description: Abstract: Mesophotic marine ecosystems are characterized by lower light penetration supporting specialized fish fauna. Due to their depths (-30 to -150 m), accessibility is challenging, and the structure of mesophotic fish assemblages is generally less known than either shallow reefs or deep zones with soft bottoms which are generally trawled. Environmental DNA metabarcoding from seawater filtered in situ could improve our ability to monitor the diversity of mesophotic ecosystems. Here, we developed and tested a submersible standalone pumping device allowing targeted marine water filtering to explore the biodiversity of two mesophotic ecosystems, one temperate along the Provence coast in the North-Western Mediterranean Sea and one tropical at the seamount La Pérouse in the Western Indian Ocean. We filtered water samples from depths ranging between 0 and 200 m in the Mediterranean Sea and between 60 and 140 m in the Indian Ocean and applied a metabarcoding protocol using the teleo primer pair targeting the 12S mitochondrial rDNA (Actinopterygii and Chondrichthyes). For both study regions, our eDNA survey was able to recover highly diverse fish assemblages and the compositional analysis of eDNA samples showed both a marked signal of fish compositional turnover and overlapping taxa between depth zones. Further, we observed that a substantial number of species were found in samples collected in depths beyond their reported depth range suggesting an underestimation of species’ depth tolerances. eDNA metabarcoding should thus complement existing knowledge of species' geographic distributions across space and depth. Overall, our results demonstrate the potential of eDNA metabarcoding for future mesophotic surveys as it allows fast and broad biodiversity assessment.
 R-Scripts: These R-Scripts were used to clean and analyse the eDNA data from La Pérouse and the Provence coasts (OBItool and SWARM pipeline) as well as their synthesis data sets. The results were used for the Environmental DNA article "Environmental DNA highlights fish biodiversity in mesophotic ecosystems".

description: Front surface nanotexturing of silicon is investigated using a capacitively coupled reactive ion etching SF6/O2 discharge at room temperature. The plasma is either powered with a standard RF voltage at 13.56 MHz, or an innovative multi-frequency approach named Tailored Voltage Waveforms (TVWs). It has been shown that by using TVWs, it is possible to significantly modify the ion bombardment energy (IBE) at the substrate while keeping the discharge power constant. Measurements suggest that increasing IBE is beneficial in achieving low reflectance values in a short process time, although the role of other mechanisms at play has still to be clarified. Nanotextured samples have then been coated by thermal ALD with a 7 nm thick Al2O3 passivation layer. The simultaneous effects of surface area enhancement and plasma induced damage of the passivation quality are successfully dissociated, and it is shown that increasing the IBE (in the range from 80 to 200 eV) strongly increases the surface recombination velocity (SRV). However, one can achieve both low reflectance (less than 5%) and good passivation quality (front SRV around 40 cm/s), without the need for an additional chemical damage removal etching. Furthermore, the possibility of recovering the passivation through a “dry” damage removal etching is examined.

description: this work, we demonstrate a promising and cost competitive technology for “black” silicon
formation on c-Si wafers. For this we proposed a method for wafer size surface texturing of silicon substrate based on
a large area surface coating by a nanometer-thin nickel film and subsequent thin nickel film assisted chemical etching
(TNFACE). We investigated a relationship between the technological conditions, the surface morphology and optical
reflection. We demonstrate that a large area of crystalline Si wafer can be covered homogeneously by the “black”
silicon with average reflectivity less than about 2% in the visible light range after etching for 5 min.

description: Multilingual pre-trained models are able to zero-shot transfer knowledge from rich-resource to low-resource languages in machine reading comprehension (MRC). However, inherent linguistic discrepancies in different languages could make answer spans predicted by zero-shot transfer violate syntactic constraints of the target language. In this paper, we propose a novel multilingual MRC framework equipped with a Siamese Semantic Disentanglement Model (SSDM) to disassociate semantics from syntax in representations learned by multilingual pre-trained models. To explicitly transfer only semantic knowledge to the target language, we propose two groups of losses tailored for semantic and syntactic encoding and disentanglement. Experimental results on three multilingual MRC datasets (i.e., XQuAD, MLQA, and TyDi QA) demonstrate the effectiveness of our proposed approach over models based on mBERT and XLM-100. Code is available at:https://github.com/wulinjuan/SSDM_MRC.

Heterojunction Solar Cells

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 780-782
description: Hetero-junction back-contact (HBC) solar cell is the structure realizing the highest efficiency ever
obtained. For lowering the cost of crystalline-silicon (c-Si) solar cells, thinning of the original c-Si substrates is also
required to reduce the material cost. In such c-Si substrates thinner than 100 μm, the optical reflection of sunlight at
the back surface becomes an important key technology, and thus, texturing of the back surface is to be also important.
However, in HBC solar cells, the electrode patterning must be performed on such textured back-surface. Then, small
size textures should be developed for realizing both high reflectivity at the back-surface and efficient pattern-formation
of the back-electrodes. Small size textures are also required for thin c-Si, since several μm size textures fluctuate the c-
Si thickness itself and induce unstable performance. In the paper, it is demonstrated that the size of texture can be
controlled from 10 μm or more to sub-micron by adding glass microparticles in the conventional alkaline-based textureforming
chemicals, and that such textured structures exhibited the reflectivity lower than 10% in the range of
wavelength from 600 nm to 950 nm even for the 50 μm-thick c-Si substrates, before anti-reflection coating.

description: Although mobile social networking sites have successfully penetrated into individual’s various aspects of everyday lives, few empirical studies have investigated important antecedents of civic involvement in the WeChat context from a network capital perspective. The principal aims of the research are to systematically explore the underlying associations between mobile social media use, network heterogeneity, network capital, and civic participation among young people. The data was collected in an online survey of 1,208 young people in mainland China. Structural equation modeling analysis was carried out to examine the corresponding hypotheses. Findings revealed that informational WeChat use could positively impact young people’s network heterogeneity, which subsequently contributes to increased degrees of civic involvement. Additionally, the results demonstrated that network heterogeneity and network capital on WeChat are positively associated with civic involvement. Furthermore, network heterogeneity and network capital could mediate the association between WeChat use for information and individual’s civic activities. These obtained outcomes underlined the vital role of mobile social media communication in facilitating democratic engagement of young citizens in contemporary mobile media-saturated society.

description: We discuss a detailed analysis of the potential efficiency improvements of state-of-the-art industrial p-type multicrystalline silicon solar cells with passivated emitter and rear with an average energy conversion efficiency of 19.0%. The aim is to identify the limitations of cells currently fabricated in industry, not of record laboratory cells, and to demonstrate approaches for research institutes and industry to further optimise the devices using industrially applicable processes. According to the analysis, front surface reflection of the active cell area bears the largest potential for increasing the efficiency by replacing the standard acidic texture by a honeycomb texture, which is estimated to improve the efficiency from 19% to 20%. Reducing shading and recombination at the front metal is the second largest potential efficiency increase. We expect that reducing the metal finger width from 50 μm to 40 μm or below is feasible and increases the efficiency further to 20.2%.

description: The possibility of using hyperspectral imaging of photoluminescence to detect oxygen in n-type Cz-Si wafer was investigated. Wafers from the seed and tail end of an ingot were studied. The method OxyMap was used on twin wafers for quantification of the oxygen content. PL signals previously associated with radiative recombination of charge carriers through traps introduced by interstitial oxygen, Oi, were detected in the same area as was associated with a high oxygen content (seed end). The P-line and what may be phonon replicas were seen as pronounced signals in the seed end in cooled samples (90 K). For room temperature a broad defect related luminescence signal with center peak at 0,72 eV was recorded in addition to luminescence from the band to band transition at 1,1 eV.

description: Supernova neutrinos have several exceptional features which can lead to interesting physical consequences. At the production point their wave packets have an extremely small size $σ_x \sim 10^{-11}$ cm; hence the energy uncertainty can be as large as the energy itself, $σ_E \sim E$, and the coherence length is short. On the way to the Earth the wave packets of mass eigenstates spread to macroscopic sizes and separate. Inside the Earth the mass eigenstates split into eigenstates in matter and oscillate again. The coherence length in the Earth is comparable with the radius of the Earth. We explore these features and their consequences. (i) We present new estimates of the wave packet size. (ii) We consider the decoherence condition for the case of wave packets with spatial spread and show that it is not modified by the spread. (iii) We study the coherence of neutrinos propagating in a multi-layer medium with density jumps at the borders of layers. In this case coherence can be partially restored due to a "catch-up effect", increasing the coherence length beyond the usual estimate. This catch-up effect can occur for supernova neutrinos as they cross the shock wave fronts in the exploding star or the core of the Earth.

description: Stockholm University (SU) has developed a software script package for harvest and transformation of metadata and data files from data repositories such as Figshare or Zenodo that are used by SU researchers. The metadata is collected from these repositories, partly enriched with metadata from other sources and then transformed to Swedish National Archives Common Specification Package standard (FGS METS), to be stored together with the associated data files that are fetched simultaneously as SIPs (Submission Information Packages) in the SU local (temporal) archive, awaiting future transformation to AIPs (Archival Information Packages). The end product of this harvest and transformation processing are SIPs where the transformed metadata sip.xml files validate against the FGS - Common Specification Package schemas, (http://xml.ra.se/e-arkiv/METS/CSPackageMETS.xsd and http://xml.ra.se/e-arkiv/METS/CSPackageExtensionMETS.xsd). The associated data files are not transformed or converted in this first step towards long-term preservation and archiving, but we keep track of the file formats ingested partly by mapping file extensions to mimetypes in an XSLT script.
 The software scripts that were developed for this harvester and transformer are in BASH Unix Shell, XQuery and XSLT. The processing of metadata, data and scripts occurs locally using Git Bash (for Windows), BaseX and Oxygen XML editor, but is essentially software-tool agnostic. Metadata input sources are e.g. OAI-PMH METS feeds from su.figshare.com, API - https://api.figshare.com/v2/articles/, orcid.org and a local list of departments at SU.

description: We introduce a new thermal evaporation system featuring good contact formation without a post
deposition annealing process developed by SINGULUS. Compared to an in-line high-rate thermal evaporation system,
the new metallization technology showed no losses in efficiency on n-PERT rear junction solar cells. In this work, we
analyze the electrical properties of the processed solar cell devices to understand effects induced by the new metallization
technique. It is shown that the pre-heating unit for substrates of the new evaporation system helps to avoid a post
deposition annealing step. The saved process time can increase throughput and helps to reduce production costs.
Therefore this technique eliminates another factor separating evaporated metallization from transfer to industrial mass
production so far.

description: We have developed 22%-efficient n-Type Rear Junction PERT (Passivated Emitter Rear Totallydiffused)
Cells that have the wafer thickness around 100μm since 2014. In the course of this development, we
optimized gas composition for boron emitter by Atmospheric Pressure Chemical Vapor Deposition (APCVD) in 2015
and laser opening process conditions, such as power and pulse duration were optimized in 2016. Finally, we have
achieved 22% efficiency by optimizing the surface concentrations of boron and phosphorus doped layers. IV
parameters of the champion cell are Voc of 685.3mV, Isc of 9.49A, FF of 80.95% and Efficiency of 22.03%.
(Calibrated by SERIS, Singapore) The final wafer thickness of the champion cell is 106μm. Efficiency have been
improved mainly by Voc increment, which is about 15mV compared to the previous cell IV results obtained at 2015.
This result has been obtained mainly due to the reduction of surface recombination by minimized surface doping
concentrations.

description: APCVD (atmospheric pressure chemical vapor deposition) offers promising improvements for the
PERT (passivated emitter rear totally diffused) solar cell concept. One-sided diffusion of P as well as B allows
reduced processing steps. In this work the gettering efficacy of P- and B-doped layers deposited by APCVD on mc
(multicrystalline) Si (silicon) material is evaluated by minority charge carrier lifetime measurements.
Comparison with the influence of thermal load showed that P-gettering resulted in significant lifetime increase,
whereas temperature treatment without PSG (phosphor silicate glass) induced the opposed effect. Close to the
crucible wall, the local defect structure in the wafer leads in ungettered samples to negative effects that can be
strongly reduced by P-gettering. In addition, the APCVD PSG layers showed at least comparable gettering efficacy to
standard POCl3-gettering via diffusion in a quartz tube furnace. Finally, co-diffusion of APCVD PSG and BSG layers
was tested for a PERT concept.

description: Imagine an oracle that correctly predicts the outcome of every particle physics experiment, the products of every chemical reaction, or the function of every protein. Such an oracle would revolutionize science and technology as we know them. However, as scientists, we would not be satisfied with the oracle itself. We want more. We want to comprehend how the oracle conceived these predictions. This feat, denoted as scientific understanding, has frequently been recognized as the essential aim of science. Now, the ever-growing power of computers and artificial intelligence poses one ultimate question: How can advanced artificial systems contribute to scientific understanding or achieve it autonomously? We are convinced that this is not a mere technical question but lies at the core of science. Therefore, here we set out to answer where we are and where we can go from here. We first seek advice from the philosophy of science to understand scientific understanding. Then we review the current state of the art, both from literature and by collecting dozens of anecdotes from scientists about how they acquired new conceptual understanding with the help of computers. Those combined insights help us to define three dimensions of android-assisted scientific understanding: The android as a I) computational microscope, II) resource of inspiration and the ultimate, not yet existent III) agent of understanding. For each dimension, we explain new avenues to push beyond the status quo and unleash the full power of artificial intelligence's contribution to the central aim of science. We hope our perspective inspires and focuses research towards androids that get new scientific understanding and ultimately bring us closer to true artificial scientists.

description: The permanent demand on the improvement of solar cell efficiency and reduction of production costs
has placed much focus on the multiple Cz-pulling techniques from a single crucible. PVA Crystal Growing Systems
GmbH has developed a mobile recharge system for Czochralski pullers, the SiCharger MRS. This system and its
potential was presented in detail at the 33rd EU PVSEC [1]. Another way to save costs while increasing productivity
is a higher pull rate. In order to enable a higher pull speed at a stable crystal growth, the hot zone was investigated
and optimized. The entire crystal growth arrangement was simulated with the commercial program package CGSim
[2]. As a result, the pull rate could be significantly increased resulting in an appreciable saving of energy and process
gas. In the next approach, an active crystal cooling system was implemented. This device consists of a water cooled
container, which is placed a few centimeters above the phase boundary of the growing crystal, in order to increase the
temperature gradient in the growing crystal close to its solidification interface. With this arrangement the heat
transport through the crystal is improved. Crystals with 8 inch diameter were grown with a pull rate of 1.7 mm/min.

description: We analyze the dynamical response functions of strongly interacting quantum critical states described by conformal field theories (CFTs). We construct a self-consistent holographic model that incorporates the relevant scalar operator driving the quantum critical phase transition. Focusing on the finite temperature dynamical conductivity $σ(ω,T)$, we study its dependence on our model parameters, notably the scaling dimension of the relevant operator. It is found that the conductivity is well-approximated by a simple ansatz proposed by Katz et al [1] for a wide range of parameters. We further dissect the conductivity at large frequencies $ω>> T$ using the operator product expansion, and show how it reveals the spectrum of our model CFT. Our results provide a physically-constrained framework to study the analytic continuation of quantum Monte Carlo data, as we illustrate using the O(2) Wilson-Fisher CFT. Finally, we comment on the variation of the conductivity as we tune away from the quantum critical point, setting the stage for a comprehensive analysis of the phase diagram near the transition.

Visual searching (e.g., image, sketch) is structured and easy to adopt. Current visual search approaches count on a complete screen and are therefore slow and tedious. PSDoodle employs a deep neural network to recognize partial screen element drawings instantly on a digital drawing interface and shows results in real-time. PSDoodle is the first tool that utilizes partial sketches and searches for screens in an interactive iterative way. PSDoodle supports different drawing styles and retrieves search results that are relevant to the user's sketch query. A short video demonstration is available online at: https://youtu.be/3cVLHFm5pY4

description: This paper aims at investigating the polysemic patterns associated with the notion ‘soil/earth’ by using the semantic map model as a methodological tool. We focus on the applicability of the model to the lexicon, since most of past research has been devoted to the analysis of grammatical morphemes. The most concise result of our research is a diagrammatic visualization of the semantic spaces of twenty lexemes in nine different languages, mainly ancient languages belonging to the Indo-European and the Afro-Asiatic language families. The common semantic map for the various languages reveals that the semantic spaces covered by the investigated lexemes are often quite different from one another, although common patterns can also be detected. Our study highlights some shortcomings and methodological problems of previous analyses suggesting that a possible solution to these problems is the control of the data in the existing sources of the object languages. Finally, drawing upon the cognitive linguistics literature on the various types of semantic change, we show that some of the senses of the individual lexemes are the result of the function of such mechanisms as metaphor, metonymy, and generalization.

description: The aim of the present work is to demonstrate processing of polycrystalline free-standing Si wafers and
thin Si layers on various substrates using thermal spray of relevant Si powders, including recycled ones. Silicon powders
were fabricated by milling from two different Si feedstocks: (i) Si kerf produced during sawing of Si wafers from the
ingots, and (ii) Si powder from Si scrap (broken wafers). Two different Si powder based structures were produced by
thermal spray: (i) free-standing Si-based wafers with thicknesses of about 300-400 micrometres and sizes up to 6 inches,
which can be used as supporting parts for "Si wafer equivalent" structures, and, (ii) Si-based layers with thicknesses of
about 50-100 micrometres deposited on different supporting substrates, such as aluminium, glass and highly conductive
Si powder based sintered substrates. Raman spectroscopy, resistivity, and SEM analyses have been used for
characterization of the Si based structures fabricated by thermal spray. It is observed that such layers are poly-crystalline
with a low-fraction of the amorphous phase and can be considered as a low-cost alternative for Si PV, which are based on
utilization of Si wafers and thin Si layers deposited by conventional methods such as CVD, PECVD, e-beam, etc.

description: Meine Doktorarbeit behandelt hauptsächlich den todfeindlichen Kampf zwischen Nietzsches Philosophie und Jesus Lehre, im Nietzsches Worte, Judda gegen Rom, Rom gegen Judda. Ich habe versucht, die Quelle dieses Kampfes begrifflich zu erklären. Dafür habe ich den Begriff 'Inkompatibilität' verwendet und ich habe auch versucht, den scheinbaren Widerspruch der Begriffe von Nietzsche zu erklären, z. B., die Kritik an Willensfreiheit und die Freiheit des freien Geistes, der scheinbare Widerspruch zwischen Wille zur Macht und ewiger Wiederkehr des Gleichen und die begriffliche Beziehung zwischen Philosophie und Wissenschaft. Man kann nur einen Standpunkt von Judda gegen Rom haben, weil dieser Kampf keinen Kompromiß erlaubt.
description: My PhD thesis treat mainly deadly battle between Nietzschean philosophy and christian doctrine, in Nietzschean concept, Jew against Rome, Rome against Jew. The source of this battle has been conceptually explained. The incompatibility describes the source of that deadly battle. The seeming inconsistency of Nietzschean concepts has been explained on entire context of Nietzschean philosophy, for example, the critique of the freedom of will and the freedom of free spirit, the seeming contradiction between will to power and eternal recurrence and conceptual relationship between philosophy and science. Just one standpoint can be chosen between Jew against Rome, because this battle doesn't allow any compromise between them.
Odd-parity superconductors with two-component order parameters: nematic and chiral, full gap and Majorana node

description: Motivated by the recent experiment indicating that superconductivity in the doped topological insulator Cu$_x$Bi$_2$Se$_3$ has an odd-parity pairing symmetry with rotational symmetry breaking, we study the general class of odd-parity superconductors with two-component order parameters in trigonal and hexagonal crystal systems. In the presence of strong spin-orbit interaction, we find two possible superconducting phases below $T_c$, a time-reversal-breaking (i.e., chiral) phase and an anisotropic (i.e., nematic) phase, and determine their relative energetics from the gap function in momentum space. The nematic superconductor generally has a full quasi-particle gap, whereas the chiral superconductor with a three-dimensional (3D) Fermi surface has point nodes with lifted spin degeneracy, resulting in itinerant Majorana fermions in the bulk and topological Majorana arcs on the surface.

Characterisation & Simulation Methods

description: 33rd European Photovoltaic Solar Energy Conference and Exhibition; 857-860
description: Black silicon (b-Si) reduces drastically light reflectance in the front side of c-Si solar cells to values near
zero for the whole absorbed solar spectrum. In this work, we apply 2D and 3D simulations to explore the efficiency limits
of interdigitated back-contacted c-Si(n) solar cells with line or point contacts respectively, using ALD Al2O3 passivated
b-Si in the front surface. Realistic physical and technological parameters involved in a conventional oven-based
fabrication process are considered in the simulations, especially those related to surface recombination on the b-Si as well
as high doped p+/n+ strip regions. One important issue is the temporal stability of surface passivation on b-Si surfaces. In
this work experimental long-term b-Si surface passivation data after two years and its impact on cell performance are
studied. Simulations demonstrate initial and final photovoltaic efficiencies over 24.6% and 23.2% respectively for an
emitter coverage of 80% independently of the cell contact strategy. A photocurrent loss about 1.3 mA/cm2 occurs when
surface recombination velocity at the b-Si surfaces degrades from 6 cm/s to a final value of 28 cm/s.

description: Accurate simulations of combustion phenomena require the use of detailed chemical kinetics in order to capture limit phenomena such as ignition and extinction as well as predict pollutant formation. However, the chemical kinetic models for hydrocarbon fuels of practical interest typically have large numbers of species and reactions and exhibit high levels of mathematical stiffness in the governing differential equations, particularly for larger fuel molecules. In order to integrate the stiff equations governing chemical kinetics, generally reactive-flow simulations rely on implicit algorithms that require frequent Jacobian matrix evaluations. Some in situ and a posteriori computational diagnostics methods also require accurate Jacobian matrices, including computational singular perturbation and chemical explosive mode analysis. Typically, finite differences numerically approximate these, but for larger chemical kinetic models this poses significant computational demands since the number of chemical source term evaluations scales with the square of species count. Furthermore, existing analytical Jacobian tools do not optimize evaluations or support emerging SIMD processors such as GPUs. Here we introduce pyJac, a Python-based open-source program that generates analytical Jacobian matrices for use in chemical kinetics modeling and analysis. As a demonstration, we first establish the correctness of the Jacobian matrices for kinetic models of hydrogen, methane, ethylene, and isopentanol oxidation, then demonstrate the performance achievable on CPUs and GPUs using pyJac via matrix evaluation timing comparisons.

description: This paper presents a methodology that forms an automated tool for robot kinematic representation conversion, called the RobKin Interpreter. It is a set of analytical algorithms that apply basic linear algebra tools that can analyze an input serial robot representation, express the joints globally in matrix form, and map to other representations such as standard Denavit-Hartenberg parameters, Roll-Pitch-Yaw angles with translational displacement, and Product of Exponentials with a possibility to generate a URDF (Universal Robot Description Format) file from any of them. It works for revolute and prismatic joints and can interpret even arbitrary kinematic structures that do not have orthogonally placed joints and often appear in flexible robotic systems. The aim of the proposed methods is to facilitate the necessary switches between representations due to software compatibility, calculation simplification, or cooperation.

description: The cost reduction of the solar cells devices becomes fundamental in the current situation of the
photovoltaic industry. A new device based on very thin upgraded metallurgical silicon (UMG-Si) is being analyzed.
The success of these cells requires a good behavior of the silicon substrates from a mechanical point of view. It’s well
known that the UMG-Si presents higher number of impurities compared with solar grade silicon. Once the cracks
originated by the wafering process are removed by chemical baths, these impurities are the origin of the wafer failure.
This paper analyzes the strength of these substrates in comparison with the solar grade silicon substrates in order to
establish if it’s necessary to handle or not with special care these new substrates.
