Role of acidic and alkaline cleaning solutions on ceria removal and brush-mediated cross-contamination during post-STI CMP cleaning

Ceria-based slurries used for shallow trench isolation (STI) chemical mechanical planarization (CMP) leave residual particles that must be effectively removed during post-CMP cleaning to prevent wafer defects and cross-contamination. Although polyvinyl acetal (PVAc) brush scrubbi...

The Firstborn Who Never Stood in His Place: Reuben’s Self-Undermining Leadership in the Jacob Family Narrative (Gen 29–50)

Reuben is the least studied of the displaced firstborn sons of Genesis whose material can sustain a reading of character, and his scenes have been read piecemeal. This article reads every scene in which he acts (30:14a; 35:22a; 37:21–22, 29–30; 42:22; 42:37), with the verdict of...

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...

Molecular Mechanism of AtCAX3-Induced BPA Tolerance in Plants

Cation/H+ Exchangers (CAXs) are involved in the sequestration of cations such as Ca2+, Mn2+, Li+, Zn2+, and Cd2+ from the cytosol into the vacuole using proton gradients. Our previous studies demonstrated the involvement of AtCAX3 in Cd2+ tolerance. In this study, we investigated...

Evaluation of postural control during quiet standing and aiming tasks in professional and novice archers

Postural stability is essential for archery performance, as reduced center of pressure (COP) fluctuations enable precise bow alignment and shot accuracy. Although prior studies have shown that professional archers exhibit smaller COP displacements and variability than novices, th...

High-Pressure Deuterium Annealing Enables Robust Trap Passivation in ALD HfO2/Si MOS Capacitors under High-Temperature Bias Stress

Abstract The continuous scaling down of semiconductor devices has driven the replacement of SiO2-based gate insulators with HfO2 deposited via atomic layer deposition (ALD) to mitigate the leakage current induced by direct tunneling. However, HfO2 thin films deposited via ALD con...

The Value of an Attorney: Collateral Source Rule Changes as an Invalid Instrument

ABSTRACT The value of lawyers to their clients is notoriously difficult to estimate because of endogeneity. We utilize modifications to the collateral source (CS) rule that require reducing trial awards by the amount of payments from first‐party insurance as an instrument for hir...

Efficacy and safety of a combined extract of Paeonia lactiflora and Salvia miltiorrhiza (USCP-SL22) on fasting triglyceride reduction in adults: A randomized, double-blind, placebo-controlled trial

Elevated fasting triglyceride (TG) levels are a major risk factor for cardiovascular disease. This multicenter, randomized, double-blind, placebo-controlled trial evaluated the efficacy and safety of a combined extract of Paeonia lactiflora and Salvia miltiorrhiza (USCP-SL22) in...

2025 Korean Guidelines for Cardiopulmonary Resuscitation: Part 7. Pediatric basic life support: a secondary publication

Pediatric cardiac arrest primarily arises from asphyxia in infants and trauma in older children, contrasting with adult etiologies dominated by cardiac events. This underscores prevention as the cornerstone of pediatric basic life support, through injury mitigation like child res...

2025 Korean Guidelines for Cardiopulmonary Resuscitation: Part 8. Pediatric advanced life support: a secondary publication

The 2025 Korean pediatric advanced life support guideline update introduces clinically important revisions emphasizing airway strategy, physiologic resuscitation targets, post-cardiac arrest hemodynamics, neuroprotection, and extracorporeal support. In out-of-hospital pediatric c...

Fasting Duration and Differences Across Routine Laboratory Tests

Importance Fasting before blood collection is widely practiced to reduce preanalytical variability, yet whether fasting-related differences are clinically meaningful across a broad panel of routine analytes has not been systematically evaluated using clinical data. Objective To e...

Predicting ground motion intensity measures in Japan using a hybrid artificial neural network integrated with Taguchi optimization

Despite the availability of extensive strong-motion recordings in Japan, machine learning (ML)-based ground-motion models (GMMs) capable of consistently predicting a broad range of intensity measures (IMs) remain limited. This study develops a hybrid artificial neural network (AN...

Susceptibility‐Guided Triple Therapy Achieves High Helicobacter pylori Eradication Regardless of Duration

ABSTRACT Background and Aim Although clarithromycin resistance is a major cause of empirical triple therapy failure for Helicobacter pylori eradication, the clinical relevance of amoxicillin susceptibility remains uncertain. We first compared eradication outcomes between empirica...

Thin Thoracodorsal Artery Perforator Free Flap for Scalp Resurfacing After Malignant Skin Tumor Excision

ABSTRACT Background Scalp defects after malignant tumor excision often require free tissue transfer for durable coverage. The thoracodorsal artery perforator (TDAP) flap remains underused despite its suitability for thin elevation. Methods Fourteen patients (6 men, 8 women; mean...

Solvent‐Free Synthesis of Ultrabright Carbon Dots With Near‐Unity Quantum Yield for High‐Performance Light‐Emitting Diodes

ABSTRACT Conventional liquid‐phase syntheses of carbon dots (CDs) often involve complex solvent‐precursor interactions that induce structural and spectral heterogeneities, severely limiting their optoelectronic performance. Herein, we report a highly controlled, solvent‐free, sin...

New record of the family Porcellidiidae Boeck, 1865 (Harpacticoida, Copepoda) in Korea

Lee, Seunghan, Kim, Jaehyun, Lee, Wonchoel (2023): New record of the family Porcellidiidae Boeck, 1865 (Harpacticoida, Copepoda) in Korea. Journal of Species Research 12 (1): 27-37, DOI: 10.12651/JSR.2023.12.1.027

Phase-Programmed Charge Routing Governs Kinetic and Thermodynamic Molecular Selectivity for Chemiresistive Sensors

Abstract Controlling molecular selectivity in chemiresistive gas sensors remains a fundamental challenge, particularly for chemically analogous analytes that generate indistinguishable electronic responses. Here, we demonstrate that polymorph-engineered MoS2/SnO2 heterointerfaces...

Long- and short-run determinants of metro ridership in Seoul: A vector error correction model approach

The metro system is essential infrastructure underpinning urban sustainability and citizen mobility. The Seoul metro system has experienced continuous infrastructure expansion, multiple policy changes, and major external shocks over the past 25 years. This study examined the shor...

Training investment indicators beyond cost: analyzing the impact of training on organizational outcomes

Organizations invest heavily in employee training, yet firms and firm-level research typically evaluate that investment by cost alone. Cost, however, reveals little about how training is delivered, how widely it reaches employees, or whether the firm has the resources to translat...

One-pot chemical vapor deposition (OP-CVD) of period-4 transition metal oxide catalysts supported on CeO2: A comparative study for CO Oxidation

Ceria-supported catalysts have been used in catalysis, however, facile synthesis routes are a necessity. Herein, we develop transition metal oxide catalysts (TMO x ) over CeO 2 support via one-pot chemical vapor deposition (OP-CVD), where period 4 TM: Fe, Co, Ni, and Cu were cons...
