description: Distributed Energy Resources (DERs) equipped with standardized, interoperable, grid-support functionality have the capability to provide a range of services for power system operators. These requirements have been recently codified in the 2018 revision of the American DER interconnection and interoperability standard, IEEE Std. 1547, as well as the revised Canadian interconnection standard, CSA C22.3 No. 9. Currently, the IEEE standards committee is drafting a new revision of the IEEE Std. 1547.1 test standard, which outlines the test procedures for certifying equipment compliant to IEEE Std. 1547. In addition, it is often referenced as a test standard in CSA C22.3 No. 9. This draft test standard has not been fully exercised yet to identify mistakes, redundancies, and/or implementation challenges. In this work, an international community of research laboratories developed open-source IEEE Std. 1547.1 test scripts. The scripts are used to evaluate grid-support functions – such as constant-power-factor, volt-var, volt-watt, and frequency-watt functions – of several DER devices to the draft standard, IEEE1547.1. Sample test results are presented and discussed, and recommendations are offered to improve the draft standard during the balloting process.

description: Over the last twenty years the CHI conference has grown substantially. However, with the reframing of climate change as a climate crisis, environmental concerns have become increasingly pervasive in the community. In 2019 CHI introduced a sustainability role and set a goal to make CHI more sustainable. In 2020 CHI is in Hawaii. This work looks back over the last two decades and estimates what are substantial and growing CO2 emissions from conference travel. First, it posits how, in the short term, potential environmental damage can be minimised. Second, and longer-term, it invites the community to reflect on research dissemination and how the conference experience may need to change.

PV Module Design, Manufacture, Performance and Reliability

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 860-865
description: Electroluminescence (EL) imaging of photovoltaic (PV) modules requires careful selection of the measurement parameters, such as camera sensor exposure time, for obtaining accurate images for qualitative and quantitative evaluation of PV module failures. In this work we propose a method for determining the optimal exposure time for EL imaging of PV panels, with respect to maximizing the utilized camera sensitivity range and limiting image saturation due to overexposure. The method requires two EL measurements of the PV panel, at two distinct exposure times, that are used to calculate the optimal exposure time. The main advantage of the proposed method over manually calibrating the exposure time of the camera is that it can be integrated in the camera image acquisition application, for automatic exposure time calibration.
Collapse times for attractive Bose-Einstein condensates

Subjects: subject: Other Condensed Matter (cond-mat.other)

description: We argue that the main mechanism for condensate collapse in an attractive Bose-Einstein condensate is the loss of coherence between atoms a finite distance apart, rather than the growth of the occupation number in noncondensate modes. Since the former mechanism is faster than the latter by a factor of approximately 3/2, this helps to dispel the apparent failure of field theoretical models in predicting the collapse time of the condensate.

description: We are pleased to present you with this book which is the effect of the international cooperation between the Research Group of the Commercial Law acting at the Faculty of Law and Administration of the University of Silesia and representatives of foreign university departments of private law from Austria, the Czech Republic, Slovakia and Ukraine. The “Evolution of Private Law – New Challenges” continues the collective publications issued in 2014, 2015 and 2017. Private law is not a subject that currently suffers from a scarcity of interesting and great scientific publications, but our first thought was to create some space for authors from different European countries to present new visions and development paths for that area of law. This year’s edition is dedicated to the new challenges facing national legislators regarding the adjustment of their legal systems to some international regulations on private law. A broad range of authors – academics from the above mentioned countries – substantially contribute to strengthen and widen the comparative law research. This publication is dedicated primarily to civil law academics, but it also addresses the issues relevant to the legal practice. Most of the articles can be useful in the didactic process at law studies as well.

description: We compare light-and-elevated-temperature-induced-degradation (LeTID) activities in both p- and ntype lifetime samples made from mono-like silicon (ML-Si) and float-zone silicon (FZ-Si) materials, and investigate their dependence on SiNx film properties. All four materials show degradation behaviour upon illumination at elevated temperature. We observe a smaller, but still noticeable lifetime degradation in the studied n-type ML-Si and FZ-Si samples when comparing with the p-type samples. A similar capture cross section ratio of 20 ± 7 is determined from injection dependent lifetime spectroscopy (IDLS) for the p-type ML-Si and FZ-Si samples, assuming a mid-gap defect. The studied n-type samples, on the other hand, show significantly less injection dependent lifetime behaviours. Moreover, it is found that LeTID phenomena is strongly related to the SiNx film properties. Samples coated with SiNx films deposited at higher temperature suffer more severe lifetime degradation, despite containing less amount of hydrogen in the films.
Spin-magnetophonon level splitting in semimagnetic quantum wells

description: Spin-magnetophonon level splitting in a quantum well made of a semimagnetic wide gap semiconductor is considered. The semimagnetic semiconductors are characterized by a large effective $g$ factor. The resonance conditions $\hbarω_{\rm LO}=μ_BgB$ for the spin flip between two Zeeman levels due to interaction with longitudinal optical phonons can be achieved sweeping magnetic field $B$. This condition is studied in quantum wells. It is shown that it leads to a level splitting that is dependent on the electron-phonon coupling strength as well as on the spin-orbit interaction in this structure. We treat in detail the Rashba model for the spin-orbit interaction assuming that the quantum well lacks inversion symmetry and briefly discuss other models. The resonant transmission and reflection of light by the well is suggested as a suitable experimental probe of the level splitting.

description: The performance-enhancing effect of water-cooling on floating photovoltaic (f-PV) technologies is widely claimed, but poorly quantified and documented. In this work we aimed to analyze the performance and quantify the cooling effect of one specific f-PV technology developed by Ocean Sun AS. The technology consists of a hydroelastic floating membrane with horizontally mounted PV modules in good thermal contact with the water body. The analysis was based on data from a well instrumented 6.48 kW pilot installation at Skaftå, Norway. The pilot was installed in May 2018 and consisted of two strings of modules. In February 2019 one of the strings was slightly elevated from the membrane by plastic pipes inserted under the modules to effectively make this string air-cooled. The performance of the two strings were then directly compared. The string that was in thermal contact with water had on average 6-8% higher yield than the air-cooled string, and the difference increased to more than 10% in periods with high irradiance. Our study therefore validates claims that some f-PV technologies can provide performance enhancements in the order of 10%. However, the cooling effect, and hence the performance gain, depends critically on the installation design. It is therefore essential to clearly discern between the different types of f-PV technologies to avoid confusion regarding the magnitude of this effect.

description: Practically measurable quantities resulting from quantum field theory are not described by hermitian operators, contradicting one of the cornerstone axioms of orthodox quantum theory. This could be a sign that some of the axioms of orthodox quantum theory should be reformulated. A non-orthodox reformulation of quantum theory based on integral curves of particle currents is advocated and possible measurable manifestations are discussed. The consistency with particle creation and destruction requires particles to be extended objects, which can be viewed as a new derivation of string theory. Within this reformulation, an indirect low-energy test of string theory is also possible.

description: Poly-Si/SiOx/c-Si structures were characterized using conductive AFM (C-AFM) and Kelvin Probe Force Microscopy (KPFM) techniques with the objective to provide a better understanding of the structure, and notably the presence of nanoholes in the oxide. The observed samples include highly doped poly-Si layers annealed at different temperatures (700, 800 and 900 °C) and also intrinsic poly-Si layers. The latter layers have been in particular implemented to facilitate C-AFM and KPFM correlative analysis on the same scan areas. It is found that the C-AFM technique is not conclusive due to the high doping and surface morphology of the poly-Si layer. On the other hand KPFM allows to observe local surface potential drops that may be correlated to holes in the oxide. Correlative microscopy measurements applied on intrinsic poly-Si allowed to evidence links between C-AFM and KPFM observations, however surface conduction effects on c-AFM still remain.

description: We study the NP-hard graph problem COLLAPSED K-CORE where, given an undirected graph G and integers b, x, and k, we are asked to remove b vertices such that the k-core of remaining graph, that is, the (uniquely determined) largest induced subgraph with minimum degree k, has size at most x. COLLAPSED K-CORE was introduced by Zhang et al. (2017) and it is motivated by the study of engagement behavior of users in a social network and measuring the resilience of a network against user drop outs. COLLAPSED K-CORE is a generalization of R-DEGENERATE VERTEX DELETION (which is known to be NP-hard for all r ≥ 0) where, given an undirected graph G and integers b and r, we are asked to remove b vertices such that the remaining graph is r-degenerate, that is, every its subgraph has minimum degree at most r. We investigate the parameterized complexity of COLLAPSED K-CORE with respect to the parameters b, x, and k, and several structural parameters of the input graph. We reveal a dichotomy in the computational complexity of COLLAPSED K-CORE for k ≤ 2 and k ≥ 3. For the latter case it is known that for all x ≥ 0 COLLAPSED K-CORE is W[P]-hard when parameterized by b. For k ≤ 2 we show that COLLAPSED K-CORE is W[1]-hard when parameterized by b and in FPT when parameterized by (b + x). Furthermore, we outline that COLLAPSED K-CORE is in FPT when parameterized by the treewidth of the input graph and presumably does not admit a polynomial kernel when parameterized by the vertex cover number of the input graph.

description: Due to the rapid growth in the size and number of photovoltaic (PV) power plants, monitoring solutions that ensure a high, reliable power output and low maintenance costs are of increasing importance. Three criteria for such monitoring solutions are generality (applicability to different data sets), robustness (ability to detect faults without producing false alarms) and scalability (numerical efficiency). Using data from three MW-scale PV plants located in Sub-Saharan Africa, the Middle East and Northern Europe, a simple fault detection algorithm has been proposed in light of these criteria. The algorithm uses production data as input, filters out unwanted datapoints and calculates a performance metric with a pre-defined frequency, before using this metric to evaluate the performance of the different sub-arrays. A main contribution of this work is the proposal of a procedure for selecting filtering thresholds to reduce noise in the performance metric. We show that by applying suitable filters, the sensitivity of the fault detection algorithm is increased 2 – 5 times, greatly improving the robustness of the algorithm.

description: We have carried out density functional theory based calculations of the size dependent formation energy and geometry of Pt islands on Ru(0001), to model Pt-Ru nanocatalysts which have been recently proposed as fuel cell anode. The Pt islands are found to prefer two-dimensional structures. Furthermore, a monotonic decrease in the formation energy per Pt atom suggests a propensity of Pt atoms to wet the Ru(0001) surface. Calculated energy barriers for the diffusion of Pt monomers and dimers on the facets and through the edges of a superstructure modeling a Ru nanoparticle indicate that these edges help reduce considerably the diffusion rates across them such that the Pt atoms prefer to remain in the facet on which they were adsorbed originally and form 2D islands.

The method is based on the analysis of difference between the oscillator instantaneous phases calculated using continuous wavelet transform at time moments shifted by a certain constant value relative to each other. We apply our method to a driven asymmetric van der Pol oscillator, experimental data from a driven electronic oscillator with delayed feedback and human heartbeat time series. In the latest case, the analysis of the heart rate variability data reveals synchronous regimes between the respiration and slow oscillations in blood pressure.

description: In this paper, we present a study of daylight EL acquisition and the results of a sunlight variation study in a scenario necessary to assure the increase of EL image quality with denoising by averaging for the robustness of the drone system when bright and intermittently cloudy days occur. It was verified that the indicator of image quality based on the signal-to-noise ratio of EL images has a linear behavior with the amount of averaged images when there is no sun variation. When there are sun irradiance variation, it is observed that the quality decrease even with the increased number of images being averaged, turning to increase again only with further additional images.
A statistical study of propagating MHD kink waves in the quiescent corona

description: The Coronal Multi-channel Polarimeter (CoMP) has opened up exciting opportunities to probe transverse MHD waves in the Sun's corona. The archive of CoMP data is utilised to generate a catalogue of quiescent coronal loops that can be used for studying propagating kink waves. The catalogue contains 120 loops observed between 2012-2014. This catalogue is further used to undertake a statistical study of propagating kink waves in the quiet regions of the solar corona, investigating phase speeds, loop lengths, footpoint power ratio and equilibrium parameter values. The statistical study enables us to establish the presence of a relationship between the rate of damping and the length of the coronal loop, with longer coronal loops displaying weaker wave damping. We suggest the reason for this behaviour is related to a decreasing average density contrast between the loop and ambient plasma as loop length increases. The catalogue presented here will provide the community with the foundation for the further study of propagating kink waves in the quiet solar corona.

description: The main objective of this study is to provide an overview of the operational performance of a PV-Hybrid grid and two PV grid connected systems installed in three different countries for didactical purposes. It is possible for students to compare different systems (e.g. various solar module technologies, inverters, undersized/oversized, power of the system) in several regions. The didactical concept of this monitoring project lies on the possibility to display data in real time for different locations with different geographic characteristics. This generates some new tasks for students e.g. comparison of performance ratios, impact of the temperature on the power output, evaluation of the efficiency of the panels, considering the technologies installed, inverters efficiency.

description: We adapt a number-theoretic technique of Yu to prove a purely analytic theorem: if f(x) is in L^1 and L^2, is nonnegative, and is supported on an interval of length I, then the supremum of the convolution f*f is at least 0.631 \| f \|_1^2 / I. This improves the previous bound of 0.591389 \| f \|_1^2 / I. Consequently, we improve the known bounds on several related number-theoretic problems. For a subset A of {1,2, ..., n}, let g be the maximum multiplicity of any element of the multiset {a+b: a,b in A}. Our main corollary is the inequality gn>0.631|A|^2, which holds uniformly for all g, n, and A.

description: Questo studio propone una sintesi sulle strategie d?insediamento dei siti della cultura delle Terramare messa in atto sulla base di due differenti approcci : geomorfologico da un lato e spaziale dall?altro. La cultura delle Terramare si � sviluppata, tra le altre cose, grazie alle migrazioni di popolazioni che dopo aver occupato la pianura emiliana a sud del Po l?hanno poi sfruttata in maniera intensiva. Intorno al 1150 a.C., vale a dire dopo cinque secoli di vita, questa cultura ha vissuto un crollo generalizzato. Lo studio delle modalit� di occupazione di questo territorio ha come fine ultimo quello di comprendere meglio tali aspetti peculiari. Questo lavoro ha dimostrato, grazie alla ricostruzione del sistema idrico del Et� del Bronzo, l'esistenza di stretti legami tra terramare e corsi d'acqua, tra cui anche la deviazione del flusso nei fossati periferici ai siti. Tali attivit� sono probabilmente correlate con lo sviluppo di sistemi d?irrigazione e di drenaggio. � stato possibile formulare alcune ipotesi circa lo stato di attivazione di dossi alluvionali relativamente al periodo in questione. Le analisi spaziale hanno evidenziato l'esistenza di assi di circulazione e di scambio sia fluviali che terrestri. Questi ultimi interessano i tre territori individuati. Questi aspetti hanno permesso di avanzare delle proposte di organizzazione sociale e di apportare dei chiarimenti riguardo a certe pratiche rituali e votive, sebbene in un contesto povero di questo tipo di dati. Infine, � stato possibile relativizzare la rapidit� dei processi di genesi e di declino della cultura analizzata.

description: The hidden symmetry and an infinite set non-local conserved currents of the Green-Schwarz superstring on $AdS_5\otimes S^5$ have been pointed out by Bena et al. In this paper, we shown that the Hodge dual between the Maurer-Cartan equation and the equation of motion gives the hidden symmetry in the moduli space of Green-Schwarz superstring. Thus by twisty transforming the vielbeins, we can express the currents of the paper$^{\cite{bpr}}$ as the Lax connections by a unique spectral parameter.

description: We construct analytic solutions of open superstring field theory for any exactly marginal deformation in any boundary superconformal field theory when properly renormalized operator products of the marginal operator are given. Our construction is an extension of the general framework for marginal deformations developed in arXiv:0707.4472 for open bosonic string field theory, and the solutions are based on integrated vertex operators which are closely related to finite deformations in boundary superconformal field theory.

description: Leptohyphodes inanis (Pictet) is an enigmatic species with a rare trait among leptohyphid males – large and divided compound eyes. In addition, the color of its upper portion is variable across – but not within – populations. However, the geographic variation of this trait and its relation to gene flow across populations remain unknown. Here, we analyzed individuals across Southeastern Brazil (19º to 24ºS and 40º to 48º W) to (i) assess genetic (COI) and eye color variation, and (ii) evaluate if L. inanis is a single species, by combining Bayesian phylogenetic analyses (including two other leptohyphid genera – Tricorythopsis and Tricorythodes) and species delimitation methods: ABGD and mPTP. To further investigate within-species variation in phenotypic traits, we evaluated quantitative and qualitative morphological traits of 1,252 individuals. We found that genetic variation in L. inanis is largely unrelated to eye color, and that pairwise genetic divergences in COI mtDNA are remarkably higher (up to 30.7%) than previously found in other mayfly lineages. L. inanis was recovered as monophyletic, although results suggest it includes three to seven cryptic species, each one related to mountain ranges across Southeastern Brazil. Furthermore, we found no genetic variation among individuals of the same drainage basin, suggesting that populations might be largely isolated from one another. Because morphological traits traditionally used in Ephemeroptera taxonomy were ineffective in distinguishing the cryptic species, we propose L. inanis to be a species complex.

description: We discuss generic properties of rotating nonlinear wave solutions, the so called azimuthons, in nonlocal media. Variational methods allow us to derive approximative values for the rotating frequency, which is shown to depend crucially on the nonlocal response function. Further on, we link families of azimuthons to internal modes of classical non-rotating stationary solutions, namely vortex and multipole solitons. This offers an exhaustive method to identify azimuthons in a given nonlocal medium.

description: Using a conventional Hall-bar geometry with a micro-metal strip on top of the surface, we demonstrate an electrical coherent control of nuclear spins in an AlGaAs/GaAs semiconductor heterostructure. A breakdown of integer quantum Hall (QH) effect is utilized to dynamically polarize nuclear spins. By applying a pulse rf magnetic field with the metal strip, the quantum state of the nuclear spins shows Rabi oscillations, which is detected by measuring longitudinal voltage of the QH conductor.

PV Module Design, Manufacture, Performance and Reliability

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 909-915
description: Besides common installation of PV systems, more technical complex applications such as vehicle integrated PV modules or Energy Parks (combined solar and wind farms) gain significant market attraction. One of challenges for such applications is fast periodic shadings by obstacles or wind blades. This paper investigates an approach to integrate passive elements in parallel to each individual cell of the module and compares the performance of a standard PV module with a module with integrated capacitors as passive elements and a PV module with bypass diodes for every single cell under fast periodic shading conditions. For this purpose, in the first step, the module is simulated under different moving shading conditions. In the next step a PV module with open terminals for every solar cell is fabricated and measured outdoor as reference module with no attached elements and with bypass diodes or capacitors for cells under partial shading conditions. The results show that modules with additional capacitors or diodes in module level can benefit higher energy yield compared to standard PV modules. The energy performance of a capacitor integrated module is mainly dependent by the shading transient, due to the time dependent compensating currents of the capacitors. This paper proves the concept of functionality of capacitor for compensation of power loss under shading conditions but the feasibility of integration is a challenge. However, the results show a better performance of the module with bypass diodes compared to the capacitor integrated module with 44 mF capacity.
On the Conditions for Neutron-Rich Gamma-Ray Burst Outflows

description: We calculate the structure and neutron content of neutrino-heated MHD winds driven from the surface of newly-formed magnetars (``proto-magnetars'') and from the midplane of hyper-accreting disks, two of the possible central engines for gamma-ray bursts (GRBs) and hyper-energetic supernovae (SNe). Both the surface of proto-magnetars and the midplane of neutrino-cooled accretion flows (NDAFs) are electron degenerate and neutron-rich (neutron-to-proton ratio n/p >> 1). If this substantial free neutron excess is preserved to large radii in ultra-relativistic outflows, several important observational consequences may result. Weak interaction processes, however, can drive n/p to ~1 in the nondegenerate regions that obtain just above the surfaces of NDAFs and proto-magnetars. Our calculations show that mildly relativistic neutron-rich outflows from NDAFs are possible in the presence of a strong poloidal magnetic field. However, we find that neutron-rich winds possess a minimum mass-loss rate that likely precludes simultaneously neutron-rich and ultra-relativistic (Lorentz factor > 100) NDAF winds accompanying a substantial accretion power. In contrast, proto-magnetars are capable of producing neutron-rich long-duration GRB outflows ~10-30 seconds following core bounce for sub-millisecond rotation periods; such outflows would, however, accompany only extremely energetic events, in which the GRB + SN energy budget exceeds ~ 4e52 ergs. Neutron-rich highly relativistic outflows may also be produced during some short-duration GRBs by geometrically thick accretion disks formed from compact object mergers. The implications for r-process nucleosynthesis, optical transients due to non-relativistic neutron-rich winds, and Nickel production in proto-magnetar and NDAF winds are also briefly discussed.

description: This paper aimed to test the prediction that substantial undiscovered biodiversity in the tapeworm genus Yamaguticestus Caira, Bueno & Jensen, 2021 exists in the 16 of 18 genera of catsharks globally that have not yet been examined for tapeworms. A total of 200 catsharks of 10 species representing eight genera were sampled opportunistically from the waters off Australia, Chile, Malaysian Borneo, South Africa, South Korea, and the UK between 1991 and 2017. Six species in four genera (i.e., Apristurus Garman, Asymbolus Whitley, Holohalaelurus Fowler, and Scyliorhinus Blainville) were found to host a total of six new species of Yamaguticestus, tripling the number of described species. The new species are Yamaguticestus africanae sp. nov. from Scyliorhinus capensis, Yamaguticestus ellisi sp. nov. from Scyliorhinus canicula, Scyliorhinus fairweatherae sp. nov. from Holohalaelurus regani, Yamaguticestus kihongkimi sp. nov. from Scyliorhinus torazame, and Yamaguticestus kuchtai sp. nov. from Apristurus aphyodes. The new species were characterized using a combination of light and scanning electron microscopy; sequence data for the D1–D3 region of the 28S rRNA gene were generated for five of the species. Transfer of a species formerly assigned to Calyptrobothrium Monticelli, 1893 that is morphologically consistent with Yamaguticestus added Cephaloscyllium Gill to the list of catshark genera known to host this genus. Most tapeworm species exhibited a remarkably low prevalence and intensity of infection suggesting that our failure to detect infection in the four genera of sharks represented by small sample sizes may not be indicative of their unsuitability as hosts. Our results suggest that the earlier prediction that 70 species of Yamaguticestus remain to be discovered in catsharks across the planet may actually be an underestimate. http://zoobank.org/urn:lsid:zoobank.org:pub:63F48CF6-ED06-44FC-839D-

description: One of the most important issues that reduces the performance of photovoltaic (PV) modules which is due to irradiance degradation caused by dust deposition on the top surface of PV modules. It is a well-known fact that this phenomenon would decrease irradiance and the question of how much loss would happen due to dust has been a major subject among researchers. This study was conducted to determine the soiling loss for photovoltaic modules installed in Shiraz, Iran. For measurement, a set of PV modules installed with a tilt angle of 30° and short-circuited current of each module, wind speed, ambient humidity, ambient temperature, module temperature as well as solar radiation are measured continuously during the period of experiment. Results from the measurement field indicate that average daily soiling loss for eight weeks of exposure which is started since 11 December 2016 is – 4.45 %.
