description: This thesis presents two measurements involving a beauty hadron decaying to a charmonium meson and a strange hadron. First, a measurement of the ratio of branching fractions for Λb→ψ(2S)Λ and Λb→J/ψΛ decays is presented. This analysis uses a data set corresponding to 3 fb-1, collected by the LHCb experiment at a centre-of-mass energy of 7 and 8 TeV. The ratio of branching fractions is determined to be BR(Λb→ψ(2S)Λ)/BR(Λb→J/ψΛ)= 0.513 ± 0.023 (stat) ± 0.016 (syst) ± 0.011 (BR). The second analysis is a on-going measurement of CP violation in g in B0→J/ψKS, B0→ψ(2S)KS and Bs0→J/ψKS decays. The analysed LHCb data sets correspond to 6 fb-1, at a centre-of-mass energy of 13 TeV. The measured sensitivities of the CP parameters S and C in the analysed Bd0 decays are σ(S) = 0.0133 (stat) ± 0.0063 (syst), σ(C) = 0.0125 (stat) ± 0.0042 (syst). This single measurement will have a better sensitivity than the current world average.
description: In dieser Arbeit werden zwei Messungen in Zerfällen von beauty Hadronen in ein charmonium Meson und einem strange Hadron vorgestellt. In der ersten Messung wird das Verhältnis von Verzweigungsverhältnissen von Λb→ψ(2S)Λ und Λb→J/ψΛ Zerfällen bestimmt. Diese Analyse benutzt einen Datensatz der 3 fb-1 entspricht und mit dem LHCb- Experiment bei einer Schwerpunktsenergie von 7 und 8 TeV aufgezeichnet wurde. Das Verhältnis von Verzweigungsverhältnissen ist bestimmt zu BR(Λb→ψ(2S)Λ)/BR(Λb→J/ψΛ)= 0.513 ± 0.023 (stat) ± 0.016 (syst) ± 0.011 (BR). In der zweiten Messung wird CP Verletzung in B0→J/ψKS, B0→ψ(2S)KS und Bs0→J/ψKS Zerfällen bestimmt. Der analysierte LHCb Datensatz entspricht 6 fb-1, aufgenommen bei einer Schwerpunktsenergie von 13 TeV. Die Analyse ist noch nicht abgeschlossen und noch blind. Die gemessenen Präzessionen der CP Parameter S und C in den analysierten Bd0 Zerfällen sind σ(S) = 0.0133 (stat) ± 0.0063 (syst), σ(C) = 0.0125 (stat) ± 0.0042 (syst).

description: Code quality is important when developing software. Therefore, we recommend to teach students practices that improve code quality. An example of such a practice is code refactoring. Mastering this practice is not easy. In practice, the specific knowledge is often acquired from peer experts. The availability of automatic tutoring systems that could help acquiring knowledge in the domain of code refactoring is limited. This study aims at finding an answer how we can automatically generate refactoring guidance based on code context, where the provided code is arbitrary. This study presents a theoretical answer to this question by presenting a model and algorithm. The presented theory is evaluated by a software prototype that takes two concrete models. These models hold knowledge on two refactorings: rename method and extract method as originally described by Fowler. The prototype is used to generate refactoring guidance out of predefined java code in different code contexts. These generated results have been evaluated small-scale with third years undergraduate software engineering students. The models that hold the selected refactorings are limited, but students rate the presented concept and generated results positively.
Disorder and chain superconductivity in YBa_2Cu_3O_{7-δ}

description: The effects of chain disorder on superconductivity in YBa_2Cu_3O_{7-δ} are discussed within the context of a proximity model. Chain disorder causes both pair-breaking and localization. The hybridization of chain and plane wavefunctions reduces the importance of localization, so that the transport anisotropy remains large in the presence of a finite fraction $δ$ of oxygen vacancies. Penetration depth and specific heat measurements probe the pair-breaking effects of chain disorder, and are discussed in detail at the level of the self-consistent T-matrix approximation. Quantitative agreement with these experiments is found when chain disorder is present.

description: Atomic scale engineering of two-dimensional materials could create devices with rich physical and chemical properties. External periodic potentials can enable the manipulation of the electronic band structures of materials. A prototypical system is 3x3-silicene/Ag(111), which has substrate-induced periodic modulations. Recent angle-resolved photoemission spectroscopy measurements revealed six Dirac cone pairs at the Brillouin zone boundary of Ag(111), but their origin remains unclear [Proc. Natl. Acad. Sci. USA 113, 14656 (2016)]. We used linear dichroism angle-resolved photoemission spectroscopy, the tight-binding model, and first-principles calculations to reveal that these Dirac cones mainly derive from the original cones at the K (K') points of free-standing silicene. The Dirac cones of free-standing silicene are split by external periodic potentials that originate from the substrate-overlayer interaction. Our results not only confirm the origin of the Dirac cones in the 3x3-silicene/Ag(111) system, but also provide a powerful route to manipulate the electronic structures of two-dimensional materials.

description: Web archiving is the process of collecting portions of the Web to ensure that the information is preserved for future exploitation. However, despite the increasing number of web archives worldwide, the absence of efficient and meaningful exploration methods still remains a major hurdle in the way of turning them into a usable and useful information source. In this paper, we focus on this problem and propose an RDF/S model and a distributed framework for building semantic profiles ("layers") that describe semantic information about the contents of web archives. A semantic layer allows describing metadata information about the archived documents, annotating them with useful semantic information (like entities, concepts and events), and publishing all this data on the Web as Linked Data. Such structured repositories offer advanced query and integration capabilities, and make web archives directly exploitable by other systems and tools. To demonstrate their query capabilities, we build and query semantic layers for three different types of web archives. An experimental evaluation showed that a semantic layer can answer information needs that existing keyword-based systems are not able to sufficiently satisfy.

description: We calculate numerically the spectrum of disordered electrons in the lowest Landau level at filling factor 1/5 using the self-consistent Hartree-Fock approximation for systems containing up to 400 flux quanta. Special attention is paid to the correct treatment of the q=0 component of the Coulomb interaction. For sufficiently strong disorder, the system is an insulator at this filling factor. We observe numerically a Coulomb gap in the single-particle density of states (DOS). The DOS agrees quantitatively with the predictions for classical point charges.

description: A conjecture on the relation between the cubic Hodge integrals and the topological vertex in topological string theory is resolved. A central role is played by the notion of generalized shift symmetries in a fermionic realization of the two-dimensional quantum torus algebra. These algebraic relations of operators in the fermionic Fock space are used to convert generating functions of the cubic Hodge integrals and the topological vertex to each other. As a byproduct, the generating function of the cubic Hodge integrals at special values of the parameters therein is shown to be a tau function of the generalized KdV (aka Gelfand-Dickey) hierarchies.

description: Low Power Wide Area Networks (LPWANs) are gaining ground in the IoT landscape and, in particular, for Industrial IoT applications. However, given the strict duty cycle restrictions (e.g. 1% in SubGHz bands) and the limited power supply of devices, requirements of some applications can not always be met. This paper analyzes the potential of the combination of packet fragmentation -in the direction of the IETF LPWAN working group- and negative group acknowledgement (NACK) in LoRaWAN networks, a widespread LPWAN technology. Results show that the proposed strategy can lead to significant gains in terms of goodput and energy efficiency under congested situations.

description: A generalized Lyapunov method is outlined which predicts global stability of a broad class of dissipative dynamical systems. The method is applied to the complex Lorenz model and to the Navier-Stokes equations. In both cases one finds compact domains in phase space which contain the omega sets of all trajectories, in particular the fixed points, limit cycles, and strange attractors.

description: Pan-microbial inactivation technologies that do not require high temperatures, reactive chemical compounds, or UV radiation could address gaps in current infection control strategies and provide efficient sterilization of biologics in the biotechnological industry. Here, we demonstrate that femtosecond (fs) laser irradiation of resonant gold nanoparticles (NPs) under conditions that allow for E-field mediated cavitation and shockwave generation achieve an efficient plasmon-enhanced photonic microbial pathogen inactivation. We demonstrate that this NP-enhanced, physical inactivation approach is effective against a diverse group of pathogens, including both enveloped and non-enveloped viruses, and a variety of bacteria and mycoplasma. Photonic inactivation is wavelength-dependent and in the absence of plasmonic enhancement from NPs, negligible levels of microbial inactivation are observed in the near-infrared (NIR) at 800 nm. This changes upon addition of resonant plasmonic NPs, which provide a strong enhancement of inactivation of viral and bacterial contaminants. Importantly, the plasmon-enhanced 800 nm femtosecond (fs)-pulse induced inactivation was selective to pathogens. No measurable damage was observed for antibodies included as representative biologics under identical conditions.

Boson Peak decouples from elasticity in glasses with low connectivity

description: We perform molecular-dynamics simulations of the vibrational and the elasto-plastic properties of polymeric glasses and crystals and corresponding atomic systems. We evidence that the elastic scaling of the density of states in the low-frequency boson peak (BP) region is different in crystals and glasses. Also, we see that the BP of the polymeric glass is nearly coincident with the one of the atomic glasses, thus revealing that the former - differently from elasticity - is controlled by non-bonding interactions only. Our results suggest that the interpretation of the BP in terms of macroscopic elasticity, discussed in highly connected systems, does not hold for systems with low connectivity.

Using femtosecond laser direct writing followed by chemo-mechanical polishing, here we report an ultrahigh quality (Q~10^7) factor lithium niobate (LN) whispering gallery microresonator monolithically integrated with in-plane microelectrodes. Coherent regenerative optomechanical oscillation with an effective mechanical quality (Qm) factor as high as 2.86*10^8 is observed in air. We demonstrate real-time electrical tuning of the optomechanical frequency with an electro-mechanical tuning efficiency around -134 kHz/100V.

description: A solid-on-solid growth model for dimer adsorption and desorption is introduced and studied numerically. The special property of the model is that dimers can only desorb at the edges of terraces. It is shown that the model exhibits a roughening transition from a smooth to a rough phase. In both phases the interface remains pinned to the bottom layer and does not propagate. Close to the transition certain critical properties are related to those of a unidirectionally coupled hierarchy of parity-conserving branching-annihilating random walks.

description: During its orbit around the four million solar mass black hole Sagittarius A* the star S2 experiences significant changes in gravitational potential. We use this change of potential to test one part of the Einstein equivalence principle: the local position invariance (LPI). We study the dependency of different atomic transitions on the gravitational potential to give an upper limit on violations of the LPI. This is done by separately measuring the redshift from hydrogen and helium absorption lines in the stellar spectrum during its closest approach to the black hole. For this measurement we use radial velocity data from 2015 to 2018 and combine it with the gravitational potential at the position of S2, which is calculated from the precisely known orbit of S2 around the black hole. This results in a limit on a violation of the LPI of $|β_{He}-β_{H}| = (2.4 \pm 5.1) \cdot 10^{-2}$. The variation in potential that we probe with this measurement is six magnitudes larger than possible for measurements on Earth, and a factor ten larger than in experiments using white dwarfs. We are therefore testing the LPI in a regime where it has not been tested before.

description: The influence of a modifier based on WC nanoparticles was investigated using bulk Al in a real industrial process using a commercial AlSi hypoeutectic alloy. The modifier was prepared by hot extrusion approach. Its influence was investigated on Al and on commercial Al A356 alloy. The mechanical properties of the Al A356 alloy modified with WC nanoparticles was determined after T6 heat treatment and compared with an unmodified specimen of the same alloy. The results obtained in the modified Al A356 alloy reveal unusual behavior of the mechanical properties, where the elongation of the alloys improved by 32% 64%, while the tensile and the yield strengths remained unchanged. This behavior was attributed to a grain size strengthening mechanism, where strengthening occurs due to the high concentration of grain boundaries, which prevent the dislocations motions in the metal lattice.

description: Electromagnetic plane waves, solutions to Maxwell's equations, are said to be `transverse' in vacuum. Namely, the waves' oscillatory electric and magnetic fields are confined within a plane transverse to the waves' propagation direction. Under tight-focusing conditions however, the field can exhibit longitudinal electric or magnetic components, transverse spin angular momentum, or non-trivial topologies such as Möbius strips. Here, we show that when a suitably spatially structured beam is tightly focused, a 3-dimensional polarization topology in the form of a ribbon with two full twists appears in the focal volume. We study experimentally the stability and dynamics of the observed polarization ribbon by exploring its topological structure for various radii upon focusing and for different propagation planes.

description: Aim: Longitudinal cohort studies are important for understanding the social and health trajectories of people who inject drugs. Little research exists, however, about the motivations, challenges, and experiences of participation in these studies. Methods: To address this gap, we conducted in-depth interviews with participants of an open-ended natural history longitudinal cohort study (SuperMIX) and with fieldworkers who collect the data for this study. Interviews were audio-recorded, and data analyzed thematically. Results: Research findings revealed several motivating factors that encouraged participants to get involved in and stay in the study including financial reimbursement and the opportunity to contribute to a study aiming to improve the lives of peers. Many participants discussed their appreciation of the kindness and respect they were afforded by fieldworkers, and the advocacy role fieldworkers had undertaken with them. While some participants described challenges responding to some questions, there were also expressions of finding the experience therapeutic. Conclusion: Findings provide learnings for future studies and highlight how participation in longitudinal cohort research can provide an opportunity for on-going engagement that affords participants not only a chance to share their experiences, but to contribute to knowledge production and achieve clarity about their own experience.
Remarks on perturbation theory for Hamiltonian systems

description: A comparative discussion of the normal form and action angle variable method is presented in a tutorial way. Normal forms are introduced by Lie series which avoid mixed variable canonical transformations. The main interest is focused on establishing a third integral of motion for the transformed Hamiltonian truncated at finite order of the perturbation parameter. In particular, for the case of the action angle variable scheme, the proper canonical transformations are worked out which reveal the third integral in consistency with the normal form. Details are discussed exemplarily for the Henon-Heiles Hamiltonian. The main conclusions are generalized to the case of n perturbed harmonic oscillators.

description: We report our numerical results for the effect of magnetic anisotropy on a Skyrmion crystal with a high topological number of two, which was recently discovered in an itinerant electron model [R. Ozawa, S. Hayami, and Y. Motome, Phys. Rev. Lett. 118, 147205 (2017)]. By performing numerical simulations based on the kernel polynomial method and the Langevin dynamics for the Kondo lattice model on a triangular lattice, we find that the topological property remains robust against the single-ion anisotropy, while the magnetic texture is deformed continuously. The resultant spin structure is characterized by three wave numbers (triple-$Q$ state), in which the $xy$ component of spins forms a magnetic vortex crystal and the $z$ component of spins behaves a sinusoidal wave. For larger anisotropy, we show that the system exhibits a phase transition from the Skyrmion crystal to topologically trivial phases with vanishing scalar chirality: a single-$Q$ collinear and double-$Q$ noncoplanar states for the easy-axis and easy-plane anisotropy, respectively. We also examine the effect of the single-ion anisotropy in an external magnetic field, and find that the field range of the Skyrmion crystal is rather insensitive to the anisotropy, in contrast to another Skyrmion crystal with the topological number of one whose field range is considerably extended (reduced) by the easy-axis (easy-plane) anisotropy.

description: We show that an electrical shift current is generated when electrons are photoexcited from the valence to conduction bands on a BN nanotube. This photocurrent follows the light pulse envelope and its symmetry is controlled by the atomic structure of the nanotube. We find that the shift current has an intrinsic quantum mechanical signature in which the chiral index of the tube determines the direction of the current along the tube axis. We identify discrete lattice effects in the tangent plane of the tube that lead to an azimuthal component of the shift current. The nanotube shift current can lead to ultrafast opto-electronic and opto-mechanical applications.

Suppression of superconductivity in high-$T_c$ cuprates due to nonmagnetic impurities: Implications for the order parameter symmetry

description: We studied the effects of nonmagnetic impurities on high-temperature superconductors by solving the Bogoliubov-de Gennes equations on a two-dimensional lattice via exact diagonalization technique in a fully self-consistent way. We found that s-wave order parameter is almost unaffected by impurities at low concentrations while $d_{x^2-y^2}$-wave order parameter exhibits a strong linear decrease with impurity concentration. We evaluated the critical impurity concentration $n_i^c$ at which superconductivity ceases to be 0.1 which is in good agreement with experimental values. We also investigated how the orthorhombic nature of the crystal structure affects the suppression of superconductivity and found that anisotropy induces an additional s-wave component. Our results support $d_{x^2-y^2}$-wave symmetry for tetragonal and $s+d_{x^2-y^2}$-wave symmetry for orthorhombic structure.

description: The impact of the maximally possible batch size (for the better runtime) on performance of graphic processing units (GPU) and tensor processing units (TPU) during training and inference phases is investigated. The numerous runs of the selected deep neural network (DNN) were performed on the standard MNIST and Fashion-MNIST datasets. The significant speedup was obtained even for extremely low-scale usage of Google TPUv2 units (8 cores only) in comparison to the quite powerful GPU NVIDIA Tesla K80 card with the speedup up to 10x for training stage (without taking into account the overheads) and speedup up to 2x for prediction stage (with and without taking into account overheads). The precise speedup values depend on the utilization level of TPUv2 units and increase with the increase of the data volume under processing, but for the datasets used in this work (MNIST and Fashion-MNIST with images of sizes 28x28) the speedup was observed for batch sizes >512 images for training phase and >40 000 images for prediction phase. It should be noted that these results were obtained without detriment to the prediction accuracy and loss that were equal for both GPU and TPU runs up to the 3rd significant digit for MNIST dataset, and up to the 2nd significant digit for Fashion-MNIST dataset.

description: There is renewed interest in the question of whether the Navier-Stokes equations (NSE), one of the fundamental models of classical physics and widely used in engineering applications, are actually self-consistent. After recalling the essential physical assumptions inherent in the NSE, the notion of weak solutions, possible implications for the energy conservation law, as well as existence and uniqueness in the incompressible case are discussed. Emphasis will be placed on the possibility of finite time singularities and their consequences for length scales which should be consistent with the continuum hypothesis.

Preserving Both Privacy and Utility in Network Trace Anonymization

description: As network security monitoring grows more sophisticated, there is an increasing need for outsourcing such tasks to third-party analysts. However, organizations are usually reluctant to share their network traces due to privacy concerns over sensitive information, e.g., network and system configuration, which may potentially be exploited for attacks. In cases where data owners are convinced to share their network traces, the data are typically subjected to certain anonymization techniques, e.g., CryptoPAn, which replaces real IP addresses with prefix-preserving pseudonyms. However, most such techniques either are vulnerable to adversaries with prior knowledge about some network flows in the traces, or require heavy data sanitization or perturbation, both of which may result in a significant loss of data utility. In this paper, we aim to preserve both privacy and utility through shifting the trade-off from between privacy and utility to between privacy and computational cost. The key idea is for the analysts to generate and analyze multiple anonymized views of the original network traces; those views are designed to be sufficiently indistinguishable even to adversaries armed with prior knowledge, which preserves the privacy, whereas one of the views will yield true analysis results privately retrieved by the data owner, which preserves the utility. We present the general approach and instantiate it based on CryptoPAn. We formally analyze the privacy of our solution and experimentally evaluate it using real network traces provided by a major ISP. The results show that our approach can significantly reduce the level of information leakage (e.g., less than 1\% of the information leaked by CryptoPAn) with comparable utility.
Temperature dependence of the nematic anchoring energy:mean field analysis

description: In the mean field approximation, we evaluate the temperature dependence of the anchoring energy strength of a nematic liquid crystal in contact with a solid substrate due to thermal fluctuations. Our study is limited to the weak anchoring case, where the microscopic surface energy is small with respect to the mean field energy due to the nematic phase. We assume furthermore that the physical properties of the substrate can be considered temperature independent in the range of the nematic phase. According to the thermodynamical perturbative approach, the macroscopic surface energy is deduced by averaging the microscopic one, with a density matrix containing only the nematic mean field. We show that the thermal renormalization of the anchoring energy coefficients is proportional to the generalized nematic order parameters.

High Performance Computing: Towards Better Performance Predictions and Experiments - Thesis repository

Publisher: name: Zenodo

description: The repository used for writing this manuscript and the slides of Tom Cornebize's PhD defense. Besides the text and images, it also contains the code and a copy of the data used for generating the figures. Abstract: The scientific community relies more and more on computations, notably for numerical simulation and data processing. While many scientific advances were made possible by the technological progress of computers, additional performance gains are still required for larger scale projects. The race for performance is addressed with a growing hardware and software complexity, which in turn increases the performance variability. This can make the experimental study of performance extremely challenging, raising concerns of reproducibility of the experiments, akin to the problems already faced by natural sciences. Our contributions are twofold. First, we present a methodology for predicting the performance of parallel non-trivial applications through simulation. We describe several models for communications and computations, with an increasing complexity. We compare these models through an extensive validation by matching our predictions with real experiments. This validation shows that modeling the spatial and temporal variability of the platform is essential for faithful predictions. As a consequence, predictions require careful sensibility analysis accounting for the uncertainty on the resource models, which we illustrate through several case studies. Second, we present the lessons learned while making the numerous experiments required in the first part and how we improved our methodology. We show that measurements can suffer from multiple experimental biases and we explain how some of these biases can be overcome. We also present how we implemented systematic performance non-regression testing, which allowed us to detect many significant changes of the platform throughout this thesis.
