A Code‐Invariant QSG–VGA Co‐Design Methodology for Compact CMOS Vector‐Sum Phase Shifters

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
A circuit‐level co‐design methodology for compact vector‐sum phase shifters is presented, combining a code‐invariant common‐gate variable‐gain amplifier (VGA) with a resistorless quadrature signal generator (QSG). By maintaining an almost constant input resistance, explicit resistors are eliminated from the QSG.

Drosophila male genitalia rotation depends on permissive remodeling of the posterior abdomen

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background One of the most characteristic morphogenetic processes in Drosophila is the 360° rotation of the male pupal genital disc. This movement is driven by the myosin Myo1D, whose expression in the genital disc is controlled by the Hox gene Abdominal‐B (Abd‐B).

Enfoque universitario

open access: yes, 2010
Las universidades se han incrementado en el Perú, debido al aumento de la demanda para una educación superior. Sin embargo, la calidad de la educación se ha estancado. Las universidades deben cumplir el papel de formadoras de futuros ciudadanos que contribuyan con la sociedad con el conocimiento adquirido.

Biomarkers of lung congestion and injury in acute heart failure

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 781-789, April 2025.
Abstract Acute heart failure (AHF) classification and management are primarily based on lung congestion and/or hypoperfusion. The quantification of the vascular and tissue lung damage is not standard practice though biomarkers of lung injury may play a relevant role in this context.

Analysis of the usefulness and benefits of ultrafiltration in cardiorenal syndrome: A systematic review

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1194-1202, April 2025.
Abstract Aims Cardiac decompensation in cardiorenal syndrome (CRS) results in systemic congestion usually treated with diuretics. When despite high doses of diuretics, response is poor, ultrafiltration (UF) appears to be a useful and safe technique.
