description: It is well-known that e$^+$e$^-$ colliders have the power to with certainty exclude or discover any SUSY model that predicts a Next to lightest SUSY particle (an NLSP) that has a mass up to slightly below the half the centre-of-mass energy of the collider. Here, we present an estimation of the power of present and future hadron colliders to extend the reach of searches for SUSY, with particular emphasis whether it can be claimed that either discovery or exclusion is guaranteed in a region of LSP and NLSP masses - no set of values of the other SUSY could change the conclusion. A scan over SUSY parameter space was done, only requiring that the NLSP was a bosino - the hardest case - with mass not larger than a few TeV. The mass-spectrum, cross-sections and decay branching ratios found in this region were confronted with projections of sensitivity at future hadron colliders. In our conclusions we weigh in the maturity of the analysis the projections are based upon. The conclusion is that although future hadron colliders have a large discovery-reach, i.e. potential to discover some SUSY model, hardly any models with low-to-medium LSP-NLSP mass-differences can be excluded with certainty. The models that are expected to be excluded/discovered are, on one hand, those with mass-differences larger than those allowed by models with GUT-scale $M_1$-$M_2$ unification, and on the other hand, a tiny region where the mass-difference is so small that the NLSP decays in the tracking volume of the detectors. Excluding the latter possibility does not, however, allow to exclude the possibility of a Wino or Higgsino LSP: at any value of the LSP mass, we could identify models where the NLSP lifetime would be too short for a signal to be seen.
The FDF or LES/PDF method for turbulent two-phase flows

description: In this paper, a new formalism for the filtered density function (FDF) approach is developed for the treatment of turbulent polydispersed two-phase flows in LES simulations. Contrary to the FDF used for turbulent reactive single-phase flows, the present formalislm is based on Lagrangian quantities and, in particular, on the Lagrangian filtered mass density function (LFMDF) as the central concept. This framework allows modeling and simulation of particle flows for LES to be set in a rigorous context and various links with other approaches to be made. In particular, the relation between LES for particle simulations of single-phase flows and Smoothed Particle Hydrodynamics (SPH) is put forward. Then, the discussion and derivation of possible subgrid stochastic models used for Lagrangian models in two-phase flows can set in a clear probabilistic equivalence with the corresponding LFMDF.

Assessing gaps and variations in depression care and the impact of physician incentives

Publisher: name: University of British Columbia

description: Depression is increasingly becoming the leading cause of disability worldwide. While effective treatments like psychological or antidepressant therapies are available, concerns remain about under treatment and disparities in care as these can adversely affect mental health outcomes. Through a series of studies, this thesis estimated the magnitude of the gap and variations in depression care and the impact physician incentives had on treatment gaps. To perform all population-based analyses, this thesis used linked health administrative data from the Canadian province of British Columbia. An algorithm for identifying cohorts was developed to ensure that observation periods for detecting diagnosis and assessing use of mental health care were identical for all individuals. Administrative data were used to derive indicators that measure receipt of counseling/psychotherapy, receipt of antidepressants, adherence to antidepressant therapy, and physician continuity of care. Analytical approaches used in the study include calculating proportions to estimate treatment gaps, building generalized and mixed effects regression models to examine treatment variations and running interrupted time series analysis to investigate policy impacts. Results of the analyses suggest that four out of ten individuals with depression did not receive any depression care from the formal health system. Among the treated, only one in two received minimally adequate care, mostly through antidepressants. Minimally adequate treatment varied by sex, age, overall health status, place of residence, physician practice, and presence of specific comorbid physical conditions. Study results also indicate that physician incentives affected depression care patterns, although the overall impact was modest. Specifically, the downward trend in counseling/psychotherapy and the upward trend in antidepressant therapy initiation were disrupted. Likewise, the percentage of individuals who received minimally adequate counseling/psychotherapy increased gradually over time while the percentage of those who received minimally adequate antidepressant therapy decreased. Some gains were also achieved in measures of physician continuity of care. Overall, study results show that wide gaps in depression care persist despite recent efforts to improve mental health care. Expanding public coverage for psychological therapies and exploring reforms that require fundamental changes in mental health service delivery are needed to enhance treatment options and accessibility.

description: Structure function of e+e- to hadrons cross section proportional to the longitudinal part of the hadron tensor is power suppressed with respect to an event shape variable in the two-jet region. In the SCET framework, we study the event shape distribution for this structure function to NLL level of accuracy. As, a result we obtain the angular distribution of hadron jets as a function of the thrust, in the two jet region. We further examine effects of non-perturbative hadronization corrections by adopting a shape function that reproduce the observed event shape distributions. Impacts of our findings on the electroweak measurements via the jet angular forward-backward asymmetry are discussed.

description: We present a time-saving simulator within the framework of the density functional theory to calculate the transport properties of electrons through nanostructures suspended between semi-infinite electrodes. By introducing the Fourier transform and preconditioning conjugate-gradient algorithms into the simulator, a highly efficient performance can be achieved in determining scattering wave functions and electron-transport properties of nanostructures suspended between semi-infinite jellium electrodes. To demonstrate the performance of the present algorithms, we study the conductance of metallic nanowires and the origin of the oscillatory behavior in the conductance of an Ir nanowire. It is confirmed that the $s$-$d_{z^2}$ channel of the Ir nanowire exhibits the transmission oscillation with a period of two-atom length, which is also dominant in the experimentally obtained conductance trace.

description: Focal adipose deficiency, such as lipoatrophy, lumpectomy or facial trauma, is a formidable challenge in reconstructive medicine, and yet scarcely investigated in experimental studies. Here, we report that Pyrintegrin (Ptn), a 2,4-disubstituted pyrimidine known to promote embryonic stem cells survival, is robustly adipogenic and induces postnatal adipose tissue formation in vivo of transplanted adipose stem/progenitor cells (ASCs) and recruited endogenous cells. In vitro, Ptn stimulated human adipose tissue derived ASCs to differentiate into lipid-laden adipocytes by upregulating peroxisome proliferator-activated receptor (PPARγ) and CCAAT/enhancer-binding protein-α (C/EBPα), with differentiated cells increasingly secreting adiponectin, leptin, glycerol and total triglycerides. Ptn-primed human ASCs seeded in 3D-bioprinted biomaterial scaffolds yielded newly formed adipose tissue that expressed human PPARγ, when transplanted into the dorsum of athymic mice. Remarkably, Ptn-adsorbed 3D scaffolds implanted in the inguinal fat pad had enhanced adipose tissue formation, suggesting Ptn’s ability to induce in situ adipogenesis of endogenous cells. Ptn promoted adipogenesis by upregulating PPARγ and C/EBPα not only in adipogenesis induction medium, but also in chemically defined medium specifically for osteogenesis, and concurrently attenuated Runx2 and Osx via BMP-mediated SMAD1/5 phosphorylation. These findings suggest Ptn’s novel role as an adipogenesis inducer with a therapeutic potential in soft tissue reconstruction and augmentation.

description: Voltage sensitivity expresses analytically the dependency between voltage and active or reactive power. Knowing the voltage sensitivity is necessary in many power system applications, such as the Distributed Energy Resources (DER) optimal placement and control. The majority of voltage sensitivity estimation methods assume having an accurate model of the grid and only consider a balanced grid operation at the nominal point, which is not realistic. In this paper, a method based on Mutual Information (MI) is proposed, which is able to evaluate the nonlinear dependencies between two variables, in order to estimate the relative voltage sensitivity. Contrary to the existing methods, the proposed MI-based approach only requires measurements at the point of interest and does not require any grid model nor measurements from other nodes in the grid. As a use case, the optimal allocation for an Energy Storage System (ESS) in a real medium voltage network in Germany has been presented. Measurement results confirm the effectiveness of the new approach for estimating relative voltage sensitivity.
Determining the Magnetization of the Quiet Sun Photosphere from the Hanle Effect and Surface Dynamo Simulations

description: The bulk of the quiet solar photosphere is thought to be significantly magnetized, due to the ubiquitous presence of a tangled magnetic field at subresolution scales with an average strength  ~ 100 G. This conclusion was reached through detailed three-dimensional (3D) radiative transfer modeling of the Hanle effect in the Sr I 4607 line, using the microturbulent field approximation and assuming that the shape of the probability density function of the magnetic field strength is exponential. Here we relax both approximations by modeling the observed scattering polarization in terms of the Hanle effect produced by the magnetic field of a 3D photospheric model resulting from a (state-of-the-art) magneto-convection simulation with surface dynamo action. We show that the scattering polarization amplitudes observed in the Sr I 4607 line can be explained only after enhancing the magnetic strength of the photospheric model by a sizable scaling factor, F=10, which implies  = 130 G in the upper photosphere. We argue also that in order to explain both the Hanle depolarization of the Sr I 4607 line and the Zeeman signals observed in Fe I lines we need to introduce a height-dependent scaling factor, such that the ensuing  = 160 G in the low photosphere and  = 130 G in the upper photosphere.

A reverse curse of knowledge in childhood
Creators: name: Ghrear, Siba
Publisher: name: University of British Columbia
Year: 2020

description: Communicating effectively involves reasoning about what others know. Yet ample research shows that our ability to reason about what others’ know is sometimes compromised by the ‘curse of knowledge’: a tendency to be biased by one’s current knowledge when reasoning about a more naïve perspective. To date no research has examined this bias in children’s estimates of how widely known information is among their peers. My thesis fills that gap. One hundred and twenty 4 to 7-year-olds were presented with eight factual questions and asked to judge how common that knowledge is among their peers. Children were taught the answers to only half of the questions. I predicted that: 1. Children would estimate that more of their peers would know the answers to the facts they were taught versus not taught, 2. The bias would decrease with age, and 3. The magnitude of children’s bias in their peer judgements would correlate with the magnitude of their bias in judging another individual’s visual perspective. Contrary to my predictions, children estimated that less of their peers would know the answers to the taught versus not taught questions. Children’s ‘reverse curse of knowledge’ did not vary by age and did not correlate with their judgement of another individual’s visual perspective. Nonetheless, these results shed light on the nature of the mechanisms underlying the curse of knowledge and make important contributions to our understanding of how children reason about what others know.

The change by jump of measured parameters because of the macroscopic discreteness may be used for some applications. A device is proposed measured parameters of which can change by jump at a weak change of external parameters. The devise consists of two superconductor loop connected with two Josephson junctions. The macroscopic parameter - maximum value of the super-current through the two Josephson junctions - can change with the quantum number determining macroscopic angular momentum of superconducting pairs in one of the two loops.

description: We consider the scattering of fermions off antifermions with spin 1/2 and 3/2. Starting from helicity partial-wave scattering amplitudes we derive transformations that eliminate all kinematical constraints. Such amplitudes are expected to satisfy partial-wave dispersion relations and therefore provide a suitable basis for data analysis and the construction of effective field theories. Our derivation relies on a decomposition of the various scattering amplitudes into suitable sets of invariant functions.

description: Poster presented during the 42nd CIESM Conference in Cascais in October 2019 (http://ciesm.org/marine/congresses/Cascais.htm) Abstract: In the past, the Mediterranean has been sampled sporadically in time and space, mostly by national expeditions in regional waters. An outcome of a CIESM Workshop (2012) was a recommendation for repeated oceanographic surveys of the Mediterranean in a programme called Med-SHIP, to observe the changing circulation in a manner similar to the international GOSHIP programme for the global ocean. Mediterranean marine scientists have designed a network of hydrographic sections on which comprehensive physical and biogeochemical properties will be measured to highest international standards on a regular basis. In 2016 the first cycle of repeat surveys along the Med-SHIP network has been completed. Here the physics and biogeochemistry of the two meridional transects in the Western Mediterranean Sea are shown and discussed.

description: It is a fundamental problem in geometry to decide which moduli spaces of polarized algebraic varieties are embedded by their period maps as Zariski open subsets of locally Hermitian symmetric domains. In the present work we prove that the moduli space of Calabi-Yau threefolds coming from eight planes in $\mathbb{P}^3$ does {\em not} have this property. We show furthermore that the monodromy group of a good family is Zariski dense in the corresponding symplectic group. Moreover, we study a natural sublocus which we call hyperelliptic locus, over which the variation of Hodge structures is naturally isomorphic to wedge product of a variation of Hodge structures of weight one. It turns out the hyperelliptic locus does not extend to a Shimura subvariety of type III (Siegel space) within the moduli space. Besides general Hodge theory, representation theory and computational commutative algebra, one of the proofs depends on a new result on the tensor product decomposition of complex polarized variations of Hodge structures.

Adsorption of a carboxylated silane on gold : characterization and application to PDMS-based electrochemical cells
Creators: name: Yang, Cheng Wei Tony
Publisher: name: University of British Columbia
Year: 2017

description: Integrated sensing and biosensing microfluidic systems often require sealing between polydimethylsiloxane (PDMS), glass, and gold interfaces. Studying substances that can self-organize onto glass and gold surfaces may achieve these goals and pave the way for new technological advances. Work presented in this thesis focuses on characterizing the adsorption of N-[(3-trimethoxysilyl)propyl]ethylene-diamine triacetic acid (or TMS-EDTA) on Au and applying this knowledge to construct leak-free PDMS-based electrochemical cells. First, surface analysis of TMS-EDTA-modified Au surfaces was conducted using various techniques. Water contact angle measurements and X-ray photoelectron spectroscopy confirm that the carboxylated silane can chemically modify Au surfaces. Atomic force microscopy studies indicate that a uniform surface coverage with monolayer thickness is formed. Infrared spectroscopy studies indicate that there is little evidence of siloxane cross-linking. Surface plasmon resonance results suggest that the carboxylates on TMS-EDTA-modified Au are available for streptavidin immobilization. Second, electrochemistry was used to determine the Gibbs free energies of adsorption of TMS-EDTA on Au under aqueous conditions. Electrochemical differential capacitance measurements reveal that the potential-dependent free energies of adsorption are ∼ - 20 to - 30 kJ/mol (for potentials between - 0.5 and 0.2 V) in the complex electrolyte solution used. Furthermore, at highly negative potentials ( ∼ - 1.1 V), TMS-EDTA adsorbs minimally onto the Au surface. Third, PDMS surfaces were functionalized to present primary amino groups, and glass or gold slides were functionalized to present carboxyl groups. Strong bonding was achieved by bringing the two surfaces in contact and reacting at room temperature. Shear tests reveal that the novel carboxyl-amine bonding strategy achieved a comparable bond strength as the conventional methods. Subsequently, TMS-EDTA was applied to construct leak-free PDMS-based electrochemical cells. Pressure leak tests were conducted to provide a more realistic measure of the bond strengths under aqueous conditions. A method to electrochemically remove the adsorbed TMS-EDTA layer off of the Au electrode, while maintaining the sealed cell chamber, was also developed. The characterization studies and fabrication strategy presented have led to the development of leak-free PDMS-based electrochemical devices that are suitable for sensing and biosensing applications.

description: We study experimentally and theoretically the effects of disorder, nonlinear screening, and magnetism in semiconductor heterostructures containing a $δ$-layer of Mn, where the charge carriers are confined within a quantum well and hence both ferromagnetism and transport are two-dimensional (2D) and differ qualitatively from their bulk counterparts. Anomalies in the electrical resistance observed in both metallic and insulating structures can be interpreted as a signature of significant ferromagnetic correlations. The insulating samples turn out to be the most interesting as they can give us valuable insights into the mechanisms of ferromagnetism in these heterostructures. At low charge carrier densities, we show how the interplay of disorder and nonlinear screening can result in the organization of the carriers in the 2D transport channel into charge droplets separated by insulating barriers. Based on such a droplet picture and including the effect of magnetic correlations, we analyze the transport properties of this set of droplets, compare it with experimental data, and find a good agreement between the model calculations and experiment. Our analysis shows that the peak or shoulder-like features observed in temperature dependence of resistance of 2D heterostructures $δ$-doped by Mn lie significantly below the Curie temperature $T_{C}$ unlike the three-dimensional case, where it lies above and close to $T_{C}$. We also discuss the consequences of our description for understanding the mechanisms of ferromagnetism in the heterostructures under study.

description: The WASP (Wide Angle Search for Planets) project is an exoplanet transit survey that has been automatically taking wide field images since 2004. Two instruments, one in La Palma and the other in South Africa, continually monitor the night sky, building up light curves of millions of unique objects. These light curves are used to search for the characteristics of exoplanetary transits. This first public data release (DR1) of the WASP archive makes available all the light curve data and images from 2004 up to 2008 in both the Northern and Southern hemispheres. A web interface (www.wasp.le.ac.uk/public/) to the data allows easy access over the Internet. The data set contains 3 631 972 raw images and 17 970 937 light curves. In total the light curves have 119 930 299 362 data points available between them.

Cuticular wax analyses with high spatial and temporal resolution lead to the identification and characterization of novel wax biosynthesis genes in Arabidopsis thaliana
Creators: name: Hegebarth, Daniela
Publisher: name: University of British Columbia

description: Plant cuticles seal above-ground organs against non-stomatal water loss, and therefore are vital for survival on land. Besides providing a transpiration barrier, cuticles have important secondary functions, for example to protect from harmful UV radiation, and to provide a self-cleaning mechanism and mechanical support. Cuticles consist of aliphatic very-long-chain wax compounds (C₂₄ to C₃₈) and a cutin polymer. The diversity of cuticular wax compositions across the plant kingdom but also between different organs and ontogenetic stages is remarkable, yet the regulating mechanisms and function of those chemical differences are largely unknown. In the study presented here, a new approach was used, increasing temporal and spatial resolution and integration of chemical wax analyses with analyses of gene expression patterns of wax biosynthesis genes, using Arabidopsis thaliana as a model organism. The aims of the study were to, first, monitor wax composition and gene expression as a function of leaf development as well as different epidermal cell types and, second, to use this information to identify new wax biosynthesis genes. In the second chapter, high temporal resolution was used to follow the dynamics of wax chemistry and gene expression during development of Arabidopsis thaliana leaves, and I was able to link changes in wax chemistry to differential expression of the elongation enzyme KCS6/CER6. In the third chapter, wax analyses and gene expression data with high spatial resolution were acquired, and I identified differences between Arabidopsis epidermal cell types in wax composition and gene expression. Trichomes had a higher abundance of longer chain waxes (C₃₂ to C₃₈) compared to pavement cells, and the KCS5, KCS8 and KCS16 elongation enzymes were identified as candidates for the elongation of C₃₄₊ waxes. In the fourth chapter, I characterized the Arabidopsis condensing enzyme KCS16 and was able to show that it is functioning on the wax elongation pathway, elongating C₃₄ to C₃₈ acyl-CoA wax precursors, mainly in trichomes but also in pavement cells.

description: Rarement intelligibles, les restes organiques minéralisés représentent un potentiel informatif sous-estimé. Directement liés à l’étude de l’objet archéologique en métal qui leur sert de support et a permis leur conservation, ils constituent un champ d’investigation quasi inépuisable et d’une grande diversité. La complexité intrinsèque des matériaux, la variabilité des dégradations possibles, la prise en compte des contextes d’enfouissement impliquent, cependant, de repenser la chaîne opératoire de l’archéologie, depuis la prescription de fouille jusqu’aux lieux de conservation définitifs des biens mobiliers. L’interdisciplinarité et la nécessaire dynamique d’interaction entre les opérateurs de terrain, les conservateurs-restaurateurs, les services de l’État et les spécialistes des matériaux organiques garantissent la réussite de la démarche. Les résultats obtenus par cette approche multidisciplinaire seront illustrés par l’exemple de la nécropole mérovingienne de Merxheim (Haut-Rhin).
description: Rarely intelligible, mineralized organic residues represent an underestimated information potential: their analysis reveals a universe of rare diversity. Directly linked to the study of the archaeological metal artifact that serves as a support and allowed their preservation, they constitute an almost inexhaustible field of investigation. The intrinsic complexity of the materials, the variability of possible degradation, the taking into account of burial contexts, however, imply rethinking the operational chain of archeology, from the prescription of the archaeological excavation to the final places of conservation of movable property. Interdisciplinarity and the necessary dynamic of interaction between field operators, conservators-restorers, state services and organic materials specialists guarantee the success of the process. The results obtained by this multidisciplinary approach will be illustrated by the example of the Merovingian necropolis of Merxheim (Haut-Rhin).

description: The aim of the ArDM project is the development and operation of a one ton double-phase liquid argon detector for direct Dark Matter searches. The detector measures both the scintillation light and the ionization charge from ionizing radiation using two independent readout systems. This paper briefly describes the detector concept and presents preliminary results from the ArDM R&D program, including a 3 l prototype developed to test the charge readout system.

The Bosma effect revisited - I. HI and stellar disc scaling models

description: The observed proportionality between the centripetal contribution of the dynamically insignificant HI gas in the discs of spiral galaxies and the dominant contribution of DM - the "Bosma effect" - has been repeatedly mentioned in the literature but largely ignored. We have re-examined the evidence for the Bosma effect by fitting Bosma effect models for 17 galaxies in the THINGS data set, either by scaling the contribution of the HI gas alone or by using both the observed stellar disc and HI gas as proxies. The results are compared with two models for exotic cold DM: internally consistent cosmological NFW models with constrained compactness parameters, and URC models using fully unconstrained Burkert density profiles. The Bosma models that use the stellar discs as additional proxies are statistically nearly as good as the URC models and clearly better than the NFW ones. We thus confirm the correlation between the centripetal effects of DM and that of the interstellar medium of spiral galaxies. The edificacy of "maximal disc" models is explained as the natural consequence of "classic" Bosma models which include the stellar disc as a proxy in regions of reduced atomic gas. The standard explanation - that the effect reflects a statistical correlation between the visible and exotic DM - seems highly unlikely, given that the geometric forms and hence centripetal signatures of spherical halo and disc components are so different. A literal interpretation of the Bosma effect as being due to the presence of significant amounts of disc DM requires a median visible baryon to disc DM ratio of about 40%.

TeV Flux modulation in PSR B1259-63/LS 2883
Creators: name: Kerschhaggl, Matthias
Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: PSR B1259-63/LS 2883 is a binary system where a 48 ms pulsar orbits a massive Be star with a highly eccentric orbit (e=0.87) with a period of 3.4 years. The system exhibits variable, non-thermal radiation visible from radio to very high energies (VHE) around periastron passage. This radiation is thought to originate from particles accelerated in the shock region between the pulsar wind (PW) and stellar outflows. The consistency of the H.E.S.S. data with the inverse Compton (IC) scenario is studied in the context of dominant orbital phase dependent adiabatic losses. The dependence of the observed TeV flux with the separation distance is analyzed. Model calculations based on IC scattering of shock accelerated PW electrons and UV photons are performed. Different non-radiative cooling profiles are suggested for the primary particle population to account for the variable TeV flux. The TeV fluxes obtained with H.E.S.S. in the years 2004 and 2007 seem to be only dependent on the binary separation. The presented results hint at a peculiar non-radiative cooling profile around periastron dominating the VHE emission in PSR B1259-63. The location of the stellar disc derived from this non-radiative cooling profile is in good agreement with that inferred from radio observations.
