1. Increasing the Chances of Natural Conception: Opinion Statement from the the Brazilian Federation of Gynecology and Obstetrics Associations - FEBRASGO Committee of Gynecological Endocrinology
Resumo Uma vez que mitos e equívocos sobre a procriação natural se espalham rapidamente na era do fácil acesso à informação e às redes sociais, o aconselhamento adequado sobre a fertilidade natural e a concepção espontânea deve ser encorajado em qualquer tipo de assistência à saúde. Apesar do fato de não haver evidências fortes sobre qualquer

2. Particle swarm optimization in WDM/OCDM networks with physical impairments
In this paper, optimization procedures based on particle swarm optimization (PSO) are investigated, aiming to efficiently solve the optimal resource allocation for signal-to-noise plus interference ratio (SNIR) optimization of optical code paths (OCPs) from wavelength division multiplexing/optical code division multiplexing (WDM/OCDM) considering imperfectio

3. Avalanches e redes complexas no modelo Kinouchi-Copelli / Avalanches and complex networks in Kinouchi-Copelli model
The capacity of a sensory system in efficiently detecting stimuli is usually given by the dynamic range, a simple measure of the range of stimulus intensity over which the network is sensible enough. Many times biological systems exhibit large dynamic ranges, covering many orders of magnitude. There is no easy explanation for that, since individual neurons p

4. Viabilidade de formação de redes espontâneas pessoais de conhecimentos entre docentes de pós-graduação das áreas de Ciência da Informação e Administração da UFPB
It deals with information and knowledge as key assets within the organizations, and the prospect of Information Science investigates the properties and behavior of information, the forces that govern the information flow and processing facilities. From this perspective, the objective is to analyze the feasibility of collaborative networks of spontaneous inte

5. Algoritmos RWA para redes ópticas transparentes considerando limitações da camada física / RWA algorithms for optical transparent networks considering physical impairments
With the proliferation of new multimedia services such as VoIP and IP-TV, an increasing demand for high rates of data transfer is being seen. Thus, the demand on the core of the network is continuously growing, so its capacity must increase in the same ratio to provide a reliable service to end users. The Transparent Optical Networks with WDM appears as a so

6. Redes de osciladores dissipativos : o modelo duplicado de Caldeira-Leggett, transferência quase-perfeita de estados e recoerência
In this work we treat firstly what we call the double Caldeira-Leggett model, which consists on the approach to the dynamics of two dissipative harmonic oscillators via Feynman-Vernon theory. We derived and solved the associated master equations in two different situations where i) each oscillator is coupled to its own reservoir and ii) both oscillators are

7. Analise do desenvolvimento das praticas urbanas de lazer relacionadas a produção cultural no periodo nacional-desenvolvimentista a globalização atraves da Teoria da Ação Comunicativa
This doctoral thesis seeks to investigate the practices of urban recreation in Brazil and its development-including the national developmental until globalization, addressing the artistic production of the period, public policies and inclusion of the private sector, with the parameter analysis of the theory of Habermasian communicative action. Second interpr

8. Systemic analysis of noise penalties all-optical network / AnÃlise sistÃmica das penalidades de ruÃdo nas redes Ãpticas transparentes
In this thesis, the routing and wavelength assignment processes are addressed. Besides of considering the network layer resources (number of available wavelengths in a link), the impact of physical layer effects in the transmitted optical signals is analyzed for both processes. The optimization of the wavelength assignment process is obtained by minimizing t

9. SNU: um framework para o desenvolvimento de aplicações voltadas às redes ad-hoc espontâneas / SNU: a framework for the development of applications Striving to networks ad-hoc spontaneous
Dispositivos móveis evoluíram de simples agendas, calendários ou telefones celulares para modernos assistentes pessoais, capazes de armazenar e processar áudio e vídeo em tempo real. Contudo, dar a melhor utilidade a esta tecnologia em nossas tarefas do dia-a-dia ainda é um desafio. A grande variedade de dispositivos, a crescente necessidade de serviç

10. As organizações de suporte suportam ou são suportadas pelas redes interorganizacionais?
The aim of this work is to discuss the actual role played by Public and Para Public institutions (SEBRAE, State and Municipal secretaries, national agencies, departments, public universities, etc.) when supporting interorganizational networks. In order to reach this objective, an empirical research was carried out so that concrete evidences of the management

11. Spontaneous evolution of modularity and network motifs
Biological networks have an inherent simplicity: they are modular with a design that can be separated into units that perform almost independently. Furthermore, they show reuse of recurring patterns termed network motifs. Little is known about the evolutionary origin of these properties. Current models of biological evolution typically produce networks that

12. Formation of geometrically complex lipid nanotube-vesicle networks of higher-order topologies
We present a microelectrofusion method for construction of fluid-state lipid bilayer networks of high geometrical complexity up to fully connected networks with genus = 3 topology. Within networks, self-organizing branching nanotube architectures could be produced where intersections spontaneously arrange themselves into three-way junctions with an angle of
