description: Petal color is one of the key characteristics determining the attractiveness and therefore the commercial value of an ornamental crop. Here, we present the first genome-wide association study for the important ornamental crop rose, focusing on the anthocyanin and carotenoid contents in petals of 96 diverse tetraploid garden rose genotypes. Cultivated roses display a vast phenotypic and genetic diversity and are therefore ideal targets for association genetics. For marker analysis, we used a recently designed Axiom SNP chip comprising 68,000 SNPs with additionally 281 SSRs, 400 AFLPs and 246 markers from candidate genes. An analysis of the structure of the rose population revealed three subpopulations with most of the genetic variation between individual genotypes rather than between clusters and with a high average proportion of heterozygous loci. The mapping of markers significantly associated with anthocyanin and carotenoid content to the related Fragaria and Prunus genomes revealed clusters of associated markers indicating five genomic regions associated with the total anthocyanin content and two large clusters associated with the carotenoid content. Among the marker clusters associated with the phenotypes, we found several candidate genes with known functions in either the anthocyanin or the carotenoid biosynthesis pathways. Among others, we identified a glutathione-S-transferase, 4CL, an auxin response factor and F3’H as candidate genes affecting anthocyanin concentration, and CCD4 and Zeaxanthine epoxidase as candidates affecting the concentration of carotenoids. These markers are starting points for future validation experiments in independent populations as well as for functional genomic studies to identify the causal factors for the observed color phenotypes. Furthermore, validated markers may be interesting tools for marker-assisted selection in commercial breeding programmes in that they provide the tools to identify superior parental combinations that combine several associated markers in higher dosages.

description: We present a High-Pressure X-ray Photoelectron Spectroscopy (HP-XPS) and first-principles kinetic Monte Carlo study addressing the nature of the active surface in CO oxidation over Pd(100). Simultaneously measuring the chemical composition at the surface and in the near-surface gas-phase, we reveal both O-covered pristine Pd(100) and a surface oxide as stable, highly active phases in the near-ambient regime accessible to HP-XPS. Surprisingly, no adsorbed CO can be detected during high CO2 production rates, which can be explained by a combination of a remarkably short residence time of the CO molecule on the surface and mass-transfer limitations in the present set-up.

description: Further advances in the field of ultrafast magnetization dynamics require experimental tools to measure the spin and electron dynamics with element-specificity and femtosecond temporal resolution. We present a new laboratory setup for two complementary experiments with light in the extreme ultraviolet (XUV) spectral range. One experiment is designed for polarization-dependent transient spectroscopy, particularly for simultaneous measurements of magnetic circular dichroism (MCD) at the 3p resonances of the 3d transition metals Fe, Co, and Ni. The second instrument is designed for resonant small-angle scattering experiments with monochromatic light allowing us to monitor spin dynamics with spatial information on the nanometer scale. We combine a high harmonic generation (HHG) source with a phase shifter to obtain XUV pulses with variable polarization and a flux of about (3 ± 1) × 1010 photons/s/harmonic at 60 eV at the source. A dedicated reference spectrometer effectively reduces the intensity fluctuations of the HHG spectrum to below 0.12% rms. We demonstrate the capabilities of the setup by capturing the energy- and polarization-dependent absorption of a thin Co film as well as the time-resolved small-angle scattering in a magnetic-domain network of a Co/Pt multilayer. The new laboratory setup allows systematic studies of optically induced spin and electron dynamics with element-specificity, particularly with MCD as the contrast mechanism with femtosecond temporal resolution and an unprecedented signal-to-noise ratio.

description: Gegenstand der vorliegenden Untersuchung ist der Freundschaftsbegriff der Renaissance der seinen Ursprung wesentlich in der antiken Philosophie hat seine Darstellungsweisen in der europäischen (insbesondere der englischen und italienischen) Literatur des fünfzehnten und sechzehnten Jahrhunderts und der Wandel dem dieser beim Epochenwechsel zur Aufklärung im siebzehnten Jahrhundert unterworfen war. Meine Arbeit vertritt die Hypothese dass sich die Konzeptionen der verschiedenen Formen zwischenmenschlicher Beziehung die sich spätestens seit dem achtzehnten Jahrhundert etablieren konnten auf die konzeptionellen Veränderungen des Freundschaftsbegriffs und insbesondere auf den Wandel des Begriffsverständnisses von Freundschaft und Liebe während der Renaissance und des sich anschließenden Epochenwechsels zurückführen lassen. Um diese Hypothese zu verifizieren habe ich daher nach einer kurzen Übersicht über die konzeptionellen Ursprünge des frühneuzeitlichen Freundschaftsbegriffs zunächst das Wesen der primär auf den philosophischen Idealen der antiken Denker beruhenden Freundschaftskonzeption der Renaissance analysiert. Hierbei ließ sich eine grundlegende Disparität zwischen den klassisch inspirierten Idealvorstellungen und deren realer Umsetzung in der frühen Neuzeit nachweisen die sich im weiteren Verlauf als mit ursächlich für die weitere Entwicklung des Freundschaftsbegriffs herausstellen sollte.

description: Standard integration schemes for rate constitutive equations were designed within the classical theory of plasticity. Consequently, they rely on the assumption that a yield criterion defines a range of purely elastic material behaviour. Many constitutive models for non-cohesive soils discard that assumption. They account for inelastic deformations without employing a yield criterion. This simplifies the formulation of the models but raises questions concerning their numerical implementation. In particular, it is not fully clear which algorithmic method is most appropriate for the numerical integration of constitutive models without elastic range. To investigate this, two different stress point algorithms for a critical state bounding surface model for sands were developed and implemented. The explicit method employs substepping to automatically control the local error. The implicit method updates stresses and state variables through a local Newton iteration, the Jacobian of which is computed by numerical differentiation. The two algorithms were compared by means of calculations at integration point level as well as with respect to a boundary value problem. The results show that for a given level of accuracy, the explicit update procedure is significantly more efficient than the implicit one. This holds regardless of initial state parameters and input strain increment magnitudes.

description: Global water scarcity is a growing international concern due to its implications for human survival. Freshwater can be considered a fundamental resource integral to our ecological and societal activities. The Freshwater-rising demand and shifting supply of freshwater in parallel with uneven and irregular distributed, are a source of significant friction among countries. Furthermore, unsustainable management practices can lead to substantial conflict among countries and communities as they attempt to secure their share, which can easily trigger violent confronta?tions (Gleick 1993; Michel 2020). Water availability has particular connotations in the Middle East; as water has emerged as a strategic resource that fuels disagreement and can easily translate into armed conflict.

description: Several constitutive models for sands are based on an additive split of the effective stress rate into two terms. One term accounts for the deviatoric stress ratio rr, the other for the mean effective stress p. While sophisticated techniques are available to account for monotonic and cyclic variations of rr, the p term is usually treated by means of rather rudimentary constitutive mechanisms. In particular, no plasticity sand model seems to exist whose functions take into account cyclic changes of p in a realistic manner. However, cyclic changes of p frequently occur in geotechnical boundary value problems and can cause irrecoverable deformation in non-cohesive soils. Present sand models significantly under- or overestimate these deformations. This issue is tackled in the paper. First, results from a comprehensive series of triaxial tests on Toyoura Sand are presented. The samples were loaded with cyclic changes of p at constant stress ratio in order to study the effects of mean effective stress variations exclusively. The test results show that the samples accumulate significant irrecoverable strains throughout successive loading cycles. The results furthermore allow to investigate the effects of pressure level, pressure amplitude, stress ratio level and density on the strain evolution. Second, new constitutive functions for an existing Bounding Surface Plasticity model are proposed in the paper. They are intended to improve the simulation results obtained with the model for monotonic and cyclic changes of p at constant stress ratio. The extended model is then carefully calibrated and validated using the experimental data from the triaxial tests. The results of the validation prove that the new constitutive functions have the desired effect.

Year: 2018

description: This article revisits the question of ‘la bêtise’ or stupidity in the era of Artificial Intelligence driven by Big Data, it extends on the questions posed by Gille Deleuze and more recently by Bernard Stiegler. However, the framework for revisiting the question of la bêtise will be through the lens of contemporary computer science, in particular the development of data science as a mode of analysis, sometimes, misinterpreted as a mode of intelligence. In particular, this article will argue that with the advent of forms of hype (sometimes referred to as the hype cycle) in relation to big data and modalities of data analytics there is a form of computational stupidity or functional stupidity at work. The exaggerated promises of big data to solve everything are overblown expectations which will lead ultimately to a form of disillusionment with data science. This can be seen in a number of domains, for example smart city technologies, the internet of things, and machine translation. In addition to the negative effects of exaggerated claims of Big Data is the possibility that societal norms will facilitate Big Data technological change by incorporating the bêtise of Big Data, thus leading to a change in our relationship to technology, examples of this would be privacy standards and ownership of data. This paper will conclude by setting out the analysis some of the limitations of Artificial intelligence and Big Data in order to allow a re-examination of the claims made.

description: This thesis analyses several political economy mechanisms surrounding economic development and development cooperation. In Chapter 1, I show that foreign policy alignment changes following leader changes in both recipient and donor countries impact the allocation of Official Development Aid. In addition, I highlight that leader changes are a natural breaking point for bilateral relations that make usually inconsequential actions matter. In Chapter 2, I find that development aid affects civil conflict dynamics within recipient countries in previously unknown ways. Aid seems to have an escalating effect on civil conflict during episodes of minor violence, but no effect on civil conflict once violence is widespread. In Chapter 3, I analyze the effect of territorial decentralization and centralization on economic development in a global sample of primary subnational units. I show that the economic benefits of these reforms are very context-specific. Centralization reforms increase economic development in Africa, while decentralization reforms have been successful in Asia. Additionally, there are differential effects within treated areas. Centralization reforms are less beneficial for areas that move to the political periphery, while decentralization yields bigger economic payoffs in countries that have local accountability in the form of local elections. Chapter 4 turns the focus to OECD countries and analyses how international migration affects the probability of terrorism. Even though increases in the foreign-born population increase the risk of terrorism, the effect is indistinguishable from increases in the native-born population. What is more, restricting the rights of migrants does not diminish but increase the effect of migrants on terror. In summary, the thesis highlights that several political economy mechanisms in the context of development and political conflict are much more context and time dependent than previously thought.

description: The temperature-dependent diffusion coefficients of interstitial helium atom in $α$-Ti are predicted using the transition state theory. The microscopic parameters in the pre-factor and activation energy of the impurity diffusion coefficients are obtained from first-principles total energy and phonon calculations including the full coupling between the vibrational modes of the diffusing atom and the host lattice. The climbing image nudged elastic band (CINEB) method is used to search for the minimum energy pathways and associated saddle point structures. It is demonstrated that the diffusion coefficients within the \emph{xy} plane ($D_{xy}$) is always higher than that along the \emph{z} axis ($D_{z}$), showing remarkable anisotropy. Also, it is found that the formation of helium dimer centered at the octahedral site reduces the total energy and confines the diffusion of helium atoms.

description: This paper applies recent results on the robust stability of nonlinear quantum systems to the case of a Josephson junction in a resonant cavity. The Josephson junction is characterized by a Hamiltonian operator which contains a non-quadratic term involving a cosine function. This leads to a sector bounded nonlinearity which enables the previously developed theory to be applied to this system in order to analyze its stability.

description: All organisms are frequently exposed to changing environmental conditions in their natural habitat, which can impose stress and threatens basic biological functions. To cope with such adverse conditions, cells have developed complex stress response systems which allow the sensing and integration of envi- ronmental stress signals and the regulation of appropriate responses. For example, a sudden temperature upshift and other proteotoxic conditions which facilitate the misfolding and aggregation of cellular pro- teins, activate the heat shock response. This global transcriptional response mediates a concerted up- regulation and accumulation of conserved chaperones and proteases, the protein quality control system, to restore and maintain protein homeostasis during stress. Another fast-acting bacterial stress response program, the stringent response, is activated upon amino acid starvation and many other stress signals. It is regulated by the second messenger nucleotide (p)ppGpp, which mediates the transcriptional repres- sion of ribosomal genes while activating stress response- and amino acid synthesis genes, but also causes the inhibition of translation, replication and interferes with other processes. In this thesis, the heat shock response of the Gram positive model organism Bacillus subtilis was studied. It could be demonstrated that the transcriptional regulator Spx is not only a central regulator of many heat shock response genes, but can also participate in the transcriptional down-regulation of rRNA and ribosomal protein genes, which were observed to be strongly down-regulated during many stress conditions. In addition, it could be demonstrated, that the stringent response mediated by (p)ppGpp is activated during the heat shock response. Increased (p)ppGpp levels conferred elevated heat stress re- sistance while the lack of (p)ppGpp renders cells more sensitive to stress. Remarkably, it appears that both (p)ppGpp and Spx are concurrently involved in the down-regulation of rRNA genes during heat stress. Furthermore, the results suggest that (p)ppGpp is involved in direct adjustments of translation during stress, which appears to be crucial for the protective role of the stringent response in the heat stress response. Together, the results suggest a model by which the heat shock response of B. subtilis not only involves the synthesis and accumulation of chaperones and proteases of the protein quality control system but also the concurrent curbing of the protein synthesis rate by (p)ppGpp to support protein homeostasis by reducing the load for the cellular protein quality control system.

Hydrogen-loosing planets in transition discs around young protostars

description: We point out that protoplanets created in the framework of the Tidal Downsizing (TD) theory for planet formation play a very important role for the evolution of accretion discs hosting them. Since all TD protoplanets are initially as massive as $\sim 10$ Jupiter masses, they are able to open very deep gaps in their discs, and even completely isolate the inner disc flows from the outer ones. Furthermore, in contrast to other planet formation theories, TD protoplanets are mass donors for their protostars. One potentially observable signature of planets being devoured by their protostars are FU Ori like outbursts, and episodic protostar accretion more generally, as discussed by a number of authors recently. Here we explore another observational implication of TD hypothesis: dust poor inner accretion flows, which we believe may be relevant to some of the observed mm-bright transitional discs around protostars. In our model, a massive protoplanet interrupts the flow of the outer dust-rich disc on its protostar, and at the same time looses a part of its dust-poor envelope into the inner disc. This then powers the observed gas-but-no-dust accretion onto the star. Upon a more detailed investigation, we find that this scenario is quite natural for young massive discs but is less so for older discs, e.g., those whose self-gravitating phase has terminated a fraction of a Million year or more ago. This stems from the fact that TD protoplanets of such an age should have contracted significantly, and so are unlikely to loose much mass. Therefore, we conclude that either (i) the population of "transition discs" with large holes and dust-poor accretion is much younger than generally believed; or (ii) there is a poorly understood stage for late removal of dust-poor envelopes from TD planets; (iii) another explanation for the observations is correct.

description: Network inference approaches are widely used to shed light on regulatory interplay between molecular players such as genes and proteins. Biochemical processes underlying networks of interest (e.g. gene regulatory or protein signalling networks) are generally nonlinear. In many settings, knowledge is available concerning relevant chemical kinetics. However, existing network inference methods for continuous, steady-state data are typically rooted in statistical formulations, which do not exploit chemical kinetics to guide inference. Herein, we present an approach to network inference for steady-state data that is rooted in non-linear descriptions of biochemical mechanism. We use equilibrium analysis of chemical kinetics to obtain functional forms that are in turn used to infer networks using steady-state data. The approach we propose is directly applicable to conventional steady-state gene expression or proteomic data and does not require knowledge of either network topology or any kinetic parameters. We illustrate the approach in the context of protein phosphorylation networks, using data simulated from a recent mechanistic model and proteomic data from cancer cell lines. In the former, the true network is known and used for assessment, whereas in the latter, results are compared against known biochemistry. We find that the proposed methodology is more effective at estimating network topology than methods based on linear models.

description: The rapid cycling synchrotron (RCS) of the China Spallation Neutron Source (CSNS) is a high intensity proton ring with beam power of 100 kW. In order to control the residual activation to meet the requirements of hands-on maintenance, a two-stage collimation system has been designed for the RCS. The collimation system consists of one primary collimator made of thin metal to scatter the beam and four secondary collimators as absorbers. Thermal analysis is an important aspect in evaluating the reliability of the collimation system. The calculation of the temperature distribution and thermal stress of the primary collimator with different materials is carried out by using ANSYS code. In order to control the temperature rise and thermal stress of the primary collimator to a reasonable level, an air cooling structure is intended to be used. The mechanical design of the cooling structure is presented, and the cooling effciency with different chin numbers and wind velocity is also analyzed. Finally, the fatigue lifetime of the collimator under thermal shocks is estimated.

description: We prove some new results and unify the proofs of old ones involving complete monotonicity of expressions involving gamma and $q$-gamma functions, $0 < q < 1$. Each of these results implies the infinite divisibility of a related probability measure. In a few cases, we are able to get simple monotonicity without having complete monotonicity. All of the results lead to inequalities for these functions. Many of these were motivated by the bounds in a 1959 paper by Walter Gautschi. We show that some of the bounds can be extended to complex arguments.
