title: Detection and control of calcium carbonate formation and phase conversion: laboratory and field work
Creators: name: Gao, Boyang
Publisher: name: Memorial University of Newfoundland
Year: 2023

description: This thesis work relates to calcium carbonate (CaCO₃) polymorphism, focusing on crystallization and dissolution in non-equilibrium situations, to show why understanding CaCO₃ chemistry can help control the reactivity of both laboratory-synthesized and naturally occurring carbonate minerals. My laboratory work focused on how two CaCO₃ polymorphs, calcite and aragonite, dissolve and recrystallize in aqueous solution. The experimental results show that aragonite dissolves (and recrystallizes as calcite) faster when there is more calcite present with it. To understand the chemistry behind this observation, the solubility constant and recrystallization rates of each polymorph need to be considered. These results show why putting these two polymorphs together in water causes a non-equilibrium situation that cannot be well-described by their solubility constants alone. In addition, the dissolution-recrystallization behavior of mixed powder is tremendously retarded by the addition of a small amount of polyphosphate in the suspension. Based on bulk and surface characterization data (Infrared Spectroscopy and Solid-state Nuclear Magnetic Resonance), the phosphate species is incorporated only near the CaCO₃ particle surface without forming any separate phosphate-rich phase as a protecting shell. These data show that such dispersed surface-embedded phosphate entities stabilize solids against recrystallization in an aqueous environment. Moreover, polyphosphate treatment can also slightly improve the thermal stability of aragonite in terms of phase conversion. The thesis work also applies similar carbonate chemistry knowledge to characterization method development for field research. Carbonate mineral deposits are a surface manifestation of serpentinization, a water-rock reaction that provides energy and carbon sources that could support microbial life on serpentine-rich areas of Earth, or even on other planets like Mars. Infrared spectra from this study identify calcite and aragonite phases from ground-truthed samples. Based on literature from both laboratory- and field-based studies, the presence of aragonite could be due to high pH water and magnesium ions produced by serpentinization. Similar literature shows that calcite could be formed directly or caused by phase conversion of aragonite over time. However, the period required for the phase transformation is unknown. The thesis work describes how knowledge of carbonate polymorph control in a laboratory setting can help us begin to understand what geochemical factors may be necessary for phase selection during the serpentinization process.

description: Introduction: Faecal sludge management (FSM) in urban areas of low-and middle-income countries (LMICs) is not properly implemented due to inaccessibility of sanitation facilities and high faecal sludge (FS) emptying costs, amongst others. Unlike in solid waste and fresh human excreta, use of black soldier fly larvae (BSFL) in treatment of FS from pit latrines - which are the most common sanitation facilities in urban areas of LMICs - has not yet been explored. Moreover, the optimal conditions for efficient FS degradation, such as moisture content, feeding rate and larval density are not yet well known. Against this backdrop, the overarching aim of this study was to determine the effectiveness of BSFL in treating FS under different conditions of moisture content, feeding rate and larval density. Also, the quality of residue left after treatment was assessed.Methods: FS samples were collected from lined and unlined pit latrines in Bwaise I parish in Kampala, Uganda and experiments were set up to feed 10-day old larvae.Results and Discussion: The optimum feeding rate, larval density and moisture content were found to be 50 mg/larvae/day, 1.33 larvae/cm2 and 60%, respectively. The reduction efficiency at optimum conditions were 72% and 66% for FS from lined and unlined pit latrines, respectively. It was further noted that BSFL can feed on FS from pit latrines without dewatering it, hence there is no need for a dewatering unit. The properties of the residue left after treatment were within the allowable limit for use as compost except for helminth egg concentration. Thus, in informal urban settlements, BSFL can be applied for effective treatment of FS from pit latrines while generating good quality residue thereby providing an additional value chain in FSM.

description: Results from UBVRI photometric observations of the pre-main sequence star GM Cep obtained in the period April 2011 - August 2014 are reported in the paper. Presented data are a continuation of our photometric monitoring of the star started in 2008. GM Cep is located in the field of the young open cluster Trumpler 37 and over the past years it has been an object of intense photometric and spectral studies. The star shows a strong photometric variability interpreted as a possible outburst from EXor type in previous studies. Our photometric data for a period of over six years show a large amplitude variability (Delta V ~ 2.3 mag.) and several deep minimums in brightness are observed. The analysis of the collected multicolor photometric data shows the typical of UX Ori variables a color reversal during the minimums in brightness. The observed decreases in brightness have a different shape, and evidences of periodicity are not detected. At the same time, high amplitude rapid variations in brightness typical for the classical T Tauri stars also present on the light curve of GM Cep. The spectrum of GM Cep shows the typical of classical T Tauri stars wide H/alpha emission line and absorption lines of some metals. We calculate the outer radius of the H/alpha emitting region as 10.4 +/-0.5 Rsun and the accretion rate as 1.8 x 10 E-7 Msun/yr.

description: Angiotensin-converting enzyme 2 (ACE2), part of the renin-angiotensin system (RAS), serves as an entry point for SARS-CoV-2, leading to viral proliferation in permissive cell types. Using mouse lines in which the Ace2 locus has been humanized by syntenic replacement, we show that regulation of basal and interferon induced ACE2 expression, relative expression levels of different ACE2 transcripts, and sexual dimorphism in ACE2 expression are unique to each species, differ between tissues, and are determined by both intragenic and upstream promoter elements. Our results indicate that the higher levels of expression of ACE2 observed in the lungs of mice relative to humans may reflect the fact that the mouse promoter drives expression of ACE2 in populous airway club cells while the human promoter drives expression in alveolar type 2 (AT2) cells. In contrast to transgenic mice in which human ACE2 is expressed in ciliated cells under the control of the human FOXJ1 promoter, mice expressing ACE2 in club cells under the control of the endogenous Ace2 promoter show a robust immune response after infection with SARS-CoV-2, leading to rapid clearance of the virus. This supports a model in which differential expression of ACE2 determines which cell types in the lung are infected, and this in turn modulates the host response and outcome of COVID-19.

description: Context. CARMENES is a stabilised, high-resolution, double-channel spectrograph at the 3.5 m Calar Alto telescope. It is optimally designed for radial-velocity surveys of M dwarfs with potentially habitable Earth-mass planets. Aims. We prepare a list of the brightest, single M dwarfs in each spectral subtype observable from the northern hemisphere, from which we will select the best planet-hunting targets for CARMENES. Methods. In this first paper on the preparation of our input catalogue, we compiled a large amount of public data and collected low-resolution optical spectroscopy with CAFOS at the 2.2 m Calar Alto telescope for 753 stars. We derived accurate spectral types using a dense grid of standard stars, a double least-squares minimisation technique, and 31 spectral indices previously defined by other authors. Additionally, we quantified surface gravity, metallicity, and chromospheric activity for all the stars in our sample. Results. We calculated spectral types for all 753 stars, of which 305 are new and 448 are revised. We measured pseudo-equivalent widths of Halpha for all the stars in our sample, concluded that chromospheric activity does not affect spectral typing from our indices, and tabulated 49 stars that had been reported to be young stars in open clusters, moving groups, and stellar associations. Of the 753 stars, two are new subdwarf candidates, three are T Tauri stars, 25 are giants, 44 are K dwarfs, and 679 are M dwarfs. Many of the 261 investigated dwarfs in the range M4.0-8.0 V are among the brightest stars known in their spectral subtype. Conclusions. This collection of low-resolution spectroscopic data serves as a candidate target list for the CARMENES survey and can be highly valuable for other radial-velocity surveys of M dwarfs and for studies of cool dwarfs in the solar neighbourhood.

Fire frequency and vulnerability in California

Publisher: name: Public Library of Science
Year: 2023

description: Wildfires pose a large and growing threat to communities across California, and understanding fire vulnerability and impacts can enable more effective risk management. Government hazard maps are often used to identify at-risk areas, but hazard zones and fire experience may have different implications for communities. This analysis of three decades of fire footprints, hazard maps, and census and real estate data shows that communities with high fire experience differ substantially from communities with high fire hazard. High-hazard communities average higher incomes than low- and no-hazard communities; conversely, communities with high fire experience average lower incomes than those with little to no experience. Home values have grown more slowly in communities with high fire experience, translating to differences in total appreciation of $165M-$630M per year relative to communities with no fire experience. Warming over the remainder of the century could add tens of thousands of homes to high-experience zones. This relationship between income and fire experience may be a reflection of the impacts of repeated fires relative to mapped hazards or single fires, or it could point to a relationship between income and the success of fire prevention or suppression. The discrepancies between dimensions indicates that considering fire frequency can support efforts to equitably target risk management resources.

description: We show that the observed rotation curves of spiral galaxies constrain the sound speed of the dark matter to be $c_s < 10^{-4} c$, where $c$ is the speed of light in vacuum. Using the Modified Chaplygin Gas as a representative example of a class of unified dark energy models incorporating an effective dark matter component with a non-zero sound speed, we determine the most stringent constraint to date on the value of the constant contribution to the equation of state parameter in this class of models. Finally, we explain the reason why previous constraints using the Cosmic Microwave Background and Baryonic Acoustic Oscillations were not as competitive as the one presented in this paper and discuss the limitations of the recently proposed Extended Chaplygin Gas.

description: We study the dynamics of the entanglement in one dimensional critical quantum systems after a local quench in which two independently thermalized semi-infinite halves are joined to form a homogeneous infinite system and left to evolve unitarily. We show that under certain conditions a nonequilibrium steady state (NESS) is reached instantaneously as soon as the entanglement interval is within the light-cone emanating from the contact point. In this steady state, the exact expressions for the entanglement entropy and the logarithmic negativity are in agreement with the steady state density matrix being a boosted thermal state, as expected. We derive various general identities: relating the negativity after the quench with unequal left and right initial temperatures, with that with equal left and right temperatures; and relating these with the negativity in equilibrium thermal states. In certain regimes the resulting expressions can be analytically evaluated. Immediately after the interval interesects the lightcone, we find logarithmic growth. For a very long interval, we find that the negativity approaches a plateau after sufficiently long times, different from its NESS value. This provides a theoretical framework explaining recently obtained numerical results.

description: This essay argues that rule-of-law culture could be an avenue of research to address the issue of constitutional resilience of liberal democratic regimes, i.e. the capacity of liberal constitution to resist the passage of time and to remain legitimate in the eyes of the citizenry. Firstly, I use Rawls’ definition of originating and joining consent and Easton’s work on diffuse and specific support to explain how constitutions must activate specific mechanisms of support to resist the passage of time. I believe that rule-of-law culture could be a central mechanism. Secondly, I provide an account for a conceptualisation of rule-of-law culture. I identify three dimensions: between citizens, between institutions and between citizens and institutions. I then subdivide rule-of-law-culture in three components: constitutional consciousness, rule-of-law consciousness, and rights consciousness. Thirdly, I explain how direct experience and socialisation can contribute to the strengthening of rule-of-law culture. Keywords: rule-of-law culture; constitutional resilience; political support; legitimacy of constitutions

description: Background Relationships between the constructs of concussion-related knowledge, attitudes, and norms and their influence on observed care-seeking behaviors have previously been examined. Current models posit that these constructs serve as potential mediators of care-seeking behaviors; however, the dynamics between them have yet to be reconciled. Methods A cross-sectional, online survey explored relationships among the latent constructs of concussion-related knowledge, attitudes, and norms in parents of middle school children who participate in sports in multiple settings. A just-identified and two overidentified path models were explored and compared in an effort to understand such relationships. Results A total of 426 parents of United States middle school students were surveyed and included in analyses (mean age = 38.7±9.9 years; 55.6% female; 51.4% white/non-Hispanic; 56.1% with at least a bachelor’s degree). All parents had middle school aged children who participated in sport in both the club and school settings. The best fitting model was a just-identified model with concussion-related norms influencing concussion-related knowledge and attitudes, and concussion-related knowledge influencing attitudes. This model accounted for 14% of the variance in attitude and 12% of the variance in knowledge. Conclusions Study findings suggest that the constructs of concussion-related knowledge, attitudes and norms are directly related to one another, yet the dynamics of such relationships may be complex. As such, a parsimonious interpretation of these constructs may not be appropriate. Future research should work to further reconcile the dynamics between these constructs, and the impact these dynamics may have in influencing care-seeking behaviors beyond serving as mediators.

The common property of these models is the presence of the global variables. We discuss the meaning of these global variables in the context of the canonical formalism and argue that their presence lead to the non-local form of the Hamiltonian constraint.

description: Clinical performance status is designed to be a measure of overall health, reflecting a patient’s physiological reserve and ability to tolerate various forms of therapy. Currently, it is measured by a combination of subjective clinician assessment and patient-reported exercise tolerance in the context of daily living activities. In this study, we assess the feasibility of combining objective data sources and patient-generated health data (PGHD) to improve the accuracy of performance status assessment during routine cancer care. Patients undergoing routine chemotherapy for solid tumors, routine chemotherapy for hematologic malignancies, or hematopoietic stem cell transplant (HCT) at one of four sites in a cancer clinical trials cooperative group were consented to a six-week prospective observational clinical trial (NCT02786628). Baseline data acquisition included cardiopulmonary exercise testing (CPET) and a six-minute walk test (6MWT). Weekly PGHD included patient-reported physical function and symptom burden. Continuous data capture included use of a Fitbit Charge HR (sensor). Baseline CPET and 6MWT could only be obtained in 68% of study patients, suggesting low feasibility during routine cancer treatment. In contrast, 84% of patients had usable fitness tracker data, 93% completed baseline patient-reported surveys, and overall, 73% of patients had overlapping sensor and survey data that could be used for modeling. A linear model with repeated measures was constructed to predict the patient-reported physical function. Sensor-derived daily activity, sensor-derived median heart rate, and patient-reported symptom burden emerged as strong predictors of physical function (marginal R2 0.429–0.433, conditional R2 0.816–0.822).

description: The highly eccentric binary system Eta Carinae shows numerous time-variable emission and absorption features. These observational signatures are the result of interactions between the complex three-dimensional (3D) wind-wind collision regions and photoionization by the luminous stars. Specifically, helium presents several interesting spectral features that provide important clues on the geometry and physical properties of the system and the individual stars. We use the SimpleX algorithm to post-process 3D smoothed particle hydrodynamics simulation output of the interacting winds in Eta Car in order to obtain the fractions of ionized helium assuming three different primary star mass-loss rates. The resultant ionization maps constrain the regions where helium is singly- and doubly-ionized. We find that reducing the primary's mass-loss rate increases the volume of He+. Lowering the primary mass-loss rate produces large variations in the volume of He+ in the pre-shock primary wind on the periastron side of the system. Our results show that binary orientations in which apastron is on our side of the system are more consistent with available observations. We suggest that small variations in the primary's mass-loss rate might explain the observed increase in HeI absorption in recent decades, although numerous questions regarding this scenario remain open. We also propose that the absence of broad HeI lines in the spectra of Eta Car between its 1890's eruption and 1944 might be explained by the companion star's He0+ ionizing photons not being able to penetrate the wind-wind interaction region, due to a higher primary mass-loss rate at that time (by a factor >2, compared to the present value).

description: Recently, non-convex regularisation models have been introduced in order to provide a better prior for gradient distributions in real images. They are based on using concave energies $ϕ$ in the total variation type functional ${TV}^ϕ(u) := \int ϕ(|\nabla u(x)|) d x$. In this paper, it is demonstrated that for typical choices of $ϕ$, functionals of this type pose several difficulties when extended to the entire space of functions of bounded variation, ${BV}(Ω)$. In particular, if $ϕ(t)=t^q$ for $q \in (0, 1)$ and ${TV}^ϕ$ is defined directly for piecewise constant functions and extended via weak* lower semicontinuous envelopes to ${BV}(Ω)$, then still ${TV}^ϕ(u)=\infty$ for $u$ not piecewise constant. If, on the other hand, ${TV}^ϕ$ is defined analogously via continuously differentiable functions, then ${TV}^ϕ\equiv 0$, (!). We study a way to remedy the models through additional multiscale regularisation and area strict convergence, provided that the energy $ϕ(t)=t^q$ is linearised for high values. The fact, that this kind of energies actually better matches reality and improves reconstructions, is demonstrated by statistics and numerical experiments.

description: Due to high viscosity, glassy systems evolve slowly to the ordered state. Results of molecular dynamics simulation reveal that the structural ordering in glasses becomes observable over "experimental" (finite) time-scale for the range of phase diagram with high values of pressure. We show that the structural ordering in glasses at such conditions is initiated through the nucleation mechanism, and the mechanism spreads to the states at extremely deep levels of supercooling. We find that the scaled values of the nucleation time, $τ_1$ (average waiting time of the first nucleus with the critical size), in glassy systems as a function of the reduced temperature, $\widetilde{T}$, are collapsed onto a single line reproducible by the power-law dependence. This scaling is supported by the simulation results for the model glassy systems for a wide range of temperatures as well as by the experimental data for the stoichiometric glasses at the temperatures near the glass transition.

description: Protein kinases play a vital role in a wide range of cellular processes, and compounds that inhibit kinase activity emerging as a primary focus for targeted therapy development, especially in cancer. Consequently, efforts to characterize the behavior of kinases in response to inhibitor treatment, as well as downstream cellular responses, have been performed at increasingly large scales. Previous work with smaller datasets have used baseline profiling of cell lines and limited kinome profiling data to attempt to predict small molecule effects on cell viability, but these efforts did not use multi-dose kinase profiles and achieved low accuracy with very limited external validation. This work focuses on two large-scale primary data types, kinase inhibitor profiles and gene expression, to predict the results of cell viability screening. We describe the process by which we combined these data sets, examined their properties in relation to cell viability and finally developed a set of computational models that achieve a reasonably high prediction accuracy (R2 of 0.78 and RMSE of 0.154). Using these models, we identified a set of kinases, several of which are understudied, that are strongly influential in the cell viability prediction models. In addition, we also tested to see if a wider range of multiomics data sets could improve the model results and found that proteomic kinase inhibitor profiles were the single most informative data type. Finally, we validated a small subset of the model predictions in several triple-negative and HER2 positive breast cancer cell lines demonstrating that the model performs well with compounds and cell lines that were not included in the training data set. Overall, this result demonstrates that generic knowledge of the kinome is predictive of very specific cell phenotypes, and has the potential to be integrated into targeted therapy development pipelines.

description: This study contributes to the growing strand of research on the repercussions of the COVID-19 pandemic. The home confinement imposed as part of nationwide movement restrictions in many countries represents an exceptional setting for the study of intimate relationships. Did the lockdown reduce partnership quality? In this study, we present some descriptive findings based on a online survey conducted during the first phase of the COVID-19 pandemic in France, Italy and Spain. Around 12% of those interviewed in the three countries reported that their relationship with their partner had worsened during the lockdown and about 2.5% intended to split up. In addition, we show that negative emotions – such as feeling lonely – and deterioration of income/work conditions are associated with a worsening of partnership quality. In all, we suggest that the consequences of the COVID-19 pandemic are not only economic; couples and intimate relationships have been vulnerable, too.

description: Shining a tightly-focused but low-powered laser beam on an absorber dispersed in a biological fluid gives rise to spectacular growth of dendritic patterns. These result from localized drying of the fluid because of efficient absorption and conduction of optical energy by the absorber. We have carried out experiments in several biologically relevant fluids and have analyzed patterns generated by different types of absorbers. We observe that the growth velocity of branches in the dendritic patterns can decrease below the value expected for natural drying.

description: We consider real-valued solutions $u=u(x|s),x\in\mathbb{R}$ of the second Painlevé equation $u_{xx}=xu+2u^3$ which are parametrized in terms of the monodromy data $s\equiv(s_1,s_2,s_3)\subset\mathbb{C}^3$ of the associated Flaschka-Newell system of rational differential equations. Our analysis describes the transition, as $x\rightarrow-\infty$, between the oscillatory power-like decay asymptotics for $|s_1|<1$ (Ablowitz-Segur) to the power-like growth behavior for $|s_1|=1$ (Hastings-McLeod) and from the latter to the singular oscillatory power-like growth for $|s_1|>1$ (Kapaev). It is shown that the transition asymptotics are of Boutroux type, i.e. they are expressed in terms of Jacobi elliptic functions. As applications of our results we obtain asymptotics for the Airy kernel determinant $\det(I-γK_{\textnormal{Ai}})|_{L^2(x,\infty)}$ in a double scaling limit $x\rightarrow-\infty,γ\uparrow 1$ as well as asymptotics for the spectrum of $K_{\textnormal{Ai}}$.

description: We have studied the magnetic and superconducting properties of Ba(Fe$_{0.95}$Co$_{0.05}$)$_{2}$As$_{2}$ as a function of temperature and external magnetic field using neutron scattering and muon spin rotation. Below the superconducting transition temperature the magnetic and superconducting order parameters coexist and compete. A magnetic field can significantly enhance the magnetic scattering in the superconducting state, roughly doubling the Bragg intensity at 13.5 T. We perform a microscopic modelling of the data by use of a five-band Hamiltonian relevant to iron pnictides. In the superconducting state, vortices can slow down and freeze spin fluctuations locally. When such regions couple they result in a long-range ordered antiferromagnetic phase producing the enhanced magnetic elastic scattering in agreement with experiments.

description: Microbial communities in the rhizosphere influence nutrient acquisition and stress tolerance. How abiotic and biotic factors impact the plant microbiome in the wild has not been thoroughly addressed. We studied how plant genotype and soil affect the rhizosphere microbiome of Vaccinium floribundum, an endemic species of the Andean region that has not been domesticated or cultivated. Using high-throughput sequencing of the 16S rRNA and ITS region, we characterized 39 rhizosphere samples of V. floribundum from four plant genetic clusters in two soil regions from the Ecuadorian Highlands. Our results showed that Proteobacteria and Acidobacteria were the most abundant bacterial phyla and that fungal communities were not dominated by any specific taxa. Soil region was the main predictor for bacterial alpha diversity, phosphorous and lead being the most interesting edaphic factors explaining this diversity. The interaction of plant genotype and altitude was the most significant factor associated with fungal diversity. This study highlights how different factors govern the assembly of the rhizosphere microbiome of a wild plant. Bacterial communities depend more on the soil and its mineral content, while plant genetics influence the fungal community makeup. Our work illustrates plant–microbe associations and the drivers of their variation in a unique unexplored ecosystem from the Ecuadorian Andes.

description: Globally to date, established international standards for animal welfare, a priority of sustainable agriculture, have primarily focused on large-scale producers. However, across Latin America, including in Ecuador’s Galápagos Islands, smallholder farms play a critical role in food safety and security. We assessed five basic animal welfare measures (feed and water access, shelter availability and housing systems, animal health management, animal behavior, and timely euthanasia) for poultry, pigs, and cattle on Floreana Island, Galápagos. Utilizing assessment standards from multiple US sources and international standards, we developed a questionnaire and used it to conduct in-depth interviews during 4–5 July 2022 with eight participating producers, representing 75% of animal agriculture on Floreana. While we identified opportunities to enhance competencies in animal health management and timely euthanasia, farms performed well in the other assessed measures. Future work should promote knowledge transfer and in-country capacity building in farm biosecurity, access to veterinary care, antimicrobial resistance surveillance, and euthanasia methods. Efforts to positively impact smallholder farm livelihoods in Galápagos—one of the most biodiverse and protected ecosystems on the planet—will sustainably support human health through the interconnected realms of animal health and welfare, wildlife and environmental health, and food safety and security.

description: We investigate the survival of circularly polarized light in random scattering media. The surprising persistence of this form of polarization has a known dependence on the size and refractive index of scattering particles, however a general description regarding polydisperse media is lacking. Through analysis of Mie theory, we present a means of calculating the magnitude of circular polarization memory in complex media, with total generality in the distribution of particle sizes and refractive indices. Quantification of this memory effect enables an alternate pathway towards recovering particle size distribution, based on measurements of diffusing circularly polarized light.

description: Successful delivery of IT projects is a growing concern among most IT vendors. Despite the availability of the right resources and budget still many IT projects overrun their stipulated time and budget. It has been estimated that on an average 80% of the projects encounter some type of issue either in terms of time overrun, project budget overrun or reduced success rate. This dissertation focuses on ways to assess the pitfalls faced in Artificial Intelligence (AI) based project implementation in general and more specific to Multi Agent System (MAS), their remedies and the right mix of the solution to deliver the IT project on time and within budget This research expects to produce a number of key findings: a) historical evidences to confirm a significant increase in the complexity in developing MAS projects b) the different types of methodologies used in recent years to resolve such complexities, systematic practical approaches in reaching the project targets supported by facts and figures, and c) case studies and examples; a global solution to address the common problems in MAS project implementation.
