description: Diese Arbeit zeigt eine Übersicht des derzeit am Institut für Flugsysteme verfolgten Ansatzes zur Lösung der Beanspruchungsproblematik in bemannt-unbemannten Multi-UAV Hubschraubermissionen. Mit Hilfe kognitiver Software-Agenten wird die Hubschrauberbesatzung auf zweierlei Weisen unterstützt. Zum einen wird die Arbeit der Piloten durch die auftragsbasierte Führung der unbemannten Luftfahrzeuge mit automatisiertem Sensoreinsatz in einem delegierenden Verhältnis erleichtert, zum anderen wird der Besatzung ein kognitives Assistenzsystem in einem kooperierenden Verhältnis zur Seite gestellt. Die Unterstützung findet dabei sowohl bei der Missionsplanung, als auch bei der Missionsdurchführung statt. Um Mensch-Maschine Probleme zu vermeiden, ist die verwendete Automation nicht starr, sondern bietet dem Operateur je nach Situation variable Eingriffsmöglichkeiten. Das für das Assistenzsystem notwendige a-priori Wissen, um die Beanspruchung maschinell und kontextreich abschätzen und auf dessen Basis adaptiv intervenieren zu können, wird durch ein Pilotenaufgabenmodell zur Verfügung gestellt. Der Ansatz ist in Form von echtzeitfähigen Softwaremodulen in einem Hubschrauber-Missionssimulator implementiert.

description: This study investigated effects of physical activity on children with Specific Learning Disorder (SLD)’s self-concept. Eighteen children with SLD participated in the SPARK for Learning program which involved 20 minutes of physical activity each school day. These children were matched one-to-one by age and gender to children with SLD who did not participate in the program. Ratings of children’s self-concept were garnered at two different time points. Findings indicated that SPARK for Learning participation did not impact children with SLD’s overall self-concept. However, children with SLD who participated in the program viewed themselves as happier and more satisfied with life at the end of the school year compared to those children who did not participate. This study has important implications for children with SLD as high intensity physical activity may lead to happier children in the school environment despite having a disorder that impacts them socially, emotionally, behaviorally and academically.

description: No ensaio intitulado ‘O Legado Teórico dos Estudos Culturais’, Stuart Hall procura traçar a genealogia desta disciplina, focando as relações de poder e de conhecimento visíveis nos três principais momentos de viragem dessa formação discursiva, nomeadamente o declínio do marxismo ortodoxo, o surgimento do feminismo e a emergência da questão racial. Insurgindo-se contra uma narrativa historicista dos estudos culturais, segundo a qual estes teriam um único ponto de origem, Hall distancia-se de uma visão teleológica e evolutiva: patente no seu artigo está a ideia de que os estudos culturais são uma disciplina sem fronteiras rigidamente demarcadas, redefinindo-se consoante as especificidades sociais, políticas e económicas que assinalam uma determinada conjuntura. Esta característica não constitui, obviamente, monopólio dos estudos culturais, estendendo-se a qualquer outra disciplina; no entanto, por se distinguirem pela abertura à alteridade, seja esta considerada em termos de classe, género ou raça, pressupõe-se uma maior autorreflexividade nos estudos culturais do que noutras disciplinas. Subjacente à genealogia de Hall está uma desconfiança relativamente à superficialidade dessa abertura: nos referidos momentos de viragem constatam-se tentativas de defender o território disciplinar de ingerências conjunturais externas.

description: A simple one-dimensional model is proposed, in which N spinless repulsively interacting fermions occupy M>N degenerate states. It is argued that the energy spectrum and the wavefunctions of this system strongly resemble the spectrum and wavefunctions of 2D electrons in the lowest Landau level (the problem of the Fractional Quantum Hall Effect). In particular, Laughlin-type wavefunctions describe ground states at filling factors v = N/M = 1(2m+1). Within this model the complimentary wavefunction for v = 1-1/(2m + 1) is found explicitly and extremely simple ground state wavefunctions for arbitrary odd-denominator filling factors are proposed.

description: Molecular transport across the cell membrane is an important and highly regulated process. Secondary transporters are a large family of integral membrane proteins responsible for mediating molecular exchange. Pre-existing ion gradients are utilized to drive secondary transport. Our focus was on the solute carrier (SLC) family of secondary transporters, specifically those that utilize Na+ to drive transport. The SLC family can be further classified as a sodium substrate symporter (SSS). Specifically, we focused on the human serotonin and dopamine transporters (SLC6) and iodide symporters (SLC5). The sodium electrochemical potential is coupled to the energetically unfavourable transport of the substrate. This yields a net favourable translocation of the substrate and co-transported ions. Little structural information is available on the SSS family transporters and even less when only the human variants are considered. This prompted an attempt to predict human protein structures using the available data from bacterial homologues to fill the knowledge gap. The methodology was based on the X-ray structures of the leucine transporter (LeuT) and sodium galactose transporter (vSGLT). Through our structural alignments we were able to identify the ion binding sites. With the help of Glide docking software, we successfully identified substrate and inhibitors binding sites. Molecular dynamics were used to simulate biologically relevant systems and find the forces driving substrate and ion binding. Our computational biochemistry approach has proven to be a reliable method to study the transport and substrate interactions. In addition, our collaborative efforts successfully merged theoretical and experimental science.

Irrelevant Digital Objects

description: We present the design basics of the cognitive companion Dare2Del which supports humans to temporarily ignore or permanently forget digital objects. The system infers the irrelevancy of digital objects based on a symbolic knowledge representation and white box machine learning. The logic-like knowledge base of the system is split in facts that apply to individual digital objects (data) and general rules which hold for all objects in the domain (domain theory). The irrelevancy of digital objects is inferred using explicit rules, which are learned by an inductive logic programming approach. In this paper, we focus on the knowledge base and the inference for the permanent deletion of files. First, we present relations available for data and domain theory. Then, we evaluate whether the chosen relations are suitable for inferring the irrelevancy of files. We evaluate a handcrafted irrelevancy rule on an artificial file system with 500 files. For that, we developed a generator for knowledge bases of artificial file systems. We were able to classify 97.2% of the files correctly as irrelevant or relevant.

description: Transition periods in medical education are associated with increased risk for learners and patients. In pediatric surgery, the transition to specialty is especially difficult as learners adjust to new patient populations. In this study we performed a targeted needs assessment to determine the ideal content and format of a pediatric surgery boot camp to aid in the transition to residency. The survey was distributed to pediatric surgery residents and staff across North America. No significant differences were identified between staff and residents in survey responses. The top 5 topics identified for inclusion in a boot camp were: 1) Fluid and electrolyte management, 2) Appendicitis, 3) Pediatric Hernias, 4) Nutrition and 5) Pain Management. The preferred duration for a boot camp was 3-4 days using a variety of educational methods including e-learning, simulation and small group teaching. Based on results of the needs assessment survey, a novel pediatric surgery boot camp curriculum can be developed.

We obtain the maximum channeling efficiency to be 22.0 (\pm4.8)% at fiber diameter of 350 nm for the emission wavelength of 780 nm. The results may open new possibilities in quantum information technologies for generating single photons into single-mode optical-fibers.

description: Tal como as outras dimensões identitárias são negociadas face à diferença (Hall, 1991), também a etnicidade é um processo dinâmico e relacional, só sendo o conceito útil às ciências sociais se contrariar a ideia de que os grupos étnicos existem devido a diferenças essenciais. Porém, a carga ideológica do conceito leva o senso comum a usá-lo como forma polida de designar outras ‘raças’. É assim que os média europeus falam em etnia para populações de origem africana ou asiática, mas raramente o fazem para migrantes da Europa. Na perspectiva que adopto, a etnicidade não tem simplesmente a ver com diferença, de cultura ou de fenótipo, mas sim com a sua significação como elemento que interfere nas relações sociais. Quando determinada identidade influi no acesso ao mercado de trabalho ou na escolha de parceiros conjugais, está-se perante situações de etnicidade. A etnicidade é, pois, a diferença tornada socialmente significativa, a partir da ideia de origem (Eriksen, 2001). Abordo aqui a participação dos média na construção ou desconstrução desses significados.

description: Characteristics of Cloud to Ground (CG) lightning over Alberta, Canada were investigated by using 2010-2016 lightning data with data mining methods. The hotspot analysis was implemented to find the regions with high frequency CG lightning strikes clustered together. Generally, hotspot regions are located in central, central east and south central regions of the study regions. About 94% of annual lightning occurred in warm months (June to August) and the daily lightning frequency was influenced by diurnal heating cycle. The CG lightning frequency associated with land properties was investigated by measuring preference index (PI). The association rule mining technique was used to investigate frequent CG lightning patterns, which were verified by similarity measurement to check the patterns’ consistency. The verification of CG lightning hazard map generated with 2010-2014 data was carried out by comparing it to unprocessed raw CG lightning data from 2015-2016. The similarity coefficient values indicated that there were high correlations throughout the entire study period. The actual CG lightning generally occurred more frequently in higher risky regions in the lightning hazard map. Most wild fire (around 93%) in Alberta occurred in forests, wetland forests and wetland shrub areas. It was also found that lightning and wild fire occur in two distinct areas: frequent wild fire region with a high frequency of lightning, and frequent wild fire region with a low frequency of lightning. Further, preference index (PI) revealed locations where the wild fires occurred more frequently than in other class regions. As one of the potential applications of this research, the wild fire hazard area was estimated with the CG lightning hazard map and specific land use types.

description: We report on a systematic implementation of su(2) invariance for matrix product states (MPS) with concrete computations cast in a diagrammatic language. As an application we present a variational MPS study of $su(2)$ invariant quantum spin systems. For efficient computations we make systematic use of the su(2) symmetry at all steps of the calculations: (i) the matrix space is set up as a direct sum of irreducible representations, (ii) the local matrices with state-valued entries are set up as superposition of su(2) singlet operators, (iii) products of operators are evaluated algebraically by making use of identities for $3j$ and $6j$ symbols. The remaining numerical computations like the diagonalization of the associated transfer matrix and the minimization of the energy expectation value are done in spaces free of symmetry degeneracies. The energy expectation value is a strict upper bound of the true ground-state energy and yields definite conclusions about the accuracy of DMRG results reported in the literature. Furthermore, we present explicit results with accuracy better than $10^{-4}$ for nearest- and next-nearest neighbour spin correlators and for general dimer-dimer correlators in the thermodynamical limit of the spin-1/2 Heisenberg chain with frustration.

Tomando a telenovela brasileira O Clone, transmitida em Portugal entre Dezembro de 2001 e Setembro de 2002, como um exemplo da indústria cultural televisiva, difusora de imagens da Identidade e da Diferença, do Eu e do Outro, pretendemos compreender, junto de uma amostra da Comunidade Islâmica de Lisboa, até que ponto a recepção deste produto de ficção desencadeou a proliferação e a redefinição de identidades e estilos de vida, resultando em fenómenos de hibridação cultural. Para tal, numa primeira fase, recolhemos e analisámos alguns materiais audiovisuais referentes à telenovela. Numa segunda fase, constituímos uma amostra de muçulmanos sunitas de origem indo-moçambicana, junto de quem desenvolvemos uma pesquisa de terreno e a análise de recepção. No que se refere a resultados obtidos, observámos que se verifica, ao nível da recepção, uma estreita relação entre os géneros ficcionais e os tópicos de agenda mediática (géneros informativos). Por sua vez, constatámos a relevância da mediação de outros produtos mediáticos e indústrias culturais globais na definição das identidades, não sendo possível verificar de forma categórica que os processos de hibridação cultural ocorrem na sequência da recepção de um só produto da indústria cultural televisiva.

description: Beliefs seem to be more significantly constrained by some norms than others e.g. one should only believe what they have sufficient evidence for, a belief that p is correct iff p is true etc. I call these norms, doxastic norms. Constitutivism is the view that doxastic norms are a constitutive feature of belief. I argue that this view is mistaken. In making this case, I come to defend views about the semantics of doxastic norms, the nature of belief, and the value of truth. Doxastic norms are naturally stated in deontic terms. In the first chapter, I consider how we should best understand these statements, given that we likely don't control our beliefs in the same way that we do our actions. In the second chapter, I consider whether the account of religious belief given by either Ludwig Wittgenstein or Søren Kierkegaard provide a counterexample to constitutivism. In the third chapter, I argue that constitutivism can't account for certain intuitions about our reasons for belief. In the fourth chapter, I defend a descriptive account of belief in terms of the appearance of truth. In the fifth chapter, I show how my view can better account for the data which is thought by some to support constitutivism. In the final chapter, I describe how our reasons for belief might arise from our goals.

description: Objective of the study was to analyze the current physical education service situation in the context of the modern educational paradigm with the higher education system reforms and new higher education system standards. Methods and structure of the study. During the study, we applied a battery of theoretical methods including analysis, synthesis, comparison, and generalization of paradigmatic approaches in higher education, as well as traditional and alternative educational concepts of physical education. Results and conclusions. We identified the orientation of the scientific paradigms in education; made a theoretical generalization of the accumulated knowledge and experience in the field of physical education from the perspective of the paradigmatic approach; showed the role and place of physical education in the structure of the state higher education standards; disclosed the structural and content base of the thematic sections of the sample physical education program. Based on the results of the theoretical analysis, the authors conclude that the current reality of higher education implies the implementation of alternative concepts of educational activity into the long-standing traditional teaching practice. The contradiction between the objective requirements of the society for the level of development of physical education competences and the prevalence of a practical-oriented approach to the formation of educational functions necessitates the development of a theoretical-methodological grounds for educational technologies from a paradigmatic perspective. In terms of actualization of the Federal State Education Standard, the higher education standard ensures that mandatory requirements are met when future specialists develop competences to support an adequate physical fitness level to provide for full-fledged social and professional activities.

description: Radiation therapy breast treatment plans are developed using a static computed tomography image that does not account for intrafraction motion during treatment. Motion during breast radiotherapy can result in suboptimal plan quality, decreased target coverage, and increased dose to organs at risk. This thesis examines two sources of respiratory motion during breast radiotherapy: (1) free-breathing motion, and (2) residual motion during deep inspiration breath hold. The effect of free-breathing motion was examined for external beam accelerated partial breast irradiation (APBI). Using existing volunteer respiratory motion data and patient APBI treatment plans, a population-based margin formula based on respiratory motion amplitude was derived. Deep inspiration breath hold (DIBH) is used in breast radiotherapy to alter patient anatomy during treatment and subsequently reduce heart dose. We conducted a planning study demonstrating that DIBH provides the most cardiac dose sparing benefit for patients receiving locoregional irradiation including the internal mammary chain (IMC) nodes. DIBH is a difficult manoeuvre to achieve and maintain, and the associated uncertainties may be larger than conventional free-breathing treatments. The positional uncertainties of the breast and heart were characterized for a low-resource, manually-gated DIBH technique. We found that the manual technique had larger positional uncertainties than more resource-intensive gating methods; however, the dosimetric impact of these larger uncertainties was unknown. To determine the dosimetric impact of breath hold level variance on locoregional DIBH treatments, we conducted a study to collect patient residual DIBH motion data over a treatment course. These data were used in a motion escalation modelling study with the aim of determining the impact of increasing residual DIBH motion on target coverage, cardiac dose, and plan quality. We found that intrafractional residual breath hold motion has minimal effect on heart dose and target coverage for most patients; however, coverage can be degraded for even small DIBH uncertainties in the posterior direction. This can be mitigated by adapting processes to reduce shallow breath hold errors and/or accounting for known errors in planning. The results from the investigations presented in this thesis have led to change in clinical practice at our centre.

description: Theoretical studies of synchronization are usually based on models of coupled phase oscillators which, when isolated, have constant angular frequency. Stochastic discrete versions of these uniform oscillators have also appeared in the literature, with equal transition rates among the states. Here we start from the model recently introduced by Wood et al. [Phys. Rev. Lett. 96}, 145701 (2006)], which has a collectively synchronized phase, and parametrically modify the phase-coupled oscillators to render them (stochastically) nonuniform. We show that, depending on the nonuniformity parameter $0\leq α\leq 1$, a mean field analysis predicts the occurrence of several phase transitions. In particular, the phase with collective oscillations is stable for the complete graph only for $α\leq α^\prime < 1$. At $α=1$ the oscillators become excitable elements and the system has an absorbing state. In the excitable regime, no collective oscillations were found in the model.

description: The tailoring of various garnet-type ceramic electrolytes for applications in energy conversion and storage was achieved in this thesis. For proton exchange membrane fuel cells, the garnet-type Li5+xBaxLa3-xNb2O12 (x = 0, 0.5, 1) was modified through a H+/Li+ ion-exchange reaction using water. The use of other exchange media including acetic and benzoic acid was also successful, as was the use of other garnet-type electrolytes such as Li5+xBaxLa3-xTa2O12 (x = 0, 0.5, 1). In all cases, the garnets with lower Li content showed a higher percent completion of the exchange reaction. The proton conduction in ion-exchanged Li5-yHyLa3Nb2O12 was also confirmed. For Li-ion batteries, the garnet-type Li5La3Nb2O12 was modified by doping with low levels of vanadium to increase density and Li ion conductivity. Various methods were employed to characterize the materials including powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), 7Li nuclear magnetic resonance (Li-NMR), and AC electrochemical impedance.

description: The vision of augmenting computing capabilities of mobile devices, especially smartphones with least cost is likely transforming to reality leveraging cloud computing. Cloud exploitation by mobile devices breeds a new research domain called Mobile Cloud Computing (MCC). However, issues like portability and interoperability should be addressed for mobile augmentation which is a non-trivial task using component-based approaches. Service Oriented Architecture (SOA) is a promising design philosophy embraced by mobile computing and cloud computing communities to stimulate portable, complex application using prefabricated building blocks called Services. Utilizing distant cloud resources to host and run Services is hampered by long WAN latency. Exploiting mobile devices in vicinity alleviates long WAN latency, while creates new set of issues like Service publishing and discovery as well as client-server security, reliability, and Service availability. In this paper, we propose a market-oriented architecture based on SOA to stimulate publishing, discovering, and hosting Services on nearby mobiles, which reduces long WAN latency and creates a business opportunity that encourages mobile owners to embrace Service hosting. Group of mobile phones simulate a nearby cloud computing platform. We create new role of \textit{Service host} by enabling unskilled mobile owners/users to host Services developed by skilled developers. Evidently, Service availability, reliability, and Service-oriented mobile application portability will increase towards green ubiquitous computing in our mobile cloud infrastructure.

description: This thesis applies a combination of process integration tools and mathematical optimization techniques to investigate opportunities to improve surface efficiencies in steam assisted gravity drainage (SAGD) of oil sands operations. The goal of the thesis is to design a distributed effluent treatment system based on the concept of process integration and model this system using mathematical programming methods to minimize cost and energy consumption. Different combinations of water treatment units and steam generation options in SAGD operations are assessed and the tradeoffs between cost, energy, water and GHG emissions within and across these combinations are explored. The results of the thesis show that there are potential cost and electricity savings of up to 19.5% and 12% respectively in the water treatment system of SAGD operations. Interesting tradeoffs have been identified between cost, energy and water which can help oil sands operators make informed decisions about investments in which water treatment technologies for SAGD operations.

description: The Carnegie Hubble Program (CHP) is designed to improve the extragalactic distance scale using data from the post-cryogenic era of Spitzer. The ultimate goal is a determination of the Hubble constant to an accuracy of 2%. This paper is the first in a series on the Cepheid population of the Large Magellanic Cloud, and focusses on the period-luminosity relations (Leavitt laws) that will be used, in conjunction with observations of Milky Way Cepheids, to set the slope and zero--point of the Cepheid distance scale in the mid-infrared. To this end, we have obtained uniformly-sampled light curves for 85 LMC Cepheids, having periods between 6 and 140 days. Period-luminosity and period-color relations are presented in the 3.6 μm and 4.5μm bands. We demonstrate that the 3.6 μm band is a superb distance indicator. The cyclical variation of the [3.6]-[4.5] color has been measured for the first time. We attribute the amplitude and phase of the color curves to the dissociation and recombination of CO molecules in the Cepheid's atmosphere. The CO affects only the 4.5 μm flux making it a potential metallicity indicator.

description: O caso da implantação da televisão digital terrestre (TVD), no Brasil, é paradigmático para o estudo das políticas de comunicação no país. Tendo em vista o atraso histórico do mercado midiático nacional, marcado pela concentração, privilégios político-partidários, falta de controle público dos processos de publicização e ausência de um sistema não-comercial paralelo com força junto ao público, estes problemas deveriam ser atacados justamente neste momento, de transição tecnológica. Como um conjunto de tópicos essenciais ao funcionamento televisivo, envolvendo concessões, equipamento e conteúdos, terão que ser re-regulamentados, na passagem para o digital, há um motivo claramente provocador da rediscussão da TV brasileira. No entanto, isto não aconteceu, nem há perspectiva de que venha a ocorrer, apesar do Brasil ser governado por um partido historicamente identificado com o espectro de esquerda, o PT. (...)

description: Transition from pediatric to adult care is challenging for patients with complex, chronic illnesses such as type 1 diabetes mellitus. To optimize successful transition of care, providers put great efforts into preparing patients for the change. This thesis evaluated the use of videos for patient decision-making in general and one video in particular that was designed to facilitate transition of care. The scoping review demonstrated that there is a vast amount of published data, which show that videos are effective in helping patients make decisions. The focus group study affirmed that patients appreciate the incorporation of a video in their transition preparation. These participants also noted that the process of transition required then to deal with complex emotional ambiguity as well as navigate logistic challenges. Video resources, which may be particularly useful to prepare in youth and young adults for important junctions in care, are valuable tools that should continue to be developed and refined.

description: Childhood obesity is a significant health problem potentially influenced crime. This study employed secondary analysis of cross-sectional data using Geographic Information Systems for spatial comparison and logistic regression for statistical analysis. This was done to investigate the association between obesity, as measured by Body Mass Index of preschool children, and distance to the nearest instance of different categories of crime. Three covariates were included in the study: median family income, proportion of the population who self-identified as visible minorities, and straight-line distance from the child’s postal code to the closest park or green space. Of the eight categories of crime studied, three categories of person crime (commercial robbery, street robbery and other violence) and one category of property crime (theft of vehicle) predicted childhood obesity. This research is unique, as it separated crime into eight categories for analysis, and measured the straight-line distance to crime, rather than using neighbourhood boundaries.
Spatio-temporal spectral analysis of a forced cylinder wake

description: The wake of a circular cylinder performing rotary oscillations is studied using hydrodynamic tunnel experiments at $Re=100$. Two-dimensional particle image velocimetry on the mid-plane perpendicular to the axis of cylinder is used to characterize the spatial development of the flow and its stability properties. The lock-in phenomenon that determines the boundaries between regions of the forcing parameter space were the wake is globally unstable or convectively unstable is scrutinized using the experimental data. A novel method based on the analysis of power density spectra of the flow allows us to give a detailed description of the forced wake, shedding light on the energy distribution in the different frequency components and in particular on a cascade-like mechanism evidenced for a high amplitude of the forcing oscillation. In addition, a calculation of the drag from the velocity field is performed, allowing us to relate the resulting force on the body to the wake properties.

Obrigações de transporte por Operadores de Redes de Comunicações Electrónicas: implicações para a Televisão Digital Terrestre

description: A assunção do pluralismo e da diversidade como objectivos de interesse geral legitima a imposição de obrigações de transporte, abreviadamente designadas por «must carry», aos operadores de redes de comunicações electrónicas. Todavia, e atendendo ao princípio de não discriminação entre empresas que disponibilizem redes e serviços de comunicações electrónicas deverse-á assegurar que o futuro modelo de desenvolvimento da televisão digital terrestre (tdt) não imponha um regime de «must carry» penalizante para a rede tdt se comparado com as obrigações impostas e exigidas às redes de distribuição de serviços de televisão por cabo e satélite.

description: The cerebellum has a simple anatomy and a comparatively small number of neuronal classes connected by clearly defined excitatory and inhibitory projections. The cerebellum is thus an ideal area to study signal processing in neurons and how this behaviour contributes to overall circuit function. A key factor in how the postsynaptic machinery of a neuron converts the information it receives into an output is determined by their intrinsic level of excitability, which in turn determines the pattern or frequency of nerve impulse (spike) discharge. The intrinsic excitability of neurons is determined by the complement of ion channels expressed in the membrane. A low voltage-gated potassium channel of the Kv4 family that is important to regulating spike output in numerous CNS cells is highly expressed in granule cells. The Kv4 channels and low voltage-gated calcium channels of the Cav3 family are known to interact with each other in stellate cells of the cerebellum, whereby the influx of calcium ions enhances the efflux of potassium ions to reduce cell excitability. Thus, any change in the degree of this interaction can fine-tune the role of the Cav3-Kv4 complex in modifying membrane excitability and signal processing via Kv4 channels. This PhD project investigated the hypothesis that the differential expression of a Cav3-Kv4 channel complex and resulting Kv4 availability regulates granule cell excitability, spike output, and learning across the cerebellar lobules. This study used in vitro slices of rat cerebellum to conduct immunocytochemistry and electrophysiological voltage- and current-clamp recordings in the granule cells. Indeed, using immunocytochemistry, this study uncovered differential expression of the Cav3-Kv4 complex across the cerebellar lobules. The electrophysiology work also uncovered key differences in the postsynaptic expression and activity of the Cav3-Kv4 complex between anterior and posterior cerebellum that shapes the processing of mossy fibre input by granule cells. The synaptic plasticity data also revealed a novel NMDAR-mGluR-ERK-Kv4 interplay in cerebellar granule cells that functions to regulate postsynaptic excitability and synaptic responses to mossy fiber input. Overall, this study advances our understanding of the ionic mechanisms that underlie differential signal processing across cerebellar lobules.

description: O estudo da imprensa local e regional (ILR) em Portugal está numa fase rudimentar. Pelo que se conhece dos poucos estudos até agora realizados pode, contudo, afirmar-se que as actuais características do sector são inversamente proporcionais à importância que este tipo de publicações pode – e deve – assumir nas comunidades locais e regionais. Esses estudos evidenciam, de resto, a apetência dos leitores por este tipo de jornais. A clivagem que separa o actual estado do sector da sua importância tem uma consequência ponderosa: sem bons jornais, as comunidades locais e regionais ficam tendencialmente amputadas de boa “informação de proximidade”, uma das mais distintivas características da imprensa local e regional.
