Variable DC voltage based reactive power enhancement scheme for MMC‐STATCOM
Constrained by the AC voltage amplitude modulated by a modular multilevel converter‐based static synchronous compensator (MMC‐STATCOM), its reactive power output may be subject to oscillations under grid contingencies, posing a threat to the grid stable ...

Targeting the EpCAM‐AXL axis to overcome drug resistance in lung cancer
Lung cancer cells often evade therapy by hijacking signaling pathways. We reveal that cleaved EpCAM (sEpCAM) stabilizes the oncogenic protein AXL, driving NF‐κB and STAT3‐mediated chemoresistance. This EpCAM‐AXL axis identifies a high‐risk patient subset with poor prognosis.

Loss comparison of 2 and 3-level inverter topologies
This paper investigates semiconductor and DC-link capacitor losses in two two-level and two three-level voltage source inverters. The components of the four inverters are selected to have appropriate voltage and current ratings.

Analysis of DC voltage oscillation mechanism in AC/DC hybrid distribution system
DC voltage oscillation occurs more and more frequently in voltage source converter (VSC)-based AC/DC hybrid distribution system (AC/DC HDS). However, currently, the explanation of the oscillation mechanism is not clear enough.

Engineering IL‐4 resistant proinflammatory human myeloid cells for cancer immunotherapy
We developed a scalable workflow to generate proinflammatory human myeloid cells. CRISPR/Cas9‐edited CD34+ hematopoietic stem and progenitor cells were expanded and differentiated with M‐CSF. Deletion of STAT6 or STAT6/NFKB1 enhanced macrophage proinflammatory gene expression and cytokine secretion in the presence of IL‐4 while maintaining antibody ...

Parallel current-controlled synchronverters for voltage and frequency regulation in weak grids
The emulation of synchronous machines is becoming an attractive solution to provide virtual inertia and voltage support to weak grids and microgrids, representing an alternative to conventional current-injection control strategies.

Vectorial formalism for analysis and design of polyphase synchronous machines [PDF]
A vectorial formalism for analysis and design of polyphase synchronous machines without reluctance and saturation effects is described. We prove the equivalence of such a machine with a set of magnetically independent machines, which are electrically and
