PURPOSE To evaluate the incidence of fellow-eye neovascularization in retinal angiomatous proliferation (RAP) in a Korean population and associated risk factors. METHOD This retrospective, observational study included 81 eyes (81 patients) diagnosed with unilateral RAP who were followed up for ≥12 months. The RAP diagnosis was based on an indocyanine(More)
Human umbilical cord mesenchymal stromal cells (hUC-MSCs) of Wharton's jelly origin undergo adipogenic, osteogenic, and chondrogenic differentiation in vitro. Recent studies have consistently shown their therapeutic potential in various human disease models. However, the biological effects of major pregnancy complications on the cellular properties of(More)
Multiplayer online battle arena games provide an excellent opportunity to study team performance. When designing a team, players must negotiate a proficiency-congruency dilemma between selecting roles that best match their experience and roles that best complement the existing roles on the team. We adopt a mixed-methods approach to explore how players(More)
We report a fast single element nonvolatile memory that employs amorphous to crystalline phase change. Temperature change is induced within a single electronic element in confined geometry transistors to cause the phase change. This novel phase change memory (PCM) operates without the need for charge transport through insulator films for charge storage in a(More)
Much of scientific progress stems from previously published findings, but searching through the vast sea of scientific publications is difficult. We often rely on metrics of scholarly authority to find the prominent authors but these authority indices do not differentiate authority based on research topics. We present Latent Topical-Authority Indexing(More)
In the use of single/few electrons in distributed storage for nonvolatile, low power and fast memories, providing statistical reproducibility at the nanoscale is a key challenge since relative variance has a radic<i>n</i> dependence and we are working with limited number of storage sites. We have used defects at interfaces of dielectrics to evaluate this(More)
