description: The Caenorhabditis Intervention Testing Program (CITP) is a multi-institutional program that seeks robust and reproducible pro-longevity interventions that are efficacious across genetically diverse cohorts in the Caenorhabditis genus. The project features a unique design in which multiple experimental replicates are collected by three different laboratories at discrete locations for all candidate compounds tested. To limit confounding factors that may influence experimental reproducibility, we develop standardized operating procedures (SOPs) for all experimental procedures. Here we provide the CITP SOP for the compound Metformin.
Photoacoustic analyzer for natural gas and short-chain hydrocarbon isotopologues
Creators: name: Bahr, Marc-Simon
Publisher: name: Zenodo
Year: 2025

description: The objective of this work is the development of a sensor based on photoacoustic spectroscopy (PAS) which, contrary to the usual field of application of PAS, namely the detection of trace gases, is capable of measuring concentrations of the main alkanes of natural gas as well as of main methane isotopologues. Knowledge of the natural gas composition, whose main part is methane (7599% onaverage), allows a variety of conclusions to be drawn, including its origin and energy content. Furthermore, knowledge of the main methane isotopologues shares of natural gas allows conclusions to be drawn regarding the natural gas maturity and the surrounding rock. The latter can be used to optimize the drilling technology. Since the absorption spectra of the main alkanes and isotopologues strongly overlap, the determination of the optimal wavelength of the laser source used is not trivial, as far as different molecule types have to be differentiated simultaneously. Therefore, a mathematical algorithm was developed which calculates the optimal wavelength based on the theoretical absorption spectra. The heart of the new sensor is an interband cascade laser (ICL), which emits in the mid-infrared range around 3.3 µm wavelength. By applying the injectioncurrent modulation, it is possible to achieve more precise measurement results in comparison to indirect modulation techniques. The behavior of the laser in this mode was initially unknown and has been analyzed in this work with a Michelson interferometer. Calibration mixtures were produced, using a self-developed gas mixer, whose photoacoustic spectra were calculated by the implemented digital signal processor (DSP) real-time signal processing, based on their photoacoustic signals. The resulting spectra were used to train the machine-learning algorithm Partial Least Squares Regression (PLSR), which subsequently determines the concentrations of the main methane isotopologues and the main alkanes, based on their photoacoustic spectra. The evaluation of the developed sensor was carried out on the basis of synthetic gas mixtures, as well as with the help of real natural gas samples from various sources. It could be shown that PAS is suitable to determine the main methane isotopologues and to analyze natural gas with respect to the composition of its main alkanes. The new sensor determines the composition of the main components of real natural gas samples based on PAS in real time, which enables continuous monitoring of the natural gas composition.

description: We present a combined theoretical and experimental study of spatio-temporal propagation effects in terahertz (THz) generation in gases using two-color ionizing laser pulses. The observed strong broadening of the THz spectra with increasing gas pressure reveals the prominent role of spatio-temporal reshaping and of a plasma-induced blue-shift of the pump pulses in the generation process. Results obtained from (3+1)-dimensional simulations are in good agreement with experimental findings and clarify the mechanisms responsible for THz emission.

description: We investigate the stability of theories in which Lorentz invariance is spontaneously broken by fixed-norm vector "aether" fields. Models with generic kinetic terms are plagued either by ghosts or by tachyons, and are therefore physically unacceptable. There are precisely three kinetic terms that are not manifestly unstable: a sigma model $(\partial_μA_ν)2$, the Maxwell Lagrangian $F_{μν}F^{μν}$, and a scalar Lagrangian $(\partial_μA^μ)2$. The timelike sigma-model case is well-defined and stable when the vector norm is fixed by a constraint; however, when it is determined by minimizing a potential there is necessarily a tachyonic ghost, and therefore an instability. In the Maxwell and scalar cases, the Hamiltonian is unbounded below, but at the level of perturbation theory there are fewer degrees of freedom and the models are stable. However, in these two theories there are obstacles to smooth evolution for certain choices of initial data.

description: Weiche und kollineare Annäherungen sind die grundlegenden Konzepte, woraus Partonschauer- simulationen gebaut werden. Infrarotsingularitäten müssen sorgfältig behandelt werden, um Querschnitte von nächst-führender Ordnung zu berechnen. Aktuelle Partonschauersimula- tionen implementieren die Iteration einer Emission, aber um sie mit Querschnitten höherer Ordnung zu vergleichen, ist ein Rahmen für zwei oder mehr Emissionen erforderlich. Die Ar- beit in dieser Dissertation konzentriert sich auf die Entwicklung eines solchen Rahmens zur Faktorisierung weicher und kollinearer Emissionen aus Mehrteilchenamplituden für zwei oder mehr Emissionen. Der erste Teil der Arbeit besteht darin, die kinematische Abbildung für den Einemissionsfall zu untersuchen und diese zu modifizieren, um einen globalen Rückstoß über eine Lorentztransformation einzuführen. Dann werden die Konzepte auf einen verall- gemeinerten Fall erweitert und ein Partitionierungsformalismus entwickelt, um verschiedene kollineare Sektoren zu trennen. Dadurch kann auch die Abbildung für mehrere Emissionen entwickelt und die entsprechende Faktorisierung des Phasenraums festgelegt werden. Als nächstes wird ein Beispiel für die neue Abbildung gemacht, angewendet auf den Fall mit zwei Emissionen, und wichtige Gegenprüfungen werden durchgeführt. Schließlich wird die Abbildung für den Einemissionsfall in den Herwig 7-Dipolschauer implementiert und mit der vorhandenen Abbildung und anderen Varianten verglichen. Dies zeigt das Potenzial für eine Verbesserung der Kinematik des Partonschauers.

Role of microRNAs in subperineurial glial development and blood-brain barrier formation
Creators: name: Paluri, Sravya
Publisher: name: University of British Columbia
Year: 2024

description: In Drosophila, permeability barriers maintain homeostasis and ensure proper functioning of different tissues. In the nervous system, the blood-brain/nerve barriers are crucial for neuronal function and for survival. A type of glial cell, subperineurial glia (SPG) forms these barriers in both the central and the peripheral nervous system. Neighboring SPG cells form septate junctions (SJs) to seal the barrier at the bicellular contact points and, along the contact point of three cells, tricellular junction (TCJ). To maintain barrier integrity, the proper development of SPG, the SJ and the TCJ structure are crucial however, the mechanisms involved in coordinating this process are unknown. We hypothesized that microRNAs might be playing a role in SPG development and in SJ and TCJ formation. In Chapter 2, we performed a genetic screen using microRNA-sponges to knockdown 120 microRNAs in SPG and analyzed SPG morphology. We found that the knockdown of only microRNA-125 resulted in SPG morphological defects. However, our verification analysis using a microRNA-125 knockout mutant exhibited no morphological defects, suggesting that our genetic screen resulted in false positive results in SPG. In Chapter 3, we found that the SJ proteins Kune-kune, Sinuous and Macroglobulin-complement related are present in glial SJ, and Gliotactin, Bark and M6 are present in glial TCJ. Additionally, we found that overexpression of microRNA-184 (known to regulate SJ and TCJ proteins) led to the disruption of SJ structure and affected the localization of SJ proteins but had no effect on TCJ protein localization. We hypothesized that these phenotypes might be attributed to microRNA-184 binding to its target SJ and TCJ mRNAs and lowering their levels. However, using qRT-PCR technique, we found that the mRNA levels of these proteins were unaffected, suggesting that microRNA-184 binds to target SJ proteins and translationally repress them. Overexpression of miR-184 led to larval locomotory defects and lethality with a compromised blood-brain barrier. Thus, microRNAiv 184 overexpression in SPG disrupts the SJ structure and compromises the barrier function. Overall, we found that microRNAs might not play a role in peripheral glial development but are crucial for regulation of the permeability barrier in glia.

description: In this article we consider diffeomorphism groups of manifolds with smooth boundary. We show that the diffeomorphism groups of the manifold and its boundary fit into a short exact sequence which admits local sections. In other words, they form an infinite-dimensional fibre bundle. Manifolds with boundary are of interest in numerical analysis and with a view towards applications in machine learning we establish controllability results for families of vector fields. This generalises older results due to Agrachev and Caponigro in the boundary-less case. Our results show in particular that the diffeomorphism group of a manifold with smooth boundary is generated by the image of the exponential map.

Short-duration lensing events: I. wide-orbit planets? free-floating low-mass objects? or high-velocity stars?

Publisher: name: arXiv
Year: 2009

subject: FOS: Physical sciences

description: Short duration lensing events tend to be generated by low-mass lenses or by lenses with high transverse velocities. Furthermore, for any given lens mass and speed, events of short duration are preferentially caused by nearby lenses (mesolenses) that can be studied in detail, or else by lenses so close to the source star that finite-source-size effects may be detected, yielding information about both the Einstein ring radius and the surface of the lensed star. Planets causing short-duration events may be in orbits with any orientation, and may have semimajor axes smaller than an AU, or they may reach the outer limits of their planetary systems, in the region corresponding to the Solar System's Oort Cloud. They can have masses larger than Jupiter's or smaller than Pluto's. Lensing therefore has a unique potential to expand our understanding of planetary systems. A particular advantage of lensing is that it can provide precision measurements of system parameters, including the masses of and projected separation between star and planet. We demonstrate how the parameters can be extracted and show that a great deal can be learned. For example, it is remarkable that the gravitational mass of nearby free-floating planet-mass lenses can be measured by complementing observations of a photometric event with deep images that detect the planet itself. A fraction of short events may be caused by high-velocity stars located within a kpc. Many high-velocity lenses are likely to be neutron stars that received large natal kicks. Other high-speed stars may be members of the halo population. Still others may be hypervelocity stars that have been ejected from the Galactic Center, or runaway stars escaped from close binaries, possibly including the progenitor binaries of Type Ia supernovae.

description: We consider a stochastic Susceptible-Exposed-Infected-Recovered (SEIR) epidemiological model. Through the use of a normal form coordinate transform, we are able to analytically derive the stochastic center manifold along with the associated, reduced set of stochastic evolution equations. The transformation correctly projects both the dynamics and the noise onto the center manifold. Therefore, the solution of this reduced stochastic dynamical system yields excellent agreement, both in amplitude and phase, with the solution of the original stochastic system for a temporal scale that is orders of magnitude longer than the typical relaxation time. This new method allows for improved time series prediction of the number of infectious cases when modeling the spread of disease in a population. Numerical solutions of the fluctuations of the SEIR model are considered in the infinite population limit using a Langevin equation approach, as well as in a finite population simulated as a Markov process.

description: We study the effects of periodic subthreshold pacemaker activity and time-delayed coupling on stochastic resonance over scale-free neuronal networks. As the two extreme options, we introduce the pacemaker respectively to the neuron with the highest degree and to one of the neurons with the lowest degree within the network, but we also consider the case when all neurons are exposed to the periodic forcing. In the absence of delay, we show that an intermediate intensity of noise is able to optimally assist the pacemaker in imposing its rhythm on the whole ensemble, irrespective to its placing, thus providing evidences for stochastic resonance on the scale-free neuronal networks. Interestingly thereby, if the forcing in form of a periodic pulse train is introduced to all neurons forming the network, the stochastic resonance decreases as compared to the case when only a single neuron is paced. Moreover, we show that finite delays in coupling can significantly affect the stochastic resonance on scale-free neuronal networks. In particular, appropriately tuned delays can induce multiple stochastic resonances independently of the placing of the pacemaker, but they can also altogether destroy stochastic resonance. Delay-induced multiple stochastic resonances manifest as well-expressed maxima of the correlation measure, appearing at every multiple of the pacemaker period. We argue that fine-tuned delays and locally active pacemakers are vital for assuring optimal conditions for stochastic resonance on complex neuronal networks.

description: We explore an ansatz for the QCD vacuum in the Coulomb gauge that describes gauge field fluctuations in presence of a weakly interacting gas of abelian monopoles. Such magnetic disorder leads to long-range correlations which are manifested through the area law for the Wilson loop. In particular we focus on the role of the residual monopole-monopole interactions in providing the mechanism for suppression of the gluon propagator at low-momenta which also leads to low momentum enhancement in the ghost propagator.

description: Theories of low-energy Lorentz violation by a fixed-norm "aether" vector field with two-derivative kinetic terms have a globally bounded Hamiltonian and are perturbatively stable only if the vector is timelike and the kinetic term in the action takes the form of a sigma model. Here we investigate the phenomenological properties of this theory. We first consider the propagation of modes in the presence of gravity, and show that there is a unique choice of curvature coupling that leads to a theory without superluminal modes. Experimental constraints on this theory come from a number of sources, and we examine bounds in a two-dimensional parameter space. We then consider the cosmological evolution of the aether, arguing that the vector will naturally evolve to be orthogonal to constant-density hypersurfaces in a Friedmann-Robertson-Walker cosmology. Finally, we examine cosmological evolution in the presence of an extra compact dimension of space, concluding that a vector can maintain a constant projection along the extra dimension in an expanding universe only when the expansion is exponential.

Our approach is based on techniques from operator theory and systems theory, and it allows us to study coupled systems by exploiting properties of the components, which are typically much simpler to analyse. As our main results we establish resolvent estimates and decay rates for abstract boundary-coupled systems. We illustrate the power of the general results by using them to obtain rates of energy decay in coupled systems of one-dimensional wave and heat equations, and in a wave equation with an acoustic boundary condition.

description: This case study focuses on the instructional design and outcomes of a virtual reality (VR) application for sepsis management in healthcare education. The instructional design of the VR sepsis application follows five principles adapted from Merrill’s instructional design theory and Bloom’s taxonomy. The VR simulation is structured to provide a coherent and realistic experience, with instructional materials and feedback incorporated to guide and support the learners. A pilot study was conducted with medical students on clinical placement. Participants experienced the VR sepsis simulation and completed a questionnaire using the Immersive Technology Evaluation Measure (ITEM) to assess their immersion, intrinsic motivation, cognitive load, system usability, and debrief feedback. Descriptive analysis of the data showed median scores indicating high immersion and presence, intrinsic motivation, and perceived learning. However, participants reported a moderately high cognitive load. Comparison with a neutral response to ITEM suggested that users had a significantly higher user experience (p <  0.05) in all domains. This case study highlights the potential of VR in healthcare education and its application in sepsis management. The findings suggest that the instructional design principles used in the VR application can effectively engage learners and provide a realistic learning experience. Further research and evaluation are necessary to assess the impact of VR on learning outcomes and its integration into healthcare education settings.

A new computationally fast and efficient method of deriving the signal is presented. This method allows the implementation of up to date parameterisations of acoustic attenuation in sea water and ice that now includes the effects of complex attenuation, where appropriate. The methods presented here have been used to compute and study the properties of the acoustic signals which would be expected from such interactions. A matrix method of parameterising the signals, which includes the expected fluctuations, is also presented. These methods are used to generate the expected signals that would be detected in acoustic UHE neutrino telescopes.

Covid-19 pandemic and exercise for healthcare workers (COPE HCW) trial : secondary analyses examining the effects of at-home exercise on healthcare workers' multidimensional well-being
Creators: name: Haight, Brook
Publisher: name: University of British Columbia
Year: 2024

description: Background. Current research on employee well-being largely entails focus on physical and mental health and illness, as well as functioning specific to the workplace. Yet, more recent conceptualizations of well-being extend beyond the presence or absence of health or illness to concepts of thriving or languishing, measured using an outcome-wide measurement approach. Accordingly, healthcare worker (HCW) multidimensional well-being as an overarching concept should be inclusive of a broad range of ill-being and well-being indictors that span multiple dimensions, including physical, psychological, and psychosocial realms of life. A recent 12- week mHealth exercise intervention for HCWs in Vancouver, BC demonstrated significant treatment effects for depressive symptoms, burnout symptoms, and absenteeism among those randomized to an exercise versus waitlist control condition. Secondary analyses were conducted to examine whether positive treatment effects could extend to a broader range of multidimensional ill-being and well-being outcomes. Methods. Data was from the COVID-19 Pandemic and Exercise for Healthcare Workers (COPE HCW) trial, a two-arm parallel randomized controlled trial for low-active HCWs working at Providence Health Care centers across Vancouver, BC. The effects of engagement with a suite of exercise applications for 80 minutes per week for 12 weeks (vs. waitlist control) on indicators of multidimensional ill-being and well-being were examined. Treatment effects for physical health symptoms, recent global stress, work-to-personal life interference, overall physical health, overall mental/emotional health, life satisfaction, psychological flourishing, resilience, and work- to-personal life enhancement were analyzed using intent-to-treat analyses with a structural equation modelling (SEM) growth model approach. Results. By the end of the trial, significant treatment effects were observed for all outcomes, such that those in the exercise condition (vs. waitlist control) reported significant reductions in ill-being and improvements in well-being measures. Adherence to the intervention decreased over time, and treatment effects were most apparent for those who engaged with the exercise apps the most. Conclusions. mHealth exercise is one individual-level behavioral intervention which was successful in improving multidimensional ill-being and well-being among HCWs. Findings will help inform future employee wellness programming by providing evidence that mHealth exercise can be used as a modality to support well-being across different life domains.

description: Moderate associations have been identified between gene expression and DNA methylation variability, predicted transcription factor binding sites, and transcription factor expression across multiple human tissues, including healthy mammary cells and diverse cancer-related cellular contexts. However, previous models summarized DNA methylation primarily at promoter regions, ignoring methylation variability in other genomic regions. In the current thesis, I propose using Variably Methylated Regions (VMRs) for summarizing DNA methylation and hypothesized that models trained on VMR-derived features would outperform promoter-centered models in the prediction of individual gene expression across healthy mammary cell types. Results largely supported this hypothesis, with VMR-based models demonstrating a superior capacity for predicting standardized individual gene expression across held-out samples compared to their promoter counterparts. Additionally, the DNA methylation feature showed the highest contribution to the performance of VMR-based models. Despite challenges in generalizing association patterns to unseen data across all regression models, this thesis is the first study that uses and rigorously evaluates the contribution of VMR-derived features to explain gene expression variability across healthy mammary cell types.

description: In this article we investigate the L^1-norm of certain functions on groups called divisibility functions. Using these functions, their connection to residual finiteness, and integration theory on profinite groups, we define the residual average of a finitely generated group. One of the main results in this article is the finiteness of residual averages on finitely generated linear groups. Whether or not the residual average is finite depends on growth rates of indices of finite index subgroups. Our results on index growth rates are analogous to results on gaps between primes, and provide a variant of the subgroup growth function, which may be of independent interest.

description: Due to the COVID-19 pandemic the virus responsible, SARS-CoV-2, became a source of intense interest for non-expert audiences. The viral spike protein gained particular public interest as the main target for protective immune responses, including those elicited by vaccines. The rapid evolution of SARS-CoV-2 resulted in variations in the spike that enhanced transmissibility or weakened vaccine protection. This created new variants of concern (VOCs). The emergence of VOCs was studied using viral sequence data which was shared through portals such as the online Mutation Explorer of the COVID-19 Genomics UK consortium (COG-UK/ME). This was designed for an expert audience, but the information it contained could be of general interest if suitably communicated. Visualisations, interactivity and animation can improve engagement and understanding of molecular biology topics, and so we developed a graphical educational resource, the SARS-CoV-2 Spike Protein Mutation Explorer (SSPME), which used interactive 3D molecular models and animations to explain the molecular biology underpinning VOCs. User testing showed that the SSPME had better usability and improved participant knowledge confidence and knowledge acquisition compared to COG-UK/ME. This demonstrates how interactive visualisations can be used for effective molecular biology communication, as well as improving the public understanding of SARS-CoV-2 VOCs.

description: We analyze the cosmic-ray signatures of decaying gravitino dark matter in a model independent way based on an operator analysis. Thermal leptogenesis and universal boundary conditions at the GUT scale restrict the gravitino mass to be below 600 GeV. Electron and positron fluxes from gravitino decays, together with the standard GALPROP background, cannot explain both, the PAMELA positron fraction and the electron + positron flux recently measured by Fermi LAT. For gravitino dark matter, the observed fluxes require astrophysical sources. The measured antiproton flux allows for a sizable contribution of decaying gravitinos to the gamma-ray spectrum, in particular a line at an energy below 300 GeV. Future measurements of the gamma-ray flux will provide important constraints on possible signatures of decaying gravitino dark matter at the LHC.

description: Off-Policy Prediction (OPP), i.e., predicting the outcomes of a target policy using only data collected under a nominal (behavioural) policy, is a paramount problem in data-driven analysis of safety-critical systems where the deployment of a new policy may be unsafe. To achieve dependable off-policy predictions, recent work on Conformal Off-Policy Prediction (COPP) leverage the conformal prediction framework to derive prediction regions with probabilistic guarantees under the target process. Existing COPP methods can account for the distribution shifts induced by policy switching, but are limited to single-agent systems and scalar outcomes (e.g., rewards). In this work, we introduce MA-COPP, the first conformal prediction method to solve OPP problems involving multi-agent systems, deriving joint prediction regions for all agents' trajectories when one or more ego agents change their policies. Unlike the single-agent scenario, this setting introduces higher complexity as the distribution shifts affect predictions for all agents, not just the ego agents, and the prediction task involves full multi-dimensional trajectories, not just reward values. A key contribution of MA-COPP is to avoid enumeration or exhaustive search of the output space of agent trajectories, which is instead required by existing COPP methods to construct the prediction region. We achieve this by showing that an over-approximation of the true joint prediction region (JPR) can be constructed, without enumeration, from the maximum density ratio of the JPR trajectories. We evaluate the effectiveness of MA-COPP in multi-agent systems from the PettingZoo library and the F1TENTH autonomous racing environment, achieving nominal coverage in higher dimensions and various shift settings.

description: Aims. We gathered about 100 high-resolution spectra of three typical HgMn (mercury-manganese) stars, HD 11753, HD 53244, and HD 221507, to search for slowly pulsating B-like pulsations and surface inhomogeneous distribution of various chemical elements. Methods. Classical frequency analysis methods were used to detect line profile variability and to determine the variation period. Doppler imaging reconstruction was performed to obtain abundance maps of chemical elements on the stellar surface. Results. For HD 11753, which is the star with the most pronounced variability, distinct spectral line profile changes were detected for Ti, Sr, Y, Zr, and Hg, whereas for HD 53244 and HD 221507 the most variable line profiles belong to the elements Hg and Y, respectively. We derived rotation periods for all three stars from the variations of radial velocities and equivalent widths of spectral lines belonging to inhomogeneously distributed elements: P_rot (HD 11753)=9.54 d, P_rot (HD 53244)=6.16 d, and P_rot (HD 221507)=1.93 d. For HD 11753 the Doppler imaging technique was applied to derive the distribution of the most variable elements Ti, Sr, and Y using two datasets separated by ~65 days. Results of Doppler imaging reconstruction revealed noticeable changes in the surface distributions of TiII, SrII, and YII between the datasets, indicating the hitherto not well understood physical processes in stars with radiative envelopes that cause a rather fast dynamical chemical spot evolution.
