Protocolos de encaminamiento en redes inalámbricas mesh: un estudio teórico y experimental

Una red inalámbrica mesh o en malla es un subtipo de red ad-hoc en la que los nodos que la forman pueden actuar además como puntos de acceso para otros dispositivos o como pasarelas a otras redes. Para ello se hacen necesarios protocolos que permitan a cada nodo saber cómo enviar datos a cualquier otro nodo de la red, así como informar de nodos nuevos o enlaces rotos. En este trabajo hacemos un repaso del estado del arte en cuanto a dichos protocolos de encaminamiento mesh, describiendo los más relevantes y que poseen implementaciones libres. Además se proporciona un estudio comparativo experimental del rendimiento ofrecido por cuatro de estas implementaciones: Open80211s, B.A.T.M.A.N., Babel y Meshias.

Addictions [Addiction].

What's new in addiction medicine in 2012? The news are presented according three axes: first, in the field of neuroscience, the process of extinction of addiction memories. Then in the clinical field, a reflexion is reported on how to treat addiction in psychiatric hospitals. At last, in the area of teaching, an e-learning development with a virtual patient shows a great interest in addiction psychiatry.

Association of urethral toxicity with dose exposure in combined high-dose-rate brachytherapy and intensity-modulated radiation therapy in intermediate- and high-risk prostate cancer.

INTRODUCTION: To report acute and late toxicities in patients with intermediate- and high-risk prostate cancer treated with combined high-dose-rate brachytherapy (HDR-B) and intensity-modulated radiation therapy (IMRT). MATERIALS AND METHODS: From March 2003 to September 2005, 64 men were treated with a single implant HDR-B with 21 Gy given in three fractions, followed by 50 Gy IMRT along with organ tracking. Median age was 66.1 years, and risk of recurrence was intermediate in 47% of the patients or high in 53% of the patients. Androgen deprivation therapy was received by 69% of the patients. Toxicity was scored according to the CTCAE version 3.0. Median follow-up was 3.1 years. RESULTS: Acute grade 3 genitourinary (GU) toxicity was observed in 7.8% of the patients, and late grades 3 and 4 GU toxicity was observed in 10.9% and 1.6% of the patients. Acute grade 3 gastrointestinal (GI) toxicity was experienced by 1.6% of the patients, and late grade 3 GI toxicity was absent. The urethral V(120) (urethral volume receiving > or =120% of the prescribed HDR-B dose) was associated with acute (P=.047) and late > or = grade 2 GU toxicities (P=.049). CONCLUSIONS: Late grades 3 and 4GU toxicity occurred in 10.9% and 1.6% of the patients after HDR-B followed by IMRT in association with the irradiated urethral volume. The impact of V(120) on GU toxicity should be validated in further studies.
