Strategies to reduce transportation emissions in India : identifying air quality and climate co-benefits for the developing world
Creators: name: Reynolds, Conor Charles OBrien
Publisher: name: University of British Columbia
Year: 2010

description: Emissions from on-road transportation sources are a complex mixture of gaseous and particulate pollutants. Particulate matter (PM) emissions are especially important because – although short lived in the atmosphere – they are strongly associated with cardiovascular and respiratory disease and are strong climate forcing agents. The overall objective of this research was to quantify the effectiveness of emission control policies for in-use vehicles in India. I have focused on understanding the impacts of large-scale adoption of compressed natural gas (CNG) as an alternative to diesel and gasoline in New Delhi, India. In Chapter 2, I quantified the climate impacts of switching to CNG for public transportation vehicles (taxis and buses). The study showed that converting buses from diesel to CNG significantly reduced climate-warming diesel particulate matter (PM), but the increase in CH₄ emissions from all vehicle types offset much of this benefit. Chapters 3-5 focused on auto-rickshaws (three-wheeled taxis), which are an important mode of passenger transport in many developing countries. In Chapter 3, a survey of 350 drivers quantified activity patterns, fuel consumption and CO₂ emissions for auto-rickshaws, and a model was developed to better understand the determinants of visible smoke emissions. Chapter 4 describes a laboratory (chassis dynamometer) study that measured emissions from 31 auto-rickshaws, and establishes fuel-based emission factors for gaseous and fine PM pollutants from 2-stroke and 4-stroke spark-ignited engines fueled with CNG and gasoline. Finally, Chapter 5 examines a range of emission-reduction policies for auto-rickshaws, including phasing out 2-stroke engines, switching to CNG fuel, scrapping older vehicles and four different types of inspection and maintenance (I/M) programs. Together, these studies demonstrate that certain fuel/engine combinations, such as CNG-fueled 4-stroke engines, are more robust low-emitters than others, and can be an effective alternative to diesel engines (in buses) or 2-stroke engines (in auto-rickshaws). Although this research has examined emissions-reduction policy in New Delhi, the findings are applicable to in-use vehicles in many other jurisdictions in the developing world.

description: Accurate knowledge for hydrate formation conditions of pure propane in the presence of liquid water is important to avoid flow assurance issues in processing, storage and transportation of liquefied petroleum gas, as well as modeling hydrate based separation processes involving type II hydrates. Experimental dissociation conditions were measured using the phase boundary dissociation method, which has the advantages of reduced experimental time and generation of more equilibrium dissociation data when compared to other hydrate measurement techniques. In this study, phase equilibra measurements are reported for 99.5 mol % and 99.999 mol % propane at the phase boundary for the liquid water (Lw)-hydrate (H)-propane vapour (C3H8 (g)) and Lw -H-liquid propane (C3H8 (l)) loci. The results were modeled using van der Waal and Platteeuw model for the hydrate phase and reduced Helmholtz energy equation for the fluid phases. Results are compared with highly variant literature data, where large deviations observed for the Lw-H-C3H8 (l) phase boundary can be mainly attributed to purity and experimental techniques used in the literature.

description: In the framework of a field theoretic model obtained by second quantization of Doi-type master equation, we investigate the effects of random sources and sinks on the reaction kinetics in the master-equation description. We show that random sources and sinks significantly affect the asymptotic behavior of the model and identify two universality classes when describing them using scaling analysis. We compare the results with the Langevin-equation description of the same process.

Stratigraphy and Geochemistry of Lower Permian volcanics in the Sverdrup Basin, Northwest Ellesmere Island, Nunavut
Creators: name: Morris, Natasha
Publisher: name: Graduate Studies
Year: 2013
Subjects: Sciences

description: Five sections of Lower Permian mafic volcanics were examined on northwest Ellesmere Island in the Sverdrup Basin, Arctic Canada. Detailed field work shows that two stratigraphic levels exist; the lower level is an unnamed volcanic unit that occurs in a Sakmarian-Artinskian succession, and the upper level is a mappable unit, the Esayoo Formation, which occurs in a Kungurian succession. Within the regional upper Paleozoic sequence stratigraphy the volcanics are contemporaneous with transgressive systems tracts. Petrographically, these volcanics are spilites. Trace element chemistry illustrates patterns similar to ocean island basalts. Tectonic discriminant diagrams show affinities to within plate basalts, with alkaline to transitional basalt affinities. Sm-Nd isotopic analyses suggest the Esayoo Formation is sourced from an enriched mantle, with values that range from -3.99 to -5.87. Trace element ratios reveal an enriched mantle type I (EMI) source. In addition these volcanic occurences are synchronous with coeval compressional-extensional tectonic pulses associated with the Melvillian Disturbance.

description: Rapid variability in the radio flux density of the BL Lac object PKSB1144-379 has been observed at four frequencies, ranging from 1.5 to 15 GHz, with the VLA and the University of Tasmania's Ceduna antenna. Intrinsic and line of sight effects were examined as possible causes of this variability, with interstellar scintillation best explaining the frequency dependence of the variability timescales and modulation indices. This scintillation is consistent with a compact source 20-40 microarcseconds, or 0.15-0.3 pc in size. The inferred brightness temperature for PKSB1144-379 (assuming that the observed variations are due to scintillation) is 6.2e12 K at 4.9 GHz, with approximately 10 percent of the total flux in the scintillating component. We show that scintillation surveys aimed at identifying variability timescales of days to weeks are an effective way to identify the AGN with the highest brightness temperatures.

Metamorphic and Tectonic Evolution of the Paleoproterozoic Thompson Nickel Belt, Manitoba

description: The Thompson Nickel Belt occurs along the northwestern margin of the Superior craton which was tectonically reworked during the Paleoproterozoic Trans-Hudson orogeny. This work represents the first comprehensive regional metamorphic study of the belt. Three nested metamorphic domains are present in the Thompson Nickel Belt which are elongate subparallel to the regional strike of the belt. The metamorphic domains consist of a central middle amphibolite-facies zone enclosed by an upper amphibolite-facies zone. The upper amphibolite-facies zone is flanked to the northwest and southeast by granulite-facies zones. The dominant phase of penetrative deformation was responsible for the development of regional isoclinal to recumbent folds accompanied by a regionally penetrative foliation. The analysis of microstructures suggests peak metamorphism was coincident with and possibly outlasted this penetrative event. Later generations of deformation resulted in tight, vertical to steeply incline folds commonly paralleled by shear zones with subvertical stretching lineations. Shear zones and fabrics generated by the later deformation events are commonly characterized by retrograde greenschist-facies mineral assemblages. The later generations of structures appear to exert a first order control on the present day distribution of metamorphic zones within the belt. The regional metamorphism was characterized by relatively low pressures. Peak temperature and pressure conditions were estimated to be 550–620 °C and 3.0–5.0 kbar in the middle amphibolite-facies zone, 675–755 °C and 4.5–6.0 kbar in the upper amphibolite-facies zone, and 775–830 °C and 5.0–7.0 kbar in the granulite-facies zone. Closely spaced regional metamorphic isograds indicate locally steep geothermal gradients. Metamorphic pressure–temperature paths are interpreted to be broadly clockwise. Collision between the Thompson Nickel Belt and the adjacent terranes of the Trans-Hudson Orogen was initiated ca. 1850 Ma. Progressive tectonic burial, accompanied by prograde metamorphism continued beyond ca. 1776 Ma. Peak metamorphic conditions were likely attained diachronously between the various metamorphic-facies zones; however, it appears to have been concurrent with, or outlasted, the dominant generation of penetrative deformation. Metamorphism was broadly synchronous with granitoid magmatism from ca. 1850 to 1750 Ma, which may have contributed to the low pressure–high temperature metamorphism characteristic of the TNB.

description: Suicidal behavior is a leading cause of injury and death worldwide. Suicide has been associated with psychiatric illnesses such as depression and schizophrenia, as well as economic uncertainty, and social/cultural factors. This study proposes a neuroeconomic framework of suicide. Neuroeconomic parameters (e.g., risk-attitude, probability weighting, time discounting in intertemporal choice, and loss aversion) are predicted to be related to suicidal behavior. Neurobiological and neuroendocrinological substrates such as serotonin, dopamine, cortisol (HPA axis), nitric oxide, serum cholesterol, epinephrine, norepinephrine, gonadal hormones (e.g., estradiol and progesterone), dehydroepiandrosterone (DHEA) in brain regions such as the orbitofrontal/dorsolateral prefrontal cortex and limbic regions (e.g., the amygdala) may supposedly be related to the neuroeconomic parameters modulating the risk of suicide. The present framework puts foundations for "molecular neuroeconomics" of decision-making processes underlying suicidal behavior.

description: Parasites are important components of ecosystems; significantly impacting host health, and informing on contemporary and historical host movements and environmental changes. I characterised gastrointestinal parasite faunas and assessed their associations to body condition and fecundity in two populations of west Greenland caribou (Rangifer tarandus groenlandicus). Parasite diversity was described using fecal flotations and examinations of abomasa and small intestines. Anoplocephalidae, Nematodirinae and “Strongyle”-type eggs and Eimeria oocysts were found in fecal samples from both populations, but Marshallagia spp. eggs were only found in those from Kangerlussuaq-Sisimiut. Adult nematodes were recovered from all abomasa, with Marshallagia marshalli and Teladorsagia boreoarcticus from Kangerlussuaq- Sisimiut and Ostertagia gruehneri from Akia-Maniitsoq caribou. I hypothesise these faunas were structured by parasite loss during caribou colonization and subsequent parasite spill-over from introduced muskoxen and reindeer. Body condition of caribou from both populations was negatively associated with adult nematode intensity; however, fecundity was only associated with O. gruehneri.
The influence of volunteer communication networks on identification and engagement

description: Many nonprofit organizations relying on a voluntary workforce encounter challenges as volunteering rates have been continually decreasing and the patterns of volunteering have been changing. For practitioners, it is critical to understand how to attract such volunteers to be more engaged, and for the communication scholar, we should pay more attention to nonprofit organizations and communicative properties of volunteer memberships (Lewis, 2005). Although previous literature committed to understanding this phenomenon by investigating predictors of volunteer behavior and causes for the turnover intentions, absent from the scholarship is a discussion of communicative approaches to identity and identification, and of how volunteers’ communication networks could affect volunteerism. This dissertation took a communicative approach to understanding this phenomenon by focusing on the processes of constructing and reconstructing identities and identification with multiple targets in social contexts. Further, this study examined how volunteer communication networks affect their communicative and general engagement in volunteering. The findings from both quantitative and qualitative analyses of the data highlighted the active and communicative processes of identification with the collectives in situated contexts, and the targets of identification among volunteers not bounded by organizational boundaries, and its positive influence on general as well as communicative engagement in volunteering. The results on communication networks also suggested the positive impacts of volunteers’ information provision networks, the size of volunteering affiliated networks, and having variation in age among interactants on volunteers’ communicative and general engagement in volunteering. This dissertation also offered some practical as well as theoretical implications to the current literature.

description: We introduce a systematic framework to calculate the bipartite entanglement entropy of a compact spatial subsystem in a one-dimensional quantum gas which can be mapped into a noninteracting fermion system. We show that when working with a finite number of particles N, the Renyi entanglement entropies grow as log N, with a prefactor that is given by the central charge. We apply this novel technique to the ground state and to excited states of periodic systems. We also consider systems with boundaries. We derive universal formulas for the leading behavior and for subleading corrections to the scaling. The universality of the results allows us to make predictions for the finite-size scaling forms of the corrections to the scaling.

description: Ih is a hyperpolarization-activated current that is widely distributed in the brain and which contributes to various physiological processes. HCN channels that give rise to Ih are an important target of cellular signals that regulate neuronal responses to external stimuli. In this thesis, I characterize the HCN channel-associated signaling complex and its impact on hippocampal function at molecular and cellular levels. Using whole cell-current recordings in hippocampal primary cultures prepared from wild-type (WT) and cellular prion protein (PrPC) knockout (KO) mouse pups, I found that the absence of PrPC profoundly affected the firing properties of cultured hippocampal neurons. These included an increased number of action potentials (APs) and a decreased spike threshold. By performing whole cell-voltage recordings, a reduced ionic current Ih was observed in KO neurons as indicated by a decreased voltage sag, a hyperpolarizing shift in activation gating and an enhanced input resistance. However, co-IP results did not reveal a molecular complex formed between HCN and PrPC. These results indicate that HCN channels are functionally but not physically associated with PrPC to regulate hippocampal neuronal excitability. Further dissecting on HCN channel-associated signaling in tsA-201 cells revealed that HCN1 and Cav3.2 channels can be associated in a physical complex. The coexpression of HCN1 channels altered the functional properties of Cav3.2 currents, including a reduced Cav3.2 current density, altered channel kinetics and a depolarizing shift in activation gating. Mutual interaction regions in both channels were also determined. Overall, these findings identify HCN channel-associated signaling at molecular and functional levels, including functional interactions between HCN channels and PrPC, and physical interactions between HCN1 and Cav3.2 channels. This study provides a framework for understanding the HCN channel-associated interactions in the context of neuronal excitability.

description: Mesenchymal stem cells (MSCs) exert their effects in part by limiting oxidative stress. Of therapeutic interest are the effects of MSCs in obesity, a cause of elevated reactive oxygen species (ROS). ROS are particularly deleterious as they are associated with decreased insulin sensitivity and low-grade inflammation. The current study analyzed the antioxidant activity of MSCs in the dietary-induced obese C57BL/6 model. The hypothesis was that MSCs would modulate increases in ROS production associated with dietary-induced obesity. Acute treatment of obese, insulin resistant animals normalised hepatic oxidative stress. Interestingly, MSC-treatment had no effect on insulin resistance, glucose tolerance and low-grade inflammation – conditions associated with ROS. The current study is the first to ascertain the potential use of MSCs to curb diet induced oxidative stress. Results provoke further exploration into the specific mechanisms by which MSCs reduce ROS in insulin resistant pathology.
Organizing attention: caring for Japanese popular culture in the new political economy
Creators: name: Hsieh, Yu-I
Publisher: name: No Publisher Supplied
Year: 2020

description: Organizing Attention is both a critical inquiry into the configurations of the Japanese popular culture of anime and manga in relation to Japan’s social economy, and a theoretical consideration of how cultural industries and hyperindustrial technologies of consumer capitalism mutate attention formation. The existing literature in the bourgeoning field of anime and manga studies has largely adhered to the approaches of media studies and cultural studies, with both strands developing formal analyses on a premise that media is a carrier of content tethered to the imaginary topos of Japanese culture. Drawing on theories offered by Bernard Stiegler, I propose a paradigm shift by highlighting attention-capture capacities of media as artifacts in making, remaking or unmaking a cultural milieu, irrespective of the content being represented. Beginning with the instance of the attempted censorship of explicit anime, I argue against the grain that efforts to institute parental controls bespeak a structural carelessness by delegating care for youth to technologies and entertainment industries. What is at stake is that attention-capturing technologies of the entertainment and advertising industries short-circuit attention and desire by subjecting the mind to the incessant stimulation of consumption. On the macro level, anime and manga’s emerging as the forerunner of Japan’s global soft power since the 1990s is part of the larger shift from biopower to what Stiegler calls “psychopower,” where the mind, formed by ways of organizing attention, becomes the site of governmentality. My project assembles analyses on different articulations of Japanese popular culture, from Japan’s self-Orientalizing discourse in the 1990s, canonical anime such as Ghost in the Shell and Neon Genesis Evangelion, to the most recent virtual waifu phenomenon. I demonstrate how anime and manga as forms of psychopower constellate geopolitics, social psyche and libidinal economy. Specifically, otaku, the moniker for “maniac” fans, epitomizes the issues in Japan’s consumerist-driven ideology after WWII and its neoliberal turn in the new millennium. By showing how otaku play, I conclude my study by emphasizing that the potentials of technologies are entangled with the way we organize attention.
Notation for an Electric Stage: Twenty Years of Writing about Notation and a Thought Experiment. With additional commentary about Preservation

description: This paper is a sprawling document covering practical issues about music notation with more theoretical implications of notation. A distinction between reperformance and preservation is elucidated, and a thought experiment of how to notate a time-based light sculpture (László Moholy-Nagy’s Light Prop for an Electric Stage) encourages readers to think about notation as removed from sonic content. It is vital for composers to create notation that goes beyond the notes, so that pieces involving media can be re-performed in addition to creating an informed archive of the initial state(s) of the work as mediated by the composer themselves.

description: This thesis presents an overview of modifications made to an existing shock tube facility that will facilitate future studies involving hydrogen and nano-particle combustion. The modifications were made to the shock tube located in the University of Calgary’s High Speed Aerodynamics and Energy Research Laboratory. Specific changes were made to the driver section utilizing shock tube tailoring with the aim of increasing available test times from 3 ms to 10 ms at 900 K end wall temperatures. A novel method of determining the local gas mixture based on measured shock velocity and shock tube pressure data was also developed and tested with mixtures of nitrogen and helium. Results of these tests show that that the method used in this study can estimate the mole fraction of helium within 4% of the expected value.
Overview on spectral line source finding and visualisation

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: Here I will outline successes and challenges for finding spectral line sources in large data cubes that are dominated by noise. This is a 3D challenge as the sources we wish to catalog are spread over several spatial pixels and spectral channels. While 2D searches can be applied, e.g., channel by channel, optimal searches take into account the 3-dimensional nature of the sources. In this overview I will focus on HI 21-cm spectral line source detection in extragalactic surveys, in particular HIPASS, the "HI Parkes All-Sky Survey" and WALLABY, the "ASKAP HI All-Sky Survey". I use the original HIPASS data to highlight the diversity of spectral signatures of galaxies and gaseous clouds, both in emission and absorption. Among others, I report the discovery of a 680 km/s wide HI absorption trough in the megamaser galaxy NGC 5793. Issues such as source confusion and baseline ripples, typically encountered in single-dish HI surveys, are much reduced in interferometric HI surveys. Several large HI emission and absorption surveys are planned for the Australian Square Kilometre Array Pathfinder (ASKAP): here we focus on WALLABY, the 21-cm survey of the sky (Dec < +30 degr; z < 0.26) which will take about one year of observing time with ASKAP. Novel phased array feeds ("radio cameras") will provide 30 square degrees instantaneous field-of-view. WALLABY is expected to detect more than 500 000 galaxies, unveil their large-scale structures and cosmological parameters, detect their extended, low-surface brightness disks as well as gas streams and filaments between galaxies. It is a precursor for future HI surveys with SKA Phase I and II, exploring galaxy formation and evolution. The compilation of highly reliable and complete source catalogs will require sophisticated source-finding algorithms as well as accurate source parametrisation.

Notating electronics
Creators: name: Faia, Carl
Publisher: name: Musica/Tecnologia
Year: 2019

description: While we have always had the need to represent music — ephemeral and abstract in every sense of those adjectives — a special need has been more recently, and acutely, expressed in notating electronics and electro-acoustic music. This has presented composers and copyists with a certain number of problems, including how to notate these new sounds in the context of adapting a preexisting notational system, or with a purpose designed scheme to respond to the perceived needs of the medium. After an overview of the history of notation in the context of contemporary needs, the article presents the merits of using the traditional system compared to creating new system(s). In conclusion, moving towards a different system of notation is pitched against using what we already know and use with some suggestions on moving forward towards a common practice in notating electronics. Solutions are illustrated with real-world examples taken from collaborative projects with composers Jonathan Harvey, James Dillon and others over the last 20 years.

The production cross section of electrons from heavy-flavour hadron decays is measured in pp collisions at $\sqrt{s}$=7 TeV. Electrons from the beauty decays are identified via the displacement from the interaction vertex. From the electron spectra measured in Pb--Pb collisions, we determine the nuclear modification factor, which is sensitive to the heavy-quark energy loss in a hot strongly interacting medium.

Thus, large projects are monitored unsystematically by collecting limited onsite data, restricting the project management team to identify delays, and rework on time. The correct determination of the project’s performance also relies heavily on the correctness and completeness of the collected data during the monitoring process. Hence, site supervisory personnel spend considerable time just to manually control the quality of the manually collected onsite data. Several research studies have aimed to use remote sensing technologies such as LiDAR and cameras to acquire 3D point clouds of building elements to improve the quality of the collected data; however, these studies assume the planned BIM as a priori knowledge to assign the point clouds to their corresponding structural element, which provide inaccurate basis for reporting the as-built status of a project, especially when the planned and the actual differ or the planned model is not available with sufficient detail. Here, using the most up-to-date pattern recognition, robust statistical analysis and mathematical modelling techniques, a new robust approach was formulated, independent from a pre-existing planned model, to automatically generate the as-built model of common structural elements with predominantly planar and linear surfaces directly from the acquired point cloud. In the context of four experiments, ten sets of point clouds, nine from actual construction sites, were collected to express, verify and validate the diverse applicability of the proposed system for automated progress monitoring, structural displacement analysis, and dimensional conformation control. It was demonstrated that the novel robust planar and linear point cloud classification and segmentation method, presented here, achieved an overall accuracy of better than 90.4% for all datasets, indicating its generic applicability for construction projects. It was also shown that the proposed system is capable of automatically generating as-built models of common structural elements with the 3-5mm desired construction grade accuracy.

description: In this interview with Marco Angius, the music conductor was asked about the role of technology in musical performances, the problems in the use of technological media and the evolution of his artistic-professional trajectory in electro-acoustic musical productions. Mr. Angius offers insight into a number of topics that stem from his interaction with technology, the splitting of the “sign” from sound and the resulting notational and interpretational problems. He also focuses on his work during the re-performance of Prometeo. Tragedia dell’ascolto by Luigi Nono in Parma in 2017. His thoughts come from a privileged point of view, the person who has at the same time the highest “control” over score and performers, and who embodies the medium between the latter and the electronic instruments.

Musica elettronica e scrittura: appunti di un editore

description: Electroacoustic music with its technological nature dictates a rethinking of traditional categories in music publishing. Concepts such as “work”, “author”, “instrument”, “performer”, even the very idea of “writing”, all change and must be reconsidered alongside the medium, the carrier. The work I’ve being doing as a music publisher puts me in the position to choose among different solutions, in the attempt to reproduce and guarantee this interesting complexity. On the other hand, I also intend to introduce an order in this complexity, with the aim to salvage every single process of development, protection and valorisation of the works we are publishing. In my article I focus on the principles I’m following in my work, not so much to “domesticate” musical ideas into a fixed standard, but to free every work from its particularism – especially from the dependence from technological devices and specific human agents (performers, collaborators). In the last part I discuss the work we are doing to publish a new, more efficient score of Prometeo. Tragedia dell’ascolto (1981-1985) by Luigi Nono.

description: Objectives: Stress hormones have been associated with temporal discounting. Although time-discount rate is shown to be stable over a long term, no study to date examines whether individual differences in stress hormones could predict individuals' time-discount rates in the relatively distant future (e.g., six month later), which is of interest in neuroeconomics of stress-addiction association. Methods: We assessed 87 participants' salivary stress hormone (cortisol, cortisone, and alpha-amylase) levels and hyperbolic discounting of delayed rewards consisting of three magnitudes, at the time-interval of six months. For salivary steroid assays, we employed a liquid chromatography/ mass spectroscopy (LC/MS) method. The correlations between the stress hormone levels and time-discount rates were examined. Results: We observed that salivary alpha-amylase (sAA) levels were negatively associated with time-discount rates in never-smokers. Notably, salivary levels of stress steroids (i.e., cortisol and cortisone) negatively and positively related to time-discount rates in men and women, respectively, in never-smokers. Ever-smokers' discount rates were not predicted from these stress hormone levels. Conclusions: Individual differences in stress hormone levels predict impulsivity in temporal discounting in the future. There are sex differences in the effect of stress steroids on temporal discounting; while there was no sex defference in the relationship between sAA and temporal discounting.

description: Real-time/performed electroacoustic music is currently facing a serious sustainability problem. Although historically its production is very recent, several technological revolutions have gone by in the meantime. Most of these works can hardly be performed because the technology involved has gone lost since the first realization, and no long-standing notational precaution was ever taken. This paper (first published in 2005 and translated in Italian for the first time) presents some typical case studies and introduces some techniques that might lead to a partial — when not completely adequate — solution to the sustainability problem.

Latitudinal gradients in adaptive traits of Populus

description: In an attempt to better understand adaptation to north-temperate and boreal environments, I have studied variation in phenology, ecophysiology and single nucleotide polymorphisms in an extensive range-wide collection of Populus balsamifera L. (balsam poplar) populations. Based on three years of observation, I infer that the differences in phenology between two common garden sites, with similar photoperiodic regimes but dramatically different climates, is based on differences in spring start date resulting in different dates of photoperiodic competency for height growth cessation and leaf senescence. Autumn phenophases in balsam poplar are primarily cued by the absolute photoperiod and do not respond to direction of change or climate warming. Interactions between photoperiod, climate and genotype can have large, heretofore unreported effects on root:shoot ratio. By comparison to P. tremula L. (European aspen) and published data for P. trichocarpa Torr. & Gray (black cottonwood), I found, in common garden conditions, a global tendency towards increasing photosynthetic rates with latitude. Height growth, being under photoperiodic control, follows the opposite pattern. When photoperiodic limitations were removed in a greenhouse experiment, higher photosynthesis in high latitude genotypes of balsam poplar was associated with greater height increment. Mesophyll conductance also varied clinally and accounts, in part, for higher photosynthesis in the northern balsam poplar genotypes. Phenotypic data presented in this thesis will ultimately be used for large-scale association genetics in the hopes of identifying candidate genes controlling adaptation to growing season length. As a step in this direction, we examined the comparative nucleotide diversity of the three above Populus species. We confirm that the closely related North American species (i.e., both within the section Tacamahaca) have lower nucleotide diversity than the more distantly related European aspen (section Populus). Divergence between the sections is estimated at about five million years ago, whereas P. balsamifera and P. trichocarpa diverged more recently (~0.8 million years ago). Linkage disequilibrium in balsam poplar decayed rapidly (within 400 bp).
Confronting Seiberg's Duality with r Duality in N=1 Supersymmetric QCD

description: Systematizing our results on r duality obtained previously we focus on comparing r duality with the generalized Seiberg duality in the r vacua of N=2 and N=1 super-Yang-Mills theories with the U(N) gauge group and N_f matter flavors (N_f>N). The number of condensed (s)quarks r is assumed to be in the interval 2N_f/3 < r \le N. To pass to N=1 we introduce an N=2-breaking deformation, a mass term μfor the adjoint matter, eventually decoupling the adjoint matter in the limit of large μ. If one starts from a large value of the parameter ξ\simμm, where the original theory is at weak coupling, and decreases ξone hits a a crossover transition from weak to strong coupling (here m is a typical value of the quark masses). Below this transition the original theory is described in terms of a weakly coupled infrared-free r dual theory with the U(N_f-r) gauge group and N_f light quark-like dyon flavors. Dyon condensation leads to confinement of monopoles, defying a naive expectation of quark confinement. The quarks and gauge bosons of the original theory are in an "instead-of-confinement" phase. The r and Seiberg dualities are demonstrated to coincide in the r=N vacua. In the (2/3) N_f

description: Atomic Force Microscopy (AFM) is a versatile method for nanoscale measurement of the properties of materials. While many methods have been developed to utilize AFM for nanoscale characterization of stiffness, damping characterization has remained less explored. In this research, we present a method for measuring stiffness and damping using Contact Resonance Atomic Force Microscopy (CR-AFM) and Modal Finite Element Analysis (FEA). To do so we compare resonance peaks and quality factors obtained from FEA and CR-AFM and we adjust the parameters until there are in good agreement. We use this method to measure the stiffness and damping of several polymers.
