description: Pleistocene dispersal dynamics played a major role in shaping the spatial patterns of biodiversity distribution. Still, growing evidence has unveiling the contribute of phenotypic trait variation in affecting dispersal dynamics and, in turn, the pattern of intraspecific genetic diversity. With this study, we contribute to the understanding of the genomic underpinnings of phenotypic integration in behavioral and physiological traits linked to the dispersal processes. To meet this aim, we generated the first brain de-novo transcriptome of a species showing marked behavioral and physiological differentiation across populations spanning its last Pleistocene re-colonization route, the Tyrrenhian tree frog Hyla sarda. In particular, we sequences the brain transcriptome of individuals from either source (Sardinia) and colonized (Corsica) areas, and showing phenotypic differentiation at multiple traits. Furthermore, we present a custom pipeline with novel transcriptome-specific algorithms for RNA-seq data analysis, a de-novo transcriptome assembly, its validation, and subsequent annotation.

description: We find a natural compatible condition between the Rota-Baxter operator and Turaev's (Hopf) group-(co)algebras, which leads to the concept of Rota-Baxter Turaev's (Hopf) group-(co)algebra. Two characterizations of Rota-Baxter Turaev's group-algebras (abbr. T-algebras) are obtained: one by Atkinson factorization and the other by T-quasi-idempotent elements. The relations among some related Turaev's group algebraic structures (such as (tri)dendriform T-algebras, Zinbiel T-algebras, pre-Lie T-algebras, Lie T-algebras) are discussed, and some concrete examples from the algebras of dimensions 2,3 and 4 are given. At last we prove that Rota-Baxter Poisson T-algebras can produce pre-Poisson T-algebras and Poisson T-algebras can be obtained from pre-Poisson T-algebras.

description: The requirements for the industrial application of crucible coatings for the directional solidification process
of multi crystalline (mc) silicon ingots aim to a higher stability against the harsh atmospheric conditions used during the
ingot processing cycle. The aim of this work was to investigate the silicon-substrate interaction of two different crucible
materials coated with the same Si3N4-based coating under different gas flow and furnace pressure conditions. Therefore, a
special sessile drop furnace was developed. In this study an industrially used porous crucible material and a dense SiO2-
glass were compared as substrate material with regard to the macroscopic contact angle and the infiltration behavior
beneath and beside of a silicon droplet. The results show that completely different stability areas exist for the two
investigated crucible-coating systems. It turns out that the pore free SiO2-glass substrate shows an increased stability area
for gas flow and furnace pressure, maybe due to the absence of a gaseous SiO(g) transport through the substrate
compared to the industrial-substrate which exhibits a higher porosity.

description: A scenario of an emergent universe is constructed in the background of an inhomogeneous space-time model which is asymptotically (at spatial infinity) FRW space-time. The cosmic substratum consists of non-interacting two components, namely {\bf a)} homogeneous and isotropic fluid but dissipative in nature and {\bf b)} an inhomogeneous and anisotropic barotropic fluid. In non-equilibrium thermodynamic prescription (second order deviations), particle creation mechanism is considered the cause for the dissipative phenomena. It is found that for constant value of the particle creation rate parameter there exists a scenario of emergent universe.

description: N-type silicon as a base material for solar cells is receiving an increasing amount of attention. One of
the defects occurring in n-type silicon are ring shaped patterns in lifetime maps (a.k.a. striation rings), which may
cause a significant decrease in conversion efficiency. These striation ring patterns are related to recombination active
oxygen clusters. Here, it is shown that the recombination activity of these clusters can be decreased by either light
exposure, low temperature annealing of samples with a SiNx coating or in-diffusion of hydrogen by performing a
forming gas annea (FGA), all of which can be applied on completed cells. A decrease in recombination activity is
observed at process temperatures up to 375 °C. However, exposure to process temperatures above 500 °C reverses
the mitigating effect of the treatments. Investigations to the UV stability of these treatments show no increase in
recombination activity so far. A side effect of the hydrogenation treatment by FGA is a change in resistivity, even
though the temperatures are kept below the thermal donor formation temperature.

description: The proliferation of contextualized knowledge in the Semantic Web (SW) has led to the popularity of knowledge formats such as \emph{quads} in the SW community. A quad is an extension of an RDF triple with contextual information of the triple. In this paper, we study the problem of query answering over quads augmented with forall-existential bridge rules that enable interoperability of reasoning between triples in various contexts. We call a set of quads together with such expressive bridge rules, a quad-system. Query answering over quad-systems is undecidable, in general. We derive decidable classes of quad-systems, for which query answering can be done using forward chaining. Sound, complete and terminating procedures, which are adaptations of the well known chase algorithm, are provided for these classes for deciding query entailment. Safe, msafe, and csafe class of quad-systems restrict the structure of blank nodes generated during the chase computation process to be directed acyclic graphs (DAGs) of bounded depth. RR and restricted RR classes do not allow the generation of blank nodes during the chase computation process. Both data and combined complexity of query entailment has been established for the classes derived. We further show that quad-systems are equivalent to forall-existential rules whose predicates are restricted to ternary arity, modulo polynomial time translations. We subsequently show that the technique of safety, strictly subsumes in expressivity, some of the well known and expressive techniques, such as joint acyclicity and model faithful acyclicity, used for decidability guarantees in the realm of forall-existential rules.

description: A new line scanning approach to photoluminescence imaging of silicon bricks has been applied to
overcome previous systematic limitations of conventional area scanning camera based systems. We demonstrate that
this approach yields significantly improved image quality and can expose the most relevant electronic properties of a
state of the art ‘high performance’ multicrystalline silicon brick. Building on previous work in using spectral
photoluminescence intensity ratios, a full suite of parameters including bulk lifetime, interstitial iron concentration,
gettered background lifetime, and predicted cell efficiency are imaged. Also, the application of automated image
defect recognition algorithms is enabled by the excellent image quality and demonstrated in principle.

description: We propose a new adaptive Particle-in-Cloud (AP-Cloud) method for obtaining optimal numerical solutions to the Vlasov-Poisson equation. Unlike the traditional particle-in-cell (PIC) method, which is commonly used for solving this problem, the AP-Cloud adaptively selects computational nodes or particles to deliver higher accuracy and efficiency when the particle distribution is highly non-uniform. Unlike other adaptive techniques for PIC, our method balances the errors in PDE discretization and Monte Carlo integration, and discretizes the differential operators using a generalized finite difference (GFD) method based on a weighted least square formulation. As a result, AP-Cloud is independent of the geometric shapes of computational domains and is free of artificial parameters. Efficient and robust implementation is achieved through an octree data structure with 2:1 balance. We analyze the accuracy and convergence order of AP-Cloud theoretically, and verify the method using an electrostatic problem of a particle beam with halo. Simulation results show that the AP-Cloud method is substantially more accurate and faster than the traditional PIC, and it is free of artificial forces that are typical for some adaptive PIC techniques.

description: Multicrystalline wafers are produced by directional solidification of molten silicon in a fused silica
crucible previously coated with a releasing agent mainly composed of silicon nitride. The interaction between the
crucible/coating and silicon results in the electrical properties degradation of a significant ingot edge layer, called red
zone, which cannot be processed into wafers. The red zone length has a direct impact on wafer production yield and
must be minimized.
This study explores solar cells results and wafer yield obtained with newly introduced Advanced SOLAR®
Crucible (ASC). Standard and ASC crucibles were coated with the same silicon nitride coating and used to grow 60 kg
silicon ingots. Red zone area, minority carrier lifetime mapping, impurities contaminations and solar cells results of
both ingots were compared.
Results demonstrate that ingot originated from the ASC crucible shows 20% smaller red zone than the standard
one. Minority carrier lifetime is significantly improved and lead to better cell efficiency, particularly in the red zone
but also in the bulk ingot where an increase of 0.3% absolute cell efficiency is achieved. Lifetime results and red zone
reduction look to be well correlated with dissolved iron concentration, demonstrating that the ASC crucible contributes
to lower iron diffusion.

description: Improving the efficiency of solar modules is still the most important task of photovoltaic and the
employment of potentially more effective material, silicon grown by the FZ (float zone) method, should contribute to
its solution. Previously, results in growing silicon rods for the FZ process have been described, including rod testing.
Issues with obtaining dislocation free single crystals from that rods arose. Problems were solved with new carbon free
hot zone, samples were cut from the bottom of the rod grown in the new thermal zone since alien particles and
contamination content at that part of the rod is considered potentially highest, single crystals were obtained without
dislocations. New hot zone also enabled new technique of pulling, yielding in ingots with resistivity of not less than
450 Ohm×cm, indicating low background impurity levels of the process. Rods under PID regulation are grown with
acceptable (+/-4 mm) fluctuation of diameter.

description: The ensemble Kalman inversion (EKI) for the solution of Bayesian inverse problems of type $y = A u +\varepsilon$, with $u$ being an unknown parameter, $y$ a given datum, and $\varepsilon$ measurement noise, is a powerful tool usually derived from a sequential Monte Carlo point of view. It describes the dynamics of an ensemble of particles $\{u^j(t)\}_{j=1}^J$, whose initial empirical measure is sampled from the prior, evolving over an artificial time $t$ towards an approximate solution of the inverse problem, with $t=1$ emulating the posterior, and $t\to\infty$ corresponding to the under-regularized minimum-norm solution of the inverse problem. Using spectral techniques, we provide a complete description of the deterministic dynamics of EKI and its asymptotic behavior in parameter space. In particular, we analyze the dynamics of naive EKI and mean-field EKI with a special focus on their time asymptotic behavior. Furthermore, we show that -- even in the deterministic case -- residuals in parameter space do not decrease monotonously in the Euclidean norm and suggest a problem-adapted norm, where monotonicity can be proved. Finally, we derive a system of ordinary differential equations governing the spectrum and eigenvectors of the covariance matrix. While the analysis is aimed at the EKI, we believe that it can be applied to understand more general particle-based dynamical systems.

Induktiv angeregte quecksilberfreie Hochdruckplasmen für den Einsatz in UV-Desinfektionssystemen

description: Nicht nur aufgrund der Ausbreitung der SARS-CoV-2-Pandemie im Jahr 2020, sondern auch aufgrund eines stetig wachsenden Bewusstseins der Bevölkerung für die Verbreitung von Infektionskrankheiten durch kontaminierte Luft und kontaminiertes Wasser rücken Desinfektionsanlagen immer mehr in den Fokus der Öffentlichkeit. Hierbei bieten UV-Desinfektionssysteme besondere Vorteile, wie z.B. relativ niedrige Betriebs- und Wartungskosten. Der Nachteil der zur Zeit genutzten Anlagen stellen die verwendeten Quecksilber-Niederdruckstrahler dar. Bereits Ende des 19. Jahrhunderts wurden die ersten UV-Strahlungsquellen auf Quecksilberbasis vorgestellt. Auch wenn die Effizienz dieser Strahler durch permanente Forschung verbessert werden konnte, war es bisher nicht realisierbar, das giftige und umweltschädliche Quecksilber in der UV-Erzeugung durch unbedenkliche Materialien zu ersetzen. An diesem Punkt setzt die vorliegende Arbeit an. Mitte der 2000er Jahre konnten durch die Entwicklung von Leistungstransistoren aus Siliciumcarbid (SiC) effiziente Vorschaltgeräte für Leistungen > 1 kW bei Frequenzen im MHz-Bereich realisiert werden. Somit ergibt sich ein neuer Ansatz, um induktiv angeregte Strahlungsquellen zu betreiben. Durch den elektrodenlosen Betrieb können jegliche Elektrodenreaktionen vernachlässigt werden. Dies eröffnet eine große Auswahl an möglichen Füllkomponenten. Die Erforschung der induktiv angeregten quecksilberfreien Hochdruckplasmen erfolgte in Bezug auf die spätere Anwendung, dem Einsatz in UV-Desinfektionssystemen. Das Verfahren zur Auswahl von Füllkomponenten der UV-Strahler stellt hierbei einen wichtigen Punkt dar und wird genau betrachtet. Des Weiteren wird auf die Messmethoden und die genutzte Leistungsversorgung eingegangen. Da es sich bei den untersuchten Strahlungsquellen um geschlossene Systeme handelt, wurde ein Simulationsmodell entwickelt, um interne Prozesse unter Einbezug des Startgases sowie bei der Nutzung von Halogenidkomponenten darzustellen. Die aus der Auswahl resultierenden Füllkomponenten wurden in Laborsystemen umgesetzt und die Spektren als auch die Effizienz der Plasmen bestimmt. Um eine verlässliche Zündung der Plasmen sowie einen effizienten Betrieb zu ermöglichen, folgte eine Geometrie- und Parameteruntersuchung. Auch die Zündhysterese und die Temperaturverteilung wurden in diese Untersuchungen mit einbezogen. Aus den vorgestellten Ergebnissen resultiert eine Prototyp-Konfiguration, welche erstmals eine Alternative zur derzeitigen Quecksilber-Technologie bieten könnte.

description: Exhaust Argon gas in vacuum lines of Czochralski pullers is inevitably contaminated by dust. The
particles consist of silicon in different states of oxidation (SiOx, x = 0…2). The dust is highly reactive and pyrogenic.
Its extremely small particle size makes it hazardous to health, environment and equipment. It is eventually oxidized to
silicon dioxide in an exothermic reaction. The dust needs to be removed from the exhaust gas before it enters the
vacuum pumps and is finally handled by an exhaust treatment system. Automated blowback filtration by sintered,
long-life stainless-steel elements is capable in completely removing the dust from the exhaust gas. In contrast to
conventional filtration by means of polymeric fiber media, the technology effectively protects operators, vacuum
pumps and environment. Crystal loss due to pump breakdown as well as manpower needs for filter exchange, dust
discharge, maintenance and repair are drastically reduced. The technology essentially lowers Total Cost of
Ownership and enables Return on Investment – depending on the features of the particular case – typically within less
than one year.

description: We report the distance and [Fe/H] value for the globular cluster NGC 5904 (M5) derived from the Fourier decomposition of the light curves of selected RRab and RRc stars. The aim in doing this was to bring these parameters into the homogeneous scales established by our previous work on numerous other globular clusters, allowing a direct comparison of the horizontal branch luminosity in clusters with a wide range of metallicities. Our CCD photometry of the large variable star population of this cluster is used to discuss light curve peculiarities, like Blazhko modulations, on an individual basis. New Blazhko variables are reported. From the RRab stars we found [Fe/H]$_{\rm UVES} = -1.335 \pm 0.003{\rm(statistical)} \pm 0.110{\rm(systematic)}$, and a distance of $7.6\pm 0.2$ kpc, and from the RRc stars we found [Fe/H]$_{\rm UVES}$ = $-1.39 \pm 0.03{\rm(statistical)} \pm 0.12{\rm(systematic)}$ and a distance of $7.5 \pm 0.3$ kpc. The results for RRab and RRc stars should be considered independent since they come from different calibrations and zero points. Absolute magnitudes, radii and masses are also reported for individual RR Lyrae stars. The distance to the cluster was calculated by alternative methods like the P-L relation of SX Phe and the luminosity of the stars at the tip of the red giant branch; we obtained $7.7 \pm 0.4$ and $7.2-7.5$ kpc respectively. The distribution of RR Lyrae stars in the instability strip is discussed and compared with other clusters in connection with the Oosterhoff and horizontal branch type. The Oosterhoff type II clusters systematically show a RRab-RRc segregation about the instability strip first-overtone red edge, while the Oosterhoff type I clusters may or may not display this feature. A group of RR Lyrae stars is identified in an advanced evolutionary stage, and two of them are likely binaries with unseen companions.

description: The quality assessment of multi-crystalline (mc-Si) and high-performance multi-crystalline (HPM)
wafers during incoming inspection of solar cell production requires a reproducible description of the relevant material
defects and a classification scheme which is capable to rate as-cut wafers from unknown manufacturers. Both needs
are addressed in this work. We introduce an image processing framework which allows the various types of
crystallization-related defects visible in photoluminescence images to be detected quantitatively and thus enables a
complete wafer description in terms of defects. The importance of different features within this defect characteristic is
weighted by predicting the open-circuit voltage of solar cells with aluminum back-surface field (Al-BSF) as well as
passivated emitter and rear cells (PERC) with a stepwise extension of the model. The resulting robust classification
scheme is successfully evaluated on a set of 7500 wafers which represents the whole spectrum of material types and
qualities that are currently available at the market. A comparison of defect signatures in HPM and standard mc-Si
materials underlines the relevance of additional features. As a result of this paper we show that a regularized version
of multilinear regression models for quality prediction can optimize simpler linear models by adding selected features
to the defect characteristic leading to mean absolute prediction errors of 2.2 mV for solar cells with Al-BSF and
2.9 mV for PERC solar cells in a true blind test.

Silicon Feedstock, Crystallisation and Wafering

description: 31st European Photovoltaic Solar Energy Conference and Exhibition; 559-563
description: The PV market continues to be dominated by crystalline silicon solar cells which are produced with
polysilicon feedstock. The production of poly-Si is highly energy and cost intensive. SoG-Si has been developed as
an alternative feedstock produced with lower energy consumption and investment cost, but with higher impurity
concentration. The main influence of SoG-Si on ingot and cell performance results from the concentration of dopants
B and P. The presented work investigates the influence of the total dopant concentration on cell efficiency. Industrial
ingots with different feedstock qualities were processed into wafers and cells. A large variation in the total dopant
concentration was achieved by blending the feedstock with poly-Si at different mixing ratios. A significant decrease
in cell efficiency with increasing total dopant concentration was found. It is explained with the dependence of the
electron mobility on the total dopant concentration. Below 3∙1016 cm-3 the influence of the mobility variation on cell
efficiency becomes negligible. To achieve this total dopant concentration P must be below 0,3 ppmw, which is the
case for the new CS SiliconTM GEN2 feedstock. At this level it can be considered as an alternative feedstock to poly-
Si with comparable quality and performance.

description: Emerging studies support the association of gut microbiota, the aggregate of microorganisms within the gastrointestinal (GI) tract, with a range of upper airway diseases through a relationship known as the gut microbiota-airway axis. Asthma, an inflammatory airway disease is growing in frequency among low-income and minority communities; likely due to environmental factors such as consumption of a high-fat, low-fiber western diet. Individuals consuming a western diet likely experience shifts in their GI microbiota, thereby increasing asthmatic risk. We hypothesize that GI microbial metabolism of non-digestible dietary fiber produces anti- inflammatory metabolites such as short-chain fatty acids (SCFAs) which reduce allergic or asthmatic inflammation. Further, we hypothesize that dietary fibers differentially alter the gut microbiota in the ileum (a critical site for immune modulation), the cecum (the site for fiber fermentation), and the colon (a secondary site for fiber fermentation). To test these hypotheses, we performed 16S rRNA gene sequencing on 64 ileum, cecum, and fecal samples from mice maintained on a Western Diet or an ingredient-matched Control Diet and supplemented with placebo or soluble fiber. Microbiome bioinformatics was performed using QIIME 2 to evaluate changes in microbial composition or diversity of the GI microbiota. This project primarily focuses on establishing the effects of diet and fiber supplementation on gut microbiota. Additionally, the goal will be to determine how dietary fibers change the microbiota along different GI niches, advancing our understanding of fiber supplementation on the GI microbiota and respiratory illnesses.

Atom-assisted quadrature squeezing of a mechanical oscillator inside a dispersive cavity

description: We present a hybrid optomechanical scheme to achieve dynamical squeezing of position quadrature of a mesoscopic mechanical oscillator, that can be externally controlled by classical fields. A membrane-in-the-middle set up is employed, in which an atom in $Λ$ configuration is considered to be trapped on either side of the membrane inside the cavity. We show that a considerable amount of squeezing (beyond the 3 dB limit) can be achieved that is not affected by the decay of the cavity and the spontaneous emission of the atom. Squeezing depends upon the initial preparation of atomic states. Further, a strong effective coupling between the atom and the oscillator can be attained by using large control fields that pump the atom and the cavity. Effect of thermal phononic bath on squeezing is studied in terms of the squeezing spectrum. The results are supported by the detailed analytical calculations.

description: We have developed novel Ag and Cu pastes suitable for n-type bifacial PERT (Passivated Emitter and
Rear Totally-diffused) cell. Newly developed NAMICS Ag paste can prevent Ag/Al spikes and contact boron emitter
with low contact resistance. According to SEM measurements of the interface between Ag finger and Si substrate,
any signs of penetration of the Ag paste to boron emitter are not observed. Additionally, low temperature curing Cu
paste has been also developed and applied to both front and rear busbars. As a result, the cell efficiency of our n-type
bifacial PERT solar cell composed of Ag fingers and Cu busbars achieved 20.8 % (Jsc 40.8 mA/cm2, Voc 0.661 V,
F.F. 0.771).

Modeling dynamical scalarization with a resummed post-Newtonian expansion

description: Despite stringent constraints set by astrophysical observations, there remain viable scalar-tensor theories that could be distinguished from general relativity with gravitational-wave detectors. A promising signal predicted in these alternative theories is dynamical scalarization, which can dramatically affect the evolution of neutron-star binaries near merger. Motivated by the successful treatment of spontaneous scalarization, we develop a formalism that partially resums the post-Newtonian expansion to capture dynamical scalarization in a mathematically consistent manner. We calculate the post-Newtonian order corrections to the equations of motion and scalar mass of a binary system. Through comparison with quasi-equilibrium configuration calculations, we verify that this new approximation scheme can accurately predict the onset and magnitude of dynamical scalarization.

description: We show that, for points along the moment curve, the bar-and-joint rigidity matroid and the hyperconnectivity matroid coincide, and that both coincide with the $C^{d-2}_{d-1}$-cofactor rigidity of points along any (non-degenerate) conic in the plane. For hyperconnectivity in dimension two, having the points in the moment curve is no loss of generality. We also show that, restricted to bipartite graphs, the bar-and-joint rigidity matroid is freer than the hyperconnectivity matroid.

Silicon Solar Cell Characterisation and Modelling

description: 31st European Photovoltaic Solar Energy Conference and Exhibition; 485-488
description: In this work we present the results of the contact resistance investigation of high efficiency line
contacted industrial Passivated Emitter and Rear solar Cells (PERC). Especially the homogeneity of the contact
resistance over the rear side of a PERC structure as well as the influence of a high amount of voiding inside the local
rear contacts on the contact resistance is analyzed. The rear contact resistance is measured by the Transfer Length
Method (TLM) and evaluated using our recently developed evaluation method utilizing 2D Sentaurus Device
simulations of the sample structure. These evaluations yield a low mean specific rear contact resistance and
demonstrate that it is homogeneously distributed over the rear side of a PERC solar cell even for a high percentage of
rear contact voiding above 60%. The reason for the voiding to have little effect on the contact resistance is that
Scanning Electron Microscopy (SEM) and Energy-Dispersive X-ray spectroscopy (EDX) images reveal a
metallization along the edges of voided rear contacts. By applying our cell processes and screen-printing pastes this
edge metallization is sufficient to achieve an adequate electrical connection between the base and the rear
metallization of actual high efficiency PERC solar cells.

Silicon Solar Cell Characterisation and Modelling

description: 31st European Photovoltaic Solar Energy Conference and Exhibition; 489-494
description: We present a procedure to simulate hundreds of solar cells per second. The procedure is suited to solar
cell factories because their cells are fabricated from a wide range of silicon wafers and because there is significant
variation within each manufacturing step. Consequently, a batch of industrial solar cells tends to have a wide
distribution of critical properties, such as resistivity, lifetime, dopant profiles, and surface recombination, to name a
few. A realistic simulation of a factory’s efficiency distribution therefore requires the simulation of a large number of
individual cells. This paper describes a very fast method to simulate a solar cell in one dimension. It yields the same
efficiency as PC1D to within ±0.1% (absolute) and it is 10–100 times faster to solve. We present the computation time
of each step in the procedure and evaluate the relationship between accuracy, speed, and the number of nodes.
