description: In order to detect patterns in real networks, randomized graph ensembles that preserve only part of the topology of an observed network are systematically used as fundamental null models. However, their generation is still problematic. The existing approaches are either computationally demanding and beyond analytic control, or analytically accessible but highly approximate. Here we propose a solution to this long-standing problem by introducing an exact and fast method that allows to obtain expectation values and standard deviations of any topological property analytically, for any binary, weighted, directed or undirected network. Remarkably, the time required to obtain the expectation value of any property is as short as that required to compute the same property on the single original network. Our method reveals that the null behavior of various correlation properties is different from what previously believed, and highly sensitive to the particular network considered. Moreover, our approach shows that important structural properties (such as the modularity used in community detection problems) are currently based on incorrect expressions, and provides the exact quantities that should replace them.

Improvement of nuclear decommissioning and dismantling planning via experience ex-change and optimisation methods

description: Worldwide lots of nuclear power reactors will be shut down and dismantled in the next years. Apart from the technical aspects of decommissioning and dismantling (D&D), the economic view is important. Therefore, project management and especially the planning of D&D are in the centre of attention. Because of the long range project of dismantling nuclear facilities, with high requirements for safety and security, an expected makespan of about 15 to 20 years and a budget with about 0.5 to 1 billion Euros per facility the planning is very challenging. Furthermore, there is very little experience in D&D project planning and execution worldwide. 
To meet these challenges, on the one hand experience exchange is needed to get best practices, which is essential to plan and perform D&D safely and cost-minimally. An international approach of cooperation in the optimization process of D&D could be beneficial. On the other hand, efficient planning tools are needed to generate a robust project plan under uncertainty. Therefore, we developed a decision making model that provides a calculation of a robust dismantling plan with minimal total project costs. The algorithms used combine existent experience in D&D and optimization-methods for scheduling under uncertainty.
Arabidopsis MKK6 functions in parallel with MKK1 and MKK2 to negatively regulate plant immunity
Creators: name: Gao, Fang
Publisher: name: University of British Columbia
Year: 2018

description: As an early defense response, MAP kinase cascade activation plays important roles in transduction and amplification of signals upon pathogen perception in plants. The Arabidopsis MEKK1-MKK1/MKK2-MPK4 kinase cascade was previously shown to negatively regulate plant immunity. In this study, two suppressors of the mkk1 mkk2 double mutant – summ4-1D and summ4-2D have been identified and characterized. summ4-1D and summ4-2D contain mutations in the promoter region of MKK6, which leads to elevated expression of MKK6, causing suppression of the mkk1 mkk2 autoimmune phenotypes. However, the autoimmune phenotypes of mekk1 and mpk4 cannot be suppressed by summ4-1D. MKK6 interacts with MEKK1 and MPK4, and MPK4 activation is blocked in mkk1 mkk2, but is recovered in the summ4-1D mkk1 mkk2 triple mutant background. These results suggest that MKK6 functions in parallel with MKK1 and MKK2 to negatively regulate plant immunity.

description: We use quantum diffusive trajectories to prove that the time evolution of two-qubit entanglement under spontaneous emission can be fully characterized by optimal continuous monitoring. We analytically determine this optimal unraveling and derive a deterministic evolution equation for the system's concurrence. Furthermore, we propose an experiment to monitor the entanglement dynamics in bipartite two-level systems and to determine the disentanglement time from a single trajectory.

description: After recalling the concept of the Hausdorff dimension, we study the fractal properties of a quantum particle path. As a novelty we consider the possibility for the space where the particle propagates to be endowed with a quantum-gravity-induced minimal length. We show that the Hausdorff dimension accounts for both the quantum mechanics uncertainty and manifold fluctuations. In addition the presence of a minimal length breaks the self-similarity property of the erratic path of the quantum particle. Finally we establish a universal property of the Hausdorff dimension as well as the spectral dimension: They both depend on the amount of resolution loss which affects both the path and the manifold when quantum gravity fluctuations occur.

description: We study a two-dimensional electron system in the presence of spin-orbit interaction. It is shown analytically that the spin-orbit interaction acts as a transversal effective electric field, whose orientation depends on the sign of the $\hat{z}$-axis spin projection. This effect doesn't require any driving external field and is inherent to the spin-orbit interactions present in semiconductor materials. Therefore, it should manifest in both closed and open systems. It is proposed an experiment to observe the intrinsic spin Hall effect in the far infrared absorption of an asymmetric semiconductor nanostructure.

Research funding

description: This brief explores some of the drivers of precarity that are inherently built-in to our current contestable research funding model; although not by design. Herein, it is also highlighted why funding research and indeed researchers, 100% from contestable sources, does not reflect the reality of what academic researchers do with their time. In reality, researchers need to use a % of their time to do research-related (research-support) tasks, career-building tasks as well as research community contributions that are not explicitly described within the research projects that actually supply 100% of their salary. The system also fails to recognise that research is a continuum of knowledge-building rather than a series of individual research projects. With no element of stable funding base in the current system, the ability of researchers to carry out knowledge-building is compromised and there is therefore knowledge-loss. Precarity of our research workforce also drives skill-loss and is subsequently wasting money and resources. The proposal of a base grant model goes some way to recognise the reality of how research is actually carried out and therefore support a more efficient, flexible system, putting people and their talent first.

Vitamin B-12 status during pregnancy and infancy : screening tools and assessment of populations at risk for deficiency
Creators: name: Schroder, Theresa H.
Publisher: name: University of British Columbia
Year: 2020

description: Low perinatal and infantile vitamin B-12 (B-12) status have been associated with health complications. South Asians and residents of low- and middle-income countries may be at increased risk for low B-12 status. The overall goal was to facilitate and screen for perinatal, neonatal, and infantile B-12 status. First, a reliable (recovery: 93–98%; CV: <7%) tool for B-12 status assessment in vulnerable populations was developed, using dried blood spot methylmalonic acid (DBS MMA) concentrations. MMA is the most specific functional B-12 biomarker. Given the minimal invasiveness and ease of DBS collection, DBS MMA may be convenient to use in newborns and populations in remote settings to estimate B-12 status. As such, a reference value of elevated neonatal DBS MMA concentration of >29.3 pmol/8-mm punch was computed per clinical guidelines (CLSI EP18-A3c). Further, B-12 status of South Asian and European pregnant women and their newborns living in Vancouver were compared. B-12 status was assessed in 748 healthy Vancouver women (50% South Asian, 50% European) during their 1st and 2nd trimester of pregnancy using multiple B-12 biomarkers, and in their newborns using DBS MMA concentration. South Asian pregnant women had a significantly lower B-12 status than European women, e.g. comparing 1st trimester mean (95% CI) serum total B-12 concentrations [189 (180; 199) pmol/L versus 246 (236; 257) pmol/L; P<0.0001]. This difference in B-12 status was not reflected in the DBS MMA concentrations of their newborns. Last, the prevalence of B-12 deficiency in mothers and their infants living in rural Indonesia was determined. The prevalence of infants (n=221) living in rural Indonesia with serum total B-12 concentrations <191pmol/L followed at age 6-, 9-, and 12-months was 27%. Maternal DBS MMA concentrations at 6 months postpartum were weakly, but statistically significantly (P=0.004), associated with infant serum MMA concentrations. This research suggests DBS MMA is a convenient screening tool with use in vulnerable populations, including newborns. Pregnant South Asian women living in Vancouver and infants living in rural Indonesia were identified as populations at risk for low B-12 status. Future research evaluating outcomes and predictors of low B-12 status is warranted allowing for targeted interventions.

description: We investigate the properties of the Heisenberg S=1 chain with bilinear and biquadratic interactions in a magnetic field using the Density Matrix Renormalization Group, Bethe ansatz and field theoretical considerations. In a large region of the parameter space, we identify a magnetized ferroquadrupolar Luttinger liquid consisting of a quasi-condensate of bound magnon pairs. This liquid undergoes a continuous pair unbinding transition to a more conventional Luttinger liquid region obtained by polarizing the system above the Haldane gap region. This pair unbinding transition is shown to be in the Ising universality class on top of a Luttinger liquid, leading to an effective central charge 3/2. We also revisit the nature of the partially polarized Luttinger liquid around and above the Uimin-Lai-Sutherland point. Our results confirm that this is a two-component liquid and rule out the formation of a single-component vector chiral phase.

Characterizing the neural correlates of children with developmental coordination disorder using diffusion tensor imaging
Creators: name: Brown-Lum, Meisan
Publisher: name: University of British Columbia
Year: 2018

description: Developmental coordination disorder (DCD) is a neurodevelopmental disorder of unknown etiology characterized by poor motor coordination and difficulty learning motor skills. Recent research has shown brain differences in children with DCD compared to typically-developing children. Diffusion Tensor Imaging (DTI) is a neuroimaging technique used to identify diffusion properties of white matter of the brain. Only a handful of studies have started to elucidate the white matter pathways that are implicated in children with DCD. These studies used tractography to look at a priori white matter pathways. The objective of this thesis is to be the first to apply a DTI method called tract-based spatial statistics (TBSS), a user independent analysis of the whole brain white matter to investigate the neural correlates of children with and without DCD. We hypothesized that the white matter differences would be widespread and implicate white matter pathways such as the: corticospinal motor tract (CST); sensorimotor pathways of the posterior thalamic radiation (PTR); corpus callosum; and cerebellar pathways (CP). To achieve our research goals, DTI data were collected from 61 children between 8-12 years of age (31 DCD; 30 TD) who had an MRI scan at a mean age of 10.02 years. Voxel-wise statistical analysis of diffusion metrics such as fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) was conducted using TBSS. A two-group comparison design matrix with age and attention as covariates was used. Data were corrected for multiple comparisons across space and statistical significance was set at p<0.05. Lastly, we investigated whether there was a relationship between the diffusion metrics and motor performance using Spearman’s correlation coefficient. Our findings suggest that children with DCD show altered, widespread diffusion parameters of white matter in pathways associated with the CST, PTR and CP. Of clinical significance, FA and AD positively correlated with motor performance. Findings from this study will contribute to the scarcity of existing data on characterizing neural correlates of DCD. This research will help elucidate the pathophysiology of DCD and, also, inform intervention studies to investigate motor learning that will, ultimately, help optimize motor functioning in children with DCD.

description: We extend the concept of entanglement spectrum from the geometrical to the particle bipartite partition. We apply this to several Fractional Quantum Hall (FQH) wavefunctions on both sphere and torus geometries to show that this new type of entanglement spectra completely reveals the physics of bulk quasihole excitations. While this is easily understood when a local Hamiltonian for the model state exists, we show that the quasiholes wavefunctions are encoded within the model state even when such a Hamiltonian is not known. As a nontrivial example, we look at Jain's composite fermion states and obtain their quasiholes directly from the model state wavefunction. We reach similar conclusions for wavefunctions described by Jack polynomials.

Can the LHC rule out the MSSM ?

description: If supersymmetry (SUSY) exists in nature and is a solution to the hierarchy problem then it should be detectable at the TeV energy scale which the large hadron collider (LHC) is now exploring. One of the main goals of the LHC is the discovery or exclusion of the R-parity conserving minimal supersymmetric standard model (MSSM). So far, the SUSY search results are presented in the context of the constrained MSSM and other specific simplified SUSY models. A model-independent analysis necessarily relies on the trigger-system of the LHC detectors. By using the posterior samples of a 20-parameter MSSM, the phenomenological MSSM, from a fit to indirect collider and cosmological data we find that there is a significant volume in the MSSM parameter space that would escape the standard trigger-systems of the detectors. As such, in the absence of discovery in the current and future LHC runs, it would be difficult if not impossible to exclude the MSSM unless some dedicated and special triggers are commissioned or a Higgs boson with mass as predicted by the supersymmetric models is not found.

The A.B.C Approach for Cancer Treatment
Creators: name: forrest, Russell
Publisher: name: Zenodo
Year: 2024

description: Abstract

 

The A.B.C. approach represents a novel, multi-step cancer treatment methodology focused on systematically breaking down cancer cell defenses, preventing metastasis, and eliminating cancerous cells. Comprised of three distinct phases—Attack, Block, and Conquer—this approach integrates advanced biotechnology, bioengineered bacteria, and real-time AI-driven monitoring to deliver a highly precise and targeted therapy. Each phase of the approach addresses the unique challenges presented by the tumor microenvironment and cancer's ability to evade the immune system. This paper details the theory, methodology, and future clinical implications of the A.B.C. approach, highlighting its potential to offer a more efficient and safer cancer treatment strategy.

description: We report a direct observation of Ge hut nucleation on Si(001) during UHV MBE. The study was carried out using a UHV instrument coupling MBE chamber and STM which enables the sample study on atomic level at any stage of treatment. Si wafers were deoxidized by annealing at 925C. Ge was deposited by electron beam evaporation; the coverage was varied from 3 to 14 Å; the wafer temperature was 360C. The nuclei of pyramids and wedges were observed on the (MxN) wetting layer (WL) patches and found to have different structures. The atomic models of nuclei of both hut species have been built as well as the models of the growing clusters. The growth of huts of each species has been demonstrated to follow generic scenarios. The formation of the second atomic layer of the wedge results in rearrangement of its first layer. Its ridge structure does not repeat the nucleus. The pyramid grows without phase transitions. The structure of its vertex copies the nucleus. Transitions between hut species are impossible. The wedges contain point defects in the upper corners of the triangular faces and have preferential growth directions along the ridges. The derived structure of the {105} facet turned out to follow the PD model. Further growth of hut arrays results in domination of wedges, the density of pyramids exponentially drops. The heights of wedges are limited; no limitation of pyramid heights is observed. The second generation of huts arises at coverages >10 Å; new huts occupy the whole WL.

description: Chameleons are scalar fields that couple directly to ordinary matter with gravitational strength, but which nevertheless evade the stringent constraints on tests of gravity because of properties they acquire in the presence of high ambient matter density. Chameleon theories were originally constructed in a bottom-up, phenomenological fashion, with potentials and matter couplings designed to hide the scalar from experiments. In this paper, we attempt to embed the chameleon scenario within string compactifications, thus UV completing the scenario. We look for stabilized potentials that can realize a screening mechanism, and we find that the volume modulus rather generically works as a chameleon, and in fact the supersymmetric potential used by Kachru, Kallosh, Linde and Trivedi (KKLT) is an example of this type. We consider all constraints from tests of gravity, allowing us to put experimental constraints on the KKLT parameters.

description: We present the theory of the inplane magnetoresistance in two-dimensional massless Dirac fermion systems including the Zeeman splitting and the electron-electron interaction effect on the Landau level broadening within a random phase approximation. With the decrease in temperature, we find a characteristic temperature dependence of the inplane magnetoresistance showing a minimum followed by an enhancement with a plateau. The theory is in good agreement with the experiment of the layered organic conductor α-(BEDT-TTF)_2I_3 under pressure. In-plane magnetoresistsnce of graphene is also discussed based on this theory.

VLCFAs are elongated by a fatty acid elongation (FAE) complex of four core enzymes located on the endoplasmic reticulum, which sequentially adds two carbon units to a growing acyl-CoA chain. Identification and characterization of FAE enzymes in Arabidopsis thaliana has revealed that three of the four enzymes act as generalists, contributing to all metabolic pathways that require VLCFAs. A fourth component, the condensing enzyme, provides substrate specificity and determines the chain length of product synthesized by the entire complex. Chain length is important because it defines what downstream pathway a VLCFA can be used for. In Arabidopsis, characterized condensing enzymes can only elongate VLCFAs up to 28 carbons in length, despite the predominance of 29- and 31-carbon components in plant cuticular wax. This suggests that elongation beyond 28 carbons is unique and requires different protein components. The wax-deficient mutant eceriferum2 (cer2) of Arabidopsis lacks waxes longer than 28 carbons, suggesting that CER2 is specifically required for VLCFA extension past this threshold length. Molecular characterization of the CER2 gene, both in planta and by heterologous expression in Saccharomyces cerevisiae, demonstrates that CER2 is a component of the elongation machinery required to synthesize 30-carbon cuticular wax precursors (Chapter 3). Five homologous CER2-LIKE genes were identified in Arabidopsis; these CER2-LIKEs have similar metabolic functions to CER2, but different expression patterns and substrate specificities (Chapter 4). CER2-LIKEs form a distinct clade of the BAHD acyltransferase superfamily. However, structural predictions and site-directed mutagenesis reveal fundamental differences in the mechanism of activity of CER2-LIKEs relative to characterized BAHDs (Chapter 5). My results suggest that CER2-LIKEs enable condensing enzymes to accept longer VLCFA substrates. I suggest several mechanisms to explain the activity of CER2-LIKEs. This peculiarity of elongation is unique to land plants, and to the production of cuticular wax precursors. Because the acquisition of cuticles as barriers to transpirational water loss was key to plant colonization of land, CER2-LIKE activity is an important specialization of plant lipid metabolism.

description: To ensure compliance with stricter regulations on exhaust gas emissions, new industrial burner concepts are being investigated. One of these concepts is the matrix burner, consisting of an array of premixed, non-swirling jet flames. For the design of such burners, the prediction of fundamental burner properties is mandatory. One of these essential quantities is the lean blowout limit (LBO), which has already been investigated experimentally. This study investigates the possibility of numerical LBO prediction using a tabulated chemistry approach in combination with Large-Eddy-Simulation turbulence modeling. In contrast to conventional swirl burners, the numerical description of blowout events of multi jet flames has not yet been studied in detail. Lean blowout simulations have therefore been conducted for multiple nozzle variants, varying in their diameter and global dump ratio for a variety of operating conditions, showing their general applicability. A procedure to induce LBO is introduced where a stepwise increase in total mass flow is applied. LBO is determined based on the temporal progress of the mean reaction rate. A comparison with measurements shows good agreement and demonstrates that the procedure developed here is an efficient way to predict LBO values. Further investigations focused on the flame behavior when approaching LBO. The flame shape shows a drastic change from single jet flames (stable conditions) to a joint conical flame approaching LBO, which increases in length for increasing inlet velocity, showing the importance of jet interaction at LBO.

description: We mode Solar coronal mass ejections (CMEs) as expanding force-fee magnetic structures and find the self-similar dynamics of configurations with spatially constant α, where {\bf J} =α{\bf B}, in spherical and cylindrical geometries, expanding spheromaks and expanding Lundquist fields correspondingly. The field structures remain force-free, under the conventional non-relativistic assumption that the dynamical effects of the inductive electric fields can be neglected. While keeping the internal magnetic field structure of the stationary solutions, expansion leads to complicated internal velocities and rotation, induced by inductive electric field. The structures depends only on overall radius R(t) and rate of expansion \dot{R}(t) measured at a given moment, and thus are applicable to arbitrary expansion laws. In case of cylindrical Lundquist fields, the flux conservation requires that both axial and radial expansion proceed with equal rates. In accordance with observations, the model predicts that the maximum magnetic field is reached before the spacecraft reaches the geometric center of a CME.

description: As energetic, health and environmental requirements for buildings are changing, deconstruction of buildings in the course of retrofits or replacing construction is increasingly important. To plan change measures in existing buildings, buildings have to be audited manually which is associated with great effort. In our contribution, we propose and describe a combined system of a hardware sensor with software modules for building information acquisition, reconstruction and project planning. Furthermore, technical requirements, the acquired data, user interaction and system architecture are discussed. Our tool enables planner, experts or decision makers to inspect a building and at the same time digitally audit the building room by room. For this purpose, point clouds are acquired, analysed and a 3D building model is automatically derived to record it. Furthermore, the acquired data is automatically analysed in realtime to detect construction elements that are saved in a database. Then, based on the generated building element database building reconstruction and planning algorithms use the information for building inventorying and project planning. This allows integrated planning of decontamination, site clearance, and deconstruction activities, as well as to coordinate secondary raw material recovery, resources, logistics, material storage and recycling options time and cost efficiently onsite. Results from first field tests on acquisition, reconstruction and deconstruction planning are presented and discussed. Finally, a summary and a conclusion are given. This is followed by an outlook on potential future research and application areas.

description: In order to test the possible interaction between dark energy and dark matter, we investigate observational constraints on a phenomenological scenario, in which the ratio between the dark energy and matter densities is proportional to the power law case of the scale factor, $r\equiv (ρ_X/ρ_m)\propto a^ξ$. By using the Markov chain Monte Carlo method, we constrain the phenomenological interacting dark energy model with the newly revised $H(z)$ data, as well as the cosmic microwave background (CMB) observation from the 7-year Wilkinson Microwave Anisotropy Probe (WMAP7) results, the baryonic acoustic oscillation (BAO) observation from the spectroscopic Sloan Digital Sky Survey (SDSS) data release 7 (DR7) galaxy sample and the type Ia supernovae (SNe Ia) from Union2 set. The best-fit values of the model parameters are $Ω_{m0}=0.27_{-0.02}^{+0.02}(1σ)_{-0.03}^{+0.04}(2σ)$, $ξ=3.15_{-0.50}^{+0.48}(1σ)_{-0.71}^{+0.72}(2σ)$, and $w_X=-1.05_{-0.14}^{+0.15}(1σ)_{-0.21}^{+0.21}(2σ)$, which are more stringent than previous results. These results show that the standard $Λ$CDM model without any interaction remains a good fit to the recent observational data; however, the interaction that the energy transferring from dark matter to dark energy is slightly favored over the interaction from dark energy to dark matter. It is also shown that the $H(z)$ data can give more stringent constraints on the phenomenological interacting scenario when combined to CMB and BAO observations, and the confidence regions of $H(z)$+BAO+CMB, SNe+BAO+CMB, and $H(z)$+SNe+BAO+CMB combinations are consistent with each other.

description: We consider dipolar interactions between heteronuclear molecules in a low-dimensional setup consisting of two one-dimensional tubes. We demonstrate that attraction between molecules in different tubes can overcome intratube repulsion and complexes with several molecules in the same tube are stable. In situ detection schemes of the few-body complexes are proposed. We discuss extensions to the case of many tubes and layers, and outline the implications of our results on many-body physics.

Mechanisms of acute leukemia disease initiation and maintenance through manipulation of IGF1R and RUNX family members.

description: Characterization of new pathways in Acute Myeloid Leukemia and T-cell Acute Lymphoblastic Leukemia which contribute to oncogenesis is necessary to relieve dependence on conventional chemotherapy for treatment of these diseases. In this dissertation, I characterized the role of signaling molecules (IGF1R) and transcription factors (RUNX1, RUNX3, NOTCH1) in regulating mechanisms of leukemia initiation and maintenance. I discovered that committed myeloid progenitor cells with genetically reduced levels of IGF1R were less susceptible to myelogenous leukemogenic transformation due, at least in part, to a cell-autonomous defect in clonogenic activity. Genetic deletion of IGF1R by inducible Cre recombinase however had no effect on growth/survival of established leukemia cells. I raise the possibility that IGF1R inhibitors in clinical development may be acting through alternate/related pathways. Second, in a retroviral insertional mutagenesis study, I cloned retroviral integration sites from hNOTCH1ΔE mouse leukemias to find genes which collaborate with Notch signaling in T-ALL initiation. Common integration sites include the previously identified Ikzf1, and a novel potentially Notch-collaborating gene, Runx3. Using a multicistronic lentiviral system, I show that RUNX1A, RUNX1B and RUNX3 were able to collaborate with the ΔEΔL allele of NOTCH1 to initiate leukemia. Finally, I sought to understand how RUNX1 and RUNX3 contribute to the biology of established T-cell leukemias. I found that both RUNX1 and RUNX3 contribute to T-ALL cell proliferation and survival. Although RUNX3 can induce cell proliferation, RUNX1 expression is finely tuned with overexpression and knockdown resulting in negative growth phenotypes. This may be in part to regulation of MYC, IL7R, IGF1R, and CDKN1B as well as affecting genome-wide H3K27Ac. I found that RUNX1 expression was targeted by the CDK7 inhibitor, THZ1. RUNX1 and RUNX3 are mediators of Notch-directed regulation of PKCθ, and as such are indirect regulators of LIC-activity. Finally, I showed that RUNX1 and Notch signaling provide complimentary, additive signals for growth of T-ALL cells. These experiments provide insight into the role of RUNX1 mutations in T-cell leukemia and point to a complementary role in supporting the Notch pathway.
