description: A study is made of frequency comb generation described by the driven and damped nonlinear Schrödinger equation on a finite interval. It is shown that frequency comb generation can be interpreted as a modulational instability of the continuous wave pump mode, and a linear stability analysis, taking into account the cavity boundary conditions, is performed. Further, a truncated three-wave model is derived, which allows one to gain additional insight into the dynamical behaviour of the comb generation. This formalism describes the pump mode and the most unstable sideband and is found to connect the coupled mode theory with the conventional theory of modulational instability. An in-depth analysis is done of the nonlinear three-wave model. It is demonstrated that stable frequency comb states can be interpreted as attractive fixed points of a dynamical system. The possibility of soft and hard excitation states in both the normal and the anomalous dispersion regime is discussed. Investigations are made of bistable comb states, and the dependence of the final state on the way the comb has been generated. The analytical predictions are verified by means of direct comparison with numerical simulations of the full equation and the agreement is discussed.

description: In eukaryotes, genetic material is stored as chromatin, a DNA-protein complex whose structure is tightly regulated. Histones are the main protein components of chromatin and their post-translational modifications (PTMs) influence several cellular processes, from gene expression to epigenetic regulation and inheritance. Histone acetyltransferases carry out the acetylation of histones, an abundant modification, the function of which is determined by the position of the modified residue. Histone chaperones can influence the specificity of the histone acetyltransferases, however, the underlying mechanism of this process is not fully understood. Rtt109 is a fungal histone acetyltransferase which is essential for the acetylation of newly synthesized histone H3. Two distinct histone chaperones, Asf1 and Vps75, have been reported to alter its activity and specificity: while Asf1 is necessary for H3 K56 acetylation, Vps75 promotes acetylation of H3 K9, K23 and K27, which are located in a long disordered N-terminal tail of H3. Despite the availability of structures of Rtt109 in complex with Vps75, the mechanism of regulation of Rtt109 activity by Asf1 and Vps75 remains elusive. In order to understand how Asf1 and Vps75 stimulate the Rtt109 activity towards specific substrates, I reconstituted in vitro the complex containing Rtt109, histones H3:H4 and both chaperones. With multi angle light scattering and nuclear magnetic resonance (NMR), I could show that the Vps75 dimer assembles a non-symmetric complex with one copy of Rtt109 and Asf1-bound histones. Using an integrative structural biology approach combining distance restraint information from NMR and low-resolution shape information from small-angle neutron scattering (SANS) data, I could obtain a structural model of this complex. The structure revealed that the chaperones form a bagel-shaped complex with Rtt109 and the histones, bringing the enzyme and the substrate together and positioning H3 K56 next to the Rtt109 active center. A combination of NMR data with biochemical experiments and computational studies, revealed that the flexible H3 tail is chaperoned by Asf1 and is guided towards the catalytic pocket of Rtt109 by both folded and unfolded structural elements of Vps75. These results, taken together with existing literature and further mutational studies, allowed me to propose a mechanism by which the histone chaperones promote acetylation of the disordered H3 N-terminal tail.

description: We report on the polarization measure, obtained with IBIS on board INTEGRAL, of the prompt emission of GRB 061122. Over an 8 s interval containing the brightest part of the Gamma-Ray Burst we put a lower limit on its polarization fraction of 60% at 68% c.l. and of 33% at 90% c.l. on the 250-800 keV energy range. We performed late time optical and near infra-red imaging observations of the GRB field using the Telescopio Nazionale Galileo (TNG), and the Canada-France-Hawaii Telescope (CFHT). Our multi-band (ugrizYJHK) photometry allowed us to identify the host galaxy of GRB 061122 and to build its SED. Using a photometric redshift code we fitted these data, and derived the basic properties of the galaxy, including its type and redshift, that we could constrain to the interval [0.57, 2.10] at a 90% c.l., with a best fit value of z=1.33. The polarization measurement in different energy bands, together with the distance determination, allowed us to put the most stringent limit (xi < 3.4x10-16) to date to a possible Lorentz Invariance Violation based on the vacuum birefringence effect, predicted by some quantum-gravity theories.

description: We study static, spherically symmetric, self-gravitating systems minimally coupled to a scalar field with U(1) gauge symmetry: charged boson stars. We find numerical solutions to the EinsteinMaxwell equations coupled to the relativistic Klein-Gordon equation. It is shown that bound stable configurations exist only for values of the coupling constant less than or equal to a certain critical value. The metric coefficients and the relevant physical quantities such as the total mass and charge, turn out to be in general bound functions of the radial coordinate, reaching their maximum values at a critical value of the scalar field at the origin. We discuss the stability problem both from the quantitative and qualitative point of view. Taking properly into account the electromagnetic contribution to the total mass, the stability issue is faced also following an indication of the binding energy per particle, verifying then the existence of configurations having positive binding energy: objects apparently bound can be unstable against small perturbations, in full analogy with what observed in the mass-radius relation of neutron stars.

description: Das Projekt LIVO will mit seinen autarken Tiny Houses Abhilfe gegen städtische Wohnungs-not und Umweltverschmutzung schaffen. Bevor die ersten Häuser realisiert werden, gilt es zu prüfen, ob das aktuelle Konzept die Wohnbedürfnisse der Generation Y erfüllt und wie sich potenzielle LIVO Bewohnende charakterisieren lassen. Um diese Ziele zu erreichen, werden mit einem quantitativen Fragebogen (n = 89) die Wohnbedürfnisse der Generation Y und deren Bewertung des LIVO Konzepts festgestellt, um daraus Produktanpassungen ab-zuleiten. Um ein klares Bild der potenziellen LIVO Bewohnenden zu erhalten, werden mit Personen, die sich vorstellen können in einem LIVO Haus zu wohnen, qualitative Leitfaden-Interviews (n = 4) durchgeführt und die Resultate in Personas zusammengefasst. Die Ergebnisse der Arbeit zeigen, dass Personen aus der Generation Y sehr heterogene Wohnbedürfnisse aufweisen. Die Befragten stimmen bei ihren Wohnbedürfnissen aber da-hingehend überein, dass Wohnraum als Rückzugsort insbesondere Privatsphäre und Schutz vor der Aussenwelt bieten soll. Weitere wichtige Kriterien von Wohnraum stellen für die Generation Y die Helligkeit, die Lage, die Kosten, die Gestaltungsmöglichkeiten, das Ermöglichen von sozialer Interaktion, Platz zum Arbeiten und ein privater Aussenbereich dar. Neben baulichen Anpassungen am Konzept wird insbesondere empfohlen, das Projekt LIVO als Mietenden-Genossenschaft an einem fixen Standort zu denken. Mit Gemeinschaftsräumen sollen soziale Begegnungen und das Teilen von Wohnraum sowie materiellen Gütern ermöglicht werden. Damit wird sichergestellt, dass LIVO die Wohnbedürfnisse seiner zukünftigen Bewohnenden, welche sich durch die Werte Universalismus und Selbststeuerung sowie ihrem Wunsch nach Minimalismus, Gemeinwohl und engen Nachbarschaftsbeziehungen charakterisieren lassen, erfüllt.

description: Large scale analysis and statistics of socio-technical systems that just a few short years ago would have required the use of consistent economic and human resources can nowadays be conveniently performed by mining the enormous amount of digital data produced by human activities. Although a characterization of several aspects of our societies is emerging from the data revolution, a number of questions concerning the reliability and the biases inherent to the big data "proxies" of social life are still open. Here, we survey worldwide linguistic indicators and trends through the analysis of a large-scale dataset of microblogging posts. We show that available data allow for the study of language geography at scales ranging from country-level aggregation to specific city neighborhoods. The high resolution and coverage of the data allows us to investigate different indicators such as the linguistic homogeneity of different countries, the touristic seasonal patterns within countries and the geographical distribution of different languages in multilingual regions. This work highlights the potential of geolocalized studies of open data sources to improve current analysis and develop indicators for major social phenomena in specific communities.

description: During the beam commissioning of the Large Hadron Collider (LHC) with 150, 75, 50 and 25-ns bunch spacing, important electron-cloud effects, like pressure rise, cryogenic heat load, beam instabilities or emittance growth, were observed. A method has been developed to infer different key beam-pipe surface parameters by benchmarking simulations and pressure rise observed in the machine. This method allows us to monitor the scrubbing process (i.e. the reduction of the secondary emission yield as a function of time) in the regions where the vacuum-pressure gauges are located, in order to decide on the most appropriate strategies for machine operation. In this paper we present the methodology and first results from applying this technique to the LHC.

description: Proxy servers are being increasingly deployed at organizations for performance benefits; however, there still exists drawbacks in ease of client authentication in interception proxy mode mainly for Open Source Proxy Servers. Technically, an interception mode is not designed for client authentication, but implementation in certain organizations does require this feature. In this paper, we focus on the World Wide Web, highlight the existing transparent proxy authentication mechanisms, its drawbacks and propose an authentication scheme for transparent proxy users by using external scripts based on the clients Internet Protocol Address. This authentication mechanism has been implemented and verified on Squid-one of the most widely used HTTP Open Source Proxy Server.

description: An important question in molecular evolution is whether an amino acid that occurs at a given position makes an independent contribution to fitness, or whether its effect depends on the state of other loci in the organism's genome, a phenomenon known as epistasis. In a recent letter to Nature, Breen et al. (2012) argued that epistasis must be "pervasive throughout protein evolution" because the observed ratio between the per-site rates of non-synonymous and synonymous substitutions (dN/dS) is much lower than would be expected in the absence of epistasis. However, when calculating the expected dN/dS ratio in the absence of epistasis, Breen et al. assumed that all amino acids observed in a protein alignment at any particular position have equal fitness. Here, we relax this unrealistic assumption and show that any dN/dS value can in principle be achieved at a site, without epistasis. Furthermore, for all nuclear and chloroplast genes in the Breen et al. dataset, we show that the observed dN/dS values and the observed patterns of amino acid diversity at each site are jointly consistent with a non-epistatic model of protein evolution.

description: This work devises a formalism to obtain the equations of motion for a black hole-fluid configuration. Our approach is based on a Post-Newtonian expansion and adapted to scenarios where obtaining the relevant dynamics requires long time-scale evolutions. These systems are typically studied with Newtonian approaches, which have the advantage that larger time-steps can be employed than in full general-relativistic simulations, but have the downside that important physical effects are not accounted for. The formalism presented here provides a relatively straightforward way to incorporate those effects in existing implementations, up to 2.5PN order, with lower computational costs than fully relativistic simulations.

description: In supersymmetric models, a correlation exists between the structure of the Higgs sector quartic potential and the coupling of the lightest CP-even Higgs to fermions and gauge bosons. We exploit this connection to relate the observed value of the Higgs mass ~ 125 GeV to the magnitude of its couplings. We analyze different scenarios ranging from the MSSM with heavy stops to more natural models with additional non-decoupling D-term/F-term contributions. A comparison with the most recent LHC data, allows to extract bounds on the heavy Higgs boson masses, competitive with bounds from direct searches.

description: The spectrum of Lyapunov exponents is powerful tool for the analysis of the complex system dynamics. In the general framework of nonlinear dynamical systems a number of the numerical technics have been developed to obtain the spectrum of Lyapunov exponents for the complex temporal behavior of the systems with a few degree of freedom. Unfortunately, these methods can not apply directly to analysis of complex spatio-temporal dynamics in plasma devices which are characterized by the infinite phase space, since they are the spatially extended active media. In the present paper we propose the method for the calculation of the spectrum of the spatial Lyapunov exponents (SLEs) for the spatially extended beam-plasma systems. The calculation technique is applied to the analysis of chaotic spatio-temporal oscillations in three different beam-plasma model: (1) simple plasma Pierce diode, (2) coupled Pierce diodes, and (3) electron-wave system with backward electromagnetic wave. We find an excellent agreement between the system dynamics and the behavior of the spectrum of the spatial Lyapunov exponents. Along with the proposed method, the possible problems of SLEs calculation are also discussed. It is shown that for the wide class of the spatially extended systems the set of quantities included in the system state for SLEs calculation can be reduced using the appropriate feature of the plasma systems.

Electron energy loss spectroscopy: an analytical technique for the investigation of optical and chemical properties in 2D materials and in-situ TEM holders

description: This PhD originally started under the title “Plasmon Tailoring of 2D Transition Metal Dichalcogenides Studied via Electron Energy Loss Spectroscopy”. The intended research goal was to investigate the plasmon properties of two-dimensional (2D) transition metal dichalcogenide (TMDC) semiconductors with electron energy loss spectroscopy (EELS) and then modify the material to change these properties in a controlled way. Throughout the course of the PhD research, this goal shifted to focus more on the technique of EELS and less on 2D materials.An investigation into the plasmonic properties of pristine (unmodified) MoS2 lead to the publication of a first-author journal article in the Journal of Microscopy [1]. After this publication, the intent was to investigate different techniques for modifying MoS2 and other 2D TMDCs. The first approach was to investigate the effects of low energy ion implantation in creating substitutional implants in 2D MoS2 and MoSe2. Unfortunately, due to instrumental issues, sample cleanliness issues, and the effects of the Covid19 pandemic, this route did not produce any meaningful results towards this thesis. Contributions were made however to the PhD thesis of fellow student Dr. Michael Hennessy [2] and his publication in the journal Microscopy and Microanalysis [3]. The next avenue of investigation was rather than modifying the plasmons within the 2D TMDC itself, plasmonic metal nanostructures were placed on top of excitonic 2D TMDC substrates to study the coupling of excitons and plasmons. Again, the same struggles as before lead to a lack of meaningful results to contribute towards this thesis. During this time however, I was able to design and oversee the Final Year Project and MSc. Thesis of students, Neil Mulcahy and Liam Cregg respectively, on the topic of using the MNPBEM [4] simulation package to model optical and EEL spectra of metal nanostructures. These endeavours may not have contributed directly to this thesis but regardless, they were invaluable learning experiences in collaborative science and supervision of projects, while also developing skills related to electron microscopy and spectroscopy. Finally, a side project using EELS to study materials inside of an in-situ TEM holder, evolved to become a substantial investigation into the practical application of in-situ EELS, with a major focus on open access to data and open-source analysis tools.

description: (Abridged) Star and planet formation theories predict an evolution in the density, temperature, and velocity structure as the envelope collapses and forms an accretion disk. The aim of this work is to model the evolution of the molecular excitation, line profiles, and related observables during low-mass star formation. Specifically, the signatures of disks during the deeply embedded stage are investigated. Semi-analytic 2D axisymmetric models have been used to describe the evolution of the density, stellar mass, and luminosity from the pre-stellar to the T-Tauri phase. A full radiative transfer calculation is carried out to accurately determine the time-dependent dust temperatures and CO abundance structure. We present non-LTE near-IR, FIR, and submm lines of CO have been simulated at a number of time steps. In contrast to the dust temperature, the CO excitation temperature derived from submm/FIR lines does not vary during the protostellar evolution, consistent with C18O observations obtained with Herschel and from ground-based telescopes. The near-IR spectra provide complementary information to the submm lines by probing not only the cold outer envelope but also the warm inner region. The near-IR high-J (>8) absorption lines are particularly sensitive to the physical structure of the inner few AU, which does show evolution. High signal-to-noise ratio subarcsec resolution data with ALMA are needed to detect the presence of small rotationally supported disks during the Stage 0 phase and various diagnostics are discussed.

description: We apply a tree-based methodology to solve new, very broadly defined families of nested recursions of the general form R(n)=sum_{i=1}^k R(n-a_i-sum_{j=1}^p R(n-b_{ij})), where a_i are integers, b_{ij} are natural numbers, and k,p are natural numbers that we use to denote "arity" and "order," respectively, and with some specified initial conditions. The key idea of the tree-based solution method is to associate such recursions with infinite labelled trees in a natural way so that the solution to the recursions solves a counting question relating to the corresponding trees. We characterize certain recursion families within R(n) by introducing "simultaneous parameters" that appear both within the recursion itself and that also specify structural properties of the corresponding tree. First, we extend and unify recently discovered results concerning two families of arity k=2, order p=1 recursions. Next, we investigate the solution of nested recursion families by taking linear combinations of solution sequence frequencies for simpler nested recursions, which correspond to superpositions of the associated trees; this leads us to identify and solve two new recursion families for arity k=2 and general order p. Finally, we extend these results to general arity k>2. We conclude with several related open problems.

description: The proposed experiment aims to expand existing research by examining the influence of personality traits and social support on hair-pulling severity in individuals with Trichotillomania (TTM). The primary objectives are twofold: firstly, we aim to validate previous findings regarding the association between the Big Five personality traits and hair-pulling severity in TTM patients, particularly around the predictive role of Neuroticism. Secondly, to explore the potential mediating effect of social support on the relationship between personality traits and hair-pulling severity in TTM patients. Data collection will be survey-based, anonymous and run online using a secure survey platform. The survey will assess the Big Five personality traits, social support, stress levels, life satisfaction, and hair-pulling severity.

The Formation and Dynamics of Super-Earth Planets

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Super-Earths, objects slightly larger than Earth and slightly smaller than Uranus, have found a special place in exoplanetary science. As a new class of planetary bodies, these objects have challenged models of planet formation at both ends of the spectrum and have triggered a great deal of research on the composition and interior dynamics of rocky planets in connection to their masses and radii. Being relatively easier to detect than an Earth-sized planet at 1 AU around a G star, super-Earths have become the focus of worldwide observational campaigns to search for habitable planets. With a range of masses that allows these objects to retain moderate atmospheres and perhaps even plate tectonics, super-Earths may be habitable if they maintain long-term orbits in the habitable zones of their host stars. Given that in the past two years a few such potentially habitable super-Earths have in fact been discovered, it is necessary to develop a deep understanding of the formation and dynamical evolution of these objects. This article reviews the current state of research on the formation of super-Earths and discusses different models of their formation and dynamical evolution.

description: The magnetism of Sr$_2$F$_2$Fe$_2$OS$_2$ was examined through neutron powder diffraction and thermodynamic and transport measurements. Quasi-two-dimensional magnetic order develops below $T_N$ = 106(2) K with an in-plane correlation length exceeding 310 Å and an out-of-plane correlation length of just 17(3) Å. The data are consistent with a two-k structure with $k_1$ = (1/2, 0, 1/2) and $k_2$ = (0, 1/2, 1/2) and an ordered moment of 3.3(1) $μ_B$ oriented along the in-plane components of k. This structure is composed of orthogonal AFM chains intersecting at super-exchange mediating O sites. Density Functional Theory (DFT) also points to this structure and a narrower Fe 3d band than for the iron pnictides from which electronic correlations produce a Mott insulator.

description: Hydrogen is a promising alternative energy carrier that can potentially facilitate the transition from fossil fuels to sources of clean energy because of its prominent advantages such as high energy density (142 MJ per kg), great variety of potential sources (for example water, biomass, organic matter), and low environmental impact (water is the sole combustion product). However, due to its light weight, the efficient storage of hydrogen is still an issue investigated intensely. Various solid media have been considered in that respect among which magnesium hydride stands out as a candidate offering distinct advantages. Recent theoretical work indicates that MgH2 becomes less thermodynamically stable as particle diameter decreases below 2 nm. Our DFT (density functional theory) modeling studies have shown that the smallest enthalpy change, corresponding to 2 unit-cell thickness (1.6 Å Mg/3.0Å MgH2) of the film, is 57.7 kJ/molMg. This enthalpy change is over 10 kJ per molMg smaller than that of the bulk. It is important to note that the range of enthalpy change for systems that are suitable for mobile storage applications is 15 to 24 kJ permolH at 298 K. The important key for the development of air/stable Mg/nanocrystals is the use of PMMA (polymethylmethacrylate) as an encapsulation agent. In our work we use laser ablation, a non-electrochemical method, for producing well dispersed nanoparticles without the presence of any long range aggregation. The observed improved hydrogenation characteristics of the polymer/stable Mg-nanoparticles are associated to the preparation procedure and in any case the polymer laser ablation is a new approach for the production of air/protected and inexpensive Mg/nanoparticles.

GOCE gradients in various reference frames and their accuracies

description: The objective of GOCE (Gravity Field and Steady-State Ocean Circulation Explorer) is the determination of the Earth's gravity field with high spatial resolution. The main science sensor (the gradiometer) measures differential accelerations, from which the gravitational gradients, i.e. the matrix of the second derivatives of the gravitational potential, are derived. Some of them (the diagonal components of the gravitational tensor) are observed with highest accuracy, 4 mE/?Hz in a frequency range from 5 mHz to 100 mHz, whereas the off-diagonals are obtained less accurately. The gradients will be observed in the instrument frame, which approximates the along-track oriented, local orbital frame. For the transformation of the gradients in other frames (e.g. in the strictly earth-pointing frame or a local geodetic frame), the transformation parameters (orientation angles) and all components of the gravity tensor have to be known with sufficient accuracy. We show how the elements of the gravitational tensor and their accuracies look like in the various frames as well as their spectral behaviour, if only the GOCE observations are used for the transformation. Only V zz' keeps approximately its original accuracy in all frames discussed, except in the earth-fixed frame ITRF (International Terrestrial Reference Frame). Therefore we recommend to analyse the gradients as 'close' as possible in the observation frame.
