Randomized preclinical study of machine perfusion in vascularized composite allografts
BJS (British Journal of Surgery), EarlyView., 2020 This study was designed to identify the optimum machine perfusion parameters for preservation of limbs before transplantation, and determine whether this was better than cold storage. Normothermic machine perfusion at a pressure of 70 mmHg (NMP‐70) provided superior preservation to cold storage after transplantation.

COMPUTATIONAL FLUID DYNAMICS STUDY OF A CORIUM POOL IN A CANDU CALANDRIA [PDF]
CNL Nuclear Review, 2017 A self-heating pool of corium may form at the bottom of a CANDU calandria during a postulated severe accident. Computational fluid dynamics has been used to model natural convection in such a pool. The split in heat flow to the top, end shield, and bottom surfaces of the pool and the angular distribution of heat flux toward the main shell were ...

Experimental Research on Formation of Large Mass Debris Bed at Severe Nuclear Accident
Yuanzineng kexue jishu, 2023 In a severe accident, the molten core material enters the lower head with water or the reactor cavity is cooled and forms a debris bed. The types of the debris bed formed under different conditions are different, including loose granular, or agglomerated

Multilayered Digital Microfluidic Chip for Cell‐Based Assays
Advanced Materials Interfaces, EarlyView.A multilayered digital microfluidic (mDMF) chip architecture is introduced to improve throughput and robustness in cell‐based assays. By multilayering electrode components and dielectric layers on glass, this design significantly reduces actuation voltage, maintains reliability, and enables expansion of the operational area with minimum current leakage.

Advanced Science, EarlyView.Perivascular matrix densification promotes the emergence of aberrant endothelial tip cells (ATECs) that invade and persist within fibrotic microenvironments. Using in vivo lineage tracing and a human microvessel model, this study shows that fibrous matrix cues destabilize VE‐cadherin–mediated junctions to gate TGF‐β signaling, inducing a pro ...
