description: The scalar sector of the minimal Left-Right model at TeV scale is revisited in light of the large quartic coupling needed for a heavy flavor-changing scalar. The stability and perturbativity of the effective potential is discussed and merged with constraints from low-energy processes. Thus the perturbative level of the Left-Right scale is sharpened. Lower limits on the triplet scalars are also derived: the left-handed triplet is bounded by oblique parameters, while the doubly-charged right-handed component is limited by the $h \to γγ, Z γ$ decays. Current constraints disfavor their detection as long as $W_R$ is within the reach of the LHC.

description: The examination of PV module performance in the outdoor has been carried out by system loss analysis methodology with utilizing set-up of the soiling monitoring platform-Dust Detection System (DDS).The platform equips with two identical PV modules in which power outputs are tracked simultaneously with one PV module surface always maintained clean and the performance difference may represent soiling impact on the PV module in the test field. Since 2013 and 2014, two DDS have been installed respectively in Jordan and Saudi Arabia to study long-term PV module performance in Middle East area. Module loss examination through proposed analysis methodology has successfully indicated the performance difference from the rated power on the nameplate from corresponding manufacturers, which can offer a systematic overview to power loss in the outdoor testing.

description: In this paper, we evaluate, up to QCD next-to-next-to-next-to-leading order, the $B_c^*$ decay constant, which, within the nonrelativistic QCD (NRQCD) framework, is factorized as the product of the short-distance coefficient (SDC) and the long-distance matrix element. For the first time, the renormalization constant and the anomalous dimension for the NRQCD vector current composed of $c\bar{b}$, which are functions of the charm quark mass $m_c$, the bottom quark mass $m_b$ and the factorization scale $μ_Λ$, are obtained analytically at $\mathcal{O}(α_s^2)$ and $\mathcal{O}(α_s^3)$. The SDC is calculated up to $\mathcal{O}(α_s^3)$ in perturbative expansion. Explicitly, the $\mathcal{O}(α_s^2)$ correction to the SDC is analytically calculated in terms of logarithmic and polylogarithmic functions of $r\equiv m_b/m_c$, and the $\mathcal{O}(α_s^3)$ correction to the SDC is numerically calculated at a series of values of $r$, ranging from $2.1$ to $4.0$. Surprisingly, we find that the nontrivial part of the SDC at $\mathcal{O}(α_s^3)$ can be well estimated by a linear function of $r$. In addition, We find that the $\mathcal{O}(α_s^2)$ and $\mathcal{O}(α_s^3)$ corrections to the decay constant and decay width are considerable and very significant, which indicates a very poor convergence for the perturbative expansion.

description: Brazil is seen as a potential GW-scale photovoltaic (PV) market of the future. It possesses extensive land area (~8.5 million km2), excellent solar resource (annual irradiation values ranging from ~1,500 to ~2,200 kWh/m2), relatively high electricity tariffs and a booming economy, all ingredients which put the country on the path of massive PV energy implementation. This work presents a review of the previously installed grid-connected PV capacity up to 2013. The performance of some of the PV systems already connected to the grid is presented for ten sites. Performance metrics “specific energy yield” [kWh/kWp] as well as “performance ratio”, PR [%] are used, with both locally measured solar irradiation as well as other available databases working as a benchmark to the current system knowledge-base in the country.

description: This paper evaluates the importance of “solar radiation incidence angle” effect on photovoltaic modules performance in Mediterranean sites and calculates theoretically the best tilt angle, for minimum angle of incidence. The data has been taken using a photovoltaic system installed in tilt on the roof of the building of Electrical and Computer Engineer’s department at the University of Patras Greece (latitude 380). The investigation is done through a systematic analysis of the variation of maximum power delivered in different conditions and a theoretical model applied for this purpose. The paper presents results using monocrystalline silicon photovoltaic modules in outdoors conditions.

description: The aim of this paper was to present a specific quality program for optimisation a huge set of already well performing PV power plants. In order to find relevance factors on performance of multi MW solar plants, a smart set of well-known tools was combined with new developed software considering techniques for easy handling of huge monitoring data within two years. Additionally clear management structure have shown an unexpected high improvement of plant performance as result from early recognizing of faults and further risk minimizing of technical failures. In this study, examples of the enhancement process the simulation and experimental results of different partial shading effect of PV modules and their impact on total system performance are discussed. Furthermore, this paper provides useful methodology for easy characterisation of inverter efficiency and early identification of improvement possibilities and a short description of the process structure to realize the single tasks.

description: Photovoltaic (PV) ground faults have caused many fires in the U.S. and around the world. Recently, the American PV industry has discovered a blind spot in fuse-based ground fault detection that has spurred a transition to a number of alternatives traditionally used in European markets. This paper investigates the repeatability of one of these methods, residual current detection (RCD), using historical field data from 340 utility-scale inverters in a large 170 MW installation. The distributions of leakage current magnitudes for the inverters is calculated for one year to determine a statistical RCD trip metric that minimizes unwanted tripping but increases the sensitivity of ground fault detection. The RCD current transients were also studied to determine the efficacy using the derivative of RCD current to detect high impedance ground faults.

description: Measurements of the luminosity of type Ia supernovae vs. redshift provided the original evidence for the accelerating expansion of the Universe and the existence of dark energy. Despite substantial improvements in survey methodology, systematic uncertainty in flux calibration dominates the error budget for this technique, exceeding both statistics and other systematic uncertainties. Consequently, any further collection of type Ia supernova data will fail to refine the constraints on the nature of dark energy unless we also improve the state of the art in astronomical flux calibration to the order of 1%. We describe how these systematic errors arise from calibration of instrumental sensitivity, atmospheric transmission, and Galactic extinction, and discuss ongoing efforts to meet the 1% precision challenge using white dwarf stars as celestial standards, exquisitely calibrated detectors as fundamental metrologic standards, and real-time atmospheric monitoring.

description: Urinary bladder cancer, a smoking and occupation related disease, was subject of several genome-wide association studies (GWAS). However, studies on the course of the disease based on GWAS findings differentiating between muscle invasive bladder cancer (MIBC) and non-muscle invasive bladder cancer (NMIBC) are rare. Thus we investigated 4 single nucleotide polymorphisms (SNPs) detected in GWAS, related to the genes coding for TACC3 (transforming, acidic coiled-coil containing protein 3), for FGFR3 (fibroblast growth factor receptor 3), for PSCA (prostate stem cell antigen) and the genes coding for CBX6 (chromobox homolog 6) and APOBEC3A (apolipoprotein B mRNA editing enzyme, catalytic polypeptide-like 3A). This study is based on 712 bladder cancer patients and 875 controls from 3 different case control studies in Germany. The 4 SNPs of interest (PSCA rs2294008 and rs2978974, FGFR3-TACC3 rs798766, and CBX6-APOBEC3A rs1014971) were determined by real-time polymerase chain reaction. The distribution of the 4 SNPs does not vary significantly between cases and controls in the entire study group and in the 3 local subgroups, including two former highly industrialized areas and a region without such history. Also, no significant differences in the bladder cancer subgroups of MIBC and NMIBC were observed. The 4 investigated SNPs do not noticeably contribute differently to the bladder cancer risk for the bladder cancer subgroups of MIBC and NMIBC.

description: Abstract This research attempted to examine the effect of human capital and human security on the economic growth of Bangladesh employing annual timeseries over the years 1981-2019. The paper also attempted to look into the connection between government spending on health, investment, and economic growth. An econometric framework for non-stationary timeseries was used in the research. The Johansen test showed that there was cointegration between the variables, but neither the VECM nor the ARDL model could establish any meaningful long-term causality. In the VECM model's short-run dynamics, lag-3 human security was identified as being significantly positively related to economic growth, whereas in the ARDL model, lag-3 investment was identified as having a significantly positive effect on economic growth and lag-1 human capital as having a significantly negative impact. According to the Granger causality test, lagged investment and lagged human security have an effect on economic growth, but lagged government health expenditure and lagged human capital do not. The OLS test identified human capital, and investment as having a substantial impact on Bangladesh's economic growth. The research recommends increasing funding for capacity building and human resource development, modernizing agriculture, and ensuring human security.

description: In the last year’s 28th EU PVSEC, the authors [1] presented a six months real-life performance behaviour assessment of the two main inverter technologies used in large-scale grid connected PV stations. This paper is intended to present a full one-year performance comparison between central and multistring inverters. In this context, the main purpose of this research study is to evaluate in detail and create a comprehensive assessment of performance advantages and disadvantages between central and multistring inverters, operating in large PV stations. The comparison assessment will use a full one year real-life data derived from the operation of two 500kWp grid-connected PV stations, located close to the city of Lamia in Central Greece. Both power stations are designed and installed by the same EPC contractor. The same type of polycrystalline modules is used, adopting also the same panel tilt and shading angle. At the same time however, power station "A" is based on the operation of one central inverter, while power station "B" uses 25 multistring inverters. The inverters used in both parks are supplied from the same manufacturer. In this way, the technical design features and the adjacent location of the two PV stations enable in depth analysis via the direct comparison of the inverters’ performance indices as proposed by the IEC 61724 international standard. In this regard, through the analysis of monitoring data, a small advantage for the central configuration is noticed during the first year of operation. Monitoring will be continued and a more detailed insight on the overall performance of the two PV plants will be reported in the future.

description: Large-scale river models are being refined over coastal regions to improve the scientific understanding of coastal processes, hazards and responses to climate change. However, coarse mesh resolutions and approximations in physical representations of tidal rivers limit the performance of such models at resolving the complex flow dynamics especially near the river-ocean interface, resulting in inaccurate simulations of flood inundation. In this research, we propose a machine learning (ML) framework based on the state-of-the-art physics-informed neural network (PINN) to simulate the downscaled flow at the subgrid scale. First, we demonstrate that PINN is able to assimilate observations of various types and solve the one-dimensional (1-D) Saint-Venant equations (SVE) directly. We perform the flow simulations over a floodplain and along an open channel in several synthetic case studies. The PINN performance is evaluated against analytical solutions and numerical models. Our results indicate that the PINN solutions of water depth have satisfactory accuracy with limited observations assimilated. In the case of flood wave propagation induced by storm surge and tide, a new neural network architecture is proposed based on Fourier feature embeddings that seamlessly encodes the periodic tidal boundary condition in the PINN's formulation. Furthermore, we show that the PINN-based downscaling can produce more reasonable subgrid solutions of the along-channel water depth by assimilating observational data. The PINN solution outperforms the simple linear interpolation in resolving the topography and dynamic flow regimes at the subgrid scale. This study provides a promising path towards improving emulation capabilities in large-scale models to characterize fine-scale coastal processes.

description: The hot-spot phenomenon is a relatively frequent problem occurring in current photovoltaic generators. It entails both a risk for the photovoltaic module’s lifetime and a decrease in its operational efficiency. Nevertheless, there is still a lack of widely accepted procedures for dealing with them in practice. This paper presents the IES-UPM observations on 200 affected modules. Visual and infrared inspection, electroluminescence, peak power and operating voltage tests have been accomplished. Hot-spot observation procedures and well defined acceptance and rejection criteria are proposed, addressing both the lifetime and the operational efficiency of the modules. The operating voltage has come out as the best parameter to control effective efficiency losses for the affected modules. This procedure is oriented to its possible application in contractual frameworks.
Meet the parents: the progenitor binary for the supermassive black hole candidate in E1821+643

description: The remnants of binary black hole mergers can be given recoil kick velocities up to $5,000\text{ km s$^{-1}$}$ due to anisotropic emission of gravitational waves. E1821+643 is a recoiling supermassive black hole moving at $\sim 2,100\text{ km s$^{-1}$}$ along the line-of-sight relative to its host galaxy. This suggests a recoil kick of $\sim 2,240\text{ km s$^{-1}$}$. Such a kick is powerful enough to eject E1821+643 from its $M_\text{gal}\sim 2 \times 10^{12}\text{ M}_{\odot}$ host galaxy. In this work, we address the question: what are the likely properties of the progenitor binary that formed E1821+643? Using astrophysically motivated priors, we infer that E1821+643 was likely formed from a binary black hole system with masses of $m_1\sim 1.9^{+5.0}_{-3.8}\times 10^{9}\text{ M}_{\odot}$, $m_2\sim 8.1^{+3.9}_{-3.2} \times 10^{8}\text{ M}_{\odot}$ (90\% credible intervals). The black holes in this binary were likely to be spinning rapidly with dimensionless spin magnitudes of $χ_1 = 0.87^{+0.11}_{-0.26}$, $χ_2 = 0.77^{+0.19}_{-0.37}$. Such a high recoil velocity is impossible for spins aligned to the orbital angular momentum axis. This suggest that E1821+643 merged in hot gas, which is thought to provide an environment where spin alignment from accretion proceeds slowly relative to the merger timescale. We infer that E1821+643 is likely to be rapidly rotating with dimensionless spin $χ = 0.92\pm0.04$. A $2.6 \times 10^9 \text{ M}_{\odot}$ black hole, recoiling from a gas-rich environment at $v\sim 2,240\text{ km s$^{-1}$}$ is likely to persist as an active galactic nuclei for $\sim 860$ Myr, in which time it traverses $\sim 2$ Mpc.

description: In this paper, the tunneling of scalar particles near the event horizons of Riemann space time, BTZ black hole and Schwarzschild-de Sitter black hole are investigated by applying Hamilton-Jacobi equation with Lorentz violation theory in curved space time. The modified Hamilton-Jacobi equation is derived from Klein-Gordon equation of scalar particles induced by Lorentz violation theory in curved space time. The Hawking temperatures of Riemann space time and the BTZ black hole are modified due to the effect of Lorentz violation theory. Moreover, the Bekenstein-Hawking entropy near the event horizon of Schwarzschild-de Sitter black hole is also modified due to Lorentz violation theory. It is observed that the modified values of Hawking temperatures and change in Bekenstein-Hawking entropy depend upon the ether-like vectors $u^α$.

description: To understand the role of the environment in galaxy formation, evolution, and present-day properties, it is essential to study the multi-frequency behavior of different galaxy populations under various environmental conditions. We crossmatch the SDSS DR10 group catalog with GAMA Data Release 2 and Wide-field Survey Explorer (WISE) data to construct a catalog of 1651 groups and 11436 galaxies containing photometric information in 15 different wavebands ranging from ultraviolet (0.152 μm) to mid-infrared (22 μm). We perform the spectral energy distribution (SED) fitting of galaxies using the MAGPHYS code and estimate the rest frame luminosities and stellar masses. We use the 1/Vmax method to estimate the galaxy stellar mass and luminosity functions, and the luminosity density field of galaxies to define the large scale environment of galaxies. The stellar mass functions of both central and satellite galaxies in groups are different in low and high density large scale environments. Satellite galaxies in high density environments have a steeper low mass end slope compared to low density environments, independently of the galaxy morphology. Central galaxies in low density environments have a steeper low mass end slope but the difference disappears for fixed galaxy morphology. The characteristic stellar mass of satellite galaxies is higher in high density environments and the difference exists only for galaxies with elliptical morphologies. Galaxy formation in groups is more efficient in high density large scale environments. Groups in high density environments have higher abundances of satellite galaxies, irrespective of the satellite galaxy morphology. The elliptical satellite galaxies are generally more massive in high density environments. The stellar masses of spiral satellite galaxies show no dependence on the large scale environment.

description: In this work, we propose a methodology to calculate the equivalent single-diode parameters, as well as other characterizing system parameters from operational data, e.g., temperature coefficients, equivalent thermal resistance, or shade profile angle, thus, bypassing the need for the measurement of IV curves. With this approach, a continuous automated assessment of the PV array’s characteristic parameters becomes possible without the cost and time-intensive effort associated with measuring IV curves in the field, but merely as an additional feature of a traditional PV monitoring system.
The methodology is applied on different PV systems with and without local sensors for irradiance and temperature. The uncertainty is assessed and the results are validated by comparison with datasheet values, onsite bservations and literature.

description: We report here on the first results of a systematic monitoring of southern glitching pulsars at the Argentine Institute of Radioastronomy that started in the year 2019. We detected a major glitch in the Vela pulsar (PSR J0835$-$4510) and two small-glitches in PSR J1048$-$5832. For each glitch, we present the measurement of glitch parameters by fitting timing residuals. We then make an individual pulses study of Vela in observations before and after the glitch. We selected 6 days of observations around the major glitch on 2021 July 22 and study their statistical properties with machine learning techniques. We use Variational AutoEncoder (VAE) reconstruction of the pulses to separate them clearly from the noise. We perform a study with Self-Organizing Maps (SOM) clustering techniques to search for unusual behavior of the clusters during the days around the glitch not finding notable qualitative changes. We have also detected and confirm recent glitches in PSR J0742$-$2822 and PSR J1740$-$3015.

description: Quantum battery (QB) is the miniature energy storage and release device and plays a crucial role in future quantum technology. Here, an implementation scheme of a QB is proposed on a superconducting circuit which is composed by $N$ coupled transmon qubits and a one-dimensional transmission line resonator. We derive the Hamiltonian of the QB system and investigate its charging performance by considering three decay channels. We find that the presence of the decay channels suppresses the high oscillation of the energy storage process, thereby realizing a stable and powerful QB. In particular, compared with the resonator decay and the qubit relaxation, the qubit dephasing shows a counterintuitive advantage in our QB. We show that the nearest neighbor interaction always have a positive impact on the stable energy and the coupling only significantly influences the maximum charging power in the fully nondegenerate ground state region. We also demonstrate the feasibility of our approach by evaluating the QB performance under experimental parameters.

Operation of PV Systems and Plants

description: Grid connected solar plants are a good opportunity for their use for research as a secondary objective. In countries were feed-in tariffs are still active, it is possible to include in the design of the solar plant elements for its use for research. In the case of the solar plant presented here both objectives are covered. The solar plant of this work is formed by PV modules of three different technologies: Multicrystalline, amorphous and CdTe. In one part of the solar plant, the three technologies are working at the same conditions, not only ambient conditions but also similar voltage and current input to the inverters. Both the commercial and the experimental parts of the solar plant have their own independent inverters with their meters but are finally connected to the same meter to inject. In this work we analyse the results for the first year of operation of the experimental solar plant. Productions of three different technologies in exactly the same conditions are compared and presented. According to the results, all the three technologies have conversion efficiencies dropping when the temperature increases. Amorphous module experiences the lesser reduction, whereas the multicrystalline module suffers the most.

description: Tidal dissipation is the main driver of orbital evolution of natural satellites and a key point to understand the exoplanetary system configurations. Despite its importance, its quantification from observations still remains difficult for most objects of our own Solar system. In this work, we overview the method that has been used to determine, directly from observations, the tidal parameters, with emphasis on the Love number k2 and the tidal quality factor Q. Up-to-date values of these tidal parameters are summarized. Last, an assessment on the possible determination of the tidal ratio k2/Q of Uranus and Neptune is done. This may be particularly relevant for coming astrometric campaigns and future space missions focused on these systems.

description: 29th European Photovoltaic Solar Energy Conference and Exhibition; 2674-2679
description: The purpose of this work is to develop a methodology for comparing plant configuration (number of inverters, string size and cabling configuration) based on the LCOE (Levelized Cost of Energy) and availability. The model used in this methodology includes the implementation and the operation costs (repair parts and labor for corrective and preventive maintenance), reliability model of each component of the power plant, from the PV modules to the main disconnect switch; spare parts management; statistical models for time to repair, repair team and component costs and delays; and finally, the production yield available for each component. Three different configurations are analyzed: one with centralized inverter topology and two with decentralized inverter topology. A reliability block diagram model was built for each configuration and simulation results on these three options are presented to demonstrate the effectiveness of the methodology.
Accumulating errors in tests of general relativity with gravitational waves: overlapping signals and inaccurate waveforms

description: Observations of gravitational waves (GWs) from compact binary coalescences provide powerful tests of general relativity (GR), but systematic errors in data analysis could lead to incorrect scientific conclusions. This issue is especially serious in the third-generation GW detectors in which the signal-to-noise ratio (SNR) is high and the number of detections is large. In this work, we investigate the impacts of overlapping signals and inaccurate waveform models on tests of GR. We simulate mock catalogs for Einstein Telescope and Cosmic Explorer and perform parametric tests of GR using waveform models with different levels of inaccuracy. We find the systematic error in non-GR parameter estimates could accumulate toward a false deviation from GR when combining results from multiple events, although a bayesian model selection analysis may not favour a deviation. Waveform inaccuracies contribute most to the systematic errors, but multiple overlapping signals could magnify the effects of systematics due to the incorrect removal of signals. We also point out that testing GR using selected ''golden binaries'' with high SNR is even more vulnerable to false deviations from GR. The problem of error accumulation is universal; we emphasize that it must be addressed to fully exploit the data from third-generation GW detectors, and that further investigations, particularly in waveform accuracy, will be essential.

description: Photovoltaic system designers use information about the outdoor behaviour of photovoltaic (PV) modules to improve their designs and to make photovoltaic installations more cost effective. The outdoor measurement of these valuable data is not frequently carried out due the implementation of some type of automatic ad hoc measurement system is usually necessary to cope an experimental campaign. The reliability of these ad hoc automatic systems is usually the main concern of the designer and the end-user, especially when a long experimental
process has to be conducted. In this work, a robust and reliable design for an automatic monitoring system to assess the outdoors behaviour of a PV module/array is reported on. The build equipment is composed by several units, by which the PV module current-voltage (I-V, hereafter) curve and the meteorological variables -including the impinging solar spectral distribution- are collected. The developed experimental setup allows to record sequentially the I-V curve up to four photovoltaic modules. The implemented monitoring system was successfully used to analyse the influence of the module temperature and/or environmental parameters -like the solar spectrum- on PV module performance. Thus, some sound results and conclusions were previously published using the information obtained from this monitoring system from November 2011 to July 2014.

description: Accurate and reliable forecasting of photovoltaic system’s power output is an essential supporting technique that will facilitate grid-connected photovoltaic systems. This paper aims to evaluate several artificial-intelligence-based forecasting techniques to predict the power production of a 24 kW photovoltaic system in Melaka, Malaysia. This location is influenced by equatorial climate conditions, having no distinct seasonal variation and high amount of cloud cover. The data comprises five-minute averaged values of global irradiance, backmodule temperature, and inverter AC output, recorded throughout the year. Findings show that LS-SVM produced the best forecast in terms of the evaluation metrics used followed by the original SVM at a close second.

description: A statistical approach based on the Weisskopf evaporation theory has been developed to describe the de-excitation process of highly excited heavy and superheavy nuclei, in particular for the proton-rich nuclei. The excited nucleus is cooled by evaporating $γ$-ray, light particles (neutrons, protons, $α$ etc) in competition with the binary fission, in which the structure effects (shell correction, fission barrier, particle separation energy) contribute to the processes. The formation of residual nuclei is evaluated via sequential emission of possible particles above the separation energies. The available data of fusion-evaporation excitation functions in the $^{28}$Si+$^{198}$Pt reaction can be reproduced nicely well within the approach.

description: The temporal variability of solar irradiance at small time scales ranging from 1 second to 2 minutes was studied to characterize the short term fluctuations in irradiance at high latitudes. The change in irradiance at time scales of 1, 5, 10, 30, 60 and 120 seconds were calculated from irradiance data measured at a test station in Grimstad, Norway, over a one year period. The number of occurrences of different ramps in irradiance was analyzed at different time scales. The largest change in irradiance was detected over a 2 minute time interval with an amplitude of 995 W/m2. Similar amplitudes were detected at time intervals of 30 and 60 seconds. However, such large changes (above 900 W/m2) occur only a very few times over a year. The distributions of irradiance fluctuations at different time scales show that although, large changes in the range of above 600 W/m2 occur at time scale of 1 s, the number of occurrences over a year is significantly smaller than the number of occurrences at time scales above 5 s. Further, the
number of occurrences of high magnitude fluctuations over a year particularly in the range of 500 W/m2 – 900 W/m2 does not show significant dependence on the time scale for time scales above 5 s.
