Abstract:
We show that, for monotone graph map f, all the ω-limit sets are finite whenever f has periodic point and for monotone dendrite map, any infinite ω-limit set does not contain periodic points. As a consequence, monotone graph and dendrite maps have no Li–Yorke pairs. However, we built a homeomorphism on a dendroid with a scrambled set having nonempty interior.

Abstract:
Successive Tremadocian planktic dendroid graptolite assemblages from continental slope sequences in Quebec can be correlated with North American platform biozonations on the basis of conodonts. Anisograptid-bearing (Assemblage 2), middle Tremadocian "Matane faunas" are associated with Early Ordovician Rossodus manitouensis Zone (new designation) conodonts. Younger middle Tremadocian faunas with adelograptids (Assemblage 3) are no younger than the Rossodus manitouensis Zone. Key dendroid evolutionary–immigration events take place within the lower conodont Fauna B interval. Rooted dendroids near Cap des Rosiers, Quebec, and in eastern New York State occur with lower Fauna B conodonts and the trilobites Pareuloma and Borthaspidella. However, the earliest Tremadocian (and earliest Ordovician) dendroid immigration event, represented by the local lowest occurrence of faunas with Dictyonema flabelliforme s.l. at localities in western Newfoundland, eastern New York State, Norway, and eastern China, also lies within the lower Fauna B interval. Finally, the lowest occurrence of key Assemblage 2 dendroid taxa falls within the lower Fauna B interval at the latter localities.The Rossodus manitouensis Zone is proposed as a new designation for a biostratigraphic unit that is appropriate for North American marginal and open shelf sequences. This zone is approximately equivalent to the "Loxodus bransoni Interval" of other authors and is characterized by Fauna C conodonts. Newly described taxa include Rossodus? highgatensis n. sp., Scolopodus? praecornuformis n. sp., and Variabiloconus n. gen.

Often for understanding a structure, other closely related structures with the former are associated. An example of this is the study of hyperspaces. In this paper, we give necessary and sufficient conditions for the existence of finitely-dimensional maximal free cells in the hyperspace C(G) of a dendrite G; then, we give necessary and sufficient conditions so that the aforementioned result can be applied when G is a dendroid. Furthermore, we prove that the arc is the unique arcwise connected, compact, and metric space X for which the anchored hyperspace Cp(X) is an arc for some p∈X.

Abstract:
Gap junctions are known to be important for many network functions such as synchronization of activity and the generation of waves and oscillations. Gap junctions have also been proposed to be essential for the generation of early embryonic activity. We have previously shown that the amplitude of electrical signals propagating across gap-junctionally coupled passive cables is maximized at a unique diameter. This suggests that threshold-dependent signals may propagate through gap junctions for a finite range of diameters around this optimal value. Here we examine the diameter dependence of action potential propagation across model networks of dendro-dendritically coupled neurons. The neurons in these models have passive soma and dendrites and an action potential-generating axon. We show that propagation of action potentials across gap junctions occurs only over a finite range of dendritic diameters and that propagation delay depends on this diameter. Additionally, in networks of gap-junctionally coupled neurons, rhythmic activity can emerge when closed loops (re-entrant paths) occur but again only for a finite range of dendrite diameters. The frequency of such rhythmic activity depends on the length of the path and the dendrite diameter. For large networks of randomly coupled neurons, we find that the re-entrant paths that underlie rhythmic activity also depend on dendrite diameter. These results underline the potential importance of dendrite diameter as a determinant of network activity in gap-junctionally coupled networks, such as network rhythms that are observed during early nervous system development.

Abstract:
The thermal metallurgical modeling of alloying aluminum redistribution was further developed through couple of heat transfer model, dendrite selection model, multicomponent dendrtie grwoth model and nonequilibrium solidification model during three-dimensional nickel-based single-crystal superalloy weld pool solidification over a wide range of welding conditions (laser power, welding speed and welding configuration) to facilitate understanding of solidification cracking phenomena. It is indicated that the welding configuration plays more important role than heat input in aluminum redistribution. The bimodal distribution of solid aluminum concentration along the solid/liquid interface is crystallographically symmetrical about the weld pool centerline for (001) and [100] welding configuration, while the distribution of solid aluminum concentration along the solid/liquid interface is crystallographically asymmetrical throughout the weld pool for (001) and [110] welding configuration. The size of vulnerable [100] dendrite growth region is beneficially suppressed in favor of epitaxial [001] dendrite growth region through optimum low heat input (low laser power and high welding speed) to facilitate single-crystal dendrite growth for successful crack-free weld at the expense of shallow weld pool geometry. The overall aluminum concentration in (001) and [100] welding configuration is significantly smaller than that of (001) and [110] welding configuration regardless of heat input. Severe aluminum enrichment is confined to [100] dendrite growth region where is more susceptible to solidification cracking. Heat input and welding configuration are optimized in order to minimize the solidification cracking susceptibility and improve microstructure stability. The relationship between welding conditions and alloying aluminum redistribution are established for solidification cracking susceptibility evaluation. The higher heat input is used, the more aluminum enrichment is monotonically incurred by diffusion with considerable increase of metallurgical driving forces for morphology instability and microstructure anomalies to deteriorate weldability and vice versa. The mechanism of asymmetrical solidification cracking because of crystallography-dependent alloying redistribution is proposed. The theoretical predictions agree well with the experiment results. Moreover, the useful modeling is also applicable to other single-crystal superalloys with similar metallurgical properties during laser welding or laser cladding.

Abstract:
Dendric words are infinite words that are defined in terms of extension graphs. These are bipartite graphs that describe the left and right extensions of factors. Dendric words are such that all their extension graphs are trees. They are also called tree words. This class of words includes classical families of words such as Sturmian words, codings of interval exchanges, or else, Arnoux–Rauzy words. We investigate here the properties of substitutive dendric words and prove some rigidity properties, that is, algebraic properties on the set of substitutions that fix a dendric word. We also prove that aperiodic minimal dendric subshifts (generated by dendric words) cannot have rational topological eigenvalues, and thus, cannot be generated by constant length substitutions.

Abstract:
During the last century the nervous system has been mainly studied from a reductionistic approach, based on the hypothesis that understanding in depth single neurons or limited neuronal populations would lead to general conclusions on brain function. However, to what extent anatomical details of single neurons can affect the wiring of the networks they form is a largely overlooked question. Intellectual disability provides an excellent opportunity to explore the relevance of fine structural details, because many disorders show specific architectural alterations that correlate with cognitive performance. In this Thesis, I aimed to study how the network topology of neuronal circuits is affected by dendritic architectural features in a mouse model of intellectual disability, namely Down's syndrome, and upon the rewiring effect of pro-cognitive treatment. I did so from three points of view: 1. The exploration of a 2D minimal computational model of cortical layer II/III parameterized by experimental data on dendritic tree architecture of healthy mice and two Down syndrome mouse models 2. The study of within-region morphological variations of hippocampal CA1 pyramidal neurons and their dependency of spatial embedding and cellularity in healthy mice and a Down syndrome mouse model. 3. The development of an experimental and computational framework for whole brain multiscale assessment and reconstruction. My work revealed that the dendritic tree architecture and the distribution of synaptic contacts have significant implications on how optimal single neurons are for information processing efficiency and storage capacity, and that those single-neuron features permeate to the network level, determining the computational capacities of neural ensembles. Also, I found position-dependent neuromorphological inhomogeneities in CA1 pyramids along with variations of neuronal cell density, suggesting that intrinsic properties of CA1 can vary across its extension. Those inhomogeneities were different in healthy and TgDyrk1A mice, possibly affecting emergent functional aspects. In my Thesis I faced challenges to bridge structure and function and to study morphological inhomogeneities at different scale (single cell and cell population). To solve xii those challenges, I developed computational methods for 3D mapping cellular population and dendritic density and assessed their validity. I also developed a computational modeling framework that allows the instantiation of multi-scale biologically realistic networks. Finally, I optimized the CLARITY whole-brain clearing technique and developed a pipeline to apply our population-based analysis and multi-scale modeling methods to the structural interrogation of whole brains, and to study the implications of the neuronal morphospace on the topology of neuronal circuitry.
Durant l’últim segle, el sistema nerviós s’ha estudiat des d’un punt de vista reduccionista, basant-se en la hipòtesi que entendre en profunditat neurones individuals o fraccions petites de poblacions neuronals portaria a conclusions generals sobre la funció del cervell. De totes maneres, fins a quin punt detalls anatòmics de neurones individuals poden afectar la connectivitat de les xarxes que formen, és una qüestió que en gran part s’ha passat per alt. Les discapacitats intel·lectuals proporcionen una oportunitat excel·lent per explorar la rellevància de detalls estructurals, perquè molts trastorns cognitius mostren alteracions arquitectòniques específiques que correlacionen amb habilitats cognitives. En aquesta Tesi, pretenia estudiar com la topologia dels circuits neuronals és afectada per característiques arquitectòniques en un model murí de discapacitat intel·lectual, en concret de síndrome de Down, i per tractaments pro-cognitius amb efectes de remodel·lació de la xarxa. Ho he fet des de tres punts de vista: 1. L’exploració d’un model computacional 2D mínim de la capa cortical II/III parametritzat amb dades experimentals d’arquitectura dendrítica ens els nostres models de síndrome de Down. 2. L’estudi de neurones individuals, la seva diversitat i propietats morfològiques d’escala mesoscòpica en el model murí TgDyrk1A de síndrome de Down. 3. El desenvolupament d’un marc experimental i computacional per a l’estudi del problema des d’una perspectiva multi-escala. La meva feina ha mostrat que l’arquitectura dendrítica i la distribució de contactes sinàptics tenen implicacions significatives en l’optimalitat de neurones individuals per a l’eficiència en el processat d’informació i per a la capacitat d’emmagatzemar memòries, i que aquestes dues quantitats permeen al nivell de xarxa, determinant les capacitats computacionals de conjunts de neurones. També, he trobat variacions neuromorfològiques a CA1 dependents de la posició en neurones piramidals, acompanyades per variacions en densitat cel·lular, apuntat que propietats intrínseques de CA1 poden variar al llarg de la seva extensió. Aquestes inhomogeneitats eren diferents en ratolins sans i TgDyrk1A, possiblement tenint efectes en aspectes funcionals emergents concrets. xiv En la meva Tesi he afrontat reptes en lligar estructura i funció i en l’estudi de les inhomogeneïtats morfològiques en múltiples escales (de cèl·lula individual i de poblacions). Per a assolir aquests reptes, he desenvolupat mètodes computacionals per al mapejat 3D de poblacions cel·lulars i de densitats dendrítiques i he avaluat la seva validesa. També he desenvolupat un marc de modelització que permet l’instanciació multi-escala de xarxes neuronals biològicament realistes. Finalment, he optimitzat la tècnica de clarejat de cervell sencer CLARITY i he desenvolupat un pipeline per a aplicar les nostres eines d’anàlisi de poblacions i els mètodes multi-escala de model·lizatió per a l’anàlisi estructural de cervells sencers, i per a l’estudi de les implicacions del morfoespai neuronal en la topologia de la circuiteria neuronal.

A sincroniza??o neuronal surge de uma intera??o cooperativa de v?rios tipos celulares atrav?s de excita??o e inibi??o. Os mecanismos por tr?s desse tipo de coordena??o neuronal s?o, provavelmente, os mais din?micos entre as fun??es cerebrais, dificultando sua compreens?o. Entre os fatores que dificultam o estudo da sincronia, pode-se citar: o vasto n?mero de tipos de celulares, a diversidade de processos sin?pticos, a contribui??o de uma multiplicidade de canais e correntes i?nicas, entre outros. Essa tese tem como objetivo entender o papel de interneur?nios que especificamente inervam o dom?nio distal dos dendritos de c?lulas piramidais do hipocampo e neoc?rtex, na sincroniza??o de neur?nios em suas respectivas redes. A distribui??o de canais i?nicos e receptors sin?pticos em dendritos de c?lulas piramidais ? extremamente anisotr?pica. Assim, interneur?nios que inervam dom?nios proximais e distais dos dendritos causam efeitos distintos na c?lula alvo quando ativados. Por exemplo, por??es distais dos dendritos cont?m em abund?ncia um dos principais canais marcapassos em neur?nios: o canal regulado por nucleot?deo c?clico ativado por hiperpolariza??o. Esses canais produzem uma corrente cati?nica despolarizante (Ih) e tem um papel importante na regula??o da excitabilidade neuronal alterando dramaticamente as propriedades de disparo de neur?nios. Usando modelagem computacional, essa tese mostra como a amplitude de Ih em certos tipos celulares muda a taxa de disparo de um neur?nio, sua sincronia al?m da energia espectral e frequ?ncia de oscila??es. Al?m disso, como a express?o de Ih difere entre regi?es cerebrais, localiza??o e tipos celulares, essa tese, fazendo o uso de patch clamp, explora como Ih difere ao longo do eixo dorsoventral do hipocampo em c?lulas oriens-lacunosum moleculare (OLM), que s?o os principais interneur?nios que inervam dendritos distais dessa regi?o. Ademais, estudou-se aqui as c?lulas Martinotti, interneur?nios que inervam os dendritos distais do neoc?rtex. Nesse estudo, mostrou-se como uma popula??o definida de interneur?nios pode ser manipulada com o objetivo de controlar e coordenar o disparo de c?lulas piramidais. Ao fornecer inibi??o com energia e frequ?ncia adequada, as c?lulas Martinotti afetam especificamente um ?nico tipo de c?lula piramidal. Usando optogen?tica para ativar/desativar popula??es de c?lulas Martinotti, ? poss?vel gerar potenciais de a??o rebote em c?lulas piramidais quando alinhadas temporalmente. Os potenciais de a??o rebote, por sua vez, s?o resultado de uma forte inibi??o produzida pelas c?lulas Martinotti, o que faz com que esses esses interneur?nios possam resetar o disparo de c?lulas piramidais. De forma geral, c?lulas Martinotti e c?lulas OLM mostram similaridades surpreendentes em propriedades morfol?gicas, neuroqu?micas e eletrofisiol?gicas. Especialmente, suas longas proje??es axonais para camadas superiores assim como seus modos de disparo lentos, com baixos limiares e acomodativos tornam esses neur?nios singulares em suas capacidades de sincronizar os circuitos nos quais est?o inseridos.
Synchronization among neurons arises from the cooperative interaction of various cell types through excitation and inhibition. The mechanisms behind this type of neuronal orchestration are as versatile as almost no other coordination task in the brain, making its comprehension heavily challenging. Among many others, the high number of involved cell types, the diversity of synaptic processes as well as the contribution of a multitude of ion channels and currents span the plurality of neuronal synchronization mechanisms in our brains. Focusing on two brain areas, the hippocampus and the neocortex, this thesis aims to understand the role of distal dendritetargeting interneurons in shaping pyramidal cell activity and the timing of their action potentials. The distribution of ion channels and synaptic receptors in pyramidal cell dendrites is extremely anisotropic. Thus, interneurons innervating the proximal or distal areas of the dendrites cause different effects in the target cell when activated. For example, the distal portions of the pyramidal cell dendrites contain one of the most prominent pacemaker channels: the hyperpolarizationactivated cyclic nucleotide-gated channels. These channels produce a cationic depolarizing current (Ih) and play an essential role in the regulation of neuronal excitability. Using computational modeling, this thesis shows how the amount of Ih in certain cell types determines their spike rate, synchrony as well as power and frequency of ongoing network oscillations. Moreover, since Ih differs between brain regions as well as cell types and location, this thesis electrophysiologically explores how Ih differs along the dorsoventral axis of hippocampus in oriens-lacunosum moleculare (OLM) cells, the main distal dendrite-targeting interneurons of that region. Utilizing the main distal dendrite-targeting interneuron of the neocortex, the Martinotti cell, this thesis also shows how a defined population of interneurons can be manipulated in order to control and align pyramidal cell firing. By providing the right amount and frequency of inhibition, Martinotti cells are able to synchronize trains of subtype-specific pyramidal cells. Using optogenetic approaches to activate/inactivate populations of Martinotti cells, these dendrite-targeting interneurons are shown to trigger rebound action potentials in pyramidal cells when temporally aligned. The rebound action potentials in turn are the result of strong inhibition by Martinotti cells, giving these distal dendrite-targeting interneurons the power to reset pyramidal cell firing. Overall, Martinotti cells and OLM cells show quite striking similarities in morphological, neurochemical and electrophysiological properties. Especially, their long axonal projections to upper layers as well as their low-threshold, slow spiking fashion and the accommodating firing make these distal dendrite-targeting interneurons so special for neuronal synchronization.

Abstract:
Lithium (Li) dendrite formation compromises the reliability of Li-ion batteries, either because dendrite pieces lose electrical contractor or growing dendrite penetrates the separator and leads to internal short-circuiting. In this paper, a multi-scale computational approach integrating phase-field model and first-principles calculation is proposed to predict the Li dendrite formation at the anode/electrolyte interface of Li-ion batteries. The first-principles calculation is employed to atomically determine the interfacial energy, which is subsequently fed into the phase-field model at the micro-scale. 1D distribution of fields is first analyzed to validate the proposed model. An apparent 2D tree-type Li dendrite, widely observed in experiments during electrodeposition, is produced using the model. Finally, the 2D dendritic evolution under different electrochemical conditions specified by the applied current densities is discussed.

Abstract:
This paper describes the relation between the Secondary Dendrite Arm Spacing (SDAS), Area of Mushy Zone with the Continuous Casting variables in low carbon steels during the solidification process in the mold zone. A Finite Element analysis of the heat flow equation, coupled with the solute distribution model and the dendrite growth model, enables the determination of the Secondary Dendrite Arm Spacing (SDAS). The CONBCAST.FOR program is developed in this work to analyze effects of process variables on the Secondary Dendrite Arm Spacing (SDAS), Area of Mushy Zone and Volume of the Bleed. Effort is also made to find the optimum casting parameters. A new concept is introduced in this work to analyze the relation between the Area of Mushy Zone and Secondary Dendrite Arm Spacing (SDAS) with the Volume of the Bleed. Quantitative work is performed by collecting the square shaped billets at two different process conditions and determined the Secondary Dendrite Arm Spacing and Volume of Bleed to analyze the relationship between SDAS, Area of Mushy zone and Volume of Bleed.

Full text
Abstract:
Liquid sodium is used as the coolant of the fast reactor because of its high thermal conductivity. It is superior as thermal medium in spite of high chemical reactivity with oxygen. In many cases, the combustion starts after forming the dendrite oxides on its reaction surface in oxygen atmosphere. This fact indicates that sodium doesn’t ignite and burn easily unless dendrite oxides are formed. The understanding of the formation mechanism of the dendrite oxides helps us to obtain the optimum handling of leftover non-burning sodium after the accident. However, experimental knowledge to understand the mechanism of combustion is still insufficient. The purpose of this study is to clarify the oxidization behavior of a liquid sodium droplet precisely [1]. The reason why we choose the droplet form is derived from the fact that the reaction surface can be easily observed. The experiment was carried out in a glove box filled with argon gas. A single sodium droplet was made at the tip of the nozzle and preheated at the experimental temperature. The oxidization started by supplying the gas mixture of nitrogen and oxygen. The oxygen concentration of the gas mixture and the initial sodium temperature were adopted as experimental parameters, 4% ∼ 20% O2 and 200°C ∼ 500°C respectively. When the gas mixture was supplied, the droplet surface was covered with a white oxide layer. Gradually, the dendrite oxides appeared on the lower side of the sodium droplet, and the aerosol was generated in the vapor phase area. Then, the dendrite oxides on the surface sank in the droplet and the surface became smooth again. Finally the sodium droplet was encompassed by orange flame. The dendrite oxides were found to grow bigger at the first reaction period. It is suggested that the dendrite oxides have a porous structure and the liquid sodium in the droplet is drawn up to their tips by capillary force. Then the sodium oxidization occurs at the tips. The sodium droplet covered by dendrite oxides was also found to be heated up and the dendrite oxides sank into the droplet due to the high oxygen solubility and be finally burned due to the attainment of its ignition temperature as the second reaction period. The heat generation of oxidization as the first reaction period contributed to the combustion phenomena.
