description: Aims: Our aim is to understand the evolutionary sequence of high-mass star formation from the earliest evolutionary stage of high-mass starless cores, via high-mass cores with embedded low- to intermediate-mass objects, to finally high-mass protostellar objects. Methods: Herschel far-infrared PACS and SPIRE observations are combined with existing data at longer and shorter wavelengths to characterize the spectral and physical evolution of massive star-forming regions. Results: The new Herschel images spectacularly show the evolution of the youngest and cold high-mass star-forming regions from mid-infrared shadows on the Wien-side of the spectral energy distribution (SED), via structures almost lost in the background emission around 100mum, to strong emission sources at the Rayleigh-Jeans tail. Fits of the SEDs for four exemplary regions covering evolutionary stages from high-mass starless cores to high-mass protostellar objects reveal that the youngest regions can be fitted by single-component black-bodies with temperatures on the order of 17K. More evolved regions show mid-infrared excess emission from an additional warmer component, which however barely contributes to the total luminosities for the youngest regions. Exceptionally low values of the ratio between bolometric and submm luminosity additionally support the youth of the infrared-dark sources. Conclusions: The Herschel observations reveal the spectral and physical properties of young high-mass star-forming regions in detail. The data clearly outline the evolutionary sequence in the images and SEDs. Future work on larger samples as well as incorporating full radiative transfer calculations will characterize the physical nature at the onset of massive star formation in even more depth.

description: We study the importance of inter-site coherences and quantum interference effects in the x-ray absorption spectroscopy (XAS) of mixed-valent systems. We demonstrate its importance, first for a simple diatomic mixed-valent molecule to elucidate the physics involved, and finally for mixed-valent Ti oxides, using a model calculation including full spin and orbital multiplicities. Our calculations demonstrate the inefficacy of conventional approaches of describing the XAS from mixed-valent systems as incoherent combinations of XAS from the pure-valent end members, and that multiplets forbidden in the single-site approximation can be reached within a multi-site description. These conclusions play an important role in the interpretation of XAS and resonant x-ray scattering (RXS) in terms of the electronic structure of strongly correlated systems.

description: The Mesa Central (MC) of Mexico presents a noticeable feature as is the three-dimensional (3D) deformation of Cenozoic volcanic rocks. To figure out when this unusual deformation began, we constructed a geological map at 1:100,000 scale, with detailed stratigraphy, and thirteen new U-Pb ages in the southern MC. The mapped area is dominated by silicic volcanic rocks with ages from ca. 34.4 Ma to ca. 23.5 Ma affected by coeval normal faulting. An angular unconformity evidences a shift in the deformation style that occurred around 30 Ma, from an NW-trending fault system in domino-style to a polymodal fault system, which also temporally coincided with the emplacement of lava dome complexes. The structural and stratigraphic data give new insight for understanding how the polymodal fault system developed in the southern MC, suggesting that the change in the deformation and volcanism regime played an important role.

description: We investigate the formation of bow shocks around exoplanets as a result of the interaction of the planet with the coronal material of the host star, focusing on physical causes that can lead to temporal variations in the shock characteristics. We recently suggested that WASP-12b may host a bow shock around its magnetosphere, similarly to the one observed around the Earth. For WASP12b, the shock is detected in the near-UV transit light curve. Observational follow-up suggests that the near-UV light curve presents temporal variations, which may indicate that the stand-off distance between the shock and the planet is varying. This implies that the size of the planet's magnetosphere is adjusting itself in response to variations in the surrounding ambient medium. We investigate possible causes of shock variations for the known eccentric (e>0.3) transiting planets. We show that, because the distance from the star changes along the orbit of an eccentric planet, the shock characteristics are modulated by orbital phase. We predict time offsets between the beginnings of the near-UV and optical light curves that are, in general, less than the transit duration. Variations in shock characteristics caused in eccentric systems can only be probed if the shock is observed at different orbital phases, which is, in general, not the case for transit observations. However, non-thermal radio emission produced by the interaction of the star and planet should be modulated by orbital phase. We also quantify the response of the shock to variations in the coronal material itself due to, e.g., a non-axisymmetric stellar corona, planetary obliquity, intrinsic variations of the stellar magnetic field. Such variations do not depend on the system eccentricity. We conclude that, for systems where a shock is detectable through transit light curve observations, shock variations should be a common occurrence. (Abridged)

Impact of antimicrobial treatments on sprouting alfalfa seed contaminated with Salmonella enterica
Creators: name: Dai, Yue
Publisher: name: University of British Columbia

description: Consumption of alfalfa sprouts has increased worldwide due to the nutritional value and health benefits of sprouts. However, alfalfa sprouts contaminated with Salmonella enterica (S. enterica) have been the source of many foodborne outbreaks in Europe and North America. Antimicrobial treatments for sprouted seeds are recommended by the Canadian Food Inspection Agency but the influence of different antimicrobial sanitation seed treatments on the behaviour of S. enterica during seed germination remains unclear. The goals of this study were (1) to investigate the ability of S. enterica to grow on sprouting alfalfa seeds after three different sanitation seed treatments to reduce microbial load, and (2) to understand how colonization by S. enterica and different antimicrobial treatments affect metabolites released by sprouting alfalfa seed. Alfalfa seeds inoculated with five strains of S. enterica were subject to three different seed treatments: (1) sodium hypochlorite (NaClO), (2) hydrogen peroxide (H₂O₂), and (3) an organic treatment involving a hot water dip, treatment with H₂O₂ and acetic acid. The disinfected seeds were sprouted to identify the growth characteristics of S. enterica after sanitation stress (n = 3). The populations of all five S. enterica strains which were present at <10 CFU/g immediately after sanitation treatment increased to 4 - 8 log CFU/g after 6 days of germination. After 6 days of germination, most S. enterica strains recovered from sprouts germinated from seeds treated with H₂O₂ or the organic treatment were lower than those recovered from sprouts germinated from seeds treated with NaClO. Additionally, metabolites were identified by rinsing seeds after 24 hours of germination (n = 4). Almost all of the 535 identified compounds were affected by the application of antimicrobial treatments. Specifically, the NaClO treatment diminished the levels of metabolites on uninoculated, S. enterica Agona and Typhimurium colonized sprouting seed by almost half, possibly via oxidative destruction. The organic treatment increased and decreased similar numbers of metabolites, around 30% of all detected metabolites. This study provided new insight on the ecology of S. enterica on germinating seeds, an important consideration in the development of better strategies to lessen the risk associated with sprouted vegetables.

description: We show analytically and numerically that the appearance of lumps and gaps in the distribution of n competing species along a niche axis is a robust phenomenon whenever the finiteness of the niche space is taken into account. In this case depending if the niche width of the species $σ$ is above or below a threshold $σ_c$, which for large n coincides with 2/n, there are two different regimes. For $σ> sigma_c$ the lumpy pattern emerges directly from the dominant eigenvector of the competition matrix because its corresponding eigenvalue becomes negative. For $σ- sigma_c$ the lumpy pattern disappears. Furthermore, this clumping transition exhibits critical slowing down as $σ$ is approached from above. We also find that the number of lumps of species vs. $σ$ displays a stair-step structure. The positions of these steps are distributed according to a power-law. It is thus straightforward to predict the number of groups that can be packed along a niche axis and it coincides with field measurements for a wide range of the model parameters.

description: Factorization of quantum mechanical potentials has a long history extending back to the earliest days of the subject. In the present paper, the non-uniqueness of the factorization is exploited to derive new isospectral non-singular potentials. Many one-parameter families of potentials can be generated from known potentials using a factorization that involves superpotentials defined in terms of excited states of a potential. For these cases an operator representation is available. If ladder operators are known for the original potential, then a straightforward procedure exists for defining such operators for its isospectral partners. The generality of the method is illustrated with a number of examples which may have many possible applications in atomic and molecular physics.

description: The Las Minas area corresponds to an exhumed geothermal system considered a proxy for the deep part of the nearby Los Humeros active geothermal system. The stratigraphic succession is made up of: Palaeozoic-Miocene granitoids, a thick Jurassic- Cretaceous carbonate succession, Neogene lava flows and volcano-sedimentary deposits. Linked to a Miocene magma intrusion, marble and skarn rock-volumes developed by contact metamorphism and geothermal fluid flow. Faults are arranged in SW- and NNW-striking systems. These controlled the morphological evolution and favored Neogene-Quaternary dyke emplacement. Faulting gave rise to a tectonic depression where lacustrine sediments and pyroclastics deposited. Skarn rocks are mainly located at fault intersections and along pre-existing discontinuities, suggesting the role of bedding and/or fractures in channeling deep fluids. Results give inputs for exploration at depth of Los Humeros geothermal system.

description: We consider the finite temperature Casimir force acting on two parallel plates in a closed cylinder with the same cross section of arbitrary shape in the presence of extra dimensions. Dirichlet boundary conditions are imposed on one plate and fractional Neumann conditions with order between zero (Dirichlet) and one (Neumann) are imposed on the other plate. Formulas for the Casimir force show that it is always attractive for Dirichlet boundary conditions, and is always repulsive when the fractional order is larger than 1/2. For some fractional orders less than 1/2, the Casimir force can be either attractive or repulsive depending on the size of the internal manifold and temperature.

R CrA SMM1A: Fragmentation in A Prestellar Core

Year: 2010

description: We report the discovery of multiple condensations in the prestellar core candidate SMM1A in the R~CrA cloud, which may represent the earliest phase of core fragmentation observed thus far. The separation between the condensations is between 1000 and 2100 AU, and their masses range from about 0.1 to 0.2 M_sun. We find that the three condensations have extremely low bolometric luminosities (< 0.1 L_sun) and temperatures (< 20 K), indicating that these are young sources that have yet to form protostars. We suggest that these sources were formed through the fragmentation of an elongated prestellar core. Our results, in concert with other observed protostellar binary systems with separations in the scale of 1000 AU, support the scenario that prompt fragmentation in the isothermal collapse phase is an efficient mechanism for wide binary star formation, while the fragmentation in the subsequent adiabatic phase may be an additional mechanism for close (< 100 AU) binary star formation.

Bond analysis of fibre reinforced polymer (FRP) rods and timber beams
Creators: name: Walline, Devin Rodney
Publisher: name: University of British Columbia
Year: 2018

description: The use of timber in structures has been common for thousands of years, however, in the last century timber has been losing a significant market share to other construction materials such as concrete and steel due to their superior load carrying capabilities. In order for timber to be widely utilized as a structural material, a solution needs to be found which will provide increased structural capacity and could potentially act as a strengthening or repair method in the event of building code changes or damage. One potentially attractive solution is to incorporate high strength fibre reinforced polymer (FRP) rods as a reinforcement similar to that of steel in reinforced concrete. This can be completed through the application of near surface mounted (NSM) FRP rods along the soffit of the beam to act as a flexural reinforcement. For this strengthening method to be feasible, the behaviour of the bond between the FRP rod and timber material must be understood to prevent bond failure which is sudden and brittle. This study was conducted to determine the impacts of different variables on the bond behaviour between FRP rods and timber beams. The studied variables included loading type, FRP material, rod diameter, notch size, and bonded length. In total 93 specimens (75 flexural and 18 double shear) were prepared and tested with important performance measures being recorded, including load at failure, failure mode, load-slip relationship, and strain distribution. Results showed that FRP material, rod diameter, and bonded length were all statistically significant variables when considering the bond stress. From these results, linear regressions were conducted to quantify the relationships and determine a required development length in order to reach the ultimate load in the FRP rod given a specific loading condition. In addition, it was found that loading the FRP rods in an axial manner resulted in a relative increase in bond of between 5.4 and 13.3 depending on rod diameter and bonded length.

description: We present a 130 km2 wide geological map for the NE side of the fault-bounded High Agri Valley Southern Italy, that formed in the Quaternary in response to extensional tectonics dissecting the folds and thrusts of the Lucanian Apennine. To prepare the map, at 1:25,000 scale, we integrated information obtained through field surveys and the review of pre-existing geological data. Our work describes a number of significant map-scale structures, which can be related to well-constrained tectonic episodes. The new geological map provides important constraints that can be used to distinguish ancient structures from those that were active during the Quaternary, allowing a more detailed reconstruction of the processes that operate during the development of a post-orogenic trough. We expect that the new map will be used for different types of geological investigations, including studies of inversion tectonics, active tectonics, geosite mapping, 3D modelling of geological structures.
0316 Almada Negreiros and Le Corbusier. Parallel Methodologies and Critical Reception
Creators: name: Palmeirim, Simão
Publisher: name: RIHA Journal
Year: 2024

description: The French-Swiss artist and architect Le Corbusier (1887–1965) created a system for architects and engineers to humanize the metric system, paving the way for a new form of architecture. The Portuguese artist José de Almada Negreiros (1893–1970) developed a multifaceted literary and artistic practice, progressively constructing a theory on the relation between art and geometry. There are parallels between these two artists in the way they devoted themselves to geometry and developed a theory with a universalistic approach that extended beyond their artistic production. Le Corbusier's international recognition has led to extensive research and dissemination of his works, whereas Almada's theoretical studies on geometry and art have only recently been the object of systematic research. Recently found documents in Almada's estate shed new light on the author's knowledge of Le Corbusier's Le Modulor, and his critical reception of such work. This paper reveals these documents and examines them in depth to identify both parallels and a structural, theoretical divergence between these authors.

description: Context. The Neel IRAM KIDs Array (NIKA) is a fully-integrated measurement system based on kinetic inductance detectors (KIDs) currently being developed for millimeter wave astronomy. In a first technical run, NIKA was successfully tested in 2009 at the Institute for Millimetric Radio Astronomy (IRAM) 30-meter telescope at Pico Veleta, Spain. This prototype consisted of a 27-42 pixel camera imaging at 150 GHz. Subsequently, an improved system has been developed and tested in October 2010 at the Pico Veleta telescope. The instrument upgrades included dual-band optics allowing simultaneous imaging at 150 GHz and 220 GHz, faster sampling electronics enabling synchronous measurement of up to 112 pixels per measurement band, improved single-pixel sensitivity, and the fabrication of a sky simulator to replicate conditions present at the telescope. Results. The new dual-band NIKA was successfully tested in October 2010, performing in-line with sky simulator predictions. Initially the sources targeted during the 2009 run were re-imaged, verifying the improved system performance. An optical NEP was then calculated to be around 2 \dot 10-16 W/Hz1/2. This improvement in comparison with the 2009 run verifies that NIKA is approaching the target sensitivity for photon-noise limited ground-based detectors. Taking advantage of the larger arrays and increased sensitivity, a number of scientifically-relevant faint and extended objects were then imaged including the Galactic Center SgrB2(FIR1), the radio galaxy Cygnus A and the NGC1068 Seyfert galaxy. These targets were all observed simultaneously in the 150 GHz and 220 GHz atmospheric windows.

description: With the increasing demands for new data and real-time services, wireless networks should support calls with different traffic characteristics and different Quality of Service (QoS)guarantees. In addition, various wireless technologies and networks exist currently that can satisfy different needs and requirements of mobile users. Since these different wireless networks act as complementary to each other in terms of their capabilities and suitability for different applications, integration of these networks will enable the mobile users to be always connected to the best available access network depending on their requirements. This integration of heterogeneous networks will, however, lead to heterogeneities in access technologies and network protocols. To meet the requirements of mobile users under this heterogeneous environment, a common infrastructure to interconnect multiple access networks will be needed. In this chapter, the design issues of a number of mobility management schemes have been presented. Each of these schemes utilizes IP-based technologies to enable efficient roaming in heterogeneous network. Efficient handoff mechanisms are essential for ensuring seamless connectivity and uninterrupted service delivery. A number of handoff schemes in a heterogeneous networking environment are also presented in this chapter.

description: Reconstructing the response of present-day ice sheets to past global climate change is important for constraining and refining the numerical models which forecast future contributions of these ice sheets to sea-level change. Mapping landforms is an essential step in reconstructing glacial histories. Here we present a new map of glacial landforms and deposits on nunataks in western Dronning Maud Land, Antarctica. Nunataks are mountains or ridges that currently protrude through the ice sheet and may provide evidence that they have been wholly or partly covered by ice, thus indicating a formerly more extensive (thicker) ice sheet. The map was produced through a combination of mapping from Worldview satellite imagery and ground validation. The sub-metre spatial resolution of the satellite imagery enabled mapping with unprecedented detail. Ten landform categories have been mapped, and the landform distributions provide evidence constraining spatial patterns of a previously thicker ice sheet.

description: Multiparticle entanglement leads to richer correlations than two-particle entanglement and gives rise to striking contradictions with local realism, inequivalent classes of entanglement, and applications such as one-way or topological quantum computing. When exposed to decohering or dissipative environments, multiparticle entanglement yields subtle dynamical features and access to new classes of states and applications. Here, using a string of trapped ions, we experimentally characterize the dynamics of entanglement of a multiparticle state under the influence of decoherence. By embedding an entangled state of four qubits in a decohering environment (via spontaneous decay), we observe a rich dynamics crossing distinctive domains: Bell-inequality violation, entanglement superactivation, bound entanglement, and full separability. We also develop new theoretical tools for characterizing entanglement in quantum states. Our techniques to control the environment can be used to enable novel quantum-computation, state-engineering, and simulation paradigms based on dissipation and decoherence.

description: The economic and trade cooperation between China and Japan has experienced nearly forty years of development and generally maintained a rising momentum. Both sides enjoy good complementarity and broad prospects for cooperation in economy and trade. The outbreak of COVID-19 has a great impact on the economic and trade cooperation between China and Japan. The industrial supply chain between China and Japan has broken down, and trade has declined significantly. To resistance the disease, China and Japan can strengthen the cooperation system and public health governance system. At the same time, it is necessary to cushion the interruption of the offline cooperation mechanism between China and Japan by innovating the business cooperation model, build a special negotiation institution for the CJK Free Trade Area, expand the scope of China-Japan economic and trade cooperation, and continue to deepen the third-party cooperation working mechanism to reduce the losses of economic and trade cooperation between the two sides.

description: Purpose: To study the effects of masked auditory feedback (MAF) on speech fluency in adults with aphasia and/or apraxia of speech (APH/AOS). We hypothesized that adults with AOS would increase speech fluency when speaking with noise. Altered auditory feedback (AAF; i.e., delayed/frequency-shifted feedback) was included as a control condition not expected to improve speech fluency.Method: Ten participants with APH/AOS and 10 neurologically healthy (NH) participants were studied under both feedback conditions. To allow examination of individual responses, we used an ABACA design. Effects were examined on syllable rate, disfluency duration, and vocal intensity.Results: Seven of 10 APH/AOS participants increased fluency with masking by increasing rate, decreasing disfluency duration, or both. In contrast, none of the NH participants increased speaking rate with MAF. In the AAF condition, only 1 APH/AOS participant increased fluency. Four APH/AOS participants and 8 NH participants slowed their rate with AAF.Conclusions: Speaking with MAF appears to increase fluency in a subset of individuals with APH/AOS, indicating that overreliance on auditory feedback monitoring may contribute to their disorder presentation. The distinction between responders and nonresponders was not linked to AOS diagnosis, so additional work is needed to develop hypotheses for candidacy and underlying control mechanisms.

description: The one-pion and two-pion production in the p(alpha, alpha prime)X reaction at an energy of E{alpha} = 4.2 GeV has been studied by simultaneous registration of the scattered alpha particles and the secondary pion or proton. The obtained results demonstrate that the inelastic alpha-particle scattering on the proton at the energy of the experiment proceeds either through excitation and decay of Delta resonance in the projectile or through excitation in the target proton of the Roper resonance, which decays mainly on a nucleon and a pion or a nucleon and a sigma meson - system of two pions in the isospin I = 0, S-wave.

Development of SnO₂/PEO nanofiber gas sensor for THC detection
Creators: name: Mehrabi, Pouria
Publisher: name: University of British Columbia
Year: 2018

description: This thesis presents the development of a metal oxide semiconductor (MOS) sensor for detection of volatile organic compounds (VOCs) which is of great importance in many applications involving either control of hazardous chemicals or noninvasive diagnosis. There are numerous methods for detection of VOCs where their efficacy is assessed by their sensitivity, selectivity, recovery time and portabily. Commercial MOS sensors are embedded in a housing, blocking the gas diffusion path and also limiting their application in the handheld VOC detectors. In this research, the sensor is fabricated based on tin dioxide (SnO₂)/ Poly Ethylene Oxide (PEO) using electrospinning. The sensitivity of the proposed sensor is further improved by calcination and gold doping. The gold doping of the composite nanofibers is achieved using sputtering, and the calcination is performed using a high temperature oven. The performance of the sensor with different doping thicknesses and different calcination temperatures is investigated to identify the optimum fabrication parameters resulting in high sensitivity. The results show that the sensing properties of the sensing layer, including response and recovery time, are significantly affected by the doping and calcination procedure. The optimum calcination temperature and duration are found to be 350°C and 4 hours, respectively. Also, the optimum thickness of the gold dopant is found to be 10 nm. The sensor with the optimum fabrication process is then embedded in a microchannel coated with several metallic and polymeric layers. The role of the channel is to enhance the selectivity of the sensor against different VOCs or mixtures. The performance of the sensor is compared against a commercial sensor. The comparison is performed for methanol and a mixture of methanol and Tetrahydrocannabinol (THC) which is the psychoactive element in cannabis. Segregation of the responses obtained for methanol and the mixture of methanol and THC is presented in a 3D feature space. It is shown that the proposed sensor outperforms the commercial sensor when it is embedded inside the channel. The proposed sensor integrated with the microchannel has a potential to be used as a breath analyzer for detection of THC in the breath.

description: We formulate a time-dependent density-matrix functional theory (TDDMFT) approach for higher-order correlation effects like biexcitons in optical processes in solids based on the reduced two-particle density-matrix formalism within the normal orbital representation. A TDDMFT version of the Schrödinger equation for biexcitons in terms of one- and two-body reduced density matrices is derived, which leads to finite biexcitonic binding energies already with an adiabatic approximation. Biexcitonic binding energies for several bulk semiconductors are calculated using a contact biexciton model.
The role of carbonate mineral dissolution in turbidity reduction in an oil sands end pit lake

Surface water turbidity from dispersed clay particles can hinder the development of aquatic ecosystems. One of the primary objectives for proposed oil sands end pit lakes is that they support ecological functions and lake-specific wildlife habitat. However, high surface water turbidity has been observed in the Base Mine Lake cap water, the first full-scale demonstration oil sands end pit lake. Our previous study showed that adjusting the solution pH through carbon dioxide addition reduced surface water turbidity in oil sands tailings. Carbonate minerals such as calcite and dolomite were also previously identified in tailings, and thus the goal of this study was to determine the effect of calcite and dolomite dissolution through carbon dioxide mediated pH reduction on turbidity and the stability of suspended clay particles. Calcite dissolution resulted in ∼99% reduction of turbidity. The suspended clay particle stability was analyzed using DLVO (Derjaguin-Landau-Verwey-Overbeek) theory with water chemistry data from this column study. An inverse correlation was observed between the amount of dolomite and the energy barrier values on day 42 of the experiment. These results suggest carbon dioxide mediated calcite dissolution changes the water chemistry and is the most promising treatment condition for the settlement of suspended tailings particles.

description: This paper describes the hydrogeological map of the western Po Plain, located in Piedmont (north-western Italy). Po plain represents a hydrogeological system of European relevance, and the Piedmont Plain is the most important groundwater reservoir of the Region. The 1:300,000 scale map was realised using previous and new data to update the knowledge of this area. The map provides information about the hydrogeological complexes and their type and degree of permeability, water table levels and depth, piezometric level fluctuation, lithostratigraphic cross-sections, thickness, and percentage of the permeable deposits between 0 and 50 m from the ground surface. All this information is essential to public administrations, stakeholders, researchers, and professionals for defining possible tools for groundwater protection and management and for planning new groundwater exploitation (i.e. municipal drinking water supplies).

description: The Santo Domingo-Salinas ranges represent a unique Natural Area in the south-central Pyrenees, and they were declarationas a Protected Landscape in 2015. Available biological and geological knowledge is extensive but lacks of information on groundwater quality. In this work we provide new hydrogeological results and integrate them with previously available hydrogeological data. To do so, we have: (i) compiled existing hydrogeological information, (ii) exhaustively developed an inventory of water points, (iii) sampled, analyzed and interpreted the hydrochemical facies detected, and (iv) developed a preliminary conceptual model for the hydrogeological functioning of the area. These information has been integrated in an map that displays the chemical analyses of the two new campaigns (Stiff diagrams), the flow rates and the three aquifer systems defined. This new information improves and synthetizes the knowledge of the hidrogeology of the Santo Domingo-Salinas ranges Protected Landscape and it will help in its future management and planning.
