Automatic Operation Algorithm for Stormwater Pumping Stations Based on Heuristic-Guided Reinforcement Learning

Automated operation of urban stormwater pumping stations is a sequential decision-making problem that must prevent detention-basin overflow during intense rainfall while coordinating pump switching, pump use, and dry-running risk. This study proposes a heuristic-guided reinforcem...

Life-threatening diffuse alveolar hemorrhage associated with Rhinovirus infection and the potential role of corticosteroids in immunocompetent patients

Rationale: Diffuse alveolar hemorrhage (DAH) is a rare but potentially fatal condition characterized by bleeding into alveolar spaces, most often associated with autoimmune disease or severe infection. Rhinovirus is a common cause of upper respiratory tract infection but is rarel...

Microfluidic Focusing of Heterogeneous Bacterial Immunocomplexes for Reproducible SERS Immunoassays

Abstract Magnetic bead-based surface-enhanced Raman scattering (SERS) immunoassays enable sensitive and multiplexed bacterial detection. However, bacterial targets form heterogeneous magnetic bead–bacterium–SERS nanotag immunocomplexes that vary in size, morphology, and nanotag l...

Atomic-Layer-Deposited Interlayers Enabling Interfacial Band Tuning in Vapor Transport Deposition-SnS/CdS Solar Cells

Abstract Severe interfacial recombination remains a key barrier limiting carrier collection in SnS thin-film solar cells. Thus, in this study, atomic layer deposition (ALD)-based thin oxide interlayers are engineered at the SnS/CdS heterojunction. The applicability of ZnO, SnO2,...

Spatially Complementary In‐Plane Lattice Strain Engineering for Reduced Contact Resistance and Enhanced Ferroelectric Switching in Van Der Waals α‐In 2 Se 3 Ferroelectric Semiconductor Field‐Effect Transistors

ABSTRACT α‐In 2 Se 3 ferroelectric semiconductor field‐effect transistors (FeS‐FETs) offer attractive non‐volatile memory characteristics but are limited by high source/drain (S/D) contact resistance and inefficient ferroelectric polarization switching. Here, we demonstrate a low...

Effects of Malic Acid Vase Solution on the Postharvest Quality and Vase Life of Cut Rose ‘Candlelight’ Grown Under Low-Light Conditions

Low-light conditions during winter cultivation reduce the postharvest quality of cut roses, highlighting the importance of effective postharvest management. This study investigated the effects of malic acid (MA) and sucrose (Su) vase solutions on the postharvest quality and vase...

Psychometric evaluation of the Korean version of the Advance Care Planning Practice Scale among nurses

This study translated the Advance Care Planning Practice Scale into Korean and evaluated its psychometric properties using a sample of Korean nurses. This was a methodological study. The Advance Care Planning Practice Scale was translated using a forward–backward procedure and ex...

CoMA: Condition-Modulated Context–Knowledge Attention for Empathetic Dialogue Generation

Empathetic response generation requires a model to balance emotional appropriateness with contextual grounding. However, the performance of emotion recognition remains relatively limited, which may lead to cascading errors in generating empathetic responses. To avoid error propag...

Phase IIa Trial of Locoregional High-Dose Autologous Natural Killer Cell Therapy Combined with Hepatic Arterial Infusion Chemotherapy for Locally Advanced Hepatocellular Carcinoma

PurposeHepatocellular carcinoma (HCC) refractory to locoregional therapies remains a major clinical challenge.This study evaluated the efficacy and safety of locoregional high-dose autologous natural killer (NK) cell therapy combined with hepatic arterial infusion chemotherapy (H...

Temporal regulation of activin, follistatin, and growth differentiation factor 15 in the liver and circulation during high-fat diet–induced fatty liver disease

Metabolic dysfunction-associated steatotic liver disease (MASLD) develops over time, yet most hepatokine studies are cross-sectional.We investigated the temporal regulation of the activin-follistatin axis and growth differentiation factor 15 (GDF15) in high-fat diet (HFD)-induced...

Wireless Monolithic Tandem Leaf for Semi-Artificial Photosynthesis

Abstract Biocatalytic semi-artificial photosynthesis enables selective solar-to-chemical conversion by harnessing photoelectrocatalytic platforms to drive redox biocatalysis. However, the reliance of most photoelectrochemical (PEC)-based devices on transparent conductive oxides (...

Role of Mn3+/Mn4+ redox-coupled oxygen vacancy modulation in SnO2 nanoarchitectures for ultrasensitive acetone detection

Acetone (CH 3 COCH 3 ) is a ubiquitous volatile organic compound in industrial and laboratory settings; however, its high volatility and toxicity necessitate advanced monitoring to ensure human health and occupational safety. In this work, we report a highly sensitive and selecti...

Comparison of Neurophysiological Characteristics Using Heart Rate Variability Between Patients With Korean Hwa-byung and Healthy Individuals

Objective Hwa-byung (HB) is a syndrome associated with stressful events within Korea’s social and cultural contexts. The clinical symptoms of HB may be associated with autonomic imbalance. This study investigated the neurophysiological characteristics of HB by comparing heart rat...

Pathological calcium overload impairs skeletal muscle regeneration through sustained NFAT-dependent proliferative signaling

Abstract Skeletal muscle regeneration requires coordinated myoblast proliferation and differentiation. Calcium dysregulation is commonly observed in aging and disease-associated muscle weakness; however, its impact on myogenic progression remains unclear. In this study, we invest...

Surface-Mediated Immunomodulation by Electrostatic Immobilization of Naproxen on Plasma-Aminated Poly(ε-caprolactone) Films Rescues Osteogenic Differentiation via Attenuation of NF-κB Signaling

Abstract Chronic inflammation following biomaterial implantation often leads to fibrous encapsulation and compromised osseointegration, particularly in clinically inflamed environments. We developed a surface-functionalized poly(ε-caprolactone) (PCL) platform to modulate the earl...
