Análise de um inversor trifásico a quatro chaves
Eletrônica de Potência, 1997 Neste trabalho é estudado o inversor trifásico a quatro chaves (FSTPI) com ênfase na modulação por largura de pulsos (PWM) com implementação digital. Técnicas de modulação PWM com abordagens vetorial e escalar são aplicadas à estrutura e estabelecida a ...

Molecular Oncology, EarlyView.This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Metodología de diseño aplicada a un sistema fotovoltaico con topología de inductor en derivación
Revista Facultad de Ingeniería Universidad de Antioquia, 2015 Para acondicionar óptimamente la energía proveniente de sistemas Fotovoltaicos a la red eléctrica se utiliza el concepto de módulo CA, el cual permite convertir la energía de CD a CA. Sin embargo, el uso de este esquema presenta una baja calidad en la

Tumor B‐cell infiltration in platinum‐treated advanced muscle‐invasive urothelial carcinoma
Molecular Oncology, EarlyView.Bladder tumors with higher pretreatment memory B‐cell infiltration were linked to longer survival after cisplatin chemotherapy, but not carboplatin. These tumors also showed more organized immune structures (tertiary lymphoid structures) and a shared pro‐inflammatory B‐cell‐rich community, suggesting that memory B cells may help identify patients most ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

FEBS Open Bio, EarlyView.ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.
