Cost-effectiveness of brief structured interventions to discontinue long-term benzodiazepine use: an economic analysis alongside a randomised controlled trial [version 1; peer review: 2 approved]

open access: yesHRB Open Research, 2020
Background: In Spain, long-term use of benzodiazepine is prevalent in 7% of the population; however, this longer-term use lacks clinical benefits, costs €90million per year and side-effects further add extra cost through adverse health outcomes.

An On‐Chip Elliptic Bandpass Filter With High Selectivity and High Stopband Attenuation Near the Passband Based on Stacked Series‐Parallel Topology

open access: yesIET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
A high selectivity integrated passive device (IPD) on‐chip bandpass filter is presented. The stacked series‐parallel topology is employed to generate two transmission zeros and a transmission pole to maintain high selectivity and high stopband attenuation near the passband.
