Atomic-level Ru-Ir mixing in rutile-type (RuIr)O for efficient and durable oxygen evolution catalysis.

The success of proton exchange membrane water electrolysis (PEMWE) depends on active and robust electrocatalysts to facilitate oxygen evolution reaction (OER). Heteroatom-doped-RuO has emerged as a promising electrocatalysts because heteroatoms suppress lattice oxygen participation in the OER, thereby preventing the destabilization of surface Ru and catalyst degradation. However, identifying suitable heteroatoms and achieving their atomic-scale coupling with Ru atoms are nontrivial tasks.

Atomic-Scale Interface Modification in Complex Oxide Heterojunctions for Near-Infrared Photodetection.

Photodetectors that detect near-infrared (NIR) light serve as important components in contemporary energy-efficient optoelectronic devices. However, detecting the low-energy photons of the NIR light has long been challenging since the ease of photoexcitation inevitably involves increasing the background current in the dark. Herein, we report the atomic-scale interface modification in SrRuO/LaAlO/Nb-doped SrTiO (SRO/LAO/Nb:STO) heterostructures for NIR photodetection.

Predictive Factors of Emergency Department Length of Stay: Analyzing National Emergency Department Data.

Objective: This study aimed to identify and analyze the factors influencing Emergency Department Length of Stay (ED LOS) using a nationwide database to improve emergency care efficiency.

Methods: This retrospective study utilized data from the National Emergency Department Information System (NEDIS) in South Korea, covering 25,578,263 ED visits from 2018 to 2022. Patient demographics, clinical characteristics, and ED operational variables were examined.

Reversible Photomodulation of Two-Dimensional Electron Gas in LaAlO/SrTiO Heterostructures.

Long-lived photoinduced conductance changes in LaAlO/SrTiO (LAO/STO) heterostructures enable their use in optoelectronic memory applications. However, it remains challenging to quench the persistent photoconductivity (PPC) instantly and reproducibly, which limits the reversible optoelectronic switching. Herein, we demonstrate a reversible photomodulation of two-dimensional electron gas (2DEG) in LAO/STO heterostructures with high reproducibility.

Polymer-Covered Copper Catalysts Alter the Reaction Pathway of the Electrochemical CO Reduction Reaction.

The electrochemical CO reduction reaction (CORR) has attracted considerable attention recently due to the potential conversion of atmospheric CO into useful organic products by utilizing electricity from renewable energy sources. However, the selective formation of desired products only via CORR has been elusive due to the presence of a myriad of competing reaction pathways, thus calling for effective strategies controlling the reaction coordinates. The control of binding energies of the reaction intermediate, such as *CO, is pivotal to manipulating reaction pathways, and various attempts have been made to accomplish this goal.

Attention-Based 3D Human Pose Sequence Refinement Network.

Three-dimensional human mesh reconstruction from a single video has made much progress in recent years due to the advances in deep learning. However, previous methods still often reconstruct temporally noisy pose and mesh sequences given in-the-wild video data. To address this problem, we propose a human pose refinement network (HPR-Net) based on a non-local attention mechanism.

Various skin manifestations related to inflammatory bowel disease: A nationwide cross-sectional study on the Korean population.

Inflammatory bowel disease (IBD) presents with various extraintestinal manifestations. As part of them, various skin diseases are suggested to be related to IBD. We aimed to identify the epidemiology and risk of developing skin manifestations in patients with IBD.

Complete and transparent reporting of primary end points of randomized trials in the dermatology literature: A comparison of registered and published primary end points.

Background: Appropriate primary end points in randomized controlled trials (RCTs) improve the quality of the measurement and enable comparison of the findings with those of other trials.

Objective: To assess the quality of reporting primary end points in RCTs recently published in dermatology journals.

Methods: We identified 134 primary reports of RCTs among original articles in 4 dermatology journals published from January 2016 to December 2018.

A new treatment protocol of microfocused ultrasound for lower eyelid fat bulging.

Background: Microfocused ultrasound (MFU) causes tissue tightening by producing thermal injury zones and is used to treat various age-related changes including lower eyelid fat bulging.

Objective: To investigate the efficacy of a new treatment protocol of MFU for lower eyelid fat bulging.

Methods And Materials: We reviewed the medical records of all patients who began MFU for lower eyelid fat bulging from March 2017 to September 2018.

Natural course of new-onset urticaria: Results of a 10-year follow-up, nationwide, population-based study.

Background: Previous epidemiologic studies of the natural course of urticaria mainly focused on chronic spontaneous urticaria and were conducted at hospitals. The natural course of new-onset urticaria in the general population is unknown.

Methods: Patients with new-onset urticaria were identified from the National Health Insurance Service-National Sample Cohort data.

Constructing an Open-Access Bio-Signal Repository from Intensive Care Units.

Bio-signals can be crucial evidence in detecting urgent clinical events. However, until now, access to this data was limited. We aim to construct and provide a new open bio-signal repository with data gathered from more than 40 intensive care unit (ICU) beds.

Misclassification of study designs in the dermatology literature.

Background: The appropriate classification of study designs is important for review and assessment of the relevant scientific literature as a basis for decision making; however, little is known about whether study designs have been appropriately reported in the dermatology literature.

Objective: We aimed to validate the study designs in the dermatology literature and investigate discrepancies between author-reported and actual study designs.

Methods: We reviewed all issues of 3 major dermatology journals from January to December 2016.
