3D Fabrication of Fully Iron Magnetic Microrobots
Biocompatibility and high responsiveness to magnetic fields are fundamental requisites to translate magnetic small-scale robots into clinical applications. The magnetic element iron exhibits the highest saturation magnetization and magnetic susceptibility while exhibiting excellent biocompatibility characteristics. Here, a process to reliably fabricate iron microrobots by means of template-assisted electrodeposition in 3D-printed micromolds is presented. The 3D molds are fabricated using a modif

Self-supervised Monocular Depth Estimation Robust to Reflective Surface Leveraged by Triplet Mining
Self-supervised monocular depth estimation (SSMDE) aims to predict the dense depth map of a monocular image, by learning depth from RGB image sequences, eliminating the need for ground-truth depth labels. Although this approach simplifies data acquisition compared to supervised methods, it struggles with reflective surfaces, as they violate the assumptions of Lambertian reflectance, leading to inaccurate training on such surfaces. To tackle this problem, we propose a novel training strategy for

Style-Editor: Text-driven Object-centric Style Editing
We present Text-driven object-centric style editing model named Style-Editor, a novel method that guides style editing at an object-centric level using textual inputs.The core of Style-Editor is our Patch-wise Co-Directional (PCD) loss, meticulously designed for precise object-centric editing that are closely aligned with the input text. This loss combines a patch directional loss for text-guided style direction and a patch distribution consistency loss for even CLIP embedding distribution acros

FlexNeRFer: A Multi-Dataflow, Adaptive Sparsity-Aware Accelerator for On-Device NeRF Rendering
Neural Radiance Fields (NeRF), an AI-driven approach for 3D view reconstruction, has demonstrated impressive performance, sparking active research across fields. As a result, a range of advanced NeRF models has emerged, leading on-device applications to increasingly adopt NeRF for highly realistic scene reconstructions. With the advent of diverse NeRF models, NeRF-based applications leverage a variety of NeRF frameworks, creating the need for hardware capable of efficiently supporting these mode

Empirical Analysis of MAVLink Protocol Vulnerability for Attacking Unmanned Aerial Vehicles
Recently, unmanned aerial vehicles (UAVs), or the so-called drones, have been used in various applications. In particular, UAVs are used for rescue systems, disaster detection, and military purposes, as well as for leisure and commercial purposes. UAVs that are controlled over networks by ground control stations (GCS) can provide various services with expanded activity area. It is thus of critical importance to investigate the vulnerability of the drone system. In this paper, we focus on UAVs co

한국문학 번역과 번역 비평의 가능성 - The Vegetarian의 사례를 중심으로
본고에서는 한강의 소설 『채식주의자』의 영어본 텍스트인 The Vegetarian을 둘러싼 오역 논쟁을 메타적으로 검토하고, 가시화된 문학 번역을 둘러싼 논점을 예각화화면서, 그간 본격화되지 못했던 번역 비평을 시도하였다. The Vegetarian의 국제문학상 수상 이후로 문학 번역에 대한 논의가 시작되었으나, 그 논의는 오역 논쟁에 갇혀 문학 번역에 대한 심도 깊은 논의로 진전되지 못했다. 번역은 언어 간, 국가 간, 문화 간, 텍스트 간 권력 관계의 불균형성이 중첩된 위계 구조를 온몸으로 통과하는 일이며, 그 권력의 불균형성은 번역가의 위치성을 통해 가시화되는 것이기도 하다. 본고에서는 문학 번역을 번역의 정치성과 번역가의 위치성으로 가시화되는 권력 문제의 차원으로 이해하면서, 오역 논쟁을 문학 번역의 이론적 실천 과정과의 관련 속에서 비판적으로 검토하였다. The Vegetarian을 둘러싼 오역 논쟁의 이면에 가려진 권력의 문제는 번역 비평이 왜 번역의 윤리학과 정치학에 대

Recent Advances in Ultra-High-Speed Wireline Receivers with ADC-DSP-Based Equalizers
High-speed wireline data transceivers (TRX) with analog-to-digital converter (ADC) followed by digital signal processor (DSP) on the receiver (RX) equalizer became popular for applications requiring >100 Gb/s per-lane data rate over long-reach (LR) channels, especially for datacenter applications. With the digital-to-analog converter (DAC)-based transmitter (TX) including DSP-based TX signal processing, the overall structure of DAC/ADC-DSP-based wireline TRXs became similar to modulator/demodula

Oxygen Reduction Reaction (ORR) Activities of Pt-Ni Alloy Nanoparticles Supported on Graphene
Polymer electrolyte membrane fuel cell (PEMFC) has been studied widely due to its higher energy efficiency than a conventional internal combustion engine by generates electrical energy directly from chemical energy. However, the fuel cells faces lots of challenges to commercialization. Cost reduction and improvement of catalysts activities are two major problems impedes the commercialization. Since costly platinum has been used as a catalyst at both anode and cathode of fuel cells, it is require
