Material decomposition-based improved normalized metal artifact reduction method (MD-NMAR) in photon counting CT
Photon counting computed tomography (PCCT) acquires multiple images of different energy ranges from a single computed tomography (CT) scan. It provides us with spatial and spectral information not available from conventional CT, making it possible for further analysis in the metal artifacts reduction (MAR). This study aims to develop a method to reduce metal artifacts in PCCT using material decomposition. We use the normalized MAR (NMAR) method and calibration data to obtain the initial basis ma

High voltage cathode materials for rechargeable magnesium batteries: Structural aspects and electrochemical perspectives
Rechargeable magnesium batteries (RMBs) are a cutting-edge energy storage solution, with several advantages over the state-of-art lithium-ion batteries (LIBs). The use of magnesium (Mg) metal as an anode material provides a much higher gravimetric capacity compared to graphite, which is currently used as the anode material in LIBs. Despite the significant advances in electrolyte, the development of cathode material is limited to materials that operate at low average discharge voltage (<1.0 V vs.

Mechanoluminescence: Mechanisms, emerging applications, and future prospects
Mechanoluminescent (ML) materials have gained significant attention in recent years due to their promising applications in force sensing, biomedical diagnostics, structural health monitoring, anti-counterfeiting, lighting, and intelligent artificial skin. These materials are capable of emitting visible light in response to mechanical stimuli such as pressure, tension, or friction, making them ideal candidates for advanced sensing technologies. Their advantages include rapid response time, high d

LAMP: Implicit Language Map for Robot Navigation
Recent advances in vision-language models have made zero-shot navigation feasible, enabling robots to interpret and follow natural language instructions without requiring labeling. However, existing methods that explicitly store language vectors in grid or node-based maps struggle to scale to large environments due to excessive memory requirements and limited resolution for fine-grained planning. We introduce LAMP (Language Map), a novel neural language field-based navigation framework that lear

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

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
