Militant Design Research: A Proposal to Politicize Design Knowledge-making

open access: yesDiseña, 2023
This work reflects on how design can engage in emancipatory processes of knowledge-making through Militant Design Research. The argument draws on the work of scholars who are engaged in counter-hegemonic design research and practice, and questions the ...

A Complementary Ring Mixer Driven by a Single-Ended LO in 22-nm FD-SOI CMOS for K and Ka-Bands

open access: yesIEEE Open Journal of Circuits and Systems, 2021
This article presents a double-balanced up-conversion ring mixer based on complementary switches operating at millimeter-wave frequencies. Complementary-switching relieves the mixer from the need for a differential Local-Oscillator (LO) signal ...

Mesenchymal stromal cells for the prophylaxis and treatment of graft-versus-host disease—a meta-analysis

open access: yesStem Cell Research & Therapy, 2020
Background Graft-versus-host disease (GvHD) is the main life-threatening complication of allogeneic hematopoietic stem cell transplantation (HSCT). Thirty to 80% of GvHD patients do not respond to first-line treatment and a second-line treatment is not ...

An efficient 70 GHz divide‐by‐4 CMOS frequency divider employing low threshold devices

open access: yesElectronics Letters, 2021
The idea to use a lower threshold, but slightly slower transistor over the fastest transistor type for large‐signal circuits is presented with experimental verification for a compact divide‐by‐4 true single phase clock (TSPC) frequency divider.
