Achieve Medium‐Range SST Forecast by Rolling 1‐Day Deep Learning

Abstract Deep learning has revolutionized short‐term Sea Surface Temperature (SST) forecasting, but often struggles with cumulative error propagation and operational complexity in medium‐range predictions. To achieve lightweight and temporally continuous SST forecast, this study...

Embedding-aware noise modeling of quantum annealing

Quantum annealing provides a practical realization of adiabatic quantum computation and has emerged as a promising approach for solving large-scale combinatorial optimization problems. However, current devices remain constrained by sparse hardware connectivity, which requires emb...

Portable Ocean Wave Energy Harvesters: Recent Advances, Challenges, and Future Perspectives

Portable Ocean Wave Energy Harvesters (POWEH) offer a potential approach for supplying autonomous low-power marine sensing systems; however, their long-term reliability, durability, and economic viability remain insufficiently demonstrated. But conventional wave energy converters...

Protective Potentials of Natural Products Against Vascular Dementia: A Comprehensive Review of Experimental Studies

ABSTRACT Vascular dementia (VaD), accounting for up to 20% of dementia cases globally, is primarily driven by chronic cerebral hypoperfusion (CCH), which leads to progressive cognitive impairment. Despite the increasing prevalence of VaD, effective treatments remain limited. Natu...

Temporal changes in ocular-surface bacterial contamination during cataract surgery and vitrectomy: effect of povidone–iodine

Postoperative endophthalmitis remains a serious complication of intraocular surgery, and reducing ocular-surface bacterial contamination is an important preventive strategy. We retrospectively evaluated temporal changes in ocular-surface/canthal irrigation-fluid culture positivit...

Iterative reconstruction algorithms for limited-angle tomography of thin slab objects: a performance review

Abstract As computed tomography (CT) applications have expanded, scenarios with restricted angular coverage, known as limited-angle tomography (LAT), are increasingly encountered. LAT commonly arises in industrial and non-destructive testing applications, where CT cannot fully tr...

Robust Functional Basis Neural Network Method With the Normalization

ABSTRACT This paper aims to develop a robust nonlinear model utilizing neural networks for function‐on‐function regression problems. The proposed framework is designed to enhance robustness in regression modeling by minimizing the impact of outliers in the response variable durin...

Comparative Efficacy of Diquafosol, Rebamipide, and Carboxymethylcellulose in Patients with Pre-existing Dry Eye Disease Undergoing Cataract Surgery

Purpose: To compare the clinical efficacy of 3% diquafosol, 2% rebamipide, and 0.5% carboxymethylcellulose (CMC) in patients with pre-existing dry eye disease (DED) undergoing cataract surgery. Methods: This retrospective study included 75 eyes of 75 patients with DED undergoing...

Association of Serum 1,25-Dihydroxyvitamin D Levels with Erythropoietin Resistance Index-Based Relative Erythropoiesis-Stimulating Agent Hyporesponsiveness in Pre-Dialysis Chronic Kidney Disease

Erythropoiesis-stimulating agent (ESA) hyporesponsiveness is a major challenge in the management of anemia in chronic kidney disease (CKD). This study evaluated the association between serum 1,25-dihydroxyvitamin D [1,25(OH)2D] levels and ESA responsiveness in patients with pre-d...

Beyond interactivity: dual relational pathways to fanship in the sports metaverse

Purpose This study examines how distinct forms of interaction in sports metaverse environments – fan-to-fan (FTF) and fan-to-star (FTS) – shape team fanship through different psychological mechanisms. By proposing a dual-pathway framework, we demonstrate that FTF interaction fost...

Association between Korean medicine use and analgesic and opioid utilization among patients with gastric cancer

Abstract Background Cancer-related pain is commonly managed with analgesics, including opioids; however, concerns regarding long-term use have underscored the need for complementary approaches. This study investigated the association between Korean medicine (KM) use and subsequen...

A Hybrid Magnetic Actuation System for Single‐Input Multistates Stabilization: Application to pH‐Responsive Drug Delivery

Targeted drug delivery requires precise carrier navigation and controlled payload release. We present an integrated robotic platform that combines a hybrid magnetic array with a pH‐responsive soft hydrogel. The array achieves single‐input, multistate stabilization: one current in...

Effects of Baegjinju Rice Flour Particle Size on Flour Functionality and Quality Characteristics of Batter-Coated Deep-Fat-Fried Chicken

Although Baegjinju rice flour is widely used in Korea, its functionality in meat batter systems remains unclear. This study investigated the effect of Baegjinju rice flour particle size (approximately 60–177 µm) on flour physicochemical and pasting properties, rice flour gel text...

Why Is Old‐Age Poverty Still High Despite Welfare Expansion? Evidence From South Korea

ABSTRACT Despite substantial increases in welfare expenditure since the 2000s, Korea continues to exhibit the highest relative old‐age poverty rate among advanced economies, while absolute poverty remains a significant concern. This study applies both relative and absolute povert...
