A Micropeptide Component of the OGDH Complex Modulates ATP Production in the TCA Cycle
Advanced Science, EarlyView.This study identified a mitochondrial micropeptide encoded by a non‐canonical open reading frame (alt‐ORF) within the CTSB gene. This micropeptide named APPM (ATP production‐promoting micropeptide) is a novel component of the OGDHc complex in the TCA cycle. APPM localizes to the inner mitochondrial membrane and directly binds to OGDH, the E1 subunit of

From Sensing Mechanisms to System Co‐Design: Graphene‐Based Sensors and Readout Circuits
Advanced Science, EarlyView.This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

Large Tilt Angle Lorentz Force Actuated Micro-Mirror with 3 DOF for Optical Applications
Proceedings, 2017 A versatile MEMS micro-mirror for optical platforms is presented, that operates using Lorentz force for actuation, resulting in low voltage operation. While maintaining below 20 mA drive current, this mirror has a tilting angle of over 50° and 20° around

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.

Fault Tolerance Method and MEMS Mirror Based Barcode Scanning System
, 2007 微機電系統(MEMS)是先進奈米科技的一種，其擁有小尺寸、低功率消耗、低成本等等的優點，因此數以百萬計的基於MEMS技術的裝置已經在全世界被廣泛的使用。在數據採集的應用領域上，傳統的雷射式條碼掃瞄器是使用馬達驅動方式的反射鏡面(多面菱鏡)來引導、改變光的行進方向。如果我們改用以MEMS技術為基礎的掃描鏡面，將可以產生全新的雷射掃瞄器，具有速度快、體積小、更輕且效率比市面上現有的掃描器更好的優勢。 本論文主要是想實現一個基於MEMS掃描面鏡的條碼掃描系統 ...

The Interplay of Curvature, Geometry, and Topology Shapes Tissue Organisation in Epithelial Shells
Advanced Science, EarlyView.Purely geometric 3D Voronoi models predict the organisation of epithelial shells. The interplay of curvature, geometry, and topology enriches the number of pentagons in shells with lower number of cells. Small MDCK cysts and Mouse embryos match the top polygonal configurations in a compactness‐based ranking derived from the Voronoi model. In conclusion,
