1. Watch and Wait, Worth It?
Abstract Background The surgery with total mesorectal excision recommended by R. J. Heald in 1982 is the gold standard. Rectal cancer (RC) surgery has a morbidity rate ranging from 6 to 35%, and it can cause functional issues such as sexual, urinary, and bowel dysfunction in the long term. Neoadjuvant chemoradiotherapy (CRT) has been gaining ground in patie

7. O rádio em busca da sua audiência: rumo a uma escuta diversificada e multiplataforma
Resumo O rádio é um meio condicionado pelas mudanças tecnológicas. Desde as suas origens, tem sido também um espaço de comunicação pública que fomenta a cumplicidade, proximidade e interação pessoal com a sua audiência, que se amplifica agora com as possibilidades oferecidas pelo ambiente digital. Este trabalho descreve uma seleção de iniciativ

9. Measurements of Medium Wave HD Radio Reception in a Dense Urban Region
Abstract This paper presents the results of measurements of medium wave received field strength, HD Radio audio quality and maximum coverage distances in a dense urban region. Analog AM and digital HD Radio signals broadcasting the same content were simultaneously transmitted in São Paulo, the largest city in Brazil. The received signal intensity and the re

10. Phase Noise Effects on Wideband Mobile Radio Channel Sounding
Abstract In this work three wideband mobile radio channel sounding methods are simulated and compared using computational tools. The considered sounders include the traditional STDCC and two other proposed sounding methods that are based on OFDM digital transmission and detection procedures and on matched filtering. The impact of the phase noise introduced b

12. Radio-Wave Propagation Model for UHF Band in Different Climatic Conditions with Dyadic Green’s Function
AbstractThis article proposes a deterministic radio propagation model using dyadic Green's function to predict the value of the electric field. Dyadic is offered as an efficient mathematical tool which has symbolic simplicity and robustness, as well as taking account of the anisotropy of the medium. The proposed model is an important contribution for the UHF
