Pełny tekst źródłaNo cenário atual das telecomunicações móveis, os arranjos de antenas voltaram a receber grande atenção dos pesquisadores, especialmente quando esquemas adaptativos de modificação de seus diagramas de radiação são utilizados. Uma das aplicações que exploram o potencial dos arranjos de antenas é o seu uso como forma de aumentar consideravelmente a eficiência espectral dos sistemas móveis atuais e da próxima geração. A outra aplicação em evidência está voltada para sistemas de localização de posição, pois algumas das técnicas conhecidas envolvem a estimação de ângulos-de-chegada usando arranjos de antenas. Diante destas possibilidades, cresce em importância o estudo das variações do canal de propagação rádio móvel no domínio em que o uso dos arranjos de antenas atua: o espacial. O presente trabalho procura contribuir para o contexto em questão, com uma investigação experimental do canal real rádio-móvel nos domínios temporal (retardos) e espacial (ângulos-de-chegada). No que se refere ao contexto nacional, contribuições similares baseadas em simulações já são encontradas; baseadas em medidas não. Em particular, sondagens na faixa de 1,8 GHz em ambientes internos típicos foram realizadas. Duas técnicas distintas de sondagem temporalespacial foram implementadas, tomando por base uma sonda de canal faixa-larga montada e testada com sucesso, como contribuição principal de uma dissertação de mestrado recentemente apresentada por um integrante do mesmo grupo de pesquisa ao qual esta tese está vinculada. Uma das técnicas sintetiza o arranjo realizando as sondagens com uma única antena que é sucessivamente deslocada para ocupar as posições correspondentes às dos elementos do arranjo. A outra técnica emprega um arranjo real. Em ambas, a configuração mais simples para um arranjo foi utilizada: a linear uniforme. As sondagens não forneciam diretamente os espectros espaciais-temporais. As estimativas dos espectros foram processadas posteriormente, aplicando técnicas como o correlograma para o domínio do retardo, e quatro técnicas distintas para o domínio espacial, que foi o foco principal deste trabalho: duas convencionais; e duas paramétricas, com potencial de aumentar a resolução das estimativas, assumindo hipóteses razoáveis sobre as respostas esperadas. De posse das respostas espectrais estimadas, comparações com estimativas teóricas permitiram uma análise de desempenho das técnicas utilizadas. Adicionalmente à investigação experimental do canal espacial, procurou-se verificar o potencial da aplicação da teoria de wavelets ao estudo do canal rádiomóvel. Em especial, uma das principais aplicações daquela teoria foi testada como técnica de pós-processamento das respostas espectrais no domínio do retardo. A supressão de ruído por decomposição wavelet foi aplicada a um vasto conjunto de medidas de canal disponíveis, fruto de trabalhos anteriores do grupo de pesquisa ao qual esta tese está vinculada, com resultados expressivos.
In the present mobile communications scenario, researchers have turned once again special attention to antennae arrays, particularly when adaptive schemes are employed to modify its radiation patterns. One of its main applications results in considerable increases to the spectral efficiency of present and next generation mobile systems. The other major application is headed towards position location systems, since some of the known techniques comprise angle-of-arrival estimation using antennae arrays. Under such possibilities, mobile radio propagation channel variations studies grow in relevance, specially regarding the antennae arrays main domain of action: the spatial domain. The present work tries to contribute to the overstated context, experimentally investigating the actual mobile radio channel over the temporal (delays) and spatial (angles of arrival) domains. Regionally speaking, similar contributions based on simulations are already found, but none based on measurements. In special, 1.8 GHz indoor soundings have been carried out. Two different temporal spatial sounding techniques have been deployed, based on na available wideband channel sounder successfully assembled and tested as the major contribution of a MSc. dissertation recently presented by a member of the same research team to which this thesis belongs. One of such techniques sinthesyzes the array carrying the sounding out with a single antenna, which is successively moved to occupy the spots corresponding to the array elements. The other method employs an actual array. For both cases, the simplest array configuration has been used: the uniform linear one. Space-time spectra were not directly available in real time during the soundings. Its estimates have been processed later, applying techniques such as the correlogram over the delay domain, and four distinct methods over the spatial domain, the main focus of the present work. Two conventional methods have been used, as well as two parametric ones, potentially capable to increase the estimates resolution, assuming reasonable hypotheses regarding the expected responses. With the estimated spectral responses in hands, comparisons with theoretical estimates allowed a performance assessment of the employed methods. In addition to the spatial channel experimental investigation, the wavelets theory potential of application to the mobile-radio channel study has been checked out. Notably, one of the wavelets theory major applications has been tested as a post-processing technique to improve delay-domain spectral responses. Wavelet decomposition based de-noising has been applied to a huge measurements ensemble, available as the product of previous works of the research group to which this thesis is attached, leading to remarkable results.
Cocco, Helen. "Seamless shopping in omnichannel retailing : the effect of channel integration on consumers’ responses". Thesis, Lille 1, 2020. http://www.theses.fr/2020LIL1A010.
Pełny tekst źródłaChanging consumer shopping behaviours are challenging retailers to deliver seamless experiences. Consumers now have a plethora of available shopping channels that they use, often simultaneously throughout the search, purchase and post-purchase phases of the shopping experience. With the evolution of mobile technology advancing multiple channel shopping, consumers now expect seamless shopping. For retailers, these expectations often represent technological and operational challenges, where several complications can exist in linking channels, devices and touchpoints. A lack of channel integration can cause disruption and inconvenience, whereas well integrated channels lead to consistent, continuous and uninterrupted shopping journeys that promote desirable consumer behavioural outcomes. These challenges have led many retailers to develop omnichannel strategies, which focus on creating seamless customer experiences. Companies now compete on customer experience and therefore, offering seamless shopping has never been so pertinent. This dissertation contributes to the emerging field of customer experience research by providing insightful understanding into what, how and under what conditions, consumers experience seamless shopping. Firstly, a conceptualization of seamless shopping provides much needed clarity for research and practice, ensures more accurate usage and supports further theoretical development. Although existing research indicates the importance of seamless shopping in marketing, there is little knowledge about what the term is comprised of, and its constituent parts. Secondly, based on this conceptualization, a 7-item measurement scale is established to aid its implementation both in literature and in practice. The partnering of conceptualization and scale development broadens the concept’s scope and adoption in practice. Thirdly, on a theoretical level, we develop a framework that links seamless shopping with established marketing constructs. This answers calls for more research on drivers of consumers’ seamless purchases by establishing channel integration as a means to creating seamless shopping. The framework also extends the research by predicting several beneficial consequences of seamless shopping. This conceptual framework is empirically examined or a second country retail environment, which strengthens the impact of this research in an international context. Finally, this study builds on previous research by examining customer psychographic characteristics that impact the channel integration-seamless shopping relationship. Results identify where retailers should allocate more time and effort into channel integration initiatives to achieve seamless shopping, and the corresponding desirable outcomes. This dissertation places a valuable lens on seamless shopping in omnichannel retailing and the findings provide valuable academic and practical insights in the customer experience field

Pełny tekst źródłaMclean, Matthew. "Functional responses of fish communities to environmental gradients in the North Sea, Eastern English Channel, and Bay of Somme". Thesis, Littoral, 2019. http://www.theses.fr/2019DUNK0532/document.
Pełny tekst źródłaThe ensemble of biological, geochemical, and physical processes that occur within ecosystems is driven by the interplay between biological communities and the abiotic environment. Explaining the spatial and temporal dynamics of biological communities in relation to environmental conditions is therefore essential for understanding ecosystem functioning, and ultimately for achieving sustainable development. In marine ecosystems, fish communities are key to ecosystem functioning, and fisheries provide livelihoods for over 10% of the world’s population. However, understanding the processes structuring fish communities remains difficult because community structure varies with both natural environmental fluctuations and, increasingly, human pressures. Effectively managing fisheries and marine ecosystems under global change therefore requires better characterizing fish community dynamics over time and space and disentangling the underlying drivers and mechanisms. While fish ecologists have traditionally relied on species-based approaches (i.e., taxonomic approaches) to study community structure, trait-based approaches (i.e., functional approaches) are increasingly used because they can provide better insight into community assembly and the mechanisms driving community responses. To meet this need for a better understanding of biodiversity dynamics, the present thesis took advantage of long-term scientific monitoring data to characterize the functional responses of fish communities to environmental gradients in the North Sea, Eastern English Channel, and Bay of Somme. All three ecosystems experienced temperature rises and oceanographic changes associated with a warming phase of the Atlantic Multidecadal Oscillation (AMO), which rapidly impacted fish community structure. Consistent biological responses were observed across the three ecosystems despite their different spatial scales, demonstrating that fish communities were affected by environmental change through bio-ecological traits associated with habitat preference and life history. In the North Sea and Eastern Channel, pelagic species were the most responsive and contributed largely to community dynamics, which is likely explained by their greater mobility, higher dispersal rates, and fewer habitat requirements. However, beyond habitat preference, species with r-selected life histories (e.g., low size and age at maturity, low parental investment, small offspring) had the fastest environmental responses whether or not they were pelagic, likely due to their rapid population turnover and generation time. Importantly, the way these species’ responses shaped community structure depended on environmental context. R-selected, pelagic species rapidly declined in the Bay of Somme and Eastern Channel, but rapidly increased in the North Sea. This likely reflects environmental suitability, indicating that after the phase change of the AMO, the Eastern Channel became a less favorable environment for these species, while the North Sea became more favorable. Thus, species with high mobility and fast life history cycles appear capable of rapidly tracking environmental conditions, shifting in abundance in response to environmental suitability. Additionally, as these ecosystems have warmed over the last 30 years, community responses were characterized by increases in mean thermal preference. Importantly, the amplitude of community changes was partially determined by communities’ initial structure and redundancy of bio-ecological traits, showing that community responses depended not only on environmental changes but also on biodiversity itself. Lastly, while fish community responses were consistently associated with climatic changes, historical fishing pressure on large-bodied, demersal species appeared to render fish communities more sensitive to environmental changes by increasing the relative of abundance of pelagic and r-selected species

Ellis, Lee David. "Potassium channel control of neuronal frequency response". Thesis, McGill University, 2007. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=103381.
Pełny tekst źródłaI have cloned 3 small conductance (SK) calcium activated potassium channels from cDNA libraries created from the brain of Apteronotus. I have subsequently localized the AptSK channels throughout the brain using both in situ hybridization (AptSK1, 2 & 3) and immunohistochemical (AptSK1 & 2) techniques. The 3 channels showed distinct expression patterns, with the AptSK1 & 2 channels showing a partially overlapping expression pattern, while AptSK3 appears to be expressed in unique areas of the brain. In the ELL AptSK1 & 2 show a partially overlapping expression pattern, appearing in similar pyramidal neurons. However, their distribution within individual cell is unique, with AptSK1 showing a dendritic localization, while AptSK2 is primarily somatic. We have demonstrated that the unique expression pattern of the somatic AptSK2 channel in the ELL coincides with the functional SK currents evaluated through in vitro electrophysiology. Further we have shown that neurons that encode low frequencies do not possess functional SK channels. It thus appears that the presence of the AptSK2 channel subtype can predispose a neuron to respond to specific types of sensory signals.
In an attempt to evaluate if second messengers could modify the AptSK control of frequency tuning I investigated the consequences of muscarinic acetylcholine receptor (mAChR) activation on a pyramidal neurons response patterns. While it had been shown in vivo that mAChR activation increased a pyramidal neuron's response to low frequencies, I have found that this was not due to a decrease in AptSK current, but rather appears to be the result of a down-regulation of an A-type potassium channel.
Taken together the studies that comprise this thesis show how the selective expression of a single potassium channel subtype can control a sensory neurons response to specific environmental cues. The secondary modulation of the A-type current highlights the potential for a second messenger to control a neuron's sensory response through the down-regulation of constitutively expressed potassium current.

The response of bedrock channels to external forcings is investigated in this thesis. The approach is to test and constrain a theoretical model for bedrock-channel incision based on shear stress using field data. The primary study area is a series of 21 small, coastal drainage basins in northern California, USA with known, varying rates and history of rock uplift. The initial application of a simple form of the model to the stream profiles suggests that (1) the channels are eroding at rates approximately equal to uplift rates (i.e. steady-state fluvial incision), and (2) erosion processes are proportionally more effective in the high-uplift-rate zone, with factors in addition to channel gradient responding to tectonic forcing. These results lead to the rest of the study, in which some of the assumptions of the simple model are rejected in order to explain the second observation. A more sophisticated model that includes both a stochastic distribution of floods and a threshold shear stress to initiate bedrock erosion predicts that a greater part of the distribution of flood events will exceed the threshold in steeper channels. Therefore, higher-gradient channels have proportionally higher erosion rates, as is observed in the high-uplift-rate streams of the California field site. The shear-stress model is tested and constrained through a detailed, field-based analysis of topography, lithology, stream morphology and regional hydrology to isolate those factors that respond to tectonics. The stochastic model is able to incorporate the observed variation in stream discharge due to orographic enhancement of precipitation by high topography associated with high uplift rates.
(cont.) This increase in discharge appears to play a second-order role in setting the erosional effectiveness of the high-uplift zone. Other factors, including channel width, lithologic resistance and sediment flux, do not appear to vary in an important way with uplift rate, although this conclusion is based on analyses that have some limitations. The importance of thresholds is underscored by a direct calculation of critical shear stress during a rare bedrock-incision event in a low-erosion-rate creek in New York state (= 100-200 Pa). This event, the only one that caused significant bedrock plucking at the site in an -40-year period, is consistent with a low erosion rate, with few events that exceed the threshold. In contrast, similar 'z values are exceeded during high-frequency flood events in the steep, rapidly eroding California streams. Inclusion of an erosion threshold accounts for the observed relationship between channel gradient and rock-uplift rate in the California site. In summary, by using field examples, the shear-stress bedrock-incision model with a stochastic distribution of flood events and an erosion threshold is demonstrated to be an effective and powerful tool for exploring relationships amongst climatic, tectonic and surficial processes. In the final section of this thesis, a numerical modeling study couples the shear-stress model for onshore fluvial incision with a simple rule for offshore wave-based erosion of bedrock to explore the response of uplifting streams to eustatic fluctuations ...

Pełny tekst źródłaIl est admit que le courant potassique sortant Ito est diminué de façon importante dans l'insuffisance cardiaque induite par un contexte d'hypertrophie ventriculaire et de tachystimulation. Plus précisément, des travaux précédents de notre laboratoire montrent que l'insuffisance cardiaque induite par tachystimulation ventriculaire chez le chien favorise les arythmies ventriculaires létales et la mort subite. Une réduction du courant Ito dans les ventricules a été démontrée dans ce modèle. Afin de mieux comprendre comment la tachystimulation (tachycardie ventricu-laire soutenue) affecte les propriétés électriques des cardiomyocytes ventriculaires, nous avons comparé l'effet de la tachystimulation in vitro sur le courant potassique Ito de cardiomyocytes de l'épicarde et de l'endocarde ventriculaire de chien. Le courant Ito de cardiomyocytes de l'epicarde et de l'endocarde à été enregistré à l'aide de la technique de patch-clamp en configuration cellule entière après 24h de culture sous tachystimulation continue a 1-Hz (rythme normal) ou 3-Hz (tachycardie). Les transi-toires calciques ont été étudiés (Indo1-AM) après 0, 2, 4, 8 et 24hr de stimulation a 1-Hz ou 3-Hz. L'analyse de la dépendance au voltage des processus d'inactivation et de réactivation du courant Ito n'a démontré aucune différence entre les cellules de l'épicarde et de l'endocarde, ni même entre 1-Hz et 3-Hz. De façon intéressante, la tachystimulation (3-Hz) réduisait la densité du courant Ito et l'expression des ARNms codant pour le canal Kv4.3 dans les cellules de l'épicarde mais pas dans l'endocarde. La chélation du calcium intracellulaire à l'aide du BAPTA-AM, prévenait cette diminution de Ito dans les cellules de l'épicarde entrainant une augmentation de ~47% du courant. Dans les cellules de l'endocarde, le BAPTA-AM provoquait une augmentation de ~200%. De façon cohérente avec une sensibilité des cellules de l'endocarde plus importante à la chélation de calcium, l'amplitude des transitoires calciques était plus importante dans les cellules de l'endocarde (85±4 nM) que dans les cellules de l'épicarde (46±2 nM). Alors que l'amplitude des transitoires calciques n'était pas modifiée par la tachystimulation dans les cellules de l'endocarde, une augmentation précoce était me-surée dans les cellules de l'épicarde (i.e. 64.2±4.2 vs 40.7±3.5 nM). L'inhibition de la voie de signalisation NFAT/calcineurine prévenait la diminution d' Ito dans les cellules de l'épicarde soumises à la tachystimulation et restait sans effet sur le courant Ito des cellules de l'endocarde.Nos résultats montrent que les cellules adultes de l'épicarde et de l'endocarde répondent de façon différente suite à une tachystimulation. Ce processus est possiblement lié à un contrôle différentiel de la signalisation induite par le calcium.
