description: The light cone sum rules method is used in studying the radiative decays $Σ_Q \to Λ_Q γ$ and $Ξ^\prime_Q \to Ξ_Q γ$. Firstly, the sum rules for the form factor $F_2(Q^2=0)$ responsible for these transitions is constructed. Using this result the decay widths of the above--mentioned decays are calculated and analyzed. A comparison of our predictions on the decay widths of considered transitions with the predictions of the other approaches is presented.

description: The ultimate goal of quantum information science is to build a global quantum network, which enables quantum resources to be distributed and shared between remote parties. Such quantum network can be realized by all fiber elements, which takes advantage of low transmission loss,low cost, scalable and mutual fiber communication techniques such as dense wavelength division multiplexing. Therefore high quality entangled photon sources based on fibers are on demanding for building up such kind of quantum network. Here we report multiplexed polarization and timebin entanglement photon sources based on dispersion shifted fiber operating at room temperature. High qualities of entanglement are characterized by using interference, Bell inequality and quantum state tomography. Simultaneous presence of entanglements in multichannel pairs of a 100GHz DWDM shows the great capacity for entanglements distribution over multi-users. Our research provides a versatile platform and moves a first step toward constructing an all fiber quantum network.

description: This comparative study of two PV grid-connected systems discusses their operation, and their production
and generation costs, using a new procedure that requires only a small number of easily obtained parameters. The
procedure compares the real PV production of the two installations at the same location. Their construction shares the
same design criteria -PV panels, panel support system and wiring- and the facilities are exposed to the same variations in
atmospheric temperature and levels of solar radiation. They differ with regard to their inverters: the first plant has a
central inverter and the second has a multi-string inverter configuration. Analysis of the data gathered over lengthy
periods of operation highlights the importance of the layout of the installations and their components, which assists future
maintenance decisions and modifications to the facilities.

description: Protoplanetary disks dissipate rapidly after the central star forms, on time-scales comparable to those inferred for planet formation. In order to allow the formation of planets, disks must survive the dispersive effects of UV and X-ray photoevaporation for at least a few Myr. Viscous accretion depletes significant amounts of the mass in gas and solids, while photoevaporative flows driven by internal and external irradiation remove most of the gas. A reasonably large fraction of the mass in solids and some gas get incorporated into planets. Here, we review our current understanding of disk evolution and dispersal, and discuss how these might affect planet formation. We also discuss existing observational constraints on dispersal mechanisms and future directions.

description: Aims. The main-sequence B-type star $ζ$ Cassiopeiae is known as a N-rich star with a magnetic field discovered with the Musicos spectropolarimeter. We model the magnetic field of the star by means of 82 new spectropolarimetric observations of higher precision to investigate the field strength, topology, and effect. Methods. We gathered data with the Narval spectropolarimeter installed at Télescope Bernard Lyot (TBL, Pic du Midi, France) and applied the least-squares deconvolution technique to measure the circular polarisation of the light emitted from $ζ$ Cas. We used a dipole oblique rotator model to determine the field configuration by fitting the longitudinal field measurements and by synthesizing the measured Stokes V profiles. We also made use of the Zeeman-Doppler Imaging technique to map the stellar surface and to deduce the difference in rotation rate between the pole and equator. Results. $ζ$ Cas exhibits a polar field strength $B_{\rm pol}$ of 100-150 G, which is the weakest polar field observed so far in a massive main-sequence star. Surface differential rotation is ruled out by our observations and the field of $ζ$ Cas is strong enough to enforce rigid internal rotation in the radiative zone according to theory. Thus, the star rotates as a solid body in the envelope. Conclusions. We therefore exclude rotationally-induced mixing as the cause of the surface N-enrichment. We discuss that the transport of chemicals from the core to the surface by internal gravity waves is the most plausible explanation for the nitrogen overabundance at the surface of $ζ$ Cas.

description: During derating, the power output is reduced on purpose by leaving the maximum power point (MPP).
At the PV plant investigated in this work, when the array‘s output power surmounts a certain threshold value, the
operating voltage is abruptly increased, thereby shifting to an operating point with lower output power. This leads to
unstable zigzag-shaped current and voltage. In order to determine yield losses due to derating, high resolution data of
electrical and climatic values of several strings were recorded during regular operation of the PV plant. From this
data, the actual yield, theoretically possible yield (under the measured ambient conditions, but without derating) and
the yield loss were calculated. Additionally, the share of the yield loss that originated from the instability of current
and voltage was reckoned separately. Derating causes yield losses. A large part of these losses is caused solely by the
fact that the operating point is not held steady at the threshold value of the output power. In the data analyzed, up to
50% of the yield losses during derating originated from the instability of the operating point. In order to minimize
yield losses due to derating, the instability of the operating point should be kept as low as possible.

description: This research maps the knowledge translation process for two different types of nanotechnologies applied to cancer: liposomes and metallic nanostructures (MNs). We performed a structural analysis of citation networks and text mining supported in controlled vocabularies. In the case of liposomes, our results identify subnetworks (invisible colleges) associated with different therapeutic strategies: nanopharmacology, hyperthermia, and gene therapy. Only in the pharmacological strategy was an organized knowledge translation process identified, which, however, is monopolized by the liposomal doxorubicins. In the case of MNs, subnetworks are not differentiated by the type of therapeutic strategy, and the content of the documents is still basic research. Research on MNs is highly focused on developing a combination of molecular imaging and photothermal therapy.

description: Over the last years, building-integrated PV solutions have gained increasing importance. However,
this new trend comes with the challenge of efficiently handling partial shading of PV-equipped architectural
structures, e.g. by nearby buildings, chimneys or roof vents. To maximize the energy yield under such conditions,
one possible solution is to install module-wise dc/dc converters that are deployed as maximum power point
(MPP) trackers. Here, we present a novel MPP tracking dc/dc converter called IMOS. IMOS unifies an
outstandingly high dc/dc peak efficiency of up to 99,4 % with a highly efficient MPP tracking algorithm
combining a “ramp search” method with a “perturb and observe” method to assure the identification of the global
MPP. Furthermore, the device supports powerline communication and includes a safety circuit to short-circuit the
PV module in case of hazards or maintenance. For performance evaluation, the tracker was mounted on a PV test
station and subjected to systematically varied partial shading conditions. The results were analyzed and compared
to i) the non-MPP tracking (reference) condition and ii) the performance of different commercially available
tracking devices.

description: In this paper, a PV inverter control scheme is presented suitable for operation under distorted and
unbalanced grid voltage, as well as when the grid frequency varies, as is the case in isolated systems such as those in
non-interconnected islands. The analysis is performed both in the frequency and time domains, using a suitable
linearized model, as well as the full non-linear electrical model of the system. The objective is to determine the main
factors affecting the system dynamic behavior as well as the power quality characteristics of the PV output current in
presence of distorted grid conditions. To this end, a comparative assessment of the proposed PV inverter controller
versus a conventional one is performed.

description: Microelectromechanical systems, which can be moved or rotated with nanometre precision, already find applications in such fields like radio-frequency electronics, micro-attenuators, sensors and many others. Especially interesting are those which allow fine control over the motion on atomic scale due to self-alignment mechanisms and forces acting on the atomic level. Such machines can produce well-controlled movements as a reaction to small changes of the external parameters. Here we demonstrate that, for the system of graphene on hexagonal boron nitride, the interplay between the van der Waals and elastic energies results in graphene mechanically self-rotating towards the hexagonal boron nitride crystallographic directions. Such rotation is macroscopic (for graphene flakes of tens of micrometres the tangential movement can be on hundreds of nanometres) and can be used for reproducible manufacturing of aligned van der Waals heterostructures.

description: Density functional theory calculations with a correction of the long-range dispersion force, namely the van der Waals (vdW) force, are performed for SiC polytypes. The lattice parameters are in good agreement with those obtained from experiments. Furthermore, the stability of the polytypes in the experiments, which show 3C-SiC as the most stable, are reproduced by the present calculations. The effect of the vdW force on the electronic structure and the stability of polytypes are discussed. We observe that the vdW interaction is more sensitive to the cubic site than the hexagonal site. Thus, the influence of the vdW force increases with decreasing the hexagonality of the polytype, which results in the confirmation that the most stable polytype is 3C-SiC.

description: The degree of PID degradation of a module can be measured quantitatively by maximum power determination
at standard test conditions or low irradiance but without information of the individual cells. Electroluminescence (EL)
imaging with test currents close to short circuit current or low test currents shows details but no qualitative values. Additional
analysis methods are used to get further information:
• The shunt resistance (Rsh) of individual cells can be determined by shading of single cells in the module. The
comparison of the I-V curves of the unshaded module and the module with one shaded cell enables to measure the
individual shunt resistance of the shaded cell. With this method it is possible to early detect PID and to quantify EL
images for simulating the degradation and regeneration process.
• Infrared (IR) imaging of modules in the direct sunlight is the most suitable method for getting an estimation of the
degree of PID degradation during the operation of modules in the system. Typical PID IR patterns (warmer cells
close to the bottom frame or patchwork patterns) and the position of the module close to the negative end of the
module string are strong hints for PID effects.
The aim of this work is to show different test methods and to arrive at a test procedure for early detection and
characterization of the PID effects on degraded modules in the field and in the laboratory.

description: This paper will summarise some of the findings from an Engineering Doctoral project, spanning three years. The research is about degree apprenticeships in England, specifically the ones in civil engineering at Level 6. The new Apprenticeship Standards were approved in 2017, with the first wave of civil engineering Degree Apprentices emerging in 2020. The paper will seek to understand how learner approaches to the apprenticeship have changed within a year and draw out any improvements that will support new ways of working with specific reference to Covid. The research adopted an established methodology, gathering qualitative data from two questionnaires taken a year apart. Software analyses was undertaken to uncover any underlying constructs between the questionnaires. The research will lead tripartite contributors to evaluate and consider how to support apprenticeships. This research will be added to early body of works for degree apprenticeships and will present practical examples of interventions that could be used by contributors to lead to successful outcomes.

description: The 1-diode model [1] is commonly used in many simulation programs – its parameters are derived
from fitting an IV curve at STC conditions or from datasheet values (Isc, Vmp, Imp and Voc). Assumptions are made
on how Io, Rseries and Rshunt vary with irradiance (G) and temperature (T) – these don’t always give the correct low
light and temperature coefficients (as measured to IEC standards) resulting in an incorrect prediction of energy
performance. This work features a “Variable Coefficient 1-diode model” (VC1D) where parameters can change with
irradiance, temperature and voltage in different ways in an attempt to find the minimum discrepancy with measured
IV data by using the Loss Factor Model (LFM) methodology to compare IV curve fits. Initial results for CdTe are
better for the VC1D with nRsc, nRoc and nVoc but slightly worse for nVmp than the standard 1-diode model
program. It appears as if there are discrepancies between the predicted 1-diode model and IV measurements between
Vmp and Voc – further changes to the VC1D should enable these to be found using LFM coefficients and errors in
performance prediction minimised.

Such a curve is hyperelliptic over the algebraic closure of Q, but may not have a hyperelliptic model of the usual form over Q. We describe an algorithm that computes the local zeta functions of C at all odd primes of good reduction up to a prescribed bound N. The algorithm relies on an adaptation of the "accumulating remainder tree" to matrices with entries in a quadratic field. We report on an implementation, and compare its performance to previous algorithms for the ordinary hyperelliptic case.

description: We revive the historically first dark matter model based on neutrinos, but with an additional assumption that neutrinos might exist in tachyonic almost sterile states. To this end, we propose a group-theoretical algorithm for the description of tachyons. The key point is that we employ a distinct tachyon Lorentz group with new (superluminal) parametrization which does not lead to violation of causality and unitarity. Our dark matter model represents effectively scalar tachyonic neutrino-antineutrino conglomerate. Distributed all over the universe, such fluid behaves as stable isothermal/stiff medium which produces somewhat denser regions (`halos') around galaxies and clusters. To avoid the central singularity inherent to the isothermal profile, we apply a special smoothing algorithm which yields density distributions and rotation curves consistent with observational data.

description: The climatic conditions play an important role for a degradation mechanism of photovoltaic modules
known as potential induced degradation (PID). The influence of ambient humidity, precipitation and temperature on
the leakage current has been investigated with high voltage stress in two different climate regions. This work focusses
on one of them (Freiburg, Germany). For this test site, rain seems to have a large impact as it establishes a conductive
layer that leads to a high leakage current. A temperature dependency of the leakage current, which has already been
reported for indoor tests, was found as well.

description: The estimation of a photovoltaic module’s electrical characteristics under random irradiances and temperatures is essential to forecast precisely the energy production of a PV power plant. In order to determine these electrical characteristics, a two-diode equivalent circuit model is generally used.  The five parameters required to run the model are extracted from experimental I-V characteristic curves measured under specific conditions of irradiance and temperature.
In this paper, the investigation into an improved method based on Matlab for the extraction of the parameters of the two-diode equivalent circuit is presented. First, based on I-V curves measured at EDF R&D’s indoor test facilities, sets of parameters were extracted for PV modules of different technologies (thin films and crystalline silicon) using an improved curve fitting procedure and compared to existing extraction methods. Implementing these parameters, characteristic I-V curves were generated and compared to measurements under various conditions of irradiance/temperature. Then, considering the limits of the method that consists in using  a single set of parameters extracted under standard test conditions (STC) for the generation of  all characteristic I-V curves under various conditions of irradiance/temperature, investigations were carried out to improve the accuracy of the method.
Using I-V curves measured under various conditions of irradiance (100 to 1200 W/m²) and temperature (5 to 75°C), a single set of 11 parameters was extracted and compared to experimental data.
The results presented in this paper show improved accuracy using this new method especially for thin film panels. Therefore, this method will be implemented in our PV simulation tool in Dymola and compared to experimental data collected at EDF R&D’s outdoor test facilities.

as the threshold of the minimum requirements for PV modules to access to the international markets. However, the
PV modules work in various conditions such as in coastal areas, livestock farming, even in the desert areas, which
will seriously affect their lifetime. TÜV NORD, therefore, intends to simulate the dust and sand environment

description: The potential induced degradation (PID) of solar modules is a degradation effect which is recently
intensely investigated. With a potential of the solar cells relative to the grounded module frame, a leakage current is
observed, which depends on the temperature, humidity, voltage and time. With solar cells susceptible to PID, this
leakage current is related to a reversible degradation of the solar module power. All investigations up to now were
restricted to an external voltage of 1,000V. In this contribution, a high voltage PID tester is presented, which enables
us to apply external voltages on solar modules up to 20,000V while measuring very low leakage currents. We
investigated PID, time and voltage dependencies of the leakage current and the electrostatic field distribution of solar
modules in this extended voltage range.

description: We study the differences in the heavy ion composition of solar energetic particle (SEP) events between solar cycles 23 and 24. We have surveyed the SOHO/ERNE heavy ion data from the beginning of solar cycle 23 until the end of June 2015, that is, well into the declining phase of cycle 24. We used this long observation period to study the properties of heavy ions (from C to Fe) and to compare the two solar cycles in this respect. We surveyed the data for SEP events with enhancements in the Fe/C and Fe/O intensity ratios in the energy range 5-15 MeV per nucleon, and associated the events with solar flare and coronal mass ejections (CME) when possible. We studied the properties of heavy ions in these events and compared the average relative abundances of heavy ions between the two solar cycles. We found that fewer days had C and O intensities higher than ~10$^{-3}$ cm$^{-2}$sr$^{-1}$s$^{-1}$(MeVn$^{-1}$)$^{-1}$ during solar cycle 24 than during cycle 23. For Fe this difference was clear even at lower intensities. We also found that fewer days had Fe/(C+O) > 0.183 during cycle 24. We identified 86 SEP events with at least one Fe-rich day, 65 of which occurred during cycle 23 and only 21 during cycle 24. We found that impulsive events have been almost completely absent during cycle 24. Mean abundances of heavy ions in the events were found to be significantly lower during cycle 24 than in cycle 23. Our results reflect the reduced solar activity in cycle 24 and indicate lower efficiency of particle acceleration processes for both gradual and impulsive SEP events in cycle 24.

description: The value of Science, Technology, Engineering, Arts and Mathematics (STEAM) education, for STEM subjects and for developing the outcomes desired of a broader education, has seen significant interest in recent years. In the UK educational pathways into engineering are limited and engineering is rarely mentioned in the curriculum. Its closest partner, Design Technology, is typically under-resourced, especially in primary schools. However, the perceived value of STEAM in primary education has led to a range of different initiatives which have made this a fertile testbed for new approaches; approaches which will, over the coming decade, filter through all phases of education. Critically, STEAM has been identified, through its fusion with the arts, as fostering creative thinking in ways useful to STEM, particularly engineering. Additionally, it is argued that STEAM, if implemented early enough, can diversify the range of individuals considering careers in engineering. We draw on a five-year, primary education arts-engineering project which showed the efficacy of this inquiry-based STEAM approach in developing confident, creative learners, who felt they had agency in their learning, and a further two-year project working with teachers to design innovative art-engineering schemes of work following this model. The research explores the views of the engineers/designers, teachers, artists and pupils. The model developed from the research, the Trowsdale Art-Making Model for Education, has been tested by teachers as a practical approach to designing more embodied and inquiry-based curricula and pedagogies. The engineers identified this as critical in fostering children’s interest for and their ability in engineering

description: A problem which has troubled PV module manufacturers and end users for some time is how modules
can occasionally operate abnormally in the field, but when returned laboratory test as operating normally. In the field
it can occur that an inverter will protectively shut down due to a large leakage current, either in early morning or
rainy days. In such cases low wet insulation resistance of the PV module appears likely, however when returned to
the laboratory and tested as per international standards (e.g.: IEC6121561730-2, UL1703), the module is found to
still meet specification. The protection of inverters is also set properly according to applicable standards. This work
investigates the root cause of this issue, presenting the difference between standard insulation tests and actual field
operation.
This work investigates the influence in dry and wet insulation resistance of PV modules with respect to module
temperature, relative humidity, illumination etc. We find the insulation resistance reduces dramatically with
increasing module temperature. If module temperature increases to 60°C the insulation resistance reduces to
approximately 10% of the value measured at 25°C. Standards also require relative humidity not to exceed 75%,
however it is common in many parts of the globe for relative humidity to exceed 75% on many days throughout the
year. This therefore raises the question about how insulation resistance changes if relative humidity exceeds 75%. We
find the reduction in insulation resistant to be as great as 50% at 90%R.H. In closing, this paper suggests some
extended insulation resistance tests beyond international valid standards, leading to increased confidence in field
operation.

description: The threshold model has been widely adopted as a classic model for studying contagion processes on social networks. We consider asymmetric individual interactions in social networks and introduce a persuasion mechanism into the threshold model. Specifically, we study a combination of adoption and persuasion in cascading processes on complex networks. It is found that with the introduction of the persuasion mechanism, the system may become more vulnerable to global cascades, and the effects of persuasion tend to be more significant in heterogeneous networks than those in homogeneous networks: a comparison between heterogeneous and homogeneous networks shows that under weak persuasion, heterogeneous networks tend to be more robust against random shocks than homogeneous networks; whereas under strong persuasion, homogeneous networks are more stable. Finally, we study the effects of adoption and persuasion threshold heterogeneity on systemic stability. Though both heterogeneities give rise to global cascades, the adoption heterogeneity has an overwhelmingly stronger impact than the persuasion heterogeneity when the network connectivity is sufficiently dense.

description: By the end of 2012, the total PV module installation reached 100GW worldwide. The long term
reliability of modules has become more and more important. In this study, we report our investigation on
how to prevent module potential induced degradation (PID) by optimizing PV cell fabrication process. PID
is a type of module performance degradation when a voltage potential is applied to the module. PID free has
become one of the acceptance criteria from our customers. Regarding PID mechanisms, numerous
publications on cell process and module process are available. However, none of them focuses on modules
made of ion implanted c-Si cells. From our study, we have seen the different PID performance between
modules made with conventional POCl3 diffused cells, modified POCl3 diffused cells and ion implanted
cells. The advantages of ion implanted cells for PID free module performance is clearly shown. Ion
implantation technology for PV cell manufacturing was first introduced by Applied Materials in July 2010,
and Astronergy (Chint Solar) adopted Solion ion implantation technology in 2011. In this paper, we present
cell data, module data and PID test data of modules made of cells from different processes.

description: Ethylene vinyl-acetate (EVA) is a commonly used encapsulation material in the PV industry. Although
EVA degrades under various climatic conditions forming acetic acid, its relatively low price and missing experience
with alternative materials makes it the predominant choice for encapsulation material.
Chemical reactions, which occur during extended damp-heat (DH) conditions (90 °C/85 % r.h.) between the
degradation by-products of EVA and other involved components like e.g. the metallic compounds or the glass of the
metallisation, may result in metallisation corrosion and in isolated areas of the cell, visible in the electroluminescence
images. To evaluate the actually affected components and accelerating conditions to this phenomenon, several
parameters of the laminate design, such as number of bus bars (two or three) or the distance from the bus bar to the
glass and the back sheet material (TPT, TPAT, PA) were varied. The produced laminates were then exposed under
extended DH conditions to reveal the accelerating factors for the metallisation corrosion. In addition to this
preliminary work, the herewith presented study of X-ray investigations (X-ray diffraction and EDX spectroscopy
studies) were carried out on the metallisation and the degradation products.

description: Dans cet article est présentée une recherche-intervention en contexte académique français. L’objet est d’exposer, à partir du concept d’ » objet-frontière » (Star, 2010 ; Trompette & Vinck, 2009), comment ont été co-constitués trois objets d’évaluation singuliers et leurs référents d’évaluation. Notre hypothèse est que le concept d’objet-frontière d’évaluation peut servir à observer dans la « co-constitution référentielle dynamique » (Mottier Lopez, 2022 ; Mottier Lopez & Dechamboux, 2017) l’identification de l’objet d’évaluation commun en conservant les tensions et disparités de ses significations. Dans le cadre de cette recherche, trois objets-frontières d’évaluation ont été identifiés par les pilotes territoriaux d’une action publique éducative réformant la formation continue des professeur·es du premier degré : la réussite du dispositif de formation, la place du directeur d’école dans son pilotage et la professionnalité du formateur de ce dispositif. La conclusion présente les limites identifiées et les perspectives pour la deuxième année de recherche à venir.
