description: Stellar rotation is a fundamental observable that drives different aspects of stellar and planetary evolution. In this work, we present an unprecedented manifold analysis of 160 B-type stars with light curves collected by the TESS space mission using three different procedures (Fast Fourier Transform, Lomb-Scargle, and wavelet techniques), accompanied by rigorous visual inspection in the search for rotation periodicities. This effort provides rotational periodicities for 6 new TESS B-type stars and confirmed periodicities for 22 targets with rotation periods previously listed in the literature. For other 61 stars, already classified as possible rotational variables, we identify noisy, pulsational, binarity, or ambiguous variability behavior rather than rotation signatures. The total sample of 28 potential rotators shows an overlap of different classes of rotational variables, composed of $α^2$ Canum Venaticorum, rotating ellipsoidal and SX Arietis stars. The combination of the three techniques applied in our analysis offers a solid path to overcome the challenges in the discrimination of rotation from other variabilities in stellar light curves, such as pulsation, binarity or other effects that have no physical meaning. Finally, the rotational periodicities reported in the present study may represent important constraints for improving stellar evolution models with rotation, as well as asteroseismic studies of hot stars.

description: We show, using a model coupling mass transport and liquid theory calculations for a charge-stabilized colloidal dispersion, that diffusion significantly limits measurement times of its Equation Of State (EOS), osmotic pressure vs composition, using the osmotic compression technique. Following this result, we present a microfluidic chip allowing one to measure the entire EOS of a charged dispersion at the nanoliter scale in a few hours. We also show that time-resolved analyses of relaxation to equilibrium in this microfluidic experiment lead to direct estimates of the collective diffusion coefficient of the dispersion in Donnan equilibrium with a salt reservoir.

description: We present result of processing of data of ground-space VLBI experiment titled W068. Particularly, one part of data of that observational session is successfully processed. These data were obtained on 2000 March 17 between 9:00 UT and 10:30 UT. 10 antennas of American interferometer VLBA (Very Long Baseline Array) and Japan satellite VSOP (VLBI Space Observatory Programme) were involved into this experiment. Moreover, 27 antennae of VLA (Very Large Array)} were used as an additional ground antenna. Data were transferred from archive of the NRAO (National Radio Astronomy Observatory, USA)and processed with the software titled 'Astro Space Locator' (ASL for Windows). The main result of this processing is the image of the quasar titled 3C273 with high resolution and high accuracy. Using this image, we make some conclusions about the radio structure of jet of this object. Our result is not in conflict with other results of processing of the Space VLBI data for 3C273 published earlier with many authors. We could add some new aspects into that results. The reconstructed images of 3C273 for 6 centimeter wavelength range and values of some parameters of this source are presented.

description: To provide privacy-aware software systems, it is crucial to consider privacy from the very beginning of the development. However, developers do not have the expertise and the knowledge required to embed the legal and social requirements for data protection into software systems. Objective: We present an approach to decrease privacy risks during agile software development by automatically detecting privacy-related information in the context of user story requirements, a prominent notation in agile Requirement Engineering (RE). Methods: The proposed approach combines Natural Language Processing (NLP) and linguistic resources with deep learning algorithms to identify privacy aspects into User Stories. NLP technologies are used to extract information regarding the semantic and syntactic structure of the text. This information is then processed by a pre-trained convolutional neural network, which paved the way for the implementation of a Transfer Learning technique. We evaluate the proposed approach by performing an empirical study with a dataset of 1680 user stories. Results: The experimental results show that deep learning algorithms allow to obtain better predictions than those achieved with conventional (shallow) machine learning methods. Moreover, the application of Transfer Learning allows to considerably improve the accuracy of the predictions, ca. 10%. Conclusions: Our study contributes to encourage software engineering researchers in considering the opportunities to automate privacy detection in the early phase of design, by also exploiting transfer learning models.

description: We re-examine the question of measuring the weak phase gamma in B -> K pi pi decays. To this end, we express all B -> K pi pi amplitudes in terms of diagrams. We show that, as in B -> K pi, there exist relations between certain tree and electroweak-penguin diagrams. The imposition of these relations allows the extraction of gamma from measurements of the B -> K pi pi observables. We estimate the theoretical error in this method to be O(5%).

description: We study an experimental setup in which a quantum probe, provided by a quasi-monomode guided atom laser, interacts with a static localized attractive potential whose characteristic parameters are tunable. In this system, classical mechanics predicts a transition from a regular to a chaotic behavior as a result of the coupling between the longitudinal and transverse degrees of freedom. Our experimental results display a clear signature of this transition. On the basis of extensive numerical simulations, we discuss the quantum versus classical physics predictions in this context. This system opens new possibilities for investigating quantum scattering, provides a new testing ground for classical and quantum chaos and enables to revisit the quantum-classical correspondence.
The spatiality of occupation in a migration context : exploring French-speaking immigrants’ occupational engagement in Francophone community sites in Metro Vancouver
Creators: name: Delaisse, Anne-Cécile
Publisher: name: University of British Columbia
Year: 2020

description: International migration is receiving increasing attention in occupational science, especially the interactions between the environments, the occupations and the identities of voluntary and forced migrants. The perspective of viewing these as related, but largely independent of one another can conflict with those in the discipline who have been advocating a transactional approach for more than a decade. Moreover, little remains known about the production of space occurring through occupational engagement and the spatiality of occupation in a migration context. This critical ethnography explores the occupations of French-speaking voluntary and forced migrants (immigrants) in Metro Vancouver, in a Francophone minority context. Taking a transactional approach to the study of occupation and drawing from Lefebvre’s theory of the production of space, this research examines the meaning and the production of Francophone spaces in French-speaking immigrants’ daily lives. Attention was paid to diverse intersecting identity markers in immigrants’ experiences and in the production of Francophone spaces. More specifically, partnerships were established with three Francophone community sites and I collected data through in-depth and go-along interviews with fifteen immigrants, and three key informant interviews. Combining transactionalism and Lefebvre’s theory of the production of space allowed me to analyse the production of formal Francophone community spaces through (1) their conception by their leadership, (2) immigrants’ perceptions and understandings and (3) the lived experiences of occupational engagement in these spaces. I paid particular attention to the production of these spaces in regard to the diversity stemming from international migration. While occupational engagement in French was fluid over spaces, formal Francophone spaces represented stable French-speaking landmarks in the Anglo-dominant context of Metro Vancouver. The production of stable spaces, durable over time required a conception by their leaderships and shared perception by the participants. However, occupation was the omnipresent element in both formal and informal spaces, and while it was dominated by the two other components, conceived and perceived space in formal Francophone spaces, it was ultimately shaping these spaces.

description: We isolate a new class of ultrafilters on N, called "quasi-selective" because they are intermediate between selective ultrafilters and P-points. (Under the Continuum Hypothesis these three classes are distinct.) The existence of quasi-selective ultrafilters is equivalent to the existence of "asymptotic numerosities" for all sets of tuples of natural numbers. Such numerosities are hypernatural numbers that generalize finite cardinalities to countable point sets. Most notably, they maintain the structure of ordered semiring, and, in a precise sense, they allow for a natural extension of asymptotic density to all sequences of tuples of natural numbers.

Year: 2023

description: Il "Lesson Study" è un dispositivo di ricerca e di micro-formazione dei docenti originario del Giappone che, grazie ad opportune trasposizioni culturali, si è diffuso in molti paesi occidentali. Il cuore del processo si basa sulla collaborazione e il confronto reciproco tra i docenti, attraverso una ciclica co-progettazione, osservazione e riflessione sulle lezioni. Lo scopo di questa tesi è stato quello di analizzare come questo dispositivo potesse essere adattato e utilizzato nel contesto della scuola dell'obbligo ticinese e nell’ambito del problem solving geometrico. Un gruppo composto da tre docenti di matematica e una docente-ricercatrice ha svolto un'attività sperimentale in tre classi di II media, coinvolgendo 55 allievi, durante le ore di laboratorio didattico. Dopo una lezione pilota, in tutti i cicli successivi, si è osservato un progressivo miglioramento della qualità del processo di insegnamento-apprendimento. Infatti, il lavoro di co-progettazione e debriefing ha portato all’affinamento degli obiettivi di apprendimento, dei materiali e dei feedback formativi da offrire agli allievi. Inoltre, il dispositivo si è adattato in modo soddisfacente al contesto ticinese, con le adeguate modifiche nella fase precedente e successiva alla lezione di ricerca, beneficiando dell’organizzazione scolastica del laboratorio. Infine, i partecipanti ne hanno confermato l'efficacia in termini di crescita professionale, collaborazione, consapevolezza critica e competenza didattica. Relatrice: Rossana Falcade Pincolini.

Emergence of Anchored Flux Tubes Through the Convection Zone

description: We model the evolution of buoyant magnetic flux tubes in the Sun's convection zone. A flux tube is assumed to lie initially near the top of the stably stratified radiative core below the convection zone, but a segment of it is perturbed into the convection zone by gradual heating and convective overshoot motions. The ends ("footpoints") of the segment remain anchored at the base of the convection zone, and if the segment is sufficiently long, it may be buoyantly unstable, rising through the convection zone in a short time. The length of the flux tube determines the ratio of buoyancy to magnetic tension: short loops of flux are arrested before reaching the top of the convection zone, while longer loops emerge to erupt through the photosphere. Using Spruit's convection zone model, we compute the minimum footpoint separation $L_c$ required for erupting flux tubes. We explore the dependence of $L_c$ on the initial thermal state of the perturbed flux tube segment and on its initial magnetic field strength. Following an investigation of thermal diffusion time scales and the dynamic rise times of unstable flux tube segments, we conclude that the most likely origin for magnetic flux which erupts to the surface is from short length scale perturbations ($L < L_c$) which are initially stable, but which are subsequently destabilized either by diffusion of heat into the tube or by stretching of the anchor points until $L$ just exceeds $L_c$. In either case, the separation of the anchor points of the emergent tube should lie between the critical distance for a tube in mechanical equilibrium and one in thermal equilibrium. Finally, after comparing the dispersion of dynamic rise times with the much shorter observed active region formation time scales, we conclude that active regions form from the emergence of a single flux tube segment.

description: We consider systems of ordinary differential equations with known first integrals. The notion of a discrete tangent space is introduced as the orthogonal complement of an arbitrary set of discrete gradients. Integrators which exactly conserve all the first integrals simultaneously are then defined. In both cases we start from an arbitrary method of a prescribed order (say, a Runge-Kutta scheme) and modify it using two approaches: one based on projection and one based one local coordinates. The methods are tested on the Kepler problem.

description: Using an analytical model, we study the evolution of subhalo, including its mass, angular momentum and merging time-scale. This model considers the dominant processes governing subhalo evolution, such as dynamical friction, tidal stripping and tidal heating. We find that in order to best match the evolution of angular momentum measured from N-body simulation, mass stripping by tidal force should become inefficient after subhalo has experienced a few passages of pericenter. It is also found that the often used Coulomb logarithm $\ln M/m$ has to be revised to best fit the merging time-scales from simulation. Combining the analytical model with the Extended Press-Schechter (EPS) based merger trees, we study the subhalo mass function, and their spatial distribution in a Milky-Way (MW) type halo. By tuning the tidal stripping efficiency, we can gain a better match to the subhalo mass function from simulation. The predicted distribution of subhaloes is found to agree with the distribution of MW satellites, but is more concentrated than the simulation results. The radial distribution of subhaloes depends weakly on subhaloes mass at both present day and the time of accretion, but strongly on the accretion time. Using the improved model, we measure the second moment of the subhalo occupation distribution, and it agrees well with the results of Kravtsov et al. (2004a) and Zheng et al. (2005).

description: In this study, a typical Chinese medicine injection (Mai-luo-ning, MLN) was chosen to study the transformation possibility of its by-products (polysaccharides). What’s more, the basic properties of polysaccharides were also detected and its immunoprotect and anti-inflammatory activity were both proved in vivo and in vitro. The experiment determined that MLN-1 significantly increased the level of anti-inflammatory-related factors and the number of lymphocytes. Acute oral toxicity study established that MLN-1 has a non-toxic effect. The present work successfully showed that MLN-1 has the potential to be developed as a food additive.
Coherent periodic activity in excitatory Erdos-Renyi neural networks:The role of network connectivity

description: We consider an excitatory random network of leaky integrate-and-fire pulse coupled neurons. The neurons are connected as in a directed Erdös-Renyi graph with average connectivity $$ scaling as a power law with the number of neurons in the network. The scaling is controlled by a parameter $γ$, which allows to pass from massively connected to sparse networks and therefore to modify the topology of the system. At a macroscopic level we observe two distinct dynamical phases: an Asynchronous State (AS) corresponding to a desynchronized dynamics of the neurons and a Partial Synchronization (PS) regime associated with a coherent periodic activity of the network. At low connectivity the system is in an AS, while PS emerges above a certain critical average connectivity $_c$. For sufficiently large networks, $_c$ saturates to a constant value suggesting that a minimal average connectivity is sufficient to observe coherent activity in systems of any size irrespectively of the kind of considered network: sparse or massively connected. However, this value depends on the nature of the synapses: reliable or unreliable. For unreliable synapses the critical value required to observe the onset of macroscopic behaviors is noticeably smaller than for reliable synaptic transmission. Due to the disorder present in the system, for finite number of neurons we have inhomogeneities in the neuronal behaviors, inducing a weak form of chaos, which vanishes in the thermodynamic limit. In such a limit the disordered systems exhibit regular (non chaotic) dynamics and their properties correspond to that of a homogeneous fully connected network for any $γ$-value. Apart for the peculiar exception of sparse networks, which remain intrinsically inhomogeneous at any system size.

description: Al giorno d’oggi sono ancora milioni i bambini nel mondo che a cause delle disuguaglianze sociali e di altre forme di deprivazione crescono in ambienti non favorevoli al loro sviluppo fisico e cerebrale. Le disuguaglianze sociali si ramificano in varie categorie caratterizzate dall’aspetto comune dell’inuguaglianza nella distribuzione di condizioni e opportunità, di cui l’accesso all’istruzione fa parte. L’istruzione rappresenta uno dei canali maggiormente incisivi attraverso il quale costruire le basi per un buon sviluppo del cervello. Tuttavia, l’istruzione non è ancora garantita in modo equo nel mondo; ed essendo l’infanzia un periodo evolutivo critico per la formazione delle connessioni neurali e delle aree del cervello, le condizioni ambientali nel quale si sviluppa risultano cruciali. Nel presente lavoro si analizza l’impatto delle disuguaglianze sociali e della deprivazione sullo sviluppo del cervello del bambino, indagando come esso viene influenzato dalle circostanze esterne e dalle esperienze vissute durante l’infanzia. Tale ricerca riporta in conclusione delle ipotesi di lavoro per far fronte alla problematica sul fronte economico e educativo con proposte derivanti da studi realizzati in campo neuroscientifico e con un esempio di un’associazione che si è attivata sul campo, costruendo una scuola in una zona di necessità nella regione costiera del Kenya; nella quale ho avuto l’occasione di vivere un’esperienza di mobilità di due mesi.

description: 5D UED is not automatically minimally flavor violating. This is due to flavor asymmetric counter-terms required on the branes. Additionally, there are likely to be higher dimensional operators which directly contribute to flavor observables. We document a mostly unsuccessful attempt at utilizing localization in a flat extra dimension to resolve these flavor constraints while maintaining KK-parity as a good quantum number. It is unsuccessful insofar as we seem to be forced to add brane operators in such a way as to precisely mimic the effects of a double throat warped extra dimension. In the course of our efforts, we encounter and present solutions to a problem common to many extra dimensional models in which fields are "doubly localized:" ultra-light modes. Under scrutiny, this issue seems tied to an intrinsic tension between maintaining Kaluza-Klein parity and resolving mass hierarchies via localization.

description: In this paper, we present a new mathematical approach or solving procedure for analysis of the Sundman inequality (for estimating the moment of inertia of the Solar system configuration) with the help of Lagrange-Jacobi relation, under additional assumption of decreasing of the total angular momentum close to the zero absolute magnitude in the final state of Solar system in a future. By assuming such the final state for Solar system, we have estimated the mean-size of Solar system R via analysis of the Sundman inequality. So, to answer the question "Does the ninth planet exist in Solar system?", one should meet the two mandatory criteria for such the ninth planet, first is that it should have the negligible magnitude of inclination of its orbit with respect to the invariable plane. The second condition is that the orbit of the ninth planet should be located within the estimation for the mean-size of Solar system R.

description: An operad (this paper deals with non-symmetric operads)may be conceived as a partial algebra with a family of insertion operations, Gerstenhaber's circle-i products, which satisfy two kinds of associativity, one of them involving commutativity. A Cat-operad is an operad enriched over the category Cat of small categories, as a 2-category with small hom-categories is a category enriched over Cat. The notion of weak Cat-operad is to the notion of Cat-operad what the notion of bicategory is to the notion of 2-category. The equations of operads like associativity of insertions are replaced by isomorphisms in a category. The goal of this paper is to formulate conditions concerning these isomorphisms that ensure coherence, in the sense that all diagrams of canonical arrows commute. This is the sense in which the notions of monoidal category and bicategory are coherent. The coherence proof in the paper is much simplified by indexing the insertion operations in a context-independent way, and not in the usual manner. This proof, which is in the style of term rewriting, involves an argument with normal forms that generalizes what is established with the completeness proof for the standard presentation of symmetric groups. This generalization may be of an independent interest, and related to matters other than those studied in this paper. Some of the coherence conditions for weak Cat-operads lead to the hemiassociahedron, which is a polyhedron related to, but different from, the three-dimensional associahedron and permutohedron.

description: We report spectropolarimetry of 30 radio-selected broad absorption line (BAL) quasars with the Keck Observatory, 25 from the sample of Becker et al. (2000). Both high and low-ionization BAL quasars are represented, with redshifts ranging from 0.5 to 2.5. The spectropolarimetric properties of radio-selected BAL quasars are very similar to those of radio-quiet BAL quasars: a sizeable fraction (20%) show large continuum polarization (2-10%) usually rising toward short wavelengths, emission lines are typically less polarized than the continuum, and absorption line troughs often show large polarization jumps. There are no significant correlations between polarization properties and radio properties, including those indicative of system orientation, suggesting that BAL quasars are not simply normal quasars seen from an edge-on perspective.
Natural non-protein amino acids in diverse ecosystems
Creators: name: Bishop, Stephanie L.
Publisher: name: University of British Columbia

description: Cyanobacteria form large blooms and produce toxins which bioaccumulate in common foods. Exposure to cyanobacterial toxins, including the non-protein amino acid β-N-methylamino-L-alanine (BMAA), is linked to increased risk of neurodegenerative disease. Three isomers of BMAA: 2,4-diaminobutyric acid (DAB), N-(2-aminoethyl)glycine (AEG) and β-aminomethyl-L-alanine (BAMA) are also routinely measured. My overall objective was to develop research methods and approaches for studies of non-protein amino acids in diverse ecosystems. My specific objectives were: (a) to systematically review analytical methods for BMAA; (b) to develop a method to isolate a cyanobacterial protein for use in a field-deployable BMAA biosensor; (c) to quantify BMAA and its isomers in cyanobacteria from Lake Winnipeg and Pavilion Lake; (e) to determine the persistence and quantity of BMAA in the traditional cyanobacterial foods of the indigenous peoples of Peru and Chile; and (f) to determine whether these traditional cyanobacterial foods provide nutritional benefits. The largest discrepancy between BMAA analytical methods arose from the analysis of cyanobacterial matrices suggesting that methods must be fully validated. I also developed a BMAA-bound affinity chromatography resin to isolate BMAA-binding cyanobacterial proteins that can be used in a field-deployable biosensor. In Lake Winnipeg, BMAA and BAMA were found in highest concentration in the north basin, the lowest nitrogen region of the lake while AEG and DAB were found in the more nitrogen-rich zone. Analysis of microbialites collected from Pavilion Lake in British Columbia revealed that AEG, DAB and BAMA were highest in the shallow microbialites while BMAA was highest in deeper collections. In studies of non-protein amino acids, minerals, proteins and other nutrients in traditional cyanobacterial foods from Peru and Chile, I found BMAA and AEG in lower concentration than DAB and BAMA in cyanobacterial foods. Environmental toxins including lead, mercury and arsenic were also detected in traditional Andean foods. Overall, my studies show that cyanobacteria produce BMAA and its isomers in diverse ecosystems and food webs. A better understanding of these non-protein amino acids will provide insight into environmental factors that have shaped the evolution of life on early earth and recommendations for water management strategies to mitigate risks to human health.

description: The bound of the information transmission rate of direct current biased optical orthogonal frequency division multiplexing (DCO-OFDM) for visible light communication (VLC) with finite-alphabet inputs is yet unknown, where the corresponding spectral efficiency (SE) and energy efficiency (EE) stems out as the open research problems. In this paper, we derive the exact achievable rate of {the} DCO-OFDM system with finite-alphabet inputs for the first time. Furthermore, we investigate SE maximization problems of {the} DCO-OFDM system subject to both electrical and optical power constraints. By exploiting the relationship between the mutual information and the minimum mean-squared error, we propose a multi-level mercury-water-filling power allocation scheme to achieve the maximum SE. Moreover, the EE maximization problems of {the} DCO-OFDM system are studied, and the Dinkelbach-type power allocation scheme is developed for the maximum EE. Numerical results verify the effectiveness of the proposed theories and power allocation schemes.
