Discrete least square method for nonmatching mesh problems
Choi, Jae-Hoon ; Lee, Byung-Chai ; Sim, Gi-Dong

초록	This research presents a novel algorithm designed to address nonmatching mesh problems. The key feature of the algorithm is its explicit definition of an interface force on nonmatching interfaces. The displacement at the nonmatching mesh is formulated as a function of the interface force, which is determined through the implementation of displacement continuity conditions using the least square method. Notably, this method offers simplicity and robustness, as it eliminates the necessity for integration at the nonmatching mesh. Numerical examples are provided to assess the algorithm’s performance, demonstrating its potential applicability to a wide array of problems involving nonmatching meshes, including domain decomposition and parallel computation.

A Mobile Semantic LiDAR SLAM Processor with AI-based 3D Perception and Spatio-temporal-aware Computing
Jung, Jueun ; Kim, Seungbin ; Seo, Bokyoung ; Jang, Wuyoung ; Lee, Sangho ; Shin, Jeongmin ; Han, Donghyeon ; Lee, Kyuho Jason

초록	A low-power artificial intelligence (AI)-based semantic LiDAR SLAM processor is proposed to expand autonomous driving into emerging mobile robots. It combines point neural network (PNN)-based 3D segmentation with LiDAR SLAM to minimize pose errors due to the lack of perception in previous SLAM. The proposed processor is designed with a heterogeneous multi-core architecture utilizing SIMD and reconfigurable processing elements to fully support the three main operations: k-nearest neighbor (kNN); PNN; and non-linear optimization. It accelerates kNN operations with spherical bin partitioning optimized for the distribution of LiDAR data to eliminate unnecessary search spaces. In addition, the proposed spatio-temporal-aware computing minimizes excessive memory overhead and workload imbalance in kNN and PNN operations. Consequently, fabricated with 28-nm CMOS technology, the processor achieves 8.245 mJ/frame of energy consumption and a maximum performance of 20.7 ms latency, successfully demonstrating real-time semantic LiDAR SLAM system with 99.86% lower power consumption compared to modern CPU+GPU platforms. © 1981-2012 IEEE.

Development of chemical probes for capturing protein arginine kinases
Lee, Shin Hyeon ; Kee, Jung-Min

초록	Protein kinases play a critical role in controlling numerous cellular regulation pathways and signal transduction.1 Protein arginine phosphorylation, one of the relatively acid-labile N- phosphorylations, has been identified in numerous prokaryotic and eukaryotic proteins.2 The only known protein Arg kinase is McsB in Gram-positive bacteria, which was characterized in 2009.3 McsB is a heat-stress responsive kinase and phosphorylates Arg residues in aggregated cytosolic proteins so that phosphoarginine (pArg) acts as a protein degradation tag recognized by the ClpC/ClpP protease system. Recently, bacterial-PROTAC was developed using pArg and ClpC- binding cyclic peptide to induce the degradation of the target protein.4 In contrast, no eukaryotic or mycobacterial protein Arg kinase has been identified despite the abundance of pArg sites in those organisms, hindering further studies of Arg phosphorylation. Herein, we report our progress in developing mechanism-based chemical probes to label and capture the elusive Arg kinase.
