description: Nerve signals in the form of action potentials are relayed between neurons through specialized connections called synapses via neurotransmitter released from synaptic vesicles. The release process is Ca2+ dependent, and relies on fusion of neurotransmitter filled synaptic vesicle with the presynaptic membrane. During high frequency stimulation, the amount of vesicle release increases at some synapses (e.g., frog neuromuscular junction (NMJ)), a process known as short-term plasticity. Due to the micron scale size of the presynaptic active zone where vesicle fusion takes place, experimentally study is often difficult. Thus, computational modeling can provide important insight into the mechanism of synaptic vesicle release at active zones. In the first part of my thesis, I used the frog NMJ as a model synapse for computer simulation studies aimed as testing various mechanistic hypotheses proposed to underlie short-term plasticity. Building off a recently reported excess-bindingsite model of synaptic vesicle release at the frog NMJ (Dittrich et al., 2013), I have investigated several mechanisms of short-term facilitation at the frog NMJ. My studies placed constraints on previously proposed mechanistic models, and concluded that the presence of a second calcium sensor protein on synaptic vesicles distinct from synaptotagmin, can explain known properties of facilitation observed at the frog NMJ. In addition, I was able to identify a second facilitation mechanism, which relied on the persistent binding of calcium bound synaptotagmin molecules to lipids of the presynaptic membrane. In the second part of my thesis, I investigated the structure function relationship at active zones, with the hypothesis that active zones are organized from the same basic synaptic building block consisting of a docked vesicle and a small number of closely associated voltage-gated-calcium-channels (VGCCs). To test this hypothesis, I constructed a vesicle release model of the mouse NMJ by reassembling frog NMJ model building blocks based on electron-microscopy imaging data. These two models successfully predicted the functional divergence between frog and mouse NMJ in terms of average vesicle release and short-term plasticity. In the meanwhile, I found that frog NMJ loses facilitation when VGCCs were systematically removed from active zone. By tracking Ca2+ ions from each individual VGCCs, I further show how the difference in short-term plasticity between frog and mouse NMJ may rise from their distinct release building block assemblies. In summary, I have developed a stochastic computer model of synaptic transmission, which not only shed light on the underlying mechanisms of short-term plasticity, but was also proved powerful in understanding structural and functional relationships at synaptic active zones.

description: We initiate a systematic method to calculate both the finite volume energy levels and form factors from the momentum space finite volume two-point function. By expanding the two point function in the volume we extracted the leading exponential volume correction both to the energy of a moving particle state and to the simplest non-diagonal form factor. The form factor corrections are given in terms of a regularized infinite volume 3-particle form factor and terms related to the Lüsher correction of the momentum quantization. We tested these results against second order Lagrangian and Hamiltonian perturbation theory in the sinh-Gordon theory and we obtained perfect agreement.

description: In this study we elaborate on the recent concept of metagratings proposed in Ra'di et al. [Phys. Rev. Lett. 119, 067404 (2017)] for efficient manipulation of reflected waves. Basically, a metagrating is a set of 1D arrays of polarization line currents which are engineered to cancel scattering in undesirable diffraction orders. We consider a general case of metagratings composed of N polarization electric line currents per supercell. This generalization is a necessary step to totally control diffraction patterns. We show that a metagrating having N equal to the number of plane waves scattered in the far-field can be used for controlling the diffraction pattern. To validate the developed theoretical approach, anomalous and multichannel reflections are demonstrated with 3D full-wave simulations in the microwave regime at 10 GHz. The results can be interesting for the metamaterials community as allow one to significantly decrease the number of used elements and simplify the design of wavefront manipulation devices, what is very convenient for optical and infra-red frequency ranges. Our findings also may serve as a way for development of efficient tunable antennas in the microwave domain.

description: Let $F$ be a self-similar set on $\mathbb{R}$ associated to contractions $f_j(x) = r_j x + b_j$, $j \in \mathcal{A}$, for some finite $\mathcal{A}$, such that $F$ is not a singleton. We prove that if $\log r_i / \log r_j$ is irrational for some $i \neq j$, then $F$ is a set of multiplicity, that is, trigonometric series are not in general unique in the complement of $F$. No separation conditions are assumed on $F$. We establish our result by showing that every self-similar measure $μ$ on $F$ is a Rajchman measure: the Fourier transform $\widehatμ(ξ) \to 0$ as $|ξ| \to \infty$. The rate of $\widehatμ(ξ) \to 0$ is also shown to be logarithmic if $\log r_i / \log r_j$ is diophantine for some $i \neq j$. The proof is based on quantitative renewal theorems for stopping times of random walks on $\mathbb{R}$.

description: We introduce a value-added full-sky catalogue of galaxies, named as Galaxy List for the Advanced Detector Era, or GLADE. The purpose of this catalogue is to (i) help identifications of host candidates for gravitational-wave events, (ii) support target selections for electromagnetic follow-up observations of gravitational-wave candidates, (iii) provide input data on the matter distribution of the local universe for astrophysical or cosmological simulations, and (iv) help identifications of host candidates for poorly localised electromagnetic transients, such as gamma-ray bursts observed with the InterPlanetary Network. Both being potential hosts of astrophysical sources of gravitational waves, GLADE includes inactive and active galaxies as well. GLADE was constructed by cross-matching and combining data from five separate (but not independent) astronomical catalogues: GWGC, 2MPZ, 2MASS XSC, HyperLEDA and SDSS-DR12Q. GLADE is complete up to $d_L = 37^{+3}_{-4}$ Mpc in terms of the cumulative B-band luminosity of galaxies within luminosity distance $d_L$, and contains all of the brightest galaxies giving half of the total B-band luminosity up to $d_L = 91$ Mpc. As B-band luminosity is expected to be a tracer of binary neutron star mergers (currently the prime targets of joint GW+EM detections), our completeness measures can be used as estimations of completeness for containing all binary neutron star merger hosts in the local universe.

description: We assess Gaussian process (GP) regression as a technique to model interatomic forces in metal nanoclusters by analysing the performance of 2-body, 3-body and many-body kernel functions on a set of 19-atom Ni cluster structures. We find that 2-body GP kernels fail to provide faithful force estimates, despite succeeding in bulk Ni systems. However, both 3- and many-body kernels predict forces within a $\sim$0.1 eV/$\textÅ$ average error even for small training datasets, and achieve high accuracy even on out-of-sample, high temperature, structures. While training and testing on the same structure always provides satisfactory accuracy, cross-testing on dissimilar structures leads to higher prediction errors, posing an extrapolation problem. This can be cured using heterogeneous training on databases that contain more than one structure, which results in a good trade-off between versatility and overall accuracy. Starting from a 3-body kernel trained this way, we build an efficient non-parametric 3-body force field that allows accurate prediction of structural properties at finite temperatures, following a newly developed scheme [Glielmo et al. PRB 97, 184307 (2018)]. We use this to assess the thermal stability of Ni$_{19}$ nanoclusters at a fractional cost of full ab initio calculations.

description: An interesting class of models posits that the dark matter is a Majorana fermion which interacts with a quark together with a colored scalar mediator. Such a theory can be tested in direct detection experiments, through dark matter scattering with heavy nuclei, and at the LHC, via jets and missing energy signatures. Motivated by the fact that such theories have spin-independent interactions that vanish at tree level, we examine them at one loop (along with RGE improvement to resum large logs), and find that despite its occurrence at a higher order of perturbation theory, the spin-independent scattering searches typically impose the strongest constraints on the model parameter space. We further analyze the corresponding LHC constraints at one loop and find that it is important to take them into account when interpreting the implications of searches for jets plus missing momentum on this class of models, thus providing the corresponding complementary information for this class of models.

description: Accurately anticipating the toxic risks and specific factors contributing to the toxic risks of nanomaterials is a necessary step for the safe and effective proliferation, utilization, and regulation of these unique materials. This thesis addresses this problem through meta-analysis on existing nanomaterial pulmonary toxicity experiments as enabled by the use of machine learning algorithms including regression trees and random forests models at a time when the completeness of the data do not support traditional meta-analysis techniques like multiple linear regression. This thesis presents the results of analysis using these models to identify the most important nanomaterial characteristics contributing to toxicity as well as the magnitude of changes in toxicity expected from changes in those characteristics. This thesis presents predictive models for the pulmonary toxicity of carbon nanotubes and titanium dioxide nanoparticles showing the degree to which changes in experimental design, nanomaterial dimensions, impurities, and aggregation might explain differences in observed toxicity. Secondly, this thesis presents the predictions of random forest models revealing interactions between 2 or 3 nanomaterial characteristics and exposure attributes in a manner such that a material designer might minimize risk while continuing to meet functional objectives.

description: Using a suite of isolated $L_\star$ galaxy simulations, we show that global depletion times and star-forming gas mass fractions in simulated galaxies exhibit systematic and well-defined trends as a function of the local star formation efficiency per freefall time, $ε_{\rm ff}$, strength of stellar feedback, and star formation threshold. We demonstrate that these trends can be reproduced and explained by a simple physical model of global star formation in galaxies. Our model is based on mass conservation and the idea of gas cycling between star-forming and non-star-forming states on certain characteristic time scales under the influence of dynamical and feedback processes. Both the simulation results and our model predictions exhibit two limiting regimes with rather different dependencies of global galactic properties on the local parameters. When $ε_{\rm ff}$ is small and feedback is inefficient, the total star-forming mass fraction, $f_{\rm sf}$, is independent of $ε_{\rm ff}$ and the global depletion time, $τ_{\rm dep}$, scales inversely with $ε_{\rm ff}$. When $ε_{\rm ff}$ is large or feedback is very efficient, these trends are reversed: $f_{\rm sf} \propto ε_{\rm ff}^{-1}$ and $τ_{\rm dep}$ is independent of $ε_{\rm ff}$ but scales linearly with the feedback strength. We also compare our results with the observed depletion times and mass fractions of star-forming and molecular gas and show that they provide complementary constraints on $ε_{\rm ff}$ and the feedback strength. We show that useful constraints on $ε_{\rm ff}$ can also be obtained using measurements of the depletion time and its scatter on different spatial scales.

No numerical evidence is found for any melting transition, although the correlation length over which vortex crystalline order exists grows as the temperature is reduced. At low temperatures, the relaxation timescales are of an Arrhenius form which can be associated with the creation of dislocations of a size comparable to the correlation length.

Quantifying Strength Size Effects in Polycrystalline Silicon and Aluminum with On-chip Test Platforms
Creators: name: Saleh, Mohamed
Publisher: name: Carnegie Mellon University
Year: 2015
Subjects: subject: Mechanical Engineering
subject: FOS: Mechanical engineering

description: Mechanical strength of components increases as their size decreases. Optimum design of reliable systems at the micro- and nanoscales will account for such size-dependent strength. However, the dependencies of strength on size in brittle ceramic and ductile metal thin films are not well known because of limited data. Therefore, in this thesis, high throughput platforms were designed, fabricated and tested. The strength size effect for polycrystalline silicon (polysilicon) and polycrystalline aluminum thin films has been investigated by on-chip testing techniques. Polysilicon structures over a size range of 100 increase in characteristic strength from 2.7 GPa to 4.2 GPa. A Weibull function alone was insufficient to predict the strength size effect for polysilicon. After taking into account the non-uniform stress distribution in the smallest specimens, both the characteristic strength and the full strength probability distribution function was well predicted. Also, a Monte Carlo technique was developed to predict strength size effects and to assess the minimum number of tests required for accurate characterization of strength distribution. Aluminum thin film structures over a size range of 6.5 increase in average yield strength from 140 MPa to 300 MPa. Unlike macroscale specimens, these samples also exhibit significant scatter in strength. The ratio of the standard deviation in yield strength to the average yield strength is 0.06 for 1 μm thick samples, and more than doubles to 0.13 for 0.6 μm thick samples. High throughput test platforms provide an important method to assess strength and strength distribution data at the micro- and nanoscales.

description: We investigate the tricritical Ising model in complex magnetic field in order to characterize the analytic structure of its free energy. By supplementing analytic methods with the truncation of conformal space technique we obtain nonperturbative data even if the field theories we consider are not integrable. The existence of edge singularities analogous to the Lee-Yang points in the Ising field theory is confirmed. A surprising result, due to the conformal dimensions of the operators involved, is the appearance of two branching points which seems appealing to identify with a pair of complex conjugate spinodal singularities.

description: We incorporate the effects of redshift space distortions and non-linear bias in time-sliced perturbation theory (TSPT). This is done via a new method that allows to map cosmological correlation functions from real to redshift space. This mapping preserves a transparent infrared (IR) structure of the theory and provides us with an efficient tool to study non-linear infrared effects altering the pattern of baryon acoustic oscillations (BAO) in redshift space. We give an accurate description of the BAO by means of a systematic resummation of Feynman diagrams guided by well-defined power counting rules. This establishes IR resummation within TSPT as a robust and complete procedure and provides a consistent theoretical model for the BAO feature in the statistics of biased tracers in redshift space.

In context of the Hamburg Open Science program this repository is going to be extended with a research data repository and supposed to include all researchers, organization units and publications (also non OA, even without any fulltext) building a research information system and a university bibliography. DSpace CRIS is adopting some recommendations for next generation repositories by the Confederation of Open Access Repositories (COAR) and is providing entity structures, which a normal DSpace system does not have yet. Thus we believe, that by sticking with DSpace (CRIS) we are well prepared for the future having a good community with active developers. This presentation shows, how DSpace CRIS helped us to cover the two new components of the repository and which challenges we had to face while developing the new All-in-one system.

description: Waging war against the co-called authority and ruling power of the Western thought, which enslaved the text by one stable and fundamental meaning from the foundations of the Greek civilization until the present time, Jacques Derrida Stages his deliberate endeavor to disturb and shake the whole existence of the Western assumptions and beliefs. He clearly launched his philosophical coup against the governmental legacy of the classical concepts and ideologies at a conference in Johns Hopkins University in 1966 America, where he introduced his intricate ideas and terms through presenting his paper Structure, sign, and System (Bressler 71). No more of the ultimate being that rules and confines the way we perceive a literary work.
In nutshell, Jacques Derrida proposes an alternative approach to textual analysis, which he dubs not a school, or a theory of criticism but simply a „strategic device.‟ It is a kind of lineage steps and techniques that could be applied to a literary text, which contains Western philosophical and conceptual oppositions, in certain sequence, but not necessarily in the same order. Most importantly is to recognize the binary oppositions found in a text; for example, you may encounter the light/dark couple in the text, and, of course, lightness compared to darkness is much more preferable and appeals to our consciousness as something privileged and better than darkness. This hierarchy is inherited from the Western culture as something unassailable and exists outside language.

In all cases the physical parameters of the lepton mixing matrix, three mixing angles and three CP phases can be expressed in terms of a restricted set of independent "theory" parameters that characterize a given choice of CP transformation. This leads to implications for neutrino oscillations as well as neutrinoless double beta decay experiments.

description: We report characterization results for our new silicon photonic chip for high-speed data transmission, called COTTONTAIL (Chip for detector instrumentation with wavelength division multiplex). Modulation bandwidths of different conventional and radiation-hardened travelling-wave Mach-Zehnder modulators are sufficient for very high data transmission rates. Wavelength filters for wavelength division multiplexing show a very low transmission loss of less than 2 dB with a slight wavelength shift of the filtering characteristics. Also included photodiodes are well suited for high speed downlinks in excess of 40 Gbps or on-chip modulator monitoring.

description: This paper over-approximates the reachable sets of a continuous-time uncertain system using the sensitivity of its trajectories with respect to initial conditions and uncertain parameters. We first prove the equivalence between an existing over-approximation result based on the sign-stability of the sensitivity matrices and a discrete-time approach relying on a mixed-monotonicity property. We then present a new over-approximation result which scales at worst linearly with the state dimension and is applicable to any continuous-time system with bounded sensitivity. Finally, we provide a simulation-based approach to estimate these bounds through sampling and falsification. The results are illustrated with numerical examples on traffic networks and satellite orbits.

description: There are many different types of repositories for scientific purposes. Fortunately, more and more institutions and infrastructural units discover the value of digital storages which allow the reuse of research results in the context of open science. Based on this many scientific communities establish a number of commonly used repositories and other publishing platforms for different kinds of scientific output. These platforms and repositories provide only one kind of publication. This causes the problem that it can be difficult to find and to get access to all information about one research project of one scientific group or institution. ZB MED and its publication platform (PUBLISSO) aims not only to establish competitive products for existing best-case-scenarios, but to fill these gaps in publication services. Therefore, PUBLISSO has built a repository which fits all types of publication. PUBLISSO provides access to a broad range of publications (i.e. text publications and research data) at one place. Also, it gives small institutions and communities the opportunity to publish their work at one place. Additionally, PUBLISSO promotes the idea of cross referencing to make relations of publications visible. Therefore, the development of tools of Linked Open Data are constantly monitored and implemented if possible.

description: We study the relationship between (non-)Markovian evolutions, established correlations, and the entropy production rate. We consider a system qubit in contact with a thermal bath and in addition the system is strongly coupled to an ancillary qubit. We examine the steady state properties finding that the coupling leads to effective temperatures emerging in the composite system, and show that this is related to the creation of correlations between the qubits. By establishing the conditions under which the system reaches thermal equilibrium with the bath despite undergoing a non-Markovian evolution, we examine the entropy production rate, showing that its transient negativity is a sufficient sign of non-Markovianity.

description: Given an initial-boundary value problem for an anti-de Sitter-like spacetime, we analyse conditions on the conformal boundary ensuring the existence of Killing vectors in the spacetime arising from this problem. This analysis makes use of a system of conformal wave equations describing the propagation of the Killing equation first considered by Paetz. We identify an obstruction tensor constructed from Killing vector candidate and the Cotton tensor of the conformal boundary whose vanishing is a necessary condition for the existence of Killing vectors in the spacetime. This obstruction tensor vanishes if the conformal boundary is conformally flat.

description: Human travel affects important processes in public health and infectious disease dynamics. Refined spatial and temporal data are needed to accurately model how the dynamics of human travel contribute to epidemiological patterns of disease as well as access to healthcare resources. Here, I address a number of key issues related to modeling human mobility patterns and applications for understanding the spatial spread of infectious diseases and geographic access to public health resources. Using large sources of behavioral data anonymously collected from mobile phones within two African countries, I first analyze the utility of these data to quantify human mobility patterns as well as the usefulness of common modeling frameworks. Then I compare these data to two more common sources of human travel data: the national census and a comprehensive travel survey. Next, I use these data to assess the impact of human travel on the movement of malaria parasites. The final component of my thesis focuses on the utility of this data source to generally understand the role of geographic isolation on travel patterns to better understand the disparity between areas with various levels of access to public resources and the uptake of preventative healthcare such as immunizations and antenatal care.
$QCD_3$ Dualities and the F-Theorem

description: There has recently been a surge of new ideas and results for 2+1 dimensional gauge theories. We consider a recently proposed duality for 2+1 dimensional QCD, which predicts a symmetry-breaking phase. Using the F-theorem, we find bounds on the range of parameters for which the symmetry-breaking phase (and the corresponding duality) can occur. We find exact bounds for an $ SU(2) $ gauge theory, and approximate bounds for an $SU(N) $ gauge theory with $ N>2 $.

description: The preprints landscape has been evolving fast – with a 20-fold increase in the number of preprints posted in the Life Sciences alone, there is no doubt that things are changing. The landscape, however, is very complex, as it involves a wide range of stakeholder groups with somewhat different requirements and objectives. Across 2018 and 2019, Knowledge Exchange and Research Consulting undertook a study on preprints and investigated them through the innovation diffusion theory. Our study has been investigating the core benefits of publication via preprints, attitudes towards them, trends in usage, incentives and disincentives and the core values, strategies, and aims of preprint services providers. We interviewed about 40 stakeholders, including research funders, research performing organisations, service providers (preprint servers) and individual researchers. Based on their views, we were able to fully appreciate the high level of uncertainty in this area, but also its untapped potential. In our proposed presentation, we will provide our views on this increasingly important topic and engage the OR2019 attendees in an open discussion to drive future technical and cultural developments.
The mesoscopic conductance of disordered rings, its random matrix theory, and the generalized variable range hopping picture

description: The calculation of the conductance of disordered rings requires a theory that goes beyond the Kubo-Drude formulation. Assuming "mesoscopic" circumstances the analysis of the electro-driven transitions show similarities with a percolation problem in energy space. We argue that the texture and the sparsity of the perturbation matrix dictate the value of the conductance, and study its dependence on the disorder strength, ranging from the ballistic to the Anderson localization regime. An improved sparse random matrix model is introduced to captures the essential ingredients of the problem, and leads to a generalized variable range hopping picture.

Quantifying and Improving Sales Diversity in Recommender Systems

description: Collaborative filtering approaches have produced some of the most accurate and personalized recommender systems to date by mining for similarities in large-scale datasets. However, despite their stellar performance in accuracy based metrics, researchers have demonstrated a propensity by such algorithms to exaggerate the biases inherent in the data such as popularity or the affinity of users to certain kinds of content. Meanwhile, recommender systems have only grown in importance and have become an integral part of the internet ecosystem, with many users interacting with many recommender systems daily on e-commerce sites, social networks and apps. Therefore, the biases in recommender systems have come to critically impact a company’s bottom line, user satisfaction levels and public image, making it an imperative to develop recommendation diversification methods to explicitly counteract them. In this thesis we make three key contributions to the growing field of sales diversity, which aims to reduce popularity biases inherent in many collaborative filtering based recommender systems. First, we consider the problem of making item-item recommendations, with the goal of redundantly linking from popular items to less popular items in order to bring them more exposure on the web. Next, we consider to the setting of user-item recommendations, and develop a metric we call “discrepancy” to measure the distance between the recommendation distribution desired by a business and the distribution obtained by the recommender system, and develop algorithms to reduce discrepancy while maintaining high recommendation quality. Lastly, we turn our attention to item catalogs and user bases where items and users are clustered into disjoint or overlapping subgroups, and develop metrics to quantify the recommendation diversity experienced both by the users and the items. Our approaches to all three of these problems are unified under a framework of subgraph selection, the use of network flow problems for modeling, and a focus on providing either exact polynomial algorithms or efficient approximation algorithms with concrete performance guarantees. This stands in contrast with existing approaches, most of which are reranking based heuristics for which no performance guarantees can be given. In each of these settings, we augment our theoretical findings with an empirical evaluation on real life datasets from online retailers or standard recommender system datasets provided by Netflix and the MovieLens group, and show that our methods provide superior sales diversity value when compared with competing approaches.
