description: Fusarium graminearum is a devastating pathogen of small grain cereals causing both Fusarium head blight (FHB) and Fusarium root rot (FRR). Exogenous application of phytohormones has been shown to affect FHB resistance. In contrast to FHB, FRR remains poorly characterised and it is unknown whether phytohormones play similar roles in FHB and FRR. In this present study, B. distachyon floral tissues at mid-anthesis and root tissues from seedlings were exogenously treated with several phytohormones before inoculation with F. graminearum. The canonical defence-associated phytohormones had differing effects on FHB and FRR. Salicylic acid (SA) significantly increased susceptibility to FRR but not to FHB while jasmonic acid (JA) and ethylene increased resistance to FRR but increased susceptibility to FHB. Additionally, the growth-associated phytohormones auxin and cytokinin significantly increased resistance and susceptibility, respectively, to both diseases. This study is the first to compare phytohormone effects between FHB and FRR in the same host. Highlight The tissue-dependent effects of defence phytohormones and tissue-independent effects of development phytohormones on F. graminearum-induced Fusarium head blight and Fusarium root rot diseases in the model cereal Brachypodium distachyon.

description: As modified gravity theories, the 4-dimensional metric $f(R)$ theories are cast into connection dynamical formalism with real $su(2)$-connections as configuration variables. This formalism enables us to extend the non-perturbative loop quantization scheme of general relativity to any metric $f(R)$ theories. The quantum kinematical framework of $f(R)$ gravity is rigorously constructed, where the quantum dynamics can be launched. Both Hamiltonian constraint operator and master constraint operator for $f(R)$ theories are well defined. Our results show that the non-perturbative quantization procedure of loop quantum gravity are valid not only for general relativity but also for a rather general class of 4-dimensional metric theories of gravity.

As power systems evolve, there is a confluence of new technologies and extreme weather events. Uncertainty id a key factor of how we will plan and operate the power system, and we need new tools and methods. With increasing man-made threats, and the impact of supply chain disruptions the issue becomes more pressing. This session will discuss tools and methods for managing uncertainty, and how the industry needs to change to respond to changes in supply, demand and delivery.

description: Images convey a broad spectrum of personal information. If such images are shared on social media platforms, this personal information is leaked which conflicts with the privacy of depicted persons. Therefore, we aim for automated approaches to redact such private information and thereby protect privacy of the individual. By conducting a user study we find that obfuscating the image regions related to the private information leads to privacy while retaining utility of the images. Moreover, by varying the size of the regions different privacy-utility trade-offs can be achieved. Our findings argue for a "redaction by segmentation" paradigm. Hence, we propose the first sizable dataset of private images "in the wild" annotated with pixel and instance level labels across a broad range of privacy classes. We present the first model for automatic redaction of diverse private information. It is effective at achieving various privacy-utility trade-offs within 83% of the performance of redactions based on ground-truth annotation.

description: In the present paper we consider a quantum memory scheme for light diffusely propagating through a spatially disordered atomic gas. The diffuse trapping of the signal light pulse can be naturally integrated with the mechanism of stimulated Raman conversion into a long-lived spin coherence. Then the quantum state of the light can be mapped onto the disordered atomic spin subsystem and can be stored in it for a relatively long time. The proposed memory scheme can be applicable for storage of the macroscopic analog of the $Ψ^{(-)}$ Bell state and the prepared entangled atomic state performs its quantum hologram, which suggests the possibility of further quantum information processing.

description: The two-dimensional layer of molybdenum disulfide (MoS2) has recently attracted much interest due to its direct-gap property and potential applications in optoelectronics and energy harvesting. However, the synthetic approach to obtain high quality and large-area MoS2 atomic thin layers is still rare. Here we report that the high temperature annealing of a thermally decomposed ammonium thiomolybdate layer in the presence of sulfur can produce large-area MoS2 thin layers with superior electrical performance on insulating substrates. Spectroscopic and microscopic results reveal that the synthesized MoS2 sheets are highly crystalline. The electron mobility of the bottom-gate transistor devices made of the synthesized MoS2 layer is comparable with those of the micromechanically exfoliated thin sheets from MoS2 crystals. This synthetic approach is simple, scalable and applicable to other transition metal dichalcogenides. Meanwhile, the obtained MoS2 films are transferable to arbitrary substrates, providing great opportunities to make layered composites by stacking various atomically thin layers.

description: We revisit the problem of the electromagnetic Green function for homogeneous hyperbolic media, where longitudinal and transverse components of the dielectric permittivity tensor have different signs. We analyze the dipole emission patterns for both dipole orientations with respect to the symmetry axis and for different signs of dielectric constants, and show that the emission pattern is highly anisotropic and has a characteristic cross-like shape: the waves are propagating within a certain cone and are evanescent outside this cone. We demonstrate the coexistence of the cone-like pattern due to emission of the extraordinary TM-polarized waves and elliptical pattern due to emission of ordinary TE-polarized waves. We find a singular complex term in the Green function, proportional to the $δ-$function and governing the photonic density of states and Purcell effect in hyperbolic media.

Long-Term On-Board Prediction of People in Traffic Scenes under Uncertainty

description: Progress towards advanced systems for assisted and autonomous driving is leveraging recent advances in recognition and segmentation methods. Yet, we are still facing challenges in bringing reliable driving to inner cities, as those are composed of highly dynamic scenes observed from a moving platform at considerable speeds. Anticipation becomes a key element in order to react timely and prevent accidents. In this paper we argue that it is necessary to predict at least 1 second and we thus propose a new model that jointly predicts ego motion and people trajectories over such large time horizons. We pay particular attention to modeling the uncertainty of our estimates arising from the non-deterministic nature of natural traffic scenes. Our experimental results show that it is indeed possible to predict people trajectories at the desired time horizons and that our uncertainty estimates are informative of the prediction error. We also show that both sequence modeling of trajectories as well as our novel method of long term odometry prediction are essential for best performance.

description: We present moderate resolution (R $\sim$ 3575) optical spectra of 19 known or suspected members of the AB Doradus and $β$ Pictoris Moving Groups, obtained with the DeVeny Spectrograph on the 72-inch Perkins telescope at Lowell Observatory. For 4 of 5 recently proposed members, signatures of youth such as Li\,I 6708 Å\, absorption and H$α$ emission further strengthen the case for youth and membership. Effective temperatures are determined via line ratio analyses for the 11 F, G and early K stars observed, and via spectral comparisons for the 8 late-K and M stars observed. We assemble updated candidate membership lists for these Moving Groups that account for known binarity. We then use temperature, luminosity, and distance estimates to predict angular diameters for these stars; the motivation is to identify stars that can be spatially resolved with long-baseline optical/infrared interferometers in order to improve age estimates for these Groups and to constrain evolutionary models at young ages. Considering the portion of the sky accessible to northern hemisphere facilities (DEC $> -30$), 6 stars have diameters large enough to be spatially resolved ($θ> 0.4$ mas) with the CHARA Array; this subsample includes the low mass M2.5 member of AB Dor, GJ 393, which is likely to still be pre-main sequence. For southern hemisphere facilities (DEC $< +30$), 18 stars have diameters larger than this limiting size, including the low mass debris disk star AU Mic (0.72 mas). However, the longest baselines of southern hemisphere interferometers (160-m) are only able to resolve the largest of these, the B6 star $α$ Gru (1.17 mas); proposed long-baseline stations may alleviate the current limitations.

description: Bacterial 1-aminocyclopropane-1-carboxylate (ACC) deaminase is a key factor for alleviating the plant ethylene biosynthesis, which is induced by stress. The ACC deaminase-improved strains of the rice endophytic Bradyrhizobium sp. SUTN9-2, SUTN9-2 (ACCDadap) and SUTN9-2:pMG103::acdRS, exhibit 1.4- and 8.9-fold higher ACC deaminase activity than the wild type, respectively (Sarapat S, Songwattana P, Longtonglang A, Umnajkitikorn K, Girdthai T, Tittabutr P, Boonkerd N, Teaumroong N. 2020. Effects of Increased 1-Aminocyclopropane-1-Carboxylate (ACC) Deaminase Activity in Bradyrhizobium sp. SUTN9-2 on Mung Bean Symbiosis under Water Deficit Conditions. Microbes Environ. 35). The effects of these on rice growth under water deficit conditions were evaluated. The bacterial inoculations reduced ethylene synthesis, leading to a reduction in membrane destruction and the chlorophyll content of rice. Furthermore, the bacterial inoculations improved the leaf relative water content, survival, recovery rates, and improved the crop yield in field conditions. Therefore, the water deficit tolerance of rice was improved by controlling ethylene biosynthesis by improving ACC deaminase activity with endophytic SUTN9-2. Moreover, the SUTN9-2 (ACCDadap) strain can be used as a bio-inoculant under field conditions to enhance rice growth, grain yield, and enhance drought tolerance.

description: Reef-building coral of the Great Barrier Reef demonstrate remarkably synchronized and precise timing of reproduction. They achieve this precision through sophisticated biological clock systems entrained by their local environment. This thesis explores how temperature and lunar light modulates the biological clocks of Acropora millepora by measuring transcriptomic changes with RNA-sequencing. Coral colonies were collected and maintained under artificial lunar light at the Heron Island Research Station under cool and warm temperature treatments corresponding to winter and summer averages at this locale. Individuals were sampled over a 24-hour period during a full lunar month to capture long-term daily profiles of gene expression. It was found that numerous biological clock genes were impacted by temperature and lunar light. Furthermore, temperature and lunar phase altered the expression of interesting hormonal pathways involved in reproductive behaviours. These data will help elucidate the mechanisms underlying the precise timing of reproduction in reef-building coral and the effect that different temperatures have on this process.

description: The electron spin dynamics is studied by time-resolved Kerr rotation in GaAs/AlGaAs quantum wells embedded in a negatively doped-intrinsic-positively doped structures grown on (111)A or (111)B-oriented substrates. In both cases the spin lifetimes are significantly increased by applying an external electric field but this field has to point along the growth direction for structures grown on (111)A and opposite to it for the ones grown on (111)B. This extended electron spin lifetime is the result of the suppression of the D'yakonov-Perel spin relaxation mechanism [Sov. Phys. Solid State 13, 3023 (1972)] due to the cancellation effect of the internal Dresselhaus term [Phys. Rev. 100, 580 (1955)] with the external electric field induced Rashba one [J. Phys. C 17, 6039 (1984)], both governing the conduction band spin-orbit splitting. These results demonstrate the key role played by the growth direction in the design of spintronic devices.

description: Relatively little is known about the physiological significance of betalain pigments. To investigate a possible protective role for betalains (betacyanin), from UV-B irradiation, two cultivars of A. tricolor, Red-Leaf (RL) and Green-Leaf (GL) were obtained and VIGS method was used to produce isogenic derivatives of RL. Short-term responses to UV-B in the leaves were compared with and without detectable betalains. Following exposure, the red and green tissues showed similar decrease in photosynthetic capacity and in the increased production of UV-B stress markers including melatonin, flavonoids, phenolics, and PAL1 and RCD1 gene transcripts. Red tissues showed an increase in photosynthetic pigments under UV-B treatment, whereas the photosynthetic pigments and CAB1 and CAB2 gene transcripts decreased. The responses observed were similar for both high-betacyanin (RL) plants, and green plants (VIGS, GL), from which it was concluded that betacyanin does not have a UV-B protective role in amaranth leaves, under the experimental conditions.
Accurate and Diverse Sampling of Sequences Based on a ``Best of Many'' Sample Objective

description: For autonomous agents to successfully operate in the real world, anticipation of future events and states of their environment is a key competence. This problem has been formalized as a sequence extrapolation problem, where a number of observations are used to predict the sequence into the future. Real-world scenarios demand a model of uncertainty of such predictions, as predictions become increasingly uncertain -- in particular on long time horizons. While impressive results have been shown on point estimates, scenarios that induce multi-modal distributions over future sequences remain challenging. Our work addresses these challenges in a Gaussian Latent Variable model for sequence prediction. Our core contribution is a ``Best of Many'' sample objective that leads to more accurate and more diverse predictions that better capture the true variations in real-world sequence data. Beyond our analysis of improved model fit, our models also empirically outperform prior work on three diverse tasks ranging from traffic scenes to weather data.
The 2010 Winter Olympic Games: (re)framing protest
Creators: name: Van Luijk, Nicolien
Publisher: name: University of British Columbia
Year: 2011

description: Previous research has shown that the organization of Olympic Games has had a negative impact on the civil liberties of host communities, including the right to peaceful protest (Lenskyj, 2002). The purpose of this research was to examine how individuals participating in anti-Olympic events (re)framed the right to protest in public space during the 2010 Vancouver Winter Olympic Games. Three research questions guided the study, (i) what are protestor perspectives on how Olympic organizers are framing this issue (ii) how are protestors re-framing the issue, and (iii) what is their assessment of the challenges encountered? The basis of my theoretical framework is the notion that space is socially constructed and that different actors continuously contest the use of public space (Lefebvre, 1991). In the context of the Olympic Games the use of public space is protected by the dominant actors (e.g., Olympic organizers) and challenged by subordinate actors in the organizational field, in this case those protesting against the Games. This study also drew on the theoretical concepts of institutional logics and framing processes from the Organizational Studies and the Social Movement Theory literature respectively (McAdam & Scott, 2005). These concepts are used to describe the cognitive processes that shaped the behaviours of Olympic organizers and protest participants in relation to the right to protest in public space. The study involved observations of fifteen anti-Olympic events, one-on-one interviews with six protest participants, and an analysis of related documents. The research found that Olympic organizers operated under three major logics of Olympism, security, and sport and nationalism, which framed protestors in ways that delegitimized their perspectives and limited their access to public space. Protest participants re-framed organizer logics by utilizing civil liberties and corporatization as counter-logics to legitimize their right to be present in public spaces during the Games. While the re-framing engaged in by protestors provided some success, the findings suggest that the dominant logics of the Games maintained long-term power and control over spatial practices. The aim of this study was to fill a gap in the existing critical Olympic literature by examining perspectives of protest participants‟ first-hand.

description: The dynamics of an order parameter's amplitude and phase determines the collective behaviour of novel states emerged in complex materials. Time- and momentum-resolved pump-probe spectroscopy, by virtue of its ability to measure material properties at atomic and electronic time scales and create excited states not accessible by the conventional means can decouple entangled degrees of freedom by visualizing their corresponding dynamics in the time domain. Here, combining time-resolved femotosecond optical and resonant x-ray diffraction measurements on striped La1.75Sr0.25NiO4, we reveal unforeseen photo-induced phase fluctuations of the charge order parameter. Such fluctuations preserve long-range order without creating topological defects, unlike thermal phase fluctuations near the critical temperature in equilibrium10. Importantly, relaxation of the phase fluctuations are found to be an order of magnitude slower than that of the order parameter's amplitude fluctuations, and thus limit charge order recovery. This discovery of new aspect to phase fluctuation provides more holistic view for the importance of phase in ordering phenomena of quantum matter.

description: We derive a method to reconstruct Gaussian signals from linear measurements with Gaussian noise. This new algorithm is intended for applications in astrophysics and other sciences. The starting point of our considerations is the principle of minimum Gibbs free energy which was previously used to derive a signal reconstruction algorithm handling uncertainties in the signal covariance. We extend this algorithm to simultaneously uncertain noise and signal covariances using the same principles in the derivation. The resulting equations are general enough to be applied in many different contexts. We demonstrate the performance of the algorithm by applying it to specific example situations and compare it to algorithms not allowing for uncertainties in the noise covariance. The results show that the method we suggest performs very well under a variety of circumstances and is indeed qualitatively superior to the other methods in cases where uncertainty in the noise covariance is present.

description: As more and more personal photos are shared online, being able to obfuscate identities in such photos is becoming a necessity for privacy protection. People have largely resorted to blacking out or blurring head regions, but they result in poor user experience while being surprisingly ineffective against state of the art person recognizers[17]. In this work, we propose a novel head inpainting obfuscation technique. Generating a realistic head inpainting in social media photos is challenging because subjects appear in diverse activities and head orientations. We thus split the task into two sub-tasks: (1) facial landmark generation from image context (e.g. body pose) for seamless hypothesis of sensible head pose, and (2) facial landmark conditioned head inpainting. We verify that our inpainting method generates realistic person images, while achieving superior obfuscation performance against automatic person recognizers.

description: In this paper, we show the scattering and blow-up result of the radial solution with the energy below the threshold for the nonlinear Schrödinger equation (NLS) with the combined terms iu_t + Δu = -|u|^4u + |u|^2u \tag{CNLS} in the energy space $H^1(\R^3)$. The threshold is given by the ground state $W$ for the energy-critical NLS: $iu_t + Δu = -|u|^4u$. This problem was proposed by Tao, Visan and Zhang in \cite{TaoVZ:NLS:combined}. The main difficulty is the lack of the scaling invariance. Illuminated by \cite{IbrMN:f:NLKG}, we need give the new radial profile decomposition with the scaling parameter, then apply it into the scattering theory. Our result shows that the defocusing, $\dot H^1$-subcritical perturbation $|u|^2u$ does not affect the determination of the threshold of the scattering solution of (CNLS) in the energy space.

description: In this paper, we study the homogeneous one-dimensional bosonic gas interacting via a repulsive contact potential by using the improved Gaussian approximation. We obtain the gapless excitation spectrum of Bogoliubov mode. Our result is in good agreement with the exact numerical calculation based on the Bethe ansatz. We speculate that the improved Gaussian approximation could be a quantitatively good approximation for higher dimensional systems.

description: General Relativity can be reformulated as a geometrodynamical theory, called Shape Dynamics, that is not based on spacetime (in particular refoliation) symmetry but on spatial diffeomorphism and local spatial conformal symmetry. This leads to a constraint algebra that is (unlike General Relativity) a Lie algebra, where all local constraints are linear in momenta and may thus be quantized as vector fields on the geometrodynamic configuration space. The Hamiltonian of Shape Dynamics is complicated but admits simple expressions whenever spatial derivatives are negligible.

An empirical approach to interpreting card-sorting data

description: Since it was first published 30 years ago, Chi et al.'s seminal paper on expert and novice categorization of introductory problems led to a plethora of follow-up studies within and outside of the area of physics [Chi et al. Cognitive Science 5, 121 - 152 (1981)]. These studies frequently encompass "card-sorting" exercises whereby the participants group problems. While this technique certainly allows insights into problem solving approaches, simple descriptive statistics more often than not fail to find significant differences between experts and novices. In moving beyond descriptive statistics, we describe a novel microscopic approach that takes into account the individual identity of the cards and uses graph theory and models to visualize, analyze, and interpreting problem categorization experiments. We apply these methods to an introductory physics (mechanics) problem categorization experiment, and find that most of the variation in sorting outcome is not due to the sorter being an expert versus a novice, but rather due to an independent characteristic that we named "stacker" versus "spreader." The fact that the expert-novice distinction only accounts for a smaller amount of the variation may explain the frequent null-results when conducting these experiments.

description: Sugarcane is a leading biofuel crop besides being a source of crystal sugar and biomaterials worldwide. This study chiefly focuses on the role of diazotrophic bacteria isolated from sugarcane rhizosphere exhibiting different plant growth-promoting traits and biocontrol activities. Several bacterial isolates were obtained from the rhizosphere soil samples of four sugarcane cultivars. Out of these, 23 strains were selected and identified by 16S rRNA gene sequencing which confirmed different PGP-traits, biocontrol, and nitrogenase activities with nifH gene amplification. Two prominent strains, Kosakonia radicincitans-BA1 and Stenotrophomonas maltophilia-COA2 were selected for further analysis. Biolog plate assay was used to establish the utilization of various carbon and nitrogen sources and pH and osmotic stress tolerance for both strains. Colonization of selected strains in the sugarcane plant was observed by scanning electron microscopy and confocal laser scanning microscopy exhibited bacterial cells were frequently located in sugarcane tissues. Inoculation of the strains in GT11 and GXB9 cultivars led to a significant increase in growth parameters, nitrogen content, expression of nifH, and stress-related genes under greenhouse conditions. This is the first study to explore K. radicincitans and S. maltophilia as nitrogen-fixing plant growth-promoting rhizobacteria in sugarcane for disease management and reduce the practice of chemical fertilizers.

A Mixed Methods Approach to Identifying Barriers and Supports to Physical Activity in Adults Following Residential Relocation
Creators: name: Salvo, Grazia

Year: 2018
Subjects: subject: physical activity
subject: built environment
subject: Public Health

description: Using a systematized review of qualitative studies and a quasi-longitudinal mixed methods analysis of primary data, this thesis explored the built environment’s influence on physical activity among adults. The systematized review provided insight into functional, aesthetic, destination, and safety characteristics’ that are associated with physical activity. Sociodemographic characteristics were also found to affect the built environment-physical activity relationship. In the mixed methods analysis, quantitative data suggested positive associations between self-reported changes in transportation walking and cycling and improvements in objectively measured neighbourhood walkability (Walk Score®) following residential relocation. Findings from the qualitative semi-structure interviews reinforced the quantitative findings and specifically highlighted the importance of having access to safe walking and cycling paths and nearby destinations that support active transportation. The interview data also suggested neighbourhood opportunities that allow adults to connect with community, family and the environment while being active supported enjoyable physical activity. Notably, some participants also reported using time spent on active transportation to compensate for changes in time spent in leisure physical activity. The thesis findings have the potential to inform urban planning and policy for improving physical activity and in turn health in adult populations.
Theoretical evaluation of replacing residue gas with nitrogen for pressure maintenance in the Wembley halfway B reservoir
Creators: name: Jones, Michael S.

Year: 1990
Subjects: subject: Gas condensate reservoirs

description: Bibliography: p. 62-63.
description: A study into replacing plant residue gas (methane) with cryogenic nitrogen for the purpose of pressure maintenance in the Wembley Halfway B gas cap is presented. The study considers both reservoir simulation of pool processes to determine the recovery of marketable products and the economic modelling of the processes using the Amoco Canada in-house program GOFER. An investigation of equipment requirements is also considered. The study indicates that lower recoveries of all marketable products will result if nitrogen is used to replace methane. Moreover, the economic benefit of early residue gas sales only marginally compensates for lower liquid recoveries. Residue gas cycling at a 75% voidage replacement ratio, injecting 38 MMSCFD of residue gas, had total liquid (ethane plus) recovery of 83%. When an equivalent volume of nitrogen was injected, the recovery dropped to 69%. A similar recovery was realized at nitrogen injection at a 75% voidage replacement ratio.
