Towards quantum-cascade VECSELs for terahertz heterodyne local oscillators

TL;DR: In this article , a patch-based amplifying metasurface VECSEL with milliwatt output power at 4.6 THz and phase locking at 3.4 THz to a microwave reference using a Schottky diode mixer.

Comparative evaluation of converter-based compensation schemes for VSC systems to achieve full-range active power transfer in very weak grids

TL;DR: In this article , the relationship between active power transfer range and weak grid factors of the generic VSC-grid system is analyzed, and the most effective way to allow the VSC to exchange the rated active power in both directions with the weak grid is presented to extend the operation boundary and avoid voltage collapsing.

TL;DR: In this paper, the performance of the muon reconstruction in the analysis of proton-proton collisions at the LHC was studied in terms of reconstruction and isolation efficiencies and momentum resolutions for different classes of reconstructed muons.

Update on treatment as prevention of HIV illness, death, and transmission: sub-Saharan Africa HIV financing and progress towards the 95–95–95 target

TL;DR: With additional funding and improved efficiency, achieving the 95–95–95 target to diagnose 95% of all HIV-positive individuals, provide antiretroviral therapy (ART) for95% of those diagnosed and achieve viral suppression for 95%" of those treated by 2030 is feasible and the humane pathway towards ending the HIV pandemic.
