Filter bank multi‐carrier (FBMC) modulation, as a potential candidate for physical data communication in the fifth generation (5G) wireless networks, has been widely investigated. This chapter focuses on the spectral efficiency analysis of FBMC‐based cognitive radio (CR) systems, and spectral efficiency comparison is conducted with another three types of multi‐carrier modulations: orthogonal frequency division multiplexing (OFDM), generalized frequency division multiplexing (GFDM), and universal‐filtered multi‐carrier (UFMC). In order to well evaluate and compare the spectral efficiency, we propose two resource allocation (RA) algorithms for single‐cell and two‐cell CR systems, respectively. In the single‐cell system, the RA algorithm is divided into two sequential steps, which incorporate subcarrier assignment and power allocation. In the two‐cell system, a noncooperative game is formulated and the multiple access channel (MAC) technique assists to solve the RA problem. The channel state information (CSI) between CR users and licensed users cannot be precisely known in practice, and thus, an estimated CSI is considered by defining a prescribed outage probability of licensed systems. Numerical results show that FBMC can achieve the highest channel capacity compared with another three waveforms.

Electromagnetic materials have both civilian and defence applications, such as novel antenna designs and protection against high power transients in densely packed printed circuits. For certain applications, the materials may be required to have special frequency response or polarization response to meet the component or system specifications. An in-depth understanding of the responses of materials to electromagnetic waves may even enable us to design and fabricate materials with properties not found in nature.This book constitutes the proceedings of the Symposium on Electromagnetic Materials,

The work analyses the complex relationship between mental illnesses and curative medicine in the writings of E.T.A. Hoffmann, highlighting problems deriving from unsuitable practices, and shedding light on the overwhelming, asymmetric relationship between doctor/patient, man/woman. The work analyses the doubling phenomena arising from the diaries, which Hoffmann overcame determined not to fall into madness; moreover, the author highlights Hofmmann's qualities as a man and a scholar, attentive to the limits of therapies, questioning doctors without understanding. The author summarises Hoffmann's ideas on the libertarian approach to illness, which includes the acceptance of the patient in their whole being, and presents his idea of therapy consisting of interpersonal dialogue and of listening to a story which reflects a similar case. The author also suggests the novelty of the "talking cure" method ante litteram, which was then successfully adopted by psychoanalysis: a method full of ideas, fruitful for literature, from Poe to Schnitzler, and for cinema, from Hitchcock to Kubrick.

Menção honrosa Prêmio ABEU 2021 – categoria Tradução. Benjamin Franklin (1706-1790) é um dos mais conhecidos personagens da história da ciência. Embora seja famoso por conta do experimento da pipa em meio a uma tempestade – uma anedota bastante controversa, aliás –, Franklin foi um pensador muito mais abrangente. Suas ideias acerca dos fenômenos elétricos buscaram responder às principais lacunas da eletricidade no século XVIII, cobrindo desde a eletrização dos corpos até a formação de grandes temporais com raios e trovões. Franklin abordou também outras questões em seus textos sobre o mundo natural, incluindo a natureza e comportamento da luz. Neste livro, apresento traduções de seis cartas escritas por ele entre 1747 e 1752 – período em que foi mais ativo na filosofia natural – e de um pequeno ensaio sobre a luz, publicado no final da vida, em 1788. A partir disso, o leitor terá acesso direto ao pensamento de Franklin, aos termos que utilizou e às suas explicações para os mais diversos fenômenos da eletricidade e da luz. Esta é a primeira vez que textos de Franklin são traduzidos integralmente para o português brasileiro. Espero que a leitura seja produtiva e que a filosofia natural de Franklin possa ser conhecida em toda sua dimensão e importância.
