description: IRAS04325+2402 (herafter IRAS04325) is a complex protostellar system hosting two young stellar objects (AB and C in the following) at a separation of 1250AU. Here we present new deep Gemini imaging and spectroscopy for the system covering the wavelength regime from 1-12mu as well as Sub-Millimeter Array interferometry at 870mu, in combination with Spitzer and literature data. Object AB is a low-mass star with a disk/envelope system and an outflow cavity, which is prominently seen in infrared images. Object C, previously suspected to be a brown dwarf, is likely a very low mass star, with an effective temperature of ~3400K. It features an edge-on disk and an elongated envelope, and shows strong indications for accretion and ejection activity. Both objects are likely to drive parsec-scale molecular outflows. The two objects are embedded in an isolated, dense molecular cloud core. High extinction, lack of X-ray emission, and relatively high bolometric luminosity argue for a very young age below 1Myr. The disk/outflow systems of AB and C are misaligned by ~60deg against each other and by 80 and 40deg against the orbital plane of the binary. The system might be a good case for primordial misalignment, as opposed to misalignment caused by dynamical interactions, because the outflow direction is constant and the realignment timescale is likely larger than the system age. This favours turbulent fragmentation, rather than rotational fragmentation, as the formation scenario. We show that the spectral energy distributions and images for the two objects can be reproduced with radiative transfer models for disk/envelope systems. Our analysis provides reassurance in the established paradigm for the structure and early evolution of YSOs, but stresses the importance of developing 3D models with sophisticated dust chemistry (abridged).

Exploration of factors that influence heterogeneous ice nucleation : laboratory experiments and molecular dynamics simulations
Creators: name: Ren, Yi
Publisher: name: University of British Columbia

description: Pure water does not freeze homogeneously at temperatures above -35°C. Heterogeneous ice nucleation induced by ice nucleating particles (INPs) occurs at warmer temperatures than homogeneous nucleation. Atmospherically relevant INPs can significantly affect ice formation in mixed-phase and ice clouds, and therefore influence the Earth’s climate system. Several factors, including inorganic ions, acidic or basic solutes, and pressure variations influence the ice nucleating ability of INPs. At present, little is known about the microscopic mechanisms by which these factors affect heterogeneous ice nucleation and the ice nucleating ability of INPs. We examine the influences of inorganic ions and pH changes on kaolinite’s ice nucleating ability employing direct molecular dynamics (MD) simulations. We demonstrate that ionic solutes decrease the ice nucleating ability of the Al (001) kaolinite surface. The hydroxy groups exposed on the Al (001) surface can become deprotonated in basic solution or dual-protonated in acidic solution. We find that the mono-protonated Al (001) surface, which is expected to be stable at near-neutral pH, is the most effective ice nucleating surface. We perform droplet freezing experiments with kaolinite samples under acidic and basic conditions, covering a pH range of 0.18 - 13.26. Our MD simulations and experimental results indicate that the Al (001) surface may be important for ice nucleation by kaolinite. Employing MD simulations and varying the protonation state of the α-alumina (0001) surface, we find that the ice nucleating efficiency of this surface decreases nearly symmetrically with acidic and basic pH changes away from the neutral point. This is in qualitative agreement with previous droplet freezing experiments performed on a single (0001) surface. We carry out droplet freezing experiments on two α-alumina powder samples, covering a pH range of 0.59 - 13.19. The freezing results for the powder differ significantly from those of the single surface. We use MD simulations to probe the influence of pressure on heterogeneous ice nucleation by a finite-size β-AgI disk. We find that negative pressures enhance ice nucleation at high temperature, and we demonstrate how water diffusion can significantly influence ice nucleation and growth at low temperatures and negative pressures.

description:
In addition to its importance for basic scientific research, Citizen Science involving micrometeorites collected from the roofs of Berlin has a special potential for promoting scientific literacy and the understanding of science in general (Hecht et al. 2021). Yet, Citizen Science still occurs too rarely in schools and requires further development (GEWISS 2016). Moreover, earth sciences are only briefly addressed in school curricula. The Citizen Science approach can be applied very well to the Berlin framework curriculum due to its many links to geography, physics and chemistry lessons. Citizen Science can be an important part of geoscience or natural science education and even contribute to strengthening democratic participation and research (Burger 2016).

This project aims to develop and test a Citizen Science approach in a school setting. In cooperation with grade 9 students in a Berlin high school, we are conducting sampling and scientific processing of micrometeorites from a Berlin roof using almost all essential research steps. The project’s main setting is at school. In order to enable active participation in the use of large-scale equipment, we will test the remote control of such equipment by students in the classroom.

description: We use a nonstationary generalization of the higher-order structure function technique to investigate statistical properties of the magnetic field fluctuations recorded by MESSENGER spacecraft during its first flyby (01/14/2008) through the near Mercury's space environment, with the emphasis on key boundary regions participating in the solar wind -- magnetosphere interaction. Our analysis shows, for the first time, that kinetic-scale fluctuations play a significant role in the Mercury's magnetosphere up to the largest resolvable time scale ~20 s imposed by the signal nonstationarity, suggesting that turbulence at this planet is largely controlled by finite Larmor radius effects. In particular, we report the presence of a highly turbulent and extended foreshock system filled with packets of ULF oscillations, broad-band intermittent fluctuations in the magnetosheath, ion-kinetic turbulence in the central plasma sheet of Mercury's magnetotail, and kinetic-scale fluctuations in the inner current sheet encountered at the outbound (dawn-side) magnetopause. Overall, our measurements indicate that the Hermean magnetosphere, as well as the surrounding region, are strongly affected by non-MHD effects introduced by finite sizes of cyclotron orbits of the constituting ion species. Physical mechanisms of these effects and their potentially critical impact on the structure and dynamics of Mercury's magnetic field remain to be understood.

description:
One of the limits of planetary habitability of Earth and other water-rich planets relates to the instability with respect to global glaciation, a fundamental property of the climate system caused by the positive ice-albedo feedback. Due to the steady increase in solar luminosity, the atmospheric concentration of carbon dioxide (CO2) at which this Snowball bifurcation occurs evolves over time. Earlier studies on the limit of global glaciation are based on investigations with very simple climate models for Earth’s entire history or studies of individual time slices carried out with a variety of more complex models and for different boundary conditions, making comparisons difficult. Here we use a relatively fast coupled climate model of intermediate complexity to trace the Snowball bifurcation of an aquaplanet through Earth’s history in one consistent modelling framework. We find that the critical CO2 concentration decreases more or less logarithmically with increasing solar luminosity until about 1 billion years ago, but drops faster in more recent times. Furthermore, there is a fundamental shift in the dynamics of the critical state about 1.8 billion years ago, driven by the interplay of wind-driven sea-ice dynamics and the surface energy balance. These results highlight once again the importance of climate dynamics for investigations of planetary habitability.

title: Imbalances in dissolved elemental export fluxes disclose “hidden” Critical Zone pathways

description:
Streams are integrators over all biogeochemical reactions taking place in the Critical Zone. The resulting export of dissolved elements from a watershed is commonly used to infer chemical weathering fluxes. Yet, this approach rests on the assumption that the mass of a given element released from primary minerals that was not incorporated into secondary solids is quantitatively transferred into the stream in the dissolved form. The comparison of element-specific solute stream fluxes with chemical weathering fluxes determined in the residual solids shows that this is often not the case. An imbalance persists even after correcting for a bias potentially introduced by changes in water flow over these entirely different timescales.

To explore causes for imbalances between short-term and long-term weathering fluxes, described by their ratio in form of a “Dissolved Export Efficiency” (DEE), we sampled six Critical Zone water compartments for one year in the Conventwald (Black Forest, Germany). We found deficits in the dissolved load, which emerged in the deep saprolite. For Si, Al, and Fe the deficit can be attributed to an export pathway that includes a “hidden” Critical Zone compartment or pool of unsampled colloids that are exported preferentially during flushing events. In contrast, deficits found for nutritive elements (Ca, K, Mg, P) can be explained by deep nutrient uptake followed by nutrient retainment in re-growing forest biomass or export in form of biogenic particulates. Given the collective evidence for these imbalances the deep Critical Zone warrants attention towards a complete budget of element cycles.

Hence it is a pure point measure whose support is the full interval [-1; +1]. The space of paperfolding sequences has an ultrametric structure.

description:
Dehydration of oceanic lithosphere during subduction is a key process in the Earth's deep volatile cycle. Field observations and studies of obducted meta-serpentinites that underwent dehydration at depth often show an interconnected, channelized vein network that formed during dehydration and served as pathway for fluid release from the dehydrating rock. Previous studies show that chemical heterogeneities in the bulk-rock composition lead to channelization of fluid flow from the onset of the dehydration process and how subsequent reactive fluid flow in the porous network causes further dehydration and channelization. On larger scales, fluid release from the rock is governed by mechanical processes such as porosity waves. While the micro- and meso-scale have been studied so far, this large-scale fluid release mechanism has not yet been explored for dehydrating serpentinite.

Here, we present a model for reactive porosity waves that investigates the large-scale fluid release from a dehydrating serpentinite. The model combines viscous rheology with the transport of dissolved silica in the fluid which has been shown to be a key metasomatic agent in the dehydration process. As input for our model, we use a multi-scale dataset of fully hydrated serpentinite from an ophiolite taken as representative for serpentinized oceanic lithosphere entering a subduction zone. We use the data to explore the formation of the vein network during dehydration and the behavior during large-scale fluid escape by reactive porosity waves.

Oral Corrective Feedback

description: This mixed-methods project was designed to answer four questions around the quality of oral production of French Immersion students: How does the nature of the interactions between intermediate-level FI students provide possibilities for them to engage in peer oral corrective feedback (OCF)? To what extent do students engage in peer OCF following targeted instruction in the technique? If peer OCF is taking place, to what extent is it having an impact on the accuracy of the targeted forms for correctors and correctees in terms of noticing and production? How comfortable (or willing) are students with providing and receiving OCF to and from their peers (both higher & lower proficiency)? A pre- & post-test, and questionnaire, format was used, and detailed analysis of participants in L2 interaction was carried out. The results indicated that the target structures and the OCF techniques may have been too cumbersome to elicit any improvement, or to elicit much peer OCF. However the conversation analysis indicated that in certain circumstances intermediate FI students could participate in sustained L2 interaction, and that within their interactions there were many openings for other forms of active assistance between learners.

description: A few examples are given of Chandra's work on statistical and stochastic problems that relate to open questions in astrophysics, in particular his theory of dynamical relaxation in systems with inverse-square interparticle forces. The roles of chaos and integrability in this theory require clarification, especially for systems having a dominant central mass. After this prelude, a hypothetical form of repulsive bosonic dark matter is discussed. The repulsion leads to nontrivial thermodynamic behavior, including superfluidity, and would tend to suppress dynamical friction, greatly reducing the drag exerted on rotating galactic bars. However, this form of dark matter can probably be ruled out, at least for parameters that allow halos to reach thermal equilibria within a Hubble time. One combination of the particle mass and interparticle repulsion determines the minimum core radius of dark halos. Bounds on dark-matter collisionality inferred from the Bullet Cluster constrain a second combination. It is possible to satisfy both constraints only for parameters that predict unacceptable rotation curves outside the halo core.

New Developments on Bayesian Bootstrap for Unrestricted and Restricted Distributions

Chi-squared test

description: The recent popularity of Bayesian inference is due to the practical advantages of the Bayesian approach. The Bayesian analysis makes it possible to reflect ones prior beliefs into the analysis. In this thesis, we explore some asymptotic results in Bayesian nonparametric inference for restricted and unrestricted space of distributions. This thesis is divided into two parts. In the first part, we employ the Dirichlet process in a hypothesis testing framework to propose a Bayesian nonparametric chi-squared goodness-of-fit test. Our suggested method corresponds to Lo's Bayesian bootstrap procedure for chi-squared goodness-of-fit test. Indeed, our bootstrap rectifies some shortcomings of regular bootstrap which only counts number of observations falling in each bin in contingency tables. We consider the Dirichlet process as the prior for the distribution of data and carry out the test based on the Kullback-Leibler distance between the Dirichlet process posterior and the hypothesized distribution. We prove that this distance asymptotically converges to the same chi-squared distribution as the classical frequentist's chi-squared test. Moreover, the results are generalized to the chi-squared test of independence for contingency tables. In the second part, our main focus is on Bayesian nonparametric inference for a restricted group of distributions called spherically symmetric distributions. We describe a Bayesian nonparametric approach to perform an inference for a bivariate spherically symmetric distribution. We place a Dirichlet invariant process prior on the set of all bivariate spherically symmetric distributions and derive the Dirichlet invariant process posterior. Indeed, our approach is an extension of the Dirichlet invariant process for the symmetric distributions on the real line to bivariate spherically symmetric distribution where the underlying distribution is invariant under a finite group of rotations. Further, we obtain the Dirichlet invariant process posterior for the infinite transformation group and we prove that it approaches a certain Dirichlet process. Finally, we develop our approach to obtain the Bayesian nonparametric posterior distribution for functionals of the distribution's support when the support satisfies certain symmetry conditions. When symmetry holds with respect to the parallel lines of axes (for example, in two dimensional space x = a and y = b) we employ our approach to approximate the distribution of certain functionals such as area and perimeter for the support of the distribution. This suggests a Bayesian nonparametric bootstrapping scheme. The estimates can be derived based on posterior averaging. Then, our simulation results demonstrate that our suggested bootstrapping technique improves the accuracy of the estimates.

Year: 2023

description:
Petalite was the first mineral in which lithium was detected, but its economic importance is less than that of the lithium-rich spodumene. Both minerals occur in pegmatitic deposits (LCT pegmatites), which were explored in the past mainly for tin and tantalum. Nowadays, lithium-bearing minerals are the focus of mining. Although both minerals are similar in the processing and extraction of lithium, their mineralogical properties differ. Through roasting, petalite undergoes a phase transformation to β-spodumene, producing quartz as an excess. Subsequently, the roasted material can be fed into the established converter process to produce lithium hydroxide or lithium carbonate.

In order to cover the increasing demand for lithium for use in lithium-ion batteries as a contribution to the energy transition and the associated turn away from fossil fuels, investments in mining projects away from the particularly lucrative spodumene pegmatites are necessary. Petalite is one such alternative.

Using petalite deposits in Namibia as an example, we will show whether it is possible to determine the mine of origin based on mineralogical and geochemical properties to contribute to possible lithium fingerprinting as proof of origin. The approach is based on the combination of different analytical methods, such as EDX, electron microprobe and trace element distribution using ICP-MS. Lithium fingerprinting can then be used as a tool for material-based control of ESG criteria upstream in the lithium value chain.

H2 production monitoring with time and characterization of the reaction products revealed the occurrence of the following reaction: 3 Fe(OH)2brucite = Fe3O4 + H2 + 2 H2O. This reaction proceeded completely in ~ 2 months at 378 K and was thermally activated. The small grain size of the synthetic brucite (40-100 nm) was similar to observations in natural samples, and was probably responsible for the high reaction rate measured. H2 production reached a plateau and Fe-bearing brucite also precipitated as a reaction product, suggesting the achievement of equilibrium. The thermodynamic properties of Fe(OH)2 were refined based on the experimental dataset and differ by less than 5 % from previous estimates. However, ferroan brucite is predicted to be stable at an hydrogen activity one order of magnitude lower than previously calculated. As a result, significant H2 production during ferroan brucite alteration at low temperature requires efficient fluid renewal. Such a mechanism strongly differs from olivine serpentinization which can occur even at high activity in H2 and thus with limited water renewal.

description: The brightest and most surprising feature in the first all-sky maps of Energetic Neutral Atoms (ENA) emissions (0.2-6 keV) produced by the Interstellar Boundary Explorer (IBEX) is an almost circular ribbon of a ~140° opening angle, centered at (l,b) = (33°, 55°), covering the part of the celestial sphere with the lowest column densities of the Local Interstellar Cloud (LIC). We propose a novel interpretation of the IBEX results based on the idea of ENA produced by charge-exchange between the neutral H atoms at the nearby edge of the LIC and the hot protons of the Local Bubble (LB). These ENAs can reach the Sun's vicinity because of very low column density of the intervening LIC material. We show that a plane-parallel or slightly curved interface layer of contact between the LIC H atoms (n_H = 0.2 cm^-3, T = 6000-7000 K) and the LB protons (n_p = 0.005 cm^-3, T ~ 10^6 K), together with indirect contribution coming from multiply-scattered ENAs from the LB, may be able to explain both the shape of the ribbon and the observed intensities provided that the edge is < (500-2000) AU away, the LIC proton density is (correspondingly) < (0.04-0.01) cm^-3, and the LB contains ~1% of non-thermal protons over the IBEX energy range. If this model is correct, then IBEX, for the first time, has imaged in ENAs a celestial object from beyond the confines of the heliosphere and can directly diagnose the plasma conditions in the LB.

description: The purpose of this study is to explore Black Canadian English language learning students’ acquisition and use of Black Stylised English. I will be looking at the use of Black Stylised English with respect to these students’ experiences of racial microaggressions, defined as everyday subtle acts of racism. This study poses the question: How does experiencing racial microaggression impact Black Canadian ELL students’ acquisition of Black English as a second language? This study was conducted in 2015 and draws on Critical Race Theory methodology with a focus on storytelling and counter-storytelling as a means to disrupt the dominant narrative. The participants were Black Canadian ELL students from immigrant families living in a metropolitan city in Northeastern Ontario attending after-school programs. A purposefully selected sample of 24 students who self-identified as Black and four support workers were examined. Data for this study was collected at three different after-school program sites. The first after-school program was located in a suburb at a seniors’ residence where students volunteered. The second after-school program was located in the downtown area and catered to newly arrived immigrants. The third site was located in the west end of the city and focused on the academic success of students from low-income families. The study found the following: first, all participants had experienced racial microaggressions. Second, there are similarities and differences in the participants’ experiences depending on the context. Third, experiencing racial microaggressions had an emotional effect on participants. Fourth, most participants did not know how to respond directly to racial microaggressions. Fifth, although they did not know how to respond to racial microaggressions, the boy participants used Black Stylized English as a defence mechanism to cope with the racial microaggressions. The girl participants acquired and used BSE to fit-in with other Black girls. In response to racial microaggressions the girl participants focused on losing their accents in order fit-in with their racialized White counterparts. Sixth, after-school programs operate on the basis of the authorized multicultural discourse.

description:
Reflection seismics is the most common geophysical method for obtaining structural images of the subsurface. It can image subsurface structures over large areas and depth ranges at high resolution. In order to make a reliable assessment of seismic imaging results, e.g. to quantify uncertainties, it is important to understand the concepts of seismic resolution. At brief, seismic resolution is the ability to distinguish between two seismic features from one another and resolve them separately.

Theoretical considerations to seismic resolution criteria and their implications for seismic imaging are discussed in many textbooks, but the practical use in interpretation is often difficult to achieve. This is, because the underlying parameters, e.g. the bandwidth and the velocity of the seismic signal, are not explicitly visible on the final stacked image, especially if the sections are depth converted.

However, the measure for vertical resolution is the dominant wavelength and the resolution criteria is expressed as a fraction of it, e.g. λ/4 criterion, whereas a measure of the lateral resolution is the Fresnel zone. Both of which can be computed by common functions that are available in most interpretation systems. As a result, seismic sections showing the spatial variability of both vertical and horizontal resolution are obtained that can be blended into the stacked seismic section. This gives a tool at hand – just like a seismic attribute – to estimate the limits of seismic resolution and access uncertainties in the final seismic image.

description:
Subducted oceanic crust plays an important role in controlling the chemical budget of the crust and mantle and in the composition of arc lavas. Oceanic eclogites represent fragments of oceanic crust that have been through a subduction zone and were subsequently exhumed and exposed. A range of geochemical signatures in oceanic eclogites have been studied to unravel the fluid-rock interaction processes. A key tracer is the trace-element boron and its isotope ratio (11B/10B) in oceanic eclogites with its great potential for quantifying mass transfer processes at convergent margins. Current models predict a strong decrease of δ11B values in the subducting crust with progressive dehydration to values much below that of the depleted mantle (appr. -7 ‰).

We have analyzed elemental abundances and boron isotopic compositions of oceanic metamorphic rocks, from Zambezi Belt, Cabo Ortegal complex, Raspas Complex, Syros Island, and Tian Shan. Whole-rock B/Pr ratios were used to quantify the progress of dehydration. The boron isotopic composition of almost all samples (approximately -10 to +5 ‰) ranges from δ11B values close to that of fresh MORB to that of typical altered oceanic crust. Also, the sample set shows no correlation between δ11B values and B/Pr, as would be expected from current theoretical models. Our results, thus, demonstrate that B isotopic fractionation in subducted oceanic crust is much smaller than predicted. We suggest that this discrepancy can be resolved by accepting high pH values in high-pressure hydrous fluids, which show a much smaller boron isotope fractionation in equilibrium with B-bearing silicates.

description: Statistical behavior and scaling properties of iso-height lines in three different saturated two-dimensional grown surfaces with controversial universality classes are investigated using ideas from Schramm-Loewner evolution (SLE$_κ$). We present some evidence that the iso-height lines in the ballistic deposition (BD), Eden and restricted solid-on-solid (RSOS) models have conformally invariant properties all in the same universality class as the self-avoiding random walk (SAW), equivalently SLE$_{8/3}$. This leads to the conclusion that all these discrete growth models fall into the same universality class as the Kardar-Parisi-Zhang (KPZ) equation in two dimensions.

description:
Zn-Pb deposits are host to a large proportion of worldwide resources of Ge and other critical metals. The Black Angel district in central West Greenland hosts several Zn-Pb occurrences, including the historic Black Angel mine, South Lakes and Kangerluarsuk, that show a previously unrecognized endowment of Ge and Bi (± Te) respectively. The carbonate-hosted MVT deposits at Black Angel and South Lakes show strong deformation and associated ore remobilisation at Upper Greenschist facies conditions (ca. 470°C), as indicated by graphite thermometry. Germanium occurs in tectonised and remobilised ore in the form of briartite, which is hosted in sphalerite and galena matrix. We studied how rock deformation and related remobilisation processes in these ore bodies lead to the redistribution of Ge and formation of briartite. Germanium was most likely exsolved from sphalerite as nanoinclusions of briartite during recrystallisation. Subsequent solid-state and fluid-assisted processes lead to formation of micrometre sized grains of briartite in sphalerite matrix, as well as up to millimetre-sized briartite aggregates. However, the nearby clastic-hosted SEDEX deposit at Kangerluarsuk shows native bismuth and tellurides hosted with galena, and no briartite or other Ge enrichment. Thus, two contrasting Zn-Pb systems with a different critical metal endowment are in close proximity to one another.

description: Terahertz time domain spectroscopy has been used to study low frequency confined acoustic phonons of silver nanoparticles embedded in poly(vinyl alcohol) matrix in the spectral range of 0.1 to 2.5 THz. The real and imaginary parts of the dielectric function show two bands at 0.60 THz and 2.12 THz attributed to the spheroidal and toroidal modes of silver nanoparticles, thus demonstrating the usefulness of terahertz time domain spectroscopy as a complementary technique to Raman spectroscopy in characterizing the nanoparticles.
