A new solid boundary treatment algorithm for smoothed particle hydrodynamics [PDF]

, 2011
This paper presents a new solid boundary treatment algorithm for smoothed particle hydrodynamics (SPH). Two types of virtual particles are used to model the solid boundary, and information of the virtual particles can be obtained using enhanced SPH ...

Targeting ANGPTL3 and IL‐33/ST2 Ameliorates Diabetic Kidney Disease by Reducing Lipotoxicity, Alleviating Inflammation and Inhibiting Fibrosis

Advanced Science, EarlyView.
Dual targeting of ANGPTL3 and IL‐33/ST2 attenuates diabetic kidney disease by reprogramming lipid–inflammatory crosstalk. This strategy reduces renal lipotoxicity, suppresses inflammatory activation, and limits fibrotic remodeling, thereby preserving kidney structure and function and highlighting a mechanism‐guided therapeutic approach for metabolic ...

Pathological Mechanism‐Inspired Biomimetic Nano‐Senotherapy for Reversing Experimental Atherosclerosis in ApoE−/− Mice

Advanced Science, EarlyView.
The biomimetic self‐assembly nanomedicine reversing atherosclerosis via senotherapy strategy. ABSTRACT The greatest challenge in atherosclerosis (AS) management lies in achieving lesion reversal, not merely slowing progression. Senescent cell accumulation—driven by continuous generation and apoptotic resistance—perpetuates plaque pathology and ...

A Sprayable Nanoplatform Breaks the Vicious Cycle of Diabetic Wounds via Photoactivated Antioxidant and Drug Delivery

Advanced Science, EarlyView.
A sprayable near‐infrared‐activated nanoplatform incorporating MXene, ZnHCF nanozyme, and deferoxamine efficiently breaks the vicious cycle of diabetic wounds. Upon irradiation, interfacial electron transfer and photothermal effects enhance multi‐enzyme activity, enabling explosive ROS elimination, alleviation of hypoxia, and controlled DFO release ...

Lagrangian meshfree finite difference particle method with variable smoothing length for solving wave equations

Advances in Mechanical Engineering, 2018
In a Lagrangian meshfree particle-based method, the smoothing length determines the size of the support domain for each particle. Since the particle distribution is irregular and uneven in most cases, a fixed smoothing length sometime brings too much or ...

NIR‐II‐Trackable LYTACs Phyto‐Nanotheranostics for Source‐Microenvironment Dual‐Track ROS Regulation in Acute Gouty Arthritis

Advanced Science, EarlyView.
The TPR‐LYTACs nanomaterial offers a dual‐pathway strategy for precise gouty arthritis treatment by targeting and degrading the ROS‐producing enzyme NOX2 inside macrophages while its antioxidant core clears accumulated ROS outside. This “source inhibition and microenvironment scavenging” approach, guided by NIR‐II imaging, effectively controls local ...
