 Oral Presentation Reconstruction of a mutualistic symbiosis between Arabidopsis thaliana & Colletotrichum tofieldiae Johannes {Jan} Gärtner Universität Köln, Germany; johannes.gaertner@uni-koeln.de Arbuscular mycorrhizal symbiosis (AMS) is one of the oldest extant plant-microbe associations, which most likely even played a key role in plant terrestrialisation ~400 Mya ago (Bago, 2000). When the mycorrhizal host plant perceives low phosphate deficiency conditions in the soil, it triggers a phosphate deficiency response (PSR) that prompts the establishment of symbiosis to gain access to inorganic phosphate in the soil. Notwithstanding the benefits of nutrient exchange, AMS requires the plant to release carbon assimilates to its fungal symbiont. It is probably this energy cost to the host associated with AM fungi (AMF) that has led to the loss of AMS in some plant species during evolution. Brassicaceae are AMF non-hosts and so is the most commonly used model plant, Arabidopsis thaliana. Furthermore, many AMF are difficult to cultivate because of their obligate biotrophy. A. thaliana is thus a non-host for AMF, which is a significant complication for research into the molecular mechanisms underlying AMS. On the other hand, A. thaliana forms a mutualistic relationship with Colletotrichum tofieldiae. C. tofieldiae is a facultatively free-living ascomycete from a well-studied genus that includes many plant pathogens. In addition, C. tofieldiae is readily cultivable and transformable (Hiruma et al., 2016) and therefore proves to be a viable system for investigating the molecular and genetic basis of root endophytism in A. thaliana. In my project, C. tofieldiae is genetically engineered to function as an obligate symbiont of A. thaliana by establishing fatty acid auxotrophy. The immediate question to be answered is whether the bidirectional exchange of inorganic phosphate from the fungus and fatty acids from the plant occurs in reciprocity. By strengthening the synthetic symbiotic partnership established in this project, it will be possible to identify both plant and fungal traits that will enable us to construct specific mutualistic symbioses that improve host plant growth and fitness.

description: Novel braneworld scenarios supported by warp factors driven by a single extra dimension are obtained from deformed one-dimensional lump-like solutions known {\em a priori}. Through a novel {\em ansatz}, the internal energy structure, the braneworld warp factor, and the quantum mechanical analogue problem, as well as the associated zero mode solutions, are straightforwardly derived by means of an analytical procedure. The results allow one to identify thick brane solutions that support internal structures and that can hold the ($3+1$)-dimensional gravity.

description: We measure the branching ratios from the $y^8{\rm P}_{9/2}$ excited state to six metastable states of europium through fluorescence spectroscopy of an atomic beam. The sum of the six branching ratios is estimated to be $1.05(2)\times 10^{-3}$. This research provides us with insightful information to determine the feasibility of using the $a^8{\rm S}_{7/2} - y^8{\rm P}_{9/2}$ transition in order to implement the Zeeman slowing for europium atoms in the ground state. Based on this result, we also propose a scheme for Zeeman slowing and magneto-optical trapping, using a specific metastable state which has a cyclic transition.

description: The recent development of brand new observational techniques and theoretical models have greatly advanced the exoplanet research field. Despite significant achievements, which have allowed the detection of thousands extrasolar systems, a comprehensive understanding of planetary formation and evolution mechanisms is still desired. One relevant limitation is given by the accuracy in the measurements of planet-host star ages. The star GJ 504 has been found to host a substellar companion whose nature is strongly debated. There has been a recent difference of opinion in the literature owing to the uncertainty on the age of the system: a young age of $\sim$ 160 Myr would imply a giant planet as a companion, but a recent revision pointing to a solar age ($\sim$ 4 Gyr) instead suggests a brown dwarf. With the aim of shedding light on this debated topic, we have carried out a high-resolution spectroscopic study of GJ 504 to derive stellar parameters, metallicity, and abundances of both light and heavy elements, providing a full chemical characterisation. The main objective is to infer clues on the evolutionary stage (hence the age) of this system. We performed a strictly differential (line-by-line) analysis of GJ 504 with respect to two reference stars, that is the planet-host dwarf $ι$ Hor and the subgiant HIP 84827. The former is crucial in this context because its stellar parameters (hence the evolutionary stage) is well constrained from asteroseismic observations. Regardless of the zero point offsets, our differential approach allows us to put tight constraints on the age of GJ 504 with respect to $ι$ Hor, thereby minimising the internal uncertainties. We found that the surface gravity of GJ 504 is 0.2 $\pm$ 0.07 dex lower than that of the main-sequence star $ι$ Hor, suggesting a past turn-off evolution[...]

description: Early access to technological knowledge embodied in an industry's innovation network can prove an important competitive advantage for firms. Surprisingly, not much is known about the determinants of their initial entry into such networks. We analyze the propensity of firms for entering the industry’s innovation network and their timing in doing so. More precisely, we seek to shed some light on the factors affecting the length of the time-span between a firm’s founding and its first cooperation event. We apply a unique longitudinal event history dataset based on the full population of German laser source manufacturers. Innovation network data stem from official databases providing detailed information on the organizations involved, the subject of joint research and development (R&D) efforts, as well as the start and end times of all publicly funded R&D projects between 1990 and 2010. Estimation results from an event history estimation model indicate that micro firms enter the network later than small or large firms. An in-depth analysis of the size effects for medium-sized firms provides some unexpected but highly interesting findings. The choice of cooperation type makes no significant difference to a firm’s timing in entering the network. Finally, the analysis of geographical determinants shows that cluster membership can, but does not necessarily affect the timing of a firm’s decision to cooperate.
Investigating the relation between pre-service teachers' argumentative writing and knowledge integration when learning with multiple texts

description: Recent research shows that learning tasks which require students to consult multiple sources and write an argumentative essay promote the cognitive integration of knowledge and ideas presented in the source documents. This study examines whether this holds true in pre-service teacher education, which asks for an integration of knowledge and ideas from conceptually distinct and mainly separately taught knowledge domains (i.e., content knowledge (CK), pedagogical knowledge (PK), and pedagogical content knowledge (PCK)). Forty-six pre-service teachers received domain-specific textbook excerpts, each representing either CK, PK, or PCK, and an argument writing task. The students read the texts and wrote argumentative essays on how the content provided in the source documents is related as regards teaching. Using structural and analytic methods to investigate the argumentative essays it was found that students’ argumentative writing was related to knowledge integration across domains. The generation and inclusion of warrants and the developed connectivity and causality in students’ essays appeared particularly important for their knowledge integration. The findings are discussed with regard to how certain instructional scaffolds can support pre-service teachers’ argumentative reasoning/writing to enhance knowledge integration across domains. Some directions for future research are drawn.

description: Diese Arbeit befasst sich mit dem Einlaufverhalten amorpher Kohlenstoffschichten in einem geschmierten Tribosystem mit einem metallischen Gegenkörper. Es wurde untersucht, inwiefern sich Reibung und Verschleiß in Abhängigkeit von der Abfolge der Belastung und der Endbearbeitung der amorphen Schichten entwickeln. Dazu wurden Versuche in einem Stift-Scheibe-Tribometer mit Echtzeitverschleißmessung (RNT) im Mischreibungszustand durchgeführt. Die Messungen zeigen einen ausgeprägten Einlauf, vergleichbar zu einem Metall-Metall-Tribosystem, der von hoher, initialer Belastung profitiert. Für die Endbearbeitung gibt es einen schmalen Korridor, in dem sich kleinste Reibwerte und Verschleißraten einstellen. Mittels mehrerer Analyseverfahren konnte gezeigt werden, dass der Einlauf zu einer Anreicherung des sp²-Gehalts in der Randzone führt.

description: Since SS camp personnel obeyed the strict prohibition against photography in Nazi annihilation, concentration, and work camps, the footage that Allied cameramen shot in such camps during and shortly after their liberation filled this void in visual documentation. Thus, what we imagine went on in Nazi camps while in operation has been shaped by pictures that document their very last stages. So, though the arrival of Allied soldiers was a turning point for survivors, the film that Allied cameramen shot in those days tells us more about the effects of Nazi terror than about survivors’ liberation from it.

description: The discovery of iron pnictides and iron chalcogenides as a new class of unconventional superconductors in 2008 has generated an enourmous amount of experimental and theoretical work that identifies these materials as correlated metals with multiorbital physics, where magnetism, nematicity and superconductivity are competing phases that appear as a function of pressure and doping. A microscopic understanding of the appearance of these phases is crucial in order to determine the nature of superconductivity in these systems. Here we review our recent theoretical efforts to describe and understand from first principles the properties of iron pnictides and chalcogenides with special focus on (i) pressure dependence, (ii) effects of electronic correlation and (iii) origin of magnetism and superconductivity.

description: Dynamic electrochemical impedance spectroscopy (DEIS) has attracted the interest of researchers due to its capability of acquiring impedance spectra of non-stationary systems in a broad range of frequencies. Although developed in the 70's, a physical definition of dynamic impedance, and in general of dynamic transfer function, is not present in literature. In this manuscript the general concept of dynamic frequency response is given in correlation to the Volterra series expansion: this can be used to define the ideal dynamic impedance response of an electrochemical system. It is clarified that DEIS is the intermodulation of the ac signal with the dc signal. Starting from this, different strategies for the extraction of the dynamic impedance spectra are compared, which are based on different heuristic definitions of DEIS. There are two main methodologies, one based on the use of window functions and the other on quadrature filters. Limits and merits of the different methodologies are discussed in the frame of the data analysis and data handling and show that window functions suffers at recovering low-frequencies impedances while quadrature filters work best in experiments which have a periodic or quasi-periodic trend.

description: Understanding users' interactions with highly subjective content---like artistic images---is challenging due to the complex semantics that guide our preferences. On the one hand one has to overcome `standard' recommender systems challenges, such as dealing with large, sparse, and long-tailed datasets. On the other, several new challenges present themselves, such as the need to model content in terms of its visual appearance, or even social dynamics, such as a preference toward a particular artist that is independent of the art they create. In this paper we build large-scale recommender systems to model the dynamics of a vibrant digital art community, Behance, consisting of tens of millions of interactions (clicks and `appreciates') of users toward digital art. Methodologically, our main contributions are to model (a) rich content, especially in terms of its visual appearance; (b) temporal dynamics, in terms of how users prefer `visually consistent' content within and across sessions; and (c) social dynamics, in terms of how users exhibit preferences both towards certain art styles, as well as the artists themselves.

description: Der Architekturdiskurs begegnet der Natur mit Skepsis. Jenseits schöner Landschaften wird die Suche nach dem Wesen der Natur durch die allgemeine Popularität des Begriffs erschwert. Dies wird befördert durch eine Baugeschichte, welche die Baukunst traditionell als statischen Gegenpunkt zu einer Natur begriffen versteht, die seit der Antike als etwas in seinem Wesen Dynamisches und Prozesshaftes gedacht wird. Die Architektur spiegelt hier eine allgemeine Tendenz wider: Obwohl wir als leibliche Wesen doch Teil der Natur sind, haben wir uns im Lauf der Geschichte immer mehr als ihr Gegenüber betrachtet. – Naturphilosophische Ansätze versuchen diese Kluft immer wieder zu überwinden.

The implication of the blue-tilted spectrum, $n_t>0$, of the primordial tensor fluctuations is discussed for the reconstructed configurations of the scalar field potential and the Gauss-Bonnet coupling.

We scrutinize this by an estimation approach combining panel model and time series characteristics and using regional data for the years 1980 to 2014. The results show that innovation and innovation subsidies in the long run have a positive impact on the economic development of regions in Germany. This supports a long-term strategy for regional and innovation policy.

description: In this study, we systematically investigate 3D momentum($\hbar k$)-resolved electronic structures of Ruddlesden-Popper-type iridium oxides Sr$_{n+1}$Ir$_n$O$_{3n+1}$ using soft-x-ray (SX) angle-resolved photoemission spectroscopy (ARPES). Our results provide direct evidence of an insulator-to-metal transition that occurs upon increasing the dimensionality of the IrO$_2$-plane structure. This transition occurs when the spin-orbit-coupled $j_{\rm eff}$=1/2 band changes its behavior in the dispersion relation and moves across the Fermi energy. In addition, an emerging band along the $Γ$(0,0,0)-R($π$,$π$,$π$) direction is found to play a crucial role in the metallic characteristics of SrIrO$_3$. By scanning the photon energy over 350 eV, we reveal the 3D Fermi surface in SrIrO$_3$ and $k_z$-dependent oscillations of photoelectron intensity in Sr$_3$Ir$_2$O$_7$. In contrast to previously reported results obtained using low-energy photons, folded bands derived from lattice distortions and/or magnetic ordering make significantly weak (but finite) contributions to the $k$-resolved photoemission spectrum. At the first glance, this leads to the ambiguous result that the observed $k$-space topology is consistent with the unfolded Brillouin zone (BZ) picture derived from a non-realistic simple square or cubic Ir lattice. Through careful analysis, we determine that a superposition of the folded and unfolded band structures has been observed in the ARPES spectra obtained using photons in both ultraviolet and SX regions. To corroborate the physics deduced using low-energy ARPES studies, we propose to utilize SX-ARPES as a powerful complementary technique, as this method surveys more than one whole BZ and provides a panoramic view of electronic structures.

For example, a user may have a diversity vector of a genotype of interest and wish to find the phylogenetically closest genebank material from a particular geographical region or with particular traits. To increase the power of the analysis, an imputation service called DivImpute is developed. This will increase the marker density and enrich the input for the subsequent phylogenetic similarity search.

description: The EXtreme PREcision Spectrograph (EXPRES) is an optical fiber fed echelle instrument being designed and built at the Yale Exoplanet Laboratory to be installed on the 4.3-meter Discovery Channel Telescope operated by Lowell Observatory. The primary science driver for EXPRES is to detect Earth-like worlds around Sun-like stars. With this in mind, we are designing the spectrograph to have an instrumental precision of 15 cm/s so that the on-sky measurement precision (that includes modeling for RV noise from the star) can reach to better than 30 cm/s. This goal places challenging requirements on every aspect of the instrument development, including optomechanical design, environmental control, image stabilization, wavelength calibration, and data analysis. In this paper we describe our error budget, and instrument optomechanical design.

description: In this paper we investigate the impact of regional and technological innovation systems on innovation cooperation. We develop an indicator applicable to regions, which demonstrates the relative regional impact on innovation cooperation. Applying this method to German patent data, we find that regional differences in the degree of innovation cooperation do not only depend on the technology structure of a region but also on specific regional effects. High-tech oriented regions, whether east or west, are not automatically highly cooperative regions. East German regions have experienced a dynamic development of innovation cooperation since re-unification in 1990. Their cooperation intensity remains higher than in West German regions.

description: Gamma ray bursts (GRBs) are classified into long and short categories based on their durations. Broad band studies suggest that these two categories of objects roughly correspond to two different classes of progenitor systems, i.e. compact star mergers (Type I) vs. massive star core collapse (Type II). However, the duration criterion sometimes leads to mis-identification of the progenitor systems. We perform a comprehensive multi-wavelength comparative study between duration-defined long GRBs and short GRBs as well as the so-called "consensus" long GRBs and short GRBs (which are believed to be more closely related to the two types of progenitor systems). The parameters we study include two parts: the prompt emission properties including duration ($T_{90}$), spectral peak energy ($E_{\rm p}$), low energy photon index ($α$), isotropic $γ$-ray energy ($E_{\rm γ, iso}$), isotropic peak luminosity ($L_{\rm p,iso}$), and the amplitude parameters ($f$ and $f_{\rm eff}$); and the host galaxy properties including stellar mass ($M_*$), star formation rate (SFR), metallicity ([X/H]), half light radius ($R_{50}$), angular and physical ($R_{\rm off}$) offset of the afterglow from the center of the host galaxy, the normalized offset ($r_{\rm off}=R_{\rm off}/R_{50}$), and the brightness fraction $F_{\rm light}$. For most parameters, we find interesting overlapping properties between the two populations in both 1D and 2D distribution plots. The three best parameters for the classification purpose are $T_{90}$, $f_{\rm eff}$, and $F_{\rm light}$. However, no single parameter alone is good enough to place a particular burst into the right physical category, suggesting a need of multiple criteria for physical classification.

description: CMOS imagers are becoming increasingly popular in astronomy. A very low noise level is required to observe extremely faint targets and to get high-precision flux measurements. Although CMOS technology offers many advantages over CCDs, a major bottleneck is still the read noise. To move from an industrial CMOS sensor to one suitable for scientific applications, an improved design that optimizes the noise level is essential. Here, we study the 1/f and thermal noise performance of the source follower (SF) of a CMOS pixel in detail. We identify the relevant design parameters, and analytically study their impact on the noise level using the BSIM3v3 noise model with an enhanced model of gate capacitance. Our detailed analysis shows that the dependence of the 1/f noise on the geometrical size of the source follower is not limited to minimum channel length, compared to the classical approach to achieve the minimum 1/f noise. We derive the optimal gate dimensions (the width and the length) of the source follower that minimize the 1/f noise, and validate our results using numerical simulations. By considering the thermal noise or white noise along with 1/f noise, the total input noise of the source follower depends on the capacitor ratio CG/CFD and the drain current (Id). Here, CG is the total gate capacitance of the source follower and CFD is the total floating diffusion capacitor at the input of the source follower. We demonstrate that the optimum gate capacitance (CG) depends on the chosen bias current but ranges from CFD/3 to CFD to achieve the minimum total noise of the source follower. Numerical calculation and circuit simulation with 180nm CMOS technology are performed to validate our results.

description: Assessing the benefits of crop diversification – a pillar of the agroecological transition – on a large scale requires a description of current crop sequences as a baseline, which is lacking at the scale of the European Union (EU). This work is based on the Harmonised LUCAS in-situ land cover and use database for field surveys from 2006 to 2018 in the European Union (doi: 10.2905/f85907ae-d123-471f-a44a-8cca993485a2) to fill this gap, We completed this dataset with a crop sequence type information for each point under non-perennial agricultural land cover in 2012, 2015 and 2018. Here is the code used to produce the harmonised LUCAS database classified by crop sequence type (10.5281/zenodo.7016986), for quality assessment and for creating figures and tables. - 1_LUCASD_formating.R selects points under non-perennial agricultural land-cover from harmonised LUCAS database. It calculates (groups of) crops temporal frequencies within the crop sequence for each point ; - 2_LUCAS_classification.R classifies each point previously seleced into eight crop sequence types, thanks to hierachical clustering : - 3_randomForest_classifier.R trains a random forest model on the LUCAS classified dataset, to predict crop sequence type from (groups of) crops frequencies within crop sequence ; - 4_LPIS_assignation.R assigns crop sequence type to each field from the French LPIS dataset, which is used later for quality assessment ; - 5_validation_national_scale.R compares crop sequence types distribution for France from the LUCAS classified dataset - which is spatially and temporally-incomplete - against the French LPIS dataset - which is spatially and temporally almost exhaustive ; - 6_validation_regional_scale.R compares crop sequence types distribution for each French administrative region from the LUCAS classified dataset against the French LPIS dataset ; - 7_validation_eu_scale.R compares (groups of) crops area estimated for each EU country from LUCAS classified dataset, against areas known from EUROSTAT official statistics : - 8_crop_sequences_mapping.R creates maps of crop sequence types at the scale of the EU ; - 9_crop_sequences_distribution.R create figure of crop sequence types distribution regarding latitude.

description: We derive and employ a local potential to represent the Fock exchange operator in electronic single-particle equations. This local Fock-exchange (LFX) potential is very similar to the exact exchange (EXX) potential in density functional theory (DFT). The practical software implementation of the two potentials (LFX and EXX) yields robust and accurate results for a variety of systems (semiconductors, transition metal oxides) where Hartree Fock and popular approximations of DFT typically fail. This includes examples traditionally considered qualitatively inaccessible to calculations that omit correlation.

description: Sie nennen sich Soundcloud, Researchgate, 6Wunderkinder oder Zalando - junge Gründer, die das Internet im Rahmen ihrer Geschäftsideen auf vielfältige Weise nutzen, zieht es nach Berlin. Nationale Gründerstatistiken zeigen, dass sich Internetunternehmen nirgendwo besser gründen lassen als in Berlin, Hamburg oder München. Allerdings finden Hamburg und München in der medialen Berichterstattung kaum Beachtung. Mit viel Hysterie und Enthusiasmus rufen Medien und Blogs stattdessen die Bundeshauptstadt als Start-up-Metropole der Zukunft aus. Doch warum ist das so? Wonach suchen digitale Existenzgründer in Berlin, was sie an anderen IT-Gründerhochburgen wie Hamburg oder München nicht finden? Warum konzentrieren sich Web- und Softwareunternehmen an einem Standort wie diesen? Antworten darauf gibt eine diskursanalytische Untersuchung der drei wichtigsten deutschsprachigen Gründer-Blogs. Die Ergebnisse zeigen, dass Berlin spezielle Standortansprüche der Gründer von Internetunternehmen bedient. Insgesamt identifiziert die Diskursanalyse drei zentrale Anforderungsbereiche: Die lokale Verfügbarkeit von Wagniskapital, die dortige Internationalität sowie ein szene-basiertes Ökosystem und sozio-kulturelles Raumangebot.

description: This paper mainly investigates the approximation of a global maximizer of the 1-D Monge-Kantorovich mass transfer problem through the approach of nonlinear differential equations with Dirichlet boundary. Using an approximation mechanism, the primal maximization problem can be transformed into a sequence of minimization problems. By applying the canonical duality theory, one is able to derive a sequence of analytic solutions for the minimization problems. In the final analysis, the convergence of the sequence to a global maximizer of the primal Monge-Kantorovich problem will be demonstrated.
