description: The Breakthrough Listen Initiative, as part of its larger mission, is performing the most thorough technosignature search of nearby stars. Additionally, Breakthrough Listen is collaborating with scientists working on NASAs Transiting Exoplanet Survey Satellite (TESS), to examine TESS Targets of Interest (TOIs) for technosignatures. Here, we present a $1-11$ $\textrm{GHz}$ radio technosignature search of $61$ TESS TOIs that were in transit during their Breakthrough Listen observation at the Robert C. Byrd Green Bank Telescope. We performed a narrowband Doppler drift search with a minimum S/N threshold of $10$, across a drift rate range of $\pm 4$ $\textrm{Hz}$ $\textrm{s}$ $^{-1}$, with a resolution of $3$ $\textrm{Hz}$. We removed radio frequency interference by comparing signals across cadences of target sources. After interference removal, there are no remaining events in our survey, and therefore no technosignature signals-of-interest detected in this work. This null result implies that at L, S, C, and X bands, fewer than $52\textrm{%}$, $20\textrm{%}$, $16\textrm{%}$, and $15\textrm{%}$, respectively, of TESS TOIs possess a transmitter with an equivalent isotropic radiated power greater than a few times $10^{14}$ $\textrm{W}$.

description: To temporally localize a signal in a signal stream in noisy environments, it is necessary to identify a suitable transformation that suppresses the noise-floor and amplifies the signal sections. In this computational test, different combinations of the discrete-time signal x and its transformation result y are convolved with a moving non-causal Dirichlet window. The transformation used here is the signal’s approximate derivative with respect to time.The test aims to determine which combination of input data leads to the highest amplitude ratio between the noise floor and the signal section.

description: We investigate the quantum state transfer in a chain of particles satisfying q-deformed oscillators algebra. This general algebraic setting includes the spin chain and the bosonic chain as limiting cases. We study conditions for perfect state transfer depending on the number of sites and excitations on the chain. They are formulated by means of irreducible representations of a quantum algebra realized through Jordan-Schwinger maps. Playing with deformation parameters, we can study the effects of nonlinear perturbations or interpolate between the spin and bosonic chain.

description: Design practices are being implemented to address wicked problems in healthcare but are underutilised in assistive technology. This thesis explores how to improve assistive technology outcomes through collaboration between people with lived experience of disability, occupational therapists and design professionals. The findings demonstrate that assistive technology issues are wicked problems and that the current scope of practice for design within assistive technology is limited and may benefit from being extended to process and systemic levels. However, this must be tempered through genuine collaboration with people with lived experience of disability and leveraging the clinical experience of occupational therapists.

description: Based on large-scale molecular dynamics simulations, we propose a new charging method that should be capable of charging a Lithium-ion battery in a fraction of the time needed when using traditional methods. This charging method uses an additional applied oscillatory electric field. Our simulation results show that this charging method offers a great reduction in the average intercalation time for Li+ ions, which dominates the charging time. The oscillating field not only increases the diffusion rate of Li+ ions in the electrolyte but, more importantly, also enhances intercalation by lowering the corresponding overall energy barrier.

description: By applying the recently developed Loop Regularization(LR) with string-mode regulators to supersymmetric field theories, we explicitly verify the supersymmetric Ward identities in several supersymmetric models at one-loop level. It is interesting to observe that supersymmetry is a so remarkable symmetry that the supersymmetric Ward identities hold as long as a regularization scheme is realized in the exact four dimensional space-time with translational invariance for the momentum integration, and the gauge symmetry can be maintained once the regularization scheme preserves supersymmetry and satisfies the consistency condition for logarithmic divergences. As a manifest demonstration, we carry out a complete one-loop renormalization for the massive Wess-Zumino model by adopting the LR method, it is found that all the quadratic divergences cancel out and the relations among masses and coupling constants hold after renormalization, which agrees with the well-known non-renormalization theorem. It is concluded that the LR method preserves not only gauge symmetry but also supersymmetry. A simple and definite derivation of Majorana Feynman rules is found to be very useful.

Dissecting the roles of monolignol supply and oxidative enzymes in Arabidopsis thaliana lignification
Creators: name: Kuo, Chak Chung
Publisher: name: University of British Columbia
Year: 2024

description: Lignin is a rigid, hydrophobic polymer that strengthens the cell wall of supportive fibres and water-conducting vessels in vascular plants. Four main stages of lignification include: (1) monolignol production in the cytosol via the phenylpropanoid pathway, activated by MYB58 and MYB63 transcription factors; (2) monolignol diffusion into the cell wall; (3) monolignol radicalization by laccases (LACs) and/or peroxidases (PRXs); and (4) radical coupling of monolignols into polymeric lignin. Disrupting monolignol production or mutating oxidative enzymes often leads to improper plant development or dwarfism, suggesting that the quantity and location of lignin in the cell wall must be tightly regulated. It remains unclear how plants balance monolignol production and oxidative enzyme activity to coordinate proper lignification and plant development. In this study, Arabidopsis plants that overexpress MYB63 in xylem vessels and interfascicular fibres have increased stem lignin content without growth penalty. This suggests that a moderate increase in metabolic flux through the phenylpropanoid pathway leads to hyperlignification in lignifying cell types that possess the necessary molecular machinery for lignification. To understand how oxidative enzymes in distinct cell wall domains contribute to lignification, higher order mutants of LACs and PRXs were created with CRISPR/Cas9. Mutating genes encoding secondary cell wall-localized LAC4, LAC17, and PRX72 led to more irregular vessels and less stem lignin than the lac4-2 lac17 double mutant without additional growth penalty; mutating genes encoding cell corner/middle lamella-localized LAC4 and PRX64 led to shorter stems compared to the lac4-2 single mutant. This suggests that vessel irregularity does not contribute to lignin modification-induced dwarfism. The ability to modulate the quantity and distribution of lignin without growth penalty will provide insights into engineering low-lignin plants for more efficient conversion of cellulose to biofuels, and high-lignin plants for valuable phenolic-derived bioproducts.

description: We have studied the centrality bin size dependence of charged particle forward-backward multiplicity correlation strength in 5%, 0-5%, and 0-10% most central Au+Au collisions at $\sqrt{s_NN}}$=200 GeV with a parton and hadron cascade model, PACIAE based on PYTHIA. The real (total), statistical, and NBD (Negative Binomial Distribution) correlation strengths are calculated by the real events, the mixed events, and fitting the charged particle multiplicity distribution to the NBD, respectively. It is turned out that the correlation strength increases with increasing centrality bin size monotonously. If the discrepancy between real (total) and statistical correlation strengths is identified as dynamical one, the dynamical correlation may just be a few percent of the total (real) correlation.

description: We study charge and energy transport in a quasi-1D magnetic wire in the presence of magnetic textures. The energy flows can be expressed in a fashion similar to charge currents, leading to new energy-current induced spin torques. In analogy to charge currents, we can identify two reciprocal effects: spin-transfer torque on the magnetic order parameter induced by energy current and the Berry-phase gauge field induced energy flow. In addition, we phenomenologically introduce new $β-$like viscous coupling between magnetic dynamics and energy current into the LLG equation, which originates from spin mistracking of the magnetic order. We conclude that the new viscous term should be important for the thermally induced domain wall motion. We study the interplay between charge and energy currents and find that many of the effects of texture motion on the charge currents can be replicated with respect to energy currents. For example, the moving texture can lead to energy flows which is an analogue of the electromotive force in case of charge currents. We suggest a realization of cooling effect by magnetic texture dynamics.

description: A method is proposed for generating compact fractal disordered media, by generalizing the random midpoint displacement algorithm. The obtained structures are invasive stochastic fractals, with the Hurst exponent varying as a continuous parameter, as opposed to lacunar deterministic fractals, such as the Menger sponge. By employing the Detrending Moving Average algorithm [Phys. Rev. E 76, 056703 (2007)], the Hurst exponent of the generated structure can be subsequently checked. The fractality of such a structure is referred to a property defined over a three dimensional topology rather than to the topology itself. Consequently, in this framework, the Hurst exponent should be intended as an estimator of compactness rather than of roughness. Applications can be envisaged for simulating and quantifying complex systems characterized by self-similar heterogeneity across space. For example, exploitation areas range from the design and control of multifunctional self-assembled artificial nano and micro structures, to the analysis and modelling of complex pattern formation in biology, environmental sciences, geomorphological sciences, etc.

description: We provide linear-time algorithms for geometric graphs with sublinearly many crossings. That is, we provide algorithms running in O(n) time on connected geometric graphs having n vertices and k crossings, where k is smaller than n by an iterated logarithmic factor. Specific problems we study include Voronoi diagrams and single-source shortest paths. Our algorithms all run in linear time in the standard comparison-based computational model; hence, we make no assumptions about the distribution or bit complexities of edge weights, nor do we utilize unusual bit-level operations on memory words. Instead, our algorithms are based on a planarization method that "zeroes in" on edge crossings, together with methods for extending planar separator decompositions to geometric graphs with sublinearly many crossings. Incidentally, our planarization algorithm also solves an open computational geometry problem of Chazelle for triangulating a self-intersecting polygonal chain having n segments and k crossings in linear time, for the case when k is sublinear in n by an iterated logarithmic factor.

description: Time-dependent energy spectra of galactic cosmic rays (GCRs) carry fundamental information regarding their origin and propagation. When observed at the Earth, these spectra are significantly affected by the solar wind and the embedded solar magnetic field that permeates the heliosphere, changing significantly over an 11-year solar cycle. Energy spectra of GCRs measured during different epochs of solar activity provide crucial information for a thorough understanding of solar and heliospheric phenomena. The PAMELA experiment had collected data for almost ten years (15th June 2006 - 23rd January 2016), including the minimum phase of solar cycle 23 and the maximum phase of solar cycle 24. In this paper, we present new spectra for helium nuclei measured by the PAMELA instrument from January 2010 to September 2014 over a three Carrington rotation time basis. These data are compared to the PAMELA spectra measured during the previous solar minimum providing a picture of the time dependence of the helium nuclei fluxes over a nearly full solar cycle. Time and rigidity dependencies are observed in the proton-to-helium flux ratios. The force-field approximation of the solar modulation was used to relate these dependencies to the shapes of the local interstellar proton and helium-nuclei spectra.

description: In this work we use variational inference to quantify the degree of uncertainty in deep learning model predictions of radio galaxy classification. We show that the level of model posterior variance for individual test samples is correlated with human uncertainty when labelling radio galaxies. We explore the model performance and uncertainty calibration for different weight priors and suggest that a sparse prior produces more well-calibrated uncertainty estimates. Using the posterior distributions for individual weights, we demonstrate that we can prune 30% of the fully-connected layer weights without significant loss of performance by removing the weights with the lowest signal-to-noise ratio. A larger degree of pruning can be achieved using a Fisher information based ranking, but both pruning methods affect the uncertainty calibration for Fanaroff-Riley type I and type II radio galaxies differently. Like other work in this field, we experience a cold posterior effect, whereby the posterior must be down-weighted to achieve good predictive performance. We examine whether adapting the cost function to accommodate model misspecification can compensate for this effect, but find that it does not make a significant difference. We also examine the effect of principled data augmentation and find that this improves upon the baseline but also does not compensate for the observed effect. We interpret this as the cold posterior effect being due to the overly effective curation of our training sample leading to likelihood misspecification, and raise this as a potential issue for Bayesian deep learning approaches to radio galaxy classification in future.

description: We analyze the full counting statistics (FCS) of a single-site quantum dot coupled to a local Holstein phonon for arbitrary transmission and weak electron-phonon coupling. We identify explicitly the contributions due to quasielastic and inelastic transport processes in the cumulant generating function and discuss their influence on the transport properties of the dot. We find that in the low-energy sector, the inelastic term causes a sign change in the shot noise correction at certain universal values of the transmission. Furthermore, we show that when the correction to the current due to inelastic processes vanishes, all odd order cumulants vanish as well.

micro-assembly technology

description: Micro-Transfer-Printing (μTP) as an alternative micro-assembly technology opens up new possibilities in the integration and packaging of smart devices like processed III/V devices, optical filters and special sensors on CMOS and MEMS on wafer-level. The technology uses an elastomer stamp to manipulate multiple printable components at the same time that are difficult to handle because of their size or fragility. Nevertheless, the industrial application of this technology as well as the transfer and upscaling from laboratory scale is still challenging. In order to realize a reliable printing process with sufficient yield, the interaction of the components to be printed, their fixation by tether structures to the source wafer and the adhesion of the transfer stamp must be well adapted. Therefore, the presented work will deal with results of mechanical experiments and FEA-modelling in order to get a deeper understanding of the μTP-process and will allow a defined tether layout and optimization of the processed source wafers.

description: A quantitative spectral analysis of BA-type supergiants and bright giants in an inner spiral arm region of the nearby spiral galaxy NGC 300 is presented, based on observations with the Multi Unit Spectroscopic Explorer (MUSE) on the European Southern Obsevatory, Very Large Telescope (ESO, VLT). The flux-weighted gravity-luminosity relationship (FGLR), a stellar spectroscopic distance determination method for galaxies, is extended towards stars at lower luminosities. Point spread function fitting 3D spectroscopy was performed with PampelMUSE on the datacube. The 16 stars with the highest signal-to-noise ratios ($S/N s$) are classified with regard to their spectral type and luminosity class using Galactic templates. They were analysed using hybrid non-local thermodynamic equilibrium (non-LTE) model spectra to fit the strongest observed hydrogen, helium, and metal lines in the intermediate-resolution spectra. Supplemented by photometric data, this facilitates fundamental stellar parameters and interstellar reddening which have yet to be determined. Effective temperatures, surface gravities, reddening $E(B-V)$, bolometric magnitudes and luminosities, as well as radii and masses are presented for the sample stars. The majority of the objects follow the FGLR as established from more luminous BA-type supergiants in NGC 300. An increase in the scatter in the flux-weighted gravity-luminosity plane is observed at these lower luminosities, which is in line with predictions from population synthesis models.

description: Molecular line emission is a powerful probe of the physical conditions of astrophysical objects but can be complex to model, and it is often unclear which transitions would be the best targets for observers who wish to constrain a given parameter. We therefore produce a list of molecular species for which the gas history can be ignored, removing a major modelling complexity. We then determine the best of these species to observe when attempting to constrain various physical parameters. To achieve this, we use a large set of chemical models with different chemical histories to determine which species have abundances at 1 MYr that are insensitive to the initial conditions. We then use radiative transfer modelling to produce the intensity of every transition of these molecules. We finally compute the mutual information between the physical parameters and all transitions and transition ratios in order to rank their usefulness in determining the value of a given parameter. We find 48 species that are insensitive to the chemical history of the gas, 23 of which have collisional data available. We produce a ranked list of all the transitions and ratios of these species using their mutual information with various gas properties. We show mutual information is an adequate measure of how well a transition can constrain a physical parameter by recovering known probes and demonstrating that random forest regression models become more accurate predictors when high-scoring features are included. Therefore, this list can be used to select target transitions for observations in order to maximize knowledge about those physical parameters.

The COPE HCW trial : evaluating the engagement of healthcare workers in an mHealth exercise app intervention
Creators: name: McKenna, Julia
Publisher: name: University of British Columbia
Year: 2024

description: Background: The COVID-19 pandemic has exacerbated symptoms of stress, burnout, depression, and anxiety among healthcare workers (HCWs). Physical activity (PA) improves mental and physical health; it can be used as a coping strategy by individuals experiencing high levels of stress and poor mental health. Research has investigated the use of mobile health (mHealth) interventions to promote PA. The COVID-19 Pandemic and exercise for healthcare workers (COPE HCW) trial was a novel 12-week mHealth exercise intervention tailored to HCWs using a suite of at-home exercise apps. Very few studies have investigated or evaluated the engagement in an mHealth exercise intervention among HCWs, and studies have rarely used qualitative methods to examine engagement in such interventions. Using the Capability-Opportunity-Motivation-Behavior (COM-B) model and Diffusion of Innovation (DoI) theory, this study explores the following research questions: 1) How well did the COPE HCW intervention address capability, opportunity and motivation for individuals demonstrating different engagement profiles? 2) What DoI attributes of the COPE HCW intervention were associated with engagement in the trial? 3) What can be learned from applying these theories to understanding engagement in mHealth interventions? Methods: One-on-one semi-structured interviews were conducted via Zoom with 25 HCWs in British Columbia who recently completed the COPE HCW trial. Interviews were analyzed through reflexive thematic analysis methods. Results: Both high and low engagers shared similar themes with regards to compatibility, complexity, relative advantage, observability, and trialability. Motivation was the main factor differentiating high and low engagers; most particularly, intention to exercise. Other differences were noted among shift and non-shift workers, as shift workers expressed reduced energy and opportunity to engage in exercise. Discussion: COM-B and DoI are complementary theories that serve as an effective approach in evaluating engagement in an mHealth intervention. While mHealth apps provide many factors to facilitate easier engagement in exercise, user engagement with an app may depend on individual motivation. Future interventions should employ counselling or motivational interviewing techniques in conjunction with the use of mHealth apps to support behaviour change.

description: We present an improved analysis of the final dataset from the QUaD experiment. Using an improved technique to remove ground contamination, we double the effective sky area and hence increase the precision of our CMB power spectrum measurements by ~30% versus that previously reported. In addition, we have improved our modeling of the instrument beams and have reduced our absolute calibration uncertainty from 5% to 3.5% in temperature. The robustness of our results is confirmed through extensive jackknife tests and by way of the agreement we find between our two fully independent analysis pipelines. For the standard 6-parameter LCDM model, the addition of QUaD data marginally improves the constraints on a number of cosmological parameters over those obtained from the WMAP experiment alone. The impact of QUaD data is significantly greater for a model extended to include either a running in the scalar spectral index, or a possible tensor component, or both. Adding both the QUaD data and the results from the ACBAR experiment, the uncertainty in the spectral index running is reduced by ~25% compared to WMAP alone, while the upper limit on the tensor-to-scalar ratio is reduced from r < 0.48 to r < 0.33 (95% c.l). This is the strongest limit on tensors to date from the CMB alone. We also use our polarization measurements to place constraints on parity violating interactions to the surface of last scattering, constraining the energy scale of Lorentz violating interactions to < 1.5 x 10^{-43} GeV (68% c.l.). Finally, we place a robust upper limit on the strength of the lensing B-mode signal. Assuming a single flat band power between l = 200 and l = 2000, we constrain the amplitude of B-modes to be < 0.57 micro-K^2 (95% c.l.).

Density depletion and enhanced fluctuations in water near hydrophobic solutes: identifying the underlying physics

description: We investigate the origin of the density depletion and enhanced density fluctuations that occur in water in the vicinity of an extended hydrophobic solute. We argue that both phenomena are remnants of the critical drying surface phase transition that occurs at liquid-vapor coexistence in the macroscopic planar limit, ie. as the solute radius $R_s\to\infty$. Focusing on the density profile $ρ(r)$ and a sensitive spatial measure of fluctuations, the local compressibility profile $χ(r)$, we develop a scaling theory which expresses the extent of the density depletion and enhancement in compressibility in terms of $R_s$, the strength of solute-water attraction $\varepsilon_s$, and the deviation from liquid-vapor coexistence $δμ$. Testing the predictions against results of classical density functional theory for a simple solvent and Grand Canonical Monte Carlo simulations of a popular water model, we find that the theory provides a firm physical basis for understanding how water behaves at a hydrophobe.

description: Formal specification languages have long languished, due to the grave scalability problems faced by complete verification methods. Runtime verification promises to use formal specifications to automate part of the more scalable art of testing, but has not been widely applied to real systems, and often falters due to the cost and complexity of instrumentation for online monitoring. In this paper we discuss work in progress to apply an event-based specification system to the logging mechanism of the Mars Science Laboratory mission at JPL. By focusing on log analysis, we exploit the "instrumentation" already implemented and required for communicating with the spacecraft. We argue that this work both shows a practical method for using formal specifications in testing and opens interesting research avenues, including a challenging specification learning problem.

description: The spreading of Covid-19 pandemic has highlighted the close link between economics and health in the context of emergency management. A widespread vaccination campaign is considered the main tool to contain the economic consequences. This paper will focus, at the level of wealth distribution modelling, on the economic improvements induced by the vaccination campaign in terms of its effectiveness rate. The economic trend during the pandemic is evaluated resorting to a mathematical model joining a classical compartmental model including vaccinated individuals with a kinetic model of wealth distribution based on binary wealth exchanges. The interplay between wealth exchanges and the progress of the infectious disease is realized by assuming on the one hand that individuals in different compartments act differently in the economic process and on the other hand that the epidemic affects risk in economic transactions. Using the mathematical tools of kinetic theory, it is possible to identify the equilibrium states of the system and the formation of inequalities due to the pandemic in the wealth distribution of the population. Numerical experiments highlight the importance of the vaccination campaign and its positive effects in reducing economic inequalities in the multi-agent society.

description: We extend de Finetti's [Ann. Inst. H. Poincaré 7 (1937) 1--68] notion of exchangeability to finite and countable sequences of variables, when a subject's beliefs about them are modelled using coherent lower previsions rather than (linear) previsions. We derive representation theorems in both the finite and countable cases, in terms of sampling without and with replacement, respectively.

description: Graphene antidot lattices have recently been proposed as a new breed of graphene-based superlattice structures. We study electronic properties of triangular antidot lattices, with emphasis on the occurrence of dispersionless (flat) bands and the ensuing electron localization. Apart from strictly flat bands at zero-energy (Fermi level), whose existence is closely related to the bipartite lattice structure, we also find quasi-flat bands at low energies. We predict the real-space electron density profiles due to these localized states for a number of representative antidot lattices. We point out that the studied low-energy, localized states compete with states induced by defects on the superlattice scale in this system which have been proposed as hosts for electron spin qubits. We furthermore suggest that local moments formed in these midgap zero-energy states may be at the origin of a surprising saturation of the electron dephasing length observed in recent weak localization measurements in graphene antidot lattices.

Meixner class of non-commutative generalized stochastic processes with freely independent values I. A characterization

description: Let $T$ be an underlying space with a non-atomic measure $σ$ on it (e.g. $T=\mathbb R^d$ and $σ$ is the Lebesgue measure). We introduce and study a class of non-commutative generalized stochastic processes, indexed by points of $T$, with freely independent values. Such a process (field), $ω=ω(t)$, $t\in T$, is given a rigorous meaning through smearing out with test functions on $T$, with $\int_T σ(dt)f(t)ω(t)$ being a (bounded) linear operator in a full Fock space. We define a set $\mathbf{CP}$ of all continuous polynomials of $ω$, and then define a con-commutative $L^2$-space $L^2(τ)$ by taking the closure of $\mathbf{CP}$ in the norm $\|P\|_{L^2(τ)}:=\|PΩ\|$, where $Ω$ is the vacuum in the Fock space. Through procedure of orthogonalization of polynomials, we construct a unitary isomorphism between $L^2(τ)$ and a (Fock-space-type) Hilbert space $\mathbb F=\mathbb R\oplus\bigoplus_{n=1}^\infty L^2(T^n,γ_n)$, with explicitly given measures $γ_n$. We identify the Meixner class as those processes for which the procedure of orthogonalization leaves the set $\mathbf {CP}$ invariant. (Note that, in the general case, the projection of a continuous monomial of oder $n$ onto the $n$-th chaos need not remain a continuous polynomial.) Each element of the Meixner class is characterized by two continuous functions $λ$ and $η\ge0$ on $T$, such that, in the $\mathbb F$ space, $ω$ has representation $ω(t)=\di_t^†+λ(t)\di_t^†\di_t+\di_t+η(t)\di_t^†\di^2_t$, where $\di_t^†$ and $\di_t$ are the usual creation and annihilation operators at point $t$.
