description: Varroa destructor is an ectoparasitic mite of honeybees which vectors a range of pathogenic viruses, the most notable being Deformed wing virus (DWV). Mites parasitise bees during pupal development and male honeybees, drones, have a longer development cycle than female workers (24 versus 21 days), allow for more progeny mites to develop per foundress (1.6–2.5 compared to 0.7–1.45). How this longer exposure time influences evolution of the transmitted virus population is unknown. Using uniquely tagged viruses recovered from cDNA we investigated the replication, competition and morbidity of DWV genotypes in drones. Assays examining virus replication and morbidity revealed drones are highly susceptible to both predominant genotypes of DWV. In virus passage studies using an equimolar inocula of major DNA genotypes and their recombinants, the recombinant form dominated but did not reach 100% of the virus population within 10 passages. Using an in-silico model of the virus-mite-bee system we examined bottlenecks during virus acquisition by the mite and subsequent injection of viruses into the host, which may play a significant role in shaping virus diversity. This study furthers our understanding of the variables influencing DWV diversity changes and provides insight into areas of future research in the mite/virus/bee system.

description: Using atomistic simulations we investigate the thermodynamical properties of a single atomic layer of hexagonal boron nitride (h-BN). The thermal induced ripples, heat capacity, and thermal lattice expansion of large scale h-BN sheets are determined and compared to those found for graphene (GE) for temperatures up to 1000 K. By analyzing the mean square height fluctuations $< h^2>$ and the height-height correlation function $H(q)$ we found that the h-BN sheet is a less stiff material as compared to graphene. The bending rigidity of h-BN: i) is about 16% smaller than the one of GE at room temperature (300 K), and ii) increases with temperature as in GE. The difference in stiffness between h-BN and GE results in unequal responses to external uniaxial and shear stress and different buckling transitions. In contrast to a GE sheet, the buckling transition of a h-BN sheet depends strongly on the direction of the applied compression. The molar heat capacity, thermal expansion coefficient and the Gruneisen parameter are estimated to be 25.2 J\,mol$^{-1}$\,K$^{-1}$, 7.2$\times10^{-6}$K$^{-1}$ and 0.89, respectively.

description: The dispersive optical model (DOM) as presently implemented can investigate the isospin (nucleon asymmetry) dependence of the Hartree-Fock-like potential relevant for nucleons near the Fermi energy. Data constraints indicate that a Lane-type potential adequately describes its asymmetry dependence. Correlations beyond the mean-field can also be described in this framework, but this requires an extension that treats the non-locality of the Hartree-Fock-like potential properly. The DOM has therefore been extended to properly describe ground-state properties of nuclei as a function of nucleon asymmetry in addition to standard ingredients like elastic nucleon scattering data and level structure. Predictions of nucleon correlations at larger nucleon asymmetries can then be made after data at smaller asymmetries constrain the potentials that represent the nucleon self-energy. A simple extrapolation for Sn isotopes generates predictions for increasing correlations of minority protons with increasing neutron number. Such predictions can be investigated by performing experiments with exotic beams. The predicted neutron properties for the double closed-shell 132Sn nucleus exhibit similar correlations as those in 208Pb. Future relevance of these studies for understanding the properties of all nucleons, including those with high momentum, and the role of three-body forces in nuclei are briefly discussed. Such an implementation will require a proper treatment of the non-locality of the imaginary part of the potentials and a description of high-momentum nucleons as experimentally constrained by the (e,e'p) reactions performed at Jefferson Lab.

description: Solitons are non-dispersive wave solutions that arise in a diverse range of nonlinear systems, stablised by a focussing or defocussing nonlinearity. First observed in shallow water, solitons have subsequently been studied in many other fields including nonlinear optics, biophysics, astrophysics, plasma and particle physics. They are characterised by well localised wavepackets that maintain their initial shape and amplitude for all time, even following collisions with other solitons. Here we report the controlled formation of bright solitary matter-waves, the 3D analog to solitons, from Bose-Einstein condensates of 85Rb and observe their propagation in an optical waveguide. These results pave the way for new experimental studies of bright solitary matterwave dynamics to elucidate the wealth of existing theoretical work and to explore an array of potential applications including novel interferometric devices, the study of short-range atom-surface potentials and the realisation of Schrodingercat states.

Analysis of in vivo purine nucleotide catabolism in Arabidopsis thaliana with focus on nucleoside hydrolase 2

description: Plants can catabolize purine nucleotides to recycle nutrients, in particular nitrogen. The currently established model of purine nucleotide catabolism consists of a branched pathway that starts from AMP and GMP and proceeds either via the intermediates inosine and hypoxanthine or via guanosine and xanthosine to converge on xanthine. Xanthine is further catabolized in a linear fashion by a fully characterized series of reactions to form glyoxylate, carbon dioxide and ammonia. The ammonia released can be re-assimilated into amino acids. This work focuses on how xanthine is generated, in vivo, in Arabidopsis. Metabolite analysis of mutants of a wide set of genes involved in purine catabolism and salvage such as guanosine deaminase, nucleoside hydrolases (NSH), xanthine dehydrogenase, urate oxidase and hypoxanthine guanine phosphoribosyltransferase along with double order and triple order mutants of the same genes showed that xanthine is mainly generated by xanthosine hydrolysis. Inosine and hypoxanthine might enter the pathway from routes other than nucleotide degradation, such as tRNA degradation, DNA repair, and uptake from the soil. Furthermore, xanthosine is not only generated by guanosine deamination as reported in Dahncke and Witte, 2013, but xanthosine monophosphate dephosphorylation is likely to be a source as well. In addition, this work elucidates the function of NSH2. The Arabidopsis genome encodes two nucleoside hydrolases, NSH1 and NSH2. NSH1 is essential for xanthosine and uridine hydrolysis, whereas the function of NSH2 is unclear. Biochemical, genetic and metabolic analyses demonstrate that NSH1 activates NSH2 in vitro and in vivo forming a heterocomplex that has a higher catalytic efficiency for xanthosine, but not for uridine, in comparison to the NSH1 homomer. The heterocomplex formation is also shown for the NSH enzymes of Coffea arabica and Physcomitrella patens, suggesting that this interaction is conserved in the plant kingdom. Dynamic NSH heterocomplex formation might regulate the flux through different branches of nucleotide catabolism. By altering the available amount of NSH2, cell metabolism might be able to upregulate or downregulate the flux through purine degradation, which not only enables the cell to control purine and pyrimidine homeostasis, but might also be useful to deal with certain stress conditions. To summarize, this work unravels how xanthine is generated within the purine nucleotide catabolic pathway of Arabidopsis in vivo, and proposes a revised model in which xanthosine hydrolysis, catalyzed by a heterocomplex of nucleoside hydrolases, serves as the main source of xanthine.

description: We study numerically the crystallization process in a supersaturated suspension of repulsive colloidal particles driven by simple shear flow. The effect of the shear flow on crystallization is two-fold: while it suppresses the initial nucleation, once a large enough critical nucleus has formed its growth is enhanced by the shear flow. Combining both effects implies an optimal strain rate at which the overall crystallization rate has a maximum. To gain insight into the underlying mechanisms, we employ a discrete state model describing the transitions between the local structural configurations around single particles. We observe a time-scale separation between these transitions and the overall progress of the crystallization allowing for an effective Markovian description. By using this model, we demonstrate that the suppression of nucleation is due to the inhibition of a pre-structured liquid.

description: In this work, plant extracts and compounds as a source of biofilm inhibiting substances were analyzed, with a focus on seagrasses and mangroves. To have access to fresh plant material, and to limit plant collection in the wild, mangrove cultivation in the greenhouse was studied. Good growth and successful propagation of Avicennia germinans and Laguncularia racemosa was achieved. Bruguiera cylindrica was growing very slowly and could not be propagated. The composition of secondary metabolites present in greenhouse grown A. germinans was comparable to plants collected outdoors in Guatemala. The internal transcribed spacer (ITS) as a genetic marker was shown to be a useful tool in the clear species identification of mangroves. Different microbial biofilm assays were carried out to study biofilm inhibitory actions of plant extracts. In a biofilm assay specific for Escherichia coli macrocolony growth and extracellular polymeric substance (EPS) production, different tea varieties and one flavonoid were screened in a first approach. Green tea and hawthorn tea as well as the flavonoid taxifolin showed good inhibitory activities. Three seagrass species, namely Enhalus acoroides, Halophila ovalis and Halodule pinifolia were tested in different biofilm assays on E. coli and Candida albicans. E. acoroides showed to be a promising source of biofilm inhibiting compounds, which are also able to induce cell dispersion from C. albicans biofilms. In preliminary experiments with mangrove extracts on biofilm inhibition, extracts of L. racemosa were most effective. Crude extracts of L. racemosa were able to reduce biofilm formation of E. coli, C. albicans and Candida glabrata in microtiter-based assays. To identify the active compounds, fractions of the crude extract enriched for phenolic compounds were tested. Here, two fractions inhibited C. albicans biofilm adhesion to 51 and 57%, respectively, compared to the positive control. The substances in the fractions were identified as ellagitannins and one gallotannin by liquid chromatography-mass spectrometry (LC-MS) and nuclear magnetic resonance (NMR) spectroscopy. Obtained mass-spectrometric fragmentation patterns were compared to databases and the literature. According to this study, mangroves and seagrasses can be considered as a source of biofilm inhibiting compounds.

description: We investigate the low temperature structural and electronic properties of the type-I clathrate Eu8Ga16Ge30 under pressure using x-ray powder diffraction (XRD), x-ray absorption near-edge structure (XANES) and x-ray magnetic circular dichroism (XMCD) techniques. The XRD measurements reveal a transition to an amorphous phase above 18 GPa. Unlike previous reports on other clathrate compounds, no volume-collapse is observed prior to the crystalline-amorphous phase transition which takes place when the unit cell volume is reduced to 81% of its ambient pressure value. Fits of the pressure-dependent relative volume to a Murnaghan equation of state (EOS) yield a bulk modulus B0 = 65+-3 GPa and a pressure derivative B'0 = 3.3+-0.5. The Eu L2-edge XMCD data shows quenching of the magnetic order at the crystalline-amorphous phase transition. The XANES spectra indicate the persistence of Eu2+ valency state up to 22 GPa, therefore the suppression of XMCD intensity is due to the loss of magnetic order as a result of frustrated exchange interactions in the amorphous phase, and not due to quenching of local moments. When compared with other clathrates, the results point to the importance of guest ion-cage interactions in determining the mechanical stability of the framework structure and the critical pressure for amorphization. Finally, the crystalline structure is not found to recover after pressure release, resulting in a novel amorphous material that is at least metastable at ambient pressure and temperature.

description: Significant efforts have gone into the development of statistical models for analyzing data in the form of networks, such as social networks. Most existing work has focused on modeling static networks, which represent either a single time snapshot or an aggregate view over time. There has been recent interest in statistical modeling of dynamic networks, which are observed at multiple points in time and offer a richer representation of many complex phenomena. In this paper, we propose a state-space model for dynamic networks that extends the well-known stochastic blockmodel for static networks to the dynamic setting. We then propose a procedure to fit the model using a modification of the extended Kalman filter augmented with a local search. We apply the procedure to analyze a dynamic social network of email communication.

description: The volatility of financial instruments is rarely constant, and usually varies over time. This creates a phenomenon called volatility clustering, where large price movements on one day are followed by similarly large movements on successive days, creating temporal clusters. The GARCH model, which treats volatility as a drift process, is commonly used to capture this behavior. However research suggests that volatility is often better described by a structural break model, where the volatility undergoes abrupt jumps in addition to drift. Most efforts to integrate these jumps into the GARCH methodology have resulted in models which are either very computationally demanding, or which make problematic assumptions about the distribution of the instruments, often assuming that they are Gaussian. We present a new approach which uses ideas from nonparametric statistics to identify structural break points without making such distributional assumptions, and then models drift separately within each identified regime. Using our method, we investigate the volatility of several major stock indexes, and find that our approach can potentially give an improved fit compared to more commonly used techniques.

description: The relativistic heavy ion collider (RHIC) was constructed to achieve an asymptotic state of nuclear matter in heavy ion collisions, a near-ideal gas of deconfined quarks and gluons denoted quark-gluon plasma or QGP. RHIC collisions are indeed very different from the hadronic processes observed at the Bevalac and AGS, but high-energy elementary-collision mechanisms are also non-hadronic. The two-component model (TCM) combines measured properties of elementary collisions with the Glauber eikonal model to provide an alternative asymptotic limit for A-A collisions. RHIC data have been interpreted to indicate formation of a {\em strongly-coupled} QGP or "perfect liquid". In this review I consider the experimental evidence that seems to support such conclusions and alternative evidence that may conflict with those conclusions and suggest different interpretations.

description: Thermodynamical stability of fluid spheres is studied in the presence of a cosmological constant, both in the Newtonian limit, as well as in General Relativity. In all cases, an increase of the cosmological constant tends to stabilize the system, making asymptotically de Sitter space more thermodynamically stable than anti-de Sitter at the purely classical level. In addition, in the Newtonian case reentrant phase transitions are observed for a positive cosmological constant, due to its repelling property in this case. In General Relativity is studied the case of radiation, for which is found that the critical radius, at which an instability sets in, is always bigger than the black hole radius of the system and furthermore, at some value of the cosmological constant this critical radius hits at the cosmological horizon.

description: We consider stationary extreme black hole solutions to the Einstein-Yang-Mills equations in four dimensions, allowing for a negative cosmological constant. We prove that any axisymmetric black hole of this kind possesses a near-horizon AdS(2) symmetry and deduce its near-horizon geometry must be that of the abelian embedded extreme Kerr-Newman (AdS) black hole. We also show that the near-horizon geometry of any static black hole is a direct product of AdS(2) and a constant curvature space.

description: Classifying streaming data requires the development of methods which are computationally efficient and able to cope with changes in the underlying distribution of the stream, a phenomenon known in the literature as concept drift. We propose a new method for detecting concept drift which uses an Exponentially Weighted Moving Average (EWMA) chart to monitor the misclassification rate of an streaming classifier. Our approach is modular and can hence be run in parallel with any underlying classifier to provide an additional layer of concept drift detection. Moreover our method is computationally efficient with overhead O(1) and works in a fully online manner with no need to store data points in memory. Unlike many existing approaches to concept drift detection, our method allows the rate of false positive detections to be controlled and kept constant over time.

description: Aiming at the investigation of above-threshold ionization in super-strong laser fields with highly charged ions, we develop a Coulomb-corrected strong field approximation (SFA). The influence of the Coulomb potential of the atomic core on the ionized electron dynamics in the continuum is taken into account via the eikonal approximation, treating the Coulomb potential perturbatively in the phase of the quasi-classical wave function of the continuum electron. In this paper the formalism of the Coulomb-corrected SFA for the nonrelativistic regime is discussed employing velocity and length gauge. Direct ionization of a hydrogen-like system in a strong linearly polarized laser field is considered. The relation of the results in the different gauges to the Perelomov-Popov-Terent'ev imaginary-time method is discussed.

description: It is well known that the reproductive performance of boars has always been regarded as an important factor influencing the population reproduction, and semen quality is the key factor determining the boar fertility, and semen is produced a combination of the testis, epididymis, prostate gland, vesicular gland, and bulbourethral gland. However, previous studies on the reproductivity of BMI boars mainly focused on the testes, with little attention on the epididymis, prostate gland, vesicular gland, and bulbourethral gland.

description: We present temperature dependent magnetic neutron diffraction measurements on Ba(Fe$_{1-x}$Co$_{x}$)$_{2}$As$_{2}$ for $x$ = 0.039, 0.022, and 0.021 as-grown single crystals. Our investigations probe the behavior near the magnetic tricritical point in the ($x$,$T$) plane, $x_{tr} \approx $0.022, as well as systematically exploring the character of the magnetic phase transition across a range of doping values. All samples show long range antiferromagnetic order that may be described near the transition by simple power laws, with $β$ =~0.306$\pm$0.060 for $x$ =~0.039, $β$ =~0.208$\pm$0.005 for $x$ =~0.022, and $β$ =~0.198$\pm$0.009 for $x$ =~0.021. For the $x$ =~0.039 sample, the data are reasonably well described by the order parameter exponent $β$ =~0.326 expected for a 3D Ising model while the $x$ =~0.022 and $x$ =~0.021 samples are near the $β$ =~0.25 value for a tricritical system in the mean-field approximation. These results are discussed in the context of existing experimental work and theoretical predictions.

description: High stress stoichiometric silicon nitride resonators, whose quality factors exceed one million, have shown promise for applications in sensing and signal processing. Yet, electrical integration of the insulating silicon nitride resonators has been challenging, as depositing even a thin layer of metal degrades the quality factor significantly. In this work, we show that graphene used as a conductive coating for Si3N4 membranes reduces the quality factor by less than 30 % on average, which is minimal when compared to the effect of conventional metallization layers such as chromium or aluminum. The electrical integration of Si3N4-Graphene (SiNG) heterostructure resonators is demonstrated with electrical readout and electro-static tuning of the frequency by up to 1 % per volt. These studies demonstrate the feasibility of hybrid graphene/nitride mechanical resonators in which the electrical properties of graphene are combined with the superior mechanical performance of silicon nitride.
