Programmable Sequential 4D Actuation in Multistable Kirigami Metamaterials

Advanced Science, EarlyView.
This study presents a modular kirigami metamaterial framework enabling programmable multistability and sequential 4D actuation. By coupling geometry‐controlled multistability with material‐dependent recovery kinetics, spatiotemporal deformation can be precisely programmed.

Multi‐Technique Integration Identifies O‐GlcNAc Transferase in Fibroblast‐Like Synoviocytes as a Therapeutic Target for Rheumatoid Arthritis

Advanced Science, EarlyView.
AI‑guided single‑cell transcriptomics identifies OGT as a key regulator enriched in rheumatoid arthritis fibroblast‑like synoviocytes (RA‐FLSs). Inflammatory stimuli activate the OGT–SAP130 axis, which modulates the H3K27ac/H3K27me3 balance and epigenetically silences BTG2, promoting aggressive transformation of RA‑FLSs.

Rotating Stall Region of Water-Jet Pump

Transactions of FAMENA, 2014
There is a rotating stall region, which is the so-called unstable head curve when water jet is operated. This region should be usually avoided because of the risk of instabilities during the pump starting and operation. Experimental and numerical research on the relation between the instability in the head curve and the magnitude of unsteady hydraulic ...
