description: Around a metal-to-insulator transition driven by repulsive interaction (Mott transition) the single particle excitations and the collective excitations are equally important. Here we present results for the generic susceptibilities at zero temperature in the half-filled Hubbard model in infinite dimensions. Profiting from the high resolution of dynamic density-matrix renormalization at all energies, results for the charge, spin and Cooper-pair susceptibilities in the metallic and the insulating phase are computed. In the insulating phase, an almost saturated local magnetic moment appears. In the metallic phase a pronounced low-energy peak is found in the spin response.

description: This paper studies a prototype of inverse obstacle scattering problems whose governing equation is the Helmholtz equation in two dimensions. An explicit method to extract information about the location and shape of unknown obstacles from the far field operator with a fixed wave number is given. The method is based on: an explicit construction of a modification of Mittag-Leffler's function via the Vekua transform and the study of the asymptotic behaviour; an explicit density in the Herglotz wave function that approximates the modification of Mittag-Leffler's function in the bounded domain surrounding unknown obstacles; a system of inequalities derived from Kirsch's factorization formula of the far field operator. Then an indicator function which can be calculated from the far field operator acting on the density is introduced. It is shown that the asymptotic behaviour of the indicator function yields information about the visible part of the exterior of the obstacles.

description: Extending investigations of Barker, Humpherys, Lafitte, Rudd, and Zumbrun for compressible gas dynamics and Freistühler and Trakhinin for compressible magnetohydrodynamics, we study by a combination of asymptotic ODE estimates and numerical Evans function computations the one-dimensional stability of parallel isentropic magnetohydrodynamic shock layers over the full range of physical parameters (shock amplitude, strength of imposed magnetic field, viscosity, magnetic permeability, and electrical resistivity) for a $γ$-law gas with $γ\in [1,3]$. Other $γ$-values may be treated similarly, but were not checked numerically. Depending on magnetic field strength, these shocks may be of fast Lax, intermediate (overcompressive), or slow Lax type; however, the shock layer is independent of magnetic field, consisting of a purely gas-dynamical profile. In each case, our results indicate stability. Interesting features of the analysis are the need to renormalize the Evans function in order to pass continuously across parameter values where the shock changes type or toward the large-amplitude limit at frequency $λ=0$ and the systematic use of winding number computations on Riemann surfaces.

description: Recent constituent priming experiments show that Dutch and German prefixed verbs prime their stem, regardless of semantic transparency (e.g. Smolka et al. [(2014). ‘Verstehen’ (‘understand’) primes ‘stehen’ (‘stand’): Morphological structure overrides semantic compositionality in the lexical representation of German complex verbs. Journal of Memory and Language, 72, 16–36. https://doi.org/10.1016/j.jml.2013.12.002]). We examine whether the processing of opaque verbs (e.g. herhalen “repeat”) involves the retrieval of only the whole-word meaning, or whether the lexical-semantic meaning of the stem (halen as “take/get”) is retrieved as well. We report the results of an auditory semantic priming experiment with Dutch prefixed verbs, testing whether the recognition of a semantic associate to the stem (BRENGEN “bring”) is facilitated by the presentation of an opaque prefixed verb. In contrast to prior visual studies, significant facilitation after semantically opaque primes is found, which suggests that the lexical-semantic meaning of stems in opaque words is retrieved. We examine the implications that these findings have for auditory word recognition, and for the way in which different types of meanings are represented and processed.

Towards integrated microwave ice sensors for on-ground, in-flight and unmanned aerial vehicle (UAV) applications

Publisher: name: University of British Columbia
Year: 2024

description: Ice accretion on aviation surfaces imposes operational and safety challenges, severely impacting critical flight structures and equipment. For optimized ‘smart’ de-icing systems of the future, microwave resonant-based planar sensors are proposed for their high sensitivity to icing and versatility in integration. This thesis presents five microwave resonant sensors for ice sensing under simulated real-world icing conditions. Three planar ice sensors are designed for harsh roadway environments. A Split-Ring Resonator (SRR) sensor (1.2 GHz) is tested for sensitivity to icing with protective epoxy coatings. A complementary split ring resonator (CSRR) sensor with a robust epoxy-coated 1mm-thick aluminum build (1.18 GHz) monitors snow accretion. Asymmetric stripline CSRR sensors with increased shielding are implemented for exploratory time-domain-reflectometry measurements, for wired large-area sensor networks. A conformal single-port dual-frequency SRR sensor (1.9-2.2 GHz) was integrated onto a NACA 0018 airfoil with electrothermal de-icing capabilities to sense in-flight ice crystal icing (ICI). Tested in the National Research Council’s (NRC’s) Research Altitude Test Facility (RATFac) at 19,000 ft, 100 m/s, +3°C and melt ratios of 11%, 13%, 16% and 25%, the sensor differentiates %melt while monitoring de-icing and anti-icing processes. Icing on smaller Unmanned Aerial Vehicles (UAVs), drones, and electric vertical take-off and landing (eVTOL) crafts impact aerodynamics and weight, severely limiting operation. A novel multi-frequency SRR sensor (2-4 GHz) is integrated with a zone-based electrothermal de-icing system and a low interfacial-toughness coating on a NACA 0012 airfoil for location-specific accretion monitoring and zone-based ‘smart’ de-icing. Tested at the Anti-Icing Materials International Laboratory’s (AMIL) icing wind tunnel at varying LWC (0.3, 0.5 and 0.8 g/m3), airspeed (20 and 40 m/s) and temperature (-5°C: glaze, -10°C: mixed, and -20°C: rime) conditions, the sensor monitors ice accretion, tracking the real-time resonant frequency response with a maximum sensitivity of 179 MHz/mm. A fitted time-constant is found to be inversely proportional to increasing ice thickness, facilitating icing rate measurement and ice thickness prediction using real-time microwave sensors. This work represents a significant advancement in the field of microwave SRR ice sensing technology, bringing it one step closer to practical implementation as integrated location-specific ice sensors for ‘smart’ ice protection systems (IPSs).

description: Chemical gradients provide the primordial energy for biological functions by driving the mechanical movement of microscopic engines. Their thermodynamic properties remain elusive, especially concerning the dynamic change in energy demand in biological systems. In this article, we derive a constraint relation between the output power and the conversion efficiency for a chemically fueled steady-state rotary motor analogous to the $\mathrm{F}_o$ motor of ATPase. We find that the efficiency at maximum power is half of the maximum quasi static efficiency. These findings shall aid in the understanding of natural chemical engines and inspire the manual design and control of chemically fueled microscale engines.

description: The past few years have witnessed the great success of a new family of paradigms, so-called folksonomy, which allows users to freely associate tags to resources and efficiently manage them. In order to uncover the underlying structures and user behaviors in folksonomy, in this paper, we propose an evolutionary hypergrah model to explain the emerging statistical properties. The present model introduces a novel mechanism that one can not only assign tags to resources, but also retrieve resources via collaborative tags. We then compare the model with a real-world dataset: \emph{Del.icio.us}. Indeed, the present model shows considerable agreement with the empirical data in following aspects: power-law hyperdegree distributions, negtive correlation between clustering coefficients and hyperdegrees, and small average distances. Furthermore, the model indicates that most tagging behaviors are motivated by labeling tags to resources, and tags play a significant role in effectively retrieving interesting resources and making acquaintance with congenial friends. The proposed model may shed some light on the in-depth understanding of the structure and function of folksonomy.

description: The mapping of plant biodiversity represents a fundamental stage in establishing conservation priorities, particularly in identifying groups of species that share ecological requirements or evolutionary histories. This is often achieved by assessing different spatial diversity patterns in plant population distributions. In this paper, we present two primary data sources crucial for biodiversity monitoring: in situ measurements from botanical observations and remote sensing (RS). In situ methods involve directly collecting data from specific sites, providing detailed insights into ecological patterns but often constrained by resource limitations. Integrating in situ and RS data highlights their complementary strengths, which depend on factors such as study scale, resolution, and logistical feasibility. While in situ approaches are characterized by precision, RS offers efficiency and extensive, repeated coverage. This research integrates in situ and RS data to analyze plant and spectral diversity across France at a spatial resolution of 5 km, encompassing over 23,000 grid cells. We employ four established diversity metrics leveraging the spatial distribution of 6,650 plant species and 250 spectral clusters (derived from MODIS data at a 500-meter resolution). Through bioregionalization network analysis combining these data sources, we identified five distinct bioregions that capture the biogeographical structure of plant biodiversity in France. Additionally, we explore the relationship between plant species diversity and spectral cluster diversity within and between these bioregions, offering novel insights into the spatial dynamics of plant biodiversity.

description: Previous research has found that comprehenders sometimes predict information that is grammatically unlicensed by sentence constraints. An open question is why such grammatically unlicensed predictions occur. We examined the possibility that unlicensed predictions arise in situations of information conflict, for instance when comprehenders try to predict upcoming words while simultaneously building dependencies with previously encountered elements in memory. German possessive pronouns are a good testing ground for this hypothesis because they encode two grammatically distinct agreement dependencies: a retrospective one between the possessive and its previously mentioned referent, and a prospective one between the possessive and its following nominal head. In two visual world eye-tracking experiments, we estimated the onset of predictive effects in participants’ fixations. The results showed that the retrospective dependency affected resolution of the prospective dependency by shifting the onset of predictive effects. We attribute this effect to an interaction between predictive and memory retrieval processes.
Constant pressure invasion of viscoplastic suspensions in thin conduits
Creators: name: Izadi, Mahdi
Publisher: name: University of British Columbia
Year: 2024

description: This thesis presents a numerical study of the flow and stoppage of a viscoplastic fluid invading into a thin, non-uniform channel. The fluid represents a cementitious sealant, and the invasion aims to regulate gas flow through the partially filled channel. The flows are driven under constant pressure and arrested due to fluid yield stress. The gas flow through the channel, modeled as a Hele-Shaw cell, is calculated using a thin gap approximation and computed before and after the invasion. Motivated by industrial applications from squeeze cementing, the first objective is to investigate the fluid interface morphology at the stoppage, i.e., how effectively the fluid blocks the gap. We present a gap-averaged framework to study the interface morphology for radial injection into a Hele-Shaw geometry, where the gap thickness variations are defined using realistic industrial data and a stochastic model. We quantify the interface morphology to investigate the effect of different parameters. Our results reveal an enormous variability resulting from the geometrical uncertainties. The second objective of the thesis is to devise a gap-averaged model for a multisource injection, where the fluid is injected into the Hele-Shaw geometries from patterned injection points. We develop a method by stacking radial injection scenarios to reconstruct the whole section. We investigate the effect of perforation patterns and rheological parameters on the leakage flow rate. We generate a probability distribution of leakage rates to estimate the mean reduction in flow leakage and compute confidence intervals. Our results suggest that higher perforation density and lower yield stress slurry lead to higher success rates. The final objective of this thesis is to study the invasion of a viscoplastic suspension into a thin channel. We consider the multiphase nature of the suspension and compute the transverse distribution evolution of liquid and solid phases during flow. The aim is to explore various phenomena, such as particle migration, jamming, and yield surface position. This allows us to validate the accuracy of gap-averaged models, i.e., how ignoring transverse flow parameters affects penetration depth estimation. It also points toward new and more complex physical models for processes such as squeeze cementing.

description: Strong emotional words tend to command attention and disrupt cognitive processing. Three experiments investigated whether taboo context, defined by the inclusion of taboo distractors in a picture-word interference task, influences how a distractor’s emotional properties affect speech production. Participants named target pictures accompanied by written distractors varying in arousal and valence. Trials were presented in blocks with negative, positive, and neutral distractors that also included or omitted taboo distractors. Results showed that positive distractors had no significant effect on naming times, whereas negative distractors slowed picture naming only when they were higher in arousal and only in a taboo block. Naming times were slower overall in the taboo context compared to the non-taboo context. These findings suggest that the presence of taboo words changes the influence of non-taboo emotional words during speech production, which has implications for the role of attention in speech production theories and more broadly for cognition.

description: Calcium imaging for observing spiking activity from large populations of neurons are quickly gaining popularity. While the raw data are fluorescence movies, the underlying spike trains are of interest. This work presents a fast non-negative deconvolution filter to infer the approximately most likely spike train for each neuron, given the fluorescence observations. This algorithm outperforms optimal linear deconvolution (Wiener filtering) on both simulated and biological data. The performance gains come from restricting the inferred spike trains to be positive (using an interior-point method), unlike the Wiener filter. The algorithm is fast enough that even when imaging over 100 neurons, inference can be performed on the set of all observed traces faster than real-time. Performing optimal spatial filtering on the images further refines the estimates. Importantly, all the parameters required to perform the inference can be estimated using only the fluorescence data, obviating the need to perform joint electrophysiological and imaging calibration experiments.

description: We have performed a detailed abundance analysis of the content of s-process elements of two dwarf stars with suspected overabundace of those elements. Such stars belong to a special kinematic sample of the solar neighborhood, with peculiar kinematics and different chemical abundances when compared to "normal" disk stars. We aim to define if those stars can be identified as barium stars, based on their s-process elements abundances, and their classification, i.e., if they share their chemical profile with strong or mild barium stars. We also intend to shed light on the possible origins of the different kinds of barium stars. Spectra have been taken by using the FEROS spectrograph at the 1.52m telescope of ESO, La Silla. Abundances have been derived for 18 elements, by matching the synthetic profile with the observed spectrum. We have found that HD 11397 shows a mild enhancement for most of the s-process elements as well as for some r-process elements. This star seems to share its abundance profile with the mild Ba-stars. Although showing some slight chemical anomalies for Y, Sr, Mo, and Pb, HD 14282 depicts a chemical pattern similar to the normal stars with slight s-process enhancements.

description: In this preregistered study, we investigate whether themes conveyed by task partners’ narratives reveal semantic relationships between objects that would otherwise be perceived as unrelated. Such ad-hoc formation of thematic relations should result in semantic interference when naming objects related to the theme in a blocked-cyclic naming paradigm. Participants watch pre-recorded videos of presumed partners narrating real-life events, and then name pictures either thematically related or unrelated to the narrative. Experiments 1 and 2 (N = 32 each) demonstrate semantic interference between objects related to the partner's narrative. Interestingly, this effect emerges only when unrelated pictures are named first. Interference is greatly attenuated, or even turns into facilitation when related pictures are named directly after the partner's narrative. Experiment 3 (N = 32) confirms that semantic context effects disappear when the objects cannot be related to the narrative. Our results demonstrate how flexible semantic processing adapts to context communicated by a task partner.

description: We have carried out scanning tunneling spectroscopy measurements on exfoliated monolayer graphene on SiO$_2$ to probe the correlation between its electronic and structural properties. Maps of the local density of states are characterized by electron and hole puddles that arise due to long range intravalley scattering from intrinsic ripples in graphene and random charged impurities. At low energy, we observe short range intervalley scattering which we attribute to lattice defects. Our results demonstrate that the electronic properties of graphene are influenced by intrinsic ripples, defects and the underlying SiO$_2$ substrate.

description: For actions with a dense orbit of a connected noncompact simple Lie group $G$, we obtain some global rigidity results when the actions preserve certain geometric structures. In particular, we prove that for a $G$-action to be equivalent to one on a space of the form $(G\times K\backslash H)/Γ$, it is necessary and sufficient for the $G$-action to preserve a pseudo-Riemannian metric and a transverse Riemannian metric to the orbits. A similar result proves that the $G$-actions on spaces of the form $(G\times H)/Γ$ are characterized by preserving transverse parallelisms. By relating our techniques to the notion of the algebraic hull of an action, we obtain infinitesimal Lie algebra structures on certain geometric manifolds acted upon by $G$.

description: As a sister work of Ref.[1], we incorporate the color-screening effect due to light quark pair creation into the heavy quark-antiquark potential, and investigate the effects of screened potential on the spectrum of bottomonium. We calculate the masses, electromagnetic decays, and E1 transitions of bottomonium states. We find that the fine splittings between $χ_{bJ}$ (J=0,1,2) states are in good agreement with experimental data, and the E1 transition rates of $Υ(2S)\toγχ_{bJ}(1P)$ and $Υ(3S)\toγχ_{bJ}(2P)$ (J=0,1,2) all agree with data within experimental errors. In particular, the mass of $Υ(6S)$ is lowered down to match that of the $Υ(11020)$, which is smaller than the predictions of the linear potential models by more than 100 MeV. Comparison between charmonium and bottomonium in some related problems is also discussed.

description: The aim of this paper is to look at the magnetic helicity structure of an emerging active region and show that both emergence and flaring signatures are consistent with a same sign for magnetic helicity. We present a multi-wavelength analysis of an M1.6 flare occurring in the active region NOAA 10365 on 27 May, 2003, in which a large new bipole emerges in a decaying active region. The diverging flow pattern and the "tongue" shape of the magnetic field in the photosphere with elongated polarities are highly suggestive of the emergence of a twisted flux tube. The orientation of these tongues indicates the emergence of a flux tube with a right hand twist, i.e. positive magnetic helicity. The flare signatures in the chromosphere are ribbons observed in H-alpha by the MSDP spectrograph in the Meudon solar tower and in 1600 A by TRACE. These ribbons have a `J' shape and are shifted along the inversion line. The pattern of these ribbons suggests that the flare was triggered by magnetic reconnection at coronal heights below a twisted flux tube of positive helicity, corresponding to that of the observed emergence. It is the first time that such a consistency between the signatures of the emerging flux through the photosphere and flare ribbons is clearly identified in observations. Another type of ribbons observed during the flare at the periphery of the active region by the MSDP and SOHO/EIT are related to the existence of a null point, which is found high in the corona in a potential field extrapolation. We discuss the interpretation of these secondary brightenings in terms of the "breakout" model and in terms of plasma compression/heating within large-scale separatrices.

description: Context can affect language processing and learning. We here compare the influence of two different contexts (pseudo-objects, data from [Obrig, H., Mock, J., Stephan, F., Richter, M., Vignotto, M., & Rossi, S. (2017). Impact of associative word learning on phonotactic processing in 6-month-old infants: A combined EEG and fNIRS study. Developmental Cognitive Neuroscience, 25, 185–197. https://doi.org/10.1016/j.dcn.2016.09.001] , vs. real objects) on the processing of phonotactically legal vs. illegal pseudowords (PW) in a 3-day learning paradigm in 6-month-olds. Using ERPs and functional Near InfraRed Spectroscopy (fNIRS) we find that short-term (pre-→post-test) and long-term (day1→ day2→day3) attunement to pseudowords is affected by both, learning context and phonotactic status. When real objects are used, fNIRS shows a long-term increase in response magnitude for legal PW. ERPs show a long-term decrease in negativities in response to trained legal PW. Conversely, the pseudo-objects context elicits neuronal attunement to all PW. We propose that legal PW in a real object context cause conflict, leading to difficulties in lexical integration. However, training eases lexical integration of trained legal PW through priming. Our results speak for the early relevance of phonotactics and context in language acquisition.

description: The standard cosmological model is assumed to respect parity symmetry. Under this assumption the cross-correlations of the CMB's temperature anisotropy and `gradient'-like polarization, with the `curl'-like polarization identically vanish over the full sky. However, extensions of the standard model which allow for light scalar field or axion coupling to the electromagnetic field, or coupling to the Riemann gravitational field-strength, as well as other modifications of field theories, may induce a rotation of the CMB polarization plane on cosmological scales and manifest itself as nonvanishing TB and EB cross-correlations. Recently, the degree of parity violation (reflected in polarization rotation) was constrained using data from BOOMERANG, WMAP and QUAD. Forecasts have been made for near-future experiments (e.g. PLANCK) to further constrain parity- and Lorentz-violating terms in the fundamental interactions of nature. Here we consider a real-world effect induced by a class of telescope beam systematics which can mimic the rotation of polarization plane or otherwise induce nonvanishing TB and EB correlations. In particular, adopting the viewpoint that the primary target of future experiments will be the inflationary B-mode signal, we assume the beam-systematics of the upcoming PLANCK and POLARBEAR experiments are optimized towards this goal, and explore the implications of the allowed levels of beam systematics on the resulting precision of polarization-rotation measurements.

description: The CH2Cl2/MeOH (1:1) extract of Zanthoxylum holstzianum stem bark showed good antiplasmodial activity (IC50 2.5 ± 0.3 and 2.6 ± 0.3 µg/mL against the W2 and D6 strains of Plasmodium falciparum, respectively). From the extract five benzophenanthridine alkaloids [8-acetonyldihydrochelerythrine (1), nitidine (2), dihydrochelerythine (3), norchelerythrine (5), arnottianamide (8)]; a 2-quinolone alkaloid [N-methylflindersine (4)]; a lignan [4,4′-dihydroxy-3,3′-dimethoxylignan-9,9′-diyl diacetate (7)] and a dimer of a benzophenanthridine and 2-quinoline [holstzianoquinoline (6)] were isolated. The CH2Cl2/MeOH (1:1) extract of the root bark afforded 1, 3–6, 8, chelerythridimerine (9) and 9-demethyloxychelerythrine (10). Holstzianoquinoline (6) is new, and is the second dimer linked by a C-C bond of a benzophenanthridine and a 2-quinoline reported thus far. The compounds were identified based on spectroscopic evidence. Amongst five compounds (1-5) tested against two strains of P. falciparum, nitidine (IC50 0.11 ± 0.01 µg/mL against W2 and D6 strains) and norchelerythrine (IC50 value of 0.15 ± 0.01 µg/mL against D6 strain) were the most active.

description: The structure of helminth communities in wild rodents is subject to seasonal variation, and is dependent on host age within years. Although between-year variation has been monitored, seldom has it been assessed rigorously by appropriate multifactorial analysis with potentially confounding factors taken into account. In this study we tested the null hypothesis that despite seasonal, host age and sex effects, helminth communities should show relative stability between years. Over a period of 3 years (1998–2000) we sampled bank vole (Clethrionomys glareolus) populations (totaln=250) at 2 points in the year: in spring, at the start of the breeding season, and in autumn, after the cessation of breeding. In spite of seasonal differences and strong age effects, the between-year effects were surprisingly small. Measures of component community structure (Berger-Parker dominance index, the dominant species,S. petrusewiczi) did not vary, or varied only slightly from year to year. The majority of measures of infracommunity structure [Brillouin's index of diversity, prevalence of all helminths combined, prevalence and abundance ofH. mixtum(the most prevalent helminth), mean species richness] did not differ significantly between years when other factors such as age, sex and seasonal variation had been taken into account. Some between-year variations were found (at the component community level, Simpson's index of diversity; at the infracommunity level, prevalence and abundance ofS. petrusewicziand abundance of all helminths combined), but even these were modest in comparison to seasonal and age differences, and were primarily attributable toS. petrusewiczi. We conclude that despite dynamic within-year fluctuations, helminth communities in bank voles in this region of Poland show relative stability across years. The sporadic occurrence of individual platyhelminths at low prevalence, makes little difference to the overall structure, which is largely maintained by the key roles played by the dominant intestinal nematodes of bank voles and the rarer species collectively.
Evolutionary dynamics and fixation probabilities in directed networks

description: We investigate the evolutionary dynamics in directed and/or weighted networks. We study the fixation probability of a mutant in finite populations in stochastic voter-type dynamics for several update rules. The fixation probability is defined as the probability of a newly introduced mutant in a wild-type population taking over the entire population. In contrast to the case of undirected and unweighted networks, the fixation probability of a mutant in directed networks is characterized not only by the degree of the node that the mutant initially invades but by the global structure of networks. Consequently, the gross connectivity of networks such as small-world property or modularity has a major impact on the fixation probability.

description: We use deep (~27.5 mag V-band point-source limiting magnitude) V- and U-band LBT imaging to study the outer disk (beyond the optical radius R_25) of the non-interacting, face-on spiral galaxy NGC 3184 (D = 11.1 Mpc; R_25 = 11.1 kpc) and find that this outer disk contains >1000 objects (or marginally-resolved 'knots') resembling star clusters with masses ~10^2 - 10^4 M_sun and ages up to ~1 Gyr. We find statistically significant numbers of these cluster-like knots extending to ~1.4 R_25, with the redder knots outnumbering bluer at the largest radii. We measure clustering among knots and find significant correlation to galactocentric radii of 1.5 R_25 for knot separations <1 kpc. The effective integrated surface brightness of this outer disk cluster population ranges from 30 - 32 mag arcsec^-2 in V. We compare the HI extent to that of the correlated knots and find that the clusters extend at least to the damped Lyman-alpha threshold of HI column density (2e20 cm^-2; 1.62 R_25). The blue knots are correlated with HI spiral structure to 1.5 R_25, while the red knots may be correlated with the outer fringes of the HI disk to 1.7 R_25. These results suggest that outer disks are well-populated, common, and long-lasting features of many nearby disk galaxies.
