Logic-device-inspired mechanical computing system based on three-dimensional active components
Mechanical computing, utilizing mechanical deformation to perform calculations, has attracted significant attention as an innovative computing strategy for achieving high accuracy and exceptional physical robustness. However, its reliance on passive mechanical displacement limits its applicability for complex computations. This study presents a novel system that enables active light signal modulation through reversible mechanical deformation by integrating soft and 3D electronics. The proposed s

Polaronic Quasiparticles in the Valence-Transition Compound TmSe_{1-x}Te_{x}
Exotic quasiparticle states have been proposed in mixed-valent compounds exhibiting valence transitions. However, clear spectroscopic evidence identifying these states has remained elusive. Using synchrotron-based hard x-ray and extreme ultraviolet photoemission spectroscopy, we have probed the Tm 3d and 4f emissions in TmSe_{1-x}Te_{x}, where a Te concentration-dependent semimetal-insulator transition occurs alongside the valence transition. Our photoemission results, which are characteristic o

Depthwise-Separable U-Net for Wearable Sensor-Based Human Activity Recognition
In wearable sensor-based human activity recognition (HAR), the traditional sliding window method encounters the challenge of multiclass windows in which multiple actions are combined within a single window. To address this problem, an approach that predicts activities at each point in time within a sequence has been proposed, and U-Net-based models have proven to be effective owing to their excellent space-time feature restoration capabilities. However, these models have limitations in that they

Ultrasound localization microscopy lite (ULM lite): ultrasound localization microscopy with resource-efficient signal processing scheme
Ultrasound localization microscopy (ULM) is a groundbreaking, non-invasive imaging tool for monitoring vascular hemodynamics and neuronal activities in rodent models with exceptional spatial resolution. Despite its potential, the extensive data size required by the current ULM framework poses significant limitations to its broader applications. This study addresses these challenges by introducing sub-Nyquist sampling of the bandlimited radio-frequency (RF) signals, a method designed to reduce re

Edge-Server Workload Characterization in Vehicular Computation Offloading: Semantics and Empirical Analysis
Edge server-assisted computation offloading enables vehicles to leverage server compute resources to deliver connected services, overcoming the limitations of onboard resources. Understanding the compute workloads of edge servers is crucial for effective resource management and scheduling, yet this task is challenging due to the complex interplay of factors such as vehicle mobility and computation offloading patterns. To address this, we propose an empirical analysis framework that systematicall

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

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

Applications of flexible and stretchable three-dimensional structures for soft electronics
The development of devices that can be mechanically deformed in geometrical layouts, such as flexible/stretchable devices, is important for various applications. Conventional flexible/stretchable devices have been demonstrated using two-dimensional (2D) geometry, resulting in dimensional constraints on device operations and functionality limitations. Accordingly, expanding the dimensions in which such devices can operate and acquiring unique functionality that is difficult to implement in 2D pla
