A brief review of hot-carrier dynamics in metal halide perovskites: mechanistic insights from time-resolved spectroscopy
Owing to their slow hot-carrier energy relaxation, metal halide perovskites have emerged as promising candidates for next-generation photovoltaics. This prolonged hot-carrier cooling allows excess energy to be harvested before dissipation as heat, thereby potentially enabling solar cells to exceed the Shockley-Queisser limit. Therefore, elucidating the mechanisms governing hot-carrier cooling is crucial for device optimization. Timeresolved spectroscopy enables observation of these ultrafast pro

Histone mark remodeling in cancer: an enhancer-centered perspective
Epigenetic deregulation is a defining feature of cancer, and histone modification remodeling plays a central role in reshaping malignant transcriptional programs. Histone marks collectively organize chromatin states that govern enhancer activity, promoter competence, and stability of repressive domains. Across diverse tumor types, redistribution of active and repressive histone modifications reconfigures regulatory landscapes that sustain oncogenic amplification, lineage plasticity, and adaptive

MLPH-mediated activation of dermal papilla IGF-1 signaling drives human hair shaft elongation and anagen induction
Introduction Hair loss (alopecia) is a multifactorial disorder that often causes distress. Approved therapies such as minoxidil and finasteride act indirectly and do not specifically target hair follicle (HF) cells. Erythropoietin (EPO), however, has been shown to activate dermal papilla (DP) cells via the erythropoietin receptor (EPOR), suggesting a potential role in hair follicle regeneration and hair growth. Objectives This study aimed to develop and validate Helix C-1–based EPO-derived pepti

Anisotropic Strain-Induced Centrosymmetry Breaking in Cubic Formamidinium Lead Iodide (α-FAPbI3) Thin Films
Organic-inorganic halide perovskites have emerged as promising materials for next-generation optoelectronic devices due to their exceptional photophysical properties. Among them, alpha-formamidinium lead tri-iodide (alpha-FAPbI3) with a cubic symmetry (space group of ) has garnered attention as a potential absorber in solar cells for its narrow bandgap and superior stability. The fundamental mechanisms governing its high performance have yet to be fully elucidated. In this study, we demonstrate

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

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
