description: We investigated the prospects for systematic searches of white dwarfs at low Galactic latitudes, using the VLT Survey Telescope (VST) H$α$ Photometric Survey of the Galactic plane and Bulge (VPHAS+). We targeted 17 white dwarf candidates along sightlines of known open clusters, aiming to identify potential cluster members. We confirmed all the 17 white dwarf candidates from blue/optical spectroscopy, and we suggest five of them to be likely cluster members. We estimated progenitor ages and masses for the candidate cluster members, and compared our findings to those for other cluster white dwarfs. A white dwarf in NGC 3532 is the most massive known cluster member (1.13 M$_{\odot}$), likely with an oxygen-neon core, for which we estimate an $8.8_{-4.3}^{+1.2}$ M$_{\odot}$ progenitor, close to the mass-divide between white dwarf and neutron star progenitors. A cluster member in Ruprecht 131 is a magnetic white dwarf, whose progenitor mass exceeded 2-3 M$_{\odot}$. We stress that wider searches, and improved cluster distances and ages derived from data of the ESA Gaia mission, will advance the understanding of the mass-loss processes for low- to intermediate-mass stars.

description: Dislocation free local SiGe-on-insulator (SGOI) virtual substrate is fabricated using lateral selective SiGe growth by reduced pressure chemical vapor deposition. The lateral selective SiGe growth is performed around a ∼1.25 μm square Si (001) pillar in a cavity formed by HCl vapor phase etching of Si at 850 °C from side of SiO2/Si mesa structure on buried oxide. Smooth root mean square roughness of SiGe surface of 0.14 nm, which is determined by interface roughness between the sacrificially etched Si and the SiO2 cap, is obtained. Uniform Ge content of ∼40% in the laterally grown SiGe is observed. In the Si pillar, tensile strain of ∼0.65% is found which could be due to thermal expansion difference between SiO2 and Si. In the SiGe, tensile strain of ∼1.4% along 〈010〉 direction, which is higher compared to that along 〈110〉 direction, is observed. The tensile strain is induced from both [110] and [−110] directions. Threading dislocations in the SiGe are located only ∼400 nm from Si pillar and stacking faults are running towards 〈110〉 directions, resulting in the formation of a wide dislocation-free area in SiGe along 〈010〉 due to horizontal aspect ratio trapping.

description: The luminescence of silicon has been used for many applications such as lifetime measurements and
defect characterization in multicrystalline silicon for solar cells. In this paper we demonstrate new applications of
luminescence spectroscopy for the characterization of multicrystalline silicon which are based on a very high spatial
resolution in the order of one μm. These applications are the detection of small metal precipitates, the qualitative
measurement of internal stress and X-ray Excited Optical Luminescence for correlating of X-ray fluorescence
measurements with the minority carrier diffusion length.
Quantifying uncertainty about global and regional economic impacts of climate change

description: The economic impacts of climate change are highly uncertain. Two of the most important uncertainties are the sensitivity of the climate system and the so-called damage functions, which relate climate change to economic damages and benefits. Despite broad awareness of these uncertainties, it is unclear which of them is most important, both on the global as well as the regional level. Here we apply different damage functions to data from climate models with vastly different climate sensitivities, and find that uncertainty in both climate sensitivity and economic damage per degree of warming are of similar importance for the global economic impact. Increasing the climate sensitivity or the sensitivity of the damage function both increases the economic damages globally. Yet, at the country-level the effect varies depending on the initial temperature as well as how much the country warms. Our findings emphasise the importance of including these uncertainties in estimates of future economic impacts, as they both are vital for the resulting impacts and thus policy implications.

description: Pre-breakdown mechanisms in semiconductors exhibit characteristic temperature dependences. Using
temperature-dependent lock-in thermography (LIT) measurements and electroluminescence imaging under reverse bias
we have found local regions with positive and with negative temperature coefficient (TC) of the breakdown current of
multicrystalline silicon solar cells. In some regions, the temperature coefficient changes sign (from negative to positive)
when going to higher temperatures. At low temperatures and for moderate reverse voltages, most pre-breakdown sites
show a negative temperature coefficient, whereas the total cell current increases with temperature. This contradiction is
resolved by rescaling the LIT images revealing that in the whole area of the cell a homogeneous reverse current flows,
which increases with temperature and thereby compensates the negative TC of the localized currents. Altogether, in
addition to the hard pre-breakdown (type III), the recombination-active defect-related soft pre-breakdown (type II) and
the early pre-breakdown (type I), two additional pre-breakdown phenomena have been identified.

description: Photovoltaic modules based on the relatively new thin film technology are gaining importance in the
photovoltaic market. Some of these modules are made of silicon, consisting of layers of amorphous silicon or
microcrystalline silicon. Other thin film PV modules are made of CIS, Cadmium Telluride (CdTe) or less frequently organic
compounds. The materials used in thin film technologies pose problems in terms of measuring how much power is generated
under standard test conditions (STC). This is due to the fact that the modules´ power rates could vary depending both on the
amount of time they have been exposed to the sun and on their history of sunlight exposure. So it is necessary to know the
previous periods of sunlight exposure in order to know the current state of the module.
It is necessary to determine an easily accomplishable testing method that ensures the repeatability of the measurements of the
power generated. This is essential because in order to have a reliable sample of the PV module population of a large PV
plant, a huge number of modules must be measured.
This paper shows different tests performed on different commercial thin film PV modules in order to find the best way to
obtain measurements. A correlation was tested between sun exposure and power measured. A method for obtaining indoor
measurements of these technologies that takes periods of sunlight exposure into account is proposed. Additionally,
temperature and irradiance coefficients were also determined for different technologies in order to obtain accurate
measurements.

description: Generative Adversarial Networks (GANs) currently achieve the state-of-the-art sound synthesis quality for pitched musical instruments using a 2-channel spectrogram representation consisting of log magnitude and instantaneous frequency (the "IFSpectrogram"). Many other synthesis systems use representations derived from the magnitude spectra, and then depend on a backend component to invert the output magnitude spectrograms that generally result in audible artefacts associated with the inversion process. However, for signals that have closely-spaced frequency components such as non-pitched and other noisy sounds, training the GAN on the 2-channel IFSpectrogram representation offers no advantage over the magnitude spectra based representations. In this paper, we propose that training GANs on single-channel magnitude spectra, and using the Phase Gradient Heap Integration (PGHI) inversion algorithm is a better comprehensive approach for audio synthesis modeling of diverse signals that include pitched, non-pitched, and dynamically complex sounds. We show that this method produces higher-quality output for wideband and noisy sounds, such as pops and chirps, compared to using the IFSpectrogram. Furthermore, the sound quality for pitched sounds is comparable to using the IFSpectrogram, even while using a simpler representation with half the memory requirements.

description: III-V concentrator photovoltaic systems attain high efficiency through the use of series connected
multi-junction solar cells. As these solar cells absorb over distinct bands over the solar spectrum, they have a more
complex response to real illumination conditions than conventional silicon solar cells. Estimates for annual energy
yield made assuming fixed reference spectra can vary by up to 15% depending on the assumptions made. Using a
detailed computer simulation, the behaviour of a 20-cell multi-junction concentrator system were simulated in 5
minute intervals over an entire year, accounting for changes in direct normal irradiance, humidity, temperature and
aerosol optical density. The simulation was compared with concentrator system monitoring data taken over the same
period and excellent agreement (within 2%) in the annual energy yield was obtained.

description: As the solar industry scales towards installation capacities
in the range of 30 to 50 gigawatts per year, SunPower has
begun to evaluate concentration in order to leverage cell
production capacity. SunPower is currently focusing on
research and development investments in low
concentration photovoltaic (LCPV) systems, which can
reduce capital expense per watt by up to 90% while
minimizing design changes in SunPower’s high efficiency
back contact solar cells. Herein, we demonstrate a linear
7X geometric, parabolic-section, single-axis concentration
photovoltaic system. We have installed an LCPV array at
the National Solar Thermal Test Facility at Sandia National
Labs in Albuquerque, New Mexico. Preliminary
performance data indicates a direct resource efficiency of
18.4% and a misalignment tolerance of ±1.25°.

description: Background: The RAPID N-STEMI trial investigated whether a very early invasive strategy (IS) improves clinical outcomes as compared to a standard of care strategy in higher-risk non-ST elevation acute coronary syndrome (NSTE-ACS). The study was terminated early due to the COVID-19 pandemic. The focus of this thesis pivoted to investigate the impact of COVID-19 on patients with acute coronary syndrome (ACS). Methods: A systematic review and meta-analysis of randomised-controlled trials that investigated timing of IS in NSTE-ACS was undertaken. Additionally, two multicentre observational studies examined the impact of COVID-19 on: 1) COVID-19 positive ACS patients undergoing invasive coronary angiography; 2) complex coronary artery disease patients who were treated with percutaneous coronary intervention (PCI) rather than coronary artery bypass grafting (CABG). Results: An early IS was not associated with a reduction in clinically significant hard endpoints (death and myocardial infarction) in unselected all-comer patients with NSTE-ACS. Additionally: 1) COVID-19 ACS patients present later, have increased in-hospital mortality and excess rates of cardiogenic shock as compared to a pre-COVID population. Adverse outcomes appear to be driven by delays in seeking medical care and timely reperfusion therapy. 2) PCI undertaken using contemporary techniques with high rates of intravascular imaging and calcium modification provides equivalent acute results to historical CABG reference data, and to PCI reference cohorts of lower complexity. Conclusions: The COVID-19 pandemic has had an unprecedented direct and indirect impact on patients with ACS. Future clinical research initiatives to better understand COVID-19 and the multiple mechanistic factors at play are essential.

description: Brain aneurysm detection in Time-Of-Flight Magnetic Resonance Angiography (TOF-MRA) has undergone drastic improvements with the advent of Deep Learning (DL). However, performances of supervised DL models heavily rely on the quantity of labeled samples, which are extremely costly to obtain. Here, we present a DL model for aneurysm detection that overcomes the issue with ''weak'' labels: oversized annotations which are considerably faster to create. Our weak labels resulted to be four times faster to generate than their voxel-wise counterparts. In addition, our model leverages prior anatomical knowledge by focusing only on plausible locations for aneurysm occurrence. We frst train and evaluate our model through cross-validation on an in-house TOF-MRA dataset comprising 284 subjects (170 females / 127 healthy controls / 157 patients with 198 aneurysms). On this dataset, our best model achieved a sensitivity of 83%, with False Positive (FP) rate of 0.8 per patient. To assess model generalizability, we then participated in a challenge for aneurysm detection with TOF-MRA data (93 patients, 20 controls, 125 aneurysms). On the public challenge, sensitivity was 68% (FP rate=2.5), ranking 4th/18 on the open leaderboard. We found no signifcant diference in sensitivity between aneurysm risk-of-rupture groups (p=0.75), locations (p=0.72), or sizes (p=0.15). Data, code and model weights are released under permissive licenses. We demonstrate that weak labels and anatomical knowledge can alleviate the necessity for prohibitively expensive voxel-wise annotations.

description: Topological Weyl semimetals (TWS) can be classified as type-I TWS, in which the density of states vanishes at the Weyl nodes, and type-II TWS where an electron and a hole pocket meet with finite density of states at the nodal energy. The dispersions of type-II Weyl nodes are tilted and break Lorentz invariance, allowing for physical properties distinct from those in a type-I TWS. We present minimal lattice models for both time-reversal-breaking and inversion-breaking type-II Weyl semimetals, and investigate their bulk properties and topological surface states. These lattice models capture the extended Fermi pockets and the connectivities of Fermi arcs. In addition to the Fermi arcs, which are topologically protected, we identify surface "track states" that arise out of the topological Fermi arc states at the transition from type-I to type-II with multiple Weyl nodes, and persist in the type-II TWS.

description: We study linear ill-posed inverse problems with noisy data in the framework of statistical learning. The corresponding linear operator equation is assumed to fit a given Hilbert scale, generated by some unbounded self-adjoint operator. Approximate reconstructions from random noisy data are obtained with general regularization schemes in such a way that these belong to the domain of the generator. The analysis has thus to distinguish two cases, the regular one, when the true solution also belongs to the domain of the generator, and the ‘oversmoothing’ one, when this is not the case. Rates of convergence for the regularized solutions will be expressed in terms of certain distance functions. For solutions with smoothness given in terms of source conditions with respect to the scale generating operator, then the error bounds can then be made explicit in terms of the sample size.

Here, we show that an ultracold atomic sample coupled to a nanomechanical resonator via oscillating magnetic fields can be used to cool the resonator's mechanical motion, to measure the mechanical temperature, and to enable entanglement of these mesoscopic objects. We calculate the expected coupling for both permanent-magnet and current-conducting nanostring resonators and describe how this hybridization is attainable using recently developed fabrication techniques, including SiN nanostrings and atom chips.

description: Purpose: This study examined the effect of open access (OA) status on scholarly and societal metrics of impact (citation counts and altmetric scores, respectively) across manuscripts published in the American Speech-Language-Hearing Association (ASHA) Journals.Method: Three thousand four hundred nineteen manuscripts published in four active ASHA Journals were grouped across three access statuses based on their availability to the public: Gold OA, Green OA, and Closed Access. Two linear mixed-effects models tested the effects of OA status on citation counts and altmetric scores of the manuscripts.Results: Both Green OA and Gold OA significantly predicted a 2.70 and 5.21 respective increase in citation counts compared with Closed Access manuscripts (p < .001). Gold OA was estimated to predict a 25.7-point significant increase in altmetric scores (p < .001), but Green OA was only marginally significant (p = .68) in predicting a 1.44 increase in altmetric scores relative to Closed Access manuscripts.Discussion: Communication sciences and disorders (CSD) research that is fully open receives more online attention and, overall, more scientific attention than research that is paywalled or available through Green OA methods. Additional research is needed to understand secondary variables affecting these and other scholarly and societal metrics of impact across studies in CSD. Ongoing support and incentives to reduce the inequities of OA publishing are critical for continued scientific advancement.Long, H. L., Drown, L., & El Amin, M. (2023).

description: The superfluid to Mott insulator transition and the superradiant transition are textbook examples for quantum phase transition and coherent quantum optics, respectively. Recent experiments in ETH and Hamburg succeeded in loading degenerate bosonic atomic gases in optical lattices inside a cavity, which enables the first experimental study of the interplay between these two transitions. In this letter we present the theoretical phase diagram for the ETH experimental setup, and determine the phase boundaries and the orders of the phase transitions between the normal superfluid phase, the superfluid with superradiant light, the normal Mott insulator and the Mott insulator with superradiant light. We find that in contrast to the second-order superradiant transition in a weakly interacting Bose condensate, strong correlations in the superfluid nearby a Mott transition can render the superradiant transition to a first order one. Our results will stimulate further experimental studies of interactions between cavity light and strongly interacting quantum matters.

description: The random walker method for image segmentation is a popular tool for semi-automatic image segmentation, especially in the biomedical field. However, its linear asymptotic run time and memory requirements make application to 3D datasets of increasing sizes impractical. We propose a hierarchical framework that, to the best of our knowledge, is the first attempt to overcome these restrictions for the random walker algorithm and achieves sublinear run time and constant memory complexity. The goal of this framework is -- rather than improving the segmentation quality compared to the baseline method -- to make interactive segmentation on out-of-core datasets possible. The method is evaluated quantitavely on synthetic data and the CT-ORG dataset where the expected improvements in algorithm run time while maintaining high segmentation quality are confirmed. The incremental (i.e., interaction update) run time is demonstrated to be in seconds on a standard PC even for volumes of hundreds of gigabytes in size. In a small case study the applicability to large real world from current biomedical research is demonstrated. An implementation of the presented method is publicly available in version 5.2 of the widely used volume rendering and processing software Voreen (https://www.uni-muenster.de/Voreen/).

description: We compare the physical and morphological properties of z ~ 2 Lyman-alpha emitting galaxies (LAEs) identified in the HETDEX Pilot Survey and narrow band studies with those of z ~ 2 optical emission line galaxies (oELGs) identified via HST WFC3 infrared grism spectroscopy. Both sets of galaxies extend over the same range in stellar mass (7.5 < logM < 10.5), size (0.5 < R < 3.0 kpc), and star-formation rate (~1 < SFR < 100). Remarkably, a comparison of the most commonly used physical and morphological parameters -- stellar mass, half-light radius, UV slope, star formation rate, ellipticity, nearest neighbor distance, star formation surface density, specific star formation rate, [O III] luminosity, and [O III] equivalent width -- reveals no statistically significant differences between the populations. This suggests that the processes and conditions which regulate the escape of Ly-alpha from a z ~ 2 star-forming galaxy do not depend on these quantities. In particular, the lack of dependence on the UV slope suggests that Ly-alpha emission is not being significantly modulated by diffuse dust in the interstellar medium. We develop a simple model of Ly-alpha emission that connects LAEs to all high-redshift star forming galaxies where the escape of Ly-alpha depends on the sightline through the galaxy. Using this model, we find that mean solid angle for Ly-alpha escape is 2.4+/-0.8 steradians; this value is consistent with those calculated from other studies.

description: Phosphorus dopant pastes present an interesting alternative to the conventional POCl3 dopant source for the emitter formation, because they allow the processing of selective emitters in an industrial fashion. In this paper, eleven different doping pastes from four manufacturers are investigated with regard to their gettering efficacy. The analysis of the effective minority carrier lifetimes of multicrystalline silicon wafers with gettering based on single-sided screen-printed emitters reveals that the gettering is slightly more effective than gettering with double-sided POCl3 emitters. Wafers which were gettered with single-sided screen-printed emitters achieve effective carrier lifetimes of up to 12.6 μs. In comparison, the reference double-sided POCl3 gettered wafer achieves an effective carrier lifetime of 8.5 μs. The emitter sheet resistances of investigated samples are in a typical range of conventional solar cell emitters of around 60 Ω/ and therefore are directly applicable for industrial manufacturing of solar cells. Also the apparent implied open circuit voltage of wafers with screen-printed emitter gettering is the highest. However these values are affected by trapping effects and therefore overestimated by contribution of traps to the excess carrier density.

description: Purpose: This study examined the effect of open access (OA) status on scholarly and societal metrics of impact (citation counts and altmetric scores, respectively) across manuscripts published in the American Speech-Language-Hearing Association (ASHA) Journals. Method: Three thousand four hundred nineteen manuscripts published in four active ASHA Journals were grouped across three access statuses based on their availability to the public: Gold OA, Green OA, and Closed Access. Two linear mixed-effects models tested the effects of OA status on citation counts and altmetric scores of the manuscripts. Results: Both Green OA and Gold OA significantly predicted a 2.70 and 5.21 respective increase in citation counts compared with Closed Access manuscripts (p < .001). Gold OA was estimated to predict a 25.7-point significant increase in altmetric scores (p < .001), but Green OA was only marginally significant (p = .68) in predicting a 1.44 increase in altmetric scores relative to Closed Access manuscripts. Discussion: Communication sciences and disorders (CSD) research that is fully open receives more online attention and, overall, more scientific attention than research that is paywalled or available through Green OA methods. Additional research is needed to understand secondary variables affecting these and other scholarly and societal metrics of impact across studies in CSD. Ongoing support and incentives to reduce the inequities of OA publishing are critical for continued scientific advancement. Long, H. L., Drown, L., & El Amin, M. (2023).

description: Ammonia is a potentially corrosive gas which evolves in livestock farming in the rural environment.
This is one major sector of the application of photovoltaic modules. The purpose of this work is to assess the effects
of ammonia gas on PV modules for rural applications by proposing a valid accelerated test. In order to do so, the
following approach is taken: (i) Dominant potential failure mechanisms in the reaction of ammonia with PV modules
are identified by applying high ammonia concentrations (50,000 ppm) to major components (encapsulation materials,
front glass ...) and evaluating the damage mechanisms. (ii) The permeation of ammonia through common encapsulant
and back skin polymer materials (EVA and Tedlar/ PET/ Tedlar) is evaluated quantitatively. (iii) The results are used
to design an accelerated test for PV modules to mimic the ammonia-induced load during application in the rural environment
in Middle Europe for a typical operating time. Various test designs are compared with a reference scenario
of ammonia-induced degradation of PV modules. Of all proposed test design, the DLG design is the only one compatible
with the reference scenario. For SCHOTT Solar modules Poly 3xx and Poly 2xx, (i) the values of Pmpp after
the DLG test are within ± 1% of the initial values, (ii) only minor changes in the visual appearance are noticed, (iii)
electrical isolation testing with and without wet treatment are passed and remain unchanged after the test.

description: In order to optimally design materials, it is crucial to understand the structure-property relations in the material by analyzing the effect of microstructure parameters on the macroscopic properties. In computational homogenization, the microstructure is thus explicitly modeled inside the macrostructure, leading to a coupled two-scale formulation. Unfortunately, the high computational costs of such multiscale simulations often render the solution of design, optimization, or inverse problems infeasible. To address this issue, we propose in this work a non-intrusive reduced basis method to construct inexpensive surrogates for parametrized microscale problems; the method is specifically well-suited for multiscale simulations since the coupled simulation is decoupled into two independent problems: (1) solving the microscopic problem for different (loading or material) parameters and learning a surrogate model from the data; and (2) solving the macroscopic problem with the learned material model. The proposed method has three key features. First, the microscopic stress field can be fully recovered. Second, the method is able to accurately predict the stress field for a wide range of material parameters; furthermore, the derivatives of the effective stress with respect to the material parameters are available and can be readily utilized in solving optimization problems. Finally, it is more data efficient, i.e. requiring less training data, as compared to directly performing a regression on the effective stress. For the microstructures in the two test problems considered, the mean approximation error of the effective stress is as low as 0.1% despite using a relatively small training dataset. Embedded into the macroscopic problem, the reduced order model leads to an online speed up of approximately three orders of magnitude while maintaining a high accuracy as compared to the FE$^2$ solver.

description: An optimistic industrial and commercial growth of CPV systems will be successfully possible with the
creation of standardization norms that regulate not only the design and manufacturing stages, but the energy and
power rating too, apart from other requirements discussed for traditional flat-PV.
The research group IDEA, from the University of Jaen, has made a preliminary CPV technology study, where
it was detected the lack of CPV standardization norms. The IEC 62108 norm, which is an evolution of the IEEE 1513
standard, is the first international standard developed exclusively for CPV technology, and it is a compendium of
accelerated aging tests that identify long-term reliability problems in the CPV modules or assemblies, reducing the
risk of failure, which means to guarantee the durability and reliability of the CPV systems
Nowadays certification companies are encountering some problems when applying the test sequence described in
the standard mentioned above and they also have detected some critical points in the norm, especially in the
excessive duration and the strict requirements of some of the test.
Modified Korteweg-de Vries solitons at supercritical densities in two-electron temperature plasmas

description: The supercritical composition of a plasma model with cold positive ions in the presence of a two-temperature electron population is investigated, initially by a reductive perturbation approach, under the combined requirements that there be neither quadratic nor cubic nonlinearities in the evolution equation. This leads to a unique choice for the set of compositional parameters and a modified Korteweg-de Vries equation (mKdV) with a quartic nonlinear term. The conclusions about its one-soliton solution and integrability will also be valid for more complicated plasma compositions. Only three polynomial conservation laws can be obtained. The mKdV equation with quartic nonlinearity is not completely integrable, thus precluding the existence of multi-soliton solutions. Next, the full Sagdeev pseudopotential method has been applied and this allows for a detailed comparison with the reductive perturbation results. This comparison shows that the mKdV solitons have slightly larger amplitudes and widths than those obtained from the more complete Sagdeev solution and that only slightly superacoustic mKdV solitons have acceptable amplitudes and widths, in the light of the full solutions.
