A microanalytical investigation of feldspars in the Skaergaard intrusion, East Greenland : ternary feldspar compositional relations and lead isotopic geochemistry
Creators: name: Cho, June On Yee
Publisher: name: University of British Columbia
Year: 2019

description: The Eocene Skaergaard intrusion, part of the East Greenland flood basalt province, is the type example of closed-system differentiation of basaltic magma. Studies of this remarkable layered intrusion have profoundly influenced our understanding of fundamental petrologic concepts. In this study, two complementary microanalytical applications of feldspar geochemistry are used to compare and evaluate (1) differentiation processes preserved in primocryst and interstitial feldspar, (2) the validity of the closed-system model for crystallization of the Skaergaard magma, and (3) the genetic link between the Skaergaard intrusion and the age-specific interval of the contemporaneous flood basalts. The spatially-controlled analyses include measurements of major and minor element oxide contents by electron microprobe and of lead (Pb) isotope ratios by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). The major element results (>2600 analyses) span nearly the entire range of permissible ternary feldspar compositions, revealing the diverse range of processes that operated in the crystal mush. These compositions include calcic plagioclase in reactive symplectites, intermediate-composition plagioclase primocrysts with different zoning patterns that track fractionation of the resident magma, exsolved alkali feldpsars in interstitial granophyres produced during silicate liquid immiscibility, and replacement albite formed as a result of meteoric fluid circulation and subsequent alteration. The Pb isotopic results (>750 analyses) demonstrate that most of the Skaergaard intrusion has the same Pb isotope composition within analytical uncertainty and confirm that crystallization occurred under essentially closed-system conditions. Only minor incorporation (<1%) of crustal materials is detectable in select hybrid rocks from the outermost margins. The Pb isotope signature of the Skaergaard parental magma, represented by the average Layered Series, is more radiogenic than most of the flood basalts. This indicates prior assimilation of granulitic gneisses at depth and links the Skaergaard intrusion to the eruption of the Milne Land Formation, the lowermost and earliest of the voluminous and widespread 56-54 Ma flood basalts. This integrated microanalytical study of feldspar from the Skaergaard intrusion provides new tools and avenues for petrologic research that can be applied to investigating the origin and evolution of mafic layered intrusions and other feldspar-bearing plutonic rocks in the Earth’s crust.

description: There is a growing interest in very long baseline neutrino oscillation experimentation using accelerator produced neutrino beam as a machinery to probe the last three unmeasured neutrino oscillation parameters: the mixing angle theta_13, the possible CP violating phase delta_CP and the mass hierarchy, namely, the sign of delta-m^2_32. Water Cherenkov detectors such as IMB, Kamiokande and Super-Kamiokande have shown to be very successful at detecting neutrino interactions. Scaling up this technology may continue to provide the required performance for the next generation of experiments. This report presents the latest effort to demonstrate that a next generation (> 100 kton) water Cherenkov detector can be used effectively for the rather difficult task of detecting nu_e events from the neutrino oscillation nu_mu -> nu_e despite the large expected potential background resulting from pi^0 events produced via neutral current interactions.

Cerebral Cortical Networking for Mental Workload Assessment during Practice of a Novel Motor Skill

description: Although many studies have investigated mental workload during performance, its examination through functional connectivity during motor practice/learning is limited thus requiring further investigations. Therefore, this work aims to examine performance and functional connectivity dynamics underlying mental workload during motor practice by combining a robust computational method to derive connectivity and a human-machine interface which mitigates the use of participants’ prior motor experience since it can bias the acquisition process. Participants practiced reaching with a robotic arm through a head-controlled interface while kinematics and EEG were collected. The robotic end-effector kinematics quantified the performance and the Weighted Phase Lag Index indexed the connectivity during movement planning. Although performance improved during practice, the functional connectivity dynamics suggest that the recruitment of cognitive- motor resources decreased to a certain extent but that further training is likely needed to attenuate the mental workload. The work can also inform the training and design of assistive devices.
Permutation operators, entanglement entropy, and the XXZ spin chain in the limit Δ-> -1

description: In this paper we develop a new approach to the investigation of the bi-partite entanglement entropy in integrable quantum spin chains. Our method employs the well-known replica trick, thus taking a replica version of the spin chain model as starting point. At each site i of this new model we construct an operator T_i which acts as a cyclic permutation among the n replicas of the model. Infinite products of T_i give rise to local operators, precursors of branch-point twist fields of quantum field theory. The entanglement entropy is then expressed in terms of correlation functions of such operators. Employing this approach we investigate the von Neumann and Rényi entropies of a particularly interesting quantum state occurring as a limit (in a compact convergence topology) of the antiferromagnetic XXZ quantum spin chain. We find that, for large sizes, the entropy scales logarithmically, but not conformally.

description: We study the convective instability of the melt during the initial transient in a directional solidification experiment in a vertical configuration. We obtain analytically the dispersion relation, and perform an additional asymptotic expansion for large Rayleigh number that permits a simpler analytical analysis and a better numerical behavior. We find a transient instability, i.e. a regime in which the system destabilizes during the transient whereas the final unperturbed steady state is stable. This could be relevant to growth mode predictions in solidification.

Stability of nonlinear Vlasov-Poisson equilibria through spectral deformation and Fourier-Hermite expansion

Subjects: subject: Plasma Physics (physics.plasm-ph)

description: We study the stability of spatially periodic, nonlinear Vlasov-Poisson equilibria as an eigenproblem in a Fourier-Hermite basis (in the space and velocity variables, respectively) of finite dimension, $N$. When the advection term in Vlasov equation is dominant, the convergence with $N$ of the eigenvalues is rather slow, limiting the applicability of the method. We use the method of spectral deformation introduced in [J. D. Crawford and P. D. Hislop, Ann. Phys. 189, 265 (1989)] to selectively damp the continuum of neutral modes associated with the advection term, thus accelerating convergence. We validate and benchmark the performance of our method by reproducing the kinetic dispersion relation results for linear (spatially homogeneous) equilibria. Finally, we study the stability of a periodic Bernstein-Greene-Kruskal mode with multiple phase space vortices, compare our results with numerical simulations of the Vlasov-Poisson system and show that the initial unstable equilibrium may evolve to different asymptotic states depending on the way it was perturbed.

description: We reinterpret the generic CDF charged massive particle limit to obtain a limit on the mass of a stable or long-lived gluino. Various sources of uncertainty are examined. The $R$-hadron spectrum and scattering cross sections are modeled based on known low-energy hadron physics and the resultant uncertainties are quantified and found to be small compared to uncertainties from the scale dependence of the NLO pQCD production cross sections. The largest uncertainty in the limit comes from the unknown squark mass: when the squark -- gluino mass splitting is small, we obtain a gluino mass limit of 407 GeV, while in the limit of heavy squarks the gluino mass limit is 397 GeV. For arbitrary (degenerate) squark masses, we obtain a lower limit of 322 GeV on the gluino mass. These limits apply for any gluino lifetime longer than $\sim 30$ ns, and are the most stringent limits for such a long-lived or stable gluino.

description: This article outlines evidence-based methods for cultural heritage institutions to look for news and mentions about their collections and services online. Google Alerts were created for repository names, websites, and finding aid websites for 66 institutions randomly selected from the ArchiveGrid database. Results were analyzed to determine Google Alerts’ accuracy, what types of institutions would benefit most from using Google Alerts, what the content of the sources found by the alerts was, what types of publications returned the most results, and if Google Alerts could also identify image reuse. While Google Alerts’ accuracy for returning usable results for analysis was not very high, the structure of alert emails makes discarding irrelevant results simple and quick. Mid- to large-sized museums and institutions staging frequent exhibits and events, as well as those with active collections, return the largest number of alerts. News publications and social media publish the most content related to cultural heritage institutions. Though the sample set was small, Google Alerts also was able to identify image reuse.

description: The Saga: This note selectively unpacks the rapid evolution of the (Western) debate around the opportunity to deploy contact tracing apps, alongside other digital tools such as apps for symptoms sharing and immunity certificates to mitigate the Covid-19 pandemics. I do so from the perspective of a social scientist interested in the implications of the development of digital tools at times of emergency in terms of data governance. I argue that a more articulated reflection is needed towards the development of a healthy institutional structure that regulates the role of large tech platforms, such as Google and Apple (G&A), and public institutions, in governing data, particularly when health data and public value are involved. I unravel the saga of contact tracing apps in the UK and EU, looking at the technical, legal and ethical aspects and I attempt to draw more general lessons for data governance.
Discovery reach for generic supersymmetry at the LHC: MT2 versus missing transverse momentum selections for pMSSM searches

description: Different search strategies for supersymmetry have been employed by the LHC general-purpose experiments using early data. As proven by their early results, these strategies are promising, but raise the question of how well they will generalize for the future. We address this question by studying two thousand phenomenological minimal supersymmetric standard model parameter space points that come from a fit to indirect and cosmological data. We examine the 5 sigma discoverability of the points employing a typical ATLAS-type search based on missing transverse momentum (MET), a search based on an optimised MT2 cut and a combination of the two, taking into account standard model backgrounds. The discovery reach of the strategies can depend strongly on the systematic uncertainty in the background, subject to the stringency of the cuts and the details of the background simulation. By combining the MET and MT2 based strategies, with an integrated luminosity of 1 fb^-1 (10 fb^-1) at 7 TeV, 4-8% (42%) of the points are discoverable, depending on the systematic uncertainty on the background. At 14 TeV and with 10 fb^-1, 96% of the points are discoverable. While the majority of points can be discovered by both strategies at sqrt{s} = 14 TeV and with 1 fb^-1, there are some that are left undiscovered by a MET search strategy, but which are discovered by the MT2 strategy, and vice versa, therefore it is essential that one performs both in parallel. We discuss some of the factors that can make points more difficult to observe.

O(N) HIGH QUALITY REMESHING OF SURFACE MESHES

Year: 2021
Subjects: subject: Computer science
subject: Graphics
subject: Remeshing
subject: Surface Mesh

description: Generating high quality surface meshes is necessary as a prerequisite for many differentnumerical tasks. Given an input point cloud of a surface, several implementations exist in software and literature for initial triangulations on the surface. Problems arise, however, when these surface meshes are not of sufficient quality, often leading to problems with stability and floating point errors for numerical methods. Concretely, we observe that this is often the case for Boundary Element Methods. In this thesis, I propose and implement an algorithm for the remeshing of closed, genus 0 surface meshes using parameterization based on the discrete Laplace Beltrami operator. I generate boundary conditions using a cut by adding new points on the surface mesh according to the gradient of one of the parameters, and then generating the following parameter accordingly. After applying appropriate non-linear functions on the parameters such that they become analogous to spherical coordinates on a unit sphere, we can obtain an interpolated point cloud which approximates the underlying surface. The resulting point cloud can then be triangulated to obtain a mesh of higher quality. I describe and detail the use and development of a parallel sparse matrix solver, which mitigates one of the bottle necks of the algorithm, and then conclude by 1) detailing mesh quality improvement on several example meshes to demonstrate the effectiveness of the algorithm, and 2) detailing efficiency of the algorithm and describing future directions.

description: Pandemi Covid-19 yang melanda dunia, berdampak pada berhentinya berbagai sektor ekonomi. Pariwisata menjadi salah satu sektor yang paling terdampak pandemi. Pembatasan mobilitas orang langsung berdampak pada penurunan tajam bahkan berhentinya bisnis industri pariwisata (baik facility maupun activity). Situasi yang sama sekali tidak diduga oleh pelaku industri pariwisata, mengingat bencana ini datang ketika sektor pariwisata sedang berkembang pesat, bahkan pemerintah memprioritaskan sektor ini dalam pembangunan. Akibatnya terjadi pengangguran puluhan ribu pekerja pariwisata dan bisnis terkait di Jawa Tengah (pekerja ODTW, akomodasi wisata, transportasi wisata, bisnis oleh-oleh, dan sebagainya). Yang menjadi pertanyaan selanjutnya adalah bagaimana sektor pariwisata dapat bertahan di saat pandemi, baik menghadapi situasi saat ini maupun menyiapkan kembali untuk bangkit di masa mendatang? Tantangan bagi kita semua, dalam perpektif perencanaan pembangunan wilayah adalah menyiapkan sektor pariwisata yang mempunyai ketahanan yang kuat terhadap krisis.
Interpretation of fluorescence microscopy experiments on cell surface receptor dynamics with stochastic and deterministic mathematical models

description: Fluorescence microscopy has provided cellular biologists with quantifiable data, that can be paired with mathematical models to discover the mechanics of the imaged processes. We developed mathematical models to analyze data from two fluorescence techniques: direct Stochastic Optical Reconstruction Microscopy (dSTORM) and fluorescence recovery after photobleaching (FRAP). dSTORM is a super-resolution technique that uses photo-switchable fluorophores to achieve nanometer resolution images, allowing us to visualize the organization of proteins at nano-scales. However, dSTORM images can suffer from recording a single photo-switchable fluorophore multiple times, possibly creating artificial features. This is specially relevant in the analysis of membrane B-cell receptors clustering, where spatial clustering might relate to immune activation. I developed a protocol to estimate the number of unique fluorophores present in the experiment by coupling their temporal (with a Markov-chain model) and spatial (with a Gaussian mixture model) dynamics within a maximum likelihood framework. Previous studies have used the temporal information, but they have not coupled it with the spatial information (both localization and localization estimation error). I tested my protocol on simulated data, well-characterized DNA origami data and B-cell receptor data with positive results. My model is general enough to apply to other biological systems besides B-cell data and will enhance a microscopy technique that is widely used in biological applications. FRAP can be used to quantify the mobility of membrane proteins. We used it on live Drosophila organisms to study the outside-in pathway in cell adhesion to the extracellular matrix (ECM). We developed an ODE model to describe the recycling of the membrane protein, integrin, in charge of the adhesions. We found that both integrin and ECM ligands stabilize outside-in signalling and that relevant chemical treatments do not balance mutant integrin activation but stabilize the adhesions in control organisms. We also analyzed inside-out activation with a similar ODE model and by labeling the cytosolic protein talin. We found that talin is sensitive to increases and decreases in applied force. Disruptions of the intracellular force negatively affected adhesion stability. Increasing the force resulted in a faster assembly of new adhesions, whereas decreased forces increased the talin turnover.

description: The Vicsek model for the self-propelled particles is investigated with the respect to the introduction of the stochastic perturbation of the dynamics. It is shown that such a dependence can be thought in terms of the isomorphism of the Vicsek model with the Kuramoto model of spontaneous synchronization. They are isomorphic at least within the mean-field approach. The isomorphism between two models allows to state the dependence of the type of the transition in Vicsek model on the noise perturbation. Two types of noise the scalar and the vector ones lead to qualitatively different behavior with continuous and the discontinuous transition to ordered state correspondingly. New type of the stochastic perturbation - ``mixed`` noise is proposed. It is the weighted superposition of the scalar and vector noises. The corresponding phase diagram ``noise amplitude vs. interaction strength`` is obtained and the tricritical behavior for Vicsek model is demonstrated.

description: One important way to characterize the states having a gauge symmetry spontaneously broken over multibands should be to look at their collective excitation modes. We find that a three-band system has multiple Leggett modes with significantly different masses, which can be classified into different dynamical classes according to whether multiple inter-band Josephson currents add or cancel. This provides a way to dynamically characterize multiband superconductivity while the pairing symmetry is a static property.

description: Sterile neutrinos with a mass around the keV scale are an attractive particle physics candidate for Warm Dark Matter. Although many frameworks have been presented in which these neutrinos can fulfill all phenomenological constraints, there are hardly any models known that can explain such a peculiar mass pattern, one sterile neutrino at the keV scale and the other two considerably heavier, while at the same time being compatible with low-energy neutrino data. In this paper, we present models based on the Froggatt-Nielsen mechanism, which can give such an explanation. We explain how to assign Froggatt-Nielsen charges in a successful way, and we give a detailed discussion of all conditions to be fulfilled. It turns out that the typical arbitrariness of the charge assignments is greatly reduced when trying to carefully account for all constraints. We furthermore present analytical calculations of a few simplified models, while quasi-perfect models are found numerically.

Parity detection and entanglement with a Mach-Zehnder interferometer

description: A parity meter projects the state of two qubits onto two subspaces with different parities, the states in each parity class being indistinguishable. It has application in quantum information for its entanglement properties. In our work we consider the electronic Mach-Zehnder interferometer (MZI) coupled capacitively to two double quantum dots (DQDs), one on each arm of the MZI. These charge qubits couple linearly to the charge in the arms of the MZI. A key advantage of an MZI is that the qubits are well separated in distance so that mutual interaction between them is avoided. Assuming equal coupling between both DQDs and the arms and the same bias for each DQD, this setup usually detects three different currents, one for the odd states and two for each even state. Controlling the magnetic flux of the MZI, we can operate the MZI as a parity meter: only two currents are measured at the output, one for each parity class. In this configuration, the MZI acts as an ideal detector, its Heisenberg efficiency being maximal. For a class of initial states, the initially unentangled DQDs become entangled through the parity measurement process with probability one.

Spin liquids in graphene

Publisher: name: arXiv

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

description: We reveal that local interactions in graphene allow novel spin liquids between the semi-metal and antiferromagnetic Mott insulating phases, identified with algebraic spin liquid and Z$_{2}$ spin liquid, respectively. We argue that the algebraic spin liquid can be regarded as the two dimensional realization of one dimensional spin dynamics, where antiferromagnetic correlations show exactly the same power-law dependence as valence bond correlations. Nature of the Z$_{2}$ spin liquid turns out to be $d + i d'$ singlet pairing, but time reversal symmetry is preserved, taking $d + i d'$ in one valley and $d - i d'$ in the other valley. We propose the quantized thermal valley Hall effect as an essential feature of this gapped spin liquid state. Quantum phase transitions among the semi-metal, algebraic spin liquid, and Z$_{2}$ spin liquid are shown to be continuous while the transition from the Z$_{2}$ spin liquid to the antiferromagnetic Mott insulator turns out to be the first order. We emphasize that both algebraic spin liquid and $d \pm id'$ Z$_{2}$ spin liquid can be verified by the quantum Monte Carlo simulation, showing the enhanced symmetry in the algebraic spin liquid and the quantized thermal valley Hall effect in the Z$_{2}$ spin liquid.
The effects of stumping and tree species composition on the soil microbial community in the interior cedar-hemlock zone, British Columbia
Creators: name: Modi, Dixi

description: Stump removal (stumping) is an effective forest management practice used to reduce the mortality of trees affected by fungal pathogen-mediated root diseases such as Armillaria root rot, but its impact on soil microbial community structure has not been ascertained. This study investigated the long-term impact of stumping and tree species composition on the abundance, diversity and taxonomic composition of soil fungal and bacterial communities in a 48-year-old trial at Skimikin, British Columbia. We used DNA metabarcoding targeting the fungal internal transcribed spacer (ITS) marker and the bacterial 16S rRNA gene to decipher the microbiomes. A total of 108 samples were collected from the FH (fermented and humus layers), 0-10 cm (A horizon) and 10-20 cm (B horizon) layers in 36 plots, 18 stumped and 18 unstumped, that were planted with pure stands and admixtures of Douglas-fir, western redcedar and paper birch. Fungal α-diversity in the A horizon increased with stumping regardless of tree species composition and had a tendency to increase in the FH and B horizons. In the FH horizon, the relative abundance of the saprotrophic fungal community declined while that of ectomycorrhizal (ECM) fungal community increased with stumping. Bacterial α-diversity in the B horizon declined with stumping, irrespective of tree species, and also tended to decrease in the A horizon. The B horizon of stumped plots was significantly enriched with potential plant growth-promoting bacteria (PGPR), such as rhizobia. Similarly, Pseudomonadales, known for their antagonistic role against pathogens, increased significantly in all three soil horizons with stumping and was especially observed in association with birch and its admixtures. The culture-based assessment focused on 16S rDNA substantiated the dominance of potential PGPRs in the stumped plots. Furthermore, molecular characterization of Armillaria using translation elongation factor-1 alpha (tef-1) and ITS revealed the occurrence of A. gallica, reported for the first time at this site. Overall, we conclude that stumping along with plantation of resistant tree species with susceptible ones, led to a healthy fungal community structure and promotion of a beneficial bacterial microbiome, thus proves as a potent practice for the suppression of Armillaria root rot and promotion of forest health.
