description: The dependence of macroscopic radiation pressure on the velocity of the object being pushed is commonly attributed to the Doppler effect. This need not be the case, and here we highlight velocity dependent radiation pressure terms that have their origins in the mixing of s and p polarizations brought about by the Lorentz transformation between the lab and the material rest frame, rather than in the corresponding transformation of frequency and wavevector. The theory we develop is relevant to the nano-optomechanics of moving bodies.

description: We calculate the optical spectra of silicon and germanium in the adiabatic time-dependent density functional formalism, making use of kinetic energy density-dependent (meta-GGA) exchange-correlation functionals. We find excellent agreement between theory and experiment. The success of the theory on this notoriously difficult problem is traced to the fact that the exchange-correlation kernel of meta-GGA supports a singularity of the form $α/q^2$ (where $q$ is the wave-vector and $α$ is a constant), whereas previously employed approximations (e.g. local density and generalized gradient approximations) do not. Thus, the use of the adiabatic meta-GGA opens a new path for handling the extreme non-locality of the time-dependent exchange-correlation potential in solid-state systems.

description: Edible City Solutions (ECS) are recognized by city representatives for their potential to contribute
 to addressing key socio‐economic and environmental challenges. Differences in local context,
 however, shape local priorities and thus the best locally‐ suited mechanisms for integrating ECS
 in local planning.
 In larger cities, there is a growing demand for policy action from citizens, which are involved in a
 multitude of community‐based ECS. In some cities ECS initiatives have already benefited from a
 wide range of existing supportive programs. Information on existing opportunities, however, is
 hard to access. Furthermore, many ECS initiatives are threatened by uncertainty in the context of
 competing demands for scarce land. Yet, strategies for ensuring their long‐term sustainability are
 generally lacking. ECS are often seen as a fashion among other urban trends. City administrations
 are beginning to experiment with both vertical (borough, district, city‐wide) and horizontal (crosssectoral)
 modes of coordination involving a wide range of stakeholders. Furthermore, new ways
 of facilitating access to information are being explored. However, existing processes often lack
 broad‐based citizen involvement, which is a challenge that needs to be addressed.
 In smaller cities, where land for agricultural production is more easily accessible, ECS policy integration
 tends to be a municipal‐led endeavour aimed to create awareness and knowledge on
 environmental problems, revitalizing the local economy and enhancing opportunities for special
 target groups. Some local administrations have begun to experiment with the use of ECS
 implementation as a strategy for the social integration of long‐term unemployed and youth.
 However, effective strategies for the engagement of marginal groups need to be better explored. ...Read more in the document

The genetic basis for adrenal gland structure : a focus on the stress response
Creators: name: Di Curzio, Domenico Luciano
Publisher: name: University of British Columbia
Year: 2009

description: Adrenal gland function is mediated through secreted hormones, and these hormones play a vital role in the autonomic and HPA-axis mediated stress response. Stress is a complex phenomenon, and the genetic underpinnings of it can be approached using a quantitative trait locus (QTL) analysis. This method has been used to investigate genomic regions associated with variation in complex phenotypes in the mouse CNS and anatomical variation in organ weights. However, it has not been previously used to explore the structure of the adrenal gland. In this study, we used QTL analyses to identify candidate genes underlying adrenal weight and adrenal cortical zones and medulla widths. We used 64 BXD recombinant inbred (RI) strains of mice (n = 571) and 2 parental strains (C57BL/6J and DBA/2J; n = 20) to measure adrenal weights. These 64 BXD RI strains and the progenitor strains were then examined to measure adrenal zone widths. We performed QTL linkage analysis (with WebQTL) to identify QTLs associated with adrenal weight. We found significant QTLs on chromosome 3 for females and Chr 4 for males and suggestive QTLs on Chrs 1, 3, 10, and 14 for females and Chrs 2, 4, 10, 17, and X for males. We identified a significant QTL on Chr 10 and a suggestive QTL on Chr 13 for male adrenal total width. For male adrenal medulla width, we found a significant QTL on Chr 5 and a suggestive QTL on Chr 1. In addition, we identified significant QTLs on Chrs 10 and 14 for male X-zone width. Finally, there are 114 genes that mapped within the significant QTL intervals, of which we identified 5 candidate genes associated with adrenal structure and/or function. In summary, this study is an important first step for detecting genetic factors influencing the structure of the adrenal component of the HPA-axis using QTL analysis, which may relate to adrenal function and provide further insights into elucidating genes critical for stress-related phenotypes.

description: We investigate the quasiparticle band structure of anatase TiO2, a wide gap semiconductor widely employed in photovoltaics and photocatalysis. We obtain GW quasiparticle energies starting from density-functional theory (DFT) calculations including Hubbard U corrections. Using a simple iterative procedure we determine the value of the Hubbard parameter yielding a vanishing quasiparticle correction to the fundamental band gap of anatase TiO2. The band gap (3.3 eV) calculated using this optimal Hubbard parameter is smaller than the value obtained by applying many-body perturbation theory to standard DFT eigenstates and eigenvalues (3.7 eV). We extend our analysis to the rutile polymorph of TiO2 and reach similar conclusions. Our work highlights the role of the starting non-interacting Hamiltonian in the calculation of GW quasiparticle energies in TiO2, and suggests an optimal Hubbard parameter for future calculations.

Here we report the first laboratory experiment of a shallow water analogue, based on the physics of hydraulic jumps. Both the experiment and its shallow water modeling demonstrate a robust linear instability and nonlinear properties of symmetry breaking, in a system which is one million times smaller and about hundred times slower than its astrophysical analogue.

description: The problem of calculation of correlation functions in the six-vertex model with domain wall boundary conditions is addressed by considering a particular nonlocal correlation function, called row configuration probability. This correlation function can be used as building block for computing various (both local and nonlocal) correlation functions in the model. The row configuration probability is calculated using the quantum inverse scattering method; the final result is given in terms of a multiple integral. The connection with the emptiness formation probability, another nonlocal correlation function which was computed elsewhere using similar methods, is also discussed.

description: Many of the Edible City Solutions (ECS) supported by EdiCitNet have the potential to develop and provide more competitive products or services. These potential scenarios include the entire value-chain of food production, distribution and consumption as well as related services such as environmental education. Bringing ECS to global and local markets is a key-element of the project’s up-scaling and knowledge transfer strategy. For this reason, EdiCitNet is developing an online marketplace for ECS business development as an integral part of the EdiCitNet public website. The goal is to connect ECS, entrepreneurs and interested parties at the local, regional and global level, enabling global knowledge sharing and ECS replication or benefit from other products and services provided by ECS initiative all over the world. The marketplace is built around the opportunities demonstrated in the EdiCitNet Living Labs and beyond. The “EdiCitNet online Marketplace” is designed as an online meeting place to initiate collaborations promoting the replication and marketing of ECS business models, products and services. Furthermore, the marketplace compiles features and tools that allow the support of a growing buyer/seller community of ECS, promote a diversity of ECS products or services, and drive sales. The main objective is to test the impact and the functionality of an ECS marketplace. During the project time, the results and findings of the activities implemented by the Business Consulting Team (BCT) and the work around the valorization of ECS in the project will feed the marketplace and let it grow into an independent platform, serving as the primary trading place for ECS worldwide. The pilot of the marketplace will be constantly updated and thus naturally lead to a stable and independent marketplace surviving even after the project’ end. Our goal is to establish a sustainable platform, independent of the project website.

description: We revisit the problem of the split main sequence (MS) of the globular cluster omega Centauri, and report the results of two-epoch Hubble Space Telescope observations of an outer field, for which proper motions give us a pure sample of cluster members, and an improved separation of the two branches of the main sequence. Using a new set of stellar models covering a grid of values of helium and metallicity, we find that the best possible estimate of the helium abundance of the bluer branch of the MS is Y = 0.39 +/- 0.02. For the cluster center we apply new techniques to old observations: we use indices of photometric quality to select a high-quality sample of stars, which we also correct for differential reddening. We then superpose the color-magnitude diagram of the outer field on that of the cluster center, and suggest a connection of the bluer branch of the MS with one of the more prominent among the many sequences in the subgiant region. We also report a group of undoubted cluster members that are well to the red of the lower MS.

description: Milestone Nr: MS1 First official meetings of EdiCitNet City Teams Milestone lead beneficiary: Royal Melbourne Institute of Technology Spain SL (RMIT) Work package: WP1 Urban Governance and Network Infrastructure Date of achievement: October 2019 Means of verification (DoA): Each FRC and FC will generate an individual EdiCitNet City Team. The EdiCitNet City Teams will include, as a minimum, the municipal government and administration, local civil society and NGO representatives, and private sector (SME) peak bodies. These local decision-making groups will constitute the core of EdiCitNet City Teams and will be responsible for implementing the project in each city. The first official meetings of the individual EdiCitNet City Teams are the beginning of intensive work at the local level. At the same time the foundation is laid for the further development of the superordinated Edible Cities Network. Has this milestone been achieved? Yes. Following on from these iterative and processual steps, we confirm that the first official City Team meetings, signalling the beginning of intensive work at the local level, have been held. These events have been recorded through the minutes of both large meetings and regular smaller check-in meetings with WP1 (RMIT, UBER) and WP4 (BOKU), the latter of whom collaborated with WP1 to combine their efforts to benefit both WP1 and WP4 tasks. A short milestone report is presented in this document.

description: During their main sequence lifetimes, the majority of all Galactic Disc field stars must endure at least one stellar intruder passing within a few hundred AU. Mounting observations of planet-star separations near or beyond this distance suggest that these close encounters may fundamentally shape currently-observed orbital architectures and hence obscure primordial orbital features. We consider the commonly-occurring fast close encounters of two single-planet systems in the Galactic Disc, and investigate the resulting change in the planetary eccentricity and semimajor axis. We derive explicit 4-body analytical limits for these variations and present numerical cross-sections which can be applied to localized regions of the Galaxy. We find that each wide-orbit planet has a few percent chance of escape and an eccentricity that will typically change by at least 0.1 due to these encounters. The orbital properties established at formation of millions of tight-orbit Milky Way exoplanets are likely to be disrupted.

Metalloproteinase cleavage of versican at the fibroblast cell surface
Creators: name: Maurice, Sean Bertram
Publisher: name: University of British Columbia
Year: 2009

description: Versican is a large aggregating proteoglycan expressed in the pericellular matrix of fibroblast cells. It is highly expressed during development and remodeling. The regulated synthesis and degradation of versican are associated with physiological remodeling. Versican is expressed in fibroproliferative lesions of human pulmonary fibrosis and atherosclerosis. Stromal expression of versican is associated with many forms of cancer and may be predictive of poor prognosis. Abnormal persistence of the versican-rich matrix may contribute to fibroproliferative and oncogenic processes. The process of versican degradation is not understood, but as versican is a pericellular molecule, physiological degradation likely involves cell surface-associated proteolysis. As such, the overarching hypothesis for this work is that regulated versican turnover involves the cell surface-associated metalloproteinases ADAMTS-2, MMP-2 and MT1-MMP, that are expressed in versican-rich remodeling lesions. ADAMTS-2 is a procollagen N-propeptidase involved in collagen fibrillogenesis. As procollagen is synthesized in a versican-rich matrix, it was hypothesized that ADAMTS- 2 might bind and process versican. MMP-2 and MT1-MMP in complex with TIMP-2, are activated at the cell surface during wound healing, pulmonary fibrosis and cancer. Versican was purified from human fetal lung fibroblast cultures for in vitro proteolysis experiments. The purified versican preparation was characterized by electrophoresis, chromatography, spectrophotometry and mass spectrometry. ADAMTS-2 and versican localization in normal and fibrotic human lungs were investigated. ADAMTS-2 was shown to co-purify with versican from human fetal lung fibroblasts. Bovine ADAMTS-2 was purified from fetal calf skin and shown to cleave purified human versican. The plant lectin concanavalin-A (ConA) induces a matrix degradative phenotype and is used here to investigate the process of versican degradation relative to apoptotic iii events in human fetal lung fibroblast cultures. Con-A induced increased expression of MMP-2 and MT1-MMP in human fetal lung fibroblasts and a concomitant loss of versican from the matrix. Microarray analysis was used to investigate expression of possible versican-degrading enzymes and their inhibitors, expressed in response to ConA. Recombinant MMP-2 and MT1-MMP were shown to process purified versican in vitro. This work expands upon the body of knowledge of versican turnover and should help in the search for therapeutic avenues to treat fibroproliferative and oncogenic processes.

description: It is well-known that $f(R)$ gravity models formulated in Einstein conformal frame are equivalent to Einstein gravity together with a minimally coupled scalar field. In this case, the scalar field couples with the matter sector and the coupling term is given by the conformal factor. We apply the holographic principle to such interacting models. In a spatially flat universe, we show that the Einstein frame representation of $f(R)$ models leads to a constant ratio of energy densities of dark matter to dark energy.

description: We give an explicit construction of the cusp eigenforms on an elliptic curve defined over a finite field using the theory of Hall algebras and the Langlands correspondence for function fields and $\GL_n$. As a consequence we obtain a description of the Hall algebra of an elliptic curve as an infinite tensor product of simpler algebras. We prove that all these algebras are specializations of a universal spherical Hall algebra (as defined and studied in \cite{BS} and \cite{SV1}).

description: The duality of information overload and underload is a defining issue of our age. Scholarly information is abundant but not universally accessible to all scholars and learners, thereby hindering or prohibiting equitable engagement in ongoing scholarly conversations. Access is a core aspect of the issue of overload and underloadâ€”both access to research materials and access to venues where one can contribute to the scholarly corpusâ€”but it is not the only aspect. Our group agreed that the problem of overload is preferable to that of underload; however, the dual nature of the issue makes that conclusion more nuanced, dynamic, and situational. In this report we explore the many factors and causes of information overload and underload and also develop ideas for solutions. A summary of the issues is provided.
OSI2016 Workgroup Question
Information underload occurs when we donâ€™t have access to the information we need (for a variety of reasons, including cost)â€”researchers based at smaller institutions and in the global peÂ­riphery, policymakers, and the general public, particularly with regard to medical research. Overload occurs when we can access everything but are simply overwhelmed by the torrent of information available (not all of which is equally valuable). Are these issues two sides of the same coin? In both cases, how can we work together to figure out how to get people the information they need? Can we? How widespread are these issues? What are the economic and research consequences of information underload and overload?

description: Quantum error correction in general is experimentally challenging as it requires significant expansion of the size of quantum circuits and accurate performance of quantum gates to fulfill the error threshold requirement. Here we propose a method much simpler for experimental implementation to correct arbitrary detection errors. The method is based on processing of data from repetitive experiments and can correct detection error of any magnitude, as long as the error magnitude is calibrated. The method is illustrated with its application to detection of multipartite entanglement from quantum state engineering.

description: The top triangle moose $(TTM)$ model, which can be seen as the deconstructed version of the topcolor-assisted technicolor ($TC2$) model, predicts the existence of the charged top-pions $ π_{t}^{\pm}$ in low energy spectrum. In the context of this model, we consider photoproduction of $π^{\pm}_{t}$ via the subprocesses $γb\to t π_{t}^{-}$ and $γ\bar{b}\to \bar{t} π_{t}^{+}$ at the large hadron-electron collider ($LHeC$), in which high energy photon beams are generated by using the Compton backscatting method. We find that, as long as the charged top-pions are not too heavy, they can be abundantly produced via $γb$ collision.

A simple model based on first principles and depending on a single free parameter is able to reproduce J/psi suppression data at large xF and at various center-of-mass energies. These results strongly support energy loss as a dominant effect in quarkonium suppression. They also give some hint on its hadroproduction mechanism suggesting color neutralization to happen on long time-scales. Predictions for J/psi and Upsilon suppression in p-Pb collisions at the LHC are made.

A numerical and experimental investigation into pressure screen foil rotor hydrodynamics
Creators: name: Delfel, Sean
Publisher: name: University of British Columbia

description: Pressure screens are an effective way to remove contaminants from a pulp stream and to fractionate the pulp, or separate the fibres by length, both of which improve the quality of the end-product paper. In this thesis, seven experimental and numerical studies were conducted to investigate the hydrodynamics of pressure screen foil rotors and the effects of rotor design on the overall performance of a pressure screen. Additionally, this knowledge was applied to the development of a high performance foil rotor for both out-flow and in-flow screens. A multi-element foil rotor was developed using computational fluid dynamics (CFD), laboratory experiments, pilot plant trials, and a full scale mill trial. It was found that varying the shape and configuration of the foil affected both the pressure pulses generated by the rotor and the maximum capacity of the pressure screen. The multi-element foil (MEF) was found to be capable of generating a 126% higher magnitude negative pressure pulse, a 31% increase in screen capacity at a given rotor power consumption and a 43% reduction in power consumption without affecting capacity compared to state of the art single element rotors. The effect of varying the frequency of the pressure pulses, by changing the number of foils on the rotor, the diameter of the cylinder, and slot velocity on rotor performance was also studied. Adding foils to the rotor was found to reduce the velocity of the fluid relative to the foils and the magnitude of the pressure pulses generated by the rotors, leading to a reduction in overall screen performance. Increasing the diameter of the screen slightly reduces the performance of the foils. Increasing slot velocity did not affect the pressure pulses generated by the rotor for fully attached flows, but caused the foils to stall and a higher tip speed. Finally, factors affecting rotor power consumption other than rotor speed were investigated experimentally and analytically. The cylinder slot geometry, flow rates, and the design of the inlet to the screen were all found to have significant effects on rotor power consumption.
An HI column density threshold for cold gas formation in the Galaxy

description: We report the discovery of a threshold in the HI column density of Galactic gas clouds below which the formation of the cold phase of HI is inhibited. This threshold is at $N_{HI} = 2 \times 10^{20}$ per cm$^{2}$; sightlines with lower HI column densities have high spin temperatures (median $T_s \sim 1800$ K), indicating low fractions of the cold neutral medium (CNM), while sightlines with $N_{HI} \ge 2 \times 10^{20}$ per cm$^{2}$ have low spin temperatures (median $T_s \sim 240$ K), implying high CNM fractions. The threshold for CNM formation is likely to arise due to inefficient self-shielding against ultraviolet photons at lower HI column densities. The threshold is similar to the defining column density of a damped Lyman-$α$ absorber; this indicates a physical difference between damped and sub-damped Lyman-$α$ systems, with the latter class of absorbers containing predominantly warm gas.

Buildup of Magnetic Shear and Free Energy During Flux Emergence and Cancellation

description: We examine a simulation of flux emergence and cancellation, which shows a complex sequence of processes that accumulate free magnetic energy in the solar corona essential for the eruptive events such as coronal mass ejections (CMEs), filament eruptions and flares. The flow velocity at the surface and in the corona shows a consistent shearing pattern along the polarity inversion line (PIL), which together with the rotation of the magnetic polarities, builds up the magnetic shear. Tether-cutting reconnection above the PIL then produces longer sheared magnetic field lines that extend higher into the corona, where a sigmoidal structure forms. Most significantly, reconnection and upward energy-flux transfer are found to occur even as magnetic flux is submerging and appears to cancel at the photosphere. A comparison of the simulated coronal field with the corresponding coronal potential field graphically shows the development of nonpotential fields during the emergence of the magnetic flux and formation of sunspots.

description: We report on the long-term dynamical evolution of the two-planet Kepler-36 system, which we studied through numerical integrations of initial conditions that are consistent with observations of the system. The orbits are chaotic with a Lyapunov time of only ~10 years. The chaos is a consequence of a particular set of orbital resonances, with the inner planet orbiting 34 times for every 29 orbits of the outer planet. The rapidity of the chaos is due to the interaction of the 29:34 resonance with the nearby first order 6:7 resonance, in contrast to the usual case in which secular terms in the Hamiltonian play a dominant role. Only one contiguous region of phase space, accounting for ~4.5% of the sample of initial conditions studied, corresponds to planetary orbits that do not show large scale orbital instabilities on the timescale of our integrations (~200 million years). The long-lived subset of the allowed initial conditions are those that satisfy the Hill stability criterion by the largest margin. Any successful theory for the formation of this system will need to account for why its current state is so close to unstable regions of phase space.

description: Durch die zunehmenden Anforderungen an Leichtbaukonstruktionen motiviert, ist das Ziel ungleichartige Ti- und γ-TiAl-Ti-Legierungs-Verbindungen aus Blechen rissfrei mittels Laserstrahlschweißen herzustellen. Dies wurde durch Vorheizen erreicht. Die Rissentstehung konnte der Mikrostruktur-Phasen-Entwicklung zugeordnet werden. Der Einfluss der Grenzfläche auf den Versagensort und die Zugeigenschaften wurde durch Zugversuche ermittelt. Zudem wurde das gewonnene Wissen bezüglich der Mikrostruktur-Phasen-Entwicklung an der Grenzfläche erfolgreich auf laserauftragsgeschweißte Strukturen übertragen und die Grenzen der Übertragbarkeit bezüglich der Rissbildung aufgezeigt. Folglich wurden die Grundlagen der Herstellung rissfreier γ-TiAl-Ti-Legierungs-Verbindungen erarbeitet.
description: Motivated by the increasing demands for lightweight constructions, the aim is to obtain crack-free dissimilar Ti- and γ-TiAl-Ti-alloy joints by focusing on laser beam welding as the joining method. This was successfully achieved by preheating and the crack formation could be correlated to the microstructure-phase evolution. Through tensile tests the influence of the dissimilar interface on the fracture position and tensile properties could be revealed. Extending the thesis, the gained knowledge regarding the microstructure-phase evolution at the interface could be successfully transferred to the laser metal dep-ositions. Besides, the limited transferability concerning the crack formation was demonstrated. Hence, the fundamentals for crack-free γ-TiAl-Ti-alloy joints and depositions were established.

description: We study the mixing time of random graphs in the $d$-dimensional toric unit cube $[0,1]^d$ generated by the geographical threshold graph (GTG) model, a generalization of random geometric graphs (RGG). In a GTG, nodes are distributed in a Euclidean space, and edges are assigned according to a threshold function involving the distance between nodes as well as randomly chosen node weights, drawn from some distribution. The connectivity threshold for GTGs is comparable to that of RGGs, essentially corresponding to a connectivity radius of $r=(\log n/n)^{1/d}$. However, the degree distributions at this threshold are quite different: in an RGG the degrees are essentially uniform, while RGGs have heterogeneous degrees that depend upon the weight distribution. Herein, we study the mixing times of random walks on $d$-dimensional GTGs near the connectivity threshold for $d \geq 2$. If the weight distribution function decays with $\mathbb{P}[W \geq x] = O(1/x^{d+ν})$ for an arbitrarily small constant $ν>0$ then the mixing time of GTG is $\mixbound$. This matches the known mixing bounds for the $d$-dimensional RGG.
