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.

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.

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.
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.

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.

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.

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.
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.

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.
View Article and Find Full Text PDFBackground: 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.
