Recent Progress and Emerging Trends in Molecular Dynamics

description: Abstract: The methodology to simulate transport phenomena in bulk systems is well-established. In contrast, there is no clear consensus about the choice of techniques to model cross-transport phenomena and phoretic transport, mainly because some of the hydrodynamic descriptions are incomplete from a thermodynamic point of view. In the present paper, we use a unified framework to describe diffusio-osmosis(phoresis), and we report non-equilibrium molecular dynamics (NEMD) on such systems. We explore different simulation methods to highlight some of the technical problems that arise in the calculations. For diffusiophoresis, we use two NEMD methods: boundary-driven and field-driven. Although the two methods should be equivalent in the limit of very weak gradients, we find that finite Peclet-number effects are much stronger in boundary-driven flows than in the case where we apply fictitious color forces.

description: Epithelial fusion, where two opposing epithelial sheets converge and combine to create a single continuous structure, occurs in the optic fissure (OF) during embryonic eye development. The OF is a ventral gap that runs along the entire proximal-distal axis of the developing optic cup. Fusion at the OF occurs around the 6th week of human development and its dysregulation results in ocular coloboma, the most frequent congenital eye defect and a leading cause of inherited childhood blindness in humans. The NTN1 gene encodes Netrin- 1, an extracellular laminin-related protein with evolutionary conserved roles as a facilitator of tissue fusion in multiple developmental contexts, including the OF. Previous research on Netrin-1 function has focused on its role in axon guidance, but emerging evidence has established the basis for a broader role in the regulation of epithelial cell behaviours, such as epithelial-to-mesenchymal transition, wound healing, and apoptosis, all features of tissue fusion. How the secretion of Netrin-1 in these contexts regulates cell behaviour is currently unknown, and is particularly restricted from a lack of knowledge of Netrin-1 binding partners at the cell surface, and how these combine to induce specific cellular responses. The aim of this study was therefore to develop a system to identify Netrin-1 protein binding partners and assess these for their in vivo relevance to tissue fusion during optic fissure closure. An inducible cell-system was generated to express Netrin-1 covalently linked to epitope tags to facilitate the isolation of Netrin-1 with its binding partners using co-immunoprecipitation. This thesis will describe the generation and validation of this system, describe steps to optimise its application and the preliminary results obtained. It will also include data analysis from experiments used to identify any transcriptional responses to the forced expression of Netrin- 1, testing the hypothesis that Netrin-1 is a regulator of epithelial-to-mesenchymal transition or other cell behaviours relevant to tissue fusion. This work provides a crucial first step in the discovery of Netrin-1 binding partners, and will be a valuable resource to determine to functional roles of NTN1 during tissue fusion.

Covalent probes for functional and structural characterization of glycoside hydrolases
Creators: name: Jain, Namrata
Publisher: name: University of British Columbia
Year: 2020

description: Carbohydrates are ubiquitous in Nature and fundamental to the sustenance of organisms across all domains of life. Carbohydrates serve as sources and reserves of metabolic energy, participate in various cellular communication events, and provide structural support to plant and animal cells. Highly specific enzymes have evolved over several millennia to bind and manipulate carbohydrate substrates. Glycoside hydrolases (GHs) are a class of carbohydrate-active enzymes that cleave glycosidic linkages in complex carbohydrates. Organisms across all domains of life dedicate part of their genome to the production of GHs. New GHs are continually discovered through genome sequencing, while their structural and functional characterization, particularly in complex native environments, poses a persistent challenge to the dynamic field of GH characterization. One of the fundamental ways of ascribing protein function is the exploration of protein active sites, which can be used to deduce important details regarding substrate-enzyme interactions. The work presented in this thesis describes the development of six new probes targeting a variety of GHs by irreversible covalent inhibition. These probes, developed on oligosaccharide scaffolds, feature either an N-bromoacetylglycosylamine electrophilic warhead or 2', 4' dinitrophenyl 2-deoxy-2-fluoro substitutions, facilitating irreversible inhibition of the target GH. The analysis presented in this work reveals key information about enzyme-inhibitor interactions through enzyme kinetic analyses, intact-protein mass spectrometry, and inhibitor-bound protein X-ray crystallography. Enzymes of diverse GH families and substrate preferences including endo-xyloglucanases, mixed-linkage glucanases, and β-(1,3) glucanases are featured to demonstrate the potency of this library of inhibitors. This small-molecule inhibitor toolkit targeting specific GH enzymes has the potential to enhance our knowledge of the structural and functional characteristics of GHs and to provide a platform for activity-based enzyme profiling.

description: In this paper, we consider the simplest class of stratified spaces -- linearly embedded graphs. We present an algorithm that learns the abstract structure of an embedded graph and models the specific embedding from a point cloud sampled from it. We use tools and inspiration from computational geometry, algebraic topology, and topological data analysis and prove the correctness of the identified abstract structure under assumptions on the embedding. The algorithm is implemented in the Julia package http://github.com/yossibokor/Skyler.jl , which we used for the numerical simulations in this paper.
5D supersymmetric domain wall solution with active hyperscalars and mixed AdS/non-AdS asymptotics

description: We find a new supersymmetric 5D solution of N = 2 supergravity coupled to one hypermultiplet that depends only on the fifth dimension (the energy scale in a holographic context). In one asymptotic limit the domain wall approaches to the AdS_5 form but in the other one does not. Similarly, the hyperscalars, which are all proportional between them, go asymptotically to a critical point of the potential only in one direction. The quaternionic Kahler manifold of the model is the H^4 hyperboloid. We use the standard metric of H^4 in an explicit conformally flat form with several arbitrary parameters. We argue that the holographic dual of the domain wall is a RG flow of an D = 4, N = 1 gauge theory acquiring a conformal supersymmetry at the IR limit, which correspond to the AdS_5 asymptotic limit.
description: A new section with a qualitative discussion about the holographic dual of the solution has been included. The conclusions have been rewritten and expanded. Other minor changes in wording and some references have been added. 30 pages, 2 figures

description: A five dimensional pure Yang--Mills theory, with the fifth coordinate compactified on the orbifold $S^1/Z_2$ of radius R, leads to a four dimensional theory which is governed by two types of local gauge transformations, namely, the well known standard gauge transformations (SGT) dictated by the $SU_4(N)$ group under which the zero Fourier modes transform as gauge fields, and a set of nonstandard gauge transformations (NSGT) determining the gauge nature of the Kaluza--Klein (KK) excitations. By using a SGT-covariant gauge-fixing procedure for removing the degeneration associated with the NSGT, we integrate out the KK excitations and obtain a low-energy effective Lagrangian expansion involving all of the independent canonical-dimension-six operators that are invariant under the SGT of the $SU_4(N)$ group and that are constituted by light gauge fields (zero modes), exclusively. It is shown that this effective Lagrangian is invariant under the SGT, but it depends on the gauge-fixing of the gauge KK excitations. Our result shows explicitly that the one-loop contributions of the KK excitations to light (standard) Green's functions are renormalizable.

description: Previously, the last two authors found large families of decomposable Specht modules labelled by bihooks, over the Iwahori--Hecke algebra of type $B$. In most cases we conjectured that these were the only decomposable Specht modules labelled by bihooks, proving it in some instances. Inspired by a recent semisimplicity result of Bowman, Bessenrodt and the third author, we look back at our decomposable Specht modules and show that they are often either semisimple, or very close to being so. We obtain their exact structure and composition factors in these cases. In the process, we determine the graded decomposition numbers for almost all of the decomposable Specht modules indexed by bihooks.

description: Let (M,g) be a compact n-dimensional Riemannian manifold with boundary. This article is concerned with the set of scalar-flat metrics on M which are in the conformal class of g and have the boundary as a constant mean curvature hypersurface. We construct examples of metrics on the unit ball, in dimensions n>=25, for which this set is noncompact. These manifolds have umbilic boundary, but they are not conformally equivalent to the unit ball.

description: The distributions of Grubbs statistics for outliers identification in samples of the half normal distribution have been tabulated. The Grubbs statistics quantiles are tested in methods for estimating parameters of stochastic models which arises for certain class of nonstationary random processes. A comparative analysis of the Grubbs statistics quantiles has been carried out. They were compared with Grubbs' estimates as well as with the estimates that the outliers library of the R-package yields.

Entanglement, decoherence and thermal relaxation in exactly solvable models

description: Exactly solvable models provide an opportunity to study different aspects of reduced quantum dynamics in detail. We consider the reduced dynamics of a single spin in finite XX and XY spin 1/2 chains. First we introduce a general expression describing the evolution of the reduced density matrix. This expression proves to be tractable when the combined closed system (i.e. open system plus environment) is integrable. Then we focus on comparing decoherence and thermalization timescales in the XX chain. We find that for a single spin these timescales are comparable, in contrast to what should be expected for a macroscopic body. This indicates that the process of quantum relaxation of a system with few accessible states can not be separated in two distinct stages - decoherence and thermalization. Finally, we turn to finite-size effects in the time evolution of a single spin in the XY chain. We observe three consecutive stages of the evolution: regular evolution, partial revivals, irregular (apparently chaotic) evolution. The duration of the regular stage is proportional to the number of spins in the chain. We observe a "quiet and cold period" in the end of the regular stage, which breaks up abruptly at some threshold time.

description: We explore the mass distribution of material associated with galaxies from the observation of gravitational weak lensing for the galaxy mass correlation function with the aid of $N$-body simulations of dark matter. The latter is employed to unfold various contributions that contribute to the integrated line of sight mass density. We conclude that galaxies have no definite edges of the matter distribution, extending to the middle to neighbouring galaxies with the density profile roughly $r^{-2.4}$ beyond the virial radius. The mass distributed beyond the virial radius (gravitationally bound radius) explains the gap seen in the mass density estimates, the global value $Ω_m\sim 0.27$ and typically $Ω_{\rm gal} \sim 0.15$ from the luminosity density multiplied by the mass to light ratio. We suggest to use a physical method of gravitational lensing to characterise galaxy samples rather than characterise them with photometric means.

description: Nowadays, many of the images captured are `observed' by machines only and not by humans, e.g., in autonomous systems. High-level machine vision models, such as object recognition or semantic segmentation, assume images are transformed into some canonical image space by the camera \ans{Image Signal Processor (ISP)}. However, the camera ISP is optimized for producing visually pleasing images for human observers and not for machines. Therefore, one may spare the ISP compute time and apply vision models directly to RAW images. Yet, it has been shown that training such models directly on RAW images results in a performance drop. To mitigate this drop, we use a RAW and RGB image pairs dataset, which can be easily acquired with no human labeling. We then train a model that is applied directly to the RAW data by using knowledge distillation such that the model predictions for RAW images will be aligned with the predictions of an off-the-shelf pre-trained model for processed RGB images. Our experiments show that our performance on RAW images for object classification and semantic segmentation is significantly better than models trained on labeled RAW images. It also reasonably matches the predictions of a pre-trained model on processed RGB images, while saving the ISP compute overhead.
Bi-galileon theory II: phenomenology

subject: FOS: Physical sciences

description: We continue to introduce bi-galileon theory, the generalisation of the single galileon model introduced by Nicolis et al. The theory contains two coupled scalar fields and is described by a Lagrangian that is invariant under Galilean shifts in those fields. This paper is the second of two, and focuses on the phenomenology of the theory. We are particularly interesting in models that admit solutions that are asymptotically self accelerating or asymptotically self tuning. In contrast to the single galileon theories, we find examples of self accelerating models that are simultaneously free from ghosts, tachyons and tadpoles, able to pass solar system constraints through Vainshtein screening, and do not suffer from problems with superluminality, Cerenkov emission or strong coupling. We also find self tuning models and discuss how Weinberg's no go theorem is evaded by breaking Poincaré invariance in the scalar sector. Whereas the galileon description is valid all the way down to solar system scales for the self-accelerating models, unfortunately the same cannot be said for self tuning models owing to the scalars backreacting strongly on to the geometry.
description: Erratum added presenting arguments similar in spirit to those presented in 1303.0274, and alluding to the inevitability of superluminality in the absence of strong coupling . We emphasize, however, that the generic formalism developed here, and extensively used in 1303.0274, is correct

description: We study the transport of quantum correlations across a chain of interacting spin-1/2 particles. As a quantitative figure of merit, we choose a symmetric version of quantum discord and compare it with the transported entanglement, addressing various operating regimes of the spin medium. Discord turns out to be better transported for a wide range of working points and initial conditions of the system. We relate this behavior to the efficiency of propagation of a single excitation across the spin chain. Moreover, we point out the role played by a magnetic field in the dynamics of discord in the effective channel embodied by the chain. Our analysis can be interestingly extended to transport processes in more complex networks and the study of non-classical correlations under general quantum channels.

Radiation Pressure Driven Galactic Winds from Self-Gravitating Discs

Publisher: name: arXiv
Year: 2010
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: (Abridged) We study large-scale winds driven from uniformly bright self-gravitating discs radiating near the Eddington limit. We show that the ratio of the radiation pressure force to the gravitational force increases with height above the disc surface to a maximum of twice the value of the ratio at the disc surface. Thus, uniformly bright self-gravitating discs radiating at the Eddington limit are fundamentally unstable to driving large-scale winds. These results contrast with the spherically symmetric case, where super-Eddington luminosities are required for wind formation. We apply this theory to galactic winds from rapidly star-forming galaxies that approach the Eddington limit for dust. For hydrodynamically coupled gas and dust, we find that the asymptotic velocity of the wind is v_\infty ~ 1.5 v_rot and that v_\infty SFR^{0.36}, where v_rot is the disc rotation velocity and SFR is the star formation rate, both of which are in agreement with observations. However, these results of the model neglect the gravitational potential of the surrounding dark matter halo and an old passive stellar bulge or extended disc, which act to decrease v_\infty. A more realistic treatment shows that the flow can either be unbound, or bound, forming a "fountain flow" with a typical turning timescale of t_turn ~ 0.1-1 Gyr. We provide quantitative criteria and scaling relations for assessing whether or not a rapidly star-forming galaxy of given properties can drive unbound flows via the mechanism described in this paper. Importantly, we note that because t_turn is longer than the star formation timescale in the rapidly star-forming galaxies and ULIRGs for which our theory is most applicable, if rapidly star-forming galaxies are selected as such, they may be observed to have strong outflows, even though their winds are eventually bound on large scales.

description: Given a set of well-formed terminal pairs on the external face of an undirected planar graph with unit edge weights, we give a linear-time algorithm for computing the union of non-crossing shortest paths joining each terminal pair, where well-formed means that such a set of non-crossing paths exists. This allows us to compute distances between each terminal pair, within the same time bound. We also give a novel concept of incremental shortest path subgraph of a planar graph, i.e., a partition of the planar embedding in subregions that preserve distances, that can be of interest itself.

description: I sistemi di mobilità condivisa si stanno evolvendo e diventano sempre più all’avanguardia grazie all’avanzamento della tecnologia, in particolare con l'affermarsi di veicoli elettrici, autonomi e grid-aware, cioè a conoscenza delle opportunità di ricarica nella rete elettrica. Simulare e valutare questo tipo di servizi è un attività di grande importanza in quanto permette di minimizzare i fallimenti nella loro pianificazione, riducendone i costi operativi, migliorandone l'efficienza e di conseguenza il loro impatto sull’ambiente. L’obiettivo di questo studio è quello di inventare, simulare e valutare scenari realistici che possano riflettere un sistema di mobilità innovativo in servizio nel nostro territorio. Per fare ciò è necessario determinare quali indicatori di efficienza è meglio utilizzare per valutare le soluzioni ottenute. Questi indicatori devono essere in grado di mostrarci quanto gli utenti saranno soddisfatti del servizio e a quanto ammontano i costi della ricarica dei veicoli. I risultati, ottenuti attraverso l'analisi di 16 scenari diversi contenenti fino a 240 richieste di trasporto, ci hanno permesso di analizzare il comportamento di un servizio a chiamata nel nostro territorio. Il progetto dunque può essere utilizzato come strumento per pianificare in modo dettagliato il possibile sviluppo di un servizio di mobilità grid-aware.

description: A high-voltage divider with accuracy at the ppm level and collinear laser spectroscopy were used to calibrate the highvoltage installation at the radioactive ion beam facility ISOLDE at CERN. The accurate knowledge of this voltage is particularly important for collinear laser spectroscopy measurements. Beam velocity measurements using frequencycomb based collinear laser spectroscopy agree with the new calibration. Applying this, one obtains consistent results for isotope shifts of stable magnesium isotopes measured using collinear spectroscopy and laser spectroscopy on laser-cooled ions in a trap. The long-term stability and the transient behavior during recovery from a voltage dropout were investigated for the different power supplies currently applied at ISOLDE.

description: Quantum Natural Language Processing (QNLP) deals with the design and implementation of NLP models intended to be run on quantum hardware. In this paper, we present results on the first NLP experiments conducted on Noisy Intermediate-Scale Quantum (NISQ) computers for datasets of size greater than 100 sentences. Exploiting the formal similarity of the compositional model of meaning by Coecke, Sadrzadeh and Clark (2010) with quantum theory, we create representations for sentences that have a natural mapping to quantum circuits. We use these representations to implement and successfully train NLP models that solve simple sentence classification tasks on quantum hardware. We conduct quantum simulations that compare the syntax-sensitive model of Coecke et al. with two baselines that use less or no syntax; specifically, we implement the quantum analogues of a "bag-of-words" model, where syntax is not taken into account at all, and of a word-sequence model, where only word order is respected. We demonstrate that all models converge smoothly both in simulations and when run on quantum hardware, and that the results are the expected ones based on the nature of the tasks and the datasets used. Another important goal of this paper is to describe in a way accessible to AI and NLP researchers the main principles, process and challenges of experiments on quantum hardware. Our aim in doing this is to take the first small steps in this unexplored research territory and pave the way for practical Quantum Natural Language Processing.

incertezza motoria legata all’ambiente

description: Il presente lavoro di ricerca, condotto presso una scuola dell'infanzia della valle Leventina, si focalizza sul bambino e sulle sue paure, insicurezze e abilità motorie relative ai movimenti di base (salto, arrampicata ed equilibrio). Lo scopo è osservare se un itinerario motorio svolto all’esterno permette di rafforzare la sicurezza e migliorare le competenze nei movimenti di base del bambino. Secondo diversi autori, l'educazione all’aperto può offrire un valore aggiunto allo sviluppo delle abilità motorie del bambino. Il contatto diretto con l’ambiente naturale può fornire maggiori stimoli e opportunità di apprendimento rispetto all'ambiente dell'aula. Per rispondere all’interrogativo che mi sono posta ho testato, tramite un pre-test, le competenze motorie di base dei bambini mentre svolgevano i percorsi relativi ai tre movimenti. Successivamente, sono state organizzate cinque uscite nel bosco in cui i bambini hanno svolto esercizi specifici per i tre movimenti. In seguito, è stato somministrato un post-test in cui i bambini hanno ripetuto gli stessi percorsi del pre-test, al fine di valutare l'impatto dell'esperienza sulle loro competenze motorie ed emotive. In conclusione, posso affermare che ho visto un grande miglioramento nei movimenti dei bambini e una maggiore sicurezza, come pure un maggior coraggio da parte loro nel gestirli. L’ambiente esterno si è rivelato un’opportunità per lo sviluppo fisico, mentale e sociale dei bambini. Relatore: Nicola Soldini.

description: We develop a new orbit equivalence framework for holomorphically mating the dynamics of complex polynomials with that of Kleinian surface groups. We show that the only torsion-free Fuchsian groups that can be thus mated are punctured sphere groups. We describe a new class of maps that are topologically orbit equivalent to Fuchsian punctured sphere groups. We call these higher Bowen-Series maps. The existence of this class ensures that the Teichmüller space of matings has one component corresponding to Bowen-Series maps and one corresponding to higher Bowen-Series maps. We also show that, unlike in higher dimensions, topological orbit equivalence rigidity fails for Fuchsian groups acting on the circle. We also classify the collection of Kleinian Bers boundary groups that are mateable in our framework.

Essays on the operations and management of transportation systems
Creators: name: Xia, Wenyi
Publisher: name: University of British Columbia
Year: 2020

description: This dissertation addresses three important issues in transportation and logistics, and provides insights for efficiently operating and managing transportation and logistics systems. The first essay (in Chapter 2) investigates the effects of airlines and high-speed rail (HSR) cooperation in a region with multiple airports. This essay is motivated by the rapid development of HSR, which has greatly promoted regional connectivity and air-rail intermodal transport. It shows under what conditions the air-rail cooperation is feasible, and how the air-rail cooperation can help relieve airport congestion. Specifically, when the HSR operator cares more about social welfare, or when the airlines are collusive, the airlines and HSR operator are more likely to cooperate. The air-rail cooperation helps to relieve airport congestion by diverting traffic to uncongested airports in the multiple-airport region. The second essay (in Chapter 3) investigates how seaports can better adapt to climate change by determining the optimal timing and scale of investments in protective measures and throughput capacity. This study is motivated by the alarming rate of global warming and the threats imposed to vulnerable transportation infrastructure. This essay takes into account the uncertainty about the probability and magnitude of climate-change-related disasters, the irreversibility of infrastructure investments, and information accumulation. This essay highlights the importance of considering the two types of investment (protection and capacity) together, because the seaport can adapt in different ways as future climate gets worse, such as investing more in protection, holding off capacity investment, or adjusting its fee. The third essay (in Chapter 4) proposes a new structural estimation approach which does not require individual choice data to estimate passengers’ mode choice of airport ground transportation. This approach is applied to Incheon International Airport. The estimation results suggest that passengers who fly Korean airlines or have experienced longer waiting times are less likely to take public transport. I formulate a nonlinear program that incorporates passengers’ choice behavior with the objective of maximizing train ridership. I show that the current train schedule is not efficiently matched with the intraday demand, and could be substantially improved to achieve higher ridership without adding trains.

description: Temperature and magnetic field studies of the elastic constants of the chromium spinel CdCr_2O_4 show pronounced anomalies related to strong spin-phonon coupling in this frustrated antiferromagnet. A detailed comparison of the longitudinal acoustic mode propagating along the [111] direction with theory based on an exchange-striction mechanism leads to an estimate of the strength of the magneto-elastic interaction. The derived spin-phonon coupling constant is in good agreement with previous determinations based on infrared absorption. Further insight is gained from intermediate and high magnetic field experiments in the field regime of the magnetization plateau. The role of the antisymmetric Dzyaloshinskii-Moriya interaction discussed and we compare the spin-phonon coupling in CdCr_2O_4 in both the ordered and disordered states.
