description: A model of correlated particles described by a generalized probability theory is suggested whose dynamics is subject to a non-linear version of Schrödinger equation. Such equations arise in many different contexts, most notably in the proposals for the gravitationally induced collapse of wave function. Here, it is shown that the consequence of the connection demonstrates a possible deviation of the theory from the standard formulation of quantum mechanics in the probability prediction of experiments. The links are identified from the fact that the analytic solution of the equation is given by Dirichlet eigenvalues which can be expressed by generalized trigonometric function. Consequently, modified formulation of Born's rule is obtained by relating the event probability of the measuement to an arbitrary exponent of the modulus of the eigenvalue solution. Such system, which is subject to the non-linear dynamic equation, illustrates the violation of the Clauser-Hore-Shimony-Holt inequality proportional to the degree of the non-linearity as it can be tested by a real experiment. Depending upon the degree, it is found that the violation can go beyond Tsirelson bound $2\sqrt{2}$ and reaches to the value of nonlocal box.

description: The ITER electron cyclotron upper launcher (EC UL) is used to direct high power microwave beams generated by the gyrotrons into the plasma for magneto-hydrodynamic (MHD) control and heating and current drive (H&CD) applications. The UL consists of an assembly of ex-vessel waveguides (WGs) and an in-vessel port plug. The diamond window units form vacuum and tritium confinement boundaries between the torus volume and the transmission lines (TLs) which guide beams between 1 and 2 MW from the gyrotrons to the launcher.

description: Soil aquifer treatment (SAT), applied after activated sludge treatment (AST), has been widely used for wastewater reclamation. AST and SAT show potential for removing micropollutants, including pharmaceuticals and personal care products (PPCPs). However, the role of sequential combination of AST and SAT on the biodegradation of PPCPs was not clear in previous studies. In this study, the removal characteristics of PPCPs in AST and SAT were evaluated to assess the legitimacy of sequential combination of AST and SAT. SAT showed effective removals of antibiotics (> 80%), including fluoroquinolones and macrolides by sorption, but poor removals of amide pharmaceuticals (i.e. carbamazepine and crotamiton) were observed in both AST and SAT. Additionally, biodegradation contributed to the effective removal of carboxylic PPCPs (i.e. ketoprofen and gemfibrozil) in both ASTs and SAT, but effective biodegradation of halogenated acid and polycyclic aromatic compounds (i.e. clofibric acid and naproxen) was observed only in SAT (82.1% and 81.8%, respectively). Furthermore, the microbial substrate metabolic patterns showed that amino acids, amines, and polymers were biodegradable in SAT, which was fit for the biodegradation characteristics of PPCPs in SAT. For microbial communities, Proteobacteria were dominant in AST and SAT, but Acidobacteria and Actinobacteria were more abundant in SAT than AST, which could contribute to the effective removals of halogenated acid in SAT. Considering PPCP biodegradation and substrate metabolism, SAT displays a wider range on the biodegradation than AST. Therefore, we conclude that these two processes can complement each other when used for controlling PPCPs.

description: Quantum measurements can be interpreted as a generalisation of probability vectors, in which non-negative real numbers are replaced by positive semi-definite operators. We extrapolate this analogy to define a generalisation of doubly stochastic matrices that we call doubly normalised tensors (DNTs), and formulate a corresponding version of Birkhoff-von Neumann's theorem, which states that permutations are the extremal points of the set of doubly stochastic matrices. We prove that joint measurability arises as a mathematical feature of DNTs in this context, needed to establish a characterisation similar to Birkhoff-von Neumann's. Conversely, we also show that DNTs emerge naturally from a particular instance of a joint measurability problem, remarking its relevance in general operator theory.

description: Every compact aspherical Riemannian manifold admits a canonical series of orbibundle structures with infrasolv fibers which is called its infrasolv tower. The tower arises from the solvable radicals of isometry group actions on the universal covers. Its length and the geometry of its base measure the degree of continuous symmetry of an aspherical Riemannian manifold. We say that the manifold has large symmetry if it admits an infrasolv tower whose base is a locally homogeneous space. We construct examples of aspherical manifolds with large symmetry, which do not support any locally homogeneous Riemannian metrics.

description: A sublimation process governs the innermost region of the dusty torus of active galactic nuclei. However, the observed inner radius of the torus is systematically smaller than the expected radius by a factor of ~ 1/3. We show that the anisotropy of the emission from accretion disks resolves this conflict naturally and quantitatively. An accretion disk emits lesser radiation in the direction closer to its equatorial plane (i.e., to the torus). We find that the anisotropy makes the torus inner region closer to the central black hole and concave. Moreover, the innermost edge of the torus may connect with the outermost edge of the disk continuously. Considering the anisotropic emission of each clump in the torus, we calculate the near-infrared flux variation in response to a UV flash. For an observer at the polar angle theta_obs = 25 deg, the centroid of the time delay is found to be 37% of the delay expected in the case of isotropic illumination, which explains the observed systematic deviation.

Adherence in e-health interventions for substance use and the factors influencing it : systematic review, meta-analysis, and meta-regression
Creators: name: Shams, Farhud
Publisher: name: University of British Columbia
Year: 2022

description: Background: Globally, around 36 million people have a drug use disorder, while only one in eight receive the treatment they need. Research and development of e-health interventions targeting substance use have been becoming increasingly popular in the last decade, due to their unique ability to reach wide populations. Low exposure of participants and adherence to interventions and their content has been a widely dis-cussed issue in the literature of e-health interventions. Adherence in e-health interven-tions is defined as “the degree to which individuals experience the content of the Inter-net intervention”. Although adherence may be an important factor in determining the effectiveness of an intervention targeting substance use, not many studies have been specifically focusing on this aspect. Objectives: In this review, we set out to analyze the data on adherence from studies on e-health interventions targeting substance use and assess four predictors of ad-herence. The four factors that were hypothesized to predict adherence were guidance, blended treatment, recruitment, and treatment duration. Methods: A systematic review of published literature from 2009-2020 was conducted and data on two adherence measures and predictors of adherence were extracted. The two adherence measures were (1) the mean proportion of modules completed across the intervention group and (2) the proportion of participants that completed all modules. Results: The overall pooled adherence rate was 0.60 (95%-CI: 0.52-0.67) for the mean proportion of modules completed across 30 intervention arms and 0.47 (95%-CI: 0.35-0.59) for the proportion of participants that completed all modules across nine in-tervention arms. Four meta-regression models assessed each covariate. The three variables guidance, blended treatment, and recruitment were statistically significant predictors of adherence. Treatment duration was not a significant predictor of adher-ence. Conclusion: The results of the present review suggest that there may be some predic-tors of adherence that should be considered in further investigations and develop-ments of interventions. Future studies should put a greater emphasis on reporting ad-herence, as that would allow for more accurate meta-analyses and predictor models to help improve understanding of adherence and its predictors.

description: This article presents a statistical analysis of the vulnerabilities of modern software. The vulnerabilities were analyzed by error types and CVSS severity. The actual task of the security service of any organization is to protect against external and internal threats. During attacks, cybercriminals use means and methods to penetrate the infrastructure, anchor in it and hide the traces of attacks. Stages of attacks are carried out through the exploitation of both those already found by information security specialists, but not fixed in the attacked infrastructure, and using undetected vulnerabilities called "zero-day vulnerabilities." Statistical analysis of vulnerabilities will help information security specialists and software developers understand which testing and which errors need to spend more time. To reduce the amount of manual work, it is common practice for specialists to use automatic scanning tools. But vulnerability scanners have costs (false positives and false negatives), so the data obtained during the scan must be rechecked manually.

description: We study the $L^{2}$-boundedness of the $3$-dimensional (Heisenberg) Riesz transform on intrinsic Lipschitz graphs in the first Heisenberg group $\mathbb{H}$. Inspired by the notion of vertical perimeter, recently defined and studied by Lafforgue, Naor, and Young, we first introduce new scale and translation invariant coefficients $\operatorname{osc}_Ω(B(q,r))$. These coefficients quantify the vertical oscillation of a domain $Ω\subset \mathbb{H}$ around a point $q \in \partial Ω$, at scale $r > 0$. We then proceed to show that if $Ω$ is a domain bounded by an intrinsic Lipschitz graph $Γ$, and $$\int_{0}^{\infty} \operatorname{osc}_Ω(B(q,r)) \, \frac{dr}{r} \leq C < \infty, \qquad q \in Γ,$$ then the Riesz transform is $L^{2}$-bounded on $Γ$. As an application, we deduce the boundedness of the Riesz transform whenever the intrinsic Lipschitz parametrisation of $Γ$ is an $ε$ better than $\tfrac{1}{2}$-Hölder continuous in the vertical direction. We also study the connections between the vertical oscillation coefficients, the vertical perimeter, and the natural Heisenberg analogues of the $β$-numbers of Jones, David, and Semmes. Notably, we show that the $L^{p}$-vertical perimeter of an intrinsic Lipschitz domain $Ω$ is controlled from above by the $p^{th}$ powers of the $L^{1}$-based $β$-numbers of $\partial Ω$.

description: We present a large sample which contains 45 Seyfert 1 galaxies (Sy1s), 46 hidden broad-line region (HBLR) Seyfert 2 galaxies (Sy2s), 57 non-HBLR Sy2s, and 22 starburst galaxies to distinguish their properties and to seek the possible evolution of active galactic nuclei (AGNs) and starburst galaxies. We show that (1) using a plot of [O III] ł5007/H/alpha versus [N II] ł6584/H/alpha of standard optical spectral diagnostic diagrams, we find that a equation can separate well non-HBLR Sy2s and HBLR Sy2s; (2) the emission-line ratios and both the combination of the ratios and polycyclic aromatic hydrocarbon (PAH) strength are utilized effectively to separate starburst galaxies and Seyfert galaxies; (3) we compare a number of quantities from the data and confirm well the separations with statistics; (4) on the basis of statistics, we suggest that HBLR Sy2s may be the counterparts of Sy1s at edge-on orientation. In addition, we discuss the possibility of starburst galaxies evolving to non-HBLR Sy2s and HBLR Sy2s and then evolving to Sy1s based on the statistical analysis.

description: Let $q = e^{i θ} \in \mathbb{T}$ (where $θ\in \mathbb{R}$), and let $u,v$ be $q$-commuting unitaries, i.e., $u$ and $v$ are unitaries such that $vu = quv$. In this paper we find the optimal constant $c = c_θ$ such that $u,v$ can be dilated to a pair of operators $c U, c V$, where $U$ and $V$ are commuting unitaries. We show that \[ c_θ= \frac{4}{\|u_θ+u_θ^*+v_θ+v_θ^*\|}, \] where $u_θ, v_θ$ are the universal $q$-commuting pair of unitaries, and we give numerical estimates for the above quantity. In the course of our proof, we also consider dilating $q$-commuting unitaries to scalar multiples of $q'$-commuting unitaries. The techniques that we develop allow us to give new and simple "dilation theoretic" proofs of well known results regarding the continuity of the field of rotations algebras. In particular, for the so-called "Almost Mathieu Operator" $h_θ= u_θ+u_θ^*+v_θ+v_θ^*$, we recover the fact that the norm $\|h_θ\|$ is a Lipshitz continuous function of $θ$, as well as the result that the spectrum $σ(h_θ)$ is a $\frac{1}{2}$-Hölder continuous function in $θ$ with respect to the Hausdorff metric. In fact, we obtain this Hölder continuity of the spectrum for every selfadjoint $*$-polynomial $p(u_θ,v_θ)$, which in turn endows the rotation algebras with the natural structure of a continuous field of C*-algebras.

description: The LASSO is an attractive regularisation method for linear regression that combines variable selection with an efficient computation procedure. This paper is concerned with enhancing the performance of LASSO for square-free hierarchical polynomial models when combining validation error with a measure of model complexity. The measure of the complexity is the sum of Betti numbers of the model which is seen as a simplicial complex, and we describe the model in terms of components and cycles, borrowing from recent developments in computational topology. We study and propose an algorithm which combines statistical and topological criteria. This compound criterion would allow us to deal with model selection problems in polynomial regression models containing higher-order interactions. Simulation results demonstrate that the compound criteria produce sparser models with lower prediction errors than the estimators of several other statistical methods for higher order interaction models.

description: Estimating the volume of a convex body is a central problem in convex geometry and can be viewed as a continuous version of counting. We present a quantum algorithm that estimates the volume of an $n$-dimensional convex body within multiplicative error $ε$ using $\tilde{O}(n^{3}+n^{2.5}/ε)$ queries to a membership oracle and $\tilde{O}(n^{5}+n^{4.5}/ε)$ additional arithmetic operations. For comparison, the best known classical algorithm uses $\tilde{O}(n^{4}+n^{3}/ε^{2})$ queries and $\tilde{O}(n^{6}+n^{5}/ε^{2})$ additional arithmetic operations. To the best of our knowledge, this is the first quantum speedup for volume estimation. Our algorithm is based on a refined framework for speeding up simulated annealing algorithms that might be of independent interest. This framework applies in the setting of "Chebyshev cooling", where the solution is expressed as a telescoping product of ratios, each having bounded variance. We develop several novel techniques when implementing our framework, including a theory of continuous-space quantum walks with rigorous bounds on discretization error. To complement our quantum algorithms, we also prove that volume estimation requires $Ω(\sqrt n+1/ε)$ quantum membership queries, which rules out the possibility of exponential quantum speedup in $n$ and shows optimality of our algorithm in $1/ε$ up to poly-logarithmic factors.

description: We examine the density profiles of the quantum degenerate Bose-Fermi mixture of $^{174}$Yb-$^{173}$Yb, experimental observed recently, in the mean field regime. In this mixture there is a possibility of tuning the Bose-Bose and Bose-Fermi interactions simultaneously using two well separated optical Feshbach resonances, and it is a good candidate to explore phase separation in Bose-Fermi mixtures. Depending on the Bose-Bose scattering length $a_\BB$, as the Bose-Fermi interaction is tuned the density of the fermions is pinched or swapping with bosons occurs.

We show that these varieties are symplectic singularities and classify which admit symplectic resolutions. The classification reduces to the semi-simple case, where we show that a resolution exists if and only if either $g=1$ and $G$ is a product of special linear groups of any rank and copies of the group $PGL_2$, or if $g=2$ and $G = (SL_2)^m$ for some $m$.

Convolutions of Totally Positive Distributions with applications to Kernel Density Estimation

Year: 2019

description: In this work we study the estimation of the density of a totally positive random vector. Total positivity of the distribution of a random vector implies a strong form of positive dependence between its coordinates and, in particular, it implies positive association. Since estimating a totally positive density is a non-parametric problem, we take on a (modified) kernel density estimation approach. Our main result is that the sum of scaled standard Gaussian bumps centered at a min-max closed set provably yields a totally positive distribution. Hence, our strategy for producing a totally positive estimator is to form the min-max closure of the set of samples, and output a sum of Gaussian bumps centered at the points in this set. We can frame this sum as a convolution between the uniform distribution on a min-max closed set and a scaled standard Gaussian. We further conjecture that convolving any totally positive density with a standard Gaussian remains totally positive.
The cultural politics of a just transition in the Canadian Oil Sands
Creators: name: Muzzerall, Parker
Publisher: name: University of British Columbia
Year: 2022

description: In order to prevent the most severe impacts of climate change, we must transition to a low-carbon energy system. However, the process of decarbonization faces significant cultural and political barriers, especially within fossil fuel producing regions where the impacts of decarbonization policy are felt most directly. To overcome these barriers, both scholars and policy makers have begun to call for a just transition for affected communities in an effort to centre justice and equity concerns in the process of decarbonization. While the limited attempts at implementing a just transition program have largely been confined to the coal sector, the Canadian Federal Government has started to develop a more expansive just transition framework for the entire fossil fuel sector. Little is known, though, about how those living and working in the Canadian Oil Sands, home to 97% of Canadian fossil fuel reserves, feel about this proposal. To address this gap, I orient this study around the question: how do those living and working in the Canadian Oil Sands interpret the proposal for a just transition? Using data collected through 18 semi-structured interviews with industry and community members in the Oil Sands town of Fort McMurray, I show how the cultural and political conditions endemic to fossil fuel producing regions are largely incommensurate with a just transition program as it is currently conceptualized in the scholarly literature and materialized through government policy. Drawing on my participants’ perspectives on climate change, low-carbon energy alternatives, regional politics, and the proposal for a just transition specifically, I offer evidence for this conclusion while also advocating for the continued development of just transition programs, albeit ones that center the localized cultural conditions and concerns of the communities for which they are intended to serve.

description: Exact analytic solutions for a class of scalar-tensor gravity theories with a hyperbolic scalar potential are presented. Using an exact solution we have successfully constructed a model of inflation that produces the spectral index, the running of the spectral index and the amplitude of scalar perturbations within the constraints given by the WMAP 7 years data. The model simultaneously describes the Big Bang and inflation connected by a specific time delay between them so that these two events are regarded as dependent on each other. In solving the Fridemann equations, we have utilized an essential Weyl symmetry of our theory in 3+1 dimensions which is a predicted remaining symmetry of 2T-physics field theory in 4+2 dimensions. This led to a new method of obtaining analytic solutions in 1T field theory which could in principle be used to solve more complicated theories with more scalar fields. Some additional distinguishing properties of the solution includes the fact that there are early periods of time when the slow roll approximation is not valid. Furthermore, the inflaton does not decrease monotonically with time, rather it oscillates around the potential minimum while settling down, unlike the slow roll approximation. While the model we used for illustration purposes is realistic in most respects, it lacks a mechanism for stopping inflation. The technique of obtaining analytic solutions opens a new window for studying inflation, and other applications, more precisely than using approximations.

description: SONYC - Substellar Objects in Nearby Young Clusters - is a survey program to investigate the frequency and properties of brown dwarfs down to masses below the Deuterium burning limit in nearby star forming regions. In this second paper, we present results on the ~1 Myr old cluster Rho Ophiuchi, combining our own deep optical and near-infrared imaging using Subaru with photometry from the 2-Micron All Sky Survey and the Spitzer Space Telescope. Of the candidates selected from iJKs photometry, we have confirmed three -- including a new brown dwarf with a mass close to the Deuterium limit -- as likely cluster members through low-resolution infrared spectroscopy. We also identify 27 sub-stellar candidates with mid-infrared excess consistent with disk emission, of which 16 are new and 11 are previously spectroscopically confirmed brown dwarfs. The high and variable extinction makes it difficult to obtain the complete sub-stellar population in this region. However, current data suggest that its ratio of low-mass stars to brown dwarfs in similar to those reported for several other clusters, though higher than what was found for NGC 1333 in Scholz et al. 2009.

description: Consider a bunch of interacting electrons confined in a quantum dot. The later is suddenly coupled to semi-infinite biased leads at an initial instant $t=0$. We identify the dominant contribution to the ergodic current in the off-resonant transport regime, in which the discrete spectrum of the quantum dot is well separated from the absolutely continuous spectrum of the leads. Our approach allows for arbitrary strength of the electron-electron interaction while the current is expanded in even powers of the (weak) lead-dot hopping constant $τ$. We provide explicit calculations for sequential tunneling and cotunneling contributions to the current. In the interacting case it turns out that the cotunneling current depends on the initial many-body configuration of the sample, while in the non-interacting case it does not, and coincides with the first term in the expansion of the Landauer formula w.r.t $τ$.

description: We predict and analyze {\it radiation-induced quantum interference effect} in low-dimensional $n$-$p$ junctions. This phenomenon manifests itself by large oscillations of the photocurrent as a function of the gate voltage or the frequency of the radiation. The oscillations result from the quantum interference between two electron paths accompanied by resonant absorption of photons. They resemble Ramsey quantum beating and Stueckelberg oscillations well-known in atomic physics. The effect can be observed in one- and two-dimensional $n$-$p$ junctions based on nanowires, carbon nanotubes, monolayer or bilayer graphene nanoribbons.

description: This work is devoted to the development of a sensing element of a three-axis capacitive microelectromechanical accelerometer. The relevance of the work is due to the rapidly developing market of miniature sensors, in particular devices designed for the "Internet of things", IoT. The development was carried out based on the technological capabilities of Russian manufacture.In the course of the work, mathematical modeling and modeling by the finite element method were carried out. In the proposed design, acceleration measurements are performed on all three axes simultaneously using a system of moving mass, elastic suspension and an electrode structure of the "gap-closing" type. The result was the structure of the sensing element satisfying the stated technical requirements.
Some Applications of Group Theoretic Rips Constructions to the Classification of von Neumann Algebras

description: In this paper we study various von Neumann algebraic rigidity aspects for the property (T) groups that arise via the Rips construction developed by Belegradek and Osin in geometric group theory \cite{BO06}. Specifically, developing a new interplay between Popa's deformation/rigidity theory \cite{Po07} and geometric group theory methods we show that several algebraic features of these groups are completely recognizable from the von Neumann algebraic structure. In particular, we obtain new infinite families of pairwise non-isomorphic property (T) group factors thereby providing positive evidence towards Connes' Rigidity Conjecture. In addition, we use the Rips construction to build examples of property (T) II$_1$ factors which posses maximal von Neumann subalgebras without property (T) which answers a question raised in an earlier version of \cite{JS19} by Y. Jiang and A. Skalski.

description: We review recent developments in the QCD description of jet production and modification in reactions with heavy nuclei at relativistic energies. Our goal is to formulate a perturbative expansion in the presence of nuclear matter that allows to systematically improve the accuracy of the theoretical predictions. As an example, we present calculations of inclusive jet cross sections at RHIC, Z0/gamma*-tagged jet cross sections at the LHC, and jet shapes that include both next-to-leading order perturbative effects and the effects of the nuclear medium.

description: We use weighted $L^2$-methods to obtain sharp pointwise estimates for the canonical solution to the equation $\bar\partial u=f$ on smoothly bounded strictly convex domains and the Cartan classical domain domains when $f$ is bounded in the Bergman metric $g$. We provide examples to show our pointwise estimates are sharp. In particular, we show that on the Cartan classical domains $Ω$ of rank $2$ the maximum blow up order is greater than $-\log δ_Ω(z)$, which was obtained for the unit ball case by Berndtsson. For example, for IV$(n)$ with $n \geq 3$, the maximum blow up order is $δ(z)^{1 -{n \over 2}}$ because of the contribution of the Bergman kernel. Additionally, we obtain uniform estimates for the canonical solutions on the polydiscs, strictly pseudoconvex domains and the Cartan classical domains under stronger conditions on $f$.

Flows and heterogeneities with a vane tool: Magnetic resonance imaging measurements

description: We study the local flow properties of various materials in a vane-in-cup geometry. We use magnetic resonance imaging techniques to measure velocities and particle concentrations in flowing Newtonian fluid, yield stress fluid, and in a concentrated suspension of noncolloidal particles in a yield stress fluid. In the Newtonian fluid, we observe that the $θ$-averaged strain rate component $d_{r,θ}$ decreases as the inverse squared radius in the gap, in agreement with a Couette analogy. This allows direct comparison (without end-effect corrections) of the resistances to shear in vane and Couette geometries. Here, the mean shear stress in the vane-in-cup geometry is slightly lower than in a Couette cell of same dimensions, and a little higher than when the vane is embedded in an infinite medium. We also observe that the flow enters deeply the region between the blades, leading to significant extensional flow. In the yield stress fluid, in contrast with the usually accepted picture based on simulation results from the literature, we find that the layer of material that is sheared near the blades at low velocity is not cylindrical. There is thus a significant extensional component of shear that should be taken into account in the analysis. Finally and surprisingly, in the suspension, we observe that a thin non-cylindrical slip layer made of the pure interstitial yield stress fluid appears quickly at the interface between the sheared material and the material that moves as a rigid body between the blades. This feature can be attributed to the non-symmetric trajectories of the noncolloidal particles around the edges of the blades. This new important observation is in sharp contradiction with the common belief that the vane tool prevents slippage and may preclude the use of the vane tool for studying the flows of pasty materials with large particles.

description: Hejair, Fawaz, “Recommendations for the Reduction of Pots Inventory for the Hejair company”, Bachelor of Science in Industrial Engineering, May 2023, Dennis Gawlik.This case study explains the excess inventory issue within the Hejair company. The increase in inventory is hindering the progress of Hejair company. The methodology used to analyze the Hejair company’s problem of excess pot inventory included the DMAIC approach (Define, Measure, Analyze, Improve, and Control). This method is used to define the aspects of the problem and is utilized to find a solution. The Pugh matrix was also utilized to decide which recommended approach should be selected. This recommendation would allow for the clearing of the backlog of pots stock soon.A major issue with inventory management was on hardcopy and that storage for the pots inventory was running out. Their forecast was also flawed due to an unnatural phenomenon, the COVID-19 pandemic, hence this led to over-ordering of the products.Objectives and recommended potential outcomes were created for the Hejair company to consider implementing with the aim of reducing excess pot inventory to sale levels in 2024.
Metal-insulator transition on SrTiO$_{3}$ surface induced by ionic-bombardment

description: SrTiO$_{3}$ is one of the most popular insulating single-crystal substrates for various complex-oxide thin film growths, because of its good lattice match with many complex oxide films. Here, we show that a common thin film processing technique, argon ion-milling, creates highly conducting layer on the surface of STO, not only at room temperatures but also at cryogenic temperatures at which thermal diffusion is completely suppressed. Systematic \emph{in situ} four-point conductance measurements were taken on single-crystal STO substrates inside vacuum environment. The evolution of metallicity out of insulating STO follows simple models based on oxygen vacancy doping effect. At cryogenic temperatures, ion milling created a thin - but much thicker than the argon-penetration depth - steady-state oxygen-vacant layer, leading to a highly-concentric metallic state. Near room temperatures, however, significant thermal diffusion occurred and the metallic state continuously diffused into the bulk, leaving only low concentraion of electron carriers on the surface. Analysis of the discrepancy between the experiments and the models also provided evidence for vacany clustering, which seems to occur during any vacancy formation process and affects the observed conductance. These observations suggest that the transport properties of films processed on STO substrates using energetic methods such as ion milling need to be taken with caution. On the other hand, if properly controlled, ionic bombardment could be used as a way to create selective conducting layers on the surface of STO for device applications.

PROPERTIES OF THE GAIA-ICRF3 RADIO-OPTICAL REFERENCE FRAME

Publisher: name: Zenodo
Year: 2019

description: The radio-optical reference frame tie is based on a few thousand radio-loud quasars listed in the ICRF3 with sufficiently bright optical counterparts to be observed by Gaia. The positions of these sources do not always match within reasonably expected errors; with about 1/5 of the pre-selected sources showing large offsets. We collect a sample of some 2100 quasars; which are not perturbed and appear to be bona fide point-like sources.

With these vetted sources; we perform analysis of the reference frame differences using the vector spherical harmonic decomposition and singular value decomposition. The estimated parameters quantify possible systematic errors; as well as important physical phenomena such as the acceleration of the Solar barycenter. The eigenvalues indicate the weak spots of the current reference frame.
