Effect of di-butyl phthalate exposure in the human airway and systemic immunology : a double-blind, crossover study
Creators: name: Maestre-Batlle, Danay
Publisher: name: University of British Columbia
Year: 2019

description: Phthalates are used as softeners in commercial products. They leak into the environment and become wide-spread contaminants. Epidemiological studies suggest an association between phthalate inhalation and development/worsening of airway diseases, but a firm link has not been established. Asthma is a complex disorder associated with inflammation resulting in airway hyper-responsiveness (AHR). Increasing interest is focused on abnormal immune responses as an underlying mechanism contributing to increasing the risk of asthma. This study is the first to investigate airway and systemic effects in humans due to inhalation of a known concentration of a single phthalate. Di-butyl phthalate (DBP), exists in high concentrations in indoor air and has shown inflammatory potential. We hypothesize that DBP inhalation, prior to allergen inhalation will: a) enhance airway inflammation and responsiveness to allergen, and b) alter the activation state and functionality of immune cells in the airway and peripheral blood. In this novel double-blind, order-randomized, crossover study, 16 participants were exposed by inhalation to controlled levels of DBP or clean air (CA) for 3h, followed immediately by an allergen (dust-mite, grass or birch) inhalation. To assess lung function and airway inflammation, spirometry and exhaled nitric oxide was measured before, 3h and 20h post-DBP/CA exposure and allergen inhalation. Blood, bronchoalveolar wash and lavage (BAL) were collected for quantification and measurement of the activation pattern of immune cells and inflammatory mediator release. DBP inhalation followed by an allergen inhalation, significantly augmented the airflow decline (FEV1) in response to an inhaled allergen, compared to CA. Moreover, DBP enhanced the recruitment of BAL macrophages, specifically the M2 phenotype with increased expression of CD206 to the lungs. Meanwhile, the percent of T helper cells increased, while T regulatory and non-classical monocytes decreased, in peripheral blood. Only minor effects were observed for systemic inflammatory mediators. Moreover, significant effect modifications were observed for sex, AHR status and type of allergen inhaled. The results suggest significant effects of a common commercial chemical, DBP, on clinically relevant airway and systemic endpoints in the context of allergen exposure in sensitized individuals. Future research should aim to validate and connect these findings within relevant policy and public health contexts.
Effective and efficient transport mechanism of CO$_2$ in subnano-porous crystalline membrane of syndiotactic polystyrene
Creators: name: Tamai, Yoshinori

Year: 2022
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: The gas permeation behavior in the single crystal of syndiotactic polystyrene (s-PS) S-I form was investigated in detail, in comparison to that in the s-PS $\varepsilon$ form. The S-I form exhibits high CO$_2$/N$_2$ and CO$_2$/CH$_4$ separation factors while preserving its high CO$_2$ permeability; a trade-off between selectivity and permeability was broken through.The mechanism of the effective and efficient transport of CO$_2$ in the S-I form was examined in relation to the cavity structure in the crystal. Because the CO$_2$ molecule is only fitted to the cavities in the S-I form, the solubility of CO$_2$ becomes high. In addition, tri-atomic molecules can more effectively diffuse in the S-I form compared with di-atomic molecules, as proved by the "long-gas" model. A novel design criterion for the CO$_2$ separation membranes is proposed based on the aspect of momentum transfer from polymer matrix to the penetrant.

description: One of the longstanding unsolved problems of planet formation is how solid bodies of a few decimeters in size can "stick" to form large planetesimals. This is known as the "meter size barrier". In recent years it has become increasingly clear that some form of "particle trapping" must have played a role in overcoming the meter size barrier. Particles can be trapped in long-lived local pressure maxima, such as those in anticyclonic vortices, zonal flows or those believed to occur near ice lines or at dead zone boundaries. Such pressure traps are the ideal sites for the formation of planetesimals and small planetary embryos. Moreover, they likely produce large quantities of such bodies in a small region, making it likely that subsequent N-body evolution may lead to even larger planetary embryos. The goal of this Letter is to show that this indeed happens, and to study how efficient it is. In particular, we wish to find out if rocky/icy bodies as large as 10 M_earth can form within 1 Myr, since such bodies are the precursors of gas giant planets in the core accretion scenario.

The role of prior experience in the integration of aerotactile speech information
Creators: name: Keough, Megan
Publisher: name: University of British Columbia
Year: 2019

description: Perceivers receive a constant influx of information about the natural world via their different senses. In recent years, speech researchers have begun to situate speech more firmly within this multisensory experience, moving progressively away from the traditional focus on audition toward a more multisensory approach. In doing so, speech researchers have discovered that, in addition to audition and vision, many somatosenses are all highly relevant modalities for experiencing and/or conveying speech. The current dissertation focuses on the integration of aerotactile somatosensation—the feeling of speech-related airflow on the skin—and whether prior experience with specific speech information modulates aerotactile influence on visual and auditory speech cues to English stops. In Chapter 2, I used a two-alternative forced choice visuo-aerotactile perception task to show that adult English perceivers can integrate aerotactile speech information from a novel visual source. In Chapter 3, I used a two-alternative forced choice audio-aerotactile perception task to demonstrate integration occurs for this population even when the auditory and aerotactile speech cues are presented in a way that does not conform with previous prior experience in the natural world. Finally, in Chapter 4 I used a looking time procedure to test prelinguistic infants on their sensitivity to speech-related airflow during auditory perception and found no evidence that infant stop perception can be influenced by airflow before infants begin babbling. Taken together, these three experiments suggest that while adult perceivers can integrate aerotactile speech information with speech information from other modalities without specific prior experience with the cues, some developmental experience may be required for this ability to emerge.
How Sensitive is the CMB to a Single Lens?

description: We study the imprints of a single lens, that breaks statistical isotropy, on the CMB and calculate the signal to noise ratio (S/N) for its detection. We emphasize the role of non-Gaussianities induced by LCDM weak lensing in this calculation and show that typically the S/N is much smaller than expected. In particular we find that the hypothesis that a void (texture) is responsible for the WMAP cold spot can barely (cannot) be tested via weak lensing of the CMB.

description: Recent advances in miniaturization and commercial availability of critical satellite subsystems and detector technology have made small satellites (SmallSats, including CubeSats) an attractive, low-cost potential solution for space weather research and operational needs. Motivated by the 1st International Workshop on SmallSats for Space Weather Research and Forecasting, held in Washington, DC on 1-4 August 2017, we discuss the need for advanced space weather measurement capabilities, driven by analyses from the World Meteorological Organization (WMO), and how SmallSats can efficiently fill these measurement gaps. We present some current, recent missions and proposed/upcoming mission concepts using SmallSats that enhance space weather research and provide prototyping pathways for future operational applications; how they relate to the WMO requirements; and what challenges remain to be overcome to meet the WMO goals and operational needs in the future. With additional investment from cognizant funding agencies worldwide, SmallSats -- including standalone missions and constellations -- could significantly enhance space weather research and, eventually, operations, by reducing costs and enabling new measurements not feasible from traditional, large, monolithic missions.

description: I arrived in Berkeley in 1957, at which time Leo was an Acting Assistant Professor of Mathematics here. He had recently proven the "individual ergodic theorem of information theory"---a triumph---and since this was becoming central to my own interests, it would have been natural for us to work together. However, Leo's interests shifted to more applied work, specifically statistics, and he soon moved to UCLA. So we never became collaborators, but we did became good friends, especially after 1980 when he returned to Berkeley as a Professor of Statistics.

description: The quasispecies model of biological evolution for asexual organisms such as bacteria and viruses has attracted considerable attention of biological physicists. Many variants of the model have been proposed and subsequently solved using the methods of statistical physics. In this paper I will put forward important but largely overlooked relations between localization theory, random matrices, and the quasispecies model. These relations will help me to study the dynamics of this model. In particular, I will show that the distribution of times between evolutionary jumps in the genotype space follows a power law, in agreement with recent findings in the shell model - a simplified version of the quasispecies model.

Top-heavy integrated galactic stellar initial mass functions (IGIMFs) in starbursts

description: Star formation rates (SFR) larger than 1000 Msun/ yr are observed in extreme star bursts. This leads to the formation of star clusters with masses > 10^6 Msun in which crowding of the pre-stellar cores may lead to a change of the stellar initial mass function (IMF). Indeed, the large mass-to-light ratios of ultra-compact dwarf galaxies and recent results on globular clusters suggest the IMF to become top-heavy with increasing star-forming density. We explore the implications of top-heavy IMFs in these very massive and compact systems for the integrated galactic initial mass function (IGIMF), which is the galaxy-wide IMF, in dependence of the star-formation rate of galaxies. The resulting IGIMFs can have slopes, alpha_3, for stars more massive than about 1 Msun between 1.5 and the Salpeter slope of 2.3 for an embedded cluster mass function (ECMF) slope (beta) of 2.0, but only if the ECMF has no low-mass clusters in galaxies with major starbursts. Alternatively, beta would have to decrease with increasing SFR >10 Msun/ yr such that galaxies with major starbursts have a top-heavy ECMF. The resulting IGIMFs are within the range of observationally deduced IMF variations with redshift.

Non-Fermi liquid signatures in the Hubbard Model due to van Hove singularities

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: When a van-Hove singularity is located in the vicinity of the Fermi level, the electronic scattering rate acquires a non-analytic contribution. This invalidates basic assumptions of Fermi liquid theory and within perturbative treatments leads to a non-Fermi liquid self-energy and transport properties.Such anomalies are shown to also occur in the strongly correlated metallic state. We consider the Hubbard model on a two-dimensional square lattice with nearest and next-nearest neighbor hopping within the single-site dynamical mean-field theory. At temperatures on the order of the low-energy scale $T_0$ an unusual maximum emerges in the imaginary part of the self-energy which is renormalized towards the Fermi level for finite doping. At zero temperature this double-well structure is suppressed, but an anomalous energy dependence of the self-energy remains. For the frustrated Hubbard model on the square lattice with next-nearest neighbor hopping, the presence of the van Hove singularity changes the asymptotic low temperature behavior of the resistivity from a Fermi liquid to non-Fermi liquid dependency as function of doping. The results of this work are discussed regarding their relevance for high-temperature cuprate superconductors.

description: Physical picture of the emission mechanisms operating in the X-ray binaries was put under question by the simultaneous optical/X-ray observations with high time resolution. The light curves of the two energy bands appeared to be connected and the cross-correlation functions observed in three black hole binaries exhibited a complicated shape. They show a dip of the optical emission a few seconds before the X-ray peak and the optical flare just after the X-ray peak. This behavior could not be explained in terms of standard optical emission candidates (e.g., emission from the cold accretion disk or a jet). We propose a novel model, which explains the broadband optical to the X-ray spectra and the variability properties. We suggest that the optical emission consists of two components: synchrotron radiation from the non-thermal electrons in the hot accretion flow and the emission produced by reprocessing of the X-rays in the outer part of the accretion disk. The first component is anti-correlated with the X-rays, while the second one is correlated, but delayed and smeared relative to the X-rays. The interplay of the components explains the complex shape of the cross-correlation function, the features in the optical power spectral density as well as the time lags.

description: Large-scale statistical analysis of data sets associated with genome sequences plays an important role in modern biology. A key component of such statistical analyses is the computation of $p$-values and confidence bounds for statistics defined on the genome. Currently such computation is commonly achieved through ad hoc simulation measures. The method of randomization, which is at the heart of these simulation procedures, can significantly affect the resulting statistical conclusions. Most simulation schemes introduce a variety of hidden assumptions regarding the nature of the randomness in the data, resulting in a failure to capture biologically meaningful relationships. To address the need for a method of assessing the significance of observations within large scale genomic studies, where there often exists a complex dependency structure between observations, we propose a unified solution built upon a data subsampling approach. We propose a piecewise stationary model for genome sequences and show that the subsampling approach gives correct answers under this model. We illustrate the method on three simulation studies and two real data examples.

description: Using the data set of The Three Hundred project, i.e. a suite of 324 hydrodynamical resimulations of cluster-sized haloes, we study galaxy cluster mergers and their effect on colour and luminosity changes of their brightest cluster galaxies (BCG). We track the main progenitor of each halo at z=0 and search for merger situations based on its mass accretion history, defining mergers as very rapid increases in the halo mass. Based upon the evolution of the dynamical state of the cluster we define a pre- and post-merger phase. We create a list of all these events and statistically study their mass ratio and timescales, with the former verifying that all instances are in fact major mergers. By comparing to a control sample of clusters without mergers, we study the effect mergers have on the stellar component of the BCG. Analysing the mass, age and metallicity of the BCG stellar particles, we find that the stellar content of BCGs grows significantly during mergers and, even though the main growth mechanism is the accretion of older stars, there is even a burst in star formation induced by the merger. In our simulations, BCGs in mergers form in median around 70 per cent more stars than those normally growing, although this depends on the radius considered for defining the BCG. Regarding observable properties, we see an increase in SDSS-u luminosity of 20 per cent during mergers, accompanied by a slightly slower increase of the galaxy g-r colour as compared to the control sample.

Constraining the mixing matrix for Standard Model with four generations: time dependent and semi-leptonic CP asymmetries in $B_d^0$, $B_s$ and $D^0$

description: Using existing experimental information from K, B and D decays as well as electroweak precision tests and oblique parameters, we provide constraints and correlations on the parameters of the 4X4 mixing matrix for the Standard Model with four generations (SM4). We emphasize that some correlations amongst the parameters have important repercussions for key observables. We work with a particular representation of this matrix which is highly suited for extracting information from B-decays. Implications of the resulting constraints for time dependent and semileptonic CP asymmetries for $D^0$, $B^0$ and for $B_s$ are also given. While we show that the semi-leptonic asymmetries may be significantly enhanced in SM4 over the SM, there are important constraints and correlations with other observables. In this context we suggest that existing data from B-factories taken on $Υ(4S)$ and $Υ(5S)$, and in the relevant continuum be used to constrain the semi-leptonic asymmetries for $B_d$, $B_s$ as well as their linear combination. Of course, the data from the Tevatron and LHCb experiments can provide non-trivial tests of SM4 as well.

Design, synthesis and studies of guanidinium-based inhibitors for isoprenoid biosynthetic pathway enzymes
Creators: name: Abdelmagid, Walid
Publisher: name: University of British Columbia
Year: 2019

description: In this thesis an inhibition strategy was developed to target enzymes that utilize allylic diphosphates. Positively-charged inhibitors that mimic the transition states/intermediates formed with these enzymes were synthesized. In chapter two, inhibitor 2 containing a guanidinium moiety appended to a phosphonylphosphinate was designed to mimic the transition state for the dissociation of dimethylallyl diphosphate into an allylic carbocation-pyrophosphate ion-pair. To test for the effectiveness of incorporating a guanidinium functionality into inhibitors of human farnesyl diphosphate synthase, inhibitors 3 and 4 were also prepared. Inhibitor 3 has a positive charge localized onto one atom, and inhibitor 4 is isosteric to inhibitor 2, but lacks positive charge. The inhibitors displayed IC50 values that were significantly higher than the substrate Km value, indicating that the positive charge did not result in tight binding to the enzyme. We decided to apply our inhibition strategy on other allylic diphosphate utilizing-enzymes. In chapter three, inhibitors bearing a guanidinium/amidinium moiety appended to a phosphonylphosphinate and flanked by a hydrocarbon tail (inhibitors 26 and 36) were synthesized. A neutral inhibitor 34 was also prepared as control. These inhibitors were tested against human squalene synthase (HSQS) and bacterial dehydrosqualene synthase (DSQS) from Staphylococcus aureus. It was anticipated that the lipid chain might increase the enzyme’s affinity towards the inhibitors. The positively-charged inhibitors acted as competitive inhibitors (low micromolar KI values) against DSQS. Similar trends were observed for the first half reaction of HSQS. Surprisingly, the neutral inhibitor was the most potent for both enzymes. These results indicated that the active site of both enzymes does not directly stabilize the allylic carbocation. We reasoned that these positively-charged inhibitors might be effective with enzymes that generate carbocation intermediates that are not stabilized by resonance or ion-pair interactions. Such a strategy was applied in chapter four, where inhibitors 2 – 4 were tested against isopentenyl diphosphate isomerase (IDI), and acted as competitive inhibitors of IDI. Notably, inhibitor 2 bound 400 times more tightly than its neutral isostere, inhibitor 4. We reasoned that inhibitor 2 allows for proper positioning of the positive charge in the active site, leading to favorable electrostatic interactions.
