description: PG1247+267 is one of the most luminous known quasars at $z\sim2$ and is a strongly super-Eddington accreting SMBH candidate. We obtained NuSTAR data of this intriguing source in December 2014 with the aim of studying its high-energy emission, leveraging the broad band covered by the new NuSTAR and the archival XMM-Newton data. Several measurements are in agreement with the super-Eddington scenario for PG1247+267: the soft power law ($Γ=2.3\pm0.1$); the weak ionized Fe emission line and a hint of the presence of outflowing ionized gas surrounding the SMBH. The presence of an extreme reflection component is instead at odds with the high accretion rate proposed for this quasar. This can be explained with three different scenarios; all of them are in good agreement with the existing data, but imply very different conclusions: i) a variable primary power law observed in a low state, superimposed on a reflection component echoing a past, higher flux state; ii) a power law continuum obscured by an ionized, Compton thick, partial covering absorber; and iii) a relativistic disk reflector in a lamp-post geometry, with low coronal height and high BH spin. The first model is able to explain the high reflection component in terms of variability. The second does not require any reflection to reproduce the hard emission, while a rather low high-energy cutoff of $\sim100$ keV is detected for the first time in such a high redshift source. The third model require a face-on geometry, which may affect the SMBH mass and Eddington ratio measurements. Deeper X-ray broad-band data are required in order to distinguish between these possibilities.

Large PV Power Plants and Distributed PV: System Aspects and Grid Connection

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 4308-4311
description: The photovoltaic market is constantly growing thanks to the cost reduction achieved by the
photovoltaic industry. In order to take the right investment decisions it is important to have an insight on the
performance of the different systems. Usually these decisions are taken based on simulated performance. From this
perspective it is important that the predictions have a good correlation with the real performance of the installations.
Traditional engineering tools used to assess the performance of the PV systems work with reasonable accuracy for
systems based on conventional c-Si technologies. Although, the performance assessment of systems based on new
thin film technologies have not been achieved in the standard tools with the same level of accuracy. The development
of reliable performance models requires the validation of the simulation results with consistent data obtained from the
operation of photovoltaic plants. In this frame, a detailed monitoring of the plant with capabilities to assess the
performance of each independent component is required. In this paper we are going to compare the yield and
performance ratio (PR) results from large ground mounted PV plants built up with different technologies. T-Solar has
an installed power of 161 MW all over Spain, being 15MW built with a-Si thin film technology. The analysis will be
done over one full year of production. The work will use consolidated results measured at the control center of
T-Solar in Madrid and will compare the real data with simulations.

description: beta-Bi2Pd compound has been proposed as another example of a multi-gap superconductor [Y. Imai et al., J. Phys. Soc. Jap. 81, 113708 (2012)]. Here, we report on measurements of several important physical quantities capable to show a presence of multiple energy gaps on our superconducting single crystals of beta-Bi2Pd with the critical temperature Tc close to 5 K. The calorimetric study via a sensitive ac technique shows a sharp anomaly at the superconducting transition, however only a single energy gap is detected. Also other characteristics inferred from calorimetric measurements as the field dependence of the Sommerfeld coefficient and the temperature and angular dependence of the upper critical magnetic field point unequivocally to standard single s-wave gap superconductivity. The Hall-probe magnetometry provides the same result from the analysis of the temperature dependence of the lower critical field. A single-gapped BCS density of states is detected by the scanning tunneling spectroscopy measurements. Then, the bulk as well as the surface sensitive probes evidence a standard conventional superconductivity in this system where the topologically protected surface states have been recently detected by ARPES [M. Sakano et al., Nature Comm. 6, 8595 (2015)] .

description: In this paper, to measure the performance test of photovoltaic (PV) module, we have comparison test
and uncertainty of performance using six kinds of solar simulators for better measurement result. Also, we calculate
the uncertainty of measurement using Pasanb Solar Simulator of KIER which is Standard Test Laboratory in
Korea. From 1st results, we improved the problem and did 2nd test. Finally three module makers' reduced their
discrepancy but one laboratory and maker didn't show measurement improvement because of test environment
condition and position change of reference solar cell. This is round robin test result for minimizing the performance
discrepancy between laboratories and module makers. Also, we tried to have exactness of measurement of maximum
power by calculating uncertainty and comparing test between domestic and foreign laboratories for solar simulators.

description: Objective: The study investigates the effect on cooperation in multiplayer games, when the population from which all individuals are drawn is structured - i.e. when a given individual is only competing with a small subset of the entire population. Method: To optimize the focus on multiplayer effects, a class of games were chosen for which the payoff depends nonlinearly on the number of cooperators - this ensures that the game cannot be represented as a sum of pair-wise interactions, and increases the likelihood of observing behaviour different from that seen in two-player games. The chosen class of games are named "threshold games", and are defined by a threshold, $M > 0$, which describes the minimal number of cooperators in a given match required for all the participants to receive a benefit. The model was studied primarily through numerical simulations of large populations of individuals, each with interaction neighbourhoods described by various classes of networks. Results: When comparing the level of cooperation in a structured population to the mean-field model, we find that most types of structure lead to a decrease in cooperation. This is both interesting and novel, simply due to the generality and breadth of relevance of the model - it is likely that any model with similar payoff structure exhibits related behaviour. More importantly, we find that the details of the behaviour depends to a large extent on the size of the immediate neighbourhoods of the individuals, as dictated by the network structure. In effect, the players behave as if they are part of a much smaller, fully mixed, population, which we suggest an expression for.

PV module manufactures, installation year and area. Degradation phenomenon is commonly checked with corrosion
in interconnected ribbon, EVA delamination and breakage of bypass diode. Also, the PV modules over 20 years have
yellow discoloring, humidity intrusion and white discoloring, seriously. Some has glass breakage cause by hot spot.
In that cases the maximum output power has reduced to 17.8% ~ 47.5% from initial value at standard test condition

description: An experimental realization of a heat exchanger with commercial thermoelectric generators (TEGs) is presented. The power producing capabilities as a function of flow rate and temperature span are characterized for two different commercial heat transfer fluids and for three different thermal interface materials. The device is shown to produce 2 W per TEG or 0.22 W cm$^{-2}$ at a fluid temperature difference of 175 $^\circ$C and a flow rate per fluid channel of 5 L min$^{-1}$. One experimentally realized design produced 200 W in total from 100 TEGs. For the design considered here, the power production is shown to depend more critically on the fluid temperature span than on the fluid flow rate. Finally, the temperature span across the TEG is shown to be 55% to 75% of the temperature span between the hot and cold fluids.

description: MPhil Thesis
Background: A growing trend over the last few years is storage outsourcing. Where the concept of third-party data warehousing has become more popular. This trend prompts serval interesting security issues. One of the biggest issues with third-party data providers is accountability. This thesis, reviews two schemas/ algorithms that allows users to check the integrity and availability of their outsourced data on untrusted data stores. The reviewed schemas are Provable Data Possession (PDP) and Proofs of Retrievability (POR). Both are cryptographic protocols designed to give clients the assurance needed that their data is secure on the untrusted file storage. Furthermore, a conceptual framework is proposed to mitigate the weaknesses of the current storage solutions.
Results: PDP and POR schemas do have different responsibilities. PDP main aim is to ensure that the client file is intact and has not been tampered, whereas POR main aim is to guarantee that the client can retrieve the file even with small file corruption. Both have real?world usage and is critical for today’s data-centric world.
Conclusions: The differences between PDP and POR schemas are becoming less with each new iteration. This thesis demonstrates the difference and weaknesses in both approaches and provides a conceptual model as a building block to further the research in this area.
A protocol for transdifferentiation of human cardiac fibroblasts into endothelial cells via activation of innate immunity

description: Endothelial cells (ECs) have emerged as key pathogenic players in cardiac disease due to their proximity with cardiomyocytes. Induced pluripotent stem cells (iPSCs) have been employed to generate ECs. However, it may be more clinically relevant to transdifferentiate fibroblasts into ECs directly without introducing pluripotent or virally driven transcription factors. Here, we present a protocol that describes the direct conversion of human cardiac fibroblasts into ECs by leveraging the innate immune system. Our protocol produces bona fide human ECs with 95%–98% purity by first passage.

description: Community networks differ from regular networks by their organic growth patterns -- there is no central planning body that would decide how the network is built. Instead, the network grows in a bottom-up fashion as more people express interest in participating in the community and connect with their neighbours. People who participate in community networks are usually volunteers with limited free time. Due to these factors, making the management of community networks simpler and easier for all participants is the key component in boosting their growth. Specifics of individual networks often force communities to develop their own sets of tools and best practices which are hard to share and do not interoperate well with others. We propose a new general community network management platform nodewatcher that is built around the core principle of modularity and extensibility, making it suitable for reuse by different community networks. Devices are configured using platform-independent configuration which nodewatcher can transform into deployable firmware images, eliminating any manual device configuration, reducing errors, and enabling participation of novice maintainers. An embedded monitoring system enables live overview and validation of the whole community network. We show how the system successfully operates in an actual community wireless network, wlan Slovenija.

description: GeoPAT 2 (Geospatial Pattern Analysis Toolbox) is a standalone suite of modules written in C and dedicated to analysis of large Earth Science datasets in their entirety using spatial and/or temporal patterns. Global scale, high resolution spatial datasets are available but are mostly used in small pieces for local studies. GeoPAT enables studying them in their entirety. GeoPAT’s core idea is to tessellate global spatial data into grid of square blocks of original cells (pixels). This transforms data from its original form (huge number of cells each having simple content) to a new form (much smaller number of supercells/blocks with complex content). Complex cell contains a pattern of original variable. GeoPAT provides means for succinct description of such patterns and for calculation of similarity between patterns. This enables spatial analysis such as search, change detection, segmentation, and clustering to be performed on the grid of complex cells (local patterns).

description: Raman micro-spectroscopy is well suited for studying a variety of properties and has been applied to wide- ranging areas. Combined with tuneable temperature, Raman spectra can offer even more insights into the properties of materials. However, previous designs of variable temperature Raman microscopes have made it extremely challenging to measure samples with low signal levels due to thermal and positional instability as well as low collection efficiencies. Thus, contemporary Raman microscope has found limited applicability to probing the subtle physics involved in phase transitions and hysteresis. This paper describes a new design of a closed-cycle, Raman microscope with full polarization rotation. High collection efficiency, thermal and mechanical stability are ensured by both deliberate optical, cryogenic, and mechanical design. Measurements on two samples, Bi2Se3 and V2O3, which are known as challenging due to low thermal conductivities, low signal levels and/or hysteretic effects, are measured with previously undemonstrated temperature resolution.

description: Many novel CRISPR-based genome-editing tools, with a wide variety of applications, have been developed in the past few years. The original CRISPR–Cas9 system was developed as a tool to alter genomic sequences in living organisms in a simple way. However, the functions of new CRISPR tools are not limited to conventional genome editing mediated by non-homologous end-joining or homology-directed repair but expand into gene-expression control, epigenome editing, single-nucleotide editing, RNA editing and live-cell imaging. Furthermore, genetic perturbation screening by multiplexing guide RNAs is gaining popularity as a method to identify causative genes and pathways in an unbiased manner. New CRISPR tools can also be applied to ex vivo or in vivo therapeutic genome editing for the treatment of conditions such as hyperlipidaemia. In this Review, we first provide an overview of the diverse new CRISPR tools that have been developed to date. Second, we summarize how these new CRISPR tools are being used to study biological processes and disease mechanisms in cardiovascular research and medicine. Finally, we discuss the prospect of therapeutic genome editing by CRISPR tools to cure genetic cardiovascular diseases.

description: Photovoltaic modules are used to produce electricity. The amount of energy produced depends on the
operating conditions of the photovoltaic module, specially depends on the temperature of the solar cells. The
temperature of each element of the model is a function of the ambient conditions and of the amount of energy
produced by the solar cells. Thermal and electrical behaviors are influenced each other. This is the main reason
because of a thermal and electrical model has been developed. In previous models simplifications of the electrical or
thermal behavior were made in order to obtain the electrical or thermal characterization of the PV module. This
model does not use these simplifications and simulates both behaviors. This is not only useful for knowing the
temperature and the power generated but it also gives a description of how the electrical part and the thermal part are
influenced each other. This influence can also be measured under certain conditions. The main disadvantage of
working with both parts is that the model becomes very complex and special numerical methods should be used. In
other way the comprehension of these influences can lead to new simplifications and to easier models.

description: We discuss the emergence of classical trajectories in Bohmian Mechanics (BM), when a macroscopic object interacts with an external environment. We show that in such a case the conditional wave function of the system follows a dynamics which, under reasonable assumptions, corresponds to that of the Ghirardi-Rimini-Weber (GRW) collapse model. As a consequence, Bohmian trajectories evolve classically. Our analysis also shows how the GRW (istantaneous) collapse process can be derived by an underlying continuous interaction of a quantum system with an external agent, thus throwing a light on how collapses can emerge from a deeper level theory.

description: Resonant nuclear reactions are a powerful tool for the determination of the amount and profile of hydrogen in thin layers of material. Usually, this tool requires the use of a standard of well-known composition. The present work, by contrast, deals with standard-less hydrogen depth profiling. This approach requires precise nuclear data, e.g. on the widely used $^{1}$H($^{15}$N,$αγ$)$^{12}$C reaction, resonant at 6.4\,MeV $^{15}$N beam energy. Here, the strongly anisotropic angular distribution of the emitted $γ$-rays from this resonance has been re-measured, resolving a previous discrepancy. Coefficients of (0.38$\pm$0.04) and (0.80$\pm$0.04) have been deduced for the second and fourth order Legendre polynomials, respectively. In addition, the resonance strength has been re-evaluated to (25.0$\pm$1.5)\,eV, 10\% higher than previously reported. A simple working formula for the hydrogen concentration is given for cases with known $γ$-ray detection efficiency. Finally, the absolute approach is illustrated using two examples.

modular character of several elements of this capacitive load implemented, together with an innovative control stage,
allows to characterize any PV system without depending on its size. The implemented prototypes have been tested
successfully during an experimental campaign where the I-V curves of PV modules, small PV generators and large
PV generators, have been obtained and compared with the results of a commercial electronic load.

description: The increased interest in sustainable agricultural systems has led to significant developments in cropping practices that allow to preserve crop productivity and reduce the reliance on herbicides and nitrogen fertilizers. Relay intercropping of legumes in wheat may represent a proficient practice to maintain crop productivity, improve soil fertility and support weed control at crop rotation level, if appropriate associated legumes are used. The objective of this study is to select suited legumes for relay intercropping with durum wheat in central Italy among a wide range of taxa (Medicago sativa, Medicago varia, Medicago lupulina, Trifolium repens, Hedysarum coronarium, Trifolium alexandrinum, Trifolium incarnatum, Trifolium resupinatum, Vicia villosa, Medicago polymorpha, Medicago rotata, Medicago scutellata, Medicago truncatula, and, 3 subsp. of Trifolium subterraneum). This study was carried out at the Centre for Agro-Environmental Research “Enrico Avanzi” in Pisa (Italy) in 2017/18 and repeated in the 2018/19 cropping season. According to the results obtained during 2017/18, legumes were reduced in 2018/19 excluding the least performing ones. The experiment was organized in a randomized complete block design with four replicates and the sole wheat crop as control. No pesticides or fertilizers were used. The evaluation was focused on i) legume establishment in the already developed wheat, ii) grain production and quality, iii) weed control before and after the wheat harvest, iv) legume persistence and growth after wheat harvest and, v) effects on the following crop. Legumes, indeed, were incorporated into the soil the following spring and forage sorghum was seeded. Results of this study showed that relay intercropped legumes preserved wheat production and reduced weed biomass up to the 70% in comparison with the control. After wheat harvest legumes persisted in the field, as dead mulch or cover crop according to the different life cycle of the tested legumes, until the sowing of sorghum. Dead mulch of annual legumes resulted unsuitable to contrast weeds while, perennial and annual self-seeding legumes as M.polymorpha and T.subterraneum, showed overall good weed control and biomass accumulation. Legume biomass at spring soil incorporation, was the most important factor related with sorghum production. Sorghum, preceded by T. subterranum, H. coronarium and T. repens, had a higher biomass production than the control and was comparable with the productive level that can be obtained under conventional systems. The overall assessment of legumes used in this study, allows to select the most suited ones for relay intercropping with durum wheat for the local environmental condition.

description: In this paper we investigate the robustness of the quantum correlations against the environment effects in various opto-mechanical bipartite systems. For two spatially separated opto-mechanical cavities, we give analytical formula for the global covariance matrix involving two mechanical modes and two optical modes. The logarithmic negativity as an indicator of the degree of entanglement and the Gaussian quantum discord which is a witness of quantumness of correlations are used as quantifiers to evaluate the different pairwise quantum correlations in the whole system. The evolution of the quantum correlations existing in this opto-mechanical system are analyzed in terms of the thermal bath temperature, squeezing parameter and the opto-mechanical cooperativity. We find that with desirable choice of these parameters, it is possible either enhance or annihilate the quantum correlations in the system. Various scenarios are discussed in detail.

description: We report on efficient nonlinear generation of ultrafast, higher order "perfect" vortices at the green wavelength. Based on Fourier transformation of the higher order Bessel-Gauss beam generated through the combination of spiral phase plate and axicon we have transformed the Gaussian beam of the ultrafast Yb-fiber laser at 1060 nm into perfect vortices of power 4.4 W and order up to 6. Using single-pass second harmonic generation (SHG) of such vortices in 5-mm long chirped MgO-doped, periodically poled congruent LiNbO$_3$ crystal we have generated perfect vortices at green wavelength with output power of 1.2 W and vortex order up to 12 at single-pass conversion efficiency of 27% independent of its order. This is the highest single-pass SHG efficiency of any optical beams other than Gaussian beams. Unlike the disintegration of higher order vortices in birefringent crystals, here, the use of quasi-phase matching process enables generation of high quality vortices even at higher orders. The green perfect vortices of all orders have temporal and spectral width of 507 fs and 1.9 nm, respectively corresponding to a time-bandwidth product of 1.02.

Silicon Solar Cell Characterisation and Modelling

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 1530-1533
description: The purpose of this work is to study rear-side contact schemes in terms of metallization and Back
Surface Field (BSF) characterization of industrial-type Passivated Emitter and Rear Cells (PERC local Al-BSF). The
approach used to characterize these highly doped regions is the Scanning Spreading Resistance Microscopy technique
(SSRM). The SSRM technique gives the carrier distribution information with high spatial resolution.
By using this technique, it was possible to obtain the exact resistance profiles of the BSF layers, and from that,
quantify the doping level for the local Al BSF. Due to this high spatial resolution, a gradient in the doping level
within the BSF has been possible to be detected, showing the effect of the cooling down process. Two different Al
thicknesses have been applied to evaluate its impact on the BSF. It has been found that the thicker the Al layer
applied for the local BSF case, the thicker the BSF was formed, as it occurs for Al screen printed full BSF case,
although the thermodynamic behaviour and the contact area are different.

Large PV Power Plants and Distributed PV: System Aspects and Grid Connection

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 4272-4275
description: Long-term monitoring of photovoltaic (PV) fields is of increasing interest for PV customers.
Subsiding fees recompense produced energy; as a consequence, prompt identification of malfunctioning or failures
is of paramount importance. In this paper, we present an improved version of a recently-developed monitoring
electronic circuit devised to measure the effective voltage, the open-circuit voltage, and the short-circuit current of
string-connected solar panels. The system substitutes the junction box, is fully self-powered, and does not require
additional cables thanks to wireless communication. The experiments shown in the paper clearly demonstrate the
reliability and usefulness of the system for continuous monitoring of PV fields.

Large PV Power Plants and Distributed PV: System Aspects and Grid Connection

description: 26th European Photovoltaic Solar Energy Conference and Exhibition; 4281-4282
description: Performance of the photovoltaic systems suffers from inappropriate level of supervisory. Limited
availability of the information about key system parameters and lack of expert knowledge of the users are the most
commonly found problems. In large scale installations, due to high level of complexity, faults become more likely to
happen and more difficult to be found. In extreme they may stay uncovered for long periods of time. It decreases
financial performance of the PV system putting investment at risk. In presented paper novel, wireless ZigBee
technology has been applied to develop robust, accurate, easy to install, low cost and autonomous sensing solution
for photovoltaic supervisory systems.

description: 25th European Photovoltaic Solar Energy Conference and Exhibition / 5th World Conference on Photovoltaic Energy Conversion, 6-10 September 2010, Valencia, Spain; 3009-3012
description: Hydrogenated microcrystalline silicon (μc-Si:H) growth by very high frequency plasma-enhanced
chemical vapor deposition (VHF-PECVD) is studied in an industrial-type parallel plate KAI reactor. Both plasma
and material characterization techniques allow the assessment and control of critical deposition parameters for
the fabrication of high quality material. In particular the silane depletion conditions of all the plasma regimes
were studied. The role of the intrinsic stress of the μc-Si:H active layer is discussed after reviewing two different
series results done in low and high growth rates regimes. It is shown that stress value on its own cannot be a
determinant factor for the material quality. Results highlight the difficulties to assess the material quality
differences above a certain threshold when the material is actually incorporated into a solar cell device, as neither
defect density through Fourier-transform photocurrent spectroscopy (FTPS), infrared spectroscopy (FTIR) nor
stress measurement could discriminate between them. Although different plasma conditions could provide the
growth of μc-Si:H material with very similar electrical bulk properties, some would differ and tend to favor the
formation of cracks on rough substrates, becoming then the main limiting factor of the overall cell efficiency.

description: Solar cells based on amorphous silicon are an attractive route to produce flexible solar cells. The n-i-p
configuration allows the use of low cost flexible substrates such as poly-ethylene-naphtalate (PEN). In this work we aim
at obtaining a high open circuit voltage (Voc) without changing intrinsic layer dilution and temperature. It involves a
well adapted p-layer which is required to fulfill the following conditions: to create a high built-in Voltage (Vbi) through
the junction, to be transparent and thin enough in order to minimize light absorption, to yield a low level of
recombination at the interface between the intrinsic (i) and the p-doped (p) layer, and finally to allow a proper contact to
the transparent conductive oxide (TCO). We found that p-layers deposited in the protocrystalline growth regime lead to
an increase up to 45 mV. Our solar cell deposition process can be directly applied to PEN substrate.
