The inertia operator and Hall algebra of algebraic stacks
Creators: name: Ronagh, Pooya
Publisher: name: University of British Columbia
Year: 2016

description: We view the inertia construction of algebraic stacks as an operator on the Grothendieck groups of various categories of algebraic stacks. We are interested in showing that the inertia operator is (locally finite and) diagonalizable over for instance the field of rational functions of the motivic class of the affine line q = [A¹]. This is proved for the Grothendieck group of Deligne-Mumford stacks and the category of quasi-split Artin stacks. Motivated by the quasi-splitness condition we then develop a theory of linear algebraic stacks and algebroids, and define a space of stack functions over a linear algebraic stack. We prove diagonalization of the semisimple inertia for the space of stack functions. A different family of operators is then defined that are closely related to the semisimple inertia. These operators are diagonalizable on the Grothendieck ring itself (i.e. without inverting polynomials in q) and their corresponding eigenvalue decompositions are used to define a graded structure on the Grothendieck ring. We then define the structure of a Hall algebra on the space of stack functions. The commutative and non-commutative products of the Hall algebra respect the graded structure defined above. Moreover, the two multiplications coincide on the associated graded algebra. This result provides a geometric way of defining a Lie subalgebra of virtually indecomposables. Finally, for any algebroid, an ε-element is defined and shown to be contained in the space of virtually indecomposables. This is a new approach to the theory of generalized Donaldson-Thomas invariants.
Filosofia interculturale. Piccola rapsodia concettuale a tre voci

description: Tre studiosi di filosofia interculturale espongono – molto sinteticamente – le loro posizioni su alcuni snodi problematici del loro oggetto di ricerca. Cacciatore si concentra sulla relazione teorica, assai fruttuosa, fra lo storicismo critico-problematico, antiontologico e antimetafisico, della Scuola napoletana e i temi connessi all’interculturalità. D’Anna ritrova in Aristotele – discusso anche attraverso Pietro Piovani e Raul Fornet-Betancourt – un concetto di universale che, distinto da quello di assoluto, è inclusivo della molteplicità e dunque funzionale alla riflessione interculturale. Diana – seguendo un percorso che contamina letteratura e filosofia – mette in luce il carattere storico, plurimo e relazionale dell’identità individuale e chiarisce il senso del cogito autobiografico.Three intercultural philosophy academics expose – very briefly – their positions about some problematic joints of their research object. Cacciatore focuses on the theoretical relationship, very fruitful, between the critical-problematic, anti-ontological and metaphysical historicism of the Neapolitan school, and on the issues related to interculturalism. D'Anna finds in Aristotle – also discussed by way of Pietro Piovani and Raul Fornet-Betancourt – a concept of “universal” that, separated from the idea of “absolute”, is inclusive of diversity and therefore functional to intercultural reflection. Diana – following a pattern that contaminates literature and philosophy – highlights the historical, relational and plural disposition of the individual identity and clarifies the meaning of the autobiographical cogito.

description: The two-component liquid model reproduces the basic properties of the quark-gluon plasma as observed in heavy-ion collisions. The key dynamic element of the model is the existence of a light scalar. We argue that existence of such a scalar is a generic feature of stringy models of quantum chromodynamics. The lattice data provide evidence for a condensed, three-dimensional scalar field as well. We outline a possible crucial check of the model on the lattice.
HISTORICAL AND NOMENCLATURAL REMARKS ON SOME MEGATOOTHED SHARK TEETH (ELASMOBRANCHII, OTODONTIDAE) FROM THE CENOZOIC OF NEW JERSEY (U.S.A.)

description: . In the second issue of Samuel Morton’s “Synopsis of the Organic Remains of the Cretaceous Group of the United States” published in June 1835, several otodontid shark teeth from Cenozoic formations of New Jersey are named with authorship of Louis Agassiz and meet the conditions of availability of the International Code of Zoological Nomenclatural. It has gone largely unnoticed that some of these names were introduced in this work before their publication in Agassiz’s masterpiece “Recherches sur les poissons fossiles”. The specimens presented by Morton were kept in the John Price Wetherill (1794-1853) collection that found its way into the paleontological collection of the Academy of Natural Sciences of Drexel University, Philadelphia, where most of them have been rediscovered. These teeth are part of the type series upon which Agassiz introduced Lamna obliqua Agassiz in Morton, 1835, Lamna lanceolata Agassiz in Morton, 1835, Carcharias lanceolatus Agassiz in Morton, 1835, Carcharias megalotis Agassiz, 1835 and Carcharias polygurus Agassiz in Morton, 1835, all of these species being referred to the genus Otodus in the present work. In order to secure the nomenclatural stability of the Otodontidae, it is established that Otodus lanceolatus is a junior synonym of Otodus obliquus, that “Carcharias” lanceolatus belongs to the genus Otodus Agassiz, 1838 and is invalid as a junior secondary homonym of Otodus lanceolatus, that Otodus megalotis is a junior synonym of Otodus auriculatus (Blainville, 1818), and that Otodus polygurus (Otodus polygyrus being an incorrect subsequent spelling) is a junior synonym of Otodus megalodon (Agassiz, 1835). Furthermore, it is shown that the date of publication of Otodus obliquus (Agassiz in Morton, 1835) is 1835 and not 1838 as previously thought.

A review of ptychographic techniques for ultrashort pulse measurement
Creators: name: Kane, Daniel J
name: Vakhtin, Andrei B.
Publisher: name: arXiv
Year: 2023
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: The measurement of optical ultrafast laser pulses is done indirectly because the required bandwidth to measure these pulses exceeds the bandwidth of current electronics. As a result, this measurement problem is often posed as a 1-D phase retrieval problem, which is fraught with ambiguities. The phase retrieval method known as ptychography solves this problem by making it possible to measure ultrafast pulses in either the time domain or the frequency domain. One well known algorithm is the principal components generalized projections algorithm (PCGPA) for extracting pulses from Frequency-Resolved Optical Gating (FROG) measurements. Here, we discuss the development of the PCPGA and introduce new developments including an operator formalism that allows for the convenient addition of external constraints and the development of more robust algorithms. A close cousin, the ptychographic iterative engine will also be covered and compared to the PCGPA. Additional developments using other algorithmic strategies will also be discussed along with new developments combining optics and high-speed electronics to achieve megahertz measurement rates.

Gehören Menschenrechte und Menschenwürde zusammen?

Subjects: Human dignity; human rights; Kant’s philosophy; Martha Nussbaum; human integrity

description: The concept of human dignity seems to be closely connected to the idea of human rights. But whereas human rights are at least from an institutional point of view well established, the concept of human dignity is often seen  as either arbitrary and superfluous or fundamen-talistic. The paper shows that human rights and human dignity had different histories for a long time but are nowadays intrinsically connected. The concept of human dignity implies a certain core of human rights and offers the chance to understand that there is not one overall  view of human rights for all times and places, but that human rights discourse always has to be open to modifications according to the conditions of application. After first mentions in Cicero and Seneca, more diversified uses by Aquinas and Pico della Mirandola, the talk of human dignity finds its current meaning in Kant’s philosophy, often connected to the formula of persons as ends in themselves.  This seems to be one of the systematic connections to the tradition of human rights which has its roots in the semantic shift of the word ius in 11th and 12th century from an objective order to claims of different kinds. This kind of argument is used in different contexts throughout the following centuries and transformed in 16thand 17th century into claims of citizen’s rights and human rights. Another connection between the two concepts is given by Martha Nussbaum’s capability approach which is not restricted to human reason. The criticisms against the two conceptions are also different, but connected: Human rights are accused to foster individualism and egoism against the community and declared to be an erroneous development of western culture. Human dignity is seen as an indicator of human hubris towards other creature, based on metaphysical assumptions and a part of “slave morals”, contempt by men like Nietzsche. Both criticisms seem not to be adequate. In the end, the concept of human dignity gives an instrument to defend as much as possible of human integrity in situations where human rights are violated, limited or in one or the other way under pressure.

title: Engaging Distance Learners in an Academic Community: Student Hub Live
Creators: name: Foley, Karen
Publisher: name: The Open University
Year: 2022

description: In higher education (HE), studies of effective practice relating to student retention, progression and attainment suggest that student engagement is a major factor in terms of success, and this involves a sense of belonging to a community. Studies have identified initiatives that have proved successful in traditional HE contexts, however ideas of belonging and community are problematic when translated to distance-learning contexts. Many distance-learning students, who are often mature and part-time learners, appear to be successful in their studies without identifying as a student or interacting socially with others, which calls into question the way in which belonging is conceptualised in distance-learning settings. The focus of this research was to identify the value of attending specific, live, online, interactive events at Student Hub Live (SHL) which were designed by the Open University to facilitate academic community and to provide a space outside of the curriculum for students to socialise and perform other aspects of student identity that require interaction with others. Using an ethnographic approach and grounded theory methods, chatlogs of four SHL events were analysed and the emergent themes informed semi-structured interviews which were carried out with six participants, all of whom had attended SHL events. Both sets of findings were combined and further analysed using thematic network maps. The finding was that communities of practice with shared repertoires enabled students to feel a sense of belonging through participating in discussions which created a conducive learning environment to develop skills, share experiences and feel validated. Community and belonging enabled students to deeply apply learning to their studies through sharing the experience and their experiences with others. In this sense, belonging and community matter to distance-learning students but for different reasons than for face-to-face students. The findings are relevant to other distance and face-to-face HE providers who are keen to engage students in virtual extracurricular spaces to support learning and facilitate community.

description: The cavities of SBA mesoporous silica materials can be used as nanoreactors for embedding catalytic species such as nanoparticles, complexes and heteropol- yacids etc. The encapsulated catalysts are renowned as superior catalytic systems regarding their catalytic activity, selectivity and reusability as well as suppressed leaching. An efficient method to improve the encapsulation of these catalysts, is in creating anchors for capturing catalytic species. It has been performed by functionalization of the surface of SBA mesoporous silica materials with various groups including sulfur, phosphorus and amine-based functional groups. The aim of this article is to review the recent advances (2014-2017) in the field of the utility of functionalized SBA for developing encapsulated catalysts. In most cases the reusability of the catalyst and the leaching of the catalytic active species were discussed to disclose the role of functionalized SBA in heterogenizing and suppressing the leaching. Moreover, to show the superiority of these developed encapsulated catalysts, with a couple of examples we compared their catalytic activities with those of the conventional ones.

description: We show that in supersymmetry one can obtain inflationary potentials in the observable sector that are sufficiently flat at sub-Planckian field values. Structure of the supersymmetric scalar potential along a flat direction combined with the existence of higher order terms in an effective field theory expansion allows one to find scales below the effective field theory cut off where two or a higher number of the potential derivatives may vanish. As an explicit example, we demonstrate that inflection point inflation within a broad range of scales O(TeV) << H < 3 x 10^9 GeV can be accommodated within weak scale supersymmetry. The fine tuning of model parameters needed for successful inflation is considerably improved in this scenario.

description: We report on the discovery of 10 additional galaxy clusters detected in the ongoing Swift/BAT all-sky survey. Among the newly BAT-discovered clusters there are: Bullet, Abell 85, Norma, and PKS 0745-19. Norma is the only cluster, among those presented here, which is resolved by BAT. For all the clusters we perform a detailed spectral analysis using XMM-Newton and Swift/BAT data to investigate the presence of a hard (non-thermal) X-ray excess. We find that in most cases the clusters' emission in the 0.3-200keV band can be explained by a multi-temperature thermal model confirming our previous results. For two clusters (Bullet and Abell 3667) we find evidence for the presence of a hard X-ray excess. In the case of the Bullet cluster, our analysis confirms the presence of a non-thermal, power-law like, component with a 20-100 keV flux of 3.4 \times 10-12 erg cm-2 s-1 as detected in previous studies. For Abell 3667 the excess emission can be successfully modeled as a hot component (kT=~13keV). We thus conclude that the hard X-ray emission from galaxy clusters (except the Bullet) has most likely thermal origin.

description: Cobalt substitutions were investigated in Ni0.4Zn0.4Cu0.2Fe2O4 ferrites, initial complex permeability was then measured from 1 MHz to 1 GHz. It appears that cobalt substitution led to a decrease in the permeability and an increase in the \mus\timesfr factor. As well, it gave to the permeability spectrum a sharp resonance character. We also observed a spin reorientation occurring at a temperature depending on the cobalt content. Study of the complex permeability versus temperature highlighted that the most resonant character was obtained at this temperature. This shows that cobalt contribution to second order magnetocrystalline anisotropy plays a leading role at this temperature.

description: The disk masses of four low surface brightness galaxies (LSB) were estimated using marginal gravitational stability criterion and the stellar velocity dispersion data which were taken from Pizzella et al., 2008 [1]. The constructed mass models appear to be close to the models of maximal disk. The results show that the disks of LSB galaxies may be significantly more massive than it is usually accepted from their brightnesses. In this case their surface densities and masses appear to be rather typical for normal spirals. Otherwise, unlike the disks of many spiral galaxies, the LSB disks are dynamically overheated.

description: We analyze low-frequency vibrational modes in a two-dimensional, zero-temperature, quasistatically sheared model glass to identify a population of structural "soft spots" where particle rearrangements are initiated. The population of spots evolves slowly compared to the interval between particle rearrangements and the soft spots are structurally different from the rest of the system. Our results suggest that disordered solids flow via localized rearrangements that tend to occur at soft spots, which are analogous to dislocations in crystalline solids.

description: Recent years brought advancements in using neural networks for representation learning of various language or visual phenomena. New methods freed data scientists from hand-crafting features for common tasks. Similarly, problems that require considering the spatial variable can benefit from pretrained map region representations instead of manually creating feature tables that one needs to prepare to solve a task. However, very few methods for map area representation exist, especially with respect to road network characteristics. In this paper, we propose a method for generating microregions' embeddings with respect to their road infrastructure characteristics. We base our representations on OpenStreetMap road networks in a selection of cities and use the H3 spatial index to allow reproducible and scalable representation learning. We obtained vector representations that detect how similar map hexagons are in the road networks they contain. Additionally, we observe that embeddings yield a latent space with meaningful arithmetic operations. Finally, clustering methods allowed us to draft a high-level typology of obtained representations. We are confident that this contribution will aid data scientists working on infrastructure-related prediction tasks with spatial variables.

Brain connectivity network modeling using fMRI signals
Creators: name: Liu, Aiping
Publisher: name: University of British Columbia
Year: 2016

description: Functional magnetic resonance imaging (fMRI) is one of the most popular non-invasive neuroimaging technologies, which examines human brain at relatively good spatial resolution in both normal and disease states. In addition to the investigation of local neural activity in isolated brain regions, brain connectivity estimated from fMRI has provided a system-level view of brain functions. Despite recent progress on brain connectivity inference, there are still several challenges. Specifically, this thesis focuses on developing novel brain connectivity modeling approaches that can deal with particular challenges of real biomedical applications, including group pattern extraction from a population, false discovery rate control, incorporation of prior knowledge and time-varying brain connectivity network modeling. First, we propose a multi-subject, exploratory brain connectivity modeling approach that allows incorporation of prior knowledge of connectivity and determination of the dominant brain connectivity patterns among a group of subjects. Furthermore, to integrate the genetic information at the population level, a framework for genetically-informed group brain connectivity modeling is developed. We then focus on estimating the time-varying brain connectivity networks. The temporal dynamics of brain connectivity assess the brain in the additional temporal dimension and provide a new perspective to the understanding of brain functions. In this thesis, we develop a sticky weighted time-varying model to investigate the time-dependent brain connectivity networks. As the brain must strike a balance between stability and flexibility, purely assuming that brain connectivity is static or dynamic may be unrealistic. We therefore further propose making joint inference of time-invariant connections and time-varying coupling patterns by employing a multitask learning model. The above proposed methods have been applied to real fMRI data sets, and the disease induced changes on the brain connectivity networks have been observed. The brain connectivity study is able to provide deeper insights into neurological diseases, complementing the traditional symptom-based diagnostic methods. Results reported in this thesis suggest that brain connectivity patterns may serve as potential disease biomarkers in Parkinson's Disease.

description: Electronic sensors play important roles in various applications, such as industry and environmental monitoring, biomedical sample ingredient analysis, wireless networks and so on. However, the sensitivity and robustness of current schemes are often limited by the low quality-factors of resonators and fabrication disorders. Hence, exploring new mechanisms of the electronic sensor with a high-level sensitivity and a strong robustness is of great significance. Here, we propose a new way to design electronic sensors with superior performances based on exotic properties of non-Hermitian topological physics. Owing to the extreme boundary-sensitivity of non-Hermitian topological zero modes, the frequency shift induced by boundary perturbations can show an exponential growth trend with respect to the size of non-Hermitian topolectrical circuit sensors. Moreover, such an exponential growth sensitivity is also robust against disorders of circuit elements. Using designed non-Hermitian topolectrical circuit sensors, we further experimentally verify the ultra-sensitive identification of the distance, rotation angle, and liquid level with the designed capacitive devices. Our proposed non-Hermitian topolectrical circuit sensors can possess a wide range of applications in ultra-sensitive environmental monitoring and show an exciting prospect for nextgeneration sensing technologies.

description: We have demonstrated transport of Be+ ions through a 2D Paul-trap array that incorporates an X-junction, while maintaining the ions near the motional ground-state of the confining potential well. We expand on the first report of the experiment [1], including a detailed discussion of how the transport potentials were calculated. Two main mechanisms that caused motional excitation during transport are explained, along with the methods used to mitigate such excitation. We reduced the motional excitation below the results in Ref. [1] by a factor of approximately 50. The effect of a mu-metal shield on qubit coherence is also reported. Finally, we examined a method for exchanging energy between multiple motional modes on the few-quanta level, which could be useful for cooling motional modes without directly accessing the modes with lasers. These results establish how trapped ions can be transported in a large-scale quantum processor with high fidelity.

description: We study the effect of disc self-gravity on vortex-forming instabilities associated with gaps opened by a Saturn mass planet in a protoplanetary disc. It is shown analytically and confirmed through linear calculations that vortex modes with low azimuthal mode number $,m,$ are stabilised by increasing self-gravity if the basic state is fixed. However, linear calculations show that the combined effect of self-gravity through the background and through the linear response shifts the most unstable vortex mode to higher $m.$ Nonlinear hydrodynamic simulations of planetary gaps show more vortices develop with increasing strength of self-gravity. For sufficiently large disc mass the vortex instability is suppressed and replaced by a new global instability, consistent with analytical expectations. In the nonlinear regime, vortex merging is increasingly delayed as the disc mass increases and multiple vortices may persist until the end of simulations. With self-gravity, the post-merger vortex is localised in azimuth and has similar structure to a Kida-like vortex. This is unlike the case without self-gravity where vortices merge to form a single vortex extended in azimuth. We also performed a series of supplementary simulations of co-orbital Kida-like vortices and found that self-gravity enables such vortices to execute horseshoe turns upon encountering each other. As a result vortex merging is avoided on time-scales where it would occur without self-gravity. Thus we suggest that mutual repulsion of self-gravitating vortices in a rotating flow is responsible for the delayed vortex merging above. The effect of self-gravity on vortex-induced migration is briefly discussed. We found that when self-gravity is included, the vortex-induced type III migration of Lin & Papaloizou (2010) is delayed but the extent of migration is unchanged.

description: We calculate the static Wilson loop from string/gauge correspondence to obtain the $Q\bar Q$ potential in non-relativistic quantum field theory, i.e. CFT with Galilean symmetry. We analyze the convexity conditions \cite{bachas} for $Q\bar Q$ potential in this theory, and obtain restrictions for the acceptable dynamical exponent $z$.

Stellar Encounters with Multiple Star Systems and the Blue Straggler Problem

description: We present a technique to identify the most probable dynamical formation scenario for an observed binary or triple system containing one or more merger products or, alternatively, to rule out the possibility of a dynamical origin. Our method relies on an analytic prescription for energy conservation during stellar encounters. With this, observations of the multiple star system containing the merger product(s) can be used to work backwards in order to constrain the initial orbital energies of any single, binary or triple systems that went into the encounter. The initial semi-major axes of the orbits provide an estimate for the collisional cross section and therefore the time-scale for the encounter to occur in its host cluster. We have applied our analytic prescription to observed binary and triple systems containing blue stragglers, in particular the triple system S1082 in M67 and the period distribution of the blue straggler binaries in NGC 188. We have shown that both S1082 and most of the blue straggler binaries in NGC 188 could have a dynamical origin, and that encounters involving triples are a significant contributor to blue straggler populations in old open clusters. In general, our results suggest that encounters involving triples could make up a significant fraction of those dynamical interactions that result in stellar mergers, in particular encounters that produce multiple star systems containing one or more blue stragglers.

The DIVING$^\mathrm{3D}$ Survey - Deep IFS View of Nuclei of Galaxies - III. Analysis of the nuclear region of the early-type galaxies of the sample

description: We analysed the nuclear region of all 56 early-type galaxies from the DIVING$^\mathrm{3D}$ Project, which is a statistically complete sample of objects that contains all 170 galaxies of the Southern Hemisphere with B < 12.0 mag and galactic latitude |b| < 15$^{\circ}$. Observations were performed with the Integral Field Unit of the Gemini Multi-Object Spectrograph. Emission lines were detected in the nucleus of 86$\pm$5% of the objects. Diagnostic diagrams were used to classify 52$\pm$7% of the objects as LINERs or Seyferts, while the other 34$\pm$6% galaxies without H$β$ or [O III] lines in their spectra were classified as weak emission line objects. Transition Objects are not seen in the sample, possibly because the seeing-limited data cubes of the objects allow one to isolate the nuclei of the galaxies from their circumnuclear regions, avoiding contamination from H II regions. A broad line region is seen in 29$\pm$6% of the galaxies. Of the 48 galaxies with emission-line nuclei, 41 have signs of AGNs. Some objects have also indications of shocks in their nuclei. Lenticular galaxies are more likely to have emission lines than ellipticals. Also, more luminous objects have higher [N II]/H$α$ ratios, which may be associated with the mass-metalicity relation of galaxies. A direct comparison of our results with the Palomar Survey indicates that the detection rates of emission lines and also of type 1 AGNs are higher in the DIVING$^\mathrm{3D}$ objects. This is a consequence of using a more modern instrument with a better spatial resolution than the Palomar Survey observations.

Dividends, earnings and expected return in the context of consumption risk
Creators: name: Qiao, Zhi
Publisher: name: University of British Columbia
Year: 2016

description: The consumption literature of asset pricing typically considers only dividend cash flows, based on the theoretical inference that consumption must equal dividends over the long run. Where it is commonly considered that dividends are the smooth permanent component of earnings, while earnings vary with the business cycle. Motivated by Lamont’s (1998) result that earnings and dividends have opposite effects on future return, we follow the empirical methodology of Boguth and Kuehn (2013) and find that dividend growth volatility and earnings growth volatility have opposite relationships to consumption volatility risk. We show that these opposing effects of dividends and earnings are components of the mechanism connecting consumption risk and investors’ expected return. These results offer insight for a piece of the equity premium puzzle, namely, why stock return volatility is large compared to consumption volatility.

description: We have directly measured quasiparticle number fluctuations in a thin film superconducting Al resonator in thermal equilibrium. The spectrum of these fluctuations provides a measure of both the density and the lifetime of the quasiparticles. We observe that the quasiparticle density decreases exponentially with decreasing temperature, as theoretically predicted, but saturates below 160 mK to 25-55 per cubic micron. We show that this saturation is consistent with the measured saturation in the quasiparticle lifetime, which also explains similar observations in qubit decoherence times.
