities. In this paper, we propose a system to create a blockchain-based economy, to incentivize students with empirical benefits or monetary awards calculated using objective algorithms. The incentivization algorithms have been designed for three promising use cases: research work, positions of responsibility in universities, and crowdfunding. The demonstrated implementation of this system utilises VJTI Chain, an already established Proof of Authority blockchain in VJTI Mumbai, India. This creates a circular economy within the university which encourages students to earn more rewards by reinforcing positive feedback.

description: These days, the wafering of silicon with the usage of the diamond wire process is well established. The huge experience of wafer manufacturers has enabled many process optimizations over the last decade. But, in detail regarding the wafering costs there are some parameters or process peculiarities that are not optimized yet. This study presents an analysis of a new brick bonding adhesive that is compared to the established two compound resin bonding glue. The new hot melt glue was analyzed regarding the stress state at the bonding interface, the chipping potential at the wafer edges and the wafer strength. The residual stresses at the bonding layer are justified by performing a simplified experiment and FEM simulation to calculate the existing stress state caused by glue curing. The edge chipping was evaluated by the usage of an automatic algorithm that was able to quantify the chipping events at the wafer edges by image analysis. The final wafer strength was determined by mechanical testing and Weibull analysis. In this work, the application of hot melt bonding was tested and the consequences to the wafer properties were analyzed. Our conclusion is that the hot melt bonding shows the potential to substitute the current resin-based glue.

description: How should we understand the social and political effects of the datafication of human life? This paper argues that the effects of data should be understood as a constitutive shift in social and political relations. We explore how datafication, or quantification of human and non-human factors into binary code, affects the identity of individuals and groups. This fundamental shift goes beyond economic and ethical concerns, which has been the focus of other efforts to explore the effects of datafication and AI. We highlight that technologies such as datafication and AI (and previously, the printing press) both disrupted extant power arrangements, leading to decentralization, and triggered a recentralization of power by new actors better adapted to leveraging the new technology. We use the analogy of the printing press to provide a framework for understanding constitutive change. The printing press example gives us more clarity on 1) what can happen when the medium of communication drastically alters how information is communicated and stored; 2) the shift in power from state to private actors; and 3) the tension of simultaneously connecting individuals while driving them towards narrower communities through algorithmic analyses of data.

description: We reexamine whether the essence of high-Tc superconductivity is contained in doped Hubbard models on the square lattice by using recently developed pre-projected Gaussian-basis Monte Carlo method. The superconducting correlations of the dx2-y2 wave symmetry in the ground state at distance r decays essentially as inverse cubic of r. The upper bound of the correlation at long distances estimated by this unbiased method is 0.001, indicating that recent extensions of dynamical mean-field theories and variational methods yielded at least an order of magnitude overestimates of it. The correlations are too weak for the realistic account of the cuprate high-Tc superconductivity.

description: The fundamental interaction between free electrons and light stands at the base of both classical and quantum physics, with applications in free-electron acceleration, radiation sources, and electron microscopy. Yet, to this day, all experiments involving free-electron light interactions are fully explained by describing the light as a classical wave, disregarding its quantum nature. Here, we observe quantum statistics effects of photons on free-electron-light interactions. We demonstrate interactions passing continuously from Poissonian to super-Poissonian and up to thermal statistics, unveiling a surprising manifestation of Bohr's Correspondence Principle: the transition from quantum walk to classical random walk on the free-electron energy ladder. The electron walker serves as the probe in non-destructive quantum detection, measuring the photon-correlation ${g^{(2)} (0)}$ and higher-orders ${g^{(n)} (0)}$. Unlike conventional quantum-optical detectors, the electron can perform both quantum weak measurements and projective measurements by evolving into an entangled joint-state with the photons. Our findings suggest free-electron-based non-destructive quantum tomography of light, and constitute an important step towards combined attosecond-temporal and sub-A-spatial resolution microscopy.
A study of the working alliance in psychotherapy
Creators: name: Adler, Jean Vera
Publisher: name: University of British Columbia

description: Originally identified by Freud (1912, 1913), the therapeutic or working alliance between client and therapist has in the last decade been proposed as the common factor that could account for psychotherapeutic outcome regardless of the theoretical orientations and/or techniques employed by therapists. Psychotherapy researchers (Allen, Newsom, Gabbard, & Coyne, 1984; Hartley & Strupp, 1983; Horvath, 1981; Luborsky, 1976; Marziali, Marmar, & Krupnick, 1981) have developed various scales for measuring the alliance and have quite consistently demonstrated an alliance-outcome relationship. The Working Alliance Inventory (Horvath, 1981, 1982) is the first self-report instrument developed to measure the alliance construct. It is based on the theory proposed by Bordin (1975, 1979) that the alliance is the product of the synergistic combination of three highly related components -- goal mutuality, agreement regarding relevant tasks and responsibilities, and the development of personal bonds or attachments. In the present study, the Working Alliance Inventory was administered after each of the first five, the tenth, and the final sessions of 44 psychotherapy cases. It was found to be statistically significantly related to outcome by the third to fifth session on four of the six outcome measures employed. Another self-report measure, the Helping Alliance Questionnaire (Luborsky, McLellan, Woody, O'Brian, & Auerbach, 1985) was also administered at the third session, as well as measures of therapist empathy, expertness, attractiveness, and trustworthiness. The Helping Alliance Questionnaire, which is based on a clinically-derived definition of the alliance, was found to be statistically significantly related to outcome on all six of the measures employed. Speculations concerning the differential patterns of results with the two alliance measures are offered.

description: PV deployment growth is an unmatched success story in the energy sector over recent years. However, European PV manufacturers are facing a decline in production due to competition from third countries. The fragmentation of the value chain is believed to be one of the major factors for this decrease in the competitiveness. SUPER PV is a collaborative European-funded project initiated in 2018 by 26 partners in reaction to this trend. It pursues a significant LCOE reduction for innovative PV systems based on a hybrid combination of technological innovations and data management solutions along the PV value chain. Responding to the need of evaluating proposed innovations in terms of economic feasibility and market trends, a dedicated task force, an Exploitation Team, was introduced at the beginning of the project as a main instrument for overseeing achievement of KPI’s and beyond, in the ever-changing landscape of the PV sector.

description: Quantum mechanical phase factors can be related to dynamical effects or to the geometrical properties of a trajectory in a given space - either parameter space or Hilbert space. Here, we experimentally investigate a quantum mechanical phase factor that reflects the topology of the SO(3) group: since rotations by $π$ around antiparallel axes are identical, this space is doubly connected. Using pairs of nuclear spins in a maximally entangled state, we subject one of the spins to a cyclic evolution. If the corresponding trajectory in SO(3) can be smoothly deformed to a point, the quantum state at the end of the trajectory is identical to the initial state. For all other trajectories the quantum state changes sign.

PV Driven Energy Management and System Integration

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 1730-1735
description: In Spain, industry is identified as one of the most important sectors regarding energy consumption, especially for medium and large factories. In this regard, a tool was developed for analyzing energy behavior of an industrial monitored process from multiple points of view, being solar photovoltaic analysis one of the most important ones. This module makes use of information introduced by the user, such as electricity bills or location of the factory, along with process energy consumption data, which is fed to the system by continuous metering. As a result, a simplified sizing calculation is carried out allowing developing an adapted energy and economic balance analysis focused on the performance of the proposed PV installation and its potential impact on the monitored process. In consequence, the tool is conceived as an advisory system allowing the user to decide whether or not carrying out a detailed study in the short or medium term.

description: Bhargava proved a formula for counting, with certain weights, degree n etale extensions of a local field, or equivalently, local Galois representations to S_n. This formula is motivation for his conjectures about the density of discriminants of S_n-number fields. We prove there are analogous ``mass formulas'' that count local Galois representations to any group that can be formed from symmetric groups by wreath products and cross products, corresponding to counting towers and direct sums of etale extensions. We obtain as a corollary that the above mentioned groups have rational character tables. Our result implies that D_4 has a mass formula for certain weights, but we show that D_4 does not have a mass formula when the local Galois representations to D_4 are weighted in the same way as representations to S_4 are weighted in Bhargava's mass formula.

description: In densely populated countries, free-field photovoltaics compete with agriculture for cultivable land. In order to meet the requirements of both, spectrally selective solar cells can be applied. While the solar cell absorbs green and near infrared light for electrical power generation, it transmits red and blue light, which is required for photosynthesis of the plants below. For the application of this solar cell type in greenhouses or facades for urban gardening, the optical performance of the solar cell under different illumination angles is crucial. In this contribution, we study the optical behavior of the cell with regard to the angle dependence of the spectral selectivity by simulation and experimental validation. The results are used to consider the application of the spectrally selective solar cell and to estimate the benefit of the system integration.

description: The advanced complex electronic systems increasingly demand safer and more secure hardware parts. Correspondingly, fault injection became a major verification milestone for both safety- and security-critical applications. However, fault injection campaigns for gate-level designs suffer from huge execution times. Therefore, designers need to apply early design evaluation techniques to reduce the execution time of fault injection campaigns. In this work, we propose a method to represent gate-level Single-Event Transient (SET) faults by multiple Single-Event Upset (SEU) faults at the Register-Transfer Level. Introduced approach is to identify true and false logic paths for each SET in the flip-flops fan-in logic cones to obtain more accurate sets of flip-flops for multiple SEUs injections at RTL. Experimental results demonstrate the feasibility of the proposed method to successfully reduce the fault space and also its advantage with respect to state of the art. It was shown that the approach is able to reduce the fault space, and therefore the fault-injection effort, by up to tens to hundreds of times.

PV Module Design, Manufacture, Performance and Reliability

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 1187-1191
description: The photovoltaic (PV) market has seen the introduction and withdrawal of numerous PV cell and module technologies during the past years. The success of certain technologies is closely tied to their long-term reliability and energy yield (EY) performance. Bifacial PV modules are rapidly increasing their market share, inducing adaptations of existing PV standards, modifications in the current measurement and installation practices. While the benefit of their bifaciality is advertised with gains of up to 30 % [1], realistic benchmarking tests are needed to gain information on gains for different mounting configurations, surface albedos, climates and bifacial coefficients. The investigation of the long-term performance of bifacial PV modules requires detailed monitoring of the environmental conditions of the front and rear side as well as an in-depth analysis of the influencing factors. The aim of this work by TÜV Rheinland Energy GmbH (TRE) is the analysis of the energy yield performance of two bifacial and four monofacial PV module types during a one-year outdoor exposure in the dry desert climate of Arizona, USA.

description: In many application scenarios, outliers can be associated with specific importance for various reasons. In such cases, labeling outliers is important to connect them to the actual semantics of the respective entity. In this paper, we present a cost-based greedy approach that places labels with outliers within scatterplots. The approach uses a search strategy to find the position that represents the least cost to place labels. Our approach can also produce different labeling outcomes by adjusting the weights of the criteria of the cost function. We demonstrate our approach with scatterplots produced from object-oriented software metrics, where outliers often relate to bad smells in the software.

description: The Galactic Center (GC) region hosts a variety of powerful astronomical sources and rare astrophysical processes that emit a large flux of non-thermal radiation. The inner 375 pc x 600 pc region, called the Central Molecular Zone, is home to the supermassive black hole Sagittarius A*, massive cloud complexes, and particle accelerators such as supernova remnants. We present the results of our improved analysis of the very-high-energy (VHE) gamma-ray emission above 2 TeV from the GC using 125 hours of data taken with the VERITAS imaging-atmospheric Cherenkov telescope between 2010 and 2018. The central source VER J1745-290, consistent with the position of Sagittarius A*, is detected at a significance of 38 standard deviations above the background level $(38σ)$, and we report its spectrum and light curve. Its differential spectrum is consistent with a power law with exponential cutoff, with a spectral index of $2.12^{+0.22}_{-0.17}$, a flux normalization at 5.3 TeV of $1.27^{+0.22}_{-0.23}\times 10^{-13}$ TeV-1 cm-2 s-1, and cutoff energy of $10.0^{+4.0}_{-2.0}$ TeV. We also present results on the diffuse emission near the GC, obtained by combining data from multiple regions along the GC ridge which yield a cumulative significance of $9.5σ$. The diffuse GC ridge spectrum is best fit by a power law with a hard index of 2.19 $\pm$ 0.20, showing no evidence of a cutoff up to 40 TeV. This strengthens the evidence for a potential accelerator of PeV cosmic rays being present in the GC. We also provide spectra of the other sources in our field of view with significant detections, composite supernova remnant G0.9+0.1 and HESS J1746-285.

description: For an industry, management of the inventory of finished goods or goods to be sold is very crucial. One of the important aspects of financial analysis is the inventory turnovers for ecommerce companies. This forms a major base for decisions of the firm's management. By traditional theory of inventory, it is believes that high turn over results in stock outs and low turn over leaves high unused and outdated stock to be maintained. Thus, an effective inventory management should focus on maintaining a balance between different levels of inventory. This paper looks into the development of an analytical model for optimization of turnover ratio under well managed inventory keeping in mind the upcoming production industry. The model in this paper aims at optimizing average annual total cost and the optimum quantity of inventory, to attain maximum turnover ratio depending on various cost of involved in inventory maintenance like holding cost, procurement cost, operating cost etc.Secondly, this paper discusses about formulation of averageannual total cost function under Inventory Management Policy which can be used for effective supply chain. The results of the models are justified using comparison of initial and final values in a by hypothetical problem.

description: Pie charts and treemaps are commonly used in business settings to show part-to-whole relationships. In a study, we compare pie charts, treemaps, stacked bars, and two circular charts when answering part-to-whole questions with multiple slices and different distributions of values. We find that the circular charts, including the unusual variations, perform better than the treemap, and that their performance depends on whether participants are asked to judge the largest slice or a smaller one.

description: An intensity tracker has been developed which can be sent through belt furnaces used for thermal treatments that rely on illumination for heating and/or excess charge carrier generation. The device allows for spatially resolved measurements of illumination profiles and can be used to optimize and monitor illumination intensity within the furnaces. The crucial design aspects such as thermal management and the impact of sensor element size on sensitivity are discussed.
Underemployment and the Chinese immigrant of former professional status : a qualitative -- exploratory study
Creators: name: Chung, Rosamond C.
Publisher: name: University of British Columbia
Year: 2010

description: A qualitative - exploratory study was conducted to investigate the experiential consequences of underemployment for Chinese immigrants who were former professionals in their country of origin. Twelve male immigrants aged 28 to 63 who have resided in Canada 1 to 4 years were interviewed. For the most part, the study was existentially based using a phenomenological - content analysis format to derive results. Results indicated that Chinese immigrants' problematic responses to underemployment differed greatly depending upon their initial place of origin i.e., familiarity with and adaptability to the host society being the significant factor. Counseling suggestions to assist these individuals followed the existential paradigm. Finally, several possibilities that exist for further research into this topic of the underemployed immigrant are described.

description: The effect of the connection of different, shaded or damaged module on the performance of the whole string or the photovoltaic (PV) panel connected to a single inverter is very often discussed. Although there exist the means for protecting the PV system against negative influence of connecting PV modules with different parameters into one system (diodes, power optimizers), the real impact is not examined anymore. The simulation tools presume the connection of the same module type with same parameters and the differences are discussed only theoretically. The simulations performed in the SPICE program rather indicate that with less damage, one different module should not have a significant effect on the power drop, even in the theoretical case that no bypass diode is included in the string. The results of simulation as well as the measurement on the real system with modules with different parameters are presented in this work.

description: Below the Kondo temperature the heavy Fermion compound YbRh$_{2}$Si$_{2}$ shows a well defined Electron Spin Resonance (ESR) with local Yb$^{3+}$ properties. We report a detailed analysis of the ESR intensity which gives information on the number of ESR active centers relative to the ESR of well localized Yb$^{3+}$ in YPd$_3$:Yb. The ESR lineshape is investigated regarding contributions from itinerant centers. From the ESR of monoisotopic $^{174}$YbRh$_{2}$Si$_{2}$ we could exclude unresolved hyperfine contributions to the lineshape.

description: We outline a strategy of how to search for QCD instantons of invariant mass 20 -- 60 GeV in diffractive events in low luminosity runs at the LHC. We show that by imposing appropriate selection criteria on the final states, one can select the kinematic regime where the instanton signal exceeds the background by a factor of at least 8. In spite of the relatively strong cuts that we impose on the total transverse energy and the number of charged tracks, $\sum_i E_{T,i}>15$ GeV, $N_{\rm ch}>20$ measured within the $0

description: In this work we have characterized screen-printed passivating contacts formed by different commercially available fire-through pastes on phosphorus doped (n+) polysilicon (poly-Si) layers at the rear side of monoPolyTM solar cells. Extremely low recombination current density under metal contacts (J01,metal) of 35-45 fA/cm2 and excellent contact resistivity (c) values of ~1.3 mΩ-cm2 are obtained for two different thicknesses of poly-Si (150 nm and 250 nm) used in this work. We observe although the metal induced recombination increases with reducing thickness of the poly-Si layer, thinner poly-Si layers can lead to higher efficiencies on account of reduced parasitic absorption leading to higher short-circuit current. A champion efficiency of 22.6% having 5 busbars is reported for monoPolyTM cells with the best performing FT paste on large area (244.3 cm2) commercially available Czochralski grown Si wafers.

description: With the inclusion of photovoltaic products within the scope of the Ecodesign Working Plan 20162019, the European Commission launched in 2017 a preparatory study to assess the feasibility of implementing sustainable policy instruments to photovoltaic modules, inverters and systems with the aim of creating a more sustainable European PV market. The considered policy tools include the mandatory Ecodesign and Energy Labelling, and the voluntary Ecolabel and Green Public Procurement. In parallel, a dedicated study to model the performance of the said PV products was launched to support the implementation of the policy instruments. Based on existing standards, a methodology to estimate the lifetime AC energy yield of PV systems has been developed, modelling independently the performance of the various components. The method is a compromise between accuracy and available information, which in some cases limits the model to be implemented. The complete methodology takes into consideration the efficiency of the various components, and aspects like degradation, losses and lifetime, some of which are not covered by available standards. For these cases, transitional methods were proposed and implemented until international or European standards are developed. The present paper describes the methodology developed in the said modelling study and the conclusions reached.

description: It is now well established that stellar winds of hot stars are fragmentary and that the X-ray emission from stellar winds has a strong contribution from shocks in winds. Chandra high spectral resolution observations of line profiles of O and B stars have shown numerous properties that had not been expected. Here we suggest explanations by considering the X-rays as arising from bow shocks that occur where the stellar wind impacts on spherical clumps in the winds. We use an accurate and stable numerical hydrodynamical code to obtain steady-state physical conditions for the temperature and density structure in a bow shock. We use these solutions plus analytic approximations to interpret some major X-ray features: the simple power-law distribution of the observed emission measure derived from many hot star X-ray spectra and the wide range of ionization stages that appear to be present in X-ray sources throughout the winds. Also associated with the adiabatic cooling of the gas around a clump is a significant transverse velocity for the hot plasma flow around the clumps, and this can help to understand anomalies associated with observed line widths, and the differences in widths seen in stars with high and low mass-loss rates. The differences between bow shocks and the planar shocks that are often used for hot stars are discussed. We introduce an ``on the shock'' (OTSh) approximation that is useful for interpreting the X-rays and the consequences of clumps in hot star winds and elsewhere in astronomy.

Creating Interactive Scientific Publications using Bindings

description: Many scientific publications report on computational results based on code and data, but even when code and data are published, the main text is usually provided in a separate, traditional format such as PDF. Since code, data, and text are not linked on a deep level, it is difficult for readers and reviewers to understand and retrace how the authors achieved a specific result that is reported in the main text, e.g. a figure, table, or number. In addition, to make use of new the opportunities afforded by data and code availability, such as re-running analyses with changed parameters, considerable effort is required. In order to overcome this issue and to enable more interactive publications that support scientists in more deeply exploring the reported results, we present the concept, implementation, and initial evaluation of bindings. A binding describes which data subsets, code lines, and parameters produce a specific result that is reported in the main text (e.g. a figure or number). Based on a prototypical implementation of these bindings, we propose a toolkit for authors to easily create interactive figures by connecting specific UI widgets (e.g. a slider) to parameters. In addition to inspecting code and data, readers can then manipulate the parameter and see how the results change. We evaluated the approach by applying it to a set of existing articles. The results provide initial evidence that the concept is feasible and applicable to many papers with moderate effort.
