description: We present investigations on single Ni/Si related color centers produced via ion implantation into single crystalline type IIa CVD diamond. Testing different ion dose combinations we show that there is an upper limit for both the Ni and the Si dose 10^12/cm^2 and 10^10/cm^2 resp.) due to creation of excess fluorescent background. We demonstrate creation of Ni/Si related centers showing emission in the spectral range between 767nm and 775nm and narrow line-widths of 2nm FWHM at room temperature. Measurements of the intensity auto-correlation functions prove single-photon emission. The investigated color centers can be coarsely divided into two groups: Drawing from photon statistics and the degree of polarization in excitation and emission we find that some color centers behave as two-level, single-dipole systems whereas other centers exhibit three levels and contributions from two orthogonal dipoles. In addition, some color centers feature stable and bright emission with saturation count rates up to 78kcounts/s whereas others show fluctuating count rates and three-level blinking.

description: We will show that almost all nonassociative relation algebras are symmetric and integral (in the sense that the fraction of both labelled and unlabelled structures that are symmetric and integral tends to 1), and using a Fraïssé limit, we will establish that the classes of all atom structures of nonassociative relation algebras and relation algebras both have 0-1 laws. As a consequence, we obtain improved asymptotic formulas for the numbers of these structures and broaden some known probabilistic results on relation algebras.

description: We explore the "Beautiful Mirrors" model, which aims to explain the measured value of $A^b_{FB}$, discrepant at the $2.9σ$ level. This scenario introduces vector-like quarks which mix with the bottom, subtly affecting its coupling to the $Z$. The spectrum of the new particles consists of two bottom-like quarks and a charge -4/3 quark, all of which have electroweak interactions with the third generation. We explore the phenomenology and discovery reach for these new particles at the LHC, exploring single mirror quark production modes whose rates are proportional to the same mixing parameters which resolve the $A_{FB}^b$ anomaly. We find that for mirror quark masses $\lesssim 500 GeV, a 14 TeV LHC with 300 {\rm fb}^{-1}$ is required to reasonably establish the scenario and extract the relevant mixing parameters.

Assessing physical habitat and juvenile salmonid populations in small coastal streams in summer using traditional sampling and advanced remote sensing approaches
Creators: name: Nonis, Alyssa D.
Publisher: name: University of British Columbia
Year: 2022

description: Freshwater habitat loss is a major threat to the persistence of salmonid (Oncorhynchus spp.) populations in the Pacific Northwest of North America. To better inform where and when to preserve this critical habitat, information on its extent and quality is required over spatial scales fish use for various life stages. Further, current and accurate habitat associations are required to make location-specific conservation recommendations. Given the limitations of fine-scale analysis due to sampling logistics and that land conversion activities and climate change affect stream salmonids on extremely large spatial scales, approaches to extend small-scale fish-habitat assessments accurately and cost-effectively to the watershed level are needed. To address this challenge, I investigated the habitat associations of juvenile rainbow trout (Oncorhynchus mykiss) and Dolly Varden char (Salvelinus malma) in the Nahmint watershed on Vancouver Island, British Columbia, during summer 2019. I also assessed whether 3-D Airborne laser scanning (ALS) derived measurements of small stream characteristics provided similar explanatory power in establishing habitat associations with physical characteristics as conventional field-based surveys. I surveyed 200 m of habitat across varying tributary stream sizes (5.1 m to 10.6 m) and implemented mark-recapture fish sampling using minnow traps and passive integrated transponder tags to establish habitat associations and characterize movement. The density of both species was significantly higher in pool habitats than in glides and riffles. Generally, restricted movement was observed by both species, with some Dolly Varden char moving in a primarily downstream direction. Further, ALS-measured and field-measured variables produced similar habitat associations, with fish presence and density associated with pool habitats classified by the ALS data. Overall, these results highlight the importance of habitat quality (such as abundant pools) and connectivity in small streams, while also illustrating the utility of using ALS -derived measures of small stream habitat to establish fine-scale habitat associations of juvenile salmonids within a watershed. Moreover, ALS has the potential to be used as a predictive tool to assess juvenile salmonid distributions at a broad scale in a timely and cost-effective way.
X-ray Emission from Optically Selected Radio-Intermediate and Radio-Loud Quasars

description: We present the results of an investigation into the X-ray properties of radio-intermediate and radio-loud quasars (RIQs and RLQs, respectively). We combine large, modern optical (e.g., SDSS) and radio (e.g., FIRST) surveys with archival X-ray data from Chandra, XMM-Newton, and ROSAT to generate an optically selected sample that includes 188 RIQs and 603 RLQs. This sample is constructed independently of X-ray properties but has a high X-ray detection rate (85%); it provides broad and dense coverage of the l-z plane, including at high redshifts (22% of objects have z=2-5), and it extends to high radio-loudness values (33% of objects have R*=3-5, using logarithmic units). We measure the "excess" X-ray luminosity of RIQs and RLQs relative to radio-quiet quasars (RQQs) as a function of radio loudness and luminosity, and parameterize the X-ray luminosity of RIQs and RLQs both as a function of optical/UV luminosity and also as a joint function of optical/UV and radio luminosity. RIQs are only modestly X-ray bright relative to RQQs; it is only at high values of radio-loudness (R*>3.5) and radio luminosity that RLQs become strongly X-ray bright. We find no evidence for evolution in the X-ray properties of RIQs and RLQs with redshift (implying jet-linked IC/CMB emission does not contribute substantially to the nuclear X-ray continuum). Finally, we consider a model in which the nuclear X-ray emission contains both disk/corona-linked and jet-linked components and demonstrate that the X-ray jet-linked emission is likely beamed but to a lesser degree than applies to the radio jet. This model is used to investigate the increasing dominance of jet-linked X-ray emission at low inclinations.

Impact of spectral noise shape and correlations of laser beam jitter on acquiring optical links in space

Subjects: subject: Instrumentation and Detectors (physics.ins-det)

description: We investigate how the probability of acquiring an optical link between a scanning and a target spacecraft depends on the spectral shape, power and dimensionality of the beam jitter, as well as on the choice of detector integration time, beam detection radius and scan speed. For slow scans and long integration times, the probability of failure (Pfail) is determined by the integrated jitter power up to a critical frequency, which we verify by comparing the results of an analytical model to those of Monte Carlo simulations. Jitter above the critical frequency leads to a loss of correlation between integration windows and decreases Pfail for both, 1d (radial) and 2d (radial and tangential) jitter, as long as the RMS jitter amplitude does not exceed the beam diameter. In the opposite limit of fast scans and short integration times, emergent correlations between jitter fluctuations on two adjacent scanning tracks also decrease Pfail. The analytical model is additionally used to assess the effect of multiple overlapping tracks and the impact of target drifts in the uncertainty plane.

description: Location planning is crucial to a company’s long-term success. The increasing concentration of companies in urban areas poses new challenges for regional location planning. For companies to make good long-term location planning and development decisions, they must increasingly cooperate with Economic Development Agencies (EDAs). Against this background, a tool was developed in the DFG research project "TransferMetroPlant" that supports companies in regional location assessment and decision-making by comparing location requirements with assessed and stored locations. This tool makes it possible for EDAs to systematically and objectively carry out location consultancy and to derive development measures for the managed locations in the process. Company and municipal measures for the development of locations over time can be taken into account. This paper presents the structure of the tool and the corresponding workflow and provides insights into its development. In addition, essential findings of the workshop-based validation of the developed planning approach are described.

description: We present a method for measurements of electric dipole moments on (sub)-mm size (basalt) particles levitated in an acoustic trap and centered within a plate capacitor. If an electric field is applied the particles oscillate with specific frequencies due to their permanent dipole moments. We observe dipole moments on the order of $D_P = 10^{-15} ... 10^{-14} \rm \, C \, m $. The dipole moment increases in small aggregates with the number of grains and is larger for samples vibrated (tribocharged) before trapping. The basalt grains show no sign of change in their dipole moment during measurements, implying a timescale for charge mobility being at least larger than minutes.

description: We realize simultaneous quantum degeneracy in mixtures consisting of the alkali and alkalineearth-like atoms Li and Yb. This is accomplished within an optical trap by sympathetic cooling of the fermionic isotope 6Li with evaporatively cooled bosonic 174Yb and, separately, fermionic 173Yb.Using cross-thermalization studies, we also measure the elastic s-wave scattering lengths of both Li-Yb combinations, |a6Li-174Yb| = 1.0\pm0.2 nm and |a6Li-173Yb| = 0.9\pm0.2 nm. The equality of these lengths is found to be consistent with mass-scaling analysis. The quantum degenerate mixtures of Li and Yb, as realized here, can be the basis for creation of ultracold molecules with electron spin degrees of freedom, studies of novel Efimov trimers, and impurity probes of superfluid systems.

Effect of Bjerrum pairs on electrostatic properties in an electrolyte solution near charged surfaces: A mean-field approach

description: In this paper, we investigate the consequences of ion association, coupled with the considerations of finite size effects and orientational ordering of Bjerrum pairs as well as ions and water molecules, on electric double layer near charged surfaces. Based on the lattice statistical mechanics accounting for finite sizes and dipole moments of ions, Bjerrum pairs and solvent molecules, we consider the formation of Bjerrum pairs and derive the mathematical expressions for Bjerrum pair number density as well as cation/anion number density and water molecule number density. We reveal the several significant phenomena. Firstly, it is shown that our approach naturally yields the equilibrium constant for dissociation-association equilibrium between Bjerrum pairs and ions. Secondly, at low surface charge densities, an increase in the bulk concentration of Bjerrum pairs enhances the permittivity and decreases the differential capacitance. Next, for cases where Bjerrum pairs in an alcohol electrolyte solution have a high value of dipole moment, Bjerrum pair number density increases with decreasing distance from the charged surface, and differential capacitance and permittivity is high compared to ones for the cases with lower values of Bjerrum-pair dipole moments. Finally, we show that the difference in concentration and dipole moment of Bjerrum pairs can lead to some variation in osmotic pressure between two similarly charged surfaces.

Atypical antipsychotic treatment among immigrant and non-immigrant pediatric patients with attention deficit/hyperactivity disorder in British Columbia
Creators: name: Emode, Monica
Publisher: name: University of British Columbia
Year: 2022

description: This thesis is focused on characterizing differences in pharmacological treatment among immigrant and non-immigrant children with Attention-Deficit/Hyperactivity Disorder (ADHD). Multimodal approaches combining psychosocial and pharmacological interventions are recommended for the treatment of ADHD. Among pharmacological treatments, stimulant medications are among the most common and efficacious drug therapy used to manage ADHD symptoms. However, there are concerns around increasing use of medications, such as atypical antipsychotics, that lack substantive evidence and are not currently approved by Health Canada for the treatment of ADHD. This thesis has two main studies: First, scoping review methodology was used to examine longitudinal trends, prevalence, tolerability, and safety of atypical antipsychotics among children with ADHD. No studies were identified relating to atypical antipsychotic use specific to immigrant children with ADHD, even though this review found that many children with ADHD still receive atypical antipsychotics. Atypical antipsychotic medications are often used to manage psychiatric comorbidity and/or aggressive and impulsive symptoms associated with ADHD. However, there is little evidence regarding the safety and tolerability of atypical antipsychotics to support the use of these medications as a first-line intervention among children diagnosed with ADHD. Second, differences in first-line stimulant and atypical antipsychotic prescribing practices were examined among newly diagnosed immigrant and non-immigrant children with ADHD, living in British Columbia, Canada. Immigrant children were less likely than non-immigrant children to be dispensed a stimulant medication prescription in the 30-days following an incident diagnosis of ADHD. Among children, being older, male, and receiving treatment from a psychiatrist was associated with being dispensed an atypical antipsychotic prescription as a first-line intervention within 30-days of diagnosis. A latent class analysis (LCA) was conducted to account for sources of variability that may be associated with ADHD treatment. A high proportion of children with ADHD were not dispensed any prescription medications. Non-migrant boys had a 68% increased likelihood of being treated with atypical antipsychotics compared to their migrant counterparts. Together, the studies incorporated in this thesis underline the importance of examining relationships between structural determinants of health, health equity, and ADHD-related prescribing practices.
Ion partitioning effect on the electrostatic interaction between two charged soft surfaces

description: We theoretically investigate electrostatic properties between two charged surfaces with a grafted polyelectrolyte layer in an aqueous electrolyte solution by using the Poisson-Boltzmann approach accounting for ion partitioning. In order to consider the ion partitioning effect, we focus on changes of electrostatic properties due to the difference in dielectric permittivity of the polyelectrolyte layer and the aqueous electrolyte solution. We find that ion partitioning enhances electrostatic potential in the region between two charged soft surfaces and hence increases the electrostatic interaction between two charged soft surfaces. Ion partitioning effect on osmotic pressure is enhanced not only by an increase in the thickness of polyelectrolyte layer and Debye length but also by a decrease in ion radius.

description: Gravitational lensing induces significant errors in the measured distances to high-redshift standard candles and standard sirens such as type-Ia supernovae, gamma-ray bursts, and merging supermassive black hole binaries. There will therefore be a significant benefit from correcting for the lensing error by using independent and accurate estimates of the lensing magnification. We investigate how accurately the magnification can be inferred from convergence maps reconstructed from galaxy shear and flexion data. We employ ray-tracing through the Millennium Simulation to simulate lensing observations in large fields, and perform a weak-lensing reconstruction on these fields. We identify optimal ways to filter the reconstructed convergence maps and to convert them to magnification maps. We find that a shear survey with 100 galaxies/arcmin^2 can help to reduce the lensing-induced distance errors for standard candles/sirens at redshifts z=1.5 (z=5) on average by 20% (10%), whereas a futuristic survey with shear and flexion estimates from 500 galaxies/arcmin^2 yields much larger reductions of 50% (35%). For redshifts z>=3, a further improvement by 5% can be achieved, if the individual redshifts of the galaxies are used in the reconstruction. Moreover, the reconstruction allows one to identify regions for which the convergence is low, and in which an error reduction by up to 75% can be achieved.

description: Understanding point cloud has recently gained huge interests following the development of 3D scanning devices and the accumulation of large-scale 3D data. Most point cloud processing algorithms can be classified as either point-based or voxel-based methods, both of which have severe limitations in processing time or memory, or both. To overcome these limitations, we propose Projection-based Point Convolution (PPConv), a point convolutional module that uses 2D convolutions and multi-layer perceptrons (MLPs) as its components. In PPConv, point features are processed through two branches: point branch and projection branch. Point branch consists of MLPs, while projection branch transforms point features into a 2D feature map and then apply 2D convolutions. As PPConv does not use point-based or voxel-based convolutions, it has advantages in fast point cloud processing. When combined with a learnable projection and effective feature fusion strategy, PPConv achieves superior efficiency compared to state-of-the-art methods, even with a simple architecture based on PointNet++. We demonstrate the efficiency of PPConv in terms of the trade-off between inference time and segmentation performance. The experimental results on S3DIS and ShapeNetPart show that PPConv is the most efficient method among the compared ones. The code is available at github.com/pahn04/PPConv.

description: We extend the recently proposed Kerr/CFT correspondence to examine the dual conformal field theory of Kaluza-Klein black hole. For the extremal Kaluza-Klein black hole, the central charge and temperature of the dual conformal field are calculated, and the microscopic entropy calculated by using Cardy formula agrees with the Bekenstein-Hawking entropy of extremal Kaluza-Klein black hole. For the non-extremal case, we investigate the hidden conformal symmetry of Kaluza-Klein black hole by studying the near-region wave equation of a neutral massless scalar field, and find the left and right temperatures of dual conformal field theory. Furthermore, the entropy of non-extremal Kaluza-Klein black hole is reproduced by using Cardy formula.

description: In this paper, we study the problem of enabling a vision-based robotic manipulation system to generalize to novel tasks, a long-standing challenge in robot learning. We approach the challenge from an imitation learning perspective, aiming to study how scaling and broadening the data collected can facilitate such generalization. To that end, we develop an interactive and flexible imitation learning system that can learn from both demonstrations and interventions and can be conditioned on different forms of information that convey the task, including pre-trained embeddings of natural language or videos of humans performing the task. When scaling data collection on a real robot to more than 100 distinct tasks, we find that this system can perform 24 unseen manipulation tasks with an average success rate of 44%, without any robot demonstrations for those tasks.

Formation of the black-hole binary M33 X-7 via mass-exchange in a tight massive system

description: M33 X-7 is among the most massive X-Ray binary stellar systems known, hosting a rapidly spinning 15.65 Msun black hole orbiting an underluminous 70 Msun Main Sequence companion in a slightly eccentric 3.45 day orbit. Although post-main-sequence mass transfer explains the masses and tight orbit, it leaves unexplained the observed X-Ray luminosity, star's underluminosity, black hole's spin, and eccentricity. A common envelope phase, or rotational mixing, could explain the orbit, but the former would lead to a merger and the latter to an overluminous companion. A merger would also ensue if mass transfer to the black hole were invoked for its spin-up. Here we report that, if M33 X-7 started as a primary of 85-99 Msun and a secondary of 28-32 Msun, in a 2.8-3.1 day orbit, its observed properties can be consistently explained. In this model, the Main Sequence primary transferred part of its envelope to the secondary and lost the rest in a wind; it ended its life as a ~16 Msun He star with a Fe-Ni core which collapsed to a black hole (with or without an accompanying supernova). The release of binding energy and, possibly, collapse asymmetries "kicked" the nascent black hole into an eccentric orbit. Wind accretion explains the X-Ray luminosity, while the black hole spin can be natal.

description: In this study, a novel sorbent, 1-octyl-3-methylimidazolium hexafluorophosphate functionalised magnetic poly β-cyclodextrin, was successfully synthesised and applied to magnetic solid-phase extraction for the determination of pyrethroids in tea infusions. The sorbent was characterised by transmission electron microscopy, energy-dispersive spectroscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, vibrating sample magnetometer and Brunauer–Emmett–Teller measurement. All factors affecting extraction efficiency, such as sorbent amount, extraction time, ionic strength and desorption conditions, were optimised individually. Under the chosen conditions, wide linearity (2.5–500 μg L−1) with determination coefficients ranging from 0.9995 to 0.9999, low limits of detection of 0.32–0.54 μg L−1 and good precision (intra-day: 2.6–7.0%; inter-day: 3.5–7.6%) were achieved for four pyrethroids in tea infusions. The relative recoveries of target analytes in real tea infusion samples were from 70% to 101% with relative standard deviations lower than 9.1%. We conclude that the proposed method is promising in the detection of pyrethroids in tea infusions.

description: This work is devoted to review the gauge embedding of either commutative and noncommutative (NC) theories using the symplectic formalism framework. To sum up the main features of the method, during the process of embedding, the infinitesimal gauge generators of the gauge embedded theory are easily and directly chosen. Among other advantages, this enables a greater control over the final Lagrangian and brings some light on the so-called "arbitrariness problem". This alternative embedding formalism also presents a way to obtain a set of dynamically dual equivalent embedded Lagrangian densities which is obtained after a finite number of steps in the iterative symplectic process, oppositely to the result proposed using the BFFT formalism. On the other hand, we will see precisely that the symplectic embedding formalism can be seen as an alternative and an efficient procedure to the standard introduction of the Moyal product in order to produce in a natural way a NC theory. In order to construct a pedagogical explanation of the method to the nonspecialist we exemplify the formalism showing that the massive NC U(1) theory is embedded in a gauge theory using this alternative systematic path based on the symplectic framework. Further, as other applications of the method, we describe exactly how to obtain a Lagrangian description for the NC version of some systems reproducing well known theories. Naming some of them, we use the procedure in the Proca model, the irrotational fluid model and the noncommutative self-dual model in order to obtain dual equivalent actions for these theories. To illustrate the process of noncommutativity introduction we use the chiral oscillator and the nondegenerate mechanics.

description: We study resonant tunneling through a superconducting double barrier structure in graphene as a function of the system parameters. At each barrier, due to the proximity effect, an incident electron can either reflect as an electron or a hole (specular as well as retro Andreev reflection in graphene). Similarly, transport across the barriers can occur via electrons as well as via the crossed (specular and/or retro) Andreev channel, where a hole is transmitted nonlocally to the other lead. In this geometry, in the subgap regime, we find resonant suppression of Andreev reflection at certain energies, due to the formation of Andreev bound levels between the two superconducting barriers, where the transmission probability T for electrons incident on the double barrier structure becomes unity. The evolution of the transport through the superconducting double barrier geometry as a function of the incident energy for various angles of incidence shows the damping of the resonance as normal reflection between the barriers increases.

description: The reactions between ozone and indoor unsaturated lipid films leads to the formation of products with negative health effects. Although much work has been conducted to study the ozone chemistry in unsaturated lipid films, little research has focused on the phase behavior of the films during ozonolysis, which is critical in understanding the kinetics and effects of the corresponding reactions. Here we show that a second phase will form during the ozonolysis of six kinds of unsaturated lipid droplets relevant for indoors (squalene, triolein, oleic acid, a skin oil proxy and canola oil) after several hours of exposure to 700-850 ppb of ozone under two different relative humidity (RH) ranges, 4.5 -6.5 % and 50 -65 %. For triolein, oleic acid and canola oil, a clear second phase formed under the same exposure time regardless of the RH, while an extended exposure time was required to form a second phase for squalene and a skin oil proxy at higher RH compared to low RH. Subsequent melting tests showed that the temperatures for the onset and completion of melting of the second phase were higher for the droplets oxidized at low RH compared to those oxidized at higher RH. Oligomers and polymers formed from secondary ozonolysis reactions are proposed as key components of the second phase. Finally, our observations were used to predict the formation of a second phase in real indoor organic films. Our work suggests that a second phase is most likely to form in skin oil films and cooling oil films indoors due to ozonolysis.
