Programmable Information Processing With Reconfigurable Self‐Contact Variable Stiffness Mechanical Metamaterial

open access: yesAdvanced Science, EarlyView.
Reconfigurable self‐contact variable stiffness metamaterials based on shape memory polymers enable programmable stiffness switching. Static arrays store and encrypt information with immunity to electromagnetic interference, while asymmetric stiffness converts symmetric vibration into directional matter transport.

Sonogenetics Nanomedicine Activates the cGAS‐STING Pathway for Immunotherapy of Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
A HER3‐targeted sonogenetic lipid nanoparticle platform is developed for triple‐negative breast cancer therapy. An AI‐designed miniprotein inhibits HER3 signaling, while TRPV4 and NFAT‐responsive IL‐15 plasmids enable ultrasound‐controlled calcium signaling and cytokine expression. The system induces Ca2+ overload, ROS generation, mitochondrial damage,

A Set-Based Mapping Strategy for Flash-Memory Reliability Enhancement

open access: yes, 2007
隨著快閃記憶體在眾多領域的廣泛應用,可靠性成為了一個關鍵的議題。引發這個研究的動機在於工業界常將具有瑕疵的快閃記憶體「次級化」後售出,但仍需在低成本的考量下保證其產品具有一定的使用壽命。面對此類強烈的需求,我們提出了一套以集合(Set)為主要概念的快閃記憶體管理策略,稱之SFTL,其最大的特色運作時僅需要極少量的資源,如靜態隨機存取記憶體(SRAM)。此外我們也顧及了管理策略的彈性與損耗程度的平均化(Wear-leveling)。我們將所提出的管理策略與目前工業界中許多受歡迎的既存做法相互比較分析 ...

Restores Aβ Clearance by Overcoming PCSK9–LRP1 Dysregulation and TRIB3‐Mediated Autophagy Blockade in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
PCSK9 upregulation in cerebrovascular endothelial cells and microglia destabilizes the Aβ transporter LRP1, while TRIB3‐associated autophagy blockade further limits intracellular Aβ degradation. A RAP‐modified tea‐polyphenol nanoparticle co‐delivers siPCSK9 and siTRIB3 to restore LRP1‐mediated Aβ efflux and autophagy‐dependent degradation, reducing Aβ ...

Intelligent Read Framework With Meta-Learning for NAND Flash Memory Under Process Variation

open access: yesIEEE Access
The storage density of NAND flash memory has significantly increased due to multi-leveling and downscaling technologies. As a side effect of enhanced storage capacity, flash memory becomes vulnerable to circuit-level noise.
