SPICE simulation of quasi-resonant zero-current-switching DC-DC convertors
Electronics Letters, 1990 A simple, topology-independent method is proposed for simulating the responses of open and closed-loop quasiresonant DC-DC convertors operating in the zero-current-switching mode (ZCS-QRC). The method hinges on the substitution of the resonant network and switch assembly, fundamental in the realisation of such systems, by an equivalent circuit which ...

Molecular Oncology, EarlyView.Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Molecular Oncology, EarlyView.Circulating tumor cells (CTCs) and plasma cell‐free DNA (cfDNA) were analyzed to detect ESR1 mutations and methylation in patients with advanced breast cancer. CTC‐derived DNA showed higher sensitivity for mutation detection and revealed complementary genetic and epigenetic alterations, highlighting the added value of CTC analysis for understanding ...
