Abstract:
The mesoderm in Drosophila invaginates by a series of characteristic cell shape changes. Mosaics of wild-type cells in an environment of mutant cells incapable of making mesodermal invaginations show that this morphogenetic behaviour does not require interactions between large numbers of cells but that small patches of cells can invaginate independent of their neighbours' behaviour. While the initiation of cell shape change is locally autonomous, the shapes the cells assume are partly determined by the individual cell's environment. Cytoplasmic transplantation experiments show that areas of cells expressing mesodermal genes ectopically at any position in the egg form an invagination. We propose that ventral furrow formation is the consequence of all prospective mesodermal cells independently following their developmental program. Gene expression at the border of the mesoderm is induced by the apposition of mesodermal and non-mesodermal cells.

Abstract:
This study examined the relationship between adolescents' use of texting and their level of identity development, cognitive autonomy, and self-esteem. One hundred and nineteen Utah State University students participated in this study by filling out a questionnaire that included a section designed specifically to learn the texting habits of the participants, and also included sections derived from previously existing measures on identity, autonomy, and self-esteem. The results show statistical significance of age and texting. Participants who were 23 years+ sent significantly less than those participants who were 19-22 years. Areas of gender, identity, and self-esteem were also analyzed. Implications of these findings for future research were also discussed.

Abstract:
On admet communément que les tumeurs proviennent de cellules échappant aux contrôles homéostatiques qui sous-tendent les structures histologiques saines et que le phénotype d’une cellule n’est pas le résultat de processus génétiques et biochimiques déterministes mais la conséquence stochastique de réseaux de régulation intra- et intercellulaires. Ce doctorat vise à étudier quantitativement l’homéostasie phénotypique de populations cellulaires et à présenter une approche à la question fondamentale, mais jusqu’alors jamais étudiée, concernant l’autonomie versus le contrôle collectif du devenir des cellules. Nous avons étudié sur le long terme, par cytométrie de flux et dans des conditions 2D puis 3D, le niveau d’expression de CD24 et CD44 de deux lignées cellulaires de cancer du sein (SUM149-PT et SUM159-PT). Trois phénotypes ont été isolés (CD24-/CD44+, CD24+/CD44+, CD24-/CD44-), ce dernier n’avait pour le moment pas été documenté dans la littérature. Le comportement phénotypique des sous-populations CD44-low et CD44-high a été caractérisé en évaluant leur proportion et en analysant leur spectre de fluorescence. Ainsi nous avons observé des comportements périodiques d’apparition et de disparition de pool de cellules caractéristiques des lignées et une re-diversification des phénotypes pour chacune des sous-population. Seule la population issue de CD24-/CD44- re-diversifiée présente le même équilibre que la population initiale non triée. En 3D, le processus de re-diversification a été observé dans les tumorsphères issues de CD24-/CD44+ et CD24+/CD44+. Les cellules CD24-/CD44- n’ont pas ce potentiel mais survivent néanmoins à l’anoïkis. Ces comportements laissent penser qu’il existe une coordination intercellulaire régulant l’équilibre des proportions phénotypiques. Pour découvrir les règles sociales régissant l’organisation spatiale inter-phénotypique, nous avons mis en place un rapporteur des variations du niveau d’expression endogène des marqueurs d’intérêt et élaboré un modèle théorique d’interactions cellulaires. Ce travail a conforté notre hypothèse selon laquelle il s’établit des règles sociales inter-cellulaires déterminant l’expression phénotypique à l’échelle uni- et pluricellulaire
It is commonly accepted that tumors arise from cells that escape the homeostatic controls which underlie the healthy histological structure and that cell phenotype is not the result of deterministic biochemical and genetic processes, but rather the stochastic and dynamic outcome of multiple intra- and intercellular regulation networks. This PhD aims to quantitatively study the phenotypic homeostasis of the cell populations and to present an approach to the fundamental question, never heretofore studied, regarding the autonomy versus collective control of cell fate. We studied in the long run, using flow cytometry and in 2D and 3D conditions, the level of expression of CD24 and CD44 of two breast cancer cell lines (SUM149-PT and SUM159-PT). Three phenotypes were isolated (CD24-/CD44+, CD24+/CD44+, CD24-/CD44-), the latter had not previously been documented in the literature. The phenotypic behavior of CD44-low and CD44-high subpopulations has been characterized by assessing their proportion and analyzing the fluorescence map. Thereby, we observed both a periodic behavior of appearance and disappearance of pool of cells characteristics of each cell lines and a phenotypic re-diversification for each subpopulation. Only the resulting population derived from CD24-/CD44- provided the same balance as the original unsorted population. 3D re-diversification process was observed in tumorspheres from CD24-/CD44+ and CD24+/CD44+. The cells CD24-/CD44did not have that potential but nonetheless outlived anoikis. These behaviors suggest that there is an inter-cell coordination regulating the balance of phenotypic proportions. To discover the social rules regulating inter-phenotypic spatial organization, we have set up a reporter of the endogenous variations of CD24 and CD44 and developed a theoretical model of cell interactions. This work has confirmed our hypothesis that inter-cellular social rules are determining the phenotypic expression at both the uni- and multicellular scales

Abstract:
Disorders of the autonomic nervous system constitute serious complications of spinal cord injury (SCI) and their treatment is usually highly prioritised by spinal patients. Among these, autonomic dysreflexia and impaired thermoregulation are potentially life threatening conditions and require effective management. Olfactory ensheathing cells (OECs), progenitor cells and polymeric scaffolds have been tested in animal models of SCI and some of them have been considered for clinical trials. However, evaluation of the effect of such interventions on autonomic functions has received only rudimentary attention and would require a more thorough experimental assessment before the methods are utilised in human patients. This thesis tested two potential therapeutic strategies for autonomic dysreflexia and examined disorders of thermoregulatory functions in a rat model of spinal cord transection. Magnitude and duration of autonomic dysreflexia were evaluated with radio telemetry in spinalised animals treated with (i) implants of OECs and olfactory neurosphere-derived cells seeded in poly(lactic co glycolic) porous scaffolds or with (ii) transplants of OECs alone. (iii) Effects of SCI and of OECs on the morphology of sympathetic preganglionic neurons (SPNs; which are involved in pathogenesis of autonomic dysreflexia) stained for NADPH diaphorase were examined. (iv) Doppler ultrasonography and infrared thermography were used to assess responses of tail blood flow and surface temperature to cold. Transplants of OECs alone, but not in combination with olfactory neurosphere-derived cells and polymeric scaffolds, resulted in significantly shortened episodes of autonomic dysreflexia. This may be attributed to the alterations to the morphology of SPNs adjacent to the lesion: a transient increase in the morphometric features of the SPNs was evoked by spinal cord transection and this was further altered by transplantation of OECs. The thesis also showed that local responses of tail blood flow and temperature to cold were not abolished by complete SCI suggesting that temperature homeostasis could still be maintained in response to cold. It is hypothesised that OECs facilitate improved recovery from autonomic dysreflexia through alteration of the morphology of SPNs. Furthermore, it is suggested that the role of the tail in heat conservation can be regulated by mechanisms that are independent of the descendent neural control from supraspinal centres.

The primary function of the heart is to pump blood at a sufficient rate to ensure perfusion of all the organs. This vital task is achieved in large part by controlling the rate of cardiac contractions, which are initiated by cells in the sinoatrial node, the "pacemaker" of the heart. The oscillation rate of these spontaneously active cells is tightly regulated by the sympathetic and parasympathetic branches of the autonomic nervous system. Our understanding of sinoatrial node cell function has been greatly advanced by experimental and modeling efforts that quantitatively describe the numerous ionic currents responsible for the cell's spontaneous depolarization and generation of the action potential. Several models have also explored the effect of sympathetic and parasympathetic activity on specific ion channels and have reproduced the classic slowing and acceleration phenomena. However, a complete model of this interaction does not exist: current models lack the ability to simulate simultaneous sympathetic and parasympathetic activation or to reproduce heart rate dynamics in response to time-varying autonomic inputs. We addressed this need by constructing a bottom-up model of sinoatrial node cell regulation by the autonomic nervous system, with a focus on reproducing the full range of heart rates observed under simultaneous sympathetic and parasympathetic nerve stimulation, as well as the dynamic heart rate response to steps in sympathetic or parasympathetic stimulation rate. In constructing our model, we consolidate a large body of experimental data in a consistent mathematical framework. The model comprises 57 nonlinear coupled ordinary differential equations based on first principles and the current mechanistic understanding of the component reactions, fits well all the experimental data used to build the model, and reproduces high-level features of the system that were not explicitly fit when building the model. The detailed nature of the model also allows numerous conclusions to be drawn about the mechanisms of heart rate control. A better understanding of these mechanisms in health and disease may enable the development of better diagnostics for cardiovascular disease and more targeted drug design. We also identified a number of limitations in the present model that can be refined through further experimental and numerical efforts.

Abstract:
This chapter reviews recent literature on uses, effects, and gratifications of media during emerging adulthood. The authors examine traditional media forms, including television, films, video games, music, and books, and also newer media, such as cell phones, social networking sites, and other Internet use, finding that emerging adults spend more time using media than they spend doing any other activity, with most time being spent on the Internet and listening to music. They also find that exposure to certain types of media content can influence both positive and negative outcomes in emerging adulthood, including aggressive and prosocial behavior, body image, sexual behavior, friendship quality, and academic achievement. The authors show that emerging adults use media to gratify certain needs, key among them entertainment, autonomy, identity, and intimacy needs. The authors discuss areas for future research involving media and emerging adulthood.

Abstract:
The overall characteristics of electric power grid in terms of continuity of the supply and energy quality are of outmost importance for both industrial and civil applications with special attention to the uninterruptible ones. Net congestion problems are becoming more and more frequent boosting the development of small energy generation systems with back-up function. In this field low temperature fuel cells are an interesting solution addressing both environmental and efficiency issues. In the present work the application of Polymer Electrolyte Fuel Cells (PEFC) for an Uninterruptible Power Supply (UPS) system (<1kWe) is analysed by examining different possible technical solutions. This system is composed by a PEFC 1kWe stack, assisted by a set of battery and a supercapacitors pack, and using hydrogen stored into a metal hydride tank. Critical aspects as system start-up, response rapidity and autonomy are addressed to obtain an optimal configuration. Both numerical and experimental analysis have been carried out to characterize component behaviour. Once realized and tested, the system has proved to be able to work as UPS with an autonomy of 6.5 hours, only determined by hydrogen storage capability.

Abstract:
Economic factors together with protection laws and policies pertaining to marine pollution drive research for improved power generation. Fuel cells, being fuel efficient and environmentally friendly, could provide a desirable option and suitable alternative to conventional propulsion systems based on fossil fuels or even nuclear fission. Fuel cells are becoming fast a mature technology and employed in many various other areas. Flexibility of special purpose watercraft, power autonomy and modularity can all benefit from the use of fuel cells. Specifically, proton exchange membrane fuel cells are considered among the most promising options for marine propulsion applications. Switching converters are the common interface intermitted between fuel cells and the load in order to provide a stable regulated voltage. DC-DC converters have been widely used since the advent of semiconductors. These devices are typically adopted to accomplish voltage regulation tasks for a multitude of applications: from renewable energy power-plants to military, medical and transportation systems. Nonetheless voltage regulators exhibit the need for consistent closed- and open-loop control. Most common approaches are PID controllers, sliding mode controllers and artificial neural networks that are considered in this work. An artificial neural network (ANN) is an adaptive, often nonlinear system that learns to perform a functional mapping from data. In our approach, a typical example of a fuel cell, a power converter outfitted with an ANN controller, and a resistive load configuration is investigated. Simulation studies are crucial in power electronics to essentially predict the behavior of the device before any hardware implementation. General requirements, design specification together with control strategies can be iteratively tested using computer simulations. This paper shows the simulation results of the full system behavior, as described above, under dynamic conditions. Initially, an open-loop simulation of the system is performed. Next, an appropriately trained ANN is incorporated to the switching model of the DC-DC converter to perform simulations for validation. Conversely, during design and calibration of the ANN controller, instead of the switching model of the DC-DC converter, a trained ANN equivalent is employed.

Abstract:
Integration of non-dispatchable renewable energy sources such as wind and solar into the grid is challenging due to the stochastic nature of energy sources. Hence, electrical hubs (EH) and virtual power plants that combine non-dispatchable energy sources, energy storage and dispatchable energy sources such as internal combustion generators and micro gas turbines are getting popular. However, designing such energy systems considering the electricity demand of a neighborhood, curtailments for grid interactions and real time pricing (RTP) of the main utility grid (MUG) is a difficult exercise. Seasonal and hourly variation of electricity demand, potential for each non-dispatchable energy source and RTP of MUG needs to be considered when designing the energy system. Representation of dispatch strategy plays a major role in this process where simultaneous optimization of system design and dispatch strategy is required. This study presents a bi-level dispatch strategy based on reinforced learning for simultaneous optimization of system design and operation strategy of an EH. Artificial Neural Network (ANN) was combined with a finite state controller to obtain the operating state of the system. Pareto optimization is conducted considering, lifecycle cost and system autonomy to obtain optimum system design using evolutionary algorithm.

Abstract:
This paper reveals the virtual L7e vehicle, GRAND TWIZY concept for the first time into an conference. The concept is an academic project and is developed within at the “Alternative Propulsion Systems –Electric and Hybrid Vehicles” Laboratory of the “Automotive Engineering” Research Centre, University of Pitesti, Romania. The main objective of the project is minimal costs development of a L7e concept, starting from the RENAULT TWIZY quadricycle and increasing its habitability, versatility and autonomy, similar to the competitors`. The vehicle design is influenced by four elements: the exterior design, legal requirements, the powertrain components and the vehicle components provided by RENAULT TWIZY. To increase the habitability, the body has been modified in transversal direction, keeping the same wheelbase of the vehicle. This solution allows minimal chassis and body transformations, taking over many mechanical components of the front axle, of the rear axle and the electric powertrain and taking as many body parts as possible, especially from the lateral sides of the original RENAULT TWIZY vehicle. The new body has a new anti-rain system for the doors and heating and ventilation system. This allows extending the period of use in rain conditions and low temperatures (winter). For increasing the versatility the passenger seat is placed on the lateral side of the driver. The rear space can be usable for the placement of luggage or the placement of children's seats. The increasing luggage transport space we have created a space modularized in the passenger`s seat place. For the transport of oversized equipment or luggage it was built a folding outer trunk. In order to increase the autonomy and the additional electricity consumption caused by the heating and the ventilation system for the passenger compartment, a new 48 V traction battery with NMC technology (Nickel Manganese Cobalt) is proposed. It contains elements from the Renault ZOE 50 battery, produced by LG Chem. This battery is charged with a bidirectional charger, able to function “Vehicle to Grid” (V2G), both by cable and wireless. The charging system, was built from a charger-inverter assembly, compatible with lithium-ion batteries. In the case of the proposed wireless charging system, the transfer of station and vehicle energy was made trough by means of a magnetic field that circulates between an emitter (coupled to the 230V-50Hz single-phase alternating current) and a receiver mounted on the vehicle (coupled by charger to the 48 V traction battery). In addition, the traction battery is charged with a photovoltaic cell system located on the roof was provided. This solution was favored by the extension of the roof surface caused by the vehicle. To reduce vehicle mass and increase the reliability of the servitude battery, is propose to replace the 12 V battery with AGM lead technology with a Panasonic DLC (Double Layer Capacitor) battery.

Abstract:
Introduction: Lambert-Eaton Myasthenic Syndrome (LEMS) is an ultrarare autoimmune disorder of neuromuscular junction characterized by proximal muscle weakness, arreflexia and autonomic dysfunction due to presynaptic dysfunction caused by autoantibodies against the P/Q-type voltagegated calcium channel with diminished release of acetylcholine. LEMS can occurs as a primary autoimmune disorder or as paraneoplastic disorder with more than half of LEMS cases associated with small cell lung cancer. Objectives: The main objective of this study is described clinical, epidemiological, serological, and neurophysiological findings of a Brazilian cohort with definitive diagnosis of Lambert-Eaton Myasthenic Syndrome (LEMS). Results We identified eight patients with definitive LEMS with a 2:1 male/ female prevalence, all present with proximal muscle weakness with lower limb predominance and the most common autonomic dysfunction were xeropthalmia in 100% of patients, orthostatic hypotension presented in 6 of 9 patients and erectile dysfunction in all male patients. Conclusions: LEMS should always be suspected in patients with proximal muscle weakness associated with autonomic dysfunction and in this Brazilian cohort most cases were seronegative and do not have correlation with small-cell lung cancer in contrast with the current knowledge of disease.
