description: We assess the possibility to detect the warm-hot intergalactic medium (WHIM) in emission and to characterize its physical conditions and spatial distribution through spatially resolved X-ray spectroscopy, in the framework of the recently proposed DIOS, EDGE, Xenia, and ORIGIN missions, all of which are equipped with microcalorimeter-based detectors. For this purpose we analyze a large set of mock emission spectra, extracted from a cosmological hydrodynamical simulation. These mock X-ray spectra are searched for emission features showing both the OVII K alpha triplet and OVIII Ly alpha line, which constitute a typical signature of the warm hot gas. Our analysis shows that 1 Ms long exposures and energy resolution of 2.5 eV will allow us to detect about 400 such features per deg^2 with a significance >5 sigma and reveals that these emission systems are typically associated with density ~100 above the mean. The temperature can be estimated from the line ratio with a precision of ~20%. The combined effect of contamination from other lines, variation in the level of the continuum, and degradation of the energy resolution reduces these estimates. Yet, with an energy resolution of 7 eV and all these effects taken into account, one still expects about 160 detections per deg^2. These line systems are sufficient to trace the spatial distribution of the line-emitting gas, which constitute an additional information, independent from line statistics, to constrain the poorly known cosmic chemical enrichment history and the stellar feedback processes.

description: The international student experience presents an interesting and complex case in which a student must adjust to a new environment. Informed by poststructural theories, this exploratory study aimed to gain an in-depth understanding of eight Saudi international students’ linguistic, cultural, and identity experiences while living in Canada. It examined how Saudi students’ linguistic and cultural transitions within Canada relate to their L2 learning. To conduct this study, narrative inquiry was adopted as a methodology to gather narratives from Saudi participants by conducting semi-structured interviews. In the first part of the findings, using thematic analysis, I found nine emergent themes that revealed participants’ cultural/linguistic challenges, e.g., language anxiety and problems with academic English, and demonstrated participants’ difficulties socializing in their new L2 communities. In the second part of the findings, a narrative co-construction of one Saudi female participant’s life story in Canada revealed that gender-related issues were a central theme in Saudi female students’ integration. Linking all these emergent themes to poststructural L2 acquisition (SLA) theory, four key conclusions about the Saudi international student experience were brought to light: 1) Saudi participants faced challenges in building an academic identity in which they could participate confidently; 2) the formation of a non-native speaker identity impacted their ability to fully participate in the L2 community; 3) while attempting to gain access to the L2 community, some participants found themselves constrained and secluded by what they perceived as a lack of communicative competence; and 4) female participants talked about the re-negotiation of the Saudi female identity throughout their stay in Canada. Given these conclusions, this study carries various policy implications through which university administrators can build support services and foster international student inclusion.
Disagio a scuola e rendimento scolastico

description: Questa ricerca si prefigge di indagare, attraverso la somministrazione di due questionari e l’osservazione diretta, il disagio provato dai giovani e il loro rendimento scolastico. Inizialmente, i dati raccolti attraverso gli items 53 – 60 del questionario a scelta multipla hanno evidenziato la frequenza con la quale gli allievi incorrono nel bullismo e come percepiscono il proprio corpo. Le informazioni raccolte permettono di identificare in che misura gli studenti provano disagio e permettono di progettare un breve itinerario storico-didattico di sensibilizzazione . Per comprendere nello specifico quali siano le ragioni che alimentano il disagio e capire quanto sia stata utile la sensibilizzazione sulla diversità che caratterizza le persone, è stato somministrato un secondo questionario redatto appositamente per la classe campione. Fungono da quadro teorico alcuni testi riguardanti la famiglia e gli atteggiamenti degli adolescenti, mentre per la prevenzione al bullismo sono stati consultati degli opuscoli svizzeri e dei giornali ticinesi. In conclusione lo studio dedica un capitolo a due persone che si occupano di prevenzione nelle scuole: il Sgtm. Giancarlo Piffero della Polizia cantonale e il docente, organizzatore di MidnightSports, Alessandro Zanetti. Le interviste donano una visione globale della situazione ticinese ed evidenziano la necessità di operare a livello scolastico per prevenire atti di bullismo e per sensibilizzare i giovani. L’analisi dei risultati emersi e l’applicazione dell’itinerario permettono di affermare che il campione analizzato non si denota come un gruppo problematico e caratterizzato da relazioni di forza e soggezione, ma capace di discostarsi dal proprio punto di vista.

Community detection in networks : methods and biomedical applications

Publisher: name: University of British Columbia

description: Community detection is an emerging topic in modern network science. This thesis focuses on developing data-driven network generation and community extraction tools targeted for biomedical research, which is hardly studied in the literature, owing to the struggle of approaches to overcome resolution limitations without prior information. In the first part of this thesis, a novel community detection approach is proposed to detect unknown community structure from both binary and non-binary networks. The method overcomes the resolution limitation of current approaches, while no prior information regarding the community structure is available. In the later parts of the thesis, three common biomedical scenarios are identified where domain-dependent network community extraction frameworks are proposed to solve open research challenges. The first setting represents the scenario when no prior information regarding the community structure is available, and as an illustrative example, we consider the functional segmentation of brainstem from fMRI timecourses. We propose a framework to extract functional communities within the brainstem, based on a data-driven generation and clustering of the functional network, and a consensus based group model development approach. In the second scenario, at the presence of additional information, a domain-specific framework is proposed to incorporate prior information in the network community extraction pipeline. As an illustrative example we consider the parcellation of putaminal sub-regions, and propose a robust community extraction framework where a primary brain region is parcellated into functional sub-regions incorporating prior information regarding the number of communities, the connectivity differences both within and outside the primary network and a constraint on spatial contiguity. In the final setting community extraction from a large-scale dataset is considered, and a unified approach is proposed to combine network community detection to the deep-learning based framework to form deep-communities, and its potential to be used as a deep-clustering tool is illustrated on a chest X-ray based image retrieval study. We propose a framework that integrates a deep learning-based image-network generation approach and a weighted modularity based network-community detection technique to form similar image communities. A region-growing based community formation framework is then applied to extract similar images at the presence of a new image.

description: We study the stability of the equilibrium position of systems containing liquid - tanks. A number of problems were considered, in most of which only the condition of stability of a symmetric equilibrium was obtained. The most in-depth study was carried out for the triangular bucket problem. In it there are 4 configurations for which the boundaries of their existence were found, an expression for the potential energy in each of them was obtained. After that, the potential energy function is piecewise constructed, the possible equilibrium positions, their stability are analyzed. All results were obtained strictly analytically using the mathematical apparatus and the Lagrange-Dirichlet theorem on the condition of stability of the equilibrium position.

Das Kodiermanual wurde im Rahmen einer Studie zur Untersuchung naturwissenschaftlicher Erkenntnisgewinnungsprozesse von Studierenden im Labor (Sonnenschein, 2019) an der Humboldt-Universität zu Berlin entwickelt und umfassend validiert. Es ermöglicht die Abbildung von Erkenntnisgewinnungsprozessen, die Proband*innen in Reallaborumgebungen zeigen, auf Basis von schriftlich oder auditiv fixierten verbalen Daten. Das Manual wurde auf Grundlage des Modells wissenschaftlichen Denkens von Mayer (2007), welches im Rahmen dieser Studie um die Prozessvariable der Durchführung und die Personenvariable der metakognitiven Planung, Steuerung und Regulation des Experimentierprozesses erweitert wurde, entwickelt. Grundlegend beschreibt das Modell die Teilprozesse des Erkenntnisgewinnungsprozesses und orientiert sich an dem Verständnis von Erkenntnisgewinnung als iterativer Prozess der naturwissenschaftlich-experimentellen Problemlösung.

description: A parallel implementation of the Balancing Domain Decomposition by Constraints (BDDC) method is described. It is based on formulation of BDDC with global matrices without explicit coarse problem. The implementation is based on the MUMPS parallel solver for computing the approximate inverse used for preconditioning. It is successfully applied to several problems of Stokes flow discretized by Taylor-Hood finite elements and BDDC is shown to be a promising method also for this class of problems.

Impact of harvested wood products consumption strategies on British Columbia's greenhouse gas emissions
Creators: name: Xie, Sheng Hao
Publisher: name: University of British Columbia
Year: 2020

description: Keeping global temperature increases to below 2 ℃ will require reducing emissions and enhancing sinks and forest product uses can contribute. This research quantitatively compared the greenhouse gas (GHG) emission consequences of various harvested wood products (HWPs) utilization and export strategies for British Columbia’s (BC) bioeconomy. A state-of-the-art model, MitigAna, was developed to enable scenario-based mitigation analysis for HWPs with modules calculating substitution benefits and cascading uses. Timber construction and wood-based biofuels were identified as important contributors to GHG mitigation. Construction was the most climatically efficient utilization of HWPs because of its longer carbon storage and larger displacement factor than other applications. However, BC does not currently have sufficient international market access to fully realize the mitigation potential of a construction-focused bioeconomy, whereas available biofuel displacement markets would be sufficient to provide promising substitution benefits if technology to produce biofuels from woody biomass becomes available at a commercial scale. GHG mitigation can be achieved by promoting wood buildings for future construction and shifting biomass supply from short-lived exports, such as pulp and wood pellets, to biofuel production, and mandating that these biofuels displace fossil fuels. This strategy would mitigate on average 17.4 MtCO2e year⁻¹ between 2016 and 2050, which is equivalent to about 34% of BC's 2050 reduction targets. This would involve building the same floor area as at present, but the domestic market share of timber construction would need to double at the expense of concrete and steel. Redirecting biomass feedstock from exported pulp and wood pellets, 4.4 billion L year⁻¹ "drop-in" biofuels would be produced, equivalent to 50% of the energy demand in BC's transportation sector. This strategy may be a promising pathway for BC to achieve significant decarbonization in the transportation sector. However, if international collaborations on future wood buildings were in place, BC's HWP sector could make a maximum global mitigation contribution of 66 MtCO2e year⁻¹. This indicates that potential conflict exits between BC-specific benefits and maximizing the global GHG mitigation outcome. International policies and accounting rules can influence the desired global mitigation outcomes.

description: Matched-filtering (template-matching) is an effective method for detecting clustered seismicity such as aftershocks, low-frequency earthquakes, repeating earthquakes, and tectonic and volcanic swarms. Several groups have developed efficient codes implementing matched-filter methods and demonstrated that earthquake catalogs can be substantially expanded using these methods. Here, we present a near-real-time implementation of the matched-filter method, designed to be used in response to ongoing seismicity. Its near-real-time capabilities enable dense catalogs of seismicity to be constructed rapidly, providing input into real-time seismic hazard and forecasting and thus informing the earthquake response and scientific understanding. Such rapid development of detailed earthquake catalogs has similar application in volcano monitoring, monitoring of induced seismicity, and for online construction of slow-earthquake catalogs. Our software package, RT-EQcorrscan, is an open-source extension of the EQcorrscan Python package. The package can either be deployed to apply near-realtime matched-filters to a specific geographic region or sequence on a continuous basis, or configured to respond to large earthquakes or high-rate sequences by automatically starting a matched-filter run in response to these events. The system relies on, and maintains, a constantly updated template database of waveforms and event metadata, which is then queried for the specific target region. This template database can be updated while the matched-filter is running to enable the set of templates to expand in response to previous results. Multiple region-specific matched-filters can be run in parallel, allowing the system to respond to distinct trigger events.

We present several results that are relevant for the question of whether the evolution equations are hyperbolic, strongly hyperbolic or symmmetric hyperbolic. In particular, we give a convenient characterisation of all constitutive laws for which the evolution equations are symmetric hyperbolic. The latter property is sufficient, but not necessary, for well-posedness of the initial-value problem. By way of example, we illustrate our results with the constitutive laws of biisotropic media and of Born-Infeld theory.

description: In questo lavoro di diploma ci si è concentrati sulla tematica migratoria e contemporaneamente sull’apprendimento cooperativo, modalità didattica caratterizzata dal lavoro in piccoli gruppi eterogenei, in cui essenziali sono la collaborazione tra i discenti e l’acquisizione del sapere tra pari. Parallelamente, questo lavoro mirava a sviluppare il pensiero riflessivo e critico, una delle competenze trasversali citate nel Piano di studio della scuola dell’obbligo ticinese. L’interpretazione dei dati raccolti grazie al questionario d’entrata, al lavoro a gruppi, alla verifica sommativa finale ha mostrato come l’apprendimento cooperativo abbia, da una parte, permesso agli allievi di apprendere una tematica complessa come quella migratoria, e contemporaneamente abbia consentito ai discenti di confrontarsi con i coetanei ed avanzare riflessioni sulla tematica, sviluppando il loro pensiero riflessivo e critico.

description: We report model calculations of the time-dependent internal energy and entropy for a single quasi-free massive quantum particle at a constant temperature. We show that the whole process started from a fully coherent quantum state to thermodynamic equilibrium can be understood, based on statistics of diffracted matter waves. As a result of thermal interaction between the particle and its surroundings, the motion of the particle shows new feature.

A distortion of very--high--redshift galaxy number counts by gravitational lensing

description: The observed number counts of high-redshift galaxy candidates have been used to build up a statistical description of star-forming activity at redshift z >~ 7, when galaxies reionized the Universe. Standard models predict that a high incidence of gravitational lensing will probably distort measurements of flux and number of these earliest galaxies. The raw probability of this happening has been estimated to be ~ 0.5 percent, but can be larger owing to observational biases. Here we report that gravitational lensing is likely to dominate the observed properties of galaxies with redshifts of z >~ 12, when the instrumental limiting magnitude is expected to be brighter than the characteristic magnitude of the galaxy sample. The number counts could be modified by an order of magnitude, with most galaxies being part of multiply imaged systems, located less than 1 arcsec from brighter foreground galaxies at z ~ 2. This lens-induced association of high-redshift and foreground galaxies has perhaps already been observed among a sample of galaxy candidates identified at z ~ 10.6. Future surveys will need to be designed to account for a significant gravitational lensing bias in high-redshift galaxy samples.

description: We derive new existence results for tight contact structures on certain 3-manifolds which can be presented as surgery along specific knots in S^3. Indeed, we extend our earlier results on knots with maximal Thurston-Bennequin number being equal to 2g-1 to knots for which the maximal self-linking number satisfies the same equality. In the argument (using contact surgery) we define an invariant for transverse knots in contact 3-manifolds under the assumption that either the knot is null-homologous or the 3-manifold has no S^1xS^2-factor in its prime decomposition, and we study its properties using the Ozsvath-Szabo contact invariant.

description: We studied the formation of optical nonlinearity and the generation of the second harmonic signal in glasses irradiated with an electron beam. The dependences of the second-harmonic signal on the electron energy and the density of the transmitted charge are determined. An experimental technique for observing the dynamics of the relaxation of the second-harmonic signal at an elevated temperature is proposed. The temperature relaxation of the second-harmonic signal formed in glasses under irradiation with an electron beam has been studied.
Jet launching and field advection in quasi-Keplerian discs

description: The fact that self-confined jets are observed around black holes, neutron stars and young forming stars points to a jet launching mechanism independent of the nature of the central object, namely the surrounding accretion disc. The properties of Jet Emitting Discs (JEDs) are briefly reviewed. It is argued that, within an alpha prescription for the turbulence (anomalous viscosity and diffusivity), the steady-state problem has been solved. Conditions for launching jets are very stringent and require a large scale magnetic field $B_z$ close to equipartition with the total (gas and radiation) pressure. The total power feeding the jets decreases with the disc thickness: fat ADAF-like structures with $h\sim r$ cannot drive super-Alfvénic jets. However, there exist also hot, optically thin JED solutions that would be observationally very similar to ADAFs. Finally, it is argued that variations in the large scale magnetic $B_z$ field is the second parameter required to explain hysteresis cycles seen in LMXBs (the first one would be $\dot M_a$).

description: Facendo riferimento in particolare alle teorie di Gardner, sono state osservate e analizzate le diverse tipologie di intelligenza e i loro legami con la riuscita scolastica in una pluriclasse elementare. A tale scopo, sono stati proposti alla classe e ai genitori due questionari per conoscere atteggiamenti e comportamenti dei bambini in modo da poter definire il profilo delle intelligenze di ogni allievo. È stato in seguito proposto un intervento basato su attività a postazioni incentrate su un’intelligenza specifica. I bambini hanno potuto attivare le sette intelligenze durante otto lezioni, tramite esercizi e giochi inerenti al contesto scolastico. Le osservazioni e le preferenze finali dei bambini sulle attività proposte sono state confrontate con i dati iniziali sulle intelligenze preferenziali e le caratteristiche dei singoli. Il tutto è stato messo in relazione con la riuscita scolastica osservata dalla docente. I risultati emersi sono stati un miglioramento di abilità trasversali e scolastiche in nove bambini su tredici. È interessante osservare le relazioni fra intelligenze multiple, stili cognitivi e consapevolezza. In conclusione, l’intervento è stato stimolante per i bambini e ha valorizzato gli allievi che sono maggiormente facilitati ad apprendere attraverso le intelligenze che solitamente non si attivano a scuola.

description: We systematically study black holes in the Horava-Lifshitz (HL) theory by following the kinematic approach, in which a horizon is defined as the surface at which massless test particles are infinitely redshifted. Because of the nonrelativistic dispersion relations, the speed of light is unlimited, and test particles do not follow geodesics. As a result, there are significant differences in causal structures and black holes between general relativity (GR) and the HL theory. In particular, the horizon radii generically depend on the energies of test particles. Applying them to the spherical static vacuum solutions found recently in the nonrelativistic general covariant theory of gravity, we find that, for test particles with sufficiently high energy, the radius of the horizon can be made as small as desired, although the singularities can be seen in principle only by observers with infinitely high energy. In these studies, we pay particular attention to the global structure of the solutions, and find that, because of the foliation-preserving-diffeomorphism symmetry, ${Diff}(M,{\cal{F}})$, they are quite different from the corresponding ones given in GR, even though the solutions are the same. In particular, the ${Diff}(M,{\cal{F}})$ does not allow Penrose diagrams. Among the vacuum solutions, some give rise to the structure of the Einstein-Rosen bridge, in which two asymptotically flat regions are connected by a throat with a finite non-zero radius. We also study slowly rotating solutions in such a setup, and obtain all the solutions characterized by an arbitrary function $A_{0}(r)$. The case $A_{0} = 0$ reduces to the slowly rotating Kerr solution obtained in GR.

description: Parkinson’s disease (PD) is a debilitating neurodegenerative disorder characterized by motor dysfunction and loss of dopamine neurons in the substantia nigra (SN). Increasing recognition of non-motor symptoms, many arising before clinical diagnosis and neuron death, has highlighted the involvement of other neurotransmitter systems in early disease processes. Mutations in LRRK2 present the most common cause of familial PD, and alter the function of the LRRK2 protein. Recent findings revealed that LRRK2 acts at synapses in multiple cell types, and may also be implicated in idiopathic PD. Investigating LRRK2’s role in non-dopaminergic neurotransmission may help identify early synaptic phenotypes and their contribution to PD pathophysiology, particularly within the basal ganglia. Perturbed neurotransmission converges on GABAergic spiny projection neurons (SPNs) in the striatum, which receive cortical and thalamic glutamatergic inputs, are modulated by dopamine from the SN, and form the gate to the basal ganglia. We examined the impact of altered excitatory input on SPN development and plasticity, by pharmacologically manipulating glutamatergic activity in corticostriatal cocultures from non-transgenic mice. We found that chronic action potential blockade reduced SPN dendritic spine density while increasing filopodia density, and altered presynaptic protein expression. While glycine stimulation in low magnesium was sufficient to drive spine density and AMPA receptor changes characteristic of long-term potentiation, mGluR activation by DHPG did not alter measures indicative of long-term depression. Thus, glutamatergic activity drives some bi-directional structural plasticity in SPNs, even in the absence of dopamine. Next, we examined how the most common LRRK2 mutation, the G2019S substitution, altered glutamatergic synapses. We used wild-type and LRRK2-G2019S knock-in (GKI) mice to compare synaptic transmission by electrophysiological recordings, and synaptic protein expression by immunocytochemistry. We found increased spontaneous glutamate release in cultured cortical neurons from GKI mice, and a synaptic reorganization in corticostriatal cocultures. Separately examining cortical and thalamic activity by optogenetic stimulation revealed altered evoked release in both input pathways in striatal slices from young GKI mice, with no changes in postsynaptic measures. Lastly, acute LRRK2 kinase inhibition restored neurotransmission in GKI slices; this confirms the pathogenic role of increased kinase activity and suggests its potential as a therapeutic target.
