description: Visual observations of dynamic phenomena, such as human actions, are often represented as sequences of smoothly-varying features . In cases where the feature spaces can be structured as Riemannian manifolds, the corresponding representations become trajectories on manifolds. Analysis of these trajectories is challenging due to non-linearity of underlying spaces and high-dimensionality of trajectories. In vision problems, given the nature of physical systems involved, these phenomena are better characterized on a low-dimensional manifold compared to the space of Riemannian trajectories. For instance, if one does not impose physical constraints of the human body, in data involving human action analysis, the resulting representation space will have highly redundant features. Learning an effective, low-dimensional embedding for action representations will have a huge impact in the areas of search and retrieval, visualization, learning, and recognition. The difficulty lies in inherent non-linearity of the domain and temporal variability of actions that can distort any traditional metric between trajectories. To overcome these issues, we use the framework based on transported square-root velocity fields (TSRVF); this framework has several desirable properties, including a rate-invariant metric and vector space representations. We propose to learn an embedding such that each action trajectory is mapped to a single point in a low-dimensional Euclidean space, and the trajectories that differ only in temporal rates map to the same point. We utilize the TSRVF representation, and accompanying statistical summaries of Riemannian trajectories, to extend existing coding methods such as PCA, KSVD and Label Consistent KSVD to Riemannian trajectories or more generally to Riemannian functions.

description: The purpose of this report is to describe the motivation and set up of the International Secure Data
 Facility Professionals Network (ISDFPN), its aims, first steps, and future plans.
 ISDFPN has been set up as part of the Social Sciences and Humanities Open Cloud project (SSHOC) Task
 5.4 with the aim of bringing together international colleagues working in or towards Secure Data
 Facilities, to share expertise and experiences, discuss relevant areas of our work, and to spark
 collaboration as well as develop new ideas.
 Whereas various international networks and collaborations exist, which aim to improve the
 international data infrastructure and landscape, and establish connections between Secure Settings,
 there is also a Forum needed for professional staff working in these Secure Data Facilities
 1
 , which
 provides a platform for and facilitates regular knowledge exchange. ISDFPN is not a Network to
 establish remote connections between Secure Data Facilities but a Forum to share experience,
 expertise, and ideas, which is not available (yet) formally somewhere else. As the fast-changing secure
 data landscape evolves, this Network has been designed to be a vital resource for collaborative work
 towards solutions for shared as well as newly emerging problems staff faces when working in Secure
 Data Facilities. Nationally as well as internationally, these Secure Data Facilities are at different stages in
 their development, which makes such a Network a good Forum for learning from one another.
 The International Secure Data Facility Network held its first online meeting on 30 March 2022,
 introducing the Network and its aims and objectives, discussing possible topics of interest for the
 Network, and establishing whether the invited parties have an interest in joining this Network. Further,
 a first topical session on Secure Data Facility staff skills and training needs was run, and a plan agreed
 for its first year 2022/2023.
 Even though SSHOC finishes at the end of April 2022, this Network will be taken forward in joint
 collaboration between the UK Data Service and GESIS Leibniz Institute for the Social Sciences. So far, it
 has 22 members from 13 different institutions. The next meeting will take place on 7 September 2022.

description: In this paper a compact charged stellar model in the Finch and Skea background spacetime [{\it Class. Quantum Gravity} {\bf6}, 467 (1989)] is presented. The model has been developed by assuming a particular charge distribution within the stellar interior. The model is well behaved and can describe a large class of compact stars. Physical features of the model are studied and in particular we show how the presence of charge can have a non-negligible impact on the mass-radius ($M-R$) relationship of such class of stars.

PV Module Design, Manufacture, Performance and Reliability

description: 37th European Photovoltaic Solar Energy Conference and Exhibition; 828-833
description: For photovoltaics (PV) to be cost competitive with traditional energy sources, reliability is of critical importance. Historically, PV reliability has focused on the module packaging because degradation and failure modes were directly linked to the packaging. Today, in addition to module packaging, cell related reliability issues can increasingly be observed. We have investigated PV systems of high-efficiency modules such as silicon heterojunction (HJ) and passivated emitter and rear cell (PERC). System degradation of these technologies is found to be no worse than systems using conventional cell technologies. Module performance loss, for HJ and PERC technologies, shows open-circuit voltage reduction indicative of cell level changes. For HJ modules, possible hydrogen concentration changes and a rougher interface between the amorphous silicon and the silicon is observed, although more samples are needed to confirm these findings. The PERC modules show hydrogen changes in the front and rear of the cell with more changes pronounced at the front. Importantly, these two case studies demonstrate that cell level understanding is required to accurately predict module and system performance for high-efficiency technologies.

PV Module Design, Manufacture, Performance and Reliability

description: 37th European Photovoltaic Solar Energy Conference and Exhibition; 811-815
description: The IEC 61853 standard series “Photovoltaic (PV) module performance testing and energy rating” aims to provide a standardized measure for PV module performance, namely the Climate Specific Energy Rating (CSER). An algorithm to calculate CSER is specified in part 3 based on laboratory measurements defined in parts 1 and 2 as well as the climate data set given in part 4. To test the comparability and clarity of the algorithm in part 3, we share the same input data, obtained by measuring a standard photovoltaic module, among different research organizations. Each participant then uses their individual implementations of the algorithm to calculate the resulting CSER values. The initial blind comparison reveals differences of 0.133 (14.7%) in CSER between the ten different implementations of the algorithm. Despite the differences in CSER, an analysis of intermediate results revealed differences of less than 1% at each step of the calculation chain among at least three participants. Thereby, we identify the extrapolation of the power table, the handling of the differences in the wavelength bands between measurement and climate data set, and several coding errors as the three biggest sources for the differences. After discussing the results and comparing different approaches, all participants rework their implementations individually and compare the results two more times. In the third intercomparison, the differences are less than 0.029 (3.2%) in CSER. When excluding the remaining three outliers, the largest absolute difference between the other seven participants is 0.0037 (0.38%). Based on our findings we identified four recommendations for improvement of the standard series.

description: 37th European Photovoltaic Solar Energy Conference and Exhibition; 816-821
description: The aim of this work was to re-evaluate the methodology for Climate Specific Energy Rating (CSER), as defined in the IEC 61853 standard series “Photovoltaic (PV) module performance testing and energy rating”, in view of spectral related uncertainties. Our research covered two aspects: (a) IEC 61853 assumes a fixed spectral response curve of the PV device and does not consider its temperature dependence. (b) CSER calculation uses tabulated lowresolution spectral irradiance data (29 data points) for spectral mismatch calculation whereas real solar spectra result from high-resolution measurement. To quantify uncertainties for CSER caused by these effects, we used historical data from our PV energy yield test sites in Cologne (Germany) and Tempe (Arizona, USA) that include both a highresolution spectral irradiance measurement and temperature measurements of various PV module technologies. PV module spectral response curves at variable temperatures resulted from laboratory measurements. We introduced the annual irradiance-weighted spectral mismatch as an indicator for spectral impacts on CSER and compared the current IEC 61853 methodology (baseline) with a methodology that considers the above mentioned temperature and spectral irradiance aspects. Our results show that the current CSER methodology is insensitive to temperature effects (uncertainty < ±0.05%). However, the transition from high-resolution spectra to low-resolution Kato-band spectra can cause systematic errors in CSER. While there are only small impacts for CdTe (-0.1%) and CIGS (-0.3%) the transition to low-resolution Kato-bands leads to systematic CSER errors up to -0.9% for c-Si PV technologies. These systematic CSER errors are significantly reduced by adjustment of the wavelength intervals of low-resolution spectra. We propose these “PV-bands” to introduce in the CSER methodology.

description: We investigate statistics of lead changes of the maxima of two discrete-time random walks in one dimension. We show that the average number of lead changes grows as $π^{-1}\ln(t)$ in the long-time limit. We present theoretical and numerical evidence that this asymptotic behavior is universal. Specifically, this behavior is independent of the jump distribution: the same asymptotic underlies standard Brownian motion and symmetric Levy flights. We also show that the probability to have at most n lead changes behaves as $t^{-1/4}[\ln t]^n$ for Brownian motion and as $t^{-β(μ)}[\ln t]^n$ for symmetric Levy flights with index $μ$. The decay exponent $β(μ)$ varies continuously with the Levy index when $02$.

description: Photovoltaic (PV) panels in large arrays operate at high voltages and, as a result, can experience potentialinduced degradation (PID). At these high voltages, leakage currents drive sodium out of the glass at the front of the panels, through the polymer encapsulant, and into the sensitive electronics at the core. Initial work by other groups has suggested that changing the polymeric encapsulant layer could limit sodium migration. However, the polymer characteristics and mechanisms that moderate sodium migration are not yet understood. In this work the role of panel encapsulants in PV panel PID is being investigated. Glass/encapsulant coupons will be exposed to high voltages to evaluate degradation. Several coupons contain PV cells that will be periodically monitored via current versus voltage measurements and electroluminescence imaging to track performance degradation. Coupon samples without cells will be cut to expose cross sections for materials characterization. Crosssectional analysis, using energy dispersive spectroscopy, will quantify the amount of sodium that has moved through different encapsulant polymers (ethylene-vinyl acetate, polyolefin, and ionomer). In tandem, the chemistry and structure of the polymers will be characterized to develop an understanding of which polymer characteristics limit sodium movement. An understanding of how polymer encapsulants can limit sodium migration will inform the development of next generation polymers. Improved polymer encapsulants that limit sodium migration will significantly increase the service lifetime of PV panels.

description: Non-radial pulsations have been identified in a number of accreting white dwarfs in cataclysmic variables. These stars offer insight into the excitation of pulsation modes in atmospheres with mixed compositions of hydrogen, helium, and metals, and the response of these modes to changes in the white dwarf temperature. Among all pulsating cataclysmic variable white dwarfs, GW Librae stands out by having a well-established observational record of three independent pulsation modes that disappeared when the white dwarf temperature rose dramatically following its 2007 accretion outburst. Our analysis of HST ultraviolet spectroscopy taken in 2002, 2010 and 2011, showed that pulsations produce variations in the white dwarf effective temperature as predicted by theory. Additionally in May~2013, we obtained new HST/COS ultraviolet observations that displayed unexpected behaviour: besides showing variability at ~275s, which is close to the post-outburst pulsations detected with HST in 2010 and 2011, the white dwarf exhibits high-amplitude variability on a ~4.4h time-scale. We demonstrate that this variability is produced by an increase of the temperature of a region on white dwarf covering up to ~30 per cent of the visible white dwarf surface. We argue against a short-lived accretion episode as the explanation of such heating, and discuss this event in the context of non-radial pulsations on a rapidly rotating star

description: The investigation of VHE gamma-ray sources by any methods, including mirror Cherenkov telescopes, touches on the problem of the cosmic ray origin and, accordingly, the role of the Galaxy in their generation. The SHALON observations have yielded the results on Galactic shell-type supernova remnants (SNR) on different evolution stages. Among them are: SNRs Tycho's SNR, Cas A, IC 443, $γ$Cygni SNR and classical nova GK Per (Nova 1901). For each of SNRs the observation results are presented with spectral energy distribution by SHALON in comparison with other experiment data and images by SHALON. The collected experimental data have confirmed the prediction of the theory about the hadronic generation mechanism of very high energy 800 GeV - 100 TeV $γ$-rays in Tycho's SNR, Cas A and IC443.

description: While the term “potential induced degradation” (PID) has been recognized to encompass multiple mechanisms by which photovoltaic device performance is reduced as a result of exposure to voltage stress, the critical factors that influence these mechanisms are not well understood. While certain encapsulating materials have been observed to mitigate or prevent PID of the shunting type (PID-s) or of the polarization type (PID-p), different material properties may in fact be responsible in each case. Additionally, light exposure during voltage stress has been observed to prevent PID in some cases but not in others. In this work, the influence of both encapsulating material as well as light exposure upon PID-p susceptible p+/n faces of n-PERT cells is explored, revealing the critical role of encapsulant resistivity in reducing the rate of power loss. In such cell type, we find that both illumination and high resistivity encapsulant contribute to the mitigation of PID-p.

description: We report 29Si nuclear magnetic resonance measurements of single crystals and aligned powders of URu2Si2 under pressure in the hidden order and paramagnetic phases. We find that the Knight shift decreases with applied pressure, consistent with previous measurements of the static magnetic susceptibility. Previous measurements of the spin lattice relaxation time revealed a partial suppression of the density of states below 30 K. This suppression persists under pressure, and the onset temperature is mildly enhanced.

description: The authors report on the Light and elevated Temperature Induced Degradation effect (LeTID) observed on bifacial photovoltaic modules and its potential impact on photovoltaic plants performance. Indoor LeTID quantification using indoor Carrier Induced Degradation (CID) is carried out using current injection. Power measurements yielded higher LeTID sensitivity for the rear side of bifacial modules compared to the front side hence leading to a variation of the bifaciality factor by several percentage points. The difficulty in evaluating the maximal power degradation caused by LeTID is also highlighted as a reduced number of samples is used most of the time and as cells within a single module don’t have always the same performance evolution trends. Using indoor CID results with the help of empirical fitting and Arrhenius relation, the yield impact of LeTID on a bifacial power plant is simulated under three different climates. Modelling results help to identify the main parameters related to LeTID modules sensitivity that impact PV plants yield: maximal power degradation, stabilized power value after regen-eration, activation energy value and LeTID kinetics. In some cases, the yield variation caused by LeTID sensitive modules could be mitigated by carefully selecting the modules as a function of climatic conditions.

description: Recent studies showed that silicon heterojunction (SHJ) solar cells can be prone to potential induced degradation (PID) when encapsulated with a low volume resistivity ethylene vinyl acetate (EVA). We perform PID test in humid conditions (85°C/85% RH) on glass/glass one-cell modules with and without an edge sealant, to ensure an uniformly applied potential all over the module surface. We also analyze the effect of moisture ingress by using these module structures. We demonstrate that with the proper module packaging (i.e. a glass/glass structure with edge sealant), EVA can be used as an encapsulant material for SHJ solar cells. PID can be completely prevented even when subjected to extended tests (e.g. eight times the 96 h of test duration foreseen in the IEC Technical Specification for c-Si modules). On the other hand, SHJ modules packaged in a glass/glass structure using EVA (and no edge seal) start exhibiting a degradation in performance after 192 h of PID test (i.e. twice the test duration foreseen by IEC TS 62804-1). The degradation becomes considerable after 800 h of test, driven by a reduction in shortcircuit current (JSC), fill factor (FF) and open-circuit voltage (VOC).

We provide extended and robust measurements of the stellar population parameters in NGC 3311, the cD galaxy at the centre of the Hydra I cluster and out to three effective radii. Using seven absorption-features defined in the Lick/IDS system and single stellar populations models, we obtained luminosity-weighted ages, metallicities and alpha element abundances. The trends in the Lick indices and the distribution of the stellar population parameters indicate that the stars of NGC 3311 may be divided into two radial regimes, one within and the another beyond one effective radius, $R_e = 8.4$ kpc, similar to the distinction between inner galaxy and external halo derived from the NGC 3311 velocity dispersion profile. The inner galaxy ($R\leq R_e$) is old (age $\sim 14$ Gyr), have negative metallicity gradients and positive alpha element gradients. The external halo is also very old, but the metal and element abundances of the external halo have both a large scatter, indicating that stars from a variety of satellites with different masses have been accreted. The region in the extended halo associated with the off-centred envelope at 0$^o$ < P.A.< 90$^o$ (Arnaboldi et al. 2012) has higher metallicity with respect to the symmetric external halo. The different stellar populations in the inner galaxy and extended halo reflect the dominance of in situ stars in the former and the accreted origin for the large majority of the stars in the latter. These results provide supporting evidence to the recent theoretical models of formation of massive ellipticals as a two-phase process.

PV Module Design, Manufacture, Performance and Reliability

description: 37th European Photovoltaic Solar Energy Conference and Exhibition; 792-795
description: The recent trend to increase the PV system voltage from 1000 V to 1500 V implies a higher PID stress level for the PV modules. This raises the question whether the modules might face PID problems caused by 1500 V system voltage during long-term field operation. Particularly, the IEC TS 62804-1 PID test does not provide a correlation between accelerated chamber testing and outdoor field operation. In this work, we follow the principle established for thin film modules according to the IEC TS 62804-2, where the transferred charge is the metric for the PID stress load. Furthermore, in order to transfer charge as fast as possible during lab testing, extreme PID testing conditions were applied. Test modules were manufactured combining two types of c-Si cells, “more PID stable” and “less PID stable”, with three types of encapsulation material, EVA1, EVA-2, and POE respectively. Surprisingly the IEC standard test could not differentiate the PID susceptibilities of the test modules. Even prolonged testing did not provoke a further degradation. Dropping leakage currents due to a blocking anode effect are suspected as the root cause for the observed, but misleading PID stability. In contrast to this, a clear differentiation of the module´s PID susceptibility was possible with our extreme test conditions. The transferred Coulombs under real outdoor conditions were measured at the ZSW test field for a whole year. With this information, the PID service life could be predicted. Modules based on POE are predicted to stay free from PID during a service life of 40 years.

description: We propose that chondrules are formed by radiative heating of pre-existing dust clumps during close fly-bys of planetesimals with incandescent lava at their surfaces. We show that the required temperatures and cooling rates are easily achieved in this scenario and discuss how it is consistent with bulk aspects of chondritic meteorites, including complementarity and the co-mingling of FeO-poor and FeO-rich chondrules.

description: Galaxy clusters are the most recent, gravitationally-bound products of the hierarchical mass accretion over cosmological scales. How the mass is concentrated is predicted to correlate with the total mass in the cluster's halo, with systems at higher mass being less concentrated at given redshift and for any given mass, systems with lower concentration are found at higher redshifts. Through a spatial and spectral X-ray analysis, we reconstruct the total mass profile of 47 galaxy clusters observed with Chandra in the redshift range $0.40.4$, and is well suited to provide the first constraint on the concentration--mass relation at $z>0.7$ from X-ray analysis. Under the assumptions that the distribution of the X-ray emitting gas is spherically symmetric and in hydrostatic equilibrium, we combine the deprojected gas density and spectral temperature profiles through the hydrostatic equilibrium equation to recover the parameters that describe a NFW total mass distribution. The comparison with results from weak lensing analysis reveals a very good agreement both for masses and concentrations. Uncertainties are however too large to make any robust conclusion on the hydrostatic bias of these systems. The relation is well described by the form $c \propto M^B (1+z)^C$, with $B=-0.50 \pm 0.20$, $C=0.12 \pm 0.61$ (at 68.3\% confidence), it is slightly steeper than the one predicted by numerical simulations ($B\sim-0.1$) and does not show any evident redshift evolution. We obtain the first constraints on the properties of the concentration--mass relation at $z > 0.7$ from X-ray data, showing a reasonable good agreement with recent numerical predictions.

description: The proton-rich nucleus $^{23}$Al has a ground state just 123 keV below the proton drip-line, and as a result comparatively little is known experimentally about its properties, as with many such nuclei. Theoretical investigations have tended to model exclusively the ground and first one to three excited states known. In this paper, we theoretically model most of the known spectrum, and predict what states may as yet be unobserved. We use the multichannel algebraic scattering (MCAS) method to describe states as resonances of a valence proton coupled to a $^{22}$Mg rotor core. Six states with low-excitation energies and defined $J^π$ are matched, and we make the first prediction of the properties of four others and propound the possible existence of several more.

description: The inverse scattering problem on the half-line has been studied in the literature in detail. V. Marchenko presented the solution to this problem. In this paper, the invertibility of the steps of the inversion procedure is discussed and a new set of necessary and sufficient conditions on the scattering data is given for the scattering data to be generated by a potential suitable potential. Our proof is new and in contrast with known proof it does not use equations on the negative half-line.

description: We introduce a simple model to describe the interplay between specific and non-specific interactions. We study the influence of various physical factors on the static and dynamic properties of the specific interactions of our model and show that contrary to intuitive expectations, non-specific interactions can assist in the formation of specific complexes and increase their stability. We then discuss the relevance of these results for biological systems.

description: Presentation of the probability as an intrinsic property of the nature leads researchers to switch from deterministic to stochastic description of the phenomena. The procedure of stochastization of one-step process was formulated. It allows to write down the master equation based on the type of of the kinetic equations and assumptions about the nature of the process. The kinetics of the interaction has recently attracted attention because it often occurs in the physical, chemical, technical, biological, environmental, economic, and sociological systems. However, there are no general methods for the direct study of this equation. Leaving in the expansion terms up to the second order we can get the Fokker-Planck equation, and thus the Langevin equation. It should be clearly understood that these equations are approximate recording of the master equation. However, this does not eliminate the need for the study of the master equation. Moreover, the power series produced during the master equation decomposition may be divergent (for example, in spatial models). This makes it impossible to apply the classical perturbation theory. It is proposed to use quantum field perturbation theory for the statistical systems (the so-called Doi method). This work is a methodological material that describes the principles of master equation solution based on quantum field perturbation theory methods. The characteristic property of the work is that it is intelligible for non-specialists in quantum field theory. As an example the Verhulst model is used because of its simplicity and clarity (the first order equation is independent of the spatial variables, however, contains non-linearity). We show the full equivalence of the operator and combinatorial methods of obtaining and study of the one-step process master equation.

description: In this article, we study the continuous and discrete fractional persistence problem which looks for the persistence of properties of a given classical ($α=1$) differential equation in the fractional case (here using fractional Caputo's derivatives) and the numerical scheme which are associated (here with discrete Grünwald-Letnikov derivatives). Our main concerns are positivity, order preserving ,equilibrium points and stability of these points. We formulate explicit conditions under which a fractional system preserves positivity. We deduce also sufficient conditions to ensure order preserving. We deduce from these results a fractional persistence theorem which ensures that positivity, order preserving, equilibrium points and stability is preserved under a Caputo fractional embedding of a given differential equation. At the discrete level, the problem is more complicated. Following a strategy initiated by R. Mickens dealing with non local approximations, we define a non standard finite difference scheme for fractional differential equations based on discrete Grünwald-Letnikov derivatives, which preserves positivity unconditionally on the discretization increment. We deduce a discrete version of the fractional persistence theorem for what concerns positivity and equilibrium points. We then apply our results to study a fractional prey-predator model introduced by Javidi and al.

PV Module Design, Manufacture, Performance and Reliability

description: 37th European Photovoltaic Solar Energy Conference and Exhibition; 777-783
description: The aim of this work is to propose a BIPV module design that is contemporarily lightweight, rigid and resistant to the relevant climatic and mechanical stresses (e.g. exposure to DH, UV, hail impacts, etc), supporting structure and reliability at the same time. Encapsulants represent a key part in the PV structure, acting as the bonding layer between the front or back sheet and the PV cell. Therefore, they need to provide excellent adhesion between these components, which is achieved via lamination. They also have to be transparent and provide outstanding electrical insulation and impact resistance to the module. All these properties must be retained after years of exposure to the UV from the sun or other severe weather conditions. With this work, we want to provide a “recipe” to define and qualify the optimum front sheet encapsulant for the proposed lightweight composite PV modules.

description: Double glass PV modules are expected to be more durable on the long term with respect to modules in a conventional glass/back-sheet configuration. The combination of a rear and front glass cover can in fact delay or completely prevent moisture ingress into the module structure. However, water can be absorbed from the environment by the virgin encapsulant so that storage conditions can be relevant in ensuring the long-time performance of the encapsulant and the PV module. Additionally, in a glass/glass configuration products formed during the aging of the polymeric encapsulant will remain trapped inside the module, affecting the long-term performance of the module. The encapsulant choice is then an important aspect to consider for the encapsulation scheme of bifacial modules. In this work, we investigate the effect of non-optimal storage conditions of EVA and its impact on long-term UV aging. After a total UV dose of 165 kWh/m2 (corresponding to an outdoor exposure of ~2.2 years in a temperate climate the performance of 1-cell mini-modules does not vary. However, preliminary signs of chemical degradation are detectable by means of Raman and FTIR spectroscopy for the non-properly-stored polymer , suggesting that carefully controlling the storage conditions of the polymer may be critical if EVA is used in double glass structures.
