description: Two new ON supergiant spectra (bringing the total known to seven) and one new ONn giant (total of this class now eight) are presented; they have been discovered by the Galactic O-Star Spectroscopic Survey. These rare objects represent extremes in the mixing of CNO-cycled material to the surfaces of evolved, late-O stars, by uncertain mechanisms in the first category but likely by rotation in the second. The two supergiants are at the hot edge of the class, which is a selection effect from the behavior of defining N III and C III absorption blends, related to the tendency toward emission (Of effect) in the former. An additional N/C criterion first proposed by Bisiacchi et al. is discussed as a means to alleviate that effect, and it is relevant to the two new objects. The entire ON supergiant class is discussed; they display a fascinating diversity of detail undoubtedly related to the complexities of their extended atmospheres and winds that are sensitive to small differences in physical parameters, as well as to binary effects in some cases. Serendipitously, we have found significant variability in the spectrum of a little-known hypergiant with normal N, C spectra selected as a comparison for the anomalous objects. In contrast to the supergiants, the ONn spectra are virtual (nitrogen)-carbon copies of one another except for the degrees of line broadening, which emphasizes their probable unique origin and hence amenability to definitive astrophysical interpretation.

description: We report the results of our follow-up campaign of the supernova impostor PSN J09132750+7627410, based on optical data covering $\sim250\,\rm{d}$. From the beginning, the transient shows prominent narrow Balmer lines with P-Cygni profiles, with a blue-shifted absorption component becoming more prominent with time. Along the $\sim3\,\rm{months}$ of the spectroscopic monitoring, broad components are never detected in the hydrogen lines, suggesting that these features are produced in slowly expanding material. The transient reaches an absolute magnitude $M_r=-13.60\pm0.19\,\rm{mag}$ at maximum, a typical luminosity for supernova impostors. Amateur astronomers provided $\sim4\,\rm{years}$ of archival observations of the host galaxy, NGC 2748. The detection of the quiescent progenitor star in archival images obtained with the Hubble Space Telescope suggests it to be an $18-20$\msun white-yellow supergiant.

description: A bismuth oxyiodide photocatalyst having coexistent iodine deficient phases viz. Bi4O5I2 and Bi5O7I was prepared by using a solvothermal method followed by calcination process. This has been used for the degradation of model perfluoroalkyl acids such as perfluorooctanoic acid at low concentrations (1 ppm) under simulated solar light irradiation. 94% PFOA degradation with a rate constant of 1.7 h− 1 and 65% defluorination of PFOA have been achieved following 2 h of photocatalysis. The degradation of PFOA happened by the parallel direct redox reactions with high energy photoexcited electrons at the conduction band, electrons in iodine vacancies and superoxide radicals. The degradation intermediates were analyzed by electrospray ionization-mass spectrometry in the negative mode. The catalyst was converted to a more iodine deficient Bi5O7I phase during photocatalysis following creation of iodine vacancies, some of which were compensated by the fluoride ions released from degraded PFOA
Photoionization Modeling of the Low Luminosity Seyfert 1 Nucleus in NGC 3516

description: Spectroscopic observations of the low luminosity Seyfert 1 nucleus in NGC 3516 obtained with the Hubble Space Telescope show that the visible spectrum is dominated by the Balmer emission lines of Hydrogen (H) and a continuum luminosity that rises into the UV. The anomalous H$α$/H$β$ emission line ratio, the Balmer emission line luminosity and the distinctive shape observed for the H$α$ emission line profile serve as important constraints in any photoionization model aimed at explaining the visible emission line spectrum of NGC 3516. Photoionization modeling using Cloudy demonstrates that the central UV-X-ray source is able to completely ionize the H gas in between the Balmer and dust reverberation radii if the electron density is ${\le}$ 3 ${\times}$ 10${^7}$ cm${^{-3}}$ throughout. Thus, according to this model the region responsible for producing the visible H lines is a dust free shell of ionized H gas. Interestingly, the model predicts a rapid rise in the electron temperature as the central UV-X-ray source is approached, mirrored by an equally precipitous decrease in the Balmer line emissivity that coincides with the Balmer reverberation radius, providing a natural explanation for the finite width observed for the H Balmer lines. Collectively, the merit of the model is that it explains the relative intensities of the three brightest Balmer lines, and the shape of the H$α$ emission line profile. However, questions remain concerning the unusually weak forbidden lines that can not be addressed using Cloudy due to limitations with the code.

description: To forecast the photovoltaic (PV) power production, global horizontal irradiance (GHI) obtained from a
numerical weather prediction (NWP) model are useful. In Japan, the Japan meteorological Agency (JMA) has been
developed an operational NWP (that is, meso-scale model, MSM) with the horizontal grid spacing of 5km. In this
study, the range of forecast errors of the GHI is investigated on seasonal and annual changes. In addition, we compared
forecast errors between a station and a relatively large area of the Kanto region in the main island, Japan.
Validation results of hourly GHI forecasts showed that overestimations of GHI forecasts were found in relatively
higher clear sky conditions while underestimations of those were found in relatively lower clear sky conditions. In
clear sky or rainy conditions, ranges of forecast errors tend to be relatively smaller, suggesting that the GHI values
are well forecasted in these conditions. Seasonal analysis of the range of forecast errors showed that underestimations
of the GHI were significant in summer at a point station. From results for a relatively large area of the TEPCO (Tokyo
Electric Power Company) region, we confirmed that ranges of forecast errors tended to be decreased by a spatial-
smoothing effect.

description: In recent years there has been a paradigm shift from centralised to geographically distributed resources. Individual entities are no longer able to host or afford the necessary expertise in-house, and, as a consequence, society increasingly relies on widespread collaborations. Although such collaborations are now the norm for scientific projects, more technical structures providing support to a distributed scientific community without direct financial or other material benefits are scarce. The network of European ALMA Regional Centre (ARC) nodes is an example of such an internationally distributed user support network. It is an organised effort to provide the European ALMA user community with uniform expert support to enable optimal usage and scientific output of the ALMA facility. The network model for the European ARC nodes is described in terms of its organisation, communication strategies and user support.

description: This course on the presence of cathedrals in France is a part of a course entitled "Culture and society in France" given at Stockholm University (French, level I) The cathedral is perceived as a colossal architectural element in the landscape often emerging as a literary motif (Hugo, Proust...). It refers to a thousand-year-old time and also appears as a metaphor for a discourse on civilizations. During the fire of Notre-Dame de Paris on April 15, 2019, this metaphor was even reused in the political discourse by touching on emotions (How should we rebuild the nation? Can we create similar buildings nowadays?). This lesson is based upon a pedagogical project supported by Stockholm University (Årets lärare 2021).

description: The deserts are suitable areas for large solar power plants, because of abundant sunshine and enormous
land. Both are important factors for solar power plants. However, not all desert areas are suitable for installation, for
example sand dunes, water, and cliffs. But there is one kind of desert area which has flat and hard ground. It is gravel
desert which can be a suitable location. Therefore, the authors proposed a method to identify flat desert areas for large
solar power plants using satellite images. It consists of three criteria; (1) Mountainous classification to find cliffs and
sand dunes, (2) Ground cover classification by maximum likelihood estimation, and (3) Vegetation classification to
find lower vegetation area. With the criterion, a land suitability index map; a detailed map of flat areas, of the Sahara
desert had been computed. In this paper, the criterion has been refined in order to evaluate higher vegetation regions
which are located at the fringes of desert. The revised criterion was applied to the Sahara desert, and the land
suitability index map has been computed.

description: Within a large scale grid-connected PV plant irradiance enhancements (IE) and irradiance variability
(IV) can lead to a difference for irradiance values of up to 1,000 W/m² at the same time. Using common simulation
methods these effects aren’t visible. Considering spatial irradiance values in high temporal resolution allows an
optimization of the performance of PV plants or an analysis of the safety aspects of PV systems. The combination of a
sampling rate in high temporal resolution of minutes or seconds, to display IE and IV, with the 3D- Solar Irradiance
Modelling (3D-SIM) enables to assign different irradiance values to every single module of a PV plant. This modelling of
PV plants is very accurate and authentic to the operational behaviour of the PV plants. These results can be used to
compare e.g. different interconnection of the modules, different maximum power point tracking (MPPT) methods and
layouts of PV plants. The main focus of this study is to create generally accepted instructions for the performance
optimised dimensioning of a PV plant particularly for the sizing ratio. The same issues are possible for distribution
networks, so several spatially distributed PV plants can be simulated simultaneously and feed-in effects and grid
characteristics can be considered.
Disorder-Induced Entanglement in Spin Ice Pyrochlores

description: We propose that in a certain class of magnetic materials, known as non-Kramers 'spin ice,' disorder induces quantum entanglement. Instead of driving glassy behavior, disorder provokes quantum superpositions of spins throughout the system, and engenders an associated emergent gauge structure and set of fractional excitations. More precisely, disorder transforms a classical phase governed by a large entropy, classical spin ice, into a quantum spin liquid governed by entanglement. As the degree of disorder is increased, the system transitions between (i) a "regular" Coulombic spin liquid, (ii) a phase known as "Mott glass," which contains rare gapless regions in real space, but whose behavior on long length scales is only modified quantitatively, and (iii) a true glassy phase for random distributions with large width or large mean amplitude.

description: One of the prevalent learning tasks involving images is content-based image classification. This is a difficult task especially because the low-level features used to digitally describe images usually capture little information about the semantics of the images. In this paper, we tackle this difficulty by enriching the semantic content of the image representation by using external knowledge. The underlying hypothesis of our work is that creating a more semantically rich representation for images would yield higher machine learning performances, without the need to modify the learning algorithms themselves. The external semantic information is presented under the form of non-positional image labels, therefore positioning our work in a weakly supervised context. Two approaches are proposed: the first one leverages the labels into the visual vocabulary construction algorithm, the result being dedicated visual vocabularies. The second approach adds a filtering phase as a pre-processing of the vocabulary construction. Known positive and known negative sets are constructed and features that are unlikely to be associated with the objects denoted by the labels are filtered. We apply our proposition to the task of content-based image classification and we show that semantically enriching the image representation yields higher classification performances than the baseline representation.

description: PV module qualification tests carried out in environmental chamber act as good screening tests to
prevent infant mortality of field deployed PV modules. However they don't guarantee long term durability of PV
modules, neither do they provide any quantifiable information about it. In order to gain insight about reliability of
modules over a 25 year lifetime, it is necessary to study the modes and mechanisms of failure from the outdoor test
data. Outdoor testing exposes the modules to real world conditions and several combinations of environmental
stresses that is not possible with accelerated testing in chamber. A comparison of accelerated testing and outdoor
testing is presented with an example of outdoor high voltage testing where slight acceleration can be introduced while
still exposing the module to the outdoor conditions. Outdoor high voltage bias testing carried out in Florida's hot and
humid climate can yield desired results in a reasonable time frame. The outdoor test results can help in deciphering
failure modes observed in field deployed modules and also increasing the confidence levels of accelerated test results.
Investment in outdoor testing is can help minimize the risk of heavy financial damages such as in warranty
replacements.

description: Soiling impact on photovoltaic (PV) module performance in the outdoor has been investigated through
utilizing an innovative 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
December 2012, one DDS with copper indium gallium diselenide (CIGS) thin-film PV modules has been set up in a
utility-scale PV power plant in Thailand. Daily soiling effect on performance loss has been observed with significant
impact up to 30%, which may lead to thousands of kWh loss in utility scale PV power plant and in consequence
jeopardize return of investment for investors. Furthermore, CIGS outdoor performance was examined by system
loss methodology which was proposed in 27th EUPVSEC, Frankfurt, Germany. Utilizing the proposed methodology
with capability in distinguishing soiling impact by DDS, the authors have successfully evaluated the outdoor
performance of CIGS modules, including the module power gain from the light soaking effect.

Monitoring and analysing the scientific return can help to modify and optimise operations and adapt to the changing needs of scientific research. The methodology that we have developed to monitor the scientific productivity of the ALMA Observatory, as well as the first results, are described. We focus on the outcome of the first cycle (Cycle 0) of ALMA Early Science operations. Despite the fact that only two years have passed since the completion of Cycle 0 and operations have already changed substantially, this analysisconfirms the effectiveness of the underlying concepts. We find that ALMA is fulfilling its promise as a transformational facility for the observation of the Universe in the submillimetre.

description: Uncertainties in the calibration of PV devices affect the power rating of modules and thus their value.
The expanded measurement uncertainty in Pmax of modules at state-of-art indoor calibration facilities is between 1.6-
3.85% based on conventional Si technologies. The uncertainties of TF technologies are agreed to be higher. The
contributions from different uncertainty sources are combined according to the GUM Uncertainty Framework. The
Framework has the limitation of considering only the mean and standard deviation of symmetric distributions. This
paper advocates the use of the Monte Carlo (MC) method for calculating the overall uncertainty of module calibration
that is specific to the device-under-test and the measuring setup. Since the MC method retains all the information
from the input quantities, more comprehensive probability density functions can be assigned to the main contributors.
Recognised systematic effects can be accounted for by assigning asymmetric distributions to given contributions
eliminating the need for correction. The use of the MC method for the total uncertainty calculation allows for a more
detailed estimation of the input influences and their understanding and minimisation. In the simulated case study this
led to reduction in uncertainty from ±2.5% in Isc to [+1.93%:-1.97%] for a 95% coverage interval.

description: A summary of number structure scaling is followed by a description of the effects of number scaling in nonrelativistic quantum mechanics. The description extends earlier work to include the effects on the states of two or more interacting particles. Emphasis is placed on the effects on entangled states. The resulting scaling field is generalized to describe the effects on these states. It is also seen that one can use fiber bundles with fibers associated with single locations of the underlying space to describe the effects of scaling on arbitrary numbers of particles.

description: Cross-plane superlattices composed of nanoscale layers of alternating potential wells and barriers have attracted great attention for their potential to provide thermoelectric power factor improvements and higher ZT figure of merit. Previous theoretical works have shown that the presence of optimized potential barriers could provide improvements to the Seebeck coefficient through carrier energy filtering, which improves the power factor by up to 40%. However, experimental corroboration of this prediction has been extremely scant. In this work, we employ quantum mechanical electronic transport simulations to outline the detrimental effects of random variation, imperfections and nonoptimal barrier shapes in a superlattice geometry on these predicted power factor improvements. Thus we aim to assess either the robustness or the fragility of these theoretical gains in the face of the types of variation one would find in real material systems. We show that these power factor improvements are relatively robust against: overly thick barriers, diffusion of barriers into the body of the wells, and random fluctuations in barrier spacing and width. However, notably, we discover that extremely thin barriers and random fluctuation in barrier heights by as little as 10% is sufficient to entirely destroy any power factor benefits of the optimized geometry. Our results could provide performance optimization routes for nanostructured thermoelectrics and elucidate the reasons why significant power factor improvements are not commonly realized in superlattices, despite theoretical predictions.

description: Despite all PV materials are influenced by the spectral irradiance, thin film PV modules are especially
sensitive to it. Indeed, the outdoor performance of thin film technologies is not so satisfactorily understood as that of
crystalline silicon due to spectral issues. Thus, the spectral factor is a useful and meaningful index to quantify spectral
gains or losses that a PV module may experience under the actual spectrum when compared to the standard
AM 1.5-G. This work is mainly aimed at looking into the dependence of the spectral factor of four modules
representative of four PV technologies –hydrogenated amorphous silicon (a-Si:H), cadmium telluride (CdTe), copper
indium diselenide (CIS) and monocrystalline silicon (m-Si)- on the average photon energy, an index that
characterizes the spectrum shape. PV modules made of a-Si:H, CdTe, CIS and m-Si are ordered from highest to
lowest dependence of the reciprocal of the spectral factor on the average photon energy.

Due to the anisotropy of the dipole-dipole interactions, the dipole-driven collapse induced by soft excitations is compensated by the repulsive Lee-Huang-Yang contribution resulting from quantum fluctuations of hard excitations, in a similar mechanism as that recently proposed for Bose-Bose mixtures. The arrested collapse results in self-bound filament-like droplets, providing an explanation to recent dysprosium experiments. Arrested instability and droplet formation are novel general features directly linked to the nature of the dipole-dipole interactions, and should hence play an important role in all future experiments with strongly dipolar gases.

description: For evaluation of the characteristics of photovoltaic cells, the solar simulator is adjusted to 1 kW/m²
utilizing a reference cell. A Spectral Reference Cell method that can be used for adjustment of solar simulator
intensity for testing photovoltaic cells without using specific physical reference cells is proposed.
Furthermore, this method is expanded to non-linear photovoltaic cells by using DSR (Differential Spectral
Responsivity) method (IEC 60904-4) that can measure using the absolute spectral responsivity at various irradiance
levels. Utilizing this method, adjustment performance of solar simulator’s intensity for various spectral responses
within ±3% error for 1sun to 0.01sun was achieved by our instrument.
The Spectral Reference Cell Method could be very useful in the development stage of photovoltaic cells, especially
for non-linear cells.

description: The photovoltaic cells (PV) are commonly used as global radiation measurement device, even though
when it has been proved that there are significant differences with respect to using pyranometers. The dirt deposited
on the surface of the PV is one of the most influential factors in the measurement of the solar radiation. In this work
we have made experimental measurements with four identical cells, two cleans and two dirties with different soil
density (0.2 g/m2, 0.4 g/m2, 0.8 g/m2, 1.2 g/m2 and 1.5 g/m2) and different size particles (< 125 μm) comparing the
results and obtaining a correlation between the density of the dust and the difference between the measured irradiance
for clean and dirty cells for each particle size.

description: CEA and Météo France have joined their skills to demonstrate the best implementation of the CEA’s
MotherPV method, which predicts the electrical production of photovoltaic modules by a standardized
characterization of the modules and by specific environmental resource datasets, called Photovoltaic Potential
datasets. During more than three years, the short-circuit current and the temperature of a mini multicrystalline silicon
module exposed at the radiometric centre of Carpentras have been measured every second and recorded every minute.
In order to provide more realistic datasets, the recorded data have been monthly corrected using long term (11 years)
horizontal irradiation data, thanks to an empirical translation model of the monthly irradiation from horizontal to
tilted planes. A Photovoltaic Typical Year has been defined and the Module Performance Panel summarizing the
module performance has been calculated. The procedure to assess a Photovoltaic Typical Year and the dataset itself
could be useful for the future third part of the in-progress IEC 61853 standard.

description: Massive stars that have been ejected from their parent cluster and supersonically sailing away through the interstellar medium (ISM) are classified as exiled. They generate circumstellar bow shock nebulae that can be observed. We present two-dimensional, axisymmetric hydrodynamical simulations of a representative sample of stellar wind bow shocks from Galactic OB stars in an ambient medium of densities ranging from n_ISM=0.01 up to 10.0/cm3. Independently of their location in the Galaxy, we confirm that the infrared is the most appropriated waveband to search for bow shocks from massive stars. Their spectral energy distribution is the convenient tool to analyze them since their emission does not depend on the temporary effects which could affect unstable, thin-shelled bow shocks. Our numerical models of Galactic bow shocks generated by high-mass (~40 Mo) runaway stars yield H$α$ fluxes which could be observed by facilities such as the SuperCOSMOS H-Alpha Survey. The brightest bow shock nebulae are produced in the denser regions of the ISM. We predict that bow shocks in the field observed at Ha by means of Rayleigh-sensitive facilities are formed around stars of initial mass larger than about 20 Mo. Our models of bow shocks from OB stars have the emission maximum in the wavelength range 3 <= lambda <= 50 micrometer which can be up to several orders of magnitude brighter than the runaway stars themselves, particularly for stars of initial mass larger than 20 Mo.

description: Since solar cells are spectrally selective, photovoltaic modules are affected by the spectral distribution
of the in-plane irradiation. This is in turn dependent on the radiative transfer through the atmosphere.
Many parameters are used to characterize the quality of spectral distribution, i.e. its balance towards low rather than
high wavelengths. They are based on measured or modeled solar spectra, and may or not require the measurement of
the module spectral response.
This paper presents a method for the evaluation of spectral effect through the use of the average wavelength of
modeled spectra. It results therefore useful when no measured spectral data is available, and does not require the
measurement of the module spectral response.
The integral value of modeled spectral distribution is first validated through comparison with measured irradiance.
The average wavelength is then used to assess the spectral effect on the performance of different PV technologies
installed at Airport Bolzano Dolomiti (ABD) test facility and monitored by EURAC: polycrystalline silicon (pc-Si),
single junction amorphous silicon (a-Si), micromorph silicon (a-Si/μc-Si), Cadmium Telluride (CdTe) and Copper
Indium Gallium Selenide (CIGS). Daily, seasonal and meteorology-related variability of the parameter is also
assessed.
Oscillation: The Key For Understanding Strange Radio Behaviors Of AXP/SGRs

description: We suggest stellar oscillations are responsible for the strange radio behaviors of Anomalous X-ray pulsars and soft Gamma-ray repeaters (AXP/SGRs), within the framework of both solid quark star model and magnetar model. In solid quark star model, the extra voltage provided by oscillations activates the star from under death line to above death line. In magnetar model, oscillations enlarge the radio beam so that increase the possibility to detect it. Later radio emission decays and vanishes as oscillations damp.

On the precision of a data-driven estimate of the pseudoscalar-pole contribution to hadronic light-by-light scattering in the muon g-2

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The evaluation of the numerically dominant pseudoscalar-pole contribution to hadronic light-by-light scattering in the muon g-2 involves the pseudoscalar-photon transition form factor F_{P gamma^* gamma^*}(-Q_1^2, -Q_2^2) with P = pi^0, eta, eta^\prime and, in general, two off-shell photons with spacelike momenta Q_{1,2}^2. We determine which regions of photon momenta give the main contribution for hadronic light-by-light scattering. Furthermore, we analyze how the precision of future measurements of the single- and double-virtual form factor impacts the precision of a data-driven estimate of this contribution to hadronic light-by-light scattering.

description: We study, numerically and experimentally, the momentum distribution of atoms cooled in optical lattices. Using semi-classical simulations, we show that this distribution is bimodal, made up of a central feature corresponding to "cold", trapped atoms, with tails of "hot", untrapped atoms, and that this holds true also for very shallow potentials. Careful analysis of the distribution of high-momentum untrapped atoms, both from simulations and experiments, shows that the tails of the distribution does not follow a normal law, hinting at a power-law distribution and non-ergodic behavior. We also revisit the phenomenon of décrochage, the potential depth below which the temperature of the atoms starts increasing.

description: From high resolution (R = 45,000), high signal-to-noise (S/N > 400) spectra gathered with the Immersion Grating Infrared Spectrograph (IGRINS) in the H and K photometric bands, we have derived elemental abundances of two bright, well-known metal-poor halo stars: the red giant HD 122563 and the subgiant HD 140283. Since these stars have metallicities approaching [Fe/H] = -3, their absorption features are generally very weak. Neutral-species lines of Mg, Si, S and Ca are detectable, as well as those of the light odd-Z elements Na and Al. The derived IR-based abundances agree with those obtained from optical-wavelength spectra. For Mg and Si the abundances from the infrared transitions are improvements to those derived from shorter wavelength data. Many useful OH and CO lines can be detected in the IGRINS HD 122563 spectrum, from which derived O and C abundances are consistent to those obtained from the traditional [O I] and CH features. IGRINS high resolutions H- and K-band spectroscopy offers promising ways to determine more reliable abundances for additional metal-poor stars whose optical features are either not detectable, or too weak, or are based on lines with analytical difficulties.

description: This work shows the possibility to optimize time and effort for quality and reliability tests on PV modules
based on systematic evaluation of existing test experiences. Exemplarily, a statistical study on changes in the
electroluminescence image and module output power due to the common thermal cycling (acc. point 10.11, IEC 61215)
after 200 and 400 cycles is shown. Above all, the great benefit of this data is the comparability of exactly determined
characteristics before and after stress tests of a large scale of different modules.

description: We study random eigenvalue problems in the context of spectral stochastic finite elements. In particular, given a parameter-dependent, symmetric positive-definite matrix operator, we explore the performance of algorithms for computing its eigenvalues and eigenvectors represented using polynomial chaos expansions. We formulate a version of stochastic inverse subspace iteration, which is based on the stochastic Galerkin finite element method, and we compare its accuracy with that of Monte Carlo and stochastic collocation methods. The coefficients of the eigenvalue expansions are computed from a stochastic Rayleigh quotient. Our approach allows the computation of interior eigenvalues by deflation methods, and we can also compute the coefficients of multiple eigenvectors using a stochastic variant of the modified Gram-Schmidt process. The effectiveness of the methods is illustrated by numerical experiments on benchmark problems arising from vibration analysis.
