This study aims to develop an electronic beam lithography processing technique with the best pattern resolution among top-down machining methods and apply it to manufacture nanoscale structures. When electron beams enter a substrate with highly dense patterns, a pattern distortion occurs due to the electron beam proximity effect caused by the scattering of electron beams reaching the pattern region under the substrate. A silicon nanomold of line width 50 nm was produced and the pattern uniformity was satisfied within the tolerance range through a proper correction of the electron beam proximity effect. In addition, a photo mask with ultra-fine patterns of diameter less than 100 nm was manufactured for use in the semiconductor exposure process using the correction method of the electron beam proximity effect and innovative methods involving liftoff processes.

In this paper, a new effect of pitch proximity is reported. Subjects were presented with patterns consisting of octave-related complexes. Each pattern was composed of four tones, which constituted two simultaneous melodic lines, one of which ascended by a semitone while the other descended by a semitone. The subjects judged whether the line that was higher in pitch ascended or descended, and from these judgments it was inferred which line was heard as higher and which as lower. It was found that the patterns were perceptually organized so that the simultaneous tones formed proximal relationships. The findings provide evidence that, just as successions of tones tend to be organized perceptually in accordance with pitch proximity, so simultaneous tones tend to be organized in accordance with this principle also.

Research demonstrates that homeless individuals use urban space in adaptive and endemic ways. Investigations at city and neighborhood scales would benefit from attention to homeless use of abandoned housing. We employ the pattern language approach developed by Christopher Alexander for twenty-two abandoned houses in Newark, Ohio. We use statistical and geospatial data analyses to evaluate hypotheses related to prospect and refuge site qualities, accessibility, and attractiveness to homeless persons, and the proximity of sites to resources. Factors related to prospect/refuge, accessibility, and resource proximity were consistent with the hypotheses. Results can be grouped into four distinct patterns: ‘Hiding Places,’ ‘Welcome Mat,’ ‘Shelter (Un)becoming,’ and ‘Proximity to Resources.’ Based on these patterns, we conclude with recommendations for officials and organizations addressing homelessness.

Abstract. Water buffaloes are considered social animals and perform several activities on pasture, such as grazing, moving, standing, ruminating, wallowing, lying, and drinking. However, the way these animals form their social structure in the herd during each one of these activities is still unknown. Literature for water buffaloes has focused mainly on their productive characteristics, impact of grazing on wetlands and behavior during grazing but failed to address the way these animals form their social organization during their activities on pasture. In this study, the tools of social network analysis are used to analyze, detect, and depict the proximity patterns in water buffaloes' activities on pasture and the effect of their age and gender on them. We describe and interpret a series of global and local network indices, and show that the water buffaloes differentiate their social structure in their activities on pasture and that the animals' age and gender affect their interacting patterns, and provide a framework for the application of social network analysis on grazing animals' social behavioral studies. We expect that this framework could be used in future research to provide information regarding the social structure of other kinds of animals that graze in different forage and climatic environments and help animal breeders to improve their management practices.

Due to the widespread application of geographic information systems (GIS) and GPS technology and the increasingly mature infrastructure for data collection, sharing, and integration, more and more research domains have gained access to high-quality geographic data and created new ways to incorporate spatial information and analysis in various studies. There is an urgent need for effective and efficient methods to extract unknown and unexpected information, e.g., co-location patterns, from spatial datasets of high dimensionality and complexity. A co-location pattern is defined as a subset of spatial items whose instances are often located together in spatial proximity. Current co-location mining algorithms are unable to quantify the spatial proximity of a co-location pattern. We propose a co-location pattern miner aiming to discover co-location patterns in a multidimensional spatial data by measuring the cohesion of a pattern. We present a model to measure the cohesion in an attempt to improve the efficiency of existing methods. The usefulness of our method is demonstrated by applying them on the publicly available spatial data of the city of Antwerp in Belgium. The experimental results show that our method is more efficient than existing methods.

Two competing models of the effects of pattern element proximity, masking, and perceptual integration on the discriminability of spatiotemporal vibrotactile patterns are compared. Kirman's ‘integration hypothesis' predicts that pattern perception is facilitated by a process of perceptual integration which requires that pattern elements be presented in close spatial and temporal proximity. Conversely, the ‘isolation hypothesis' predicts that the strong masking effects which occur when pattern elements are presented in close proximity impede the perception of patterns. Traditional masking studies do not provide a fair test of these two hypotheses because they rely on methods that measure the subject's ability to identify the target when the target is presented in conjunction with the mask, rather than the discriminability of the complex percept resulting from the integration of the target and mask. To account for this, a new procedure was devised where the amount of interelement masking and the discriminability of the pattern as a whole were measured independently as the spatial and temporal separation of the pattern elements were varied. As expected under both hypotheses, masking between pattern elements increased as either the spatial or the temporal separation between them was decreased. The pattern discrimination data also support the isolation hypothesis in that the patterns were discriminated less well with increasing temporal element separation with a similar but nonsignificant trend in the case of spatial separation. It is concluded that this new methodology should be applied to a wider range of tactile pattern processing situations in order to assess the generality of the results obtained.

Background: The persistent Covid-19 pandemic tremendously challenged existing work teams as it drove spatial dispersion among colleagues and greater dependence on virtual communication tools. Consequently, teams were required to adapt proven communication practices that mediate the exchange of social information and the perception of proximity to teammates. Aim: We aim to broaden team studies’ theoretical understanding of communication behavior and proximity in the light of contextual changes by developing an empathic understanding of the contemporary phenomena. This entails identifying arisen communication behavior patterns and assessing the impact of behavioral changes on team members’ perception of proximity. Methodology: By conducting a qualitative case study, we investigated three teams of a medium-sized German fashion corporation. The iterative data collection entailed six semi-structured interviews with individuals and focus groups and complementary quantitative surveys. Findings: We posit that sudden spatial dispersion of familiar teams does not inevitable lead to greater perceived distance, but that a team’s ability to appropriate technology, so social needs are met, is decisive. Further, the new communication practices of all teams were found to maintain high levels of synchronicity and social informational value. Yet, communication quality and social exchange was partially hampered by reduced spontaneity, greater passiveness, and a loss of humor. This was found to be strongly influenced by team members’ attitudes towards used technology.

This thesis examines the space use, movement and contact rate patterns of a high- density, group-living, Eurasian badger (Meles meles) population in the UK naturally infected with bovine tuberculosis (bTB). Recently developed proximity logging devices were deployed on a representative sample of 51 badgers from eight different social groups to track their movements using radio-telemetry and to quantify their within- and between-group contact rates. Whilst interactions within social groups accounted for more than 90% of contacts, the entire study population was ultimately connected through interactions among individuals from neighbouring groups. Both within and between-group contacts, and also the use of denning sites, were heavily influenced by seasonal and demographic factors, which appear to be motivated to a large extent by reproductive behaviours. Nevertheless, by using social network analysis I found that badgers that tested positive for bTB were found to interact with fewer of their group members and for a shorter amount of time. Specifically these test-positive individuals were found to associate with test-negative group members significantly less than would be expected by chance. Those animals testing positive for bTB were also found to use outlying setts significantly more frequently than those that tested negative. The within and between-group contact rates of individuals were found to correlate with their sett use patterns. Those animals that spent less time interacting with group members and those that spent more time interacting with members of foreign social groups, were found to spend a greater proportion of their time at outlier setts. The findings in this thesis suggest a link between wider roaming behaviour and the disease status of an individual. This adds support to the argument that the social disruption of badger populations, for example through culling, may promote rather than alleviate the spread of bTB as a result of increased movement and contacts between groups. State-of-the-art technology has enabled me to demonstrate the strong influence that badger social organisation may have on the transmission of an economically significant infectious disease. My findings suggest that disease control measures might be enhanced by taking into account seasonal and individual-level variation in ranging behaviour and use of outlier setts, for example, by identifying and targeting functional groups of individuals, specific areas, or times of the year that contribute disproportionately to disease spread.

Le premier chapitre, coécrit avec Guilaume Daudin, propose une explication du puzzle de la distance. Nous mesurons l'évolution de l'élasticité armingtonienne et établissons qu’elle a augmenté d'au moins 13% entre 1963 et 2009. Or, l’élasticité du commerce à la distance est le produit de cette élasticité et de l’élasticité des coûts de commerce à la distance. Nous en déduisons que la perception de la substituabilité croissante des biens explique l'élasticité non décroissante du commerce à la distance. Le deuxième chapitre établit que les différences de coût des biens intermédiaires contribuent de manière croissante à la détermination de l'avantage comparatif. On montre que l'écart de coût du bien intermédiaire composite pour chaque paire de pays correspond au ratio des indices synthétiques qui mesurent les coûts de commerce payés pour l'accès aux inputs. Comme la part du facteur intermédiaire dans la fonction de production est spécifique au secteur, cet écart devient source d'avantage comparatif. Cet écart explique une part croissante de la variation intersectorielle des exportations: de 3 à 8% entre 1995 et 2009. Nous confirmons l'intuition ricardienne: les différences de savoir-faire technologiques déterminent la spécialisation des pays. Le troisième chapitre exploite la variation dans la structure de l'avantage comparatif des pays émergents et la variation dans leur accès relatif au marché européen en 1996-2007 pour établir que l'élasticité du commerce aux barrières tarifaires en coupe transversale ainsi que la réactivité du commerce à une modification des marges préferentielles sont bien fonction du degré de l'hétérogénéité dans les dotations sectorielles des pays
The first chapter, coauthored with Guillaume Daudin, proposes an explanation of the distance puzzle. We measure the evolution of the Armington elasticity and establish its increase by at least 13% in 1963-2009. As the distance elasticity of trade is the product of this Armington elasticity with the distance elasticity of trade costs, we conclude that the non-decreasing distance elasticity of trade is likely due to an increase in perceived product substitutability. The second chapter establishes that production unbundling has coincided with an inscreasing role of input costs in shaping the pattern of comparative advantage. It is shown that the wedge in the cost of the input bundle across countries is given by a composite index of trade frictions incurred in sourcing inputs. As the cost share of inputs is sector-specific this wedge becomes source of comparative advantage whereby countries characterized by relatively high proximity to input suppliers specialize in sectors which use inputs more intensively. This gap explains an increasing share of the variation in relative sectoral exports: from 3 to 8% in 1995-2009. But consistently with the fundamental intuition of Ricardian models the ranking of relative sectoral technology stocks determines intersectoral specialization. The third chapter exploits variation in the structure of comparative advantage of emerging economies together with variation in their relative access to EU markets in 1996-2007 to establish that trade sensitivity to relative trade costs is decreasing in the degree of endowment dissimilarity. Adverse competition effects are specific to exporter pairs which are sufficiently substitutable in production

In this thesis, we address the issue of fully localizing a known object through computer vision, using a monocular camera, what is a central problem in robotics. A particular attention is here paid on space robotics applications, with the aims of providing a unified visual localization system for autonomous navigation purposes for space rendezvous and proximity operations. Two main challenges of the problem are tackled: initially detecting the targeted object and then tracking it frame-by-frame, providing the complete pose between the camera and the object, knowing the 3D CAD model of the object. For detection, the pose estimation process is based on the segmentation of the moving object and on an efficient probabilistic edge-based matching and alignment procedure of a set of synthetic views of the object with a sequence of initial images. For the tracking phase, pose estimation is handled through a 3D model-based tracking algorithm, for which we propose three different types of visual features, pertinently representing the object with its edges, its silhouette and with a set of interest points. The reliability of the localization process is evaluated by propagating the uncertainty from the errors of the visual features. This uncertainty besides feeds a linear Kalman filter on the camera velocity parameters. Qualitative and quantitative experiments have been performed on various synthetic and real data, with challenging imaging conditions, showing the efficiency and the benefits of the different contributions, and their compliance with space rendezvous applications.

The thesis work intends to provide architecture for mobile local information search service using Wireless LAN and cellular integration. Search technology has been popular and driving business bodies with increasing e-commerce opportunities. The search technology has been recently brought to portable devices such as mobile phones and PDA devices by extending the research scope. Mobile search revenues are expected to surpass Internet search revenues in near future. Mobile local search on the other hand is getting much popular with growing number of mobile subscribers. Mobile phones have been chosen to provide mobile local search services because of its high possessivity and portable nature. In this thesis work, the author would like to propose a generalized architecture for mobile local information search in a new perspective by involving cellular service provider directly with a minimum co-operation from consumers and retailers. When providing mobile local search services, cellular operator has to maintain a replica of databases of all the existing retailers. Updating the replica at cellular operator at regular intervals has been leading to synchronization problems that produce out-dated results to mobile users. The aspects that have driven the author towards proposing the architecture are solving database synchronization problems and thriving for effective search results. The existing architecture of web search, mobile search and mobile local search are analyzed to identify the domain specific challenges and research gaps. Proposed architecture is designed and evaluated by using an approach called Architecture Tradeoff Analysis Method (ATAM). The architecture is evaluated against its quality attributes and the results are presented.

Like melody in general, rock melody is understood to have a hierarchical “grouping structure,” with sub-phrases combining into phrases and then into larger units. A fundamental issue in rock melody is the alignment of melodic groups with meter; while “beginning-accented” groups are the norm, “end-accented” patterns and more irregular patterns also occur. Patterns of repetition—pitch and rhythmic repetition, as well as rhyme—are also important aspects of rock melody. Rock melody sometimes shows independence from the underlying harmony, a phenomenon known as “melodic-harmonic divorce.” Of particular interest is the use of the 3 and flat-3 scale degrees, which are sometimes used in rock melodies in close proximity; related to this is the issue of “blue notes,” notes which fall between the cracks of conventional chromatic-scale categories.

In the past, the tasks of establishing psychological and practical independence were linked in time. Today, these transitions are no longer successively manageable sequences; rather, they are characterized by fluctuations, discontinuities, and reversals. In this review, research findings on factors contributing to the diversity in emerging adults’ leaving home patterns (including early leaving, late leaving, or continued residence in the parents’ home) are summarized. These findings show that although culture, gender, social class, and education shape leaving home patterns, individual factors (e.g., emerging adults’ attachment representations or their progress in the domains of love and work) and parenting strategies that essentially keep the child emotionally and physically in close proximity are also influential. The review reveals that leaving home is an important developmental task for both emerging-adult children and their parents and illustrates how linked their lives are.

This article reviews scholarship on slave culture and the slave experience. Historians of the American South have had an interest in slavery since the early twentieth century but not until fairly recently have they paid sustained attention to the enslaved. Historians have begun to examine slaves, providing a bottom-up analysis of how slavery and slaves shaped their culture, daily lives, and southern white culture generally. This more recent emphasis has been sensitive to the importance of variables: how southern slave culture was shaped by time, place, work patterns, source population (the origins of African-born slaves); whether a region was under English, Dutch, Spanish, Spanish, French, or American jurisdiction; whether slaves lived and worked in societies with slaves or slave societies; whether slaves were skilled, toiled under the task system, or were gang labour; whether they produced tobacco, indigo, rice, sugar, and cotton; their proximity to Native Americans or Spaniards; and whether they lived in times of war or peace.

In a split ergative case pattern, not all subjects that could be marked with ergative case are. A language with a split ergative case pattern is called a split ergative language, but linguists disagree as to what other properties qualify a language as split ergative: an ergative case pattern in combination with a nominative-accusative agreement pattern, or an ergative case and agreement pattern in a language where no syntactic rules make reference to ergative case, or a language with two classes of verbs, only one of which takes an ergative subject. This chapter illustrates the well-known types of ergative splits involving person and aspect, and a range of less well-known types involving stage versus individual level predicates, proximate versus obviate subjects, and different social contexts. Most ergative splits appear to be present in syntax, with the clear exception of person splits which are argued to be purely morphological.

Increasingly, people travel and communicate across borders. Yet, we still know little about the overall structure of this transnational world. Is it really a fully globalized world in which everything is linked, as popular catchphrases like “global village” suggest? Through a sweeping comparative analysis of eight types of mobility and communication among countries worldwide—from migration and tourism to Facebook friendships and phone calls—this book demonstrates that our behavior is actually regionalized, not globalized. The book shows that transnational activity within world regions is not so much the outcome of political, cultural, or economic factors, but is driven primarily by geographic distance. It explains that the spatial structure of transnational human activity follows a simple mathematical function, the power law, a pattern that also fits the movements of many other animal species on the planet. Moreover, this pattern remained extremely stable during the five decades studied—1960 to 2010. Unveiling proximity-induced regionalism as a major feature of planet-scale networks of transnational human activity, the book provides a crucial corrective to several fields of research. Revealing why a truly global society is unlikely to emerge, the book highlights the essential role of interaction beyond borders on a planet that remains spatially fragmented.

AbstractSeamless access to destinations of value such as workplaces, schools, parks or hospitals, influences the quality of life of people all over the world. The first step to planning and improving proximity to services is to estimate the number of trips being made from different parts of a city. A challenge has been representative data available for that purpose. Relying on expensive and infrequently collected travel surveys for modeling trip distributions to facilities has slowed down the decision-making process. The growing abundance of data already collected, if analyzed with the right methods, can help us with planning and understanding cities. In this chapter, we examine human mobility patterns extracted from data passively collected. We present results on the use of points of interest (POIs) registered on Google Places to approximate trip attraction in a city. We compare the result of trip distribution models that utilize only POIs with those utilizing conventional data sets, based on surveys. We show that an extended radiation model provides very good estimates when compared with the official origin–destination matrices from the latest census in Mexico City.

AbstractResidential segregation is known as one of the most prevalent problems of Latin American and Brazilian cities. This chapter looks into the changes in segregation levels in the Metropolitan Region of São Paulo between 2000 and 2010. This period was marked by economic growth and decreasing social inequalities in Brazil with consequent improvement to the quality of life of lower income classes. Despite those improvements, general patterns of urban segregation in Brazilian cities showed remarkable stability, albeit with important changes in the details of segregation patterns. This chapter explores the spatial relationship between socio-occupational groups using global and local segregation indices. The analysis confirmed a highly segregated distribution of social groups in the Metropolitan Region and revealed increased levels of segregation, with global indices figures for 2010 higher than for 2000. Analysis demonstrated that peripheral areas of the Metropolitan Region became more fragmented and heterogeneous in that period, and revealed that their increased heterogeneity is mainly composed of classes with close social proximity, rather than polarised ones. Results showed that while middle classes became more integrated amongst themselves and with lower classes, the separation between lower and upper classes was not only maintained but also increased during the period. All these findings suggest a reconfiguration of the concentric pattern of segregation that maintained a spatial structure of strong social isolation during the period, although with greater complexity.

This paper documents our efforts towards understanding which factors are more relevant in human mobility prediction. Our work is divided into two phases. First, we characterize a dataset consisting of more than 200,000 user check-ins in the Foursquare social network, inferring important patterns in human mobility. Second, we use factorial design to quantify the importance of several types of contextual information in human mobility prediction. Our results show that the proximity of the users possible next check-in to his or her home and work location are the most important factors (among the ones we analyzed) to be used by mobility prediction models.

Proximity printing is one of the lithography processes used in fabricating micro-scale components and systems to transfer mask pattern to the substrate. This paper investigates pattern distortion in the proximity printing process of circular arrays and annulus arrays in micro scale by dimensionless parameters. The effect is analyzed based on the Huygens-Fresnel diffraction theorem. The irradiance distribution exposed on the photoresist at different ξx, the dimensionless parameter representing the ratio of the gap between the mask and the photoresist to the radius of the circular aperture, are investigated. Two dimensional (2D) and 3D irradiance distributions on the projected photoresist for single-aperture, dual-aperture and multi-aperture masks are analyzed and simulated. It showed that diffraction effect, which causes interactions among apertures, increases as ξx decreases. This results in the distortion of the projected pattern in proximity printing. The boundaries between the exposed and shared areas are blurred when ξx increases. The effect of annulus patterns is further investigated by introducing another parameter ξx, the ratio between the radii of the inner and the outer circles. It is found that peaks appear at the center that is supposed no exposure. It also found that the intensity of exposition moves to the outer area when ξx increases. Experiments to verify the simulated distortion is also conducted using a He-Ne laser. The results showed consistency with the simulation and verified that near-field diffraction is the major factor for the pattern distortion as the diffraction becomes stronger when ξx decreases.

The urban population of Africa, the fastest urbanizing continent, has increased from 19% to 39% in the past 50 years, and the number of urban dwellers is projected to reach 770 million by 2030. However, while rapid urbanization has increased mobility and created a subsequent growth in demand for public transport in cities, this has not been met by the provision of adequate and sustainable infrastructure and services. The majority of low-income residents and the urban poor still lack access to adequate transport services and rely on non-motorized and public transport, which is often informal and characterized by poor service delivery. Lack of access to transport services limits access to opportunities that aren’t in the proximity of residential areas, such as education, healthcare, and employment. The urban public transport sector not only faces the challenge of poor service provision, but also of gender inequality. Research shows that, in the existing urban transport systems, there are significant differences in the travel patterns of and modes of transport used by women and men, and that these differences are associated with their roles and responsibilities in society. Moreover, the differences in travel patterns are characterized by unequal access to transport facilities and services. Women are generally underrepresented in the sector, in both its operation and decision-making. Women’s mobility needs and patterns are rarely integrated into transport infrastructure design and services and female users are often victims of harassment and assault. As cities rapidly expand, meeting the transport needs of their growing populations while paying attention to gender-differentiated mobility patterns is a prerequisite to achieving sustainability, livability and inclusivity. Gender mainstreaming in urban public transport is therefore a critical issue, but one which is under-researched in East Africa. This research explores gender issues in public transport in East Africa, focusing in particular on women’s inclusion in both public transport systems and transport policy decision-making processes and using case studies from three cities: Nairobi, Kampala and Dar es Salaam.

Bulk quantitative mineralogy of regolith is a useful indicator of lithological precursor (protolith), degree of weathering, and soil properties affecting various potential landuse decisions. To date, no national-scale maps of regolith mineralogy are available in Australia. Catchment outlet sediments collected over 80% of the continent as part of the National Geochemical Survey of Australia (NGSA) afford a unique opportunity to rapidly and cost-effectively determine regolith mineralogy using the archived sample material. This report releases mineralogical data and metadata obtained as part of a feasibility study in a selected pilot area for such a national regolith mineralogy database and atlas. The area chosen for this study is within the Darling-Curnamona-Delamerian (DCD) region of southeastern Australia. The DCD region was selected as a ‘deep-dive’ data acquisition and analysis by the Exploration for the Future (2020-2024) federal government initiative managed at Geoscience Australia. One hundred NGSA sites from the DCD region were prepared for X-Ray Diffraction (XRD) analysis, which consisted of qualitative mineral identification of the bulk samples (i.e., ‘major’ minerals), qualitative clay mineral identification of the <2 µm grain-size fraction, and quantitative analysis of both ‘major’ and clay minerals of the bulk sample. The identified mineral phases were quartz, plagioclase, K-feldspar, calcite, dolomite, gypsum, halite, hematite, goethite, rutile, zeolite, amphibole, talc, kaolinite, illite (including muscovite and biotite), palygorskite (including interstratified illite-smectite and vermiculite), smectite (including interstratified illite-smectite), vermiculite, and chlorite. Poorly diffracting material (PDM) was also quantified and reported as ‘amorphous’. Mineral identification relied on the EVA® software, whilst quantification was performed using Siroquant®. Resulting mineral abundances are reported with a Chi-squared goodness-of-fit between the actual diffractogram and a modelled diffractogram for each sample, as well as an estimated standard error (esd) measurement of uncertainty for each mineral phase quantified. Sensitivity down to 0.1 wt% (weight percent) was achieved, with any mineral detection below that threshold reported as ‘trace’. Although detailed interpretation of the mineralogical data is outside the remit of the present data release, preliminary observations of mineral abundance patterns suggest a strong link to geology, including proximity to fresh bedrock, weathering during sediment transport, and robust relationships between mineralogy and geochemistry. The mineralogical data generated by this study are presented in Appendix A of this report and are downloadable as a .csv file. Mineral abundance or presence/absence maps are shown in Appendices B and C to document regional mineralogical patterns.

One of the consequences of Russia’s invasion of Ukraine is the imposition of western economic sanctions on the country and further autocratization of its political system. Both factors have resulted in a significant outward migration of Russian citizens, with Central Asia being one of frequent destinations due to the geographic proximity and widespread use of Russian language. At the same time, for many Russians the region remains a terra incognita, perceived primarily through the presence of the Central Asian labour migrants. In this blog piece, ECMI Researcher Aziz Berdiqulov examines this recent phenomenon by discussing specifically the cases of Kazakhstan and Uzbekistan as receiving countries, through the prism of different initiatives addressing the influx, social attitudes concerning the newcomers and reactions of the Russian minorities present there. Furthermore, the author tries to assess whether the new situation has the potential for changing the hitherto pattern of relations between Russians and Central Asians.

The geology of the Montney Formation and the geochemistry of its produced fluids, including nonhydrocarbon gases such as hydrogen sulfide were investigated for both Alberta and BC play areas. Key parameters for understanding a complex petroleum system like the Montney play include changes in thickness, depth of burial, mass balance calculations, timing and magnitudes of paleotemperature exposure, as well as kerogen concentration and types to determine the distribution of hydrocarbon composition, H2S concentrations and CO2 concentrations. Results show that there is first-, second- and third- order variations in the maturation patterns that impact the hydrocarbon composition. Isomer ratio calculations for butane and propane, in combination with excess methane estimation from produced fluids, are powerful tools to highlight effects of migration in the hydrocarbon distribution. The present-day distribution of hydrocarbons is a result of fluid mixing between hydrocarbons generated in-situ with shorter-chained hydrocarbons (i.e., methane) migrated from deeper, more mature areas proximal to the deformation front, along structural elements like the Fort St. John Graben, as well as through areas of lithology with higher permeability. The BC Montney play appears to have hydrocarbon composition that reflects a larger contribution from in-situ generation, while the Montney play in Alberta has a higher proportion of its hydrocarbon volumes from migrated hydrocarbons. Hydrogen sulphide is observed to be laterally discontinuous and found in discrete zones or pockets. The locations of higher concentrations of hydrogen sulphide do not align with the sulphate-rich facies of the Charlie Lake Formation but can be seen to underlie areas of higher sulphate ion concentrations in the formation water. There is some alignment between CO2 and H2S, particularly south of Dawson Creek; however, the cross-plot of CO2 and H2S illustrates some deviation away from any correlation and there must be other processes at play (i.e., decomposition of kerogen or carbonate dissolution). The sources of sulphur in the produced H2S were investigated through isotopic analyses coupled with scanning electron microscopy, energy dispersive spectroscopy, and mineralogy by X-ray diffraction. The Montney Formation in BC can contain small discrete amounts of sulphur in the form of anhydrite as shown by XRD and SEM-EDX results. Sulphur isotopic analyses indicate that the most likely source of sulphur is from Triassic rocks, in particular, the Charlie Lake Formation, due to its close proximity, its high concentration of anhydrite (18-42%), and the evidence that dissolved sulphate ions migrated within the groundwater in fractures and transported anhydrite into the Halfway Formation and into the Montney Formation. The isotopic signature shows the sulphur isotopic ratio of the anhydrite in the Montney Formation is in the same range as the sulphur within the H2S gas and is a lighter ratio than what is found in Devonian anhydrite and H2S gas. This integrated study contributes to a better understanding of the hydrocarbon system for enhancing the efficiency of and optimizing the planning of drilling and production operations. Operators in BC should include mapping of the Charlie Lake evaporites and structural elements, three-dimensional seismic and sulphate ion concentrations in the connate water, when planning wells, in order to reduce the risk of encountering unexpected souring.

In this study we investigated coda-wave attenuation (QC) from the eastern Canadian Arctic in Nunavut and the Hudson Bay complex including portions of northern Manitoba, Ontario, Quebec and Labrador. We used earthquake recordings from 15 broadband and 3 short period seismograph stations of the Canadian National Seismic Network (CNSN) and 29 broadband stations of the POLARIS network across the region. Our dataset is comprised of 637 earthquakes recorded between 1985 and 2021 with magnitudes ranging from 1.3 to 6.1, depths from 0 to 20 km and epicentral distances of 5 to 100 km. This gives a total of 246 high signal-to-noise (S/N) traces (S/N[lesser/equal]5.0) useful for QC calculation (with a maximum ellipse parameter, a2, of 100) across the region. Coda windows were selected to start at tc = 2tS (two times the travel time of the direct S wave), and were filtered at center frequencies of 2, 4, 8, 12 and 16 Hz. Our study reveals a consistent pattern. We find that in the northern section of the study area, the highest Q0 values (e.g., Q0 of 110 and 112) are at station POIN and station RES, respectively, which are located in the older Archean province. The lowest Q0 values that we find (e.g., Q0 of 55 and 61) are at station AKVQ and IVKQ respectively, located in northern Quebec. Smaller Q0 values for stations in the south are explained by the younger age of the rocks and proximity to the main fault systems. An average for all the data results in a Q relationship of QC = 82f1.08 for the frequency band of 2 to 16 Hz for the entire region.
