description: In this work, we derive a model for the covariance of the visual residuals in multi-view SfM, odometry and SLAM setups. The core of our approach is the formulation of the residual covariances as a combination of geometric and photometric noise sources. And our key novel contribution is the derivation of a term modelling how local 2D patches suffer from perspective deformation when imaging 3D surfaces around a point. Together, these add up to an efficient and general formulation which not only improves the accuracy of both feature-based and direct methods, but can also be used to estimate more accurate measures of the state entropy and hence better founded point visibility thresholds. We validate our model with synthetic and real data and integrate it into photometric and feature-based Bundle Adjustment, improving their accuracy with a negligible overhead.

Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We describe how optical dressing can be used to generate bandstructures for ultracold atoms with non-trivial Z_2 topological order. Time reversal symmetry is preserved by simple conditions on the optical fields. We first show how to construct optical lattices that give rise to Z_2 topological insulators in two dimensions. We then describe a general method for the construction of three-dimensional Z_2 topological insulators. A central feature of our approach is a new way to understand Z_2 topological insulators starting from the nearly-free electron limit.

description: Objective: This study sought to characterize the epidemiologic, clinical, humanistic, and economic burden of patients with asthma uncontrolled by GINA Steps 4 or 5 treatment (severe, uncontrolled asthma [SUA]). Methods: A systematic literature review adhering to PRISMA guidelines was performed. Relevant publications were searched for in MEDLINE and EMBASE from January 2004 to September 2016 and in a conference proceedings database from January 2012 to October 2016. Studies were screened using the Population, Intervention, Comparator, Outcomes, Study Design, and Time (PICOS-T) framework. Studies of SUA with observational (prospective and retrospective), randomized, or nonrandomized study designs; adult patient populations; sample sizes ≥20 patients; epidemiologic or clinical outcomes, patient-reported outcomes (PROs), or economic outcomes were included. For our analysis, SUA was defined as inadequate control of asthma, despite the use of medium- to high-dosage inhaled corticosteroids and at least one additional treatment. Results: A total of 195 articles reporting unique study populations were included. Prevalence of SUA was as great as 87.4% for patients with severe asthma, although values varied depending on the criteria used to define asthma control. Compared with patients with severe asthma who were controlled, patients with SUA experienced more symptoms, night-time awakenings, rescue medication use, and worse PROs. SUA-associated costs were 3-times greater than costs for patients with severe, controlled disease. Conclusion: Despite the availability of approved asthma treatments, this literature analysis confirms that SUA poses a substantial epidemiologic, clinical, humanistic, and economic burden. Published data are limited for certain aspects of SUA, highlighting a need for further research.
Autorità, contratto e autorità esperto: confronto tra differenti posture nell'insegnamento di due classi di scuola media ticinese

description: L'evoluzione della società richiede alla scuola di tenere conto delle nuove necessità che ne derivano. Oltre all'acquisizione di informazioni e conoscenze, gli allievi devono essere in grado di agire in modo attivo e creativo in situazioni complesse e non prevedibili. Il piano di studio della scuola media ticinese si propone di formare futuri individui capaci di diventare adulti e cittadini responsabili, integrati e autonomi. La ricerca ha analizzato l'effetto dell'autorità esperto e dell'autorità di contratto del docente sul coinvolgimento degli allievi e la qualità del prodotto finale oltre che le competenze trasversali di comunicazione, collaborazione e autonomia. Si è concluso che l'autorità esperto è utile per accrescere le competenze disciplinari e produrre prodotti finali accurati, mentre l'autorità di contratto è efficace per sviluppare competenze trasversali come l'autonomia, la responsabilità e la collaborazione. La valutazione del coinvolgimento degli allievi e del prodotto finale si basa su un giudizio personale e la ricerca sarebbe migliorata coinvolgendo un gruppo di allievi più numeroso e una figura esterna e indipendente. L'applicazione delle teorie anarchiche nel contesto scolastico richiederebbe un cambiamento di mentalità del corpo insegnanti, ma è in linea con le direttive pedagogiche della scuola e con la formazione di futuri cittadini responsabili ed equilibrati.

Uniform synchronization of an abstract linear second order evolution system

description: Although the mathematical study on the synchronization of wave equations at finite horizon has been well developed, there was few results on the synchronization of wave equations for long-time horizon. The aim of the paper is to investigate the uniform synchronization at the infinite horizon for one abstract linear second order evolution system in a Hilbert space. First, using the classical compact perturbation theory on the uniform stability of semigroups of contractions, we will establish a lower bound on the number of damping, necessary for the uniform synchronization of the considered system. Then, under the minimum number of damping, we clarify the algebraic structure of the system as well as the necessity of the conditions of compatibility on the coupling matrices. We then establish the uniform synchronization by the compact perturbation method and then give the dynamics of the asymptotic orbit. Various applications are given for the system of wave equations with boundary feedback or (and) locally distributed feedback, and for the system of Kirchhoff plate with distributed feedback. Some open questions are raised at the end of the paper for future development. The study is based on the synchronization theory and the compact perturbation of semigroups.

description: We study the Chiral Separation Effect (CSE) in finite-density SU(2) lattice gauge theory withdynamical quarks. We find that the CSE is well described by the free quark result in the high-temperature quark-gluon plasma phase. As one enters the confinement regime with broken chiralsymmetry at chemical potential smaller than half of the pion mass, the CSE response is graduallysuppressed towards low temperatures in comparison to the free quark result. This suppression canbe approximately described by assuming that the CSE current is proportional to the charge density,rather than the chemical potential, as suggested in the literature [Phys. Rev. D 97, 085020 (2018)].We also provide an upper bound on the contribution of disconnected fermionic diagrams to theCSE, which is consistent with zero within our statistical errors and small compared to that of theconnected diagrams. Our results are obtained mainly in the QCD-like regime of SU(2) gauge theoryat low densities, and hence should be at least qualitatively applicable to QCD as well.

The Boundary Multiplet of N=4 SU(2)xU(1) Gauged Supergravity on Asymptotically-AdS_5

description: We consider N=4 SU(2)xU(1) gauged supergravity on asymptotically-AdS_5 backgrounds. By a near-boundary analysis we determine the boundary-dominant components of the bulk fields from their partially gauge-fixed field equations. Subdominant components are projected out in the boundary limit and we find a reduced set of boundary fields, constituting the N=2 Weyl multiplet. The residual bulk symmetries are found to act on the boundary fields as four-dimensional diffeomorphisms, N=2 supersymmetry and (super-)Weyl transformations. This shows that the on-shell N=4 supergravity multiplet yields the N=2 Weyl multiplet on the boundary with the appropriate local N=2 superconformal transformations. Building on these results we use the AdS/CFT conjecture to calculate the Weyl anomaly of the dual four-dimensional superconformal field theories in a generic bosonic N=2 conformal supergravity background.

A Short GRB "No-Host'' Problem? Investigating Large Progenitor Offsets for Short GRBs with Optical Afterglows
Creators: name: Berger, E.
Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: [abridged] We investigate the afterglow properties and large-scale environments of several short-duration gamma-ray bursts (GRBs) with sub-arcsecond optical afterglow positions but no bright coincident host galaxies. The purpose of this joint study is to robustly assess the possibility of significant offsets, a hallmark of the compact object binary merger model. Five such events exist in the current sample of 20 short bursts with optical afterglows, and we find that their optical, X-ray, and gamma-ray emission are systematically fainter. These differences may be due to lower circumburst densities (by about an order of magnitude), to higher redshifts (by dz~0.5-1), or to lower energies, although in the standard GRB model the smaller gamma-ray fluences cannot be explained by lower densities. To study the large-scale environments we use deep optical observations to place limits on underlying hosts and to determine probabilities of chance coincidence for galaxies near each burst. In 4 of the 5 cases the lowest probabilities of chance coincidence (P(1 leads to offsets of ~15 kpc. Alternatively, the limits at the burst positions (>26 mag) can be explained by typical short GRB host galaxies (L~0.1-1 L*) at z>2. Thus, two possibilities exist: (i) ~1/4 of short GRBs explode ~50 kpc or ~15 kpc from the centers of z~0.3 or z>1 galaxies, respectively, and have fainter afterglows due to the resulting lower densities; or (ii) ~1/4 of short GRBs occur at z>2 and have fainter afterglows due to their higher redshifts.

On the Relation between Realizable and Nonrealizable Cases of the Sequence Prediction Problem

description: A sequence $x_1,\dots,x_n,\dots$ of discrete-valued observations is generated according to some unknown probabilistic law (measure) $μ$. After observing each outcome, one is required to give conditional probabilities of the next observation. The realizable case is when the measure $μ$ belongs to an arbitrary but known class $\mathcal C$ of process measures. The non-realizable case is when $μ$ is completely arbitrary, but the prediction performance is measured with respect to a given set $\mathcal C$ of process measures. We are interested in the relations between these problems and between their solutions, as well as in characterizing the cases when a solution exists and finding these solutions. We show that if the quality of prediction is measured using the total variation distance, then these problems coincide, while if it is measured using the expected average KL divergence, then they are different. For some of the formalizations we also show that when a solution exists, it can be obtained as a Bayes mixture over a countable subset of $\mathcal C$. We also obtain several characterization of those sets $\mathcal C$ for which solutions to the considered problems exist. As an illustration to the general results obtained, we show that a solution to the non-realizable case of the sequence prediction problem exists for the set of all finite-memory processes, but does not exist for the set of all stationary processes. It should be emphasized that the framework is completely general: the processes measures considered are not required to be i.i.d., mixing, stationary, or to belong to any parametric family.

Extended Clausius Relation and Entropy for Nonequilibrium Steady States in Heat Conducting Quantum Systems

description: Recently, in their attempt to construct steady state thermodynamics (SST), Komatsu, Nakagwa, Sasa, and Tasaki found an extension of the Clausius relation to nonequilibrium steady states in classical stochastic processes. Here we derive a quantum mechanical version of the extended Clausius relation. We consider a small system of interest attached to large systems which play the role of heat baths. By only using the genuine quantum dynamics, we realize a heat conducting nonequilibrium steady state in the small system. We study the response of the steady state when the parameters of the system are changed abruptly, and show that the extended Clausius relation, in which "heat" is replaced by the "excess heat", is valid when the temperature difference is small. Moreover we show that the entropy that appears in the relation is similar to von Neumann entropy but has an extra symmetrization with respect to time-reversal. We believe that the present work opens a new possibility in the study of nonequilibrium phenomena in quantum systems, and also confirms the robustness of the approach by Komtatsu et al.

Il paesaggio geomorfologico: per una didattica dei geositi
Creators: name: Bocchi, Attilio
Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2017

description: L’argomento principale di questo lavoro di diploma riguarda l’analisi e la lettura del paesaggio e costituisce una prima tappa nella promozione del lavoro sul terreno. Tale approccio riprende l’immagine del ‘territorio-laboratorio’. Lo scopo è di indagare, attraverso la metodologia della ricerca-azione, se il lavoro sul terreno, tramite l’osservazione diretta, può rappresentare una metodologia efficace per la comprensione del paesaggio geomorfologico, rispetto all’osservazione indiretta effettuata in classe per mezzo di materiali. In particolare, il percorso didattico, che si rivolge a una classe di seconda liceo, affronta l’argomento del paesaggio geomorfologico, attraverso una didattica dei geositi. Nonostante alcuni elementi di criticità relativi al tempo a disposizione e all’organizzazione del lavoro sul terreno, lo studio evidenzia come i traguardi formativi dichiarati siano stati raggiunti con soddisfazione. Dal questionario di apprezzamento sottoposto alla classe, emerge generalmente che gli allievi apprezzano la possibilità di confrontarsi « faccia a faccia con il paesaggio ». Tale condizione crea le premesse per favorire la lettura del territorio e la capacità di riconoscere le relazioni che alcuni elementi di quest’ultimo intrattengono tra di loro. Le analisi dei risultati evidenziano altresì che l’osservazione diretta e quella indiretta costituiscono due approcci fra di loro complementari, di cui la pratica didattica dovrebbe avvalersi in modo rigoroso e regolare.

description: We investigate supercurrent-induced magnetization dynamics in a Josephson junction with two misaligned ferromagnetic layers, and demonstrate a variety of effects by solving numerically the Landau-Lifshitz-Gilbert equation. In particular, we demonstrate the possibility to obtain supercurrent-induced magnetization switching for an experimentally feasible set of parameters, and clarify the favorable condition for the realization of magnetization reversal. These results constitute a superconducting analogue to conventional current-induced magnetization dynamics and indicate how spin-triplet supercurrents may be utilized for practical purposes in spintronics.

description: The aim of the work is to study the methods of machine learning in relation to the recognition of urban structures and the development of an appropriate software module using convolutional neural network. The developed module will be used in the framework of a mobile application with augmented reality for the iOS operating system.

description: We propose a scheme to explore regimes of strong-field quantum electrodynamics (SF QED) otherwise unattainable with the currently available laser technology. The scheme relies on relativistic plasma mirrors curved by radiation pressure to boost the intensity of petawatt-class laser pulses by Doppler effect and focus them to extreme field intensities. We show that very clear SF QED signatures could be observed by placing a secondary target where the boosted beam is focused.

description: This is an expository paper on approximating functions from general Hilbert or Banach spaces in the worst case, average case and randomized settings with error measured in the $L_p$ sense. We define the power function as the ratio between the best rate of convergence of algorithms that use function values over the best rate of convergence of algorithms that use arbitrary linear functionals for a worst possible Hilbert or Banach space for which the problem of approximating functions is well defined. Obviously, the power function takes values at most one. If these values are one or close to one than the power of function values is the same or almost the same as the power of arbitrary linear functionals. We summarize and supply a few new estimates on the power function. We also indicate eight open problems related to the power function since this function has not yet been studied for many cases. We believe that the open problems will be of interest to a general audience of mathematicians.

description: The “Facility for Antiproton and Ion Research” (FAIR) in Darmstadt will provide unique research opportunities for the investigation of fundamental open questions related to nuclear physics and astrophysics, including the exploration of QCD matter under extreme conditions, which governs the structure and dynamics of cosmic objects and phenomena like neutron stars, supernova explosions, and neutron star mergers. The physics program of the Compressed Baryonic Matter (CBM) experiment is devoted to the production and investigation of dense nuclear matter, with a focus on the high-density equation-of-state (EOS), and signatures for new phases of dense QCD matter. According to the present schedule, the CBM experiment will receive the first beams from the FAIR accelerators in 2025. This article reviews promising observables, outlines the CBM detector system, and presents results of physics performance studies.
Active motion assisted by correlated stochastic torques

description: The stochastic dynamics of an active particle undergoing a constant speed and additionally driven by an overall fluctuating torque is investigated. The random torque forces are expressed by a stochastic differential equation for the angular dynamics of the particle determining the orientation of motion. In addition to a constant torque, the particle is supplemented by random torques which are modeled as an Ornstein-Uhlenbeck process with given correlation time $τ_c$. These nonvanishing correlations cause a persistence of the particles' trajectories and a change of the effective spatial diffusion coefficient. We discuss the mean square displacement as a function of the correlation time and the noise intensity and detect a nonmonotonic dependence of the effective diffusion coefficient with respect to both correlation time and noise strength. A maximal diffusion behavior is obtained if the correlated angular noise straightens the curved trajectories, interrupted by small pirouettes, whereby the correlated noise amplifies a straightening of the curved trajectories caused by the constant torque.

description: Centrality dependence of the directed flow of protons in Au+Au collisions at the beam energy of 1.23A GeV collected by the HADES experiment at GSI is presented. Measurements are performed with respect to the spectators plane estimated using the Forward Wall hodoscope. Biases due to non-flow correlations and correlated detector effects are evaluated. The corresponding systematic uncertainties are quantified using estimates of the spectators plane from various forward rapidity regions constructed from groups of Forward Wall channels and protons reconstructed with the HADES tracking system.

description: In this paper we prove a discrete version of Tanaka's Theorem \cite{Ta} for the Hardy-Littlewood maximal operator in dimension $n=1$, both in the non-centered and centered cases. For the discrete non-centered maximal operator $\widetilde{M} $ we prove that, given a function $f: \mathbb{Z} \to \mathbb{R}$ of bounded variation, $$\textrm{Var}(\widetilde{M} f) \leq \textrm{Var}(f),$$ where $\textrm{Var}(f)$ represents the total variation of $f$. For the discrete centered maximal operator $M$ we prove that, given a function $f: \mathbb{Z} \to \mathbb{R}$ such that $f \in \ell^1(\mathbb{Z})$, $$\textrm{Var}(Mf) \leq C \|f\|_{\ell^1(\mathbb{Z})}.$$ This provides a positive solution to a question of Hajłasz and Onninen \cite{HO} in the discrete one-dimensional case.

High-throughput analysis using novel sample preparation method and direct analysis in real time mass spectrometry
Creators: name: Jing, Wenqiang
Publisher: name: University of British Columbia
Year: 2020

description: Qualitative and quantitative determination of trace compounds in complex samples is critically important in all fields of scientific research. The direct coupling of suitable sample preparation methods and direct analysis in real time mass spectrometry (DART-MS) has been shown to be a promising solution to trace analysis of compounds in complex matrices. In Chapter 1, a technical introduction of DART-MS and a review of some of the most common sample preparation techniques in trace analysis are presented. The coupling of sample preparation and DART-MS are also briefly reviewed in this chapter. Chapter 2 presents the direct coupling of dispersive magnetic solid-phase extraction (DMSPE) to DART-MS using a metal iron probe and its application in the trace analysis of six triazine herbicides in aqueous environmental samples. The ratio of magnetic core to graphene oxide in the sorbents and other key parameters in both DMSPE and DART-MS were investigated and optimized. This developed method combined the advantages of these two analytical techniques, and good analytical performance was achieved. In Chapter 3, a sorbent and solvent co-enhanced DART-MS method (SSE-DART-MS) was demonstrated for the determination of trace phthalic acid esters (PAEs) in water. Six common organic solvents were added on to two graphitic carbon nitride-based materials (g-C₃N₄) with different morphologies to study the enhancement effect. In Chapter 4, nine silica-supported ionic liquids (ILs) with different hydrophobicity were synthesized. They were then used separately as coatings for the solid-phase microextraction of five PAEs followed by DART-MS analysis to study how the hydrophobicity of sorbents influence the signals of analytes in DART-MS, and further investigation is needed to verify the general trend. In Chapter 5, the principle of deep eutectic solvent-based microwave-assisted extraction (DES-MAE) was systematically studied. The study also showed that in most cases, adding water will reduce the heating efficiency of DES under microwave irradiation, and DES containing carboxylic acid may react with cellulose, hemicellulose, and lignin to promote cell wall destruction. Chapter 6 summarizes the work presented and provides a brief outlook for future directions.

description: We study the changes in the spatial distribution of vortices in a rotating Bose-Einstein condensate due to an increasing anisotropy of the trapping potential. Once the rotational symmetry is broken, we find that the vortex system undergoes a rich variety of structural changes, including the formation of zig-zag and linear configurations. These spatial re-arrangements are well signaled by the change in the behavior of the vortex-pattern eigenmodes against the anisotropy parameter. The existence of such structural changes opens up possibilities for the coherent exploitation of effective many-body systems based on vortex patterns.

description: We discuss gravitational physics in the Jordan and Einstein frames of $f (R)$ gravity coupled to the Standard Model. We elucidate the way in which the observed gravitational coupling arises in the Einstein frame for generic $f (R)$. We point out that the effect of "running units" in the Einstein frame is related to the fact that the explicit and implicit quantum parameters of the Standard Model, such as the Higgs vacuum expectation value and the parameter $Λ_\text{QCD}$, are modified by the conformal transformation of the metric and matter fields and become scalaron-dependent. Considering the scalaron of $f (R)$ gravity describing dark matter, we show that the effect of running units in this case is extremely weak, making two frames practically equivalent.

Il prospetto nord-orientale del castello, specifico oggetto di studio di questa ricerca, è stato individuato in virtù della sua conformazione e delle sue peculiarità, in quanto mostra sulla superficie non solo una stratificazione materica molto ricca e databile dalla fine del XV secolo a oggi, ma anche la sintesi espressiva di tutto l’intervento di restauro di inizio Novecento compiuto dal pittore e restauratore Edoardo Berta.

description: An important goal within the quest for detecting an Earth-like extrasolar planet, will be to identify atmospheric gaseous bio-signatures. Observations of the light transmitted through the Earth's atmosphere, as for an extrasolar planet, will be the first step for future comparisons. We have completed observations of the Earth during a Lunar eclipse, a unique situation similar to that of a transiting planet. We aim at showing what species could be detected in its atmosphere at optical wavelengths, where a lot of photons are available in the masked stellar light. We present observations of the 2008 August 16 Moon eclipse performed with the SOPHIE spectrograph at the Observatoire de Haute-Provence. Locating the spectrograph fibers in the penumbra of the eclipse, the Moon irradiance is then a mix of direct, unabsorbed Sun light and solar light that has passed through the Earth's limb. This mixture essentially reproduces what is recorded during the transit of an extrasolar planet. We report here the clear detection of several Earth atmospheric compounds in the transmission spectra, such as ozone, molecular oxygen, and neutral sodium as well as molecular nitrogen and oxygen through the Rayleigh signature. Moreover, we present a method that allows us to derive the thickness of the atmosphere versus the wavelength for penumbra eclipse observations. We quantitatively evaluate the altitude at which the atmosphere becomes transparent for important species like molecular oxygen and ozone, two species thought to be tightly linked to the presence of life. The molecular detections presented here are an encouraging first attempt, necessary to better prepare for the future of extremely-large telescopes and transiting Earth-like planets. Instruments like SOPHIE will be mandatory when characterizing the atmospheres of transiting Earth-like planets from the ground and searching for bio-marker signatures.

description: From the demand-side perspective, the monetary value of one additional quality-adjusted life year (QALY) is estimated as willingness-to-pay per QALY (WTPQ). This study aims to summarize the methods and contexts of elicitation of willingness-to-pay per quality-adjusted life year (WTPQ) in the general population and to investigate the heterogeneity of WTPQ estimates. Meta-regression analysis was conducted using Comprehensive Meta-Analysis Software. Sensitivity analyses were undertaken by replacing the lowest and highest 5% and 2.5% of WTPQ by percentiles. 33 studies with 102 WTPQ estimates were included. The overall mean and median WTPQ estimates are $1,280,002 and $44,072, respectively. The meta-regressions demonstrated that types of health gain (quality of life or life length) and certainty of health outcomes are statistically significant factors. Furthermore, compared with online interviews, face-to-face interviews tend to yield lower WTPQ. Moreover, the declining trend of QALY gains and positive effect with statistical significance of the sample age were also noticed. For valid and representative values of WTPQ, future researchers should therefore take into consideration various scenarios and investigate both health gain with certainty and uncertainty, health gain from both life length and quality of life, and different size of QALY gains.

description: We consider the line planning problem in public transportation, under a robustness perspective. We present a mechanism for robust line planning in the case of multiple line pools, when the line operators have a different utility function per pool. We conduct an experimental study of our mechanism on both synthetic and real-world data that shows fast convergence to the optimum. We also explore a wide range of scenarios, varying from an arbitrary initial state (to be solved) to small disruptions in a previously optimal solution (to be recovered). Our experiments with the latter scenario show that our mechanism can be used as an online recovery scheme causing the system to re-converge to its optimum extremely fast.
