Beyond Binary Rewrite Decisions: Separating Rewrite-Intensity Control from Level Prediction in a Frozen-LLM Generation-and-Selection Pipeline for Korean Easy-Read Drafting

Editors of published Korean Easy-Read documents changed 50 aligned sentences by widely varying amounts (edit distance 0.39–0.89), motivating rewrite intensity as a control variable for large language models (LLMs). We ask whether a requested intensity is realized per sentence and...

Organellar Genome Analysis of the Red Alga Acrosorium flabellatum (Rhodophyta, Ceramiales, Delesseriaceae): Evidence of Gene Duplication and Group II Intron in cox1 Gene

Mitochondrial genomes (mitogenome) offer important information about evolutionary history, genomic diversity, and structural dynamics of Rhodophytes. The complete mitochondrial genome of Acrosorium flabellatum Yamada, 1930 (Delesseriaceae, Ceramiales), is reported in this study....

Field-based vital-capacity changes following a 12-week athletic skills model-informed curriculum: a retrospective non-randomised comparison in one Chinese primary school

This retrospective non-randomised comparison examined routine school records from 1,214 students in Grades 2–6 (607 per condition) in one urban public primary school in Southwest China. Curriculum allocation occurred at the level of 28 pre-existing physical-education (PE) teachin...

Installation Personas: A Persona-Centered Framework for AI-Driven Interactive Art Installations

Artificial intelligence (AI) is enabling interactive art installations to become increasingly adaptive and socially interactive, yet limited conceptual guidance exists for analyzing installations themselves as persona-like entities. In this study, the Installation Persona Framewo...

Temporal dissection of hepatitis C virus and orthoflavivirus infections by continuous luminescence monitoring

Virus infection is a dynamic process consisting of rapidly evolving viral and host events, yet conventional endpoint assays provide only fragmented snapshots of these processes. Here, we established a unified temporal framework for dissecting virus-host interactions by integratin...

Multisensor Characterization of Process Behavior During Underwater Laser Cutting of 100 mm Thick STS 304 Stainless Steel

Underwater laser cutting is a promising remote segmentation method for highly activated reactor internals because it enables non-contact cutting while maintaining water shielding. Although previous studies have demonstrated the feasibility of thick-section underwater laser cuttin...

Gate Electrode Engineering for Tunable Synaptic Plasticity in Organic Electrochemical Neuromorphic Devices

ABSTRACT Organic electrochemical transistors (OECTs) are widely studied for neuromorphic hardware, as their volumetric electrochemical doping couples ionic and electronic transport to mimic biological synaptic transmission. Research on OECT‐based artificial synapses has focused p...

Interactive dynamics of particulate and dissolved organic matter under sustained hypoxia conditions in a semi-enclosed bay (Jinhae Bay)

We investigated the isotopic variation of particulate and dissolved organic matter (OM; δ 13 C POC , δ 15 N PN , δ 13 C DOC ) associated with the frequent occurrence of hypoxia in a semi-enclosed bay (Jinhae Bay, South Korea). During the hypoxic period (August–October 2024), surf...

A Multi-Stage Framework for Story-Based Question Generation, Evaluation, and Cognitive Domain Assignment for Potential Cognitive Training Applications

This study proposes a multi-stage framework for generating, evaluating, refining, and assigning cognitive domains to story-based candidate questions for potential cognitive training applications. Using 20 FairytaleQA stories, 1668 questions were initially generated, of which 1351...

A carbonate/H2O2 surrogate for representing thermal runaway and state-of-charge effects in lithium-ion battery fires

For fire hazard assessment of lithium-ion batteries (LIBs), the autoignition of carbonate/H 2 O 2 mixtures in a transient constant-volume reactor was numerically simulated to investigate their potential as simplified reactive surrogates for selected LIB fire characteristics. The...

Bio‐Inspired Internal Stress Engineering for Microscale Surface Cracking in Sensitive Strain Sensors

ABSTRACT The fabrication of microscale cracks on flexible substrates is a crucial step for potential applications such as human–machine interfaces, biosignal analysis, and structural health monitoring. However, existing crack fabrication methods predominantly rely on externally a...

Marine-Derived Bioactive Peptides as Immunomodulatory Agents: Organoid-Based Platforms and Translational Perspectives

Marine environments harbor immense biodiversity that yields peptides with potent immunomodulatory, antioxidant, and anti-inflammatory activities. These marine-derived immunomodulatory peptides act as molecular mediators of host defense and immune homeostasis across taxa ranging f...

Operational monitoring of vegetation drought considering the propagation processes between various meteorological drought indices and vegetation indices

Abstract Vegetation drought (VD) is a condition in which vegetation experiences stress due to various meteorological factors. Several meteorological drought indices (MDIs) have been developed and applied to quantify the effects of such drought. However, researches on which meteor...

Mitogenomic characterization and phylogenetic placement of the mottled wood-owl strix ocellata with gene rearrangement patterns in strigiformes

Abstract Owls (order Strigiformes) represent a highly specialized lineage of nocturnal raptors, within which the genus Strix (family Strigidae) comprises several widely distributed species despite the limited availability of comprehensive mitogenomic data. In this study, the comp...

Offshore listing of Korean equity index derivatives and domestic market adjustment: evidence from the KOSPI 200 index

This study examines how the offshore listing of Korean equity index derivatives is associated with the domestic KOSPI 200 market. We focus on the launch of Morgan Stanley Capital International (MSCI) Korea Index Futures on Eurex Exchange on July 14, 2025, which created a regulate...

Comparative Evaluation of SELECT and Generalized Additive Models for Estimating Gillnet Selectivity of Snow Crab (Chionoecetes opilio) in the East Sea of Korea

This study evaluated snow crab (Chionoecetes opilio) gillnet selectivity using the traditional Share Each Length’s Catch Total (SELECT) framework and a generalized additive model (GAM). Comparative fishing experiments were conducted in the East Sea of Korea using four stretched m...

Joint Power Allocation and Power-Splitting Optimization for Underlay D2D Communications in SWIPT-Enabled DF Relay Networks

This paper investigates underlay device-to-device (D2D) communication in a simultaneous wireless information and power transfer (SWIPT)-enabled two-hop decode-and-forward cellular relay network. The D2D transmitter transmits both information and cancelable energy signals, with th...

Consumer Preferences for Electric Vehicle Fuel Taxation: The Role of Revenue Recycling and Tax Salience in South Korea

The rapid diffusion of electric vehicles (EVs) is weakening the conventional fuel tax base, creating new challenges for transport-energy taxation. Although South Korea does not currently tax EV charging electricity, such taxation is becoming increasingly relevant as EV adoption e...

H‐Likelihood Approach on the Joint Frailty Model for Clustered Bivariate Survival Data
