description: We construct a dual description of technicolor theory based on the D4/D8 brane configuration. A strongly-coupled technicolor theory is identified as the effective theory on D-branes, and from the gauge/gravity correspondence, we explore the weakly-coupled holographic description of dynamical electroweak symmetry breaking. It is found from the D-brane probe action that the masses of W and Z bosons are given by the decay constant of technipion, and the technimesons become hierarchically heavy. Moreover, the couplings of heavier modes to standard model fermions are rather suppressed. The oblique correction parameters are also evaluated and found to be small except for the S parameter, which can be reduced by modifying the model. The fermion fields are introduced at the intersections of D-branes and their masses are generated via massive gauge bosons from open strings stretching between D-branes.

description: This study presents the development and application of an adjoint model for investigating the sensitivity of solar radiation to forecasted variables from Weather Research and Forecasting-Solar (WRF-Solar). The first part of this study focuses on developing an adjoint model for the Fast All-sky Model for Solar Applications (FARMS) to investigate the input variables having the highest sensitivity to global horizontal irradiance, direct normal irradiance, and diffuse horizontal irradiance, which are the output variables. The applicability and usefulness of the adjoint sensitivity approach are demonstrated by conducting a sensitivity analysis under various scenarios defined by low, medium, and high values for the input variables. This preliminary study uses elasticity values to understand the sensitivity of solar radiation to the input variables (e.g., solar zenith angle, Ångström turbidity coefficient, and cloud optical depth) of FARMS. This presentation will illustrate the implemented methodology and the obtained sensitivity results for FARMS as well as future research steps that will lead to the development of high-quality probabilistic solar forecasts.

description: A layer of sand of thickness h flows down a rough surface if the inclination is larger than some threshold value theta which decreases with h. A tentative microscopic model for the dependence of theta with h is proposed for rigid frictional grains, based on the following hypothesis: (i) a horizontal layer of sand has some coordination z larger than a critical value z_c where mechanical stability is lost (ii) as the tilt angle is increased, the configurations visited present a growing proportion $_s of sliding contacts. Instability with respect to flow occurs when z-z_s=z_c. This criterion leads to a prediction for theta(h) in good agreement with empirical observations.

description: We present further arguments that the Hipparcos parallaxes for some of the clusters and associations represented in the Hipparcos catalog should be used with caution in the study of the Galactic structure. It has been already shown that the discrepancy between the Hipparcos and ground based parallaxes for several clusters including the Pleiades, Coma Ber and NGC 6231 can be resolved by recomputing the Hipparcos astrometric solutions with an improved algorithm diminishing correlated errors in the attitude parameters. Here we present new parallaxes obtained with this algorithm for another group of stars with discrepant data - the galactic cluster Cr 121. The original Hipparcos parallaxes led de Zeeuw et al. to conclude that Cr 121 and the surrounding association of OB stars form a relatively compact and coherent moving group at a distance of 550 -- 600 pc. Our corrected parallaxes reveal a different spatial distribution of young stellar populace in this area. Both the cluster Cr 121 and the extended OB association are considerably more distant (750 -- 1000 pc), and the latter has a large depth probably extending beyond 1 kpc. Therefore, not only are the recalculated parallaxes in complete agreement with the photometric uvbybeta parallaxes, but the structure of the field they reveal is no longer in discrepancy with that found by the photometric method.

Geology and genesis of the midway silver-lead-zinc deposit, north-central British Columbia
Creators: name: Bradford, John Allan
Publisher: name: University of British Columbia
Year: 2010

description: The Midway Ag-Pb-Zn manto deposit is hosted in Middle Devonian McDame Group limestones of the Cassiar Terrane, a displaced segment of the North American miogeocline. In the map area (1040/16), platformal carbonates and siliciclastics of Cambrian to Devonian age are unconformably overlain by Devono-Mississipian basinal sediments, including exhalites (Earn Group). These are structurally overlain, above a flat lying decollement, by Upper Paleozoic marginal basin sediments, basaltic volcanics, intrusives and ultramafites (Sylvester allochthon). The decollement represents the boundary between Cassiar Terrane and Slide Mountain Terrane in the map area. Jurassic contraction of the North American margin and emplacement of the Sylvester allochthon produced southeasterly trending major and minor structures. Cretaceous - Tertiary extension, linked to transcurrent motion along the Kechika and related faults, produced the north trending high angle Tootsee River fault zone, which divides the map area. Two intrusive suites, of mid-Cretaceous (100 Ma) and Late Cretaceous (70 Ma) ages, are documented by K-Ar dating. The Late Cretaceous episode is evidenced by large sericite - pyrite alteration zones southeast of Midway, but only a few felsic porphyry dykes are exposed at current erosion levels. High angle faults in the Tootsee River fault zone confined intrusion driven hydrothermal fluid migration up plunge from an intrusive centre about 2 kilometres southeast of Midway. Fluids were ponded in a southeasterly plunging antiformal trap, and massive sulphides deposited in zones of pre-existing karst breccia porosity beneath a relatively impermeable shale cap. Fe and Cu rich pyrrhotitic assemblages occur at greater depth toward the intrusive centre, with sulphosalt rich pyritic assemblages at shallower depths to the north. Immiscible aqueous - carbonic liquid and vapour were trapped in quartz deposited with sulphides at 300-340OC. Later lower temperature inclusions record the progressive loss of CH₄ and CO₂ from the system. Salinities were about 7-10 weight % NaCl equivalent. Sulphur isotopes of sulphides span a narrow range, indicating a well mixed reservoir and H₂S dominated environment. Both sedimentary and igneous sources are indicated. Oxygen isotopes of carbonates demonstrate large ¹⁸O depletions due to extensive meteoric water interaction. In a regional context (Rancheria silver district), Midway lead isotopes suggest mixing of upper crustal lead from country rocks with intrusion derived lower crustal lead. Cassiar Terrane epigenetic deposits are distinguished from epigenetic deposits of Slide Mountain Terrane, which have significant mantle lead, consistent with derivation from oceanic and arc host rock assemblages.

description: TOPCon is an appealing choice for next-generation solar cells as it minimizes surface recombination, enables low contact resistivities, and provides high thermal stability thereby rendering it compatible with screen-printed metallization. While TOPCon is commonly realized by low-pressure chemical vapor deposition (LPCVD), this paper discusses the use of a plasma-enhanced chemical vapor deposition (PECVD) tool, which are commonly used for deposition of SiNx or AlOx. It will be shown that thick screen-printing compatible TOPCon layers providing excellent surface passivation can be realized with such tool. Additionally, the firing stability of TOPCon/SiNx stack will be discussed and first solar cell results will be presented. The IV parameters of the best solar cell were: Voc = 691.2 mV, FF = 80.7%, Jsc = 40.4 mA/cm², and = 22.5%.

description: We show that strong non--linear electron transport in the ferromagnetic insulating (FMI) state of manganites, responsible for phenomena such as colossal electroresistance and current induced resistance switching, can occur due to a hot electron effect. In the FMI state, which we show is an insulator with a Coulomb gap, the temperature of the electron and lattice baths can decouple at high input power levels, leading to heating of the electron bath. Parameters of the hot electron effect model were independently determined via time dependence experiments and are in good agreement with the experimental values.

description: Aerial infrared thermography (aIRT) has become an important method for the fault inspection of large, utility-scale photovoltaic (PV) plants. The method uses an infrared (IR) camera mounted on a drone to detect the faults, which produce changes in the thermal behaviour of PV modules, in an efficient manner. There is plenty of research in the field for crystalline silicon modules, but not for thin-film PV technologies. In this work, a CIGS thin-film PV plant is inspected by aIRT in order to investigate this process and to find which faults can be detected by aIRT. The inspection at 20 m altitude of the 1 MWp plant of 1.4 hectares took about 12 minutes, and the analysis of the video data about 30 minutes. Such an inspection allows the detection of the following faults: disconnected strings, short-circuits, bypassed modules, most of the cell breaks, hot junction boxes and bad soldering problems. Other faults could not be detected by this method, namely glass breaks and certain cell breaks.

PV Module Design, Manufacture, Performance and Reliability

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 789-794
description: Photovoltaic Module product development is still very much based on cost pressure, experience, empirical rules, partly on design of experiments and therefore extensive testing compared to e.g. the automotive or wind power industry. Many aspects are evaluated by testing physical prototypes and with classic trial & error further understanding of the products is achieved slowly. This procedure is time-consuming and costly. Utilizing modern sim-ulation methods, the time-consuming production and testing of physical prototypes can be reduced significantly. Mean-while, several simulation models for the evaluation of optical, electrical, thermal and mechanical properties as well as performance simulation software are available. In the specific case of mechanical optimization, the failure modes such as glass breakage, cell breakage and interconnection failure have been addressed in the past by Fraunhofer CSP with the help of simulation methods. In this paper the focus lays on the process of digital prototyping. A concept is presented to do digital prototyping combining finite element simulations, known stress factors from the field and material parameters. It is demonstrated how new technology such as multi-busbar (>3BB), double glass modules or new encapsulant materials influence mod-ule reliability. Based on the results, recommendations for the construction of demonstrator modules in the Fidelitas project were derived to improve reliability and service life.

description: We construct a large class of quantum "d x d" states which are positive under partial transposition (so called PPT states). The construction is based on certain direct sum decomposition of the total Hilbert space displaying characteristic circular structure - that is way we call them circulant states. It turns out that partial transposition maps any such decomposition into another one and hence both original density matrix and its partially transposed partner share similar cyclic properties. This class contains many well known examples of PPT states from the literature and gives rise to a huge family of completely new states.

description: This paper presents a quantitative data analysis of smart wet appliances in two residential smart grids. The energy consumption patterns and flexibility of 175 smart washing machines and 9 smart dishwashers’ data were analyzed for the whole year (5 min. resolution, monitoring fraction > 90%) on two Dutch smart grid pilots; Jouw Energy Moment (JEM) 2014 and PowerMatching City (PMC) 2012. The research results show annual use of 540 hours of wet appliances for an average household. Besides, 770 hours of flexibility are realized annually thanks to users’ active participation and the energy management systems that were employed. In conclusion, energy demand could be identified as self-consumption for almost half of the smart appliances’ consumption in both pilots (PMC: 47%, JEM: 45%), showing a noticeable consumption shifted towards solar self-consumption.

This also naturally gives the criteria for the mean-field one- and two-dimensional regimes. Our predictions, including the Thomas-Fermi density profiles, are shown to be in excellent agreement with numerical solutions. Importantly, the anisotropy of the interactions has a profound effect on the Thomas-Fermi/low-dimensional criteria.

description: This paper presents a simple and non-destructive method to determine doping densities and built-in potential of subcells by adapting the well-known capacitance-voltage (C-V) technique to two-terminal (2T) tandem solar cells. Because of the electrical coupling between the two subcells in a monolithic 2T tandem solar cell the standard method using a Mott-Schottky plot (1/C2 vs. V) cannot be applied. Using numerical modeling, it is demonstrated that, by under chosen illumination conditions where only one subcell can absorb the light, it is possible to explore the bias dependence of the capacitance and to extract the parameters of the other subcell if the appropriate frequency conditions are present. This method is experimentally applied to an AlGaAs/Si tandem cell and parameters of both AlGaAs and Si cells are extracted. Finally, the validity of that method is assessed by the very good agreement obtained when comparing the values extracted from our measurements on the tandem cell to those extracted from measurements on isotype cells and to the values targeted during the fabrication process of the AlGaAs/Si tandem solar cell.

description: The connection of solar PV system to the grid, with intermittent characteristic, can raise several technical problems or can have significant impacts on power systems [1], in particular the modification of the voltage profile and power flows on the network. This is why, the aim of this paper is focused on the voltage control in grids by two strategies: local and coordinated control. For the first strategy, a local control for PV systems has been developed on fuzzy logic. The developed auto-adaptive control presents advantages such as local decisions based only on local measures. This avoids investments on communication systems for DNOs. This control is not only able to control the voltage at the connection point but also to make others PV systems participate to the voltage control on the grid. This solution is implemented in real inverters via a micro-controller and evaluated in a real grid with satisfied result. For the second strategy, a coordinated voltage control for PV systems including Onload Tap Changers (OLTC) has been developed. This approach used model predictive control (MPC) is finding greater relevance due to many advantages offered by it such as natural handling of multivariable control problems, ability to maintain voltage in limits and to reduce power losses in grid.
Radio Resource and Beam Management in 5G mmWave Using Clustering and Deep Reinforcement Learning

description: To optimally cover users in millimeter-Wave (mmWave) networks, clustering is needed to identify the number and direction of beams. The mobility of users motivates the need for an online clustering scheme to maintain up-to-date beams towards those clusters. Furthermore, mobility of users leads to varying patterns of clusters (i.e., users move from the coverage of one beam to another), causing dynamic traffic load per beam. As such, efficient radio resource allocation and beam management is needed to address the dynamicity that arises from mobility of users and their traffic. In this paper, we consider the coexistence of Ultra-Reliable Low-Latency Communication (URLLC) and enhanced Mobile BroadBand (eMBB) users in 5G mmWave networks and propose a Quality-of-Service (QoS) aware clustering and resource allocation scheme. Specifically, Density-Based Spatial Clustering of Applications with Noise (DBSCAN) is used for online clustering of users and the selection of the number of beams. In addition, Long Short Term Memory (LSTM)-based Deep Reinforcement Learning (DRL) scheme is used for resource block allocation. The performance of the proposed scheme is compared to a baseline that uses K-means and priority-based proportional fairness for clustering and resource allocation, respectively. Our simulation results show that the proposed scheme outperforms the baseline algorithm in terms of latency, reliability, and rate of URLLC users as well as rate of eMBB users.

Heterojunction Solar Cells

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 558-563
description: The fabrication process of silicon heterojunction (SHJ) solar cells can induce locally depassivated regions (so-called defectivity) because of transportation steps (contact with belts, trays, etc) or simply the environment (presence of particles embedded within surface thin films). This surface passivation spatial heterogeneity is gaining interest as it may hinder the SHJ efficiency improvements allowed by incremental process steps optimizations. An experimentally-supported simulation study is proposed and applied on full size M2 SHJ cells in order to understand how the local a-Si:H/c-Si interface passivation loss impacts the overall cell performance. A simulation framework (developed on ATLAS Silvaco) was first validated through comparisons with experimental results. This step allowed then to use simulations results further to explore and understand the physics behind the defectivity-induced efficiency loss. The cell performance drop due to depassivated regions was attributed to a bias-dependent minority carrier recombination current flow towards the depassivated region, which is shown to affect mainly the Fill Factor.

description: Nowadays, electroluminescence imaging (Eli) appears as an emerging technique in the maintenance of photovoltaic (PV) plants. There is a concern about how the current injection needed in ELi measurements can affect the PV modules service life, and how these periodical inspections can affect the long term life of the modules. In order to give a practical answer to this problem, a series of tests consisting of long periods of current injection on several monocrystalline silicon modules has been carried out. The modules tested had already fulfilled their useful life and present multiple defects. In order to analyze how the current injection affects the state of the module, images of infrared thermography (IRT) and ELi were acquired during the current injection period. The subsequent analysis of these images shows only a small effect during the heating period in the EL intensity results at the beginning of each test, not affecting the module performance.

description: We study the origin of the intrinsic spin Hall conductivity (SHC) and the d-orbital Hall conductivity (OHC) in Pt based on a multiorbital tight-binding model with spin-orbit interaction. We find that the SHC reaches 1000 \hbar/eΩcm when the resistivity ρis smaller than ~10 μΩcm, whereas it decreases to 300 \hbar/eΩcm when ρ~ 100 μΩcm. In addition, the OHC is still larger than the SHC. The origin of huge SHE and OHE in Pt is the large ``effective magnetic flux'' that is induced by the interorbital transition between d_{xy}- and d_{x2-y2}-orbitals with the aid of the strong spin-orbit interaction.

Design and Installation of PV Systems

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 1261-1265
description: Bifacial photovoltaic technology is a promising, new approach to further reducing the Levelized Cost of Electricity of photovoltaic-generated electricity. However, designing and optimizing bifacial photovoltaic plants is a challenging task, which requires new modelling tools. This paper presents a physics-based energy yield simulation approach for bifacial photovoltaic systems, providing accurate yield prediction and insight into the operation of bifacial PV systems. Rear-side, inhomogeneous illumination is modelled using a CAD-assisted, GPU-accelerated ray-tracing-based approach, considering the influence of module build-up and layout, module frame, mounting structure and environment geometry. The non-uniform electrical-thermal operation with geometry-dependent convective and radiative cooling mechanisms and the resulting mismatch effect, which reduces module and system power output is modelled via interconnected electrical and thermal-equivalent circuits, where time-varying thermal resistors are used to model convective and radiative cooling. The combination of high-performance computing techniques, with advanced daylighting and circuit computing algorithms provides high accuracy at low computational costs, ensuring practical applicability to designing photovoltaic power generation system. The presented outdoor validation study confirms that our approach results in high accuracy, since the main mechanisms taking place during photovoltaic energy conversion are modelled on a physics basis. Additionally, physics-based modelling provides insight into the operation, the main loss contributions and mitigation strategies, applicable to bifacial PV systems.

description: We present a gauge formulation of the special affine algebra extended to include an antisymmetric tensorial generator belonging to the tensor representation of the special linear group. We then obtain a Maxwell modified metric affine gravity action with a cosmological constant term. We find the field equations of the theory and show that the theory reduces to an Einstein-like equation for metric affine gravity with the source added to the gravity equations with cosmological constant μcontains linear contributions from the new gauge fields. The reduction of the Maxwell metric affine gravity to Riemann-Cartan one is discussed and the shear curvature tensor corresponding to the symmetric part of the special linear connection is identified with the dark energy. Furthermore, the new gauge fields interpreted as geometrical inflaton vector fields which drive accelerated expansion.

description: We consider Yang-Mills theory with the U(1) gauge group on a non-commutative plane. Perturbatively it was observed that the invariance of this theory under area-preserving diffeomorphisms (APDs) breaks down to a rigid subgroup SL(2,R). Here we present explicit results for the APD symmetry breaking at finite gauge coupling and finite non-commutativity. They are based on lattice simulations and measurements of Wilson loops with the same area but with a variety of different shapes. Our results are consistent with the expected loss of invariance under APDs. Moreover, they strongly suggest that non-perturbatively the SL(2,R) symmetry does not persist either.

description: The objective of this paper was to evaluate different load management strategies for weak grids with high penetration of electrical vehicles. The strategies are intended to operate distribution grids close to their physical and operational limits, which are the current rating of the cables and the voltage level for the safe operation of the applied load. Distribution networks are dimensioned based on the expected loads and their simultaneity factor. Problems will occur if the loads exceed the original specification or operation durations. The presented paper addresses the evaluation of load management strategies for two different network topologies. One topology is a stab line which is most sensitive for problems with the supplied operation voltage at the last access point. The second topology is a randomly chosen topology. Five different load management strategies including: Immediate Acceptance (IA), Time Based Shift as Whole (TSW), Time Based Shift and Dispatching for All Remaining Loads (TSD), Time based Shift and Split (TSS), and Optimized Split (OS) were identified and simulated over the selected topologies. Maximizing the load acceptance rate (%) and the total delivered energy (MWh) are identified as the two main parameters to be calculated, optimized and compared amongst strategies.

description: A non-supersymmetric grand unified theory can exhibit a "radiative fermion mass hierarchy", in which the heavier quarks and leptons get mass at tree level and the lighter ones get mass from loop diagrams. Recently the first predictive model of this type was proposed. Here it is analyzed numerically and it is shown to give an excellent fit to the quark and lepton masses and mixings, including the CP phase violating phase $δ_{CKM}$. A relation between the neutrino angle $θ_{13}$ and the atmospheric neutrino angle is obtained

description: Silicon-rich nitride (SRN) is explored as an alternative to poly-Si for use in poly-Si/SiOx type passivating contact for silicon solar cells. We show that by incorporating nitrogen in silicon films during deposition by PECVD, it is possible to achieve high bandgap silicon-rich films, which are also highly blister-resistant. Micro-structural characterization of the SRN films revealed Si crystallite formation upon annealing the films at 950 °C. We also show that excellent surface passivation of n-type Cz Si wafers, can be achieved after FGA by using SRN on top of thin (1.4 nm) SiOx even without using any intentional doping. However, passivation quality of the SRN-on-SiOx stack after the crystallisation anneal at 950 °C and FGA treatment exhibits severe degradation. Nevertheless, effective lifetimes above 1 ms at an injection level of 1015 cm-3 can be achieved. Moreover, a SRN layer thickness-dependent behavior of passivation was observed.

Accelerating collaborative data sharing with SmartFigures

Subjects: Open Science
Publishing

description: The SourceData platform developed by EMBO enhances access to published research data and the related methodologies with the goal of accelerating scientific discovery. SourceData curates the figures of scientific papers as part of the publishing workflow of EMBO Press journals and automatically deposits the underlying source data in the EMBL-EBI BioStudies database. The curated figures are made openly accessible as ‘SmartFigures’, which are enhanced interconnected figures that provide direct access to the underlying source data. SmartFigures are searchable based on the curated metadata by the SourceData’s semantic search engine or via Google Dataset Search. To date, the SourceData database includes more than 40,000 curated experiments.
 As companion application to SourceData, we are developing the community-oriented open-source SDash platform that allows researchers to share scientific findings in the form of SmartFigures. With SDash, scientists can very easily create SmartFigures that then serve as an intuitive way to organise research data. Sharing within trusted user groups in combination with online commenting promotes discussions and exchange with collaborators prior to global open dissemination and publication. Authoring functionalities allow users to add figure description, structured keywords, link data files, computer scripts, and protocols, thus making the research results more useful and transparent to the community. By providing a user-friendly platform for sharing scientific results, SDash aims at lowering the barrier for open dissemination, exchange of findings and constructive debates. Ultimately, this figure-centric approach to early data sharing will also ease the preparation of materials for journal articles, conference presentations, posters, lab talks and lectures.

description: We calculate the quasi-normal modes of black holes localized on a 3-brane of finite tension embedded in six-dimensional flat spacetime. Using the WKB approximation, we obtain the frequencies of various types of perturbation both analytically and numerically for arbitrary brane tension. We thus extend earlier analytical results which were derived for a brane of small tension.

description: In this work, we report results from the EU-funded project ARCIGS-M. The project started in 2016 and aims to reduce the use of indium and gallium by enabling the use of very thin Cu(In,Ga)Se2 (CIGS) layers while retaining high efficiency and developing innovative low-cost steel substrates as alternatives to glass. In the project, reflective layers containing TCO´s and silver have successfully been used to enhance the reflective properties of the rear contact. In addition, passivation layers based on alumina (Al2O3) deposited by atomic layer deposition (ALD) have been found to yield good passivation of the rear contact. Since the alumina layers are dielectric, perforation of these layers is necessary to provide adequate contacting. The design of the perforation patterns has been investigated by a combination of modeling and experimental verification by electron beam lithography. In parallel a nano-imprint lithography (NIL) process is further developed for scale-up and application in prototype modules. Advanced optoelectrical characterization supported by modeling is used to fill in the missing gaps in optical and electrical properties, regarding CIGS, interfaces and back contact materials.

Structure analysis of interstellar clouds: I. Improving the Delta-variance method

description: The Delta-variance analysis, has proven to be an efficient and accurate method of characterising the power spectrum of interstellar turbulence. The implementation presently in use, however, has several shortcomings. We propose and test an improved Delta-variance algorithm for two-dimensional data sets, which is applicable to maps with variable error bars and which can be quickly computed in Fourier space. We calibrate the spatial resolution of the Delta-variance spectra. The new Delta-variance algorithm is based on an appropriate filtering of the data in Fourier space. It allows us to distinguish the influence of variable noise from the actual small-scale structure in the maps and it helps for dealing with the boundary problem in non-periodic and/or irregularly bounded maps. We try several wavelets and test their spatial sensitivity using artificial maps with well known structure sizes. It turns out that different wavelets show different strengths with respect to detecting characteristic structures and spectral indices, i.e. different aspects of map structures. As a reasonable universal compromise for the optimum Delta-variance filter, we propose the Mexican-hat filter with a ratio between the diameters of the core and the annulus of 1.5.
