Scanning transmission electron microscopy (STEM) is an indispensable tool for atomic-resolution structural analysis for a wide range of materials. The conventional analysis of STEM images is an extensive hands-on process, which limits efficient handling of high-throughput data. Here, we apply a fully convolutional network (FCN) for identification of important structural features of two-dimensional crystals. ResUNet, a type of FCN, is utilized in identifying sulfur vacancies and polymorph types o

Van der Waals epitaxy on the surface of two-dimensional (2D) layered crystals has gained significant research interest for the assembly of well-ordered nanostructures and fabrication of vertical heterostructures based on 2D crystals. Although van der Waals epitaxial assembly on the hexagonal phase of transition metal dichalcogenides (TMDCs) has been relatively well characterized, a comparable study on the distorted octahedral phase (1T′ or Td) of TMDCs is largely lacking. Here, we investigate th

Objective：This study aims to identify the impact of social support on the relationship between loneliness and resilience for the elderly who are mentally sound, financially stable and living in a single household setting. Methods：A sample of 197 mentally healthy (Mini-Mental State Examination for Dementia Screening ≥-1.5 standard deviation and Geriatric Depression Scale <10) community-dwelling elderly 65 years of age or older was recruited. Multidimensional individual and interpersonal resilienc

Objective: This study aimed to investigate the risk factors of post-contrast acute kidney injury (PAKI) and the usefulness of the Mehran score for predicting PAKI in patients who underwent contrast-enhanced abdominopelvic computed tomography (CE-APCT) in the emergency department (ED). Methods: This was a retrospective observational study. Patients who underwent CE-APCT and had a follow-up creatinine test within 72 hours in the period January to June, 2017, were enrolled for the study. PAKI is de

Zipper entrapment injuries require a technique to safely and promptly release the entrapped tissues to prevent complications. Herein, we report an 8-year-old girl whose eyelid was successfully released from an entrapping zipper. She presented to the pediatric emergency department with her right upper eyelid entrapped in a zipper while getting dressed. She was distressed, anxious, and crying in pain. We have successfully removed the zipper using a lubricating gel, which provides local anesthesia.

An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space group, experimental conditions and quality measures.
